[0019] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0020] The present invention relates to a cutting saw blade repairing device that is capable of sharpening a cutting saw blade appropriately without any requirement of physical efforts in order to repair the blade to allow the user to cut any objects that the user desires.

[0021] Referring to Figure 1, an isometric view of a cutting saw blade repairing device is illustrated, comprising a L-shaped member 101 having a hollow region in the horizontal portion of the member 101, a pair of L-shaped bars 102 attached on downwardly directed sliding units 103 installed at an upper surface of the hollow region, ends of the bars 102 are provided with motorized abrasive rollers 104, a pair of telescopic links 105 installed on opposing surfaces of the hollow region by means of ball and socket joints 106 having suction cups 107 at the ends, an artificial intelligence-based imaging unit 108 installed on the member 101, a microphone 109 provided on the member 101, and a touch-enabled display unit 110 provided on the member 101.

[0022] The proposed device comprises of an L-shaped member 101 having a hollow region encased with various components associated with the device arrange in sequential manner that aids in repairing cutting saw blade. Herein, a perpendicular part of the member 101 provides a gripping by a user. Upon gripping the member 101 by the user, the user requires to activate the device manually by pressing a button associated with the device and assembled with the member 101. The button is type of a switch that is internally connected with the device via multiple circuits that upon pressing by the user, the circuits get closed and starts conduction of electricity that tends to activate the device and vice versa. After activating of the device by the user, a microcontroller associated with the device generates a commands to operate the device accordingly.

[0023] Alternatively the user accesses a touch-enabled display unit 110, integrated with the member 101 for giving input commands regarding turning on or turning off the sharpening process. The display unit 110 works by using LCD (liquid crystals) that are manipulated by electric currents to control the passage of light through the display panel. When an electric current is applied, the liquid crystals align in a way that either allows light to pass through or blocks it, creating the images and colors that is being visible in the LCD of the display unit 110 regarding the turning on or turning off the sharpening process that is further change the electric charge at the location of the touch to register as input. The input is stored in the microcontroller to process the input. Based on given input, the microcontroller activates or de-activates the device.

[0024] Upon activating the device, an artificial intelligence-based imaging unit 108 integrated with the member 101 detects a bent saw blade. The imaging unit 108 comprises of a camera and processor that works in collaboration to capture and process the images in vicinity of the member 101. The camera firstly captures multiple images of the vicinity of the member 101, wherein the camera comprises of a body, electronic shutter, lens, lens aperture, image sensor, and imaging processor that works in sequential manner to capture images of the vicinity of the member 101. After capturing of the images by the camera, the shutter is automatically open due to which the reflected beam of light coming from the surrounding due to light is directed towards the lens aperture. After then the reflected light beam passes through the image sensor. The sensor now analyzes the beam to retrieve signal from the beams which is further calibrate by the sensor to capture images of the vicinity of the member 101 in electronic signal.

[0025] Upon capturing images, the imaging processor processes the electronic signal into digital image. When the capturing is done, the processor associated with the imaging unit 108 processes the captured images by using an artificial intelligence protocols to retrieve data from the captured image in the form of digital signal. The data is now transmitted to the microcontroller based on which the microcontroller acquires the data and analyze to detect the bent saw blade. Based on detection, the microcontroller generates commands to activate a speaker inbuilt with the member 101 to alert for the user regarding straightening of the blade before sharpening of the blade.

[0026] The speaker, herein includes a diaphragm, which is typically made of a lightweight and rigid material like paper, plastic, or metal to vibrate and produce sound waves when electrical signals are fed to it for notifying the user. After passing of the electrical signal through a voice coil suspended within a magnetic gap of the speaker, it generates a magnetic field that interacts with the fixed magnetic field produced by a magnet assembly associated with the voice coil. As the electrical current varies, the magnetic field produced by the voice coil changes, resulting in the voice coil and attached cone/diaphragm moving back and forth. This movement creates pressure variations in the surrounding air, generating sound waves to generate the audible sound to notify the user to straight the blade before sharpening.

[0027] Upon straitening of the blade, the user accesses a microphone 109 linked with the member 101 for giving voice commands regarding sharpening of saw blade. The microphone receives sound waves generated by energy emitted from the voice command in the form of vibrations. After then, the sound waves are transmitted towards a diaphragm configured with a coil. Upon transmitting the waves within the diaphragm, the diaphragm strikes with the waves due to which the coil starts moving the diaphragm with a back-and-forth movement in presence of magnetic field generated from the coil. After that the electric signal is emitted from the coil due to back-and-forth movement of the diaphragm which is further transmitted to the microcontroller linked with the microphone to process the signal to analyze the signal for detecting voice command given by the user.

[0028] Upon processing the voice commands, the microcontroller actuates an MID (magneto-inductive displacement) sensor integrated in the member 101 detects sharpness of the blade. The MID sensor operates by measuring changes in the magnetic field between a coil and the saw blade. As the blade moves, it alters the inductance of the coil, allowing for precise measurement of displacement. Based on the displacement, the sensor calibrates to detect the sharpness of the blade. After that the microcontroller actuates a pneumatic unit integrated with a pair of telescopic links 105 installed on opposing surfaces of the hollow region to extend for gripping the blade by suction cup integrated with each of the link.

[0029] The pneumatic unit, disclosed herein comprises of an air compressor, air cylinder, air valves i.e. Inlet and outlet valve and piston that works in collaboration to aid extension and retraction of the links 105. The air compressor is coupled with a motor that gets activated by the microcontroller to compress the air from surroundings upon entering from the inlet valve to compressed and pumped out via the outlet valve. The air valve allows entry or exit of the compressed air from the compressor. Furthermore, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the cylinder and due to the increase in the air pressure, the piston extends. And upon closing of the valve, the compressed air exit out from the cylinder thereby decreasing the air pressure of the cylinder.

[0030] The increasing and decreasing of the air pressure from the cylinder aids in extension and retraction of the piston that turns in aiding extension and retraction of the links 105 to apply pressure over the blade by the suction cups 107. Upon pressing of the cups 107 on the blade, the cups 107 create partial vacuum within the cups 107 by squeezing out air from the cups 107 due to a negative pressure is generated inside suction area. Herein, atmospheric pressure outside the cups 107 presses down low-pressure area inside the cups 107 to generate suction to adhere the blade in an appropriate manner.

[0031] After that the microcontroller actuates sliding units 103 integrated at an upper surface of the hollow region to move a pair of L-shaped bars 102 attached on the sliding units 103 over the blade. The sliding unit 103 comprises of a rail unit that provides a guided path for linear movement. The rail unit usually includes a pair of parallel rails or tracks, along which the sliding unit 103 moves. The slider carriage, also called a stage or platform equipped with a mechanism to minimize friction and ensure smooth motion. The sliding unit 103 incorporates a motor and a drive mechanism to generate linear motion. The motor is connected to a drive mechanism, such as a belt, lead screw, or ball screw. The drive mechanism converts the rotational motion of the motor into linear motion, propelling the slider carriage along the rail unit to translate the bars 102 over edge of the saw blade.

[0032] Simultaneously, the microcontroller actuates motorized abrasive rollers 104 integrated with the end of the bars 102 to rotating contact with the edge for sharpening the blade. The rollers 104 e coupled with motor that is activated by the microcontroller to rotate the rollers 104 with specified speed in contact with the edge of the blade to sharp the blade. Additionally, based on detecting the sharpness of the blade, if the detected sharpness level below a threshold sharpness, then the microcontroller actuates ball and socket joints 106 integrated with the links 105 for orienting the rollers 104 as per angle of the blade detected by an angle sensor integrated with the member 101 for sharpening the blade properly. The angle sensor works based on the principle of detecting changes in magnetic fields or optical signals.

[0033] By analyzing changes in magnetic fields or optical signals, the angle sensor accurately determines the angle or position of the blade with respect to the rollers 104. This information is then further transmitted to the microcontroller in the form of digital signal to analyze and detect the angle of the blade with respect to the rollers 104 based on that the ball and socket joint 106 orient the links 105 to sharpen the blade. The ball and socket joint 106 is a mechanical arrangement consists of a ball-shaped component that fits into a socket, with a motor providing the necessary power to drive the rotation to provide angular movement to the links 105 to aid the rollers 104 to do sharpening operation over the edge of the blade in appropriate manner.

[0034] A battery (not shown in figure) is associated with the device to offer power to all electrical and electronic components necessary for their correct operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so they effectively carry out their appropriate functions.

[0035] The present invention works best in following manner that possess the L-shaped member 101 having a hollow region in the horizontal portion of the member 101 in which the perpendicular part of the member 101 enables a gripping by a user. Herein, the microphone 109, linked with the microcontroller, receives an audio command from the user regarding sharpening of saw blade to trigger the microcontroller to actuate the MID sensor to detect a sharpness of the blade to actuate the links 105 to extend and grip the blade by the suction cups 107 and the rollers 104 to rotate and the sliding units 103 to contact the rollers with the blade for sharpening. Also, if the detected sharpness is below a threshold sharpness, wherein the ball and sockets angle the blade for sharpening as per an angle of the blade detected by an angle sensor provided on the member 101. Herein, the touch-enabled display unit 110, aids the user to provide touch input regarding turning on or turning off the sharpening process. During repairing operation, the artificial intelligence-based imaging unit 108, detects a bent saw blade to trigger the microcontroller to actuate the speaker to generate an audio alert for the user regarding straightening of the blade prior to sharpening.
