TECHNICAL FIELD:
The present disclosure relates to an automatic insertion of spring. More particularly the present disclosure relates to a method of automatic insertion of springs without human intervention and without damaging the springs.
BACKGROUND:
In general, vehicles comprise of a cylindrical lock which are used to lock the vehicle by means of a key. In the cylindrical lock, a case is present which act as a housing where all the components are mounted inside the case. A keyhole is present in cylindrical lock wherein the key is inserted and turned to unlock/ lock as per requirement. The keyhole is having at least four cavities of equal diameter for housing magnets which are spring loaded. In the existing mechanism, the springs are loaded in the case manually where one or more person are involved to separate each of the spring, detangle it from the lot springs which are scattered around the workstation as shown in figure 1 and figure 2. There is also a requirement of extra space for the existing setup. The method of separating each spring from a lot of spring is time consuming and due to human intervention, the springs are damaged. This leads to the wastage of spring. Also, one or more person is required to put the spring inside case in accordance with the code in the assembly line.
Thus in view of the above there has been a need to develop a method so to overcome the existing mechanism.

In one more embodiment of the present disclosure wherein the spring is made by brass.
In another embodiment of the present disclosure the article (2) is a spring made of any metal or alloy.
Figures 3-5 illustrates the method of automatic insertion of spring in the cylindrical lock. In the present disclosure, the springs are fed into a bowl feeder in which the air is supplied at specific pressure (4-6 kgf/cm2) through a nozzle. As shown in figure 4, the nozzle is positioned at the bottom two end of the hopper. The nozzle supplies air at a specific pressure and a pressure regulator is also mounted to check the value of pressure inside the bowl feeder. Pressure regulator keeps a check of the pressure inside the hopper and regulates it according to the requirement. The tangled springs moves upward due to pressure of air and get hit on a wall provided in the bowl feeder

by which the tangled springs get detangled. The wall is a vertical structure having two ends. One end is connected with the bottom surface of the bowl feeder whereas other end is connected with an extended protrusion. The tangled spring while moving upwards strikes the surface of the extended protrusion and due to impact of moving springs and stationary extended protrusion, the springs are detangled.
The bowl feeder vibrates at the optimum vibration by which the springs start to moves in clockwise or anticlockwise direction from the base of the bowl feeder to a connector via conveying path in the feeder. The repetitive, or vibratory, movement of the feeder bowl causes the spring therein to propagate in a desired direction (clockwise or anti clockwise) direction. The connector present at the top of the bowl feeder allows single spring to move from the bowl feeder into pipes through which it reaches the case. The detangled spring moves on the conveying path through a pipes into a spring feeding mechanism. The case is located on a locator which is mounted below a fixture.
The code is generated by the PLC based on which three springs are inserted in any of the four holes of the case in two ways. According to the code, at first the feeding mechanism moves downwards and matches hole of the spring feeding mechanism to the hole of the case. The spring feeding mechanism comprises of four pneumatic cylinders in which first pneumatic cylinder moves the feeding system down and up to the case. The other two pneumatic two cylinder stop, grab and releases a single spring in to the case holes according to the code generated by the PLC. Fourth cylinder moves the mechanism forward and backward to match with the other two holes. The same is repeated for the other two holes. The pneumatic cylinder clamp the case and insert 1 or 2 springs according to the code in to the two hole of the case then it move upward and re clamp the case and insert 1 or 2 springs according to the code in to the other two hole of the case. The case having brass springs move to next station. This process repeat again with the new case. Figure 6 illustrates the mounting of the springs in the case as described by above process.

Advantages:
(a) The primary advantage of the present disclosure is to reduce the human intervertion and automate the process of insertingh the spring in the case.
(b) One more advantage of the present proces is to reduce the wastage of springs.
(c) The space required on the assembly line is reduced and no extra space is needed.
