FIELD OF INVENTION

[0001] The present invention relates to a surface inspection system, and more particularly the surface inspection system configured to monitor surface quality of a workpiece such as a steel strip.

BACKGROUND
[0002] Due to global competition in the automotive sector, the quality of skin panels of motor vehicles has become one of the main determinant factors in the purchase process decision. Skin panels of motor vehicles are aesthetics products and have stringent quality requirements. Traditionally, surface quality inspection of the skin panels was carried out manually by human inspectors at skin pass mills where these skin panels were manufactured. However, the quality of inspection was less accurate and was far from satisfaction because of low productivity and reliability. As a preventive measure, surface inspection systems were used to overcome the drawbacks of human inspection and to accurately monitor the surface quality of steel strips (used to make skin panels) based on machine-vision technology. These surface inspection systems utilize cameras and lights mounted on fixed frames to inspect the top and bottom surfaces of the steel strips.
[0003] Lights of these systems play an important role, since these lights are reflected from bridle rolls and are captured by camera. Images of defects are captured and analyzed through image processing systems to inspect the surface quality of the steel strips. In new production lines these systems can be strategically placed so as to not interfere with activities such as threading operations or cleaning activities etc. However, due to space constraints in old and existing production lines, commissioning of new surface inspection systems has become a major challenge, as rearranging the old and existing production lines to accommodate the surface inspection systems was found to be not economical. Further, as the cameras and lights of the existing surface inspection systems are to be positioned at fixed locations, even when used in old and new production lines, there was a possibility of interference (hurdles) with activities such as strip threading operation, dent cleaning of bridle rolls etc. Hence, it is desirable to develop a surface inspection system which can be used in both the old and new production lines, which can mitigate the above-mentioned hurdles and accurately inspect the surface quality of skin passed steel strips.
OBJECTIVE OF INVENTION
[0004] It is an object of the invention to solve the problems of the prior art and to provide a surface inspection system which can be used in both the old and new production lines and can accurately inspect the surface quality of skin passed steel strips.
[0005] Another objective of the present invention is to develop the surface inspection system comprising a unique frame assembly for mounting illuminating devices and cameras of the surface inspection system.
[0006] It is further another objective of the present invention to provide the surface inspection system having frame assembly comprising a movable frame structure and fixed frame structure which reduces interference with activities such as strip threading operation, offline inspection, dent cleaning of bridle rolls, maintenance etc.

The motor (182) is energized to provide the necessary torque to rotate the first sprocket (186a). The first sprocket (186a) rotates the third sprocket (186c) via the second sprocket (186b). The third sprocket (186c), along with the fourth sprocket (186d) and the fifth sprocket (186e) drives on the second chain (184b), this facilitates movement of the plurality of rollers (190), thereby moving the movable frame structure (112) with respect to the fixed frame structure (108) from the parked position (P) to the work position (W) or vice versa. The movement of the movable frame structure (112) with respect to the fixed frame structure (108) from the parked position (P) to the work position (W) or vice versa is based on the direction of rotation of the motor (182).
[0046] Referring to Figures 1, 8 and 9, the top frame assembly (102) comprises a fixed frame structure (106) and a movable frame structure (110). The movable frame structure (110) is configured to be moved between a working position (W) (shown in Figure 9) and a parked position (P) (shown in Figure 8) with respect to the fixed frame structure (106). The fixed frame structure (106) and the movable frame structure (110) (as shown in Figures 8 to 11) comprises multiple frame members, bracket members and mounting members made of mild steel to accommodate various components of the surface inspection system (100). In the illustrated example, one configuration of the multiple frame members, bracket members and mounting members of the top frame assembly (102) is being depicted in the Figures 8 to 13. Alternatively, different configurations of the top frame assembly (102) may be possible, without limiting the scope of the invention.
[0047] The first illuminating device (120) is configured to irradiate the first surface (101a) is disposed on the movable frame structure (110). The first camera (130) and the second camera (132) are disposed on the fixed frame structure (106).

The movable frame structure (110) is moved in direction “D2” with respect to the fixed frame structure (106) to move the movable frame structure (110) from the working position (W) to the parked position (P). The movable frame structure (110) is moved with respect to the fixed frame structure (106) via a first drive mechanism (170).
[0048] Referring to Figures 10 to 15, the first drive mechanism (170) comprises a locking disc (171), at least one plumber block (172), a connecting shaft (175), at least one chain (174a, 174b), at least one sprocket (176a, 176b, 176c, 176d), at least one roller track (178a, 178b), and at least one rolling bracket (179a, 179b). In the illustrated example, the first drive mechanism (170) comprises four sprockets (176a, 176b, 176c, 176d) including a first sprocket (176a), a second sprocket (176b), a third sprocket (176c), and a fourth sprocket (176d). Alternatively, the first drive mechanism (170) may comprise one or more than one sprocket, without any limitations.
[0049] The third sprocket (176c) and the fourth sprocket (176d) are disposed on one side of the top frame assembly (102). The first sprocket (176a) and the second sprocket (176b) are disposed on the other side of the top frame assembly (102). The first sprocket (176a) is coupled to the second sprocket (176b) via a first chain (174a) of the at least one chain (174a, 174b). Ends of the first chain (174a) (as shown in Figure 12) are coupled to one end of a frame member (111) of the movable frame structure (110). More particularly, ends of the first chain (174a) (as shown in Figure 12) are coupled to at least one rolling bracket (179a) coupled to the frame member (111) of the movable frame structure (110). The first sprocket (176a) and the third sprocket (176c) are disposed on the connecting shaft (175). The connecting shaft (175) extends through the at least one plumber block (172). Rotation of any one of the first sprocket (176a) or the third sprocket (176c) causes a rotation in the other sprocket. The locking disc (171) is coupled to the end of the connecting shaft (175) next to the third sprocket (176c). The locking disc (171) comprises locking holes disposed along the circumference of the disc. A locking pin (not shown) of a disc locking frame (199) extending through one of locking hole locks the rotation of the locking disc (171).
[0050] The third sprocket (176c) is coupled to the fourth sprocket (176d) via a second chain (174b) of the at least one chain (174a, 174b). Ends of the second chain (174b) (as shown in Figure 13) are coupled to another end of the frame member (111) of the movable frame structure (110). More particularly, ends of the second chain (174b) (as shown in Figure 13) are coupled to at least one rolling bracket (179b) coupled to the frame member (111) of the movable frame structure (110).
[0051] Referring to Figures 10, 14, and 15, the movable frame structure (110) is supported by a plurality of rollers (165) disposed on the at least one rolling bracket (179a, 179b). The plurality of rollers (165) are configured to roll on the at least one roller track (178a, 178b) (as shown in Figures 14 and 15) to move the movable frame structure (110) with respect to the fixed frame structure (106).
[0052] During operation, i.e. when the movable frame structure (110) is to be moved with respect to the fixed frame structure (106) from the parked position (P) (as shown in Figure 8) to the working position (W) (as shown in Figure 9) or vice versa. The locking pin (not shown) extending through one of locking hole of the locking disc (171) is disengaged, thereby allowing the locking disc (171) to freely rotate. As the locking disc (171) is rotated, the third sprocket (176c) and the first sprocket (176a) also rotates, which in turn rotates the fourth sprocket (176d) and the second sprocket (176b) via the second chain (174b) and the first chain (174a) respectively. The first chain (174a) and the second chain (174b) pulls on the at least one rolling bracket (179a, 179b). The plurality of rollers (165) disposed on the at least one rolling bracket (179a, 179b) roll on the at least one roller track (178a, 178b), thereby moving the movable frame structure (110) with respect to the fixed frame structure (106). When the locking disc (171) is rotated in the counter-clockwise direction the movable frame structure (110) is moved to the working position (W), whereas when the locking disc (171) is rotated in the clockwise direction the movable frame structure (110) is moved to the parking position (P).
[0053] The top frame assembly (102) and the bottom frame assembly (104) comprises guards (160, 162) (shown in Figure 2 and 9) provided above the at least one illuminating device (120, 122) to avoid illuminating device (120, 122) breakage due to workpiece (103) breakage. The top frame assembly (102) and the bottom frame assembly (104) comprising the at least one illuminating device (120, 122) coupled to the movable frame structures (110, 112) are moved between the parking position (P) and the working position (W) provides the same accuracy as compared to market available fixed surface inspection systems.
[0054] The present invention relates to the surface inspection system (100) utilizes less space, investment and is very efficient since positioning plays an important role in defect detection. The disclosed surface inspection system (100) comprising the top frame assembly (102) and the bottom frame assembly (104) facilitates easy movement of the surface inspection system (100) between the working position and parking position, thereby reducing the down time during maintenance activities, thereby increasing productivity. The skin panel yield is improved, as the surface inspection system (100) facilitates faster and accurate decision. The movable and motorized frame assemblies of the surface inspection system (100) facilitate in the light cleaning activity, which will further enhance the detectability of defects. The disclosed surface inspection system (100) can be used in both the old and new production lines and can accurately inspect the surface quality of skin passed steel strips. The surface inspection system (100) having frame assemblies (102, 104) comprising the movable frame structure (110, 112) and the fixed frame structure (106, 108) reduces interference with activities such as strip threading operation, dent cleaning of bridle rolls, offline inspection etc.
