[0026] The utility model provides a CCD appearance detection device for a die-cutting machine, which is used to improve the quality of pole pieces, detect whether the pole pieces meet the standards of appearance requirements, and reduce the impact on subsequent processing.

[0027] like Figures 1 to 5 As shown, a preferred embodiment of the CCD appearance detection device of the die-cutting machine of the present invention includes a substrate 1, and a pole piece front side defect detection mechanism 12, a backlight detection mechanism 3, a first back side defect detection mechanism 4 and a second back side defect detection mechanism 5 with the same structure are arranged on the substrate 1 along the running path of the pole piece 17. The angles of the pole piece front side defect detection mechanism 12, the backlight detection mechanism 3, the first back side defect detection mechanism 4 and the second back side defect detection mechanism 5 are adjustable to perform multi-directional detection of the pole piece 17.

[0028] In this embodiment, the angles of the electrode front defect detection mechanism 12, the backlight detection mechanism 3, the first back defect detection mechanism 4 and the second back defect detection mechanism 5 are adjustable, so that the electrode 17 can be photographed from multiple directions and angles, thereby improving the appearance inspection quality of the electrode 17.

[0029] In this embodiment, the electrode front defect detection mechanism 12 includes a camera bracket 6 and a light source bracket 7. One end of the camera bracket 6 can be rotatably adjusted and set on the substrate 1, and the other end of the camera bracket 6 is set with a CCD camera module 8. The camera bracket 6 can adjust the optimal angle of the CCD camera module 8 for taking pictures to ensure the quality of the pictures.

[0030] The CCD camera module 8 includes a protective cover, a light source lens arranged in the protective cover, and an independent cooling fan. The protective cover can prevent interference from the external dust environment and improve the stability of taking pictures.

[0031] The light source bracket 7 includes a base and a rotating mounting plate 9. The base is fixedly mounted on the substrate 1. The rotating mounting plate 9 is adjustable on the base. One end of the rotating mounting plate 9 is provided with a light source 18 facing the CCD camera module 8.

[0032] The end of the rotatable mounting plate 9 near the base is provided with an arc-shaped adjustment hole 10. During use, the rotatable mounting plate 9 can be connected to the base by screws passing through the arc-shaped adjustment hole 10. By adjusting the angle of the arc-shaped adjustment hole 10, the angle of the rotatable mounting plate 9 can be adjusted accordingly, so that the light source 18 can face the CCD camera module 8 directly to capture and detect the pole piece 17, thereby improving the light source utilization rate of the CCD camera module 8, thereby improving the quality of the captured images and improving the quality of the detection of the pole piece 17.

[0033] In this embodiment, the middle part of the rotating mounting plate 9 is laterally provided with an air blowing pipe 11 facing the CCD camera module 8. The air blowing pipe 11 blows compressed air towards the light source lens of the CCD camera module 8 to ensure the clarity of the light source lens.

[0034] In this embodiment, the backlight detection mechanism 3 also includes a belt pressing seat 12 and a belt pressing fixing seat 13 which are relatively arranged on the substrate 1. A guide plate 14 is provided at the bottom of the belt pressing seat 12 and the belt pressing fixing seat 13.

A cylinder 15 connected to the mounting seat is provided on one side of the belt pressing fixed seat 13, and the guide piece 14 of the belt pressing fixed seat 13 can be driven to move back and forth by the cylinder 15, thereby adjusting the distance between the guide piece 14 at the bottom of the belt pressing fixed seat 13 and the guide piece 14 at the bottom of the belt pressing seat 12.

[0036] When the guide piece 14 at the bottom of the belt pressing seat 13 and the guide piece 14 at the bottom of the belt pressing seat 12 press the pole piece 17 passing through them, they can provide a guiding effect on the pole piece 17 and the stability of the pole piece 17 when taking pictures. When the guide piece 14 at the bottom of the belt pressing seat 13 retracts, it is convenient to pass through the pole piece 17.

[0037] A slit for light transmission is disposed transversely on the guide plate 14 , and a light source 18 and a camera are distributed on both sides of the slit to form a backlight photography mode, thereby realizing the functions of perforation and related defect and size detection.

[0038] In this embodiment, a die-cutting mechanism (not shown in the figure) for cutting the electrode 17 is also provided on the substrate 1. The die-cutting mechanism is used to die-cut the electrode 17 from the middle. The first back-side defect detection mechanism 4 and the second back-side defect detection mechanism 5 are respectively arranged on the upper and lower sides of the die-cutting mechanism, and are respectively used to take pictures and detect the die-cut electrode 17.
