[0025] A copper foil edge collapse detection device, such as Figure 1 and Figure 2 As shown, it includes two bracket components 1, a detection platform component 2 and a control component 3.

[0026] Specifically, two bracket assemblies 1 are arranged opposite to each other, one of which is used to place copper foil, and the other bracket assembly 2 is used to roll up copper foil. The bracket assembly 1 includes a bracket 11, a fixing frame 12, a card slot 13, a reel 14 and a second motor (not shown). The reel 14 is fixed to the bracket 11 through the card slot 13. Both ends of the reel 14 are provided with fixing plates 15, and the fixing plates 15 are connected to the bracket 11. A second motor is provided on a side of the fixing plate 15 facing away from the reel 14, and the second motor is connected to the reel 14. Both sides of the card slot 13 are provided with fixing frames 12. The fixing frame 12 is connected to the bracket 11, and a plurality of rollers 16 are provided at the lower end of the bracket 11. A wheel buckle 161 is provided on one side of the roller 16. The two brackets 11 are moved to the two ends of the base 21 respectively through the rollers 16, and the distance between the bracket 11 and the base 21 is adjusted. Then, the roller 16 is locked through the wheel buckle 161. The copper foil is placed on the reel 14, and the second motor drives the reel 14 to rotate on the card slot 13, so that the copper foil on the reel 14 can rotate together. The bracket 11 and the fixing frame 12 ensure the support and relative fixation of the copper foil on the reel 14.

[0027] Specifically, the detection platform assembly 2 is arranged between the two brackets 11, and the detection platform assembly 2 includes a base 21, two transparent scale plates 22, two detection mechanisms 23 and two connecting mechanisms 24. The two transparent scale plates 22 are arranged at opposite ends of the base 21. The connecting mechanism 24 includes a fixed rod 241 and a connecting rod unit 242. One end of the fixed rod 241 is connected to the side edge of the base 21. The connecting rod unit 242 includes a first connecting rod 2421, a second connecting rod 2422 and a first knob 2423. The second connecting rod 2422 is sleeved in the first connecting rod 2421. The first knob 2423 is disposed at one end of the first connecting rod 2421, the first knob 2423 is threadedly connected to the first connecting rod 2421, one end of the first knob 2423 passes through the first connecting rod 2421, and is abutted against the second connecting rod 2422, one end of the first connecting rod 2421 is connected to the fixing rod 241, the detection mechanism 23 includes an image collector 231 and a warning light 232, the second connecting rod 2422 is provided with an image collector 231, the image collector 231 is located on the opposite side edges of the base 21, and is adjacent to the corresponding transparent scale plate 22, a warning light 232 is arranged on the top of the second connecting rod 2422, and the warning light 232 is used to emit a flashing light. The detection platform assembly 2 also includes a base 25 and a plurality of rollers 26. The base 25 is arranged on the base 21 and is located between the two transparent scale plates 22. A plurality of rollers 26 are arranged on the base 25 at intervals and are movably connected to the base 25. A first motor (not shown) is arranged on one side of the base 25, and the first motor is electrically connected to the plurality of rollers 26. The copper foil moves from the reel 14 to the rollers 26. It should be noted that the width of the rollers 26 is smaller than the width of the copper foil. A small part of the copper foil in the width direction is placed outside the roller 26, so that the movement of the copper foil can be ensured. At the same time, the image collector 231 is used to collect the side image of the copper foil through the transparent scale plate 22. For copper foils of different thicknesses, the height of the second connecting rod 2422 can be adjusted and fixed by the first knob 2423, so as to achieve the height adjustment of the image collector 231 and keep the image collector 231 aligned with the center line of the copper foil. When the height difference between the highest point and the lowest point on the side of the copper foil exceeds the allowable range, the warning light 232 starts to flash to remind the staff.

[0028] Specifically, the control component 3 is arranged on one side of the base 21, and the control component 3 includes an industrial computer body 31 and a display panel 32. The display panel 32 is arranged on the industrial computer body 31, and the display panel 32 is used to display and set parameters. The industrial computer body 31 is electrically connected to the image acquisition device 231, and the industrial computer body 31 is used to store and analyze the acquired images.

[0029] The present invention also provides a copper foil edge collapse detection method, which is applied to the above-mentioned copper foil edge collapse detection device. The copper foil edge collapse detection method comprises the following steps:

[0030] The expected thickness of the copper foil is set by the display panel 32 disposed on one side of the base 21, and the first motor, the second motor and the two image collectors 231 on the second connecting rod 2422 are started;

[0031] The copper foil is rolled up on the reel 14 of one support assembly 1, and one end of the copper foil is placed on the reel 14 of the other support assembly 1. The copper foil is driven by the second motor to rotate the reel 14 so that the copper foil is gradually rolled up on the reel 14 of the other support assembly 1. When the copper foil passes through the acquisition range of the two image collectors 231, the two image collectors 231 respectively collect images of the opposite sides of the copper foil through the corresponding transparent scale plates 22 to obtain the collected images;

[0032] The collected image is transmitted to the industrial control computer body 31, and the industrial control computer body 31 performs data processing and analysis on the height difference between the highest point and the lowest point of the opposite side of the copper foil;

[0033] If the height difference exceeds the allowable range, the warning light 232 starts flashing to remind the staff, at which time the first motor and the second motor stop working. After the staff confirms, the first motor and the second motor continue to work;

[0034] The copper foil is rolled up on the reel 14 of another support assembly 1 .

[0035] In the present invention, the copper foil is rolled up on the reel 14 of one support assembly 1, and one end of the copper foil is placed on the reel 14 of the other support assembly 1. The copper foil is driven by the second motor to rotate the reel 14, so that the copper foil is gradually rolled up on the reel 14 of the other support assembly 1. According to the thickness of the copper foil, the height of the second connecting rod 2422 is adjusted so that the image collector 231 faces the center position of the thickness of the copper foil, and the image collector 231 is started. When the copper foil passes through the image collector 231, the two image collectors 231 respectively collect images of the opposite sides of the copper foil through the corresponding transparent scale plate 22. With the scale of the transparent scale plate 22 as a reference, the industrial computer body 31 measures the copper foil. The images collected from the opposite sides are analyzed to find out the corresponding scales of the highest point and the lowest point on the side of the copper foil on the transparent scale plate 22, and to judge whether the height difference between the highest point and the lowest point is within the allowable range. It is thus concluded whether the copper foil has collapsed, and a prompt is given by flashing the warning light 232. It should be noted that because the two image collectors 231 work at the same time, if the height difference between the highest point and the lowest point of the copper foil on either side exceeds the allowable range, the warning light 232 will still flash to give a prompt. After confirmation by the staff, the reel 14 of the other bracket assembly 1 completes the winding of the copper foil. The entire detection process can improve the screening of collapsed copper foil and enhance the effectiveness of quality inspection.
