Description

Technical Field

[0001] This invention relates to the field of electrolytic copper foil production technology, and in particular to a copper foil edge collapse detection device and method. Background Technology

[0002] Electrolytic copper foil is an important material in the manufacture of copper clad laminates (CCL), printed circuit boards (PCB), and lithium-ion batteries.

[0003] The copper foil production machine is used for the production of electrolytic copper foil. In the production of electrolytic copper foil, copper foil is first formed on the surface of the cathode roller. After being peeled off, it enters the anti-oxidation tank through the roller system for chromium plating. Then, it passes through the liquid roller, the acid extrusion roller, and is subsequently dried, flattened, and rolled into a copper foil master roll for the next processing step. Finally, it is cut into the size required by the customer in the slitting workshop. During the slitting process, due to differences in equipment and operation, some copper foil may have defects, such as collapsed edges. Existing methods cannot effectively detect collapsed edges of copper foil, thus affecting the yield of copper foil. Summary of the Invention

[0004] In view of the above situation, it is necessary to provide a copper foil edge collapse detection device and method to address the problem of copper foil edge collapse detection in the prior art.

[0005] A copper foil edge collapse detection device includes two support assemblies, a detection platform assembly, and a control assembly. The two support assemblies are arranged opposite to each other and are used to wind up copper foil. The detection platform assembly is located between the two support assemblies. The detection platform assembly includes a base, two transparent scale plates, two detection mechanisms, and two connecting mechanisms. The two transparent scale plates are located at opposite ends of the base, and the two connecting mechanisms are connected to opposite side edges of the base. Each detection mechanism includes an image acquisition device. The two image acquisition devices are respectively located on the two connecting mechanisms and adjacent to the corresponding transparent scale plates. The control assembly is located on one side of the base and is electrically connected to the image acquisition devices.

[0006] The beneficial effects of this invention are:

[0007] Copper foil is wound onto a support assembly, and one end of the copper foil is placed on another support assembly so that the copper foil is gradually wound onto the other support assembly. According to the thickness of the copper foil, the connecting mechanism is adjusted so that the image acquisition device is oriented towards the center of the copper foil thickness. The image acquisition device is activated, and as the copper foil passes through the image acquisition device, the image acquisition device continuously acquires images of the side of the copper foil through a transparent scale plate. The control assembly analyzes the acquired images of the side of the copper foil to detect copper foil edge collapse. Then, the other support assembly completes the winding of the copper foil. This invention can effectively detect copper foil edge collapse.

[0008] Furthermore, the connecting mechanism includes two fixed rods and two connecting rod units. One end of the fixed rod is connected to the side edge of the base, and the other end of the fixed rod is connected to the connecting rod unit.

[0009] Furthermore, the connecting rod unit includes a first connecting rod, a second connecting rod, and a first knob. The second connecting rod is sleeved inside the first connecting rod. The first knob is located at one end of the first connecting rod and is threadedly connected to the first connecting rod. One end of the first knob passes through the first connecting rod and abuts against the second connecting rod. One end of the first connecting rod is connected to the fixed rod. The image acquisition device is disposed on the second connecting rod.

[0010] Furthermore, the detection mechanism also includes a warning light, which is located at the top of the second connecting rod.

[0011] Furthermore, the detection platform assembly also includes a base and several rollers. The base is disposed on the pedestal and located between the two transparent scale plates. Several rollers are spaced apart on the base and are movably connected to the base. A first motor is provided on one side of the base and is electrically connected to the several rollers.

[0012] Furthermore, the control component includes an industrial computer body and a display panel. The display panel is disposed on the industrial computer body and is used to display and set parameters. The industrial computer body is electrically connected to the image acquisition device and is used to store and process the acquired images.

[0013] Furthermore, the bracket assembly includes a bracket, a fixing frame, a slot, a reel, and a second motor. The reel is fixed to the bracket via the slot. Both ends of the reel are provided with fixing plates, which are connected to the bracket. The second motor is provided on the side of one fixing plate facing away from the reel and is connected to the reel. The fixing frame is provided on both sides of the slot and is connected to the bracket.

[0014] Furthermore, the lower end of the bracket is provided with several rollers, and one side of each roller is provided with a wheel buckle.

[0015] The present invention also provides a method for detecting copper foil edge collapse, applied to the aforementioned copper foil edge collapse detection device, the method comprising the following steps:

[0016] The desired thickness of the copper foil is set by a control component located on one side of the base, and two image acquisition devices fixed to the connecting mechanism are activated.

[0017] The copper foil is wound onto one of its support components, and one end of the copper foil is placed on another support component so that the copper foil is gradually wound onto the other support component.

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

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

[0027] Specifically, the testing platform assembly 2 is located between the two supports 11. The testing platform assembly 2 includes a base 21, two transparent scale plates 22, two testing mechanisms 23, and two connecting mechanisms 24. The two transparent scale plates 22 are located at opposite ends of the base 21. The connecting mechanism 24 includes a fixing rod 241 and a connecting rod unit 242. One end of the fixing 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 inside the first connecting rod 2421. The first knob 2423 is located at one end of the first connecting rod 2421 and is threadedly connected to the first connecting rod 2421. One end of the first knob 2423 passes through the first connecting rod 2421 and abuts against the second connecting rod 2422. One end of the first connecting rod 2421 is connected to the fixed rod 241. The detection mechanism 23 includes an image acquisition device 231 and a warning light 232. The image acquisition device 231 is mounted on the second connecting rod 2422 and is located on opposite sides of the base 21, adjacent to the corresponding transparent scale plate. 22. A warning light 232 is located on the top of the second connecting rod 2422. The warning light 232 is used to emit a flashing light. The detection platform assembly 2 also includes a base 25 and multiple rollers 26. The base 25 is located on the base 21 between two transparent scale plates 22. Multiple rollers 26 are spaced apart on the base 25 and are movably connected to the base 25. A first motor (not shown) is located on one side of the base 25. The first motor is electrically connected to the multiple rollers 26. The copper foil moves from the roll 14 onto the rollers 26. It should be noted that the width of the rollers 26 is smaller than the width of the copper foil. This ensures that a small portion of the copper foil's width is positioned outside the roller 26, guaranteeing the movement of the copper foil. Simultaneously, the image acquisition device 231 captures 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 using the first knob 2423, thereby achieving height adjustment of the image acquisition device 231 and keeping it aligned with the centerline of the copper foil. When the height difference between the highest and lowest points of the side of the copper foil exceeds the allowable range, the warning light 232 begins to flash to alert the staff.

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

[0029] The present invention also provides a method for detecting copper foil edge collapse, applied to the aforementioned copper foil edge collapse detection device, the method comprising the following steps:

[0030] The desired thickness of the copper foil is set by the display panel 32 located on one side of the base 21, and the two image acquisition devices 231 on the first motor, the second motor and the second connecting rod 2422 are started.

[0031] The copper foil is wound onto the spool 14 of one of the support components 1, and one end of the copper foil is placed on the spool 14 of the other support component 1. The copper foil is driven by the second motor to rotate the spool 14 so that the copper foil is gradually wound onto the spool 14 of the other support component 1. When the copper foil passes through the acquisition range of the two image acquisition devices 231, the two image acquisition devices 231 respectively acquire images of the opposite sides of the copper foil through the corresponding transparent scale plates 22 to obtain the acquired images.

[0032] The acquired images are transmitted to the industrial control computer 31, which processes and analyzes the height difference between the highest and lowest points of the opposite sides of the copper foil.

[0033] If the height difference exceeds the allowable range, warning light 232 will start flashing to remind the staff. At this time, the first motor and the second motor will stop working. After the staff confirms, the first motor and the second motor will continue to work.

[0034] The copper foil is wound onto the spool 14 of another support assembly 1.

[0035] In this invention, copper foil is wound onto a spool 14 of one support assembly 1, and one end of the copper foil is placed on a spool 14 of another support assembly 1. The copper foil is driven by a second motor to rotate the spool 14, so that the copper foil is gradually wound onto the spool 14 of the other support assembly 1. The height of the second connecting rod 2422 is adjusted according to the thickness of the copper foil so that the image acquisition device 231 is oriented towards the center of the copper foil thickness. The image acquisition device 231 is then activated. As the copper foil passes the image acquisition device 231, the two image acquisition devices 231 respectively acquire images of the opposite sides of the copper foil through corresponding transparent scale plates 22. Using the scale of the transparent scale plate 22 as a reference, the industrial control computer body 31 controls the copper foil. The images acquired from the opposite side are analyzed to find the corresponding scales on the transparent scale plate 22 for the highest and lowest points on the side of the copper foil. It is then determined whether the height difference between the highest and lowest points is within the allowable range, thus indicating whether the copper foil has collapsed. A warning light 232 flashes to indicate this. It should be noted that because the two image acquisition devices 231 work simultaneously, if the height difference between the highest and lowest points of the copper foil on either side exceeds the allowable range, the warning light 232 will still flash to indicate this. After confirmation by the staff, the copper foil is then wound up by the roller 14 of the other support assembly 1. The entire inspection process can improve the screening of copper foil that has collapsed and enhance the effectiveness of quality inspection.
