Description

Technical Field

[0001] The present invention relates to the technical field of detection marking, in particular to a pinhole detection marking device for electrolytic copper foil. Background Art

[0002] The reason for the pinholes in copper foil is that during online polishing, the friction between the polishing brush and the cathode roller will produce some impurities such as titanium oxide chips, silicon nitride particles, non-woven fabric fibers, resin powder, etc. These impurities enter the tank liquid with the polishing pure water. The overflow of the tank liquid will take away a part of it and enter the sewage tank for filtration and then enter the anode tank for electroplating. However, a part of it will still be deposited in the anode tank. During the electroplating process of the raw foil, pinholes (light-transmitting points) will be formed on the foil surface. The generation of pinholes is inevitable in electrolytic copper foil.

[0003] In the production of electrolytic copper foil, pinhole detection and marking are usually required to facilitate subsequent processing. However, during the detection and marking process, the electrolytic copper foil may jitter, and there may also be uneven areas on the electrolytic copper foil. At this time, it is difficult for light to pass through the electrolytic copper foil with pinholes, resulting in inaccurate detection results. In addition, the electrolytic copper foil may jitter and deviate during transmission, resulting in the mark position not matching the actual pinhole position. The inaccurate mark position causes great trouble to the subsequent electrolytic copper foil processing.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] In the prior art, during the process of winding the produced electrolytic copper foil, it is usually necessary to detect whether there are pinholes on the electrolytic copper foil. During the detection, the electrolytic copper foil is always being wound, and it is not possible to mark while inspecting. Then, the wound electrolytic copper foil needs to be re-inspected and processed in a darkroom later, which increases the workload of the staff. Therefore, this embodiment is specially invented to solve the above problem.

[0042] like Figures 1 to 3 As shown, this embodiment provides an electrolytic copper foil pinhole detection and marking device, including a winding mechanism 1 and a detection bracket 2, the detection bracket 2 spans the winding mechanism 1, and a support plate 3 is fixedly connected to the detection bracket 2. The detection marking mechanism 7 is arranged on the detection bracket 2, which is used to detect pinholes on the electrolytic copper foil and for marking.

[0043] The detection marking mechanism 7 includes multiple industrial cameras 701 fixedly connected to the detection bracket 2, a control module 702 is installed on the detection bracket 2, a marker 703 is slidably connected to the detection bracket 2, the industrial cameras 701 and the marker 703 are both electrically connected to the control module 702, and a matrix light source 8 is installed on the support plate 3 below the industrial camera 701, and the matrix light source 8 is used to irradiate the electrolytic copper foil.

[0044] In actual use, first, the detection bracket 2 is placed across the winding mechanism 1, and the winding mechanism 1 is an existing technology, and the specific structure and working state are no longer described in detail, so that the electrolytic copper foil is located on the upper side of the support plate 3, and the matrix light source 8 and multiple industrial cameras 701 can fully cover the width of the electrolytic copper foil, and in the process of the electrolytic copper foil being rolled up along the winding mechanism 1, the electrolytic copper foil passes through the matrix light source 8 in turn, so that the matrix light source 8 emits light to irradiate the electrolytic copper foil. When there is a pinhole on the electrolytic copper foil covered by the matrix light source 8, the light emitted by the matrix light source 8 passes through The pinhole on the electrolytic copper foil is emitted, and the industrial camera 701 captures the transmitted light and detects whether there is a pinhole in the electrolytic copper foil. At the same time, the industrial camera 701 transmits the pinhole detection signal to the control module 702, and the control module 702 analyzes the detection signal and transmits it to the marker 703. The sliding connection method between the marker 703 and the detection bracket 2 is both existing technology, and the specific structure is not repeated here, so that the marker 703 marks the position of the pinhole on the electrolytic copper foil, which is convenient for the staff to process the electrolytic copper foil with pinholes later.

[0045] To sum up, by setting up the detection bracket 2, industrial camera 701, matrix light source 8, marker 703 and control module 702, not only can the pinholes on the electrolytic copper foil be detected by the industrial camera 701 during the process of the winding mechanism 1 rolling up the electrolytic copper foil, but the parts where the pinholes exist can be marked by the marker 703. At the same time, it is convenient to detect and mark whether there are pinholes on the electrolytic copper foil, which makes it convenient for the staff to quickly find the electrolytic copper foil with pinholes later, thereby improving the work efficiency of the staff.

[0046] Example 2

[0047] During the detection process, the electrolytic copper foil shakes when the winding mechanism 1 rolls up the electrolytic copper foil, and there may also be uneven areas on the electrolytic copper foil. At this time, the light from the matrix light source 8 is not easy to pass through the electrolytic copper foil with pinholes, resulting in inaccurate detection results and easily causing defective electrolytic copper foil. Therefore, further improvements are made based on the above embodiment.

[0048] like Figures 4 to 7 As shown, the leveling mechanism 4 is arranged on the support plate 3, and the leveling mechanism 4 includes an adjusting plate 401 that is slidably connected to the support plate 3. Both ends of the adjusting plate 401 are slidably connected to clamping blocks 402 for leveling the electrolytic copper foil. The leveling mechanism 4 also includes a slide groove 403 provided on the support plate 3, and the adjusting plate 401 is slidably connected to the slide groove 403. A first elastic member 404 is provided between the slide groove 403 and the adjusting plate 401. A clamping groove 405 is provided on the clamping block 402, and the clamping groove 405 is used to clamp the electrolytic copper foil.

[0049] The power mechanism 5 is arranged on the side of the support plate 3 close to the winding mechanism 1. The power mechanism 5 includes two connecting blocks 501 fixedly connected to the support plate 3, and a transmission rod 502 is slidably connected between the two connecting blocks 501. When the transmission rod 502 slides longitudinally, it can drive the leveling mechanism 4 to slide horizontally. The power mechanism 5 includes an accommodating chamber 503 opened in the connecting block 501, and a piston rod 504 is slidably connected in the accommodating chamber 503. One end of the piston rod 504 close to the transmission rod 502 extends out of the accommodating chamber 503 and is fixedly connected to the transmission rod 502. A second elastic member 505 is set on the piston rod 504 and is located between the transmission rod 502 and the connecting block 501. The end of the accommodating chamber 503 away from the piston rod 504 is connected to an air guide pipe 506, and the free end of the air guide pipe 506 is connected to a guide cylinder 507 located in the support plate 3. A push rod 508 is slidably connected in the guide cylinder 507, and the free end of the push rod 508 is fixedly connected to the adjustment plate 401.

[0050] Elastic blocks 406 are fixedly connected to both vertical sides of the clamping groove 405 to increase the friction force on the electrolytic copper foil. A clearance groove 509 is opened on the connecting block 501, and both ends of the transmission rod 502 are located in the corresponding clearance groove 509. The volume of the accommodating cavity 503 is larger than the volume between the guide cylinder 507 and the push rod 508.

[0051] In actual use, first, the two sides of the electrolytic copper foil are inserted into the corresponding clamping grooves 405, and an elastic block 406 is provided in the clamping grooves 405, which can increase the friction between the electrolytic copper foil and the clamping grooves 405 through the elastic block 406. When the electrolytic copper foil is rolled up, the electrolytic copper foil will be constantly in a state of tension and relaxation. At this time, the electrolytic copper foil is prone to generating a shaking force, causing the electrolytic copper foil to drive the transmission rod 502 to slide upward along the yield groove 509, and the transmission rod 502 drives the piston rod 504 to slide upward along the connecting block 501. The second elastic member 505 is compressed, and the piston rod 504 pushes the gas in the accommodating chamber 503 into the guide cylinder 507 through the air guide tube 506. The volume of the accommodating chamber 503 is greater than the volume of the guide cylinder 507. After the gas in the accommodating chamber 503 is squeezed into the guide cylinder 507, the volume of the gas in the guide cylinder 507 increases rapidly, prompting the gas to drive the push rod 508 to slide rapidly along the guide cylinder 507.

[0052] At this time, the two push rods 508 drive the adjustment plate 401 to slide along the slide groove 403 in the opposite direction of the movement of the electrolytic copper foil, the first elastic member 404 is compressed, and the adjustment plate 401 drives the clamping block 402 to slide synchronously. At this time, the clamping block 402 drives the electrolytic copper foil to move in the opposite direction through the clamping groove 405 and the elastic block 406. Under the coordinated action of the winding mechanism 1 winding up the electrolytic copper foil, the clamping block 402 drives the electrolytic copper foil on the support plate 3 to be tightened and leveled through the clamping groove 405. During the process of tightening and leveling the electrolytic copper foil, the light emitted by the matrix light source 8 can accurately pass through the existing pinholes. At the same time, the industrial camera 701 can better capture the light passing through the pinholes, which is convenient for the industrial camera 701 to fully detect the pinholes on the electrolytic copper foil. When the electrolytic copper foil is in a relaxed state, the electrolytic copper foil does not The transmission rod 502 is squeezed again. At this time, under the action of the second elastic member 505, the second elastic member 505 drives the piston rod 504 to slide along the accommodating chamber 503 toward the transmission rod 502. The piston rod 504 sucks the gas in the guide cylinder 507 into the accommodating chamber 503 through the air guide tube 506. At this time, the gas pressure in the guide cylinder 507 decreases. Under the action of the first elastic member 404, the first elastic member 404 drives the adjustment plate 401 to slide in the direction of winding the electrolytic copper foil. At this time, the adjustment plate 401 drives the clamping block 402 to slide along the electrolytic copper foil, and the adjustment plate 401 drives the push rod 508 to slide along the guide cylinder 507. Subsequently, in the process of the winding mechanism 1 continuously winding the electrolytic copper foil, the above movement is repeated to continuously flatten the electrolytic copper foil, which is convenient for detecting and marking pinholes on the electrolytic copper foil.

[0053] In summary, through the arrangement of the transmission rod 502, the accommodating chamber 503, the piston rod 504, the adjusting plate 401 and the clamping block 402, not only can the shaking force generated when the electrolytic copper foil is rolled up be converted into the force of the adjusting plate 401 to drive the clamping block 402 to slide, thereby making the clamping block 402 move in the opposite direction to tighten and flatten the electrolytic copper foil, but also the shaking force is prevented from affecting the flatness of the electrolytic copper foil, ensuring that the matrix light source 8 can fully illuminate the electrolytic copper foil, avoiding the problem of pinholes not being detected, and realizing the power source for flattening the electrolytic copper foil by turning waste into treasure through the shaking force of the electrolytic copper foil, which not only reduces energy consumption, but also improves the effect and efficiency of the detection mark of the electrolytic copper foil, and facilitates better production of good electrolytic copper foil.

[0054] Example 3

[0055] During the use of the above embodiment, it was also found that the shaking force generated during the winding of the electrolytic copper foil can easily cause the electrolytic copper foil to shift on the support plate 3. At this time, when marking the detected pinholes, it is easy to mark the position of the pinholes inaccurately. Therefore, further improvements are made to the above embodiment.

[0056] like Figures 5 to 9 As shown, the correction mechanism 6 is arranged in the adjustment plate 401. When one clamping block 402 slides, the correction mechanism 6 can drive the other clamping block 402 to slide, which is used to assist in correcting the offset of the electrolytic copper foil. The correction mechanism 6 includes a placement groove 601 opened in the adjustment plate 401, and a correction plate 602 is slidably connected in the placement groove 601. The side of the clamping block 402 close to the placement groove 601 is fixedly connected to a push block 604 located in the placement groove 601 through a positioning column 603. The positioning column 603 is slidably connected to the adjustment plate 401, and both ends of the correction plate 602 can contact the corresponding push blocks 604.

[0057] A third elastic member 605 is connected between the side of the correction plate 602 close to the clamping block 402 and the placement groove 601, and a fourth elastic member 606 is connected between the clamping block 402 and the adjustment plate 401. The elastic force of the third elastic member 605 is equal to the sum of the elastic forces of the two fourth elastic members 606, and the opposite surfaces of the two push blocks 604 are both inclined surfaces.

[0058] In actual use, when the electrolytic copper foil moves and deviates on the support plate 3, when the adjustment plate 401 slides, one side of the electrolytic copper foil contacts the side wall of the clamping groove 405 on the corresponding clamping block 402. At this time, one side of the electrolytic copper foil pushes the clamping block 402 to slide outward along the adjustment plate 401. The clamping block 402 drives a push block 604 through the positioning column 603 and no longer contacts the correction plate 602. The fourth elastic member 606 is compressed, and one of the clamping blocks 402 slides, and the balance between the third elastic member 605 and the fourth elastic member 606 is Destruction, under the action of the third elastic member 605, the third elastic member 605 drives the correction plate 602 to slide along the placement groove 601, so that the correction plate 602 pushes the other push block 604 to slide outward along the adjustment plate 401, and at this time, the other push block 604 drives the other clamping block 402 to slide outward through the positioning column 603, so that the other clamping block 402 drives the other side of the electrolytic copper foil to move outward through the clamping groove 405 and the elastic block 406, thereby correcting the offset of the electrolytic copper foil, making it easier for the marker 703 to accurately mark the pinholes on the electrolytic copper foil.

[0059] After the offset position of the electrolytic copper foil is corrected, under the action of the third elastic member 605, the third elastic member 605 drives the clamping block 402 to slide inward along the adjustment plate 401 to the initial position. At this time, the two clamping blocks 402 drive the two push blocks 604 to slide relative to each other through the positioning column 603. The two push blocks 604 drive the correction plate 602 to return to the equilibrium state again through the inclined surface. When one of the clamping blocks 402 is squeezed by the electrolytic copper foil, the above movement is repeated to correct the offset of the electrolytic copper foil, which is convenient for accurately marking the position of the pinhole.

[0060] In summary, by arranging the correction plate 602, the push block 604, the positioning column 603, the third elastic member 605 and the fourth elastic member 606, not only can the offset electrolytic copper foil be corrected by the correction plate 602 and the push block 604 during the sliding process of the adjustment plate 401, thereby ensuring that the electrolytic copper foil is in a normal detection state, but also it is convenient for the marker 703 to mark the pinholes on the electrolytic copper foil, thereby improving the accuracy of the marking, and at the same time it is convenient for the staff to process the pinholes, thereby improving the work efficiency of the staff.
