Description

Technical Field

[0001] This invention relates to the field of cathode plate inspection technology, and more specifically to a cathode plate appearance quality inspection device. Background Technology

[0002] Modern copper electrolysis production processes generally employ the PC electrolysis method, equipped with advanced automated mechanical units. The deposited cathode copper (unpeeled cathode copper plates) is transported from the electrolytic cell to the cathode stripping unit by a dedicated automated electrolysis crane. After washing, pre-peeling, and peeling processes, qualified cathode copper plates (usually made of permanent stainless steel) are stacked by the cathode stripping unit and returned to the electrolytic cell for continued production. The peeled cathode copper sheets are then stacked and enter the next production process.

[0003] However, under the long-term exposure to impurities in the electrolyte and electrochemical reactions, existing cathode copper motherboards will have impurities deposited on their surface, resulting in oxidation defects such as dark gray stains / surfaces. This reduces the adhesion of the cathode copper motherboard, causing the cathode copper adhering to the board surface to fall off prematurely into the electrolytic cell, thus resulting in certain defects on the surface of the cathode copper board. Due to the high requirements of the market for the surface quality of cathode copper, unqualified cathode copper sheets need to be removed before stacking and packaging. Qualified cathode copper sheets can only be put into the market after being stacked, packaged, and labeled. Currently, they are all sorted manually. Relying solely on manual inspection and sorting will result in poor sorting effect, high labor intensity, and low efficiency. Summary of the Invention

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0033] Reference Figures 1-8 As shown, a cathode plate appearance quality inspection device includes a conveying mechanism 1, on which two sets of image acquisition devices 2 are installed, and further includes:

[0034] The transfer mechanism 3 is set on the conveying mechanism 1 and is used to transport the cathode copper plate from one end of the conveying mechanism 1 to the other end. During the journey, two sets of image acquisition devices 2 acquire images of both sides of the cathode copper plate to check for defects.

[0035] The marking component 6 is located on the top of the transfer mechanism 3. After a defect is identified, the defective part of the cathode copper plate can be marked by the marking component 6 to facilitate subsequent repair.

[0036] The feeding mechanism 4 is located at one end of the conveying mechanism 1. It is used to store the cathode copper plates and can place the cathode copper plates one by one, so that the transfer mechanism 3 can transfer them one by one.

[0037] The material sorting rack 5 is located at the other end of the conveying mechanism 1. The material sorting rack 5 is equipped with a first material sorting platform 51 and a second material sorting platform 52. The first material sorting platform 51 is used to place qualified cathode copper plates, while the second material sorting platform 52 is used to place defective cathode copper plates.

[0038] In one embodiment, the transfer mechanism 3 includes a support platform 31. A guide wheel 32 is provided on one side of the support platform 31 and is movably connected to the transfer mechanism 1. The side wall of the transfer mechanism 1 is provided with a guide groove that cooperates with the guide wheel 32. A first telescopic rod 33 is fixedly provided on the top of the support platform 31. A clamping component 34 is provided on the movable end of the first telescopic rod 33. A marking component 6 is movably provided on the top of the clamping component 34.

[0039] After the cathode copper plate is lowered by the feeding mechanism 4, it is first clamped on both sides of the copper plate by the clamping assembly 34. The guide wheel 32 drives the copper plate to move forward. When it passes the first image acquisition device 2, the upper surface of the copper plate is imaged to determine whether there are any defects. If there are, the defect can be marked by the marking assembly 6.

[0040] In one embodiment, the clamping assembly 34 includes a backing plate 341, a bidirectional threaded rod 342 is rotatably disposed inside the backing plate 341, clamping plates 343 are sleeved at both ends of the bidirectional threaded rod 342, and a transverse moving assembly fixed to the first telescopic rod 33 is also disposed on one side of the backing plate 341, and a marking assembly 6 is disposed on the transverse moving assembly.

[0041] The lateral movement assembly includes a bracket 344 fixed to the first telescopic rod 33, a first lead screw 3441 rotatably disposed inside the bracket 344, a movable frame 345 sleeved on the first lead screw 3441, a marking assembly 6 disposed on the movable frame 345, a first drive shaft 346 rotatably disposed on one side of the movable frame 345, and a backing plate 341 rotatably connected to the movable frame 345 through the first drive shaft 346;

[0042] First, move the two clamping components 34 to both sides of the copper plate, then open the clamping plate 343 to allow the copper plate to extend into the clamping plate 343 and fix the copper plate in place. Finally, the copper plate can be moved from one end to the other along the conveying mechanism 1 through the clamping components 34.

[0043] In one embodiment, the marking assembly 6 includes a first crossbeam 61 fixed to a movable frame 345, a second lead screw 611 rotatably disposed inside the first crossbeam 61, a second crossbeam 62 disposed at the top of the first crossbeam 61, a first movable block 63 sleeved on the second lead screw 611 disposed at the bottom of the second crossbeam 62, a second drive shaft 64 disposed between the second crossbeam 62 and the first movable block 63, a third lead screw 621 rotatably disposed inside the second crossbeam 62, a second movable block 65 sleeved on the third lead screw 621, a second telescopic rod 66 disposed on the second movable block 65, a turntable 67 rotatably disposed at the movable end of the second telescopic rod 66, and a marking pen 68 disposed on the turntable 67;

[0044] When the copper plate passes the first image acquisition device 2, image information of one side of the copper plate can be acquired. The appearance of the cathode copper is marked by image processing. In the Unity3D digital twin environment, the appearance of the cathode copper can be automatically analyzed and detected to see if there are any defects. The type and coordinate position of the defects are automatically identified and then sent to the marking component 6. On the marking component 6, the second crossbeam 62 is rotated by the second drive shaft 64 to make it perpendicular to the first crossbeam 61. Then, the marking pen 68 is moved to the top of the defect by the rotation of the second lead screw 611 and the third lead screw 621. Finally, the marking pen 68 marks the defect by the downward movement of the second telescopic rod 66. Then, the copper plate continues to move forward and is flipped by the first drive shaft 346 during the movement. The other side is then inspected by the second image acquisition device 2.

[0045] In one embodiment, the feeding mechanism 4 includes a slide 41 located within the conveying mechanism 1. The width of the slide 41 is smaller than that of the copper plate. The two sides of the copper plate are located outside the slide 41. A frame 42 is provided on the slide 41. A feeding mechanism 43 is provided on the frame 42. A buffer mechanism 44 is provided at the bottom of the feeding mechanism 43. A hydraulic push plate 45 is provided at the bottom of the frame 42.

[0046] The feeding mechanism 43 can ensure that one cathode copper plate is placed at a time. When the cathode copper plate falls, it can be slowly placed on the slide table 41 by the buffer mechanism 44. Then, the copper plate is pushed forward by the hydraulic push plate 45 and directly pushed into the conveying mechanism 1, which is convenient for the transfer mechanism 3 to hold.

[0047] In one embodiment, the feeding mechanism 43 includes a fixed frame fixed to the frame 42. A frame 431 is provided inside the fixed frame. A third drive shaft 432 rotatably connected to the fixed frame is provided at the middle of both ends of the frame 431. A first clamp 433 and a second clamp 434 are slidably provided inside the frame 431. The structure of the second clamp 434 is the same as that of the first clamp 433. The movable ends of the first clamp 433 and the second clamp 434 are located inside the frame 42. The second clamp 434 is used to clamp the bottommost cathode copper plate, while the first clamp 433 is used to clamp the copper plates above the second to last layer.

[0048] Since the frame 431 uses a lever-based movement method, the two clamps can maintain opposite movements. When the first clamp 433 is released, the second clamp 434 will support the bottom cathode copper plate inward. At this time, the first clamp 433 moves inward and clamps the second-to-last copper plate. Simultaneously, the second clamp 434 will open, allowing the bottom copper plate to fall downward. By repeating this process, the copper plates can fall one by one.

[0049] In one embodiment, the first clamp 433 includes a lifting block 4331 located within the frame 431. The lifting block 4331 has movable sliders 4335 slidably connected to the frame 431 on both sides. A rotating block 4332 is rotatably mounted on the lifting block 4331. A hydraulic rod 4333 is mounted on the rotating block 4332, which has a certain elasticity. This is mainly to ensure that when one clamp is not in position, the other clamp will not lose its clamping force, thus preventing all the copper plates from falling directly. A pressing plate 4334 is provided at the end of the hydraulic rod 4333 away from the rotating block 4332.

[0050] In one embodiment, the buffer mechanism 44 includes a mounting plate 441 fixed to the bottom of the frame 42, a guide rod 442 is provided inside the mounting plate 441, a limiting slider 444 is sleeved on the guide rod 442, a return spring 443 sleeved on the guide rod 442 is provided between the limiting slider 444 and the bottom of the mounting plate 441, and a buffer plate 445 located at the bottom of the second clamp 434 is provided on the limiting slider 444.

[0051] After the copper plate falls, it will first land on the buffer plate 445. Then, under the weight of the copper plate, the buffer plate 445 will gradually fall until the copper plate lands on the slide table 41, which has a certain buffering effect and prevents the copper plate from hitting the slide table 41.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
