[0002] Alkali polishing is usually a process of using an alkaline solution for cleaning or treatment in chemical processing. Alkali polishing is a common material treatment step, which is particularly important in applications that require a highly pure and clean surface.

[0003] The utility model with the publication number CN218182239U discloses a slow lifting device. The key points of its technical solution are as follows: It includes a slow lifting inner tank, and the slow lifting inner tank includes a tank body, a first tank cover and a second tank cover. The first tank cover and the second tank cover are respectively rotatably installed on both sides of the opening of the tank body. The first tank cover and the second tank cover can cooperate with the tank body to make the tank body in an open or closed state. When the tank body is in the closed state, the first tank cover and the second tank cover are respectively inclined downward towards each other. When the water vapor in the slow lifting inner tank rises, it is blocked by the first tank cover and the second tank cover and condenses into distilled water. The distilled water will flow down along the first tank cover and the second tank cover to the closing place of the two tank covers and flow back into the tank body for reuse. It can reduce the evaporation loss of part of the water, reduce the water consumption of the slow lifting process, save production costs, and does not affect the cleaning effect of the battery wafers.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0032] In an embodiment of the present utility model, please refer to Figure 2 And Figure 3, the adjusting device 2 includes two motors 21. Both of the two motors 21 are fixedly connected to the support plate 1. The output end of the motor 21 is fixedly connected with a rotating rod 22. Two wire reels 23 are fixedly connected to the arc surface of the rotating rod 22. A connecting wire 24 is fixedly connected to the arc surface of the wire reel 23. The connecting wire 24 slidably penetrates through the inner wall of the support plate 1. The same contact plate 25 is installed at one end of the two connecting wires 24 away from the wire reel 23. An elastic plate 26 is fixedly connected to the side of the contact plate 25 close to the connecting wire 24. During the backside alkaline polishing process of the battery, the lifting plate 5 can be driven by the power device 4 to slowly lift the two battery wafers. Through the pure hydrochloric acid in the acid tank, the metal ions and alkali residues remaining from the previous functional tank can be removed. However, only by using the power device 4 on the support plate 1 and cooperating with the lifting plate 5 to lift the battery wafers, the battery wafers will tilt to both sides, and there is also a risk of the flower basket of the robotic arm falling off. Moreover, the polished surface tooth position contact is liquid-carrying, and there are many water pattern marks, which affect the efficiency and yield of the production line. At this time, the adjusting device 2 can be used to lift both sides of the battery, so as to reduce the impact of accumulated water and liquid-carrying on the natural oxide layer of the polished surface of the battery wafer by lifting both sides of the battery, avoid batch rework of the battery wafers, improve the liquid-carrying of the polished surface tooth position contact, reduce the output of water pattern marks, and improve the production efficiency. A connecting rod 27 is fixedly connected to the side of the elastic plate 26 away from the contact plate 25. A pull ring 28 is rotatably connected to the inner wall of the connecting rod 27. When the elastic plate 26 needs to be pulled upward, the angle of the elastic plate 26 can be adjusted by using the pull ring 28 on the connecting rod 27, so as to improve the speed of adjusting the angle of the elastic plate 26 through the pull ring 28. A plurality of anti-slip grooves 29 are formed at one end of the elastic plate 26. The plurality of anti-slip grooves 29 are evenly distributed on the elastic plate 26. When the elastic plate 26 contacts the battery, the anti-slip grooves 29 formed on the elastic plate 26 can improve the friction between the elastic plate 26 and the motor 21, and improve the stability of the contact between the two. The wire reel 23 is funnel-shaped. When the wire reel 23 winds up the connecting wire 24, the funnel-shaped wire reel 23 can improve the stability of the contact between the connecting wire 24 and the wire reel 23, and improve the stability of the wire reel 23 winding up the connecting wire 24;

After the contact plate 25 is used for a long time, its plate surface will be worn after long-term use. At this time, the auxiliary device 3 can be used to replace the worn contact plate 25, so that the use effect of the contact plate 25 can be improved by replacing the new contact plate 25. A plurality of connecting grooves 36 are formed in the arc surface of the rotating block 35, and the plurality of connecting grooves 36 are evenly distributed on the arc surface of the rotating block 35. When the screw rod 34 is rotated by the rotating block 35, the connecting grooves 36 formed on the rotating block 35 can increase the friction force between the rotating block 35 and the hand, so that the speed of rotating the rotating block 35 can be increased by increasing the friction force. One end of the screw rod 34 away from the rotating block 35 is fixedly connected with a guiding block 37. The cross section of the guiding block 37 is arc-shaped. When the screw rod 34 is connected to the adjusting plate 31 through the threaded hole 32, the guiding block 37 installed on the screw rod 34 can increase the connection speed between the screw rod 34 and the adjusting plate 31;

[0034] The working principle of an improved structure for reducing water ripple marks during alkaline polishing with slow lifting provided by the present utility model is as follows: When the alkaline polishing process needs to be performed on the battery chip, the elastic plate 26 is pulled in a direction away from the contact plate 25, and then the battery chip can be placed inside the elastic plate 26. Then the battery chip can be fixed on the contact plate 25 through the elastic plate 26. The other end of the battery chip is connected to the hook on the lifting plate 5. At this time, the lifting plate 5 can be adjusted by driving the power device 4. The motor 21 is started, and the rotation of the motor 21 will drive the rotating rod 22 to rotate. The rotation of the rotating rod 22 will drive the wire reel 23 to rotate. The rotation of the wire reel 23 can drive the connecting line 24 to move, so that the height of the connecting line 24 can be adjusted by the rotation of the wire reel 23, and then the height of the contact plate 25 can be adjusted by the connecting line 24, and then the side surface of the battery chip can be raised by the connecting line 24 to reduce the generation of water ripple marks.

[0035] When the worn contact plate 25 needs to be replaced, first, in the threaded hole 32, the screw rod 34 is rotated in the threaded hole 32 by rotating the rotating block 35, so that the screw rod 34 can be rotated out of the threaded hole 32 by rotating the rotating block 35. At this time, the fixing effect of the adjusting plate 31 on the contact plate 25 can be released, and the worn contact plate 25 can be pulled out of the adjusting plate 31. Then the new contact plate 25 is connected to the contact plate 25, and the contact plate 25 is fixed on the adjusting plate 31 by rotating the screw rod 34 to complete the replacement.
