[0002] Lithium-ion battery electrode coating equipment is a key piece of equipment used in the production process of lithium-ion batteries. It is mainly used to wrap the positive and negative electrodes with protective tape. Coating the lithium battery electrodes can prevent burrs and particles on the electrode edges from adversely affecting battery performance and safety, avoid mechanical damage to the electrodes during subsequent processing and use, and ensure the insulation performance between electrodes and between the electrodes and the battery casing, reducing the risk of short circuits. Existing lithium-ion battery electrode coating equipment includes an unwinding mechanism, a coating mechanism, a traction mechanism, and a winding mechanism.

[0003] The prior art, disclosed in CN205609685U, describes a lithium battery adhesive applicator. This invention solves the problem of foil exposure caused by the fixed width of the adhesive tape and the difficulty in controlling the adhesive application length in the prior art, thereby improving the quality of lithium batteries.

[0004] However, the above-mentioned prior art still has the following problems when used: because debris is generated on the surface of the lithium battery electrode during the coating process, these debris adhere to the surface of the electrode and reduce the bonding strength between the film and the lithium battery electrode. Based on this, the present invention provides a lithium battery electrode coating device with high coating efficiency and quality. Utility Model Content

It achieves automatic coating of lithium battery electrodes through a feeding assembly, a film feeding mechanism, and a pressing assembly, resulting in high coating efficiency. Furthermore, by using a nozzle to blow air onto the lithium battery electrodes, it can prevent debris from affecting the adhesion between the film and the lithium battery electrodes, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery electrode coating device, including a processing table and a feeding assembly. The feeding assembly includes a support plate, which is fixed on the top of the processing table.

[0009] The cleaning assembly includes a mounting plate, a U-shaped plate fixedly mounted on the front end of the mounting plate, and multiple nozzles fixedly mounted on the top inner wall and bottom inner wall of the U-shaped plate.

[0010] In a preferred embodiment, an electric slide is fixedly provided on one side of the front end of the processing table, and the pad is fixed on the electric slide. The electric slide is used to adjust the position of the pad, thereby automatically pressurizing the film on the lithium battery electrode.

[0011] In a preferred embodiment, an air pump is fixedly mounted on one side of the mounting plate, and the air pump is connected to multiple nozzles via hoses.

[0012] In a preferred embodiment, a feeding assembly is fixedly provided on one side of the processing table, and a circular hole is provided on the top of the processing table. The feeding assembly includes an electric rotating platform, which is fixed in the circular hole.

[0014] In a preferred embodiment, a pad supporting the lithium battery electrode is slidably disposed between two front-to-back limiting plates. A cylinder is fixedly disposed at the bottom end of each pad. The bottom end of the cylinder is fixedly inserted through the bottom of the bracket.

[0017] The technical effects and advantages of this utility model are as follows: This utility model automatically conveys lithium battery electrode sheets through a feeding component, and simultaneously uses a film feeding mechanism and a pressing component to apply film to the lithium battery electrode sheets. A cylinder and a pad are used to reinforce the film, thereby improving the film's firmness. Finally, a suction cup is used to move the lithium battery electrode sheets onto a belt conveyor, thus realizing automatic encapsulation of lithium battery electrode sheets with high encapsulation efficiency.

[0018] By using an air pump to deliver gas into multiple nozzles, the nozzles on the top and bottom inner walls of the shaped plate blow air onto the lithium battery electrode, which can remove debris from the surface of the lithium battery electrode and prevent the debris from affecting the adhesion between the film and the lithium battery electrode.

[0019] By adjusting the position of the two supports through an electric rotating platform, workers have ample time to stack multiple lithium battery electrode sheets on an empty pad while the material is being loaded. This process is repeated to shorten downtime for loading and thus improve the efficiency of encapsulation of the lithium battery electrode sheets. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Refer to the instruction manual appendix Figure 1-6 This utility model provides a lithium battery electrode coating device, including a processing table 1 and a feeding assembly 2. The feeding assembly 2 includes a support plate 201, which is fixed on the top of the processing table 1. A feeding plate 202 is provided above the support plate 201. Multiple long plates 203 are fixedly provided at the bottom of the feeding plate 202. Two cylinders 204 distributed front and rear are fixedly passed through each long plate 203. A suction cup 205 is fixedly provided at the bottom end of the piston rod of the cylinder 204.

[0034] The coating assembly 3 is used to cover the rear end of the lithium battery electrode with a film. The coating assembly 3 includes a film feeding mechanism 301, which is fixed inside the processing table 1. A film applicator 302 for applying the film to the lithium battery electrode is provided in front of the film feeding mechanism 301. It is worth noting that the film feeding mechanism 301 and the film applicator 302 are existing technologies, so they are not described in detail.

[0035] The pressure bonding assembly 4 includes a pad 401. A cylinder 402 is fixedly mounted on the front end of the pad 401. An electric slide 403 is fixedly mounted on one side of the front end of the processing table 1. The pad 401 is fixed on the electric slide 403. The position of the pad 401 can be easily adjusted by the electric slide 403, thereby automatically applying pressure to the adhesive on the lithium battery electrode.

[0036] Furthermore, a feeding assembly 6 is fixedly provided on one side of the processing table 1, and a transport frame 8 is fixedly provided on one side of the processing table 1. Two belt conveyors 9 distributed front and rear are fixedly provided on the transport frame 8. The lithium battery electrode sheets are automatically transported by the belt conveyors 9. The feeding plate 202 and the adhesive applicator 302 are both connected to the processing table 1 through an electric slide table 2 10, which is used to adjust the position of the feeding plate 202 and the adhesive applicator 302.

[0037] In operation, the electric slide 403 drives the feeding plate 202 to move. Two cylinders 204 on the left side of the feeding plate 202 move the suction cups 205 downwards, conveying the lithium battery electrode sheets from the loading assembly 6 onto the support plate 201. As the feeding of lithium battery electrode sheets continues, multiple suction cups 205 at the bottom of the feeding plate 202 continue to convey the lithium battery electrode sheets to the right side of the support plate 201. When the lithium battery electrode sheet reaches the top center position of the support plate 201, the adhesive applicator 302 automatically moves the adhesive film feeding mechanism 30... The adhesive film is attached to the rear end of the lithium battery electrode. When the lithium battery electrode with the adhesive film attached is moved to the far right of the support plate 201, the electric slide 403 drives the pad 401 to move to the rear end of the lithium battery electrode. At the same time, the cylinder 402 presses down the adhesive film to firmly attach the adhesive film to the lithium battery electrode. Then, the suction cup 205 is used to move the reinforced lithium battery electrode to the belt conveyor 9. The belt conveyor 9 is used to transport the lithium battery electrode, thereby realizing the automatic coating of the lithium battery electrode and greatly improving the coating efficiency.

[0038] Refer to the instruction manual appendix Figure 1-6 It also includes a cleaning component 5, which includes a mounting plate 501. A U-shaped plate 502 is fixedly provided at the front end of the mounting plate 501. Multiple nozzles 503 are fixedly provided on the top inner wall and bottom inner wall of the U-shaped plate 502. Gas can be sprayed out using the nozzles 503 to clean the surface of the lithium battery electrode.

[0039] An air pump 504 is fixedly installed on one side of the mounting plate 501. The air pump 504 is connected to multiple nozzles 503 through a hose. The air pump 504 automatically delivers gas, and a filter screen can be installed at the air inlet of the air pump 504 to filter the air.

[0040] When the lithium battery electrode is conveyed to the support plate 201 by the suction cup 205, the air pump 504 delivers gas into multiple nozzles 503. The nozzles 503 on the top and bottom inner walls of the shaped plate 502 blow air onto the lithium battery electrode, which can remove debris from the surface of the lithium battery electrode and prevent the debris from affecting the adhesion between the film and the lithium battery electrode.

[0041] Refer to the instruction manual appendix Figure 1-6 The processing table 1 has a circular hole 7 on its top. The feeding assembly 6 includes an electric rotating platform 601, which is fixed in the circular hole 7. The top of the electric rotating platform 601 is fixed with two front-to-back distributed supports 602. The top of the two supports 602 can be detachably fixed with two front-to-back distributed limiting plates 603 to improve the stability of the lithium battery electrode.

[0042] Furthermore, a pad 604 supporting the lithium battery electrode is slidably provided between the two front and rear distributed limiting plates 603. A cylinder 605 is fixedly provided at the bottom of each of the two pads 604. The bottom of the cylinder 605 is fixedly inserted through the bottom of the bracket 602. The pad 604 is automatically lifted by the cylinder 605, so as to facilitate the suction cup 205 to transport the lithium battery electrode.

[0043] By setting up an electric rotary platform 601 to drive two supports 602 to rotate, when all the lithium battery electrode sheets in one of the supports 602 have been fed, the electric rotary platform 601 can automatically adjust the position of the two supports 602 to continue feeding and coating. While feeding, the staff has enough time to stack multiple lithium battery electrode sheets on the empty pad 604 for processing. This process is repeated to shorten the downtime for feeding and thus improve the coating efficiency of lithium battery electrode sheets.

[0044] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
