Description

Technical Field

[0001] This utility model belongs to the field of new energy battery technology, specifically relating to a new energy battery electrode slurry coating device. Background Technology

[0002] New energy battery electrodes are one of the core components of batteries, directly affecting battery performance and lifespan. They serve as the carrier of current. Aluminum foil is commonly used for the positive electrode, while copper foil is often used for the negative electrode. Active materials include lithium iron phosphate, ternary materials, etc. for the positive electrode; and graphite, silicon-carbon composite materials, etc. for the negative electrode. In the manufacturing process of the electrodes, the uniform coating of the slurry is crucial to the electrical performance of the battery.

[0003] In the prior art, such as the battery electrode slurry coating device for new energy battery production with application number 202310885456.X, there is a base. Two sets of oppositely distributed vertical plates are fixedly installed on the surface of the base. A raw material roller is rotatably installed at the top of the two sets of vertical plates, and a winding roller is rotatably installed at the bottom of the two sets of vertical plates. A storage box is fixedly installed on the two sets of vertical plates. A coating mechanism is provided in the storage box. The coating mechanism includes a wiping roller, a rotating component, a feeding component, and a scraping component.

[0004] In the above, the close cooperation between different components has basically achieved the coverage effect of the electrode sheet, which meets the process requirements of the battery electrode sheet to a certain extent. However, after reading the technical solution, it is found that the contact area between the cylindrical surface of the wiping roller and the electrode sheet is too small. This results in the slurry coating on the electrode sheet surface being not continuous enough, and the coverage area cannot meet the process requirements of the electrode sheet. In addition, the fixedly installed wiping roller can only press the slurry onto the electrode sheet surface through surface friction, which may cause some areas of the electrode sheet surface to be damaged by pressing, thereby affecting the yield of the electrode sheet.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model embodiment proposes a new energy battery electrode slurry coating device, including a base 1; for example, such as Figures 1-3 As shown.

[0024] A sliding block 4 is placed on the top of the base 1. A protective plate 5 is provided on the side of the sliding block 4. An insert shaft 6 is provided on the opposite side of the protective plate 5. A rotating ring 7 is rotatably sleeved on the surface of the insert shaft 6. A coating component 8 is provided in cooperation with the rotating ring 7. The coating component 8 includes a swing arm 81 installed on the outer surface of the rotating ring 7. A transfer ring seat 82 is provided on the end face of the swing arm 81 away from the rotating ring 7. A support shaft 83 is adapted to be installed in the inner cavity of the transfer ring seat 82. A mating tooth block 84 is provided on the end face of the transfer ring seat 82. A fastening strip 85 is installed on the inclined surface of the mating tooth block 84. A coarse coating roller 86 is provided at one end of the mating tooth block 84.

[0025] The coarse coating roller 86 is provided with a spring crank 87 on its side, and a first fine coating roller 9 is adapted to be installed on the bottom end face of the spring crank 87.

[0026] A straight spring 10 is provided on the surface of the first fine coating roller 9, and a second fine coating roller 11 is mounted on the side of the straight spring 10, and the initial position of the second fine coating roller 11 is different from that of the first fine coating roller 9.

[0027] Specifically, the sliding block 4, protective plate 5, and insert shaft 6 are designed to ensure greater safety on the side of the sliding block 4 during sliding and avoid the problem of sliding vibration, thereby indirectly ensuring the continuous and stable coating effect of the coating material on the coated part 8. The rotating ring 7 allows for more sufficient contact of the coarse coating roller 86 and a larger coating surface. The intermediate ring seat 82 and support shaft 83 work together to enable the swing arm 81 to achieve a hinged rotation effect, further improving the uniform contact effect of the coarse coating roller 86. The slurry can be better spread on the surface of the electrode sheet 13. The installation of the connecting tooth block 84 and fastening strip 85 allows the coarse coating roller 86 to be flexibly disassembled and assembled. When the surface of the coarse coating roller 86 is covered with too much slurry, it can be disassembled immediately to ensure that the slurry does not accumulate and adhere on the surface of the electrode sheet 13, resulting in higher coating precision. Furthermore, the spring crank 87 and the first fine coating roller 9 are adapted to each other, allowing the slurry to be coated multiple times, reducing the discontinuity of the coating area, and also meeting the process requirements of uniform spreading of the electrode sheet 13.

[0028] The top of the first fine coating roller 9 is fitted with a slow-descent member 12; for example, such as Figures 2-4 As shown.

[0029] The deceleration element 12 includes a connecting rod 121 that is connected to the outside of the first fine coating roller 9.

[0030] The top surface of the connecting rod 121 is fitted with a buffer plate 122, and a positioning inner cylinder 123 is adapted to be installed on one side of the buffer plate 122. The top of the positioning inner cylinder 123 is installed with the mating tooth block 84.

[0031] The inner side of the sliding block 4 is slidably fitted with a slide rail 2. The bottom of the slide rail 2 is fixedly installed with the base 1, and an electromagnetic block 3 is provided on the top of the slide rail 2.

[0032] Specifically, the cooperation between the slow-descent component 12 and the first fine coating roller 9 allows the coating of the first fine coating roller 9 to be slow and comprehensive, effectively compensating for the uneven thickness of the slurry on the surface of the electrode sheet 13. At the same time, the sliding cooperation between the connecting rod 121, the buffer plate 122, and the positioning inner cylinder 123 helps to stabilize the first fine coating roller 9 when it descends. Furthermore, the cooperation between the electromagnetic block 3, the slide rail 2, and the sliding block 4 allows the electromagnetic block 3 to generate a magnetic field when it is connected to an external power source. The sliding block 4 then detaches from the surface of the slide rail 2 and slides along the direction of the slide rail 2. This electromagnetic sliding method helps the sliding block 4 achieve a uniform speed displacement, ultimately making the coating of the first fine coating roller 9 more continuous.

[0033] The lower surface of the second fine coating roller 11 is fitted with an electrode sheet 13; for example, such as Figures 3-5 As shown.

[0034] A conveyor belt 14 is provided at the bottom of the electrode 13, and a stabilizing base 15 is provided at the bottom of the conveyor belt 14.

[0035] The number of coating parts 8 is two sets, and the two sets of coating parts 8 are symmetrically arranged on the side of the slide rail 2.

[0036] Specifically, by cooperating with the conveyor belt 14, the electrode 13 can be transported continuously, thereby improving the coating effect of the electrode 13 and shortening unnecessary time.

[0037] Working principle: First, the electromagnetic block 3 is energized, and then the electromagnetic block 3 generates magnetic force. Then, the magnetic force will cause the sliding block 4 to disengage from the slide rail 2 and slide the sliding block 4 in a straight line along the slide rail 2. During the sliding process, the second fine coating roller 11 first contacts the electrode 13. Then, the second fine coating roller 11 is subjected to force and deflects at an angle. Through the elastic transmission effect of the straight spring 10, the first fine coating roller 9 is driven to deflect at an angle, so that the first fine coating roller 9 and the second fine coating roller 11 complete multiple coatings of the slurry on the surface of the electrode 13. Then, the first fine coating roller 9 pushes the coarse coating roller 86 to deflect through the spring crank 87. This deflection will cause the intermediate ring seat 82 to rotate along the surface of the support shaft 83.

[0038] When the transfer ring seat 82 is hinged and rotated, the swing arm 81 set on the side can provide a stable rotation support to help the coarse coating roller 86 swing stably. The electromagnetic sliding of the previous sliding block 4 can allow the coarse coating roller 86, the first fine coating roller 9 and the second fine coating roller 11 to continuously abut against the electrode sheet 13, so as to achieve multiple and comprehensive coating of the slurry.
