Description
Technical Field
[0001] This utility model relates to the field of battery blue film cleaning technology, specifically a battery blue film laser adhesive removal device. Background Technology
[0002] Lithium-ion batteries, as a type of high-performance battery, use lithium metal or lithium alloy as their positive and negative electrode materials and employ a non-aqueous electrolyte solution. Due to their significant advantages such as high energy density, low self-discharge rate, and long lifespan, these batteries are widely used in numerous fields including new energy vehicles, aerospace, and mobile devices.
[0003] In the production process of pouch lithium batteries, applying the blue film is a crucial step. In the context of pouch lithium battery formulations, the main function of the blue film is to encapsulate the entire battery cell, forming a unified whole and providing effective protection during transportation and distribution, achieving dust and water resistance. However, when further processing of the pouch lithium batteries with the blue film applied is required, the blue film needs to be removed. To improve the efficiency of blue film removal, a battery blue film laser adhesive removal device is typically used to complete the removal process.
[0004] Furthermore, most existing battery blue film methods involve wrapping the battery cell around its perimeter, which presents problems during the subsequent blue film removal process. On the one hand, since the adhesive needs to be removed from all four sides of the battery, it is inconvenient to flip the battery during the operation, which greatly reduces the efficiency of the adhesive removal work and increases the difficulty of the operation. On the other hand, after laser adhesive removal, a small amount of adhesive spots may remain on the battery surface. These residual adhesive spots will cause inconvenience to the subsequent blue film peeling work and affect the integrity and quality of the blue film removal. Utility Model Content
[0005] The purpose of this invention is to provide a laser adhesive removal device for blue film on batteries, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery blue film laser adhesive removal device, comprising a substrate, a protective frame on the substrate, a laser head inside the protective frame via a robotic arm, a battery body on the substrate via a conveying assembly, a scraping assembly at the output end of the robotic arm, and a flipping mechanism on the substrate via an adjusting assembly, the flipping mechanism being matched with the battery body.
[0007] Preferably, in order to facilitate the transport of the battery body and subsequent operations such as degumming and cleaning, the transport assembly includes a transport guide rail set on the base, a guide rail slider slidably fitted on the transport guide rail, a movable plate set on the guide rail slider, and a placement platform set on the movable plate for placing the battery body.
[0008] Preferably, in order to scrape off the blue film after laser adhesive removal and thus avoid the impact of a small number of adhesive spots on subsequent peeling, the scraping component includes a connecting post at the end of the robotic arm, a locking block is fixedly provided at the end of the connecting post, and a scraper is provided inside the locking block.
[0009] Preferably, to avoid affecting contact, the end of the scraper away from the block is provided with an elastic layer.
[0010] Preferably, in order to facilitate the adjustment of the distance between the flipping mechanism and the battery body, and thus realize operations such as clamping, the adjustment component includes vertical plates symmetrically arranged on the base, and electric push rods are symmetrically arranged on the side walls of the two vertical plates that are close to each other.
[0011] Preferably, in order to facilitate the flipping of the battery body and the removal of adhesive and scraping operations on each surface, the flipping mechanism includes an adjustment plate connected to the output ends of two electric push rods on the same vertical plate. One adjustment plate has a motor in the middle and the other adjustment plate has a rotating rod in the middle. Both the output end of the motor and the end of the rotating rod are equipped with clamping components.
[0012] Preferably, in order to ensure the clamping effect, the clamping assembly includes clamping plates that are fixedly connected to the motor output end and the end of the rotating rod, respectively, and positioning pads are provided on the end faces of the two clamping plates that are close to each other.
[0013] Compared with the prior art, the beneficial effects of this utility model are: A robotic arm controls a laser head to remove adhesive from the battery body using laser technology. Utilizing the high energy density of the laser, the adhesion between the adhesive layer and the blue film is effectively broken, achieving highly efficient adhesive removal. Simultaneously, the robotic arm's output end is equipped with a scraping component, which can scrape the surface of the battery body after laser adhesive removal, further separating the blue film from the adhesive layer. This prevents residual adhesive from affecting subsequent peeling operations, improving the quality and efficiency of adhesive removal and scraping. The adjustment assembly and the flipping mechanism work together to enable convenient flipping and clamping of the battery body. The electric push rod in the adjustment assembly can flexibly adjust the distance between the flipping mechanism and the battery body, facilitating clamping operations. The motor, rotating rod, and clamping assembly in the flipping mechanism can achieve stable flipping of the battery body, ensuring smooth removal of adhesive and scraping operations on all sides.

Detailed Implementation
[0016] 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.
[0017] Please see Figures 1-4 One embodiment of this utility model provides a laser adhesive removal device for blue film on batteries, comprising a substrate 11, on which a protective frame 12 is provided, the protective frame 12 as follows: Figure 1Except for the frame and top, the surrounding sides can be made of transparent material, such as glass, to allow for easy access to the interior. Alternatively, they can be opaque and made of metal for protection during laser adhesive removal. Inside the protective frame 12, a laser head 14 is mounted on the end flange of the robotic arm 13 via a robotic arm 13. The laser head 14 is connected to a controller via a signal line. A motion controller is also provided to coordinate the movement of the robotic arm 13 and laser triggering, analyze the CAD path or teaching trajectory, and output control signals. The sensor system monitors laser power, temperature, and position deviation in real time, such as infrared temperature sensors, vision cameras, and auxiliary devices. Cooling systems can use air cooling / water cooling and smoke extraction / dust removal devices, which are relatively mature technologies and will not be elaborated here. The base 11 has a battery body, mainly a new energy battery, mounted on it via a conveying assembly. The blue film on the surface of the battery body is removed. The output end of the robotic arm 13 also has a scraping assembly. The base 11 has a flipping mechanism via an adjustment assembly. The flipping mechanism matches the battery body to facilitate the conveying of the battery body, subsequent adhesive removal, and to cooperate with the flipping mechanism to flip the battery body. The adhesive removal operation can be performed on other surfaces. The conveying component includes a conveying guide rail 21 set on the base 11. The conveying guide rail 21 can be driven by a linear motor 53 or by other means such as a reciprocating screw to achieve reciprocating movement, thereby conveying the battery body. A guide rail slider 22 is slidably fitted on the conveying guide rail 21. A moving plate 23 is set on the guide rail slider 22. A placement platform 24 for placing the battery body is set on the moving plate 23. An anti-slip pad, which can be made of rubber or other anti-slip materials, can be glued to the placement platform 24 to ensure stability during placement and prevent slippage during conveying.
[0018] Please see Figures 1-4To facilitate the flipping of the battery body for easy cleaning of other surfaces and to facilitate the scraping of the blue film after adhesive removal, a scraping mechanism is provided at the end of the robotic arm 13, located on one side of the laser head 14. This scraping mechanism includes a connecting post 41 at the end of the robotic arm 13, with a locking block 42 fixed to its end. The locking block 42 has a groove for securing the scraper 43, which can be fastened with bolts or by using limiting methods such as limiting posts and limiting holes. It is detachable. The scraper 43 is located inside the locking block 42, with an elastic layer 44 (made of rubber or silicone) at the end away from the locking block 42 to prevent sharp edges. To prevent sharp objects from contacting the blue film and to prevent puncture or cut, and to facilitate the adjustment of the distance between the two flipping mechanisms for easy clamping of the battery body, the base 11 is symmetrically provided with adjustment components. The adjustment components include vertical plates 31 symmetrically arranged on the base 11, and electric push rods 32 are symmetrically provided on the side walls of the two vertical plates 31 that are close to each other. The flipping mechanism includes adjustment plates 51 connected to the output ends of the two electric push rods 32 on the same vertical plate 31. One adjustment plate 51 has a motor 53 in the middle, and the other adjustment plate 51 has a rotating rod 52 in the middle. The output end of the motor 53 and the end of the rotating rod 52 are both provided with clamping components. The clamping components include clamping plates 54 that are fixedly connected to the output end of the motor 53 and the end of the rotating rod 52 respectively. The end faces of the two clamping plates 54 that are close to each other are provided with positioning pads 55.
[0019] Working Principle: In use, the battery body to be cleaned is placed on the placement platform 24. The conveyor rail 21, in conjunction with the guide rail slider 22, moves the placement platform 24 on the moving plate 23. When it reaches the flipping mechanism, the movement stops. An electric push rod 32 extends, bringing the two adjusting plates 51 closer together. The clamping plate 54 and positioning pad 55 clamp the battery body. The conveyor rail 21 then moves the guide rail slider 22 and the moving plate 23 back to their original positions. Finally, a robotic arm 13 moves the laser head 14 to remove the adhesive from the battery body. The high energy density of the laser causes thermal decomposition and carbonization of the adhesive layer. The adhesive layer may vaporize, thereby destroying the adhesion between the adhesive layer and the substrate, such as the blue film. After one side is completed, the motor 53 works in conjunction with the rotating rod 52 to rotate and flip the clamping plate 54 and the battery body, so that the adhesive can be removed from the next side. The above operation is repeated to remove the adhesive from all four sides of the battery body. Then, the robot arm 13 flips the battery body and rotates the scraper 43 to the working surface. The scraper 43 can be moved to scrape the surface of the battery body. For the small amount of adhesive residue after laser treatment, the scraping can further separate the blue film from the adhesive layer through mechanical force. Then, the flipping mechanism flips the battery body to scrape the other sides, which facilitates the subsequent peeling of the battery body from the blue film.
[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this 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 this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
