Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to a novel tunnel furnace gripper mechanism. Background Technology

[0002] The lithium battery industry, both domestically and internationally, has promising development prospects. Lithium-ion batteries, with their unique performance advantages, have been widely used in portable electronic devices such as laptops, cameras, and mobile communications. The widespread application of lithium batteries in the electric vehicle industry, especially with the emergence of lithium iron phosphate batteries, has further propelled the development and application of the lithium battery industry. To ensure high-quality lithium batteries, strict control over the production environment is necessary for each step in the lithium battery manufacturing process. During lithium battery production, bare cells, electrodes, electrode rolls, and the cells themselves require preheating or drying.

[0003] The existing lithium battery preheating and baking is achieved through existing heating tunnel furnaces, which require a corresponding gripper mechanism. The gripper position of the existing tunnel furnace gripper mechanism is fixed and locked, and cannot be adjusted. When there is a deviation in position, the entire mechanism needs to be adjusted, which is time-consuming, labor-intensive, inefficient, and difficult to adjust. At the same time, the gripper is coated with rubber, resulting in an uneven surface and easy adhesion of ceramic powder clumps, which can damage the battery cell and pose a quality risk. Because it is easy to attract ceramic powder, it needs to be cleaned every 4 hours, which consumes a lot of manpower. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing tunnel furnace gripper mechanism has a fixed and locked gripper position that cannot be adjusted, which can easily damage the battery cells and pose a quality hazard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel tunnel furnace gripper mechanism is characterized by comprising a connecting plate and a gripper assembly detachably mounted on the connecting plate. The gripper assembly includes a gripper fixing plate and a gripper body detachably mounted on the gripper fixing plate. The gripper body is a Teflon gripper.

[0007] A further improvement is that the connecting plate includes several downwardly extending first mating plates, and the first mating plates are provided with several mating threaded holes.

[0008] A further improvement is that the connecting plate is provided with several threaded holes for connecting with the robotic arm inside the tunnel.

[0009] A further improvement is that the gripper fixing plate includes a second docking plate for docking with the first docking plate and a third docking plate for docking with the gripper body.

[0010] A further improvement is that the second mating plate has at least one connecting groove arranged along the length of the second mating plate, and also includes mating screws for the clamping fixing plate to be detachably mounted on the connecting plate, which are used in conjunction with the connecting groove and the mating threaded hole.

[0011] A further improvement is that the gripper body and the third docking plate have a gripper fixing groove on their corresponding surfaces for docking and cooperating with the third docking plate, and the third docking plate is inserted into the gripper fixing groove.

[0012] A further improvement is that: a gripper positioning post is provided on the bottom surface of the gripper fixing groove, and a gripper positioning hole is provided on the third docking plate at the corresponding position of the gripper positioning post, which cooperates with the gripper positioning post; the gripper positioning post is inserted into the gripper positioning hole.

Detailed Implementation

[0024] See Figures 1-5 As shown, the technical solution adopted in this specific embodiment is: a novel tunnel furnace gripper mechanism, including a connecting plate 1 and a gripper assembly detachably mounted on the connecting plate 1. The gripper assembly includes a gripper fixing plate 2 and a gripper body 3 detachably mounted on the gripper fixing plate 2. The gripper body 3 is a Teflon gripper.

[0025] Among them, the use of Teflon grippers has a smooth surface that does not stick to ceramic powder, which can eliminate the risk of damaging the battery cell. At the same time, it reduces the cleaning frequency of the grippers to once a week, greatly improving labor efficiency.

[0026] The connecting plate 1 includes several downwardly extending first docking plates 12, and several docking threaded holes 13 are provided on the first docking plates 12.

[0027] The connecting plate 1 is provided with a plurality of threaded holes 11 for connecting with the robotic arm inside the tunnel.

[0028] The gripper fixing plate 2 includes a second docking plate 21 for docking with the first docking plate 12 and a third docking plate 22 for docking with the gripper body 3.

[0029] The second docking plate 21 has at least one connecting groove 23 arranged along the length of the second docking plate 21, and also includes docking screws for the clamping fixing plate 2 to be detachably installed on the connecting plate 1, which are used in conjunction with the connecting groove 23 and the docking threaded hole 13.

[0030] The gripper body 3 and the third docking plate 22 are provided with gripper fixing grooves 32 for docking and cooperating with the third docking plate 22, and the third docking plate 22 is inserted into the gripper fixing grooves 32.

[0031] The bottom surface of the gripper fixing groove 32 is provided with a gripper positioning post 33, and the third docking plate 22 is provided with a gripper positioning hole 25 corresponding to the gripper positioning post 33, which cooperates with the gripper positioning post 33. The gripper positioning post 33 is inserted into the gripper positioning hole 25.

[0032] The third docking plate 22 is provided with a plurality of first claw fixing threaded holes 24 on its upper part. The claw body 3 is provided with a second claw fixing threaded hole 31 at the position corresponding to the first claw fixing threaded holes 24. It also includes claw fixing screws 4 for detachably mounting the claw body 3 on the claw fixing plate 2, which cooperate with the first claw fixing threaded holes 24 and the second claw fixing threaded holes 31.

[0033] The mating screws and the clamp fixing screws are all hexagonal screws.

[0034] The working principle of this utility model is as follows: In use, first, the third mating plate of the gripper fixing plate is inserted into the gripper fixing groove. The gripper positioning pin is then inserted into the gripper positioning hole for positioning. Next, the gripper fixing screws are used to fix the gripper in conjunction with the first and second gripper fixing threaded holes. Then, the second mating plate of the gripper fixing plate is mated to the first mating plate of the connecting plate and fixed by mating screws in conjunction with the connecting groove and mating threaded hole. If the gripper position needs to be adjusted, simply unscrew the mating screws, adjust the position of the second mating plate on the first mating plate, and then tighten the mating screws. The use of a mating groove along the length of the second mating plate instead of conventional threaded holes allows for easy adjustment and fixing, resulting in greater applicability. The gripper body is made of Teflon, with a smooth surface that does not adhere to ceramic powder, eliminating the risk of cell damage. The introduction of Teflon grippers reduces the cleaning frequency to once a week, greatly improving labor efficiency. The detachable installation of the gripper body facilitates replacement and maintenance, making it convenient to use and highly applicable.
