AI Technical Summary
Explosion-proof valve plates are prone to sticking together in the tooling due to static electricity or surface characteristics. This causes the nozzle to pick up another plate below it, resulting in poor welding or positional displacement. Furthermore, the stuck plates are deformed by external pressure when separated, affecting sealing and safety.
Design a tooling for feeding explosion-proof valve discs and preventing material sticking. The tooling includes a main body and an anti-sticking component. A brush holder and brush bristles are installed in the receiving groove. The brush bristle density is 100-120 bristles/cm2, the bristle tips are upturned at 45°-85°, the diameter gradually decreases, and the hardness gradually decreases. It is used to separate the stuck explosion-proof valve discs. The tooling is easy to maintain and replace through the cooperation of the plug-in post and the cover plate.
Ensure that only a single explosion-proof valve piece is picked up each time to avoid incomplete welding or misalignment, prevent deformation, improve welding yield to 98%, and reduce deformation rate to below 1%.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy battery manufacturing technology, specifically to a tooling for feeding explosion-proof valve plates and preventing material sticking. Background Technology
[0002] During the manufacturing process of the power battery cover, the explosion-proof valve plate needs to be fed into the explosion-proof valve hole of the substrate through a suction nozzle for laser welding.
[0003] In existing technologies, explosion-proof valve plates are prone to sticking together within the tooling due to static electricity or surface characteristics. This causes the suction nozzle to pick up one explosion-proof valve plate along with another below it, resulting in the following problems:
[0004] First, the adhered explosion-proof valve plates were simultaneously welded to the substrate, resulting in poor soldering or misalignment.
[0005] Second, the adhesive sheet is deformed by external force when it separates from the nozzle, affecting the sealing performance and safety. Utility Model Content
[0006] This utility model provides a tooling for feeding explosion-proof valve plates to prevent material sticking, which can solve the problems of poor welding and deformation of explosion-proof valve plates caused by adhesion during the manufacturing process of battery cover plates in the prior art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] An explosion-proof valve plate feeding and anti-sticking tooling includes a tooling body with a receiving groove for stacking explosion-proof valve plates. An anti-sticking material component is provided in the receiving groove and contacts the explosion-proof valve plates placed in the receiving groove to brush the explosion-proof valve plates that are stuck to the bottom into the receiving groove.
[0009] As a further embodiment of this utility model: the anti-sticking material assembly is installed on the left and right inner sidewalls of the receiving groove.
[0010] As a further embodiment of this utility model: the anti-sticking material assembly includes a brush bracket and brush bristles, the brush bracket is fixedly fitted to the inner side wall of the receiving groove, and the brush bristles are evenly distributed on the surface of the brush bracket.
[0011] As a further aspect of this utility model: the bristles are made of nylon fiber, and the bristle density is 100-120 bristles / cm². 2 The bristle length is 3-5mm.
[0012] As a further embodiment of this utility model: the tips of the bristles are upturned at an angle of 45°-85°.
[0013] As a further aspect of this invention: the diameter of the bristles gradually decreases from the tail end to the tip, and the hardness gradually decreases.
[0014] As a further embodiment of this utility model: the tooling body includes a base and a main body, the main body is vertically disposed on the base, and the receiving groove extends from the top of the main body to the bottom of the main body.
[0015] As a further embodiment of this utility model: the tooling body also includes a cover plate, which is detachably fitted onto the side of the receiving groove with an opening.
[0016] As a further embodiment of this utility model: a plug-in post is provided on the side of the main body, and a plug-in hole matching the plug-in post is provided on the cover plate. The cover plate is fixedly covered on the side of the main body through the cooperation of the plug-in hole and the plug-in post.
[0017] As a further embodiment of this utility model, a handle is also installed on the outer side of the cover plate.
[0018] The beneficial effects of this utility model are:
[0019] (1) This utility model provides a receiving groove for stacking explosion-proof valve pieces on the main body of the tooling, and sets an anti-sticking material component in the receiving groove. The anti-sticking material component contacts the explosion-proof valve pieces placed in the receiving groove. When the suction nozzle lifts the explosion-proof valve pieces upward, the lower layer of explosion-proof valve pieces that are stuck together are brushed downward by the resistance of the anti-sticking material component, get out of the adsorption force range, and fall back into the receiving groove. This ensures that only one piece is picked up each time, so that there is no interference from the stuck pieces during laser welding, avoiding false welding or positional displacement, and at the same time preventing the explosion-proof valve pieces from being deformed due to sticking and squeezing.
[0020] (2) The anti-sticking material component of this utility model includes a brush holder and brush bristles. The brush bristles are evenly distributed on the surface of the brush holder with a density of 100-120 bristles / cm². 2 The bristles are pointed upwards at an angle of 45°-85°, and the diameter of the bristles gradually decreases from the tail to the tip, while the hardness gradually decreases. Such bristles can effectively separate the adhered explosion-proof valve plates, while avoiding scratching the explosion-proof valve plates due to excessive hardness.
[0021] (3) This utility model provides a set of plug-in posts on the side of the main body and opens plug-in holes on the cover plate that match the plug-in posts. The cover plate is fixedly covered on the side of the main body through the cooperation of the plug-in holes and the plug-in posts. The cooperation design of the cover plate and the plug-in posts facilitates tooling maintenance and replacement of anti-sticking components. Attached Figure Description

[0030] Please see Figure 1As shown, this embodiment provides a tooling for feeding explosion-proof valve plates with anti-sticking material, including a tooling body 1, a receiving groove 2, an anti-sticking material assembly 3, and a cover plate 13. The tooling body 1 consists of a base 11 and a main body 12. The main body 12 is vertically fixed to the base 11, which stabilizes the tooling and facilitates its installation at a suitable position on the power battery cover plate manufacturing production line. The receiving groove 2 extends from the top to the bottom of the main body 12, and multiple receiving grooves 2 can be provided. The receiving groove 2 is used for stacking explosion-proof valve plates 4. Anti-sticking material assemblies 3 are symmetrically installed on the left and right inner walls of the receiving groove 2. The anti-sticking material assemblies 3 contact the explosion-proof valve plates 4 stacked in the receiving groove 2. When the suction nozzle picks up a single explosion-proof valve plate 4, it also picks up another explosion-proof valve plate 4 below it. The anti-sticking material assembly 3 is used to brush the other explosion-proof valve plate 4 adhering below it into the receiving groove 2.
[0031] It is worth noting that the base 11 and body 12 of the tooling body 1 are both made of anti-static material to further reduce adhesion caused by static electricity.
[0032] Please see Figure 3 As shown, in this embodiment, the anti-sticking material component 3 includes a brush holder 31 and brush bristles 32. The brush holder 31 is fixedly attached to the inner wall of the receiving groove 2 by adhesive or bolts. The brush bristles 32 are evenly distributed on the surface of the brush holder 31. The material of the brush bristles 32 can be nylon fiber with a density of 100-120 fibers / cm. 2 The bristles 32 are 3-5mm in length. The tips of the bristles 32 curve upwards at an angle of 45°-85°, and the diameter and hardness of the bristles 32 gradually decrease from the tail end to the tip. This design effectively separates the adhered explosion-proof valve plates 4 while avoiding scratches caused by excessive hardness. Through the specific angle, density, and gradually changing hardness of the bristles 32, non-destructive separation of the adhered plates is achieved.
[0033] Please see Figure 1 As shown, in this embodiment, the cover plate 13 is detachably fitted onto the side of the receiving groove 2 that has an opening. Specifically, please refer to... Figure 2 As shown, a set of plug-in pins 14 can be provided on the side of the main body 12. Please refer to [link / reference]. Figure 1 As shown, a mating hole 15 matching the plug post 14 is provided on the cover plate 13. The cover plate 13 is fixedly covered to the side of the body 12 through the mating of the mating hole 15 and the plug post 14. A handle 16 is also installed on the outside of the cover plate 13. The mating design of the cover plate 13 and the plug post 14 facilitates tooling maintenance and replacement of the anti-stick material assembly 3.
[0034] Installation and operation steps of this utility model:
[0035] Explosion-proof valve plate 4 loading: Stack the explosion-proof valve plates 4 into the receiving groove 2 and cover them with the removable cover plate 13. The cover plate 13 is fixed by the insertion post 14 on the side of the body 12 and the insertion hole 15 on the cover plate 13, and can be easily opened and closed by the outer handle 16.
[0036] Nozzle feeding: The nozzle picks up the top explosion-proof valve plate 4 from the top of the fixture. At this time, if the lower explosion-proof valve plate 4 sticks together due to static electricity or surface characteristics, the upward-curving tip of the bristles 32 will come into contact with the sticky explosion-proof valve plate 4.
[0037] Anti-sticking process: When the suction nozzle lifts the explosion-proof valve plate 4 upwards, the stuck lower explosion-proof valve plate 4 is brushed downwards by the elastic resistance of the bristles 32, gets out of the adsorption range, and falls back into the receiving tank 2, ensuring that only one piece is picked up each time.
[0038] Welding process: The explosion-proof valve plate 4 is precisely placed in the explosion-proof valve hole of the base plate. There is no interference from the sticky pieces during laser welding, which avoids poor welding or positional displacement, and at the same time prevents the explosion-proof valve plate 4 from being deformed due to adhesion and squeezing.
[0039] Tests showed that after adopting this tooling, the welding yield of the explosion-proof valve plate 4 increased from the original 85% to 98%, and the deformation rate of the explosion-proof valve plate 4 decreased from 7% to below 1%.
[0040] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
