[0033] In the related art, in order to reduce the wrinkling of the adhesive tape during the production of the battery cell, generally, a granular colloid is pasted on the clamping part of the tape pulling jaw, and the granular colloid contacts the adhesive tape to realize the clamping of the adhesive tape. However, the method of pasting the granular colloid on the clamping part has the following defects: 1) Since the operator manually pastes the granular glue to wrap the clamping part of the tape pulling jaw, the shape of the granular glue wrapping area cannot be uniformly standardized and has poor consistency, which in turn affects the adhesive tape pasting effect of the battery cell; 2) The granular glue is easily worn and needs to be replaced irregularly, resulting in material waste and high costs. In view of the above problems, the embodiment of the present application provides a tape pulling clamping member, which can make the structure of the tape pulling clamping member more uniformly standardized, have good consistency, and can reduce costs.
[0034] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.
[0035] Figure 1 is a schematic structural diagram of the tape pulling clamping member shown in the embodiment of the present application; Figure 2 is Figure 1 a partial enlarged schematic view of A in
[0036] Referring to Figure 1 and Figure 2 , the tape pulling clamping member of the present application includes a clamping main body 100, and the clamping main body 100 is provided with a base portion 101 and an end portion 102; the end portion 102 is provided with a contact portion 110 that contacts the adhesive tape, the contact portion 110 is provided with a texture, the texture is formed by arranging a plurality of convex column structures according to a set rule, and the end surfaces of the plurality of convex column structures 111 are used to contact the adhesive tape; the plurality of convex column structures 111 and the clamping member are an integrally formed structure.
[0037] The glue pulling clamping piece provided by the present application is made of metal, and a number of convex column structures 111 and the clamping piece are integrally formed structures, which can be obtained, for example, by milling or engraving the workpiece on a numerically controlled machine tool. When the clamping main body clamps the adhesive tape, the end faces of a number of convex column structures on the clamping main body are in contact with the adhesive tape. Compared with the related art, the contact area between the clamping main body and the adhesive tape can be reduced, the pressure exerted by the clamping main body on the adhesive tape per unit area is reduced, and thus the phenomenon of the adhesive tape wrinkling can be avoided or reduced.
[0038] The glue pulling clamping piece provided by the present application avoids manually pasting granular glue in the related art, makes the structure of the glue pulling clamping piece more unified and standardized, and has good consistency. Furthermore, the glue pasting effect can be improved. In addition, the defect of regularly replacing granular glue in the related art is avoided, and the cost can be reduced.
[0039] The base 101 of the glue pulling clamping piece of the present application is installed at a specific part of the glue pulling clamping mechanism through a fastener. The glue pulling clamping mechanism is provided with a driving device, and the driving device drives the glue pulling clamping piece to move towards each other relative to another clamping piece to realize the clamping of the adhesive tape. The other clamping piece can be the same as or different from the structure of the glue pulling clamping piece of the present application. The clamping piece of the present application can be a moving clamping jaw, and the other clamping piece can be a fixed clamping jaw. When in the clamping state, the contact part 110 of the glue pulling clamping piece presses the adhesive tape against the other clamping piece to prevent the adhesive tape from slipping out between the two clamping pieces, realize the clamping and pulling of the adhesive tape, and further attach the adhesive tape to the surface of the pole piece.
[0040] In the solution of the present application, the texture of the clamping part is formed by arranging a number of convex column structures 111 according to a set rule. The end faces of the number of convex column structures are in contact with the adhesive tape. Compared with the granular glue in the related art, the contact area with the adhesive layer of the adhesive tape can be reduced, and the phenomenon of glue pasting wrinkling can be more effectively avoided.
[0041] Figure 3 It is a schematic structural diagram of the convex column structure of the glue pulling clamping piece shown in the embodiment of the present application.
[0042] See Figure 3 , in some embodiments, the texture is a mesh texture; the number of convex column structures 111 are arranged along a first direction X and a second direction Y. The first direction X and the second direction Y are in the same plane and have an included angle. The end faces of the number of convex column structures 111 are in the same plane or a curved surface. This plane or curved surface is the contact surface with the adhesive layer of the adhesive tape. In this embodiment, the glue pulling direction of the glue pulling clamping mechanism is the same as the length direction of the adhesive tape, and the first direction X and the second direction Y have an included angle with the glue pulling direction. It can also be understood that a number of convex column structures are arranged obliquely relative to the glue pulling direction at the contact part 110.
[0043] In some embodiments, a flange 120 extending in the first direction X is provided at the end 102 of the clamping body 100, or a groove 130 is provided on one side of the contact portion 110, and the texture is arranged along the flange 120, so that the adhesive layer of the adhesive tape can be prevented from contacting the area outside the contact portion 110.
[0044] In some embodiments, a coating for reducing the friction coefficient is coated on the outer surface of the stud structure 111. The coating can be coated only on the end face of each stud structure or on the entire outer surface of each stud structure. Since the clamping adhesive force f of the stud end face = μ * N, where μ is the friction coefficient and N is the clamping force, after coating the coating on the outer surface of the stud, the clamping adhesive force f can be reduced, and thus the adhesive tape can be effectively prevented from wrinkling.
[0045] In some embodiments, the coating is a Teflon coating, a ceramic coating or a DLC (Diamond-Like Carbon) coating, but is not limited thereto, and other materials with high hardness and capable of reducing the friction coefficient can also be used.
[0046] See Figure 3 , in some embodiments, the stud structure 111 is rectangular, one side of the end face of the stud structure 111 is parallel to the first direction X, and the adjacent other side is parallel to the second direction Y. The lengths of the two sides can be equal or unequal.
[0047] In some embodiments, the length d and width w of the stud structure 111 are 0.80 mm - 1.2 mm, preferably 1 mm; the height h of the stud structure 111 is 0.1 mm - 0.3 mm, preferably 2 mm. In some embodiments, the spacing S1 between adjacent stud structures 111 in the first direction X is 0.1 mm - 0.3 mm, preferably 0.2 mm, and the spacing S2 in the second direction Y is 0.3 mm - 0.7 mm, preferably 0.5 mm; after setting the dimensions of the stud structure 111 of the present application to the above parameters, the contact area with the adhesive layer of the adhesive tape can be reduced, the clamping adhesive force between the end faces of several stud structures 111 and the adhesive tape can be reduced, and thus the wrinkling of the adhesive tape can be reduced or avoided.
[0048] It should be noted that the convex post structure of the present application is not limited to the rectangle described above. In other embodiments, it can also be cylindrical or conical with a flat end face. When the convex post structure of the present application is rectangular, it is not limited to the above size parameters, and the above size parameters can be adjusted according to actual situations. The present application also provides a glue pulling clamping mechanism, including a body, on which a glue pulling clamping member as described in the above embodiment is installed. The base 101 of the glue pulling clamping member is installed on the glue pulling clamping mechanism, and the glue pulling clamping mechanism is provided with a driving device, which drives the glue pulling clamping member to move relative to another clamping member to clamp the adhesive tape. When in the clamping state, the contact portion 110 of the glue pulling clamping member presses the adhesive tape to prevent the adhesive tape from coming off.
[0049] In the glue pulling clamping mechanism of the present application, since the texture on the glue pulling clamping member is formed by arranging a plurality of convex post structures according to a set rule, and the end faces of the plurality of convex post structures 111 are in contact with the adhesive tape, compared with the particle glue in the related art, it can reduce the contact area with the adhesive layer of the adhesive tape and can more effectively avoid the phenomenon of the adhesive tape wrinkling.
[0050] The above has described the embodiments of the present application. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, the practical application or the improvement of the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the disclosed embodiments.
