Description

TECHNICAL FIELD

[0001] The utility model relates to battery technology field especially relates to a battery pole piece pasting rubber equipment. BACKGROUND

[0002] In the preparation process of the winding type battery cell, the positive pole piece, the diaphragm and the negative pole piece form a laminated structure by winding. Among them, the positive pole piece usually takes aluminum foil as the current collector. However, due to the relatively low ductility of aluminum foil material, in the pressure shaping process after winding, the positive pole piece in the winding corner area, that is, the curvature mutation part of the pole piece transition from a straight line segment to an arc segment, is easily affected by mechanical stress concentration, resulting in microcracks or even tearing defects of the aluminum foil substrate. Such defects not only cause the active material to fall off, reducing the battery capacity, but also may cause internal short circuit and other safety hazards.

[0003] To solve the above problems, the existing technology generally adopts the process scheme of pre-pasting adhesive tape at the winding corner position of the positive pole piece, disperses stress through the adhesive bonding and reinforcement of the adhesive tape, thereby improving the tearing resistance of the aluminum foil. However, the traditional pasting mechanism device has poor retrofit adaptability. When the pole pieces of different specifications of battery cells are used, complex manual adjustment of the pasting position and the like is required, resulting in low production line retrofit efficiency.

[0032] In the description of the present application, it should be pointed out that the directions or position relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application in that the indicated devices or elements must have a specific direction, be constructed and operated in a specific direction.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0034] Please refer to Figures 1 to 11A battery electrode bonding device includes a longitudinal frame plate 1 and an unwinding roller 2, a bonding module 4, a buffer module 5, and a take-up roller 3 disposed on the longitudinal frame plate 1. The unwinding roller 2 is used to assemble the electrode roll to be bonded.

The first bonding section 41a and the second bonding section 41b are arranged sequentially along the conveying direction of the battery electrode 6. The second bonding structure 49 of the second bonding section 41b can be close to or away from the first bonding structure 46 of the first bonding section 41a. A plurality of first guide rollers are disposed between the bonding module 4 and the unwinding roller 2. The bonding plate 41 is installed on the longitudinal frame plate 1. The take-up roller 3 is used to assemble the bonded electrode roll. The buffer module 5 is used to buffer the bonded battery electrode 6 so that the bonded battery electrode 6 can be continuously wound up at the take-up roller 3. In this embodiment, the battery electrode 6 is unwound by the self-unwinding roller 2, passes sequentially through the adhesive application module 4 and the buffer module 5, and then is wound onto the winding roller 3. For example... Figure 1 As shown, in this embodiment, there are two unwinding rollers 2 and two take-up rollers 3. A manual tape-joining module is provided on the longitudinal frame plate 1 near the unwinding roller 2, so that the battery electrode 6 can be joined on the two unwinding rollers 2 by tape joining, reducing the battery electrode 6 loading time and improving work efficiency.
