Embodiment Construction

[0035] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0036] The gluing equipment provided in this embodiment includes a gluing device and a gluing preparation device.

[0037] The gluing device includes a machine frame, gluing power components and pressing belt parts. The frame is used to provide support for the device, and the glue-applying power assembly is installed on the frame for outputting reciprocating motion. The pressing tape part is connected with the gluing power assembly, and the gluing power assembly drives the pressing tape part at least at the pressing tape position where the pressing tape part is in contact with the tape to be pasted and the tape to be pasted is pressed on the pole piece and can be used The pressing tape part is separated from the pole piece so that the glue preparation device repositions the adhesive tape to be pasted to the initial position of th...

Abstract

The invention a glue spreading device and glue spreading equipment. A pressing adhesive tape piece is driven to perform a reciprocating motion between the position of a pressing adhesive tape and an initial position through a glue spreading power assembly; the pressing adhesive tape piece is contacted with a pole piece and an adhesive tape wire to be subjected to glue spread, at least partially of which is attached on the pole piece, at the position of the pressing adhesive tape; the pressing adhesive tape piece presses one end of the adhesive tape wire to be subjected to glue spread, and gradually moves to the other end of the adhesive tape wire to be subjected to glue spread at an extrusion state along with the movement of the pole piece; air between the glue tape and the pole piece is extruded out, so that air bubbles and wrinkles can be effectively prevented.

Description

technical field [0001] The present application relates to a device for applying adhesive tape, in particular to a device and equipment for applying adhesive tape to pole pieces during the lithium battery manufacturing process. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In the production process of the battery pole piece in the existing lithium battery industry, it is necessary to stick protective tape to the coating edge of the pole piece and the welding tab. [0003] The existing gluing method is two flat suction cups. Because the suction cups are not completely parallel to the pole piece, part of the air is sealed between the tape and the pole piece during the gluing process, forming air bubbles and wrinkles, which affects the quality of the battery. Contents of the invention [0004] The present application provides a gluing d...
