Description

Technical Field

[0001] The utility model relates to the field of lithium batteries, in particular to a lithium battery cap pressure welding device. Background Art

[0002] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. Lithium batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy as the negative electrode material, and use a non-aqueous electrolyte solution.

[0003] Currently, after the production of lithium batteries, a pressure cap needs to be assembled at the conductor part of the lithium battery for charging or discharging the lithium battery. The existing pressure cap welding uses a person to hold a welding gun to perform spot welding on the pressure cap on the lithium battery, and the efficiency is not high.

[0004] However, for a traditional lithium battery cap pressure welding device on the market currently, its structure is not optimized enough and the design is not reasonable enough. Content of the Utility Model

[0005] The purpose of the utility model is to provide a lithium battery cap pressure welding device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lithium battery cap pressure welding device includes a workbench and a clamping member. A slide rail is fixedly connected to the top of the workbench. A substrate is slidably connected to the surface of the clamping member. A push rod is installed at the side part of the lower surface of the substrate. An electric push rod is installed at the pushing end of the push rod. A lithium battery frame is installed on the upper surface of the substrate. A bracket is fixedly connected to the rear part of the upper surface of the workbench. A screw rod transmission mechanism one is fixedly connected to the top of the bracket. A screw rod transmission mechanism two is installed at the displacement end of the screw rod transmission mechanism one. A motor is installed at the driving end of the screw rod transmission mechanism two. A welding wire cylinder is installed on the left side of the front vertical surface of the bracket.

[0008] As a further scheme of the utility model: A connecting block is fixedly connected to the bottom of the screw rod transmission mechanism two. A connecting piece is fixedly connected to the bottom of the connecting block. An arc groove is formed at the outer part of the upper surface of the connecting piece.

[0009] As a further scheme of the utility model: A clamping member is fixedly connected to the bottom of the arc groove. A connecting member is installed at the clamping part of the clamping member. A vertical piece is fixedly connected to the bottom of the connecting member.

[0011] As a further solution of the present utility model: A welding torch is installed at the rear part of the bottom of the connecting piece.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In this practical utility model, when the screw rod transmission mechanism one operates, it drives the screw rod transmission mechanism two to move left and right. Then, control the motor at the driving end of the screw rod transmission mechanism two to operate, which drives the connecting block connected to the displacement end of the screw rod transmission mechanism two to move back and forth. The connecting piece and the connecting components connected to the bottom of the connecting block will all move back and forth. The welding torch installed at the bottom of the connecting piece is in a fixed state. The arc groove opened at the front end of the upper surface of the connecting piece is used to perform arc rotation on the clamping piece in the notch, and drives the connecting piece clamped on the clamping piece, the vertical piece connected to the connecting piece, and the pipe passing through connected to the vertical piece to swing as a whole, so that the pipe rotates circumferentially around the bottom of the welding torch, which is used for cap spot welding of the connecting part of the lithium battery in the lithium battery frame placed on the substrate. Its structure is more optimized and the design is more reasonable. Description of the Drawings
