Problems solved by technology

[0003] However, most of the current battery wrapping machines use a turntable structure, which takes up a lot of space; the wrapping, bending, hot-melting, and wrapping of the insulating film are completed at different stations, which is prone to problems such as unsmooth connection between upstream and downstream processes.

Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing:

[0042] Such as figure 1 Shown is a schematic diagram of the structure of the insulating film 1, in which a positioning hole 1-1 is opened at the middle connection.

[0043] Such as figure 2 Shown is a schematic structural view of the battery cell 2 coated with incoming material, and the tabs of the battery body 2-1 are welded together with the cover plate 2-2.

[0044] Such as image 3 Shown is a schematic diagram of the structure of the battery core after hot-melt coating. The insulating film 1 is coated on the outside of the battery core 2. After hot-melting, a hot-melt welding mark 1-2 is formed on the cover plate 2-2. The insulating film 1 The two sides are fixed by adhesive tape 3.

[0045] Such as Figure 4 As shown, a lithium battery cell outer membrane hot-melt mechanism includes a cell feeding mechanism 5 and a discharging mechanism 9 arranged in a straight l...

Abstract

The invention provides a lithium battery cell outer membrane hot melting mechanism. The lithium battery cell outer membrane hot melting mechanism comprises a battery cell loading mechanism and a unloading mechanism arranged in a straight line, a mechanical arm used for grabbing and releasing battery cells, an insulating membrane loading mechanism and a holt melting membrane coating mechanism which are symmetrically arranged on the two sides of a battery cell loading mechanism discharging end, a top pushing gas cylinder arranged right above the hole melting membrane coating mechanism, and an encapsulating mechanism symmetrically arranged on the two sides of a feed inlet end of the unloading mechanism. The lithium battery cell outer membrane hot melting mechanism is capable of completing insulating membrane loading, battery cell loading, insulating membrane bending and packaging, insulating membrane and cover plate part hot melting, insulating membrane encapsulating, and membrane coated battery cell unloading automatically, realizing simultaneous operation of insulating membrane hot melting and encapsulating, and increasing membrane coating efficiency of battery cell insulating membrane effectively.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery production, in particular to a hot-melt mechanism for the outer film of a lithium battery cell. Background technique [0002] The manufacturing process of lithium-ion batteries is mostly to glue the two batteries, and then weld their tabs on the cover assembly, and then wrap the insulating film around the batteries and heat-melt them with the cover assembly, so as to fix them. Battery cells, prevent subsequent scratches into the case, etc. [0003] However, most of the current battery wrapping machines use a turntable structure, which takes up a lot of space; the wrapping, bending, hot-melting, and gluing of the insulating film are completed at different stations, which is prone to problems such as unsmooth connection between upstream and downstream processes. Therefore, there is a great need for a device that can overcome the above-mentioned defects and improve labor productivity. ...
