Lithium battery positive electrode series welding equipment and its fixed-angle transmission welding process

Abstract

The invention relates to lithium battery anode series-connection welding equipment and a fixed-angle conveying welding process thereof. The equipment comprises a supporting bottom plate, a conveying device and a welding device; a sliding groove is formed in the top of the right end of the supporting bottom plate; the conveying device is mounted at the top of the left end of the supporting bottom plate; the welding device is mounted at the top of the right end of the supporting bottom plate; and the welding device comprises a welding supporting plate, a fixed push rod, a welding position push rod, a sliding connecting frame, a welding height push rod and a welding mechanism. By means of the lithium battery anode series-connection welding equipment and the fixed-angle conveying welding process thereof, the problems that in the prior art, during lithium battery welding, manual conveying and straightening of welding tin wires are needed, the hidden danger of breaking the welding tin wireswhen the welding tin wires are pulled exists, position change is prone to occurring when the welding tin wires are taken manually, fixing is not allowed when a lithium battery is welded, and a weldinggun tends to shaking when being held manually can be solved; and the functions of positioning conveying of the welding tin wires and automatic adjustment of the lithium battery welding angle can be achieved during lithium battery welding.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a lithium battery cathode series welding equipment and a fixed-angle transmission welding process thereof. Background technique [0002] Batteries are divided into many types, among which lithium batteries are the most widely used in existing batteries. Lithium-ion batteries have the advantages of light weight, large capacity, and no memory effect, so they have been widely used. Many digital devices have adopted Lithium-ion battery is used as a power source, although its price is relatively expensive; the energy density of lithium-ion battery is very high, its capacity is about twice that of Ni-MH battery of the same weight, and it has a very low self-discharge rate. In addition, Lithium-ion batteries have almost no "memory effect" and no toxic substances, which are also important reasons for their wide application. [0003] Generally, the series welding of household lithium b...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a lithium battery positive electrode series welding equipment and its fixed-angle transmission welding process, which can solve the existing need to manually transmit the solder wire and manually straighten the solder wire when welding the lithium battery. Action, the hidden danger of the solder wire being pulled when pulled, the position of the manual holding the solder wire is prone to change, the lithium battery cannot be fixed during welding, and the welding torch will shake when manually holding it; it can be realized when welding the lithium battery The function of positioning and transmitting the solder wire and automatically adjusting the welding angle of the lithium battery has the function of automatically transmitting the solder wire, automatically straightening the solder wire, and there is no hidden danger of the solder wire being broken when it is pulled, and the mechanized transmission of the solder wire will not happen The position changes, the lithium battery can be fixed during welding, and the mechanized clamping welding torch will not shake, etc.
