Technical Field
The utility model relates to the field of lithium battery production and processing, in particular to a lithium battery cover plate welding device.
Background
A lithium battery is a type of battery using a nonaqueous electrolyte solution, using lithium metal or a lithium alloy as a positive/negative electrode material. Lithium metal batteries were first proposed and studied by Gilbert n. Lewis in 1912. In the 70 s of the 20 th century, m.s. Whittingham proposed and began to study lithium ion batteries. Because the chemical characteristics of lithium metal are very active, the requirements on the environment for processing, storing and using the lithium metal are very high. With the development of scientific technology, lithium batteries have become the mainstream.
In the course of working of lithium cell, need weld the apron on the lithium cell, current welding set generally adopts laser welding to fix the welding rifle to the location in order to realize in the space on the triaxial guide rail, with adjustment welding position, however this kind of device not only needs a plurality of motors with the adjustment position, and the cost is higher and the welding precision is difficult to guarantee moreover.
Disclosure of Invention
The utility model provides a lithium battery cover plate welding device aiming at the problems of the existing lithium battery cover plate welding device, which structurally comprises: the welding gun of the laser welding machine is fixed on the lifting structure; the processing turntable is driven by a driving motor to rotate, a plurality of rectangular grooves are formed in the upper surface of the processing turntable, and each groove is provided with a lithium battery fixing box; each of the grooves is rotatable to below the welding gun.
Preferably, the lithium battery fixing box comprises an inner cavity for fixing the lithium battery, a protruding guide post is arranged at one corner of the outer bottom of the lithium battery fixing box, the guide post is a cube, and the bottom of the guide post is a square.
Preferably, the width of the groove is equal to the length of the bottom side of the guide pillar.
Preferably, when the guide post moves around the groove for one circle, the welding gun head moves around the upper part of the lithium battery fixing box for one circle.
Preferably, the lithium battery fixing box is made of metal or graphite.
When the lithium battery welding machine is used, a lithium battery to be processed is placed in the lithium battery fixing box, the lithium battery to be processed is rotated to the position below the welding gun, the welding gun is lowered for welding, the lithium battery fixing box is operated for a circle around the groove by holding the lithium battery fixing box by hand, the upper lithium battery cover plate and the edge of the shell are welded for a circle by the welding gun, the welding process is stable and accurate, the welding can be completed only by lifting the welding gun, and the cost is saved.
