How to guarantee the welding quality and the safety and the performance of the battery is a technical subject which needs to be solved urgently.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the invention aims to provide a button cell periphery welding tool.
In order to realize the purpose of the utility model, the utility model provides a button cell periphery welding tool,
comprises a base, a positioning seat, a magnet and an elastic pressing structure,
the positioning seat is arranged on the base, a positioning circular groove is arranged at the upper end of the positioning seat, the shape and the size of the positioning circular groove are matched with those of a battery shell of the button battery for use,
and the middle part of the positioning circular groove is embedded with a magnet for adsorbing the battery shell and the battery cover.
Wherein the front and the back of the positioning circular groove are both opened,
and the height of the magnet is slightly lower than the mounting surface of the positioning circular groove.
The elastic pressing structure comprises a pressing head, an elastic structure and an installation block, and the pressing head is connected with the installation block through the elastic structure.
Wherein, the pressure head adopts the brass material.
Compared with the prior art, the beneficial effects of the utility model are that, during the operation of peripheral laser welding, the operator will treat to weld battery case and battery cover and put into the positioning circular slot after adjusting well, magnet firmly holds them this moment, utilize elasticity to press down the structure and push down, the pressure head compresses tightly the battery cover through elasticity, airtight seamless between battery cover and the battery case this moment, prevent that laser from seeing through the burn battery diaphragm, start laser welding, whole structure rotates a week round the axle center, peripheral laser welding is accomplished, the pressure head, elasticity is pressed down the structure and is risen, loosen the battery, the staff takes out the battery that has welded, weld a battery down once more, so reciprocal, the operation is simple, convenient, the effect is better.
Drawings
FIG. 1 is a schematic structural diagram of the present application;
in the figure, the base 1, the positioning seat 3, the magnet 4, the battery shell 5, the battery cover 6, the pressure head 7, the elastic structure 8 and the mounting block are arranged.
Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in figure 1 of the drawings, in which,
the embodiment of the utility model provides a button cell periphery welding tool,
comprises a base 1, a positioning seat 2, a magnet 3 and an elastic pressing structure,
the positioning seat 2 is arranged on the base 1, the upper end of the positioning seat 2 is provided with a positioning circular groove, the shape and the size of the positioning circular groove are matched with the shape and the size of a battery shell 4 of the button battery for use,
and the middle part of the positioning circular groove is embedded with a magnet 3 for adsorbing the battery shell 4 and the battery cover 5.
It should be noted that the size of the positioning circular groove is just larger than that of the battery case 4, so that the battery case 4 is conveniently positioned, and the front and the back of the circular groove are provided with openings, so that the battery is conveniently taken and placed by hands.
It should be noted that the magnet 3 is embedded in the middle of the positioning circular groove, and the height of the magnet 3 is slightly lower than the mounting surface, so that the battery case 4 and the battery cover 5 are tightly attracted, and the battery case 4 and the battery cover 5 are prevented from moving when the tooling switching station rotates.
It should be noted that the pressure head 6 is made of brass, so that heat dissipation is facilitated, the center of the pressure head 6 is hollowed, and the contact part of the pressure head and the battery cover 5 is chamfered, so that the battery is compacted conveniently.
