Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 and fig. 2, in a preferred embodiment, the laser welding jig of the present invention mainly includes a base 1 and a cover plate 2, wherein the cover plate 2 is detachably connected to the base 1. The surface of the seat body 1 is provided with rows of positioning grooves 3, the positioning grooves 3 are formed into a cylindrical shape, and the positioning grooves 3 are used for fixing batteries. In this embodiment, the seat body 1 is provided with two rows of positioning slots 3, but not limited thereto, in other embodiments, three or more rows of positioning slots 3 may be provided on the seat body 1. A plurality of positioning columns 4 are arranged near each row of positioning grooves 3, the positioning columns 4 vertically extend out of the surface of the seat body 1, and the positioning columns 4 are used for fixing the rows of nickel sheets. In this embodiment, each row of the positioning slots 3 is provided with two positioning posts 4, it should be noted that two ends of the row of the nickel sheets are provided with fixing holes, and when the rows of the nickel sheets are fixed, the positioning posts 4 are inserted into the corresponding fixing holes, so as to fix the row of the nickel sheets.

The cover plate 2 is provided with a plurality of welding guiding holes 5 corresponding to the positioning grooves 3, and the welding guiding holes 5 are used for guiding the laser welding head so as to facilitate welding. In this embodiment, the weld guiding hole 5 is formed in an inverted frustum shape with an upper opening area larger than a lower opening area, so that the laser welding head can be more easily aligned to a position to be welded. When apron 2 lid closes on pedestal 1, lead the lower extreme of welding hole 5 and flush with constant head tank 3 for apron 2 can compress tightly nickel piece and battery, makes the face of weld all at same height, improves the welded precision.

The lower extreme of constant head tank 3 is equipped with the screw hole, and threaded hole is equipped with the bulb plunger 6 that is used for supporting the product, through the height of rotating bulb plunger 6 adjustable bulb plunger 6 to the control supports the size of battery power. It should be noted that the ball plunger 6 may be conventional, and is not described herein.

The surface of the seat body 1 is provided with a positioning bulge 7, the cover plate 2 is provided with a positioning hole 8 corresponding to the positioning bulge 7, and the positioning bulge 7 is matched with the positioning hole 8 to position the cover plate 2.
