[0002] The structure of a lead-acid battery includes a battery slot and a pole group arranged in the battery slot. The pole group includes alternating stacked positive and negative plates. The positive tabs of all positive plates in the same pole group need to be connected in series using a positive bus bar, and the negative tabs of all negative plates in the same pole group need to be connected in series using a negative bus bar. At the same time, the positive and negative bus bars need to be connected in series between adjacent pole groups. The formation of the bus bar is generally completed by cast welding.

[0003] Chinese patent publication number CN111069573A proposes a battery casting welding device that can automatically process scum on the surface of molten lead to ensure that the casting welding bottom mold does not allow scum to enter the mold cavity during the casting welding process. However, it has some problems: 1. The casting welding bottom mold cannot play a role in shaping the electrode group formed by welding; 2. When the electrode group is welded, when the electrode group comes into contact with the lead liquid, it will stimulate the lead liquid to form heavy metal vapor, which is harmful to the health of the operator.

A mounting seat 302 is integrally formed on the side of the trimming and forming template 301. The mounting seat 302 is provided with a mounting hole 303. The trimming and forming template 301 is detachably mounted on the lead pool 101 by fixing screws. The trimming and forming template 301 can restrain the pole group when the cylinder 102 drives the pole group to move downward, preventing the pole group from expanding outward. The trimming and forming template 301 covers the four sides of the lead pool 101, which can reduce the outward diffusion of lead vapor. Sixteen groups of trimming and forming grooves 304 arranged in an equidistant array are provided on the trimming and forming template 301, and the trimming and forming grooves 304 are arranged in a square structure. The outer side of the lower part of the trimming and forming grooves 304 is integrally formed with a ring-shaped trimming blade 305. After the pole group is welded, the cylinder 102 drives the pole group to move upward, and the excess lead material around the pole group will be cut and trimmed by the trimming blade 305. The excess lead material falls into the lead pool 101 and is re-melted. The trimming blade 305 of the trimming and forming template 301 can be quickly disassembled and replaced by screws after the blade becomes blunt due to long-term use.

[0024] The battery casting welding machine includes a casting table body 1, a lead pool 101 is installed on the upper end of the casting table body 1, and a trimming and forming template 301 is detachably installed on the lead pool 101 by fixing screws.

The two ends of the spring 209 are welded to the top of the limit slide 220 and the upper end of the limit slide 221 respectively. The conveying grooves 219 facilitate the assembly personnel to install the assembled pole group to the lower part of the cylinder 102 for welding; Working principle: First, you need to place the fixed plate 201 upright on a stable plane, then turn the knob 218 to move the support 207 outward to make way for the installation of the pole group, and then install the pole group between the pole group baffle 204 and the top plate 205. After installation, rotate the knob 218 to move the support 207 inward to support the top plate 205, clamping the pole group, and then use the transport slot 219 to transport the fixed plate 201 and invert the fixed plate 201, and then insert the card column 109 on the card strip 108 into the card hole 211 in the card slot 210 to fix it, and then control the cylinder 102 to move down for welding and cutting and shaping. After the pole group cools down, move the lower fixed plate 201 and the pole group above, and rotate the knob 218 to complete the disassembly.
