In this embodiment, a protruding rib 251 is disposed on the bottom surface of the cover plate assembly 25, and when the cover plate assembly 25 is matched and covered with the cast-weld mold 30, the protruding rib 251 can be matched and embedded into the forming concave channel 301 to seal it individually, thereby improving the lead slag isolation effect. It should be noted that the width of the protruding rib 251 is slightly smaller than the width of the forming concave channel 301, and the protruding rib 251 can be just matched with and embedded into the forming concave channel 301; in addition, the protruding rib 251 has a certain thickness and the thickness of the protruding rib 251 is smaller than the depth of the forming concave channel 301, when the forming concave channel 301 is filled with the lead liquid, the cover plate assembly 25 covers the cast-weld mold 30, and the protruding rib 251 can press out a part of the lead liquid in the forming concave channel 301, so that the amount of the lead liquid stored in the forming concave channel 301 is controlled, and the influence on the cast-weld forming quality due to the fact that the stored lead liquid is over-full is avoided.

Preferably, as shown in fig. 6, a drain channel 252 is further provided on the top surface of the cap assembly 25.

In this embodiment, the liquid drainage channel 252 includes a liquid drainage groove and a liquid drainage opening disposed at one side of the liquid drainage groove, so as to quickly drain the excessive lead liquid, and prevent the excessive lead liquid on the cover plate assembly 25 from flowing onto the cast welding mold 30 to affect the cast welding molding quality in the process of separating the cast welding mold 30 from the cover plate assembly 25.

In a preferred embodiment, the bottom surface of the drainage groove is inclined downward toward the drainage opening, so that the excessive lead liquid is guided to be quickly drained.

The working process is as follows:

the battery pack 101 is conveyed on the conveying unit 41 and abutted against the positioning part 433, after the jacking unit 42 jacks up the variable pitch unit 43 to receive the battery pack 101, the variable pitch driving part 432 drives each supporting part 4311 and each storage battery 102 thereon to be equally separated, the battery packs 101 which are equally distributed are clamped and overturned to a corresponding bearing position 12 by the feeding manipulator 5, soldering flux is adhered to a pole group at the bottom of the storage battery 102 at the position, the battery packs are carried to the cast-weld station 202 by rotating 90 degrees by the station switching unit 40, the pressing mechanism 1 descends to press the top of the battery pack 101, one group of cast-weld molds 30 completes lead dipping at the corresponding lead dipping unit 20 and is driven by the positioning slide carriage 52 to be transferred to the cast-weld unit 10 at the same time of the station switching, the jacking assembly 31 drives the cooling circulation assembly 32 and the cast-weld molds 30 to jack up until the lead liquid in the cast-weld molds 30 is contacted with the pole group at the bottom of the battery packs 101, at this time, the cast-weld mold 30 is cooled by the cooling water in the box 321 to complete cast-weld, the station switching unit 40 carries the cast-weld storage battery pack 101 to the blanking station 203 after rotating for 90 degrees, the storage battery pack is turned to the positive state by the blanking manipulator 7 and is placed on the output mechanism 6, and the storage battery pack is continuously transmitted and output after entering the groove.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
