In an embodiment of the present utility model, a dual-station tab cap welding mechanism 100 is provided for welding a tab and a cap of a cylindrical cell. As shown in fig. 1, the cylindrical battery cell is fixed on the fixture 200, and the cap is fed by the cap feeding mechanism 300.

As shown in fig. 1 to 3, the double-station tab cap welding mechanism 100 includes a fixing frame 10 and two spot welding assemblies 20 provided on the fixing frame 10.

The fixing frame 10 includes a bottom plate 11, a top plate 12, and a plurality of support rods 13 connecting the bottom plate 11 and the top plate 12, thereby forming a rectangular frame structure.

Specifically, each spot welding assembly 20 includes a horizontal pushing cylinder 21 and a horizontal plate 22, and the horizontal pushing cylinder 21 is fixed to the fixing frame 10 and is used for driving the horizontal plate 22 to move. Wherein, the fixed end of the horizontal pushing cylinder 21 is fixed on the top plate 12 through a connecting sleeve 23.

Further, the top plate 12 is provided with a sliding rail 14, the bottom of the horizontal plate 22 is provided with a sliding block 15, the sliding block 15 is provided with a sliding groove (not shown in the figure) matched with the sliding rail 14, and the horizontal plate 22 can reciprocate on the top plate 12 through the sliding block 15, so that the moving direction of the horizontal plate 22 on the top plate 12 is limited through the action of the sliding groove and the sliding rail 14.

Further, the horizontal plate 22 is further provided with a limiting seat 24. The top plate 12 is further provided with a buffer seat 16 at a position between the two horizontal plates 22, and two ends of the buffer seat 16 extend to the positions above the two horizontal plates 22 respectively and are provided with a buffer 17. The specific structure and implementation principle of the buffer 17 can refer to the prior art, and the present utility model is not described herein. The buffer 17 is used for abutting against the limiting seat 24 to buffer the movement of the horizontal plate 22 on the top plate 12, so as to avoid excessive impact stress caused by the movement of the horizontal plate 22.

In the embodiment of the utility model, the vertical plates 25 are vertically arranged on the sides, far away from each other, of the two horizontal plates 22, the vertical plates 25 are provided with welding blocks 30, welding pins 31 are arranged on the welding blocks 30, and one ends of the welding pins 31 extend out of the vertical plates 25, so that the lug caps on the jig 200 at the preset position are welded.

Therefore, when the screw rod 252 rotates, the driving block 253 can move relative to the screw rod 252 through the action modes such as the threaded action of the screw rod 252 and the driving block 253. The welding block 30 is connected to the driving block 253 through a guide rod 32. That is, the screw rod 252 can be rotated to finely adjust the position of the welding block 30, so that the welding spot of the welding pin 31 is at the most suitable position to adapt to the jigs with different models and fixing modes.

Wherein, the vertical plate 25 is also vertically provided with a support plate 254, and the support plate 254 can be multiplexed with the screw rod seat 251.

Further, the vertical plate 25 is further provided with a first stop block 256 and a second stop block 257 respectively disposed on two sides of the driving block 253, and the first stop block 256 and the second stop block 257 are used for limiting the front and rear end moving positions of the driving block 253 on the screw rod 252 respectively, that is, the movement of the welding block 30 and the welding needle 31 is correspondingly limited.

Further, the number of the guide rods 32 is two, and the guide rods are all arranged on the driving block 253 in a penetrating manner; the two guide rods 32 are respectively arranged at two sides of the screw rod 252 at intervals. Therefore, the movement of the driving block 253 on the screw 252 is restricted by the co-action of the two guide bars 32, and the driving block 253 is prevented from rotating with the rotation of the screw 252, so that only the movement component of the driving block 253 moving along the screw 252 remains.

In summary, according to the double-station tab cap welding mechanism 100 provided by the utility model, two spot welding assemblies 20 are simultaneously arranged on the fixing frame 10, so that two tabs and caps can be welded simultaneously, and the welding efficiency is doubled; and the horizontal plate 22 is driven to move through the horizontal pushing cylinder 21, so that the welding needle 31 can be close to the lug cap and welded, the whole structure is simpler, and the processing cost is correspondingly reduced.

The present utility model is not limited to the details and embodiments described herein, and thus additional advantages and modifications may readily be made by those skilled in the art, without departing from the spirit and scope of the general concepts defined in the claims and the equivalents thereof, and the utility model is not limited to the specific details, representative apparatus and illustrative examples shown and described herein.
