The connecting rod 1.6 passes through the compression spring 1.4 and is connected to the guide sleeve 1.5 and the push plate 1.3. The push plate 1.3 is connected to the module positioning plate 1.1 through the guide column 1.8. The linear bearing 1.2 is fixed on the fixed seat 1.10.

[0035] like Figure 4 As shown, the module clamping mechanism 2 includes a clamping block 2.1, a connecting plate 2.2 and a lifting cylinder 2.3.

[0036] The connecting plate 2.2 is fixed on the lifting cylinder 2.3, the clamping block 2.1 is fixed on the connecting plate 2.2, and the clamping block 2.1 is tangent to the cam follower 1.11.

The function of the indexing mechanism 5 is to transfer the battery shell 10 to the next station, and the battery shells 10 of multiple stations can be welded at the same time through indexing.

[0040] The operation process of the sealing sheet welding device is as follows:

[0041] Step 1: At the loading station, the lifting cylinder 2.3 moves upward, driving the connecting plate 2.2 and the clamping block 2.3 to move upward, pushing open the cam follower 1.11, and then driving the push plate 1.3 to move backward, and driving the guide column 1.8 and the module positioning plate 1.1 to move backward, thereby achieving the clamping of the battery module.

[0045] Step 5: The sealing sheet welding machine 4 welds the battery module to which the sealing sheet needs to be welded. There are a total of 4 welding stations that can weld the battery modules on the indexing mechanism 5 at the same time.

[0046] Step 6: After welding is completed, the cylinder 3.8 drives the slider mounting seat 3.4 to move forward, and the cam follower 3.3 drives the lifting block 3.2 and the pressure block 3.1 to descend during the forward movement, so as to separate the pressure block 3.1 from the dividing plate.

[0047] Step 7: The indexing mechanism 5 rotates to the next station and repeats the action of step 6 in sequence to complete the welding of the four sealing sheets. When the indexing mechanism 5 rotates to the unloading station, the module clamping mechanism 2 opens the clamp and unloads the materials in sequence.
