[0002] At present, when assembling new energy battery covers on the market, the base plate, pole, sealing ring, welding ring and other components are basically grabbed and placed on the assembly table one by one in the order of assembling parts. In this process, since the sealing ring is made of soft rubber material, it is very easy to deform during the installation process. Therefore, the assembly deviation of the sealing ring and the pole is the most frequent problem in the assembly process and also the difficulty in the assembly; once the assembly deviation of the sealing ring and the pole occurs, the subsequent assembly process will not be able to proceed, and it can only be discharged and disposed of, which has a great impact on the product production capacity.

Second, the preassembled pole is pressed by the rotating pressing unit, so that the assembly can be reliably transported to the next assembly station, which ensures the assembly quality of the assembly and other parts, thereby improving the overall assembly quality and assembly efficiency of the new energy battery cover.

[0030] When the new energy battery cover plate of the present invention is assembled: while placing the sealing ring 5 on the sealing ring clamping carrier 1, the pole picking carrier 2 grabs the pole 6 at the work station; when the sealing ring clamping carrier 1 moves with the sealing ring 5 along the linear module 3 to the bottom of the gantry assembly 4, the pole picking carrier 2 moves with the pole 6 through the gantry assembly 4 to the top of the sealing ring clamping carrier 1, and the pole 6 is placed in the sealing ring clamping carrier 2 through the pole picking carrier 2, thereby realizing the pre-assembly of the sealing ring 5 and the pole 6.

[0031] The present invention pre-assembles the pole made of hard material to provide an internal skeleton for the sealing ring to prevent the sealing ring from deforming, and then performs overall assembly, thereby solving the problem of easy deformation of the sealing ring during the assembly of the cover plate. Without reducing the production efficiency, the stability of high-precision assembly of the sealing ring, a soft material, is effectively improved, the qualified rate of assembly is guaranteed, and the production efficiency is further improved.

[0032] Example 2

[0033] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be known that the pre-assembly mechanism of the present invention: the sealing ring clamping carrier includes multiple sealing ring clamping assemblies, each sealing ring clamping assembly includes a connecting plate 11 and two clamping units, each clamping unit includes a clamping cylinder 12 and multiple tensioning blocks 13; the bottom of the connecting plate 11 is connected to the track, the clamping cylinder 12 is fixed on the top of the connecting plate 11, and each clamping jaw of the clamping cylinder 12 is connected to a tensioning block 13.

[0034] The clamping jaw cylinder 12 first drives the multiple tensioning blocks 13 to be in a retracted state, and then places the sealing ring 5 on the tensioning blocks 13. The clamping jaw cylinder 12 then drives the multiple tensioning blocks 13 to open outward, and the tensioning blocks 13 tighten and position the inner ring of the sealing ring 5 to keep it from deforming during transportation.

[0035] Example 3

[0037] When the clamping jaw cylinder 12 drives the multiple tensioning blocks 13 to be in a retracted state, the lower end surface of the sealing ring 5 contacts the positioning portion 132; the clamping jaw cylinder 12 drives the multiple tensioning blocks 13 to open outward, and the tensioning portion 133 tightens and positions the inner ring at the bottom of the sealing ring 5 to keep it from deforming during transportation.

[0038] Example 4

[0040] When the clamping jaw cylinder 12 drives the plurality of tensioning blocks 13 to open outward, the limiting sleeve 14 limits the outside of the tensioning block 13 to ensure the opening angle of the tensioning block 13 to avoid damaging the sealing ring 5.

[0041] Example 5

[0042] from Figure 1 , Figure 2 , Figure 3 It can be known that the pre-assembly mechanism of the present invention: the gantry assembly 4 includes two support seats 41, a crossbeam 42, a transverse module 43, and a height module 44; the two support seats 41 are respectively located at the front and rear ends of the module 2, the front and rear ends of the crossbeam 42 are respectively connected to the guide rails on the upper parts of the left and right support seats 41 through the lower slider, the transverse module 43 is fixed on the side of the crossbeam 22, the height module 44 is connected to the transverse module 43, and the pole material picking carrier 2 is connected to the height module 44.

[0043] The pole picking carrier 2 realizes movement in three directions of XYZ through the crossbeam 42, the transverse module 43 and the height module 24 to realize the limited release of the pole: when the sealing ring clamping carrier 1 stops moving when it comes to the bottom of the crossbeam 41 through the linear module 3, the pole picking carrier 2 that grabs the pole at the upper pole grabbing station comes to the top of the sealing ring clamping carrier 1 through the transverse module 23, and then places the pole 6 on the sealing ring 5.

[0044] Example 6

[0046] When the pole picking carrier 2 arrives at the pole grabbing station, the clamping claw cylinder 22 drives the clamping claw 23 to grab the pole 6; then it arrives above the sealing ring clamping carrier 1, and the connecting block 21 moves downward along the height module 44 to put the lower part of the pole 6 into the inner ring of the upper part of the sealing ring 5, thereby realizing the pre-assembly of the pole 6 and the sealing ring 5. Fig.11 As shown, the pole 6 made of a hard material provides an internal skeleton for the sealing ring 5 to prevent the sealing ring 5 from deforming, thereby solving the problem of the sealing ring being easily deformed during the assembly of the cover plate.

[0047] Example 7

[0048] from Figure 1 , Figure 2 , Figure 3 , Figure 8 It can be seen that in the pre-assembly mechanism of the present invention: the upper end of the clamping jaw 23 is connected to the clamping jaw cylinder 22, the middle is hinged to the telescopic part of the cylinder, and the lower end is a free end.

[0049] When the clamping jaw cylinder 22 works, its telescopic rod extends to push the free end of the clamping jaw 23 to open, grab the pole 6 from the outer circle of the pole, and then retracts to achieve clamping; when the pole 6 is assembled with the sealing ring 5, the telescopic rod of the clamping jaw cylinder 22 extends to push the free end of the clamping jaw 23 to open, thereby releasing the pole 6.

[0050] from Fig. 9 , Fig.10 It can be seen that the pre-assembly mechanism of the sealing ring and the pole of the present invention is as follows: the upper end of the clamping jaw 23 is embedded in the clamping jaw cylinder 22 through the annular connecting portion 231, and the lower end thereof is provided with a stepped clamping portion 232.

[0058] When the pole 6 is not placed, the clamping rod 16 is vertical to the center line of the two clamping units; when the pole 6 is placed on the sealing ring 5, the rotary cylinder 15 works, and its rod end moves upward with the clamping rod 16 and then rotates accordingly. When the clamping rod 16 coincides with the center line of the two clamping units, the rod end of the rotary cylinder 15 moves down with the clamping rod 16, so that the two ends of the clamping rod 16 are pressed on the pole 6 to prevent the pole 6 from falling during transportation to the next workstation.
