[0040] Figure 1 It is a structural schematic diagram of an embodiment of the end plate mounting device of the utility model; Figure 2 This is a structural schematic diagram of an embodiment of the end plate installation device of the utility model when clamping the end plate; Figure 3 It is a structural schematic diagram of another angle of an embodiment of the end plate mounting device of the utility model; Figure 4 It is a bottom view schematic diagram of an embodiment of the end plate mounting device of the utility model; Figure 5 The end plate installation device of the utility model is a structural schematic diagram from another angle. In the utility model embodiment, the end plate installation device comprises: a first drive assembly 100, a second drive assembly 200, a mounting platform 300, a mounting plate 400 and a rack assembly.

[0041] The first driving assembly 100 is arranged on the mounting platform 300, and the second driving assembly 200 is arranged on one side of the mounting platform 300. The second driving assembly 200 is arranged to drive the mounting platform 300 to move along the first direction X. The mounting plate 400 is movably connected with the mounting platform 300, and the mounting plate 400 is arranged to reciprocate relative to the mounting platform 300 along the second direction Y, so that the mounting plate 400 can abut against the end plate 1000 and install the end plate 1000 on the battery cell when it is away from the mounting platform 300. The clamping assembly 500 is arranged on both sides of the mounting plate 400 and is in transmission connection with the first driving assembly 100. The first driving assembly 100 can drive the clamping assembly 500 to approach or move away from the end plate 1000, so that the end plate 1000 is clamped by the clamping assembly 500 or detached from the clamping assembly 500.

[0042] In the embodiment of the utility model, the first driving assembly 100 can drive the installation platform 300 to move along the first direction X, the second driving assembly 200 can drive the clamping assembly 500 to clamp the end plate 1000, and the installation plate 400 is movably connected to the installation platform 300 and can reciprocate along the second direction Y.

[0043] After the end plate 1000 is clamped by the clamping assembly 500, the mounting plate 400 moves away from the mounting platform 300, so that the surface of the mounting plate 400 abuts against the surface of the end plate 1000. The mounting plate 400 pushes the end plate 1000 away from the mounting platform 300, so that the surface of the end plate 1000 abuts against the surface of the battery cell and the end plate 1000 is mounted on the battery cell.

[0044] After the end plate 1000 is installed, the mounting plate 400 moves towards the mounting platform 300 to reset, for installing the next end plate 1000 on the battery cell. Wherein, the first direction X of this embodiment is the direction perpendicular to the ground, that is, the first driving assembly 100 drives the mounting platform 300 to move up and down relative to the ground, and the second direction Y is the direction parallel to the horizontal plane.

[0045] Furthermore, both sides of the mounting plate 400 are connected to the mounting platform 300 through connecting shafts, and the connecting shafts pass through the mounting platform 300 to realize the movable connection between the mounting plate 400 and the mounting platform 300. When the mounting plate 400 reciprocates along the second direction Y, the connecting shafts reciprocate along the second direction Y together with the mounting plate 400.

[0046] The end plate mounting device of the embodiment of the present utility model can drive the mounting platform 300 to move to a suitable position through the second driving assembly 200, and then drive the clamping assembly 500 to clamp the end plate 1000 through the first driving assembly 100, so that the mounting plate 400 can push the end plate 1000 towards the battery cell. The end plate mounting device of the embodiment of the present utility model clamps the end plate 1000 through the clamping assembly 500, and then pushes the clamped end plate 1000 towards the battery cell core through the mounting plate 400, realizing the stable connection between the end plate 1000 and the battery cell.

[0047] In some embodiments, the clamping assembly 500 includes a first clamping member 510 and a second clamping member 520. The first clamping member 510 and the second clamping member 520 are arranged oppositely, and the first driving assembly 100 is configured to drive the first clamping member 510 and the second clamping member 520 to approach each other, clamp the end plate 1000 between the first clamping member 510 and the second clamping member 520, so that the surface of the end plate 1000 faces the surface of the mounting plate 400.

[0048] Furthermore, the first driving assembly 100 can also drive the first clamping member 510 and the second clamping member 520 to move away from each other, and release the end plate 1000 clamped by the first clamping member 510 and the second clamping member 520.

[0049] In this embodiment, the first clamping member 510 and the second clamping member 520 are arranged at intervals, and the clamping ends of the first clamping member 510 and the second clamping member 520 are opposite to each other. When the first driving assembly 100 drives the first clamping member 510 and the second clamping member 520 to approach each other, the first clamping member 510 and the second clamping member 520 can clamp the end plate 1000 so that the mounting plate 400 can push the end plate 1000 towards the battery cell. After the end plate 1000 is mounted on the battery cell, the first driving member 110 drives the first clamping member 510 and the second clamping member 520 to move away from each other, so that the first clamping member 510 and the second clamping member 520 are disengaged from the end plate 1000.

[0050] In some embodiments, the clamping assembly 500 further includes a transmission assembly 530. The first driving assembly 100 is respectively connected to the first clamping member 510 and the second clamping member 520 through the transmission assembly 530.

[0051] In this embodiment, the first driving assembly 100 drives the first clamping member 510 and the second clamping member 520 respectively through the transmission assembly 530, so that the first clamping member 510 and the second clamping member 520 can approach or move away from each other independently. When the clamping assembly 500 clamps the end plate 1000, by respectively controlling the displacement amounts of the first clamping member 510 and the second clamping member 520, the clamping assembly 500 can clamp end plates 1000 of different lengths, realizing the compatibility with end plates 1000 of different sizes.

[0052] In some embodiments, the transmission assembly 530 includes at least two first connecting members 531 and at least two second connecting members 532. At least two first connecting members 531 are slidably arranged on the surface of the mounting platform 300. One end of the first connecting member 531 is connected to the telescopic end of the first driving assembly 100, and the other end is connected to the corresponding second connecting member 532. At least two second connecting members 532 are respectively connected to the first clamping member 510 and the second clamping member 520, and the second connecting member 532 extends in the direction close to the mounting plate 400.

[0053] In this embodiment, the first clamping member 510 is connected to the first driving assembly 100 through a first connecting member 531 and a second connecting member 532, and the second clamping member 520 is connected to the first driving assembly 100 through another first connecting member 531 and another second connecting member 532, realizing the independent driving of the first driving assembly 100 for the first clamping member 510 and the second clamping member 520.

[0054] In some embodiments, the transmission assembly 530 further includes two elastic members 534, two fixing members 535 and at least two third connecting members 533.

[0055] The third connecting member 533 is connected to the first connecting member 531. The second connecting member 532 passes through the third connecting member 533, and one end of the second connecting member 532 away from the mounting plate 400 is connected to the fixing member 535. The elastic member 534 is sleeved on the second connecting member 532 and is located between the fixing member 535 and the third connecting member 533.

[0056] The elastic member 534 is configured to apply an elastic force to the fixing member 535, so that the second connecting member 532 drives the first clamping member 510 and / or the second clamping member 520 to reset.

[0057] In this embodiment, when the mounting plate 400 moves in a direction away from the mounting platform 300, the elastic member 534 located between the second connecting member 532 and the fixing member 535 will be compressed by the fixing member 535 and the second connecting member 532, so that the elastic member 534 is in an energy storage state. After the mounting plate 400 mounts the end plate 1000 to the battery cell, the elastic member 534 will apply an elastic force to the fixing member 535, so that the fixing member 535 moves away from the second connecting member 532 and applies a force to the mounting plate 400 through the third connecting member 533, causing the mounting plate 400 to move in a direction close to the mounting platform 300.

[0058] At the same time, when the mounting plate 400 reciprocates along the second direction Y, the elastic member 534 can also absorb the impact force generated during the reciprocating movement of the mounting plate 400, playing a buffering role to prevent the impact force generated when the mounting plate 400 is pushed from damaging the end plate 1000 or the battery cell.

[0059] In some embodiments, the first driving assembly 100 includes a first driving member 110 and a second driving member 120, and the mounting platform 300 includes a first fixing plate 310.

[0060] The first fixing plate 310 is configured to reciprocate along the second direction Y. The first driving member 110 and the second driving member 120 are arranged on the first fixing plate 310. The telescopic end of the first driving member 110 is telescopically connected to one end of one first connecting member 531, and the telescopic end of the second driving member 120 is telescopically connected to one end of the other first connecting member 531.

[0061] In this embodiment, the telescopic end of the first driving member 110 is drivingly connected to the first clamping member 510 through one first connecting member 531, one second connecting member 532, and one third connecting member 533. The telescopic end of the second driving member 120 is drivingly connected to the second clamping member 520 through the other first connecting member 531, the other second connecting member 532, and the other third connecting member 533, realizing the independent driving of the first clamping member 510 and the second clamping member 520.

[0062] Two first connecting members 531 are arranged on the surface of the first fixing plate 310. The telescopic ends of the first driving member 110 and the second driving member 120 are arranged away from each other. The telescopic ends of the first driving member 110 and the second driving member 120 drive the corresponding first connecting members 531 to reciprocate along the surface of the first fixing plate 310. When the telescopic ends of the first driving member 110 and the second driving member 120 extend, the two first connecting members 531 move away from each other and drive the first clamping member 510 and the second clamping member 520 to move away from each other. When the telescopic ends of the first driving member 110 and the second driving member 120 retract, the two first connecting members 531 move closer to each other and drive the first clamping member 510 and the second clamping member 520 to move closer to each other.

[0063] In some embodiments, the end plate mounting device further includes a third driving assembly 600, and the mounting platform 300 further includes a second fixing plate 320.

[0064] The second fixing plate 320 is arranged at an interval from the first fixing plate 310. The third driving assembly 600 is arranged on the second fixing plate 320 and is arranged opposite to the mounting plate 400. The third driving assembly 600 is configured to drive the mounting plate 400 to reciprocate along the second direction Y, so that the surface of the mounting plate 400 can abut against the surface of the end plate 1000 clamped by the clamping assembly 500 and push the end plate 1000 to be mounted on the battery cell.

[0065] In this embodiment, when the telescopic end of the third driving assembly 600 extends, it can abut against the mounting plate 400 and push the mounting plate 400 towards the end plate 1000 clamped by the clamping assembly 500, so that the end plate 1000 is pushed towards the battery cell and mounted on the battery cell. After the end plate 1000 is mounted, the telescopic end of the third driving assembly 600 retracts, and the elastic force of the elastic member 534 resets the mounting plate 400.

[0066] In some embodiments, the third driving assembly 600 includes a third driving member 610 and a pushing block 620. The third driving member 610 is arranged on the second fixing plate 320. The pushing block 620 is connected to the telescopic end of the third driving member 610 and is located between the telescopic end of the third driving member 610 and the mounting plate 400.

[0067] In this embodiment, the telescopic end of the third driving member 610 is connected to the pushing block 620. The surface of the pushing block 620 is opposite to the surface of the mounting plate 400 on the side away from the end plate 1000. The pushing block 620 is located between the telescopic end of the third driving member 610 and the mounting plate 400, that is, the telescopic end of the third driving member 610 abuts against the surface of the mounting plate 400 through the pushing block 620.

[0068] The relatively large surface area of the pushing block 620 can reduce the pressure exerted by the third driving member 610 on the mounting plate 400, preventing damage to the mounting plate 400. When the telescopic end of the third driving member 610 extends, it can drive the pushing block 620 to abut against the mounting plate 400 and push the mounting plate 400, enabling the mounting plate 400 to mount the end plate 1000 on the battery cell. When the telescopic end of the third driving member 610 retracts, it can drive the pushing block 620 to separate from the mounting plate 400, enabling the elastic member 534 to reset the mounting plate 400.

[0069] In some embodiments, the end plate mounting device further includes a fourth driving member 700, and the mounting platform 300 further includes a third fixing plate 330.

[0070] The third fixing plate 330 is spaced apart from the first fixing plate 310. The fourth driving member 700 is disposed on the third fixing plate 330 and the telescopic end of the fourth driving member 700 is connected to the first fixing plate 310. The fourth driving member 700 is configured to drive the first fixing plate 310 to reciprocate along the second direction Y.

[0071] In this embodiment, the third fixing plate 330 is located on the side of the first fixing plate 310 away from the mounting plate 400. The telescopic end of the fourth fixing member 535 can drive the first fixing plate 310 to reciprocate along the second direction Y. When the first fixing plate 310 reciprocates along the second direction Y, it can drive the mounting plate 400 to move together, realizing the adjustment of the position of the mounting plate 400, so that the clamping assembly 500 can clamp the end plate 1000.

[0072] The second driving assembly 200 realizes the adjustment of the height of the mounting plate 400 by driving the mounting platform 300 to reciprocate along the first direction X. By adjusting the position of the mounting plate 400 through the third driving member 610, the fourth driving member 700 and the second driving assembly 200, the clamping assembly 500 can accurately clamp the end plate 1000.

[0073] Furthermore, the first driving member 110, the second driving member 120, the third driving member 610, the fourth driving member 700 and the second driving assembly 200 can be cylinders, motors or other driving devices capable of having telescopic ends.

[0074] In some embodiments, the end plate mounting device further includes a first positioning assembly 800 and a second positioning assembly 900, and the mounting platform 300 further includes a fourth fixing plate 340 and a fifth fixing plate 350.

[0075] Two ends of the first fixing plate 310 are respectively slidably disposed on the surfaces of the fourth fixing plate 340 and the fifth fixing plate 350, and two ends of the second fixing plate 320 and the third fixing plate 330 are respectively connected to the surfaces of the fourth fixing plate 340 and the fifth fixing plate 350.

[0076] The telescopic end of the second driving component 200 is connected to one of the fourth fixing plate 340 and the fifth fixing plate 350, and the telescopic end of the second driving component 200 extends in the first direction X, so that the second driving component 200 can drive the mounting platform 300 to reciprocate in the first direction X.

[0077] The first positioning component 800 is slidably arranged on the surface of the fourth fixing plate 340, and the second positioning component 900 is slidably arranged on the surface of the fifth fixing plate 350. The first positioning component 800 has a protruding first limiting portion 810, and the second positioning component 900 has a protruding second limiting portion 910. The first limiting portion 810 and the second limiting portion 910 are arranged to limit the mounting plate 400 to a preset position, so that the clamping component 500 can clamp the end plate 1000.

[0078] In this embodiment, the fourth fixing plate 340 and the fifth fixing plate 350 of the end plate mounting device are respectively slidably arranged on the surfaces of the first fixing seat 1100 and the second fixing seat 1200, and the surfaces of the first fixing seat 1100 and the second fixing seat 1200 are oppositely arranged.

[0079] Furthermore, guide rails are arranged on the surfaces of the fourth fixing plate 340 and the fifth fixing plate 350. The guide rails extend in the second direction Y. Two ends of the third fixing plate 330 are connected to sliders, and the sliders are slidably arranged on the guide rails of the fourth fixing plate 340 and the fifth fixing plate 350, so that the third fixing plate 330 can reciprocate in the second direction Y relative to the fourth fixing plate 340 and the fifth fixing plate 350. When the third fixing plate 330 reciprocates in the second direction Y, it can drive the mounting plate 400 to reciprocate in the second direction Y together, realizing the adjustment of the position of the mounting plate 400, and facilitating the mounting plate 400 to push the end plate 1000 towards the battery cell later.

[0080] Guide rails are also arranged on the surfaces of the first fixing seat 1100 and the second fixing seat 1200.
