[0046] Reference Figure 1 as well as Figure 2 As shown, the pressing device involved in the embodiment of this application has a first direction x and a second direction y, the first direction x is perpendicular to the second direction y, and the pressing device includes: a base 100, a plurality of first large surface positioning mechanisms 200 and second large surface positioning mechanisms 300.

[0047] Specifically, multiple first large surface positioning mechanisms 200 are disposed on the base 100, and are spaced apart along the first direction x. Each first large surface positioning mechanism 200 includes a first driving member 210 and a first large surface positioning member 220. The first driving member 210 is connected to the first large surface positioning member 220. Two adjacent first large surface positioning members 220 disposed along the first direction x move towards each other along the first direction x, so that the adjacent first large surface positioning members 220 respectively abut against the outer large surface and the top cover 21 of two adjacent batteries 20. A second large surface positioning mechanism 300 is disposed on the base 100 and is located along the first direction x. Between two adjacent first large surface positioning mechanisms 200, the second large surface positioning mechanism 300 includes a second driving member 310, a first station positioning member 321, and a second station positioning member 322. The first station positioning member 321 and the second station positioning member 322 are spaced apart along the first direction x. The second driving member 310 is connected to the first station positioning member 321 and the second station positioning member 322. The first station positioning member 321 and the second station positioning member 322 move in opposite directions along the first direction x so that the first station positioning member 321 and the second station positioning member 322 abut against the inner large surface and the top cover 21 of the two adjacent batteries 20, respectively.

[0048] It should be noted that the first direction x is Figure 1 The direction indicated by x in the middle, and the second direction y is... Figure 1 The direction indicated by y in the middle.

[0049] In the pressing device of this application, since the second large surface positioning mechanism 300 is located between two first large surface positioning mechanisms 200 arranged adjacent to each other along the first direction x, and the first station positioning member 321 and the second station positioning member 322 of the second large surface positioning mechanism 300 are respectively used to abut against the inner large surface and top cover 21 of two adjacent batteries 20, there are two positioning stations between any two adjacent first large surface positioning mechanisms 200. Thus, the housing 22 and top cover 21 of two batteries 20 can be positioned simultaneously between any two adjacent first large surface positioning mechanisms 200. Therefore, the pressing device of this application can simultaneously press the top cover 21 of multiple batteries 20 to improve the pressing efficiency of the top cover 21 and further improve the production efficiency of the batteries 20. During this process, the two first large surface positioning members 220 arranged adjacent to each other along the first direction x move towards each other along the first direction x, so that the adjacent first large surface positioning members 220 abut against the outer large surface and top cover 21 of the two adjacent batteries 20 respectively. In this way, the first large surface positioning members 220 abut against the side of the battery 20 and the top cover 21 away from the second large surface positioning mechanism 300 along the first direction, so that the large surfaces of multiple batteries 20 and top cover 21 are positioned by the first large surface positioning mechanism 200 and the second large surface positioning mechanism 300, so that the top covers 21 of multiple batteries 20 can be pressed in simultaneously.

[0050] Specifically, in this embodiment, both the first station positioning member 321 and the second station positioning member 322 are second large surface positioning members, that is, both the first station positioning member 321 and the second station positioning member 322 abut against the large surface of the battery 20 away from the first large surface positioning member 220.

[0051] Reference Figure 2 as well as Figure 6 As shown, the second large surface positioning mechanism 300 also includes a mounting base 330 and at least two first connecting members 341. The mounting base 330 is fixedly connected to the machine base 100. The at least two first connecting members 341 are spaced apart on the mounting base 330 along the first direction x. The at least two first connecting members 341 are respectively connected to the first station positioning member 321 and the second station positioning member 322. The two first connecting members 341 arranged adjacent to each other along the first direction x move away from each other relative to the mounting base 330 along the first direction x, so as to drive the first station positioning member 321 and the second station positioning member 322 to move away from each other along the first direction x.

[0052] Specifically, in this embodiment, there are two first connectors 341. The two first connectors 341 are spaced apart on the mounting base 330 along the first direction x, and are respectively connected to the first station positioning member 321 and the second station positioning member 322.

[0053] In this embodiment, since the first station positioning member 321 and the second station positioning member 322 are respectively connected to the two first connecting members 341, and the two first connecting members 341 move in opposite directions relative to the mounting base 330 along the first direction x, the two first connecting members 341 can drive the first station positioning member 321 and the second station positioning member 322 to move in opposite directions relative to the mounting base 330 along the first direction x, so that both the first station positioning member 321 and the second station positioning member 322 can extend along the first direction x, thereby enabling the first station positioning member 321 and the second station positioning member 322 to position the inner large surface and the top cover of the two adjacent batteries 20 respectively.

[0054] Reference Figure 6 as well as Figure 7 As shown, the second large surface positioning mechanism 300 also includes at least two second connecting members 342 and two second driving members 310. Each second connecting member 342 is connected to at least one first connecting member 341. The second driving member 310 is connected to the second connecting member 342. At least two second connecting members 342 move relative to the mounting base 330 in opposite directions along the second direction y to drive the two first connecting members 341 to move in opposite directions along the first direction x.

[0055] Specifically, in this embodiment, there are two second connectors 342, each of which is connected to a first connector 341. Each second drive member 310 is connected to a second connector 342. The two second drive members 310 are respectively fixedly connected to the two ends of the mounting base 330 along the second direction y. The first station positioning member 321 and the second station positioning member 322 are both disposed between the two drive members, so as to reduce the size of the pressing device in the first direction x and reduce the equipment space occupied by the pressing device.

[0056] Specifically, in this embodiment, the second driving member 310 is a first driving cylinder. The two first driving cylinders extend or retract synchronously. When the two first driving cylinders extend synchronously, the two first driving members 210 respectively drive the two second connecting members 342 to move towards each other along the second direction y, so that the two second connecting members 342 drive the two first connecting members 341 to move away from each other along the first direction x. This further enables both the first station positioning member 321 and the second station positioning member 322 to extend along the first direction x, so that both the first station positioning member 321 and the second station positioning member 322 can... When the battery 20 and the top cover 21 abut against each other, and the two first drive cylinders retract synchronously, the two first drive members 210 respectively drive the two second connecting members 342 to move in opposite directions along the second direction y, so that the two second connecting members 342 drive the two first connecting members 341 to move in opposite directions along the first direction x, and further enable the first station positioning member 321 and the second station positioning member 322 to retract along the first direction x, so that the first station positioning member 321 and the second station positioning member 322 can disengage from the battery 20 and the top cover 21, so that the pressed battery 20 can enter the next process.

[0057] In this embodiment, two second connecting members 342 can be driven by two second driving members 310 to move relative to the mounting base 330 in opposite directions along the second direction y, so that the two second connecting members 342 can drive the two first connecting members 341 to move in opposite directions along the first direction x, thereby realizing the extension of the first station positioning member 321 and the second station positioning member 322.

[0058] Specifically, in this embodiment, the first connector 341 and the second connector 342 together form a sliding assembly 340, so that the first station positioning member 321 and the second station positioning member 322 can be driven to extend along the first direction x through the sliding assembly 340.

[0059] Continue to refer to Figure 6 as well as Figure 7 As shown, the first connector 341 is provided with a guide hole 3411, and the second connector 342 is provided with a guide part 3421. The guide part 3421 passes through the guide hole 3411. The second connector 342 moves along the second direction y, and drives the first connector 341 to move along the first direction x through the guide part 3421.

[0060] In this embodiment, when the second connector 342 moves along the second direction y, the first connector 341 can be driven to move along the first direction through the cooperation of the guide portion 3421 and the guide hole 3411, so that the first connector 341 can drive the first station positioning member 321 or the second station positioning member 322 to extend along the first direction.

[0061] Reference Figure 6 as well as Figure 8 As shown, the second large surface positioning mechanism 300 also includes a first guide rail 351 and a first guide member 352. The first guide rail 351 is disposed on the mounting base 330. The first connector 341 is connected to the first guide member 352. The first guide rail 351 extends along the first direction x. The first guide member 352 is connected to the first guide rail 351 and slides relative to the first guide rail 351 along the first direction x.

[0062] Specifically, in this embodiment, the guide hole 3411 extends at an angle to the first direction x and the second direction y, that is, the guide hole 3411 is an oblique hole at an angle to the first direction x and the second direction y. When the second driving member 310 drives the second connecting member 342 to move along the second direction y, part of the structure of the second connecting member 342 passing through the guide hole 3411 will abut against the hole wall of the guide hole 3411. Therefore, the second connecting member 342 can push the first connecting member 341 by abutting against the hole wall of the guide hole 3411. Since the first guide member 352 is connected to the first connector 341, the first guide rail 351 extends along the first direction x, and the first guide member slides relative to the first guide rail 351 along the first direction x, when the second connector 342 pushes the first connector 341, the first guide member 352 can guide the movement of the first connector 341 through the cooperation of the first guide member 352 and the first guide rail 351, so that the first connector 341 can move along the first direction x, so as to realize the extension of the first station positioning member 321 or the second station positioning member 322 in the first direction x.

[0063] In this embodiment, the first guide rail 351 can guide the movement of the first guide member 352, so that the first guide member 352 can slide along the first direction x. Since each first connector 341 is connected to the first guide member 352, and the mounting base 330 is provided with the first guide rail 351 at both ends along the second direction y, the two first guide members 352 can guide the two first connectors 341 respectively, so that the two first connectors 341 can move along the first direction x, thereby allowing the first station positioning member 321 and the second station positioning member 322 to extend along the first direction x.

[0064] Continue to refer to Figure 6 as well as Figure 8 As shown, the second large surface positioning mechanism 300 also includes a second guide rail 361 and a second guide member 362. The mounting base 330 is provided with a second guide rail 361 at both ends along the first direction x, and the second guide rail 361 extends along the second direction y. Each second connector 342 is connected to a second guide member 362, and each second guide member 362 is connected to a second guide rail 361 and slides relative to the second guide rail 361 along the second direction y.

[0065] In this embodiment, since the second guide rail 361 extends along the second direction y and the second guide member 362 slides relative to the second guide rail 361 along the second direction y, the second guide rail 361 can guide the second guide member 362, allowing the second guide member 362 to move along the second direction y. Since each second connector 342 is connected to a second guide member 362, the two second guide members 362 can guide the two second connectors 342 respectively, allowing both second connectors 342 to move along the second direction y, thereby enabling the two second connectors 342 to drive the two first connectors 341 respectively.

[0066] Reference Figure 1 as well as Figure 10 As shown, the pressing device also has a third direction z, which is perpendicular to the first direction x and the second direction y respectively. The base 100 is provided with a plurality of feeding channels 110 that pass through the base 100 along the third direction z. The plurality of feeding channels 110 are spaced apart along the first direction x. The feeding channels 110 are all used for feeding the battery 20. The first large surface positioning mechanism 200 and the second large surface positioning mechanism 300, which are arranged adjacent to each other along the first direction x, are located on both sides of the feeding channel 110 along the first direction x respectively.

[0067] It should be noted that the third party is z. Figure 1 The direction indicated by z in the middle.

[0068] In this embodiment, since the feeding channel 110 penetrates the base 100 along the third direction z, and the first large surface positioning mechanism 200 and the second large surface positioning mechanism 300, which are arranged adjacent to each other along the first direction x, are respectively located on both sides of the feeding channel 110 along the first direction x, when the battery 20 is inserted into the feeding channel 110, it can not only achieve the positioning of the large surfaces on both sides of the battery 20, but also avoid the machine base 100 from interfering with the positioning and pressing of the battery 20. Since the machine base 100 has multiple feeding channels 110 arranged at intervals along the first direction x, it can achieve feeding avoidance of multiple batteries 20 through multiple feeding channels 110, so as to facilitate the simultaneous pressing of the top cover 21 of multiple batteries 20.

[0069] Reference Figure 1 as well as Figure 9As shown, the pressing device of this application also includes a plurality of small face positioning mechanisms 400. The plurality of small face positioning mechanisms 400 are arranged at intervals along the first direction x. Each small face positioning mechanism 400 includes a first small face positioning member 420 and a second small face positioning member 430. The first small face positioning member 420 and the second small face positioning member 430 are respectively located on both sides of the feeding channel 110 along the second direction y. The first small face positioning member 420 and the second small face positioning member 430 move towards each other and extend along the second direction y so that the first small face positioning member 420 and the second small face positioning member 430 abut against the battery 20.

[0070] Specifically, in this embodiment, the facet positioning mechanism 400 further includes a third driving member 410, which is connected to the first facet positioning member 420 and the second facet positioning member 430, and drives the first facet positioning member 420 and the second facet positioning member 430 to move towards each other along the second direction y, so that the first facet positioning member 420 abuts against one side facet and top cover 21 of the battery 20, and the second facet positioning member 430 abuts against the other side facet and top cover 21 of the battery 20.

[0071] Specifically, in this embodiment, the third driving member 410 is also used to drive the first small face positioning member 420 and the second small face positioning member 430 to move back in opposite directions along the second direction y, so that the first small face positioning member 420 is disengaged from one side of the small face and the top cover 21 of the battery 20, and the second small face positioning member 430 is disengaged from the other side of the small face and the top cover 21 of the battery 20, so that the pressed battery 20 can enter the next process.

[0072] In this embodiment, the small face positioning mechanism 400 is used to abut against the small face and top cover 21 of the battery 20 to position the small face and top cover 21 of the battery 20. During this process, since the third driving member 410 can drive the first small face positioning member 420 and the second small face positioning member 430 to move and extend in opposite directions along the second direction y, the first small face positioning member 420 can abut against one side of the small face and top cover 21 of the battery 20, and the second small face positioning member 430 can abut against the other side of the small face and top cover 21 of the battery 20. Thus, the positioning of the small face and top cover 21 of the battery 20 is achieved by the first small face positioning member 420 and the second small face positioning member 430. At the same time, since the pressing device includes multiple small face positioning mechanisms 400, and each small face positioning mechanism 400 is provided at a feeding groove 110, multiple small face positioning mechanisms 400 can be used to position multiple batteries 20 respectively, so as to facilitate the simultaneous pressing of the top covers 21 of multiple batteries 20.

[0073] Specifically, continue to refer to Figure 9As shown, in this embodiment, the facet positioning mechanism 400 further includes a third guide rail 460 and a third guide member 470 slidably connected to the third guide rail 460. The third guide rail 460 is fixedly connected to the base 100 and extends along the second direction y. The first facet positioning member 420 and the second facet positioning member 430 are both provided with the third guide rail 460 on both sides along the first direction x, and the first facet positioning member 420 and the second facet positioning member 430 are both connected with the third guide member 470 on both sides along the first direction x. When the third driving member 410 drives the facet positioning assembly to move along the second direction y, each third guide member 470 slides relative to a third guide rail 460 along the second direction y. In this way, the cooperation between the third guide rail 460 and the third guide member 470 can guide the movement of the first facet positioning member 420 and the second facet positioning member 430, ensuring that the first facet positioning member 420 and the second facet positioning member 430 can move along the second direction y.

[0074] Specifically, continue to refer to Figure 9 As shown, in this embodiment, the facet positioning mechanism 400 further includes two mounting members 480. Both mounting members 480 are fixedly connected to the base 100 and are spaced apart along the second direction y. The first facet positioning member 420 is slidably connected to one of the mounting members 480, and the second facet positioning member 430 is slidably connected to the other mounting member 480. Both the first facet positioning member 420 and the second facet positioning member 430 slide relative to the mounting member 480 along the second direction y, so that the first facet positioning member 420 and the second facet positioning member 430 are connected to the base 100 through the mounting member 480, thereby improving the structural stability and motion stability of the first facet positioning member 420 and the second facet positioning member 430.

[0075] Reference Figure 3 As shown, the first large surface positioning mechanism 200 also includes a fixed base 230 and a third connecting member 240 connected to the fixed base 230. The fixed base 230 is fixedly connected to the base 100. The first large surface positioning member 220 is connected to the third connecting member 240. The first driving member 210 is fixedly connected to the fixed base 230 and connected to the third connecting member 240. The first driving member 210 is used to drive the third connecting member 240 to move relative to the fixed base 230 along the first direction x, so as to drive the first large surface positioning member 220 to move along the first direction x. The third connecting member 240 is provided with a first expansion member 260.

[0076] In this embodiment, the first driving member 210 can be fixed to the base 100 by the fixing seat 230, and the third connecting member 240 is connected to the base 100. Since the first driving member 210 is used to drive the third connecting member 240 to move relative to the fixing seat 230 along the first direction x, and the first large surface positioning member 220 is connected to the third connecting member 240, the first driving member 210 can drive the third connecting member 240 to move relative to the fixing seat 230 along the first direction x, so that the first large surface positioning member 220 can move relative to the fixing seat 230 along the first direction x, thereby realizing the extension of the first large surface positioning member 220 along the first direction x, and further enabling the first large surface positioning member 220 to abut against one side of the large surface of the battery 20 and the top cover 21.

[0077] Continue to refer to Figure 3 As shown, the first large surface positioning mechanism 200 also includes a fifth driving member 250 and a first expanding shell member 260. The fifth driving member 250 is disposed on the third connecting member 240 and connected to the first expanding shell member 260. The first expanding shell member 260 is slidably connected to the third connecting member 240. The fifth driving member 250 is used to drive the first expanding shell member 260 to slide relative to the third connecting member 240 along the first direction x, so that the first expanding shell member 260 is adsorbed and connected to the large surface of the battery 20 near the first large surface positioning member 220.

[0078] In this embodiment, the fifth driving member 250 can be connected to the base 100 via the third connecting member 240 to improve the structural stability of the fifth driving member 250. Simultaneously, the third connecting member 240 facilitates the installation of the fifth driving member 250 and the first expanding shell member 260. The fifth driving member 250 and the first expanding shell member 260 can be installed on the third connecting member 240 first, and then the entire first large-surface positioning mechanism 200 can be installed on the base 100, thus improving the assembly convenience of the press-fitting device of this application. Furthermore, since the first expanding shell member 260 is slidably connected to the third connecting member 240, and the fifth driving member 250 is used to drive the first expanding shell member 260 relative to the third connecting member... 240 slides along the first direction x, so that the first expansion member 260 can be driven by the fifth driving member 250 to slide relative to the third connecting member 240 along the first direction x, so that the first expansion member 260 extends along the first direction x, and further allows the first expansion member 260 to be adsorbed and connected to the large surface of the battery housing 22 near the first large surface positioning member 220. In this way, the first expansion member 260 can expand the large surface of the battery 20 near the first large surface positioning member 220. When the top cover 21 is pressed into the battery 20, the risk of interference between the edge of the large surface of the battery 20 near the first large surface positioning member 220 and the top cover 21 can be reduced, and the risk of damage to the battery 20 during the pressing process can be reduced.

[0079] Specifically, refer to Figure 5 As shown, the second large-area positioning mechanism 300 also includes a sixth driving member 370 and a second expanding member 380. The sixth driving member 370 is disposed on the first connecting member 341 and is a driving cylinder. The second expanding member 380 is connected to the piston rod of the driving cylinder. The driving cylinder is used to drive the second expanding member 380 to move relative to the first connecting member 341 along the first direction x, so that the second expanding member 380 is adsorbed and connected to the large surface of the battery 20 near the second large-area positioning member. In this way, the second expanding member 380 can be driven by the sixth driving member 370. The second expansion member 380 slides relative to the first connector 341 along the first direction x, so that the second expansion member 380 extends along the first direction x, and further enables the second expansion member 380 to be adsorbed and connected to the large surface of the battery housing 22 near the second large surface positioning member. In this way, the large surface of the battery 20 near the second large surface positioning member can be expanded by the second expansion member 380. When the top cover 21 is pressed into the battery 20, the risk of interference between the edge of the large surface of the battery 20 near the second large surface positioning member and the top cover 21 can be reduced, and the risk of damage to the battery 20 during the pressing process can be reduced.

[0080] Reference Figure 4 As shown, the first large-area positioning member 220 has a first positioning part 221 and a second positioning part 222. The first positioning part 221 is used to abut against the top cover 21, and the second positioning part 222 is used to abut against the battery 20. The first positioning part 221 and the second positioning part 222 are spaced apart along the third direction z. An avoidance groove 223 is provided on the second positioning part 222. The avoidance groove 223 is recessed in the direction away from the first positioning part 221 along the third direction z, so that the top of the battery 20 is located within the range of the avoidance groove 223.

[0081] In this embodiment, when the first large-surface positioning member 220 abuts against one side of the large-surface of the battery 20 and the top cover 21, the first positioning part 221 abuts against the top cover 21, and the second positioning part 222 abuts against one side of the large-surface of the battery 20. This allows the battery 20 and the top cover 21 to be positioned respectively by the first positioning part 221 and the second positioning part 222. Furthermore, since the first positioning part 221 and the second positioning part 222 are spaced apart along a third direction z, and the second positioning part 222 has an avoidance groove 223, Therefore, the top of the battery 20 can be located within the range of the clearance groove 223 in the third direction z. Thus, the clearance groove 223 can reserve deformation space for the top of the battery 20. When the top cover 21 is pressed into the battery 20, the top of the battery 20 will deform outward due to the compression of the top cover 21. The clearance groove 223 can prevent the first positioning part 221 of the first large surface positioning member 220 from interfering with the deformed top of the battery 20, and prevent the first large surface positioning member 220 from damaging the battery 20.

[0082] Specifically, refer to Figure 4 As shown, in this embodiment, in the first direction x, the first positioning part 221 is positioned closer to the battery than the second positioning part 222. In order for the top cover 21 to be successfully pressed into the battery 20, the size of the top cover 21 is smaller than the size of the battery 20 when it is manufactured. When the first positioning part 221 is positioned closer to the battery than the second positioning part 222, the first positioning part 221 can abut against the smaller top cover 21, while the second positioning part 222 abuts against the larger battery 20. This achieves the positioning of the battery 20 and the top cover 21 by the first positioning part 221 and the second positioning part 222, respectively.

[0083] Specifically, refer to Figure 5 as well as Figure 9 As shown, in this embodiment, the second large surface positioning member, the first small surface positioning member 420, and the second small surface positioning member 430 all have a first positioning part 221 and a second positioning part 222, so that the second large surface positioning member, the first small surface positioning member 420, and the second small surface positioning member 430 can accurately position the battery 20 and the top cover 21, so that the central axis of the top cover 21 can coincide with the central axis of the top of the battery 20, thereby facilitating the pressing of the top cover 21 and reducing the possibility of interference between the top cover 21 and the top edge of the battery 20 during the pressing process.

[0084] Reference Figure 1 as well as Figure 11 As shown, the pressing device also includes a clamping mechanism 500, which is used to clamp the battery 20 during the pressing of the top cover 21 to prevent the battery 20 from shifting along the third direction z during the pressing process.

[0085] Reference Figure 9 As shown, the small face positioning mechanism 400 also includes a plurality of first limiting members 450. The plurality of first limiting members 450 are respectively located on both sides of the feeding channel 110 along the second direction y, and the first limiting members 450 and the first small face positioning member 420 are spaced apart along the third direction z. At least two first limiting members 450 move towards each other and extend along the second direction y so that at least two first limiting members 450 abut against the battery.

[0086] Specifically, in this embodiment, the facet positioning mechanism 400 further includes a fourth driving member 440, and the number of first limiting members 450 is two. The first facet positioning member 420 and one first limiting member 450 are spaced apart along the third direction z, and the second facet positioning member 430 and another first limiting member 450 are spaced apart along the third direction z. The fourth driving member 440 is disposed on the base 100 and connected to the two first limiting members 450. The fourth driving member 440 is used to drive the two first limiting members 450 to move towards each other and extend along the second direction y, so that the two first limiting members 450 respectively abut against the two facets of the battery 20 along the second direction y.

[0087] In this embodiment, after the top cover 21 is pressed, the two first limiting members 450 can be driven by the fourth driving member 440 to move and extend in opposite directions along the second direction y, so that the two first limiting members 450 respectively abut against the small surfaces on both sides of the battery 20 along the second direction y. At the same time, with the adsorption effect of the first expanding shell member 260 and the second expanding shell member 380 on the large surface of the battery 20 along the first direction x, the two first limiting members 450, the first expanding shell member 260 and the second expanding shell member 380 can simultaneously abut against the battery 20, so that the clamping mechanism 500 can disengage from the battery 20, and the clamping mechanism 500 can clamp the next battery 20 to be pressed, thereby improving the pressing efficiency of the pressing device of this application.

[0088] Specifically, in this embodiment, referring to Figure 9 As shown, each of the two first limiting members 450 has at least a partially uneven anti-slip layer 451 on the side near the battery 20, so as to increase the friction between the first limiting member 450 and the battery 20 through the anti-slip layer 451, thereby improving the stability of the first limiting member 450 abutting against the battery 20.

[0089] Reference Figure 11As shown, the clamping mechanism 500 includes a clamping seat 510, a first clamping assembly 520, and a second clamping assembly 530. The clamping seat 510 is disposed on the base 100, and the first clamping assembly 520 and the second clamping assembly 530 are respectively disposed on both sides of the clamping seat 510 along the first direction x. Before pressing the top cover 21, the battery 20 to be pressed is placed between the first clamping assembly 520 and the second clamping assembly 530. The clamping seat 510 is used to abut against the side of the housing 22 away from the top cover 21 along the third direction z. A first clamping assembly 520 and a second clamping assembly 530 are respectively used to abut against both sides of the housing 22 along the first direction x and the side of the housing 22 near the top cover 21 along the third direction z, so as to clamp the battery 20 by means of the first clamping assembly 520 and the second clamping assembly 530, so as to facilitate the subsequent pressing of the top cover 21. At the same time, since the first clamping assembly 520 and the second clamping assembly 530 are respectively used to abut against the side of the housing 22 near the top cover 21 along the third direction z, the battery 20 can be clamped by means of the first clamping assembly 520 and the second clamping assembly 530. The two clamping components 530 isolate the unpressed top cover 21 from the housing 22, so that the first clamping component 520 and the second clamping component 530 are located between the top cover 21 and the housing 22, preventing the top cover 21 from falling into the housing 22. This facilitates the positioning of the housing 22 and the top cover 21 by the first large surface positioning mechanism 200, the second large surface positioning mechanism 300, and the small surface positioning mechanism 400. During the pressing of the top cover 21, the first clamping component 520 and the second clamping component 530 are spaced apart from the housing 22 to prevent... The first clamping assembly 520 and the second clamping assembly 530 interfere with the pressing of the top cover 21. After the top cover 21 is pressed, the first clamping assembly 520 and the second clamping assembly 530 are used to abut against the two sides of the housing 22 along the first direction x and the side of the top cover 21 away from the housing 22 along the third direction z, so as to apply pressure to the top cover 21 along the third direction z towards the housing 22 through the first clamping assembly 520 and the second clamping assembly 530, thereby improving the stability of the connection structure between the top cover 21 and the housing 22 after pressing.

Both the first clamping member 521 and the second clamping member 531 are slidably connected to the clamping seat 510. Both the first clamping member 521 and the second clamping member 531 are connected to the seventh driving member 540. The seventh driving member 540 is used to drive the first clamping member 521 and the second clamping member 531 to move towards or away from the clamping seat 510 along the first direction x. When the seventh driving member 540... When the first clamping member 521 and the second clamping member 531 move towards each other relative to the clamping seat 510 along the first direction x, the first clamping member 521 abuts against one side of the battery 20 along the first direction x, and the second clamping member 531 abuts against the side of the battery 20 away from the second clamping member 531 along the first direction x. When the seventh driving member 540 drives the first clamping member 521 and the second clamping member 531 to move away from each other relative to the clamping seat 510 along the first direction x, the first clamping member 521 disengages from one side of the battery 20 along the first direction x, and the second clamping member 531 disengages from the side of the battery 20 away from the second clamping member 531 along the first direction x.

This allows the first large surface positioning mechanism 200, the second large surface positioning mechanism 300 and the small surface positioning mechanism 400 to make fine adjustments in the third direction z when positioning the battery 20 and the top cover 21, and further enables the first large surface positioning mechanism 200, the second large surface positioning mechanism 300 and the small surface positioning mechanism 400 to accurately position the battery 20 and the top cover 21.

[0094] Continue to refer to Figure 12 As shown, the clamping base 510 includes a connecting portion 511 and a clamping portion 512 connected to the connecting portion 511.

The tenth driving member 550 is disposed on the connecting portion 511 and connected to the clamping portion 512. The tenth driving member 550 is used to drive the clamping portion 512 to move relative to the connecting portion 511 along the third direction z, so that the battery 20 clamped by the first clamping component 520 and the second clamping component 530 moves in the third direction z.

[0095] Reference Figure 1 as well as Figure 13As shown, the pressing device also includes a pressing mechanism 600, which is disposed on the base 100. The clamping mechanism 500 and the pressing mechanism 600 are respectively located on both sides of the base 100 along the third direction z. The pressing mechanism 600 is used to abut against the end of the top cover 21 away from the battery 20 along the third direction z, and to press the top cover 21 into the battery 20 along the third direction z.

[0096] Reference Figure 13 As shown, the pressing mechanism 600 includes a pressing frame 610, an eleventh drive member 620, and a pressing assembly 630. The pressing assembly 630 is located on the side of the feeding channel 110 away from the clamping mechanism 500 along the third direction z.

[0098] Continue to refer to Figure 14As shown, the third pressing part 6313 located at one end of the first pressing part 6311 along the first direction x is spaced apart from the third pressing part 6313 located at the other end of the first pressing part 6311 along the first direction x, so as to define the first clearance space 6314. The pressing part 631 also has a liquid injection hole protection part 6315, which is connected to the first pressing part 6311 and located in the first clearance space 6314. When the pressing part 631 presses the top cover 21, the liquid injection hole protection part 6315 covers the liquid injection hole to protect the liquid injection hole and prevent metal debris generated during the pressing process from entering the battery through the liquid injection hole, thus avoiding damage to the battery interior.

Each dust removal hole 632 is externally connected to a vacuum dust removal device. During the pressing process of the top cover 21, the metal debris generated can enter the dust removal groove 6317 through the first clearance space 6314 and the second clearance space 6316, and be removed by the vacuum dust removal device in the dust removal hole 632, so as to remove the metal debris generated during the pressing process and reduce the damage of metal debris to the battery.

[0100] Continue to refer to Figure 14 As shown, each third pressing part 6313 is provided with an adsorption groove 6318, and each adsorption groove 6318 is connected to at least one dust removal hole 632, so that the third pressing part 6313 can adsorb the edges of both ends of the top cover 21 along the first direction x, that is, can adsorb the middle part of the long side of the top cover 21, so as to offset the partial squeezing force of the pressing part 631 on the long side of the top cover 21 and prevent the top cover 21 from being crushed by the pressing part 631 during the pressing process.

[0101] Reference Figure 13As shown, the pressing mechanism 600 also includes a second limiting member 640 and a guide member 650. The second limiting member 640 and the pressing assembly 630 are respectively located on both sides of the pressing frame 610 along the third direction z. The second limiting member 640 is disposed on the pressing frame 610 and protrudes from the pressing frame 610 along the third direction z in a direction away from the pressing assembly 630. A guide hole is provided on the pressing frame 610, and the guide member 650 passes through the guide hole. In the third direction z, one end of the guide member 650 is connected to the pressing assembly 630, and the other end of the guide member 650 is spaced apart from the end of the second limiting member 640 away from the pressing frame 610 along the third direction z. When the eleventh driving member 620 drives the pressing assembly 630 along the third direction z... When the guide 650 moves closer to the top cover 21, it slides within the guide hole relative to the pressing frame 610 until the guide 650 abuts against the end of the second limiting member 640 away from the pressing frame 610. After the guide 650 abuts against the second limiting member 640, the second limiting member 640 can stop the guide 650 from moving along the third direction z, so that the eleventh driving member 620 stops driving the pressing assembly 630. In this way, the second limiting member 640 can limit the distance the pressing assembly 630 moves along the third direction z, avoiding damage to the battery caused by excessive movement of the pressing assembly 630 along the third direction z, and at the same time avoiding damage to other structures of the pressing device and the safety of the operators caused by the pressing assembly 630.

[0102] Reference Figure 13 As shown, the pressing mechanism 600 includes a plurality of eleventh driving members 620 and pressing components 630. The plurality of pressing components 630 are spaced apart along a first direction x, and each pressing component 630 is provided corresponding to a feeding channel 110. Each eleventh driving member 620 is used to connect with a pressing component 630 and to drive the pressing component 630 connected thereto to move along a third direction z, so that each pressing component 630 can press a top cover 21. Thus, the pressing device of this application can press the top covers 21 of multiple batteries simultaneously.

[0103] Specifically, in this embodiment, the clamping mechanism 500 further includes an eleventh driving member, which is connected to the clamping seat 510 and is used to drive the clamping seat 510 to move along the first direction x, the second direction y and the third direction z, so that the clamping seat 510 drives the battery 20 to pass through the feeding channel 110, so that the first large surface positioning mechanism 200, the second large surface positioning mechanism 300 and the small surface positioning mechanism 400 can position the top cover 21 and the housing 22 of the battery 20, and at the same time facilitate the pressing mechanism 600 to press the top cover 21.
