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

[0047] Specifically, a plurality of first large surface positioning mechanisms 200 are arranged on the base 100, and the plurality of first large surface positioning mechanisms 200 are arranged at intervals along the first direction x. The 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 first large surface positioning members 220 arranged adjacent to each other along the first direction x move toward each other along the first direction x, so that the adjacent first large surface positioning members 220 are respectively in contact with the outer large surfaces of the two adjacent batteries 20 and the top cover 21; the second large surface positioning mechanism 300 is arranged on the base 100 and is located along the first direction x. Between the 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 oppositely along the first direction x, so as to make the first station positioning member 321 and the second station positioning member 322 respectively abut against the inner large surfaces and the top cover 21 of the two adjacent batteries 20.

[0048] It should be noted that the first direction x is Figure 1 The direction pointed by x is Figure 1 The direction that y points to.

[0049] In the pressing device of the present application, since the second large surface positioning mechanism 300 is located between two first large surface positioning mechanisms 200 adjacently arranged 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 surfaces and the top cover 21 of the two adjacent batteries 20, therefore, there are two positioning stations between any two adjacent first large surface positioning mechanisms 200, and the shell 22 and the top cover 21 of the two batteries 20 can be positioned simultaneously between any two adjacent first large surface positioning mechanisms 200. Therefore, the pressing device of the present application can simultaneously press-fit the top covers 21 of multiple batteries 20 to improve the pressing efficiency of the top covers 21, and further improve the production efficiency of the batteries 20. In this process, the two first large surface positioning members 220 adjacently arranged along the first direction x move toward each other along the first direction x, so that the adjacent first large surface positioning members 220 are respectively abutted against the outer large surfaces and top covers 21 of the two adjacent batteries 20. In this way, the first large surface positioning member 220 can abut against a surface of the battery 20 and the top cover 21 away from the second large surface positioning mechanism 300 along the first direction, so as to position the large surfaces of multiple batteries 20 and top covers 21 through the first large surface positioning mechanism 200 and the second large surface positioning mechanism 300, so as to facilitate the subsequent simultaneous press-fitting of the top covers 21 of multiple batteries 20.

[0050] Specifically, in this embodiment, the first station positioning member 321 and the second station positioning member 322 are both second large surface positioning members, that is, the first station positioning member 321 and the second station positioning member 322 are both in contact with 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 seat 330 and at least two first connecting members 341. The mounting seat 330 is fixedly connected to the machine base 100. At least two first connecting members 341 are arranged on the mounting seat 330 at intervals along the first direction x. At least two first connecting members 341 are respectively connected one by one with the first station positioning member 321 and the second station positioning member 322. The two first connecting members 341 adjacently arranged along the first direction x move opposite to each other relative to the mounting seat 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 opposite to each other along the first direction x.

[0052] Specifically, in this embodiment, the number of the first connecting members 341 is two, and the two first connecting members 341 are arranged on the mounting seat 330 at intervals along the first direction x, and are respectively connected to the first station positioning member 321 and the second station positioning member 322 one by one.

[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 opposite to each other along the first direction x relative to the mounting seat 330, the first station positioning member 321 and the second station positioning member 322 can be driven by the two first connecting members 341 to move opposite to each other along the first direction x relative to the mounting seat 330, so that the first station positioning member 321 and the second station positioning member 322 can both extend along the first direction x, thereby allowing the first station positioning member 321 and the second station positioning member 322 to respectively position the inner large surfaces and the top covers of the two adjacent batteries 20.

[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, the number of second driving members 310 is two, 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, and at least two second connecting members 342 move toward each other along the second direction y relative to the mounting seat 330 to drive the two first connecting members 341 to move away from each other along the first direction x.

[0055] Specifically, in this embodiment, the number of second connecting members 342 is two, each second connecting member 342 is connected to a first connecting member 341, each second driving member 310 is connected to a second connecting member 342, and the two second driving members 310 are respectively fixedly connected to the two ends of the mounting base 330 along the second direction y, and the first workstation positioning member 321 and the second workstation positioning member 322 are both arranged between the two driving members to reduce the size of the pressing device of the present application 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, and 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 toward each other 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 extend along the first direction x, so that the first station positioning member 321 and the second station positioning member 322 can both be aligned with the first station positioning member 321. The battery 20 and the top cover 21 are against each other. When the two first driving cylinders shrink synchronously, the two first driving members 210 respectively drive the two second connecting members 342 to move away from each other along the second direction y, so that the two second connecting members 342 drive the two first connecting members 341 to move toward each other along the first direction x, and further enable the first station positioning member 321 and the second station positioning member 322 to be retracted along the first direction x, so that the first station positioning member 321 and the second station positioning member 322 can be detached from the battery 20 and the top cover 21, so that the pressed battery 20 can enter the next process.

[0057] In this embodiment, the two second driving members 310 can drive the two second connecting members 342 to move toward each other along the second direction y relative to the mounting seat 330, so that the two second connecting members 342 can drive the two first connecting members 341 to move away from each other along the first direction x, thereby realizing the extension of the first workstation positioning member 321 and the second workstation positioning member 322.

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

[0059] Continue to refer to Figure 6 as well as Figure 7 As shown, the first connecting member 341 is provided with a guide hole 3411, and the second connecting member 342 is provided with a guide portion 3421. The guide portion 3421 is inserted into the guide hole 3411. The second connecting member 342 moves along the second direction y, and the first connecting member 341 is driven to move along the first direction x through the guide portion 3421.

[0060] In this embodiment, when the second connecting member 342 moves along the second direction y, it can drive the first connecting member 341 to move along the first direction through the cooperation between the guide portion 3421 and the guide hole 3411, so that the first connecting member 341 can drive the first workstation positioning member 321 or the second workstation 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 arranged on the mounting seat 330. The first connecting member 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 along the first direction x relative to the first guide rail 351.

[0062] Specifically, in the present embodiment, the guide hole 3411 is extended in a direction that is angled with the first direction x and the second direction y, that is, the guide hole 3411 is an inclined hole that is angled with 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, a portion of the second connecting member 342 that is inserted into 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 connecting member 341 is connected to the first guide member 352, the first guide rail 351 is extended along the first direction x, and the first guide member slides along the first direction x relative to the first guide rail 351. Therefore, when the second connecting member 342 pushes the first connecting member 341, the movement of the first connecting member 341 can be guided by the cooperation between the first guide member 352 and the first guide rail 351, so that the first connecting member 341 can move along the first direction x 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 connecting member 341 is connected to a first guide member 352, and the mounting seat 330 is provided with first guide rails 351 at both ends along the second direction y, the two first guide members 352 can respectively guide the two first connecting members 341 so that the two first connecting members 341 can both move along the first direction x, thereby allowing the first workstation positioning member 321 and the second workstation positioning member 322 to both 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 second guide rails 361 are provided at both ends of the mounting seat 330 along the first direction x, and the second guide rails 361 are extended along the second direction y. Each second connecting member 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 along the second direction y relative to the second guide rail 361, the second guide rail 361 can guide the second guide member 362 so that the second guide member 362 can move along the second direction y. Since each second connecting member 342 is connected to a second guide member 362, the two second guide members 362 can guide the two second connecting members 342 respectively so that the two second connecting members 342 can move along the second direction y, thereby realizing the driving of the two first connecting members 341 by the two second connecting members 342 respectively.

[0066] Reference Figure 1 as well as Fig.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. The base 100 is provided with a plurality of feeding grooves 110 that penetrate the base 100 along the third direction z. The plurality of feeding grooves 110 are arranged at intervals along the first direction x. The feeding grooves 110 are all used for feeding the batteries 20. The first large surface positioning mechanism 200 and the second large surface positioning mechanism 300 that are adjacently arranged along the first direction x are respectively located on both sides of the feeding groove 110 along the first direction x.

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

[0068] In this embodiment, since the feeding slot 110 passes through the base 100 along the third direction z, and the first large surface positioning mechanism 200 and the second large surface positioning mechanism 300 adjacently arranged along the first direction x are respectively located on both sides of the feeding slot 110 along the first direction x, when the battery 20 is inserted into the feeding slot 110, it is possible to achieve positioning of the large surfaces on both sides of the battery 20, and avoid interference of the base 100 with the positioning and press-fitting of the battery 20. Furthermore, since the base 100 is provided with a plurality of feeding slots 110 spaced apart along the first direction x, the plurality of feeding slots 110 can be used to avoid feeding of a plurality of batteries 20, thereby facilitating the subsequent simultaneous press-fitting of the top covers 21 of the plurality of batteries 20.

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

[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 and forth along the second direction y, so that the first small face positioning member 420 is disengaged from the small face on one side of the battery 20 and the top cover 21, and the second small face positioning member 430 is disengaged from the small face on the other side of the battery 20 and the top cover 21, 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 the small face of the battery 20 and the top cover 21 to position the small face and the top cover 21 of the battery 20. In 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 toward each other and extend along the second direction y, the first small face positioning member 420 can abut against the small face and the top cover 21 on one side of the battery 20, and the second small face positioning member 430 can abut against the small face and the top cover 21 on the other side of the battery 20, thereby realizing the positioning of the small face and the top cover 21 of the battery 20 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 a plurality of small face positioning mechanisms 400, and each small face positioning mechanism 400 is arranged at a feeding slot 110, the plurality of batteries 20 can be positioned respectively by the plurality of small face positioning mechanisms 400, so as to facilitate the subsequent simultaneous pressing of the top covers 21 of the plurality of batteries 20.

[0073] Specifically, continue to refer to Fig. 9As shown, in the present embodiment, the small face positioning mechanism 400 also includes a third guide rail 460 and a third guide member 470 slidably connected to the third guide rail 460.

When the third driving member 410 drives the small face positioning assembly to move along the second direction y, each third guide member 470 slides along the second direction y relative to a third guide rail 460. In this way, the cooperation between the third guide rail 460 and the third guide member 470 can guide the movement of the first small face positioning member 420 and the second small face positioning member 430, thereby ensuring that the first small face positioning member 420 and the second small face positioning member 430 can move along the second direction y.

[0074] Specifically, continue to refer to Fig. 9 As shown, in the present embodiment, the small face positioning mechanism 400 also includes two mounting members 480, both of which are fixedly connected to the base 100 and spaced apart along the second direction y, the first small face positioning member 420 is slidably connected to one of the mounting members 480, the second small face positioning member 430 is slidably connected to the other mounting member 480, and the first small face positioning member 420 and the second small face positioning member 430 both slide relative to the mounting member 480 along the second direction y, so as to connect the first small face positioning member 420 and the second small face positioning member 430 to the base 100 through the mounting member 480, thereby improving the structural stability and movement stability of the first small face positioning member 420 and the second small face positioning member 430.

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

[0076] In this embodiment, the first driving member 210 can be fixed to the base 100 through the fixing base 230, and at the same time, 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 along the first direction x relative to the fixing base 230, and the first large surface positioning member 220 is connected to the third connecting member 240, the third connecting member 240 can be driven by the first driving member 210 to move along the first direction x relative to the fixing base 230, so that the first large surface positioning member 220 can move along the first direction x relative to the fixing base 230, 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 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 shell expansion member 260. The fifth driving member 250 is arranged on the third connecting member 240 and connected to the first shell expansion member 260. The first shell expansion member 260 is slidably connected to the third connecting member 240. The fifth driving member 250 is used to drive the first shell expansion member 260 to slide relative to the third connecting member 240 along the first direction x, so that the first shell expansion member 260 is adsorbed and connected to the large surface of the battery 20 close to the first large surface positioning member 220.

[0078] In this embodiment, the fifth driving member 250 can be connected to the base 100 through the third connecting member 240 to improve the structural stability of the fifth driving member 250. At the same time, the third connecting member 240 can facilitate the installation of the fifth driving member 250 and the first expansion shell member 260. The fifth driving member 250 and the first expansion 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 to improve the assembly convenience of the press-fitting device of the present application. Furthermore, since the first expansion shell member 260 is slidably connected to the third connecting member 240, and the fifth driving member 250 is used to drive the first expansion shell member 260 relative to the third connecting member 240 slides along the first direction x, so that the first shell expansion member 260 can be driven by the fifth driving member 250 to slide along the first direction x relative to the third connecting member 240, so that the first shell expansion member 260 can extend along the first direction x, and further enable the first shell expansion member 260 to be adsorbed and connected with the large surface of the battery shell 22 close to the first large surface positioning member 220. In this way, the large surface of the battery 20 close to the first large surface positioning member 220 can be expanded by the first shell expansion member 260. When the top cover 21 is pressed into the battery 20, the risk of interference between the large surface edge of the battery 20 close to the first large surface positioning member 220 and the top cover 21 can be reduced, thereby reducing the risk of damaging the battery 20 during the pressing process.

[0079] Specifically, refer to Figure 5 As shown, the second large surface positioning mechanism 300 also includes a sixth driving member 370 and a second shell expansion member 380. The sixth driving member 370 is arranged on the first connecting member 341. The sixth driving member 370 is a driving cylinder. The second shell expansion member 380 is connected to the piston rod of the driving cylinder. The driving cylinder is used to drive the second shell expansion member 380 to move relative to the first connecting member 341 along the first direction x, so that the second shell expansion member 380 is adsorbed and connected with the large surface of the battery 20 close to the second large surface positioning member. In this way, the second shell expansion member 380 can be driven by the sixth driving member 370. 0 slides along the first direction x relative to the first connecting member 341, so that the second shell expansion member 380 extends along the first direction x, and further enables the second shell expansion member 380 to be adsorbed and connected with the large surface of the battery shell 22 close to the second large surface positioning member. In this way, the large surface of the battery 20 close to the second large surface positioning member can be expanded by the second shell expansion member 380. When the top cover 21 is press-fitted into the battery 20, the risk of interference between the large surface edge of the battery 20 close to the second large surface positioning member and the top cover 21 can be reduced, thereby reducing the risk of damage to the battery 20 during the press-fitting process.

[0080] Reference Figure 4 As shown, the first large surface positioning member 220 has a first positioning portion 221 and a second positioning portion 222. The first positioning portion 221 is used to abut against the top cover 21, and the second positioning portion 222 is used to abut against the battery 20. The first positioning portion 221 and the second positioning portion 222 are spaced apart along the third direction z, and an avoidance groove 223 is provided on the second positioning portion 222. The avoidance groove 223 is recessed along the third direction z in a direction away from the first positioning portion 221 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 large surface of the battery 20 and the top cover 21, the first positioning portion 221 can abut against the top cover 21, and the second positioning portion 222 can abut against one large surface of the battery 20, so that the battery 20 and the top cover 21 are positioned by the first positioning portion 221 and the second positioning portion 222 respectively. At the same time, since the first positioning portion 221 and the second positioning portion 222 are spaced apart along the third direction z, and the avoidance groove 223 is provided on the second positioning portion 222, Therefore, the top of the battery 20 can be located within the range of the avoidance groove 223 in the third direction z. Therefore, the avoidance 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 be deformed outward due to the squeezing of the top cover 21. The avoidance groove 223 can prevent the first positioning portion 221 of the first large surface positioning member 220 from interfering with the top of the deformed battery 20, thereby preventing the first large surface positioning member 220 from causing damage to the battery 20.

[0082] Specifically, refer to Figure 4 As shown, in the present embodiment, in the first direction x, the first positioning portion 221 is arranged closer to the battery than the second positioning portion 222. In order to enable the top cover 21 to be successfully pressed into the battery 20, when the top cover 21 is manufactured, the size of the top cover 21 is smaller than the size of the battery 20. When the first positioning portion 221 is arranged closer to the battery than the second positioning portion 222, the first positioning portion 221 can be abutted against the smaller top cover 21, and the second positioning portion 222 can be abutted against the larger battery 20, thereby realizing the positioning of the battery 20 and the top cover 21 by the first positioning portion 221 and the second positioning portion 222 respectively.

When the press-fitting part 631 presses the top cover 21, the liquid injection hole protection part 6315 is covered on the liquid injection hole to protect the liquid injection hole through the liquid injection hole protection part 6315, so as to prevent metal debris generated during the press-fitting process from entering the battery through the liquid injection hole, thereby preventing damage to the interior of the battery.

[0099] Continue to refer to Fig.14 As shown, the third press-fitting part 6313 is spaced from the second press-fitting part 6312 to define a second avoidance space 6316 between the second press-fitting part 6312 and the third press-fitting part 6313, a plurality of dust removal grooves 6317 are provided on the first press-fitting part 6311, and the press-fitting assembly 630 is also provided with a plurality of dust removal holes 632, each dust removal groove 6317 is connected to the first avoidance space 6314, and each dust removal groove 6317 is connected to a first avoidance space 6314 and to at least one dust removal hole 632, each dust removal hole 632 is externally connected to a vacuum dust extraction device, and in the process of press-fitting the top cover 21, the metal debris generated can enter the dust removal groove 6317 through the first avoidance space 6314 and the second avoidance space 6316, and be sucked away by the vacuum dust extraction device in the dust removal hole 632, so as to clear the metal debris generated in the press-fitting process and reduce the damage of the metal debris to the battery.

[0100] Continue to refer to Fig.14 As shown, each third press-fitting 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 press-fitting part 6313 can adsorb the edges of the two ends of the top cover 21 along the first direction x, that is, it can adsorb the middle part of the long side of the top cover 21 to offset the partial squeezing force of the press-fitting part 631 on the long side of the top cover 21, and avoid the top cover 21 being broken by the press-fitting part 631 during the press-fitting process.

[0101] Reference Fig.13As shown, the press-fitting mechanism 600 further includes a second limit member 640 and a guide member 650. The second limit member 640 and the press-fitting assembly 630 are respectively located on both sides of the press-fitting frame 610 along the third direction z. The second limit member 640 is arranged on the press-fitting frame 610 and protrudes from the press-fitting frame 610 along the third direction z in a direction away from the press-fitting assembly 630. A guide hole is provided on the press-fitting frame 610, and the guide member 650 is passed through the guide hole. In the third direction z, one end of the guide member 650 is connected to the press-fitting assembly 630, and the other end of the guide member 650 is spaced apart from one end of the second limit member 640 away from the press-fitting frame 610 along the third direction z. When the eleventh driving member 620 drives the press-fitting assembly 630 along the third direction z When moving and approaching the top cover 21, the guide member 650 slides in the guide hole relative to the pressing frame 610 until the guide member 650 and the second limit member 640 abut against each other at one end away from the pressing frame 610. When the guide member 650 abuts against the second limit member 640, the second limit member 640 can stop the guide member 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 limit member 640 can limit the moving distance of the pressing assembly 630 along the third direction z, thereby preventing the pressing assembly 630 from moving too much along the third direction z to damage the battery, and at the same time preventing the pressing assembly 630 from causing damage to other structures of the pressing device and the safety of the operator.

[0102] Reference Fig.13 As shown, the pressing mechanism 600 includes a plurality of eleventh driving members 620 and a pressing assembly 630, wherein the plurality of pressing assemblies 630 are arranged at intervals along the first direction x, and each pressing assembly 630 is arranged corresponding to a feeding slot 110, and each eleventh driving member 620 is used to connect with a pressing assembly 630, and to drive the pressing assembly 630 connected thereto to move along the third direction z, so that each pressing assembly 630 can press-fit a top cover 21, thus, the pressing device of the present application can press-fit the top covers 21 of multiple batteries synchronously.

[0103] Specifically, in this embodiment, the clamping mechanism 500 also 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 loading groove 110, so as to facilitate the first large surface positioning mechanism 200, the second large surface positioning mechanism 300 and the small surface positioning mechanism 400 to position the top cover 21 and the shell 22 of the battery 20, and at the same time facilitate the pressing mechanism 600 to press the top cover 21.
