[0063] The embodiment of the present application discloses a pressing head and a pressing device, which enables the pressing head to adapt to top covers of different sizes, thereby effectively improving the production efficiency of batteries of different models.

[0064] The technical solution of the present application will be described in detail below with reference to specific embodiments and drawings.

[0065] The present application embodiment provides a pressure head, such as Figure 1-Figure 7 As shown, the pressing head 42 is used to press the top cover 01 into the battery housing 02, and includes a main body 1 and multiple groups of extrusion protrusion groups 2. The main body 1 has a first surface 11 facing the top cover 01, and the first surface 11 is provided with an avoidance groove 12, and the avoidance groove 12 is used to avoid the protrusion structure on the top cover 01; and the multiple groups of extrusion protrusion groups 2 are arranged on the first surface 11 and are located at the periphery of the avoidance groove 12. The extrusion protrusion group 2 includes at least one extrusion protrusion, and the heights of the extrusion protrusions in the same extrusion protrusion group 2 are the same, and the heights of the extrusion protrusions in different extrusion protrusion groups 2 are different. The multiple groups of extrusion protrusion groups 2 are used to press the top covers 01 of different sizes.

[0066] In this embodiment, multiple groups of extrusion protrusion groups 2 are arranged on the first surface 11 and are located at the periphery of the avoidance groove 12. The extrusion protrusion group 2 includes at least one extrusion protrusion. The heights of the extrusion protrusions in the same extrusion protrusion group 2 are the same, and the heights of the extrusion protrusions in different extrusion protrusion groups 2 are different. Multiple groups of extrusion protrusion groups 2 are used to press-fit top covers 01 of different sizes, so that each group of extrusion protrusion groups 2 can be adapted to a top cover 01 of one size to press-fit the adapted top cover 01 into the battery shell 02, that is, the pressing head 42 can be adapted to top covers 01 of different sizes to press-fit top covers 01 of different sizes into the battery shell 02. Compared with a pressing head 42 that only adapts to a top cover 01 of one size, when pressing the top cover 01 of batteries of different sizes and models into the battery shell 02, there is no need to replace a top cover 01 of one size with a corresponding pressing head 42, which saves time and effort and effectively improves the production efficiency of batteries of different models.

[0067] In addition, an avoidance groove 12 is provided on the first surface 11 of the pressing head 42 facing the top cover 01. The avoidance groove 12 is used to avoid the raised structure on the top cover 01. When the top cover 01 is pressed into the battery housing 02 by the pressing head 42, the pressing head 42 can be effectively prevented from squeezing the raised structure on the top cover 01, thereby improving the pressing effect of the pressing head 42 on the top cover 01.

[0068] It should be understood that the extrusion protrusions mentioned above can be used to press the edge of the top cover 01 when the top cover 01 is pressed. The protrusion structure on the top cover 01 mentioned above can be a protruding structure such as a pole or a sealing plug on the top cover 01.

[0069] The number of the extrusion protrusion groups 2 can be two, three or more, which is not limited here.

[0070] The extrusion protrusion group 2 includes at least one extrusion protrusion, that is, each extrusion protrusion group 2 may include one extrusion protrusion, or include two extrusion protrusions, or include more extrusion protrusions, which is not limited here and can be specifically set according to actual conditions.

[0071] When the extrusion protrusion group 2 includes one extrusion protrusion, the extrusion protrusion can be arranged around the avoidance groove 12, so that the extrusion protrusion can press the edge of the top cover 01, so that the extrusion protrusion group 2 can have a better press-fitting effect on the top cover 01. When the extrusion protrusion group 2 includes two or more extrusion protrusions, the two or more extrusion protrusions can be arranged at intervals on the periphery of the avoidance groove 12, so that the extrusion protrusion group 2 can press-fit the top cover 01 while making the weight of the pressure head 42 lighter.

[0072] You can choose, such as Figure 1-Figure 8As shown, the plurality of extrusion protrusion groups 2 include a first extrusion protrusion group 2a and a second extrusion protrusion group 2b, wherein the first extrusion protrusion group 2a and the second extrusion protrusion group 2b are respectively used for press-fitting width (such as Figure 6 The first top cover and the second top cover are different in the direction shown by x1.

[0073] Therefore, the pressing head 42 can press-fit the first top cover through the first extrusion protrusion group 2a, and press-fit the second top cover through the second extrusion protrusion group 2b, so that the pressing head 42 can adapt to the pressing of two top covers 01 with different widths. While improving the production efficiency of batteries with two different widths, the structure of the pressing head 42 can be relatively simple and easy to implement.

[0074] Wherein, for the first top cover and the second top cover of different widths, the length of the two can be (such as Figure 5 Of course, the lengths of the first top cover and the second top cover may be the same, which is not limited here.

[0075] Optionally, the width of the first top cover is smaller than the width of the second top cover, the first extrusion protrusion group 2a includes a plurality of first protrusions 21, the second extrusion protrusion group 2b includes a plurality of second protrusions 23, the plurality of first protrusions 21 are respectively located on both sides of the avoidance groove 12 along the width direction of the top cover 01, and are used to extrude the first top cover at opposite ends along the width direction of the top cover 01, the plurality of second protrusions 23 are respectively located on both sides of the plurality of first protrusions 21 along the width direction of the top cover 01, and are used to extrude the second top cover at opposite ends along the width direction of the top cover 01, the height of the second protrusion 23 is higher than the height of the first protrusion 21, and the height difference between the two is greater than or equal to the height of the protrusion structure on the top cover 01.

[0076] Thus, the first top cover 01 can be squeezed at two opposite ends along the width direction of the top cover 01 by multiple first protrusions 21, and the second top cover 01 can be squeezed at two opposite ends along the width direction of the top cover 01 by multiple second protrusions 23, so that the first protrusions 21 and the second protrusions 23 have a better pressing effect on the matching top cover 01 along the width direction of the top cover 01, and the arrangement of the multiple first protrusions 21 and the multiple second protrusions 23 on the first surface 11 along the width direction of the top cover 01 can be relatively simple, reducing the difficulty of setting the multiple first protrusions 21 and the multiple second protrusions 23.

[0077] Furthermore, the height of the second protrusion 23 is higher than that of the first protrusion 21 , and the height difference between the two is greater than or equal to the height of the protrusion structure on the top cover 01 , which can effectively prevent the interference between the multiple first protrusions 21 and the second top cover when the second top cover is press-fitted by multiple second protrusions 23 .

[0078] The number of the first protrusions 21 may be two, three or more, which is not limited here. The number of the second protrusions 23 may also be two, three or more, which is not limited here.

[0079] Optionally, the length of the first top cover is the same as that of the second top cover; the first extrusion protrusion group 2a also includes a third protrusion 22, which is arranged on at least one side of the avoidance groove 12 on opposite sides along the length direction of the top cover 01, and is used to extrude at least one of the two opposite ends of the first top cover along the length direction of the top cover 01, and the height of the third protrusion 22 is the same as the height of the first protrusion 21; the second extrusion protrusion group 2b also includes a plurality of fourth protrusions 24, which are located on opposite sides of the third protrusion 22 along the width direction of the top cover 01, and are used to extrude at least one of the two opposite ends of the second top cover along the length direction of the top cover 01, and the height of the fourth protrusion 24 is the same as the height of the second protrusion 23.

[0080] Thus, the third protrusion 22 can be used to press at least one of the two opposite ends of the first top cover along the length direction of the top cover 01, and the plurality of fourth protrusions 24 can be used to press at least one of the two opposite ends of the second top cover along the length direction of the top cover 01, so that the pressing head 42 can press-fit two top covers 01 with different widths and the same length, and the third protrusion 22 and the fourth protrusion 24 can have a good press-fitting effect on the matching top cover 01 along the length direction of the top cover 01, thereby having a good press-fitting effect on the top cover 01. In addition, the arrangement of the third protrusion 22 and the plurality of fourth protrusions 24 on the first surface 11 along the length direction of the top cover 01 can be relatively simple, reducing the difficulty of setting the third protrusion 22 and the plurality of fourth protrusions 24.

[0081] Among them, the third protrusion 22 is arranged on at least one side of the two opposite sides of the avoidance groove 12 along the length direction of the top cover 01, that is, the third protrusion 22 can be arranged on one side of the two opposite sides of the avoidance groove 12 along the length direction of the top cover 01, or the third protrusion 22 can be arranged on both sides of the avoidance groove 12 along the length direction of the top cover 01, which is not limited here.

[0082] In addition, the number of the third protrusions 22 may be one, two or more, which is not limited here. The number of the fourth protrusions 24 may also be two, three or more, which is not limited here.

[0083] The first surface 11 is a rectangular structure, the first protrusion 21 and the second protrusion 23 both extend along the length direction of the first surface 11, the third protrusion 22 extends along the width direction of the first surface 11, and the fourth protrusion 24 is arranged at a corner of the first surface 11, and a portion of the fourth protrusion 24 extends along the length direction of the first surface 11, and another portion extends along the width direction of the first surface 11.

[0084] Thus, the structures of the first protrusion 21, the second protrusion 23, the third protrusion 22 and the fourth protrusion 24 are relatively simple and easy to implement, and both the first top cover and the second top cover can be pressed along the length direction and the width direction of the first surface 11, which has a better pressing effect.

[0085] The length direction of the first surface 11 may be parallel to the length direction of the top cover 01 , and the width direction of the first surface 11 may be parallel to the width direction of the top cover 01 .

[0086] In addition, the first protrusion 21 and the second protrusion 23 may be rectangular structures or elliptical structures extending along the length direction of the first surface 11, the third protrusion 22 may be a rectangular structure or a rectangular-like structure extending along the width direction of the first surface 11, and the fourth protrusion 24 may be an L-shaped structure or a T-shaped structure, which is not limited here.

[0087] Alternatively, if Figure 8-Figure 16 As shown, the width of the first top cover is smaller than the width of the second top cover, and the length of the first top cover is different from the length of the second top cover; the first extrusion protrusion group 2a also includes a third protrusion 22, and the third protrusion 22 is arranged on at least one side of the two opposite sides of the avoidance groove 12 along the length direction of the top cover 01, and is used to extrude at least one of the two opposite ends of the first top cover along the length direction of the top cover 01, and the height of the third protrusion 22 is the same as the height of the first protrusion 21; the second extrusion protrusion group 2b also includes a fourth protrusion 24, and the fourth protrusion 24 is staggered with the third protrusion 22 and the second protrusion 23 along the length direction of the top cover 01, and the fourth protrusion 24 is used to extrude at least one of the two opposite ends of the second top cover along the length direction of the top cover 01, and the height of the fourth protrusion 24 is the same as the height of the second protrusion 23.

[0088] Thus, the press head 42 can press-fit two types of top covers 01 with different widths and lengths, and the third protrusion 22 and the fourth protrusion 24 can have a good press-fitting effect on the matching top cover 01 along the length direction of the top cover 01, thereby having a good press-fitting effect on the top cover 01. In addition, the arrangement of the third protrusion 22 and the plurality of fourth protrusions 24 on the first surface 11 along the length direction of the top cover 01 can be relatively simple, reducing the difficulty of setting the third protrusion 22 and the plurality of fourth protrusions 24.

[0089] The length of the first top cover is different from the length of the second top cover. The length of the first top cover may be smaller than the length of the second top cover, or the length of the first top cover may be larger than the length of the second top cover, which is not limited here.

[0090] Optionally, when the length of the first top cover is greater than the length of the second top cover, along the length direction of the top cover 01, the distance between the fourth protrusion 24 and the center of the avoidance groove 12 (eg Figure 8 The distance shown in a1 in FIG. 1 is smaller than the distance between the third protrusion 22 and the center of the avoidance groove 12 (shown in FIG. Figure 8 Thus, the top cover 01 with a wider width and a shorter length can be pressed by the plurality of second protrusions 23 and the plurality of fourth protrusions 24, and the top cover 01 with a narrower width and a longer length can be pressed by the plurality of first protrusions 21 and the third protrusions 22.

[0091] The first extrusion protrusion group 2a may further include a fifth protrusion 25, which is located on the side of the third protrusion 22 facing the first protrusion 21, and the fifth protrusion 25 and the third protrusion 22 are spaced apart or formed together along the length direction of the top cover 01, and at least part of the fifth protrusion 25 is located between the fourth protrusion 24 and the avoidance groove 12. The height of the fifth protrusion 25 may be the same as that of the third protrusion 22.

[0092] Thus, the portion of the top cover 01 between the end and the middle along the length direction thereof can be press-fitted by the fifth protrusion 25 , so that the press-fitting effect of the press head 42 on the top cover 01 can be better.

[0093] At least part of the fifth protrusion 25 is located between the fourth protrusion 24 and the avoidance groove 12. It may be that a part of the fifth protrusion 25 is located between the fourth protrusion 24 and the avoidance groove 12, and the other part is located on the side of the fourth protrusion 24 facing the third protrusion 22; it may also be that the entire fifth protrusion 25 is located between the fourth protrusion 24 and the avoidance groove 12; it may also be that a part of the fifth protrusion 25 is located between the fourth protrusion 24 and the avoidance groove 12, and the other part is located on the side of the fourth protrusion 24 facing the first protrusion 21, which is not limited here.

[0094] In addition, when the width of the first top cover is smaller than that of the second top cover and the length of the first top cover is the same as that of the second top cover, a fifth protrusion 25 may be provided on the side of the third protrusion 22 facing the first protrusion 21 , and the fifth protrusion 25 has the same height as that of the first protrusion 21 .

[0095] The present application also discloses a press-fitting device, such as Figure 17-Figure 19 As shown, the battery housing 02 has a first direction (such as Fig.18 The two first side walls opposite to each other along the direction indicated by y1 in FIG. Fig.18The press-fitting device 10 comprises a base 3, a pressing mechanism 4 and a centering mechanism 5. The base 3 has a bearing surface 31, and the bearing surface 31 is used to bear the battery to be pressed into the battery housing 02. The pressing mechanism 4 comprises a pressing drive 41 and a pressing head 42 of any one of the above embodiments. The pressing head 42 is movably arranged on the base 3. The pressing drive 41 is used to drive the pressing head 42 to move toward or away from the bearing surface 31. The centering mechanism 5 is arranged on the base 3, and comprises a first positioning component 51 and a second positioning component 52. The first positioning component 51 is used to abut against the two first side walls of the battery housing 02 so that the top cover 01 corresponds to the pressing head 42 in the first direction. The second positioning component 52 is used to abut against the two second side walls of the battery housing 02 so that the top cover 01 corresponds to the pressing head 42 in the second direction.

[0096] In this embodiment, the first positioning component 51 is used to abut against the two first side walls of the battery housing 02 so that the top cover 01 corresponds to the pressure head 42 in the first direction, and the second positioning component 52 is used to abut against the two second side walls of the battery housing 02 so that the top cover 01 corresponds to the pressure head 42 in the second direction. The first positioning component 51 can be used to limit the position of the battery to be pressed into the battery housing 02 along the first direction on the bearing surface 31, and the second positioning component 52 can be used to limit the position of the battery to be pressed into the battery housing 02 along the first direction on the bearing surface 31. The position of the second direction is to enable the battery to be pressed into the battery housing 02 with the top cover 01 to correspond to the pressing head 42, so that when the pressing drive 41 drives the pressing head 42 to move in the direction close to the bearing surface 31, the top cover 01 can be pressed into the battery housing 02, and after the press-fitting of the top cover 01 is completed, the pressing head 42 can be driven by the pressing drive 41 to move in the direction away from the bearing surface 31, so as to facilitate the removal of the pressed battery from the bearing surface 31, and place the subsequent battery to be pressed into the battery housing 02 with the top cover 01 on the bearing surface 31 for press-fitting operation.

[0097] Moreover, the pressing head 42 in the pressing device 10 is the pressing head 42 in the above-mentioned embodiments. Therefore, the pressing head 42 in the pressing device 10 has substantially the same technical effect as the pressing head 42 in the above-mentioned embodiments. Since the above-mentioned embodiments have described the pressing head 42 in relatively detail, it will not be repeated here.

[0098] The pressing driving member 41 may be any one of a pneumatic cylinder, an electric cylinder, a combination of a motor and a gear rack, etc., and is not limited here.

[0099] In addition, when the battery is a square battery, that is, the battery housing 02 is a rectangular structure, the first direction may be the width direction of the battery housing 02, that is, the width direction of the top cover 01, and the second direction may be the length direction of the battery housing 02, that is, the length direction of the top cover 01. Of course, the battery may also be a battery of other shapes, such as a circular structure, which is not limited here. The following is a detailed description taking the battery housing 02 as a rectangular structure as an example.

[0100] The above-mentioned first positioning component 51 can have a variety of implementation methods. In one possible implementation method, the first positioning component 51 may include a first cylinder and a second cylinder relatively arranged on both sides of the bearing surface 31 along the first direction, and the telescopic end of the first cylinder and the telescopic end of the second cylinder are respectively used to abut against the two first side walls of the battery, so that the structure of the first positioning component 51 is simple and easy to implement.

[0101] In another possible implementation, Fig.18 and Fig.19 As shown, the first positioning assembly 51 includes a first adjusting drive member 511, a first abutting module 512, a second adjusting drive member 513 and a second abutting module 514. The first abutting module 512 and the second abutting module 514 are movably arranged on both sides of the bearing surface 31 along the first direction. The first abutting module 512 and the second abutting module 514 are respectively used to abut the two first side walls. The first adjusting drive member 511 is connected to the first abutting module 512 for driving the first abutting module 512 to move along the first direction. The second adjusting drive member 513 is connected to the second abutting module 514 for driving the second abutting module 514 to move along the first direction.

[0102] Thus, the position of the first abutment module 512 along the first direction and the position of the second abutment module 514 along the first direction can be adjusted, so that the spacing between the first abutment module 512 and the second abutment module 514 can be adjusted, and can have a larger adjustment range, so that the first abutment module 512 and the second abutment module 514 can limit the battery shell 02 with different sizes along the first direction, so that the centering mechanism 5 can fix batteries with different sizes along the first direction, and cooperate with the corresponding pressing head 42 to press the top cover 01 on batteries with different sizes along the first direction, thereby improving the pressing efficiency of the pressing device 10 for batteries of different models.

[0103] The first adjusting drive member 511 may be any one of a cylinder, an electric cylinder, a hydraulic cylinder, a combination of a motor and a screw nut, etc., which is not limited here. The structure of the second adjusting drive member 513 may be substantially the same as that of the first adjusting drive member 511, and will not be described in detail here.

[0104] Of course, in other embodiments, the first positioning assembly 51 may include a first adjusting drive member 511, a first abutting module 512 and a second abutting module 514. The first abutting module 512 is movably arranged on one side of the bearing surface 31 along the first direction, and the second abutting module 514 is fixedly arranged on the other side of the bearing surface 31. The first abutting module 512 and the second abutting module 514 are respectively used to abut the two first side walls. The first adjusting drive member 511 is connected to the first abutting module 512, and is used to drive the first abutting module 512 to move along the first direction toward or away from the second abutting module 514. Similarly, the pressing device 10 can perform a pressing operation on the top cover 01 of batteries with different sizes along the first direction, and can also reduce the number of components in the first positioning assembly 51, thereby reducing costs.

[0105] In addition, the first abutment module 512 includes a first positioning driving member 5121 and a first abutment member 5122. The first positioning driving member 5121 is connected to the driving end of the first adjusting driving member 511. The driving end of the first positioning driving member 5121 is connected to the first abutment member 5122 for driving the first abutment member 5122 to abut against the opposite first side wall.

[0106] Thus, the first positioning driving member 5121 can drive the first abutment member 5122 to extend a corresponding distance, that is, to abut against the corresponding first side wall, so that the driving operation of the first positioning driving member 5121 on the first abutment member 5122 is simple and easy to implement, and coordinated with the driving of the first adjusting driving member 511, the moving distance of the first abutment member 5122 along the first direction can be larger, so that the limiting dimension of the first positioning component 51 along the first direction has a larger range, so that a variety of batteries with large size differences along the first direction can also be press-fitted by the press-fitting device 10, thereby improving the practicability of the press-fitting device 10.

[0107] Among them, the implementation method of the first positioning driver 5121 can be roughly the same as the implementation method of the first adjusting driver 511. The details can be referred to above and will not be repeated here.

[0108] In addition, the first abutment member 5122 can be any one of an abutment block, an abutment plate, an abutment bracket, etc., and is not limited here.

[0109] The implementation of the second abutting module 514 may be substantially the same as or different from the implementation of the first abutting module 512 , which is not limited here.

[0110] Optionally, when the implementation method of the second abutment module 514 is different from the implementation method of the first abutment module 512, the second abutment module 514 includes a second abutment member 5141, and the second abutment member 5141 is respectively arranged on both sides of the bearing surface 31 along the first direction with the first abutment member 5122, and the second abutment member 5141 is used to abut against the other opposite first side wall.

[0111] Therefore, the second abutment 5141 can be abutted against the other first side wall and cooperated with the first abutment 5122 to achieve limiting and fixing the battery housing 02 along the first direction, so that the battery is not prone to shaking or moving along the first direction, thereby improving the pressing effect of the pressing device 10 on the top cover 01, and the structure of the second abutment 5141 can be relatively simple, thereby reducing costs.

[0112] Among them, the structure of the second abutment 5141 can be roughly the same as the structure of the first abutment 5122, so that the two can have good interchangeability when assembling the first abutment 5122 and the second abutment 5141, thereby reducing the difficulty of installing the first abutment 5122 and the second abutment 5141.

[0113] Optionally, the first positioning assembly 51 further includes a first limiting module 515 and a second limiting module 516, wherein the first limiting module 515 is used to limit the moving distance of the first abutting module 512 along the first direction, and the second limiting module 516 is used to limit the moving distance of the second abutting module 514 along the first direction. Thus, the moving accuracy of the first abutting module 512 and the second abutting module 514 along the first direction can be effectively improved, so that the abutment of the first abutting module 512 and the second abutting module 514 against the two first side walls can be made with higher accuracy.

[0114] The first position-limiting module 515 may include a first position-limiting member 5151 and a second position-limiting member 5152. Two first position-limiting members 5151 are arranged on the base 3 along the first direction at intervals. The second position-limiting member 5152 is arranged on the first contact module 512. When the first adjusting driving member 511 drives the first contact module 512 to move along the first direction, the second position-limiting member 5152 can move between the two first position-limiting members 5151. Alternatively, the second position-limiting module 516 may include a third position-limiting member 5161 and a fourth position-limiting member 5162. Two third position-limiting members 5161 are arranged on the base 3 along the first direction at intervals. The fourth position-limiting member 5162 is arranged on the second contact module 514. When the second adjusting driving member 513 drives the second contact module 514 to move along the first direction, the fourth position-limiting member 5162 can move between the two third position-limiting members 5161. Alternatively, the first limiting module 515 may include a first limiting member 5151 and a second limiting member 5152, two first limiting members 5151 are arranged opposite to each other along the first direction on the base 3, and the second limiting member 5152 is arranged on the first abutting module 512. When the first adjusting driving member 511 drives the first abutting module 512 to move along the first direction, the second limiting member 5152 can move between the two first limiting members 5151, and the second limiting module 516 may include a third limiting member 5161 and a fourth limiting member 5162, two third limiting members 5161 are arranged opposite to each other along the first direction on the base 3, and the fourth limiting member 5162 is arranged on the second abutting module 514. When the second adjusting driving member 513 drives the second abutting module 514 to move along the first direction, the fourth limiting member 5162 can move between the two third limiting members 5161.

[0115] The cooperation between the second limiting member 5152 and the two first limiting members 5151 can limit the moving distance of the first abutment module 512 driven by the first adjusting driving member 511 in the first direction, and the cooperation between the fourth limiting member 5162 and the two third limiting members 5161 can limit the moving distance of the second abutment module 514 driven by the second adjusting driving member 513 in the first direction, so that the structures of the first limiting module 515 and the second limiting module 516 can be relatively simple and easy to implement.

[0116] The first stopper 5151 may be any one of a stopper block, a stopper plate, a stopper column, etc., which is not limited here. The structure of the second stopper 5152 may be substantially the same as that of the first stopper 5151, which will not be described in detail here. The structure of the third stopper 5161 may be substantially the same as that of the first stopper 5151, which will not be described in detail here. The structure of the fourth stopper 5162 may also be substantially the same as that of the first stopper 5151, which will not be described in detail here.

[0117] In addition, the second position-limiting member 5152 is disposed on the first abutting module 512, and may be disposed on the first positioning driving member 5121, or on the first abutting member 5122, which is not limited here. The fourth position-limiting member 5162 is disposed on the second abutting module 514, and may be disposed on the second abutting member 5141, or on other components in the second abutting module 514, which is not limited here.

[0118] In other embodiments, the first limit module 515 may also include a distance sensor, which is disposed on the first abutment module 512, and the distance sensor may be electrically connected to the first adjustment drive member 511, so that when the distance sensor measures that the first abutment module 512 moves to a preset distance, a signal can be transmitted to the first adjustment drive member 511, causing the first adjustment drive member 511 to stop driving the first abutment module 512.

[0119] The implementation method of the second positioning component 52 may be substantially the same as or different from the implementation method of the first positioning component 51 , which is not limited here.

[0120] In some embodiments, the second positioning assembly 52 includes a third positioning drive member 521 and two third abutment members 522. The two third abutment members 522 are respectively movably arranged on both sides of the supporting surface 31 along the second direction. The third positioning drive member 521 is respectively connected to the two third abutment members 522 for driving the two third abutment members 522 to move along the second direction so that the two third abutment members 522 respectively abut against the two second side walls.

[0121] Thus, the extended positions of the two third abutment members 522 along the second direction can be adjusted, so that the two third abutment members 522 can limit the battery shells 02 of different sizes along the second direction, so that the centering mechanism 5 can fix batteries of different sizes along the second direction, and cooperate with the corresponding pressing head 42 to press-fit the top cover 01 of batteries of different sizes along the second direction, thereby further improving the pressing efficiency of the pressing device 10 for batteries of different models.

[0122] The third positioning driver 521 may include any one of a cylinder, an electric cylinder, a combination of a motor and a gear rack, etc., which is not limited here. When the third positioning driver 521 includes an electric cylinder, the third positioning driver 521 can have a higher driving accuracy, so that the third abutting member 522 can have a higher moving accuracy along the second direction, so that the third abutting member 522 can abut and limit the battery housings 02 of different sizes along the second direction more accurately.

[0123] Optionally, the number of the third positioning driving members 521 can be two, and the two third positioning driving members 521 are respectively connected to the two third abutting members 522. Thus, the movement of the two third abutting members 522 along the second direction can be controlled separately, which reduces the difficulty of controlling the movement of the third abutting members 522 along the second direction.

[0124] In addition, the structure of the third abutment member 522 may be substantially the same as the structure of the first abutment member 5122 , and details may be referred to above, which will not be described again.

[0125] Suction cups may also be provided on the base 3, and suction cups are provided on both sides of the bearing surface 31 along the first direction. The suction cups are used to absorb the two first side walls of the battery housing 02, so that when the top cover 01 is pressed by the pressing head 42, the two suction cups can absorb the first side walls and pull them in opposite directions, so that the two first side walls can have a certain deformation in the first direction, that is, the opening of the battery housing 02 can be slightly opened, so that the top cover 01 can be pressed in more easily, thereby improving the efficiency of pressing the top cover 01. It should be understood that the suction cup absorbs the first side walls and pulls them, which can only cause the two first side walls to have some deformation in opposite directions.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
