[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0027] See also Figure 1 The utility model proposes a clamping device 1000, which includes a plurality of clamping modules 100, which are arranged along a first direction to clamp the battery aluminum shell at multiple positions in the first direction. The position where the clamping module 100 clamps the battery aluminum shell is located at a position where the battery aluminum shell is 3mm away from the battery top cover. The clamping modules 100 can be spaced apart, or they can be tightly connected, which is not specifically limited here.

[0028] The battery aluminum shell has a length direction, a width direction and a height direction. The battery top cover is located on the surface of the battery aluminum shell in the height direction. The first direction can be the length direction, and the first direction can also be the width direction, which is not specifically limited here.

[0029] When using the clamping device 1000 to clamp the battery aluminum shell, the battery aluminum shell is first placed on the clamping module 100, and then the clamping module 100 works to clamp the battery. After the clamping module 100 contacts the battery aluminum shell, the clamping modules 100 located at both ends of the first direction contact the two ends of the battery aluminum shell in the first direction and remain stationary, and the clamping module 100 located in the middle will continue to drive the middle part of the battery aluminum shell to deform, and finally the clamping device 1000 maintains the clamping state of the battery aluminum shell.

[0030] The technical solution of the utility model, its clamping device 1000 includes a plurality of clamping modules 100, and the plurality of clamping modules 100 are arranged along the first direction to clamp the battery aluminum shell at multiple positions in the first direction. In this way, the middle of the battery shell is clamped by the clamping module 100 located in the middle, so that the middle of the battery shell can produce more deformation than the two ends of the battery shell under the drive of the clamping module 100 located in the middle, thereby reducing the gap between the middle of the battery shell and the battery top cover, thereby avoiding the large gap between the middle of the battery shell and the battery top cover, resulting in misjudgment of the relative position detection of the battery shell and the battery top cover, thereby improving the production efficiency of the battery.

[0031] It should be noted that the middle part of the battery shell can produce more deformation than the two ends of the battery shell under the drive of the clamping module 100 located in the middle. It can be understood that the clamping amplitude of the middle part of the battery shell by the clamping module 100 located in the middle is greater than the clamping amplitude of the two ends of the battery shell by the clamping modules 100 located at the two ends, so that the deformation of the clamped part of the middle part of the battery shell is greater than that of the two ends of the battery shell, thereby driving the middle part of the battery shell close to the battery top cover to move inward with the clamped part of the middle part of the battery shell, so as to reduce the gap between the outward-turned part of the middle part of the battery shell and the battery top cover.

[0032] Please also read Figure 1 to Figure 2 In some embodiments of the present utility model, the clamping module 100 includes a first clamping member 110, a second clamping member 120 and a first driving member 130. The first clamping member 110 and the second clamping member 120 are arranged opposite to each other. The first driving member 130 is connected to the corresponding first clamping member 110 to drive the first clamping member 110 to move in a direction close to or away from the corresponding second clamping member 120. In this way, the first driving member 130 drives the corresponding first clamping member 110 to move toward the corresponding second clamping member 120, so that the first clamping member 110 pushes the battery aluminum shell to move toward the second clamping member 120 until the battery aluminum shell abuts against the second clamping member 120, so that the first clamping member 110 and the second clamping member 120 cooperate to clamp the battery aluminum shell. There are many types of the first driving member 130. The first driving member 130 can be a telescopic motor or an air pump, which is not specifically limited here.

[0033] Furthermore, the clamping module 100 further includes two clamping parts 140, which are respectively convexly arranged on the two opposite surfaces of the first clamping member 110 and the second clamping member 120, and the clamping parts 140 are extended along the first direction and arranged close to the shell opening of the battery aluminum shell, and the clamping parts 140 of two adjacent clamping modules 100 are arranged in abutment. In this way, the contact surface between the clamping module 100 and the battery aluminum shell can be reduced by the contact between the clamping part 140 and the battery aluminum shell, thereby avoiding the clamping module 100 from causing a large range of deformation of the battery aluminum shell, resulting in a large change in the appearance of the battery aluminum shell.

[0034] The clamping part 140 can be made of many materials, such as metal, hard plastic, or other materials, which are not specifically limited here. The clamping part 140 can be installed in many ways, such as being integrally formed with the first clamping member 110 and the second clamping member 120, or being detachably installed on the first clamping member 110 and the second clamping member 120, which are not specifically limited here.

[0035] Considering that the rigid collision between the clamping module 100 and the battery aluminum shell is likely to cause wear to the battery aluminum shell, in view of this, please refer to Figure 1 to Figure 2 The clamping module 100 further includes two flexible members 150, which are respectively mounted on the two opposite surfaces of the two clamping parts 140 and are arranged close to the shell opening of the battery aluminum shell. With such arrangement, when the clamping module 100 contacts the battery aluminum shell, the flexible member 150 will first deform to reduce the impact force on the battery aluminum shell, thereby preventing the clamping module 100 from causing wear to the battery aluminum shell when the clamping module 100 contacts the battery aluminum shell. At the same time, the surface of the flexible member 150 is relatively soft, so as to avoid friction between the clamping module 100 and the battery aluminum shell, which may cause wear on the surface of the battery aluminum shell.

[0036] There are many types of the flexible member 150, the flexible member 150 can be sponge, the flexible member 150 can also be rubber, which is not specifically limited here. There are many ways to install the flexible member 150, the flexible member 150 can be installed on the clamping part 140 by pasting, the flexible member 150 can also be installed on the clamping part 140 by screw connection, and the flexible member 150 can also be installed on the clamping part 140 by other ways, which is not specifically limited here.

[0037] Please also read Figure 1 to Figure 2 In some embodiments of the present utility model, the clamping device 1000 further includes a second driving member 200, which is drivingly connected to the second clamping member 120 located in the middle, so as to drive the corresponding second clamping member 120 to move in a direction close to or away from the corresponding first clamping member 110. In this way, the second driving member 200 can drive the second clamping member 120 located in the middle to move, so that the second clamping member 120 can drive the middle part of the battery aluminum shell to produce more deformation, so as to avoid the flange of the middle part of the shell wall of the battery aluminum shell in contact with the second clamping member 120, resulting in a larger gap between the middle part of the shell wall of the battery aluminum shell in contact with the second clamping member 120 and the battery top cover, thereby reducing the gap between the middle part of the shell wall of the battery aluminum shell in contact with the second clamping member 120 and the battery top cover, so as to reduce the possibility of misjudgment of the relative position detection of the battery shell and the battery top cover, thereby improving the production efficiency of the battery. There are many types of the second driving member 200. The second driving member 200 may be a telescopic motor or an air pump, which is not specifically limited here.

[0038] Considering that the movement directions of the first clamping members 110 are different, it is easy to cause the first clamping members 110 to deform the battery aluminum shell in different directions, thereby affecting the relative position detection of the battery aluminum shell and the battery top cover. In view of this, please refer to Figure 1 to Figure 2The clamping device 1000 further includes a mounting plate 300, the mounting plate 300 is provided with a plurality of tracks 310, the tracks 310 are extended along the second direction, the plurality of tracks 310 are arranged at intervals along the first direction, and the second direction is perpendicular to the first direction; the first clamping member 110 is movably mounted on the corresponding track 310, and the second clamping member 120 is mounted on the mounting plate 300. In this arrangement, the guide rail can cooperate with the first clamping member 110, so that each first clamping member 110 moves along the second direction, thereby reducing the possibility of misjudgment of the relative position detection of the battery aluminum shell and the battery top cover, thereby improving the production efficiency of the battery.

[0039] It can be understood that when the first direction corresponds to the length direction of the battery aluminum shell, the second direction corresponds to the width direction of the battery aluminum shell; when the first direction corresponds to the width direction of the battery aluminum shell, the second direction corresponds to the length direction of the battery aluminum shell.

[0040] Further, the mounting plate 300 is provided with a plurality of mounting portions 320, the plurality of mounting portions 320 are arranged in a row in the first direction and the second direction, and the second clamping member 120 is detachably mounted on the mounting portion 320. In this arrangement, the first clamping portion 140 and the second clamping portion 140 can clamp battery aluminum shells of different sizes by installing the second clamping member 120 on the mounting portions 320 at different positions, thereby improving the practicality of the clamping device 1000.

[0041] It should be noted that if the second direction is the width direction of the battery aluminum shell, the second clamping member 120 is removed from the mounting portion 320 and then installed on the mounting portions 320 at different positions in the second direction to adapt to battery aluminum shells of different widths. If the width of the battery aluminum shell increases, the second clamping member 120 is installed on the mounting portion 320 away from the first clamping member 110. If the width of the battery aluminum shell decreases, the second clamping member 120 is installed on the mounting portion 320 of the first clamp of the frame. The mounting portions 320 are arranged in a row so that each second clamping portion 140 can be installed on each mounting portion 320, so that the second clamping portion 140 does not need to be installed on the mounting portion 320 specified in the first direction, thereby facilitating the assembly of the clamping device 1000 by the staff.

[0042] Please also read Figure 1 to Figure 2In some embodiments of the present invention, a first positioning protrusion 160 is convexly provided on the surface of the first clamping member 110 of at least one clamping module 100 facing the second clamping member 120, and a second positioning protrusion 170 is convexly provided on the surface of the corresponding second clamping member 120 facing the first positioning protrusion 160. The first positioning protrusion 160 and the second positioning protrusion 170 are used to clamp and position the battery top cover. With such a configuration, when the clamping device 1000 clamps the battery aluminum shell, the first positioning protrusion 160 and the second positioning protrusion 170 can be used to position the battery top cover, so that the battery aluminum shell and the battery top cover can better pass the relative position detection, thereby improving the production efficiency of the battery.

[0043] The first positioning protrusion 160 may be integrally formed with the first clamping member 110, or may be detachably mounted on the first clamping member 110, which is not specifically limited here. The second positioning protrusion 170 may be integrally formed with the second clamping member 120, or may be detachably mounted on the second clamping member 120, which is not specifically limited here.

[0044] Please also read Figures 1 to 3 In some embodiments of the utility model, the surface of the clamping module 100 close to the shell opening of the battery aluminum shell is provided with an abutting convex portion 180, and the abutting convex portion 180 abuts against the battery aluminum shell. In this way, the abutting convex portion 180 abuts against the side of the battery aluminum shell close to the battery top cover, thereby reducing the deformation degree of the battery aluminum shell flange, thereby reducing the gap between the battery aluminum shell and the battery top cover, thereby avoiding the large gap between the middle of the battery shell and the battery top cover, resulting in misjudgment of the relative position detection of the battery shell and the battery top cover, thereby improving the production efficiency of the battery.

[0045] For further information, see Figure 3 The clamping module 100 is provided with a plurality of mounting holes 190, and the plurality of mounting holes 190 are arranged at intervals along the first direction, and the abutting protrusion 180 is detachably mounted on the mounting holes 190. In this way, by installing the abutting protrusion 180 on the mounting holes 190 at different positions, the abutting protrusion 180 can be adapted to battery aluminum shells of different sizes, thereby improving the practicality of the clamping device 1000.

[0046] It should be noted that if the first direction is the length direction of the battery aluminum shell, the abutment protrusion 180 is installed in the mounting holes 190 at different positions in the first direction to adapt to battery aluminum shells of different lengths, thereby ensuring that the abutment protrusion 180 can abut against the designated position of the battery aluminum shell. If the length of the battery aluminum shell increases, the abutment protrusion 180 is moved toward the end of the clamping device 1000. If the length of the battery aluminum shell decreases, the abutment protrusion 180 is moved toward the middle of the clamping device 1000.

[0047] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
