Description

Technical Field

[0001] The present application relates to a positioning tool, and in particular to an assembly positioning tool and a battery production system. Background Art

[0002] When assembling the battery module and the water-cooling plate, due to the small position deviation between the battery module and the water-cooling plate, the problem of position deviation is easy to occur during the assembly process. Utility Model Content

[0003] In view of the above problems, the present application provides an assembly positioning tool and a battery production system, which can improve the problem of excessive positioning during the assembly process of battery modules and water cooling plates.

[0004] In a first aspect, the present application provides an assembly positioning tool, comprising:

[0005] Base assembly;

[0006] A first clamping assembly is arranged on the base assembly, the first clamping assembly includes a first clamping mechanism and a first positioning member, the first clamping mechanism and the first positioning member are arranged at intervals along a first direction, the first clamping mechanism has a first movable end and a second movable end, the first movable end is used to separately press the first to-be-assembled component onto the first positioning member along the first direction, and the second movable end is used to separately press the second to-be-assembled component onto the first positioning member along the first direction;

[0007] The second clamping assembly is arranged on the base assembly, and the second clamping assembly includes a second clamping mechanism and a second positioning member. The second clamping mechanism and the second positioning member are spaced apart along the second direction. The second clamping mechanism has a third movable end and a fourth movable end. The third movable end is used to press the first part to be assembled to the second positioning member alone along the second direction, and the fourth movable end is used to press the second part to be assembled to the second positioning member alone along the second direction. The first direction is different from the second direction.

[0008] The first movable end can press the first part to be assembled against the first positioning part alone, and the second movable end can press the second part to be assembled against the first positioning part alone. The first part to be assembled can be a battery module, and the second part to be assembled can be a water-cooling plate. The battery module and the water-cooling plate are both individually against the first positioning part, which can reduce the probability that the battery module or the water-cooling plate does not abut against the first positioning part, thereby improving the assembly accuracy of the battery module and the water-cooling plate along the first direction. At the same time, the third movable end can press the battery module against the second positioning part alone, and the fourth movable end is used to press the water-cooling plate against the second positioning part alone, which can reduce the probability that the battery module or the water-cooling plate does not abut against the second positioning part, thereby improving the assembly accuracy of the battery module and the water-cooling plate along the second direction.

[0009] In some embodiments, the first clamping mechanism includes a first clamping member and a second clamping member, the first clamping member forms a first movable end along a first direction toward one end of the first positioning member, the second clamping member is slidably connected to the base assembly along the first direction, the first clamping member and the second clamping member are slidably connected along the first direction, and the second clamping member forms a second movable end toward one end of the first positioning member.

[0010] During the clamping and positioning process of the first and second parts to be assembled, the first and second parts to be assembled can be manually pushed to move along the first direction, so that the first and second parts to be assembled are respectively pressed against the first positioning part, and the first positioning part positions the first and second parts to be assembled along the first direction. Therefore, the first pressing part presses the first part to be assembled against the first positioning part, and the second pressing part presses the second part to be assembled against the first positioning part, which can improve the assembly accuracy of the first and second parts to be assembled along the first direction.

[0011] In some embodiments, the first clamping mechanism also includes a first driving component and a first elastic component, the second clamping component is elastically connected to the first clamping component through the first elastic component, and the first driving component is used to drive one of the first clamping component and the second clamping component to move relative to the base assembly along the first direction.

[0012] The second pressing member is elastically connected to the first pressing member, and the first driving member drives the first pressing member to move, so as to press the first part to be assembled against the first positioning member, and at the same time, the second pressing member moves under the elastic force of the first elastic member, so as to press the second part to be assembled against the first positioning member, or the first driving member drives the second pressing member to move, so as to press the second pressing member against the second part to be assembled, and at the same time, the first pressing member moves under the elastic force of the first elastic member, so as to press the first part to be assembled against the first positioning member, thereby realizing the separate clamping and positioning of the first part to be assembled and the second part to be assembled (the first part to be assembled is clamped and positioned by the first pressing member, and the second part to be assembled is clamped and positioned by the second pressing member), so as to improve the assembly accuracy of the first part to be assembled and the second part to be assembled; at the same time, compared with the manual operation method, it saves more manpower and can maintain the positioning state of the first part to be assembled and the second part to be assembled.

[0013] In some embodiments, the first clamping member is inserted into the second clamping member and is drivingly connected to the first driving member. The first elastic member is located on the side of the second clamping member away from the first positioning member. One end of the first elastic member abuts against the second clamping member, and the other end of the first elastic member abuts against the first clamping member.

[0014] When the first driving component drives the first clamping member to move and press the first part to be assembled against the first positioning member, the first elastic member is compressed, and under the action of the elastic force, the second clamping member is driven to press the second part to be assembled against the first positioning member, so as to realize the separate clamping of the first clamping member on the first part to be assembled, and the separate clamping of the second clamping member on the second part to be assembled, so that the first part to be assembled and the second part to be assembled can both abut against the first positioning member, thereby improving the assembly accuracy of the first part to be assembled and the second part to be assembled along the first direction.

[0015] In some embodiments, along the first direction, one end of the first elastic member abuts against the surface of the second clamping member facing the first positioning member, the other end of the first elastic member abuts against the first clamping member, and the first driving member is drivingly connected to the second clamping member.

[0016] When the first driving component drives the second clamping component to move and presses the second part to be assembled against the first positioning component, the first elastic component is compressed, and under the action of the elastic force, the first clamping component is driven to press the first part to be assembled against the first positioning component, so as to realize the separate clamping of the first clamping component on the first part to be assembled, and the separate clamping of the second clamping component on the second part to be assembled, so that the first part to be assembled and the second part to be assembled can both abut against the first positioning component, thereby improving the assembly accuracy of the first part to be assembled and the second part to be assembled along the first direction.

[0017] In some embodiments, the assembly positioning tool also includes a second elastic member, which is located on the side of the second clamping member facing the positioning member, one end of the second elastic member abuts against the second clamping member, and the other end of the second elastic member abuts against the base assembly, and the stiffness of the second elastic member is less than the stiffness of the first elastic member. When the first clamping member and the second clamping member are in a clamped state, the first elastic member and the second elastic member are both in a compressed state.

[0018] The driving end of the first driving component can be abutted against or spaced from the first pressing member or the second pressing member. When the driving end of the first driving component moves in the direction opposite to the clamping direction, the first pressing member and the second pressing member release the first and second parts to be assembled under the elastic force of the second elastic member, so as to facilitate the removal of the first and second parts to be assembled and to be assembled and used next time. The stiffness of the first elastic member is greater than that of the second elastic member, so that the first and second parts to be assembled can be clamped under the elastic force difference between the first and second elastic members, so that the first and second parts to be assembled can be clamped and positioned separately.

[0019] In some embodiments, the second pressing member comprises:

[0020] A first connection portion, slidably connected to the base assembly along a first direction;

[0021] A second connecting portion is connected to the first connecting portion and is slidably connected to the first pressing member along a first direction, and the second connecting portion is elastically connected to the first pressing member via a first elastic member;

[0022] The pressing part is connected to the first connecting part, and one end of the pressing part facing the first positioning member forms a second movable end.

[0023] Thus, the movable connection between the second pressing member and the first pressing member and the sliding connection between the second pressing member and the base assembly are facilitated.

[0024] In some embodiments, the second clamping mechanism includes a third clamping member and a fourth clamping member, the fourth clamping member is slidably connected to the base assembly along the second direction, the fourth clamping member is slidably connected to the third clamping member along the second direction, and the fourth clamping member forms a fourth movable end toward one end of the second positioning member.

[0025] During the clamping and positioning process of the first and second parts to be assembled, the third pressing member and the fourth pressing member can be manually pushed to move along the first direction, so that the first and second parts to be assembled are respectively pressed against the second positioning member, and the third positioning member positions the first and second parts to be assembled along the second direction. Therefore, the third pressing member presses the first part to be assembled against the second positioning member, and the fourth pressing member presses the second part to be assembled against the second positioning member, which can improve the assembly accuracy of the first and second parts to be assembled along the second direction.

[0026] In some embodiments, the second clamping mechanism also includes a third elastic member and a second driving member, one end of the third elastic member abuts against the surface of the third clamping member facing the second positioning member, the other end of the third elastic member abuts against the fourth clamping member, and the second driving member is drivingly connected to the third clamping member for driving the third clamping member to move along the second direction.

[0027] The second driving component can drive the third clamping member to move to clamp and position the first part to be assembled. At the same time, the movement of the third clamping member compresses the third elastic member, pushing the fourth clamping member to press the second part to be assembled against the second positioning member, thereby realizing the separate clamping and positioning of the first part to be assembled and the second part to be assembled.

[0028] In some embodiments, the assembly positioning tool also includes a fourth elastic member, which is located on the side of the third clamping member away from the second positioning member, one end of the fourth elastic member abuts against the base assembly, and the other end of the fourth elastic member abuts against the third clamping member.

[0029] The third clamping member and the fourth clamping member can clamp the first to-be-assembled part and the second to-be-assembled part in position under the action of elastic force. When the first to-be-assembled part and the second to-be-assembled part need to be loosened, the second driving member drives the third clamping member to withdraw and drives the fourth clamping member to withdraw together. Therefore, the setting of the fourth elastic member can increase the clamping force of the first to-be-assembled part.

[0030] In some embodiments, when the third clamping member and the fourth clamping member are in a clamping state, along the second direction Y, the distance between the end of the second positioning member facing the third clamping member and the fourth movable end is L1, and the distance between the end of the second positioning member facing the third clamping member and the third movable end is L2, wherein L1 is smaller than L2.

[0031] In this way, clamping and positioning of the first component to be assembled and the second component to be assembled when the dimensions along the second direction are different can be achieved.

[0032] In some embodiments, the third pressing member comprises:

[0033] A first movable portion, slidably connected to the base assembly along a second direction;

[0034] A second movable portion is connected to the first movable portion, and the second movable portion is slidably connected to the fourth pressing member along a second direction;

[0035] The abutting portion is located on a side of the second movable portion facing the second positioning member and is connected to the second movable portion. The surface of the abutting portion facing the second positioning member forms a third movable end.

[0036] Thereby, the sliding connection between the third pressing member and the base assembly, and the connection between the third pressing member and the fourth pressing member are facilitated.

[0037] In some embodiments, the surface of the second positioning member facing the second clamping mechanism forms a first positioning surface and a second positioning surface, the first positioning surface is used to limit the movement of the first to-be-assembled part along the second direction, and the second positioning surface is used to limit the movement of the second to-be-assembled part along the second direction. In this way, clamping and positioning can be achieved when the sizes of the first to-be-assembled part and the second to-be-assembled part along the second direction are different.

[0038] In some embodiments, the assembly positioning tool also includes a first auxiliary support member and a second auxiliary support member, which are respectively arranged on the base assembly and spaced apart along the second direction, and are respectively used to support the second part to be assembled.

[0039] When the sizes of the first and second parts to be assembled are relatively large, the first and second auxiliary supporting members may play the role of auxiliary support to reduce deformation of the first and second parts to be assembled during the clamping process.

[0040] In a second aspect, the present application provides a battery production system, including the assembly positioning tool of the first aspect, the first part to be assembled is a battery module, and the second part to be assembled is a water cooling plate.

[0041] Since the battery production system includes all the technical features of the assembly positioning tooling, the effects are the same as those of the assembly positioning tooling and will not be repeated here.

[0068] When assembling the battery module and the water-cooling plate, a positioning tool is required for positioning. The current positioning tool clamps the battery module and the water-cooling plate at the same time through a clamping device. The problem is that the battery module and the water-cooling plate have different lengths and widths, and only one of the battery module and the water-cooling plate will be clamped, which can easily cause large assembly deviations.

[0069] In view of this, the present application provides an assembly positioning tool, in which the first movable end can press the first part to be assembled against the first positioning part alone along the first direction, and the second movable end can press the second part to be assembled against the first positioning part alone along the first direction. The first part to be assembled can be a battery module, and the second part to be assembled can be a water-cooling plate, so that the battery module and the water-cooling plate are both against the first positioning part alone along the first direction, which can reduce the probability that the battery module or the water-cooling plate does not abut against the first positioning part, thereby improving the assembly accuracy of the battery module and the water-cooling plate along the first direction. At the same time, the third movable end can press the battery module against the second positioning part alone along the second direction, and the fourth movable end can press the water-cooling plate against the second positioning part alone along the second direction, so as to reduce the probability that the battery module or the water-cooling plate does not abut against the second positioning part, thereby improving the assembly accuracy of the battery module and the water-cooling plate along the second direction.

[0070] The assembly positioning tool provided in the present application can be used for but not limited to the assembly of batteries.

[0071] For the convenience of explanation, please refer to the following examples. Figure 1-Figure 6 , an assembly positioning tool 100 of some embodiments of the present application is taken as an example for description.

[0072] The assembly and positioning tool 100 includes a base assembly 10, a first clamping assembly 20 and a second clamping assembly 30. The first clamping assembly 20 includes a first clamping mechanism 21 and a first positioning member 22, the first clamping mechanism 21 and the first positioning member 22 are arranged at intervals along the first direction X, the first clamping mechanism 21 has a first movable end 2111 and a second movable end 21231, the first movable end 2111 is used to press the first to-be-assembled part to the first positioning member 22 along the first direction X, and the second movable end 21231 is used to press the second to-be-assembled part to the first positioning member 22 along the first direction X. The second clamping assembly 30 is arranged on the base assembly 10, and the second clamping assembly 30 includes a second clamping mechanism 31 and a second positioning member 32. The second clamping mechanism 31 and the second positioning member 32 are spaced apart along the second direction Y. The second clamping mechanism 31 has a third movable end 31131 and a fourth movable end 3121. The third movable end 31131 is used to press the first part to be assembled to the second positioning member 32 alone along the second direction Y, and the fourth movable end 3121 is used to press the second part to be assembled to the second positioning member 32 alone along the second direction Y. The first direction X is different from the second direction Y.

[0073] Optionally, the base assembly 10 is generally a plate-shaped structure, one side surface of the base assembly 10 forms a mounting surface, the first clamping assembly 20 and the second clamping assembly 30 are mounted on the mounting surface, and the first direction X and the second direction Y are parallel to the mounting surface.

[0074] Optionally, the first movable end 2111, the second movable end 21231, the fourth movable end 3121 and the fourth movable end 3121 can all be moved individually by manual operation, or can all be driven to move by a driving component, so that the first part to be assembled abuts against the first positioning part 22 and the second positioning part 32, and the second part to be assembled abuts against the first positioning part 22 and the second positioning part 32.

[0075] The angle between the first direction X and the second direction Y is greater than 0° and less than 180°. When the assembly positioning tool 100 is used in battery assembly, the first direction X and the second direction Y are substantially perpendicular.

[0076] The first movable end 2111 can press the first part to be assembled onto the first positioning member 22 alone, and the second movable end 21231 can press the second part to be assembled onto the first positioning member 22 alone. The first part to be assembled can be a battery module, and the second part to be assembled can be a water-cooling plate. The battery module and the water-cooling plate are both individually pressed against the first positioning member 22, which can reduce the probability that the battery module or the water-cooling plate does not press against the first positioning member 22, thereby improving the assembly accuracy of the battery module and the water-cooling plate along the first direction X. At the same time, the third movable end 31131 can press the battery module onto the second positioning member 32 alone, and the fourth movable end 3121 is used to press the water-cooling plate onto the second positioning member 32 alone, which can reduce the probability that the battery module or the water-cooling plate does not press against the second positioning member 32, thereby improving the assembly accuracy of the battery module and the water-cooling plate along the second direction Y.

[0077] In some embodiments, please refer to Figure 1 and Figure 2 The first clamping mechanism 21 includes a first clamping member 211 and a second clamping member 212. The first clamping member 211 forms a first movable end 2111 along the first direction X toward one end of the first positioning member 22. The second clamping member 212 is slidably connected to the base assembly 10 along the first direction X. The first clamping member 211 and the second clamping member 212 are slidably connected along the first direction X. The second clamping member 212 forms a second movable end 21231 toward one end of the first positioning member 22.

[0078] Specifically and optionally, the base assembly 10 includes a base 11 and a guide rail 12 , wherein the guide rail 12 and the first connecting member are respectively connected to the base 11 , and the guiding direction of the guide rail 12 is the same as the first direction X. The second pressing member 212 is slidably connected to the guide rail 12 along the first direction X.

[0079] Optionally, the first clamping member 211 can be but is not limited to a rod-shaped structure, and one end of the second clamping member 212 is provided with a through hole, which is a through hole along the first direction X. The first clamping member 211 is arranged with the through hole and can move along the first direction X relative to the through hole.

[0080] During the clamping and positioning process of the first and second parts to be assembled, the first and second parts to be assembled can be manually pushed to move along the first direction X, so that the first and second parts to be assembled are respectively pressed against the first positioning member 22, and the first positioning member 22 positions the first and second parts to be assembled along the first direction X. Therefore, the first pressing member 211 presses the first part to be assembled against the first positioning member 22, and the second pressing member 212 presses the second part to be assembled against the first positioning member 22, so that the assembly accuracy of the first and second parts to be assembled along the first direction X can be improved.

[0081] In some embodiments, please refer to Figure 4 and Figure 5 The first clamping mechanism 21 also includes a first driving component 23 and a first elastic component 24. The second clamping component 212 is elastically connected to the first clamping component 211 through the first elastic component 24. The first driving component 23 is used to drive one of the first clamping component 211 and the second clamping component 212 to move relative to the base assembly 10 along the first direction X, and can enable the first clamping component 211 to move relative to the second clamping component 212 along the first direction X.

[0082] Optionally, the first elastic member 24 may be, but is not limited to, a compression spring or a butterfly spring. Taking the first elastic member 24 as a compression spring as an example, the first pressing member 211 is a rod-shaped structure, and the first elastic member 24 is sleeved on the first pressing member 211 .

[0083] The first driving component 23 includes but is not limited to a cylinder or an electric push rod.

[0084] The second pressing piece 212 is elastically connected to the first pressing piece 211, and the first driving component 23 drives the first pressing piece 211 to move, so as to press the first part to be assembled against the first positioning component 22, and at the same time, the second pressing piece 212 moves under the elastic force of the first elastic component 24, so as to press the second part to be assembled against the first positioning component 22, or the first driving component 23 drives the second pressing piece 212 to move, so as to press the second pressing piece 212 against the second part to be assembled, and at the same time, the first pressing piece 211 moves under the elastic force of the first elastic component 24, so as to press the first part to be assembled against the first positioning component 22, thereby realizing the separate clamping and positioning of the first part to be assembled and the second part to be assembled (the first part to be assembled is clamped and positioned by the first pressing piece 211, and the second part to be assembled is clamped and positioned by the second pressing piece 212), so as to improve the assembly accuracy of the first part to be assembled and the second part to be assembled; at the same time, compared with the manual operation method, it saves more manpower and can maintain the positioning state of the first part to be assembled and the second part to be assembled.

[0085] In some embodiments, see Figure 4The first clamping member 211 is inserted into the second clamping member 212 and is drivingly connected to the first driving member 23. The first elastic member 24 is located on the side of the second clamping member 212 away from the first positioning member 22. One end of the first elastic member 24 abuts against the second clamping member 212, and the other end of the first elastic member 24 abuts against the first clamping member 211.

[0086] Optionally, the first clamping member 211 forms limiting structures at both ends along the first direction X, wherein one limiting structure abuts against the first elastic member 24 and the other limiting structure is configured to abut against the second clamping member 212 to limit the moving distance of the first clamping member 211 .

[0087] When the first driving component 23 drives the first clamping member 211 to move and press the first part to be assembled against the first positioning member 22, the first elastic member 24 is compressed, and under the action of the elastic force, drives the second clamping member 212 to press the second part to be assembled against the first positioning member 22, so that the first clamping member 211 presses the first part to be assembled against the first positioning member 22 alone along the first direction X, and the second clamping member 212 presses the second part to be assembled against the second positioning member 32 alone along the second direction Y, so that the first part to be assembled and the second part to be assembled can both abut against the first positioning member 22 along the first direction X, thereby improving the assembly accuracy of the first part to be assembled and the second part to be assembled along the first direction X.

[0088] In some embodiments, please refer to Figure 5 Along the first direction X, one end of the first elastic member 24 abuts against the surface of the second pressing member 212 facing the first positioning member 22, the other end of the first elastic member 24 abuts against the first pressing member 211, and the first driving member 23 is drivingly connected to the second pressing member 212.

[0089] When the first driving component 23 drives the second clamping member 212 to move and press the second part to be assembled against the first positioning member 22, the first elastic member 24 is compressed, and under the action of the elastic force, the first clamping member 211 is driven to press the first part to be assembled against the first positioning member 22, so as to realize the separate clamping of the first part to be assembled by the first clamping member 211 and the separate clamping of the second part to be assembled by the second clamping member 212, so that the first part to be assembled and the second part to be assembled can both abut against the first positioning member 22, thereby improving the assembly accuracy of the first part to be assembled and the second part to be assembled along the first direction X.

[0090] In some embodiments, please refer to Figure 2The first clamping mechanism 21 also includes a second elastic member 60, which is located on the side of the second clamping member 212 facing the positioning member, one end of the second elastic member 60 abuts against the second clamping member 212, and the other end of the second elastic member 60 abuts against the base assembly 10, and the stiffness of the second elastic member 60 is less than the stiffness of the first elastic member 24. When the first clamping member 211 and the second clamping member 212 are in a clamped state, the first elastic member 24 and the second elastic member 60 are both in a compressed state.

[0091] Optionally, the second elastic member 60 may be, but is not limited to, a compression spring or an elastic disc.

[0092] Exemplarily, the base assembly 10 further includes a first stopper 13 , which is located along the first direction X on a side of the second pressing member 212 facing the first positioning member 22 , and both ends of the second elastic member 60 abut against the first stopper 13 and the second pressing member 212 .

[0093] When the first to-be-assembled component and the second to-be-assembled component are clamped and positioned, the elastic force of the first elastic member 24 is smaller than the elastic force of the second elastic member 60 .

[0094] The driving end of the first driving component 23 can be abutted against or spaced from the first pressing member 211 or the second pressing member 212. When the driving end of the first driving component 23 moves in the direction opposite to the clamping direction, the first pressing member 211 and the second pressing member 212 release the first and second parts to be assembled under the elastic force of the second elastic member 60, so as to facilitate the removal of the first and second parts to be assembled and to be assembled and used next time. The rigidity of the first elastic member 24 is greater than that of the second elastic member 60, so that the first and second parts to be assembled can be clamped under the elastic force difference between the first elastic member 24 and the second elastic member 60, so that the first and second parts to be assembled can be clamped and positioned separately.

[0095] In some embodiments, please refer to Figure 2 The second pressing member 212 includes a first connecting portion 2121, a second connecting portion 2122 and a pressing portion 2123. The first connecting portion 2121 is slidably connected to the base assembly 10 along the first direction X. The second connecting portion 2122 is connected to the first connecting portion 2121 and is slidably connected to the first pressing member 211 along the first direction X. The second connecting portion 2122 is elastically connected to the first pressing member 211 through the first elastic member 24. The pressing portion 2123 is connected to the first connecting portion 2121, and the pressing portion 2123 forms a second movable end 21231 toward one end of the first positioning member 22.

[0096] The connection between the second connection part 2122 and the first connection part 2121, and the connection between the pressing part 2123 and the first connection part 2121 or the second connection part 2122 include but are not limited to screw connection, welding or riveting, etc. Specifically, the first connection part 2121 can be slidably connected to the guide rail 12 of the base assembly 10 through a slider.

[0097] Thus, the movable connection between the second pressing member 212 and the first pressing member 211 and the sliding connection between the second pressing member 212 and the base assembly 10 are facilitated.

[0098] In some embodiments, please refer to Figure 3 and Figure 6 The second clamping mechanism 31 includes a third clamping member 311 and a fourth clamping member 312. The fourth clamping member 312 is slidably connected to the base assembly 10 along the second direction Y. The fourth clamping member 312 is slidably connected to the third clamping member 311 along the second direction Y. The fourth clamping member 312 forms a fourth movable end 3121 toward one end of the second positioning member 32.

[0099] Optionally, the base assembly 10 further includes a first connection block 14, a second connection block 15 and a guide rod 16. The first connection block 14 and the second connection block 15 are spaced apart from each other on the base 11 along the second direction Y, and the guide rod 16 is connected between the first connection block 14 and the second connection block 15, and the axis of the guide rod 16 is the same as the second direction Y. The fourth pressing member 312 is slidably connected to the guide rod 16.

[0100] Optionally, the fourth pressing member 312 is slidably connected to the third pressing member 311 via a guide shaft.

[0101] During the clamping and positioning process of the first and second parts to be assembled, the third pressing member 311 and the fourth pressing member 312 can be manually pushed to move along the first direction X, so that the first and second parts to be assembled are respectively pressed against the second positioning member 32, and the third positioning member positions the first and second parts to be assembled along the second direction Y. Therefore, the third pressing member 311 presses the first part to be assembled against the second positioning member 32, and the fourth pressing member 312 presses the second part to be assembled against the second positioning member 32, which can improve the assembly accuracy of the first and second parts to be assembled along the second direction Y.

[0102] In some embodiments, please refer to Figure 3 and Figure 6The second clamping mechanism 31 also includes a third elastic member 313 and a fourth elastic member 70. One end of the third elastic member 313 abuts against the surface of the third clamping member 311 facing the second positioning member 32, and the other end of the third elastic member 313 abuts against the fourth clamping member 312. The fourth elastic member 70 is located on the side of the third clamping member 311 away from the second positioning member 32. One end of the fourth elastic member 70 abuts against the base assembly 10, and the other end of the fourth elastic member 70 abuts against the third clamping member 311.

[0103] The third elastic member 313 and the fourth elastic member 70 may be, but are not limited to, compression springs or elastic discs.

[0104] The arrangement of the third elastic member 313 and the fourth elastic member 70 enables the third clamping member 311 and the fourth clamping member 312 to separately clamp the first and second parts to be assembled onto the second positioning member 32 under elastic action, so as to keep the first and second parts to be assembled in a positioned state for easy assembly.

[0105] In some embodiments, the second pressing mechanism 31 further includes a second driving component 314 , which is drivingly connected to the third pressing member 311 and is used to drive the third pressing member 311 to move along the second direction Y.

[0106] Optionally, the second driving component 314 includes but is not limited to an electric push rod or a cylinder.

[0107] Thus, the second driving component 314 can drive the third clamping component 311. The second driving component 314 overcomes the elastic force of the first elastic component 24 and the second elastic component 60, and can pull back the third clamping component 311 and the fourth clamping component 312 to loosen the first assembly and the second assembly to facilitate the next assembly positioning. At the same time, compared with the manual pulling back method, it saves more manpower.

[0108] In some embodiments, please refer to Figure 3 When the third clamping member 311 and the fourth clamping member 312 are in a clamping state, along the second direction Y, the distance between the end of the second positioning member 32 facing the third clamping member 311 and the fourth movable end 3121 is L1, and the distance between the end of the second positioning member 32 facing the third clamping member 311 and the third movable end 31131 is L2, wherein L1 is smaller than L2.

[0109] In this way, the clamping and positioning of the first component to be assembled and the second component to be assembled when the dimensions along the second direction Y are different can be achieved.

[0110] In some embodiments, please refer to Figure 6The third pressing member 311 includes a first movable portion 3111, a second movable portion 3112 and an abutting portion 3113. The first movable portion 3111 is slidably connected to the base assembly 10 along the second direction Y. The second movable portion 3112 is connected to the first movable portion 3111, and the second movable portion 3112 is slidably connected to the fourth pressing member 312 along the second direction Y. The abutting portion 3113 is located on a side of the second movable portion 3112 facing the second positioning member 32, and is connected to the second movable portion 3112. The surface of the abutting portion 3113 facing the second positioning member 32 forms a third movable end 31131.

[0111] The connection between the second movable portion 3112 and the first movable portion 3111 and the connection between the abutting portion 3113 and the second movable portion 3112 include, but are not limited to, integral molding connection, welding or screw connection.

[0112] Thus, the sliding connection between the third pressing member 311 and the base assembly 10 and the connection between the third pressing member 311 and the fourth pressing member 312 are facilitated.

[0113] In some embodiments, please refer to Figure 3 The surface of the second positioning member 32 facing the second clamping mechanism 31 forms a first positioning surface 321 and a second positioning surface 322, the first positioning surface 321 is used to limit the movement of the first to-be-assembled component along the second direction Y, and the second positioning surface 322 is used to limit the movement of the second to-be-assembled component along the second direction Y.

[0114] The first positioning surface 321 and the second positioning surface 322 may be coplanar or non-coplanar, which may be determined according to the dimensions of the first to-be-assembled component and the second to-be-assembled component along the second direction Y.

[0115] In this way, the clamping and positioning of the first component to be assembled and the second component to be assembled when the dimensions along the second direction Y are different can be achieved.

The first auxiliary support member 40 and the second auxiliary support member 50 are respectively used to support the second part to be assembled.

[0117] When the sizes of the first and second parts to be assembled are relatively large, the first and second auxiliary supports 40 and 50 can play the role of auxiliary support to reduce deformation of the first and second parts to be assembled during the clamping process.

[0118] For the convenience of description, the following embodiments are described by taking a battery production system according to some embodiments of the present application as an example.

[0121] During the assembly process, the water-cooling plate can be placed at a predetermined position of the assembly positioning tool 100 first, and then the battery module can be placed on the water-cooling plate. The battery module and the water-cooling plate can be clamped and positioned by the first clamping member 211, the second clamping member 212, the third clamping member 311 and the fourth clamping member 312 to limit the position of the battery module and the water-cooling plate along the first direction X and the second direction Y.
