[0023] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0024] The tooling 10 for assembling a battery module according to an embodiment of the present invention will be described below with reference to the accompanying drawings. As Figures 1 - 6 shown, the tooling 10 for assembling a battery module according to an embodiment of the present invention includes a bottom plate 110, a first end plate 121, a second end plate 122, and a plurality of clamping plates 130.

[0025] The first end plate 121 and the second end plate 122 can be arranged on the bottom plate 110 at intervals along the length direction of the bottom plate 110, and at least one of the first end plate 121 and the second end plate 122 can be detachably arranged on the bottom plate 110.

[0026] Each pallet 130 can be detachably disposed on the bottom plate 110, and a plurality of pallets 130 can be arranged between the first end plate 121 and the second end plate 122 along the length direction of the bottom plate 110. Wherein, a slot 131 for accommodating the battery 20 can be defined between two adjacent pallets 130, and at least one of the first end and the second end of the slot 131 opposite to each other in the width direction of the bottom plate 110 can be open, and the third end of the slot 131 away from the bottom plate 110 in the height direction of the bottom plate 110 can be open.

[0027] To make the technical solution of the present application easier to understand, the left-right direction (as shown by arrow A), the up-down direction (as shown by arrow B), and the front-back direction (as shown by arrow C) are marked in Figure 4 as shown.

[0028] The first end plate 121 and the second end plate 122 can be disposed on the bottom plate 110 at intervals in the left-right direction, and a plurality of pallets 130 can be arranged between the first end plate 121 and the second end plate 122 along the left-right direction. At least one of the front end and the rear end of the slot 131 can be open, and the upper end of the slot 131 can be open. Wherein, when the positive electrodes or negative electrodes of a plurality of batteries 20 are on the same side, the plurality of slots 131 cooperating with the plurality of batteries 20 are open in the same direction, and when the positive electrodes or negative electrodes of two adjacent batteries 20 are on opposite sides, the two slots 131 cooperating with the two adjacent batteries 20 are open towards each other. That is to say, when the positive electrode tab and the negative electrode tab of the battery 20 are on the same side of the battery 20, one of the front end and the rear end of the slot 131 can be open; when the positive electrode tab and the negative electrode tab of the battery 20 are on opposite sides of the battery 20, both the front end and the rear end of the slot 131 can be open.

[0029] Next, refer to Figures 1 - 6 to briefly describe the process of assembling the battery module by using the tooling 10 for assembling the battery module according to the embodiment of the present invention.

[0030] First, a plurality of pallets 130 are installed on the bottom plate 110 to form a plurality of slots 131, and a plurality of batteries 20 are respectively loaded into the plurality of slots 131 one by one, that is, one battery 20 is installed in one slot 131 (as Figures 1 - 3 shown). Thus, the process of stacking the batteries 20 can be completed. Wherein, the battery 20 can be loaded into the slot 131 from top to bottom, and the battery 20 can also be loaded into the slot 131 from front to back or from back to front.

[0031] Then, the plurality of pallets 130 are compacted to compact the plurality of batteries 20. Then, the insulating brackets 30 and the series connection rows 40 are sequentially installed on the positive electrode tabs and negative electrode tabs of the plurality of batteries 20, and the positive electrode tabs and negative electrode tabs of the batteries 20 are first bent and then welded to the corresponding series connection rows 40 by using welding equipment (as Figure 5 shown).

[0032] Finally, the PCB board 50 is installed on the tab surfaces of the plurality of batteries 20, and the voltage sampling copper sheet 51 of the PCB board 50 is welded to the series row 40 (as Figure 6 shown). Remove the tooling 10 to obtain the battery module.

[0033] The tooling 10 for assembling a battery module according to an embodiment of the present invention can complete a set of processes such as stacking batteries, compaction, tab welding, and PCB board welding by detachably arranging a plurality of clamping plates 130 on the bottom plate 110.

[0034] Therefore, the tooling 10 for assembling a battery module according to an embodiment of the present invention has the advantages of simple structure and simplified battery module assembly processes, and can complete a set of processes such as stacking batteries, compaction, tab welding, and PCB board welding.

[0035] The method for assembling a battery module by using the tooling 10 for assembling a battery module according to an embodiment of the present invention has the advantages of using fewer tools and simple processes.

[0036] As Figures 1 - 6 shown, in some embodiments of the present invention, the tooling 10 for assembling a battery module may include a bottom plate 110, a first end plate 121, a second end plate 122, and a plurality of clamping plates 130. Each clamping plate 130 may include a base 132, a boss 133, a first clamping post 134, and a second clamping post 135. The base 132 may have a first surface 136. Specifically, the first surface 136 may be the upper surface of the base 132. The boss 133 may be provided on the first surface 136 of the base 132.

[0037] The first clamping post 134 and the second clamping post 135 may be provided on the first surface 136 of the boss 133 at intervals along the length direction of the base 132. When the clamping plate 130 is installed on the bottom plate 110, the length direction of the base 132 may be consistent with the width direction of the bottom plate 110.

[0038] Wherein, a card slot 131 is defined between the base 132, the boss 133, the first clamping post 134, and the second clamping post 135 of one of the adjacent two clamping plates 130 and the boss 133, the first clamping post 134, and the second clamping post 135 of the other of the adjacent two clamping plates 130. In other words, the battery 20 is clamped between the base 132, the boss 133, the first clamping post 134, and the second clamping post 135 of one of the adjacent two clamping plates 130 and the boss 133, the first clamping post 134, and the second clamping post 135 of the other of the adjacent two clamping plates 130.

[0039] Specifically, the battery 20 is supported on the base 132 of one of the two adjacent clamping plates 130. The boss 133, the first clamping post 134, and the second clamping post 135 of this one clamping plate 130 can be located on one of the left and right sides of the battery 20, and the boss 133, the first clamping post 134, and the second clamping post 135 of the other clamping plate 130 can be located on the other of the left and right sides of the battery 20.

[0040] Preferably, the base 132, the boss 133, the first clamping post 134, and the second clamping post 135 can be integrally formed, that is, the clamping plate 130 can be a single-piece. This can not only improve the structural strength of the clamping plate 130, but also reduce the manufacturing difficulty and cost of the clamping plate 130.

[0041] As Figure 3 shown, the first clamping posts 134 of multiple clamping plates 130 can be opposite to each other in the length direction of the bottom plate 110, and the second clamping posts 135 of multiple clamping plates 130 can be opposite to each other in the length direction of the bottom plate 110. That is to say, after multiple clamping plates 130 are installed on the bottom plate 110, the first clamping posts 134 of multiple clamping plates 130 can be opposite to each other in the length direction of the bottom plate 110, and the second clamping posts 135 of multiple clamping plates 130 can be opposite to each other in the length direction of the bottom plate 110. This can make the structure of the tooling 10 more reasonable.

[0042] The dimensions of each of the boss 133, the first clamping post 134, and the second clamping post 135 of each clamping plate 130 in the width direction of the base 132 can be equal to each other. In other words, the dimension of the boss 133 in the width direction of the base 132 can be equal to the dimension of the first clamping post 134 in the width direction of the base 132, and the dimension of the boss 133 in the width direction of the base 132 can be equal to the dimension of the second clamping post 135 in the width direction of the base 132. When the clamping plate 130 is installed on the bottom plate 110, the width direction of the base 132 can be consistent with the length direction of the bottom plate 110.

[0043] The boss 133 of each clamping plate 130 can have opposite second and third surfaces in the width direction of the base 132, and each of the first clamping post 134 and the second clamping post 135 of each clamping plate 130 can have opposite second and third surfaces in the width direction of the base 132. Among them, the second surface of the boss 133 and the second surface of each of the first clamping post 134 and the second clamping post 135 can be located on the same plane, and the third surface of the boss 133 and the third surface of each of the first clamping post 134 and the second clamping post 135 can be located on the same plane. This can make the structure of the clamping plate 130 and the tooling 10 more reasonable.

[0044] When the card board 130 is installed on the bottom board 110, that is, when the tooling 10 is in use, the second surface of the boss 133 and the second surface of each of the first clamping post 134 and the second clamping post 135 can be located on the same vertical plane, and the third surface of the boss 133 and the third surface of each of the first clamping post 134 and the second clamping post 135 can be located on the same vertical plane.

[0045] Multiple card boards 130 can form multiple card board groups, and each such card board group can include 1 - 8 card boards 130. Preferably, each such card board group can include 2 - 5 card boards 130. Each card board 130 of one of the two adjacent card board groups can be arranged back to back with each card board 130 of the other of the two adjacent card board groups. Thus, the battery stacking process can be better completed.

[0046] For example, the boss 133 of each card board 130 of one of the two adjacent card board groups can be located on the right side of the part of the first surface 136 where no boss 133 is provided, and the boss 133 of each card board 130 of the other of the two adjacent card board groups can be located on the left side of the part of the first surface 136 where no boss 133 is provided.

[0047] Preferably, the dimension of each of the first clamping post 134 and the second clamping post 135 of one card board 130 in the width direction of the base 132 is smaller than the dimension of its boss 133 in the width direction of the base 132. When multiple card boards 130 are installed on the bottom board 110, that is, when the tooling 10 is in use, this one card board 130 is adjacent to another card board group. Thus, in the battery stacking process, it is more convenient and easier to set a heat conducting member between two adjacent card board groups (i.e., two adjacent battery modules). Among them, a battery module includes multiple batteries 20 connected in parallel.

[0048] More preferably, one of the second surface and the third surface of the boss 133 and the corresponding one of the second surface and the third surface of the first clamping post 134 can be located on the same plane, and one of the second surface and the third surface of the boss 133 and the corresponding one of the second surface and the third surface of the second clamping post 135 can be located on the same plane. Thus, the structure of the tooling 10 can be made more reasonable, and the battery stacking process can be better completed.

[0049] As Figures 3 - 6 shown, in an embodiment of the present invention, one of a clamping groove 137 and a clamping projection 111 can be provided on the bottom board 110, and the other of the clamping groove 137 and the clamping projection 111 can be provided on the base 132, and the clamping projection 111 is fitted in the clamping groove 137. Thus, the card board 130 can be conveniently and detachably arranged on the bottom board 110.

[0050] Specifically, a clamping protrusion 111 may be provided on the upper surface of the bottom plate 110, and the clamping protrusion 111 and the bottom plate 110 may be integrally formed. The clamping protrusion 111 may extend along the length direction (e.g., left-right direction) of the bottom plate 110. A clamping groove 137 may be provided on the base 132, and each of the lower end, left end, and right end of the clamping groove 137 may be open. Thus, by assembling the clamping plate 130 onto the clamping protrusion 111 and moving the clamping plate 130 in the left-right direction, a plurality of clamping plates 130 may be arranged between the first end plate 121 and the second end plate 122 along the length direction of the bottom plate 110.

[0051] Preferably, the engaging groove 137 may be a dovetail groove, and the shape of the engaging protrusion 111 may be adapted to the shape of the dovetail groove. Thus, the clamping plate 130 can be more firmly mounted on the bottom plate 110, and the clamping plate 130 will not be separated from the bottom plate 110 when the tooling 10 is turned upside down (vertically turned).

[0052] The first end plate 121 can be mounted on the first side surface (left side surface) of the bottom plate 110 by means of fasteners (such as screws or bolts). Figures 3 - 6 As shown, the second end plate 122 may be provided with a snap-fitting groove, and each of the lower end, the left end and the right end of the snap-fitting groove may be open. Thus, the second end plate 122 may be detachably mounted on the bottom plate 110 by assembling the second end plate 122 onto the snap-fitting protrusion 111 .

[0053] Preferably, a slot 131 can be defined between the first end plate 121 and the adjacent clamping plate 130, and a slot 131 can be defined between the second end plate 122 and the adjacent clamping plate 130. This can make the structure of the tool 10 more reasonable.

[0054] like Figures 3 - 6 As shown, one of the first end plate 121 and the second end plate 122 may be provided with a positive electrode avoidance hole, and the other of the first end plate 121 and the second end plate 122 may be provided with a negative electrode avoidance hole. This can make the structure of the tooling 10 more reasonable.

[0055] In some examples of the present invention, the tool 10 may further include a pressing member, which can cooperate with at least one of the first end plate 121 and the second end plate 122 to press the plurality of clamping plates 130 through the at least one of the first end plate 121 and the second end plate 122. This can better complete the compaction process.

[0056] Preferably, each of the first end plate 121 and the second end plate 122 can be detachably provided on the bottom plate 110, and the pressing member can cooperate with each of the first end plate 121 and the second end plate 122 to apply a first pressing force to the first end plate 121 toward the second end plate 122 and a second pressing force to the second end plate 122 toward the first end plate 121. Thus, the compaction process can be better completed.

[0057] As Figures 3 - 6 shown, in an example of the present invention, the pressing member may include a screw 141, a first clamping member 142, and a second clamping member (not shown in the figure). The screw 141 can pass through each of the first end plate 121, the second end plate 122, and the plurality of card plates 130 along the length direction of the bottom plate 110.

[0058] Specifically, through holes may be provided on each of the first end plate 121 and the second end plate 122, and through holes may be provided on the base 132 of each card plate 130. The screw 141 can pass through the through holes of the first end plate 121, the through holes of the second end plate 122, and the through holes of the base 132 of each card plate 130.

[0059] The first clamping member 142 and the second clamping member can be provided on the screw 141, and at least one of the first clamping member 142 and the second clamping member can be sleeved on the screw 141 through a thread. Among them, the first clamping member 142 can abut against the first end plate 121, and the second clamping member can abut against the second end plate 122. Thus, a plurality of batteries 20 can be more conveniently and easily compacted, and thus the process of stacking batteries can be more easily and better completed. Preferably, the first clamping member 142 may be a nut, and the second clamping member may also be a nut.

[0060] As Figures 4 - 6 shown, the tooling 10 may further include a top plate 151, and the top plate 151 can be detachably provided on at least one of the first end plate 121 and the second end plate 122. Thus, when the tooling 10 is turned upside down for removing the tooling 10, the top plate 151 can be used to protect a plurality of batteries 20.

[0061] Preferably, as Figures 4 - 6 shown, there may be a plurality of top plates 151, and the plurality of top plates 151 may be arranged at intervals along the width direction of the bottom plate 110. Among them, each top plate 151 can be connected to the first end plate 121 through a first buckle 161, and each top plate 151 can be connected to the second end plate 122 through a second buckle 162.

[0062] In a specific example of the present invention, the tooling 10 for assembling the battery module may further include a first side plate and a second side plate. The first side plate can be detachably disposed on at least one of the bottom plate 110, the first end plate 121, and the second end plate 122, and the second side plate can be detachably disposed on at least one of the bottom plate 110, the first end plate 121, and the second end plate 122. Wherein, the first side plate and the second side plate can be arranged at intervals along the width direction of the bottom plate 110, and a plurality of clamping plates 130 can be located between the first side plate and the second side plate along the width direction of the bottom plate 110. Thus, the first side plate and the second side plate can be used to protect the plurality of batteries 20.

[0063] When welding the tabs of the plurality of batteries 20 and welding the PCB board, the tabs and the PCB board to be welded can face upward. By providing the first side plate and the second side plate, when welding the tabs and the PCB board on one side (e.g., one of the front side and the rear side) of the plurality of batteries 10, the first side plate and the second side plate can be used to protect the other side (e.g., the other of the front side and the rear side) of the plurality of batteries 20.

[0064] As Figure 1 and Figure 2 shown, in another specific example of the present invention, each base 132 of each clamping plate 130 has a first end face (not shown in the figure) and a second end face 1321 in its length direction. Wherein, each of the first clamping post 134 and the second clamping post 135 is located between the first end face and the second end face 1321 in the length direction of the base 132.

[0065] Specifically, for example, the first clamping post 134 can be located in front of the second clamping post 135, the first end face can be located in front of the first clamping post 134, and the second end face 1321 can be located behind the second clamping post 135.
