[0063] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0064] This embodiment relates to a busbar fixing tooling. In terms of the overall structure, as Figure 1 shown, the busbar fixing tooling includes: a module tray 1 and a tooling body 3.

[0065] Among them, the module tray 1 is used to support the battery cell module 2. The battery cell module 2 is composed of a plurality of battery cells arranged along the length direction of the module tray 1, so that the pole columns of the battery cells are located on one side surface or two opposite side surfaces of the battery cell module 2. The tooling body 3 is disposed on two opposite sides of the battery cell module 2. The tooling body 3 is provided with a plurality of positioning pins 4 extending towards the battery cell module 2, and the busbar 5 is provided with a plurality of positioning holes 502 corresponding to the positioning pins 4 one by one, as Figure 10 、 Figure 11 、 Figure 12 and Figure 13 shown. Each positioning pin 4 can pass through each positioning hole 502 to mount the busbar 5 on the tooling body 3.

[0066] At the same time, the module tray 1 is provided with an installation mechanism. Each tooling body 3 is detachably connected to the module tray 1 through the installation mechanism, so that each tooling body 3 is vertically fixed on both sides of the battery cell module 2. When the tooling body 3 mounted with the busbar 5 is connected to the module tray 1, the busbar 5 is fixed by the tooling body 3 on the side of the battery cell module 2 where the pole columns are provided.

[0067] As described above, through the arrangement of the positioning pins 4 on the module tray 1 and the tooling body 3, the busbar 5 of this embodiment can be mounted on the tooling body 3 through the cooperation of the positioning holes 502 and the positioning pins 4. After connecting the tooling body 3 to the module tray 1, the busbar 5 can be fixed on the side of the battery cell module 2 where the pole columns are provided to realize the fixation of the busbar 5 and the battery cell module 2, thus facilitating the subsequent connection operation between the busbar 5 and the battery cell module 2.

[0068] Based on the above overall introduction, specifically, as Figure 3 、 Figure 4 and Figure 5 shown, this embodiment is provided with two tooling bodies 3 for mounting the busbar 5. When the pole columns on the battery cell module 2 are respectively disposed on two opposite side surfaces of the battery cell module 2, the two tooling bodies 3 of this embodiment can simultaneously fix the two busbars 5 on both sides of the battery cell module 2 where the pole columns are provided, improving the installation efficiency of the busbar 5. At the same time, since a plurality of tabs 503 for connecting the battery cell pole columns are provided in the middle of the busbar 5, in order to facilitate mounting the busbar 5 on the tooling body 3, each positioning hole 502 is provided at the upper end of the busbar bracket 501 of the busbar 5.

[0069] In order to improve the fixing effect of the busbar 5 to facilitate the subsequent connection operation between the busbar 5 and the battery cell module 2, as Figure 7 andFigure 8 As shown in the figure, the tooling body 3 of this embodiment includes two side plates 301 arranged at intervals along the length direction of the module tray 1, a top cross beam 302 and a bottom cross beam 303 connected between the two side plates 301. An upper limit plate 304 is provided on the top cross beam 302, and a lower limit plate 305 is provided on the bottom cross beam 303. Each positioning pin 4 is arranged on the upper limit plate 304. With such a setting, by arranging each positioning pin 4 on the upper limit plate 304, after the busbar 5 is mounted on the tooling body 3, the upper limit plate 304 and the lower limit plate 305 can press the upper and lower ends of the busbar 5, so as to make the tab 503 closely adhere to each pole column on the side of the battery cell module 2, thereby improving the fixing effect of the busbar 5 and facilitating subsequent connection operations.

[0070] In addition, the upper limit plate 304 and the lower limit plate 305 of this embodiment are both made of non-metallic materials with good insulation performance, and their weights are relatively light, which is convenient for the disassembly and assembly of the tooling body 3 on the module tray 1. And when the upper limit plate 304 and the lower limit plate 305 press the busbar 5, the upper limit plate 304 and the lower limit plate 305 can abut against the upper and lower ends of each tab 503. While pressing the tab 503, it can prevent short circuits between the battery cells. At the same time, the setting of the top cross beam 302 and the bottom cross beam 303 makes a certain distance left between the upper limit plate 304 and the lower limit plate 305, so that during the subsequent connection operation of the busbar 5 and the battery cell module 2, the operator can weld each tab 503 to the corresponding pole column through this distance, which further facilitates the subsequent connection operation.

[0071] During specific implementation, as Figure 8 shown in the figure, the upper limit plate 304 and the lower limit plate 305 of this embodiment are both connected to the upper limit plate 304 and the lower limit plate 305 by bolts, so as to facilitate the replacement of the upper limit plate 304 and the lower limit plate 305 with different lengths according to the specifications of the battery cell module 2. And installation grooves are respectively provided at the upper and lower ends of each side plate 301, and the top cross beam 302 and the bottom cross beam 303 can be respectively embedded into the installation grooves at the upper and lower ends of the side plate 301 to ensure the connection strength between the side plate 301 and the top cross beam 302 and the bottom cross beam 303. At the same time, the side plate 301 is connected to the top cross beam 302 and the bottom cross beam 303 by bolts, which is convenient for disassembly, installation and maintenance.

[0072] In addition, the upper limit plate 304 and the lower limit plate 305 of this embodiment are set to have a structure matching that of the battery cell module 2. Taking this embodiment as an example, the battery cell module 2 of this embodiment is set to two spaced parts according to actual needs. Therefore, the upper limit plate 304 and the lower limit plate 305 of this embodiment are configured as two separate parts to facilitate connection with the two parts of the battery cell module 2. Similarly, the upper limit plate 304 and the lower limit plate 305 of this embodiment can be configured into different structural shapes or multiple separate structures according to the specific structure of the battery cell module 2, as long as they can mount the busbar 5 and enable the upper limit plate 304 and the lower limit plate 305 to tightly press and fix the busbar 5.

[0073] It can be understood that due to the long length of the tooling body 3, during long-term use, the top cross beam 302 and the bottom cross beam 303 are prone to downward bending in the middle due to their own weight and the weight of the busbar 5, resulting in deformation of the tooling body 3, and further causing deviation in the fixed position of the busbar 5 from the battery cell module 2, resulting in deviation in the installation of the busbar 5.

[0074] Therefore, in order to improve the structural strength of the tooling body 3 and prevent the tooling body 3 from deforming, a connecting plate 306 is provided between the top cross beam 302 and the bottom cross beam 303 of this embodiment. Through the setting of the connecting plate 306, support can be formed between the top cross beam 302 and the bottom cross beam 303 in the height direction, improving the structural strength of the tooling body 3 and thus avoiding deformation of the tooling body 3. At the same time, a backing plate 307 is provided at the bottom of the bottom cross beam 303 of this embodiment, and a cushion block 104 for supporting the backing plate 307 is provided on the module tray 1. The module tray 1 can thus support the backing plate 307 of the bottom cross beam 303 through the cushion block 104, thereby supporting the bottom cross beam 303 in the height direction to prevent the bottom cross beam 303 from bending downward and causing deformation of the tooling body 3. In specific implementation, the connecting plates 306 of this embodiment are set to be multiple and arranged at intervals along the length direction of the tooling body 3. Specifically, the connecting plates 306 of this embodiment are configured as 3, which can improve the structural strength of the tooling body 3 while not significantly increasing the weight of the tooling body 3.

[0075] In order to prevent interference between the upper limit plate 304 and the lower limit plate 305 and the rivets 504 on the busbar support 501 and the nickel sheets on the busbar 5 during the process of the upper limit plate 304 and the lower limit plate 305 pressing the busbar 5, as Figure 10 and Figure 11As shown in the figure, the upper limit plate 304 of this embodiment is provided with a plurality of first avoidance grooves 3041 for avoiding the rivets 504 of the bus bar 5, and the lower limit plate 305 is provided with a plurality of second avoidance grooves 3051 for avoiding the nickel sheets of the bus bar 5. Through the arrangement of each avoidance groove, interference between part of the structure of the tooling body 3 and the bus bar 5 can be avoided.

[0076] In this embodiment, the upper limit plate 304 is provided with a plurality of through holes 3042 for passing through each positioning pin 4, and a flange 401 is formed at one end of the positioning pin 4. The positioning pin 4 can be inserted into the through hole 3042 in the direction towards the battery cell module 2, so that the flange 401 abuts against the side of the upper limit plate 304 away from the battery cell module 2. And the other end of the positioning pin 4 passes through the through hole 3042 and extends to the side of the upper limit plate 304 towards the battery cell module 2. It can be understood that in order to fix bus bars 5 of different specifications, the lengths of the ends of the positioning pins 4 extending towards the battery module are also different. Through the cooperative arrangement of the through holes 3042 and the positioning pins 4, the positioning pins 4 can be detachably fixed on the upper limit plate 304, and at the same time, the flange 401 plays a limiting role, so as to facilitate the replacement of positioning pins 4 of different specifications, so that the tooling body 3 can be compatible with bus bars 5 of different specifications.

[0077] In specific implementation, the through holes 3042 of this embodiment are arranged horizontally and at intervals along the length direction of the upper limit plate 304. The positioning pins 4 are in interference fit with the through holes 3042 to prevent the positioning pins 4 from falling off. The length of the end of the positioning pin 4 extending towards the battery cell module 2 is 3 mm. By replacing the positioning pins 4 of different specifications, the length of the end of the positioning pin 4 extending out can be changed to adapt to bus bars 5 of different specifications.

[0078] After the bus bar 5 is mounted on the tooling body 3, the operator needs to move the tooling body 3 and erect the bus bar 5 and connect it to the module tray 1 through the installation mechanism. During the process of moving the tooling body 3, the bus bar 5 is likely to slide off the positioning pin 4. Therefore, in order to improve the stability of mounting the bus bar 5, the positioning pin 4 of this embodiment is provided with a groove 402 surrounding the positioning pin 4 along the circumference, and the groove 402 is located at one end of the positioning pin 4 close to the battery cell module 2. When the bus bar 5 is mounted on the tooling body 3, the edge of the positioning hole 502 can be caught in the groove 402 to prevent the bus bar 5 from sliding off the positioning pin 4, thereby improving the stability of the tooling body 3 in mounting the bus bar 5.

[0079] In this embodiment, as Figure 2 and Figure 6As shown in the figure, the mounting mechanism includes two pairs of oppositely arranged mounting seats 6. Each mounting seat 6 corresponds to each side plate 301 one by one. That is, any tooling body 3 is fixed on the module tray 1 through two mounting seats 6. Among them, the mounting seat 6 includes a support block 601 and a fixing plate 602 vertically arranged on the support block 601. The side plate 301 can be placed on the top of the support block 601, and the side of the side plate 301 facing the battery module 2 abuts against the fixing plate 602. And the side plate 301 can be detachably fixed on the mounting seat 6 through a connecting part. Through the arrangement of the support block 601 and the fixing plate 602, it is convenient to connect the tooling body 3 with the module tray 1, and at the same time prevent the tooling body 3 from tipping over, ensuring the fixing effect of the busbar 5 and the battery cell module 2.

[0080] Specifically, the connecting part of this embodiment includes a first elbow clamp 603 arranged on the fixing plate 602 and a second elbow clamp 604 arranged on the module tray 1. A fixing hook 3011 is arranged on the side of the side plate 301 facing the battery cell module 2. When the handle of the first elbow clamp 603 is operated to lock the first elbow clamp 603, the movable hook 6031 on the first elbow clamp 603 can hook the fixing hook 3011 to fix the side plate 301 on the fixing plate 602. The second elbow clamp 604 is arranged on the side of the side plate 301 away from the battery cell module 2. When the handle of the second elbow clamp 604 is operated to lock the second elbow clamp 604, the push rod 6041 on the second elbow clamp 604 can push against the bottom of the side plate 301 to make the side plate 301 closely adhere to the fixing plate 602.

[0081] Through the arrangement of the first elbow clamp 603, the first elbow clamp 603 can fix the side plate 301 on the fixing plate 602. At the same time, through the arrangement of the second elbow clamp 604, the push rod 6041 abuts against the bottom of the side plate 301 to keep the position of the side plate 301 on the top of the support block 601 and closely adhere to the fixing plate 602, so as to ensure that the working body is vertically arranged on the module tray 1. At the same time, the first elbow clamp 603 and the second elbow clamp 604 are convenient to operate and easy to unlock, which is beneficial to the detachable connection of the tooling body 3, thus facilitating the disassembly and assembly of the tooling body 3 by the operating personnel.

[0082] Since the battery cell module 2 can be composed of battery cells of different lengths, in order to adapt to battery cells of different lengths and improve the versatility of the busbar fixing tooling in this embodiment, a plurality of chutes 101 corresponding to each mounting seat 6 one by one are arranged on the module tray 1 of this embodiment, and each chute 101 extends along the width direction of the module tray 1. The support block 601 is slidably arranged in the chute 101, and a slider 605 slidably arranged in the chute 101 is arranged at the bottom of the second elbow clamp 604.

[0083] When the support block 601 moves along the sliding groove 101, the distance between a pair of relatively arranged mounting seats 6 can be changed, that is, the distance between the two tooling bodies 3, so as to adapt to the cells of different lengths and ensure that the busbar 5 can be fixed on the side of the cell module 2. At the same time, the second elbow clamp 604 moves along with the support block 601 through the slider 605 to ensure the fixing and constraining effect of the second elbow clamp 604 on the side plate 301, that is, the tooling body 3. In addition, a plurality of fixing holes 102 for fixing the support block 601 or the slider 605 by connecting pieces are provided in the sliding groove 101, and the fixing holes 102 are arranged at intervals along the extending direction of the sliding groove 101. Through the fixing holes 102, the connecting pieces pass through the corresponding fixing holes 102 and are connected to the support block 601 or the slider 605 to fix the mounting seat 6 and the second elbow clamp 604 at the corresponding positions on the slide rail.

[0084] In specific implementation, due to the movable setting of the mounting seat 6, the position of the tooling body 3 on the module tray 1 can be changed. Therefore, a middle slide rail is also provided on the module tray 1, and the above-mentioned cushion block 104 can slide in the middle sliding groove 101 to ensure that the cushion block 104 can support the bottom cross beam 303 of the tooling body 3 at any position.

[0085] In this embodiment, the second elbow clamp 604 constrains the side plate 301 in the width direction of the module tray 1, while the first elbow clamp 603 mainly constrains the side plate 301 in the height direction. When the movable hook 6031 of the first elbow clamp 603 is hooked on the fixed hook 3011 of the side plate 301, there is a certain movable clearance between the movable hook 6031 and the fixed hook 3011 in the length direction of the module tray 1. This will cause the tooling body 3 and the busbar 5 mounted thereon to move in the length direction of the module tray 1 relative to the cell module 2, resulting in a deviation in the connection between the busbar 5 and the cell module 2.

[0086] To avoid the above situation, a clamping portion 3012 is provided at the bottom of the side plate 301 in this embodiment, and a clamping groove 606 is provided at the top of the support block 601. The clamping portion 3012 can be snapped into the clamping groove 606 to constrain the side plate 301 in the length direction of the module tray 1. Through the cooperative setting of the clamping portion 3012 and the clamping groove 606, when the tooling body 3 is installed on the mounting seat 6, the clamping portion 3012 of the side plate 301 can be snapped into the clamping groove 606 to limit the movement of the tooling body 3 in the length direction of the module tray 1 and ensure the accuracy of the fixed position of the busbar 5 and the cell module 2.

[0087] In summary, for the busbar fixing tooling of this embodiment, through the settings of the module tray 1 and the positioning pins 4 on the tooling body 3, the busbar 5 of this embodiment can be mounted on the tooling body 3 through the cooperation of the positioning holes 502 and the positioning pins 4. After connecting the tooling body 3 to the module tray 1, the busbar 5 can be fixed to the side of the battery cell module 2 where the pole posts are provided, so as to fix the busbar 5 to the battery cell module 2, facilitating the subsequent connection operation between the busbar 5 and the battery cell module 2, and having good practicability.

[0088] The specific usage steps of the busbar fixing tooling of this embodiment are as follows:

[0089] First, place the battery cell module 2 on the module tray 1, make the two sides of the battery cell module 2 with pole posts face the side where the mounting seat 6 is located, and adjust the position of the mounting seat 6.

[0090] After that, lay the tooling body 3 flat and make the positioning pins 4 point upward, cover the busbar 5 on the tooling body 3 from top to bottom, and insert each positioning pin 4 into each positioning hole 502. Then, erect the tooling body 3 so that the clamping portions 3012 at the bottoms of the side plates 301 are clamped into the clamping grooves 606 of the corresponding mounting seats 6.

[0091] Finally, hook the movable hook 6031 of the first elbow clamp 603 on the fixed hook 3011 of the side plate 301 and lock the first elbow clamp 603, and lock the second elbow clamp 604 so that the push rod 6041 presses against the bottom end of the side plate 301 to complete the fixing of the tooling body 3.

[0092] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
