[0026] Detailed Implementation

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] The following description, with reference to the accompanying drawings, describes the battery cell positioning fixture according to this utility model.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, a battery cell positioning fixture is proposed. The battery cell positioning fixture includes a mounting plate 1 and a positioning mechanism. The mounting plate 1 has a clearance channel 11 extending along the conveying direction of the battery cell 100. The clearance channel 11 is used to avoid the transfer mechanism, which is used to support and transfer the battery cell 100. The positioning mechanism includes two first positioning components 21 and two second positioning components 22 disposed on the mounting plate 1. The two first positioning components 21 are arranged at intervals along the length direction of the clearance channel 11, and the two second positioning components 221 are arranged at intervals along the width direction of the clearance channel 11. The distance between the two first positioning components 21 is adjustable and can limit the battery cell 100 in the length direction. Similarly, the distance between the two second positioning components 22 can also be adjusted to limit the battery cell 100 in the width direction.

[0030] In the existing technology, when positioning battery cells 100 of different specifications, the fixing block used to position the battery cells 100 usually needs to be removed and installed in other positions in order to adapt to the different specifications of battery cells 100. This is complicated to operate, has poor versatility, and cannot be conveniently adapted to different specifications of battery cells 100.

[0031] Therefore, this application proposes a versatile battery cell positioning fixture. The process of adjusting the battery cell positioning fixture for different models of battery cells 100 using this embodiment is as follows:

[0032] Since the sizes of different models of battery cells 100 vary, the positions of the first positioning component 21 and the second positioning component 22 on the mounting plate 1 need to be adjusted accordingly. First, the two second positioning components 22 slide in the width direction, and the two first positioning components 21 slide in the length direction to adjust their positions on the mounting plate 1, better adapting to battery cells 100 of different sizes and facilitating subsequent processing of the battery cells 100. Then, the transfer mechanism moves along the clearance channel 11 and transfers the battery cell 100 to a positioning fixture for positioning. Finally, after positioning, the battery cell 100 can be transferred to the next process via the transfer mechanism. In this embodiment, the distance between the two first positioning components 21 and the two second positioning components 22 is adjustable, adapting to various sizes of battery cells 100, and the battery cell positioning fixture has good versatility. The length direction of the clearance channel 11 is... Figure 2 The left and right directions in the middle.

[0033] Furthermore, such as Figure 1 As shown, the mounting plate 1 has two clearance channels 11 spaced apart along the front-to-back direction. Each clearance channel 11 can be equipped with two cell positioning fixtures, and each cell positioning fixture can position the cell 100 to improve the positioning efficiency of the cell 100 per unit time. The number of clearance channels 11 can be set according to actual needs.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, the first positioning component 21 has a first elongated hole 212 extending along the length direction, and the second positioning component 22 has a second elongated hole 222 extending along the width direction. The mounting plate 1 has a plurality of first mounting holes 12 spaced apart along the length direction and a plurality of second mounting holes 13 spaced apart along the width direction. The cell positioning fixture also includes a locking member 3, which is used to pass through the first mounting holes 12 and the first elongated hole 212 to lock the first positioning component 21 and the mounting plate 1. The locking member 3 is also used to pass through the second mounting holes 13 and the second elongated hole 222 to lock the second positioning component 22 and the mounting plate 1. Furthermore, when it is necessary to adjust the position of the first positioning component 21 and the second positioning component 22 on the mounting plate 1, the locking member 3 can be loosened or removed to avoid affecting the position adjustment of the first positioning component 21 and the second positioning component 22. The length direction is... Figure 2 The left and right directions, the width direction, that is Figure 2 The front and back directions in the middle.

[0035] Specifically, when positioning different models of battery cells 100, the positions of the first positioning component 21 and the second positioning component 22 on the mounting plate 1 need to be adjusted according to the size of the battery cell 100. Specifically, the first positioning component 21 will slide relative to the mounting plate 1 in the left-right direction, and the second positioning component 22 will slide relative to the mounting plate 1 in the front-back direction. At this time, the locking member 3 can slide back and forth along the first elongated hole 212 and the second elongated hole 222 to facilitate position adjustment in the left-right and front-back directions, making it convenient for the battery cell positioning fixture to subsequently position the battery cell 100. The battery cell positioning fixture of this application can adapt to battery cells 100 of different sizes and has good versatility. The locking member 3 uses screws as used in the prior art, and the locking member 3 is threadedly engaged with multiple first mounting holes 12 and multiple second mounting holes 13 to achieve a stable lock on the first positioning component 21 and the second positioning component 22.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the first positioning component 21 includes two first positioning members 211 spaced apart along the width direction of the mounting plate 1, and the second positioning component 22 includes two second positioning members 221 spaced apart along the length direction of the mounting plate 1. Each first positioning member 211 has a first elongated hole 212, and each second positioning member 221 has a second elongated hole 222. In this embodiment, two first positioning members 211 are provided on each of the left and right sides of the battery cell 100 along the left-right direction. Two second positioning members 221 are provided on each of the front and rear sides of the battery cell 100 along the front-back direction, which can further improve the positioning accuracy of the battery cell 100 and achieve precise positioning of the battery cell 100.

[0037] In this embodiment, there are multiple first elongated holes 212 spaced apart along the length of the mounting plate 1, and multiple second elongated holes 222 spaced apart along the width of the mounting plate 1. Figure 4 and Figure 5 As shown, in this embodiment, each first positioning member 211 has two first elongated holes 212, and each second positioning member 221 has two second elongated holes 222. This is to prevent the first positioning member 211 from sliding in the left-right direction and to prevent the second positioning member 221 from sliding in the front-back direction, thus ensuring the positioning accuracy of the battery cell 100. The number of first elongated holes 212 and second elongated holes 222 can be adjusted according to actual needs.

[0038] like Figure 2 and Figure 5 As shown, in this embodiment, the two second positioning members 221, which are spaced apart along the width direction, are provided with a platform 223 for supporting the battery cell 100 on their opposite sides. The top surface of the platform 223 is lower than the top surface of the second positioning member 221.

[0039] In this embodiment, the second positioning component 221 is provided with a placement platform 223 to facilitate the placement of the battery cell 100. When the battery cell 100 needs to be positioned, it is first placed on the placement platform 223 by a transfer mechanism. After positioning, the battery cell 100 can be transferred to the next process by the transfer mechanism. Since different models of battery cells 100 have different sizes, when dealing with different models of battery cells 100, the positions of the first positioning component 21 and the second positioning component 22 on the mounting plate 1 need to be adjusted accordingly. First, the distance between the two second positioning components 221 that are spaced apart in the front-back direction is adjusted. Next, the distance between the two first positioning components 211 that are spaced apart in the left-right direction is adjusted to ensure that the battery cell 100 can be placed on the placement platform 223 for positioning.

[0040] like Figure 4 As shown, in this embodiment, both the first positioning member 211 and the second positioning member 221 are block structures. In the first positioning assembly 21, the opposite sides of the two first positioning members 211, which are spaced apart along the length direction, are provided with first chamfers 213. When it is necessary to position different types of battery cells 100, the two first positioning members 211 can move closer or further apart to adapt to different specifications of battery cells 100. The first chamfers 213 can straighten the battery cells 100 and ensure that the battery cells 100 do not tilt.

[0041] like Figure 5 As shown in this embodiment, in the second positioning component 22, the two second positioning members 221, which are spaced apart along the width direction, are each provided with a second chamfer 224 on their opposite sides. During the adjustment process for different models of battery cells 100, the two second positioning members 221 can move closer or further apart to adapt to different specifications of battery cells 100. The second chamfer 224 can straighten the battery cell 100, ensuring that the position of the battery cell 100 does not change, and avoiding the risk of being bumped when the battery cell 100 is lifted due to improper positioning. Among them, the lifting of the battery cell 100 is a step in the transfer mechanism when transferring the battery cell 100, and the tilt angles of the first chamfer 213 and the second chamfer 224 can be set according to actual needs.

[0042] like Figure 4 As shown, in this embodiment, the first positioning member 211 is also provided with a weight reduction notch 214, which reduces the weight of the first positioning member 211 without affecting the positioning effect of the first positioning member 211 on the battery cell 100 in the left and right directions.

[0043] In this embodiment, both the first positioning member 211 and the second positioning member 221 are made of thermoplastic resin. Specifically, the first positioning member 211 and the second positioning member 221 can be made of POM (Polyoxymethylene) block, i.e., polyoxymethylene material, to avoid the first positioning member 211 and the second positioning member 221 causing impact damage to the battery cell 100 during the positioning process.

[0044] like Figure 4 and Figure 5 As shown, in this embodiment, the locking member 3 includes a plug-in portion and a limiting portion. The first positioning member 211 is also provided with a first countersunk hole 215 communicating with the first elongated hole 212, and the second positioning member 221 is also provided with a second countersunk hole 225 communicating with the second elongated hole 222. The first countersunk hole 215 and the second countersunk hole 225 are both used to accommodate the limiting portion to avoid interference between the limiting portion of the locking member 3 and other components. The plug-in portion passes through the first elongated hole 212 and cooperates with the first mounting hole 12 to lock the first positioning member 211 and the mounting plate 1. The plug-in portion passes through the second elongated hole 222 and cooperates with the second mounting hole 13 to lock the second positioning member 221 and the mounting plate 1.

[0045] The locking element 3 is multiplied, with multiple locking elements 3 inserted into both the first elongated hole 212 and the second elongated hole 222. Through the threaded engagement of the locking element 3 with the first mounting hole 12 and the second mounting hole 13, the movement range of the first positioning element 211 and the second positioning element 221 can be limited. Preferably, if the first positioning element 211 has only one first elongated hole 212 and the second positioning element 221 has only one second elongated hole 222, then two locking elements 3 are inserted into each of the first elongated hole 212 and the second elongated hole 222 to provide good guidance, preventing the first positioning element 211 from sliding in the left-right direction and the second positioning element 221 from sliding in the front-back direction, thus ensuring the accuracy of the battery cell 100 positioning.
