[0029] like Figure 1 As shown, in some embodiments of this application, the cell tray 100 includes a mounting plate 110 and a cell fixing assembly 120. The cell fixing assembly 120 includes two first brackets 130, which are spaced apart on the mounting plate 110 along a first direction X. Each first bracket 130 is provided with two limiting blocks 140, which are spaced apart on the corresponding first bracket 130 along a second direction Y. The four limiting blocks 140 are used to jointly fix one cell 200. The positions of the first brackets 130 in the first direction X and the positions of the limiting blocks 140 in the second direction Y are adjustable.

[0030] The mounting plate 110 extends along the third direction Z in its thickness direction. A cell placement area is formed between the four limiting blocks 140. Each limiting block 140 abuts against the side of the cell 200, and the four limiting blocks 140 together define the position of the cell 200 in the circumferential direction. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. The cell 200 has a square structure. The length of the cell 200 extends along the second direction Y, the width extends along the first direction X, and the thickness extends along the third direction Z. That is, two first supports 130 are spaced apart along the length direction of the cell 200, and two limiting blocks 140 on each first support 130 are spaced apart along the width direction of the cell 200.

[0031] The battery cell tray 100 of this application embodiment includes a battery cell fixing assembly 120. The battery cell fixing assembly 120 includes two first brackets 130. Each first bracket 130 is provided with two limiting blocks 140. The position of the first bracket 130 in the first direction X is adjustable, and the position of the limiting block 140 in the second direction Y is adjustable, so as to adjust the position of the limiting block 140 in the first direction X and the second direction Y to be compatible with battery cells 200 of different specifications.

[0032] like Figure 1 As shown, the mounting plate 110 includes a frame 111 and a plate body 112. The plate body 112 is disposed on the frame 111, and the thickness direction of the plate body 112 extends along the third direction Z. The cell fixing assembly 120 is disposed on the plate body 112.

[0033] The frame 111 is made of aluminum alloy. The plate 112 is fixed to the frame 111 by threaded parts. A pair of handles 1124 are provided on the plate 112. The pair of handles 1124 are provided on the two edges of the plate 112 along the first direction X, which facilitates the loading and unloading of the plate 112 and the handling of the mounting plate 110.

[0034] like Figure 1 As shown, in some embodiments of this application, two battery cell fixing assemblies 120 are provided, and the two battery cell fixing assemblies 120 are arranged at intervals along the second direction Y. With this arrangement, the battery cell tray 100 can connect two battery cells 200 in one cycle, and the spacing between the battery cells 200 is reasonable, which can improve the transfer efficiency or processing efficiency of the battery cells 200.

[0035] In other embodiments, the number of cell fixing assemblies 120 may also be one, three, or four, etc.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the mounting plate 110 is provided with a first mounting hole 1121, and the first bracket 130 is provided with a narrow first mounting groove 131. The length direction of the first mounting groove 131 extends along the first direction X. The first mounting groove 131 and the first mounting hole 1121 are configured to fix the first bracket 130 to the mounting plate 110 by means of a threaded component.

[0037] The plate 112 has a first surface 1125 and a second surface 1126 on both sides along the third direction Z. The cell fixing assembly 120, the handle 1124, and the gripper assembly 150 described below are all disposed on the first surface 1125. The first mounting hole 1121 can be a blind hole disposed on the first surface 1125 or a through hole penetrating the plate 112. Multiple first mounting holes 1121 can be provided, and multiple first mounting holes 1121 are spaced apart along the first direction X. Alternatively, only one first mounting hole 1121 can be provided.

[0038] The first mounting groove 131 extends through the first bracket 130 along the third direction Z. The first mounting groove 131 is correspondingly provided with the first mounting hole 1121. The first mounting groove 131 and the corresponding first mounting hole 1121 constitute the first mounting component 133. The first mounting component 133 is used to realize the assembly of the first bracket 130 and the mounting plate 110.

[0039] The first support 130 is covered with a silicone sleeve, which not only reduces the risk of the first support 130 scratching the surface of the battery cell 200, but also provides insulation protection during the transportation of the battery cell 200.

[0040] By setting the first mounting groove 131 and the first mounting hole 1121, the position of the first bracket 130 can be adjusted along the first direction X. Then, a threaded part is used to pass through the first mounting groove 131 and screwed into the first mounting hole 1121, so that the first bracket 130 can be fixed to the mounting plate 110. By changing the relative position of the first mounting hole 1121 and the first mounting groove 131 in the first direction X, the position of the first bracket 130 can be adjusted within a certain range, thereby adapting to different specifications of battery cells 200.

[0041] In some embodiments of this application, a first mounting groove 131 and two first mounting holes 1121 spaced apart along a first direction X constitute a first mounting assembly 133. Each first bracket 130 is assembled with a mounting plate 110 by four first mounting assemblies 133. The four first mounting grooves 131 are spaced apart along a second direction Y, wherein two first mounting grooves 131 are located at the edge of one end of the first bracket 130 along the second direction Y, and the other two first mounting grooves 131 are located at the edge of the first bracket 130 at the other end along the second direction Y.

[0042] In other embodiments, the number and position of the first mounting slots 131 can also be flexibly adjusted according to specific circumstances.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the first bracket 130 is provided with a narrow second mounting groove 132, the length direction of the second mounting groove 132 extends along the second direction Y, and the limiting block 140 is provided with a second mounting hole 141. The second mounting groove 132 and the second mounting hole 141 are configured to fix the limiting block 140 to the first bracket 130 by means of a threaded component.

[0044] The second mounting groove 132 passes through the first bracket 130 along the third direction Z. The second mounting groove 132 is correspondingly provided with the second mounting hole 141. The second mounting groove 132 and the corresponding second mounting hole 141 constitute the second mounting component 134. The second mounting component 134 is used to realize the assembly of the limiting block 140 and the first bracket 130.

[0045] In one embodiment, the mounting plate 110 is provided with a plurality of fourth mounting holes, which are spaced apart along the second direction Y. The plurality of fourth mounting holes are correspondingly provided with the second mounting groove 132. The threaded part passes through the second mounting hole 141 and the second mounting groove 132 and engages with the fourth mounting hole to fix the limiting block 140 to the first bracket 130 and the mounting plate 110. The position of the limiting block 140 is adjusted by engaging with different fourth mounting holes.

[0046] As another implementation, a self-locking screw is used to pass through the second mounting hole 141 and engage with the second mounting groove 132 to fix the limiting block 140 to the first bracket 130. The position of the limiting block 140 is adjusted by changing the position of the threaded part in the second mounting groove 132.

[0047] By providing the second mounting slot 132 and the second mounting hole 141, the position of the limiting block 140 can be adjusted within a certain range to accommodate batteries of different specifications.

[0048] like Figure 3 As shown, in some embodiments of this application, a second mounting slot 132 and a second mounting hole 141 are configured to form a second mounting assembly 134. Each limiting block 140 is assembled with the first bracket 130 through two second mounting assemblies 134. The two second mounting slots 132 are spaced apart along the first direction X.

[0049] In other embodiments, the number and position of the second mounting slots 132 can also be flexibly adjusted according to specific circumstances.

[0050] like Figure 3 As shown, in some embodiments of this application, the limiting block 140 includes a first limiting surface 142 and a second limiting surface 143. The first limiting surface 142 and the second limiting surface 143 are not parallel to each other. The first limiting surface 142 and the second limiting surface 143 are respectively used to abut against two adjacent sides of the battery cell 200.

[0051] The first limiting surface 142 and the second limiting surface 143 are arranged perpendicularly between each other. Each limiting block 140 is used to fix one corner of the battery cell 200. The first limiting surface 142 is used to abut against the side of the battery cell 200 along the first direction X, and the second limiting surface 143 is used to abut against the side of the battery cell 200 along the second direction Y.

[0052] With this configuration, the four corners of the battery cell 200 can be fixed by the four limiting blocks 140 respectively, leaving space on both sides of the battery cell 200 in the first direction X, which is convenient for arranging the subsequent gripper assembly 150.

[0053] In other embodiments, the first limiting surface 142 and the second limiting surface 143 may also be inclined; the limiting block 140 may also include only one limiting surface, and each limiting block 140 abuts against one side of the battery cell 200.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the first mounting groove 131 and the second mounting groove 132 are spaced apart along the second direction Y, and the first mounting groove 131 is disposed outside the second mounting groove 132.

[0055] That is, the first mounting groove 131 is located near the edge of the first bracket 130, and the second mounting groove 132 is located on the side of the first mounting groove 131 away from its same side edge.

[0056] This configuration allows for the avoidance of the space between the two limiting blocks 140, utilizing the tab that accommodates the battery cell 200.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the cell fixing assembly 120 further includes a pair of gripper assemblies 150, which are arranged opposite to each other along the second direction Y. The gripper assemblies 150 are used to abut against the top surface of the cell 200 to press the cell 200 against the mounting plate 110; wherein the position of the gripper assemblies 150 in the second direction Y is adjustable.

[0058] The cell fixing assembly 120 also includes a third bracket 121, which is disposed on the mounting plate 110. A pair of gripper assemblies 150 are both mounted on the third bracket 121. The third bracket 121 has a narrow third mounting groove, the length of which extends along the second direction Y. The second bracket 151 of the gripper assembly 150 has a third mounting hole. The position adjustment method of the gripper assembly 150 is the same as that of the limiting block 140, and will not be described further here.

[0059] The gripper assembly 150 can abut against the battery cell 200 along the third direction Z, pressing the battery cell 200 against the first surface 1125 of the plate 112 to fix the position of the battery cell 200 in the third direction Z; by adjusting the position of the gripper assembly 150 in the second direction Y, it can adapt to battery cells 200 of different specifications.

[0060] like Figure 5 and Figure 6As shown, in some embodiments of this application, the gripper assembly 150 includes a second bracket 151, a rocker arm 152, and an elastic member 153. The second bracket 151 is disposed on the mounting plate 110, and the rocker arm 152 is rotatably mounted on the second bracket 151. The two ends of the rocker arm 152 are a pressing part 1521 and a mating part 1522, respectively. The pressing part 1521 is used to press the battery cell 200. The two ends of the elastic member 153 are respectively connected to the rocker arm 152 and the second bracket 151, and are used to drive the pressing part 1521 to press the battery cell 200. The mating part 1522 is provided with a roller 154, which is used to cooperate with an external mechanical finger.

[0061] The second bracket 151 is disposed on the first surface 1125 of the plate 112. The middle part of the rocker arm 152 is rotatably mounted on the second bracket 151 via a pin around a first axis P. The first axis P extends along a first direction X. The side of the rocker arm 152 closer to the battery cell 200 is a pressing part 1521, and the side farther from the battery cell 200 is a mating part 1522. Under the pressure of an external mechanical finger, the mating part 1522 descends to drive the pressing part 1521 to open and release the battery cell 200; when there is no external force, the pressing part 1521 presses the battery cell 200 under the elastic force of the elastic member 153.

[0062] Roller 154 is rotatably mounted on pressing part 1521. Mechanical finger presses roller 154 and drives rocker arm 152 to release battery cell 200. Elastic member 153 is a tension spring. One end of elastic member 153 is connected to the root of second bracket 151, and the other end is connected to a segment of pressing part 1521 of rocker arm 152. Pressing part 1521 presses battery cell 200 under the tension of tension spring.

[0063] The gripper assembly 150 also includes a first buffer 1523 and a second buffer 155. The first buffer 1523 is fitted onto the pressing surface of the pressing part 1521 and abuts against the top surface of the battery cell 200 to buffer the impact force on the battery cell 200 during the pressing action. The second buffer 155 is disposed on the second bracket 151 and abuts against the bottom side of the pressing part 1521 to buffer the shaking and swaying phenomenon during the swinging process of the rocker arm 152 from the open state to the pressed state. The first buffer 1523 and the second buffer 155 can be made of polyurethane or rubber.

[0064] By setting the roller 154, the friction during the pressing process can be reduced, thereby reducing the wear on the mechanical finger and rocker arm 152 when the mechanical finger presses the mating part 1522 repeatedly, and improving the service life of the gripper assembly 150.

[0065] In some embodiments of this application, the bottom of the mounting plate 110 is provided with a magnet for engaging with an external magnetic drive delivery line.

[0066] The magnet is disposed on the second surface 1126 of the plate 112. The magnet can be fixed to the frame 111 or the plate 112.

[0067] This configuration enables the conveying of the cell tray 100 on the magnetic drive conveyor line, thereby efficiently transferring the cell 200.

[0068] like Figure 6 As shown, in some embodiments of this application, the cell tray 100 further includes a cell mold 160 for adjusting the position of the first bracket 130 in the first direction X and the position of the limiting block 140 in the second direction Y.

[0069] The outer dimensions of the cell mold 160 are the same as those of the corresponding specification cell 200. It is used to replace the cell 200 and is placed on the mounting plate 110 in advance to adjust the position of the four limit blocks 140.

[0070] This configuration makes it easy to adjust the position of the limit block 140 and quickly adapt to different specifications of battery cells 200.

[0071] In some embodiments of this application, the mounting plate 110 is provided with a third buffer 1122, which is disposed between the two first supports 130. The third buffer 1122 is provided with a first positioning hole 1123, the cell mold 160 is provided with a second positioning hole 161, and the cell tray 100 also includes a positioning pin. The positioning pin passes through the second positioning hole 161 and is inserted into the first positioning hole 1123 to fix the position of the cell mold 160.

[0072] The second positioning hole 161 penetrates the cell mold 160 along the third direction Z. The third bracket 121 is provided with a groove structure. The third buffer 1122 is installed in the groove structure. The first positioning hole 1123 penetrates the third buffer 1122 along the third direction Z. The material of the third buffer 1122 is foam, which is used to buffer the impact force on the cell 200 during the placement and pressing of the cell 200.

[0073] The positioning pin and the corresponding first positioning hole 1123 and second positioning hole 161 constitute a positioning component. The cell mold 160 is fixed on the mounting plate 110 by the two positioning components. The two positioning components are spaced apart along the second direction Y to avoid deviation of the position of the cell mold 160.

[0074] By setting a positioning pin through the cell mold 160 and the third buffer 1122, the relative position of the cell mold 160 on the mounting plate 110 can be fixed in advance, and then the relative positions of the four limit blocks 140 can be adjusted accordingly, thereby improving the positional accuracy of the limit blocks 140 and thus accurately adapting to cell 200 of different specifications.

[0075] Some embodiments of the battery cell production line in this application include a battery cell tray 100.

[0076] Since the cell tray 100 of this application embodiment is compatible with different specifications of cell 200, it can be applied at the process connection point to enable the cell production line 200 to adapt to multiple specifications of cell 200, thereby reducing the manufacturing cost of cell 200.

[0077] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
