[0001] The present application relates to the technical field of battery cell loading and unloading, and in particular to a battery cell loading and unloading workstation. Background Art

[0002] With the maturity and development of battery technology, batteries are used more and more widely. Batteries consist of multiple cells, and the quality of the battery is closely related to the quality of the cells. In the process of cell production, it is usually necessary to test the cells, and then load or unload qualified and unqualified cells on the production line. However, in the related art, the cell loading and unloading workstation cannot flip the polarity of the cell, resulting in low efficiency of loading and unloading the cell. Summary of the invention

[0004] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0005] An embodiment of the present application provides a battery cell loading and unloading workstation, which includes a frame, a first tray, a second tray and a battery cell gripper. The first tray is used to store test batteries, and the second tray is used to store qualified batteries and unqualified batteries. The battery cell gripper is movably arranged on the frame to move unqualified test batteries on the first tray to the second tray or move qualified batteries on the second tray to the first tray, wherein the battery cell gripper includes a first driving member, a rotating mechanism and a clamping mechanism.

[0006] The battery cell loading and unloading workstation provided in the embodiment of the present application has a driving end of the first driving member connected to the rotating mechanism to drive the rotating mechanism and the clamping mechanism to move in the first direction, and can quickly drive the rotating mechanism and the clamping mechanism to move in the first direction to reduce the waiting time of the battery cell gripper during the movement process, thereby improving the handling efficiency of the battery cell loading and unloading workstation, and the rotating end of the rotating mechanism is connected to the clamping mechanism to drive the clamping mechanism to rotate. The clamping mechanism is suitable for clamping battery cells. On the one hand, it can cause the polarity of the battery cell clamped by the clamping mechanism to be reversed, thereby reducing the waiting time for the polarity reversal of the battery cell required by manual or additional processes, thereby improving the operation efficiency of the battery cell loading and unloading workstation, and on the other hand, it can cause the battery cell to enter the slot of the first tray or the second tray at a suitable angle, so that the battery cell enters the tray slot more smoothly, thereby reducing the probability of incorrect placement of the battery cell and improving the operation accuracy of the battery cell loading and unloading workstation.

[0007] Optionally, the clamping mechanism includes a mounting frame, a second driving member and a clamping jaw, the mounting frame is connected to the rotating end of the rotating mechanism, the second driving member is arranged on the mounting frame, and the second driving member is connected to the clamping jaw to drive the clamping jaw to clamp or release.

[0008] The second driving member is connected to the clamping jaw to drive the clamping jaw to clamp or release. Through the connection between the second driving member and the clamping jaw, precise control of the clamping jaw can be achieved, so that it can automatically clamp or release the object according to preset programs and instructions. This greatly improves the automation level of the battery cell loading and unloading workstation, reduces manual intervention, and thus improves production efficiency and product quality. Moreover, by driving the clamping jaw to clamp or release through the second driving member, high-precision positioning of the clamping jaw can be achieved by precisely controlling the movement of the second driving member, which helps to ensure that the clamping jaw can be accurately placed in a predetermined position when grasping or releasing an object, thereby improving the accuracy and reliability of battery cell handling.

[0009] Optionally, the clamp includes a first clamping portion and a second clamping portion. Along the second direction, the first clamping portion is movably arranged on the mounting frame to approach or move away from the second clamping portion.

The first connecting portion is provided with a first sliding groove inclined compared to the first direction, and the first clamping portion is provided with a first pin that cooperates with the first sliding groove.

[0010] The first connecting portion is provided with a first sliding groove inclined compared to the first direction, and the first clamping portion is provided with a first pin matched with the first sliding groove, so that the clamping claw can maintain a stable and accurate position when clamping the battery cell, avoiding damage to the battery cell or unstable clamping due to position deviation. The mobility of the first clamping portion along the second direction enables the clamping claw to be flexibly adjusted according to the size and shape of different battery cells. This highly adaptable design enables the clamping mechanism to handle more types of battery cells, improving the versatility and practicality of the workstation.

[0011] Optionally, along the second direction, the second clamping portion can be movably arranged on the mounting frame to approach or move away from the first clamping portion, and the first connecting portion is provided with a second sliding groove inclined compared to the first direction, and the second clamping portion is provided with a second pin cooperating with the second sliding groove, and the inclination direction of the second sliding groove is different from the inclination direction of the second sliding groove.

[0012] The second connecting part is provided with a second sliding groove inclined in comparison with the first direction, and the second clamping part is provided with a second pin cooperating with the second sliding groove, so that the clamping claw can maintain a stable and accurate position when clamping the battery cell, avoiding damage to the battery cell or unstable clamping due to position deviation. The mobility of the second clamping part along the second direction enables the clamping claw to be flexibly adjusted according to the size and shape of different battery cells.

[0014] The workstation also includes a feeding track group, and the first tray is slidably arranged on the feeding track group, which can transport the battery cells on the first tray to the bottom of the battery cell gripper.

[0015] Optionally, the second tray includes an upper line area and a lower line area, the upper line area and the lower line area are located on the same side of the feeding track group, the upper line area is closer to the feeding track group than the lower line area, the upper line area is suitable for storing qualified battery cells, and the lower line area is used to store unqualified battery cells.

[0016] The upper line area is closer to the feeding track group than the lower line area. After the battery cell gripper clamps the unqualified battery cells on the first tray, it transfers the unqualified battery cells to the lower line area. At this time, the battery cell gripper needs to clamp the same number of qualified battery cells and transfer them to the first tray. In this way, the battery cell gripper can clamp the same number of qualified battery cells on the return trip and then transfer them to the first tray. This reduces the moving distance of the battery cell gripper and improves the operating efficiency of the battery cell loading and unloading workstation.

[0017] Optionally, the upper line area includes a plurality of upper line tray slots, the lower line area includes a plurality of lower line tray slots, and the upper line tray slots have positioning structures that cooperate with the battery cells.

[0019] Optionally, the positioning structure is constructed as a step portion arranged at the bottom of the upper line tray slot, and the upper line tray slot includes a first section and a second section. The first section is closer to the opening of the upper line tray slot than the second section, and the cross-sectional area of ​​the first section is larger than the cross-sectional area of ​​the second section to form a step portion.

[0020] Compared with the second section close to the opening of the upper line tray slot, the cross-sectional area of ​​the first section is larger than the cross-sectional area of ​​the second section to form a step portion, which can more accurately fix the battery cell in the upper line tray slot, and can ensure that the battery cell remains in the correct position and posture in the tray slot of the upper line area, so that the battery cell maintains the correct position and posture during the loading process, thereby improving the operation accuracy of the battery cell loading and unloading workstation.

[0041] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0042] With the maturity and development of battery technology, batteries are used more and more widely. Batteries consist of multiple cells, and the quality of batteries is closely related to the quality of the cells.

[0043] In the process of battery cell production, it is usually necessary to test the battery cells, and then load or unload qualified and unqualified battery cells on the production line. The battery cell loading and unloading workstation is mainly responsible for unloading unqualified battery cells on the conveyor tray after the battery cell testing is completed, and loading qualified battery cells into the empty space of unqualified battery cells after unloading from the conveyor tray.

[0044] During the process of loading and unloading the battery cells, some of the battery cells may have their polarity reversed due to reasons such as transmission, that is, the positions of the positive and negative poles of the battery cells on the tray are reversed. However, in the related art, the battery cell loading and unloading workstation cannot reverse the polarity of the battery cells, resulting in low efficiency of loading and unloading the battery cells.

[0045] In view of this, in order to solve the technical problem that the battery cell loading and unloading workstation cannot flip the polarity of the battery cells, some embodiments of the present application provide a battery cell loading and unloading workstation including a frame, a first tray, a second tray and a battery cell gripper.

[0046] The first tray is used to store test cells, and the second tray is used to store qualified cells and unqualified cells. The cell gripper is movably arranged on the frame to move unqualified cells on the first tray to the second tray or to move qualified cells on the second tray to the first tray, wherein the cell gripper includes a first driving member, a rotating mechanism and a clamping mechanism, wherein the first driving member is arranged on the frame, the driving end of the first driving member is connected to the rotating mechanism to drive the rotating mechanism and the clamping mechanism to move in the first direction, the rotating end of the rotating mechanism is connected to the clamping mechanism to drive the clamping mechanism to rotate, and the clamping mechanism is suitable for clamping the cells.

[0047] In the above scheme, the first driving member can drive the rotating mechanism and the clamping mechanism to move in the first direction, the clamping mechanism can clamp the battery cell, the rotating end of the rotating mechanism is connected to the clamping mechanism, the rotating mechanism can drive the clamping mechanism to rotate, and when the clamping mechanism clamps the battery cell, the rotating mechanism can make the battery cell clamped by the clamping mechanism complete polarity reversal.

[0048] For the convenience of description, the following embodiments are described by taking a battery cell loading and unloading workstation according to one embodiment of the present application as an example.

[0049] Please refer to Figures 1 to 8 , Figure 1 This is a structural diagram of a battery cell loading and unloading workstation 100 provided in an embodiment of the present application. Figure 2 for Figure 1 A top view of Figure 3 The structure of the cell gripper 140 is shown. Figure 4 The structure of the clamping mechanism 143 is shown. Figure 5 The structure of the sliding mechanism 230 is shown. Figure 6 for Figure 5Side view of Figure 7 An upper line region 131 and a lower line region 132 are shown, Figure 8 The structures of the first section 221 and the second section 222 are shown.

[0050] In the embodiment of the present application, the cell loading and unloading workstation 100 includes a frame 110, a first tray 120, a second tray 130 and a cell gripper 140. The first tray 120 is used to store test cells, and the second tray 130 is used to store qualified cells and unqualified cells. The cell gripper 140 is movably arranged on the frame 110 to move the unqualified cells on the first tray 120 to the second tray 130 or to move the qualified cells on the second tray 130 to the first tray 120. , wherein the battery cell gripper 140 includes a first driving member 141, a rotating mechanism 142 and a clamping mechanism 143. The first driving member 141 is arranged on the frame 110. The driving end 141A of the first driving member 141 is connected to the rotating mechanism 142 to drive the rotating mechanism 142 and the clamping mechanism 143 to move in the first direction X. The rotating end 142A of the rotating mechanism 142 is connected to the clamping mechanism 143 to drive the clamping mechanism 143 to rotate. The clamping mechanism 143 is suitable for clamping the battery cell.

[0051] The first tray 120 is used to store test cells. After the cell production is completed, the cell will be subjected to OCV testing to determine whether the cell is qualified. The test cells are then transported to the loading and unloading workstation 100 through the first tray 120 to be loaded or unloaded. In other words, the test cells may include qualified cells and unqualified cells, or all test cells may be qualified cells or all unqualified cells.

[0052] The second tray 130 is used to store qualified cells and unqualified cells. The cell gripper 140 can be movably arranged on the frame 110, that is, the cell gripper 140 can be moved relative to the frame 110. When the cell gripper 140 moves, the position of the frame 110 can remain fixed. The cell gripper 140 can grab the cells. For example, the cell gripper 140 can move the unqualified cells on the first tray 120 to the second tray 130, that is, off-line, and can also move the qualified cells on the second tray 130 to the first tray 120, that is, on-line. In addition, in some possible embodiments, there are multiple first trays 120, and multiple first trays 120 are transported on the production line. When the first first tray 120 is transferred to the battery cell loading and unloading workstation 100, both the qualified battery cells and the unqualified battery cells on the first first tray 120 can be moved to the second tray 130, and then for the second first tray 120 that arrives at the battery cell loading and unloading workstation 100, the transport gripper can only remove the unqualified battery cells to the second tray 130, and the transport gripper transports the qualified battery cells on the second tray 130 to the first tray 120, thereby completing the loading and unloading of the unqualified battery cells in the first tray 120 on the production line.

[0053] The battery cell gripper 140 includes a first driving member 141, a rotating mechanism 142 and a clamping mechanism 143. The clamping mechanism 143 is used to clamp the battery cell. The driving end 141A of the first driving member 141 is connected to the rotating mechanism 142, and the rotating mechanism 142 and the clamping mechanism 143 are connected. The first driving member 141 can drive the rotating mechanism 142 and the clamping mechanism 143 to move in the first direction X (actually also the vertical direction). The rotating end 142A of the rotating mechanism 142 is connected to the clamping mechanism 143. The rotating mechanism 142 can drive the clamping mechanism 143 to rotate. For example, the rotating mechanism 142 can drive the clamping mechanism 143 to rotate 90 degrees, 180 degrees, 270 degrees, 360 degrees and the like. On the one hand, the polarity of the battery cell is flipped so that the battery cell enters the first tray 120 with a preset polarity, so that the battery cell in the first tray 120 can enter the next process. On the other hand, the angle of the battery cell can also be adjusted so that the clamping mechanism 143 can place the battery cell into the slot of the first tray 120 or the second tray 130 at a suitable angle or posture, thereby improving the handling efficiency of the battery cell gripper 140.

[0054] Specifically, the driving end 141A of the first driving member 141 is connected to the rotating mechanism 142 to drive the rotating mechanism 142 and the clamping mechanism 143 to move in the first direction X. The rotating mechanism 142 and the clamping mechanism 143 can be quickly driven to move in the first direction X to reduce the waiting time of the battery cell gripper 140 during the movement process and improve the handling efficiency of the battery cell loading and unloading workstation 100. The rotating end 142A of the rotating mechanism 142 is connected to the clamping mechanism 143 to drive the clamping mechanism 143 to rotate. The clamping mechanism 143 is suitable for clamping battery cells. On the one hand, the polarity of the battery cell clamped by the clamping mechanism 143 can be reversed, reducing the waiting time for the polarity reversal of the battery cell required by manual labor or additional processes, thereby improving the operation efficiency of the battery cell loading and unloading workstation 100. On the other hand, the battery cell can enter the slot of the first tray 120 or the second tray 130 at a suitable angle, so that the battery cell enters the tray slot more smoothly, reducing the probability of incorrect placement of the battery cell and improving the operation accuracy of the battery cell loading and unloading workstation 100.

[0055] Please refer to Figures 1 to 8 In this embodiment, the clamping mechanism 143 includes a mounting frame 150, a second driving member 160 and a clamping jaw 170. The mounting frame 150 is connected to the rotating end 142A of the rotating mechanism 142. The second driving member 160 is disposed on the mounting frame 150. The second driving member 160 is connected to the clamping jaw 170 to drive the clamping jaw 170 to clamp or release.

[0056] The clamping mechanism 143 includes a mounting frame 150, a second driving member 160 and a clamping jaw 170. The mounting frame 150 is connected to the rotating end 142A of the rotating mechanism 142, that is, the rotating mechanism 142 can rotate the mounting frame 150. The second driving member 160 and the clamping jaw 170 are actually arranged on the mounting frame 150, fixedly connected to the mounting frame 150 and rotated with the rotation of the mounting frame 150. Thus, the rotating mechanism 142 can rotate the mounting frame 150, the second driving member 160 and the clamping jaw 170 together. The second driving member 160 is connected to the clamping jaw 170 to control the clamping or loosening of the clamping jaw 170. For example, the clamping jaw 170 can be moved to the unqualified battery cell of the first tray 120, the clamping jaw 170 is clamped, the unqualified battery cell is clamped, and then the unqualified battery cell is moved to the second tray 130. At this time, the clamping jaw 170 can be loosened to place the unqualified battery cell into the second tray 130. Exemplarily, the second driving member 160 may be configured as a driving motor.

[0057] Specifically, the second driving member 160 is connected to the clamp 170 to drive the clamp 170 to clamp or release. Through the connection between the second driving member 160 and the clamp 170, precise control of the clamp 170 can be achieved, so that it can automatically clamp or release the object according to preset programs and instructions, which greatly improves the automation level of the battery cell loading and unloading workstation 100, reduces manual intervention, and thus improves production efficiency and product quality. Moreover, by driving the clamp 170 to clamp or release through the second driving member 160, high-precision positioning of the clamp 170 can be achieved by precisely controlling the movement of the second driving member 160, which helps to ensure that when the clamp 170 grasps or releases the object, the clamp 170 can be accurately placed in the predetermined position, thereby improving the accuracy and reliability of battery cell handling.

[0058] Please refer to Figures 1 to 8 In this embodiment, the clamping jaw 170 includes a first clamping portion 171 and a second clamping portion 172. Along the second direction Y, the first clamping portion 171 is movably disposed on the mounting frame 150 to approach or move away from the second clamping portion 172. The first direction X is perpendicular to the second direction Y. The clamping mechanism 143 also includes a first connecting portion 180 connected to the second driving member 160. The first connecting portion 180 is provided with a first sliding groove 181 inclined compared to the first direction X, and the first clamping portion 171 is provided with a first pin 171A that cooperates with the first sliding groove 181.

[0059] The clamping claw 170 includes a first clamping portion 171 and a second clamping portion 172. For example, the first clamping portion 171 and the second clamping portion 172 have a certain interval in the second direction Y. The battery cell is clamped by the first clamping portion 171 and the second clamping portion 172, thereby fixing the battery cell. The first clamping portion 171 is movably arranged on the mounting frame 150 to approach or move away from the second clamping portion 172, thereby allowing the first clamping portion 171 and the second clamping portion 172 to clamp or release the battery cell.

[0060] The clamping mechanism 143 includes a first connecting portion 180, which is connected to the second driving member 160. The second driving member 160 drives the first connecting portion 180 to change its position in the first direction X. The first connecting portion 180 is provided with a first sliding groove 181 which is inclined compared to the first direction X. The inclination angle of the first sliding groove 181 relative to the first direction X can be 30 degrees, 45 degrees or 60 degrees. The first clamping portion 171 is provided with a first pin 171A, which is fixedly connected to the first clamping portion 171. The first pin 171A can drive the first clamping portion 171 to move. The first pin 171A is plugged into the first sliding groove 181. The first pin 171A is inserted into the first sliding groove 181, and the first pin 171A can move relatively in the length direction of the first sliding groove 181.

[0061] It can be understood that since the first sliding groove 181 is inclined relative to the first direction X, when the first connecting portion 180 moves in the first direction X, it can drive the first sliding groove 181 to move in the first direction X, and the first sliding groove 181 drives the first pin 171A to move in the second direction Y. The first pin 171A is fixedly connected to the first clamping portion 171, so that the first clamping portion 171 can move in the second direction Y, which can change the position of the first clamping portion 171 in the second direction Y, so that the first clamping portion 171 is closer to the second clamping portion 172, thereby completing the clamping or loosening of the battery cell.

[0062] Illustratively, the first clamping portion 171 can be slidably connected to the mounting frame 150 via a sliding assembly, so that the position of the first clamping portion 171 in the second direction Y changes, while the position in the first direction X does not change. The embodiment of the present application does not impose any specific restrictions on the specific sliding method of the first clamping portion 171 and the mounting frame 150.

[0063] Specifically, the first connecting portion 180 is provided with a first sliding groove 181 that is inclined compared to the first direction X, and the first clamping portion 171 is provided with a first pin 171A that cooperates with the first sliding groove 181, so that the clamping jaw 170 can maintain a stable and accurate position when clamping the battery cell, avoiding damage to the battery cell or unstable clamping due to position deviation. The mobility of the first clamping portion 171 along the second direction Y enables the clamping jaw 170 to be flexibly adjusted according to the size and shape of different battery cells. This highly adaptable design enables the clamping mechanism 143 to handle more types of battery cells, thereby improving the versatility and practicality of the workstation 100.

[0064] Please refer to Figures 1 to 8 In this embodiment, along the second direction Y, the second clamping portion 172 is movably disposed on the mounting frame 150 to approach or move away from the first clamping portion 171, and the first connecting portion 180 is provided with a second sliding groove 182 inclined compared to the first direction X, and the second clamping portion 172 is provided with a second pin 172A that cooperates with the second sliding groove 182, and the inclination direction of the first sliding groove 181 is different from the inclination direction of the second sliding groove 182.

[0065] The clamping claw 170 includes a first clamping portion 171 and a second clamping portion 172. For example, the first clamping portion 171 and the second clamping portion 172 have a certain interval in the second direction Y. The battery cell is clamped by the first clamping portion 171 and the second clamping portion 172, thereby fixing the battery cell. The second clamping portion 172 is movably arranged on the mounting frame 150 to approach or move away from the first clamping portion 171, thereby allowing the first clamping portion 171 and the second clamping portion 172 to clamp or release the battery cell.

[0066] The clamping mechanism 143 includes a first connecting portion 180, which is connected to the second driving member 160. The second driving member 160 drives the first connecting portion 180 to change its position in the first direction X. The first connecting portion 180 is provided with a second sliding groove 182 which is inclined compared to the first direction X. The inclination angle of the second sliding groove 182 relative to the first direction X can be 30 degrees, 45 degrees or 60 degrees. The second sliding groove 182 can be symmetrically arranged with the first sliding groove 181. The second clamping portion 172 is provided with a second pin 172A. The second pin 172A is fixedly connected to the second clamping portion 172. The second pin 172A can drive the second clamping portion 172 to move. The second pin 172A is plugged into the second sliding groove 182. The second pin 172A is inserted into the second sliding groove 182, and the second pin 172A can move relatively in the length direction of the second sliding groove 182.

[0067] It can be understood that since the second sliding groove 182 is inclined relative to the first direction X, when the first connecting portion 180 moves in the first direction X, it can drive the second sliding groove 182 to move in the first direction X, and the second sliding groove 182 drives the second pin 172A to move in the second direction Y. The second pin 172A is fixedly connected to the second clamping portion 172, so that the second clamping portion 172 can move in the second direction Y, which can change the position of the second clamping portion 172 in the second direction Y, so that the second clamping portion 172 is closer to the first clamping portion 171, thereby completing the clamping or loosening of the battery cell.

[0068] Illustratively, the second clamping portion 172 can be slidably connected to the mounting frame 150 via a sliding assembly, so that the position of the second clamping portion 172 in the second direction Y changes, while the position in the first direction X does not change. The embodiment of the present application does not impose any specific restrictions on the specific sliding method of the second clamping portion 172 and the mounting frame 150.

[0069] Specifically, the second connecting portion is provided with a second sliding groove 182 inclined relative to the first direction X, and the second clamping portion 172 is provided with a second pin 172A cooperating with the second sliding groove 182, so that the clamping jaw 170 can maintain a stable and accurate position when clamping the battery cell, thereby avoiding damage to the battery cell or unstable clamping due to position deviation. The mobility of the second clamping portion 172 along the second direction Y enables the clamping jaw 170 to be flexibly adjusted according to the size and shape of different battery cells. This highly adaptable design enables the clamping mechanism 143 to handle more types of battery cells, thereby improving the versatility and practicality of the workstation 100.

[0070] Please refer to Figures 1 to 8 In this embodiment, the workstation 100 further includes a feeding track set 190 , and the first tray 120 is slidably disposed on the feeding track set 190 .

[0071] Exemplarily, the feeding track group 190 is actually also a part of the production line. The first tray 120 can be slidably disposed on the feeding track group 190, that is, the first tray 120 can be relatively displaced with the feeding track group 190. The feeding track group 190 can be disposed below the battery cell gripper 140. The first tray 120 slides to the bottom of the battery cell gripper 140 through the feeding track group 190, and then the first driving member 141 drives the battery cell gripper 140 to move in the first direction X, so that the clamping mechanism 143 of the battery cell gripper 140 moves to the battery cell, and then the first clamping portion 171 and the second clamping portion 172 are used to grab the battery cell.

[0072] The workstation 100 also includes a feeding track group 190, and the first tray 120 can be slidably disposed on the feeding track group 190, so that the battery cells on the first tray 120 can be transported to the bottom of the battery cell gripper 140. The battery cell gripper 140 can clamp out unqualified battery cells more quickly and add qualified battery cells to the first tray 120, thereby improving the work efficiency of the battery cell loading and unloading workstation 100.

[0073] Please refer to Figures 1 to 8 In this embodiment, the second tray 130 includes an upper line area 131 and a lower line area 132. The upper line area 131 and the lower line area 132 are located on the same side of the feeding track group 190. The upper line area 131 is closer to the feeding track group 190 than the lower line area 132. The upper line area 131 is suitable for storing qualified battery cells, and the lower line area 132 is used to store unqualified battery cells.

[0074] The second tray 130 includes an upper line area 131 and a lower line area 132 , both of which are located on the same side of the feeding track group 190 . The upper line area 131 is used to store qualified battery cells, and the lower line area 132 is used to store unqualified battery cells. In this way, the battery cell gripper 140 can clamp the qualified battery cells and the unqualified battery cells of the first tray 120 at the same time. For example, the battery cell gripper 140 has multiple claws, and the battery cell gripper 140 can clamp multiple battery cells at a time, and the multiple battery cells include qualified battery cells and unqualified battery cells. After the battery cell gripper 140 grabs the multiple battery cells in the first tray 120, the qualified battery cells can be placed in the upper line area 131 and the unqualified battery cells can be placed in the lower line area 132 in one working stroke. Compared with placing the upper line area 131 and the lower line area 132 on both sides of the feeding track group 190, this can reduce the movement distance of the battery cell gripper 140 and improve the working efficiency of the battery cell loading and unloading workstation 100.

[0075] The upper line area 131 is closer to the feeding track group 190 than the lower line area 132, that is, the lower line area 132 is farther away from the feeding track group 190. It can be understood that after the battery cell gripper 140 clamps the unqualified battery cells of the first tray 120, the unqualified battery cells are transferred to the lower line area 132. At this time, the battery cell gripper 140 needs to clamp the same number of qualified battery cells and transfer them to the first tray 120. In this way, the battery cell gripper 140 can clamp the same number of qualified battery cells on the return journey and then transfer them to the first tray 120. This reduces the moving distance of the battery cell gripper 140 and improves the operating efficiency of the battery cell loading and unloading workstation 100.

[0076] Please refer to Figures 1 to 8 In the embodiment of the present application, the upper line area 131 includes a plurality of upper line tray slots 200, and the lower line area 132 includes a plurality of lower line tray slots 210, and the upper line tray slots 200 have a positioning structure that cooperates with the battery cells.

[0077] The upper line area 131 includes a plurality of upper line tray slots 200, which can be arranged in order in the upper line area 131 in the form of a rectangular array, and the lower line area 132 includes a plurality of lower line tray slots 210, which can be arranged in order in the form of a rectangular array in the lower line area 132. Both the upper line tray slot 200 and the lower line tray slot 210 have openings, and the battery cells enter the slots from the openings, thereby completing the placement of the battery cells. The upper line tray slot 200 has a positioning structure that cooperates with the battery cells, that is, after the battery cells are placed in the upper line tray slot 200, the battery cells can be stably fixed in the upper line tray slot 200.

[0078] Exemplarily, the positioning structure may be a raised positioning point or a snap-fit ​​structure in the upper line tray slot 200 .

[0079] Specifically, the on-line tray slot 200 has a positioning structure that cooperates with the battery cell, which can ensure that the battery cell remains stationary in the correct position and posture in the tray slot of the on-line area 131, so that the battery cell maintains the correct position and posture during the loading process, thereby improving the operating accuracy of the battery cell loading and unloading workstation 100.

[0080] Please refer to Figures 1 to 8 In the present embodiment, the positioning structure is constructed as a step portion 220 arranged at the bottom of the upper line tray slot 200. The upper line tray slot 200 includes a first section 221 and a second section 222. The first section 221 is closer to the opening of the upper line tray slot 200 than the second section 222. The cross-sectional area of ​​the first section 221 is greater than the cross-sectional area of ​​the second section 222 to form the step portion 220.

[0081] The positioning structure is a step portion 220 at the bottom of the upper line tray slot 200. The upper line tray slot 200 includes a first section 221 and a second section 222. The first section 221 and the second section 222 are sequentially arranged along the first direction X. The first section 221 is closer to the opening of the upper line tray slot 200 than the second end. That is, the first section 221 is arranged above the second section 222. The cross-sectional area of ​​the first section 221 is greater than the cross-sectional area of ​​the second section 222 to form the step portion 220. When the battery cell is placed in the upper line tray slot 200, the battery cell will first enter the first section 221 and then enter the second section 222 from the first section 221. The cross-sectional areas of the first section 221 and the second section 222 are both greater than the cross-sectional area of ​​the battery cell.

[0082] The cross-sectional area of ​​the first section 221 is larger than the cross-sectional area of ​​the second section 222, so that when the cell gripper 140 clamps the cell to the online tray slot 200, it can clamp the cell to the online tray slot 200 relatively smoothly without the need for very high precision calibration. When the cell is transported to the online tray slot 200, the position of the cell can be adjusted so that the cell enters the second section 222, and the cell is more accurately fixed in the online tray slot 200, which can ensure that the cell remains in the correct position and posture in the tray slot of the online area 131, so that the cell maintains the correct position and posture during the loading process, and improves the operation accuracy of the cell loading and unloading workstation 100. Moreover, the simple structure of the online tray slot 200 can be made simpler by positioning the cell with the cross-sectional area of ​​the first section 221 being larger than the cross-sectional area of ​​the second section 222, which facilitates the maintenance of the online tray slot 200.

[0083] Please refer to Figures 1 to 8 In this embodiment, the workstation 100 also includes a sliding mechanism 230, which has a third track group 240 and a fourth track group 250. In the vertical direction, the third track group 240 and the fourth track group 250 are arranged at intervals and extend in the same direction. The second tray 130 can be slidably arranged on the third track group 240. The workstation 100 also includes a third tray 260, which can be slidably arranged on the fourth track group 250. The position of the third tray 260 in the vertical direction is adjustable.

[0084] The sliding mechanism 230 includes a third track group 240 and a fourth track group 250. Along the vertical direction, which is actually the first direction X, the third track group 240 and the fourth track group 250 are arranged at intervals, and the third track group 240 is arranged above the fourth track group 250. The second tray 130 is slidably arranged on the third track group 240, that is, the second track can move relative to the third track. The workstation 100 also includes a third tray 260, which is slidably arranged on the fourth track group 250, and the third tray 260 and the fourth track group 250 can move relative to each other. The third track group 240 and the fourth track group 250 have the same extension direction, that is, along the extension direction of the third track group 240 or the fourth track group 250, the second tray 130 and the third tray 260 have the same movement direction.

[0085] The position of the third tray 260 in the vertical direction is adjustable, which means that the position of the third tray 260 can be changed in the first direction X. Since the second tray 130 and the third tray 260 are in different positions in the first direction X, when the second tray 130 is full of unqualified cells, the second tray 130 is moved to its original position, the third tray 260 is first moved to directly below the second tray 130, and then the third tray 260 is moved along the first direction X to the position of the second tray 130.

[0086] Specifically, the third tray 260 can be slidably disposed on the fourth rail group 250, and the position of the third tray 260 in the vertical direction is adjustable, so that the battery cell loading and unloading workstation 100 can work continuously and without intervals, ensuring the connection between battery cell loading and unloading, and improving the operation efficiency of the battery cell loading and unloading workstation 100.

[0087] Please refer to Figures 1 to 8 In this embodiment, the sliding mechanism 230 also includes a sliding base plate 270 and a third driving member 280. The sliding base plate 270 is slidably disposed on the fourth track set 250. The third driving member 280 is disposed on the sliding base plate 270. The driving end 141A of the third driving member 280 is connected to the third tray 260.

[0088] The sliding mechanism 230 also includes a sliding base plate 270, which is arranged on the fourth track set 250, and the sliding base plate 270 can be relatively displaced on the fourth track set 250. The sliding mechanism 230 also includes a third driving member 280, which is arranged on the sliding base plate 270. It can be understood that when the sliding base plate is relatively displaced on the fourth track set 250, the third driving member 280 will move with the sliding base plate 270. The driving end 141A of the third driving member 280 is connected to the third tray 260, and the third tray 260 can be changed in the vertical direction by driving the third driving member 280. Exemplarily, the third driving member 280 can be set as a driving motor.

[0089] Specifically, the driving end 141A of the third driving member 280 is connected to the third tray 260, and the third tray 260 can respond to the operation instruction quickly, reduce the waiting time during the movement of the tray, and improve the operation efficiency of the battery loading and unloading workstation 100. Moreover, the third driving member 280 can continuously and stably provide power output, ensure the stability and continuity of the third tray 260 during the movement, and reduce the probability of failure of the battery loading and unloading workstation 100.
