Description

Technical Field

[0001] The present application relates to the technical field of battery cell production, and in particular to a battery cell transfer jig. Background Art

[0002] In the prior art, the circulation of battery cells is often carried by blister trays. Blister trays are usually contoured. When the production line changes the battery cell model, all blister trays need to be replaced. This way, one battery cell corresponds to one blister tray, which increases the workload and cost of the changeover. In addition, blister trays can only be transported on the logistics line and cannot be used with the battery cells in the equipment. This causes the battery cells to be transported between the pallet and the equipment many times. During the transportation process, the battery cells are at risk of being hit and scratched. Moreover, the battery cells are easily loosened after multiple transportation and positioning, which destroys the alignment of the battery cell levels. Utility Model Content

[0054] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0057] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0058] According to an embodiment of the present application, a battery cell transfer jig is provided. The structure and working principle of the battery cell transfer jig will be described in detail below in conjunction with the drawings in the specification.

[0059] According to the battery cell transport jig provided in the embodiment of the present application, the battery cell transport jig includes a load-bearing member 100, a clamping mechanism 200 and a force-applying unit 300. In the embodiment, the load-bearing member 100 includes a load-bearing body 110, and the load-bearing body 110 has a load-bearing surface 111 for placing the battery cell 500. The clamping mechanism 200 is disposed on the load-bearing member 100, and the clamping mechanism 200 includes a clamping member 210, and the clamping member 210 and the load-bearing surface 111 are disposed opposite to each other, and the clamping member 210 and the load-bearing surface 111 jointly clamp the battery cell 500. The force-applying unit 300 drives the clamping member 210 away from or close to the load-bearing surface 111.

[0060] Thus, according to the battery cell transfer jig provided in the embodiment of the present application, the clamping mechanism 200 has a clamping member 210 arranged opposite to the bearing surface 111, and the force applying unit 300 is used to drive the clamping member 210 away from or close to the bearing surface 111, so that the clamping member 210 can clamp the battery cell 500 together with the bearing surface 111 when it is close to the bearing surface 111, and can release the clamping of the battery cell 500 when the clamping member 210 is away from the bearing surface 111. Therefore, according to the battery cell transfer jig provided in the embodiment of the present application, the battery cell 500 can be clamped and released when the battery cell 500 is transferred, so that the battery cell transfer jig can enter the device with the battery cell 500, which avoids the situation that the battery cell 500 is transported between the tray and the device for multiple times, thereby reducing the risk of collision and scratching of the battery cell 500 during transportation.

[0061] In addition, due to the use of a method of clamping the battery cell, the battery cell transfer jig provided according to the embodiment of the present application has higher versatility, and there is no need to replace the jig when changing the battery cell model.

[0062] As an example, in an embodiment, the clamping member 210 and the bearing surface 111 can clamp the battery cell from the upper and lower sides respectively, so that there are no stoppers or other stopping components at the R corners and sides of the battery cell, which can prevent the battery cell from being damaged in the battery cell transfer jig.

[0063] In an embodiment, the carrier body 110 may be formed as a plate-like structure, for example, and the carrier surface 111 may be, for example, the upper surface of the carrier body 110. As an example, the upper surface of the carrier body 110 may be, for example, a plane. In an embodiment, the clamping member 210 may have, for example, a plate-like clamping portion, and the surface of the clamping portion facing the carrier surface 111 (in this embodiment, for example, the lower surface of the clamping portion) may be used to clamp the battery cell 500 together with the carrier surface 111. This surface of the clamping portion may also be, for example, a plane. In this way, the plane carrier surface 111 and the aforementioned surface of the clamping portion may better fit the outer surface of the battery cell 500, thereby ensuring the stability of the battery cell 500 being clamped.

[0064] In an embodiment, as mentioned in the above description, the clamping member 210 and the bearing surface 111 may be opposite to each other in the vertical direction, for example. That is, the movement of the clamping member 210 toward and away from the bearing surface 111 may be a lifting movement of the clamping member 210.

[0065] According to the battery cell transport jig provided in the embodiment of the present application, the carrier body 110 may also have a first positioning portion 112 and a second positioning portion 113 respectively disposed on two opposite sides of the carrier body 110. The jig may also include a positioning assembly 400, which may be spaced apart from the carrier body 110, and the first positioning portion 112 and the second positioning portion 113 may cooperate with the positioning assembly 400 to position the jig.

[0066] In the embodiment, during the actual production process of the battery cell 500, the battery cell transport jig may flow along a transport line (here, as an example, the transport line may be, for example, a conveyor belt). When the battery cell transport jig is required to stay at a position on the transport line, the positioning assembly 400 may be used in conjunction with the first positioning portion 112 and the second positioning portion 113 to achieve this.

[0067] As an example, a positioning assembly 400 may be provided outside the transfer line, corresponding to the position where the cell transfer jig needs to stop. When the cell transfer jig reaches the stop position, the cell transfer jig is positioned by the cooperation of the positioning assembly 400 with the first positioning portion 112 and the second positioning portion 113.

[0068] In an embodiment, the positioning assembly 400 may be a retractable structure, and when the retractable structure is extended, it may, for example, form an abutment fit with the first positioning portion 112 and the second positioning portion 113. Thus, the battery cell transfer jig can be positioned by utilizing the friction fit formed by the abutment. In other examples, the positioning assembly 400 is still based on a retractable structure, and the retractable structure may, for example, form a plug-in or snap-fit ​​fit (a slot and a plug-in protrusion, or a slot and a snap-fit ​​protrusion) with the first positioning portion 112 and the second positioning portion 113. In an embodiment, as Figure 1 As shown, the first positioning portion 112 and the second positioning portion 113 can both be recessed portions, and the positioning assembly 400 can extend into the recessed portions to position the fixture. Here, similar to the above description, the positioning assembly 400 can have a rod-shaped structure that can be telescopic, thereby extending into the recessed portion, and then positioning the positioning assembly 400.

[0069] In addition, in an embodiment, in an example not shown, the first positioning portion and the second positioning portion are both convex portions, such as convex portions formed on the outer edge of the carrier body, and the positioning assembly has a recessed portion corresponding to the first positioning portion and the second positioning portion (such as a recessed portion formed at the end of the above-mentioned rod-shaped structure), and each of the convex portions can extend into the corresponding recessed portion to position the fixture.

[0070] Specifically, according to the battery cell transport jig provided in the embodiment of the present application, the positioning assembly 400 may include a first positioning member 410 and a second positioning member 420 , and the first positioning member 410 and the second positioning member 420 may both be spaced apart from the carrier body 110 .

[0071] As an example, in an embodiment, the carrier body 110 may be formed substantially as a rectangular plate-like structure having a length direction and a width direction, wherein the length direction of the carrier body 110 may be, for example, the direction in which the carrier body 110 is transported along the transfer line, and the first positioning member 410 and the second positioning member 420 may be disposed on both sides of the carrier body 110 along the width direction of the carrier body 110.

[0072] Still see Figure 1 In the embodiment, the positioning assembly 400 may further include a second telescopic member 430, a third telescopic member 440, a second power member 450 and a third power member 460. The second telescopic member 430 may connect the second power member 450 and the first positioning member 410, and the second telescopic member 430 may be telescopic between the second power member 450 and the first positioning member 410, and the third telescopic member 440 may connect the third power member 460 and the second positioning member 420, and the third telescopic member 440 may be telescopic between the third power member 460 and the second positioning member 420.

[0073] On this basis, in the embodiment, the second power component 450 can drive the first positioning component 410 to cooperate with the first positioning portion 112 , and the third power component 460 can drive the second positioning component 420 to cooperate with the second positioning portion 113 .

[0074] In an embodiment, the second power component 450 may, for example, drive the first positioning component 410 to approach and move away from the carrier body 110, and the third power component 460 may, for example, drive the second positioning component 420 to approach and move away from the carrier body 110. As an example, Figure 1 As shown, the second power component 450 and the third power component 460 can be, for example, both linear drive mechanisms, and the two drive the positioning components connected to them to move in the width direction of the carrying body 110 .

[0075] More specifically, the second power member 450 and the third power member 460 may be, for example, a cylinder or an electric push rod. In an embodiment, corresponding racks may be provided for the second power member 450 and the third power member 460 to support them so that they can be maintained at a required height, that is, the height of the battery cell transfer fixture.

[0076] As an example, in an embodiment, the second power component 450 and the third power component 460 can both be relatively low-cost cylinders. At the same time, the second telescopic component 430 and the third telescopic component 440 are respectively utilized to buffer the forces applied by the corresponding cylinders. This is beneficial in ensuring that the first positioning component 410 and the second positioning component 420 are positioned with the bearing body 110 while reducing the impact of the first positioning component 410 and the second positioning component 420 on the bearing body 110.

[0077] In the embodiment, both the first positioning member 410 and the second positioning member 420 may include, for example, a rod, which may extend along the width direction of the load-bearing body 110, with one end thereof facing the load-bearing body 110, and the other end thereof connected to the respective corresponding power member via the respective corresponding telescopic member. As an example, in the embodiment, the end of the rod facing the load-bearing body 110 is used to penetrate into the corresponding positioning portion, that is, the end of the rod of the first positioning member 410 extends into the first positioning portion 112, and the end of the rod of the second positioning member 420 extends into the second positioning portion 113.

[0078] As an example, in an embodiment, the second telescopic member 430 and the third telescopic member 440 may both be formed as flexible joints, for example.

[0079] As an example, the first positioning members 410 and the second positioning members 420 may be provided in multiple groups, such as two groups, three groups, or four groups, or even more groups, and the multiple groups of the first positioning members 410 and the second positioning members 420 may be arranged at intervals along the length direction of the carrier body 110. In addition, in the length direction of the carrier body 110, the distance between the first group and the second group should be less than or equal to the length of the carrier body 110, so as to ensure that each group is matched with the carrier body 110.

[0080] In the embodiment, it should be noted that when multiple groups of the first positioning members 410 and the second positioning members 420 are provided, each first positioning member 410 is still configured with a corresponding second power member 450 and a second telescopic member 430. In addition, the bearing body 110 also has a first positioning portion 112 that cooperates with the first positioning member 410. Similarly, the second positioning member 420 is also the same. Here, as Figure 1 As shown, two groups of first positioning members 410 and second positioning members 420 may be provided, and the two groups of first positioning members 410 and second positioning members 420 are respectively provided close to both sides of the carrying body 110 in the length direction thereof to ensure that the carrying body 110 is stably positioned.

[0081] According to the battery cell transport jig provided in the embodiment of the present application, as described above, the battery cell transport jig can be configured to be transported via a transport component, and the positioning component 400 can be set on the transport component, that is, as an example, the transport component can include the above-mentioned rack for providing a setting position for the second power component 450 and the third power component 460.

[0082] In an embodiment, the first positioning member 410 may include a first rolling portion 411 for cooperating with the first positioning portion 112, and the second positioning member 420 may include a second rolling portion 421 for cooperating with the second positioning portion 113, and the first rolling portion 411 and the second rolling portion 421 can both roll along the outer side of the supporting body 110 to the first positioning portion 112 and the second positioning portion 113 respectively.

[0083] In the embodiment, the supporting body 110 can form a rolling fit with the first positioning member 410 and the second positioning member 420 through the first rolling portion 411 and the second rolling portion 421. Thus, by utilizing this rolling fit, the first rolling portion 411 and the second rolling portion 421 can respectively roll into the first positioning portion 112 and the second positioning portion 113, thereby assisting the rods where the first rolling portion 411 and the second rolling portion 421 are respectively located to correct the position of the supporting body 110 in its length direction, thereby facilitating accurate positioning of the supporting body 110.

[0084] As an example, in the embodiment, the first rolling portion 411 and the second rolling portion 421 may both be rollers with their axes arranged along the vertical direction.

[0085] According to the battery cell transport fixture provided in the embodiment of the present application, the force applying unit 300 may include a rotation module 381, a guide module 384 and a force applying module 320. The rotation module 381 may be connected to the clamping member 210. The guide module 384 has an axial direction F, and the rotation module 381 may be movably matched with the guide module 384, and the guide module 384 may be configured so that the rotation module 381 can move along the axial direction F relative to the guide module 384 and can rotate relative to the guide module 384. The force applying module 320 may be connected to the rotation module 381, and the force applying module 320 drives the rotation module 381 to move along the axial direction F.

[0086] In an embodiment, the clamping member 210 may be away from or close to the bearing surface 111 along the axial direction F. That is to say, as an example, the axial direction F may be, for example, a vertical direction.

[0087] Thus, according to the battery cell transport jig provided by the embodiment of the present application, when the force application module 320 drives the rotating module 381 to move along the axial direction F, the rotating module 381, under the guidance of the guide module 384, not only moves along the axial direction F of the guide module 384, but also rotates relative to the guide module 384. This allows the clamping member 210 to have both movement close to and away from the bearing surface 111, and rotational movement offset relative to a position on the bearing surface 111. Thus, when the clamping member 210 releases the clamping of the battery cell 500, it also leaves the outside of the battery cell 500 due to the aforementioned rotational movement, making it easier to remove the battery cell 500 from the battery cell transport jig.

[0088] Specifically, according to the battery cell transport jig provided in the embodiment of the present application, the rotating module 381 may include a rotating member 382 and a connecting member 310. In the embodiment, the clamping member 210 may be connected to the rotating member 382. The connecting member 310 may have an inclined portion 311, and the connecting member 310 is rotatably connected to the rotating member 382, ​​and the inclined portion 311 may have a first position 312 close to the guide module 384 in the axial direction F and a second position 313 away from the guide module 384 in the axial direction F.

[0089] In the embodiment, the force module 320 can move along a direction perpendicular to the axial direction F to move from the first position 312 to the second position 313 along the inclined portion 311, so that the rotating member 382 and the connecting member 310 move along the axial direction F. In this way, when the aforementioned movement process occurs, since the first position 312 is closer to the guide module 384 (i.e., the first position 312 is higher), as the force module 320 moves from the first position 312 to the second position 313, the connecting member 310 will be pushed toward the guide module 384 by the force module 320, that is, the connecting member 310 is lifted by the force module 320, and the rotating member 382 connected to the connecting member 310 is also lifted together.

[0090] In the embodiment, the rotating member 382 is guided by the guide module 384 after being lifted, thereby rotating. Since the rotating member 382 and the connecting member 310 are rotatably connected, the rotating member 382 also rotates relative to the connecting member 310 without driving the connecting member 310 to rotate.

[0091] In an embodiment, the connection member 310 may be formed into a block shape, for example, and the inclined portion 311 may be the upper side of a groove opened on the connection member 310, which may include a planar first position 312 and a second position 313 and an inclined surface extending therebetween.

[0097] In the embodiment, the first power member 360 can refer to the second power member 450 and the third power member 460 as described above, the first telescopic member 370 can refer to the second telescopic member 430 and the third telescopic member 440 as described above, and the driving member 350 can be, for example, a rod. No further description is given here, that is, the driving member 350 is used to move along the width direction of the bearing body 110 to abut against the force application body 321, so that the force application module 320 moves along the width direction of the bearing body 110.

[0098] In an embodiment, the driving member 350 is disposed on a transport assembly, for example, on the frame described above, that is, a frame corresponding to the first power member 360 , the first telescopic member 370 and the driving member 350 .

[0099] In an embodiment, the force-applying portion 322 may be configured as a rolling structure capable of rolling along the inclined portion 311, thereby reducing the friction between the inclined portion 311 and the force-applying portion 322. Here, the rolling structure may also be a roller, which may be mounted to the rod of the force-applying portion 322, for example, by means of screws and bearings. In some examples, the rolling structure may be a bearing directly. In addition, in an embodiment, the inclined portion 311 may be configured as a slide groove provided on the connecting member 310, and the roller may be accommodated in the slide groove, thereby sliding along the inner wall of the slide groove.

[0100] According to the battery cell transfer jig provided in the embodiment of the present application, the guide module 384 may include a guide member 385, the rotating module 381 may include a rotating member 382, ​​the guide member 385 may be sleeved on the rotating member 382, ​​the first of the rotating member 382 and the guide member 385 may have a guide portion 386, the guide portion 386 has a spiral segment 387, the second of the rotating member 382 and the guide member 385 may have a guide protrusion 383, and the guide protrusion 383 cooperates with the guide portion 386.

[0101] In an embodiment, relative movement between any one of the first and second along the axial direction F may cause the guide protrusion 383 to move along the guide portion 386 , so that the rotating member 382 rotates when the guide protrusion 383 passes through the spiral section 387 .

[0102] As an example, in an embodiment, the rotating member 382 may include a shaft member, and the guide member 385 may be, for example, a guide sleeve, which may be sleeved on the outside of the shaft member. In an embodiment, the guide member 385 may be, for example, fixed on a frame member 330 to be described later, which will be described in the subsequent description.

[0103] In an embodiment, the guide portion 386 may be formed on the guide sleeve, for example, and the guide portion 386 may be a hole portion penetrating the guide sleeve, and the hole portion extends along a predetermined trajectory. Specifically, the guide portion 386 has a spiral section, that is, a spiral section coaxial with the axis of the guide sleeve, and the guide portion 386 may also have a first axial F section and a second axial F section (both of which are strip-shaped holes extending along the axial F) connected at both ends of the spiral section.

[0104] In an embodiment, the guide protrusion 383 can be provided on the outside of the shaft member of the rotating member 382. The guide protrusion 383 can be, for example, a guide pin. In this way, when the shaft member rises, the guide pin now moves in the first axial F section located below, and during this process the shaft member moves (rises) along the axial F section. When the shaft member continues to rise, the guide pin moves from the upper part of the first axial F section to the lower part of the spiral section. Due to the guidance of the spiral section, the guide pin both rises and rotates until it reaches the upper part of the spiral section, and the movement state of the shaft member is synchronized with the guide pin. When the shaft member continues to rise, the guide pin rises along the second axial F section. This series of movement processes is vice versa.

[0105] As an example, in the embodiment, the guide sleeve may have two guide portions 386, and correspondingly, the outer side of the shaft member may also be provided with guide protrusions 383 respectively guided by the two guide portions 386. Here, in the embodiment, the two guide protrusions 383 may differ by 180° in the circumferential direction of the shaft member.

[0106] According to the battery cell transport jig provided in the embodiment of the present application, the force applying unit 300 may further include a frame member 330 and a reset member 340. The guide module 384 may be disposed on the frame member 330, and the frame member 330 may be connected to the carrier body 110. The reset member 340 may be disposed between a portion of the rotating module 381 and the frame member 330. The force applying module 320 drives the rotating module 381 to move along the axial direction F, so that the reset member 340 stores elastic potential energy.

[0107] In this way, when the rotating module 381 rises, that is, when it approaches the frame member 330, the reset member 340 stores elastic potential energy. When the force application module 320 no longer drives the rotating module 381, the elastic potential energy stored in the reset member 340 is released, driving the rotating module 381 to descend and reset. As an example, in an embodiment, the reset member 340 can be, for example, a coil spring, which can be sleeved on the outer side of the shaft member of the rotating member 382, ​​and the lower end of the shaft member can be formed with a step, the lower end of the coil spring abuts against the step, and the upper end abuts against the frame member 330.

[0108] In addition, in an embodiment, the frame member 330 may include two plates opposite to each other in the length direction of the carrier body 110 and a third plate connected to the upper ends of the two plates. The clamping member 210 may also include a connecting rod connecting the plate-shaped clamping portion and connected to the upper end of the shaft member passing through the third plate.

[0109] In an embodiment, the guide sleeve may have a step structure, and the step structure may be connected to the upper end surface of the third plate of the frame member 330, and the remaining portion of the guide sleeve may be inserted into the third plate.

[0110] According to the battery cell transfer jig provided in the embodiment of the present application, the carrier body 110 has a mounting portion 114 disposed on the edge of the carrier body 110, and a portion of the clamping mechanism 200 may be connected to the mounting portion 114. Specifically, the above-mentioned frame member 330 may be connected to the mounting portion 114. In an embodiment, as an example, the mounting portion 114 may be a notch portion disposed on one long side of the carrier body 110. On the one hand, the notch portion reduces the weight of the carrier body 110, thereby achieving a weight reduction effect. On the other hand, a portion of the frame member 330 is disposed in the notch portion, making the battery cell transfer jig more compact in structure.

[0111] As an example, in an embodiment, Figure 2 As shown, the notch portion may include two inner portions opposite to each other in the length direction of the carrier body 110 , and the two inner portions may be respectively connected to two opposite plates of the frame member 330 , for example, detachably connected by fasteners (such as screws).

[0112] In an embodiment, the bearing member 100 may further include a plurality of lifting and positioning portions 120 evenly distributed on the side of the bearing body 110 facing away from the bearing surface 111, and each lifting and positioning portion 120 may have a lifting recess. Figure 2 As shown, the lifting positioning portion 120 may be, for example, a lifting bushing, on which the aforementioned lifting recess may be provided. In an embodiment, a recess may be pre-formed on the side of the bearing body 110 facing away from the bearing surface 111, and then the lifting bushing is inserted into the recess. Figure 2As shown, the number of the lifting bushings may be four, and the four lifting bushings may be respectively disposed at the four corners of the bearing body 110 .

[0113] In an embodiment, the battery cell transport jig can be lifted by a lifting mechanism to be separated from the transport assembly, and the lifting mechanism includes a plurality of lifting parts corresponding to the plurality of lifting positioning parts 120 (according to the above example, the number of lifting parts can also be 4 accordingly), and each lifting part is used to be embedded in the corresponding lifting recess. As an example, the lifting mechanism can include a lifting cylinder and a frame connected to the piston rod of the lifting cylinder, and the lifting part can be, for example, a rod-shaped structure, and the lifting part can extend in the vertical direction and be connected to the aforementioned frame.

[0114] In an embodiment, the bearing member 100 may further include a first grasping positioning portion 131 and a second grasping positioning portion 132 respectively disposed on two opposite sides of the bearing body 110 , and the first grasping positioning portion 131 and the second grasping positioning portion 132 may both have a grasping recess.

In this way, the battery cell transport jig provided in the embodiment of the present application allows the gripping mechanism to grip the battery cell transport jig, thereby separating it from the transport component, that is, detaching it from the transport line.

[0116] In an embodiment, similar to the lifting mechanism, the gripping mechanism may include a gripping protrusion corresponding to each gripping recess, and each gripping protrusion is used to be embedded in the corresponding gripping recess. In an embodiment, as an example, the gripping mechanism may be, for example, a manipulator, and the gripping protrusion may also be, for example, a rod-shaped structure.

[0117] From the above content, it can be known that the clamping mechanism 200 is installed on the carrying body 110, and completes the clamping and loosening of the battery cell 500 during the transportation process. After reaching the preset position, the lifting mechanism lifts up the entire battery cell transportation jig, and the grasping mechanism grasps the corresponding grasping recess to send the entire battery cell transportation jig into the welding mechanism of the lower workstation for welding. During the whole process, the battery cell 500 is in a clamped state and will not loosen, and the battery cell 500 does not need to contact the grasping component, avoiding the risk of the battery cell being scratched.

[0118] In an embodiment, Figure 2As shown, the first gripping and positioning portion 131 and the second gripping and positioning portion 132 can be respectively arranged on both sides of the load-bearing body 110 in the length direction. In an embodiment, the number of the first gripping portions can be, for example, two, and the number of the second gripping portions can also be, for example, two. The two first gripping portions are arranged near two corners of the load-bearing body 110, and the two second gripping portions are arranged near the other two corners of the load-bearing body 110.

[0119] In addition, if Figure 2 As shown, a plurality of weight-reducing recesses 115 may be provided at the bottom of the carrier body 110 to reduce the weight of the carrier body.

[0120] In addition, in the embodiment, the bearing member 100 may further include a pad member 140 disposed on the bearing surface 111, and the pad member 140 is used to bear the battery cell 500, thereby protecting the battery cell 500. As an example, the pad member 140 may be, for example, in the shape of a rectangular parallelepiped, and the plane with the largest area is used to bear the battery cell 500. As an example, in the embodiment, the pad member may be formed of, for example, a flexible material such as rubber.

[0121] According to the battery cell transfer jig provided in the embodiment of the present application, the size of the load-bearing member 100 can be designed according to the compatible range of the production line of the battery cell 500. In an embodiment, the cushion member 140 and the clamping member 210 in the battery cell transfer jig may not be rubber-coated, and the rubber coating hardness of the two may be: Shore hardness 20 to 30°. According to the battery cell transfer jig provided in the embodiment of the present application, all parts in contact with the battery cell 500 may adopt a non-metallic design (such as the aforementioned rubber coating design), and the contact surface with the battery cell 500 may be rounded R2 or more. Metal parts (such as parts that do not contact the battery cell) are assembled by slots with a matching accuracy of 0.1mm.

[0122] The following will describe the operation process of the battery cell transfer jig provided according to an embodiment of the present application.

[0123] The driving member 350 provides power and abuts against the force-applying body 321, causing the force-applying body 321 to move horizontally, causing the connecting member 310 to rise, driving the rotating member 382 to rise, so that the rotating member 382 is guided by the guide member 385 to rotate while rising, thereby causing the clamping member 210 connected to the rotating member 382 to rise and rotate, thereby leaving the top of the cushion member 140, and at this time placing the battery cell 500 on the cushion member 140. After the battery cell 500 is placed, the driving member 350 is removed, and the clamping member 210 is reset to press down and clamp the battery cell 500.

[0124] When the cell transport jig transports the cell 500 to the designated position, the positioning assembly 400 positions the cell transport jig at the designated position, the first positioning member 410 extends into the corresponding first positioning portion 112 on the carrier body 110, and the second positioning member 420 extends into the corresponding second positioning portion 113 on the carrier body 110, to position the cell transport jig. After the positioning is completed, the positioning assembly 400 can be released to release the positioning of the cell transport jig, and the cell transport jig and the cell 500 can be moved to the next station together by the robot.

[0125] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. All equivalent structural changes made by using the contents of the present application specification and drawings under the innovative concept of the present application, or directly / indirectly applied in other related technical fields are included in the protection scope of the present application.
