Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a clamping device and a battery production line. Background Technology

[0002] In the battery cell manufacturing industry, electrolyte needs to be injected into the battery cells. Sufficient electrolyte can ensure the performance and lifespan of the battery cells. After the electrolyte injection is completed, a robotic arm is needed to pick up the battery cells and unload them.

[0003] When using the robotic arm in the related technology, electrolyte can easily spray out from the injection port, affecting the appearance and performance of the battery cell. Utility Model Content

[0004] In view of the above problems, this application provides a clamping device and a battery production line, which can solve the problem that electrolyte is easily sprayed out from the injection port when the robot is in use.

[0005] To address the aforementioned technical problems, in a first aspect, this application proposes a clamping device, comprising:

[0006] Fixing plate;

[0007] At least one pair of grippers, the grippers being disposed on the fixing plate, and the pair of grippers being able to move closer to or further away from each other;

[0008] A sealing element is disposed on the fixing plate, and the sealing element is configured to block the liquid injection port on the battery cell when the battery cell is held by a pair of grippers.

[0009] In the technical solution of this application embodiment, when the gripper holds the battery cell, the sealing member can seal the liquid injection port on the battery cell, so that the electrolyte will not spray out due to the deformation of the battery cell. During the movement of the overall device in gripping the battery cell, the electrolyte will not overflow from the liquid injection port due to the shaking of the battery cell. This effectively solves the appearance and performance problems caused by electrolyte contamination during the battery cell manufacturing process.

[0010] In some embodiments, the sealing member includes a connecting plate and a plug, the connecting plate being disposed on the fixing plate and located between a pair of the clamps, and the plug being disposed on the side of the connecting plate facing the battery cell.

[0011] In this way, when a pair of jaws hold the battery cell, the plug on the connecting plate between the jaws can seal the electrolyte injection port on the battery cell, so that the electrolyte will not spray out due to the deformation of the battery cell.

[0012] In some embodiments, the clamping device further includes a connecting block disposed on the side of the fixing plate facing the battery cell;

[0013] The connecting plate includes a base plate and side plates disposed at both ends of the base plate. The plug is disposed on the side of the base plate facing the battery cell. The side plates are disposed on the connecting block and can move relative to the connecting block in a first direction, wherein the first direction is the axial direction of the injection port.

[0014] In this way, by adjusting the position of the side plate relative to the connecting block along the first direction, the position of the plug on the bottom plate relative to the cell's liquid injection port can be adjusted synchronously so that the plug can be adapted to liquid injection ports of different sizes.

[0015] In some embodiments, the clamping device further includes a fastener, a first elongated hole is provided on the side plate, and a second elongated hole is provided on the connecting block, wherein both the first elongated hole and the second elongated hole extend along the first direction;

[0016] The fastener passes through the first elongated hole and the second elongated hole and connects to the connecting block. In this way, by adjusting the relative position of the fastener in the first elongated hole and the second elongated hole, the position of the side plate relative to the connecting block along the first direction can be adjusted, and thus the position of the plug on the bottom plate relative to the cell filling port can be adjusted synchronously.

[0017] In some embodiments, the clamping device further includes a first drive member and a movable plate;

[0018] The movable plate is disposed between the fixed plate and the gripper, the side plate is connected to the movable plate, the first driving member is fixed to the fixed plate, the first driving member passes through the fixed plate and is connected to the movable plate, and is configured to drive the movable plate to move along the first direction.

[0019] In this way, by driving the moving plate along the first direction through the first driving component, the position of the side plate in the first direction can be adjusted synchronously, and thus the position of the plug on the bottom plate relative to the cell liquid injection port can be adjusted.

[0020] In some embodiments, the clamping device further includes a guide plate and a second driving member;

[0021] The guide plate is disposed between the moving plate and the gripper, and the second driving member is disposed on the guide plate and connected to the gripper for driving the gripper to move along a second direction, wherein the second direction intersects with the first direction.

[0022] In this way, the second driving component can easily move the grippers closer or further apart to clamp the battery cell.

[0023] In some embodiments, the plug includes a connecting rod and a plug, the plug being disposed at one end of the connecting rod facing the battery cell, a groove being formed between the connecting rod and the plug, and the plug being connected to the base plate through the groove.

[0024] In this way, the plug can be easily connected to the base plate by the cooperation of the slot and the base plate.

[0025] In some embodiments, the surface of the plug is provided with a corrosion-resistant layer. This way, when the plug is placed over the injection port, the corrosion-resistant layer on the plug surface prevents the electrolyte from corroding and damaging the plug.

[0026] In some embodiments, the surface of the plug is provided with a flexible layer.

[0027] In this way, when the plug is placed on the injection port, the flexible layer on the surface of the plug prevents it from colliding and damaging the injection port when it comes into contact with the injection port.

[0028] In some embodiments, the end of the plug facing the battery cell has a chamfer.

[0029] In this way, when the plug comes into contact with the injection port, it avoids the sharp edges of the plug facing the injection port from colliding with the injection port and causing damage to the injection port.

[0030] In some embodiments, the plug includes a housing, a movable rod, an elastic element, and a plug.

[0031] The outer shell is disposed on the base plate, and the interior of the outer shell is a hollow structure. The elastic element and the movable rod are both disposed inside the outer shell. The elastic element is located above the movable rod along the first direction, and the movable rod is capable of moving relative to the outer shell along the first direction.

[0032] One end of the movable rod is connected to the elastic element, and the other end extends out of the outer shell and is connected to the plug.

[0033] In this way, when the plug comes into contact with the injection port, the plug has a certain degree of elasticity under the action of the elastic element, which avoids the plug from having a hard collision with the injection port, thereby preventing damage to the injection port.

[0034] In some embodiments, the fixing plate is provided with a sliding groove that extends along a second direction, and the connecting block is slidably connected to the fixing plate through the sliding groove.

[0035] This allows for easy adjustment of the position of the connecting block in the second direction, thereby facilitating synchronous adjustment of the position of the plug on the connecting plate in the second direction.

[0036] In some embodiments, a flexible pad is provided on the side of the gripper facing the battery cell.

[0037] In this way, when the gripper holds the battery cell, the gripper contacts the side of the battery cell through the flexible pad, avoiding damage to the side of the battery cell.

[0038] In some embodiments, the clamping device further includes a robotic arm connected to the fixed plate. This allows the robotic arm to move the grippers.

[0039] Secondly, this application proposes a battery production line, including a clamping device as described in any one of the embodiments of this application.

[0058] The following is a detailed description of this application.

[0059] In the battery cell manufacturing industry, electrolyte needs to be injected into the battery cells. Sufficient electrolyte can ensure the performance and lifespan of the battery cells. After the electrolyte injection is completed, a robotic arm is needed to pick up the battery cells and unload them.

[0060] When the robotic arm in the relevant technology is in use, the slight deformation of the battery cell and the insufficient internal space of the battery cell will cause the electrolyte to spray out from the injection port, thereby causing electrolyte contamination of the battery cell and affecting the appearance and performance of the battery cell.

[0061] Based on the above considerations, in order to solve the problem that the electrolyte is easily sprayed out from the injection port when the robot is in use, a clamping device is designed. The clamping device includes a fixed plate, a sealing member and at least a pair of grippers. The grippers are disposed on the fixed plate and the pair of grippers can move closer or further apart from each other. The sealing member is disposed on the fixed plate. Under the condition that the pair of grippers hold the battery cell, the sealing member is configured to block the injection port on the battery cell.

[0062] In the technical solution of this application embodiment, when the gripper holds the battery cell, the sealing member can seal the liquid injection port on the battery cell, so that the electrolyte will not spray out due to the deformation of the battery cell. During the movement of the overall device in gripping the battery cell, the electrolyte will not overflow from the liquid injection port due to the shaking of the battery cell. This effectively solves the appearance and performance problems caused by electrolyte contamination during the battery cell manufacturing process.

[0063] According to some embodiments of this application, Figure 1 This is a schematic diagram of the clamping device in this application. Figure 2 This is a schematic diagram of the clamping device in this application from another perspective. Figure 1 and combined Figure 2 As shown, this application proposes a clamping device, which includes a fixing plate 10, at least a pair of clamping claws 11 and a sealing member 12. The clamping claws 11 are disposed on the fixing plate 10, and the pair of clamping claws 11 can move closer to or further away from each other. The sealing member 12 is disposed on the fixing plate 10. Under the condition that the pair of clamping claws 11 clamp the battery cell, the sealing member 12 is configured to block the liquid injection port on the battery cell.

[0064] This embodiment may include two or four grippers 11, but is not limited here.

[0065] In this embodiment, the gripper 11 can be controlled by an electric telescopic rod, cylinder, etc., so that the two grippers 11 move closer or further apart. The specific method can be determined according to the actual situation, and this embodiment does not limit this.

[0066] In this embodiment, the sealing component 12 can be a rubber block, silicone block, resin block, etc.

[0067] In this embodiment, the gripper 11 can be connected to the fixed plate 10 via a slider, cylinder, electric telescopic rod, etc., and the sealing member 12 can be connected to the fixed plate 10 via bolts. During use, when the gripper 11 holds the battery cell, the sealing member 12 can seal the electrolyte injection port on the battery cell. This prevents electrolyte from spraying out due to the deformation of the battery cell, and the entire device will not cause electrolyte to overflow from the injection port due to battery cell shaking during the gripping process. This effectively solves the appearance and performance problems caused by electrolyte contamination during battery cell manufacturing.

[0068] According to some embodiments of this application, such as Figure 1 As shown, the sealing component 12 includes a connecting plate 121 and a plug 122. The connecting plate 121 is disposed on the fixing plate 10 and is located between a pair of clamps 11. The plug 122 is disposed on the side of the connecting plate 121 facing the battery cell.

[0069] like Figure 3As shown, the connecting plate 121 in this embodiment has an overall U-shaped structure. The connecting plate 121 can be connected to the fixing plate 10 by bolts or snap-fit. The plug 122 can also be connected to the connecting plate 121 by bolts or snap-fit. The plug 122 is installed on the side of the connecting plate 121 facing the battery cell.

[0070] When in use, when the jaws 11 hold the battery cell, the plug 122 on the connecting plate 121 located between the pair of jaws 11 can seal the electrolyte injection port on the battery cell, so that the electrolyte will not spray out due to the deformation of the battery cell.

[0071] According to some embodiments of this application, such as Figure 1 As shown, the clamping device also includes a connecting block 13, which is disposed on the side of the fixing plate 10 facing the battery cell; meanwhile, refer to Figure 3 As shown, the connecting plate 121 includes a base plate 1211 and side plates 1212 disposed at both ends of the base plate 1211. The plug 122 is disposed on the side of the base plate 1211 facing the battery cell. The side plates 1212 are disposed on the connecting block 13 and can move relative to the connecting block 13 in a first direction, wherein the first direction is the axial direction of the liquid injection port.

[0072] The first direction in this embodiment is as follows: Figure 1 The X-axis direction in the diagram.

[0073] In this embodiment, the connecting block 13 can be mounted on the bottom surface of the fixing plate 10 using bolts. (See reference...) Figure 3 As shown, the base plate 1211 and the side plate 1212 are connected to form a U-shaped structure. The side plate 1212 can be connected to the connecting block 13 by bolts or sliders. At the same time, the side plate 1212 can move relative to the connecting block 13 along the X-axis direction, and the plug 122 can be snapped onto the base plate 1211.

[0074] In this way, by adjusting the position of the side plate 1212 relative to the connecting block 13 along the X-axis, the position of the plug 122 on the bottom plate 1211 in the X-axis direction can be adjusted simultaneously, thereby adjusting the position of the plug 122 and the corresponding cell liquid injection port so that the plug 122 can be adapted to liquid injection ports of different sizes.

[0075] According to some embodiments of this application, the clamping device further includes fasteners (not shown in the figures), such as... Figure 3 and combined Figure 2 As shown, a first elongated hole 12121 is provided on the side plate 1212, and a second elongated hole 131 is provided on the connecting block 13. Both the first elongated hole 12121 and the second elongated hole 131 extend along a first direction. Fasteners pass through the first elongated hole 12121 and the second elongated hole 131 and are connected to the connecting block 13.

[0076] The first direction in this embodiment can be referred to the description above, and will not be repeated here.

[0077] In this embodiment, the fastener can be a bolt. After the bolt passes through the corresponding first elongated hole 12121 and second elongated hole 131, it is connected to the connecting block 13, thereby fixing the side plate 1212 to the connecting block 13.

[0078] By adjusting the relative positions of the fasteners in the first elongated hole 12121 and the second elongated hole 131, the position of the side plate 1212 relative to the connecting block 13 along the X-axis can be adjusted, thereby simultaneously adjusting the position of the plug 122 on the base plate 1211 relative to the cell liquid injection port.

[0079] According to some embodiments of this application, such as Figure 1 and combined Figure 2 As shown, the clamping device also includes a first driving member 14 and a movable plate 15. The movable plate 15 is disposed between the fixed plate 10 and the gripper 11. The side plate 1212 is connected to the movable plate 15. The first driving member 14 is fixed to the fixed plate 10 and passes through the fixed plate 10 to connect with the movable plate 15. It is configured to drive the movable plate 15 to move along a first direction.

[0080] In this embodiment, the first driving component 14 can be an electric telescopic rod, a cylinder, etc. The specific one can be determined according to the actual situation, and this specification does not limit it in this embodiment.

[0081] In this embodiment, the first driving member 14 can be fixed to the fixing plate 10 by bolts, as shown in the reference. Figure 2 As shown, the telescopic end of the first driving member 14 passes through the fixed plate 10 from top to bottom and connects to the movable plate 15. The gripper 11 can be connected to the bottom surface of the movable plate 15 via a slider, electric telescopic rod, etc. Meanwhile, the side plate 1212 can be connected to the movable plate 15 by bolts or snap-fit.

[0082] In use, loosen the fasteners between the side plate 1212 and the connecting block 13, and then drive the moving plate 15 to move along the X-axis direction through the first driving member 14. Since the side plate 1212 is connected to the moving plate 15, when the moving plate 15 moves up and down along the X-axis direction, it can drive the side plate 1212 to move up and down along the X-axis direction, thereby adjusting the position of the plug 122 on the bottom plate 1211 relative to the cell liquid injection port so that the plug 122 can make good contact with the liquid injection port.

[0083] According to some embodiments of this application, such as Figure 1 or Figure 2As shown, the clamping device also includes a guide plate 16 and a second driving member. The guide plate 16 is disposed between the moving plate 15 and the gripper 11. The second driving member is disposed on the guide plate 16 and connected to the gripper 11 to drive the gripper 11 to move along a second direction, wherein the second direction intersects with the first direction.

[0084] The second direction in this embodiment is as follows: Figure 1 The Y-axis direction is defined in the diagram, where the angle between the X-axis and Y-axis can be 80°, 85°, 90°, etc. For ease of explanation, the following explanation will assume that the X-axis and Y-axis are perpendicular.

[0085] The second driving component in this embodiment can be a cylinder, an electric telescopic rod, etc., and the specific one can be determined according to the actual situation. This specification does not limit this embodiment.

[0086] In this embodiment, the guide plate 16 can be fixed to the bottom surface of the movable plate 15 with bolts, and the second driving member can be fixed to the bottom surface of the guide plate 16 with bolts. At the same time, the telescopic end of the second driving member is connected to the gripper 11. In this way, the second driving member can easily drive the gripper to move closer or further apart to clamp the battery cell.

[0087] According to some embodiments of this application, such as Figure 5 and combined Figure 3 , Figure 4 As shown, the plug 122 includes a connecting rod 1221 and a plug 1222. The plug 1222 is disposed at the end of the connecting rod 1221 facing the battery cell. A groove 1223 is formed between the connecting rod 1221 and the plug 1222. The plug 122 is connected to the base plate 1211 through the groove 1223.

[0088] In this embodiment, the plug 122 can be made of rubber, silicone, or other materials, and no specific material is specified here.

[0089] refer to Figure 5 As shown, the lower end of the connecting rod 1221 along the axial direction is integrally formed with the plug 1222, and a groove 1223 is formed between the connecting rod 1221 and the plug 1222. In this way, the plug 122 can be easily connected to the base plate 1211 by engaging with the base plate 1211 through the groove 1223.

[0090] It should be noted that the structure of the plug described above is merely an example. Other alternative structures can also be used, for example, the plug may include a spring connected between the connecting rod and the plug. This application does not impose any special restrictions on the specific structure of the plug, as long as the above structure achieves the purpose of this application.

[0091] According to some embodiments of this application, the surface of the plug 1222 is provided with a corrosion-resistant layer.

[0092] The corrosion-resistant layer in this embodiment can be EPDM rubber, PTFE, polypropylene, etc., and is not limited here.

[0093] In this embodiment, a corrosion-resistant layer is provided on the surface of the plug 1222. In this way, when the plug 1222 is sealed on the injection port, the electrolyte can be prevented from corroding and damaging the plug 1222 because the surface of the plug 1222 has a corrosion-resistant layer.

[0094] According to some embodiments of this application, the surface of the plug 1222 is provided with a flexible layer.

[0095] The flexible layer in this embodiment can be a rubber layer, a silicone layer, etc., and is not limited here.

[0096] In this embodiment, a flexible layer is provided on the surface of the plug 1222. In this way, when the plug 1222 is sealed on the injection port, the flexible layer on the surface of the plug 1222 prevents the plug 1222 from colliding and damaging the injection port.

[0097] According to some embodiments of this application, such as Figure 5 As shown, the end of the plug 1222 facing the battery cell has a chamfer 12221. This prevents the sharp corner of the plug 1222 facing the injection port from colliding with the injection port and causing damage to the injection port when the plug 1222 comes into contact with it.

[0098] According to some embodiments of this application, such as Figure 6 As shown, the plug 122 includes a housing 1224, a movable rod 1225, an elastic element 1226, and a nozzle 1222. The housing 1224 is disposed on the base plate 1211 and has a hollow structure. The elastic element 1226 and the movable rod 1225 are both disposed inside the housing 1224. The elastic element 1226 is located above the movable rod 1225 along a first direction, and the movable rod 1225 can move relative to the housing 1224 along the first direction. One end of the movable rod 1225 is connected to the elastic element 1226, and the other end extends out of the housing 1224 and is connected to the nozzle 1222.

[0099] The first direction in this embodiment can be referred to the description above, and will not be repeated here.

[0100] In this embodiment, the elastic element 1226 can refer to a component that can deform under the action of external force and return to its original shape after the external force is removed. The elastic element 1226 can be elastically compressed in the X-axis direction. The elastic element 1226 can be made of metal or non-metal, such as leaf spring, coil spring, gas spring, rubber spring, etc. The specific material can be determined according to the actual situation. This embodiment of the specification does not limit this.

[0101] In this embodiment, the upper end of the elastic element 1226 is fixed inside the outer shell 1224, the lower end of the elastic element 1226 is connected to the upper end of the movable rod 1225, and the lower end of the movable rod 1225 extends out of the outer shell 1224 and is connected to the plug 1222.

[0102] When in use, when the plug 1222 comes into contact with the injection port, the plug 1222 has a certain degree of elasticity under the action of the elastic element 1226, so as to avoid the plug 1222 from having a hard collision with the injection port, thereby causing damage to the injection port.

[0103] According to some embodiments of this application, such as Figure 1 As shown, a sliding groove 101 is provided on the fixed plate 10. The sliding groove 101 extends along the second direction, and the connecting block 13 is slidably connected to the fixed plate 10 through the sliding groove 101.

[0104] The first and second directions in this embodiment can be referred to the description above, and will not be repeated here.

[0105] In this embodiment, the connecting block 13 can be slidably connected to the slide groove 101 via a slider.

[0106] In use, by adjusting the position of the connecting block 13 in the Y-axis direction, since the connecting block 13 is connected to the connecting plate 121 and the plug 122 is connected to the connecting plate 121, the position of the plug 122 in the Y-axis direction can be adjusted synchronously so that the plug 122 can be aligned with the liquid injection port on the battery cell.

[0107] According to some embodiments of this application, a flexible pad is provided on the side of the gripper 11 facing the battery cell.

[0108] The flexible pad in this embodiment can be a rubber pad, a silicone pad, etc., and is not limited here.

[0109] By setting a flexible pad on the side of the clamp 11 facing the battery cell, when the clamp 11 holds the battery cell, the clamp 11 contacts the side of the battery cell through the flexible pad, thus avoiding damage to the side of the battery cell.
