Description

Technical Field

[0001] This application relates to the field of battery processing equipment technology, and in particular to a clamping mechanism, a positioning device, and battery processing equipment. Background Technology

[0002] In the production and processing of cylindrical batteries, it is necessary to transfer or clamp the cylindrical batteries for processing.

[0003] In related technologies, clamping mechanisms are used to clamp cylindrical batteries. The clamping mechanism consists of two clamping parts that work together to hold the battery. When the driving component drives the two clamping parts to move closer or further apart, the two clamping parts may tilt to one side, which can cause the battery to tilt. When the battery is transferred or processed by the clamping mechanism, the shift in the battery's position will affect the transfer or processing of the battery. Utility Model Content

[0004] This application discloses a clamping mechanism, a positioning device, and a battery processing equipment, which can solve the problem that the two clamping parts will tilt to one side.

[0005] To achieve the above objectives, firstly, this application discloses a clamping mechanism, comprising:

[0006] A first clamping assembly, the first clamping assembly including a first connecting end and a first clamping end;

[0007] A second clamping assembly is disposed opposite to the first clamping assembly, and the second clamping assembly includes a second connecting end and a second clamping end;

[0008] Mounting assembly, wherein both the first clamping assembly and the second clamping assembly are rotatably connected to the mounting assembly; and

[0009] A driving component capable of driving the first connecting end and the second connecting end to move toward or away from each other, so that the first clamping end and the second clamping end can rotate relative to the mounting component in opposite directions or toward each other.

[0010] Because the first clamping assembly and the second clamping assembly move as a whole, their positions are prone to misalignment. However, compared with the prior art, this application restricts the positions of the first clamping assembly and the second clamping assembly by installing components, so that the first clamping end of the first clamping assembly and the second clamping end of the second clamping assembly move closer or further apart by rotation. The first clamping end and the second clamping end clamp the first workpiece only by the direction of rotation, thereby avoiding misalignment between the first clamping assembly and the second clamping assembly, and thus avoiding misalignment when the clamping mechanism clamps the first workpiece for transfer or processing.

[0011] Optionally, the first clamping assembly includes a first clamping portion, with the first clamping end located at the end of the first clamping portion; the second clamping assembly includes a second clamping portion, with the second clamping end located at the end of the second clamping portion, and a clamping space for accommodating the first workpiece is formed between the first clamping portion and the second clamping portion.

[0012] By creating a clamping space between the first clamping part and the second clamping part to accommodate the first workpiece, the clamping space can serve as a limit, thereby enabling the first clamping part and the second clamping part to clamp the first workpiece more stably.

[0013] Optionally, the first clamping part is provided with at least one first roller on the side facing the clamping space, the first roller is rotatable and can abut against the first workpiece;

[0014] The second clamping part has at least one second roller on the side facing the clamping space. The second roller is movable and can abut against the first workpiece.

[0015] When the first workpiece moves toward the first clamping assembly, after the workpiece moves into the clamping space, since the first clamping assembly and the second clamping assembly have already clamped the first workpiece, but the first workpiece will continue to move, the first clamping part is provided with a first roller facing the clamping space, and the second clamping part is provided with a second roller facing one side of the clamping space. The first roller and the second roller can play a guiding role, which can reduce the friction between the first clamping assembly and the second clamping assembly relative to the workpiece, so that the workpiece can continue to move along the second direction.

[0016] Optionally, the clamping mechanism further includes:

[0017] A first connecting component connects the first connecting end and the driving end of the driving component, and the driving component can drive the first connecting end to move through the first connecting component;

[0018] A second connecting component connects the second connecting end and the driving end of the driving component, and the driving component can drive the second connecting end to move through the second connecting component.

[0019] By setting the first connecting component, the first connecting component can connect the first connecting end and the driving end of the driving component. In other words, the first connecting component can act as an adapter, making it more convenient to connect the first connecting end and the driving end of the driving component.

[0020] Optionally, the clamping mechanism further includes a guide rail, wherein the first connecting component is slidably connected to the guide rail, and the second connecting component is slidably connected to the guide rail.

[0021] The guide rail provides guidance for the first connecting component; when the driving component drives the second connecting component to move, the second connecting component will move relative to the guide rail, which provides guidance for the second connecting component; the guide rail can prevent the first and second connecting components from deviating when they move, that is, it can prevent the first clamping component and the second clamping component from deviating.

[0022] Optionally, the clamping mechanism further includes an elastic element disposed between the first connecting component and the second connecting component.

[0023] The elastic element is disposed between the first connecting component and the second connecting component. That is, one end of the elastic element is connected to the first connecting component, and the other end of the elastic element is connected to the second connecting component. The direction of the elastic force of the elastic element is a first direction. Specifically, the elastic element is always in a compressed state between the first connecting component and the second connecting component. Therefore, the elastic force of the elastic element is away from the middle of the elastic element, that is, towards the first connecting component and the second connecting component. Under the action of the elastic force of the elastic element, the first connecting end and the second connecting end of the first clamping component will move in opposite directions, and the first clamping end and the second clamping end will move towards each other, which can improve the clamping force of the first clamping part and the second clamping part on the workpiece.

[0024] Optionally, the clamping mechanism further includes a first limiting part and a second limiting part, the first limiting part and the second limiting part being spaced apart, the first connecting component being movable to abut against the first limiting part, and the second connecting component being movable to abut against the second limiting part.

[0025] The clamping mechanism also includes a first limiting part and a second limiting part; wherein, the first limiting part is located on the side of the first connecting component away from the second connecting component, and the second limiting part is located on the side of the second connecting component away from the first connecting component, that is, the first limiting part and the second limiting part are spaced apart, and the first connecting component and the second connecting component are located between the first limiting part and the second limiting part. When the first connecting component moves away from the second connecting component, the first limiting part can limit the movement range of the first connecting component; when the second connecting component moves away from the first connecting component, the second limiting part can limit the movement range of the second connecting component. In other words, the first limiting part and the second limiting part can limit the maximum movement range between the first connecting component and the second connecting component, that is, they can limit the minimum distance between the first clamping part and the second clamping part, which can prevent the first workpiece from being damaged due to excessive clamping force.

[0026] Optionally, the drive assembly includes a transmission component, the transmission component includes a mounting end face, the mounting end face is provided with a first mounting portion and a second mounting portion, and the line connecting the first mounting portion and the second mounting portion passes through the center of the mounting end face;

[0027] The first connecting component is connected to the transmission member at the first mounting part, and the second connecting component is connected to the transmission member at the second mounting part. The transmission member is rotatable and can adjust the distance between the first mounting part and the second mounting part.

[0028] The drive assembly includes a transmission component, which includes a mounting end face. A first mounting portion and a second mounting portion are provided on the mounting end face, and the line connecting the first mounting portion and the second mounting portion passes through the center of the mounting end face. A first connecting component is connected to the transmission component at the first mounting portion, and a second connecting component is connected to the transmission component at the second mounting portion. The transmission component is rotatable, so the distance between the first mounting portion and the second mounting portion changes with the rotation of the transmission component. Therefore, the first connecting component and the second connecting component move accordingly, thereby enabling the first clamping portion and the second clamping portion to move closer to or further away from each other to clamp or release the workpiece.

[0029] Secondly, this application discloses a positioning device, comprising:

[0030] In any of the clamping mechanisms described in the first aspect above, the mounting assembly includes a first mounting member and a second mounting member, the first mounting member being disposed on the second mounting member, and both the first clamping assembly and the second clamping assembly being rotatably connected to the first mounting member;

[0031] A support member is located on the side of the first clamping assembly opposite to the first mounting member and is disposed on the second mounting member. The support member is used to support the first workpiece.

[0032] The feeding mechanism includes a second feeding component, which is located on the side of the first mounting member away from the first clamping component and is disposed on the second mounting member. The second feeding component includes an adsorption part for adsorbing a second workpiece.

[0033] The carrier and the second feeding assembly are configured such that when the carrier and the second feeding assembly are close to each other, the second workpiece can dock with the first workpiece.

[0034] The second feeding component also includes a second positioning part.

[0035] Optionally, the second positioning part is annular and is disposed around the adsorption part.

[0036] Optionally, the second positioning part includes at least one positioning protrusion.

[0037] Optionally, the second positioning part includes a plurality of positioning protrusions, which are arranged around the adsorption part and spaced apart.

[0038] Optionally, the feeding mechanism further includes:

[0039] A first feeding assembly, comprising a carrier, a first mounting component for supporting the carrier, the carrier comprising a supporting part and a first positioning part, the supporting part for supporting the second workpiece;

[0040] The second positioning part can cooperate with the first positioning part, and the adsorption part can adsorb the second workpiece on the supporting part.

[0041] Thirdly, this application discloses a battery processing apparatus, comprising:

[0042] Rotary tower;

[0043] Multiple positioning devices as described in the second aspect above, wherein the second mounting component of each positioning device is mounted on the turret;

[0044] The conveyor is capable of transporting the carrier containing the second workpiece to the first mounting component, and the conveyor is also capable of unloading the carrier.

[0045] A driving component, configured to drive the carrier and the second feeding assembly to move closer to or further away from each other when the turret drives the positioning device to rotate;

[0046] A welding device, the welding device including a welding head, the welding head being disposed on a first side of the rotation path of the positioning device, the first side being the side of the first mounting member facing away from the first clamping assembly.

[0047] Compared with the prior art, the beneficial effects of this application are as follows:

[0048] In this application, since the first clamping component and the second clamping component move as a whole, the position between the first clamping component and the second clamping component is prone to deviation. However, compared with the prior art, this application restricts the position of the first clamping component and the second clamping component by installing components, so that the first clamping end of the first clamping component and the second clamping end of the second clamping component move closer or further away from each other by rotation. The first clamping end and the second clamping end clamp the first workpiece only by the direction of rotation, thereby avoiding deviation between the first clamping component and the second clamping component, and thus avoiding deviation when the clamping mechanism clamps the first workpiece for transfer or processing.

[0077] Before explaining the technical solution of the application, the background technology of this application shall be explained first.

[0078] In the production and processing of cylindrical batteries, it is necessary to transfer or clamp the cylindrical batteries for processing.

[0079] In related technologies, clamping mechanisms are used to clamp cylindrical batteries. These mechanisms consist of two clamping parts that work together to hold the battery. However, when the driving assembly moves the two clamping parts closer or further apart, they may tilt to one side, causing the battery to become misaligned. This misalignment affects the transfer or processing of the battery during transport or processing. Therefore, this application provides a novel clamping mechanism to address these problems.

[0080] The technical solution of this application will be described below with reference to specific embodiments and accompanying drawings.

[0081] Figure 1 This is a schematic diagram of the structure of a positioning device 200 provided in one embodiment of this application. Figure 2 yes Figure 1 The structural diagram of the positioning device 200, with some parts omitted, is shown in the attached diagram. Figure 1 and Figure 2 The clamping mechanism 100 includes a first clamping component 1, a second clamping component 2, a mounting component 3, and a driving component 4. The first clamping component 1 includes a first connecting end 11 and a first clamping end 12. The second clamping component 2 is disposed opposite to the first clamping component 1 and includes a second connecting end 21 and a second clamping end 22. Both the first clamping component 1 and the second clamping component 2 are rotatably connected to the mounting component 3. The driving component 4 can drive the first connecting end 11 and the second connecting end 21 along a first direction (…). Figure 2 The first clamping end 12 and the second clamping end 22 can move towards or away from each other relative to the mounting assembly 3 in the second direction (X-axis direction) so that the first clamping end 12 and the second clamping end 22 can rotate relative to the mounting assembly 3 in the second direction (X-axis direction). Figure 2 Rotate in opposite directions or towards each other (in the Z-axis direction).

[0082] The first direction intersects with the second direction.

[0083] In this embodiment, the clamping mechanism 100 includes a first clamping component 1, a second clamping component 2, a mounting component 3, and a driving component 4.

[0084] The first clamping component 1 and the second clamping component 2 are arranged opposite to each other. The first clamping component 1 and the second clamping component 2 work together to clamp the first workpiece A1. The first workpiece A1 can be a cylindrical battery, a prismatic battery, a soft-pack battery or other types of batteries. The workpiece can also be other products. This application does not limit this.

[0085] Further explanation: The first clamping assembly 1 includes a first connecting end 11 and a first clamping end 12, which are located at opposite ends of the first clamping assembly 1; the second clamping assembly 2 includes a second connecting end 21 and a second clamping end 22, which are located at opposite ends of the second clamping assembly 2. The portion of the first clamping assembly 1 near the first clamping end 12 and the portion of the second clamping assembly 2 near the second clamping end 22 work together to clamp the first workpiece A1.

[0086] The first clamping assembly 1 is rotatably connected to the mounting assembly 3. Specifically, see [link to details]. Figure 2 The first connecting end 11 and the first clamping end 12 have a first connection point 14. The first clamping assembly 1 is rotatably connected to the mounting assembly 3 at the first connection point 14. Therefore, the first clamping assembly 1 can rotate relative to the mounting assembly 3 about a second direction. In other words, the first clamping end 12 and the first connecting end 11 can rotate about the second direction in opposite directions.

[0087] The second clamping assembly 2 is rotatably connected to the mounting assembly 3, specifically, see [link to details]. Figure 2 The second connecting end 21 and the second clamping end 22 have a second connection point 24. The second clamping assembly 2 is rotatably connected to the mounting assembly 3 at the second connection point 24. Therefore, the second clamping assembly 2 can rotate relative to the mounting assembly 3 about a second direction. In other words, the second clamping end 22 and the second connecting end 21 can rotate about the second direction in opposite directions.

[0088] Therefore, in the prior art, since the first clamping component 1 and the second clamping component 2 move as a whole, the position between the first clamping component 1 and the second clamping component 2 is prone to deviation. However, compared with the prior art, this application restricts the position of the first clamping component 1 and the second clamping component 2 by installing component 3, so that the first clamping end 12 of the first clamping component 1 and the second clamping end 22 of the second clamping component 2 move closer or further away from each other by rotation. The first clamping end 12 and the second clamping end 22 clamp the first workpiece A1 only by the direction of rotation, thereby avoiding deviation between the first clamping component 1 and the second clamping component 2, and thus avoiding deviation when the clamping mechanism 100 clamps the first workpiece A1 for transfer or processing.

[0089] To further explain, the driving component 4 can drive the first connecting end 11 to move along the first direction, and the driving component 4 can drive the second connecting end 21 to move along the first direction; when the first connecting end 11 and the second connecting end 21 move towards each other along the first direction, the first clamping end 12 and the second clamping end 22 will rotate around the second direction in a direction away from each other; when the first connecting end 11 and the second connecting end 21 move away from each other along the first direction, the first clamping end 12 and the second clamping end 22 will rotate around the second direction in a direction closer to each other.

[0090] In some embodiments, see Figure 2 , Figure 3 and Figure 4 , Figure 3 yes Figure 1 A schematic diagram of the positioning device 200 from another perspective. Figure 4 yes Figure 3 The image shows a partial enlarged view of the positioning device 200 at position A. The first clamping assembly 1 includes a first clamping part 13, and a first clamping end 12 is located at the end of the first clamping part 13. The second clamping assembly 2 includes a second clamping part 23, and a second clamping end 22 is located at the end of the second clamping part 23. A clamping space 20 for accommodating the first workpiece A1 is formed between the first clamping part 13 and the second clamping part 23.

[0091] The first clamping part 13 is provided with at least one first roller 131 on the side facing the clamping space 20. The first roller 131 is rotatable about a direction intersecting the second direction and is able to abut against the first workpiece A1.

[0092] The second clamping part 23 is provided with at least one second roller 231 on the side facing the clamping space 20. The second roller 231 can rotate about a direction intersecting the second direction and can abut against the first workpiece A1.

[0093] The first clamping assembly 1 includes a first clamping portion 13, and a first clamping end 12 is located at the end of the first clamping portion 13. Specifically, the first clamping portion 13 is the part of the first clamping assembly 1 that is close to the first clamping end 12. The second clamping assembly 2 includes a second clamping portion 23, and a second clamping end 22 is located at the end face of the second clamping portion 23. Specifically, the second clamping portion 23 is the part of the second clamping assembly 2 that is close to the second clamping end 22. A clamping space 20 is formed between the first clamping portion 13 and the second clamping end 22. The clamping space 20 is used to accommodate a workpiece, and the first clamping portion 13 and the second clamping portion 23 can clamp the workpiece located in the clamping space 20.

[0094] To further explain, at least one first roller 131 is provided on the side of the first clamping part 13 facing the clamping space 20. The rotation direction of the first roller 131 is a direction intersecting with the second direction. Specifically, the first direction intersects with the third direction. Figure 3 A first plane is formed in the Y-axis direction, and the rotation direction of the first roller 131 is any angle within the first plane; at least one second roller 231 is provided on the side of the second clamping part 23 facing the clamping space 20, and the rotation direction of the second roller 231 is the direction intersecting with the second direction. Specifically, the rotation direction of the second roller 231 is any angle within the first plane; wherein, the rotation direction of the first roller 131 and the rotation direction of the second roller 231 can be the same or different.

[0095] When the first workpiece A1 moves toward the first clamping assembly 1 in the second direction, after the workpiece moves into the clamping space 20, since the first clamping assembly 1 and the second clamping assembly 2 have already clamped the first workpiece A1, but the first workpiece A1 will continue to move along the second direction, the first clamping part 13 is provided with a first roller 131 facing the clamping space 20, and the second clamping part 23 is provided with a second roller 231 facing one side of the clamping space 20. The first roller 131 and the second roller 231 can play a guiding role, which can reduce the friction between the first clamping assembly 1 and the second clamping assembly 2 relative to the workpiece, so that the workpiece can continue to move along the second direction.

[0096] In some embodiments, see Figure 2 The clamping mechanism 100 further includes a first connecting component 5a and a second connecting component 5b, wherein the first connecting component 5a connects the first connecting end 11 and the driving end of the driving component 4, and the driving component 4 can drive the first connecting end 11 along a first direction via the first connecting component 5a. Figure 2 The second connecting component 5b connects the second connecting end 21 and the driving end of the driving component 4. The driving component 4 can drive the second connecting end 21 to move along the first direction through the second connecting component 5b.

[0097] By setting the first connecting component 5a, the first connecting component 5a can connect the first connecting end 11 and the driving end of the driving component 4. That is, the first connecting component 5a can act as an adapter, making it more convenient to connect the first connecting end 11 and the driving end of the driving component 4.

[0098] The function of the second connecting component 5b is similar to that of the first connecting component 5a, and will not be described again in this embodiment.

[0099] In some embodiments, see Figure 2The clamping mechanism 100 also includes a guide rail 6, and the first connecting component 5a is connected to the guide rail 6 along a first direction ( Figure 2 The second connecting component 5b is slidably connected to the guide rail 6 along the first direction (X-axis direction).

[0100] The clamping mechanism 100 also includes a guide rail 6, the length direction of which is a first direction. A first connecting component 5a is slidably connected to the guide rail 6, and a second connecting component 5b is slidably connected to the guide rail 6. The first connecting component 5a and the second connecting component 5b are arranged along the first direction. When the driving component 4 drives the first connecting component 5a to move along the first direction, the first connecting component 5a will move relative to the guide rail 6, and the guide rail 6 provides a guiding function for the first connecting component 5a. When the driving component 4 drives the second connecting component 5b to move along the first direction, the second connecting component 5b will move relative to the guide rail 6, and the guide rail 6 provides a guiding function for the second connecting component 5b. The guide rail 6 can prevent the first connecting component 5a and the second connecting component 5b from deviating when moving along the first direction, that is, it can prevent the first clamping component 1 and the second clamping component 2 from deviating.

[0101] In some embodiments, see Figure 2 The clamping mechanism 100 also includes an elastic element 7, which is disposed between the first connecting component 5a and the second connecting component 5b.

[0102] The elastic element 7 is disposed between the first connecting component 5a and the second connecting component 5b. That is, one end of the elastic element 7 is connected to the first connecting component 5a, and the other end of the elastic element 7 is connected to the second connecting component 5b. The direction of the elastic force of the elastic element 7 is a first direction. Specifically, the elastic element 7 is always in a compressed state between the first connecting component 5a and the second connecting component 5b. Therefore, the elastic force of the elastic element 7 is away from the middle of the elastic element 7, that is, towards the first connecting component 5a and the second connecting component 5b. Under the action of the elastic force of the elastic element 7, the first connecting end 11 and the second connecting end 21 of the first clamping component 1 and the second clamping end 22 will move in opposite directions, and the first clamping end 12 and the second clamping end 22 will move towards each other, which can improve the clamping force of the first clamping part 13 and the second clamping part 23 on the workpiece.

[0103] The elastic element 7 mentioned above can be a compression spring or any other possible elastic element 7, and this embodiment does not limit it.

[0104] In some embodiments, see Figure 2 and Figure 5 , Figure 5 yes Figure 2 A partial enlarged view at position B shows that the clamping mechanism 100 also includes a first limiting part 8a and a second limiting part 8b, which are along a first direction ( Figure 5 The first connecting component 5a is positioned at intervals along the X-axis direction, and the first connecting component 5b is positioned along the first direction to abut against the first limiting part 8a, and the second connecting component 5b is positioned along the first direction to abut against the second limiting part 8b.

[0105] The clamping mechanism 100 also includes a first limiting part 8a and a second limiting part 8b; wherein, the first limiting part 8a is disposed on the side of the first connecting component 5a away from the second connecting component 5b, and the second limiting part 8b is disposed on the side of the second connecting component 5b away from the first connecting component 5a. That is, the first limiting part 8a and the second limiting part 8b are spaced apart in a first direction, and the first connecting component 5a and the second connecting component 5b are located between the first limiting part 8a and the second limiting part 8b. When the first connecting component 5a moves away from the second connecting component 5b along the first direction, the first limiting part 8a can limit the movement range of the first connecting component 5a. When the second connecting component 5b moves away from the first connecting component 5a along the first direction, the second limiting part 8b can limit the movement range of the second connecting component 5b. In other words, the first limiting part 8a and the second limiting part 8b can limit the maximum movement range between the first connecting component 5a and the second connecting component 5b. In other words, they can limit the minimum distance between the first clamping part 13 and the second clamping part 23, thus preventing the first workpiece A1 from being damaged due to excessive clamping force.

[0106] In addition, the first limiting part 8a and the second limiting part 8b are respectively provided at both ends of the guide rail 6. When the first clamping assembly 1 and the second clamping assembly 2 move to the ends of the guide rail 6, the first limiting part 8a and the second limiting part 8b can play a blocking role.

[0107] The first limiting part 8a can be a first limiting rod or a first limiting plate; the second limiting part 8b can be a first limiting rod or a first limiting plate.

[0108] Both the first limiting part 8a and the second limiting part 8b are adjustable. By adjusting the distance between the first limiting part 8a and the second limiting part 8b, the distance between the first clamping part 13 and the second clamping part 23 can be adjusted to accommodate workpieces of different sizes.

[0109] In some embodiments, see Figure 5 The drive assembly 4 includes a transmission component 41, which includes a mounting end face 411. The mounting end face 411 is provided with a first mounting portion 4111 and a second mounting portion 4112. The line connecting the first mounting portion 4111 and the second mounting portion 4112 passes through the center of the mounting end face 411.

[0110] The first connecting component 5a is connected to the transmission member 41 at the first mounting portion 4111, and the second connecting component 5b is connected to the transmission member 41 at the second mounting portion 4112. The transmission member 41 is capable of rotating around a third direction. Figure 5 The distance between the first mounting part 4111 and the second mounting part 4112 in the first direction can be adjusted by rotating the Y-axis.

[0111] The drive assembly 4 includes a transmission member 41, which includes a mounting end face 411. A first mounting portion 4111 and a second mounting portion 4112 are provided on the mounting end face 411. The line connecting the first mounting portion 4111 and the second mounting portion 4112 passes through the center of the mounting end face 411. A first connecting component 5a is connected to the transmission member 41 at the first mounting portion 4111, and a second connecting component 5b is connected to the transmission member 41 at the second mounting portion 4112. The transmission member 41 can rotate around a third direction. Therefore, the distance between the first mounting portion 4111 and the second mounting portion 4112 in the first direction will change as the transmission member 41 rotates around the third direction. Thus, the first connecting component 5a and the second connecting component 5b will move along the first direction, thereby enabling the first clamping portion 13 and the second clamping portion 23 to move closer or further apart to clamp or release the workpiece.

[0112] The mounting end face 411 has a center. If the mounting end face 411 is circular, the center is a dot; if the mounting end face 411 is square, the center is the intersection of the two diagonals of the square; if the mounting end face 411 is irregular in shape, the center can be the intersection of two perpendicular intersecting lines.

[0113] In an alternative embodiment, when the drive assembly 4 includes a transmission member 41, the drive assembly 4 also includes a motor, the output shaft of which is connected to the transmission member 41, and the motor is capable of driving the transmission member 41 to rotate about a third direction.

[0114] In another alternative implementation, such as Figure 5 and Figure 6 As shown, Figure 6 The diagram shows the structure of the positioning device 200 in section 2 from another perspective. The drive assembly 4 includes a transmission member 41, a swing arm 42, and a roller 43. The swing arm 42 is located at the end of the transmission member 41 away from the mounting end face 411. The roller 43 is connected to the swing arm 42 and can rotate around its own axis. In this embodiment, the battery processing equipment 300 includes a turntable and a cam. The roller 43 can move along the cam. The cam includes a protrusion and a recess. The roller 43 passes through the protrusion and the recess, enabling the transmission member 41 to rotate around a third direction, thereby allowing the first clamping part 13 and the second clamping part 23 to move closer or further apart.

[0115] An embodiment of this application also provides a positioning device 200, see [link to relevant documentation] Figure 1 , Figure 2 and Figure 7 , Figure 7 yes Figure 1 The positioning device 200 is shown in a structural schematic diagram from another perspective. The positioning device 200 includes a clamping mechanism 100, a carrier 201, and a feeding mechanism 202. The mounting assembly 3 includes a first mounting member 31 and a second mounting member 32. The first mounting member 31 is disposed on the second mounting member 32. Both the first clamping assembly 1 and the second clamping assembly 2 are rotatably connected to the first mounting member 31. The carrier 201 is positioned along a second direction (…). Figure 7 (in the Z-axis direction) is located on the side of the first clamping assembly 1 opposite to the first mounting member 31. Figure 1 The first mounting member 31 is located on the lower side of the first mounting member 31, and is movably disposed on the second mounting member 32 along the second direction. The carrier member 201 is used to carry the first workpiece A1.

[0116] The feeding mechanism 202 includes a second feeding component 2021, which is located along a second direction on the side of the first mounting member 31 opposite to the first clamping component 1. Figure 1 (on the upper side of the first mounting member 31), and movably disposed on the second mounting member 32 along the second direction, see [reference] Figure 8 , Figure 8 Figure 1 The second feeding component 2021 is shown in a schematic diagram from another perspective. The second feeding component 2021 includes an adsorption part 20211, which is used to adsorb the second workpiece A2.

[0117] The carrier 201 and the second feeding assembly 2021 are configured such that when the carrier 201 and the second feeding assembly 2021 approach each other in the second direction, the second workpiece A2 can dock with the first workpiece A1.

[0118] Since the carrier 201 is used to carry the first workpiece A1, and the adsorption part 20211 of the second feeding assembly 2021 is used to adsorb the second workpiece A2, and since the carrier 201 is located on the side of the first clamping assembly 1 away from the first mounting assembly 31 along the second direction and is movably disposed on the second mounting assembly 32 along the second direction, and the second feeding assembly 2021 is located on the side of the first mounting assembly 31 away from the first clamping assembly 1 along the second direction and is movably disposed on the second mounting assembly 32 along the second direction, when the carrier 201 and the second feeding assembly 2021 approach each other along the second direction, the second workpiece A2 can be docked with the first workpiece A1, thereby facilitating the welding of the second workpiece A2 to the first workpiece A1.

[0119] The first workpiece A1 can be a battery, and the second workpiece A2 can be a sealing nail.

[0120] Since the clamping mechanism 100 can avoid skewing when clamping the first workpiece A1, when the clamping mechanism 100 is applied to the positioning device 200, the second workpiece A2 can be better aligned with the first workpiece A1, thereby better ensuring that the second workpiece A2 can dock with the first workpiece A1.

[0121] In some embodiments, see Figure 1 and Figure 9 , Figure 9 This is a schematic diagram of another positioning device 200 provided in an embodiment of this application. The feeding mechanism 202 further includes a first feeding component 2022. The first feeding component 2022 includes a carrier 20221. The first mounting member 31 is used to support the carrier 20221. The carrier 20221 includes a supporting part 20221a and a first positioning part 20221b. The supporting part 20221a is used to support the second workpiece A2.

[0122] See Figure 8 The second feeding assembly 2021 also includes a second positioning part 20212, which can cooperate with the first positioning part 20221b, and the adsorption part 20211 can adsorb the second workpiece A2 in the bearing part 20221a.

[0123] The second workpiece A2 is placed in the support part 20221a of the carrier 20221. The first positioning part 20221b cooperates with the second positioning part 20212. The adsorption part 20211 grips the second workpiece A2 in the support part 20221a. Since the first positioning part 20221b and the second positioning part 20212 cooperate, the accuracy of the adsorption part 20211 gripping the second workpiece A2 in the support part 20221a can be improved, thereby improving the feeding accuracy.

[0124] In some embodiments, see Figure 8 and Figure 9 The first positioning part 20221b is annular and is arranged around the bearing part 20221a; the second positioning part 20212 is annular and is arranged around the adsorption part 20211.

[0125] When the second positioning part 20212 cooperates with the first positioning part 20221b, even if there is a slight positional deviation between the carrier 20221 and the second feeding assembly 2021, the first positioning part 20221b and the second positioning part 20212 can still cooperate because both the first positioning part 20221b and the second positioning part 20212 are annular. This reduces the cooperation accuracy between the first positioning part 20221b and the second positioning part 20212, improves the positioning efficiency between the first positioning part 20221b and the second positioning part 20212, and thus improves the feeding accuracy of the feeding mechanism.

[0126] In some embodiments, see Figure 8 and Figure 9 The first positioning part 20221b is a positioning groove, and the second positioning part 20212 includes at least one positioning protrusion 20212a, which can be inserted into the interior of the positioning groove.

[0127] With this configuration, multiple positioning protrusions 20212a can be used for positioning simultaneously, thereby achieving higher positioning accuracy.

[0128] In some embodiments, see Figure 8 and Figure 9 The second positioning part 20212 includes a plurality of positioning protrusions 20212a, which are arranged around the adsorption part 20211 and spaced apart. All of the plurality of positioning protrusions 20212a can be inserted into the interior of the positioning groove.

[0129] By arranging multiple positioning protrusions 20212a around the adsorption part 20211, positioning can be formed from one circumference of the adsorption part 20211, thereby enabling the adsorption part 20211 and the support part 20221a to be better aligned, and thus better ensuring that the adsorption part 20211 can adsorb the second workpiece A2 on the support part 20221a.

[0130] Figure 10 This is a schematic diagram of the structure of a battery processing apparatus 300 provided in one embodiment of this application. See also... Figure 10 The battery processing equipment 300 includes a turret 301, multiple positioning devices 200, a conveyor 302, a drive unit (not shown in the figure), and a welding device 304. Each positioning device 200 has a second mounting part 32 mounted on the turret 301. The conveyor 302 can move the carrier 20221 containing the second workpiece A2 to the first mounting part 31. The conveyor 302 can also unload the carrier 20221.

[0131] The drive unit is configured to drive the carrier 201 and the second feeding assembly 2021 to move closer to or further away from each other along the second direction when the turret 301 drives the positioning device 200 to rotate. The welding device 304 includes a welding head, which is disposed on the first side of the rotation path of the positioning device 200 along the second direction. The first side is the side of the first mounting member 31 that is away from the first clamping assembly 1.

[0132] In this embodiment, when the second workpiece A2 is welded to the first workpiece A1 by the battery processing equipment 300, firstly, the carrier 20221 on which the second workpiece A2 is placed can be transferred to the first mounting member 31 by the conveyor 302. Then, the second workpiece A2 on the bearing part 20221a of the carrier 20221 can be adsorbed by the adsorption part 20211, so that the second workpiece A2 is detached from the carrier 20221. Then, the carrier 20221 can be unloaded from the first mounting member 31 by the conveyor 302.

[0133] Next, with the first workpiece A1 supported on the carrier 201, as the turret 301 drives the positioning device 200 to rotate, the driving component can drive the carrier 201 and the second feeding assembly 2021 to move closer to each other in the second direction, so that the second workpiece A2 docks with the first workpiece A1. After the second workpiece A2 docks with the first workpiece A1, as the positioning device 200 follows the turret 301 to rotate, when it passes the welding head, the welding head can weld the second workpiece A2 and the first workpiece A1, thereby achieving the purpose of welding the second workpiece A2 to the first workpiece A1.

[0134] Since the welding head can weld the second workpiece A2 and the first workpiece A1 during the rotation of the turret 301, that is, it can weld the second workpiece A2 and the first workpiece A1 during their flight, the welding efficiency is higher.

[0135] The aforementioned driving component can be a cam or any other component capable of driving the carrier 201 and the second feeding assembly 2021 to move closer or further apart in the second direction. This embodiment does not limit this.

[0136] The aforementioned welding head can be a laser welding head.

[0137] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
