Abstract

The application belongs to the technical field of battery manufacturing, and discloses a battery cell clamp and a release mechanism. The battery cell clamp comprises a carrier for carrying a battery cell. The battery cell clamp further comprises a first clamping unit, which comprises a first clamping piece and a first pushing piece. When the first pushing piece is subjected to an external force, the first pushing piece moves away from the first clamping piece to release the battery cell. When the first pushing piece is not subjected to an external force, the first pushing piece moves close to the first clamping piece to clamp the battery cell. The first pushing piece moves close to the first clamping piece to clamp the battery cell, so that a clamping force is provided without using an external force such as a cylinder, the occupied space of multiple cylinders is reduced, and the use of fixed cylinders is limited. The release mechanism comprises a driving part and a first extending piece arranged at the output end of the driving part. The first extending piece corresponds to the first pushing piece. When the battery cell is released, the first extending piece applies an external force to the first pushing piece to release the battery cell, which is convenient to operate.

Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a cell clamp and release mechanism. Background Technology

[0002] As a crucial power component for electric vehicles, batteries are developing rapidly. During battery production, many stations on the production line require clamping and positioning of battery cells. However, existing cell clamping devices typically use multiple sets of cylinders, requiring multiple cylinders at each station to hold the workpiece. This approach is problematic because it occupies significant production space and increases costs. Furthermore, multiple cylinders can easily lead to overvoltage of the battery cells. In addition, cylinders are generally suitable for relatively fixed locations. When workpieces are being processed on a mobile production line, cylinders need to be installed at each station, and frequent switching of these cylinders for clamping and releasing the cells limits their application scenarios. Therefore, a new battery cell clamping device is urgently needed to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a battery cell clamp that maintains a clamped state at different workstations without requiring multiple cylinders at each workstation, thereby reducing the space occupied by multiple cylinders and reducing the limitations of using fixed cylinders. Furthermore, the release mechanism can quickly release the battery cell clamped by the battery cell clamp.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Battery cell clamps, including:

[0006] A carrier for carrying battery cells;

[0007] A first clamping unit includes a first clamping member and a first pushing member. Two first clamping members are disposed on opposite sides of the carrier. The two first clamping members can move closer to or further away from each other to clamp or release the battery cell. The first pushing member moves relative to the first clamping members. When the first pushing member is subjected to an external force, the first pushing member moves away from the two first clamping members to release the battery cell. When the first pushing member is not subjected to an external force, the first pushing member abuts against the two first clamping members to clamp the battery cell.

[0008] Preferably, the first clamping member includes a clamping plate disposed on both sides of the carrier. The first clamping member also has a clamping abutment, the middle part of which is connected to the carrier. A first end of the clamping abutment is connected to the clamping plate, and a second end of the clamping abutment is away from the clamping plate. The height of the first end of the clamping abutment is higher than the height of the second end of the clamping abutment. The second end of the clamping abutment is connected to the first end of a first elastic member, and the second end of the first elastic member is connected to the carrier. The first elastic member gives the first clamping member a tendency to release the battery cell.

[0009] Preferably, the first pushing member includes a pushing plate disposed below the second end of the clamping abutment. A supporting elastic member is provided on the side of the pushing plate opposite to the clamping abutment, and the supporting elastic member supports the pushing plate to push the clamping abutment upward. A protrusion protruding from the surface of the pushing plate is also provided on the side of the pushing plate opposite to the clamping abutment. The first pushing member also has a sliding groove that slides relative to the protrusion. The height of the opening of the sliding groove is higher than the height of the inner bottom of the sliding groove. The opening of the sliding groove faces the protrusion so that the protrusion can enter and exit the sliding groove.

[0010] Preferably, the first clamping unit further includes a first slide rail disposed on the carrier, a slide block disposed on the first slide rail, the sliding groove being mounted on the slide block to be able to approach and move away from the protrusion, and a fourth elastic member disposed between the slide block and the carrier along the moving direction of the slide block.

[0011] Preferably, the device also includes a second clamping unit, which includes a second clamping member. The two second clamping members are located on both sides of any one of the first clamping members, and the second clamping members can be close to or away from the battery cell.

[0012] Preferably, the second clamping unit further includes a second pushing member disposed below the carrier, the second clamping member being disposed on the second pushing member, and the second clamping unit further includes a second elastic member disposed along the moving direction of the second clamping member, one end of the second elastic member being fixed to the second pushing member, and the other end of the second elastic member being fixed to the carrier.

[0013] Preferably, the device also includes a third clamping unit, which includes a third clamping member. Two third clamping members are arranged opposite to each other and are disposed between two first clamping members. The third clamping members can move closer to or further away from each other to clamp the battery cell from the side.

[0014] Preferably, the third clamping unit further includes a third elastic member disposed along the moving direction of the third clamping member, one end of the third elastic member being fixed to the third clamping member, the other end of the third elastic member being fixed to the carrier, and a third pushing member being disposed on the third clamping member and connected to the third clamping member.

[0015] A release mechanism for releasing a battery cell held by a battery cell clamp as described above includes a drive unit and a first extension member disposed at the output end of the drive unit. The first extension member corresponds to a first push member in the first clamping unit so as to push the first push member to move to release the battery cell.

[0016] Preferably, the driving part is provided with a second protrusion and a third protrusion, and the battery cell clamp also has a second clamping unit. The second clamping unit has a second pushing member. The second pushing member is connected to the second clamping member. The second protrusion corresponds to the second pushing member so as to push the second pushing member to move to release the battery cell.

[0017] The battery cell clamp also has a third clamping unit, which has a third pushing member connected to the third clamping member. The third protruding member corresponds to the third pushing member so as to push the third pushing member to move and release the battery cell.

[0018] Preferably, the driving unit includes a first driving unit and a second driving unit, the first protruding member is disposed at the output end of the first driving unit, and the second protruding member and the third protruding member are disposed at the output end of the second driving unit.

[0019] The beneficial effects of this invention are:

[0020] With the aforementioned carrier, first clamping member, and first pushing member, when the first pushing member is not subjected to external force, it approaches and abuts against the first clamping member to clamp the battery cell. There is no need to use external force such as cylinders to provide clamping force, so that the battery cell remains clamped as it moves between different workstations. This eliminates the need for multiple cylinders at each workstation, reducing the space occupied by multiple cylinders and reducing the limitations of using fixed cylinders. As a result, the carrier can be installed on the processing station and move with the processing station for convenient clamping. When using the release mechanism to release the battery cell clamped by the battery cell clamp, the release mechanism can be placed at the end of the battery cell's movement. The first protruding member applies external force to the first pushing member, causing the first pushing member to move downward away from the first clamping member to quickly release the battery cell, which is convenient for operation.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] like Figure 1-7 As shown, this embodiment provides a battery cell clamp, which includes a carrier 1 for carrying a battery cell 5. The battery cell clamp also has a first clamping unit 2, which includes a first clamping member 21 and a first pushing member 22. The two first clamping members 21 are disposed on opposite sides of the carrier 1, and the two first clamping members 21 can move closer to or further away from each other to clamp or release the battery cell 5. The first pushing member 22 moves relative to the first clamping members 21. When the first pushing member 22 is subjected to an external force, the first pushing member 22 moves away from the two first clamping members 21 to release the battery cell 5. When the first pushing member 22 is not subjected to an external force, the first pushing member 22 moves closer to and abuts against the two first clamping members 21 to clamp the battery cell 5.

[0035] With the carrier 1, the first clamping member 21, and the first pushing member 22 described above, when the first pushing member 22 is not subjected to external force, the first pushing member 22 approaches and abuts against the first clamping member 21 to clamp the battery cell 5. There is no need to use external force such as cylinders to provide clamping force, so that the battery cell 5 always remains clamped when it flows through different workstations. There is no need to equip each workstation with multiple cylinders and frequently switch the cylinders, which reduces the space occupied by multiple cylinders and reduces the usage restrictions of fixed cylinders. Thus, the carrier 1 can be installed on the processing workstation and flow with the processing workstation for convenient clamping. When releasing the battery cell 5, the release mechanism can be placed at the end of the flow of the battery cell 5 to apply external force to the first pushing member 22, so that the first pushing member 22 moves downward away from the first clamping member 21 to release the battery cell, which is convenient for operation.

[0036] The following details this embodiment. A battery cell clamp includes a carrier 1 for carrying a battery cell 5. Specifically, the carrier 1 includes a carrier frame 11 and a carrier base 12. The battery cell 5 is placed on the carrier base 12. Multiple mounting holes are provided at the bottom of the carrier frame 11 for mounting to a processing station, facilitating the installation and movement of the battery cell clamp onto the processing station. The battery cell clamp also has a first clamping unit 2, which includes a first clamping member 21 and a first pushing member 22. Two first clamping members 21 are disposed on opposite sides of the carrier 1, and the two first clamping members 21 can move closer or further apart to clamp or release the battery cell 5. Specifically, the first clamping member 21 includes clamping plates 211. Two clamping plates 211 are disposed opposite each other on both sides of the carrier seat 12. In this embodiment, the clamping plates 211 are elongated and extend along the height direction of the battery cell 5 to better clamp the battery cell 5. It can be understood that an anti-slip layer can be provided on the side of the first clamping member 21 facing the battery cell 5 for pressure buffering and anti-slip. In addition, the first clamping member 21 also includes a clamping abutment member 212. In this embodiment, the clamping abutment member 212 is adapted to the carrier seat 12. Specifically, the carrier seat 12 is provided with a connecting shaft, and the clamping abutment member 212 is adapted to the carrier seat 12 through the connecting shaft. The first end of the clamping abutment 212 is connected to the clamping plate 211, and the second end of the clamping abutment 212 is away from the clamping plate 211. The height of the first end of the clamping abutment 212 is higher than the height of the second end of the clamping abutment 212, that is, the clamping abutment 212 extends obliquely downward from the connection with the first clamping member 21. Thus, when the second end of the clamping abutment 212 moves upward, the first end of the clamping abutment 212 rotates around the adapter shaft, thereby causing the clamping plates 211 to move closer to each other so that the clamping plates 211 can clamp the battery cell 5. Conversely, when the second end of the clamping abutment 212 moves downward, the first end of the clamping abutment 212 rotates around the adapter shaft, thereby causing the clamping plates 211 to move away from each other so that the clamping plates 211 release the battery cell 5. The second end of the clamping abutment 212 is connected to the first end of the first elastic member 25. The second end of the first elastic member 25 is connected to the carrier 1 to provide a restoring tension. The first elastic member 25 makes the first clamping member 21 tend to release the battery cell 5. In this embodiment, the first elastic member 25 is a tension spring. The first elastic member 25 enables the clamping abutment 212 to move away from the clamping plate 211 to release quickly.

[0037] The first pushing member 22 includes a pushing plate 221, which is disposed below the second end of the clamping abutment member 212. A supporting elastic member 222 is disposed on the side of the pushing plate 221 away from the clamping abutment member 212. In this embodiment, one end of the supporting elastic member 222 is connected to the pushing plate 221, and the other end of the supporting elastic member 222 is connected to the carrier frame 11. The supporting elastic member 222 is supported by the pushing plate 221, so that the pushing plate 221 supports and clamps the second end of the abutment member 212, so that when the first pushing member 22 is not subjected to external force, the first pushing member 22 moves upward and abuts the first clamping member 21 to clamp the battery cell 5. In this embodiment, the support elastic element 222 is a compression spring. The compression spring can be adjusted according to the clamping force of the clamping plate 211. When the first pushing member 22 is subjected to external force, causing the pushing plate 221 to descend, the pushing plate 221 moves away from the second end of the clamping abutment member 212, thereby releasing the battery cell 5 from the first clamping member 212. To facilitate the descent of the pushing plate 221, a protrusion 223 is also provided on the side of the pushing plate 221 away from the clamping abutment member 212. The protrusion 223 protrudes from the surface of the pushing plate 221, and a sliding groove 224 facing the protrusion 223 is provided on the carrier frame 11. The sliding groove 224 can slide relative to the protrusion 223. For example, the sliding groove 224 is a U-shaped fixture groove, and the protrusion 223 is a roller protruding from the surface of the push plate 221. The opening of the U-shaped fixture groove faces the roller. The height of the groove opening of the sliding groove 224 is higher than the height of the inner bottom of the sliding groove 224. That is, when the opening of the U-shaped fixture groove contacts the roller, the roller decreases with the height of the groove inside the U-shaped fixture groove, thereby reducing the height of the push plate 221 and moving the push plate 221 away from the second end of the clamping abutment 212. When the sliding groove 224 is reset, the height of the roller increases, and the height of the push plate 221 increases, thereby bringing the push plate 221 closer to the second end of the clamping abutment 212 to clamp the battery cell 5.

[0038] To reduce the contact resistance when the push plate 221 contacts the second end of the clamping abutment 212, an abutment roller is provided at the second end of the clamping abutment 212. To ensure that the stroke of the push plate 221 during its up-and-down movement is linear, a linear bearing 26 is provided on the carrier frame 11, passing through the push plate 221 to ensure the linearity of the push plate 221's up-and-down movement. Furthermore, a first slide rail 23 is also provided on the carrier frame 11, and a slide block 24 is provided on the first slide rail 23. The sliding groove 224 is installed on the slide block 24 to be able to approach and move away from the protrusion 223. In this embodiment, in order to balance the force, two sliding grooves 224 are provided, and they are respectively placed on opposite sides of the slide block 24. Correspondingly, two protrusions 223 are also provided at intervals on the surface of the push plate 221. A fourth elastic element 27 is provided between the slide 24 and the carrier 1 along the moving direction of the slide 24, so that the sliding groove 224 can quickly return to its original position after the external force is lost after the protrusion 223 is pressed down. In this embodiment, the fourth elastic element 27 is a compression spring. A first protrusion is provided on the slide 24. The first protrusion is away from the groove opening direction of the sliding groove 224 to provide a convenient point for external force to be applied to the first pusher 22.

[0039] This embodiment also includes a second clamping unit 3, which further includes a second clamping member 31. The second clamping member 31 is located on both sides of any one of the first clamping members 21. In this embodiment, the second clamping member 31 is located on the side away from the first protrusion. In this embodiment, the second clamping member 31 is a strip plate, and the height of the second clamping member 31 is less than the height of the first clamping member 21. The second clamping member 21 can clamp the battery cell 5. In addition, the second clamping member 31 can also clamp the Mylar film during Mylar film processing to prevent the Mylar film from moving or shifting, thus ensuring a high yield. The second clamping unit 3 also includes a second pushing member 32 disposed below the carrier 1. Specifically, the second pushing member 32 is disposed below the carrier base 12, and the second clamping member 31 is disposed perpendicular to the second pushing member 32, i.e., the two form an L-shape. In other embodiments, the second clamping member 31 and the second pushing member 32 can be integrally formed. In addition, to facilitate resetting, the second clamping unit 3 also includes a second elastic member 33 arranged along the moving direction of the second clamping member 31. One end of the second elastic member 33 is connected to the second pushing member 32, and the other end of the second elastic member 33 is connected to the carrier seat 12. In this embodiment, the second elastic member 33 is a compression spring. In addition, the second pushing member 32 is also provided with a second protrusion. The second protrusion extends in the same direction as the first protrusion to provide a point of application for external force to be applied to the second pushing member 32.

[0040] This embodiment of the battery cell fixture also includes a third clamping unit 4, which includes a third clamping member 41. Two third clamping members 41 are disposed opposite each other on both sides of the carrier base 12, and are positioned between two first clamping members 21. The third clamping members 41 can move closer or further away from each other to clamp the battery cell 5 from the side, thus forming a complementary clamping with the first clamping members 21 and the second clamping members 31 to supplement the clamping force on the side of the battery cell 5. In addition, the third clamping members 41 can also clamp the Mylar film from different sides during Mylar film processing, avoiding the movement and displacement of the Mylar film and ensuring a high yield. Specifically, the top of the third clamping member 41 is bent towards the carrier base 12 to facilitate the clamping of the battery cell 5 placed on the carrier base 12.

[0041] The third clamping unit 4 further includes a third elastic member 43 disposed along the moving direction of the third clamping member 41. In this embodiment, the third elastic member 43 is a compression spring. One end of the third elastic member 43 is connected to the carrier frame 11, and the other end of the third elastic member 43 is connected to the third clamping member 41. A third pushing member 42 is disposed on the third clamping member 41 to compress or release the third elastic member 43 by pushing the third pushing member 42 to move, thereby clamping or releasing the battery cell 5. Specifically, the third pushing member 42 includes a force plate perpendicular to the moving direction of the third clamping member 41. The force plate is connected to the third clamping member 41. The third pushing member 42 also includes a third protrusion disposed on the force plate. In this embodiment, the third protrusion is a roller and is away from the carrier seat 12. The extending directions of the first protrusion and the second protrusion are the same as the direction in which the third protrusion is away from the carrier seat 12. This facilitates the application of external force to the first protrusion, the second protrusion, and the third protrusion from the same direction. Using the above-mentioned cell clamp, the cell 5 can be clamped in multiple directions. The cell clamp can hold the cell 5 without external force intervention, reducing the use of cylinders. The multi-directional clamping also avoids overpressure on the cell 5 and prevents the Mylar film from shifting during Mylar film processing. It is convenient to install the cell clamp in any position on the battery production line, reducing the site restrictions of cylinder use.

[0042] This embodiment also provides a release mechanism for releasing the battery cell 5 held by the battery cell clamp, providing power to the first pusher 22, the second pusher 32, and the third pusher 42. The release mechanism includes a mounting plate, on which a drive unit 40 is provided, and a first extension 10, a second extension 20, and a third extension 30 are provided at the output end of the drive unit 40. Preferably, in this embodiment, the drive unit 40 is a cylinder, and the first extension 10, the second extension 20, and the third extension 30 can extend and retract synchronously. The first extension 10 can push the first pusher 22 in the first clamping unit 2; the second extension 20 can push the second pusher 32 in the second clamping unit 3; and the third extension 30 can push the third pusher 42 in the third clamping unit 4. Specifically, the first protrusion 10, the second protrusion 20, and the third protrusion 30 are push bars. The first protrusion 10 corresponds to the position and number of the first protrusion, and the second protrusion 20 corresponds to the position and number of the second protrusion. When the first protrusion 10 and the second protrusion 20 extend, they can apply a pushing force to the corresponding first and second protrusions, thereby causing the first clamping member 21 and the second clamping member 31 to move and release the battery cell 5. In this embodiment, the third protrusion 30 corresponds to the position and number of the third protrusion. More specifically, the two third protrusions 30 have inclined surfaces on their opposite outer sides. The inclined surfaces extend from the middle of the top of the third protrusion 30 in a direction away from the body of the third protrusion 30. That is, when the third protrusion 30 touches the third protrusion (i.e., the roller), the third protrusion moves along the inclined surface to the opposite outer side of the third protrusion 30, thereby causing the third clamping member 41 to move away from the battery cell 5 and completing the release of the third clamping member 41. Preferably, the drive unit 40 is divided into a first drive unit 401 and a second drive unit 402. The first clamping member 21 is disposed at the output end of the first drive unit 401, and the second protruding member 20 and the third protruding member 30 are disposed at the output end of the second drive unit 402. This structure enables the second clamping member 31 and the third clamping member 41, which can control the clamping of the mylar film, to be controlled by a single drive unit, so as to facilitate the processing of the mylar film.
