Description

Technical Field

[0001] The utility model belongs to the technical field of battery core production equipment, and in particular relates to a tooling fixture used for positioning a plastic shell battery core. Background Art

[0002] As the core component of the battery, the battery cell realizes charging and discharging based on the transmission of ions in the electrolyte and the flow of electrons between the cathode and anode. The battery cell usually includes components such as the cathode, anode, diaphragm, electrolyte and shell. The shell is the external packaging of the battery cell, which plays a role in protecting the internal structure of the battery cell and preventing external pollution. Depending on the shape of the battery cell and the packaging method, the battery cell can use shells of different materials, such as plastic shells.

[0003] At present, in the production process of battery cells, the plastic shell is generally positioned and fixed by a battery cell positioning fixture to facilitate the assembly and turnover of the plastic shell battery cells. The existing battery cell positioning fixture includes a limit block, and a first clamping block and a second clamping block for clamping the plastic shell are arranged on one side of the limit block. Springs are arranged between the first clamping block and the limit block, and between the second clamping block and the limit block. The first clamping block and the second clamping block are both pressed against the plastic shell by the elastic force of the spring. When the battery cell positioning fixture is used, an external thrust is required to act on the spring, the first clamping block and the second clamping block to open the battery cell positioning fixture, and the external thrust is proportional to the elastic force of the spring.

[0004] However, when the battery cell positioning fixture is used on a magnetic levitation rail, the magnetic levitation rail is difficult to withstand a large external thrust. If the external thrust for opening the first clamping block and the second clamping block is too large, the magnetic levitation rail is easily damaged. Utility Model Content

[0005] In order to solve the shortcomings of the prior art, the utility model provides a tooling fixture for positioning plastic shell battery cells, which can be applied to a magnetic levitation guide rail. The external force of the opening and closing drive member to drive the first movable card plate to open and close is relatively stable, which is conducive to improving the situation where the magnetic levitation guide rail is damaged due to excessive external thrust.

[0006] The technical effects to be achieved by the utility model are achieved through the following technical aspects:

[0007] The utility model provides a tooling fixture for positioning a plastic shell battery cell, comprising a base plate, one side of which is provided with a loading plate; a fixed card plate group, which is arranged on the loading plate; and a movable card plate group, which is surrounded by the fixed card plate group to form a positioning area for clamping the plastic shell, the movable card plate group comprising a first movable card plate, the first movable card plate being transmission-connected to an opening and closing driving member for driving the first movable card plate to approach or move away from the positioning area.

[0008] In some implementations, a limiting plate is disposed on the bottom plate, a first elastic member is disposed between the limiting plate and the first movable card plate, and the first elastic member abuts against a corresponding side of the first movable card plate.

[0009] In some implementations, a connecting plate is provided on one side of the first movable card plate, and the connecting plate is transmission-connected to the opening and closing drive member; the movable card plate group includes a second movable card plate, and a follower component is provided between the second movable card plate and the connecting plate, and the connecting plate drives the second movable card plate to approach or move away from the positioning area via the follower component.

[0010] In some implementations, a linear guide rail is disposed on the connecting plate, a fixing seat is disposed on the loading plate, and the fixing seat is slidably connected to the linear guide rail.

[0011] In some implementations, the follower assembly includes an inclined block connected to the connecting plate; a follower wheel rollingly arranged on the inclined surface of the inclined block, the follower wheel being rotatably connected to the second movable pallet, and when the follower wheel rolls along the inclined surface of the inclined block, the second movable pallet approaches or moves away from the positioning area; and a limit member arranged between the second movable pallet and the loading plate and used to limit the moving direction of the second movable pallet.

[0012] In some implementations, a follower seat is provided between the follower wheel and the second movable card plate, the follower wheel is rotatably provided on the follower seat, and the first movable card plate is connected to the follower seat; a second elastic member is provided between the follower seat and the loading plate, and the second elastic member abuts against the corresponding side of the follower seat.

[0013] In some implementations, the limiting member includes a limiting seat, which is disposed at both ends of the follower seat in the moving direction; and a limiting rod, which is disposed between the limiting seats at both ends and passes through the follower seat, and the follower seat is slidably disposed on the limiting rod.

[0014] In some implementations, the inclined surface of the inclined block is an arc surface that matches the follower wheel.

[0015] In some implementations, a buffer block is disposed on the connecting plate, and the buffer block is located on a side of the loading plate away from the first movable card plate.

[0016] In some implementations, the fixed card plate group includes a first fixed card plate, which is arranged opposite to the first movable card plate; and a second fixed card plate, which is arranged opposite to the second movable card plate.

[0017] In summary, the utility model has at least the following benefits:

[0018] The utility model provides a tooling fixture for positioning plastic shell battery cells. The plastic shell is placed in a positioning area. When the opening and closing driving member drives the first movable card plate to approach the positioning area, the movable card plate group and the fixed card plate group cooperate to clamp the plastic shell. When the opening and closing driving member drives the first movable card plate away from the positioning area, the movable card plate group and the fixed card plate group open the clamps to facilitate the removal of the plastic shell material. Compared with the traditional battery cell positioning fixture, the opening and closing driving member provides a relatively stable external thrust for the movement of the first movable card plate, which can adapt to the use scenarios such as magnetic levitation guide rails, and improves the problem of damage to the magnetic levitation track due to excessive external thrust when opening the battery cell positioning fixture. At the same time, the relatively stable external thrust provided by the opening and closing driving member is conducive to improving the firmness of the clamping of the movable card plate group and the fixed card plate group, and reducing the possibility of the movable card plate group and the fixed card plate group over-clamping the plastic shell, causing the plastic shell to be squeezed and deformed.

[0031] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1:

[0034] Please refer to the attached Figure 1-3 The utility model discloses a fixture for positioning a plastic shell battery cell, comprising a base plate 1, one side of which is provided with a fixed card plate group 2 and a movable card plate group 3 for clamping and positioning a plastic shell 5.

[0035] Among them, a loading plate 11 is arranged on one side of the base plate 1, and the loading plate 11 is arranged parallel to the base plate 1. A connecting shaft 12 is arranged between the base plate 1 and the loading plate 11. Specifically, one end of the connecting shaft 12 along the axial direction is fixedly connected to the base plate 1, and the other end is fixedly connected to the loading plate 11.

[0036] The fixed card plate group 2 is arranged on the side of the loading plate 11 away from the bottom plate 1, and the fixed card plate group 2 includes a first fixed card plate 21 and a second fixed card plate 22. The first fixed card plate 21 and the second fixed card plate 22 are relatively vertically arranged. When the plastic shell 5 is in a clamped state, the first fixed card plate 21 and the second fixed card plate 22 respectively abut against the corresponding sides of the plastic shell 5 to position the plastic shell 5.

[0037] The movable card plate group 3 and the fixed card plate group 2 are surrounded to form a positioning area 23 for fixing and positioning the plastic shell 5. The movable card plate group 3 includes a first movable card plate 31, and the first movable card plate 31 is arranged opposite to the first fixed card plate 21. Specifically, the first movable card plate 31 includes a mounting section and a clamping section. The clamping section is in the shape of a long plate. A groove is provided on the side of the clamping section close to the positioning area 23. The first movable card plate 31 can reduce the possibility of extrusion deformation of the plastic shell 5 on the basis of ensuring the firmness of the clamping of the plastic shell 5. In some specific embodiments shown, the shapes of the first fixed card plate 21 and the second fixed card plate 22 are the same as the shape of the first movable card plate 31. It can be understood that this is not a specific limitation on the shape of the fixed card plate group 2, and technicians in the relevant field can replace it on this basis. The first movable card plate 31 is connected to the opening and closing drive member 32 in transmission connection. The opening and closing drive member 32 drives the first movable card plate 31 to approach or move away from the positioning area 23, and the first movable card plate 31 is slidably arranged on the bottom plate 1.

[0038] In a preferred embodiment, several groups of fixed card plate groups 2 are provided, and several fixed card plate groups 2 are arranged at intervals on the loading plate 11, and several groups of movable card plate groups 3 are correspondingly provided. The tooling fixture used for positioning the plastic shell battery cells can position multiple plastic shells 5 at the same time, which is conducive to improving work efficiency and saving occupied space.

[0039] When the opening and closing driving member 32 drives the first movable card plate 31 to approach the positioning area 23, the first movable card plate 31, the first fixed card plate 21 and the second fixed card plate 22 cooperate to clamp the plastic shell 5, and the plastic shell 5 is positioned. When the opening and closing driving member 32 drives the first movable card plate 31 away from the positioning area 23, the movable card plate group 3 and the fixed card plate group 2 are relatively far away from each other to be in an open state, and the operator takes out the plastic shell 5 material. The opening and closing driving member 32 provides a stable external thrust for the movement of the first movable card plate 31. Compared with the traditional battery cell positioning fixture, it can be applied to the magnetic suspension guide rail, which is conducive to improving the convenience, flexibility and work efficiency of use.

[0040] Embodiment 2:

[0041] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the first movable card plate 31 of the utility model, see Figure 2 and Figure 3 .

[0042] A connecting plate 33 is provided on one side of the first movable card plate 31 of the present embodiment. The connecting plate 33 is specifically a long plate and is located between the base plate 1 and the loading plate 11. The first movable card plate 31 is installed on the connecting plate 33. The connecting plate 33 is transmission-connected with the opening and closing driving member 32. When the opening and closing driving member 32 drives the connecting plate 33 to move, the connecting plate 33 is slidably set on the base plate 1.

[0043] In a preferred embodiment, the opening and closing driving member 32 preferably uses a single-acting cylinder, and a mounting groove is provided at one end of the connecting plate 33 away from the first movable card plate 31. The connecting plate 33 is drivingly connected with the piston rod end of the single-acting cylinder in the mounting groove. The single-acting cylinder drives the connecting plate 33 to move in the horizontal direction through the change of stroke, thereby driving the first movable card plate 31 to approach or move away from the positioning area 23. Specifically, a driving mounting seat is provided on the bottom plate 1, and the opening and closing driving member 32 is installed on the driving mounting seat.

[0044] In a preferred embodiment, a linear guide 332 is installed on the connecting plate 33, and the length direction of the linear guide 332 is consistent with the length direction of the connecting plate 33. A fixing seat 333 is installed on the side of the loading plate 11 close to the connecting plate 33, and the fixing seat 333 is slidably connected with the linear guide 332. When the opening and closing driving member 32 drives the connecting plate 33 and the linear guide 332 to move in the horizontal direction, the linear guide 332 guides and limits the movement of the connecting plate 33 through the fixing seat 333, which is conducive to improving the stability of the connecting plate 33 and the first movable clamping plate 31 during the movement process.

[0045] A buffer block 331 is installed on the connecting plate 33, and the buffer block 331 is located on the side of the loading plate 11 away from the first movable card plate 31. When the opening and closing driving member 32 drives the connecting plate 33 and the first movable card plate 31 away from the positioning area 23, the buffer block 331 moves with the connecting plate 33 to the fixed seat 333 until it collides with the fixed seat 333. The buffer block 331 can play a certain buffering role and limit the moving distance of the connecting plate 33.

[0046] In a preferred embodiment, a limiting plate 311 is provided on the side of the first movable card plate 31 away from the positioning area 23. The limiting plate 311 is specifically arranged vertically and is mounted on the bottom plate 1. A first elastic member 312 is provided on the side of the limiting plate 311 close to the first movable card plate 31. The first elastic member 312 is preferably, but not limited to, a spring. One end of the first elastic member 312 away from the limiting plate 311 abuts against the corresponding side of the first movable card plate 31. When the opening and closing driving member 32 drives the first movable card plate 31 away from the positioning area 23, the first movable card plate 31 squeezes the first elastic member 312. The first elastic member 312 acts as a buffer for the movement of the first movable card plate 31. When the opening and closing driving member 32 drives the first movable card plate 31 close to the positioning area 23, the first elastic member 312 acts through elastic force to increase the clamping force of the first movable card plate 31 on the plastic shell 5.

[0047] Embodiment 3:

[0048] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the mobile card group 3 of the utility model, see Figure 3 to Figure 6 .

[0049] The mobile card set 3 of this embodiment further includes a second mobile card 34, which is arranged opposite to the second fixed card 22, and is penetrated on the loading plate 11 and slidably arranged relative to the loading plate 11. A follower assembly 4 is arranged between the second mobile card 34 and the connecting plate 33, and the connecting plate 33 drives the second mobile card 34 to move away from or close to the positioning area 23 through the follower assembly 4, so as to cooperate with the second fixed card 22 to clamp and fix the plastic shell 5 in the vertical direction.

[0050] In a preferred embodiment, the follower assembly 4 includes an inclined block 41, which is mounted on the connecting plate 33. The inclined surface of the inclined block 41 is located at one end of the inclined block 41 away from the connecting plate 33. In some specific embodiments shown, the inclined surface of the inclined block 41 is an inclined arc surface. The inclined block 41 is provided with a follower wheel 42 at the inclined surface. The follower wheel 42 is rolled on the inclined surface and adapted to the inclined surface, which is conducive to improving the stability of the movement of the follower assembly 4. A follower seat 44 is provided on the side of the follower wheel 42 close to the loading plate 11. The follower wheel 42 is rotatably arranged on the follower seat 44. At this time, when the opening and closing driving member 32 drives the connecting plate 33 to move, the connecting plate 33 can drive the inclined block 41 to move in the horizontal direction. The inclined block 41 pushes the follower wheel 42 so that the follower wheel 42 can roll relative to the inclined block 41 along the inclined surface of the inclined block 41, thereby driving the follower seat 44 to adjust its position in the vertical direction. The follower seat 44 is connected to the second movable clamping plate 34 , thereby driving the second movable clamping plate 34 to move in the vertical direction to approach or move away from the positioning area 23 .

[0051] A stopper 43 is provided on one side of the follower seat 44 to limit the moving direction of the follower seat 44. In a preferred embodiment, the stopper 43 includes two stopper seats 431, which are respectively located at the two ends of the moving direction of the follower seat 44. The stopper seats 431 are installed on the side of the loading plate 11 close to the bottom plate 1. A stopper rod 432 is provided between the two stopper seats 431. Specifically, two stopper rods 432 are provided. It can be understood that the specific number of stopper rods 432 is not limited here, and technicians in the relevant field can replace them on this basis. The stopper rod 432 is penetrated on the follower seat 44. When the inclined block 41 pushes the follower wheel 42 to roll along the inclined surface, the follower seat 44 slides along the stopper rod 432. The stopper 43 plays a role in limiting and guiding the moving process of the follower seat 44 in the vertical direction. At the same time, the stopper seat 431 can limit the moving distance of the follower seat 44.

[0052] A second elastic member 45 is provided between the follower seat 44 and the limiting seat 431. The second elastic member 45 is preferably, but not limited to, a spring. When the opening and closing driving member 32 drives the connecting plate 33 to move in the horizontal direction, and the connecting plate 33 drives the second movable card plate 34 away from the positioning area 23, the connecting plate 33 drives the inclined block 41 to move in the horizontal direction at the same time. The inclined block 41 drives the follower seat 44 to move in the vertical direction through the follower wheel 42. The follower seat 44 slides on the limiting rod 432 and compresses the second elastic member 45. The second elastic member 45 plays a certain buffering role on the follower seat 44, and the follower seat 44 drives the second movable card plate 34 away from the positioning area 23. On the contrary, when the follower seat 44 drives the second movable card plate 34 to approach the positioning area 23, the second elastic member 45 acts through elastic force to increase the clamping force of the second movable card plate 34 on the plastic shell 5.

[0053] The opening and closing driving member 32 can realize the movement and adjustment of the first movable clamping plate 31 in the horizontal direction and the movement and adjustment of the second movable clamping plate 34 in the vertical direction through the follower component 4. It has a simple structure and is easy to operate, which is beneficial to improving the stability of the plastic shell 5 when clamped.
