Description

Technical Field

[0001] This utility model relates to the field of adjusting the position of battery cells, and more particularly to a positioning device. Background Technology

[0002] like Figure 1 As shown, Figure 1 The existing battery cell clamp has a single-row symmetrical clamping section. The battery cell is transported into the battery cell clamp by a transfer mechanism and clamped by the clamping section.

[0003] The battery cells need to be recalibrated before being transferred to the cell clamp by the transfer mechanism. However, the spacing between the clamping parts is relatively small, making adjustment difficult. Therefore, the adjustment of the battery cells not only needs to maintain a small spacing, but also needs to be aligned. Existing positioning mechanisms cannot adjust the positions of multiple closely spaced battery cells. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a positioning mechanism capable of locating multiple closely adjacent battery cells, thereby rapidly improving production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a positioning device, characterized in that it includes a platform portion carrying a battery cell fixture, and a transfer mechanism for extracting the battery cell from the positioning mechanism onto the battery cell fixture. The positioning mechanism includes a worktable and a movable plate and a positioning plate disposed on the worktable. The movable plate is disposed on the positioning plate, and the movable plate has an end extending to the surface of the worktable, which is slidably connected to the worktable. A positioning protrusion on the positioning plate and the side of the movable plate form a positioning area for constraining the battery cell. Within the positioning area, multiple movable positioning components divide the positioning area into multiple locking positions.

[0006] Furthermore, the positioning component is a push plate, and the worktable has openings at both ends extending towards the battery cell. The push plate is located inside the openings, and the other part is located on the worktable, forming a positioning area together with the movable plate and the positioning protrusion.

[0007] Furthermore, it also includes a first push cylinder and a connecting plate disposed below the worktable, with multiple push plates disposed on the connecting plate, and the output end of the first push cylinder connected to the connecting plate.

[0008] Furthermore, it also includes a second push cylinder mounted on the worktable, the output end of which is connected to the movable plate.

[0009] Furthermore, the transfer mechanism includes a linear moving component, an adsorption component, and a contact release component that opens the clamping portion. The adsorption component and the contact release component are connected to the output end of the linear moving component. A set of adsorption components is provided and located on both sides of the contact release component.

[0010] Furthermore, the contact release assembly includes a pressure plate with multiple pressure blocks extending from it, the pressure blocks being opposite to the clamping portion.

[0011] Furthermore, the platform is equipped with a rotating mechanism, and the output end of the rotating mechanism is connected to a rotating plate that supports the battery cell fixture.

[0012] Furthermore, a support member is provided between the platform and the positioning device, and a pulley is provided on the top of the support member, with the rotating plate mounted on the pulley.

[0013] The beneficial effects of this utility model are:

[0014] The positioning device provided by this utility model has pre-set slots for positioning multiple battery cells. The positioning protrusion and the movable plate apply pressure to the side of the battery cell along the length direction, so that the position of the battery cell is adjusted to a certain extent in the predetermined position and direction. By the positioning component applying pressure to the side of the battery cell along the width in the positioning area, multiple battery cells are finally positioned in the predetermined position. Combined with the transfer mechanism, the positioned battery cells are placed into the battery cell fixture. Thus, multiple closely adjacent battery cells are positioned. Attached Figure Description

[0024] like Figure 2-9 As shown, Figure 2 The positioning device is specifically designed for the clamping portion 81 in this single-row symmetrical layout.

[0025] The positioning device includes a platform 1 that carries a battery cell fixture 8, and a transfer mechanism 2 that pulls the battery cell 7 from the positioning mechanism onto the battery cell fixture 8. The positioning mechanism includes a worktable 3 and a movable plate 4 and a positioning plate 5 disposed on the worktable 3. The movable plate 4 is disposed on the positioning plate 5 and has an end that extends to the surface of the worktable 3. The end is slidably connected to the worktable 3 (in an embodiment, the end is connected to a sliding mechanism on the surface of the worktable 3). A positioning protrusion 51 provided on the positioning plate 5 forms a positioning area 6 for constraining the battery cell 7 between it and the side of the movable plate 4. Within the positioning area 6, there are multiple movable positioning components that divide the positioning area 6 into multiple locking positions.

[0026] The positioning device provided by this utility model has pre-set slots for positioning multiple battery cells 7. The positioning protrusion 51 and the movable plate 4 apply pressure to the side of the battery cell 7 along the length direction, so that the position of the battery cell 7 is adjusted to a certain extent in the predetermined position and direction. By the positioning component applying pressure to the side of the battery cell 7 along the width in the positioning area 6, multiple battery cells 7 are finally positioned in the predetermined position. Combined with the transfer mechanism 2, the positioned battery cells 7 are placed into the battery cell fixture 8. Thus, multiple closely adjacent battery cells 7 are positioned.

[0027] In other words, this utility model applies pressure to the circumferential surface of the battery cell 7, uses the movable plate 4 and the positioning protrusion 51 to determine the adjustment of the battery cell 7 in one direction, and then uses the movable positioning component in the positioning area 6 to adjust the battery cell 7 in another direction, thereby achieving the purpose of adjusting the position of the battery cell 7.

[0028] Furthermore, the positioning component is a push plate 9. The worktable 3 has openings at both ends extending towards the battery cell 7. Part of the push plate 9 is located inside the opening, and the other part is located on the worktable 3. Together with the movable plate 4 and the positioning protrusion 51, it forms a positioning area 6. The opening serves as a guide to ensure that the movement direction of the push plate 9 does not deviate from its original trajectory, thereby enhancing the stability of use.

[0029] Furthermore, it also includes a first push cylinder 10 and a connecting plate 11 located below the worktable 3, with multiple push plates 9 mounted on the connecting plate 11, and the output end of the first push cylinder 10 connected to the connecting plate 11; using a cylinder drive method can save a lot of usage time, and at the same time, a single connecting plate 11 drives multiple push plates 9 to move, so the number of power sources required is relatively small, requiring only one cylinder to push.

[0030] Furthermore, it also includes a second push cylinder 12 installed on the workbench 3. The output end of the second push cylinder 12 is connected to the movable plate 4. The second push cylinder 12 serves as the power source for moving the movable plate 4, which also plays a role in improving efficiency.

[0031] Furthermore, the transfer mechanism 2 includes a linear moving component 21, an adsorption component 22, and a contact release component for opening the clamping portion 81. The adsorption component 22 and the contact release component are connected to the output end of the linear moving component 21. There is one set of adsorption components 22, which are located on both sides of the contact release component. The transfer mechanism 2 is a separate design based on the current cell clamp 8. The positions for placing the cell 7 on the cell clamp 8 are located on both sides of the clamping portion 81. The contact release component is located between the two adsorption components 22 and can smoothly transfer the position of the cell 7 to the cell clamp 8. Each set of adsorption components 22 has multiple adsorption heads 22d. The adsorption heads 22d between the sets are staggered to meet the symmetrical layout of the single-row clamping portion 81.

[0032] Furthermore, the contact release assembly includes a pressure plate 23 and a plurality of pressure blocks 24 extending from the pressure plate 23. The pressure blocks 24 are opposite to the clamping portion 81. The pressure blocks 24 apply pressure to the clamping portion 81 through contact, causing the clamping portion 81 to open. The advantage of this method is that the clamping portion 81 can be opened completely at once, and the opening and closing angles of the clamping portion 81 can be controlled synchronously.

[0033] In this embodiment, a lifting mechanism is also provided at the output end of the linear motion component 21 to separately control the lifting and lowering of the pressure plate 23.

[0034] Furthermore, the table section 1 is provided with a rotating mechanism, the output end of which is connected to a rotating plate 81 that supports the battery cell fixture 8, for transferring the battery cell fixture 8 to other workstations.

[0035] Furthermore, a support member 100 is provided between the platform part 1 and the positioning device. The top of the support member 100 is provided with a pulley, and the rotating plate 81 is mounted on the pulley. When the pressure block 24 opens the clamping part 81, the support member 100 can support the pressure brought by the pressure block 24 and improve the service life of the rotating plate.

[0036] It should be noted that, due to the small spacing between the clamping parts 81, the spacing between the adsorption heads 22d needs to be adjusted. The adsorption assembly 22 also includes a mounting plate 22a, positioning sliders, an adsorption cylinder 22b, and adjusting screws. The mounting plate 22a is provided with a slide rail 22c, and the positioning sliders are slidably connected to the slide rail 22c. In this embodiment, there are four positioning sliders, and the adsorption heads 22d are respectively disposed on the positioning sliders. The positioning sliders are connected to each other by adjusting screws. Specifically, the first adjusting screw 22f on the first positioning slider 22e is threadedly connected to the second positioning slider 22g. The first adjusting screw 22f does not penetrate the second positioning slider 22g. Similarly, the second positioning slider 22g, the third positioning slider 22h, and the fourth positioning slider 22i are also connected in the same way. The suction cylinder 22b is connected to the first positioning slider 22e on the edge. When the suction cylinder 22b pulls the first positioning slider 22e to move towards the center of the side of the mounting plate 22a, the first adjusting screw 22f first moves into the threaded hole on the second positioning slider 22g by rotation, bringing it closer to the second positioning slider 22g. When the first adjusting screw 22f reaches the end of the threaded hole of the second positioning slider 22g, it pushes the second positioning slider 22g in a pushing manner, causing the second adjusting screw 22j on the second positioning slider 22g to move into the third positioning slider 22h in the same manner. The other positioning sliders move according to the same principle, so they will not be described in detail.

[0037] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
