Description

Technical Field

[0001] This utility model relates to the field of lithium battery cell manufacturing technology, and in particular to a cell transfer mechanism. Background Technology

[0002] In the manufacturing process of lithium battery cells, cell transfer is often involved to move the cells to different production stations. For example, on existing stacking machines, after the positive electrode, separator, and negative electrode are stacked into a cell, they need to be transferred to the next station for processes such as adhesive bonding. However, some semi-automatic stacking machines require manual removal of the cells for transfer. This method is inefficient, labor-intensive for workers, and may cause cell deformation. Furthermore, some cell transfer fixtures have low integration, are not compact in design, and occupy a large amount of installation space. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a battery cell transfer mechanism with a compact structure, which saves installation space and improves the transfer efficiency of battery cells.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A battery cell transfer mechanism includes a vertical plate, a horizontal moving assembly, a rotating assembly, a vertical moving assembly, and a clamping assembly;

[0006] The horizontal moving component includes a horizontal sliding seat and a first driving source. The horizontal sliding seat is slidably disposed on the top of the vertical plate, and the first driving source is used to drive the horizontal sliding seat to slide along the X-axis on the vertical plate.

[0007] The rotating assembly includes a fixed base, a rotating disk, and a second drive source. The fixed base is mounted on a horizontal sliding base, and the rotating disk is rotatably positioned above the fixed base. The second drive source is used to drive the rotating disk to rotate in the XY plane.

[0008] The vertical movement component includes a support base, a vertical sliding base, and a third drive source. The support base is mounted on a rotary disk, the vertical sliding base is slidably disposed on the support base, and the third drive source is used to drive the vertical sliding base to slide along the Z-axis direction on the support base.

[0009] The clamping assembly is mounted on a vertical slide block and is used to clamp the battery cells.

[0010] In some embodiments, the rotating disk is polygonal, and each of the continuous multi-sided sidewalls of the rotating disk is provided with a sensing sheet; a sensor support is provided on the horizontal sliding seat outside the rotating disk, and a slotted photoelectric sensor matching the sensing sheet is provided on the sensor support.

[0011] In some embodiments, the cell transfer mechanism further includes a rotation limiting component, which includes a male limiting block, a first linear guide rail, a female limiting block, and a fourth drive source.

[0012] In at least one embodiment, the male limiting block is provided with triangular teeth, and the female limiting block is provided with triangular tooth grooves that match the male limiting block.

[0013] Compared with the prior art, this utility model achieves at least the following beneficial effects:

[0024] like Figures 1-5 As shown, a battery cell transfer mechanism includes a vertical plate 1, a horizontal moving assembly 2, a rotating assembly 3, a vertical moving assembly 4, and a clamping assembly 5, wherein:

[0025] The horizontal moving component 2 includes a horizontal sliding seat 21 and a first driving source 22. The horizontal sliding seat 21 is slidably disposed on the top of the vertical plate 1. The first driving source 22 is connected to the horizontal sliding seat 21 and is used to drive the horizontal sliding seat 21 to slide along the X-axis on the vertical plate 1.

[0026] The rotating assembly 3 includes a fixed base 31, a rotating disk 32, and a second drive source 33. The fixed base 31 is mounted on a horizontal sliding base 21, and the rotating disk 32 is rotatably positioned above the fixed base 31. The second drive source 33 is connected to the rotating disk 32 and is used to drive the rotating disk 32 to rotate in the XY plane.

[0027] The vertical moving component 4 includes a support base 41, a vertical sliding base 42 and a third drive source 43. The support base 41 is mounted on the rotary disk 32, the vertical sliding base 42 is slidably disposed on the support base 41, and the third drive source 43 is connected to the vertical sliding base 42 and is used to drive the vertical sliding base 42 to slide along the Z-axis on the support base 41.

[0028] The clamping assembly 5 is mounted on the vertical slide seat 42 and is used to clamp the battery cell 20.

[0029] The working principle of this utility model is as follows: This utility model is installed on a stacking machine and located on one side of the stacking table. After the positive electrode sheet, separator, and negative electrode sheet are stacked into a battery cell 20 on the stacking table, the first drive source 22 drives the horizontal sliding seat 21 to slide along the X-axis direction on the vertical plate 1, and the third drive source 43 drives the vertical sliding seat 42 to slide along the Z-axis direction on the support seat 41, thereby adjusting the left-right and up-down positions of the clamping assembly 5, so that the clamping assembly 5 can clamp the battery cell 20 from the stacking table. According to the next process of the battery cell 20, several battery cell stations 30 (such as adhesive application station, unloading station, etc.) are arranged radially above the rotating disk 32 with the center of the rotating disk 32 as the center. The second drive source 33 drives the rotating disk 32 to rotate in the XY plane, thereby adjusting the position of the clamped battery cell 20 in the XY plane, so that the clamped battery cell 20 can be transferred to the corresponding battery cell station 30 for the corresponding process.

[0030] In some embodiments of this utility model, the rotating disk 32 is polygonal, and each of its continuous multi-sided sidewalls is provided with a sensing plate 6; a sensor support 7 is provided on the horizontal sliding seat 21 outside the rotating disk 32, and a slotted photoelectric sensor 71 matching the sensing plate 6 is provided on the sensor support 7. It should be noted that when the rotating disk 32 rotates and brings the battery cell 20 clamped by the clamping assembly 5 to the corresponding battery cell station 30, the corresponding sensing plate 6 on the rotating disk 32 rotates into the slot of the slotted photoelectric sensor 71. At this time, the slotted photoelectric sensor 71 outputs a switch control signal to control the working state of the second drive source 33 and the clamping assembly 5. The rotating disk 32 stops rotating, the clamping assembly 5 releases the battery cell 20, and places the clamped battery cell 20 in the corresponding battery cell station 30.

[0031] In some embodiments of this utility model, the cell 20 transfer mechanism further includes a rotation limiting component 8. The rotation limiting component 8 includes a male limiting block 81, a first linear guide rail 82, a female limiting block 83, and a fourth driving source 84. The male limiting block 81 is mounted on the side wall of the rotating disk 32. The first linear guide rail 82 is mounted on the horizontal sliding seat 21 along the Y-axis direction. The female limiting block 83 is mounted on the slider of the first linear guide rail 82. The fourth driving source 84 is used to drive the female limiting block 83 to slide along the Y-axis direction on the first linear guide rail 82.

[0032] Furthermore, the male limit block 81 is provided with triangular teeth, and the female limit block 83 is provided with triangular tooth grooves that match the male limit block 81. It should be noted that when the rotating disk 32 rotates to the set angle, that is, when the clamping assembly 5 rotates to the special cell station 30, the male limit block 81 and the female limit block 83 are opposite each other. At this time, the fourth drive source 84 drives the female limit block 83 to slide along the Y-axis and approach the male limit block 81, and the triangular teeth are pressed into the triangular tooth grooves, thereby limiting the rotation of the rotating disk 32.

[0033] Furthermore, the fourth drive source 84 is a cylinder, and the piston rod of the fourth drive source 84 is fixedly connected to the female limiting block 83 through a connecting plate.

[0034] In addition, a second linear guide rail 9 is provided on the top of the upright plate 1 along the X-axis direction, and a horizontal sliding seat 21 is mounted on the slider of the second linear guide rail 9; a third linear guide rail 10 is provided on the support base 41 along the Z-axis direction, and a vertical sliding seat 42 is mounted on the slider of the third linear guide rail 10. The second linear guide rail 9 and the third linear guide rail 10 can respectively ensure the movement accuracy of the horizontal sliding seat 21 and the vertical sliding seat 42.

[0035] The first drive source 22 includes a first stepper motor 221, a first reducer 222, and a synchronous pulley assembly 223 connected by transmission. The first stepper motor 221, the first reducer 222, and the synchronous pulley assembly 223 are located below the horizontal sliding seat 21. The synchronous belt of the synchronous pulley assembly 223 is fixedly connected to the horizontal sliding seat 21 through a pressure block. When the synchronous belt moves, it is used to drive the horizontal sliding seat 21 to slide along the X-axis on the vertical plate 1.

[0036] The second drive source 33 includes a second stepper motor 331 and a second reducer 332 connected by transmission. The second stepper motor 331 and the second reducer 332 are located below the fixed base 31, and the output shaft of the second reducer is connected to the rotating disk 32.

[0037] The third drive source 43 is a cylinder, which is mounted on the support base 41, and its piston rod is fixedly connected to the vertical sliding base 42.

[0038] The clamping assembly 5 includes a parallel pneumatic gripper 51 and a clamping fixture 52. The clamping fixture 52 is mounted on the two pneumatic grippers of the parallel pneumatic gripper 51. The clamping fixture 52 includes a mounting plate 521 and a clamping finger 522. The mounting plate 521 has a waist-shaped hole 5211. The clamping finger 522 is connected to the waist-shaped hole 5211 of the mounting plate 521 by screws. The clamping finger 522 is used to clamp the battery cell 20.

[0039] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
