[0002] During the production process of battery cells, unloading of battery cells is an important step. When unloading battery cells, a clamping assembly is required to clamp the battery cells. As the size of the battery cells gradually increases, when the diameter of the battery cells is larger, the gravity of the battery cells also increases. During the unloading process, the battery cells are prone to drooping and deformation. Moreover, the movements of the upper and lower clamping needles of the existing battery cell unloading mechanism are controlled separately, which is not only inconvenient for maintenance, but also may cause core pulling.

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] Reference Figure 1As shown, the multi-pin feeding mechanism feeds the battery cell 100 from the winding needle 101, the first direction is parallel to the axial direction of the battery cell 100, the second direction is perpendicular to the first direction in the horizontal plane, and the third direction is arranged along the longitudinal direction perpendicular to the horizontal plane. The first direction, the second direction, and the third direction constitute a spatial rectangular coordinate system.

[0031] The multi-needle blanking mechanism described in the utility model includes: a reference platform 1, a notch is provided in the middle position of the reference platform 1; a longitudinal support frame 2, which is vertically arranged in the notch of the reference platform 1, and the longitudinal support frame 2 reciprocates on the reference platform 1 along a first direction; third linear guide rails 12 are provided on both sides of the notch of the reference platform 1, and the longitudinal support frame 2 is slidably connected to the third linear guide rails 12 on both sides along a second direction; the longitudinal support frame 2 is controlled by a first driving mechanism 13 arranged at the bottom of the reference platform 1, and reciprocates along the third linear guide rail 12, wherein the first driving mechanism 13 includes a first servo motor 131 and a first screw rod 132, the output shaft of the first servo motor 131 is connected to the first screw rod 132, and the longitudinal support frame 2 is connected to the first screw rod 132 through a sliding connecting seat. The upper and lower unloading clamping needle mechanism 3 is arranged on the longitudinal support frame 2 and can move up and down on the longitudinal support frame 2 along the third direction, and is used to clamp the upper and lower side walls of the battery cell 100 respectively; the left and right unloading clamping needle mechanism 4 is arranged in the reference platform 1 and is located on both sides of the longitudinal support frame 2, and is used to clamp the left and right side walls of the battery cell 100. The longitudinal support frame 2 is provided with a fourth linear guide rail 21, and the upper and lower unloading clamping needle mechanism 3 is slidably connected to the fourth linear guide rail 21.

[0032] like Figure 2 As shown, the upper and lower unloading needle clamping mechanism 3 includes an upper clamping assembly 31, a lower clamping assembly 32 and a second driving mechanism 33. The upper clamping assembly 31 and the lower clamping assembly 32 are both slidably arranged on the longitudinal support frame 2. The upper clamping assembly 31 and the lower clamping assembly 32 are synchronously driven by the second driving mechanism 33 arranged on the longitudinal support frame 2 to move in opposite directions. Since the upper clamping assembly 31 and the lower clamping assembly 32 can be driven by the second driving mechanism 33 to synchronously expand or contract up and down along the fourth linear guide rail 21, good synchronization is maintained. When the battery cell 100 is clamped, the battery cell 100 can be clamped more firmly and is not easy to slip.

[0033] Preferably, the second driving mechanism 33 comprises a second servo motor 331, a second screw rod 332 and a third screw rod 333. The second screw rod 332 and the third screw rod 333 have opposite thread directions and are connected by a connecting piece. The output shaft of the second servo motor 331 is connected to the second screw rod 332. The upper clamping assembly 31 is connected to the second screw rod 332, and the lower clamping assembly 32 is connected to the third screw rod 333. The second servo motor 331 is started to control the second screw rod 332 and the third screw rod 333 to rotate synchronously. Since the thread directions of the two screw rods are opposite, when the second screw rod 332 and the third screw rod 333 rotate, the upper clamping assembly 31 and the lower clamping assembly 32 always move in opposite directions.

[0034] The structures of the upper clamping assembly 31 and the lower clamping assembly 32 both include a sliding block 311, a fixed clamping jaw 312, a movable clamping jaw 313 and a first clamping jaw cylinder 314. The fixed clamping jaw 312 and the first clamping jaw cylinder 314 are both mounted on the sliding block 311, and the telescopic rod of the first clamping jaw cylinder 314 is connected to the movable clamping jaw 313. The sliding blocks 311 of the upper clamping assembly 31 and the lower clamping assembly 32 move up and down along the second screw rod 332 and the third screw rod 333 respectively, so that the upper clamping assembly 31 and the lower clamping assembly 32 are close to or away from the upper side wall and the lower side wall of the battery cell 100, and the first clamping jaw cylinder 314 drives the movable clamping jaw 313 to move in the vertical direction to realize the opening and closing action with the fixed clamping jaw 312.

[0035] like Figure 3 As shown, the left and right unloading needle clamping mechanism 4 includes a left clamping assembly 41 and a right clamping assembly 42 symmetrically arranged on both sides of the notch, and the left clamping assembly 41 and the right clamping assembly 42 are respectively driven and controlled by a separate third driving mechanism 43 to achieve horizontal position movement. The left clamping assembly 41 and the right clamping assembly 42 are respectively controlled by separate driving mechanisms, which can make it more convenient to adjust the left and right centering of the left and right clamping assembly 41 and the right clamping assembly 42.

[0036] Preferably, the third driving mechanism 43 includes an X-axis linear driving module and a Y-axis linear driving module, the X-axis linear driving module includes a third servo motor 431, a fourth screw rod 432 and an X-axis sliding plate 433, the output end of the third servo motor 431 is connected to the fourth screw rod 432, and the X-axis sliding plate 433 is connected to the fourth screw rod 432; the Y-axis linear driving module includes a fourth servo motor 434, a fifth screw rod 435 and a synchronous pulley assembly 436, the fourth servo motor 434 and the fifth screw rod 435 are arranged on the X-axis sliding plate 433, and the output shaft of the fourth servo motor 434 is connected to one end of the fifth screw rod 435 through the synchronous pulley assembly 436. In this embodiment, the fourth servo motor 434 and the fifth screw rod 435 are arranged on both sides of the X-axis sliding plate 433 and are connected through the synchronous pulley assembly 436 to improve space utilization. In other embodiments, the fourth servo motor 434 can also be directly connected to the fifth screw rod 435. The reference platform 1 is also provided with first linear guide rails 11 on both sides of the X-axis linear drive module, and the X-axis sliding plate 433 is slidably connected to the first linear guide rails 11. The X-axis linear drive module can realize position adjustment in the first direction, and the Y-axis linear drive module can realize position adjustment in the second direction. The X-axis linear drive module and the Y-axis linear drive module work together. In the actual operation process of clamping the battery cell 100, the positions of the left clamping component 41 and the right clamping component 42 in the first direction and the second direction are adjusted, so that the left clamping component 41 and the right clamping component 42 clamp the battery cell 100 from both sides, and control the left clamping component 41 and the right clamping component 42 to extend into the battery cell 100 to maintain a suitable distance to avoid clamping or slipping. At the same time, the distance between the left clamping component 41 and the right clamping component 42 can be adjusted according to the size of the battery cell 100.

[0037] like Figure 4As shown, the left clamping assembly 41 and the right clamping assembly 42 have the same structure, and both include an inner clamping jaw 411, an elastic outer clamping jaw 412, a second clamping jaw cylinder 413 and a clamping jaw connecting seat 414. The clamping jaw connecting seat 414 is connected to the fifth screw rod 435 of the Y-axis linear drive module. The second clamping jaw cylinder 413 is arranged on the clamping jaw connecting seat 414. The telescopic rod of the second clamping jaw cylinder 413 is connected to the elastic outer clamping jaw 412. The inner clamping jaw 411 is arranged on the clamping jaw connecting seat 414 and is arranged opposite to the elastic outer clamping jaw 412. The X-axis sliding plate 433 is also provided with a second linear guide rail 437, and the clamping jaw connecting seat 414 is slidably connected to the second linear guide rail 437. The elastic outer clamp 412 is controlled by the second clamp cylinder 413 to move closer to or further away from the inner clamp 411. When the elastic outer clamp 412 and the inner clamp 411 are close to clamping the battery cell 100, the elasticity of the elastic outer clamp 412 makes the clamping force of the left clamping component 41 and the right clamping component 42 better, which can ensure that the battery cell 100 is clamped while avoiding deformation of the outer clamp and avoiding the battery cell 100 from being injured.

[0038] like Figure 5 , 6 7 and 7 show schematic diagrams of the multi-pin clamping blanking mechanism of the present invention clamping the battery cell 100 from the upper and lower side walls and the left and right side walls.

[0039] The battery cell 100 is wound on the winding needle 101 , and the outer surface of the winding needle 101 is provided with a plurality of avoidance grooves 1011 for the blanking clamping needle to extend into.

[0040] In the initial state, the first drive mechanism 13 and the X-axis linear drive module are both in the retracted position, and the upper and lower unloading clamping needle mechanisms 3 and the left and right unloading clamping needle mechanisms 4 are both away from the winding needle 101 along the axial direction of the winding needle 101; the first clamping jaw cylinders 314 of the upper clamping assembly 31 and the lower clamping assembly 32 are respectively in the retracted position, so that the movable clamping jaw 313 is away from the fixed clamping jaw 312, forming a clamping gap larger than the wall thickness of the battery cell 100; the second clamping jaw cylinders 413 of the left clamping assembly 41 and the right clamping assembly 42 are respectively in the retracted position, so that the elastic outer clamping jaw 412 is away from the inner clamping jaw 411, forming a clamping gap larger than the wall thickness of the battery cell 100.

[0041] According to the actual size of the battery cell 100, the positions of the upper clamping assembly 31, the lower clamping assembly 32, the left clamping assembly 41, and the right clamping assembly 42 are adjusted: the second driving mechanism 33 drives the upper clamping assembly 31 and the lower clamping assembly 32 to move away from each other to the set positions, and the Y-axis linear driving modules of the left clamping assembly 41 and the right clamping assembly 42 respectively drive the left clamping assembly 41 and the right clamping assembly 42 to move away from each other to the set positions.

[0042] The first drive mechanism 13 and the X-axis linear drive module are both in the extended position, the upper and lower unloading clamping needle mechanisms 3 and the left and right unloading clamping needle mechanisms 4 are close to the battery cell 100, the fixed clamping jaws 312 of the upper clamping assembly 31 and the lower clamping assembly 32 extend into the avoidance groove 1011 of the winding needle 101, the movable clamping jaws 313 of the upper clamping assembly 31 and the lower clamping assembly 32 are located on the outside of the battery cell 100, the inner clamping jaws 411 of the left clamping assembly 41 and the right clamping assembly 42 extend into the avoidance groove 1011 of the winding needle 101, and the elastic outer clamping jaws 412 of the left clamping assembly 41 and the right clamping assembly 42 are located on the outside of the battery cell 100.

[0043] The first clamping jaw cylinders 314 of the upper clamping assembly 31 and the lower clamping assembly 32 are respectively in the extended position, so that the movable clamping jaw 313 is close to the fixed clamping jaw 312 to clamp the upper and lower side walls of the battery cell 100; the second clamping jaw cylinders 413 of the left clamping assembly 41 and the right clamping assembly 42 are respectively in the extended position, so that the elastic outer clamping jaw 412 is close to the inner clamping jaw 411 to clamp the left and right side walls of the battery cell 100.

[0044] The first driving mechanism 13 and the X-axis linear driving module are in the retracted position again, and the upper and lower unloading clamping needle mechanisms 3 and the left and right unloading clamping needle mechanisms 4 unload the battery cell 100 from the winding needle 101. The unloading of the battery cell 100 is completed.

[0045] The upper and lower unloading clamping needle mechanisms 3 and the left and right unloading clamping needle mechanisms 4 extend into the avoidance groove 1011 of the winding needle 101 to synchronously clamp and remove the battery cell 100, and can synchronously release the clamped battery cell 100, which can effectively reduce the wrinkling of the diaphragm of the battery cell 100; and the upper clamping component 31 and the lower clamping component 32 of the upper and lower unloading clamping needle mechanisms 3 can be driven by the same driving component to move relative to each other, saving driving components and achieving better synchronization effect.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
