The pushing mechanism 42 pushes the battery cells placed in one or two rows on the loading mechanism 41 to the bearing mechanism 43 to be arranged adjacently. After the bearing mechanism 43 is translated, the multiple battery cells located thereon are pushed by the stacking mechanism 45 until the battery cells at the end abut against the lifting and lowering material blocking mechanism 46 so that the multiple battery cells are closely abutted. After completing the above-mentioned stacking action, the battery cells in one or two rows that are closely abutted against each other can be bundled manually or mechanically to form a battery module and then unloaded. In the present invention, preferably two stacking units 4 are provided to cooperate with the material moving unit to improve the working efficiency of the equipment.

[0034] The utility model can complete the automatic stacking of battery cells through the stacking unit after the automatic loading (or posture adjustment) of the battery cells, realizes the automation of the whole process from a single battery cell to a battery cell module, and improves the efficiency of preparing the battery cell module.

[0035] Combination Figures 2 to 4As shown, in one embodiment of the utility model, the first material transfer mechanism 2 in the aforementioned process directly clamps a pair of battery cells and is clamped by the second material transfer mechanism 3 after being shaped for feeding, which is specifically as follows: the loading unit 1 also includes a transfer table 12, the transfer table 12 includes a support plate 121, a positioning plate 122 and a pair of push assemblies, the support plate 121 is arranged on the first frame 10, the positioning plate 122 is arranged on the support plate 121 and forms a right angle corner at one side for positioning one side of the battery cells, the pair of push assemblies are respectively a first push assembly 123 and a second push assembly 124 which are arranged perpendicularly to each other, when one When the first clamping cylinder 23 clamps a pair of battery cells and places them in a vertically spaced posture on the support plate 121, the first pushing assembly 123 first acts to push the pair of battery cells to abut against a right-angled side of the positioning plate 122 (at this time, there is still a gap between the narrow sides of the two battery cells), and the second pushing assembly 124 then acts to push the pair of battery cells to abut against another right-angled side of the positioning plate 122 (at this time, the two battery cells are abutted); after the posture of the pair of battery cells is adjusted, they can be moved by the clamping part 32 (in 32A state) in the second moving mechanism 3 to the stacking unit 4 to form a battery cell module with a double-row structure. For the posture adjustment of the battery cell, specifically, the first pushing cylinder 1231 in the first pushing assembly 123 drives the first pushing plate 1232 to approach the pair of battery cells 100, and the plurality of rotatable rollers 1233 arranged on the first pushing plate 1232 abut against the side walls of the pair of battery cells 100 and push the battery cell to abut against a right angle side of the right angle corner, and then the second pushing cylinder (not shown) in the second pushing assembly 124 drives the second pushing plate (not shown) to push the battery cell on one side to move and abut against the other battery cell until the other battery cell abuts against the other right angle side of the right angle corner, thereby achieving close abutment of the (narrow side) of the pair of battery cells, and due to the provision of the rollers 1 233 facilitates the lateral movement of the battery cells; after completing the above actions, in the second material transfer mechanism 3, the positioning member 321 of the clamping part 32 is set at the output end of the multi-axis manipulator 31 through the mounting plate 320, and a pair of second clamping cylinders 322 are provided on the positioning member 321. A pair of battery cells can be clamped by the pair of second clamping cylinders 322 and placed on the loading mechanism 41 on the stacking unit 4. A pair of long clamping plates 323 can also be provided at the clamping ends of the pair of second clamping cylinders 322 to abut against the pair of battery cells to ensure the stability of clamping and avoid damage to the battery cells. Since a pair of battery cells are placed in abutting double rows, a battery cell module with a double row structure can be formed in subsequent actions. In summary, in this process, the first material transfer mechanism 2 and the transfer table 12 cooperate to adjust the posture of a pair of battery cells (from the horizontal spacing posture to the vertical abutting posture), and then transport them through the second material transfer mechanism 3.

[0036] Combination Figure 2 and Figure 5As shown, in one embodiment of the present invention, the second material transfer mechanism 3 in the aforementioned process directly clamps a pair of battery cells for feeding, which is specifically as follows: the positioning member 321 in the second material transfer mechanism 3 may include a rotating motor 3210, a driving wheel 3211, a driven wheel 3212, a first guide rail pair 3214 and a pair of mounting blocks 3215, the driving wheel 3211 is arranged at the output end of the rotating motor 3210, the driven wheel 3212 is rotatably arranged on the mounting plate 320, and a transmission belt 3213 is sleeved on the outer side of the driving wheel 3211, the first guide rail pair 3214 is arranged on the mounting plate 320, a pair of mounting blocks 3215 are slidably arranged on the first guide rail pair 3214, and are axially symmetrically arranged on the transmission belt 3213, a rotating cylinder 3216 is arranged on the mounting block 3215, and the second clamping cylinder 322 is arranged at the output end of the rotating cylinder 3216, thereby forming two second clamping cylinders 3214 that can be flipped in a vertical plane. 2, the multi-axis manipulator 31 in the second material transfer mechanism 3 drives the clamping part 32 (in the state 32B) to directly clamp one battery cell on the feeding line 11, and a pair of short clamping plates 324 can be set on the clamping end of the second clamping cylinder 322 to abut against the battery cell to ensure the stability of clamping and avoid damage to the battery cell. After clamping, the narrow sides of a pair of battery cells are adjacent to each other, and the second clamping cylinder 322 is driven by the rotating cylinder 3216 to perform a 90° flip in the vertical plane, so that The wide sides of a pair of battery cells are spaced adjacent to each other, and then the rotating motor 3210 drives the driving wheel 3211, the driven wheel 3212 and the transmission belt 3213 to move, driving a pair of mounting blocks 3215 to move close to each other on the first guide rail pair 3214 so that the pair of battery cells are adjacent (the wide sides of the battery cells are adjacent), and are driven by a multi-axis manipulator to be placed on the loading mechanism 41, thereby forming a pair of battery cells that are placed in a single row front and back, and a battery cell module with a single row structure can be formed in subsequent actions. In summary, in this process, the functions of the first material transfer mechanism 2 and the transfer table 12 are omitted, and the process of adjusting the posture of a pair of battery cells is coordinated between the positioning member 321 and the second clamping cylinder 322 (adjusted from the posture of the narrow side spacing in the horizontal state on the feeding line 11 to the posture of the wide side adjacent in the vertical state after being placed on the loading mechanism 41).

[0037] In addition, the working positions of the first material moving mechanism 2 and the second material moving mechanism 3 can be set in the middle of the feeding line 11 (the transfer table 12 can also be set in the middle of the feeding line 11), so that a vacant position 11' can be formed at the end of the feeding line. When the first material moving mechanism 2 and the second material moving mechanism 3 fail to move materials in time, the missed battery cells can continue to be fed and manual unloading can be carried out at the vacant position 11'.

[0038] Combination Figures 6 to 9As shown, after the material transfer unit completes the above-mentioned cell placement action, stacking is performed through the stacking unit 4, specifically: the material loading mechanism 41 includes a mounting frame 410, a lifting cylinder 411, a material blocking assembly 412 and a carrying plate 413, the carrying plate 413 is arranged on the mounting frame 410 for carrying the cell, and a through gap 4130 is provided on the upper end surface, so that the cell is placed on the formed convex plate 4131, the material blocking assembly 412 is arranged at the output end of the lifting cylinder 411, and is driven to rise or The descent is used to block or open the connection between the supporting plate 413 and the supporting mechanism 43. When the battery cell is placed on the supporting plate 413, the blocking assembly 412 is driven by the lifting cylinder 411 to rise and be higher than the upper end surface of the convex plate 4131. Especially for a pair of battery cells arranged front and back in a single-row structure, the pair of battery cells can be abutted against each other through the pushing mechanism 42 after being blocked by the blocking assembly 412, and then the blocking assembly 412 is driven to descend to allow the battery cell to push the material onto the supporting mechanism 43.

[0039] Preferably, the material blocking assembly 412 includes a horizontal cylinder 4121 and a material blocking plate 4122. The horizontal cylinder 4121 is arranged at the output end of the lifting cylinder 411, and the material blocking plate 4122 is arranged at the output end of the horizontal cylinder 4121. When the battery cell is pushed onto the supporting mechanism 43, in order to avoid the material blocking assembly 412 from descending while in contact with the side wall of the battery cell, the material blocking plate 4122 can be driven by the horizontal cylinder 4121 to move a small distance and then disengage from the abutment with the side wall of the battery cell, and then driven downward by the lifting cylinder 411, thereby ensuring the position stability of the battery cell and avoiding damage to the outer wall of the battery cell.

[0040] The pushing mechanism 42 includes an electric cylinder 421 and a pushing assembly 422 arranged on the electric cylinder 421. The pushing assembly 422 includes a support plate 4221, a push plate 4223 and a lifting plate 4225. The support plate 4221 is arranged on the electric cylinder 421, and a vertical cylinder 4224 is arranged on its side wall. A push plate 4223 is arranged through a second guide rail pair 4222. The push plate 4223 is connected to the vertical cylinder 4224. A plurality of lifting plates 4225 are arranged at the lower end of the push plate 4223 and can extend into the through gap 4130. A pressing plate 4226 for abutting against the battery cell is arranged on the push plate 4223. 23 and the lifting plate 4225 are driven by the electric cylinder 421 until the pressing plate 4226 abuts against the battery cell (the other side of the battery cell is abutted by the blocking assembly 412) and remains stable. At this time, the lifting plate 4225 is located in the through gap 4130 and below the battery cell. After the blocking assembly 412 descends, the vertical cylinder 4224 drives the push plate 4223 and the lifting plate 4225 to rise until the lifting plate 4225 abuts against the lower end of the battery cell and lifts the battery cell off the supporting plate 413, and then is driven by the electric cylinder 421 until it is located above the supporting mechanism 43, and is reset by the vertical cylinder 4224 to place the battery cell on the supporting mechanism 43.

[0041] The supporting mechanism 43 includes a first motor 431 and a carrier 432. The carrier 432 is slidably arranged on the second frame 40 through a third guide rail pair 433, and is connected to the first motor 431 through a first screw nut pair 434. A plurality of bull's eye bearings 400 are arranged in a matrix shape on the carrier 432. A carrier plate (not shown) is rollingly supported on the bull's eye bearings 400. The carrier plate is used to carry the battery cells fed by the pushing mechanism 42 to the carrier 432 for translation. When a set number of battery cells are arranged in a single row or double rows on the carrier 432 (carrier plate), the first motor 431 drives the carrier 432 to translate on the third guide rail 433 through the first screw nut pair 434 until it is flush with the stacking mechanism 45. A blocking portion 44 can also be provided on the side of the second frame 40 away from the loading mechanism 41 to block the battery cells that are fed successively on the limiting carrier 432. In addition, since the platform 432 needs to be driven and translated, on the basis of having the third guide rail pair 433 support on one side, the other side can be supported by a roller 435 arranged on the second frame 40, thereby ensuring the stability of the support and translation of the platform 432.

[0042] The stacking mechanism 45 includes a second motor 451 and an L-shaped platform 452. The L-shaped platform 452 is slidably arranged on the second frame 40 through a fourth guide rail pair 453, and is connected to the second motor 451 through a second screw nut pair 454. A plurality of bull's eye bearings 400 are arranged in a matrix on the horizontal plate of the L-shaped platform 452, and the L-shaped platform 452 is driven to translate to the platform 432 next to it through the support of the bull's eye bearings 400. The L-shaped platform 452 has a clearance opening 450 for the platform 432 to translate to its upper part. The L-shaped platform 452 moves through its vertical plate to squeeze the battery cell onto the side wall of the lifting and lowering material blocking mechanism 46. When the platform 432 carrying the battery cells moves to be flush with the L-shaped platform 452, the side of the platform 432 away from the third guide rail pair 433 detaches from the roller 435 and moves to the top of the L-shaped platform 452, and is supported by the bull's eye bearing 400 on the L-shaped platform 452 for stable translation. When the platform 432 moves into place, the L-shaped platform 452 is driven by the second motor 451 to move toward the platform 432. Due to the support of the bull's eye bearing, the two can move in an upward and downward offset manner, and the vertical plate on the L-shaped platform 452 pushes the battery cells to abut tightly against each other and is limited by the lifting stop mechanism 46 on the other side, ultimately realizing the stacking molding of single-row or double-row battery cell modules.

[0043] More specifically, the lifting material blocking mechanism 46 includes a linear module 461, a side baffle 462 and a top plate 463. The linear module 461 is arranged on the second frame 40 through the side plate 460, and its output end is provided with a side baffle 462 for blocking the battery cell, that is, when it is necessary to cooperate with the stacking mechanism 45 to realize the stacking action of the battery cell, the linear module 461 drives the side baffle 462 to rise to block and limit the battery cell; the top plate 463 is arranged at the upper end of the side baffle 462, and the upper end thereof is provided with a plurality of matrix-shaped The bull's eye bearing 400 drives the top plate 463 downward to be flush with the carrier plate 432 that moves to its side. That is, after the stacking action is completed, the linear module 461 drives the side baffle 462 to drive the top plate 463 to descend to be flush with the carrier 432 (of course, the carrier 432 will not affect the descending action of the side baffle 462 and the top plate 463). In this way, the battery cell modules that have been stacked and bundled (with the help of the carrier plate at the lower end of the battery cell) can be easily unloaded through the bull's eye bearing 400 on the top plate 463.
