Description

[0002] Winding and lamination are the core links of the lithium battery mid-cell assembly process and are two different battery cell manufacturing processes. Winding is a production process that rolls the pole pieces, diaphragms, and termination tapes that match the size of the strips into pole cores. Lamination is a production process that alternately stacks the pole pieces and diaphragms together to finally complete a multi-layer laminated pole core. For Z-shaped laminated lithium batteries, the diaphragm is in a continuous Z shape, and the pole pieces are placed between the two layers of diaphragms.

DETAILED DESCRIPTION

[0040] The present invention will be further described below in conjunction with the accompanying drawings:

[0041] like Figure 1 As shown, a high-efficiency electrode stacking device includes a feeding mechanism 1, a stacking mechanism 2, a gluing mechanism 3 and a transfer mechanism 4. The stacking mechanism 2 is fixedly arranged downstream of the feeding mechanism 1, and the transfer mechanism 4 is fixedly arranged between the stacking mechanism 2 and the gluing mechanism 3.

[0042] The loading mechanism 1 transports the electrode to the stacking mechanism 2, and performs Z-shaped stacking with the diaphragm on the stacking mechanism 2. The semi-finished product after stacking is transported to the gluing mechanism 3 through the transfer mechanism 4. The gluing mechanism 3 performs a gluing process on all sides of the semi-finished product, and then transfers it to the transfer mechanism 4, which unloads it.

[0043] like Figures 2 to 6 As shown, the feeding mechanism 1 includes a first mounting platform 11, a mounting stand 12, a first X-axis drive assembly 13, a feeding manipulator 14, a handling manipulator 15, a feeding platform 16 and a positioning platform 17. The mounting stand 12 is vertically fixed above the first mounting platform 11, the first X-axis drive assembly 13 is fixed to the upper end of the mounting stand 12, the feeding manipulator 14 and the handling manipulator 15 are respectively fixed to the power output ends on the left and right sides of the first X-axis drive assembly 13, and the feeding platform 16 and the positioning platform 17 are both fixed on the first mounting platform 11 and correspond to the lower parts of the feeding manipulator 14 and the handling manipulator 15 respectively;

[0044] The loading robot 14 includes a first Z-axis drive assembly 141, a lifting vertical plate 142, a fixed horizontal plate 143, a bending plate 144, a bending cylinder 145, a suction cup mounting frame 146 and a suction cup assembly 147. The first Z-axis drive assembly 141 is fixed to the power output end of the first X-axis drive assembly 13, the lifting vertical plate 142 is fixed to the power output end of the first Z-axis drive assembly 141, the fixed horizontal plate 143 is fixed to the lower end of the lifting vertical plate 142, the rear end of the bending plate 144 is hinged to the front end of the fixed horizontal plate 143, the rear end of the bending cylinder 145 corresponds to the top of the fixed horizontal plate 143 and is hinged to the lifting vertical plate 142, the front end of the bending cylinder 145 is the power output end and is hinged to the bending plate 144, the suction cup mounting frame 146 is provided with two groups and is respectively fixed on the fixed horizontal plate 143 and the bending plate 144, and the suction cup assembly 147 is fixed to the left and right ends of the suction cup mounting frame 146.

[0045] The neatly stacked pole pieces are placed on the loading platform 16, and are sucked up one by one by the loading robot 14 and moved to the positioning platform 17 for positioning. The transport robot 15 transports the pole pieces on the positioning platform 17 to the post-process. When the loading robot 14 grabs the pole pieces, the first X-axis drive assembly 13 drives the loading robot 14 to move above the loading platform 16. Then, the first Z-axis drive assembly 141 drives the lifting plate 142 to descend, so that the suction cup assembly 147 adsorbs the top pole piece. Then, the lifting plate 142 rises, and the bending cylinder 145 drives the bending plate 144 to fold downward at a certain angle, thereby bending the pole piece. If there are other pole pieces attached to the bottom of the top pole piece, as the pole piece bends, the other pole pieces will fall off, thereby ensuring that the loading robot 14 only transports one pole piece at a time. After the bending plate 144 is folded and reset, the loading robot 14 can transport the pole piece to the positioning platform 17. The advantage of this design is that it can prevent the electrodes from overlapping during the material removal process, ensuring that only one electrode is transported each time, thereby ensuring the stability of subsequent processing.

[0046] The first X-axis drive assembly 13, the loading manipulator 14, the handling manipulator 15, the loading platform 16 and the positioning platform 17 are arranged in two groups symmetrically with respect to the mounting stand 12. Two groups of pole pieces can be transported at the same time, which is convenient for the efficient implementation of the subsequent lamination process.

[0047] The first Z-axis driving assembly 141 includes a fixed vertical plate 1411, a Z-axis slide 1412, a first Z-axis cylinder 1413 and a Z-axis slider 1414. The fixed vertical plate 1411 is fixed to the power output end of the first X-axis driving assembly 13. The Z-axis slide 1412 and the first Z-axis cylinder 1413 are both fixed on the fixed vertical plate 1411. The lifting vertical plate 142 is fixed to the power output end of the first Z-axis cylinder 1413. The Z-axis slider 1414 is fixed to the upper end of the lifting vertical plate 142 and is slidably connected to the Z-axis slide 1412.

[0048] The first Z-axis driving assembly 141 drives the lifting stand 142 to slide along the vertical direction on the Z-axis slide 1412 .

[0049] The loading platform 16 includes a material frame 161, a second Z-axis drive component 162, a loading platform 163 and a pole piece brush 164. The material frame 161 is fixed above the first mounting platform 11 and corresponds to the bottom of the loading robot 14. A loading cavity 1611 is provided in the material frame 161. The second Z-axis drive component 162 is fixed on the first mounting platform 11. The loading platform 163 is fixed at the power output end of the second Z-axis drive component 162 and corresponds to the loading cavity 1611. The pole piece brush 164 is fixedly arranged and corresponds to the top of the loading platform 163. The pole piece brush 164 is arranged in multiple groups and corresponds to the front and rear sides of the loading platform 163. The brush end of the pole piece brush 164 corresponds to the edge of the loading cavity 1611.

[0050] The neatly stacked pole pieces are placed in the loading cavity 1611. As the pole pieces are continuously removed, the second Z-axis drive assembly 162 gradually lifts the loading platform 163 to facilitate the loading robot 14 to pick up the material. When the loading robot 14 grabs the pole piece and rises, the edge of the pole piece contacts the pole piece brush 164. If there are other pole pieces attached to the bottom of the topmost pole piece, they will be scraped off by the pole piece brush 164, further ensuring that the loading robot 14 only grabs one pole piece.

[0051] The positioning platform 17 includes a first mounting bracket 171, a second mounting bracket 172, a positioning platform 173, a second Z-axis cylinder 174, a driving block 175 and a first positioning assembly 176. The first mounting bracket 171 is fixed above the first mounting platform 11, the positioning platform 173 is fixed above the first mounting bracket 171, the second mounting bracket 172 is fixed below the positioning platform 173, the second Z-axis cylinder 174 is fixed on the second mounting bracket 172 with the power output end facing upward, the driving block 175 is fixed at the power output end of the second Z-axis cylinder 174, the lower end of the driving block 175 is a cylinder, and the upper end is a cone. The first positioning assembly 176 includes a first connecting block 1761, an elastic telescopic member 1762, and a second connecting block 176 3. Positioning plate 1764, roller connecting rod 1765 and driving roller 1766. The first connecting block 1761 is fixed to the lower edge of the positioning platform 173. The elastic telescopic member 1762 is fixed on the first connecting block 1761 and the elastic end faces the driving block 175. The inner end of the second connecting block 1763 is fixed to the elastic end of the elastic telescopic member 1762. The positioning block is fixed to the outer end of the second connecting block 1763 and corresponds to the top of the positioning platform 173. The outer end of the roller connecting rod 1765 is fixed to the elastic end of the elastic telescopic member 1762. The driving roller 1766 is rotatably installed on the inner end of the roller connecting rod 1765 and abuts against the upper end of the driving block 175. The first positioning assembly 176 is arranged in four groups and corresponds to the four sides of the positioning platform 173.

[0052] In the initial state of the positioning platform 173, the second Z-axis cylinder 174 is in an upwardly extended state, and the driving block 175 causes the driving roller 1766 to run outward through the conical part, and finally the driving roller 1766 abuts against the cylindrical part of the driving block 175, and the elastic telescopic member 1762 is compressed, thereby driving the positioning plate 1764 to move outward. When the loading robot 14 grabs the pole piece and moves it above the positioning platform 173, the first Z-axis driving assembly 141 drives the suction cup assembly 147 to descend, so that the pole piece approaches the positioning platform 173. At this time, the second Z-axis cylinder 174 causes the driving block 175 to descend, and the driving roller 1766 abuts against the conical part of the driving block 175, thereby causing the four groups of positioning plates 1764 to move toward the middle, limiting the placement area of ​​the pole piece, and then, the loading robot 14 can release the pole piece, so that it falls into the area enclosed by the four groups of positioning plates 1764, so that the handling robot 15 can take the pole piece away.

The first X-axis slide 2442, the X-axis cylinder 2443, the first movable stand 2444, the third Z-axis cylinder 2445 and the metal pressure plate 2446 are arranged in a group on the front and back sides of the second mounting seat 2441 respectively. The two groups of metal pressure plates 2446 correspond to the front and back sides of the stacking platform 243 respectively. Two groups of film pressing assemblies 244 are arranged and correspond to the left and right sides of the stacking platform 243 respectively.

[0055] The first Y-axis driving assembly 22 drives the laminating platform 24 to reciprocate back and forth, and the diaphragm is unloaded from the diaphragm conveying assembly 25. The end of the diaphragm is laid flat on the laminating platform 243, and the four corners of the diaphragm are pressed tightly by four groups of metal pressing plates 2446. When the laminating platform 243 runs to the front side of the first Y-axis driving assembly 22, the third Z-axis cylinder 2445 on the rear side drives the metal pressing plate 2446 to lift and withdraw to the outside under the drive of the X-axis cylinder 2443. Then, the electrode loading station on the front side places a piece of electrode on top of the diaphragm, and then the metal pressing plate 2446 on the rear side resets inward and presses the electrode downward. The laminating platform 243 runs to the rear side of the first Y-axis driving assembly 22. During the backward movement of the laminating platform 243, the diaphragm Under the pull of the stacking platform 243, the membrane automatically folds forward and covers a layer of diaphragm on the electrode.

[0057] Before lamination begins, the end of the diaphragm is laid flat on the lamination carrier 243, and four groups of metal pressure plates 2446 press the diaphragm tightly. Then, the position of the diaphragm can be adjusted by the correction component 245. During adjustment, the metal pressure plate 2446 on the front side is released first, and then the adsorption holes on the rear side of the correction carrier 2453 adsorb the diaphragm, and the position of the diaphragm is sensed by the sensor on the equipment. Based on the position information, the correction motor 2451 drives the correction carrier 2453 to move on the second X-axis slide 2452 to bring the diaphragm to the desired position. Then, the adsorption holes on the front side of the lamination carrier 243 also adsorb the diaphragm to fix the diaphragm firmly. Then, the metal pressure plate 2446 on the front side presses the diaphragm again to complete the diaphragm correction process.

[0058] The diaphragm conveying assembly 25 is provided with a discharge roller assembly corresponding to the top of the first Y-axis driving assembly 22, and the discharge roller assembly includes a roller mounting frame 251, a discharge roller 252 and a guide rod 253.

[0061] When the stack reaches the specified thickness, the first Y-axis drive component 22 drives the stack carrier 243 to the rear side, and the cutting wire 266 corresponds to between the guide rod 253 and the metal pressure plate 2446 on the rear side. Then, the second lifting drive component 262 drives the second movable stand 263 to descend, so that the cutting wire 266 approaches the diaphragm, and then drives the third movable stand 265 to descend through the fourth Z-axis cylinder 264, so that the cutting wire 266 in a high temperature state contacts the diaphragm and cuts the diaphragm.

The track plate 3661 is fixed on the second mounting frame 364 and corresponds to the bottom of the adhesive tape unwinding assembly 365.

[0065] The second X-axis driving assembly 32 drives the movable base 33 to move left and right so that the clamping assembly 35 can load and unload materials from the right end. When the semi-finished product after lamination moves between the first clamping plate 354 and the second clamping plate 355, the first clamping driving assembly 352 and the second clamping driving assembly 353 respectively drive the first clamping plate 354 and the second clamping plate 355 to clamp the semi-finished product. Then, under the drive of the second X-axis driving assembly 32, the semi-finished product moves to the gluing assembly 36, and the adhesive paper unwinding assembly 365 conveys the adhesive paper to the upper end surface of the glue outlet track plate 3661. At this time, the sticky side of the adhesive paper faces upward, and the adhesive absorption through hole absorbs the adhesive paper so that the adhesive paper is evenly laid on the upper end surface of the glue outlet track plate 3661, but its adsorption force does not affect the lateral pulling action of the adhesive paper. The glue outlet limiting plate 3662 can limit the position of the adhesive paper. Then, the third Z-axis driving assembly Under the joint action of 362 and the second Y-axis driving assembly 363, the end of the glue discharge track plate 3661 is below the edge of the semi-finished product, and then the glue discharge track plate 3661 rises, so that the adhesive tape is attached to the lower end surface of the semi-finished product, and the glue discharge track plate 3661 withdraws to the outside of the semi-finished product. After the end of the glue discharge track plate 3661 is flush with the side of the semi-finished product, the glue discharge track plate 3661 rises, and the adhesive tape is attached to the side of the semi-finished product. Then, the glue discharge track plate 3661 moves toward the inner side of the upper end surface of the semi-finished product, so that the adhesive tape is attached to the upper end surface of the semi-finished product.

A V-groove 3751 is provided on one side of the translational positioning block 375, and one group of triangular bosses 3721 corresponds to the inside of the V-groove 3751.

[0069] When the rotation drive assembly 34 drives the first mounting frame 351 to rotate through the connecting shaft 371, the positioning cylinder 374 first drives the translation positioning block 375 to retract, so that the V-groove 3751 is disengaged from the triangular boss 3721, and then the rotation drive assembly 34 drives the connecting shaft 371 to rotate, so that the triangular boss 3721 on the next set of rotation positioning blocks 372 corresponds to the V-groove 3751, and then the positioning cylinder 374 drives the translation positioning block 375 to extend and be mounted outside the triangular boss 3721, thereby fixing the connecting shaft 371 to prevent the first mounting frame 351 from rotating during the glue application process.
