Description

Technical Field

[0001] This invention relates to the field of lithium battery stacking equipment, and particularly to an electrode stacking equipment. Background Technology

[0002] Winding and stacking are the core processes in the mid-stage cell assembly of lithium-ion batteries, representing two distinct cell manufacturing techniques. Winding involves rolling slits of electrodes, separators, and termination tapes of matching dimensions into a core. Stacking, on the other hand, involves alternately stacking electrodes and separators to create a multi-layered stacked core. For Z-shaped stacked lithium-ion batteries, the separators are arranged in a continuous Z-shape, with electrodes placed between each layer of separator.

[0003] In traditional electrode stacking equipment, the stacking platform is fixed, and the diaphragm conveying mechanism repeatedly lays the diaphragm on the stacking platform. When the diaphragm is about to be reversed, a robotic arm picks up the electrode and places it on the diaphragm. However, the diaphragm is laid quickly, but the efficiency of the robotic arm in picking up the electrode from the previous process cannot keep up, thus affecting the overall stacking efficiency. Therefore, it is necessary to develop an electrode stacking equipment to solve the above problems. Summary of the Invention

[0015] Further description of the invention: The adhesive applicator also includes a second positioning component, which includes a connecting shaft, a rotary positioning block, a Y-axis slide, a positioning cylinder, and a translational positioning block.

A V-groove is provided on one side of the translational positioning block, and one set of triangular bosses corresponds to the V-groove.

[0016] The beneficial effects of this invention are as follows: The first Y-axis drive assembly drives the stacking platform to reciprocate back and forth. The diaphragm is unloaded from the diaphragm conveying assembly, and the end of the diaphragm is laid flat on the stacking platform. The four corners of the diaphragm are pressed together by four sets of metal pressure plates. When the stacking platform moves to the front of the first Y-axis drive assembly, the third Z-axis cylinder on the rear side drives the metal pressure plate to lift and then retracts outward under the drive of the X-axis cylinder. Then, the electrode loading station on the front side places an electrode on top of the diaphragm. Then, the metal pressure plate on the rear side resets inward and presses the electrode downward. When the stacking platform moves to the rear of the first Y-axis drive assembly, during the backward movement of the stacking platform, the diaphragm... Under the tension of the lamination stage, the membrane automatically folds forward and covers the electrode with a diaphragm. Then, the third Z-axis cylinder on the front side drives the metal pressure plate to rise and, driven by the X-axis cylinder, retracts outward. Next, the electrode loading station on the rear side places an electrode on top of the diaphragm. Then, the metal pressure plate on the front side returns to its original position and presses the electrode downward. The lamination stage moves to the front of the first Y-axis drive assembly. This operation is repeated, so that the diaphragm is laid in a Z-shape on the lamination stage, and the electrode is placed between the diaphragms. As the thickness of the laminate gradually increases, the first lifting drive assembly drives the lamination stage to gradually descend to adapt to the loading position of the electrode loading station. The advantage of this design is that it can drive the lamination stage to move back and forth, allowing two sets of electrode loading stations to be set up on the front and rear sides respectively. The two sets of electrode loading stations alternate loading, thereby improving the efficiency of lamination. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings:

[0038] like Figure 1 As shown, an electrode stacking device includes a feeding mechanism 1, a stacking mechanism 2, an adhesive application mechanism 3, and a transfer mechanism 4. The stacking mechanism 2 is fixedly located downstream of the feeding mechanism 1, and the transfer mechanism 4 is fixedly located between the stacking mechanism 2 and the adhesive application mechanism 3.

[0039] The feeding mechanism 1 transports the electrode sheet to the stacking mechanism 2, where it is stacked in a Z-shape with the diaphragm on the stacking mechanism 2. The stacked semi-finished product is then transported to the adhesive applicator 3 via the transfer mechanism 4. The adhesive applicator 3 applies adhesive to all four sides of the semi-finished product before transferring it to the transfer mechanism 4 for unloading.

[0040] like Figures 2 to 6 As shown, the feeding mechanism 1 includes a first mounting platform 11, a mounting frame 12, a first X-axis drive assembly 13, a feeding robot 14, a handling robot 15, a feeding platform 16, and a positioning platform 17. The mounting frame 12 is vertically fixed above the first mounting platform 11. The first X-axis drive assembly 13 is fixed at the upper end of the mounting frame 12. The feeding robot 14 and the handling robot 15 are respectively fixed at the power output ends on the left and right sides of the first X-axis drive assembly 13. The feeding platform 16 and the positioning platform 17 are both fixed on the first mounting platform 11 and are respectively below the feeding robot 14 and the handling robot 15.

[0041] The loading robot 14 includes a first Z-axis drive assembly 141, a lifting plate 142, a fixed horizontal plate 143, a bending plate 144, a bending cylinder 145, a suction cup mounting bracket 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 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 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 upper part of the fixed horizontal plate 143 and is hinged to the lifting plate 142. The front end of the bending cylinder 145 is the power output end and is hinged to the bending plate 144. Two sets of suction cup mounting brackets 146 are provided and fixed to the fixed horizontal plate 143 and the bending plate 144 respectively. The suction cup assembly 147 is fixed to the left and right ends of the suction cup mounting bracket 146.

[0042] The neatly stacked electrode sheets are placed on the loading platform 16. The loading robot 14 picks them up one by one and moves them to the positioning platform 17 for positioning. The transport robot 15 transports the electrode sheets on the positioning platform 17 to the next process. When the loading robot 14 picks up the electrode sheets, 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 can adsorb the topmost electrode sheet. Then, the lifting plate 142 rises, and the bending cylinder 145 drives the bending plate 144 to bend downward at a certain angle, thereby bending the electrode sheet. If there are other electrode sheets attached to the bottom of the topmost electrode sheet, they will fall off as the electrode sheet bends, thus ensuring that the loading robot 14 transports only one electrode sheet at a time. After the bending plate 144 is folded and reset, the loading robot 14 can then transport the electrode sheet to the positioning platform 17. The advantage of this design is that it can prevent the electrode sheets from overlapping during the material handling process, ensuring that only one electrode sheet is transported at a time, thereby ensuring the stability of subsequent processing.

[0043] The first X-axis drive assembly 13, the loading robot 14, the handling robot 15, the loading platform 16, and the positioning platform 17 are arranged symmetrically in two sets about the front and rear of the mounting frame 12. This allows for the simultaneous transport of two sets of electrode sheets, facilitating efficient subsequent stacking processes.

[0044] The first Z-axis drive assembly 141 includes a fixed plate 1411, a Z-axis slide 1412, a first Z-axis cylinder 1413, and a Z-axis slider 1414. The fixed plate 1411 is fixed to the power output end of the first X-axis drive assembly 13. The Z-axis slide 1412 and the first Z-axis cylinder 1413 are both fixed on the fixed plate 1411. The lifting 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 plate 142 and is slidably connected to the Z-axis slide 1412.

[0045] The first Z-axis drive assembly 141 drives the lifting plate 142 to slide vertically on the Z-axis slide table 1412.

[0046] The feeding platform 16 includes a material frame 161, a second Z-axis drive assembly 162, a feeding platform 163, and electrode brushes 164. The material frame 161 is fixed above the first mounting platform 11 and corresponds to the lower part of the feeding robot 14. The material frame 161 is provided with a feeding cavity 1611. The second Z-axis drive assembly 162 is fixed on the first mounting platform 11. The feeding platform 163 is fixed at the power output end of the second Z-axis drive assembly 162 and corresponds to the feeding cavity 1611. The electrode brushes 164 are fixedly arranged and correspond to the upper part of the feeding platform 163. Multiple sets of electrode brushes 164 are arranged and correspond to the front and rear sides of the feeding platform 163. The brush ends of the electrode brushes 164 correspond to the edge of the feeding cavity 1611.

[0047] The neatly stacked electrode sheets are placed in the feeding cavity 1611. As the electrode sheets are continuously removed, the second Z-axis drive assembly 162 gradually raises the feeding platform 163 to facilitate the picking action of the feeding robot 14. When the feeding robot 14 picks up the electrode sheet and rises, the edge of the electrode sheet contacts the electrode brush 164. If there are other electrode sheets attached to the bottom of the top electrode sheet, they will be scraped off by the electrode brush 164, further ensuring that the feeding robot 14 picks up only one electrode sheet.

[0048] 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 drive 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 its power output end facing upwards, and the drive block 175 is fixed to the power output end of the second Z-axis cylinder 174. The lower end of the drive block 175 is cylindrical, and the upper end is conical. The first positioning assembly 176 includes a first connecting block 1761, an elastic telescopic member 1762, and a second connecting block 1763. The system includes a positioning plate 1764, a roller connecting rod 1765, and a drive roller 1766. A first connecting block 1761 is fixed to the lower edge of the positioning platform 173. An elastic telescopic member 1762 is fixed to the first connecting block 1761 with its elastic end facing the drive 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 plate 1764 is fixed to the outer end of the second connecting block 1763 and corresponds to the upper part 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 drive roller 1766 is rotatably mounted on the inner end of the roller connecting rod 1765 and abuts against the upper end of the drive block 175. Four sets of the first positioning components 176 are provided and correspond to the four sides of the positioning platform 173.

[0049] In the initial state of the positioning platform 173, the second Z-axis cylinder 174 is extended upwards. The drive block 175 causes the drive roller 1766 to move outwards through the conical part. Finally, the drive roller 1766 abuts against the cylindrical part of the drive block 175, and the elastic telescopic member 1762 is compressed, thereby driving the positioning plate 1764 to move outwards. When the loading robot 14 grabs the electrode and moves it above the positioning platform 173, the first Z-axis drive assembly 141 drives the suction cup assembly 147 to descend, bringing the electrode close to the positioning platform 173. At this time, the second Z-axis cylinder 174 causes the drive block 175 to descend, and the drive roller 1766 abuts against the conical part of the drive block 175, thereby moving the four sets of positioning plates 1764 towards the center to limit the placement area of ​​the electrode. Subsequently, the loading robot 14 can release the electrode, allowing it to fall into the area enclosed by the four sets of positioning plates 1764, so that the handling robot 15 can remove the electrode.

[0050] like Figures 7 to 10 As shown, the stacking mechanism 2 includes a second mounting platform 21, a first Y-axis drive assembly 22, a movable base plate 23, a stacking platform 24, and a diaphragm conveying assembly 25. The first Y-axis drive assembly 22 is fixed above the second mounting platform 21, the movable base plate 23 is fixed to the power output end of the first Y-axis drive assembly 22, the stacking platform 24 is fixed above the movable base plate 23, and the diaphragm conveying assembly 25 is mounted on the upper middle part of the first Y-axis drive assembly 22.

[0051] The stacking platform 24 includes a first mounting base 241, a first lifting drive assembly 242, a stacking stage 243, and a pressing assembly 244. The first mounting base 241 is fixed above the movable base plate 23. The first lifting drive assembly 242 is fixed on the first mounting base 241. The stacking stage 243 is fixed on the power output end of the first lifting drive assembly 242. The pressing assembly 244 includes a second mounting base 2441, a first X-axis slide 2442, an X-axis cylinder 2443, a first movable upright 2444, a third Z-axis cylinder 2445, and a metal pressing plate 2446.

A third Z-axis cylinder 2445 is fixed on the first movable support frame 2444. A metal pressure plate 2446 is fixed to the power output end of the third Z-axis cylinder 2445 and corresponds to the edge above the stacking stage 243. The first X-axis slide 2442, the X-axis cylinder 2443, the first movable support frame 2444, the third Z-axis cylinder 2445, and the metal pressure plate 2446 are each arranged in a set on the front and rear sides of the second mounting base 2441. The two sets of metal pressure plates 2446 correspond to the front and rear sides of the stacking stage 243, respectively. Two sets of pressing assembly 244 are arranged and correspond to the left and right sides of the stacking stage 243, respectively.

[0052] The first Y-axis drive assembly 22 drives the stacking platform 24 to reciprocate back and forth. The diaphragm is unloaded from the diaphragm conveying assembly 25, and its ends are laid flat on the stacking stage 243. Four sets of metal pressure plates 2446 press the four corners of the diaphragm together. When the stacking stage 243 moves to the front of the first Y-axis drive assembly 22, the rear third Z-axis cylinder 2445 drives the metal pressure plates 2446 to rise and then retracts outward under the drive of the X-axis cylinder 2443. Next, the front electrode loading station places an electrode on top of the diaphragm. Then, the rear metal pressure plates 2446 reset inward and press the electrode downward. The stacking stage 243 moves to the rear of the first Y-axis drive assembly 22. During the backward movement of the stacking stage 243, the diaphragm... Under the pull of the stacking stage 243, the membrane automatically folds forward and covers the electrode with a diaphragm. Then, the third Z-axis cylinder 2445 on the front side drives the metal pressure plate 2446 to rise and retracts outward under the drive of the X-axis cylinder 2443. Next, the electrode loading station on the rear side places an electrode on top of the diaphragm. Then, the metal pressure plate 2446 on the front side resets inward and presses the electrode downward. The stacking stage 243 moves to the front of the first Y-axis drive assembly 22. This operation is repeated so that the diaphragm is laid in a Z-shape on the stacking stage 243 and the electrode is placed between the diaphragms. As the thickness of the stack gradually increases, the first lifting drive assembly 242 drives the stacking stage 243 to gradually descend to adapt to the loading position of the electrode loading station. The advantage of this design is that it can drive the stacking stage 243 to move back and forth, so that two sets of electrode loading stations can be set on the front and back sides respectively. The two sets of electrode loading stations can load materials alternately, thereby improving the stacking efficiency.

[0053] The stacking platform 24 also includes a correction component 245, which includes a correction motor 2451, a second X-axis slide 2452, and a correction platform 2453. The correction motor 2451 and the second X-axis slide 2452 are fixed on the first mounting base 241. The correction platform 2453 is fixed to the power output end of the correction motor 2451 and is slidably connected to the second X-axis slide 2452. The upper end surface of the correction platform 2453 is flush with the upper end surface of the stacking platform 243. The rear side of the correction platform 2453 and the front side of the stacking platform 243 are provided with adsorption vents, which are connected to an air extraction device.

[0054] Before the lamination begins, the end of the diaphragm is laid flat on the lamination stage 243, and four sets of metal pressure plates 2446 press the diaphragm tightly. Then, the position of the diaphragm can be adjusted by the correction assembly 245. During adjustment, the front metal pressure plate 2446 is released first, and then the adsorption vent on the rear side of the correction stage 2453 adsorbs the diaphragm. 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 stage 2453 to move on the second X-axis slide 2452 to place the diaphragm in the required position. Then, the adsorption vent on the front side of the lamination stage 243 also adsorbs the diaphragm to fix the diaphragm position firmly. Then, the front metal pressure plate 2446 presses the diaphragm again, thus completing the diaphragm correction process.

[0055] The diaphragm conveying assembly 25 is provided with a discharge roller assembly corresponding to the first Y-axis drive assembly 22. The discharge roller assembly includes a roller mounting frame 251, a discharge roller 252 and a guide rod 253. The discharge roller 252 is rotatably mounted on the roller mounting frame 251.

The cutting wire 266 corresponds to the rear side of the guide rod 253 and is connected to the heating equipment.

[0058] When the stacked sheets reach the specified thickness, the first Y-axis drive assembly 22 drives the stacking platform 243 to the rear side, and the cutting wire 266 corresponds between the guide rod 253 and the rear metal pressure plate 2446. Then, the second lifting drive assembly 262 drives the second movable stand 263 to descend, so that the cutting wire 266 approaches the diaphragm. Then, the fourth Z-axis cylinder 264 drives the third movable stand 265 to descend, so that the cutting wire 266, which is in a high-temperature state, contacts the diaphragm and cuts the diaphragm.

[0059] The stacking platform 243 is provided with a material taking-out clearance groove 2431 on the rear side. The rear end of the material taking-out clearance groove 2431 is open.

The power output end of the rotary drive assembly 34, the first clamping drive assembly 352 and the second clamping drive assembly 353 are respectively fixed on the upper and lower sides of the first mounting frame 351, the first clamping plate 354 and the second clamping plate 355 are arranged facing each other and are respectively fixed on the power output ends of the first clamping drive assembly 352 and the second clamping drive assembly 353, the first clamping plate 354 is provided with a first adhesive clearance groove 3541 around its perimeter, the second clamping plate 355 is provided with a second adhesive clearance groove 3551 around its perimeter, the adhesive application assembly 36 includes a vertical bracket 361, a third Z-axis drive assembly 362, a second Y-axis drive assembly 363, and a second mounting frame 351. The system comprises a frame 364, an adhesive tape unwinding assembly 365, and an adhesive dispensing assembly 366. A vertical bracket 361 is fixed above the third mounting platform 31. A third Z-axis drive assembly 362 is fixed on the vertical bracket 361. A second Y-axis drive assembly 363 is fixed to the power output end of the third Z-axis drive assembly 362. A second mounting frame 364 is fixed to the power output end of the second Y-axis drive assembly 363. The adhesive tape unwinding assembly 365 is fixed to the upper side of the second mounting frame 364. The adhesive dispensing assembly 366 includes an adhesive dispensing track plate 3661, an adhesive dispensing limit plate 3662, a Y-axis cylinder 3663, and a cutter 3664. The guide plate 3661 is fixed on the second mounting frame 364 and corresponds to the lower part of the adhesive unwinding assembly 365. The middle part of the adhesive dispensing guide plate 3661 is horizontally provided with a knife placement groove 36611. The upper part of the adhesive dispensing guide plate 3661 is uniformly provided with adhesive suction holes, which are connected to the air extraction equipment.

[0062] The second X-axis drive assembly 32 drives the movable base 33 to move left and right, so that the clamping assembly 35 can load and unload from the right end. When the stacked semi-finished product moves between the first clamping plate 354 and the second clamping plate 355, the first clamping drive assembly 352 and the second clamping drive assembly 353 respectively drive the first clamping plate 354 and the second clamping plate 355 to clamp the semi-finished product. Then, driven by the second X-axis drive assembly 32, the semi-finished product moves to the adhesive application assembly 36. The adhesive unwinding assembly 365 conveys the adhesive paper to the upper surface of the adhesive dispensing track plate 3661. At this time, the sticky side of the adhesive paper faces upward, and the adhesive suction hole absorbs the adhesive paper, so that the adhesive paper is laid flat on the upper surface of the adhesive dispensing track plate 3661. However, its suction force does not affect the lateral pulling action of the adhesive paper. The adhesive dispensing limit plate 3662 can limit the position of the adhesive paper. Then, the third Z-axis drive assembly Under the combined action of 362 and the second Y-axis drive assembly 363, the end of the glue dispensing track plate 3661 is positioned below the edge of the semi-finished product. Then, the glue dispensing track plate 3661 rises, adhering the adhesive to the lower end face of the semi-finished product. The glue dispensing track plate 3661 retracts to the outside of the semi-finished product. After the end of the glue dispensing track plate 3661 is flush with the side of the semi-finished product, the glue dispensing track plate 3661 rises again, adhering the adhesive to the side of the semi-finished product. Next, the glue dispensing track plate 3661 moves to the inside of the upper end face of the semi-finished product, adhering the adhesive to the upper end face of the semi-finished product. At this time, the adhesive covers the opening of the knife slot 36611. The cutter 3664 is driven to extend by the Y-axis cylinder 3663, thereby cutting the adhesive. The adhesive application on one side of the semi-finished product is completed. Then, the first mounting frame 351 is driven to rotate by the rotation drive assembly 34, thereby performing the adhesive application process on all four sides of the semi-finished product. The advantage of this design is that adhesive can be applied to all four sides of the stacked lithium battery semi-finished product without flipping it, thereby improving the efficiency of adhesive application.

[0063] The first clamping plate 354 is provided with a first material placement and clearance groove 3542 on both the left and right sides, and the second clamping plate 355 is provided with a second material placement and clearance groove 3552 on both the left and right sides.

[0065] In this design, the adhesive applicator 3 also includes a second positioning component 37. The second positioning component 37 includes a connecting shaft 371, a rotary positioning block 372, a Y-axis slide 373, a positioning cylinder 374, and a translational positioning block 375. The upper end of the connecting shaft 371 is fixed to the lower end of the first mounting frame 351, and the lower end of the connecting shaft 371 is fixed to the power output end of the rotary drive component 34. Four sets of rotary positioning blocks 372 are provided and fixed around the connecting shaft 371 respectively. The rotary positioning block 372 is provided with outwardly protruding triangular bosses 3721. The Y-axis slide 373 and the positioning cylinder 374 are both fixed above the movable base 33.

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

[0066] When the rotary drive assembly 34 drives the first mounting frame 351 to rotate via the connecting shaft 371, the positioning cylinder 374 first drives the translation positioning block 375 to retract, causing the V-groove 3751 to disengage from the triangular boss 3721. Then, the rotary drive assembly 34 drives the connecting shaft 371 to rotate, so that the triangular boss 3721 on the next set of rotary positioning blocks 372 corresponds to the V-groove 3751. Next, the positioning cylinder 374 drives the translation positioning block 375 to extend and fit over the triangular boss 3721, thereby fixing the connecting shaft 371 and preventing the first mounting frame 351 from rotating during the adhesive application process.
