Description

Technical Field

[0001] This invention relates to the field of battery production equipment technology, and in particular to an arc-shaped battery feeding and winding mechanism. Background Technology

[0002] Curved lithium batteries, also known as curved batteries, are a type of irregularly shaped battery. By developing flexible current collectors and gradient structure electrode materials, the plasticity of the cell structure is achieved, thus enabling natural bending from 0° to 120°.

[0003] This design breaks free from the rigid constraints of traditional battery form factors, making it particularly suitable for applications such as smart wearable devices, flexible electronics, and medical implants that demand extreme thinness and flexibility.

[0004] For the production of curved batteries, the existing cell production methods on the market are mostly manual winding and stacking processes. It is difficult to form a regular curved cell during the manual winding process. At the same time, the tension control of the electrode is unstable during the winding process, which can easily lead to problems such as loose electrode winding, affecting the consistency and reliability of the curved battery. In addition, the cost is high and the production efficiency is low. Due to the cell structure design, problems such as uneven thickness and electrode alignment deviation are easily generated during the manufacturing process, which affects the consistency of the cell and the yield.

[0017] Compared with the prior art, the arc-shaped battery feeding and winding mechanism provided by the present invention has the following beneficial effects: This invention achieves automated and precise feeding, alignment, winding, and pressing of positive and negative electrode sheets through the coordinated action of the internal components of the feeding assembly and the positive and negative electrode sheet winding assembly.

[0026] The X-axis motor 212 drives the X-axis lead screw 216 to rotate, which in turn drives the X-axis drive seat to move, thereby causing the X-axis support plate 215 to slide along the X-axis guide rail 211, thus realizing the movement of the Z-axis moving assembly 22 in the X-axis direction.

[0027] Please see Figure 2 , Figure 4 and Figure 5 The Z-axis feeding assembly 22 includes a feeding L-shaped connecting plate 221 mounted on the upper end of the feeding X-axis support plate.

[0028] The Z-axis motor 226 drives the first Z-axis pulley 2210 to rotate, which in turn drives the second Z-axis pulley 2211 to rotate via belt 2212. This, in turn, drives the Z-axis lead screw 228 to rotate. The Z-axis lead screw 228 drives the Z-axis drive seat 229 to move, which in turn drives the Z-axis moving seat 224 to slide along the Z-axis guide rail 222, thus realizing the movement of the electrode material trough assembly 23 and the electrode clamping thermal composite assembly 24 in the Z-axis direction.

[0029] Please see Figure 2 , Figure 4 , Figure 6 and Figure 7The electrode material trough assembly 23 includes two alignment guide rails 231 spaced apart on the upper end of the feeding Z-axis moving seat 224, and two alignment rotating seats 232 perpendicular to the two alignment guide rails 231.

A positive electrode groove 2313 is opened at one end of the positive electrode feeding plate 2312. An adjusting positioning block 2314 is also provided at the upper end of the positive electrode feeding plate 2312. One end of the adjusting positioning block 2314 is in clearance fit with the positive electrode groove 2313. The adjusting positioning block 2314 is connected to the positive electrode feeding plate by bolts. The limiting position can be adjusted along the length of the positive electrode groove 2313 for the placement and positioning of the positive electrode sheet 4. The length of the positive electrode sheet 4 to be wound can be determined according to the needs. Several adsorption holes 2315 are opened linearly and equidistantly on the positive electrode groove 2313. An air pipe 2316 communicating with the adsorption holes 2315 is provided at the other end of the positive electrode feeding plate 2312. The upper end of the Z-axis moving seat 224 is provided with an alignment fixing seat 2317 located on the adjacent side of the two alignment guide rails 231.

One end of the negative electrode feeding plate 2318 is provided with a negative electrode groove 2319. Several adsorption holes 2320 are provided in a straight line at equal intervals on the negative electrode groove 2319. The upper end of the negative electrode feeding plate 2318 is provided with an air pipe 2321 that connects to the adsorption holes 2320. The positive electrode groove 2313 and the negative electrode feeding plate 2318 are used to limit the Y-axis direction of the positive electrode 4 and the negative electrode 5, respectively, and play a role in positioning in the Y-axis direction.

[0030] A receiving cylinder 2322 is also provided on one side of the positioning and fixing seat 2317. The telescopic end of the receiving cylinder 2322 is fixedly connected to a double L-shaped receiving plate 2323.

The bottom end of the double L-shaped receiving plate 2323 is provided with an air pipe 3 that connects to the adsorption holes 2324.

[0031] When the electrode material tank assembly 23 is working, the positive electrode 4 is placed in the positive electrode tank 2313 and connected to the negative pressure device through the air pipe 2316. The adsorption hole 2315 generates an adsorption force to fix the positive electrode 4 in the positive electrode tank 2313. The positioning block 2314 can limit the position of the positive electrode 4. The negative electrode 5 is placed in the negative electrode groove 2319 and connected to the negative pressure device through the second air pipe 2321. The second adsorption hole 2320 generates adsorption force to fix the negative electrode 5 in the negative electrode groove 2319. The alignment motor 238 drives the first alignment pulley 239 to rotate, which in turn drives the second alignment pulley 2310 to rotate via the second belt 2311. This, in turn, drives the alignment screw 235 to rotate. The alignment screw 235 drives the alignment drive seat 236 to move. The alignment drive seat 236 drives the alignment moving plate 234 to slide along the alignment guide rail 231, which in turn drives the positive electrode feeding plate 2312 to move. This moves the positive electrode slot 2313 to be directly above the negative electrode slot 2319, achieving precise alignment of the positive and negative electrode sheets. At the same time, the positive electrode slot 2313 and the negative electrode slot 2319 can prevent the positive and negative electrode sheets from shifting, effectively improving the winding quality of the electrode sheets. It should be further explained that the positive electrode mentioned above is an electrode covered with a diaphragm, which facilitates the isolation and winding with the negative electrode, while also increasing the frictional contact between the positive and negative electrodes and reducing the offset between them.

[0032] Please see Figure 2 and Figure 8 The electrode clamping thermal bonding assembly 24 includes a clamping support plate 241 disposed on the upper end of the L-shaped connecting plate 221 for feeding electrodes. Two conveying guide rails 242 are spaced apart on the upper end of the clamping support plate 241.

The output shaft of the conveying cylinder 244 is fixedly connected to one side of the conveying plate 246. A thermal bonding slide cylinder 247 is disposed on the upper end of the conveying plate 246. A thermal bonding clamping cylinder 248 is fixedly connected to the telescopic end of the thermal bonding slide cylinder 247. The upper and lower ends of the cylinder 248 are respectively equipped with a positive electrode clamping plate 249 and a negative electrode clamping plate 2410.

One side of the positive electrode clamping plate 249 and the negative electrode clamping plate 2410 is provided with a wire 2411 that is electrically connected to the upper heating composite plate 2491 and the lower heating composite plate 24101, which is used to drive the heating of the upper heating composite plate 2491 and the lower heating composite plate 24101, so that the clamped positive and negative electrode sheets are bonded together.

[0033] When the electrode clamping thermal bonding assembly 24 is working, the conveying cylinder 244 drives the conveying plate 246, the sliding table cylinder 247, and the thermal bonding clamping cylinder 248 to slide along the conveying guide rail 242. The thermal bonding sliding table cylinder 247 adjusts the position of the thermal bonding clamping cylinder 248 (the thermal bonding sliding table cylinder adjusts the position of the thermal bonding clamping cylinder in the horizontal direction (perpendicular to the conveying guide rail)) so that the grippers of the thermal bonding clamping cylinder 248 are aligned with the positive electrode sheet 4 and the negative electrode sheet 5 exposed on the positive electrode feeding plate 2312 and the negative electrode feeding plate 2318. Then, the conveying cylinder 244 drives the conveying plate 246, the sliding table cylinder 247, and the thermal bonding clamping cylinder 248 to slide along the conveying guide rail 242. 47 and the thermal bonding clamping cylinder 248 are reset, so that the positive and negative electrode sheets exposed in the positive electrode slot 2313 and negative electrode slot 2319 are located between the upper thermal bonding plate 2491 and the lower thermal bonding plate 24101. The thermal bonding clamping cylinder 248 drives the upper thermal bonding plate 2491 and the lower thermal bonding plate 24101 to clamp the positive and negative electrode sheets. At the same time, the upper thermal bonding plate 2491 and the lower thermal bonding plate 24101 are heated by electricity through the wire 2411, so that the positive and negative electrode sheets are thermally bonded together, providing a foundation for the subsequent winding of the positive and negative electrode sheets. This can effectively prevent the positive and negative electrode sheets from shifting during the winding process, which would affect the winding quality.

[0034] Subsequently, the receiving cylinder 2322 drives the double L-shaped receiving plate 2323 to move to the output port side of the negative electrode groove 2319. It is connected to the negative pressure device through the air pipe three. The adsorption hole three 2324 generates adsorption force to provide auxiliary support for the positive and negative electrode sheets after thermal bonding, and moves the positive and negative electrode sheets away from the output ports of the positive electrode groove 2313 and the negative electrode groove 2319 by one end, so as to facilitate subsequent conveying to the winding drive.

[0035] Next, the X-axis motor 212 drives the X-axis support plate 215 to slide along the X-axis guide rail 211, thereby transporting the thermally bonded positive and negative electrode sheets to the winding area of ​​the positive and negative electrode sheet winding assembly 3, completing the conveying process.

The installation adjustment plate 62 can adjust the horizontal position of the winding CCD image 63 and the orientation angle of the image head of the winding CCD image 63, which facilitates the adjustment of the winding position of the image head of the winding CCD image 63 corresponding to the winding needle; the configuration of the installation adjustment block 1 64, the adjustment vertical rod 65, the installation adjustment block 2 66 and the adjustment horizontal rod 67 facilitates the vertical and horizontal position adjustment of the supplementary lamp device 68, that is, the adjustment of the light orientation angle of the supplementary lamp device 68, so that its light is directed toward the orientation position of the image head of the winding CCD image 63; Both the winding CCD image 63 and the supplementary lighting device 68 are electrically connected to the control system of the device of this application. During the winding process of the positive and negative electrodes, the winding CCD image 63 can monitor the winding quality of the positive and negative electrodes in real time to ensure that the wound positive and negative electrodes are tight and qualified. At the same time, it can also prevent malfunctions in the winding process of the positive and negative electrodes and stop the winding of the positive and negative electrodes in time through the control console to avoid damage to other components. The supplementary lighting device 68 can provide supplementary lighting for the winding CCD image 63 to ensure that the device can still work in dim environments.

[0044] It also includes two support rods 69 located at the top of the support bracket 11 above the Z-axis moving assembly 22 of the film delivery, and image adjustment plates 70 are respectively provided on the side of the two support rods 69. Two film delivery CCD images 71 can be adjusted along the X-axis on the side of the two image adjustment plates 70, for a total of four film delivery CCD images 71. The images of the four film delivery CCD images 71 are all facing the positive and negative film delivery plates. The CCD image 71 can be adjusted along the X-axis on the image adjustment plate 70 according to the position of the positive and negative electrodes.

[0045] After the adjusting positioning block 2314 adjusts the appropriate length of the positive electrode 4 to be placed in the positive electrode slot 2313 according to the winding length of the positive electrode 4, the positive electrode 4 is placed into the positive electrode slot 2313 by an external device. Its end abuts against one side of the adjusting positioning block 2314 to form a positioning along the Y-axis. Then, the position information of the positive electrode 4 is taken by the feeding CCD image 71 and the information is transmitted to the control console. The control console controls the external gripper device (not shown in the figure) to place the negative electrode 5 in the negative electrode slot 2319. Its end corresponds to the end of the positive electrode 4 in the positive electrode slot 2313, thus forming the placement and positioning of the positive and negative electrodes.

[0046] The working principle of the present invention is as follows: When in use, the positive electrode 4 is first placed in the positive electrode groove 2313 of the electrode material groove assembly 23, and its end abuts against the over-adjustment positioning block 2314. The negative pressure device is connected through the air pipe 2316, and the adsorption hole 2315 generates adsorption force to fix the positive electrode 4, thus forming the initial positioning of the positive electrode 4. The placement position of the positive electrode 4 along the X-axis is detected by the CCD image 71. The negative electrode 5 is gripped by an external clamping device controlled by the control console and placed in the negative electrode slot 2319, aligned with the positive electrode along the X-axis. The negative pressure device is connected through the second air pipe 2321, and the second adsorption hole 2320 generates adsorption force to fix the negative electrode 5, forming the initial positioning of the negative electrode 5, which facilitates the subsequent thermal bonding alignment and winding of the positive and negative electrodes. Subsequently, the alignment motor 238 drives the positive electrode feeding plate 2312 to move, so that the positive electrode slot 2313 moves to directly above the negative electrode slot 2319, and the positive electrode slot 2313 is aligned with the negative electrode slot 2319, realizing the precise alignment of the positive and negative electrodes. Subsequently, the conveying cylinder 244 and the thermal bonding slide cylinder 247 of the electrode clamping thermal bonding assembly 24 operate, moving the thermal bonding clamping structure to the electrode material tray assembly 23. That is, the operation of the conveying cylinder 244 drives the conveying plate 246, the slide cylinder 247, and the thermal bonding clamping cylinder 248 to slide along the conveying guide rail 242, and the operation of the thermal bonding slide cylinder 247 adjusts the position of the thermal bonding clamping cylinder 248 so that the grippers of the thermal bonding clamping cylinder 248 are aligned with the positive electrode 4 and negative electrode 5 exposed on the positive electrode feeding plate 2312 and the negative electrode feeding plate 2318. Subsequently, the conveying cylinder 244 operates to reset the conveying plate 246, the sliding table cylinder 247, and the thermal bonding clamping cylinder 248, so that the positive and negative electrode sheets with the positive electrode slots 2313 and 2319 exposed are located between the upper thermal bonding plate 2491 and the lower thermal bonding plate 24101. The thermal bonding clamping cylinder 248 drives the upper thermal bonding plate 2491 and the lower thermal bonding plate 24101 to clamp the positive and negative electrode sheets. At the same time, the upper thermal bonding plate 2491 and the lower thermal bonding plate 24101 are heated by electricity through the wire 2411, so that the positive and negative electrode sheets are thermally bonded together. Next, the receiving cylinder 2322 drives the double L-shaped receiving plate 2323 to move to the output port side of the negative electrode groove 2319. It is connected to the negative pressure device through the air pipe three. The adsorption hole three 2324 generates adsorption force to provide auxiliary support for the positive and negative electrode sheets after thermal bonding. It moves the positive and negative electrode sheets away from the output ports of the positive electrode groove 2313 and the negative electrode groove 2319 by one end, so that the positive and negative electrode sheets after subsequent thermal bonding can be transported to the winding area. Next, the X-axis feeding assembly 21 and the Z-axis feeding assembly 22 operate, driving the thermally bonded positive and negative electrode sheets to move back and forth. In conjunction with the Z-axis feeding motor 226, the first Z-axis pulley 2210 rotates, which in turn drives the second Z-axis pulley 2211 to rotate via belt 2212. This, in turn, drives the Z-axis feeding screw 228 to rotate, which in turn drives the Z-axis feeding drive seat 229 to move up and down. This, in turn, drives the thermally bonded positive and negative electrode sheets on the electrode material tray assembly 23 to move up and down. The thermally bonded positive and negative electrode sheets are then transported to the positive and negative electrode sheet winding assembly 3 until they are positioned between the winding needles A328 and B329, facilitating their clamping by the winding needles A328 and B329. Next, the main winding Y-axis moving assembly 33 and the winding needle nozzle Y-axis moving assembly 35 work, driving the main winding assembly 32 and the winding needle assembly 34 to move, so that the winding needles A328 and B329 align with the positive and negative electrode plates. Then, the main winding clamping cylinder 327 drives the winding needles A328 and B329 to clamp the positive and negative electrode plates, that is, to fix the starting ends of the positive and negative electrode plates in the slots 3211 between the winding needles A328 and B329. The main winding Y-axis moving assembly 33 and the winding needle nozzle Y-axis moving assembly 35 continue to work, driving the main winding assembly 32 and the winding needle assembly 34 to move, so that the grooves 34111 on the winding needle rotating block 3411 align with the protrusions 3210 of the winding needle. The winding motor 348 and the main winding motor 323 drive the winding needles A328 and B329 and the positive and negative electrode sheets to rotate. At the same time, the feeding pressure roller assembly 363 works to drive the feeding pressure roller 3638 to abut against the wound positive and negative electrode sheets. The upper pressure roller assembly 361 and the lower pressure roller assembly 362 work, and the upper pressure roller 36115 and the lower pressure roller 36216 press the upper and lower ends of the wound electrode sheets to make the positive and negative electrode sheets more tightly wound. Until the winding of the positive and negative electrode sheets is completed, the electrode sheets wound on the winding needles A and B are taken out by the external material taking equipment, completing the feeding, winding and taking out process of the arc battery.
