Description

Technical Field

[0001] This invention relates to the field of pouch battery manufacturing technology, and in particular to a pouch battery double-sealing and double-side forming dual-channel integrated machine. Background Technology

[0002] In the standardized manufacturing process of pouch batteries, after the cell is initially packaged, the aluminum-plastic film skirts on both sides will have different specifications, exhibiting a structural feature of one side having a long skirt and the other side having a short skirt. After initial packaging, the cell still needs to undergo a series of meticulous processing steps, including tab detection, long skirt puncture and venting, skirt heat sealing, and double-sided skirt bends and leveling. The alignment accuracy and processing quality of each step directly determine the finished product quality and production yield of the pouch battery. In existing production processes, core processing steps such as tab detection, venting, and heat sealing all rely on the short skirt as a positioning reference. This requires the short skirt to remain completely flat and smooth, without wrinkles, warping, or deformation defects. If wrinkles or deformation occur on the short skirt, it will directly cause cell positioning misalignment, leading to inaccurate tab detection, puncture position deviation, and misaligned heat sealing, among other process defects. This not only reduces processing accuracy and production efficiency but also easily leads to battery leakage, bulging, and sealing failure, seriously affecting the performance and lifespan of the pouch battery. Therefore, it is necessary to develop an integrated machine for double sealing and double-side forming of soft-pack batteries in a dual-channel configuration to solve the above problems.

[0015] The beneficial effects of this invention are as follows: Batteries are neatly arranged in the material frame and fed one by one to the support platform of the edge-straightening mechanism by the feeding mechanism. The short skirt on the battery corresponds between the upper and lower sets of clamping blocks. Then, the clamping cylinder drives the upper and lower sets of clamping blocks to move closer together, and the rollers on the upper and lower sides clamp the skirt. The edge-straightening pressing block is in contact with the skirt or has a slight gap. Before the edge-straightening action, the roller corresponds to the middle of the skirt. On the same side of the skirt, the two sets of edge-straightening pressing blocks correspond to the outer sides of the two sets of rollers. Then, the reciprocating drive assembly drives the two sets of edge-straightening components to move to the left and right ends of the skirt. On the moving path, the edge-straightening pressing block scrapes the skirt flat to prevent the skirt from overlapping or wrinkling. Then, the rollers further flatten the skirt, thereby completing the edge-straightening. Next, the battery undergoes voltage testing on the voltage testing mechanism. After the test is completed, the battery undergoes secondary packaging on the packaging sub-machine. Then, the transfer and transport mechanism transports the battery to the side forming mechanism for edge shaping. The advantage of this design is that it ensures the hem of the skirt remains smooth and flat, free from wrinkles, warping, and deformation. This improves the precision and finish of subsequent processing steps. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1 to 13As shown, a dual-channel integrated machine for double-sealing and dual-side forming of soft-pack batteries includes a feeding mechanism 1, an edge-straightening mechanism 2, a voltage testing mechanism 3, a packaging sub-machine 4, a side-forming mechanism 5, and a transfer and handling mechanism 6. The feeding mechanism 1, edge-straightening mechanism 2, and voltage testing mechanism 3 are arranged sequentially from right to left. Multiple packaging sub-machines 4 are arranged to the left of the voltage testing mechanism 3. The transfer and handling mechanism 6 is located between the packaging sub-machine 4 and the side-forming mechanism 5. The edge-straightening mechanism 2 includes a support platform 21, a mounting base 22, an adjusting seat 23, a reciprocating drive assembly 24, and an edge-straightening assembly 25. The support platform 21 is fixed between the feeding mechanism 1 and the voltage testing mechanism 3. The mounting base 22 is fixedly arranged on the front side of the support platform 21. The adjusting seat 23 is fixed above the mounting base 22 and its position is adjustable in the front-rear direction. The reciprocating drive assembly 24 is fixed above the adjusting seat 23. The edge-straightening assembly 25... 5. At least two sets of edge-straightening components are provided on the power output end of the reciprocating drive assembly 24 and driven by the reciprocating drive assembly 24 to move in opposite directions. The edge-straightening assembly 25 includes a mounting vertical plate 251, a clamping cylinder 252, a clamping block 253, a roller 254, and an edge-straightening pressure block 255. The mounting vertical plate 251 is fixed to the power output end of the reciprocating drive assembly 24. The clamping cylinder 252 is fixed on the mounting vertical plate 251 and corresponds to one side of the support platform 21. The clamping block... Two sets of rollers 253 are fixed on the upper and lower power output ends of the clamping cylinder 252. The rollers 254 are rotatably mounted on the rear side of the clamping block 253. The upper and lower sets of rollers 254 are arranged facing each other. The edge-straightening pressure block 255 is fixed on the clamping block 253 and corresponds to one side of the rollers 254. The upper and lower sets of edge-straightening pressure blocks 255 are arranged facing each other. Each pair of edge-straightening components 25 are symmetrically arranged. The edge-straightening pressure block 255 corresponds to the outer side of the rollers 254.

[0033] Batteries are neatly arranged in the material frame and fed one by one by the feeding mechanism 1 onto the support platform of the edge-straightening mechanism 2. The short skirt on the battery corresponds between the upper and lower clamping blocks 253. Then, the clamping cylinder 252 drives the upper and lower clamping blocks 253 to move closer together. The rollers 254 on the upper and lower sides clamp the skirt. The edge-straightening pressing block 255 is in contact with the skirt or has a slight gap. Before the edge-straightening action, the roller 254 corresponds to the middle of the skirt. On the same side of the skirt, the two sets of edge-straightening pressing blocks 255 correspond to the outer sides of the two sets of rollers 254. Then, the reciprocating drive assembly 24 drives the two sets of edge-straightening assemblies 25 to move to the left and right ends of the skirt. On the moving path, the edge-straightening pressing block 255 scrapes the skirt flat to prevent the skirt from overlapping or wrinkling. Then, the rollers 254 further flatten the skirt, thereby completing the edge-straightening. Next, the battery undergoes a voltage test on the voltage testing mechanism 3. After the test, the battery undergoes a secondary packaging on the packaging sub-machine 4. Then, the transfer and conveying mechanism 6 transports the battery to the side forming mechanism 5 for skirt shaping. The advantage of this design is that it can keep the short skirt flat and smooth overall, without wrinkles, warping, or deformation defects. This improves the accuracy and processing effect of subsequent processing steps.

[0034] The inner end faces of the upper and lower sets of edge-straightening blocks 255 are right-angled triangles, with the hypotenuse corresponding to the side away from the roller 254. When the edge-straightening blocks 255 move and smooth the short skirt, the hypotenuse on the triangular end face contacts the protruding part on the skirt first, reducing the moving resistance and smoothing the skirt more smoothly.

[0035] The reciprocating drive assembly 24 includes a rotary motor 241, a synchronous pulley 242, a synchronous belt 243, and a drive plate 244. The rotary motor 241 is fixed on the right side above the adjusting seat 23. Two sets of synchronous pulleys 242 are provided. The left synchronous pulley 242 is rotatably mounted on the left side above the adjusting seat 23, and the right synchronous pulley 242 is fixed to the power output end of the rotary motor 241. The synchronous belt 243 is wrapped around the outside of the two sets of synchronous pulleys 242 and meshes with the synchronous pulleys 242. The rear end of the drive plate 244 is fixed on the edge trimming assembly 25, and the front ends of two adjacent sets of drive plates 244 are respectively fixed to the front and rear sides of the synchronous belt 243.

[0036] The rotary motor 241 drives the synchronous belt 243 to rotate via the synchronous pulley 242. Since the adjacent drive plates 244 are fixed to the front and rear sides of the synchronous belt 243 respectively, when the synchronous belt 243 rotates, it will drive the two adjacent sets of edge-trimming assemblies 25 to move in the opposite direction.

[0037] The voltage testing mechanism 3 includes an X-axis drive assembly 31, a movable support 32, a Z-axis drive assembly 33, a material transfer device 34, a Y-axis drive assembly 35, a positioning platform 36, and a testing device 37. The movable support 32 is fixed to the power output end of the X-axis drive assembly 31, and the Z-axis drive assembly 33 is fixed to the movable support 32. The material transfer device 34 includes a first connecting plate 341, an adsorption plate 342, a horizontal adjustment plate 343, a vertical adjustment plate 344, and an electrode clamping plate 345. The rear end of the first connecting plate 341 is fixed... The power output end of the Z-axis drive assembly 33 is fixed. The upper end of the adsorption plate 342 is fixed to the front end of the first connecting plate 341 and its position is adjustable in the front-rear direction. Multiple suction cups are provided below the adsorption plate 342. The horizontal adjustment plate 343 is fixed to the front end of the first connecting plate 341 and its position is adjustable in the left-right direction. The upper end of the vertical adjustment plate 344 is fixed to the left end of the horizontal adjustment plate 343 and its position is adjustable in the vertical direction. The electrode pressure plate 345 is fixed to the lower end of the vertical adjustment plate 344 and corresponds to the left side of the adsorption plate 342. The X-axis drive assembly 35 is fixedly mounted on the front side of the X-axis drive assembly 31. The positioning platform 36 is fixed at the power output end of the Y-axis drive assembly 35 and corresponds to the lower part of the adsorption plate 342. The detection device 37 includes a second connecting plate 371, a first mounting base 372, a first Z-axis cylinder 373, a first lifting plate 374, an insulating block 375, and a detection pressure plate 376. The second connecting plate 371 is fixed on the left side of the positioning platform, the first mounting base 372 is fixed on the second connecting plate 371, and the first Z-axis cylinder 373 is fixed on the left side of the positioning platform. On the first mounting base 372, the first lifting plate 374 is fixed to the power output end of the first Z-axis cylinder 373, the insulating block 375 is fixed to the upper end of the first lifting plate 374, and the detection pressure plate 376 is fixed above the insulating block 375 and below the tab pressure plate 345. The detection pressure plate 376 is made of metal and is electrically connected to the detection equipment. The first Z-axis cylinder 373, the first lifting plate 374, the insulating block 375 and the detection pressure plate 376 are all provided in two sets and correspond to the front and rear sides of the first mounting base 372.

[0038] The X-axis drive assembly 31 drives the movable bracket 32 ​​to move laterally, and the Z-axis drive assembly 33 drives the transfer device 34 to rise and fall. The suction cups on the adsorption plate 342 grab the battery from the previous process and move the battery to the positioning platform 36. During this process, the tab pressure plates 345 are all above the battery tabs. After the battery is placed on the positioning platform 36, the first Z-axis cylinder 373 drives the detection pressure plate 376 to rise. It cooperates with the tab pressure plate 345 to press the battery tabs firmly onto the detection pressure plate 376 below. The two sets of detection pressure plates 376 are connected to the two sets of tabs respectively. The detection pressure plates 376 collect voltage signals to complete the detection. The transfer and detection are completed in one integrated process, without the need for the detection platform to move back and forth separately. The adsorption plate 342, the horizontal adjustment plate 343, and the vertical adjustment plate 344 can be finely adjusted in the front-back, left-right, and vertical directions respectively to adapt to batteries of different sizes. The advantage of this design is that the material transfer device 34 integrates the dual functions of adsorption and material handling and electrode pressing. While the suction cup picks up the battery and transfers it to the positioning platform 36, the electrode pressing plate 345 can directly press down on the electrode to complete the voltage detection. There is no need for the detection platform to move back and forth to the three stations of loading, detection and unloading, which greatly simplifies the detection process and improves the overall detection cycle.

[0039] The Z-axis drive assembly 33 includes a mounting plate 331, a second Z-axis cylinder 332, a second lifting plate 333, a third lifting plate 334, a mounting top plate 335, and a buffer spring 336. The lower end of the mounting plate 331 is fixed on the movable bracket 32. The second Z-axis cylinder 332 is fixed on the upper end of the mounting plate 331. The second lifting plate 333 is fixed on the power output end of the second Z-axis cylinder 332. The rear end of the third lifting plate 334 is slidably connected to the front end of the second lifting plate 333 and can slide in the vertical direction. The mounting top plate 335 is fixed on the upper end of the second lifting plate 333. The upper and lower ends of the buffer spring 336 are respectively fixed on the lower end surface of the mounting top plate 335 and the upper end surface of the third lifting plate 334. The rear end of the first connecting plate 341 is fixed on the front side of the third lifting plate 334.

[0040] The second Z-axis cylinder 332 drives the second lifting plate 333 to lift as a whole, which in turn drives the third lifting plate 334 and the material transfer device 34 to move down synchronously. When the adsorption plate 342 picks up and puts in the battery, the buffer spring 336 is compressed to generate a rebound buffer force to avoid damaging the battery.

[0041] The positioning platform 36 includes a second mounting base 361, a carrier plate 362, a front baffle 363, a Y-axis cylinder 364, a push plate 365, an X-axis cylinder, and a push block 366. The second mounting base 361 is fixed to the power output end of the Y-axis drive assembly 35. The carrier plate 362 is fixed above the second mounting base 361. The second connecting plate 371 is fixed to the left side of the second mounting base 361. The front baffle 363 is fixed to the upper front side of the carrier plate 362. The Y-axis cylinder 364 is fixed on the second mounting base 361. The push plate 365 is fixed to the power output end of the Y-axis cylinder 364 and corresponds to the rear side above the carrier plate 362. The X-axis cylinder is fixed on the second mounting base 361. The push block 366 is fixed to the power output end of the X-axis cylinder and corresponds to the right side above the carrier plate 362. The detection pressure plate 376 corresponds to the left side of the carrier plate 362.

[0042] After the battery is placed on the carrier plate 362, the Y-axis cylinder 364 drives the pusher plate 365 to push the battery forward, so that the front end of the battery is close to the front baffle 363 to complete the front-back positioning. The X-axis cylinder drives the pusher block 366 to push the battery to the left, so that the left side tab of the battery is accurately aligned with the position of the detection plate 376. The bidirectional pushing and positioning ensures that the tab is accurately placed above the detection plate 376, avoiding the tab offset from causing poor detection contact or misjudgment.

[0043] The Z-axis drive assembly 33 and the material transfer device 34 are arranged side by side on the movable bracket 32 ​​in the left and right directions, and the positioning platform 36 and the detection device 37 are arranged side by side on the power output end of the Y-axis drive assembly 35 in the left and right directions.

[0044] With dual-station synchronous operation, the X-axis drive component 31 can simultaneously pick up and place two sets of batteries and perform testing with one lateral movement. The two positioning platforms 36 are positioned synchronously, and the two testing devices 37 collect voltage synchronously. The testing efficiency is doubled compared to the single-station system, meeting the testing cycle requirements of high-speed mass production lines.

[0045] The packaging sub-machine 4 includes a worktable 41, a conveyor platform mechanism 42, an upper packaging mechanism 43, and a lower packaging mechanism 44. The conveyor platform mechanism 42 includes a first Y-axis drive component 421, a sliding middle plate 422, a battery platform 423, and a skirt platform 424. The first Y-axis drive component 421 is fixed to the front side of the worktable 41 with its power output end facing the rear side. The sliding middle plate 422 is fixed to the power output end of the first Y-axis drive component 421 and is slidably connected to the worktable 41. The sliding middle plate 422 is provided with a packaging cavity. The battery platform 423 and the skirt platform 424 are both... Fixed within the heat-sealing cavity, a gap exists between the front side of the skirt platform 424 and the rear side of the battery platform 423. The upper packaging mechanism 43 includes a first Z-axis drive component 431, a packaging upper plate 432, a first lifting cylinder 433, a second lifting cylinder 434, a third lifting cylinder 435, a battery pressure plate 436, an upper heat-sealing block 437, a skirt pressure plate 438, and a piercing component 439. The first Z-axis drive component 431 is mounted above the rear side of the worktable 41 with its power output end facing downwards. The packaging upper plate 432 is fixed to the power output end of the first Z-axis drive component 431. The upper packaging cavity is located below. First lifting cylinders 433, second lifting cylinders 434, and third lifting cylinders 435 are sequentially fixed to the upper packaging plate 432 from front to back. Battery pressure plate 436, upper heat-sealing block 437, and skirt pressure plate 438 are sequentially fixed to the power output ends of the first lifting cylinder 433, the second lifting cylinder 434, and the third lifting cylinder 435, respectively. The battery pressure plate 436, upper heat-sealing block 437, and skirt pressure plate 438 all correspond to the upper packaging cavity. A piercing component 439 is fixed to the upper packaging plate 432 and has a piercing end at its lower end. The bayonet 4395 is provided above the skirt pressure plate 438. The lower packaging mechanism 44 includes a second Z-axis drive component 441, a lower packaging plate 442, a fourth lifting cylinder 443, and a lower heat sealing block 444. The second Z-axis drive component 441 is fixed below the worktable 41 with its power output end facing upward. The lower packaging plate 442 is fixed to the power output end of the second Z-axis drive component 441 and has a lower packaging cavity on its upper part. The fourth lifting cylinder 443 is fixed on the lower packaging plate 442. The lower heat sealing block 444 is fixed to the power output end of the fourth lifting cylinder 443 and corresponds to the lower packaging cavity.

[0046] In the initial state, the first Y-axis drive component 421 drives the sliding middle plate 422 to extend forward outside the equipment. The robot arm of the previous process places the soft-pack battery body on the battery carrier 423, while the aluminum-plastic film skirt of the battery is placed on the skirt carrier 424. The first Y-axis drive component 421 drives the sliding middle plate 422 to move backward and send it into the packaging station in the middle of the upper and lower packaging mechanism 44. The first Z-axis drive component 431 drives the upper packaging plate 432 to descend. First, the first lifting cylinder 433 drives the battery pressure plate 436 to press down and tighten the battery body. The third lifting cylinder 435 drives the skirt pressure plate 438 to press down and clamp the aluminum-plastic film skirt, fixing and limiting the skirt to prevent the skirt from shifting when punctured. Simultaneously, the second Z-axis drive component 441 drives the lower packaging plate 442 to rise. The upper packaging plate 432 and the lower packaging plate 442 seal the upper and lower ends of the packaging cavity, respectively. A vacuum is drawn into the packaging cavity by a vacuum pump. Then, the piercing blade 4395 descends and pierces the aluminum-plastic film skirt through the skirt pressure plate 438. Gas generated during battery formation and excess electrolyte are discharged from the pierced gap. The fourth lifting cylinder 443 drives the lower heat sealing block 444 to rise, and the second lifting cylinder 434 drives the upper heat sealing block 437 to press down. The upper and lower heat sealing blocks 444 are inserted into the gap and press against each other to squeeze the aluminum-plastic film skirt for high-temperature heat sealing, completing the secondary packaging of the battery. After the heat sealing and pressure holding are completed, all cylinders are lifted and reset in sequence. The first Y-axis drive component 421 drives the sliding middle plate 422 to extend forward again. The subsequent process robot takes out the packaged battery and repeats the packaging operation for the next group of batteries. The advantage of this design is that the upper packaging mechanism 43 is equipped with three sets of independent lifting cylinders, which control the battery pressure plate 436, the upper heat sealing block 437, and the skirt pressure plate 438 respectively. The battery pressing, skirt clamping, and heat sealing pressurization actions can be completed in steps, which can avoid skirt displacement during puncture and heat sealing, and improve the quality and efficiency of secondary packaging.

[0047] The battery platform 423 includes an adsorption platform 4231, a rear baffle 4232, a second Y-axis drive component 4233, and a pusher plate 4234. The adsorption platform 4231 is fixed inside the encapsulation cavity and has a gap between its rear end and the skirt platform 424. The rear baffle 4232 is fixed above and behind the adsorption platform 4231. The second Y-axis drive component 4233 is fixed on the sliding plate 422 and its power output end corresponds to the encapsulation cavity. The pusher plate 4234 is fixed to the power output end of the second Y-axis drive component 4233 and corresponds to the front side of the rear baffle 4232.

[0048] After the battery body is placed on the adsorption platform 4231, the adsorption structure adsorbs the bottom surface of the battery. The second Y-axis drive component 4233 drives the push plate 4234 to push the battery backward, so that the rear end of the battery body fits against the rear baffle 4232, realizing bidirectional positioning of the battery. The battery will not move back and forth during the entire encapsulation process, ensuring that the skirt puncture and heat sealing positions are always accurately matched.

[0049] The piercing component 439 includes a fifth lifting cylinder 4391, a first connecting block 4392, a lifting rod 4393, a second connecting block 4394, and a bayonet 4395. The fifth lifting cylinder 4391 is fixed above the upper packaging plate 432 with its power output end facing upward. The rear end of the first connecting block 4392 is fixed on the power output end of the fifth lifting cylinder 4391. The middle part of the lifting rod 4393 is slidably connected to the upper packaging plate 432. The upper end of the lifting rod 4393 is fixed to the front side of the first connecting block 4392. The lower end of the lifting rod 4393 corresponds to the upper packaging cavity and is fixed to the rear end of the second connecting block 4394. The upper end of the bayonet 4395 is fixed to the front end of the second connecting block 4394, and the lower end passes through the skirt pressure plate 438. Multiple sets of bayonets 4395 are provided on the second connecting block 4394.

[0050] After the skirt plate 438 is pressed down and clamps the aluminum-plastic film skirt in advance, the fifth lifting cylinder 4391 drives the lifting rod 4393 to push down multiple sets of piercing blades 4395, which pierce the aluminum-plastic film through the skirt plate 438. The gas and electrolyte inside the battery flow out from the pierced gap. The outflowing electrolyte is collected uniformly through the collection port on the skirt platform 424. After the piercing is completed, the cylinder lifts the piercing blades 4395 and then starts the heat sealing process. The simultaneous piercing by multiple sets of piercing blades 4395 ensures that the gas and liquid are fully discharged.

[0051] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the technical scope of the present invention.
