Description

Technical Field

[0001] The invention belongs to the technical field of battery processing equipment, and relates to a plugboard assembly for forming diaphragm paper, and also relates to a diaphragm paper forming equipment having the plugboard assembly. Background Art

[0002] The function of battery separator paper in lithium-ion batteries is to separate the positive and negative electrode materials. The quality of the separator paper directly affects the safety performance and capacity of the battery. The bottom of the separator paper needs to be rolled up and then sealed with hot paper.

[0003] The ironing of diaphragm paper is actually very important. Once there is a problem with the ironing seal, even a very small crack will affect the normal use of the battery. At present, when the diaphragm paper is formed, it is usually necessary to fold the bottom of the diaphragm paper with a plug plate and then iron it.

[0004] For example, a Chinese patent with application number 201420849692.2 discloses a membrane paper roll forming structure, which aims to solve the problem that the bottom of the existing membrane paper is prone to holes after forming, which causes the membrane paper to leak after use. The utility model includes a bracket, a roll drive mechanism connected to the bracket, a roll rod is installed on the roll drive mechanism, a forming plate is provided below the roll rod, a limit plate and a forming block are provided on the forming plate, the forming block is arranged at the upper end of the limit plate, the limit plate is an arc structure, the side of the forming block close to the limit plate is an arc structure, and a T-shaped groove is formed between the two opposite side walls of the forming block and the limit plate, the T-shaped groove includes an upper positioning groove and a lower paper rubbing groove, the lower end of the roll rod is arranged in the positioning groove, the width of the paper rubbing groove gradually narrows from top to bottom, the upper ends of the limit plate and the forming baffle are both in a step-shaped structure, and the width of the lower step surface gradually increases from top to bottom; a heating device is installed on the forming plate near the lower end of the limit plate.

[0005] The above-mentioned diaphragm paper forming equipment discloses some components required for forming diaphragm paper. However, when the diaphragm paper is actually produced, it is necessary to fold it at the end position through a plug plate, and then the folded diaphragm paper end is ironed to form a sealed structure. The folding method of the diaphragm paper determines its sealing during ironing. The existing plug plate assembly cannot fold the diaphragm paper end well, which leads to the disadvantage of poor sealing of the diaphragm paper in subsequent production. Therefore, there is a certain room for improvement.

[0006] Furthermore, the diaphragm paper formed in large quantities by the above-mentioned diaphragm paper forming equipment still has poor sealing performance and low reliability, and there is room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0037] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4A , Figure 4B , Figure 5 , Figure 6 As shown, a plug plate assembly includes: a main board 200, a moving unit, a lifting unit and a double folding unit. The plug plate assembly is used in a membrane paper 100 forming device, and it is different from the plug plates in the existing forming equipment. The plug plate assembly can achieve more thorough folding and forming of the membrane paper 100, thereby making the membrane paper 100 more sealed, and can also greatly improve product quality and qualified rate.

[0039] It is worth explaining here that the battery diaphragm paper 100 plays a very important role in lithium-ion batteries, and the sealing of the diaphragm paper 100 is very important for the safety of the battery. At present, the battery diaphragm paper 100 needs to be folded at its ends during production before it can be ironed and sealed. However, the existing diaphragm paper 100 is only folded once when folding, and its ends are not completely folded and wrapped, so small cracks are easily generated during ironing, and the pass rate will also be affected.

[0040] Based on the above problems, in the present embodiment, there is provided a method for folding the diaphragm paper 100 multiple times, so that the end of the diaphragm paper 100 is formed into a wrapped structure. It is preferably folded twice, and folded once on both sides of the end of the diaphragm paper 100 respectively, so that the end of the diaphragm paper 100 is wrapped together. The sealing performance of the end of the diaphragm paper 100 with this shape can be greatly improved during ironing. That is to say, the defects of cracking or fissures are completely avoided after the end of the diaphragm paper 100 is formed after being folded twice.

[0041] Among them, the main board 200 is fixedly arranged; the main board 200 is used to be fixed on the membrane paper 100 forming equipment, and serves as the base of the moving unit and the lifting unit. In the actual structure, the main board 200 is tilted.

[0042] A moving unit is arranged on the main board 200; the moving unit is used to drive the double folding unit to move in the horizontal direction. Specifically, the double folding unit cannot fold both sides of the end of the diaphragm paper 100 at one time, and it is necessary to fold the diaphragm paper 100 twice to fold it into shape. After the first folding, the double folding unit needs to adjust its position through the moving unit and then perform the second folding.

[0043] The lifting unit is connected to the moving unit; the lifting unit is actually a component that drives the double folding unit to perform extrusion and folding, and the lifting unit is connected to the moving unit, so the lifting unit moves horizontally through the moving unit, and the lifting unit can drive the double folding unit to move up and down. Specifically, the lifting unit drives the double folding unit to descend, thereby squeezing one side of the end of the diaphragm paper 100 to fold it. When the folding is completed, the lifting unit rises, and the double folding unit is separated from the diaphragm paper 100.

[0044] A double folding unit is connected to the lifting unit. The double folding unit can fold one side of the end of the diaphragm paper 100 through the lifting unit. The moving unit can drive the double folding unit to move and fold the other side of the end of the diaphragm paper 100 through the lifting unit, so that the two sides of the end of the diaphragm paper 100 are folded toward the middle.

[0045] Preferably, the double folding unit is a component that folds the end of the diaphragm paper 100 by squeezing it. In the existing diaphragm paper 100 forming device, although there are components for folding the end of the diaphragm paper 100, these components are actually only folded once. That is to say, the existing forming device actually only squeezes one side of the end of the diaphragm paper 100, folds one side toward the other side, and then performs ironing. In this embodiment, the double folding unit can fold the end of the diaphragm paper 100 twice, that is, folds both sides of the end of the diaphragm paper 100 toward the middle, so that the end is completely wrapped to form a tighter sealing state. If ironing is performed at this time, the sealing can be greatly improved and defective products can be reduced.

[0046] In terms of working principle, the double folding unit is connected to the lifting unit, and the lifting unit is connected to the moving unit, so the lifting unit can drive the double folding unit to move up and down, thereby realizing the folding function, and the moving unit can drive the lifting unit and the double folding unit to move horizontally, thereby achieving the purpose of the second folding.

[0047] During the entire working process, the diaphragm paper 100 is located below the double folding unit, the lifting unit drives the double folding unit to descend, and makes the first folding component of the double folding unit squeeze and push one side of the diaphragm paper 100, then the lifting unit drives the double folding unit to rise, and then the moving unit drives the double folding unit to move, so that the second folding component of the double folding unit squeezes and pushes the other side of the diaphragm paper 100, and then the lifting unit drives the double folding unit to descend and fold the other side of the end of the diaphragm paper 100, so that the end of the diaphragm paper 100 forms a better sealing structure by folding on both sides.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, on the basis of the above embodiment, the double folding unit includes a pressure plate seat 310, a first plug plate 320 and a second plug plate 330, the pressure plate seat 310 is vertically arranged and connected to the lifting unit, the first plug plate 320 and the second plug plate 330 are respectively fixed on the front and rear sides of the pressure plate seat 310, the first plug plate 320 is used to fold one side of the end of the diaphragm paper 100, and the second plug plate 330 is used to fold the other side of the end of the diaphragm paper 100.

[0049] Preferably, the pressure plate seat 310 is used to fix the first plug plate 320 and the second plug plate 330, and to separate the first plug plate 320 and the second plug plate 330 by a certain distance. The pressure plate seat 310 is fixedly connected to the lifting unit, so the lifting unit can drive the pressure plate seat 310 to move up and down, thereby driving the first plug plate 320 and the second plug plate 330 to move up and down.

[0050] Preferably, the first plug plate 320 and the second plug plate 330 are both used to squeeze and fold the end of the diaphragm paper 100, and the first plug plate 320 and the second plug plate 330 are respectively fixed on the front and rear surfaces of the pressure plate seat 310, so that a certain distance is formed between the first plug plate 320 and the second plug plate 330. In the actual folding process, the first plug plate 320 is first aligned with the diaphragm paper 100, and the pressure plate seat 310 moves downward. After the first plug plate 320 folds one side of the diaphragm paper 100, the pressure plate seat 310 moves forward through the moving unit, so that the second plug plate 330 is aligned with the diaphragm paper 100, and then the pressure plate seat 310 moves downward, and the second plug plate 330 folds the other side of the diaphragm paper 100.

[0051] The above structure achieves a secondary folding effect through two separately arranged plug plates, and can fold both sides of the end of the diaphragm paper 100, thereby forming a finished diaphragm paper 100 with very high sealing performance.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, on the basis of the above embodiment, the moving unit includes a cylinder seat 410, a pushing cylinder 420 and a connecting plate 430, the cylinder seat 410 is fixed on the main board 200, the pushing cylinder 420 is arranged on the cylinder seat 410 and the piston rod of the pushing cylinder 420 can move horizontally, the connecting plate 430 is connected to the piston rod of the pushing cylinder 420, the lifting unit is connected to the connecting plate 430, and the second plug plate 330 can be moved to the end of the diaphragm paper 100 through the pushing cylinder 420.

[0053] Preferably, the cylinder seat 410 is a plate-like structure and is horizontally fixed on the main board 200, the pushing cylinder 420 is horizontally arranged on the cylinder seat 410, and the piston rod can be pushed forward, and the connecting plate 430 is an L-shaped structure, which is connected to the piston rod and the lifting unit. When the pushing cylinder 420 is working, the piston rod can push the connecting plate 430 to move forward, and finally the pressure plate seat 310 moves forward. When the pressure plate seat 310 moves forward, it can drive the second plug plate 330 to move forward, thereby realizing the second folding.

[0054] Preferably, the main purpose of the moving unit is to adjust the horizontal position of the pressure plate seat 310 so that the second plug plate 330 can be moved to the position of the diaphragm paper 100, and the working efficiency can be greatly improved by setting two plug plates and the moving unit. In addition, the method of driving the pressure plate seat 310 forward through the connecting plate 430 can make the first plug plate 320 away from the diaphragm paper 100 to avoid interfering with the second folding.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, on the basis of the above embodiment, the lifting unit includes a pull rod 510 and a guide positioning plate 520, a strip groove 411 is opened on the cylinder seat 410, and a guide hole 521 is opened on the guide positioning plate 520. The pull rod 510 passes through the strip groove 411 and the guide hole 521 and is fixedly connected to the pressure plate seat 310, and the guide positioning plate 520 is fixedly connected to the connecting plate 430. The pull rod 510 can drive the pressure plate seat 310 to move up and down, and the connecting plate 430 can drive the pressure plate seat 310 to move forward and backward through the guide positioning plate 520.

[0056] Preferably, the lifting unit includes a pull rod 510 and a guide positioning plate 520. The guide positioning plate 520 can move forward and backward through the connecting plate 430, and the pull rod 510 passes through the guide hole 521 of the guide positioning plate 520. Therefore, when the guide positioning plate 520 moves, it can drive the pull rod 510 to move forward and backward, and the pull rod 510 drives the pressure plate seat 310 to move forward and backward. In addition, the pull rod 510 itself can also move up and down, thereby pulling the pressure plate seat 310 to rise and fall.

[0057] Preferably, the pull rod 510 itself can move up and down, and can also be driven by the guide positioning plate 520 and move along the strip groove 411, and the pressure plate seat 310 is fixedly connected to the pull rod 510, so it can move horizontally and up and down, and finally drive the first plug plate 320 and the second plug plate 330 to fold the two sides of the end of the diaphragm paper 100 respectively.

[0058] like Figure 1 , Figure 2 , Figure 5 As shown, based on the above embodiment, a slider 412 is provided on the cylinder seat 410, and a slide rail 522 is provided on the guide positioning plate 520. The slide rail 522 is arranged in the slider 412 so that the guide positioning plate 520 is slidably connected to the cylinder seat 410.

[0059] Preferably, the slider 412 is disposed on the lower surface of the cylinder seat 410, and the slide rail 522 is disposed in the slider 412, so that the guide positioning plate 520 can slide along the slider 412 and can move accurately, so that the second plug plate 330 can move to the set position more accurately.

[0060] like Figure 1 , Figure 2 , Figure 3 As shown, on the basis of the above embodiment, the first plug plate 320 and the second plug plate 330 both include a plate body 340 and a forming tooth 350, the forming tooth 350 is arranged below the plate body 340, and extrusion parts 351 for folding the diaphragm paper 100 are arranged on both sides of the forming tooth 350, and the forming teeth 350 on the first plug plate 320 and the forming teeth 350 on the second plug plate 330 are arranged in a staggered manner.

[0061] Preferably, the first plug plate 320 and the second plug plate 330 have the same structure, and the number of the forming teeth 350 is multiple, and the multiple forming teeth 350 are evenly spaced below the plate body 340, so the first plug plate 320 and the second plug plate 330 can form multiple diaphragm papers 100 at one time, and the efficiency is very high; and one forming tooth 350 has two extrusion parts 351, that is, two diaphragm papers 100 are located on both sides of the forming tooth 350, and the sides of the diaphragm papers 100 are folded by the two extrusion parts 351, thereby greatly improving the production efficiency.

[0062] In addition, the forming teeth 350 on the first plug plate 320 and the forming teeth 350 on the second plug plate 330 are actually arranged in an alternating manner. That is to say, for a diaphragm paper 100, the forming teeth 350 on the first plug plate 320 are folded on one side by the extrusion portion 351, and then the second plug plate 330 moves forward. At this time, the extrusion portion 351 of the forming teeth 350 on the second plug plate 330 is just aligned with the other side of the diaphragm paper 100. Its structure is very clever. The staggered forming teeth 350 on the two plug plates are used to simplify the movement trajectory of the pressure plate seat 310, so that it only needs to move forward and backward to achieve the folding of the two ends of the diaphragm paper 100.

[0063] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, a membrane paper 100 forming device has a plug-in plate assembly, including: a feeding assembly, a clamping assembly and a heating assembly, which can achieve the membrane paper 100 forming effect, and after the forming device has the plug-in plate assembly, the membrane paper 100 can be folded twice, so that the end portions are folded and wrapped more tightly, which greatly improves the sealing performance. If the twice folded membrane paper 100 is ironed, the sealing performance of the ironed joint is very good, no gaps will appear, and the qualified rate is also greatly improved.

[0064] Among them, the feeding component is used to transfer the tubular diaphragm paper 100; it is worth explaining here that the diaphragm paper 100 is a tubular structure, which needs to be processed into a finished diaphragm paper 100 with one end closed, that is, one end of the diaphragm paper 100 needs to be sealed. Usually, during processing, one side of the diaphragm paper 100 is pressed and folded, and then heated and shaped by a heating component, so that one end of the diaphragm paper 100 forms a spherical or arc-shaped sealed end, and the folding step before ironing has a great influence on its sealing. Before folding, the diaphragm paper 100 is generally discharged and transported by the feeding component, so that the diaphragm paper 100 is arranged and then transported to the clamping component.

[0065] The clamping assembly is used to receive the diaphragm paper 100 transferred by the feeding assembly. The plug assembly is arranged above the clamping assembly, and the end of the diaphragm paper 100 is folded into shape by the first plug board 320 and the second plug board 330; the clamping assembly is actually a component that fixes the diaphragm paper 100 and drives it to the bottom of the first plug board 320, and when the diaphragm paper 100 is folded, the diaphragm paper 100 is brought to the bottom of the heating assembly for heating.

[0066] A heating component is arranged above the clamping component, and is used to iron the end of the diaphragm paper 100 on the clamping component and form a sealing structure at the end of the diaphragm paper 100.

[0067] Preferably, the heating assembly is actually a plurality of heating heads corresponding to the diaphragm paper 100 one by one, and the heating heads touch the ends of the folded diaphragm paper 100 to melt it and shape it into a sealed end.

[0068] like Figure 1 , Figure 5 , Figure 6As shown, on the basis of the above embodiment, the clamping assembly includes a rotating seat 610, a plurality of clamping parts 620 are arranged on the rotating seat 610, a plurality of positioning pins 621 arranged in a straight line are arranged on the clamping parts 620, the feeding assembly puts the diaphragm paper 100 on the positioning pins 621, the rotating seat 610 drives the diaphragm paper 100 to the bottom of the plug plate assembly for folding and forming by rotation, and the rotating seat 610 drives the formed diaphragm paper 100 to the heating assembly for ironing by rotation.

[0069] Preferably, the clamping assembly includes a rotatable rotating seat 610, and a plurality of clamping parts 620 are arranged in a circular shape on the rotating seat 610, which can greatly improve the working efficiency and ensure uninterrupted feeding. The clamping part 620 includes positioning pins 621 in a row, and the diaphragm paper 100 can be sleeved on the positioning pins 621.

[0070] During the specific working process, a clamping portion 620 on the rotating seat 610 is in a horizontal state, that is, a row of positioning pins 621 is arranged horizontally, so the diaphragm paper 100 can be sleeved on the positioning pins 621, and then the rotating seat 610 is rotated so that the positioning pins 621 face upward, and the other row of positioning pins 621 is rotated to a horizontal setting, and the subsequent diaphragm paper 100 is sleeved on the positioning pins 621, and the diaphragm paper 100 on the vertical positioning pins 621 is driven by the rotating seat 610 to the bottom of the heating component for ironing after the first plug plate 320 and the second plug plate 330 are folded. At the same time, the subsequent positioning pins 621 drive the newly installed diaphragm paper 100 to the bottom of the plug plate assembly, which can greatly improve the work efficiency and each step can be carried out simultaneously.

[0071] like Figure 1 , Figure 5 , Figure 6 As shown, based on the above embodiment, the feeding assembly includes a vibration plate 710 and a conveyor belt 720, the vibration plate 710 is connected to the conveyor belt 720, and a plurality of conveying grooves 721 are arranged on the conveyor belt 720, the conveying grooves 721 are arranged toward the positioning pins 621, and the plurality of conveying grooves 721 correspond one by one to the plurality of positioning pins 621.

[0072] Preferably, the feeding assembly includes a vibration plate 710 and a conveyor belt 720 . The vibration plate 710 can continuously convey the diaphragm paper 100 to the conveyor belt 720 , and the conveying groove 721 can arrange the diaphragm paper 100 to facilitate the diaphragm paper 100 to be loaded onto the positioning pin 621 .

[0073] like Figure 5 , Figure 6As shown, on the basis of the above embodiment, the clamping assembly includes a containing box 630 arranged between the conveyor belt 720 and the vibration plate 710, a partition 640 is arranged between the containing box 630 and the conveyor belt 720, and a push plate 650 that can be raised and lowered is arranged in the containing box 630, the conveyor belt 720 is connected to the containing box 630 and conveys the diaphragm paper 100 into the containing box 630, and the push plate 650 pushes the diaphragm paper 100 to turn over the partition 640 and fall onto the conveyor belt 720.

[0074] Preferably, since the diaphragm paper 100 on the conveyor belt 720 needs to be arranged in a straight line, the diaphragm paper 100 sent out from the vibration plate 710 is arranged in a straight line, and the diaphragm paper 100 is accommodated by the accommodating box 630 and then ejected by the push plate 650. At this time, only the diaphragm paper 100 arranged vertically can be ejected, and the horizontal diaphragm paper 100 cannot be ejected from the accommodating box 630. This has the effect of aligning the diaphragm paper 100, so that the diaphragm paper 100 that falls onto the conveyor belt 720 is arranged vertically.

[0075] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
