Description

Technical Field

[0002] Die cutting is a cutting process for the post-processing of new energy battery cells. The die cutting process can be made into a die cutting knife plate according to a pre-designed pattern for cutting, so that the shape of the product is no longer limited to straight edges and right angles. Under the action of pressure, the plate blank is rolled and cut into the required shape or cut mark.

[0003] In actual production, cutting through all the battery electrodes on the conveyor belt will damage the belt surface of the conveyor belt. After the conveyor belt surface is damaged, the battery electrodes placed on it will be uneven, resulting in insufficient die-cutting accuracy and affecting production quality. In order to prevent this from happening, the battery electrodes are often not completely cut through during die cutting, leaving an indentation. After the die-cut battery electrodes are transported out of the die-cutting machine through the conveyor belt, they are manually knocked into the material frame by hand. This production method requires manual work, and the battery electrodes that fall into the material frame are relatively scattered. The battery electrodes need to be manually arranged in order in the next production process, which affects work efficiency and is not conducive to the production of the next process.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2 As shown, one embodiment of the utility model includes a conveyor belt 2 and a reel 3. In current actual production, the reel 3 is horizontally arranged at one end of the conveyor belt 2. The conveyor belt 2 runs through the die-cutting machine 1. A whole sheet of battery electrodes is laid on the conveyor belt 2. The whole sheet of battery electrodes is die-cut into multiple independent battery electrodes by the back of the die-cutting machine 1. The staff stands between the conveyor belt 2 and the reel 3, puts a collection box on the ground, and uses tools or hands to press the die-cut battery electrodes from the whole sheet of battery electrodes into the collection box and transport them to the next process. The edges of the discarded battery electrodes and the waste after die-cutting are wound and collected by the reel 3. However, the battery electrodes knocked off in this way are relatively scattered, and need to be pressed continuously by humans. Once the workers leave their posts, the machine has to stop running.

[0030] In order to solve the inconvenience of manual work, such as Figures 1 to 5 As shown, the coiler 3 is fixedly mounted on the bracket 21, and a material distribution assembly is also mounted on the bracket 21. The material distribution assembly is provided with a fixing plate 4, and the fixing plate 4 is fixedly connected to a side wall of the bracket 21 by bolts. A telescopic cylinder 42 is fixedly mounted on the side wall of the fixing plate 4, a pressure strip 421 is welded on the telescopic cylinder 42, and a rubber column 422 is bonded to a side wall opposite to the pressure strip 421 and the fixing plate 4.

[0031] Specifically, after the battery electrode transported from the conveyor belt 2 passes through the space between the fixed plate 4 and the pressure strip 421, one end is wound by the coiler 3. At this time, the telescopic cylinder 42 reciprocates and moves, driving the pressure strip 421 and the rubber column 422 to move, so that the rubber column 422 continuously presses on the battery electrode transported by the conveyor belt 2, and the die-cut battery electrode can be pressed down to achieve the separation of the battery electrode.

[0032] Specifically, when the pressing knife of the die-cutting machine 1 presses down the battery electrode sheet on the conveyor belt 2, the telescopic cylinder 42 also contracts inward, driving the pressure strip 421 and the rubber column 422 to move toward the fixed plate 4, thereby pressing out the cut battery electrode sheet connected to the whole battery electrode sheet. It is separated from the whole battery electrode sheet. After separation, the whole battery electrode sheet is only waste material, which is wound and collected by the coiler 3.

[0033] like Figures 3 to 5 As shown, in order to separate the pressed battery pole pieces from the waste and neatly drop them into the collection box, a pair of bearing plates 411 are welded on one side wall of the bearing frame 41, and the pair of bearing plates 411 are respectively on both sides of the pressure strip 421. A second clamping plate 413 is bonded to the inner side of the bearing plate 411, and a sleeve 4111 is welded to the outer side. A sliding rod 4112 is slidably connected in the sleeve 4111, and the sliding rod 4112 penetrates the sleeve 4111, the bearing plate 411 and the second clamping plate 413 and is bonded to 412. The sliding rod 4112 can slide linearly in the sleeve 4111.

[0034] When the sliding rod 4112 specifically slides in the sleeve 4111, it will drive the first clamping plate 412 to make a linear motion, so that the distance between the first clamping plate 412 and the second clamping plate 413 can be controlled. One end of the battery electrode sheet transported from the conveyor belt 2 passes through between the first clamping plate 412 and the second clamping plate 413 and is wound on the reel 3. Pulling the sliding rod 4112 allows the first clamping plate 412 and the second clamping plate 413 to limit and clamp the battery electrode sheet to prevent the edge of the waste battery electrode sheet from bending when the rubber column 422 presses the battery electrode sheet, resulting in the battery electrode sheet after cutting not being able to fall off the waste material due to the force. The side wall of the first clamping plate 412 away from the battery electrode sheet also forms a space for material leakage with the side wall of the fixed plate 4.

[0035] It is worth noting that the force of the first clamping plate 412 and the second clamping plate 413 to clamp the waste of the cut battery pole piece should not be too large, and it is necessary to ensure that the waste can slide between the first clamping plate 412 and the second clamping plate 413. The material of the first clamping plate 412 and the second clamping plate 413 is polytetrafluoroethylene, which has a small friction coefficient.

[0036] Specifically, because the first clamping plate 412 blocks the entire battery electrode sheet and the fixing plate 4, and there is a gap between the first clamping plate 412 and the fixing plate 4, the divided battery electrode sheets pressed by the rubber column 422 can fall downward from the gap between the first clamping plate 412 and the fixing plate 4 under the pressure strip 421 under the action of gravity. The second clamping plate 413 disposed under the pressure strip 421 can not only separate the battery electrode sheets from the waste, but also play a limiting role, so that the fallen battery electrode sheets fall in a vertical direction.

[0037] Furthermore, the gap between the first clamping plate 412 and the fixed plate 4 is directly below the conveyor belt 2. In this way, even if the battery electrode completely cut off by the die-cutting machine detaches from the belt surface of the conveyor belt 2, it can fall from the gap between the first clamping plate 412 and the fixed plate 4.

[0038] In order to fix the position of the first clamping plate 412, a soft rubber layer is wrapped on one end of the sliding rod 4112. When the sliding rod 4112 slides in the sleeve 4111, there is friction. The sliding rod 4112 will slide in the sleeve 4111 only when the sliding rod 4112 is pulled or pressed hard, and will not slide in the sleeve 4111 due to vibration or contact. In this way, the distance between the first clamping plate 412 and the fixed plate 4 can be adjusted according to the thickness of the battery electrode.

[0039] A material guide trough 5 is welded on the lower panel of the fixed plate 4, and a movable material receiving box 6 is arranged at the lower end of the material guide trough 5. The lower part of the material guide trough 5 is an inclined structure, and the inner wall of the vertical part of the material guide trough 5 is flush with the side wall of the fixed plate 4. The battery pole piece dropped from the space between the first clamping plate 412 and the fixed plate 4 passes through the material guide trough 5, and falls into the material receiving box 6 after being guided by the material guide trough 5.

[0040] like Figure 6 As shown, in order to allow the fallen battery electrodes to fall neatly into the material receiving box 6, a plurality of first dividing strips 51 are adhered to the inner wall of the material guiding trough 5, and the first dividing strips 51 divide the material guiding trough 5 into a plurality of independent material guiding channels. A second dividing strip 61 matching the first dividing strip 51 is movably inserted into the material receiving box 6.

[0041] Specifically, the first separator bar 51 installed on the inner wall of the guide groove 5 matches the rubber column 422, and the rubber column 422 is located between the two first separator bars 51. According to the different sizes of battery pole pieces cut according to the process requirements, the position of the first separator bar 51 in the guide groove 5 can be adjusted to facilitate the export of battery pole pieces of different widths.

[0042] Furthermore, the distance between the first dividing strips 51 is set to be larger at the connection near the fixed plate 4 and smaller near the material receiving box 6. This not only makes it more convenient to catch the battery electrodes that fall from the space between the fixed plate 4 and the first clamping plate 412, but also makes the derived battery electrodes more neat when they fall into the material receiving box 6.

[0043] The bend of the guide slot 5 is set to an open structure, and only the vertical part of the guide slot 5 is provided with a cover plate, which plays a role in limiting the battery pole pieces falling into the guide slot 5, so that the battery pole pieces can fall vertically. The open structure at the bend can prevent the battery pole pieces from being stuck when changing the falling direction and turning, and can slide smoothly into the receiving box 6.

[0044] like Figure 2 and Figure 7 As shown, the material receiving box 6 is placed between the bracket 21 and the die-cutting machine 1. This can save space on the production line and prevent workers walking back and forth from accidentally stepping on or touching the material receiving box 6, causing the material receiving box 6 to shift and fail to receive the material discharged from the material guide trough 5.

[0045] Furthermore, a universal wheel is installed under the receiving box 6, so that when the receiving box 6 is full, the receiving box 6 can be easily replaced. After the receiving box 6 filled with battery pole pieces is transferred to the next process, the second partition bar 61 inserted in the receiving box 6 can be pulled out to facilitate taking out the battery pole pieces in the receiving box 6.

[0046] When in use, the rolled battery electrode sheet is placed on the unwinder (not shown in the figure), and the battery electrode sheet pulled out from the unwinder is laid on the conveyor belt 2, and is pulled from the feeding end of the die-cutter 1 to the discharging end of the die-cutter 1, and then passes through the gap between the first clamping plate 412 and the second clamping plate 413, and is wound on the coiler 3 after being limited by the first clamping plate 412 and the second clamping plate 413. The die-cutter 1 is started, and the die-cutter 1 cuts the battery electrode sheet on the conveyor belt 2, and after cutting, it is divided into a plurality of block battery electrode sheets. At this time, a number of blocked battery electrodes are hung in the waste frame of the battery electrodes, and the telescopic cylinder 42 drives the rubber column 422 to reciprocate, pressing the blocked battery electrodes passing between the rubber column 422 and the side wall of the fixed plate 4 out of the waste frame and pushing them to the side wall of the fixed plate 4. From the gap between the fixed plate 4 and the first clamping plate 412, they fall into the material guide trough 5 under the action of gravity, and finally fall into the material receiving box 6 after being guided by the material guide trough 5, and the waste frame is wound and collected by the coiler 3.

[0047] Because before each use, it is necessary to pull out a distance and wind one end of the battery electrode on the winder 3, so that the battery electrode between the winder 3 and the die-cutting machine 1 cannot be cut and waste. In order to prevent this from happening, when the unwinder releases the battery electrode, a piece of cloth strip is glued to one end of the battery electrode, and the other end of the adhesive strip passes through the gap between the first clamping plate 412 and the second clamping plate 413 and is then wound on the winder 3. In this way, there will be no waste of battery electrodes, and the cloth strip has low cost and can be reused without causing waste of resources.
