Description

Technical Field

[0001] This invention relates to a packaging film disassembly device, and more specifically, to a disassembly opening device for aluminum-plastic film of soft-pack batteries. Background Technology

[0002] The structure of a pouch battery, from the outside in, consists of an outer packaging paper, an aluminum-plastic film, and a battery cell composed of a positive electrode, a separator, and a negative electrode. In existing pouch battery recycling processes, the entire battery is typically crushed first, and then the crushed materials are separated using different sorting devices. This recycling method inevitably leads to some mixing of materials, resulting in reduced purity and affecting subsequent recycling. To avoid these problems, a new recycling method is adopted: first, the pouch battery is disassembled and its components are separated before crushing it for recycling.

[0003] The disassembly process for pouch batteries involves first tearing off the outer packaging paper and aluminum-plastic film, then removing the internal battery cell composed of the positive and negative electrode plates and the separator. The cell is then unfolded to separate the positive and negative electrode plates and the separator for separate recycling. In the current recycling process, the aluminum-plastic film is manually opened by flipping open the seals at both ends and cutting them with scissors to create openings for removing the battery cell. This method of removing the aluminum-plastic film requires a large amount of manpower and is inefficient, impacting the overall efficiency of the battery recycling process. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a compact and automated opening device for disassembling aluminum-plastic film on soft-pack batteries.

[0005] The technical solution of the present invention is implemented as follows: a disassembly and opening device for aluminum-plastic film of soft-pack battery includes an installation platform, a horizontal conveyor belt on the installation platform, an installation bracket on the horizontal conveyor belt, and a lifting component on the installation bracket; a horizontal pressure plate is connected to the lifting component through an elastic component.

[0006] Slide grooves are provided on both sides of the bottom of the horizontal pressure plate along the direction perpendicular to the horizontal conveyor belt. Push shovels for pushing open the flipped edges of the aluminum-plastic film of the battery are provided in the slide grooves. Linkage drive components for driving the push shovels on both sides are provided on the horizontal pressure plate.

[0007] A horizontal drive assembly is provided on the mounting brackets on both sides perpendicular to the conveying direction of the horizontal conveyor belt. The horizontal drive assembly is provided with an alignment push block for clamping the soft-pack battery. An alignment assembly that cooperates with the soft-pack battery is provided on the horizontal pressure plate on both sides along the conveying direction of the horizontal conveyor belt. A cutting assembly is provided on the alignment push block. A clearance cutting hole that cooperates with the cutting assembly is provided on the push shovel.

[0008] In the above-mentioned disassembly opening device for aluminum-plastic film of soft-pack battery, the elastic component includes an installation cylinder connected to the lifting component, a connecting rod for connecting a horizontal pressure plate is slidably arranged inside the installation cylinder, and a buffer spring is provided between the connecting rod and the bottom surface of the installation cylinder.

[0009] In the above-mentioned soft-pack battery aluminum-plastic film disassembly opening device, the linkage drive component includes a hinge shaft disposed on the elastic component and parallel to the conveying direction of the horizontal conveyor belt, the pusher is provided with a hinge seat, and a guide groove that cooperates with the hinge seat is provided on the horizontal pressure plate.

[0011] A slot adapted to the push bar is provided at the bottom of the mounting bracket, and a positioning step is provided near the front end of the push bar; when the push bar blade is in the slot, the positioning step fits against the surface of the mounting bracket and makes way for the cutting hole to align with the cutting groove.

[0012] In the above-mentioned soft-pack battery aluminum-plastic film disassembly opening device, the alignment component includes a baffle plate disposed at the bottom of one end of the horizontal pressure plate in the conveying direction of the horizontal conveyor belt, and an integrally formed mounting plate in the shape of "┐" on the horizontal pressure plate opposite to the baffle plate. A push plate is connected to the vertical section of the mounting plate by a horizontal cylinder and a guide rod. A rubber pad is provided at the front end of both the baffle plate and the push plate.

[0013] With the above-described structure, the recycled batteries to be de-aerated from their aluminum-plastic film are conveyed to a horizontal pressure plate via a horizontal conveyor belt. The alignment assembly and alignment pusher sequentially push the batteries to the predetermined cutting positions. The horizontal pressure plate holds the batteries in place, and a pusher pushes open the two ends of the aluminum-plastic film, which is then cut by the cutting assembly for easy removal of the battery cells. This invention enables automated opening of the aluminum-plastic film on the batteries, reducing labor costs and effectively improving battery recycling efficiency.

[0024] See Figure 1-7 As shown, the present invention discloses a disassembly and opening device for aluminum-plastic film of a soft-pack battery, comprising an installation platform 1, a horizontal conveyor belt 2 on the installation platform 1, an installation bracket 3 on the horizontal conveyor belt 2, and a lifting assembly 4 on the installation bracket 3; a horizontal pressure plate 6 is connected to the lifting assembly 4 via an elastic component 5. After the recycled battery has its packaging paper torn off, the aluminum-plastic film is placed on the horizontal conveyor belt with the flipped edges facing upwards for conveying, and the flipped edges of the aluminum-plastic film are respectively located on both sides perpendicular to the conveying direction of the horizontal conveyor belt.

[0025] Slide grooves 7 are provided on both sides of the bottom of the horizontal pressure plate 6 along the conveying direction perpendicular to the horizontal conveyor belt 2. Push shovels 8 are provided in the slide grooves 7 for pushing open the flanges at both ends of the aluminum-plastic film of the battery. A linkage drive assembly 9 is provided on the horizontal pressure plate 6 for driving the push shovels 8 on both sides. The battery is fixed by pressing it down by the horizontal pressure plate, and the bottom surface of the push shovel is in close contact with the surface of the battery, so that the blade-shaped front end of the push shovel can better insert into the gap at the flanges at both ends of the aluminum-plastic film to push it open.

[0026] Horizontal drive assemblies 10 are provided on mounting brackets 3 on both sides perpendicular to the conveying direction of the horizontal conveyor belt 2. Alignment pushers 11 for clamping soft-pack batteries are provided on the horizontal drive assemblies 10. Alignment assemblies 12 that cooperate with the soft-pack batteries are provided on the horizontal pressure plates 6 on both sides along the conveying direction of the horizontal conveyor belt 2. Cutting assemblies 13 are provided on the alignment pushers 11, and clearance cutting holes 14 that cooperate with the cutting assemblies 13 are provided on the pusher 8. The length of the alignment pusher is not less than the length of the battery. When the alignment pusher clamps the battery, the battery is located directly below the horizontal pressure plate, and both ends of the battery are flush with the forward direction of the horizontal conveyor belt. To reduce damage to the battery caused by excessive force during clamping, rubber pads or similar cushioning devices can be provided at the front end of the alignment pusher.

[0027] The battery is pushed to the predetermined cutting position by the alignment component and the alignment pusher in sequence. The battery is fixed by pressing it down with the horizontal pressure plate, and the bottom surface of the pusher is made to be close to the surface of the battery. The blade-shaped front end of the pusher can be better inserted into the gap at both ends of the aluminum-plastic film to push it open. After the two ends of the aluminum-plastic film are pushed onto the alignment pusher, they are cut by the cutting component.

[0028] If the pusher blade retracts after pushing open the aluminum-plastic film edge, the edge may curl and lift, affecting the cutting effect. A clearance cutting hole is provided on the pusher blade to work with the cutting component for cutting. During cutting, the pusher blade presses firmly against the aluminum-plastic film edge to prevent curling and lifting.

[0029] Each component is connected to the control terminal via corresponding sensors to ensure smooth operation between processes. The specific installation locations and structures of the sensors are common knowledge to those skilled in the art and will not be described in detail here.

[0030] In this embodiment, the elastic component 5 includes a mounting cylinder 5a connected to the lifting component 4. A connecting rod 5b for connecting to the horizontal pressure plate 6 is slidably disposed inside the mounting cylinder 5a. A buffer spring 5c ​​is provided between the connecting rod 5b and the inner bottom surface of the mounting cylinder 5a. The inner diameter of the mounting cylinder is larger than the diameter of the connecting rod. A piston head adapted to the inner diameter of the mounting cylinder is provided at the upper end of the connecting rod. A ring cap with an inner diameter adapted to the diameter of the connecting rod is threadedly connected to the open end of the mounting cylinder. This structure allows the connecting rod to be installed inside the mounting cylinder, ensuring stable installation while facilitating easy assembly and disassembly.

[0031] In this embodiment, the linkage drive assembly 9 includes a hinge shaft 9a disposed on the elastic assembly 5 and parallel to the conveying direction of the horizontal conveyor belt 2. The pusher 8 is provided with a hinge seat 9b, and the horizontal pressure plate 6 is provided with a guide groove 9c that cooperates with the hinge seat 9b. The hinge shaft 9a and the hinge seat 9b are connected by a connecting rod 9d. When the bottom surface of the horizontal pressure plate contacts the battery, it continues to press the battery downwards for fixation under the buffer of the elastic assembly. During this process, the hinge shaft pushes the connecting rod downwards, causing the pusher 9a to move outwards.

[0032] In this embodiment, the cutting assembly 13 includes a mounting suspension 13a disposed on the alignment push block 11, and a cutter 13c disposed on the mounting suspension 13a via a lifting cylinder 13b; a cutting groove 13d cooperating with the cutter 13c is provided on the alignment push block 11. The free end of the piston rod of the lifting cylinder is connected to a blade holder for mounting the cutter, and the blade holder is configured to cooperate with the mounting suspension via a guide rod and a sliding sleeve. A discharge assembly for discharging the aluminum-plastic film edge material cut by the cutting assembly is provided on the mounting platform. Its specific structure can adopt a common structure that is easily conceived by those skilled in the art, such as a blower nozzle disposed on one side of the cutting groove and a guide groove disposed on the opposite side.

[0033] The cutting groove is 0.5-0.8mm away from the end of the alignment push block, which is also the end of the battery. During multiple tests to select a suitable cutting position, it was found that when the cutting position is 0.5-0.8mm away from the end of the battery, the edge of the aluminum-plastic film that is being sealed can be completely cut off to open the opening completely without cutting into the internal battery cell.

[0034] A slot 13e adapted to the pusher 8 is provided at the bottom of the mounting suspension 13a, and a positioning step 13f is provided near the front end of the pusher 8. When the blade of the pusher 8 is in the slot 13e, the positioning step 13f fits against the surface of the mounting suspension 13a and the clearance cutting hole 14 is aligned with the cutting groove 13d. When the blade of the pusher is in the slot, the lifting cylinder pushes the cutter downward through the clearance cutting hole to cut off the ends of the aluminum-plastic film. The slot and positioning step ensure that the clearance cutting hole and the cutting groove are aligned after the pusher pushes open the aluminum-plastic film on pouch batteries of different sizes.

[0035] In this embodiment, the alignment component 12 includes a baffle 12a disposed at the bottom of the horizontal pressure plate 6 at one end of the horizontal conveyor belt 2 in the conveying direction. A "┐"-shaped mounting plate 12b is integrally formed on the horizontal pressure plate 6 opposite to the baffle 12a. A push plate 12d is connected to the vertical section of the mounting plate 12b via a horizontal cylinder 12c and a guide rod. Rubber pads 12e are provided at the front ends of both the baffle 12a and the push plate 12d. The cooperation between the baffle and the push plate pushes the battery to a suitable cutting position, ensuring that the two flanges remain parallel to the horizontal conveyor belt. The rubber pads on the front surfaces of the baffle and the push plate provide cushioning to prevent damage to the battery from compression between them.

[0036] During operation, after the packaging paper of the recycled battery is torn off, the aluminum-plastic film is placed on the horizontal conveyor belt with the edge facing up for transport. When the battery moves to the predetermined cutting position under the horizontal pressure plate, the horizontal conveyor belt stops running. The lifting component moves down to make the bottom of the baffle contact the surface of the horizontal conveyor belt, and the horizontal cylinder pushes the push plate to push the battery into contact with the baffle.

[0037] Then the horizontal drive components on both sides drive the alignment push block to clamp the battery. At this time, the lifting component continues to descend to press the battery with the horizontal pressure plate and make the pusher move along the battery surface to push up the aluminum-plastic film to flip the edge.

[0038] When the two ends of the aluminum-plastic film are rolled up and pushed onto the alignment push block and the pusher blade is inserted into the slot, the lifting cylinder pushes the cutter downward through the clearance cutting hole to cut off the ends of the aluminum-plastic film.

[0039] The above-described embodiments are preferred embodiments of the present invention and are only used to facilitate the illustration of the present invention. They are not intended to limit the present invention in any way. Any person skilled in the art who makes local modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention shall still fall within the scope of the technical features of the present invention.
