Description

Technical Field

[0001] This invention belongs to the technical field of square aluminum-cased battery manufacturing equipment, and particularly relates to a square aluminum-cased battery flipping and film-applying machine. Background Technology

[0002] During the manufacturing process of square aluminum-cased batteries (hereinafter referred to as batteries), insulating films need to be applied to the six surfaces of the bare battery's metal casing to make the bare battery a coated battery, which serves the purpose of electrical isolation (insulation), as well as corrosion protection and decoration. This is known in the industry as battery coating.

[0003] The insulating film is made of polyethylene terephthalate (PET). The insulating film is generally 0.08~0.15mm thick and has excellent insulation, high temperature resistance, flame retardancy, heat dissipation and tensile rigidity. The adhesive is a polymer binder (one or more of polyvinylidene fluoride-hexafluoropropylene copolymer, polyvinylidene fluoride, polymethyl methacrylate, polyethylene oxide, polyacrylonitrile, polystyrene, polyvinyl acetate, and polyvinylpyrrolidone). The adhesive has excellent insulation, high temperature resistance, flame retardancy, heat dissipation and adhesion. The adhesive layer is generally 0.01~0.05mm thick. The adhesive will not solidify under natural conditions for a long time, but it can be accelerated by ultraviolet light (UV) irradiation.

[0004] See Figure 13 and Figure 14 Generally, insulating film is made into the form of insulating film tape 221. The back of insulating film tape 221 is coated with adhesive. The adhesive-coated side of insulating film tape 221 is adhered to release film tape 222. Then, insulating film tape 221 is stacked on the outside and release film tape 222 on the inside to form a double-layer film tape 22. The double-layer film tape 22 is then wound onto a roll 21 to form a double-layer film tape roll 20. During use, the release film tape 222 is peeled off, and the release film tape 222 is generally wound back onto the roll 21 to form a release film tape roll 30 for recycling. The release film tape 222 is made of polyethylene (PE), typically 0.05~0.1mm thick; the roll 21 is made of paper or rubber.

[0005] The existing technology uses a whole strip of insulating film 221 to wrap the battery. The steps for covering the six surfaces of the battery casing are as follows: first, take some surfaces and lay them to form the covering surface; after laying, cut the insulating film strip 221 to obtain insulating film strip segment 221A. See [link to relevant documentation]. Figure 1 The process involves applying insulating film strip 221 to the left, bottom, and right large surfaces of battery 10, making these surfaces the application surfaces. This transforms the bare battery 10 into a film-coated battery 10A. The remaining surfaces of the film-coated battery 10A are then treated as follows: Figure 1The front, rear, and top surfaces of the 10A coated battery shown are then folded together with an insulating film extending from the coating surface to form a folded surface, resulting in a coated battery. Depending on the type of coating surface, it can be categorized into a U-shaped coating or a... Figure 1 The U-shaped film shown is used to package battery films, which are divided into U-shaped films and circular films.

[0006] The principle of application is to use the relative movement of the battery 10 and the insulating film tape 20 to make them linearly contact and simultaneously roll and adhere them to form an application line, which is carried out continuously. The requirements for battery film application are: (a) During the film application process, the insulation film tension is 1.5±0.5 kgf and the film application pressure is 15±5 kgf; (ii) There is no peeling, bubbles, wrinkles, scratches, or dirt after the film is applied; (iii) The positioning accuracy of the insulating film strip edge and the battery surface after the film is applied is ±1mm.

[0007] In existing technologies, the main method of battery film application is to push the battery 10 flat towards the approximately vertically orthogonally arranged insulating film strip 221, or to push the battery 10 vertically towards the approximately horizontally orthogonally arranged insulating film strip 221. However, at the moment of contact and rolling, the distance between the positioning line and the application line of the insulating film strip 221 is referred to as the application distance (denoted as S, see [reference]). Figure 26 The distance is relatively far, which causes inaccurate positioning control of the insulating film tape 221, resulting in a low pass rate for film application accuracy.

[0008] To address this, we provide a flip-type film applicator with a short application distance that improves the positioning accuracy of the insulating film tape, thereby increasing the pass rate of film application positioning accuracy. Summary of the Invention

[0009] The purpose of this invention is to provide a square aluminum-cased battery flipping and film-applying machine, which is used to feed in and out batteries, flip the batteries, and feed in insulating film tape for film application. This improves the positioning accuracy of the insulating film tape, thereby increasing the pass rate of film application positioning accuracy.

[0010] This invention is implemented as follows: a square aluminum-cased battery flipping and film-applying machine includes: Machine tool; A battery transport and flipping device is fixed at the far right end of the machine and is used to feed in and out batteries and flip the batteries during the film application process. The film-laying device is fixed at the leftmost end of the machine base and is used to lay up the double-layer film tape roll and the release film tape roll, release the double-layer film tape, peel the double-layer film tape into the insulating film tape and the release film tape, rewind and recycle the release film tape, and release and correct the deviation of the insulating film tape. A film storage device is fixed in the middle of the machine and connected to the film dispensing device. It is used to store the insulating film tape and tension the entire insulating film tape, including the insulating film tape when applying the film. A film feeding device is fixed in the middle of the machine and located below the film storage device. It connects the film storage device and the battery transport and flipping device. It is used to provide insulating film with a short bonding distance for battery flipping and film application and to cut the insulating film strip after film application. The film-applying rolling device is fixed at the far right end of the machine and located above the battery transport and flipping device. It is used to roll the insulating film tape to apply the film to the battery.

[0011] Compared with the prior art, the beneficial effects of this invention are as follows: The battery transport and flipping device feeds and delivers batteries, and flips them during the film application process; the film-laying device holds the double-layer film tape roll and the release film tape roll, releases the double-layer film tape, peels the double-layer film tape into insulating film tape and release film tape, rewinds and recovers the release film tape, and releases and corrects the deviation of the insulating film tape; the film-storing device stores the insulating film tape and tensions the entire insulating film tape, including the insulating film tape during film application; the insulating film tape feeding device provides the insulating film with a short application distance for battery flipping and cutting the insulating film tape after film application; the film-rolling device rolls the insulating film tape to apply film to the battery; the accuracy and pass rate of battery flipping and film application are high.

The film-laying device 300 is fixed at the leftmost end of the machine base 100 and is used to lay up the double-layer film tape roll 20 and the release film tape roll 30, release the double-layer film tape 22, peel the double-layer film tape 22 into the insulating film tape 221 and the release film tape 222, rewind and recycle the release film tape 222, and release and correct the deviation of the insulating film tape 221. A film storage device 400 is fixed in the middle of the machine base 100 and connected to a film dispensing device 300. It is used to store the insulating film tape 221 and tension the entire insulating film tape 221, including the insulating film tape 221 when tensioning the film. The film feeding device 500 is fixed in the middle of the machine base 100, located below the film storage device 400, and connects to the film storage device 400 and the battery transport and flipping device 200. It is used to provide insulating film for battery flipping and film application and to cut the insulating film strip 221 after film application. The film rolling device 600 is fixed at the rightmost end of the machine base 100, located above the battery transport and flipping device 200, and is used to roll the insulating film tape 221 onto the batteries.

The battery clamping mechanism 230 is fixed on the battery transport mechanism 250 and is used to clamp the battery 10 for feeding in and feeding out the battery 10. The battery flipping mechanism 240 is fixed on the battery transport mechanism 250 and is used to clamp and flip the battery 10 for applying the film. The battery clamping mechanism 230 and the battery flipping mechanism 240 clamp the battery 10 in mutually perpendicular directions, and can clamp the two opposing surfaces of the battery 10 at the same time. When the battery clamping mechanism 230 is not clamping the battery 10, it does not prevent the battery flipping mechanism 240 from flipping the battery 10.

[0018] The battery transport and flipping device 200 loads and holds the battery 10 at the loading / unloading station 270 via the battery clamping mechanism 230. The battery transport mechanism 250 then sends the clamped battery 10 to the film application station 280 and hands it over to the battery flipping mechanism 240 for clamping. The battery flipping mechanism 240 then flips the battery 10 for film application, turning the battery 10 into a film-coated battery 10A. The battery flipping mechanism 240 then hands the film-coated battery 10A over to the battery clamping mechanism 230 for clamping. Finally, the battery transport mechanism 250 sends the clamped film-coated battery 10A out to the loading / unloading station 270 for unloading the film-coated battery 10A.

[0034] The application process of this square aluminum-cased battery flip-over film applicator is as follows: See Figure 26The battery clamping mechanism 230 of the battery transport and flipping device 200 loads and clamps the battery 10 at the loading / unloading station 270, making the battery 10 upright. The battery transport mechanism 250 sends the clamped battery 10 to the film application station 280 and hands it over to the battery flipping mechanism 240 for clamping. The battery flipping mechanism 240 flips the battery 10 to tilt it at a preset angle. At the same time, the film feeding lifting mechanism 520 of the film feeding device 500 lifts and lowers in coordination with the film feeding translation mechanism 530, and delivers the end of the insulating film tape 221 to the top edge of the upward-facing surface of the battery 10 (leaving a long section outside the top surface of the battery 10). The film application roller 680 of the film application rolling device 600 presses down onto the insulating film tape 221 on the top edge of the upward-facing surface of the battery 10 to form the initial film application line. The battery flipping mechanism 240 then... The battery 10 continues to flip. The film feeding lifting mechanism 520 descends and the film feeding translation mechanism 530 moves to the left. The rolling film-applying roller 680 continues to press down and rolls with the battery to continue applying the film. During the subsequent flipping process of the battery 10, the film feeding lifting mechanism 520 rises and falls and the film feeding translation mechanism 530 moves to continue feeding the film. The rolling film-applying roller 680 continues to rise and fall and rolls to apply the film until the battery 10 completes a 270° flip and film application. Finally, the film cutting mechanism 540 of the film feeding device 500 cuts the insulating film strip to obtain the film-applied battery 10A. The battery flipping mechanism 240 then flips the film-applied battery 10A to an upright position and hands it over to the battery clamping mechanism 230 for clamping. Finally, the battery transport mechanism 250 sends the clamped film-applied battery 10A to the unloading station 270 for unloading the film-applied battery 10A. This completes the flipping and film application of one battery.

[0035] See Figure 26 The beneficial effects of this square aluminum shell battery flipping and film-applying machine are: during the flipping and film-applying process, at the instant when the film-applying roller 680 contacts the insulating film strip 221 and simultaneously crushes it, the distance between the positioning line and the application line of the insulating film strip 221, referred to as the fixed application distance (code S), is relatively close, which can accurately control the insulating film strip 221 and achieve a high film-applying accuracy qualification rate.
