Description

Technical Field

[0001] The present invention belongs to the technical field of film coating equipment for square-shell batteries, and in particular relates to an L-glue pasting device for square-shell batteries. Background Art

[0002] Prismatic battery (hereinafter referred to as battery), please see Figure 1 With the liquid injection port facing forward and the top surface upward, the battery is divided into six external surfaces: top surface 11, bottom surface (not shown), left large surface 12, right large surface (not shown), front side surface (not shown), and rear side surface 13. On the center line of the top surface 11 (the exposed surface of the top cover) of a conventional battery, from front to back, are distributed the positive electrode 14, liquid injection port 15, explosion-proof window 16, QR code 17, and negative electrode 18. During the battery manufacturing process, insulating film (sheet) is applied to the six external surfaces of the bare battery aluminum shell to provide electrical isolation, corrosion protection, and decorative effects.

[0003] Typically, insulating film is manufactured as a double-layer film, with the adhesive side of the insulating film adhered to a release film of equal width. The film is then cut into sheets and stacked together for delivery, or rolled onto a roll with the insulating film on the outside and the release film on the inside. Before wrapping, the double-layer film roll is released and the release film is peeled off. The insulating film tape is then applied to the bare cell surface. During the wrapping process, the film is cut into sections and then wrapped onto the six surfaces of the bare square cell. The insulating film (sheet) is made of polyethylene terephthalate (PET), with a thickness of 0.08 to 0.15 mm and a thickness of 0.15 to 0.5 mm. It 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 polyvinyl pyrrolidone), with a thickness of 0.01 to 0.05 mm. It solidifies faster when exposed to ultraviolet light (UV), and has excellent insulation, high temperature resistance, flame retardancy, heat dissipation, and adhesion.

[0004] L-shaped adhesive is a short piece of insulating film tape that is attached to the L-shaped corner of the top surface of the battery (mostly refers to the edge of the top surface and the side surface). Figure 1 The L-type adhesive 19 in the tape should be equal to the length of the corner. Its width on both sides (mostly the top and side surfaces) at the corner should be equal and exceed 4mm (minimum creepage distance), but less than the minimum flat width of the top edge, typically 5-6mm wide. Apply the L-type adhesive before film wrapping. This is used when only half of the battery side needs to be wrapped with insulation film, saving film. The insulation film strip must be cut into small sections before or during application.

[0005] Battery sticker L glue requirements:

[0006] (1) The length is equal to the length of the corners, and the effective width is ≥ 4mm;

[0007] (2) Film sticking accuracy ±1mm;

[0008] (3) There is no delamination, bubbles, wrinkles, warping, scratches or dirt. Summary of the Invention

[0009] The purpose of the present invention is to provide a square shell battery L glue sticking device, which sticks L glue before wrapping, and is used in the case where the battery side only needs to be half-wrapped instead of fully wrapped with insulating film to save insulating film.

[0010] The present invention is implemented as follows: a square shell battery L-glue pasting device includes a battery feeding pull belt, a displacement connection device, two cleaning devices, two L-glue pasting battery feeding pull belts, two L-glue pasting devices, an L-glue pasting battery transfer device, two L-glue detection devices and two L-glue pasting NG pull belts.

Two L-glue sticking mechanisms arranged before and after the L-glue sticking station are used to feed, stick and cut glue for batteries; an L-glue sticking battery transferring device is connected to the two L-glue sticking devices, and is arranged horizontally and parallelly at right angles to the battery conveying direction, for receiving batteries with L-glue stuck, and for testing and conveying the tested L-glue sticking batteries out after testing; two L-glue detection devices are arranged parallelly along the battery conveying direction, located above the L-glue sticking battery transferring device, for respectively detecting whether the L-glue stuck on the batteries with L-glue stuck on the L-glue sticking battery transferring mechanism is qualified; two L-glue sticking NG pull belts are connected to the two ends of the L-glue sticking battery transferring mechanism, and are arranged parallelly along the battery conveying direction, for respectively receiving and temporarily storing batteries with L-glue stuck that are judged to be unqualified after testing.

[0013] In this solution, the batteries are fed into the position-shifting connecting device by the battery feeding pull belt, and the position-shifting connecting device changes the position of the batteries so that the batteries enter two different cleaning devices for battery cleaning. The cleaned batteries are respectively fed into the two L-glue pasting devices by the L-glue pasting battery feeding pull belt for L-glue pasting.

After the detection, the L-glue pasting battery transferring device further transports the unqualified batteries to the L-glue pasting NG pull belt and / or transports the qualified batteries to the coating equipment for further coating.

[0044] Compared with the prior art, multiple batteries are input into the position-shifting connecting device 300 by the battery feeding pull belt 200. The position-shifting connecting device 300 changes the position of the batteries and the relative position relationship between the batteries so that the batteries enter two different cleaning devices 400 for simultaneous battery cleaning. The cleaned batteries are respectively fed into two L-glue pasting devices 600 by two L-glue pasting battery feeding pull belts for L-glue pasting.

After the detection, the L-glue pasting battery transferring device 700 further transports the unqualified batteries to the L-glue pasting NG pull belt 900 and / or transports the qualified batteries to the coating equipment for further coating.

The displacement input area is used to connect with an external feed pull belt to input batteries, and the two displacement output areas are used to connect with two external discharge pull belts to output batteries. A displacement blocking mechanism 330 is arranged behind a displacement input area and aligned with an external feed pull belt to block the incoming batteries and stop them in the displacement input area.

The multiple shift feeding rollers are rotatably mounted horizontally between the two sides of the shift feeding bracket 311 and are connected to the movable end of the shift feeding drive 312 through the shift feeding transmission system 313. Multiple shift feeding material sensors 315 are fixed on the top of both sides of the feeding bracket, facing the shift input area or the shift output area, and are used to sense the position of the battery.

[0050] Furthermore, the shift feeding drive member 312 is a motor, which drives the shift feeding transmission system 313 to rotate, and the shift feeding roller 314 rotates under the drive of the shift feeding transmission system 313, thereby driving the battery on the shift feeding roller 314 to move back and forth.

The axes of the multiple feed rollers 3262 align with the axes of the multiple feed rollers 314 of the displacement feeding mechanism 310. The rack bracket 3261 is provided with multiple slots 32611, allowing the rack bracket 3261 to pass through the multiple feed rollers 314. Rollers are installed on the inner sides of the roller guardrail pair 3263 to provide support and position restraint for the batteries, preventing them from tipping over during ascent, descent, or horizontal movement. A horizontal displacement sensor 3264 senses and controls the translation of the rack bracket 3261 to the displacement input zone, aligned with the external feed belt, and to the displacement output zone, aligned with the external discharge belt.

[0057] In this embodiment, please refer to Figure 4 The position shifting and lifting module 324 includes a position shifting and lifting driver 3241 and a position shifting and lifting slide 3242.

The position-shifting translational transmission system 3232 can achieve different translational speeds at the two output ends, thereby increasing or decreasing the distance between the two output ends to achieve variable pitch. The two material racks 326 are fixed to the corresponding two position-shifting translational slides 3233.

[0061] Feeding: When four batteries are transported by four feeding channels of a feeding belt and slide into the shift feeding mechanism 310, the shift feeding sensor 315 of the shift feeding mechanism 310 detects the batteries and starts the shift feeding driver 312 to drive all the multiple shift feeding rollers 314 to feed the four batteries. The proximity sensor 337 of the shift stopping mechanism 330 detects the batteries and controls the stop of the shift feeding driver 312. The shift stopping driver 332 is controlled to drive the shift stopping plate 335 with the shift stopping palm 336 to extend against the batteries, so that the batteries stop in the shift input area formed by the normal lines of the multiple shift feeding rollers 314.

[0062] Lifting: Control and activate the shifting and lifting driving components 3241 of the shifting and lifting modules 324 of the two shifting mechanisms 320, driving the respective shifting frames 322 to carry the material frame 326 together with the multiple material frame rollers 3262 to rise between the multiple shifting and feeding rollers 314, so that the top surfaces of the multiple material frame rollers 3262 are higher than the top surfaces of the multiple shifting and feeding rollers 314, causing the multiple material frame rollers 3262 to lift and carry the batteries from the multiple shifting and feeding rollers 314, so that the four batteries are transferred from the shifting input area of the shifting and feeding mechanism 310 to the four shifting channels 3265 of the shifting mechanism 320.

The horizontal displacement sensor 3264 knows and controls the position of the displacement channels 3265 to align with the external feed channels;

[0064] Lowering: Control and activate the shifting and lifting driving components 3241 of the shifting and lifting modules 324 of the two shifting mechanisms 320, driving the respective shifting frames 322 to lower the material frame 326 together with the multiple material frame rollers 3262 between the multiple shifting and feeding rollers 314, so that the top surface of the multiple material frame rollers 3262 is lower than the top surface of the multiple shifting and feeding rollers 314, and the batteries are returned to the multiple shifting and feeding rollers 314 for carrying, so that the four batteries are transferred from the four shifting channels 3265 of the shifting mechanism 320 to the shifting output area of the shifting and feeding mechanism 310. The lifting displacement sensing piece 325 detects and controls the lowering position of the material frame 326;

[0065] Discharging: Control and start the variable position feeding drive 312 to drive all the multiple variable position feeding rollers 314 to output four batteries to two cleaning devices.

[0066] Reset: Control and activate the shifting and translation driving members 3231 of the shifting and translation modules 323 of the two shifting mechanisms 320, driving the respective shifting racks 322 and the empty material racks 326 to shift and change distance to the right and left respectively to the shifting input area, so that the two shifting channels 3265 thereof are aligned with the four feeding channels of an external feeding pull belt. The horizontal displacement sensing piece 3264 detects and controls the position of the shifting channels 3265 aligned with the external feeding channels;
