Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling, and in particular to a battery peeling device for recycling new energy vehicle batteries. Background Art

[0002] After long-term use, the lifespan and performance of the batteries of new energy vehicles will decline. For the replaced new energy vehicle batteries, they generally need to be recycled. Among them, the batteries need to be peeled. The existing peeling method is as follows: The cylindrical 18650 battery is placed on the conveyor line, and the film on the surface of the cylindrical battery is cut by a laser to form a cross-shaped incision. Then, through multiple clamping jaws, the extrusion and kneading of the skin film are realized in sequence, and the film outside the battery core is rotated so that the film is disconnected from the incision and separated from the battery surface. Finally, the battery film is pulled out from both ends of the battery core by two flexible clamping jaws. When separating the plastic film, multiple clamping jaws need to be operated in sequence, which requires high performance and control of the clamping jaws. Excessive clamping force is likely to damage the battery core. Therefore, a battery peeling device for recycling new energy vehicle batteries is proposed to facilitate the separation of the outer film of the battery and the battery core. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that when multiple clamping jaws are used to peel the battery in sequence, the performance and control requirements for the clamping jaws are relatively high, and it is easy to cause damage to the battery core.

[0022] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the detailed implementation manners and the accompanying drawings.

[0023] The terms used in the present invention are those general terms that are currently widely used in the art in consideration of the functions of the present invention. However, these terms may change according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0024] Referring to Figures 1 to 5 , this embodiment provides a battery peeling device for recycling new energy vehicle batteries, including a support mechanism 1, which includes a fixed frame 11 and a support ring 12 provided on the fixed frame 11, and a support arm 13 is provided on the support ring 12; a loading mechanism 2, which includes a rotating frame 21 rotatably provided outside the support ring 12 and an accommodating groove 211 provided on the rotating frame 21, a limit-loop buckle 22 is provided outside the rotating frame 21, and a gear disk 23 is also provided on the rotating frame 21; a plurality of accommodating grooves 211 are provided on the rotating frame 21 in a circumferential distribution, and a semi-circular groove is provided at the position of the limit-loop buckle 22 corresponding to the accommodating groove 211 to facilitate the accommodation of the battery.

[0025] The driving mechanism 3 includes a driving motor 31 provided on the support arm 13 and an output pulley 32 provided on the driving motor 31. A pinion gear 33 is provided on the output pulley 32. The operation of the driving motor 31 can drive the output pulley 32 to rotate. The pinion gear 33 meshes with the gear disc 23. When the output pulley 32 rotates, it can drive the gear disc 23 to rotate through the pinion gear 33, thereby causing the loading mechanism 2 for placing the battery to rotate and realizing the movement of the battery position.

[0026] A fixed pulley 131 is provided on the support arm 13. The output shaft of the driving motor 31 penetrates through the fixed pulley 131, and the fixed pulley 131 is fixedly connected to the support arm 13.

[0027] It further includes a movable rubber belt 4 provided outside the output pulley 32 and a fixed rubber belt 5 provided outside the fixed pulley 131. The movable rubber belt 4 is sleeved outside the output pulley 32 and also outside the rotating frame 21. The movable rubber belt 4 has a certain elasticity. The fixed rubber belt 5 is sleeved outside the fixed pulley 131 and also outside the rotating frame 21. The fixed pulley 131 has a certain elasticity. The movable rubber belt 4 and the fixed rubber belt 5 are respectively sleeved on both ends of the rotating frame 21 and separated by the limit ring buckle 22.

[0028] During use, the battery after laser film cutting is placed in the receiving groove 211. The rotation of the driving motor 31 causes the pinion gear 33 to rotate. The rotation of the pinion gear 33 will cause the rotating frame 21 to rotate, changing the position of the battery to sequentially place the batteries in the receiving groove 211.

[0029] The fixed rubber belt 5 and the movable rubber belt 4 are attached to the surface of the battery. The fixed rubber belt 5 and the movable rubber belt 4 have a certain elasticity. Since the battery protrudes from the surface of the rotating frame 21 after being placed in the receiving groove 211, after the rotating frame 21 rotates a certain angle, the battery contacts the fixed rubber belt 5 and the movable rubber belt 4, causing the fixed rubber belt 5 and the movable rubber belt 4 to stretch. As the number of batteries increases, the tension of the fixed rubber belt 5 and the movable rubber belt 4 will also gradually increase. Therefore, when the number of batteries is small, it is convenient for the fixed rubber belt 5 and the movable rubber belt 4 to slip between the surface of the rotating frame 21, which is convenient for adding batteries at the beginning of the device operation. After the number of batteries increases, the fixed rubber belt 5 and the movable rubber belt 4 are tightened. At this time, the battery core can reduce the friction of the fixed rubber belt 5 and the movable rubber belt 4 by rolling in the receiving groove 211 to ensure the normal operation of the device.

[0030] Among them, due to the action of the output pulley 32, when the driving motor 31 operates, the moving direction of the movable rubber belt 4 is opposite to that of the rotating frame 21. Coupled with the contact between the fixed rubber belt 5 and the battery surface, the battery is positioned. Since the film on the battery surface contacts the fixed rubber belt 5 and the movable rubber belt 4, the films at both ends will be subjected to different rotational forces, which can rub and displace the film on the battery surface, causing the film on the battery surface to break at the laser film-cutting position and resulting in a slip displacement between the battery film and the battery core, making it easier to remove the battery film subsequently. Moreover, this peeling method can well protect the battery core, and at the same time, it can easily separate the battery film from the battery core, and the equipment control difficulty is significantly reduced, with a simple structure, being safe and reliable.

[0031] Preferably, one end of the support ring 12 is provided with an outer ring 121, and one end of the support ring 12 is provided with an inner ring 122; the settings of the outer ring 121 and the inner ring 122 facilitate the rotation of the rotating frame 21, limit the rotating frame 21, and at the same time can prevent the battery core from falling out of the accommodation groove 211.

[0032] An access groove 123 and an ejection groove 124 are provided on the inner ring 122. The setting of the access groove 123 can facilitate the addition of batteries to the loading mechanism 2, and the setting of the ejection groove 124 facilitates the ejection of the batteries after the battery film is rubbed and separated.

[0033] Preferably, a feeding channel 14 corresponding to the access groove 123 is provided on the inner ring 122; a top-out cylinder 15 is provided on the support ring 12, the top-out cylinder 15 corresponds to the ejection groove 124, and the top-out cylinder 15 is connected to the support ring 12 through a connecting frame 151.

[0034] Furthermore, an insertion groove 231 is provided on the gear disk 23, and the insertion groove 231 corresponds to the accommodation groove 211.

[0035] Among them, an open ring buckle 125 is provided on the outer ring 121, and a limiting post 126 is provided on the open ring buckle 125; the open ring buckle 125 is arranged corresponding to the ejection groove 124.

[0036] It should be noted that a separation mechanism 6 is further included. The separation mechanism 6 includes a guiding cover 61 provided on the support ring 12, a left separator 62 and a right separator 63 provided in the guiding cover 61, and a top-out member 64 provided in the guiding cover 61.

[0037] Among them, the left separator 62 includes a left fixing ring 621 provided in the guiding cover 61 and left rubber claws 622 provided on the left fixing ring 621. A plurality of left rubber claws 622 are arranged in a circular shape, and the plurality of left rubber claws 622 are arranged in a tapered converging shape.

[0038] Further, the right separator 63 includes a right fixing ring 631 disposed within the guiding cover 61, and a plurality of right rubber claws 632 disposed on the right fixing ring 631. The plurality of right rubber claws 632 are arranged in a circumferential and conical converging shape.

[0039] Furthermore, the ejecting member 64 includes a limiting sleeve 641 disposed within the guiding cover 61, and a ejecting rod 642 slidably disposed within the limiting sleeve 641. A spring 643 is sleeved on the outer wall of the ejecting rod 642. One end of the ejecting rod 642 is provided with a pushing end 644. The elastic force of the spring 643 enables the ejecting rod 642 to have a tendency to slide towards the right separator 63.

[0040] A blowing cover 65 is provided on the guiding cover 61.

[0041] During use, the battery is added through the feeding channel 14. The driving motor 31 controls the intermittent rotation of the rotating frame 21 to sequentially add batteries into the receiving grooves 211. During the rotation of the rotating frame 21, the surface of the battery is rubbed by the movable rubber belt 4 and the fixed rubber belt 5, causing the battery film to break and separate along the laser cut, and detach from the battery core until the battery rotates to align with the opening ring buckle 125. At this time, the battery can be ejected by the ejecting cylinder 15. The battery slides along the limiting post 126. The opening setting of the opening ring buckle 125 facilitates the dropping of the battery film during the sliding of the battery. After the film on the surface of the battery core is separated into two parts, when the battery passes through the left separator 62, the left rubber claws 622 deform and adhere to the surface of the battery core. The left rubber claws 622 grasp the film at the left end of the battery and separate it from the battery core. It should be noted that a magnetic block is provided at the output end of the ejecting cylinder 15, which can make the ejection of the battery core more stable.

[0042] As the ejection distance increases, after the battery core penetrates through the left rubber claws 622, it will be inserted into the right rubber claws 632. The right rubber claws 632 deform, and the right rubber claws 632 grasp the film at the right end of the battery film. Subsequently, the telescopic end of the ejecting cylinder 15 retracts. The end of the battery core abuts against the left rubber claws 622 and cannot retract, causing the battery core to fall, completing the entire peeling process. The blowing cover 65 is connected to a gas source. By blowing out air, the separated film and battery core can be guided to different positions for classification. When the battery is inserted into the right separator 63, the ejecting rod 642 will be resisted and slide within the limiting sleeve 641, compressing the spring 643. When the battery core is withdrawn from the right separator 63, the pushing end 644 can eject the film stuck in the right rubber claws 632, and cooperate with the air flow to make it fall. The film stuck in the left rubber claws 622 will be squeezed off when the next battery is ejected. It can separate the film and is not likely to cause the accumulation and blockage of the film.

[0043] Finally, it should be noted that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
