Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, specifically to a battery insulating film attaching device. Background Technology

[0002] In the battery production process, to ensure the safety and stability of the battery, it is usually necessary to attach an insulating film to the outer wall of the battery to prevent short circuits between the battery and other components. Currently, the attachment of battery insulating film mainly relies on manual operation or simple semi-automatic equipment. Manual attachment is inefficient, labor-intensive, and difficult to guarantee the attachment accuracy, which can easily lead to problems such as misaligned or wrinkled insulating film, affecting the quality and performance of the battery. Therefore, developing a battery insulating film attachment device is of great practical significance.

[0003] Referring to the novel battery side adhesive application device with announcement number CN116315131A, it can automatically apply battery side adhesive tape. It can be connected to a production line or used independently via a conveyor belt, offering high efficiency and consistent tape application, effectively improving product yield. It mainly includes a frame and a controller. The frame houses two processing tables, a robotic arm, and a side adhesive tape application mechanism. Conveyor belts are located on both sides of the processing tables, and the side adhesive tape application mechanism is symmetrically positioned on both sides of the processing tables. The side adhesive tape application mechanism includes a mounting plate I, on which a tape suction mechanism and a tape pressing mechanism are mounted. The adhesive feeding and cutting mechanism, adhesive suction mechanism, and adhesive pressing mechanism are installed inside the mounting plate I, while the adhesive feeding and cutting mechanism is installed outside the mounting plate I. The adhesive feeding and cutting mechanism includes a lead screw slide I and an adhesive side limiting plate. The slide plate of the lead screw slide I is equipped with a cutting blade driven by a cutting cylinder. This device is mainly used for battery side adhesive application. As can be seen from the above, although this device can be used well, it is usually not convenient to quickly position the battery body, which makes it easy for displacement to occur during the battery application process, thus affecting the application accuracy of the battery, which often troubles users. Utility Model Content

[0004] The purpose of this invention is to provide a battery insulating film attaching device to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to quickly position the battery body, which makes the battery attachment process prone to displacement, thus affecting the battery attachment accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery insulating film attaching device, comprising a frame, a plurality of legs on one side of the frame, a base mounted on the top of the plurality of legs, limiting rails on both sides of the top of the base, a rail block slidably connected to the top of the limiting rail, an attaching platform mounted on the top of the rail block, L-shaped limiting blocks mounted on both sides of the top of the attaching platform, a battery body mounted on the top of the attaching platform between the L-shaped limiting blocks, a second bearing seat fixedly mounted on the top of the base on one side of the attaching platform, a second telescopic cylinder mounted on the top of the second bearing seat, a U-shaped abutment block mounted on one end of the second telescopic cylinder, and the end of the U-shaped abutment block away from the second telescopic cylinder contacting the outer wall of the battery body.

[0006] Preferably, a first guide roller is rotatably mounted on one side of the support frame surface, and a second guide roller is rotatably mounted on the support frame surface below the first guide roller. The arrangement of the first guide roller and the second guide roller is used to guide and limit the insulating film strip.

[0007] Preferably, an unwinding roller is rotatably mounted on the surface of the upright on one side of the first guide roller, and a first motor is mounted on the outer wall behind the upright at the position of the unwinding roller. One end of the first motor passes through the upright and is connected to one end of the unwinding roller. The unwinding roller is driven to rotate by the first motor.

[0008] Preferably, a second motor is installed on the outer wall behind the support frame below the first motor. One end of the second motor passes through the support frame and is equipped with a take-up roller. The second motor is configured to drive the take-up roller to rotate.

[0009] Preferably, an insulating film strip is wound around the outer wall of the take-up roller. One end of the insulating film strip passes through the outer walls of the second guide roller and the first guide roller in sequence and is connected to the outer wall of the unwind roller. The insulating film strip has a plurality of insulating film sheets inside. The insulating film sheets are arranged to adhere to the outer wall of the battery body for insulation protection.

[0010] Preferably, a first support seat is fixedly installed on the surface of the upright between the unwinding roller and the winding roller. A first telescopic cylinder is installed at the top of the first support seat, and a pressure block is installed at one end of the first telescopic cylinder. The first telescopic cylinder is configured to drive the pressure block to move horizontally.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the battery insulating film attaching device not only ensures the attaching accuracy of the battery body when the attaching device is used, but also achieves the purpose of easy attaching of the battery body, and also achieves the purpose of easy disassembly and replacement of the battery body.

[0012] (1) By setting two L-shaped limiting blocks, the battery body is placed on the top of the attachment platform between the L-shaped limiting blocks. The lower end of the battery body can be limited by the L-shaped limiting blocks. Then, the U-shaped abutment block is driven to move horizontally by the second telescopic cylinder, so that the U-shaped abutment block moves horizontally and fits against the outer wall of the battery body. The battery body can be quickly positioned and placed to reduce the displacement phenomenon during the attachment process of the battery body, thereby ensuring the attachment accuracy of the battery body when the attachment device is used.

[0013] (2) By driving the unwinding roller and the winding roller to rotate synchronously by the first motor and the second motor respectively, the insulating film strip is slowly unwound, so that the insulating film sheet inside the insulating film strip is aligned with the outer wall of the battery body. Then, the pressure block is driven to move by the first telescopic cylinder so that the pressure block attaches the insulating film sheet to the outer wall of the battery body, thereby achieving the purpose of easy attachment of the battery body.

[0014] (3) By sliding the attachment platform laterally, the rail block is moved to the top of the limiting rail and the attachment platform is moved to the right away from the insulating film strip, so as to facilitate the disassembly and replacement of the battery body.
