Description

Technical Field

[0001] This utility model relates to the field of automatic adhesive applicators, and more particularly to an automatic adhesive applicator for battery pack protective films. Background Technology

[0002] Mica sheets are used as protective films in automotive battery packs primarily because they possess several key properties that provide comprehensive protection for the battery pack. Mica sheets have excellent insulation properties, effectively isolating current and preventing current leakage within the battery pack. This avoids safety hazards such as short circuits and fires caused by leakage, ensuring the electrical safety of the battery pack.

[0003] When applying mica sheets to car battery packs, automatic adhesive applicators typically apply adhesive to the mica sheets before attaching them to the battery pack. The automatic adhesive applicator can use a spraying method to apply the adhesive to the mica sheets. This spraying method ensures that the adhesive forms a uniform layer on the surface of the mica sheets, preventing the adhesive from being too thick or too thin, thus improving the bonding effect.

[0004] In existing technologies, when applying adhesive-coated mica sheets to battery packs, they are typically placed one above the other for better adhesion. However, this method lacks buffering and limiting functions when the mica sheet approaches the battery pack, causing the battery pack to shift at the moment the mica sheet gets close. Furthermore, the mica sheet may collide with the battery pack due to excessive or rapid impact during movement, reducing the accuracy and stability of the adhesion. Therefore, an automatic adhesive applicator for battery pack protective films is proposed to address these issues. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an automatic adhesive applicator for battery pack protective films, which aims to improve the problem that existing automatic adhesive applicators for battery pack protective films lack buffering and limiting protection for mica plates and battery packs, resulting in reduced bonding efficiency and bonding stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic adhesive applicator for battery pack protective film, comprising a machine body, a bracket fixedly connected to the side wall of the machine body, a conveyor belt provided on the surface of the bracket, a receiving box fixedly connected to the outer wall of the machine body, an adhesive application bin fixedly connected to the top of the machine body, a support frame fixedly connected to the top of the machine body, a motor fixedly connected to the top of the support frame, a rotating frame fixedly connected to the output end of the motor via a rotating shaft, a cylinder fixedly connected to the top of the rotating frame, a fixed frame fixedly connected to the output end of the cylinder, a vacuum pump fixedly connected to the inner wall of the fixed frame, a connecting plate fixedly connected to the bottom of the fixed frame, a vacuum suction cup fixedly connected to the bottom of the connecting plate, a limit component provided on the top of the machine body, and a buffer component provided on the top of the machine body.

[0008] The output end of the vacuum pump is fixedly connected to the top of the vacuum suction cup via a series hose.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a support base, an electric push rod is fixedly connected to the inner surface of the support base, and a clamping plate is fixedly connected to the output end of the electric push rod.

[0011] As a further description of the above technical solution:

[0012] The bottom end of the support base is fixedly connected to the top of the machine body, and the clamping plate is located on the top of the conveyor belt.

[0013] As a further description of the above technical solution:

[0014] The buffer assembly includes a fixed cylinder with a rectangular hole at the top. A buffer rod is slidably connected to the inner wall of the rectangular hole. A return spring is fixedly connected to the surface of the buffer rod. An airbag is fixedly connected to the inner wall of the fixed cylinder. A telescopic spring is fixedly connected to the inner wall of the airbag. A contact plate is fixedly connected to the outer wall of the connecting plate.

[0015] As a further description of the above technical solution:

[0016] The bottom end of the fixed cylinder is fixedly connected to the top of the clamping plate, and the top end of the reset spring is fixedly connected to the top of the inner wall of the fixed cylinder.

[0017] As a further description of the above technical solution:

[0018] A trapezoidal block is fixedly connected to the inner wall of the fixed cylinder, a trapezoidal block is fixedly connected to the outer wall of the buffer rod, a magnetic sheet is fixedly connected to the top of the airbag, and a magnetic sheet is fixedly connected to the bottom of the buffer rod.

[0019] As a further description of the above technical solution:

[0020] The bottom of trapezoidal block one is inclined upwards, and the top of trapezoidal block two is inclined downwards.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a vacuum pump and a vacuum suction cup are used to achieve negative pressure to adsorb the mica after it has been coated with adhesive. A motor and a cylinder can drive the coated mica plate from the coating chamber to the battery pack on the conveyor belt. The limiting component can provide a fixed limit for the battery pack, and the buffer component can provide a certain resistance buffer when the mica plate and the battery pack are bonded. This ensures the bonding efficiency between the battery pack and the protective film, while avoiding the risk of displacement caused by impact due to excessive bonding speed or large bonding speed, and improving bonding accuracy.

[0023] 2. In this utility model, the mutual repulsion between magnetic sheet one and magnetic sheet two, combined with the fact that the downward resistance between trapezoidal block one and trapezoidal block two is greater than the upward resistance, further improves the buffering efficiency of the buffer assembly, while also improving the reset efficiency of the buffer component, thus ensuring the buffering effect.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an automatic battery pack protective film applicator, comprising a machine body 1, a support 2 fixedly connected to the side wall of the machine body 1, a conveyor belt 3 disposed on the surface of the support 2, and drive rollers disposed at both ends of the conveyor belt 3, one set of drive rollers being driven by a drive motor. The conveyor belt 3 is used to transport battery packs. A receiving box 4 is fixedly connected to the outer wall of the machine body 1, the interior of the receiving box 4 being used to place mica sheets, and a lifting mechanism disposed at the bottom of the receiving box 4, the lifting mechanism being driven by a drive motor to drive a lead screw. The machine consists of a screw that rotates to lift a lifting plate inside a receiving box 4. The lifting plate holds stacked mica sheets. The receiving box 4 has an opening on the side near the glue application tank 5. A hydraulic cylinder pushes the top mica sheet out through the opening into the glue application tank 5. The glue application tank 5 is fixedly connected to the top of the machine body 1. Several sets of equidistant nozzles are located at the bottom of the glue application tank 5.

When the glue spraying machine is started, the nozzle will evenly spray glue onto the surface of the mica board. The center of the conveyor belt 3 is at a 90-degree angle to the glue application bin 5, and its rotation amplitude is equal to that of the rotating frame 8. A support frame 6 is fixedly connected to the top of the machine body 1, and a motor 7 is fixedly connected to the top of the support frame 6. The output end of the motor 7 is fixedly connected to the rotating frame 8 via a rotating shaft. A cylinder 9 is fixedly connected to the top of the rotating frame 8, and a fixed frame 10 is fixedly connected to the output end of the cylinder 9. The fixed frame 10 contains... A vacuum pump 11 is fixedly connected to the wall. A connecting plate 12 is fixedly connected to the bottom of the fixed frame 10. A vacuum suction cup 13 is fixedly connected to the bottom of the connecting plate 12. The output end of the vacuum pump 11 is fixedly connected to the top of the vacuum suction cup 13 through a series hose. Several sets of vacuum suction cups 13 are provided and connected to the vacuum pump 11 through a series hose provided in the inner cavity of the connecting plate 12. Multiple sets of vacuum suction cups 13 can ensure the stability of adsorption on the mica plate. A limit component is provided on the top of the machine body 1, and a buffer component is provided on the top of the machine body 1.

[0033] Reference Figure 3 - Figure 5The limiting assembly includes a support base 14, the bottom end of which is fixedly connected to the top of the machine body 1. An electric push rod 15 is fixedly connected to the inner surface of the support base 14. A clamping plate 16 is fixedly connected to the output end of the electric push rod 15. The clamping plate 16 is located at the top of the conveyor belt 3. Two sets of limiting assemblies are provided and are mirror-shaped with the central axis of the conveyor belt 3 as the axis of symmetry. The two sets of clamping plates 16 can fix and clamp the battery pack by driving the electric push rod 15. The buffer assembly includes a fixing cylinder 18, the bottom end of which is fixedly connected to the top of the clamping plate 16. A rectangular hole 20 is opened at the top of the fixing cylinder 18, and the inner wall of the rectangular hole 20 is... A buffer rod 19 is slidably connected. The buffer rod 19 is made of a set of discs and a set of rectangular rods. The sliding of the rectangular rods and the rectangular holes 20 can prevent the buffer rod 19 from rotating inside the fixed cylinder 18. A return spring 23 is fixedly connected to the surface of the buffer rod 19. The top of the return spring 23 is fixedly connected to the top of the inner wall of the fixed cylinder 18. An air bladder 21 is fixedly connected to the inner wall of the fixed cylinder 18. The top of the air bladder 21 is provided with an opening to allow air to enter. A telescopic spring 22 is fixedly connected to the inner wall of the air bladder 21. A contact plate 17 is fixedly connected to the outer wall of the connecting plate 12. The contact plate 17 can contact the top of the buffer rod 19 when the connecting plate 12 descends.

[0034] Reference Figure 5 A trapezoidal block 26 is fixedly connected to the inner wall of the fixed cylinder 18. The bottom of the trapezoidal block 26 is inclined upward. A trapezoidal block 27 is fixedly connected to the outer wall of the buffer rod 19. The top of the trapezoidal block 27 is inclined downward. A magnetic sheet 24 is fixedly connected to the top of the airbag 21. The center of the magnetic sheet 24 is open to avoid obstructing the air inlet of the airbag 21. A magnetic sheet 25 is fixedly connected to the bottom of the buffer rod 19. The sides of the magnetic sheet 24 and the magnetic sheet 25 that are close to each other have mutual repulsive magnetic force, which allows the buffer rod 19 to move upward quickly after it descends.

[0035] Working principle: After the mica plate is sprayed with glue through the glue application tank 5, the motor 7 starts and drives the rotating frame 8 to rotate into the glue application tank 5. The cylinder 9 drives the fixed frame 10 to descend until the vacuum suction cup 13 is in contact with the surface of the mica plate. The vacuum pump 11 starts, creating a negative pressure between the vacuum suction cup 13 and the mica plate to adsorb it. At the same time, the cylinder 9 drives the fixed frame 10 to rise, and the motor 7 reverses to drive the rotating frame 8 to reset. At this time, the conveyor belt transports the first battery pack to the designated position and then stops. The two sets of electric push rods 15 open at the same time, driving the two sets of clamping plates 16 to move closer to each other. The two sets of clamping plates 16 fix and limit the two sides of the battery pack. The cylinder 9 descends again, causing the adsorbed mica plate to gradually approach the top of the battery pack. At this time, the contact plate 17 contacts the buffer rod 19 first. The buffer rod 19 slides downward inside the fixed cylinder 18 under force. The return spring 23 is randomly activated. When stretched, magnetic sheet 24 and magnetic sheet 25 form a repulsive force, and trapezoidal block 26 and trapezoidal block 27 come into contact. Due to the inclined surfaces of the two, the resistance of the buffer rod 19 in descending is greater than the resistance in ascending. When the buffer rod 19 continues to descend, it will compress the airbag 21, so the telescopic spring 22 will be compressed. When the mica plate comes into contact with the battery pack, it is connected to the battery pack by the glue sprayed on the mica plate. Then, the vacuum pump 11 releases the mica plate by the vacuum suction cup 13, and the cylinder 9 randomly drives the fixed frame 10 to rise, completing the work of coating the battery pack with a protective film. During the bonding process, a certain downward resistance is provided to the mica plate. The resistance can have a certain buffering and positioning effect, so that the mica plate can be more accurately bonded to the predetermined position, avoiding deviation or misalignment caused by excessive speed or force, and ensuring the bonding accuracy.
