Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery packaging, in particular to a four-side automatic film pasting device for storage battery. BACKGROUND

[0002] The main purpose of the film wrapping around the four sides of the storage battery is to ensure the safety of the battery during transportation, storage and use through insulation protection. The film wrapping usually uses single-sided adhesive insulating material (such as PET blue film), which can effectively prevent the battery surface from being scratched, leaking and electrolyte pollution. In addition, the film wrapping can also play a role in waterproofing and dustproofing, reducing the influence of the external environment on the performance of the battery, while meeting the requirements of the creepage distance during the assembly of the battery cell (i.e. the edge distance of the conductor needs to match the voltage level to avoid insulation failure due to excessive voltage), which can also avoid potential risks such as deformation of the battery shell and abnormal opening of the explosion-proof valve, ensuring the integrity of the appearance and the clarity of the two-dimensional code identification, and providing convenience for subsequent detection and maintenance.

[0003] The film operation of the storage battery is usually achieved manually or semi-manually. The single-sided adhesive insulating film is usually manually stretched and pasted on the surface of the battery. The bottom and side are covered by U-shaped or four-side wrapping, and the edge folding is completed by means of rollers or guide slopes to avoid wrinkles. Finally, the excess film layer is cut and the appearance integrity and insulation performance are checked. This method is prone to uneven film pasting, air bubbles or wrinkles during operation, and has low production efficiency and poor consistency, which is difficult to meet the needs of large-scale production.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1-7 As shown, an automated film-applying device for four sides of a storage battery includes a first plate 1 and a second plate 2 arranged opposite to each other at the same height. Guide grooves 10 are formed on the first plate 1 and the second plate 2, and the guide grooves 10 of the first plate 1 and the second plate 2 are matched so that the battery can be moved from the first plate 1 to the second plate 2 through the guide grooves 10. A first pushing assembly 7 and a second pushing assembly 8 are fixed on both sides of the second plate 2. The first pushing assembly 7 and the second pushing assembly 8 are provided with an adhesion assembly 9 for attaching the film to the side wall of the battery. The device also includes a pulling assembly 3 for pulling the film. A linear drive device 13 is provided above the first plate 1 and the second plate 2. The driving end of the linear drive device 13 is provided with a displacement assembly 6 for moving the battery.

[0033] In this embodiment, a feeding assembly 5 for unfolding the film roll is also included. The feeding assembly 5 can unfold the film roll, and the pulling assembly 3 can pull the free end of the film roll, so that the unfolded film can be located on the path of battery movement. After the battery is placed in the guide groove 10 on the first plate 1, the linear drive device 13 can drive the displacement assembly 6 to move, so that the battery moves on the second plate 2. In the first step, as Figure 3 As shown, during this process, the battery comes into contact with the unfolded film, and as the battery moves, the film covers three sides of the battery, with the length of the film on opposite sides of the battery being greater than the length of the battery. In this state, the first pushing component 7 operates, and the pulling component 3 no longer holds the film, thereby causing the first pushing component 7 to attach the free end of the film to the remaining end of the battery. The second step, as...Figure 9 As shown, the pulling component 3 returns to the feeding component 5 and clamps the middle part of the unfolded film again. At this time, the second pushing component 8 cuts the film between the battery and the pulling component 3 and attaches the free end of the cut film to the side of the battery to complete the battery coating operation. Then the pulling component 3 pulls the free end of the clamped film back to one side of the first pushing component 7, waiting for the subsequent coating operation.

[0034] Among them, such as Figure 1 As shown, the pulling assembly 3 includes a first cylinder 302 and a second cylinder 301. A clamping cylinder 303 is fixed on the output shaft of the first cylinder 302. Clamping plates 304 for clamping the film are fixed on the two clamping ends of the clamping cylinder 303. The output shaft of the second cylinder 301 is connected to the first cylinder 302 to drive the first cylinder 302 to move horizontally. A gap 11 is left between the first plate 1 and the second plate 2. The clamping cylinder 303 is located in the gap 11. Therefore, the first cylinder 302 can drive the clamping cylinder 303 to perform lifting and lowering operations, so that the clamping cylinder 303 and the clamping plate 304 pass through the bottom of the first plate 1 during the second step of pulling the film, and then rise and reset to realize the film pulling operation.

[0035] Among them, such as Figure 1 , Figure 3 and Figure 4 As shown, the first pushing component 7 and the second pushing component 8 are arranged opposite to each other, both located on the top of the first plate 1 and near the gap 11. Both the first pushing component 7 and the second pushing component 8 include a third cylinder 801. A push plate 802 is fixed on the output shaft of the third cylinder 801. The third cylinder 801 can drive the push plate 802 to move, thereby using the push plate 802 to adhere the film to the side of the battery. A cutter 12 is installed on the push plate 802 of the second pushing component 8. Therefore, when the push plate 802 of the second pushing component 8 moves, it can cut the film, so that the cut film adheres to the side of the battery.

[0036] Among them, such as Figure 3 and Figure 4 As shown, the bonding assembly 9 includes a fixing plate 901 fixed to one side of the push plate 802. At least two sets of positioning rods 902 are slidably inserted on the fixing plate 901. A pressure plate 904 is fixed to one end of each positioning rod 902. A spring 903 is connected between the pressure plate 904 and the fixing plate 901. Normally, the spring 903 is in its initial state. During the process of the push plate 802 moving to bond the film to the battery, the pressure plate 904 will contact the side of the battery. As the push plate 802 continues to move, the spring 903 will be forced back, thus allowing the push plate 802 to continue moving while the pressure plate 904 is bonded to the side of the battery. When the push plate 802 returns to its original position, the pressure plate 904 also returns to its original position under the action of the spring 903.

[0037] The battery is located in the guide groove 10 and is limited by the guide groove 10. Therefore, the battery will not move laterally when the pressure plate 904 pushes the battery.

[0038] like Figure 5 As shown, the displacement component 6 includes a fourth cylinder 602 fixed to the drive end of the linear drive device 13. The linear drive device 13 is a linear motor. The bottom output shaft of the fourth cylinder 602 is connected to an L-shaped plate 603. The fourth cylinder 602 can drive the L-shaped plate 603 to descend, so that the vertical part of the L-shaped plate 603 contacts the end of the battery. Thus, when the linear drive device 13 drives the displacement component 6 to move, the battery will also move.

[0039] The L-shaped plate 603 is equipped with a rotating cylinder 605. Two rotating rods 606 are connected to the rotating end of the cylinder 605. The distance between the two rotating rods 606 is greater than the width of the battery. Normally, the two rotating rods 606 are horizontal. However, when the L-shaped plate 603 moves the battery, such as… Figure 8 As shown, rotating cylinder 605 will drive two rotating rods 606 to rotate and become vertical. At this time, the two rotating rods 606 will be located on both sides of the battery end. Therefore, during the battery movement, the rotating rods 606 will contact the film, so that the film will not contact the battery during the battery movement. In this way, the force on the film can continue to be transmitted during the battery movement, ensuring that the length of film transmission meets the battery coating requirements.

[0040] Among them, such as Figure 7 As shown, the feeding assembly 5 includes a support plate 505, a servo motor 504 is mounted on the top of the support plate 505, and the output shaft of the servo motor 504 passes through the support plate 505 and is connected to a turntable 506. A positioning shaft 503 is fixed at the center of the top of the turntable 506. The top of the support plate 505 is also provided with a first shaft 501 and a second shaft 502. The film roll is sleeved on the positioning shaft 503 and thus located on the top of the turntable 506. Its free end is limited by the second shaft 502 and the first shaft 501 and is finally pulled and clamped by the pulling assembly 3, so that the film unfolds above the gap 11. When the battery moves in the guide groove 10, the end of the battery will contact the unfolded film. As the battery continues to move, the servo motor 504 will drive the turntable 506 and the shaft to rotate, thereby further unfolding the film, so that the length of the unfolded film follows the length of the battery displacement, so as to ensure that after the battery stops moving, the length of the unfolded film can cover the battery.

[0041] like Figure 1As shown, the first plate body 1 top side is provided with a baffle 14, the first plate body 1 top side opposite the baffle 14 is provided with a pushing mechanism 4, the pushing mechanism 4 comprises a fifth cylinder 401, the fifth cylinder 401 side output shaft is fixed with a push plate 402, the baffle 14 is located on one side of the guide groove 10, when the battery is put into the guide groove 10 on the first plate body 1, the fifth cylinder 401 drives the push plate 402 to move, so that the push plate 402 contacts the battery, the battery will displace after being forced, so that one side contacts the baffle 14, taking the baffle 14 as a positioning reference, to ensure that the initial position of the battery meets the requirements.

[0042] The working principle is that firstly, the film roll is sleeved on the positioning shaft 503, and the free end of the film roll is limited through the second shaft body 502 and the first shaft body 501, and finally the film is pulled and clamped through the pulling assembly 3, so that the film is unfolded above the gap 11. Next, the linear driving device 13 works to drive the L-shaped plate 603 to move to one side of the battery. At this time, the fourth cylinder 602 drives the L-shaped plate 603 to descend, so that the vertical part of the L-shaped plate 603 contacts the end of the battery. When the linear driving device 13 drives the displacement assembly 6 to move, the battery will also move. When the L-shaped plate 603 drives the battery to move, the rotating cylinder 605 will drive the two rotating rods 606 to rotate to the vertical state. At this time, the two rotating rods 606 will be located on both sides of the battery. Therefore, during the movement of the battery, the rotating rod 606 will contact the film, so that the film does not contact the battery during the movement of the battery. Thus, during the movement of the battery, the film can continue to be transmitted, ensuring that the length of the film transmission meets the needs of the battery film covering, so that the film is located at three sides of the battery. Next, when the battery moves to the second plate body 2, the first pushing assembly 7 works, and the pulling assembly 3 no longer clamps the film, so that the first pushing assembly 7 presses the free end of the film on the remaining side of the battery. Then the pulling assembly 3 returns to the feeding assembly 5 again, and the pulling assembly 3 clamps the middle part of the unfolded film again. At this time, the second pushing assembly 8 cuts off the film between the battery and the pulling assembly 3, and the free end of the cut film is attached to the side of the battery, to complete the film covering work of the battery. Then the free end of the film clamped by the pulling assembly 3 returns to one side of the first pushing assembly 7, waiting for subsequent film covering work.

[0043] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
