Description

Technical Field

[0001] The invention relates to the technical field of battery packaging, and in particular to an automatic film pasting device for four sides of a battery. Background Art

[0002] The main purpose of the film around the battery is to ensure the safety of the battery during transportation, storage and use through insulation protection. The film usually uses a single-sided sticky insulating material (such as PET blue film), which can effectively prevent scratches on the battery surface, leakage and electrolyte contamination. In addition, the film can also play a role in waterproofing and dustproofing, reducing the impact of the external environment on battery performance, and at the same time meet the requirements for creepage distance during battery cell assembly (that is, the conductor edge spacing must match the voltage level to avoid insulation failure due to excessive voltage). This process can also avoid potential risks such as deformation of the battery shell and abnormal opening of the explosion-proof valve, ensure the integrity of the appearance and clear QR code identification, and provide convenience for subsequent inspection and maintenance.

[0003] Battery film operations are generally carried out manually or semi-manually, usually requiring the single-sided sticky insulating film to be stretched manually and adhered to the battery surface, covering the bottom and sides in a U-shaped or four-sided wrapping manner, and using rollers or guide ramps to complete the folding process to avoid wrinkles. Finally, the excess film layer is cut off and the appearance integrity and insulation performance are checked. This method is prone to uneven film lamination, bubbles or wrinkles during operation, and has low production efficiency and poor consistency, making it difficult to meet the needs of large-scale production. Summary of the invention

[0004] The main purpose of the present invention is to provide an automatic film laminating device for the four sides of a battery. The linear drive device can drive the battery to move through a displacement component, and use the movement of the battery to drive the film to move, so that the film is located on three sides of the battery, and the first pushing component and the second pushing component can fit the initial free end of the film and the free end after cutting on the remaining side of the battery to achieve film laminating operations around the battery without manual participation, thereby improving efficiency.

[0011] Furthermore, a rotating cylinder is fixed on the L-shaped plate, and the rotating end of the rotating cylinder is connected to two rotating rods, and the distance between the two rotating rods is greater than the width of the battery.

[0012] Furthermore, it also includes a material unwinding component for unwinding the film roll.

[0013] Furthermore, the discharge assembly includes a supporting plate, a servo motor is installed on the top of the supporting plate, the output shaft on the top of the servo motor passes through the supporting plate and is connected to a turntable, a positioning shaft is fixed at the center position of the top of the turntable, and a first shaft and a second shaft are also arranged on the top of the supporting plate.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1-7 As shown, an automatic film-sticking device for four sides of a battery comprises a first plate body 1 and a second plate body 2 arranged opposite to each other, the first plate body 1 and the second plate body 2 are located at the same height, guide grooves 10 are provided on the first plate body 1 and the second plate body 2, the guide grooves 10 of the first plate body 1 and the second plate body 2 match, so that the battery can be moved from the first plate body 1 to the second plate body 2 through the guide grooves 10, a first pushing component 7 and a second pushing component 8 are fixed on both sides of the second plate body 2, a fitting component 9 for attaching the film to the side wall of the battery is arranged on the first pushing component 7 and the second pushing component 8, and also comprises a pulling component 3 for pulling the film, a linear driving device 13 is arranged above the first plate body 1 and the second plate body 2, and a displacement component 6 for driving the battery to move is arranged at the driving end of the linear driving device 13.

[0031] In this embodiment, a feeding assembly 5 for unwinding the film roll is also included. The feeding assembly 5 can unwind the film roll, and the pulling assembly 3 can pull the free end of the film roll, so that the unwound film can be located on the path where the battery moves. When 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 shown in FIG. Figure 3 As shown, during this process, the battery will contact the unfolded film, and as the battery moves, the film can cover the three sides of the battery, and the length of the film on the opposite sides of the battery is greater than the length of the battery. In this state, the first pushing component 7 works, and the pulling component 3 no longer clamps the film, so that the first pushing component 7 fits the free end of the film to the remaining end of the battery. In the second step, as shown in FIG. Fig. 9 As shown, the pulling component 3 returns to the discharge component 5 again, and the pulling component 3 clamps the middle part of the unfolded film again. At this time, the second pushing component 8 cuts off the film between the battery and the pulling component 3, and fits the free end of the cut film to the side of the battery to complete the battery coating operation, and then the pulling component 3 pulls the clamped free end of the film back to the side of the first pushing component 7 to wait for subsequent coating operations.

[0032] Among them, 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, and 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 body 1 and the second plate body 2, and the clamping cylinder 303 is located in the gap 11, therefore, the first cylinder 302 can drive the clamping cylinder 303 to do lifting operations, so that the clamping cylinder 303 and the clamping plate 304 pass through the bottom of the first plate body 1 when pulling the film in the second step, and then rise and reset to realize the pulling operation of the film.

[0033] Among them, Figure 1 , Figure 3 and Figure 4 As shown, the first pushing assembly 7 and the second pushing assembly 8 are arranged opposite to each other, and are both located at the top of the first plate body 1 and close to the gap 11. The first pushing assembly 7 and the second pushing assembly 8 both include a third cylinder 801, and 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, so that the push plate 802 is used to adhere the film to the side of the battery, and the push plate 802 of the second pushing assembly 8 is equipped with a cutter 12. Therefore, when the push plate 802 of the second pushing assembly 8 moves, it can cut the film so that the cut film is adhered to the side of the battery.

[0034] Among them, Figure 3 and Figure 4 As shown, the laminating component 9 includes a fixing plate 901 fixed to one side of the push plate 802, and at least two groups of positioning rods 902 are slidably inserted on the fixing plate 901. A pressing plate 904 is fixed to one end of the positioning rod 902, and a spring 903 is provided and connected between the pressing plate 904 and the fixing plate 901. Under normal conditions, the spring 903 is in an initial state, and in the process of the push plate 802 moving to laminate the film onto the battery, the pressing plate 904 will contact the side of the battery. As the push plate 802 continues to move, the spring 903 will be forced to retract, thereby enabling the pressing plate 904 to continue to move while laminating one side of the battery. When the push plate 802 is reset, the pressing plate 904 is also reset under the action of the spring 903. The battery is located in the guide groove 10 and is limited by the guide groove 10 , so when the pressing plate 904 pushes the battery, the battery will not move laterally.

[0035] like Figure 5 As shown, the displacement assembly 6 includes a fourth cylinder 602 fixed on the driving 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, and then when the linear drive device 13 drives the displacement assembly 6 to move, the battery will also move.

[0036] A rotating cylinder 605 is fixed on the L-shaped plate 603, and the rotating end of the rotating cylinder 605 is connected to two rotating rods 606. The distance between the two rotating rods 606 is greater than the width of the battery. Under normal circumstances, the two rotating rods 606 are in a horizontal state. When the L-shaped plate 603 drives the battery to move, Figure 8 As shown, the rotating cylinder 605 will drive the 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 respectively. Therefore, during the movement of the battery, the rotating rod 606 will contact the film, so that the film will not contact the battery during the movement of the battery. Furthermore, during the movement of the battery, the film can continue to be transmitted under force, ensuring that the length of the film transmission meets the requirements of the battery coating.

[0037] Among them, Figure 7 As shown, the discharge component 5 includes a carrier plate 505, a servo motor 504 is installed on the top of the carrier plate 505, the output shaft on the top of the servo motor 504 passes through the carrier plate 505 and is connected to a turntable 506, a positioning shaft 503 is fixed at the center position of the top of the turntable 506, and a first shaft 501 and a second shaft 502 are also provided on the top of the carrier plate 505. The film roll is sleeved on the positioning shaft 503, so that it is located on the top of the turntable 506, and its free end is limited by the second shaft 502 and the first shaft 501, and is finally pulled and clamped by the pulling component 3, so that the film is unfolded to 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 rotating shaft to rotate, thereby further unfolding the film, so that the unfolded length of the film follows the displacement length of the battery, so as to ensure that after the battery stops displacing, the unfolded film length can cover all around the battery.

[0038] like Figure 1As shown, a baffle 14 is installed on one side of the top of the first plate body 1, and a pushing mechanism 4 is installed on the side of the top of the first plate body 1 opposite to the baffle 14. The pushing mechanism 4 includes a fifth cylinder 401, and a pushing plate 402 is fixed to an output shaft on one side of the fifth cylinder 401. The baffle 14 is located on one side of the guide groove 10. When the battery is placed in the guide groove 10 on the first plate body 1, the fifth cylinder 401 drives the pushing plate 402 to move, so that the pushing plate 402 contacts the battery. After the battery is subjected to force, a certain displacement will occur, so that one side of the battery contacts the baffle 14. The baffle 14 is used as a positioning reference to ensure that the initial position of the battery meets the requirements.

[0039] Working principle, first, the film roll is placed on the positioning shaft 503 so that it is located on the top of the turntable 506, and its free end is limited by the second shaft 502 and the first shaft 501, and finally pulled and clamped by the pulling component 3, so that the film is unfolded to the top of the gap 11, and next, the linear drive 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, and then when the linear drive device 13 drives the displacement component 6 to move, the battery will also move, and when the L-shaped plate 603 drives the battery to move, the rotating cylinder 605 will drive the 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 respectively. 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, and then the film can continue to be transmitted during the movement of the battery, ensuring that the length of the film transmission meets the requirements of the battery coating, so that the film is located on three sides of the battery. In the next step, when the battery moves to the second plate 2, the first pushing component 7 works, and the pulling component 3 no longer clamps the film, so that the first pushing component 7 presses the free end of the film on the remaining side of the battery, and then the pulling component 3 returns to the discharge component 5 again, and the pulling component 3 clamps the middle part of the unfolded film again. At this time, the second pushing component 8 cuts off the film between the battery and the pulling component 3, and fits the free end of the cut film to the side of the battery to complete the battery coating operation, and then the pulling component 3 clamps the free end of the film and returns to one side of the first pushing component 7, waiting for subsequent coating operations.
