By setting an elastic support member on one side of the battery fixing position, the film material to be applied to the battery can be in an oblique state. When the film material rolling mechanism rolls and applies the film material to the battery, it can promptly squeeze out the air between the battery and the film material, prevent the generation of air bubbles, and effectively improve the film material application effect.

The film-applying mechanism can roll along the end of the film closest to the battery towards the end of the film closest to the elastic support member, so that the film is adhered to the battery surface. This allows air between the battery and the film to be squeezed out in time during the film-applying process, preventing the formation of air bubbles and effectively improving the film-applying quality, thereby improving product quality and aesthetics. At the same time, the elastic support member can undergo elastic deformation under the rolling pressure of the film-applying mechanism, without interfering with the operation of the film-applying mechanism, which is conducive to the normal and stable operation of the film-applying device.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] refer to Figures 1 to 3 The film material oblique application device provided in this embodiment includes a rotary transfer mechanism 1, a film material feeding mechanism 2, and a film material rolling mechanism 3. The film material feeding mechanism 2 and the film material rolling mechanism 3 are sequentially arranged on the outer periphery of the rotary transfer mechanism 1 along the rotation direction of the rotary transfer mechanism 1. The rotary transfer mechanism 1 includes a turntable 11 and a first drive assembly 12 for driving the turntable 11 to rotate. A plurality of battery fixing positions 111 are equally spaced along the circumference of the turntable 11, preferably four. In some embodiments, the first drive assembly 12 may include a drive cylinder or a drive motor.

[0038] An elastic support 112 is provided on one side of the battery fixing position 111. The height of the elastic support 112 is higher than the height of the battery located on the battery fixing position 111. The elastic support 112 is used to support the film to be applied. It should be noted that a layer of double-sided adhesive is attached to the upper surface of the battery located on the battery fixing position 111. When the film to be applied is fed onto the battery by the film feeding mechanism 2, the opposite ends of the film to be applied abut against the battery and the elastic support respectively. The film to be applied is placed at an angle on the battery. Then, the battery and the film to be applied move with the turntable 11 to the position of the film rolling mechanism 3. The film rolling mechanism 3 rolls the film from the end of the film closest to the battery toward the end of the film closest to the elastic support 112, so that the film is tightly attached to the battery surface. Since the film is rolled at an angle, the film rolling mechanism 3 can squeeze out the air between the battery and the film in time during the rolling process, effectively preventing the generation of air bubbles, thereby improving the adhesion effect of the film and improving product quality and aesthetics.

[0039] Because the elastic support 112 has a certain elasticity, it can support the film material in its natural state. However, under the rolling pressure of the film material rolling mechanism 3, it can undergo elastic deformation and release its supporting effect on the film material, thereby avoiding interference with the rolling operation of the film material rolling mechanism 3 and ensuring the normal and stable operation of the film material oblique bonding device. It should be noted that when the film material rolling mechanism 3 completes the rolling of the film material and resets, the elastic support 112 will spring back and reset, lifting the corner of the film material again. Since the film material is already firmly bonded to the battery surface at this time, the supporting force of the elastic support 112 is much less than the adhesion force between the film material and the battery. The elastic support 112 will only lift the part of the film material that is not bonded to the battery at the corner, and will not cause the film material to detach from the battery. Therefore, it will not affect the bonding effect between the film material and the battery.

[0040] In one embodiment, two elastic supports 112 are located on the side of the battery fixing position 111 near the outer periphery of the turntable 11. Each elastic support 112 supports two corner positions on one side of the film to be applied. Each elastic support 112 includes a support spring 1121 and a support block 1122. The bottom end of the support spring 1121 is connected to the turntable 11, and the top end of the support spring 1121 is connected to the support block 1122. The support block 1122 is cylindrical, and its top has a planar structure, allowing for more stable contact with the film application mechanism 3.

[0041] In some embodiments, a first suction member 113 is provided on the battery fixing position 111, the first suction member 113 being used to adsorb and fix the battery. The first suction member 113 may include suction cups or suction holes; in this embodiment, the first suction member 113 includes multiple suction cups.

[0042] The film-adhesive device of this embodiment uses an elastic support member on one side of the battery fixing position to make the film to be applied to the battery tilted. When the film-adhesive rolling mechanism rolls and applies the film to the battery, it can squeeze out the air between the battery and the film in time, prevent the generation of air bubbles, and effectively improve the film-adhesive effect, thereby improving the quality and aesthetics of the battery product.

[0043] Example 2

[0044] As a further optimization of Example 1, refer to Figures 4 to 8 The film material feeding mechanism 2 includes a film material fixing component 21 and a second driving component 22 that is motive-connected to the film material fixing component 21. In this embodiment, the second driving component 22 is a robotic arm.

[0045] The film material fixing assembly 21 includes a first mounting plate 211, a second adsorption member 212, and a connector 213. The second adsorption member 212 is provided with several suction holes for adsorbing and fixing the film material. The first mounting plate 211 is mounted horizontally on the driving end of the second driving assembly 22. The first mounting plate 211 has a first end 2111 and a second end 2112 at opposite ends. The second adsorption member 212 has a third end 2121 and a fourth end 2122 at opposite ends. The first end 2111 is connected to the third end 2121, and the second end 2112 is connected to the fourth end 2122 through the connector 213. As a result, the second adsorption member 212 is inclined relative to the first mounting plate 211, so that the film material adsorbed and fixed by the second adsorption member 212 is also inclined, ensuring that the film material to be attached is applied to the battery in an inclined state. This structural arrangement of the film material fixing assembly 21 helps to improve the fit between the film material feeding mechanism 2 and the elastic support member 112, thereby improving production efficiency and quality.

[0046] The film application mechanism 3 includes a roller assembly 31, a third drive assembly 32 for driving the roller assembly 31 to move vertically, and a fourth drive assembly 33 for driving the roller assembly 31 and the third drive assembly 32 to move horizontally. In this embodiment, both the third drive assembly 32 and the fourth drive assembly 33 include drive motors. During the application process, the third drive assembly 32 first drives the roller assembly 31 to descend vertically and press against the film and the battery. Then, driven by the fourth drive assembly 33, it moves horizontally along the end of the film near the battery to the end of the film near the elastic support member 112, so that the film adheres tightly to the battery surface. After the application process is completed, the roller assembly 31 will reset under the drive of the third drive assembly 32 and the fourth drive assembly 33, waiting for the next application process.

[0047] In some embodiments, a silicone layer may be provided on the surface of the roller assembly 31 at the location where it contacts the film material to reduce friction between the roller assembly 31 and the film material, thereby protecting the film material.

[0048] In some embodiments, the film rolling mechanism 3 further includes a transmission assembly 34 for resetting the shaft of the roller assembly 31. The transmission assembly 34 includes a guide rail 341 arranged vertically, a second mounting plate 342 slidably connected to the guide rail 341, a rack 343 arranged horizontally on the second mounting plate 342, and a gear set 344 connected between the rack 343 and the shaft of the roller assembly 31. The rack 343 is arranged in a direction parallel to the driving direction of the fourth drive assembly 33.

[0049] Understandably, when the third drive assembly 32 drives the roller assembly 31 to descend, the rack 343 and gear set 344 will move downwards along with the roller assembly 31 under the guidance of the guide rail 341. When the fourth drive assembly 33 drives the roller assembly 31 to move horizontally, the rack 343 remains in the same position, while the gear set 344 rolls horizontally along the surface of the rack 343, causing the shaft of the roller assembly 31 to rotate. When the fourth drive assembly 33 drives the roller assembly 31 to reset, the gear set 344 rolls horizontally in the opposite direction along the rack 343, causing the shaft of the roller assembly 31 to reset. Through the driving action of the fourth drive assembly 33, both the overall position movement and reset of the roller assembly 31 and the rotation and reset of the roller assembly 31's shaft can be achieved. Through the transmission action of the transmission assembly 34, the number of drive assemblies is reduced, thus lowering the cost.

[0050] In this embodiment, a pressure sensor 35 is provided on the roller assembly 31, which can be used to sense and control the pressure between the roller assembly 31 and the battery, thereby avoiding damage to the battery due to excessive pressure during the rolling process and further improving the quality of production operations.

[0052] As a further optimization of Example 2, refer to Figures 9 to 10 The film material oblique bonding device also includes a feeding mechanism 4. The film material feeding mechanism 2, the film material rolling mechanism 3, and the feeding mechanism 4 are sequentially arranged on the outer periphery of the rotary transfer mechanism 1 along the rotation direction of the rotary transfer mechanism 1. Under the rotation of the turntable 11, each battery fixing position 111 can sequentially pass through the film material feeding station, the film material rolling station, and the feeding station.

[0053] In one embodiment, the unloading mechanism 4 includes a battery fixing assembly 41, a fifth drive assembly 42 for driving the battery fixing assembly 41 to rotate, and a sixth drive assembly 43 for driving the battery fixing assembly 41 and the fifth drive assembly 42 to move vertically. Under the drive of the fifth drive assembly 42, the unloaded battery can be flipped so that the loading mechanism in the next process can remove the battery from the battery fixing assembly 41.

[0054] In this embodiment, both the fifth drive component 42 and the sixth drive component 43 can be drive cylinders or drive motors, and the battery fixing component 41 can include battery clamps or battery adsorption components, etc.
