Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, specifically a film applicator based on a servo control system. Background Technology

[0002] Film applicators are machines specifically designed for applying protective films to industries such as electronics, communications, and semiconductors. They ensure bubble-free and scratch-free film application and are automatic applicators for assembling self-adhesive parts. The equipment is stable, easy to operate, and convenient to use. Glass products, displays, and other substrate products are indispensable in people's daily lives, and these products all require film application during production. With the rapid development of mechanical automation technology, automated production is gradually replacing traditional manual production and is gradually developing towards integrated processing equipment.

[0003] When applying film to a substrate, the substrate inevitably contains some dust or other floating matter in the workshop. When these impurities fall onto the substrate, the dust will adhere between the film and the substrate, thus affecting the film application effect. Some existing film application machines are equipped with a blower to blow away the dust on the substrate surface before film application. However, due to the static electricity on the substrate surface, the blower is not effective enough in cleaning the dust on the substrate. Utility Model Content

[0004] The purpose of this invention is to provide a film application machine based on a servo control system to solve the problem that the blower mechanism is not convenient for thoroughly cleaning dust from the substrate surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a film applicator based on a servo control system, comprising a conveyor belt, a film applicator body disposed on one side above the conveyor belt, a support plate disposed on one side of the film applicator body above the conveyor belt, and further comprising:

A guide plate 43 is located on one side below the bellows 42 to facilitate the exhaust of high-pressure air from the bellows 42. Several air holes 44 are provided inside the guide plate 43 to facilitate blowing air onto the substrate surface for dust removal. Rotating shafts 45 are fixedly connected to both ends of the bellows 42. The air blowing angle between the bellows 42 and the guide plate 43 can be easily adjusted by the rotating shafts 45. One end of the rotating shaft 45 passes through the support plate 3, and a frustum 46 is fixedly connected to the outer side of the rotating shaft 45. The frustum 46 can be used to cooperate with the arc plate 47 to press and fix the rotating shaft 45. An arc-shaped plate 47 is provided above the platform 46. By setting the arc-shaped plate 47, it is easy to press and fix the platform 46 and the rotating shaft 45 together. A fastening bolt 48 is rotatably connected inside the arc-shaped plate 47. By setting the fastening bolt 48, it is easy to move the arc-shaped plate 47 downwards to press it onto the platform 46. A dust-adhesive assembly 5 is provided on the support plate 3 for adhering and absorbing dust on the surface of the substrate. The dust-adhesive assembly 5 includes a dust-adhesive roller 51 on one side of the support plate 3. By setting the dust-adhesive roller 51, it is easy to adhere and absorb firmly adhering dust on the surface of the substrate on the conveyor belt 1, improving the cleaning effect of dust and other impurities on the substrate. Pressure rollers 52 are provided on both sides of the dust-adhesive roller 51. By setting the pressure rollers 52, it is easy to... The adhesive roller 51 is pressed against the upper surface of the substrate to prevent the substrate from sticking to the adhesive roller 51 and causing positional displacement.

The through groove on the support plate 3 can facilitate the movement of the transmission shaft connected to the servo motor 56 and prevent the support plate 3 from blocking the transmission shaft of the servo motor 56.

[0030] refer to Figure 5 As shown, the bearing 53 is embedded inside the mounting assembly 8. The mounting assembly 8 includes a rectangular seat 81. By setting the rectangular seat 81, the bearing 53 can be easily supported and installed. A cover plate 82 is connected above the rectangular seat 81. By setting the cover plate 82, the bearing 53 can be easily pressed onto the bearing 53 to fix its position in the rectangular seat 81. The cover plate 82 is fixedly connected to the rectangular seat 81 by several connecting bolts 83. By setting the connecting bolts 83, the cover plate 82 can be easily fixedly connected to the rectangular seat 81. The rotating support 55 is rectangular, and the cover plate 82 and connecting bolts 83 are also set above the rotating support 55. By setting the cover plate 82 and connecting bolts 83 on the rotating support 55, the rectangular block 54 can be easily installed and removed from the rotating support 55.

[0031] refer to Figure 4 and Figure 5As shown, support blocks 9 are fixedly connected to both ends of the rectangular base 81. The support blocks 9 facilitate the fixing and support of the sliding plate 10. One side of the support block 9 is embedded inside the support plate 3 and slidably connected within the support plate 3. The sliding plate 10 is fixedly connected above the support block 9. The sliding plate 10 facilitates the up-and-down movement of the support block 9 to adjust its height. A limiting plate 11 is fixedly connected to the top of the sliding plate 10. The limiting plate 11 facilitates the connection of the sliding plate 10 to the lower pressure plate 12, preventing the sliding plate 10 from falling out of the lower pressure plate 12. The limiting plate 11 and the top of the sliding plate 10 are embedded inside the lower pressure plate 12. The lower pressure plate 12 facilitates the movement of the sliding plate 10 and the lower pressure plate 12. The support block 9 can be moved up and down to adjust the height. The lower pressure plate 12 is equipped with several pressure springs 13. By setting the pressure springs 13, it is easy to control the pressure of the sticky roller 51 pressing on the substrate, and prevent the sticky roller 51 from pressing on the substrate too much, which would cause the substrate to deform or be damaged. The bottom of the pressure spring 13 abuts against the limiting plate 11. The sliding plate 10 and the limiting plate 11 are slidably connected inside the lower pressure plate 12. The top of the lower pressure plate 12 is fixedly connected to a horizontal plate 14. By setting the horizontal plate 14, it is easy to drive the lower pressure plate 12 to move up and down to adjust the height. The upper center of the horizontal plate 14 is fixedly connected to the telescopic end of the electric push rod 15. By setting the electric push rod 15, it is easy to drive the horizontal plate 14 to move down to adjust the height.

[0032] Working principle: First, adjust the blowing angle of the air blowing hole 44. After adjusting the blowing angle of the air blowing hole 44 by rotating the guide plate 43, rotate the fastening bolt 48. The fastening bolt 48 drives the arc plate 47 to move downward and press it onto the truncated cone 46, thereby fixing the angle between the truncated cone 46, the rotating shaft 45 and the air box 42. Then, start the electric push rod 15. The electric push rod 15 drives the horizontal plate 14, the lower pressure plate 12, the sliding plate 10, the support block 9 and the rectangular seat 81 to move downward, thereby driving the dust roller 51 to move downward. When the dust roller 51 is adjusted to a height that can closely contact the upper surface of the substrate, start the conveyor belt 1 and feed the substrate onto the conveyor belt 1. When the substrate moves on the conveyor belt 1, connect the high-pressure air pipe 41. 1. High-pressure air is poured into the air box 42 and blown out through the air hole 44 onto the substrate through the guide plate 43, thereby blowing away dust from the substrate surface. When the substrate passes the sticky roller 51, the sticky roller 51 can stick tightly to the upper surface of the substrate and roll on the upper surface of the substrate. The stickiness of the sticky roller 51 itself can stick and adsorb the dust and other impurities that are firmly attached to the substrate, thereby cleaning the dust on the substrate. When it is necessary to clean or replace the sticky roller 51, the connecting bolts 83 on the cover plate 82 above the rectangular seat 81 and the rotating support 55 can be removed respectively. Then the cover plate 82 can be removed from the rectangular seat 81 and the rotating support 55 respectively, thereby releasing the fixation of the sticky roller 51, making it convenient to remove the sticky roller 51 for cleaning or replacement.
