Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, and specifically to a spraying equipment for thin film production. Background Technology

[0002] A film is a thin and flexible transparent sheet, usually made of plastic and rubber or other materials. Films can be used in a variety of fields, such as machinery, electronics, or printing. During film production, the film surface needs to be coated according to the film production standards. Film coating is a common surface treatment technology. By spraying liquid materials onto the film surface, the appearance, function, and performance of the film can be changed. In film coating, choosing the right coating and coating process is crucial.

[0003] Patent application number CN202323191091.5 belongs to the field of semiconductor manufacturing technology, specifically a thin film spraying setup, including a spraying device body; a second slider is slidably connected to the top of the spraying device body, and a spraying machine is fixedly connected to the end of the second slider; a placement plate is fixedly connected to the middle of the spraying device body; two support frames are fixedly connected to the top of both sides of the spraying device body, the two support frames are arranged opposite each other, a first connecting rod is fixedly connected to the middle of the two support frames, and a second connecting rod is fixedly connected to the end of the first connecting rod; a fan can increase the curing speed of the thin film after spraying, and the direction can be adjusted to make the curing of the thin film more uniform. The direction can be flexibly adjusted to the required direction, increasing the curing time of the thin film can enhance the stability of the film, making the film more durable during processing and use, reducing shrinkage during the film spraying process, and increasing the quality of the film.

[0004] However, the patent does not explain that when a thicker coating is sprayed onto the surface of the film, the curing speed of the coating decreases. If the film is then blown by a fan, the coating will flow, resulting in uneven film thickness and affecting the performance.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a spraying equipment for thin film production that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: including: a machine body, an unwinding roller for winding film, and a take-up roller;

[0008] Along the direction of film movement, the following components are arranged in sequence: a spraying mechanism for spraying liquid, a heating mechanism for accelerating the curing of the coating liquid, a drying box fixedly installed on the machine body, and a camera;

[0009] The heating mechanism includes: a fixed rod fixedly installed on the machine body, a limiting sleeve fixedly installed on the fixed rod, a heating roller slidably installed on the limiting sleeve, a spring fixedly installed between the heating roller and the limiting sleeve, and a nut threadedly connected to the heating roller;

[0010] The two ends of the spring are fixedly connected to the heating roller and the limiting sleeve, respectively.

[0011] Furthermore, a hot air duct and an air outlet assembly for discharging hot air from the hot air duct are fixedly installed inside the drying oven;

[0012] The hot air duct is connected to a hot air blower.

[0013] Furthermore, a connecting plate is fixedly installed on the hot air duct, a connecting shaft is rotatably installed on the connecting plate, and a rotating shaft is fixedly installed on the connecting shaft.

[0014] Furthermore, the air outlet assembly includes: an air guide plate fixedly installed on the fixed shaft, an elastic connector fixedly installed on the air guide plate, an abutment plate, and a second spring.

[0015] Furthermore, the spraying mechanism includes: a spray head fixedly mounted on the machine body and a positioning roller rotatably mounted on the machine body.

[0016] Furthermore, a transmission rod is fixedly installed on the heating roller, and an abutment rod is fixedly installed on the transmission rod.

[0017] Furthermore, a limiting groove is provided on the hot air duct, a limiting plate is slidably connected to the limiting groove, and the limiting plate is fixedly connected to the transmission rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a spraying equipment for thin film production. When the thickness of the thin film coating is large, the position of the heating roller is moved upward, which simultaneously drives the transmission rod and the abutment rod to move upward. At this time, the abutment rod pushes the air guide plate to rotate through the fixed shaft and the rotating shaft. The abutment plates on the two sets of air guide plates push the other two sets of air guide plates to move synchronously. At the same time, the springs are deformed, so that the air guide port formed by the four sets of air guide plates is larger and the outlet area is larger. The wind force blowing towards the thin film coating is smaller, which avoids blowing the thin film coating apart, resulting in uneven film surface thickness and more comprehensive curing effect. It has a better curing effect for thin film coatings of different thicknesses. In addition, the heating roller preheats the thin film coating, further ensuring that the thin film coating will not be blown apart by hot air, which would affect the processing effect of the film.

[0028] 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. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0030] like Figures 1 to 7 As shown, the present invention provides a film production spraying equipment comprising: a machine body 1, an unwinding roller 2 for winding film, and a take-up roller 3; the unwinding roller 2 and the take-up roller 3 are respectively installed at both ends of the machine body 1 and are driven to rotate by a motor, thereby realizing the unwinding and take-up of the film, and spraying the film surface during the unwinding and take-up process to improve the film's performance.

[0031] Specifically, along the direction of film movement, there are in sequence: a spraying mechanism 4 for spraying liquid, a heating mechanism 5 for accelerating the curing of the coating liquid, and a drying box 6 fixedly installed on the machine body 1. After the film is released by the unwinding roller 2, it is sprayed with a coating by the spraying mechanism 4, and then the coating is cured by the heating mechanism 5 and the drying box 6. The film is then detected by the camera 7 to identify whether there is any uneven spraying. Finally, it is retracted by the take-up roller 3 to complete the film spraying work. It should be noted that the camera 7 is installed on the machine body 1 to take pictures of the film from above, and a supplementary light is provided on the opposite side of the camera 7 to improve the detection effect of the camera 7 on the film and improve the detection accuracy.

[0032] The spraying mechanism 4 includes: a spray head 41 fixedly installed on the machine body 1, and a positioning roller 42 rotatably installed on the machine body 1. When the film moves, it first passes through the positioning roller 42 to be pressed, and then passes through the spray head 41 for spraying, so as to avoid the film moving during spraying and affecting the spraying effect.

[0033] The heating mechanism 5 includes: a fixed rod 51 fixedly installed on the machine body 1; a limiting sleeve 52 fixedly installed on the fixed rod 51; the limiting sleeve 52 can limit the position of the heating roller 53 during adjustment to prevent the heating roller 53 from shaking and reducing the adjustment accuracy; the heating roller 53 is slidably installed on the limiting sleeve 52; a spring 54 is fixedly installed between the heating roller 53 and the limiting sleeve 52; and a nut 55 is threadedly connected to the heating roller 53. The heating roller 53 passes through the fixed rod 51 and is threadedly connected to the nut 55. After the position of the heating roller 53 is adjusted, it is fixed by the nut 55. The two ends of the spring 54 are fixedly connected to the heating roller 53 and the limiting sleeve 52 respectively. When the heating roller 53 is adjusted, it will drive the spring 54 to deform. When it is necessary to restore the heating roller 53 to the default position, the nut 55 is rotated to disengage from the heating roller 53. At this time, the spring 54 resets and drives the heating roller 53 to reset.

[0034] Before use, the heating roller 53 is pushed to adjust its position under the limit of the limiting sleeve 52 according to the thickness of the coating on the film. After adjustment, it is fixed with nut 55. It should be noted that the heating roller 53 needs to maintain a thickness of at least 2.5 cm with the film to avoid the film from being damaged due to excessive temperature of the heating roller 53. In addition, in order to more accurately ensure the moving distance of the heating roller 53, it can also be pushed by a cylinder or electric telescopic rod. This application adopts manual adjustment.

[0035] A hot air duct 61 is fixedly installed inside the drying oven 6, and an air outlet assembly 62 is installed to discharge the hot air inside the hot air duct 61; the hot air duct 61 is connected to a hot air blower.

[0036] The hot air blower blows hot air into the hot air pipe 61 and discharges it through the air outlet assembly 62 to further cure the thin film coating, thereby increasing the curing speed of the thin film coating. In other words, this application uses the drying oven 6 and the heating mechanism 5 to perform dual curing of the thin film coating, which greatly improves the curing effect of the thin film coating.

[0037] In addition, it should be explained in detail that, depending on the thickness and flowability of the thin film coating, this application can use the drying oven 6 and the heating mechanism 5 separately. Specifically, when the thickness of the thin film coating is relatively thin, either the drying oven 6 or the heating mechanism 5 can be used for heating and curing. When the thickness of the thin film coating is relatively thick, both the drying oven 6 and the heating mechanism 5 can be used for heating and curing. The advantage of doing so is that the thin film coating is first heated by the heating mechanism 5 to achieve preliminary curing, avoiding the thin film coating from flowing due to direct air blowing curing, which would affect the flatness of the film. Then, the drying oven 6 is used for large-area and faster curing to ensure the curing effect of the thin film coating, resulting in better performance.

[0038] To supplement the above, a connecting plate 63 is fixedly installed on the hot air duct 61, a connecting shaft 631 is rotatably installed on the connecting plate 63, and a rotating shaft 632 is fixedly installed on the connecting shaft 631. The air outlet assembly 62 includes: an air guide plate 621 fixedly installed on the fixed shaft, an elastic connector 622, an abutment plate 623, and a spring 624 fixedly installed on the air guide plate 621. A transmission rod 626 and a transmission rod 627 are fixedly installed on the heating roller 53. A connecting rod 625 is fixedly installed on the 6, and the connecting rod 625 abuts against the air guide plate 621; the air guide plate 621 is arranged in a ring around the hot air pipe 61 as the axis, with four sets of elastic connectors 622 fixedly installed on two adjacent sets of air guide plates 621, and the connecting plate 623 fixedly installed on two opposite sets of air guide plates 621, and two sets of connecting plates 623 are installed on each set of air guide plates 621. Spring 624 is fixedly installed on the other two opposite sets of air guide plates 621.

[0039] When the film coating thickness is large, the position of the heating roller 53 is moved upward, which simultaneously drives the transmission rod 626 and the abutment rod 625 to move upward. At this time, the abutment rod 625 pushes the air guide plate 621 to rotate through the fixed shaft and the rotating shaft 632. The abutment plates 623 on the two sets of air guide plates 621 push the other two sets of air guide plates 621 to move synchronously, while the second spring 624 deforms, making the air guide opening size formed by the four sets of air guide plates 621 larger. When the air guide plate 621 rotates, the elastic connector 622 deforms adaptively to avoid the gaps between the air guide plates 621 from affecting the hot air discharge. The elastic connector 622 can be made of rubber. The second spring 624 is used to drive the two sets of air guide plates 621 to reset their positions for easy subsequent use.

[0040] In other words, when the film coating is thicker, the temperature of the heating roller 53 needs to be increased, and the heating roller 53 needs to be pulled upward so that the heating roller 53 can heat and cure the film coating over a larger area, while avoiding damage to the film. When the heating roller 53 is adjusted, it simultaneously drives the four sets of air guide plates 621 to rotate, so that the hot air outlet area is larger and the wind force blowing towards the film coating is smaller, avoiding blowing the film coating away, resulting in uneven film surface thickness, and more comprehensive curing effect. It has a good curing effect for film coatings of different thicknesses.

[0041] It should be added that a limiting groove 611 is provided on the hot air duct 61, a limiting plate 612 is slidably connected to the limiting groove 611, and the limiting plate 612 is fixedly connected to the transmission rod 626. When the transmission rod 626 moves, it drives the limiting plate 612 to slide on the limiting groove 611. On the one hand, it can limit the movement of the transmission rod 626, and on the other hand, it can prevent the hot air in the hot air duct 61 from moving out of the gap between the transmission rod 626 and the hot air duct 61, thus avoiding resource waste.

[0042] Working principle:

[0043] Before use, the heating roller 53 is adjusted according to the thickness of the coating on the film, and the position is fixed under the limit of the limiting sleeve 52. After the adjustment is completed, the nut 55 is used to fix it. When the position of the heating roller 53 moves upward, it drives the transmission rod 626 and the abutment rod 625 to move upward. At this time, the abutment rod 625 pushes the air guide plate 621 to rotate through the fixed shaft and the rotating shaft 632. The abutment plates 623 on the two sets of air guide plates 621 push the other two sets of air guide plates 621 to move synchronously. At the same time, the spring 624 deforms, making the air guide opening formed by the four sets of air guide plates 621 larger. Then the motor is started to drive the take-up roller 3 and the unwind roller 2 to rotate. After the film is released by the unwind roller 2, it is sprayed with a coating by the spraying mechanism 4. Then the coating is cured by the heating mechanism 5 and the drying box 6. Then the film is detected by the camera 7 to identify whether there is uneven spraying. Finally, it is retracted by the take-up roller 3 to complete the spraying of the film.
