Description

Technical Field

[0001] This utility model relates to the field of injection molding production processing technology, and in particular to a double-sided film application device for a detector handle display. Background Technology

[0002] During the production and processing of detector handle displays, it is necessary to apply a protective film to the lens. Currently, the traditional methods for applying the protective film to injection-molded products of this type are: one is to peel the protective film directly off the substrate and apply it manually to the lens; the other is to use a simple positioning fixture to first position the protective film in the fixture, and then directly attach the product to the positioning fixture for film application.

[0003] However, the two methods of applying the film mentioned above are prone to problems such as air bubbles and fingerprints on the surface of the lens. This method of applying the film and the quality after application do not meet customers' high expectations for the appearance of the product, nor do they meet the demands of high-speed social development for high-quality development of consumer products.

[0004] Therefore, those skilled in the art have provided a double-sided film application device for a detector handle display to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a double-sided film application device for a detector handle display. This device uses vacuum adsorption to ensure a smooth and even application of the protective film, preventing wrinkles and bubbles. It also utilizes a contour positioning frame to precisely define the product position, preventing misalignment. Furthermore, the layered protective film design allows for direct application after removing the top layer, avoiding contact with dirt by fingers. The combination of these three features improves the accuracy, efficiency, and appearance quality of the film application, while saving labor and rework costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-sided film application device for a detector handle display includes a bottom frame, a cover plate, an upper protective film, and a lower protective film. A fixing plate is fixedly connected to the upper end of the cover plate. A vacuum mechanism is provided inside the bottom frame. The vacuum mechanism includes a vacuum generator and a positioning base. An air inlet pipe is fixedly connected to the air inlet of the vacuum generator. The middle part of the upper end of the fixing plate is fixedly connected to the positioning base. Multiple vacuum suction holes are opened at the upper end of the positioning base. An exhaust pipe is connected to the outer wall tank at the front end of the positioning base. The lower end of the exhaust pipe passes through the cover plate and is fixedly connected to the vacuum port of the vacuum generator. A positioning mechanism is provided at the upper end of the fixing plate. The positioning mechanism includes a positioning frame and four movable cylinders. The upper and lower protective films are both located within the positioning frame and are fixedly connected to each other by adhesive. Each of the upper and lower protective films has a separate protruding tear-off position. Guide rods are fixedly connected to the four corners of the upper end of the fixing plate.

[0008] The above technical solution addresses the issue of misalignment in traditional manual film application, which can lead to assembly interference and inefficiency due to repeated corrections after application. It utilizes vacuum adsorption technology to ensure complete adhesion between the protective film and the positioning surface, resulting in a smooth, wrinkle-free, and bubble-free application. This eliminates the need for subsequent bubble removal, saving manpower. Furthermore, the double-layer protective film design prevents hand contact with the lower layer, avoiding dirt buildup from gloves or finger cots and ensuring the product's mirror surface meets the required high aesthetic standards.

[0009] Furthermore, the upper end of the bottom frame is fixedly connected to the cover plate by multiple screws, and the vacuum generator is installed inside the bottom frame and fixed by bolts;

[0010] The above technical solution uses multiple screws to fix the bottom frame and the cover plate together, which allows for a stable installation while also enabling the two to be separated, facilitating subsequent maintenance and repair of the vacuum generator inside the bottom frame.

[0011] Furthermore, the front end of the air intake connecting pipe extends through the bottom frame to the outside of the bottom frame, and two working position air valve switches are provided in the middle of the outer wall of the front end of the bottom frame.

[0012] The above technical solution allows the air inlet pipe to pass through the bottom frame, making it convenient for workers to connect the air inlet pipe to the two-position air valve switch using external pipelines. The external interface on the two-position air valve switch can then be used to connect to an external compressed air source, enabling the vacuum generator to be started and stopped by controlling the two-position air valve switch.

[0013] Furthermore, a silencer is provided at the rear end of the vacuum generator, and sound insulation cotton is filled around the vacuum generator inside the bottom frame;

[0014] By using the above technical solution, by installing a silencer on the outer wall of the vent pipe of the vacuum generator and filling the bottom frame and the area around the vacuum generator with sound insulation cotton, the exhaust noise and mechanical vibration noise of the vacuum generator during operation can be reduced, the working environment can be improved, and the operating comfort can be enhanced.

[0015] Furthermore, retaining rings are provided at both the upper and lower ends of the outer wall of the movable cylinder, and the inner wall of the movable cylinder is slidably connected to the guide rod.

[0016] The above technical solution connects the moving cylinder and the positioning frame with a retaining ring, allowing the positioning frame to slide up and down along the guide rod together with the moving cylinder.

[0017] Furthermore, the middle part of the outer wall of the movable cylinder is slidably connected to the positioning frame, the retaining ring is snapped into the positioning frame, and the upper end of the guide rod is threaded with a fixing bolt.

[0018] The above technical solution allows the positioning frame to be separated from the moving cylinder by opening the retaining ring and unfastening it. After unscrewing all the fixing bolts, the positioning frame can be removed, making it easy to replace different positioning frames.

[0019] Furthermore, the outer wall of the guide rod is fitted with a buffer spring, and the upper and lower ends of the moving cylinder are provided with a washer that is slidably connected to the guide rod. The upper end of the buffer spring is fixedly connected to the washer.

[0020] The above technical solution provides buffering force for the positioning frame through the buffer spring sleeved on the guide rod and the pads set at the upper and lower ends of the moving cylinder, protecting the product mirror from impact and assisting the positioning frame to reset after the film is applied.

[0021] This utility model has the following beneficial effects:

[0022] 1. The present invention proposes a double-sided film-applying device for a detector handle display. A vacuum zone is formed in the positioning base by a vacuum generator in the vacuum mechanism, which causes the protective film to be adsorbed. After the vacuum generator is turned off, the protective film is pressed onto the display mirror surface under the action of air pressure difference, and is completely adhered. This improves the flatness of the protective film, prevents wrinkles and bubbles, and avoids the need for subsequent processing to remove bubbles, thus saving manpower.

[0023] 2. The detector handle display double-sided film application device proposed in this utility model restricts the position of the display by means of a groove on the positioning frame in the positioning mechanism that matches the shape of the display, so that the film application area is aligned with the positioning base, thereby improving the positioning accuracy and avoiding the problems of traditional manual film application, which is prone to misalignment and may cause assembly interference, as well as the low efficiency caused by repeated correction of the position after film application.

[0024] 3. The detector handle display double-sided film application device proposed in this utility model uses an upper protective film and a lower protective film to form a single protective film, and sets a tear-off position on both. During operation, the upper protective film is first torn off, and then the product is placed on the lower protective film for film application. This avoids the problem of dirt caused by gloves or finger cots, and the aesthetics of the product mirror surface meet the given high requirements, while avoiding the secondary processing costs caused by dirt.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1-5 This utility model provides a specific implementation method:

[0034] A double-sided film application device for a detector handle display includes a base frame 1, a cover plate 2, an upper protective film 5, and a lower protective film 6. A fixing plate 3 is fixedly connected to the upper end of the cover plate 2. A vacuum mechanism 4 is provided inside the base frame 1. The vacuum mechanism 4 includes a vacuum generator 401 and a positioning base 404. An air inlet pipe 402 is fixedly connected to the air inlet of the vacuum generator 401. The middle part of the upper end of the fixing plate 3 is fixedly connected to the positioning base 404. The upper end of the positioning base 404 has multiple vacuum suction holes 405. The front of the positioning base 404... The outer wall of the tank is connected to an exhaust connection pipe 403. The lower end of the exhaust connection pipe 403 passes through the cover plate 2 and is fixedly connected to the vacuum port of the vacuum generator 401. The upper end of the fixing plate 3 is provided with a positioning mechanism 8. The positioning mechanism 8 includes a positioning frame 801 and four moving cylinders 803. The upper protective film 5 and the lower protective film 6 are both located in the positioning frame 801 and are fixedly connected to each other by adhesive. The upper protective film 5 and the lower protective film 6 are each provided with a separate protruding tear-off position 7. Guide rods 802 are fixedly connected to the four corners of the upper end of the fixing plate 3.

[0035] The vacuum generator 401 in the vacuum mechanism 44 creates a vacuum zone within the positioning base 404, causing the protective film to be adsorbed. After the vacuum generator 401 is turned off, the protective film is pressed onto the monitor mirror surface under the action of air pressure difference, achieving a complete fit. This improves the flatness of the protective film, preventing wrinkles and bubbles, thus avoiding the need for subsequent bubble removal and saving manpower. Furthermore, the positioning frame 801 in the positioning mechanism 8 has a groove that matches the shape of the monitor, restricting the position of the monitor and ensuring that the film application area is directly aligned with the positioning base 404, improving positioning accuracy. This design avoids the problems of traditional manual film application, which is prone to misalignment, causing assembly interference, and low efficiency due to repeated corrections after application. Furthermore, by using an upper protective film 5 and a lower protective film 6 to form a single protective film, with tear-off points 7 on both, the upper protective film 5 is peeled off first, and then the product is placed on the lower protective film 6 for application. This avoids the problem of dirt caused by gloves or finger cots, ensuring the product's mirror-like appearance meets the required high standards, while also avoiding the cost of secondary processing due to dirt.

[0036] The upper end of the base frame 1 is fixedly connected to the cover plate 2 by multiple screws. The vacuum generator 401 is installed inside the base frame 1 and fixed with bolts. By using multiple screws to fix the base frame 1 and the cover plate 2 together, the two can be separated while ensuring a stable installation, facilitating subsequent maintenance and repair of the vacuum generator 401 inside the base frame 1. The front end of the air inlet connecting pipe 402 extends through the base frame 1 to the outside of the base frame 1. A two-position air valve switch 406 is provided in the middle of the front outer wall of the base frame 1. By allowing the air inlet connecting pipe 402 to extend out of the base frame 1, it is convenient for operators to connect the air inlet connecting pipe 402 to the two-position air valve switch using external pipelines. The valve switch 406 is connected to an external compressed air source via its external interface, allowing the vacuum generator 401 to be started and stopped by the two-position air valve switch 406. A silencer is installed at the rear end of the vacuum generator 401, and sound-absorbing cotton is filled around the vacuum generator 401 inside the bottom frame 1. By installing a silencer on the outer wall of the vent pipe of the vacuum generator 401 and filling the bottom frame 1 and the vacuum generator 401 with sound-absorbing cotton, the exhaust noise and mechanical vibration noise of the vacuum generator 401 during operation can be reduced, improving the working environment and enhancing operational comfort. (The last sentence appears to be incomplete and possibly refers to a different topic: "moving cylinder.") Both the upper and lower ends of the outer wall of the 803 are provided with retaining rings 804. The inner wall of the moving cylinder 803 is slidably connected to the guide rod 802. The retaining rings 804 connect the moving cylinder 803 to the positioning frame 801, allowing the positioning frame 801 to slide up and down along the guide rod 802 with the moving cylinder 803. The middle part of the outer wall of the moving cylinder 803 is slidably connected to the positioning frame 801, and the retaining rings 804 are snapped into the positioning frame 801. The upper end of the guide rod 802 is threaded with a fixing bolt 807. By opening the retaining rings 804, the snapping of the positioning frame 801 is released, allowing the positioning frame 801 to separate from the moving cylinder 803. After unscrewing all the fixing bolts 807, the positioning frame 801 can be removed for easy replacement with different positioning frames 801. The outer wall of the guide rod 802 is fitted with a buffer spring 806. The upper and lower ends of the moving cylinder 803 are fitted with a washer 805 that slides with the guide rod 802. The upper end of the buffer spring 806 is fixedly connected to the washer 805. The buffer spring 806 fitted on the guide rod 802 and the washer 805 at the upper and lower ends of the moving cylinder 803 provide buffering force for the positioning frame 801, protect the product mirror from impact, and assist the positioning frame 801 in resetting after the film is applied.

[0037] Working principle: When using the double-sided film application device for the handheld display of this detector, after the product injection molding is completed, the operator first places the single protective film in the square groove on the positioning frame 801 for positioning. Then, the two-position air valve switch 406 is opened, and the vacuum generator 401 in the bottom frame 1 starts to work. At this time, the air in the positioning base 404 is discharged through the exhaust connection pipe 403. The single protective film generates a strong adsorption force under the vacuum of the vacuum suction hole 405. The operator quickly tears off the upper protective film 5 with the tear-off position 7 by hand. The lower protective film 6 is left in the groove. The operator places the side of the handheld display that needs to be filmed into the contour groove on the positioning frame 801 and presses it down to the bottom. After it is fully pressed down, the two-position air valve switch 406 is turned off. At this time, the vacuum generator 401 stops vacuuming. After the lower protective film 6 drops naturally due to the pressure difference, it will stick to the mirror surface of the handheld display. Then, the handheld display is removed, and the entire film application operation is completed.
