Description

Technical Field

[0001] This utility model relates to the field of automatic film application technology, and in particular to an automatic film application device. Background Technology

[0002] In today's industrial production and many product processing fields, film application technology is widely used to provide protection, decoration, or functional enhancement to the surface of various products. For example, screen protectors for electronic devices can prevent scratches, and car window films can provide heat insulation and sun protection. With the continuous growth of market demand and the increasing number of products, the requirements for the efficiency and quality of film application are becoming more and more stringent. Traditional manual film application methods can no longer meet the needs of large-scale, high-quality production. Against this background, automatic film application devices have emerged. As an automated film application solution, automatic film application devices, with the help of advanced mechanical structures, automated control technology, and intelligent detection systems, are committed to achieving high efficiency, accuracy, and stability in film application operations. As a result, they are gradually replacing traditional manual film application in many industries and have become key equipment for improving the level of film application technology.

[0003] Existing film application devices typically consist of several basic components, including a film material conveying system, a positioning system, and a bonding system. The film material conveying system often employs a roller conveying structure, relying on a motor to drive one or more sets of rollers to rotate, moving the film material along a set track from the roll to the film application work area. A simple tension adjustment device is also included. In terms of the positioning system, some devices utilize simple mechanical limiting structures, such as fixed blocks at the edge of the film application platform to limit the placement position of the object to be filmed, providing a basic positional reference for subsequent film application. The bonding system commonly employs a pressure-type bonding structure, using a cylinder or electric push rod to drive a flat bonding plate, pressing it down to bond the film material to the object's surface. Simultaneously, simple scrapers or rollers are used, and manual operation is employed to smooth the film material, expel as much air as possible, and achieve bonding between the film material and the object.

[0004] However, while existing film-applying devices possess basic film-applying functions, they still suffer from low operational efficiency in automotive parts film application. Due to their relatively simple mechanical structure and basic technical principles, the connection between each stage of the film-applying process is not smooth and efficient enough. The positioning is not precise enough, requiring a lot of manual assistance for adjustment, and the application process also depends heavily on the operator's skill level. This results in a significant time commitment to complete the film-applying operation, making it impossible to quickly apply high-quality film to numerous products and failing to meet the urgent demand for film-applying efficiency in today's large-scale production. Therefore, an automatic film-applying device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic film application device, which aims to improve the problems of existing film application devices that rely on relatively simple mechanical structures and basic automation levels, have insufficient positioning accuracy requiring frequent manual intervention, and whose application operations often depend on human skill. The overall film application process is not well connected, resulting in low work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic film application device includes a support column, a worktable fixedly connected to the top of the support column, a film machine mounted on the upper surface of the worktable, a connecting frame fixedly connected to one side of the worktable, a motor fixedly connected inside the connecting frame, a rotating mold fixedly connected to the output end of the motor, and a film application assembly mounted on the top of the worktable. The film application assembly is used for high-efficiency automatic film application.

[0008] The film application assembly includes a support rod, which is fixedly connected to the upper surface of the worktable. A crossbeam is fixedly connected to one side of the support rod, and a slide rail is fixedly connected to the bottom of the crossbeam. A slide rod is slidably connected inside the slide rail. A cylinder is fixedly connected to one side of the crossbeam, and a sliding frame is fixedly connected to the output end of the cylinder. One side of the sliding frame is fixed inside the slide rod. A second cylinder is fixedly connected to the upper surface of the sliding frame, and a sliding column is fixedly connected to the output end of the second cylinder. A fixing block is slidably connected to the outer wall of the sliding column, and a film application head is provided at the bottom of the sliding column. A limiting component is provided on the upper surface of the worktable for limiting the film material.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a fixed frame and a cylinder three. The bottom of the fixed frame is fixedly connected to the upper surface of the workbench, the cylinder three is fixedly connected to the bottom of the fixed frame, and a transmission block is fixedly connected to the output end of the cylinder three.

[0011] As a further description of the above technical solution:

[0012] The upper surface of the fixed frame is fixedly connected with two symmetrical slide rails, and one side of the transmission block is fixedly connected with a symmetrical limiting block.

[0013] As a further description of the above technical solution:

[0014] The limiting block has a limiting groove inside, and a transmission rod is rotatably connected to the lower surface of the limiting block;

[0015] As a further description of the above technical solution:

[0016] A connecting plate is rotatably connected to one side of the transmission rod, and a rotating shaft is fixedly connected to the bottom of the connecting plate;

[0017] As a further description of the above technical solution:

[0018] The rotating shaft rotates inside the fixed frame, and the bottom of the connecting plate is rotatably connected to a transmission rod.

[0019] As a further description of the above technical solution:

[0020] One side of the transmission rod is rotatably connected to the lower surface of one of the limiting blocks, and the transmission rod is used to drive one of the limiting blocks to move synchronously.

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

[0022] 1. In this utility model, a motor drives a rotating mold to rotate, achieving the effect of rotating and changing the mold position. The output end of cylinder one drives the sliding frame to slide back and forth, while the output end of cylinder two drives the sliding column to slide inside the fixed block, thereby achieving the effect of free movement of the film applicator head. By cooperating with the rotating mold, this invention solves the problem that traditional manual film applicator usually requires multiple people to work together, resulting in high labor costs and problems such as poor communication and coordination and time-consuming operation during multi-person collaboration, leading to low overall work efficiency. This invention improves work efficiency.

[0023] 2. In this utility model, the cylinder three drives the limiting block to slide on the surface of the slide rail two, thereby further driving the connecting plate to move. Under the action of the connecting plate, the transmission rod two moves synchronously, so that the left and right symmetrical limiting grooves move inward synchronously, thereby achieving the effect of effectively limiting the membrane material. This solves the problem that the membrane material will shift due to external force during the use of traditional equipment, and improves the stability and accuracy of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an automatic film-applying device, including a support column 1, which serves as the support structure for the entire device and its function is to stably support the various components on a workbench 2. The top of the support column 1 is fixedly connected to the workbench 2, and a film-applying machine 16 is provided on the upper surface of the workbench 2. Its function is to accurately lay the film on the surface of the item to be filmed. A connecting frame 3 is fixedly connected to one side of the workbench 2. The connecting frame 3 is connected to the support column 1 through a fixing component, providing greater support for the device. A motor 4 is fixedly connected inside the connecting frame 3, and a rotating mold 5 is fixedly connected to the output end of the motor 4. The rotating mold 5 is used to rotate and change the position of the processed workpiece and the unprocessed workpiece, making it convenient for the operator to operate. A film-applying component is provided on the top of the workbench 2, which is used for high-efficiency automatic film application.

[0033] The film application assembly includes a support rod 6, providing stable support. The support rod 6 is fixedly connected to the upper surface of the worktable 2. A crossbeam 7 is fixedly connected to one side of the support rod 6, and a slide rail 8 is fixedly connected to the bottom of the crossbeam 7. A slide rod 9 is slidably connected inside the slide rail 8. The cooperation between the slide rail 8 and the slide rod 9 allows for lateral movement on the surface of the worktable 2, thereby achieving precise film application. A cylinder 10 is fixedly connected to one side of the crossbeam 7. The cylinder 10 can be adjusted for extension and retraction by air pressure, thereby controlling the horizontal or vertical movement of the sliding frame 11. The cylinder 10 outputs... A sliding frame 11 is fixedly connected to the end of the slide. One side of the sliding frame 11 is fixed inside the slide rod 9. A cylinder 12 is fixedly connected to the upper surface of the sliding frame 11. The function of the cylinder 12 is to further improve the film application accuracy and ensure that the film material can accurately cover the target area. A sliding column 13 is fixedly connected to the output end of the cylinder 12. A fixing block 14 is slidably connected to the outer wall of the sliding column 13. A film application head 15 is set at the bottom of the sliding column 13, which is responsible for transferring the film material from the film material machine 16 to the object to be applied. A limit component is set on the upper surface of the worktable 2. The limit component is used to limit the film material.

[0034] Specifically, relying on traditional manual film application is not only extremely costly in terms of labor but also inefficient, making it difficult to complete production tasks on time. The workpiece is first placed inside the rotating mold 5. Driven by the motor 4, the output of the motor 4 acts on the rotating mold 5, causing the mold to rotate and achieving a change in the workpiece's position. Specifically, the motor 4 rotates the unfilmed workpiece to the processing area, switching its position with the filmed workpiece, facilitating subsequent operations. When the unfilmed workpiece is brought to the processing area, the cylinder 10 begins to function. It pushes the slide rod 9 along the slide rail 8, precisely moving the film application head 15 to the film application area. At this time, the power provided by the cylinder 10 ensures the smooth and precise positioning of the film application head 15, preparing it for further processing. In the film application process, cylinder 2 12 drives the sliding column 13 to slide along the inner wall of the fixed block 14 through its output end, further promoting the synchronous movement of the film application head 15. The function of cylinder 2 12 is to provide the driving force for the up and down movement of the film application head 15 and ensure that the film application head 15 maintains close contact with the film during the descent, thereby ensuring that the film is firmly adsorbed onto the workpiece surface. During the descent, the film application head 15 applies the film evenly and stably to the workpiece, completing the film adhesion process. Finally, cylinder 10 plays its role again, driving the film application head 15 to the designated film application area to complete the film application work on the workpiece, ensuring that the film application effect of each workpiece is consistent and the adhesion is high, avoiding deviations caused by asynchrony between components.

[0035] Reference Figure 3 - Figure 5The limiting component includes a fixed frame 17 and a cylinder 18. The bottom of the fixed frame 17 is fixedly connected to the upper surface of the worktable 2 to ensure that the entire limiting component can provide stable support during operation. The cylinder 18 is fixedly connected to the bottom of the fixed frame 17 and serves to drive the transmission block 19. The output end of the cylinder 18 is fixedly connected to the transmission block 19. The upper surface of the fixed frame 17 is fixedly connected to a left-right symmetrical slide rail 20. The transmission block 19 is fixedly connected to a left-right symmetrical limiting block 21 on one side. The slide rail 20 is fixed to the upper surface of the fixed frame 17 and is arranged symmetrically to ensure that the limiting block 21 can slide stably along the track during movement. The limiting block 21 has a limiting groove 22 inside to limit the movement of the membrane material and prevent the membrane material from shifting during operation. The lower surface of the limiting block 21 is rotatably connected to a transmission rod 23.

[0036] Specifically, when multiple membrane materials of different widths are required for application, in order to ensure that each membrane material can be stably transported and operated on the same application device, the main function of the limiting groove 22 is to ensure that the membrane material remains stable during movement and prevents it from shifting. For this purpose, a pneumatic control mechanism is adopted, which provides power through the output end of cylinder 18 to drive the transmission block 19 to move back and forth on the track. The back and forth movement of the transmission block 19 is the key to the movement of the entire system. Its function is not limited to directly driving the limiting block 21, but also transmits force to other components through mechanical transmission. Driven by the transmission block 19, the limiting block 21 slides along the outer wall of the slide rail 20. The limiting block 21 ensures that the membrane material is precisely controlled during movement and avoids shifting. The surface of the slide rail 20 provides a stable sliding surface to ensure that the limiting block 21 can move smoothly.

[0037] Reference Figure 3 - Figure 5 A connecting plate 24 is rotatably connected to one side of the transmission rod 23 to transmit force and ensure the balance and synchronization of the force. A rotating shaft 25 is fixedly connected to the bottom of the connecting plate 24. The rotating shaft 25 rotates inside the fixed frame 17. The other end of the rotating shaft 25 is installed in the support hole inside the fixed frame 17 through a rolling bearing to ensure that it can rotate smoothly. A transmission rod 26 is rotatably connected to the bottom of the connecting plate 24. The transmission rod 26 is connected to the limit block 21 to ensure that the limit block 21 can maintain precise synchronization during the movement. One side of the transmission rod 26 is rotatably connected to the lower surface of one of the limit blocks 21. The transmission rod 26 is used to drive one of the limit blocks 21 to move synchronously.

[0038] Specifically, the transmission rod 23, as a force transmission component, further transmits the power generated by the cylinder 18 to the connecting plate 24. When the connecting plate 24 is subjected to force, it drives the rotating shaft 25 to rotate synchronously. The rotation of the rotating shaft 25 is the key to the transmission. It not only drives the connecting plate 24 to move, but also causes the transmission rod 26 connected to it to make a reverse synchronous movement through the mechanical structure. Through the rotation of the rotating shaft 25 and the reverse movement of the transmission rod 26, the left and right limit blocks 21 can slide synchronously inward on the surface of the slide rail 20, thereby ensuring the positioning of the left and right limit blocks 21. This effectively limits the offset of the membrane material, maintains the stability and accuracy of the membrane material in motion, and ensures that the membrane material can run accurately and smoothly during the movement without offset, thereby improving the operational reliability and accuracy of the entire equipment.

[0039] Working Principle: When using this device, the workpiece to be coated is placed inside the rotating mold 5. The output of the motor 4 drives the rotating mold 5 to rotate, thus switching the positions of the coated and uncoated workpieces. When the uncoated workpiece is rotated to the processing area, cylinder 10 drives the slide rod 9 to slide inside the slide rail 8, thereby moving the coating head 15 to the coating area. After the coating head 15 reaches the designated position, cylinder 2 12 drives the sliding column 13 to slide on the inner wall of the fixed block 14, further driving the coating head 15 to move synchronously. During its descent, the coating firmly adheres to the workpiece. Finally, cylinder 10 moves the coating head 15 to the designated coating area to coat the workpiece. Through this movement, the coating process is highly efficient. Stable, all bonding positions, adhesion degree, and movements can achieve a high degree of consistency. When the film material is conveyed by the film material machine 16, the film material can be limited by the limiting groove 22 to prevent the film material from deviating during the movement. The output end of the cylinder 3 18 drives the transmission block 19 to move back and forth. When the transmission block 19 moves back and forth, it further drives the limiting block 21 to slide on the outer wall of the slide rail 20. At the same time as the limiting block 21 slides, the force is further transmitted to the connecting plate 24 through the transmission rod 1 23, so that the connecting plate 24 drives the rotating shaft 25 to move synchronously. The movement of the rotating shaft 25 will synchronously drive the transmission rod 26 to move synchronously in the opposite direction, so that the left and right symmetrical limiting blocks 21 slide inward synchronously on the surface of the slide rail 20, effectively preventing the film material from deviating.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
