Description

Technical Field

[0001] This utility model relates to the field of metallized thin film production technology, and to an anti-deviation device for vacuum coating of metallized thin films. Background Technology

[0002] In fields such as electronic components and packaging materials, the demand for metallized thin films continues to rise due to their excellent barrier properties, conductivity, and lightweight characteristics. Vacuum deposition is the core technology for achieving thin film metallization. This process requires the evaporation or sputtering of metal raw materials in a high vacuum environment to deposit them onto the surface of a plastic film, forming a uniform metal layer. The final product quality directly depends on the stability of the film during transport. If the film shifts, it will trigger a series of chain problems, severely restricting production efficiency and product qualification rate, becoming a key technical pain point that urgently needs to be solved in the industry.

[0003] In the current production of metallized thin film vacuum coating, the problem of film misalignment mainly stems from two core aspects: source positioning deviation and process transmission imbalance. The lack of precise positioning during the film roll installation stage causes the initial transmission trajectory to deviate from the preset path. Eccentricity causes the force radius to fluctuate with the roll diameter during film unwinding, resulting in inconsistent tension. This not only causes the film to slip and deviate on the transmission roller, but also causes uneven film edge output. At the same time, the lack of an efficient anti-deviation mechanism during film transmission leads to coating quality defects and production interruptions. When the film deviates, its relative position with the evaporation source and sputtering target changes, causing uneven metal layer thickness, defects such as material accumulation and incomplete coating, and increasing the product scrap rate.

[0004] To address the aforementioned issues, this application proposes an anti-deviation device for vacuum deposition of metallized thin films. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing an anti-deviation device for vacuum coating of metallized thin films.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A device for preventing deviation in vacuum coating of metallized thin films includes a vacuum coating machine body. A feeding roller is provided on the left side end of the vacuum coating machine body. A fixing sleeve is fixedly connected to the top of the vacuum coating machine body. A positioning component is provided on the vacuum coating machine body. An anti-deviation component is provided on the fixing sleeve. The anti-deviation component includes an extension plate, a smoothing rod, a smoothing tube, a third bidirectional threaded rod, an anti-deviation plate, and a fixing mechanism. The outer wall of the extension plate is slidably connected to the inner wall of the fixing sleeve. One side of the fixing sleeve is rotatably connected to the end point of the smoothing rod. One side of the extension plate is fixedly connected to the end point of the smoothing tube. One side of the extension plate is rotatably connected to the bottom end of the third bidirectional threaded rod. The outer wall of the third bidirectional threaded rod is threadedly connected to the inner wall of the anti-deviation plate. The outer wall of the anti-deviation plate is slidably connected to a groove opened on the third bidirectional threaded rod.

[0007] The fixing mechanism includes a first clamping plate, a pull ring, a torsion bar, and a second clamping plate. The outer wall of the torsion bar is slidably connected to the inner wall of the third bidirectional threaded rod. The outer wall of the extension plate is fixedly connected to one side of the second clamping plate. One end of the torsion bar located outside the third bidirectional threaded rod is fixedly connected to one side of the first clamping plate. The side of the first clamping plate away from the torsion bar is fixedly connected to the pull ring. By setting up the fixing mechanism, the third bidirectional threaded rod is fixed, preventing it from rotating again after the distance between the anti-deviation plates is adjusted. This avoids changes in the distance between the anti-deviation plates, thereby preventing damage to the film caused by the anti-deviation plates or affecting the anti-deviation effect of the anti-deviation plates on the film.

[0008] The positioning component includes a servo motor, a first bidirectional threaded rod, a telescopic plate, and an adjustment mechanism. The outer wall of the servo motor is fixedly connected to the outer wall of the feeding roller. The rotating shaft of the servo motor is fixedly connected to one end of the first bidirectional threaded rod. The end of the first bidirectional threaded rod away from the servo motor is rotatably connected to the vacuum coating machine body. The outer wall of the first bidirectional threaded rod is threadedly connected to the bottom end of the telescopic plate. The bottom end of the telescopic plate is slidably connected to a groove provided on the vacuum coating machine body. By setting the positioning component, the film cylinder is positioned so that it is positioned at the center of the feeding roller, thereby ensuring that the initial transmission trajectory of the film is centered and reducing the causes of source deviation.

[0009] The adjustment mechanism includes a first electric push rod, a movable plate, and a connecting member. The bottom outer wall of the first electric push rod is fixedly connected to a hole opened on the body of the vacuum coating machine. The telescopic end of the first electric push rod is fixedly connected to the bottom of the movable plate. The end point of the movable plate is slidably connected to the outer wall of the feeding roller. The outer wall of the telescopic plate is fixedly connected to the connecting member. The outer wall of the connecting member is slidably connected to a groove provided on the movable plate. By setting the adjustment mechanism, the positioning component can be adjusted so that the positioning component can adapt to different film cylinders.

[0010] The telescopic plate is fixedly connected to a rotating plate via the outer ring of a bearing. The outer wall of the rotating plate is in contact with the outer wall of the film cylinder on which the feeding roller is located. By setting the rotating plate, the friction between the film cylinder and the telescopic plate is reduced, thereby avoiding affecting the rotation of the film cylinder.

[0011] A second electric push rod is fixedly connected to the outer wall of the vacuum coating machine body, and an ear plate is fixedly connected to the outer wall of the extension plate. The bottom of the ear plate is fixedly connected to the top of the telescopic end of the ear plate. By setting the second electric push rod and the ear plate, the extension plate is lifted, which makes it convenient for the operator to pass the film through the smoothing tube and the smoothing rod, and thus facilitates the smoothing rod and the smoothing tube to smooth the film.

[0012] A spring is fixedly connected to the inner wall of the hole provided in the third bidirectional threaded rod. One end of the spring is fixedly connected to the end of the torsion bar located inside the third bidirectional threaded rod. By setting the spring, the torsion bar can be reset, thus facilitating the automatic reset of the torsion bar after it is pulled.

[0013] The beneficial effects of this utility model are:

[0014] By setting up anti-deviation components, the film is prevented from shifting during transport, thus ensuring that the film is always on the preset transport path. This guarantees stable coating quality, avoids product defects, prevents film damage and equipment downtime caused by deviation, ensures continuous production, reduces film loss and equipment failure, and improves production efficiency.

[0015] By setting up positioning components, the film tube is positioned to the center of the unloading roller, thereby ensuring that the initial film transport trajectory is centered, reducing the causes of source deviation. At the same time, with the film in the center, it can ensure uniform unwinding tension, avoid deviation caused by tension fluctuations, and improve the alignment of the film edges, ensuring the accuracy of subsequent processes.

[0032] Working principle:

[0033] The anti-deviation device for vacuum coating of metallized thin films places the film tube on the feeding roller 2, and then moves the movable plate 8 through the first electric push rod 7. The movement of the movable plate 8 will move the telescopic plate 6 through the connecting piece 9. After the telescopic plate 6 is adjusted to the required position, the first bidirectional threaded rod 5 will be rotated by the servo motor 4. The rotation of the first bidirectional threaded rod 5 will realize the movement of the telescopic plate 6, thereby adjusting the film tube to the required position. After the film tube is adjusted, the second electric push rod 16 and the ear plate 17 will drive the extension plate 11 and the smoothing tube 13 to rise. At this time, the operator can pass the film through the smoothing rod 12 and the smoothing tube 13. After the film passes through, the operator will stretch the first clamping plate 18 and the torsion rod 20 through the pull ring 19, thereby realizing the rotation of the third bidirectional threaded rod 14, so that the anti-deviation plate 15 prevents the film from deviating. After the film is deviated, the film is passed through the vacuum coating machine body 1, thereby realizing the coating of the film.
