Description

Technical Field

[0001] This utility model relates to the field of optical film production technology, specifically a flattening device for producing film optical films. Background Technology

[0002] Film optical films refer to one or more layers of dielectric or metal films coated or deposited on optical elements or independent substrates to change the transmission characteristics of light waves, including light projection, reflection, absorption, scattering, polarization, and phase change. Through these characteristics, film optical films can modulate the transmittance and reflectance of surfaces in different wavelength bands, giving light with different polarization planes different characteristics. They are widely used in various optical and optoelectronic technology fields, including optical instruments, display devices, optical communications, precision optical equipment, photovoltaics, and automotive decorative materials. During production activities, it is often necessary to flatten film optical films to ensure production quality.

[0003] The "flattening device for producing film optical films" disclosed in application number "202221702165.X" "includes a processing table, inside which are a fixed roller and a movable roller. The movable roller is located above the fixed roller and is movably connected to the inner wall of the processing table. The fixed roller is connected to the inner wall of the processing table through a bearing. This utility model first passes the right end of the optical film through the movable roller and the fixed roller. Then, a first hydraulic cylinder drives a clamping plate to move down and cooperate with an L-shaped plate to fix the optical film. Then, a motor drives a threaded rod to rotate. The two threaded rods rotate simultaneously under the linkage of the transmission component, driving the threaded block to move the L-shaped plate to the right. The clamping plate and the L-shaped plate pull the optical film together. The movable roller and the fixed roller can flatten the optical film. Then, the first hydraulic cylinder drives the movable roller to move down and fix the left end of the optical film. This makes it easy for workers to check the flattened optical film. The structure is simple and very convenient to use."

[0004] However, the above method still has the following drawbacks: the optical film can be fixed by moving rollers and clamps, but both moving rollers and clamps need to be driven by two hydraulic cylinders, which increases the cost and makes it difficult to ensure the synchronization of the hydraulic cylinders, which can easily lead to the tilting of moving rollers and clamps and poor stability.

By controlling the electromagnet 7 to be de-energized and demagnetized, the support spring 903 can transmit pressure to the optical film through the optical film plate 904, which can quickly fix the optical film. The rubber pad 905 can increase the adhesion and friction between the optical film plate 904 and the optical film. During the vertical movement of the optical film plate 904, the guide post 902 can guide the optical film plate 904 to prevent it from tilting. The guide post 902 can also limit the support spring 903 to prevent it from falling off.

[0030] In this embodiment, preferably, the support assembly 14 includes a shelf 1401, with support legs 1402 fixedly provided at the four corners of the top of the shelf 1401. The four corners of the bottom of the support frame 1 are respectively fixedly connected to the bottom of the four support legs 1402. An opening baffle 1403 is fixedly provided at the top of the shelf 1401, and the top of the opening baffle 1403 is fixedly connected to the operating port 2 at the bottom of the support frame 1. A ground wheel 1404 is fixedly installed at the four corners of the bottom of the shelf 1401, and one side of the ground wheel 1404 is provided with... It has wheel brakes, and the support frame 1 can be supported by the storage plate 1401 and the support leg 1402. The operating port 2 at the bottom of the support frame 1 can be reinforced by the opening baffle 1403. Objects can be stored by the storage plate 1401. When the storage plate 1401 is loaded with objects, the opening baffle 1403 can protect the objects. The support frame 1 can be moved by the ground wheel 1404, which makes it easy to move the support frame 1 to a designated location. The ground wheel 1404 can be locked by stepping on the wheel brake.

[0031] In this embodiment, preferably, a pad 11 is fixedly provided on the inner wall of one side of the bottom end of the support frame 1. The pad 11 and the fixed frame 3 are located on the same vertical plane. A slide plate 12 is slidably connected to the inner wall of the other side of the bottom end of the support frame 1. The slide plate 12 and the sliding frame 4 are located on the same vertical plane. The slide plate 12 and the pad 11 are located on the same horizontal plane. Guide strips 13 are fixedly provided on both sides of the bottom end of the slide plate 12. Two guide grooves 15 are opened on the inner wall of the other side of the bottom end of the support frame 1. The guide strips 13 are slidably connected to the inside of the guide grooves 15. The optical film can be supported by the pad 11 and the slide plate 12. When the sliding frame 4 drives the film pressing assembly 9 to move, it can drive the slide plate 12 to move and tighten the optical film.

[0032] In use, during the processing of the optical film, firstly, the electromagnet 7 is energized and made magnetic. The electromagnet 7 attracts the adsorption plate 8. The adsorption plate 8 can lift the optical film pressure plate 904 through the horizontal plate 901 of the film pressing assembly 9. The optical film pressure plate 904 can compress the support spring 903. The support spring 903 can store energy. Then, the optical film is laid on the bottom of the optical film pressure plate 904 through the operation port 2. Then, the electromagnet 7 is de-energized and made to lose its magnetism. The support spring 903 can transmit pressure to the optical film through the optical film pressure plate 904, which can quickly fix the optical film. The rubber pad 905 can increase the adhesion and friction between the optical film pressure plate 904 and the optical film, and improve the fixing effect of the optical film.

[0033] After the optical film is fixed, the pad 11 and the slide plate 12 can support the optical film. The operator controls the extension rod of the electric push rod 501 to extend. The extension rod of the electric push rod 501 pushes the sliding seat 503 to move horizontally. The sliding seat 503 can drive the sliding frame 4 to move horizontally, which increases the distance between the sliding frame 4 and the fixed frame 3, so that the two pressing film assemblies 9 can tighten the film optical film. During this process, the slide rail 6 can guide the sliding block 506, which can ensure the linear movement of the sliding block 506.

[0034] During the movement of the sliding frame 4, under the action of pressure, the optical film pressure plate 904 at its bottom can transmit the pressure to the slide plate 12 and drive the slide plate 12 to move synchronously, avoiding sliding friction between the optical film and the slide plate 12, thus tightening the optical film and quickly unfolding it, which can ensure the production quality of the optical film.

[0035] During operation, the opening baffle 1403 of the support component 14 can reinforce the operating port 2 at the bottom of the support frame 1. The shelf 1401 can provide stable support for the support frame 1 through the support legs 1402 and the opening baffle 1403, making the support frame 1 less prone to shaking. Workers can store objects through the shelf 1401. When the shelf 1401 is loaded with objects, the opening baffle 1403 can protect the objects. When the support frame 1 needs to be moved, the worker can release the wheel brake of the ground wheel 1404 and move the support frame 1 through the ground wheel 1404. After the support frame 1 is moved to the designated location, the worker can step on the wheel brake of the ground wheel 1404 to lock the ground wheel 1404 and prevent the shelf 1401 from shifting.
