Description

Technical Field

[0001] This application relates to the field of polarizing film cleaning technology, and in particular to a polarizing film cleaning machine. Background Technology

[0002] A polarizing film is a special optical film whose core function is to filter out harmful glare from light vibrating in a specific direction (such as reflected light from water, snow, or road surfaces), allowing light to pass through only in one direction. This effectively reduces eye strain, enhances color saturation, and makes vision clearer and more comfortable. Polarizing films are used in lenses such as polarized sunglasses and polarized prescription lenses. Polarized sunglasses are the most common form, typically with the polarizing film sandwiched between two layers of lens material (CR-39, polycarbonate PC, etc.), a process known as "laminated lens manufacturing." Polarized prescription lenses provide polarization for users with refractive errors such as myopia and hyperopia. The manufacturing process is more complex, requiring the polarizing film to be bonded or injected onto a lens substrate with the prescribed prescription.

[0003] Effective cleaning of the lens polarizing film not only maintains the optical clarity of the lens, but also protects the integrity and polarization performance of the polarizing film, thereby extending the lifespan of the lens and ensuring that users always receive the best visual experience and eye protection. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a polarizing film cleaning machine that can effectively clean the polarizing film of lenses to maintain the optical clarity of the lenses and protect the integrity and polarization performance of the polarizing film, thereby extending the service life of the lenses and ensuring that users always obtain the best visual experience and eye protection.

[0005] To achieve the above objectives, this application adopts the following technical solution: This application provides a polarizing film cleaning machine, which includes: The film-coating mechanism includes a placement frame and a placement frame lifting mechanism. The placement frame is used to place vertically stacked polarizing films, and the placement frame lifting mechanism is connected to the placement frame to drive the placement frame to move up and down. The film feeding mechanism includes a film feeding conveyor belt, a suction cup, a suction cup lifting mechanism, and a suction cup translation mechanism. The suction cup is located above the film feeding conveyor belt. The suction cup lifting mechanism is connected to the suction cup to drive the suction cup to lift and lower. The suction cup translation mechanism is connected to the suction cup to drive the suction cup to translate back and forth along the direction from the upper film mechanism to the film feeding conveyor belt. The cleaning mechanism includes a lint roller, several sets of drive sponge rollers and several sets of cleaning rollers. The lint roller is located at the output end of the film feeding conveyor belt to feed the polarizing film into the first set of drive sponge rollers. Each set of drive sponge rollers includes two upper and two lower drive sponge rollers, and each set of cleaning rollers includes two upper and two lower cleaning rollers. A film storage mechanism, comprising a film storage cylinder that is open at the top and closed at the bottom.

[0006] As a preferred technical solution, the film-upper mechanism further includes a film-separating mechanism, which includes at least one film-separating paddle, and the film-separating paddle is fixedly disposed at the upper end of the film-upper mechanism.

[0007] As a preferred technical solution, the film-laying mechanism further includes a positioning mechanism, which includes four positioning rods, a turntable, two sets of connecting rods, two sets of positioning rod sliding blocks, and a rotating handle. The four positioning rods are arranged circumferentially on the outer periphery of the placement frame. Two positioning rods are fixedly installed on each set of positioning rod sliding blocks.

[0012] As a preferred technical solution, the end of the film storage tube away from the cleaning mechanism extends upward to form a baffle portion.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: The polarizing film cleaning machine of this application integrates a series of processes such as film loading, film feeding, cleaning, and film storage, realizing fully automated processing from stacked polarizing film raw materials to the finished product after cleaning. It avoids the cumbersome steps of manual film picking, positioning, and transportation in traditional methods, greatly reducing manual intervention and improving production efficiency.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, this application provides a polarizing film cleaning machine 1, which includes: a film loading mechanism 11, a film feeding mechanism 12, a cleaning mechanism 13, and a film storage mechanism 14.

[0018] like Figure 3 and Figure 4As shown, the film loading mechanism 11 is located in front of the polarizing film cleaning machine 1 and is used for storing and loading polarizing film. The film loading mechanism 11 includes a placement rack 111 and a placement rack lifting mechanism 112. The placement rack 111 is used to place vertically stacked polarizing films, and the placement rack lifting mechanism 112 is connected to the placement rack 111 to drive the placement rack 111 to rise and fall. In this application, the placement rack lifting mechanism 112 includes a lifting motor and a lifting linear film assembly. The output shaft of the lifting motor is connected to the screw of the lifting linear film assembly. The screw of the lifting linear film assembly drives its slider to rise and fall. The slider of the lifting linear film assembly is fixedly connected to the placement rack 111 to drive the placement rack 111 to rise and fall.

[0019] Furthermore, the film-applying mechanism 11 also includes a film-separating mechanism, which includes at least one set of film-separating paddles 113, fixedly disposed at the upper end of the film-applying mechanism 11. When the film-feeding mechanism 13 places the semi-finished polarizing film from the film-applying mechanism 11 into the cleaning mechanism 13, the film-separating paddles 113 will separate several adhered polarizing films, ensuring that the film-feeding mechanism 13 only picks up one polarizing film. In this application, the film-separating mechanism includes two sets of film-separating paddles 113 symmetrically arranged from left to right.

[0020] Furthermore, the film-laying mechanism 11 also includes a positioning mechanism, which comprises four positioning rods 114, a turntable 115, two sets of connecting rods 116, two sets of positioning rod sliding blocks 117, and a rotating handle 118. The four positioning rods 114 are circumferentially arranged on the outer periphery of the placement frame 111, which is cross-shaped. The four positioning rods 114 are respectively located at the four recessed corners of the placement frame 111 to accommodate the movement of the four positioning rods 114. Two positioning rods 114 are fixedly installed on each set of positioning rod sliding blocks 117. The two sets of positioning rod sliding blocks 117 are configured to slide relative to or towards each other. One end of each set of connecting rods 116 is hinged to the turntable 115, and the other end of each set of connecting rods 116 is hinged to the corresponding positioning rod sliding block 117. The rotating handle 118 is fixedly connected to the turntable 115. After rotating the handle 118 and rotating the turntable 115, the two sets of connecting rods 116 are driven to move, thereby causing the two sets of positioning rod sliding blocks 117 to move closer to each other in the front-back direction, so that the four positioning rods 114 clamp the periphery of the polarizing film, thereby achieving the center positioning of the polarizing film.

[0021] like Figure 5 and Figure 6As shown, the film feeding mechanism 12 includes a film feeding conveyor belt 121, a suction cup 122, a suction cup lifting mechanism 123, and a suction cup translation mechanism 124. The suction cup 122 is used to place the polarizing film from the film feeding mechanism 11 onto the film feeding conveyor belt 121, which in turn transports the polarizing film to the cleaning mechanism 13. The suction cup 122 is located above the film feeding conveyor belt 121. The suction cup lifting mechanism 123 is connected to the suction cup 122 to drive it to rise and fall, and the suction cup translation mechanism 124 is connected to the suction cup 122 to drive it to translate back and forth along the direction from the film feeding mechanism 11 to the film feeding conveyor belt 121. In this application, the suction cup lifting mechanism 123 is a lifting cylinder or the like, and the suction cup translation mechanism 124 is a translation cylinder or the like. Specifically, the suction cup translation mechanism 124 is connected to the suction cup lifting mechanism 123 to drive it to translate back and forth. The bottom of the suction cup lifting mechanism 123 is connected to the suction cup mounting frame 125 and can drive the suction cup mounting frame 125 to lift. Two sets of suction cups 122 are installed on the suction cup mounting frame 125, and each set of suction cups 122 is used to pick up a set of polarizing film in the film-upper mechanism 11.

[0022] like Figure 6 As shown, the cleaning mechanism 13 includes a lint roller 131, several sets of drive sponge rollers, and several sets of cleaning rollers. The lint roller 131 is located at the output end of the film feeding conveyor belt 121 to feed the polarizing film into the first set of drive sponge rollers. Each set of drive sponge rollers includes upper and lower drive sponge rollers, and each set of cleaning rollers includes upper and lower cleaning rollers.

[0023] Furthermore, several sets of cleaning rollers include sponge cleaning roller sets and cotton thread cleaning roller sets, with the sponge cleaning roller sets sprayed with cleaning fluid. Even further, the sponge cleaning roller sets are located behind the cotton thread cleaning roller sets. The polarizing film first passes through the cotton thread cleaning rollers; the main purpose of this step is to efficiently remove loose particles, dust, and other dry contaminants from the surface. The cotton thread cleaning rollers effectively encapsulate and carry away these hard particles, preventing them from having an "abrasive" effect on the film surface under the action of the liquid during the subsequent wet washing stage, thus eliminating a major potential cause of scratches. After pretreatment, the film then enters the area of ​​the sponge cleaning roller sets sprayed with cleaning fluid. At this time, the cleaning fluid can act more directly on stubborn organic stains such as fingerprints and grease, achieving deep dissolution and cleaning. Because large particulate impurities have been removed beforehand, the wet wiping process of the sponge cleaning roller sets is safer and more efficient.

[0024] Furthermore, the rear end of the cleaning mechanism 13 is equipped with at least one set of drive sponge rollers. This set of drive sponge rollers acts as a crucial bridge between the cleaning area and the subsequent film storage mechanism 14. It ensures that the cleaned polarizing film can be actively and smoothly led out of the cleaning mechanism 13 and accurately delivered to the next stage.

[0025] Furthermore, a guide ramp 15 is provided behind the cleaning mechanism 13 to guide the polarizing film to the film storage mechanism 14. The polarizing film is in a horizontal conveying state in the cleaning mechanism 13 and needs to be stored in the vertical film storage cylinder 141. The core function of the guide ramp 15 is to act as a physical guide track, guiding the film from horizontal movement to vertical movement along the ramp into the film storage cylinder 141 naturally and smoothly. This avoids the film from drifting, getting stuck, or folding due to loss of support at the transfer point, ensuring the accuracy of the transmission path.

[0026] In this application, the cleaning mechanism 13 includes a lint roller 131, a first set of drive sponge rollers 132, a second set of drive sponge rollers 133, a first set of cotton thread cleaning rollers 134, a first set of sponge cleaning rollers 135, a third set of drive sponge rollers 136, a second set of cotton thread cleaning rollers 137, a second set of sponge cleaning rollers 138, and two sets of fourth sets of drive sponge rollers 139 arranged in sequence.

[0027] The film storage mechanism 14 is located behind the polarizing film cleaning machine 1 and is used to store the finished polarizing film. The film storage mechanism 14 includes a film storage cylinder 141 that is open at the top and closed at the bottom.

[0028] Furthermore, the end of the film storage cylinder 141 furthest from the cleaning mechanism 13 extends upward to form a baffle portion 1411. The baffle portion 1411 acts as a physical limiter, providing a uniform and defined termination point for each polarizing film sliding into the film storage cylinder 141. Regardless of the speed at which the film slides in, it will eventually come into contact with the baffle portion 1411 and stop. This ensures that all films are neatly stacked together inside the cylinder with the baffle portion 1411 as the reference surface, effectively avoiding problems such as film scattering, staggering, or oblique placement caused by sliding inertia or uncertain position, greatly facilitating subsequent batch retrieval or automated operations.

[0029] The polarizing film cleaning machine 1 of this application operates as follows: 1. The placement rack lifting mechanism 112 drives the placement rack 111 to rise until the uppermost polarizing film on the placement rack 111 reaches the top of the upper film mechanism 11. 2. The suction cup 122 of the film feeding mechanism 12 picks up the polarizing film at the top of the placement rack 111 and places it on the film feeding conveyor belt 121. 3. The cleaning unit 13 cleans the polarizing film; 4. After cleaning, the polarizing film slides down from the guide plate 15 and enters the film storage mechanism 14 for storage.
