Description

Technical Field

[0001] This utility model relates to the field of removal device technology, specifically to a glass tube antireflection membrane removal device. Background Technology

[0002] In industries such as optics, electronics, and photovoltaics, glass tubes, with their excellent light transmission and chemical stability, have become key components in various equipment and modules. To reduce light reflection loss on the surface of the glass tube and improve light transmission efficiency, an anti-reflection coating is usually deposited on its outer or inner surface. By precisely controlling the film thickness and refractive index, this anti-reflection coating can significantly improve the transmittance of light in specific wavelength bands, ensuring the optical performance or energy conversion efficiency of the equipment.

[0003] During the production, processing, repair, refurbishment, or recycling of glass tubes, when the antireflective coating exhibits wear, aging, or coating defects, it needs to be removed to meet the requirements for subsequent recoating or direct use. Currently, commonly used methods for removing antireflective coatings in the industry include chemical dissolution, physical grinding, and laser cleaning.

[0004] However, using the above three methods, the antireflective membrane will generate a large number of impurities during the removal process. Some of these impurities are suspended in the solution and some are precipitated at the bottom of the container. This not only makes it difficult to clean them up and increases the difficulty of subsequent waste liquid treatment, but also causes the suspended impurities to be easily adsorbed on the surface of the glass tube when it is taken out of the solution, resulting in secondary contamination of the glass tube. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a glass tube antireflection film removal device, which solves the technical problem in the prior art that impurities are difficult to clean after the glass tube antireflection film is removed and that the glass tube is secondary contaminated due to contact between the impurities and the glass tube.

[0016] A lead screw is arranged along the height direction of the housing and is rotatably mounted on the housing. A second bevel gear is provided on the lead screw, which meshes with the first bevel gear. A threaded hole is provided on the filter plate, and the lead screw is threadedly connected to the threaded hole. The lead screw is used to drive the filter plate to slide.

[0028] Optionally, the bottom of the housing is provided with several casters.

[0029] The beneficial effects of the embodiments of this utility model are as follows:

[0030] This invention primarily utilizes the physical action of ultrasound, combined with the dissolving effect of a removal agent and temperature control, to achieve efficient and non-destructive peeling of the antireflective membrane from the glass tube surface. The "cavitation effect" and mechanical vibration generated by ultrasound in the liquid disrupt the adhesion between the antireflective membrane and the glass surface. Simultaneously, the synergistic effect of chemical and temperature enhancement prevents damage to the glass substrate. The combination of ultrasound and removal agents effectively removes the antireflective membrane from the glass tube while protecting the outer wall, preventing breakage or scratches. This application incorporates a filter plate that slides along the height of the enclosure, effectively solving the problem of difficult impurity collection and cleaning. Furthermore, several detachable supports are arranged at intervals along the length of the filter plate to support the glass tube. After the removal process, the antireflective membrane rests on the filter plate, effectively preventing secondary contamination from contact between the glass tube and impurities, thereby improving the removal success rate and the overall efficiency of the device.

Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0042] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0043] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] like Figures 1-8 As shown, this invention illustrates a glass tube antireflective film removal device according to one embodiment of the present invention. The device includes a housing 1, an ultrasonic generator, a heater 2, a filter plate 3, and a support 4. Specifically, the glass tube is 4m long and 145cm in diameter, and the antireflective film to be removed is wrapped around the outer wall of the glass tube. Therefore, the housing 1 is a 4m long container to accommodate the glass tube, and the housing 1 is used to hold the removal agent. It should be noted that the removal agent used in this application is an alkaline liquid; the glass tube with the antireflective film to be removed is placed horizontally inside the housing 1 and completely immersed in the removal agent; the ultrasonic generator is mounted on the housing 1. It should be noted that in some examples, this application mainly uses the physical action of ultrasound as the core, combined with the auxiliary dissolving effect of the removal agent and temperature control, to achieve the efficient and non-destructive peeling of the antireflective film from the surface of the glass tube. Its core logic is to use the "cavitation effect" and mechanical vibration generated by ultrasound in the liquid to destroy the bonding force between the antireflective film and the glass surface. At the same time, the effect is enhanced by chemical and temperature synergy to avoid damaging the glass substrate. Specifically, the vibration of ultrasound allows the cleaning agent to quickly penetrate to the interface between the antireflective film and the glass, dissolving the binder of the antireflective film and reducing the adhesion of the antireflective film. At the same time, the impact force generated by the cavitation effect acts on the glass tube, accelerating the detachment of the loosened antireflective film.

[0048] Heater 2 is installed on the inner wall of chamber 1. Heater 2 is mainly used to heat the removal agent in chamber 1. The increase in temperature can accelerate the chemical reaction rate, thereby accelerating the removal of the removal agent in chamber 1 and improving the efficiency of removing the anti-reflection membrane on the glass tube. Filter plate 3 is detachably installed in chamber 1 and slides against the inner peripheral wall of chamber 1. Filter plate 3 is used to catch the anti-reflection membrane that falls off the glass tube, preventing the detached anti-reflection membrane from coming into secondary contact with the glass tube and causing secondary pollution to the glass tube. Filter plate 3 also catches the detached anti-reflection membrane, making it convenient for subsequent collection and cleaning. There are several supports 4, which can be arc-shaped, V-shaped, or square, etc. They are mainly used to support the glass tube and prevent the glass tube from falling or breaking under the action of the ultrasonic generator and removal agent. Several supports 4 can be detachably installed on filter plate 3 for easy replacement after the support 4 is damaged. Several supports 4 are arranged at intervals along the length of filter plate 3 to make the support points of the glass tube uniform.

[0049] It should be further explained that although heating can enhance the removal effect of ultrasound, the temperature should not be too high to avoid excessive evaporation of the medium, which would require frequent water replenishment.

[0050] For example, such as Figure 3 As shown, the glass tube antireflective membrane removal device also includes a linear drive component 5. It should be noted that the linear drive component 5 can be a screw motor, a cylinder, or a hydraulic cylinder, etc. The linear drive component 5 is set on the side wall of the housing 1, and the filter plate 3 is set on the movable end of the linear drive component 5. After the antireflective membrane removal is completed, the linear drive component 5 drives the filter plate 3 to rise to the top of the housing 1, so that the removal agent remains in the housing 1 through the sieve holes on the filter plate 3, and the removed antireflective membrane remains on the filter plate 3 and rises to the top of the housing 1 with the filter plate 3. It is then cleaned up by a scraper or other cleaning device, so that the removal agent can be used multiple times, avoiding the problem of frequently adding large amounts of removal agent and improving the working efficiency of the device.

[0051] For example, such as Figure 2 and Figure 4As shown, in some examples, the linear drive 5 includes a motor 51 and a lead screw 52. The motor 51 is mounted on the side wall outside the housing 1, and the output shaft of the motor 51 extends through the side wall into the housing 1. A first bevel gear 511 is mounted on the output shaft and is located on the inner wall of the housing 1. A second bevel gear 521 is mounted on the lead screw 52. A threaded hole 301 is provided on the filter plate 3, and the lead screw 52 is threadedly connected to the threaded hole 301. Specifically, the lead screw 52 extends along the height of the housing 1. The filter plate 3 is vertically arranged at opposite corners in the direction of the angle. The lead screw 52 can rotate under the drive of the motor 51. The filter plate 3 is threadedly connected to the lead screw 52. Under the drive of the motor 51, the filter plate 3 moves up and down along the height direction of the housing 1 through the threaded hole 301 on the lead screw 52. The second bevel gear 521 meshes with the first bevel gear 511. Since the two shafts intersect, the power is transmitted from the output shaft of the motor 51 to the lead screw 52 after the two bevel gears mesh, thereby driving the filter plate 3 to move up and down.

[0052] It should be noted that threaded holes 301 are provided at the diagonal positions of the filter plate 3 to allow the filter plate 3 to follow the lead screw 52. Since the diagonal placement of the lead screw 52 would make the filter plate 3 unstable, smooth cylindrical rods are installed at the other two corners. The cylindrical rods are arranged parallel to the lead screw 52 and are located in the height direction of the housing 1. The length is the same as that of the lead screw 52. This is used to stabilize the filter plate 3 and not to hinder the lifting and lowering of the filter plate 3. This avoids the problem of the glass tube shifting or even falling due to the instability of the filter plate 3, which would affect the working efficiency of the device.

[0053] For example, such as Figure 3 As shown, the heater 2 is located below the filter plate 3 and is detachably mounted on the inner wall of the housing 1, which avoids hindering the lifting and lowering of the filter plate 3, and the detachable mounting facilitates repair or replacement after damage.

[0054] It should be noted that heater 2 is an electric heater. It includes two heating rods and two junction boxes. The two heating rods are respectively installed on the inner side wall of the box 1 and located below the filter plate 3, extending along the length of the box 1 towards the middle of the box 1. They heat the removal agent by electric heating, making the heating faster.

[0055] For example, such as Figure 1 As shown, in some examples, the glass tube antireflective film removal device also includes a heat insulation plate 6. There are several heat insulation plates 6, which are respectively installed around the outer wall of the box 1. When the heater 2 heats the removal agent to a certain temperature, the heat insulation plate 6 can keep the box 1 warm, prevent the heat from being lost too quickly, and keep the removal agent in the box 1 at a relatively stable temperature, thereby improving the success rate of antireflective film removal and making the antireflective film removal uniform and complete.

[0056] For example, such as Figure 8 As shown, in some examples, the bracket 4 includes a base 41 and a support plate 42. The base 41 is detachably mounted on the filter plate 3. The support plate 42 is mounted on the base 41 and is used to support the glass tube. This avoids the glass tube being placed directly inside the housing 1 and coming into contact with the detached antireflective membrane again, which would cause secondary pollution. When the ultrasonic generator is working, the "cavitation effect" and mechanical vibration generated by the ultrasonic waves in the liquid can cause damage or scratches to the outer wall of the glass tube, affecting the light transmittance of the glass tube and thus affecting the subsequent use of the glass tube.

[0057] For example, such as Figures 5-7 As shown, in some examples, the filter plate 3 is provided with several slots 302. Each slot 302 has an insertion port 3021 and a limiting groove 3022. The insertion port 3021 and the limiting groove 3022 are connected and arranged in a T-shape. The bracket 4 also includes a limiting post 7, which is set on the bottom surface of the base 41. A limiting protrusion 71 is provided on the bottom surface of the limiting post 7. Specifically, the limiting protrusion 71 is a cylinder that is adapted to the insertion port 3021 and is larger than the diameter of the limiting post 7. The diameter of the limiting post 7 is the same as that of the limiting groove 3022. The limiting protrusion 71 can slide into the limiting groove 3022 through the insertion port 3021, and the height of the limiting protrusion 71 is adapted to the depth of the slot 302. The limiting protrusion 71 slides to the deepest part of the limiting groove 3022 and is locked with the limiting groove 3022 to prevent the bracket 4 from shifting. The insertion port 3021 on the filter plate 3 cooperates with the limiting groove 3022 and the limiting protrusion 71 on the bracket 4 to clamp the bracket 4, so that the bracket 4 will not shift or fall during operation, thereby preventing the glass tube from shifting or falling.

[0058] For example, such as Figure 1 As shown, in some examples, the housing 1 also includes a top cover 8, which is a plurality of which are detachably mounted on the top surface of the housing 1. A plurality of handles 81 are provided on the top wall of the top cover 8. It should be noted that the top cover 8 is used to seal the housing 1, making the housing 1 a closed space, preventing the removal agent inside the housing 1 from splashing out due to ultrasonic vibration, and avoiding the problem that the removal agent is an alkaline liquid and may be dangerous to the human body.

[0059] For example, such as Figure 5 As shown, the bottom of the box 1 is equipped with several casters 9 to facilitate the movement of the box 1.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
