Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and specifically relates to a cleaning equipment for manufacturing optical film materials. Background Technology

[0002] Optical thin films are optical elements that are formed by depositing one or more layers of thin films on the surface of various materials such as optical glass, optical plastics, optical fibers, and crystals, and that change the intensity, polarization state, and phase of transmitted or reflected light based on the interference effect of light within the thin film.

[0003] Cleaning equipment for optical film manufacturing is a specialized device used to clean optical film materials. During the production process, the surface of optical film materials will be contaminated with various pollutants, such as dust, grease, and particulate impurities. These pollutants will affect the performance of optical film materials, such as light transmittance and refractive index, so cleaning equipment is of utmost importance.

[0004] Currently, the cleaning equipment used in the manufacture of optical film materials mainly includes ultrasonic cleaning machines, spray cleaning equipment, and tank cleaning equipment. Tank cleaning is a common cleaning method in the manufacture of optical film materials. It sprays the cleaning liquid onto the surface of the optical film material at a certain pressure and angle through a nozzle. During the process of rinsing the surface of the film material, the cleaning liquid carries away the contaminants.

[0005] Tank cleaning is suitable for cleaning large-area optical films. When producing large-area optical protective films, spray cleaning equipment can efficiently complete the cleaning work. However, in long-term use, it has been found that if there are many or firmly attached impurities on the optical film, the cleaning fluid sprayed from the nozzle is difficult to remove the contaminants completely, resulting in insufficient cleaning.

[0006] To address the aforementioned problems, this utility model proposes a cleaning device for manufacturing optical film materials. Utility Model Content

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.

[0046] Please see Figures 1-4 The present invention provides the following technical solution: a cleaning device for manufacturing optical film materials, including a cleaning platform 1 and a cleaning mechanism 3, and a driving mechanism 4 for driving two sets of cleaning mechanisms 3 to move towards or away from each other. Support legs 2 are fixed at the four corners of the bottom surface of the cleaning platform 1. The cleaning mechanism 3 includes: a housing 31, a main channel 32, a liquid inlet 33, a nozzle 34, a cylinder 35, a cleaning strip 36, and a rubber scraper 37.

[0047] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, the outer shell 31 is movably disposed above the cleaning platform 1, the main channel 32 is fixed inside the outer shell 31, the liquid inlet 33 is connected to the main channel 32 and penetrates through the outer shell 31, multiple nozzles 34 are fixed at equal intervals along the length direction on the main channel 32, the cylinder 35 is fixed inside the outer shell 31, the cleaning strip 36 is fixed on the piston rod of the cylinder 35, and the rubber scraper 37 is bonded and fixed to the cleaning strip 36. With the above scheme, during use, a rotating roller is used to feed the material, allowing the optical film to pass through the inner space of the two sets of cleaning mechanisms 3, and then the drive motor is started. The mechanism 4 drives two sets of cleaning mechanisms 3 to move towards each other, bringing the cleaning mechanisms 3 closer to the optical film material. A water pump pumps cleaning agent into the inlet 33, which then enters the main channel 32 and is sprayed onto the optical film material from multiple nozzles 34 to rinse the optical film material, softening or directly washing away impurities adhering to it. In addition, the cylinder 35 is activated, and the piston rod of the cylinder 35 pushes the cleaning strip 36 to move, causing the rubber scraper 37 to come into contact with the optical film material. During the transfer of the optical film material, the rubber scraper 37 further scrapes away surface impurities, ensuring thorough cleaning and guaranteeing product quality.

[0048] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes: an infusion tubing 5 and a three-way valve 6. The two infusion tubing 5 are symmetrically distributed, and one end of the infusion tubing 5 is connected to the inlet 33. The three-way valve 6 is connected to the other end of the two infusion tubing 5. With the above solution, when in use, the water pump is connected to the three-way valve 6 through a pipe, and cleaning agent is pumped into the two infusion tubing 5 at the same time.

[0049] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the drive mechanism 4 includes: a support column 41, a top plate 42, a bidirectional threaded screw 43, and a drive motor 44. A fixing block 311 is fixed at the end of the outer shell 31. The support column 41 is fixed to the top surface of the cleaning platform 1 and passes through the fixing block 311. The top plate 42 is fixed to the top of the support column 41. The bidirectional threaded screw 43 is rotatably installed between the cleaning platform 1 and the top plate 42 and passes through the fixing block 311 and is connected to the fixing block 311 by thread engagement. The drive motor 44 is fixed to the top of the top plate 42 and is used to drive the bidirectional threaded screw 43 to rotate. With the above scheme, when in use, the drive motor 44 is started to drive the bidirectional threaded screw 43 to rotate. Under the thread engagement, the two sets of cleaning mechanisms 3 move towards or away from each other to adjust the vertical distance between the two sets of cleaning mechanisms 3.

[0050] Preferably, by Figure 1 and Figure 3As shown in this embodiment, there are two sets of drive mechanisms 4 symmetrically distributed, which are used to drive the cleaning mechanism 3 to move simultaneously from both ends. After adopting the above scheme, when in use, the two sets of drive mechanisms 4 drive the cleaning mechanism 3 to move simultaneously from both ends, the power distribution is uniform, and the stability of the cleaning mechanism 3 is greatly improved.

[0051] Preferably, by Figure 1 As shown, this embodiment also includes an n-type mounting bracket 7 and a hot air blower 8. The n-type mounting bracket 7 is fixed to the top surface of the cleaning platform 1, and the hot air blower 8 is installed on the horizontal part of the n-type mounting bracket 7. With the above solution, when in use, the hot air blower 8 is connected to a power source to generate hot air, which helps to soften impurities.

[0052] It should be noted that the temperature of the hot air blower 8 should not be too high during actual use to avoid damaging the optical film.

[0053] Preferably, by Figure 1 As shown, this embodiment also includes: a baffle frame 9, a recycling pool 10, and a recycling trough 12. The baffle frame 9 is fixed to the top surface of the cleaning platform 1 and is located below the cleaning mechanism 3. A discharge hole 101 is machined on the part of the cleaning platform 1 located inside the baffle frame 9. The recycling pool 10 is fixed to the bottom surface of the cleaning platform 1 at the position corresponding to the discharge hole 101. The recycling trough 12 is installed in the recycling pool 10 by a pull-out method, and a disassembly port 11 for the recycling trough 12 to pass through is provided on the end face of the recycling pool 10. With the above solution, when in use, the scraped impurities and cleaning agent will enter the recycling trough 12 from the discharge hole 101 for collection. The recycling trough 12 can be pulled out for cleaning, which is convenient to operate.

[0054] It should also be noted that a drainage hole 101 is designed on the outer shell 31 to discharge impurities and sewage. Since sewage does not move upward automatically, in actual use, the drainage hole 101 only needs to be machined on the lower part of the outer shell 31.

[0055] In other available embodiments of this utility model, the recycling tank 12 can also be connected to a sewage pump via a pipe to extract sewage and impurities from the recycling tank 12, eliminating the need to pull out the recycling tank 12 for cleaning, which is suitable for scenarios where the cleaning operation takes a long time.

[0056] Preferably, by Figure 1 and Figure 4As shown, this embodiment also includes a handle 121 and a limiting block 13. The handle 121 is fixed to one end of the recycling trough 12, and the limiting block 13 is pivotally mounted on the end face of the recycling pool 10. With the above solution, the recycling trough 12 can be easily pulled by the handle 121 during use. After the recycling trough 12 is pushed into the recycling pool 10, the limiting block 13 is rotated to make the limiting block 13 vertical. The limiting block 13 is used to limit the recycling trough 12 and prevent the recycling trough 12 from moving.

[0057] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the outer side of the recycling tank 12 abuts against the inner wall of the recycling pool 10. With the above solution, this close fit further improves the stability of the recycling tank 12 during use, avoiding unnecessary movement or shaking.

[0058] It should be noted that cylinder 35, drive motor 44 and hot air blower 8 are all commercially available conventional equipment with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0059] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0060] Components not described in detail in this article are existing technologies.

[0061] The working principle and usage process of this utility model: When using the cleaning equipment of this utility model, a rotating roller is used to feed the material, allowing the optical film material to pass through the inner space of the two sets of cleaning mechanisms 3.

[0062] Then, the drive motor 44 is started to drive the bidirectional threaded screw 43 to rotate, so that the two sets of cleaning mechanisms 3 move towards each other under the screw rotation action, so that the cleaning mechanism 3 gets closer to the optical film material.

[0063] Cleaning agent is pumped into the inlet 33 by a water pump. The cleaning agent enters the main channel 32 and is then sprayed onto the optical film material from multiple nozzles 34 to rinse the optical film material, softening or directly washing away the impurities adhering to the optical film material.

[0064] In addition, the cylinder 35 is activated, and the piston rod of the cylinder 35 pushes the cleaning strip 36 to move, so that the rubber scraper 37 is in contact with the optical film material. During the transmission of the optical film material, the rubber scraper 37 is used to further scrape off the surface impurities of the optical film material, ensuring thorough cleaning and guaranteeing product quality.

[0065] In another aspect of this utility model, the scraped impurities and cleaning agents will enter the recycling tank 12 through the discharge hole 101 and be collected. The recycling tank 12 can be pulled out for cleaning, which is convenient. The recycling tank 12 can also be connected to a sewage pump through a pipe to pump out the sewage and impurities in the recycling tank 12 without having to pull out the recycling tank 12 for cleaning. This is suitable for scenarios where the cleaning operation takes a long time.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
