Description

Technical Field

[0001] This utility model relates to the field of diaphragm cleaning devices, and more particularly to an antistatic optical diaphragm cleaning device. Background Technology

[0002] Optical films are thin, transparent or translucent materials used in optical equipment, typically in the manufacture of precision devices such as lenses, displays, and optical sensors. The surface of optical films is usually treated with a special coating to improve their light transmittance, anti-reflection properties, or abrasion resistance. During the production and processing of optical films, due to their extremely fine surface and susceptibility to external environmental influences, dust, dirt, and static electricity easily adhere to the surface. These contaminants not only affect the optical properties of the film but also the quality and performance of the product.

[0003] In the existing technology, the cleaning method for optical films is generally through dry wiping or wet wiping. Although this can remove some impurities from the surface, due to the presence of static electricity and tiny particles, it is often impossible to thoroughly clean the surface of the film. Moreover, the surface of optical films is relatively delicate, and during the wiping process, it is easy to cause scratches or coating peeling, thereby affecting the performance of the optical film.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an anti-static optical film cleaning device with good cleaning effect and automatic loading and unloading.

[0007] The film loading bin is located at the side end of the frame and is used to stack optical films to be cleaned. The adsorption loading mechanism is located above the film loading bin and the film conveying mechanism is located on the frame. The adsorption loading mechanism is used to pick up the optical films onto the film conveying mechanism.

[0008] The static elimination mechanism and the cleaning mechanism are respectively arranged at intervals along the conveying direction of the film conveying mechanism. The static elimination mechanism is used to perform static elimination treatment on the optical film.

[0009] The cleaning mechanism includes a blower pipe and an exhaust hood. Two sets of blower pipes are respectively located on the upper and lower sides of the film conveying mechanism. The blower pipes are used to blow high-pressure airflow onto the optical film. The exhaust hood is located on the blower pipes and is used to absorb the dust blown up on the optical film.

[0010] The adsorption and feeding mechanism is located at the discharge end of the film conveying mechanism. The adsorption and feeding mechanism is used to pick up and transfer the optical film that has completed the cleaning process.

[0011] The antistatic optical film cleaning device described above also includes a film feeding bin, which is located at the bottom of the adsorption feeding mechanism to collect stacked optical films that have undergone cleaning.

[0012] Using the above technical solution, in the antistatic optical film cleaning device, the static elimination mechanism includes an ion air bar and a protective cover. The two ion air bars are respectively arranged on the upper and lower sides of the film conveying mechanism. The ion air bars are used to blow charged air onto the optical film. The protective cover is arranged outside the ion air bars.

[0013] In the above-described antistatic optical film cleaning device, the film conveying mechanism is a roller conveying mechanism.

[0014] The antistatic optical film cleaning device described above also includes an upper roller conveyor frame, which is located above the roller conveyor mechanism.

[0015] The length of the upper roller conveyor frame is less than the length of the roller conveyor mechanism, and a clamping gap is formed between the upper roller conveyor frame and the roller conveyor mechanism.

[0018] The support frame is mounted on the machine frame, the lateral movement module is located on the top of the support frame, the movable end of the lateral movement module is connected to the lifting cylinder through a connecting plate, the movable end of the lifting cylinder is set downward and connected to the mounting plate, and a plurality of suction cups are mounted on the mounting plate, the suction cups being used to adsorb optical films.

[0019] Using the above technical solution, in the antistatic optical film cleaning device, the film loading bin and the film unloading bin have the same structure, both including a screw lifting module, a lifting plate and a guide rod;

[0020] The movable end of the lead screw lifting module is connected to the lifting plate to drive the lifting plate to move vertically. The lifting plate is used to carry the optical film. The guide rod is vertically mounted on the frame. The lifting plate is provided with a guide groove to facilitate the passage of the guide rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The adsorption feeding mechanism of this invention can pick up and feed the optical film onto the film conveying mechanism. The static elimination mechanism on the film conveying mechanism can remove static electricity from the surface of the optical film, preventing static electricity from attracting dust and thus enhancing the cleaning effect.

At the same time, the exhaust hood can adsorb the dust raised by the negative pressure, avoiding secondary pollution. Then, the adsorption unloading mechanism can transfer the cleaned optical film to the unloading position, thereby completing the cleaning process, ensuring that the surface of the optical film is clean and free of static electricity, achieving deep cleaning of the optical film, greatly improving the cleaning efficiency of the optical film, and reducing human operation errors.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 6As shown, this utility model embodiment provides an antistatic optical film cleaning device, including a frame 1, a film conveying mechanism 2, a film loading bin 3, an adsorption loading mechanism 4, an electrostatic elimination mechanism 5, a cleaning mechanism 6, and an adsorption unloading mechanism 7. The film loading bin 3 is located at the side end of the frame 1 and is used to stack optical films to be cleaned. The adsorption loading mechanism 4 is located above the film loading bin 3. The film conveying mechanism 2 is located on the frame 1 and is used to pick up the optical films onto the film conveying mechanism 2. The electrostatic elimination mechanism 5 and the cleaning mechanism 6 are respectively located along... The film conveying mechanism 2 is spaced apart in the conveying direction. The static elimination mechanism 5 is used to perform static elimination treatment on the optical film. The cleaning mechanism 6 includes a blower pipe 61 and an exhaust hood 62. Two sets of blower pipes 61 are respectively located on the upper and lower sides of the film conveying mechanism 2. The blower pipes 61 are used to blow high-pressure airflow onto the optical film. The exhaust hood 62 is located on the blower pipes 61 and is used to adsorb the dust blown up on the optical film. The adsorption and unloading mechanism 7 is located at the discharge end of the film conveying mechanism 2 and is used to pick up and transfer the cleaned optical film. The adsorption feeding mechanism 4 can pick up the optical film and smoothly feed it into the film conveying mechanism 2. The optical film can enter the static elimination and cleaning area through the film conveying mechanism 2. Under the action of the static elimination mechanism 5, the static electricity on the surface of the optical film is removed, preventing the static electricity from adsorbing more dust and dirt. Then, the cleaning mechanism 6 blows high-pressure airflow onto the optical film through the blow pipes 61 on the upper and lower sides to blow up the dust particles attached to the surface of the optical film. At the same time, the exhaust hood 62 is connected to the external negative pressure suction device, which can adsorb and collect these raised dust particles to prevent the dust from falling back onto the surface of the optical film, thereby improving the cleaning effect. Finally, the adsorption unloading mechanism 7 picks up and transfers the optical film from the film conveying mechanism 2 to complete the cleaning process. The whole process is automated, which not only improves the surface cleaning effect of the optical film, but also eliminates static electricity accumulation and prevents contaminants from re-attaching, thereby improving the cleanliness of the optical film and production efficiency.

[0035] like Figure 1 As shown, it further includes a film feeding bin 8, which is located at the bottom of the adsorption feeding mechanism 7, for collecting stacked optical films that have undergone cleaning treatment.

[0036] like Figure 1 and Figure 5As shown, the electrostatic elimination mechanism 5 further includes an ion air bar 51 and a protective cover 52. Two ion air bars 51 are respectively disposed on the upper and lower sides of the film conveying mechanism 2. The ion air bars 51 are used to blow charged air onto the optical film. The protective cover 52 is disposed outside the ion air bars 51. The ion air bars 51 can blow charged air to neutralize the positive and negative charges on the surface of the optical film, thereby eliminating static electricity on the film and preventing static electricity from attracting dust and fine particles. The protective cover 52 disposed outside the ion air bars 51 can protect the ion air bars 51 from external interference and prevent external impurities from entering the interior.

[0037] Furthermore, the diaphragm conveying mechanism 2 is a roller conveying mechanism.

[0038] like Figure 3 As shown, it further includes an upper roller conveyor frame 9, which is located above the roller conveyor mechanism. The length of the upper roller conveyor frame 9 is less than the length of the roller conveyor mechanism, and a clamping gap is formed between the upper roller conveyor frame 9 and the roller conveyor mechanism. This arrangement can support the optical film during the conveying process, prevent the optical film from shifting laterally during transportation, and thus improve the conveying stability of the optical film.

[0039] like Figure 2 As shown, the cleaning mechanism 6 further includes a first soft-bristle brush roller 63 and a second soft-bristle brush roller 64. The first soft-bristle brush roller 63 is disposed in the roller gap of the upper roller conveyor frame 9, and the second soft-bristle brush roller 64 is disposed in the roller gap of the roller conveyor mechanism. The soft-bristle brush roller has soft bristles that can gently brush the surface of the optical film during the conveying process to remove stubborn or difficult-to-blow microparticles, thereby more thoroughly cleaning contaminants on the surface of the optical film.

[0040] like Figure 1 As shown, the adsorption loading mechanism 4 and adsorption unloading mechanism 7 have the same structure, both including a support frame 41, a lateral movement module 42, a lifting cylinder 43, a mounting plate 44, and suction cups 45. The support frame 41 is mounted on the frame 1, and the lateral movement module 42 is located on top of the support frame 41. The movable end of the lateral movement module 42 is connected to the lifting cylinder 43 via a connecting plate. The movable end of the lifting cylinder 43 is positioned downwards and connected to the mounting plate 44. Several suction cups 45 are mounted on the mounting plate 44, and the suction cups 45 are used to adsorb optical films. The lateral movement module 42 can adjust the lateral position of the suction cups 45 to switch between the film conveying mechanism 2 and the loading / unloading position. The lifting cylinder 43 can adjust the height of the suction cups 45 to realize the suction or release action of the optical film.

[0041] like Figure 1 and Figure 6 As shown, the film loading bin 3 and film unloading bin 8 have identical structures, both including a screw lifting module 31, a lifting plate 32, and a guide rod 33. The movable end of the screw lifting module 31 is connected to the lifting plate 32 to drive the lifting plate 32 to move vertically. The lifting plate 32 is used to support the optical film. The guide rod 33 is vertically mounted on the frame 1, and the lifting plate 32 is provided with a guide groove 320 to facilitate the passage of the guide rod 33. The screw lifting module 31 can drive the lifting plate 32 to move vertically, thereby adjusting the height of the optical film to automatically adjust the storage and retrieval position of the optical film according to different operational needs. The guide rod 33 can provide guidance for the lifting plate 32, so that the lifting plate 32 maintains a stable movement trajectory during the lifting process and avoids deviation.

[0042] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
