Description

Technical Field

[0001] This utility model relates to the field of protective film production technology, and in particular to a device for surface polarization treatment of mobile phone protective films. Background Technology

[0002] A screen protector is a thin film used to protect the screen of a mobile phone. It can effectively prevent the screen from being scratched, dirty, or stained with fingerprints, while also reducing the risk of screen breakage.

[0003] During the production of mobile phone screen protectors, their surfaces need to be polarized. Polarization treatment involves applying an electric field or other methods to the surface of the screen protector to form a polarized layer with special properties, which improves the optical properties of the film, enhances its anti-fouling properties, increases its adhesion, and increases its scratch resistance.

[0004] In the prior art, dust easily adheres to the surface of the protective film before polarization treatment, and dust can only be cleaned on one side of the film during cleaning, which greatly affects the polarization treatment and reduces its quality. Utility Model Content

[0005] The purpose of this invention is to solve the problem that before the protective film polarization treatment, the surface of the protective film is easily contaminated with dust, and the dust can only be cleaned on one side of the mobile phone film during the dust removal process, which greatly affects the polarization treatment and reduces the quality of the polarization treatment. Therefore, a mobile phone protective film surface polarization treatment device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A surface polarization treatment device for mobile phone protective films includes a base and a polarizer mounted on the top of the base. A bracket is fixedly connected to the top of the base. The device also includes two adsorption rollers, both rotatably mounted on the bracket via a rotating shaft. Each adsorption roller has a cavity inside and air holes communicating with the cavity on its surface. A drive unit for driving the adsorption rollers to rotate is provided on the bracket. A vacuum fan is fixedly connected to the rear side of the base. The input end of the vacuum fan is connected to a three-way pipe communicating with the cavity of the adsorption roller. The adsorption roller is rotatably connected to the three-way pipe.

[0008] In order to drive the adsorption roller to rotate and adsorb the protective film, preferably, the driving unit includes a motor fixedly connected to the base, one of the rotating shafts fixedly connected to the output end of the motor, and transmission gears fixedly connected to both rotating shafts, and the two transmission gears meshing together.

[0009] In order to clean the dust on the surface of the protective film, preferably, the input end and output end of the vacuum cleaner are fixedly connected to an air inlet pipe and an air outlet pipe, respectively. The air inlet pipe is fixedly connected to a three-way pipe. A collection box is fixedly connected to the rear side of the base. The air outlet pipe is fixedly connected to and communicates with the collection box.

[0010] To further clean the dust from the protective film surface, preferably, a sliding seat is fixedly connected to the top of the bracket, a horizontally arranged guide rod is slidably mounted on the sliding seat, a connecting frame is fixedly connected to the guide rod, and two oppositely arranged non-woven fabrics are arranged on the connecting frame.

[0011] To further automatically clean dust from the protective film surface, a ring is fixedly connected to the circumference of the guide rod. A sliding groove is provided inside the sliding seat, and the ring is slidably connected to the inner wall of the sliding groove. A spring is installed between the ring and the inner wall of the sliding groove. A cam is rotatably mounted on the bracket via a drive shaft. The arc-shaped surface of the cam contacts one end of the guide rod. A bevel gear is fixedly connected to both the drive shaft and one of the rotating shafts, and the two bevel gears mesh with each other.

[0012] In order to deliver the protective film to the area below the polarizer, preferably, a conveyor belt is installed on the top of the base, and the polarizer is positioned directly above the conveyor belt.

[0013] Compared with the prior art, this utility model provides a surface polarization treatment device for mobile phone protective films, which has the following beneficial effects:

[0014] 1. This mobile phone screen protector surface polarization treatment device drives the adsorption roller to rotate through the drive unit to adsorb dust on the screen protector. At the same time, the dust suction fan is activated to create negative pressure at the adsorption roller. The adsorbed dust enters the inner cavity of the adsorption roller through the air hole and is then discharged through the three-way pipe. This can clean the dust on both sides of the screen protector and improve the quality of polarization treatment.

[0015] 2. The mobile phone screen protector surface polarization treatment device, by setting up non-woven fabric, drives the non-woven fabric to move laterally back and forth on the surface of the screen protector when the screen protector passes between two non-woven fabrics. This is driven by the rotating shaft, bevel gear, transmission shaft, cam, guide rod, ring, spring and connecting frame, thereby simulating the method of manual wiping to further clean both sides of the screen protector, improving the dust removal effect and further improving the quality of polarization treatment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not 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.

[0023] Example:

[0024] Reference Figures 1-4This utility model provides a device for polarizing the surface of a mobile phone protective film, including a base 1 and a polarizer 4 mounted on top of the base 1 for polarizing the surface of the protective film. Two sets of conveyor rollers are installed above the base 1 to transport the protective film to the area below the polarizer 4, with two rollers in each set. A conveyor belt 17 is installed on the top of the base 1 to assist in transporting the protective film, and the conveyor belt 17 can support the protective film. The polarizer 4 is positioned directly above the conveyor belt 17. A bracket 5 is fixedly connected to the top of the base 1. The device also includes two adsorption rollers 201 for adsorbing dust from the surface of the protective film. The adsorption rollers 201 are electrostatic adsorption rollers with a rubber coating. They generate static electricity through rotation, thus charging their surface. The dust on the protective film surface generally carries a weak static charge. When the electrostatic adsorption rollers approach the surface of the mobile phone protective film, the static charge on the roller surface interacts with the dust particles. The action generates attraction. Based on the opposite action of charges (i.e., positive and negative charges attract each other), the adsorption roller 201 can adsorb these charged dust particles. The two adsorption rollers 201 are arranged vertically and are rotatably mounted on the bracket 5 via the rotating shaft 203. The adsorption rollers 201 are arranged horizontally. The protective film is conveyed between the two adsorption rollers 201 by two conveying rollers. The adsorption roller 201 has a cavity inside and air holes 6 that communicate with the cavity on its surface. The air holes 6 are evenly distributed on the surface of the adsorption roller 201. The bracket 5 is equipped with a drive unit to drive the adsorption roller 201 to rotate. The dust collector 301 is fixedly connected to the rear side of the base 1. The input end of the dust collector 301 is connected to a three-way pipe 303 that communicates with the cavity of the adsorption roller 201. The adsorption roller 201 is rotatably connected to the three-way pipe 303. The negative pressure generated by the dust collector 301 is greater than the adsorption force between the adsorption roller 201 and the dust, so that the dust can be sucked away by the dust collector 301.

[0025] During operation, the protective film is passed between two adsorption rollers 201. The adsorption rollers 201 are driven to rotate by the drive unit to adsorb the dust on the surface of the protective film. At the same time, the dust suction fan 301 is started, which creates a negative pressure at the adsorption rollers 201. The adsorbed dust enters the inner cavity of the adsorption rollers 201 through the air hole 6 and is then discharged through the three-way pipe 303. This can clean the dust on both sides of the protective film and improve the quality of polarization treatment.

[0026] The drive unit includes a motor 202 fixedly connected to the base 1. One of the rotating shafts 203 is fixedly connected to the output end of the motor 202. Both rotating shafts 203 are fixedly connected to transmission gears 204. The two transmission gears 204 mesh with each other and drive the two adsorption rollers 201 to rotate in opposite directions. The input end and output end of the dust collector 301 are fixedly connected to an air inlet pipe 302 and an air outlet pipe 305, respectively. The air inlet pipe 302 is fixedly connected to a three-way pipe 303. Both the air inlet pipe 302 and the three-way pipe 303 are fixedly connected to the bracket 5. A collection box 304 is fixedly connected to the rear side of the base 1. The air outlet pipe 305 is fixedly connected to and communicates with the collection box 304. A collection chamber is provided inside the collection box 304. Dust falls into the collection chamber. The collection chamber can be disassembled and the dust inside can be emptied periodically.

[0027] During operation, the motor 202 is started, and its output end drives the shaft 203 connected to it to rotate. Under the transmission of the transmission gear 204, the two shafts 203 rotate in opposite directions, which in turn drives the two adsorption rollers 201 to reverse and adsorb dust on the surface of the protective film. At the same time, the dust suction fan 301 is started, and a negative pressure is formed at the adsorption roller 201. The dust enters the inner cavity of the adsorption roller 201 through the air hole 6, and then falls into the collection box 304 through the three-way pipe 303, the air inlet pipe 302 and the air outlet pipe 305 for collection, thereby cleaning the dust off both sides of the protective film.

[0028] A sliding seat 7 is fixedly connected to the top of the bracket 5. A horizontally arranged guide rod 8 is slidably mounted on the sliding seat 7. The guide rod 8 is slidably connected to the bracket 5. A connecting frame 9 is fixedly connected to the guide rod 8. Two non-woven fabrics 10 are arranged opposite each other on the connecting frame 9. The two non-woven fabrics 10 are wrapped with sponge and are arranged vertically. A ring 11 is fixedly connected to the circumference of the guide rod 8. A sliding groove 12 is opened inside the sliding seat 7. The ring 11 is slidably connected to the inner wall of the sliding groove 12. A spring 13 is installed between the brackets. A cam 15 is rotatably mounted on the bracket 5 via a drive shaft 14. The arc-shaped surface of the cam 15 contacts one end of the guide rod 8. The end of the guide rod 8 that contacts the cam 15 is set as a hemispherical shape. A bevel gear 16 is fixedly connected to both the drive shaft 14 and one of the rotating shafts 203. The two bevel gears 16 mesh with each other. When the protective film is a hard film, the non-woven fabric 10 wipes it. When the protective film is a soft film, the non-woven fabric 10 needs to be removed so that it does not wipe the film and thus prevents damage to the protective film.

[0029] During operation, when cleaning the protective film, the protective film is adsorbed by two adsorption rollers 201 and then enters between two non-woven fabrics 10. The protective film and the non-woven fabrics 10 rub against each other to wipe the film. At the same time, the drive shaft 14 is driven to rotate by the rotating shaft 203 and the bevel gear 16. The drive shaft 14 drives the cam 15 to rotate. The cam 15 drives the guide rod 8 to move laterally. The guide rod 8 drives the ring 11 to slide in the slide groove 12 and compress the spring 13. Then the spring 13 returns to its original position, driving the ring 11 to move in the opposite direction. The ring 11 drives the guide rod 8 to return to its original position, so that the guide rod 8 moves laterally back and forth. The guide rod 8 drives the non-woven fabric 10 to move laterally back and forth on the surface of the protective film through the connecting frame 9, thereby simulating the manual wiping method to further clean both sides of the protective film, improving the dust removal effect and further improving the quality of polarization treatment.

[0030] In use, the protective film is passed between two adsorption rollers 201. The motor 202 is started, and its output end drives the rotating shaft 203 connected to it to rotate. Under the transmission of the transmission gear 204, the two rotating shafts 203 rotate in opposite directions, which in turn drives the two adsorption rollers 201 to reverse and adsorb the dust on the surface of the protective film. At the same time, the dust suction fan 301 is started, and a negative pressure is formed at the adsorption rollers 201. The dust on both sides of the protective film enters the inner cavity of the adsorption rollers 201 through the air hole 6, and then falls into the collection box 304 through the three-way pipe 303, the air inlet pipe 302 and the air outlet pipe 305 for collection, thereby cleaning the dust on both sides of the protective film.

[0031] The initially cleaned protective film then enters between two non-woven fabrics 10, where friction between the protective film and the non-woven fabrics 10 is used to wipe it. Simultaneously, the drive shaft 14 is rotated by the rotating shaft 203 and the bevel gear 16. The drive shaft 14 drives the cam 15 to rotate, and the cam 15 drives the guide rod 8 to move laterally. The guide rod 8 drives the ring 11 to slide in the slide groove 12 and compress the spring 13. Afterward, the spring 13 returns to its original position, driving the ring 11 to move in the opposite direction. The ring 11 drives the guide rod 8 to return to its original position, causing the guide rod 8 to move laterally back and forth. The guide rod 8 drives the non-woven fabric 10 to move laterally back and forth on the surface of the protective film through the connecting frame 9, thereby simulating the method of manual wiping to further clean both sides of the protective film. Then, the protective film falls onto the conveyor belt 17 and is polarized by the polarizer 4.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
