Description

Technical Field

[0001] The present invention relates to the technical field of tablet computer surface coating, in particular to a surface coating device for tablet computer production. Background Art

[0002] Tablet PC surface laminating equipment is a device specifically designed to laminarize tablet screens during the tablet production process. The purpose of this equipment is to improve the screen quality, abrasion resistance, and scratch resistance of the product, as well as provide an additional layer of protection against the intrusion of external factors such as moisture and dust.

[0003] The Chinese patent application with application number CN202311602039.6 discloses a laminating device for producing and processing tablet computer covers, comprising two U-shaped bases and a chain conveyor, wherein a connecting plate 1 is provided in the middle of the inner bottom wall of the opening of the two U-shaped bases, and the two connecting plates 1 are provided with connecting parts at the ends close to each other, and a rotating ring is provided on the side close to each other of the two connecting parts, and six storage mechanisms for transporting tablet computer covers are evenly provided on the outer surface of the rotating ring. The laminating device for producing and processing tablet computer covers described in the present invention uses a migration mechanism to enable the film placing mechanism to approach the rectangular cutting knife when the pushing mechanism moves downward, thereby minimizing the waste caused by the tablet computer cover during the downward laminating process, and the rectangular cutting knife can directly cut the film around the tablet computer cover, thereby directly completing the laminating of the tablet computer cover and reducing secondary cutting and trimming.

[0004] Although such a setting can directly cut the film around the tablet cover and directly complete the lamination of the tablet cover, and can also reduce secondary cutting and trimming, during the lamination process of the tablet screen, if there are dust particles on the screen, the particles will cause the lamination to bulge, resulting in certain bubbles in the lamination, which will affect the lamination effect and the protection of the tablet screen to a certain extent. Therefore, the surface of the tablet screen needs to be cleaned before lamination. Summary of the Invention

[0014] The purpose of the above setting is to place the flat plate on the rack, and a film is provided on the sliding coating assembly. The sliding coating assembly is driven to move by the driving assembly. The surface of the flat plate is coated during the movement of the sliding coating assembly. The adjustment assembly is adjusted to cut both sides of the flat plate. The sprinkler assembly cooperates with the rack track to allow the sprinkler assembly to spray water on the screen of the flat plate. The sliding coating assembly pushes the pump air assembly to operate and blow air. The air flow blows away the water droplets on the screen, and then the mop is dragged on the upper surface of the flat plate. During the dragging process, the water droplets are mixed with the dust on the screen, and then the mop pushes the dust mixture to one end of the flat plate and onto the leak baffle, thereby cleaning the upper surface of the flat plate, thereby reducing bubbles during coating. The through hole cooperates with the limit block to release the limit of the limit block on the film cutting assembly. The film cutting assembly cuts the film to complete the coating.

[0015] Furthermore, the driving assembly includes a motor and a screw, the motor is mounted on the outer wall of the frame, and the two ends of the screw are rotatably connected to the two ends of the bottom of the frame respectively;

[0016] The sliding coating assembly includes a sliding frame, the sliding frame is slidably connected to the frame, and the screw rod passes through the sliding frame and is threadedly connected;

[0017] The purpose of the above arrangement is to drive the screw to rotate by the motor, and the screw drives the sliding frame, so that the sliding frame and the supporting frame move on the frame.

When one end of the film contacts the screen of the flat plate, it sticks to one end of the screen of the flat plate, and then pulls the roller to rotate, and the conveyor belt is used to transport it. Then the pressure roller rolls the film flat to reduce the generation of bubbles in the coating.

[0025] The purpose of the above setting is that in the initial state, the top of the limit block is on the inner side of the fixed frame slide, and one end of the tension spring pulls the film cutting knife. Since the limit block limits the film cutting knife, the film cutting knife has not yet slid on the slide of the fixed frame.

[0027] The purpose of the above setting is that when the film cutting knife moves to the position of the protrusion, the movement of the support frame causes the protrusion to push the limit block, and the limit block rotates on the support frame, so that the top of the limit block moves out of the slide groove of the fixed frame, releasing the limit on the film cutting knife. At this time, the tension spring pulls the film cutting knife, and the film cutting knife slides on the slide groove of the fixed frame to cut the film, and then passes through the roller to roll it to complete the lamination.

[0031] Furthermore, the mop is rotatably connected to the outer wall of the gear;

[0032] The purpose of the above setting is that after the water flows onto the flat screen, multiple water droplets will form on the screen.

[0038] (1) The present invention sets a watering assembly. During the movement of the support frame, the housing is driven to move. The gear and the rack track are meshed with each other. The gear drives the rotating shaft and the blade to rotate. A small cavity is formed between each two blades and the housing. The cavity is used to transport water. The water flows into the interior of the small cavity through the water inlet pipe and the water inlet, and then is discharged through the long water outlet slot and flows to the flat screen. After the water flows onto the flat screen, a plurality of water droplets are formed on the screen. During the movement of the housing, the mop is driven to move. The mop is rotated by force and moves to the screen film of the flat plate, dragging the water droplets on the flat screen. The water droplets are mixed with the dust on the screen. Then the mop pushes the dust mixture to one end of the flat plate and pushes it to the leak baffle, thereby cleaning the upper surface of the flat plate, thereby reducing bubbles during coating.

Then the pressure roller 304 rolls and flattens the film to reduce the generation of bubbles in the film coating. The connecting frame 305 and the pressure roller 304 slide on the moving groove of the sliding frame 301 to squeeze the first spring 306 to adapt to flat plates 10 of different thicknesses;

[0094] By rotating the bidirectional screw 801, the bidirectional symmetrical threads of the bidirectional screw 801 simultaneously drive the two sliders 802, thereby driving the two sliders 802 closer or farther away, thereby driving the two blades 803 closer or farther away, so that the width of the film can be adjusted according to the width of the flat plate 10. Considering the difference between the width of the film and the width of the flat plate 10, the film at the two end edges of the flat plate 10 is cut after adjustment;

[0095] During the movement of the support frame 302, the shell 602 is driven to move, the gear 601 is meshed with the rack track 12, and the gear 601 drives the rotating shaft 604 and the blade 605 to rotate. A small cavity is formed between every two blades 605 and the shell 602, and the cavity is used to transport water. The water flows into the interior of the small cavity through the water inlet pipe 603 and the water inlet 606, and then is discharged through the long water outlet slot 607 and flows onto the screen of the flat plate 10. After the water flows onto the screen of the flat plate 10, a plurality of water droplets will be formed on the screen. During the movement of the shell 602, the mop 15 is driven to move, and the mop 15 is forced to rotate. The mop 15 moves to the screen membrane of the flat plate 10 and drags the water droplets on the screen of the flat plate 10. The water droplets mix with the dust on the screen, and then the mop 15 pushes the dust mixture to one end of the flat plate 10 and pushes it to the leak baffle 14 The second spring 402 is used to reset the telescopic tube 401. After the gas inside the telescopic tube 401 is discharged, the gas flows to the valve body 501. The airflow pushes the valve core 503. The valve core 503 squeezes the third spring 502. The valve core 503 moves to open the port of the valve body 501. When the airflow flows through the one-way valve 5, there is a certain air pressure. The gas flows to the exhaust pipe 504 and is discharged through the air hole 5040 to the screen of the flat plate 10, blowing away the water droplets on the screen of the flat plate 10. The water droplets are spread on the screen of the flat plate 10, so that they can come into contact with more screen dust, thereby improving the cleaning efficiency of the mop 15 to a certain extent.

[0096] After the film cutting knife 703 is in the state of being limited by the limit block 13, the film cutting knife 703 has not slid on the slide groove of the fixing frame 701. When the film cutting knife 703 moves to the position of the protrusion 102, the movement of the support frame 302 causes the protrusion 102 to push the limit block 13, and the limit block 13 rotates on the support frame 302, so that the top of the limit block 13 moves out of the slide groove of the fixing frame 701, releasing the restriction on the film cutting knife 703. At this time, the tension spring 702 pulls the film cutting knife 703, and the film cutting knife 703 slides on the slide groove of the fixing frame 701 to cut the film, and then rolls through the roller 303 to complete the film coating.

[0097] At this time, the mop 15 is on the upper surface of the frame 1, and the setting of the leak hole baffle 14 creates a gap between the flat plate 10 and the frame 1. The driving component 2 drives the sliding coating component 3 to return, and the mop 15 falls into the gap, pushing the flat plate 10 onto the placement plate 9. The residue on the leak hole baffle 14 falls into the collection box 11 for collection.
