Description

TECHNICAL FIELD

[0001] The application relates to the technical field of surface coating devices, in particular to a fingerprint-resistant chemical solution coating device for mobile phone screen production. BACKGROUND

[0002] The mobile phone screen glass is in contact with the user's fingers for a long time during use, and fingerprints are easily left on the screen surface, so it is necessary to use a chemical solution coating device to spray fingerprint-resistant chemical solution onto the screen surface for surface fingerprint-resistant treatment, so as to form a fingerprint-resistant film layer on the screen surface. The existing chemical solution coating device comprises a conveying assembly, a coating assembly and a surface baking assembly. During use, the conveying belt slowly rotates, the clamping assembly uses a suction cup to move the mobile phone screen from the stacking position to the mesh belt conveyor, the mesh belt conveyor drives the mobile phone screen to pass through the coating assembly and the baking assembly in turn, the coating assembly sprays the fingerprint-resistant chemical solution through the atomizing nozzle, and moves back and forth in the vertical direction perpendicular to the conveying direction of the conveying belt, so that the chemical solution is uniformly coated on the surface of the mobile phone screen. After the mobile phone screen passes through the surface baking assembly, the chemical solution is solidified on the screen surface, and the coating of the fingerprint-resistant chemical solution is completed.

[0003] However, in the process of using the traditional chemical solution coating device, there is a gap between the mobile phone screens placed on the conveying belt, and the chemical solution sprayed from the atomizing nozzle will fall onto the conveying belt. The part of the chemical solution gathers and solidifies to form convex powder particles on the surface of the conveying belt. On the one hand, the particles are easily scattered to the surface of the mobile phone screen whose chemical solution has not been solidified, which affects the quality of the subsequent solidification of the fingerprint-resistant layer. On the other hand, when the mobile phone is placed in the convex position, the bottom of the screen does not completely contact the top of the conveying belt. The atomizing nozzle moves back and forth, and the chemical solution sprayed from the nozzle will cause the part of the screen to shake, which will affect the uniformity of the chemical solution coating and the forming quality of the fingerprint-resistant layer of the screen. Frequent shutdown and disassembly of the mesh belt conveyor will cause downtime loss and increase maintenance costs. SUMMARY

[0004] The application provides a fingerprint-resistant chemical solution coating device for mobile phone screen production, which has the advantages of reducing the residual fingerprint-resistant chemical solution on the conveying belt, and solves the problem that the fingerprint-resistant chemical solution is easily gathered and solidified on the conveying belt at the intermittent position between the screens.

[0008] Further, the number of rotating rings is matched with the number of fixed blocks, the number of scraping strips is matched with the number of rotating rings, one side of the adjusting block is arranged as an inclined slope, a collecting box is fixedly arranged between the supports, the top of the stop block is in T shape and the top surface is an inclined slope.

[0009] Further, a connecting strip is slidingly arranged on one side of the fixed block, an adjusting spring is fixedly connected on one side of the fixed block close to the second side plate, and one end of the adjusting spring is fixedly connected with the corresponding connecting strip.

[0010] Further, a transmission rod is fixedly connected between adjacent rotating rings, a second gear is fixedly sleeved on one end of the rotating ring, a second screw is rotatably arranged on the bottom of the second side plate, a third gear is fixedly sleeved on the bottom of the second screw, a moving block is threadedly sleeved on the outer side of the second screw, a first rack is fixedly connected on one side of the moving block, the first rack and the second gear are intermeshed, a fourth rack is fixedly arranged on one side of the bottom of the support, and a fifth rack is fixedly arranged on the other side of the bottom of the support.

[0011] Further, the rotating ring is rotatably sleeved with the supporting rod, the ring body of the rotating ring is rotatably sleeved with the connecting plate, the fourth rack and the fifth rack can be intermeshed with the third gear, the fourth rack is located between the spraying mechanism and the surface curing mechanism, and the fourth rack and the fifth rack drive the third gear to rotate in opposite directions.

[0012] Furthermore, a fixed cylinder is fixedly connected to one side of the second side plate, a sliding plug is slidably sleeved on the inner side of the fixed cylinder, a moving rod is fixedly connected to the midpoint of one side of the sliding plug, a connecting block is fixedly connected to one side of the moving rod, a connecting seat is fixedly connected to one side of the fixed cylinder, a screw is rotatably installed on one side of the connecting seat, a gear is fixedly sleeved on one side of the screw, the connecting block is threadedly sleeved with the screw, a through hole is opened on one side of the fixed cylinder, a connecting hole is opened on the inner side of the support rod, several suction holes are opened on the top of the support plate, a rack is fixedly installed on one side of the top of the bottom of the bracket, and a rack is fixedly installed on the other side of the bottom of the bracket.

[0013] Furthermore, the number and position of the side holes are adapted to the number and position of the fixing blocks.

A balance spring is fixedly connected to the bottom of the movable plug, and the cavity of the fixed cylinder is connected to the cavity of the connecting cylinder.

[0015] The beneficial effects of this invention are as follows:

[0016] This application provides an anti-fingerprint coating device for mobile phone screen production. A transmission chain drives a support rod to rotate cyclically. As the support rod drives the support plate through the spraying mechanism, the coating solution falls into the gaps between adjacent mobile phone screens without obstruction, preventing it from accumulating and solidifying into powder during subsequent processing. This avoids the accumulation and solidification of coating solution on the top surface of the support plate. Simultaneously, an adjusting rod and adjusting block work together to drive multiple scrapers that rotate along the transmission chain path on the top surface of the block. When the scrapers reach the bottom, they extend to scrape away any residual coating solution or powder from the block surface, preventing powder from scattering onto the mobile phone screen surface and causing a decrease in the film quality during coating and curing.

[0017] This application provides an anti-fingerprint coating device for mobile phone screen production. Through the sequential engagement of gear number three with rack numbers four and five, the top surface of the stop block is flipped to its bottom surface before it passes the surface curing mechanism. This increases the distance between the top surface of the stop block and the heat source, making it less likely for residual coating on the stop block to solidify. This improves the efficiency of subsequent cleaning of residual coating, further prevents coating residue from solidifying, reduces the impact of powder formed by solidified coating on subsequent mobile phone screen processing, and increases the yield rate.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, as Figures 1-7 A fingerprint-resistant coating device for mobile phone screen production includes a bracket 1. (See reference...) Figure 1 A spraying mechanism 2 is fixedly installed on one side of the top of the bracket 1, and a surface curing mechanism 3 is fixedly installed on the other side of the top of the bracket 1. (See reference) Figure 2 Both sides of the bottom of the support frame 1 are equipped with conveyor rollers 4 that rotate via a pivot. The conveyor rollers 4 are driven to rotate by a drive motor, which is fixedly mounted on the support frame 1. The two conveyor rollers 4 are arranged in parallel, and two transmission chains 5 are connected between the two conveyor rollers 4 via a sprocket drive. The two transmission chains 5 are respectively located at both ends of the conveyor rollers 4, and several support rods 7 are arranged between the two transmission chains 5. Each end of the support rod 7 is fixedly fitted with a connecting plate 6. The connecting plate 6 is L-shaped and is fixedly connected to the corresponding transmission chain 5. Specifically, a single connecting plate 6 is fixedly connected to a single link of the corresponding transmission chain. (See reference...) Figure 7 A fixing block 8 is fixedly connected to the outside of the support rod 7.

[0030] The number of fixing blocks 8 is set to a certain extent, and there is a gap between the fixing blocks 8. The top of the fixing blocks 8 is fixedly connected to a support plate 9 for supporting the mobile phone screen. (See reference) Figure 5 The support rod 7 has several rotating rings 10 sleeved on its outer side. A stop block 11 is fixedly connected to the top of each rotating ring 10. The number of rotating rings 10 matches the number of fixed blocks 8, meaning a single fixed block 8 is located between two adjacent rotating rings 10. A first side plate 15 is fixedly connected to one side of the support rod 7, and a second side plate 18 is fixedly sleeved on the other side. An adjusting rod 16 is slidably connected to one side of the first side plate 15. The support rod also includes several scraper strips 12, which can be elastic scrapers. The number of scraper strips 12 matches the number of rotating rings 10. The adjusting rod 16 is fixedly connected to the corresponding scraper strip 12. (See reference...) Figure 6 A sliding rod 14 is provided on one side of the fixed block 8, see reference. Figure 5 The sliding rod 14 is slidably engaged with the corresponding stop block 11.

[0031] The sliding rod 14 can slide relative to the stop block 11 in the axial direction of the rotating ring 10. A connecting strip 13 is slidably provided on one side of the fixed block 8. The connecting strip 13 can slide in the axial direction of the support rod 7 without disengaging from the fixed block 8. The two sides of the bottom of the connecting strip 13 can contact the sliding rod 14 for transmission to drive the adjacent sliding rod 14 to move. An adjusting spring 34 is fixedly connected to one side of one of the fixed blocks 8 closest to the second side plate 18. One end of the adjusting spring 34 is fixedly connected to the corresponding connecting strip 13. The adjusting spring 34 is used to push the corresponding connecting strip 13 to slide away from the second side plate 18. An adjusting block 17 is fixedly provided on one side of the bottom of the bracket 1. One side of the adjusting block 17 is set as an inclined slope. A collection box is fixedly provided between the brackets 1. The position of the collection box corresponds to the position of the spraying mechanism and is used to collect the medicine falling from the gap between the screens.

[0032] When applying anti-fingerprint liquid coating to a mobile phone screen, the drive motor drives the conveyor roller 4 to rotate. The conveyor roller 4 drives the transmission chain 5 to rotate cyclically. The transmission chain 5 drives the connecting plate 6 to rotate along the rotation trajectory of the transmission chain 5. The two corresponding connecting plates 6 drive the support rod 7 between them to move. The support rod 7 drives the fixing block 8 to move. The fixing block 8 drives the corresponding support plate 9 to move. The support plate 9 located at the top of the transmission chain 5 moves horizontally. The conveying mechanism of the liquid coating device uses a suction cup to transport the mobile phone screen onto the support plate 9. The support plate 9 drives the mobile phone screen to move horizontally and pass through the spraying mechanism 2 and the surface curing mechanism 3 in sequence. The conveying mechanism at the unloading end takes out the processed mobile phone screen, completing the liquid coating operation on the mobile phone screen.

[0033] As the screen passes through the spraying mechanism 2, the sprayed liquid falls through the gaps in the phone screen. The separated support plate 9 supports the screen while the screen itself blocks the liquid from falling onto it, reducing the possibility of residue. Some liquid falls onto the stop block 11 and then into the collection box. When the transmission chain 5 moves the support rod 7, after the phone screen has been moved, to the bottom of the bracket 1 and its position corresponds to the position of the adjusting block 17, the adjusting rod 16 contacts the inclined surface of the adjusting block 17. The adjusting rod 16 continues to move relative to the adjusting block 17, causing the adjusting block 17 to push the adjusting rod 16 towards the side closer to the second side plate 18. The adjusting block 17... The sliding rod 14 moves, which drives the adjacent connecting bar 13 to move. The connecting bar 13 pushes the adjacent sliding rod 14 on the other side to move, so that several connecting bars 13 and sliding rods 14 move synchronously. The movement of the adjusting rod 16, connecting bars 13 and sliding rods 14 drives the corresponding scraper 12 to move. At this time, the side of the stop block 11 that contacts the spraying mechanism 2 to spray the medicine is driven to flip to the bottom. The scraper 12 scrapes off the medicine or powder remaining on the contact surface, reducing the residue of medicine and powder, further extending the maintenance cycle of the medicine coating device, and reducing downtime losses. After the adjusting rod 16 disengages from the adjusting block 17, the adjusting spring 34 drives the connecting bar 13 to reset, and the transmission drives the sliding rod 14 and adjusting rod 16 to reset.

[0034] Example 2, as Figures 1-8 Based on Embodiment 1, the rotating ring 10 is rotatably sleeved with the support rod 7, see reference. Figure 8 A transmission rod 23 is fixedly connected between adjacent rotating rings 10, see reference. Figure 7 The transmission rod 23 has a fan-shaped cross section and can rotate relative to the fixed block 8 within a rated angle range. When the rotating ring 10 rotates, it drives the adjacent rotating ring 10 to rotate synchronously through the transmission rod 23, so that several rotating rings 10 can rotate synchronously. Referring to 8, the ring body of the rotating ring 10 is rotatably sleeved with the connecting plate 6. One end of the rotating ring 10 is fixedly sleeved with a second gear 35. The bottom of the second side plate 18 is rotatably provided with a second screw 38, which can rotate circumferentially relative to the second side plate 18.

[0035] A third gear 37 is fixedly sleeved at the bottom of the second screw 38. The third gear 37 is located at the bottom of the second side plate 18. A moving block 39 is threaded onto the outer side of the second screw 38. The moving block 39 can slide relative to the second side plate 18 along the axial direction of the third gear 37. A first rack 36 is fixedly connected to one side of the moving block 39. The first rack 36 meshes with the second gear 35. A fourth rack 42 is fixedly installed on one side of the bottom of the bracket 1, and a fifth rack 43 is fixedly installed on the other side of the bottom of the bracket 1. Both the fourth rack 42 and the fifth rack 43 can mesh with the third gear 37. The fourth rack 42 is located between the spraying mechanism 2 and the surface curing mechanism 3, and the fifth rack 43 is located on one side of the surface curing mechanism 3. The fourth rack 42 and the fifth rack 43 drive the third gear 37 to rotate in opposite directions. (See reference...) Figure 8 The top of the stop 11 is T-shaped and the top surface is inclined to drain the medicine that falls on top.

[0036] During the horizontal movement of the connecting plate 6 driven by the transmission chain 5, before the support plate 9 drives the screen past the surface curing mechanism 3, the connecting plate 6 drives the second side plate 18 to move. The second side plate 18 drives the third gear 37 to move past the fourth rack 42. The fourth rack 42 and the third gear 37 mesh and drive the third gear 37 to rotate circumferentially relative to the second side plate 18. The third gear 37 drives the second screw 38 to rotate. The second screw 38 drives the moving block 39 to move axially. The movement of the moving block 39 drives the first rack 36 to move relative to the second gear 35. The first rack 36 drives the second gear 35 to rotate, thereby driving the corresponding rotating ring 10 to rotate. Several rotating rings 1 The synchronous rotation of 0 drives the top and bottom surfaces of the corresponding stop 11 to flip. When the stop 11 passes the surface curing mechanism 3, the distance between the heat source and the top surface of the stop 11 is increased, reducing the possibility that the residual medicine on the inclined surface of the top of the stop 11 will be cured. This makes it easier for the subsequent scraper 12 to scrape off the residue, further reducing the residue of medicine and the powder generated by the curing of medicine, and improving the reliability of the coating device. After passing the surface curing mechanism 3, the third gear 37 meshes with the fifth rack 43. The third gear 37 moves relative to the fifth rack 43. The fifth rack 43 drives the third gear 37 to rotate and reset. That is, the third gear 37 drives the second screw 38 to rotate and move the moving block 39 to reset.

[0037] Example 3, as Figures 1-8 Based on Embodiment 2, a fixing cylinder 24 is fixedly connected to one side of the second side plate 18, see reference. Figure 6A sliding plug 25 is slidably sleeved on the inner side of the fixed cylinder 24. A moving rod 26 is fixedly connected to the midpoint of one side of the sliding plug 25. The moving rod 26 extends out of the fixed cylinder 24. An air passage is left between the moving rod 26 and the fixed cylinder 24. A connecting block 30 is fixedly connected to one side of the moving rod 26. A connecting seat 27 is fixedly connected to one side of the fixed cylinder 24. A screw 28 is rotatably provided on one side of the connecting seat 27. A gear 29 is fixedly sleeved on one side of the screw 28. The connecting block 30 is threadedly sleeved with the screw 28. A through hole is opened on one side of the fixed cylinder 24. A connecting cylinder 31 is fixedly provided on one side of the top of the fixed cylinder 24. A movable plug 32 is slidably provided on the inner side of the connecting cylinder 31.

[0038] A balance spring 33 is fixedly connected to the bottom of the movable plug 32. The cavity of the fixed cylinder 24 is connected to the cavity of the connecting cylinder 31. The balance spring 33 is used to push the movable plug 32 away from the fixed cylinder 24 to maintain negative pressure. (See reference...) Figure 7 The support rod 7 has a connecting hole 19 on its inner side and a side hole 20 on one side. The number and position of the side holes 20 are adapted to the number and position of the fixing blocks 8. The support plate 9 has a connecting cavity 22 on its inner side and a connecting hole 21 in the fixing block 8. The cavity of the connecting cavity 22 communicates with the connecting hole 21, and the connecting hole 21 is connected to the corresponding side hole 20. The top of the support plate 9 has several adsorption holes that communicate with the connecting cavity 22. The connecting hole 19 communicates with the cavity of the fixing cylinder 24 through a through hole. A third rack 41 is fixedly installed on one side of the top of the bottom of the bracket 1. (See reference) Figure 2 On the other side of the bottom of the bracket 1, a second rack 40 is fixedly installed. Both the third rack 41 and the second rack 40 can mesh with the first gear 29 and drive the first gear 29 to rotate in opposite directions. The top surface of the support plate 9 is rectangular and the size of the rectangle is smaller than the size of the mobile phone screen to be processed. The second rack 40 is located on one side of the spraying mechanism 2, and the third rack 41 is located on one side of the surface curing mechanism 3.

[0039] Before the mobile phone screen placement and support plate 9 moves to the spraying mechanism 2, the first gear 29 contacts and meshes with the second rack 40. The second rack 40 drives the first gear 29 to rotate, the first gear 29 drives the first screw 28 to rotate, the first screw 28 drives the connecting block 30 to move axially, the connecting block 30 drives the moving rod 26 to move axially, and the moving rod 26 drives the sliding plug 25 to move away from the second side plate 18. This generates negative pressure in the connecting hole 19 and the connecting cylinder 31 through the through hole. The connecting hole 19 generates negative pressure at the adsorption hole through the side hole 20, the connecting hole 21, and the connecting cavity 22. This allows the phone screen to be adhered and fixed to the support plate 9. At this time, the balance spring 33 is in a contracted state, maintaining the negative pressure inside the fixing cylinder 24. This ensures that the subsequent spraying of anti-fingerprint solution will not cause the support plate 9 to vibrate due to contact with the part of the phone screen not supported by the support plate 9. This allows the support plate 9 to be set in a smaller size, ensuring the screen shielding effect and reducing the possibility of the atomized solution falling onto the side of the support plate 9 and the side of the block 11. This further reduces solution residue and prevents the powder formed after the solution solidifies from breaking and flying onto the uncured phone screen, affecting the film quality.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
