Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and particularly relates to a glass etching coating device. Background Art

[0002] Glass etching refers to the process of corroding the glass surface by chemical or physical methods to form specific patterns, textures or functional effects. This technology is usually used to change the appearance or surface properties of glass, enhance its functionality or decorative properties. Glass etching generally uses corrosive chemical substances such as fluorides and chlorides for corrosion. After covering the glass surface with paraffin, the paraffin is removed at the positions where etching is required, and hydrofluoric acid is applied to the etching positions.

[0003] For example, a mechatronic automation glass etching coating device disclosed in Chinese Patent Publication No. (CN112624626B) records: "Comprising a melting pool, a support mechanism is arranged above the melting pool, and a fixing mechanism is slidably connected inside the support mechanism. In this mechatronic automation glass etching coating device, the glass is adsorbed below the suction cup. By transmission and starting the electric push rod, the cooling plate can be lowered to make the cooling plate contact the glass, and the paraffin solution can be cooled through the heat conduction of the glass, so that the paraffin solution can be attached to the surface of the glass. After the attachment is completed, the driving motor rotates in the reverse direction, and the glass plate moves upward, so that the glass plate can be removed from the through groove. During the removal process, the excess paraffin can be scraped off by the scraper, so as to ensure the thickness of the paraffin coating layer and the uniformity of the paraffin coating layer at the same time, and solve the problem of uneven paraffin coating in the prior art."

[0004] In summary, the device still has the following technical problems: The device fixes the glass through the suction cup and cooperates with the lifting structure to soak the glass in the wax pool to complete wax attachment. However, when the glass is loaded onto the device, manual assistance is still required, and automatic and continuous loading and replacement of the glass cannot be achieved, which will greatly affect the processing efficiency. Therefore, it is necessary to propose a glass etching coating device. To solve the technical problems mentioned in the above patent, a new technical solution is provided. Summary of the Invention

[0036] As described in the background art, the device fixes the glass through a suction cup and cooperates with a lifting structure to immerse the glass in the wax pool to complete wax coating.

[0041] To enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings.

[0042] Embodiment 1:

[0043] Please refer to Figures 2 - 5 A glass etching coating device, which includes a paraffin liquid heating tank 1. A material conveyor belt 2 is arranged on one side of the paraffin liquid heating tank 1. A glass automatic feeding structure 3 is arranged on the side of the paraffin liquid heating tank 1 away from the material conveyor belt 2. A circulating conveying structure 4 is arranged at the top of the paraffin liquid heating tank 1. A coating transfer structure 5 is arranged inside the paraffin liquid heating tank 1. Two groups of the circulating conveying structure 4 and the coating transfer structure 5 are respectively arranged in mirror symmetry;

[0044] A glass carrier 7 is fixedly connected to the side of the paraffin liquid heating tank 1 away from the paraffin liquid heating tank 1. A conveying positioning frame 8 is fixedly connected to the top of the paraffin liquid heating tank 1. A top bearing plate 9 is fixedly connected to the top of the glass carrier 7.

[0045] Specifically, a glass limiting frame 10 is fixedly connected to the top of the top bearing plate 9. A rectangular conveying port 11 is opened through the bottom end of the glass limiting frame 10 close to the paraffin liquid heating tank 1. An avoidance groove 12 is opened on the top surface of the top bearing plate 9.

[0046] Specifically, a servo motor 13 is fixedly connected to the surface of the top bearing plate 9. The driving end of the servo motor 13 is rotatably connected to a first shaft rod 14. The first shaft rod 14 is rotatably arranged at the bottom of the top bearing plate 9. A second shaft rod 15 is rotatably connected to the bottom surface of the top bearing plate 9. One end of the first shaft rod 14 away from the servo motor 13 is fixedly connected to a first belt pulley 16. One end of the second shaft rod 15 close to the first belt pulley 16 is fixedly connected to a second belt pulley 17. The first belt pulley 16 and the second belt pulley 17 are synchronously rotatably arranged through a transmission belt 18. Two friction conveying wheels 19 are respectively fixedly connected to the surfaces of the first shaft rod 14 and the second shaft rod 15. The friction conveying wheels 19 pass through the avoidance groove 12 and extend to the upper surface of the top bearing plate 9 and are in close contact with the glass.

[0047] Specifically, a C-shaped open slot 20 is opened on the side of the top bearing plate 9 close to the paraffin liquid heating tank 1. A light rod 21 is fixedly connected to the inside of the C-shaped open slot 20. An arc-shaped limiting frame 22 and an active turning block 23 are rotatably connected to the surface of the light rod 21. The active turning block 23 is arranged inside the arc-shaped limiting frame 22. A first torsion spring 24 and a second torsion spring 25 are respectively sleeved on the surface of the light rod 21. Two ends of the first torsion spring 24 are respectively fixedly connected to the arc-shaped limiting frame 22 and the light rod 21. Two ends of the second torsion spring 25 are respectively fixedly connected to the arc-shaped limiting frame 22 and the active turning block 23.

[0048] Through the above structural design, when the device is used, the glass is first stacked inside the glass limit frame 10. After completion, the servo motor 13 is turned on by the controller 6. The servo motor 13 drives the first shaft 14 to drive the first pulley 16 to rotate. While the first pulley 16 rotates, the second shaft 15 and the first shaft 14 are driven to synchronously drive the friction conveying wheel 19 to rotate through the second pulley 17 and the transmission belt 18. While the friction conveying wheel 19 rotates, the bottom glass can be pushed out to the inside of the rectangular conveying port 11. When the glass is pushed out, the active flip block 23 is squeezed. After the active flip block 23 is squeezed The arc limit frame 22 is flipped upward and the second torsion spring 25 accumulates elastic potential energy. When the rear end of the rectangular conveying port 11 moves to the top of the arc limit frame 22, the active flipping block 23 stops being squeezed, causing the second torsion spring 25 to release its elastic potential energy and synchronously drives the arc limit frame 22 to flip upward to block the glass on the rear side. When the arc limit frame 22 flips upward, the first torsion spring 24 accumulates elastic potential energy. When the glass at the front end is separated from the active flipping block 23, the first torsion spring 24 releases its elastic potential energy. At this time, the first torsion spring 24 drives the arc limit frame 22 and the active flipping block 23 to rotate and reset. In this way, continuous feeding of glass can be achieved.

[0049] Embodiment 2:

[0050] The glass etching coating device provided in Example 1 is further optimized, specifically, as follows Figures 5 - 7 As shown, the top surface of the paraffin liquid heating box 1 is fixedly connected to a conveying and positioning frame 8, and the circulating conveying structure 4 includes a self-locking motor 27 fixedly connected to the conveying and positioning frame 8 away from the side of the glass supporting frame 7, and the transmission end of the self-locking motor 27 is rotatably connected to a first rotating rod 28, and the first rotating rod 28 is rotatably set on the inner wall of the conveying and positioning frame 8, and the inner wall of the conveying and positioning frame 8 is rotatably connected to a second rotating rod 29, and the surface of the first rotating rod 28 is fixedly connected to two driving gears 30, and the surface of the second rotating rod 29 is fixedly connected to two driven gears 31, and the driving gear 30 and the driven gear 31 are connected by a transmission chain 32, and the outer surface of the transmission chain 32 is fixedly connected to a plurality of glass conveying plates 33.

[0051] Specifically, the glass conveying plate 33 is in a Z-shape inclined at ninety degrees, and a longer end of the glass conveying plate 33 is disposed close to the glass supporting frame 7 .

[0052] Specifically, there are two groups of circulating conveying structures 4 and coating transfer structures 5, and the two groups of circulating conveying structures 4 and coating transfer structures 5 are mirror-symmetrically arranged inside the paraffin liquid heating box 1 and the conveying positioning frame 8, and the elastic coefficient of the third torsion spring 39 is greater than the elastic coefficient of the spring 45.

[0053] Through the above structural design, after the glass automatic feeding structure 3 pushes out the glass, it moves to the surface of the glass conveying plate 33. At this time, the controller 6 controls the self-locking motors 27 on both sides to drive towards each other for a certain distance and then stop. At this time, the next glass conveying plate 33 is flush with the top bearing plate 9, and the glass automatic feeding structure 3 continuously conveys the glass to the surface of the glass conveying plate 33.

[0054] Embodiment 3:

[0055] The glass etching and cladding device provided in Embodiment 1 and Embodiment 2 is further optimized. Specifically, as Figures 7 - 9 shown, electric lifting pumps 34 are fixedly connected to the front and rear sides of the paraffin liquid heating tank 1 respectively. The top of the electric lifting pump 34 is provided with a special-shaped lifting frame 35. One side of the special-shaped lifting frame 35 close to the inside of the paraffin liquid heating tank 1 is fixedly connected with a glass cladding support plate 36.

[0056] Specifically, a hinge seat 37 is fixedly connected to the bottom surface of the special-shaped lifting frame 35. A positioning rod 38 is fixedly connected to the inside of the hinge seat 37. The positioning rod 38 is rotatably connected to the output end of the electric lifting pump 34. A third torsion spring 39 is sleeved on the surface of the positioning rod 38. The two ends of the third torsion spring 39 are respectively fixedly connected to the hinge seat 37 and the output end of the electric lifting pump 34.

[0057] Specifically, air storage tanks 40 are fixedly connected to both sides of the conveying and positioning frame 8. An air outlet pipe 41 is fixedly connected to the top of the air storage tank 40. A flow limiting valve 42 is fixedly arranged inside the air outlet pipe 41. A longitudinal guide rod 43 is slidably connected to the inside of the air storage tank 40. The bottom end of the longitudinal guide rod 43 extends to the bottom of the air storage tank 40. A piston ring 44 is slidably connected to the inside of the air storage tank 40. The piston ring 44 is fixedly connected to the top end of the longitudinal guide rod 43. A spring 45 is arranged inside the air storage tank 40. The spring 45 is arranged above the piston ring 44. One end of the longitudinal guide rod 43 away from the piston ring 44 is fixedly connected with a pressure rod 46. The end of the pressure rod 46 away from the longitudinal guide rod 43 is in close contact with the top surface of the special-shaped lifting frame 35.

[0058] Through the above structural design, after the self-locking motor 27 rotates multiple times, the glass conveyor plate 33 at the bottommost end turns outward synchronously, causing the glass to contact the glass cladding support plate 36. At this time, the controller 6 controls the electric lift pump 34 to drive the glass cladding support plate 36 to descend through the special-shaped lifting frame 35, so that the glass is immersed in the melted paraffin in the paraffin liquid heating tank 1. While the special-shaped lifting frame 35 descends, the pressure rod 46 stops receiving the thrust. At this time, the spring 45 pushes the piston ring 44 to drive the longitudinal guide rod 43 and the pressure rod 46 to descend synchronously. While the piston ring 44 descends, it inhales the external air into the interior of the glass limit frame 10 through the air outlet pipe 41. While the electric lift pump 34 pushes the special-shaped lifting frame 35 to rise, one end of the special-shaped lifting frame 35 is blocked by the pressure rod 46. At this time, the electric lift pump 34 continuously pushes the special-shaped lifting frame 35 to rise. Since the rising speed of one end is less than that of the other end, the special-shaped lifting frame 35 tilts. At the same time, the third torsion spring 39 accumulates elastic potential energy. Since the pushing speed of the electric lift pump 34 is relatively fast and the gas release in the air storage tank 40 is relatively slow, the third torsion spring 39 can only slowly release the elastic potential energy. After the special-shaped lifting frame 35 tilts, the glass slides from the surface of the glass cladding support plate 36 to the surface of the material conveyor belt 2 for conveying. When the output end of the electric lift pump 34 resets and stops pushing the special-shaped lifting frame 35 to rise, at this time, the third torsion spring 39 slowly releases the elastic potential energy, and through the pressure rod 46 and the longitudinal guide rod 43, it pushes the piston ring 44 to rise inside the air storage tank 40 to squeeze and contract the spring 45. When the air inside the air storage tank 40 is exhausted, the special-shaped lifting frame 35 also returns to the horizontal state. In this way, automatic wax application can be carried out on the next glass.
