[0014] A high-reflective silk-screen backboard glass production process adopts the high-reflective silk-screen backboard glass production equipment, and specifically comprises the following steps.

[0015] S1: The back glass is pushed onto the upper surface of the fixed plate by the pushing device, and the moving part is moved to one side by the drive component to drive the threaded rod to rotate. The back glass is then clamped by the clamping component on the top of the moving part.

[0016] S2: During printing, the second connecting piece is lowered by the second pneumatic rod, and the movable part contacts the surface of the screen. The arc surface contacts the surface of the screen, and then the second servo motor moves the mounting bracket on one side of the movable plate. This allows the enamel on the surface of the screen to be printed onto the back glass surface through the printing area inside the screen. Then the second connecting piece is raised, and the first connecting piece is lowered by the first pneumatic rod, causing the movable head to contact the surface of the screen. The enamel flows out through the gap between the movable head and the inner wall of the second mounting piece, and is laid on the top of the screen by the movement of the mounting bracket.

[0017] S3: After the back panel glass printing is completed, the lifting frame is raised by the hydraulic rod, so that the conveyor enters the connecting groove inside the fixed plate until the screen-printed back panel glass is raised. Then, the dual-axis motor drives the drive shaft to rotate, so that the conveyor can transport the processed screen-printed back panel glass.

[0018] Compared with the prior art, the advantages of this invention are:

[0019] (1) This solution sets up a printing mechanism and a filter screen so that the glaze can be filtered when it flows into the second mounting part, thereby removing impurities and making the glaze more delicate. By setting up a silicone pad, the silicone pad can contact the surface of the back glass when the screen falls, limiting the printing range and preventing the glaze from being squeezed out of the printing area during the printing process. By setting a fixed frame and a movable frame on one side of the silicone pad, it can restrict the silicone pad and avoid deformation of the silicone pad due to excessive squeezing during the printing process. This can better ensure the printing quality of the back glass.

[0020] (2) This solution sets up a positioning mechanism, drives the threaded rod to rotate through the drive component to move the moving component to one side, and clamps the back glass through the clamping component at the top of the moving component. When the thickness of the back glass to be processed is adjusted, the worm gear is rotated by rotating the knob, which in turn rotates the worm wheel. When the worm wheel rotates, the threaded rod can be rotated through the internal thread groove, thereby adjusting the distance between the clamping component and the moving component, so that the clamping component is slightly lower than the back glass. This allows the back glass to be clamped and fixed without affecting the screen printing on the back glass.

[0021] (3) The scheme is provided with a conveying mechanism, when the back plate glass printing is completed, the lifting frame is lifted by the hydraulic rod, the conveying part is in the communication groove in the fixed plate, until the silk screen printed back plate glass is lifted, then the driving shaft is driven to rotate by the double shaft motor, so that the conveying part can convey the processed silk screen printed back plate glass, so as to prevent the silk screen printed pattern on the surface of the silk screen printed back plate glass from being contacted in the conveying process, and reduce the defects of the silk screen printed pattern on the surface of the silk screen printed back plate glass;

[0022] (4) The installation brush and the bristles on the side of the installation brush are arranged, when the glaze is sprayed on the surface of the silk screen, the bristles can smooth the glaze on the surface of the silk screen, so that the glaze is uniformly laid on the printing area in the silk screen.

[0042] In some embodiments, referring to Figure 8 、 Figure 9The positioning mechanism comprises a fixed plate 2, a driving piece 31, a threaded rod 32, a moving piece 33, a clamping piece 34, a lead screw 35, a positioning column 36, a worm wheel 37 and a worm 38. The fixed plate 2 is fixedly connected to the top of the workbench 1. Two movable cavities are formed in the fixed plate 2. The driving piece 31 is fixedly connected to one side of the fixed plate 2. The threaded rod 32 is fixedly connected to the output end of the driving piece 31. The threaded rod 32 is rotatably connected to the inside of the movable cavity.

The clamping piece 34 is slightly lower than the backplane glass, so that the backplane glass can be clamped and fixed without affecting the silk screen printing of the backplane glass.

[0043] In some embodiments, referring to Figure 10 、 Figure 11 、 Figure 12 The conveying mechanism comprises a hydraulic rod 41, a lifting frame 40, a driving shaft 42 and a conveying piece 43. The workbench 1 is internally provided with a groove 39. The hydraulic rod 41 is fixedly installed in the workbench 1 and located in the groove 39. The lifting frame 40 is fixedly connected to one end of the hydraulic rod 41 and internally fixedly connected with a double-shaft motor. The driving shaft 42 is fixedly connected to the output end of the double-shaft motor. The conveying piece 43 is movably connected to the side wall of the driving shaft 42. The inside of the fixed plate 2 is provided with a communication groove 30 matched with the conveying piece 43. When the backplane glass printing is completed, the lifting frame 40 is lifted by the hydraulic rod 41, so that the conveying piece 43 enters the communication groove 30 in the inside of the fixed plate 2, until the silk screen printed backplane glass is lifted. Then the driving shaft 42 is rotated by the double-shaft motor, so that the conveying piece 43 can convey the processed silk screen printed backplane glass. In this way, the silk screen printed pattern on the surface of the silk screen printed backplane glass can be prevented from being contacted during the conveying process, and the silk screen printing defects on the surface of the silk screen printed backplane glass can be reduced.

[0044] The working process and principle of this invention are as follows: The back glass is pushed onto the upper surface of the fixed plate 2 by the pushing device. The driving component 31 drives the threaded rod 32 to rotate, causing the moving component 33 to move to one side. The back glass is then clamped by the clamping component 34 at the top of the moving component 33. When the thickness of the back glass to be processed needs to be adjusted, the worm gear 38 is rotated by turning the knob, thereby rotating the worm wheel 37. When the worm wheel 37 rotates, it can drive the lead screw 35 to rotate through the internal thread groove, thereby adjusting the distance between the clamping component 34 and the moving component 33. This allows the clamping component 34 to be slightly lower than the back glass, which can clamp and fix the back glass without affecting the screen printing on the back glass. During printing, the second connecting component 27 falls down and the moving component... 13 will contact the upper surface of the screen 20. Since one side of the movable part 13 is curved, the movable part 13 tilts to the side, so that the curved surface contacts the upper surface of the screen 20. Then, the second servo motor 5 moves the mounting bracket 7 on one side of the movable plate 6, so that the glaze on the upper surface of the screen 20 is printed onto the back glass surface through the printing area 21 inside the screen 20. After that, the second connecting part 27 is raised, and the first connecting part 26 is lowered by the first pneumatic rod 8 so that the movable head 15 contacts the upper surface of the screen 20. By setting the movable head 15 at the discharge hole, when the movable head 15 contacts the upper surface of the screen 20, it will be pressed into the second mounting part 11, so that the glaze can pass through the movable head 15 and the second mounting part 11. The material flows out through the gap between the inner walls and is laid on top of the screen 20 by the movement of the mounting bracket 7. A spring is set between the movable head 15 and the mounting bracket 28. When the movable head 15 is disengaged from the upper surface of the screen 20, the spring will push the movable head 15 downward, so that the movable head 15 is located in the slot, blocking the bottom discharge hole of the second mounting part 11 and stopping the discharge. A spring is set on the side wall of the support rod 25 to give the first mounting part 10 a certain buffer space to prevent the first connecting part 26 from falling too low and crushing the glass. A silicone pad 24 is set on the outside of the printing area 21 inside the screen 20. When the screen 20 falls, the silicone pad 24 contacts the surface of the back glass, limiting the printing range and preventing the enamel from being squeezed out of the printing area during the printing process. 21. By setting a fixed frame 22 and a movable frame 23 on one side of the silicone pad 24, the silicone pad 24 is restricted, avoiding deformation of the silicone pad 24 due to excessive compression during the printing process. This can better ensure the printing quality of the back glass. After the back glass is printed, the lifting frame 40 is raised by the hydraulic rod 41, so that the conveyor 43 enters the connecting groove 30 inside the fixed plate 2 until the screen-printed back glass is raised. Then, the dual-axis motor drives the drive shaft 42 to rotate, so that the conveyor 43 can transport the processed screen-printed back glass. This can prevent the screen-printed pattern on the surface of the screen-printed back glass from coming into contact with it during the transport process, reducing the possibility of defects in the screen printing on the surface of the screen-printed back glass.
