[0002] The silk-screen base is a tool used to fix objects during silk-screen processing. Silk-screen printing on curved glass is a technology for printing on curved glass. It is mainly used for display screens or exterior decoration of products such as mobile phones, tablet computers, and car dashboards. Silk-screen printing technology for curved glass needs to be able to print accurately on the curved surface to ensure the continuity and consistency of patterns and text on the curved surface. Since curved glass screens are usually used in high-end electronic products, extremely high printing accuracy is required to achieve the dual effects of beauty and practicality. The patterns and text printed on the curved glass need to have good wear resistance and corrosion resistance to ensure the long-term service life of the product.

Detailed Embodiment

[0029] The present utility model will be further described below by way of examples, but the present utility model is not limited to the scope of the described examples.

[0030] As Figures 1-6 shown, the screen printing base for 3D curved glass screens includes:

[0031] Base 1, a border 2 is provided at the top of the base 1, a socket 6 is provided at the edge of the border 2, and an opening 7 corresponding to the socket 6 is provided at the edge of the base 1. A pressure rod 11 is provided inside both the socket 6 and the opening 7. The bottom of the base 1 is fixedly connected to a leg 9. The pressure rod 11 is located between the legs 9, and a lifting mechanism is connected to the bottom end of the pressure rod 11;

[0032] Base 15, the base 15 is fixedly connected to the bottom of the base 1. A negative pressure pipe 18 is fixedly connected to the bottom of the base 15. A translation mechanism is provided inside the negative pressure pipe 18, and the translation mechanism is in transmission connection with the lifting mechanism. The negative pressure pipe 18 is connected through the base 15 and is located at the bottom of the base 1. A number of uniformly distributed fine holes 17 are provided inside the base 1.

[0033] In this technical solution, the border 2 is a square structure. The border 2 is attached to the top edge of the base 1. Grooves for placing a curved glass screen are provided on both the border 2 and the base 1 and are matched with each other. The cooperation of the border 2 and the base 1 can realize the placement of the curved glass screen, so that the formed groove can be adapted to the curved glass screen.

[0034] In this technical solution, both ends of the border 2 are fixedly connected to a convex edge 3. The convex edge 3 is fixedly connected to the top of the base 1 by a screw 4. Two symmetrically distributed sockets 6 are provided at the other two ends of the border 2. The screw 4 on the convex edge 3 realizes the fixation of the convex edge 3 and the border 2, and can play a positioning and assembling function.

[0035] In this technical solution, the cross-section of the pressure rod 11 is an L-shaped structure. The top end of the pressure rod 11 extends into the border 2. The bottom of the pressure rod 11 is fixedly connected to a connecting shaft 10. Both ends of the connecting shaft 10 are slidably connected inside the long holes provided on the legs 9. When the pressure rod 11 moves, it can drive the connecting shaft 10 to move vertically, so that the connecting shaft 10 moves in the long holes between the legs 9.

[0036] In this technical solution, the outer wall of the base 1 is fixedly connected to a limiting block 8. The limiting block 8 is located inside the opening 7. A guiding block 12 is fixedly connected to the surface of the pressure rod 11 located inside the opening 7. The guiding block 12 and the limiting block 8 are provided with corresponding inclined surfaces and are in contact with each other. The pressure rod 11 is attached to the side wall of the base 1. When the pressure rod 11 moves downward, the guiding block 12 on the pressure rod 11 contacts the limiting block 8, and forces the pressure rod 11 to be attached to the surface of the base 1. At this time, the guiding block 12 moves into the opening 7 inside the limiting block 8, realizing the position limitation of the pressure rod 11. When the pressure rod 11 moves upward, the guiding block 12 is separated from the limiting block 8. At this time, the bent elastic piece 16 resets, so that it pushes the pressure rod 11 to rotate outward, facilitating the removal of the glass screen after silk printing.

[0037] In this technical solution, a shrapnel 16 with a bent structure is fixedly connected to the outside of the base 15. The shrapnel 16 contacts the surface of the pressure rod 11 and can contact the pressure rod 11. When the guide block 12 moves into the limit block 8, the shrapnel 16 is compressed at this time. When the guide block 12 separates from the limit block 8, a gap is formed between the limit block 8 and the pressure rod 11 at this time. The elasticity of the shrapnel 16 can push the pressure rod 11 to rotate, and the pressure rod 11 rotates around the connecting shaft 10 inside the long hole of the leg 9.

[0038] In this technical solution, the lifting mechanism includes a cross bar 13 and a vertical bar 14. The cross bar 13 is located between the leg 9 and the pressure rod 11. The end of the cross bar 13 is rotatably connected to the connecting shaft 10, and the middle of the cross bar 13 is fixedly connected to the vertical bar 14. The cross bar 13 is used for the connection of the connecting shaft 10, so that when the cross bar 13 and the vertical bar 14 move upward, the pressure rod 11 can be driven to move synchronously.

[0039] In this technical solution, the translation mechanism includes a fixed tube 19. The fixed tube 19 is fixedly connected to the negative pressure tube 18. The inner diameter of the negative pressure tube 18 is larger than the inner diameter of the fixed tube 19. The negative pressure tube 18 is an L-shaped structure and is fixedly connected to the extension tube 20. The guide rod 21 is inserted through the inside of the extension tube 20. The guide rod 21 is located inside the negative pressure tube 18 and is fixedly connected to the plug block 22. The diameter of the plug block 22 is the same as the diameter of the negative pressure tube 18. When the negative pressure device is externally connected to the negative pressure tube 18 and the curved glass screen is placed inside the base 1, the air in the negative pressure tube 18 is exhausted. The formed negative pressure first drives the plug block 22 to move into the fixed block. When the plug block 22 drives the guide rod 21 to move, the connecting rod 24 is driven to rotate. When the connecting rod 24 rotates to a position tending to be vertical, it drives the cross bar 13 and the vertical bar 14 to move downward, and then presses down the pressure rod 11 and presses the edge of the curved glass screen. When the plug block 22 moves into the fixed tube 19, the pressure rod 11 moves in place at this time, and at the same time, the air flow inside the guide groove 5 and the base 15 is exhausted, so that a negative pressure is formed at the bottom of the glass screen in the pressed state, thereby realizing further adsorption and fixation to ensure the stability of the glass screen in the base.

[0040] In this technical solution, a spring 23 is fixedly connected inside the extension tube 20. The spring 23 is sleeved on the surface of the guide rod 21. The guide rod 21 located outside the extension tube 20 is connected to the middle of the vertical bar 14 through the connecting rod 24. After the operation is completed, the gas is filled into the negative pressure tube 18. The formed positive pressure pushes the plug block 22 to move into the extension tube 20 and compresses the spring 23. At this time, the connecting rod 24 rotates to a position tending to be horizontal and pulls the pressure rod 11 away from the curved screen. At the same time, the negative pressure tube 18 is communicated to form a positive pressure inside the guide groove 5, thereby realizing the removal of the glass screen. When the gas filling stops, the elasticity of the spring 23 pushes the plug block 22 to move into the negative pressure tube 18, which is convenient for driving the plug block 22 to move when the negative pressure is formed subsequently.

[0041] In the present technical solution, the base 15 is located below the fine holes 17 and communicates with the fine holes 17. A number of uniformly distributed guiding grooves 5 are formed at the bottom of the base 1. Each of the guiding grooves 5 communicates with the fine holes 17. When negative pressure is formed in the negative pressure tube 18, the gas inside the guiding grooves 5 and the base 15 can be discharged, realizing the adsorption function, and at the same time ensuring stable adsorption at each position of the curved screen, improving the stability performance.

No matter what changes are made in its shape or structure, they all fall within the protection scope of the present utility model. The protection scope of the present utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present utility model, but these changes and modifications all fall within the protection scope of the present utility model.
