Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a screen printing machine for electronic glass production. Background Technology

[0002] The electronic glass screen printing process involves automatically positioning the electronic glass to a preset position on the screen printing platform using vacuum adsorption and positioning columns. Then, the screen moves down and hovers above the electronic glass to be screen printed. Finally, the ink pre-poured into the screen is squeezed through the mesh of the pattern area onto the electronic glass product by pressing down the mesh with adhesive.

[0003] In the document CN217293873U, the electronic glass to be screen-printed is placed on the platform 100 at the adsorption gas tank 110 and adsorbed. When the electronic glass is fixed by adsorption gas tank, the adsorption force is uneven due to local blockage or unstable air pressure in the adsorption gas tank. The adsorption effect of the adsorption gas tank on the electronic glass is poor, which causes the glass to shift during the screen printing process, thereby reducing the screen printing effect of the glass. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the adsorption gas groove has a poor adsorption effect on electronic glass, resulting in glass displacement during screen printing and thus reducing the screen printing effect. Therefore, this invention proposes a screen printing machine for electronic glass production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a screen printing machine for electronic glass production, including a support plate, a support platform fixedly connected to the upper end of the support plate, a base frame fixedly connected to the bottom end of the support plate, a limit frame fixedly connected to the upper end of the support platform, a plurality of through holes evenly spaced along the length direction of the support platform, a spring fixedly connected to the bottom end of the support plate, a connecting plate fixedly connected to one end of the spring, a horizontal tube fixedly connected to one side of the connecting plate, a plurality of guide tubes evenly spaced along the length direction of the upper end of the horizontal tube, a suction cup connected to one end of each guide tube, each suction cup being located in a through hole, and the upper end of each suction cup extending out of the through hole.

[0007] Preferably, the base frame includes a base plate, and a plurality of support columns are fixedly connected to the upper end of the base plate, with one end of each support column fixedly connected to the support plate.

[0008] Preferably, an anti-wear pad is fixedly connected to the bottom end of the base plate.

[0009] Preferably, a connecting pipe is connected to the horizontal pipe, and a pressure detector is connected to the connecting pipe.

[0010] Preferably, a guide plate is fixedly connected to the horizontal tube, a guide seat is fixedly connected to the bottom end of the support plate, and one end of the guide plate is slidably inserted into the guide seat.

[0011] Preferably, a pushing mechanism is connected to the base plate. The pushing mechanism includes an electric telescopic rod, which is fixedly connected to the base plate. A movable frame is fixedly connected to the telescopic end of the electric telescopic rod. Push plates are fixedly connected to both sides of the movable frame. Movable holes are opened on both sides of the support platform. Each movable hole passes through the support plate. One end of each push plate is slidably inserted into the corresponding movable hole. An anti-slip pad is fixedly connected to the upper end of each push plate.

[0012] Preferably, the movable frame and the push plate are an integral structure.

[0013] Preferably, the upper surface of the anti-slip pad is lower than the upper surface of the movable hole.

[0014] The screen printing machine for electronic glass production proposed in this utility model has the following advantages:

[0015] The electronic glass on the support platform squeezes the suction cup, which in turn moves the guide tube downwards. The guide tube then moves the horizontal tube downwards, which in turn moves the connecting plate downwards. As the connecting plate moves downwards, it stretches the spring. The spring, due to its stretching, generates elastic force and pulls the connecting plate upwards, thus ensuring that the suction cup and the bottom of the electronic glass are in tight contact. This ensures that the suction cup and the glass surface are in close contact, enhancing the adsorption stability and preventing the glass from moving during the screen printing process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A screen printing machine for electronic glass production includes a support plate 1, a screen printing mechanism 2 fixedly connected to the upper end of the support plate 1, a support platform 3 fixedly connected to the upper end of the support plate 1, a base frame 4 fixedly connected to the bottom end of the support plate 1, a limit frame 5 fixedly connected to the upper end of the support platform 3, a plurality of through holes 6 evenly spaced along the length direction on the support platform 3, each through hole 6 passing through the support plate 1, a spring 7 fixedly connected to the bottom end of the support plate 1, a connecting plate 8 fixedly connected to one end of the spring 7, and a connecting plate 8... A horizontal tube 9 is fixedly connected to the side. Several conduits 10 are connected at equal intervals along the length of the upper end of the horizontal tube 9. One end of each conduit 10 is connected to a suction cup 11. Each suction cup 11 is located in a through hole 6. The upper end of each suction cup 11 extends out of the through hole 6. A connecting tube 12 is connected to the horizontal tube 9. A pressure detector 13 is connected to the connecting tube 12. A guide plate 15 is fixedly connected to the horizontal tube 9. A guide seat 14 is fixedly connected to the bottom end of the support plate 1. One end of the guide plate 15 is slidably inserted into the guide seat 14.

[0023] Work process:

[0024] The electronic glass is placed on the support platform 3, and the limiting frame 5 limits the electronic glass to ensure that its position on the support platform 3 is accurate and to avoid deviation or slippage, thereby improving the accuracy of processing or inspection. Since the upper end of the suction cup 11 extends out of the through hole 6, the electronic glass placed on the support platform 3 will squeeze the suction cup 11. The suction cup 11 drives the guide tube 10 to move downward, and the guide tube 10 further drives the horizontal tube 9 to move downward. The horizontal tube 9 drives the guide plate 15 to move, and the guide plate 15 slides on the guide seat 14. With the cooperation of the guide plate 15 and the guide seat 14, the horizontal tube 9 can move smoothly.

[0025] At the same time, the horizontal tube 9 also drives the connecting plate 8 to move downward. After the connecting plate 8 moves downward, it stretches the spring 7. The spring 7 generates elastic force due to the stretching and pulls the connecting plate 8 upward, so that the suction cup 11 is tightly pressed and contacted with the bottom of the electronic glass. The suction pressure is adaptively adjusted by the elastic force of the spring 7 to ensure that the suction cup 11 is tightly attached to the glass surface, enhance the suction stability, and prevent the glass from moving during the screen printing process.

[0026] An external air extraction mechanism extracts gas from the horizontal tube 9 through the connecting pipe 12. The horizontal tube 9 then extracts gas from the suction cup 11 through the conduit 10, creating a negative pressure inside the suction cup 11, which adsorbs and fixes the electronic glass. The pressure detector 13 monitors the negative pressure state inside the suction cup 11 in real time to ensure that the adsorption force is always within a safe and effective range, thereby improving process reliability and product quality.

[0027] Example 2: Refer to Figure 2 As another preferred embodiment of the present invention, the difference from embodiment 1 is that the base frame 4 includes a base plate 41, and a plurality of support columns 42 are fixedly connected to the upper end of the base plate 41. One end of each support column 42 is fixedly connected to the support plate 1. An anti-wear pad 43 is fixedly connected to the bottom end of the base plate 41. The anti-wear pad 43 protects the bottom end of the base plate 41 and prevents the bottom end of the base plate 41 from being worn.

[0028] Example 3: After the electronic glass screen printing is completed, it is inconvenient to remove the glass because it is attached to the support platform 3. (Refer to...) Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a pushing mechanism 16 is connected to the base plate 41. The pushing mechanism 16 includes an electric telescopic rod 161, which is fixedly connected to the base plate 41. A movable frame 162 is fixedly connected to the telescopic end of the electric telescopic rod 161. Push plates 163 are fixedly connected to both sides of the movable frame 162. The movable frame 162 and the push plates 163 are an integral structure. Movable holes 164 are opened on both sides of the support platform 3. Each movable hole 164 passes through the support plate 1. One end of each push plate 163 is slidably inserted into the corresponding movable hole 164. An anti-slip pad 165 is fixedly connected to the upper end of each push plate 163. The upper end surface of the anti-slip pad 165 is lower than the upper end surface of the movable hole 164.

[0029] After the screen printing is completed, the electric telescopic rod 161 is activated, which drives the movable frame 162 to move upward by a set distance. The movable frame 162 drives the push plate 163 to move. The push plate 163 pushes the electronic glass through the anti-slip pad 165, so that the electronic glass is separated from the support platform 3, making it easy to remove the electronic glass. After the glass is removed, the electric telescopic rod 161 drives the movable frame 162 to move downward to reset. The movable frame 162 drives the push plate 163 to move and reset.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
