Description
Technical Field
[0001] The utility model relates to the technical field of screen printing, in particular to a screen printing alignment device. Background Art
[0002] Screen printing refers to using a screen as a printing plate base and making a screen printing plate with graphics and text through a photosensitive plate-making method. Screen printing consists of five major elements: a screen printing plate, a squeegee, ink, a printing table, and a substrate. The printing is carried out based on the basic principle that the mesh holes in the graphic part of the screen printing plate can pass through the ink, while the mesh holes in the non-graphic part cannot. During printing, ink is poured at one end of the screen printing plate, and a certain pressure is applied to the ink part on the screen printing plate with a squeegee, while moving uniformly towards the other end of the screen printing plate. The ink is extruded from the mesh holes in the graphic part onto the substrate by the squeegee during the movement.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0031] Referring to Figure 2 , Figure 4 , Figure 5 , an embodiment provided by the present invention: A screen printing alignment device includes an operation table 1. A first electric push rod 2 is fixedly connected to the bottom of the operation table 1. The output end of the first electric push rod 2 is fixedly connected to a moving plate 3. Moving frames 4 are fixedly connected to the upper left and right sides of the moving plate 3, enabling the screen to be driven for position adjustment. A cylinder 5 is fixedly connected to the inside of the moving frame 4. The output end of the cylinder 5 is fixedly connected to a connecting plate 8. Two bumps 13 are slidably connected to the corresponding sides inside the connecting plate 8. Clamping plates 9 are fixedly connected to the corresponding sides of the bumps 13. An inner plate 12 is slidably connected to the inside of the clamping plate 9. Hinge frames 7 are rotatably connected to the front and rear sides of the moving frame 4 and the connecting plate 8. A first spring 6 is sleeved outside the output end of the cylinder 5 to clamp screens of different sizes. Moving grooves 14 are opened on the front and rear sides inside the inner plate 12 and on one side inside the clamping plate 9. A positioning component is fixedly connected to the inside of the moving groove 14. The positioning component is used for positioning the length of the fixture; Sliding grooves 10 are opened on the upper left and right sides inside the operation table 1. Scale sliding rods 11 are fixedly connected to the inside of the sliding grooves 10. The moving frame 4 is slidably connected to the inside of the sliding groove 10 and the outside of the scale sliding rod 11.
[0032] The positioning component includes a telescopic member 16. One end of the telescopic member 16 is fixedly connected to one side of the inner wall of the moving groove 14. The other end of the telescopic member 16 is fixedly connected to a moving head 15. A second spring 17 is sleeved outside the telescopic member 16. The moving head 15 is slidably connected to the inside of the moving groove 14. One end of the second spring 17 is fixedly connected to one side of the moving head 15. The other end of the second spring 17 is fixedly connected to one side of the inner wall of the moving groove 14. One end of the first spring 6 is fixedly connected to the corresponding side of the moving frame 4. The other end of the first spring 6 is fixedly connected to one side of the connecting plate 8.
[0033] By starting the cylinder 5, it drives the fixture to move through the connecting plate 8. At the same time, it drives the articulated frame 7 to stretch and pulls the first spring 6, generating a tensile force, which moves the fixture to a position where it can clamp the wire mesh, ensuring the stability of the fixture during movement and the firmness of its clamping. Place the wire mesh inside the fixture, which squeezes the clamping plate 9 to slide outside the inner plate 12. At the same time, it drives the bump 13 to slide inside the connecting plate 8, ensuring the smooth movement of the clamping plate 9 and squeezing the moving head 15 to move into the moving groove 14, and squeezing the telescopic member 16 and the second spring 17 to generate a resilience force. When the length adjustment of the fixture is completed, the moving head 15 is pushed by the resilience force of the telescopic member 16 and the second spring 17 to be inserted into the clamping plate 9 to fix its position. Start the first electric push rod 2 to drive the moving plate 3, so that the moving frame 4 slides outside the scale slide bar 11, moving the wire mesh to the accurate position, enabling it to automatically clamp and align wire meshes of different sizes without manual adjustment, greatly reducing the downtime and improving the production efficiency.
[0034] Refer to Figure 1 、 Figure 2 、 Figure 3 As shown in FIGS. 80, 81, 82, 83, 84, at the upper rear side of the operating table 1, a support frame 18 is fixedly connected. On the left and right sides of the front side inside the support frame 18, through grooves 19 are respectively opened. At the bottom sides inside the through grooves 19, second electric push rods 20 are fixedly connected. The output ends of the second electric push rods 20 are fixedly connected with a cross beam 21.

At the bottom of the inner wall of the dryer 23, a breathable mesh plate 26 is fixedly connected. Start the dryer 23, and the heat stored inside is dissipated through the breathable mesh plate 26 to dry the ink.
[0035] By starting the heating wire 24, it heats the air inside the dryer 23 and transfers its heat into the heat conducting plate 25, expanding the heat dissipation and storage. Start the second electric push rod 20 to drive the cross beam 21 to move downward, adjusting according to the height of the product to ensure drying the ink at the fastest speed. At the same time, start the trolley 22 to move it left and right to prevent some ink from not being dried, comprehensively drying the ink screen-printed on the product, preventing scratches or other accidents caused by the ink not being dry, which may affect the product quality.
[0036] Working principle: When the device needs to be used, start the cylinder 5 to drive the fixture to move through the connecting plate 8. At the same time, drive the articulated frame 7 to stretch and pull the first spring 6, so that the fixture is moved to a position where the wire mesh can be clamped. Place the wire mesh inside the fixture, so that it squeezes the clamping plate 9 to slide outside the inner plate 12, and squeezes the moving head 15 to move it inside the moving groove 14, and squeezes the telescopic member 16 and the second spring 17 to complete the length adjustment of the fixture. Start the first electric push rod 2 to drive the moving plate 3, so that the moving frame 4 slides outside the scale slide rod 11, and move the wire mesh to the accurate position, realizing automatic clamping and alignment of wire meshes of different sizes without manual adjustment, greatly reducing the downtime and improving the production efficiency;
[0037] Start the heating wire 24 to heat the air inside the dryer 23, and transfer its heat to the heat conduction plate 25. Start the second electric push rod 20 to drive the cross beam 21 to move down, and at the same time start the trolley 22 to move it left and right, realizing comprehensive drying of the ink printed on the product, preventing accidental scratching or other accidents caused by the ink not being dry, which affects the product quality.
