Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a high-precision printing module. Background Art

[0002] Screen printing is a type of stencil printing, considered one of the four major printing methods along with lithography, letterpress, and gravure. Stencil printing includes stencil printing, perforated stencil printing, inkjet printing, and screen printing. The principle of stencil printing is that ink is passed through a printing plate, a paper film, or other substrate. During printing, pressure is applied to transfer the ink through the stencil's perforations to a substrate, such as paper or ceramic, creating an image or text. A scraper then presses the ink through the mesh in the image onto the substrate, creating a graphic that resembles the original. However, traditional screen printing is typically performed manually by operators, which is time-consuming and labor-intensive, resulting in low efficiency, high labor costs, and limited precision, making it unsuitable for high-volume production.

[0043] During operation, the sheet material is first placed on the workbench 1, and the screen clamping mechanism 2 is used to clamp and fix the position of the screen material so that the screen material is located above the sheet material. The screen clamping mechanism 2 is driven by the first driver 3 to move along the length direction of the workbench 1, and the screen material is moved left and right to effectively adjust the position of the screen material relative to the sheet material. The scraper mechanism 4 is driven by the second driver 5 to move along the length direction of the workbench 1, and the scraper mechanism 4 is located above the screen clamping mechanism 2, so that the second driver 5 drives the scraper mechanism 4 to move back and forth on the screen material. The scraper mechanism 4 squeezes and scrapes the ink applied to the screen material in advance, so that the ink passes through the mesh of the screen material and is coated and transferred to the sheet material, thereby completing the screen printing work. The whole process is automated, which greatly saves labor costs and improves production efficiency. The utility model has a compact structure and a reasonable design, realizes automated screen printing work, improves printing efficiency and work accuracy, and is convenient for meeting the needs of mass production.

Specifically, during operation, the first driving assembly 23 drives the adjusting assembly 22 to move horizontally along the length direction of the machine base 21, thereby adjusting the adjusting assembly 22 to a suitable position, and the first clamping groove 222 and the second clamping groove 223 are close to or away from each other along the length direction of the base 221. When fixed, the mesh plate is placed between the first clamping groove 222 and the second clamping groove 223, and the outer peripheral walls of the mesh plate are engaged and fixed with the inner walls of the first clamping groove 222 and the inner walls of the second clamping groove 223. By rotating the first screw 226 clockwise and making the first screw 226 threadedly connected to the first nut 224, the first clamping block 228 is driven to move downward, further prompting the first clamping block 228 to be clamped and fixed on the top of the mesh plate, and by rotating the second screw 227 clockwise and making the second The second screw 227 is threadedly connected to the second nut 225, thereby driving the second clamping block 229 downward, further causing the second clamping block 229 to clamp and fix the top of the stencil, thereby fixing the stencil in multiple directions, reducing the possibility of stencil position deviation and improving printing quality. When the stencil needs to be replaced, the first screw 226 is rotated counterclockwise and the first screw 226 is moved away from the first nut 224, thereby driving the first clamping block 228 upward and away from the stencil. The second screw 227 is rotated counterclockwise and the second screw 227 is moved away from the second nut 225, thereby driving the second clamping block 229 upward and away from the stencil, thereby facilitating the removal of the stencil and improving practicality and connection reliability. The ion wind bar 24 is arranged on the back of the machine base 21. When in operation, the ion wind bar 24 generates positively and negatively charged air masses, which effectively neutralize the charge on the stencil surface, achieving the purpose of eliminating static electricity.

[0045] In this embodiment, the first clamping groove 222 and the second clamping groove 223 are both C-shaped. The first clamping groove 222 is provided with a first slider 2210, and the second clamping groove 223 is provided with a second slider 2211.

Specifically, the limit blocks 2213 are installed at both ends of the base 221. When the first clamping groove 222 and the second clamping groove 223 slide on the base 221, the limit blocks 2213 block and interfere with the first slider 2210 and the second slider 2211, thereby providing a good blocking and limiting function, effectively preventing the first slider 2210 and the second slider 2211 from accidentally falling off the guide rail 2212 due to excessive sliding, thereby improving work safety.
