Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a screen printing auxiliary exposure plate device. Background Technology

[0002] A screen printing machine is a device used for screen printing on various materials. Its working principle involves the relative movement of the screen printing plate and the squeegee, which forces ink through the mesh onto the substrate to form the desired pattern. Screen printing machines are widely used for printing on textiles, paper, plastics, metals, and many other materials.

[0003] The working principle of a screen printing machine can be summarized in the following steps: 1. Power transmission mechanism: The squeegee, in its movement, squeezes the ink and the screen printing plate, forming an impression line between the screen printing plate and the substrate. 2. Ink leakage through the mesh: Under the pressure of the squeegee, the ink leaks through the mesh from the moving impression line onto the substrate. 3. Screen rebound: Under the rebound force, the screen promptly returns to its original position and disengages from the substrate to prevent smudging of the print. 4. Completion of printing cycle: After completing unidirectional printing, the squeegee and the screen printing plate detach from the substrate, and simultaneously return to the substrate for ink return, thus completing one printing cycle.

[0004] Plate exposure, also known as exposure, refers to the process of transferring images and text from a film, tracing paper, or other highly transparent carrier onto a printing plate coated with a photosensitive material, such as a screen or PS plate, through exposure.

[0005] Existing printing equipment faces increasingly complex printing processes and more and more print heads. On-machine plate matching and adjustment waste a lot of manpower and time. Even if customers purchase intelligent machines that do not require plate matching, they cannot achieve the expected results. Utility Model Content

[0034] Reference Figures 1-6 A screen printing auxiliary exposure device includes a frame 1, a front crossbeam 100 and a rear crossbeam 101 mounted on the frame 1. The rear crossbeam 101 is higher than the front crossbeam 100. Sliding components 2 are installed on both the front and rear crossbeams 101. Screen hanging devices 4 for placing screen printing plates 3 are installed at both ends of the front crossbeam 100. A cross alignment light 5 is installed on the top of the front crossbeam 100, which includes a light box 500, multiple light sources 501 installed in the light box 500, and multiple cross coordinate positioning lines 502 pasted on the light box 500. The alignment light 5, also called a plate alignment light, can slide along the length of the front crossbeam 100 via the sliding components 2. The crosshair alignment light 5, which moves back and forth, is an optical device used for precise positioning. Widely used in textiles, clothing, woodworking, and tire manufacturing, it emits a cross-shaped laser beam to help operators achieve precise alignment during cutting, sewing, and printing processes, thereby improving work efficiency and product quality. An industrial camera 6 is mounted on the rear crossbeam 101, above the alignment light 5. The industrial camera 6 can move back and forth along the length of the rear crossbeam 101 via a sliding component 2. It is a camera device specifically designed for industrial applications, widely used in automated production lines, machine vision systems, and quality control.

A display 7 is mounted below the rear crossbeam 101, used by the industrial camera 6 to transmit high-quality image and video data.

[0035] In use, turn on the power, start the monitor 7 and industrial camera 6, fix the screen 3 between the two screen hanging devices 4, place the film on the corresponding area of ​​the screen 3, and then adjust and lock the alignment light 5 to the corresponding position by moving it left and right. Adjust the aperture, focus, brightness, etc. of the industrial camera 6, and observe the coordinate position on the monitor 7. Adjust the position of the film so that the cross lines on the film coincide with the cross lines on the alignment light. Then, use glue to stick the film in place to prevent it from shifting. Remove the aligned screen 3, attach the new screen 3, and adjust the film position so that the crosshairs on the film align with the crosshairs on the alignment light 5. Secure the film, remove screen 3, and place the new screen 3 again. Repeat the above steps until all required screen 3s are aligned, thus achieving a uniform relative position of the film pattern on each screen 3. Then, expose each screen 3 individually on the exposure machine. With this application, the screen 3 can be pre-calibrated, ensuring a basically uniform printed pattern. The screen 3 can then be directly installed on the printing machine, the printing head position reset, and the screen 3 is aligned, allowing for immediate printing. This achieves the effect of no need for machine adjustments, saving time and improving work efficiency, eliminating the need to waste a lot of manpower and time on machine adjustments and alignment.

[0036] In some embodiments, the sliding assembly 2 includes a linear guide rail 200, a U-shaped slider 201 mounted on the linear guide rail 200, and a sliding seat 202 mounted on the slider 201. The sliding seat 202 can reciprocate along the linear guide rail 200 via the slider 201. One linear guide rail 200 is mounted at the bottom of the front crossbeam 100, and the other linear guide rail 200 is mounted at the top of the rear crossbeam 101. The sliding assembly 2 has a simple structure, is easy to operate, and occupies little space.

[0037] In some embodiments, a locking member 203 is also included, which is installed on the sliding seat 202 for locking or loosening the sliding seat 202. The locking member 203 may be a screw, bolt, etc. During the tightening process, the locking member 203 abuts against the linear guide 200, the front crossbeam 100 or the rear crossbeam 101, thereby achieving locking and limiting. The structure is simple and convenient.

[0038] In some embodiments, the netting device 4 includes a base plate 400 and netting pins 401 vertically mounted on the base plate 400, which are easy to install and remove; there is at least one netting pin 401, but in order to improve the stability of the fixed netting 3, there may be two or more pins arranged in a regular manner.
