Existing screen printing alignment devices cannot guarantee that the pattern on the screen frame is aligned with the printed item after adjustment, resulting in poor printing quality.
The system employs components such as a screen mounting frame, an L-shaped support frame, an adjusting slider, an alignment laser light, and an adjusting threaded rod. The alignment laser light irradiates the light beam and aligns it with the printed workpiece. The adjustment knob and threaded rod drive the support slider to move, achieving precise positioning and fixation of the screen frame.
It improves the accuracy and stability of screen printing alignment and enhances the alignment effect between the screen frame and the printed item.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen printing alignment technology, and more specifically, to a screen printing alignment device. Background Technology
[0002] Screen printing refers to the process of creating a screen printing plate with images and text using a photosensitive method. Screen printing consists of five main elements: the screen printing plate, the squeegee, the ink, the printing table, and the substrate. It utilizes the basic principle that ink can pass through the mesh openings of the screen printing plate where the image areas are open, but not where. During printing, ink is poured into one end of the screen printing plate, and the squeegee applies pressure to the ink areas. To ensure printing quality, during registration printing, the printing frame needs frequent repositioning if misalignment occurs, as illustrated by patent CN216733454U. A screen printing alignment device is disclosed. The device is installed at the corresponding printing position on the printing machine through a positioning plate, positioning holes and bolts. The device's circuit is externally connected to the control system. The screen frame to be printed is placed into the placement groove, so that the two side walls of the screen frame can make real-time contact and limit the movement with the inner wall of the placement groove. The motor is started manually to run in real time. The motor drives the screw to rotate and the thread drives the drive block to move to the printing position. The position is sensed in real time by a sensor and the signal is transmitted to the control system for real-time analysis and judgment. Then, the cylinder can be controlled to drive the telescopic rod to extend and retract to push the push plate to make local fine adjustment of the position of the screen frame.
[0003] When the above-mentioned device is in use, the control cylinder drives the telescopic rod to extend and retract, pushing the push plate to make local fine adjustments to the position of the screen frame, replacing manual adjustment and alignment, making the alignment more accurate and efficient. However, after adjusting the screen frame, it cannot guarantee that the pattern of the screen frame is aligned with the position of the printed item, resulting in poor screen printing alignment effect.

Then, the screen frame can be placed on top of the L-shaped screen support block, and the pattern position of the screen frame can be placed between the two support sliders. The screen frame can then be fixed and stabilized, which can effectively improve the alignment effect during screen printing. Attached Figure Description
