The working principle of an automatic coater for screen printing is the same, but its performance varies according to different models and different manufacturers. The screen coater is equipped with a device capable of clamping the vertical frame of the screen frame. The front and back of the screen area is a horizontal coating mechanism consisting of a coating box and mechanical or pneumatic components that control the angle and pressure of the coating box.
Both ends of the coating mechanism are installed on the vertical support arm of the coating machine, and the coating mechanism moves up and down through the transmission of belts, chains or cables to coat along the surface of the wire mesh. The transmission mechanism is connected with a servo or variable frequency motor to make it run stably and precisely control the position of the coating mechanism.
Before coating, load clean, stretched stencils from the front of the coater, and some models can also be loaded from the side. Sideloading is more common in model frames designed for larger sizes because the frame is large and heavy, and sideloading reduces the amount of lift and movement. When the automatic screen coater is running in-line with other automatic screen processing equipment such as cleaning equipment, regeneration equipment, drying equipment and developing machines, it is more convenient to load the printing plate from the side.
Regardless of how the screen is mounted, once the screen is in the correct position, the pneumatic or mechanical clamping device will close to lock the screen. To make operation even more convenient, many models have pedals to control the movement of the plate clamps, so that the operator can free both hands to control the screen. After installing the stencil, pour the corresponding photosensitive emulsion into the automatic coating machine to start coating. Depending on the function of the control system and the equipment, the equipment can coat both sides of the screen at the same time.
