Supports and printing machines

Abstract

The invention provides a supporting piece. The supporting piece is used for fixing a screen frame of a printing machine. The supporting piece comprises a supporting component and a connecting component, wherein the supporting component is located below the screen frame and used for supporting the screen frame; and the connecting component is located on one side of the supporting component and used for making the supporting component be connected to a screen frame fixing device of the printing machine. Correspondingly, the invention provides the printing machine. By the adoption of the technical scheme, the balance and stability of the screen frame are effectively guaranteed, and the problem of water seepage, caused by damage, of a screen printing plate in the use process of the screen frame is solved; and in addition, the effect that normal production can be conducted under the normal screen tensioning condition is guaranteed, safety protection of the printing machine is achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circuit board printing, and more specifically, to a supporting member and a printing machine table. Background technique [0002] As the printed circuit industry matures and develops, the circuit board production process continues to develop and improve. In the process of circuit board tooling and screen frame production, the traditional cleaning mode of wiping and brushing has developed into a soaking cleaning mode. This production process not only solves the problems of labor-intensive and messy working environment, but also greatly reduces the consumption of water and chemicals, reduces production costs, has less environmental pollution, and improves the service life and production efficiency of the screen frame. The traditional screen frame corner splicing is in the form of electric welding or glue filling, which can seal the seams relatively firmly, but corner cracks are still inevitable. [0003] T...

AI Technical Summary

Problems solved by technology

Since the screen frame is hollow, during the process of carrying and placing the screen frame, its corners are prone to damage, exposing the gaps of the original splicing, and cracks appear, causing water to enter the screen frame when the screen is cleaned and soaked.

During the installation and production process of the screen frame, the water in the screen frame drips onto the machine or the circuit board surface, which affects the safety and quality of on-site production. Considering the safety and quality of the cracked screen frame, the site needs to be checked before production. The screen frames are inspected one by one. Generally, only one screen frame for text printing is prepared for one production part number. If the screen frame is abnormal, it needs to be repaired temporarily, which requires high personnel operation and will affect production efficiency.

[0004] The existing text printing machine is fixed in the middle on both sides. During production, the screen frame moves horizontally and vertically continuously. The balance is not particularly stable due to the influence of gravity, and the external operation touching the screen frame is likely to cause its imbalance. , affect the printing quality of the circuit board, and even cause the mesh to break in severe cases
