Problems solved by technology

The existing PCB board silk screen printing process usually performs plug hole printing first, and then prints the front and back sides of the PCB board. Among them, plug hole printing and front and back side printing need to be completed on different screen printing machines, that is, the PCB board silk screen printing process requires at least It is completed on three pieces of equipment, and every time a process is completed, the PCB board needs to be sent to the next process manually. The production efficiency is low, the operation is time-consuming and laborious, and the labor cost is high, which is not conducive to improving production efficiency.

Embodiment 1

[0025] see figure 2 , Embodiment 1 specifically includes the following steps:

[0026] In step a, the PCB board to be printed is fixed on the workbench through a positioning template, a number of positioning bumps are set on the positioning template, and positioning holes corresponding to the positioning bumps are set on the PCB;

[0027] Step b1, the workbench drives the PCB board to be printed to move horizontally to the first silk screen printing station for plug hole printing; the first silk screen printing station includes the first silk screen printing station and the first screen printing screen installed on the first screen printing station, the first silk screen printing station Screen printing screen is a screen printing screen used for plug hole printing. When printing at the first silk screen station, the first screen screen and the PCB board to be printed are positioned correspondingly through the center point.

[0028] In step b2, after the plug hole printing ...

Embodiment 2

[0031] see image 3 , Embodiment 2 specifically includes the following steps:

[0032] In step a, the PCB board to be printed is fixed on the workbench through a positioning template, a number of positioning bumps are set on the positioning template, and positioning holes corresponding to the positioning bumps are set on the PCB;

[0033] In step b1, the workbench drives the PCB board to be printed to move horizontally to the first screen printing station for plug hole printing; when printing at the first screen printing station, the first screen screen and the PCB board to be printed are positioned correspondingly through the center point.

[0034] In step b2, after the plug hole printing is completed, the workbench drives the PCB board to be printed to move horizontally to the second screen printing station for printing on the board surface. When printing at the second screen printing station, the second screen printing screen and the PCB board to be printed are also positi...

Abstract

The invention discloses a PCB screen printing process capable of realizing more than two times of printing by one-time location. The PCB screen printing process comprises the following steps: firstlylocating a to-be-printed PCB on a movable worktable; subsequently driving the to-be-printed PCB to horizontally move to different screen printing stations in sequence by virtue of the worktable; and performing at least two times of screen printing operation. According to the screen printing process, the to-be-printed PCB can be driven to move horizontally by virtue of the movable worktable, thus the to-be-printed PCB can sequentially move to different screen printing stations so as to be subjected to at least two times of screen printing operation, more than two times of printing is realized by one-time location, multi-time location operation is not needed, manual operation is reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of PCB silk screen printing, and more specifically, relates to a silk screen printing process for realizing more than two printings at one time of PCB positioning. Background technique [0002] The principle of screen printing is: when printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the graphic part to form the same graphic as the original. This screen printing technology can be applied to PCB board printing . The existing PCB board silk screen printing process usually performs plug hole printing first, and then prints the front and back sides of the PCB board. Among them, plug hole printing and front and back side printing need to be completed on different screen printing machines, that is, the PCB board silk screen printing process requires at least It is completed on three pieces of equipment, and every time a process is completed, the PCB board...
