Dispensing circulation standing circulation process of PCBA board

Abstract

The invention relates to a dispensing circulation standing circulation process of a PCBA board, and belongs to the technical field of production of electronic components. The process is characterized by comprising the following steps that the PCBA board subjected to dispensing is placed on a working surface capable of realizing circulating parallel displacement; the working surface capable of realizing parallel displacement enters a drying box from an inlet of one drying box body; and a programmable controller controls starting and stopping of a displacement motor through safety optical grating signal feedback of sensors arranged at an inlet and an outlet of the drying box, the passing time of the PCBA board in the drying box body is 20-30 minutes, and then the dried PCBA board is taken out from the outlet. A plurality of fans for drying are uniformly arranged at two side plates of the drying box body; and the working surface capable of achieving circulating parallel displacement is a movable flat plate mechanism driven by a chain wheel. The process is simple and convenient to operate, the mistake and fool phenomena caused by human errors are reduced, the process efficiency and effect are improved, and mistake and fool can be effectively prevented.

Description

Technical field: [0001] The present invention relates to a kind of glue dispensing circulation static turnover process of PCBA board, which belongs to the technical field of production of electronic components, especially the technical field of component glue dispensing process of PCBA board Background technique: [0002] In the production process of electronic products, the production process of circuit boards is a very important link. In the process of PCBA board processing, in order to strengthen the reliability verification of the drop test of the PCBA board, the components and tin points of the PCBA board must be reinforced by dispensing glue. If the PCBA board is directly processed in the next step after dispensing glue, and the surface layer of the glue is not air-dried, the glue on the employee's fingers will cause contamination of the shell during operation, which will be difficult to handle later, and rework will cause economic losses. [0003] In order to solve t...

Problems solved by technology

[0004] Because this method judges the turnover manually, it cannot guarantee whether the turnover time meets the static requirements, and the existing turnover car is divided into multi-layer PCBA plate fixtures, it is difficult to judge the order of the previous process placement, and the turnover time Employees are asked to judge for themselves whether they have been placed

Therefore, this method of operation requires strict management to ensure the quality of the workmanship, which is neither intelligent nor often erroneous.
