Problems solved by technology

The above-mentioned process has the problems of incomplete cleaning and easy residual dust in the hole, which leads to PCB holes not being recognized or misjudged during hole position accuracy testing. In addition, the cleaning operation process includes multiple steps of manual loading and unloading and handling boards. Makes the cleaning process cumbersome, low product processing efficiency, long processing cycle, and high labor costs

Abstract

The invention discloses a reciprocating type dust removal device used after PCB drilling. The device comprises a reciprocating type dust removal mechanism, a drilling cleaning mechanism, a turnover plate cooling mechanism, a hole site precision testing mechanism and an automatic plate collection machine which are sequentially connected. The dust removal mechanism is connected with a dust removal feeding mechanical hand, and the hole site precision testing machine is connected with a testing feeding mechanical hand. Automatic dust removal and cleaning operation after drilling is achieved, the manual operation frequency of personnel in the cleaning and detection process is reduced, the processing efficiency is improved, the processing period is shortened, and the problem that a plate face isscraped in the manual repeated carrying process is solved. The reciprocating type dust removal mechanism can carry out dust removal treatment on plates repeatedly back and forth, the cleaning effectis more thorough, dust in holes can be effectively removed, and therefore follow-up hole site precision detection results are higher in accuracy. The invention further discloses a dust removal method.The dust removal method is wired type automatic dust removal method and is high in dust removal efficiency, good in cleaning effect and applicable to batch treatment on dilled plates.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board production, and relates to a post-drilling process, in particular to a reciprocating dust removal device and a dust removal method after PCB drilling. Background technique [0002] The production process of printed circuit board (PCB) includes multiple manufacturing links, and drilling is one of the key links, which can directly affect the overall quality of PCB. The purpose of drilling circuit boards in the process of making PCBs is: (1) A channel is created on the circuit board, allowing the subsequent process to complete the electrical performance between the upper, lower or middle circuit layers of the connection circuit board; (2) to ensure accurate and stable installation of circuit board components. According to the function of the hole, it can generally be divided into component holes, fastening holes, metallized holes, etc. [0003] At present, the PCB drilling process usua...
