Problems solved by technology
[0003] In the prior art, during the transportation and storage process after production, the surface of the PCB board will accumulate dust, which has a great impact on the PCB board. Therefore, it is necessary to clean the PCB board before installing or assembling components. The dust removal and cleaning of the surface of the PCB board is generally done by vacuum equipment or wiping, the dust removal efficiency is low, and the dust removal effect is poor

The invention discloses an automatic PCB dust removal system. The automatic PCB dust removal system is arranged between a printing machine and a plate making machine. The automatic PCB dust removal system comprises a PLC, an electromagnetic valve, a light sensing device, an air supply pipe and an air outlet device, wherein the light sensing device is electrically connected with the PLC and sends a signal to the PLC, the PLC is electrically connected with the electromagnetic valve and sends a signal to the electromagnetic valve, and the air supply pipe is connected with the air outlet device; and a deflation valve is installed on the air supply pipe, the electromagnetic valve is electrically connected with the deflation valve and controls opening and closing of the deflation valve, and a plurality of air outlets are uniformly formed in the air outlet device. The automatic PCB dust removal system has the advantages that powder, crushed materials and dust on the surface of a PCB are removed, the welding quality hidden danger caused by pollution on the surface of the PCB is effectively prevented, and the welding quality of PCB components is ensured, so that the more reliable process improvement of the 10-level standard or above of a dust-free workshop is achieved; the welding reliability of products is improved, and the situation that the service life in the circulating market is shortened after the products are welded is avoided.
Description
technical field [0001] The invention relates to a dust removal device, in particular to a PCB automatic dust removal system. Background technique [0002] PCB board is the abbreviation of English (Printed Circuie Board) printed PCB circuit board. Usually on the insulating material, according to the predetermined design, the conductive pattern made of printed circuit, printed component or a combination of the two is called printed circuit. The conductive pattern that provides electrical connection between components on an insulating substrate is called a printed circuit. In this way, the finished board of printed circuit or printed circuit is called printed circuit board, also known as printed board or printed circuit board. Circuit boards can be divided into the following categories according to their functions: single-sided circuit boards, double-sided circuit boards, multi-layer circuit boards, aluminum-based circuit boards, impedance circuit boards, FPC flexible circuit...
