[0001] The utility model relates to the technical field of PCB steel mesh micropore detection, in particular to a PCB steel mesh micropore detection and repairing instrument. Background Art

[0002] At present, the steel mesh is also called the SMT template, which is a special mold for SMT. Its main function is to help the deposition of solder paste. The purpose is to transfer the accurate amount of solder paste to the accurate position on the empty PCB. After the steel mesh is used, flux will remain on the surface, and the flux on the surface of the steel mesh needs to be cleaned. After cleaning, the steel mesh still needs to be inspected to prevent flux residue. To avoid the clogging of the steel mesh micropores by flux when the steel mesh is reused, problems such as PCB board leakage or insufficient tin will occur, affecting product quality and production efficiency. The existing detection device requires manual transportation of the steel mesh to the detection component, and classification after detection one by one, which is time-consuming and labor-intensive, and the detection efficiency is low. At the same time, the existing detection device has no repair function. After the steel mesh is tested, it needs to be manually transported to the repair process for repair, which further reduces the efficiency of steel mesh micropore detection and repair.

[0025] The horizontal pushing component 3 includes a connecting box 31, in which a cylinder controlled by the flux detection component 2 is arranged, and a push rod 32 is arranged on the side of the connecting box 31 close to the conveyor belt 12, and the push rod 32 is pushed out of the connecting box 31 by the cylinder, and a push plate 33 with the same thickness as the fixed plate 11 is fixedly installed at one end of the push rod 32 close to the conveyor belt 12. When the flux detection component 2 does not detect the presence of residual flux on the PCB steel mesh, the push plate 33 is retracted into the gap opened on the fixed plate 11 by the cylinder to prevent the PCB steel mesh from being blocked when being transported on the conveyor belt 12, and the motor is started to transport the PCB steel mesh from the other end of the conveyor belt 12 to the outside of the instrument. When the flux detection component 2 does not detect the presence of residual flux on the PCB steel mesh, the motor is turned off to stop the PCB steel mesh from continuing to move on the conveyor belt 12, and the cylinder is started to extend the push rod 32 from the connecting box 31, and the PCB steel mesh with residual flux is pushed into the cleaning component 4 through the gap perpendicular to the direction of the conveyor belt 12 for cleaning by the push plate 33.

[0026] The cleaning assembly 4 includes two oppositely arranged vertical plates 44, which are fixedly mounted on both sides of the notch of the fixed plate 11 on the side away from the conveyor belt 12.
