Abstract

The present invention provides an auxiliary device for visual inspection in front of PCBA processing SMT furnace and its use method. The device includes a positioning bracket, auxiliary observation, observation drive and control module; parallel production line equipment guide rails are arranged on both sides of the PCBA working surface , the positioning bracket is set on the upper part of the guide rail of the production line equipment, and the auxiliary observation module is set on the upper part of the positioning bracket; the control module is connected with the observation drive module, and drives the auxiliary observation module to move horizontally and vertically along the positioning bracket to realize the observation of each observation point on the PCBA working surface; The auxiliary observation module includes a tube sleeve, an optical tube, a downwardly bent objective lens port and an upwardly bent eyepiece port; The two mirrors are parallel; the middle part of the casing outside the light path tube is provided with a retractable structure. The invention controls the horizontal and vertical movement of the auxiliary observation module as a whole and the objective lens port, and realizes the observation of the entire PCBA working surface on the side of the first horizontal support.

Description

technical field [0001] The invention belongs to the technical field of PCBA processing, and in particular relates to an auxiliary device for visual inspection in front of SMT furnace of PCBA processing and a using method. Background technique [0002] PCBA is the abbreviation of Printed Circuit Board Assembly, which means that the empty PCB board passes through the SMT upper part, or through the entire process of DIP plug-in. [0003] SMT is the abbreviation of Surface Mounted Technology, surface mount technology. [0004] During the rapid development of the electronics industry, PCBA has become an important hardware carrier in the server architecture. In the actual production of PCBA, every time the line is changed, the first piece will be cast first to confirm the correctness of the R&D design, the stability of the line equipment and the process, so as to avoid batches of defective products. The confirmation of the first piece before the reflow oven is done manually by e...
