Auxiliary device used for PCBA processing SMT stokehole visual inspection and using method

Abstract

The invention provides an auxiliary device used for PCBA processing SMT stokehole visual inspection and a using method. The device comprises a positioning support, an auxiliary observation module, an observation drive module and a control module; parallel production line equipment guide rails are arranged on the two sides of a PCBA working face, the positioning support is arranged on the upper portions of the production line equipment guide rails, and the auxiliary observation module is arranged on the upper portion of the positioning support; the control module is connected with the observation drive module and drives the auxiliary observation module to move transversely and longitudinally along the positioning support, and observation of all observation points of the PCBA working face is achieved; the auxiliary observation module comprises a pipe sleeve, a light path pipe, a downward-bent objective lens opening and an upward-bent ocular lens opening; a first lens and a second lens are arranged at the bending position of the light path pipe and the objective lens opening and the bending position of the light path pipe and the ocular lens opening correspondingly, and are parallel to each other; and a telescopic structure is arranged in the middle of the sleeve pipe outside the light path pipe. Transverse and longitudinal movement of the whole auxiliary observation module and the objective lens opening is controlled, and observation to the whole PCBA working face on the side of a first transverse support is achieved.

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...

Problems solved by technology

[0007] In view of the prior art, the above-mentioned existing PCBA pre-furnace visual inspection method easily leads to physical fatigue of engineers, and there are quality risks near the inner side of the production line. The poor observation effect affects the judgment of engineers, which leads to misjudgment of the first article, and ultimately affects the defects of PCBA batches. , the present invention provides an auxiliary device and method of use for PCBA processing SMT visual inspection in front of the furnace, to solve the above technical problems
