Semi-automatic alignment and exposure device of printed circuit board (PCB)

Abstract

The invention discloses a semi-automatic alignment and exposure device of a printed circuit board (PCB). The semi-automatic alignment and exposure device comprises an alignment chamber and an exposure chamber, wherein an upper slipway and a lower slipway are respectively arranged in the alignment chamber and the exposure chamber and are in parallel, an upper alignment platform is arranged in the upper slipway and comprises a first working table, a first upper cover and an alignment mechanism, the first working table can slide along the upper slipway, the first upper cover is hinged with the first working table, a signal acquisition device is arranged above the first working table and can slide along the alignment chamber, the exposure chamber comprises an exposure device, the exposure device can do vertical movement along the exposure chamber, a lower alignment platform comprises a second working table, a second upper cover and an alignment mechanism, the second working table can slide along the lower slipway, the second upper cover is hinged with the second working table, the first working table and the second working table do movement relative to each other by a driving device, the semi-automatic alignment and exposure device also comprises a control system, and the control system controls opening and closing of a partition plate, controls the first working table and the second working table to do movement relative to each other and controls the alignment mechanism to automatically align. The semi-automatic alignment and exposure device has the advantages of positioning accuracy and high positioning efficiency.

Description

technical field [0001] The invention relates to an exposure machine, in particular to a semi-automatic alignment and exposure device for PCB boards. Background technique [0002] The PCB board needs to be aligned before exposure. The existing alignment device is manually aligned. There are some differences in this alignment. For example, the alignment between the PCB board and the film is observed by human eyes during alignment. In this case, the alignment error is large, the alignment accuracy is not high, and the alignment efficiency is relatively low. At the same time, due to the inaccurate alignment, after the PCB board is exposed, the qualified rate of the PCB board is relatively low. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a semi-automatic alignment and exposure device for PCB boards. [0004] Technical scheme of the present invention is: [0005] A semi-automatic alignment an...
