Semi-automatic parallel light LED exposure machine

Abstract

The invention discloses a semi-automatic parallel light LED exposure machine which comprises a machine body, a lighting LED upper lamp box, a 4CCD image processing mechanism, a frame alignment mechanism, a man-machine interaction interface and a control device, the machine body comprises an alignment machine body on the front portion and an exposure machine body on the rear portion, and fixed walls are fixedly arranged on the two sides of the upper end of the alignment machine body; and a sliding rail installation groove is fixedly formed in the opposite face of the fixed wall, an upper Z-axissliding rail and a lower Z-axis sliding rail are fixedly installed in the sliding rail installation groove, the lower Z-axis sliding rail is fixedly connected with the frame alignment mechanism, andthe upper Z-axis sliding rail is fixedly connected with four CCD image processing mechanisms. The lighting LED upper lamp box is fixedly installed on the side end face of the side, close to the alignment machine body, of the upper end of the exposure machine body, an exposure chamber is fixedly installed in the exposure machine body, and a UV-LED lamp is fixedly arranged in the exposure chamber. High-precision image acquisition and automatic alignment are carried out through the four network card CCD cameras, exposure of a PCB dry film is carried out through an UV-LED lamp scanning light source, and parallelization processing does not need to be carried out on a large amount of complex optical glass.

Description

technical field [0001] The invention relates to the field of exposure machinery, more specifically, the invention is a semi-automatic parallel light LED exposure machine. Background technique [0002] At present, the original line exposure machines of most PCB companies in China use manual alignment or simple mechanical alignment; the exposure light source uses traditional mercury lamps and a large number of optical glass for light parallelization. [0003] Manual alignment or mechanical PIN alignment, the alignment accuracy is poor, usually the operator's proficiency determines the speed and accuracy of alignment, the accuracy of manual or PIN and manual exposure is roughly within the range of 100um. With the development of industrial automation, circuit boards will become thinner and thinner, with finer lines and more layers. Manual and mechanical external methods are powerless for high-precision boards. In addition, pattern transfer is the most important production proc...

Problems solved by technology

[0004] The use of traditional mercury lamps consumes a lot of electricity, has low luminous efficiency, pollutes the environment, and affects the health of operators.

The traditional parallel light exposure machine uses a lot of optical glass and multiple mirrors, which is expensive, and debugging and installation require professionals

It is fragile during use and maintenance, and there is a hidden danger of harming the operator's body
