Substrate transfer conveyor variable chain guide part transfer device of printed circuit board inspection machine

摘要

The present invention relates to a substrate conveyor variable chain guide portion transfer device of the PCB inspection machine, the technical configuration, the reference chain applying guide portion 1 and the substrate transfer chain (6) is installed on one side, spaced apart therefrom The variable chain guide part 3 and the substrate transfer chain 6 are installed inside the fixed chain guide part 3, and the fixed guide part 5 is installed on the other side of the base 8, and the reference chain guide part 2 and the fixed guide part are installed. (5) between the support shaft (9) is arranged horizontally, the slide unit 11 and the conveying portion (4) provided with a ball bushing (10) in the inner side is provided on the bottom of the variable change guide portion (3), the slide The fixing groove 13 formed at the bottom of one side of the unit 11 is fastened to the anti-rotation guide block 12 mounted on the upper portion of the base 8, and the ballscrew 7 is fixed to both sides of the variable chain guide part 3. Spheres rolled between the reference chain guide portion 2 and the fixed guide portion 5 through It consists of.;Accordingly, installation is extremely easy even in a narrow space, and the manufacturing cost is reduced because the parts price is very low, and the variable chain guide part is transferred smoothly, so that the width of the substrate conveyor is increased in the left and right directions of the substrate conveyor. By quickly adjusting the workability is improved, it is easy to manufacture and install by a simple configuration.
