Component Mounting Line

Abstract

The automatic changing device (26) is moved along the moving route of the front surface side of the component mounting production line through the driving wheel (76), and the automatic changing device (26) is moved to the multiple component mounting machines (12) constituting the component mounting production line (10). The feeder setting part (24) installs the feeder (14) and removes the feeder (14) from the feeder setting part (24) of the multiple component mounting machines (12) constituting the component mounting line (10) . The position detection device (81) for detecting the position of the automatic changer is composed of an open timing belt (82) provided so as to extend linearly along the moving path on the front surface side of the component mounting line, while maintaining meshing with the teeth of the timing belt The synchronous pulley (83) that moves with the automatic changing device and the rotary encoder (87) that detects the rotation angle of the synchronous pulley are composed of the position detection device (81) that outputs pulses to the rotary encoder A count is performed to detect the position of the automatic changer.

Description

technical field [0001] The present invention relates to a component mounting production line equipped with an automatic changing device for automatically installing feeders and supplying feeders to the feeder installation parts of a plurality of component mounting machines arranged along the conveying direction of circuit boards. The feeder is removed from the feeder installation section of the multiple component mounting machine. Background technique [0002] Such a component mounting line is described in Patent Document 1 (International Publication No. WO2014 / 010083), in which an automatic changer (loader) can be installed in a mobile unit along an array of multiple component mounting machines constituting the component mounting line. Set in a way of moving on the route, move the automatic changer to the front surface of the component mounting machine instructed by the production operation (production program), etc., and set the feeder to the feeder setting part of the com...

Problems solved by technology

[0007] In the above-mentioned Patent Document 1, the automatic changer is moved by the meshing of the rack and the pinion teeth, but there is a disadvantage that the meshing state of the rack and the pinion teeth is different due to the manufacturing difference of these structural elements, assembly, etc. Differences, tooth wear, etc. may cause deterioration, and the teeth may interfere with each other to prevent smooth rotation, which may generate large noise or cause damage to the teeth, etc.
