Electronic return component supply device and electronic return component supply-taking out device

Abstract

An electronic circuit component supply device and an electronic circuit component supply / retrieval device having a supply position detection function can easily improve the supply accuracy of electronic circuit components held by a conveyor belt. A reference mark (100) is provided at the central part of the front end face (98) of the tooth (96) of the sprocket (90), so that the light reflectance of the reference mark (100) is higher than that of the front end face (98) . Before the electronic circuit components are loaded on the printed circuit wiring board, the wiring board imaging device photographs the reference mark (100) to obtain its center position error. The delivery hole (56) and the parts receiving recess are formed with high positional accuracy. The center position error of the reference mark (100) is equal to the position error of the parts receiving recess positioned at the part supply position. To eliminate this position error, the movement of the XY robot is controlled. The data is used to correct the part extraction position of the suction nozzle. It is also possible to provide recesses on the teeth, whereby reference marks are provided.

Description

technical field [0001] The present invention relates to an electronic circuit component supply device and an electronic circuit component supply / retrieval device, and particularly relates to a technique for improving the supply accuracy of electronic circuit components held by conveyor belts. Background technique [0002] Electronic circuit components are components that are mounted on a circuit board and constitute an electronic circuit, and are held by, for example, a conveyor belt, adjusted and supplied by a tape feed mechanism. A plurality of conveyance holes and component accommodating recesses are formed side by side on the conveyor belt at predetermined relative positions, and electronic circuit components are accommodated in the respective component accommodating recesses. The conveyor belt is conveyed by, for example, sprockets. The sprocket has a plurality of teeth arranged at equal angular intervals on its outer peripheral surface. Some of these teeth are engaged...

Problems solved by technology

[0003] When positioning such an electronic circuit component at the component supply position, it is necessary to position it with good precision, but a positional error may occur due to a manufacturing error or an assembly error of the tape feed mechanism, and it may be possible to remove the electronic circuit component from the component accommodating recess. fetch error
