Workpiece Supplying Device, Picking Device, Timepiece Assembling Apparatus, And Picking Method

Abstract

A workpiece supplying device includes a pallet that has a groove portion being disposed in an arc state and a stepped portion including a stepped surface intersecting a circumferential direction of the pallet and accommodates a workpiece, and a vibration unit that drives the pallet due to vibration and transports the workpiece in the circumferential direction toward the stepped portion. A plurality of the groove portions are disposed in a concentric manner.

Description

technical field [0001] The present invention relates to a workpiece supply device, a pick-up device, a watch assembly device and a pick-up method. Background technique [0002] Conventionally, a production line for mechanical assembly of products has multiple manufacturing processes, and components required for each manufacturing process are supplied, and robots or the like use image recognition or the like to grasp the supplied components and move the components to required positions for assembly. [0003] In the bin pick-up device of Patent Document 1, the bottom surface of the tray containing the workpiece can be separated from the square wall surfaces of the tray, and the bottom surface of the tray and the wall surface of the tray can move up and down relative to each other, so that the height of the wall surface of the tray is the same as the height of the tray inside the tray. The workpiece height changes accordingly. [0004] Japanese Patent Laid-Open No. 2010-105081...

AI Technical Summary

Problems solved by technology

[0005] However, in the bin pick-up device of Patent Document 1, there is a problem that it is difficult to accurately recognize the positions and postures of the workpieces even if three-dimensional image recognition is performed because the workpieces are piled up like a mountain.

In addition, the structure and operation of the chuck for picking out the workpiece are complicated, and there is a problem that it is difficult to pick out the workpiece accurately.

In addition, due to these problems, there is a problem that the assembly cycle time is long

[0006] In addition, in general, when the shape of the workpiece is, for example, a plate-shaped workpiece that must be reversed front and back, a workpiece with protrusions on the outer surface of the workpiece, and a workpiece that is inclined when placed on a flat surface (so-called poor stability) In the case of supply and pick-up, similar to the above, it is difficult to accurately recognize the position and posture of the workpiece, and there are problems such as time required for selection and selection errors.
