Title:
COMPONENT MOUNTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/017788
Kind Code:
A1
Abstract:
This component mounting machine (10) includes: an adsorption nozzle (6) having a nozzle adsorption surface (6a); a camera (24) for acquiring nozzle imaging data (100) of a tip end of the adsorption nozzle (6); and a control device (30) for determining quality of the nozzle adsorption surface (6a). The nozzle imaging data (100) contains a nozzle region in which the tip end of the adsorption nozzle (6) is imaged and a background region in which a background that is lower than the tip end of the adsorption nozzle (6) is imaged. The control device (30) calculates the lowermost end position of the nozzle adsorption surface (6a) or foreign matter (110) adhered to the nozzle adsorption surface (6a), calculates a first height (h1) and a second height (h2) that are positions, in the vertical direction, of the nozzle adsorption surface (6a) or the foreign matter (110) adhered to the nozzle adsorption surface (6a) in a first position (L1) that is apart from the lowermost end position by a first setting distance or more and in a second position (L2) that is apart from the lowermost end position by a second setting distance or more, calculates a difference for calculating a first difference (I1) between the first height (h1) and the height of the lowermost end position, and a second difference (I2) between the second height (h2) and the height of the lowermost end position, and determines the quality of the nozzle adsorption surface (6a) on the basis of the difference that is the smallest of the first difference (I1) and the second difference (I2).
