Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The invention provides a button automatic sorting method, comprising the following steps:

[0049] (1) Buttons of different shapes and diameters are delivered to the transmission unit by the feeding unit;

[0050](2) Use the transmission unit to transmit the button to the location of the intelligent detection unit with a rear light source, and use the smart camera to detect the geometric characteristics of the button; compare the measured geometric characteristic parameters with the expected parameters to determine whether the button is Defective product; if it is a defective product, the defective product will be sorted out through the sorting unit, and the genuine product will enter the subsequent process;

[0051] (3) Use the transmission unit to transmit the button to the location of the intelligent detection unit with the...

Abstract

The invention provides an automatic button sorting method. The automatic button sorting method comprises the steps that (1) buttons are conveyed to a transmission unit through a feeding unit; (2) geometrical characteristics of the buttons are detected through an intelligent camera, and whether the buttons are inferior-quality products or not is judged; (3) images of front faces of the buttons are collected through the intelligent camera, the characteristics of the front faces of the buttons are extracted, and whether defects exist on the front faces of the buttons or not is judged; (4) the buttons flow out from a U-shaped steering sliding way, and automatic face overturning is achieved; and (5) images of back faces of the buttons are collected through the intelligent camera, the characteristics of the back faces of the buttons are extracted, whether defects exist on the back faces of the buttons or not is judged, if the defects exist, the inferior-quality products are sorted out through a sorting unit, qualified products enter a qualified product groove, and sorting is completed. The automatic button sorting method solves the technical problems that at present, the two faces cannot be detected at the same time, unknown buttons cannot be detected, abnormal-shaped buttons cannot be detected, and the detecting speed is not high enough. The invention further provides an automatic button sorting device.

Description

technical field [0001] The invention belongs to the field of industrial automation, and in particular relates to a button automatic sorting method and device. Background technique [0002] During the production process of buttons, due to technological means, there may be geometrical deviations, breakage, scratches, cracks, and incomplete printing patterns. At present, there are two kinds of inspection methods for buttons: manual inspection and automatic inspection. The outstanding problems of manual inspection are: the efficiency of manual inspection is low, the labor cost is high, and at the same time, due to manual negligence, false inspections and missed inspections will occur. . [0003] The Chinese invention patent "Button Identification Device" with the patent number ZL200910129286.2 discloses a button identification device using automatic detection. The button identification device in this patent has: a button feeding device, a button transmission device and a button...
