Workpiece Appearance Gloss Detection Technology

Abstract

The invention relates to a workpiece appearance gloss detection process method which comprises the following steps: (1) conveying an empty tray and a workpiece to a detection area by virtue of a first moving rail and a second moving rail, wherein the empty tray is transferred to a third moving rail; (2) jacking the workpiece to a preset height needed by detection by virtue of a vertical positioning device; (3) pushing the workpiece to a preset position needed by detection by virtue of a horizontal positioning device; (4) respectively detecting two stations of the workpiece by virtue of a gloss module; (5) resetting and loosening the clamped workpiece by virtue of the horizontal positioning device, and descending and resetting by virtue of the vertical positioning device; and (6) conveying the tray away from a gloss detection device by virtue of the third moving rail. According to the method disclosed by the invention, automation of the whole detection process is realized by utilizing the moving rails and the positioning devices; the tray can be transferred by virtue of the first moving rail and the third moving rail which are arranged in a staggered mode; the next process can be conveniently performed by virtue of simultaneous feeding of the tray and the workpiece and simultaneous discharging of the tray and the workpiece; and according to the horizontal and vertical positioning steps, the workpiece can be accurately positioned at an optimal detection position.

Description

Technical field [0001] The invention relates to a gloss detection of electronic products or electronic equipment, in particular to a process method for detecting the gloss of a workpiece appearance. Background technique [0002] The surface gloss refers to the measured surface gloss expressed by a numerical value. Gloss is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrically prescribed conditions. Therefore, it expresses the reflective properties with direction selection, which mainly depends on the angle of light source illumination and observation. Instrument measurement usually uses 20°, 60° or 85° angles of illumination and detection signals. Different application fields use different angle measuring instruments. [0003] However, the existing gloss detection devices are usually contact-type, and contact-type measurement often has the risk of scratching the surface of the measured object. Non-contact measurement c...

[0003] However, the existing gloss detection devices are usually contact-type, and contact-type measurement often has the risk of scratching the surface of the measured object

Non-contact measurement can avoid scratching the measured object, but when the measured object is deformed or the clamping is misaligned, the reflected light will deviate from the light receiving hole and affect the detection result, and even the gloss value cannot be measured

[0004] Therefore, the company has applied for a Chinese patent, the application number is: 201310749514.2, and the name of the invention is: non-contact gloss meter, which can realize non-contact detection of product gloss, but for products shaped like laptops, it needs Both the upper surface and the side surface are tested for glossiness. The existing detection device can only detect one surface, and two different detection equipment are needed to complete the detection, which is not only cumbersome but also has low reliability.

[0005] The process of multi-point inspection of the same product is complicated and the steps are complicated. Before the inspection, the product needs to be sent into the inspection area, and accurately positioned and transported out of the inspection area. The above-mentioned processes need to be automated.
