Cleaning and appearance detecting machine and detecting technology thereof

Abstract

The invention discloses a cleaning and appearance detecting machine and a detecting technology thereof. The cleaning and appearance detecting machine comprises a material belt, a feed-discharge carrying mechanism, a rotary table, a feed-discharge station, a working station, a jig rotation driving mechanism, a jig clamping limiting mechanism, a product cleaning mechanism, a product wiping mechanism and a product appearance detecting mechanism, wherein the material belt is arranged at the outer side part of a rack; at least two products are placed on the material belt at intervals; the rotary table is arranged on the rack; the feed-discharge station and the working station are arranged in the periphery of the rotary table at an interval; product jigs are arranged on the feed-discharge station and the working station; the feed-discharge carrying mechanism is arranged on the outer side of the feed-discharge station; the jig rotation driving mechanism and the jig clamping limiting mechanism are arranged on the working station; the product cleaning mechanism, the product wiping mechanism and the product appearance detecting mechanism are arranged on the working station. The cleaning and appearance detecting machine detects the surface and appearance of a product in a full-automatic manner, and is compact in structural design and high in degree of automation, detecting efficiency and quality.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to a cleaning and appearance testing machine and a testing process thereof. Background technique [0002] In recent years, the electronics industry has developed rapidly. With the improvement of computer hardware, the improvement of software and the emergence of various APPs, the functions and types of electronic products are developing in a diversified direction. The shells of electronic products are generally made of plastic or metal. Covering the protective paint layer, the appearance quality requirements of electronic products are high. Therefore, after the product assembly process and the laser engraving process, it is necessary to pass the product appearance inspection process to check the appearance, scratches, fingerprints, etc. Inspection and screening of dents, etc., to pick out defective products; traditional manual or semi-automatic product adapter production for app...

Problems solved by technology

[0002] In recent years, the electronics industry has developed rapidly. With the improvement of computer hardware, the improvement of software and the emergence of various APPs, the functions and types of electronic products are developing in a diversified direction. The shells of electronic products are generally made of plastic or metal. Covering the protective paint layer, the appearance quality requirements of electronic products are high. Therefore, after the product assembly process and the laser engraving process, it is necessary to pass the product appearance inspection process to check the appearance, scratches, fingerprints, etc. Inspection and screening of dents, etc., to pick out defective products; traditional manual or semi-automatic product adapter production for appearance inspection is gradually eliminated, and more companies are gradually transforming to automated production; in the process of product appearance inspection automation, products The external shape is the biggest constraint; various electronic products have different external shapes, including rectangles, cylinders and other irregular shapes, the most common shape is rectangles, such as mobile phones, tablet computers, batteries, power adapters etc.; in addition, in order to ensure the smoothness of the side and top corners of electronic products, arc surfaces are generally used for transition; in the actual production process, limited by the external structure of the product adapter, the appearance inspection needs to be aimed at the surface and edge (arc surface) respectively. ) and vertex (arc angle) are tested separately, so there are many testing process steps involved. In addition, because the product adapter is exposed before testing, its surface may accumulate dust particles or cause surface contamination due to other reasons. Affect the accuracy of subsequent high-precision appearance inspection
