Problems solved by technology

[0003] At present, most product appearance inspections mainly rely on manual visual inspection, which is prone to missing inspections and unstable inspections, and cannot ensure the appearance quality of ex-factory products. At the same time, manual inspection is labor-intensive and inefficient.

Embodiment 1

[0084] Such as figure 1 and 2 As shown, this embodiment provides an appearance inspection device, which is mainly used for inspecting the appearance of a mobile phone 1 ′, a tablet computer, and the like. Taking the mobile phone 1' as an example, its appearance generally includes a first main surface 11' and a second main surface 12' set opposite to each other, and a middle frame part between the first main surface 11' and the second main surface 12' 13', and also includes a groove concavely set on the first main surface 11', and a plane convexly set on the second main surface 12', wherein the groove can be used to set the earpiece part, and the convexly set on the second main surface The plane on the 12' can be the plane where the rear camera of the mobile phone 1' protrudes from the housing of the mobile phone. Of course, in other products, the groove can be set on the second main surface 12', the convex plane can be set on the first main surface 11', or both the first mai...

Embodiment 2

[0108] This embodiment discloses a product appearance detection method, including the following steps:

[0109] 1) Inspecting the first main surface at the first inspection station, and inspecting the grooves and / or raised planes on the first main surface at the second inspection station;

[0110] 2) turning over the product to be tested;

[0111] 3) The second main surface is inspected at the first inspection station, and the grooves and / or convex planes of the second main surface are inspected at the second inspection station.

[0112] The appearance detection method of this embodiment detects the main surface of one side and other features of the main surface, and then detects the main surface of the other side and other features of the main surface, so as to avoid repeated flipping of the product during the detection process. High-efficiency detection of product appearance is realized.

[0113] As an option, step 1) or step 3) also includes detecting the middle frame por...

Abstract

The invention discloses appearance detection equipment and an appearance detection method for a to-be-detected product and belongs to the technical field of appearance detection. The appearance detection equipment comprises a conveying system and detection working stations, the conveying system comprises a conveying rail, a feeding clamp, a discharging clamp and a conveying device, and the feedingclamp and the discharging clamp are located on the conveying rail; a main surface detection system, a middle frame detection system, a concave face detection system and a convex face detection systemare arranged along the conveying system, and the concave face detection system is used for detecting a groove formed in a first main surface; the convex face detection system is used for detecting aplane which is raised on a second main surface. The appearance detection method comprises the steps that the first main surface of the to-be-detected product is detected on the first detection workingstation and the groove and / or the raised plane of the first main surface is detected on the second detection working station; then, overturning is conducted, the second main surface is detected on the first detection working station. According to the appearance detection equipment and the appearance detection method, unification and standardization of product appearance detection are achieved, and high-efficiency detection is achieved.

Description

technical field [0001] The invention relates to the technical field of appearance inspection, in particular to an appearance inspection device and an appearance inspection method of a product to be inspected. Background technique [0002] With the improvement of material living standards, consumers' requirements for product appearance are also constantly improving. Especially for electronic products, such as smart terminal products such as mobile phones and tablet computers, the processing precision is high. If there are foreign objects, pinholes, impurities, different colors, bubbles, bumps, scratches, bright spots and other defects on the appearance of the product, it will greatly affect The quality index and aesthetics of the product, so it is necessary to carry out a systematic defect detection on the product before it leaves the factory. [0003] At present, most product appearance inspections mainly rely on manual visual inspections, which are prone to missing inspect...
