Description

Technical Field

[0001] The present invention relates to the technical field of machine vision detection, and in particular to a detection device. Background Art

[0002] With the continuous development of science and technology, smart devices have become one of the indispensable tools in people's lives. While people are pursuing performance, their requirements for the appearance of smart devices are also constantly increasing. Mobile phone covers are key components in smart devices, which directly affect the performance and appearance of smart devices. Therefore, the appearance inspection of mobile phone covers is a crucial part of the production process of smart devices. Before the mobile phone cover is put into use, it is also necessary to coat it to ensure that the cover can achieve the corresponding anti-scratch, anti-fall, anti-fingerprint and other characteristics. Therefore, the inspection before coating can greatly improve the pass rate after coating.

[0003] In the detection scheme of the front cover plate before coating, the existing technology is mainly divided into two types: manual detection and machine vision detection. Among them, manual detection is carried out through measuring instruments (such as two-dimensional image measuring instruments, magnifying glasses, film rulers, etc.), by directly reading the readings of the measuring instruments, or by observing the surface of the cover plate with the naked eye under auxiliary lighting, so as to evaluate and measure the appearance defects of the cover plate. Due to the influence of human subjective factors, manual detection methods have the disadvantages of high misjudgment rate, unstable detection quality, low detection efficiency, etc., which makes it difficult to ensure the stability of product quality. More importantly, there is a health risk of reducing the eyesight of inspection workers. Manual detection methods consume a lot of manpower and high costs in mass production. The machine vision detection equipment used for machine vision detection uses a mechanical arm to pick up and move the mobile phone cover plate during the transportation process. Because the mobile phone cover plate before coating does not have the scratch resistance and high hardness after coating, it is very easy to cause scratches and deformation, resulting in a high scrap rate. Summary of the invention

[0004] In view of this, an embodiment of the present invention provides a detection device, which is mainly used to solve the problem that the existing mobile phone cover detection consumes manpower or is easily scratched and deformed.

[0005] In order to achieve the above object, the present invention mainly provides the following technical solutions:

[0006] The present invention provides a detection device, the detection device comprising:

[0007] At least one table assembly, the table assembly at least includes a transfer power assembly and a conveyor belt, the conveyor belt is connected to the transfer power assembly, the conveyor belt is used to support the object to be detected, and the transfer power assembly is used to drive the conveyor belt to move and transport the object to be detected;

[0008] At least one image acquisition component, which is opposite to the table component and is used to acquire the image of the object to be detected on the conveyor belt.

[0009] A detection device proposed by the present invention mainly supports the object to be detected by setting a conveyor belt, and the transfer power component drives the conveyor belt to move, so as to realize the transmission of the object to be detected, and performs image acquisition and other detection of the object to be detected during the transmission process, so as to realize automatic detection and avoid damage caused by clamping and moving. In the prior art, manual detection means are affected by human subjective factors, and have the disadvantages of high misjudgment rate, unstable detection quality, low detection efficiency, etc. Machine vision detection uses a mechanical arm to pick up and move the mobile phone cover, which is very easy to cause scratches and deformation. Compared with the prior art, in this application document, the object to be detected is placed above the conveyor belt, and the object to be detected is supported by the conveyor belt supporting the object below, and the conveyor belt is driven by the transfer power component to move the object to be detected, so that the object to be detected can pass through the image acquisition component or other auxiliary detection parts on the transmission path in turn, so as to realize automatic detection, without human participation, with high accuracy, and avoid the easy damage to the object to be detected caused by the clamping and moving of the mechanical arm.

[0034] In the following embodiments of the present application, Figure 1 As an example of the detection device shown in the figure, in the following embodiments of the present application, the directions are defined as: the first direction is as follows Figure 1 The Z direction is the direction in which the conveyor belt supports the object to be detected 03, and in actual use, it is the vertical direction; the second direction is the X direction, the second direction is perpendicular to the conveying direction of the object to be detected 03, and perpendicular to the Z direction in which the conveyor belt supports the object to be detected 03; the third direction is the Y direction, and the third direction is the conveying direction of the object to be detected 03.

[0035] like Figure 1 As shown, the detection device includes two first table components 1 and two second table components 6. The two first table components 1 are arranged side by side in the X direction, and the second table components 6 correspond to the first table components 1 one by one and are located behind the first table components 1 in the Y direction.

The auxiliary axis can have the same structure as the axis component 132, or it can have a different structure. The auxiliary axis is used to cooperate with the positioning component 10 described later to locate the object to be detected 03.
