Embodiment Construction

[0024] Now in conjunction with the accompanying drawings, the preferred embodiments and preferred embodiments of the present invention will be described in detail.

[0025] Such as figure 1 As shown, the present invention provides a preferred embodiment of a multi-angle lighting device.

[0026] The multi-angle lighting device includes a light source module 10 and a control module (not shown in the drawings) for controlling the switch and / or brightness of the light source module 10. The light source module 10 includes a plurality of The light source components 101 are set at different lighting angles and are all set towards the same lighting area.

[0027] By setting the light source components 101 at different positions in the three-dimensional space, the products on the corresponding lighting area can be illuminated in all aspects, so that the acquisition imaging and defect detection of the products to be inspected can be realized at different angles, with low cost, stable ...

Abstract

The invention relates to the technical field of glass cover plate detection, in particular to a multi-angle lighting device. The multi-angle lighting device comprises a light source module and a control module for controlling the on and off and / or brightness of the light source module, the light source module comprises a plurality of light source components which are disposed at different lightingangles in a three-dimensional space and all face the same lighting area. By virtue of the light source module which face the same lighting area and can light at different lighting angles in a three-dimensional space, and the control module controlling the on and off and / or brightness of the light source module, the collection imaging and defect detection at different angles of a product to be detected can be realized. The multi-angle lighting device has the advantages of low cost, stable performance and low omission factor.

Description

technical field [0001] The invention relates to the technical field of glass cover detection, in particular to a multi-angle lighting device and a collection system. Background technique [0002] With the rapid development of mobile networks and mobile phones, people have higher and higher requirements for mobile phones and their screens. The inspection of glass cover is an important part of mobile phone quality inspection. [0003] According to the test results and experience of the smartphone cover plate, different types of defects on the glass cover plate of the mobile phone need to be observed from different angles to see, while the existing technology can only complete the glass cover through one angle or certain angles. Therefore, only some defects can be detected, and the detection of multiple types of defects cannot be realized, so it may cause quality problems such as missed inspections and high defect rates. Contents of the invention [0004] The technical probl...
