Description

Technical Field

[0001] The utility model belongs to the field of CCD visual detection, in particular to a simple backlight position adjustment mechanism, which is used for a detection mechanism compatible with materials of different sizes, can conveniently adjust the light source position, and is suitable for various detection equipment. Background Art

[0002] The structure of the prior art solution is as follows Figure 2 As shown, the backlight source is fixed to the vacuum chamber by bolts, and the transparent suction plate is fixed to the vacuum chamber by bolts. The disadvantages of this conventional method are: high cost / energy consumption. In order to have a wide compatibility range, a large-sized backlight source is usually selected, which directly leads to increased costs and waste of energy; poor versatility / adjustability. Each time the product is changed, it may involve the replacement of the entire mechanism, or the adjustment may be troublesome. In order to adjust the position of the backlight source, the transparent suction plate above must be removed, and the operation is cumbersome.

[0003] For example, Chinese patent CN205942166U (published on February 8, 2017) provides a detection device for a backlight module, which includes: a transparent film, a workbench, and a vacuum cavity located below the workbench; a groove for placing the backlight product to be tested and a test contact for lighting the backlight module are provided in the middle of the workbench, and a transparent film covering the groove is provided above the workbench. The utility model makes the structure simple, the adjustment time of the backlight module is short, the adjustment time is shortened, and the overall detection time of the equipment is shortened; in addition, multiple vacuum adsorption ports are provided, which can complete the detection of the inside of the thin and light backlight product, enhance the comprehensiveness of the detection, avoid the drawbacks of missed detection and failure to detect, but cannot solve the problem of increasing costs due to the desire for a wide compatible range. Another example is Chinese patent CN207094370U (published on March 13, 2018) relates to a glass surface defect detection device, and in particular, to an adjustable position backlight component used in a fully automatic glass surface defect detection machine. It is used in a fully automatic glass surface defect detection machine, which includes a machine platform and a carrier. The backlight source assembly and the carrier are both installed on the machine platform, and the backlight source assembly is located above the carrier. The machine platform is provided with a backlight source position adjustment mechanism for driving the backlight source assembly to move up and down to move away from or close to the carrier. The utility model can be used to illuminate the front of the glass to be detected by setting the backlight source assembly, so that the entire glass to be detected can be clearly presented in the field of view of the CCD camera to improve the reliability and accuracy of the detection. At the same time, the projection illumination range of the backlight source assembly can be adjusted to meet the illumination requirements of the glass to be detected of different specifications and sizes. It has high flexibility of use and meets practical applications, but the scope of application is limited to glass surface defect detection equipment.

[0004] In view of the above problems, the utility model provides a simple backlight source position adjustment mechanism. Utility Model Content
