Embodiment Construction
[0049] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0050] refer to Figure 1 to Figure 4 , the present invention provides a method for using lens MTF automatic detection and sorting equipment, step S001, placing the trays; taking a plurality of trays 9, and putting a part of the trays 9 into the sorting device arranged on one side of the workbench 1 4; then place the lens to be tested in another part of the material tray 9, and then put the material tray 9 full of the lens to be tested into the feeding device 2 that is arranged near the sorting device 4;
[0051] Step S002, feeding; the feeding tray 7 of the feeding device 2 drives the feeding tray 9 filled with the lenses to be tested to slide to the bottom of the convey...

The invention provides a using method of lens MTF automatic detection and sorting equipment. The using method comprises the following steps that S001, a material disc is placed; Step S002, feeding is carried out; a feeding tray drives the material disc filled with to-be-tested lenses to slide to the position below a carrying device; S003, the materials are taken and placed; the carrying device sucks a single lens in the material disc and conveys the single lens to an MTF detection device for detection, sucks the detected lenses in the MTF detection device and conveys the detected lenses to a sorting device for sorting; s004, MTF detection is carried out; the MTF detection device detects the to-be-detected lenses to obtain MTF information of the lenses; S005, sorting is carried out; and the sorting device judges the quality of the detected lenses according to the detection result of the MTF detection device, sorts the detected lenses and puts the detected lenses into an empty material disc. According to the using method of the lens MTF automatic detection and sorting equipment, the defects that existing lens detection is low in efficiency and yield and large in labor intensity are overcome.
Description
technical field [0001] The invention relates to the field of lens detection, in particular to a method for using a lens MTF automatic detection and sorting device. Background technique [0002] MTF refers to the universal modulation transfer function, which is the main test method used to evaluate the resolution and performance of the optical system, and is an important auxiliary means for the objective evaluation of the image forming ability of the optical system. With the development and progress of science and technology, MTF detection technology has been widely used in the field of electronics, especially the detection of lenses in electronic products. [0003] At present, the existing lens inspection method is: put the lens into the MTF testing machine by manual feeding, the MTF testing machine will measure the MTF of the lens and judge the result, and then reflect the lenses of four specifications and colors on the display screen Finally, according to the different co...
