Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] See also Figures 1 to 6 As shown. The embodiment of the utility model proposes a detection equipment platform for detecting lenses based on a detection instrument. The main protection requested is a device hardware structure layout. The electric control system and software control part on the device are not described in detail in this application. Those skilled in the art are fully capable of completing the design of the electric control and software system parts based on the hardware layout of this application. The main detection device - the detection instrument is also a standard part purchased from the market. It includes a body 1, which has an outer frame, a window and an internal space. The electric control box component of the device is placed at the bottom of the body. The outer frame and window of the body are based on conventional design and play a protective role when the device is working normally. In this embodiment, the applicant hides the body window in order to show the internal structure of the device in detail.

[0031] According to different testing requirements, the testing instrument may be different, that is, the testing instrument is not a single and unchanging one. In this embodiment, a Fizeau interferometer is used to detect the surface quality of the lens; of course, the Fizeau interferometer can also be replaced by a mirror locator to detect the relative position of the lens surface, such as the mirror spacing, lens center thickness, optical path difference, etc.; the Fizeau interferometer can also be replaced by a spherometer to detect the spherical curvature radius of the lens. In general, for this application, the type of testing instrument used is not a key technical point. The key lies in the layout design of this application that can automatically detect the quality of the lens.

During the rotation of the lens to be tested, the barcode scanning component 6 reads the coded information for recording and classification. The lens to be tested with the coded information read is then automatically sent by the industrial robot 3 to the detection instrument 2 for testing. After the test is completed, the industrial robot 3 places the lens to be tested in the good product tray station 42 or the defective product tray station 43 of the tray area 4 according to the test results, and then repeats the above steps.

[0036] Three number reading cameras 7 are also arranged above the internal space of the body 1, all of which work vertically downward, corresponding to the tray modules on the loading tray station 41, the good product tray station 42, and the defective product tray station 43 respectively; wherein the tray module includes a plane light source 401 arranged at the bottom, side light sources 402 arranged on the four sides, and a tray 403 arranged at the top.

The number marks are used to distinguish each lens on the tray one by one, so that the industrial robot can perform accurate clamping. In addition, the plane light source can shine upward through the hollow number marks to assist the work of the camera reading the number.

[0038] In addition, four limit blocks 406 are arranged at four corners on the top of the tray module, which are symmetrically distributed. An L-shaped bayonet 407 is formed on the limit block 406, and a positioning pin 408 is formed on the surface of the limit block 406 for matching with the bottom of the tray 403.
