All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
as shown in fig. 1 to 3, the invention provides a lens edge crush detection device for lens assembly, which comprises a conveying device 1 for conveying lenses and a synchronous detection device 2 arranged on the conveying device 1, wherein a detection camera 3 for detecting the surface of the lenses is arranged on the synchronous detection device 2, and the detection camera 3 moves synchronously with the lenses through the synchronous detection device 2 and collects multi-angle image information in real time for comparison detection;
When the device is used, the lenses are conveyed by the conveying device 1, the lenses are arranged on the conveying device 1 at equal intervals and pass through the synchronous detection device 2 and the lower part of the detection camera 3, and the image information acquired by the detection camera 3 is compared and detected, so that the real-time detection of the lenses in the production and transportation process is realized, and the problem that the lenses are unqualified in batches is avoided.
Detect camera 3 with the same speed motion of lens under the drive of same speed structure 202, the image information who has avoided detecting camera 3 collection takes place to lengthen and warp and leads to the problem that influences the detection accuracy, secondly adjust the detection angle that detects camera 3 through angle adjustment structure 203, carry out image information collection to the lens from a plurality of angles, avoid leading to the blurred problem that influences the detection accuracy of the image information who gathers because of lens surface light problem, carry out multi-angle detection through single detection camera to the lens simultaneously, avoid using a large amount of detection cameras to lead to the problem of wasting of resources.
Further, in this embodiment, the conveying device 1 may be a conveying belt or other devices, and it is sufficient to realize uniform speed conveying of the lenses.
Further, when the detection angle of the detection camera 3 is adjusted, a certain interval is provided for cleaning the image information of the acquisition lens every time the angle is adjusted.

When the same-speed structure 202 is used, the horizontal distance between the two threaded connection seats 206 is at the maximum, that is, one of the threaded connection seats 206 is located at the end of one of the synchronous screws 205, and the other threaded connection seat 206 is located at the end of the other synchronous screw 205 and located at both sides of the central connecting line of the two synchronous screws 205.
When the lens is located at a position right below one of the detection cameras 3, the two first driving devices are simultaneously started to drive the corresponding synchronous screw rods 205 to rotate, and the synchronous screw rods 205 drive the two threaded connecting seats 206 to move towards opposite directions at the same speed through threaded engagement.
One of the detection cameras 3 moves with the same direction and the same speed as the lens and collects image information for comparison and detection, the other detection camera 3 moves with the same speed and the same direction as the lens and does not work, and the detection camera 3 does not work.
When the two threaded connection seats 206 move to the other end of the corresponding synchronous screw 205, the detection camera 3 for detecting the lens stops working, the other detection camera 3 which does not work detects that the next lens is located at the lower position to start collecting image information, and meanwhile, the two first driving devices simultaneously drive the two synchronous screws 205 to rotate in opposite directions, so that the detection action is repeated.

When the detection angle of the detection camera 3 is adjusted, the third driving device is started to drive the linear screw 212 to rotate, the linear screw 212 drives the sliding column 213 to slide along the linear groove 210 through thread engagement, meanwhile, the sliding column 213 slides along the inside of the strip-shaped groove 214, and the strip-shaped block 211 is driven to rotate around the rotating shaft, so that the mounting seat 215 at the bottom of the strip-shaped block 211 makes a circular motion, and the detection angle of the detection camera 3 changes.
Through the motion of sharp screw rod 212 drive slip post 213, can guarantee the stability that detects camera 3 angle modulation through helicitic texture's auto-lock nature, secondly adjust the detection angle that detects camera 3 through slip post 213, make slip post 213 back and forth movement make and detect camera 3 around a plurality of lenses of the reciprocal rotation of rotation and carry out repeated detection through third drive arrangement's positive and negative drive, guarantee the uniformity that detects. A
Further, when the sliding column 213 is located in the middle of the linear groove 210, the detection angle of the detection camera 3 is vertically downward, so that image information is collected on two sides of the lens in the vertical direction during angle adjustment of the detection camera 3, and the detection result is more accurate.
