[0096] The automatic testing device comprises:

[0097] A grabbing frame 5 is arranged opposite to the detection frame;

[0098] A grabbing support frame is arranged on the upper portion of the grabbing frame 5;

[0099] Three grabbing mechanical claws 6 are arranged on the outer edge of the grabbing support frame in a circumferential direction and are used for grabbing and carrying the lenses;

[0100] A downward driving member 7 is arranged on the upper end of the grabbing frame 5 and can drive the grabbing support frame to move up and down on the grabbing frame 5;

[0101] A downward rotating driving member 8 is arranged on the lower portion of the grabbing support frame and is used for driving the grabbing support frame to rotate.

[0102] In the technical solution, the grabbing frame 5 is used for supporting the grabbing support frame and has different functions when being located on the feeding conveying line 1, the discharging conveying line 2 and the automatic testing device; when the grabbing mechanical claws 6 are located on the discharging position of the feeding conveying line 1, the lenses on the feeding conveying line 1 are grabbed; when the grabbing support frame drives the grabbing mechanical claws 6 to move the grabbed lenses to the lens detection assembly 4, the grabbed lenses are detected by the lens detection assembly 4; when the detection is qualified, the grabbing support frame drives the grabbing mechanical claws 6 to be located on the discharging conveying line 2, and the grabbed lenses are placed on the discharging conveying line 2. The arrangement of the three grabbing mechanical claws 6 can realize the synchronous operation of grabbing, detecting and placing, thereby greatly shortening the production time. The grabbed lenses are located between the scanning device 4b and the detection device 4c after being grabbed by the grabbing mechanical claws 6.

[0103] The arrangement of the downward driving member 7 can drive the grabbing support frame to move downward, thereby facilitating the grabbing mechanical claws 6 to grab or place the lenses, and can adjust the distance between the lenses and the scanning device 4b, thereby ensuring the detection and grabbing effects. The downward rotating driving member 8 is used for driving the grabbing support frame to rotate, and the angle of rotation of the grabbing support frame is 120° or 60° each time; when the lenses detected by the lens detection assembly 4 are unqualified, the downward rotating driving member 8 drives the grabbing support frame to rotate by 60°, the rear grabbing mechanical claws 6 are loosened, the rear downward rotating driving member 8 drives the grabbing support frame to rotate by 60°, and the grabbing support frame is located at the normal detection position. In this process, the downward driving member 7 is not driven, the grabbing mechanical claws 6 located between the feeding conveying line 1 and the lens detection assembly 4 remain in the state of grabbing the lenses, and the grabbing mechanical claws 6 located between the feeding conveying line 1 and the discharging conveying line 2 are in the state of not grabbing the lenses because the lenses have been placed on the discharging conveying line 2 in the previous operation, so the grabbing mechanical claws 6 can remain in the loosened state.

[0104] The lower pressing driving part 7 can be a hydraulic driving cylinder or a pneumatic cylinder, and a guide rod is arranged on the lower pressing driving part 7 to prevent the grabbing support frame from being deviated during driving.

After the grabbing, placing or detecting is completed, the lower pressing driving part 7 is in a reset state, i.e. the grabbing support frame is raised. The detection frame is provided with a detection plate, and the detection plate is provided with a detection driving part with the detection device 4c lowered. The detection driving part drives the detection device 4c to be lowered when the lens is detected. After the detection is completed, the detection driving part drives the detection device 4c to be raised.

[0131] The outer frame body 11 is formed with three support arms uniformly distributed in a circle, each support arm is provided with a grabbing mechanical claw 6, and a reinforcing rib plate is formed between adjacent support arms;

[0132] The outer rotating cylinder 12 is integrally formed in the middle of the outer frame body 11, coaxially formed with a positioning hole 12a on the outer wall, and provided with a plurality of outer air holes 12b communicating with the positioning hole 12a, a plurality of equidistant annular air grooves 12c are formed on the wall of the positioning hole 12a, and each outer air hole 12b communicates with one annular air groove 12c; and a connecting flange connected with the upper connecting disc is formed at the bottom of the outer rotating cylinder 12;

[0136] The upper air hole 14 and the inner air hole 15 are in communication to form a gas feeding channel, and each gas feeding channel is in communication with an annular air groove 12c, respectively;

[0137] Rotary bearings 16 are arranged between the two ends of the inner positioning cylinder 13 and the positioning holes 12a of the outer rotating cylinder 12.

[0138] In the technical solution, the outer frame body 11 can ensure the structural strength of the whole grabbing support frame, the support arms of the outer frame body 11 facilitate the fixation of the grabbing mechanical claws 6, the reinforcing rib plates can improve the connecting strength between the support arms, and the temperature and stiffness of the whole structure of the outer frame body 11 are ensured.

[0141] The sealing retaining member can ensure the sealing property of the connection between the inner positioning cylinder 13 and the outer rotating cylinder 12, and the end limiting cover 21 can prevent the inner positioning cylinder 13 from being separated from the outer rotating cylinder 12. The rotary bearing 16 can ensure the free rotation of the outer rotating cylinder 12 relative to the inner positioning cylinder 13.
