Technical Field

[0030] Working principle:

[0031] Step 1: Adjust the distance between two adjacent V-shaped step lens placement grooves 21 according to the outer diameter of the lens to be tested, turn the knob 19, the knob 19 drives the bidirectional screw 20 to rotate, and the bidirectional screw 20 drives the two positioning blocks 12 to move closer to each other until the distance between the two V-shaped step lens placement grooves 21 reaches the required distance, and then repeat the above operation until the position adjustment of all V-shaped step lens placement grooves 21 is completed;

[0032] Step 2: The equipment is started, and the external loading mechanical equipment is used for loading. The lens is placed on the steps of two adjacent V-belt step lens placement grooves 21, and the lens is positioned by the positioning block 12 cooperating with the V-belt step lens placement groove 21. Then the first motor 4 starts to run, and the first motor 4 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the main shaft rollers of the two belt conveyors 8 to rotate, thereby driving the two belt conveyors 8 to run. The belt conveyor 8 drives each fixed rod 3 and the outer frame 5 to move through the belt, and the outer frame 5 drives the distance adjustment component connected thereto to move, thereby driving the lens to move until the lens moves to the set position. At this time, the first motor 4 runs intermittently. When the first motor 4 stops running, the external loading mechanical equipment starts the loading operation again, and so on and so forth until the lens moves to the bottom of the sensor 17;

[0033] Step 3: The first spotlight 10, the second spotlight 11 and the sensor 17 start running, the second motor 13 starts running, the second motor 13 rotates forward or reversely, thereby driving the one-way screw 14 to rotate forward or reversely, the one-way screw 14 drives the slide 16 to reciprocate along the fixed seat 15, thereby driving the movable frame 9 to reciprocate, and the movable frame 9 drives the first spotlight 10, the second spotlight 11 and the sensor 17 to reciprocate. At this time, the first motor 4 is in the intermittent operation period in step 2, and the lens can be detected in cooperation (the detection principle of the first spotlight 10, the second spotlight 11 and the sensor 17 has been described in a detection device for optical glass lens production with the prior art publication number CN218331297U);

[0034] Step 4: After the lens that has completed the inspection is moved to the outside of the body 1 and the first motor 4 stops running, the lens is removed by an external unloading mechanical device.

[0035] It should be noted that in the present application, the rotating connection adopts a bearing connection, the inner ring of the bearing is fixedly connected to the movable part, and the outer ring of the bearing is fixedly connected to the fixed part.
