Description

Technical Field

[0001] This utility model relates to the field of optical lens inspection technology, and in particular to an appearance inspection device for optical lens production. Background Technology

[0002] Optical lenses generally refer to optical glass lenses. Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent the glass block from developing internal stress. The cooled glass block must be measured by optical instruments.

[0003] In the prior art, patent CN 218629513 U discloses a testing platform for optical lens production. During use, pressing down on the lowering rod causes the transmission rack of the lowering rod to mesh with the transmission teeth on the side of the rotating wheel, driving the rotating wheel to rotate. This, in turn, causes the upper push rod on the other side to rise. The upper push rod passes through the ejection opening and ejects the optical lens that has completed testing from the testing slot. At this time, the operator can easily remove the optical lens. However, the operation of picking up and putting down the optical lens must be done by the operator, which is cumbersome, time-consuming and labor-intensive, thus reducing the efficiency of testing.

[0018] Please see Figure 1-3 This embodiment provides a technical solution: an appearance inspection device for optical lens production, including a frame 1, a PLC controller 2 mounted on the side of the frame 1, a test platform 7 rotatably connected to the base of the frame 1 via a rotating shaft 6, a drive mechanism 5 for driving the rotating shaft 6 to rotate mounted on the base of the frame 1, placement slots 9 evenly distributed on the test platform 7, a receiving source 8 and a transmittance measuring instrument 10 mounted on the frame 1 corresponding to the placement slots 9, and the receiving source 8 and the transmittance measuring instrument 10 are arranged vertically correspondingly, a position adjustment mechanism 3 mounted on the top of the frame 1, an optical lens picking and placing unit 4 mounted on the adjustment part of the position adjustment mechanism 3, the PLC controller 2 being electrically connected to an external power supply, and the receiving source 8 and the transmittance measuring instrument 10 being electrically connected to the PLC controller 2.

[0019] The drive mechanism 5 includes a stepper motor 51, a stand 52, a worm gear 53, and a worm wheel 54. Two stands 52 are provided, both fixed to the base of the frame 1. The worm gear 53 is rotatably mounted between the two stands 52. The worm wheel 54 is sleeved and fixed on the rotating shaft 6, and the worm gear 53 meshes with the worm wheel 54. The stepper motor 51 is mounted on the side of one of the stands 52. The output shaft of the stepper motor 51 is fixedly connected to the end of the worm gear 53. The stepper motor 51 is electrically connected to the PLC controller 2. The output shaft of the stepper motor 51 drives the worm gear 53 to rotate, and the worm gear 53 meshes with the worm wheel 54. The worm wheel 54 drives the inspection table 7 to rotate via the rotating shaft 6, thereby moving the optical lens to the position corresponding to the receiving source 8 and the transmittance meter 10. Then, the optical lens is subjected to appearance inspection by the receiving source 8 and the transmittance meter 10. The inspection principle is the same as that in the patent with publication number CN 218629513 U, which facilitates continuous inspection operations, thereby improving inspection efficiency.

[0020] The position adjustment mechanism 3 includes an electric push rod 31 and a lifting frame 32. The electric push rod 31 is mounted on the top of the frame 1, and the lifting frame 32 is fixed to the telescopic end of the electric push rod 31. The electric push rod 31 is electrically connected to the PLC controller 2. The position adjustment mechanism 3 also includes a servo motor 35, a gear 36, and a rack 34. The servo motor 35 is mounted on the side of the lifting frame 32, and the gear 36 is fixed on the output shaft of the servo motor 35. The gear 36 meshes with the rack 34. The servo motor 35 is electrically connected to the PLC controller 2. The controller 2 and the position adjustment mechanism 3 also include a guide rod 33, the end of which is fixedly connected to the lifting frame 32. The rack 34 is slidably connected to the guide rod 33. The optical lens picking and placing unit 4 includes a vacuum suction cup 41, a suction tube 42, and a vacuum pump 43. Both the vacuum suction cup 41 and the vacuum pump 43 are installed at the bottom of the rack 34. There are two vacuum suction cups 41, which are fixed at the bottom of the rack 34 near the end. The vacuum pump 43 is connected to the vacuum suction cup 41 through the suction tube 42 and is electrically connected. Connected to PLC controller 2, vacuum pump 43 provides vacuum suction force to vacuum suction cup 41 through suction pipe 42. The vacuum suction cup 41 adsorbs and fixes the optical lens. The telescopic end of electric push rod 31 drives lifting frame 32 to move up and down, thereby adjusting the working height of vacuum suction cup 41, so that it can pick up or put down the optical lens. The output shaft of servo motor 35 drives gear 36 to rotate. Gear 36 meshes with rack 34. Rack 34 slides along guide rod 33, thereby adjusting the lateral working position of vacuum suction cup 41, so that vacuum suction cup 41 can move between the inspection table 7 station, the material picking area and the material placement area. After inspection, the optical lens continues to move to a position that is easy for optical lens picking and placing unit 4 to grasp. Then, position adjustment mechanism 3, together with optical lens picking and placing unit 4, removes the inspected optical lens and places it in the corresponding area. It is convenient for loading and unloading optical lenses, avoids the trouble of manual operation, saves time and effort, and improves inspection efficiency.

[0021] The working principle of the appearance inspection equipment for optical lens production provided by this utility model is as follows: Vacuum pump 43 provides vacuum suction force to vacuum suction cup 41 through suction pipe 42, thereby adsorbing and fixing the optical lens through vacuum suction cup 41. The telescopic end of electric push rod 31 drives lifting frame 32 to move up and down, thus adjusting the working height of vacuum suction cup 41, allowing it to pick up or put down the optical lens. The output shaft of servo motor 35 drives gear 36 to rotate. Gear 36 meshes with rack 34, and rack 34 slides along guide rod 33, thereby adjusting the lateral movement of vacuum suction cup 41. The working position is adjusted so that the vacuum suction cup 41 can move between the inspection table 7 station, the material picking area and the material placement area. The optical lens to be inspected is placed in the placement slot 9 on the inspection table 7. Then, the output shaft of the stepper motor 51 drives the worm gear 53 to rotate. The worm gear 53 meshes with the worm wheel 54. The worm wheel 54 drives the inspection table 7 to rotate through the rotating shaft 6, thereby moving the optical lens to the position corresponding to the receiving source 8 and the transmittance measuring instrument 10. Then, the optical lens is inspected by the receiving source 8 and the transmittance measuring instrument 10. The inspection principle is the same as that in the patent with authorization publication number CN 218629513 U. After the inspection is completed, the optical lens continues to move to a position that is easy for the optical lens picking and placing unit 4 to grasp. Then, the position adjustment mechanism 3 cooperates with the optical lens picking and placing unit 4 to remove the inspected optical lens and place it in the corresponding area.
