Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to an optical lens grinding and grasping manipulator. Background Art

[0002] Optical lenses are transparent materials made from optical materials such as glass or resin, and are commonly used in eyeglasses to correct vision and provide a clear field of view. Optical lens polishing involves a series of processing steps to remove surface irregularities, burrs, and minor defects, resulting in a smoother surface and improving the clarity and precision of optical imaging.

[0003] In the existing technology, after the optical lens is processed, it is generally transported out through a conveyor belt. Then, a mechanical gripper picks up the lens on the conveyor belt and places it into the processing window of the grinder. After the grinding is completed, the mechanical gripper sends the lens to the surface inspection device for appearance inspection. After the inspection is completed, the staff will take out and classify the lens. The whole set of operation procedures is relatively cumbersome, and it takes a certain amount of time between the completion of grinding and the inspection. The work efficiency needs to be further improved. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 3 The figure shows the entire structure of the optical lens grinding and grasping manipulator of the present invention. Figure 1-Figure 3 In this embodiment, an optical lens grinding and grasping robot includes an electric rail platform 100, an electric slide 200 is slidingly provided at the upper end of the electric rail platform 100 along its length direction, a first telescopic electric cylinder 300 is horizontally arranged at the upper end of the electric slide 200, an extension plate 400 is fixed to one side of the electric slide 200, a second telescopic electric cylinder 500 is provided at the upper end of the extension plate 400 and is on the same horizontal line as the first telescopic electric cylinder 300, and a rotating seat 600 for driving the second telescopic electric cylinder 500 to rotate horizontally, the outer ends of the output shafts of the first telescopic electric cylinder 300 and the second telescopic electric cylinder 500 are provided with independent lifting assemblies 700 and a clamp 800 driven by the lifting assemblies 700 to move up and down.

[0022] The top surface of the electric rail platform 100 is also provided with a slide groove 110 along its length. The bottom of the extension plate 400 is provided with sliders 410 on both sides, which slidably mate with the slide groove 110. It is understood that the cooperation between the sliders 410 and the slide groove 110 effectively improves the operational stability and smoothness of the extension plate 400 and the electric slide 200, facilitating precise grasping by the manipulator. The rotating base 600 comprises a fixed cylinder 610 fixed to the upper end of the extension plate 400, a turntable 620 horizontally rotatably mounted on the top of the fixed cylinder 610 via bearings, and a servo motor 630 disposed inside the fixed cylinder 610, with its output end coaxially connected to the bottom of the turntable 620. It is understood that the second telescopic cylinder 500 is fixedly mounted on the top of the turntable 620. The servo motor 630 drives the turntable 620 to rotate, thereby driving the horizontal rotation of the second telescopic cylinder 500. The lifting assembly 700 includes a fixed plate 710 fixed to the output end of the first telescopic cylinder 300 or the second telescopic cylinder 500, positioning sleeves 720 fixed to both ends of the fixed plate 710, a guide rod 730 that slides vertically through the inner side of the positioning sleeve 720, a base plate 740 fixedly connected to the bottom of the guide rod 730, and a cylinder 750 mounted on the upper end of the fixed plate 710 with its bottom output shaft connected to the top of the base plate 740. A clamp 800 is mounted on the bottom of the base plate 740. It should be noted that the clamp 800 used to clamp the optical lens can be a suction cup or a pneumatic clamp, etc., and can be installed or replaced according to actual needs. The coordination of the lifting assembly 700 makes the clamp 800 more linear and stable during its up and down movement, which facilitates the precise grasping of the lens. Specifically, in this embodiment, the electric slide 200 first drives the first telescopic electric cylinder 300 to move to the raw material station near the mounting plate 900, and the lens to be polished is clamped by the extension of the electric cylinder and the cooperation of the lifting component 700 and the clamp 800 and returned to the polishing station under the drive of the electric slide 200, and then the lens is sent to the station in the polishing window for polishing. After the polishing is completed, the first telescopic electric cylinder 300 will return to the raw material station. During this process, the second telescopic electric cylinder 500 will follow and move to the polishing station under the drive of the extension plate 400 and the electric slide 200, and use the electric cylinder The polished lens is taken out by telescopic movement with the cooperation of the lifting assembly 700 and the clamp 800. At this time, the output end of the first telescopic electric cylinder 300 has also clamped the lens to be polished. Then the two telescopic electric cylinders return synchronously. At this time, the first telescopic electric cylinder 300 sends the lens to be processed to the polishing station, and the second telescopic electric cylinder 500, driven by the rotating seat 600, will rotate to 180° or a specific angle, and the telescopic electric cylinder will send the polished lens to the appearance inspection station, so that the feeding, unloading and inspection feeding are synchronized, which effectively simplifies the robot transmission process and further improves the polishing, grasping and work efficiency.

[0023] Furthermore, a mounting plate 900 is provided at one end of the upper portion of the electric rail platform 100, and a laser rangefinder 910 is provided on the side of the mounting plate 900 facing the electric slide 200. It is understood that in order to more accurately control the reciprocating travel of the electric slide 200 and the manipulator, the displacement of the electric slide 200 can be corrected in real time under the measurement of the laser rangefinder 910 and in coordination with the control system, which is conducive to the stable operation of the manipulator.

[0024] Furthermore, the upper end of the electric slide 200 includes a positioning base for supporting and mounting the first telescopic cylinder 300. As will be appreciated, since the second telescopic cylinder 500 is elevated by the rotating base 600, the positioning base allows the first telescopic cylinder 300 to be positioned flush with the second telescopic cylinder 500, facilitating integrated control of the manipulator by the control system.
