[0003] In the scenario of optical lens fine grinding, the in-process online automatic repair R precision mechanism system of the traditional grinding push-pull machine uses a servo motor to drive an eccentric wheel and a front rod, and realizes grinding through the movement of points A, B, and C. Among them, point C is the mechanical origin, and points A and B are moving points, corresponding to the diameter of the product to be processed. During the operation of using this machine, it is necessary to manually adjust the eccentric wheel and the front rod to match products of different sizes, resulting in a cumbersome process, high technical requirements for operators, and the need for skilled technicians to monitor in real time during the processing to adjust the processing angle to control the defective product rate. This not only increases the labor cost but also reduces the production efficiency. Moreover, frequent manual adjustment and monitoring are required during the operation, and it is difficult for traditional equipment to achieve multi-task parallel processing, which limits the improvement of production efficiency and production capacity. In addition, traditional equipment lacks a real-time monitoring and feedback mechanism, and the grinding accuracy depends on the experience of operators, making it difficult to ensure processing consistency and prone to producing defective products.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Referring to 1- Figure 5 , an optical lens precision grinding and polishing push-pull machine, including a base 1, at least two processing grooves 2 are opened at the top of the base 1, and at least one fixing mechanism for placing optical lenses is provided at the bottom of the processing groove 2, and more than one optical lens can be placed simultaneously and the processing operation can be completed.

[0020] Among them, as Figure 2 and Figure 3As shown, a chamber is provided inside the base 1. The front projection of the chamber is located below the processing groove 2. The fixing mechanism includes a suction cup 3. During actual use, the suction cup 3 is a pneumatic suction cup. The suction cup 3 is arranged at the bottom inside the processing groove 2. An annular bearing seat 4 is installed on the top output end of the suction cup 3. A rubber ring for buffering and providing sealing for the optical lens placed thereon is installed on the top of the bearing seat 4. And a pushing member 6 is connected to the bottom of the suction cup 3. The pushing member 6 is arranged inside the chamber. During actual use, the pushing member 6 is one of an electric push rod, a cylinder, and a hydraulic cylinder. Thus, after the optical lens is placed on the bearing seat 4, the optical lens will be adsorbed and fixed by the suction cup 3. Subsequently, the pushing member 6 can drive the optical lens to move up and down inside the processing groove 2, facilitating the placement and removal of the optical lens. And above the processing groove 2, there is an installation frame 8 corresponding to the fixing mechanism one by one. A grinding device for precisely grinding the optical lens is installed at one end of the installation frame 8 close to the fixing mechanism. The pushing member 6 will push the optical lens close to the grinding device for processing.

[0021] During the processing, in order to ensure the accuracy of the grinding process, a first laser rangefinder 5 is provided in the middle of the bearing seat 4. The first laser rangefinder 5 is fixed to the inner wall of the bearing seat 4 through a bracket. The distance feedback of the light beam emitted by the first laser rangefinder 5 through the lens acting on the grinding device can be obtained, and the position of the grinding device corresponding to the lens can be obtained, so as to facilitate adjusting the acting position of the grinding device on the lens during grinding.

[0022] As Figure 4 and Figure 5 As shown, a moving seat 9 is installed at the top of the other end of the installation frame 8. The moving seat 9 is threadedly connected to the lead screw 10 through a nut. And the lead screw 10 is arranged inside a fixing frame 11 with the end bent downward in an "L" shape. And the end of the lead screw 10 is rotatably connected to the fixing frame 11. Among them, one end of the fixing frame 11 away from the installation frame 8 is fixed to the installation seat 12. The installation seat 12 is fixed to the support plate 13. And the support plate 13 is fixed to the base 1. A driving motor 14 for driving the lead screw 10 to rotate is connected to the end of the lead screw 10 away from the installation frame 8. Under the rotation of the lead screw 10, the installation frame 8 can be controlled to move linearly, so as to adjust the corresponding position of the grinding device on the lens, so as to process lenses of different sizes.

[0023] And in order to precisely control the linear movement of the installation frame 8, a second laser rangefinder 20 is installed on one side of the installation seat 12 close to the installation frame 8. The second laser rangefinder 20 corresponds to the installation frame 8.

[0024] Further, at one end of the mounting bracket 8 close to the mounting base 12, at least one cylindrical guiding groove 18 is formed, and a guiding shaft 19 is arranged inside the guiding groove 18. The other end of the guiding shaft 19 is fixed to the mounting base 12 to guide the linear movement of the mounting bracket 8, so as to improve the stability of the mounting bracket 8 during movement, avoid deviation or vibration, and ensure the grinding uniformity.

[0025] Among them, the driving motor 14 is arranged inside the motor box 15, and the motor box 15 is fixed to the support plate 13. The output end of the driving motor 14 penetrates through the motor box 15 and is rotatably connected therewith, so as to protect the driving motor 14 and prevent an object from falling on the driving motor 14 and colliding with the driving motor 14, thereby causing damage to the driving motor 14. In actual use, the motor box 15 is composed of a heat sink plate, and ventilation openings are further formed on the side wall of the motor box 15 to dissipate heat from the driving motor 14.

[0026] In order to facilitate the maintenance and repair of the driving motor 14, an opening 16 is formed on one side of the motor box 15 away from the lead screw 10, and an opening and closing door 17 is arranged on the opening 16. One side of the opening and closing door 17 is hinged to the motor box 15, and the other side of the opening and closing door 17 is connected to the motor box 15 through a lock.

[0027] The present invention further includes a control cabinet 21, which is located above the base 1, and the bottom of the control cabinet 21 is fixed to the base 1 through a support frame 22. Controllers corresponding to the grinders are arranged inside the control cabinet 21. Each controller is connected to its corresponding grinder, pushing member 6, suction cup 3, first laser rangefinder 5, second laser rangefinder 20, and driving motor 14 through wires. In actual use, the controller is one of a PLC logic controller, a control main board, and a control host, realizing programmed control, without manual adjustment of moving points. After the product inputs parameters for the first time, subsequent processing can be carried out with one key.

[0028] Specifically, a display 23 and control buttons 24 corresponding to the mounting brackets 8 one by one are installed on one side of the control cabinet 21 close to the processing tank 2. The display 23 and the control buttons 24 are both connected to the corresponding controller through wires. The control cabinet 21 integrates multiple controllers, and in cooperation with the display 23 and the control buttons 24, the processing parameters can be monitored and adjusted in real time, improving the operation convenience.

[0029] It should be noted that a storage tank 7 is arranged on one side of the base 1 close to the processing tank 2. The arrangement of the storage tank 7 facilitates the temporary placement of tools or lenses, improving the work efficiency.

[0030] As described above, it is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto.
