Description

Technical Field

[0001] This utility model relates to the field of spectacle lens processing technology. Specifically, it relates to spectacle lens processing equipment. Background Technology

[0002] With the rapid growth in demand for personalized lens customization, scanning and processing technology for personalized lenses has become a core factor determining lens fitting accuracy and production efficiency. Currently, lens finishing can be categorized into two types based on automation: the first is the traditional manual processing mode. The drawback of this mode is that lens finishing relies entirely on the technician's experience, lacking relevant data support, resulting in a high operational threshold that inexperienced technicians find difficult to master. The second is the fully automated processing mode, which uses automated 3D edging machines for lens finishing. However, these machines operate on preset modes, and domestically produced 3D edging machines cannot meet the personalized lens customization needs of customers due to their low processing accuracy and high failure rate. Imported equipment, on the other hand, is prohibitively expensive for widespread use in optical shops. Therefore, it is necessary to research a lens processing equipment that provides comprehensive data information for personalized lenses, thereby enabling better results in lens customization.

[0038] like Figure 9-11As shown, the exterior finishing section 400 includes a lower water tank 414, an open upper water tank 415 mounted on the lower water tank 414, and a motor mounting base 402 mounted outside the lower water tank 414. The lens 500 clamped by the lens clamping section 300 is located inside the upper water tank 415. The lower water tank 414 is mounted on the base plate 101. The variable speed motor 401 and the rotation angle motor 404 are arranged vertically on the inner side of the motor mounting base 402.

Each tool mounting seat 407 is equipped with a second coupling 411 on its input side.

[0039] A water pump 412 is mounted on the outer side of the motor mounting base 402. A nozzle 413 is provided on the water pump 412. The nozzle 413 is located in the lower water tank 414. The plane where the water outlet of the nozzle 413 is located is on the same plane as the plane where the first coupling 403 is located.

[0040] The lower water tank 414 is equipped with a grating reader 417.

[0041] The working principle of this utility model is as follows:

[0042] 1. Lens clamping and precise positioning process: such as Figure 3-7 As shown, the lens 500 to be processed is placed between the left chuck 302 and the right chuck 304 of the lens clamping part 300. The motor push rod 318 is started to push the chuck seat 303, which in turn pushes the left chuck 302 to move towards the lens, and then the lens 500 is flexibly clamped by the silicone pad 314. The right chuck 304 realizes the angle rotation of the lens 500 through the right rotation shaft 301.

[0043] The servo motor 319 drives the servo motor mounting cylinder 309, causing the lens 500 to rotate around the servo motor axis; the stepper motor 320 drives the mirror axis gear 322 through the synchronous belt 311 to achieve axial angle positioning of the lens 500; then the position of the optical coupler baffle 313 is detected by the mirror axis optical coupler 321 to provide feedback on the rotation angle, thereby determining the radial spatial position and axial spatial angle of the lens 500, providing spatial coordinates for the precision machining of the lens 500.

[0044] The transverse slide 102 drives the transverse mounting base 201 to move along the base bracket 100, and the position is determined by the transverse optical coupler baffle 208 and the transverse optical coupler 107.

[0045] The longitudinal slide 203 drives the vertical moving top plate 205 to move vertically. This drives the positioning screw 206 to lift, which in turn drives the rotating head 308 through the fixed seat. The rotating head 308 moves up and down along the guide rail 212, thereby controlling the longitudinal movement of the lens clamping part 300. The magnetic grating reader 207, in conjunction with the magnetic strip 315, acquires the longitudinal displacement of the machine body in real time, thereby determining the spatial height of the lens 500. The longitudinal optical coupler 209 and the vertical optical coupler baffle 316 work together to determine the longitudinal zero position of the machine body.

[0046] 2. Lens processing, such as Figure 7-9 As shown, after completing the above lens clamping and positioning steps, the variable speed motor 401 is driven, and the tool mounting base 407 is further driven through the first coupling 403 and the second coupling 411 to drive the machining tool to rotate at high speed. Then, the spatial position of the lens 500 is adjusted by controlling the transverse slide 102 and the longitudinal slide 203, so as to further realize the fine machining treatment of the lens 500 such as grooving, chamfering and polishing, and the grooving depth, chamfering width and polishing effect can be controlled.

[0047] Similarly, based on the radial spatial position and axial spatial angle of the lens measured in step 1, the spatial coordinates of the lens are calculated by the algorithm. The rotating angle motor 404 drives the rudder disk 405 to rotate, which in turn drives the tool holder 406 to rotate. According to the set positions of the three sets of tools, the tools are rotated by a specific angle, so that the drilling and milling tool 408, the grooving tool 409 and the chamfering and polishing tool 410 are connected to the first coupling 403 via the second coupling 411, so as to achieve the purpose of changing the machining tools.

[0048] Further adjustments are made to the spatial position of lens 500 in step 1, followed by drilling and edge trimming of lens 500 in step 2. Closed-loop control is achieved using pressure sensor 327. Once lens processing is complete, the positioning screw 206 is raised to contact pressure sensor 327, at which point the pressure data collected by pressure sensor 327 automatically identifies the completion of processing.

[0049] Based on this, by combining the lens curvature radius and edge thickness data, the tool feed speed and cutting force are dynamically adjusted to ensure stable contact between the tool and the lens 500 surface during the machining process; at the same time, the slide position information is fed back in real time through displacement sensors (including encoder reader 108, magnetic scale 213, magnetic scale reader 207 and magnetic strip 315) to form closed-loop control and improve machining accuracy; finally, multi-process continuous automated operation is completed, effectively ensuring the consistency and yield of lens processing.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
