The operating tables 24 are all arranged on the upper end of the frame body 231, and the processing mechanism 2 is arranged on the operating table 24.

[0031] Referring to Figure 2As shown in the figure, the lens 3 to be processed includes a lens body 32 and a handle 31 integrally formed at its top end. The end face where the lens body 32 is connected to the handle 31 is a curved surface, and the surface type can be spherical, aspherical, quadratic surface, free surface, etc. The special feature of this lens processing is that the end face of the lens body 32 connected to the handle 31 is not a plane and has a specific surface type. To meet the processing requirements, the processing mechanism 22 uses a profiling tool to cut the handle. The surface type of the surface of the profiling tool in contact with the lens 3 is the same as the surface type of the end face of the lens 3, so that through the control of the cutting process, the surface type and appearance of the handle cutting surface meet the requirements. The lens 3 to be processed is a semi-finished lens, and by cutting off the handle 31, a finished lens is obtained.

[0032] Refer to Figure 3 As shown in the figure, the processing mechanism 22 includes a shearing mechanism 41, a handle receiving mechanism 42, a translation mechanism 43, and a start button 44. The start button 44 is fixed beside the front end of the operating table 24.

[0034] Refer to Figure 5 As shown in the figure, the pneumatic cutter 55 includes a pneumatic cutter body 61 and a profiling hot cutter head 62. The profiling hot cutter head 62 is fixed at the driving end of the pneumatic cutter body 61. The profiling hot cutter head 62 has an openable and closable shearing part, which can be opened and closed horizontally to cut off the handle 31 connected to the top end of the lens body 32.

[0035] Refer to Figure 6As shown, the translation mechanism 43 includes a translation cylinder 71, a profiling jig 72, a mounting bracket 73, a translation slider 74, and a translation slide rail 75. The translation cylinder 71 is fixed to the mounting bracket 73. Two translation slide rails 75 are horizontally and symmetrically fixed to the upper end of the operation table 24. The translation slider 74 is arranged at the bottom end of the profiling jig 72 and is installed on the translation slide rail 75 through sliding fit. The profiling jig 72 is driven by the translation cylinder 71 to move horizontally back and forth.

[0036] Referring to Figure 7 As shown, the profiling jig 72 includes a clamping cylinder 81, a profiling mounting groove 82, a jig support frame 83, and a fixture 84. A groove is provided in the center of the jig support frame 83. Two clamping cylinders 81 are horizontally arranged in this groove. A fixture 84 is arranged at the end of each clamping cylinder 81. Two profiling mounting grooves 82 corresponding to the positions of the clamping cylinders 81 are arranged on the outer edge of the groove on the jig support frame 83 for placing the lens 3. The fixture 84 clamps the lens 3 in the profiling mounting groove 82.

[0037] Referring to Figure 8 As shown, the blank collecting handle mechanism 42 includes a blank handle guide pipe 91, a blank handle collecting box 92, a guide pipe lifting cylinder 93, and a sliding assembly 94. The driving end of the guide pipe lifting cylinder 93 is connected to the upper end of the sliding assembly 94. The blank handle guide pipe 91 is vertically fixed to the front end of the sliding assembly 94. The sliding assembly also uses a slider and a vertical guide rail in the prior art. The blank handle collecting box 92 is arranged below the blank handle guide pipe 91. The upper end of the blank handle guide pipe 91 is connected to the opening provided on the operation table 24, and the lower end is arranged in the blank handle collecting box 92.

[0038] When the optical lens blank processing device of the present utility model is in use, an operator places the lens 3 to be processed into the profiling mounting groove 82 and presses the start button 44, and the device enters the automatic processing state.

[0039] The two clamping cylinders 81 act to drive the fixture 84 to clamp the lens 3 in the profiling mounting groove 82. Then the translation cylinder 71 acts to drive the entire translation mechanism 43 to move horizontally back and forth on the translation slide rail 75, moving the profiling jig 72 from the loading position to the processing position.

[0040] The shearing mechanism 41 uses the upper and lower cylinders 51 of the cutter to drive the pneumatic cutter 55 to move up and down. During the movement, the guide sleeve 52 is set on the sliding column 56 through a sliding fit, so that the pneumatic cutter mounting plate 54 between the guide sleeves 52 moves smoothly, and the lowering of the pneumatic cutter mounting plate 54 is limited by the limiting column 53, so that the profiling hot cutter head 62 just moves to the action position, and the position to be processed in the transition area between the lens body 32 and the material handle 31 is hot cut. The profiling hot cutter head 62 is made according to the outer contour of the lens 3 and is installed on the pneumatic cutter body 61. In the above-mentioned hot cutting process, the profiling hot cutter head 62 opens and closes horizontally, thereby realizing the cutting of the material handle 31. The material handle cutting surface of the lens 3 is a curved surface, which is consistent with or close to the surface shape of the top of the lens 3.

[0041] After the hot cutting is completed, the pneumatic cutter body 61 remains stationary, the cutter upper and lower cylinders 51 return to the original position, and the translation cylinder 71 moves back to the loading position. The material collecting handle mechanism 42 starts to recycle waste materials. The guide tube lifting cylinder 93 moves from the original position to the working position, driving the material handle guide tube 91 to rise to the bottom of the profiling hot cutter head 62, and the pneumatic cutter body 61 moves to open the profiling hot cutter head 62, and the material handle 31 falls into the material handle collection box 92 through the material handle guide tube 91. At this point, the lens processing is completed.

[0042] The whole process is completed after the processed lens body 32 is taken out from the profiling fixture 72 in the translation mechanism 43 at the loading position manually. The loading and unloading are repeated, and the equipment runs continuously to realize batch processing of the lenses 3, so that the lenses and the material handles can be automatically separated, thereby improving the processing efficiency of the lenses and improving the processing quality.

[0043] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
