DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a cutting device for a plano-convex lens, comprising a base 1, a cutting machine 2 and a bearing platform 3, wherein the cutting machine 2 comprises a cutting motor and a rotating cutter 21 fixedly connected to an output shaft of the cutting motor, and the base 1 serves to bear and support the device.

[0024] In this technical solution, a transverse slider 4 is provided on the top of the base 1. The transverse slider 4 can slide horizontally along the base 1. Further, two support plates 11 are welded on the base 1. A lower lead screw 102 that is rotationally connected between the two support plates 11 and is threadedly engaged with the transverse slider 4 is provided. When the lower lead screw 102 rotates, it will drive the transverse slider 4 to move horizontally. The top of the transverse slider 4 is rotationally connected to a bearing platform 3. The function of the bearing platform 3 is to support the lens holder for installing the plano-convex lens raw material. The bearing platform 3 can be set to a profiling structure for placing the plano-convex lens. For example, a concave surface is provided on the bearing platform 3. Since the lens holder and the connection method between it and the bearing platform 3 are prior arts, they will not be described in detail in this embodiment. When the bearing platform 3 rotates, the plano-convex lens raw material placed on it will rotate accordingly. Among them, a power chamber 41 is provided inside the transverse slider 4. A control motor 9 is fixedly provided in the power chamber 41. A bearing shaft 31 is welded to the bottom of the bearing platform 3. The bottom of the bearing shaft 31 penetrates into the power chamber 41 and is fixedly connected to the output shaft of the control motor 9. The control motor 9 provides driving force for the rotation of the bearing platform 3.

[0025] Further, a pressing assembly 6 located above the bearing platform 3 is fixedly connected to one side of the transverse slider 4 through a connecting frame 5. The function of the pressing assembly 6 is to squeeze the middle part of the lens holder or the plano-convex lens raw material on the bearing platform 3, so that the plano-convex lens raw material is in a stable state.

[0026] Specifically, the connecting frame 5 is in a U-shaped structure. The pressing assembly 6 includes an upper lead screw 61 and a pressing plate 63. A nut sleeve 51 sleeved on the upper lead screw 61 is welded to the top of the connecting frame 5. The top of the pressing plate 63 is rotationally connected to the bottom of the upper lead screw 61. The pressing plate 63 is coaxial with the bearing shaft 31. When the upper lead screw 61 rotates forward and backward, the pressing plate 63 can be controlled to squeeze and move away from the plano-convex lens.

[0027] A support 7 near the outer edge is fixedly connected to the top of the base 1. A longitudinal slider 8 is provided on the support 7. Further, two positioning plates 71 are welded to the top of the support 7. A side lead screw 103 that is rotationally connected between the two positioning plates 71 and is threadedly engaged with the longitudinal slider 8 is provided. When the side lead screw 103 is controlled to rotate, the longitudinal slider 8 can be driven to move longitudinally. The cutting machine 2 is fixedly provided on the top of the longitudinal slider 8. The longitudinal slider 8 can slide longitudinally along the base 1. Specifically, the bottom of the cutting motor on the cutting machine 2 is fixedly connected to the top of the longitudinal slider 8. The rotary cutter 21 on the cutting machine 2 is close to the bearing platform 3. Thus, by controlling the sliding of the transverse slider 4 and then controlling the sliding of the longitudinal slider 8, it is convenient to adjust the position of the cutting point of the rotary cutter 21 and the plano-convex lens raw material. After the position is adjusted, the bearing platform 3 is controlled to rotate, and then the cutting machine 2 is started. At this time, the rotary cutter 21 can directly perform profiling cutting.

[0028] In this embodiment, a protective rubber pad 631 is bonded to the bottom of the pressure plate 63. The protective rubber pad 631 can be made of a silicone pad, which can effectively prevent the pressure plate 63 from scratching the plano-convex lens.

[0029] In this embodiment, the free end at the top of the connecting frame 5 is fixedly connected to a water spray pipe 104 through a suspension rod 52. The water inlet of the water spray pipe 104 is connected to an external water supply system through a pipeline. The water spray pipe 104 sprays water to the cutting area to cool it down and flush away the chips. The inner side of the vertical pole on the connecting frame 5 is fixedly connected to a fan 101. The function of the fan 101 is to supply air to the cutting area to supply air to the plano-convex lens and the rotating cutter 21 for heat dissipation.

[0030] Working principle: When in use, first place the plano-convex lens raw material on the external lens frame, then connect the lens frame and the supporting platform 3, then control the upper screw 61 to rotate, and the protective rubber pad 631 at the bottom of the pressure plate 63 squeezes the middle part of the top of the plano-convex lens raw material, and then control the lower screw 102 to rotate to adjust the horizontal position of the plano-convex lens, and then control the side screw 103 to rotate to adjust the entry point of the rotary cutter 21 and the plano-convex lens raw material. After the adjustment is completed, start the cutting machine 2, and the rotary cutter 21 rotates to cut the plano-convex lens. Then start the control motor 9 to drive the supporting platform 3 to rotate at a low speed. The rotary cutter 21 can directly cut out a circular plano-convex lens, which has the advantage of continuous molding processing.

[0031] 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.
