[0027] Example

[0028] Reference Figure 1 - Figure 4 , which is an embodiment of the present utility model, provides a high-precision laser lens processing measuring device, comprising: a support unit 100 and a measuring unit 200;

[0029] The support unit 100 includes a measuring platform 101, a support base 102 fixedly connected to the top of the measuring platform 101, and a curve meter 103;

[0030] The measuring unit 200 includes a rectangular box 201 slidably arranged on the top of the measuring platform 101, and the inner wall of the rectangular box 201 is fixedly connected with two vertically distributed limit rods 202, and the outer walls of the two limit rods 202 are slidably sleeved with a connecting plate 203. A sliding groove that fits the connecting plate 203 is provided on one side of the rectangular box 201, and the top and bottom of the inner wall of the rectangular box 201 are fixedly connected with pressure sensors 204, and springs 205 are fixedly connected between the opposite surfaces of the connecting plate 203 and the two pressure sensors 204. The bottom of the connecting plate 203 is fixedly connected with two support plates 206, and the opposite surfaces of the two support plates 206 are provided with circular grooves. Bearings 207 are inlaid in the circular grooves of the two support plates 206, and the inner walls of the two bearings 207 are fixedly connected with rollers 208.

[0031] The support base 102 is used to place the laser lens. The curvilinear instrument 103 is an instrument that uses a high-precision force sensor to sense changes in force and obtains a completely accurate load curve experiment through computer processing. The technology of the curvilinear instrument 103 is very mature, and its working principle will not be described in detail here. The curvilinear instrument 103 is used to receive the pressure signal of the pressure sensor 204 and convert it into a corresponding curve so that technicians can determine the degree of curvature of the lens surface. Under the action of gravity, the lowest point of the roller 208 is lower than the highest point of the support base 102. By placing a plano-concave mirror or a plano-convex mirror on the support base 102, the curved surface of the lens is vertically upward. Then, the connecting plate 203 is lifted and the rectangular box 201 is moved toward the support base 102 so that the roller 208 is directly above the lens.

[0032] Then, the connecting plate 203 is loosened to allow the roller 208 to contact the lens. At this time, the two pressure sensors 204 are turned on. Then, the rectangular box 201 is moved to allow the roller 208 to roll along the curved surface of the lens. The two bearings 207 enable the roller 208 to roll smoothly and stably. During the rolling process of the roller 208, the roller 208 will drive the connecting plate 203 up and down due to the curved surface. The connecting plate 203 is slidably set in the slide groove of the rectangular box 201. When the connecting plate 203 slides on the two limit rods 202, the connecting plate 203 will squeeze the two springs 205, so that the two springs 205 squeeze the two pressure sensors 204 under the interaction force.

[0033] The two pressure sensors 204 are in a complementary relationship. When the pressure of one increases, the pressure of the other decreases. This allows technicians to calibrate the pressure through the two pressure sensors 204 and provide accurate pressure data to the curve meter 103. The curve meter 103 can then calculate the curvature of the lens surface and roll the roller 208 on the lens, so that the roller 208 does not directly rub against the lens surface, thereby avoiding scratches on the lens.

[0034] In addition, the top of the connecting plate 203 is fixedly connected to a round rod 209 that passes through the connecting plate 203, and the two ends of the round rod 209 are respectively located at the inner center of the two springs 205. The top of the measuring platform 101 is fixedly connected to a fixed plate 210, and one side of the fixed plate 210 is fixedly connected to an electric telescopic rod 211, and the output end of the electric telescopic rod 211 is fixedly connected to one side of the rectangular box 201.

[0035] A gap is left between the round rod 209 and the two pressure sensors 204 to allow the connecting plate 203 to move. The round rod 209 is used to limit the spring 205 so that when the spring 205 is squeezed by the connecting plate 203, the spring 205 can be compressed in a vertical state. The round rod 209 prevents the spring 205 from deflecting during the compression process to ensure the stability of the pressure applied to the pressure sensor 204. The rectangular box 201 is pushed by the electric telescopic rod 211 to save the worker's physical strength, and the electric telescopic rod 211 can drive the rectangular box 201 to move at a uniform speed, so that the roller 208 can contact the lens at a uniform speed and fully.

[0036] Furthermore, an L-shaped plate 212 is fixedly connected to the top of the measuring platform 101 , and a laser pen 213 is fixedly connected to the top of the inner wall of the L-shaped plate 212 .

[0037] The laser of the laser pen 213 can be irradiated vertically onto the support base 102. When the light is irradiated on the concave mirror, the light will converge to the focus of the concave mirror. When the light is irradiated on the convex mirror, the light will diverge outward after being reflected on the surface of the convex mirror. By irradiating the lens with the laser pen 213, the worker can adjust the position of the lens according to the light and place the lens in the center of the support base 102 for easy measurement.

[0038] Furthermore, the top of the support seat 102 is fixedly connected to the support tube 104 and the airbag 105, the laser pen 213 is located directly above the support tube 104, and the inside of the support seat 102 is fixedly connected to the trachea 106. Both ends of the trachea 106 pass through the support seat 102, and one end of the trachea 106 is fixedly connected to the needle tube 107.

[0039] The laser pen 213 is located on the central axis of the support tube 104, and the height of the airbag 105 is higher than the support tube 104. When the lens is placed on the airbag 105, the airbag 105 is squeezed and uses the support tube 104 to support the lens. The support tube 104 and the airbag 105 can support the hyperbolic lens. The support tube 104 supports the middle part of the lens, and the airbag 105 supports the edge of the lens to ensure that the hyperbolic lens can be measured. When the lens is placed on the airbag 105, the lens is pressed down to make it fit tightly with the airbag 105. Then, a part of the air near the support tube 104 is extracted through the needle tube 107 and the air tube 106, so that the air inside the airbag 105 is reduced to create a weak vacuum environment, so that the lens can be adsorbed on the airbag 105, so that the lens will not slip off the support tube 104 during the measurement process.

[0040] During use, when the laser lens is placed on the airbag 105, the lens is illuminated by the laser pen 213, so that the worker can adjust the position of the lens according to the light and place the lens in the center of the support seat 102. After calibration, the lens is pressed down to make it fit tightly with the airbag 105. Then, a part of the air near the support tube 104 is extracted through the needle tube 107 and the air tube 106, so that the lens is adsorbed on the airbag 105. Then, the connecting plate 203 is lifted, and the rectangular box 201 is moved toward the support seat 102 by the electric telescopic rod 211, so that the roller 208 is located directly above the lens. Then, the connecting plate 203 is released so that the roller 208 and the lens are in contact with each other.

[0041] At this time, the two pressure sensors 204 are turned on, and then the electric telescopic rod 211 is used to drive the rectangular box 201 to move at a constant speed, so that the roller 208 rolls along the curved surface of the lens. The roller 208 will not directly rub against the mirror surface, thereby avoiding scratching the lens. The roller 208 will drive the connecting plate 203 up and down due to the curved surface, so that the connecting plate 203 will squeeze the two springs 205, so that the two springs 205 squeeze the two pressure sensors 204 under the interaction force. The two pressure sensors 204 will provide accurate pressure data to the curvilinear meter 103, so that the curvature of the lens surface can be calculated and measured by the curvilinear meter 103.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
