Description

Technical Field

[0001] The invention relates to the technical field of polishing sheet detection, in particular to a device and method for detecting the curvature of an optical polishing sheet. Background Art

[0002] Optical polishing sheets are transparent materials with one or more curved surfaces made of glass optical materials. After polishing, they are often assembled with eyeglass frames to form glasses, which are used to correct the user's vision and obtain a clear field of vision. After the optical polishing sheet is manufactured, the curvature in the optical polishing sheet needs to be measured to check whether the optical polishing sheet meets the use requirements. When the machine measures the optical polishing sheet, it is necessary to change different angles of the optical polishing sheet for measurement. During measurement, the angle adjustment range of the optical polishing sheet is small, which may result in omissions during detection; and the optical polishing sheet usually needs to be cleaned before detection to ensure a clean surface and not affect the detection accuracy. However, the process of cleaning first and then detecting reduces the detection efficiency of the optical polishing sheet. Summary of the invention

[0003] The object of the present invention is to provide a device and method for detecting the curvature of an optical polishing sheet, so as to solve the problems raised in the prior art.

[0005] The staff places the polishing sheet that needs to be inspected on the top of the fixed plate and makes it contact with the suction cup. Then the controller controls the air pump to start. The air pump extracts the air in the space between the suction cup and the polishing sheet, so that the suction cup sucks the polishing sheet and fixes it. Then the controller controls the driving device to start. After the driving device is started, it drives the detection equipment to move. The detection equipment then moves to the side close to the polishing sheet, so that the detection equipment contacts the surface of the polishing sheet. Finally, the controller controls the detection equipment and the No. 1 motor in the fixed table to start. After the No. 1 motor is started, the drive shaft of the No. 1 motor drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the fixed plate to rotate, and then the fixed plate drives the polishing sheet to rotate. When the polishing sheet rotates, the detection equipment moves from the edge of the polishing sheet to the center of the polishing sheet under the action of the driving device, thereby completing the curvature detection of the polishing sheet.

[0009] Preferably, the inner wall of the arc plate is provided with a plurality of water spray outlets, and the plurality of water spray outlets are arranged around the axis of the arc plate, a plurality of water pipes are provided inside the arc plate, and the water pipes correspond to the water spray outlets one by one, a water trough is provided on the top of the arc plate, a water pump is provided inside the water flow pool, and the water pump is connected to the water trough through a pipeline.

[0011] Preferably, a pressurized chamber is provided in the middle of the detection column, a turbofan is provided in the pressurized chamber, an electromagnetic coil is provided in the inner wall of the pressurized chamber, a magnetic conductor is provided on the turbofan, the turbofan is rotatably connected to the pressurized chamber, a plurality of air inlets are provided on the top of the pressurized chamber, a plurality of air outlets are provided on the side of the detection column close to the detection slot, and a delivery pipe is provided between the air outlet and the pressurized chamber.

[0012] Preferably, the water spray port is arranged obliquely toward the side close to the detection column, the air outlet is arranged obliquely toward the side close to the cleaning ring, the bottom of the side of the cleaning ring is provided with fluff, the cleaning ring is made of rubber, the detection roller is made of resin, and the distance between the bottom plane of the cleaning ring and the top plane of the detection column is greater than the distance between the bottom end of the detection roller and the top plane of the detection column; After the polishing sheet is fixed by the suction cup, the controller controls the No. 2 motor and the No. 3 motor to start, and the driving shaft of the No. 2 motor drives the friction wheel to rotate. When the friction wheel rotates, it contacts the vertical groove, and then the friction wheel drives the vertical plate to move toward the side close to the water pool. When the vertical plate moves, it drives the horizontal plate to move, so that the horizontal plate moves toward the side close to the polishing sheet. At the same time, the driving shaft of the No. 3 motor drives the transmission wheel to rotate. When the transmission wheel rotates, it contacts the horizontal groove, and then the transmission wheel drives the horizontal plate to move. The horizontal plate moves along the horizontal groove and moves toward the edge of the polishing sheet. When the horizontal plate moves, it drives the detection column to move. In the process of the horizontal plate moving from the center of the polishing sheet to the edge of the polishing sheet, since the distance between the bottom plane of the cleaning ring and the top plane of the detection column is greater than the distance between the bottom end of the detection roller and the top plane of the detection column, the cleaning ring first contacts the surface of the polishing sheet, and the detection roller does not contact the surface of the polishing sheet at this time. At the same time, the controller controls the water pump in the water flow pool to start, and the water pump extracts water from the water flow pool, and then transports water to the water delivery trough through the pipeline. The water moves from the water delivery trough to the water delivery pipe, and finally is transported to the water spray port through the water delivery pipe, and is sprayed from the water spray port to the surface of the polishing sheet, and the sprayed water washes the impurities on the surface of the polishing sheet; When the detection column moves to the edge of the polishing sheet driven by the horizontal plate, the controller controls the second motor to start, so that the second motor drives the horizontal plate to descend, thereby causing the detection roller to descend and contact the surface of the polishing sheet; When the detection roller contacts the surface of the polishing sheet, the detection roller is squeezed by the polishing sheet, so that the detection roller moves to the side close to the detection groove, and then the detection roller pushes the moving frame to move. When the moving frame moves, it squeezes the pressure-sensitive spring. After being squeezed, the pressure-sensitive spring pushes the pressure plate to move, so that the pressure plate moves to the side away from the detection roller. The pressure plate then applies pressure to the pressure sensor, and the pressure sensor then converts the pressure signal into an electrical signal and transmits it to the controller. The controller calculates the distance between the contact position between the detection roller and the polishing sheet and the top plane of the detection column according to the electrical signal (the smaller the pressure, the greater the distance, and the greater the pressure, the shorter the distance); Then the controller controls the No. 1 motor to start, and the driving shaft of the No. 1 motor drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the fixed plate to rotate, and then the fixed plate drives the polishing sheet to rotate. While the polishing sheet rotates, the No. 3 motor drives the horizontal plate to move along the horizontal groove, so that the horizontal plate drives the detection column to move. At this time, the detection column moves from the edge of the polishing sheet to the center of the polishing sheet. As the polishing sheet rotates, the detection roller moves horizontally, so that the movement trajectory of the detection roller on the surface of the polishing sheet becomes a spiral state. The detection roller moves on the surface of the polishing sheet, and then the distance between the contact position of the detection roller and the polishing sheet and the top plane of the detection column is monitored in real time, thereby forming height change information presented in a spiral form. The controller takes the center of the spiral as the base point, and shoots extension lines from the center of the spiral to the surrounding areas of the spiral. The height information detected by the positioning point between two adjacent spiral lines can be used to obtain the curvature of the polishing sheet, thereby realizing the curvature detection of the polishing sheet. When the detection roller contacts the surface of the polishing sheet, the detection column drives the cleaning ring to descend. Since the cleaning ring is made of rubber, it is squeezed and deformed, so that the cleaning ring contacts the surface of the polishing sheet as much as possible. Then, when the detection roller detects the polishing sheet, the controller controls the electromagnetic coil in the pressurization chamber to be energized. After the electromagnetic coil is energized, a magnetic force is generated. The magnetic force attracts the magnetic conductor in the turbofan. Then, the turbofan generates a rotational force under the action of the electromagnetic coil, and then the outside air is transported to the pressurization chamber through the air inlet, and then transported to the delivery pipe after being pressurized by the turbofan, and then transported to the air outlet through the delivery pipe, and finally sprayed to the polishing sheet through the air outlet; At the same time as the extruded air is sprayed out, the water nozzle also sprays water toward the polishing sheet. Since the water nozzle is arranged inclined toward the side close to the detection column and the air outlet is arranged inclined toward the side close to the cleaning ring, the water is disturbed by the pressurized air after contacting the surface of the polishing sheet, and then moves toward the edge of the cleaning ring under the action of the pressurized air, thereby keeping the peripheral area of ​​the detection roller dry and avoiding the influence of water on the detection accuracy of the detection roller. The water moves toward the edge of the cleaning ring and cooperates with the fluff at the bottom of the cleaning ring to wipe and clean the surface of the polishing sheet, and cleans the impurities on the surface of the polishing sheet, thereby achieving the effect of simultaneous cleaning and detection, saving processes and improving the efficiency of polishing sheet detection.

[0013] A detection method for a curvature detection device for an optical polishing sheet, the detection method comprising the following specific steps: S1. Place the polishing sheet on a fixed plate and fix it with a suction cup; S2, the driving device drives the detection device to move toward the side close to the polishing sheet; S3, the testing equipment performs curvature testing on the surface of the polishing sheet; S4. During the curvature detection process, the surface of the polishing sheet is cleaned by a cleaning ring, water and pressurized air, and the area around the detection roller is dried; S5. After the inspection is completed, remove the polishing sheet.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The detection column moves from the edge of the polishing sheet to the center of the polishing sheet and cooperates with the rotation of the polishing sheet to make the movement trajectory of the detection roller on the surface of the polishing sheet in a spiral state. The detection roller moves on the surface of the polishing sheet, and then monitors the distance between the contact position of the detection roller and the polishing sheet and the top plane of the detection column in real time, thereby forming height change information presented in a spiral form. The controller takes the center of the spiral as the base point, and shoots an extension line from the center of the spiral to the surroundings of the spiral. The height information monitored by the positioning point between two adjacent spiral lines can be used to obtain the curvature of the polishing sheet, thereby realizing the curvature detection of the polishing sheet, thereby solving the problem of changing the different angles of the optical polishing sheet for measurement when measuring the optical polishing sheet. During measurement, the angle adjustment range of the optical polishing sheet is small, which may cause omissions during detection, thereby improving the accuracy of the curvature detection of the polishing sheet.

[0015] 2. While the extruded air is being sprayed out, the water outlet also sprays water toward the polishing sheet. Since the water outlet is tilted toward the side close to the detection column and the air outlet is tilted toward the side close to the cleaning ring, the water is disturbed by the pressurized air after contacting the surface of the polishing sheet, and then moves toward the edge of the cleaning ring under the action of the pressurized air, thereby keeping the peripheral area of ​​the detection roller dry and avoiding the water from affecting the detection accuracy of the detection roller. The water moves toward the edge of the cleaning ring and cooperates with the fluff at the bottom of the cleaning ring to wipe and clean the surface of the polishing sheet, and clean the impurities on the surface of the polishing sheet, thereby achieving the effect of simultaneous cleaning and detection, saving procedures and improving the efficiency of polishing sheet detection.

[0024] A detection method for a curvature detection device for an optical polishing sheet, the detection method comprising the following specific steps: S1, placing the polishing sheet on the fixing plate 13 and fixing it with the suction cup 14; S2, the driving device 2 drives the detection device 3 to move toward the side close to the polishing sheet; S3, the detection device 3 performs curvature detection on the surface of the polishing sheet; S4, during the curvature detection process, the cleaning ring 33, water and pressurized air clean the surface of the polishing sheet, and dry the area around the detection roller 342; S5. After the inspection is completed, remove the polishing sheet.

[0025] Working principle of the present invention: After the polishing sheet is fixed by the suction cup 14, the controller controls the No. 2 motor and the No. 3 motor to start, and the driving shaft of the No. 2 motor drives the friction wheel to rotate. When the friction wheel rotates, it contacts the vertical groove 21, and then the friction wheel drives the vertical plate 22 to move toward the side close to the water pool 11. When the vertical plate 22 moves, it drives the horizontal plate 24 to move, so that the horizontal plate 24 moves toward the side close to the polishing sheet. At the same time, the driving shaft of the No. 3 motor drives the transmission wheel to rotate. When the transmission wheel rotates, it contacts the horizontal groove 23, and then the transmission wheel drives the horizontal plate 24 to move. The horizontal plate 24 moves along the horizontal groove 23, and the horizontal plate 24 moves toward the edge of the polishing sheet. When the horizontal plate 24 moves, it drives the detection column 31 to move; In the process of the horizontal plate 24 moving from the center of the polishing sheet to the edge of the polishing sheet, since the distance between the bottom plane of the cleaning ring 33 and the top plane of the detection column 31 is greater than the distance between the bottom end of the detection roller 342 and the top plane of the detection column 31, the cleaning ring 33 first contacts the surface of the polishing sheet, and the detection roller 342 does not contact the surface of the polishing sheet at this time. At the same time, the controller controls the water pump in the water flow pool 11 to start, and the water pump extracts water from the water flow pool 11, and then transports water to the water delivery trough 323 through the pipeline. The water moves from the water delivery trough 323 to the water delivery pipe 322, and finally transports the water to the water spray port 321 through the water delivery pipe 322, and is sprayed from the water spray port 321 to the surface of the polishing sheet, and the sprayed water washes the impurities on the surface of the polishing sheet; When the detection column 31 moves to the edge of the polishing sheet driven by the horizontal plate 24, the controller controls the second motor to start, so that the second motor drives the horizontal plate 24 to descend, thereby causing the detection roller 342 to descend and contact the surface of the polishing sheet; When the detection roller 342 contacts the surface of the polishing sheet, the detection roller 342 is squeezed by the polishing sheet, so that the detection roller 342 moves to the side close to the detection groove 34, and then the detection roller 342 pushes the moving frame 341 to move. When the moving frame 341 moves, it squeezes the pressure-sensitive spring. After being squeezed, the pressure-sensitive spring pushes the pressure plate to move, so that the pressure plate moves to the side away from the detection roller 342. The pressure plate then applies pressure to the pressure sensor, and the pressure sensor then converts the pressure signal into an electrical signal and transmits it to the controller. The controller calculates the distance between the contact position between the detection roller 342 and the polishing sheet and the top plane of the detection column 31 according to the electrical signal (the smaller the pressure, the greater the distance, and the greater the pressure, the shorter the distance); Then the controller controls motor No. 1 to start, and the driving shaft of motor No. 1 drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the fixed plate 13 to rotate, and then the fixed plate 13 drives the polishing sheet to rotate. While the polishing sheet rotates, motor No. 3 drives the horizontal plate 24 to move along the horizontal groove 23, so that the horizontal plate 24 drives the detection column 31 to move. At this time, the detection column 31 moves from the edge of the polishing sheet to the center of the polishing sheet. As the polishing sheet rotates, the detection roller 342 moves horizontally, so that the movement trajectory of the detection roller 342 on the surface of the polishing sheet is in a spiral state. The detection roller 342 moves on the surface of the polishing sheet, and then the contact position between the detection roller 342 and the polishing sheet and the distance between the top plane of the detection column 31 are monitored in real time, thereby forming height change information presented in a spiral form. The controller takes the center of the spiral as the base point, and shoots an extension line from the center of the spiral to the surrounding areas of the spiral, passing through the positioning point between two adjacent spiral lines (i.e. Figure 7 and Figure 8 The height information monitored by A and B in the figure (A and B are the intersection points of the spiral line and the extended line) can be used to obtain the curvature of the polishing sheet, thereby realizing the curvature detection of the polishing sheet; When the detection roller 342 contacts the surface of the polishing sheet, the detection column 31 drives the cleaning ring 33 to descend. Since the cleaning ring 33 is made of rubber, the cleaning ring 33 is squeezed and deformed, so that the cleaning ring 33 contacts the surface of the polishing sheet as much as possible. Then, when the detection roller 342 detects the polishing sheet, the controller controls the electromagnetic coil in the pressurizing chamber 35 to be energized. After the electromagnetic coil is energized, a magnetic force is generated, and the magnetic conductor in the turbofan 36 is attracted. Then, the turbofan 36 generates a rotational force under the action of the electromagnetic coil, and then the outside air is transported to the pressurizing chamber 35 through the air inlet 351, and then transported to the delivery pipe 353 after being pressurized by the turbofan 36, and then transported to the air outlet 352 through the delivery pipe 353, and finally sprayed toward the polishing sheet through the air outlet 352; At the same time as the squeezed air is sprayed out, the water nozzle 321 also sprays water toward the polishing sheet. Since the water nozzle 321 is arranged inclined toward the side close to the detection column 31, and the air outlet 352 is arranged inclined toward the side close to the cleaning ring 33, the water is disturbed by the pressurized air after contacting the surface of the polishing sheet, and then moves toward the edge of the cleaning ring 33 under the action of the pressurized air, thereby keeping the area around the detection roller 342 dry and avoiding water from affecting the detection accuracy of the detection roller 342. The water moves toward the edge of the cleaning ring 33 and cooperates with the fluff at the bottom of the cleaning ring 33 to wipe and clean the surface of the polishing sheet, and clean the impurities on the surface of the polishing sheet, thereby achieving the effect of simultaneous cleaning and detection.

[0026] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
