[0066] The embodiments of the present application disclose an optical lens ellipticity repair suction cup tool.

[0067] Please refer to Figure 1 An embodiment of the optical lens ellipticity repair suction cup tool provided in the embodiments of the present application includes:

[0068] The tool body 100.

[0069] A plurality of suction holes 41 are arranged on the top of the tool body 100 in a circumferential distribution and are used for adsorbing the step surface of the lens to be repaired 10. Specifically, a circle of suction holes 41 is arranged on the top of the tool body 100 close to the outer edge, which is used for adsorbing the step surface / bottom edge of the lens to be repaired 10 to fix the lens to be repaired 10, avoiding the problem of ellipticity deformation caused by adsorbing the entire lens.

[0070] The tool body 100 is also provided with a ventilation hole 101, which is used for connecting the lens cavity surrounded between the lens to be repaired 10 adsorbed on the tool body 100 and the working body with the outside. The ventilation hole 101 is designed to connect the lens cavity surrounded between the lens to be repaired 10 adsorbed on the tool body 100 and the working body with the outside, avoiding the passive generation of negative pressure in the lens cavity, which causes the ellipticity deformation of the lens.

[0071] The tool designed as above can reduce the deformation of the lens to be repaired 10 to a small range without causing other defects.

[0075] The quick centering base 9 is in a T-shaped structure, which is fixed at the bottom of the suction cup piece and is synchronously rotatably connected with the suction cup piece.

[0076] The quick centering base 9 is provided with a negative pressure passage 91 penetrating through itself, the suction cup member is provided with a negative pressure chamber 104, the bottom of the suction cup member is provided with a negative pressure communication port 71 communicating with the negative pressure chamber 104 and the negative pressure passage 91, and the suction holes 41 are arranged on the top of the suction cup member.

[0077] Further, as shown in Figures 1 to 4 , for the structure design of the suction cup member, the suction cup lower plate 7 and the suction cup upper plate 4 can both be flat plate structures, without limitation.

[0078] The suction cup lower plate 7 is fixed on the quick centering base 9 by the first fastener 5, and sealed by the base sealing ring 8. The base sealing ring 8 serves to improve the connection sealing between the suction cup lower plate 7 and the quick centering base 9, to avoid air leakage at the connection.

[0079] The negative pressure communication port 71 is arranged on the suction cup lower plate 7, and the suction cup upper plate 4 is fixed on the suction cup lower plate 7 by the second fastener 1, and a negative pressure chamber 104 is formed therebetween.

[0080] The suction cup upper plate 4 and the suction cup lower plate 7 are sealed by the suction cup sealing ring 6, which serves to improve the connection sealing between the suction cup upper plate 4 and the suction cup lower plate 7, to prevent compressed air leakage and cutting fluid from entering.

[0081] The suction holes 41 are arranged on the suction cup upper plate 4.

[0082] Further, as shown in Figure 3 and Figure 4 , for the design of the first fastener 5 and the second fastener 1, they can be threaded fasteners such as screws, bolts, etc., without limitation.

[0083] The suction cup lower plate 7 is provided with a first fastening through hole, and the quick centering base 9 is provided with a first threaded hole corresponding to the first fastening through hole and threadedly connected with the first fastener 5 at a position inside the base sealing ring 8.

[0084] The suction cup upper plate 4 is provided with a second fastening through hole, and the suction cup lower plate 7 is provided with a second threaded hole corresponding to the second fastening through hole and threadedly connected with the second fastener 1 at a position inside the suction cup sealing ring 6.

[0085] The number of the first fastener 5 and the second fastener 1 can both be multiple, to improve the connection reliability.

[0086] Further, the third fastener 2 is installed on the suction cup member.

[0087] The air vent hole 101 is arranged on the third fastener 2, one end of which is used to communicate with the lens cavity, and the other end is used to communicate with the outside.

[0088] The vent hole 101 is integrated in the third fastener 2, which can meet the ventilation needs, further improve the connection stability between the upper plate 4 and the lower plate 7 of the suction cup, and effectively avoid the conduction between the vent hole 101 and the negative pressure chamber 104.

[0089] Further, the third fastener 2 is also a threaded fastener, which can be a screw, a bolt, etc. The third fastening through hole is arranged on the upper plate 4 of the suction cup, and the third threaded hole which penetrates itself and is in threaded connection with the third fastener 2 is arranged on the lower plate 7 of the suction cup at a position inside the sealing ring 6 of the suction cup.

[0090] Further, in order to prevent the negative pressure chamber 104 from leaking at the first fastener 5, the first fastening sealing ring 31 is arranged between the upper plate 4 and the lower plate 7 of the suction cup and surrounds the second fastening through hole.

[0091] Similarly, the second fastening sealing ring 32 is arranged between the upper plate 4 and the lower plate 7 of the suction cup and surrounds the third fastening through hole, so as to further improve the sealing performance.

[0092] Further, as shown in Figure 4 and Figure 5 , the negative pressure chamber 104 includes the main cavity 102 and the waterproof cavity 103.

[0093] The waterproof cavity 103 is annularly arranged outside the main cavity 102 and is in communication with the main cavity 102. The waterproof cavity 103 is a stepped cavity arranged from bottom to top along the direction close to the main cavity 102, that is, a “pagoda-shaped airway” structure. The design of the waterproof cavity 103 effectively plays a waterproof role. Even if a small amount of water enters from the adsorption hole 41, it can be temporarily stored at the bottom of the waterproof cavity 103, so as not to be immediately sucked into the machine tool cylinder, causing damage to the machine tool cylinder.

[0094] The adsorption hole 41 is in communication with a position of the waterproof cavity 103 away from the main cavity 102, so as to ensure the waterproof effect of the waterproof cavity 103.

[0095] Further, as shown in Figure 5 , the annular step 42 is arranged at a position outside the plurality of adsorption holes 41 on the top of the tool body 100. The design of the annular step 42 can leave a cutting space for the diameter of the cutting lens 10 to be repaired.

[0096] The application also discloses an optical lens ellipsity repair dialing method, which is characterized by being applied to a repair device, and the repair device includes a machine tool body, an optical lens ellipsity repair suction cup tool, a dialing device, and a repair device.

[0097] The machine tool main body is an existing machine tool device, the optical lens ellipsity repair suction cup tool can be installed on the workpiece shaft of the machine tool main body, and is used for adsorbing and fixing the repaired lens 10, and the machine tool main body can drive the optical lens ellipsity repair suction cup tool to rotate.

[0098] The dialing device is an existing dialing mechanism, which is used for dialing the repaired lens 10 adsorbed on the optical lens ellipsity repair suction cup tool.

[0099] As shown in Figures 6 to 9 , the repair device is a grinding machine, which is used for cutting the repaired lens 10 adsorbed on the optical lens ellipsity repair suction cup tool.

[0100] The method comprises the steps of:

[0101] S1, the optical lens ellipsity repair suction cup tool is installed on the machine tool workpiece shaft of the machine tool main body, and then the repaired lens is adsorbed. Specifically, after the installation of the optical lens ellipsity repair suction cup tool is completed, the adsorption plane of the suction cup upper plate is milled once, so that the adsorption plane is used as a positioning reference, and the positioning error is eliminated, and then the repaired lens is adsorbed.

[0102] S2, install the dialing device, and make the detection head of the dialing device contact with the outer peripheral surface of the repaired lens.

[0103] S3, drive the repaired lens to rotate one circle by the machine tool main body, and obtain two position point groups from the dialing device, wherein one position point group comprises the position points pointed by the pointer in the dial gauge when the repaired lens rotates to 90° and 270°, and the other position point group comprises the position points pointed by the pointer when the repaired lens rotates to 0° and 180°. Specifically, when the repaired lens is adsorbed and fixed on the suction cup upper plate, due to the existence of clamping error, the repaired lens cannot be clamped in the geometric center, that is, the center of the repaired lens does not coincide with the rotation center of the machine tool workpiece shaft.

[0104] S4, judge whether the two position points in each of the two position point groups coincide. Specifically, as shown in Figure 7 , taking the four position points ABCD obtained after the repaired lens rotates one circle as an example, wherein the A position point corresponds to the rotation angle 0°, the C position point corresponds to the rotation angle 180°, that is, the A position point and the C position point constitute a position point group; the B position point corresponds to the rotation angle 90°, and the D position point corresponds to the rotation angle 270°, that is, the B position point and the D position point constitute another position point group. Judge whether the A position point and the C position point coincide, and whether the B position point and the D position point coincide, wherein the coincidence referred to herein can be 0≤the absolute value of the reading difference between the two position points≤a preset error value.

[0105] S5, if yes, remove the dialing device, and then repair the lens to be repaired through the repairing device. Specifically, as shown in FIG. 8, if the two position points of each of the two position point groups coincide, that is, the A position point in one of the position point groups coincides with the A position point, and the B position point in the other position point group coincides with the B position point, it is considered that the lens has been centered. After the centering is completed, the lens to be repaired is cut through the repairing device, so that the lens to be repaired finally has the effect as shown in FIG. 9. Figure 8 ， ， Figure 9

[0106] S6, if no, record the two position points of the position point group in which the position points do not coincide, and then rotate the lens to be repaired to the position point pointed by the pointer through the machine tool body. Specifically, there are two cases of non-coincidence, one is that only one position point group has non-coincidence, and the other is that both of the two position point groups have non-coincidence. When both of the two position point groups have non-coincidence, one of the position point groups is selected for dialing fine adjustment.

[0107] S7, translate the lens to be repaired to the center position between the two position points pointed by the pointer. Specifically, as shown in FIG. 10, for example, the A position point and the C position point are selected for dialing fine adjustment, and then the lens to be repaired is rotated to the A position point or the C position point pointed by the pointer. Taking the A position point as an example, according to the position relationship between the A position point and the C position point, it is determined whether the center of the lens to be repaired is on the left side or the right side of the rotation center of the tooling, as shown in FIG. 11. When the A position point pointed by the pointer is on the left side of the C position point, it is considered that the center of the lens to be repaired is on the left side of the rotation center, and then the lens to be repaired is moved to the right by knocking or pushing the lens to be repaired with the corresponding tool. Taking the C position point as an example, it can be seen that the C position point is on the right side of the A position point, so when the lens to be repaired is adjusted, the lens to be repaired needs to be moved to the left. Similarly, the B position point is on the right side of the D position point, that is, the center of the lens to be repaired in the state of the B position point is on the right side of the rotation center, so the lens to be repaired needs to be moved to the left. The D position point is on the left side of the B position point, so the lens to be repaired needs to be moved to the right. When one translation step is completed and the pointer points to the middle position point between the two position points, it is considered that the translation is completed. Figure 7 Figure 7 After the lens to be repaired is adjusted once through translation, the step S3 is returned to be executed, and the steps S3-S6 are repeated until both of the two position point groups are centered as shown in FIG. 12.

[0108] Figure 8 ​​​​​​The position points obtained again after each step 5-6 of the dialing adjustment are different positions in the shown coincident state. Each dialing adjustment is performed for one of the position point groups, and the process is repeated until both position point groups are in the coincident state. Each position point in the present application is an example, and the actual position points recorded in the actual operation are used as the criterion.

[0109] The dialing method described above can dial the lens with elliptical deformation to the minimum runout, cut off the maximum deformation, and reduce or eliminate the elliptical deformation.

[0110] The optical lens elliptical repair suction cup tool and the dialing method provided in the present application are described in detail above. For those skilled in the art, the specific implementation and application range will be changed according to the idea of the embodiments of the present application. In summary, the content of the specification should not be understood as a limitation of the present application.
