Description

[0002] The lens centering and edging machine is a mechanical equipment for processing spectacle lenses. Through the lens centering and edging machine, the edges of the spectacle lenses can be trimmed and processed, so that the size, shape and surface quality of the spectacle lenses meet the requirements of lens fitting. Before edging, the lens needs to be centered. For lenses with small curvature, the traditional edging machine can automatically adjust the lens to the center position by rotating at high speed after the lens is adsorbed by the suction assembly. However, for lenses with large curvature, the lens cannot be stably centered due to the significant centrifugal force when rotating at high speed. The centrifugal force will cause the lens to deviate outward along the curved edge, and the lens cannot be kept at the center of rotation. Therefore, the lenses with large curvature need to be centered manually by manual calibration. However, this method depends on the skills and experience of the operator, and is prone to unstable centering accuracy, low efficiency, high labor intensity and errors. SUMMARY

DETAILED DESCRIPTION

[0044] In order to make the technical problems and beneficial effects of the technical solutions solved by the present application more clear, the present application will be further described in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0045] Please refer to Figures 1 to 8The application discloses a full-automatic lens centering device, which comprises a rack 1, a mounting base 2 arranged on the rack 1, a suction assembly 3 arranged on the mounting base 2 and used for sucking and rotating a lens to be processed, a cross line emitting lens 4 arranged on the rack 1 and located on one side of the suction assembly 3, an imaging receiving lens 5 arranged on the rack 1 and coaxially arranged with the cross line emitting lens 4 and the suction assembly 3, a computer 9 electrically connected with the imaging receiving lens 5 and the suction assembly 3 and used for obtaining a center of a circle and generating a reference cross 7 coordinate according to a rotating path of an imaging cross 6, and a correction mechanism 10 electrically connected with the computer 9 and used for correcting a position of the lens to be processed; and the imaging cross 6 emitted by the cross line emitting lens 4 is sequentially passed through the suction assembly 3 and the lens to be processed and then received by the imaging receiving lens 5.

[0046] In the embodiment, the imaging cross position of the lens in the rotating process is monitored in real time through cooperation of the cross line emitting lens and the imaging receiving lens; the computer obtains the highest point, the lowest point, the leftmost point and the rightmost point of the rotating path of the imaging cross, then connects the highest point and the lowest point into a straight line and connects the leftmost point and the rightmost point into another straight line, takes an intersection point as a center of a circle, and generates a reference cross coordinate. Then, the computer drives the suction assembly to adjust the lens to a position to be adjusted, and further generates an imaging cross coordinate. Through comparison with the reference cross coordinate, the computer can accurately calculate a deviation of the lens and guide the correction mechanism to perform corresponding position correction. The dependence on the skills and experience of operators is eliminated, the stability of centering precision is ensured, and the production efficiency is improved. In addition, since the process does not need manual intervention, the occurrence of human errors is reduced.

[0047] The computer calculates an included angle alpha between the reference cross positive Y axis according to a straight line connecting the current origin coordinate of the imaging cross and the origin coordinate of the reference cross, drives the suction assembly to rotate the lens to be processed to the position to be adjusted until the included angle alpha is 0°, and then stops rotating to reach the position to be adjusted; when the included angle alpha is less than 5°, the rotating speed is slowed down to ensure the precision.

[0048] The computer calculates a deviation along the Y axis according to the origin coordinate of the imaging cross at the position to be adjusted and the origin coordinate of the reference cross, drives the correction mechanism to move and push the lens to be processed to the position to be adjusted until the imaging cross is aligned with the reference cross to reach a position to be corrected and complete the automatic correction; when the deviation along the Y axis is less than 5mm, the moving speed is slowed down to ensure the precision.

[0049] Further, as a preferred embodiment of the application, the correction mechanism 10 comprises:

[0050] A horizontal module 101 is arranged on the rack 1 and can move on the rack 1 in a horizontal direction;

[0054] Further, as a preferred embodiment of the present scheme but not limited, the suction assembly 3 is provided with an imaging channel 31 penetrating through the suction assembly 3 in the axial direction.

[0055] In this embodiment, the imaging cross 6 emitted by the cross line emitting lens 4 can pass through the suction assembly 3 without obstruction and be accurately projected onto the lens to be processed, and then be clearly received by the imaging receiving lens 5. This structure avoids imaging errors caused by the blocking of the suction assembly 3, and improves the centering accuracy.

This design ensures that the lens can obtain stable and controllable displacement when being pushed to the reference position 11, thereby improving the accuracy and reliability of the centering operation.

[0067] In this embodiment, the first driving device adopts a servo motor, a stepping motor, etc., to realize stable suction and accurate rotation of the lens to be processed. This design ensures that the lens can be firmly fixed during centering, avoids deviation or falling due to unstable suction, and improves the reliability and safety of the centering operation. The first driving device 34 directly drives the suction device 33 to rotate through the suction shaft 32, simplifying the transmission structure, reducing energy loss, and improving the accuracy and efficiency of the rotating motion.

The position to be adjusted 8 is set to the X coordinate of the imaging cross 6 being zero and the Y axis coordinate being positive, facilitating the position adjustment of the correction mechanism 10 from top to bottom. This enables the computer 9 to accurately calculate the offset of the lens and guide the correction mechanism 10 to perform accurate adjustment operations, thereby improving the efficiency and accuracy of the centering.

[0070] Further, as a preferred embodiment of the present solution but not limited, it further includes a display screen 13 electrically connected to the computer 9 and displaying the relative positions of the imaging cross 6 and the reference cross 7.

[0071] In this embodiment, the relative positions of the imaging cross 6 and the reference cross 7 are displayed in real time, and the operator can intuitively observe the centering process and results of the lens. This visual design not only improves the convenience of operation, but also enhances the confidence in the accuracy of centering. The display screen 13 can update the position changes of the imaging cross 6 in real time, enabling the operator to timely discover and correct deviations, thereby ensuring the accuracy of the centering operation. In addition, the display screen 13 can also display other related information, such as the offset of the lens, the adjustment steps and the processing status, etc., providing comprehensive decision support for the operator. The function of the display screen 13 can be further expanded, such as integrating a touch operation interface, enabling the operator to directly set parameters, input commands and troubleshoot on the screen, thereby improving the efficiency and experience of human-computer interaction.
