Description

[Technical field] The present application belongs to the technical field of optical lens processing equipment, and specifically relates to a fully automatic lens centering device and centering method. [Background technology] A lens centering and edge grinding machine is a mechanical device used for lens processing. Through the lens centering and edge grinding machine, the edges of the lenses can be trimmed and processed so that the size, shape and surface quality of the lenses meet the requirements for fitting. The lenses need to be centered before edge grinding. For lenses with smaller curvatures, traditional edge grinding machines absorb the lenses through suction components and then rotate them at high speed to automatically adjust the lenses to the center position. However, lenses with larger curvatures will be significantly affected by centrifugal force when rotating at high speeds, resulting in the inability to stably center them. The centrifugal force will cause the lenses to shift outward along the edge of the curve and cannot remain at the center of rotation. Therefore, lenses with larger curvatures need to be centered manually through manual calibration. However, this method relies on the skills and experience of the operator, which can easily lead to unstable centering accuracy, low efficiency, high labor intensity, and prone to errors. [Summary of the invention] In order to solve the problem of unstable centering accuracy and low efficiency caused by manual centering of lenses with larger curvatures in the prior art, the present application provides a fully automatic lens centering device and centering method.

[Specific implementation method] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying 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.

[0018] See also Figures 1 to 8 A fully automatic lens centering device comprises a frame 1, a mounting base 2 arranged on the frame 1, a suction component 3 arranged on the mounting base 2 and used for adsorbing and driving the lens to be processed to rotate, a cross-line emitting lens 4 arranged on the frame 1 and located on one side of the suction component 3, an imaging receiving lens 5 arranged on the frame 1 and coaxially arranged with the cross-line emitting lens 4 and the suction component 3, a computer 9 electrically connected to the imaging receiving lens 5 and the suction component 3 and deriving the center of a circle according to the rotation path of an imaging cross 6 and generating the coordinates of a reference cross 7, and driving the suction component 3 to drive the lens to be processed to rotate to a position to be adjusted 8 and generate the coordinates of the imaging cross 6, and a correction mechanism 10 electrically connected to the computer 9 and performing position correction on the lens to be processed, wherein the imaging cross 6 emitted by the cross-line emitting lens 4 passes through the suction component 3 and the lens to be processed in turn and is received by the imaging receiving lens 5.

[0019] In this embodiment, the imaging cross position of the lens during rotation is monitored in real time through the cooperation of the cross-line transmitting lens and the imaging receiving lens. The computer connects the highest point, lowest point, leftmost point, and rightmost point of the imaging cross rotation path into a straight line, and then connects the leftmost and rightmost points into a straight line. The intersection is taken as the center of the circle and a reference cross coordinate is generated. Subsequently, the computer drives the suction component to adjust the lens to the position to be adjusted, and further generates the imaging cross coordinate. By comparing with the reference cross coordinate, the computer can accurately calculate the offset of the lens and guide the correction mechanism to perform the corresponding position correction. It eliminates the dependence on the operator's skills and experience, ensures the stability of the centering accuracy, and improves production efficiency. In addition, since this process does not require human intervention, the occurrence of human errors is reduced; The computer calculates the angle α between the positive Y axis of the reference cross and the current origin coordinates of the imaging cross and the straight line formed by the origin coordinates of the reference cross, and drives the suction assembly to drive the lens to be processed to rotate until the angle α is 0°, and then stops rotating to reach the position to be adjusted, and approaches the position to be adjusted. If the angle α is less than 5°, the rotation speed is slowed down to ensure accuracy; The computer calculates the offset along the Y axis according to the origin coordinates of the imaging cross at the position to be adjusted and the origin coordinates of the reference cross, drives the correction mechanism to move and pushes the lens to be processed until the imaging cross is aligned with the reference cross to reach the alignment position to complete automatic correction, and approaches the reference position. If the offset along the Y axis is less than 5mm, the moving speed is slowed down to ensure accuracy.

[0020] Further, as a preferred implementation mode of this solution but not limiting, the correction mechanism 10 includes: A horizontal module 101, which is disposed on the frame 1 and can move on the frame 1 in a horizontal direction; A lifting module 102, which is disposed on the horizontal module 101 and can be lifted and lowered on the horizontal module 101 in a vertical direction; The alignment module 103 is disposed on the lifting module 102 and is used to push the lens to be processed downward from the adjustment position 8 to the reference position 11 . The horizontal module 101 cooperates with the lifting module 102 to move the alignment module 103 to the processing station 12 .

[0021] In this embodiment, the alignment module 103 is precisely positioned in three-dimensional space, so that the lens to be processed can be accurately pushed from the to-be-adjusted position 8 to the reference position 11. This design not only improves the accuracy and stability of the centering operation, but also significantly improves production efficiency.

[0022] Furthermore, as a preferred implementation of the present solution but not a limitation, an imaging channel 31 is provided in the suction component 3 and penetrates the suction component 3 along the axial direction.

[0023] In this embodiment, it is ensured that the imaging cross 6 emitted by the cross-line emitting lens 4 can pass through the suction component 3 without hindrance and be accurately projected onto the lens to be processed, and then be clearly received by the imaging receiving lens 5. This structure avoids the imaging error caused by the occlusion of the suction component 3 and improves the centering accuracy.

[0024] Furthermore, as a preferred implementation of the present invention but not a limitation, the alignment module 103 includes a pushing frame 1031 arranged on the driving end of the lifting module 102, and the pushing frame 1031 is provided with a lifting driving member 1032 that can be lifted and lowered in the vertical direction, and the lifting driving member 1032 is provided with an abutment member 1033 on the driving end for pushing the lens to be processed.

[0025] In this embodiment, by providing a push frame 1031 at the driving end of the lifting module 102, and configuring a lifting driving member 1032 that can be lifted and lowered in the vertical direction on the pushing frame 1031, accurate pushing and positioning of the lens to be processed is achieved. This design ensures that the lens can obtain a stable and controllable displacement when it is pushed to the reference position 11, thereby improving the accuracy and reliability of the centering operation. The abutment member 1033 on the driving end of the lifting driving member 1032 directly contacts the lens, and through its vertical movement, accurate adjustment of the lens is achieved, reducing deviations caused by mechanical errors or human operations.

[0026] Further, as a preferred implementation of this solution but not limiting, the horizontal module 101 includes: An X-axis slide rail 1011 is provided on the frame 1 and extends along the X-axis direction; An X-axis slide 1012, which is slidably disposed on the X-axis slide rail 1011; An X-axis driving member 1013, which is disposed on the frame 1 and is used to drive the X-axis slide 1012 to move along the X-axis slide rail 1011; A Y-axis slide rail 1014, which is disposed on the X-axis slide 1012 and extends along a Y-axis direction perpendicular to the X-axis; A Y-axis slide 1015, which is slidably disposed on the Y-axis slide rail 1014 and connected to the lifting module 102; The Y-axis driving member 1016 is disposed on the X-axis slide 1012 and is used to drive the Y-axis slide 1015 to move along the Y-axis slide rail 1014 .

[0027] In this embodiment, the X-axis drive and the Y-axis drive are driven by servo motors, and the dual-axis linkage structure design enables the alignment module 103 to cover a wider range of work and achieve positioning at any position on the horizontal plane, thereby improving the flexibility and accuracy of the centering operation. The independent control of the X-axis and Y-axis drive components enables the module to quickly respond to the computer's instructions and perform efficient position adjustment, meeting the dual requirements of speed and accuracy for automated processing.

[0028] Furthermore, as a preferred embodiment of the present invention but not a limitation, the suction assembly 3 includes a suction shaft 32 arranged on the mounting base 2, an adsorption device 33 arranged at one end of the suction shaft 32, and a first driving device 34 arranged at the other end of the suction shaft 32, and the suction shaft 32 drives the adsorption device 33 to rotate through the first driving device 34.

[0029] In this embodiment, the first driving device uses a servo motor, a stepper motor, etc., to achieve stable adsorption and precise rotation of the lens to be processed. This design ensures that the lens can be firmly fixed during the centering process, avoids deviation or falling due to loose adsorption, and improves the reliability and safety of the centering operation. The first driving device 34 directly drives the adsorption device 33 to rotate by sucking the rotating shaft 32, simplifies the transmission structure, reduces energy loss, and improves the accuracy and efficiency of the rotation movement.

[0030] Further, as a preferred implementation manner of the present solution but not a limitation, the X-coordinate and Y-coordinate of the reference position 11 corresponding to the imaging cross 6 are both zero and coincide with the coordinates of the reference cross 7, and the X-coordinate of the position to be adjusted 8 corresponding to the imaging cross 6 is zero and the Y-axis coordinate is a positive number.

[0031] In this embodiment, it is ensured that the optical center of the lens is precisely aligned with the rotating axis of the edge grinder after the centering operation is completed, thereby ensuring the accuracy and consistency of the processing. The position to be adjusted 8 is set so that the X coordinate of the imaging cross 6 is zero and the Y axis coordinate is a positive number, which facilitates the correction mechanism 10 to adjust the position from top to bottom. The computer 9 can 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 centering.

[0032] Furthermore, as a preferred implementation manner of the present solution but not limiting, it also includes a display screen 13 electrically connected to the computer 9 and used for displaying the relative positions of the imaging cross 6 and the reference cross 7 .

[0033] In this embodiment, the relative positions of the imaging cross 6 and the reference cross 7 are displayed in real time, so that 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 centering accuracy. The display screen 13 can update the position change of the imaging cross 6 in real time, so that the operator can promptly discover and correct the deviation and ensure the accuracy of the centering operation. In addition, the display screen 13 can also display other relevant information, such as the offset, adjustment steps and processing status of the lens, to provide comprehensive decision support for the operator. The function of the display screen 13 can be further expanded, such as integrating a touch operation interface, so that the operator can directly perform operations such as parameter setting, command input and troubleshooting on the screen, thereby improving the efficiency and experience of human-computer interaction. Alternatively, the display screen 13 can be combined with remote control technology to realize remote monitoring and operation of the centering equipment, which is convenient for equipment maintenance and technical support at the production site.

[0034] A fully automatic lens centering method comprises the following steps: S1, after the lens to be processed is in place at the suction assembly 3, the suction assembly 3 starts to rotate; S2, the imaging receiving lens 5 receives the imaging cross 6 after the cross line transmitting lens 4 passes through the lens to be processed; S3, the computer 9 obtains the center of the circle according to the rotation path of the imaging cross 6 and generates the coordinates of the reference cross 7; S4: the computer 9 drives the suction assembly 3 to drive the lens to be processed to rotate to the position to be adjusted 8 and generates the coordinates of the imaging cross 6; S5, the computer 9 drives the correction mechanism 10 to push the lens to be processed from the position to be adjusted 8 to the reference position 11; S6, the correction mechanism 10 is reset.

[0035] In this embodiment, efficient and accurate centering of the lens is achieved. In S1, the lens to be processed is firmly fixed by the suction component 3 and starts to rotate, preparing for subsequent imaging and calculation. In S2, the imaging receiving lens 5 receives and analyzes the imaging cross 6 after the cross-line transmitting lens 4 passes through the lens, and obtains the position information of the lens. In S3, the computer 9 calculates the center of the lens according to the rotation path of the imaging cross 6, generates the coordinates of the reference cross 7, and provides a reference for subsequent adjustments. In S4, the computer 9 controls the suction component 3 to rotate the lens to the position to be adjusted 8, and obtains the coordinates of the imaging cross 6 again to calculate the offset of the lens. In S5, the computer 9 accurately pushes the lens from the position to be adjusted 8 to the reference position 11 according to the offset instruction correction mechanism 10 to complete the centering operation. Finally, in S6, the correction mechanism 10 is reset to prepare for the next operation. The beneficial effect of this method is that it is highly automated and accurate, reduces manual intervention, and improves production efficiency and centering accuracy.

[0036] Further, as a preferred implementation manner of this solution but not limiting, S5 includes: S51, the X-axis driving member 1013 drives the X-axis slide 1012 to move along the X-axis slide rail 1011 to a position corresponding to the X-axis coordinate of the processing station 12; S52, the Y-axis driving member 1016 drives the Y-axis slide 1015 to move along the Y-axis slide rail 1014 to a position corresponding to the Y-axis coordinate of the processing station 12; S53 , the lifting driving member 1032 drives the abutting member 1033 to push the lens to be processed from the to-be-adjusted position 8 to the reference position 11 .

[0037] The working principle of this embodiment is as follows: The present application discloses a fully automatic lens centering device and centering method. Through the cooperation of a cross-line transmitting lens and an imaging receiving lens, the imaging cross position of the lens during rotation is monitored in real time. The computer calculates the center of the lens based on the data and generates a reference cross coordinate. Subsequently, the computer drives the suction component to adjust the lens to the position to be adjusted, and further generates the imaging cross coordinate. By comparing with the reference cross coordinate, the computer can accurately calculate the offset of the lens and guide the correction mechanism to perform the corresponding position correction. The dependence on the operator's skills and experience is eliminated, the stability of the centering accuracy is ensured, and the production efficiency is improved. In addition, since this process does not require human intervention, the occurrence of human errors is reduced.
