This device determines the MTF value of a lens by measuring its modulation ability for different frequency patterns, thereby judging the resolution and contrast performance of the lens. MTF sorting devices usually include high-resolution sensors, precisely controlled light sources, and complex software algorithms to ensure the accuracy and repeatability of test results. These devices can automatically and quickly screen lenses, sorting them into different quality levels to meet the stringent requirements of imaging performance in different application fields. MTF sorting devices are widely used in lens production, quality control, and research and development fields, and are key tools for improving lens manufacturing precision and ensuring product consistency.

DETAILED DESCRIPTION

[0038] Two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] First embodiment:

[0040] Figures 1-10 As shown, an MTF lens automatic sorting device includes an MTF tester 1, and the input end and the output end of the MTF tester 1 are respectively connected with a material feeding structure and a sorting structure. The material feeding structure is provided with a material feeding mechanism 3 and at least one material bin 4. The material feeding mechanism 3 is used to move the lens to be detected on the tray placing mechanism 5 of the material bin 4 in the material feeding structure to the input end of the MTF tester 1.

[0041] The sorting structure includes a material taking and placing mechanism 2 and at least three material bins 4. The material taking and placing mechanism 2 is used to move the lens detected by the MTF tester 1 to the tray placing mechanism 5 of the designated material bin 4.

[0042] The bottom end of the material feeding mechanism 3 and the material taking and placing mechanism 2 is respectively provided with a movable clamp 6 matched with the MTF tester 1. After the material taking and placing mechanism 2 moves the lens to be detected to the feeding position of the MTF tester 1, the movable clamp 6 at the lower end clamps the lens and sends it to the detection position of the MTF tester 1.

[0043] After the detection is completed, the movable clamp 6 at the lower end of the material feeding mechanism 3 takes out the lens in the MTF tester 1 and resets it to the discharging position. Then the material taking and placing mechanism 2 clamps the lens on the movable clamp 6 and moves to the designated position according to the detection result or the scanning result.

[0044] The two movable clamps 6 are respectively used for the input of the lens to be detected by the MTF tester 1 and the output of the lens after detection.

[0045] The material taking and placing mechanism 2 includes a linear guide rail 21. The movable end of the linear guide rail 21 is connected with a lifting cylinder 22. The movable end of the lifting cylinder 22 is connected with a material taking clamp jaw 23. The material taking clamp jaw 23 moves horizontally and vertically through the linear guide rail 21 and the lifting cylinder 22. After the detection of the lens by the MTF tester 1 is completed, the movable clamp 6 takes out the detected lens and resets it to the designated position. Then the material taking clamp jaw 23 takes away the detected lens and moves to the designated position according to the detection.

[0046] The feeding mechanism 3 comprises a longitudinal guide rail 31 installed on the movable end of a horizontal guide rail, which is an X-axis linear guide rail, and the longitudinal guide rail 31 is a Z-axis linear guide rail;

[0047] A rotary motor is installed on the movable end of the longitudinal guide rail 31, and the rotary motor is installed in a power box on the movable end of the longitudinal guide rail 31. A suction nozzle 32 is drivingly connected to the power output end of the rotary motor, and the suction nozzle 32 penetrates through the power box and is rotationally connected thereto. A driven gear is connected to the suction nozzle 32 on the part of the suction nozzle 32 in the power box. The power output end of the rotary motor is connected to a driving gear meshing with the driven gear. The suction nozzle 32 is driven to rotate by the rotary motor.

[0048] A gas pump matched with the suction nozzle 32 is installed on the movable end of the longitudinal guide rail 31 or on the longitudinal guide rail 31 by a person skilled in the art. The output end of the gas pump is rotationally and sealingly connected to the input end of the suction nozzle 32.

[0049] The side end of the rotary motor is connected to a correction clamp 33 for correcting the position of the lens through an electric telescopic device 35. The electric telescopic device 35 is installed by a person skilled in the art according to the technical requirements, for example, an electric telescopic rod.

[0050] The correction clamp 33 comprises a clamping jaw cylinder connected to the movable end of the electric telescopic device 35. A pair of L-shaped clamping arms are connected to the movable end of the clamping jaw cylinder. After the suction nozzle 32 takes the material, if any laser sensor is blocked, the correction clamp 33 is used for clamping correction. The correction clamp 33 clamps the lens to the standard position.

[0051] A detection ring 34 is detachably connected to the outer end of the suction nozzle 32. At least three sensors for detecting the deviation of the lens are installed on the detection ring 34. The sensors are circumferentially distributed on the detection ring 34 and are used to detect the center deviation of the lens when the lens is initially adsorbed by the suction nozzle 32.

[0052] The sensors comprise laser sensors and pressure sensors. A pair of clamping columns are connected to the top end of the detection ring 34. A clamping groove matched with the clamping columns is formed in the bottom end of the movable end of the longitudinal guide rail 31. A plug and a socket matched with each other are respectively installed on the clamping groove and the clamping columns. When the sensor is a pressure sensor, the detection end of the sensor needs to extend to the same plane of the suction end of the suction nozzle 32, so that when the lens is adsorbed, the overlapping area of the lens and the detection end of the pressure sensor will pressurize the pressure sensor.

[0053] The stock bin 4 comprises a storage box 42 installed on the movable end of a lifting device 41. A plurality of trays 43 are placed in the storage box 42. A tray placing mechanism 5 for taking and placing the trays 43 is arranged at each stock bin 4. A placing rack is clamped to the lower end of each tray 43. A plurality of pairs of slide rails matched with the placing rack are uniformly distributed and installed in the storage box 42. Pressure sensors for detecting whether the placing rack is placed accurately are installed on the top end of the slide rails. The trays 43 are conveniently confirmed to be reset.

[0054] The swing plate mechanism 5 comprises a high support 51 provided with an electric guide rail, and a movable supporting plate 52 for placing the tray 43 is connected to the movable end of the high support 51; an auxiliary supporting table 53 is fixedly connected to the middle part of the high support 51, and two pairs of supporting columns are installed on the auxiliary supporting table 53, and the top ends of the supporting columns are rotatably connected with rollers matched with the movable supporting plate 52.

[0055] The scanning device 7 is installed on one end of the MTF testing machine 1, and is used for scanning the MTF lens to be detected and identifying the information of the MTF lens, so as to classify and place the MTF lens after detection and record the detection result.

[0056] In the working process of the present scheme, the lens is taken out by the feeding mechanism 3, and the lens is first attracted by the suction nozzle 32, and then the detection ring 34 is used to detect whether the lens is deviated, if the lens is deviated, the correction clamp 33 is used for correction, if the lens is not deviated, the lens is released by the suction nozzle 32, and then the correction clamp 33 is used for normal clamping; the correction work is carried out synchronously during the movement of the lens;

[0057] The correction process is as follows: after the sensor detects that the lens is deviated, the suction nozzle 32 maintains negative pressure adsorption, and the correction clamp 33 performs position calibration; the clamping jaw cylinder drives a pair of L-shaped clamping arms to rotate by the same angle, so that the lens is clamped and the center of the lens is located on the central axis of the suction nozzle 32, so that the center correction is realized by clamping; after the lens is clamped stably by the pair of L-shaped clamping arms, the clamping jaw cylinder is driven as a whole by the control electric telescopic device 35 to adjust the position of the lens, until the detection ends of the plurality of sensors are not in contact with the lens, at this time, the position correction of the lens is completed, and the correction process is as shown in Figure 7 ;

[0058] After the lens moves to the scanning device 7, the deviated lens is corrected, the suction nozzle 32 attracts the lens, the correction clamp 33 releases the lens, and then the suction nozzle 32 is driven to rotate by the rotating motor, so that the lens is rotated and scanned by the scanning device 7 to identify the information of the lens; after the scanning is successful, the lens is clamped, then the feeding mechanism 3 moves the lens to the feeding position, then the lens is clamped by the movable clamp 6 below the feeding mechanism 3, finally the lens is input into the MTF testing machine 1 through the movable clamp 6 for testing, and after the lens is tested, the lens is taken out by the movable clamp 6 at the lower end of the taking and feeding mechanism 2;

[0059] If the scanning fails, a signal is sent to the MTF testing machine 1 and the taking and feeding mechanism 2, the MTF testing machine 1 does not detect the lens, and then the movable clamp 6 takes out the lens after the lens is input into the MTF testing machine 1;

[0060] When the lens is taken out from the MTF testing machine 1, the movable clamp 6 at the lower end of the taking and feeding mechanism 2 is reset to the initial position after the lens is taken out from the MTF testing machine 1;

[0061] Then the taking and placing mechanism 2 works, the taking mechanism clamps the lens, and then the lens is transferred to the corresponding tray 43 position;

[0062] The sorting structure is provided with at least three hoppers 4, and one tray is placed on the outer side of each of the three hoppers 4 through the tray changing mechanism 5. The trays 43 at the three hoppers 4 are respectively used to place the lenses that pass the detection, the lenses that do not pass the detection, and the lenses that do not pass the scanning;

[0063] When the tray 43 on the tray changing mechanism 5 is replaced, first, the lifting device 41 is controlled to work, so that the storage box 42 vertically displaces until the tray 43 matches the position of the corresponding slide rail, then the movable supporting plate 52 is driven to displace through the electric guide rail, so that the tray 43 is inserted into the storage box 42, then the storage box 42 is driven to rise by the lifting device 41, so that the slide rail supports the tray 43, and then the movable supporting plate 52 is reset; the storage box 42 is driven to displace again by the lifting device 41, so that another empty tray 43 in the storage box 42 moves to the upper side of the movable supporting plate 52, then the movable supporting plate 52 is driven to insert into the storage box 42; the storage box 42 continues to displace downward by a set distance, so that the movable supporting plate 52 supports the empty tray 43, and then the movable supporting plate 52 is reset to the unloading position outside the storage box 42;

[0064] The automatic sorting of the lenses, from the lens feeding, detection, code scanning and identification, classification and placement to the automatic replacement of the tray, the whole process does not need manual participation, and the working efficiency and accuracy are easily improved. Meanwhile, through the detection ring 34 and the laser sensor, the lens offset can be detected and corrected in real time, the position accuracy of the lens before detection is ensured, and the detection precision is improved. Moreover, the present scheme does not make major changes to the core structure of the existing equipment, has low cost, and has strong adaptability.

[0065] The second embodiment:

[0066] Figure 11 It is shown that the auxiliary sorting system further includes a processor, and the processor is connected with a control module, a data processing module, a data acquisition module and a data storage module;

[0067] The control module is used to control the corresponding associated equipment according to the received instructions, including but not limited to controlling the start, stop and running speed of the MTF tester 1, the feeding mechanism 3, the taking and placing mechanism 2, the tray changing mechanism 5 and other components, so as to ensure that each component works in order according to the preset program;

[0068] The data processing module is used to receive and process the detection results transmitted by the MTF tester 1 and the scanning device 7, divide the lenses into three categories of passing the detection, not passing the detection and not passing the scanning according to the detection results, and generate corresponding placement instructions; the control module controls the related equipment to transfer the lenses in the MTF tester 1 to the tray 43 at the specified position according to the placement instructions.

[0069] The data acquisition module is configured to acquire monitoring data, including scanning information, position offset detection information, and lens placement count information in the tray, and transmit the acquired monitoring data to the data processing module.

[0070] The data storage module is configured to store the monitoring data and system operation log data.

[0071] The data storage module is provided with a counting unit, which is configured to record the number of times of lens placement of the taking and placing mechanism 2 at each tray arranging mechanism 5. When the number of times of lens placement at any tray arranging mechanism 5 reaches a set value, the control module sends a tray 43 replacement instruction to the tray arranging mechanism 5 and its corresponding bin 4, so that the tray arranging mechanism 5 resets the tray 43 on it to the bin 4, and then takes out a new empty tray 43 from the bin 4. After the tray arranging mechanism 5 is reset, the counting unit resets the number of times of lens placement of the tray arranging mechanism 5.

[0072] Through the cooperative work of the modules of the auxiliary sorting system, the automatic sorting of the lenses is realized. From the lens feeding, detection, code recognition, classification and placement to the automatic replacement of the tray, the whole process does not need manual participation, and the work efficiency and accuracy are easily improved. At the same time, through the setting of the data acquisition module and the data processing module, the information of the lenses can be acquired and processed in real time, the position accuracy of the lenses before detection is ensured, and the detection precision is improved.

[0073] In combination with the actual needs, the above-mentioned embodiments of the present application are not limited to the scope, and various changes made within the knowledge of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
