Description

Technical Field

[0001] The present application relates to the technical field of optical lens scanning instruments, and in particular to a fully automatic lens scanner. Background Art

[0002] When dispensing optical glasses, opticians need to align the optical center of the lens with the geometric center of the frame to ensure that the image the wearer sees through the lens is clear and undistorted.

[0003] In the related technology, the contour shape of the lining is first scanned to obtain a template. After removing the lining template, the optical center position of the lens to be processed is calibrated using a focal meter or other instrument, and a mark is made on the lens to be processed to provide an accurate reference for subsequent processing and assembly. Then, the suction cup for clamping the lens is pressed onto the reference point of the lens to be processed through the clamping auxiliary equipment, and the suction cup for clamping the lens to be processed is fixed to the processing equipment, so as to perform edge grinding, polishing and other processes on the lens.

[0004] For the above-mentioned related technologies, the centering and clamping process needs to be completed manually and requires the use of at least two devices. The centering and clamping process usually involves contour scanning of the template lining, center calibration of the lens to be processed, and pressing the suction cup on the lens. Errors are prone to occur during the calibration, pressing the suction cup, and transferring the lens between the various devices. Summary of the invention

[0005] In order to improve the situation where errors are easily generated during manual centering and clamping, the present application provides a fully automatic lens scanner.

[0006] The fully automatic lens scanner provided in this application adopts the following technical solution: A fully automatic lens scanner comprises a mounting frame, an optical scanning mechanism arranged on the mounting frame and used to locate the center of the lens, and a clamping auxiliary mechanism for pressing a suction cup to attach the lens; The optical scanning mechanism comprises an upper light source lamp board arranged from top to bottom on the mounting frame, a beam splitter arranged at a 45° angle for light beams to pass through, a collimating lens assembly for deflecting light beams to form parallel light beams, a Hartmann plate located below the lens to be tested and for light beams to pass through in a matrix form, and a receiving screen for receiving a dot pattern of the lens to be tested, and the mounting frame is provided with a clamping assembly for clamping a lining sheet / lens to be tested between the collimating lens assembly and the Hartmann plate; The mounting frame is movably mounted with a diffuse reflection turntable for receiving lining contour imaging between the clamping assembly and the Hartmann plate. The mounting frame is also provided with an upper light path camera for receiving lining contour images and a lower light path camera for receiving the dot pattern on the receiving screen.

[0007] By adopting the above technical solution, the fully automatic lens scanner integrates the optical scanning mechanism and the clamping auxiliary mechanism on the same mounting frame, simplifies the equipment structure, reduces the transfer and docking links between equipment, and thus reduces the possibility of errors.

[0008] In the optical scanning mechanism, the lining sheet serving as a template is clamped by the clamping assembly, the point light source emitted by the upper light source lamp board passes through the beam splitter and forms parallel light through the collimating lens assembly, the diffuse reflection turntable moves out and rotates, the parallel light passes through the lining sheet and forms the outline of the lining sheet, the outline of the lining sheet is reflected by the diffuse reflection turntable, passes through the collimating lens assembly, and then reflected by the beam splitter to the upper light path camera, the upper light path camera records the image of the outline of the lining sheet; the diffuse reflection turntable is retracted, the lens to be tested is clamped by the clamping assembly, the point light source passes through the beam splitter and forms parallel light through the collimating lens assembly, due to the different refractive powers of the lenses to be tested, the light will be deflected to different degrees, the deflected light passes through the Hartmann plate in a matrix and forms a corresponding dot pattern on the receiving screen, the lower light path camera records the image of the dot pattern, and then calculates the refractive power and center point of the lens to be tested by using geometric relationships. The optical scanning mechanism realizes the automation of lens center positioning. Through the coordinated work of the upper light source board, beam splitter, collimating lens assembly, Hartmann plate and receiving screen, the optical center position of the lens is accurately measured without manual calibration, thus reducing human errors.

[0009] The clamping auxiliary mechanism can combine the results of geometric relationship calculation to press the suction cup to the center of the lens, which automatically assists the clamping of the lens and facilitates the optician to clamp the lens on the processing equipment for subsequent processing. The integrated setting improves work efficiency, allowing the lens to complete the entire process from center positioning to auxiliary clamping on the same equipment, reducing manual transfer and docking between equipment, thereby avoiding errors that may occur in manual operations such as inaccurate calibration and offset of the suction cup position.

[0010] Furthermore, the mounting frame includes a horizontal frame for mounting the clamping assembly and a mobile stand vertically disposed on one side of the horizontal frame and for mounting the clamping auxiliary mechanism; The clamping assembly includes a mounting base plate, a storage glass plate arranged on the mounting base plate, a clip rotatably connected to the mounting base plate and used to clamp the lining / lens to be tested, a clip driving assembly arranged on the mounting base plate and used to drive the clip to move, and a cover plate detachably connected to the mounting base plate, the mounting base plate is provided with a mounting groove for the storage glass plate to be installed and for light to pass through, and the cover plate is provided with an operating groove corresponding to the upper and lower parts of the storage glass plate.

[0011] By adopting the above technical solution, the mounting frame includes a horizontal frame and a mobile frame. The horizontal frame is used to install the main components of the clamping assembly and the optical scanning mechanism to ensure the stability and accuracy of the scanning process. The mobile frame is used to install the clamping auxiliary mechanism, which is convenient for flexible adjustment according to operational requirements. The clamping assembly includes key components such as the mounting base plate, the storage glass plate, the clip, the clip drive assembly and the cover plate. The storage glass plate is installed in the mounting groove of the mounting base plate to provide a stable support surface for the lining or the lens to be tested, allowing light to pass through, ensuring that the optical scanning mechanism can work normally. The clip is connected to the mounting base plate by rotation, and its movement is driven by the clip drive assembly to achieve a firm clamping of the lining or the lens to be tested and align it with the collimating lens, ensuring the stability and accuracy of the lens during the scanning process.

[0012] Furthermore, there are a plurality of clips and each of the clips is circumferentially arranged outside the storage glass plate, and the clip driving assembly includes a driving gear disposed on the mounting base plate and a gear ring meshed with the driving gear and used to drive each of the clips to move synchronously; The clamp has a connecting end for rotationally connecting with the mounting base plate and a clamping end for clamping the lining / lens to be tested, and the connecting end is provided with a ratchet tooth on the upper side for meshing with the gear ring.

[0013] By adopting the above technical solution, multiple clips are arranged circumferentially on the outside of the glass plate, ensuring that the lens can be subjected to uniform and stable clamping force during the clamping process, which helps to prevent the lens from being deformed or damaged due to uneven force. A ratchet structure is provided on the upper side of the connecting end of the clip, and meshes with the gear ring to achieve compactness and simplification of the clamping assembly. At the same time, the clamping assembly adopts a synchronous drive mechanism, and the synchronous opening and closing of all clips can be achieved by controlling the rotation of the active gear, thereby improving the convenience and efficiency of operation. The clamping assembly can adapt to lenses of different sizes and shapes. By adjusting the number and position of the clips, stable clamping of lenses of different specifications can be achieved.

[0014] Furthermore, a plug-in column is vertically provided on the upper side of the clamping end, and a roller for contacting the lining sheet / lens to be tested is sleeved and rotatably connected to the outside of the plug-in column.

[0015] By adopting the above technical solution, the roller is in direct contact with the lens to be tested or the lining, and the roller reduces the friction and extrusion of the lens during the clamping process through its rolling characteristics, thereby avoiding damage such as scratches, indentations or deformation of the lens caused by improper clamping.

[0016] Furthermore, a driving gear is provided on the horizontal frame, and a rack meshing with the driving gear is fixedly connected to the mounting base plate below; The clamping auxiliary mechanism includes a suction cup seat for clamping the suction cup, a driving motor for driving the suction cup seat to rotate axially, and a suction cup seat connecting block for installing the suction cup seat and the driving motor. The mobile stand is provided with a lifting drive component along the height direction for driving the suction cup seat connecting block to rise and fall, and the mobile stand is provided with a horizontal drive component along the width direction for driving the suction cup seat connecting block to move horizontally.

[0017] By adopting the above technical solution, a driving gear is provided on the horizontal frame and meshes with the rack under the mounting base plate. By rotating the driving gear, the mounting base plate and the clamping assembly thereon can be driven to move in the horizontal direction, so that the lining / lens to be tested is aligned with the clamping auxiliary mechanism. In the clamping auxiliary mechanism, the suction cup seat and the driving motor cooperate to provide power for clamping the suction cup. The suction cup seat can firmly pick up the suction cup, and the driving motor drives the suction cup seat to rotate axially, so that the suction cup is pressed onto the lens. The suction cup seat connecting block serves as the installation base of the suction cup seat and the driving motor, ensuring the stability and flexibility of the movement of the suction cup seat. The lifting drive assembly and the horizontal drive assembly enable the suction cup seat connecting block to be lifted and lowered in the height direction and to be moved horizontally in the width direction, so that the movement of the clamping auxiliary mechanism can be coordinated with the movement of the mounting base plate, so that the suction cup seat and the center position of the lining / lens are aligned.

[0018] Furthermore, the horizontal frame is slidably mounted with a rotating disk bottom plate below the movable vertical frame, the diffuse reflection rotating disk is rotatably connected to the rotating disk bottom plate, and the horizontal frame is provided with a rotating disk sliding drive assembly for driving the rotating disk bottom plate to slide below the storage glass plate.

[0019] By adopting the above technical solution, the diffuse reflection turntable can more comprehensively feedback the contour of the lining template by rotating. The turntable sliding drive assembly can drive the rotating disk bottom plate and the diffuse reflection turntable on it to slide under the object glass plate. When recording the contour of the lining, the turntable sliding drive assembly moves the diffuse reflection turntable to a suitable position under the object glass plate. When testing the lens to be tested, the turntable sliding drive assembly pushes the diffuse reflection turntable away from under the object glass plate to avoid interference with the lens test.

[0020] Furthermore, the horizontal frame is provided with a turntable drive assembly cooperating with the diffuse reflection turntable on the side away from the movable vertical frame, and the turntable drive assembly includes a rotating wheel for abutting against the diffuse reflection turntable, a rotating disk motor for driving the rotating wheel to rotate axially, and a mounting plate rotatably connected to the horizontal frame and used to install the rotating disk motor and the rotating wheel, and a buffer spring is connected between the mounting plate and the horizontal frame.

[0021] By adopting the above technical solution, the rotating disk bottom plate is not provided with a power source for the diffuse reflection turntable to rotate, and the turntable drive assembly provides power for the rotation of the diffuse reflection turntable. When the rotating disk bottom plate with the diffuse reflection turntable moves to the bottom of the storage glass plate, the edge of the diffuse reflection turntable abuts against the rotating wheel, and the rotating disk motor drives the rotating wheel to rotate axially, so that the rotating wheel and the diffuse reflection turntable are realized. The mounting plate is used to fix and support the rotating disk motor and the rotating wheel. When the edges of the diffuse reflection turntable and the rotating wheel contact each other, in order to prevent excessive extrusion between the two, the buffer spring connected between the mounting plate and the horizontal frame can play a certain buffering effect, and also play a shock absorbing role in the rotation of the diffuse reflection turntable and the rotating wheel, so as to prevent the scanning process of the lining contour from being affected.

[0022] Furthermore, the movable stand is provided with a lens rack for mounting the collimating lens assembly, and the lens rack is located above the horizontal rack; The collimating lens assembly comprises a concave lens and a convex lens which are arranged from top to bottom and abut against each other.

[0023] By adopting the above technical solution, the combination of concave lens and convex lens can achieve precise collimation of light through mutual compensation and enhancement of optical properties. The concave lens has the function of diverging light, while the convex lens has the function of converging light. When the concave lens and the convex lens are abutted against each other and installed correctly, a lens group with good light collimation effect can be formed, which helps to improve the lens scanner's ability to control and utilize light, thereby improving the accuracy and precision of the test.

[0024] Furthermore, the upper light path camera is located on one side of the collimating lens assembly, the lens frame is provided with an upper support cover for installing the upper light path camera on the side close to the movable stand, the lower light path camera is located below the receiving screen, and the horizontal frame is provided with a lower support cover for installing the lower light path camera on the lower side.

[0025] By adopting the above technical solution, the upper optical path camera is located on one side of the collimating lens assembly, and can directly capture the light processed by the collimating lens assembly, thereby accurately recording the contour of the lining. The lower optical path camera is located below the receiving screen, and the deflected light passing through the Hartmann plate in a matrix form a dot pattern on the receiving screen, which is then recorded by the lower optical path camera. The upper support cover and the lower support cover enable the upper and lower optical path cameras to be stably installed on the lens frame and the horizontal frame, so that the lens scanner can quickly and accurately complete the test task, thereby improving the test efficiency.

[0026] Furthermore, the lens frame is provided with a mirror plate fixing frame on the upper side for mounting the beam splitter, and the mirror plate fixing frame is provided with a lamp board mounting assembly on the upper side for mounting the upper light source lamp board.

[0027] By adopting the above technical solution, the beam splitter is arranged below the point light source, and the light emitted by the point light source passes through the beam splitter from top to bottom, then passes through the collimating lens and enters the lower light path camera. When the reflected light from bottom to top reaches the beam splitter position, it can be reflected by the beam splitter and enter the upper light path camera. The beam splitter allows the light to be effectively divided and guided to different paths, thereby achieving precise management and control of the light. The light board mounting assembly provides a stable and adjustable light source to ensure the intensity and stability of the light during the test.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. By integrating the optical scanning mechanism and the clamping auxiliary mechanism on the same mounting frame, the equipment structure is simplified, the transfer and docking links between devices are reduced, the work efficiency is improved through integration, and the errors caused by inaccurate docking between devices are significantly reduced; 2. The optical scanning mechanism realizes the automation of lens center positioning without manual calibration, thus reducing human errors. Through the coordinated work of the upper light source board, beam splitter, collimating lens assembly, Hartmann plate and receiving screen, the optical center position of the lens can be accurately measured. The clamping auxiliary mechanism can automatically press the suction cup to the center of the lens according to the calculation results of the geometric relationship, further improving the accuracy and efficiency of clamping. The automated setting improves the accuracy of the test and makes the entire test process more efficient and reliable; 3. The clamping assembly can adapt to lenses of different sizes and shapes. By adjusting the position of the clip, lenses of different specifications can be stably clamped. The lifting drive assembly and the horizontal drive assembly in the clamping auxiliary mechanism enable the suction cup seat connection block to be lifted and lowered in the height direction and moved horizontally in the width direction, thereby realizing flexible adjustment of the lens position. The clamping assembly can move horizontally through the driving gear on the horizontal frame and the rack under the mounting base, so that the lining / lens to be tested is aligned with the clamping auxiliary mechanism, thereby realizing accurate alignment between the clamping auxiliary mechanism and the lining / lens to be tested.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-10 And embodiments, the present application is further described in detail.

[0041] The present application embodiment discloses a fully automatic lens scanner. Figure 1 and Figure 2 The fully automatic lens scanner includes a mounting frame 1, an optical scanning mechanism 2 and a clamping auxiliary mechanism 3 arranged on the mounting frame 1. The optical scanning mechanism 2 can be used to locate the optical center of the lens, and the clamping auxiliary mechanism 3 can press the suction cup to the center position of the lens.

[0042] Reference Figure 2 and Figure 3The mounting frame 1 includes a central bottom plate 11, four support columns 12 which are dispersedly arranged and vertically fixedly connected to the central bottom plate 11, a horizontal frame 13 fixedly connected to the upper ends of the support columns 12, a mobile stand 14 installed above the horizontal frame 13, and a lens frame 15 installed on one side of the mobile stand 14, wherein a clamping assembly 16 for clamping the lens to be tested of the lining is provided on the horizontal frame 13.

[0043] Reference Figure 3 and Figure 4 The lens frame 15 is fixedly connected to a mirror plate fixing frame 151 on the upper side for mounting the beam splitter 22. In this embodiment, the mirror plate fixing frame 151 is arranged in a cone shape and the taper increases from top to bottom. The beam splitter 22 is arranged at a 45° inclination and fixedly connected to the mirror plate fixing frame 151. Figure 5 The upper end of the mirror plate fixing frame 151 is fixedly connected with a lamp board mounting assembly 211 for mounting the upper light source lamp board 21. The lamp board mounting assembly 211 includes a light source fixing seat 2111, a light source fixing cover 2112 and an upper light source cover 2113. The light source fixing seat 2111 has a slot structure for the upper light source lamp board 21 to be installed and fixed. The light source fixing cover 2112 is embedded under the light source fixing seat 2111 and has a light-transmitting hole in the middle position for the light beam to pass through. The upper light source cover 2113 is sleeved and covered on the upper end of the mirror plate fixing frame 151. The light source fixing seat 2111 is coaxially arranged and fixedly connected to the bottom of the upper light source cover 2113 by bolts and other connecting parts.

[0044] Reference Figure 3 and Figure 4 The lens frame 15 has an integrally connected mounting tube 152 and a connecting arm 153. The connecting arm 153 is vertically arranged and fixedly connected to the side of the mobile stand 14. The mirror plate fixing frame 151 is installed on the upper part of the mounting tube 152. The collimating lens assembly 23 is installed in the mounting tube 152 and is located at the lower part of the mounting tube 152. The collimating lens assembly 23 includes a concave lens 231 and a convex lens 232 with the same outer diameter. The concave lens 231 and the convex lens 232 are arranged from top to bottom and abut against each other. The collimating lens assembly 23 combines the concave lens 231 and the convex lens 232 for use, and mutually compensates and enhances each other through optical characteristics, thereby collimating the light.

[0045] An upper support cover 271 for mounting the upper light path camera 27 is fixedly connected to the mounting tube 152 on one side close to the connecting arm 153. An opening for light to pass through is provided on the side wall of the mounting tube 152. The upper light path camera 27 is mounted in the upper support cover 271. The lens of the upper light path camera 27 faces the side of the spectrometer 22 and is directly opposite to the opening position.

[0046] The lower side of the horizontal frame 13 is integrally connected with a lower connecting tube 131, and the horizontal frame 13 has an opening that is connected to the lower connecting tube 131 and allows light to pass through. A lower support cover 281 for installing the lower optical path camera 28 is fixedly connected below the lower connecting tube 131. The lower optical path camera 28 is installed in the lower support cover 281, and the lens of the lower optical path camera 28 is set upward and directly opposite to the opening position. The lower connecting tube 131 is fixedly connected to a mounting plate 251 for installing the receiving screen 25 at the opening position, and the receiving screen 25 is fixed to the top of the lower optical path camera 28 by the mounting plate 251. The Hartmann plate 24 is fixedly connected to the horizontal frame 13 by bolts and other connecting parts and is located directly above the receiving screen 25. The Hartmann plate 24 is provided with a plurality of through holes distributed in a matrix for light to pass through.

[0047] Reference Figure 6 and Figure 7 The clamping assembly 16 is arranged on the horizontal frame 13 and is located above the Hartmann plate. The clamping assembly 16 includes a mounting base plate 161, a storage glass plate 162, a clip 163 for clamping a lining or a lens to be tested, a clip 163 driving assembly for driving the clip 163, and a cover plate 165 for protecting the clip 163 driving assembly. The mounting base plate 161 is mounted on the upper side of the horizontal frame 13 and is used for mounting other components. The mounting base plate 161 is provided with a mounting groove for mounting the storage glass plate 162 and for light to pass through. The storage glass plate 162 is located just above the receiving screen 25. In this embodiment, the number of the clips 163 is three. Each clip 163 is circumferentially arranged and evenly spaced on the periphery of the storage glass plate 162. Each clip 163 is rotatably connected to the mounting base plate 161.

[0048] The driving assembly of the clip 163 includes a driving gear 1641 fixedly connected to the mounting base 161 and a toothed ring 1642 meshed with the driving gear 1641. In this embodiment, the clip 163 has a connecting end 1631 for rotationally connecting with the mounting base 161 and a clamping end 1632 for clamping the lining or the lens to be tested. The connecting end 1631 is provided with a ratchet 16311 for meshing with the toothed ring 1642 on the upper side. The clamping end 1632 extends between the toothed ring 1642 and the object placement glass plate 162 to clamp the lining or the lens to be tested placed on the object placement glass plate 162. The driving gear 1641 is driven by the motor on the lower side of the mounting base 161, and the toothed ring 1642 is driven by the driving gear 1641 to rotate axially. The three clips 163 are driven by the toothed ring 1642 through the ratchet 16311, respectively, so that the three clamping ends 1632 are close to or away from each other.

[0049] A micro switch 166 for cooperating with the clip 163 is provided on the mounting base 161. The micro switch 166 is mounted on a side of the mounting base 161 close to the mobile stand 14. The micro switch 166 is electrically connected to the motor of the driving gear 1641. When the clip 163 close to the mobile stand 14 is driven by the gear ring 1642 to rotate to abut against the micro switch 166, the micro switch 166 is triggered, thereby cutting off the operation of the driving gear 1641, preventing the clip 163 from being continuously driven, opening too much, or causing excessive compression on the lining / lens.

[0050] Each clip 163 is vertically arranged on the upper side of the clamping end 1632 and is integrally connected with a plug-in column 16321. A roller 16322 for contacting the lining sheet / lens to be tested is sleeved and rotatably connected to the outside of the plug-in column 16321. A roller 16322 cap is arranged above the roller 16322. The roller 16322 cap is fixedly connected to the plug-in column 16321 to prevent the roller 16322 from falling off. The roller 16322 is in direct contact with the lens to be tested or the lining sheet. Through its rolling characteristics, the friction and extrusion of the lens during the clamping process are reduced, thereby avoiding scratches, indentations or deformation of the lens caused by improper clamping.

[0051] The cover plate 165 is detachably connected to the mounting base plate 161 by means of bolts, nuts and other connecting parts, and the cover plate 165 can protect the driving assembly of the clip 163, thereby preventing the tooth ring 1642 from being separated from each ratchet 16311. The cover plate 165 is provided with operating grooves 1651 corresponding to the upper and lower sides of the placement glass plate 162, and the operator can place the lining or the lens to be tested on the placement glass plate 162 through the operating grooves 1651, and then control the clip 163 to perform the clamping action.

[0052] The diffuse reflection turntable 26 is horizontally arranged and slidably installed between the mounting base plate 161 and the Hartmann plate 24 to receive the contour imaging of the lining. A rotating disk base plate 261 for mounting the diffuse reflection turntable 26 is slidably installed on the horizontal frame 13, and the diffuse reflection turntable 26 is rotatably connected to the rotating disk base plate 261. The horizontal frame 13 is provided with a turntable sliding drive assembly 262 for driving the rotating disk base plate 261 to slide under the object placement glass plate 162. The turntable sliding drive assembly 262 includes a gear installed on the horizontal frame 13 and driven by a motor, and a rack 133 installed under the rotating disk base plate 261 and meshing with the gear.

[0053] Reference Figure 7 and Figure 8The horizontal frame 13 is provided with a turntable drive assembly 263 matched with the diffuse reflection turntable 26 at a side away from the mobile stand 14. The turntable drive assembly 263 includes a mounting plate 2631, a rotating wheel 2632 for contacting the diffuse reflection turntable 26, and a rotating disk motor 2633 for driving the rotating wheel 2632 to rotate axially. One side of the mounting plate 2631 is rotatably connected to the horizontal frame 13, the rotating disk motor 2633 is fixedly connected to the side of the mounting plate 2631 below and away from the horizontal frame 13, and the rotating wheel 2632 is mounted on the rotating disk motor 2633 and is located above the mounting plate 2631. When the rotating disk bottom plate 261 moves with the diffuse reflection turntable 26 below the storage glass plate, the edge of the diffuse reflection turntable 26 abuts against the rotating wheel 2632, and the rotating disk motor 2633 drives the rotating wheel 2632 to rotate axially, thereby realizing rotation transmission between the rotating wheel 2632 and the diffuse reflection turntable 26.

[0054] A buffer spring 2634 is connected between the mounting plate 2631 and the horizontal frame 13. When the edges of the diffuse reflection turntable 26 and the rotating wheel 2632 come into contact with each other, in order to prevent excessive squeezing between the two, the buffer spring 2634 connected between the mounting plate 2631 and the horizontal frame 13 can play a certain buffering effect. At the same time, it also plays a shock-absorbing role in the rotation of the diffuse reflection turntable 26 and the rotating wheel 2632, thereby preventing the scanning process of the lining contour from being affected.

[0055] The horizontal frame 13 is provided with a driving gear 132, and the mounting base plate 161 is fixedly connected to a rack 133 meshing with the driving gear 132. The rotation of the driving gear 132 can drive the mounting base plate 161 and the clamping assembly 16 thereon to move forward and backward on the horizontal frame 13, so that the lining sheet / lens to be tested on the placement glass plate 162 is aligned with the clamping auxiliary mechanism 3.

[0056] Reference Fig. 9 and Fig.10 The clamping auxiliary mechanism 3 includes a suction cup seat 31, a drive motor 32, a suction cup seat 31 connection block, a lifting drive assembly 34 and a horizontal drive assembly 35.

The suction cup seat 31 is arranged downward, and the drive motor 32 is used to drive the suction cup seat 31 to rotate axially so that the suction cup seat 31 can clamp / release the suction cup.

[0057] The horizontal driving assembly 35 includes a horizontal guide rail 351, a horizontal sliding block 352, a horizontal driving gear 353 and a horizontal rack 354. The horizontal guide rail 351 is arranged along the width direction of the mobile stand 14 and is fixedly connected to the mobile stand 14. The horizontal sliding block 352 is slidably installed on the horizontal guide rail 351.

[0058] The lifting drive assembly 34 includes a lifting rail 341, a motor screw 342, a Z-axis nut 343, and a lifting support block 344. The lifting rail 341 is fixedly connected to a side of the horizontal sliding block 352 away from the horizontal rail 351, a horizontal rack 354 is horizontally arranged and fixedly connected to the lower end of the lifting rail 341, a horizontal driving gear 353 is installed on the mobile stand 14 and meshes with the horizontal rack 354, and the horizontal driving gear 353 is driven by the motor to drive the lifting rail 341 to move horizontally left and right on the mobile stand 14.

[0059] The motor screw 342 is installed on one side of the lifting rail 341, the Z-axis nut 343 is threadedly matched with the motor screw 342, and the lifting support block 344 is slidably installed on the lifting rail 341 and fixedly connected to the Z-axis nut 343. The connection block of the suction cup seat 31 is fixedly connected to the front side of the lifting support block 344. The suction cup seat 31 is driven by the lifting drive assembly 34 and the horizontal drive assembly 35 to achieve left and right translation and lifting, so as to be aligned with the position of the lining / lens to be tested.

[0060] The implementation principle of a fully automatic lens scanner in the embodiment of the present application is as follows: an installation frame 1 is used as the basic support structure of the scanner, including a central base plate 11, a support column 12, a horizontal frame 13, a movable stand 14 and a lens frame 15, etc., to ensure that each component is stably and accurately installed; the optical scanning mechanism 2 integrates an upper light source lamp board 21, a spectroscope 22, a collimating lens assembly 23, a Hartmann plate 24, a receiving screen 25, a diffuse reflection turntable 26, an upper light path camera 27 and a lower light path camera 28, etc., for realizing the optical center positioning and optical property measurement of the lens; the clamping auxiliary mechanism 3 includes a suction cup seat 31, a drive motor 32, a suction cup seat 31 connecting block, a lifting drive assembly 34 and a horizontal drive assembly 35, which are used to accurately press the suction cup to the center of the lens for subsequent processing.

[0061] First, the clamping assembly 16 clamps the lining, and the upper light source emits a point light source, which forms parallel light through the beam splitter 22 and the collimating lens assembly 23. The diffuse reflection turntable 26 receives and reflects the outline of the lining to the upper light path camera 27 to complete the recording of the outline of the lining. Subsequently, the clamping assembly 16 clamps the lens to be tested, and the point light source forms parallel light again. The light is deflected by the lens and forms a dot pattern through the Hartmann plate 24, which is recorded by the lower light path camera 28, and the lens diopter and center point are calculated through geometric relationships. The clamping auxiliary mechanism 3 realizes the precise movement and lifting of the suction cup seat 31 through the coordinated work of the lifting drive assembly 34 and the horizontal drive assembly 35, ensuring that the suction cup is accurately pressed against the center of the lens. The optical scanning mechanism 2 and the clamping auxiliary mechanism 3 are integrated on the same mounting frame 1, which simplifies the equipment structure, reduces the transfer and docking links, and reduces errors.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
