Fig. 1 shows a schematic configuration diagram of an eyeglass detecting apparatus according to an exemplary embodiment. As shown in fig. 1, the eyeglass detecting apparatus 100 includes first main rails (i.e., Y-direction jig rails) 111, 121 extending in the Y-axis direction; first sub-rails (i.e., X-direction jig rails) 112, 122 mounted on the corresponding Y-

direction jig rails

111, 121 and extending in the X-axis direction; and

jigs

113, 123 mounted on the X-direction

jig guide rails

112, 122.

The X-direction

jig guide rails

112, 122 are movably mounted on the Y-direction

jig guide rails

111, 121, so that the X-direction

jig guide rails

112, 122 can reciprocate on the Y-direction

jig guide rails

111, 121 in the Y-axis direction.

In the embodiment, the Y-direction

jig guide rails

111 and 121 may be mounted on a flat and non-deformable mounting base plate 150, for example. The eyewear detection apparatus 100 may also include

control switches

114, 124. The

control switches

114 and 124 are used for controlling the reciprocating motion of the X-direction

jig guide rails

112 and 122 on the Y-direction

jig guide rails

111 and 121 along the Y-axis direction, respectively. The

control switches

114, 124 may be disposed, for example, at ends of the Y-

direction jig rails

111, 121, respectively.

The

jigs

113, 123 are configured such that glasses to be detected (e.g., AR glasses, not shown in fig. 1) can be placed on the

jigs

113, 123, respectively, in a direction parallel to the X-axis direction. For example, one AR glasses may be placed on the jig 113 in a direction parallel to the X-axis direction so that two lenses of the AR glasses are arranged side by side in the direction parallel to the X-axis direction; another piece of AR glasses may be placed on the jig 123 in a direction parallel to the X-axis direction so that the two lenses of the AR glasses are arranged side by side in the direction parallel to the X-axis direction.

In an embodiment, the

jigs

113, 123 are movably mounted on the X-direction

jig guide rails

112, 122 such that the

jigs

113, 123 can reciprocate on the X-direction

jig guide rails

112, 122 in the X-axis direction.

As shown in fig. 1, the eyeglass detecting apparatus 100 further includes second rails (i.e., cross rails) 131, 141 and detecting

devices

132, 142 mounted on the

cross rails

131, 141. The

lateral rails

131, 141 are disposed above the Y-

direction jig rails

111, 121, the

X-direction jig rails

112, 122, and the jigs 113, 123 (and optionally the AR glasses to be placed on the jigs 113, 123) in a suspended manner, and extend parallel to the X-axis direction.

Each of the

lateral rails

131, 141 may be supported on the mounting base plate 150, for example, by

support bars

133, 143 on both sides thereof, so as to be at a height above the

jigs

113, 123. The support bar 133 may include two bars located on both sides of the cross rail 131. The support bar 143 may include two bars located on both sides of the cross rail 141.

In an embodiment, the

support rods

133, 143 may be, for example, liftable support rods. The lifting

support rods

133 and 143 can be respectively sleeved with corresponding

lifting driving devices

134 and 144. Specifically, the lifting driving device 134 may be disposed on the outer side of the supporting rod 133, and the lifting driving device 144 may be disposed on the outer side of the supporting rod 134.

The height of the liftable support bars 133, 143 can be adjusted by the lifting

drive devices

134, 144 fitted around the outer peripheries of the support bars 133, 143, thereby correspondingly adjusting the cross rails 131, 141 to a desired height.

According to an embodiment, the cross rail 131 may be connected to the elevation driving means 134, or may be integrally formed with the elevation driving means 134. For example, the lateral guide 131 may be formed between the elevation driving means 134 fitted around the outer circumference of the support bar 133 formed as two bars. The cross rail 131 may be integrally formed with the elevation driving means 134 fitted around the outer circumference of the support bar 133 formed as two bars. According to an embodiment, the cross rail 141 may be connected to the elevation driving means 144, or may be integrally formed with the elevation driving means 144. For example, the lateral guide 141 may be formed between the elevation driving means 144 fitted around the outer circumference of the support bar 143 formed as two bars. The transverse rail 141 may be integrally formed with the elevation driving means 144 fitted around the outer circumference of the support bar 143 formed as two bars. Thus, the lifting

drive devices

134, 144 can be used as driving members, and the

transverse guide rails

131, 141 can be used as driven members, so that the movements of the two can be synchronized.

By moving the X-direction jig rails 112, 122 in the Y-axis direction on the Y-direction jig rails 111, 121, the

jigs

113, 123 and the AR eyeglasses placed on the

jigs

113, 123 can be moved in the Y-axis direction to be located below the

lateral rails

131, 141. When the AR glasses are located below the

lateral rails

131, 141, the

detection devices

132, 142 have a certain distance in the Z direction from the jigs 113, 123 (the AR glasses placed on the jigs 113, 123).

It should be understood that although two sets of jig guide assemblies (including Y-direction jig guide rails, X-direction jig guide rails, and jigs) and two sets of cross-guide assemblies (including cross-guide rails, support rods, and lift drives) are shown in fig. 1, the eyeglass inspection apparatus 100 according to the present application may include only one set of jig guide assemblies and one set of cross-guide assemblies, and may include more sets of jig guide assemblies and many sets of cross-guide assemblies.

Also, although one detection device is shown to be provided on each cross rail in fig. 1, a plurality of detection devices may be provided on each cross rail according to the eyeglass detection apparatus 100 of the present application.

According to an embodiment, the cross-rail assembly as shown in fig. 2 includes a cross-rail 231, a detection device (e.g., including a spectrometer 232-1, a camera 232-2, and other detection components 232-3), a liftable support bar 233, a lifting drive 234, and a cross-drive 235. According to an exemplary embodiment, the cross-rail assembly as shown in FIG. 2 may further include a structural member 236 and a locking member 237.

The cross rail assembly including the cross rail and the detecting device is fixed to a mounting base plate (e.g., the mounting base plate 150 in fig. 1) by a fixing member 237 at the bottom of the liftable supporting rod 233, using the liftable supporting rod 233 as a base. The liftable supporting rod 233 may be, for example, a regular cylinder, and the lifting driving device 234 may be sleeved on the periphery of the liftable supporting rod 233. The elevating driving means 234 moves up and down along the elevating support bar 233. For example, when the elevation driving devices 234 on both sides are synchronously moved up and down, the control cross rail 231 is moved up and down (i.e., moved in the Z-axis direction) together therewith. The up and down movement of the cross-rail 231 may cause the detection device (e.g., including the spectrometer 232-1, the camera 232-2, and other detection components 232-3) disposed on the cross-rail 231 to move up and down in synchronization therewith. Therefore, the relative distance between the detection device and the AR glasses on the jig is changed. The detection device may include, for example, a spectrometer 232-1, a camera 232-2, or other desired detection components 232-3 such as a laser altimeter. That is, an appropriate detecting member can be selected and installed on the lateral rail according to the required function for performing corresponding detection on the AR glasses.

According to an embodiment, the detecting device 232 disposed on the cross rail 231 may be movably disposed on the cross rail 231 by a cross driving device 235. The transverse driving device 235 is reciprocally movable along the transverse rail 231 in the X-axis direction, thereby controlling the detecting device to reciprocally move along the transverse rail 231 to achieve the position adjustment of the detecting device in the X-axis direction.

As shown in the drawing, a spectrometer 232-1 and a camera 232-2 as detection parts are respectively disposed on both sides of the cross rail 231. Therefore, it should be understood that two lateral driving devices 235 may be provided to drive the spectrometer 232-1 and the camera 232-2 disposed at both sides of the lateral guide 231 in the X-axis direction, respectively. Alternatively, a lateral driving device 235 may be provided to simultaneously drive the spectrometer 232-1 and the camera 232-2 disposed at both sides of the lateral guide 231 in the X-axis direction.

In the case of having a plurality of detection parts (e.g., including the spectrometer 232-1, the camera 232-2, and the other detection parts 232-3), the plurality of detection parts and their lateral driving means may be disposed at intervals back and forth to be arranged to fully utilize the longitudinal space of the apparatus so that the apparatus can simultaneously detect a plurality of AR glasses. The front and rear detecting members (for example, two identical or different detecting members) can be operated at the same time to improve the production efficiency of the whole apparatus.

In an embodiment, the liftable support rod 233 and the lifting driving device 234 may be connected by any suitable connection method, such as worm gear, cylinder driving, etc.

In order to ensure the structural stability, a structural member 236 for connecting the two side support rods may be provided at the top end portion of the liftable support rod 233.

Fig. 3 illustrates a jig assembly according to an exemplary embodiment.

As shown in fig. 3, the jig assembly includes a six-axis adjusting platform 311 and a jig 310 fixed on the six-axis adjusting platform 311. That is, the jig 310 is fixed on the X-direction jig guide rail movably connected to the Y-direction jig guide rail by the six-axis adjustment platform 311.

The six-axis adjustment stage 311 has a plurality of adjusters 312 (e.g., adjustment knobs) thereon, which can adjust the spatial position of the six-axis adjustment stage, and by which the spatial state of the six-axis adjustment stage, that is, the state of the upper surface of the six-axis adjustment stage, can be adjusted. Since the jig 310 is fixed on the upper surface of the six-axis adjustment platform 311, the spatial state of the jig 310 can be adjusted by the adjuster 312 (e.g., an adjustment knob). For example, the position of the jig 310 can be adjusted in terms of height, angle, inclination, etc. by the adjuster 312, so that the jig 310 is disposed at a desired position in various directions, so as to detect the AR glasses placed on the jig 310. When the AR glasses are placed on the jig 310, the spatial form of the AR glasses may be changed when the spatial form of the jig 310 is changed according to the adjustment of the adjuster 312. That is, the spatial state of the AR glasses may be brought close to or in an ideal detection state by the adjuster 312.

Fig. 4 illustrates a block diagram of AR glasses according to an exemplary embodiment. The AR glasses as shown in fig. 4 include a glasses body 410 and light guide assemblies 420 located at both sides of the glasses body 410. According to an embodiment, the glasses body 410 may include lenses 411 and a supporter 412 disposed between the two lenses 411. The light guide assembly 420 is disposed corresponding to the lens 411 at both sides of the support 412 to transfer image information to the lens 411.

According to the embodiment, the light guide assembly 420 has a turning light path therein, and the turning light path can transmit the image information projected by the chip assembly 430 connected to the end of the light guide assembly 420 to the lens 411 through the conduction of the light guide assembly 420 and the primary light path turning of the reflection surface 421 of the light guide assembly 420. The arrows in fig. 4 show that an exemplary chip assembly 430 with an optical path 440 disposed at the end of the light guide assembly 420 has a connector 431 at the end remote from the light guide assembly 420. The connector 431 is oriented in the same direction as the temple of the conventional eyeglasses. That is, the lens 411 may face upward when the connector 431 is oriented downward. Thus, when the AR glasses are placed on the jig, the chip assembly 430 is located at both sides of the jig, and the connector 431 of the chip assembly 430 is disposed downward (or vertically downward, as it is), so that an external power supply device (e.g., a connector electrical connection device) or an electrical connection between an electrical wire and the connector 431 on the chip assembly 430 is easily disposed. Meanwhile, the AR glasses with the downward connector 431 are convenient to place on the jig, and the design concept of convenience in operation and stability is met. Under the influence of gravity, the form that AR glasses were placed on the tool is a stable form, and when AR glasses were in this form simultaneously, just in time chip component 430 was towards the below, lens 411 was towards the top, had both made things convenient for the electric conductance to be led to, had made things convenient for the quality of extremely up and down with detection device to AR glasses again to detect.

Fig. 5 exemplarily shows a mounting state of the AR eyeglasses on the jig.

As shown in fig. 5, the jig 540 includes a glasses placement boss 541 and a connector electrical connection device 542. It should be understood that although the connector electrical connection device is described herein as being part of a fixture. Alternatively, however, the connector electrical connection device may be a separate component from the fixture 540.

The glasses placement bosses 541 are adapted to contact and support a mid-section portion of the AR glasses. For example, the glasses placement bosses 541 may be provided as the carrying portions 512 for supporting the AR glasses, so that the AR glasses have a stable mounting structure but have a certain overhead so that the lenses 511 do not directly contact the surface of the jig 540. Therefore, the lens 511 is prevented from being damaged by contacting the fixture 540 or other physical structures. As described above, when the AR glasses are placed on the glasses placement bosses 542, the chip assembly 530 is placed downward while naturally and stably hanging down based on gravity, whereby the circuit board of the chip assembly 530 is also leveled without wrinkles. The connector 531 at the end of the chip assembly 530 and the connector electrical connection means 542 at both sides of the jig 540 may be positioned close to each other, and the connector 531 may be electrically connected to the connector electrical connection means 542, thereby achieving electrical conduction of the entire AR glasses. At this time, the lens 511 of the AR glasses is upward, which is beneficial to the detection of the AR glasses from top to bottom by the detection device arranged above the AR glasses.

According to the embodiment, when the AR glasses are detected, the X-direction jig guide rail for placing the jig and/or the jig for placing the AR glasses need to be conducted so as to drive in the Y-axis direction. Therefore, according to an embodiment, the glasses inspection apparatus further comprises a line fixing device for placing an electric wire to be electrically connected with at least one of the AR glasses, the jig, and the X-directional jig guide. According to the embodiment, because X to the tool guide rail, place tool on X to the tool guide rail and place AR glasses on the tool and can carry out the motion of great stroke along Y to the tool guide rail, therefore the mode of traditional acting as go-between is not applicable to the glasses check out test set of this application. According to an embodiment, a tank chain can be adopted as a line fixing device of the glasses detection equipment according to the application.

According to an exemplary embodiment, the glasses inspection apparatus includes Y-direction jig rails 611, 621, X-direction jig rails 612, 622 installed on the Y-direction jig rails 611, 621,

jigs

613, 623 installed on the X-direction jig rails 612, 622, control switches 614, 624 for controlling movement of the X-direction jig rails 612, 622 on the Y-direction jig rails 611, 621, and

line fixing devices

615, 625. As shown in fig. 6, the line fixture 615 is connected to the X-direction jig guide 612, and the line fixture 625 is connected to the jig 623. It should be understood that the line fixture may be connected to at least one of the corresponding X-direction jig guide rail and jig. For example, the

line fixtures

615, 625 may be connected to corresponding X-direction jig rails 612, 622, respectively. Optionally, the

line fixing devices

615 and 625 may also be connected to the corresponding

jigs

613 and 623, respectively.

As shown in fig. 6, the

line fixtures

615, 625 may be implemented by tank chains having line fixing spaces inside. The inside circuit fixed space that has of tank chain, the conducting wire can be restrainted inside the tank chain. The chain structure of the tank chain makes it possible to bend and spread relatively regularly so that the line fixing device can bend and spread along the Y-direction

jig guide rails

611, 621. Therefore, the problem of line arrangement when the moving part moves in a large stroke is solved, and meanwhile, the arrangement in the equipment is kept regular and not messy.

According to the embodiment, the jig can be changed in position in the XY plane by reciprocating the X-direction jig guide rail along the Y-direction jig guide rail and by reciprocating the jig along the X-direction jig guide rail.

After the AR glasses are placed on the jig and powered on, the motion control program is started through the control switch, so that the X-direction jig guide rail moves towards the inside of the equipment along the Y-direction jig guide rail, namely, moves towards the direction close to the detection device. After the X-direction jig guide moves to a predetermined position (i.e., a position substantially directly below the detection device), the position of the jig and/or the detection device in the X-axis direction may be further adjusted to substantially align the two. Further, the AR glasses may be powered through the connector of the chip assembly of the AR glasses by, for example, a connector electrical connection device.

In the above-described embodiments, the jig for placing the AR glasses is mounted on the X-direction jig guide rail, and the X-direction jig guide rail is mounted on the Y-direction jig guide rail. The transverse guide rail is arranged above the Y-direction jig guide rail, the X-direction jig guide rail and the jig in a suspended manner. The detection device is arranged on the transverse guide rail. In order to detect the glasses, the jig and the X-direction jig guide rail for placing the jig reciprocate in the Y-axis direction along the Y-direction jig guide rail. The jig reciprocates along the X-axis direction on the X-direction jig guide rail, and/or the detection device reciprocates along the X-axis direction on the transverse guide rail.

In other embodiments, the X-direction jig guide may be omitted.

In this case, the eyeglass detecting apparatus includes a Y-direction jig guide rail extending in the Y-axis direction, a jig mounted on the Y-direction jig guide rail, a cross guide rail extending in the X-axis direction above the Y-direction jig guide rail and the jig, and a detecting device mounted on the cross guide rail. The jig can be directly installed on the Y-direction jig guide rail without being indirectly arranged on the Y-direction jig guide rail through the X-direction jig guide rail. Under the control of the control switch, the jig can reciprocate along the Y-axis direction on the Y-direction jig guide rail. The jig is configured such that the eyeglasses to be detected can be placed on the jig parallel to the X-axis direction. Specifically, when the eyeglasses to be detected are placed on the jig, two lenses of the eyeglasses are arranged side by side in the X-axis direction.

When the jig moves to a preset position along the Y-direction jig guide rail under the driving of the control switch, the jig is approximately aligned with the transverse guide rail arranged above the jig in a suspended manner in the Y-axis direction. In this case, the detection device mounted on the transverse rail may be driven, for example, by the transverse driving device, so that the detection device mounted on the transverse rail is moved in the X-axis direction into approximate alignment with the eyeglasses to be detected placed on the jig, thereby detecting the eyeglasses as needed. For example, a detection device mounted on a transverse rail may be moved in the X-axis direction into alignment with one of the lenses of the eyeglasses to be detected.

According to the implementation method, the glasses detection equipment can further comprise a lifting support rod and a lifting driving mechanism. The transverse guide rail can be supported by a lifting support rod and can move up and down to a proper height under the driving of a lifting driving mechanism.

It should be understood that, in this embodiment, other technical features in the above-described embodiment can be applied to the present embodiment, except for omitting the X-direction jig guide. Therefore, the description of some technical features is omitted here.

Fig. 7 shows a flowchart of a method of detecting glasses using a glasses detection apparatus according to an exemplary embodiment.

As shown in fig. 7, in step 701, the glasses to be detected are placed on a jig. Specifically, place glasses on the glasses detection boss of tool, make its chip subassembly down, make its lens up and the lens does not contact with the tool.

At step 702, a fixture may be moved to a predetermined position in a first direction (e.g., Y-axis direction). For example, the jig may be mounted on a Y-direction jig guide rail extending in the Y-axis direction. Through the control switch, the jig can be controlled to move to a preset position on the Y-direction jig guide rail along the Y-axis direction. Optionally, the jig may also be mounted on an X-direction jig guide rail extending in the X-axis direction, and an X-direction jig guide rail extending in the X-axis direction may be mounted on a Y-direction jig guide rail extending in the Y-axis direction. That is, the jig is installed on the Y-direction jig guide rail through the X-direction jig guide rail. In this case, the X-direction jig guide rail may be moved in the Y-axis direction along the Y-direction jig guide rail by, for example, driving of the control switch, thereby driving the jig mounted thereon to move in the Y-axis direction together. According to an embodiment, the jig can be moved in the Y-axis direction to be substantially aligned with the cross rail provided overhead in suspension. The transverse guide rail can be arranged at a certain height above the jig and extends along the Z direction. Various detection devices for detecting the glasses can be installed on the transverse guide rail. The height of the transverse rails can be adjusted, for example, by means of a lifting drive, so that the detection devices mounted on the transverse rails are at a suitable height for detection.

In step 703, the fixture can be moved along the X-axis direction and/or the detection device can be moved along the X-axis direction, so that the glasses placed on the fixture are located at the detection position. For example, in the case where the jig is movably mounted on the X-direction jig guide, either or both of the jig and the detection device may be moved in the X-axis direction. Under the condition that the jig can not move along the X-axis direction, the detection device can move along the X-axis direction. In particular, the detection device may be moved along a transverse rail. For example, by the lateral movement described above, the first lens of the eyewear may be brought into a detection position (e.g., aligned with the detection device).

At step 704, the first lens at the inspection position is inspected using the inspection device. The detection device may include, for example, one or more of a spectrometer, a camera, a laser altimeter, and other devices for detecting the optical performance of the eyeglass lens. The detection device may, for example, detect one or more of spectral, imaging, height and other optical properties of the eyewear.

After the first lens is inspected, similar steps as in

steps

703 and 704 may be repeated, and the jig is moved further in the X-axis direction and/or the inspection device is moved in the X-axis direction so that the second lens of the pair of eyeglasses placed on the jig is in the inspection position, and the inspection device is used to position the second lens in the inspection position. From this, detection equipment and the one-time installation of glasses can accomplish binocular detection.

If detect the left lens earlier at above-mentioned in-process, then detect the right lens after further moving, then, when detecting the next glasses of placing on this tool, when waiting to detect glasses and moving to the cross rail below, the position of its right lens in X axle direction can be corresponding to the position of detection device in X axle direction, consequently can detect the right lens at first, then detect the left lens after further moving. Therefore, the stroke of the detection device is greatly reduced, the production efficiency is improved, and the precision is improved. Optionally, the detection device may also reset all of the glasses after the detection of one of the glasses is completed, and then completely repeat the previous detection state.

As described above, there may be a plurality of detection devices mounted on the cross rail, for example, the plurality of detection devices may be at the same position in the X-axis direction and be offset from each other in the Y-axis direction (as shown in fig. 2). Therefore, the detection of a plurality of items can be completed in one detection process, and the detection of the items can be completed according to the actual requirements by combining and arranging different detection components, such as uniformity, image contrast, distortion, FOV, SFR, brightness and the like of AR (binocular, left and right eye) glasses imaging.

According to an embodiment, the transverse guide rail may also have two sets of detection devices for simultaneously detecting two lenses of a pair of glasses. In this case, the jig and/or at least one of the two sets of detection devices is moved laterally so that the two lenses of the eyeglasses are respectively in the detection positions corresponding to the two sets of detection devices. Therefore, two lenses of one pair of glasses can be detected simultaneously.

According to an embodiment, the driving means (lateral driving means) of the detection means may have distance detection or sensing means, capable of calculating the interpupillary distance of the two lenses during the detection process. Figure 8 shows a schematic diagram of the optimal interpupillary distance and the interpupillary distance extrema according to an exemplary embodiment. In the detection process, within a lens range, there is first a predetermined detection position, but the position of the lens with the best effect can be detected by adjusting the position of the detection device in the X direction, and the position can be recorded as X₁Then, the best effect position of another lens is detected to be X in the same way₂By X₁、X₂The optimal interpupillary distance of the actual product is calculated instead of the theoretical interpupillary distance alone.

In the same way, can record singleTwo extreme effect positions of the lens on either side of the frame in the direction of the X-axis, i.e. respectively X away from the center of the frame_{Right maximum value}And X_{Left maximum value}Calculating the maximum pupil distance according to the maximum values of the two; two extreme positions close to the center of the spectacle frame can also be recorded as X_{Minimum value of right}And X_{Left minimum value}Therefore, the minimum value of the actual interpupillary distance is calculated without being limited to the theoretical value planned in the production design, and the precision and the fine classification of product inspection are improved.

As described above, the glasses inspection apparatus may include a plurality of jigs and corresponding jig guide rails, so that a plurality of glasses may be inspected. In this case, an appropriate number of detection devices (each detection device may include one or more detection components, such as spectrometer 232-1, camera 232-2, and other detection components 232-3 shown in FIG. 2) may be mounted on the cross-rail. For example, only one detection device may be included, and the plurality of eyeglasses are detected one by movement of the detection device. For example, a number of detection devices corresponding to the number of jigs may be included, so that each detection device detects the glasses mounted on the corresponding jig. For example, twice the number of detection devices may be included, such that each detection device detects each corresponding lens of the eyeglasses mounted on each fixture. It should be understood that the number of detection means is not limited thereto. According to an embodiment, these detection means may be mounted on the same transverse rail. Alternatively, at least some of these detection devices may be mounted on different transverse rails. That is, an eyewear detection apparatus according to the present application may include one or more lateral rails, each of which may include one or more detection devices thereon, each of which may include one or more detection components (e.g., spectrometer 232-1, camera 232-2, and other detection components 232-3 shown in FIG. 2).

According to an embodiment, the detection of only one lens, two lenses of one spectacle, or a plurality of lenses of a plurality of spectacles can be realized by one detection device with one installation of the spectacles to be detected.

In the above description, the movement of the jig and the detection device is described using the X-axis, Y-axis, and Z-axis directions perpendicular to each other. Alternatively, however, the X-axis direction and the Y-axis direction may not necessarily be perpendicular to each other. For example, the X-direction jig guide rail may form a certain angle with the Y-direction jig guide rail but not be perpendicular, thereby saving the lateral space of the glasses inspection apparatus.
