Description

Technical Field

[0001] The present invention relates to the technical field of industrial detection, and in particular to a three-dimensional detection device for the contour of a glasses frame. Background Art

[0002] Existing eyeglass frame edge detection devices can often only obtain the contour curve of the inner groove of the eyeglass frame. This contour curve can only characterize the contour direction of the eyeglass frame edge, and cannot obtain the detailed three-dimensional morphological contour data of the inner groove of the eyeglass frame. For example, when the cross-section of the inner groove of the eyeglass frame is a V-shaped structure (or a C-shaped inner groove structure), the existing eyeglass frame edge detection device can only obtain the contour trajectory of the vertices of the V-shaped structure of the inner groove of the eyeglass frame, and cannot obtain the V-shaped cross-sectional characteristics of the entire V-shaped groove, that is, it cannot obtain the three-dimensional morphological contour data of the V-shaped groove.

[0003] After the existing eyeglass frame edge detection device guides the cutting of the lens, the lens assembler often needs to repeatedly compare the matching degree between the edge of the lens and the inner groove of the frame when installing the lens into the corresponding eyeglass frame. However, it is often necessary to manually use an edge grinder to grind the edge of the corresponding lens according to the shape of the inner groove of the frame so that the lens can be better installed in the frame. However, this manual judgment of the matching degree between the lens and the inner groove of the frame, and the manual use of an edge grinder to grind the edge of the lens, these two processes often test the experience and patience of the lens assembler. This also causes this process to be time-consuming, which is not conducive to saving labor costs.

[0004] Figure 1 The structure of the glasses frame is shown, 901 represents the contour curve of the inner groove of the glasses frame, and 900 represents the cross section of the inner groove of the glasses frame at a point on the contour curve of the inner groove of the glasses frame. Summary of the invention

[0005] The purpose of the present invention is to provide a three-dimensional detection device for the contour of a glasses frame, so as to solve the problem that the existing detection device cannot obtain the three-dimensional shape contour of the inner groove of the glasses frame.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] Provided is a three-dimensional detection device for the outline of an eyeglass frame, comprising an OCT imaging module and a tracking pen module, wherein the OCT imaging module comprises an OCT light source, a fiber coupler, a probe module, a reference arm module, and a detector, wherein the probe module comprises a rotating probe, a folding prism, and a driving device, wherein the rotating probe can rotate around the main optical axis of the probe module, the folding prism is used to fold light, and the driving device is used to drive the rotating probe to rotate along the main optical axis of the probe module, and the tracking pen module comprises a tracking pen, wherein the rotating probe, the folding prism, and the tracking pen module are connected in sequence, and the main optical axis of the folding prism is arranged parallel to the tracking pen;

[0008] The probe module moves with the tracking pen, and its moving trajectory is the same as the contour curve of the inner groove of the eyeglass frame, thereby obtaining one dimension of the OCT three-dimensional imaging; the rotating probe rotates around the main optical axis of the rotating probe, and the scanning light emitted from the rotating probe rotates around the main optical axis of the rotating probe. After being reflected by the folding prism, the scanning light is folded in direction, thereby obtaining the other two dimensions of the OCT three-dimensional imaging.

[0009] In some embodiments, the folding prism is a Porro prism.

[0010] In some embodiments, the folding prism is connected to the tracking pen.

[0011] In some embodiments, the tracking pen module further includes a tracking pen shaft and a connecting member, the tracking pen is connected to one end of the tracking pen shaft, and the connecting member is connected to the other end of the tracking pen shaft.

[0012] In some embodiments, the main optical axis of the rotating probe is arranged parallel to the tracking pen axis.

[0013] In some embodiments, the rotating probe is connected to the folding prism, the tracking pen is arranged on one side of the folding prism, and the rotating probe is arranged on the other side of the folding prism.

[0014] In some embodiments, the rotating probe includes a fiber optic collimator, an objective lens, and a reflecting prism. After entering the rotating probe, the detection light passes through the fiber optic collimator, the objective lens, and the reflecting prism in sequence, and then is reflected by the folding prism and enters the sample. The sample reflects and scatters the detection light and returns to the fiber optic coupler through the probe module.

[0015] In some embodiments, the rotating probe further includes a scanning component, and the detection light passes through the fiber optic collimator, is reflected by the scanning component, passes through the objective lens, and is incident on the sample after being reflected by the reflecting prism.

[0016] In some embodiments, the OCT imaging module further includes an image processing unit, which is connected to the detector and is used to process the light detected by the detector and reconstruct a three-dimensional contour.

[0017] The present invention has the following beneficial effects:

[0018] The present invention is provided with a tracking pen module and an OCT imaging module. The tracking pen module is used to scan the inner groove of the eyeglass frame to obtain the contour curve of the inner groove of the eyeglass frame. The main optical axis of the folding prism of the OCT imaging module is arranged in parallel with the tracking pen of the tracking pen module, so that the optical path of the detection light emitted by the probe module moves with the tracking pen module, and the trajectory traveled is the same as the contour curve of the inner groove of the eyeglass frame, thereby obtaining one dimension of the OCT three-dimensional imaging; and then the rotating probe is rotated around the main optical axis of the probe module, so that the detection light emitted by the rotating probe is rotated around the main optical axis, and the direction is folded after being reflected by the folding prism. It satisfies that the contour curve of the inner groove of the eyeglass frame is roughly orthogonal to obtain the other two dimensions of the OCT three-dimensional imaging. Combined with the one dimension along the contour curve, the OCT three-dimensional scanning of the inner groove of the eyeglass frame is realized to obtain the three-dimensional shape contour of the inner groove of the eyeglass frame, and then combined with the contour curve of the inner groove of the eyeglass frame and the three-dimensional shape contour of the inner groove of the eyeglass frame at multiple points, the three-dimensional shape contour of the entire eyeglass frame edge is obtained, and the edge cutting of the eyeglass lens can be more accurately guided, so that the eyeglass lens after edge cutting fits the inner groove of the eyeglass frame better, thereby improving the assembly quality and efficiency of the eyeglass lens, thereby saving the labor cost of lens trimming.

[0019] In some embodiments of the present invention, by arranging the tracking pen axis and the main optical axis of the rotating probe of the probe module in parallel, it is helpful to extend the tracking pen module and the probe module into the eyeglass frame to detect the three-dimensional shape contour of the eyeglass frame edge.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] Optical Coherence Tomography (OCT) is an emerging optical imaging technology. It has the advantages of high resolution, fast imaging speed, no radiation damage, moderate price, and compact structure. It is an important potential tool in the field of industrial and medical detection.

[0035] The embodiment of the present invention proposes a three-dimensional detection device for the contour of an eyeglass frame, which combines the OCT technology with an existing eyeglass frame edge detection device, and uses the tracking pen module of the eyeglass frame contour detection device to track and scan the eyeglass frame edge. At the same time, the detection light of the OCT imaging module performs a one-dimensional scan on the eyeglass frame edge to be measured, and receives the returned detection light signal, and then processes the received detection light signal, and combines the eyeglass frame edge trajectory obtained by the tracking pen scanning, so as to obtain the three-dimensional morphological contour data of the inner groove of the eyeglass frame, which is used to assist and guide the eyeglass lens edge cutting process, so that the eyeglass lens after edge cutting can better fit the inner groove of the eyeglass frame, thereby improving the efficiency and success rate of the eyeglass lens edge cutting process, improving the eyeglass lens edge cutting quality, avoiding many process problems such as lens assembly deformation due to inaccurate edge cutting, improving the eyeglass lens assembly quality and assembly efficiency, thereby saving labor costs and reducing the price of glasses.

[0036] The main structure of the device is as follows: it includes an OCT imaging module and a tracking pen module, the OCT imaging module includes an OCT light source, a fiber coupler, a probe module, a reference arm module, and a detector, the probe module includes a rotating probe and a folding prism, the rotating probe can rotate around the main optical axis of the probe module, the folding prism is used to fold light, the tracking pen module includes a tracking pen axis, the rotating probe, the folding prism, and the tracking pen module are connected in sequence, and the main optical axis of the folding prism is arranged parallel to the tracking pen axis;

[0037] The probe module moves with the tracking pen, and its moving trajectory is the same as the contour curve of the inner groove of the eyeglass frame, thereby obtaining one dimension of the OCT three-dimensional imaging; the rotating probe rotates around the main optical axis of the rotating probe, and the scanning light emitted from the rotating probe rotates around the main optical axis of the rotating probe. After being reflected by the folding prism, the scanning light is folded in direction, thereby obtaining the other two dimensions of the OCT three-dimensional imaging.

[0038] The detection light emitted by the OCT light source is split by the fiber coupler, and a part of it is transmitted to the reference arm module and then to the fiber coupler as the reference light, and the other part is transmitted to the probe module. The detection light emitted from the probe module moves with the tracking pen. The detection light returned from the probe module to the fiber coupler after being scattered by the sample interferes with the reference light returned from the reference arm module and is detected by the detector.

[0039] Example 1

[0040] The device of the embodiment of the present invention includes a tracking pen module and an OCT imaging module, and the structure diagram is as follows: Figure 2 As shown, not only the contour curve 901 of the inner groove of the eyeglass frame can be detected, but also the cross section 900 of the inner groove of the eyeglass frame can be obtained, thereby obtaining the three-dimensional shape contour data of the inner groove of the eyeglass frame.

[0041] Tracking pen module

[0042] The structure of the tracking pen module 30 in the embodiment of the present invention is as follows: Figure 3 As shown, the tracking pen module 30 includes a tracking pen 310, a tracking pen shaft 312, and a connecting member 324. The tracking pen module 30 has the tracking pen 310 connected to one end of the tracking pen shaft 312, and the connecting member 324 connected to the other end of the tracking pen shaft 312, and is connected to a multi-dimensional motion mechanism (not shown) of an existing eyeglass frame edge detection device via the connecting member 324. When mapping the contour curve 901 of the inner groove of the eyeglass frame, the tracking pen 310 can fit the inner groove of the eyeglass frame, and then driven by the tracking pen shaft 312 and the connecting member 324, it moves along the contour curve 901 of the inner groove of the eyeglass frame. The eyeglass frame edge detection device obtains the contour curve 901 of the inner groove of the eyeglass frame by detecting the moving trajectory of the tracking pen 310. Therefore, the existing eyeglass frame edge detection device can only obtain the contour curve 901 of the inner groove of the eyeglass frame of the glasses 90, and cannot obtain the shape of the cross section 900 of the inner groove of the eyeglass frame, so it cannot obtain the three-dimensional shape contour of the eyeglass frame edge.

[0043] OCT imaging module

[0044] The OCT imaging module includes an OCT light source 101, a fiber coupler 102, a probe module 20, a reference arm module 105, a detector 106, and an image processing unit, etc., wherein the image processing unit in this embodiment is a computer 107, which is connected to the detector 106 and is used to process the light detected by the detector 106 and reconstruct the three-dimensional contour.

[0045] Working principle of OCT imaging module: The light outputted by OCT light source 101 provides detection light to probe module 20 and reference arm module 105 through fiber coupler 102. A part of the light is transmitted to reference arm module 105 and then transmitted to fiber coupler 102 as reference light, wherein reference arm module 105 has a known length. Another part is transmitted to probe module 20, which provides detection light to the sample under test. The detection light returned from probe module 20 to fiber coupler 102 after being scattered by the sample interferes with the reference light returned by reference arm module 105 and is detected by detector 106. The light is then processed by computer 107 and finally displays the OCT image of the sample under test.

[0046] The probe module 20 includes a rotating probe 200 and a folding prism 401. The folding prism 401 can be a Porro prism, or other prisms or combined reflector structures, which can fold the detection light scanning plane. It also includes a driving device 211, which is connected to the probe module and is used to drive the rotating probe to rotate along the main optical axis of the probe module. The rotating probe 200 includes a fiber collimator 109, an objective lens 201, a reflecting prism 203, etc.

[0047] When OCT imaging is performed, the probe light is provided to the probe module 20 via the fiber coupler 102. The probe light enters the rotating probe 200, passes through the fiber collimator 109, the objective lens 201 to the reflecting prism 203, and then is reflected by the folding prism 401, and finally enters the sample. The sample reflects and scatters the probe light, and returns to the fiber coupler 102 via the probe module 20.

[0048] The rotating probe 200 can rotate around the main optical axis L2 of the rotating probe under the drive of the rotating probe driving device 211, so that the detection light emitted by the probe module 20 can be scanned, and a one-dimensional scan of the sample is performed to obtain a tomographic OCT image of the sample. Similarly, the rotating probe driving device 211 can also drive the reflecting prism 203 to rotate around the main optical axis L2 of the rotating probe, so that the detection light emitted by the probe module 20 can be scanned.

[0049] The folding prism 401 is connected to the tracking pen 310, and is specifically arranged next to the tracking pen 310 of the tracking pen module 30. The above-mentioned detection light is emitted through the folding prism 401, and the main optical axis L2' of the emitted folding prism is arranged parallel to the tracking pen 310. The purpose of this arrangement is that the tracking pen 310 scans the inner groove of the eyeglass frame to obtain the contour curve 901 of the inner groove of the eyeglass frame, and the contour curve 901 is obtained according to the displacement translation or rotation of the detection tracking pen 310. At this time, the main optical axis L2' of the folding prism of the detection light optical path emitted by the probe module 20 moves with the tracking pen 310, and the trajectory is the same as the contour curve 901 of the inner groove of the eyeglass frame. This moving trajectory realizes one dimension of OCT three-dimensional imaging. Then, the rotating probe 200 rotates around the main optical axis L2 of the rotating probe, and the scanning light emitted from the rotating probe 200 rotates around the main optical axis L2 of the rotating probe. Then, after being reflected by the folding prism 401, the scanning light is folded in direction to meet the requirement of being roughly orthogonal to the contour curve 901 of the inner groove of the eyeglass frame. This scanning mode realizes another two-dimensional OCT three-dimensional imaging, and finally, combined with the movement along the contour curve 901, the OCT three-dimensional scanning of the inner groove of the eyeglass frame is realized, and the OCT three-dimensional imaging of the inner groove of the eyeglass frame can be obtained.

[0050] The rotating probe 200 is connected to the folding prism 401 , specifically, is arranged next to the folding prism 401 , the tracking pen is arranged on one side of the folding prism, and the rotating probe is arranged on the other side of the folding prism, specifically, on the side away from the tracking pen 310 .

[0051] Figure 2 The relative positional relationship between the tracking pen module 30 and the probe module 20 is shown. The two are connected together through a mechanical component (not shown), so that the probe module 20 can follow the movement of the tracking pen module 30 . Figure 4 It is a side view showing the relative position relationship between the tracking pen module 30 and the probe module 20 .

[0052] The tracking pen axis 312 is arranged in parallel with the main optical axis L2 of the rotating probe of the probe module 20. This arrangement is conducive to allowing the tracking pen module 30 and the probe module 20 to be inserted into the eyeglass frame to detect the three-dimensional shape contour of the eyeglass frame edge. Figure 5 As shown:

[0053] The rotating probe 200 rotates around the main optical axis L2 of the rotating probe, so that the probe module 20 of the OCT imaging module can perform one-dimensional scanning. After passing through the folding prism 401, the scanning section, that is, the OCT imaging plane, is roughly orthogonal to the contour curve 901 of the inner groove of the eyeglass frame. The eyeglass frame contour detection device allows the probe module 20 of the OCT imaging module to move with the tracking pen module 30, so that the morphological data of the cross section 900 of the inner groove of the eyeglass frame at multiple points on the contour curve 901 of the inner groove of the eyeglass frame can be obtained. The computer 107 can reconstruct the three-dimensional morphological contour of the edge of the eyeglass frame through the contour curve 901 of the inner groove of the eyeglass frame and the morphological data of the cross section 900 of the inner groove of the eyeglass frame at multiple points. Based on the three-dimensional morphological contour data of the inner groove of the eyeglass frame, the lens edge cutting process can be more accurately assisted and guided, so that the assembly of the lens and the inner groove of the eyeglass frame is more fitted and matched, thereby improving the efficiency and success rate of the lens edge cutting process, improving the quality of lens edge cutting, and avoiding many process problems such as lens assembly deformation due to inaccurate edge cutting.

[0054] Example 2

[0055] Compared with Example 1, another probe module 2-20 solution is adopted in Example 2. Figure 6 As shown,

[0056] The probe module 2-20 includes a fiber optic collimator 2-109, a scanning component 2-209, an objective lens 2-201, a reflecting prism 2-203, etc.

[0057] When OCT imaging is performed, the probe light is provided to the probe module 2-20 via the fiber coupler 102. The probe light passes through the fiber collimator 2-109, is reflected by the scanning component 2-209, passes through the objective lens 2-201, is reflected by the reflecting prism 2-203, and finally enters the sample. The sample reflects and scatters the probe light and returns to the fiber coupler 102 via the probe module 2-20.

[0058] The scanning component 2-209, driven by the scanning driving device 2-211, realizes one-dimensional scanning of the sample, so that the OCT imaging module can obtain a tomographic OCT image of the sample.

[0059] Figure 6The relative positional relationship between the tracking pen module 30 and the probe module 2 - 20 is shown. The two are connected together by a mechanical component (not shown), so that the probe module 2 - 20 can follow the movement of the tracking pen module 30 .

[0060] The tracking pen axis 312 is arranged in parallel with the main optical axis 2-L2 of the probe module 2-20. This arrangement is conducive to allowing the tracking pen module 30 and the probe module 2-20 to be inserted into the eyeglass frame to detect the three-dimensional shape contour of the eyeglass frame edge.
