Description

Technical Field

[0001] The present invention relates to glass measurement, and in particular to a dispersive confocal sensor for glass measurement. Background Art

[0002] Confocal fiber technology has been developed for many years and is often used in ultra-precision detection applications. It can be mainly divided into laser confocal and dispersive confocal. Among them, laser confocal can provide high resolution, but its speed is slow. It often takes several hours to 1 day to complete 3D imaging in high-resolution mode, so it is not suitable for production line detection. Although dispersive confocal cannot achieve similar accuracy to confocal, it is faster in imaging speed and is more suitable for production line application detection, and is more suitable for glass measurement.

[0003] Therefore, a dispersive confocal sensor is generally used to measure glass. After the dispersive confocal sensor performs spectroscopic processing on the light source, it is irradiated onto the surface of the glass and the reflected light is collected. Since light of different wavelengths is reflected back by the glass at different angles, the thickness of the glass can be obtained by analyzing the reflected light with a spectrometer. However, most of the existing dispersive confocal sensors only focus on a small working distance and a small measurement range, such as the micron level. From the perspective of application and system, they are not suitable for glass measurement.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0031] Embodiment 1

[0032] The present invention provides a dispersive confocal sensor for glass measurement, such as Figure 1-7As shown, the dispersive confocal sensor includes a light source device, a chromatic aberration mirror group and a spectrometer. By redesigning the structure of the light source generated by the light source device, the chromatic aberration mirror group and the spectrometer, the measurement distance of the dispersive confocal sensor is increased, making it more suitable for measuring glass thickness.

[0033] Among them, the light source device is used to prepare a light source. Preferably, the light source provided by the present invention has stronger energy and higher surface reflectivity than the existing light source. For example, the intensity of the light source used in this embodiment is more than 30 times the intensity of the existing light source, and has a higher surface reflectivity.

[0034] The chromatic aberration mirror set is used to perform light splitting processing on the light source and irradiate the split light source onto the surface of the object to be measured. The present invention measures the thickness of the object to be measured by the relationship between the spectrum of the light source and the thickness of the object to be measured under the same material. That is, the correspondence between the simulated test light source and the thickness of different objects is pre-stored in the system, and then the light source is set and the light source is irradiated onto the surface of the object to obtain the reflected light, the spectrum of the reflected light is analyzed, and matched with the corresponding relationship stored in the system, so as to infer the thickness of the object to be measured.

[0035] Since the light source is generally white light, which includes multiple light beams of different wavelengths, when irradiating the surface of the object to be measured, the light source is first split by the chromatic aberration lens group to separate it into light beams of different wavelengths, which are then irradiated onto the surface of the object to be measured and the reflected light beams from the surface of the object to be measured are collected for spectral analysis, and finally the thickness of the object to be measured is obtained.

[0036] Preferably, the light source prepared by the light source device is input to the chromatic aberration mirror group through an optical fiber, and the chromatic aberration mirror group splits the light source and then irradiates the surface of the object to be measured.

[0037] like Figure 2-3 As shown, the chromatic aberration lens assembly includes a mounting seat, an adjustment seat 14 and a lens 13. The mounting seat includes a bottom plate 11 and a side plate 12 fixedly mounted on one side of the bottom plate 11. Preferably, the bottom plate 11 and the side plate 12 are arranged vertically.

[0038] The lens 13 is mounted on the side plate 12. The lens 13 is used to process the light source so that the light in the light source produces axial chromatic aberration so that the light source is converted into incident light, and then the incident light is irradiated onto the surface of the object to be measured. The axial chromatic aberration of the light determines the axial distance detected by the dispersive confocal sensor of this embodiment, which is also the inverse range of the test thickness.

[0039] Preferably, the object to be measured is arranged opposite to the lens 13 .

[0040] Preferably, a light source input end 15 is provided at one end of the adjustment seat 14. The light source input end 15 is connected to the light source device through an optical fiber for inputting the light source. Preferably, a first light path 17 is provided in the adjustment seat 14. The input end of the first light path 17 is connected to the light source input end 15, and the output end is arranged opposite to the lens 13, so that the light source enters the first light path 17 through the light source input end 15 and is transmitted to the lens 13, and then irradiates the surface of the object to be measured through the lens 13.

[0041] When the adjustment seat 14 is mounted on the base plate 11, the center line of the first optical path 17 in the adjustment seat 14 is on the same horizontal line as the center line of the lens 13. That is, the center line of the first optical path 17, the center line of the lens 13 and the object to be measured are all on the same horizontal line.

[0042] After the light source device is connected to the light source input end 15 through the optical fiber, the light source is prepared through the light source device. In this way, the light source enters the light source input end 15 through the optical fiber, and then enters the first optical path 17 and is output through the output end of the first optical path 17. By performing a spectroscopic process on the light source, that is, the light source generates an axial chromatic aberration to generate an incident light, and irradiates the incident light to the surface of the object to be measured. When the color confocal has an axial chromatic aberration condition, the spectral focusing characteristics will be like an encoder plate, and the reflected spectrum information can be obtained at different depths, so that the thickness of the glass can be measured according to the reflected information of each spectrum. The chromatic aberration mirror set provided by the present invention is equivalent to an encoder for encoding the light source. That is, the chromatic aberration mirror set is used to separate each light in the axial direction according to the direction of the optical axis when the light source passes through the lens 13, forming a series of axial focuses, which is equivalent to a spectrum encoder.

[0043] Preferably, the lens 13 in this embodiment is a cylindrical lens. The cylindrical lens is a projection rate gradient lens. The lens of the cylindrical lens is a small aperture lens. The diameter of the small aperture lens is 1 mm and the lens length is 10 mm.

[0044] Preferably, a mounting groove 16 is provided on the bottom plate 11 . The bottom of the adjustment seat 14 is arranged in the mounting groove 16 , so that the adjustment seat 14 is fixed on the bottom plate 11 .

[0045] The present invention uses white light (full-band light) generated by a light source device to pass through a chromatic aberration lens group and a lens 13 of the chromatic aberration lens group, so that the focal points of each wavelength are separated in the axial direction to form a series of axial focal points, just like an encoder made of a spectrum. In this way, when the glass to be tested has a height difference, the light source with axial chromatic aberration distribution reflected back by the chromatic aberration lens group is irradiated onto the glass to be tested, and different bands are measured due to the height difference of the glass to be tested, and then the height profile value of the glass to be tested can be obtained according to the spectrum analysis, that is, the thickness of the glass to be tested can be obtained.

[0046] When the incident light hits the surface of the object to be measured, since different wavelengths have different reflection angles for the same material, the incident light is reflected by the object to be measured and returns to the optical fiber through the lens 13 and the first optical path 17, and is finally transmitted to the spectrometer through the optical fiber.

[0047] Preferably, if Figure 4-7 As shown, the spectrum measuring instrument includes a control board 23, a module seat 2, an incident component 4 and a reflective component 3. The incident component 4 receives the reflected light sent by the chromatic aberration lens group through the optical fiber, so that the reflected light is reflected by the reflective component 3 to the reflective grating component 52 in the module seat 2, and then is received by the control board 23 arranged on the top of the module seat 2, and is transmitted to the external spectrum analyzer for spectrum analysis.

[0048] The module seat 2 includes a cavity composed of a first side wall, a second side wall, a third side wall, a fourth side wall, a bottom wall, a first top plate, a second top plate and a fifth side wall. In order to ensure that the reflected light is received, the present invention collects the reflected light reflected back from the object to be measured by a spectrometer.

[0049] The four sides of the bottom wall are provided with a first side wall, a second side wall, a third side wall and a fourth side wall in sequence, and the first side wall is symmetrically arranged with the second side wall, and the third side wall is symmetrically arranged with the fourth side wall; the first top plate is arranged above the third side wall and forms an acute angle with the third side wall, the second top plate is arranged above the fourth side wall and forms a 90-degree angle with the fourth side wall, one side of the fifth side wall forms a 90-degree angle with the second top plate, and the other side forms an acute angle with the first top plate, thereby forming a cavity of the module seat 2.

[0050] Preferably, the first top plate is an annular structure with a fourth opening in the middle, and the fourth opening corresponds to the cavity of the module base 2 .

[0051] A grating base 51 is installed at the bottom of the module base 2. The grating base 51 extends into the cavity of the module base 2 and passes through the bottom wall of the module base 2. A reflective grating component 52 is provided on the grating base 51, and the reflective grating component 52 is used to reflect the reflected light so as to transmit the reflected light to the control board 23 through the fourth opening of the first top plate.

[0052] Preferably, the incident component 4 includes a connector 41 and an adapter 42. One end of the connector 41 is connected to the reflected light sent by the chromatic aberration lens group through an optical fiber. The other end of the connector 41 is connected to the second optical path 44 in the adapter 42, and is used to transmit the reflected light to the cavity of the module seat 2.

[0053] Preferably, a first opening 43 is provided on the fifth side wall. The adapter 42 is fixed on the second top plate, and the center lines of the connector 41, the second optical path 44 in the adapter 42, and the first opening 43 are on the same horizontal line. When the adapter 42 is installed on the second top plate, the connector 41, the second optical path 44 in the adapter 42, and the first opening 43 are arranged opposite to each other. That is, when the connector 41 receives the reflected light through the optical fiber, the reflected light enters the second optical path 44 through the connector 41 for transmission and is incident into the cavity of the module seat 2 through the first opening 43.

[0054] Preferably, the first side wall is provided with a second opening 35. The reflective assembly 3 includes a reflector mounting assembly and a reflector 31. One end of the reflective mounting assembly is provided outside the cavity of the module seat 2, and the other end extends into the cavity of the module seat 2 through the second opening 35. The reflector 31 is mounted on one end of the reflector mounting assembly in the cavity of the module seat 2.

[0055] The reflector 31 is used to reflect the reflected light incident into the cavity of the module seat 2 and send it to the reflective grating component 52 in the module seat 2, and then transmit the reflected light to the control board 23 for reception after being reflected by the reflective grating component 52. When the reflector mounting component extends into the cavity of the module seat 2 through the second opening 35, the reflector 31 is arranged opposite to the first opening 43 to ensure that the center point of the reflector 31 and the center point of the first opening 43 are on the same horizontal line. In this way, the reflected light incident into the cavity of the module seat 2 through the first opening 43 is reflected by the reflector 31 to the reflective grating component 52 located in the cavity of the module seat 2. Figure 5 As shown, the curve part is the transmission path of the reflected light, that is, the reflected light passes through the incident component 4 to reach the reflector 31, and reaches the reflective grating component 52 under the reflection of the reflector 31, and then is reflected by the reflective grating component 52 and collected by the control board 23.

[0056] Preferably, the reflector mounting assembly includes a reflector mounting shaft 33 and a reflector adapter 32. One end of the reflector mounting shaft 33 is spirally mounted inside the reflector adapter 32. The reflector adapter 32 extends into the cavity of the module seat 2 through the second opening 35, and the reflector 31 is mounted on the reflector adapter 32. By rotating the reflector mounting shaft 33, the reflector adapter 32 is driven to rotate, that is, the reflector 31 is driven to rotate, so that the direction of the reflector 31 is adjusted, and the reflection angle of the reflected light passing through the reflector 31 is adjusted.

[0057] Preferably, a fixing knob 34 is provided at one end of the reflector mounting shaft 33 outside the cavity of the module base 2 , and the reflector mounting shaft 33 is driven to rotate by rotating the fixing knob 34 .

[0058] Preferably, a mounting plate 21 is provided on the first top plate. The control plate 23 is provided above the mounting plate 21. A third opening 24 is provided on the mounting plate 21, and the third opening 24 is arranged opposite to the fourth opening of the first top plate. Preferably, the aperture of the fourth opening is larger than the aperture of the third opening 24. In this way, the reflected light can pass through the fourth opening completely, and the reflected light will not be not collected by the control plate 29 due to the small aperture of the fourth opening, resulting in inaccurate calculation results. Preferably, the mounting plate 21 is fixedly mounted on the first top plate by screws. The mounting plate 21 is fixedly connected to the first top plate by screws.

[0059] Furthermore, a control panel mounting frame 22 is also mounted on the mounting plate 21. The control panel mounting frame 22 is fixedly connected to the mounting plate 21 by screws. The control panel 23 is mounted on the control panel mounting frame 22.

[0060] After the reflected light reflected by the reflector 31 is reflected again by the reflective grating assembly 52, it is collected by the control board 23 installed on the control board mounting frame 22 through the fourth opening and the third opening 24 in sequence, so that the control board 23 can collect the reflected light after the glass to be tested and send it to the remote spectrometer, so that the spectrometer can perform spectral analysis on the light reflected by the glass to obtain the thickness of the glass, thereby measuring the thickness of the glass. Since the wavelengths of the light after the spectrometry are different, the reflection angles are different after being reflected by the glass to be tested. Therefore, the spectrometer can perform spectral analysis based on the light of different wavelengths reflected back to obtain the thickness of the glass to be tested. The focus of the present invention is how to irradiate the light source onto the glass to be tested, and how to calculate the thickness of the glass based on the light reflected back by the glass to be tested is not the research focus of the present invention. The calculation process is a technology well known to those skilled in the art, and the present invention will not introduce it in detail.

[0061] The spectrometer provided by the present invention has a simple structure and is easy to operate. The user only needs to connect the connector 41 to the reflected light through the optical fiber, and then adjust the angle of the reflector 31 by turning the fixed knob 34, so that the reflected light can be transmitted to the reflective grating component 52 located at the bottom of the cavity of the module seat 2 through the reflection of the reflector 31, and after being reflected again by the reflective grating component 52, the reflected light is sequentially transmitted to the receiving plate 23 through the fourth opening and the third opening 24 for reception, thereby realizing the light reflected back from the object to be measured, which greatly reduces the difficulty of user operation.

[0062] The present invention irradiates the surface of the object to be measured after the light source is split by the lens 13 of the chromatic aberration mirror group, and then transmits the reflected light reflected by the object to be measured to the spectrometer through the chromatic aberration mirror group, so that the incident component 4 and the reflection component 3 in the spectrometer transmit the reflected light to the control board 23 for receiving, and finally the control board 23 sends the received light to the spectrometer to perform spectral analysis, and finally the thickness of the glass to be measured is obtained, thereby realizing the glass thickness measurement.

[0063] The present invention manufactures a light source with relatively high energy, separates the light through a chromatic aberration lens assembly, and then irradiates the light onto the glass to be measured through a spectrometer, thereby collecting the light reflected by the glass to be measured, thereby measuring the thickness of the glass to be measured. The chromatic aberration confocal sensor provided by the present invention can be applied to the measurement of glass with a thickness of 5 to 10 mm. It has a simple structure and is easy to operate, thus solving the problem that the confocal sensor in the prior art cannot measure the thickness of the glass.

[0064] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
