Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass thickness measurement technology, and in particular to a glass thickness measurement device. Background Technology
[0002] Accurately measuring glass thickness is crucial in the production, processing, and use of glass. Currently, common methods for measuring glass thickness include contact and non-contact methods. Contact measurements can damage the glass surface, affecting its quality and performance. Non-contact measurements primarily rely on two independent light sources (usually lasers or collimated LED light sources) fixed at symmetrical or known angles, projecting light onto the glass surface from different directions. An industrial camera or linear array sensor captures images of the light spots formed by reflection / refraction from the upper and lower surfaces of the glass. Image processing extracts the distance between the two light spots on the image plane, and the glass thickness is then calculated using trigonometric methods or optical path difference algorithms.
[0003] While this non-contact measurement avoids contact damage, the current hardware costs are high, requiring two independent light sources; the size is large, and the dual light sources occupy a lot of space, making it difficult to arrange the whole machine in narrow process sections or inside the machine; the assembly and adjustment are complicated, the two light sources must be strictly coplanar and the included angle must be stable, and temperature drift or mechanical vibration can easily cause measurement errors. Utility Model Content
[0004] In view of this, the present invention provides a glass thickness measuring device that can effectively and dynamically adjust the position of the light source, so that a single light source can emit light from different angles, which is then reflected by the glass and received by the detection unit to generate a light spot image. This avoids the problems of high hardware cost, large size and complicated assembly and adjustment of having two light sources in the same device.
[0005] Some embodiments of this application provide a glass thickness measuring device, including:
[0006] The box has a cavity inside and a light-transmitting opening on the top.
[0007] An integrating sphere unit is disposed within a receiving cavity, and the integrating sphere unit includes: a first rotating assembly, one end of which is connected to the housing;
[0008] An outer housing has a cavity inside and a light outlet on its surface. The outer housing is rotatably connected to the other end of the first rotating assembly so that the light outlet can be aligned with the light-transmitting port from different angles.
[0009] An integrating sphere includes a light inlet and a light outlet. The integrating sphere is disposed within the cavity, and the light outlet corresponds to the light exit. A light source emitter is disposed at the light inlet of the integrating sphere. The light emitted by the light source emitter is emitted from the light outlet and is used to illuminate the glass placed in the light-transmitting port.
[0010] The detection unit is disposed within the receiving cavity, and the detection unit includes: a second rotating assembly, one end of which is connected to the housing;
[0011] The detection component is rotatably connected to the other end of the second rotating component to receive light reflected from the surface of the glass and generate a light spot image, which is used to analyze the thickness of the glass.
[0012] In one possible implementation described above, a baffle plate is also included, which is disposed within the receiving cavity and between the integrating sphere unit and the detection unit, for isolating the integrating sphere unit and the detection unit.
[0013] In one possible implementation described above, the integrating sphere contains a cavity, and a baffle is provided inside the cavity to change the path of the light emitted by the light source within the cavity.
[0014] In one possible implementation described above, a beam control component is provided at the light outlet to change the shape of the light emitted by the light source.
[0015] In one possible implementation described above, a bandpass filter assembly is provided at the light-transmitting opening. The bandpass filter assembly includes a bandpass filter sheet, which is used to filter light reflected from the surface of the glass.
[0016] In one possible implementation described above, the housing is provided with a first limiting hole and a second limiting hole, and the glass thickness measuring device further includes:
[0017] The first actuating lever has one end connected to the outer housing and the other end extending out from the first limiting hole;
[0018] The second lever has one end connected to the detection component and the other end extending from the second limiting hole.
[0019] In one possible implementation described above, a first electric turntable is also included, with one end of the first electric turntable connected to the housing and the other end connected to the first rotating assembly.
[0020] In one possible implementation described above, a second electric turntable is also included, with one end of the second electric turntable connected to the housing and the other end connected to the second rotating assembly.
[0021] In one possible implementation described above, a first electric slide rail is also included. The first electric slide rail is disposed inside the housing and has a first slider, which is connected to the rotating assembly.
[0022] In one possible implementation described above, a second electric slide rail is also included. The second electric slide rail is disposed inside the housing and has a second slider, which is connected to the second rotating assembly.
[0023] In this embodiment of the invention, the integrating sphere unit and the detection unit are integrated into the same housing. The housing has a light-transmitting opening. Light emitted from the integrating sphere unit passes through this opening and illuminates the glass surface. The detection unit then receives the reflected light from the glass surface and generates a light spot image. A rotating assembly allows adjustment of the integrating sphere unit's position, thereby changing the incident angle between the emitted light and the glass. Using a combination of a lever and the rotating assembly, or a combination of an electric turntable and the rotating assembly, or an electric slide rail and the rotating assembly, the position of the integrating sphere unit can be dynamically adjusted. This allows a single integrating sphere unit to emit light from different angles, which is then reflected by the glass and received by the detection unit to generate a light spot image. This avoids the need for two integrating sphere units and two detection units in the same device, solving the problems of high hardware cost, large size, and complex assembly and adjustment.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0042] To facilitate understanding of the technical solution of the glass thickness measuring device in the embodiments of this application, the technical problem to be solved by the embodiments of this application will be explained first.
[0043] The working principle of the glass thickness measuring device will be explained first, followed by a combination of... Figure 1 This section explains the problems with the glass coating orientation recognition devices in some existing embodiments.
[0044] Common methods for measuring glass thickness are divided into contact and non-contact methods. Contact measurement may damage the glass surface, affecting its quality and performance; non-contact measurement mainly uses two independent light sources fixed at symmetrical or known angle positions to project light onto the glass surface from different directions. An industrial camera or linear array sensor then captures images of light spots formed by reflection / refraction on the upper and lower surfaces of the glass. Image processing is used to extract the distance between the two light spots on the image plane, and then the glass thickness is inverted based on trigonometric methods or optical path difference algorithms.
[0045] While this non-contact measurement method avoids contact damage, it has problems such as high hardware cost (requiring two independent light sources), large size (dual light sources occupy a large space, making it difficult to arrange the whole machine in narrow process sections or inside the machine), and complex assembly and adjustment (the two light sources must be strictly coplanar and have a stable angle, and temperature drift or mechanical vibration can easily cause measurement errors).
[0046] refer to Figure 1 , Figure 1 Schematic diagrams of glass thickness measuring devices in some embodiments are shown. For example... Figure 1 As shown, in order to achieve contact-based identification of glass thickness, the glass thickness measuring device includes: a first light source 1a, a second light source 1b, a data acquisition unit 2, and a packaging box 3.
[0047] In this process, a first light source 1a emits a first emitted ray X1 towards glass 4. This ray is reflected by the front of glass 4 to obtain a first reflected ray y1, and by the back of glass 4 to obtain a second reflected ray y2. The acquisition unit 2 receives the first reflected ray y1 and the second reflected ray y2 and generates a first light spot image. A second light source 1b emits a second emitted ray X2 towards glass 4. This ray is reflected by the front of glass 4 to obtain a third reflected ray y3, and by the back of glass 4 to obtain a fourth reflected ray y4. The acquisition unit 2 receives the third reflected ray y3 and the fourth reflected ray y4 and generates a second light spot image.
[0048] The processing unit (not shown) receives the first spot image and the second spot image transmitted by the acquisition unit 2, and calculates the glass thickness data based on the first spot image and the second spot image.
[0049] However, the above-mentioned glass thickness measuring device has the following problems:
[0050] (1) The hardware cost is high, requiring two independent light sources.
[0051] (2) The machine is large in size and requires a lot of space for dual light sources, making it difficult to arrange the whole machine in narrow process sections or inside the machine.
[0052] (3) The setup and adjustment are complicated. The two light sources must be strictly coplanar and the included angle must be stable. Temperature drift or mechanical vibration can easily cause measurement errors.
[0053] To address the issues of high hardware cost, large size, and complex assembly and adjustment of the glass thickness measuring device described above, embodiments of this application provide a glass thickness measuring device. This device utilizes an integrating sphere unit housed within a housing, which can rotate within the housing. This allows for dynamic adjustment of the light illumination angle of the light source emitter within the integrating sphere unit, thereby enabling multi-angle light source processing from a single integrating sphere unit. This avoids the problems of high hardware cost, large size, and complex assembly and adjustment associated with multiple integrating sphere units.
[0054] The glass thickness measuring device of this application embodiment will be described in detail below with reference to the accompanying drawings.
[0055] refer to Figure 2 , Figure 2 A schematic diagram of the glass thickness measuring device according to an embodiment of this application is shown.
[0056] like Figure 2 As shown, the glass thickness measuring device includes a housing 12, an integrating sphere unit 2A, and a detection unit 2B. The housing 12 has a receiving cavity 12A and a light-transmitting opening 5. The integrating sphere unit 2A and the detection unit 2B are disposed within the receiving cavity 12A.
[0057] The integrating sphere unit 2A may include a first rotating component 8, an outer housing 9, an integrating sphere (not shown), and a light source emitter (not shown). One end of the first rotating component 8 is connected to the housing 12, and the other end is rotatably connected to the outer housing 9. By rotating the first rotating component 8, the outer housing 9 is driven to rotate, so that the light outlet (not shown) on the outer housing 9 is aligned with the light transmission port 5 on the housing from different angles.
[0058] Both the light source emitter (not shown) and the integrating sphere (not shown) are housed inside the outer housing 9, and the light emitted by the light source emitter can be homogenized by the integrating sphere and then emitted from the light outlet on the outer housing 9.
[0059] The detection unit 2B may include a detection component 11 and a second rotation component 18. One end of the second rotation component 18 is connected to the housing 12, and the other end is rotatably connected to the detection component 11 so that the detection component 11 can rotate.
[0060] It should be noted that by rotating the second rotating component 18, the detection component 11 is driven to rotate, thereby enabling the detection component 11 to receive reflected light from the glass from different angles.
[0061] During measurement, the glass can be placed on the outside of the housing 12 at the light-transmitting port 5. The integrating sphere unit 2A emits light through the light-transmitting port 5 and illuminates the glass. After receiving the reflected light from the glass, the detection component 11 generates a light spot image and transmits the light spot image to the processing unit (not shown). The processing unit (not shown) processes the image to obtain the thickness data of the glass.
[0062] It should be noted that, compared with existing glass thickness measuring devices, the glass thickness measuring device provided in this application assembly assembles a light source emitter and an integrating sphere, making the light emitted by the light source emitter more uniform after being processed by the integrating sphere, thereby making the light spot image collected by the detection unit clearer. By providing a rotating component between the housing and the outer shell of the integrating sphere, the integrating sphere unit can rotate within the housing, thereby dynamically adjusting the light illumination angle of the light source emitter, thus solving the problems of high hardware cost, large size, and complex assembly and adjustment of existing glass thickness measuring devices.
[0063] like Figure 2 As shown, the glass thickness measuring device also includes: a circuit board 6, an adapter port 13, a data transmission port 14, a data cable 15, and a processing unit (not shown).
[0064] The adapter port 13 and data transmission port 14 are located on the housing 12. One end of the adapter port 13 is connected to a power supply (not shown) via a data cable 15, and the other end is connected to the circuit board 6 via the same data cable 15 to power the glass thickness measuring device. The circuit board 6 is connected to the integrating sphere unit 2A and the detection unit 2B via the data cable 15 for power supply and data transmission. The circuit board 6 receives the light spot image via the data cable 15 and transmits it to the processing unit (not shown) via the data transmission port 14. The processing unit (not shown) calculates the thickness of the glass. Additionally, the circuit board 6 may be equipped with a fan (not shown) for effective heat dissipation.
[0065] It is understood that the glass thickness measuring device in this application embodiment can be communicatively connected to the processing unit (not shown) to facilitate the processing of the light spot image. The two can be two independent parts. The processing unit (not shown) can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. In this application embodiment, the processing unit can be an electronic device with a display screen, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, or a wireless terminal in industrial control.
[0066] refer to Figure 3 , Figure 3 A schematic diagram showing the reflection of light from the integrating sphere unit in an embodiment of this application after passing through glass is shown. Figure 3 As shown, the third emitted ray X3 is an emitted ray emitted from the integrating sphere with an incident angle of 60 degrees between it and the glass. The fourth emitted ray X4 is an emitted ray emitted from the integrating sphere with an incident angle of 30 degrees between it and the glass. After reflection from the front of the glass, the third emitted ray X3 becomes the fifth reflected ray Y5, and after reflection from the back of the glass, it becomes the sixth reflected ray Y6. The fifth and sixth reflected rays Y5 and Y6 are collected by the detection unit to obtain a 60-degree spot image A1. The fourth emitted ray X4, after reflection from the front of the glass, becomes the seventh reflected ray Y7, and after reflection from the back of the glass, it becomes the eighth reflected ray Y8. The seventh and eighth reflected rays Y7 and Y8 are collected by the detection unit to obtain a 30-degree spot image A2. The processing unit can obtain the spot distance d1 based on the 60-degree spot image A1 and the spot distance d2 based on the 30-degree spot image A2. Substituting the spot distances d1 and d2 into the calculation formula, the thickness data of the glass is obtained.
[0067] In some embodiments, such as Figure 4 As shown, the integrating sphere unit may include an outer housing 9, an integrating sphere 20, and a first rotating assembly 8. The first rotating assembly 8 has connecting rods 26 at both ends, so that one end of the first rotating assembly 8 is connected to the housing and the other end is connected to the outer housing 9.
[0068] The outer housing 9 has a chamber 28 and a light outlet 21. An integrating sphere 20 is disposed within the chamber 28 and has a light inlet 27 and a light outlet 22. A light source emitter 25 is located at the light inlet 27, and the light outlet 22 corresponds to the light outlet 21, so that the light emitted by the light source emitter 25 can enter the integrating sphere 20 through the light inlet 27 for homogenization, exit through the light outlet 22, and pass through the light outlet 21.
[0069] The integrating sphere 20 has a cavity 24 inside, and a baffle 23 inside the cavity 24, which can prevent the light emitted by the light source emitter 25 from directly entering from the light inlet 27 and exiting from the light outlet 22.
[0070] It should be noted that by placing the integrating sphere 20 inside the outer housing 9 and connecting the first rotating component 8 to the outer housing 9, not only can the integrating sphere be rotated by turning the first rotating component 8, thereby changing the incident angle between the light emitted by the integrating sphere and the glass plate, but also by providing an outer housing 9 around the integrating sphere 20, the connection between the integrating sphere 20 and the first rotating component 8 can be made more secure.
[0071] In some embodiments, such as Figure 5 As shown, the first rotating assembly 8 may include a ball socket 801 and a ball head 802, and the ball socket 801 and the ball head 802 are respectively connected to a connecting rod 26. The ball socket 801 and the ball head 802 are movably connected. By moving the first actuating rod, the first rotating assembly 8 is rotated, thereby causing the integrating ball to rotate.
[0072] refer to Figure 6 , Figure 6 A schematic diagram of the structure of a glass thickness measuring device according to a second embodiment of this application is shown. Figure 6 The glass thickness measuring device shown is Figure 2 Compared to the glass thickness measuring device shown, the difference lies in the inclusion of a first actuating lever 7, a second actuating lever 19, a baffle plate 10, and a bandpass filter assembly (not shown), while the other components are the same (i.e., Figure 2 The components include an integrating sphere unit 2A, a detection unit 2B, a circuit board 6, a housing 12, an adapter port 13, and a data transmission port 14. The following details the components. Figure 6 The differences between the glass thickness measuring devices shown will be explained in detail, while the similarities will not be repeated.
[0073] The housing 12 has a first limiting hole 16 and a second limiting hole 17 on both sides. One end of the first actuating rod 7 is connected to the outer housing 9, and the other end protrudes from the first limiting hole 16. By actuating the first actuating rod 7, the first rotating assembly 8 is rotated, thereby changing the incident angle between the light emitted by the integrating sphere unit 2A and the glass plate. One end of the second actuating rod 19 is connected to the detection unit 2B, and the other end protrudes from the second limiting hole 17. When the incident angle between the light emitted by the integrating sphere unit 2A and the glass plate changes, the second rotating assembly 18 is rotated by actuating the second actuating rod 19, thereby changing the lens direction of the detection assembly 11 on the detection unit 2B, thus enabling it to better receive the reflected light from the glass. A bandpass filter assembly (not shown) is provided at the light-transmitting port 5 to filter the light reflected from the glass surface, thereby making the light spot image generated by the detection assembly 11 clearer.
[0074] It should be noted that the cooperation between the two ends of the length of the first limiting hole 16 and the toggle lever can make the incident angle between the light emitted by the integrating sphere unit 2A and the glass plate vary between 30 degrees and 60 degrees.
[0075] In some embodiments, a baffle 10 is provided in the receiving cavity 12A, and the baffle 10 is located between the integrating sphere unit 2A and the detection unit 2B to isolate the integrating sphere unit 2A and the detection unit 2B.
[0076] It should be noted that the baffle 10 can effectively prevent the light emitted by the integrating sphere unit 2A from being directly collected by the detection unit 2B, thus preventing the generated light spot image from being unclear.
[0077] In some embodiments, a beam control device (not shown) is provided at the light outlet (not shown) of the integrating sphere unit 2A. This beam control device (not shown) can be a linear aperture or a collimating lens. The size and range of the beam entering the glass plate can be limited by adjusting the opening shape and size of the linear aperture, preventing excessive light from entering and thus reducing the quality of the light spot image generated by the detection component 11. Furthermore, the collimating lens can focus the light emitted by the integrating sphere unit 2A to a single point, and the detection component 11 receives the reflected light from the glass plate, thereby forming a clearer light spot image.
[0078] In some embodiments, such as Figure 7 As shown, the bandpass filter assembly includes: a bracket 29, which is fixed on the housing 12 and corresponds to the light-transmitting port 5, and a bandpass filter 30 is fixed on the bracket 29.
[0079] It should be noted that fixing the bandpass filter 30 on the bracket 29 and setting the bracket 29 on the housing 12 relative to the light-transmitting port 5 can not only filter out light other than the light reflected from the glass surface, but also effectively avoid damage to the bandpass filter 30 when the glass thickness measuring device collides with other objects, thereby reducing the frequency of replacing the bandpass filter 30.
[0080] refer to Figure 8 , Figure 8 A schematic diagram of the glass thickness measuring device according to the third embodiment of this application is shown. Figure 8 The glass thickness measuring device shown is Figure 6 Compared to the glass thickness measuring device shown, the difference lies in the presence of a first electric turntable 31 and a second electric turntable 32 within the receiving cavity 12A, while the rest of the structure remains the same (i.e., Figure 2 The components include an integrating sphere unit 2A, a detection unit 2B, a circuit board 6, a housing 12, an adapter port 13, and a data transmission port 14. The following details the components. Figure 8 The differences between the glass thickness measuring devices shown will be explained in detail, while the similarities will not be repeated.
[0081] like Figure 8 As shown, one end of the first electric turntable 31 is connected to the housing 12, and the other end is connected to the first rotating assembly 8, so that the light outlet is aligned with the light transmission port. One end of the second electric turntable 32 is connected to the housing 12, and the other end is connected to the second rotating assembly 18, so that the detection assembly 11 receives light reflected from the glass plate at different angles.
[0082] It should be noted that when the integrating sphere unit emits light at one position, and the detection unit completes the acquisition of the reflected light from the glass plate and generates the first light spot image at the corresponding position, the processing unit generates a control signal to control the rotation of the first electric turntable 31, thereby driving the integrating sphere unit to rotate. The processing unit can also generate a control signal to control the rotation of the second electric turntable 32, thereby driving the detection unit to rotate, allowing the detection unit to better receive the reflected light from the glass plate. Figure 2 Compared to the glass thickness measuring device shown, this embodiment generates control signals through the processing unit to drive the first electric turntable 31 and the second electric turntable 32 to rotate. This effectively avoids the problem of measurement inaccuracy caused by human error by manually rotating the integrating sphere unit and the detection unit, thus achieving a high degree of automation.
[0083] refer to Figure 9 , Figure 9 A schematic diagram of the glass thickness measuring device according to the fourth embodiment of this application is shown. Figure 9 The glass thickness measuring device shown is Figure 6Compared to the glass thickness measuring device shown, the difference lies in the presence of a first electric slide rail 33 and a second electric slide rail 34 within the receiving cavity 12A, while the rest of the structure remains the same (i.e. Figure 2 The components include an integrating sphere unit 2A, a detection unit 2B, a circuit board 6, a housing 12, an adapter port 13, and a data transmission port 14. The following details the components. Figure 9 The differences between the glass thickness measuring devices shown will be explained in detail, while the similarities will not be repeated.
[0084] like Figure 9 As shown, the first electric slide rail 33 includes a first track 331 and a first slider 332. The first track 331 is connected to the housing 12, and the first slider 332 is located on the first track 331 and connected to the first rotating component 8. The processing unit (not shown) can generate a control signal to control the sliding of the first slider 332, thereby driving the integrating sphere unit to rotate, and thus changing the incident angle between the emitted light of the integrating sphere unit and the glass.
[0085] The second electric slide rail 34 includes a second track 341 and a second slider 342. The second track 341 is connected to the housing 12, and the second slider 342 is located on the second track 341 and connected to the second rotating assembly 18. The processing unit (not shown) can generate a control signal to control the second slider 342 to slide, thereby driving the detection unit to rotate, and thus aligning the lens of the detection assembly 11 with the light-transmitting port so as to receive the reflected light from the glass and generate a light spot image.
[0086] It should be noted that when the integrating sphere unit emits light at one position, and the detection unit completes the acquisition of the reflected light from the glass plate and generates the first light spot image at the corresponding position, the processing unit generates a control signal to control the movement of the first slider 332, thereby causing the integrating sphere unit to rotate. The processing unit can also generate a control signal to control the movement of the second slider 342, thereby causing the detection unit to rotate, allowing the detection unit to better receive the reflected light from the glass plate. Figure 6 Compared to the glass thickness measuring device shown, this embodiment generates control signals through the processing unit to drive the first slider 332 and the second slider 342 to move. This can effectively avoid the problem of measurement inaccuracy caused by human error by manually rotating the integrating sphere unit and the detection unit, thus achieving a high degree of automation.
