Description

Technical Field

[0001] This utility model belongs to the field of paper quality testing technology, and relates to a fully automatic whiteness meter and its spectral control mechanism. Background Technology

[0002] Whiteness meters, as important optical analytical instruments for measuring the whiteness and colorimetric properties of material surfaces, are widely used in papermaking, textiles, ceramics, plastics, and food processing. Their core principle involves filtering the light source spectrum using a specific wavelength filter, capturing the reflected light signal from the sample using a photodetector, and then calculating the whiteness parameters.

[0003] Traditional whiteness meters are typically equipped with multiple filters of different wavelengths to meet the needs of different industry standards or testing scenarios. Different measurement modes are switched by changing different filters. In existing technologies, the incident light wavelength is adjusted by fixing the filter or manually switching the filter. However, when there are a large number of samples to process or when frequent switching of measurement modes is required, it often leads to a waste of a lot of manpower and time, further affecting the detection speed and resulting in low detection efficiency. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a spectral control mechanism for a fully automatic whiteness meter.

[0005] Another objective of this invention is to provide a fully automatic whiteness meter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spectral control mechanism for a fully automatic whiteness meter includes a front switching plate and a rear switching plate disposed between a light source generator and an integrating sphere. The front switching plate is provided with an ultraviolet cutoff filter module, and the ultraviolet cutoff filter module is also provided with a light-transmitting hole. The rear switching plate is provided with a blue filter and a green filter. The front switching plate and the rear switching plate are connected to a switching mechanism, which drives the front switching plate and the rear switching plate to move and change the spectrum of the light source entering the integrating sphere.

[0008] The front and rear switching plates are driven independently by the switching mechanism. The rear switching plate can quickly move to the target position to switch between the blue and green filters to quickly switch the measurement mode. The front switching plate can quickly move to the target position to quickly switch between the ultraviolet cutoff mode and the full-spectrum transmission mode. The two work together to ensure high accuracy and high efficiency measurement of the whiteness meter in complex application scenarios.

[0009] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, the switching mechanism includes guide sliding units respectively disposed between the front switching plate and the rear switching plate and the machine body. The front switching plate and the rear switching plate are parallel to each other. The blue filter and the green filter are distributed along the length direction of the rear switching plate. The light-transmitting part and the light-transmitting hole of the ultraviolet cut-off filter module are distributed along the length direction of the front switching plate. The front switching plate and the rear switching plate are connected to a switching drive assembly that can drive the front switching plate and the rear switching plate to reciprocate along the length direction, respectively.

[0010] The switching drive assembly can independently drive the front and rear switching plates to reciprocate along the length direction. By controlling the movement length of the front and rear switching plates, the alignment of the light-transmitting part and light-transmitting hole with the blue and green filters can be arbitrarily combined to flexibly and quickly switch between different measurement modes. The guide sliding unit plays a role in guiding the movement of the front and rear switching plates, ensuring the movement accuracy of the front and rear switching plates and preventing displacement that would affect the measurement.

[0011] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, the switching drive component includes a concentric dual-axis motor. A first drive gear and a second drive gear are fixed on the outer and inner shafts of the concentric dual-axis motor, respectively. A first rack portion and a second rack portion are respectively provided on the front switching plate and the rear switching plate. The first drive gear and the second drive gear are meshed and connected with the second rack portion and the first rack portion, respectively.

[0012] The outer and inner shafts of the concentric dual-axis motor can drive the first and second drive gears to rotate, respectively, so as to independently drive the rear and front switching plates to move to the target position and quickly switch between different measurement modes.

[0013] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, the ultraviolet cut-off filter module includes an ultraviolet cut-off filter, and the front switching plate is provided with a mounting hole for mounting the ultraviolet cut-off filter, and a light-transmitting hole is formed between the ultraviolet cut-off filter and the mounting hole.

[0014] The mounting holes on the front switching plate are used to position and install the ultraviolet cut-off filter. The ultraviolet cut-off filter can block ultraviolet light in the light source to eliminate the interference of ultraviolet light on the detection results. The light-transmitting hole formed between the ultraviolet cut-off filter and the mounting hole allows the full spectrum of the light source to pass directly. By moving the front switching plate, the ultraviolet cut-off mode and the full spectrum transmission mode can be quickly switched, or the amount of ultraviolet light in the light source can be adjusted.

[0015] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, the front switching plate and / or the rear switching plate are also provided with an auxiliary elastic reset mechanism.

[0016] The auxiliary elastic reset mechanism can pull the front switching plate and / or the rear switching plate to the initial position under normal conditions, thus playing a role in auxiliary reset.

[0017] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, the auxiliary elastic reset mechanism includes a tension spring. The front switching plate and / or the rear switching plate are provided with a fixing screw that cooperates with one end of the tension spring at the end away from the switching mechanism, and the other end of the tension spring is fixed by a fixing seat.

[0018] The tension spring can pull the front switching plate and / or the rear switching plate to move to the initial position, thus assisting in the reset process.

[0019] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, the guide sliding unit includes horizontal slide rails respectively disposed on the opposite sides of the front switching plate and the rear switching plate, and the front switching plate and the rear switching plate are provided with horizontal sliders that slide in cooperation with the horizontal slide rails.

[0020] The horizontal slider slides in conjunction with the horizontal slide rail, guiding the movement of the front and rear switching plates to ensure movement accuracy.

[0021] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, a displacement sensing component is also provided between the front switching plate and the rear switching plate and the machine body.

[0022] The shift sensing component is used to detect and provide feedback on the positions of the front and rear switching plates to ensure the accuracy and reliability of filter and aperture switching, thereby improving measurement accuracy and stability.

[0023] In the spectral control mechanism of the aforementioned fully automatic whiteness meter, the displacement sensing component includes sensor plates respectively disposed on the upper ends of the front switching plate and the rear switching plate, and sensor receivers that cooperate with the corresponding sensor plates are respectively disposed on the opposite sides of the front switching plate and the rear switching plate. The sensor receivers are connected to the machine body through a mounting bracket.

[0024] The sensor chip and the sensor receiver work together to detect and provide feedback on the positions of the front and rear switching plates, ensuring the accuracy and reliability of the filter and aperture switching, thereby improving measurement accuracy and stability.

[0025] A fully automatic whiteness meter includes a body and an upper base plate disposed within the body. An integrating sphere is provided on the upper base plate, and a light inlet and a light outlet are respectively provided on the side and bottom of the integrating sphere. A light source generator is provided on the upper base plate outside the light inlet, and a receiving device is provided below the light outlet. A spectral control mechanism for the fully automatic whiteness meter is provided on the upper base plate between the light inlet and the light source generator.

[0026] The light source emitted by the light source generator passes sequentially through the ultraviolet cutoff filter module and the target filter to change the spectrum of the light source entering the integrating sphere.

[0027] Compared with existing technologies, the advantages of this invention are: 1. The switching mechanism adopts an independent drive strategy, which has high driving accuracy and can quickly drive the front and rear switching plates to the target position, so as to flexibly and quickly switch between different measurement modes. 2. It allows for the parallel stacking layout of the front and rear switching plates, which can effectively save space and make the overall structure more compact, solving the problem of optical path integration in compact equipment.

Detailed Implementation

[0035] like Figures 1-6As shown, a spectral control mechanism for a fully automatic whiteness meter includes a front switching plate 3 and a rear switching plate 4 disposed between a light source generator 1 and an integrating sphere 2. The front switching plate 3 is provided with an ultraviolet cut-off filter module 34, and the ultraviolet cut-off filter module 34 is also provided with a light-transmitting hole 35. The rear switching plate 4 is provided with a blue filter 5 and a green filter 6. The front switching plate 3 and the rear switching plate 4 are connected to a switching mechanism 7. The switching mechanism 7 drives the front switching plate 3 and the rear switching plate 4 to move and change the spectrum of the light source entering the integrating sphere 2.

[0036] In this invention, the light source generator 1 emits a light source. During use, the switching mechanism 7 operates independently, driving the switching plate 4 to move until the target blue filter 5 or green filter 6 is precisely positioned on the optical axis of the light source. Simultaneously, the switching mechanism 7 independently drives the switching plate 3 to move, causing the ultraviolet cut-off filter module 34 to cover the light source. The light source passes sequentially through the ultraviolet cut-off filter module 34 and the target filter to alter the spectrum of the light source entering the integrating sphere 2.

[0037] The ultraviolet cut-off filter module 34 can block ultraviolet light in the light source to eliminate the interference of ultraviolet light on the detection results, and the light-transmitting hole 35 provides a filterless channel, allowing the full spectrum of the light source to pass directly.

[0038] The front switching plate 3 and the rear switching plate 4 are driven independently by the switching mechanism 7. The rear switching plate 4 can quickly move to the target position to switch between the blue filter 5 and the green filter 6 to quickly switch the measurement mode. The front switching plate 3 can quickly move to the target position to quickly switch between the ultraviolet cutoff mode and the full-spectrum transmission mode. The two work together to ensure the whiteness meter can measure with high accuracy and high efficiency in complex application scenarios.

[0039] By combining the displacement of the front switching plate 3 and the rear switching plate 4, four spectral modes can be generated: the ultraviolet cut-off filter module 34 cuts off ultraviolet light in conjunction with the blue filter 5 for ISO whiteness measurement; the ultraviolet cut-off filter module 34 cuts off ultraviolet light in conjunction with the green filter 6 for CIE whiteness measurement; the light-transmitting aperture 35 allows the full spectrum of the light source to pass directly through in conjunction with the blue filter 5 for blue light measurement containing ultraviolet light; and the light-transmitting aperture 35 allows the full spectrum of the light source to pass directly through in conjunction with the green filter 6 for full-spectrum green light colorimetry measurement.

[0040] The switching mechanism 7 adopts an independent drive strategy, which has high drive precision and allows for the parallel stacking layout of the front switching board 3 and the rear switching board 4. This effectively saves space and makes the overall structure more compact, solving the problem of optical path integration in compact equipment.

[0041] The rear switching plate 4 is provided with a first mounting hole 40 and a second mounting hole 41 for positioning and installing the blue filter 5 and the green filter 6, respectively.

[0042] Specifically, combining Figures 2-4As shown, the switching mechanism 7 includes guide sliding units 9 respectively disposed between the front switching plate 3 and the rear switching plate 4 and the body 8. The front switching plate 3 and the rear switching plate 4 are parallel to each other. The blue filter 5 and the green filter 6 are distributed along the length direction of the rear switching plate 3. The light-transmitting part 38 and the light-transmitting hole 35 of the ultraviolet cut-off filter module 34 are distributed along the length direction of the front switching plate 3. The front switching plate 3 and the rear switching plate 4 are connected to a switching drive assembly 10 that can drive the front switching plate 3 and the rear switching plate 4 to reciprocate along the length direction respectively.

[0043] The switching drive assembly 10 can independently drive the front switching plate 3 and the rear switching plate 4 to reciprocate along the length direction. By controlling the movement length of the front switching plate 3 and the rear switching plate 4, the alignment of the light-transmitting part 38 and the light-transmitting hole 35 with the blue filter 5 and the green filter 6 can be arbitrarily combined to flexibly and quickly switch between different measurement modes. The guide sliding unit 9 plays a role in guiding the movement of the front switching plate 3 and the rear switching plate 4, which can ensure the movement accuracy of the front switching plate 3 and the rear switching plate 4 and prevent displacement that would affect the measurement.

[0044] Specifically, combining Figures 2-6 As shown, the switching drive assembly 10 includes a concentric dual-axis motor 11. A first drive gear 14 and a second drive gear 15 are fixed on the outer shaft 12 and inner shaft 13 of the concentric dual-axis motor 11, respectively. A first rack portion 16 and a second rack portion 17 are respectively provided on the front switching plate 3 and the rear switching plate 4. The first drive gear 14 and the second drive gear 15 are meshed and connected with the second rack portion 17 and the first rack portion 16, respectively.

[0045] The concentric dual-axis motor 11 is located on one side of the light source generator 1.

[0046] The outer shaft 12 and inner shaft 13 of the concentric dual-axis motor 11 can drive the first drive gear 14 and the second drive gear 15 to rotate, so as to independently drive the rear switching plate 4 and the front switching plate 3 to move to the target position for rapid switching of different measurement modes.

[0047] Specifically, combining Figure 5 As shown, the ultraviolet cut-off filter module 34 includes an ultraviolet cut-off filter 36. The front switching plate 3 is provided with a mounting hole 37 for mounting the ultraviolet cut-off filter 36, and a light-transmitting hole 35 is formed between the ultraviolet cut-off filter 36 and the mounting hole 37.

[0048] The mounting hole 37 on the front switching plate 3 is used to position and install the ultraviolet cut-off filter 36. The ultraviolet cut-off filter 36 can block ultraviolet light in the light source to eliminate the interference of ultraviolet light on the detection results. The light-transmitting hole 35 formed between the ultraviolet cut-off filter 36 and the mounting hole 37 allows the full spectrum of the light source to pass directly.

[0049] The ultraviolet cutoff mode and full-spectrum transmission mode can be quickly switched by moving the front switching plate 3, or the amount of ultraviolet light in the light source can be adjusted.

[0050] Specifically, combining Figures 1-4 As shown, the front switching plate 3 and / or the rear switching plate 4 are also provided with an auxiliary elastic reset mechanism 19. The auxiliary elastic reset mechanism 19 includes a tension spring 20. The front switching plate 3 and / or the rear switching plate 4 away from the switching mechanism 7 is provided with a fixing screw 21 that cooperates with one end of the tension spring 20. The other end of the tension spring 20 is fixed by a fixing seat 22.

[0051] In this embodiment, the front switching plate 3 and the rear switching plate 4 are provided with an auxiliary elastic reset mechanism 19.

[0052] The tension spring 20 can pull the front switching plate 3 and the rear switching plate 4 to the initial position, which can eliminate the gear tooth transmission backlash and play an auxiliary reset role.

[0053] Specifically, combining Figure 3 and Figure 4 As shown, the guide sliding unit 9 includes horizontal slide rails 23 respectively disposed on the opposite sides of the front switching plate 3 and the rear switching plate 4, and horizontal sliders 24 disposed on the front switching plate 3 and the rear switching plate 4 that slide in cooperation with the horizontal slide rails 23.

[0054] The horizontal slider 24 slides in conjunction with the horizontal slide rail 23, which serves as a guide for the movement of the front switching plate 3 and the rear switching plate 4 to ensure movement accuracy.

[0055] The horizontal slide rails 23 are respectively set on the opposite sides of the front switching plate 3 and the rear switching plate 4 and are connected to the body 8. The horizontal slider 24 is provided with a sliding groove 39 that slides with the horizontal slide rail 23. The horizontal slide rail 23 is set on one side of the switching plate to reduce the height of the switching plate, which can effectively save space and make the overall structure more compact.

[0056] Specifically, combining Figure 2 and Figure 3 As shown, a displacement sensing assembly 25 is also provided between the front switching plate 3 and the rear switching plate 4 and the body 8. The displacement sensing assembly 25 includes sensor pieces 26 respectively disposed on the upper ends of the front switching plate 3 and the rear switching plate 4. Sensor receivers 27 that cooperate with the corresponding sensor pieces 26 are respectively disposed on the opposite sides of the front switching plate 3 and the rear switching plate 4. The sensor receivers 27 are connected to the body 8 through the mounting bracket 28.

[0057] The sensor plates 26 on the front switching plate 3 and the rear switching plate 4 move with the front switching plate 3 and the rear switching plate 4. The sensor plates 26 cooperate with the sensor receiver 27 to detect and provide feedback on the position of the front switching plate 3 and the rear switching plate 4, so as to ensure the accuracy and reliability of the switching of the filter and the aperture 6, thereby improving the measurement accuracy and stability.

[0058] like Figures 1-6 As shown, a fully automatic whiteness meter includes a body 8 and an upper base plate 29 disposed inside the body 8. An integrating sphere 2 is provided on the upper base plate 29. A light inlet 30 and a light outlet are respectively provided on the side and bottom of the integrating sphere 2.
