Description

Technical Field

[0001] The utility model relates to the technical field of phosphorescent material detection, in particular to a rapid detection device for phosphorescent materials. Background Art

[0002] Phosphorescent materials are widely used in photocatalysis, chemical analysis, bio-imaging, organic electroluminescence, solar cells, etc., and have become one of the current research hotspots. When phosphorescent materials are excited by irradiation, the electrons will transition from the ground state to the high-energy state, and when they transition from the high-energy state back to the ground state, they will radiate photons outward, which is called phosphorescence. Phosphorescent materials are materials with temperature-sensitive properties, and the phosphorescence lifetime of phosphorescent materials is related to temperature.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1-2 As shown, a rapid detection device for phosphorescent materials comprises a phosphorescent collection mechanism 1, wherein the phosphorescent collection mechanism 1 is communicatively connected to a spectrometer 2;

[0038] A constant temperature mechanism 3, a light shield 4 is mounted on the constant temperature mechanism 3, the phosphorescence collection mechanism 1 is arranged in the light shield 4, and an excitation light source 9 is also arranged in the light shield 4;

[0039] A heat conducting mechanism 5, wherein the heat conducting mechanism 5 is arranged on the constant temperature mechanism 3, and the heat conducting mechanism 5 is arranged corresponding to the light shield 4;

[0040] A heat-conducting substrate 6 is detachably connected to the heat-conducting mechanism 5 , and the heat-conducting substrate 6 is used for coating phosphorescent material.

[0041] When the phosphorescent material is tested, the constant temperature mechanism 3 is turned on and the test temperature is set. After the phosphorescent material is coated on the heat-conducting substrate 6, the heat-conducting substrate 6 is connected to the heat-conducting mechanism 5. The heating temperature of the constant temperature mechanism 3 is heat-conducted to the heat-conducting substrate 6 through the heat-conducting mechanism 5. The heat-conducting substrate 6 then conducts heat to the phosphorescent material, so that the phosphorescent material is at the set temperature, thereby regulating the phosphorescence life of the phosphorescent material; then the phosphorescent material is excited by the excitation light source 9, so that the phosphorescent material radiates phosphorescence, and the phosphorescence signal is collected by the phosphorescence collection mechanism 1. The phosphorescence signal collected by the phosphorescence collection mechanism 1 is then converted into spectral data by the spectrometer 2, and the light shield 4 can prevent external The influence of light radiation on the detection results. After the detection is completed, the heat-conducting substrate 6 is removed from the heat-conducting mechanism 5, and the detection temperature is set by the constant temperature mechanism 3, and then another heat-conducting mechanism 5 is replaced to coat the phosphorescent material for detection, so as to achieve rapid detection of the phosphorescent material; in this technical scheme, the operating temperature of the phosphorescent material is simulated and adjusted by heat conduction, so that the phosphorescence life of the phosphorescent material can be regulated, and the temperature regulation of the phosphorescent material detection is realized. In addition, the method of coating the phosphorescent material on the heat-conducting substrate 6 for detection can achieve rapid detection of the phosphorescent material, which has the beneficial effects of ensuring detection accuracy, improving detection efficiency, and improving reliability.

[0042] As a preferred embodiment, the phosphorescence collection mechanism 1 comprises:

[0043] A charge coupled device 11, wherein the charge coupled device 11 is disposed in the light shield 4, and the charge coupled device 11 is communicatively connected with the spectrometer 2;

[0044] The optical filter 12 is disposed in the light shield 4 and is disposed corresponding to the charge coupled device 11 . The optical filter 12 is used to filter out the excitation light.

[0045] During the excitation process of the excitation light source 9, the internal electrons of the phosphorescent material will transition to the excitation energy level, and then transition back to the ground state in the form of spontaneous radiation, releasing photons and generating phosphorescent emission, thereby generating phosphorescent radiation; the filter 12 is used to filter out at least part of the non-phosphorescent radiation, so that the phosphorescent radiation after passing through the filter 12 accounts for a higher proportion and the detection is more accurate. The excitation light source 9 usually has a narrower wavelength (such as an ultraviolet excitation light source), while the phosphorescent radiation has a wider wavelength, so the excitation light can be filtered out by the filter 12, so that the phosphorescent signal is collected by the phosphorescent collection mechanism 1, and then the spectrometer 2 converts the phosphorescent signal into spectral data, thereby ensuring the accuracy of the detection result.

[0046] As a preferred embodiment, the constant temperature mechanism 3 comprises:

[0047] A constant temperature heating platform 31, on which the heat conducting mechanism 5 is arranged;

[0048] The heat-insulating seat 32 is disposed around the constant temperature heating platform 31 , and the light shield 4 is mounted on the heat-insulating seat 32 .

[0049] Direct contact between the light shielding hood 4 and the components inside the light shielding hood 4 and the constant temperature heating platform 31 may cause malfunction or damage, so a heat insulating seat 32 is arranged around the constant temperature heating platform 31, and the light shielding hood 4 is mounted on the heat insulating seat 32. The heat insulating seat 32 prevents the constant temperature heating platform 31 from conducting heat to the light shielding hood 4 and the components inside the light shielding hood 4, thereby ensuring the service life. In addition, the heat insulating seat 32 can prevent direct contact between the staff and the constant temperature heating platform 31, thereby avoiding burns and improving safety.

[0050] As a preferred embodiment, Figure 3 As shown, the heat-conducting mechanism 5 includes a heat-conducting frame 51 , which is disposed on the constant temperature mechanism 3 , and the heat-conducting substrate 6 is detachably connected in the heat-conducting frame 51 .

[0051] The thermally conductive frame 51 is set on the constant temperature heating platform 31, and the thermally conductive frame 51 is heated by the constant temperature heating platform 31, and then the thermally conductive frame 51 conducts heat to the thermally conductive substrate 6. At the same time, the thermally conductive substrate 6 is detachably connected to the thermally conductive frame 51, and the thermally conductive substrate 6 and the thermally conductive frame 51 can be quickly disassembled or installed, thereby improving the detection efficiency.

[0052] Furthermore, a heat insulating frame 52 is also provided on the heat conducting frame 51 , and the heat insulating frame 52 is sealed and connected to the bottom end of the light shield 4 .

[0053] There is a gap between the thermal conductive frame 51 and the light shield 4. In order to prevent external light from affecting the detection accuracy of the phosphorescent material, a thermal insulation frame 52 is set on the thermal conductive frame 51. The thermal insulation frame 52 can seal the gap between the thermal conductive frame 51 and the light shield 4. At the same time, the thermal insulation frame 52 can prevent heat conduction between the thermal conductive frame 51 and the light shield 4.

[0054] Further, such as Figure 4 As shown, the heat-conducting substrate 6 is detachably connected to the heat-conducting frame 51 in the following manner:

[0055] Slide grooves 53 are provided on both sides of the heat-conducting frame 51 . A notch is also provided on the heat-conducting frame 51 . The notch is connected to the slide groove 53 . Heat-conducting bars 61 are integrally provided on both sides of the heat-conducting substrate 6 . The heat-conducting bars 61 are slidably connected in the slide groove 53 .

[0056] The heat-conducting frame 51 is set on the constant temperature heating platform 31, and the heat-conducting frame 51 is heated by the constant temperature heating platform 31, and the heat-conducting substrate 6 is slidably connected in the heat-conducting frame 51 through the slide grooves 53 opened on both sides of the heat-conducting frame 51, so that there are multiple contact surfaces between the heat-conducting substrate 6 and the heat-conducting frame 51, thereby ensuring the heat-conducting efficiency of the heat-conducting substrate 6, and the heat-conducting substrate 6 and the heat-conducting frame 51 can be quickly disassembled or installed; in order to further improve the heat-conducting efficiency of the heat-conducting substrate 6 and shorten the detection time, heat-conducting strips 61 are respectively provided on both sides of the heat-conducting substrate 6, and the contact area between the heat-conducting substrate 6 and the heat-conducting frame 51 is increased by the heat-conducting strips 61, thereby improving the heat conduction efficiency.

[0057] Furthermore, a heat insulating strip 62 is provided on the heat conductive substrate 6, and the heat insulating strip 62 is engaged in the slot, and a heat insulating handle 63 is also provided on the heat insulating strip 62. The heat insulating strip 62 is engaged in the slot, so that the detection accuracy is affected by external light entering the light shield 4 through the gap between the heat conductive substrate 6 and the slot; and the heat insulating handle 63 facilitates the staff to disassemble or install the heat conductive substrate 6.

[0058] As a preferred embodiment, a high-speed camera 9 is also provided in the light shield 4, and the high-speed camera 9 is provided corresponding to the thermal conductive substrate 6, and the high-speed camera 9 is also communicatively connected to a control module 7, and the control module 7 is used to control the high-speed camera 9 to shoot.

[0059] Furthermore, a photosensitive device is also disposed in the light shield 4 , and the photosensitive device includes a photodiode 72 , and the photosensitive diode 72 is communicatively connected with the control module 7 .

[0060] When the phosphorescence radiated by the phosphorescent material is composed of multiple types of phosphorescence, it is necessary to compare the intensities of the multiple types of phosphorescence at different times. The control module 7 can control the high-speed camera 9 to shoot the multiple types of phosphorescence at different times. The high-speed camera 9 shoots in color to facilitate comparison by the staff. The radiation intensity of the phosphorescence can be monitored by the photodiode 72, and multiple thresholds can be set in the control module 7. When the photodiode 72 monitors the phosphorescence radiation and the radiation decays to the threshold, the control module 7 controls the high-speed camera 9 to shoot to prevent the staff from missing the best shooting time.

[0061] As a preferred embodiment, Figure 5 As shown, the shading cover 4 is also connected with a periscope 8. The periscope 8 connected through the shading cover 4 facilitates the inspection of the shading cover 4 during the detection of phosphorescent materials, and can prevent external light from entering the shading cover 4 to affect the detection accuracy.
