Description

Technical Field

[0001] This invention relates to the field of temperature measuring equipment technology, and more specifically, to an optical component temperature measuring system and method. Background Technology

[0002] Traditional contact temperature measuring tools (thermocouples) require attaching the thermocouple to the surface of the light guide when measuring the temperature of the light guide end face. However, the thermocouple material and the thermally conductive adhesive used to attach the thermocouple are opaque. When the LED is lit, some of the light energy that should enter the light guide is absorbed by the opaque thermocouple and converted into heat energy. This will cause the thermocouple to measure a higher temperature at the light guide end face. The thermal effect generated by the thermocouple absorbing light energy radiation may even cause the light guide to ablate. Summary of the Invention

[0061] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0062] Example 1:

[0063] like Figures 1-12 As shown, this embodiment provides an optical component temperature measurement system, including: a temperature tester 4, an optical component fixing device, and a position adjustment device 7. The optical component fixing device is used to fix the optical component 5 at the detection position, which is set on the first side of the position adjustment device 7. The temperature tester 4 is located on the second side of the position adjustment device 7 and is set corresponding to the detection position. The temperature tester 4 is used to measure the temperature of the surface 501 of the optical component 5 to be measured. Before the temperature measurement begins, the position adjustment device 7 is used to move the light source and the heat sink 6 to a position where the light source can be aligned with the surface 501 of the optical component 5 to be measured. During the temperature measurement, the position adjustment device 7 is used to move the light source and the heat sink 6 to an area that does not obstruct the detection signal of the temperature tester 4.

[0064] In this embodiment, the optical component 5 is a light guide, and the surface to be tested 501 is the light guide end face.

[0065] In this embodiment, the position adjustment device 7 is disposed between the detection position and the temperature tester 4, and the position adjustment device 7 is provided with a through hole 301 that allows the detection signal of the temperature tester 4 to pass through.

[0066] The optical component fixing device includes a fixing base 2, a fixing assembly, and a locking claw. The fixing base 2 is mounted on the base 1, one end of the fixing assembly is mounted on the fixing base 2, and the locking claw is located at the end of the fixing assembly away from the fixing base 2. The locking claw is used to lock and fix the optical component 5. There are one or more fixing assemblies, and the number of locking claws and fixing assemblies is the same. Before the test begins, the locking claw fixes the optical component 5 in the detection position.

[0067] In this embodiment, two fixing components are provided, namely a first fixing component 201 and a second fixing component 202; two locking claws are provided, namely a first locking claw 203 and a second locking claw 204. One end of the first fixing component 201 and one end of the second fixing component 202 are both disposed on the fixing base 2. The first locking claw 203 is disposed at the end of the first fixing component 201 away from the fixing base 2, and the second locking claw 204 is disposed at the end of the second fixing component 202 away from the fixing base 2. The first locking claw 203 and the second locking claw 204 are used to lock and fix the optical component 5. The first locking claw 203 and the second locking claw 204 are respectively locked at different positions of the optical component 5 to complete the clamping and fixing of the optical component 5.

[0068] The fixing assembly includes at least one adjusting shaft. One end of the adjusting shaft is connected to the fixing base 2, and the locking claw is located at the other end of the adjusting shaft. After clamping and fixing the optical component 5, the position of the test surface 501 of the optical component 5 is further adjusted by the adjusting shaft. The fixing assembly includes three adjusting shafts, namely a first adjusting shaft, a second adjusting shaft, and a third adjusting shaft. One end of the first adjusting shaft is rotatably mounted on the fixing base 2, one end of the second adjusting shaft is rotatably mounted at the other end of the first adjusting shaft, and one end of the third adjusting shaft is rotatably mounted at the other end of the second adjusting shaft. The locking claw is located at the other end of the third adjusting shaft. By adjusting each adjusting shaft, the test surface 501 of the optical component 5 is restricted above the through hole 301.

[0069] The position adjustment device 7 includes an adjustment base 3, an adjustment plate 9, and an adjustment frame 10. The adjustment base 3 is disposed between the detection position and the temperature tester 4. The adjustment plate 9 is slidably disposed on the adjustment base 3 along a first direction, and the adjustment frame 10 is slidably disposed on the adjustment plate 9 along a second direction. The adjustment base 3 is provided with a through hole 301 that allows the detection signal of the temperature tester 4 to pass through. The adjustment plate 9 is slidably disposed on the adjustment base 3 via a first adjustment slider 703 and a first adjustment slide rail 701, and the adjustment frame 10 is slidably disposed on the adjustment plate 9 via a second adjustment slider 704 and a second adjustment slide rail 702.

[0070] A light guide fixing device is used to fix and position the optical component, ensuring the test surface of the optical component is in a preset position before temperature measurement begins. A temperature tester 4 is used to emit a detection signal. After position adjustment, the detection signal emitter of the temperature tester is aligned with the test surface of the optical component, allowing the detection signal to be directly applied to the surface for temperature measurement. Before temperature measurement begins, a position adjustment device 7 moves the light source and heat sink 6 until the light source is aligned with the test surface of the optical component. After temperature measurement, the position adjustment device 7 moves the light source and heat sink 6 out of the area between the optical component 5 and the temperature tester 4, ensuring the detection signal from the temperature tester is applied directly to the test surface of the optical component.

[0071] The light source and heat sink are mounted on the adjustment frame 10. The positions of the light source and heat sink can be adjusted by sliding the adjustment frame 10 relative to the second adjustment slide rail 702 and the adjustment plate 9 relative to the first adjustment slide rail 701. Before the temperature measurement begins, the light source is aligned with the surface 501 to be measured of the optical component 5 and continuously lit for a preset time. Then, the adjustment frame is quickly moved away so that the detection signal of the temperature tester 4 can pass through the through hole 301 and hit the light-incident end face 501, allowing for direct measurement of the temperature of the light-incident end face 501. This provides a more accurate measurement of the end face temperature of the light-incident end face 501.

[0072] The optical component temperature measurement system of this embodiment also includes a height adjustment device 8, which is mounted on the base 1. The temperature tester 4 is mounted on the height adjustment device 8, and the height adjustment device 8 is used to adjust the height of the temperature tester 4.

[0073] This embodiment also provides a method for measuring the temperature of an optical component, based on the above-described optical component temperature measurement system, including the following steps:

[0074] Step 1: Fix the optical component 5 in the preset position using the optical component fixing device, and adjust the height of the temperature tester 4 using the height adjustment device 8 so that the detection signal of the temperature tester 4 can pass through the adjustment seat 3 of the position adjustment device 7, and make the test head 401 of the temperature tester 4 aligned with the test surface 501 of the optical component 5.

[0075] Step 2: Move the light source and heat sink 6 so that the light source is aligned with the test surface 501 of the optical component 5;

[0076] Step 3: Turn on the light source and let it stand for a preset time;

[0077] Step 4: Quickly move the light source and heat sink 6 away using the position adjustment device 7, and obtain the temperature of the test surface 501 of the optical component 5 using the temperature tester 4.

[0078] The optical component temperature measurement method of this embodiment further includes step 5, which specifically involves: adjusting the distance between the light source and the test surface 501 of the optical component 5, and repeating steps 1 to 4 to measure the temperature of the test surface 501 of the optical component 5 at different illumination distances, and taking the average value of multiple measurements as the temperature of the test surface 501 of the optical component 5.

[0079] The optical component temperature measurement system and method provided in this embodiment are also applicable to temperature measurement of other optical components besides light guides.

[0080] Example 2:

[0081] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0083] An optical component fixing device is used to fix the light guide in a designated position. After fixing, the light-incident surface of the light guide will be aligned with the test head of the temperature tester.

[0084] Position adjustment device 7, light source and heat sink 6 are mounted on position adjustment device 7, such as Figure 5 As shown, it can be used to adjust the position of the light source and heat sink 6 relative to the temperature tester 4 along the X-axis and Y-axis directions;

[0085] Adjustment seat 3, position adjustment device 7 is disposed on adjustment seat 3, and adjustment seat 3 is provided with through hole 301 for the detection signal of test head to pass through;

[0086] The position adjustment device 7 includes a first position adjustment device (a second adjustment slider 704 and a second adjustment slide rail 702) and a second position adjustment device (a first adjustment slider 703 and a first adjustment slide rail 701), as follows: Figure 5 As shown, the first position adjustment device is used to adjust the position of the light source and heat sink 6 relative to the temperature tester 4 along the X-axis, and the second position adjustment device is used to adjust the position of the light source and heat sink 6 relative to the temperature tester 4 along the Y-axis.

[0087] Furthermore, the first position adjustment device and the second position adjustment device are sliding rail structures;

[0088] Furthermore, the first position adjustment device and the second position adjustment device can be automatically controlled by the controller to accurately ensure the time for the light source to illuminate the light-introducing end face;

[0089] Furthermore, the optical component temperature measurement system also includes an adjustment base 3 for fixing the temperature tester 4 and the second position adjustment device;

[0090] Furthermore, the adjustment seat 3 is also provided with a through hole 301, and the detection signal emitted by the test head 401 of the temperature tester 4 can pass through the through hole 301 to reach the test surface 501 of the optical component 5 for temperature measurement.

[0091] Furthermore, the temperature tester 4 is equipped with a tester height adjustment device 8, such as... Figure 5 As shown, the Z-axis distance between the test head 401 and the test surface 501 of the optical component 5 is adjusted.

[0092] Furthermore, the optical component fixing device has an adjustment shaft that adjusts the position of the light guide and a light guide clamping claw that holds the light guide.

[0093] Furthermore, the number of optical component fixing devices is at least one (in this embodiment, two optical component fixing devices are used as an example for illustration);

[0094] Furthermore, each optical component fixing device includes at least one adjusting shaft;

[0095] Furthermore, the optical temperature measurement system may also include a base 1, with a connecting rod between the base 1 and the adjustment seat 3, so that there is a Z-axis distance between the base 1 and the adjustment seat 3 for configuring the temperature tester 4 and adjusting the temperature tester.

[0096] like Figures 1-5 This is a schematic diagram of the light guide strip temperature measurement system before the position adjustment of the temperature tester 4, the light source, and the light guide.

[0097] like Figures 1-12 As shown, a light guide strip temperature measurement system in this embodiment includes a base 1, a fixing seat 2, a light guide fixing device, a position adjustment device 7, a position adjustment slide, an adjustment seat 3, a temperature tester 4, and a height adjustment device 8.

[0098] The fixed base 2 and the adjusting base 3 are set on the base 1, the temperature tester 4 is placed on the adjusting base 3, and the other side of the adjusting base is provided with a first position adjusting device and a second position adjusting device for adjusting the position of the light source and the heat sink 6.

[0099] Before the test begins, the light guide is first fixed by the first fixing component 201, the second fixing component 202, the first card claw 203 and the second card claw 204; and the light source and heat sink 6 are fixed on the position adjustment device 7; and the temperature tester 4 is fixed by the height adjustment device 8.

[0100] After fixing the light guide, heat sink 6, and temperature tester 4, the LED on the heat sink is lit and left to stand for a period of time. The temperature of the light guide gradually rises until it stabilizes and remains constant. Within a short time, the heat sink 6 is quickly moved away using the first and second position adjustment devices, so that the measurement signal of the temperature tester 4 can directly pass through the through hole 301 to obtain the temperature of the light guide end face.

[0101] Furthermore, by using the position adjustment device 7 and the optical component fixing device, the gap between the heat sink 6 and the light guide end face can be adjusted, thereby obtaining the effect of the gap size on the temperature of the light guide end face.

[0102] Furthermore, by adjusting the light guide bracket (including the bracket color and the distance between it and the light-introducing end face), the influence of the light guide bracket on the temperature of the light-introducing end face can be obtained.

[0103] A second aspect of this application provides a method for temperature measurement of an optical guide strip, specifically including the following steps:

[0104] Step 1: Fix the light guide in the designated position using the optical component fixing device, and at the same time adjust the height adjustment device 9 of the tester so that the test signal of the tester can pass through the adjustment device base 3 and be aligned with the light guide end face;

[0105] Step 2: Move the light source and heat sink until the light source is aligned with the light guide end face;

[0106] Step 3: Turn on the light source and let it stand still for a while;

[0107] Step 4: Quickly remove the heat sink and use a temperature tester to obtain the temperature of the light-guiding end face;

[0108] Step 5: Adjust the distance between the light source and the light-guiding end face, and repeat steps 1 to 4 to obtain the temperature of the light-guiding end face at different distances.

[0109] Steps one through four can be repeated continuously, and the average value of multiple times can be taken as the temperature of the light-introducing end face.

[0110] This invention solves the problem of excessively high temperature in traditional measurement processes by using a non-contact temperature measuring instrument to measure the temperature of the light guide end face, and avoids the risk of light guide ablation due to testing methods.
