DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1-3 shown, the optical fiber array end face detection device in an embodiment of the present utility model includes a bracket 1, a detection fixture 2, an end face detector 3, and a three-way adjustment component 4. The detection fixture 2 is detachably arranged on the top of the bracket 1 and is used for clamping a plurality of optical fiber arrays 5. The end face detector 3 is arranged below the detection fixture 2. The three-way adjustment component 4 is connected to the end face detector 3 and is used to control the three-way movement of the end face detector 3.
[0024] The working principle of the optical fiber array end face detection device is as follows: A plurality of optical fiber arrays 5 are clamped by the detection fixture 2 and placed on the top of the bracket 1, and the end faces of the optical fiber arrays 5 are arranged downward. The three-way adjustment component 4 adjusts the position of the end face detector 3 to keep an appropriate distance from the end face detector 3, and then the three-way adjustment component 4 controls the end face detector 3 to move along the arrangement direction of the plurality of optical fiber arrays 5, sequentially inspecting each optical fiber array 5 and transmitting the end face condition of the optical fiber array 5 to an external display.
[0025] In the above embodiment, the detection fixture 2 of the optical fiber array end face detection device of the present utility model can clamp a plurality of optical fiber arrays 5 at the same time, thereby improving the detection efficiency of the detection device. The detection fixture 2 is detachably connected to the bracket 1, and the detection fixture 2 can be replaced according to the test requirements to adapt to different optical fiber arrays 5. The three-way adjustment component 4 can control the movement of the end face detector 3 to detect a plurality of optical fiber arrays 5.
[0026] In one embodiment, as Figure 3 shown, the detection fixture 2 includes a first clamping plate 21 and a second clamping plate 22. The first clamping plate 21 is detachably connected to the second clamping plate 22, so that a plurality of optical fiber arrays 5 can be conveniently and quickly clamped between the two. A clamping space 23 for clamping the optical fiber array 5 is formed between the first clamping plate 21 and the second clamping plate 22, and an opening 231 is formed on the lower surfaces of the first clamping plate 21 and the second clamping plate 22 for the clamping space 23. The end faces of the optical fiber arrays 5 are located at the opening 231 of the clamping space 23, so that the end face detector 3 can detect the end faces of the optical fiber arrays 5 from the opening 231.
[0027] Magnets 24 are embedded in the opposite surfaces of the first clamping plate 21 and the second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 can be connected by the magnetic force of the magnets 24, so that the quick disassembly and installation of the two can be realized. The lower surface of the detection fixture 2 is provided with an optical fiber array positioning block 25. The optical fiber array positioning block 25 is arranged at the end of the opening 231 and can abut against the optical fiber array 5 to ensure the position of the optical fiber array 5 between the first clamping plate 21 and the second clamping plate 22, thereby improving the detection accuracy.
[0028] The arrangement of the optical fiber array 5 between the first clamping plate 21 and the second clamping plate 22 is as follows: The optical fiber arrays 5 are symmetrically adhered to the two surfaces of a blue film 6. Multiple optical fiber arrays 5 are successively adhered to the two surfaces of the blue film 6, and then the blue film 6 with the optical fiber arrays 5 adhered is clamped in the clamping space 23 formed between the first clamping plate 21 and the second clamping plate 22.
[0029] The optical fiber array positioning block 25 can fix the front and rear positions of multiple optical fiber arrays 5 at one time, so that they are neatly and evenly arranged between the first clamping plate 21 and the second clamping plate 22, so that the end face detector 3 can clearly see multiple optical fiber arrays. There can be two optical fiber array positioning blocks 25, which are respectively arranged at both ends of the opening 231, so as to play a guiding and positioning role in the placement position of the optical fiber array 5 when it is placed into the clamping space 23.
[0030] In an embodiment, as Figure 1 shown, the bracket 1 includes a horizontal bearing plate 11 and vertical support plates 12 arranged at both ends of the horizontal bearing plate 11. A rectangular through hole 111 is opened on the horizontal bearing plate 11. The detection fixture 2 is detachably arranged in the rectangular through hole 111 and the bottom surface of the detection fixture 2 is arranged opposite to the end face detector 3.
[0031] The end face detector 3 has a detection camera 31 and is connected to an external display device. The detection camera 31 is located below the rectangular through hole 111, and the end face detector 3 can move along the length direction of the rectangular through hole 111 so as to sequentially inspect the optical fiber arrays 5 in the detection fixture 2.
[0032] In an embodiment, the three-way adjustment component 4 includes a Y-axis adjustment frame 41, an X-axis adjustment frame 42 and a Z-axis adjustment frame 43. As Figure 1As shown, the X-axis, Y-axis, and Z-axis correspond to the coordinate system in the figure. The Y-axis adjustment bracket 41 is used to move the end face detector 3 in the horizontal direction (i.e., the Y-axis direction). The X-axis adjustment bracket 42 is slidably arranged on the Y-axis adjustment bracket 41 and is used to move the end face detector 3 in the front-back direction (i.e., the X-axis direction), and the X-axis adjustment bracket 42 can move horizontally on the Y-axis adjustment bracket 41. The lower surface of the Z-axis adjustment bracket 43 is fixedly connected to the X-axis adjustment bracket 42, and the upper surface of the Z-axis adjustment bracket 43 is connected to the end face detector 3 and is used to move the end face detector 3 in the vertical direction (i.e., the Z-axis direction).
[0033] The X-axis adjustment bracket 42 and the Z-axis adjustment bracket 43 can be adjustment brackets with cylinders, so as to finely adjust the end face detector 3 in the X-axis and Z-axis directions, so that the detection camera 31 on the end face detector 3 can clearly scan the fiber array 5.
[0034] Furthermore, the Y-axis adjustment bracket 41 includes a fixed base 411, a guide rail 412, and a drive shaft 413. The guide rail 412 is arranged on the fixed base 411 in the horizontal direction, and the X-axis adjustment bracket 42 is slidably arranged on the guide rail 412. The drive shaft 413 is arranged through the X-axis adjustment bracket 42 in parallel with the guide rail 412 and is used to drive the X-axis adjustment bracket 42 to move along the guide rail 412, so as to move along the length direction of the rectangular through hole 111 to detect the fiber array 5. For example: Precision tracks are installed inside both the X-axis adjustment bracket 42 and the Y-axis adjustment bracket 41, so that the X-axis adjustment bracket 42 can slide on the Y-axis adjustment bracket 41. Or, the X-axis adjustment bracket 42 can be threadedly connected to the drive shaft 413, so that when the drive shaft 413 rotates, the X-axis adjustment bracket 42 can move on the Y-axis adjustment bracket 41. One end of the drive shaft 413 is provided with a drive member 4131, which is used to drive the drive shaft 413 to rotate to drive the X-axis adjustment bracket 42, the Z-axis adjustment bracket 43, and the end face detector 3 to move along the guide rail 412 together. Specifically, the drive member 4131 can be a drive handwheel or a drive motor.
[0035] In an embodiment, two guide rails 412 can be provided. The two guide rails 412 are arranged parallel to each other and are connected to the X-axis adjustment bracket 42. The two guide rails 412 can improve the stability of the X-axis adjustment bracket 42 moving on the Y-axis adjustment bracket 41 and prevent it from shifting.
[0036] In summary, the fiber array end face detection device of the present utility model can clamp multiple fiber arrays 5 simultaneously by setting the detection fixture 2, thereby improving the detection efficiency of the detection device. The detection fixture 2 is detachably connected to the bracket 1, and the detection fixture 2 can be replaced according to the needs of the test to adapt to different fiber arrays 5. The detection fixture 2 includes two detachably connected clamping plates, which can improve the replacement speed of the fiber array 5. In addition, the three-way adjustment component 4 can control the position of the end face detector 3 relative to the detection fixture 2 and move relative to it to detect multiple fiber arrays 5. The fiber array end face detection device can reduce the detection difficulty of the fiber array end face, improve the efficiency, and is not easy to damage the fiber array.
