Description

Technical Field

[0001] The utility model relates to the technical field of detection fixtures, in particular to an optical waveguide test fixture. Background Art

[0002] An optical waveguide is a medium device that guides the propagation of light waves. The image output by the optical waveguide is inspected at various stages of optical waveguide production to determine whether the image output of each production link meets the design requirements, thereby ensuring the correct image output of the final product. In order to meet the position requirements of the inspection equipment for the inspected part, the corresponding inspection part bracket must be able to adjust the horizontal plane of the image, and at the same time, it must be able to adjust the vertical and horizontal angles as well as the left and right angles to meet the inspection conditions. Currently, this is mainly achieved by making a dedicated inspection bracket for each product, and then equipping it with special equipment that can adjust the horizontal, pitch, and tilt degrees of freedom for inspection. This results in poor versatility of the inspection bracket and low optical waveguide inspection efficiency. Utility Model Content

[0035] Reference below Figure 1-Figure 5 The optical waveguide test fixture 1000 according to an embodiment of the present invention is described. The optical waveguide test fixture 1000 includes a bracket 100 , a clamping mechanism 200 and an adjustment mechanism 300 . The bracket 100 includes a first side a where the optical waveguide 1 is disposed and a second side b facing away from the optical waveguide 1 .

[0036] Please refer to Figure 1-Figure 2 Furthermore, the clamping mechanism 200 is arranged on the bracket 100, and the clamping mechanism 200 includes at least a fixed shaft 210, a horizontal adjustment shaft 220 and a movable clamping shaft 230. The fixed shaft 210 is used to position and support the optical waveguide 1, the horizontal adjustment shaft 220 is used to adjust the horizontal position of the optical waveguide 1, and the movable clamping shaft 230 cooperates with the fixed shaft 210 and the horizontal adjustment shaft 220 to clamp and fix the optical waveguide 1.

[0037] It can be understood that when the optical waveguide clamping device is used to fix the optical waveguide 1, the fixed shaft 210 and the horizontal adjustment shaft 220 can be located on the same side of the optical waveguide 1, and the movable clamping shaft 230 can be located on the other side opposite the optical waveguide, so that the fixed shaft 210 can position and support the optical waveguide 1, and the horizontal adjustment shaft 220 can adjust the horizontal position of the optical waveguide 1. After adjusting the horizontal position of the optical waveguide 1, the movable clamping shaft 230 is adjusted so that the movable clamping shaft 230 cooperates with the fixed shaft 210 and the horizontal adjustment shaft 220 to clamp and fix the optical waveguide 1.

[0038] Please continue to refer to Figure 1-Figure 2 Furthermore, the adjustment mechanism 300 is arranged on the bracket 100, and the adjustment mechanism 300 includes a left and right swing angle adjustment member 310 and an up and down pitch angle adjustment member 320, wherein the left and right swing angle adjustment member 310 can be used to adjust the left and right swing angle of the optical waveguide, and the up and down pitch angle adjustment member 320 can be used to adjust the up and down pitch angle of the optical waveguide.

[0039] It should be noted that the clamping mechanism 200 and the adjusting mechanism 300 can be located on the first side a of the bracket 100, or on the second side b of the bracket 100, or one of the clamping mechanism 200 and the adjusting mechanism 300 can be located on the first side a of the bracket 100, and the other can be located on the second side b of the bracket 100. The embodiment of the present utility model does not limit this.

[0040] In actual research, the inventors found that optical waveguide products generally require inspection of output images at various stages of production. In order to meet the position requirements of the optical waveguide for the inspection equipment, the corresponding inspection component bracket needs to be able to adjust with multiple degrees of freedom to meet the inspection requirements. In addition, due to the large variety of optical waveguide products and their different appearances, in order to reduce costs and facilitate the management of the test bracket, versatility is also an important factor to consider when designing the test bracket.

[0041] In view of this, according to the optical waveguide test fixture 1000 of the embodiment of the present invention, a clamping mechanism 200 and an adjustment mechanism 300 are provided on the bracket 100, and the clamping mechanism 200 includes a fixed shaft 210, a horizontal adjustment shaft 220 and a movable clamping shaft 230. The movable clamping shaft 230 cooperates with the fixed shaft 210 and the horizontal adjustment shaft 220 to form three-point contact with the optical waveguide to clamp and fix the optical waveguide, thereby clamping optical waveguides of any shape, thereby improving the versatility of the optical waveguide test fixture 1000. In addition, by providing the adjustment mechanism 300 on the bracket 100, the adjustment mechanism 300 includes a left and right swing angle adjustment member 310 and an up and down pitch angle adjustment member 320, so that the left and right swing angle and the up and down pitch angle of the optical waveguide can be adjusted on the bracket 100 using the adjustment mechanism 300, making the fixing and adjustment of the optical waveguide easier, thereby further improving the detection efficiency of the optical waveguide.

[0042] Please continue to refer to Figure 1-Figure 2 In some embodiments, a test window 110 is provided on the bracket 100 , the fixed shaft 210 and the horizontal adjustment shaft 220 are provided on one side of the test window 110 , and the movable clamping shaft 230 is provided on the other side opposite to the test window 110 .

[0043] It can be understood that the test window 110 is a hollow hole that passes through the bracket 100, so that light can be emitted from the first side a of the bracket 100 to the second side b, or from the second side b of the bracket 100 to the first side a, so as to detect the optical waveguide 1.

[0044] In addition, the fixed shaft 210 and the horizontal adjustment shaft 220 are arranged on one side of the test window 110, and the movable clamping shaft 230 is arranged on the other side opposite to the test window 110. This means that when the optical waveguide clamping device is used to fix the optical waveguide 1, the fixed shaft 210 and the horizontal adjustment shaft 220 can be located on the same side of the optical waveguide 1, that is, the fixed shaft 210 and the horizontal adjustment shaft 220 are arranged on one side of the test window 110, and the movable clamping shaft 230 can be located on the other side opposite to the optical waveguide 1, that is, the movable clamping shaft 230 is arranged on the other side opposite to the test window 110, so that the fixed shaft 210 can position and support the optical waveguide 1, and the horizontal adjustment shaft 220 can adjust the horizontal position of the optical waveguide 1. After the horizontal position of the optical waveguide 1 is adjusted, the movable clamping shaft 230 is adjusted so that the movable clamping shaft 230 cooperates with the fixed shaft 210 and the horizontal adjustment shaft 220 to clamp and fix the optical waveguide 1.

[0045] Please refer to Figure 3 and Figure 4 In some embodiments, the horizontal adjustment shaft 220 includes an eccentric shaft, which includes a first shaft portion 221, a second shaft portion 222, and a connecting portion 223 connecting the first shaft portion 221 and the second shaft portion 222. The first shaft portion 221 and the second shaft portion 222 are eccentrically arranged to adjust the horizontal position of the optical waveguide 1.

[0046] It should be noted that the first shaft portion 221 and the second shaft portion 222 are eccentrically arranged. Therefore, when the first shaft portion 221 is rotated, the movement trajectory of the second shaft portion 222 is different from that of the first shaft portion 221. When the optical waveguide 1 contacts different positions of the second shaft portion 222, the position of the optical waveguide changes, thereby adjusting the horizontal position of the optical waveguide. Therefore, using an eccentric shaft to adjust the horizontal position of the optical waveguide 1 makes it easier to adjust the optical waveguide 1, thereby further improving the detection efficiency of the optical waveguide 1.

[0047] like Figures 1-4 As shown, the connecting portion 223 and the first shaft portion 221 can be concentrically arranged, or the connecting portion 223 and the second shaft portion 222 can be concentrically arranged, and the connecting portion 223 can also be eccentrically arranged with respect to both the first shaft portion 221 and the second shaft portion 222. The first shaft portion 221, the second shaft portion 222 and the connecting portion 223 can all be cylindrical, and this embodiment of the utility model is not limited thereto.

[0048] Please refer to Figures 1-4In some optional embodiments, a first through hole 120 is provided on the bracket 100, and the first shaft portion 221 passes through the bracket 100 through the first through hole 120. The connecting portion 223 is larger than the first through hole 120 so that the connecting portion 223 is provided on the first side a of the bracket 100. The horizontal adjustment shaft 220 also includes a locking member, which is provided on the second side b of the bracket 100. The locking member cooperates with the connecting portion 223 to fix the first shaft portion 221.

[0049] Thus, by providing the first through hole 120 and making the connection portion 223 larger than the first through hole 120, the first shaft portion 221 can pass through the first through hole 120 to the second side b of the bracket 100. The connection portion 223 and the second shaft portion 222 remain on the first side a of the bracket 100 to adjust the horizontal position of the optical waveguide. The locking member located on the second side b of the bracket 100 then secures the first shaft portion 221 to maintain a fixed horizontal position of the optical waveguide, thereby ensuring the stability of the optical waveguide test fixture 1000 in clamping the optical waveguide 1. Furthermore, the location of the locking member on the second side b of the bracket 100 prevents interference with the optical waveguide 1.

[0050] Please continue to refer to Figures 1-4 In some optional embodiments, an external thread is provided on the first shaft portion 221, and the locking member includes a clamping nut 224 and a compression spring 225. The clamping nut 224 and the compression spring 225 are provided on the first shaft portion 221, and the compression spring 225 is provided between the bracket 100 and the clamping nut 224. An internal thread matching the external thread is provided in the clamping nut 224. By adjusting the position of the clamping nut 224 on the first shaft portion 221, the pressure between the compression spring 225 and the bracket 100 is adjusted to fix or release the first shaft portion 221.

[0051] It can be understood that since the size of the connecting portion 223 is larger than the size of the first through hole 120, when the first shaft portion 221 passes through the first through hole 120 and extends to the second side b of the bracket 100, the connecting portion 223 can abut against the first side a of the bracket 100, and the position of the clamping nut 224 on the first shaft portion 221 can be adjusted, so that the position of the compression spring 225 on the first shaft portion 221 can be adjusted, so that the compression spring 225 abuts against the second side b of the bracket 100, and the clamping nut 224 is further adjusted to adjust the pressure between the compression spring 225 and the bracket 100, thereby achieving the fixing and release of the first shaft portion 221.

[0052] Therefore, after the horizontal adjustment shaft 220 completes the adjustment of the horizontal position of the optical waveguide 1, the first shaft portion 221 can be fixed by the clamping nut 224 and the clamping spring 225, thereby fixing the position of the horizontal adjustment shaft 220 and fixing the horizontal position of the optical waveguide 1. The structure and operation of the horizontal adjustment shaft 220 are simple, which can further improve the detection efficiency of the optical waveguide 1.

[0053] Please continue to refer to Figures 1-4 In some optional embodiments, the horizontal adjustment shaft 220 further includes a knob portion 226, which is disposed at an end of the first shaft portion 221 away from the bracket 100. Thus, the provision of the knob portion 226 facilitates adjustment of the first shaft portion 221, thereby facilitating adjustment of the horizontal position of the optical waveguide 1 by the horizontal adjustment shaft 220, further improving the detection efficiency of the optical waveguide 1.

[0054] Please refer to Figure 5 In some embodiments, the movable clamping shaft 230 includes a rotating shaft 231, a rotating arm 232, a movable shaft 233, a fixed column 234 and a tension spring 235, wherein the rotating shaft 231 is arranged on the bracket 100, and the rotating shaft 231 can rotate on the bracket 100, one end of the rotating arm 232 is fixed to the rotating shaft 231, and the movable shaft 233 is fixed to the other end of the rotating arm 232, the movable shaft 233 can rotate around the rotating shaft 231, and the fixed column 234 is fixed to the bracket 100; one end of the tension spring 235 is fixed to the fixed column 234, and the other end is fixed to the movable shaft 233. When the optical waveguide is clamped by using the fixed shaft 210, the horizontal adjustment shaft 220 and the movable clamping shaft 230, the tension spring 235 can apply a force to the movable shaft 233 toward the horizontal adjustment shaft 220 or the fixed shaft 210 to clamp the optical waveguide 1.

[0055] It should be noted that the movable shaft 233 is used to cooperate with the fixed shaft 210 and the horizontal adjustment shaft 220 to clamp and secure the optical waveguide 1. After adjusting the position of the optical waveguide 1, the movable shaft 233 is moved to the appropriate position. At this time, because one end of the tension spring 235 is fixed to the fixed column 234 and the other end is fixed to the movable shaft 233, the tension spring 235 can apply an elastic force to the movable shaft 233, so that the movable shaft 233 exerts a force on the optical waveguide 1 toward the horizontal adjustment shaft 220 or the fixed shaft 210, thereby clamping the optical waveguide 1.

[0056] It can be understood that since the movable shaft 233 is connected to one end of the rotating arm 232, and the other end of the rotating arm 232 is connected to the rotating shaft 231, the movable shaft 233 can rotate with the rotating shaft 231 as a fulcrum, that is, by moving the movable shaft 233, the movable shaft 233 rotates around the rotating shaft 231, thereby clamping and releasing the optical waveguide. Moreover, when a variety of optical waveguide products are tested, the movable shaft 233 can be moved to different positions to fix optical waveguides of different shapes, further improving the versatility of the optical waveguide test fixture 1000.

[0057] Please refer to Figure 1-Figure 5 In some optional embodiments, a second through hole 130 is provided on the bracket 100. The shape of the second through hole 130 is the same as the movable trajectory of the movable shaft 233. The rotating shaft 231, the rotating arm 232, the fixing column 234 and the tension spring 235 are all provided on the second side b of the bracket 100. The movable shaft 233 passes through the second through hole 130 and extends to the first side a of the bracket 100 to fix the optical waveguide.

[0058] Therefore, by arranging the rotating shaft 231, the rotating arm 232, the fixing column 234 and the tension spring 235 on the second side b of the bracket 100, only the movable shaft 233 is extended through the second through hole 130 to the first side a of the bracket 100 to fix the optical waveguide, it is possible to avoid interference of the rotating shaft 231, the rotating arm 232, the fixing column 234 and the tension spring 235 with the optical waveguide 1.

[0059] It can be understood that the movable trajectory of the movable shaft 233 is an arc-shaped trajectory with the rotating shaft 231 as the center point and the rotating arm 232 as the radius, that is, the second through hole 130 is an arc-shaped hole. Of course, the present invention is not limited to this, and the second through hole 130 can also be a hole of other shapes.

[0060] It should be noted that the rotating shaft 231, the rotating arm 232, the fixed column 234 and the tension spring 235 are all arranged on the second side b of the bracket 100, which means that the main parts of the rotating shaft 231, the rotating arm 232, the fixed column 234 and the tension spring 235 are roughly located on the second side b of the bracket 100, wherein the rotating shaft 231 can also be set through the bracket 100, and the rotating shaft 231 is set on the bracket 100 using a nut sleeved on the rotating shaft 231, so that the rotating shaft 231 can rotate on the bracket 100, and the fixed column 234 can also pass through the bracket 100 and be fixed on the bracket 100.

[0061] Please refer to Figure 1-Figure 5In some optional embodiments, an anti-slip structure is provided on one end of the movable shaft 233 away from the rotating arm 232. Thus, when the movable shaft 233 is moved, the anti-slip structure can increase the friction between the movable shaft 233 and a human hand or machine, thereby further improving the stability of the optical waveguide test fixture 1000.

[0062] In some embodiments, a third through hole 140 and a fourth through hole 150 are provided on the bracket 100, and the left and right swing angle adjustment member 310 includes a left and right swing angle adjustment shaft 311 and a left and right swing angle adjustment knob 312. The left and right swing angle adjustment knob 312 is sleeved on one end of the left and right swing angle adjustment shaft 311 and is provided on the second side b of the bracket 100. The left and right swing angle adjustment shaft 311 passes through the third through hole 140 to the first side a of the bracket 100, wherein a first thread is provided in the third through hole 140, and a second thread matching the first thread is provided on the left and right swing angle adjustment shaft 311. Rotating the left and right swing angle adjustment knob 312 drives the left and right swing angle adjustment shaft 311 to rotate, adjusting the left and right swing angle adjustment shaft 311 to extend to the first side a of the bracket 100. , so as to adjust the left and right swing angles of the optical waveguide 1; the up and down pitch angle adjustment member 320 includes an up and down pitch angle adjustment shaft 321 and an up and down pitch angle adjustment knob 322, the up and down pitch angle adjustment knob 322 is sleeved on one end of the up and down pitch angle adjustment shaft 321, and is arranged on the second side b of the bracket 100, the up and down pitch angle adjustment shaft 321 passes through the fourth through hole 150 to the first side a of the bracket 100, wherein a third thread is provided in the fourth through hole 150, and a fourth thread matching the third thread is provided on the up and down pitch angle adjustment shaft 321, rotating the up and down pitch angle adjustment knob 322 drives the up and down pitch angle adjustment shaft 321 to rotate, adjusts the length of the up and down pitch angle adjustment shaft 321 extending to the first side a of the bracket 100, so as to adjust the up and down pitch angles of the optical waveguide 1.

[0063] Therefore, by setting the third through hole 140 on the bracket 100, the left and right swing angle adjustment knob 312 can be set on the second side b of the bracket 100, and the left and right swing angle adjustment shaft 311 extends through the third through hole 140 to the first side a of the bracket 100 to adjust the left and right swing angle of the optical waveguide, thereby avoiding the left and right swing angle adjustment knob 312 from interfering with the optical waveguide. Similarly, setting the fourth through hole 150 on the bracket 100 can also avoid the up and down pitch angle adjustment knob 322 from interfering with the optical waveguide.

[0064] It should be noted that the third through hole 140 and the left-right swing angle adjustment shaft 311 are provided with matching first and second threads, and the left-right swing angle adjustment knob 312 is mounted on the left-right swing angle adjustment shaft 311. Rotating the left-right swing angle adjustment knob 312 causes the left-right swing angle adjustment shaft 311 to rotate, thereby adjusting the position of the left-right swing angle adjustment shaft 311 extending from the third through hole 140 to the first side a, thereby adjusting the left-right swing angle of the optical waveguide and fixing the left-right swing angle adjustment shaft 311. Similarly, the fourth through hole 150 and the vertical pitch angle adjustment shaft 321 are provided with matching third and fourth threads. The vertical pitch angle adjustment knob 322 is mounted on the vertical pitch angle adjustment shaft 321. Rotating the vertical pitch angle adjustment knob 322 causes the vertical pitch angle adjustment shaft 321 to rotate, thereby adjusting the position of the vertical pitch angle adjustment shaft 321 extending from the fourth through hole 150 to the first side a, thereby adjusting the vertical pitch angle of the optical waveguide and fixing the vertical pitch angle adjustment shaft 321.
