[0031] Understandably, referring to Figure 1 , Figure 2 and Figure 6The optical fiber assembly auxiliary device of this utility model includes a positioning mechanism 100 and a moving mechanism 200. The positioning mechanism 100 includes a positioning platform 110, a fixing block 120, and a sliding block 130. The positioning platform 110 has a first positioning groove 111 for accommodating an optical fiber 310. The fixing block 120 is fixedly connected to the upper end of the positioning platform 110 and is threadedly connected to a first screw 121, which can abut against the optical fiber 310. The sliding block 130 is slidably connected to the positioning platform 110 and has a second positioning groove 131 for accommodating a silicon wafer 320. The positioning platform 110 is threadedly connected to a second screw 132, which is connected to the sliding block 130 to push the sliding block 130 to slide towards or away from the first positioning groove 111. The moving mechanism 200 is used to drive the positioning mechanism 100 to move.
[0032] The positioning stage 110 has a first positioning groove 111, in which the optical fiber 310 is arranged to define its position. The fixing block 120 is fixedly connected to the upper end of the positioning stage 110. The first screw 121 is threadedly connected to the fixing block 120 and is located above the first positioning groove 111. By driving the first screw 121 to rotate, the first screw 121 can move axially, thereby abutting the first screw 121 against the optical fiber 310 and fixing the optical fiber 310 on the first positioning groove 111, preventing the position of the optical fiber 310 from shifting. Then, the positioning mechanism 100 is driven to move by the moving mechanism 200, which can easily adjust the position of the optical fiber 310 and facilitate positioning of the optical fiber 310. The sliding block 130 is slidably connected to the positioning stage 110. The sliding block 130 has a second positioning groove 131 for accommodating the silicon wafer 320. A second screw 132 is connected to the sliding block 130 and is threadedly connected to the positioning stage 110. When the second screw 132 is driven to rotate, it can move axially, allowing it to push the sliding block 130 to move closer to or further away from the first positioning groove 111. This facilitates the adjustment of the position of the silicon wafer 320 on the optical fiber 310, enabling the silicon wafer 320 to move stably and improving the convenience of adjustment.
[0033] It should be noted that the positioning mechanism 100 is positioned under a microscope. First, the optical fiber 310 is placed in the first positioning groove 111. Then, the first screw 121 is screwed into the fixing block 120, pressing the optical fiber 310 firmly into the first positioning groove 111, thus stabilizing the optical fiber 310 in the first positioning groove 111. Next, the moving mechanism 200 drives the positioning mechanism 100 to move, ensuring the optical fiber 310 is accurately positioned under the microscope for easy observation and adjustment. The silicon wafer 320 is placed in the second positioning groove 131. The second screw 132 drives the sliding block 130 to move closer to the first positioning groove 111, ensuring the silicon wafer 320 is accurately positioned on the optical fiber 310. Then, adhesive is applied to fix the silicon wafer 320 onto the optical fiber 310, stabilizing it and replacing repeated manual adjustments, thus improving assembly efficiency and quality.
[0034] The microscope has pre-set positioning lines. After the first screw 121 presses the optical fiber 310 into the first positioning groove 111, the positioning mechanism 100 is driven to move by the moving mechanism 200 so that the optical fiber 310 can be aligned with the positioning lines on the microscope, so as to position the relative position of the optical fiber 310 and the silicon wafer 320 and improve the assembly quality.
[0035] In addition, the moving mechanism 200 can be a robotic arm, multiple linear cylinders, multiple linear slide modules, etc., which will not be described in detail here.
[0036] Understandably, referring to Figure 2 and Figure 6 The positioning stage 110 has a sliding groove 112, and the sliding block 130 is slidably connected to the sliding groove 112. By setting the sliding block 130 to be slidably connected in the sliding groove 112, the sliding block 130 can abut against the side wall of the sliding groove 112, so that the sliding block 130 can maintain a stable movement trajectory when sliding in the sliding groove 112, avoiding the sliding block 130 from deviating or shaking during the sliding process, which helps to improve the movement accuracy of the silicon wafer 320 and improve the assembly quality of the optical fiber 310.
[0037] Specifically, refer to Figure 2 A guide rod 133 is fixedly connected to the slide groove 112, and a sliding block 130 is slidably connected to the guide rod 133. The guide rod 133 is fixedly connected to the slide groove 112. By setting the sliding block 130 to be slidably connected to the guide rod 133, the sliding block 130 can smoothly slide along the length direction of the guide rod 133. This limits the sliding direction of the sliding block 130, prevents positional deviation of the sliding block 130, enhances the motion stability between the sliding block 130 and the slide groove 112, makes the entire positioning mechanism 100 more stable and reliable, and improves the assembly yield.
[0038] In addition, the guide rod 133 can reduce the frictional resistance during the sliding process, making it easier for operators to drive the sliding block 130 to move, reducing the difficulty of operation and labor intensity, and further improving assembly efficiency.
[0039] Specifically, refer to Figure 2 and Figure 6 The guide rods 133 are arranged in multiple intervals, and the sliding block 130 is slidably connected to the multiple guide rods 133. The multiple guide rods 133 provide more stable and precise guiding support for the sliding block 130, which can more effectively restrict the degree of freedom of movement of the sliding block 130 in various directions, reduce the instability such as shaking and displacement that may occur during the sliding process, make the position adjustment of the silicon wafer 320 more precise, and improve the assembly accuracy.
[0040] In addition, multiple guide rods 133 jointly undertake the sliding guidance function of the sliding block 130, which disperses the friction generated by the sliding block 130 during the sliding process, reduces the wear rate of a single guide rod 133, extends the service life of the guide rod 133, and improves the reliability and stability of the device.
[0041] Understandably, referring to Figure 2 and Figure 6 The lower end face of the first screw 121 is set as a plane, which can abut against the optical fiber 310. By setting the lower end face of the first screw 121 as a plane, when the first screw 121 is screwed into the fixing block 120 and moves downward to abut against the optical fiber 310, the pressure applied to the optical fiber 310 can be more effectively distributed, avoiding damage to the optical fiber 310 due to excessive local pressure. It also reduces the positional displacement of the optical fiber 310 due to loosening during assembly, allowing the optical fiber 310 to be more firmly fixed on the first positioning groove 111, thereby improving the assembly accuracy and yield.
[0042] Understandably, referring to Figure 1 ,as well as Figures 3 to 6The moving mechanism 200 includes a translation component 210 and a lifting component 220. A positioning mechanism 100 is connected to the movable end of the lifting component 220, which in turn is connected to the movable end of the translation component 210. The translation component 210 drives the lifting component 220 to move horizontally, and the lifting component 220 drives the positioning mechanism 100 to move vertically. The translation component 210 drives the lifting component 220 to move horizontally, allowing the positioning mechanism 100 to be adjusted horizontally, facilitating the rapid and accurate movement of the optical fiber 310 and silicon wafer 320 under the microscope, thus improving operational convenience and efficiency. The lifting component 220 drives the positioning mechanism 100 to move vertically. It lowers the positioning mechanism 100 to a suitable height, facilitating the placement of the optical fiber 310 and silicon wafer 320 by the operator. When observing and adjusting the relative positions of the optical fiber 310 and silicon wafer 320, it raises the positioning mechanism 100 to a clear field of view within the microscope, enabling accurate observation and fine-tuning, thus improving assembly precision and quality. By cooperating with the translation component 210 and the lifting component 220, the positioning mechanism 100 can be flexibly adjusted in three-dimensional space, which improves the practicality and versatility of the fiber optic assembly auxiliary device, reduces the difficulty and error of manual assembly, and improves the yield rate of assembly.
[0043] Specifically, refer to Figure 3 and Figure 6 The translation component 210 includes a first fixed base 211, a first slider 212, and a second slider 213. The first slider 212 is slidably connected to the first fixed base 211, and the second slider 213 is slidably connected to the first slider 212. The sliding directions of the first slider 212 and the second slider 213 are perpendicular to each other. The first fixed base 211 is threadedly connected to a first adjusting rod 214, which is used to push the first slider 212 to slide. The second slider 213 is threadedly connected to a second adjusting rod 215, which is used to pull the second slider 213 to slide. The first slider 212 is slidably connected to the first fixed base 211, and the second slider 213 is slidably connected to the first slider 212. By driving the first adjusting rod 214 to rotate, the first adjusting rod 214 can push the first slider 212 to slide on the first fixed base 211 along the axial direction. By driving the second adjusting rod 215 to rotate, the second adjusting rod 215 can pull the second slider 213 to slide on the first slider 212 along the axial direction. This enables the positioning mechanism 100 to move in two mutually perpendicular directions in the horizontal plane, improving the positional flexibility of the positioning mechanism 100, facilitating the movement of the positioning mechanism 100 under the microscope, and improving the convenience of operation.
[0044] It should be noted that the first adjusting rod 214 is threadedly connected to the first fixed seat 211, and the end of the first screw 121 abuts against the first slider 212, so that when the first adjusting rod 214 is driven to rotate, the first adjusting rod 214 can push the first slider 212 to move on the first fixed seat 211 axially. The second adjusting rod 215 is threadedly connected to the second fixed seat 221, and the end of the second screw 132 abuts against the first fixed seat 211, so that when the second adjusting rod 215 is driven to rotate, the second adjusting rod 215 can pull the second slider 213 to move on the first slider 212 axially.
[0045] Specifically, refer to Figure 1 ,as well as Figures 3 to 6 The lifting assembly 220 includes a second fixed seat 221 and a third slider 222. The second fixed seat 221 is fixedly connected to the second slider 213. The third slider 222 is slidably connected to the second fixed seat 221 in the vertical direction. The positioning mechanism 100 is connected to the third slider 222. The second fixed seat 221 is rotatably connected to a connecting block 223. The second fixed seat 221 is threadedly connected to a third adjusting rod 224. One end of the connecting block 223 abuts against the third slider 222, and the other end of the connecting block 223 abuts against the end of the third adjusting rod 224. The third adjusting rod 224 is used to drive the connecting block 223 to rotate. The second fixed base 221 is fixedly connected to the second slider 213, and the third slider 222 is slidably connected to the second fixed base 221. The connecting block 223 is hinged to the second fixed base 221, and one end of the connecting block 223 abuts against the third slider 222, and the other end abuts against the end of the third adjusting rod 224. By driving the third adjusting rod 224 to rotate, the third adjusting rod 224 can move axially, thereby driving the connecting block 223 to rotate, so that the connecting block 223 can push the third slider 222 to rise and fall, thereby realizing the lifting and lowering adjustment of the positioning mechanism 100, which facilitates moving the positioning mechanism 100 to the microscope and improves the convenience of operation.
[0046] Specifically, refer to Figure 5 and Figure 6 Both ends of the connecting block 223 are provided with abutment portions 225, which are hemispherical in shape. The two abutment portions 225 abut against the ends of the third slider 222 and the third adjusting rod 224, respectively. By providing abutment portions 225 at both ends of the connecting block 223 and setting the shape of the abutment portions 225 to hemispherical, the contact points between the hemispherical abutment portions 225 and the ends of the third slider 222 and the third adjusting rod 224 can flexibly change with the rotation of the connecting block 223. This reduces friction during the sliding process, avoids wear or damage to components due to excessive local pressure, extends service life, and improves the reliability of the lifting assembly 220.
[0047] Understandably, referring to Figure 1The movable end of the moving mechanism 200 is provided with a mounting platform 230, which has a mounting groove 231. The positioning mechanism 100 is arranged in the mounting groove 231. Both sides of the mounting groove 231 are threadedly connected to a third screw 232, which can abut against the positioning mechanism 100. The mounting platform 230 is connected to the movable end of the moving mechanism 200, and the mounting groove 231 is provided for the positioning mechanism 100. Then, the third screw 232 is driven to rotate so that it can screw into the mounting groove 231 and abut against the positioning mechanism 100, so that the positioning mechanism 100 can be stably positioned in the mounting groove 231. By setting the positioning mechanism 100 to be installed in the mounting groove 231, the installation and disassembly of the positioning mechanism 100 can be facilitated, and the positioning mechanism 100 can be easily removed from the mounting groove 231, reducing maintenance difficulty and cost.
[0048] In addition, a third screw 232 is provided on both sides of the mounting groove 231. The two third screws 232 work together to make the position of the positioning mechanism 100 in the mounting groove 231 flexibly adjustable, which helps to improve the positional flexibility of the positioning mechanism 100, adapt to the position of the microscope, and improve the convenience of use.
[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
