Technical Field
[0001] This utility model belongs to the field of optical device welding technology, and specifically relates to an optical device welding positioning fixture. Background Technology
[0002] Optical devices refer to a class of key components used in fields such as optical communication, optical imaging, laser measurement, and medical testing to generate, modulate, transmit, receive, or control optical signals. Common examples include lasers, photodetectors, optical fibers, optical modulators, optical switches, wavelength division multiplexers, and fiber optic connectors. They play a central role in modern optoelectronic systems and are widely used in fiber optic communication, lidar, sensing, display, and industrial automation. They are fundamental devices for achieving optoelectronic signal interconnection, precise control of optical signals, and efficient transmission.
[0003] Optical device welding positioning fixtures are mainly used for positioning and fixing optoelectronic components (such as lasers, fiber couplers, optical modules, etc.) during the assembly and welding process. They ensure that there are no positional errors such as offset, tilt, or rotation during high-temperature welding, laser welding, or hot pressing, and maintain their alignment with the connecting structure (such as optical fiber, ceramic sleeve, PCB pad).
[0004] Currently, most of the fixtures used for welding optical devices are fixed clamping structures. Although they can maintain the stability of the optical devices during the welding process, they are not convenient for quickly adjusting the position of the optical devices and aligning them according to the position of the integrated board to be welded. In addition, their clamps are generally of fixed models, making it difficult to be compatible with optical devices of different types and sizes. Utility Model Content
[0005] To address the above problems, the purpose of this utility model is to provide a welding positioning fixture for optical devices, which solves the problem that most fixtures used for welding optical devices are fixed clamping structures. Although they can maintain the stability of the optical devices during the welding process, they are not convenient for quickly adjusting the position of the optical devices and aligning them according to the position of the integrated board to be welded. In addition, their clamps are generally of fixed models, making it difficult to be compatible with optical devices of different types and sizes.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0035] like Figure 1 — Figure 5As shown: A welding and positioning fixture for optical devices includes a support platform 1. A fixing clamping mechanism 2 is provided on the upper side of the support platform 1. A clamping adjustment mechanism 3 is provided on one side of the upper side of the support platform 1. The clamping adjustment mechanism 3 includes a fixing block 31, a rail 32, a first screw 33, a motor 34, a slide table 35, a first electric telescopic rod 36, a first connecting block 37, a second electric telescopic rod 38, and a clamping plate 39. The fixing blocks 31 are symmetrically fixed on the upper side of the support platform 1. The first screw 33 is rotatably arranged between the fixing blocks 31. A motor 34 is fixedly arranged on the side of one of the fixing blocks 31. The output end of the motor 34 passes through the fixing block 31 and is fixedly connected to the first screw 33. A slide table 3 is threadedly arranged on the outer side of the first screw 33. 5. An electric telescopic rod 36 is fixedly installed on the side of the slide table 35. A connecting block 37 is fixedly installed on the side of the electric telescopic rod 36 facing the fixed clamping mechanism 2. An electric telescopic rod 38 is fixedly installed on the upper side of the connecting block 37. A clamping plate 39 is fixedly installed on the lower side of the output end of the electric telescopic rod 38. The clamping plate 39 includes a disc 391. The disc 391 is located at the lower end of the output end of the electric telescopic rod 38. Clamping mechanisms 392 are equidistantly arranged around the disc 391. The position of the optical device can be adjusted horizontally and vertically to quickly position and align the optical device to the welding point. Then, welding can be performed by welding torch. There are multiple clamping mechanisms 392, which can clamp different optical devices simultaneously. The optical device, the clamping mechanism 392 includes a second connecting block 3921, which is disposed on the side of the disk 391. A support block 3922 is fixedly disposed on the side of the second connecting block 3921 away from the disk 391. A movable groove 3923 is formed on the side of the support block 3922 away from the second connecting block 3921. A second screw 3924 is rotatably disposed on the inner side of the movable groove 3923. A symmetrical threaded drive 3926 is disposed on the outer side of the second screw 3924. The threaded rotation direction of the 3926 is opposite to that of the second screw 3924. A knob 3925 is disposed on both sides of the support block 3922. The knob 3925 is fixedly connected to the second screw 3924. The optical device is placed on the 3926. In between, turning knob 3925 causes screw 3924 to rotate, causing screws 3926 to move closer together until they clamp the optical device. The shapes of screws 3926 vary depending on the specific clamping mechanism 392, allowing for targeted clamping of specific optical devices. The fixed clamping mechanism 2 includes three electrically operated telescopic rods with their output ends opposite each other. Each output end of the three electric telescopic rods is fixedly connected to a clamping rod. Activating the three electric telescopic rods causes their output ends to push the clamping rods, clamping the main board. A rail 32 is fixedly installed on the lower side between the fixed blocks 31. The rail 32 is fixedly installed on the upper side of the support platform 1, and the slide 35 is installed on the upper side of the rail 32.The slide table 35 is slidably engaged with the rail rod 32, providing slidable support. The connecting block 3921 is inserted into the side of the disc 391. A knob 398 is threadedly connected to the lower side of the disc 391 corresponding to the connecting block 3921. The knob 398 is threaded through the disc 391 and pressed against the connecting block 3921. Loosening the knob 398 allows the connecting block 3921 to be pulled out directly from the side of the disc 391, facilitating quick replacement of the clamping mechanism 392. The upper center of the disc 391 is rotatably connected to the output end of the electric telescopic rod 38. A fixed plate 393 is tightly attached to the upper side of the disc 391. The fixed plate 393 is connected to the electric telescopic rod... The output end of the second 38 is fixedly connected. The upper side of the fixed disk 393 has equidistant, continuous locking holes 394, each corresponding to a clamping mechanism 392. One side of the upper surface of the disk 391 has a circular groove 395 corresponding to one of the locking holes 394. A spring 396 is disposed inside the circular groove 395, and a retaining ball 397 is fixedly disposed on the upper side of the spring 396. The upper side of the retaining ball 397 engages with the locking hole 394. Rotating the disk 391 causes the spring 396 and retaining ball 397 to rotate, allowing the retaining ball 397 to engage with different locking holes 394, thus adjusting the relative position of the outer clamping mechanism 392 as needed.
[0036] Working principle and usage process of this utility model:
[0037] In use, place the optical components and motherboard between the clamping rods. Activate the electric telescopic rod three; its output pushes the clamping rods to clamp the motherboard. Then, select the corresponding clamping mechanism 392 and place the optical components between 3926. Turn the knob one 3925 to rotate the screw two 3924, causing 3926 to move closer together until the optical components are clamped. Then, activate the motor 34; its output drives the screw one 33 to rotate. The threaded transmission of the screw one 33 causes the slide table 35 to slide horizontally along the rail 32. Activate the electric telescopic rod one 36; its output pushes the connecting block one 37 to move horizontally. Activate the electric telescopic rod two 38; its output moves the clamping plate 39 up and down. This allows for horizontal and vertical adjustment of the optical device's position, enabling rapid positioning and alignment with the welding point. Welding can then be performed using a welding torch. Multiple clamping mechanisms 392 can simultaneously clamp different optical devices. Each clamping mechanism 392 has a different 3926 configuration, allowing for targeted clamping of specific optical devices. Rotating the disc 391 causes the spring 396 and the retaining ball 397 to rotate. The retaining ball 397 can engage different retaining holes 394, thus adjusting the relative position of the outer clamping mechanism 392 as needed. Loosening the knob 398 allows the connecting block 3921 to be pulled directly from the side of the disc 391, facilitating quick replacement of the clamping mechanism 392.
