Description

Technical Field

[0002] Optical transmitting and receiving components have become essential parts of fiber optic communication. BOSA optical devices combine components such as LDs, PIN-TIAs, and WMD-Filters. Through proper structural design and assembly, the devices can be fabricated. During assembly, the laser diode (LD) needs to be inserted into the BOSA base and fixed using laser welding.

[0003] By comparing a BOSA optical device bonding device with patent publication number CN208600899U, this solution has multi-directional operational flexibility, improves the adaptability of laser diode insertion, and significantly improves insertion stability. However, when welding the receiving end after welding the transmitting end of the base, this device requires removing the base, rotating the receiving end of the base to the welding position, clamping and fixing the base, and then welding the receiving end of the base. The operation is relatively cumbersome, which greatly increases the welding time and greatly reduces the flexibility of switching the welding position of the base, thus reducing the welding efficiency.

A rotary motor 211 is mounted on the rotating end of the rotating frame 210. The output end of the rotary motor 211 is fixed to the rotating end of the rotating frame 210 via a coupling. A clamping seat 212 is rotatably mounted on the front side of the rotating frame 210. A rotary motor 214 is rotatably mounted on the rotating end of the clamping seat 212. The output end of the rotary motor 214 is fixed to the rotating end of the clamping seat 212 via a coupling. Two threaded rods 216 are mounted on the front end of the clamping seat 212 in a symmetrical arrangement. The threaded rods 216 are threadedly connected to the clamping seat 212. A clamping plate 215 is rotatably mounted on one end of the two threaded rods 216, which is close to each other. The clamping plate 215 is slidably connected to the clamping seat 212. A base 213 is provided between the two clamping plates 215. The end of the clamping plate 215 near the base 213 is made of rubber.

[0032] A wire feeding groove 217 is provided on the surface of the clamping base 212 near the rear side of the base 213. A rotating plate 218 is rotatably installed on the inner wall of the wire feeding groove 217 in a symmetrical arrangement. A torsion spring is connected between the rotating end of the rotating plate 218 and the inner wall of the wire feeding groove 217. When welding optical devices, the clamping mechanism is used to clamp and position the optical devices first. Then, the welding mechanism is used to weld the receiving end of the optical devices first. Then, the rotating structure is used to quickly rotate the transmitting end of the optical devices to the welding area. Then, the welding mechanism is used to weld the transmitting end of the optical devices. This reduces the tedious operation of repeatedly clamping and fixing the optical devices, and enables rapid switching between the transmitting and receiving ends of the optical devices, speeding up the welding time and improving the welding efficiency.

[0033] In this embodiment: the welding mechanism includes a support plate 301 set at the center of the base plate 100, a lifting plate 302 slidably arranged above the support plate 301, a lifting cylinder 303 between the lifting plate 302 and the support plate 301, a rotating disk 304 rotatably arranged at the end of the lifting plate 302 away from the support plate 301, an adjusting motor 305 is installed at the rotating end of the rotating disk 304, the output end of the adjusting motor 305 is fixed to the rotating end of the rotating disk 304 through a coupling, a connecting plate 306 is fixed at the end of the rotating disk 304 away from the support plate 301, and a welding head 307 is installed at the end of the connecting plate 306 close to the support plate 301.

[0034] Working principle: First, press the clamping mold 206 down onto the upper end of the front sliding seat 204, and use the clamping plate 208 to limit and fix the limiting plate 209. Then, insert the receiving head 207 into the clamping mold 206, and place the base 213 in front of the clamping seat 212. Rotate the two threaded rods 216 to drive the two clamping plates 215 to move close to the base 213, clamping and fixing the base 213. Then, start the moving motor 203 to drive the lead screw 202 to rotate, causing the front sliding seat 204 and the rear sliding seat 205 to move towards each other, driving the receiving end of the base 213 and the receiving head 207 to move closer to each other, so that the two fit together.

[0035] Then, the lifting cylinder 303 is driven to move the lifting plate 302 down, which in turn moves the welding head 307 down to the area to be welded. Then, the adjusting motor 305 is started to drive the rotating disk 304 and the connecting plate 306 to rotate, which in turn drives the welding head 307 to rotate. The welding head 307 is used to perform local spot welding on the receiving end of the base 213. Then, the rotating motor 211 is started to drive the rotating frame 210 to rotate, which drives the base 213 in the clamp to rotate, and drives the welding head 307 to perform circumferential spot welding on the receiving end of the base 213.

[0036] After the receiving end of the base 213 is welded, the base 213 is reset, and then the rotating motor 214 is started to drive the clamping seat 212 to rotate, thereby rotating the base 213 in the clamp and rotating the transmitting end of the base 213 to the area to be welded. Then, the transmitting end of the base 213 is spot welded in a ring using the above principle, thereby completing the laser welding operation between the receiving end and the transmitting end of the base 213. This reduces the tedious operation of repeatedly clamping and fixing the optical device, enables rapid switching between the transmitting end and the receiving end of the optical device, speeds up the welding time, and improves the welding efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
