[0003] In the prior art, when manually welding a small batch of circuit boards, the circuit boards are placed in a mold and then clamped and fixed, and the connection between electronic components and the PCB is fixed by melting solder. However, since the mold can only weld a single circuit board, although the number of circuit boards is small, it still takes time, and the welding efficiency is low. Moreover, during the welding process, problems such as loosening and dropping of electronic components will occur, resulting in poor welding effect, and secondary manual welding is required, wasting time.
[0004] Therefore, it is necessary to provide a new flexible board welding tooling for optoelectronic devices to solve the above problems. Summary of the Utility Model

[0027] The following specifically describes the specific settings and functions of its clamping device 3 and rotating device 4.
[0028] Refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in , in this embodiment: The clamping device 3 includes two auxiliary plates 306. Both sides of the auxiliary plate 306 are fixedly connected to the inner side of the rotating frame 2. The surface of the auxiliary plate 306 is fixedly connected with a fixing plate 301. An auxiliary groove 303 is formed on the surface of the fixing plate 301. The inner wall of the auxiliary groove 303 abuts against a circuit board 6. The surface of the auxiliary plate 306 is fixedly connected with a rotating frame 307. A rotating plate 302 is rotatably connected to the inner wall of the rotating frame 307. Both ends of the surface of the rotating plate 302 are fixedly connected with fixing blocks 308. The bottom surface of the fixing block 308 is fixedly connected with a telescopic rod 309. A first spring 312 is slidably connected to the arc surface of the telescopic rod 309. One end of the telescopic rod 309 away from the fixing block 308 is rotatably connected to a clamping block 310. Both ends of the first spring 312 are fixedly connected with the fixing block 308 and the clamping block 310 respectively. A limiting block 313 is fixedly connected to the surface of the fixing plate 301 corresponding to the position of the clamping block 310. A clamping groove 314 is formed on the bottom surface of the limiting block 313. The inner wall of the clamping groove 314 abuts against the upper surface of the clamping block 310. Before welding the circuit board 6, first place the circuit board 6 in the auxiliary groove 303, rotate the rotating plate 302 towards the fixing plate 301, and then pull down the clamping block 310 to drive the telescopic rod 309 to extend and the first spring 312 to extend. During this process, the first spring 312 is in a stretched state until the clamping block 310 is pulled below the fixing plate 301, and then rotate the clamping block 310 so that its position corresponds to the clamping groove 314. Finally, release the hand. At this time, under the action of the first spring 312, the clamping block 310 is pulled upward until it contacts the clamping groove 314, achieving the fixation of multiple circuit boards 6, improving the welding efficiency, and preventing the circuit board 6 from shaking during welding, resulting in poor welding effect. A first pull ring 311 is fixedly connected to the bottom surface of the clamping block 310. The cross-section of the first pull ring 311 is circular, which is convenient for pulling and rotating the clamping block 310, making the operation more convenient. A pull rod 304 is fixedly connected to the surface of the rotating plate 302. The cross-section of the pull rod 304 is "U" shaped, which is convenient for rotating the rotating plate 302, making the operation more convenient. An extrusion plate 305 is fixedly connected to the surface of the rotating plate 302. The extrusion plate 305 is an elastic plate and a high-temperature resistant plate, which enhances the extrusion force on components such as capacitors and resistors on the circuit board 6, thereby strengthening the fixing effect and facilitating the welding of the circuit board 6.
[0029] Refer to Figure 7 and Figure 8As shown in the figure, in this embodiment: The rotating device 4 includes a rotating ring 41. The inner wall of the rotating ring 41 is fixedly connected to the arc surface of the rotating shaft 5. A plurality of limiting grooves 47 are formed on the surface of the rotating ring 41. At the position corresponding to the limiting grooves 47 on the surface of the support frame 1, an auxiliary block 43 is fixedly connected. A limiting rod 44 is slidably connected to the inner wall of the auxiliary block 43. One end of the limiting rod 44 close to the rotating ring 41 abuts against the inner wall of the limiting groove 47. A second spring 45 is slidably connected to the arc surface of the limiting rod 44. The two ends of the second spring 45 are respectively fixedly connected to the auxiliary block 43 and the limiting rod 44. After the circuit board 6 is fixed, first pull out the limiting rod 44 from the limiting groove 47. In this process, the second spring 45 is in a stretched state. Then rotate the rotating ring 41 to expose the bottom surface of the circuit board 6. Then release the hand. At this time, under the action of the second spring 45, the limiting rod 44 is driven to enter the limiting groove 47 to fix the rotating ring 41, achieving the convenience of welding the circuit board 6 and improving the welding efficiency. The other end of the limiting rod 44 is fixedly connected to a second pull ring 46. The cross section of the second pull ring 46 is circular, which is convenient for pulling the limiting rod 44 and is easy to operate. An anti-slip ring 42 is fixedly connected to the arc surface of the rotating ring 41. The anti-slip ring 42 is an elastic ring, which increases the friction with the palm and prevents hand slipping.
[0030] The working principle of a soft board welding tool for optoelectronic devices provided by the present invention is as follows. Before welding the circuit board 6, cover the pull rod 304 with the hand and move it upward. The pull rod 304 drives the rotating plate 302 to rotate. Place the circuit board 6 in the auxiliary groove 303. Then cover the pull rod 304 and move it towards the fixed plate 301. The pull rod 304 drives the rotating plate 302 to rotate again, so that the pressing plate 305 on the surface of the fixed plate 301 contacts the capacitors and resistors on the surface of the circuit board 6. Then pull down the first pull ring 311. The first pull ring 311 drives the clamping block 310. The clamping block 310 drives the telescopic rod 309 to stretch and the first spring 312 to stretch. In this process, the first spring 312 is in a stretched state until the clamping block 310 is pulled below the fixed plate 301. Then rotate the clamping block 310 so that its position corresponds to the clamping groove 314. Finally, release the hand. At this time, under the action of the first spring 312, the clamping block 310 is pulled upward until it contacts the clamping groove 314. By providing the clamping device 3, multiple circuit boards 6 can be fixed, the welding efficiency can be improved, and the problem that the circuit board 6 shakes during welding, resulting in poor welding effect, can be prevented.
[0031] After the circuit board 6 is fixed, first pull the second pull ring 46. The second pull ring 46 drives the limit rod 44 to be pulled out of the limit groove 47. During this process, the second spring 45 is in a stretched state. Then cover the anti-slip ring 42 and rotate the rotating ring 41 to expose the bottom surface of the circuit board 6 upward. Then release the hand. At this time, under the action of the second spring 45, the limit rod 44 is driven to enter the limit groove 47 to fix the rotating ring 41. By providing the rotating device 4, it is convenient to expose the bottom surface of the circuit board 6 upward, improving the welding efficiency.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
