Description

Technical Field

[0001] The utility model relates to the technical field of laser soldering, in particular to a laser soldering double wire feeding and surrounding control device. Background Technique

[0002] Existing soldering processes all heat the soldering iron head and then send solder to the soldering iron head through a single feeding device for ordinary soldering; however, this soldering method has great limitations. For example, when soldering products such as socket type solder joints over 5mm and CABLE wires on the surface of a PCB, due to the single soldering method, feeding angle, and the activity of the solder wire itself, when soldering larger pads, problems such as insufficient soldering, solder bridging, and incomplete tin infiltration are likely to occur, thus affecting the soldering effect, resulting in poor contact, and even components may fall off.

[0003] Therefore, the utility model provides a laser soldering double wire feeding and surrounding control device. Summary of the Utility Model

The utility model can feed two solder wires simultaneously, send the solder wires to the periphery of the soldering iron, thereby expanding the feeding angle and preventing problems such as insufficient soldering. Moreover, the feeding length of the two solder wires is the same each time, ensuring the soldering effect; the height of the support frame can also be adjusted to facilitate feeding.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A laser soldering double wire feeding and surrounding control device includes a fixed frame. A support frame is slidably fitted on one side of the fixed frame. Two driving rollers and two auxiliary rollers are rotatably fitted on the support frame. A first guide pipe, a second guide pipe, and a third guide pipe are fixed on the support frame. Two through grooves are provided in each of the first guide pipe, the second guide pipe, and the third guide pipe. One end of the third guide pipe is fixed with a connector, and two distribution pipes are fixed on the connector. A connecting frame is fixed on the support frame, and two solder wire rollers are rotatably fitted on one side of the connecting frame.

[0006] Further, a cylinder is fixed on the fixed frame, the output end of the cylinder is fixedly connected with the support frame, and a slider is fixed on the support frame and slidably connected with the fixed frame.

[0007] Further, a motor is fixed on the support frame, a first gear is fixed at the output end of the motor, a second gear is fixed on the driving roller, and the second gear meshes with the first gear.

[0008] Further, the first guide pipe, the second guide pipe, and the third guide pipe are all located between the driving roller and the auxiliary roller.

[0009] Further, one side of the connecting frame is fixed with a mounting shaft, and the mounting shaft is rotatably connected to the solder wire roller.

[0010] Further, a partition is fixed on the mounting shaft. The partition is located between the two solder wire rollers, and solder wire is wound around the circumferential side of the solder wire roller.

[0011] Further, the third material guide pipe, the connecting head and the material distribution pipe are communicated with each other. The first material guide pipe, the second material guide pipe, the third material guide pipe, the connecting head and the material distribution pipe all correspond to the solder wire.

[0012] Further, a soldering iron is fixed on the connecting head, and the material distribution pipe is located on the circumferential side of the soldering iron.

By installing a material distribution pipe on the connecting head, the solder wire can be sent to the circumferential side of the soldering iron, so as to expand the feeding angle and prevent situations such as lack of soldering. Moreover, the feeding length of the two solder wires is the same each time, ensuring the soldering effect. By slidingly connecting the fixing frame and the support frame, the height of the support frame can be adjusted, thus facilitating the feeding. Description of the Drawings
