Description

Technical Field

[0001] This utility model relates to the field of circuit board welding technology, and in particular to a circuit board patch welding mechanism. Background Technology

[0002] Circuit boards make circuits miniaturized and more intuitive, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can also be called printed circuit boards or printed circuit boards. The birth and development of FPC and PCB gave rise to the new product of rigid-flex boards. Therefore, rigid-flex boards are flexible circuit boards and rigid circuit boards, which are combined together according to relevant process requirements through processes such as lamination to form a circuit board with the characteristics of both FPC and PCB. In the process of assembling circuit boards, after electronic components such as resistors and capacitors are mounted on the circuit board, the solder needs to be melted at high temperature, and after cooling, the components are soldered to the corresponding positions on the circuit board.

[0003] A patent with publication number CN210112419U discloses a circuit board fixed-point welding device. This patent includes a base plate, a clamp, a placement slot, a circuit board, an upper plate, a hydraulic rod, a control board, a wire slot, a bus, a welding plate, clamping holes, a magnetic ring, a positioning tube, a heating ring, a wire feed chamber, a drive wheel, a driven wheel, a motor, and welding wire. By setting a clamp on the base plate, the circuit board is clamped in place, preventing displacement during welding and affecting welding quality. The welding plate has multiple clamping holes, each corresponding to a welding point. A positioning device is installed within each clamping hole. The positioning tube has a heating ring at one end. The heating ring melts the welding wire inside the positioning tube and spots-welds the melted wire to the designated position, completing the positioning welding. Positioning connections are achieved by setting corresponding magnetic rings on the welding plate and the positioning tube, making installation and disassembly convenient and allowing for precise installation according to actual needs. The wire feeding chamber contains a drive wheel and a driven wheel, which engage the welding wire. A motor is connected to one side of the drive wheel, and the motor is controlled by a control board to quantitatively feed the welding wire for optimal welding results. However, this patent still has the following problems:

[0004] The aforementioned circuit board welding device cannot adjust the clamping distance of the circuit board during use, making it inconvenient to clamp circuit boards of different widths. This results in a limited application of the circuit board surface mount welding machine. Furthermore, the welding machine can only be adjusted in height during welding, not in position, which further hinders its welding application.
