Description

Welding device for processing electronic components

Technical Field

The invention relates to the technical field of electronic component welding, in particular to a welding device for processing electronic components.

Background Art

Common electronic component welding is divided into pin component welding and chip component welding. When performing pin component welding, the pins of the components need to be inserted into the required positions on the circuit board. The pins can be snapped into the reserved holes of the circuit board. The circuit board is then flipped over to solder the pins. Usually, the circuit board needs to be flipped manually, which is a cumbersome operation.

A Chinese invention patent with publication number CN118342062A discloses an electronic component welding device, including a workbench, a pretreatment device, a placement table, a flipping device and a support plate are fixedly connected to the upper surface of the workbench, a first electric push rod is fixedly connected to the bottom of the workbench, the top of the first electric push rod is fixedly connected to the support table, the outer surface of the workbench is fixedly connected to the support device and the electric control box, a fixing device is arranged inside the bent top plate, the flipping device includes a fixing seat, the bottom of the fixing seat is fixedly connected to the upper surface of the workbench, the outer surface of the fixing seat is fixedly connected to the first telescopic rod, the outer surface of the mounting seat is fixedly connected to the driving motor, the output shaft of the driving motor is fixedly connected to the clamping mechanism, the circuit board can be clamped and fixed by the flipping device and the clamping mechanism to prevent the circuit board from moving and affecting the welding effect, and the circuit board can also be automatically flipped when welding pin components.

However, the above patent still has the following deficiencies in actual use: the patent clamps the circuit board by a clamping mechanism, and automatically flips the circuit board by a flipping device when soldering pin components, but the pins of the pin components are engaged in the reserved holes of the circuit board, and this engaging fixing force is unstable. After the pin components are gradually inverted due to flipping, the pin components lose the supporting force of the circuit board, and the pins can easily fall out of the reserved holes due to the pin components' own gravity, which can cause the pin components to be misplaced or even fall off, thereby affecting the soldering quality of the pin components.
