Description

Technical Field

[0001] The invention belongs to the field of welding, in particular to a positioning welding device for producing electronic equipment. Background Art

[0002] The basic components of electronic equipment include power supply, circuit, functional components and peripherals. In the production of electronic equipment, electronic components need to be soldered to the circuit board to form a functionally complete electronic module or system. In the circuit board soldering process, it is necessary to create the layout and wiring of the circuit board, and it is necessary to consider the reasonable placement of components, planning of circuit routing and other factors. Through processes such as wave soldering or reflow soldering, the components and the circuit board are firmly soldered together.

[0003] The automatic welding process of circuit boards adopts fixed-point welding technology or continuous welding technology. Fixed-point welding uses professional robots for accurate welding processing. Continuous welding is a common flow welding and continuous welding in production workshops.

During the welding process, its heat-affected area is large, which may cause the temperature around the welding area to rise. If the circuit board is collected directly after welding, the surface temperature of the circuit board is too high. On the one hand, it will scald the staff.

The circuit board is fixed by using the retaining mechanism 8 and the end fixing block 9, and the positioning cylinder surface 302 rotated to the top of the top mainboard positioning cylinder 3 is soldered to weld the circuit board on the positioning cylinder surface 302.
