Problems solved by technology

[0003] Most of the PCB board welding can be completed by welding equipment, but there are also some welding components that are not convenient to complete on the welding equipment, and still need to be welded by hand. The existing welding workbench has a single structure and cannot complete the welding. The PCB board needs to be cooled naturally, and the blanking needs to be completed after natural cooling, resulting in prolonged non-processing time and low processing efficiency, making it difficult to meet the needs of modern PCB board production.

Abstract

The invention discloses a PCB welding table based on an independent cooling technology. The PCB welding table comprises a table frame; the top end of the table frame is connected with an overturning cavity in a communicating mode; a welding table plate is arranged in the overturning cavity; the welding table plate is rotationally connected to the inner cavity wall of the overturning cavity throughan overturning shaft; side supporting cavities are symmetrically formed in the left side end and the right side end of the table frame; supporting columns are arranged in the side supporting cavities; the supporting columns are rotationally connected to the side supporting cavities through rotating shafts; first protective nets, air cooling fans and pneumatic cylinders are sequentially arranged in inner cavities of air cooling holes from bottom to top; and supporting plate assemblies matched with the welding table plate are fixedly connected to the top ends of pneumatic rods on the pneumaticcylinders. External air is dragged by the air cooling fans to enter the air cooling holes and blows upwards along the air cooling holes, the rising airflow flows to the bottom end of the welding tableplate under the action of a flow guide cavity and obliquely blows the PCB on the welding table plate, thus the PCB can be rapidly cooled, the cooling time of the PCB can be greatly shortened, the non-machining time can be greatly shortened, and the machining efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of welding stations, in particular to a PCB board welding station based on independent cooling technology. Background technique [0002] PCB, or printed circuit board, referred to as printed board, is one of the important components of the electronics industry. Almost every kind of electronic equipment, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between various components, printed circuit boards must be used. plate. The printed circuit board is composed of an insulating base plate, connecting wires and pads for assembling and welding electronic components, and has the dual functions of a conductive line and an insulating base plate. [0003] Most of the PCB board welding can be completed by welding equipme...
