Auxiliary welding device for components of PCBA

Abstract

The invention discloses an auxiliary welding device for components of a PCBA. The auxiliary welding device for the components of the PCBA is used for positioning the components of the PCBA on a PCB and comprises a base, a supporting base installed on the base, a welding positioning block, an insertion positioning block, a PCB positioning plate and an upper fixing cover plate. The welding positioning block and the insertion positioning block are installed on the supporting base and are oppositely arranged in a spaced mode, and the supporting base is arranged between the welding positioning block and the insertion positioning block. The PCB positioning plate is connected with the supporting base in a rotary mode through a rotary shaft, and a hollowed-out part used for exposing the welding portion of the PCB is arranged on the PCB. The upper fixing cover plate is movably connected with the PCB positioning plate. A positioning structure used for positioning the components of the PCBA is arranged on the surface, opposite to the PCB positioning plate, of the upper fixing cover plate. The upper fixing cover plate rotates around the rotary shaft along with the PCB positioning plate and can be selectively overturned onto one of the welding positioning block and the insertion positioning block. The auxiliary welding device for the components of the PCBA has the advantages that the welding quality of the components of the PCBA can be improved, welding efficiency is high, the welding cost can be lowered and labor intensity can be relieved.

Description

【Technical field】 [0001] The invention relates to a welding auxiliary device, in particular to a PCBA component welding auxiliary device. 【Background technique】 [0002] PCBA (Printed Circuit Board Assembly), that is, the PCB board is subjected to surface mount technology (SMT, Surface Mounted Technology) upper parts, and then through the entire process of dual in-line packaging technology (DIP, Dual In-line Package) plug-ins, Abbreviated as PCBA. [0003] When soldering the components on the PCBA, the wave furnace welding process is usually used. For small batches and multiple varieties, due to the high investment cost of the wave furnace welding equipment, the usual method is to fix the PCBA and insert the components. , Turn over the PCBA and solder the components with your hands or objects, and the PCBA is usually fixed horizontally. When there are more than two components, it cannot be kept vertically flat on the PCBA. If the soldering process is loose, the components w...

[0003] When soldering the components on the PCBA, the wave furnace welding process is usually used. For small batches and multiple varieties, due to the high investment cost of the wave furnace welding equipment, the usual method is to fix the PCBA and insert the components. , Turn over the PCBA and solder the components with your hands or objects, and the PCBA is usually fixed horizontally. When there are more than two components, it cannot be kept vertically flat on the PCBA. If the soldering process is loose, the components will slip off. Therefore, it is not necessary Easy to solder a large number of components
