Description

Technical Field

[0001] The present invention relates to the technical field of 5G communication module circuit board assembly, and specifically to a connection positioning mechanism and a positioning method based on 5G communication module circuit board assembly. Background Art

[0002] During the assembly process of 5G communication module circuit boards, small processing plants install electronic components (such as connectors, diodes, resistors, capacitors, transistors, filters, sensors, crystal oscillators, etc.) on the top of the 5G communication module circuit boards and fix them by soldering:

[0003] Generally, the electronic components are manually placed inside the corresponding mounting holes reserved on the 5G communication module circuit board. Then, the 5G communication module circuit board is turned over. One hand holds down the electronic component to make it close to the 5G communication module circuit board. The other hand uses a soldering tool to solder the electronic component to the 5G communication module circuit board. After soldering one of the electronic components using the above method, the remaining electronic components are soldered (repeat the above soldering operation).

[0004] This welding method cannot place all electronic components on the 5G communication module circuit board for pre-fixation at the same time during the welding process, resulting in low welding efficiency. In addition, the existing 5G communication module circuit board welding station installs a smoke extraction device on one side of the station to absorb the smoke generated during the welding process. During the welding process, if the soldering position is far away from the suction port of the smoke extraction device, smoke will enter the air and affect the working environment. Therefore, in order to solve the above problems, a connection positioning mechanism based on the assembly of a 5G communication module circuit board and a positioning method thereof are proposed. Summary of the Invention

In addition, the existing 5G communication module circuit board welding station installs a smoking device on one side of the station to absorb the smoke generated during the welding process.
