Technical Field

[0001] The present invention mainly relates to the technical field of electronic components, and specifically to a PCBA board disassembly tool and method for an inverter assembly of a new energy vehicle, and a working method thereof. Background Art

[0002] PCBA is the entire process of a PCB blank board through SMT mounting or DIP plug-in, referred to as PCBA. This is a commonly used writing method in China.

The fixing block can be flexibly and adaptively adjusted according to the edge shape of the PCBA board under the elastic force of the spring. The elastic force of the spring will produce corresponding deformation according to the degree of pressure applied by the PCBA board, thereby pushing the fixing block to fit closely to the edge of the PCBA board, so that the fixing block can perfectly adapt to PCBA boards of different shapes and sizes, and achieve accurate fixation of them. Whether it is a rectangular, square or irregular PCBA board, it can be fixed to ensure that there will be no deviation during the disassembly process, thereby improving work efficiency and equipment reliability; Through the crowbar mechanism and the lever principle, the PCBA board can be quickly separated from the substrate with little force, which greatly improves efficiency and eliminates the need for manual separation by staff. By using the vacuum mechanism, the softened adhesive particles can be effectively cleaned during the heating separation process, thereby ensuring the cleanliness of the PCBA board surface, improving work efficiency and facilitating subsequent work. Through the special extraction mechanism, the PCBA board can be automatically adsorbed and transported, and safely stored in the designated location without the need for manual picking and transport by staff, which greatly reduces labor costs and also reduces the risk of damage caused by human operational errors. The PCBA board can be heated by designing a heating plate, a temperature sensor, and a temperature controller to soften the connection materials (such as thermal grease and solder paste) between the PCBA board and the base and other components. The temperature sensor can detect and feedback to the temperature controller in real time to meet the heating requirements of different types of adhesives or welding materials. This not only effectively avoids the dilemma of insufficient heating that causes the connection materials to be insufficiently softened and difficult to disassemble, but also prevents the risk of thermal damage to the PCBA board or other components due to excessive heating, creating extremely favorable conditions for subsequent smooth disassembly work. At the same time, it also replaces the manual use of solder pens to soften certain parts on the PCBA board, greatly reducing the workload. The application of automated equipment improves efficiency.
