Description

Technical Field

[0001] It relates to the technical field of buffer machines, and particularly to a rotary automatic conveying buffer machine. Background Art

[0002] When processing the welding of a PCB board, the welding area needs to be heated to a certain temperature for preheating, then welding materials (such as tin) are added to the welding area, and a welding tool is used for welding to fix electronic components on the PCB board. After welding, the welding area needs to be cooled for a period of time to avoid overheating of the welding area and affecting the next process of the PCB board.

[0003] According to Chinese Patent CN213028726U, a PCB circuit board buffer machine is disclosed. The device includes a frame, a pair of conveying tracks, a buffer box, and a buffer lifting mechanism. The buffer lifting mechanism includes a pair of buffer lifting plates and a number of buffer placement tracks. The pair of buffer lifting plates are placed in the buffer box, and the buffer placement tracks are arranged on the buffer lifting plates. The buffer lifting plates automatically lift and lower a certain distance after caching one to continue caching, so as to meet the requirements of production use. However, this device uses the buffer box as a medium to hold the PCB circuit board and adopts a vertical lifting method. When subsequent processing is required, manual or other equipment is still needed for handling, resulting in low efficiency and large space occupation.

[0004] Therefore, it is necessary to develop a rotary automatic conveying buffer machine to solve the above problems. Summary of the Invention

The rotating motor 41 drives the material supporting plate 43 to move around the rotating shaft 411 through the transmission member 42. Another material supporting plate 43 moves to the position corresponding to the entrance 122 and repeats the previous process. The telescopic pipe 4223 at the end of the telescopic transmission arm 422 moves along the track 5, and the material supporting plate 43 loaded with the PCB board moves along the track 5 accordingly. When moving to the exit 123, the PCB board is cooled by the cooling member 2 and left for a long time to complete the cooling. The lifting member 33 drives the suction cup 342 to suck the PCB board and transport it to the conveyor belt.

[0038] The present invention is a rotary automatic conveying buffer machine, which has the characteristics of high efficiency and small occupied space. The rotating motor drives the material supporting plate to move around the rotating shaft through the transmission member, so that the material supporting plate loaded with the PCB board moves along the track in sequence.
