Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically to a PCB board reflow cooling buffer device. Background Technology

[0002] A PCB, also known as a printed circuit board, provides the electrical connections for electronic components. Based on the number of layers, PCBs can be classified as single-sided, double-sided, four-layer, six-layer, and other multi-layer PCBs. PCBs are typically first coated with adhesive and aged at high temperatures before being placed in a cooling buffer for further cooling. Since the PCB temperature is very high during this process, a cooling buffer device is required.

[0003] Currently, as disclosed in patent application number CN202310257141.0, this invention discloses a PCB board buffer machine, including a buffer mechanism for buffering PCB boards. The buffer mechanism includes several buffer boards, a lifting device for driving the buffer boards to move up and down, and a guide roller. When the guide roller rotates, it can drive the PCB board into the buffer area. It also includes a cooling mechanism for cooling the PCB board placed in the buffer area. The cooling mechanism includes a filter component, a diversion component, and a blowing component, which blows the diverted cold air onto the PCB board in the buffer area of ​​the buffer board to cool the PCB board.

[0004] However, in actual use, the above-mentioned patent has the following defects: the cooling effect on the PCB board is poor, and it is impossible to cool the PCB board quickly and evenly, thereby reducing the practicality of the device. Therefore, we propose a PCB board reflow cooling buffer device. Utility Model Content
