[0030] Please see Figure 3 The first storage bin 2 also includes a driving member 25, which is a motor or a cylinder having a driving shaft 251.

In another embodiment, the number of driving members 25 can be a pair, which respectively drive a pair of splints 23 to move relative to each other or in the opposite direction.

[0031] Please see Figure 3 , a material storage part 26 is provided on one side opposite to the splint 23, and the material storage part 26 includes a driving wheel 261, a passive wheel 262, and a transmission belt 263 surrounding the driving wheel 261 and the passive wheel 262. The driving wheel 261 is driven by a driving device such as a motor, and the passive wheel 262 is on the same horizontal line as the driving wheel 261. The transmission belt 263 is a closed loop. The driving wheel 261 drives the passive wheel 262 to rotate synchronously through the transmission belt 263. The number of material storage parts 26 is changed according to demand, and is distributed vertically downward from the top of the splint 23 to its bottom.

[0032] Please see Figure 4 A lifting device 6 is provided below the first material storage bin 2, and the lifting device 6 includes a lifting drive member 61 and a lifting rod 62.

[0036] The utility model is a circuit board cooling buffer device. When in use, the circuit board is conveyed to the first storage bin 2 through other material conveying devices, and the storage part 26 at the bottom of the first storage bin 2 receives the circuit board. The transmission belt 263 of the storage part 26 lifts the circuit board and drives the circuit board to move into the first storage bin 2. After moving into place, the storage part 26 stops driving the circuit board, and the cooling part 5 blows air to the circuit board located in the first storage bin 2 to cool the circuit board.
