The cache component 200 is arranged across the cache On the conveyor line 120, the cache component 200 has a cache end that moves in the vertical direction and can pass through the cache conveyor line 120. The cache end has a plurality of cache gaps arranged in sequence in the vertical direction and extending along the length direction of the cache conveyor belt. The diversion component 300 includes a lifting member 310 and a diversion conveyor line 320. The lifting member 310 is installed on the first output conveyor line 130. The output end of the lifting member 310 is connected to the diversion conveyor line 320, and is used to drive the conveying surface of the diversion conveyor line 320 to move to a position below the first output conveyor line 130 or to a position aligned with the second output conveyor line 140.

[0025] During implementation, the circuit boards flow through the feed conveyor line 110, the cache conveyor line 120 and the first output conveyor line 130 in sequence. In order to avoid congestion when conveying the circuit boards, a cache component 200 is set up, and its movement in the vertical direction can continuously collect and store the circuit boards conveyed by the feed conveyor line 110. By controlling the height of the cache component 200, the size of the cache space can be controlled to meet the cache requirements of the conveyor line. At the same time, a diversion component 300 is also provided. When the diversion conveyor line 320 is located below the first output conveyor line 130, the circuit boards flow out from the first output conveyor line 130. When the diversion conveyor line 320 is located in a position aligned with the second output conveyor line 140, the circuit boards on the first output conveyor line 130 are lifted up and flow out from the second output conveyor line 140, thereby realizing the diversion function.

At the same time, a diversion component 300 is also provided. When the diversion conveyor line 320 is located below the first output conveyor line 130, the circuit boards flow out from the first output conveyor line 130.
