In the conveying process, friction and sliding are not easy to generate between the PCB small plate 10 and the flat-plate type horizontal plate-collecting conveying belt section 210, the PCB small plate 10 is not damaged, and the product quality is ensured. Moreover, the inclined board collecting conveyor belt section 220 is obliquely arranged behind the horizontal board collecting conveyor belt section 210, so that the small PCB 10 can be automatically adjusted to be in an inclined state after being conveyed to the inclined board collecting conveyor belt section 220, and the board can be automatically collected on the board collecting tooling mechanism 500 under the action of the board collecting auxiliary mechanism 400.
