A vision detection mechanism is provided on the conveyor belt base. The vision detection mechanism includes a loading rack, a camera module, and a detection host. The loading rack includes a vertical frame body bridged on the conveyor belt base. Light-shielding plates are respectively provided on the outer peripheral surface of the vertical frame body. A gap for the product to pass through is left between the light-shielding plates and the conveyor belt of the conveyor belt base. The camera module is arranged on the top frame of the vertical frame body, and the detection host is arranged on the bottom support frame of the conveyor belt base. This detection device can achieve docking with the automatic production line, eliminating the need for manual transfer, and at the same time meeting the requirements of flow-through detection, greatly improving the detection efficiency and reducing the labor cost.
