When guiding materials, the guide plate motor 333 drives the guide plate 334 to rotate, thereby allowing the materials to enter the photographing conveyor belt 34 sequentially; the slide plate 335 drives the guide plate motor 333 and the guide plate 334 on it to move.

[0032] In a preferred embodiment, refer to Figure 3 The double-layer belt visual inspection mechanism's photographic inspection component 36 includes a mounting bracket 361, a camera slide 362, a support rod 363, an inspection camera 364, and a light source 365.

[0034] In a preferred embodiment, refer to Figure 3 The double-layer belt visual inspection mechanism is also equipped with a working display 6 on the front side of the frame, and an alarm light 310 on the upper inspection component 3. The working display 6 is used to display the inspection process and status; the alarm light 310 responds when the equipment malfunctions, serving as a warning.

[0035] The working principle of the double-layer belt visual inspection mechanism of this utility model is as follows:

[0036] The operator first places the material to be inspected into the hopper 23 of the feeding elevator 2. The feeding elevator 2 then lifts the material to the highest point and drops it onto the transfer conveyor belt 24. The transfer conveyor belt 24 transports the material to the feeding belt 22 of the upper detection component 3. After entering the upper feeding belt, the material enters the lower feeding belt 22 through the distribution port 5. The feeding belt splits the material into two streams, which enter the sorting mechanism for sorting, so that the material is arranged in order. During the sorting process, excess material falls back into the hopper 23 of the feeding elevator 2. The neatly arranged material is guided to the photographing belt 34 by the guide plate component 33. The material passes through the photographing sensor 35 in sequence and triggers the photographing detection signal. The photographing detection component 36 takes a picture of the material for detection. According to the detection results, the qualified material is blown into the qualified discharge port 37, and the unqualified material automatically flows into the defective discharge port 38.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
