[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1-3 As shown, the carrier CCD detection device includes a detection mechanism 01 and a dust removal mechanism 02;

[0026] The detection mechanism 01 includes an upper light source 11, a grating detection head 12, a material strip base 13, and a lower light source 14, which are arranged in sequence from top to bottom. The material strip base 13 has a lower through hole in the middle for light from the lower light source 14 to pass through. The upper edge of the material strip base 13 is provided with a material guide trough 15 that is consistent with the transmission direction of the material strip 08. A material strip pressure plate 16 is provided above the material guide trough 15. The material strip pressure plate 16 has an upper through hole in the middle for light from the upper light source 11 to pass through.

[0027] The dust removal mechanism 02 is arranged before the conveying direction of the material belt 08 of the detection mechanism 01, and includes a dust blowing box with an opening for the material belt 08 to pass through;

[0028] It also includes a camera 03 that is arranged corresponding to the position of the detection mechanism 01.

The side door 63 is provided with a slot consistent with the transmission direction of the material belt 08. The operation keyboard 05 is arranged on the front door 64 to form a semi-enclosed detection space to prevent the dust in the workshop from contaminating the detection mechanism 01, and can also protect the detection mechanism 01 to prevent bumps.
