The control panel 211 can be used to adjust or activate the detection camera 204 and the adjuster 207. The garment to be inspected is placed on the light-transmitting plate 208. The light of the color-changing light plate 206 is adjusted according to the color of the garment through the control panel 211. At the same time, the inspection camera 204 is activated through the control panel 211 for rapid inspection.

[0029] like Figure 4 As shown, the sorting component 3 includes two partitions 301 fixedly connected to the top of the placement plate 205 to prevent garments from falling. An air outlet frame 302 is disposed between the two partitions 301, and a fan 303 is bolted inside the air outlet frame 302. The fan 303 is electrically connected to the control panel 211. A guide plate 304 is disposed on one side of the air outlet frame 302, and a defect frame 305 is disposed on one side of the frame 1. The fan 303 is activated via the control panel 211 to blow defective garments into the defect frame 305. When a defective garment is detected, the control panel 211 activates the fan 303, which blows the defective garment into the defect frame 305 via the guide plate 304 for centralized processing.

[0030] like Figure 3 As shown, a fill light plate 4 is fitted around the detection camera 204, and the fill light plate 4 is electrically connected to the control panel 211.
