[0037] Refer to Figures 1 to 3, an embodiment of the utility model provides a cutting machine for slitting LED light strips, which includes a frame 100, on which a workbench 110 is provided. The workbench 110 is provided with a detection area 120, and the detection area 120 is provided with a plurality of light-transmitting holes 121. The light-transmitting holes 121 are arranged in a matrix distribution. A detection channel 130 for the light strip to pass through is formed between each column of light-transmitting holes 121.
