When sheet material 100 passes through the irradiation range of laser sensor 820, the reflection time of the optical path changes, thereby triggering laser sensor 820. The laser sensor 820 is electrically connected with an external control system, so that the detection result is fed back, and the control system is convenient to control the edge sealing assembly line more accurately.
