The weighing platform 21 weighs the settlement commodity, and the weight signal is transmitted to the control mechanism. The camera collects the image of the settlement commodity, and the image signal is transmitted to the control mechanism. The control mechanism will call out the weight of the commodity corresponding to the image according to the collected image signal, and compare it with the actually received weight signal. For the identification of the settlement commodity, the control mechanism calls out the price of the commodity, and the settlement commodity is pushed onto the transport platform 30 . If the weight of the product transferred out is not equal to the weight collected by the weighing platform 21, then the gate 50 moves to expose the commodity inlet 11, as shown in Figure 5, the consumer needs to sort out the settlement products, and then put them on the weighing platform 21 again , for identification.

The commodity identification mechanism 20 of the commodity automatic settlement machine provided by the present invention can simultaneously scan the image of the commodity and weigh the commodity. If a consumer hides another commodity under the commodity when paying for a certain commodity, although the camera cannot collect the image signal of the hidden commodity, the weighing table 21 weighs the weight of the settled commodity plus the hidden commodity, so The settlement commodity weight transferred by the control agency is definitely not equal to the weight collected by the weighing platform 21, the settlement commodity will not be pushed to the transport platform 30, and the consumer can only continue to settle after taking out the hidden commodity.
