Technical Field
The invention relates to product specification and size identification, in particular to a product specification and size identification mode.
Background
Along with the proposal of an intelligent factory, an assembly line of the electric equipment industry needs to improve the production efficiency and realize flexible production, and a customer can flexibly adjust a production work order. Because the product specification of the power industry is relatively large, the traditional assembly is difficult to be produced by products with various specifications, the mixed production among the products cannot be realized, and the utilization rate of a production line is low. Therefore, it is necessary to provide a product specification size identification method to solve the above problems.

The present invention is directed to provide a method for identifying the size of a product.
The technical scheme of the invention is realized as follows: a product specification size identification mode comprises the following steps:
the method comprises the following steps: firstly, loading six photoelectric switches on a mother vehicle, and respectively arranging transmitting ends and receiving ends of the six photoelectric switches at two sides of a track on the mother vehicle;
step two: then the product is placed on the sub-vehicle, the product is transported to the main vehicle through the sub-vehicle, when the product on the sub-vehicle passes through the photoelectric switch on the main vehicle, the synchronous circuit on the photoelectric switch is connected with the circuit, and the instant signal of the product passing is transmitted to the PLC;
step three: when the PLC receives an instantaneous signal that a product passes, extracting pulses generated when the sub-vehicle traveling wheel drives to rotate, and calculating the rotating speed of the motor by the PLC through high-speed counting;
step four: and then the PLC calculates the specification data of the products according to the photoelectric sequence of the products and the rotating speed of the motor, and distinguishes the products with different specifications.
In the above mode for identifying the specification, size and dimension of the product, the six photoelectric switches in the step one are averagely divided into two groups, and the two groups of six photoelectric switches are respectively arranged at the inlet and the outlet of the mother vehicle.
In the above method for identifying the specification and size of the product, the pulse width output by the motor in the third step is 2ms, and the output frequency (Hz) is 1/T.
In one of the above-mentioned product specification and size identification methods, the actual rotation speed (r/min) of the motor in step three is (output frequency/30) x 60.
