Technical Field

The invention belongs to the technical field of hot pressing heads, and particularly relates to a hot pressing head control system based on a wireless radio frequency tag.

Background

The radio frequency identification tag technology is widely used in the field of control of the birthday process. The radio frequency identification tag comprises a chip, an aluminum foil antenna and a carrier substrate layer, wherein the aluminum foil antenna is attached to the carrier substrate layer, pins of the chip and pins of the aluminum foil antenna are connected through conductive adhesive in a hot-pressing mode, tag information is stored in the chip, and a reading device can read information in the chip in a non-contact mode.

In the actual use process, only part of the production of the wireless radio frequency tag needs to be put into operation; the other part of the hot-pressing head needs to be idle; the hot-pressing head which is put into use needs to be heated electrically, and the hot-pressing head which is not put into use is not electrified. Before production, an operator needs to record and select the number of the hot pressing heads to be used, and provides power for the coils of the corresponding relays one by one, after the coils of the relays are electrified, the contacts of the relays are closed, the corresponding heaters are connected with the power supply of the heaters, and the hot pressing heads are electrified and heated. If the coil of the relay is in a power-off state, the contact of the relay is still in an off state, and the corresponding heater cannot heat. Because the number of the hot pressing heads is large, the hot pressing heads are easy to be confused, and errors are easy to occur when the serial numbers of the hot pressing heads are recorded or the relays are switched on. If the hot-pressing heads which need to be put into use are not heated electrically, the hot-pressing heads generate poor products.

The invention provides a hot-pressing head control system based on a wireless radio frequency tag, which connects a hot-pressing head to be heated with a common electrode plate and controls the on-off of a corresponding heater through a PLC controller, thereby avoiding errors caused by manual control of power-on or power-off of a corresponding relay, facilitating control and improving the control efficiency of the hot-pressing head.
