Detailed Description
The present invention will now be described in further detail with reference to specific examples, which are intended to be illustrative, but not limiting, of the invention.
As shown in fig. 1, the anti-counterfeit label electrolytic hot stamping device of the invention comprises a positive electrode 1, a negative electrode clamping plate 2, a steady flow control device 3 and a power supply 4, wherein the steady flow control device 3 ensures constant current in the electrolytic process, does not generate noise and ensures hot stamping efficiency; the positive electrode 1 is connected with the positive output end of the current stabilization control device 3, and the negative electrode clamping plate 2 is connected with the negative output end of the current stabilization control device 3; and the positive electrode of the power supply at the positive electrode output end of the current stabilization control device 3 is connected with the positive electrode of the power supply, and the negative electrode output end of the current stabilization control device is connected with the negative electrode of the power supply.
As shown in fig. 2, the steady flow control device 3 includes a main rectifier cabinet 31, a pulse transformer 32, a single chip microcomputer 33, a first amplifying circuit 34, a dc sensor 35 and a standard circuit 36; the direct current sensor 35 is connected with the input end of the first amplifying circuit 34, the output end of the first amplifying circuit 34 is connected with the single chip microcomputer 33, the single chip microcomputer 33 is connected with the input end of the pulse transformer 32, the output end of the pulse transformer 32 is connected with the input end of the rectification main cabinet 31, the positive output end of the rectification main cabinet 31 is respectively connected with the positive electrode 1 and the power supply positive electrode, and the negative output end of the rectification main cabinet 31 is respectively connected with the negative electrode clamping plate 2 and the power supply negative electrode; the output end of the standard circuit 36 is connected with the singlechip 33.
When the anti-counterfeit label is used, a metal conductive workpiece to be hot stamped is clamped on the negative electrode clamping plate 2 to be fixed, the transfer film printed with the anti-counterfeit label is laid at a preset position of the metal conductive workpiece to be hot stamped, the positive electrode 1 is close to the transfer film, electrolyte is dripped on the transfer film to be electrolyzed, and therefore the anti-counterfeit label on the transfer film is peeled off to the metal conductive workpiece. The positive electrode 1 cannot be tightly attached to the transfer film because the close attachment is likely to cause the transfer film to be burnt.
When the current of the power supply flows through the positive electrode 1 and the negative electrode clamping plate 2, the positive electrode 1 and the negative electrode clamping plate 2 generate corresponding direct current feedback signals, and the direct current feedback signals exist in the form of magnetic fields. The direct current sensor 35 collects direct current feedback signals of the positive electrode 1 and the negative electrode clamping plate 2 and sends the collected direct current feedback signals to the first amplifying circuit 34; the first amplifying circuit 34 performs isolation amplification processing on the received direct current feedback signal, and sends the processed direct current feedback signal to the single chip microcomputer 33, and meanwhile, the single chip microcomputer 33 receives the standard signal sent by the standard circuit 36. Wherein, the standard signal can be set according to the requirement of actual situation. The step of the single chip microcomputer 33 calculating the dc feedback signal and the standard signal according to the preset formula, performing PID operation on the calculation result, and further outputting a corresponding and unique control pulse signal according to the PID operation result to control the output current of the power supply, and the step of the single chip microcomputer 33 calculating the dc feedback signal and the standard signal according to the preset formula is a common technical means in the prior art, and therefore is not described herein again. The control pulse signal output by the single chip microcomputer 33 is processed by the pulse transformer 32 and then reaches the rectification main cabinet 31, and the conduction between the silicon controlled rectifier in the rectification main cabinet 31 and the positive electrode clamping plate 1 and the negative electrode clamping plate 2 is triggered to form a loop so as to control the current flowing through the positive electrode 1 and the negative electrode clamping plate 2.
The single chip microcomputer is preferably STC89C52 RC.

When current flows through the positive electrode 1 and the negative electrode clamping plate 2, the positive electrode 1 and the negative electrode clamping plate 2 generate a direct current feedback signal and an alternating current feedback signal at the same time. The alternating current feedback signal can be used as a standby feedback signal to replace the direct current feedback signal when the direct current feedback signal is abnormal.
Generally, the single chip microcomputer 33 compares the dc feedback signal with the ac feedback signal to determine whether the dc feedback signal is abnormal. The single chip microcomputer 33 determines whether the dc feedback signal is abnormal by comparing the magnitude of the ac feedback signal of the dc feedback signal, and determines that the dc feedback signal is abnormal when the ac feedback signal is greater than the dc feedback signal. And when the alternating current feedback signal is less than or equal to the direct current feedback signal, determining that the direct current feedback signal is normal.
