Description

Background

The current IC card has large traffic and large demand, and has high requirement on the productivity of the equipment for producing the IC card; in the process of IC card code spraying, code spraying is required to be carried out on the front side and the back side of the IC card. Most of the existing production equipment is provided with two sets of DOD (drop on demand ink jet) code spraying devices on a transportation channel, and a card turnover device is arranged between the two sets of DOD code spraying devices to turn the front and the back of an IC card. And procedures such as corona, cleaning, speed measurement, UV curing and the like are needed to be carried out on the IC card before the DOD code spraying, so that the installation sequence of the two sets of DOD code spraying devices is as follows: corona device #1, cleaning device #1, speed measuring device #1, DOD spouts a yard device #1, UV solidification device #1, speed measuring device #1, IC-card upset buffer memory, corona device #2, cleaning device #2, speed measuring device #2, DOD spouts a yard device #2, UV solidification device #2, speed measuring device #2, the during operation IC-card spouts the sign indicating number to positive and negative two sides through above-mentioned device in proper order, causes DOD like this to spout a yard module equipment length longer, area is big, the device is more, the module cost is higher, equipment stability is poor. If a set of DOD code spraying device is used for code spraying, a certain number of IC cards need to sequentially pass through the device in a conveying line, then the front code spraying is carried out, the IC cards are turned over after the front code spraying, and the IC cards are conveyed back to the DOD code spraying device for back code spraying. Therefore, in the time period of spraying the IC cards, new cards cannot be added into the DOD code spraying module equipment, and the new cards can be continuously conveyed only after all the cards are sprayed and conveyed out of the equipment to enter the DOD code spraying module equipment, so that the next cycle of DOD code spraying is performed, the productivity is reduced, and the productivity requirement cannot be met.
