Description
Technical field
The invention belongs to RFID label manufacturing equipment field, more specifically, relate to a kind of for RFIDThe substrate conveyance system of Tag Packaging.
Background technology
In the production process of RFID label, generally include antenna printing, Tag Packaging, antenna detection,The processing step such as cut and compound. The effect of RFID Tag Packaging is that chip is taken from Wafer dishWith antenna laminating, realize Inlay encapsulation by conducting resinl hot-press solidifying afterwards. Sealed in unit is generally by pointRubber moulding piece, mount the compositions such as module, hot pressing module, detection module and substrate conveyor module, Qi ZhongjiThe process that plate is carried and control thereof are played key effect for the quality of production of RFID label.
In prior art, propose some and related to equipment and the application thereof that RFID label is produced, for example,CN201210155932.4 has proposed a kind of antenna detection equipment, and this equipment comprises clamp assemblies, only complies withThe tenslator of tension force is provided to provide by floating roller, and the mechanical deflection correcting being formed by correction ribDevice etc. But, in above-mentioned RFID Tag Packaging equipment, to the tension force control in substrate transportation processMainly conducted oneself with dignity to realize by floating roller, Tensity size cannot arrange, and can not meet the production of polytypic substrate;And floating roller impulsive force in dropping process is large, unfavorable to substrate.
Except above-mentioned deficiency, the correction mode of existing substrate conveyance system mainly comprises that machinery entanglesTwo kinds of modes of inclined to one side and integrated automatic deviation correction. Mechanical deflection correcting is a rib of each installation on substrate both sides,Utilize rib to stop substrate skew, this deviation correcting device can not ensure substrate lateral shift precision. OneThe operation principle of body automatic deviation rectifying device is: deflection correction sensor is by the substrate lateral attitude letter detectingNumber pass to controller, after controller compares, amplifies, calibrates signal, drive motors running,Deflection framework is swung, realize substrate automatic deviation rectifying function. This integrated automatic deviation rectifying device has one of one's ownBody, can not be incorporated in packing equipment control system, makes to have the sealed in unit behaviour of multiple deviation correcting devicesDo inconvenience. Especially, traditional correction detection mode only has opposite side, detects state to center and to lineThe integrated automatic deviation rectifying device of inside and outside all RFID label producing apparatus all adopts these detection modes,These detection modes can only detect substrate position, but in some operation of actual production,Chip position is only monitored main body, instead of substrate position. In the hot pressing module of RFID sealed in unit,As excessive in actual lateral position and the theoretical lateral attitude gap of fruit chip on substrate, even substrate horizontal strokeAccurate to position, also can cause hot pressing to lose efficacy, thereby affect product quality.
In addition, can there is deflection deformation while mounting the each roll shaft between module and hot pressing module in substrate process,This is very large to the harm of uncured chip, how to reduce the impact of roll shaft on chip, will be to improveThe key point of yield rate. On the other hand, existing RFID Tag Packaging equipment substrate conveyance system is notPossess splitting function, the substrate that need to cut for some can only use and divide after packaging process finishesThe machine of cutting is cut, and can cause like this production efficiency low, and increases tag damage rate.
