Description

Storage device for screen printing flexible printing stock Technical Field The present utility model relates to a screen printing apparatus, in particular a reservoir for flexible printing stock. Background With the development of screen printing, the variety of printing stock is expanding continuously, and flexible printing stock is appearing continuously. For example, a circuit board made of a flexible substrate is usually made of a high-performance material such as a polyester film, polyimide (PI), or Polyamide (PA). The FPC has flexibility and pliability compared to conventional hard sheets, making it suitable for electronic devices and products requiring bending or complex shapes. Because the flexible material can bend, stretch and the like under the action of external force such as gravity and the like, the flexible material lacks necessary rigidity for supporting taking and placing. The flexible printing objects which are stacked and stored are difficult to be reliably sucked under negative pressure when the printing objects are taken. Disclosure of utility model In order to solve the defects, the technical problem to be solved by the utility model is to provide a storage device for stacking and storing screen printing flexible printing objects, which is convenient for carrying out reliable negative pressure suction on the flexible printing objects. The technical scheme includes that the storage device for the screen printing flexible printing stock is characterized by comprising a storage jig and a lifting mechanism, wherein the storage jig comprises a jig bottom plate and a printing stock supporting plate, a plurality of positioning guide rods are fixedly arranged around the jig bottom plate, a plurality of ejector rod through holes are formed in the middle of the jig bottom plate, a plurality of guide rod through holes are formed in the periphery of the printing stock supporting plate corresponding to the positioning guide rods, the guide rod through holes are respectively sleeved on the positioning guide rods, a vacuum breaking groove is formed in the printing stock supporting plate, the lifting mechanism is arranged below the storage jig and comprises a plurality of ejector rods and lifting driving components thereof, the ejector rods are respectively sleeved in the corresponding ejector rod through holes, the top ends of the ejector rods are abutted to the lower surface of the printing stock supporting plate, and the lifting driving components push the printing stock supporting plate to lift along the positioning guide rods through the ejector rods, so that the uppermost surface of a printing stock stack reaches a set position. The utility model has the advantages that a plurality of printing materials are orderly stacked on the printing material supporting plate, the printing material supporting plate is sleeved on each positioning guide rod and is put on the jig bottom plate, each positioning guide rod accurately positions the printing material supporting plate and effectively supports the printing material stack, the lifting driving assembly pushes the printing material supporting plate to stably rise along the positioning guide rod through the ejector rod, so that the uppermost surface of the printing material stack reaches a set position, a picking device (such as a mechanical arm) is convenient to carry out negative pressure adsorption on one printing material on the uppermost surface of the printing material stack, then the printing material stack is conveyed to the next station, and the ejector rod descends and resets after all the printing material stacks are picked up, and is reloaded into the printing material stack. The vacuum breaking groove effectively avoids the problem that the last printing material and the upper surface of the printing material supporting plate are not easily separated based on vacuum negative pressure. Therefore, the working reliability of negative pressure suction of the flexible printing material is effectively improved. Preferably, the upper part of the storage jig is provided with a photoelectric sensing assembly corresponding to the set position, and the photoelectric sensing assembly is in communication connection with a lifting driving assembly. The continuously reduced printing stock stack can be lifted to a set position convenient for negative pressure adsorption every time. Preferably, the upper part of the storage jig is provided with a blowing nozzle corresponding to the set position, and the blowing nozzle is connected with a pressure air source. The problem that the uppermost printing stock and the next printing stock are not easy to separate based on vacuum negative pressure or electrostatic adsorption is effectively avoided. Preferably, the positioning guide rods are arranged at four corners of the jig bottom plate, and two positioning guide rods are symmetrically distributed at two sides of each corner. Further, a blowing nozzle is arranged a
