Description

Vacuum suction nozzle assembly of grabbing manipulator of plate loading machine Technical Field The utility model relates to the technical field of machining, in particular to a vacuum suction nozzle assembly of a grabbing manipulator of a plate feeding machine. Background In modern industrial production, the plate feeding machine is used as one of key equipment for realizing an automatic production flow, and the performance of the grabbing manipulator directly influences the production efficiency and the product quality. Along with the increasing demands of the manufacturing industry for automatic and intelligent production, the grabbing manipulator of the plate feeding machine is widely applied to various industries such as electronics, semiconductors, automobile manufacturing and the like. The device can rapidly and accurately grasp and carry the materials such as plates, reduce manual intervention and improve the continuity and stability of production. The existing plate feeding machine grabbing mechanical arm needs to use grabbing mechanical arms of corresponding types for workpieces of different types, so that multiple types of machines are needed to be prepared, the cost is increased, and in the running process, the stability is insufficient. Because the manipulator can produce great vibrations when high-speed motion and frequently start and stop, this not only can influence the precision of snatching, leads to panel location inaccuracy, still probably causes the damage to the spare part of manipulator self, shortens the life of equipment. Meanwhile, in the grabbing process, for boards with different materials and surface conditions, the existing grabbing mode is difficult to ensure reliable adsorption force all the time, and the situation of grabbing failure is easy to occur, so that the production efficiency is affected. Disclosure of Invention The utility model aims to provide a vacuum suction nozzle assembly of a gripping manipulator of a plate feeding machine, so as to solve the problem of poor adaptability of the existing gripping manipulator of the plate feeding machine in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The vacuum suction nozzle assembly of the grabbing manipulator of the plate feeding machine comprises a grabbing mechanical arm for the plate feeding machine, a fixing seat is arranged at the fixed end of the grabbing mechanical arm, a vacuum negative pressure pump is arranged at the movable end of the grabbing mechanical arm, a suction cup-shaped negative pressure suction nozzle is arranged at the air inlet end of the vacuum negative pressure pump, an external threaded pipe is connected with the air inlet end of the vacuum negative pressure pump, an internal threaded connector which is matched with the external threaded pipe in size and in threaded connection is arranged at the top of the negative pressure suction nozzle, an air outlet end is arranged at the top of the vacuum negative pressure pump, and a detachable net cover is arranged at the air outlet end. Preferably, the shock pad is installed at the bottom of fixing base for snatch robotic arm and can obtain effective buffering at the vibration that the operation in-process produced. Because the manipulator is frequently started and stopped and when high-speed motion, vibrations can be transmitted to whole equipment, influence equipment stability and snatch the precision, and the shock pad reducible this kind of adverse effect guarantees equipment steady operation. Preferably, the shock pad is a rubber shock pad, the thickness of the shock pad is 1-4mm, and rubber has good elasticity and shock absorption performance and can effectively absorb shock energy. The thickness range of 1-4mm ensures the damping effect and simultaneously gives consideration to the installation space and cost of the damping pad, so that the damping pad achieves better balance in practicality and economy. Preferably, the bottom of the net cover is provided with a plugging ring seat which is matched with the inner diameter of the air outlet end of the vacuum negative pressure pump in a plugging manner, so that the net cover can be stably arranged at the air outlet end of the vacuum negative pressure pump. The plugging mode is convenient to install and detach, can ensure that the net cover is tightly connected with the air outlet end, prevents the net cover from loosening, effectively blocks sundries from entering the pump, and protects the normal operation of the pump. Preferably, a sealing gasket is arranged at the joint of the external threaded pipe and the air inlet end of the vacuum negative pressure pump, so that a tiny gap at the joint can be filled, and the tightness of the connection is enhanced. Because if the junction is sealed poorly, can lead to gas leakage, influence vacuum negative pressure pump and produce sufficient negative pressure, and then in
