A robotic sealing column

Abstract

The invention relates to a robot sealing column, the column frame is installed in the outer cover, the ball screw is rotatably installed on the column frame, and is connected with the driving motor installed outside the outer cover, the ball screw is screwed with a screw nut, and the screw nut is connected There is a skateboard carriage; the upper and lower ends of the outer cover are equipped with sealing intermediate wheels, the end face of the column skeleton is in the shape of a "mouth", which is an internal hollow structure, and one end of the sealing belt is bypassed by the inner side of the "mouth" end face of the upper end. After the sealing intermediate wheel is wound to the outside of the "口"-shaped end face, it is connected with the upper end of the skateboard frame, and the other end of the sealing tape is wrapped around the lower sealing intermediate wheel from the inner side of the "口"-shaped end face to the "口"-shaped After the outer side of the end face, it is connected with the lower end of the skateboard frame. The drive motor drives the ball screw to rotate through the transmission mechanism, and the screw nut drives the skateboard frame to rise and fall relative to the column frame. The invention satisfies the basic functions of the robot, and at the same time achieves the purposes of sealing the joints of the robot, being dust-free and improving the dynamic performance of the robot.

Description

technical field [0001] The invention relates to a robot in flat panel display and integrated circuit industries, in particular to a robot sealing column. Background technique [0002] Flat panel display (FPD) is another large-scale industry developed after integrated circuit (IC). The glass substrate is one of the key basic materials of the FPD industry, and the manufacturing process of the FPD industry requires a high degree of automation and unmanned operation. Therefore, handling robots have been introduced into the FPD industry to achieve smooth handling and precise positioning of glass substrates. [0003] There are many stations of the glass substrate handling robot that need to be sealed by the robot. The protection level is IP54 ("5" means completely preventing the intrusion of foreign objects. Although it cannot completely prevent the intrusion of dust, the amount of dust intrusion will not affect the normal operation of electrical appliances; "4" means Prevent wa...

Problems solved by technology

While sealing, it is also necessary to ensure no dust, and dust will be produced after drying; the conventional contact seal of the robot joint will produce dust due to friction; the conventional contact seal of the robot joint will produce random joint resistance, which will affect the dynamic performance of the robot
