A high temperature pickup manipulator

Abstract

The invention provides a high temperature pickup manipulator with fingers. The positions of the fingers are adjustable; the finger feed is controlled by air cylinders. The fingers are used for clamping and fetching work pieces. The fingers are provided with gaskets used for lifting the work pieces. A baffle plate is arranged between the work pieces and the air cylinders and the like. The baffle plate isolates the work pieces and the air cylinders and the like above the work pieces, so that high-temperature work pieces are prevented from burning upper members. The high temperature pickup manipulator is arranged on a telescopic arm which drives the manipulator to perform feed movement; the telescopic arm is a two-stage telescopic arm, wherein the first-stage telescopic arm drives the second-stage telescopic arm to move at higher speed via a belt. The telescopic arm is simple in structure, small in size and high in moving speed.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a high-temperature picking manipulator. Background technique [0002] Hot stamping forming technology is a process in which the sheet is heated to a high temperature of more than 900 degrees, and then quickly transferred to a mold with cooling function for forming and quenching to obtain ultra-high-strength formed parts. However, in the hot stamping automatic production line, in order to prevent the heated plate from cooling down too quickly after being in contact with the air, it is required to be able to quickly transfer the high-temperature plate, and because the distance between the furnace and the punching machine on the production line should be as small as possible, In order to save transportation time, it is applied to the structure of the robot arm. The robot arm can imitate certain actions and functions of the human hand or arm, and is used to grab and carry objects or o...

Problems solved by technology

[0003] Although the existing high-temperature pick-up manipulator can achieve the function of picking up the workpiece and rescue people from the harsh working environment, there are still many deficiencies in the existing high-temperature pick-up manipulator. Because the temperature of the workpiece plate reaches 800°C-900°C, the temperature is too high High, it is impossible to use the common vacuum suction cup as the main structure of the end picker. At the same time, due to the high temperature of the sheet, it is easy to burn other parts on the manipulator and cause damage; Soft, the tensile strength becomes smaller, which makes it difficult for the end picker to use the rigid clamping method to grab the plate coming out of the furnace. Try to keep the high temperature state until the stamping is completed, and the plate coming out of the furnace every second The temperature will drop by tens of degrees, so the movement speed of the manipulator is required, but the movement speed of the manipulator in the prior art is not ideal; due to the irregular shape of the plate, the shape of the plate is usually a rectangular shape symmetrical to the axis, but the side line is an irregular curve , in this case, forming products such as three-jaw cylinders cannot be used; at the same time, due to the small gap between the upper and lower molds of the stamping machine tool, the height of the end of the end picker is limited to a certain size, and the distance between the furnace and the punching machine The distance between them should be as small as possible to save transportation time, which limits the size of the manipulator arm. It is difficult for the existing high-temperature pick-up manipulator to meet the above requirements
