Feeding and discharging mechanical arm of thermal forming press

Abstract

A feeding and discharging mechanical arm of a thermal forming press comprises cross beams, supporting plates, lifting arms, shuttling arms and end grippers. The cross beams are horizontally mounted on the feed side and the discharge side of the press correspondingly. The supporting plates are mounted on the cross beams in a horizontal sliding manner in the left-right direction through guide rails I fixed to the cross beams. The lifting arms are mounted on the supporting plates in a vertical sliding manner through guide rails II fixed to the lifting arms. The shuttling arms are mounted at the lower ends of the lifting arms in a horizontal sliding manner in the front-back direction through guide rails III fixed to the lower ends of the lifting arms. The end grippers are arranged at the lower ends of the shuttling arms and used for clamping a workpiece on a feeding workbench or a discharging workbench. Supporting plate drive devices drive the supporting plates to horizontally slide left and right, lifting arm drive devices drive the lifting arms to slide vertically, and therefore space locating of the end grippers is achieved. The feeding and discharging mechanical arm does not interfere with a module, efficiency is improved, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulator for loading and unloading a thermoforming press. Background technique [0002] At present, most of the devices used for loading and unloading of presses on the thermoforming production line of automobile structural parts are general-purpose six-degree-of-freedom articulated robots, but the cost of general-purpose robots is high, the performance utilization rate of robots for handling work is low, and there is no manipulator in terms of handling speed The speed is fast, and the rigidity of the robot is not as high as that of the manipulator. In addition, due to the limitation of the mechanical structure of the robot, it is easy to interfere with the mold and the press during handling, which affects the stamping cycle of the press. Contents of the invention [0003] In order to overcome the shortcomings of the above technologies, the present invention provides ...
