Dual-counterweight mechanical arm for conveniently grabbing workpiece

Abstract

The invention relates to a double weight counterbalance manipulator which is convenient for snatching workpieces, pertaining to the field of manipulators for snatching and positioning seed collets. Each side of the two sides of the lower part of an outer shell (2) is respectively provided with a pair of locating bases (4) of a rotating pin of an adding and holding piece; the locating bases (4) ofthe rotating pin of the adding and holding piece are fixed on the two sides of a working hole of an upper lingua-shaped heave (10) on the adding and holding piece that is on the lower part of the outer shell (2) by screws (6); pins (5) arranged on the adding and holding piece B (7) of the manipulator and the adding and holding piece A (3) of the manipulator are fixed on the two sides of the outershell (2) by the locating bases (4) of the rotating pin of the adding and holding piece; the inner lateral sides of the adding and holding piece B (7) of manipulator and the adding and holding piece A (3) of the manipulator are respectively provided with the upper lingua-shaped heaves (10) of the adding and holding piece. The double weight counterbalance manipulator of the invention not only greatly improves the working efficiency, but also does not require manual monitoring during the process of snatching, thus having the advantage of cost-saving, etc.

Description

technical field [0001] The invention belongs to a manipulator for conveniently grasping and placing a seed crystal chuck, in particular to a manipulator with double counterweights for conveniently grasping workpieces. Background technique [0002] Usually in the production process of silicon core, the grasping structure with steel ball positioning is used. Its working principle is as follows: There are semicircular concave grooves on both sides of the seed crystal chuck, two positioning steel balls on the ferrule, and a positioning block outside the ferrule to limit the movement of the steel balls. When grabbing the seed crystal chuck, the card sleeve now moves downward, and the steel ball is stuck into the semicircular concave groove of the seed crystal chuck for positioning, and then the positioning block immediately catches up with the positioning steel ball to complete the grabbing of the seed crystal chuck Process; when the seed crystal chuck is placed, the positioning...

AI Technical Summary

Problems solved by technology

On the one hand, the defect of this grasping mechanism is that the positioning of the steel ball is not accurate enough, and it is prone to jamming, so it cannot grasp the seed crystal accurately and conveniently;

This not only affects production efficiency, but also causes a waste of human resources
