Screw-tightening manipulator and screw-tightening device

Abstract

The embodiment of the invention discloses a screw turning mechanical hand and a screw turning device. The screw turning mechanical hand in the embodiment includes a mechanical arm, a screw turning structure and a feeding structure used for arranging screws and directionally conveying the screws. The screw turning structure and the feeding structure are arranged on the mechanical arm. The screw turning structure comprises an electric screwdriver, a guide rail sliding block, a first fixing plate, a first air cylinder, a cylinder seat and a visual camera used for positioning the positions of screw holes. The guide rail sliding block is fixed to the first fixing plate. The electric screwdriver is arranged on the guide rail sliding block and can slide vertically along the guide rail sliding block. The first air cylinder is fixed to the first fixing plate through the cylinder seat, and the visual camera is fixed to the bottom face of the mechanical arm through a fixing metal plate. By meansof the embodiment, consumed working hours of adsorption type automatic screw turning are greatly reduced, design is conducted according to a standard product manner, debugging is avoided, the screw turning mechanical hand has the plug-and-play effect like domestic electric appliances, main parts are easy to replace, and the product maintenance performance is improved.

Description

technical field [0001] The invention relates to a screw locking operation device, in particular to a screw-tightening manipulator and a screw-tightening device. Background technique [0002] At present, in many manufacturing industries such as electronics, electrical machinery, mechanical hardware, toys and computer peripheral products, the combination and fixation of workpieces are often completed by locking screws, so screws play an indispensable role in daily life and industry. role and is widely used in various fields. [0003] The screw locking method of traditional workpieces is often that the staff hold electric or air screwdrivers, and manually put the screws into the screw holes and then perform the locking operation. Obviously, such an operation is cumbersome and inefficient. When using a split-type screwdriver, the electric screwdriver needs to repeatedly move between multiple screw holes, which is especially cumbersome for products with many screws, such as com...

AI Technical Summary

Problems solved by technology

During the process of taking nails from the turntable, the electric batch cannot screw down the nails, and after the electric batch takes the nails, it needs to rise until the turntable is turned to the avoidance position, resulting in incoherent movement of the electric batch, and the operation takes a long time

[0006] (2) At present, the automatic screwing device is basically implemented in accordance with the project method, and the on-site debugging consumes a lot of manpower and material resources;

[0007] (3) The main components are not easy to replace, and the product maintainability is poor
