Three axis mechanical arm automatic grabbing device

Abstract

The invention relates to a three axis mechanical arm automatic grabbing device. According to a X axis direction moving mechanism of the three axis mechanical arm automatic grabbing device, a driving pedestal and a driven pedestal are provided with a first linear guide rail respectively; each T-shaped sliding block is arranged on a corresponding first linear guide rail; a first servo motor arranged on the driving pedestal is connected with a first lead screw via a first coupler; a first nut engages with the first lead screw is fixedly connected with a first connecting plate; the T-shaped slide block arranged on the driving pedestal is connected with the first connecting plate and a transverse connecting plate. According to a Y axis direction moving mechanism of the three axis mechanical arm automatic grabbing device, two linear guide rails are arranged on the transverse connecting plate; a second servo motor is connected with a second lead screw via a second coupler; a second nut engages with the second lead screw is fixedly connected with a second slide block. According to a Z axis direction moving mechanism of the three axis mechanical arm automatic grabbing device, a third linear guide rail is arranged on a guide block of a second slide block; the top of the third linear guide rail is connected with a cylinder; an expansion link of the cylinder is connected with the second slide block; the bottom of the third linear guide rail is provided with a grabbing cylinder; the grabbing cylinder is connected with a robohand. The three axis mechanical arm automatic grabbing device is simple in structure, and low in manufacturing and application cost.

Description

technical field [0001] The invention relates to an automatic grasping device of a three-axis mechanical arm, which is used in the technical field of vehicle lamp assembly. Background technique [0002] The headlights of motor vehicles are installed on both sides of the head of the car for the illumination of roads at night. The headlight is mainly composed of three parts: the light source, the reflector and the light distribution mirror. The light source, the reflector and the light distribution mirror are all installed between the lamp housing and the lampshade. The service life of the headlight and the brightness of the light beam during use, so after crimping the glued lamp housing and lamp shade, use a Martin gun to fix the nails along the lamp housing into the periphery of the lamp shade. [0003] At present, during the assembly of automobile lamps, all parts are transported to the assembly line and manually assembled by hand. On the one hand, it will affect the assemb...

Problems solved by technology

[0003] At present, during the assembly of automobile lamps, all parts are transported to the assembly line and manually assembled by hand. On the one hand, it will affect the assembly quality, that is, affect the appearance of the car, and cannot guarantee the consistency of each batch of lamps.

On the other hand, manual assembly is adopted, the operators are very laborious, the labor intensity is high, and the production efficiency is low.
