Novel intelligent universal high-speed screwing assembly robot

Abstract

The invention discloses a novel intelligent universal high-speed screwing assembly robot. The novel intelligent universal high-speed screwing assembly robot comprises a horizontal joint robot base which comprises a locking device and an ejection device. The horizontal joint robot base realizes position adjustment in the horizontal X direction and Y direction. The locking device realizes movement and rotation in the Z direction through a spline assembly to finish the locking movement of a screw. The ejection device enables the screw to be attached to the lower end of a lever, and the screw locking accuracy is improved. The novel intelligent universal high-speed screwing assembly robot is based on the prototype of a horizontal joint robot, the locking device is realized by ingeniously using the spline assembly structure in the horizontal joint robot, and the novel intelligent universal high-speed screwing assembly robot is good in universality and high in stability.

Description

technical field [0001] The invention belongs to the field of robot design, and in particular relates to a robot that automatically moves and positions screw holes through X, Y, and Z coordinates, performs automatic locking or fastening, and realizes a fully automatic assembly process of screws, nuts or rivets. Background technique [0002] In the structural design of electronic appliances, communication home appliances, mechanical products, automobile industry and aerospace parts, the use of screws or rivets is the most common method. Therefore, in the assembly process of these products, screwing and locking screws or rivets become a the most basic operation. As we all know, using a manual screwdriver in the past assembly process is a primitive manual operation method. With the advancement of technology, people later invented electric screwdrivers suitable for mass production and mechanized operation. The appearance of this electric tool has played a positive role in promo...

AI Technical Summary

Problems solved by technology

[0006] 1. When the screwdriver and the screwdriver head go down together, the axial impact force cannot be small due to the influence of the screwdriver's own weight, and it is easy to damage the locked product;

[0007] 2. The locking mechanism is complex, large in size, and heavy in weight, which requires high load on the robot, which affects the locking speed and equipment dimensions, and the cost is high;

[0008] 3. There is no standardization institution, the production cost is high, the cycle is long, and the stability is poor;

[0009] 4. The locking height cannot be changed arbitrarily and lacks flexibility
