Telescopic robot arm

Abstract

The invention discloses a telescopic robot arm. The telescopic robot arm comprises a front arm and a rear arm, wherein the rear end of the rear arm is fixedly arranged; supports, each comprising an upper support and a lower support, are correspondingly arranged at two sides of the front end of the rear arm; a rack is arranged at one side, corresponding to the corresponding lower support, of each upper support; a chute which is hollowed out is formed in one side, corresponding to the corresponding upper support, of each lower support. The telescopic robot arm further comprises a motor and a controller which are electrically connected with each other; a rotating shaft is arranged at the bottom part of the rear end of the front arm and penetrates the rear end of the front arm; one end of therotating shaft is connected to the output end of the motor through a coupler, and the other end of the rotating shaft is arranged on each chute through a bearing; a gear is arranged between the outputend of the motor and the coupler; the gear is engaged with the rack, and the gear is arranged at a hollow position on the chute in one side; and sliding blocks which fit the chutes are arranged at the bottom parts of the motor and the bearing. According to the telescopic robot arm, one degree of freedom of the robot arm can be achieved; and meanwhile, the degree of freedom of the robot arm is realized, and the robot arm can be telescoped.

Description

technical field [0001] The invention relates to the field of robots, in particular to a retractable robot arm. Background technique [0002] As robots are used in more and more fields, for robots with mechanical arms, whether they can be stretched, stretched length and flexibility restrict the development of robots. [0003] For example, in the catering service industry, although the work of waiters is simple, the working environment depends on people's facial expressions and must endure to clean up the tableware used by customers. With the continuous development of robot technology, food delivery robots have begun to appear in various restaurants. Based on their advantages of no emotion and low cost of use, this type of robot has gradually become popular. But in actual use, when the robot arrives at the dining table, the voice prompts the customer to take away the dishes. Often, because the distance between the customer and the robot is a little far, the customer needs to ...
