Abstract
An automatic racket stringing system includes: two lens modules, respectively shooting a racket thread hole on a racket at a first preset position from different two angles, and the lens modules are based on the angles and determine a first relative coordinate of the racket line hole through a triangulation method; and a control unit controls a robotic arm to grab the racket from an initial position and move the racket to the first preset position; the control unit controls the robotic arm to a second preset position clamps a first end of a racket line, and when the first end of the racket line extends a preset length, it is cut by the robotic arm.

A fully automatic racket stringing system, comprising:
- two lens modules respectively capturing, at different two angles, a racket string hole on a racket at a first predetermined position, wherein the lens modules determine a first relative coordinate of the racket string hole according to the angles and a triangulation;
- a robot arm has a function of cutting off;
- a control unit storing a plurality of programs, the first predetermined position, an initial position, and a second predetermined position;
- and
- a racket string supplying unit, a racket string is wound around the racket string supply unit to make the first end of the racket string be located at the second predetermined position;
- wherein the control unit executes multiple programs to perform the following steps:
- controlling the robot arm to grip the racket from the initial position, and to move the racket and place the racket at the first predetermined position;
- executing a string head recognition program among the programs to control the robot arm to move to the second predetermined position to grip the first end of a racket string, wherein after the first end of the racket string extends a predetermined length, the robot arm performs cutting off;
- the lens modules capture the first end and calculate the second relative coordinate of the first end;
- the step of controlling the robot arm to grip the first end of the racket string to pass through the racket string hole according to the first relative coordinate includes the following steps:
- controlling the robot arm to grip the first end of the racket string and move the first end from the second relative coordinate to the first relative coordinate, and execute a longitudinal stringing process among the programs.
