Industrial robots are currently used more and more widely. In the manufacturing industry, many industrial robots with different purposes are involved in production, which brings more benefits to enterprises And convenient, the most common in industrial production are four-axis industrial robots and six-axis welding robots.
First, first explain the motion routes of each axis.
1. Three-axis
You can pick up an object, lift it, move it horizontally and vertically, and set it up or present a robot within reach of X, Y, Z space without changing the direction of the object
2. Four-axis
You can pick up an object, Lift it, move it horizontally, and set or present it in X, Y, Z space. Change the direction of the object along one axis (for example, yaw)
3. Five axis
You can pick up an object, lift it, move it horizontally, and set it on X, Y, Z space changes the direction of the object along two axes (yaw and pitch)
4. Six-axis span>
You can pick up an object, lift it, move it horizontally, and set it in X, Y, Z space to change the direction of the object along Three axes (yaw, pitch and roll).
5. Seven axis
The movement capabilities of all six-axis robots follow the linear direction of the ability (usually horizontal movement, moving the robot from one place to another along the track).
The difference between four-axis and six-axis welding robots
Four-axis
First of all, let’s talk about the four-axis welding robot. Among the small assembly robots, the "four-axis robot" is Refers to "selective assembly of articulated robotic arms", that is, the arm part of a four-axis robot can move freely in a geometric plane. The first two joints of the robot can freely rotate left and right on the horizontal plane. The third joint consists of a metal rod called a feather and a holder. The metal rod can move up and down in a vertical plane or rotate around its vertical axis, but cannot tilt. This unique design makes the four-axis robots have strong rigidity, so that they are capable of high-speed and high-repetitive work. In packaging applications, four-axis robots are good at high-speed pick and place and other material handling tasks.
Six axis
Six axis The welding robot has two more joints than the four-axis welding robot, so it has more "degree of freedom of movement". The first joint of the six-axis robot can rotate freely in the horizontal plane like a four-axis robot, and the latter two joints can move in the vertical plane. In addition, the six-axis robot has one "arm" and two "wrist" joints, which gives it the capabilities of a human arm and wrist. The more joints of six-axis robots means that they can pick up any parts on the horizontal plane and place them in the packaged products at a special angle. They can also perform many operations that can only be done by skilled workers.
