SERVODE Servo Cantilever Beam Linear Robot Applications

In material gripping and handling applications, we use a number of different types of motion devices, such as trusses, robotic arms, robots...etc.

The multi-axis articulated arm robot is characterized by a small footprint and flexible motion, but the working range it can cover is obviously too small, and the multi-joint axis kinematic characteristics also limit its working path; the traditional three-axis truss with dual X-axes + movable bridge can indeed cover a large working range, but because it requires two support beams, the overall space required for the device is very large.

So, is there a motion device that can cover a larger working area with a smaller space footprint when implementing material gripping and handling applications?

Guangzhou Servode Electric Co.,Ltd has introduced a linear robot for cantilever beam applications that solves this problem perfectly.

Working principle explained:

The X-axis is a fixed beam in the horizontal direction with a moving carrier plate mounted on its track;
The Y-axis is a movable horizontal beam arm perpendicular to the X-axis, with a base carrier plate fixed at one end for suspension of the Z-axis;
The Y-axis beam arm is supported horizontally on the moving carrier plate of the X-axis by rollers, and can move laterally reciprocally along the X-axis with this base carrier plate, and can also move longitudinally along the Y-axis by rack and pinion drive;
The Z-axis is a vertically oriented moving arm suspended on the fixed carrier plate at one end of the Y-axis, which can move horizontally in the X and Y directions with the Y-axis beam arm on the X-axis side in the plane, and can also move vertically along the Z-axis by rack and pinion drive.

Mechanical structure features:
The moving beam arm of Y-axis is supported on one X-axis and can move horizontally along X-axis with the carrier plate or reciprocate along Y-axis as a whole;
The base carrier plate of Z-axis is fixed at one end of Y-axis, and the movement of its lifting arm is realized by the overall movement of Y-axis beam arm in both X and Y directions.

Advantages:
1. Saves the space occupied by the handling device itself, while ensuring that a large working area can be covered
With only one X-axis, the Y-axis moving beam arm and Z-axis lifting arm appear to be suspended in mid-air, which is the origin of the product name - CP (Cantilever Portal).
2. Compact and space-saving
Compared to a 3-axis truss with a movable bridge and dual X-axes, the CP does not require a second support beam, making it more compact and taking up less space.


3. More flexible and efficient
Compared with the six-axis articulated arm robots commonly used in industrial sites, cantilever beam robots can cover a much larger working range and are more flexible and efficient because they do not have the limitation of axis kinematics.
