What is Gantry Robot?

Gantry Robot Introduction

A Gantry Robot is a programmed industrial system that can also be referred to as a Cartesian Robot or a Linear Robot.

Gantry robots typically shift in linear paths creating a three-dimensional cubic box of space it can work within. For this reason, the term Cartesian robot is ideal since the overall top-down operation space is bound by two linear paths that cross at right angles to generate the working plane (typically referred to as X and Y.) 

When you attach a third axis (typically referred to as Z), this builds the depth at which the manipulation machine can operate inside the cubical enclosure. 

 

Gantry Robots are used often in pick and place robot applications but have been implemented in a variety of assignments.

A gantry robot consists of a controller mounted onto an overhead system that permits movement across a horizontal plane. CCM belt constrained linear actuators are broadly used in the gantry system from electronic assembly and electronic production to vision systems and industrial robotization. 

Gantry robots are also termed as Cartesian or linear robots. They are ordinarily high systems developed with linear guide rail that perform pick and place applicability, but they can also be employed in welding and other applications.

Gantry robot systems provide the advantage of large work areas and better positioning efficiency. Position accuracy is the capacity of the robot to place a part accurately. The main advantages of CCM linear motion actuators are customized length （max length up to 6000mm）and high efficiency (positioning repeatability ±0.0mm).

Gantry robots are simpler to program, concerning motion, because they operate with an XYZ linear stage coordinate system. 

Another advantage is that they are short and limited by floor space constraints. The compact configuration of the CCM toothed belt axis is beneficial for accumulating space.

Gantry Robot Advantages:

1. 3+ axis of movement of practically any length

2. Scalable

3. Gearbox and motor can be sized according to the no. of series of motion, activity, and speeds

4. Suitable for light to heavy/hanging weights

5. Adaptable and efficient due to linear axes scalability

6. Low-priced

Fact: Cartesian design robots will normally produce the best efficiency.

Gantry Robot Disadvantages:

1. Cannot vary range into or around obstructions

2. Linear slides belts rails are not simply sealed upon the environment

3. Not freestanding: stand or structure or other mounting required

Gantry robot System Benefits:

• Gantry robots can utilize a complete cubic work envelope of 96% of their period and size. 

• A Cartesian robot has three axes. Like their namesake and more recognizable giant relatives, the gantry crane, they are commonly suspended from an X or X/Y axis column on a rigid structure. 

• Coordinates in three axes are ordinarily defined as X, Y, and Z. Each axis is projected at right angles to allow three degrees of motion.

• Gantries are further portrayed by support at both ends or through the addition of a second portion.

• Unlike arm style robots, gantries can simply be calibrated to larger proportions in all three axes.

• Gantry robots are uniquely suited for applications where extra orientation requirements are minimum or where or the parts can be staged before the robot chooses them up.

• Both Cartesian and Gantry robots hold a rectangular or cubic work envelope as opposed to articulated robots who like the links in a human arm have limits to particular movement and a specific arcing scope of motion.

• Their terms are shown a point of movement with large sweeping arcs with areas of positive and negative degrees of movement rotating about the middle of its base and the bearing of each axis.

• Because of their rigid lightweight construction, the Cartesian/Gantry Robots are highly reliable and repeatable. 

• Due to their easy structure, gantry robots are natural to program and easy to visualize when deciding new automation. 

• Most maximum of all Gantry robots is configurable. From a plethora of motor and gearbox options to components and materials, these robots are served to take on the challenges of damp dangerous and dirty conditions.

• The Cartesian Coordinate Robot’s comparatively simple design and straightforward procedure make it highly profitable in manufacturing. Because the individual axes can be easily rearranged, downtime is decreased and maintenance costs are retained to a minimum.

• Besides, the whole system can be dismantled into its parts for use in various single-axis applications. Most importantly, Cartesian Coordinate Robot systems are economical compared to other more complicated robots.

Gantry robot Applications:

Gantry robots have all their axes placed above the workbox which makes them ideal for overhead work methods.

Gantry robots can be applied to hold and position a mixture of end-effectors such as those used in PC Board manufacture, glass cutting dispensing, spraying, stock handling, tray-loading / unloading, palletizing, pick and place, assembly, a liquid jet, printing plotting, plate welding, friction welding, laser cutting, packaging, unitizing, Sorting, scanning, camera positioning. inspection, , flying knives, fastening, and screw driving.
