In today's industrial automation field, truss machines play a vital role.
Truss machines, also known as rectangular coordinate robots and gantry robots, are composed of six parts: structural frame, X-axis assembly, Y-axis assembly, Z-axis assembly, fixtures and control cabinets. Among them, the structural frame is generally composed of structural parts such as columns, and is mostly built with aluminum profiles or square tubes, rectangular tubes, round tubes and other welded parts. Its function is to suspend each axis to a certain height; the X-axis, Y-axis and Z-axis assemblies are the core parts and follow the Cartesian coordinate system; the fixtures have various forms according to the specific conditions of the workpiece, such as vacuum suction cup suction, chuck clamping, support or needle clamp insertion; the control cabinet is like the "brain" of the truss machine, which collects sensor or button input signals through the industrial controller and sends instructions to the actuator.
From the perspective of structural characteristics, some truss machines adopt the cantilever truss robot design. Its cantilever structure enables the robot arm to be supported on the column through the cantilever, greatly expanding the working area. Compared with the traditional fixed or gantry structure, it is more flexible and can move and operate in a larger range. It also has multi-degree-of-freedom movement capabilities, which can realize multiple modes of movement such as up and down, left and right, forward, rotation, and flipping, greatly improving the flexibility of production.
Truss machines have many significant advantages. It has high structural strength, is not easy to vibrate and shake, has strong bearing capacity, good rigidity, and often uses high-strength structural steel; it can realize high-speed linear operation of the X, Y, and Z axes, with high positioning accuracy and very small repeatability error; it works 7×24 hours uninterruptedly and is easy to maintain; it can also be configured as a fully closed-loop system to ensure safe operation. It is widely used in automated production lines, and can realize fully automatic operation processes such as workstation adjustment and trajectory movement of workpieces. It can carry objects and operate tools, save labor costs, and improve production efficiency.
