Truss robot, also known as gantry robot, belongs to rectangular coordinate robot. It is a fully automatic industrial equipment based on X, y, Z  rectangular three coordinate system, which is used to adjust the position of the workpiece realize the trajectory movement of the workpiece. Truss robot can carry objects operate tools to complete various operations. They are fast, accurate, dust-proof antifouling. A complete set of material handling storage designed for automatic turning drilling of bearing workpieces. The equipment can meet the needs of the actual machine tool production line.
Truss robot is mainly composed of multi-dimensional robot walking axis. Each robot travel axis is composed of heavy aluminum profile, roller linear guide servo motor. As a moving frame carrier, the cross section shape of heavy aluminum profile is optimized by finite element analysis, the production capacity ensures its strength straightness.
The roller V-guide is used as a motion guide. The transmission mechanism adopts synchronous belt, rack, pinion ball screw. Kantau's truss robots use profiles square steel as the main frame, are inlaid with linear sliding guide rails, as well as racks pinions. As a mobile frame carrier, the refined profile optimizes the design of cross-section shape through finite element analysis, the excellent production capacity ensures the strength straightness. Over the years, various guideways have been applied improved in various industries, so they are better in reliability, noise reduction, bearing capacity, maintenance free overall performance.
The spatial motion of truss robot is realized by three vertical linear motions. The control core of truss manipulator is realized by industrial controller (such as PLC, motion control, micro controller, etc.). Because linear motion is easy to achieve complete closed-loop position control, the constrained robot can achieve high position accuracy (μ m level). In order to obtain a certain moving space, the structure size of truss robot is much larger than other types of robots. The workspace of truss robot is a space cube. Through the analysis processing of various input signals (various sensors, buttons, etc.) by the controller, after making some logical judgments, the executive command is sent to each output element (relay, motor driver, indicator light, etc.) to complete the joint movement among the three axes x, y, Z, so as to realize a complete set of full-automatic operation process.
Truss robot adopts integrated processing technology, which is suitable for loading unloading of machine tools, production lines, workpiece turnover, workpiece rotation, etc. At the same time, its high-precision clamping positioning tool system provides the robot with standard interface automatic processing, the repeated positioning accuracy is 2 μ m, which ensures the high precision, high efficiency consistency of batch processing products.
