Toshiba Machine’s TH Series was upgraded to the TH-A Series of extreme performance Scara Robots. Consisting of three models, the TH650A, the TH850A and the TH1050A, these robots offer a 20 – 30 percent improvement in cycle time (with higher payloads) compared to previous models. Standard cycle times are 0.31 sec with a 2 Kg payload for the TH650A, and 0.39 sec with a 5 Kg payload for the TH850A and the TH1050A. X-, Y- and Z-Axis positioning repeatability for all three models is ± 0.01 mm, while C-Axis positioning repeatability is ± 0.004 deg.
The rigid construction and vibration-free performance of the TH-A Series result in a longer robot life. The TH-A Series features a sealed labyrinth structure as standard. Piping positions are flexible, and may easily be changed by the end-user. What’s more, because two harnesses are in the robot arm, it is easy to replace them. Other features of the TH-A Series include lower profiles, reduced noise levels and easy maintenance. Maximum payload mass for the TH650A is 10.0 Kg and maximum composite speed is 7.52 m/s, while the TH850A and TH1050A can each carry 20.0 Kg (TH850A maximum speed is 8.13 m/s and TH1050A reaches up to 9.15 m/s).
The TH-A Series includes a full-function TS Controller. This highly advanced controller is easy to operate and can control a maximum of five axes simultaneously. It includes a built-in PLC, a multitask function and many more features.
