The invention relates to an industrial robot wireless teaching controller which comprises a wireless hand-held teaching box and a main controller. The wireless hand-held teaching box is composed of a hand touch and pen touch display screen, a central processing unit (CPU), a wireless transmitting receiving module, a universal serial bus (USB) interface, a 1394 interface, a high-capacity lithium-ion battery, a switching power supply charger and the like. The main controller is composed of a CPU, a wireless transmitting receiving module, a displayer, a controlling keyboard, a memorizer, a USB interface, a multi-channel servo control output interface, input/output (I/O) control interface, a switching power supply and the like. By means of the wireless hand-held teaching box and the main controller, fifty meter effective wireless encryption communication can be achieved, and mutual interference among multiple sets of control systems in the same environment is prevented. The wireless hand-held teaching box and the main controller control an industrial robot in real time to achieve teaching representation programming, data gathering and manual/automatic control through wireless communications, meanwhile working states and working parameters of the robot can also be displayed and altered in real time, and real-time wireless communication is achieved. Due to the fact that constraint of communication cables does not exist between the teaching box and the main controller control, great convenience is brought to robot programming operation personnel, meanwhile safety of controlling robot is improved, and the fact that modern science and technology bring convenience to production work is embodied.
