The technical parameters of the manipulator reflect the competent work of the manipulator and the highest operating function it has, and are all necessary considerations for the selection, planning and application of the manipulator. The main technical parameters of the manipulator generally include the following seven: degree of freedom, resolution, accuracy, repeat positioning accuracy, working range, carrying capacity and maximum speed, etc.

The main technical parameters of the injection manipulator---resolution introduction:

In manipulators, accuracy is often easily confused with resolution and repeat positioning accuracy. The resolution of the manipulator is determined by the system planning detection parameters, and is affected by the function of the position response detection unit.

The resolution is divided into programming resolution and control resolution, collectively referred to as system resolution.

Editing resolution refers to the minimum distance unit that can be set in the program, also known as the benchmark resolution. For example: when the motor rotates 0.1 degrees and the linear distance of the mechanical wrist point, that is, the tip point of the arm, is 0.01 mm, the reference resolution is 0.01 mm.

The control resolution is the smallest displacement that can be detected by the position response circuit. For example: if an incremental encoder disc with 1,000 pulses per week (revolution) is coaxially installed with the motor; then every time the motor rotates 0.36 degrees (360 degrees, 1,000 r/min), the encoder disc sends out a pulse, 0.36 degrees The following angle changes cannot be detected, and the control resolution of this system is 0.36 degrees. Obviously, when the programming resolution is equal to the control resolution, the system function reaches the highest.
