A finger-gesticulation hand device includes a base frame representing a metacarpal part of the human hand, and at least three digits mounted on the base frame and appearing to be a thumb and at least two fingers. Each digit has at least two phalange portions respectively linked by two joints which permit a flexing movement of the phalange portions between extended and flexed positions. An actuating cord passes through each digit and is actuated by a solenoid actuator unit to pull the phalange portions of the respective digit to the flexed position.

Abstract

A compliant mechanism includes a first unit, a second unit, at least one elastic member and a driver for driving the elastic member to rotate through a predetermined angle. The first and second units collectively define a passage about which the second unit is rotatable relative to the first unit. The elastic member has a plate and first and second shafts which are coaxially connected to two opposite ends of the plate respectively and rotatably connected with the first and second units respectively. The elastic member is rotatable about a co-axis of the first and second shafts and elastically deformable when the second unit rotates relative to the first unit. The elastic member can change its resistance to the rotation of the second unit by rotating; therefore the compliant mechanism has a great safety upon receiving load and is widely applicable in many fields.

Besides, in every injection cycle, a calculating and controlling module is to calculate the differences between the standard filling time and the filling times of the cavities, and according to the differences, the temperatures in the hot runners may be adjusted by a temperature-adjusting device and a warning device may be started. So, the volumetric filling of the cavities can be balanced very quickly, the process can avoid fluctuations of external environment so as to reduce the time for product development, and the quality of production can be maintained.
