Abstract:

Considering assembly and disassembly of micro-gripper, connection and isolation of lead, a new micro-gripper based on piezoelectric bimorphs is designed by using finite element analysis. First, a detailed structure of the micro-gripper is designed based on piezoelectric bimorph cantilevered beams. Second, static and dynamic characteristics of the micro-gripper are analyzed by piezoelectric coupling field analysis technique of ANSYS. For the static performance, there is a linear relationship between displacement and driving voltage of the micro-gripper. The maximum displacement of the micro-gri

Abstract:

Micro-gripper is a key module in IC/LED wire bonding. The paper presents a micro-gripper combining with piezoelectric material and flexible structure. The dynamic and static characteristics of the micro-gripper are calculated by finite element method, and the natural frequencies, the vibration modes, as well as the deflection range of the micro-gripper are obtained. In the experiment, the high-speed camera was used to track the vibration of the micro-gripper, and the relationship between deflection range and driven voltage was established. The vibration behavior was measured by a non-contact l

Abstract:

In this paper, a kind of micro-gripper is introduced using vacuum adsorption method. The gripper is used to grasp a mm size micro-part in a micro-assembly process. Because of the requirement of the adsorption force, the negative pressure control system is employed which can let the micro-gripper inhale and exhale freely. Accordingly, the adsorption force of the micro-gripper can be controlled accurately. The PLC controller is used to get the pressure information from the electronic proportional valve. The PID control law is employed to adjust the opening of the valve. In this way, the micro-gr

Abstract:

A robotic system for the automatic wire pulling of coreless motor winding is designed, including the design of an opening-closing control system and a micro-gripper’s tip structure with a double-armed elastic-beam structure for the support part and an enveloping clamping structure for the tip part. The micro-gripper captures the electrode wire from the root, encircles the wire after the envelope region is closed, and the thin and flexible electrode wire is pulled to the top of the electrode pad by the movement of the micro-gripper and released. The mechanical index of the micro-gripper is simu

Abstract:

Micro-grippers are highly desired in engineering, robotics, and biomedicine. However, on the basis of satisfying the requirements of miniaturization, precise manipulation, and low power consumption, the existing micro-grippers are difficult to achieve rapid response simultaneously. In this paper, we present a bimorph electrothermal micro-gripper that composed of several metal ultrathin films with high surface-to-volume ratios, allowing rapid heating and cooling processes. Patterns of these films are exquisitely designed so that the micro-gripper naturally forms an embedded circuit to optimize

Abstract:

This paper proposes a modular gripping mechanism for the manipulation of multiple objects. The proposed micro gripper combines traditional machining techniques with MEMS technologies to produce a modular mechanism consisting of a sturdy, compliant aluminium base and replaceable end-effectors. This creates an easily-customisable solution for micro manipulation with an array of different micro tips for different applications. We have provided the kinematic analysis for the gripper to predict the output and have also optimised design parameters based on FEA (finite element analysis) simulation an
