AI Technical Summary

Technical Problem

During the IC component testing process, the existing four-jaw positioning mechanism occupies a large volume and is prone to vibration, resulting in test errors and IC components damage, and the motor drive complexity and cost are high, which affects the positioning accuracy.

Method used

A four-jaw positioning and steering mechanism is designed, and adopts a combined structure of base, support seat, motor, electromagnet, lifting assembly and clamping assembly. The lifting assembly and clamping assembly are driven by the motor to rotate, and the clamping assembly is used to achieve the opening and closing of the clamping claws and positioning of the workpiece using the sliding disc of the electromagnet and polar material.

Benefits of technology

The mechanism only requires a set of driving motors and electromagnets to realize the center positioning and rotary positioning of the IC components, reducing the cost of production, assembly and maintenance of the device, and improving the positioning accuracy and testing reliability.

Abstract

The present invention discloses a four-claw positioning and steering mechanism, including a base, a support seat 1, a support seat 2, a motor, an electromagnet, a lifting assembly and a clamping claw assembly; the support seat 1 is installed on the base, the support seat 2 and the motor are installed on the support seat 1, the electromagnet is fixedly installed on the support seat 2, and the lifting assembly and the clamping claw assembly are rotatably installed on the support seat 2 through a bearing 1; the sliding plate of the lifting assembly adopts a polar material and is arranged adjacent to the electromagnet along the axial direction, so as to realize the axial adsorption and separation of the sliding plate through the switching of the electromagnet, thereby driving the top rod to rise and fall along the slide slot through the sliding plate, and then driving the clamping claw assembly to open and close through the top rod to realize the pick-up and placement positioning of the workpiece. The four-claw positioning and steering mechanism provided by the present invention only needs a set of driving motors and electromagnets to effectively perform the centering and rotation positioning of electronic components, which effectively reduces the manufacturing and assembly maintenance costs of the device.
