AI Technical Summary

Technical Problem

Existing industrial robots for loading and unloading are unable to avoid warping, increased material brittleness, and clamping damage caused by thermal stress when transporting large, thin PCB boards. In particular, fixed-stroke clamping plates cannot adapt to warping, floating clamping response is slow, and vacuum suction cups are prone to failure.

Method used

By employing the collaborative work of the clamping unit and the control unit, the edge posture information of the PCB board is obtained in real time through the attitude sensing component, and the position of the support component and the clamping force are dynamically adjusted to achieve adaptive clamping and change the clamping method to surface contact to disperse stress.

Benefits of technology

It achieves adaptive clamping of micro-warping PCB boards at high temperatures, avoiding mechanical damage, improving work efficiency and safety, and ensuring high-precision, damage-free transportation.

Abstract

The application relates to the technical field of industrial robots, and discloses an automatic feeding and discharging industrial robot and a control method thereof. The automatic feeding and discharging industrial robot comprises a robot body, a clamping unit arranged at the tail end of the robot body, and a control unit; the clamping unit comprises two clamping bodies, a clamping driving component for driving the two clamping bodies to move towards or away from each other, and two auxiliary supporting components arranged on the clamping bodies correspondingly; the auxiliary supporting component comprises a supporting piece, a fine adjustment driving piece and a posture sensing piece; and the supporting piece is movably arranged on the clamping body. Through the intelligent cooperation of the clamping unit and the control unit, the application realizes self-adaptive clamping and carrying of the microscopic random warping of a high-temperature PCB after reflow soldering; the risk of mechanical damage such as PCB edge micro-cracking and pin deformation is reduced; and zero-damage precision carrying in a special scene of the high-temperature PCB after reflow soldering is realized.
