Abstract

The invention discloses a PCBA board tool suction cup mechanism. The PCBA board tool suction cup mechanism comprises a mounting frame, a rapid switching disc, a suction cup assembly, a floating positioning assembly, an elastic buffering assembly and a pressure sensing assembly. The rapid switching disc is installed on the top of the installation frame and used for achieving rapid and automatic butt joint and switching with the robot. The suction cup assembly is installed at the bottom of the installation frame and used for sucking the PCBA board. The floating positioning assembly is used for being inserted into a positioning hole of the PCBA board to achieve accurate positioning, and repeated positioning accuracy is improved. The elastic buffering assembly is used for providing buffering during assembling and eliminating matching errors. The pressure sensing assembly is used for monitoring the assembling pressure in real time. According to the invention, rapid and automatic remodeling of the tool, high-precision flexible assembly of the PCBA board and intelligent monitoring of the process are realized, and the production efficiency and the product yield are remarkably improved.
