Problems solved by technology

The contact between the cam and the frame of the plane mirror is in the form of a high pair. For a high-speed placement machine with a mounting speed of tens of thousands of pieces per hour, the number of actions between the frame of the plane mirror and the cam is thousands of times per hour, which will inevitably cause the cam Surface fatigue shortens the life of the cam, and also limits the further improvement of the placement speed of the placement machine

Abstract

An optical path control system for a high speed chip mounter image detection system is disclosed and relates to optical path control technologies for a high speed chip mounter. The optical path control system is used for solving a problem that a cam which is used for driving a reflective mirror is short in service life and high in cost and therefore the cam is not suitable for optical path control. A side wall on one end of a reflective mirror rack is used for fixing the reflective mirror while the other end of the reflective mirror rack is provided with grooved pulley, the reflective mirror rack is hinged onto the high speed chip mounter, the grooved pulley is provided with two grooves, locking arcs of the grooved pulleys are matched with an external arc of a cutaway disk, a rotating arm is fixedly connected with the cutaway disk, one end of the rotating arm is hinged onto a first machine rack of the high speed chip mounter while the other end of the rotating arm is hinged onto a cylindrical pin, a notch arc of the cutaway disk is equally divided by the rotating arm, the cylindrical pin is perpendicular to the rotating arm, a diameter of the cylindrical pin is equal to width of each groove, a driving device is used for driving rotation of the cutaway disk, and rotation of the reflective mirror rack is driven via the cylindrical pin. The optical path control system is suitable for the high speed chip mounter image detection system.

Description

technical field [0001] The invention relates to the optical path control technology of a high-speed placement machine. Background technique [0002] There are many types of high-speed placement machines, but the overall structure is generally similar. High-speed placement machines usually use a placement head with a flying camera to detect and place components. At present, there are two detection methods of the flying camera of the existing placement machine, one of which is to install a flying camera that matches the number of nozzle heads under the placement head; the other is to install a flying camera at the bottom of the placement head. Multiple nozzle head elements are inspected in a reciprocating motion. In order to maximize the efficiency of component detection, high-speed placement machines generally use the first method to detect components. Usually, the movement direction of the nozzle head and the camera shooting path are usually arranged in a vertical manner,...
