Variable-pitch pick and place device

摘要: Improved variable-pitch pick and place devices may include one or more improvements such as a mechanical linkage pantograph linkage, the itself linked to plurality of device-gripping mechanisms arranged in row so keep uniform, though variable, spacing between mechanisms, with number being increased relative parts for reduced tolerance stack-up improved positioning accuracy. The horizontal position be fixed at not an end thereof, desirably within middle third thereof. controlled three points. These points vertically flexible but horizontally link supporting structure pantograph, side endless loop timing belt, other belt. links belt ends made via two end-most mechanisms. by servomotor encoder, controller computer. vacuum tip grounded supplied electrically-conductive tube.
