Problems solved by technology

However, the height position determination is also inaccurate due to the self-friction of the so-called "z-axis" - i.e. the z-axis drive plus a transmission - which often leads to erroneous measurements

Abstract

The invention discloses a process used for determining height position of an element with respect to an element pick-up device in a pneumatic manner. The process comprises (a) a positioning of a first relative height position of the element pick-up device disposed above an element to be assembled can be carried out, and a low pressure can be generated in a suction channel of the element pick-up device; (b) the element pick-up device can be move downwards toward the direction of the element to be assembled; (c) the pneumatic strength of the element pick-up device can be measured during the moving process, and the pneumatic strength can be used to indicate the air flow condition in the suction channel; (d) the change of the pneumatic strength can be recognized, and the strength of the air flow in the suction channel can be changed; (e) a second relative height position of the element pick-up device during the change of the pneumatic strength can be determined. In addition, the invention also discloses a corresponding system and the element pick-up device provided with the suction channel, which can pick up the element without any mechanical contacts.

Description

technical field [0001] The present invention is an invention in the patch technology field. More particularly, the present invention relates to a process and a system for determining the height position of a component relative to a component pick-up device, and a process for picking up a component with a component pick-up device having an air suction channel. Furthermore, the invention also relates to a control device and a computer program, which can be used to carry out the above-mentioned process of determining the height position of the component relative to the component pick-up device and / or picking up the component by the component pick-up device having a suction channel . Background technique [0002] Within the scope of Surface Mount Technology (SMT), a placement head picks up components to be surface mounted from a component picker and places them at a predetermined location on the component substrate. [0003] In this document, the concept of "component substrat...
