Embodiment Construction

[0018] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] figure 1 A position detection sensor 1 of a reference position automatic alignment device of a dispensing needle of a dispensing machine is shown, and the position detection sensor 1 is usually installed on a working platform of a dispensing machine. Dispensers usually include multi-axis manipulators, such as XY-axis manipulators or XYZ-axis manipulators. The dispensing needle is mounted on a multi-axis manipulator so that it can be moved to the desired position as needed. In the shown embodiment, the position detection sensor 1 is a rectangular box-shaped body, of course, it can also be in other shapes. The position detection sensor 1 can be connected to the control system of the glue dispenser through wires. Therefore, the control system supplies power to the position detection sensor 1 on the one hand, and receives the detection signal f...

Abstract

The invention relates to a reference position automatic alignment method and device of a glue dispensing needle of a glue dispensing machine. The method comprises the following steps: a position detecting sensor is provided; a square hole is formed in the position detecting sensor; an X-directional light emitter and an X-directional light receiver, and a Y-directional light emitter and a Y-directional light receiver are arranged in the center positions of each pair of opposite inner walls of the square hole; the glue dispensing needle moves in the square hole through a multiaxis manipulator inan X direction; the Y-directional light receiver generates a pulse signal; positions corresponding to an ascending edge and a descending edge of the pulse signal are recorded as X1 and X2; an X-directional reference position X of the glue dispensing needle is (X1+X2) / 2; the glue dispensing needle moves in a Y direction in the square hole through the multiaxis manipulator; the X-directional lightreceiver generates another pulse signal; positions corresponding to an ascending edge and a descending edge of the pulse signal are recorded as Y1 and Y2; an Y-directional reference position Y of theglue dispensing needle is (Y1+Y2) / 2; and the glue dispensing needle automatically moves to a reference position (X, Y) through the multiaxis manipulator.

Description

technical field [0001] The invention relates to the field of dispensing machines, in particular to a method and device for automatically aligning a reference position of a dispensing needle of a dispensing machine. Background technique [0002] The glue dispenser is more and more widely used because of its high working efficiency and uniform glue dispensing. However, the reference position alignment of the dispensing needle of the existing dispensing machine is realized by the manual operation of the worker: that is, a cross-shaped mark is drawn on the work platform, and then the manipulator is operated to move the dispensing needle to the top of the cross-shaped mark, so that The dispensing needle is aimed at the center (intersection) of this cross mark. This alignment method has low precision, is time-consuming and requires experienced workers to operate. Contents of the invention [0003] The present invention aims to provide a method and device for automatically alig...
