Dispensing machine positioning method

Abstract

The present invention provides a positioning method for a dispensing machine, which utilizes a machine to drive the dispensing machine to move relative to a return-to-zero correction jig along the X-axis, Y-axis and Z-axis to perform a Z-axis correction step, an X-axis correction step and a Y-axis correction step, to define the coordinates as a virtual origin according to the measured X-axis virtual origin, Y-axis virtual origin and Z-axis virtual origin, so that the machine can use this The virtual origin is used as the reference, and the dispensing positions of the dispensing needles of the dispensing machine are set during the dispensing work, so as to achieve the purpose of applying glue to the appropriate position. Wherein, since the dispensing machine positioning method of the present invention uses a zero-return calibration jig and a zero-return calibration signal to set the virtual origin position of the dispenser, the overall device has a simple structure and low manufacturing cost.

Description

technical field [0001] The invention relates to a glue dispenser positioning method capable of correcting the position of a dispense needle of the glue dispenser. Background technique [0002] When assembling various electronic devices such as electronic chips, optical lenses, touch panels, etc., most of the electronic devices need to use a glue dispenser to dispense glue, so that the electronic components in the electronic device can be combined and fixed. With the advancement of science and technology, the size of various electronic components is getting smaller and smaller. Correspondingly, the dispensing position of the glue dispenser must be very precise, otherwise it will not be possible to apply the glue in the proper position. [0003] The prior art method of dispensing viscose at the correct position, as shown in the invention patent case of Taiwan Patent Certificate No. I367787 "Glue Dispensing Method and Dispensing Machine with Error Correction Function", it is pr...

[0004] However, in addition to errors in the relative positions of the fixture and the parts to be dispensed that must be corrected, every time the dispensing needle on the dispensing machine is replaced, the position of the dispensing needle is bound to have errors , if the position of the dispensing needle is not corrected in time, it will also lead to the problem that the glue cannot be applied to the proper position

[0005] Furthermore, since the dispensing method of the a
