Embodiment Construction

[0039] figure 1 A light transmission is shown of a measuring device 1 integrated in a force measuring plate 14 comprising two camera units 2 for use in a screen printing machine or a stencil printing machine (not shown).

[0040] In principle, it is advantageous that the measuring device 1 can be integrated in the plate-shaped wiring carrier receptacle 4b. In order to be able to use the assembly and at the same time also determine the scraper pressure, the optical measuring device 2 is integrated in the force-measuring plate 14 serving as the wiring carrier support 4 b.

[0041] In the force measuring plate 14, between the cover plate 20 and the base plate 21, the force sensor 15 (in the figure 1 not shown). Optical measuring device 2 includes two camera units 2 arranged in measuring device 1 . For this purpose, corresponding openings 22 are provided in the cover plate 20 of the measuring device 1, said openings enabling the optical detection of the glass measuring plate ly...

Abstract

The invention relates to a measuring device and a method for screen printing machines and stencil printing machines, which enable a quick, simple and reliable determination of deviations and machine performance values ​​of the final printing machine for accurate relative to the die Ground-oriented wiring support. In parallel to this, a detection and optionally joint evaluation of the force-time-curve on the printed surface should be possible. Measuring method for screen printing machines and stencil printing machines with the aid of a measuring device arranged below the printing plane, based on the fact that the measuring device communicates with a camera unit during and / or at the end of a printing cycle Corresponding reference marks on the stamp abutting on the measuring plate are detected in relation to at least two marks on the measuring plate arranged in the position of the printing object and between the marks and the corresponding reference marks are respectively determined along the X direction. and the deviation in the Y direction.

Description

technical field [0001] The invention relates to a measuring method and an associated measuring device for screen printing machines and stencil printing machines. The invention is especially intended for use in screen printing machines and stencil printing machines for quality assurance. [0002] For automated manufacture of wired standoffs It is important to print wiring supports, such as printed circuit boards, with a printing medium, such as solder paste. It is important here that the printing medium is applied precisely at the correct point on the wiring carrier. Printing takes place by means of a die, such as a printing screen or a printing template, and a squeegee moving over it, which presses the printing medium through openings provided in the die and thus applies it to the wiring carrier. [0003] The invention stipulates that the measuring device arranged between the stamp and the machine table is provided with at least one camera unit for detecting the position o...
