Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0017] The fifth step of alignment adjustment mentioned above in the background art requires that the graphic area on the screen 8 be aligned with the carbon ink graphic to be printed on the ceramic substrate 6 . Because when the center of the graphics area on the screen 8 is aligned with the center of the carbon ink graphics to be printed on the ceramic substrate 6, the graphics area on the screen 8 and the carbon ink graphics to be printed on the ceramic substrate 6 are also aligned naturally , so the idea of ​​the present invention is to set a method to quickly align the center of the graphic area on the screen 8 with the center of the carbon ink graphic to be printed on the ceramic substrate...

Abstract

The invention discloses a center alignment device in a carbon film resistor printing process. The center alignment device comprises a ceramic substrate positioning fixture, a ceramic substrate placedon the ceramic substrate positioning fixture, a screen frame, and a screen fixed in the screen frame. The center alignment device is characterized by further comprising a second rail, a rail trolley and a laser device, wherein two end parts of the second rail are fixedly arranged and in a semicircular shape, the rail trolley is slidably matched with the second rail, the laser device is arranged onthe rail trolley, the middle part of the second rail is positioned above the screen, a beam direction of the laser device is vertically downward, the beam vertically irradiates on the dead center ofa pattern region on the screen, and the center of a carbon printing ink pattern to be printed on the ceramic substrate is adhered with an alignment film printed with a colored pigment. The center alignment device has the beneficial effects that the center alignment device disclosed by the invention can quickly realize the alignment of the pattern region on a screen printing plate and the carbon printing ink pattern to be printed on the ceramic substrate, saves time and labor, and is easy to operate.

Description

technical field [0001] The invention belongs to the field of ceramic substrate circuit board production, and in particular relates to a center alignment device in the process of printing carbon film resistors. Background technique [0002] Printing carbon film resistors on ceramic substrates is a very important process in the production process of ceramic circuit boards. Printing carbon film resistors mainly includes the following steps: adjusting carbon ink to make it reach the required viscosity; The second step: material cutting, that is, after processing the ceramic substrate, install it on the screen printing machine; the third step: make the screen plate, and then install it on the screen printing machine; the fourth step: pre-adjustment, to ensure that the stroke of the scraper can be Cover the graphic area on the screen; the fifth step: alignment adjustment, adjust the relative position of the screen, so that the graphic area on the screen is aligned with the carbon ...
