Description

Photovoltaic silk screen printing screen linewidth measurement calibrating device

Technical Field

The utility model relates to a solar cell production field, in particular to screen printing field.

Background

At present, in the field of photovoltaic cell manufacturing, screen printing is used as the most important process, and the printing effect directly determines the cell conversion efficiency. Especially, the spread of the SE printing process is related to the PT value of the screen printing line. The line width and PT value are accurately controlled to 0.1 micron. The screen inspection process must be precisely controlled and the inspection equipment must be periodically calibrated. The unified calibration piece in the existing market is a glass ruler. Because the screen patterns are in a cross net shape, the glass ruler can not accurately position the line width and the PT value.

Disclosure of Invention

The utility model aims to solve the technical problem that how to provide a photovoltaic silk screen printing plate linewidth measurement calibrating device that can accurate positioning linewidth and PT value.

The utility model adopts the technical proposal that: a photovoltaic silk-screen printing screen line width measurement calibrating device is characterized in that grids and marks which are prepared by a chromium material layer and are consistent with the photovoltaic silk-screen printing screen line pattern are arranged on one surface of a rectangular transparent glass plate, the thickness of the transparent glass plate is 2-4mm, and the thickness of the chromium material layer is 0.5-1 mm.

The mark comprises dimension marks related to measurement of two-dimensional measurement equipment such as main grid and auxiliary grid width, main grid spacing, auxiliary grid spacing, grid overall width and length and the like.

The utility model has the advantages that: after the device is put into operation, the device plays a practical, standard and unified role in measuring and calibrating the line width and PT value of the photovoltaic silk screen printing plate, and forms a fixed standard part for the calibration and exchange of the screen printing plate manufacturing party and the battery using party. The measurement standard is more uniform and accurate.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

A piece of ultra-white light-transmitting glass with the size of 180 x 160 x 5mm is selected. And drawing a CAD graph film (the width and the interval of fixed lines of the film, the graph is composed of 5 main grids and 106 fine grids) according to the current battery 5BB graph and marking. And correspondingly coating a layer of chromium material metal liquid on the glass carrier according to the pattern film and the mark, and drying and solidifying the chromium material metal liquid on the glass carrier.

The application process is as follows

And fixedly placing the manufactured calibration device on a working table of a quadratic element measuring device.

And adjusting the quadratic element measuring equipment to be in 191-time focusing state, and measuring the line width of the device.

The detection process of the screen manufacturing side and the screen for incoming materials at the battery manufacturing end are respectively measured aiming at the device, the two variance distances are the difference of the two devices, the inside of the user side is periodically calibrated and measured, and if the difference between the measured value and the standard value is the fault difference of the device or the difference of the measuring method is considered.

The utility model discloses after the input is used, exchange the standard component that has formed for half tone preparation side and battery user to the standard calibration. The measurement standard is more uniform and accurate.
