As cell manufacturers in the photovoltaic industry have higher and higher requirements for the quality of cell production, problems encountered in the production process are emerging one after another. In order to enable cell manufacturers to better solve the quality problems of photovoltaic cells and understand the importance of quality, the Automatic Image Measuring Instrument developed by "Millennial Solar" is equipped with a measurement system based on high-resolution cameras, which can help photovoltaic enterprise users improve screen printing process. "Millennial Solar" will introduce the grid data measurement of the Automatic Image Measuring Instrument!

Measuring Technology-Exclusive R&D

Millennial Automatic Image Measuring Instrument can calculate a large amount of measurement data by performing a preset operation on the solar cells, so as to complete high-precision cover scanning.

Millennial Automatic Image Measuring Instrument has the exclusive VMM PRO metal coverage technology, which can help cell manufacturers to produce better grid electrodes, improve the screen printing process, reduce the shading area, and accurately calculate the data of grid lines of photovoltaic cells , thereby improving the efficiency of photovoltaic cells.

The Grid Width Measurement Guarantees the Qualification of the Process

The grid line width measurement can accurately calculate the grid line width, and measure whether the grid line in the whole solar cell is consistent with the grid line of the photovoltaic grid according to the width of a single grid line, so as to ensure the efficiency of conductivity.

You can place the solar cell on the upper left corner of the measurement whiteboard first, turn on the main lens, find the position of the grid line, and switch to 4 times the pixel, adjust the brightness and focus with the lens, and place the grid line in the middle of the interface. Click the function of measuring a straight line in a rectangular frame, use the left mouse button to select the first point on the left line, and press and hold down. Grab another line on the right side, and the operation is the same as above. After grid line 1 and grid line 2 are selected, click the function of constructing a straight line to automatically measure the width of the grid line of the photovoltaic cell.

Grid Line Distance Measurement - Easy to Compare With Stencil, Easy to Operate

In order to ensure the conductive efficiency of the photovoltaic cell, ensure whether it meets the manufacturing process standards, and then compare it with the grid plate, it is necessary to measure the distance of the grid line of the photovoltaic cell.

There are similarities between the grid distance measurement and the grid line width measurement. You can first grab the left side of the first grid line as grid line 3, and grab the left side of the second grid line as grid line 4, and then select the grid line 3 and grid line 4, click the function of constructing a straight line to automatically calculate the distance between grid lines of photovoltaic cells.

Mark Point Measurement - Saving a Lot of Operating Time

In order to make the measurement operation more convenient, the mark point of the photovoltaic cell can be preset, and the measurement can be automatically scanned according to the preset coordinate position, thereby helping the battery manufacturer to save operation time.

When measuring the mark point, you need to adjust the lens to the 4 magnification and aim at the position of the mark point, select the circle frame measurement circle function in the measurement mode, and then click the outer black line frame of the mark point twice in the system software. And make the green circle on the black line frame coincide with the black line frame.

Press the left button of the mouse to display a blue circle, then double-click between the two blue circles to display a red circle, select the blue circle and the red circle, and click the function of constructing a straight line to automatically measure the center of the mark point Distance, so as to calculate the data of the mark point.
