Adjustment of alignment deviation during printing
The next step is to introduce how to adjust the deviation in the printing process and explain it to you. First of all, there is an alignment setting on the computer monitor, open the alignment setting, there are left, right, up, down and left and right rotation to adjust the deviation of +- value. Here is a point value, according to the required deviation, size, accuracy and the required range, you can adjust the point value to 0.01 or 0.1, 0.2 can be. If the deviation is very large, more than half a millimeter, then you can set it to 0.1 and move a little bit further each time. When the need for fine tuning is very small when the number is changed to small, the smaller the value of the more accurate tuning, the point value needs to be adjusted according to the needs of printing.
So how to adjust the deviation? This printing machine is CCD alignment table moving type, because there are two types of printing machines, one moving table, one moving stencil, then the two need to adjust the direction is the opposite. If the machine is a table-top moving printing machine, then the printing needs to be compared with the original coordinates, to the right, it needs to be adjusted to the right; to the left, it needs to be adjusted to the left, and so on. Rotation is the same reason, the left side is high, the right side is low, then you need to adjust to the right; that the left side is low, the right side is high to the left to adjust. If the machine is the stencil moving CCD alignment printer, then you need to adjust to the opposite direction; and so on, including the rotation is the same, you can judge the deviation according to the actual situation, and then go to adjust.
Here are a few values, the alignment accuracy is set at 0.1, if the printing deviation requirements are very high, the alignment accuracy can be set relatively high, 0.01 are not relevant; if the printing accuracy requirements are not so high, then you can properly relax the requirements, 0.2, 0.5, 0.1 are not relevant. But according to the actual situation to adjust the value, the smaller the value, the higher the accuracy, the larger the value, the lower the accuracy; the larger the value, the faster the speed, the more accurate the value, then the speed will be a little slower, but it will be very high precision. The number of alignment is set 3 times, and if the alignment is not aligned 3 times, it will automatically alarm. The reason is that the MARK point is defective, sometimes the MARK point is not within the range of the camera, it will do several times to find the point alignment, find the point three times, if it is not aligned, it will automatically alarm. The value is recommended to be adjusted to 3-5 times, and it is easier to find the problem point for improvement first after the alarm, and then go to the alignment printing.
