Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic design, and in particular to a method for automatic typesetting of a photovoltaic silk-screen printing screen. Background Art

[0002] Screen printing technology is to use photosensitive materials to make screen printing plates through photoengraving. Even if the screen holes of the image part of the screen are through holes, the screen holes of the non-image part are blocked. When printing, the ink or paste is transferred to the substrate through the mesh holes of the image part through the extrusion of the scraper, forming the same image as the original.

[0003] In the field of electrode printing of photovoltaic cells, there are grid lines on the pattern to be laid out, and their width is close to the diameter of the steel wire on the mesh. In order to avoid the overlap of the grid lines and the steel wires and the inability to form through holes, it is necessary to align the drawing and the mesh through layout so that the grid lines avoid the steel wires.

[0004] In order to improve the success rate of typesetting, some steel wires will be removed from the uniformly woven steel wire mesh to form a non-uniform drawn area. The wire spacing at both ends of the drawn area becomes larger, and the risk of the grid lines being pressed is reduced.

[0005] The width of the drawn area is usually only about 0.1 mm. In the prior art, photovoltaic screen printing stencil layout is achieved by manually making the drawings into films, and then observing the overlap between the films and the mesh under a microscope to check the layout.

[0006] Problems with the existing technology: 1) Typesetting requires processing film, which increases material consumption costs. 2) It is difficult for manual operation to be stable and batch operated, resulting in low typesetting efficiency. Summary of the invention

[0007] In view of this, it is necessary to provide a method, device, electronic equipment and medium for automatic typesetting of photovoltaic silk-screen printing screens, so as to solve the problem of low efficiency caused by manual typesetting of photovoltaic silk-screen printing screens.

[0008] In order to solve the above problems, the present invention provides a method for automatic typesetting of photovoltaic screen printing stencils, comprising:

[0009] Photographing the photovoltaic silk screen fabric in slices based on the size of the pattern to be typeset, and obtaining slice photos of the photovoltaic silk screen fabric after the slices;

[0010] Slicing the pattern to be typeset so that the pattern to be typeset after slicing corresponds to the sliced ​​photovoltaic silk-screen mesh photos after slicing;

[0011] Comparing each slice in the pattern to be typeset with its corresponding photovoltaic screen printing mesh slice photo one by one, to obtain the pressure line adjustment range of each slice in the pattern to be typeset;

[0012] Taking the intersection of the pressure adjustment ranges of all the slices of the pattern to be typeset, to obtain the overall pressure adjustment range of the pattern to be typeset;

[0013] The patterns to be typeset are typeset based on the overall pressure line adjustment range of all the patterns to be typeset.

[0014] In some possible implementations, the pattern to be typeset is sliced ​​so that the sliced ​​pattern to be typeset corresponds to the sliced ​​photovoltaic silk screen fabric sliced ​​photos after the slices, including:

[0015] Aligning the pattern to be typeset with the photovoltaic silk-screen mesh based on preset reference points on the photovoltaic silk-screen mesh;

[0016] The pattern to be typeset is cut using the slice horizontal and vertical spacing and slice size of the photovoltaic silk screen cloth slice photo to obtain the pattern slice to be typeset.

[0017] In some possible implementations, the pressure line adjustment range is used to ensure that the grid lines in each slice in the pattern to be typeset are within the drawing area in the corresponding photovoltaic silk screen mesh slice photo, and the pressure line adjustment range of each slice in the pattern to be typeset is obtained by comparing each slice in the pattern to be typeset with its corresponding photovoltaic silk screen mesh slice photo one by one, including:

[0018] Each slice in the pattern to be typeset is matched with the photovoltaic screen printing mesh slice photo according to row and column numbers;

[0019] The line pressure adjustment range of each slice is the intersection of the line pressure adjustment ranges of each grid line in the slice.

[0020] In some possible implementations, the preset reference point includes a center point of the photovoltaic silk-screen mesh.

[0021] In some possible implementations, the pressure line adjustment range includes a translation adjustment range and a rotation adjustment range.

[0022] In some possible implementations, the translation adjustment range is between a first distance and a second distance, the first distance being the distance between the grid line and the steel wire above its corresponding drawing area, and the second distance being the distance between the grid line and the steel wire below its corresponding drawing area.

[0023] In some possible implementations, the intersection of the pressure line adjustment ranges of all the slices of the pattern to be typeset includes a first intersection and a second intersection, the first intersection being obtained by taking the intersection of the translation adjustment ranges of the pressure line adjustment ranges of all the slices of the pattern to be typeset; the second intersection being obtained by taking the intersection of the rotation adjustment ranges of the pressure line adjustment ranges of all the slices of the pattern to be typeset.

[0024] The beneficial effect of adopting the above embodiment is: the method for automatic typesetting of a photovoltaic silk screen screen provided by the present invention firstly photographs the photovoltaic silk screen cloth in slices based on the size of the pattern to be typeset, obtains the sliced ​​photos of the photovoltaic silk screen cloth after the slices, further slices the pattern to be typeset so that the pattern to be typeset after the slices corresponds to the sliced ​​photos of the photovoltaic silk screen cloth after the slices, further compares each slice in the pattern to be typeset with its corresponding sliced ​​photos of the photovoltaic silk screen cloth one by one, obtains the pressure adjustment range of each slice in the pattern to be typeset, further takes the intersection of the pressure adjustment ranges of all the slices of the pattern to be typeset, obtains the overall pressure adjustment range of the pattern to be typeset, and finally typesets the pattern to be typeset based on the overall pressure adjustment range of all the patterns to be typeset. The present invention improves the efficiency of photovoltaic silk screen screen typesetting by making one-to-one correspondence between the sliced ​​photos of the photovoltaic silk screen cloth and the pattern to be typeset and slices them, and determines the pressure adjustment range according to the target pressure adjustment range of all the slices of the pattern to be typeset.
