Technical Field
[0001] This utility model relates to the field of solar cell printing technology, and in particular to a solar cell screen for processing solar cells. Background Technology
[0002] Screen printing is an important step in the production of solar cells. The screen printing process generally uses a solar cell printing screen, which prints the solar cell onto the screen using silver paste through a pre-set pattern area on the screen.
[0003] Solar cells of different specifications have different thicknesses. Traditional solar cell screens can usually only accommodate cells of a specific thickness. Different screens need to be used for cells of different thicknesses, which increases production costs and complexity.
[0004] Therefore, since solar cells of different specifications have different thicknesses, traditional solar cell screens can usually only adapt to cells of a specific thickness. Different screens need to be changed for cells of different thicknesses, which increases production costs and complexity. A solar cell screen for processing solar cells can be designed that can be adjusted according to the thickness of the cells, thereby facilitating the matching of the screen and the cells for printing. Utility Model Content
[0005] To overcome the problem that solar cells of different specifications have different thicknesses, traditional solar cell screens can usually only adapt to cells of a specific thickness. Different screens need to be replaced for cells of different thicknesses, which increases production costs and complexity.
[0006] The technical solution of this utility model is as follows: a solar cell screen for processing solar cells, comprising a screen frame, a screen cloth, a collecting component, a mounting frame, a positioning component, and a cell substrate. The screen cloth is fixedly installed inside the screen frame, and a patterned area is provided on the surface of the screen cloth. The collecting component is located on one side of the screen cloth. The mounting frame is located inside the screen frame, below the screen cloth. An upper wedge is provided inside the mounting frame, and a lower wedge is provided below the upper wedge. The inclined surfaces of the upper and lower wedges correspond to and fit together. An internally threaded fixing plate is fixedly installed on the top of the mounting frame. A threaded rod is provided on one side of the lower wedge, and the threaded rod is rotatably connected to the lower wedge. The threaded rod passes through the internally threaded fixing plate and is threadedly connected to the internally threaded fixing plate. A knob is fixedly installed at one end of the threaded rod. The positioning component is located above the upper wedge, and the cell substrate is located inside the positioning component.
[0007] Preferably, the upper and lower wedges are supported and installed using an installation frame. The upper wedge supports and places the battery cell substrate, and the positioning component positions the battery cell substrate supported by the upper wedge. By rotating a threaded rod with a knob, the threaded rod engages with an internal threaded fixing plate, which moves the lower wedge. When the lower wedge moves, the inclined surfaces of the upper and lower wedges correspond and fit together, causing the upper wedge to rise and fall, thereby adjusting the distance between the battery cell substrate placed above the upper wedge and the mesh. This allows for the adaptation to battery cell substrates of different thicknesses within a certain range. Different meshes do not need to be replaced for battery cell substrates of different thicknesses, effectively reducing costs and improving efficiency.
[0008] Preferably, an adhesive layer is provided on the top of the mesh fabric, and the surface of the adhesive layer has a cutout portion that corresponds to the patterned area on the surface of the mesh fabric.
[0009] Preferably, the mesh frame has a groove inside, the two sides of the mounting frame are located inside the groove, the mounting frame is slidably connected to the groove, and a positioning pad is fixedly installed inside the mesh frame, with the positioning pad located on one side of the mounting frame.
[0010] Preferably, the collecting component includes a through groove, an inclined portion, and a mounting cavity. The mounting cavity is provided inside the mesh frame, and the through groove is provided on the inner wall of the mesh frame. The through groove communicates with the mounting cavity, and the inclined portion is provided on the lower surface of the through groove.
[0011] Preferably, the collection component includes a collection box and a handle. The collection box is disposed inside the mounting cavity and is slidably connected to the mounting cavity. A handle is fixedly installed at one end of the collection box.
[0012] Preferably, two sets of first guide rails are fixedly installed on the side wall inside the mounting frame. The first guide rails pass through the upper wedge block and are slidably connected to the upper wedge block. Two sets of second guide rails are fixedly installed on the bottom surface inside the mounting frame. The second guide rails pass through the lower wedge block and are slidably connected to the lower wedge block.
[0013] Preferably, the positioning component includes a first positioning strip and a second positioning strip. Both the first positioning strip and the second positioning strip are fixedly installed above the upper wedge block. There are two sets of the first positioning strip and the second positioning strip. The two sets of the first positioning strip are arranged symmetrically, and the two sets of the second positioning strip are arranged symmetrically. The battery cell substrate is located between the two sets of the first positioning strip and the two sets of the second positioning strip.
[0014] The beneficial effects of this utility model are:
[0015] 1. By rotating the threaded rod with the knob, the threaded rod engages with the internal threaded fixing plate, which can push the lower wedge block to move. When the lower wedge block moves, since the inclined surfaces of the upper and lower wedge blocks correspond to and fit together, the upper wedge block can be driven to rise and fall, thereby adjusting the distance between the battery cell substrate placed above the upper wedge block and the mesh. It can adapt to battery cell substrates of different thicknesses within a certain range, making it more versatile. There is no need to replace the entire mesh, saving costs and improving efficiency.
[0016] 2. During printing, insert the collection box into the installation cavity. When the squeegee scrapes to one end of the mesh, the excess silver paste will pass through the groove and be guided into the collection box by the inclined part. After the collection box collects a certain amount of silver paste, it can be pulled out by the handle to recycle the silver paste, effectively saving costs. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 and Figure 2This utility model provides an embodiment: a solar cell screen for processing solar cells, comprising a screen frame 1, a screen cloth 2, a collecting component, a mounting frame 5, a positioning component, and a solar cell substrate 7. The screen cloth 2 is fixedly installed inside the screen frame 1, and a patterned area 201 is provided on the surface of the screen cloth 2. The collecting component is disposed on one side of the screen cloth 2. The mounting frame 5 is disposed inside the screen frame 1, located below the screen cloth 2. An upper wedge 501 is disposed inside the mounting frame 5, and a lower wedge 502 is disposed below the upper wedge 501. The inclined surfaces of the upper wedge 501 and the lower wedge 502 correspond to each other and fit together. An internally threaded fixing plate 503 is fixedly installed on the top of the mounting frame 5. A threaded rod 504 is provided on one side of the lower wedge 502, and the threaded rod 504 is rotatably connected to the lower wedge 502. The threaded rod 504 passes through the internally threaded fixing plate 503 and is threadedly connected to the internally threaded fixing plate 503. A knob 5 is fixedly installed at one end of the threaded rod 504. 05. The positioning component is located above the upper wedge 501, and the battery cell substrate 7 is located inside the positioning component. The upper wedge 501 and the lower wedge 502 are supported and installed by the mounting frame 5. The upper wedge 501 can support and place the battery cell substrate 7, and the positioning component can position the battery cell substrate 7 supported by the upper wedge 501. By rotating the threaded rod 504 with the knob 505, the threaded rod 504 engages with the internal threaded fixing plate 503, which can push the lower wedge 502 to move. When the lower wedge 502 moves, since the inclined surfaces of the upper wedge 501 and the lower wedge 502 correspond to and fit together, the upper wedge 501 can be driven to rise and fall, thereby adjusting the distance between the battery cell substrate 7 placed above the upper wedge 501 and the mesh 2. Within a certain range, it can adapt to battery cell substrates 7 of different thicknesses. For battery cell substrates 7 of different thicknesses, there is no need to change different meshes, which can effectively reduce costs and improve efficiency.
[0024] Please see Figure 2 and Figure 3In this embodiment, an adhesive layer 3 is provided on the top of the mesh fabric 2. The surface of the adhesive layer 3 has a cutout portion 301, which corresponds to the pattern area 201 on the surface of the mesh fabric 2. The adhesive layer 3 covers the surface of the mesh fabric 2, and the cutout portion 301 ensures that the pattern area 201 is printed normally. A sliding groove 101 is provided inside the frame 1. The two sides of the mounting frame 5 are located inside the sliding groove 101, and the mounting frame 5 is slidably connected to the sliding groove 101. A positioning pad 102 is fixedly installed inside the frame 1, and the positioning pad 102 is located on one side of the mounting frame 5. The sliding groove 101 facilitates the stable sliding of the mounting frame 5 inside the frame 1, so that the mounting frame 5 can be easily taken out or put back into the frame 1, which is convenient for picking up and putting in the battery cell substrate 7. The positioning pad 102 can limit one end of the mounting frame 5 when the mounting frame 5 is installed into the frame 1, and at the same time prevent the mounting frame from being inserted into the frame 1. When the frame 5 is inserted, it makes rigid contact with the inner wall of the screen frame 1, protecting the screen frame 1 and the mounting frame 5. The collection component includes a through groove 401, an inclined part 402, and a mounting cavity 403. The mounting cavity 403 is provided inside the screen frame 1, and the through groove 401 is provided on the inner wall of the screen frame 1. The through groove 401 communicates with the mounting cavity 403, and the inclined part 402 is provided on the lower surface of the through groove 401. The collection component includes a collection box 404 and a handle 405. The collection box 404 is located inside the mounting cavity 403 and is slidably connected to the mounting cavity 403. The handle 405 is fixedly installed at one end of the collection box 404. The handle 405 allows the collection box 404 to be easily placed into or removed from the mounting cavity 403. During printing, the through groove 401 can scrape excess silver paste from the surface of the screen fabric 2 into the collection box 404 for recycling. The inclined part can guide the silver paste into the collection box 404.
[0025] Please see Figure 4In this embodiment, two sets of first guide rails 506 are fixedly installed on the side wall inside the mounting frame 5. The first guide rails 506 pass through the upper wedge 501, and the upper wedge 501 is slidably connected to the first guide rails 506. Two sets of second guide rails 507 are fixedly installed on the bottom surface inside the mounting frame 5. The second guide rails 507 pass through the lower wedge 502, and the lower wedge 502 is slidably connected to the second guide rails 507. By setting the first guide rails 506, the lifting and lowering of the upper wedge 501 can be guided to ensure the accurate positioning of the battery cell substrate 7. By setting the second guide rails 507, the movement of the lower wedge 502 can be guided to ensure the accurate positioning of the lower wedge 501. 2. Stable movement, thus ensuring the stable movement of the upper wedge 501; the positioning component includes a first positioning strip 601 and a second positioning strip 602. The first positioning strip 601 and the second positioning strip 602 are both fixedly installed above the upper wedge 501. There are two sets of the first positioning strip 601 and the second positioning strip. The two sets of first positioning strips 601 are symmetrically arranged, and the two sets of second positioning strips 602 are symmetrically arranged. The battery cell substrate 7 is located between the two sets of first positioning strips 601 and the two sets of second positioning strips 602. By setting the two sets of first positioning strips 601 and the two sets of second positioning strips 602, the battery cell substrate 7 can be surrounded and positioned.
[0026] When working, pull the threaded rod 504 to make the mounting frame 5 slide along the slide groove 101, pull the mounting frame 5 out from the inside of the mesh frame 1, place the battery cell substrate 7 above the upper wedge block 501, and use the cooperation of the first positioning strip 601 and the second positioning strip 602 for positioning.
[0027] After the battery cell substrate 7 is placed, the mounting frame 5 is pushed back into the mesh frame 1 along the slide groove 101. The positioning pad 102 is used to position the pushed-back mounting frame 5, and at the same time prevents the mounting frame 5 from rigidly contacting the inner wall of the mesh frame 1 when it is inserted, thus protecting the mesh frame 1 and the mounting frame 5.
[0028] Rotating the threaded rod 504 with the knob 505 engages with the internal threaded fixing plate 503, which can push the lower wedge 502 to move. When the lower wedge 502 moves, since the inclined surfaces of the upper wedge 501 and the lower wedge 502 correspond to and fit together, the upper wedge 501 can be raised and lowered, thereby adjusting the distance between the battery cell substrate 7 placed above the upper wedge 501 and the mesh 2. It can adapt to battery cell substrates 7 of different thicknesses within a certain range, making it more versatile. It does not require replacing the entire mesh, saving costs and improving efficiency.
[0029] During printing, the collection box 404 is inserted into the mounting cavity 403, and printing silver paste is applied to the top of the screen fabric 2. The silver paste is scraped on the top of the screen fabric 2 using a squeegee for screen printing. The pattern layer on the surface of the screen fabric 2 is used to print the battery substrate 7 below. When the squeegee reaches one end of the screen fabric 2, the excess silver paste will pass through the through groove 401 and be guided by the inclined part 402 into the collection box 404. After the collection box 404 collects a certain amount of silver paste, the collection box 404 can be pulled out using the handle 405 to recycle the silver paste, effectively saving costs.
[0030] After the battery cell substrate 7 is printed, simply remove the mounting frame 5, replace it with a new battery cell substrate 7, and repeat the above steps.
[0031] Through the above steps, the upper wedge 501 can support and place the solar cell substrate 7. By rotating the threaded rod 504 with the knob 505, the threaded rod 504 engages with the internal threaded fixing plate 503, which can push the lower wedge 502 to move. When the lower wedge 502 moves, since the inclined surfaces of the upper wedge 501 and the lower wedge 502 correspond to and fit together, the upper wedge 501 can be driven to rise and fall, thereby adjusting the distance between the solar cell substrate 7 placed above the upper wedge 501 and the mesh 2. Within a certain range, it can adapt to solar cell substrates 7 of different thicknesses. For solar cell substrates 7 of different thicknesses, there is no need to change different meshes, which can effectively reduce costs and improve efficiency. This solves the problem that solar cells of different specifications have different thicknesses. Traditional solar cell meshes can usually only adapt to solar cells of a specific thickness. For solar cells of different thicknesses, different meshes need to be changed, which increases production costs and complexity.
[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
