Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic material processing, and in particular to a high-speed and high-efficiency full-color photoelectric functional material coloring device. Background Art

[0002] Full-color optoelectronic functional materials are materials that can emit light waves of multiple colors. These materials are usually composed of semiconductor nanocrystals or quantum dots. By controlling their size and composition, different colors of light can be emitted. When processing full-color optoelectronic functional materials, color forming operations are required. Through color forming operations, full-color optoelectronic functional materials can show more vivid and rich colors. This is crucial for display technology because the richness and accuracy of colors directly affect the quality of display effects.

[0003] Screen printing is often used for coloring materials. Screen printing can only produce single-color blocks, and cannot produce multi-color patterns or full-color optoelectronic functional materials.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] like Figure 1 - Figure 4 As shown, a high-speed and efficient full-color optoelectronic functional material coloring equipment includes a workbench 1, and the upper sides of the left and right ends of the workbench 1 are fixedly connected with fixed plates 3, the upper side of the workbench 1 is provided with a conveyor belt 2, the outer sides of the left and right fixed plates 3 are fixedly connected with side plates 4, and a spraying unit 5 is provided between the left and right side plates 4.

[0036] The spraying unit 5 includes a plurality of connecting tubes 501, which are fixedly connected between the left and right side panels 4. A plurality of nozzles 502 are fixedly connected to the lower side of the connecting tube 501. Two fixed blocks 503 are fixedly connected to the rear side of the connecting tube 501. A curing LED lamp 504 is fixedly connected between the two fixed blocks 503. There are ten connecting tubes 501 and ten curing LED lamps 504, and twelve nozzles 502. The curing LED lamp 504 has a length of 1250 mm and a wavelength of 395 nm.

[0037] A total of 120 nozzles 502 are used, with 12 nozzles in each row, and a printing width of 1200mm, covering the standard component size width on the market, and reserved positions for nozzles 502, ink supply system and circuit board. The nozzles 502 are fixed in position and the material is fed forward by transmission. The fixed nozzle 502 can reduce the lateral cumulative error.

[0038] There are 12 nozzles 502 for each color (the color can be selected according to the process of full-color optoelectronic functional materials). 30PL is used for varnish and white, and 3PL is used for color. The reason is that varnish is used for bonding or protection, and does not require high precision, but requires a certain thickness, so 30PL is used. Because white reflects all light, the aperture of the nozzle 502 of white ink is large, which can allow more light to enter. Color is for the bright and high-precision requirements of the picture, and can absorb light of the corresponding color. The nozzle 502 of the color ink has a small aperture. The spraying method adopts full-color micro-layer technology, with high light transmittance and consistent color.

[0039] There are two types of varnish: front and back (the nozzles 502 on the connecting tubes 501 on both sides spray varnish). Varnish bonding is suitable for room temperature packaging. It only needs printing and does not need curing. Taking a 2278*1134mm component as an example, it only takes 10 seconds to complete the spraying of the entire picture. Converted into square meters, it is 900 square meters per hour, and the daily production capacity easily exceeds 10,000 square meters, far exceeding all full-color optoelectronic functional material spraying equipment on the market. Varnish protection is to add a layer of transparent protective ink on the surface of the component after other colors are sprayed.

[0040] White is also designed with two rows. The reason is that the method of direct spraying components is to first apply white and then color. White is the base to show the color. If it is a material that needs to be laminated, such as glass or film, this material needs to be mirrored. It must be colored first and then white. In order to meet various needs, a two-row design is made. All inks are environmentally friendly inks, do not contain VOC, and have ROSH reports.

[0041] The control system and ink supply system are arranged outside the device to control the operation of the printing system and the curing system, including the printing sequence, the selection of the nozzle 502 and the curing time. The control system can also be adaptively adjusted according to the size and shape of the photovoltaic module to meet different needs.

[0042] The ink supply system provides a stable and uniform supply of ink to the nozzle 502. Through precise metering and adjustment, the ink supply system ensures that the nozzle 502 always obtains sufficient ink during the printing process, ensuring the printing quality and stability.

[0043] Embodiment 2:

[0044] Based on the first embodiment, Figure 5 - Figure 7As shown, the deviation correction unit 6 includes a U-shaped plate 601, which is fixedly connected to the outer sides of the fixed plates 3 on the left and right sides. A control rod 602 is arranged on the outer side of the U-shaped plate 601, one end of the control rod 602 passes through the outer side of the U-shaped plate 601 and is fixedly connected to the deviation correction plate 604, and the other end of the control rod 602 is fixedly connected to the moving plate 603. The lower side of the workbench 1 is fixedly connected to two air boxes 1 608 and air boxes 2 609, and the inner sides of the two air boxes 1 608 are both provided with a piston plate 1 620, and the piston The outer side of the plate 1 620 is fixedly connected with a moving rod 607, the outer end of the moving rod 607 passes through the outer side of the air box 1 608 and is fixedly connected with a control block 606, an L-shaped block 605 is fixedly connected between the control block 606 and the moving plate 603, a U-shaped tube 621 is fixedly connected between the two air boxes 1 608, a delivery tube 622 is fixedly connected between the U-shaped tube 621 and the air box 2 609, an electric push rod 2 624 is fixedly connected to the inner side of the air box 2 609, and the outer end of the electric push rod 2 624 is fixedly connected to There is a piston plate 623, a piston plate 620 and a moving rod 607 are all slidably connected to the air box 608, and the piston plate 623 is slidably connected to the air box 609. When the material is inkjetted, the material is first placed on the conveyor belt 2, and then the electric push rod 624 is controlled to drive the piston plate 623 to move backward, and through the conveying pipe 622 and the U-shaped tube 621, the gas in the two air boxes 608 is extracted into the air box 609. Under the action of air pressure, the piston plate 620 moves, and the two sides The piston plates 620 are brought close to each other, so that the piston plate 620 drives the moving rod 607 to move, the moving rod 607 drives the control block 606 to move, the control block 606 drives the L-shaped block 605 to move, the L-shaped block 605 drives the moving plate 603 to move, the moving plate 603 drives the control rod 602 to move, and the control rod 602 drives the correcting plate 604 to move, so that the correcting plates 604 on the left and right sides are brought close to each other, so that the correcting plates 604 on both sides can correct the material on the conveyor belt 2 to avoid deviation during material transmission.

[0045] The upper and lower sides of the left and right side deviation correcting plates 604 are fixedly connected with vertical plates 610, and the outer sides of the upper and lower side vertical plates 610 are provided with lifting grooves 611, and the inner sides of the upper and lower side lifting grooves 611 are slidably connected with lifting blocks 612, one side of the lifting block 612 is rotatably connected with a rotating rod 613, and the outer side of the rotating rod 613 is fixedly connected with an adjusting roller 614, and the other side of the lifting block 612 is fixedly connected with a connecting block 1 615, and the outer sides of the upper and lower side connecting blocks 1 615 are rotatably connected with connecting plates 616, and the outer side of the connecting plate 616 is rotatably connected with a connecting block 2 617, and the outer side of the connecting block 2 617 is fixedly connected with a moving block 618. An electric push rod 619 is fixedly connected between the moving block 618 and the correcting plate 604, and the connecting plate 616 is set as an inclined structure. When feeding, the electric push rod 619 is controlled, and the electric push rod 619 drives the moving block 618 to move, and the moving block 618 drives the connecting plate 616 to rotate. Since the two connecting plates 616 are set as an inclined symmetrical structure, the connecting plate 616 drives the lifting block 612 to move, and the lifting block 612 drives the adjusting roller 614 on the rotating rod 613 to move, so that the adjusting rollers 614 on both sides are close to each other, so that the adjusting rollers 614 on both sides limit the upper and lower sides of the feeding material, thereby increasing the stability of transmission.
