Description

Technical Field

[0001] This application relates to the field of photovoltaic cell production equipment technology, specifically to a screen printing device and a cell printing equipment. Background Technology

[0002] For gridless solar cells, a common stringing process is as follows: First, thermosetting adhesive dots are printed onto the solar cells using a screen printing device. Then, the solar cells with thermosetting adhesive dots and the solder ribbons are laid and stacked according to the stringing rules of the solar cells. The stacked solar cells and solder ribbons are heated to cure the thermosetting adhesive and bond the solder ribbons to the solar cells to form a solar cell string.

[0003] When printing adhesive onto solar cells using a screen printing device, the screen is placed close to the cells to ensure that the thermosetting adhesive on the screen can pass through the screen and be printed onto the cells by the action of the squeegee. In one production scenario, the incoming solar cells to be printed are obtained through dicing and high-temperature drying. The cells are at a high temperature, so when the screen is close to the cells for printing, the heat from the cells is conducted to the screen. After a certain period of continuous printing, the screen will heat up due to heat accumulation. Since thermosetting adhesives are sensitive to temperature, the increased temperature of the screen will change the viscosity and other properties of the adhesive, thus affecting the printing quality of the solar cells. Utility Model Content

[0004] Therefore, the technical problem to be solved by this application is to overcome the defect that the thermosetting adhesive on the existing screen printing device receives heat from the battery cell, causing its properties to change and ultimately affecting the printing quality of the battery cell.

[0005] Therefore, this application provides a screen printing apparatus, comprising:

[0006] Support frame;

[0007] A mounting plate is installed on a support frame. The mounting plate is used to fix the screen. A hollow area is formed in the middle of the mounting plate to expose the screen from above. The screen is used to hold the thermosetting adhesive.

[0008] A cooling assembly, mounted on a support frame and / or mounting plate, is configured to blow cool air toward the screen exposed to the cutout area to cool the thermosetting adhesive on the screen.

[0009] The screen printing apparatus provided in this application, by setting a cooling component on a support frame or mounting plate, can deliver cold air provided by an external cold air source to the screen, thereby cooling the screen and preventing it from heating up due to heat accumulation, thus maintaining a stable temperature. This ensures that the adhesive properties of the thermosetting adhesive on the screen do not change, and also ensures that the printing quality of the battery cells is not affected.

[0010] Optionally, the cooling assembly includes an air duct positioned above the mounting plate. The air duct has an air inlet and at least one air outlet facing the screen. The air inlet of the air duct is connected to an external cold air source, and the cold air supplied by the cold air source is delivered to the screen through the air outlet; or...

[0011] The cooling assembly includes at least one air blowing block, which is mounted on or near the mounting plate. The air blowing block has an air chamber inside, and the air inlet of the air chamber is connected to an external cold air source. The side wall of the air blowing block facing the hollow area has an air blowing port connected to the air chamber. The cold air provided by the cold air source is blown onto the screen through the air blowing port.

[0012] Two simple implementation methods for cooling components are provided. By setting an air duct or air blowing block above the mounting plate and connecting it to an external cold air source, the cold air provided by the external cold air source can be quickly blown onto the screen.

[0013] Optionally, the cooling assembly includes an air duct and at least one air blowing block, wherein:

[0014] The air duct is located above the mounting plate. The air duct has an air inlet and at least one air outlet. The air inlet of the air duct is connected to an external cold air source.

[0015] The air blowing block is installed on or near the mounting plate. The air blowing block has an air chamber inside, and the air inlet of the air chamber is connected to an air outlet of the air guide pipe through a connecting pipe. The side wall of the air blowing block facing the hollow area has an air blowing port that is connected to the air chamber. The air blowing port is used to blow cold air onto the screen.

[0016] Another method for implementing the cooling component is provided, which involves simultaneously setting up air ducts and air blowing blocks so that the air ducts and air blowing blocks can work together to blow the cold air provided by the external cold air source onto the screen.

[0017] Optionally, two air-blowing blocks are provided, and the two air-blowing blocks are arranged opposite each other on both sides of the hollowed-out area; or,

[0018] There are four air-blowing blocks, which are arranged in pairs around the perimeter of the hollow area.

[0019] By setting two or four air blowing blocks and placing them opposite each other on the periphery of the screen's cutout area, each air blowing block can simultaneously cool the screen from different directions, thereby improving the uniformity of cooling.

[0020] Optionally, the air inlet is tilted downwards, and the cold air is blown diagonally downwards onto the screen through the air inlet.

[0021] By setting the air outlet to be tilted downwards, cold air can be blown diagonally downwards onto the screen, thereby cooling the screen and the thermosetting adhesive on it. Furthermore, because the air outlet is tilted downwards, the cold air can maintain a stable blowing direction under the action of gravity after being blown out, allowing more cold air to reach the screen and thus improving the cooling efficiency.

[0022] Optionally, the number of air outlets in the air duct is the same as the number of air blowing blocks, and the air outlets are connected one-to-one with the air inlets of the air blowing blocks; or,

[0023] The number of air outlets in the air duct is greater than the number of air blowing blocks. The air inlet of each air blowing block is connected to one air outlet, and the remaining air outlets are set facing the screen and higher than the air blowing blocks, so as to deliver cold air directly to the screen from above.

[0024] By setting the number of air outlets in the air duct to be equal to the number of air blowing blocks, the cooling component blows cold air only near the screen through the air blowing blocks, thereby cooling the area near the screen and preventing thermosetting adhesive from deteriorating. By setting the number of air outlets in the air duct to be greater than the number of air blowing blocks, the cooling component can blow cold air not only near the screen through the air blowing blocks, but also above the screen through the air duct, thereby cooling a larger area above the screen and improving the cooling effect on the screen.

[0025] Optionally, the screen printing device also includes a housing, which is fixed relative to the mounting plate, has an open bottom, and covers the top of the mounting plate. The housing is used to restrict the outward dissipation of cold air blown out by the cooling components.

[0026] By installing a cover on the screen printing device, specifically a cover that is fixed relative to the mounting plate and has an open bottom, the cover can be placed over the mounting plate, thus forming a relatively sealed space between the cover and the mounting plate. In this way, when cold air supplied by an external cold air source blows towards the screen, the cover can confine the cold air within the sealed space formed by the cover and the mounting plate, thereby preventing the cold air from escaping and improving the cooling effect on the screen.

[0027] Optionally, the screen printing device further includes a lifting drive assembly, which includes a lifting drive unit and a lifting unit. The lifting drive unit is mounted on a support frame. The lifting unit is slidably connected to the support frame and connected to the drive end of the lifting drive unit. The mounting plate is fixedly connected to the lifting unit.

[0028] By setting up a lifting drive assembly, which specifically includes a lifting drive unit and a lifting unit, and a mounting plate fixedly connected to the lifting unit, the lifting unit can drive the mounting plate to move up and down under the drive of the lifting drive unit, thereby adjusting the position of the screen to make the screen closer to or further away from the battery cell to be printed.

[0029] Optionally, the screen printing apparatus also includes a squeegee assembly and a translation drive unit. The squeegee assembly is disposed above the screen and is connected to the drive end of the translation drive unit. The translation drive unit is used to drive the squeegee assembly to move within the cutout area to scrape the thermosetting adhesive on the screen.

[0030] By setting a squeegee assembly and a translation drive unit on the screen printing device, the squeegee assembly can be driven by the translation drive unit to move in the cutout area above the screen to scrape the thermosetting adhesive on the screen, thereby achieving the printing of adhesive onto the battery cell.

[0031] In another aspect, this application also provides a battery cell printing device, which includes the aforementioned screen printing device and a carrier platform. The carrier platform is disposed below the mounting plate of the screen printing device and is used to support the battery cell. The screen printing device is used to print thermosetting adhesive dots onto the battery cell on the carrier platform.

[0032] By setting up the screen printing device and the carrier platform as described above, wherein the carrier platform is located below the mounting plate of the screen printing device and the carrier platform is capable of supporting the battery cell, the screen printing device can print thermosetting adhesive dots onto the battery cell on the carrier platform when the battery cell is supported on the carrier platform. Since the screen printing device is the aforementioned screen printing device, the heat emitted by the battery cell will be neutralized by the cold air in the screen printing device, so as not to affect the characteristics of the thermosetting adhesive on the screen, and thus not to affect the printing quality of the battery cell.

[0046] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0050] This application provides a screen printing device 10, such as... Figures 1 to 6 As shown, the device includes a support frame 1, a mounting plate 2, and a cooling assembly 5. The mounting plate 2 is mounted on the support frame 1 and is used to fix the screen 3. A hollow area 31 is formed in the middle of the mounting plate 2, exposing the screen 3 from above. The screen 3 is used to hold the thermosetting adhesive. The cooling assembly 5 is disposed on the support frame 1 and / or the mounting plate 2. The cooling assembly 5 is configured to blow cold air toward the screen 3 exposed in the hollow area 31 to cool the thermosetting adhesive on the screen 3.

[0051] By setting a mounting plate 2 and a cooling component 5 on a support frame 1, the mounting plate 2 can fix the screen 3, thereby mounting the screen 3 onto the support frame 1. A hollow area 31 is formed in the middle of the mounting plate 2, so that the mounting plate 2 can expose the screen 3 from above through the hollow area 31. The screen 3 can bear the thermosetting adhesive, so that the thermosetting adhesive can be exposed in the hollow area 31. The cooling component 5 is specifically set on the support frame 1. At the same time, the cooling component 5 is also configured to blow cold air toward the screen 3 exposed in the hollow area 31, so that the screen 3 and the thermosetting adhesive on the screen 3 can be cooled by the cold air blown toward the screen 3 by the cooling component 5. When printing adhesive on the battery cell, the heat conducted from the battery cell to the screen 3 will be cooled by the cold air blown toward the screen 3 by the cooling component 5, so that the screen 3 will not heat up due to heat accumulation, but will maintain a stable temperature. This ensures that the adhesive properties of the thermosetting adhesive on the screen 3 will not change, and the printing quality of the battery cell will not be affected.

[0052] In other alternative embodiments, the cooling component 5 can also be disposed on the mounting plate 2, since the cooling component 5 disposed on the mounting plate 2 can also ensure that the cooling component 5 blows cold air toward the screen 3 and cools the screen 3 and the thermosetting adhesive on the screen 3 by means of the cold air.

[0053] Optional, such as Figure 2As shown, the cooling assembly 5 includes an air duct 51, which is disposed above the mounting plate 2. The air duct 51 has an air inlet 511 and at least one air outlet 512 facing the screen 3. The air inlet 511 of the air duct 51 is connected to an external cold air source, and the cold air provided by the cold air source is delivered to the screen 3 through the air outlet 512.

[0054] The screen printing device 10 with the above-described structure includes a cooling component 5 comprising an air duct 51, which is specifically positioned above the mounting plate 2. The air duct 51 has an air inlet 511 and an air outlet 512 facing the screen 3. The air inlet 511 of the air duct 51 can be connected to an external cold air source, so that the cold air provided by the cold air source can be delivered to the screen 3 through the air outlet 512, thereby cooling the screen 3 and the thermosetting adhesive. Of course, the number of air outlets 512 of the air duct 51 can be more than one, as long as it can deliver the cold air provided by the cold air source to the screen 3.

[0055] In other alternative implementations, such as Figure 2 As shown, the cooling assembly 5 includes at least one air blowing block 52, which is mounted on or near the mounting plate 2. The air blowing block 52 has an air chamber 521 inside, and the air inlet end 522 of the air chamber 521 is connected to an external cold air source. The side wall of the air blowing block 52 facing the hollow area 31 is provided with an air blowing port 523 that communicates with the air chamber 521. The cold air provided by the cold air source is blown onto the screen 3 through the air blowing port 523.

[0056] By configuring the cooling assembly 5 to include an air blowing block 52, which is specifically mounted on the mounting plate 2, the air blowing block 52 has an air chamber 521 inside, and the air inlet 522 of the air chamber 521 is connected to an external cold air source. At the same time, the side wall of the air blowing block 52 facing the hollow area 31 is provided with an air blowing port 523 connected to the air chamber 521, so that the cold air provided by the cold air source can be blown onto the screen 3 through the air chamber 521 and the air blowing port 523, thereby cooling the screen 3 and the thermosetting adhesive. Of course, the air blowing block 52 can also be located near the mounting plate 2, and the number of air blowing blocks 52 can be more than one, as long as the air inlet 522 of all air blowing blocks 52 is connected to the external cold air source and the air blowing port 523 faces the hollow area 31 on the mounting plate 2.

[0057] Optional, such as Figures 2 to 5As shown, the cooling assembly 5 includes an air duct 51 and at least one air blowing block 52, wherein: the air duct 51 is disposed above the mounting plate 2, the air duct 51 has an air inlet 511 and at least one air outlet 512, and the air inlet 511 of the air duct 51 is connected to an external cold air source; the air blowing block 52 is mounted on or near the mounting plate 2, and the air blowing block 52 has an air chamber 521 inside, and the air inlet 522 of the air chamber 521 is connected to one of the air outlets 512 of the air duct 51 through a connecting pipe; the side wall of the air blowing block 52 facing the hollow area 31 is provided with an air blowing port 523 that communicates with the air chamber 521, and the air blowing port 523 is used to blow cold air onto the mesh plate 3.

[0058] By configuring the cooling assembly 5 to include an air duct 51 and an air blowing block 52 (though there may be more than one air blowing block 52), the air duct 51 is positioned above the mounting plate 2 and above the air blowing block 52. The air duct 51 has an air inlet 511 and an air outlet 512 (again, there may be more than one air outlet 512). The air inlet 511 of the air duct 51 is specifically connected to an external cold air source, allowing the cold air supplied by the cold air source to flow into the air duct 51 through the air inlet 511. The air blowing block 52 is specifically mounted on the mounting plate 2; alternatively, the air blowing block 52 may be positioned near the mounting plate 2. The air blower 52 is positioned such that an air chamber 521 is provided inside the air blower block 52. The air inlet 522 of the air chamber 521 can be connected to the air outlet 512 of the air duct 51 through a connecting pipe, so that the cold air in the air duct 51 can flow into the air chamber 521 through the air outlet 512 of the air duct 51 and the air inlet 522 of the air blower block 52. In addition, an air blower 523 is provided on the side wall of the air blower block 52 facing the hollow area 31 on the mounting plate 2, which is connected to the air chamber 521. In this way, the cold air in the air chamber 521 can be blown onto the screen 3 through the air blower 523, and the screen 3 and the thermosetting adhesive on the screen 3 are cooled.

[0059] Optional, such as Figure 2 As shown, there are two air blowing blocks 52, which are arranged opposite each other on both sides of the hollow area 31.

[0060] By setting two air blowing blocks 52, both air blowing blocks 52 can be set on or near the mounting plate 2, and the two air blowing blocks 52 are specifically set opposite to each other on both sides of the hollow area 31 on the mounting plate 2. In this way, the two air blowing blocks 52 can blow the cold air provided by the cold air source onto the screen 3, thereby cooling the screen 3 and the thermosetting adhesive. At the same time, since there are two air blowing blocks 52, and the two air blowing blocks 52 are set opposite to each other, the two air blowing blocks 52 can cool the screen 3 from two directions at the same time, which helps to improve the uniformity of cooling.

[0061] In other alternative embodiments, four air-blowing blocks 52 are provided, and the four air-blowing blocks 52 are arranged in pairs facing each other on the periphery of the hollow area 31.

[0062] By setting four air blowing blocks 52, each of which can be positioned on or near the mounting plate 2, and specifically arranged in pairs opposite each other on the periphery of the cutout area 31 on the mounting plate 2, the four air blowing blocks 52 can blow the cold air provided by the cold air source onto the screen 3, thereby cooling the screen 3 and the thermosetting adhesive. At the same time, since there are four air blowing blocks 52, and the four air blowing blocks 52 are arranged in pairs opposite each other, the four air blowing blocks 52 can simultaneously cool the screen 3 from four directions, which helps to further improve the uniformity of cooling.

[0063] Of course, in other alternative embodiments, the number of air-blowing blocks 52 may be three, five or more.

[0064] Optional, such as Figures 3 to 5 As shown, the air outlet 523 is set at a downward angle, and the cold air is blown obliquely downward through the air outlet 523 onto the screen 3.

[0065] The screen printing device 10 with the above structure, by setting the air blowing port 523 to be inclined downward, allows cold air to be blown obliquely downward through the air blowing port 523 onto the screen 3, thereby cooling the screen 3 and the thermosetting adhesive on the screen 3. Since the air blowing port 523 is set to be inclined downward, the cold air can maintain a stable blowing direction under the action of gravity after being blown out through the air blowing port 523, thereby allowing more cold air to be blown onto the screen 3, which is beneficial to improving the cooling efficiency of the cold air.

[0066] Optionally, the number of air outlets 512 of the air duct 51 is the same as the number of air blowing blocks 52, and the air outlets 512 are connected to the air inlet ends 522 of the air blowing blocks 52 in a one-to-one correspondence.

[0067] By setting the number of air outlets 512 of the air duct 51 to be equal to the number of air blowing blocks 52, the cooling assembly 5 blows cold air only through the air blowing blocks 52 near the screen 3, thereby cooling the area near the screen 3 and preventing the thermosetting adhesive from deteriorating.

[0068] In other alternative embodiments, the number of air outlets 512 in the air duct 51 is greater than the number of air blowing blocks 52. The air inlet 522 of each air blowing block 52 is connected to one air outlet 512, and the remaining air outlets 512 are positioned facing the screen 3 and higher than the air blowing blocks 52, for directly supplying cold air to the screen 3 from above. For example... Figure 2As shown, the air duct 51 has three air outlets 512 and two air blowing blocks 52. The air outlets 512 on both sides are connected to the air inlet 522 of one air blowing block 52, and the air outlet 512 in the middle blows cold air directly toward the mesh plate 3.

[0069] By setting the number of air outlets 512 of the air duct 51 to be greater than the number of air blowing blocks 52, the cooling component 5 can not only blow cold air near the screen 3 through the air blowing blocks 52, but also blow cold air above the screen 3 through the air duct 51, thereby cooling more areas above the screen 3 and improving the cooling effect on the screen 3.

[0070] Optional, such as Figure 1 As shown, the screen printing device 10 also includes a cover 4, which is fixedly disposed relative to the mounting plate 2. The bottom of the cover 4 is open, and the cover 4 covers the top of the mounting plate 2. The cover 4 is used to restrict the cold air blown out by the cooling assembly 5 from escaping.

[0071] By providing a cover 4 on the screen printing device 10, specifically fixed relative to the mounting plate 2, with the bottom of the cover 4 being open, the cover 4 can be placed over the mounting plate 2, thereby forming a relatively sealed space between the cover 4 and the mounting plate 2. Thus, when cold air supplied by an external cold air source blows towards the screen 3, the cover 4 can confine the cold air within the space formed by the cover 4 and the mounting plate 2, thereby preventing the cold air from dissipating.

[0072] Optionally, the air duct 51 is fixedly installed on the top of the cover 4 and located on the outside of the cover 4, and all the air outlets 512 of the air duct 51 penetrate the cover 4 and extend into the cover 4. Thus, when the number of air outlets 512 of the air duct 51 is greater than the number of air blowing blocks 52, the extra air outlets 512 on the air duct 51 can cool the space on the upper side of the cover 4, and the air blowing blocks 52 can cool the space on the lower side of the cover 4, thereby cooling the entire space inside the cover 4 and ensuring the uniformity of cooling.

[0073] Optional, such as Figure 2 As shown, the screen printing device 10 also includes a lifting drive assembly 6, which includes a lifting drive part 61 and a lifting part 62. The lifting drive part 61 is mounted on the support frame 1; the lifting part 62 is slidably connected to the support frame 1 and connected to the drive end of the lifting drive part 61; the mounting plate 2 is fixedly connected to the lifting part 62.

[0074] By setting up a lifting drive assembly 6, which specifically includes a lifting drive part 61 and a lifting part 62, and a mounting plate 2 fixedly connected to the lifting part 62, the lifting part 62 can drive the mounting plate 2 to move up and down under the drive of the lifting drive part 61, thereby adjusting the position of the screen 3 so that the screen 3 is closer to or further away from the battery cell to be printed.

[0075] The lifting drive unit 61 can be any type of linear actuator, such as a linear motor or cylinder.

[0076] Optional, such as Figure 2 As shown, the screen printing device 10 also includes a squeegee assembly 7 and a translation drive unit 8. The squeegee assembly 7 is disposed above the screen 3 and is connected to the drive end of the translation drive unit 8. The translation drive unit 8 is used to drive the squeegee assembly 7 to move within the cutout area 31 to scrape the thermosetting adhesive on the screen 3.

[0077] By providing a squeegee assembly 7 and a translation drive unit 8 on the screen printing device 10, the squeegee assembly 7 can be moved in the cutout area 31 above the screen 3 by the translation drive unit 8 to scrape the thermosetting adhesive on the screen 3, thereby achieving the printing of adhesive onto the battery cell.

[0078] The translation drive unit 8 can be any type of linear actuator, such as a linear motor or cylinder.

[0079] Optionally, the scraper assembly 7 includes a first scraper and a second scraper, which are configured to alternately rise and fall to abut against the screen 3. After the first scraper or the second scraper abuts against the screen 3, the translation drive unit 8 drives the first scraper and the second scraper to translate, so that the scraper abutting against the screen 3 prints the thermosetting adhesive on the screen 3 onto the battery cell below the screen 3.

[0080] This application also provides a battery cell printing apparatus, such as... Figures 1 to 6 As shown, the battery cell printing equipment includes the screen printing device 10 and the support platform 9. The support platform 9 is located below the mounting plate 2 of the screen printing device 10. The support platform 9 is used to support the battery cells, and the screen printing device 10 is used to print thermosetting adhesive dots onto the battery cells on the support platform 9.

[0081] By setting up the screen printing device 10 and the carrier platform 9 as described above, wherein the carrier platform 9 is located below the mounting plate 2 of the screen printing device 10 and the carrier platform 9 is capable of supporting the battery cell, the screen printing device 10 can print thermosetting adhesive dots onto the battery cell on the carrier platform 9 when the battery cell is supported on the carrier platform 9. Since the screen printing device 10 is the screen printing device described above, the heat emitted by the battery cell will be neutralized by the cold air in the screen printing device 10, so as not to affect the characteristics of the thermosetting adhesive on the screen 3, and thus not to affect the printing quality of the battery cell.

[0082] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
