Abstract
Description
Technical Field
[0001] This application relates to the field of spraying technology, and more particularly to a partition device and spraying equipment. Background Technology
[0002] In the manufacturing process of photovoltaic modules, spraying is a crucial step. Certain chemical solutions are sprayed onto the surface of the photovoltaic module as catalysts, and after a chemical reaction, their performance and efficiency can be improved.
[0003] The chemical solution spraying process involves the product being conveyed to the workstation via a conveyor device. Then, the nozzles repeatedly spray a mist of chemical solution according to a pre-set program. Simultaneously, a top-mounted FFU (Fan Filter Unit) blows air downwards, while a bottom-mounted exhaust fan removes excess sprayed chemical solution. However, this process results in some chemical solution adhering to the back of the photovoltaic module, causing the sun-facing side to be contaminated and affecting subsequent processes. Existing solutions include lowering the nozzle height or increasing the bottom exhaust fan force; however, these measures are insufficient to completely prevent this issue. Therefore, a new solution is urgently needed to address the technical problem of chemical solution contamination on the back of photovoltaic modules. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a separation device and a spraying equipment to solve the technical problem of chemical solution contamination on the back of photovoltaic modules.

[0007] The centerline of the first air cavity coincides with the centerline of the air outlet plate;
[0008] The second air cavity is disposed at least along the circumference of the first air cavity on both sides of the first air cavity and is in communication with the first air cavity;
[0009] The first surface of the air outlet plate is provided with a first air outlet hole that communicates with the first air cavity at a position corresponding to the first air cavity.
[0010] The first surface of the air outlet plate is provided with a second air outlet hole that communicates with the second air cavity at a position corresponding to the second air cavity;

[0021] Furthermore, the spacer structure is provided with a connecting hole for connecting the first air cavity and the second air cavity.
[0022] Furthermore, a communication gap is formed between the spacer structure and the cover plate or the cavity to connect the first air cavity and the second air cavity.
[0023] Furthermore, there are two second air cavities, which are symmetrically arranged relative to the first air cavity.
[0024] Furthermore, the spacing structure includes two first straight spacing strips;
[0025] Two first straight spacer bars are arranged parallel to each other and spaced apart on both sides of the center line of the cavity, dividing the cavity into three first chambers;
[0026] The first cavity located in the middle forms the first air cavity;

[0047] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable 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 of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0048] This application discloses a partition device.
[0049] Please see Figure 1 as well as Figure 2 One embodiment of the partition device provided in this application includes:
[0050] Air outlet plate 1 and air supply device 2 (air supply device 2 can be a blower, no specific restrictions).
[0051] The air outlet plate 1 is provided with a first air cavity 111 and a second air cavity 112. The purpose of aligning the center line of the first air cavity 111 with the center line of the air outlet plate 1 is to place the first air cavity 111 at the center of the air outlet plate 1.
[0052] The second air cavity 112 is located at least along the circumference of the first air cavity 111 on both sides of the first air cavity 111 and is connected to the first air cavity 111. The purpose of this design is to enable the gas delivered to the back of the workpiece 4 to be coated to diffuse from the middle to both sides. Of course, it is preferred to design it to diffuse from the middle to the surrounding area.
[0053] On the first surface of the air outlet plate 1, a first air outlet hole 121 is arranged in an array corresponding to the position of the first air cavity 111, and a second air outlet hole 122 is arranged in an array corresponding to the position of the second air cavity 112, which is connected to the second air cavity 112.
[0054] The diameter of the first air outlet 121 is smaller than that of the second air outlet 122. The air outlet plate 1 is provided with an air inlet channel 113 connecting to the first air chamber 111. The air supply device 2 is connected to the air inlet channel 113 via an air supply pipe 3 to supply air to the air outlet plate 1. Since the air inlet channel 113 is directly connected to the first air chamber 111, the gas input by the air supply device 2 first enters the first air chamber 111. Simultaneously, because the diameter of the first air outlet 121 is smaller, the airflow from the first air outlet 121 is stronger, thus creating a strong wind. Conversely, the gas in the second air chamber 112 enters later than the gas in the first air chamber 111, and the diameter of the second air outlet 122 is larger, therefore the output airflow is weaker, thus creating a weak wind.
[0055] The isolation device designed in this application can be positioned below the spraying station to supply air to the back of the workpiece 4 (such as glass) to be sprayed at the spraying station. The air supply device 2 first sends the gas into the first air chamber 111, and then into the second air chamber 112. Since the gas enters the first air chamber 111 first and the first air outlet 121 connected to the first air chamber 111 has a smaller aperture, the gas delivered to the back of the workpiece 4 to be sprayed diffuses in a manner with strong wind in the middle and weak wind around the periphery, blowing away the atomized chemical solution, thereby completely preventing the atomized chemical solution from being adsorbed onto the back of the workpiece 4 to be sprayed, achieving the purpose of back isolation from contamination, and ensuring that the overall spraying effect is achieved as expected.
[0056] The above is Embodiment 1 of a partition device provided in this application. The following is Embodiment 2 of a partition device provided in this application. Please refer to the following for details. Figures 1 to 4 .
[0057] Based on the solution of Embodiment 1 above:
[0058] Furthermore, such as Figure 2 As shown, the air outlet plate 1 includes an air outlet base 11 and a cover plate 12;
[0059] A recessed cavity is provided on one side of the air outlet base 11, and a cover plate 12 is detachably installed on one side of the air outlet base 11 to seal the recessed cavity. The detachable cover plate 12 makes the partition structure inside the recessed cavity easily accessible. When it is necessary to replace the partition structure inside the recessed cavity or clean the inside of the recessed cavity, the operator can easily remove the cover plate 12 and operate directly inside without the need for complicated disassembly of the entire device, which greatly shortens the maintenance time and reduces the maintenance difficulty. As for the detachable connection method, it can be bolt connection, snap connection, etc., without restriction.
[0060] The inner side of the cover plate 12 or the cavity is provided with a partition structure. The partition is designed to be detachable, so that different partition structures can be replaced as needed to divide the cavity into the required chamber distribution. The detachable connection method can be bolt connection, etc., without limitation.
[0061] The partition structure is used to divide the concave cavity into a first air cavity 111 and a second air cavity 112.
[0062] The first air outlet 121 and the second air outlet 122 are provided on the cover plate 12.
[0063] The air inlet channel 113 is located on the air outlet base 11, specifically on the back of the air outlet base 11.
[0064] Furthermore, regarding the design of the connection between the first air cavity 111 and the second air cavity 112, a connecting hole (not shown in the figure) can be provided on the partition structure to connect the first air cavity 111 and the second air cavity 112.
[0065] Of course, a connecting gap can also be formed between the partition structure and the cover plate 12 or the cavity to connect the first air cavity 111 and the second air cavity 112. Those skilled in the art can make appropriate design changes based on this, without any specific limitations.
[0066] Furthermore, such as Figure 3 As shown, taking the second air chamber 112 as an example, it can be symmetrically arranged relative to the first air chamber 111 to achieve diffusion with medium to strong winds and weak winds on the left and right sides, that is, diffusion from the center to the sides.
[0067] Furthermore, taking the second air chamber 112 as an example, such as... Figure 3 As shown, the spacer structure design includes two first straight spacer bars 114; the two first straight spacer bars 114 are arranged parallel to each other and spaced apart on both sides of the center line of the cavity, and divide the cavity into three first chambers.
[0068] The first cavity located in the middle forms the first air cavity 111, and the first cavities located on both sides form the second air cavity 112.
[0069] Furthermore, such as Figure 3 As shown, the spacing structure also includes two second straight spacers 115.
[0070] Two second straight spacers 115 are perpendicular to the first straight spacer 114 and located between the two first straight spacers 114; the two second straight spacers 115 are parallel and spaced apart on the other two sides of the center line of the cavity, for dividing the first cavity located in the middle into three second cavities.
[0071] Dividing the first air chamber 111 into upper, middle, and lower chambers allows for a distribution of medium-strong winds and weak winds at the top and bottom within the first air chamber 111. Combined with weak winds on both sides, this results in a distribution of medium-strong winds and weak winds around the perimeter. Compared to a distribution of medium-strong winds with weak winds on both sides, this achieves a better diffusion effect.
[0072] Furthermore, in order to achieve a better diffusion effect, such as Figure 4 As shown, the second air cavity 112 is a single, annular cavity that surrounds the first air cavity 111.
[0073] Furthermore, such as Figure 4 As shown, in the design of the annular cavity, the spacer structure can be an annular spacer bar 116, whose center line coincides with the center line of the concave cavity, and is used to divide the concave cavity into two third cavities.
[0074] The third cavity located within the annular spacer 116 forms the first air cavity 111, and the third cavity located outside the annular spacer 116 forms the second air cavity 112.
[0075] like Figure 5 As shown, this application also discloses a spraying device, including a partition device.
[0076] The air outlet plate 1 of the partition device is located below the spraying station, and its first air outlet 121 and second air outlet 122 are vertically upward. The air supply device 2 of the partition device can be located outside the conveyor 5, while the air outlet plate 1 is located inside the conveyor 5, below the conveyor roller 51 of the conveyor 5, and directed towards the spraying station. When the workpiece 4 to be sprayed moves to the spraying station and stops, the spraying device located above begins to spray, and at the same time, the FFU (not shown in the figure) located above circulates air, while the exhaust fan located below begins to exhaust air (not shown in the figure). The partition device designed in this application operates synchronously to form a partition effect on the back of the workpiece 4 to be sprayed, so that the back of the workpiece 4 to be sprayed will not be contaminated.
[0077] The above provides a detailed description of the partition device and spraying equipment provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
