Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module production, specifically relating to a structure for a photovoltaic module adhesive nozzle. Background Technology

[0002] In the production process of photovoltaic modules, the adhesive application process is crucial, as it directly affects the sealing performance of the photovoltaic modules. By applying adhesive to the joints between the frame and components such as glass and backsheet of the photovoltaic modules, it is possible to effectively prevent external moisture, dust, impurities, etc. from entering the module. At the same time, it firmly fixes the frame to the main body of the module, making the entire structure of the photovoltaic module more stable.

[0003] However, the silicone inside the glass groove is not squeezed evenly during the process of the glass and the frame being squeezed together. This results in uneven silicone at the corner position. Only areas with less silicone or no overflow are filled with silicone. The amount of silicone in the filled area and the overflow area is inconsistent, which is not aesthetically pleasing. The original overflowed silicone is not regulated and appears as an arc shape. It does not cover the gap between the frame and the glass well, which increases the risk to reliability. Utility Model Content

[0004] The purpose of this utility model is to provide a glue nozzle structure for photovoltaic modules, in order to solve the problems mentioned in the background art, such as uneven extrusion of silicone inside the glass groove during the mutual compression of glass and frame, resulting in uneven silicone at the corner position, only applying glue to areas with less glue or no overflow, inconsistent glue amount between the applied area and the overflow area, unsatisfactory appearance, and the original overflowed silicone not being properly shaped into an arc, failing to adequately cover the gap between the frame and glass, thus increasing reliability risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module glue applicator structure, comprising a glue applicator body;

[0006] An installation area is provided at the top of the nozzle body, and a thread is provided inside the installation area. The installation area is connected and fixed to the external thread on the glue gun through the thread, and a sealing ring is provided inside the installation area.

[0007] An initial mixing area is provided below the installation area, a first process mixing area is provided below the initial mixing area, and a silicone mixing area is provided at the bottom of the first process mixing area.

[0008] A beveled area is provided at the bottom of the silicone mixing area, the angle of the beveled area is 5-50°, and a first sealant leak, a second sealant leak, or a third sealant leak is provided at the front side of the beveled area.

[0009] A silicone molding brush plane is provided at the rear side of the silicone mixing area, and a silicone mixing area connection port is provided at the top of the silicone mixing area. The silicone mixing area is connected to the nozzle body through the silicone mixing area connection port.

[0010] The first sealant leak is an equilateral triangle structure, the second sealant leak is an arc structure, and the third sealant leak is a trapezoidal structure.

[0011] The maximum width of the outlet is less than the width of the long side of the silicone mixing area, and the maximum height of the outlet can be adjusted to 6-8mm depending on the amount and speed of dispensing.

[0012] A second process mixing area may also be provided below the initial mixing area. The interior of the first process mixing area is a smooth structure, and the interior of the second process mixing area is provided with a threaded rotating structure. A double-pipe connection port is provided at the top of the second process mixing area. Two hose connection ports are provided at the top of the double-pipe connection port, and a double-pipe connection port connection part is provided at the bottom of the double-pipe connection port. The double-pipe connection port connection part is threadedly connected to the installation area.

[0013] The length of the second process mixing zone is adjusted according to the mixing requirements of the adhesive and the viscosity of the silicone. The internal thread structure of the second process mixing zone gradually decreases in size from the inlet. The nozzle body switches between dual-tube modes through a dual-tube connection port.

[0014] A nozzle connection port may be provided at the bottom of the nozzle body, and a nozzle enlargement port may be provided at the bottom of the nozzle connection port.

[0015] Compared with the prior art, this utility model provides a photovoltaic module adhesive nozzle structure, which has the following beneficial effects:

[0016] 1. By setting up a silicone mixing area, a beveled area, a first sealant outlet, a second sealant outlet, a third sealant outlet, a silicone molding surface, and a connection point for the silicone mixing area, the specific angle of the beveled area alters the direction and speed distribution of the adhesive flow. Compared to a traditional flat bottom, the beveled design generates a certain lateral force when the adhesive flows out, which helps the adhesive spread better on the photovoltaic module surface and improves the uniformity of the application. Especially when dealing with large-area application needs, it can effectively reduce the phenomenon of adhesive accumulation or gaps. Different shaped sealant outlets meet diverse application requirements. The equilateral triangular structure of the first sealant outlet results in more concentrated adhesive flow and is suitable for areas requiring precise application. The arc-shaped structure of the second sealant outlet provides relatively soft and uniform adhesive flow and can be used in areas where a more uniform adhesive layer thickness is required. The trapezoidal structure of the third sealant outlet has unique advantages in adhesive volume and coverage, enabling rapid filling. The larger gaps or areas allow operators to flexibly choose the appropriate nozzle shape according to the actual photovoltaic module gluing scenario, improving gluing efficiency and quality. The silicone molding and brushing surface can smooth the surface of the glue after extrusion, which helps to form a smooth and regular glue layer surface. This not only improves the appearance quality of the photovoltaic module, but also makes the glue layer thickness more uniform, enhancing the sealing effect and structural stability, and avoiding problems such as poor sealing caused by uneven glue layer surface. The silicone mixing area is connected to the nozzle body through the silicone mixing area connector, ensuring structural stability and smooth glue flow. The stable connection structure can withstand the pressure generated by the glue during the flow process, preventing loosening or leakage; the smooth connection ensures that the glue can flow from the nozzle body into the silicone mixing area for final mixing and dispensing without obstruction, ensuring the continuity and stability of the gluing process to achieve the best gluing effect.

[0017] 2. The system features an initial mixing zone, a second-stage mixing zone, a first-stage mixing zone, a spiral rotating structure, a dual-tube connection port, a hose connection port, and a connection part for the dual-tube connection port. The spiral rotating structure within the second-stage mixing zone provides strong stirring during adhesive flow. The adhesive rotates along the spiral structure, significantly increasing the contact and mixing opportunities between different adhesive components, resulting in more thorough and uniform mixing. This effectively improves the mixing quality and meets the requirements of applications with high adhesive mixing standards. The two hose connections at the top of the dual-tube connection port can be connected to different adhesives, enabling a dual-tube mode. The bottom connection part of the dual-tube connection port is threaded into the installation area, ensuring a secure connection and easy disassembly. Operators can easily replace different specifications of the dual-tube connection port or perform cleaning and maintenance as needed, improving the versatility and ease of use of the nozzle. The length of the second-stage mixing zone can be adjusted according to the mixing requirements of the adhesive and the viscosity of the silicone, providing strong... The nozzle offers flexibility. For adhesives with high mixing requirements and high silicone viscosity, the length of this area can be appropriately increased to allow for more time and space for mixing. For adhesives that are relatively easy to mix, the length can be shortened to improve dispensing efficiency and meet the diverse mixing needs of different types of adhesives. The internal thread structure gradually decreases in size from the inlet. At the inlet, the larger thread structure allows the adhesive to enter quickly and be initially dispersed. As the adhesive flows towards the outlet, the thread gradually decreases, enhancing the squeezing and stirring effect on the adhesive, further refining the mixing effect, and ensuring that the adhesive is efficiently and uniformly mixed throughout the entire second-stage mixing area. This design allows the nozzle to operate in both single-tube and double-tube modes. When facing different photovoltaic module dispensing needs, operators can easily and quickly switch to double-tube mode by changing the double-tube connector to achieve proportional mixing of two types of adhesives, expanding the nozzle's functionality and improving its applicability and efficiency in different working scenarios.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-6 The diagram shows a photovoltaic module adhesive applicator structure, including an applicator body;

[0027] An installation area is provided at the top of the nozzle body, and a thread is provided inside the installation area. The installation area is connected and fixed to the external thread on the glue gun through the thread, and a sealing ring is provided inside the installation area.

[0028] An initial mixing area is provided below the installation area, a first process mixing area is provided below the initial mixing area, and a silicone mixing area is provided at the bottom of the first process mixing area.

[0029] A beveled area is provided at the bottom of the silicone mixing area, the angle of the beveled area is 5-50°, and a first sealant leak, a second sealant leak, or a third sealant leak is provided at the front side of the beveled area.

[0030] A silicone molding brush plane is provided at the rear side of the silicone mixing area, and a silicone mixing area connection port is provided at the top of the silicone mixing area. The silicone mixing area is connected to the nozzle body through the silicone mixing area connection port.

[0031] The first sealant leak is an equilateral triangle structure, the second sealant leak is an arc structure, and the third sealant leak is a trapezoidal structure.

[0032] The maximum width of the outlet is less than the width of the long side of the silicone mixing area, and the maximum height of the outlet can be adjusted to 6-8mm depending on the amount and speed of dispensing.

[0033] A second process mixing area may also be provided below the initial mixing area. The interior of the first process mixing area is a smooth structure, and the interior of the second process mixing area is provided with a threaded rotating structure. A double-pipe connection port is provided at the top of the second process mixing area. Two hose connection ports are provided at the top of the double-pipe connection port, and a double-pipe connection port connection part is provided at the bottom of the double-pipe connection port. The double-pipe connection port connection part is threadedly connected to the installation area.

[0034] The length of the second process mixing zone is adjusted according to the mixing requirements of the adhesive and the viscosity of the silicone. The internal thread structure of the second process mixing zone gradually decreases in size from the inlet. The nozzle body switches between dual-tube modes through a dual-tube connection port.

[0035] A nozzle connection port may be provided at the bottom of the nozzle body, and a nozzle enlargement port may be provided at the bottom of the nozzle connection port.

[0036] In this embodiment, the specific implementation steps of a photovoltaic module adhesive nozzle structure are as follows: The internal thread of the mounting area 2 above the nozzle body 1 is screwed onto the corresponding external thread on the glue gun. During installation, ensure the sealing ring 6 is in the correct position to provide a good seal and prevent glue leakage at the connection point. This completes the installation and fixing of the nozzle and glue gun. Two or more types of glue to be mixed are connected to the two glue tube connection ports 8 at the top of the dual-tube connection port 7 through glue tubes. If a dual-tube mode is used, after the glue enters the dual-tube connection port 7, it enters the mounting area 2 through the dual-tube connection port connection part 19, and then flows into the initial mixing area 3. 3. The adhesive begins initial mixing, preparing for more thorough mixing later. In single-tube mode without using the second mixing zone 9, the adhesive, after initial mixing in the initial mixing zone 3, directly enters the first mixing zone 4. Because the first mixing zone 4 has a smooth internal structure, the adhesive continues to flow and undergo a certain degree of mixing within it, before flowing to the silicone mixing zone 5. In dual-tube mode using the second mixing zone 9, the adhesive flows out of the initial mixing zone 3 and enters the second mixing zone 9. The spiral rotating structure 18 inside the second mixing zone 9 continuously stirs and rotates the adhesive during its flow. To further promote the mixing of the adhesive, the length of the second-stage mixing zone 9 can be adjusted according to the mixing requirements of the adhesive and the viscosity of the silicone. Its internal thread structure gradually decreases in size from the inlet to optimize the mixing effect. The mixed adhesive then enters the silicone mixing zone 5, where it undergoes final thorough mixing. Depending on actual needs, a suitable sealant outlet is selected on the front side of the beveled area 10 at the bottom of the silicone mixing zone 5, such as the first sealant outlet 14 with an equilateral triangle structure, the second sealant outlet 15 with an arc shape, or the third sealant outlet 16 with a trapezoidal shape for dispensing the adhesive. The maximum width of the outlet... The nozzle width is smaller than the long side width of the silicone mixing area 5. The maximum height of the nozzle can be adjusted to 6-8mm according to the dispensing volume and speed to ensure uniform and appropriate dispensing. During the dispensing process, the silicone molding brushing plane 17 on the back side of the silicone mixing area 5 can shape the extruded glue to a certain extent, making the silicone shape after dispensing more regular. If necessary, other auxiliary components can be connected through the nozzle connection port 11 at the bottom of the nozzle body 1. The nozzle enlargement port 12 at the bottom of the nozzle connection port 11 helps to adjust the dispensing range. After connecting the relevant components, start the glue gun and apply the mixed glue evenly to the parts of the photovoltaic module that need to be glued to complete the glue dispensing operation.

[0037] like Figure 3 and Figure 6As shown, a beveled area is provided at the bottom of the silicone mixing area, with an angle of 5-50°. A first, second, or third sealant outlet is provided at the front of the beveled area. A silicone molding brush plane is provided at the rear of the silicone mixing area. A silicone mixing area connection port is provided at the top of the silicone mixing area. The silicone mixing area is connected to the nozzle body through the silicone mixing area connection port. The first sealant outlet has an equilateral triangle structure, the second sealant outlet has an arc structure, and the third sealant outlet has a trapezoidal structure. The maximum width of the outlet is less than the width of the long side of the silicone mixing area. The maximum height of the outlet can be adjusted to 6-8mm according to the dispensing volume and dispensing speed.

[0038] Preferably, the specific angle setting of the beveled area 10 changes the direction and speed distribution of the adhesive flow. Compared with the traditional flat bottom, the beveled design allows the adhesive to generate a certain lateral force when flowing out, which helps the adhesive to spread better on the surface of the photovoltaic module and improves the uniformity of the application. Especially when dealing with the application needs of large areas, it can effectively reduce the phenomenon of adhesive accumulation or gaps. Different shapes of sealant outlets meet diverse application needs. The first sealant outlet 14 with an equilateral triangle structure has a more concentrated adhesive flow and is suitable for areas that require precise application. The second sealant outlet 15 with an arc structure has a relatively soft and uniform adhesive flow and can be used in areas where the adhesive layer thickness requires more uniformity. The third sealant outlet 16 with a trapezoidal structure has unique advantages in adhesive volume and coverage area, and can quickly fill larger gaps or areas, allowing operators to apply sealant according to the actual photovoltaic module. The flexible selection of appropriate nozzle shapes improves glue application efficiency and quality. The silicone molding and brushing surface 17 smooths the glue surface after extrusion, resulting in a smooth and regular glue layer. This not only enhances the appearance of the photovoltaic module but also makes the glue layer thickness more uniform, improving sealing performance and structural stability. It avoids problems such as poor sealing caused by uneven glue surface. The silicone mixing area 5 is connected to the nozzle body 1 via the silicone mixing area connector 13, ensuring structural stability and smooth glue flow. The stable connection structure can withstand the pressure generated during glue flow, preventing loosening or leakage. The smooth connection ensures that the glue can flow unimpeded from the nozzle body 1 into the silicone mixing area 5 for final mixing and dispensing, guaranteeing the continuity and stability of the glue application process for optimal results.

[0039] like Figure 1-2 and Figure 5As shown, a second process mixing area can also be provided below the initial mixing area. The interior of the first process mixing area is a smooth structure, and the interior of the second process mixing area is provided with a threaded rotating structure. A double-pipe connection port is provided at the top of the second process mixing area, and two glue tube connection ports are provided at the top of the double-pipe connection port. A double-pipe connection port connection part is provided at the bottom of the double-pipe connection port. The double-pipe connection port connection part is threadedly connected to the installation area. The length of the second process mixing area is adjusted according to the mixing requirements of the glue and the viscosity of the silicone. The threaded structure inside the second process mixing area gradually decreases in size from the inlet. The glue nozzle body switches between double-pipe modes through the double-pipe connection port.

[0040] Preferably, the spiral rotating structure 18 inside the second-process mixing zone 9 provides a strong stirring effect during the glue flow. The glue rotates and advances along the spiral structure, greatly increasing the contact and mixing opportunities between different glue components, making the glue mixture more thorough and uniform, effectively improving the glue mixing quality, and meeting the application scenarios with high glue mixing requirements. The two glue tube connection ports 8 at the top of the dual-tube connection port 7 can be connected to different glues respectively to realize the dual-tube mode. The dual-tube connection port connection part 19 at the bottom is threadedly connected to the installation area 2, ensuring a stable connection and convenient disassembly and assembly. Operators can easily replace the dual-tube connection port 7 of different specifications or perform cleaning and maintenance as needed, improving the versatility and ease of use of the nozzle. The length of the second-process mixing zone 9 can be adjusted according to the glue mixing requirements and silicone viscosity, providing high flexibility. For glues with high mixing requirements and high silicone viscosity, it can... By appropriately increasing the length of this area, more time and space are allowed for the adhesive to mix. For adhesives that are relatively easy to mix, the length is shortened to improve dispensing efficiency and meet the diverse mixing needs of different types of adhesives. The internal thread structure gradually decreases in size from the inlet. At the inlet, the larger thread structure allows the adhesive to enter quickly and be initially dispersed. As the adhesive flows towards the outlet, the thread gradually decreases, enhancing the squeezing and stirring effect on the adhesive, further refining the mixing effect, and ensuring that the adhesive is efficiently and uniformly mixed throughout the entire second-process mixing area 9. This design allows the nozzle to operate in both single-tube and double-tube modes. When facing different photovoltaic module dispensing needs, operators can easily and quickly switch to double-tube mode by changing the double-tube connector 7 to achieve proportional mixing of two types of adhesives, expanding the nozzle's functionality and improving its applicability and efficiency in different working scenarios.

[0041] like Figure 4 As shown, a nozzle connection port may be provided at the bottom of the nozzle body, and a nozzle enlargement port may be provided at the bottom of the nozzle connection port.

[0042] Optionally, the nozzle connector 11 provides a standardized connection method for the nozzle body 1, enabling it to be easily connected to other auxiliary tools or components. It can connect to different types of extension tubes, coating tools, etc., allowing for expansion and adjustment of the nozzle according to specific work scenarios and needs. This increases the nozzle's flexibility and applicability. In actual use, the nozzle may need to be replaced due to wear, blockage, or different dispensing tasks. The nozzle connector 11 simplifies the nozzle replacement process, allowing for easy and quick removal of the old nozzle and installation of the new one without complicated operations. This effectively improves work efficiency and reduces downtime caused by nozzle replacement. Especially for some high-viscosity adhesives, this design ensures smooth flow, guaranteeing the continuity and stability of dispensing work and reducing work interruptions and nozzle damage caused by blockages.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
