[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0039] Please refer to Figures 1-4 , Figure 1 This is a schematic diagram of the structure of the full-screen photovoltaic module frame glue applicator 100 from a first-view perspective provided in this embodiment; Figure 2 for Figure 1 A magnified view of a section at point A in the middle; Figure 3 This is a cross-sectional schematic diagram of the glue applicator 100 for the frame of the full-screen photovoltaic module provided in this embodiment; Figure 4 This is a schematic diagram of the structure of the full-screen photovoltaic module frame glue applicator 100 and the full-screen photovoltaic frame 200 from a second perspective, provided in this embodiment.

[0040] This utility model provides a glue applicator for the frame of a full-screen photovoltaic module, including a glue gun and a glue applicator head 100. The glue applicator head 100 includes a fixing part 110, which can be connected to the glue gun so that the glue applicator head 100 can be mounted on the glue gun. The fixing part 110 is provided with a connecting channel 111 and a glue inlet 112 that are interconnected. The glue inlet 112 and the connecting channel 111 are connected to the flow channel of the glue gun, so that the glue in the flow channel can enter the connecting channel 111 through the glue inlet 112.

[0041] It should be noted that in this embodiment, the end of the glue gun is a cylindrical structure. Therefore, the glue applicator 100 of the full-screen photovoltaic module frame in this embodiment is a cylindrical structure so that the fixing part 110 can be sleeved on the end of the glue gun, and the cross-section of the connecting channel 111 is circular.

[0042] The full-screen photovoltaic module frame glue applicator 100 in this embodiment also includes a glue dispensing part 120. One end of the glue dispensing part 120 is connected to the fixing part 110, and the glue dispensing part 120 is provided with a glue dispensing channel 123 connected by a connecting channel 111, so that glue can flow into the glue dispensing channel 123 through the connecting channel 111.

[0043] It should be noted that, according to Figure 4 It is known that the bezel of a full-screen display has two surfaces that need to be glued: the B-side and the C-side. However, the existing glue applicator only applies glue to the inner wall of the C-side of the bezel, which makes it very easy for the B-side to run out of glue, affecting the yield rate.

[0044] Based on this, in this embodiment, the other end of the glue dispensing section 120 is provided with a first cross-section 121 and a second cross-section 122, and the first cross-section 121 and the second cross-section 122 are respectively provided with a first glue outlet 1211 and a second glue outlet 1221 communicating with the glue dispensing channel 123, so that the glue located in the glue dispensing channel 123 can flow out through the first glue outlet 1211 and the second glue outlet 1221.

[0045] The first section 121 is directly opposite to Figure 4 The second section 122 of the B-side of the full-screen photovoltaic bezel 200 shown is directly opposite to... Figure 4 The C-side of the full-screen photovoltaic frame 200 shown is designed so that the glue flowing from the first glue outlet 1211 can be applied to the B-side of the full-screen photovoltaic frame 200, while the glue flowing from the second glue outlet 1221 can be applied to the C-side of the full-screen photovoltaic frame 200. This ensures that both the B-side and C-side of the full-screen photovoltaic frame 200 are filled with glue, preventing glue shortages and improving product quality.

[0046] Based on the above, the B-side and C-side of the full-screen photovoltaic frame 200 are set at an angle to support the photovoltaic module. Specifically, the B-side abuts against the side wall of the photovoltaic module, while the C-side abuts against the back of the photovoltaic module. Therefore, in order to ensure more thorough glue application and avoid glue waste, the shape and size of the first glue outlet 1211 and the second glue outlet 1221 need to be adjusted according to the shape and length of the B-side and C-side.

[0047] Understandably, the photovoltaic module in this embodiment has a square structure, so its contact surface with the full-screen photovoltaic frame 200 is rectangular. Therefore, the first adhesive outlet 1211 and the second adhesive outlet 1221 are also rectangular. Furthermore, the height of the sidewall of the photovoltaic module in this embodiment is less than the length of the back side. In addition, to ensure more thorough adhesive application, the length d1 of the first adhesive outlet 1211 should correspond to the height of the sidewall, and the length d2 of the second adhesive outlet 1221 should correspond to the length of the back side. Therefore, d1 < d2.

[0048] Since the B-side and C-side of the full-screen photovoltaic frame 200 abut against the sidewall and back of the photovoltaic module respectively, and the photovoltaic module has a square structure, the B-side and C-side are perpendicular to each other. In order to ensure more thorough glue application and avoid insufficient glue, in this embodiment, the first section 121 and the second section 122 are also perpendicular to each other, that is, the included angle between the first section 121 and the second section 122 is 90°.

[0049] Further, please refer to Figures 1-4 In this embodiment, the full-screen photovoltaic module frame glue applicator 100 also includes a partition 130. One end of the partition 130 is connected to the first section 121 and the second section 122, and the other end of the partition 130 extends toward the fixing part 110 to divide the glue dispensing channel 123 into the first segment 1231 and the second segment 1232.

[0050] Understandably, as a large amount of adhesive flows into the dispensing channel 123, the partition 130 separates the adhesive, allowing a portion of the adhesive to flow into the first segment 1231 and another portion into the second segment 1232. In this embodiment, the first segment 1231 is connected to the first dispensing port 1211, and the second segment 1232 is connected to the second dispensing port 1221. Therefore, the adhesive in the first segment 1231 flows out through the first dispensing port 1211 to be applied to the B side of the photovoltaic module, while the adhesive in the second segment 1232 flows out through the second dispensing port 1221 to be applied to the C side of the photovoltaic module.

[0051] Furthermore, since the length d1 of the first glue outlet 1211 is less than the length d2 of the second glue outlet 1221, and the widths of the first glue outlet 1211 and the second glue outlet 1221 are equal, the area of ​​the first glue outlet 1211 is less than the area of ​​the second glue outlet 1221. To ensure sufficient glue flows out from both the first glue outlet 1211 and the second glue outlet 1221, the volume of the first segment 1231 should be less than the volume of the second segment 1232.

[0052] It should be noted that in this embodiment, the end of the partition 130 near the fixing part 110 is tapered, that is, the end of the partition 130 is a pointed tip, which can increase the pressure between the partition 130 and the glue, separate the glue, and the pointed tip has a guiding function, so that the glue flows smoothly into the first segment 1231 and the second segment 1232 and does not stay at the end of the partition 130.

[0053] Furthermore, this embodiment also includes a flow-promoting section 140 and a flow-stabilizing section 150. One end of the flow-promoting section 140 is connected to the dispensing section 120, and the other end is connected to one end of the flow-stabilizing section 150. The other end of the flow-stabilizing section 150 is connected to the fixing section 110. It can be understood that the flow-promoting section 140 and the flow-stabilizing section 150 are both located between the fixing section 110 and the dispensing section 120, and the fixing section 110, the flow-stabilizing section 150, the flow-promoting section, and the dispensing section 120 are connected sequentially from top to bottom.

[0054] The flow-promoting section 140 is provided with a flow-promoting channel 141, and the flow-stabilizing section 150 is provided with a flow-stabilizing channel 151. As described above, the flow-promoting channel 141 and the flow-stabilizing channel 151 are connected, and both are connected to the connecting channel 111 and the glue outlet channel 123 (first segment 1231 and second segment 1232). During the glue application process, the glue flows sequentially through the connecting channel 111, the flow-stabilizing channel 151, the flow-promoting channel 141, and the glue outlet channel 123, before exiting through the first glue outlet 1211 and the second glue outlet 1221.

[0055] The flow stabilizing channel 151 and the connecting channel 111 are both circular in cross-section, and the diameter of the cross-section of the flow stabilizing channel 151 is smaller than the diameter of the cross-section of the connecting channel 111. That is, the area of ​​the cross-section of the flow stabilizing channel 151 is smaller than the area of ​​the cross-section of the connecting channel 111, thereby reducing the flow rate of the adhesive, allowing the adhesive to flow evenly, ensuring the stability of the adhesive flow, and enabling the adhesive to flow at a uniform speed.

[0056] However, since the glue outlet channel 123 in the embodiment is divided into a first segment 1231 and a second segment 1232 under the action of the partition 130, in order to ensure that there is enough glue in the first segment 1231 and the second segment 1232 and to avoid insufficient glue in the full-screen photovoltaic frame 200, this embodiment sets a flow channel 141 with a gradually increasing cross-sectional area along its axial direction to gradually increase the flow rate of the glue and ensure that there is enough glue to enter the first segment 1231 and the second segment 1232.

[0057] It should be noted that the maximum cross-sectional area of ​​the flow channel 141 is smaller than that of the connecting channel 111, meaning that the flow rate of the adhesive in the flow channel 141 is less than that in the connecting channel 111.

[0058] Understandably, since both the first glue outlet 1211 and the second glue outlet 1221 are rectangular, in order to accommodate the first glue outlet 1211 and the second glue outlet 1221, the cross-sections of the first segment 1231 and the second segment 1232 in this embodiment are also rectangular. The length and width of the cross-section of the first segment 1231 are equal to those of the first glue outlet 1211. Similarly, the length and width of the second segment 1232 are equal to those of the second glue outlet 1221.

[0059] Based on the above, the full-screen photovoltaic module frame glue applicator 100 in this embodiment is made of rigid plastic, that is, it is a rigid plastic glue applicator, which is low in cost and has high structural strength. It can be manufactured by injection molding, and the manufacturing process is simple and convenient.

[0060] In summary, the full-screen photovoltaic module frame glue applicator 100 in this embodiment is connected to the glue gun via a fixing part 110, allowing it to be mounted on the glue gun. The glue gun's flow channel, glue inlet 112, connecting channel 111, glue outlet channel 123, first glue outlet 1211, and second glue outlet 1221 are interconnected, enabling the glue in the glue gun to be smoothly applied to the full-screen photovoltaic frame 200, thus achieving glue application. Furthermore, this embodiment, by providing a first cross-section 121 and a second cross-section 122, allows the glue to flow out through the first glue outlet 1211 on the first cross-section 121 and the second glue outlet 1221 on the second cross-section 122, thereby applying glue to both surfaces of the full-screen photovoltaic frame 200. This ensures more thorough glue application, avoids insufficient glue, and improves product quality.

[0061] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
