Description

Technical Field

[0002] The gluing process for the bottom of a photovoltaic junction box is a crucial step in the manufacturing of photovoltaic modules. Its primary purpose is to enhance the sealing and mechanical connection stability between the junction box and the module backplane, while also providing additional waterproofing and insulation protection. During this process, the design and performance of the glue nozzle (also known as a glue injection nozzle or glue head) are crucial for ensuring accurate and even distribution of the glue and gluing efficiency. In the prior art, the glue applied to the bottom of a photovoltaic junction box is typically applied in a rectangular shape connected end to end. This is also typically done manually, making it difficult to control the uniformity of the glue application and prone to glue overflow or hollowing. Furthermore, the glue application length varies for photovoltaic junction boxes of different sizes, making it increasingly difficult to achieve accurate and stable glue application as the length increases.

[0034] Reference Figure 1~Figure 2 An embodiment of the present utility model proposes a glue nozzle, including a support member 1, the support member 1 having a glue injection cavity 101, and the support member 1 is cylindrical, a guide platform 2 is set on the support member 1, and a glue injection member 3 is rotatably set on the guide platform 2, and the rotation axis coincides with the axis of the support member 1. The glue injection member 3 has a glue injection channel 301, and the glue injection channel 301 is connected to the glue injection cavity 101.

[0035] In this embodiment, considering that the uniformity of glue application in the related art is difficult to be well controlled and that glue overflow or hollowing is prone to occur, a support member 1 and a guide platform 2 are provided in this solution. The support member 1 is designed as a cylindrical structure, and a glue injection cavity 101 is formed inside, which serves as the main channel for the circulation of glue. The cylindrical design of the support member 1 ensures that the glue nozzle fits well with the bottom position of the photovoltaic junction box. At the same time, the stability of the cylindrical structure helps to improve the positioning accuracy during the glue application process. The guide platform 2 is arranged on the support member 1 and serves as the rotation fulcrum of the glue injection member 3. The design of the guide platform 2 needs to take into account the coordination with the glue injection member 3 to ensure that the glue injection member 3 can remain stable during the rotation process. At the same time, the guide platform 2 also assumes the function of guiding the glue injection member 3 to move along a preset trajectory to adapt to the glue application requirements of photovoltaic junction boxes of different sizes. The glue injection member 3 is the core component of the glue application nozzle. A glue injection channel 301 is provided inside it, which is connected to the glue injection cavity 101 of the support member 1 to form a complete conveying path for the glue from the glue barrel to the bottom of the junction box. The glue injection part 3 is rotatably arranged on the guide platform 2, and its rotation axis coincides with the axis of the support part 1, ensuring uniform distribution of glue during rotation and avoiding glue overflow or hollowing phenomena common in traditional gluing.

[0036] Furthermore, the glue injection part 3 includes a support seat 4 rotatably set on the guide platform 2, the support seat 4 has a guide slope 401, the glue injection head 5 has a first sliding part 501, the first sliding part 501 is slidably set on the guide slope 401, and the glue injection channel 301 is located in the glue injection head 5.

[0037] In this embodiment, different gluing ranges are required when gluing the bottom of photovoltaic junction boxes of different sizes. A support seat 4 is provided in this solution, and a guide slope 401 is provided on the support seat 4. The distance between the glue injection head 5 and the support member 1 gradually becomes farther during the process of sliding downward on the guide slope 401. As the support seat 4 rotates, glue strips of different lengths can be injected, and the glue injection channel 301 is connected to the glue injection cavity 101. During the transmission process, they are connected by a hose with a certain length margin, which can achieve a good glue liquid transfer function after the glue injection head 5 slides on the guide slope 401.

[0038] Furthermore, the support seat 4 is a frustum-shaped, with several horizontally arranged annular guide grooves 402 arranged in sequence from top to bottom, and the injection head 5 has a second sliding part 502, which is slidably arranged in the annular guide groove 402, and the second sliding part 502 moves between several annular guide grooves 402.

[0039] In this embodiment, considering that the moving trajectory of the glue injection head 5 needs to be highly stable and the moving speed needs to be uniform and steady, a number of horizontally arranged annular guide grooves 402 are opened on the support seat 4 in this solution, and a second sliding part 502 is provided on the glue injection head 5, that is, the position of the first sliding part 501 sliding on the guide slope 401 is determined by the position of the first sliding part 501 and the second sliding part 502 after cooperation with the annular guide groove 402, and the spacing between the annular guide grooves 402 is set to enable the glue nozzle to inject a conventional standard photovoltaic junction box glue strip size, when the second sliding part 502 is adjusted into the annular guide groove 402 of the corresponding circumference, a stable fixed-length glue operation can be achieved by sliding one circle, and the glue trajectory is neat, which is convenient for the subsequent gluing operation.

[0040] Furthermore, the rotating frame 6 is rotatably arranged on the support member 1 , and one end of the flexible tube 7 passes through the rotating frame 6 and is connected to the glue injection cavity 101 , and the other end is connected to the glue injection channel 301 .

[0041] In this embodiment, a rotating frame 6 is rotatably provided on the support member 1. The rotating frame 6 is the power source for the support seat 4 to rotate on the guide platform 2. A flexible pipe fitting 7 is connected between the rotating frame 6 and the injection channel 301. The flexible pipe fitting 7 has a certain length margin and can be extended and retracted within a certain range. That is, when the injection head 5 slides on the support seat 4 and when the support seat 4 slides on the guide platform 2, the flexible pipe fitting 7 can adaptively adjust its own length to prevent malfunctions during the operation of the device.

[0042] Furthermore, it also includes a rotating guide member 8 rotatably set on the support member 1, the rotating axes of the rotating guide member 8, the rotating frame 6 and the injection member 3 are collinear, the support seat 4 is slidably set on the rotating guide member 8, and the sliding direction is radially along the rotation trajectory of the rotating guide member 8.

[0043] In this embodiment, considering that when gluing the bottom of the photovoltaic junction box, the most ideal gluing trajectory is a rounded rectangle, because the guide platform 2 is set to a rounded rectangle in this solution, the shape of the annular guide groove 402 is also the same, and the moving trajectory of the support seat 4 is therefore not circular. Taking this into consideration, a rotating guide member 8 is provided in this solution. While the rotating guide member 8 drives the support seat 4 to rotate, the support seat 4 can also achieve a certain range of radial sliding on the rotating guide member 8, so that the support seat 4 will not be affected by the shape of the guide platform 2 and the trajectory of the annular guide groove 402 while being driven by stable rotation, and will not be stuck or fall off.

[0044] Furthermore, the rotating guide member 8 has a slide groove 801, the support seat 4 has a third sliding part 403, the third sliding part 403 is slidably set in the slide groove 801, and also includes an elastic member 9 with one end set on the inner wall of the slide groove 801 and the other end slidably set on the third sliding part 403, providing force for the third sliding part 403 to approach the support member 1.

[0045] In this embodiment, a slide groove 801 is provided on the rotating guide member 8, and the direction of the slide groove 801 is along the radial direction of rotation of the rotating guide member 8. The third sliding part 403 on the support seat 4 slides in the slide groove 801. This design can make the rotation trajectory of the support seat 4 more stable and controllable, so that the final gluing has a good finished product effect. In addition, an elastic part 9 is also provided in the slide groove 801. The elastic part 9 can always provide a force for the support seat 4 toward the support member 1. This design can make the first sliding part 501 and the second sliding part 502 stably abut against the inner wall of the annular guide groove 402, thereby achieving a stable movement state and preventing falling off.

[0046] Furthermore, it also includes a support leg 10, which is arranged at the bottom of the support member 1 and is arranged on the support member 1 to be lifted and slidable.

[0047] In this embodiment, the support leg 10 is provided at the bottom of the support member 1, and a certain telescopic relationship exists between the support leg 10 and the support member 1. The support leg 10 can be actively and adaptively adjusted in height according to the height of the glue injection head 5 and the spatial position required for processing, so that the glue injection head 5 maintains an optimal distance from the surface to be glued. This makes the device have a wider range of applications and good practicality.

[0048] Furthermore, the glue injection parts 3 are arranged in pairs, and the glue injection parts 3 arranged in pairs are all slidably arranged on the guide platform 2.

[0049] In this embodiment, since the guide platform 2 is set to a rounded rectangle, it can better solve the technical problems to be solved in this solution, and the glue injection parts 3 are set in pairs to achieve more efficient gluing work. The glue injection parts 3 can be set to one pair or two pairs, all set in pairs, and rotate uniformly under the drive of the rotating frame 6, so that the trajectory and movement state of each rotating frame 6 are the same, and good synchronous drive can be achieved.

[0050] Furthermore, the guide platform 2 has a plurality of inclined portions 201 , which are arranged circumferentially, and two adjacent inclined portions 201 are smoothly transitioned to each other.

[0051] In this embodiment, the inclined portion 201 can make the position conversion of the first sliding portion 501 between different annular guide grooves 402 smoother and smoother, and the smooth transition connection between two adjacent inclined portions 201 also contributes to the stability of the conversion process, further improving the working efficiency of the device during gluing.

[0052] Furthermore, the support seat 4 has a roller portion 404 , which is in rolling contact with the inner wall of the annular guide groove 402 .

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
