[0047] In the photovoltaic industry, aluminum profiles are used to construct the frame of the photovoltaic cells, which protects the photovoltaic cells, fixes and seals the solar panels, enhances the overall strength of the module, and extends the service life of the photovoltaic module. This process requires the use of aluminum profiles with an L-shaped cross section. The ends of adjacent profiles are cut at an angle and then butt-welded to form a quadrilateral frame. Therefore, the welding quality of the aluminum profiles determines the overall strength and even the service life of the photovoltaic module.

[0048] Currently, the manual welding of aluminum profile frames requires the creation of tooling structures to position the aluminum profiles before welding. However, existing welding tooling structures are too simple, with few positioning components, making it impossible to position all profiles simultaneously. This results in poor positioning, severely affecting the welding quality of the aluminum profile frames and even the overall product quality of the photovoltaic modules.

[0049] The welding fixture provided in this embodiment can simultaneously position three or four profiles to be welded by setting two first positioning parts and one second positioning part on the base plate. This ensures the complete positioning of the triangular or quadrilateral frame and avoids the problem of poor welding quality caused by inaccurate alignment of the profiles to be welded during the welding process, which affects the strength of the frame and even the overall quality of the photovoltaic module.

[0050] Example 1

[0051] Reference Appendix Figure 1This embodiment discloses a welding fixture, which includes a base plate 1, two first positioning parts 2 and a second positioning part 3; the two first positioning parts 2 are spaced apart on the base plate 1 along a first direction a, and the first positioning part 2 includes a first positioning member 21 and a second positioning member 22 at a specified included angle, the first positioning member 21 and the second positioning member 22 are respectively used to abut and fit against the ends of adjacent profiles 4 to be welded; the second positioning part 22 is located on the base plate 1 along a second direction b of the two first positioning parts 2, and the second positioning part 22 is used to move and abut against the ends or sides of the profiles 4 to be welded;

[0052] The second positioning part 3 and the two first positioning parts 2 form a positioning area to surround the profile 4 to be welded within the positioning area, and the first direction a and the second direction b satisfy the perpendicular condition.

[0053] Specifically, to address the problem that existing manual welding fixtures for aluminum profiles are too simple, have too few positioning parts, and result in poor positioning, which seriously affects the welding quality of the aluminum profile frame and even the overall product quality of the photovoltaic module, this embodiment provides a welding fixture. Two first positioning parts 2 and one second positioning part 3 are set on the base plate 1 to achieve synchronous positioning of three or four profiles 4 to be welded. The first positioning element 21 and the second positioning element 22 of the first positioning part 2 can cooperate to position the ends of two adjacent profiles 4 to be welded. The second positioning part 3 can position the ends of two adjacent profiles 4 to be welded or the side of a profile, thereby ensuring that the triangular or quadrilateral frame formed by the profiles 4 to be welded can be fully positioned and welded, ensuring stable positioning and improving welding quality.

[0054] In this embodiment, the first direction a and the second direction b can be the width direction and the length direction of the base plate 1, respectively; the first direction a and the second direction b satisfying the perpendicularity condition can be mutually perpendicular or approximately perpendicular. In this embodiment, the first direction a and the second direction b can also be any two parallel directions on the base plate 1 that satisfy the perpendicularity condition, without further limitations.

[0055] In this embodiment, the welding fixture is designed for manual welding operations; the profile 4 to be welded is an L-shaped or C-shaped profile structure, i.e. Figure 3 As shown.

[0056] Among them, the base plate 1 is a rigid flat plate structure, which can be made of materials such as stainless steel, plastic steel, and glass. It can provide a stable and flat support surface for the positioning part and the profile 4 to be welded, ensuring stable positioning and accurate welding.

[0057] The first positioning part 2 is a rigid structure, which includes a first positioning element 21 and a second positioning element 22. The first positioning element 21 and the second positioning element 22 can be, but are not limited to, plate-shaped, block-shaped, strip-shaped, or other structural forms. The specified included angle between the first positioning element 21 and the second positioning element 22 can be designed and adjusted between 45 and 90 degrees according to the actual welding requirements. For example, if the profile 4 to be welded needs to form a triangular frame, the specified included angle between the first positioning element 21 and the second positioning element 22 can be set to 60 degrees; if the profile 4 to be welded needs to form a rectangular frame, the specified included angle between the first positioning element 21 and the second positioning element 22 can be set to 90 degrees; if the profile 4 to be welded needs to form other quadrilateral frames, such as parallelograms, trapezoids, etc., the angle between the first positioning element 21 and the second positioning element 22 can be adjusted accordingly. The surface of the first positioning member 21 facing the second positioning member 22 is used to adhere to the outer wall of one profile 4 to be welded. Correspondingly, the surface of the second positioning member 22 facing the first positioning member 21 is used to adhere to the outer wall of another profile 4 to be welded. The ends of the two profiles 4 to be welded abut against each other within the included angle formed by the first positioning member 21 and the second positioning member 22, and this point is the welding point. It is easy to understand that the included angle area formed by the two positioning members of the two first positioning parts 2 is opposite, and thus the two first positioning parts 2 can simultaneously position the ends of three profiles 4 to be welded. In this embodiment, the first positioning part 2 can be fixed to the base plate 1 by means of welding, screwing, bonding, etc.

[0058] The second positioning part 3 is a rigid structure, which is disposed on the second direction b of the two first positioning parts 2. It can be on the center line of the two first positioning parts 2 parallel to the second direction b, or on the straight line containing any point between the two first positioning parts 2 parallel to the second direction b; for example: Figure 1 and Figure 2As shown, when the second positioning part 3 is on the center line of the two first positioning parts 2, the profile 4 to be welded can be formed into an isosceles triangle or an equilateral triangle frame or a rectangular frame; when the second positioning part 3 corresponds to one first positioning part 2, the profile 4 to be welded can be formed into a right triangle or a rectangular frame. The second positioning part 3 can have the same structure as the first positioning part 2 or be arc-shaped. In this configuration, the second positioning part 3 can simultaneously position the ends of two adjacent profiles 4 to be welded. In this configuration, the positioning area can only form a triangular region. Alternatively, the second positioning part 3 can be linear, limiting the profile 4 extending along the first direction a to prevent displacement along the second direction b. In this configuration, the included angle between the two positioning members of the first positioning part 2 can be set to 90 degrees. The two first positioning parts 2 can then limit the three profiles 4 forming a U-shape. When used in conjunction with the second positioning part 3, the rectangular frame can be positioned and welded. In this configuration, the two positioning members of the first positioning part 2 can maintain an acute angle. The second positioning part 3 can also simultaneously abut the ends of two adjacent profiles 4 to be welded. Therefore, in this configuration, the positioning area can also form a quadrilateral region, a triangular region, or a trapezoidal region. Of course, the number of second positioning parts 3 in this embodiment can be designed and adjusted according to actual needs. In this embodiment, the second positioning part 3 can be fixed to the base plate 1 by means of welding, screwing, bonding, etc.

[0059] As listed above, by setting two first positioning parts 2 and one second positioning part 3 on the base plate, the synchronous positioning of three or four profiles to be welded can be achieved simultaneously, ensuring the complete positioning of the triangular or quadrilateral frame and avoiding the problem of poor welding quality caused by inaccurate alignment of profiles during the welding process, which affects the strength of the frame and even the overall product quality of the photovoltaic module.

[0060] In this article, the term "and / or" is merely a description of the relationship between related objects, identifying three possible relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included simultaneously, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0061] In some embodiments, the welding fixture provided in this embodiment, in order to achieve the positioning function of the second positioning part 3, can be configured in at least the following two forms:

[0062] The first method, see attached document. Figure 2 The second positioning part 3 includes a positioning surface 31 extending along the first direction a. The positioning surface 31 is perpendicular to the base plate 1. The positioning surface 31 is used to flexibly abut against and fit the end or side of the profile 4 to be welded away from the first positioning part 2.

[0063] Understandably, in this configuration, the dimensions of the second positioning part 3 along the first direction a are not limited and can be designed and adjusted according to actual needs. The specific shape of the second positioning part 3 can also be designed and adjusted according to actual needs, such as a quadrangular prism, a cylinder, etc., as long as it has a positioning surface 31 perpendicular to the base plate 1. The positioning surface 31 can fit against an inner surface of the profile 4 to be welded, so that the profile 4 to be welded cannot be displaced along the second direction b. In this configuration, refer to the attached... Figure 2 The included angle between the two positioning members of the first positioning part 2 can be set to 90 degrees. Then, the two first positioning parts 2 can limit the three profiles 4 to be welded that form a U-shape. When combined with the second positioning part 3, the rectangular frame can be positioned and welded. In this configuration, the two positioning members of the first positioning part 2 can maintain an acute angle, and the second positioning part 3 can also simultaneously abut the ends of two adjacent profiles 4 to be welded.

[0064] The second method is detailed in the appendix. Figure 1 The second positioning part 3 includes a third positioning member 32 and a fourth positioning member 33; the third positioning member 32 and the fourth positioning member 33 form a specified angle, and the direction of the angle is opposite to the second direction b. The third positioning member 32 and the fourth positioning member 33 are respectively used to abut and fit the ends of the adjacent profiles 4 to be welded.

[0065] Understandably, in this configuration, the second positioning part 3 and the first positioning part 2 have the same structure. The structure and configuration of the third positioning member 32 and the fourth positioning member 33 are based on the description of the first positioning member 21 and the second positioning member 22 mentioned above, and will not be elaborated further here. It is not difficult to understand that the included angle formed by the third positioning member 32 and the fourth positioning member 33 is opposite to the second direction b, that is, towards the side where the first positioning part 2 is located. In this configuration, if the second positioning part 3 corresponds to any first positioning part, then the included angle between the third positioning member 32 and the fourth positioning member 33 can be 90 degrees or an acute angle. If the second positioning part 3 corresponds to the center line of the two first positioning parts 2, then the included angle between the third positioning member 32 and the fourth positioning member 33 can be an acute angle.

[0066] Further, see attached document. Figure 3 The welding fixture provided in this embodiment includes two second positioning parts 3 in a specific implementation. The two second positioning parts 3 are arranged one-to-one with the two first positioning parts 2 in the second direction b. The two first positioning parts 2 and the two second positioning parts 3 form a quadrilateral positioning area.

[0067] It is understood that conventional photovoltaic modules are rectangular. Therefore, in this embodiment, to accommodate the welding of rectangular frames, two second positioning parts 3 are provided. The two second positioning parts 3 are arranged one-to-one with the two first positioning parts 2, forming a quadrilateral positioning area. Of course, the two second positioning parts 3 can directly correspond to the two first positioning parts 2 in the second direction b to form a rectangular positioning area, or the two positioning parts 3 can obliquely correspond to the two first positioning parts 2 in the second direction b to form a parallelogram positioning area. In this arrangement, the second positioning parts 3 can be set to have the same structure as the first positioning parts 2, or they can be set to be straight lines with positioning surfaces 31. For example, when the second positioning parts 3 have the same structure as the first positioning parts 2, the included angle between the two positioning parts in the first positioning parts 2 and the second positioning parts 3 can be 90 degrees or an acute angle, thus corresponding to the rectangular positioning area and the parallelogram positioning area. When the second positioning parts 3 are straight lines, the two second positioning parts 3 can cooperate to position the three profiles 4 to be welded in a U-shape.

[0068] Further, see attached document. Figure 3 The welding fixture provided in this embodiment, in a specific implementation, also includes a first support member 5 and a second support member 6; the first support member 5 extends along a first direction a between two first positioning parts 2, the first support member 5 includes a first support surface 51 and a second support surface 52, the first support surface 51 is perpendicular to the bottom plate 1, the second support surface 52 extends at a second specified angle with the first support surface 51 at one end of the first support surface 51 away from the bottom plate 1 and extends in the direction of the second positioning part 3, the first support surface 51 and the second support surface 52 are used to respectively fit two adjacent inner surfaces on the profile 4 to be welded;

[0069] The second support member 6 is disposed between the first positioning part 2 and the second positioning part 3, and the second support member 6 has the same structure as the first support member 5.

[0070] Understandably, in order to improve the positioning effect of the profile 4 to be welded, this embodiment provides a first support member 5 and a second support member 6. Both the first support member 5 and the second support member 6 are rigid structures, which can be prisms or hollow prisms, as long as they have a first support surface 51 and a second support surface 52. The first support member 5 supports and positions the profile 4 to be welded between the two first positioning parts 2, and the second support member 5 is provided between the first positioning part 2 and the second positioning part 3 to support and position the profile 4 to be welded. For example: Figure 2 As shown, the two second support members 6 are set at an angle, such as... Figure 3As shown, the two second support members 6 are arranged perpendicularly to the first support member 5 along the second direction b. In this embodiment, the first support surface 51 and the second support surface 52 can be flat or irregularly shaped, as long as they can fit and conform to the inner surface of the profile 4 to be welded. The first support surface 51 is arranged perpendicular to the bottom plate, and the second included angle between the second support surface 52 and the first support surface 51 can be designed and adjusted according to the structural form of the profile 4 to be welded, for example: Figure 3 As shown, if the cross-section of the profile 4 to be welded is a standard L-shape, then the second included angle is 90 degrees; if the cross-section of the profile 4 to be welded is a bend with an acute or obtuse angle, then the second included angle can be designed accordingly, which will not be elaborated here. Of course, if the cross-section of the profile 4 to be welded is U-shaped, then, provided that the second supporting surface 52 is perpendicular to the first supporting surface 51, a third supporting surface (not shown in the figure) parallel to the first supporting surface 51 can also be provided at the end of the second supporting surface 52 that is away from the first supporting surface 51.

[0071] In some embodiments, refer to the appendix Figure 4 The welding fixture provided in this embodiment further includes at least one third positioning part 7 in a specific implementation; the third positioning part 7 includes a positioning head 71, which is movably connected to the second support surface 52 of the first support member 5 or the second support member 6; wherein, the third positioning part 7 is movably disposed on the base plate 1 along the first direction a or the second direction b, so that the positioning head 71 can reciprocate along the first direction a or the second direction b to movably abut against the profile 4 to be welded.

[0072] It is understandable that, in order to improve the positioning effect of the profile 4 to be welded, a third positioning part 7 is provided in this embodiment. The third positioning part 7 acts on the edge of the profile 4 to be welded facing the positioning area within the positioning area. That is, the positioning head 71 of the third positioning part 7 can cooperate with the first positioning part 2 or the second positioning part 3 to clamp the profile 4 to be welded to ensure its stability. The positioning head 71 can be plate-shaped, block-shaped, disc-shaped, etc., as long as it can stably support the profile 4 to be welded. Specifically, the positioning head 71 is movably connected to the second support surface 52, so that the positioning head 71 can support the edge of the profile 4 to be welded that is attached to the second support surface 52. In this embodiment, the third positioning part 7 can be set alone along the first direction a, alone along the second direction b, or simultaneously in the first direction a and the second direction b. The mobility of the third positioning part 7 along the first direction a or the second direction b can be achieved by setting a slider or pulley on the third positioning part 7 and cooperating with setting a groove or rail on the base plate 1. This setting is easily understood by those skilled in the art and will not be described in detail here.

[0073] In some embodiments, refer to the appendix Figure 4 and attached Figure 5In this embodiment, the welding fixture provided includes a third positioning part 7 comprising a clamping plate 72 and a locking rod 73. The clamping plate 72 has a through hole 74 along a first direction a or a second direction b, and positioning heads 71 ​​are formed at both ends of the clamping plate 71 along the first direction a or the second direction b. The base plate 1 has a locking hole 11 that is adapted to the locking rod 73. When the locking rod 73 passes through the through hole 74 and is inserted into the locking hole 11, the positioning head 71 can reciprocate along the first direction a or the second direction b with the through hole 74.

[0074] It is understood that, in order to make the positioning head 71 movable and easily adjustable, this embodiment sets the third positioning part 7 in the form of a clamping plate 72 and a locking rod 73. The clamping plate 72 is a rigid plate, and its two ends can serve as the positioning head 71, abutting the edge of the profile 4 to be welded through its sidewalls extending along its thickness direction. The locking rod 73 can be, but is not limited to, a screw. Adaptively, the locking hole 11 on the base plate 1 is a threaded hole. The locking rod 73, when screwed into the locking hole 11, can generate a guiding function and a sliding function. The through hole 74 on the clamping plate 72 can correspondingly form a slide or groove. The clamping plate 72 can move the position of the positioning head 71 through the movement of the through hole 74 relative to the locking rod 73. At the same time, the locking rod 73 can also adjust the degree of fixation of the clamping plate 72 by adjusting the degree of screwing with the locking hole 11. The above settings are easily understood by those skilled in the art and will not be elaborated further here. Of course, the number of the third positioning parts 7 can be designed and adjusted according to actual needs. For example, refer to the attached figure. Figure 4 Two third positioning parts 7 can be sequentially arranged along the second direction b; a third support 8 is provided between the two second support members 6 corresponding to the two first positioning parts 2, and the third support 8 is at the same height as the second support member 6, so that the adjacent positioning heads 71 ​​on the two third positioning parts 7 can simultaneously overlap the third support 8; the third support 8 can be integrally formed with the second support member 6 or can be formed by subsequent docking. Of course, the third support 8 does not necessarily have to be connected to the second support member 6, as long as it can provide an overlapping platform for the positioning heads 71 ​​on the adjacent clamping plate 72. Similarly, two third positioning parts 7 can also be sequentially arranged in the first direction a, and the arrangement method is the same as above, which will not be described in detail here.

[0075] In some embodiments, refer to the appendix Figure 5 In this embodiment, the welding fixture provided includes a third positioning part 7 that further includes a locking base 75. The locking base 75 is fixed to the base plate 1, and a locking hole 11 is provided on the side of the locking base 75 away from the base 1.

[0076] Understandably, in order for the positioning head 71 to be able to rest on the second support surface 52, this embodiment provides a locking base 75. The locking base 75 can provide height compensation in the direction perpendicular to the base plate 1, ensuring that the height of the positioning head 71 can be adapted to the second support surface 52.
