Description

Technical Field

[0001] This application belongs to the field of photovoltaic module technology, specifically relating to a photovoltaic module clamp. Background Technology

[0002] During the production of full-screen photovoltaic (PV) modules, the inverted placement of the modules on the production line can lead to insufficient bonding between the glass on the upper surface of the PV module and the laminated components due to incomplete adhesive curing, resulting in separation during transport. Furthermore, insufficient adhesive curing can also cause adhesive overflow between the laminated components and the frame of the PV module, resulting in a weak connection. These problems directly affect the effective connection of the PV module, thereby reducing its overall reliability. Utility Model Content

[0003] One objective of this invention is to provide a photovoltaic module clamp that effectively solves the problem of insufficient connection between glass and laminate caused by incomplete curing of colloid in photovoltaic modules during the production line.

[0004] According to an embodiment of this application, a first aspect provides a photovoltaic module clamp, the photovoltaic module clamp comprising:

[0005] Support portion, the support portion extending along a first direction;

[0006] A first limiting part is disposed at one end of the support part. The first limiting part applies a force to the glass surface of the photovoltaic module to keep the glass in contact with the laminate of the photovoltaic module.

[0007] The second limiting part extends along a second direction and is disposed at the other end of the support part relative to the first limiting part, and is located on the same side of the support part as the first limiting part. The second limiting part is used to support the frame of the photovoltaic module and to fix and constrain the frame.

[0008] In one embodiment, the first limiting portion further forms a limiting space for accommodating the colloid overflowing from between the frame and the laminate.

[0009] In one embodiment, the first limiting portion includes a pressing portion and a connecting portion, the connecting portion connecting the pressing portion and the supporting portion, the pressing portion being used to apply pressure to the glass surface so that the glass adheres to the laminate.

[0010] In one embodiment, the connecting portion has an arc-shaped structure and extends obliquely towards the glass surface, and the inner side of the arc-shaped structure forms the limiting space for accommodating the colloid overflowing from between the frame and the laminate.

[0011] In one embodiment, a fixing part is provided at the end of the second limiting part away from the supporting part, and a groove formed between the fixing part and the second limiting part is used to engage the extension of the frame.

[0012] In one embodiment, the photovoltaic module clamp is made of an elastic material.

[0013] In one embodiment, the vertical distance between the fixing part and the pressing part is less than the height of the frame, so that the first limiting part and the second limiting part can apply elastic pressure to the frame.

[0014] In one embodiment, the first limiting portion extends along a third direction, and the extension length of the first limiting portion is the same as the length of the photovoltaic module, and the second limiting portion is spaced apart along the third direction.

[0015] In one embodiment, the length of the pressing part in the third direction is the same as that of the first limiting part, and the width of the pressing part is less than or equal to 10 centimeters.

[0016] In one embodiment, the support portion is provided with a through hole, which is used to separate the photovoltaic module clamp from the photovoltaic module by external force.

[0017] The photovoltaic module clamp of this application applies force to the glass surface through a first limiting part, ensuring a tight fit between the glass and the laminate. Simultaneously, a second limiting part supports and fixes the frame of the photovoltaic module, thereby securing the opposite ends of the photovoltaic module. This photovoltaic module clamp effectively maintains a tight fit between the glass and the laminate of the photovoltaic module, significantly reducing the problem of insufficient connection caused by incomplete curing of the adhesive in the production line.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] As mentioned in the background, during the production of full-screen photovoltaic (PV) modules, the inverted placement of the PV modules on the production line can lead to insufficient bonding between the glass on the upper surface of the PV module and the laminated components due to incomplete adhesive curing, resulting in separation during transport. Furthermore, insufficient adhesive curing can also cause adhesive overflow between the laminated components and the frame of the PV module, resulting in a weak connection. These problems directly affect the effective connection of the PV module, thereby reducing its overall reliability. To address this, the researchers in this application propose a PV module clamp that effectively solves the problem of insufficient bonding between the glass and the laminated components caused by incomplete adhesive curing during the PV module production line.

[0032] like Figure 1 As shown, Figure 1 This is a schematic diagram of the assembled structure of the photovoltaic module and the photovoltaic module fixture according to this application. The photovoltaic module fixture includes a support part 100, a first limiting part 200, and a second limiting part 300, wherein the support part 100 is used to connect the first limiting part 200 and the second limiting part 300, and the first limiting part 200 and the second limiting part 300 are respectively used to fix the opposite sides of the photovoltaic module. In this embodiment, the researchers intend to effectively solve the problem of insufficient connection between the glass 410 and the laminate 420 caused by incomplete curing of the colloid in the photovoltaic module during the production line by using the photovoltaic module fixture.

[0033] Specifically, the support portion 100 extends along a first direction, wherein the first direction can be referred to as... Figure 1 The direction pointed to by the middle arrow a; the first limiting part 200 is provided at one end of the support part 100, and the first limiting part 200 applies force to the surface of the glass 410 of the photovoltaic module to keep the glass 410 and the laminate 420 of the photovoltaic module in contact; the second limiting part 300 extends along a second direction, which can be referred to in the second direction. Figure 1 In the direction pointed to by the middle arrow b, the second limiting part 300 is disposed at the other end of the support part 100 relative to the first limiting part 200, and is located on the same side of the support part 100 as the first limiting part 200. The second limiting part 300 is used to support the frame 430 of the photovoltaic module and to fix and constrain the frame 430.

[0034] In this embodiment, the first limiting part 200 applies force to the surface of the glass 410 of the photovoltaic module, ensuring a tight fit between the glass 410 and the laminate 420 of the photovoltaic module. The second limiting part 300 is located at the other end of the support part 100 and on the same side as the first limiting part 200. The design of the second limiting part 300 extending along a second direction allows it to both support the frame 430 and securely restrain the frame 430. Through the combined action of the first limiting part 200 and the second limiting part 300, the photovoltaic module clamp restrains the opposite sides of the photovoltaic module, ensuring that the photovoltaic module is fixed between the first limiting part 200 and the second limiting part 300. Because the glass 410 and the laminate 420 remain tightly fitted, the risk of separation between the glass 410 and the laminate 420 during the production line can be effectively avoided.

[0035] In one embodiment, see Figure 1 As shown, the first limiting part 200 also forms a limiting space 210, which is used to accommodate the colloid overflowing from between the frame 430 and the laminate 420.

[0036] In this embodiment, the design of the first limiting part 200 forms a limiting space 210, which can accommodate the adhesive overflowing from between the photovoltaic module frame 430 and the photovoltaic module laminate 420. When the photovoltaic module is placed upside down, the overflowing adhesive is effectively contained and covered by the limiting space 210, thereby reducing the impact of adhesive overflow on the connection between the frame 430 and the laminate 420. Through the design scheme in this embodiment, the risk of loose connection between the frame 430 and the laminate 420 due to adhesive overflow is effectively reduced, further improving the connection reliability and overall stability of the photovoltaic module.

[0037] In one embodiment, see Figure 2 As shown, the first limiting part 200 includes a pressing part 220 and a connecting part 230. The connecting part 230 connects the pressing part 220 and the supporting part 100. The pressing part 220 is used to apply pressure to the surface of the glass 410 so that the glass 410 adheres to the laminate 420.

[0038] In this embodiment, the first limiting part 200 includes a pressing part 220 and a connecting part 230, wherein the connecting part 230 connects the pressing part 220 and the supporting part 100 to achieve a stable connection of the structure. The pressing part 220 is used to apply pressure to the surface of the glass 410 of the photovoltaic module, thereby keeping the glass 410 and the laminate 420 of the photovoltaic module in close contact. Through the design scheme in this embodiment, the connection effect between the glass 410 and the laminate 420 is ensured, reducing the problem of loose bonding that may be caused by incomplete curing of the adhesive between the glass 410 and the laminate 420, and improving the connection reliability of the photovoltaic module during use.

[0039] In one embodiment, the connecting portion 230 has an arc-shaped structure and extends obliquely towards the surface of the glass 410. The inner side of the arc-shaped structure forms a limiting space 210 for accommodating the adhesive that overflows from between the frame 430 and the laminate 420.

[0040] In this embodiment, the connecting part 230 is designed as an arc-shaped structure and extends obliquely towards the surface of the photovoltaic module glass 410. The inner side of the arc-shaped structure forms a limiting space 210 to accommodate the colloid overflowing from between the photovoltaic module frame 430 and the photovoltaic module laminate 420, thereby effectively preventing the colloid from overflowing and affecting other components of the photovoltaic module.

[0041] Furthermore, due to the arc-shaped structure and inclined extension design of the connecting part 230, when the photovoltaic module clamp is installed, pulling the connecting part 230 can cause it to deform, and after installation, the connecting part 230 returns to its original state. During the recovery process, the connecting part 230 can drive the pressing part 220 to move towards the surface of the photovoltaic module glass 410, thereby making the pressing part 220 press more tightly against the surface of the photovoltaic module glass 410.

[0042] In one embodiment, see Figures 1 to 3 As shown, the second limiting part 300 has a fixing part 310 at one end away from the support part 100, and the slot 320 formed between the fixing part 310 and the second limiting part 300 is used to engage the extension part 431 of the frame 430.

[0043] In this embodiment, a fixing part 310 is provided at the end of the second limiting part 300 away from the support part 100. The slot 320 formed between the fixing part 310 and the second limiting part 300 can engage the extension part 431 of the frame 430, thereby reducing the risk of the frame 430 detaching from the photovoltaic module fixture.

[0044] In one embodiment, the photovoltaic module clamp is made of an elastic material.

[0045] In this embodiment, the photovoltaic module clamp is made entirely of a deformable elastic material, which can be polycarbonate. Utilizing the properties of the elastic material, the photovoltaic module clamp can adapt to the size requirements of the photovoltaic module through elastic deformation before installation, and after installation, it can elastically recover its deformation and adhere to the surface of the photovoltaic module, thereby achieving stable positioning and fixation of the photovoltaic module.

[0046] In one embodiment, the vertical distance between the fixing part 310 and the pressing part 220 is less than the height of the frame 430, so that the first limiting part 200 and the second limiting part 300 can apply elastic pressure to the frame 430.

[0047] In this embodiment, the vertical distance between the fixing part 310 and the pressing part 220 is less than the height of the photovoltaic module frame 430. This design allows the smaller vertical distance to enable the first limiting part 200 and the second limiting part 300 to fit more tightly against the opposite sides of the photovoltaic module after elastic deformation.

[0048] In one embodiment, see Figure 4 As shown, the first limiting part 200 extends along a third direction, and the extension length of the first limiting part 200 is the same as the length of the photovoltaic module, and the second limiting part 300 is spaced apart along a third direction.

[0049] In this embodiment, the first limiting portion 200 extends along a third direction, wherein the third extending direction can be referred to Figure 4 As shown by arrow c, the extension length of the first limiting part 200 is the same as the length of the photovoltaic module, thereby enabling the first limiting part 200 to apply a uniform force to the surface of the photovoltaic module glass 410, ensuring a stable fit between the glass 410 and the laminate 420. Simultaneously, the second limiting parts 300 are spaced apart along a third direction. This spaced arrangement design provides necessary support and fixation for the photovoltaic module frame 430, while also reducing the material usage and overall weight of the photovoltaic module clamp.

[0050] In one embodiment, the pressing part 220 extends in the third direction for the same length as the first limiting part 200, and the width of the pressing part 220 is less than or equal to 10 centimeters.

[0051] In this embodiment, the extension length of the pressing part 220 in the third direction is consistent with the extension length of the first limiting part 200, so that the pressing part 220 can apply a uniformly distributed force to the surface of the photovoltaic module glass 410, thereby further improving the bonding effect between the photovoltaic module glass 410 and the photovoltaic module laminate 420.

[0052] In addition, the width of the pressing part 220 is limited to less than or equal to 10 cm. This width setting can provide an appropriate pressing area, thereby ensuring that the force applied by the pressing part 220 to the surface of the photovoltaic module glass 410 is both concentrated and evenly distributed, effectively improving the bonding effect between the glass 410 and the laminate 420, and avoiding the problem of pressure force dispersion caused by excessive width.

[0053] In one embodiment, see Figure 2 and Figure 3 As shown, the support part 100 is provided with a through hole 110, which is used to separate the photovoltaic module clamp from the photovoltaic module by external force.

[0054] In this embodiment, when the photovoltaic module clamp completes the fixation and constraint of the photovoltaic module, it is necessary to separate the photovoltaic module clamp from the photovoltaic module. By applying a force to the through hole 110 of the support part 100 in the photovoltaic module clamp, the photovoltaic module clamp can be quickly separated from the photovoltaic module.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
