Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module frames, and particularly relates to a fixture for a profile of a photovoltaic module frame. Background Art

[0002] In a solar photovoltaic module, a laminate including a solar cell is sealed and fixed by a photovoltaic module frame. The functions of the module frame are to enhance the mechanical strength of the module, seal the edge of the module laminate, and fix the module on a bracket through the frame. The strength of the module frame determines the overall strength of the solar photovoltaic module.

[0003] The profile that constitutes the photovoltaic module frame is an object with a certain geometric shape made of a material with a certain strength and toughness through processes such as rolling, extrusion, and casting. Generally, three of the four sides of the profile are flat, and the other side is an inlay surface. The inlay surface needs to inlay the laminate including the solar cell, so the inlay surface is irregular, and openings for inlaying are provided on this side. When processing the profile, traditional fixtures are generally used to clamp both sides of the inlay surface of the profile. However, since the external forces borne by different positions of the profile are different, and there are openings on the inlay surface, this causes deformation or even tearing to easily occur at some positions of the profile.

[0004] Based on the above situation, the utility model provides a fixture for a profile of a photovoltaic module frame, which can effectively solve one or more of the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fixture for a profile of a photovoltaic module frame.

A clamping device is provided on the cover plate, and the positioning of the profile of the frame in the horizontal direction can be realized through the clamping device.

[0008] Preferably, a positioning groove is provided on the base corresponding to each accommodation cavity, and the positioning groove is at least a part of the accommodation cavity.

However, it should be understood that the drawings are only for illustrative purposes and cannot be construed as a limitation of this patent; to better illustrate this embodiment, some components in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0022] Embodiment 1:

[0023] As Figures 1 to 4 shown, the present utility model provides a fixture for the frame profile of a photovoltaic module, including a base 1 and a cover plate 2 arranged above the base 1. At least one accommodation cavity 3 for accommodating the frame profile 9 is formed between the base 1 and the cover plate 2. A positioning structure 5 is connected to the cover plate 2, and the positioning structure 5 can limit the distance between the cover plate 2 and the base 1, so that the frame profile 9 can be positioned in the vertical direction through the base 1 and the cover plate 2; a clamping device 4 is provided on the cover plate 2, and the frame profile 9 can be positioned in the horizontal direction through the clamping device 4.

[0024] In this application, the number of the accommodation cavities 3 is two.

[0025] In this application, the frame profile 9 is positioned in the vertical direction through the cooperation of the base 1 and the cover plate 2, and the frame profile 9 is positioned in the horizontal direction through the clamping device 4, so that the frame profile 9 is clamped and fixed in the accommodation cavity 3, having a good clamping effect; and the frame profile 9 is clamped by the forces in the horizontal and vertical directions at the same time, making the force on the frame profile 9 more uniform, the force in a single direction reduced, and better ensuring that the frame profile 9 will not be deformed during clamping.

[0026] Preferably, a positioning groove 11 is provided on the base 1 corresponding to each accommodation cavity 3, and the positioning groove 11 is at least a part of the accommodation cavity 3.

[0027] Further, a support member 12 is provided at the bottom of the positioning groove 11, and the support member 12 can abut against the bottom surface of the frame profile 9.

[0028] Since the bottom surface of the frame profile 9 is irregular in shape, if the bottom surface of the frame profile 9 is directly in contact with the bottom surface of the accommodation cavity, it may cause uneven force on the bottom surface of the frame profile 9 during clamping, and then cause deformation of the bottom surface of the frame profile 9. Therefore, in this application, a support member 12 is provided on the bottom surface of the positioning groove 11, and the bottom surface of the frame profile 9 is uniformly stressed through the support member 12.

[0029] In this embodiment, at least the top surface of the support member 12 fits with the bottom surface of the frame profile 9, and the material of the support member has good compressive capacity. By increasing the stress area of the frame profile 9, deformation of the frame profile 9 during clamping is avoided, ensuring a good clamping effect.

[0030] In another embodiment, the material of the support member 12 is an elastomer such as silicone. It will deform during compression and fit with the bottom surface of the frame profile 9, thereby increasing the stress area of the frame profile 9, avoiding deformation of the frame profile 9 during clamping, and ensuring a good clamping effect.

[0031] As Figure 2 and 4 shown, in yet another embodiment, a fluid cavity 121 is provided in the support member 12. A fluid is contained in the fluid cavity 121. A plurality of lifting ports communicating with the fluid cavity 121 are provided at the top of the support member 12. Each lifting port extends downward to form a lifting tube 123, and the bottom end of the lifting tube 123 communicates with the fluid cavity 121; a lifting rod 124 is movably connected in the lifting tube 123, and the top end of the lifting rod 124 is connected to a support plate 125; when the support member 12 is not stressed, the bottom end of the lifting rod 124 is located in the middle of the lifting tube 123. At this time, the fluid fills the fluid cavity 121 and the part of the lifting tube 123 below the lifting rod 124; when the bottom surface of the frame profile 9 acts on the support member 12, the lifting rods 124 at different positions will adjust their heights to fit with the bottom surface of the frame profile 9, and can adapt to a plurality of frame profiles 9 with different bottom surfaces; the fluid can be a liquid or a gas. Since the molecular spacing of the gas is relatively large and the compressibility is good, the fluid is preferably a liquid; using the support plate 125 can increase the contact surface with the frame profile 9 and avoid deformation of the frame profile 9 at the contact position.

[0032] Preferably, adjustment holes 21 communicating with the corresponding accommodation cavities 3 are provided on the top surface of the cover plate 2 corresponding to each accommodation cavity 3. The clamping device 4 includes a moving member 41 and a driving member 42 for driving the moving member 41 to move. A clamping block 43 is provided in each adjustment hole 21. The top end of the clamping block 43 is connected to the moving member 41. The bottom end of the clamping block 43 is located below the cover plate 2, and one side of the clamping block 43 can abut against the side surface of the frame profile 9.

[0033] The driving member can be one or a combination of a cylinder, a linear motor, a ball screw structure, and a crank-slider structure.

[0034] Further, at least a part of the projection of the adjustment hole 21 on the horizontal plane coincides with the projection of the accommodation cavity 3 on the horizontal plane, and a part of the projection of the accommodation cavity 3 on the horizontal plane does not coincide with the projection of the adjustment hole 21 on the horizontal plane.

[0035] In this embodiment, one side of the frame profile 9 abuts against the side surface of the clamping block 43, and the other side abuts against the side surface of the positioning groove 11, which can not only ensure a good clamping effect, but also has a simple structure and reduces the production cost of the fixture.

[0036] As Figure 3 shown, in another embodiment, a fixing block 44 is further provided in each accommodation cavity 3. The top end of the fixing block 44 is connected to the cover plate 2, and one side of the fixing block 44 close to the clamping block 43 can abut against one side of the frame profile 9, and the other side of the frame profile 9 abuts against the side surface of the clamping block 43.

[0037] Preferably, a positioning plate 22 is connected to one side of the cover plate 2, and one side of the positioning plate 22 abuts against the base 1.

[0038] Through the positioning plate 22, the relative position between the cover plate 2 and the base 1 can be limited, ensuring a high clamping accuracy for the frame profile 9 and reducing the matching difficulty with the gas equipment.

[0039] Preferably, the positioning structure 5 is a cylinder, and the cover plate 2 and the cylinder are connected through a connecting member.

[0040] Through the cylinder, it has a fast reaction speed and can improve the clamping effect on the premise of ensuring the clamping effect; in other embodiments, the positioning structure can also be a combination of one or more of a cylinder, a linear motor, a ball screw structure, and a crank-slider structure.

[0041] According to the description and drawings of the present invention, those skilled in the art can easily manufacture or use the fixture for the frame profile of the photovoltaic module of the present invention and can produce the positive effects recorded in the present invention.
