[0002] A solar photovoltaic (PV) module frame refers to the aluminum alloy profile frame and bracket that secures the PV solar panel assembly. It is used to fix and seal the solar panel, enhance its strength, extend its lifespan, and facilitate transportation and installation. The PV module frame profiles need to be sawn into frame parts. During the sawing process, profile positioning fixtures are often required. However, traditional fixtures are prone to profile vibration during sawing, affecting the flatness and angular accuracy of the cut surface. Furthermore, when switching between long and short frame profiles, corresponding fixtures need to be changed, requiring equipment downtime for replacement, which is time-consuming and labor-intensive. Utility Model Content
[0003] The purpose of this utility model is to provide a sawing fixture for solar photovoltaic module frame profiles to solve the above problems. It is convenient and quick to clamp, reliable in positioning, and highly accurate. Moreover, the sawing fixture can be used for both long and short frames, reducing equipment downtime and fixture replacement time, and improving profile sawing efficiency.
[0004] Technical Solution: This utility model provides a sawing fixture for solar photovoltaic module frame profiles, including a sawing fixture body, which is integrally formed. A first support portion and a second support portion are provided on the upper part of the sawing fixture body. A first clearance groove is provided between the first and second support portions to avoid the laminate support surface of the photovoltaic module frame. A second clearance groove is provided on the outer side of the second support portion to avoid the short side surface of the photovoltaic module frame. A short frame support portion is provided in the middle of the outer side of the first support portion, and a long frame support portion is provided at the lower part. The sawing fixture structure matches the photovoltaic module frame profile, making the profile positioning surface more reliable, reducing profile vibration during sawing, and resulting in higher flatness and precision of the sawed surface.
[0005] Furthermore, in the aforementioned solar photovoltaic module frame profile sawing fixture, the main cutting surface of the sawing fixture is designed with an inclination angle that is consistent with the exit angle of the saw blade of the sawing machine. This ensures reliable and feasible clamping of the profile being sawn, improves the service life of the saw blade, and reduces saw blade damage and replacement time.
[0006] Furthermore, in the aforementioned solar photovoltaic module frame profile sawing fixture, the upper part of the first support portion is provided with a groove, which can avoid the protruding part inside the photovoltaic module frame.
[0007] Furthermore, in the aforementioned solar photovoltaic module frame profile sawing fixture, the width of the first support part is greater than that of the second support part, both of which are used to support the inner wall of the photovoltaic module frame and adapt to the shape of the photovoltaic module frame.
[0008] Furthermore, in the aforementioned sawing fixture for solar photovoltaic module frame profiles, the first clearance groove and the second clearance groove have equal depths, making the fixture more versatile.
[0009] Furthermore, in the aforementioned solar photovoltaic module frame profile sawing fixture, the protruding dimension of the short frame support is smaller than that of the long frame support. This fixture can be used for both short and long frame profiles, reducing the replacement time of traditional profile fixtures, reducing equipment downtime and fixture replacement time. The wider long frame support can accommodate long frame profiles of different sizes.
[0010] Furthermore, in the aforementioned solar photovoltaic module frame profile sawing fixture, the height of the main body of the sawing fixture is greater than or equal to the width of the longest side of the photovoltaic module frame profile, ensuring that the photovoltaic module frame profile can be clamped onto the fixture.
[0011] As can be seen from the above technical solution, the present invention has the following beneficial effects: The solar photovoltaic module frame profile sawing fixture described in the present invention has a structural design that conforms to the photovoltaic module frame profile, making clamping convenient and quick, the profile positioning surface more reliable, the profile less prone to shaking during sawing, and the flatness and precision of the sawing surface are higher. The tilt angle is consistent with the exit angle of the saw blade of the sawing machine, the clamping of the sawed profile is reliable and feasible, the service life of the saw blade is improved, the saw blade damage and replacement time is reduced, and it can be used for short frame profiles and long frame profiles, reducing the replacement time of traditional profile fixtures, reducing equipment downtime and fixture replacement time, reducing costs, and the wider long frame support can adapt to long frame profiles of different sizes.

[0018] Example 1
[0019] like Figure 1-2 The illustrated solar photovoltaic module frame profile sawing fixture includes: a sawing fixture body 1, which is integrally formed; a first support part 11 and a second support part 12 are provided on the upper part of the sawing fixture body 1; a first clearance groove 13 is provided between the first support part 11 and the second support part 12 to avoid the laminate support surface of the photovoltaic module frame; a second clearance groove 14 is provided on the outer side of the second support part 12 to avoid the short side surface of the photovoltaic module frame; a short frame support part 15 is provided in the middle of the outer side of the first support part 11, and a long frame support part 16 is provided at the lower part. The sawing fixture structure matches the photovoltaic module frame profile, making the profile positioning surface more reliable, reducing profile vibration during sawing, and improving the flatness and precision of the sawed surface.
[0020] like Figure 1 , 3 -5 shows a sawing fixture for solar photovoltaic module frame profiles. The main body 1 of the sawing fixture has an inclined cutting surface with an inclination angle that matches the exit angle of the saw blade of the sawing machine. This ensures reliable and feasible clamping of the profiles to be sawed, improves the service life of the saw blade, and reduces saw blade damage and replacement time.
[0021] like Figure 2 The above describes a sawing fixture for a solar photovoltaic module frame profile. The first support part 11 has a groove on its upper part, which can avoid the protruding part inside the photovoltaic module frame.
[0022] Example 2
[0023] Based on Example 1, in this example, as... Figure 2 The above describes a sawing fixture for solar photovoltaic module frame profiles. The width of the first support part 11 is greater than that of the second support part 12, both of which are used to support the inner wall of the photovoltaic module frame and adapt to the shape of the photovoltaic module frame. The depths of the first clearance groove 13 and the second clearance groove 14 are equal, making the fixture more versatile.
[0024] like Figure 3-5The above describes a sawing fixture for solar photovoltaic module frame profiles. The protruding part of the short frame support 15 is smaller than that of the long frame support 16. This fixture can be used for both short and long frame profiles, reducing the replacement time of traditional profile fixtures and the downtime of equipment and fixture replacement. The wider long frame support 16 can accommodate long frame profiles of different sizes.
[0025] In this embodiment, the height of the sawing fixture body 1 is greater than or equal to the width of the longest side of the photovoltaic module frame profile, ensuring that the photovoltaic module frame profile can be clamped on the fixture.
[0026] In this embodiment, the main body 1 of the sawing fixture is set on the sawing machine platform when in use. The outer side of the second support part 12 is close to the lateral reference surface of the sawing machine. After the photovoltaic module frame profile is placed on the fixture, the two sides of the photovoltaic module frame profile are fixed by the cylinder. The saw blade extends and performs the sawing action. After the sawing is completed, the saw blade is retracted, the cylinder is retracted, the frame parts are taken out, and the profile is fed in for continuous sawing production.
[0027] In this embodiment, two sawing fixture bodies 1 are used on a double-head sawing machine, and the two sawing fixture bodies 1 are symmetrically arranged on the sawing machine platform.
