[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] In the processing of photovoltaic silicon materials, photovoltaic laser processing equipment requires repeated processing at high frequency over long periods. After a period of use, due to external disturbances or fatigue loosening, the reflector is prone to a certain degree of displacement, resulting in deviations in the optical path. Therefore, the reflector needs to be adjusted and corrected. Existing reflectors are placed in a single reflector box, which provides excellent sealing. However, because the entire box is sealed, the reflector angle cannot be directly adjusted. Furthermore, the reflector box is too large and its position is very close to other components, making disassembly extremely inconvenient. Disassembly tools are unavailable, so the outer casing and surrounding components must be removed before the reflector box can be disassembled.
[0028] To address at least one of the aforementioned problems, the present invention provides a photovoltaic laser reflector 1, applied to photovoltaic laser processing equipment. Laser light emitted from a laser generator 2 travels through a lens barrel 3 to the reflector 1, where it is reflected and then transmitted back out through the lens barrel 3. The reflector 1 includes a mirror body 11, a frame 12, and an adjustment device 13.
[0029] The mirror body 11 includes a lens 111 for reflecting laser light and an assembly 112 for mounting the lens 111. The assembly 112 is used to determine the position and orientation of the lens 111. By changing the orientation and tilt angle of the assembly 112, the reflection angle of the lens 111 can be adjusted, thereby changing the reflection path of the laser light. The tilt angle of the assembly 112 can be adjusted within the range of -5 to 5 degrees.
[0030] The frame 12 includes a laser entrance aperture and an exit aperture, and a mirror cavity 121 for accommodating the lens 111 and the assembly 112. The mirror cavity 121 includes a reflection cavity and an adjustment cavity. The frame 12 is a hollow structure. In a preferred embodiment of this invention, the frame 12 is a polygonal structure, comprising an isosceles right-angled triangle and an isosceles trapezoid. The hypotenuse of the isosceles right-angled triangle is equal in length to and connected to the base of the isosceles trapezoid. The hollow interior of the isosceles right-angled triangle forms a reflection cavity, which serves as the path for laser incident and reflected light. An entrance aperture is disposed on one right-angled side of the isosceles right-angled triangle, and an exit aperture is disposed on the other right-angled side. The hollow interior of the isosceles trapezoid forms an adjustment cavity, in which the lens 111 and the assembly 112 are disposed. The adjustment cavity is used to accommodate the mirror 11 and for angle adjustment.
[0031] This invention abandons the original large mirror box design and replaces it with a compact mirror frame 12 structure. The mirror tube 3 is directly connected to the entrance and exit holes of the mirror frame 12, significantly reducing the size of the reflector module 1 without changing the original optical path, thus providing sufficient space for adjustment and disassembly. This invention designs a polygonal mirror frame 12 to form a mirror cavity 121 that can simultaneously accommodate the reflected light path and the mirror body 11. The mirror body 11 is directly sealed inside the mirror cavity 121, which can isolate it from dust and moisture contamination.
[0032] The adjustment device 13 includes an adjustment plate 131 and an adjustment component. The adjustment device 13 is adjustablely configured on the mirror frame 12. The adjustment component adjusts the laser emission angle by changing the angle between the assembly 112 and the adjustment plate 131.
[0033] In a preferred embodiment of this utility model, the adjusting device 13 includes an adjusting plate 131 and a plurality of adjusting members. The adjusting plate 131 is mounted on the top edge of the isosceles trapezoid and has a plurality of adjusting holes, including a first adjusting hole 134 and a second adjusting hole 135. In a preferred embodiment of this utility model, the adjusting members include a first adjusting member 132 and a second adjusting member 133. At least two first adjusting members 132 are included; the illustration shows two, but this does not mean that there can only be two. The first adjusting member 132 passes through the first adjusting hole 134 and is hinged to the assembly 112, generating a tensile force between the assembly 112 and the adjusting plate 131. The second adjusting hole 135 is a threaded hole, and the second adjusting member 133 passes through the second adjusting hole 135 and abuts against the assembly; any three second adjusting holes 135 are not collinear. At least three second adjusting members 133 are included, generating a thrust force between the assembly 112 and the adjusting plate 131.
[0034] Specifically, the first adjusting member 132 includes a T-shaped body and a spring sleeved on the T-shaped body, the end of the T-shaped body being hinged to the assembly; the first adjusting hole 134 is a through hole with a step, and the spring is engaged on the step of the through hole.
[0035] Specifically, the second adjusting member 133 includes an adjusting part, a threaded part, and an abutting part. The threaded part is used to engage with the internal thread of the second adjusting hole 135, the abutting part is used to abut against the assembly, and the adjusting part is used to drive the whole to rotate.
[0036] This invention employs two adjusting components to adjust the reflector 1. One adjusting component generates a pulling force between the assembly 112 and the adjusting plate 131, simultaneously controlling the adjustment range of the reflector 1. The other adjusting component generates a pushing force between the assembly 112 and the adjusting plate 131, and simultaneously changes the tilt angle of the assembly 112 and the adjusting plate 131 through the rotation and extension principle of the lead screw. In this design, all adjustments to the reflector 1 are performed directly within the sealed mirror cavity 121 by the adjusting device 13, ensuring overall sealing while reducing the operational difficulty of adjusting the mirror 111. This configuration is simple in structure, combining sealing with good adjustment range.
[0037] In a preferred embodiment of this utility model, a protective cover plate 122 is also included. The protective cover plate 122 is configured to cover the adjusting plate 131, and the protective cover plate 122 is connected to the adjusting plate 131 by screws. Providing a cover plate 122 on the outside of the adjusting plate 131 avoids disturbances such as bumps and accidental operation, reduces loosening, and further enhances the sealing performance.
[0038] The present invention also provides a photovoltaic laser reflector 1 assembly, wherein the photovoltaic laser reflector 1 assembly includes the photovoltaic laser reflector 1 described in any of the above claims.
