Description

Technical Field

[0002] Laser cutting machines generate a high-power-density laser beam, which is focused by a lens and irradiates the material surface. The material absorbs the laser energy and melts or vaporizes instantly, while high-pressure auxiliary gas blows away the molten slag, creating a kerf. Essentially, it utilizes the high brightness, high directionality, and high monochromaticity of lasers to achieve non-contact, precise processing.

[0003] However, when processing photovoltaic bracket steel, existing laser cutting machines typically use rollers to clamp the bracket on both sides to facilitate pushing the bracket. However, this fixing method may cause the bracket to slide due to impact during cutting, thereby causing the cut or hole position to shift and reducing processing accuracy.

[0004] Therefore, this utility model proposes a laser cutting machine for processing photovoltaic bracket steel. Utility Model Content

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figure 1-4As shown in the figure, this utility model provides a laser cutting machine for processing photovoltaic bracket steel, including a base 1, a fixing component 2, and a cutting component 3. The fixing component 2 is disposed on the base 1 and is used to fix the photovoltaic bracket; the fixing component 2 includes two rotating rollers 212, a clamping component, a pressing component, and a rotating component; the clamping component drives the two rotating rollers 212 to move closer to each other to clamp the photovoltaic bracket; the pressing component presses against the four corners of the photovoltaic bracket; the rotating component drives the two rotating rollers 212 to rotate. The cutting component 3 is disposed on the base 1 and is used to cut the photovoltaic bracket; the cutting component 3 includes a support frame 31 fixedly disposed on the base 1; a cylinder 32 is provided at the upper end of the support frame 31; a laser generator 33 is connected to the telescopic end of the cylinder 32.

[0029] Further explanation: The rotating component includes a mounting ring 21 positioned above the base 1; teeth 24 are evenly distributed on the outer side of the mounting ring 21; a fixing frame 22 is fixedly mounted on the base 1; a motor 220 is mounted on the fixing frame 22; a gear 23 is connected to the drive end of the motor 220; the gear 23 is rotatably connected to the fixing frame 22; the gear 23 meshes with the teeth 24. An annular slide rail 25 is fixedly mounted on the base 1; the mounting ring 21 is slidably positioned within the annular slide rail 25. The photovoltaic support can be rotated to cut it from different angles.

[0030] Further explanation: Two sets of clamping components are provided within the mounting ring 21; the two sets of clamping components are perpendicular to each other. They can limit the photovoltaic bracket from both the lateral and longitudinal directions. The clamping components include four fixing blocks 26 fixedly disposed on the inner wall of the mounting ring 21; the four fixing blocks 26 are respectively arranged at the four corners of the mounting ring 21; a bidirectional lead screw 28 is rotatably connected between two fixing blocks 26 on one side, and a slide rod 29 is provided between two fixing blocks 26 on the other side; one fixing block 26 is also equipped with a motor 27; the drive end of the motor 27 is connected to one end of the bidirectional lead screw 28. Two sliders 210 are respectively provided on the bidirectional lead screw 28 and the slide rod 29; the bidirectional lead screw 28 is threadedly connected to the two sliders 210; the slide rod 29 is slidably connected to the two sliders 210; a rotating roller 212 is rotatably connected between the two sliders 210 on the bidirectional lead screw 28 and the slide rod 29; one slider 210 is equipped with a motor 211; the drive end of the motor 211 is connected to one end of the rotating roller 212. Two controllable rotating rollers 212 can be brought closer together to clamp the photovoltaic bracket, maintaining its stability during cutting. Starting motor 211 drives the rotating rollers 212 to rotate, allowing the photovoltaic bracket to move forward or backward for cutting at different positions.

[0031] Further explanation: The pressing component includes multiple springs 214; each spring 214 is sleeved on the outside of the rotating roller 212; each spring 214 is connected to a corresponding slider 210, and the other end of each spring 214 is connected to a pressure plate 215; a pressure plate 218 is fixedly mounted on the end of the pressure plate 215 away from the corresponding spring 214. The springs 214 can push the pressure plates 215 and 218 to press against the four corners of the photovoltaic bracket, further limiting the position of the photovoltaic bracket. A through hole 216 is provided on the pressure plate 215; a second protrusion 217 is evenly provided on the inner wall of the through hole 216; a first protrusion 213 is evenly provided on the side wall of the rotating roller 212; the first protrusion 213 and the second protrusion 217 engage with each other. The first protrusion 213 increases friction and prevents the photovoltaic bracket from slipping. The second protrusion 217 engages with the first protrusion 213, guiding the movement of the pressure plate 215. Both pressure plate 215 and pressure plate 218 are evenly distributed with protrusions 219, which can further increase the friction.

[0032] The clamping and pressing components work together to fix the photovoltaic bracket, offsetting vibrations or impacts during cutting and punching, preventing bracket slippage, and ensuring the positional accuracy of cuts or holes. The pressing components, through spring 214, push pressure plates 215 and 218 to tightly press against the four corners of the bracket, forming multi-point fixation, evenly distributing pressure, reducing localized stress concentration, and thus protecting the integrity of the bracket. Furthermore, spring 214 ensures that pressure plates 215 and 218 remain firmly against the bracket surface, preventing processing errors caused by insecure fixing.

[0033] To further explain, the base 1 is provided with a material trough 101; the material trough 101 is located directly below the laser generator 33. The material trough 101 can collect the cut material.

[0034] The working principle of this utility model is as follows: During operation, the photovoltaic bracket is first placed between two rotating rollers 212. Then, motor 1 27 is started to drive the bidirectional lead screw 28 to rotate, causing the two rotating rollers 212 to move closer together and clamp the bracket. At the same time, spring 214 pushes pressure plate 1 215 and pressure plate 218 to press tightly against the bracket surface, further limiting the bracket's position. Finally, cylinder 32 and laser generator 33 are started to cut the bracket. The cut material falls into the material trough 101 for unified collection. Motor 3 220 is started to drive gear 23 to rotate, thereby driving mounting ring 21 to rotate, which can control the rotation of the photovoltaic bracket to cut it from different angles. Motor 2 211 is started to drive rotating roller 212 to rotate, which can drive the photovoltaic bracket forward or backward to cut different positions of the bracket.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
