[0018] Please see Figures 1 to 6This invention relates to a milling device for photovoltaic modules in some embodiments, comprising a transmission mechanism 1, a milling mechanism 2 movably connected to the transmission mechanism 1, and a guide driver 3 for driving the milling mechanism 2 to perform horizontal movement. The milling mechanism 2 includes a milling mounting frame 21, a milling connecting frame 22, a milling lifting driver 23, a milling action driver 24, a milling cutter 25, a dust extraction squeegee 26, a roller brush 27, a cleaning connecting frame 201, and a cleaning lifting driver 202. The milling connecting frame 22 is movably connected to the milling mounting frame 21 via a guide rail slider. The milling lifting drive 23 is used to drive the milling connecting frame 22 to move up and down. The milling action drive 24 is mounted on the milling connecting frame 22 and is used to drive the milling cutter 25 to rotate. The cleaning lifting drive 202 is mounted on the milling mounting frame 21 and is used to drive the cleaning connecting frame 201 to move up and down. The dust suction squeegee 26 and the roller brush 27 are both mounted on the cleaning connecting frame 201. The dust suction squeegee 26 and the roller brush 27 are used together to sweep and collect the milling debris.

[0019] The transmission mechanism 1 is equipped with a guide rail slider for mounting the milling mechanism 2. The guide driver 3 is specifically a servo motor, which drives the milling mechanism 2 to move horizontally along the length of the transmission mechanism 1. The milling lifting driver 23 is specifically a servo motor-driven screw jack, whose core structure includes a servo motor, lifting screw, transmission shaft, and commutator. It uses a servo motor as the power source, connects to the transmission shaft via a coupling, and works with the commutator to achieve synchronous rotation of the lifting screws on both sides, ensuring smooth lifting and lowering of the milling connecting frame 22 along the guide rail slider. The milling action driver 24 is specifically a high-speed servo motor, which drives the milling cutter 25 to rotate at high speed to remove broken glass or silicon wafers from the surface of the photovoltaic module. The cleaning lifting driver 202 is specifically a cylinder, which drives the cleaning connecting frame 201, the vacuum cleaner squeegee 26, and the roller brush 27 to lift and lower.

[0020] Understandably, this milling device for photovoltaic modules can mill broken glass or silicon wafers on photovoltaic modules. By setting up a transmission mechanism 1, a milling mechanism 2, and a guide driver 3, the milling device achieves stable transmission and precise milling of photovoltaic modules. The cooperation between the guide rail slider and the milling lifting driver 23 in the milling mechanism 2 can precisely control the lifting of the milling cutter 25 to adapt to different milling height requirements of the photovoltaic modules and ensure consistent milling depth. The combined design of the dust suction squeegee 26 and the roller brush 27 can simultaneously complete the cleaning and adsorption of debris after milling, avoiding debris residue, improving equipment cleanliness and subsequent operational stability. The overall structure is compact, and the components work together to significantly improve the removal efficiency of broken glass or silicon wafers.

[0021] like Figure 5 and Figure 6As shown, there are multiple milling actuators 24, arranged in two rows on both sides of the milling connecting frame 22. Distributing the multiple milling actuators 24 in two rows completely covers the entire area in the width direction of the photovoltaic module, avoiding milling blind spots and ensuring that no broken glass is missed. Simultaneously, the arrangement of multiple milling actuators 24 disperses the milling load, extends the service life of each individual actuator 24, and improves the overall milling efficiency and stability of the equipment. In this embodiment, the milling connecting frame 22 is raised and lowered by lifting screws on both sides to control the milling depth. The lifting screws are connected by a drive shaft and a commutator to ensure synchronous raising and lowering on both sides. The milling connecting frame 22 is machined with positioning grooves to facilitate the positioning of the milling actuators 24 during installation.

[0022] like Figure 6 As shown, a flattening positioning plate 28 is provided between each adjacent milling actuator 24, and guide portions 281 are provided on both sides of the flattening positioning plate 28. The flattening positioning plate 28 between adjacent milling actuators 24 can press and flatten the photovoltaic module during milling, preventing bending and deformation of the photovoltaic module that would lead to uneven milling depth and ensuring milling effect. The design of the guide portions 281 on both sides can guide the photovoltaic module smoothly through the area under the milling cutter 25, avoiding jamming or collision between the photovoltaic module and the flattening positioning plate 28 during transmission, thus improving transmission smoothness.

[0023] The milling device also includes a vacuum cleaner, which is connected to a suction nozzle 26 via a suction pipe. A suction control valve is installed on the suction pipe. The vacuum cleaner and suction nozzle 26 are connected via the suction pipe, and the suction control valve allows for flexible control of suction start / stop and suction power, adapting to the debris cleaning needs under different milling conditions. In this embodiment, there are two suction nozzles 26 and two roller brushes 27, distributed on both sides of the milling connecting frame 22, used to sweep and collect milled debris. The suction nozzle 26 and roller brushes 27 are 1150mm long, covering the width of the photovoltaic module. The suction nozzle 26 is connected to the vacuum cleaner, ensuring sufficient suction power. This vacuum cleaner can be an industrial vacuum cleaner with a power of 7.5kW and a pulse dust removal function. A suction control valve is installed on the suction pipe, allowing for manual or automatic control of material discharge. A wheeled receiving cylinder can be installed at the discharge port, allowing the receiving cylinder to be removed for material transfer after discharge.

[0024] like Figures 2 to 4As shown, the transmission mechanism 1 includes a support base 11, a platform lifting driver 12, a transmission connecting frame 13, a transmission platform 14, and a transmission belt 16. The platform lifting driver 12 is mounted on the support base 11, and its output end is connected to the transmission connecting frame 13. The transmission platform 14 is mounted on the support base 11, and the transmission belt 16 is mounted on the transmission connecting frame 13. The platform lifting driver 12 drives the transmission connecting frame 13 and the transmission belt 16 to move up and down. In the transmission mechanism 1, the platform lifting driver 12 can drive the transmission connecting frame 13 and the transmission belt 16 to move up and down, achieving precise matching of the height of the transmission belt 16 with the belt of the front-end equipment, thus improving the versatility of the equipment. The support base 11 provides stable support for the entire transmission mechanism 1, ensuring that the platform does not shake during transmission and improving the positioning accuracy of the photovoltaic module transmission. The platform lifting driver 12 is preferably a cylinder.

[0025] like Figure 2 As shown, the transmission platform 14 is equipped with multiple vacuum suction cups 15, which can adsorb and fix the photovoltaic modules before milling, preventing the photovoltaic modules from shifting during milling and ensuring precise milling position. Simultaneously, the vacuum adsorption method does not damage the module surface, avoiding the deformation or scratches caused by traditional mechanical clamping, and protecting the integrity of the solar panel and backsheet. In this embodiment, there are six groups of vacuum suction cups 15, each group performing vacuum adsorption control independently.

[0026] The transmission mechanism 1 also includes a belt drive motor 17, which is mounted on the transmission connection frame 13. The belt drive motor 17 drives the transmission belt 16. The cooperation between the transmission belt 16 and the belt drive motor 17 enables automated transmission of photovoltaic modules, replacing manual handling and reducing labor costs. The transmission belt 16 adopts a double-row belt structure, with one belt drive motor 17 driving two transmission belts 16 to move synchronously.

[0027] like Figure 3 As shown, the transmission mechanism 1 also includes a receiving trough 18 installed on the support base 11. The receiving trough 18 can collect broken glass that falls during the milling process, preventing the broken glass from scattering into the equipment or on the ground, and facilitating subsequent centralized processing. The broken glass that falls during the milling process can fall into the receiving trough 18 from the installation gap between the transmission belt 16 and the transmission platform 14.

[0028] The transmission mechanism 1 also includes a stop actuator 19 mounted on the transmission platform 14. The stop actuator 19 can extend and position the photovoltaic module when it is transmitted to a specific position. In conjunction with the laser sensor, it can achieve precise positioning of the module, ensuring that the position of the photovoltaic module on the transmission platform 14 is consistent each time. This provides a basis for the precise milling of the subsequent milling mechanism 2 and avoids milling errors caused by positioning deviations. The stop actuator 19 is preferably a cylinder.

[0029] The bottom of the support base 11 is equipped with multiple adjusting screws 10. The height and level of the support base 11 can be finely adjusted by rotating the adjusting screws 10, ensuring that the overall level of the transmission platform 14 is maintained, and further improving the stability of equipment operation and milling accuracy.

[0030] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
