[0002] A solar panel is an energy converter that converts light energy into electrical energy through a photoelectric reaction. The conversion efficiency of a solar panel is an important factor in reducing the cost of photovoltaic power generation. In traditional solar panel production equipment, a single-laser processing equipment architecture is generally used for processing. However, as the requirements for the photoelectric conversion efficiency of solar panels become higher and higher, the traditional single-laser processing method can no longer meet the need to improve the photoelectric conversion efficiency. Therefore, different laser types are used to perform step-by-step processing on the same solar panel. If two laser types are directly processed on the basis of traditional single-laser processing equipment, two laser processing lines need to be docked and repeatedly loaded and unloaded to meet the requirements of two laser processing steps. This processing method of docking two laser lines not only has a large equipment volume and occupies too much area, but also the process of repeated loading and unloading reduces the overall production efficiency.

[0018] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] As Figures 1 to 3 shown, a four-station laser processing device of the present utility model includes a processing turntable 1, a positioning CCD module 2, a first laser processing module 3, and a second laser processing module 4. The first station, the second station, the third station, and the fourth station are sequentially arranged around the processing turntable 1. The first station is connected to the loading and unloading equipment of the solar panel 6. The positioning CCD module 2 is installed on the second station and aligned with the solar panel 6 on the processing turntable 1. The first laser processing module 3 is installed on the third station and aligned with the solar panel 6 on the processing turntable 1. The second laser processing module 4 is installed on the fourth station and aligned with the solar panel 6 on the processing turntable 1. The processing turntable 1 rotates self-driven and drives the raw material of the loaded solar panel 6 to pass through the visual positioning of the positioning CCD module 2, and then successively passes through the two laser processes of the first laser processing module 3 and the second laser processing module 4 to form the finished product of the solar panel 6 and then unload the material.

[0020] The processing turntable 1 includes a turntable mounting plate 11, a motor 12, a cross-shaped rotating frame 13, an adsorption bracket 14, and an air suction mechanism. The motor 12 is connected to the turntable mounting plate 11, and the output shaft of the motor 12 is connected to the center of the cross-shaped rotating frame 13. Each of the four ends of the cross-shaped rotating frame 13 is provided with a processing platform, and at least one adsorption bracket 14 is arranged on each processing platform. The air suction mechanism is connected to the adsorption bracket 14.

[0021] On the four ends of the cross-shaped rotating frame 13, they all serve as processing platforms for adsorbing the solar panel 6. The positions of the four processing platforms are just aligned with the loading and unloading equipment, the positioning CCD module 2, the first laser processing module 3, and the second laser processing module 4, realizing the synchronous progress of loading and unloading operations, visual positioning, first laser processing, and second laser processing operations. The motor 12 is used to drive the cross-shaped rotating frame 13 to rotate in the direction of the processing sequence, and the rotation angle each time is 90°, ensuring that the solar panel 6 can be accurately aligned with the equipment of the next operation process after each rotation. The air suction mechanism evacuates the suction bracket 14, making the surface of the suction bracket 14 maintain a negative pressure state, so that the solar panel 6 can be firmly adsorbed.

[0022] The suction bracket 14 is of a grid structure, and a plurality of vacuum suction holes are evenly arranged along the grid center line of the suction bracket 14. The overall shape of the suction bracket 14 is grid-shaped, which can not only reduce the overall weight but also maintain a certain strength and rigidity. The grid arrangement is conducive to the rapid dissipation of heat generated by the laser during laser processing, thereby reducing the thermal influence of processing. 1mm vacuum suction holes are opened along the grid center line, and the distance between holes is 10mm, ensuring the uniform distribution of the adsorption force on the surface of the suction bracket 14.

[0023] A vacuum chamber is provided inside the suction bracket 14.

One end of the vacuum air pipe 15 communicates with the vacuum chamber, and the other end of the vacuum air pipe 15 is connected to a vacuum generator and a vacuum detection device through the rotary frame 16.

[0024] When adsorbing the solar panel 6, the vacuum generator evacuates the vacuum chamber of each suction bracket 14 through the vacuum air pipe 15, and adsorbs the solar panel 6 through the vacuum suction holes; the vacuum detection device is used to detect the vacuum degree of each suction bracket 14 to judge whether the solar panel 6 is adsorbed on the suction bracket 14 or whether there is a problem of air leakage in the suction bracket 14.

[0025] The processing turntable 1 includes a laser power meter 17. The laser power meter 17 is connected to the turntable mounting plate 11, and the laser power meter 17 is located below the suction bracket 14. Each laser power meter 17 corresponds to a suction bracket 14 at a laser processing station, and is used to regularly detect the laser power attenuation of the laser. If it exceeds the allowable attenuation value, an alarm is given and the laser power is adjusted.

[0026] The positioning CCD module 2 includes a CCD camera 22 and a CCD bracket 21. The CCD bracket 21 is installed on the second working station, and the CCD camera 22 is connected to the CCD bracket 21. The lens of the CCD camera 22 is aligned with the solar panel 6 placed on the processing turntable 1. The CCD bracket 21 is used to fix the CCD camera 22, so that the CCD camera 22 has a certain visual height to collect the image of the solar panel 6 on the processing turntable 1, thereby positioning the position on the solar panel 6 that needs laser processing.

[0027] The first laser processing module 3 includes a first laser base 31, a first light path generator 32, and a first galvanometer 33. The first laser base 31 is installed on the third working station, the first light path generator 32 is connected to the first laser base 31, the light inlet of the first galvanometer 33 is docked with the first light path generator 32, and the light outlet of the first galvanometer 33 is aligned with the solar panel 6 placed on the processing turntable 1. The first laser base 31 can support the first light path generator 32 and the first galvanometer 33, so that the laser performs laser processing on the solar panel 6 on the processing turntable 1 from top to bottom. The first light path generator 32 of the required laser light type can be selected according to specific processing needs. The laser generated by the first light path generator 32 is projected onto the surface of the solar panel 6 after passing through the first galvanometer 33, realizing the first laser processing.

[0028] The second laser processing module 4 includes a second laser base 41, a second light path generator 42, and a second galvanometer 43. The second laser base 41 is installed on the fourth working station, the second light path generator 42 is connected to the second laser base 41, the light inlet of the second galvanometer 43 is docked with the second light path generator 42, and the light outlet of the second galvanometer 43 is aligned with the solar panel 6 placed on the processing turntable 1.

Marble has a small deformation when heated, which can ensure the stability of the whole machine and avoid deviation in laser processing caused by deformation.

[0030] The working principle of this four-station laser processing device is as follows:

[0031] The loading and unloading equipment places the raw solar panel 6 on the adsorption bracket 14 of the processing turntable 1 at the first station. The vacuum generator evacuates the adsorption bracket 14 through the vacuum pipe 15 so that the solar panel 6 can be fixed. The motor 12 drives the cross-shaped rotating frame 13 to rotate 90°. The solar panel 6 is located below the CCD camera 22. The CCD camera 22 captures the image of the solar panel 6, locates the processing area on the solar panel 6, and then transmits the signal to the first laser processing module 3 and the second laser processing module 4. After positioning, the motor 12 drives the cross-shaped rotating frame 13 to continue rotating 90°. The solar panel 6 is located below the first laser processing module 3. The first light path generator 32 emits laser light, which is projected onto the surface of the solar panel 6 through the first galvanometer 33 for processing. After the first laser processing is completed, the motor 12 drives the cross-shaped rotating frame 13 to continue rotating 90°. The solar panel 6 is located below the second laser processing module 4. The second light path generator 42 emits laser light, which is projected onto the surface of the solar panel 6 through the second galvanometer 43 for processing. After the second laser processing is completed, the motor 12 drives the cross-shaped rotating frame 13 to continue rotating 90° back to the first station. At this time, the loading and unloading equipment transports and unloads the processed solar panel 6, and at the same time places the new raw solar panel 6 on the cross-shaped rotating frame 13 at the first station. There are four processing stations on the cross-shaped rotating frame 13, which can synchronously realize the operations of loading and unloading, visual positioning, first laser processing, and second laser processing of four groups of solar panels 6.
