[0037] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0038] like Figures 1 to 11 As shown, this embodiment provides a photovoltaic module polishing device for polishing the four corners of the photovoltaic module frame. The photovoltaic module polishing device is composed of a frame 1, a horizontal motion mechanism 2 and a polishing mechanism 3.

[0039] Specifically, in the photovoltaic module polishing device, the frame 1 is used to carry the horizontal motion mechanism 2 and the polishing mechanism 3. The frame 1 can be assembled from aluminum alloy according to a certain size. The frame 1 can adopt a hollow design, which can reduce weight and save costs. The horizontal motion mechanism 2 can be fixed to the frame 1 by bolts or other connection methods. The horizontal motion mechanism 2 can carry photovoltaic modules. A polishing mechanism 3 is provided on the horizontal motion mechanism 2, and the polishing mechanism 3 is respectively located at the four corners of the horizontal motion mechanism 2, corresponding to the four corners of the photovoltaic module. The horizontal motion mechanism 2 and the polishing mechanism 3 can limit the position of the photovoltaic module. The polishing mechanism 3 can move horizontally on the horizontal motion mechanism 2 to achieve the purpose of contacting the four corners of the photovoltaic module. After the polishing mechanism 3 contacts the four corners of the photovoltaic module, the four corners of the photovoltaic module can be polished.

[0040] The photovoltaic module polishing device proposed in this embodiment adjusts the position of the polishing mechanism 3 through the horizontal motion mechanism 2 to achieve mechanized polishing of the four corners of the photovoltaic module frame, which can replace manual polishing, effectively improve the polishing effect, and greatly save labor costs and time costs.

[0041] In some optional embodiments, the horizontal motion mechanism 2 includes a first servo motor 2-1, a ball screw shaft 2-2, a screw nut 2-3, a first slide rail 2-4, a second slide rail 2-5, a first slider 2-6, a second slider 2-7, a first beam 2-8 and a second beam 2-9. The first beam 2-8 and the second beam 2-9 are arranged horizontally and in parallel. The grinding mechanism 3 is arranged on the left and right sides of the first beam 2-8 and the second beam 2-9. The first slider 2-6 and the second slider 2-7 are arranged on the left and right sides of the bottom of the first beam 2-8 and the second beam 2-9 respectively. The first slide rail 2-4 is arranged on the two first sliders 2-6. The second slide rail 2-5 is arranged on the two second sliders 2-7. The middle of the bottom of the first beam 2-8 and the second beam 2-9 is provided with a screw nut 2-3. The ball screw shaft 2-2 is arranged on the two screw nuts 2-3. The output shaft of the first servo motor 2-1 is connected to one end of the ball screw shaft 2-2.

[0042] Specifically, the horizontal motion mechanism 2 is placed on the frame 1. The first servo motor 2-1 is connected to the ball screw shaft 2-2, and can provide power support for the rotation of the ball screw shaft 2-2. The ball screw shaft 2-2 rotates under the drive of the first servo motor 2-1, thereby driving the two screw nuts 2-3 to move horizontally on the ball screw shaft 2-2. Since the two screw nuts 2-3 are fixedly connected to the first crossbeam 2-8 and the second crossbeam 2-9, the first crossbeam 2-8 and the second crossbeam 2-9 can also move horizontally synchronously. The first slide rail 2-4 and the second slide rail 2-5 can provide movement directions for the first crossbeam 2-8 and the second crossbeam 2-9.

[0043] In this embodiment, the first slide rail 2-4, the ball screw shaft 2-2 and the second slide rail 2-5 need to be arranged horizontally and parallel to ensure the stability and accuracy of the movement of the first beam 2-8 and the second beam 2-9.

[0044] Furthermore, in this embodiment, the ball screw shaft 2-2 adopts a special-shaped structure. The thread rotation direction of the ball screw shaft 2-2 from the center point to the two ends is opposite. That is, the slotted thread on the ball screw shaft 2-2 is designed as a symmetrical reverse structure. When the ball screw shaft 2-2 rotates, the two screw nuts 2-3 nested on the ball screw shaft 2-2 can move horizontally in opposite directions, thereby realizing that one power source simultaneously drives four groups of grinding mechanisms 3 to move in opposite directions, respectively, to ensure that the displacement distance of the relative movement is consistent and improve the working efficiency.

[0045] Furthermore, in this embodiment, both left and right ends of the first crossbeam 2-8 and the second crossbeam 2-9 are provided with outwardly extending fixed platforms 2-10. The grinding mechanism 3 is fixed on the fixed platform 2-10. Since the grinding mechanism 3 will generate certain vibrations during the grinding process, the mounting surface of the grinding mechanism 3 is enlarged in this embodiment to make the grinding mechanism 3 more stably fixed.

[0046] In some optional embodiments, the grinding mechanism 3 includes a second servo motor 3-1, a driving shaft 3-2, a passive shaft 3-3 and a sand belt 3-4. The driving shaft 3-2 and the passive shaft 3-3 are arranged vertically and parallel. The sand belt 3-4 is sleeved on the driving shaft 3-2 and the passive shaft 3-3. The output shaft of the second servo motor 3-1 is connected to one end of the driving shaft 3-2.

[0047] Specifically, the grinding mechanism 3 is fixed on the fixed platform 2-10 on the left and right sides of the first beam 2-8 and the second beam 2-9 of the horizontal motion mechanism 2. Each group of grinding mechanisms 3 is composed of a second servo motor 3-1, an active shaft 3-2, a passive shaft 3-3 and an abrasive belt 3-4. The active shaft 3-2 and the passive shaft 3-3 are both vertically fixed on the top surface of the fixed platform 2-10. At the position of the active shaft 3-2, the fixed platform 2-10 is provided with a through hole. The output shaft of the second servo motor 3-1 passes through the through hole and is connected to one end of the active shaft 3-2. The second servo motor 3-1 is fixed to the bottom surface of the fixed platform 2-10. The second servo motor 3-1 can provide power for the active shaft 3-2, so that the active shaft 3-2 rotates, thereby driving the abrasive belt 3-4 to move. The abrasive belt 3-4 performs a grinding operation by contacting the four corners of the frame of the photovoltaic module.

[0048] In this embodiment, the sanding belt 3 - 4 is arranged at a certain angle to the frame of the photovoltaic module, so that the sanding belt 3 - 4 can contact the four corners of the frame of the photovoltaic module. The angle can be specifically set to 45°.

[0049] In some optional embodiments, the photovoltaic module polishing device further includes a dust suction mechanism 4. The dust suction mechanism 4 is arranged below the polishing mechanism 3 and is used to clean up the debris generated after the polishing mechanism 3 polishes the photovoltaic module, so as to ensure the cleanliness of the working area, protect the health of the operators and prevent the photovoltaic module from being contaminated by aluminum chips.

[0050] Specifically, the dust collection mechanism 4 includes a central dust collector 4-1, a pipe 4-2 and a suction nozzle 4-3. The central dust collector 4-1 is connected to four pipes 4-2. A suction nozzle 4-3 is provided at the end of each pipe 4-2. The four suction nozzles 4-3 are respectively arranged under the four groups of grinding mechanisms 3 and are fixedly connected to the first crossbeam 2-8 and the second crossbeam 2-9.

[0051] In this embodiment, the central vacuum cleaner 4-1 is placed in the lower part of the center of the frame 1, specifically below the horizontal motion mechanism 2. Four suction nozzles 4-3 are placed directly below the grinding mechanism 3 and fixedly connected to the first crossbeam 2-8 and the second crossbeam 2-9 of the horizontal motion mechanism 2. The four suction nozzles 4-3 can collect aluminum chips generated by the grinding mechanism 3 grinding the photovoltaic module frame under the power drive of the central vacuum cleaner 4-1. The suction nozzle 4-3 is connected to the central vacuum cleaner 4-1 through a pipe 4-2, which is responsible for transporting the collected aluminum chips. The pipe 4-2 can be made of stainless steel.

[0052] Furthermore, a hollow structure design can be adopted in the fixed platform 2-10 area of ​​the first beam 2-8 and the second beam 2-9 between the grinding mechanism 3 and the suction nozzle 4-3, so that the aluminum chips generated by grinding by the grinding mechanism 3 can fall smoothly into the suction nozzle 4-3, and no aluminum chips will accumulate on the fixed platform 2-10.

[0053] The photovoltaic module polishing device of this embodiment can be placed outside the photovoltaic module production line to ensure that the photovoltaic module production line can flow smoothly in the photovoltaic module polishing device. The frame 1 can be used as a medium to receive and carry photovoltaic modules. The photovoltaic modules on the production line can enter the frame 1 through the hollow frame 1 and fall on the horizontal motion mechanism 2. The horizontal motion mechanism 2 and the polishing mechanism 3 can limit the position of the photovoltaic module.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
