"Inside" and "outside" refer to the inside and outside relative to the contours of each component. The present invention provides a device for cleaning foreign matter on the surface of photovoltaic glass. Figure 1 and Figure 2 As shown, it includes a frame 1 and also includes:

[0037] Support columns 2, the support columns 2 are arranged below the frame 1 at intervals;

[0038] An adjustment component 6, the adjustment component 6 is arranged on the support column 2, and is used to fix and control the movement of the photovoltaic glass 7 so that foreign matter on the surface of the photovoltaic glass 7 falls off;

[0039] A transport assembly is disposed on the support column 2 and is used for transferring the photovoltaic glass 7 to the adjustment assembly 6 .

[0040] The foreign matter cleaning device of the utility model is provided with a conveying assembly under the frame 1, so that the photovoltaic glass 7 can be transferred between the glass storage place and the adjustment assembly 6, and through the cooperation between the conveying assembly and the adjustment assembly 6, the adjustment assembly 6 fixes the glass transferred by the conveying assembly and moves the photovoltaic glass 7, so that foreign matters on the surface of the photovoltaic glass 7 fall off.

[0041] In the present utility model, if Figure 1 and Figure 2 As shown, the adjustment component 6 includes:

[0042] Motor A3, the motor A3 is arranged on the support column 2, and is used to control the flipping of the photovoltaic glass 7;

[0043] A rotating rod 4, wherein the rotating rod 4 is rotatably connected to the supporting column 2 and is fixedly connected to the output shaft of the motor A3;

[0044] A motor B14, the motor B14 is disposed on the rotating rod 4 and is used to drive the photovoltaic glass 7 to move;

[0045] Suction cup A15, the suction cup A15 is fixedly connected to the output shaft of the motor B14, and is used for sucking the photovoltaic glass 7.

[0046] The foreign matter cleaning device of the utility model absorbs the photovoltaic glass 7 transported by the transport component through the suction cup A15, completes the reception of the photovoltaic glass 7 transported by the transport component, and drives the rotating rod 4 to rotate through the motor A3, so that the photovoltaic glass 7 can be flipped to a vertical position, so that foreign matters on the surface of the photovoltaic glass 7 can fall off due to the action of gravity, and then drives the glass 7 to move through the motor B14, so that the foreign matters on its surface can further fall off.

[0047] Preferably, the motor B14 is a vibration motor. After the motor A3 drives the photovoltaic glass 7 to flip to a vertical position, the motor B14 drives the photovoltaic glass 7 to shake, so that foreign matter on the photovoltaic glass 7 further falls off, further improving the foreign matter shedding capability of the device.

[0048] In another embodiment of the present application, the motor B14 is a rotating motor. After the motor A3 drives the photovoltaic glass 7 to flip to a vertical position, the motor B14 drives the photovoltaic glass 7 to rotate, so that foreign matter on the photovoltaic glass 7 is further removed, further improving the foreign matter removal capability of the device.

[0049] In the above, it should be understood that when the motor B14 drives the photovoltaic glass 7 to rotate, it can drive the photovoltaic glass 7 to rotate continuously along a certain rotation direction, and use centrifugal force to throw out foreign objects on the surface of the photovoltaic glass 7. It can also drive the photovoltaic glass 7 to rotate reciprocatingly, and use the inertia of repeated rotation to make foreign objects on the surface of the photovoltaic glass 7 fall off, thereby further improving the foreign object removal ability of the device.

[0050] In the present utility model, if Figure 1 and Figure 2 As shown, the transport assembly includes:

[0051] A fixing plate 11, wherein the fixing plate 11 is fixedly connected to the supporting column 2;

[0052] A motor C10, wherein the motor C10 is disposed on the fixing plate 11;

[0053] A transport rod 9, wherein the transport rod 9 is fixedly connected to an output shaft of the motor C10;

[0054] A suction cup B8 is fixedly connected to the bottom of the carrying rod 9 and is used to suck the photovoltaic glass 7 .

[0055] The foreign matter cleaning device of the utility model sucks up the photovoltaic glass 7 from the glass storage place through the suction cup B8, and then drives the conveying rod 9 to rotate through the motor C10, so that the photovoltaic glass 7 moves to the top of the suction cup A15, and sucks the bottom of the photovoltaic glass 7 through the suction cup A15, thereby completing the conveying and transferring process of the photovoltaic glass 7.

[0056] In the present utility model, if Figure 2 As shown, a grounding wire 5 is provided on the suction cup A15 for eliminating static electricity on the photovoltaic glass 7 as a whole.

[0057] The foreign matter cleaning device of the utility model can remove static electricity anomalies on the entire surface of the photovoltaic glass 7 by connecting the grounding wire 5 to the suction cup A15, thereby preventing foreign matter from being continuously adsorbed on the surface of the photovoltaic glass 7 due to static electricity, and further improving the foreign matter cleaning capability of the device.

[0058] In the present utility model, if Figure 1 and Figure 2 As shown, an opening is provided in the middle of the frame 1 to provide space for the movement of the photovoltaic glass 7. By providing an opening in the middle of the frame 1, the adjustment component 6 can avoid limiting the photovoltaic glass 7 by the frame 1 when driving the glass to flip, vibrate or rotate, so that the device can reasonably clean photovoltaic glass 7 of a larger size range, and can provide the photovoltaic glass 7 with a larger range of rotation and flipping angles, and provide a larger vibration range, thereby further improving the applicability of the device.

[0059] In one embodiment of the present application, it also includes:

[0060] A support frame 12, wherein the support frame 12 is fixedly connected to the bottom of the frame 1;

[0061] The fan 13 is rotatably connected to the support frame 12 and is used to blow away foreign matter on the surface of the photovoltaic glass 7.

[0062] In this embodiment, a support frame 12 is fixedly connected under the frame 1 to provide stable support for the fan 13. The fan 13 is arranged on the support frame 12 so that when the adjustment component 6 flips the photovoltaic glass 7 to a vertical position, foreign matter on the surface of the photovoltaic glass 7 can be blown away. The coordination of gravity and wind force can further enhance the foreign matter removal capability of the device.

[0063] In this embodiment, the support frame 12 and the adjustment component 6 are arranged relative to each other below the frame 1, and are used to make the wind blown by the fan 13 parallel to the surface of the photovoltaic glass 7. By making the direction of the wind blown by the fan 13 parallel to the surface of the photovoltaic glass 7, the fan 13 can effectively and directly blow foreign matter on the entire surface of the photovoltaic glass 7 out of the photovoltaic glass 7, thereby avoiding the situation where the wind direction of the fan 13 is not parallel to the photovoltaic glass 7, and the photovoltaic glass 7 blocks the wind blown by the fan 13, resulting in the inability to blow away foreign matter on the entire surface of the photovoltaic glass 7, or the wind direction of the fan 13 forms an angle with the surface of the photovoltaic glass 7, so that foreign matter on the surface of the photovoltaic glass 7 is always attached to the surface of the photovoltaic glass 7 under the action of wind force, affecting the blowing effect of the fan 13.

[0064] Preferably, the support columns 2 are arranged on opposite sides of the bottom of the frame 1, and two support columns 2 are arranged at both ends of one side of the bottom of the frame 1, the support frame 12 is arranged between the two support columns 2, and three support columns 2 are arranged at intervals on the other side of the bottom, two of which are arranged at both ends of the bottom of this side, and one support column 2 is arranged in the middle of the bottom of this side, and the adjustment component 6 is arranged on the support column 2 located on the middle side of the bottom of the frame. Through this arrangement, the wind blown by the fan 13 can cover the surface of the photovoltaic glass 7 in a larger range, so that the fan 13 can more effectively blow away foreign matter on the surface of the photovoltaic glass 7.

[0065] In this embodiment, the fans 13 are provided in multiple groups, and the multiple groups of fans 13 are arranged at intervals on the support frame 12. By providing multiple groups of fans 13, the device can more evenly and comprehensively blow away foreign matter on the entire surface of the photovoltaic glass 7, thereby improving the foreign matter cleaning ability of the device.

[0066] In this embodiment, the support frame 12 is a "well"-shaped structure. By setting the support frame 12 as a "well"-shaped structure, it is possible to effectively provide stable support for the fan 13 and improve the stability of the device during operation.

[0067] The utility model provides a device for cleaning foreign matter on the surface of photovoltaic glass. The working principle is as follows: when it is necessary to clean foreign matter on the surface of photovoltaic glass 7, the motor C10 drives the carrying rod 9 and the suction cup B8 to move to the top of the glass storage place, and the upper surface of the photovoltaic glass 7 is sucked. Then, the motor C10 drives the photovoltaic glass 7 sucked by the suction cup B8 to move so that it is transferred to the top of the suction cup A15, and the suction cup A15 sucks the lower surface of the photovoltaic glass 7. Then, the motor A3 drives the rotating rod 4 to transmit the motion to the suction cup A15, so that the photovoltaic glass 7 is flipped to a vertical position, and then the motor B14 drives the photovoltaic glass 7 to rotate. Vibration, through the action of gravity and shaking, foreign matter on the surface of the photovoltaic glass 7 can be fallen off and cleaned, and the static electricity anomaly on the surface of the photovoltaic glass 7 is removed through the grounding wire 5, thereby enhancing the foreign matter cleaning ability of the device. At this time, the fan 13 can be controlled to rotate, and the foreign matter on the surface of the photovoltaic glass 7 can be blown away by the rotation of the fan 13. The static electricity of foreign matter on the front side of the photovoltaic glass 7 is completely eliminated, and at the same time, the front side of the photovoltaic glass is affected by gravity and wind, so that the foreign matter is cleaned. Because the back side of the photovoltaic glass 7 is on the surface of the photovoltaic module, the main purpose of the device to clean the foreign matter on the surface of the photovoltaic glass 7 is to prevent foreign matter from entering the inside of the photovoltaic module, so only the front side of the photovoltaic glass 7 needs to be cleaned.

[0068] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any appropriate manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention, and all belong to the protection scope of the present invention. These simple modifications all belong to the protection scope of the present invention.
