[0045] Next, the present disclosure will be described in detail.

[0046] Edge trimming is needed in the production process of photovoltaic modules. In order to facilitate the treatment of waste generated during the edge trimming process, i.e. photovoltaic tailings, a waste bin is generally provided at the lower side of the photovoltaic edge trimming machine, and the photovoltaic tailings generated during edge trimming will fall into the waste bin, so that the collection of photovoltaic tailings is realized. However, in the related art, the waste bin is cleaned manually, which is low in efficiency.

[0047] Please refer to FIG. 1, the present disclosure provides a photovoltaic edge trimming system, which comprises a photovoltaic edge trimming machine and a photovoltaic tailings cleaning device. Wherein, the photovoltaic edge trimming machine has the same meaning as generally understood by those skilled in the art, and the photovoltaic edge trimming machine is configured to cut the edges of the photovoltaic module 01 from the photovoltaic module 01, and the photovoltaic tailings cleaning device is configured to clean the cut parts, i.e. photovoltaic tailings.

[0048] The photovoltaic module 01 is the same as the meaning commonly understood by those skilled in the art, which is a power generation device that generates current when exposed to sunlight, generally made entirely or mostly of semiconductor materials such as silicon, and can power the power grid, houses, vehicles, computers, etc. In order to better absorb light, the photovoltaic module 01 generally has a plate-like structure, and the photovoltaic edge cutting machine is configured to cut the photovoltaic module 01 along the circumferential profile of the plate-like structure. During the cutting process, the cutter of the photovoltaic edge cutting machine moves relative to the photovoltaic module 01 along the circumferential profile of the plate-like structure, and the orientation of the cutter edge is the same as the direction of the cutter moving relative to the photovoltaic module 01. For the plate-like photovoltaic module 01, the extension path of the circumferential profile is perpendicular to the thickness direction.

[0049] In some embodiments of the present disclosure, the photovoltaic module 01 is a photovoltaic assembly. Generally, the photovoltaic assembly includes stacked battery pieces, tempered glass, encapsulating film, and back plate. During the preparation of the photovoltaic assembly, the above structures are first formed into a composite layer through a lamination process, and then the composite layer is cut by the photovoltaic edge cutting machine to remove excess material, which is generally a rubber strip at the edge of the photovoltaic assembly.

[0050] The photovoltaic tailings cleaning device provided by the embodiments of the present disclosure includes a first collection bin 1 and a cleaning mechanism 3. The first collection bin 1 is formed with a first collection cavity, and the first collection cavity has a first collection opening. The first collection opening is configured to be arranged towards the photovoltaic edge cutting machine, and the first collection cavity collects photovoltaic tailings falling from the photovoltaic edge cutting machine through the first collection opening. At least a part of the cleaning mechanism 3 is arranged in the first collection bin 1 and can move along the inner wall of the first collection bin 1 and push the photovoltaic tailings to slide along the inner wall of the first collection bin 1 to a target position.

[0051] In the embodiments of the present disclosure, the first collection opening is the opening of the first collection cavity, and the photovoltaic tailings can fall into the first collection cavity through the first collection opening. In some embodiments of the present disclosure, the first collection bin 1 includes a first sub-collection bin 11 and a second sub-collection bin 12, and the first sub-collection cavity 111 of the first sub-collection bin 11 and the second sub-collection cavity 121 of the second sub-collection bin 12 together form the first collection cavity. Please refer to FIG. 2 and FIG. 4, the first sub-collection opening 1111 of the first sub-collection cavity 111 and the second sub-collection opening 1211 of the second sub-collection cavity 121 together form the first collection opening.

[0052] In the embodiments of the present disclosure, the first collecting cavity collects the photovoltaic tailings falling from the photovoltaic edge cutting machine. That is, after the photovoltaic edge cutting machine cuts a part of the photovoltaic module 01 from the photovoltaic module 01, the cut part, i.e., the photovoltaic tailings, falls under the action of gravity. The falling photovoltaic tailings fall into the first collecting cavity below through the first collecting port, so as to realize the collection of the photovoltaic tailings by the first collecting cavity. It can be understood that the first collecting port is arranged close to the edge of the photovoltaic module 01. In some embodiments of the present disclosure, the first collecting port can be upward. In this way, the falling photovoltaic tailings can fall into the first collecting cavity through the first collecting port.

[0053] In the embodiments of the present disclosure, the inner wall of the first collecting bin 1, i.e., the inner wall of the first collecting cavity, and the inner wall of the second collecting bin 4 in the following are the same.

[0054] In the embodiments of the present disclosure, the cleaning mechanism 3 moves along the inner wall of the first collecting bin 1, which can be any part of the inner wall of the first collecting bin 1. In some embodiments of the present disclosure, the cleaning mechanism 3 is movably connected with the first collecting bin 1, and the cleaning mechanism 3 can move along the lower side wall of the first collecting cavity and push the photovoltaic tailings to slide along the lower side wall of the first collecting bin 1 to the target position. More photovoltaic tailings are likely to accumulate on the lower side wall of the first collecting cavity, and the cleaning mechanism 3 moves along the lower side wall of the first collecting cavity so that the cleaning mechanism 3 can better clean the lower side wall of the first collecting cavity. Of course, in some embodiments of the present disclosure, the cleaning mechanism 3 can also move along other parts of the inner wall of the first collecting bin 1, so as to clean other parts of the inner wall of the first collecting bin 1.

[0055] In the embodiments of the present disclosure, please refer to FIG. 3, the cleaning mechanism 3 can move along the inner wall of the first collecting bin 1 under the driving of the driving mechanism 2. The driving mechanism 2 can have various forms of implementation, for example, it can be a hydraulic driving mechanism, a pneumatic driving mechanism or an electric driving mechanism, etc. In some embodiments of the present disclosure, the base of the driving mechanism 2 can be fixedly connected with the first collecting bin 1, so that the installation is more convenient.

[0056] The photovoltaic tailings cleaning device provided by the embodiments of the present disclosure can move the cleaning mechanism 3 along the inner wall of the first collecting bin 1, and the cleaning mechanism 3 can push the photovoltaic tailings to slide along the inner wall of the first collecting bin 1. The photovoltaic tailings in the first collecting cavity can be accumulated at the target position under the pushing, so as to facilitate the cleaning, which can reduce manual operation and has high efficiency.

[0057] It can be understood that, in the embodiments of the present disclosure, the photovoltaic tailings falling into the first collecting bin 1 will be supported on the inner wall of the first collecting bin 1, for example, supported on the lower side wall of the first collecting bin 1, or hung on the other side wall of the first collecting bin 1, and it needs to be explained that in this case the photovoltaic tailings are in direct contact with the inner wall of the first collecting bin 1. The cleaning mechanism 3 moves along the inner wall of the first collecting bin 1, and the photovoltaic tailings on the movement path of the cleaning mechanism 3 will be pushed by the cleaning mechanism 3, thereby sliding relative to the inner wall of the first collecting bin 1, accumulating at the target position, and facilitating cleaning.

[0058] In some embodiments of the present disclosure, the cleaning mechanism 3 and the first collecting bin 1 can be movably connected. For example, in some embodiments of the present disclosure, the cleaning mechanism 3 and the first collecting bin 1 are slidingly connected and can slide relative to the first collecting bin 1, thereby pushing the photovoltaic tailings to slide along the inner wall of the first collecting bin 1 to the target position. In this way, the cleaning range of the cleaning mechanism 3 is larger. In some embodiments of the present disclosure, the cleaning mechanism 3 and the first collecting bin 1 can also be rotatably connected.

[0059] In some embodiments of the present disclosure, the cleaning mechanism 3 and the first collecting bin 1 can also be a split structure. For example, in some embodiments of the present disclosure, the cleaning mechanism 3 is a cleaning robot, the cleaning robot is arranged in the first collecting bin 1, and the cleaning robot and the first collecting bin 1 are a split structure. The cleaning mechanism can move along the inner wall of the first collecting bin 1 under a preset program, thereby pushing the photovoltaic tailings to slide along the inner wall of the first collecting bin 1 to the target position.

[0060] In some embodiments of the present disclosure, referring to FIG. 1, the movement of the cleaning mechanism 3 relative to the first collecting bin 1 has a component in the horizontal direction, for example, the movement of the cleaning mechanism 3 relative to the first collecting bin 1 is in the horizontal direction, which can push the photovoltaic tailings to slide along the inner wall of the first collecting bin 1 to one side of the photovoltaic edge trimming machine in the horizontal direction. In this structure, the target position and the photovoltaic edge trimming machine are arranged in the horizontal direction, that is, the target position is located on one side of the photovoltaic edge trimming machine in the horizontal direction, and the movement of the cleaning mechanism 3 relative to the first collecting bin 1 has a component in the horizontal direction, that is, during the movement of the cleaning mechanism 3 pushing the photovoltaic tailings along the inner wall of the first collecting bin 1, the movement of the photovoltaic tailings has a component in the horizontal direction, and the photovoltaic tailings can move to one side of the photovoltaic edge trimming machine in the horizontal direction, that is, to the target position. After the photovoltaic tailings are cut off, they will generally fall directly below the photovoltaic edge trimming machine. After the photovoltaic tailings are pushed to one side of the photovoltaic edge trimming machine, they are not easily blocked by the photovoltaic edge trimming machine during cleaning, thereby facilitating cleaning work.

[0061] In some embodiments of the present disclosure, referring to FIG. 1, the first collection bin 1 extends along the circumferential contour of the placement portion of the photovoltaic edge trimming machine, the placement portion is configured to place the photovoltaic module 01, and the circumferential contour of the placement portion matches the circumferential contour of the photovoltaic module 01. The extension path of the first collection opening matches the extension path of the first collection bin 1, and the cleaning mechanism 3 can move relative to the first collection bin 1 along the extension direction of the first collection bin 1, so as to push the photovoltaic tailings along the extension direction of the first collection bin 1, facilitating the photovoltaic tailings to slide along the inner wall of the first collection bin 1 to the target position.

[0062] In the embodiments of the present disclosure, the circumferential contour of the photovoltaic module 01 matches the movement path of the cutter of the photovoltaic edge trimming machine relative to the photovoltaic module 01 during the edge trimming process, and the orientation of the cutting edge of the cutter is the same as the movement direction of the cutter relative to the photovoltaic module 01.

[0063] In the embodiments of the present disclosure, the extension path of the first collection opening matches the extension path of the first collection bin 1, that is, the first collection opening also extends along the circumferential contour of the photovoltaic module 01 like the first collection bin 1. It can be understood that in the embodiments of the present disclosure, the first collection bin 1 extends in the horizontal direction, and at least a part of the circumferential contour of the photovoltaic module 01 extends in the horizontal direction. In some embodiments of the present disclosure, the circumferential contour of the photovoltaic module 01 can be perpendicular to the vertical direction c. In the embodiments of the present disclosure, the extension path refers to the path passing in the extension direction.

[0064] It can be understood that in the embodiments of the present disclosure, the cleaning mechanism 3 pushes the photovoltaic tailings in the first collection bin 1 to the target position along the extension direction of the first collection bin 1. In the case that the target position and the photovoltaic edge trimming machine are arranged in the horizontal direction, the extension direction of the first collection bin 1 is the horizontal direction, facilitating the cleaning mechanism 3 to push the photovoltaic tailings to the target position along the extension direction of the first collection bin 1. On this basis, in some embodiments of the present disclosure, the cleaning mechanism 3 is in sliding connection with the first collection bin 1, and the relative sliding direction of the cleaning mechanism 3 and the first collection bin 1 is the extension direction of the first collection bin 1.

[0065] By extending the first collection bin 1 along the circumferential contour of the placement portion, the extension path of the first collection opening matches the extension path of the first collection bin 1, so that the first collection bin 1 can collect the photovoltaic tailings falling in a larger range in the horizontal direction. The direction in which the cleaning mechanism 3 moves relative to the first collection bin 1 is the extension direction of the first collection bin 1, which is conducive to reducing the volume of the cleaning mechanism 3, so that a smaller cleaning mechanism 3 can better clean the first collection bin 1, and the convenience of processing and manufacturing the cleaning mechanism 3 is improved.

[0066] On this basis, in some embodiments of the present disclosure, referring to FIG. 1, the inner wall of the first collecting cavity comprises a first guide surface, the extension direction of the first guide surface matches the extension path of the first collecting bin 1, the upper end of the first guide surface extends to the first collecting opening, and the first guide surface is inclined relative to the vertical direction c so that the upper end of the first guide surface is away from the middle part of the first collecting opening relative to the lower end. By arranging the first guide surface, it is beneficial for the photovoltaic tailings to slide along the first guide surface into the first collecting cavity more accurately, thereby facilitating the cleaning of the photovoltaic tailings.

[0067] In some embodiments of the present disclosure, referring to FIGS. 2-5, the first collecting bin 1 comprises a first sub-collecting bin 11 and a second sub-collecting bin 12, the first sub-collecting bin 11 and the second sub-collecting bin 12 both extend along the circumferential contour of the photovoltaic module 01, the first sub-collecting bin 11 and the second sub-collecting bin 12 have an included angle in the extension direction, one end of the first sub-collecting bin 11 extends to the target position, one end of the second sub-collecting bin 12 extends to the first sub-collecting bin 11 and communicates with the first sub-collecting bin. The cleaning mechanism 3 comprises a first sub-cleaning mechanism 31 corresponding to the first sub-collecting bin 11, the first sub-cleaning mechanism 31 can push the photovoltaic tailings to slide along the inner wall of the first sub-collecting bin 11 to the target position; the cleaning mechanism 3 comprises a second sub-cleaning mechanism 32 corresponding to the second sub-collecting bin 12, the second sub-cleaning mechanism 32 can push the photovoltaic tailings into the first sub-collecting bin 11.

[0068] In the embodiments of the present disclosure, the first sub-collecting bin 11 and the second sub-collecting bin 12 extend along two different parts of the circumferential contour of the placing part, the two parts have an included angle in the extension direction, correspondingly, the first sub-collecting bin 11 and the second sub-collecting bin 12 have an included angle in the extension direction. The first sub-collecting bin 11 has a first sub-collecting opening 1111 for the photovoltaic tailings to fall into, the second sub-collecting bin 12 has a second sub-collecting opening 1211 for the photovoltaic tailings to fall into, the extension path of the first sub-collecting opening 1111 is the same as the extension direction of the first sub-collecting bin 11, and the extension path matches, the extension direction of the second sub-collecting opening 1211 is the same as the extension direction of the second sub-collecting bin 12, and the extension path matches.

[0069] In the embodiments of the present disclosure, the first sub-collecting bin 11 extends to the target position, which means that the first sub-collecting bin 11 extends to the target position along its own extension direction, that is, the target position is located at one end of the first sub-collecting bin 11 in its own extension direction, and the second sub-collecting bin 12 extends to the first sub-collecting bin 11, which means that the second sub-collecting bin 12 extends to the first sub-collecting bin 11 along its own extension direction, and the first sub-collecting bin 11 is located at one end of the second sub-collecting bin 12 in its own extension direction.

[0070] In the embodiments of the present disclosure, the first sub-cleaning mechanism 31 pushes the photovoltaic tailings in the first sub-collection bin 11 along the extension direction of the first sub-collection bin 11 to slide along the inner wall of the first sub-collection bin 11 to the target position; the second sub-cleaning mechanism 32 pushes the photovoltaic tailings in the second sub-collection bin 12 along the extension direction of the second sub-collection bin 12 to slide along the inner wall of the second sub-collection bin 12 to the first sub-collection bin 11, and enter the first sub-collection bin 11.

In order to facilitate understanding, the cleaning process is described below. In the edge trimming process, part of the photovoltaic tailings falls into the first sub-collection bin 11 through the first sub-collection port 1111, and the other part of the photovoltaic tailings falls into the second sub-collection bin 12 through the second sub-collection port 1211. The second sub-cleaning mechanism 32 can first push the photovoltaic tailings in the second sub-collection bin 12 into the first sub-collection bin 11, and then push all the photovoltaic tailings in the first sub-collection bin 11 to the target position.

[0073] In some embodiments of the present disclosure, please refer to FIGS. 2-5, one end of the second sub-collection bin 12 close to the first sub-collection bin 11 can be located directly above the first sub-collection bin 11, which is beneficial to the photovoltaic tailings in the second sub-collection bin 12 to fall into the first sub-collection bin 11 through the first sub-collection port 1111 after being pushed by the second sub-cleaning mechanism 32 to one side of the second sub-collection bin 12 in the extension direction. In some embodiments of the present disclosure, the bottom wall of the second sub-collection cavity 121 includes a second guide surface 1212, the second guide surface 1212 extends to the first sub-collection bin 11 and is inclined relative to the horizontal direction, so that the end of the second guide surface 1212 close to the first sub-collection bin 11 is lower than the other end. In this way, after the second sub-cleaning mechanism 32 pushes the photovoltaic tailings in the second sub-collection bin 12 to the second guide surface 1212, the photovoltaic tailings will slide downward along the second guide surface 1212 to one side of the second sub-collection bin 12 in the extension direction, and then fall into the first sub-collection bin 11 through the first sub-collection port 1111.

In this way, the sweeping mechanism 3 extends out of the first collection cavity and is in transmission connection with the driving mechanism 2. The driving mechanism 2 can not occupy the space in the first collection bin 1, which is beneficial to improve the utilization rate of the first collection cavity and is also beneficial to the internal structure of the first collection cavity being relatively simple and not easy to accumulate a large amount of photovoltaic tailings that are difficult to clean.

[0082] The first direction in the embodiments of the present disclosure can extend along a straight line, or extend along a curve or a broken line, etc. It can be understood that the first direction is the extension direction of the inner wall of the first collecting bin 1. For example, the first direction is the extension direction of the lower side wall of the first collecting cavity. Please refer to FIGS. 6 and 7, the push plate 312 and the cleaning brush 313 can move along the lower side wall of the first collecting cavity, so as to facilitate the cleaning mechanism 3 to push the photovoltaic tailings along the lower side wall of the first collecting cavity to the target position by the push plate 312 and the cleaning brush 313.

[0083] In the embodiments of the present disclosure, the first direction is the movement direction of the cleaning mechanism 3 relative to the first collecting bin 1.

[0084] For example, in some embodiments of the present disclosure, please refer to FIGS. 2-5, the circumferential profile of the placement part is a rectangle, the first sub-collecting bin 11 extends along the long side of the rectangle, the first sub-cleaning mechanism 31 moves along the extension direction of the first sub-collecting bin 11 and pushes the photovoltaic tailings to slide along the inner wall of the first sub-collecting bin 11 to the target position. In this case, for the first sub-collecting bin 11 and the first sub-cleaning mechanism 31, the first direction refers to the length direction a of the rectangle. The first sub-cleaning mechanism 31 can extend out of the first sub-collecting cavity 111 through the first sub-collecting port 1111 and extend to the side of the first sub-collecting port 1111 in the width direction b of the rectangle, and the first sub-cleaning mechanism 31 is connected with the first sub-driving mechanism.

[0086] In some embodiments of the present disclosure, referring to FIGS. 2-5, the first collecting bin 1 extends to opposite ends of the photovoltaic edge trimming machine, and the cleaning mechanism 3 is capable of reciprocating along the extension direction of the first collecting bin 1 and pushing the photovoltaic tailings to the opposite ends of the photovoltaic edge trimming machine in the extension direction of the first collecting bin 1. The two ends of the first collecting bin 1 extend to the opposite ends of the photovoltaic edge trimming machine, and the opposite ends of the photovoltaic edge trimming machine refer to the opposite ends of the photovoltaic edge trimming machine in the extension direction of the first collecting bin 1. During the reciprocation of the cleaning mechanism 3 along the extension direction of the first collecting bin 1, the first collecting bin 1 can be repeatedly cleaned, and the cleaning efficiency can be improved by cleaning the first collecting bin 1 twice in one reciprocation. On this basis, in some embodiments of the present disclosure, the first sub-cleaning mechanism 31 can reciprocate along the extension direction of the first sub-collecting bin 11 and push the photovoltaic tailings to the opposite ends of the photovoltaic edge trimming machine in the extension direction of the first sub-collecting bin 11.

The second collecting port 411 is correspondingly arranged with the discharge port 1112, and the second collecting bin 4 can collect the photovoltaic tailings discharged from the discharge port 1112. Since the photovoltaic tailings in the first collecting bin 1 are discharged through the discharge port 1112 and enter the second collecting bin 4 through the second collecting port 411, the photovoltaic tailings can be cleaned by cleaning the second collecting bin 4 or replacing the second collecting bin 4, which is more efficient.

In this way, through the adjusting piece 316, the cleaning brush 313 can adjust the pressure between the cleaning brush 313 and the inner wall of the first collecting bin 1, which is beneficial to improve the smoothness of the cleaning mechanism 3 in the process of sliding relative to the inner wall while ensuring that the cleaning brush 313 has a certain cleaning effect.

[0094] In the embodiments of the present disclosure, along the first direction, the cleaning brush 313 and the push plate 312 can sequentially clean the same part of the inner wall of the first collecting bin 1, which is beneficial to improve the cleaning effect.

In some embodiments of the present disclosure, referring to FIGS. 6, 7 and 8, the push plate 312 abuts against the inner wall of the first collecting bin 1 along the extension direction of the push plate 312. During the movement of the push plate 312 relative to the first collecting bin 1, the end wall at one end of the push plate 312 along the extension direction of the push plate 312 slides relative to the inner wall of the first collecting bin 1.

In some embodiments of the present disclosure, the at least two rollers 315 can be arranged in the first direction.

[0112] In some embodiments of the present disclosure, referring to FIGS. 6, 7 and 8, along the axial direction of the roller 315, the roller 315 is arranged at one end of the base 311, and the end of the base 311 away from the roller 315 is slidably connected to the first collecting bin 1 through the sliding block 318 and the sliding rail, and the sliding block 318 and the sliding rail support each other in the vertical direction c. In this way, the sliding block 318 and the sliding rail mechanism and the roller 315 support the two ends of the base 311 respectively, the structure is relatively simple, the cost is low, the base 311 is not easy to incline, and the cleaning mechanism 3 can be stably installed on the base 311.

[0113] In some embodiments of the present disclosure, referring to FIGS. 6, 7 and 8, the cleaning mechanism 3 can also not include the cleaning brush 313, but include the push plate 312. In this way, the structure is simplified. For example, in some embodiments of the present disclosure, the photovoltaic module 01 is in a rectangular plate structure, the first sub-collection bin 11 extends along the long side of the rectangle, the second sub-collection bin 12 extends along the short side of the rectangle, the first sub-cleaning mechanism 31 includes the cleaning brush 313, and the second sub-cleaning mechanism 32 does not include the cleaning brush 313.

[0114] In some embodiments of the present disclosure, referring to FIGS. 6, 7 and 8, the first end of the cleaning mechanism 3 extends out of the first collection cavity through the first collection port and extends to one side of the first collection port in the second direction. The first end of the cleaning mechanism 3 is slidingly connected with the outer wall of the first collection bin 1 along the first direction. The cleaning mechanism 3 can move along the inner wall of the first collection bin 1 and push the photovoltaic tailings to slide along the inner wall of the first collection bin 1 to the target position. The second direction is perpendicular to the first direction and perpendicular to the vertical direction. For example, the sliding connection is achieved through the sliding rail and the sliding block 318. The extension of the cleaning mechanism 3 out of the first collection cavity and the sliding connection with the first collection bin 1 can not occupy the space inside the first collection bin 1, which is conducive to improving the utilization rate of the first collection cavity and simplifying the internal structure of the first collection cavity, so that the photovoltaic tailings are not easily accumulated.

[0115] In some embodiments of the present disclosure, referring to FIGS. 2-5, the photovoltaic tailings cleaning device further includes a guide plate 6. The guide plate 6 is arranged on the upper side of the first collection cavity and correspondingly arranged at the lower end of the first collection port. The guide plate 6 is inclined relative to the vertical direction c, so that the upper end of the guide plate 6 is away from the middle part of the first collection port relative to the lower end. The first end of the cleaning mechanism 3 passes through the interval between the guide plate 6 and the first collection port in the vertical direction and extends to one side of the first collection port in the second direction. By arranging the guide plate 6, the photovoltaic tailings can be more accurately dropped into the first collection cavity, and the photovoltaic tailings can be cleaned. In some embodiments of the present disclosure, the guide plate 6 can be arranged on the opposite sides of the first collection port relative to the first guide surface. In this way, the photovoltaic tailings can be more accurately dropped into the first collection cavity, and the photovoltaic tailings can be cleaned.

[0116] In some embodiments of the present disclosure, the guide plate 6 extends along the first direction. In this way, the guide plate 6 can guide the photovoltaic tailings falling from a larger range to be more accurately dropped into the first collection cavity, and the photovoltaic tailings can be cleaned.
