When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0031] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0032] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] The present invention provides a paving device, please refer to Figure 1, used for paving photovoltaic panels, the paving equipment includes a handling device 10 and a material frame device 20, the material frame device 20 is used to load photovoltaic panels, and the handling device 10 grabs the photovoltaic panels in the material frame device 20.

[0034] In one implementation, please refer to Figures 2 to 5 The material frame device 20 includes a fixed member 21, a first movable member 22, a second movable member 23 and a third movable member 24; wherein the first movable member 22 and the fixed member 21 are arranged relatively spaced apart in a first direction X, and the first movable member 22 moves toward or away from the fixed member 21; the second movable member 23 and the third movable member 24 are arranged relatively spaced apart in a second direction Y, and the second movable member 23 moves toward or away from the third movable member 24; the first direction X and the second direction Y are perpendicular, and the photovoltaic panel is placed between the fixed member 21, the first movable member 22, the second movable member 23 and the third movable member 24.

[0035] Specifically, the appearance of the material frame device 20 can be a hexahedral structure, wherein the fixed member 21, the first movable member 22, the second movable member 23 and the third movable member 24 constitute the four sides of the material frame device 20. It can be understood that the photovoltaic panel is a quadrilateral panel, so the fixed member 21, the first movable member 22, the second movable member 23 and the third movable member 24 correspond to the four sides of the photovoltaic panel respectively, and the centering and flushing of the photovoltaic panel is achieved by the movement of the first movable member 22, the second movable member 23 and the third movable member 24.

[0036] Furthermore, the fixing member 21, the first moving member 22, the second moving member 23 and the third moving member 24 define a receiving space 20A of the material frame device 20. The top of the material frame device 20 is an opening, and the photovoltaic panel is placed in the receiving space 20A or taken out from the receiving space 20A through the opening. The photovoltaic panels are stacked in the receiving space 20A, and multiple photovoltaic panels are stacked in a direction perpendicular to the ground.

[0037] In a specific embodiment, the photovoltaic panel has a first side, a second side, a third side and a fourth side, the first side and the third side are opposite to each other, and the second side and the fourth side are opposite to each other; wherein the fixing member 21 may correspond to the first side of the photovoltaic panel, the first moving member 22 may correspond to the third side of the photovoltaic panel, the second moving member 23 may correspond to the second side of the photovoltaic panel, and the third moving member 24 may correspond to the fourth side of the photovoltaic panel. The stacking direction of the multiple photovoltaic panels is the third direction Z (i.e., the height direction).

[0038] When the photovoltaic panel is placed in the material frame device 20, the first moving member 22 can move toward the fixed member 21 to push the stacked photovoltaic panels to move toward the fixed member 21, and the second moving member 23 can move toward the third moving member 24 to push the stacked photovoltaic panels to move toward the third moving member 24. Alternatively, the second moving member 23 and the third moving member 24 can move toward each other at the same time to push the stacked photovoltaic panels to align.

[0039] In one implementation, please refer to Figures 2 to 5 , the material frame device 20 includes a loading state, a centering state and a transporting state, wherein, in the process of switching to the loading state, the first moving member 22 moves away from the fixed member 21, and the second moving member 23 and the third moving member 24 move away from each other, so that the opening of the material frame device 20 is expanded, and the photovoltaic panel can enter the material frame. In the process of switching to the centering state, the first moving member 22 moves toward the fixed member 21, and the second moving member 23 and the third moving member 24 move toward each other, so that the photovoltaic panel is centered and aligned. In the process of switching to the transporting state, the first moving member 22 moves away from the fixed member 21, and the second moving member 23 and the third moving member 24 move away from each other, so that the opening of the material frame device 20 is expanded, and the photovoltaic panel can be taken out of the material frame.

[0040] It can be understood that, in the centering state, due to the tightening of the first to third moving members 22, 24, the opening of the material frame device 20 is the smallest, and the opening size of the material frame device 20 is approximately equal to the area size of the photovoltaic panel; in the loading state and the transport state, due to the loosening of the first to third moving members 22, 24, the opening of the material frame device 20 is the largest, and the opening size of the material frame device 20 is much larger than the area size of the photovoltaic panel.

[0041] Optionally, in a specific embodiment, the centering process of the photovoltaic panel includes: the first moving member 22 moves before the second moving member 23 and the third moving member 24, so that the photovoltaic panel is aligned in the first direction X; then, the second moving member 23 (and / or the third moving member 24) moves, so that the photovoltaic panel is aligned in the second direction Y.

[0042] Optionally, in a specific embodiment, the centering process of the photovoltaic panel includes: the first movable member 22, the second movable member 23 and the third movable member 24 move simultaneously, and the first movable member 22 moves toward the fixed member 21, and the second movable member 23 and the third movable member 24 move toward each other, so that the photovoltaic panel is aligned in the first direction X and the second direction Y at the same time.

[0043] The present invention provides a material frame device 20, which includes a fixed part 21, a first movable part 22, a second movable part 23 and a third movable part 24. The first movable part 22 moves toward the fixed part 21, and the second movable part 23 moves toward the third movable part 24, so that the centering operation of the photovoltaic panel can be achieved. After the centering is completed, the first movable part 22 is driven away from the fixed part 21, and the second movable part 23 is driven away from the third movable part 24, so that the photovoltaic panel is loosened, and the handling device 10 can carry the photovoltaic panel in the material frame device 20, so as to avoid the photovoltaic panel from being skewed and collapsed, and can improve the accuracy of the handling device 10 in grabbing the photovoltaic panel, and reduce the error of the photovoltaic panel installation device.

In the loading state, the distance from the first moving member 22 to the fixed member 21 is A2, and the distance from the second moving member 23 to the third moving member 24 is B2. In order to ensure that the photovoltaic panel can be placed in the feed frame, it is necessary to satisfy A2>A1, B2>B1.

[0081] Then in the process of switching to the centering state, the controller controls the first moving member 22 to move a, controls the second moving member 23 to move a distance b1, controls the third moving member 24 to move b2, and has a sensor to detect the moving distances of the three moving members in real time and feed back to the controller. When it meets: A1+a=A2, B1+b1+b2=B2, this realizes the centering of the photovoltaic panel, and the controller can control the three moving members to stop. On the contrary, in the process of switching from the centering state to the carrying state, it is necessary to detect the distances of the three moving members moving a, b1 and b2 respectively.

[0082] Optionally, in a specific embodiment, the second moving member 23 may be controlled to move a distance b1 equal to the third moving member 24. Alternatively, the third moving member 24 may be controlled to move a distance b2 less than the second moving member 23.

[0083] In one implementation, please refer to Figures 2 to 4 The base 25 further includes a second bottom plate 252, the first bottom plate 251 is disposed above the second bottom plate 252, the photovoltaic panel is stacked on the first bottom plate 251, and the first bottom plate 251 can be raised and lowered relative to the second bottom plate 252. The first telescopic portion 223 to the third telescopic portion 242 in the above embodiment are all connected to the second bottom plate 252.

[0084] In one implementation, please refer to Figure 1The paving equipment also includes a chassis device 30, the material frame device 20 is rotatably connected to the chassis device 30, and the material frame device 20 rotates relative to the chassis device 30 so that the fixing member 21 is close to the chassis device 30.

[0085] Specifically, the chassis device 30 is used to provide mobility for the paving equipment. The material frame device 20 and the transport device 10 are both arranged on the chassis device 30. The chassis device 30 can be a track or a wheel. The chassis device 30 drives the material frame device 20 and the transport device 10 to move to the target position for installing the photovoltaic panels.

[0086] Optionally, the chassis device 30 and the material frame device 20 are connected by a rotating assembly, and the rotating assembly can be understood as the second bottom plate 252 of the material frame device 20 mentioned above. The rotating assembly drives the material frame device 20 to rotate relative to the chassis device 30, and the rotation angle can be any degree from 0° to 90°. It can be understood that in the loading state, the rotating assembly drives the material frame device 20 to rotate so that the opening direction of the material frame device 20 is perpendicular to the first direction X; then after the loading is completed, the rotating assembly drives the material frame device 20 to rotate so that the opening direction of the material frame device 20 is perpendicular to the height direction, and then switches to the centering state.

[0087] Optionally, the rotating assembly drives the material frame device 20 to rotate so that the fixing member 21 approaches and connects to the chassis device 30. That is, in a specific embodiment, the chassis device 30 rotates toward one side of the fixing member 21 so that the fixing member 21 is located between the first moving member 22 and the chassis device 30.

[0088] In one embodiment, the present invention further provides a control method for the material frame device 20, please refer to Figure 6 , including the following steps:

[0089] In step S10 , the photovoltaic panel is placed in the material frame device 20 .

[0090] In step S20 , the first moving member 22 moves toward the fixing member 21 and pushes the photovoltaic panel to move toward the fixing member 21 .

[0091] In step S30 , the second moving member 23 moves toward the third moving member 24 , and pushes the photovoltaic panel to move toward the third moving member 24 .

[0092] The first moving member 22 and the fixed member 21 are relatively spaced apart in the first direction X, the second moving member 23 and the third moving member 24 are relatively spaced apart in the second direction Y, and the first direction X and the second direction Y are perpendicular.

[0093] Specifically, in step S10, the material frame device 20 is first switched to the loading state, that is, the first moving member 22, the second moving member 23 and the third moving member 24 are all at the far end, and the opening of the material frame is large, so that the photovoltaic panel can be placed in the material frame device 20. At this time, the distance from the first moving member 22 to the fixed member 21 is A2, and the distance from the second moving member 23 to the third moving member 24 is B2.

[0094] Optionally, in step S20, the material frame device 20 switches from the loading state to the centering state, the first movable member 22 moves toward the fixed member 21, and the moving distance a of the first movable member 22 is a=A2-A1, and A1 is the width of the photovoltaic panel.

[0095] Optionally, in step S30, the material frame device 20 is in a loading state and switched to a centering state, the second moving member 23 moves toward the third moving member 24, and the third moving member 24 also moves toward the second moving member 23, and the moving distance b1 of the second moving member 23 and the moving distance b2 of the third moving member 24 satisfy that b1+b2=B2-B1, where B1 is the length of the photovoltaic panel.

[0096] It should be explained that the above steps S20 and S30 can be completed simultaneously or successively, and it is not limited to that step S20 must be completed before step S30.

[0097] In one embodiment, the centering of the photovoltaic panel by the material frame device 20 is based on the position of the first bottom plate 251 and the handling device 10. In step S20, the first movable member 22 moves toward the fixed member 21, including: the detector detects the first relative position of the photovoltaic panel and the first bottom plate 251, and detects the second relative position of the handling assembly and the photovoltaic panel, and the controller controls the first movable member 22 to move toward the fixed member 21 according to the first relative position and the second relative position.

[0098] In one embodiment, in step S30 , the second moving member 23 moves toward the third moving member 24 : the controller controls the second moving member 23 to move toward the third moving member 24 through the first relative position and the second relative position, and the third moving member 24 also moves toward the second moving member 23 .

[0099] Specifically, the detector mentioned above can be a camera, a radar or an infrared sensor. The first relative position is the relative offset between the photovoltaic panel and the first base plate 251. It can be understood that after loading, due to the large opening of the material frame, the photovoltaic panel may not be located in the middle of the first base plate 251, and may be offset to the left (right) or forward (backward), or the photovoltaic panel may be partially rotated. The detector detects the specific offset before centering and transmits the detected offset data to the controller. The controller controls the specific distance (a, b1 and b2) of the movement of the three moving parts according to the offset, and the actual displacement is detected by the sensor in the above embodiment.

[0100] Furthermore, the detector also needs to detect the second relative position of the transport assembly and the photovoltaic panel, and detect the offset of the photovoltaic panel relative to the transport device 10, and transmit the detected offset data to the controller. The controller combines the offset of the first relative position and the offset of the second relative position to determine the specific distances (a, b1 and b2) moved by the three moving parts, and controls the three moving parts to move the corresponding distances.

[0101] In one implementation, after step S30, the method further includes:

[0102] In step S40 , the first moving member 22 is moved toward the fixed member 21 , the second moving member 23 is moved toward the third moving member 24 , and the third moving member 24 is moved away from the second moving member 23 .

[0103] Specifically, in this step, the material frame device 20 is switched from the centering state to the transporting state. The moving distance of the moving part can be determined by the controller according to the moving distance previously recorded by the sensor. It can be understood that in the transporting state, until the photovoltaic panels in the material frame device 20 are completely grabbed, the material frame device 20 rotates driven by the rotating assembly to continue loading, so the loading state and the transporting state can be the same working state.

[0104] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
