Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and particularly relates to a grading and conveying system for photovoltaic panels. Background Art

[0002] A photovoltaic panel (also known as a solar panel) is a device that directly converts solar energy into electrical energy. It mainly consists of multiple photovoltaic cells, glass, a backplane, a frame, and a junction box, etc. Photovoltaic panels play a core role in a solar power generation system, which can convert the radiant energy of sunlight into electrical energy, thereby realizing the utilization of solar energy. When photovoltaic panels are mass-produced, there may be differences in quality. In order to avoid excessive quality differences among photovoltaic panels in the same box, some photovoltaic panels need to be graded by performance first, and then picked out together, and then a batch of photovoltaic panels with similar performance are packaged together.

[0003] Chinese Patent CN219513120U discloses a grading and inserting system for photovoltaic panels. Through the cooperation of a grading and inserting machine and a carrying mechanism, the adjustment process of the grading and inserting machine for inserting pieces among different carrying mechanisms is reduced, the running path of the grading and inserting machine is unified, and the inserting efficiency is relatively high and it is convenient for maintenance. However, this system does not clearly show how to dock with a packaging line system, and manual handling is still required between the two, so not only the working efficiency is reduced, but also the risk of dropping the photovoltaic panels is increased.

[0004] Therefore, it is necessary to develop an automated conveyor line to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a grading and conveying system for photovoltaic panels, which can orderly convey the graded photovoltaic panels to a component packaging system in batches by using a pallet, and then send the empty pallet back for continuous grading.

[0006] The utility model realizes the above purpose through the following technical scheme: A grading and conveying system for photovoltaic panels includes a component transportation line and a pallet return line arranged along a first direction, several grading mechanisms arranged along a second direction, several feeding RGVs, and several waiting RGVs. The first direction is perpendicular to the second direction. The widths of the feeding RGV and the waiting RGV along the first direction are both a. There are several first empty spaces on the component transportation line, and several second empty spaces on the pallet return line. The widths of the first empty space and the second empty space along the first direction are not less than a. The outlet of the component transportation line is docked with the inlet of the pallet return line to the component packaging system.

[0007] Specifically, the component transportation line and the pallet return line are arranged side by side, and the positions of the first empty space and the second empty space are adjacent to each other one by one.

[0008] Further, there are three placement areas arranged along the second direction on the feeding RGV, and the center distance between adjacent placement areas is equal to the conveying center distance between the component transportation line and the iron pallet return line.

[0009] Further, both ends of the component transportation line are respectively connected to a component packaging system.

[0010] The beneficial effects of the technical solution of the present utility model are as follows:

[0011] The present utility model relies on the feeding RGV to send the integrated structure of the photovoltaic panel and the iron pallet from the grading mechanism to the component transportation line. The waiting RGV fills the gaps between the component transportation line and the iron pallet return line. After the iron pallet sends out the photovoltaic panel, it returns, realizing the grading of the photovoltaic panel and the recycling of the iron pallet. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further elaborates the present utility model in detail in conjunction with specific embodiments.

[0021] Embodiment:

[0022] As Figure 1As shown, a photovoltaic panel grading conveying system of the utility model comprises a component transport line 1 and an iron pallet return line 2 arranged along a first direction, a plurality of grading mechanisms 3 arranged along a second direction, a plurality of feeding RGVs 4 and a plurality of waiting RGVs 5, the first direction is perpendicular to the second direction, the widths of the feeding RGV 4 and the waiting RGV 5 along the first direction are both a, a plurality of first idle areas 11 are arranged on the component transport line 1, a plurality of second idle areas 21 are arranged on the iron pallet return line 2, the widths of the first idle areas 11 and the second idle areas 12 along the first direction are not less than a, and the outlet of the component transport line 1 and the inlet of the iron pallet return line 2 are connected to the component packaging system.

[0023] The feeding RGV 4 is used to place the iron pallet. When the RGV4 approaches the grading mechanism 3, the components that have been stacked on the iron pallet according to the performance of multiple photovoltaic panels with similar performance and formed into a group in the grading mechanism 3 are moved out to the RGV4; then the feeding RGV 4 moves to a certain first gap area 11, so that the iron pallet stacked with photovoltaic panels is placed together on the component transportation line 1, and the other first gap areas of the component transportation line 1 downstream of the first gap area will be filled by the waiting RGV 4, so that the iron pallet stacked with photovoltaic panels can pass through the entire component transportation line 1 and then be sent to the component packaging system; the iron pallet sends the photovoltaic panels to the packaging and then returns to the iron pallet return line 2; the iron pallet return line 2 then sends the iron pallet to a certain feeding RGV 4, and the second gap area 21 position along the way is filled by the waiting RGV 5; the empty iron pallet is sent to the side of the grading mechanism 3 by the feeding RGV 4 to receive the new photovoltaic panel, thus realizing the grading of the photovoltaic panel and the circulation of the iron pallet.

[0024] like Figure 1 As shown, the component transport line 1 and the iron pallet return line 2 are arranged side by side, and the first idle area 11 and the second idle area 21 are located adjacent to each other.

[0025] The component transport line 1 and the iron pallet return line 2 are arranged close to each other so that they are located on the same side of the second direction of all the grading mechanisms 3 instead of being completely surrounded by the two flow lines. On the one hand, other equipment can be arranged on the other side of the grading mechanism 3. On the other hand, the moving distance between the feeding RGV 4 feeding and recycling the iron pallet is reduced, the conveying cycle is reduced, and the feeding RGV 4 has more time to stay on one side of the grading mechanism 3, thereby making the working time more reasonable.

[0026] like Figure 2 As shown, the feeding RGV 4 is provided with three placement areas arranged along the second direction, namely the first placement area 41, the second placement area 42 and the third placement area 43, and the center distance between adjacent placement areas is equal to the conveying center distance between the component transport line 1 and the iron pallet return line 2.

[0027] The feeding RGV 4 can carry multiple iron pallets at one time. After the iron pallet carrying the photovoltaic panel on the first placement area 41 is sent out to the component transportation line 1, the first placement area 41 becomes vacant. The feeding RGV 4 moves forward by a center distance. At this time, the first placement area 41 can be aligned with the iron pallet return line 2, so as to receive the empty iron pallet. The second placement area 42 is aligned with the component transportation line 1, and at the same time, the second iron pallet carrying the photovoltaic panel is sent out. Similarly, when the second placement area 42 receives the empty iron pallet, the third placement area 43 sends out the third iron pallet carrying the photovoltaic panel. After the third placement area 43 receives the empty iron pallet again, the feeding RGV 4 needs to return, thus saving the time of multiple round trips.

[0028] As Figure 1 shown, both ends of the component transportation line 1 are respectively connected to a component packaging system.

[0029] In this way, the component transportation line 1 can transport the component packaging system to both sides respectively. If the waiting RGV 5 is not in place on the path to one side, then the iron pallet can be fed in the other direction. Since the probability that the waiting RGV 5 is not in place on both sides at the same time is lower than the probability that the waiting RGV 5 is not in place on one side, this can better overall arrange the entire system.

[0030] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
