Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic cell production, and particularly relates to a photovoltaic cell piece material box automatic recovery and conveying line. BACKGROUND

[0002] In the photovoltaic cell manufacturing process, cell piece dicing is one of the key steps. Since the cell piece may have uneven coating in a large area, in order to avoid affecting the power of the cell, the cell piece is cut and processed through the dicing action, and then divided into smaller and more uniform cell pieces, so as to improve the stability and reliability of the whole cell.

[0003] As disclosed in Chinese patent application No. 202320934065.8, a battery box conveying device and a cell piece dicing machine are provided. The battery box conveying device comprises a first conveying mechanism, a transfer mechanism, a second conveying mechanism, a lifting mechanism and an empty box conveying mechanism. The transfer mechanism is used to receive the full material battery box conveyed by the first conveying mechanism, drive the full material battery box to lift and convey the full material battery box to the second conveying mechanism. The lifting mechanism is used to receive the empty battery box conveyed by the second conveying mechanism and drive the empty battery box to descend to the feeding end of the empty box conveying mechanism.

[0004] In the above-mentioned document, the transfer mechanism respectively connects the first conveying mechanism and the second conveying mechanism at different height positions, so that the full material battery box is conveyed from the upper layer of the double-layer AGV trolley to the first conveying mechanism, and then to the second conveying mechanism. The empty battery box with full material is lifted from the second conveying mechanism to the empty box conveying mechanism by the lifting mechanism, so that the empty battery box is conveyed to the lower layer of the double-layer AGV trolley, thereby realizing the recovery of the empty battery box. In this process, the empty battery box needs to be moved to the empty box conveying mechanism at different heights by the lifting mechanism to realize recovery. At the same time, since the conveying stage and the recovery stage of the battery box are at different heights, the recovery time of the empty battery box is lengthened, thereby reducing the recovery efficiency. Moreover, only the empty box conveying mechanism is used for sequential conveying, which cannot realize the recovery of the material box immediately after the conveying of the material box is completed, thereby improving the production efficiency. SUMMARY

[0005] The present application aims to provide a photovoltaic cell piece material box automatic recovery and conveying line, which can improve the recovery efficiency of the cell piece material box, shorten the waiting time of the cell piece material box recovery and improve the production efficiency.

[0006] To achieve the above objectives, the present invention provides an automatic recycling and conveying line for photovoltaic cell boxes, including a recycling conveying mechanism, a transfer mechanism, and two or more feeding conveying mechanisms. The recycling conveying mechanism includes a support, a first conveying device, and two or more second conveying devices. Two or more second driving devices are provided on the support. The first conveying device, which is perpendicular to the support, is located on one side of the support. The second driving device is connected to the second conveying device located at the top of the support and slidably connected to the support. The feeding conveying mechanism is located on both sides of the first conveying device and is arranged side by side with the first conveying device. Two or more buffer components are provided between the second driving devices. The transfer mechanism is located above the feeding conveying mechanism. After the feeding conveying mechanism moves the cell box to below the transfer mechanism, the transfer mechanism grabs the cells in the cell box and transfers them to the next process. After the cells are grabbed, the cell box is conveyed from the feeding conveying mechanism to the second conveying device. Then, the second driving device drives the second conveying devices at both ends of the support to slide alternately on the support to the first conveying device, so that the cell box is conveyed from the middle of the two feeding conveying mechanisms to the first conveying device through the second conveying device to achieve recycling.

[0007] The above configuration allows the feeding conveyors on both sides of the first conveying device to simultaneously feed the battery cell boxes to the transfer mechanism. After the transfer mechanism has picked up all the battery cells from the battery cell boxes, it can further transport the empty battery cell boxes longitudinally to the second conveying device aligned with the feeding conveyor. Then, the second drive device drives the second conveying devices at both ends of the support to move laterally to the first conveying device. This allows the empty battery cell boxes on the second conveying device to be transported to the first conveying device for recycling. In this way, within the same conveying surface at the same height, the battery cell boxes are first transported longitudinally, then laterally, and then recycled by reverse longitudinal transport. This allows the empty battery cell boxes in the feeding conveyors on both sides of the recycling conveying mechanism to be recycled through alternating transport, thereby improving the recycling efficiency of the battery cell boxes and effectively shortening the waiting time for recycling. After the battery cells in the battery cell boxes have been transferred, it is only necessary to move the second conveying device to alternately transport them to the first conveying device, thereby achieving efficient recycling of the empty battery cell boxes and improving production efficiency.

[0008] Furthermore, the conveying surfaces of the feeding conveying mechanism, the first conveying device, and the second conveying device are all within the same height plane.

The other end of the third rack is provided with the third transmission wheel, and the third transmission wheel is connected through the third transmission belt.

The automatic recycling and conveying line for photovoltaic cell material boxes according to claim 8, characterized in that: The transfer mechanism includes a fixed frame, a lateral moving component, a longitudinal moving component, and a suction cup. The bottom of the fixed frame is located between the first conveying device and the feeding conveying mechanism. The lateral moving component is located on the top of the fixed frame. The longitudinal moving component is connected to the lateral moving component. The suction cup is connected to the longitudinal moving component. After the suction cup adsorbs the battery cells on the material box, it drives the battery cells to move up and down through the longitudinal moving component. The lateral moving component drives the longitudinal moving component to move laterally, transferring the battery cells from the material box located in the feeding conveying mechanism to the next process.

10. An automatic recycling and conveying line for photovoltaic cell material boxes according to claim 8, characterized in that: The conveying width of the feeding conveyor is set to correspond to the conveying width of the first conveying device and the conveying width of the second conveying device.
