Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic equipment, and particularly relates to a junction box preparation and feeding device. Background Art

[0002] When a solar photovoltaic panel is produced, after the silicon wafer arrays are arranged on a glass plate, multiple arranged silicon wafers need to be connected by busbars. Subsequently, a junction box needs to be fixed on the photovoltaic panel. At the same time, the lead end of the busbar needs to be reliably connected to the junction box to achieve electrical connection with a control device and the like.

[0003] For large-sized photovoltaic panels, the junction box structures for connecting busbars on the same solar panel are different. The junction box in the middle part is a wireless junction box, while the junction boxes at both ends are wired junction boxes.

[0004] In the patent document with the application publication number CN115173176A, a junction box automatic installation machine is disclosed, which includes a conveying part and an operating part. Specifically: the conveying path of the conveying part is provided with a positioning station, a lead shaping station, a junction box installation station, and a welding station. The conveying part steps to convey the battery string assembly, and each time it steps, it conveys a junction box installation position from the current operating station to the next operating station; the operating part includes a positioning mechanism, a lead shaping mechanism, a junction box installation mechanism, and a welding mechanism. Specifically: the positioning mechanism is located above the positioning station and is used for positioning the junction box installation position; the lead shaping mechanism is located above the lead shaping station and is used for tearing off the adhesive tape on the junction box installation position and shaping the leads; the junction box installation mechanism is located above the junction box installation station and is used for installing the junction box on the junction box installation position; the welding mechanism is located above the welding station and is used for performing welding on the junction box installation position. This realizes the automatic installation of the junction box and improves the installation efficiency of the junction box.

[0005] However, this solution is set for the structure where the first junction box installation position, the second junction box installation position, and the third junction box installation position are arranged along the conveying direction. Then, at each station, only one junction box can be processed at a time, and the efficiency is still low. Moreover, the solution cannot process wireless junction boxes and wired junction boxes simultaneously. Summary of the Invention

[0006] The technical problem to be solved by the utility model is the low working efficiency of the existing junction box automatic installation machine and the inability to process junction boxes with and without connection heads simultaneously.

[0007] To solve the problems existing in the prior art, the present utility model provides a junction box preparation and feeding device, which includes a junction box preparation device and a junction box feeding device; the junction box preparation device includes a first manipulator, and on both sides of the first manipulator along the Y-axis direction, there is a wired junction box bin respectively. On one side of the wired junction box bin along the traveling direction of the photovoltaic panel, there is a conveyor belt device. At the output end of the conveyor belt device, there is a wired junction box positioning seat. Outside the conveyor belt device, there is also a wireless junction box supply device; the junction box feeding device includes two second manipulators arranged oppositely, and at the execution end of the second manipulator, there is a junction box handling assembly; the first manipulator neatly arranges the wired junction boxes in the wired junction box bin onto the conveyor belt device, and the first manipulator also places the wired junction boxes on the conveyor belt device onto the wired junction box positioning seat; the second manipulator places the wired junction boxes on the wired junction box positioning seat and / or the wireless junction boxes on the wireless junction box supply device onto the solar panel, so that the lead ends of the bus bars penetrate into the junction boxes.

[0008] In the above structure, the first manipulator can neatly arrange the wired junction boxes in the wired junction box bin onto the conveyor belt device, which is convenient for transportation and subsequent positioning. Then, the first manipulator places the wired junction boxes on the conveyor belt device onto the wired junction box positioning seat, which is convenient for the second manipulator to grab. The wireless junction box supply device can automatically continuously transport the wireless junction boxes to a position convenient for the second manipulator to grab; the two second manipulators arranged oppositely can grab the wired junction boxes and / or wireless junction boxes according to the actual requirements of the processed solar panel. In this solution, the two second manipulators can be started simultaneously, and grab multiple wired junction boxes and / or wireless junction boxes and place them on the photovoltaic panel at the same time, so that the processing efficiency is high.

A rack driving device capable of driving the first rack 3241 or the second rack 3242 to perform a translational motion is provided on the second clamping bracket 323.

[0024] In this embodiment, the rack driving device is a cylinder 3243. The cylinder body of the cylinder 3243 is provided on the second clamping bracket 323, and the piston rod of the cylinder 3243 is connected to the first rack 3241 or the second rack 3242.

[0025] Second clamping plates 3244 are provided on both the first rack 3241 and the second rack 3242, and second clamping blocks 3245 are provided at the ends of the two second clamping plates 3244. The two second clamping blocks 3245 are arranged oppositely.

[0026] In this embodiment, the second clamping block 3245 is made of urethane rubber, and anti-slip grooves are provided on the two opposite surfaces of the two second clamping blocks 3245.

[0027] With the above structure, the first manipulator 311 can neatly arrange the wired wiring boxes in the wired wiring box bin 312 onto the conveyor belt device 313, which is convenient for conveying and the next positioning. Then, the first manipulator 311 places the wired wiring boxes on the conveyor belt device 313 onto the wired wiring box positioning seat 314, which is convenient for the second manipulator 321 to grab.
