Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic equipment technology, specifically to a junction box preparation and feeding device and its working method. Background Technology

[0002] During the production of solar photovoltaic panels, after the silicon wafer array is arranged on a glass plate, multiple arrayed silicon wafers need to be connected together by busbars. Subsequently, the junction box needs to be fixed to 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 control equipment, etc.

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

[0004] Patent application CN115173176A discloses an automatic junction box installation machine, comprising a conveying unit and an operating unit. The conveying unit's conveying path includes a positioning station, a lead wire shaping station, a junction box installation station, and a welding station. The conveying unit steps along a battery string assembly, moving one junction box installation position from the current operating station to the next with each step. The operating unit includes a positioning mechanism, a lead wire shaping mechanism, a junction box installation mechanism, and a welding mechanism. The positioning mechanism, located above the positioning station, positions the junction box installation position. The lead wire shaping mechanism, located above the lead wire shaping station, removes the adhesive tape from the junction box installation position and shapes the lead wire. The junction box installation mechanism, located above the junction box installation station, installs the junction box onto the installation position. The welding mechanism, located above the welding station, performs welding on the junction box installation position. This machine achieves automatic junction box installation, improving installation efficiency.

[0005] However, this scheme is designed for the first junction box mounting position, the second junction box mounting position, and the third junction box mounting position to be arranged along the conveying direction. Therefore, only one junction box can be processed at each station at a time, which is still inefficient. Furthermore, the scheme cannot process wireless junction boxes and wired junction boxes at the same time. Summary of the Invention

[0006] The present invention aims to solve the technical problems of low working efficiency and inability to process junction boxes with and without connectors simultaneously in the existing automatic junction box installation machine.

[0007] To address the problems existing in the prior art, the present invention provides a junction box preparation and loading device, including a junction box preparation device and a junction box loading device. The junction box preparation device includes a first robotic arm, with a wired junction box compartment on each side along the Y-axis of the first robotic arm. A conveyor belt device is provided on one side of the wired junction box compartment along the travel direction of the photovoltaic panel. A wired junction box positioning seat is provided at the output end of the conveyor belt device, and a wireless junction box supply device is also provided on the outside of the conveyor belt device. The junction box loading device includes two second robotic arms arranged opposite each other, with a junction box handling component at the execution end of the second robotic arms. The first robotic arm neatly arranges the wired junction boxes in the wired junction boxes onto the conveyor belt device, and also places the wired junction boxes on the conveyor belt device onto the wired junction box positioning seat. The second robotic arm 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 end of the busbar is inserted into the junction box.

[0008] In the above structure, the first robotic arm can neatly arrange the wired junction boxes in the wired junction box compartment onto the conveyor belt device for easy transport and subsequent positioning. Then, the first robotic arm places the wired junction boxes on the conveyor belt device onto the wired junction box positioning seat for easy gripping by the second robotic arm. The wireless junction box supply device can automatically and continuously transport the wireless junction boxes to a position convenient for the second robotic arm to grip. The two opposing second robotic arms can grip the wired junction boxes and / or wireless junction boxes according to the actual needs of the solar panels being processed. In this solution, the two second robotic arms can be started simultaneously, gripping multiple wired junction boxes and / or wireless junction boxes and placing them on the photovoltaic panels at the same time, resulting in high processing efficiency.

[0009] The present invention also provides a method for operating a junction box preparation and feeding device, comprising the following steps:

[0010] S1. Place two wired junction box compartments filled with wired junction boxes on both sides of the first robotic arm; fill the wireless junction box supply device with wireless junction boxes.

[0011] S2. Start the first robotic arm and conveyor belt device. The first robotic arm transports the wired junction box in the wired junction box compartment to the conveyor belt device.

[0012] S3. Start the wired junction box positioning seat. The first robot arm will transport the wired junction box on the conveyor belt device to the wired junction box positioning seat.

[0013] S4. Activate the wireless junction box supply device and the second robotic arm; the second robotic arm places the wired junction box on the wired junction box positioning seat and / or the wireless junction box on the wireless junction box supply device onto the solar panel.

[0014] Using this method, the first robotic arm can quickly pick up wired junction boxes from the wired junction box compartment, supplying them via two conveyor belts. Positioned by the wired junction box positioning seats, two second robotic arms can quickly pick up the wired junction boxes from the positioning seats and transport them to the solar panels. Simultaneously, a wireless junction box supply device continuously provides wireless junction boxes to the second robotic arms. Based on the needs of the produced solar panels, the number and placement of both wired and wireless junction boxes can be controlled through program settings, achieving the goal of simultaneously processing solar panels requiring both types of junction boxes. This method is fast and efficient. Attached Figure Description

The first rack 3241 and the second rack 3242 are slidably mounted on the second clamping bracket 323 via a slide rail and a slider. The first rack 3241 and the second rack 3242 are arranged relatively parallel to each other. Both the first rack 3241 and the second rack 3242 mesh with the gear 3240. A rack drive device is provided on the second clamping bracket 323 to drive the first rack 3241 or the second rack 3242 to translate.

[0030] In this embodiment, the rack and pinion drive device is a cylinder 3243. The cylinder body of the cylinder 3243 is mounted 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.

[0031] A second clamping plate 3244 is provided on both the first rack 3241 and the second rack 3242, and a second clamping block 3245 is provided at the end of both second clamping plates 3244, with the two second clamping blocks 3245 arranged opposite to each other.

[0032] 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.

[0033] In the above structure, the first robotic arm 311 can neatly arrange the wired junction boxes in the wired junction box compartment 312 onto the conveyor belt device 313 for easy transport and subsequent positioning. Then, the first robotic arm 311 places the wired junction boxes on the conveyor belt device 313 onto the wired junction box positioning seat 314 for easy gripping by the second robotic arm 321. The wireless junction box supply device 315 can automatically and continuously transport the wireless junction boxes to a position convenient for the second robotic arm 321 to grip.
