Detailed Embodiments

[0053] The following is a detailed description of the implementation of the present invention in conjunction with the accompanying drawings, but they do not constitute a limitation of the present invention and are only given as examples. At the same time, the advantages of the present invention are made clearer and easier to understand through the description.

[0054] Referring to the attached drawings, it can be seen that the side-opening photovoltaic assembly frame dismantling equipment disclosed in the present invention includes a workbench 2, a follow-up positioning seat 7 is arranged on the upper surface of the workbench 2, which plays the role of assisting the manipulator in positioning, and a flip seat 8 is connected to the side of the workbench 2, and the flip seat 8 is connected to the push frame 4, and the push frame 4 is connected to the large pressure frame 5. The large pressure frame 5 is closed and directly applies a downward pressing force to the photovoltaic assembly. A manipulator 3 is arranged in front of the frame dismantling equipment, and a photovoltaic assembly placement rack 1 is arranged on the left side of the manipulator 3. This frame dismantling equipment has a compact structure, stable function and a large advantage in terms of floor space. In the photovoltaic assembly frame dismantling equipment of the present invention, the photovoltaic assembly is loaded and unloaded by the manipulator 3, the manipulator 3 falls at a suitable position, and then the push frame 4 is pushed by the hydraulic cylinder 9 to rotate, and the push frame 4 is connected to the large pressure frame 5 to close from the side to press the photovoltaic assembly, and the oil cylinder 21 in the hollow plate-shaped box body 2A of the workbench 2 is pushed out horizontally to remove the aluminum frame and the junction box, and the manipulator unloads the material after the frame dismantling work is completed. No adjustment is required during the dismantling process, and the full-automatic one-time dismantling can greatly improve the efficiency of frame dismantling.

[0055] The photovoltaic module placement rack 1 is provided with positioning rods 11 on two connected sides, and the positioning rods 11 limit the photovoltaic modules to be stacked in a consistent manner, and the servo motor 12 drives the screw rod 16 to drive the scissor arms to rise or fall (such as Figure 7 shown).

[0056] The manipulator 3 in the present invention and the photovoltaic module placement rack 1 located on the right side of the manipulator form a fully automatic loading system. The manipulator 3 can use the suction cup 31 to firmly suck the photovoltaic module, and then transfer it to the workbench through electrical control. The entire work process of the manipulator 3 only needs to locate the photovoltaic module placement rack 1 and the center position of the workbench. At the same time, the manipulator is electrically controlled to achieve two-point one-line rapid positioning and work (different from the existing technology on the market that needs to be placed on the conveyor belt first, and then the conveyor belt transfers the photovoltaic module to the frame removal work area). The entire work process can be completed without manual intervention. This solution not only significantly improves the accuracy of photovoltaic module positioning but also improves the efficiency of frame removal.

[0057] Large and small pressure blocks are installed on the lower surface of the large pressure frame 5. The inner cavities of the large and small pressure blocks are connected to polytetrafluoroethylene pads to protect the photovoltaic components. The large pressure frame is connected to the push frame, and the push frame is connected to the flip seat. The push frame is pushed by the hydraulic cylinder and can rotate freely at a certain angle to drive the large pressure frame to rotate until the photovoltaic components are pressed tightly.

[0058] The frame removal mechanism consists of a hollow plate-shaped box body 2A, a long push rod 23, a short push rod 24, a scraper 25 and an oil cylinder 21. A plurality of oil cylinders 21 and guide shafts 22 are arranged in the hollow plate-shaped box body 2A. Each guide shaft 22 is fixed by a linear bearing to ensure that the oil cylinders in four directions can horizontally extend. Each aluminum frame corresponds to an oil cylinder 21. The output shaft of the oil cylinder 21 horizontally extends to drive the push rod and the scraper 25 to remove the aluminum frames and junction boxes on the four sides of the photovoltaic module, improving the frame removal effect.

[0059] Receiving frames with rollers are arranged under the four sides of the workbench, facilitating the movement and replacement of the receiving frames.

[0060] The frame removal method of the side-opening photovoltaic module frame removal equipment of the present invention includes the following steps:

[0061] Step 1: Manually stack the photovoltaic modules 10 on the photovoltaic module placement rack 1.

[0062] Step 2: The manipulator 3 firmly sucks the photovoltaic module 10 on the photovoltaic module placement rack 1 through the suction cup 31, and then stably and quickly places the photovoltaic module 10 at the center position of the workbench 2. At the same time, the servo motor 12 drives the photovoltaic module placement rack 1 to increase the relative height, ensuring that the photovoltaic modules 10 to be processed later can have the same height position as the photovoltaic modules 10 processed earlier, and the manipulator can suck the remaining photovoltaic modules 10 at the same fixed position.

[0063] Step 3: The push frame is driven by a hydraulic cylinder to rotate freely by a certain angle, driving the large pressing frame to slowly close until it presses the photovoltaic module 10, and stops and presses the photovoltaic module 10 at a suitable position.

[0064] Step 4: The output shaft of the oil cylinder 21 in the hollow plate-shaped box body 2A horizontally extends to drive the push rod and the scraper 25 to remove the aluminum frames and junction boxes on the four sides of the photovoltaic module 10, and the aluminum frames and junction boxes respectively fall into the corresponding receiving frames 6.

[0065] Other parts not described belong to the prior art.
