Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a photovoltaic component stacking and strapping packaging line. Background Art

[0002] Photovoltaic modules (also known as solar panels) are devices that convert solar energy directly into electrical energy. They are mainly composed of multiple photovoltaic cells, glass, backplane, frame and junction box. Photovoltaic modules play a core role in solar power generation systems, converting the radiation energy of sunlight into electrical energy, thereby realizing the utilization of solar energy. Because the main part of photovoltaic modules is glass, they are fragile. Photovoltaic modules are often used in combination, so during the process of unloading and transportation, photovoltaic modules need to be stacked and packaged to prevent damage. And sometimes photovoltaic modules need to be packed together in groups of two after packing, so that they can be better transported.

[0003] Chinese patent CN216070662U discloses an automatic packaging line, which only packs glass stacks together with tape and film. However, it only packs a lot of glass together, and there is no boxing process, no pallets are used, and there is no need to pack multiple boxes together, which is not convenient for forklift transportation.

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

[0007] Specifically, a centering mechanism is provided on the feeding side of each packaging mechanism for returning the transport center of the photovoltaic module box to the center line of the box transport line.

[0008] Specifically, a first transfer mechanism is provided below the box conveyor line, and the M-shaped strapping mechanisms are provided in pairs at the front and rear sides of the side stations of the first transfer mechanism.

[0009] Specifically, a second transfer mechanism is provided below the station where the short-side strapping mechanism is located, the conveying direction of the second transfer mechanism is perpendicular to the conveying direction of the box conveyor line, and a code scanning and mark scanning mechanism is provided on the side station of the second transfer mechanism.

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

[0011] This photovoltaic module stacking and strapping packaging line can bundle and wrap photovoltaic module boxes in groups of two. The whole is tight and stable, which can avoid the risk of tipping over and ensure the safe transportation of photovoltaic modules after leaving the factory. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described in detail below in conjunction with specific embodiments.

[0025] Example:

[0026] like Figure 1 and Figure 2As shown, the photovoltaic module stacking and strapping packaging line 1 of the utility model comprises a box conveyor line 11 for conveying photovoltaic module boxes 2 and a stacking mechanism 12 and a plurality of packaging mechanisms sequentially arranged along the conveying direction of the box conveyor line 11, wherein the packaging mechanisms are a long-side strapping mechanism 13a, a M-shaped strapping mechanism 13b, a top film applying mechanism 13c, a short-side strapping mechanism 13d and a film winding mechanism 13e.

[0027] The photovoltaic module boxes 2 are first passed over the box conveyor line 11 one by one in the form of single boxes. When the first photovoltaic module box reaches the station of the stacking mechanism 12, the stacking mechanism 12 lifts it to the top, and the second photovoltaic module box is moved to the bottom of the previous photovoltaic module box. In this way, the stacking mechanism 12 places the first photovoltaic module box on the second photovoltaic module box. There is a wooden pallet 21 at the bottom of the photovoltaic module box 2. The wooden pallet 21 and the photovoltaic module box 2 are integrated in the packaging, so the wooden pallet 21 of the first photovoltaic module box is now on the top of the second photovoltaic module box. Then the two photovoltaic module boxes 2 are moved together to the station of the long side threading and strapping mechanism 13a. The long side threading and strapping mechanism 13a is responsible for binding the upper part of the photovoltaic module box below with the wooden pallet 21 of the photovoltaic module box above. At this time, the two photovoltaic module boxes form a whole with a preliminary fixed relative position. Then the two photovoltaic module boxes 2 are moved together to the station where the M-shaped strapping mechanism 13b is located, so that the four corners of the wooden pallet 21 of the upper and lower boxes are fixed by the first packaging tape 3a in an oblique manner, so that the upper and lower boxes are completely fixed. Then the two photovoltaic module boxes 2 are moved together to the station of the top film applying mechanism 13c, and the top film applying mechanism 13c cuts the top film 4a to a fixed length and covers it on the top of the two photovoltaic module boxes 2, and the two ends of the top film 4a hang down from the two sides of the box respectively. Then through the short side strapping mechanism 13d, the short side strapping mechanism 13d uses the second packaging tape 3b to bundle the top film 4a and the two photovoltaic module boxes 2 together. The two photovoltaic module boxes 2 continue to move to the station where the film winding mechanism 13e is located, and the sides of the two photovoltaic module boxes 2 are tightly wrapped by the side film 4b, and the two ends of the top film 4a are also pressed inside the side film 4b. This photovoltaic module stacking strapping packaging line can bundle and wrap the photovoltaic module boxes in groups of two. The whole is tight and stable, which can avoid the risk of tipping over and ensure the safe transportation of photovoltaic modules after leaving the factory.

[0028] like Figure 1 As shown, the feeding side of each packaging mechanism is provided with a centering mechanism 111 for returning the conveying center of the photovoltaic module box 2 to the center line of the box conveying line 11.

[0029] The length of the box conveyor line 11 is very long, and there is always an error in the conveying direction. The photovoltaic module boxes 2 are mostly in a stacked state, so the photovoltaic module boxes 2 must be conveyed and offset to one side of the box conveyor line 11, which will cause the upper box to overturn and avoid damage to the photovoltaic modules. The centering mechanism 111 is symmetrically squeezed on both sides of the photovoltaic module box 2 to center. The photovoltaic module box 2 needs to be centered before each packaging step, especially the edges between the upper and lower boxes always need to be aligned, otherwise it cannot be tied with packaging bags and packaging films. Therefore, before each packaging step, the centering mechanism 111 needs to adjust the photovoltaic module box 2 to the center line of the box conveyor line 11, which can also prevent the photovoltaic module box 2 from deviating during transportation.

[0030] like Figure 1 As shown, a first transfer mechanism 14a is provided below the box conveyor line 11, and a cross-shaped strapping mechanism 13b is provided in pairs at the front and rear sides of the side stations of the first transfer mechanism 14a.

[0031] In this embodiment, the long side extension direction of the photovoltaic module box 2 is the conveying direction of the box conveyor line 11, and the position of the cross-shaped strapping is on both sides of the short side of the photovoltaic module box 2. The cross-shaped strapping mechanism 13b cannot be set on the conveying path of the photovoltaic module box 2, so the first transfer mechanism 14a must first move the photovoltaic module box 2 outside the box conveyor line 11, and then the cross-shaped strapping mechanism 13b can be used for strapping. After the cross-shaped strapping is completed, the photovoltaic module box 2 is sent back to the box conveyor line 11.

[0032] like Figure 1 As shown, a second transfer mechanism 14b is provided below the station where the short-side strapping mechanism 14a is located, and the conveying direction of the second transfer mechanism 14b is perpendicular to the conveying direction of the box conveyor line 11. A code scanning and mark scanning mechanism 15 is provided on the side station of the second transfer mechanism 14b.

[0033] The code scanning and label scanning mechanism 15 also cannot affect the conveying path of the photovoltaic module box 2, so it is necessary to move the photovoltaic module box 2 out of the box conveying line 11 through the second transfer mechanism 14b, and then return to the box conveying line 11 after completing the code scanning and label scanning.

[0034] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
