Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a single-tray strapping packaging line for photovoltaic components. 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 unloading and transportation process, photovoltaic modules need to be stacked and packaged to prevent damage.

[0003] The Chinese patent CN215753294U applied by our company discloses a new type of large-size photovoltaic module packaging line, which can complete multiple packaging operations such as strapping, cartoning, and film laminating. Photovoltaic modules are transported on iron pallets and wooden pallets. However, it does not reflect how to recycle the iron pallets. Because the iron pallets are heavy and there are many of them, if they are accumulated and transported by forklifts, the continuity is not good. Moreover, if the iron pallets are damaged, it is not convenient to remove them immediately. Once they are reused, there is a risk of tipping over, which will cause damage to the photovoltaic modules.

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

[0009] The transfer assembly includes a transfer robot located at the entrance side of the second pallet conveying line, and the outer side of the transfer robot is also provided with a second pallet placement area and a partition placement area.

[0010] Specifically, the first pallet conveying section is provided with a first strapping mechanism for the long side of the box, and the 90° flipping pallet mechanism is located in the discharge direction of the first strapping mechanism for the long side of the box.

[0038] The utility model is further described in detail below in conjunction with specific embodiments.

[0039] Example:

[0040] like Figures 1 to 5 As shown, the photovoltaic module single-pallet strapping packaging line 1 of the utility model includes a module loading unit 11, a first pallet conveyor line 12, a second pallet conveyor line 13, a first strapping mechanism 14a for the long side inside the box, a second strapping mechanism 14b for the long side inside the box, a strapping mechanism 14c for the short side inside the box, a horizontal strapping mechanism 14d inside the box, a strapping mechanism 14e for the long side outside the box, a strapping mechanism 14f for the short side outside the box, a 90° flipping pallet mechanism 15, a transfer component 16, a box-covering mechanism 17, a paper placing and edge-protecting mechanism 18, a code scanning mechanism 134 and a marking mechanism 135.

[0041] The conveying of the whole photovoltaic module single-tray packing line 1 is mainly divided into two sections. The first section uses the iron first pallet 3a to convey the stacked photovoltaic modules 2, which flows through the first pallet conveyor line 12, and the second section uses the wooden second pallet 3b to convey the stacked photovoltaic modules 2, which flows through the second pallet conveyor line 13. The first pallet 3a only plays the role of supporting and preventing collision, and is not fixed to the photovoltaic module 2. After the photovoltaic module 2 is transferred to the second pallet 3b, the first pallet 3a is returned; the second pallet 3b will be packaged together with the photovoltaic module 2 and finally output.

[0042] like Figure 2 As shown, the component loading line 11 includes a turnover mechanism 111 , a direct loading line 112 located in one feeding direction of the turnover mechanism 111 , and a grading line 113 located in another feeding direction. The outlet of the turnover mechanism 111 is connected to the inlet of the first pallet conveying line 12 .

[0043] The photovoltaic modules 2 are stacked horizontally on the first pallet 3a. The two are taken as a whole. There are two ways to load the materials: direct loading and graded loading. Direct loading refers to a loading method in which the photovoltaic modules 2 are fed into the material from the entrance of the direct feeding line 112 by a forklift without judging the performance of the photovoltaic modules 2; graded loading refers to a loading method in which photovoltaic modules 2 with similar performance are grouped together based on the performance judgment of the photovoltaic modules 2, and then fed into the material from the entrance of the graded line 113. In both loading methods, the first pallet 3a and the photovoltaic modules 2 as a whole will arrive at the turnover mechanism 111. The turnover mechanism 111 adjusts the overall posture, and then adjusts the angle, and transports them to the first pallet conveyor line 12.

[0044] like Figure 3As shown, the first pallet conveyor line 12 includes a first pallet conveying section 121, a first pallet lower board section 122 located in the outlet direction of the first pallet conveying section 121, and a first pallet reflux section 123 located on the side of the outlet direction of the first pallet conveying section 121, the first strapping mechanism 14a on the long side of the box and the 90° flipping pallet mechanism 15 are successively arranged on the first pallet conveying section 121, the inlet of the second pallet conveyor line 13 is located on the discharge side of the 90° flipping pallet mechanism 15, and the outlet of the first pallet reflux section 123 returns to the dividing line 113.

[0045] The reason why the first pallet 3a is an iron pallet is that it is used as a carrier of the photovoltaic module 2 in the factory and needs to be used continuously, so it focuses on being more durable. Therefore, after the first pallet 3a completes the task of conveying the photovoltaic module 2 in the first pallet conveying section 121, it needs to be reused from the first pallet reflux section 123. If the first pallet 3a is found to be able to be used normally, the first pallet is used to return to the grading line 123 to improve the degree of automation of the packaging line. However, the first pallet 3a still has its service life, so if it is found to be seriously damaged after it is used up, it is judged to be unqualified and needs to be moved to the lower plate section 122 of the first pallet for collection to avoid the risk of the photovoltaic module 2 being overturned and damaged by the unqualified first pallet 3a. The photovoltaic module 2 needs to be flipped 90° along the long side of the photovoltaic module 2 from the first pallet conveying line 12 to the second pallet conveying line 13, and the photovoltaic module 2 is in a vertical state after flipping. In order to prevent the photovoltaic modules 2 from being scattered, the first strapping mechanism 14a on the long side of the box needs to be used to strap the entire stack of photovoltaic modules 2 before turning over, that is, several strapping strips 6 are tied from both sides of the long sides of the photovoltaic modules 2 without being tied to the first pallet 3a. In this way, when turning over by 90 degrees, all photovoltaic modules 2 will move as a whole and transfer to the second pallet 3b that is already waiting at the entrance of the second pallet conveyor line 13.

[0046] like Figure 5 As shown, the transfer assembly 16 includes a transfer robot 161 located at the entrance side of the second pallet conveying line 13 , and the outer side of the transfer robot 161 also has a second pallet placement area 162 and a partition placement area 163 .

[0047] The transfer robot 161 needs to first move the second pallet 3b from the second pallet placement area 162 to the entrance of the second pallet conveyor line 13, and then move the partition 41 from the partition placement area 163 to the second pallet 3b, and then the photovoltaic module 2 can be put into place after being flipped over. The second pallet 3b is made of a wooden pallet because the wooden pallet is packaged together with the photovoltaic module 2 in the final package. Compared with iron pallets, wooden pallets are softer, have lower density and lower cost. The partition 41 serves as the bottom support structure of the photovoltaic module 2 after flipping. After the carton 42 is packaged, the photovoltaic module 2 can be completely surrounded to achieve isolation between the inside and outside of the carton 42.

[0048] like Figure 4 As shown, the second pallet conveying line 13 includes a second pallet conveying section 131 , a material unloading section 132 located at the exit of the second pallet conveying section 131 , and a repair section 133 located at the side of the exit of the second pallet conveying section 131 .

[0049] The packages with normal packaging will be removed from the unloading section 132, and the packages with abnormal packaging will be sent to the repair section 133 for repair.

[0050] like Figure 4 As shown, the second strapping mechanism 14b for the long side inside the box, the code scanning mechanism 134, the marking mechanism 135, the horizontal strapping mechanism 14c inside the box, the box-covering mechanism 17, the horizontal strapping mechanism 14d outside the box, the strapping mechanism 14c for the long side outside the box, and the strapping mechanism 14d for the short side outside the box are sequentially arranged on the second pallet conveying section 131, and the paper placing and edge protecting mechanism 18 is located at the same station of the horizontal strapping mechanism 14d outside the box.

[0051] After the bundled photovoltaic components 2 are transferred to the partition 41, the second long side strapping mechanism 14b inside the box also straps the photovoltaic components 2 and the partition 41; then the photovoltaic components 2 are strapped horizontally to prevent sliding between the photovoltaic components 2; then the code scanning mechanism 134 scans the photovoltaic components 2, and the marking mechanism 135 marks the partition 111; the box-putting mechanism 17 puts the carton 42 on the outer cover of the stack of photovoltaic components 2, and the paper guarding mechanism 18 places paper guards 5 on the four vertical sides of the carton 42, and then the horizontal strapping mechanism 14d outside the box binds the four paper guards 5 to the carton 42 together; finally, the long side strapping mechanism 14c outside the box and the short side strapping mechanism 14d outside the box complete the strapping in two directions respectively, so that the carton 42 and the second pallet 3b are fixed as a whole, and the material can be discharged at this time. The paper box 42 protects the entire outer surface of the photovoltaic module 2, and the paper guard 5 thickens the four corners of the photovoltaic module 2 that are easily damaged by collision. The packaging process is completed automatically, with high work efficiency, reliable packaging, and product safety.

[0052] 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.
