Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic module encapsulant film separation equipment, specifically a photovoltaic module encapsulant film separation equipment. Background Technology

[0002] In recent years, the photovoltaic industry has developed rapidly as a clean and renewable energy source. As of the first half of 2023, my country's installed capacity of photovoltaic modules has exceeded 470 million kilowatts, ranking first in the world for eight consecutive years. How to recycle and reuse waste photovoltaic modules has become an increasingly prominent issue. Existing methods generally decompose and recycle photovoltaic modules through high-temperature incineration and chemical treatment.

[0003] In existing photovoltaic module encapsulant separation processes, separation is achieved using a blade. However, due to the high adhesion of the entire encapsulant film flat against the glass surface, separation is quite difficult. Typically, heating is used to soften the adhesive before separation with the blade. After separation, the encapsulant film needs to be removed promptly to prevent it from re-adheding due to cooling. Therefore, we propose a photovoltaic module encapsulant film separation device to solve the aforementioned problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module encapsulant film separation device, comprising a frame and a fixing frame;

[0006] The frame is provided in two sets, and multiple sets of guide rollers are rotatably arranged between the two sets of the frame. Two sets of preheating rollers are provided on one side of the guide rollers on the left side of the frame. A feeding belt assembly is provided on one side of the preheating rollers.

The upper end of the rotating shaft is connected to the center of the bottom of the mounting plate. The top of both sides of the mounting plate is equipped with a first cylinder, and the mounting frame is located on the same side below the two sets of first cylinders. The output end of the first cylinder is connected to the center of the mounting frame. Multiple sets of vacuum suction cups are located on both sides of the mounting frame.

Two sets of second cylinders are provided on both sides of the assembly. Two sets of pressure plates are provided below the assembly. The output ends of the two sets of second cylinders are connected to the top of the pressure plate on the same side.

[0009] As a preferred technical solution of this utility model, the separation component includes a third cylinder, a moving block, a fourth cylinder, a mounting base, and a hot cutting blade.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this photovoltaic module encapsulant film separation equipment, the photovoltaic panel is guided by guide rollers, and preheated by preheating rollers during the movement of the photovoltaic panel, which softens the adhesive at the encapsulant film. After the photovoltaic panel is guided above the feeding belt assembly, the adhesive film is separated by the cooperation of the fixing assembly and the separation assembly. After separation, the photovoltaic panel is guided again by guide rollers. At this time, the mounting frame is lowered by the first cylinder. The adhesive film is then adsorbed by multiple vacuum suction cups below the mounting frame, and the separated adhesive film is removed from the surface of the photovoltaic panel. The separated adhesive film should be removed in time during use to avoid the adhesive film from cooling again and sticking due to failure to remove it in time, which would require secondary separation.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a photovoltaic module encapsulant film separation device, including a frame 1 and a fixing frame 2;

[0022] The frame 1 has two sets of guide rollers 3 rotating between the two sets of frame 1. Each pair of adjacent guide rollers 3 has a pulley at one end, and the two pulleys are connected by a transmission belt 10. Two sets of preheating rollers 4 are located on the left side of the guide rollers 3 of the frame 1. Drive gears 11 are installed at one end of each set of preheating rollers 4, and the two sets of drive gears 11 mesh with each other. A feeding belt assembly 5 is located on one side of the preheating rollers 4. A fixing plate 6 is located in the middle of the feeding belt assembly 5 on the inner side wall of the two sets of frame 1. A fixing assembly 7 is located above the frame 1. The fixing assembly 7 includes an assembly 701, a second cylinder 702, and a pressure plate 703. An assembly 701 is located above the feeding belt assembly 5, and both ends of the assembly 701 are connected to the outer side wall of the two sets of frame 1. Two sets of second cylinders 702 are located on both sides of the assembly 701. 02. Two sets of pressure plates 703 are provided below the assembly 701. The output ends of the two sets of second cylinders 702 are connected to the top of the pressure plates 703 on the same side. The frame 1 is provided with a separation component 8. The separation component 8 includes a third cylinder 801, a moving block 802, a fourth cylinder 803, a mounting base 804, and a hot cutting blade 805. The top of the two sets of frame 1 is provided with a third cylinder 801. The top of the two sets of frame 1 is provided with a moving block 802. The output end of the third cylinder 801 is connected to the moving block 802. The fourth cylinder 803 is provided on the moving block 802. The mounting base 804 is provided below the moving block 802. The output end of the fourth cylinder 803 is connected to the top of the mounting base 804. The hot cutting blade 805 is detachably provided in the mounting base 804. The film taking component 9 is provided above the fixed frame 2.

[0023] The guide roller 3 is driven by a motor to rotate, and the transmission belt 10 on one side of the guide roller 3 rotates synchronously, so that multiple guide rollers 3 rotate synchronously. At this time, after the photovoltaic panel is placed above the guide roller 3 on the left side of the frame 1, it enters the middle position of the preheating rollers 4 on both sides. At the same time, the motor drives the preheating roller 4 to rotate, so that the drive gear 11 at one end of the preheating roller 4 rotates synchronously, so that the preheating rollers 4 on both sides rotate. The preheating roller 4 heats the photovoltaic panel, so that the internal adhesive is preheated and softened. At this point, the preheated photovoltaic panel reaches the surface of the feeding belt assembly 5. The feeding belt assembly 5 consists of a drive roller feeding belt. The drive roller is driven to rotate, causing the feeding belt to rotate and transport the photovoltaic panel. When the photovoltaic panel is transported to the middle position of the feeding belt assembly 5, the second cylinder 702 on the left side of the assembly 701 is activated to drive the pressure plate 703 to descend. This causes the pressure plate 703 to cooperate with the fixing plate 6 in the middle position of the feeding belt assembly 5 in the frame 1 to fix the photovoltaic panel. Then, the fourth cylinder 803 is activated to drive the mounting base 804 to descend, causing the hot cutting blade 805 mounted above the mounting base 804 to be positioned... Adjustment: According to different photovoltaic panels, the hot cutting blade 805 is adjusted to the bonding point between the photovoltaic panel and the adhesive film. At this time, the third cylinder 801 drives the moving block 802 to move, so that the hot cutting blade 805 separates the adhesive film and the panel. When the hot cutting blade 805 moves to the lower middle of the assembly 701, the second cylinder 702 on the left side of the assembly 701 rises, and the second cylinder 702 on the right side drives the pressure plate 703 to descend. After continuing to fix the photovoltaic panel with the fixing plate 6, the hot cutting blade 805 continues to move, completing the step of separating the adhesive film on the entire surface of the photovoltaic panel.

[0024] The film-taking assembly 9 includes a rotating shaft 901, a mounting plate 902, a first cylinder 903, a mounting frame 904, and a vacuum suction cup 905. The rotating shaft 901 is rotatably mounted on the upper end of the fixed frame 2. The mounting plate 902 is mounted above the rotating shaft 901. The upper end of the rotating shaft 901 is connected to the center of the bottom of the mounting plate 902. The top of both sides of the mounting plate 902 is equipped with a first cylinder 903. The mounting frame 904 is located on the same side below the two sets of first cylinders 903. The output end of the first cylinder 903 is connected to the center of the mounting frame 904. Multiple sets of vacuum suction cups 905 are provided on both sides of the mounting frame 904. A first gear 14 is mounted on the rotating shaft 901. A rotating rod 12 is rotatably mounted on the fixed frame 2. A second gear 13 that meshes with the first gear 14 is mounted on the rotating rod 12. Limiting rods 15 are slidably mounted through both sides of the mounting plate 902. The lower end of the limiting rod 15 is connected to the top of the mounting frame 904.

[0025] After separation, the photovoltaic panel is conveyed to the guide roller 3 on the right side of the frame 1 by the feeding belt assembly 5. Then, the first cylinder 903 drives the mounting frame 904 below to descend. At the same time, the limiting rod 15 above the mounting frame 904 slides within the mounting plate 902, so that the multiple sets of vacuum suction cups 905 on both sides of the mounting frame 904 come into contact with the adhesive film separated from the photovoltaic panel surface. The vacuum suction cups 905 adsorb the adhesive film. The power source for the vacuum suction cups 905 is provided externally. After the adhesive film is adsorbed, the first cylinder 903 drives the mounting frame 904 to rise. The stepper motor drives the rotating rod 12 to rotate, and the rotating rod 12 simultaneously drives the second gear 13 to rotate. The second gear 13 synchronously drives the first gear 14 to rotate, so that the first gear 14 drives the rotating shaft 901 to rotate, and the rotating shaft 901 drives the mounting plate 902 to rotate, rotating the mounting bracket 904 on the other side above the frame 1. The mounting bracket 904 with the adhesive film is moved to the outside of the frame 1 and can be released by the vacuum suction cup 905 to put down the adhesive film for collection. The photovoltaic panel with the adhesive film separated is continued to be transported to the subsequent equipment for processing by the guide roller 3.

[0026] Working principle: When using the photovoltaic module encapsulant separation equipment, the motor drives the guide roller 3 to rotate, and the transmission belt 10 on one side of the guide roller 3 rotates synchronously, so that multiple guide rollers 3 rotate synchronously. At this time, after the photovoltaic panel is placed above the guide roller 3 on the left side of the frame 1, it enters the middle position of the preheating rollers 4 on both sides. At the same time, the motor drives the preheating roller 4 to rotate, so that the drive gear 11 at one end of the preheating roller 4 rotates synchronously, so that the preheating rollers 4 on both sides rotate. The preheating rollers 4 heat the photovoltaic panel, so that the internal adhesive is preheated and softened.At this point, the preheated photovoltaic panel reaches the surface of the feeding belt assembly 5. The feeding belt assembly 5 consists of a drive roller feeding belt. The drive roller is driven by a drive device to rotate, causing the feeding belt to rotate and transport the photovoltaic panel. When the photovoltaic panel is transported to the middle position of the feeding belt assembly 5, the second cylinder 702 on the left side of the mounting accessory 701 is activated to drive the pressure plate 703 to descend. This allows the pressure plate 703 to cooperate with the fixing plate 6 in the middle position of the feeding belt assembly 5 in the frame 1 to fix the photovoltaic panel. Then, the fourth cylinder 803 is activated to drive the mounting base 804 to descend, allowing the position of the hot cutting blade 805 mounted on the mounting base 804 to be adjusted according to the different... The hot cutting blade 805 is adjusted to the bonding point between the photovoltaic panel and the adhesive film. At this time, the third cylinder 801 drives the moving block 802 to move, so that the hot cutting blade 805 separates the adhesive film from the panel. When the hot cutting blade 805 moves to the lower center of the assembly 701, the second cylinder 702 on the left side of the assembly 701 rises, and simultaneously the second cylinder 702 on the right side drives the pressure plate 703 to descend. After the fixing plate 6 continues to fix the photovoltaic panel, the hot cutting blade 805 continues to move, completing the separation step of the entire adhesive film on the surface of the photovoltaic panel. After the separation is completed, the feeding mechanism is used to... After the photovoltaic panel is conveyed by component 5 to the guide roller 3 on the right side of the frame 1, the mounting frame 904 below is lowered by the first cylinder 903. At the same time, the limiting rod 15 above the mounting frame 904 slides within the mounting plate 902, so that the multiple sets of vacuum suction cups 905 on both sides of the mounting frame 904 come into contact with the adhesive film separated from the surface of the photovoltaic panel. The adhesive film is then adsorbed by the vacuum suction cups 905. The power source for the vacuum suction cups 905 is provided externally. After the adhesive film is adsorbed, the first cylinder 903 drives the mounting frame 904 to rise. During this process, the synchronous motor drives the rotating rod 12 to rotate, and the rotating rod 12 simultaneously drives the second tooth. The first gear 14 rotates synchronously with the second gear 13, causing the first gear 14 to rotate, which in turn causes the rotating shaft 901 to rotate. This causes the rotating shaft 901 to rotate the mounting plate 902, rotating the mounting bracket 904 on the other side above the frame 1. The mounting bracket 904 that adsorbs the adhesive film moves to the outside of the frame 1 and can be released by the vacuum suction cup 905 to release the adhesive film for collection. The photovoltaic panel that has separated the adhesive film is then transported to subsequent equipment for processing via the guide roller 3, thus completing a series of tasks.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
