Description

Technical Field

[0001] This utility model relates to the field of renewable resource recycling, specifically to a device for dismantling photovoltaic module junction boxes. Background Technology

[0002] A photovoltaic (PV) module consists of glass, a first EVA layer, a silicon wafer, a second EVA layer, a backsheet, a fluorine film (some PV modules do not have a fluorine film), and a junction box. The first EVA layer bonds the glass to the silicon wafer, and the second EVA layer bonds the silicon wafer to the backsheet. Disassembling recycled PV modules can yield valuable materials such as precious metals, thus making the disassembly of PV modules valuable.

[0003] CN109092842A discloses a method for dismantling scrapped photovoltaic modules. This method includes steps such as dismantling the aluminum frame, dismantling the junction box, removing the fluorine film, removing the backsheet, separating the EVA adhesive layer and backsheet, separating the silicon wafer layer, solder ribbon, and glass, and separating the materials individually. Since the main focus is on recycling the glass, solder ribbon, and silicon wafers from the photovoltaic module, the aluminum frame and junction box must be removed before other parts can be processed.

[0004] Currently, junction boxes are removed manually. Since junction boxes are usually bonded to the back panel with strong adhesive, manual removal involves using a scraper to pry the junction box off the back panel. This method is not only labor-intensive and physically demanding, but also inefficient. Utility Model Content

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 6 As shown, the photovoltaic module junction box removal device of this utility model includes a frame 1, a bracket 2, a first drive mechanism, a support 3, a second drive mechanism, a lifting and heating mechanism, a lifting and scraping mechanism, and a clamping mechanism. The following is a detailed description of each part and the relationship between them.

[0041] The frame 1 consists of crossbeams, longitudinal beams, and columns. The crossbeams are arranged transversely, the longitudinal beams are arranged longitudinally, and the columns are arranged vertically. A first slide rail 1a is provided on the frame 1 transversely, and the support 2 is slidably engaged with the first slide rail 1a. The support 2 includes a support body 2a, a slide block 2b, and a second slide rail 2c. The support body 2a is fixed to the slide block 2b, the slide block 2b is slidably engaged with the first slide rail 1a, the slide block 2b is connected to a first drive mechanism, and the second slide rail 2c is arranged longitudinally along the frame 1.

[0042] The first drive mechanism drives the support 2 to move linearly along the transverse direction of the frame 1. The first drive mechanism is connected to the support 2. The first drive mechanism includes a first motor 4 and a belt drive mechanism 5. The output end of the first motor 4 is connected to the belt drive mechanism 5. The belt drive mechanism 5 is arranged transversely along the frame 1 and is mounted on the frame 1. The belt drive mechanism 5 includes a driving pulley, a belt, a driven pulley, and a shaft. The shaft is mounted at both ends of the frame 1. The driving pulley and the driven pulley are connected to the shaft at both ends of the frame 1. The belt cooperates with the driving pulley and the driven pulley. The first motor 4 is connected to the shaft supporting the driving pulley. The first motor 4 is preferably a geared motor, which is preferably fixed on the frame 1. The belt in the belt drive mechanism 5 is connected to the slide 2b, which is L-shaped. In this embodiment, the belt drive mechanism 5 is located on the outside of the frame 1. To prevent the belt drive mechanism 5 from being damaged by collisions, a protective cover 1b is also included. The protective cover 1b covers the belt drive mechanism 5 and is fixed to the frame 1.

[0043] The support 3 and the bracket 2 are slidably engaged. In this embodiment, the bracket body 2a consists of two longitudinal support components and an end plate. After the longitudinal support components are arranged along the longitudinal direction of the frame 1, a clearance space is formed between the two longitudinal support components. The two ends of the longitudinal support components are fixed to the end plate, and the end plate is fixed to the slide 2b. The second slide rail 2c is installed on the longitudinal support components. The support 3 and the second slide rail 2c are slidably engaged. The support 3 spans between the two longitudinal support components and corresponds to the clearance space.

[0044] The second drive mechanism drives the support 3 to move linearly along the longitudinal direction of the frame 1. The second drive mechanism is mounted on the bracket 2. The second drive mechanism includes a second motor 6 and a lead screw 7. The second motor 6 is preferably a geared motor. The second motor 6 is fixed on the bracket 2 and mounted on the bracket body 2a. The torque output end of the second motor 6 is connected to one end of the lead screw 7. The other end of the lead screw 7 is rotatably engaged with the bracket 2. That is, there is a mounting hole on the end plate in the bracket 2, and a bearing is installed on the other end of the lead screw 7. The bearing engages with the mounting plate on the end plate, so that the lead screw 7 and the bracket 2 form a rotatable engagement. The lead screw 7 is threadedly connected to the support 3. The lead screw 7 and the support 3 constitute a lead screw mechanism.

[0045] The lifting and heating mechanism heats the junction box B. The lifting and heating mechanism is mounted on the support 3 and is located in the clearance space between two longitudinal support components in the bracket body 2a. In this embodiment, the lifting and heating mechanism includes a first lifting driver 8 and a hot knife 9. The first lifting driver 8 is fixed to the support 3, and the hot knife 9 is connected to the power output end of the first lifting driver 8. The first lifting driver 8 can be a linear drive component such as a cylinder, hydraulic cylinder, or electric cylinder. The hot knife 9 is an electrically heated hot knife.

[0046] The lifting and shoveling mechanism shovels the heated junction box B. The lifting and shoveling mechanism is mounted on the support 3. The mechanism includes a second lifting driver 10, an intermediate connecting component 11, and a shovel 12. The second lifting driver 10 is mounted on the support 3, and its power output end is connected to the intermediate connecting component 11. The shovel 12 is fixed to the intermediate connecting component 11, and is tilted with one end higher than the other. The second lifting driver 10 can be a linear drive component such as a cylinder, hydraulic cylinder, or electric cylinder. The intermediate connecting component 11 can be a rod-shaped component; in this embodiment, a hollow rod is preferred for the intermediate connecting component 11.

[0047] The clamping mechanism clamps the photovoltaic module and is connected to the frame 1. The clamping mechanism is fixed on the longitudinal beam of the frame 1. There are four clamping mechanisms. Each clamping mechanism includes a mounting plate 13, a third lifting drive 14, and a support plate 15. The mounting plate 13 is fixed to the frame 1 and the longitudinal beam of the frame 1. The third lifting drive 14 is fixed to the mounting plate 13. The support plate 15 is fixed to the third lifting drive 14. The third lifting drive 14 drives the support plate 15 to move up and down along the height direction of the frame 1. The support plate 15 includes an L-shaped support body 15a. One end of the L-shaped support body 15a is bent to form a bent part 15b.

[0048] It also includes an industrial control computer 16, a vision sensor 17 for acquiring images of junction box B, and a distance sensor 18. The industrial control computer 16 is electrically connected to the first drive mechanism, the second drive mechanism, the lifting and heating mechanism, the lifting and shoveling mechanism, the clamping mechanism, the vision sensor 17, and the distance sensor 18. The vision sensor 17 and the distance sensor 18 are respectively mounted on the bracket 2.

[0049] In this embodiment, the industrial control computer 16 is an electrical control unit with a PLC as its core. Since the industrial control computer 16 is existing technology, it will not be described in detail here. The vision sensor 17 feeds back the acquired image of junction box B to the industrial control computer 16, which accurately determines the position of junction box B. The distance sensor 18 is used to detect the distance between junction box B and the distance sensor 18. The distance sensor 18 feeds back the detected distance to the industrial control computer 16, which calculates the distance between the lifting heating mechanism, the lifting shovel mechanism, and junction box B, thereby facilitating the precise descent of the lifting heating mechanism and the lifting shovel mechanism.

[0050] The working process of this utility model is as follows: the photovoltaic module A with junction box B is released onto the longitudinal beam on the frame 1 by the hoisting equipment. It is first supported by the longitudinal beam. The industrial control computer 16 controls the third lifting drive 14 to work. The third lifting drive 14 drives the support plate 15 to rise. Multiple support plates 15 clamp and lift the photovoltaic module A, so that the photovoltaic module A is separated from the longitudinal beam.

[0051] The industrial computer 16 controls the first motor 4 to work, and the first motor 4 transmits power to the belt drive mechanism 5. The belt drive mechanism 5 drives the bracket 2 to move along the first slide rail 1a. During this process, the vision sensor 17 detects the image of the junction box B and feeds back the collected image of the junction box B to the industrial computer 16. The industrial computer 16 accurately determines the position of the junction box B.

[0052] The industrial control computer 16 controls the first and second drive mechanisms to position the hot knife 9 on one side above the junction box B, for example, the left side. Based on the detection data from the ranging sensor 18, the industrial control computer 16 controls the first lifting driver 8 to lower the hot knife 9, positioning it on the left side of the junction box B. The industrial control computer 16 then controls the second motor 6 to rotate the lead screw 7, driving the support 3 to move linearly along the longitudinal direction of the frame 1, thus moving the hot knife 9 along the left side of the junction box B and heating the entire left side of the junction box B. The hot knife is then positioned on the right side of the junction box B, and the above process is repeated to heat the right side of the junction box B. When the hot knife is positioned on the front side of the junction box B, the industrial control computer 16 controls the first motor 4 to move the bracket 2 laterally along the frame 1, thus moving the hot knife 9 along the front side of the junction box B and heating the entire front side of the junction box B. Finally, the hot knife is positioned on the rear side of the junction box B, and the process of moving the bracket 2 laterally along the frame 1 is repeated to heat the rear side of the junction box B.

[0053] After the hot knife 9 heats all sides of the junction box, it resets. The industrial control computer 16 controls the first and second drive mechanisms. Based on the detection data from the distance sensor 18, the industrial control computer 16 controls the second lifting driver 10 to position the scraper 12 at the front of the junction box B. The industrial control computer 16 controls the second motor 6 to rotate the lead screw 7, which drives the support 3 to move linearly along the longitudinal direction of the frame 1, thereby scraping the junction box B and detaching it from the photovoltaic module A.
