Description

Technical Field

[0001] The invention relates to the technical field of waste photovoltaic panel processing, and in particular to an automatic dismantling machine for waste photovoltaic panel edges. Background Art

[0002] With the promotion and application of green energy, the photovoltaic industry has developed rapidly. Photovoltaic panels, as core components in this field, are widely used in various occasions. However, as photovoltaic panels reach the end of their service life, how to efficiently and environmentally friendly deal with these discarded photovoltaic panels has become a major challenge facing the industry. The recycling and reuse of discarded photovoltaic panels is not only related to environmental protection, but also an important part of promoting resource recycling. Against this background, the photovoltaic panel edge automatic disassembly machine came into being. It is specially designed for the disassembly of the edge frame in the photovoltaic panel recycling process.

[0003] Although the existing photovoltaic panel edge automatic disassembly machine can realize the automated disassembly operation to a certain extent, it still has the following defects in actual use: 1. During disassembly operations, the battery cells are usually facing upwards and the edge frames are facing downwards. When the pressure plate moves down to fix the battery cells on the support table, the uneven pressure distribution will cause the middle of the battery cells to sink and the surrounding areas to warp up, which may cause glass fragments to fly into the air, increasing the safety risk of operators.

[0004] 2. During the disassembly process, the machine moves the push plates around to split the edge frame. However, the length of these push plates is usually fixed and cannot be adjusted according to the length of the edge frame. This means that the push plates can only exert force on the middle of the frame, while the edge of the frame lacks effective support. This can easily cause the frame to bend and deform during the disassembly process, or even incomplete separation between two adjacent frames, resulting in incomplete disassembly and unsatisfactory disassembly results. There is often residual glass debris on the disassembled frame, which needs to be further processed by a frame de-glassing machine before it can be recycled. However, due to the bending of the frame, it is difficult to directly remove the residual glass debris through the frame de-glassing machine. The frame needs to be straightened before processing the glass debris. The whole process is relatively complicated, affecting the recycling efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic dismantling machine for discarded photovoltaic panels that can adapt to photovoltaic panels of different specifications and effectively support the edge of the frame in order to solve the above-mentioned problem.

[0006] The present invention achieves the above-mentioned purpose through the following technical scheme: an automatic dismantling machine for the edges of discarded photovoltaic panels, comprising a frame, an inner bottom of the frame being connected to a support platform for supporting the photovoltaic panels, a hydraulic cylinder 1 being installed on the inner top of the frame, a piston rod of the hydraulic cylinder 1 being connected to an inverted U-shaped connecting plate, the bottom of the inverted U-shaped connecting plate being connected to an installation frame with an open top, a disassembly mechanism being provided on the installation frame, the disassembly mechanism comprising a movable plate, a sliding rod and a telescopic pushing frame, movable plates are slidably connected to the four sides of the inner bottom of the installation frame, sliding rods are slidably connected to the four movable plates, the sliding rods extend out of the installation frame and are connected to the telescopic pushing frames, the four telescopic pushing frames are distributed along the circumference of the installation frame, hydraulic cylinders 2 are installed on the four movable plates, the telescopic rods of the four hydraulic cylinders 2 are respectively connected to the four telescopic pushing frames, the inner top of the inverted U-shaped connecting plate and the inner bottom of the installation frame are provided with adjustment parts, and the adjustment parts are used to adjust the spacing between two symmetrical movable plates.

[0008] As a further optimization scheme of the present invention, an inclined surface is provided on the push block. When the push block moves back into the U-shaped push plate along with the push plate, the inclined surface on the push block is squeezed by the U-shaped push plate, so that the upper and lower push blocks approach each other and retract into the U-shaped push plate.

[0009] As a further optimization scheme of the present invention, the adjusting member includes a bidirectional screw rod rotatably connected to the top of the U-shaped push plate, and two nuts are threadedly connected to the bidirectional screw rod, and the two nuts are respectively connected to two push plates arranged on the same U-shaped push plate.

[0010] As a further optimization scheme of the present invention, the adjusting part includes a dual-axis motor and a screw. The dual-axis motor is installed on the inner top of the inverted U-shaped connecting plate and the inner bottom of the mounting frame. Screws are connected to the output shafts on both sides of the dual-axis motor. The screws are rotatably connected to the mounting frame, and the four screws are threadedly connected to the four movable plates respectively.

[0011] As a further optimization scheme of the present invention, two openings are symmetrically opened on the top of the support platform, and conveyor belts for conveying battery cells are provided in the two openings. The top of the conveyor belts is flush with the top of the support platform.

[0012] As a further optimization solution of the present invention, the outer surface of the conveyor belt is coated with an anti-slip coating to increase the friction with the battery cells.

[0013] As a further optimization solution of the present invention, receiving plates for receiving the frame are connected to the four sides of the inner bottom of the support platform.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention makes the battery cell face downward and the edge frame face upward, and makes the mounting frame and the telescopic push frame move downward into the edge frame, so that the four telescopic push frames are in contact with the inner walls of the four frames respectively, ensuring uniform pressure distribution and avoiding the middle of the battery cell sinking and the surrounding parts warping up when the battery cell is pressed down to be fixed, thereby reducing the risk of glass fragments flying into the air and improving safety.

[0015] 2. The four telescopic push racks of the present invention are adjustable in length, so that they can adapt to photovoltaic panels of different specifications, achieve effective support for the edge of the frame, avoid bending and deformation of the frame during the disassembly process, and can completely separate two adjacent frames, thereby improving the disassembly effect and ensuring thorough disassembly, thereby eliminating the need for subsequent straightening of the frame and improving the recycling efficiency.

[0016] 3. The disassembled battery cells can be transported to the next process through the conveyor belt, without the need to manually remove the battery cells from the support table, which significantly shortens the time for changing and unloading materials and improves the overall operation efficiency.

The two slide grooves 634 in each group are symmetrically arranged up and down. A slider 635 is slidably arranged in each slide groove 634. A push block 636 is connected to the side of the slider 635 facing away from the installation frame 5. Two adjacent push blocks 636 at the same height are in contact. The push block 636 is provided with an inclined surface 63 7. The side of the push block 636 facing away from the installation frame 5 is flush with the side of the U-shaped push plate 631 facing away from the installation frame 5. At least four connecting sleeves 630 are evenly spaced and connected on the side of the push plate 633 facing away from the installation frame 5. A guide rod 639 is connected in each connecting sleeve 630. A through hole 6310 that fits with the guide rod 639 is opened on each push block 636. Each guide rod 639 is sleeved with two upper and lower springs 638. The two ends of the spring 638 are respectively abutted against the connecting sleeve 630 and the push block 636. An adjusting member is provided at the top of the U-shaped push plate 631. The adjusting member is used to adjust the distance between the two push plates 633. The adjusting member includes a bidirectional screw rod 6311 rotatably connected to the top of the U-shaped push plate 631.

[0028] First, place the abandoned photovoltaic panel in the center on the support platform 2, and make the cells on the abandoned photovoltaic panel face downward and the edge frame face upward, and then adjust the positions of the four telescopic push frames 63 according to the specifications of the edge frame. Control the double-axis motor 65 on the inverted U-shaped connecting plate 4 to work, which can drive the screw rods 66 on the left and right sides to rotate, and the rotation of the screw rods 66 on the left and right sides drives the movable plates 61 on the left and right sides to move away from each other, thereby driving the telescopic push frames 63 on the left and right sides to move away from each other through the hydraulic cylinders 64 on the left and right sides to match the short sides of the frame. Similarly, control the double-axis motor 65 on the inverted U-shaped connecting plate 4 to drive the screw rods 66 on the left and right sides to reverse, which can drive the movable plates 61 on the left and right sides to move closer to each other, thereby driving the telescopic push frames 63 on the left and right sides to move closer to each other through the hydraulic cylinders 64 on the left and right sides. The double-axis motor 65 on the control installation frame 5 is operated to drive the screw rods 66 on the front and rear sides to rotate, and the screw rods 66 on the front and rear sides rotate to drive the movable plates 61 on the front and rear sides to move away from each other, thereby driving the telescopic push frames 63 on the front and rear sides to move away from each other until they match the long sides of the frame through the hydraulic cylinders 64 on the front and rear sides. Similarly, the double-axis motor 65 on the control installation frame 5 drives the screw rods 66 on the front and rear sides to reverse, which can drive the movable plates 61 on the front and rear sides to move closer to each other, thereby driving the telescopic push frames 63 on the front and rear sides to move closer to each other through the hydraulic cylinders 64 on the front and rear sides. In this way, the positions of the four telescopic push frames 63 of the device can be flexibly adjusted to adapt to photovoltaic panels of different specifications, ensuring the subsequent effective compression of the edge of the battery sheet, and then the telescopic push frames 63 are telescopically adjusted according to the specifications of the edge frame to make the lengths of the four telescopic push frames 63 match the edge frame. Then, the hydraulic cylinder 1 3 is controlled to drive the inverted U-shaped connecting plate 4 to drive the installation frame 5 to move downward to press the battery cell and fix it on the support platform 2, and the telescopic push frame 63 moves downward to enter the edge frame. The four telescopic push frames 63 contact the inner walls of the four frames respectively. Because the battery cell faces downward and the edge frame faces upward, and the four telescopic push frames 63 contact the inner walls of the four frames respectively, it can ensure that the pressure is evenly distributed, avoiding the middle of the battery cell sinking and the surroundings rising when pressing down to fix the battery cell, thereby reducing the risk of glass fragments splashing into the air and improving safety. Then, the four hydraulic cylinders 2 64 are controlled to work synchronously to drive the four telescopic push frames 63 to move outward synchronously to achieve the synchronous disassembly of the four frames of the edge frame. After the edge frame is disassembled, the hydraulic cylinder 2 64 is controlled to drive the telescopic push frame 63 to move inward and reset. Finally, the hydraulic cylinder 1 3 is controlled to drive the inverted U-shaped connecting plate 4 to drive the installation frame 5 to move upward and reset, and the telescopic push frame 63 moves upward and reset accordingly.

[0029] When it is necessary to extend the telescopic push frames 63 on the front and rear sides to adapt to edge frames of different lengths, the two-way screw rods 6311 on the front and rear sides can be manually rotated to make the two nuts 6312 thereon move away from each other, thereby making the left and right push plates 633 on the front and rear U-shaped push plates 631 move away from each other, and the push blocks 636 on the left and right push plates 633 move away from each other accordingly. When the push block 636 is stored in the U-shaped push plate 631, the spring 1 638 is compressed. When the push block 636 moves out of the U-shaped push plate 631 along with the push plate 633, the push blocks 636 on the upper and lower sides are pushed away from each other by the spring 1 638. After the upper push block 636 moves up, its top is flush with the top of the U-shaped push plate 631, and after the lower push block 636 moves down, its bottom is flush with the bottom of the U-shaped push plate 631, thereby ensuring that the push block 636 and the U-shaped push plate 631 are more closely matched, so that the frame is more evenly stressed during the disassembly process, and the entire disassembly process is more stable and reliable. Similarly, when it is necessary to shorten the telescopic push frame 63 on the front and rear sides, the two-way screw rods 6311 on the front and rear sides are manually reversed, so that the left and right push plates 633 on the front and rear sides of the U-shaped push plate 631 are close to each other, and the push blocks 636 on the left and right push plates 633 are close to each other accordingly. When the push block 636 moves back into the U-shaped push plate 631 along with the push plate 633, the inclined surface 637 on the push block 636 is squeezed by the U-shaped push plate 631, so that the push blocks 636 on the upper and lower sides are close to each other and retracted into the U-shaped push plate 631, and the spring 1 638 is compressed accordingly. When it is necessary to extend the telescopic push frame 63 on the left and right sides to adapt to edge frames of different widths, the two-way screw rods 6311 on the left and right sides are manually rotated, so that the front and rear push plates 633 on the left and right sides of the U-shaped push plate 631 are separated from each other, and the push blocks 636 on the front and rear push plates 633 are separated from each other accordingly, so as to achieve the elongation adjustment of the telescopic push frame 63 on the left and right sides. By reversing the two-way screw rods 6311 on the left and right sides, the front and rear push plates 633 on the left and right sides of the U-shaped push plate 631 are close to each other, and the push blocks 636 on the front and rear push plates 633 are close to each other accordingly, so as to achieve the shortening adjustment of the telescopic push frame 63 on the left and right sides. Because the length of the four telescopic push racks 63 is adjustable, they can adapt to photovoltaic panels of different specifications, achieve effective support for the edge of the frame, avoid bending and deformation of the frame during the disassembly process, and can completely separate two adjacent frames, thereby improving the disassembly effect and ensuring thorough disassembly, thereby eliminating the need for subsequent straightening of the frame and improving recycling efficiency.

[0030] See also Figure 8 Two openings 21 are symmetrically opened on the top of the support platform 2, and conveyor belts 7 for conveying battery cells are provided in the two openings 21. The top of the conveyor belt 7 is flush with the top of the support platform 2, and the outer surface of the conveyor belt 7 is coated with anti-slip paint to increase the friction with the battery cells, thereby ensuring that the battery cells can be stably and smoothly conveyed to the left.

[0031] After the mounting frame 5 moves upward and separates from the battery cell, the battery cell can be transported to the left to the next process by controlling the rotation of the conveyor belt 7. There is no need to manually remove the battery cell from the support table 2, which significantly shortens the material replacement and unloading time and improves the overall operation efficiency.

[0032] See also Figure 1 and Figure 8 A group of receiving plates 8 are connected to the left and right sides and the front and back sides of the inner side of the support platform 2. The receiving plates 8 are U-shaped. There are two receiving plates 8 in each group. The two receiving plates 8 in the left and right groups are symmetrically arranged front to back, and the two receiving plates 8 in the front and back groups are symmetrically arranged left to right. The U-shaped receiving plates 8 can receive the disassembled frames, realize the orderly collection of the frames, and facilitate the subsequent bundling of the frames.

It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
