Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to an auxiliary device and frame removal equipment for photovoltaic panel recycling and dismantling. Background Technology

[0002] A photovoltaic (PV) module is a power generation device that uses semiconductor materials (such as silicon) to convert light energy into direct current (DC). Its core principle is based on the photovoltaic effect, achieving stable power generation through a solid-state structure with no moving parts. It is suitable for powering small electronic devices, building surface integration, and grid-connected power systems. The module mainly consists of a laminate, an aluminum alloy frame, and a junction box. The laminate includes tempered glass, EVA film, silicon-based solar cells, and a backsheet, achieving both light transmission protection and photoelectric conversion.

[0003] After a period of use, the performance of photovoltaic panels will gradually decline, necessitating the replacement of unsuitable panels and the dismantling and recycling of their components. In existing technology, a photovoltaic panel dismantling machine is typically used to disassemble the aluminum alloy frame. The dismantling steps are as follows:

[0004] First, place the photovoltaic panel with the sun-facing side facing up on the workbench, and use the workbench to support the middle of the bottom of the photovoltaic panel;

[0005] Then, the lifting assembly drives the pressure plate to descend, and the lower pressure plate holds the photovoltaic panel against the middle of the top surface of the photovoltaic panel to clamp and fix the photovoltaic panel.

[0006] Finally, the push bar is pushed close to a support bar on the frame by telescopic components (such as electric telescopic rods, hydraulic cylinders, etc.), and the support bar is pushed from the inside of the photovoltaic panel outward until the support bar falls off.

[0007] However, usually only the fixed edge of the support strip is bonded to the edge of the photovoltaic panel. When the middle or bottom of the support strip is squeezed and pushed, the edge of the photovoltaic panel may bend upward and deform. The probability of the glass on the photovoltaic panel being damaged due to excessive bending is relatively high. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide an auxiliary device and frame dismantling equipment for the recycling and dismantling of photovoltaic panels, so as to solve the problem that when the support bar is squeezed and pushed in the middle or bottom of the existing technology, the edge of the photovoltaic panel bends upward and deforms, and the glass on the photovoltaic panel is more likely to be damaged due to excessive bending.

[0009] This utility model is achieved through the following technical solution:

[0010] An auxiliary device for recycling and dismantling photovoltaic panels includes a push bar parallel to the support bar to be dismantled. A limiting strip is provided on the side of the push bar facing the support bar. One end of the limiting strip is connected to the push bar, and the other end extends around the support bar to the top of the photovoltaic panel, with its end face coplanar with the light-facing surface of the photovoltaic panel.

[0011] Furthermore, the limiting strip is connected to a slide bar perpendicular to the push bar at one end facing the push bar, and the slide bar and the push bar are slidably connected along the length direction of the slide bar.

[0012] Furthermore, one end of the limiting strip is rotatably connected to the push bar, and the rotation center line is parallel to the push bar;

[0013] The limiting strip and the sliding strip are connected by a linkage assembly.

[0014] Furthermore, the linkage component includes a rack parallel to the slide bar and a gear meshing with the rack, wherein the rack is fixedly connected to the slide bar;

[0015] The gear is fixedly connected to the end of the limiting strip facing the push bar, and the gear and the push bar are rotatably connected about the axis of the gear.

[0016] Furthermore, a sliding hole adapted to the shape of the slide bar is formed on the surface plane along the length direction of the slide bar on the push bar, and one end of the slide bar is inserted into the sliding hole and slides along the length direction of the slide bar;

[0017] The bottom wall of the sliding hole facing away from the support bar has a notch, and the two ends of the gear are respectively inserted into the two side walls of the notch along the length direction of the push bar, and are rotated together.

[0018] The limiting strip can be rotatably embedded into the notch and abut against the top wall of the sliding hole.

[0019] Furthermore, the limiting strip is C-shaped, and the width of the support strip is smaller than the opening size of the limiting strip.

[0020] Furthermore, multiple limiting strips are provided and are evenly arranged along the length direction of the pusher strip;

[0021] The ends of the multiple limiting strips facing away from the push strip are connected to a common pressure strip.

[0022] A frame dismantling device includes the above-mentioned auxiliary device for recycling and dismantling photovoltaic panels and a workbench. The workbench has a boss for supporting the photovoltaic panels on its surface, and a first telescopic rod that extends and retracts in the horizontal direction is fixedly installed on the side of the boss.

[0023] The movable end of the first telescopic rod is fixedly connected to the push bar, and the telescopic direction of the first telescopic rod is perpendicular to the push bar;

[0024] A second telescopic rod is provided above the boss. The second telescopic rod is fixedly installed on the workbench by a bracket. The output end of the second telescopic rod is fixedly connected to a pressure plate.

[0025] The beneficial effects of this utility model are as follows:

[0026] This auxiliary device and frame-removing equipment for photovoltaic panel recycling and dismantling uses a limiting strip on the push bar. One end of the limiting strip extends past the support strip to the top edge of the photovoltaic panel, forming a limiting point above the edge of the photovoltaic panel. When the push bar presses and pushes the middle or bottom of the support strip, the end of the support strip corresponding to the edge of the photovoltaic panel abuts against the end of the limiting strip facing away from the push bar. This can limit the upward bending deformation of the photovoltaic panel edge and reduce the probability of damage to the glass on the photovoltaic panel due to excessive bending.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0044] Please see Figure 1-10 This utility model provides a technical solution: an auxiliary device for recycling and dismantling a photovoltaic panel 11, including a pusher 2 parallel to the support bar 12 to be dismantled. A limiting bar 3 is provided on the side of the pusher 2 facing the support bar 12. One end of the limiting bar 3 is connected to the pusher 2, and the other end extends around the support bar 12 to the top of the photovoltaic panel 11, and the end face is coplanar with the light-facing surface of the photovoltaic panel 11.

[0045] In this solution, by setting a limiting strip 3 on the pusher 2 and extending one end of the limiting strip 3 around the support strip 12 to the edge of the photovoltaic panel 11, a limiting point is formed above the edge of the photovoltaic panel 11. When the pusher 2 pushes the middle or bottom of the support strip 12, the support strip 12 corresponding to the edge of the photovoltaic panel 11 abuts against the end of the limiting strip 3 facing away from the pusher 2, which can limit the upward bending deformation of the edge of the photovoltaic panel 11 and reduce the probability of damage to the glass on the photovoltaic panel 11 due to excessive bending.

[0046] The limiting strip 3 is C-shaped, allowing the support strip 12 to be embedded in the opening of the limiting strip 3. The width of the support strip 12 is less than the opening depth of the limiting strip 3. When the limiting strip 3 moves with the push strip 2 to approach or move away from the support strip 12, the end of the limiting strip 3 facing away from the push strip 2 is always located above the photovoltaic panel 11, thus limiting the photovoltaic panel 11.

[0047] The limiting strip 3 and the push strip 2 can be detachably fixed or slidably connected along the width direction of the push strip 2.

[0048] Detachable fixed connection: By opening an insertion hole on the side of the push bar 2 facing the support bar 12, when in use, hold the limiting bar 3 to make the support bar 12 embed into the limiting bar 3, and then operate one end of the limiting bar 3 to fit tightly into the insertion hole, so that the limiting bar 3 moves together with the push bar 2, and the position of the limiting point can be adjusted synchronously with the push bar 2.

[0049] Sliding connection: By creating a groove along the width of the pusher bar 2 on the bottom surface of the pusher bar 2, one end of the limiting strip 3 is inserted into the groove and slidably engaged, allowing the relative position of the limiting strip 3 and the pusher bar 2 to be freely adjusted. For example, after the support strip 12 on the photovoltaic panel 11 has been disassembled, the limiting strip 3 can be manipulated to slide relative to the pusher bar 2, allowing the end of the limiting strip 3 facing away from the pusher bar 2 to slide off the photovoltaic panel 11, thus facilitating the removal of the photovoltaic panel 11.

[0050] Additionally, after the support bar 12 is squeezed by the push bar 2 to detach from the photovoltaic panel 11, the support bar 12 is thrown out. The limiting bar 3 is located on the movement trajectory of the support bar 12 to block it and limit the throwing distance, so as to facilitate storage.

[0051] In this embodiment: the limiting strip 3 is connected to a slide bar 4 perpendicular to the push bar 2 at one end facing the push bar 2, and the slide bar 4 and the push bar 2 are slidably connected along the length direction of the slide bar 4.

[0052] In this design, the slider 4 and the push bar 2 are located on the same horizontal plane. The limiting bar 3 can be fixedly connected to the slider 4. The slider 4 supports the limiting bar 3 and acts as a guide, so that the limiting bar 3 can slide smoothly relative to the push bar 2.

[0053] In this embodiment: one end of the limiting strip 3 is rotatably connected to the push strip 2, and the rotation center line is parallel to the push strip 2;

[0054] The limiting strip 3 and the slide bar 4 are connected by a linkage assembly.

[0055] In this scheme, when the slider 4 slides on the push bar 2, the linkage component can drive the limit bar 3 to rotate on the push bar 2.

[0056] Initially, under the action of gravity, the limiting strip 3 rotates to below the push strip 2, and the end of the slide strip 4 facing the support strip 12 extends beyond the support surface of the push strip 2. When the support strip 12 is disassembled, the external telescopic structure drives the push strip 2 to move closer to the target support strip 12. The slide strip 4 abuts against the support strip 12 before the push strip 2, and the protruding part of the slide strip 4 is retracted into the push strip 2. The limiting strip 3 is driven to rotate and rise through the linkage component. When the push strip 2 abuts against the support strip 12 (the protruding part of the slide strip 4 is completely retracted into the push strip 2), the end of the limiting strip 3 facing away from the push strip 2 rotates to above the photovoltaic panel 11 and abuts against the light-facing surface of the photovoltaic panel 11.

[0057] Therefore, during the process of the push bar 2 pressing and disassembling the support bar 12, the limiting bar 3 can automatically rotate and lift, and play a limiting role on the edge of the photovoltaic panel 11.

[0058] In this embodiment: the linkage component includes a rack 41 parallel to the slide bar 4 and a gear 31 meshing with the rack 41, and the rack 41 is fixedly connected to the slide bar 4;

[0059] The gear 31 is fixedly connected to the end of the limiting strip 3 facing the pusher 2, and the gear 31 and the pusher 2 are rotatably connected about the axis of the gear 31.

[0060] In this scheme, the power of the slide bar 4 sliding on the push bar 2 is transmitted to the limit bar 3 through the linkage assembly composed of rack 41 and gear 31. Through mechanical transmission, the limit bar 3 is driven to rotate and lift, making the device compact and highly stable.

[0061] In this embodiment: a sliding hole 21 adapted to the shape of the slide bar 4 is provided on the surface plane of the push bar 2 along the length direction of the slide bar 4. One end of the slide bar 4 is inserted into the sliding hole 21 and slides along the length direction of the slide bar 4.

[0062] The bottom wall of the sliding hole 21 facing away from the support bar 12 has a notch 22. The two ends of the gear 31 are respectively inserted into the two side walls of the notch 22 along the length of the push bar 2 and rotated together.

[0063] The limiting strip 3 can be rotatably embedded in the notch 22 and abut against the top wall of the sliding hole 21.

[0064] In this design, the slider 4 has a through hole that matches the thickness of the limiting strip 3. When the limiting strip 3 is embedded in the notch 22, it can pass through the through hole and abut against the top wall of the slider hole 21. The limiting strip 3 can be in the following two states on the pusher 2:

[0065] State 1, such as Figure 6 As shown, the limiting strip 3 abuts against the top wall of the sliding hole 21, the support strip 12 moves out from the opening of the limiting strip 3, and the limiting strip 3 is completely below the support strip 12. The push strip 2 can move freely on the horizontal plane with the external telescopic structure (the limiting strip 3 and the support strip 12 do not interfere), so as to facilitate the installation or removal of the photovoltaic panel 11.

[0066] State 2, such as Figure 5 As shown, the support bar 12 is embedded in the opening of the limiting bar 3. The end of the limiting bar 3 facing away from the push bar 2 abuts against the top surface (light-facing surface) of the photovoltaic panel 11. The end of the slider 4 facing the support bar 12 is flush with the abutting surface of the push bar 2. The slider 4 is difficult to continue sliding and lifting the limiting bar 3, which can reduce the probability of the photovoltaic panel 11 being squeezed and damaged by the limiting bar 3.

[0067] In state one, the length of the section of the slide bar 4 protruding beyond the abutting surface of the push bar 2 is equal to the arc length corresponding to the rotation angle of the gear 31 in state two. Therefore, by adjusting the length of the slide bar 4 protruding in state one, the end face of the limiting bar 3 facing away from the push bar 2 in state two can be made coplanar (abutting) with the light-facing surface of the photovoltaic panel 11, thus providing a limiting protection function for the photovoltaic panel 11.

[0068] In this embodiment: the limiting strip 3 is C-shaped, and the width of the support strip 12 is smaller than the opening size of the limiting strip 3.

[0069] In this scheme, the straight-line distance from the rotation center line of the limiting strip 3 to the end of the limiting strip 3 facing away from the push strip 2 is defined as the opening length dimension.

[0070] In state two, the end of the limiting strip 3 facing away from the push strip 2 abuts against the light-facing surface of the photovoltaic panel 11. The contact point is located on the side of the rotation center line facing away from the support strip 12. The straight-line distance from the rotation center line to the top edge of the side of the support strip 12 facing away from the push strip 2 is less than the opening length, so that the limiting strip 3 can rotate smoothly to rise or fall.

[0071] During use, after the support bar 12 disengages from the photovoltaic panel 11, it moves towards the limiting bar 3 under inertia and falls onto the limiting bar 3, applying downward pressure to it. The limiting effect of the support bar 12 on the slider 4 disappears, and the limiting bar 3 automatically reverses and descends to reset, facilitating the installation and removal of new photovoltaic panels 11. Alternatively, relevant technicians can manually reverse and reset the limiting bar 3.

[0072] In this embodiment: multiple limiting strips 3 are provided and are evenly arranged along the length direction of the push strip 2;

[0073] The ends of the multiple limiting strips 3 facing away from the push strip 2 are connected to a pressing strip 32.

[0074] In this solution, a barrier net structure is formed by multiple limiting strips 3, which can store the disassembled support strips 12 inside the barrier net, reducing the risk of the support strips 12 being thrown and falling freely and causing harm to personnel or equipment.

[0075] Furthermore, multiple limiting strips 3 form multiple limiting points, providing multi-point support and limiting for the top edge of the photovoltaic panel 11, further reducing the probability of damage to the glass on the photovoltaic panel 11 due to excessive bending. The multiple limiting strips 3 are connected into a whole by the lower pressure strip 32, improving the overall structural strength of the device. Additionally, elastic materials such as rubber pads can be placed on the abutting surface of the lower pressure strip 32. These rubber pads contact the photovoltaic panel 11, providing a buffering effect and reducing the risk of damage to the photovoltaic panel 11 due to impact from rigid supports.

[0076] A frame dismantling device includes the above-mentioned auxiliary device for recycling and dismantling photovoltaic panels 11 and a workbench 51. The workbench 51 has a boss for supporting the photovoltaic panels 11 on its table surface, and a first telescopic rod 52 that extends and retracts in the horizontal direction is fixedly installed on the side of the boss.

[0077] The movable end of the first telescopic rod 52 is fixedly connected to the push bar 2, and the telescopic direction of the first telescopic rod 52 is perpendicular to the push bar 2;

[0078] A second telescopic rod 53 is provided above the boss. The second telescopic rod 53 is fixedly installed on the workbench 51 by a bracket 55. The output end of the second telescopic rod 53 is fixedly connected to a lower pressure plate 54.

[0079] In this design, the first telescopic rod 52 and the second telescopic rod 53 can be selected as electric push rods (such as Yongnuo YNT-04) or hydraulic cylinders (such as Changyuan Hydraulic HSG80×500-10MPa). The first telescopic rod 52 applies power to the push bar 2, causing it to move and press against the support bar 12, thus detaching it from the photovoltaic panel 11 and achieving the purpose of disassembling the frame of the photovoltaic panel 11. The second telescopic rod 53 drives the lower pressure plate 54 to rise and fall, causing the lower pressure plate 54 to abut against the photovoltaic panel 11.

[0080] The bracket 55 is U-shaped, and its two ends are fixedly connected to the two sides of the workbench 51 along the width direction. The inside is used to place and install the photovoltaic panel 11.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
