[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0040] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of components, so it cannot be understood as a limitation to the present invention. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example and do not limit the protection scope of the present invention.

[0041] As Figure 1 shown, the solar photovoltaic module 30 includes a back plate 31, a junction box 32 and an aluminum alloy frame 33. Each solar photovoltaic module 30 has a junction box 32, and the junction box 32 is arranged on one side of the bottom of the back plate 31. The aluminum alloy frame 33 is arranged around the back plate 31 and is mainly formed by enclosing four aluminum alloy side strips. Each aluminum alloy side strip has a flange 331 protruding from the bottom of the back plate 31.

[0042] As Figure 2 shown, the junction box disassembling device 10 includes a first bracket 11, a first working platform 12 and two groups of junction box disassembling mechanisms 13.

[0043] Vertical rods 111 are arranged around the first bracket 11, and the vertical rods 111 are slightly higher than the upper surface of the solar photovoltaic module 30 placed on the first working platform 12. A relatively large range of placement errors is allowed during loading, and during disassembly, the part of the vertical rods 111 higher than the solar photovoltaic module 30 is used for limiting.

[0044] The first working platform 12 is arranged at the center of the top of the first bracket 11 through a first support frame 122. The first working platform 12 includes four stainless steel pipes, and the four stainless steel pipes are welded horizontally to form a cross-shaped structure. The first support frame 122 can support and limit the first working platform 12.

[0045] Furthermore, a first rubber pad 121 is preferably provided on the first working platform 12 for placing the solar photovoltaic module 30. The first rubber pad 121 has a certain thickness and plays a certain buffering role when placing the solar photovoltaic module 30.

[0046] The two groups of junction box disassembling mechanisms 13 are symmetrically arranged on both sides of the first working platform 12 along the length direction of the solar photovoltaic module 30. Each group of junction box disassembling mechanisms 13 includes a scraper 131, a linear driving device for the scraper and a receiving box 135.

[0047] The scrapers 131 are symmetrically arranged on both sides of the first working platform 12. The edge of the scraper 131 has a certain elasticity to ensure that the cutting edge fits the surface of the back plate 31 of the solar photovoltaic module. The maximum stroke of the scraper 131 shall not exceed the flange 331 of the aluminum alloy frame.

[0048] Each blade 131 can move linearly under the drive of the blade linear drive device and can contact the junction box 32.

[0049] The blade linear drive device includes a blade drive assembly, a first ejector rod 133, and a first guide tube 134.

[0050] There are two sets of the above-mentioned blade drive assemblies, both preferably being the first hydraulic cylinders 132. As an alternative, it can also be other drive mechanisms in the prior art such as a first pneumatic cylinder or a lead screw drive mechanism.

[0051] The two sets of first hydraulic cylinders 132 are symmetrically arranged on both sides of the first working platform 12.

[0052] The first ejector rod 133 is arranged at the front end of the first hydraulic cylinder 132. A nut is welded at a relatively low position in the middle of the first ejector rod 133, and the first ejector rod 133 is installed on the piston rod 235 of the first hydraulic cylinder 132 through this nut. The blade 131 is installed on the back side of the nut.

[0053] The first guide tubes 134 are symmetrically arranged on both sides of the first hydraulic cylinders 132. The first ejector rod 133 is fixedly connected to the first guide tubes 134 horizontally and perpendicularly. The first guide tubes 134 and the first ejector rod 133 are preferably welded by stainless steel square tubes; the first guide tubes 134 are inserted into the stainless steel tubes at the corresponding positions of the first support frame 122 and have a certain gap. The first guide tubes 134 can slide in the stainless steel tubes of the first support frame 122 to limit the movement direction of the first ejector rod 133 and ensure that the first ejector rod 133 itself remains horizontal and stable in the height direction.

[0054] The material receiving box 135 is arranged on the first support 11 corresponding to the lower part of the blade 131 and can be disassembled along the length direction of the first support 11.

[0055] As Figure 3 As shown in the figure, the aluminum alloy frame disassembling device 20 includes a second support 21, a second working platform 22, and four groups of aluminum alloy frame disassembling mechanisms 23.

[0056] The second working platform 22 is arranged at the top center of the second support 21 through the second support frame 222. The second working platform 22 includes four stainless steel tubes, and the four stainless steel tubes are welded horizontally to form a cross-shaped structure. The second support frame 222 can support and limit the second working platform 22.

[0057] Furthermore, a rubber pad 221 with a certain thickness is preferably provided on the second working platform 22 to place the solar photovoltaic module 30, which can not only protect the solar photovoltaic module 30 from being rigidly damaged but also increase the friction force to prevent slipping after positioning, so as to smoothly remove the aluminum alloy frame 33.

[0058] Four sets of aluminum alloy frame disassembly mechanisms 23 are arranged around the second working platform 22. Each set of aluminum alloy frame disassembly mechanism 23 includes a second ejector rod 232, a second ejector rod linear drive device, and a material collection groove 234.

[0059] The second ejector rods 232 are arranged around the second working platform 22, preferably welded by stainless steel square tubes, and are respectively parallel to the four aluminum alloy side strips; each second ejector rod 232 can move linearly under the drive of the second ejector rod linear drive device and can contact the corresponding aluminum alloy side strip. The four second ejector rods 232 simultaneously press against the inner side of the aluminum alloy side strip and continue to extend outward to disassemble the aluminum alloy side strip from the back plate 31.

[0060] The second ejector rod linear drive device includes a drive cylinder or a lead screw drive mechanism two driven by a drive cylinder, and a second guide tube 233.

[0061] The outer side of the output end of the drive cylinder is provided with a second ejector rod 232. Among them, the drive cylinder is preferably a second hydraulic cylinder 231 or a second pneumatic cylinder.

[0062] The second guide tubes 233 are symmetrically arranged on both sides of the corresponding drive cylinder, perpendicular to the second ejector rods 232. A nut is welded at a slightly lower position in the middle and is installed on the piston rod 235 of the drive cylinder or the lead screw drive mechanism two through this nut. The second guide tubes 233 are inserted into the square tubes at the corresponding positions of the second support frame 222 and have a certain gap. The second guide tubes 233 can slide in the square tubes of the second support frame 222 to limit the movement direction of the second ejector rods 232 and ensure that the second ejector rods 232 themselves remain horizontal and stable in the height direction.

[0063] There are four sets of material collection grooves 234, which are respectively arranged around the outer side of the second working platform 22; each set of material collection grooves 234 includes two parallel U-shaped grooves. The outer side of the U-shaped groove is slightly higher than the solar photovoltaic module 30 placed on the second working platform 22, and the inner side of the U-shaped groove is slightly lower than the solar photovoltaic module 30 placed on the second working platform 22, which can limit the solar photovoltaic module 30 and can recycle the corresponding disassembled aluminum alloy side strips. This groove has a certain depth and can accommodate multiple aluminum alloy strips.

[0064] An automatic disassembly method for a solar photovoltaic module includes the following steps.

[0065] Step 1: Disassemble the junction box 32. The specific disassembly method includes the following steps.

[0066] Step 11. Place the solar photovoltaic module: The suction cup type robotic arm 1 uses the suction cup to place the solar photovoltaic module 30 to be disassembled on the rubber pad 121 of the working platform 12 of the junction box disassembling device 10 under the control of instructions, with the junction box 32 facing downwards. Then release the suction cup and return to the material pile to pick up the second solar photovoltaic module 30 for subsequent feeding. In this embodiment, since the edge of the shovel 131 has a certain elasticity, the solar photovoltaic module 30 can flatten the slightly higher part of the shovel 131 by its own weight, thus ensuring that the cutting edge fits the surface of the backplane 31 of the solar photovoltaic module.

[0067] Step 12. Position the solar photovoltaic module 30: When the linear drive device of the shovel is not started, the piston rod 235 is in the shortest initial position. Start the linear drive device of the shovel, and both shovels 131 move linearly synchronously under the drive of the linear drive device of the shovel. One of the shovels 131 contacts the junction box 32 and drives the solar photovoltaic module 30 to move outward; until one side of the solar photovoltaic module 30 adjacent to the junction box 32 contacts the vertical rod 111, the vertical rod 111 blocks the solar photovoltaic module 30 and positions the solar photovoltaic module 30; when one shovel 131 contacts the junction box 32, the other shovel can stop or be set to stop at the maximum stroke to prevent the other shovel from colliding with the flange 331 of the aluminum alloy frame 33.

[0068] Step 13. Disassemble the junction box 32: The shovel 131 in contact with the junction box 32 continues to move outward under the drive of the linear drive device of the shovel, thereby disassembling the junction box 32 from the backplane 31 of the solar photovoltaic module 30. The disassembled junction box 32 falls into the lower material receiving box 135, and the shovel 131 resets.

[0069] Step 2. Disassemble the aluminum alloy frame 33. The specific disassembly method includes the following steps.

[0070] Step 21. Place the solar photovoltaic module 30: Preferably, use the suction cup type robotic arm 2 to place the solar photovoltaic module 30 after the junction box 32 is removed on the rubber pad 221 of the working platform 22 of the aluminum alloy frame disassembling device 20 and release the suction cup. Then return above the junction box disassembling device 10 to prepare for transporting the second solar photovoltaic module 30. The flange 331 of the aluminum alloy frame 33 in the solar photovoltaic module 30 faces downwards, allowing a relatively large range of placement errors.

[0071] Step 22. Positioning of the solar photovoltaic module 30: Activate the linear drive device of the second ejector rod 232. The four second ejector rods 232 all move linearly synchronously under the drive of the corresponding linear drive device of the second ejector rod. If the solar photovoltaic module 30 is not in the central position, one side of the symmetrically arranged second ejector rods 232 will contact the flange 331 of the aluminum alloy frame 33 first, which will push the solar photovoltaic module 30 to move outward, thus achieving the alignment of the solar photovoltaic module 30. When each second ejector rod 232 contacts the flange 331 of the corresponding aluminum alloy frame 33, the positioning of the solar photovoltaic module 30 is achieved. At this time, the suction cup manipulator three presses down to assist in fixing the solar photovoltaic module 30.

[0072] Step 23. Disassembling the aluminum alloy frame 33: The four second ejector rods 232 all continue to move linearly synchronously under the drive of the corresponding linear drive device of the second ejector rod. The aluminum alloy frame 33 separates at the weakest end. The remaining aluminum alloy frame 33 only has the strength connected to the backplane 31. Under the auxiliary pressure of the suction cup manipulator three, the other side of the aluminum alloy frame 33 is pushed away from the backplane 31, so as to disassemble the four aluminum alloy side strips of the aluminum alloy frame 33 from the backplane 31 of the solar photovoltaic module 30. The disassembled aluminum alloy side strips fall into the lower material receiving groove 234. The second ejector rod 232 resets. The suction cup manipulator three removes the solar photovoltaic module 30 after the aluminum alloy frame 33 is removed from the working platform two 22 and places it on the conveyor belt or the designated position, and then returns above the aluminum alloy disassembling device to prepare for handling the next solar photovoltaic module 30; one disassembly is completed. After repeating the disassembly several times, the aluminum alloy side strips falling into the material receiving groove 234 are grabbed by the material receiving manipulator and moved to the conveyor belt or the designated location.

[0073] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
