Description

Technical Field

[0001] This invention relates to the field of flipping equipment, and in particular to an automatic flipping and packaging device for photovoltaic modules. Background Technology

[0002] As the proportion of large-size photovoltaic modules continues to increase, existing traditional packaging methods cannot meet the packaging and transportation needs. Due to the limitations of the panel size, the limitations of fully automatic packaging lines are becoming increasingly prominent. Semi-automatic packaging, with its flexibility, small footprint, and strong compatibility, is gradually becoming popular in various photovoltaic factories.

[0003] The current flipping equipment uses cylinder power to propel the flipping. When flipping to the 45° position, the cylinder flipping speed is too fast, causing the bottom component to shift before the other components. After the other components flip, they squeeze the last space, causing the last component to bulge, resulting in flipping failure, increased rework costs, and a serious reduction in packaging efficiency. Moreover, with the release of 210 and other specification components, the single pallet weight reaches 1180Kg, which places high technical requirements on the flipping torque.

[0004] In summary, how to effectively solve the problem of misalignment of the last component in a cylinder-type tilting machine is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic flipping and packaging device for photovoltaic modules, which can reduce the flipping speed and effectively solve the problem of misalignment during flipping.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0017] The automatic photovoltaic module flipping and packaging device provided by this invention includes a main power component, a first driven power component, and a second driven power component. The main power component has an adjustable rotational speed and a first rotational speed and a second rotational speed, where the first rotational speed is greater than the second rotational speed. When the photovoltaic module enters the transfer range, the rotational speed of the main power component switches from the first rotational speed to the second rotational speed. The first driven power component includes a first transmission part and a second transmission part, which are connected to the main power component.

[0033] In one specific embodiment, the photovoltaic module automatic flipping packaging device provided by the present invention is used to transfer photovoltaic modules from a turnover pallet 8 to a packaging pallet 9. It includes a main drive component, a first driven drive component, and a second driven drive component. The first driven drive component includes a first transmission part and a second transmission part. The main drive component and the first transmission part are connected in a transmission manner. The second driven drive component and the second transmission part are connected in a transmission manner to achieve a rotational speed of the second driven drive component that is different from that of the main drive component. The main drive component has a first rotational speed and a second rotational speed. When the photovoltaic module enters the transfer range, the rotational speed of the main drive component switches from the first rotational speed to the second conversion speed. The first rotational speed is greater than the second rotational speed. The second driven drive component is provided with at least two sets of fixers 2, wherein at least two sets of fixers 2 are perpendicular to each other. The fixers 2 are used to fix the turnover pallet 8 or the packaging pallet 9.

[0034] In the above structure, the photovoltaic module automatic flipping and packaging device includes a main power component, a first slave power component, and a second slave power component.

[0035] The rotational speed of the main power unit is adjustable. The main power unit has a first rotational speed and a second rotational speed, with the first rotational speed being greater than the second. When the photovoltaic module enters the transfer range, the rotational speed of the main power unit switches from the first rotational speed to the second conversion speed. The specific magnitudes of the first and second rotational speeds depend on factors such as the power output of the main power unit, the size and weight of the photovoltaic module, etc.

[0036] The first power assembly includes a first transmission section and a second transmission section. The main power assembly and the first transmission section are connected by a transmission. The main power assembly provides power to drive the first transmission section to move.

[0037] The second power component and the second transmission unit are connected by a transmission. The second transmission unit drives the second power component to operate, so that the second power component can obtain a rotational speed different from that of the main transmission component.

[0038] The second power unit serves as the load-bearing carrier for the photovoltaic module. At least two sets of fixtures 2 are installed on the second power unit, and the at least two sets of fixtures 2 are perpendicular to each other. The fixtures 2 are used to fix the turnover pallet 8 or the packaging pallet 9. In the initial state, at least one set of fixtures 2 is in the horizontal direction to fix the turnover pallet 8, and at least one set of fixtures 2 is in the vertical direction to fix the packaging pallet 9.

[0039] Initially, the photovoltaic modules are placed on the turnover pallet 8, which is a self-contained pallet. The automatic photovoltaic module flipping and packaging device is used to transfer the photovoltaic modules from the turnover pallet 8 to the packaging pallet 9, which is a pre-placed pallet in a vertical position. It should be noted that the packaging pallet 9 is initially fixed in a horizontal position, and after the second drive unit rotates 90°, the packaging pallet 9 is in a vertical position.

[0040] In the automatic photovoltaic module flipping and packaging device, during the transfer of photovoltaic modules from the turnover pallet 8 to the packaging pallet 9, when the photovoltaic module enters the transfer range, the rotation speed of the main propulsion component switches from a first rotation speed to a second conversion speed. Specifically, when the photovoltaic module is not in the transfer range, the main propulsion component rotates at the first rotation speed; when the photovoltaic module is in the transfer range, the main propulsion component rotates at the second rotation speed, and the speed change occurs at the flipping critical node.

[0041] In this embodiment, the specific operation method includes: placing the horizontally placed pallet assembly into the inner area of ​​the second driven power assembly using a forklift, and withdrawing the forklift after reaching the limit area; after activating the control box switch, the retainer 2 advances to clamp and fix the turnover pallet 8; the main power assembly is activated, driving the first driven power assembly to move, and the first driven power assembly transmits power to the second driven power assembly outside the second driven power assembly, driving the second driven power assembly to rotate; when it rotates to the junction angle, the main power assembly reduces the transmission speed according to the program setting to ensure that the assembly is stably transferred between the two pallets; after the transfer is completed, the rotation is accelerated until the assembly is placed vertically on the packaging pallet 9, the equipment stops working, and the forklift is used to remove the flipped assembly, completing the flipping operation.

[0042] The automatic photovoltaic module flipping and packaging device provided by this invention utilizes existing flipping equipment, reduces the flipping speed, and can effectively solve the problem of misalignment of the last module in a cylinder-type flipping machine; it has a high packaging yield, high packaging efficiency, and reduced costs.

[0043] Based on the above specific embodiments, the power component is a servo motor 4, the first power component is a gear set, the gear set includes an input gear 5 and an output gear 6, the first transmission part is specifically the input gear 5, the second transmission part is specifically the output gear 6, and the second power component is a roller 1 with a gear rack 7 fixed on its outer wall. The input gear 5 meshes with the output shaft gear of the servo motor 4, the output gear 6 is coaxially connected with the input gear 5, and the output gear 6 meshes with the gear rack 7.

[0044] In practical applications, the power component is a servo motor 4, and the output shaft of the servo motor 4 has an output shaft gear. The first power component is a gear set, which includes an input gear 5 and an output gear 6. The input gear 5 of the gear set meshes with the output shaft gear of the servo motor 4. The servo motor 4 provides power to drive the output shaft gear to rotate, thereby driving the input gear 5 of the gear set to rotate. The output gear 6 is coaxially connected to the input gear 5, and the input gear 5 and the output gear 6 move coaxially, with the output gear 6 following the rotation of the input gear 5.

[0045] The second power component is roller 1, with a gear rack 7 fixed to its outer wall. The gear rack 7 meshes with the output gear 6 of the gear set. The output gear 6 of the gear set drives the gear rack 7 to rotate, thereby driving roller 1 to rotate. Roller 1 rotates through gear meshing, which is simple in structure and stable in transmission. The servo motor 4 has high power and is easy to control. According to the program setting, it rotates at the critical node of flipping to ensure that the components transferred between the pallets can be received stably and safely.

[0046] Based on the above specific embodiments, the number of fixtures 2 is two sets, which is simple in structure and easy to install. The servo motor 4 alternates between forward and reverse rotation, and the two pallet placement positions of the turnover pallet 8 and the packaging pallet 9 are alternately changed. At all times, one pallet placement position is in the horizontal direction and the other placement position is in the vertical direction. After one flipping process is completed, the pallet placement position of the turnover pallet 8 does not need to be reset. The two pallet placement positions work in forward and reverse cycles, which improves work efficiency.

[0047] Of course, the number of fixtures 2 can also be four sets. The four sets of fixtures 2 are installed on the four sides of the roller 1 to form a rectangular structure. At this time, the servo motor 4 can rotate in one direction. The four pallet placement positions are installed with turnover pallets 8 and packaging pallets 9 in sequence to realize dynamic rotation cycle.

[0048] Based on the above specific embodiments, the transfer range is α1-α2, where α1 is less than 45° and α2 is greater than 45°.

[0049] When photovoltaic modules are transferred from turnover pallet 8 to packaging pallet 9, the force transmission occurs around a 45° angle. Therefore, controlling the rotation speed at around 45° is the most critical step.

[0050] In this embodiment, the rotational angular velocity program has been pre-written into the internal coding program of the power component, and the entire rotation process can be divided into three stages:

[0051] Start-up phase: Start-up speed 0.1π / S, time 2S, rotate the component to a 36° angle.

[0052] Transfer phase: After rotating to 36°, the coding program controls the rotational angular velocity to decrease to 0.05π / S, taking 2S to rotate to 54°. During this process, the component gradually moves away from the turnover pallet 8 and moves closer to the packaging pallet 9 to receive force, completing the transfer of pallet force.

[0053] Final stage: After rotating to 54°, restore the rotational angular velocity to 0.1π / S, taking 2 seconds to rotate to 90°, completing the overall flipping operation.

[0054] Based on the above specific embodiments, the fixture 2 includes at least two telescopic cylinders and a push rod. The at least two telescopic cylinders are fixed to the inner wall of the roller 1, and the push rod is installed at the movable end of the telescopic cylinders. The push rod can press against the side walls of the turnover pallet 8 and the packaging pallet 9, pushing and fixing the pallets to a designated position, thereby fixing the turnover pallet 8 and the packaging pallet 9 in the pallet placement position and ensuring that the pallets will not move arbitrarily and damage the components during the rotation of the roller 1. Simultaneously, the extension distance of the movable end of the telescopic cylinder is adjustable, allowing for the fixing of pallets of different sizes, improving the compatibility of the automatic packaging line, and making it suitable for products of different specifications. With a wide range of product specifications and good versatility, cost-saving packaging materials can be released in a timely manner.

[0055] Based on the above specific embodiments, the second power component is a cylindrical body with an internal accommodating space to accommodate the photovoltaic module. Preferably, the second power component is a hollow thin-walled cylinder with a larger accommodating space, reducing the weight of the roller 1 and making it easier to drive the roller 1 to rotate.

[0056] Based on the above specific embodiments, there are two gear racks 7, with a gap between them. The two gear racks 7 are evenly and symmetrically distributed, resulting in uniform force distribution, less damage to the teeth, and better rotational stability.

[0057] Optionally, the gear rack 7 is detachably connected to the roller 1. When the teeth of one gear rack 7 are damaged, the gear rack 7 can be removed from the roller 1 and replaced individually, reducing costs.

[0058] Based on the above specific embodiments, a support gear 3 for supporting the roller 1 is also included. Both the support gear 3 and the output gear 6 mesh with the gear rack 7, and the radius of the input gear 5 is larger than the radius of the output shaft gear.

[0059] In the above structure, the automatic flipping and packaging device for photovoltaic modules includes a support gear 3, an output gear 6 and a support gear 3, both located below the roller 1. The output gear 6 and the support gear 3 are located on both sides of the vertical axis of the roller 1, and the output gear 6 and the support gear 3 together support the roller 1.

[0060] Both the output gear 6 and the support gear 3 mesh with the gear rack 7 to ensure smooth rotation of the roller 1 and maintain its stability.

[0061] The radius of the input gear 5 is larger than that of the output shaft gear. By making full use of the torque principle and the V=Rω theorem, and based on the coordinated operation of the gear set, the larger radius of the input gear 5 transforms the high-speed, low-torque output of the power component into low-speed, high-torque output, ensuring a safe, reliable, and efficient flipping effect.

[0062] Based on the above specific embodiments, the radius of the output gear 6 is smaller than the radius of the input gear 5, and the radius of the output gear 6 is smaller than the radius of the gear rack 7. The output gear 6 meshes with the gear rack 7, and the high-speed, low-torque output of the output gear 6 is once again converted into low-speed, high-torque output, further improving the flipping torque, which is suitable for flipping various ultra-large and ultra-heavy products.

[0063] Based on the above specific embodiments, the radius of the output gear 6 is equal to the radius of the support gear 3, and the support point height of the roller 1 is the same, making the rotation more stable and reliable.

[0064] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
