[0002] Solar photovoltaic modules are generally composed of tempered glass, EVA film, battery layer, EVA film, and backplane stacked in sequence from bottom to top. The battery layer consists of several parallel battery strings and bus bars used to connect the welding strips of each battery string. In the production process of solar photovoltaic modules, the laminated parts (semi-finished photovoltaic modules after lamination) produced from the lamination process need to be transferred to the subsequent junction box installation process for the installation of the junction box. Since the surface of the semi-finished photovoltaic modules after lamination will inevitably carry static electricity, during the installation of the junction box, the diodes in the junction box are easily damaged by static electricity, affecting the product quality and service life of the solar photovoltaic modules. Therefore, in order to avoid the adverse effects of static electricity on photovoltaic modules, the industry usually uses static electricity brushes for destaticization.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to prevent the adverse effects of static electricity on photovoltaic modules, the prior art often performs anti-static treatment on photovoltaic modules.

[0028] For example, the Chinese utility model patent with publication number CN221829130U proposes a device for automatically removing static electricity from photovoltaic modules, including a bottom plate, a conveyor frame fixedly connected to the top of the bottom plate, a bracket arranged on the top of the conveyor frame, an adjustment plate fixedly connected to the inside of the bracket, both sides of the bottom of the adjustment plate are movably connected to fixed rods through a width adjustment mechanism, and the bottom of the fixed rod is movably connected to a conductive brush through a thickness adjustment mechanism. This patented technology uses an electrostatic brush to remove static electricity from the surface of the photovoltaic module, however, the electrostatic brush cannot effectively ensure that the static electricity on the entire surface of the module and the busbar is effectively removed, and there is also a risk of losing the module.

[0029] In addition, a study has proposed a "contactless" method for cleaning photovoltaic modules. This method uses electrostatic repulsion to make dust particles jump out of the surface of the module, charges the dust particles through metal rod-like electrodes, and then applies the charge to the solar cell module to repel the dust particles, causing them to jump into the air and away from the module. This method can not only effectively remove dust, but also reduce damage caused by static electricity, and improve the quality and service life of photovoltaic modules. However, the above-mentioned "contactless" method for cleaning photovoltaic modules is mainly aimed at clearing dust particles on the surface of photovoltaic modules. Although it can remove some static electricity on the surface of the module, this method is not suitable for promotion in photovoltaic module production lines. On the one hand, the equipment used in this method is complex and costly. On the other hand, its efficiency is low, which affects the production rhythm of photovoltaic modules. In addition, this method also has the defect of not being able to effectively remove static electricity on the busbar.

[0030] To this end, the embodiment of the present invention makes technological innovation based on the existing photovoltaic module production line. By adding a lifting cylinder and an electrostatic collection device, the static electricity on the surface of the photovoltaic module and the busbar can be effectively removed, and the impact on the quality of the photovoltaic module itself and the production efficiency can be effectively reduced.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 3As shown, an embodiment of the present invention provides a photovoltaic module production line static elimination device, which is arranged on a module transmission line and can be added to the production line of an existing photovoltaic module 7, or the existing production line can be transformed and upgraded. The device includes a lifting mechanism arranged in the module transmission line, which is used to lift the photovoltaic module 7 from the module transmission line, so that it is separated from the transmission line and supported above the lifting mechanism, so as to facilitate the static electricity removal operation; the lifting mechanism includes a component bearing platform 6 for bearing the photovoltaic module 7, and the bottom of the component bearing platform 6 is controlled by a plurality of lifting cylinders 11 to control its lifting; an electrostatic collection device 8 is suspended directly above the component bearing platform 6, and the electrostatic collection device 8 is suspended below a frame 5 through a plurality of suspension ropes 9, and the electrostatic collection device 8 is connected to a wire 13 for conducting static electricity; a position sensor 14 for identifying that the photovoltaic module 7 has arrived above the component bearing platform 6 is installed on the inner side of the frame 5; when the photovoltaic module 7 is transmitted to the top of the component bearing platform 6 via the component transmission line, the lifting mechanism moves upward to lift the photovoltaic module 7 to a preset height, at which time, the electrostatic collection device 8 is in full contact with the surface of the photovoltaic module 7, and the static electricity is conducted through the wire 13.

[0033] In a specific embodiment, the component transmission line is composed of two conveyor belts spaced apart from each other. Conveyor belt 1 and conveyor belt 2 are driven by a transmission motor 3, and realize circular transmission under the control of a control center 4, and stop at a designated position. It should be understood that the transmission motor 3 can be a servo motor to facilitate precise control of the position of the photovoltaic component 7.

[0034] In a specific embodiment, the frame 5 is composed of multiple steel sections to form a frame-shaped three-dimensional structure, four columns are fixed on the ground on both sides of the component transmission line, and the tops of the four columns are welded with crossbeams and longitudinal beams, wherein four suspension ropes 9 are fixed on the crossbeams / longitudinal beams on the two opposite sides through fixings, and the bottoms of the four suspension ropes 9 are connected to the electrostatic collection device 8. The fixings can be bolts, or other structural members that can be detachably connected, so as to adjust the length of the suspension ropes 9. The electrostatic collection device 8 has a flexible bottom surface that is in surface contact with the surface of the photovoltaic component 7, and is connected to the static electricity removal device through a wire 13. The flexible bottom surface of the electrostatic collection device 8 can adapt to the surface of the photovoltaic component 7. When the photovoltaic component 7 rises to a certain height, it contacts the flexible bottom surface and continues to rise. The flexible bottom surface can completely cover the photovoltaic component 7 to achieve full contact, including the busbars led out from the photovoltaic component 7 for installing the junction box. All are in contact with the flexible bottom surface of the electrostatic collection device 8 to achieve static electricity extraction.

[0035] In a specific embodiment, the lifting mechanism is composed of a component carrying platform 6 and a plurality of lifting cylinders 11 located at the bottom of the component carrying platform 6. The lifting cylinders 11 are preferably arranged in four numbers, which are respectively located at four corner positions below the component carrying platform 6. The four lifting cylinders 11 are respectively connected to the component carrying platform 6 through four telescopic support rods 12. The four lifting cylinders 11 are electrically connected to the control center 4 and are synchronously controlled by the control center 4. In the initial position, the component carrying platform 6 is located between conveyor belt 1 and conveyor belt 2, and its height is lower than the height of the two conveyor belts, and does not affect the transmission of the photovoltaic component 7 on the conveyor belt. When the photovoltaic component 7 is transmitted to the bottom of the electrostatic collection device 8, the transmission motor 3 stops running, and the lifting cylinder 11 starts running after receiving the control signal. The four telescopic support rods 12 can lift the component carrying platform 6 upward under the drive of the lifting cylinder 11. When the lifting height exceeds the height of the conveyor belt, the photovoltaic component 7 is supported on the upper surface of the component carrying platform 6, and the component carrying platform 6 continues to ascend until it reaches the preset height, providing upward power and static pressure for the contact between the photovoltaic component 7 and the electrostatic collection device 8.

[0036] In a specific embodiment, a pressure sensor 10 is also provided at the connection position between the four telescopic support rods 12 and the component carrying platform 6. The pressure sensor 10 is electrically connected to the control center 4 and is used to obtain the load force between the photovoltaic component 7 and the electrostatic collection device 8 in real time. The load force is used to determine whether the contact degree between the photovoltaic component 7 and the electrostatic collection device 8 has reached a preset standard, and then the operation and stop of the lifting cylinder 11 are controlled to realize automated operation.

[0037] In some optional embodiments, the upper surface of the component carrying platform 6 is paved with a flexible conductive material, the purpose of which is to protect the glass surface of the photovoltaic component 7 and to conduct static electricity from the glass surface. Optionally, the flexible conductive material can be an SBS-based conductive composite material, which is usually made of SBS (styrene-butadiene-styrene block copolymer) as a matrix, and is prepared into fibers by adding conductive fillers and then spinning. For example, the conductive filler can be carbon nanotubes (CNTs), graphene, etc. to enhance its conductivity.

[0038] In a specific embodiment, the surface of the flexible conductive material is provided with anti-slip protrusions so as to better cooperate with the photovoltaic component 7 .

[0039] In a specific embodiment, the electrostatic collection device 8 is a flexible body as a whole, the inner layer of which is a flexible waterproof fabric, and the outer layer is a conductive material. The inner layer forms a closed cavity, and the cavity is filled with a freely flowing fluid. The fluid is preferably a liquid, and further, preferably water. Water can adaptively drive the flexible conductive material to cover the entire surface of the photovoltaic component 7 to achieve full contact.

[0040] In some optional embodiments, the conductor material of the outer layer of the static electricity collection device 8 is a graphene conductive film, which has good flexibility and stable conductivity, can achieve full contact with the photovoltaic module 7 under the action of the internal fluid, and has excellent conductivity, and can quickly conduct static electricity. In addition, the graphene conductive film also has super fatigue resistance, which is very suitable for repeated operations on the production line.

[0041] It should be understood that the shape of the electrostatic collection device 8 is set to be a rectangle like the photovoltaic module 7, and four suspension ropes 9 are fixedly connected to the top surface near the four corners. The other ends of the four suspension ropes 9 are connected to the frame 5 through fixings. When using it for the first time, the suspension ropes 9 are adjusted as needed so that the electrostatic collection device 8 can be at a suitable height position. In later production, it can be adjusted at any time as needed.

[0042] It should be understood that, in practical applications, the lifting cylinder 11 may also be other driving structures or mechanical devices capable of realizing linear motion functions / rotational motion / telescopic motion, for example, a servo motor, a hydraulic cylinder, an electric cylinder, and the like.

[0043] The component transmission line can be a belt transmission mechanism in this embodiment, or other transmission devices that convert rotational motion into linear motion. This embodiment does not limit the specific type of the transmission device. It only needs to be provided with a lifting mechanism in the component transmission line to lift the photovoltaic component 7 away from the transmission line and to a preset height. It should be noted that the component carrying platform 6 on the top of the lifting mechanism needs to have a certain area so as to form effective support and surface contact for the photovoltaic component 7.

[0044] In some embodiments, the position sensor 14 can be an infrared sensor, a photoelectric sensor, etc. The position sensor is electrically connected to the control center 4. The position sensor 14 can monitor the position signal of the photovoltaic component 7. The control center 4 converts the received position signal into a power-off signal of the transmission motor 3 of the conveyor belt. The control center 4 then controls the transmission motor 3 to automatically disconnect the power supply, so that the component transmission line stops running. By setting the above position sensor, the operation of the device of the present invention can be automatically identified and controlled, making the operation efficiency more efficient.

[0045] An embodiment of the present invention further provides a method for eliminating static electricity in a photovoltaic module production line. The method uses the photovoltaic module production line static electricity elimination device in the above embodiment. The method includes the following steps:

[0046] Acquire a position signal of the photovoltaic component 7 reaching the top of the component carrying platform 6 collected by the position sensor 14;

[0047] Controlling the component transmission line to pause according to the position signal; at the same time, controlling the lifting mechanism to move upward according to the position signal;

[0048] Control the lifting mechanism to move upward to a preset height, so that the photovoltaic assembly 7 located above the assembly carrying platform 6 is in contact with the electrostatic collection device 8, and maintain a preset threshold pressure on the photovoltaic assembly 7, so that the surface of the photovoltaic assembly 7 is in full contact with the electrostatic collection device 8;

[0049] The control wire 13 is turned on and kept on for 10 seconds to conduct static electricity;

[0050] The lifting mechanism is controlled to move downward, so that the photovoltaic module 7 falls onto the module transmission line, and the module transmission line is controlled to operate to transport the photovoltaic module 7 to the next position.

[0051] In some embodiments, when the photovoltaic assembly 7 is in contact with the electrostatic collection device 8, a pressure of a preset threshold value of 200 Pa is maintained on the photovoltaic assembly 7 to ensure that the surface of the electrostatic collection device 8 is in full contact with the photovoltaic assembly 7. The pressure value is monitored by a plurality of pressure sensors 10 disposed at the bottom of the assembly carrying platform 6.

[0052] In some embodiments, the height of the lifting mechanism is adaptively adjusted according to the pressure value of the photovoltaic assembly 7. When the pressure sensor 10 detects that the pressure value reaches 200 Pa, the lifting mechanism stops moving upward.
