Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module production technology, specifically a lamination device for photovoltaic panel production and processing. Background Technology

[0002] As the core component of a solar power generation system, photovoltaic (PV) panels primarily convert solar energy into electrical energy. A typical PV module structure includes a backsheet, a lower EVA film, solar cells, an upper EVA film, and a tempered glass layer, all laminated together to form an integrated finished product. The quality of PV modules directly affects the performance and stability of the solar power generation system; therefore, ensuring excellent quality and consistency in the production process is crucial for the stable operation of the PV power generation system.

[0003] In the production of photovoltaic modules, lamination is a crucial step. Current lamination equipment primarily uses technologies such as heating, vacuuming, and extrusion to laminate photovoltaic modules. The heating mechanism heats the photovoltaic module, softening the EVA film and promoting bonding between the layers. The vacuum mechanism evacuates the lamination chamber to remove air bubbles from the photovoltaic module. The lamination mechanism then uniformly extrudes the module, ensuring effective bonding of each layer to improve the photoelectric conversion efficiency and reliability of the photovoltaic panel.

[0004] Patent application CN118919591B discloses a lamination device for photovoltaic module production. The key technical points of the device are: it includes a housing with inlets and outlets and a top plate mounted on the housing; the housing contains a heating mechanism, a vacuum mechanism, and a lamination mechanism; the heating mechanism heats the photovoltaic module; the vacuum mechanism evacuates the housing; and the lamination mechanism presses the photovoltaic module from the center outwards to expel air bubbles. This invention, through the lamination mechanism and the expansion of an elastic airbag driven by a first driving mechanism, achieves flexible compression of the photovoltaic module. When a large number of air bubbles make the photovoltaic panel uneven, the flexible compression of the elastic airbag, achieved by filling the airbag with a uniform medium, ensures uniform force on the photovoltaic module, preventing damage due to uneven force.

[0005] However, the aforementioned technologies often have the following drawbacks: Existing technologies use clamping mechanisms to automatically position and clamp photovoltaic modules, but the photovoltaic panels automatically descend into the mounting frame under gravity, making it difficult to remove them after lamination, thus affecting production efficiency, increasing the labor intensity of operators, and reducing the overall efficiency of the production line. Therefore, this invention provides a lamination device for photovoltaic panel production and processing. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is: a lamination device for photovoltaic panel production and processing, comprising:

[0011] A connecting pipe is fixed to the top of the sealing cover and is connected to an external vacuum pump.

[0012] Preferably, the clamping member includes a base plate, a top plate is provided above the base plate, a spring is installed between the base plate and the top plate, slide rails are symmetrically installed on the opposite side walls of the base plate and the top plate, and scissor frames are movably installed on the slide rails on both sides, and the scissor frames on both sides are connected by a connecting rod.

[0013] Preferably, guide rods are symmetrically fixed around the top of the pressure plate, and the guide rods slide through to the outer side of the top of the sealing cover. A second spring is sleeved on the inner side of the guide rod and a first spring is sleeved on the outer side of the guide rod.

[0014] Preferably, a frame is fixed above the workbench, the frame is composed of two L-shaped plates arranged opposite each other, the mounting plate is movably installed in the middle of the frame, linear modules are symmetrically fixed on both sides of the frame, and connecting frames are movably connected to the linear modules on both sides. The connecting frames on both sides are fixed to the top of the mounting plate on both sides. A conveyor belt is provided on the side of the workbench, and a negative pressure component is provided inside the pressure plate. The negative pressure component adsorbs the photovoltaic panel so that the photovoltaic panel can be transferred to the conveyor belt by the linear module.

[0015] Preferably, the negative pressure assembly includes an inner cavity in the middle of a pressure plate, through holes symmetrically opened on the lower end face of the pressure plate, a plug block slidably installed in the through holes, a spring three fixed in the inner cavity of the pressure plate, the spring three supporting the plug block so that the lower end face of the plug block is flush with the lower end face of the pressure plate, a spring tube fixed on the top of the pressure plate, and the end of the spring tube away from the pressure plate connected to an external vacuum pump.

[0016] Preferably, a solenoid valve is fixed on the top of the frame. The solenoid valve is connected to the air inlet of the vacuum pump. The solenoid valve is provided with a connector one and a connector two. The connector one is connected to a connecting pipe, and the connector two is connected to a spring tube.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The lamination device for photovoltaic panel production and processing described in this invention clamps and limits the photovoltaic panel by setting a limiting component, and can automatically move the photovoltaic panel directly below the center of the pressure plate, thereby making the photovoltaic panel more uniformly stressed and the lamination effect better; in addition, when the spring is in a relaxed state, the height of the top plate is greater than the thickness of the photovoltaic panel. At this time, the scissor frame can simultaneously limit the photovoltaic panel and the layers of structure pressed above it, preventing the structure of the photovoltaic panel surface from shifting during the lamination process, thereby reducing the defect rate.

[0022] 2. The laminating device for photovoltaic panel production and processing described in this invention uses a vacuum pump to evacuate the inner cavity through a spring tube, creating a negative pressure that attracts a blockage block into the cavity. The blockage block disengages from the through-hole, which is then open, allowing suction to be applied to the photovoltaic panel. This suction then transfers the processed photovoltaic panel onto a conveyor belt, enabling automatic unloading and improving work efficiency. Furthermore, since the photovoltaic panel is hot after processing, the above method avoids direct contact between the processed panel and the operator, thus preventing burns.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1: As Figures 1 to 6 As shown in the embodiment of the present invention, a lamination apparatus for photovoltaic panel production and processing includes:

[0033] Workbench 1, with a heating plate 3 fixed in the middle for heating the photovoltaic panel;

[0034] A laminating assembly includes a mounting plate 10, a hydraulic cylinder 11 fixed in the middle of the mounting plate 10, a pressure plate 14 fixed at the bottom end of the telescopic rod of the hydraulic cylinder 11, a sealing cover 4 covering the outer side of the pressure plate 14, the sealing cover 4 being slidably fitted on the telescopic rod, and a spring 19 fixed between the pressure plate 14 and the sealing cover 4.

[0035] A limiting component is symmetrically arranged around the heating plate 3. The limiting component includes a stop block 23 fixed to the side of the heating plate 3. An electromagnetic block 25 is fixed on the side wall of the stop block 23. A sleeve 24 is fixed on the outside of the electromagnetic block 25. A movable rod 27 is slidably connected to the side of the sleeve 24 away from the stop block 23. A spring 26 is fixed between the electromagnetic block 25 and the movable rod 27. A clamping member is fixed to the end of the movable rod 27.

[0036] Connecting pipe 5, which is fixed to the top of sealing cover 4, and is connected to an external vacuum pump;

[0037] During operation, the controller powers the electromagnetic block 25, which generates a magnetic force. The movable rod 27 is attracted by the magnetic force and moves towards the inside of the sleeve 24, thereby driving the clamping parts to move. At this time, the spring 4 26 is compressed. Then, the photovoltaic panel that needs to be laminated is placed on top of the heating plate 3. The controller then de-energizes the electromagnetic block 25, and the magnetic force disappears. Under the rebound action of the spring 4 26, the clamping parts are clamped around the photovoltaic panel. This can limit the position of the photovoltaic panel, and the heating plate 3 is activated to heat the photovoltaic panel to a suitable temperature.

[0038] Then, the hydraulic cylinder 11 is controlled to move, and the telescopic rod of the hydraulic cylinder 11 extends downward, thereby pushing the pressure plate 14 to move downward. At the same time, the sealing cover 4 is driven to move downward through the spring 19. The size of the sealing cover 4 is larger than that of the pressure plate 14, and the sealing cover 4 can cover the heating plate 3 and the limiting component together. The sealing cover 4 first contacts the upper surface of the workbench 1, and the vacuum pump is started. The vacuum pump performs vacuum treatment on the inside of the sealing cover 4 through the connecting pipe 5. Then, the pressure plate 14 contacts the top of the photovoltaic panel so that the various layers of the photovoltaic panel can be stably pressed together. After the processing is completed, the hydraulic cylinder 11 is used to lift the sealing cover 4, and then the electromagnetic block 25 is energized again so as to quickly remove the restriction on the photovoltaic panel and facilitate the quick removal of the processed photovoltaic panel.

[0039] In addition, the limiting components set symmetrically around the perimeter can automatically move the photovoltaic panel to the center of the pressure plate 14, thereby making the photovoltaic panel more uniformly stressed and the lamination effect better.

[0040] The clamping component includes a base plate 28, a top plate 29 is provided above the base plate 28, a spring 30 is installed between the base plate 28 and the top plate 29, slide rails 33 are symmetrically installed on the opposite side walls of the base plate 28 and the top plate 29, and scissor frames 31 are movably installed on the slide rails 33 on both sides, and the scissor frames 31 on both sides are connected by a connecting rod 32.

[0041] During operation, the scissor bracket 31 in the clamping component clamps the side of the photovoltaic panel, limiting its position. Furthermore, when the spring 5 30 is relaxed, the height of the top plate 29 is greater than the thickness of the photovoltaic panel. At this time, the scissor bracket 31 can simultaneously limit the position of the photovoltaic panel and the layers laminated above it. When the pressure plate 14 presses down, it first contacts the top plate 29, pushing the top plate 29 downwards, thereby compressing the scissor bracket 31. This causes the connecting rods 32 on both sides of the scissor bracket 31 to slide along the slide rail 33, allowing the scissor bracket 31 to continuously retract. Simultaneously, the spring 5 30 is compressed, reducing the overall height of the clamping component. However, it remains confined to the side of the photovoltaic panel and the layers laminated above it. This prevents the surface structure of the photovoltaic panel from shifting during lamination, thus reducing the defect rate.

[0042] The top of the pressure plate 14 is symmetrically fixed with guide rods 17. The guide rods 17 slide through to the outside of the top of the sealing cover 4. A second spring 19 is sleeved on the inner side of the guide rod 17 and a first spring 18 is sleeved on the outer side of the guide rod 17.

[0043] During operation, the guide rod 17 supports spring 18 and spring 19, making their movement more stable. By setting spring 19, the sealing cover 4 can move together with the pressure plate 14. During the downward pressing of the pressure plate 14, spring 19 is stretched downward and spring 18 is compressed. Through the cooperation of the two, the sealing cover 4 can fit tightly against the upper surface of the worktable 1 to improve airtightness. In addition, the guide rod 17 can also limit the sealing cover 4, making the sealing cover 4 more stable during its up and down movement.

[0044] A frame 2 is fixed above the workbench 1. The frame 2 is composed of two L-shaped plates arranged opposite each other. The mounting plate 10 is movably installed in the middle of the frame 2. Linear modules 9 are symmetrically fixed on both sides of the frame 2. Connecting frames 12 are movably connected to the linear modules 9 on both sides. The connecting frames 12 on both sides are fixed to the top sides of the mounting plate 10. A conveyor belt 13 is provided on the side of the workbench 1. A negative pressure component is provided inside the pressure plate 14. The negative pressure component adsorbs the photovoltaic panel so that the photovoltaic panel can be transferred to the conveyor belt 13 by the linear module 9.

[0045] During operation, after the lamination step is completed, the vacuum pump is paused, and the pressure relief valve on the sealing cover 4 is opened. The pressure relief valve is not shown in the figure. The pressure relief valve can be an electronic pressure relief valve, which can be controlled to close during vacuuming and open during pressure relief. The pressure relief valve releases the internal pressure of the sealing cover 4, preventing the sealing cover 4 from adhering to the workbench 1. Then, the photovoltaic panel is adsorbed by the negative pressure component. Then, the linear module 9 is started. The linear module 9 drives the mounting plate 10, hydraulic cylinder 11, and pressure plate 14 to transfer the photovoltaic panel to the conveyor belt 13 (the installation method, driving method, and control method of the conveyor belt 13 are all existing public technologies and will not be described in detail here). This enables automatic unloading of the processed photovoltaic panel and improves work efficiency. In addition, the photovoltaic panel is hot after processing. The above method can avoid direct contact between the processed photovoltaic panel and the operator, thus avoiding burns.

[0046] The negative pressure assembly includes an inner cavity in the middle of a pressure plate 14. Symmetrical through holes are provided on the lower end face of the pressure plate 14. A block 21 is slidably installed in the through holes. A spring 22 is fixed in the inner cavity of the pressure plate 14. The block 21 is supported by the spring 22 so that the lower end face of the block 21 is flush with the lower end face of the pressure plate 14. A spring tube 20 is fixed on the top of the pressure plate 14. The spring tube 20 can be stretched or shortened as the pressure plate 14 moves. The end of the spring tube 20 away from the pressure plate 14 is connected to an external vacuum pump.

[0047] During operation, the vacuum pump evacuates the inner cavity through the spring tube 20, creating a negative pressure in the inner cavity. This attracts the block 21 to move into the inner cavity, causing the block 21 to disengage from the through hole. The through hole is then open, allowing suction to be applied to the photovoltaic panel through the through hole. This suction can then be used to transfer the processed photovoltaic panel onto the conveyor belt 13.

[0048] The top of the frame 2 is fixed with a solenoid valve 6, which is connected to the air inlet of the vacuum pump. The solenoid valve 6 is provided with a connector 7 and a connector 8. The connector 7 is connected to the connecting pipe 5, and the connector 8 is connected to the spring tube 20.

[0049] During operation, in the lamination process, the solenoid valve 6 controls the connecting pipe 5 to be connected to the vacuum pump through the connector 7. At this time, the vacuum pump can be used to evacuate the inside of the sealing cover 4. When it is necessary to transfer the processed photovoltaic panel, the solenoid valve 6 controls the spring tube 20 to be connected to the vacuum pump through the connector 8. At this time, the vacuum pump can be used to create a negative pressure environment in the inner cavity of the pressure plate 14 so that the photovoltaic panel can be transferred by suction.

[0050] A sealing gasket 34 is fixed to the lower end face of the sealing cover 4, and the sealing gasket 34 is hollow in the middle. During operation, the sealing gasket 34 makes the contact between the sealing cover 4 and the worktable 1 tighter, further improving the airtightness.

[0051] The sidewalls of the base plate 28, top plate 29, and scissor bracket 31 are kept flush in the vertical direction; during operation, the clamping component can fit against the side of the photovoltaic panel and will not damage the photovoltaic panel during up and down movement.

[0052] Example 2: Figure 3 As shown in the first embodiment, another embodiment of the present invention is as follows: a sliding groove 15 is provided on the opposite side wall of the frame 2 on both sides, and a slider 16 is fixed on both sides of the mounting plate 10. The slider 16 is slidably disposed in the sliding groove 15. During operation, by setting the sliding groove 15 and the slider 16, the mounting plate 10 can be stably installed on the frame 2.

[0053] Working principle: When the electromagnetic block 25 is energized, it generates a magnetic force. The movable rod 27 is attracted by the magnetic force and moves towards the inside of the sleeve 24, thereby driving the clamping parts to move. At this time, the spring 4 26 is compressed. Then, the photovoltaic panel that needs to be laminated is placed on the top of the heating plate 3. Then, the controller is used to de-energize the electromagnetic block 25, the magnetic force disappears, and the clamping parts are clamped around the photovoltaic panel under the rebound action of the spring 4 26. This can limit the position of the photovoltaic panel, and the heating plate 3 is started to heat the photovoltaic panel to a suitable temperature.

[0054] Then, the hydraulic cylinder 11 is controlled to move. The telescopic rod of the hydraulic cylinder 11 extends downward, thereby pushing the pressure plate 14 to move downward. At the same time, the sealing cover 4 is driven to move downward through the spring 19. The size of the sealing cover 4 is larger than that of the pressure plate 14, and the sealing cover 4 can cover the heating plate 3 and the limiting component together. The sealing cover 4 first contacts the upper surface of the worktable 1. The vacuum pump is started. The vacuum pump performs vacuum treatment on the inside of the sealing cover 4 through the connecting pipe 5. Then, the pressure plate 14 contacts the top of the photovoltaic panel so that the various layers of the photovoltaic panel can be stably pressed together.

[0055] The scissor frame 31 in the clamping component clamps the side of the photovoltaic panel to clamp and limit the photovoltaic panel. In addition, when the spring 5 30 is in a relaxed state, the height of the top plate 29 is greater than the thickness of the photovoltaic panel. At this time, the scissor frame 31 can simultaneously limit the photovoltaic panel and the various layers of the structure pressed above it. When the pressure plate 14 presses down, it first contacts the top plate 29 and pushes the top plate 29 downward, thereby compressing the scissor frame 31 so that the connecting rods 32 on both sides of the scissor frame 31 slide along the slide rail 33, so that the scissor frame 31 continues to close. At the same time, the spring 5 30 is compressed, and the overall height of the clamping component is reduced, but it is always limited to the side of the photovoltaic panel and the various layers of the structure pressed above it. This can prevent the structure of the surface layer of the photovoltaic panel from shifting during the lamination process, thereby reducing the defect rate.

[0056] After the lamination step is completed, the vacuum pump is paused, and the pressure relief valve on the sealing cover 4 is opened. The pressure relief valve is not shown in the figure. The pressure relief valve can be an electronic pressure relief valve, which can be controlled to close during vacuuming and open during pressure relief. The pressure relief valve releases the internal pressure of the sealing cover 4, preventing the sealing cover 4 from adhering to the workbench 1. Then, the photovoltaic panel is adsorbed by the negative pressure component. The linear module 9 is then started. The linear module 9 drives the mounting plate 10, hydraulic cylinder 11, and pressure plate 14 to transfer the photovoltaic panel to the conveyor belt 13, so as to realize the automatic unloading of the processed photovoltaic panel and improve work efficiency. In addition, the photovoltaic panel is hot after processing. The above method can avoid direct contact between the processed photovoltaic panel and the operator, thus avoiding burns.
