Abstract
Description

Therefore, when laminating different types of photovoltaic modules, it is necessary to adjust the feed of the hydraulic cylinder. Generally, when the distance between the pressure plate and the top of the photovoltaic module is relatively close, it starts to run slowly to avoid over-compression. However, when the height of the photovoltaic module changes, it is necessary to change the feed of the hydraulic cylinder to avoid damage caused by long lamination time or excessive feed speed.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-3 In this embodiment of the present invention, a laminating device for producing PVT photovoltaic thermal modules includes a conveying device 1. A connecting box 2 is fixedly installed on the top of the two end plates of the conveying device 1. A channel for the stacked photovoltaic panels to enter is provided between the two side plates of the connecting box 2 and the top of the conveyor belt of the conveying device 1. A closing mechanism is slidably installed on both sides of the top plate of the connecting box 2. A pressure plate assembly is installed inside the connecting box 2. An adjustment mechanism is fixedly installed at the top center of the pressure plate assembly, extending through the connecting box 2 and the closing assembly. The top of the adjustment mechanism is connected to the piston rod of a hydraulic cylinder. A support plate 11 for supporting the conveyor belt of the conveying device 1 is fixedly installed between the two end plates of the conveying device 1. Multiple reinforcing ribs 12 are fixedly installed between the two end plates of the conveying device 1 at the bottom of the support plate 11. An exhaust pipe 10 is fixedly installed at one end of the connecting box 2. The exhaust pipe 10 is connected to the inner cavity of the connecting box 2. The sliding column 16 is integrally formed on the outer wall above the connecting box 2 with a lifting plate 15 that pushes the synchronous plate 4 to reset upward. A fixing plate 6 is fixedly installed on the top of the sliding column 16. Two symmetrically arranged brackets 7 are fixedly installed on the top of the fixing plate 6. A spring 9 abuts between the bottom end of the fixing plate 6 and the top end of the synchronous plate 4. The spring 9 is sleeved on the outer periphery of the sliding column 16. There is a space between the two brackets 7. The top of the brackets 7 is connected to the piston rod of the hydraulic cylinder through a flange.
[0020] In this embodiment: First, the stacked photovoltaic modules (from top to bottom: glass, EPE, solar cells, EVA, insulating board, EVA, full-channel substrate, EVA, thermal insulation backsheet) are placed on top of the conveying device 1. The conveying device 1 carries the photovoltaic modules into the inner cavity of the connecting box 2. Then, the conveying device 1 is closed. At this time, the hydraulic cylinder is activated, which pushes the bracket 7 downward. The bracket 7 pushes the sliding column 16 downward through the fixing plate 6. At this time, the sealing mechanism moves downward under gravity until the bottom end of the sealing mechanism contacts and squeezes the top of the conveyor belt of the conveying device 1, completing the channel sealing. After the channel is sealed, the negative pressure pump is started. The negative pressure pump extracts the gas in the connecting box 2 through the pipe and exhaust pipe 10 to form a negative pressure. At this time, the gas between the various parts of the stacked photovoltaic module is effectively released, and the electric heater inside the connecting box 2 is turned on. The electric heater converts electrical energy into heat energy and radiates it onto EPE and EVA, causing them to melt and form an adhesive force. Then, the hydraulic cylinder that continues to move downward continues to push the sliding column 16 downward until the pressure plate assembly applies the rated pressure to the stacked photovoltaic module. Under the downward pressure, the various parts of the photovoltaic module are bonded together by adhesive force.
[0021] When laminating different types of photovoltaic panels, their stacking height will vary depending on the model. In this case, by rotating the adjustment mechanism, the initial height of the pressing mechanism can be changed to accommodate photovoltaic modules of different thicknesses, without the need to adjust the travel distance of the hydraulic cylinder.
[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The sealing mechanism includes sealing plates 3 that are slidably installed on both sides of the top plate of the connecting box 2. The top of the two sealing plates 3 is fixedly connected to a synchronous plate 4. A sealing element is installed at the bottom of the sealing plate 3. A square groove is opened inside the connecting box 2 for the sealing plate 3 to slide downward. A sealing element is installed on the inner wall of the square groove that contacts the sealing plate 3.
[0023] In this embodiment: During the downward movement of the hydraulic cylinder, the lifting plate 15 moves downward synchronously with the sliding column 16. At this time, the synchronizing plate 4 and the two sealing plates 3 move downward synchronously under gravity until the bottom end of the sealing plate 3 contacts the conveyor belt. At this time, the hydraulic cylinder, which continues to move downward, squeezes the spring 9. The reaction force generated by the compressed spring 9 acts on the top of the synchronizing plate 4 and then acts on the sealing plate 3 through the synchronizing plate 4, thus completing the sealing.
[0024] Please refer to this carefully. Figure 3The adjustment mechanism includes an adjustment screw 8 rotatably mounted on the top of the pressure plate assembly. The adjustment screw 8 extends upward and passes through the top of the synchronization plate 4. A sliding column 16 is threadedly connected to the outer wall of the adjustment screw 8. The sliding column 16 is slidably connected to the connecting box 2. The bottom end of the sliding column 16 passes through the inner cavity of the connecting box 2.
[0025] In this embodiment: when adjusting the height of the pressure plate assembly, the wrench enters between the two brackets 7 and engages with the hexagonal block at the top of the adjusting screw 8. At this time, the adjusting screw 8 can be rotated by turning the wrench. The adjusting screw 8 will rotate upward or downward when rotating, thereby driving the pressure plate assembly to adjust its height to accommodate photovoltaic modules of different heights, without the need to adjust the feed distance of the hydraulic cylinder.
[0026] Please refer to this carefully. Figure 3 The pressure plate assembly includes an upper pressure plate 13 rotatably mounted on the bottom end of the adjusting screw 8, a lower pressure plate 14 mounted on the bottom end of the upper pressure plate 13, and an upwardly protruding guide rod 5 integrally formed at the four corners of the top of the upper pressure plate 13. The guide rod 5 extends through to the top of the synchronous plate 4, and the guide rod 5 is slidably connected to the synchronous plate 4 and the connecting box 2. A sealing ring is installed at the sliding connection position between the connecting box 2 and the guide rod 5. Pressure sensors are installed at the four corners of the mating surfaces of the upper pressure plate 13 and the lower pressure plate 14. The four pressure sensors are connected through a Wheatstone bridge circuit.
[0027] In this embodiment: as the hydraulic cylinder continues to move downward, the sliding column 16 pushes the upper pressure plate 13 and the lower pressure plate 14 downward through the adjustment mechanism until the bottom end of the lower pressure plate 14 contacts and squeezes the top of the photovoltaic module. The reaction force generated by the squeezing acts on the pressure sensor through the lower pressure plate 14. When the rated pressure is reached, the pressure signal is converted into an electrical signal and sent to the controller. The controller can then control the hydraulic cylinder to stop running, avoiding damage to the photovoltaic module caused by excessive compression.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
