DETAILED DESCRIPTION

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.

[0030] like Figure 1 As shown:

[0031] A laminating device applied to a fully automatic laminating machine comprises a conveying mechanism 101 for conveying photovoltaic panels and a laminating machine body 102 mounted on a bracket of the conveying mechanism 101.

[0032] In this implementation scheme: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the initial stage after the completion of the current lamination process is the critical period for heat dissipation. Currently, this equipment cannot perform cooling treatment in time, and the cooling time is short. Since the temperature inside the photovoltaic panel is usually at a high level, it is easy to cause immediate damage to the battery cells and packaging materials due to high temperature, and increase the risk of cracks and delamination physical damage." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. The power equipment involved in this product is all powered by an external power supply.

[0033] More specifically:

[0034] like Figure 1-Figure 5 As shown:

[0035] In combination with the above content: a U-shaped frame 104 is provided on one side of the laminating machine body 102, and symmetrically arranged moving plates 105 are provided inside the U-shaped frame 104, and a plurality of equally spaced supporting plates 108 are fixed on the side where two sets of moving plates 105 are close to each other;

[0036] The U-shaped frame 104 is provided with an adjustment mechanism 3 for adjusting the spacing between the support plates 108 on both sides. By adjusting the multiple groups of support plates 108 on both sides, photovoltaic panels of different sizes can be supported.

[0037] The adjustment mechanism 3 includes a connection block 301 welded to the upper surface of the moving plate 105, a threaded barrel 304 disposed between two sets of connection blocks 301, and a threaded rod 303 threadedly connected through threaded holes provided at both ends of the threaded barrel 304;

[0038] A symmetrically arranged fixing plate 302 is fixed on one side of the surface of the U-shaped frame 104 close to the threaded cylinder 304. The threaded cylinder 304 is rotatably connected to the two sets of fixing plates 302 through a bearing. The connecting block 301 is fixedly connected to the threaded rod 303. The threads of the two sets of threaded rods 303 are designed in opposite structures.

[0039] The upper surface of the U-shaped frame 104 is provided with a limiting groove 305 adapted to the connection block 301. The connection block 301 and the U-shaped frame 104 are slidably connected through the limiting groove 305, and the limiting groove 305 is used to limit the movement of the connection block 301;

[0040] A plurality of exhaust cooling fans 106 are fixedly mounted on the surface of one set of movable plates 105 through the first mounting holes, and an intake cooling fan 107 is fixedly mounted on the surface of another set of movable plates 105 through the second mounting holes.

[0041] An intermittent lifting mechanism 2 is installed on the bracket of the conveying mechanism 101, which can lift the U-shaped frame 104;

[0042] The intermittent lifting mechanism 2 includes two groups of L-shaped brackets 201 symmetrically arranged and fixedly mounted on the bracket of the conveying mechanism 101 by bolts, an electric push rod 202 mounted on the surface of the L-shaped bracket 201 by screws, and a mounting seat 203 fixed on the surface of the U-shaped frame 104 near the output end of the electric push rod 202, and the output end of the electric push rod 202 is fixedly connected to the mounting seat 203;

[0043] A blocking and resisting mechanism 4 for blocking the photovoltaic panel is installed on one side of the support plate 108;

[0044] The blocking and resisting mechanism 4 includes a rotating shaft rod 403 fixed to one side of the support plate 108, a shielding plate 401 rotatably connected to one end of the rotating shaft rod 403 through a bearing, and a return torsion spring 402 wound around the surface of the rotating shaft rod 403;

[0045] The two ends of the return torsion spring 402 are fixedly connected to the support plate 108 and the shielding plate 401 respectively;

[0046] A laser sensor 103 is fixedly mounted on the bracket of the conveying mechanism 101;

[0047] Rectangular holes are provided on both sides of the U-shaped frame 104 , and the two groups of rectangular holes correspond to the exhaust cooling fan 106 and the intake cooling fan 107 respectively, and a heat dissipation channel can be formed through the rectangular holes.

[0048] In this embodiment: the laminating device applied to the fully automatic laminating machine, when in use, firstly places the photovoltaic panel to be hot pressed on the conveying mechanism 101 for conveying, and as the conveying mechanism 101 continuously conveys, the photovoltaic panel is conveyed to the position of the laminating machine body 102 for hot pressing and laminating treatment;

[0049] After the hot pressing is completed, the conveying mechanism 101 continues to convey the photovoltaic panel. During this process, when the laser sensor 103 detects that the photovoltaic panel has passed, it controls the electric push rod 202 to extend, and drives the U-shaped frame 104 to move down synchronously through the mounting seat 203, until the U-shaped frame 104 drives the moving plate 105 and the support plate 108 to move down synchronously, until the bottom support plate 108 and the shaft cylinder of the conveying mechanism 101 are at the same horizontal plane, and the operation of the electric push rod 202 is stopped. During this process, driven by the conveying mechanism 101, the photovoltaic panel moves to the top of the two groups of support plates 108;

[0050] When the photovoltaic panel moves onto the support plate 108, the shielding plate 401 at one end of the support plate 108 can block the photovoltaic panel to prevent the photovoltaic panel from being separated from the support plate 108 due to inertia, and falling and being damaged;

[0051] When the laser sensor 103 detects the photovoltaic panel sliding on the conveying mechanism 101, the electric push rod 202 is started to drive the moving plate 105 and the supporting plate 108 to move down to a certain distance synchronously, so that the supporting plate 108 placed above the photovoltaic panel corresponds to the shaft cylinder (not shown in the figure) of the conveying mechanism 101. At this time, the photovoltaic panel is transported to the supporting plate 108 again. Through this operation, the photovoltaic panels after heat pressing are continuously stored;

[0052] In this process, the exhaust cooling fan 106 and the intake cooling fan 107 are started, and the wind force generated by the intake cooling fan 107 is used to dissipate heat, while the exhaust cooling fan 106 quickly discharges heat to achieve heat dissipation of the photovoltaic panel;

[0053] Through this operation, after the photovoltaic panels are heated by pressure, they are directly transported to the support plate 108 for stacking, and the heat dissipation operation can be realized. Timely heat dissipation and long heat dissipation time can reduce the accumulation of thermal stress and reduce the risk of physical damage such as cracks and delamination of the photovoltaic panels. Long-term high temperature will accelerate the aging and performance degradation of various materials in the photovoltaic panels. In addition, multiple groups of photovoltaic panels are stacked in order on the support plate 108. Long-term and efficient heat dissipation can keep the photovoltaic panels within a suitable operating temperature range. When the temperature drops, the resistance of the semiconductor material inside the photovoltaic panel decreases, and the mobility of electrons and holes increases, thereby improving the photoelectric conversion efficiency. This means that under the same lighting conditions, more electricity can be generated, bringing more benefits to users. Rapid changes in temperature can cause thermal stress inside the photovoltaic panel;

[0054] When the photovoltaic panels are stacked on multiple groups of support plates 108, after one group of photovoltaic panels is left idle on the support plates 108 for a certain period of time to dissipate heat, the staff rotates the shielding plate 401, so that the shielding plate 401 rotates on the rotating shaft rod 403, and drives the reset torsion spring 402 to produce a certain elastic deformation, so that the shielding plate 401 rotates to 90°, and the shielding plate 401 is flush with the support plate 108, and the resistance to the photovoltaic panels is released, and then the photovoltaic panels are removed. In this process, the photovoltaic panels placed first are effectively removed, so that the heat dissipation time can be the same and the heat dissipation is consistent;

[0055] Before the photovoltaic panel is placed on the support plate 108, the threaded cylinder 304 can be rotated. Since the threaded rod 303 and the threaded cylinder 304 are threadedly connected, and the threads of the two groups of threaded rods 303 are designed in opposite structures, the threaded rods 303 are driven to move away from or closer to each other, and then the connecting block 301 is driven to move in the limiting groove 305 opened on the U-shaped frame 104. Through the setting of the limiting groove 305, the connecting block 301 can be limited, so that the connecting block 301 is more stable during the movement. Through the movement of the connecting block 301, the movable plate 105 and the support plate 108 are driven to move synchronously, so as to adjust the distance between the support plates 108, so as to better adapt to photovoltaic panels of different sizes for support operations.

[0056] It should be noted that the laser sensor 103 works by emitting a laser beam and receiving the reflected laser. When there is no object within its detection range, the laser beam propagates along a predetermined path, and the reflected signal is in a stable state. When an object moves into the detection area of ​​the laser sensor 103, the laser beam will be reflected by the object, causing the reflected signal to change. This change will be captured and processed by the sensor's detection circuit. In order to control the electric push rod 202 to extend a certain distance, the laser sensor 103 converts the detected object movement signal into an electrical signal and transmits it to the controller. After receiving this signal, the controller will process it according to the preset program and algorithm. During the processing, the controller will calculate the relevant parameters of the object's movement, such as the speed, direction, and distance of the movement. Then, based on these parameters and the preset control strategy, the distance that the electric push rod 202 needs to extend is determined.

[0057] Going further;

[0058] In an optional embodiment, a plurality of groups of equally spaced strip holes are provided on the surface of the support plate 108, and a roller 109 is disposed in the strip holes. The roller 109 is rotatably connected to the support plate 108 via a bearing, and the top of the roller 109 is higher than the upper surface of the support plate 108. The roller 109 is used to reduce the friction between the photovoltaic panel and the support plate 108.

[0059] In this embodiment: since multiple groups of rollers 109 are provided on the support plate 108, when the photovoltaic panel rolls on the support plate 108, the friction between the support plate 108 and the photovoltaic panel can be reduced, thereby avoiding damage to the photovoltaic panel and improving the use effect of the device.

[0060] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
