[0035] Embodiment one: as Figures 1-6The technical scheme is shown, the roller type laminator, in order to solve the problem of large energy consumption of vacuumizing, discloses the following: the base 1 and the lower silica gel roller 2 installed in the center of the base 1, and the outer side of the base 1 is fixedly installed with the fixed frame 3, and the upper end of the fixed frame 3 is provided with the hydraulic rod 4, and the output end of the hydraulic rod 4 is provided with the adjusting plate 5, the lower end of the adjusting plate 5 is provided with the movable frame 6, and the inside of the movable frame 6 is provided with the upper silica gel roller 7, and the surface of the base 1 is provided with the photovoltaic module 8; the inside of the left side of the base 1 is installed with the preheating plate 14, the front end of the base 1 is installed with the first on-off button 15, and the first on-off button 15 is connected with the preheating plate 14, and the right side of the base 1 is installed with the auxiliary heating and pressing mechanism, the auxiliary heating and pressing mechanism is provided with the processing bin 17, and the rear end of the processing bin 17 is fixedly installed on the outer side of the fixed frame 3, and the inside of the processing bin 17 is installed with the second on-off button 21, and the inside of the right side of the base 1 is provided with the heating plate 16, and the heating plate 16 and the second on-off button 21 are connected through the connecting wire 22, the inside of the processing bin 17 is provided with the pressing plate 18, and the rear end of the pressing plate 18 is fixedly installed with the contact block 19, and the rear end of the contact block 19 passes through the fixed frame 3, and the pressing plate 18 and the processing bin 17 are provided with the reset spring 20, the pressing plate 18 corresponds to the second on-off button 21, the right side of the base 1 is fixedly installed with the driving motor 9, and the output end of the driving motor 9 is fixedly installed with the reciprocating screw rod 10, and the both ends of the reciprocating screw rod 10 are rotatably installed at the rear end of the base 1, and the surface of the reciprocating screw rod 10 is screwedly installed with the moving dial plate 11, the front end of the moving dial plate 11 is installed with the limiting rod 12, and the both ends of the limiting rod 12 are fixedly installed at the front end of the base 1, and the right end of the moving dial plate 11 is fixedly installed with the anti-deviation frame 13, and the anti-deviation frame 13 is located on the outer side of the photovoltaic module 8, and the moving dial plate 11 corresponds to the contact block 19.

[0036] In use, the photovoltaic module 8 is placed on the upper part of the base 1. By pressing the first start / stop button 15, the preheating plate 14 can be activated. The preheating plate 14 can preheat the placed photovoltaic module 8 in advance. After preheating, the glass inside the photovoltaic module 8 and the EVA or PVB adhesive in the cells melt. At this time, the drive motor 9 is activated, which drives the reciprocating threaded rod 10 to rotate. When the reciprocating threaded rod 10 rotates, it drives the moving dial plate 11 with the surface thread connection. Under the limit of the limit rod 12, the moving dial plate 11 can move left and right with the rotation of the reciprocating threaded rod 10. When the moving dial plate 11 moves and adjusts, it can push the photovoltaic module 8 under the setting of the anti-deviation frame 13. When the photovoltaic module 8 moves between the lower silicone roller 2 and the upper silicone roller 7, the hydraulic rod 4 is activated. When the hydraulic rod 4 is activated, it can push the adjusting plate 5. The adjusting plate 5 drives the lower movable frame 6 to move. The silicone roller 7 presses down on the bottom of the frame 6 to press down on the photovoltaic module 8. As the photovoltaic module 8 continues to be pushed, stable lamination is achieved, and the air in the photovoltaic module 8 is forced out. After pre-pressing, the photovoltaic module 8 is sent to the surface of the heating plate 16. At this time, as the moving dial 11 is pushed to the right, the moving dial 11 correspondingly moves the contact block 19. When the contact block 19 is squeezed, it pushes the pressing plate 18 outward. The pressing plate 18 compresses the reset spring 20 inside the processing chamber 17 and presses the second on / off button 21. Under the action of the connecting wire 22, the second on / off button 21 starts the heating plate 16, so that the adhesive can be fully melted and the photovoltaic module 8 can be cured, thus completing the module manufacturing process. Conversely, under the reset and tossing action of the moving dial 11, the heating plate 16 can be automatically turned off, achieving the effect of convenient use. There is no need to be in a vacuum environment for lamination, which can save resources.

[0037] Example 2: Figures 1-8 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of easy damage to solar modules during lamination: a rotating plate 26 is provided at the lower end of the adjusting plate 5, and an adjusting block 25 is provided at the lower end of the rotating plate 26. An auxiliary lamination protection mechanism is provided on the outer side of the adjusting block 25. The auxiliary lamination protection mechanism is provided with a guide rod 24, and the middle end of the guide rod 24 is installed through the interior of the adjusting block 25. Vertical plates 23 are fixedly installed at both ends of the guide rod 24. The lower end of the vertical plate 23 is fixedly installed on the upper surface of the movable frame 6. The upper and lower ends of the rotating plate 26 are rotatably connected to the adjusting plate 5 and the adjusting block 25 through a rotating shaft. A damper 28 is installed through the interior of the adjusting plate 5, and the lower end of the damper 28 is installed on the surface of the movable frame 6. A buffer spring 27 is provided on the inner side of the adjusting block 25, and the inner side of the buffer spring 27 is installed on the outer side of the vertical plate 23.

[0038] During lamination, the hydraulic rod 4 is activated to push the adjusting plate 5. The adjusting plate 5, pushed by the hydraulic rod 4, presses down the rotating plate 26. When the rotating plate 26 is pressed down, it pushes the adjusting block 25. When the adjusting block 25 is pushed, it can slide along the guide rod 24 on the inner side of the upright plate 23. The adjusting block 25, through the elasticity of the buffer spring 27 and the setting of the damper 28, can buffer and protect the downward force, so that the hard contact force of the upper silicone roller 7 pressing down on the photovoltaic module 8 becomes soft, which can further protect the photovoltaic module 8, ensure the quality of the photovoltaic module 8 during lamination, and avoid damage to the photovoltaic module 8.

[0039] Example 3: Figures 1-10 The technical solution shown, based on Embodiment 2, discloses the following to address the issue of easy damage to the edges of solar modules: A vertical rod 31 is provided at the outer end of the movable frame 6, and an outer protective mechanism is installed at the bottom of the vertical rod 31. The outer protective mechanism is equipped with a traction rope 29, and the inner end of the traction rope 29 is fixedly installed on the outer side of the adjusting block 25. A guide wheel is provided at the middle end of the traction rope 29, and the lower end of the traction rope 29 is fixedly installed on the surface of the lifting plate 30. The upper end of the lifting plate 30 is fixedly installed at the lower end of the vertical rod 31, and the upper end of the vertical rod 31 passes through the movable frame 6. An adjusting pull plate 32 is fixedly installed at the lower end of the lifting plate 30, and the middle end of the adjusting pull plate 32 is sleeved on the front and rear ends of the upper silicone roller 7. The lower end of the adjusting pull plate 32 corresponds to the outer side of the upper silicone roller 7.

[0040] When the upper silicone roller 7 presses down on the photovoltaic module 8, as the hydraulic rod 4 continues to press down, the adjusting plate 5 further presses down on the rotating plate 26. The rotating plate 26 pushes the adjusting block 25 to move inward. As the adjusting block 25 moves, it pulls the traction rope 29. The traction rope 29 pulls the lifting plate 30 under the downward movement of the guide wheel. The lifting plate 30 can be height adjusted under the limit of the vertical rod 31. At the same time, when the lifting plate 30 rises, it can pull the adjusting pull plate 32, so that the adjusting pull plate 32 pulls the edge position of the upper silicone roller 7. This avoids the pressure difference between the center and the edge position of the upper silicone roller 7 when pressing down on the photovoltaic module 8. The pressure difference can easily cause the edge position of the photovoltaic module 8 to be damaged by pressure. This can further protect the photovoltaic module 8 and improve the quality of lamination.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
