Description

Technical Field

[0001] This utility model belongs to the field of laminating machine technology, and more specifically, relates to a double-sided oil-heated semi-automatic laminating machine. Background Technology

[0002] The photovoltaic (PV) power generation industry is developing rapidly, with PV modules applied in various fields. To meet different operating conditions, double-glass and triple-glass PV modules have been introduced, and the thickness of PV modules is gradually increasing. The thicker the PV module, the higher the required heating rate, temperature uniformity, and temperature control accuracy in the lamination process. Existing laminators suffer from uneven heat conduction due to gaps between the electric heater and the heating plate. Therefore, a laminator capable of uniform heating and stable temperature control is needed.

[0003] To meet the needs of small-batch trial production and manufacturing of various products during the R&D phase, this solution introduces a double-sided oil-heated semi-automatic laminator. Both the upper and lower heating plates in this solution are oil-heated, resulting in faster heating within the cavity, higher temperature uniformity, and more precise temperature control. This provides a more ideal experimental environment for photovoltaic cell module lamination, while also offering low investment costs. Utility Model Content

[0029] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0030] like Figure 1-3 As shown, a double-sided oil-heated semi-automatic laminator includes:

[0031] The upper heating plate 1 and the lower heating plate 2 can move closer to each other and further apart through a driving mechanism.

[0032] The dual-core heating furnace 3 has an upper heating plate 1 and a lower heating plate 2 respectively provided with an upper heating chamber and a lower heating chamber. The two heating cores of the dual-core heating furnace 3 independently heat the upper heating chamber and the lower heating chamber. Heating oil circulates between the upper heating chamber and the lower heating chamber and the dual-core heating furnace 3.

[0033] Specifically, the temperature of the upper heating plate 1 and the lower heating plate 2 are independently heated and controlled by the dual-core heating furnace 3, which improves the temperature control during lamination and is suitable for use with photovoltaic cell modules 12 with different numbers of layers. At the same time, the heating oil as a heat medium makes the heating of the upper heating plate 1 and the lower heating plate 2 more uniform, and the specific heat value of the heating oil also makes the temperature control more stable, thereby making the temperature uniformity and temperature control accuracy of the lamination operation higher.

[0034] Furthermore, an insulation layer is provided on the outer periphery of the upper heating plate 1 and the lower heating plate 2 to enhance the insulation of the upper heating plate 1 and the lower heating plate 2 and reduce heat loss; the upper heating chamber and the lower heating chamber are connected to the dual-core heating furnace through the insulation pipe 11 to circulate the heating oil.

[0035] In this embodiment, a groove and a pressure strip frame 4 are provided on the side of the upper heating plate 1 near the lower heating plate 2. The pressure strip frame 4 is located between the upper heating plate 1 and the lower heating plate 2 and is outside the groove. An elastic diaphragm plate 5 is provided on the opening side of the groove. The elastic diaphragm plate 5 closes the groove and forms an upper chamber structure inside the groove. When the upper heating plate 1 is close to the lower heating plate 2, the elastic diaphragm plate 5, the pressure strip frame 4 and the lower heating plate 2 form a sealed lower chamber structure. The lower chamber structure is used to accommodate the photovoltaic cell module.

[0036] Vacuum pump 6 is connected to the upper chamber structure and the lower chamber structure respectively.

[0037] Specifically, the photovoltaic cell module 12 is placed inside the lower chamber structure. A vacuum is created inside the lower chamber structure, causing the elastic film plate 5 to compress the photovoltaic cell module 12 within the lower chamber structure. Simultaneously, the upper heating plate 1 and the lower heating plate 2 are heated together, facilitating rapid heating of both the upper and lower chamber structures. After lamination, a vacuum is created in the upper chamber structure, moving the elastic film plate 5 away from the lower heating plate 2, facilitating the lamination of the next photovoltaic cell module 12.

[0038] Furthermore, conformal sealing strips 13 are respectively provided between the pressure strip frame 4 and the upper heating plate 1 and the lower heating plate 2.

[0039] In this embodiment, the elastic diaphragm 5 is a silicone plate.

[0040] In this embodiment, the vacuum pump 6 is connected to the upper chamber structure and the lower chamber structure via a pipeline and two pneumatic butterfly valves 7, respectively.

[0041] Specifically, the vacuum state of the upper and lower chamber structures is independently controlled by two pneumatic butterfly valves 7.

[0042] In this embodiment, the lower heating plate 2 is mounted on the bracket, and the driving mechanism includes:

[0043] Cylinder 8 is located at the lower end of the bracket;

[0044] Lever 9, the pivot point of lever 9 is set on the side wall of the bracket, the lower end of lever 9 is connected to the telescopic end of cylinder 8, and the upper end of lever 9 is connected to the upper heating plate 1. Cylinder 8 drives lever 9 to move, thereby making the upper heating plate 1 move closer to and further away from the lower heating plate 2.

[0045] Specifically, cylinder 8 drives the upper heating plate 1 to move closer to and further away from the lower heating plate 2 via a lever structure.

[0046] In this embodiment, a controller 10 is also included. The controller 10 is equipped with a human-machine interface panel and is connected to the vacuum pump 6, the dual-core heating furnace 3 and the drive mechanism.

[0047] Specifically, the controller 10 adjusts various parameters and controls the operation of the laminator.

[0048] In this embodiment, the dual-core heating furnace 3 is an electrically heated organic heat carrier furnace, which is connected to the upper heating plate 1 and the lower heating plate 2 via a connecting hose.

[0049] In this embodiment, the thickness of the lower chamber is the same as the thickness of the pressure strip frame 4, and the pressure strip frame 4 is detachably connected to the upper heating plate 1.

[0050] Specifically, the pressure strip frame 4 is attached to the upper heating plate 1 by means of a limiting hook or bolt assembly, and the pressure strip frame 4 of different thicknesses can be adjusted to adapt to the processing of photovoltaic cell modules 12 with different layers / thicknesses.

[0051] In this embodiment, a slope of a guide elastic film plate 5 is provided on the inner periphery of the pressure strip frame 4 near the upper heating plate 1. When the elastic film plate 5 approaches the photovoltaic cell module 12, the slope causes the elastic film plate 5 to press down on the photovoltaic cell module 12 to form a guide.

[0052] Specifically, the deformation of the elastic membrane 5 is restricted by the slope, thereby causing the elastic membrane 5 to preferentially press the stacked photovoltaic cell module 12 downward.

[0053] In this embodiment, a notch is provided on the inner periphery of the pressure strip frame 4 near the lower heating plate 2, and the vacuum port of the lower chamber structure is provided at intervals below the pressure strip frame 4 and communicates with the notch.

[0054] Specifically, the slope is used to block the elastic membrane 5, preventing the elastic membrane 5 from being blocked by suction and thus affecting the compression of the photovoltaic cell module 12.

[0055] This embodiment describes the use of a double-sided oil-heated semi-automatic laminator, taking the use of a double-layer photovoltaic cell module as an example:

[0056] The controller 10 controls the dual-core heating furnace 3 to independently heat the upper heating plate 1 and the lower heating plate 2. When the upper and lower chamber structures reach the predetermined temperature, the drive mechanism opens the upper heating plate 1, then places the double-layer photovoltaic cell module 12 into the lower heating chamber, and then lowers and resets the upper heating plate 1. Afterwards, the lower chamber structure is evacuated, causing the silicone plate to elastically deform and compress the double-layer photovoltaic cell module 12 under atmospheric pressure, thereby ensuring a tight bond between the double-layer photovoltaic cell module 12 and completing the lamination process.

[0057] Afterwards, the vacuum in the lower chamber is broken, and the upper heating plate 1 is opened again to remove and replace the double-layer photovoltaic cell module 12. At the same time, the upper chamber structure is evacuated to reset the silicone plate, preventing the silicone plate from falling freely and contacting the photovoltaic cell module 12 that will be replaced later.

[0058] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
