The laminate is then placed in a laminator for lamination and encapsulation. After lamination, the laminate is removed from the laminator.

[0022] Laminated components typically include a photoelectric conversion functional layer in the middle, PET layers (polyethylene terephthalate) on either side of the photoelectric conversion functional layer, and an adhesive film layer between the photoelectric conversion functional layer and the PET layers. The PET layers can also be replaced with other organic materials. The laminated component needs to be laminated and encapsulated using a laminator. In existing laminators, the laminator heats and pressurizes the laminated component, causing the layers to bond together to form a whole. The laminated component is then output from the laminator. When the laminated component is output from the laminator, it is equivalent to being transferred from a high temperature to a low temperature. Because the expansion coefficients of the layers are different, the laminated component is prone to deformation, resulting in unevenness, which affects not only the appearance but also the performance of the product.
[0023] To address one of the aforementioned problems, this application discloses a laminator 100, which, in some embodiments, combines... Figure 1 As shown, the laminator 100 includes an upper chamber 110, a lower chamber 120, a partition layer 130, and a temperature control device 140. The lower chamber 120 is adapted to house the laminate 200. The partition layer 130 is disposed between the upper chamber 110 and the lower chamber 120. The partition layer 130 is adapted to deform toward the lower chamber 120 to contact the laminate 200 and apply pressure to the laminate 200. The temperature control device 140 is adapted to heat the laminate 200 when the partition layer 130 applies pressure to the laminate 200, and is also adapted to cool the laminate 200 when the partition layer 130 applies pressure to the laminate 200.
[0024] In this embodiment, the laminator 100 can both heat and cool the laminate 200, so that the processing of the laminate 200 can be completed in the same chamber, realizing one-stop preparation, which helps to shorten the length of the production line and reduce the space occupied. Furthermore, the cooling of the laminate 200 is carried out while the laminate 200 is still under pressure, which can suppress the deformation of the laminate 200 due to cooling.
[0025] Specifically, the laminator 100 in this embodiment includes an upper chamber 110, a lower chamber 120, a partition layer 130, and a temperature control device 140. The upper chamber 110 can be inflated and deflated, and the lower chamber 120 can also be inflated and deflated. Inflating can be achieved by an air pump, and deflating can be achieved by a vacuum pump. The partition layer 130 is disposed between the upper chamber 110 and the lower chamber 120, which effectively separates the inner cavity of the laminator 100 into the upper chamber 110 and the lower chamber 120. Due to the pressure difference between the upper chamber 110 and the lower chamber 120, the partition layer 130 can deform under the action of the pressure difference. For example, the material of the partition layer 130 can be silicone, rubber, or other materials that can achieve elastic deformation. When the air pressure in the upper chamber 110 is greater than the air pressure in the lower chamber 120, the partition layer 130 deforms toward the lower chamber 120, thus gradually increasing the space of the upper chamber 110 and gradually decreasing the space of the lower chamber 120. When the air pressure in the upper chamber 110 is less than the air pressure in the lower chamber 120, the partition layer 130 deforms toward the upper chamber 110, thus gradually decreasing the space of the upper chamber 110 and gradually increasing the space of the lower chamber 120.
[0026] Based on the premise that the laminator 100 includes an upper chamber 110, a lower chamber 120, and a separator layer 130, the laminator 100 also includes a temperature control device 140, which is used to heat and cool the laminate 200. The heating and cooling of the temperature control device 140 are performed sequentially, specifically as follows: When the separator 130 applies pressure to the laminate 200, the temperature control device 140 heats the laminate 200, thereby causing the layers of material in the laminate 200 to bond together to form a whole. For example, when the laminate 200 is placed in the lower chamber 120, and the air pressure in the upper chamber 110 is controlled to be greater than the air pressure in the lower chamber 120, the separator 130 deforms towards the lower chamber 120 under the action of the pressure difference until the separator 130 contacts the laminate 200 and applies pressure to the laminate 200. The adhesive film layer in the laminate 200 melts due to the heating by the temperature control device 140, thereby causing the layers of material in the laminate 200 to bond together to form a whole.
[0027] After the layers of material in the laminate 200 are bonded together to form a whole, the temperature control device 140 stops heating the laminate 200 and switches to cooling the laminate 200. During this process, the partition layer 130 maintains pressure on the laminate 200, that is, the air pressure in the upper chamber 110 is greater than the air pressure in the lower chamber 120. Based on this, during the cooling process of the laminate 200, although the expansion coefficients of the layers of material in the laminate 200 are different, due to the pressure of the partition layer 130, each area of the laminate 200 is cooled under pressure. This can suppress the deformation of the laminate 200 caused by cooling, making the product flatter and ensuring performance.
[0028] By heating and cooling the laminate 200 through the temperature control device 140, the processing of the laminate 200 can be completed in the same chamber. This is equivalent to the raw materials being input into the laminator 100 and the laminator 100 outputting the finished product, realizing one-stop preparation, which helps to shorten the length of the production line and effectively reduce the occupation of space.
[0029] In some embodiments, the temperature control device 140 includes a heating plate 143, a heater 141, and a cooler 142. The heater 141 is adapted to heat the heating plate 143 to heat the laminate 200, and the cooler 142 is adapted to cool the heating plate 143 to cool the laminate 200. The heater 141 can heat the heating plate 143 in various ways, as long as heat can be transferred to the heating plate 143. The cooler 142 can also cool the heating plate 143 in various ways, as long as it can absorb the heat from the heating plate 143. This can be either direct or indirect heat transfer.
[0030] Specifically, in some embodiments, combined with Figures 1 to 3 As shown, the temperature control device 140 includes a heating plate 143, a heater 141, and a cooler 142. The heater 141 is adapted to provide a heat medium. The heater 141 and the heating plate 143 are connected so that the heat medium can circulate between the heater 141 and the heating plate 143. The heat medium is adapted to dissipate heat when flowing through the heating plate 143 to heat the laminate 200. The cooler 142 is adapted to provide a cold medium. The cooler 142 and the heating plate 143 are connected so that the cold medium can circulate between the cooler 142 and the heating plate 143. The cold medium is adapted to absorb heat when flowing through the heating plate 143 to cool the laminate 200.
[0031] In this embodiment, cold and hot are relative terms. The heater 141 is a component that provides a heat medium and heats the laminate 200 through that heat medium. The heater 141 includes, but is not limited to, boilers, oil heaters, and fan heaters. When the heater 141 is a boiler, the heat medium it provides is steam or water; when it is an oil heater, the heat medium it provides is oil; and when it is a fan heater, the heat medium it provides is air. The cooler 142 is a component that provides a cold medium and cools the laminate 200 through that cold medium. The cooler 142 includes, but is not limited to, chillers and cooling towers, and the cold medium it provides is water. The types of heaters 141 and coolers 142 can also be selected according to actual operating conditions.
[0032] A circulating flow path for the heating medium is formed between heater 141 and heating plate 143. Heater 141, from which the heating medium flows, has a higher temperature (relative to the current state of the laminate 200). When the heating medium flows through heating plate 143, it dissipates heat, and the heat is transferred to heating plate 143, thus heating it. The heat is then transferred from heating plate 143 to the laminate 200, thereby heating the laminate 200. After losing heat, the heating medium flows back to heater 141 to be reheated, and this cycle repeats. It is understood that heater 141 may have its own temperature control or be temperature-controlled.
[0033] A circulating flow path for the cooling medium is formed between the cooler 142 and the heating plate 143. The cooling medium exiting the cooler 142 has a lower temperature (relative to the current state of the laminate 200). When the cooling medium flows through the heating plate 143, it absorbs heat, and the heat from the heating plate 143 is transferred to the cooling medium, thus cooling it. Similarly, the heat from the laminate 200 is transferred to the heating plate 143 and then to the cooling medium, thus cooling it. After absorbing heat, the cooling medium flows back to the cooler 142 and is cooled again, thus completing the cycle. It is understood that the cooler 142 may have its own temperature control or be temperature-controlled.
[0034] Since the temperature control device 140 heats and then cools the laminate 200, that is, the heater 141 first forms a hot medium circulation with the heating plate 143, and the cooler 142 then forms a cold medium circulation with the heating plate 143.
[0035] The number of coolers 142 can be one, and cooling is achieved through one cooler 142. Furthermore, in some embodiments, combined with... Figure 1 and Figure 3 As shown, there are multiple coolers 142, which are connected in parallel and are respectively connected to the heating plate 143. The temperature of the cold medium provided by each cooler 142 is different, so as to form a cooling gradient on the laminate 200.
[0036] In this embodiment, the number of coolers 142 is multiple, meaning two or more, and can be two, three, four or more. Figure 1 and Figure 3The laminator 100 shown has two coolers 142. Multiple coolers 142 are connected in parallel and each is connected to a heating plate 143, creating a cooling medium circulation between each cooler 142 and the heating plate 143. The cooling medium provided by each cooler 142 has a different temperature, thus creating a cooling gradient on the laminate 200. That is, the cooling medium provided by each cooler 142 flows through the heating plate 143 from high to low temperature, achieving gradual cooling of the laminate 200, preventing cracking, and ensuring uniform shrinkage of each layer of the laminate 200. This helps reduce interfacial shear stress, protects the adhesive film layer of the laminate 200, and, in conjunction with the pressure applied by the separator layer 130, further prevents deformation of the laminate 200. It is understood that the required number of coolers 142 can be selected according to the program design and actual needs.
[0037] For example, the cooling medium temperature of the first refrigerator 142 is 100℃, the cooling medium temperature of the second refrigerator 142 is 90℃, and so on, until the cooling temperature of the nth refrigerator 142 is 20℃. The first refrigerator 142 first forms a cooling medium circulation with the heating plate 143 and runs for a period of time, then the second refrigerator 142 forms a cooling medium circulation with the heating plate 143 and runs for a period of time, until the nth refrigerator 142 forms a cooling medium circulation with the heating plate 143 and runs for a period of time.
[0038] The cooling gradient is formed by multiple coolers 142 providing cold media at different temperatures. The cooling of multiple coolers 142 is independent of each other, which makes the control of the cooling gradient more precise and can respond quickly.
[0039] It is understandable that valves for controlling the flow path are provided in the flow path between each cooler 142 and heating plate 143. By controlling the flow path through the valves, a cold medium circulation is formed between the corresponding cooler 142 and heating plate 143.
[0040] For example, the cooler 142 discharges the cold medium through its discharge end and recovers the cold medium through its recovery end. Valves are installed in the flow path between the discharge end of each cooler 142 and the heating plate 143, and valves are also installed in the flow path between the recovery end of each cooler 142 and the heating plate 143. Taking a number of coolers 142 as an example, the valve between the first cooler 142 and the heating plate 143 is open, while the valves between the remaining coolers 142 and the heating plate 143 are closed. This allows a cold medium circulation between the first cooler 142 and the heating plate 143, and so on. Those skilled in the art will understand that the flow path control via valves can be designed according to actual operating conditions, and parallel coolers 142 can also achieve flow path opening and closing by sharing a multi-way valve.
[0041] The number of heaters 141 can be one, and heating is achieved through a single heater 141. Furthermore, in some embodiments, combined with... Figure 1 and Figure 2 As shown, there are multiple heaters 141, which are connected in parallel and connected to the heating plate 143 respectively. The temperature of the heat medium provided by each heater 141 is different, so as to form a temperature gradient on the laminate 200.
[0042] In this embodiment, the number of heaters 141 is multiple, meaning two or more, and can be two, three, four or more. Figure 1 and Figure 2 The laminator 100 shown has two heaters 141. Multiple heaters 141 are connected in parallel and each is connected to a heating plate 143, creating a heat medium circulation between each heater 141 and the heating plate 143. The heat medium supplied by each heater 141 has a different temperature, thus creating a temperature gradient on the laminate 200. That is, the heat medium supplied by each heater 141 flows through the heating plate 143 from low to high temperature, achieving gradual heating of the laminate 200. This results in more uniform heating of the laminate 200, preventing internal pressure from rising and causing structural damage, thereby further suppressing deformation of the laminate 200. It is understood that the required number of heaters 141 can be selected according to the program design and actual needs.
[0043] For example, the heat medium temperature of the first heater 141 is 50°C, the heat medium temperature of the second heater 141 is 60°C, ... the heat medium temperature of the nth heater 141 is 200°C. The first heater 141 first forms a heat medium circulation with the heating plate 143 and runs for a period of time, then the second heater 141 forms a heat medium circulation with the heating plate 143 and runs for a period of time, until the nth heater 141 forms a heat medium circulation with the heating plate 143 and runs for a period of time.
[0044] The temperature gradient is formed by multiple heaters 141 providing heat mediums at different temperatures. The heating of the multiple heaters 141 is independent of each other, which makes the control of the temperature gradient more precise and the response faster.
[0045] It is understood that valves for controlling the opening and closing of the flow path are provided in the flow path between each heater 141 and heating plate 143. By controlling the opening and closing of the corresponding flow path through the valves, a heat medium circulation is formed between the corresponding heater 141 and heating plate 143.
[0046] For example, heater 141 discharges heat medium through its discharge end and recovers heat medium through its recovery end. Valves are installed in the flow path between the discharge end of each heater 141 and the heating plate 143, and valves are also installed in the flow path between the recovery end of each heater 141 and the heating plate 143. Taking a number of heaters 141 as n, the valve between the first heater 141 and the heating plate 143 is open, while the valves between the remaining heaters 141 and the heating plate 143 are closed, thus forming a heat medium circulation between the first heater 141 and the heating plate 143, and so on. Those skilled in the art will understand that the flow path control via valves can be designed according to actual working conditions, and parallel heaters 141 can also achieve flow path on / off control through a shared multi-way valve.
[0047] As can be seen from the above, a hot medium circulation can be formed between the heater 141 and the heating plate 143, and a cold medium circulation can be formed between the cooler 142 and the heating plate 143. Therefore, the heating plate 143 can be provided with a flow channel for the flow of the hot medium circulation and a flow channel for the flow of the cold medium circulation. However, under the premise that the size and specifications of the heating plate 143 remain unchanged, the heat dissipation area and heat absorption area of the heating plate 143 are relatively small.
[0048] Therefore, in some embodiments, the heating plate 143 is provided with a medium flow channel (not shown in the figure), and the heater 141 and the cooler 142 share the medium flow channel. The hot medium is adapted to dissipate heat when flowing through the medium flow channel, and the cold medium is adapted to absorb heat when flowing through the medium flow channel. That is, when the laminate 200 needs to be heated, the hot medium output from the heater 141 flows to the heating plate 143 and returns to the heater 141 after flowing through the medium flow channel. When the laminate 200 needs to be cooled (at which time heating stops), the cold medium output from the cooler 142 flows to the heating plate 143 and returns to the cooler 142 after flowing through the aforementioned medium flow channel. By having the heater 141 and the cooler 142 share the medium flow channel, it helps to increase the heat dissipation area and heat absorption area of the heating plate 143.
[0049] It is understandable that since the heater 141 and the cooler 142 share a medium flow channel, the opening and closing of the corresponding flow channels can be controlled by setting valves in the flow path between the heater 141 and the medium flow channel and in the flow path between the cooler 142 and the medium flow channel, thereby making it possible for the heater 141 and the cooler 142 to share a medium flow channel.
[0050] For example, valves are installed on the flow paths between the discharge and recovery ends of heater 141 and the medium flow path, respectively, and valves are installed on the flow paths between the discharge and recovery ends of cooler 142 and the heating plate 143, respectively. When the laminate 200 needs to be heated, the valves on the flow paths between the discharge and recovery ends of heater 141 and the heating plate 143 are opened, and the valves on the flow paths between the discharge and recovery ends of cooler 142 and the heating plate 143 are closed. The hot medium flows out from the discharge end of heater 141, flows through the medium flow path, and returns to heater 141 from the recovery end of heater 141, completing the hot medium circulation. When the laminate 200 needs to be cooled, the valves on the flow paths between the discharge and recovery ends of heater 141 and the heating plate 143 are closed, and the valves on the flow paths between the discharge and recovery ends of cooler 142 and the heating plate 143 are opened. The cold medium flows out from the discharge end of cooler 142, flows through the medium flow path, and returns to cooler 142 from the recovery end of cooler 142, completing the cold medium circulation. Those skilled in the art will understand that the flow path can be controlled by valves according to the actual working conditions.
[0051] In some embodiments, combined with Figure 4 As shown, the temperature control device 140 includes a heating plate 143, a heater 141, and a cooler 142. The heater 141 is adapted to generate heat when energized, and at least a portion of the heater 141 is embedded in the heating plate 143. The cooler 142 is adapted to provide a cooling medium. The cooler 142 and the heating plate 143 are connected so that the cooling medium can circulate between the cooler 142 and the heating plate 143. The cooling medium is adapted to absorb heat when flowing through the heating plate 143 to cool the laminate 200. This embodiment is similar to the previous embodiment, except that the heater 141 in this embodiment generates heat by energizing, thereby heating the heating plate 143, rather than heating the heating plate 143 based on a heat medium.
[0052] In some embodiments, the temperature control device 140 is a heat pump, and the heating plate 143 is adapted to allow refrigerant to flow through it so as to dissipate heat and absorb heat. That is, the heating plate 143 has both the function of dissipating heat when the refrigerant flows through it and the function of absorbing heat when the refrigerant flows through it. Thus, the heating plate 143 can be either a condenser or an evaporator.
[0053] For example, the refrigerant in the heat pump is adapted to dissipate heat when circulating in a first direction and flowing through the heating plate 143 to heat the laminate 200, and the refrigerant in the heat pump is adapted to absorb heat when circulating in a second direction opposite to the first direction and flowing through the heating plate 143 to cool the laminate 200. The heating plate 143 constitutes part of the heat pump. When heating the laminate 200 is required, the heating plate 143 acts as a condenser; when cooling the laminate 200 is required, the heating plate 143 acts as an evaporator. By configuring the heat pump, energy consumption can be reduced.
[0054] In some embodiments, combined with Figure 1 As shown, the heating plate 143 is adapted to support the laminate 200. Since the temperature control device 140 dissipates and absorbs heat through the heating plate 143, placing the laminate 200 on the heating plate 143 not only enables the heating plate 143 to support the laminate 200, but also improves the heat transfer efficiency between the heating plate 143 and the laminate 200.
[0055] In some embodiments, combined with Figure 1 As shown, at least a portion of the cavity wall of the lower chamber 120 is formed by a heating plate 143. Thus, the heating plate 143 can not only heat and cool the laminate 200, but also heat and cool the lower chamber 120. Since the laminate 200 is placed in the lower chamber 120, this allows for more uniform heat transfer between the heating plate 143 and the laminate, resulting in a more uniform temperature distribution within the laminate 200, which is more conducive to suppressing deformation.
[0056] In some embodiments, combined with Figure 1 As shown, at least a portion of the cavity wall of the upper chamber 110 is formed by a heating plate 143. For example, the bottom of the lower chamber 120 is formed by a heating plate 143 (defined as the lower heating plate), and the top of the upper chamber 110 is formed by a heating plate 143 (defined as the upper heating plate). The laminate 200 is placed in the lower chamber 120 and placed on the lower heating plate. The upper heating plate can achieve temperature control of the upper chamber, and the lower heating plate can achieve temperature control of the lower chamber 120, avoiding a large temperature difference between the upper chamber 110 and the lower chamber 120. When there are process requirements, the temperature difference can be easily adjusted, thereby making the temperature control of the laminate 200 more precise and achieving more uniform heat transfer to the laminate 200.
[0057] It is understandable that the operation of the laminator 100 is based on a control system, such as a PLC control system. The control system controls the air pressure of the upper chamber 110 and the lower chamber 120, controls the heating and cooling of the laminator 200 by the temperature control device 140, and controls the opening and closing of the corresponding valves, etc., to ensure the normal operation of the laminator 100.
