[0002] In the photovoltaic industry, laminated sheets include stacked front glass, front film, photovoltaic cells, back film and backboard. During the manufacturing process, the laminated sheets need to be laminated and fixed by a laminator to make a laminated part, that is, the front glass, front film, photovoltaic cells, back film and backboard are bonded together at high temperature.

[0003] Typically, a laminator includes an upper press and a lower press. The lower press is used to place the laminated sheets, and the upper press includes a flexible laminate. During the lamination process, the flexible laminate abuts against the laminated sheets, and the flexible laminate undergoes elastic deformation along the height direction of the laminator. The deformation of the flexible laminate achieves lamination and fixation of the laminated sheets.

[0004] However, during the lamination and fixing process, the frequent deformation of the flexible laminate makes the flexible laminate easily damaged, thereby reducing the life of the laminator.

[0027] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0030] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0031] In the field of solar power generation technology, the main body used to achieve photoelectric conversion is the photovoltaic module. During the manufacturing process of the photovoltaic module, the laminated sheets need to be laminated and fixed by a laminating machine to form a laminated part. Figure 1 This is an exploded view of the laminate provided in this application in one embodiment. Figure 1 As shown, the laminated sheet 100 includes a front glass 101 , a front adhesive film 102 , a photovoltaic cell 103 , a back adhesive film 104 and a back sheet 105 that are stacked.

[0032] The front glass 101 may be made of a rigid material such as tempered glass, PET (Polyethylene Terephthalate), or PC (Polycarbonate).

[0033] Alternatively, the material of the front glass 101 may be one of flexible materials such as PVF (Polyvinyl Fluoride), ETFE (Ethylene-Tetra-Fluoro-Ethylene), and PVDF (Polyvinylidene Fluoride).

[0034] The back plate 105 may be made of a rigid material such as tempered glass, PET (Polyethylene Terephthalate), or PC (Polycarbonate).

[0035] Alternatively, the material of the back plate 105 may be one of flexible materials such as PVF (Polyvinyl Fluoride), ETFE (Ethylene-Tetra-Fluoro-Ethylene), and PVDF (Polyvinylidene Fluoride).

[0036] The materials of the front glass 101 and the back plate 105 can be the same or different.

[0037] The front adhesive film 102 is located between the front glass 101 and the photovoltaic cell 103 . The front adhesive film 102 is used to connect and fix the photovoltaic cell 103 to the front glass 101 .

[0038] The material of the front film 102 can be one of polyolefins such as EVA (Ethylene-Vinyl Acetate Copolymer), POE (Polyolefin Elastomer), PVB (Polyvinyl Butyral), etc. The above materials have high light transmittance, which is beneficial to improving the photoelectric conversion efficiency of photovoltaic modules.

[0039] The front adhesive film 102 may also be an EPE adhesive film (EVA-POE-EVA co-extruded structure) or an EP adhesive film (EVA-POE co-extruded structure).

[0040] The back adhesive film 104 is located between the back plate 105 and the photovoltaic cell 103 . The back adhesive film 104 is used to achieve a connection and fixation between the photovoltaic cell 103 and the back plate 105 .

[0041] The material of the back film 104 can be one of polyolefins such as EVA (Ethylene-Vinyl Acetate Copolymer), POE (Polyolefin Elastomer), PVB (Polyvinyl Butyral), etc. The above materials have high light transmittance, which is beneficial to improving the photoelectric conversion efficiency of photovoltaic modules.

[0042] The back film 104 may also be an EPE film (EVA-POE-EVA co-extruded structure) or an EP film (EVA-POE co-extruded structure).

[0043] The types of photovoltaic cells 103 include, but are not limited to, Passivated Emitter Rear Cell (PERC), Tunnel Oxide Passivated Contact (TOPCon), Heterojunction with Intrinsic Thin-film (HJT), Interdigitated Back Contact (IBC), perovskite cells, etc.

[0044] A PERC cell, along its thickness, consists of a front surface silver electrode, a front surface silicon nitride passivation layer, a phosphorus emitter layer, a P-type silicon substrate layer, a local aluminum back field, a metal aluminum back electrode, and a back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back surface, replacing the all-aluminum back field. This enhances internal back reflection of light from the silicon substrate, reduces the back recombination rate, and increases cell efficiency by 0.5%-1%.

[0045] A TOPCon cell, along its thickness, consists of a silver electrode, a front silicon nitride passivation layer, a boron-doped emitter, an N-type base silicon layer, a diffused doped layer, an ultrathin silicon oxide layer, doped polysilicon, silicon nitride, and a silver electrode. The back of the cell consists of an ultrathin silicon oxide layer (1nm to 2nm) and a phosphorus-doped microcrystalline amorphous hybrid silicon thin film, which together form a passivated contact structure. This structure blocks minority carrier-hole recombination, improving the cell's open-circuit voltage and short-circuit current. The ultrathin oxide layer allows majority electrons to tunnel into the polysilicon layer while blocking minority carrier-hole recombination. The excellent passivation effect of the ultrathin silicon oxide and heavily doped silicon film causes surface band bending of the silicon wafer, creating a field passivation effect. This significantly increases the probability of electron tunneling and reduces contact resistance, thereby increasing the cell's open-circuit voltage and short-circuit current, and thus improving the cell's conversion efficiency.

[0046] For HJT cells, along their thickness direction, the HJT cells include a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type base silicon layer, an intrinsic amorphous silicon film, a P-type amorphous silicon film, a back conductive film, and a back low-temperature silver electrode.

[0047] An IBC cell, along its thickness, consists of a silicon nitride inversion layer, an N+ front surface field, an N-type base silicon layer, a P+ emitter, an N+ back field, an aluminum oxide passivation layer, a silicon nitride anti-reflection layer, and a metallic silver electrode. IBC cells utilize ion implantation technology to achieve P and N regions with excellent uniformity and precisely controllable junction depth. The front of the cell is free of grid lines, eliminating current losses from metal electrode shading and maximizing the utilization of incident photons. This improves short-circuit current by approximately 7% compared to conventional solar cells. Due to the back-contact structure, grid line shading is not a concern, allowing for a wider grid line ratio, reducing series resistance and achieving a high fill factor. Surface passivation and surface light trapping structures can be optimized, resulting in a lower front-surface recombination rate and surface reflection.

[0048] A perovskite cell, along its thickness, consists of a substrate material, a conductive film, an electron transport layer (titanium dioxide), a perovskite absorption layer (hole transport layer), and a metal cathode. Perovskite materials have a high light absorption coefficient and a long carrier diffusion distance. Photons absorbed by the perovskite material are converted into electrons, which are easily collected by the electrode with minimal loss. This results in high photogenerated voltage and current, leading to high photoelectric conversion efficiency.

[0049] The embodiment of the present application does not impose any special limitation on the specific type of the photovoltaic cell 103 .

[0050] Based on the above-mentioned laminated sheets 100 , an embodiment of the present application provides a laminating machine, which laminates and fixes the laminated sheets 100 to produce a laminated part.

[0051] In one embodiment, if Figure 2 As shown, the laminator includes an upper press 1 and a lower press 2 distributed along its own height direction Z. The lower press 2 is used to place the laminated stack 100. The upper press 1 includes a flexible pressing plate 200. During the lamination process, the flexible pressing plate 200 can elastically deform along the height direction Z of the laminator and abut against the laminated stack 100, thereby achieving lamination and fixation of the laminated stack 100.

[0052] However, the frequent deformation of the flexible pressing plate 200 makes the flexible pressing plate 200 easily damaged, thereby reducing the life of the laminator.

[0053] In view of this, the present application provides a laminator with a longer service life in another embodiment.

[0054] like Figure 3 As shown, the laminating machine provided in the embodiment of the present application includes an upper press 1 and a lower press 2 arranged along its own height direction Z, and the lower press 2 is used to place the laminated stack 100.

[0055] The upper press 1 comprises a body 11 and a pressing plate 12, which is sealed to the body 11 to form a first sealed cavity 10. The upper press 1 has a heating device, which can heat the upper press 1 when the pressing plate 12 is laminating and fixing the laminate 100.

[0056] The laminator also includes a first control component 3, which is connected to the first sealed cavity 10. The first control component 3 is used to adjust the pressure in the first sealed cavity 10 so that the pressing plate 12 moves along the height direction Z of the laminator toward the direction close to the lower press 2. The pressing plate 12 can abut against the laminated stack 100 so that the laminated stack 100 is laminated and fixed.

[0057] The first control component 3 may be a vacuum pump. The first sealed cavity 10 is connected to the vacuum pump, which can inflate the first sealed cavity 10 to increase the amount of gas and pressure in the first sealed cavity 10, thereby increasing the pressure difference on both sides of the pressing plate 12 in the height direction Z. Under the action of the pressure difference, the pressing plate 12 moves downward in the height direction Z until it abuts against the laminated stack 100. Thereafter, the pressing plate 12 continues to apply pressure to the laminated stack 100 under the action of the pressure difference, thereby achieving the lamination and fixation of the laminated stack 100 by the pressing plate 12.

[0058] like Figure 3 As shown, the laminator also includes a first driving module 4, which is installed on the main body 11 and connected to the pressing plate 12. The first driving module 4 is used to drive the pressing plate 12 to move along the height direction Z of the laminator in a direction away from the laminated stack 100, so as to facilitate placing the laminated stack 100 on the lower press 2 and facilitate removing the laminated parts from the lower press 2.

[0059] Specifically, such as Figure 4 As shown, the first driving module 4 is mounted on the body 11 and connected to the pressing plate 12. The first driving module 4 is used to drive the pressing plate 12 to move upward along the height direction Z of the laminator. In other embodiments, the first driving module 4 can also be used to drive the pressing plate 12 to move in other directions. The specific driving direction of the first driving module 4 is not limited in this application.

[0060] In addition, in the laminating machine, the pressing plate 12 can be a hard plate, and the material of the hard plate includes but is not limited to carbon structural steel (such as Q235), alloy structural steel (such as 45 steel, Cr12), stainless steel (such as 304, 316), aluminum alloy (such as 6061, 7075) and other metal materials.

[0061] Alternatively, the material of the hard pressing plate 12 includes but is not limited to ceramic materials (such as alumina ceramics, silicon nitride ceramics), high-temperature resistant composite materials (such as carbon fiber reinforced resin-based composite materials), polytetrafluoroethylene plates (such as PTFE, Teflon) and other non-metallic materials.

[0062] Alternatively, the material of the hard pressing plate 12 includes but is not limited to composite structural materials such as metal-ceramic composite plates and metal-Teflon coating plates.

[0063] The embodiment of the present application does not limit the specific material of the pressing plate 12.

[0064] In the present application, the lamination and fixation of the laminated stack 100 by the press plate 12 is achieved by the movement of the hard press plate 12 along the height direction Z, so that the press plate 12 applies a uniform force to the surface of the laminated stack 100, reducing the risk of damage to the press plate 12 due to frequent deformation, extending the service life of the press plate 12, and improving the working stability of the press plate 12.

[0065] In the first embodiment, the specific structure of the first driving module 4 can be as follows: Figure 5 As shown, the first driving module 4 includes an elastic member 42 and a push rod 41 . The push rod 41 is movably connected to the body 11 . One end of the elastic member 42 is connected to the body 11 , and the other end of the elastic member 42 is connected to the push rod 41 .

[0066] Specifically, the body 11 has a mating groove 111 for accommodating the elastic member 42. When the first control member 3 drives the pressing plate 12 to move downward in the height direction Z of the laminator, the pressing plate 12 drives the push rod 41 to move downward in the height direction Z of the laminator, and the elastic member 42 is compressed. When the pressure difference on both sides of the pressing plate 12 decreases, the elastic member 42 extends under the action of its own rebound force, so that the elastic member 42 drives the push rod 41 to move upward in the height direction Z of the laminator. In other words, the pressing plate 12 can achieve upward movement in the height direction Z of the laminator through the rebound reset of the elastic member 42.

[0067] In the second embodiment, the specific structure of the first driving module 4 can be as follows: Figure 6 As shown, the first driving module 4 can be a hydraulic cylinder or a pneumatic cylinder.

[0068] The first driving module 4 includes at least a cylinder body 43 and a piston 44. One end of the piston 44 is located in the cylinder body 43 and divides the cylinder body 43 into a first chamber 45 and a second chamber 46. During the operation of the first driving module 4, by injecting a medium into the first chamber 45 and discharging the medium in the second chamber 46, the piston 44 moves toward the outside of the cylinder body 43 under the push of the medium, thereby pushing the pressing plate 12 to move downward along the height direction Z of the laminator.

[0069] Alternatively, during the operation of the first driving module 4, the medium in the first chamber 45 is discharged and the medium is injected into the second chamber 46, so that the piston 44 moves into the cylinder 43 under the push of the medium, thereby canceling the restriction of the first driving module 4 on the pressure plate 12, so that the pressure plate 12 can move upward along the height direction Z of the laminator.

[0070] When the first driving module 4 is a hydraulic cylinder, the medium is liquid. When the first driving module 4 is a pneumatic cylinder, the medium is gas.

[0071] In the third embodiment, the specific structure of the first driving module 4 can be as follows: Figure 7 and Figure 8 As shown, the first driving module 4 can be a motor 47 .

[0072] The motor 47 may be directly connected to the pressing plate 12 or indirectly connected to the pressing plate 12 .

[0073] When the motor 47 is directly connected to the pressing plate 12, as shown in FIG. Figure 7 As shown, the output shaft of the motor 47 is connected to a screw 48, which is threadedly connected to the pressing plate 12. The motor 47 can drive the screw 48 to rotate, and during the rotation of the screw 48, the pressing plate 12 can be driven to move along the height direction Z of the laminator.

[0074] When the motor 47 is indirectly connected to the pressing plate 12, as shown in FIG. Figure 8 As shown, the output shaft of the motor 47 is connected to the screw 48, the screw 48 is threadedly connected to the push rod 41, one end of the push rod 41 is fixedly connected to the pressure plate 12, and the motor 47 can drive the screw 48 to rotate. During the rotation of the screw 48, the push rod 41 can be driven to move along the height direction Z of the laminator, so that the push rod 41 drives the pressure plate 12 to move along the height direction Z of the laminator.

[0075] When the first driving module 4 is a motor 47, the laminator can also be provided with a control system connected to the motor 47. The control system can drive the push rod 41 by controlling the motor 47 to adjust the distance between the main body 11 and the pressing plate 12. The connection between the motor 47 and the control system is a wired connection or a wireless connection so as to realize the data control of the laminator by the control system.

[0076] In the above embodiments, Figure 8 As shown, the number of the first driving module 4 is one. When there is one first driving module 4 , the first driving module 4 is located at the geometric center of the pressing plate 12 .

[0077] Alternatively, there are multiple first driving modules 4 , and the multiple first driving modules 4 are arranged along the first direction X and / or the second direction Y. The first direction X and the second direction Y are both perpendicular to the height direction Z of the laminator.

[0078] Specifically, the plurality of first driving modules 4 may be arranged along the first direction X, the plurality of first driving modules 4 may be arranged along the second direction Y, or the plurality of first driving modules 4 may be arranged along both the first direction X and the second direction Y.

[0079] In this embodiment, if Figure 9 As shown, when there is only one first driving module 4 , the manufacturing cost of the first driving module 4 can be reduced.

[0080] like Figure 10 As shown, when there are four first driving modules 4, the first driving modules 4 are evenly arranged at the four corners of the pressing plate 12, which is beneficial for the first driving module 4 to apply uniform force when driving the pressing plate 12, can reduce the risk of tilting of the pressing plate 12, and improve the lamination quality of the laminator.

[0081] In other embodiments, the specific number of the first driving modules 4 may also be 2, 3, 5 or other values. The present application does not limit the specific number of the first driving modules 4 .

[0082] Furthermore, in this embodiment, the first direction X may be specifically along the length of the platen 12, and the second direction Y may be specifically along the width of the platen 12. In other embodiments, the first direction X and the second direction Y may be other directions perpendicular to the height direction Z of the laminator. For example, the first direction X may be a diagonal direction along the radial direction of the platen 12, and the second direction Y may be another diagonal direction along the radial direction of the platen 12. The present application does not limit the specific directions of the first direction X and the second direction Y.

[0083] like Figure 3 As shown, the upper press 1 further includes a first sealing member 13, and the body 11 and the pressing plate 12 are connected via the first sealing member 13 to enclose a first sealed cavity 10. The first sealing member 13 is made of elastic material.

[0084] Specifically, one end of the first sealing member 13 is connected to the body 11, and the other end of the first sealing member 13 is connected to the pressing plate 12. The first sealing member 13 is distributed in an annular shape along the periphery of the pressing plate 12. The body 11, the first sealing member 13, and the pressing plate 12 together form a sealed first sealed cavity 10. When the laminator drives the pressing plate 12 to move along the height direction Z of the laminator, the pressing plate 12 causes the first sealing member 13 to elastically deform.

[0085] In this embodiment, the first sealing member 13 connects the body 11 and the pressure plate 12 to form the first sealed cavity 10, improving the sealing performance of the first sealed cavity 10 and reducing the risk of air leakage when the first control member 3 adjusts the pressure of the first sealed cavity 10. Furthermore, the elastic material of the first sealing member 13 enables the laminator to compensate for the thermal expansion and deformation of the rigid pressure plate 12 in high-temperature environments, maintaining the laminator's accuracy (e.g., a temperature differential of ±3°C) and improving the lamination efficiency.

[0086] The first sealing member 13 may be made of elastic materials such as silicone rubber, nitrile rubber (NBR), thermoplastic polyurethane (TPU), or special composite materials (such as carbon fiber reinforced elastomer). This application does not limit the specific material of the first sealing member 13.

[0087] like Figure 11 and Figure 12 As shown, the upper press 1 further includes a connecting member 14 , and the first sealing member 13 and the pressing plate 12 are detachably connected via the connecting member 14 .

[0088] In this embodiment, the first sealing member 13 is detachably connected to the pressing plate 12, and can be replaced or updated when a single component is damaged, which is beneficial for users to repair and replace the laminator and increases the service life of the laminator.

[0089] The cross-sectional shape of the connecting member 14 can be an I-shape, a spherical shape or other shapes.

[0090] In some embodiments, as Figure 11 As shown, the connecting member 14 includes a first mounting groove 141 and a second mounting groove 142. The pressure plate 12 is mounted in the first mounting groove 141, and the first sealing member 13 is detachably mounted in the second mounting groove 142. The dimension of the second mounting groove 142 along the thickness direction of the first sealing member 13 is less than or equal to the thickness dimension of the first sealing member 13, thereby improving the connection reliability between the connecting member 14 and the first sealing member 13.

[0091] Figure 11 The cross-sectional shape of the connecting member 14 is shown as an I-shaped. Figure 11 As shown, along the distribution direction of the pressure plate 12 and the first sealing member 13 , illustratively, along the first direction X, the first mounting groove 141 and the second mounting groove 142 are respectively located on both sides of the connecting member 14 .

[0092] The pressing plate 12 and the connecting member 14 may be connected in an irremovable manner by bonding, welding, etc. Alternatively, the pressing plate 12 and the connecting member 14 may be connected in a removable manner.

[0093] In other embodiments, Figure 12As shown, the pressing plate 12 includes a main body 121 and a raised portion 122. The raised portion 122 is located on the side of the main body 121 away from the lower press 2. The connecting member 14 is installed on the raised portion 122 so that a gap is left between the connecting member 14 and the main body 121. The gap is used to accommodate the first sealing member 13, so that the first sealing member 13 is clamped and fixed by the connecting member 14 and the pressing plate 12.

[0094] exist Figure 12 The cross section shown is a flat-plate-shaped connector 14 that is detachably connected to the protrusion 122. Specifically, the connector 14 can completely cover the pressure plate 12, or the connector 14 can be distributed in a strip shape on the pressure plate 12. In other embodiments, the connector 14 can also have other shapes, and this application does not limit the specific shape of the connector 14.

[0095] like Figure 13 and Figure 14 As shown, the main body 11 includes a bracket 112, which is detachably connected to the first seal 13. When the first seal 13 is damaged, the first seal 13 can be replaced and updated, which is beneficial for users to repair and replace the laminator and improve the service life of the laminator.

[0096] In some embodiments, as Figure 13 As shown, the bracket 112 includes a third mounting groove 112a, into which the first seal 13 is removably mounted. The dimension of the third mounting groove 112a along the thickness of the pressing plate 12 is less than or equal to the thickness of the first seal 13, thereby improving the connection reliability between the bracket 112 and the first seal 13. Providing the third mounting groove 112a in the bracket 112 simplifies the manufacturing process and reduces the manufacturing cost of the laminator.

[0097] Or, in other embodiments, Figure 14 As shown, the bracket 112 includes a first supporting portion 112b and a second supporting portion 112c, the first supporting portion 112b is connected to the second supporting portion 112c, and the first sealing member 13 is clamped and fixed by the first supporting portion 112b and the second supporting portion 112c.

[0098] The first support portion 112b and the second support portion 112c can be detachably connected by fasteners, and the fasteners include but are not limited to screws, bolts, pins, etc. The first support portion 112b and the second support portion 112c can also be detachably connected by snapping. The embodiment of the present application does not specifically limit the connection method of the first support portion 112b and the second support portion 112c.

[0099] like Figure 3 and Figure 15As shown, the pressing plate 12 includes a first surface 123 and a second surface 124 arranged along the height direction Z of the laminator. The first surface 123 is the side of the pressing plate 12 facing the upper press 1, and the second surface 124 is the side of the pressing plate 12 facing the lower press 2. The first surface 123 is used to connect with the first driving module 4, and the second surface 124 is used to abut against the laminated stack 100.

[0100] In some embodiments, as Figure 14 As shown, the pressing plate 12 may further include an extension section 125. The extension section 125 extends along the second surface 124 toward the lower press 2. The extension section 125 can abut against the lower press 2. The extension section 125 and the second surface 124 define a receiving space for accommodating the laminated sheet 100. When the pressing plate 12 moves downward along the height direction Z of the laminator, the second surface 124 presses the laminated sheet 100 downward along the height direction Z of the laminator.

[0101] In this embodiment, the extension section 125 can prevent the pressing plate 12 from continuously moving downward along the height direction Z of the laminator to squeeze and damage the laminated sheet 100 during the lamination process, thereby protecting the laminated sheet 100.

[0102] For example, Figure 16 As shown, the specific structure of the extension section 125 can be arranged at multiple intervals along the periphery of the second surface 124, which can reduce the manufacturing cost of the extension section 125 while protecting the laminated sheet 100.

[0103] For example, Figure 17 As shown, the specific structure of the extension section 125 can also be a continuous annular structure along the outer periphery of the second surface 124. This design increases the connection area between the extension section 125 and the second surface 124, improves the strength of the pressure plate 12, and increases the service life of the pressure plate 12.

[0104] Continue to refer Figure 15 As shown, the laminator may also be provided with a sensor 8 , at least part of the structure of the sensor 8 being located between the second surface 124 and the laminated stack 100 .

[0105] Specifically, sensor 8 includes at least one of a pressure sensor and a temperature sensor. That is, the laminator can be equipped with a pressure sensor, a temperature sensor, or both. The pressure sensor and / or temperature sensor can also be connected to the control system via a wired or wireless connection, thereby enabling the control system to control data from the laminator.

[0106] In this embodiment, the pressure sensor 8 or the temperature sensor 8 is used to detect the pressure index or temperature index in the accommodation space during the lamination and fixing process of the laminated stack 100 by the pressing plate 12, thereby reducing the risk of pressure overload or temperature overheating in the accommodation space damaging the laminator, thereby increasing the service life of the laminator.

[0107] In some embodiments, as Figure 3 and Figure 14 As shown, a buffer member 126 is connected to the side of the press plate 12 facing the lower press 2. The buffer member 126 is made of an elastic material. The buffer member 126 is specifically disposed on the second surface 124. When the press plate 12 moves downward along the height direction Z of the laminator, the buffer member 126 can be located between the second surface 124 and the laminated sheet 100 and undergo elastic deformation. The buffer member 126 can be detachably connected to the second surface 124 by bonding or other means.

[0108] In this embodiment, the buffer member 126 can isolate the pressing plate 12 from the laminated laminate 100 during the process of laminating and securing the laminated laminate 100 by the pressing plate 12, thereby providing a certain buffering effect, protecting the pressing plate 12 and the laminated laminate 100, and reducing the risk of damage from impact between the pressing plate 12 and the laminated laminate 100. The buffer member 126 is detachably connected to the pressing plate 12, allowing the user to repair or replace the buffer member 126 according to its usage, thereby extending the service life of the laminator and improving the user experience.

[0109] The hardness of the buffer component 126 ranges from 30HA to 90HA. For example, the hardness of the buffer component 126 can be 30HA, 40HA, 50HA, 60HA, 70HA, 80HA, 90HA, etc.

[0110] When the hardness of the buffer 126 is relatively low, the buffer 126 is too soft and easily elastically deformed. Frequent deformation increases the risk of damage to the buffer 126 , thereby reducing the isolation and protective effect of the buffer 126 on the pressure plate 12 and the laminated stack 100 .

[0111] When the hardness of the buffer 126 is relatively high, the buffer 126 is too hard to be elastically deformed, and cannot alleviate the rigid impact force between the pressing plate 12 and the laminated stack 100 , thereby reducing the isolation and protection effect of the buffer 126 on the pressing plate 12 and the laminated stack 100 .

[0112] When the hardness of the buffer member 126 is in the range of 30HA to 90HA, the hardness of the buffer member 126 is moderate, and the buffer member 126 can both produce elastic deformation and have a certain fatigue resistance, thereby improving the isolation and protection between the pressure plate 12 and the laminated stack 100 and extending the service life of the buffer member 126.

[0113] Exemplarily, the hardness range of the buffer 126 is 30HA~60HA, and the hardness of the buffer 126 can be 30HA, 32HA, 35HA, 38HA, 42HA, 45HA, 48HA, 52HA, 55HA, 58HA, 60HA, etc.

[0114] Exemplarily, the hardness range of the buffer component 126 is 69HA~90HA, and the hardness of the buffer component 126 can be 69HA, 72HA, 75HA, 78HA, 82HA, 85HA, 88HA, 90HA, etc.

[0115] The material type of the buffer 126 can be pure rubber material, pure silicone material, silicone rubber material, silicone and metal composite material, fiber silicone felt material, silicone and polyurethane composite material, etc. The present application does not limit the specific material of the buffer 126.

[0116] Preferably, the buffer member 126 is wool felt or rubber.

[0117] In some embodiments, as Figure 3 As shown, the laminator includes a second sealing member 5, which is installed on the upper press 1 or the lower press 2. When the upper press 1 is pressed downward, the two ends of the second sealing member 5 can contact the upper press 1 and the lower press 2 respectively, so that the upper press 1, the second sealing member 5 and the lower press 2 form a second sealing cavity 20 for accommodating the laminated stack 100, and the pressing plate 12 and the laminated stack 100 are laminated and fixed in the second sealing cavity 20.

[0118] When the second seal 5 is installed on the upper press 1, the second seal 5 can move along the height direction Z of the laminator with the upper press 1; when the second seal 5 is installed on the lower press 2, the second seal 5 does not move along the height direction Z of the laminator with the upper press 1.

[0119] The laminator further comprises a second control member 6 for adjusting the pressure of the second sealed chamber 20 so as to move the pressing plate 12 in a height direction Z of the laminator in a direction away from the lower press 2 .

[0120] The second control component 6 is connected to the second sealed cavity 20, and the second control component 6 is used to adjust the pressure in the second sealed cavity 20 so that the pressing plate 12 moves along the height direction Z of the laminator toward the direction close to the lower press 2. The pressing plate 12 can abut against the laminated stack 100 so that the laminated stack 100 is laminated and fixed.

[0121] Specifically, the second control component 6 in this embodiment can be a vacuum pump. The second sealed cavity 20 is connected to the vacuum pump, and the vacuum pump can pump air into the second sealed cavity 20 to reduce the amount of gas in the second sealed cavity 20 and reduce the pressure, thereby increasing the pressure difference on both sides of the pressure plate 12 in the height direction Z. Under the action of the pressure difference, the pressure plate 12 moves downward along the height direction Z until the pressure plate 12 abuts against the laminated stack 100. Thereafter, the pressure plate 12 continues to apply pressure to the laminated stack 100 under the action of the pressure difference, thereby achieving the lamination and fixation of the laminated stack 100 by the pressure plate 12. In some embodiments, as Figure 3 As shown, the laminator further includes a second driving module 7 , which is connected to the upper press 1 , and the second driving module 7 can drive the upper press 1 to move along the height direction Z of the laminator.

[0122] Specifically, the second driving module 7 can be one of a pneumatic cylinder, a hydraulic cylinder or a motor 47. The specific structures of the pneumatic cylinder, the hydraulic cylinder and the motor 47 can be referred to Figures 6 to 8 As shown, no repeated description is given here.

[0123] The user can drive the upper press 1 through the second driving module 7 to adjust the size of the second sealed cavity 20 along the height direction Z of the laminator to accommodate laminated sheets 100 of different sizes.

[0124] refer to Figure 3 The working process of the laminating machine provided by the present application is as follows: Drive the second driving module 7 to move upward along the height direction Z of the laminator to adjust the second sealed cavity 20 to a suitable size; Placing the laminated sheet 100 on the lower press 2; Drive the second driving module 7 to move downward along the height direction Z of the laminator until one end of the second sealing member 5 abuts against the upper press 1 and the other end abuts against the lower press 2, and the second sealing cavity 20 reaches a closed state; Open the first control member 3 to inflate the first sealed cavity 10, and open the second control member 6 to extract or automatically exhaust air from the second sealed cavity 20. The pressure in the first sealed cavity 10 increases, while the pressure in the second sealed cavity 20 decreases. Driven by the pressure difference between the first sealed chamber 10 and the second sealed chamber 20, the pressing plate 12 moves downward along the height direction Z of the laminator, driving the first sealing member 13 to elastically deform. At this time, when the first driving module 4 is the elastic member 42, the elastic member 42 is compressed; The pressing plate 12 moves downward along the height direction Z of the laminator, the buffer member 126 abuts against the laminated stack 100, and the pressing plate 12 achieves lamination and fixation of the laminated stack 100; The pressure sensor 8 and / or the temperature sensor 8 on the second surface 124 of the press plate 12 monitors the lamination environment in real time; After the lamination and fixing are completed, the laminated sheets 100 are formed into a laminated part. The first control member 3 extracts air from the first sealed cavity 10 or automatically exhausts air. The second control member 6 inflates air into the second sealed cavity 20. The pressure in the second sealed cavity 20 increases, while the pressure in the first sealed cavity 10 decreases. The pressure difference between the first sealed cavity 10 and the second sealed cavity 20 decreases. The elastic member 42 rebounds and stretches, driving the pressing plate 12 to move upward along the height direction Z of the laminator. Drive the second driving module 7 to move upward along the height direction Z of the laminator; The laminate is taken out and the laminator operation is finished.
