[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202411600618.1, filed on November 11, 2024, the contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of solar photovoltaic module lamination preparation technology, and in particular to a laminator. Background Technology

[0004] The laminator is a core piece of equipment in the photovoltaic module manufacturing process. Its main function is to press tempered glass sheets, hot melt adhesive, individual solar cells, hot melt adhesive, and backsheets (or tempered glass sheets) stacked sequentially into photovoltaic modules through vacuum hot pressing. Therefore, the lamination method and the vacuum level of the lamination chamber have a significant impact on the quality of lamination. Summary of the Invention

[0005] This disclosure provides a laminator, including a body, a laminating component, and a drive component. The body has an adjustable-pressure lamination chamber and includes a first wall. The laminating component is disposed within the lamination chamber, and is positioned opposite to the first wall along a first direction. A photovoltaic cell module is disposed between the laminating component and the first wall, and the photovoltaic cell module is supported by the first wall. The drive component includes a power unit and a shaft. A first end of the shaft is connected to the laminating component, and a second end of the shaft is connected to the power unit. The power unit drives the shaft to move along the first direction.

[0006] In the technical solution of this disclosure embodiment, the photovoltaic cell module can be disposed in the lamination cavity, and lamination can be completed in the lamination cavity.

[0007] During lamination, the photovoltaic cell module to be laminated is first placed in the lamination chamber and supported on the first wall. Then, the lamination chamber is adjusted to a vacuum or near-vacuum state. The power unit is then activated to drive the shaft to move in the first direction. Since the first end of the shaft is connected to the laminating component, the movement of the shaft in the first direction can drive the laminating component to move in the first direction. Thus, as long as the shaft moves in the first direction toward the first wall, the laminating component can move toward the first wall, thereby compressing the photovoltaic cell module to be laminated. In this way, the photovoltaic cell module is compressed by the first wall and the laminating component, thus achieving lamination.

[0008] Since this application utilizes the cooperation of the shaft and the power unit to drive the laminating component and thus achieve the lamination of the photovoltaic cell module, instead of using the traditional adhesive sheet deformation lamination method, it can avoid the problem of frequent adhesive sheet replacement due to frequent deformation damage, and reduce the high cost caused by adhesive sheet loss.

[0009] In some embodiments of this disclosure, the machine body has a through hole connecting the inside and outside of the lamination cavity, the through hole extending along a first direction, the power unit being disposed outside the lamination cavity, and the shaft passing through the through hole; the laminator further includes: a sealing element disposed at the through hole for sealing the gap between the through hole and the shaft.

The shaft extends into the telescopic pipe through the clearance hole. The first end of the telescopic pipe is sealed and connected to the second connecting portion. The second connecting portion is connected to the machine body. The sealing portion is disposed between the second connecting portion and the machine body and bypasses the hole.

[0012] In some embodiments of this disclosure, the extension direction of the telescopic conduit is consistent with the axial direction of the shaft.

[0013] In some embodiments of this disclosure, the laminator further includes a guide shaft, and the machine body also has a guide hole communicating with the inside and outside of the lamination cavity. The guide hole extends along a first direction and is located within the range of a telescopic pipe along the first direction. The guide shaft passes through the guide hole, and the first end of the guide shaft extends into the telescopic pipe and is connected to the first connecting part.

[0014] In some embodiments of this disclosure, the laminator further includes a first guide sleeve and a first lubricant. The first guide sleeve is fitted onto a guide shaft and connected within a guide hole. The first lubricant is disposed between the first guide sleeve and the guide shaft.

[0015] In some embodiments of this disclosure, the laminator further includes a second guide sleeve and a second lubricant. The second guide sleeve is fitted onto the shaft and connected within a through hole. The second lubricant is disposed between the second guide sleeve and the shaft.

[0016] In some embodiments of this disclosure, there are multiple shafts and through holes, and they correspond one-to-one. The shafts are inserted into the corresponding through holes, and the projections of the multiple through holes on the laminate are evenly distributed on the laminate along the first direction.

[0017] In some embodiments of this disclosure, the laminator further includes a synchronizing element disposed outside the lamination chamber. The synchronizing element is connected to the second end of a plurality of shafts, and a power unit is connected to the synchronizing element to drive the synchronizing element to move along a first direction.

[0018] In some embodiments of this disclosure, the laminator further includes a buffer element laid on the side surface of the first wall facing the laminator, the buffer element being used to support the photovoltaic cell module.

[0019] In some embodiments of this disclosure, the body further includes a cover, which is disposed on one side of the first wall along a first direction. A groove is formed on the surface of the cover facing the first wall. The first wall is fastened to the groove opening and forms a laminated cavity with the groove.

[0038] The following is a detailed description of this disclosure.

[0039] With the development of the photovoltaic industry, the demand for both the quantity and quality of photovoltaic cell modules is increasing. Therefore, the photovoltaic equipment used to produce photovoltaic cell modules also needs to keep pace with the times to meet production needs.

[0040] The laminator is the core equipment in the photovoltaic cell module production process. Its main function is to press the tempered glass plate, hot melt adhesive, single solar cell, hot melt adhesive, and back sheet (or tempered glass plate) stacked in sequence into a photovoltaic cell module through vacuum hot pressing.

[0041] In related technologies, a laminator includes a body and a laminating plate. The laminating plate is located inside the body and forms an independent and sealed first chamber and a second chamber with the body. The air pressure inside the first chamber and the second chamber is adjustable.

[0042] During lamination, the photovoltaic cell module is placed in the first cavity and supported on the machine body, creating a high-temperature environment in both the first and second cavities. Then, the air pressure in the second cavity is changed, causing the adhesive sheet to deform and bulge into the second cavity, thus contacting the photovoltaic cell module. Under the high temperature and pressure of the adhesive sheet, the hot melt adhesive melts and bonds the tempered glass and the individual solar cell adhesive together, thus bonding the individual solar cell to the backsheet (or tempered glass plate). This achieves bonding between the tempered glass plate, the individual solar cell, and the backsheet (or tempered glass plate), ensuring the lamination effect.

[0043] However, there are several problems with using laminates:

[0044] First, the adhesive sheets need to be preheated and baked before lamination, which increases electricity costs.

[0045] Secondly, during the lamination process, the adhesive sheet undergoes frequent and repeated deformations under high temperatures. Therefore, with each deformation, the adhesive sheet is prone to damage, requiring frequent replacement. This not only increases the material cost of the adhesive sheet but also the labor cost of replacement, thus raising the overall lamination cost. Furthermore, if the adhesive sheet is damaged during lamination, it directly affects the quality of the currently laminated photovoltaic module.

[0046] Third: When changing the adhesive sheets, the laminator needs to be shut down, which will also result in a loss of production capacity.

[0047] Fourth: It is quite difficult to render the scrapped rubber sheets harmless.

[0048] To address the aforementioned problems, this disclosure provides a novel lamination method that replaces the traditional method of lamination using adhesive sheets, thereby overcoming these issues. The solution described in this disclosure is illustrated in detail below with reference to Figures 1-5.

[0049] In some embodiments, as shown in Figures 1-2, this disclosure provides a laminator 01, which includes a body 1, a laminating component 2, and a drive component 3. The body 1 has a lamination chamber a with adjustable air pressure and includes a first wall 11. The laminating component 2 is disposed in the lamination chamber a along a first direction X, and is disposed opposite to the first wall 11. A photovoltaic cell module 02 is disposed between the laminating component 2 and the first wall 11, and the photovoltaic cell module 02 is supported by the first wall 11. The drive component 3 includes a power unit 31 and a shaft 32. The first end of the shaft 32 is connected to the laminating component 2, and the second end of the shaft 32 is connected to the power unit 31. The power unit 31 is used to drive the shaft 32 to move along the first direction X.

[0050] As can be understood, as shown in Figures 1-2 and 4-5, the first end of the shaft 32 is the lower end of the shaft 32, and the second end of the shaft 32 is the upper end.

[0051] It is understandable that during lamination, the temperature inside the lamination chamber a needs to be within a suitable range so that the hot melt adhesive is in a molten state, thereby achieving bonding and fixing between the various components of the photovoltaic cell module 02 under the pressure of the laminating component 2.

[0052] In some examples, after the body 1 is placed in a predetermined position, the first direction X can be the height direction of the body 1.

[0053] In some examples, the photovoltaic module 02 can be a single-glass module, comprising a tempered glass panel, individual solar cells, and a backsheet stacked together. Hot melt adhesive is applied between the tempered glass panel and the individual solar cells, and between the backsheet and the individual solar cells. The backsheet provides support for the individual solar cells, and the tempered glass panel provides protection for them.

[0054] In other examples, the photovoltaic module 02 can also be a double-glass module, comprising a tempered glass panel, a single solar cell, and another tempered glass panel stacked together, with hot melt adhesive placed between the tempered glass panel and the single solar cell. The tempered glass panel provides protection for the single solar cell, and since both sides of the double-glass module can absorb light, power generation efficiency and output can be guaranteed.

[0055] For example, the hot melt adhesive may be an ethylene-vinyl acetate copolymer (EVA).

[0056] In some examples, the laminate 2 is a plate-like structure, which is parallel to the first wall 11. The laminate 2 is a structural component that is resistant to high temperature and high pressure and has high hardness.

[0057] For example, after the photovoltaic cell module 02 is placed on the first wall 11, the projection of the laminate 2 on the first wall 11 along the first direction X covers at least one photovoltaic cell module 02.

[0058] The thickness of the laminate 2 ranges from 15mm to 60mm. For example, the thickness range of the laminate 2 can be 15mm-30mm, 30mm-60mm, 25mm-50mm, or 40mm-60mm, etc.

[0059] For example, the thickness of the laminate 2 can be 15mm, 20mm, 30mm, 40mm, 50mm or 60mm, etc.

[0060] In some examples, there can be multiple driving components 3. The first end of the shaft 32 of each driving component 3 is connected to the laminating component 2. The first ends of the multiple shafts 32 are evenly distributed on the laminating component 2 within the extension plane of the laminating component 2. With this configuration, the multiple shafts 32 can move synchronously along the first direction X, thereby synchronously driving the laminating component 2 to approach or move away from the photovoltaic cell module 02, thus achieving the lamination of the photovoltaic cell module 02.

[0061] The extension plane of the laminate 2 is a plane, which is perpendicular to the first direction X.

[0062] In some examples, the driving element 3 can be located inside the lamination cavity a, or the driving element 3 can be located outside the lamination cavity a. For example, the driving element 3 is located on the side of the lamination element 2 away from the first wall 11. With this arrangement, when the lamination element 2 laminates the photovoltaic cell module 02, the driving element 3 can be avoided from affecting the lamination.

[0063] For example, the power unit 31 can be an actively driven component such as a cylinder or a motor. Of course, the power unit 31 can also be an elastic element with adjustable elasticity (such as a spring), and by adjusting the elasticity of the elastic element, the shaft 32 is moved, thereby causing the laminate 2 to move to press the photovoltaic cell module 02.

[0064] In some examples, the laminator 01 also includes a pressure regulating component, which is connected to the lamination chamber a and used to regulate the air pressure within the lamination chamber a. With this configuration, when laminating the photovoltaic cell module 02, the pressure regulating component first extracts gas from the lamination chamber a, bringing it to a vacuum or near-vacuum state. Then, the drive component 3 moves the lamination component 2 to achieve the lamination of the photovoltaic cell module 02. The vacuum or near-vacuum lamination environment facilitates the removal of air bubbles between the tempered glass plate and the individual solar cells, thereby improving the quality of the lamination.

[0065] With the above settings, the photovoltaic cell module 02 can be placed in the lamination chamber a and lamination can be completed in the lamination chamber a.

[0066] During lamination, the photovoltaic cell module 02 to be laminated is first placed in the lamination chamber a and supported on the first wall 11. Then, the lamination chamber a is adjusted to a vacuum or near-vacuum state. Then, the power unit is activated to drive the shaft 32 to move along the first direction X. Since the first end of the shaft 32 is connected to the laminating component 2, the movement of the shaft 32 along the first direction X can drive the laminating component 2 to move along the first direction X. Thus, as long as the shaft 32 moves along the first direction X towards the first wall 11, the laminating component 2 can move towards the first wall 11, thereby squeezing the photovoltaic cell module 02 to be laminated. In this way, the photovoltaic cell module 02 will be squeezed by the first wall 11 and the laminating component 2, thereby achieving lamination.

[0067] Since this application utilizes the cooperation between the shaft 32 and the power unit 31 to drive the laminate 2 and thus achieve the lamination of the photovoltaic cell module 02, and does not adopt the traditional adhesive sheet deformation lamination method, it does not involve the related issues of the adhesive sheet.

[0068] Specifically, there is no heating of the adhesive sheet before lamination, thus saving on electricity costs. During lamination, there is no issue of frequent adhesive sheet deformation and damage requiring frequent replacement, thereby reducing material and replacement costs due to adhesive sheet wear and tear. Since there is no need to replace the adhesive sheet, the laminator 01 can operate continuously for extended periods, increasing production capacity. Furthermore, there is no issue of discarded adhesive sheets or their disposal.

[0069] In some embodiments, the laminate 2 is a plate-like structure, the thickness direction of the plate-like structure is the first direction X, and the material of the laminate 2 includes steel.

[0070] In some examples, along the first direction X, the plate-like structure coincides with the photovoltaic cell module 02, that is, the shape and size of the plate-like structure are completely consistent with the photovoltaic cell module 02.

[0071] In some examples, the material of the laminate 2 includes at least one of carbon steel, alloy steel, or special steel.

[0072] By configuring the laminate 2 as a plate structure as described above, it is easier to process the laminate 2 and also easier to bond and contact the laminate 2 with the photovoltaic cell module 02, thus facilitating lamination. Furthermore, since the laminate 2 is made of steel, it not only has high hardness but also can withstand high temperatures, making it suitable for the application scenarios disclosed herein and ensuring its service life.

[0073] In some embodiments, there are multiple photovoltaic cell modules 02. In a plane perpendicular to the first direction X, the plate structure includes multiple interlocking sub-plates. Each sub-plate corresponds to one of the multiple photovoltaic cell modules 02. Along the first direction X, the projection of the sub-plate onto the first wall 11 is used to cover the corresponding photovoltaic cell module 02.

[0074] In order to drive multiple sub-boards, multiple driving components 3 can be set up, with each driving component 3 corresponding to one of the multiple sub-boards. The first end of the shaft 32 of the driving component 3 is connected to the corresponding sub-board, and the multiple driving components 3 move synchronously to drive the multiple sub-boards to laminate the corresponding photovoltaic cell module 02.

[0075] With the above setup, multiple sub-boards can be used to laminate multiple corresponding photovoltaic cell modules 02, thus ensuring the independence of the lamination of each photovoltaic cell module 02 and guaranteeing their respective lamination effects.

[0076] In other embodiments, along the first direction X, the projection of the plate-like structure onto the first wall 11 is used to cover at least one photovoltaic cell module 02.

[0077] In other words, at least one photovoltaic cell module 02 is laminated on a single sheet of material. For example, two, five, six, nine, or ten photovoltaic cell modules 02 can be laminated on a single sheet of material.

[0078] With the above setup, at least one photovoltaic cell module 02 can be laminated in one go using a plate-like structure. This ensures lamination efficiency and also reduces the installation difficulty of the drive component 3 and the laminating component 2.

[0079] In some embodiments, as shown in FIG3, the laminator 01 further includes a buffer 4, which is laid on the surface of the first wall 11 facing the laminator 2, and the buffer 4 is used to support the photovoltaic cell module 02.

[0080] The buffer 4 can include high-temperature cloth or felt, and the buffer 4 only needs to have a buffering effect and be resistant to high temperature.

[0081] By laying a buffer 4 on the first wall 11, the buffer 4 can provide cushioning for the photovoltaic cell module 02 when the laminate 2 comes into contact with the photovoltaic cell module 02, thereby reducing the probability of damage to the photovoltaic cell module 02.

[0082] In some embodiments, as shown in Figures 1-2, the body 1 further includes a cover 12. Along the first direction X, the cover 12 is disposed on one side of the first wall 11. A groove is formed on the surface of the cover 12 facing the first wall 11. The first wall 11 is fastened to the groove opening and forms a laminated cavity a with the groove. A drive member 3 is disposed on the cover 12.

[0083] In some examples, as shown in Figures 1-2, the cover 12 includes a detachably connected second wall 121 and an isolation portion 122. The second wall 121 is opposite to and spaced apart from the first wall 11. The isolation portion 122 is disposed between the second wall 121 and the first wall 11 and is arranged around the laminate 2 to form a groove with the second wall 121. This arrangement allows the isolation portion 122 and the second wall 121 to be machined separately, and then the isolation portion 122 and the second wall 121 to be connected together to form the cover 12, which facilitates the manufacturing of the cover 12.

[0084] The laminator 01 also includes sealing rings. A sealing ring is disposed between the isolation section 122 and the second wall 121, and a sealing ring is disposed between the isolation section 122 and the first wall 11. The sealing rings are arranged circumferentially around the tank. By providing the sealing rings, the gaps between the first wall 11 and the isolation section 122, and the gaps between the second wall 121 and the isolation section 122, can be sealed, thereby ensuring the airtightness of the lamination chamber a and thus ensuring the quality of lamination.

[0085] For example, a sealing groove can be formed on the isolation part 122, and the sealing groove is arranged around the circumference of the groove body. The sealing ring is disposed in the sealing groove, which can facilitate the setting of the sealing ring and ensure the stability of the seal.

[0086] For example, the cover 12 also includes a connecting plate 123, which is arranged circumferentially around the isolation portion 122 and detachably connected to the isolation portion 122. The connecting plate 123 is also arranged circumferentially around the second wall 121 and detachably connected to the second wall 121. With this arrangement, the isolation portion 122 and the second wall 121 can be detachably connected via the connecting plate 123, thus facilitating the installation and removal of the isolation portion 122 and the second wall 121.

[0087] For example, the connecting plate 123 and the isolation part 122 can be detachably connected to the connecting plate 123 by fasteners. The fasteners can be screws or bolts, etc.

[0088] In some examples, the cover 12 is detachably connected to the first wall 11. With this configuration, when laminating the photovoltaic module 02, the cover 12 and the first wall 11 are separated, the photovoltaic module 02 is placed on the first wall 11, and then the cover 12 is placed on top of the first wall 11 to form a lamination cavity a, thereby achieving lamination. After lamination is complete, the cover 12 is separated from the first wall 11, and the laminated photovoltaic module 02 is then removed. The detachable connection between the cover 12 and the first wall 11 facilitates the placement and removal of the photovoltaic module 02.

[0089] By setting the body 1 into two parts, the first wall 11 and the cover 12, it is easier to process the body 1 and to form the lamination cavity a.

[0090] Based on this, in some embodiments, the laminator 01 further includes a lifting mechanism. The output end of the lifting mechanism is connected to the cover 12. The lifting mechanism can be connected to the first wall 11 or the bottom surface. The lifting mechanism is used to drive the cover 12 to approach or move away from the first wall 11 along the first direction X. By setting the lifting mechanism, it is easier to separate and fasten the cover 12 from the first wall 11, thereby facilitating the placement and removal of the photovoltaic cell module 02.

[0091] The lifting mechanism can be a push rod motor or a telescopic cylinder, etc.

[0092] In some embodiments, as shown in Figures 1-2, the laminator 01 further includes a heating element 10, at least one of the cover 12 and the first wall 11 is made of a thermally conductive material, and the heating element 10 is provided on at least one of the cover 12 and the first wall 11. The heating element 10 is located outside or inside the lamination cavity a.

[0093] The processing methods of the heating element 10 include, but are not limited to, electromagnetic heating, electric heating, oil heating, or lamp heating.

[0094] In addition, the guiding material can be metal, such as aluminum, copper, or composite metal materials.

[0095] In some examples, a heating element 10 is provided outside the lamination cavity a. The heating element 10 is located on the side of the first wall 11 facing away from the lamination element 2. The first wall 11 is made of a thermally conductive material. In this way, the heating element 10 can heat the first wall 11, and the first wall 11 in turn heats the photovoltaic cell module 02, thereby heating both the lamination cavity a and the photovoltaic cell module 02. This arrangement can avoid the heating only affecting the lamination of the photovoltaic cell module 02.

[0096] In some examples, a heating element 10 is provided outside the lamination cavity a. The heating element 10 is located on the cover 12, which is made of a thermally conductive material. In this way, the heating element 10 can heat the cover 12, and the temperature on the cover 12 is transferred to the air inside the lamination cavity a, thereby heating the photovoltaic cell module 02.

[0097] In some examples, a heating element 10 is provided in the lamination cavity a. The heating element 10 is located on the cover 12 and between the lamination 2 and the cover 12. The heating element 10 can bake and heat the lamination 2. After the lamination 2 comes into contact with the photovoltaic cell module 02, the heat can be transferred to the photovoltaic cell module 02, thereby heating the photovoltaic cell module 02.

[0098] By setting up the heating element 10, the heating element 10 can be activated during lamination to heat the lamination chamber a, thereby heating the hot melt adhesive in the photovoltaic cell module 02 and making the hot melt adhesive molten, thus meeting the lamination requirements.

[0099] The position of the drive component 3 on the body 1 is varied. For example, it can be located inside the lamination cavity a, or it can be partially located outside the lamination cavity a. The following is a detailed description.

[0100] In some embodiments, as shown in Figures 1-2 and 3-4, the machine body 1 has a through hole b communicating with the inside and outside of the lamination chamber a. The through hole b extends along a first direction X. The power unit 31 is located outside the lamination chamber a, and the shaft 32 passes through the through hole b. The laminator 01 also includes a sealing element 5, which is located at the through hole b and is used to seal the gap between the through hole b and the shaft 32.

[0101] It is understandable that the seal 5 is located at the through hole b, meaning that the seal 5 can be located inside the through hole b, or along the first direction X, the seal 5 can also be located on at least one side of the through hole b. The purpose of the seal 5 is to prevent the interior and exterior of the lamination cavity a from communicating through the gap between the inner wall of the through hole b and the outer wall of the shaft 32 during lamination, thereby ensuring that the lamination cavity a is in a closed environment during lamination, so as to facilitate the evacuation of the lamination cavity a.

[0102] In some examples, the body 1 includes a cover 12 and a first wall 11. The cover 12 includes a second wall 121 and an isolation part 122. A through hole b is provided on the second wall 121. Since the second wall 121 is opposite to the first wall 11, the through hole b is provided on the second wall 121 so that the drive member 3 is provided on the second wall 121 so that the shaft 32 of the drive member 3 can drive the laminating member 2 to move, so as to use the laminating member 2 to laminate the photovoltaic cell module 02. This avoids the shaft 32 affecting the placement of the photovoltaic cell module 02.

[0103] When sealing the gap between the through hole b and the shaft 32 using the sealing element 5, a static seal can be used. For example, a sealing ring can be directly installed, fixed inside the through hole b, and fitted onto the shaft 32 to achieve a seal. Alternatively, the sealing element 5 can also be a dynamic seal. The sealing element 5 can move with the shaft 32 relative to the through hole b in the first direction X. This type of sealing element 5 has a longer service life and is more suitable for the application scenarios of this disclosure, which will be described in detail below.

[0104] In some embodiments, as shown in Figures 1-2 and 3-4, at least one side of the through hole b has a seal 5 along the first direction X. The seal 5 includes a first connecting portion 51 and a telescopic conduit 52. Along the first direction X, the telescopic conduit 52 is disposed between the first connecting portion 51 and the through hole b, and the through hole b is located within the telescopic conduit 52. The shaft 32 extends into the telescopic conduit 52 through the through hole b. The first end of the telescopic conduit 52 is sealed to the body 1, and the second end of the telescopic conduit 52 is sealed to the first connecting portion 51. When the seal 5 is located inside the lamination chamber a, the first end of the shaft 32 extends into the telescopic conduit 52 and is connected to the first connecting portion 51; when the seal 5 is located outside the lamination chamber a, the second end of the shaft 32 extends into the telescopic conduit 52 and is connected to the first connecting portion 51. The telescopic conduit 52 can extend and retract with the movement of the first connecting portion 51.

[0105] It is understood that, along the first direction X, at least one side of the via b has a seal 5, that is, one via b corresponds to at least one seal 5, and the via b is sealed by at least one seal 5. In addition, when the seal 5 is located inside the lamination cavity a, the seal 5 needs to avoid interfering with the photovoltaic cell module 02 by moving the seal 5.

[0106] Wherein, along the first direction X, the via b is located within the telescopic pipe 52, which means that along the first direction X, the projection of the port of the first end of the telescopic pipe 52 on the body 1 surrounds the via b, thereby covering the via b within the port of the first end of the telescopic pipe 52.

[0107] In some examples, when the body 1 includes a first wall 11, a second wall 121 and an isolation section 122, the through hole b is provided in the second wall 121, so that the first end of the telescopic pipe 52 is sealed to the second wall 121.

[0108] In some examples, the first connection 51 includes a first flange with a first shaft hole, such that the second end of the shaft 32 can pass through the telescopic pipe 52 and extend into the first shaft hole, connecting to the first flange. When sealing the second end of the telescopic pipe 52 using the first flange, bolts or clamps can be used to connect the first flange and the telescopic pipe 52. A sealing ring can also be provided at the connection to ensure a tight seal between the first flange and the first end of the telescopic pipe 52.

[0109] In some examples, the telescopic conduit 52 may include a metal bellows that can extend and retract along its axial direction, thus making it suitable for the application scenarios of this application. Of course, the telescopic conduit 52 may also be other pipes that are capable of extension and retraction and have good sealing performance.

[0110] In some examples, when the seal 5 is located outside the lamination chamber a, that is, when the second end of the shaft 32 is connected to the first connecting part 51, in order to connect the power unit 31 to the second end of the shaft 32, the power unit 31 can be fixed to the body 1, and then the power unit 31 can be connected to the first connecting part 51. Thus, the power unit 31 drives the first connecting part 51 to move along the first direction X, thereby driving the shaft 32 to move along the first direction X, so as to drive the shaft 32.

[0111] In some examples, when the seal 5 is located in the lamination cavity a, that is, when the first end of the shaft 32 is connected to the first connecting part 51, in order to connect the first end of the telescopic shaft to the lamination 2, the lamination 2 can be connected to the first connecting part 51. In this way, when the shaft 32 moves along the first direction X, the shaft 32 can drive the first connecting part 51 to move, and then drive the lamination 2 to move, thereby achieving lamination.

[0112] For example, the first connection 51 includes a first flange, which can be bolted to the laminate 2.

[0113] With the above configuration, since the first end of the telescopic pipe 52 is sealed to the body 1 and the second end of the telescopic pipe 52 is sealed to the first connecting part 51, a sealed telescopic cavity is formed inside the telescopic pipe 52. Since the through hole b is located within the range of the telescopic pipe 52 along the first direction X, when the sealing element 5 is placed outside the lamination cavity a, the gap between the through hole b and the shaft 32 will communicate with the inside of the telescopic cavity. Since the gap between the through hole b and the shaft 32 also communicates with the inside of the lamination cavity a, the inside of the lamination cavity a is connected to the sealed telescopic cavity. Thus, the telescopic cavity can prevent the inside of the lamination cavity a from communicating with the outside of the lamination cavity a through the gap. Furthermore, since the first connecting part 51 and the shaft 32 will move synchronously during the movement of the shaft 32, and the telescopic pipe 52 will expand and contract to adapt to the movement of the first connecting part 51, this not only ensures the movement of the shaft 32 and the normal lamination process, but also ensures the sealing capability of the telescopic pipe 52.

[0114] Similarly, when the sealing element 5 is placed outside the lamination cavity a, the gap between the through hole b and the shaft 32 will communicate with the outside of the expansion cavity. Since the gap between the through hole b and the shaft 32 is connected to the sealed expansion cavity inside the lamination cavity a, but not to the inside of the lamination cavity a, the expansion cavity can prevent the inside of the lamination cavity a from communicating with the outside of the lamination cavity a through the gap. Furthermore, during the movement of the shaft 32, the first connecting part 51 and the shaft 32 will move synchronously, and the expansion pipe 52 will expand and contract to adapt to the movement of the first connecting part 51. In this way, not only is the movement of the shaft 32 guaranteed and the normal lamination process guaranteed, but also the sealing capability of the expansion pipe 52 is guaranteed.

[0115] Based on this, in some embodiments, as shown in Figures 1-2 and 3-4, the sealing element 5 further includes a second connecting portion 53 and a sealing portion 54. The second connecting portion 53 is disposed between the first end of the telescopic pipe 52 and the body 1. The second connecting portion 53 has a clearance hole corresponding to the through hole b. The shaft 32 extends into the telescopic pipe 52 through the clearance hole. The first end of the telescopic pipe 52 is sealed and connected to the second connecting portion 53, and the second connecting portion 53 is connected to the body 1. The sealing portion 54 is disposed between the second connecting portion 53 and the body 1, and is disposed around the hole b.

[0116] It is understood that the second connecting part 53 having a clearance hole corresponding to the through hole b means that the clearance hole extends along the first direction X, and in the first direction X, the clearance hole and the through hole b at least partially overlap, so that the shaft 32 can be inserted into both the clearance hole and the through hole b at the same time without affecting the movement of the shaft 32 along the first direction X.

[0117] In some examples, the second connecting portion 53 includes a second flange with a through second shaft hole, so that the first end of the shaft 32 can pass through the second connecting portion 53 through the second shaft hole, and then extend into the expansion joint 52 to connect with the first connecting portion 51. When using the second flange to seal the first end of the expansion joint 52, bolts or clamps can be used to connect the second flange and the expansion joint 52, and a sealing ring can also be provided at the connection to ensure a tight seal between the second flange and the second end of the expansion joint 52.

[0118] For example, the body 1 includes a first wall 11, a second wall 121 and an isolation part 122. The through hole b is opened in the second wall 121. The second connecting part 53 can be a second flange parallel to the bottom wall, so that the second flange fits tightly with the second wall 121. A sealing part 54 is provided between the second flange and the second connecting part 53 to achieve sealing.

[0119] For example, the second flange can be connected to the second wall 121 by bolts, thus ensuring the stability of the connection.

[0120] In some examples, the sealing part 54 can be an O-ring, which surrounds the outside of the through hole b to ensure a seal between the second connection part 53 and the body 1.

[0121] In some examples, a sealing groove is provided on the side of the second connection 53 facing the body 1. The sealing groove surrounds the outside of the through hole b, and the sealing part 54 is placed in the sealing groove to achieve sealing. By setting the sealing groove, the sealing part 54 can be easily set, and unnecessary movement of the sealing part 54 can be avoided, thereby ensuring the sealing stability of the sealing part 54.

[0122] By providing a second connecting part 53 and a sealing part 54, the second connecting part 53 seals the second end of the telescopic pipe 52, and the second connecting part 53 and the sealing part 54 seal the connection between the telescopic pipe 52 and the body 1. This facilitates the sealed connection between the second end of the telescopic pipe 52 and the body 1, ensuring not only sealing performance but also connection stability.

[0123] In some embodiments, the extension direction of the telescopic pipe 52 is consistent with the axial direction of the shaft 32.

[0124] In other words, the telescopic pipe 52 extends along the first direction X, and the extension direction of the telescopic pipe 52 is consistent with the extension direction of the shaft 32.

[0125] With this configuration, during the movement of the shaft 32 along the first direction X, the telescopic pipe 52 can be extended and retracted along the first direction X, thereby ensuring the consistency between the extension and retraction of the telescopic pipe 52 and the movement of the shaft 32. This not only extends the service life of the telescopic pipe 52, but also ensures the lamination stability and reliability of the laminator 01.

[0126] In some embodiments, as shown in Figures 3-4, the laminator 01 further includes a guide shaft 6, and the machine body 1 also has a guide hole d that connects the inside and outside of the lamination cavity a. The guide hole d extends along the first direction X. Along the first direction X, the guide hole d is located within the telescopic pipe 52. The guide shaft 6 passes through the guide hole d, and the first end of the guide shaft 6 extends into the telescopic pipe 52 and is connected to the first connecting part 51.

[0127] In some examples, the body 1 includes a first wall 11, a second wall 121, and an isolation section 122. Both the guide hole d and the through hole b are located on the second wall 121, and along the first direction X, both the guide hole d and the through hole b are located within the telescopic pipe 52. That is, along the first direction X, the projection of the port of the first end of the telescopic pipe 52 onto the body 1 surrounds both the guide hole d and the through hole b, thereby covering the through hole b and the guide hole d within the port of the first end of the telescopic pipe 52. In this way, the sealing element 5 can simultaneously ensure the sealing at both the through hole b and the guide hole d, thus ensuring the sealing of the lamination cavity a.

[0128] In some examples, there can be multiple guide holes d and guide shafts 6. Multiple guide shafts 6 are arranged in parallel, and multiple guide shafts 6 guide the shaft 32 at the same time, thereby ensuring the smoothness of the shaft 32 moving along the first direction X, and thus ensuring the smoothness of the movement of the laminating component 2 driven by the shaft 32, so as to ensure the stability and effect of the laminating component 2 on the photovoltaic cell module 02, and ensure the quality of the laminated photovoltaic cell module 02.

[0129] In some examples, there are multiple via holes b and multiple shafts 32. Therefore, there are also multiple guide shafts 6 and multiple guide holes d. The multiple guide shafts 6 and multiple guide holes d are divided into multiple groups. The multiple groups of guide holes d and guide holes d correspond to multiple shafts 32. That is, each shaft 32 will be guided by at least one corresponding guide shaft 6 during its movement along the first direction X.

[0130] For example, one shaft 32 corresponds to two guide shafts 6, which are located on both sides of the axis of the shaft 32. This not only ensures the smoothness of the movement of the shaft 32 to a high extent, but also controls the number of guide shafts 6 as much as possible, thus controlling the cost of the parts.

[0131] With the above settings, during the lamination process, as the shaft 32 and the first connecting part 51 move, since the first connecting part 51 is connected to the guide shaft 6, the guide shaft 6 will also move with the first connecting part 51. During the movement, the guide shaft 6 will guide the movement, thereby preventing the shaft 32 from deviating, thus ensuring the smoothness of the movement of the laminating component 2 driven by the shaft 32, ensuring the stability of the lamination and the quality of the photovoltaic cell module 02 after lamination.

[0132] In some embodiments, as shown in Figures 3-4, the laminator 01 further includes a first guide sleeve 7 and a first lubricant. The first guide sleeve 7 is sleeved on the guide shaft 6 and connected within the guide hole d. The first lubricant is disposed between the first guide sleeve 7 and the guide shaft 6.

[0133] The first guide sleeve 7 can be made of a material with high hardness. The first guide sleeve 7 can be snapped into the guide hole d to ensure the durability of the first guide sleeve 7 and the stability of the connection.

[0134] In addition, the first lubricant can be a solid lubricant, such as graphite particles, molybdenum disulfide or boron carbide, etc. The solid lubricant can be embedded into the inner wall of the first guide sleeve 7 to fix the solid lubricant.

[0135] Alternatively, the first lubricant can also be a semi-solid lubricant, such as a thickener, for example, a mineral oil or synthetic oil.

[0136] Through the above settings, the first guide sleeve 7 can prevent the guide shaft 6 from directly contacting the guide hole d, thereby avoiding contact wear between the guide shaft 6 and the guide hole d. At the same time, it can also provide precise guidance for the guide shaft 6, ensuring the smoothness of the movement of the guide shaft 6. The first lubricant can reduce the friction between the guide shaft 6 and the first guide sleeve 7, thereby ensuring the smoothness and stability of the movement of the guide shaft 6. This ensures the smoothness of the movement of the shaft 32 and the stability of the lamination, thus ensuring the lamination quality of the photovoltaic cell module 02.

[0137] In some embodiments, as shown in Figures 3-4, the laminator 01 further includes a second guide sleeve 8 and a second lubricant. The second guide sleeve 8 is sleeved on the shaft 32 and connected within the through hole b. The second lubricant is disposed between the second guide sleeve 8 and the shaft 32.

[0138] The second guide sleeve 8 can be made of a material with high hardness. The second guide sleeve 8 can be snapped into the guide hole d to ensure the durability of the second guide sleeve 8 and the stability of the connection.

[0139] In addition, the second lubricant can be a solid lubricant, such as graphite particles, molybdenum disulfide or boron carbide, etc. The solid lubricant can be embedded into the inner wall of the second guide sleeve 8 to fix the solid lubricant.

[0140] Alternatively, the second lubricant can also be a semi-solid lubricant, such as a thickener, for example, a mineral oil or synthetic oil.

[0141] Through the above settings, the second guide sleeve 8 can prevent the shaft 32 from directly contacting the through hole b, thereby avoiding contact wear between the shaft 32 and the through hole b. At the same time, it can also provide precise guidance for the shaft 32, ensuring the smooth movement of the shaft 32. The second lubricant can reduce the friction between the shaft 32 and the second guide sleeve 8, thereby ensuring the smoothness and stability of the shaft 32's movement and ensuring the lamination quality of the photovoltaic cell module 02.

[0142] In some embodiments, as shown in Figures 1-2, there are multiple shafts 32 and through holes b, which correspond one-to-one. The shaft 32 passes through the corresponding through hole b. Along the first direction X, the projections of the multiple through holes b on the laminate 2 are evenly distributed on the laminate 2.

[0143] It is understandable that the number of vias b can be determined based on the size of the laminate 2, and the size of the laminate 2 can be driven based on the size of the photovoltaic module 02. Here, the size of the laminate 2 refers to the size of the surface of the laminate 2 perpendicular to the first direction X. The size of the photovoltaic module 02 refers to the size of the surface of the photovoltaic module perpendicular to the first direction X.

[0144] For example, a photovoltaic cell module 02 corresponds to ten through holes b and a shaft 32, which can meet the stress requirements of the laminate 2.

[0145] With the above configuration, the vertical projections of multiple shafts 32 on the laminate 2 are evenly distributed on the laminate 2. In this way, multiple shafts 32 can move synchronously, thereby driving the laminate 2 to move together. The configuration of multiple shafts 32 can ensure the synchronicity of movement of various parts of the laminate 2, ensure the stability of movement of the laminate 2, and ensure the uniformity of force on the laminate 2. Thus, after the laminate 2 comes into contact with the photovoltaic cell module 02, it can ensure the uniformity of force on various parts of the force-bearing surface of the photovoltaic cell module 02, thereby ensuring the lamination effect and the lamination quality of the photovoltaic cell module 02.

[0146] In some embodiments, as shown in Figures 2 and 4, the laminator 01 further includes a synchronizing element 9, which is disposed outside the lamination chamber a. The synchronizing element 9 is connected to the second end of a plurality of shafts 32, and the power unit 31 is connected to the synchronizing element 9 to drive the synchronizing element 9 to move along the first direction X.

[0147] In other words, when multiple shafts 32 are provided, the second ends of multiple shafts 32 can be connected simultaneously by a synchronizing member 9, and then at least one power unit 31 can be used to drive the synchronizing member 9 to move along the first direction X, thereby synchronously driving multiple shafts 32 to move along the first direction X.

[0148] In some examples, when the laminator 01 includes a seal 5 located outside the lamination chamber a and the seal 5 includes a first connecting part 51 and a telescopic tube 52, the synchronizing member 9 can be connected to the first connecting part 51 to achieve connection with the second end of the shaft 32.

[0149] In some examples, the power unit 31 can be a cylinder, which can be disposed between the synchronizing member 9 and the body 1, and the output rod of the cylinder extends and retracts along the first direction X to drive the synchronizing member 9 to move along the first direction X, thereby driving the shaft 32 to move along the first direction X.

[0150] Among them, the synchronizing element 9 can be a plate-shaped structure, and the plate-shaped structure is perpendicular to the axis of the shaft 32.

[0151] With the above configuration, during lamination, the power unit 31 can drive the synchronizing member 9 to move. Since the synchronizing member 9 is connected to the second end of the multiple shafts 32, the synchronizing member 9 can synchronously drive the multiple shafts 32 to move along the second direction. This ensures the synchronicity of the movement of the multiple shafts 32 and guarantees the stability and reliability of the lamination.

[0152] Of course, in some other embodiments, the synchronizing element 9 may not be provided. Instead, multiple power units 31 and multiple shafts 32 may be provided, with each power unit 31 corresponding to one of the shafts 32. The power units 31 drive the corresponding shafts 32 to move along the first direction X. In this case, attention needs to be paid to the synchronicity of the starting and stopping of the multiple power units 31.

[0153] To better understand the solutions in this disclosure, two specific embodiments are described below, with the sealing element 5 located inside the lamination cavity a and outside the lamination cavity a, respectively.

[0154] In the first embodiment, as shown in Figures 1-5, the sealing element 5 is disposed inside the lamination cavity a. During lamination, the lifting mechanism first drives the cover 12 to move upward along the first direction X, thereby separating the cover 12 from the first wall 11. At this time, the sealing element 5, the driving element 3, and the laminating element 2 move synchronously with the cover 12. Then, the photovoltaic cell module 02 to be laminated is placed on the first wall 11. Next, the lifting mechanism drives the cover 12 to move downward along the first direction X, thereby locking the cover 12 with the first wall 11 to form the lamination cavity a. Then, the heating element 10 is activated. The lamination chamber a is evacuated. Once the required air pressure and temperature are reached, the evacuation can be stopped. Then, the power unit 31 is activated to drive the shaft 32 to move downward along the first direction X, thereby driving the first connecting part 51 to move. Since the first connecting part 51 is connected to the laminating component 2, the laminating component 2 will move downward under the push of the first connecting part 51 to contact the photovoltaic cell module 02. The photovoltaic cell module 02 is laminated under the pressure of the first wall 11 and the laminating component 2. The photovoltaic cell module 02 can be laminated in one go or in multiple stages.

[0155] After lamination is completed, lamination chamber a can be released, and the lifting mechanism can be used to move the cover 12 upward, and then the photovoltaic cell module 02 can be transported out, thus completing one lamination cycle.

[0156] In the second embodiment, as shown in Figures 1-5, the sealing element 5 is located outside the lamination cavity a. During lamination, the lifting mechanism first drives the cover 12 to move upward along the first direction X, thereby separating the cover 12 from the first wall 11. At this time, the sealing element 5, the driving element 3, the laminating element 2, and the synchronizing element 9 move synchronously with the cover 12. Then, the photovoltaic cell module 02 to be laminated is placed on the first wall 11. Next, the lifting mechanism drives the cover 12 to move downward along the first direction X, thereby locking the cover 12 with the first wall 11 to form the lamination cavity a. Then, the heating element 10 is activated, and the lamination cavity a is evacuated until the air pressure is reached. After the temperature requirement is met, the vacuuming can be stopped, and then the power unit 31 is started to drive the synchronizing member 9 to move downward, so as to drive the first connecting part 51 to move downward. Since the first connecting part 51 is connected to the second end of the shaft 32 and the first end of the shaft 32 is connected to the laminating member 2, the shaft 32 will move downward under the push of the first connecting part 51, and the laminating member 2 will move downward under the push of the first connecting part 51 to contact the photovoltaic cell module 02. The photovoltaic cell module 02 is laminated under the compression of the first wall 11 and the laminating member 2. During the lamination, the photovoltaic cell module 02 can be pressed in one go, or it can be laminated in multiple times.

[0157] After lamination is completed, lamination chamber a can be released, and the lifting mechanism can be used to move the cover 12 upward, and then the photovoltaic cell module 02 can be transported out, thus completing one lamination cycle.

[0158] The above are merely preferred embodiments of this disclosure and do not limit the patent scope of this disclosure. Any equivalent structural or procedural transformations made using the content of this disclosure and its drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this disclosure.
