Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module production, and in particular to a laminating machine. Background Art

[0002] A multi-layer photovoltaic module laminator is a machine that can arrange multiple laminating units in an upper and lower arrangement. To reduce costs, save space, and simultaneously laminate the photovoltaic modules carried by multiple laminating units, the laminating units are typically brought together to close the lamination cavity formed between the upper and lower adjacent laminating units. The adjacent laminating units then laminate the photovoltaic modules within the lamination cavity. After lamination is complete, the laminating units are moved apart to open the lamination cavity.

[0003] Existing multi-layer photovoltaic module laminating machines typically open and close multiple lamination chambers using a steel chain connecting all lamination units simultaneously. A driver then drives the top or bottom lamination unit, opening and closing all lamination chambers sequentially. This approach results in distinct opening and closing times for each lamination chamber, with significant time differences. Consequently, the heat dissipation conditions for the photovoltaic modules within each lamination chamber vary significantly, leading to varying degrees of thermal deformation and impacting the consistency of module production quality. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a laminating machine to solve the problem of a large difference in opening and closing time of each laminating chamber.

[0005] In a first aspect, the present application provides a laminating machine, comprising: a frame, a driving device, a laminating unit, and a rigid linkage device; a plurality of laminating units are arranged in a thickness direction thereof, and each laminating unit is disposed in the frame;

[0006] The rigid linkage device is connected to each laminating unit through transmission.

[0007] The driving end of the driving device is in driving connection with the rigid linkage device, and the driving device drives the laminating units to move closer to or away from each other synchronously through the rigid linkage device.

[0008] Based on the above-mentioned laminating machine, multiple laminating units can be connected through a rigid linkage device. When the rigid linkage device is driven to move by the driving end of the driving device, the rigid linkage device will transmit force to all the laminating units and drive all the laminating units to move synchronously. Specifically, by utilizing the rigid characteristics of the rigid linkage device itself, when it moves, it will cause its relative position relationship with the frame in the thickness direction of the laminating unit to continue to change, and it will also cause the connection position of the rigid linkage device and each laminating unit to continue to change in the thickness direction of the laminating unit. Since the rigid linkage device is a rigid structure, it should be understood that the laminating unit farthest from the transmission connection position between the rigid linkage device and the frame has the fastest movement speed and the largest movement amplitude, and the closer it is to the rigid linkage device, the faster it moves. The smaller the movement speed of the laminating unit at the transmission connection position of the linkage device and the frame, the smaller the movement amplitude, so that all the laminating units can be synchronously approached or synchronously moved away from each other in the thickness direction; this setting can ensure that the photovoltaic modules on all laminating units in the same laminator are heated for the same time, ensure that the deformation degree of all photovoltaic modules is consistent, reduce the damage rate of the battery cells during the lamination process, and also ensure that the melting degree of the film in all photovoltaic modules is consistent, so that the lamination of photovoltaic modules in each lamination cavity is more uniform, and reduce the difficulty of process adjustment of photovoltaic modules. At the same time, since this method of synchronously opening or closing all lamination cavities does not need to take care of individual photovoltaic modules that have been heated for too long, it can also further improve the production efficiency and applicability of the entire laminator.

[0073] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0074] A multi-layer photovoltaic module laminator is a machine that can arrange multiple laminating units in an upper and lower arrangement. To reduce costs and enable simultaneous lamination of photovoltaic modules carried by multiple laminating units, the laminating units are typically brought together to close the lamination cavity formed between adjacent laminating units. The adjacent laminating units then laminate the photovoltaic modules within the lamination cavity. After lamination is complete, the laminating units are moved apart to open the lamination cavity.

[0075] Existing multi-layer photovoltaic module laminating machines typically open and close multiple lamination chambers using a steel chain connecting all lamination units simultaneously. A driver then drives the top or bottom lamination unit, opening and closing all lamination chambers sequentially. This approach results in distinct opening and closing times for each lamination chamber, with significant time differences. Consequently, the heat dissipation conditions for the photovoltaic modules within each lamination chamber vary significantly, leading to varying degrees of thermal deformation and impacting the consistency of module production quality.

[0076] The laminating unit is a mechanism used to carry, transport, and heat the photovoltaic modules to be laminated. It primarily includes a heating plate, high-temperature cloth, a vacuum pump, a sealing ring, and a laminating component. When two adjacent laminating units approach each other, the sealing ring located below the upper laminating unit seals the cavity between them, forming a laminating chamber. This allows the upper laminating unit to first vacuum the photovoltaic modules within the laminating chamber, then inflate them for lamination. The laminating component then laminates the photovoltaic modules within the laminating chamber.

[0077] Based on this, the present application provides a laminating machine that can connect multiple laminating units through a rigid linkage device. When the rigid linkage device is driven to move by the driving end of the driving device, the rigid linkage device will transmit force to the laminating unit connected to the rigid linkage device, and drive the relevant laminating units to move at the same time. Specifically, by utilizing the rigid characteristics of the rigid linkage device itself, when it moves, it will cause its relative position relationship with the frame in the thickness direction of the laminating unit to continue to change, and it will also cause the connection position of the rigid linkage device and each laminating unit to continue to change in the thickness direction of the laminating unit. Since the rigid linkage device is a rigid structure, it should be understood that the laminating unit farthest from the transmission connection position between the rigid linkage device and the frame has the fastest movement speed and the largest movement amplitude. The larger the laminating unit is, the closer it is to the transmission connection position between the rigid linkage device and the frame, the slower the movement speed and the smaller the movement amplitude, so that all the laminating units can be synchronously approached or moved away from each other in the thickness direction; this arrangement can ensure that the photovoltaic modules on all laminating units in the same laminator are heated for the same time, ensure that the deformation degree of all photovoltaic modules is consistent, reduce the damage rate of the battery cells during the lamination process, and also ensure that the melting degree of the film in all photovoltaic modules is consistent, so that the lamination of photovoltaic modules in each lamination cavity is more uniform, and reduce the difficulty of process adjustment of photovoltaic modules. At the same time, since this method of synchronously opening or closing all lamination cavities does not need to take care of individual photovoltaic modules that have been heated for too long, it can also further improve the production efficiency and applicability of the entire laminator.

[0078] In one implementation, the rigid linkage device 4 described in the present application can be a transmission structure formed by a rod or a bar-like hinge, or it can be a transmission arm 41 formed by a rod, a bar or a similar structure, which is connected to each lamination unit 3 through the transmission arm 41, and the swing of the transmission arm 41 is used to drive each lamination unit 3 to move.

[0079] Alternatively, the rigid linkage device 4 described in the present application may also be a frame with a track, and the laminating unit 3 may be slidably installed on the frame 1 through a sliding device, and a laminating unit 3 is slidably connected to each track. The tracks are arranged in sequence from top to bottom on the frame, and the first ends of the tracks are close to each other, and the second ends of the tracks are away from each other. The laminating unit 3 is driven to slide or roll along the first end of the track to the second end through the movement of the frame, and the laminating unit 3 rises along the thickness direction of the laminating unit 3 under the limiting action of the sliding device to separate adjacent laminating units 3, or the laminating unit 3 is driven to move or roll along the second end of the track to the first end through the movement of the frame to drive adjacent laminating units 3 to approach each other.

[0080] Similarly, the frame with tracks can also be replaced by a plate with a limiting channel. The layout of the limiting channel is consistent with the layout of the track on the frame. The laminating unit 3 is driven to move along the first end to the second end of the limiting channel by the movement of the plate. The laminating unit 3 rises under the limiting action of the slide rail to separate adjacent laminating units 3, or the laminating unit 3 is driven to move along the second end to the first end of the limiting channel by the movement of the plate to drive adjacent laminating units 3 to approach each other.

[0081] Reference Figures 1 to 20 As shown, in one implementation, the present application provides a laminating machine, which includes: a frame 1, a driving device 2, a laminating unit 3 and a rigid linkage device 4; a plurality of laminating units 3 are arranged in the frame 1, and the plurality of laminating units 3 are arranged in the thickness direction thereof, and the thickness direction refers to the direction perpendicular to the plane where the laminating unit 3 is located, which can specifically be the direction of gravity; the rigid linkage device 4 is transmission-connected to each laminating unit 3.

[0082] In one implementation, the rigid linkage device 4 is a swing arm, and the rigid linkage device 4 can be indirectly connected to the frame 1 through one of the lamination units 3, that is, one of the lamination units 3 is fixedly set on the frame 1, the rigid linkage device 4 is connected to the fixed lamination unit 3, and the driving end of the driving device 2 is connected to the rigid linkage device 4. Specifically, the fixed lamination unit 3 is installed at the top of the frame 1, the first end of the rigid linkage device 4 is rotatably connected to the side of the fixed lamination unit 3, and the driving end of the driving device 2 is connected to the middle or second end of the rigid linkage device 4. By driving the rigid linkage device 4 to move, the movement of other lamination units 3 connected to the rigid linkage device 4 is driven.

[0083] In one implementation, the rigid linkage device 4 is a swing arm, the rigid linkage device 4 is directly connected to the frame 1, and the driving end of the driving device 2 is transmission-connected to the rigid linkage device 4. The driving end of the driving device 2 can be directly connected to the rigid linkage device 4 to achieve transmission coordination, or the driving end of the driving device 2 can be connected to any one or more lamination units 3, and the driving device 2 drives the lamination unit 3 connected thereto to move, and the lamination unit 3 then drives the remaining lamination units 3 to move through the rigid linkage device 4, thereby achieving transmission coordination with the rigid linkage device 4, and finally achieving the driving device 2 driving the lamination units 3 to move synchronously closer to or away from each other through the rigid linkage device 4.

[0084] In one implementation, the laminating machine provided in the present application can connect multiple laminating units 3 through a rigid linkage device 4. When the rigid linkage device 4 is driven to move by the driving end of the driving device 2, the rigid linkage device 4 will transfer force to all the laminating units 3 and drive all the laminating units 3 to move synchronously. Specifically, by utilizing the rigid transmission characteristics of the rigid linkage device 4 itself, when it moves, it will cause its relative position relationship in the thickness direction of the laminating unit 3 to continue to change, and will also cause the connection position of the rigid linkage device 4 and each laminating unit 3 to continue to change in the thickness direction of the laminating unit 3. Among them, the rigid linkage device 4 drives the laminating unit 3 to change in the thickness direction, which means that when the rigid linkage device 4 is driven by the rigid linkage device 4, there is a height difference between the initial position and the position after a certain movement of the laminating unit 3, and it does not limit the laminating unit 3 to move only in the thickness direction.

[0085] Since the rigid linkage device 4 is a rigid structure, it should be understood that the laminating unit 3 that is farthest away from the transmission connection position between the rigid linkage device 4 and the frame 1 has the fastest movement speed and the largest movement amplitude, and the laminating unit 3 that is closer to the transmission connection position between the rigid linkage device 4 and the frame 1 has a smaller movement speed and a smaller movement amplitude, so that all laminating units 3 can be synchronously approached or synchronously moved away from each other in the thickness direction; such a setting can ensure that the photovoltaic components 8 on all laminating units 3 in the same laminator are heated for the same time, ensure that the deformation degree of all photovoltaic components 8 tends to be consistent, reduce the damage rate of the battery cells during the lamination process, and also ensure that the melting degree of the film in all photovoltaic components 8 tends to be consistent, so that the lamination of the photovoltaic components 8 in each lamination cavity is more uniform, and reduce the difficulty of process adjustment of the photovoltaic components 8. At the same time, since this method of synchronously opening or closing all lamination cavities does not need to take care of individual photovoltaic components 8 that are heated for too long, it can also further improve the production efficiency and applicability of the entire laminator.

[0086] In some embodiments, the rigid linkage device 4 includes a transmission arm 41, and a movable portion 412 is provided on the transmission arm 41, which is connected to each lamination unit 3 in a one-to-one manner. The driving end of the driving device 2 is transmission-connected to the transmission arm 41. Specifically, the driving end of the driving device 2 can be hinged to the rigid body of the transmission arm 41, or can be hinged to at least one movable portion 412, or can be hinged to at least one lamination unit 3. Driven by the driving device 2, the transmission arm 41 swings in the thickness direction of the lamination unit 3, and then drives the corresponding lamination units 3 to move closer to or away from each other synchronously in the thickness direction through the movable portion 412. It should be understood that the transmission arm 41 can be a straight arm structure, or it can be a straight arm structure. It is a support arm structure with a curved arm or an irregular shape, as long as it can ensure that all the movable parts 412 are arranged at intervals in one direction, and through the rotation of the transmission arm 41, all the movable parts 412 can be synchronously moved closer to or away from each other in the thickness direction of the lamination unit 3; specifically, the rigid linkage device 4 can also be a plate-like structure, and the rigid linkage device 4 can be provided with a sliding groove structure extending along the set direction, and the sliding groove structure is used to slide with the lamination unit 3. By driving the rigid linkage device 4 to rotate itself, the sliding groove structure is driven to rotate, and then the slider structure on the lamination unit 3 that slides with the sliding groove is driven to move along the thickness direction of the lamination unit 3, thereby driving all the lamination units 3 to open and close synchronously.

[0087] In a further embodiment, the transmission arm 41 further includes a rotating portion 411 rotatably connected to the frame 1, the transmission arm 41 is transmission-connected to the driving end of the driving device 2, and the driving end of the driving device 2 is used to drive the transmission arm 41 to swing around the rotating portion 411, and the swing plane of the transmission arm 41 is perpendicular to the plane where the laminating unit 3 is located; that is, the transmission arm 41 is rotationally matched with the frame 1 through the rotating portion 411, and the driving device 2 is used to drive the transmission arm 41 to rotate around the rotating portion 411, and the transmission arm 41 is rotated around the rotating portion 411. The rotating part 411 can specifically include a rotating shaft and a rotating shaft groove, and the extension direction of the rotating shaft and the rotating shaft groove is perpendicular to the side of the laminating unit 3. One of the rotating shaft and the rotating shaft groove is arranged on the transmission arm 41, and the other is arranged on the laminating unit 3, and the two can rotate relative to each other around their axes; further, the two can also be slidably plugged in the direction of their axes, thereby further improving the assembly efficiency of the transmission arm 41 and the laminating unit 3.

[0088] In one implementation, the rotating portion 411 may specifically include a rotating shaft and a rotating shaft groove, the extension direction of the rotating shaft and the rotating shaft groove being perpendicular to the side of the laminating unit 3, one of the rotating shaft and the rotating shaft groove being arranged on the transmission arm 41, the other being arranged on the frame 1, or the other being arranged on the laminating unit 3, and the laminating unit 3 being fixedly mounted on the frame 1.

[0089] In one implementation, two transmission arms 41 can be provided, and the two transmission arms 41 are provided on one side of the laminating unit 3 and along the length direction of the laminating unit 3. Of course, in order to make the operation of the laminating unit 3 smoother, a moving track with the same movement track as the laminating unit 3 can be provided on the other side of the laminating unit 3 to guide the movement of the laminating unit 3. According to needs, the laminating units 3 can be provided in three, four, five, six, seven, eight, nine, ten or more.

[0090] In one implementation, the transmission arm 41 can be arranged on both sides of the lamination unit 3 in the width direction, that is, the transmission arm 41 is arranged on both length directions of the lamination unit 3. In this way, both sides of the lamination unit 3 in the length direction are acted upon by force, thereby ensuring the uniformity of the force on the lamination unit 3 and making the movement of the lamination unit 3 smoother.

[0091] It should be understood that the number of transmission arms 41 can be two groups, and the two groups of transmission arms 41 are symmetrically arranged on both sides of the laminating unit 3 in the width direction. The two groups of transmission arms 41 can improve the stability and reliability of multiple laminating units 3 during opening and closing movements, while also reducing the stress on each transmission arm 41, further improving the stability and reliability of the entire laminating machine; specifically, the number of transmission arms 41 in each group can be no less than two, so that the arrangement can ensure that the laminating unit 3 can also achieve uniform support in the length direction, further ensuring the synchronization of all laminating units 3 during opening and closing movements. The length direction of the laminating unit 3 refers to the material conveying direction in which the laminating unit 3 receives and outputs materials, and the width direction of the laminating unit 3 is horizontally perpendicular to the material conveying direction.

[0092] In some embodiments, the spacing between every two adjacent movable parts 412 is equal. Specifically, the spacing between every two adjacent movable parts 412 in the thickness direction of the laminating unit 3 is equal. Furthermore, the spacing between every two adjacent movable parts 412 in the thickness direction of the laminating unit 3 is equal to the spacing between the rotating part 411 and the movable part 412 adjacent thereto in the thickness direction of the laminating unit 3. Such an arrangement can achieve synchronous movement of all movable parts 412 in the thickness direction of the laminating unit 3 when the transmission arm 41 rotates a certain angle around the rotating part 411, thereby ensuring that all laminating units 3 can be closed at the same time, or at any time. Time, all lamination units 3 can maintain the same spacing, thereby further ensuring that the photovoltaic modules 8 on all lamination units 3 in the same laminator are heated for the same time, ensuring that the deformation degree of all photovoltaic modules 8 tends to be consistent, reducing the damage rate of the battery cells during the lamination process, and at the same time, it can also ensure that the melting degree of the film in all photovoltaic modules 8 tends to be consistent, making the lamination of the photovoltaic modules 8 in each lamination cavity more uniform, reducing the difficulty of process adjustment of the photovoltaic modules 8. At the same time, since this method of synchronously opening or closing all lamination cavities does not need to take care of individual photovoltaic modules 8 that have been heated for too long, it can also further improve the production efficiency and applicability of the entire laminator.

[0093] Continue to refer to Figures 4 to 7 As shown, in some embodiments, the transmission arm 41 forms a rotating portion 411 at the first end along its extension direction, and the transmission arm 41 is provided with a movable portion 412 in its length direction. The laminating unit 3 is connected to the transmission arm 41 through the movable portion 412. The driving end of the driving device 2 is directly or indirectly connected to the second end of the transmission arm 41, and the driving device 2 is used to drive the transmission arm 41 to swing. Since the swing amplitude of the movable portion 412 close to the rotating portion 411 is small when the transmission arm 41 rotates around the rotating portion 411, and the swing amplitude of the movable portion 412 away from the rotating portion 411 is large, at this time, when the movable portion 412 drives the laminating unit 3 connected thereto to rise or fall, it and the rotating portion 412 are in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being The spacing between 11 is proportional to the length of the resistance arm, that is, it is more laborious for the driving device 2 to drive the movable part 412 away from the rotating part 411 to rise or fall to a certain height than to drive the movable part 412 close to the rotating part 411 to rise or fall to a certain height. Therefore, the rotating part 411 is set at the first end of the transmission arm 41, and the driving end is connected to the second end of the transmission arm 41. At this time, the rotating part 411 forms a fulcrum, and the length of the power arm is close to the total length of the transmission arm 41, which can significantly extend the power arm, thereby utilizing the lever principle to achieve effort saving; such a setting is both stable and reliable, and can reduce the number of driving devices 2, reducing the overall cost and control difficulty.

[0094] Reference Figure 4As shown, in one implementation, the first end of the transmission arm 41 is installed on the top of the frame 1; or it is installed on the topmost lamination unit 3 among multiple lamination units 3, and the topmost lamination unit 3 is fixedly installed on the frame 1; the second end of the transmission arm 41 is connected to the driving device 2, or the second end of the transmission arm 41 is connected to the bottommost lamination unit 3, and the driving device 2 drives the bottommost lamination unit 3 to move, and drives the transmission arm 41 to swing through the bottommost lamination unit 3, so that the lamination unit 3 in the middle part of the transmission arm 41 also moves with the transmission arm 41, and finally realizes the lamination units 3 approaching or moving away from each other.

[0095] Of course, in order to achieve better support and more uniform force application for the laminating unit 3, the second end of the transmission arm 41 can be connected to a support plate 9, and the driving end of the driving device 2 is connected to the support plate 9. The support plate 9 drives the transmission arm 41 to swing and then drives the movement of the laminating unit 3 connected to the transmission arm 41. When the laminating machine adopts multiple transmission arms 41 for transmission, the second ends of all transmission arms 41 are connected to the support plate 9, and are driven by the support plate 9 to swing synchronously. When multiple laminating units 3 are close to each other, the support plate 9 can provide uniform support for the laminating units 3. The support plate 9 can be made of steel plate, iron plate or other hard alloy material.

[0096] When the lamination cavity between the lamination units 3 is closed, the support plate 9 and the lamination unit 3 above it are also close to each other, and a lower sealed cavity is formed at the close position. When the lamination cavity is evacuated, the support plate 9 can prevent the atmospheric pressure from directly acting on the lowest lamination unit 3, causing the lamination unit 3 to deform.

[0097] In one implementation, the laminating unit 3 is provided corresponding to the movable part 412 in the middle of the transmission arm 41, and the support plate 9 is provided corresponding to the second end of the transmission arm 41; the movable part 412 can be a roller that can rotate on the transmission arm 41, and the movable part 412 is provided on the guide track below the corresponding laminating unit 3, and the second end of the transmission arm 41 is also provided with a roller, and the support plate 9 is provided with a track for the roller to roll. The driving device 2 is connected to the support plate 9, and the driving device 2 drives the support plate 9 to rise, so that the support plate 9 drives the transmission arm 41 to swing along the support plate 9, and the transmission arm 41 drives the laminating unit 3 in the middle position to rise, and the roller in the middle position rolls along the guide track below the corresponding laminating unit 3 while supporting the corresponding laminating unit 3 to rise.

[0098] Specifically, refer to Figures 4 to 8As shown, the slide rail 6 can be set on the support plate 9, and the second end of the transmission arm 41 can be provided with a sliding portion 413 for rolling cooperation with the slide rail 6. The sliding portion 413 can be a roller that rolls with the slide rail 6, or a slider that slides with the slide rail 6. The sliding portion 413 is set at the lower end of the transmission arm 41 in the thickness direction of the laminating unit 3. When the driving device 2 lifts the support plate 9 upward, the sliding portion 413 rolls or slides on the slide rail 6, and the transmission arm 41 starts to swing and drives the adjacent laminating units 3 to close through all the movable parts 412. When the driving device 2 moves downward, the support plate 9 and all the laminating units 3 fall along the swinging action of the transmission arm 41 under the action of gravity, thereby realizing the opening of the adjacent laminating units 3.

[0099] Continue to refer to Figures 9 to 12 As shown, in some embodiments, a rotating part 411 is provided in the middle of the transmission arm 41, and the other multiple movable parts 412 are symmetrically arranged on the transmission arm 41 on both sides of the rotating part 411, and the driving device 2 is directly or indirectly connected to either end of the transmission arm 41 to drive the transmission arm 41 to swing; at this time, the parts of the transmission arm 41 on both sides of the rotating part 411 can synchronously drive all the laminating units 3 to open and close synchronously, and this arrangement can effectively reduce the situation where one end of the transmission arm 41 is subjected to excessive force, so that the force on the entire transmission arm 41 can be more uniform; it should be noted that the driving device 2 can be connected to either end of the transmission arm 41, so as to amplify the power arm and achieve a labor-saving effect. The driving end of the driving device 2 can also be connected to the rotating part 411 or any position between the rotating part 411 and either end of the transmission arm 41, as long as it can be ensured that the driving device 2 can drive the transmission arm 41 to drive all the laminating units 3 to open and close synchronously.

[0100] Continue to refer to Figures 13 to 18As shown, in other embodiments, the transmission arm 41 includes a first arm 4101 and a second arm 4102, and the driving device 2 includes a first driving device 21 and a second driving device 22; the first end of the first arm 4101 and the first end of the second arm 4102 are both installed in the middle of the frame 1, the first arm 4101 extends along the middle of the frame 1 toward the upper part of the frame 1, and is connected to the laminating unit 3 on the upper side of the middle part of the frame 1 through the movable part 412; the second arm 4102 extends along the middle of the frame 1 toward the lower part of the frame 1, and is connected to the laminating unit 3 on the lower side of the middle part of the frame 1 through the movable part 412; the first driving device 21 is directly or indirectly connected to the second end of the first arm 4101 to drive the first arm 4101 to swing; the second driving device 22 is directly or indirectly connected to the second end of the second arm 4102 to drive the second arm 4102 to swing; it should be understood that the first arm 4101 and the second arm 4102 are both complete transmission arms 41, The first arm 4101 and the second arm 4102 both have all the structures of the transmission arm 41, such as the rotating part 411 and the movable part 412. The first arm 4101 and the second arm 4102 are respectively located on both sides of the middle part of the frame 1 in the thickness direction of the laminating unit 3. The first end of the first arm 4101 and the first end of the second arm 4102 are both installed in the middle part of the frame 1. Specifically, the first end of the first arm 4101 and the first end of the second arm 4102 are both rotated with the middle part of the frame 1 through the rotating part 411; the first arm 4101 and the second arm 4102 are respectively controlled by the first drive device 21 and the second drive device 22, so that all the laminating units 3 located on the same side of the middle part of the frame 1 can be opened and closed synchronously, and the two groups of laminating units 3 located on both sides of the middle part of the frame 1 can also be opened and closed synchronously or asynchronously, so that the control is more flexible, and the upper and lower groups of laminating units 3 share one frame 1, and the overall structure is more compact and simpler.

[0101] By setting the rotation directions of the first arm 4101 and the second arm 4102 in opposite directions, the first arm 4101 and the second arm 4102 can be stretched and opened together to the left or stretched and opened together to the right, avoiding the problem of the top and bottom of the lamination unit 3 opening in different directions and occupying a large space due to the rotation of a single transmission arm 41.

[0102] Continue to refer to Figures 9 to 18As shown, one of the laminating units 3 is a fixed laminating unit, which is fixedly arranged on the frame 1 and connected to the rotating part 411; it should be understood that one of the laminating units 3 can move up and down without following the swing of the transmission arm 41, and it is only necessary to make the other laminating units 3 follow the swing of the transmission arm 41 and synchronously approach the fixed laminating unit or synchronously move away from the fixed laminating unit; such a setting can not only ensure that all the laminating units 3 can complete synchronous opening and closing, but also reduce the burden on the transmission arm 41, and improve efficiency and stability; at the same time, such a setting can use the fixed laminating unit to form a reference plane, and no longer need to refer to the frame 1, so as to accurately adjust the position, angle, etc. of all the laminating units 3 during movement.

[0103] In a further embodiment, there are at least two rigid linkage devices 4, and at least two rigid linkage devices 4 are arranged along the length direction of the laminating unit 3. Such an arrangement can ensure that the laminating unit 3 can form at least two supports in the length direction, further ensuring the synchronization of all laminating units 3 during opening and closing movements; or, there are at least two rigid linkage devices 4, and at least two rigid linkage devices 4 are respectively arranged on both sides of the width direction of the laminating unit 3. Through the at least two rigid linkage devices 4, the stability and reliability of multiple laminating units 3 during opening and closing movements can be improved, and the stress borne by each rigid linkage device 4 can be reduced, further improving the stability and reliability of the entire laminating machine; or in the length direction of the laminating unit 3, at least two rigid linkage devices 4 are arranged along the length direction of the laminating unit 3, and in the width direction of the laminating unit 3, there are also at least two rigid linkage devices 4, and at least two rigid linkage devices 4 are respectively arranged on both sides of the width direction of the laminating unit 3. Through the above arrangement, the stability and reliability of multiple laminating units 3 during opening and closing movements can be improved, and the stress borne by each rigid linkage device 4 can be reduced, further improving the stability and reliability of the entire laminating machine.

[0104] Continue to refer to Figures 4 to 6As shown, in some embodiments, the rigid linkage device 4 also includes a connecting rod 42, and the two ends of the connecting rod 42 are respectively connected to two adjacent rigid linkage devices 4 arranged along the length direction of the laminating unit 3 through connecting parts. It should be noted that all rigid linkage devices 4 are parallel to each other; specifically, the two ends of the connecting rod 42 can be respectively rotatably matched with the second ends of two adjacent transmission arms 41 located on the same side of the laminating unit 3 in the width direction and arranged in the length direction. At this time, the first ends of the two transmission arms 41 are rotationally connected to the frame 1 or the fixed laminating unit through the rotating part 411; through the connecting rod 42, it is possible to ensure that the second ends of the two transmission arms 41 form a stable connection, and use the connecting rod 42, the two transmission arms 41 and part of the frame 1 or part of the fixed laminating unit to form a parallelogram structure, ensuring that the two transmission arms 41 can always remain in a parallel state, and at the same time, the movement of the two transmission arms 41 can also be kept synchronized.

[0105] In some embodiments, the movable part 412 can be a slide provided on the rigid linkage device 4, and the laminating unit 3 is movably connected to the slide through a slider or a roller; or a slide groove is provided on the laminating unit 3, and the movable part 412 can be a slider or a roller provided on the rigid linkage device 4; it should be understood that the rigid linkage device 4 can slide relative to the laminating unit 3 through the movable part 412, and the sliding mentioned in this application includes the form of a slider rail 6 or a roller slide. The connection method of the slider rail or the roller slide avoids the occurrence of dead points at the connection between the rigid linkage device 4 and the laminating unit 3, and avoids the deformation of the laminating unit 3 under the working action of the rigid linkage device 4 and the driving device 2; in other embodiments, the rigid linkage device 4 can also be connected to the laminating unit 3 through a hinge or other more flexible connecting part.

[0106] In some embodiments, the driving device 2 includes one or more of a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, and a linear motor; the transmission arm 41 is hinged to the driving end of the driving device 2, or the transmission arm 41 is connected to the driving end of the driving device 2 through a connecting piece, which can be a plate or a rod; or one of the two lamination units 3 is connected to the driving end of the driving device 2, and the frame 1 is connected to the fixed end of the driving device 2. The driving device 2 drives the lamination unit 3 to move, and the lamination unit 3 drives the transmission arm 41 to swing, and the remaining lamination units 3 on the transmission arm 41 also move under the drive of the transmission arm 41, thereby realizing the closing or opening of adjacent lamination units 3; the driving device 2 can also include a rotating motor, the driving end of the driving device 2 is connected to the rotating part 411, and the fixed end of the driving device 2 is connected to the frame 1; of course, a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a linear motor can be connected to one end of the transmission arm 41 to drive the transmission arm 41 to swing, and a rotating motor is also provided to connect the rotation point of the transmission arm 41 to drive the transmission arm 41 to rotate.

[0107] Continue to refer to Figure 1 and Figure 2 As shown, the laminating machine further includes a guide rail 5, which is fixedly mounted on the frame 1 and extends along the movement direction of the laminating unit 3. The laminating unit 3 is slidably fitted with the guide rail 5. Specifically, referring to Figure 4 、 Figure 5 and Figure 8 As shown, the laminating unit 3 can roll with the guide rail 5 through the guide wheel 31, so as to reduce the friction between the laminating unit 3 and the guide rail 5. The guide wheel 31 can be specifically arranged on the laminating unit 3, and multiple guide wheels 31 can be arranged on the guide rail 5 along its extension direction, wherein the peripheral side of the guide wheel 31 can be provided with a guide groove opened along its rotation direction, and the guide groove can be used to limit the guide rail 5 or the side of the laminating unit 3 in the axial direction of the guide wheel 31; further, the laminating unit 3 can slide with the guide rail 5 through a slider sleeved on the guide rail 5, and can form a limit in any direction other than the extension direction of the guide rail 5 between the laminating unit 3 and the guide rail 5, thereby further ensuring that the laminating unit 3 will always move along the extension direction of the guide rail 5; through the setting of the guide rail 5, the support points for the laminating unit 3 can also be increased, thereby improving the stability and reliability of the laminating unit 3 during movement.

[0108] In some embodiments, the guide rail 5 extends along the thickness direction of the laminating unit 3, and the laminating unit 3 is provided with a slide rail 6 extending along its length direction. The thickness direction and the width direction are both perpendicular to the length direction, and the movable part 412 is slidably set on the slide rail 6 corresponding to it along the length direction; it should be understood that the extension direction of the guide rail 5 is perpendicular to the plane where the laminating unit 3 is located. At this time, the sliding cooperation between the laminating unit 3 and the transmission arm 41 can be achieved through the slide rail 6, avoiding the dead point of the transmission arm 41 when it swings due to the setting of the guide rail 5. Specifically, when the transmission arm 41 rotates around the rotating part When 411 rotates, all movable parts 412 start to slide along the slide rail 6 on the laminating unit 3 connected thereto. When the transmission arm 41 rotates to a set angle, the farther the movable part 412 is from the rotating part 411, the greater the relative sliding distance between the laminating unit 3 connected thereto. All laminating units 3 (except the fixed laminating unit) start to rise or fall synchronously under the guidance of the guide rail 5. During the whole process, the laminating units 3 will not be misaligned in the thickness direction. All laminating units 3 always maintain vertical movement, thereby effectively reducing the space occupied by the entire laminating machine. At the same time, if Figure 3 As shown, multiple racks 1 can be stacked more conveniently.

[0109] In one implementation, the movable portion 412 may be a roller, and the slide rail 6 and the roller may roll relative to each other.

[0110] At this time, the driving end of the driving device 2 can reciprocate along the thickness direction of the laminating unit 3, and the driving end of the driving device 2 can be fixedly connected to the driving connection member 32 on one of the laminating units 3. Specifically, refer to Figure 4 、 Figure 5 and Figure 8 As shown, the driving connection 32 can be set at the bottom of the support plate 9, and the rotating part 411 of the transmission arm 41 can be set at the top and rotated with the frame 1, or rotated with the fixed laminating unit 3 fixedly set on the frame 1; it should be understood that in this embodiment, the driving end of the driving device 2 can only be against the driving connection 32 in the thickness direction of the laminating unit 3 (in the direction of gravity), that is, the driving end of the driving device 2 only needs to push the driving connection 32 to move upward to complete the synchronous closing of all the laminating units 3. When all the laminating cavities need to be opened, it is only necessary to slowly move the driving end of the driving device 2 downward, and the bottom laminating unit 3 will slowly move downward following the driving end of the driving device 2 under the action of gravity until the bottom laminating unit 3 is unfolded into place, at which time the driving end of the driving device 2 can stop moving.

[0111] Preferably, the number of guide rails 5 can be two, and the two guide rails 5 are respectively arranged at the two ends of the lamination unit 3 in the length direction. The number of guide rails 5 can also be greater than two, and at least three guide rails 5 can be evenly arranged along the length direction of the lamination unit 3 or along the circumference of the lamination unit 3.

[0112] Of course, as the length of the laminating unit 3 increases, the number of guide rails may also be 4, 5, 6 or more.

[0113] In a further embodiment, the length of the slide rail 6 close to the rotating part 411 is shorter than the length of the slide rail 6 away from the rotating part 411; because when the transmission arm 41 rotates to a set angle, the farther the movable part 412 is from the rotating part 411, the greater the relative sliding distance between the laminating unit 3 connected thereto and the movable part 412, so this setting is more reasonable, and the length of the slide rail 6 at different positions is reasonably set according to the relative sliding distance between each layer of laminating unit 3 and the movable part 412; thereby reducing costs, and at the same time, all movable parts 412 can reach one end of the slide rail 6 corresponding to it at the same time, so that all slide rails 6 can simultaneously abut and limit all movable parts 412.

[0114] In some embodiments, the slide rail 6 is arranged on the side or bottom of the laminating unit 3, the movable part 412 is a roller, and the laminating unit 3 is placed on the movable part 412. When the transmission arm 41 swings, the roller rotates along the slide rail 6, while supporting the laminating unit 3 to rise or fall.

[0115] In some embodiments, laminating the photovoltaic module 8 using the above-mentioned laminator specifically includes the following steps:

[0116] S1. Control the driving end of the driving device 2 to drive the transmission arm 41 to rotate around the rotating part 411, so that the angle between the transmission arm 41 and the laminating unit 3 in the thickness direction gradually becomes smaller, thereby increasing the spacing between every two adjacent movable parts 412 in the thickness direction of the laminating unit 3; the transmission arm 41 drives the laminating units 3 connected to it to change their positions in the first direction through the movable part 412, and the spacing between every two adjacent laminating units 3 in the first direction gradually increases until the driving end of the driving device 2 moves into place, thereby realizing the synchronous opening of the laminating cavity formed between every two adjacent laminating units 3;

[0117] S2, controlling the driving end of the driving device 2 to drive the transmission arm 41 to rotate around the rotating portion 411 in the opposite direction to that in step S1, so that the angle between the transmission arm 41 and the thickness direction of the laminating unit 3 gradually increases, thereby reducing the distance between every two adjacent movable portions 412 in the first direction;

[0118] The transmission arm 41 drives the lamination unit 3 connected to it to change its position in the first direction through the movable part 412, and the distance between each two adjacent lamination units 3 in the first direction gradually becomes smaller until the driving end of the driving device 2 moves into place, thereby realizing the synchronous closing of the lamination cavity formed between each two adjacent lamination units 3.

[0119] Continue to refer to Figure 20 As shown, in some embodiments, Figure 20 The direction of the middle arrow is the conveying direction of the photovoltaic module 8. The laminator also includes a loading conveyor line 71 and an elevator 72. The conveying height of the loading conveyor line 71 is aligned with the position height of the middle layer of the multi-layer lamination unit 3 in the thickness direction. The elevator 72 is located between the loading conveyor line 71 and the lamination unit 3, and is used to transfer the photovoltaic module 8 on the loading conveyor line 71 to one of the lamination units 3.

[0120] In one implementation, the laminator also includes a storage area, which is arranged between the elevator 72 and the laminating unit 3; the storage area includes multiple layers of storage racks, and each layer of storage racks is arranged corresponding to one layer of laminating unit 3; the elevator 72 is used to transfer the photovoltaic components 8 on the loading conveyor line 71 to the multiple layers of storage racks, and the multiple layers of storage racks simultaneously convey the stored photovoltaic components 8 to the corresponding laminating units 3.

[0121] In one implementation, the multi-layer storage rack includes a frame body, in which a plurality of conveying devices are arranged in sequence from top to bottom, each conveying device corresponds to a layer of lamination unit 3, and the conveying device includes a conveyor belt and a conveyor belt driving device. The conveyor belt is used to carry and transport photovoltaic components 8, and the driving device 2 is used to drive the conveyor belt to rotate.

[0122] The setting of the storage area enables advance caching and overall feeding of the photovoltaic modules 8 , thereby avoiding the situation where the photovoltaic modules 8 in different lamination units 3 are heated inconsistently when feeding a single material to the lamination unit 3 .

[0123] Specifically, the laminating machine can be loaded through the following steps:

[0124] S11, adjusting the loading conveyor line 71 and the elevator 72 to the position of the middle layer of the multi-layer laminating unit 3 in the first direction; if the number of laminating units 3 is an odd number, the loading conveyor line 71 and the elevator 72 are flush with the middle layer; if the number of laminating units 3 is an even number, the loading conveyor line 71 and the elevator 72 are aligned with the middle position of the two middle layers;

[0125] S12, the elevator 72 sequentially or randomly transfers the photovoltaic modules 8 on the loading conveyor line 71 to a storage rack with an empty storage area;

[0126] S13 , the storage racks simultaneously convey the stored photovoltaic modules 8 to their respective corresponding lamination units 3 ; it should be noted that the photovoltaic modules 8 on the loading conveyor line 71 can also be directly transferred to the lamination units 3 using the elevator 72 .
