[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0024] In the embodiment of the present application, a conveying device for a solar cell assembly is provided, referring to Figure 1 and Figure 2The conveying equipment of the solar cell assembly is used to transport the cover plate 3 coated with the adhesive film 30, which includes a conveyor frame; a conveyor belt, which is rotatably installed on the conveyor frame to carry the cover plate 3; a fixing device, which is used to fix the cover plate 3 coated with the adhesive film 30 on the conveyor belt; a smoothing mechanism 5, which is used to clean and smooth the adhesive film 30 coated on the cover plate 3; the conveyor frame includes a first conveyor frame 11, a second conveyor frame 12 and a driving mechanism 6, the driving mechanism 6 is used to drive the second conveyor frame 12 to rotate around a first axis relative to the first conveyor frame 11 between a first position and a second position, in the first position, the second conveyor frame 12 is flush with the first conveyor frame 11; in the second position, the second conveyor frame 12 is inclined with the first conveyor frame 11; when the second conveyor frame 12 rotates to the second position, the smoothing mechanism 5 cleans and smoothes the adhesive film 30 coated on the cover plate 3. In this way, the adhesive film 30 can be cleaned and smoothed, avoiding fragments of the cell sheets laid on the adhesive film 30 and the situation in which the solar cell assembly is scrapped due to the cover plate 3 being broken during lamination; and, when the second conveyor rack 12 is tilted, that is, when the cover plate 3 is tilted, the adhesive film 30 is smoothed and cleaned. At this time, foreign matter on the adhesive film 30 is easier to clean, and wrinkles on the adhesive film 30 are easier to smooth out, so that the cleaning and smoothing effect of the adhesive film 30 is better.

[0025] In practice, solar cell modules are produced in an assembly line in a solar cell module manufacturing system. The production sequence of solar cell modules is usually to place a cover plate 3 (usually glass), apply adhesive film, apply solar cells, apply adhesive film again, and apply backplane. The conveying equipment of the solar cell module is used to transport the cover plate 3 with the adhesive film 30 applied. In practice, the conveying equipment of the solar cell module includes a conveyor belt and a conveyor frame. The conveyor belt is rotatably mounted on the conveyor frame, that is, the conveyor belt can circulate on the conveyor frame. The cover plate 3 is placed on the conveyor belt, that is, the conveyor belt can carry the cover plate 3 and drive the cover plate 3 to flow to the corresponding work station. In practice, the cover plate 3 with the adhesive film 30 is fixed to the conveyor belt by a fixing device to prevent the conveyor belt from shaking during the flow process, so that the cover plate moves from the placement position or even slides off the conveyor belt, affecting the manufacturing progress of the solar cell module.

[0026] Specifically, if Figure 1 and Figure 2 As shown, the conveying frame includes a first conveying frame 11, a second conveying frame 12 and a driving mechanism 6. The driving mechanism 6 can drive the second conveying frame 12 to rotate between a first position and a second position relative to the first conveying frame 11 around a first axis, wherein the second conveying frame 12 and the first conveying frame 11 can be connected by a pivot shaft, and the first axis is the axis of the pivot shaft.

[0027] Specifically, if Figure 1As shown, in the first position, the second conveying rack 12 is flush with the first conveying rack 11, and the second conveying rack 12 is in a horizontal state. Figure 2 As shown, the second conveyor rack 12 is tilted relative to the first conveyor rack 11, and the second conveyor rack 12 is in an inclined state. In practice, when the second conveyor rack 12 rotates to the second position, that is, when the second conveyor rack 12 is in an inclined state, the smoothing mechanism 5 cleans and smoothes the adhesive film 30 applied to the cover plate 3. This makes it easier to clean foreign matter on the adhesive film 30 and smooth out wrinkles on the adhesive film 30, thereby achieving better cleaning and smoothing effects on the adhesive film 30. This also prevents fragmentation of solar cells applied to the adhesive film 30 and avoids the possibility of the cover plate 3 being broken during lamination, which could result in the solar cell assembly being scrapped.

[0028] It should be noted that, in the second position, the inclination angle of the second conveyor rack 12 relative to the first conveyor rack 11 can range from [40°, 70°], preferably 50°. This embodiment does not limit the specific setting of the inclination angle, and it can be set according to actual conditions.

[0029] In the embodiments of this application, Figure 1 and Figure 2 As shown, the conveying rack also includes a third conveying rack 13, referring to Figure 3 The smoothing mechanism 5 may include: a first driving component 51 and a mounting bracket 52; a cleaning member 53 and a smoothing member 54 are provided on the mounting bracket 52; the first driving component 51 is installed on the third conveying rack 13, and is used to drive the mounting bracket 52 to drive the cleaning member 53 and the smoothing member 54 to move on the film 30 to clean and smooth the film 30.

[0030] Specifically, if Figure 3 As shown, the mounting bracket 52 is U-shaped and includes two opposing and spaced-apart side panels 521, and a connecting plate 522 connecting one end of each side panel 521. A cleaning member 53 is mounted on the surface of the connecting plate 522 opposite the film 30. A smoothing member 54 is connected to the other end of each side panel 521. Thus, the smoothing member 54 and the mounting bracket 52 form a rectangular frame.

[0031] Specifically, the cleaning member 53 is typically a brush. The length of the brush is greater than or equal to the length of the film 30, so that the brush can clean every area of ​​the film 30, ensuring that all foreign matter on the film 30 is removed. The brush can be any of a brush roller, a wire brush, a strip brush, and a nylon brush, and this embodiment is not limited to this, and the specific selection can be based on actual circumstances. The brush is composed of multiple brush filaments, and the brush filaments can be any of wool, horsehair, nylon, and polypropylene, and can be set according to actual needs. This embodiment is not limited to this.

[0032] Specifically, the smoothing member 54 is a cylindrical structure or a plate structure. In order to ensure that the smoothing member 54 does not damage the film 30 during the process of smoothing the film 30, the smoothing member 54 of this embodiment is fixed with a plastic material with good wear resistance at least in the area in contact with the film 30. The plastic material can be fixed to the smoothing member 54 by bonding or integral molding.

[0033] Specifically, if Figure 2 As shown, when the second conveyor frame 12 rotates to the second position, the first driving assembly 51 drives the mounting bracket 52 to drive the cleaning member 53 and the smoothing member 54 to move on the adhesive film 30 to clean and smooth the adhesive film 30.

[0034] It is worth noting that, in the direction in which the mounting bracket 52 moves from a high position to a low position along the tilt direction of the adhesive film 30, as shown in FIG. Figure 3 As shown, the cleaning member 53 is located in front of the smoothing member 54, that is, the cleaning member 53 is away from the left end of the film 30. In other words, the foreign matter on the film 30 is cleaned first, and then the wrinkled film 30 is smoothed to avoid scratching the film 30 by smoothing and crushing the foreign matter first.

[0035] It should be noted that the smoothing mechanism 5 moves from a high position to a low position along the tilt direction of the film 30 at least once until the foreign matter is removed and the film 30 is smoothed. In practice, as the second conveyor frame 12 rotates from the first position to the second position, some of the foreign matter on the film 30 can slide freely off the film 30, reducing the amount of cleaning required by the smoothing mechanism 5 and thereby improving work efficiency.

[0036] In the embodiment of the present application, the first driving component 51 includes: a first driving member 511; the third conveying rack 13 includes a third bracket 132; the first driving member 511 is a first cylinder, the cylinder barrel of the first cylinder is obliquely installed on the third bracket 132, and can rotate relative to the third bracket 132, the piston of the first cylinder is fixedly connected to the mounting bracket 52, and the piston of the first cylinder is used to drive the mounting bracket 52 to move on the film 30.

[0037] In practical applications, a cylinder usually includes a cylinder barrel and a piston, and the piston can extend or retract into the cylinder barrel. Figure 1 and Figure 2As shown, the third conveyor rack 13 includes a third bracket 132 and a third working platform 131 installed above the third bracket 132. The cylinder barrel of the first cylinder is installed obliquely on the third bracket 132. In order to facilitate the adjustment of the third bracket 132, the cylinder barrel of the first cylinder is rotatably connected to the third bracket 132, that is, the cylinder barrel of the first cylinder can rotate relative to the third bracket 132. When the second conveyor rack 12 is rotated to the second position, the cylinder barrel of the first cylinder can rotate in a small range so that the piston of the first cylinder is located above the film 30 and parallel to the film 30. At this time, the cleaning member 53 and the smoothing member 54 on the mounting bracket 52 are not in contact with the film 30. When the piston of the first cylinder drives the mounting bracket 52 to move to the left end of the film 30 (from the left end). Figures 1 to 2 ), the cylinder barrel of the first cylinder rotates counterclockwise so that the cleaning member 53 and the smoothing member 54 are in contact with the film 30. Then, the movement of the piston of the first cylinder can drive the mounting bracket 52 to drive the cleaning member 53 and the smoothing member 54 to move from the left end to the right end of the film 30 to clean foreign matter dropped on the film 30 and smooth out the wrinkles of the film 30.

[0038] It should be noted that if Figure 1 As shown, the piston of the first cylinder is retracted into the cylinder, which is the initial state to avoid affecting the rotation of the second conveying rack 12 to the second position; Figure 2 In the process, the piston of the first cylinder extends out of the cylinder barrel to drive the mounting bracket 52 to move to the left end of the film 30.

[0039] It should also be noted that, in addition to a pneumatic cylinder, the first drive member 511 can also be a combination of a linear motor and a rotary motor. In this case, a telescopic rod is added between the linear motor and the mounting bracket 52. The rotary motor is connected to the telescopic rod to drive the telescopic rod to rotate, so that the telescopic rod drives the mounting bracket 52 to be positioned above and parallel to the film 30. The linear motor is connected to one end of the telescopic rod, and the other end of the telescopic rod is connected to the mounting bracket 52. The linear motor drives the telescopic rod to extend and retract, thereby driving the mounting bracket 52 to move, and in turn, driving the cleaning member 53 and the smoothing member 54 to move on the film 30.

[0040] Specifically, for the convenience of installation and disassembly, the first driving member 511 is detachably connected to the third bracket 132, wherein the detachable connection can be achieved by fasteners (such as bolts, screws, etc.), and the specific fasteners can be selected according to actual conditions.

[0041] In an embodiment of the present application, the first drive assembly 51 also includes: a second drive member 512; the second drive member 512 is installed on the third bracket 132, and the second drive member 512 is connected to the cylinder barrel of the first cylinder to drive the cylinder barrel of the first cylinder to deflect, so that when the second conveying rack 12 rotates to the second position, the piston of the first cylinder is located on the film and parallel to the film 30.

[0042] Specifically, for the convenience of installation and disassembly, the second driving member 512 is detachably connected to the third bracket 132, wherein the detachable connection can be achieved by fasteners (such as bolts, screws, etc.), and the specific fasteners can be selected according to actual conditions.

[0043] Specifically, the second driving member 512 mainly drives the cylinder of the first cylinder to deflect, thereby causing the piston of the first cylinder to drive the mounting bracket 52 to deflect. The second driving member 512 can be a linear motor or a cylinder. Due to the easy installation and maintenance of the cylinder and the simple structure, the cylinder is preferably used in this embodiment (the cylinder is referred to as the second cylinder). For example, Figure 2 As shown, the cylinder barrel of the second cylinder is installed on the third bracket 132, and the second cylinder is located below the first cylinder. The piston of the second cylinder is fixedly connected to the cylinder barrel of the first cylinder. The movement of the piston of the second cylinder can drive the cylinder barrel of the first cylinder to deflect along its own axis, thereby driving the piston of the first cylinder to deflect, and then driving the mounting bracket 52 to deflect, so that the cleaning member 53 and the smoothing member 54 on the mounting bracket 52 can be located above the film 30 and parallel to the film 30, and can also drive the first cylinder to rotate so that the cleaning member 53 and the smoothing member 54 are in contact with the film, ensuring the reliability of cleaning and smoothing the film 30.

[0044] In the examples of this application, refer to Figure 4 The smoothing mechanism 5 also includes: two supporting structures 55; the two supporting structures 55 are symmetrically arranged on the mounting bracket 52, and each supporting structure 55 can rotate and move relative to the third bracket 132.

[0045] Specifically, if Figure 4As shown, taking the first driving member 511 as a first cylinder as an example, the two support structures 55 are symmetrical relative to the first cylinder, and each support structure 55 is fixedly connected to the mounting bracket 52. Since the support structures 55 can rotate and move relative to the third bracket 132, in practice, when the cylinder body of the first cylinder deflects, the piston of the first cylinder drives the mounting bracket 52 to deflect, and at the same time drives each support structure 55 to rotate relative to the third bracket 132; when the piston of the first cylinder moves, the mounting bracket 52 moves, and at the same time, the support structures 55 also move relative to the third bracket 132. In this way, this embodiment can make the mounting bracket 52 more stable during rotation and movement, thereby ensuring the position of the mounting bracket 52, and thus ensuring that the cleaning member 53 and the smoothing member 54 can move on the film 30.

[0046] In the embodiments of this application, Figure 4 As shown, the support structure 55 includes: a sliding rod 551, a slider 552 and a fixed block 553; the fixed block 553 is fixed to the third bracket 132, and the slider 552 is rotatably connected to the fixed block 553; the slider 552 is provided with a sliding groove adapted to the sliding rod 551, and the sliding rod 551 is slidably set in the sliding groove. When the first driving member 511 drives the mounting bracket 52 to move, the sliding rod 551 slides in the sliding groove.

[0047] Specifically, if Figure 4 As shown, the fixing block 553 can be fixedly connected to the third bracket 132 by any of bonding, welding, fasteners, etc. The slider 552 is rotatably connected to the fixing block 553, that is, the slider 552 can rotate relative to the fixing block 553. The slider 552 is provided with a slot that matches the slide rod 551. The slide rod 551 slides within the slot, and the rotation of the slider 552 drives the slide rod 551 to rotate. When the cylinder body of the first cylinder deflects, the piston of the first cylinder drives the mounting bracket 52 to deflect, and simultaneously drives the slide rod 551 to rotate relative to the fixing block 553. When the piston of the first cylinder moves, the mounting bracket 52 moves, and the slide rod 551 slides within the slot. The cross-sectional shape of the slot can be any of "T"-shaped, rectangular, arc-shaped, and irregular, and the cross-sectional shape of the slide rod 551 is compatible with the cross-sectional shape of the slot.

[0048] In the embodiments of this application, Figure 4 As shown, the support structure 55 further includes: a first rotating shaft 554 ; the slider 552 is rotatably connected to the fixed block 553 via the first rotating shaft 554 .

[0049] Specifically, one end of the first rotating shaft 554 is fixedly connected to the fixed block 553. In practice, the fixed block 553 may be provided with a first mounting hole, and one end of the first rotating shaft 554 passes through the first mounting hole. One end of the first rotating shaft 554 and the first mounting hole have a transition fit or an interference fit, that is, the first rotating shaft 554 does not move relative to the first mounting hole. The other end of the first rotating shaft 554 is rotatably connected to the slider 552. In practice, the slider 552 may be provided with a second mounting hole, and the other end of the first rotating shaft 554 passes through the second mounting hole. The other end of the first rotating shaft 554 has a clearance fit with the wall of the second mounting hole, that is, the slider 552 can rotate about the first rotating shaft 554. Among them, the second mounting hole can be a smooth hole or a threaded hole, and the structure of the matching part of the first rotating shaft 554 and the second mounting hole is adapted to the structure of the hole wall. For example, if the second mounting hole is a threaded hole, that is, a first thread is provided on the hole wall of the second mounting hole, and the matching part of the first rotating shaft 554 and the second mounting hole is provided with a second thread, and the second thread matches the first thread.

[0050] In the embodiments of this application, Figure 1 and Figure 2 As shown, the fixing device includes: a clamping mechanism 4, the second conveyor frame 12 includes a second work surface 121, the clamping mechanism 4 is rotatably connected to the first conveyor frame 11 to clamp one end of the cover plate 3 coated with the adhesive film 30 or release the clamping of one end of the cover plate 3 coated with the adhesive film 30; the driving mechanism 6 is used to drive the second work surface 121 to rotate relative to the first conveyor frame 11 between a first position and a second position.

[0051] It should be noted that, in order not to affect the placement of the cover plate 3 on the corresponding conveyor belt on the second work surface 121, the initial state of the pressing mechanism 4 is: the pressing mechanism 4 releases the pressing of the cover plate 3. Figure 1 As shown, the pressing mechanism 4 is rotatably connected to the second work surface 121, that is, the pressing mechanism 4 can rotate relative to the second work surface 121. In practice, when the conveyor belt drives the cover plate 3 coated with the adhesive film 30 to flow onto the second work surface 121, the pressing mechanism 4 can rotate to a position where it abuts against one end (the left end in the figure) of the cover plate 3 coated with the adhesive film 30, thereby pressing the left end of the cover plate 3 coated with the adhesive film 30. At this time, the pressing mechanism 4 switches from the initial state to the pressing state.

[0052] Specifically, the driving mechanism 6 drives the second working surface 121 of the second conveying frame 12 to rotate relative to the first conveying frame 11 around the first axis between the first position and the second position. Figure 1 As shown, in the first position, the second work surface 121 is flush with the first conveying rack 11, and the second work surface 121 is in a horizontal state. Figure 2As shown, the second working surface 121 is inclined with respect to the first conveying rack 11 , and the second working surface 121 is in an inclined state.

[0053] In the embodiments of this application, Figure 1 and Figure 2 As shown, the fixing device further includes: a limiting mechanism 2; the limiting mechanism 2 is connected to the second work surface 121 and can move relative to the second work surface 121 in the vertical direction to limit the other end of the cover plate 3 coated with the adhesive film 30.

[0054] Specifically, the initial position of the limiting mechanism 2 is: the limiting mechanism 2 is located below the cover plate 3 to prevent the limiting mechanism 2 from damaging the cover plate 3 when the conveyor belt drives the cover plate 3 to rotate onto the second work surface 121. Figure 1 As shown, the limiting mechanism 2 is connected to the second work surface 121 and is movable in the vertical direction relative to the second work surface 121. After the cover plate 3 is positioned on the second work surface 121, the limiting mechanism 2 moves upward relative to the second work surface 121 to a target height above the cover plate 3 coated with the adhesive film 30, thereby limiting the other end of the cover plate 3 (the right end in the figure). At this time, the limiting mechanism 2 moves from the initial position to the limiting position to prevent the cover plate 3 coated with the adhesive film 30 from sliding off the second conveyor rack 12.

[0055] In the examples of this application, refer to Figure 5 The limiting mechanism 2 includes a limiting rod 21 and a third driving member 22; the third driving member 22 is installed on the second work surface 121 and connected to the limiting rod 21. The third driving member 22 is used to drive the limiting rod 21 to move in the vertical direction so that the limiting rod 21 limits the other end of the cover plate 3 coated with the adhesive film 30.

[0056] Specifically, if Figure 5 As shown, since the second work surface 121 is to be rotated in the clockwise direction, that is, the right end of the second work surface 121 is tilted downward, in order to prevent the cover 3 on the second work surface 121 from sliding off, a limiting rod 21 is provided in this embodiment. Figure 1 As shown, the limiting rod 21 is close to the right end of the second working table 121. The conveying device of the solar cell assembly of this embodiment includes at least one limiting mechanism, Figure 5 Two limiting mechanisms are shown in the figure. Of course, this embodiment can also be provided with other numbers of limiting mechanisms, for example, 3, 4 or 5. The specific number can be set according to actual conditions.

[0057] Specifically, if Figure 5 As shown, the third driving member 22 is connected to the limiting rod 21, and the third driving member 22 can drive the limiting rod 21 to move in the vertical direction ( Figure 1In order to prevent the cover plate 3 from being damaged by the limiting rod 21 when the conveyor belt drives the cover plate 3 to rotate onto the second work surface 121, and to prevent the limiting rod 21 from damaging the cover plate 3, the initial position of the limiting rod 21 in this embodiment is as follows: the limiting rod 21 is located below the cover plate 3, that is, the limiting rod 21 is lower than the surface of the cover plate 3 in contact with the second work surface 121. After the conveyor belt drives the cover plate 3 to rotate onto the second work surface 121, the third driving member 22 drives the limiting rod 21 upward to a height higher than the cover plate 3 coated with the adhesive film 30, thereby limiting the right end of the cover plate 3 to prevent the cover plate 3 from sliding off the second conveyor rack 12. At this time, the limiting rod 21 switches from the initial position to the limiting position.

[0058] It should be noted that if Figure 5 As shown, the third driving member 22 is installed on the second work surface 121 of the second conveying rack 12. In order to facilitate the installation and disassembly of the third driving member 22, the third driving member 22 is detachably installed on the second work surface 121. In this way, the moving distance of the limiting rod 21 can also be reduced, the limiting efficiency can be improved, and thus the manufacturing efficiency of the solar cell module can be improved.

[0059] In the embodiments of this application, Figure 5 As shown, the third driving member 22 is a third cylinder; the piston of the third cylinder is connected to the limiting rod 21, and the piston of the third cylinder is used to drive the limiting rod 21 to move in the vertical direction.

[0060] Specifically, if Figure 5 As shown, due to the advantages of easy installation and maintenance and a simple structure, the third driving member 22 of this embodiment is preferably a pneumatic cylinder (herein referred to as the third cylinder). The barrel of the third cylinder is detachably connected to the second work surface 121, and the piston of the third cylinder is connected to the limiting rod 21. When the piston of the third cylinder extends from the barrel, it drives the limiting rod 21 upward, so that the limiting rod 21 moves to a height higher than the cover plate 3 coated with the adhesive film 30, thereby limiting the right end of the cover plate 3. Conversely, when the piston of the third cylinder retracts into the barrel, it drives the limiting rod 21 downward, restoring the initial state.

[0061] It should be noted that the third driving member 22 can also be a linear motor connected to the limiting rod 21 to drive the limiting rod 21 to move in the vertical direction. The height of the limiting rod 21 is greater than the sum of the thicknesses of the cover plate 3 and the adhesive film 30, so that the limiting rod 21 can limit the position of the cover plate 3 with the adhesive film 30 applied.

[0062] In the examples of this application, refer to Figure 1 、 Figure 2 and Figure 6As shown, the clamping mechanism 4 includes: a fourth driving member 41 and a pressure block 42, the first conveying frame 11 includes a first bracket 112 and a first work surface 111 provided on the first bracket 112; the fourth driving member 41 is installed on the second work surface 121, and the fourth driving member 41 is connected to the pressure block 42 to drive the pressure block 42 to rotate so that the pressure block 42 presses one end of the cover plate 3 coated with the adhesive film 30 or releases the pressure on one end of the cover plate 3 coated with the adhesive film 30; the driving mechanism 6 is installed on the first bracket 112 to drive the second work surface 121 to rotate relative to the first work surface 111 between a first position and a second position.

[0063] Specifically, if Figure 1 and Figure 2 As shown, the fourth driving member 41 is detachably mounted on the second work surface 121, facilitating installation and removal of the fourth driving member 41. The fourth driving member 41 is connected to the pressing block 42 and is configured to drive the pressing block 42 to rotate. Specifically, the fourth driving member 41 can drive the pressing block 42 toward the cover plate 3 to compress the end of the cover plate 3 coated with the adhesive film 30, or move the pressing block 42 away from the cover plate 3 to release the pressure on the end of the cover plate 3 coated with the adhesive film 30. Figure 1 、 Figure 2 and Figure 6 It is shown that the pressing block 42 presses one end of the cover plate 3 on which the adhesive film 30 is applied. Figure 5 It is shown that the pressing block 42 releases the pressing of the end of the cover plate 3 coated with the adhesive film 30 , that is, the pressing block 42 does not press the end of the cover plate 3 coated with the adhesive film 30 .

[0064] like Figure 1 and Figure 2 As shown, the pressing block 42 is positioned near the left end of the second work surface 121, primarily compressing the left end of the cover plate 3 and the left end of the film 30. This prevents the film 30 from moving when the cleaning member 53 and the smoothing member 54 move from the left end to the right end of the film 30. To prevent damage to the film 30 caused by the pressing block 42 when compressing it, a flexible layer is fixedly provided at least in the area where the pressing block 42 contacts the film 30. The flexible layer can be made of any of rubber, silicone, plastic, or other flexible materials.

[0065] Specifically, the driving mechanism 6 is used to drive the second working surface 121 to rotate relative to the first working surface 111 around the first axis between the first position and the second position. Figure 1 As shown, in the first position, the second work surface 121 is flush with the first work surface 111, and the second work surface 121 is in a horizontal state. Figure 2As shown, the second work surface 121 is tilted relative to the first work surface 111. The second work surface 121 is in a tilted state. The fourth driving member 41 can be any one of a motor, a cylinder, and other driving sources. The specific choice can be made according to actual needs.

[0066] In the embodiments of this application, Figure 5 As shown, the clamping mechanism 4 also includes: a second rotating shaft 44 and a connecting rod 45; one end of the connecting rod 45 is fixedly connected to the pressing block 42, and the other end is fixedly connected to the second rotating shaft 44; the second rotating shaft 44 is rotatably mounted on the second work table 121, and the fourth driving member 41 is connected to the second rotating shaft 44 to drive the second rotating shaft 44 to rotate, thereby driving the pressing block 42 to rotate.

[0067] Specifically, if Figure 5 As shown, one end of the connecting rod 45 can be fixedly connected to the pressing block 42 by bonding or welding, so that the pressing block 42 and one end of the connecting rod 45 are connected together; the other end of the connecting rod 45 is fixedly connected to the second rotating shaft 44. For example, the other end of the connecting rod 45 is provided with a third mounting hole, and the second rotating shaft 44 passes through the third mounting hole and has a transition or interference fit with the third mounting hole, so that the second rotating shaft 44 is fixed in the third mounting hole. Figure 4 Two connecting rods 45 are shown in the figure. Of course, the connecting rods 45 can also be other numbers, such as 3 or more. This embodiment does not limit the specific number of connecting rods 45, and can be set according to actual needs.

[0068] Specifically, the second rotating shaft 44 can rotate relative to the second work surface 121. In practice, a fourth mounting hole can be set on the second work surface 121, and the second rotating shaft 44 passes through the fourth mounting hole and is gap-fitted with the fourth mounting hole. In this way, the second rotating shaft 44 can rotate in the fourth mounting hole to drive the connecting rod 45 to rotate, thereby driving the pressure block 42 to rotate, so that the pressure block 42 presses one end of the cover plate 3 coated with the adhesive film 30 or releases the pressure on one end of the cover plate 3 coated with the adhesive film 30. Figure 4 In the longitudinal direction of the second work surface 121 , the fourth mounting hole passes through from one end of the second work surface 121 to the other end.

[0069] In the embodiments of this application, Figure 6 As shown, the clamping mechanism 4 also includes: a connecting shaft 43, and the fourth driving member 41 is a fourth cylinder; the piston of the fourth cylinder is connected to one end of the connecting shaft 43, and the other end of the connecting shaft 43 is connected to the second rotating shaft 44. The piston of the fourth cylinder is used to drive the connecting shaft 43 to move, thereby driving the second rotating shaft 44 to rotate.

[0070] Specifically, if Figure 6As shown, the first driving member 511 is a cylinder (referred to as the fourth cylinder). The end of the piston of the fourth cylinder, which is away from the cylinder barrel, is fixedly connected to one end of a connecting shaft 43. The other end of the connecting shaft 43 is fixedly connected to the second rotating shaft 44. In practice, a fixed connection between two components means that there is no relative displacement between the two components. Common methods for achieving a fixed connection include bonding, welding, fastener connection, and clamping. The fixed connection between the connecting shaft 43 and the piston of the fourth cylinder and the second rotating shaft 44 can be any of these methods, and the specific method can be set according to actual needs.

[0071] For example, Figure 6 As shown, there is an angle between the connecting shaft 43 and the piston of the fourth cylinder. The angle is preferably 45 degrees, but can also be set to other angles, such as 50 degrees, 55 degrees, etc. The specific angle value can be set according to actual conditions and is not limited in this embodiment. Preferably, in this embodiment, a groove can be provided at the other end of the connecting shaft 43, and a protrusion structure can be provided on the second rotating shaft 44. Alternatively, a protrusion structure can be provided at the other end of the connecting shaft 43, and a groove can be provided on the second rotating shaft 44, and the protrusion structure can be embedded in the groove, so that the other end of the connecting shaft 43 is fixedly connected to the second rotating shaft 44.

[0072] In the embodiments of this application, Figure 1 and Figure 2 As shown, the driving mechanism 6 is a fifth cylinder; the cylinder barrel of the fifth cylinder is obliquely mounted on the first bracket 112, and the piston of the fifth cylinder is connected to the second work surface 121; the piston of the fifth cylinder is used to drive the second work surface 121 to rotate relative to the first work surface 111.

[0073] Specifically, the driving mechanism 6 can be a fifth cylinder, the cylinder of which is obliquely mounted on the first bracket 112 of the first conveyor rack 11 and can be located below the second work surface 121. The piston of the fifth cylinder is fixedly connected to the bottom surface of the second work surface 121, so that the fifth cylinder can support the second work surface 121 to improve the stability of the second work surface 121, and the movement of the piston of the fifth cylinder can drive the second work surface 121 to rotate relative to the first work surface 111 around the first axis, so that the second work surface 121 rotates between the first position and the second position. For example, Figure 1 This is the initial state of the fifth cylinder. The piston of the fifth cylinder extends out of its cylinder. At this time, the second working surface 121 is at the first position and is flush with the first working surface 111. When the fifth cylinder retracts into its cylinder, the second working surface 121 can be driven to rotate clockwise, as shown in FIG. Figure 2 As shown, the second working surface 121 is driven to rotate to the second position. At this time, the second working surface 121 is tilted.

[0074] Specifically, the barrel of the fifth cylinder can be rotatably connected to the first bracket 112, and the implementation method can be: the bottom of the barrel of the fifth cylinder and the first bracket 112 are rotatably connected through a connecting member, and the connecting member includes a first connecting part and a second connecting part that are rotatably connected, one end of the first connecting part is fixed to the bottom of the barrel of the fifth cylinder, one end of the second connecting part is fixed to the first bracket 112, and the other end of the first connecting part is rotatably connected to the other end of the second connecting part through a hinge or a rotating shaft.

[0075] It should be noted that pneumatic cylinders are preferred for the aforementioned drive components due to their ease of installation and maintenance, simple principle and structure, and ease of operation. In practice, the solar cell assembly conveying equipment includes a compressor and a main control system. The compressor is connected to each cylinder via a connecting air pipe to input gas into the cylinder barrel of each cylinder to extend the piston from the cylinder barrel, or to discharge gas from the cylinder barrel to retract the piston from the cylinder barrel. Furthermore, the main control system is electrically connected to the compressor to control the compressor to drive the piston of each cylinder to move. This makes the solar cell assembly conveying equipment easy to control, install, and maintain.

In this way, the film can be cleaned and smoothed, avoiding fragments of the solar cells laid on the film and the cover plate of the solar cell assembly being broken during lamination, which may cause the solar cell assembly to be scrapped; and the second conveyor rack is tilted, that is, when the cover plate is tilted, the film is smoothed and cleaned.
