Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel processing, and in particular to a packaging device for energy-absorbing photovoltaic cells. Background Art

[0002] Photovoltaic power generation is being vigorously promoted as a new type of clean energy, and photovoltaic panels are the basis of photovoltaic power generation. Photovoltaic panels are stacked with multiple layers. The structure of a general crystalline silicon solar panel is a glass panel, a film, a photovoltaic cell, a film and a backplane from top to bottom. These structures need to be packaged to form a complete crystalline silicon solar panel. A Chinese patent (Announcement No.: CN114044195A) discloses a photovoltaic panel intelligent packaging device, including a panel conveyor line, a packaging conveyor line, a pallet conveyor device, a paper shell conveyor device, a suction device and a packaging device, wherein the packaging conveyor line is arranged at one end of the panel conveyor line.

[0003] However, the existing photovoltaic panel packaging device has some disadvantages when used, such as:

[0004] The present invention can preheat the photovoltaic panels to be packaged by blowing high-temperature air before extrusion packaging of the photovoltaic panels, and can also clear dust on their surfaces. Secondly, after the photovoltaic panels to be packaged leave the extrusion packaging process, they can continue to be blown with high-temperature air to avoid rapid cooling of the film to generate bubbles.

[0005] The existing photovoltaic panel packaging device does not have the function of preheating the film. Generally, the film melting and extrusion bonding are performed simultaneously, which makes it difficult to control the temperature of the rapid melting of the film. A high temperature can easily carbonize the film, while a low temperature can easily cause incomplete melting of the film, which is not conducive to packaging. In addition, bubbles may form in the film due to the extrusion deformation of other structural layers during packaging. Summary of the invention

[0006] In view of this, the purpose of the present invention is to propose a packaging device for energy-absorbing photovoltaic cells to solve the problem that the existing photovoltaic panel packaging device does not have the function of preheating the film. Generally, the film melting and extrusion bonding are carried out at the same time, which makes it difficult to control the temperature of the rapid melting of the film. A high temperature can easily carbonize the film, while a low temperature can easily cause incomplete melting of the film, which is not conducive to packaging. In addition, during packaging, bubbles may form in the film due to extrusion deformation of other structural layers.

[0007] Based on the above purpose, the present invention provides a packaging device for energy-absorbing photovoltaic cells, comprising a mounting frame, a conveying roller rotatably arranged inside the mounting frame, a driving motor for driving the conveying roller to rotate, and a transmission belt for sequentially connecting the conveying rollers, a packaging shell is arranged above the mounting frame, a feed port is arranged on one side of the packaging shell, and a discharge port is arranged on the other side of the packaging shell, two electric heating rollers are rotatably installed inside the packaging shell, both of the two electric heating rollers are hollow structures, and air jet holes are evenly opened on the surface of the electric heating rollers, and the two electric heating rollers are located at one end of the outside of the packaging shell and are fixedly provided with a driven gear, a driving gear is meshed at the bottom of the driven gear, and the driving gear is fixedly connected to the rotating shaft inside the conveying roller;

[0008] A blower is provided at the bottom of the mounting frame, a gas output end of the blower is connected to a gas delivery pipe, and another section of the gas delivery pipe is connected to the electric heating roller;

[0009] The mounting frame is provided with a controller on the side where the driving motor is located, the signal output end of the controller is electrically connected to an electric heater connecting line, the other end of the electric heater connecting line is electrically connected to an electric heating wire, and the electric heating wire is evenly arranged inside the two electric heating rollers.

[0010] When in use, the photovoltaic cells, films and glass panels are first stacked together in sequence, and then the stacked materials are placed together on the conveying roller above the end where the feed port is located. At this time, the drive motor is started, and one of the conveying rollers is driven by the drive motor to rotate. The rotation of this conveying roller will drive all the conveying rollers to rotate synchronously through the transmission belts connected in sequence at the other end. Since one end of two of the conveying rollers is provided with a driving gear, and the driving gear is meshed with the driven gear, the rotation of the conveying roller will drive the motor through the driving gear and the driven gear. The hot pressing roller rotates, so that the photovoltaic panel to be packaged placed on the conveying roller will be conveyed into the packaging shell through the feed port, and will be squeezed and packaged when passing through the electric hot pressing roller; since the electric hot pressing roller is provided with an electric heating wire inside, before the photovoltaic panel to be packaged passes through the electric hot pressing roller, the electric heating wire is started by the controller to heat the electric hot pressing roller, and the adhesive film of the photovoltaic panel to be packaged can be melted by the high temperature of the electric hot pressing roller when the photovoltaic panel to be packaged passes through the electric hot pressing roller, and the adhesive film can be bonded between the photovoltaic cell sheet and the glass panel to achieve the packaging effect after the adhesive film is melted; secondly, the electric hot pressing roller is also One end is connected with a blower. Before the photovoltaic panels to be packaged enter the feed port, the blower is started to let the outside air flow into the electric heating roller. The air is heated by the electric heating wire inside the electric heating roller and then ejected through the air jet hole. The ejected hot air flow will flow to the feed port to preheat the photovoltaic panels to be packaged entering the feed port. At the same time, the high-speed air flow can also blow away the dust on the surface of the photovoltaic panels to be packaged, thereby cleaning the dust. Finally, since the glass panel will produce a small amount of deformation when the photovoltaic panels to be packaged are squeezed and packaged by the electric heating roller, when the photovoltaic panels to be packaged leave the extrusion packaging process, Due to the rebound of the glass panel, the glass panel and the photovoltaic cell will be separated. At this time, the adhesive film cannot fix the two after being softened by high temperature. Therefore, the separation between the glass panel and the photovoltaic cell will cause bubbles in the adhesive film, affecting the packaging effect. Therefore, when the photovoltaic panel to be packaged leaves the extrusion packaging process, the present invention continues to use the high-temperature gas sprayed by the electric heating roller to blow the adhesive film to soften it. The softened adhesive film can fill the bubbles generated by the separation between the glass panel and the photovoltaic cell, so that the packaged photovoltaic panel will not generate bubbles, and the effect is better.

[0011] By blowing high-temperature air on the photovoltaic panels to be packaged before extrusion packaging, the photovoltaic panels to be packaged can be preheated and the dust on their surface can be cleared. Secondly, after the photovoltaic panels to be packaged leave the extrusion packaging process, they can continue to be blown with high-temperature air to avoid rapid cooling of the film and the generation of bubbles.

[0012] Furthermore, the air jet holes are obliquely arranged on the surface of the electric heating pressure roller, and the opening directions of the air jet holes arranged on the surfaces of the two electric heating pressure rollers are respectively toward the feed port and the discharge port.

[0013] Among them, by tilting the jet holes on the surface of the electric heating pressure roller near the feed port toward the feed port, and tilting the jet holes on the surface of the electric heating pressure roller near the discharge port toward the discharge port, the photovoltaic panels to be packaged can be blown by high-temperature air for preheating and dust removal when entering the feed port, and the packaged photovoltaic panels can also be blown by high-temperature air when discharged from the discharge port, which can continue to soften the film and avoid the formation of bubbles inside the film.

[0014] Furthermore, a rotary joint is provided at the connection between the gas delivery pipe and the electric heating pressure roller, and the electric heating pressure roller can be rotatably connected to the gas delivery pipe through the rotary joint.

[0015] Among them, the rotary joint is a dynamic sealing connector. The air pipe is connected to the electric heating roller through the rotary joint, which can ensure the connection between the air pipe and the electric heating roller. At the same time, it can ensure that the air pipe and the electric heating roller can rotate relative to each other, so that when the electric heating roller rotates, the air pipe will not rotate with it, thereby avoiding the air pipe hindering the rotation of the electric heating roller.

[0016] Furthermore, an electric slip ring is provided at the connection between the electric heater connecting line and the electric heating pressure roller, and the electric heating pressure roller can be rotatably connected to the electric heater connecting line through the electric slip ring.

[0017] Among them, the electric slip ring is an electrical component that can make the two ends of the wire rotate while ensuring electrical connection. The electric heater connecting wire is electrically connected to the heating wire inside the electric heating roller by using the electric slip ring. When the heating wire rotates with the electric heating roller, the electric heater connecting wire will not rotate with it, thereby preventing the electric heater connecting wire from hindering the heating wire from rotating with the electric heating roller.

[0018] Furthermore, the driving motor and the blower are both electrically connected to the controller, and the controller can be used to control the power-on status of the driving motor and the blower respectively.

[0019] Furthermore, a dust removal reflux chamber is provided above the feed port, and a softening reflux chamber is provided above the discharge port. The dust removal reflux chamber is through-connected with the top of the softening reflux chamber. An air pump is installed above the packaging shell. The connection between the dust removal reflux chamber and the softening reflux chamber is through-connected with the gas input end of the air pump, and the gas output end of the air pump is through-connected with the center of the top of the packaging shell. The air pump is used to pump the gas inside one end of the dust removal reflux chamber and the top of the softening reflux chamber into the interior of the packaging shell.

[0020] Among them, by arranging the dust removal reflux chamber and the softening reflux chamber above the feed port and the discharge port, a part of the high-temperature air discharged by the electric heating roller will pass through the dust removal reflux chamber and the softening reflux chamber to flow back to the top when passing through the feed port and the discharge port, and then be pumped into the interior of the packaging shell by the air pump, so that the high-temperature air can be recovered and heat the photovoltaic panel again, further promoting the softening of the film and improving the softening efficiency of the film; at the same time, by introducing air inward from the middle of the packaging shell, the air inside the packaging shell can be promoted to flow toward the feed port and the discharge port.

[0021] Furthermore, an electric heating element is arranged at the center of the interior of the packaging shell, and the electric heating element is arranged corresponding to the gas output end of the air pump. The electric heating element is used to heat the air output by the air pump.

[0022] Since the temperature of the recovered hot air decreases during the flow process, when the recovered air is passed into the packaging shell, the recovered air is further heated by an electric heating element as needed.

[0023] Furthermore, the mounting frame is located above the two sides of the end where the feed port is located and has swing arms rotatably installed. A torsion spring is installed at the connection between the swing arm and the mounting frame. The torsion spring is used to limit the position of the swing arm. A limiting roller is vertically rotatably installed below the swing arm away from one end of the torsion spring.

[0024] Among them, since the various structural layers of the photovoltaic panels are prone to misalignment when they are placed, the structural layers of the photovoltaic panels are limited by setting limit rollers. After the stacked photovoltaic panels are placed on the conveying rollers, the stacked photovoltaic panels will be transported to the inside of the feed port by the conveying rollers. During the transportation, they will pass through the limiting rollers. If the structural layers are not placed neatly, the limiting rollers will be squeezed inward by the torsion springs between the rocker arm and the mounting frame. The unevenly placed structural layers will be straightened out through the squeezing of the limiting rollers.

[0025] Furthermore, an extrusion shell is fixedly arranged above the discharge port, the extrusion shell is arranged between the packaging shell and the softening reflux chamber, and a rubber extrusion roller is rotatably installed inside the extrusion shell.

[0026] Among them, the material of the rubber extrusion roller is soft rubber;

[0027] Since the glass panel will produce a small amount of deformation when squeezed by the electric hot pressing roller, and rebound after leaving the electric hot pressing roller to produce a cavity in the adhesive film, therefore, by setting a rubber squeezing roller, the photovoltaic panel with air in the adhesive film can be gently pressed by the soft rubber squeezing roller when passing through the rubber squeezing roller, thereby expelling the bubbles in the adhesive film and squeezing the adhesive film evenly.

[0028] Furthermore, a spring cavity is opened in the side walls at both ends of the extrusion shell, a return spring is arranged inside the spring cavity, one end of the return spring is fixedly connected to the rotating shaft inside the rubber extrusion roller, and an adjusting bolt is installed on the top of the spring cavity, and the adjusting bolt is used to adjust the extension space of the return spring.

[0029] By arranging a return spring above the rubber extrusion roller and combining it with the softness of the rubber extrusion roller, the deformation of the glass panel caused by the extrusion of the rubber extrusion roller can be avoided to the greatest extent, and bubbles can be avoided in the rubber film again; secondly, by adjusting the extension space of the return spring through the adjusting bolt, the extrusion force of the rubber extrusion roller on the glass panel can be adjusted, which is convenient for users to adjust according to needs.

[0030] Beneficial effects of the present invention: The present invention can preheat the photovoltaic panels to be packaged and clear the dust on their surface by blowing high-temperature air before extrusion packaging of the photovoltaic panels to be packaged. Secondly, after the photovoltaic panels to be packaged leave the extrusion packaging process, they can continue to be blown with high-temperature air to avoid rapid cooling of the film to produce bubbles.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a packaging device for energy-absorbing photovoltaic cells comprises a mounting frame 1, a conveying roller 201 rotatably arranged inside the mounting frame 1, a driving motor 202 for driving the conveying roller 201 to rotate, and a driving belt 203 for sequentially connecting the conveying rollers 201, a packaging shell 3 is arranged above the mounting frame 1, a feeding port 301 is arranged on one side of the packaging shell 3, and a discharging port 302 is arranged on the other side of the packaging shell 3, two electric hot pressing rollers 303 are rotatably installed inside the packaging shell 3, both of the two electric hot pressing rollers 303 are hollow structures, and jet holes 304 are evenly opened on the surface of the electric hot pressing rollers 303, and a driven gear 305 is fixedly arranged at one end of the two electric hot pressing rollers 303 located outside the packaging shell 3, and a driving gear 306 is meshed at the bottom of the driven gear 305, and the driving gear 306 is fixedly connected to the rotating shaft inside the conveying roller 201;

[0044] A blower 401 is provided at the bottom of the mounting frame 1, and a gas output end of the blower 401 is connected to a gas pipe 402, and another section of the gas pipe 402 is connected to the electric heating roller 303;

[0045] The mounting frame 1 is provided with a controller 503 on the side where the driving motor 202 is located. The signal output end of the controller 503 is electrically connected to an electric heater connection line 502. The other end of the electric heater connection line 502 is electrically connected to an electric heating wire 501. The electric heating wire 501 is evenly arranged inside the two electric heating rollers 303.

[0046] Among them, four electric heating wires 501 form a group, and multiple groups of electric heating wires 501 are evenly arranged inside the electric heating roller 303. When the blower 401 blows external air into the electric heating roller 303, the air is heated by the multiple groups of electric heating wires 501 to form high-temperature air, which is convenient for hot-melt bonding of the adhesive film inside the photovoltaic cell sheet;

[0047] When in use, the photovoltaic cell sheet, the adhesive film and the glass panel are first stacked together in sequence, and then the stacked materials are placed together on the conveying roller 201 above the end where the feed port 301 is located. At this time, the drive motor 202 is started, and the drive motor 202 is used to drive one of the conveying rollers 201 to rotate. The rotation of this conveying roller 201 will drive all the conveying rollers 201 to rotate synchronously through the transmission belt 203 connected in sequence at the other end. Since one end of two of the conveying rollers 201 is provided with a driving gear 306, and the driving gear 306 is meshed with the driven gear 305, the rotation of the conveying roller 201 will be driven by the driving gear 306. The wheel 306 and the driven gear 305 drive the electric heating roller 303 to rotate, so that the photovoltaic panel to be packaged placed on the conveying roller 201 will be conveyed into the packaging shell 3 through the feed port 301, and will be squeezed and packaged when passing through the electric heating roller 303; since the electric heating roller 303 is provided with an electric heating wire 501, before the photovoltaic panel to be packaged passes through the electric heating roller 303, the electric heating wire 501 is started by the controller 503 to heat the electric heating roller 303, so that when the photovoltaic panel to be packaged passes through the electric heating roller 303, the high temperature of the electric heating roller 303 can melt the adhesive film of the photovoltaic panel to be packaged, and the melted adhesive film can separate the photovoltaic cell sheet and the glass The panels are bonded to each other to achieve the packaging effect; secondly, the other end of the electric heating roller 303 is connected to a blower 401. Before the photovoltaic panel to be packaged enters the feed port 301, the blower 401 is started to allow external air to pass into the electric heating roller 303. The air is heated by the electric heating wire 501 inside the electric heating roller 303 and then ejected through the air jet hole 304. The ejected hot air flow will flow to the feed port 301 to preheat the photovoltaic panel to be packaged entering the feed port 301. At the same time, the high-speed air flow can also blow away the dust on the surface of the photovoltaic panel to be packaged, thereby cleaning the dust; finally, because the glass surface of the photovoltaic panel to be packaged is squeezed and packaged by the electric heating roller 303, the glass surface of the photovoltaic panel to be packaged is The board will produce a small amount of deformation. When the photovoltaic panel to be packaged leaves the extrusion packaging process, the glass panel and the photovoltaic cell will be separated due to the rebound of the glass panel. At this time, the adhesive film cannot fix the two after being softened by high temperature. Therefore, the separation between the glass panel and the photovoltaic cell will cause bubbles in the adhesive film, affecting the packaging effect. Therefore, when the photovoltaic panel to be packaged leaves the extrusion packaging process, the present invention continues to use the high-temperature gas sprayed by the electric heating roller 303 to blow the adhesive film to soften it. The softened adhesive film can fill the bubbles generated by the separation between the glass panel and the photovoltaic cell, so that the packaged photovoltaic panel will not generate bubbles, and the effect is better.

[0048] The present invention can preheat the photovoltaic panels to be packaged by blowing high-temperature air before extrusion packaging of the photovoltaic panels, and can also clear dust on their surfaces. Secondly, after the photovoltaic panels to be packaged leave the extrusion packaging process, they can continue to be blown with high-temperature air to avoid rapid cooling of the film to generate bubbles.

[0049] like Figure 4 , Figure 5 As shown, further, the air jet holes 304 are obliquely arranged on the surface of the electric heating roller 303, and the opening directions of the air jet holes 304 arranged on the surface of the two electric heating rollers 303 are respectively toward the feed port 301 and the discharge port 302;

[0050] Among them, by tilting the air jet holes 304 on the surface of the electric hot pressure roller 303 near the feed port 301 toward the feed port 301, and tilting the air jet holes 304 on the surface of the electric hot pressure roller 303 near the discharge port 302 toward the discharge port 302, the photovoltaic panels to be packaged can be blown by high-temperature air for preheating and dust removal when entering the feed port 301, and the packaged photovoltaic panels can also be blown by high-temperature air when being discharged from the discharge port 302, which can continue to soften the film and avoid the formation of bubbles inside the film.

[0051] like Figure 1 , Figure 3 As shown, further, a rotary joint 403 is provided at the connection between the air delivery pipe 402 and the electric heating pressure roller 303, and the electric heating pressure roller 303 can be rotatably connected to the air delivery pipe 402 through the rotary joint 403;

[0052] Among them, the rotating joint 403 is a dynamic sealing connector, which connects the air pipe 402 to the electric heating roller 303 through the rotating joint 403, which can ensure the connection between the air pipe 402 and the electric heating roller 303, and at the same time ensure that the air pipe 402 and the electric heating roller 303 can rotate relative to each other, so that when the electric heating roller 303 rotates, the air pipe 402 will not rotate with it, thereby avoiding the air pipe 402 hindering the rotation of the electric heating roller 303.

[0053] like Figure 1 , Figure 2 As shown, further, an electric slip ring 504 is provided at the connection between the electric heater connecting line 502 and the electric heating pressure roller 303, and the electric heating pressure roller 303 can be rotatably connected to the electric heater connecting line 502 through the electric slip ring 504;

[0054] Among them, the electric slip ring 504 is an electrical component that can rotate the two end wires while ensuring electrical connection. The electric heater connecting wire 502 is electrically connected to the electric heating wire 501 inside the electric heating roller 303 by using the electric slip ring 504, so that when the electric heating wire 501 rotates with the electric heating roller 303, the electric heater connecting wire 502 will not rotate with it, thereby preventing the electric heater connecting wire 502 from hindering the electric heating wire 501 from rotating with the electric heating roller 303.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, further, the driving motor 202 and the blower 401 are both electrically connected to the controller 503, and the controller 503 can be used to control the power-on status of the driving motor 202 and the blower 401 respectively.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, further, a dust removal reflux chamber 602 is provided above the feed port 301, a softening reflux chamber 603 is provided above the discharge port 302, the dust removal reflux chamber 602 is through-connected with the top of the softening reflux chamber 603, an air pump 601 is installed above the packaging shell 3, the connection between the dust removal reflux chamber 602 and the softening reflux chamber 603 is through-connected with the gas input end of the air pump 601, the gas output end of the air pump 601 is through-connected with the center of the top of the packaging shell 3, and the air pump 601 is used to pump the gas inside the dust removal reflux chamber 602 and the top end of the softening reflux chamber 603 to the inside of the packaging shell 3;

[0057] Among them, by arranging the dust removal reflux chamber 602 and the softening reflux chamber 603 above the feed port 301 and the discharge port 302, a part of the high-temperature air discharged from the electric hot pressing roller 303 will flow back to the top through the dust removal reflux chamber 602 and the softening reflux chamber 603 when passing through the feed port 301 and the discharge port 302, and then be pumped into the interior of the packaging shell 3 through the air pump 601, so that the high-temperature air can be recovered and the photovoltaic panel can be heated again, so as to further promote the softening of the film and improve the softening efficiency of the film; at the same time, by introducing air inward from the middle of the packaging shell 3, the air inside the packaging shell 3 can be promoted to flow toward the feed port 301 and the discharge port 302.

[0058] like Figure 4 As shown, further, an electric heating element 604 is arranged at the center of the inner part of the packaging shell 3, and the electric heating element 604 is arranged corresponding to the gas output end of the air pump 601, and the electric heating element 604 is used to heat the air output by the air pump 601;

[0059] Since the temperature of the recovered hot air decreases during the flow process, when the recovered air is passed into the packaging shell 3, the electric heating element 604 is used to further heat the recovered air as needed.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, further, the mounting frame 1 is located at the upper part of both sides of the end where the feed port 301 is located, and the swing rod 701 is rotatably installed, and the connection between the swing rod 701 and the mounting frame 1 is installed with a torsion spring 703, and the torsion spring 703 is used to limit the position of the swing rod 701, and the swing rod 701 is away from the lower part of the end of the torsion spring 703 and the limit roller 702 is vertically rotatably installed;

[0061] Among them, since the various structural layers of the photovoltaic panels are easily misaligned when placed, the structural layers of the photovoltaic panels are limited by setting a limiting roller 702. After the stacked photovoltaic panels are placed on the conveying roller 201, the stacked photovoltaic panels will be transported to the inside of the feed port 301 by the conveying roller 201, and will pass through the limiting roller 702 during the transportation process. If the structural layers are not placed neatly, the limiting roller 702 will be squeezed inward by the torsion spring 703 between the rocker arm 701 and the mounting frame 1. The squeezing of the limiting roller 702 will make the unevenly placed structural layers regular.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, further, an extrusion shell 801 is fixedly arranged above the discharge port 302, and the extrusion shell 801 is arranged between the packaging shell 3 and the softening reflux chamber 603, and a rubber extrusion roller 804 is rotatably installed inside the extrusion shell 801;

[0063] The rubber extrusion roller 804 is made of soft rubber;

[0064] Since the glass panel will produce a small amount of deformation when being squeezed by the electric hot pressing roller 303, and the glass panel rebounds after leaving the electric hot pressing roller 303 to produce a cavity in the adhesive film, therefore, by providing a rubber squeezing roller 804, the photovoltaic panel with air generated in the adhesive film can be gently pressed by the soft rubber squeezing roller 804 when passing through the rubber squeezing roller 804, so as to discharge the bubbles in the adhesive film and squeeze the adhesive film evenly.

[0065] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, further, spring chambers 802 are opened in the side walls at both ends of the extrusion shell 801, and a return spring 805 is arranged inside the spring chamber 802. One end of the return spring 805 is fixedly connected to the rotating shaft inside the rubber extrusion roller 804, and an adjusting bolt 803 is installed on the top of the spring chamber 802. The adjusting bolt 803 is used to adjust the extension space of the return spring 805;

[0066] By arranging a return spring 805 above the rubber squeezing roller 804 and taking into account the softness of the rubber squeezing roller 804, the deformation of the glass panel caused by the squeezing of the rubber squeezing roller 804 can be avoided to the greatest extent, and bubbles can be avoided in the rubber film again; secondly, by adjusting the extension space of the return spring 805 through the adjusting bolt 803, the squeezing force of the rubber squeezing roller 804 on the glass panel can be adjusted, so that the user can adjust it according to needs.

[0067] In summary: when in use, the photovoltaic cell sheets, adhesive films and glass panels are first stacked together in sequence, and then the stacked materials are placed together on the conveying roller 201 above the end where the feed port 301 is located. At this time, the drive motor 202 is started, and the drive motor 202 is used to drive one of the conveying rollers 201 to rotate. The rotation of this conveying roller 201 will drive all the conveying rollers 201 to rotate synchronously through the transmission belt 203 connected in sequence at the other end. Since one end of two of the conveying rollers 201 is provided with a driving gear 306, and the driving gear 306 is meshed with the driven gear 305, the rotation of the conveying roller 201 will be The electric heating roller 303 is driven to rotate by the driving gear 306 and the driven gear 305, so that the photovoltaic panel to be packaged placed on the conveying roller 201 will be conveyed into the packaging shell 3 through the feed port 301, and will be squeezed and packaged when passing through the electric heating roller 303; since the electric heating roller 303 is provided with an electric heating wire 501, before the photovoltaic panel to be packaged passes through the electric heating roller 303, the electric heating wire 501 is started by the controller 503 to heat the electric heating roller 303, so that when the photovoltaic panel to be packaged passes through the electric heating roller 303, the high temperature of the electric heating roller 303 can melt the adhesive film of the photovoltaic panel to be packaged, and the adhesive film can be melted to form the photovoltaic cell sheet. The hot air is then blown away by the hot air blower 401, and the hot air is then blown away by the hot air blower 401. The hot air is then blown away by the hot air blower 401, and the hot air is then blown away by the hot air blower 401. The hot air is then blown away by the hot air blower 401, and the hot air is then blown away by the hot air blower 401. The glass panel will produce a small amount of deformation. When the photovoltaic panel to be packaged leaves the extrusion packaging process, the glass panel and the photovoltaic cell will be separated due to the rebound of the glass panel. At this time, the adhesive film cannot fix the two after being softened by high temperature. Therefore, the separation between the glass panel and the photovoltaic cell will cause bubbles in the adhesive film, affecting the packaging effect. Therefore, when the photovoltaic panel to be packaged leaves the extrusion packaging process, the present invention continues to use the high-temperature gas sprayed by the electric heating roller 303 to blow the adhesive film to soften it. The softened adhesive film can fill the bubbles generated by the separation between the glass panel and the photovoltaic cell, so that the packaged photovoltaic panel will not generate bubbles, and the effect is better.
