Description

Technical Field

[0001] This invention relates to the field of edge banding equipment, and more specifically, to an automatic edge banding device for double-glass modules. Background Technology

[0002] Compared to conventional monocrystalline cells, bifacial photovoltaic modules can generate electricity under both direct sunlight on the front and reflected sunlight received on the back. Because they can generate electricity from both sides, double-glass modules have wide applications in the solar power industry. A double-glass module consists of two layers of glass and solar cells located in the middle. During processing, these are sealed together using edge-sealing equipment to form a single unit. However, existing edge-sealing equipment still has certain problems. The solar cells located between the two layers of glass sometimes need to maintain a certain position and orientation before edge-sealing, and existing edge-sealing equipment cannot automatically adjust the position and orientation of the solar cells between the two layers of glass before edge-sealing. Therefore, this paper presents an automatic edge-sealing device for double-glass modules that can adjust the orientation of the solar cells. Summary of the Invention

[0003] This invention provides an automatic edge-sealing device for double-glass modules, which solves the technical problem in related technologies that cannot automatically adjust the position and orientation of solar cells located between double-glass layers before edge sealing.

[0004] According to one aspect of the present invention, an automatic edge-sealing device for double-glass modules is provided, comprising a conveying mechanism, the conveying mechanism including a conveying platform and a plurality of side rollers, the side rollers being evenly distributed on both sides of the conveying platform and the axis of the side rollers being perpendicular to the conveying platform, the side rollers being driven by a power component; a correction component is also provided, the correction component including connecting frames respectively disposed on both sides of the material advance channel above the conveying platform, a plurality of correction rods being fixedly disposed on one side of the connecting frame near the material advance channel, the thickness of the correction rods corresponding to the thickness of the solar cell located between the double-glass modules, and the contour formed by the connection of the ends of the correction rods away from the connecting frame corresponding to the contour of the target position of the solar cell, the other end of the connecting frame being provided with a telescopic drive component for driving the connecting frame toward or away from the material advance channel, a positioning plate corresponding to the position of the connecting frame being disposed on the material advance channel of the conveying platform, and a drive rod for driving the positioning plate to move up and down being disposed below the positioning plate.

[0005] The above technical solution involves a correction component. The contour formed by the correction rod at the end away from the connecting frame corresponds to the contour of the target position of the solar cell. Therefore, after the correction rod reaches its final position, the solar cell is positioned at the target position and maintains the target posture under the constraint of the correction rod. This achieves high-precision automatic adjustment of the position and posture of the solar cell located between the double-layer glass before edge sealing, so as to facilitate subsequent edge sealing processing. Furthermore, with the telescopic drive components on both sides traveling at the same distance, the position of the solar cell relative to the double-layer glass and the edge distance of the solar cell relative to the edge of the double-layer glass can be guaranteed.

[0006] Preferably, a contact block with a shape corresponding to the edge contour of the solar cell is fixedly provided at the end of the straightening rod away from the connecting frame, and the width of the contact block is greater than the width of the straightening rod, and the side of the contact block close to the solar cell is smoothly disposed.

[0007] The above technical solution enhances the accuracy of solar cell position determination during attitude correction by increasing the contact area with the edge of the solar cell through the setting of a wider contact block.

[0008] Preferably, a plurality of sliding rods and an inclined limiting rod are also provided. The sliding rods slide through the connecting frame and are located outside the correcting rod. One end of the sliding rod is connected to the limiting rod, and a tension spring is provided between the other end and the connecting frame.

[0009] The above technical solution involves setting an inclined limiting rod that guides the solar cell during its forward movement, providing a coarse adjustment of its position. This confines the solar cell within the area effectively influenced by the correction rod, ensuring the effectiveness of the correction component.

[0010] Preferably, a centering rod is also provided, and the centering rod is an automatic telescopic rod. One end of the centering rod is rotatably connected to the side of the sliding rod, and the other end is rotatably connected to the limiting rod. The limiting rod and the sliding rod are rotatably connected.

[0011] The above technical solution allows the adjusting rod to be extended or shortened, which can drive the limiting rod to swing, further expanding the range of influence of the limiting rod and improving the ability to adjust the position of the solar cells.

[0012] Preferably, a pressure component is also provided above the conveying platform. The pressure component includes a support frame and several pressure rollers rotatably mounted on the support frame. The linear velocity of the pressure rollers at the point where they contact the solar cells is the same as the linear velocity of the side rollers at the point where they contact the solar cells. A lifting drive is provided above the support frame to drive the support frame to move up and down.

[0013] The above technical solution applies pressure to the double-glass module material to be sealed by pressure rollers, preventing the corrected solar cells from shifting position again during transportation. At the same time, since the side rollers and pressure rollers rotate at the same speed, the problem of misalignment of the double-layer glass that may be caused by speed difference is avoided.

[0014] Preferably, the correcting rod is provided with a buffer structure. The correcting rod includes an outer rod and an inner support rod. One end of the inner support rod is slidably disposed in the cavity of the outer rod through a limiting block. The connecting frame has a pressure chamber that communicates with the cavities of several outer rods. The pressure chamber is provided with a pressure medium. In the free state, the contour formed by the connection of the ends of several inner support rods away from the connecting frame corresponds to the contour of the target position of the solar cell.

[0015] The above technical solution can prevent excessive pressure from the rigid straightening rod on the solar cell during the process of straightening the solar cell's posture, which could lead to the solar cell being squeezed and damaged.

[0016] Preferably, the connecting frame has an adjustment hole that connects the pressure chamber to the outside, and a piston is installed in the adjustment hole for sealing.

[0017] The above technical solution enables the adjustment of the pressure inside the pressure chamber as needed.

[0018] Preferably, the straightening rod is provided with a buffer structure. The straightening rod includes an outer rod and an inner support rod. One end of the inner support rod is slidably set in the cavity of the outer rod through a limiting block. Compression springs with the same elastic coefficient are respectively set in the cavity of the outer rod. In the free state, the contour formed by connecting the ends of several inner support rods away from the connecting frame corresponds to the contour of the target position of the solar cell.

[0019] The above technical solution can prevent excessive pressure from the rigid straightening rod on the solar cell during the process of straightening the solar cell's posture, which could lead to the solar cell being squeezed and damaged.

[0020] Preferably, the end of the telescopic drive assembly furthest from the connecting frame is fixedly mounted on the mounting frame, which is mounted on a fixed base frame.

[0021] The above technical solution allows for the adjustment of the relative center positions of two telescopic drive components by using a mounting bracket with mounting settings. When the extension of the two telescopic drive components is the same, the position of the solar cell between them can be adjusted, ultimately changing the spacing between the two sides of the solar cell and the outer glass.

[0022] Preferably, the power assembly includes a transmission belt and transmission wheels. The transmission wheels are located at the end of the side roller away from the conveying platform, and the transmission belt drives and connects several transmission wheels and the output end of the motor.

[0023] The beneficial effects of this invention are as follows: A correction component is provided, which enables automatic adjustment of the posture of the solar cells in the double-glass module material to be edge-sealed, with high adjustment accuracy, facilitating subsequent edge-sealing processing. When the travel distances of the telescopic drive components on both sides are consistent, the position of the solar cells relative to the double-layer glass, as well as the edge distance of the solar cells relative to the edges of the double-layer glass, can be guaranteed. Simultaneously, a buffer structure is provided on the correction rod to prevent excessive pressure applied to the solar cells by the rigid correction rod during the correction process, which could lead to damage to the solar cells. Furthermore, a pressure component is provided to apply pressure to the corrected double-glass module material, preventing further positional changes during subsequent transport. A mounting bracket is provided to adjust the relative center positions of the two telescopic drive components, thereby adjusting the final, defined position of the solar cells.

[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein, and are not intended to limit the scope, applicability, or examples set forth in the claims. The function and arrangement of the elements discussed may be changed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the various examples. Furthermore, features described in some examples may be combined in other examples.

[0035] Example

[0036] like Figures 1-3As shown, an automatic edge-sealing device for double-glass modules includes a conveying mechanism, which includes a conveying platform 6 and several side rollers 2. The side rollers 2 are evenly distributed on both sides of the conveying platform 6, and the axis of the side rollers 2 is perpendicular to the conveying platform 6. The material advance channel of the double-glass module material to be edge-sealed is between the side rollers 2 on both sides. The conveying mechanism is used to convey the double-glass module material to be edge-sealed. In use, the double-glass module material to be edge-sealed is located in the material advance channel area, that is, the position between the side rollers 2 above the conveying platform 6. The side rollers 2 drive the double-glass module material to be edge-sealed forward. At the same time, the side rollers 2 play a role in limiting the side force on the double-glass module material to be edge-sealed. Therefore, it is preferable that the side of the side rollers 2 is roughened to increase the friction resistance. The side rollers 2 are driven by a power component.Solar cells located between double-glazed windows sometimes need to maintain a certain position and orientation between the two panes. While existing edge-sealing processes set the position of the solar cells relative to the double-glazed windows when assembling the double-glazed modules, this setting is relatively coarse and cannot guarantee precision. Furthermore, the position of the solar cells may shift during the movement of the double-glazed module material. Therefore, to automatically adjust the position and orientation of the solar cells between the double-glazed windows before edge sealing, a correction component is also included. This correction component comprises components positioned on both sides of the material advance channel above the conveyor platform 6. A connecting frame 3 has several straightening rods 4 fixedly installed on one side near the material infeed channel. The thickness of the straightening rods 4 corresponds to the thickness of the solar cell located between the double-layer glass. The contour formed by connecting the ends of the straightening rods 4 away from the connecting frame 3 corresponds to the contour of the target position of the solar cell. That is, the contour line formed by connecting the ends of the straightening rods 4 away from the connecting frame 3 corresponds to the edge contour line of the solar cell when its posture needs to be maintained. If the solar cell is elliptical (irregularly shaped) and its position needs to be tilted, then the contour line formed by connecting the ends of the straightening rods 4 away from the connecting frame 3 is a corresponding tilted arc. The other end of the connecting frame 3 is... A telescopic drive assembly 1, with a drive connecting frame 3 facing or away from the material advance channel, is provided. The selection of the telescopic drive assembly 1 is unrestricted; pneumatic or hydraulic telescopic rod structures can be used. Preferably, the telescopic drive assemblies 1 on both sides are of the same specification, meaning the travel distance on both sides can be consistent. To ensure that the double-glass component material to be sealed can travel to a designated position and stop, and then the correction assembly functions, a positioning plate 11 corresponding to the position of the connecting frame 3 is also provided on the material advance channel of the conveying platform 6. A drive rod is provided below the positioning plate 11 to drive its up and down movement. That is, during the process of the conveying mechanism transporting the double-glass component material to be sealed, the positioning plate 11... The obstruction prevents the double-glass module material to be sealed from advancing at the location of the connecting frame 3, thus ensuring that the positions of the straightening component and the double-glass module material to be sealed correspond. During use, the positioning plate 11 is moved upwards by the drive rod and extends above the conveying platform 6, serving a positioning function as the double-glass module material moves forward. When the material is blocked by the positioning plate 11, the conveying mechanism stops working, and the material is positioned corresponding to the straightening component. The straightening component then straightens the solar cells. After straightening, the drive rod drives the positioning plate 11 downwards, and the conveying mechanism transports the straightened double-glass module material.

[0037] As one embodiment of the present invention, such as Figure 1As shown, a contact block 5 with a shape corresponding to the edge contour of the solar cell is fixedly installed at the end of the correction rod 4 away from the connecting frame 3. The width of the contact block 5 is greater than the width of the correction rod 4. The side of the contact block 5 close to the solar cell is smoothly arranged. By setting a contact block 5 with a larger width, the contact area with the edge of the solar cell is increased, thereby enhancing the accuracy of the position limit of the solar cell during the attitude correction process.

[0038] As one embodiment of the present invention, such as Figures 1-2 As shown, the solar cells located between the double-layered glass may sometimes be offset by a considerable distance, making it impossible for them to be within the effective influence area of ​​the corrective rod 4. Therefore, several sliding rods 21 and inclined limiting rods 20 are also provided. The sliding rods 21 slide through the connecting frame 3 and are located outside the corrective rod 4. One end of the sliding rod 21 is connected to the limiting rod 20, and a tension spring 22 is provided between the other end and the connecting frame 3. That is, the limiting rod 20 and the tension spring 22 are located on both sides of the connecting frame 3. The area enclosed by the limiting rod 20 is larger than the area formed by the end of the corrective rod 4. When the connecting frame 3 faces the edge to be sealed... During the movement of the double-glass module material, the limiting rod 20 contacts the material first. If the solar cell located between the double glass layers is offset by a large distance and cannot be located within the area that the correcting rod 4 can effectively influence, the inclined limiting rod 20 can guide the solar cell to move in a certain way during the forward movement, limiting the solar cell within the area that the correcting rod 4 can effectively influence. The sliding rod 21 is slidably set and is equipped with a tension spring 22 to provide elasticity. When the limiting rods 20 on both sides are connected, the sliding rod 21 will slide to ensure the continued movement of the connecting frame 3, and then the correcting module will play its role.

[0039] As one embodiment of the present invention, such as Figure 4 As shown, to further enhance the ability of the limiting rod 20 to adjust the position of the solar cell, a centering rod 12 is also provided. The centering rod 12 is an automatically telescopic rod. One end of the centering rod 12 is rotatably connected to the side of the sliding rod 21, and the other end is rotatably connected to the limiting rod 20. Correspondingly, the limiting rod 20 and the sliding rod 21 are rotatably connected. The specific structure of the centering rod 12 is not limited; a hydraulic or pneumatic automatically telescopic rod can be used. By extending or shortening the centering rod 12, the limiting rod 20 can be driven to swing, thereby adjusting the position of the solar cell. Figure 4 As shown in the attached figure, when the adjusting rod 12 is shortened, the range that the outer end of the limiting rod 20 can influence is larger.

[0040] As one embodiment of the present invention, such as Figure 3As shown, to prevent the position of the solar cells from changing again during the next process (filling and sealing after posture correction), a pressure component is also provided above the conveying platform 6. The pressure component includes a support frame 10 and several pressure rollers 9 rotatably mounted on the support frame 10. Preferably, the linear velocity of the pressure roller 9 at the point of contact with the solar cells is the same as the linear velocity of the side roller 2 at the point of contact with the solar cells. A lifting drive is provided above the support frame 10 to drive the support frame 10 to move up and down. In use, after the position of the solar cells is corrected by the above-mentioned correction component, the support frame 10 is moved down by the lifting drive until the side of the pressure roller 9 contacts the upper surface of the double-glass module material to be sealed, applying pressure to the double-glass module material to be sealed. Then, the conveying mechanism is started to convey the double-glass module material to be sealed. The pressure roller 9 applies pressure to the double-glass module material to be sealed to prevent the corrected solar cells from changing position again during the conveying process. At the same time, since the rotation speeds of the side roller 2 and the pressure roller 9 are the same, the problem of misalignment of the double-layer glass that may be caused by speed difference is avoided.

[0041] As one embodiment of the present invention, such as Figure 5 and Figure 6 As shown, to prevent excessive pressure applied to the solar cell by the rigid straightening rod 4 during the process of straightening the solar cell's attitude, which could lead to damage to the solar cell, a buffer structure is provided on the straightening rod 4. The straightening rod 4 includes an outer rod 15 and an inner support rod 16. One end of the inner support rod 16 is slidably disposed in the cavity of the outer rod 15 through a limiting block 17. A pressure chamber 14 is provided in the connecting frame 3, which communicates with the cavities of several outer rods 15, and a pressure medium is provided in the pressure chamber 14. In the free state, the contour formed by the connection of the ends of several inner support rods 16 away from the connecting frame 3 corresponds to the contour of the target position of the solar cell, that is, the inner support rod 16 is under pressure. When in an elongated state under the action, the contour formed by its farthest connection corresponds to the contour of the target position of the solar cell. The pressure medium is not limited and can be gas or liquid to form a pneumatic or hydraulic structure. As an embodiment of the present invention, the connecting frame 3 is provided with an adjustment hole that connects the pressure chamber 14 to the outside. A piston is set in the adjustment hole for sealing. The buffer structure plays a buffering role in the process of correcting the posture of the solar cell by the forward movement of the correcting rod 4, preventing the solar cell from being squeezed and damaged. Moreover, the cavities in several outer rods 15 are connected and have the same pressure, ensuring that the different inner support rods 16 are subjected to balanced force and the accuracy of the solar cell posture adjustment.

[0042] As one embodiment of the present invention, such as Figure 5 , Figure 7As shown, to prevent excessive pressure from the rigid straightening rod 4 on the solar cell during the forward correction of the solar cell's attitude, which could lead to damage to the solar cell, a buffer structure is provided on the straightening rod 4. The straightening rod 4 includes an outer rod 15 and an inner support rod 16. One end of the inner support rod 16 is slidably disposed in the cavity of the outer rod 15 through a limiting block 17. Based on Embodiment 1, but different from Embodiment 1, compression springs 18 with the same elastic coefficient are respectively provided in the cavity of the outer rod 15. In the free state, the contour formed by connecting the ends of several inner support rods 16 away from the connecting frame 3 corresponds to the contour of the target position of the solar cell. That is, when the inner support rod 16 is in an extended state under the action of elastic force, the contour formed by connecting its farthest end corresponds to the contour of the target position of the solar cell. By providing compression springs 18 as a buffer structure, a buffering effect is played during the forward correction of the solar cell's attitude by the straightening rod 4, preventing the solar cell from being damaged by compression.

[0043] As one embodiment of the present invention, such as Figures 8-9 As shown, the end of the telescopic drive assembly 1 furthest from the connecting frame 3 is fixedly mounted on the mounting frame 19, and the mounting frame 19 is mounted on the fixed base frame 13, as shown in the attached figure. Figure 9 As shown, the mounting bracket 19 and the fixed base 13 are connected by bolts. The fixed base 13 has a slot. The other end of the bolt can change its position in the slot, thereby changing the position of the mounting bracket 19 on the fixed base 13. The mounting bracket 19 with the mounting settings can adjust the relative center position of the two telescopic drive components 1. When the extension of the two telescopic drive components 1 is the same, the position of the solar cell between them can be adjusted, and the spacing between the two sides of the solar cell and the outer glass can be changed. The telescopic drive components 1 can also be replaced by screw components. The screw components drive the connecting bracket 3 to move towards or away from each other, which can ensure better alignment and synchronization.

[0044] As one embodiment of the present invention, the selection of the power component is not limited. For example, such as Figure 3 As shown, the power assembly includes a transmission belt 7 and transmission wheels 8. The transmission wheels 8 are located at the end of the side roller 2 away from the conveying platform 6. The transmission belt 7 drives and connects several transmission wheels 8 and the output end of the motor. The driving effect is achieved by driving and connecting the motor and several transmission wheels 8 through the transmission belt 7. The belt drive can also be replaced by chain drive. The driving of several pressure rollers 9 is the same.

[0045] Working Principle: In operation, this device drives several side rollers 2 to rotate via a power component. The double-glass module material to be sealed (double-layered glass and solar cells between the double-layered glass) is positioned above the conveying platform 6 between the side rollers 2. The side rollers 2 propel the material forward, simultaneously applying lateral force to limit its movement. When the material reaches the positioning plate 11, it stops under the action of the positioning plate 11. At this point, the material is positioned at the connecting frame 3, and the conveying mechanism stops, meaning the side rollers 2 stop rotating. Then... The telescopic drive assembly 1 drives the connecting frames 3 on both sides to move simultaneously toward the double-glass module material to be sealed, located on the material advance channel. The ends of the straightening rod 4 and the limiting rod 20 away from the connecting frame 3 extend into the space between the double-layer glass. If the solar cell between the double-layer glass is offset by a large distance and cannot be located within the area effectively affected by the straightening rod 4, then during the movement, the limiting rod 20 with a larger coverage area can contact the material first. The inclined limiting rod 20 can guide the movement of the solar cell during the advance, confining the solar cell within the area effectively affected by the straightening rod 4, until the limiting rods on both sides... After docking, the sliding rod 21 compensates for the subsequent stroke of the connecting frame 3. Then, as the connecting frame 3 continues to move, the end of the correcting rod 4 away from the connecting frame 3 moves and touches the solar cell. Since the contour formed by the connection of several ends of the correcting rods 4 away from the connecting frame 3 corresponds to the contour of the target position of the solar cell, when the elliptical solar cell is not in the target position and attitude, the solar cell and the correcting rod 4 are in an unstable point contact state. Under the squeezing action, the solar cell will shift towards the target attitude until the solar cell is in the target position and attitude. The straightening rods 4 form a stable line contact with the outer contour of the entire structure. Thus, the position and orientation of the solar cell are corrected by the straightening rods 4 during their movement. Under the constraint of the straightening rods 4, the solar cell is in the target position and maintains the target orientation for processing. After the adjustment is completed, the pressure component applies pressure to the double-glass module material to be sealed to prevent the position from changing. The telescopic drive component 1 drives the connecting frames 3 on both sides to move away from the adjusted double-glass module material to be sealed. The drive rod drives the positioning plate 11 to descend and open the conveying channel. Then, the conveying mechanism transports the double-glass module material to be sealed toward the next process (sealing).

[0046] In summary, by providing a correction component, the position and orientation of the solar cell between the double-layer glass can be corrected and adjusted with high precision. When the travel distance of the telescopic drive components 1 on both sides is consistent, the position of the solar cell relative to the double-layer glass and the edge distance of the solar cell relative to the edge of the double-layer glass can be guaranteed. Furthermore, the mounting bracket 19 with the mounting device can adjust the relative center position of the two telescopic drive components 1, thereby adjusting the final fixed position of the solar cell.

[0047] The embodiments of this embodiment have been described above with reference to the accompanying drawings.
