Description

Technical Field

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

[0002] With the deepening of industrial development in recent years, human development has become increasingly dependent on energy. However, due to the non-renewable nature of fossil energy and the environmental problems associated with greenhouse gas emissions, society has turned its attention to efficient, long-lasting, and pollution-free solar energy. The development and utilization of solar energy will play a crucial role in the structural adjustment of future energy development. Furthermore, driven by the trend towards carbon neutrality, the photovoltaic industry is expected to lead the rapid development of renewable energy.

[0003] As the photovoltaic industry continues to grow and improve, efficient and low-cost manufacturing methods have become an effective means for companies to enhance their competitiveness. In the double-glass photovoltaic module manufacturing process, the lamination process is an integral part of the entire module production process. The lamination process involves placing the laid double-glass photovoltaic modules into a laminator, extracting the air from the module through vacuum, then heating the film to melt it and applying pressure to force it to flow and fill the gaps between the glass, cells, and backsheet. Simultaneously, air bubbles are expelled through compression, tightly bonding the cells, glass, and backsheet together. Finally, the process cools and solidifies, tightly bonding the cell glass and backsheet together into a single unit.

[0004] At the same time, with the increasing competition in the market, in order to meet different market demands, modules with different backsheet types such as single-glass modules and double-glass modules have been developed, enriching the diversification of the double-glass photovoltaic module market. Unlike single-glass modules, double-glass modules are subjected to greater pressure during the lamination process due to the glass on the back, which causes the adhesive film at the edge of the module to become thinner, ultimately reducing the reliability of the double-glass modules. In order to improve the reliability of double-glass photovoltaic modules to the same level as single-glass modules during the lamination process, it is necessary to manually place lightweight aluminum frames (lamination tooling or lamination frames) on the edges of the double-glass photovoltaic modules during the lamination process. Manual frame placement not only affects the efficiency of the entire lamination process, but also increases the labor cost in the manufacturing process of double-glass photovoltaic modules. At the same time, the production statistics of the double-glass photovoltaic module industry show that the manual placement of lamination tooling will also result in a 0.01% failure rate.

[0005] In order to solve the problem of manual frame placement, some companies have added silicone strips to the high-temperature cloth of the laminator to replace manual frame placement. This method can also solve the disadvantages brought by manual frame placement, but because the silicone strips are fixed on the high-temperature cloth and cannot be moved, when changing the production of components of different specifications and sizes, different types of high-temperature cloth need to be replaced, so this method is not universal.

[0006] For example, the prior art patent publication number 202223513608.3 discloses a double-glass photovoltaic module built-in tooling lamination system, which includes a laminator cover, and a number of laminating tools are fixedly connected on both sides of the lower cover of the laminator by screws on the connecting plate. The lower side of the laminating tooling is connected to the first high-temperature cloth, and the first high-temperature cloth is connected to the second high-temperature cloth through the double-glass module, and the second high-temperature cloth is arranged on the bottom plate of the laminator. During processing, the double-glass modules to be laminated are placed in batches between the first high-temperature cloth and the second high-temperature cloth, and are located on the lower side of adjacent laminating tools. During lamination, the four laminating tools can support the four corners of the double-glass module. However, this prior art also requires the replacement of different types of high-temperature cloth when replacing double-glass photovoltaic modules of different specifications and sizes.

[0007] It can be seen that the current method of manually placing the laminate frame is time-consuming, has poor stability and high manufacturing cost. Utility Model Content

[0053] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0054] In order to solve the problems of the prior art in which manual placement of laminating frames is time-consuming, unstable, and has high manufacturing costs, the present invention provides a laminating machine. Figure 1 The laminator includes a laminator body 10 and a pick-and-place mechanism. The laminator body 10 includes a feed table 11, a laminating mechanism 12 and a discharge table 13, and the laminating mechanism 12 is located between the feed table 11 and the discharge table 13. The pick-and-place mechanism includes a mounting frame 20, a grabbing assembly 30 and a control device. The grabbing assembly 30 includes a plurality of grabbing assemblies 30, and the plurality of grabbing assemblies 30 are installed above the laminator body 10 through the mounting frame 20, with low assembly difficulty and high efficiency. At least one grabbing assembly 30 is located above the feed table 11, and at least one grabbing assembly 30 is located above the discharge table 13. The control device is connected to the grabbing assembly 30 to at least control the grabbing assembly 30 to grab or release the laminating frame. The specific structure of the mounting frame 20 can be determined according to the installation position of the grabbing assembly 30 and the structure of the laminator body 10.

[0055] Conveyor belts are provided between the feed table 11 and the laminating mechanism 12, and between the laminating mechanism 12 and the discharge table 13. Before the double-glass photovoltaic module enters the laminating mechanism 12 for lamination, it can first be conveyed to the feed table 11 by the conveyor belt of the previous production line, and then the gripped lamination frame is placed on the double-glass photovoltaic module by the grabbing assembly 30. The double-glass photovoltaic module with the lamination frame is then conveyed to the laminating mechanism 12 by the conveyor belt for lamination by the laminating mechanism 12. The laminated double-glass photovoltaic module is conveyed to the discharge table 13 by the conveyor belt. At this time, the gripping assembly 30 on the discharge table 13 is controlled by the control device to grab the lamination frame from the double-glass photovoltaic module. The operation is efficient and convenient, and the explosion rate caused by manual frame placement can be reduced, thereby improving the production efficiency and product quality of the double-glass photovoltaic module and reducing production costs.

[0056] Therefore, through the above technical solution, the laminator provided in this embodiment includes a pick-and-place mechanism, wherein a plurality of gripping assemblies 30 of the pick-and-place mechanism are mounted above the laminator body 10 via a mounting frame 20, and at least one gripping assembly 30 is located above the feed table 11 of the laminator body 10, and at least one gripping assembly 30 is located above the discharge table 13 of the laminator body 10. The control device of the pick-and-place mechanism is connected to the gripping assembly 30 to control the gripping assembly 30 to grip or release the laminating frame. Thus, when the double-glass photovoltaic module is transferred to the feed table 11, the gripping assembly 30 can be controlled by the control device to place the gripped laminating frame on the edge of the double-glass photovoltaic module. Then, when the double-glass photovoltaic module enters the laminating mechanism 12 for lamination, the edge of the double-glass photovoltaic module is protected by the laminating frame. When the laminated double-glass photovoltaic module is transferred to the discharge platform 13, the control device controls the grabbing assembly 30 to grab the lamination frame on the double-glass photovoltaic module and separate it from the double-glass photovoltaic module, thereby improving the placement efficiency of the lamination frame, improving the stability of the frame process, reducing labor costs, and thus reducing the manufacturing cost of the double-glass photovoltaic module.

[0057] In some embodiments, the gripping assembly 30 includes a conveyor 31 and a clamp 32. The conveyor 31 is mounted on the mounting frame 20. The clamp 32 is connected to the conveyor 31. Along a first direction, the clamp 32 has a first position close to the laminator body 10 and a second position away from the laminator body 10. When the clamp 32 is in the first position, the lamination frame can be placed on the double-glass photovoltaic module on the feed table 11. When the clamp 32 is in the second position, the lamination frame on the double-glass photovoltaic module on the discharge table 13 can be grasped until the conveyor 31 drives the lamination frame to descend and separate from the double-glass photovoltaic module.

[0058] The control device is connected to the conveyor 31 and the clamp 32 respectively. The control device controls the conveyor 31 to drive the clamp 32 to move back and forth between the first position and the second position, and controls the clamp 32 to grab or release the lamination frame. Thus, when the double-glass photovoltaic module is conveyed to the feed table 11, the control device controls the clamp 32 located on the feed table 11 to grab the lamination frame, and controls the conveyor 31 to move the clamp 32 holding the lamination frame to the first position (the first position can be a position where the lamination frame is 0.5 cm to 1 cm away from the feed table 11). Then, the control device controls the clamp 32 to release the lamination frame so that the lamination frame falls on the edge of the double-glass photovoltaic module. After the lamination frame is placed, the control device controls the conveyor 31 to pull the clamp 32 up to the second position. The lamination frame enters the lamination mechanism 12 along with the double-glass photovoltaic module for the normal lamination process. After the laminated double-glass photovoltaic module is transferred to the discharge platform 13, the control device controls the conveyor 31 to move the clamping jaws 32 to the first position near the discharge platform 13. The clamping jaws 32 then grasp the lamination frame. The conveyor 31 then controls the clamping jaws 32 to the second position, separating the lamination frame from the double-glass photovoltaic module. The conveyor 31 and clamping jaws 32 are easy to assemble and control.

[0059] Along the width direction of the laminator body 10, multiple grabbing components 30 can be set on the feed table 11 and the discharge table 13, so that the lamination frame can be placed on the edge of the double-glass photovoltaic module on the feed table 11 at the same time through the multiple grabbing components 30, and the lamination frame on the discharge table 13 can be grabbed and separated from the double-glass photovoltaic module at the same time through the multiple grabbing components 30.

[0060] In some embodiments, the mounting frame 20 may further include a transfer track 50, each extending in a first direction. The transfer track 50 may include two transfer tracks 50, one located above the feed station 11 and the other located above the discharge station 13. The conveyor 31 is connected to the transfer track 50 and is movable relative to the transfer track 50 in the first direction. This facilitates the control device to control the gripper 32 to accurately place the lamination frame on the double-glass photovoltaic module when the transfer track 50 on the feed station 11 and the discharge station 13 is moved relative to the transfer track 50. Alternatively, the gripper 32 can grasp the lamination frame and separate it from the double-glass photovoltaic module under the control of the transfer track 31. The transfer track 31 may be connected to the transfer track 50 via rollers. A drive motor is mounted on the transfer track 31 to drive the rollers. The drive motor is electrically connected to the control device, enabling the control device to activate the drive motor. Upon activation, the drive motor drives the rollers to roll relative to the transfer track 50, thereby transporting the transfer track 31 to the location of the double-glass photovoltaic module.

[0061] In some embodiments, the transmission member 31 may be a motorized telescopic rod, and the clamping claw 32 is connected to the telescopic end of the motorized telescopic rod so that the clamping claw 32 can reciprocate between the first position and the second position under the telescopic movement of the motorized telescopic rod.

[0062] In some embodiments, the conveyor 31 may include a retractable robotic arm, and the gripper 32 is connected to the movable end of the retractable robotic arm so as to move closer to or away from the double-glass photovoltaic module under the drive of the retractable robotic arm.

[0063] In some embodiments, the conveyor 31 of one or more gripping assemblies 30 may be a motorized telescopic rod, or a telescopic robotic arm. Regardless of the structure of the conveyor 31, as long as it can drive the gripper 32 to the desired position, it will suffice. Both telescopic robotic arms and motorized telescopic rods are readily available commercially, reducing the development cost of the pick-and-place mechanism and facilitating installation.

[0064] See Figure 2 In some embodiments, the clamping jaw 32 includes a compression cylinder 321, a telescopic link assembly 323, and a clamping assembly 322. The compression cylinder 321 includes a piston rod 211 and is electrically connected to a control device so that the control device can control the activation of the compression cylinder 321. Driven by the compression cylinder 321, the piston rod 211 can reciprocate along its axis. The clamping assembly 322 includes a first clamping portion 221 and a second clamping portion 222. The first and second clamping portions 221, 222 are rotatably mounted on the compression cylinder 321 and are located on opposite sides of the piston rod 211 along its radial direction. The telescopic link assembly 323 is connected between the piston rod 211 and the first and second clamping portions 221, 222. The piston rod 211 drives the telescopic link assembly 323 to move the first and second clamping portions 221, 222 closer to or farther from each other. Thus, when the control device controls the clamping jaws 32 to clamp the lamination frame, the control device controls the piston rod 211 of the compression cylinder 321 to retract, so that the piston rod 211 drives the telescopic connecting rod component 323 to move the first clamping portion 221 and the second clamping portion 222 closer to each other to clamp the lamination frame. When the control device controls the clamping jaws 32 to lower the lamination frame, the control device controls the piston rod 211 of the compression cylinder 321 to extend, so that the piston rod 211 drives the telescopic connecting rod component 323 to move the first clamping portion 221 and the second clamping portion 222 away from each other, thereby releasing the lamination frame and placing the lamination frame on the double-glass photovoltaic module or returning it to the storage position. The clamping jaws 32 in this embodiment have a stable and reliable structure and are easy to assemble.

[0065] In some embodiments, the clamping jaws 32 may include at least two, such as the clamping jaws 32 may include two, three, four, five, etc. When the clamping jaws 32 include two, the two clamping jaws are connected to the conveying member 31 (such as being connected to the movable end of the telescopic robot arm) so that the conveying member 31 simultaneously drives the two clamping jaws 32 to the first position or the second position. The two clamping jaws 32 can respectively clamp the borders on the opposite sides of the laminate frame through their respective clamping parts 322, thereby improving the stability of the grabbing assembly 30 when grabbing the laminate frame. When the clamping jaws 32 include four, the four clamping jaws 32 can be connected to the conveying member 31 through the connecting block, and the four clamping jaws 32 respectively clamp the four borders of the laminate frame through their respective clamping parts 322, thereby making the grabbing assembly 30 stronger, more stable and reliable in grabbing the laminate frame.

[0066] In some embodiments, the telescopic link component 323 includes a first connecting rod 231, a second connecting rod 232, and a third connecting rod 233. The middle portion of the first connecting rod 231 is sleeved onto one end of the piston rod 211. The first connecting rod 231 includes a first end 311 and a second end 312 that are oppositely disposed. The first end 311 is located at the end of the first connecting rod 231 near the first clamping portion 221, and the second end 312 is located at the end of the first connecting rod 231 near the second clamping portion 222. The second connecting rod 232 is rotatably connected between the first end 311 and the first clamping portion 221. The third connecting rod 233 is rotatably connected between the second end 312 and the second clamping portion 222. Thus, when the piston rod 211 drives the first connecting rod 231 to retract along its own axial direction, the second connecting rod 232 and the third connecting rod 233, under the pulling action of the first connecting rod 231, pull the first clamping portion 221 and the second clamping portion 222 closer to each other, so that the first clamping portion 221 and the second clamping portion 222 can clamp the laminate frame. When the piston rod 211 drives the first connecting rod 231 to extend away from the main body of the compression cylinder 321 along its own axial direction, the second connecting rod 232 and the third connecting rod 233, under the pushing action of the first connecting rod 231, push the first clamping portion 221 and the second clamping portion 222 away from each other, thereby releasing the clamped laminate frame. When the telescopic link component 323 in this embodiment is assembled by the first connecting rod 231, the second connecting rod 232 and the third connecting rod 233, not only is it convenient and efficient to assemble, easy to maintain, and has low manufacturing cost, but it can also ensure the stability and reliability of the clamping jaws 32 when clamping the laminate frame.

[0067] In some embodiments, the control device includes a controller and a detection component, and the controller is electrically connected to the conveyor 31 and the clamp 32, respectively, so that the conveyor 31 can convey the clamp 32 to a predetermined position under the control of the controller, and the clamp 32 can clamp or release the lamination frame under the control of the controller. The detection component is electrically connected to the controller, and the detection component is at least used to detect the double-glass photovoltaic modules placed on the feed table 11 and the discharge table 13, and to detect the clamp 32 located at the first position. When the detection component detects that the double-glass photovoltaic module is located on the feed table 11, the detection component triggers the controller to control the conveyor 31 to move the clamp 32 holding the lamination frame to the first position. After arriving at the first position, the controller controls the clamp 32 to release the lamination frame onto the double-glass photovoltaic module. After the lamination frame is placed, the controller controls the conveyor 31 to move the clamp 32 away from the first position. When the detection component detects that the double-glass photovoltaic component after lamination is conveyed to the discharge table 13, the detection component triggers the controller to control the conveying member 31 to drive the clamp 32 to move to the first position close to the discharge table 13. When the clamp 32 reaches the first position, the controller controls the clamp 32 to grab the lamination frame on the discharge table 13 and then controls the conveying member 31 to drive the clamp 32 away from the discharge table 13, thereby realizing automatic grabbing of the lamination frame, and the grabbing is efficient and accurate.

[0068] In some embodiments, the detection assembly includes a first position sensor and a second position sensor. The first position sensor is mounted on the feed table 11 and electrically connected to the controller. The first position sensor is used to detect a first position signal indicating that the double-glass photovoltaic module has arrived at the feed table 11, so that the controller, in response to the first position signal, controls the conveyor 31 to move the gripper 32 to a first position in a direction closer to the feed table 11. The second position sensor is mounted on the side of the mounting frame 20 near the feed table 11 and electrically connected to the controller. The second position sensor is used to detect a second position signal indicating that the gripper 32 on the feed table 11 is in the first position, so that the controller, in response to the second position signal, controls the gripper 32 to place the captured laminate frame (previously, the gripper assembly 30 on the feed table 11 may have already captured the laminate frame to be placed) on the double-glass photovoltaic module on the feed table 11. This embodiment uses the first and second position sensors to trigger the controller to execute corresponding operations, ensuring timely and reliable operation of the conveyor 31 and gripper 32 while ensuring the reliability and accuracy of the operation.

[0069] In some embodiments, the detection assembly further includes a third position sensor and a fourth position sensor. The third position sensor is mounted on the discharge platform 13 and electrically connected to the controller. The third position sensor is used to detect a third position signal indicating that the double-glass photovoltaic module has arrived at the discharge platform 13. In response to the third position signal, the controller controls the conveyor 31 to drive the clamping jaws 32 toward the double-glass photovoltaic module on the discharge platform 13. A fourth position sensor is mounted on a side of the mounting frame 20 near the discharge platform 13 and electrically connected to the controller. The fourth position sensor is used to detect a fourth position signal indicating that the clamping jaws 32 on the discharge platform 13 are in the first position. In response to the fourth position signal, the controller controls the clamping jaws 32 to open and grasp the laminate frame on the discharge platform 13 and to drive the clamping jaws 32 away from the discharge platform 13, thereby removing the laminate frame from the double-glass photovoltaic module. This embodiment uses the third and fourth position sensors to trigger the controller to execute corresponding operations, ensuring timely and reliable operation of the conveyor 31 and the clamping jaws 32.

[0070] In some embodiments, the first position sensor, the second position sensor, the third position sensor, and the fourth position sensor may include at least one of a photoelectric sensor, a laser sensor, and the like.

[0071] In some embodiments, a material storage device and a conveying mechanism 40 are also included. Along the first direction, the material storage device is installed on the side of the feed table 11 away from the laminating mechanism 12. Therefore, before placing the laminating frame on the double-glass photovoltaic module on the feed table 11 through the grabbing assembly 30, the gripping claw 32 of the grabbing assembly 30 can be controlled by the control device to clamp the laminating frame from the material storage device, so that when there is a double-glass photovoltaic module on the feed table 11, the laminating frame can be placed on the edge of the double-glass photovoltaic module in time. The conveying mechanism 40 is installed on the mounting frame 20 and is located on one side of the grabbing assembly 30 (the conveying mechanism 40 can be located above, in front of, or behind the grabbing assembly 30, depending on the actual situation, and is not limited to this in this embodiment). The conveying mechanism 40 is used to convey the laminating frame grabbed by the grabbing assembly 30 at the discharge table 13 to the material storage device. Thus, after the gripping assembly 30 grabs the laminate frame on the discharge platform 13 and separates the laminate frame from the double-glass photovoltaic module, the controller can control the conveying member 31 of the gripping assembly 30 to place the laminate frame held by the clamp 32 onto the conveying mechanism 40, and then return the laminate frame to the material storage device via the conveying mechanism 40. This not only improves the convenience of the gripping assembly 30 on the feed platform 11 in grabbing and placing the laminate frame, but also, after the gripping assembly 30 on the discharge platform 13 grabs the laminate frame, it can be conveyed back to the material storage device via the conveying mechanism 40, further improving the placement and separation efficiency of the laminate frame.

[0072] In some embodiments, the material storage device includes a storage cavity, and the conveying mechanism 40 includes a drive roller 41, a conveyor belt 42, and a motor. The drive rollers 41 include at least two, and the at least two drive rollers 41 are rotatably mounted on the mounting frame 20. Along a first direction, at least one drive roller 41 is located on a side of the discharge platform 13 away from the laminating mechanism 12, and at least one drive roller 41 is located on a side of the feed platform 11 away from the laminating mechanism 12. The conveyor belt 42 is sleeved over the at least two drive rollers 41. Along the first direction, the conveyor belt 42 extends from a side of the feed platform 11 away from the laminating mechanism 12 to a side of the discharge platform 13 away from the laminating mechanism 12. One end of the conveyor belt 42 is located on the feed platform 11, opposite the storage cavity. The motor includes an output shaft connected to the at least one drive roller 41. The motor is electrically connected to a control device (specifically, the motor is electrically connected to a controller of the control device). Under the control of the control device, the motor drives the output shaft to rotate the drive rollers 41. Thus, as the drive roller 41 rotates, the conveyor belt 42 is driven to rotate. After the grab assembly 30 places the laminate frame on the discharge platform 13 onto the conveyor belt 42, the conveyor belt 42 drives the laminate frame toward the infeed platform 11 until it is transferred into the storage cavity of the material storage device. In some embodiments, the material storage device can be a first-in, first-out material storage device, thereby ensuring that each laminate frame can be fully utilized according to the first-in, first-out principle.

[0073] In some embodiments, when the detection component includes a photoelectric sensor and the conveying member 31 includes a retractable robotic arm, the specific working process of the laminating machine is as follows:

[0074] When the double-glass photovoltaic module is transferred to the feeding table 11 of the laminator body 10 under the action of the assembly line (the feeding table 11 and the discharging table 13 of the laminator body 10 can respectively place 7 double-glass photovoltaic modules, and seven grabbing components 30 can be placed above the feeding table 11 and the discharging table 13 respectively), when the first double-glass photovoltaic module reaches the corresponding position on the feeding table 11, the photoelectric sensor is triggered, and the photoelectric sensor transmits a signal to the controller, which controls the retractable robotic arm above the feeding table 11. The lamination frame grasped by the clamp 32 is driven downward (when a controller is integrated in the retractable robotic arm, the photoelectric sensor can also directly transmit a signal to the retractable robotic arm). When the lamination frame is 0.5cm to 1cm away from the surface of the feed table 11 (such as one of the distances of 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, 1cm, etc.), the control device controls the clamp 32 on the retractable robotic arm to release the lamination frame, and the lamination frame can fall on the edge of the double-glass photovoltaic module. After the lamination frame is placed, the photoelectric sensor transmits a signal to the controller, and the controller controls the retractable robotic arm to pull up the clamp 32. The lamination frame enters the laminating mechanism 12 of the laminator along with the double-glass photovoltaic module to perform the normal lamination process. When the transmission track 50 is installed above the laminator body 10 across the feed table 11 and the discharge table 13, when the retractable robotic arm reaches a certain height, the photoelectric sensor can transmit a signal to the controller, and the controller controls the retractable robotic arm to slide from the feed table 11 to the discharge table 13 along the transmission track 50, and stop after reaching the corresponding position. Thus, the retractable robotic arm that has placed the lamination frame can return to the discharge table 13 to assist in the grabbing of the lamination frame, thereby improving the overall operational flexibility of the laminator.

[0075] After the lamination process of the laminating mechanism 12 is completed, the double-glass photovoltaic modules with the lamination frames attached will follow the conveyor belt 42 on the assembly line to the discharge platform 13 of the laminator. When the first double-glass photovoltaic module to come out reaches the corresponding position and triggers the photoelectric sensor, the photoelectric sensor will transmit a signal to the controller. The controller controls the telescopic robotic arm to extend downward (i.e., toward the discharge platform 13) to a certain length. The controller triggers the gripper 32 to grasp the lamination frame downward. At this time, the telescopic robotic arm retracts upward to a certain height to complete the grasping of the lamination frame. When all the lamination frames are grasped, the double-glass photovoltaic modules on the discharge platform 13 plane will be conveyed away from the laminator by the assembly line, and the entire lamination process is completely completed. Next, the controller controls the retractable robotic arm to drive the clamp 32 to place the lamination frame onto the conveyor belt 42 of the conveying mechanism 40. The lamination frame grasped by the clamp 32 will be conveyed to the material storage device on the side of the feed table 11 of the laminator under the action of the conveyor belt 42 to prepare for the next lamination. At this point, the entire automatic lamination frame placement process ends.

[0076] The utility model realizes full-automatic production of the lamination process, improves the efficiency and stability of photovoltaic component production, and reduces costs.
