Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and in particular to a control method for a laminator and a laminator. Background Technology

[0002] During the lamination process of photovoltaic modules, several flexible frames are usually set on a high-temperature cloth. When the component to be laminated is located in the lamination chamber, the flexible frames are placed around the component to be laminated to avoid poor lamination caused by concentrated stress during the pressure process.

[0003] The high-temperature fabric is in motion, which in turn causes the flexible frame on it to move as well. Only when the flexible frame and the part to be laminated are precisely aligned can the flexible frame be accurately fitted around the part to be laminated.

[0004] However, during the movement of the high-temperature fabric, it is prone to slippage. The controlled position of the high-temperature fabric deviates from its actual position, which in turn causes the flexible frame to be inaccurately fitted around the part to be laminated, reducing the lamination yield. Summary of the Invention

[0005] This invention provides a control method and a laminator for a laminator, aiming to solve the problem that in the existing lamination process, the flexible frame cannot be accurately fitted around the part to be laminated, which reduces the lamination yield.

[0006] A first aspect of the present invention provides a control method for a laminator, the laminator comprising: a high-temperature fabric, and a plurality of flexible frames fixed on the high-temperature fabric; the method comprising:

[0007] Step S1: Identify that the high-temperature cloth is in the initial position and control the high-temperature cloth to move at a first preset speed;

[0008] Step S2: Identify that the high-temperature fabric is located at the first synchronous initial position, and control the high-temperature fabric and the component to be laminated to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature fabric and the component to be laminated meet at the same preset position, and the component to be laminated eventually enters the flexible frame; the first preset speed is less than the second preset speed.

[0009] In this embodiment of the invention, the first preset speed is less than the second preset speed. That is, starting from the initial position before the high-temperature fabric moves synchronously with the component to be laminated, the high-temperature fabric is controlled to move slowly towards the first synchronous initial position. This provides sufficient time for accurate identification of the high-temperature fabric at the first synchronous initial position, ensuring accurate identification. Before each time the high-temperature fabric and the component to be laminated are controlled to move simultaneously at the second preset speed, the high-temperature fabric must be identified as having reached the first synchronous initial position. This identification of the high-temperature fabric at the first synchronous initial position eliminates positional deviations caused by fabric slippage. Only after eliminating positional deviations caused by fabric slippage is the high-temperature fabric and the component to be laminated controlled to move simultaneously at the second preset speed. This increases the probability that the flexible frame can be accurately fitted around the component to be laminated, improving the lamination yield.

[0010] Optionally, the laminator further includes: hanging rods disposed at both ends of the high-temperature fabric, a first hanging rod disposed at the first end of the high-temperature fabric, and a second hanging rod disposed at the second end of the high-temperature fabric, the first end and the second end being distributed sequentially along the direction of movement of the high-temperature fabric; step S1 includes:

[0012] Step S2 includes:

[0013] Step S21: Identify that the second hanging rod has moved to the first synchronous motion starting position, and control the high-temperature cloth and the workpiece to be laminated to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature cloth and the workpiece to be laminated meet at the same preset position, and the workpiece to be laminated finally enters the flexible frame.

[0018] Step S211: When the second detection component detects the second hanging rod, it controls the high-temperature cloth and the workpiece to be laminated to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature cloth and the workpiece to be laminated meet at the same preset position, and the workpiece to be laminated finally enters the flexible frame.

[0022] Step S21 includes:

[0023] Step S212: Based on the feedback from the first servo motor, the second hanging rod is identified to have moved to the first synchronous motion starting position. At this time, the high-temperature cloth and the workpiece to be laminated are controlled to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature cloth and the workpiece to be laminated meet at the same preset position, and the workpiece to be laminated finally enters the flexible frame.

[0024] Optionally, the laminator further includes: a frame; a third detection component is disposed on the frame at a position opposite to the second synchronous initial position; step S2 further includes:

[0025] Before controlling the high-temperature fabric and the component to be laminated to move simultaneously at a second preset speed, the third detection component confirms that the component to be laminated has been detected.

[0026] Optionally, the laminator further includes: a second transport assembly for transporting the parts to be laminated; the drive mechanism of the second transport assembly is a second servo motor; step S2 further includes:

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides a control method for a laminator, referring to... Figures 1 to 4 The laminator includes a high-temperature fabric 4 and several flexible frames 5 fixed on the high-temperature fabric 4. The total number of flexible frames 5 on a single high-temperature fabric 4 is determined based on the dimensions of the high-temperature fabric 4, the dimensions of the flexible frames 5, and the distance d1 between adjacent flexible frames 5. The distance d1 between adjacent flexible frames 5 refers to the spacing between adjacent flexible frames 5 in the direction of movement of the flexible frames 5. More specifically, the spacing between adjacent flexible frames 5 refers to the distance between the end of the first flexible frame 5 closest to the end of the second flexible frame 5 and the end of the second flexible frame 5 closest to the end of the first flexible frame 5 in the direction of movement of the flexible frames 5. The first flexible frame 5 and the second flexible frame 5 are adjacent.

[0045] Reference Figure 5 The control method for this laminator may include the following steps.

[0046] Step S1: Identify that the high-temperature cloth is in the initial position and control the high-temperature cloth to move at a first preset speed.

[0047] The initial position here specifically refers to a reference position selected before the high-temperature cloth 4 moves to the first synchronous initial position where it moves synchronously with the component to be laminated 6. In other words, along the direction of movement of the high-temperature cloth 4, this initial position is located in front of the first synchronous initial position where the high-temperature cloth 4 and the component to be laminated 6 move synchronously.

[0048] The identification of the high-temperature fabric 4 can be achieved using detection components. The movement speed of the first transport component 2, which transports the high-temperature fabric 4, can be controlled to move at a first preset speed. This first preset speed can be a relatively small speed. Once the high-temperature fabric 4 is detected to be in its initial position, a signal can be sent to the controller of the first transport component 2, which controls the transport of the high-temperature fabric 4. Based on this signal, the controller then controls the first transport component 2 to move at the first preset speed.

[0049] The main function of step S1 is to control the high-temperature cloth 4 to move slowly from the initial position before the first synchronous initial position of the high-temperature cloth 4 and the first synchronous initial position of the synchronous movement of the high-temperature cloth 4 and the first synchronous initial position of the synchronous movement of the high-temperature cloth 4 and the first synchronous initial position of the synchronous movement of the high-temperature cloth 4 and the first synchronous initial position of the synchronous movement of the first synchronous initial position, so as to provide sufficient time for accurate identification of the high-temperature cloth 4 at the first synchronous initial position, thereby ensuring that the high-temperature cloth 4 is accurately identified at the first synchronous initial position and avoiding the high-temperature cloth 4 moving too fast and failing to be accurately identified at the first synchronous initial position.

[0050] Step S2: Identify that the high-temperature fabric is located at the first synchronous initial position, and control the high-temperature fabric and the component to be laminated to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature fabric and the component to be laminated meet at the same preset position, and the component to be laminated eventually enters the flexible frame; the first preset speed is less than the second preset speed.

[0051] The first synchronous initial position refers to the starting position of the high-temperature cloth 4 at the moment when the high-temperature cloth 4 and the component to be laminated 6 begin synchronous movement. Identification of the high-temperature cloth 4 can also be achieved using detection components. The high-temperature cloth 4 can be controlled to move at a second preset speed by controlling the movement speed of the first transport component 2 transporting the high-temperature cloth 4. Similarly, the component to be laminated 6 can be controlled to move at a second preset speed by controlling the movement speed of the second transport component 1 transporting the second transport component 1.

[0052] Before each control of the high-temperature fabric 4 and the component to be laminated 6 at a second preset speed, it is necessary to identify that the high-temperature fabric 4 has moved to the first synchronous initial position and that it has moved to that position at the first preset speed. In this case, the distance between the position of the flexible frame 5 at the first synchronous initial position and the same preset position is equal to the distance between the position of the component to be laminated 6 and the same preset position. Both only need to move simultaneously at the same second preset speed to ensure that the flexible frame 5 on the high-temperature fabric 4 and the component to be laminated 6 meet at the same preset position, and that the component to be laminated 6 ultimately enters the flexible frame 5, achieving the goal of accurately fitting the component to be laminated 6 into the flexible frame 5. The aforementioned identification of the high-temperature fabric 4 at the first synchronous initial position is the process of eliminating positional deviations caused by slippage of the high-temperature fabric 4. Only after eliminating positional deviations caused by slippage of the high-temperature fabric 4 is the control of the high-temperature fabric 4 and the component to be laminated 6 to move simultaneously at the second preset speed, which increases the probability that the flexible frame 5 can be accurately fitted around the component to be laminated 6, improving the lamination yield.

[0053] Here, the laminate 6 is to be finally inserted into the flexible frame 5; specifically, the laminate 6 only needs to be located inside the flexible frame 5. For example... Figure 1 As shown, the third end 61 and the fourth end 63 of a component 6 to be laminated are both located inside a flexible frame 5 on the high-temperature fabric 4, meaning that the component 6 to be laminated is considered to ultimately enter the flexible frame 5. Here, the third end 61 and the fourth end 63 are arranged opposite each other along the direction of movement of the component 6 to be laminated. Figure 1 In the image below the component to be laminated 6, the direction indicated by the elliptical dashed line with an arrow is the direction of movement of the component to be laminated 6. For example, Figure 1 In this invention, the third end 61 of a component 6 to be laminated coincides with one end of the receiving area inside a flexible frame 5 on the high-temperature fabric 4; the geometric center 62 of a component 6 to be laminated coincides with the geometric center of the receiving area inside the flexible frame 5; and the fourth end 63 of the component 6 to be laminated coincides with the other end of the receiving area inside the flexible frame 5. Therefore, it is considered that the component 6 to be laminated ultimately enters the flexible frame 5. In this invention, referring to… Figure 1 The spacing d2 between adjacent components 6 to be laminated refers to the distance between adjacent components 6 in the direction of movement of the components 6. More specifically, the spacing between adjacent components 6 refers to the distance between the end of the first component 6 approaching the second component 6 and the end of the second component 6 approaching the first component 6 in the direction of movement of the components 6. The distance d1 between adjacent flexible frames 5 is equal to the spacing d2 between adjacent components 6. In this invention, by eliminating the slippage of the high-temperature fabric 4, it can be achieved that each component 6 can enter the interior of each corresponding flexible frame 5 on the high-temperature fabric 4.

[0054] The lower the first preset speed, the slower the high-temperature cloth 4 will approach the first initial synchronization position where the high-temperature cloth 4 and the component to be laminated 6 move synchronously. This provides sufficient time for accurate identification of the high-temperature cloth 4 at the first initial synchronization position. Therefore, the first preset speed is lower than the second preset speed. The difference between the second preset speed and the first preset speed depends on the actual situation and is not specifically limited here.

[0055] It should be noted that when the high-temperature cloth 4 is detected to be in the first synchronous initial position, a signal can also be sent to the controller of the first transport component 2 that controls the transport of the high-temperature cloth 4, and at the same time, a signal can be sent to the controller of the second transport component 1 that controls the transport of the laminate 6. Based on the above signals, the controller simultaneously controls the first transport component 2 that transports the high-temperature cloth 4 and the second transport component 1 that transports the laminate 6 to move at the second preset speed.

[0056] Before the aforementioned step S2, the laminate 6 can stop at the second synchronous initial position and wait for the high-temperature cloth 4 to move to the first synchronous initial position, or the laminate 6 can be kept in motion by controlling the speed, etc. At the same time that the high-temperature cloth 4 moves to the first synchronous initial position, the laminate 6 will also move to the second synchronous initial position. In this embodiment of the invention, no specific limitation is made.

[0057] Reference Figure 1 , Figure 2 , Figure 3 The direction indicated by the arrow marked in the dashed box on the second transport assembly 1, located in the lamination chamber 32, is the direction of movement of the high-temperature fabric 4. Optionally, refer to... Figures 1 to 4 The laminator also includes: hanging rods set at both ends of the high-temperature cloth 4, with the first hanging rod 21 set at the first end 41 of the high-temperature cloth 4 and the second hanging rod 22 set at the second end 42 of the high-temperature cloth 4, and the first end 41 and the second end 42 are distributed sequentially along the movement direction of the high-temperature cloth 4.

[0058] The aforementioned step S1 may include: step S11, identifying that the first hanging rod is located at the original starting position and the second hanging rod has not reached the first synchronous motion starting position, and controlling the high-temperature cloth to move at the first preset speed.

[0059] Step S2 includes:

[0060] Step S21: Identify that the second hanging rod has moved to the first synchronous motion starting position, and control the high-temperature cloth and the workpiece to be laminated to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature cloth and the workpiece to be laminated meet at the same preset position, and the workpiece to be laminated finally enters the flexible frame.

[0061] Specifically, detection components can be used to identify the first hanging rod 21 and the second hanging rod 22. The first end 41 and the second end 42 are sequentially distributed along the direction of movement of the high-temperature cloth 4, and consequently, the first hanging rod 21 and the second hanging rod 22 are also sequentially distributed along the direction of movement of the high-temperature cloth 4. When the first hanging rod 21 is identified as being in its original starting position and the second hanging rod 22 has not yet reached the first synchronous movement starting position, the distance between the second hanging rod 22 and the first movement starting position is to slow down the movement speed of the high-temperature cloth 4, ensuring accurate identification of the second hanging rod 22 at the first synchronous movement starting position for preparation or preparation. Upon identification that the first hanging rod 21 is in its original starting position, a signal can be sent to the controller of the first transport component 2 that controls the transport of the high-temperature cloth 4. Based on this signal, the controller controls the first transport component 2 that transports the high-temperature cloth 4 to move at a first preset speed.

[0062] Before each movement of the high-temperature fabric 4 and the component to be laminated 6 at the second preset speed, it is necessary to identify that the second hanging rod 22 has moved to the first synchronous movement starting position and that the high-temperature fabric 4 has moved to the first synchronous movement starting position at the first preset speed. In this case, the distance between the position of the flexible frame 5 at the first synchronous movement starting position and the same preset position is equal to the distance between the position of the component to be laminated 6 at this moment and the same preset position. As long as both move at the same second preset speed, it can be ensured that the flexible frame 5 on the high-temperature fabric 4 and the component to be laminated 6 meet at the same preset position, and the component to be laminated 6 eventually enters the flexible frame 5, achieving the goal of accurately placing the component to be laminated 6 into the flexible frame 5. The above-mentioned identification of the second hanging rod 22 being at the first synchronous movement starting position is the process of eliminating the positional deviation caused by the slippage of the high-temperature fabric 4. After eliminating the positional deviation caused by the slippage of the high-temperature fabric 4, the high-temperature fabric 4 and the component to be laminated 6 are controlled to move at the second preset speed simultaneously, which increases the probability that the flexible frame 5 can be accurately fitted around the component to be laminated 6, improving the lamination yield.

[0063] The positions of the first hanging rod 21 and the second hanging rod 22 are used here to represent the relative positions of the first end 41 and the second end 42 of the high-temperature cloth 4 along the movement direction of the high-temperature cloth 4, respectively. This more detailed division of the position of the high-temperature cloth 4 helps to more accurately identify the actual position of the high-temperature cloth 4, which can further ensure that the flexible frame 5 can be accurately fitted around the part to be laminated 6, thereby improving the lamination yield.

[0064] Optional, refer to Figures 2 to 4The laminator may further include: a frame (not shown in the figure), on which a first detection component 71 is disposed at a position opposite to the original starting position, and on which a second detection component 72 is disposed at a position opposite to the first synchronous movement starting position. The first detection component 71 is used to detect the first hanging rod 21, and the second detection component 72 is used to detect the second hanging rod 22. For example, the first detection component 71 can detect the first hanging rod 21 by photoelectric signals, and the second detection component 72 can detect the second hanging rod 22 by photoelectric signals, etc. Optionally, the first hanging rod 21 can be an iron hanging rod, and the first detection component 71 can be a magnetic induction switch; both are readily available and have low cost. Optionally, the first detection component 71 can also be an infrared detection component, a visual detection component, etc., making the first detection component 71 flexible and diverse. When the first detection component 71 is a magnetic induction switch, both the first hanging rod 21 and the first detection component 71 protrude from the first transport assembly 2. Therefore, if the first transport assembly 2 is made of a magnetic material such as iron, there is virtually no impact on the detection of the first hanging rod 21 by the first detection component 71, resulting in high detection accuracy. Optionally, the second hanging rod 22 can be an iron hanging rod, and the second detection component 72 can be a magnetic induction switch; both are readily available and inexpensive. Optionally, the second detection component 72 can also be an infrared detection component, a visual detection component, etc., offering flexibility and variety. When the second detection component 72 is a magnetic induction switch, both the second hanging rod 22 and the second detection component 72 protrude from the first transport assembly 2. Therefore, if the first transport assembly 2 is made of a magnetic material such as iron, there is virtually no impact on the detection of the second hanging rod 22 by the second detection component 72, resulting in high detection accuracy.

[0065] Optionally, step S11 may include:

[0066] Step S111: When the first detection component detects the first hanging rod and the second detection component does not detect the second hanging rod, the high-temperature cloth is controlled to move at the first preset speed.

[0067] The aforementioned step S21 may include:

[0068] Step S211: When the second detection component detects the second hanging rod, it controls the high-temperature cloth and the workpiece to be laminated to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature cloth and the workpiece to be laminated meet at the same preset position, and the workpiece to be laminated finally enters the flexible frame.

[0069] Using the first detection component 71 can improve the accuracy of detecting the first hanging rod 21, and using the second detection component 72 can improve the accuracy of detecting the second hanging rod 22. This can improve the accuracy of detecting the real-time position of the high-temperature cloth 4, and further ensure that the flexible frame 5 can be accurately fitted around the part to be laminated 6, thereby improving the lamination yield.

[0070] It should be noted that when the first detection component 71 detects the first hanging rod 21, it sends a signal to the controller of the first transport assembly 2 that controls the transport of the high-temperature fabric 4. The controller then controls the first transport assembly 2 to move at a first preset speed. When the second detection component 72 detects the second hanging rod 22, it sends a signal to the controller of the first transport assembly 2 that controls the transport of the high-temperature fabric 4, and simultaneously sends a signal to the controller of the second transport assembly 1 that controls the transport of the laminate 6. Based on these signals, the controllers simultaneously control the first transport assembly 2 and the second transport assembly 1 to move at a second preset speed.

[0071] When the first detection component 71 detects the first hanging rod 21, it will emit a rising edge pulse. Therefore, the emission of a rising edge pulse by the first detection component 71 indicates that the first detection component 71 has detected or identified the first hanging rod 21. When the second detection component 72 detects the second hanging rod 22, it will emit a rising edge pulse. Therefore, the emission of a rising edge pulse by the second detection component 72 indicates that the second detection component 72 has detected or identified the second hanging rod 22.

[0072] Optional, refer to Figures 2 to 4 The laminator may further include a frame (not shown in the figure) and a first transport assembly 2. A first detection component 71 is disposed on the frame at a position opposite to the original starting position. The first detection component 71 can be referred to in the aforementioned relevant descriptions and can achieve the same or similar beneficial effects; therefore, it will not be described again here to avoid repetition. The drive mechanism of the first transport assembly 2 is a first servo motor (not shown in the figure). High-temperature cloth 4 is disposed on the first transport assembly 2. Since the first servo motor has higher control precision, it can improve the alignment accuracy between the workpiece 6 to be laminated and the corresponding flexible frame 5, further improving the lamination yield. The number of high-temperature cloths 4 disposed on the first transport assembly 2 is not limited. For example, the first transport assembly 2 may be provided with four high-temperature cloths 4, with each hanging rod simultaneously fixing the rear end of the previous high-temperature cloth 4 and the front end of the next high-temperature cloth 4.

[0073] Optionally, step S11 may include:

[0074] Step S112: When the first detection component detects the first hanging rod, it controls the high-temperature cloth to move at the first preset speed.

[0075] The aforementioned step S21 may include:

[0076] Step S212: Based on the feedback from the first servo motor, the second hanging rod is identified to have moved to the first synchronous motion starting position. At this time, the high-temperature cloth and the workpiece to be laminated are controlled to move simultaneously at the second preset speed, so that the flexible frame on the high-temperature cloth and the workpiece to be laminated meet at the same preset position, and the workpiece to be laminated finally enters the flexible frame.

[0077] Using the first detection component 71 can improve the accuracy of detecting the first hanging rod 21. Because the first servo motor has higher control precision, the feedback from the first servo motor can also improve the accuracy of identifying the second hanging rod 22. This improves the accuracy of detecting the real-time position of the high-temperature fabric 4, further ensuring that the flexible frame 5 can be accurately fitted around the component to be laminated 6, thus improving the lamination yield. Specifically, the feedback from the first servo motor can be the distance traveled by the first transport component 2 within each small time interval.

[0078] It should be noted that when the first detection component 71 detects the first hanging rod 21, it sends a signal to the controller of the first transport component 2 that controls the transport of the high-temperature fabric 4. This controller then controls the first transport component 2 to move at a first preset speed. Based on the feedback from the first servo motor, when the second hanging rod 22 is detected, it also sends a signal to the controller of the first transport component 2 that controls the transport of the high-temperature fabric 4. Simultaneously, it sends a signal to the controller of the second transport component 1 that controls the transport of the laminate 6. Based on these signals, the controllers simultaneously control the first transport component 2 and the second transport component 1 to move at a second preset speed.

[0079] Optionally, the laminator may further include: a frame on which a third detection component (not shown in the figure) is disposed at a position opposite to the second synchronous initial position. The aforementioned step S2 may further include:

[0080] Before controlling the high-temperature fabric and the component to be laminated to move simultaneously at a second preset speed, the third detection component confirms that the component to be laminated has been detected.

[0081] Before each movement of the high-temperature fabric 4 and the component to be laminated 6 at a second preset speed, a third detection component detects that the component to be laminated 6 has reached the second synchronous initial position. The distance between the second synchronous initial position and the aforementioned same preset position is equal to the distance between the position of the flexible frame 5 at the first synchronous initial position and the aforementioned same preset position. In this case, the component to be laminated 6 and the high-temperature fabric 4 only need to move simultaneously at the same second preset speed to ensure that the flexible frame 5 on the high-temperature fabric 4 and the component to be laminated 6 meet at the same preset position, and the component to be laminated 6 eventually enters the flexible frame 5, achieving the goal of accurately fitting the component to be laminated 6 into the flexible frame 5. The above-mentioned detection of the component to be laminated 6 reaching the second synchronous initial position by the third detection component is the process of eliminating the positional deviation caused by the slippage of the component to be laminated 6. After eliminating the positional deviation caused by the slippage of the component to be laminated 6, the high-temperature fabric 4 and the component to be laminated 6 are controlled to move simultaneously at the second preset speed, which increases the probability that the flexible frame 5 can be accurately fitted around the component to be laminated 6, improving the lamination yield.

[0082] The third detection component here is a detection component capable of identifying the component 6 to be laminated, such as a monitor with a camera. It should be noted that in this case, the aforementioned first detection component 71 can be used to detect the movement of the high-temperature fabric 4 to its initial position. Alternatively, the second detection component 72 or feedback from the first servo motor can be used to detect the movement of the high-temperature fabric 4 to its first synchronous initial position.

[0083] Optional, refer to Figure 1 The laminator also includes a second transport assembly 1 for transporting the component 6 to be laminated. The drive mechanism of the second transport assembly 1 is a second servo motor (not shown in the figure). Step S2 may further include:

[0084] Before controlling the high-temperature fabric and the component to be laminated to move simultaneously at the second preset speed, the component to be laminated is identified to have moved to the second synchronous initial position based on the feedback from the second servo motor.

[0085] Because the second servo motor has higher control precision, its feedback can improve the accuracy of identifying the component 6 to be laminated. This improves the accuracy of identifying the real-time position of the component 6, further ensuring that the flexible frame 5 can be accurately fitted around the component 6, thus improving the lamination yield. Specifically, the feedback from the second servo motor can be the distance traveled by the second transport component 1 within each small time interval.

[0086] Before each movement of the high-temperature fabric 4 and the component to be laminated 6 at a second preset speed, based on feedback from the second servo motor, it is determined that the component to be laminated 6 has reached the second synchronous initial position. The distance between the second synchronous initial position and the aforementioned same preset position is equal to the distance between the position of the flexible frame 5 at the first synchronous initial position and the aforementioned same preset position. In this case, as long as the component to be laminated 6 and the high-temperature fabric 4 move simultaneously at the same second preset speed, it can be ensured that the flexible frame 5 on the high-temperature fabric 4 and the component to be laminated 6 meet at the same preset position, and the component to be laminated 6 eventually enters the flexible frame 5, achieving the goal of accurately fitting the component to be laminated 6 into the flexible frame 5. The above-mentioned identification of the component to be laminated 6 reaching the second synchronous initial position based on feedback from the second servo motor is the process of eliminating the positional deviation caused by the slippage of the component to be laminated 6. Only after eliminating the positional deviation caused by the slippage of the component to be laminated 6 is the movement of the high-temperature fabric 4 and the component to be laminated 6 simultaneously at the second preset speed, which increases the probability that the flexible frame 5 can be accurately fitted around the component to be laminated 6, improving the lamination yield.

[0087] It should be noted that, in this case, the aforementioned first detection component 71 can be used to detect the movement of the high-temperature cloth 4 to its initial position. Alternatively, the second detection component 72 or feedback from the first servo motor can be used to detect the movement of the high-temperature cloth 4 to its first synchronous initial position.

[0088] Optionally, the aforementioned first transport component 2 is composed of multiple synchronous belts. Compared to the prior art, where the first transport component 2 is composed of a single conveyor belt, the present invention uses multiple synchronous belts, which greatly reduces the slippage of the high-temperature fabric 4 and further increases the probability that the flexible frame 5 can be accurately fitted around the component to be laminated 6, thereby improving the lamination yield. It should be noted that the specific number of synchronous belts in the first transport component 2 is not limited. For example, the first transport component 2 may be composed of 3, 4, 5, 6, or 7 synchronous belts.

[0089] Optionally, the aforementioned second transport component 1 consists of multiple synchronous belts. Compared to the prior art, where the second transport component 1 consists of a single conveyor belt, the present invention uses multiple synchronous belts, which significantly reduces slippage of the component 6 to be laminated, further increasing the probability that the flexible frame 5 can be accurately fitted around the component 6 to be laminated, thereby improving the lamination yield. It should be noted that the specific number of synchronous belts in the second transport component 1 is not limited. For example, the second transport component 1 may consist of 3, 4, 5, 6, or 7 synchronous belts.

[0090] Optionally, before step S2, the method may further include: correcting the four sides of the component 6 to be laminated, so as to avoid a decrease in lamination yield due to the skewness of the four sides of the component 6 to be laminated.

[0091] The present invention also provides a laminator for photovoltaic modules, which employs any of the aforementioned laminator control methods.

[0092] For example, refer to Figure 1 The laminator may further include a lamination assembly, a first transport assembly 2, and the lamination assembly being disposed adjacent to each other in direction L1. The lamination assembly includes an upper lamination chamber 31 and a lower lamination chamber 32 disposed opposite to each other. The upper lamination chamber 31 and the lower lamination chamber 32 are disposed opposite to each other in direction L2, where direction L1 and direction L2 intersect, and the included angle between them is not specifically limited; for example, direction L1 and direction L2 may be perpendicular to each other. The first transport assembly 2 is disposed around the lower lamination chamber 32.

[0093] Optionally, each flexible frame 5 includes a receiving area for the laminate 6. The size of the receiving area for the laminate 6 within each flexible frame 5 can be greater than or equal to the size of the laminate 6. Optionally, each flexible frame 5 also includes an excess portion located outside the receiving area. The size of the excess portion in any direction is 0.5% to 1.5% of the size of the receiving area in that direction. This size range not only facilitates precise alignment between the flexible frame 5 and the laminate 6 but also prevents waste of the high-temperature fabric 4.

[0094] For example, the size of the surplus portion in the first direction is 0.5%, 0.7%, 0.8%, 0.9%, 0.96%, 0.99%, 1.0%, 1.05%, or 1.5% of the size of the receiving area in the first direction, and the size of the surplus portion in the second direction perpendicular to the first direction is 0.5%, 0.6%, 0.72%, 0.9%, 0.96%, 0.99%, 1.0%, 1.05%, or 1.5% of the size of the receiving area in the second direction.

[0095] Optionally, the material of the flexible frame 5 is selected from high-temperature resistant materials such as silicone sheets, so that the flexible frame 5 can basically withstand the heat impact during the lamination process and has a long service life.

[0096] Optionally, the flexible frame 5 can be sewn onto the high-temperature fabric 4, or the flexible frame 5 can be pasted onto the high-temperature fabric 4; the connection method between the two is simple.
