[0023] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0024] The photovoltaic module includes front glass, battery cells and back glass. The battery cells have a light-receiving surface and a backlight surface. The front glass is connected to the light-receiving surface of the battery cell through an adhesive film, and the back glass is connected to the backlight surface of the battery cell through an adhesive film.

[0025] To record production information for photovoltaic modules, such as which machine completed each step and when, modules are equipped with identification codes, such as barcodes. Typically, three identification codes are provided: one on the busbar on the light-receiving side of the cell, another on the back glass, and a third on the frame. Because the light-receiving side of the cell is covered with a translucent film, barcode scanners cannot accurately read the code through the film.

[0026] Therefore, see Figure 1 The hot spot device provided in one embodiment of the present application includes a conveying mechanism 10 and a hot spot mechanism 20. The conveying mechanism 10 is used to convey glass 50, on which a film is laid. The hot spot mechanism 20 is installed on the conveying mechanism 10, and is combined with the conveying mechanism 10. Figure 2 The hot stamping mechanism 20 includes a driving component 21 and a hot stamping component 22. The driving component 21 is connected to the hot stamping component 22. The driving component 21 is used to drive the hot stamping component 22 to move along the height direction of the conveying mechanism 10. The hot stamping component 22 is used to press against the part where the identification code of the adhesive film and the battery cell are facing each other, so as to perform hot stamping on the part where the identification code of the adhesive film and the battery cell are facing each other.

[0027] Optionally, the driving component 21 is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. Of course, in other embodiments, the driving component 21 may also be a screw module, etc., and is not limited thereto.

[0028] In the above-mentioned hot stamping device, the conveying mechanism 10 conveys the glass 50 forward. When the glass 50 is conveyed to the area where the hot stamping mechanism 20 is located, the conveying mechanism 10 stops conveying. Then, the driving component 21 drives the hot stamping component 22 to move in the height direction toward the glass 50 until the hot stamping component 22 is pressed against the portion where the adhesive film and the identification code of the battery cell are directly opposite, thereby hot stamping the portion where the adhesive film and the identification code of the battery cell are directly opposite to the glass 50 until it becomes transparent. After the hot stamping is completed, the driving component 21 drives the hot stamping component 22 to move in the height direction away from the glass 50, and the conveying mechanism 10 continues to convey the glass 50 forward to the next process. In this way, the hot stamping mechanism 20 can hot stamp the portion where the adhesive film and the identification code of the battery cell are directly opposite to the glass 50 until it becomes transparent. In this way, the barcode scanner can recognize the identification code of the battery cell through the transparent adhesive film, ensuring that the identification code on the light-receiving surface of the battery cell can be accurately recognized.

[0029] In one embodiment, see Figure 2The hot stamping component 22 includes a heating element and a hot stamping head 221 for contacting the adhesive film. The heating element is connected to the hot stamping head 221, and the heating element is used to heat the hot stamping head 221. The hot stamping head 221 is connected to the driving component 21. During hot stamping, the heating element heats the hot stamping head 221. After the hot stamping head 221 is heated to a preset temperature, the driving component 21 drives the hot stamping head 221 to move in the height direction toward the glass 50 until the hot stamping head 221 is pressed against the position where the adhesive film and the identification code of the battery cell are opposite. By providing the hot stamping head 221, direct contact between the heating element and the adhesive film is avoided, thereby preventing damage to the heating element and extending the service life of the heating element.

[0030] Optionally, the heating element is a heating rod. Further, the ironing head 221 is provided with a first perforation, and the heating rod is arranged in the ironing head 221 through the first perforation, so as to avoid the safety hazard caused by the heating rod leaking out.

[0031] Optionally, the ironing head 221 is a high-temperature resistant metal block. For example, the ironing head 221 is made of copper, aluminum, tungsten, iron, etc.

[0032] In one embodiment, the hot stamping mechanism 20 further includes a temperature measuring element. The temperature measuring element is disposed within the hot stamping head 221 and is used to measure the temperature of the hot stamping head 221. Specifically, the hot stamping head 221 has a second perforation, through which the temperature measuring element is disposed. During hot stamping, the temperature measuring element measures the temperature of the hot stamping head 221 in real time. When the temperature of the hot stamping head 221 measured by the temperature measuring element reaches a preset temperature, the hot stamping head 221 applies hot stamping to the portion of the adhesive film that is aligned with the identification code on the light-receiving surface of the cell.

[0033] Optionally, the temperature measuring element is a thermocouple, a thermal resistor, a thermistor, etc. Of course, in other embodiments, the temperature measuring element may also be other types of devices, and is not limited thereto.

[0034] In one embodiment, the hot stamping mechanism 20 further includes a thermostat. The thermostat is in communication with the temperature measuring element and the heating element. During hot stamping, the temperature measuring element measures the temperature of the hot stamping head 221 in real time and sends the measured temperature to the thermostat. The thermostat determines whether the temperature of the hot stamping head 221 has reached a preset temperature. If the temperature of the hot stamping head 221 has reached the preset temperature, the hot stamping head 221 will hot stamp the portion where the film and the identification code of the battery cell are aligned. If the temperature of the hot stamping head 221 has not reached the preset temperature, the heating element will continue to heat the hot stamping head 221 until the temperature of the hot stamping head 221 reaches the preset temperature. In this way, the thermostat can control the temperature of the hot stamping head 221 to prevent the hot stamping head 221 from being too hot and melting the film, and to prevent the hot stamping head 221 from being too cold and leaving a black mark on the film.

[0035] Furthermore, the hot ironing mechanism 20 also includes a relay. The relay is electrically connected to the heating element. It is understood that the heating element is connected to the power supply via the relay. The relay is in communication with the thermostat, and the thermostat controls the on and off of the relay by measuring the temperature of the hot ironing head 221 by the temperature measuring element. During hot ironing, the temperature measuring element measures the temperature of the hot ironing head 221 in real time. When the temperature of the hot ironing head 221 is lower than the preset temperature, the thermostat sends a signal to the relay, the relay closes, the heating element is connected to the power supply, and the heating element heats the hot ironing head 221. When the temperature of the hot ironing head 221 reaches the preset temperature, the thermostat sends a signal to the relay, the relay is disconnected, the heating element is disconnected from the power supply, and the heating element stops heating the hot ironing head 221.

[0036] In one embodiment, see Figure 2 The hot ironing mechanism 20 further includes a heat insulator 23. Optionally, the heat insulator 23 may be a glass wool board, etc. The heat insulator 23 is disposed between the drive assembly 21 and the hot ironing assembly 22. Specifically, the upper portion of the heat insulator 23 is connected to the output end of the drive assembly 21, and the lower portion of the heat insulator 23 is connected to the hot ironing assembly 22. The provision of the heat insulator 23 can block the heat generated by the hot ironing assembly 22, preventing the heat from being transferred to the drive assembly 21, thereby preventing the performance of the drive assembly 21 from being affected.

[0037] In one embodiment, the conveying mechanism 10 includes a fixed frame and a conveying module. The conveying module and the hot mechanism 20 are both mounted on the fixed frame. Optionally, the conveying module is a pulley module or a sprocket module, but is not limited thereto.

[0038] In one embodiment, see Figure 2 The hot ironing device further includes a mounting bracket 30. The mounting bracket 30 is mounted on the fixing frame, and the hot ironing mechanism 20 is mounted on the mounting bracket 30. In this way, the hot ironing mechanism 20 is mounted on the conveying mechanism 10 through the mounting bracket 30, thereby improving the convenience of installing the hot ironing mechanism 20.

[0039] In one embodiment, see Figure 2 The mounting bracket 30 includes a first frame 31 and a second frame 32 connected to the first frame 31 . The first frame 31 is mounted on the conveying mechanism 10 , and the driving assembly 21 is mounted on the second frame 32 .

[0040] Optionally, see Figure 1 and Figure 2The first frame 31 is provided with a first strip-shaped hole 311, which extends perpendicular to the conveying direction of the conveying mechanism 10. For ease of understanding, the conveying direction is represented by S. The fixing frame is provided with a first fixing hole, and a first fixing member is provided within the first fixing hole and the first strip-shaped hole 311. The first fixing member can be a screw or bolt. This arrangement allows the installation position of the mounting bracket 30 to be adjusted according to the different specifications and sizes of the glass 50, thereby adjusting the position of the hot-pressing mechanism 20, so that the hot-pressing mechanism 20 is compatible with hot-pressing films on glass 50 of different specifications and sizes.

[0041] Of course, in other embodiments, the first frame 31 is provided with a first through hole, and there are at least two first through holes. All first through holes are spaced apart in a direction perpendicular to the conveying direction of the conveying mechanism 10, and a first fixing member is provided in the first fixing hole and the first through hole connected thereto.

[0042] Optionally, see Figure 2 The second frame 32 is provided with a second strip-shaped hole 321 extending along the height of the second frame 32. The drive assembly 21 is provided with a second fixing hole. A second fixing member is provided within the second fixing hole and the second strip-shaped hole 321. The second fixing member can be a screw or bolt. This arrangement allows the height of the drive assembly 21 to be adjusted according to usage requirements.

[0043] Of course, in other embodiments, the second frame 32 is provided with at least two second through holes, and all the second through holes are spaced apart along the height direction of the second frame 32. A second fixing member is provided in the second fixing hole and the second through hole communicating therewith.

[0044] After the glass 50 is conveyed by the conveying mechanism 10, the glass 50 may become skewed, thereby affecting the accuracy of the hot spot. Figure 1 The hot spot device includes a correction mechanism 40, which is mounted on a fixed frame of the conveying mechanism 10 and is used to correct the four sides of the glass 50. In this way, the accuracy of the hot spot position can be guaranteed.

[0045] Further, see Figure 1 The alignment mechanism 40 includes a first alignment component 41 and a second alignment component 42. At least two first alignment components 41 are provided, and each of the first alignment components 41 is disposed on both sides of the conveying direction of the conveying mechanism 10 to align the short sides of the glass 50. Two second alignment components 42 are provided, and each of the two second alignment components 42 is disposed at intervals along the conveying direction of the conveying mechanism 10 to align the long sides of the glass 50.

[0046] Optionally, see Figure 1 and Figure 3The first alignment assembly 41 includes a first driving member 411 and a first alignment wheel 412. The first driving member 411 is mounted on a fixed frame, and the first alignment wheel 412 is located at the output end of the first driving member 411. When the conveying mechanism 10 conveys the glass 50 to the area where the hot mechanism 20 is located, the first driving member 411 drives the first alignment wheel 412 to move toward the short side of the glass 50, so that the first alignment wheel 412 presses against the short side of the glass 50, thereby aligning the short side of the glass 50.

[0047] Optionally, the second alignment assembly 42 includes a second driving member and a second alignment wheel. The second driving member is mounted on a fixed frame, and the second alignment wheel is located at the output end of the second driving member. When the conveying mechanism 10 conveys the glass 50 to the area where the hot mechanism 20 is located, the second driving member drives the second alignment wheel to rise or fall to block the long side of the glass 50, thereby aligning the long side of the glass 50.

[0048] The present application also provides a photovoltaic module production device, comprising the hot spot device of any of the above embodiments.

[0049] In the photovoltaic module production equipment described above, the conveying mechanism 10 conveys the glass 50 forward. When the glass 50 is conveyed to the area where the hot stamping mechanism 20 is located, the conveying mechanism 10 stops conveying. Then, the driving component 21 drives the hot stamping component 22 to move in the height direction toward the glass 50 until the hot stamping component 22 is pressed against the portion where the adhesive film and the identification code of the cell are opposite, so as to hot stamp the portion where the adhesive film and the identification code of the cell are opposite to each other until it becomes transparent. After the hot stamping is completed, the driving component 21 drives the hot stamping component 22 to move in the height direction away from the glass 50, and the conveying mechanism 10 continues to convey the glass 50 forward to the next process. In this way, the hot stamping mechanism 20 can hot stamp the portion where the adhesive film and the identification code of the cell are opposite to each other until it becomes transparent, so that the barcode scanner can recognize the identification code of the cell through the adhesive film, ensuring that the identification code on the light-receiving surface of the cell can be accurately recognized.
