Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to an integrated tooling and conveying device for photovoltaic module lamination. Background Technology
[0002] As the core energy conversion unit of a solar power generation system, the manufacturing quality of photovoltaic modules directly affects the system's power generation efficiency and lifespan. In the module encapsulation process, lamination is a critical step determining product reliability, requiring the bonding of materials such as glass, solar cells, and backsheets into a laminate using high temperature and pressure. Given the structural characteristics of double-glass modules, rigid protective fixtures must be installed around the module during lamination to prevent glass breakage due to laminator pressure, while also suppressing edge air bubbles and ensuring the integrity of the encapsulation interface.
[0003] Currently, the industry commonly uses steel frames as lamination fixtures. The process flow is as follows: operators in the loading area attach multiple independent steel fixtures one by one to the edge of the photovoltaic module to form a closed protective structure. Then, the photovoltaic module and fixture assembly are placed on the laminator conveyor belt. Please refer to [link / reference needed] for details. Figure 1 As shown, the conveyor belt sequentially feeds the modules into the preheating section, vacuuming section, hot pressing section, and cooling section to complete the lamination. After lamination, the fixtures must be manually disassembled in the unloading area and recycled. During operation, operators must visually calibrate the positioning reference of the fixtures on the conveyor belt to prevent positional misalignment between the laminator's pressing area and the photovoltaic modules.
[0004] Therefore, conventional technical solutions have significant limitations. First, the installation and disassembly of tooling require dedicated personnel, resulting in high labor costs for loading and unloading. Second, the alignment accuracy of the steel tooling and conveyor belt depends on the operator's experience, and misalignment defects in lamination are easily caused by positioning deviations. Finally, the steel tooling is heavy, and frequent movement and disassembly can easily damage the tooling, further increasing production costs. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an integrated tooling and conveying device for photovoltaic module lamination, which can reduce the labor cost of loading and unloading processes, eliminate the need for manual alignment, reduce lamination misalignment defects caused by positioning deviations, and prevent damage to the tooling caused by frequent movement and disassembly, thereby reducing production costs.
[0006] To solve the above-mentioned technical problems, this utility model provides an integrated tooling and conveying device for photovoltaic module lamination, including a conveyor belt and protective tooling. Multiple sets of the protective tooling are spaced apart on the conveyor belt. Each protective tooling includes two sets of limiting components spaced back and forth along the conveying direction of the conveyor belt. The conveyor belt is provided with multiple receiving slots for the corresponding installation of the limiting components. Each limiting component includes two horizontal bars arranged back and forth opposite each other and used to abut against the front or rear edge of the photovoltaic module, a lifting device installed in the receiving slot and used to lift the horizontal bars above the conveyor belt, and a pressure sensor installed on the upper side of the horizontal bars and used to communicate with the lifting device.
[0007] As an improvement to the above solution, the limiting component also includes a photosensitive sensor mounted on the upper side of the crossbar and used for communication with the lifting device.
[0008] As an improvement to the above solution, when the output end of the lifting device is in the lower position, the horizontal bar is located in the receiving groove and the sensing end of the pressure sensor is flush with or extends out of the receiving groove from the conveyor belt.
[0009] As an improvement to the above solution, the inner side of the crossbar is perpendicular to the conveying direction of the conveyor belt.
[0010] As an improvement to the above solution, the horizontal bar has longitudinal bars extending inward at both ends, and the inner side of the longitudinal bars is perpendicular to the inner side of the horizontal bar.
[0011] As an improvement to the above solution, each set of limiting components is provided with two lifting devices, which are respectively set at the junction of the horizontal and vertical bars.
[0012] As an improvement to the above scheme, the distance between the front and rear longitudinal strips in each set of limiting components is greater than the length of the longitudinal strips.
[0013] As an improvement to the above solution, the pressure sensor and the photosensitive sensor are located in the middle of the horizontal bar.
[0014] As an improvement to the above solution, the pressure sensor is located at the rear of the middle of the horizontal bar, and the photosensitive sensor is located at the front of the middle of the horizontal bar.
[0015] Implementing this utility model has the following beneficial effects:
[0016] This utility model's integrated tooling and conveying device for photovoltaic module lamination utilizes the interaction of a conveyor belt, limiting components, receiving groove, crossbars, lifting device, and pressure sensor to automatically limit the photovoltaic modules transferred into the limiting components.

It also eliminates the need for manual alignment, reducing lamination misalignment defects caused by positioning deviations, and preventing damage to the tooling due to frequent movement and disassembly, thereby reducing production costs.

[0029] like Figures 2 to 8 As shown in the figure, an integrated tooling and conveying device for photovoltaic module lamination in this embodiment of the present invention includes a conveyor belt 1 and protective tooling. In fact, the conveyor belt 1 is used to transport the photovoltaic module from back to front and through the external lamination device. Inside the external lamination device, the conveyor belt 1 drives the photovoltaic module to pass through the preheating section, the vacuuming section, the hot pressing section and the cooling section in sequence, so that the photovoltaic module can complete the lamination.
[0030] Multiple sets of protective fixtures are spaced apart on conveyor belt 1. In practice, one set of protective fixtures is used to restrict the position of a photovoltaic module. The protective fixtures are installed on the conveyor belt of conveyor belt 1 and move synchronously with the conveyor belt. The spacing between adjacent protective fixtures can be determined according to actual production needs.
[0031] The protective fixture includes two sets of limiting components 2 spaced back-to-back along the conveyor belt 1. The conveyor belt 1 has multiple receiving slots 3 for the limiting components 2 to be installed one-to-one. Each limiting component 2 includes two horizontal bars 4 arranged opposite each other and used to abut against the front or rear edge of the photovoltaic module, a lifting device 5 installed in the receiving slot 3 to lift the horizontal bars 4 above the conveyor belt 1, and a pressure sensor 6 installed on the upper side of the horizontal bars 4 for communication with the lifting device 5. In fact, the distance between the two horizontal bars 4 of the limiting component 2 is determined by the width of the photovoltaic module. Since the position of the limiting component 2 on the conveyor belt 1 is fixed, by simply controlling the step distance of the conveyor belt 1 each time, the photovoltaic module placed in the limiting component 2 can be moved to the lower position of the lamination station of the lamination device without manual alignment, reducing lamination misalignment defects caused by positioning deviation. The two horizontal bars 4 can restrict the front and rear sides of the photovoltaic module and prevent the photovoltaic module from being crushed and the corners from being damaged. Of course, the protection is less than that of a four-sided frame, but it still provides sufficient protection. There are also some existing technologies that use two horizontal bars 4 on the front and rear sides to protect the photovoltaic module, which will not be described in detail here.
[0032] The lifting device 5 can be a cylinder, an electric telescopic rod, etc. When the crossbar 4 is not needed, the output end of the lifting device 5 is in the lower position and the crossbar 4 is in the receiving groove 3. When the crossbar 4 is needed, the output end of the lifting device 5 is in the upper position and the crossbar 4 extends out of the receiving groove 3. It should be noted that the conveyor belt 1, lifting device 5, pressure sensor 6, etc. of this utility model are all connected to the control components of the external lamination device. In fact, the power supply and automatic operation of each component can be achieved by adding a separate power supply, wireless communication connection, etc., which can break through the dependence of traditional lamination tooling on fixed cables and manual monitoring, and improve the automation level of the photovoltaic module lamination tooling and conveyor integrated device of this utility model.
[0033] The specific working principle of the integrated tooling and conveying device for photovoltaic module lamination of this utility model is as follows: Initially, both the front and rear crossbars 4 are in the receiving groove 3 on the conveyor belt 1. The operator lays the photovoltaic module flat on the surface of the conveyor belt 1 through a mechanical transfer mechanism or manual operation. The conveyor belt 1 drives the photovoltaic module to move from back to front. When the rear edge of the photovoltaic module contacts the pressure sensor 6 built into the rear crossbar 4, the pressure sensor 6 detects the contact pressure value in real time and generates a trigger signal. Through the control loop, it is linked with the front lifting device 5 to drive the front crossbar 4 to disengage from the receiving groove 3 and lift it to a set height, forming a limit on the front edge of the photovoltaic module. The movement continues until the front edge of the photovoltaic module contacts the front crossbar 4. Upon contact, as the photovoltaic module moves away from the rear horizontal bar 4, the pressure sensor 6 on the rear horizontal bar 4 detects the pressure change. Through the pressure sensor 6, it communicates with the lifting device 5. The lifting device 5 then moves the horizontal bar 4 away from the receiving groove 3 and limits the rear edge of the photovoltaic module. Then, the conveyor belt 1 moves the photovoltaic modules on the limiting component 2 step by step and places the photovoltaic modules on the limiting component 2 one by one until the photovoltaic module leaves the external laminating device. The two lifting devices 5 then move the front and rear horizontal bars 4 back into the receiving groove 3, remove the photovoltaic module, and reset the limiting device. Without the need for manual disassembly and movement of the limiting component 2, the module follows the conveyor belt 1 back to the initial position and enters the next work cycle.
[0034] This utility model's integrated tooling and conveying device for photovoltaic module lamination utilizes the interaction of a conveyor belt 1, a limiting component 2, a receiving groove 3, a crossbar 4, a lifting device 5, and a pressure sensor 6 to automatically limit the photovoltaic modules transferred into the limiting component 2. The limiting component 2 can reset according to a set step and cycle, eliminating the need for dedicated personnel to install, disassemble, or move the tooling, thus reducing labor costs in the loading and unloading process. It also eliminates the need for manual alignment, reducing lamination misalignment defects caused by positioning deviations, and preventing damage to the tooling due to frequent movement and disassembly, thereby reducing production costs.
[0035] Furthermore, the limiting component 2 preferably includes a photosensitive sensor 7 mounted on the upper side of the crossbar 4 and used for communication with the lifting device 5. In practice, the photosensitive sensor 7 can detect changes in the light illuminating the crossbar 4. In actual production, the external laminating device is located in a workshop with a certain light intensity, while the light intensity in the internal processing space of the external laminating device is lower. When the crossbar 4 on the conveyor belt 1 leaves the external laminating device, the photosensitive sensor 7 on the crossbar 4 detects the change in light intensity from weak to strong and controls the corresponding lifting device 5 to move the crossbar 4 down into the receiving groove 3, facilitating the unloading of the photovoltaic modules.
[0036] Preferably, when the output end of the lifting device 5 is in the lower position, the horizontal bar 4 is located in the receiving groove 3 and the sensing end of the pressure sensor 6 is flush with or extends out of the receiving groove 3, so that when the photovoltaic module moves from back to front and passes the horizontal bar 4, the lower side of the photovoltaic module contacts the pressure sensor 6, ensuring that the sensing end of the pressure sensor 6 can sense the change in gravity of the photovoltaic module.
[0037] It should be noted that the height of the horizontal bar 4 matches the height of the photovoltaic module, ensuring that the horizontal bar 4 restricts the front and rear edges of the photovoltaic module; the depth of the receiving groove 3 is 2.1-2.5 times the height of the horizontal bar 4, ensuring that the horizontal bar 4 can enter and leave the receiving groove 3; the thickness of the conveyor belt 1 is more than 3 times the height of the horizontal bar 4, providing sufficient installation space and connection strength for the limiting component 2.
[0038] Specifically, the inner side of the horizontal bar 4 is preferably perpendicular to the conveying direction of the conveyor belt 1. In fact, the inner side of the horizontal bar 4 of the limiting component 2 in front of each set of protective fixtures is the rear side, used to limit the front edge of the photovoltaic module, and the inner side of the horizontal bar 4 of the limiting component 2 behind each set of protective fixtures is the front side, used to limit the rear edge of the photovoltaic module, thus ensuring the ability to limit the front and rear edges of the photovoltaic module.
[0039] It is worth mentioning that the horizontal bar 4 preferably has longitudinal bars 8 extending inward at both ends, and the inner side of the longitudinal bars 8 is perpendicular to the inner side of the horizontal bar 4. In fact, the horizontal bar 4 of the limiting component 2 in front of each set of protective fixtures has longitudinal bars 8 extending backward at both ends to limit the two front corners of the photovoltaic module. In fact, the horizontal bar 4 of the limiting component 2 at the rear of each set of protective fixtures has longitudinal bars 8 extending forward at both ends to limit the two rear corners of the photovoltaic module. By adding longitudinal bars 8, the restriction on the four corners of the photovoltaic module is increased, and the restriction effect on the photovoltaic module is further improved.
[0040] Specifically, each set of limiting components 2 preferably has two lifting devices 5, which are respectively set at the junction of the horizontal bar 4 and the vertical bar 8. In fact, the two lifting devices 5 of each set of limiting components 2 operate synchronously, so that the horizontal bar 4 and the two vertical bars 8 are subjected to more even force, thereby improving the stability of the lifting of the horizontal bar 4 and the two vertical bars 8.
[0041] More specifically, in each set of limiting components 2, the distance between the front and rear longitudinal strips 8 is preferably greater than the length of the longitudinal strips 8. When the conveyor belt of the conveyor belt 1 bends and deforms during operation, the longitudinal strips 8 in the limiting components 2 need to be adjusted accordingly. Since the distance between the front and rear longitudinal strips 8 is greater than the length of the longitudinal strips 8, the deformation space of the longitudinal strips 8 increases when they deform with the conveyor belt 1. After the length of the longitudinal strips 8 is reduced, the bending radius of the longitudinal strips 8 increases when the conveyor belt of the conveyor belt 1 bends, thereby reducing the stress concentration of the longitudinal strips 8 during the bending process. At the same time, the larger distance also avoids mutual interference between the longitudinal strips 8 when the conveyor belt of the conveyor belt 1 bends, so that each longitudinal strip 8 can independently and smoothly follow the bending deformation of the conveyor belt of the conveyor belt 1, ensuring the effective limiting and stable support of the conveyor belt of the limiting components 2 for the conveyor belt of the conveyor belt 1.
[0042] Furthermore, the pressure sensor 6 and the photosensor 7 are preferably located in the middle of the horizontal bar 4. Since the photovoltaic module is positioned between the horizontal bars 4 after passing through them, the force and light intensity in the middle of the horizontal bar 4 are relatively uniform. Therefore, the pressure sensor 6 and the photosensor 7 located in the middle of the horizontal bar 4 can accurately monitor changes in pressure and light intensity.
[0043] Furthermore, the pressure sensor 6 is preferably located at the rear of the middle of the horizontal bar 4. Since the photovoltaic module moves from back to front relative to the horizontal bar 4 when it is being loaded, the pressure sensor 6 can sense the change in the force exerted by the photovoltaic module on the horizontal bar 4 more quickly. The photosensor 7 is preferably located at the front of the middle of the horizontal bar 4. Since the conveyor belt 1 drives the photovoltaic module placed between the horizontal bars 4 to move from back to front, the photosensor 7 can sense the change in the intensity of external light more quickly when the horizontal bar 4 passes through the external laminating device.
[0044] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
