Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic substrate transmission line and transmission device. Background Technology

[0002] Currently, in the manufacturing process of photovoltaic modules, transmission lines are required to transport photovoltaic substrates; however, due to the structural limitations of existing transmission lines, the area of ​​a single photovoltaic substrate transported is typically no more than 1m². 2 This cannot meet the transmission requirements for large-area photovoltaic substrates. Furthermore, in actual manufacturing, due to the layout of the factory and the feeding requirements of other processing equipment such as coating equipment, photovoltaic substrates may need to be fed into the transmission line from multiple different feeding directions. Therefore, the current transmission line with a single feeding direction can no longer meet the continuously changing manufacturing process requirements of photovoltaic substrates and the entire photovoltaic module.

[0003] To address the above problems, there is an urgent need for a photovoltaic substrate transmission line and transmission device. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic substrate transmission line and transmission device that can meet the transmission requirements of large-area photovoltaic substrates and enable the photovoltaic substrates to be transmitted from various feeding directions onto various conveying rollers.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] frame;

[0008] A conveying roller assembly includes a frame and a plurality of conveying roller components. The frame is connected to the machine frame, and the conveying roller components are rotatably connected to the frame. The conveying roller components are evenly spaced along the length of the frame. Each conveying roller component is used to convey a photovoltaic substrate, and the total area of ​​the conveying roller components matches the area of ​​the photovoltaic substrate.

[0009] A rotating assembly, the fixed end of which is located on the frame, and the driving end of the rotating assembly is connected to the frame base. The rotating assembly is used to rotate the frame base around the Z-axis.

[0010] As an optional solution, the photovoltaic substrate transmission line further includes a driving assembly for synchronously driving the rotation of each of the conveying rollers; the driving assembly includes:

[0011] The first driving component has its fixed end located on the frame base;

[0012] The system includes an active multi-wedge wheel, a driven multi-wedge wheel, a first multi-wedge belt, and a second multi-wedge belt. The driving end of the first driving member is connected to the active multi-wedge wheel. One end of each conveying roller is fitted with a driven multi-wedge wheel. The first multi-wedge belt is fitted between the active multi-wedge wheel and two adjacent driven multi-wedge wheels, and the second multi-wedge belt is fitted between the other two adjacent driven multi-wedge wheels.

[0013] As an optional solution, the inner ring surfaces of the first and second multi-wedge belts are provided with annular grooves, and the outer circumferential surfaces of the driving and driven multi-wedge wheels are provided with annular protrusions, which are engaged in the annular grooves.

[0014] As an optional feature, the involute wedge angle α of the annular groove is 40°-45°.

[0015] As an optional solution, the number of annular slots on a single first multi-tie band or a single second multi-tie band is N, the distance between the center lines of two adjacent annular slots is A = 2.24mm to 2.44mm, and the total width of the N annular slots is W = N × Amm.

[0016] As an optional solution, the driving component further includes:

[0017] The first tensioning wheel is rotatably connected to the frame base, and the first multi-tightening belt abuts against the outer side of the first tensioning wheel. The first tensioning wheel is used to adjust the tension of the first multi-tightening belt.

[0018] As an optional solution, the driving component further includes:

[0019] The second tensioning wheel is rotatably connected to the frame base. Each of the second multi-tightening belts abuts against the outer top surface of one of the second tensioning wheels. The second tensioning wheel is used to adjust the tension of the second multi-tightening belt.

[0020] As an optional solution, the rotating component includes:

[0021] The second driving component has its fixed end located on the frame;

[0022] The device includes a driving gear and a driven gear. The driving end of the second driving member is connected to the driving gear. The driving gear is rotatably connected to the frame around the Z-axis and meshes with the driven gear. The driven gear is connected to the bottom end of the frame. The second driving member is used to drive the driving gear to rotate around the Z-axis, and the number of teeth of the driving gear is less than the number of teeth of the driven gear.

When both the first sensor and the second sensor detect a signal and feed it back to the main controller, the main controller adjusts the transmission of the photovoltaic substrate by the conveying rollers.

[0026] As an optional solution, a transition roller is rotatably connected to the entrance end of the frame. An encoder is provided on the transition roller and is communicatively connected to the main controller. When the photovoltaic substrate on the previous photovoltaic substrate transmission line is transmitted to the transition roller, the encoder can dynamically capture the transmission rate of the photovoltaic substrate and feed it back to the main controller so that the main controller can adjust the transmission rate of the two adjacent photovoltaic substrate transmission lines to be the same.

[0027] The beneficial effects of this utility model are as follows:

[0028] The photovoltaic substrate transmission line of this invention uses conveying rollers rotatably connected to a frame to transport photovoltaic substrates. These rollers are evenly spaced along the length of the frame, with their total area matching the area of ​​the photovoltaic substrate. This allows for the transport of individual photovoltaic substrates with larger areas, thus meeting the transmission requirements for large-area photovoltaic substrates. Simultaneously, the drive end of a rotating assembly is connected to the frame, driving the frame to rotate around the Z-axis. This rotation, in turn, causes the conveying rollers to rotate around the Z-axis, adjusting the feeding direction of the entire photovoltaic substrate transmission line. This allows the photovoltaic substrates to be transported from various feeding directions according to requirements, thereby meeting the continuously changing manufacturing process requirements of the photovoltaic substrates and the entire photovoltaic module.

[0029] The transmission device of this invention includes multiple modular photovoltaic substrate transmission lines, which allows for better independence of each photovoltaic substrate transmission line. This enables the rapid replacement and installation of a single photovoltaic substrate transmission line without affecting the transmission operation of other photovoltaic substrate transmission lines.

[0047] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] like Figures 1 to 7 As shown, this embodiment provides a photovoltaic substrate transmission line 10, which can transmit large-area photovoltaic substrates 20 and meet the feeding requirements of various different feeding directions, thereby meeting the continuously changing manufacturing process requirements of the photovoltaic substrate 20 and the entire photovoltaic module. Specifically, the photovoltaic substrate 20 can be a glass substrate used in the photovoltaic module manufacturing process.

[0050] Specifically, such as Figures 1 to 3 As shown, the photovoltaic substrate transmission line 10 includes a frame 1, a conveying roller assembly 2, and a rotating assembly 3. The conveying roller assembly 2 includes a frame base 21 and multiple conveying roller components 22. The frame base 21 is connected to the frame 1, and the conveying roller components 22 are rotatably connected to the frame base 21. The conveying roller components 22 are evenly spaced along the length of the frame base 21, and each conveying roller component 22 is used to convey the photovoltaic substrate 20. The total area of ​​all conveying roller components 22 matches the area of ​​the photovoltaic substrate 20. The fixed end of the rotating assembly 3 is located on the frame 1, and the driving end of the rotating assembly 3 is connected to the frame base 21. The rotating assembly 3 is used to rotate the frame base 21 around the Z-axis, thereby driving the entire conveying roller component 22 to rotate along the Z-axis. Here, the actual structure of the frame 1 is not limited; the frame 1 can specifically be a lightweight, high-strength, and corrosion-resistant aluminum profile frame 1. Specifically, the length direction of the frame base 21 is... Figure 2 and Figure 3 As shown by arrow B in the diagram.

[0051] Compared with the prior art, the photovoltaic substrate transmission line 10 in this embodiment changes the transmission structure and feeding method of the photovoltaic substrate 20. By rotatably connecting the conveying rollers 22 to the frame 21, the photovoltaic substrate 20 is conveyed through each conveying roller 22. Furthermore, the conveying rollers 22 are evenly distributed along the length of the frame 21, and the total area of ​​each conveying roller 22 matches the area of ​​the photovoltaic substrate 20, so as to be able to convey a single photovoltaic substrate 20 with a larger area, thereby meeting the transmission requirements of large-area photovoltaic substrates 20. At the same time, the driving end of the rotating component 3 is connected to the frame 21, so that the rotating component 3 drives the frame 21 to rotate around the Z-axis, thereby driving each conveying roller 22 to rotate around the Z-axis as a whole. This allows the feeding direction of the entire photovoltaic substrate transmission line 10 to be adjusted, so that the photovoltaic substrate 20 can enter the conveying rollers 22 from various different feeding directions according to feeding needs, thereby meeting the continuously changing manufacturing process requirements of the photovoltaic substrate 20 and the entire photovoltaic module. The photovoltaic substrate transmission line 10 in this embodiment is suitable for a single area of ​​2.88m². 2 Transmission of the photovoltaic substrate 20.

[0052] The following is a detailed description of the conveyor roller component 22:

[0053] Specifically, such as Figure 2 As shown, the conveying roller assembly 22 includes a rotating shaft 221 and multiple rollers 222. The rotating shaft 221 is rotatably connected to the frame 21. Multiple rollers 222 are spaced along the length of the rotating shaft 221. Rotation of the rotating shaft 221 synchronously drives the rotation of each roller 222, thereby supporting and conveying the photovoltaic substrate 20 through each roller 222. Here, the specific number of rotating shafts 221 and the number of rollers 222 on each rotating shaft 221 are not limited.

[0054] Furthermore, the roller 222 is anti-static, that is, the roller 222 is made of black anti-static ultra-high molecular weight polyethylene (UPE) material, so as to avoid static electricity between the roller 222 and the photovoltaic substrate 20, thereby ensuring the transmission effect of the roller 222 on the photovoltaic substrate 20.

[0055] The rotating component 3 is described in detail below:

[0056] Specifically, such as Figures 3 to 5As shown, the rotating assembly 3 includes a second driving member 31, a driving gear 32, and a driven gear 33. The fixed end of the second driving member 31 is located on the frame 1, and the driving end of the second driving member 31 is connected to the driving gear 32. The driving gear 32 is rotatably connected to the frame 1 around the Z-axis and meshes with the driven gear 33. The driven gear 33 is connected to the bottom end of the frame 21. The second driving member 31 is used to drive the driving gear 32 to rotate around the Z-axis, thereby driving the driven gear 33 and the frame 21 to rotate around the Z-axis, thereby driving each conveying roller 22 on the frame 21 to rotate around the Z-axis as a whole, so as to adjust the different feeding directions of the photovoltaic substrate 20 on each conveying roller 22.

[0057] In this embodiment, the feeding direction requirements of both 0° and 90° rotation angles can be taken into account at the same time; the second driving component 31 can be a servo motor, and a high-precision reducer is connected between the driving end of the second driving component 31 and the active gear 32 to ensure that the speed transmitted to the active gear 32 is appropriate and that the speed is not too high.

[0058] Furthermore, such as Figure 4 and Figure 5 As shown, the number of teeth of the driving gear 32 is less than the number of teeth of the driven gear 33. That is, the driving gear 32 is a small gear and the driven gear 33 is a large gear. This allows the large gear to rotate at a slower speed and increase its torque through the gear ratio between the large and small gears. This ensures the rotational stability and reliability of the large gear on the entire frame 21 and reduces the output power of the second drive unit 31, thus saving resources.

[0059] In this embodiment, the photovoltaic substrate transmission line 10, such as... Figure 1 and Figure 2 As shown, each synchronously rotating shaft 221 drives its respective roller 222 to rotate, thereby achieving an ultra-large conveying area structure for the photovoltaic substrate 20, which can cover a single area of ​​2.88m². 2 Transmission of large-format photovoltaic substrate 20.

[0060] In this embodiment, the photovoltaic substrate transmission line 10, such as... Figures 3 to 5 As shown, by combining the conveying roller 22 with the rotating component 3, the different feeding directions of the photovoltaic substrate 20 can be met, thereby changing the feeding direction of the photovoltaic substrate 20 onto the conveying roller 22 according to the changes in the manufacturing process of the photovoltaic module; and, the structural arrangement between the conveying roller 22 and the rotating component 3 can be made more reasonable and compact, ensuring the structural compactness of the entire photovoltaic substrate transmission line 10.

[0061] It is worth noting that the specification of this embodiment is attached. Figures 1 to 9The specific structures of the frame 1 and the base 21 involved are different. The figure is only for structural illustration. In actual operation, it is only necessary to ensure that the base 21 and the conveying roller 22 on it can rotate around the Z-axis relative to the frame 1 under the drive of the rotating component 3. Here, the structure of the frame 1 and the base 21 is not specifically limited.

[0062] The following is a detailed description of driver component 4:

[0063] Specifically, such as Figures 1 to 3 , Figure 6 As shown, the photovoltaic substrate transmission line 10 also includes a drive component 4. The fixed end of the drive component 4 is located on the frame 21. The drive end of the drive component 4 is connected to the rotation shaft 221 of each conveying roller component 22. The drive component 4 is used to synchronously drive each conveying roller component 22 to rotate so that each roller 222 supports and transmits the photovoltaic substrate 20.

[0064] Current drive components typically employ gear meshing transmission structures to drive the synchronous rotation of various conveying rollers. However, the collision of meshing tooth surfaces in gear meshing transmission structures generates high-frequency noise, which is significantly amplified, especially under high-speed and heavy-load conditions. Furthermore, due to the concentration of contact stress on the meshing tooth surfaces, wear or even failure of the meshing tooth surfaces occurs during long-term operation, reducing the service life of the gear meshing transmission structure.

[0065] To solve the above problems, such as Figures 1 to 3 , Figure 6 As shown, the drive assembly 4 in this embodiment includes a first drive member 41, an active multi-wedge wheel 42, a driven multi-wedge wheel 43, a first multi-wedge belt 44, and a second multi-wedge belt 45. The fixed end of the first drive member 41 is located on the frame base 21, and the drive end of the first drive member 41 is connected to the active multi-wedge wheel 42. A driven multi-wedge wheel 43 is sleeved at one end of the rotating shaft 221 of each conveying roller member 22. A first multi-wedge belt 44 is sleeved between the active multi-wedge wheel 42 and two adjacent driven multi-wedge wheels 43, and a second multi-wedge belt 45 is sleeved between the other two adjacent driven multi-wedge wheels 43.

[0066] Compared with the prior art, the photovoltaic substrate transmission line 10 in this embodiment is as follows: Figure 6As shown, a flexible transmission method using multiple wedges and pulleys replaces the current gear meshing transmission method. By setting up an active multi-wedge pulley 42, a driven multi-wedge pulley 43, a first multi-wedge belt 44, and a second multi-wedge belt 45 that work together, the flexible transmission of multiple wedges and pulleys can ensure low-noise operation under high-speed and heavy-load conditions, reducing noise by 30%-40% compared to gear meshing transmission. Furthermore, due to the large contact area between the multiple wedges and pulleys, stress concentration at the contact points can be reduced, thereby improving the service life of the drive component 4 and the entire photovoltaic substrate transmission line 10. Thus, the drive component 4 can be suitable for the high-lifetime, low-noise transmission requirements of the photovoltaic substrate 20.

[0067] And, as Figure 6 As shown, through the transmission action of the first multi-tie belt 44 and each of the second multi-tie belts 45, a first driving member 41 synchronously drives each rotating shaft 221 to rotate, thereby reducing the number of first driving members 41, reducing the cost of the entire photovoltaic substrate transmission line 10 and improving the overall structural compactness of the photovoltaic substrate transmission line 10; and ensuring good rotational synchronization of each rotating shaft 221, thereby ensuring the synchronicity and uniformity of the transmission of the photovoltaic substrate 20 by each roller 222.

[0068] In this embodiment, the first driving component 41 can be a servo motor, and a high-precision reducer is connected between the driving end of the first driving component 41 and the active multi-whet wheel 42 to ensure that the speed transmitted to the active multi-whet wheel 42 is appropriate and that the speed is not too high.

[0069] Furthermore, both the first multi-tight belt 44 and the second multi-tight belt 45 are made of nitrile rubber, which allows for greater friction between them. This enables a flexible, surface-contact transmission between the multi-tight belts and the multi-tight pulleys, ensuring the stability and reliability of the connection. Additionally, the elastic deformation of the first and second multi-tight belts 44 and 45 absorbs the impact vibrations generated during transmission, further reducing noise. This eliminates the periodic impacts present in current gear meshing transmission methods, significantly attenuating high-frequency components in the noise spectrum at 2000 rpm, thereby reducing the noise level to 65 dB–72 dB.

[0070] Specifically, spiral steel wire reinforcement layers are embedded inside both the first multi-tie belt 44 and the second multi-tie belt 45 to increase their structural strength. Furthermore, both the driving multi-tie wheel 42 and the driven multi-tie wheel 43 are made of aluminum alloy to ensure their structural strength. That is, compared to the first multi-tie belt 44 and the second multi-tie belt 45, the driving multi-tie wheel 42 and the driven multi-tie wheel 43 have higher structural strength, resulting in better durability. In other words, during long-term transmission operation, it is usually the first multi-tie belt 44 and the second multi-tie belt 45 that need to be replaced, making replacement simple and convenient. Moreover, since the price of the first multi-tie belt 44 and the second multi-tie belt 45 is lower than that of gears in the prior art, the cost of the entire photovoltaic substrate transmission line 10 can be saved. The first multi-wedge belt 44 and the second multi-wedge belt 45 may have the same or different structures; the driving multi-wedge wheel 42 and the driven multi-wedge wheel 43 may have the same or different structures.

[0071] Specifically, such as Figure 6 and Figure 7 As shown, annular grooves 46 are provided on the inner annular surfaces of the first multi-wedge belt 44 and the second multi-wedge belt 45, and annular protrusions 47 are provided on the outer circumferential surfaces of the driving multi-wedge wheel 42 and the driven multi-wedge wheel 43. The annular protrusions 47 engage with the annular grooves 46. This ensures that the multi-wedge belt and the multi-wedge wheel form a flexible surface contact transmission, increasing the contact area between the multi-wedge belt and the multi-wedge wheel to 4 to 6 times that of current gear meshing transmission methods. This significantly reduces the pressure per unit area at the contact points between the multi-wedge belt and the multi-wedge wheel, effectively avoiding stress concentration. This prevents wear or even failure at the contact points between the multi-wedge belt and the multi-wedge wheel during long-term operation, thus ensuring a longer service life for the entire drive assembly 4. In this embodiment, the service life of the drive assembly 4 during continuous operation is increased by 150% to 200% compared to the gear meshing transmission structure.

[0072] Furthermore, by providing annular grooves 46 on the inner ring surfaces of both the first multi-tie belt 44 and the second multi-tie belt 45, and by making both the first multi-tie belt 44 and the second multi-tie belt 45 made of nitrile rubber, the friction of the first multi-tie belt 44 and the second multi-tie belt 45 can be significantly increased. This results in a substantial reduction in the resonance peak amplitude in the entire drive assembly 4 compared to the resonance peak amplitude in the gear meshing transmission structure. Consequently, the fatigue failure period of the first multi-tie belt 44 and the second multi-tie belt 45 can be extended to 2 to 3 times that of the current gear meshing transmission method.

[0073] Furthermore, such as Figure 7As shown, the involute wedge angle α of the annular groove 46 is 40°-45°, which allows for a suitable groove depth, ensuring a proper fit between the annular protrusion 47 and the annular groove 46. This eliminates the need for additional lubricating oil between the protrusion 47 and the groove 46, enabling lubrication-free transmission between the multi-belt and multi-wheel. This reduces oil contamination and maintains the cleanliness of the entire photovoltaic substrate transmission line 10. Furthermore, it lowers the maintenance costs of the entire photovoltaic substrate transmission line 10, and because frequent lubrication is not required, the maintenance cycle of the entire drive assembly 4 can be extended to 3-4 years. In this embodiment, the involute wedge angle α of the annular groove 46 can specifically be 40°.

[0074] Furthermore, such as Figure 7 As shown, the number of annular slots 46 on a single first multi-tie band 44 or a single second multi-tie band 45 is N. The distance between the center lines of two adjacent annular slots 46 is A = 2.24mm to 2.44mm, and the total width W of the N annular slots 46 is W = N × A mm. This ensures that the total width of the annular slots 46 on the first multi-tie band 44 or the second multi-tie band 45 is appropriate, thereby guaranteeing a large contact area between the annular slots 46 and the annular protrusions 47. In this embodiment, the number of annular slots 46 on a single first multi-tie band 44 or a single second multi-tie band 45 is N = 5, A = 2.34mm, and the total width W of the N annular slots 46 is W = N × A = 5 × 2.34 = 11.7mm. Here, the specific number of annular slots 46 is not limited and needs to be determined according to the actual operating conditions of the entire drive assembly 4, and the number of annular protrusions 47 should match the number of annular slots 46.

[0075] Specifically, such as Figure 6 As shown, the drive assembly 4 also includes a first tensioning wheel 48, which is rotatably connected to the frame 21. A first multi-tightening belt 44 abuts against the outer surface of the first tensioning wheel 48. The first tensioning wheel 48 is used to adjust the tension of the first multi-tightening belt 44. Furthermore, the drive assembly 4 also includes a second tensioning wheel 49, which is rotatably connected to the frame 21. Each second multi-tightening belt 45 abuts against the outer top surface of a second tensioning wheel 49. The second tensioning wheel 49 is used to adjust the tension of the second multi-tightening belt 45.

[0076] The tension of the first multi-belt 44 is adjusted by the first tensioning wheel 48 to ensure that the first multi-belt 44 maintains a certain transmission torque output; at the same time, the tension of the second multi-belt 45 is adjusted by the second tensioning wheel 49 to ensure that the second multi-belt 45 maintains a certain transmission torque output; thereby ensuring the rotational smoothness of the first multi-belt 44 and the second multi-belt 45 on each conveying roller component 22, and thus ensuring the smooth transmission of the photovoltaic substrate 20 by each conveying roller component 22.

[0077] Specifically, because the first and second multi-tight belts 44 and 45 are made of nitrile rubber, they have elastic deformation. Therefore, the first tensioning wheel 48 and the second tensioning wheel 49 can be pre-installed in appropriate positions so that the first tensioning wheel 48 can abut against the first multi-tight belt 44 to ensure tension of the first multi-tight belt 44; and the second tensioning wheel 49 can abut against the second multi-tight belt 45 to ensure tension of the second multi-tight belt 45. When it is necessary to disassemble and replace the first multi-tight belt 44 and the second multi-tight belt 45, the abutting action of the first tensioning wheel 48 and the second tensioning wheel 49 can be directly released, and the corresponding multi-tight belt can be directly removed from the multi-tight belt. This makes the replacement of the first multi-tight belt 44 and the second multi-tight belt 45 relatively simple and convenient. Compared with the replacement of meshing gears in the prior art, the replacement and maintenance time of the drive assembly 4 can be shortened by about 50%.

[0078] Specifically, such as Figure 6 As shown, there are two first tensioning pulleys 48, arranged at intervals, and the first multi-belt 44 is tensioned inside the two first tensioning pulleys 48. This ensures better adjustment of the tension force of the first tensioning pulleys 48 on the first multi-belt 44, further guaranteeing the transmission torque output of the first multi-belt 44. A second tensioning pulley 49 adjusts the tension force of a second multi-belt 45.

[0079] In this embodiment, the photovoltaic substrate transmission line 10 has annular grooves 46 on the inner ring surfaces of the first multi-tie belt 44 and the second multi-tie belt 45, and annular protrusions 47 on the outer circumferential surfaces of the driving multi-tie wheel 42 and the driven multi-tie wheel 43, so that the annular protrusions 47 are engaged with the annular grooves 46; and the materials of the first multi-tie belt 44 and the second multi-tie belt 45 are both nitrile rubber; so as to ensure that the multi-tie belts and multi-tie wheels form a surface contact flexible transmission, thereby increasing the contact area between the multi-tie belts and multi-tie wheels to a certain extent. Currently, the gear meshing transmission method is 4 to 6 times longer, which can ensure a longer service life of the entire drive assembly 4, thereby increasing the service life of the drive assembly 4 by 150% to 200%. Furthermore, through the flexible transmission and large contact area of ​​the multi-belt and multi-wheel, as well as the elastic deformation of the first multi-belt 44 and the second multi-belt 45, noise can be reduced by 30% to 40%, thereby ensuring a significant attenuation of high-frequency components in the noise spectrum under 2000 rpm conditions, reducing the noise level to 65 dB to 72 dB.

[0080] In this embodiment, the photovoltaic substrate transmission line 10 is designed so that the annular protrusion 47 engages with the annular groove 46, and the involute wedge angle α of the annular groove 46 is 40°-45°. This eliminates the need for additional lubricating oil between the annular protrusion 47 and the annular groove 46, ensuring lubrication-free transmission between the multi-belt and the multi-wheel. This reduces oil contamination and eliminates the need for frequent maintenance and lubrication, extending the maintenance cycle of the entire drive assembly 4 to 3-4 years.

[0081] In this embodiment, the photovoltaic substrate transmission line 10 is equipped with flexible first multi-tight straps 44 and second multi-tight straps 45, and the clamping action of the first tensioning wheel 48 and the second tensioning wheel 49 can be directly released, so that the corresponding multi-tight straps can be directly removed from the multi-tight wheels. This ensures that the replacement of the first multi-tight straps 44 and the second multi-tight straps 45 is relatively simple and convenient, thereby reducing the replacement and maintenance time of the drive component 4 by about 50%.

[0082] Example 2

[0083] This embodiment provides a transmission device comprising multiple photovoltaic substrate transmission lines 10 as described in Embodiment 1 above. Each photovoltaic substrate transmission line 10 is arranged in parallel along the transmission direction of the photovoltaic substrate 20, that is, the photovoltaic substrate transmission lines 10 are arranged sequentially to form a series transmission structure. Each photovoltaic substrate transmission line 10 can only accommodate and transmit one photovoltaic substrate 20, thereby enabling orderly and continuous transmission of the photovoltaic substrate 20. The transmission direction of the photovoltaic substrate 20 is parallel to the length direction of the frame 21.

[0084] Furthermore, such as Figure 8As shown, the transmission device also includes a main controller 50. The electrical modules of each photovoltaic substrate transmission line 10 are connected to the main controller 50 via aviation connectors. That is, the electrical modules of each photovoltaic substrate transmission line 10 can be plugged into and used directly on the main controller 50, enabling quick connection and use between the electrical modules and the main controller 50. The main controller 50 adopts a common PLC main control structure in the prior art, and the electrical modules use a common electrical module structure in the prior art. The specific working principles of the main controller 50 and the electrical modules will not be described in detail here.

[0085] By arranging the various photovoltaic substrate transmission lines 10 in parallel along the transmission direction of the photovoltaic substrate 20 to form a series transmission structure, each photovoltaic substrate transmission line 10 can independently form a modular structure, thereby enabling rapid replacement of the mechanical structure of each photovoltaic substrate transmission line 10. Simultaneously, by using aviation connectors, the electrical modules of each photovoltaic substrate transmission line 10 can be plugged and played onto the main controller 50, enabling rapid replacement of the electrical modules of each photovoltaic substrate transmission line 10. This results in a high degree of modularity for each photovoltaic substrate transmission line 10, allowing for rapid replacement of one or more photovoltaic substrate transmission lines 10 without affecting the normal transmission and electrical performance of other photovoltaic substrate transmission lines 10. The aviation connectors can be common plug-and-play connectors found in existing technologies. In this embodiment, each photovoltaic substrate transmission line 10 adopts a standardized size to accommodate the transmission of photovoltaic substrates 20 with a length of 1.2m and a width of 2.4m.

[0086] Furthermore, a first sensor and a second sensor are respectively provided at the inlet and outlet ends of the frame 21 of each photovoltaic substrate transmission line 10. Both the first and second sensors are communicatively connected to the main controller 50. When both the first and second sensors detect signals and feed them back to the main controller 50, that is, when both the first and second sensors detect the photovoltaic substrate 20's arrival signal, the main controller 50 adjusts the transmission of the photovoltaic substrate 20 by each conveying roller 22 in the photovoltaic substrate transmission line 10, so that the photovoltaic substrate 20 is in a complete stop position on the photovoltaic substrate transmission line 10. Both the first and second sensors can be photoelectric start / stop sensors.

[0087] Specifically, such as Figure 8 As shown, since each photovoltaic substrate transmission line 10 is equipped with a driving component 4, the driving independence of each photovoltaic substrate transmission line 10 is relatively good, ensuring that the driving speed regulation of each photovoltaic substrate transmission line 10 to the photovoltaic substrate 20 on it does not interfere with each other, and further ensuring a high degree of modularity of each photovoltaic substrate transmission line 10. Specifically, the aforementioned main controller 50 is connected to the first driving component 41 in the driving component 4.

[0088] Currently, the transmission rate of the photovoltaic substrate by the first driving component of two adjacent photovoltaic substrate transmission lines is not dynamically synchronized. That is, there is a deviation in the driving transmission rate of the photovoltaic substrate by the first driving component of two adjacent photovoltaic substrate transmission lines. This can easily lead to deviation, collision, or stacking of the photovoltaic substrate between the two adjacent photovoltaic substrate transmission lines. As a result, the driving coordination between the two adjacent photovoltaic substrate transmission lines is poor, and the transmission accuracy and coordination of each photovoltaic substrate on each photovoltaic substrate transmission line cannot be guaranteed.

[0089] To solve the above problems, such as Figure 8 and Figure 9 As shown, a transition roller 51 is rotatably connected to the inlet end of the frame 21. An encoder 52 is mounted on the transition roller 51 and is communicatively connected to the main controller 50. When the rollers 222 on the previous photovoltaic substrate transmission line 10 transmit the photovoltaic substrate 20 to the transition roller 51, the encoder 52 on the transition roller 51 can dynamically capture the transmission rate of the photovoltaic substrate 20 and feed it back to the main controller 50. This allows the main controller 50 to control the output rate of the first drive unit 41 of the next photovoltaic substrate transmission line 10, ensuring that the output rate of the first drive unit 41 matches the transmission rate of the photovoltaic substrate 20 dynamically captured by the encoder 52. This enables the main controller 50 to coordinately adjust the transmission rates of two adjacent photovoltaic substrate transmission lines 10 to be the same. Specifically, the first drive unit 41 supports a speed adjustment range of 0 to 20 m / min, allowing the entire photovoltaic substrate transmission line 10 to adapt to various transmission rate requirements.

[0090] Compared with the prior art, the transmission device in this embodiment adds a transition roller 51 and an encoder 52 between the conveying rollers 22 in two adjacent photovoltaic substrate transmission lines 10. The encoder 52 and the main controller 50 dynamically coordinate the first drive unit 41 in each modularly configured photovoltaic substrate transmission line 10 to achieve online dynamic compensation of the output transmission rate of the first drive unit 41, so as to ensure that the transmission rate of each photovoltaic substrate transmission line 10 to the photovoltaic substrate 20 is consistent. This avoids the photovoltaic substrate 20 from deviating, colliding or stacking between two adjacent photovoltaic substrate transmission lines 10 due to inconsistent transmission rates, thereby ensuring good driving coordination between two adjacent photovoltaic substrate transmission lines 10 to the photovoltaic substrate 20, and thus ensuring the transmission accuracy and automatic coordination of the photovoltaic substrate 20 on each photovoltaic substrate transmission line 10.

[0091] Specifically, such as Figure 9As shown, the structure of the transition roller 51 is basically the same as that of the conveying roller 22 described above. The difference is that the transition roller 51 is driven to rotate by the conveying roller 22 in the previous photovoltaic substrate transmission line 10, so that the photovoltaic substrate 20 in the previous photovoltaic substrate transmission line 10 can be transferred to the conveying roller 22 in the next photovoltaic substrate transmission line 10 through the transition roller 51.

[0092] Specifically, the main controller 50 uses the transition roller 51 and encoder 52 to dynamically feedback the transmission rate of the previous photovoltaic substrate transmission line 10 to the photovoltaic substrate 20, and adjusts the output speed of the first drive unit 41 in the next photovoltaic substrate transmission line 10 in real time according to the dynamic compensation algorithm, thereby ensuring the synchronous transmission of the photovoltaic substrate 20 between two adjacent photovoltaic substrate transmission lines 10. The encoder 52 can adopt a common encoder structure in the prior art.

[0093] Furthermore, through the coordinated control between the encoder 52 and the main controller 50, emergency transmission for photovoltaic substrate 20 can be achieved. That is, when the previous photovoltaic substrate transmission line 10 fails due to an unexpected situation, the main controller 50 receives the feedback signal from the encoder 52 and automatically adjusts to reduce the transmission rate of the next photovoltaic substrate transmission line 10. In other words, the reduced-speed photovoltaic substrate transmission line 10 can provide a buffer function, and the faulty photovoltaic substrate transmission line 10 can be quickly replaced directly through the aforementioned aviation plug, thereby ensuring the transmission effect of each photovoltaic substrate transmission line 10 to the photovoltaic substrate 20. Then, the specific fault of the replaced photovoltaic substrate transmission line 10 can be eliminated offline.

[0094] By adopting the above-mentioned emergency transmission for photovoltaic substrate 20, on the one hand, the normal transportation of photovoltaic substrate 20 to each photovoltaic substrate transmission line 10 will not be delayed, so as to ensure the transmission accuracy and automatic coordination of photovoltaic substrate 20 on each photovoltaic substrate transmission line 10; on the other hand, by using the method of troubleshooting the specific faults of the replaced photovoltaic substrate transmission line 10 offline, time can be saved and online transmission time can be avoided, thereby improving the transmission efficiency of photovoltaic modules.

[0095] In this embodiment, the transmission device enables rapid replacement of the mechanical structure of each photovoltaic substrate transmission line 10 by making each photovoltaic substrate transmission line 10 independently modular. At the same time, the electrical modules of each photovoltaic substrate transmission line 10 can be plugged and played onto the main controller 50 through aviation plugs, thereby enabling rapid replacement of the electrical modules of each photovoltaic substrate transmission line 10. As a result, the modularity of each photovoltaic substrate transmission line 10 is high, enabling rapid replacement of one or more photovoltaic substrate transmission lines 10.

[0096] In this embodiment, the transmission device dynamically coordinates the first drive unit 41 in each modularly configured photovoltaic substrate transmission line 10 through the encoder 52 and the main controller 50, thereby realizing online dynamic compensation of the output transmission rate of the first drive unit 41. This avoids the photovoltaic substrate 20 from deviating, colliding, or stacking between two adjacent photovoltaic substrate transmission lines 10 due to inconsistent transmission rates, thus ensuring good driving coordination between two adjacent photovoltaic substrate transmission lines 10 for the photovoltaic substrate 20.

[0097] In this embodiment, the transmission device receives feedback signals from the encoder 52 through the main controller 50 and automatically adjusts to reduce the transmission rate of the next photovoltaic substrate transmission line 10. This allows the slowed-down photovoltaic substrate transmission line 10 to provide a buffering function. Then, the faulty photovoltaic substrate transmission line 10 can be quickly replaced directly through the aforementioned aviation plug. This ensures the transmission effect of each photovoltaic substrate transmission line 10 on the photovoltaic substrate 20. The specific faults of the replaced photovoltaic substrate transmission line 10 are then eliminated offline. The entire process of replacing the photovoltaic substrate transmission line 10 is simple, convenient, time-saving, and labor-saving, and does not affect the driving coordination of each photovoltaic substrate transmission line 10 on the photovoltaic substrate 20.
