Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell technology, and in particular to a welding strip supply device and a cell welding equipment. Background Technology

[0002] Solar cell modules are the core component of a solar photovoltaic system. Their function is to convert sunlight into electrical energy, outputting direct current (DC) which is then stored in a battery. Specifically, under sunlight, solar cell modules generate an electromotive force (EMF). These modules are connected in series and parallel to form a solar cell array, ensuring the array voltage meets the system's input voltage requirements. A charge / discharge controller then charges the battery, storing the electrical energy converted from sunlight.

[0003] In the production process of crystalline silicon solar modules, cell welding equipment connects multiple cells into a string using tin-plated copper strips (welding strips), achieving series welding between cells. A welding strip supply device provides welding strips to the cell welding equipment. Since the drive mechanism of the welding supply device is directly connected to the welding strip unwinding component, the drive mechanism controls the corresponding welding strip unwinding component to unwind the strip.

[0004] As the demand for solar cell modules increases, the production efficiency requirements for cell welding equipment are becoming higher and higher. The number of grid lines in the cells is increasing accordingly, as is the number of unwinding components required for the welding ribbon. This leads to an increase in the structural volume of the welding ribbon supply device and the floor space required for the cell welding equipment, which is not conducive to the expansion of the scale of cell welding equipment.

Figure 3 This is a top view of the welding strip supply device provided in an embodiment of this utility model.

Figure 5 This is the second structural schematic diagram of the welding strip supply frame provided in this embodiment of the utility model. Figure 6 yes Figure 4 The image shows a side view of the welding strip supply frame.

[0049] See Figures 1 to 6This utility model provides a welding strip supply device, which includes a mobile platform 10 and multiple rows of welding strip supply frames 20. The multiple rows of welding strip supply frames 20 can be arranged at intervals along the length of the mobile platform 10 according to actual usage needs. The multiple rows of welding strip supply frames 20 can be set to an odd number of rows, such as 5 rows, 7 rows, etc.; or they can be set to an even number of rows, such as 4 rows, 6 rows, 8 rows, etc. In actual use, the size of the mobile platform 10 is determined according to the installation space, and then the number of welding strip supply frames 20 is determined according to the size of the mobile platform 10.

[0050] Each row of welding strip supply frame 20 includes two opposing support members 21 and multiple rows of welding strip supply units 22, which are spaced apart along the height direction of the support members 21. Each row of welding strip supply units 22 includes a support shaft 221 and at least one welding strip supply module 222. To improve support stability, two support shafts 221 are provided in parallel, with each support shaft 221 located between the two opposing support members 21. The support shafts 221 are connected to each support member 21, and at least one welding strip supply module 222 is provided on the support shaft 221. That is, at least one welding strip supply module 222 can be provided on the support shaft 221, or two, three, or four welding strip supply modules 222 can be provided as needed.

[0051] It is understood that the welding strip supply device provided in this embodiment of the present invention, by arranging multiple rows of welding strip supply racks 20 at intervals on the moving platform 10, is equivalent to densely arranging multiple rows of welding strip supply racks 20 on the moving platform 10, which can significantly increase the number of welding strip supply racks 20 per unit area; each row of welding strip supply racks 20 includes two oppositely arranged support members 21 and multiple rows of welding strip supply units 22, the multiple rows of welding strip supply units 22 being arranged at intervals along the height direction of the support members 21, and similarly densely arranging multiple rows of welding strip supply units 22 on the moving platform 10. The number of solder strip supply units 22 per unit area can be significantly increased on the support member 21. Each row of solder strip supply units 22 includes a support shaft 221 and at least one solder strip supply module 222. The support shaft 221 is located between two oppositely arranged support members 21 and is connected to the support members 21 respectively. At least one solder strip supply module 222 is provided on the support shaft 221. Alternatively, the solder strip supply modules 222 can be densely arranged on the support shaft 221 according to actual use, which can significantly increase the number of solder strip supply modules 222 per unit area.

[0052] Because this invention features a dense arrangement from multiple directions, it can increase the number of welding strip supply modules 222 per unit area, meeting the requirements for improved production efficiency in battery cell welding equipment. Simultaneously, it can reduce the structural volume of the welding strip supply device, saving space in the battery cell welding equipment and facilitating increased production capacity. A reasonable arrangement ensures smooth welding strip supply and reduces the risk of entanglement.

[0053] Figure 7 This is a schematic diagram of the structure of the welding strip supply module in the welding strip supply device provided in this embodiment of the utility model.

[0054] See Figure 7 In some embodiments of this utility model, each welding strip supply module 222 includes a welding strip unwinding component 2221, a driving component 2222, a mounting bracket 2223, and a movable bracket 2224.

[0055] Both the mounting bracket 2223 and the movable bracket 2224 are sleeved on the support shaft 221. The welding strip unwinding component 2221 is located between the mounting bracket 2223 and the movable bracket 2224, and is connected to both the mounting bracket 2223 and the movable bracket 2224 respectively. That is, one end of the welding strip unwinding component 2221 is located on the mounting bracket 2223, and the other end is located on the movable bracket 2224. The driving component 2222 is located on the mounting bracket 2223.

[0056] Figure 8 This is a schematic diagram of the structure of the welding strip supply unit in the welding strip supply device provided in this embodiment of the utility model.

[0057] See Figure 8 In some embodiments of this utility model, the driving component 2222 includes a driving component 2222-1 and a transmission component; the driving component 2222-1 is fixedly installed on the mounting bracket 2223 by bolts or other structures, and the driving component 2222-1 and the welding strip unwinding component 2221 are arranged side by side; the transmission component is connected to the driving component 2222-1 and the welding strip unwinding component 2221 respectively.

[0058] Furthermore, the transmission component includes a transmission belt 2222-2, a driven pulley 2222-3, and a driving pulley 2222-4; the driven pulley 2222-3 is fixedly connected to the welding strip unwinding component 2221, the driving pulley 2222-4 is fixedly connected to the output shaft of the drive component 2222-1, and the transmission belt 2222-2 is wound around the driven pulley 2222-3 and the driving pulley 2222-4.

[0059] Essentially, to save installation space in the welding strip supply device, the original drive component 2222-1, which was directly connected to the welding strip unwinding component 2221 via a coupling, is replaced by a transmission component that indirectly transmits the power of the drive component 2222-1 to the welding strip unwinding component 2221, thereby driving the welding strip unwinding component 2221 to unwind. The transmission belt 2222-2 can be a synchronous belt, and both the driven pulley 2222-3 and the driving pulley 2222-4 can be synchronous pulleys. The transmission belt 2222-2 is wound around the driving pulley 2222-4 and the driven pulley 2222-3. When the drive component 2222-1 drives the driving pulley 2222-4 to rotate, the frictional pulley causes the driven pulley 2222-3 to rotate synchronously, thus causing the driven pulley 2222-3 to drive the welding strip unwinding component 2221 to rotate and unwind.

[0060] Compared to the direct connection between the drive component 2222-1 and the strip unwinding component 2221 via a coupling, this utility model allows the drive component 2222-1 (such as a motor) and the strip unwinding component 2221 (roller) to transmit power effectively even when they are not on the same axis or even not completely parallel, through the transmission belt 2222-2. That is, the drive component 2222-1 can be placed at a certain distance from the roller or arranged at an angle, which can increase the freedom of layout and facilitate the design of a compact structure.

[0061] In addition, the transmission belt 2222-2 can adjust the transmission by changing the tension. During installation or maintenance, even in a small space, the corresponding adjustments can be easily made to ensure that the power transmission meets the optimal condition.

[0062] In addition, in some embodiments of this utility model, the transmission component can also be replaced by gear transmission instead of belt transmission, that is, indirect drive is achieved by the meshing of gear pairs (not shown in the figure). For example, the gear pair includes a driving gear and a driven gear, which mesh with each other. The driving gear is connected to the driving component 2222-1, and the driven gear is connected to the welding strip unwinding component 2221. When the driving gear is driven to rotate by a power source, the driven gear is forced to rotate accordingly through the tooth profile action between the gears, realizing the transfer of energy, so as to drive the welding strip unwinding component 2221 to rotate synchronously to achieve unwinding.

[0063] Figure 9 This is a top view of the welding strip supply unit in the welding strip supply device provided in this embodiment of the utility model. Figure 10 yes Figure 9 A cross-sectional view along line AA.

[0064] See Figure 9 and Figure 10In some embodiments of this utility model, the strip unwinding component 2221 includes a strip reel 2221-1, a drive shaft 2221-2 and a driven shaft 2221-3. The drive shaft 2221-2 is rotatably mounted on the mounting bracket 2223 via bearings and other transmission components, and the driven shaft 2221-3 is rotatably mounted on the movable bracket 2224 via bearings and other components.

[0065] The drive shaft 2221-2 is inserted into one end of the welding strip reel 2221-1. The drive shaft 2221-2 and the welding strip reel 2221-1 are in a driving engagement, meaning that the drive shaft 2221-2 can be connected to the welding strip reel 2221-1 via a spline. The drive shaft 2221-2 can also be inserted into the welding strip reel 2221-1 via a pin arranged parallel to it. The axis of the pin is not coaxial with the rotation center of the welding strip reel 2221-1. The drive shaft 2221-2 passes through the mounting bracket 2223 and extends to one end, and is fixedly connected to the driven wheel 2222-3 of the transmission component via a key or the like. The driven shaft 2221-3 is inserted into the other end of the welding strip reel 2221-1.

[0066] When the driving component 2222-1 drives the driving wheel 2222-4 to rotate, the driven wheel 2222-3 is driven to rotate synchronously by the pulling force of friction. This causes the driven wheel 2222-3 to drive the driving shaft 2221-2 to rotate, and the driving shaft 2221-2 drives the welding strip reel 2221-1 to rotate around the driven shaft 2221-3, thus realizing the unwinding function.

[0067] Continue reading Figure 7 , Figure 9 and Figure 10 In some embodiments of the utility model, the movable bracket 2224 includes a bracket body 2224-1, a limiting member 2224-2, and a locking member 2224-3.

[0068] The frame body 2224-1 is tractably mounted on the support shaft 221 and can move along the length of the support shaft 221. That is, the frame body 2224-1 can be mounted on the support shaft 221 by means of a sliding bearing or a sliding sleeve. The sliding bearing (also called a sliding bearing or bushing bearing) allows the support shaft 221 to rotate inside it, while it can also slide on the external frame body 2224-1 along the axial direction of the support shaft 221.

[0069] The limiting member 2224-2 is sleeved on the support shaft 221 and can move freely along the axial direction of the support shaft 221. The limiting member 2224-2 abuts against the frame body 2224-1. A limiting hole is provided on the limiting member 2224-2. The locking member 2224-3 is inserted into the limiting hole, which is suitable for restricting the limiting member 2224-2 to the support shaft 221, thereby restricting the position of the frame body 2224-1.

[0070] Among them, the locking component 2224-3 can be a hand-tightening bolt, which is set on the limiting component 2224-2 and is used to fix the limiting component 2224-2 to the support shaft 221.

[0071] When it is necessary to replace the welding strip reel 2221-1, loosen the hand-tightening bolt, slide the limiting member 2224-2 along the support shaft 221 away from the frame body 2224-1, then pull the frame body 2224-1 and the driven shaft 2221-3 on the frame body 2224-1 out of the welding strip reel 2221-1. Then remove the welding strip reel 2221-1 that has released all the welding strip, replace it with a new welding strip reel 2221-1, and move the frame body 2224-1 close to the welding strip reel 2221-1 so that the driven shaft 2221-3 is inserted into the welding strip reel 2221-1. Then adjust the limiting member 2224-2 to a suitable position so that the limiting member 2224-2 abuts against one side of the frame body 2224-1, and tighten the hand-tightening bolt to prevent the frame body 2224-1 from moving on the support shaft 221.

[0072] Continue reading Figure 7 In some embodiments of the utility model, the mounting bracket 2223 includes a mounting body 2223-1, a first mounting part 2223-2 and a second mounting part 2223-3. The first mounting part 2223-2 extends laterally along the mounting body 2223-1, and the second mounting part 2223-3 extends longitudinally along the mounting body 2223-1.

[0073] In the same strip supply frame 20, the mounting bodies 2223-1 of the mounting brackets 2223 in each strip supply module 222 are connected end to end in sequence; the driving component 2222-1 of the driving component 2222 is located in the first mounting part 2223-2, and the strip unwinding component 2221 is located in the second mounting part 2223-3.

[0074] Since the mounting bracket 2223 remains fixed, it is equivalent to the mounting bracket 2223 in the welding strip supply module 222 of a row being integrally formed, which facilitates the positioning and installation of the welding strip supply module 222 in a row and can improve installation efficiency.

[0075] Continue reading Figure 5 In some embodiments of the utility model, each welding strip supply module 222 further includes a guide component 2225. The guide component 2225 is disposed on the side of the mounting bracket 2223 opposite to the drive component 2222-1 of the drive component 2222. The guide component 2225 is used to guide the welding strip reversal of the corresponding welding strip unwinding component 2221.

[0076] In the same row of solder strip supply modules 222, each guide component 2225 is staggered to avoid interference between the solder strips released by different solder strip supply modules 222.

[0077] In addition, the support shaft 221 is rotatably mounted on the support member 21 via transmission components such as bearings, so that when the welding strip comes into contact with the support shaft 221, the friction between the two can be reduced, thereby avoiding affecting the supply of welding strip.

[0078] Figure 11 This is a partial structural schematic diagram of the mobile platform provided in an embodiment of the present utility model.

[0079] Continue reading Figure 1 and Figure 2 And see also Figure 11 In some embodiments of the utility model, the mobile platform 10 includes a mounting base 11, a mobile body 12, and a drive component 13.

[0080] The movable body 12 is located above the mounting base 11 and is arranged parallel to the mounting base 11. Both the mounting base 11 and the movable body 12 are rectangular plates, and the mounting base 11 and the movable body 12 are arranged horizontally. The movable body 12 provides support and installation space for the multi-row welding strip supply frame 20.

[0081] A guide member 14 is provided on either the mounting base 11 or the moving body 12, and a mating member 15 that slides with the guide member 14 is provided on the other of the mounting base 11 and the moving body 12. That is, the guide member 14, such as a guide rail, can be installed on the mounting base 11 using countersunk bolts or similar structures, and the mating member 15, such as a slider, can be installed on the moving body 12 using countersunk bolts or similar structures; alternatively, the mating member 15 can be installed on the mounting base 11 using countersunk bolts or similar structures, and the guide member 14 can be installed on the moving body 12 using countersunk bolts or similar structures.

[0082] The drive assembly 13 is mounted on the mounting base 11 and connected to the moving body 12. The drive assembly 13 drives the moving body 12 to move between the working position and the changing position, facilitating the replacement of the solder strip reel 2221-1, shortening the replacement time of the solder strip reel 2221-1, and improving production efficiency. The working position is the position of the moving body 12 when each solder strip reel 2221-1 is normally releasing solder strip, and the changing position is the position of the moving body 12 when replacing the solder strip reel 2221-1.

[0083] The drive assembly 13 includes a motor and a lead screw and nut assembly, both of which are fixedly mounted on the mounting base 11. The lead screw and nut assembly is connected to the output shaft of the motor. The lead screw and nut of the lead screw and nut assembly are fixedly connected to the moving body 12 by bolts, and the lead screw of the lead screw and nut assembly is arranged parallel to the guide rail.

[0084] When the motor drives the lead screw and nut pair to move, the guide 14 and the mating part 15 cooperate to convert the rotational motion of the lead screw and nut pair into linear reciprocating motion, thereby enabling the moving body 12 to change position relative to the mounting base 11, which facilitates the installation and replacement of the welding strip 2221-1.

[0085] It should be noted that the motor can be directly connected to the lead screw of the lead screw and nut pair through a coupling or the like, or it can be indirectly connected to the lead screw of the lead screw and nut pair through a transmission component. The specific setting is determined based on the space between the mounting base 11 and the moving body 12.

[0086] Multiple rows of welding strip supply racks 20 are spaced apart on the surface of the moving body 12. The drive components 2222 in every two welding strip supply racks 20 are arranged opposite each other, and a replacement space 23 is formed between every two welding strip supply racks 20. The drive component 2222-1 in the drive component 2222 is located on the other side of the welding strip supply rack 20 away from the replacement space 23.

[0087] In some embodiments of this utility model, the welding strip supply module 222 further includes a displacement sensor 2226, which is detachably connected to the mounting bracket 2223. The displacement sensor 2226 is arranged opposite to the welding strip reel 2221-1 in the welding strip unwinding component 2221. The displacement sensor 2226 is used to detect the length of the welding strip wound on the welding strip reel 2221-1.

[0088] The displacement sensor 2226 can be connected to the mounting bracket 2223 via a fixing rod parallel to the axis of the strip unwinding component 2221. A threaded hole can be made in the mounting bracket 2223 for the fixing rod to be threaded onto it. Alternatively, the displacement sensor 2226 can be connected to the fixing rod via a hand-tightening bolt. When the bolt is loosened, the displacement sensor 2226 can slide along the length of the fixing rod, thereby changing the position of the displacement sensor 2226 and aligning it with the strip reel 2221-1.

[0089] It should be noted that multiple guide rollers (not shown in the figure) are also provided on the mobile platform 10. The number of guide rollers is the same as the number of welding strip reels 2221-1, and a guide roller is provided under each welding strip reel 2221-1. The outer circumferential surface of the guide roller is provided with two guide grooves, and each guide groove is used to guide the welding strip output from the welding strip reel 2221-1.

[0090] When the welding strip supply device provided in this embodiment of the utility model is working, the driving component 2222-1 drives the welding strip reel 2221-1 to rotate through the transmission belt 2222-2, thereby releasing the welding strip on the welding strip reel 2221-1. By controlling the rotation speed of the driving component 2222-1, the output speed of the welding strip can be precisely controlled. After the output welding strip passes around the guide shaft of the guide component 2225, it moves toward the guide roller to enter the next process for use.

[0091] This utility model also provides a battery cell welding device, including a main body and a welding strip supply device as described above, wherein the welding strip supply device is used to supply welding strip to the main body of the device. The battery cell welding device can be understood as a string welder capable of simultaneously outputting at least two battery strings. Because this battery cell welding device includes the aforementioned welding strip supply device, it possesses all the advantages described above.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
