Description

Technical Field

[0001] This invention relates to the field of jumper wire welding technology, and in particular to a jumper wire welding machine and welding method. Background Technology

[0002] A solar panel is a device that converts solar energy into electrical energy using the photovoltaic effect. Also known as a photovoltaic solar panel, it typically consists of multiple strings of photovoltaic cells that absorb sunlight and convert it into direct current (DC) electricity. These panels can be installed on rooftops, the ground, or other suitable areas of buildings to generate or supply electricity. As an important means of clean energy generation, photovoltaic solar panels are receiving increasing attention and widespread application. To improve the welding efficiency of busbars and jumpers on the short sides of the battery strings, automatic jumper welding machines are now widely used. These machines connect battery strings in parallel using jumpers, which specifically consist of insulating film and busbars.

[0003] Before welding the battery string, the glass plate and the battery string need to be aligned to ensure that the overlapping part of the busbar and jumper wire on the short side of the battery string is aligned with the welding end of the welding part. However, in the existing jumper wire welding machine, the welding part is in a fixed position along the long side of the glass plate. Due to installation errors or long-term use, the position of the battery string will deviate after the alignment mechanism is aligned. This causes the overlapping part of the busbar and jumper wire on the short side of the battery string to not be aligned with the welding end of the welding part. In other words, the welding position of the overlapping part will be deviated, and the jumper wire welding strength will be lower. Summary of the Invention

[0004] This invention provides a jumper welding machine and welding method, which can ensure the efficiency of jumper connection and ensure that the overlapping part of the bus bar at the short side of the battery string and the bus bar inside the jumper is in the welding position, thus ensuring the accuracy of jumper welding position and welding strength.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A jumper wire welding machine, comprising: The frame has a horizontally positioned correction welding area. The feeding mechanism is used to transport the glass plate carrying the battery string to the correction welding area along the short side of the glass plate. The jumper wire preparation mechanism is located above the feeding mechanism and on the long side of the glass plate in the correction welding area. It is used to place jumpers of the corresponding battery string length along the long side of the glass plate. The correction mechanism, including a long-side correction section and a short-side correction section, corrects the deviation of the glass plate at the correction welding area; A jumper feeding mechanism, located above the jumper preparation mechanism, is used to transport and place the jumpers from the jumper preparation mechanism onto the battery string on the glass plate that has been corrected in the correction welding area. The battery string welding mechanism includes two sets of welding sections for welding jumpers on both short sides of the battery string; The short-side correction section includes a short-side correction drive and two sets of short-side correction components. The two sets of short-side correction components are distributed at intervals along the long side of the glass plate. The short-side correction drive is connected to both sets of short-side correction components so that the two sets of short-side correction components are close to or far away from the center of the correction welding area along the long side of the glass plate. The two sets of welding parts are correspondingly connected to the two sets of short side correction components, so that under the drive of the short side correction drive, they move along the long side of the glass plate to the two short sides of the glass plate, respectively, and weld the busbars at the two short sides of the battery string on the glass plate to the jumpers at the two short sides.

[0006] Preferably, the jumper is formed by stacking two insulating films and two busbars along the long side of the glass plate onto the battery string.

The two baffles are arranged at intervals in the vertical direction, the counterweight wheel is located between the two baffles and is slidably disposed on the feeding rack in the vertical direction, and the flow bar is arranged around the outside of the counterweight wheel from below; The two detection elements are located between the two baffles, and the two detection elements are respectively a certain distance away from the two baffles in the vertical direction, and respectively detect the movement of the counterweight wheel to the upper and lower baffles; When the busbar preparation line pulls the busbar, the counterweight wheel slides upward through the busbar. The detection component above detects the counterweight wheel, and the busbar feeding part feeds the busbar until the counterweight wheel abuts against the baffle above. When the busbar preparation line stops pulling the busbar, the counterweight wheel slides downwards, the detection component below detects the counterweight wheel, the busbar feeding section stops feeding the busbar, and the counterweight wheel abuts against the baffle below.

[0009] Preferably, the jumper feeding mechanism includes a first moving part, a second moving part, a conveying part, and a heating part; The first movable part is disposed on the frame, and the second movable part is disposed at the movable end of the first movable part. The movable end of the second movable part is connected to the mounting part and moves back and forth in the horizontal direction along with the movable end of the first movable part. The transport unit is used to transport the busbar and the insulating film. The transport unit is located on the mounting unit and moves back and forth in the vertical direction with the moving end of the second moving unit. The first moving unit and the second moving unit work together to move the transport unit through the mounting unit to transport the busbar and the insulating film onto the battery string. The heating element is located at the moving end of the second moving part and moves back and forth in the vertical direction with the moving end of the second moving part to heat the busbar and insulating film placed on the battery string, and fix the battery string, busbar and insulating film into a whole.

[0010] Preferably, the conveying unit includes a first adsorption component and a second adsorption component arranged along the long side of the glass plate; The first adsorption component and the second adsorption component are arranged side by side, and the distance between them is adapted to the distance between the insulating film and the busbar after the jumper material preparation mechanism is completed, so that the first adsorption component and the second adsorption component can adsorb the insulating film and the busbar respectively and simultaneously.

[0012] Preferably, the short-side correction assembly includes a correction mounting frame and a short-side correction sub-assembly disposed on the correction mounting frame; The welding section includes a welding assembly and a backing plate assembly, both of which are connected to the alignment mounting frame. The pad assembly includes a pad drive and a pad. The pad drive is fixedly mounted on the correction mounting frame. The drive end of the pad drive is connected to the pad so that the pad is inserted between the glass plate and the end where the short side of the battery string is located before the jumper wire is welded to the welding head in the welding assembly.

[0013] Preferably, there are two jumper wire preparation mechanisms, which are distributed along the short side of the glass plate on both sides of the glass plate at the correction welding area. The jumper feeding mechanism is provided in two parts, and the two jumper feeding mechanisms respectively transport the insulating film and busbar at the two jumper material preparation mechanisms.

[0014] A welding method for the above-mentioned jumper wire welding machine includes: The glass plate carrying the battery strings is transported to the correction welding area by the feeding mechanism. The jumper material preparation mechanism prepares insulating film and busbars simultaneously, and places a set of insulating film and a set of busbars side by side along the long side of the glass plate. The set of insulating film includes two insulating films, and the set of busbars includes two busbars with one end bent. The alignment mechanism uses long-side and short-side alignment sections to align the glass plate and battery string. The transfer end of the jumper feeding mechanism simultaneously transports a set of insulating film and a set of busbars to the battery string, and stacks the busbars and insulating film on the battery string; The heating unit inside the jumper feeding mechanism heats the stacked busbars and insulating film, fixing the busbars, insulating film and battery string into a whole; Driven by the short-side correction drive, the two sets of welding parts continue to move along the long side of the glass plate to above the two short sides of the battery string, and perform jumper welding on the two short sides of the battery string. After the jumper wire welding is completed, the welded part is moved away from the battery string under the drive of the short side correction drive.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the coordinated use of the feeding mechanism, jumper preparation mechanism, correction mechanism, jumper feeding mechanism and battery string welding mechanism, the battery string carrying the glass plate is moved to the correction and welding area. The jumper preparation, correction, feeding and welding of the battery string in the correction and welding area are carried out, realizing the automated welding of the jumper and improving the welding efficiency.

[0016] 2. The two sets of welding parts can move along the long side of the glass plate under the drive of the short side correction drive. Even if the glass plate deviates in position along its long side after correction, the two sets of welding parts can still move along the long side of the glass plate to the short side of the battery string. This ensures that the overlapping part of the busbar at the short side of the battery string and the end of the busbar in the jumper are aligned with the welding end of the welding part, guaranteeing the accuracy of the welding position and the welding strength of the busbar at the short side of the battery string and the busbar in the jumper at the short side.

[0017] 3. The welding part moves simultaneously with the short side correction assembly under the drive of the short side correction drive, so that the welding part and the short side correction assembly share the same drive. Only the two need to be connected together, which reduces the complexity of the installation position and drive of the short side correction assembly and the welding part on the jumper welding machine.

Detailed Implementation

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] This invention provides a jumper welding machine, such as... Figures 1-3As shown, the system specifically includes a frame 1 and a feeding mechanism 2, a jumper wire preparation mechanism 3, a jumper wire feeding mechanism 4, a correction mechanism 5, and a battery string welding mechanism 6 mounted on the frame 1. A correction welding area 11 is horizontally arranged on the frame 1. The feeding mechanism 2 transports the glass plate 7 carrying the battery string to the correction welding area 11 along the short side of the glass plate 7. The jumper wire preparation mechanism 3 is located above the feeding mechanism 2 and is used to place jumpers of corresponding battery string lengths along the long side of the glass plate 7. The correction mechanism 5 is used to correct the alignment of the glass plate 7. Specifically, the correction mechanism 5 includes a long side correction part 52 and a short side correction part 51. The correction welding area 11 corrects the alignment of the long side of the glass plate 7. The oblique portion 52 and the short-side correction portion 51 are arranged to form a misalignment. The long-side correction portion 52 is used to contact the long side of the glass plate 7 in the correction welding area 11, so that the position of the long side of the glass plate 7 is moved and corrected. The short-side correction portion 51 is used to contact the short side of the glass plate 7 in the correction welding area 11, so that the position of the short side of the glass plate 7 is moved and corrected, so that the entire glass plate is finally moved to the corrected position, completing the correction of the glass plate 7. It should be noted that the battery string is placed on the glass plate 7, and its position relative to the glass plate 7 will not change during transportation. The glass plate 7 serves as a transport carrier and is transported to the correction welding area. Within the welding area 11, the position of the glass plate 7 may shift. Therefore, it is only necessary to correct the position of the glass plate 7 using the correction mechanism 5, and the position of the battery string on the glass plate will also be corrected accordingly. The jumper wire loading mechanism 4 is located above the jumper wire preparation mechanism 3 and is used to transport and place the jumper wires from the jumper wire preparation mechanism 3 onto the battery string on the glass plate that has been corrected in the correction welding area 11. The placed jumper wires are ready for welding. It should be noted that since the jumper wire preparation mechanism 3 is located on one side of the long side of the glass plate 7 in the correction welding area 11 and the prepared jumper wires are set along the long side of the glass plate 7, the transport end of the jumper wire loading mechanism 4 does not need to be rotated. The operation is automated, requiring only horizontal and vertical transport to move the jumper wires onto the battery string on the glass plate 7 within the alignment and welding area 11. The battery string welding mechanism includes two welding sections, which weld the jumper wires at the two short sides of the battery string respectively. In summary, through the cooperation of the feeding mechanism 2, jumper wire preparation mechanism 3, jumper wire feeding mechanism 4, alignment mechanism 5, and battery string welding mechanism 6, the preparation, alignment, feeding, and welding of jumper wires in the alignment and welding area are achieved, realizing automated jumper wire welding. Compared to manual preparation, feeding, and welding, this greatly improves the welding efficiency between the busbars at the short sides of the battery string and the ends of the busbars within the jumper wires. It should be noted that the size of the battery string is adapted to the glass plate 7, and the short side direction of the glass plate 7 mentioned above is also the short side direction of the battery string, and the long side direction of the glass plate 7 is also the long side direction of the battery string.

[0025] It should be noted that in this embodiment, the jumper wire is arranged along the long side of the glass plate 7, and the jumper wire is divided into two sections. The ends of the two jumper wires that are close to each other are located in the middle of the battery string, and are subsequently connected to the electrical box set in the middle of the battery string. In the welding process, only the ends of the two jumper wires that are far apart need to be welded. The welding part in the battery string welding mechanism 6 is set into two groups. After the glass plate 7 is corrected, the two groups of welding parts can be located at the ends of the two short sides of the glass plate 7 respectively during welding. The two groups of welding parts weld the busbars and jumper wires at the two short sides of the battery string respectively, thus completing the welding of the battery string.

[0026] Existing jumper welding machines require a correction mechanism 5 to correct the alignment of the battery string on the glass plate between jumper welding operations. This ensures that the overlapping portion of the busbar on the short side of the battery string and the jumper is aligned with the welding end of the welding part. However, the welding part on existing jumper welding machines is generally in a fixed position. Due to installation errors or long-term use, the long side correction part 52 and the short side correction part 51 in the correction mechanism 5 may deviate from their positions after correction. This causes the overlapping portion of the busbar on the short side of the battery string to not be aligned with the welding end of the welding part, resulting in a deviation in the welding position of the overlapping portion and a decrease in jumper welding strength. Furthermore, the fixed welding part is only suitable for battery strings of the same size. If it is necessary to weld battery strings of a different size, the position of the welding part needs to be readjusted so that it is aligned with the short side of the battery string. This facilitates welding the busbar on the short side of the battery string to the end of the busbar inside the jumper. However, adjusting the position of the welding part is cumbersome, time-consuming, and labor-intensive.

[0027] To solve the above problems, such as Figures 27-28As shown, the short-side correction section 51 includes a short-side correction drive 511 and two sets of short-side correction components 512. The two sets of short-side correction components 512 are spaced apart along the long side of the glass plate 7. The short-side correction drive 511 is connected to both sets of short-side correction components 512, so that the two sets of short-side correction components 512 move closer to or further away from the center of the correction welding area 11 along the long side of the glass plate 7, and the two sets of welding parts are respectively connected to the two sets of short-side correction sections 51. Thus, the two sets of welding parts can move along the long side of the glass plate 7 together with the short-side correction section 51 under the drive of the short-side correction drive 511. Even if the position of the correction mechanism along the long side of the glass plate deviates from the original predetermined position after the glass plate and battery string are corrected due to installation errors and long-term use, the welding end of the welding part 4 can still move along the long side of the glass plate. Driven by the short-side correction drive 11, it can still move along the long side of the glass plate to the short side of the battery string, so that the overlapping part of the busbar and jumper at the short side of the battery string is aligned with the welding end of the welding part 4, ensuring the accuracy of the welding position and the welding strength of the overlapping part of the busbar and jumper at the short side of the battery string. Moreover, the two sets of welding parts that can move along the long side of the glass plate 7 can be adjusted to adapt to the jumper welding of battery strings of different specifications by adjusting the distance between the two sets of welding parts. It should also be noted that the welding part moves simultaneously with the short-side correction assembly 512 under the drive of the short-side correction drive 511, so that the welding part and the short-side correction assembly 512 share the same drive. It is only necessary to connect the two together, which reduces the complexity of the installation position and drive of the short-side correction assembly 512 and the welding part on the jumper welding machine.

[0028] In this embodiment, the jumper is formed by stacking two busbars and two insulating films on the battery string. The jumper material preparation mechanism is used to prepare two busbars and two insulating films at the same time. The jumper material feeding mechanism stacks the two insulating films and two busbars onto the battery string, that is, the two insulating films are placed on the battery string along the long side, and the two busbars are placed on the two insulating films along the long side of the battery string to form the jumper to be welded. The two sets of welding parts are used to weld the ends of the busbars at the two short sides of the battery string to the ends of the two busbars in the jumper, thus completing the welding of the two ends of the jumper to the two short side busbars of the battery string.

[0029] Specifically, the jumper preparation mechanism 3 needs to prepare insulation film and busbars simultaneously, such as Figures 4-11As shown, the jumper cable preparation mechanism 3 specifically includes a feeding section 31, a preparation rack 32, an insulating film preparation line 33, and a busbar preparation line 34. The feeding section 31 is used to store and retrieve insulating films and busbars. The insulating film preparation line 33 and the busbar preparation line 34 are mounted on the preparation rack 32. The insulating film preparation line 33 is used to retrieve insulating films from the feeding section 31 and prepare them (retrieve insulating films of the corresponding length). The busbar preparation line 34 is used to retrieve busbars from the feeding section 31 and prepare them (retrieve busbars of the corresponding length). The insulating film preparation line 33 and the busbar preparation line 34 are arranged along the glass plate... The insulating film and busbars are arranged side-by-side along their long sides, ensuring that the prepared insulating film and busbars are also arranged side-by-side. The parallel arrangement of the insulating film and busbars on the same preparation rack 32 facilitates the simultaneous handling by the jumper feeding mechanism 4, improving the handling efficiency of the feeding mechanism. Furthermore, when the feeding mechanism stacks the insulating film and busbars on the battery string, because they are parallel, the jumper feeding mechanism 4 only needs to make minor adjustments to the insulating film and busbars in the horizontal and vertical directions to achieve stacking, without requiring excessive adjustments to their relative positions, thus reducing the structural complexity of the feeding mechanism. It is important to note that the lengths of the insulating film and busbars in the jumper must be consistent. The parallel insulating film preparation line 33 and busbar preparation line 34 work in conjunction with the feeding section 31 to simultaneously prepare the insulating film and busbars, improving preparation efficiency and allowing for direct comparison to ensure the consistency of the lengths of the prepared insulating film and busbars.

[0030] Specifically, such as Figures 5-7As shown, the insulating film preparation line 33 includes an insulating film placement section 331, an insulating film holding section 332, an insulating film cutting section 333, and an insulating film traction section 334, all mounted on a preparation rack 32. The insulating film placement section 331 includes an insulating film mounting frame and an insulating film placement plate, both arranged along the length of the preparation rack 32. The insulating film placement plate is mounted above the insulating film mounting frame, which is mounted on the preparation rack 32. The insulating film placement plate is used to place the prepared insulating film for transport by the feeding mechanism. The insulating film holding section 332 is located at the inlet end of the insulating film preparation line 33 and is used to hold the insulating film to prevent it from detaching from the insulating film preparation line 33. The traction ends of the insulating film holding section 332, the insulating film cutting section 333, and the insulating film traction section 334 are arranged along... The material preparation rack 32 is arranged sequentially along its length. The insulating film traction unit 334 is used to traction the insulating film along the length of the material preparation rack 32. When the required length is reached, the insulating film cutting unit 333 cuts the insulating film. It should be noted that during the traction process, the insulating film holding unit 332 does not hold the insulating film, so that the insulating film can be pulled stably. After the insulating film traction unit 334 pulls the insulating film to the required length, the insulating film holding unit 332 holds the insulating film so that the insulating film cutting unit 333 can cut the insulating film. When the traction end of the insulating film traction unit 334 returns to the insulating film cutting unit 333, the insulating film holding unit 332 no longer holds the insulating film, and the traction end of the insulating film traction unit 334 continues to traction the insulating film for the next time.

[0031] Specifically, such as Figures 8-9As shown, the busbar preparation line 34 includes a busbar placement section 341, a busbar holding section 342, a busbar cutting section 343, a busbar traction section 344, and a busbar bending section 345, all mounted on a preparation rack 32. The busbar placement section 341 is arranged along the length of the preparation rack 32 and has a notch. The busbar bending section 345 is located at the notch. In this embodiment, the busbar placement sections 341 on both sides of the notch each hold a busbar under the traction of the busbar traction section 344 and the cutting action of the busbar cutting section 343. The busbar bending section 345 at the notch can bend the adjacent ends of the two busbars. The busbar holding section 342 is located at the feed end of the busbar preparation line 34 and is used to hold the busbar to prevent it from detaching from the busbar preparation line 34. The busbar cutting section 343 and the busbar traction section 344 are sequentially arranged along the length of the material preparation rack 32. The busbar traction section 344 is used to traction the busbar along the length of the material preparation rack 32. When the required length is reached, the busbar cutting section 343 cuts the busbar. It should be noted that during the traction process, the busbar holding section 342 does not hold the busbar, so that the busbar can be stably tractioned. After the busbar traction section 344 has traction the busbar to the required length, the busbar holding section 342 holds the busbar so that the busbar cutting section 343 can cut the busbar. When the traction end of the busbar traction section 344 returns to the busbar cutting section 343, the busbar holding section 342 no longer holds the busbar, and the traction end of the busbar traction section 344 continues to traction the busbar for the next time.

[0032] Specifically, to facilitate stable traction of the insulating film cutting end by the insulating film traction unit 334, and to facilitate stable traction of the busbar cutting end by the busbar traction unit 344, both the insulating film cutting unit 333 and the busbar cutting unit 343 include a cutting component 3331 and a cutting drive component 3332. The cutting component 3331 is slidably disposed on the material preparation rack 32 along the length direction of the material preparation rack 32. The cutting drive component 3332 can be a linear drive component 421, which can be a cylinder. The cutting drive component 3332 is connected to the cutting component 3331. The cutting component 3331 can be driven to slide back and forth along the length of the material preparation rack 32. Specifically, after the cutting component 3331 cuts the material (insulating film or busbar) once, after the traction part is completed and reset, before the material is pulled again, the cutting component 3331 moves away from the traction part along the length of the material preparation rack 32, so that more of the cut material end is exposed, so that the traction end of the traction part can stably clamp and pull the material end. Then, the cutting component 3331 is reset to its original position under the drive of the cutting drive component 3332 to cut.

[0033] Specifically, the insulating film pressing part 332 and the busbar pressing part 342 have the same structure, both including a pressing cylinder and a pressing plate. The pressing cylinder pushes the pressing plate downward and presses the insulating film or busbar on the material preparation rack 32 onto the abutment block, thus completing the pressing of the insulating film or busbar. Specifically, the insulating film traction part 334 and the busbar traction part 344 have the same structure, both including a traction assembly 3341 and a clamping member 3342. The clamping member 3342 is arranged on the material preparation rack 32 along the length direction of the material preparation rack 32. The movable end of 41 is connected to the clamping member 3342 to cooperate with the clamping member 3342 to clamp the insulating film or busbar, and to move the insulating film or busbar along the length direction of the material rack 32, pulling the insulating film or busbar to the required length. Specifically, the traction component 3341 can be a synchronous belt component, and the clamping member 3342 can be a combination of a cylinder and a clamping plate. The synchronous belt of the synchronous belt component is connected to a traction mounting plate, and the cylinder is located on the traction mounting plate. The cylinder drives the clamping plate to approach the traction mounting plate, thereby clamping the insulating film or busbar.

[0034] Specifically, the busbar placement section 341 includes a busbar mounting frame 3411, two busbar placement plates 3412 slidably disposed above the busbar mounting frame 3411, and a busbar placement plate driving member 3413 disposed on the busbar mounting frame 3411. The two busbar placement plates 3412 are spaced apart to form a notch. There are two corresponding busbar placement plate driving members 3413. The two busbar placement plate driving members 3413 drive the two busbar placement plates 3412 to move closer or further away along the length direction of the material rack 32, which can reduce or increase the notch, thereby adjusting the distance between the ends of the two busbars to fit the size on the photovoltaic panel. After adjustment, there is no need to adjust the position during material loading or battery string adjustment. It should be noted that the bending end of the busbar bending section 345 will also be adjusted accordingly to fit the adjusted notch size, so that the bending length remains unchanged, but the distance between the two busbar bending sections 345 will change accordingly. Specifically, the busbar placement plate drive 3413 can be a combination of a cylinder and a push plate. A sliding block is connected between the busbar mounting bracket 3411 and the busbar placement plate 3412. The sliding block is fixedly connected to the push plate. The cylinder pushes the sliding block relative to the busbar mounting bracket 3411 through a push rod, so that the busbar placement plate 3412 slides.

[0035] Specifically, such as Figure 9As shown, the busbar bending section 345 includes a bending holding member 3451 and a bending member 3452. Two sets of bending holding members 3451 are provided, respectively connected to the busbar placement plates 3412 on both sides of the notch. Each bending holding member 3451 specifically includes a cylinder, a bending mounting bracket, and a rotating pressure plate. The bending mounting bracket is mounted on the busbar placement plate 3412, and the cylinder is mounted on the bending mounting bracket. One end of the rotating pressure plate is rotatably connected to the cylinder, and the other end is rotatably connected to the bending mounting bracket, thereby allowing the cylinder's output shaft to move vertically, enabling it to... The rotating pressure plate rotates, and the end of the rotating pressure plate can press the busbar onto the busbar placement plate 3412 so that the bending component 3452 can be bent. Correspondingly, the bending component 3452 includes a cylinder and two bending blocks. The cylinder is mounted on the busbar mounting bracket 3411, and the two bending blocks are mounted on the output end of the cylinder. The output shaft of the cylinder moves vertically so that the bending blocks push the busbar from bottom to top, causing the end of the busbar to bend. Of course, the distance between the two bending blocks can be adjusted by bolts to adapt to the size after the notch adjustment.

[0036] Specifically, the insulating film preparation line 33 also includes an insulating film fixing part 335, which is installed on the insulating film placement rack. Specifically, it is a combination of a cylinder and a pressure plate, which presses the prepared insulating film onto the insulating film placement rack. The busbar preparation line 34 also includes a busbar fixing part 346, which is installed on the insulating film placement rack. Specifically, it is a combination of a cylinder and a pressure plate, which presses the prepared busbar onto the busbar placement plate 3412, waiting for the feeding mechanism to transport it.

[0037] Specifically, such as Figure 5 and Figure 7 As shown, the insulating film placement plate has multiple sets of insulating film adjustment holes along its length. Each set includes two rows of insulating film width adjustment holes 3311. The distance between corresponding two width adjustment holes along the length of the insulating film placement plate is different in the insulating film preparation direction. In this embodiment, the distance between corresponding two width adjustment holes along the width direction of the insulating film placement plate gradually increases in the two rows of insulating film width adjustment holes 3311 along the insulating film preparation direction. Screws are installed in the corresponding two width adjustment holes to limit the width of the insulating film. This is achieved by adjusting the screws 651... The installation position is adapted to accommodate insulating films of different widths. When the insulating film is placed on the insulating film placement plate, the insulating film can be limited by screws. Similarly, the busbar placement plate 3412 is provided with multiple busbar adjustment hole groups along its length. The busbar adjustment hole groups include two rows of busbar width adjustment holes 3414. In this embodiment, along the busbar preparation direction, the distance between the two corresponding width adjustment holes gradually increases along the width direction of the busbar placement plate 3412. The width of the busbar is limited by installing screws in the corresponding two width adjustment holes.

[0038] Specifically, such as Figures 10-11 As shown, the feeding section 31 includes a feeding rack 311 and an insulating film feeding section 31, an insulating film detection component 315, a busbar feeding section 31, and a busbar detection component 319 disposed on the feeding rack 311. The insulating film feeding section 31 includes an insulating film sleeve 312, an insulating film guide wheel assembly 314, and an insulating film drive component 313. The busbar feeding section 31 includes a busbar sleeve 316, a busbar guide wheel assembly 318, and a busbar drive component 317. The insulating film sleeve 312 is wound with insulating film. The insulating film drive component 313 is connected to the insulating film sleeve 312 to drive the insulating film sleeve 312 to rotate and feed the insulating film, and cooperates with the insulating film guide wheel assembly 314 to guide the insulating film. The busbar sleeve 316 is wound with busbars. The busbar drive component 317 is connected to the busbar sleeve 316 to drive the busbar sleeve 316 to rotate and feed the insulating film. The busbar is fed and cooperates with the busbar guide wheel assembly 318 to guide the busbar. Both the insulating film guide wheel assembly 314 and the busbar guide wheel assembly 318 include multiple guide wheels to guide the discharge direction of the insulating film according to actual needs. The insulating film detection component 315 cooperates with the insulating film drive component 313 and the insulating film traction part 334 in the insulating film preparation line 33 to rotate the insulating film drive component 313 and cause the insulating film sleeve 312 to feed the insulating film when the insulating film preparation line 33 is transporting the insulating film. The busbar detection component 319 cooperates with the busbar drive component 317 and the busbar traction part 344 in the busbar preparation line 34 to rotate the busbar drive component 317 and cause the busbar sleeve 316 to feed the busbar when the busbar preparation line 34 is transporting the busbar. Specifically, both the insulating film drive unit 313 and the busbar drive unit 317 are motors.

[0039] Specifically, the insulating film detection element 315 and the busbar detection element 319 have the same structure and operate in the same manner. In this embodiment, as... Figure 11 As shown, the busbar detection component 319 includes a counterweight wheel 3191, a detection component 3192, and a baffle 3193. Two baffles 3193 are provided, which are spaced apart vertically. The counterweight wheel 3191 is located between the two baffles 3193 and is slidably mounted on the feeding rack 311 vertically. The feeding rack 311 is specifically provided with a first slide rail vertically. The counterweight wheel 3191 is slidably mounted on the first slide rail via a second sliding frame. The busbar is wrapped around the outside of the counterweight wheel 3191 from below. Two detection components 3192 are provided, which are respectively located at the two baffles 3193 to detect the movement of the counterweight wheel 3191 to the baffle 3193.

[0040] Specifically, when the busbar preparation line 34 is not pulling the busbar, the second sliding frame connected to the counterweight wheel 3191 abuts against the lower second abutment plate. At this time, the detection element 3192 at the second abutment plate detects that the counterweight wheel 3191 is located at the second abutment plate. The busbar drive element 317 does not work, and the busbar sleeve 316 does not rotate to release material. When the busbar preparation line 34 pulls the busbar, the busbar can drive the counterweight wheel 3191 to slide upward to the upper baffle 3193. The second sliding frame abuts against the upper baffle 3193. Before this, because there is a certain distance between the upper baffle 3193 and the upper detection element 3192, the detection element 3192 will first detect that the counterweight wheel 3191 is close to the upper baffle 3193. At this time, the busbar drive element 317 starts to rotate and discharge material until the second sliding frame abuts against the upper baffle 3193. The counterweight wheel 3191 will no longer rise and will guide the busbar normally. It should be noted that during the time that the upper detection element 3192 detects the counterweight wheel 3191 abutting against the second sliding frame and the upper baffle 3193, The busbar remains in a relaxed state, preventing the insulation film from stretching due to the busbar drive unit 317 and the busbar traction unit 344 in the busbar preparation line 34 not working simultaneously. This provides a traction buffer, ensuring that the busbar does not have any stretching after preparation, and the initial traction process is smoother. When the busbar traction unit 344 in the busbar preparation line 34 stops traction, the counterweight wheel 3191 slides downwards to the lower baffle 3193. Because the lower baffle 3193 and the lower detector... The measuring component 3192 is at a certain distance. The lower measuring component 3192 will first detect that the counterweight wheel 3191 is close to the lower baffle 3193. At this time, the busbar drive component 317 stops rotating, and the busbar stops feeding. However, the busbar drive component 317 will still have inertia, and the busbar sleeve 316 will continue to rotate until the second sliding frame abuts against the lower baffle 3193. The counterweight wheel 3191 will no longer descend. During this period, the counterweight wheel 3191 will also continue to contact the busbar until the inertial rotation of the busbar sleeve 316 stops. Ideally, the busbar will still abut against the counterweight wheel 3191 to ensure stable guidance of the busbar. However, in actual use, there may be too much excess busbar that is released and will be lower than the counterweight wheel 3191, not abutting against the counterweight wheel 3191. But under the drive of the busbar traction part 344, it can quickly abut against the counterweight wheel 3191 and continue to stably guide the busbar. It should be noted that the detection component 3192 can be a photoelectric sensor, and the weight of the counterweight wheel 3191 will not cause the busbar to be elongated.

[0041] Specifically, such as Figures 12-18As shown, the jumper feeding mechanism 4 includes a first moving mechanism and a conveying mechanism. The first moving mechanism specifically includes a first moving part 41, and the conveying mechanism specifically includes a second moving part 42, a conveying part, and a heating part 46. The first moving part 41 is mounted on the frame 1 and can reciprocate to convey materials in the horizontal direction. The second moving part 42 can convey materials in the vertical direction. The moving end of the second moving part 42 is connected to an installation part 43. The conveying part is used to convey the busbar and the insulating film. The second moving part 42 is connected to the moving end of the first moving part 41, and the conveying part is mounted on the installation part 43. Thus, the installation part 43 and the conveying part located on the installation part 43 can reciprocate in the vertical and horizontal directions to convey the busbar and the insulating film at the jumper feeding mechanism 3 to the battery string, which facilitates the feeding of the busbar and the insulating film to the battery string and their stacking to form a jumper. It should be noted that when the handling unit moves the busbars and insulating films, the insulating film should be placed on the battery string first, and then the busbars should be placed on the insulating film accordingly. This achieves the purpose of placing the jumper formed by stacking the busbars and insulating films on the battery string. Moreover, a jumper on the battery string consists of two insulating films and two busbars, with the two busbars placed on the two insulating films respectively.

[0042] Because the busbar and insulating film are placed separately in the jumper preparation mechanism 3, the transport unit places them sequentially onto the battery string. In the jumpers placed on the battery string, the busbar and insulating film are not connected; the insulating film is pressed between the busbar and the battery string. The positions of the insulating film and the busbar are easily changed by external vibrations. To prevent changes in the positions of the busbar and insulating film before welding the busbar to the short side of the battery string, which could alter the relative positions of the busbar and the short side of the battery string and thus change the welding position of the jumper, [further details are needed]. Figure 13 As shown, the jumper feeding mechanism 4 also includes a heating part 46. The heating part 46 can heat the busbar, insulating film and battery string placed on the battery string and fix the three into a whole. Specifically, the heating part 46 is installed on the mounting part 43, so that under the drive of the first moving part 41 and the second moving part 42, the heating part 46 can move with the mounting part 43 in the vertical and horizontal directions. The heating part 46 can approach and heat the busbar, insulating film and battery string, so that they are connected to form a whole. The relative positions between the busbar, insulating film and battery string will not change before welding, ensuring the accuracy of the welding position between the busbar in the jumper and the busbar at the short side of the battery string, and further ensuring the wiring position between the two busbar bends and the battery box set in the middle of the battery string.

[0043] It should be noted that the insulating film is a combination of EVA and insulating film, which can melt under heating and bond and fix with the busbar and battery string, realizing the connection and fixation between the busbar and the insulating film, and between the insulating film and the battery string, so that the busbar, insulating film and battery string are fixed into a whole.

[0044] Specifically, the transport unit includes a first adsorption component 44 and a second adsorption component 45 arranged along the long side of the glass plate 7. The first adsorption component 44 and the second adsorption component 45 are arranged side by side, and the distance between them is adapted to the distance between the insulating film and the busbar after the jumper material preparation mechanism 3 has been prepared, so that the first adsorption component 44 and the second adsorption component 45 can adsorb the insulating film and the busbar respectively and simultaneously, and transport the insulating film and the busbar at the same time, thereby improving the transport efficiency. During transport, the insulating film is first placed on the battery string, and then the busbar is stacked on the insulating film.

[0045] Specifically, in this embodiment, such as Figure 15 and Figure 17 As shown, the first adsorption component 44 and the second adsorption component 45 respectively include multiple first suction cup components 441 and multiple second suction cup components 451, and the multiple first suction cup components 441 and multiple second suction cup components 451 are distributed along the length direction of the insulating film. Thus, the multiple first suction cup components 441 can adsorb the insulating film at multiple points along the long side of the glass plate 7 to stably transport the insulating film, and the multiple second suction cup components 451 can adsorb the busbar at multiple points along the length direction of the busbar to stably transport the busbar. Specifically, the first suction cup components 441 and the second suction cup components 451 include suction cups and pipe supports connected to the suction cups, and the pipe supports are fixed on the mounting part 43. It should be noted that the first suction cup components 441 can also adsorb the busbar, and correspondingly, the second suction cup components 451 adsorb the insulating film. The adsorption correspondence between the first suction cup components 441 and the second suction cup components 451 can be replaced according to usage requirements.

[0046] Specifically, such as Figure 15 and Figure 17As shown, the heating section 46 includes multiple heating elements distributed along the length of the insulating film. The heating section 46 heats the insulating film and fixes the battery string, insulating film, and busbar into a single unit. The multiple heating elements within the heating section 46 can heat the insulating film at multiple points along the long side of the glass plate 7, creating multiple connection points between the battery string, insulating film, and busbar. This ensures the stability of the connection between the battery string, insulating film, and busbar. Furthermore, it is not necessary to completely cover the insulating film along the long side of the glass plate 7 for heating; multiple heating points are sufficient to create multiple connection points between the battery string, insulating film, and busbar. This avoids the heating section 46 becoming too large and covering too much area along the long side of the glass plate 7, which would affect the installation and adsorption of the adsorption assembly. It also ensures the compactness of the overall structure after the heating elements and suction cup assembly within the heating section 46 at the installation section 43 are installed.

[0047] Specifically, such as Figure 16 and Figure 18 As shown, the heating element includes a mounting bracket 461, a hot air pipe 462, and a heating drive component 463. The heating drive component 463 is mounted on the mounting bracket 461, which is connected to the mounting part 43. The outlet of the hot air pipe 462 faces downward and is connected to the drive end of the heating drive component 463. The heating drive component 463 can be a cylinder. The output rod of the cylinder faces downward and can drive the hot air pipe 462 to move back and forth in the vertical direction. Thus, the hot air pipe 462 can move closer to or further away from the insulating film and busbar already placed on the battery string in the vertical direction.

[0048] The hot air inside the hot air duct 462 also needs time to heat up. To ensure the heating efficiency of the hot air duct 462 on the insulating film and busbars on the battery string, the temperature of the hot air ejected from the hot air duct 462 must reach the temperature of the heat-melting insulating film when it approaches the insulating film and busbars. The heat-melting operation can then be performed when the hot air duct 462 reaches the heat-melting position. Therefore, a heating drive component 463 is provided. The heating drive component 463 can drive the hot air duct 462 to move vertically. Before the hot air reaches the temperature of the heat-melting insulating film, the hot air duct 462 can rise to a certain distance from the insulating film. This ensures that the temperature of the hot air ejected from the hot air duct 462 can continuously increase, while also preventing the continuous ejection of hot air from affecting the handling of the insulating film. Furthermore, both the hot air duct 462 and the suction cup assembly are installed on... On the mounting part 43, to prevent the hot air ejected from the hot air pipe 462 from prematurely melting the insulating film during the transportation process, after the suction cup assembly transports the insulating film and busbar onto the battery string, the second moving part 42 moves the heating element closer to the battery string, and the heating drive 463 further moves the hot air pipe 462 closer to the insulating film. The hot air ejected from the hot air pipe 462 can immediately melt part of the insulating film, so that the battery string, insulating film and busbar are glued and fixed into a whole, ensuring the heating and fixing efficiency of the three. After the hot air pipe 462 is heated, the heating drive 463 makes the hot air pipe 462 rise to its original position, waiting for the next heating. It should be noted that once the hot air pipe 462 is closed and then reopened, the air needs to be reheated. In order to ensure the temperature of the hot air, the hot air pipe 462 needs to continuously eject hot air.

[0049] Specifically, such as Figure 17 As shown, the mounting part 43 includes a first mounting slide rail 431 and a second mounting slide rail 432 arranged along the length of the insulating film. Two second mounting slide rails 432 are provided, each located at one end of the first mounting slide rail 431. The first mounting slide rail 431 is fixedly connected to the moving end of the second moving part 42, and their positions are relatively fixed. The two second mounting slide rails 432 can slide relative to the first mounting slide rail 431 along its length according to usage requirements. That is, when the two second mounting slide rails 432 are in their fixed positions, they are respectively connected to the first mounting slide rail 431 via connecting plates 433. If the position of the second mounting slide rail 432 needs to be adjusted, the connecting plate 433 between the first mounting slide rail 431 and the second mounting slide rail 432 is removed, allowing the second mounting slide rail 432 to slide to the desired position. Then, the first mounting slide rail 431 and the second mounting slide rail 432 are fixed by the connecting plate 433. It should be noted that, for structural symmetry and ease of adjustment, the first mounting slide rail 431 is located between the two second mounting slide rails 432, and the two second mounting slide rails 432 can also be adjusted simultaneously, so that both ends of the first mounting slide rail 431 are indirectly extended at the same time.

[0050] Correspondingly, multiple first suction cup components 441 within the first adsorption component 44 are partially disposed on the first mounting slide rail 431 and partially on the second mounting slide rail 432. Similarly, multiple second suction cup components 451 within the second adsorption component 45 are partially disposed on the first mounting slide rail 431 and partially on the second mounting slide rail 432. This allows the position of the second mounting slide rail 432 to slide relative to the first mounting slide rail 431, changing the length of both the multiple first suction cup components 441 and the multiple second suction cup components 451 along the long side of the glass plate 7. This adapts to insulating films and busbars of different lengths. Correspondingly, multiple heating elements are partially disposed on the first mounting slide rail 431 and partially on the second mounting slide rail 432. After the position of the second mounting slide rail 432 slides relative to the first mounting slide rail 431, the length of the heating elements along the long side of the glass plate 7 changes to accommodate insulating films and busbars of different lengths, heating them and forming connection points at suitable locations. Specifically, the first suction cup assembly 441 and the second suction cup assembly 451 are located on both sides of the slide rail (first mounting slide rail 431 or second mounting slide rail 432) along its width.

[0051] Furthermore, such as Figures 16-18As shown, based on the fact that the second mounting slide rail 432 can be adjusted in position relative to the first mounting slide rail 431, both the first mounting slide rail 431 and the second mounting slide rail 432 are provided with grooves along their lengths. The pipe supports in each first suction cup assembly 441 and second suction cup assembly 451 can be detachably installed on the grooves. By disassembling, the user can change the position of the pipe supports of the first suction cup assembly 441 and the second suction cup assembly 451 relative to the grooves, thereby adjusting the distance between two adjacent first suction cup assemblies 441 and two adjacent second suction cup assemblies 451 to further accommodate the required length of the insulating film and manifold, so that the multiple first suction cup assemblies 441 in the first suction assembly 44 can move along the long side of the glass plate 7. The evenly distributed and stable adsorption of the insulating film ensures that the multiple second suction cup assemblies 451 within the second adsorption assembly 45 can evenly distribute and stably adsorb the busbar along its length. This prevents the insulating film and busbar from sagging or becoming loose during transport due to improper adjustment of the suction cup assemblies, further guaranteeing the stability and tightness of the insulating film and busbar during transport. Correspondingly, the fixing bracket 461 within each heating element can also be detachably installed on the slide rail. By disassembling, the user can change the position of the fixing bracket 461 within the heating element relative to the slide rail, thereby adjusting the distance between the hot air pipes 462 within the two heating elements to further adapt to the heating points of the insulating film and busbar of the required length, ensuring a stable connection between the battery string, the insulating film, and the busbar. A sliding block is provided within the slide rail. The pipe support within the suction cup assembly and the fixing bracket 461 within the heating element can be bolted to the sliding block, and the bolts are tightened to fix the sliding block relative to the first mounting slide rail 431 or the second mounting slide rail 432. Specifically, the first mounting slide rail 431 has first grooves 4311 on both sides of its width direction. The first suction cup assembly 441 and the second suction cup assembly 451 on the first mounting slide rail 431 are respectively installed on the first grooves 4311 on both sides. The second mounting slide rail 432 has second grooves 4321 on both sides of its width direction. The first suction cup assembly 441 and the second suction cup assembly 451 on the second mounting slide rail 432 are respectively installed on the second grooves 4321 on both sides. The first mounting slide rail 431 has a third groove 4312 on its side. The heating element on the first mounting slide rail 431 is located in the third groove 4312. The second mounting slide rail 432 has a fourth groove 4322 on its upper end face. The heating element on the second mounting slide rail 432 is located in the fourth groove 4322.

[0052] Specifically, such as Figure 14As shown, the first moving part 41 includes a rotating member 411, a drive shaft 412, a synchronous belt group 413, and a first connecting frame 414. There are two synchronous belt groups 413, which are distributed along the length of the insulating film and are arranged parallel to each other. The drive shaft 412 is connected to the output shaft of the rotating member 411 and is connected to the drive pulleys in the two synchronous belt groups 413. The two ends of the connecting frame are respectively connected to the synchronous belts in the two synchronous belt groups 413. The connecting frame is fixedly connected to the second moving part 42, so that the rotating member 411 can drive the synchronous belts in the two synchronous belt groups 413 to move the connecting frame in the horizontal direction, thereby driving the second moving part 42 and the mounting part 43 to move in the horizontal direction. The rotating member 411 is specifically a motor.

[0053] Specifically, such as Figure 15 As shown, the second moving part 42 includes a linear drive 421 and a second connecting frame 422. The linear drive 421 is mounted on a mounting frame, which is mounted on the frame 1 of the jumper welding machine. The second connecting frame 422 is connected to the moving end of the linear drive 421 and is connected to the mounting part 43. The linear drive 421 can drive the second connecting frame 422 to move in the vertical direction, thereby driving the mounting part 43 to move in the vertical direction. The linear drive 421 can be a combination of a rotary motor and a lead screw or a cylinder.

[0054] Specifically, such as Figures 19-22As shown, the short-side correction assembly 512 includes a correction mounting bracket 5121 and a short-side correction sub-assembly 5122 disposed on the correction mounting bracket 5121. The short-side correction sub-assembly 5122 includes a short-side drive component 51221 and a short-side correction component 51222. The short-side drive component 51221 can be a cylinder, and its output shaft is arranged along the long side of the glass plate 7. The output shaft of the short-side drive component 51221 is connected to the short-side correction component 51222 for transmission, thereby driving the short-side correction component 51222 to move closer to or away from the correction along the long side of the glass plate 7. The center of the welding area 11 is positioned close to or away from the end of the short side of the glass plate 7. When it approaches the end of the short side of the glass plate 7, it causes the end of the short side of the glass plate 7 to move for correction. Furthermore, multiple short side correction sub-assemblies 5122 are provided, and these multiple short side correction sub-assemblies 5122 are distributed along the short side direction of the glass plate 7. Thus, multiple short side correction components 51222 can work together on the end face of the end of the short side of the glass plate 7, making it easier for the glass plate 7 to move and adjust its position along the long side direction, and making the end of the short side of the glass plate 7 move more stably. The welding part is connected to the correction mounting bracket 5121, and the short side correction drive component 511 specifically includes a synchronous belt assembly. Two correction mounting brackets 5121 are connected to the synchronous belts on both sides of the synchronous belt assembly, so that the short side correction drive component 511 can drive the welding part and the short side correction sub-assemblies 5122 on it to move along the long side direction of the glass plate 7 through the two correction mounting brackets 5121.

[0055] Specifically, such as Figure 21 As shown, the short-side correction assembly 512 also includes a short-side correction component height drive assembly 5123. The short-side correction component height drive assembly 5123 includes a short-side correction component height drive component 51231 and a short-side correction component drive frame 51232. The short-side correction component height drive component 51231 is mounted on the correction mounting frame 5121. Specifically, the short-side correction component height drive component 51231 is configured as a cylinder, with its output shaft arranged vertically. The output shaft of the short-side correction component height drive component 51231 is connected to the short-side correction component drive frame 51232. The drive connection is used to move the short side correction drive frame vertically and adjust the height of the short side correction drive frame 51232. The short side drive component 51221 is fixedly installed on the short side correction drive frame 51232. The height of the short side drive component 51221 and the short side correction component 51222 can be adjusted according to the actual height of the glass plate 7. When correcting, the short side correction component 51222 can stably and fully contact the end face of the short side of the glass plate 7, ensuring the correction of the position of the short side of the glass plate 7.

[0056] Specifically, such as Figure 22As shown, the long-side correction section 52 includes a long-side correction drive 521 and a long-side correction assembly 522. The long-side correction assembly 522 includes a reciprocating transport member 221 and a long-side correction sub-assembly 5222 connected to the reciprocating transport member 221. The long-side correction sub-assembly 5222 includes long-side correction elements 52221. The long-side correction sub-assemblies 5222 are configured in two groups, that is, the long-side correction elements 52221 are configured in two groups. The two groups of long-side correction assemblies 522 and the two groups of long-side correction elements 52221 are distributed along the short side direction of the glass plate 7. The correction drive is driven to the reciprocating transport member 221 so that the long-side correction elements 52221 in the two groups of long-side correction assemblies 522 are driven to the reciprocating transport member 221. 2221 moves closer to or further away from the center of the correction welding area 11 along the short side direction of the glass plate 7. Two sets of long side correction components 52221 move closer to the center of the correction welding area 11 along the short side direction of the glass plate 7. During the approach process, the two sets of long side correction components 52221 can correspondingly contact the end faces of the two long sides of the glass plate 7. By pushing the two end faces of the glass plate 7, the ends of the two long sides of the glass plate 7 are moved and corrected. It should be noted that the short side correction component 51222 and the long side correction component 52221 need to move towards the center of the correction welding area 11 at the same time to limit and correct the long side direction and the short side direction of the glass plate 7 at the same time, so as to ensure the correction efficiency of the glass plate 7 and the battery string.

[0057] The long-side correction sub-assembly 5222 also includes a long-side correction height drive 52222, which can be a cylinder with its output shaft pointing vertically upwards. A long-side correction component 52221 is located on the output shaft of the long-side correction height drive 52222, allowing for height adjustment. Specifically, in this embodiment, the glass plate 7 needs to be transported to the correction welding area 11 along the short side direction of the glass plate 7 by an external feeding mechanism 2. Before the welding zone 11, the long side correction component 52221 moves downward to below the glass plate 7 under the drive of the long side correction height drive component 52222, so as not to interfere with the transportation of the glass plate 7 into the correction welding zone 11. After the glass plate 7 is transported to the correction welding zone 11, the long side correction component 52221 moves upward to the horizontal outer side of the long side of the glass plate 7 under the drive of the long side correction height drive component 52222, so as to cooperate with the short side correction component 51222 to correct the glass plate 7 located in the correction welding zone 11.

[0058] Furthermore, the long-side correction assembly 522 is configured as multiple sets, and the reciprocating transport components 221 within the long-side correction assembly 522 are all arranged along the short side direction of the glass plate 7. The multiple sets of reciprocating transport components 221 are distributed at intervals along the long side direction of the glass plate 7. This not only allows for multiple long-side correction components 52221 located at the long side of the glass plate 7, but also enables these multiple long-side correction components 52221 to work together on the end face of the end of the long side of the glass plate 7, making it easier for the glass plate 7 to move along the short side direction. By adjusting its position, the end of the glass plate 7 with the long side moves more stably and corrects its deviation. Moreover, in this embodiment, the glass plate 7 is transported to the deviation correction welding area 11 by the feeding mechanism 2 along the short side direction. The reciprocating moving part set along the short side direction of the glass plate 7 will not interfere with the position setting of the transport component in the feeding mechanism 2. It can also make the transport component in the feeding mechanism 2 set along the short side direction of the glass plate 7, so that the feeding mechanism 2 and the long side deviation correction component 522 on the jumper welding machine are in a compact position, which reduces the volume of the jumper welding machine to a certain extent. Specifically, in this embodiment, the reciprocating moving parts are arranged side by side along the short side of the glass plate 7. It should be noted that the two sets of long side correction sub-assemblies 5222 in the same long side correction assembly 522 are respectively connected to the synchronous belts on both sides of the synchronous belt group 413 through the long side connecting plate 433. Thus, under the drive of the synchronous belt, the two sets of long side correction sub-assemblies 5222 can move closer or further away along the short side of the glass plate 7. Moreover, the long side connecting plate 433 is slidably mounted on the frame 1 of the jumper welding machine along the short side of the glass plate 7 to ensure the stable sliding of the two sets of long side correction sub-assemblies 5222.

[0059] Specifically, both the long-side correction component 52221 and the short-side correction component 51222 are configured as correction wheels, which make the correction wheels roll contact with the end face of the glass plate 7, reducing the friction between them and making it easier to move the glass plate 7 and correct its alignment. In addition, the correction wheels are fitted with elastic sleeves on the outside, which are made of nylon and can buffer the small-amplitude collision force generated between the correction wheels and the end face of the glass plate 7, and are wear-resistant.

[0060] The existing glass plate 7 typically has an EVA film. The battery string is placed on the EVA film. After the busbars at the short side of the battery string are welded to the busbars inside the jumper wires at the short side, the battery string can be directly pressed onto the glass plate 7 through the EVA film during the subsequent lamination process. However, the welding head 613 in the welding section is located at the short side of the battery string during welding. The heat generated during welding can easily melt the EVA film between the short side end of the battery string and the glass plate 7, causing the EVA film at the short side end of the battery string to become incomplete. In the subsequent photovoltaic panel lamination process, this can lead to air bubbles between the short side end of the battery string and the glass plate 7, affecting the pressing quality of the battery string. To solve this problem, the welding section includes a welding assembly 61 and a pad assembly 62. The welding assembly 61 is used to weld the jumper wires. Both the welding assembly 61 and the pad assembly 62 are connected to the alignment installation. On the frame 5121, the pad assembly 62 specifically includes a pad drive 621 and a pad 622. The pad drive 621 is mounted on the alignment mounting frame 5121 and is connected to the pad 622, allowing the pad 622 to move closer to or further away from the battery string. Specifically, when welding is required, the pad 622 is inserted between the short end of the battery string and the EVA film on the glass plate 7. The pad 622 separates the glass plate 7 from the welding head 613 inside the pad assembly 62, preventing the heat radiated by the welding head 613 from melting the EVA film between the glass plate 7 and the battery string. This ensures the integrity of the EVA film between the short end of the battery string and the glass plate 7, guarantees the welding yield of the battery string, and further ensures that there are no air bubbles between the short end of the battery string and the glass plate 7 after the subsequent lamination process of the battery string, glass plate 7, and the EVA film between them. It should be noted that the pad 622 can be made of epoxy board for better durability.

[0061] Specifically, such as Figure 23 and Figure 24As shown, the pad drive 621 is mounted on the short side correction component drive frame 51232 within the short side correction component height drive assembly 5123, enabling the pad 622 and the pad drive 621 to move vertically. The pad drive 621 can be a cylinder with its output shaft horizontally positioned. The output shaft of the pad drive 621 is connected to the pad 622 via a transmission, causing the pad 622 to move linearly closer to and away from the glass plate 7, and allowing the pad 622 to be inserted between the glass plate 7 and the end where the short side of the battery string is located. This allows the pad assembly 62 and the short side correction component 51222 to share the same height drive component, resulting in a more compact structure and... The pad 622 and the pad drive 621 can move vertically, which can prevent the pad 622 from hitting the glass plate 7 when it is close to the battery string. The short side correction component height drive assembly 5123 first raises the pad 622 so that the pad 622 is higher than the glass plate 7. After the pad 622 is inserted between the end of the short side of the battery string and the glass plate 7, the height of the pad 622 is lowered so that the pad 622 contacts the glass plate 7. In this way, after the jumper wire is soldered, the distance that the end of the short side of the battery string descends can be shortened, avoiding the situation where the end of the short side of the battery string collides with the glass plate 7 and is damaged.

[0062] Specifically, such as Figure 23 As shown, multiple pads 621 and 622 are provided and are evenly distributed along the short side of the battery string. After the short side of the battery string is lifted by multiple adsorption components 633, multiple pads 622 can be inserted between the short side of the battery string and the glass plate 7, so that the short side of the battery string is still at the same height after being lifted, which makes it easier for the welding head 613 to weld the jumper wire more stably.

[0063] Specifically, such as Figure 25 As shown, the welding assembly 61 includes a welding drive 611, a welding mounting plate 612, and a welding head 613. The drive end of the welding drive 611 is connected to the welding mounting plate 612, enabling the welding mounting plate 612 to reciprocate in the vertical direction. The welding drive 611 can be a screw mechanism or a cylinder. The welding mounting plate 612 slides on the vertical correction mounting bracket 5121. The output shaft of the cylinder is downward and connected to the welding mounting plate 612. The welding head 613 is mounted on the welding mounting plate 612.

[0064] Among them, such as Figure 25As shown, the welding section also includes a lifting assembly 63, which is used to lift the end of the battery string where the short side is located, so that the pad 622 can be inserted between the end of the battery string where the short side is located and the glass plate 7. Specifically, the lifting assembly 63 includes a lifting drive 631, a lifting frame 632, and an adsorption member 633. The lifting frame 632 is located above the battery string, and the adsorption member 633 is installed on the lifting frame 632. The lifting end of the lifting drive 631 is connected to the lifting frame 632 so that the lifting frame 632 and the adsorption member 633 can move back and forth in the vertical direction. Before the jumper wire is welded, the lifting drive 631 first drives the lifting frame 632 and the adsorption member 633 downwards and closer. The battery string is attracted to the short side of the battery string by the suction member 633. The lifting drive member 631 drives the lifting frame 632 and the suction member 633 upward away from the battery string, so that the short side of the battery string rises, thereby forming an insertion space between the short side of the battery string and the glass plate 7. Then, the pad drive member 621 drives the pad 622 to approach and insert into the insertion space. Subsequently, the lifting drive member 631 drives the lifting frame 632 downward to place the short side of the battery string on the pad 622. The suction member 633 no longer attracts the short side of the battery string. The lifting drive member 631 drives the lifting frame 632 and the suction member 633 upward away from the battery string and back to their original position. Specifically, the lifting drive component 631 is configured as a cylinder, and the drive shaft 412 of the cylinder is set vertically downward. Multiple suction components 633 are provided, and multiple suction cups are evenly distributed along the short side of the battery string to stably lift and move the end of the short side of the battery string. The suction component 633 is configured as a suction cup connected to an external air passage.

[0065] Specifically, the lifting drive component 631 and the welding head 613 within the lifting assembly 63 are both connected to the welding mounting plate 612. Both can reciprocate vertically together with the welding mounting plate 612. The lifting assembly 63 does not need to be directly mounted on the correction mounting frame 5121, but is indirectly connected to the correction mounting frame 5121 through the welding mounting plate 612, which makes the overall structure more compact. Since both the welding head 613 and the adsorption component 633 need to be raised and lowered, the lifting assembly 63 connected to the welding mounting plate 612 can share the raising and lowering distance of the welding head 613. This reduces the vertical raising and lowering distance of the lifting frame 632 and the adsorption component 633 driven by the lifting drive component 631 during the entire welding process, shortens the time for forming the insertion space, and further shortens the overall welding time.

[0066] Furthermore, such as Figure 25 and Figure 26As shown, a welding head mounting bracket 614 is provided on the outer side of the welding head 613. The welding head 613 is connected to a welding head 613 connecting plate 433. The welding head 613 connecting plate 433 is slidably mounted on the welding head mounting bracket 614 in the vertical direction. The top and bottom of the welding head 613 connecting plate 433 are respectively provided with an elastic element 615 and a contact portion 616. The welding head 613 connecting plate 433 is located between the elastic element 615 and the contact portion 616. When the welding head 613 is not welding, the elastic element 615 is in a compressed state, so that the welding head 613 and the contact portion 616 are in a compressed state. 6. The welding head 613 is positioned to ensure stability. Specifically, driven by the welding drive unit 611, the welding head 613 descends and comes into contact with the jumper. Due to the obstruction of the pad 622, the elastic element 615 continues to compress. This further compression ensures a tight contact between the welding head 613, the busbar inside the jumper, and the busbar at the short side of the battery string. The elastic element 615 also prevents excessive descent of the welding head 613 due to installation errors, which could excessively compress the shortened end of the battery string or even damage it. To make the compression of the elastic element 615 more stable in the vertical direction, a guide rod 617 is connected to the upper end of the welding head 613 connecting plate 433. The upper end of the guide rod 617 passes through a guide hole at the top of the welding head mounting bracket 614. The elastic element 615 is a spring, sleeved on the outer periphery of the guide rod 617, allowing the elastic element 615 to compress stably along the guide rod 617.

[0067] Specifically, the welding mounting plate 612 is provided with an adjustment slide rail 64 along the short side of the battery string, and the welding head mounting bracket 614 is slidably mounted on the adjustment slide rail 64. Correspondingly, the welding mounting plate 612 is provided with an adjustment component 65, which is connected to the welding head mounting bracket 614. This allows the welding head mounting bracket 614 to move back and forth along the adjustment slide rail 64, thereby adjusting the position of the welding head mounting bracket 614 and the position of the welding head 613 to correspond to the position of the jumper wire on the battery string, ensuring the welding strength of the jumper wire. The adjustment component 65 includes an adjustment screw 651. Since the spacing and placement position of the two jumper wires on the battery string are basically not adjusted, the adjustment screw 651 can be set to manual operation. A handle 652 is provided at the end of the adjustment screw 651, and a mounting groove for the adjustment tool to be inserted is provided at the handle 652.

[0068] Specifically, such as Figure 29As shown, the feeding mechanism 2 includes multiple sets of transport synchronous belt assemblies 21 arranged side by side along the short side of the glass plate 7. The glass plate 7 containing the battery string is transported by the multiple sets of transport synchronous belt assemblies 21. Specifically, a support crossbeam 12 is also provided on the frame 1. The support crossbeam 12 is located in the correction welding area 11. Multiple universal balls 13 are arranged on the support crossbeam 12 along the short side of the glass plate 7. The multiple universal balls 13 arranged along the short side of the glass plate 7 provide a certain degree of support for the glass plate 7 in the correction welding area 11, and also make it easier for the glass plate 7 to move in the correction welding area 11.

[0069] Specifically, multiple jumpers can be placed along the short side of the battery string. In this embodiment, two jumpers are distributed along the short side of the battery string. To improve the efficiency of jumper preparation and loading, two jumper preparation mechanisms 3 are provided. The two jumper preparation mechanisms 3 are distributed on both sides of the glass plate 7 at the correction welding area 11 along the short side of the glass plate 7. Two jumper loading mechanisms 4 are provided. The two jumper loading mechanisms 4 respectively transport the insulating film and busbar prepared by the two jumper preparation mechanisms 3 to simultaneously complete the preparation and loading of the two jumpers on the battery string. Correspondingly, in this embodiment, two welding heads 613, lifting components 63 and welding head mounting brackets 614 are also provided, divided into two groups to weld the two jumpers respectively. Correspondingly, two sets of adjusting screws 651 are provided to adjust the position of the welding heads 613 in the two sets of welding mounting brackets.

[0070] This invention also discloses a welding method for a jumper wire welding machine, specifically including: The glass plate 7 carrying the battery string is transported to the correction welding area 11 by the feeding mechanism 2. Specifically, multiple transport synchronous belt assemblies 21 transport the glass plate 7 to the correction welding area 11 along the short side of the glass plate 7.

[0071] The jumper wire preparation mechanism 3 prepares insulating film and busbars simultaneously, placing a set of insulating film and a set of busbars side-by-side along the long side of the glass plate 7. Each set of insulating film includes two insulating films, and each set of busbars includes two busbars with one end bent. Specifically, the insulating film preparation line 33 and the busbar preparation line 34 simultaneously obtain insulating film and busbars from the feeding section 31. The insulating film preparation line 33 is coordinated with the insulating film pressing section 332, the insulating film cutting section 333, and the insulating film pulling section 334. Two insulating films are cut and placed on the insulating film placement part 331. The insulating film is fixed by the insulating film fixing part 335. The busbar preparation line 34 cooperates with the busbar pressing part 342, the busbar cutting part 343, and the busbar pulling part 344 to cut two busbars and place them on the busbar placement part 341. The busbars are fixed by the busbar fixing part 346 and the adjacent ends of the two busbars are bent by the busbar bending part 345.

[0072] The correction mechanism 5 corrects the alignment of the glass plate 7 and the battery string through the long side correction part 52 and the short side correction part 51. Specifically, the long side correction component 52221 in the long side correction sub-assembly is raised to the same height as the glass plate 7 by the long side correction height drive component 52222. Then, the long side correction drive component 521 controls the long side correction component 52221 in the long side correction sub-assembly 5222 to approach and abut against the long side of the glass plate 7 through the reciprocating transport component 221. At the same time, the short side correction drive component 511 controls the short side correction component 512 to approach along the long side of the glass plate 7, and the short side drive component 51221 controls the short side correction component 51222 to approach and abut against the short side of the glass plate 7. Through the simultaneous action of the short side correction component 51222 and the long side correction component 52221 on the short and long sides of the glass plate 7, the glass plate 7 moves and is corrected.

[0073] The jumper feeding mechanism 4 simultaneously transports a set of insulating film and a set of busbars side by side. After the glass plate is corrected, the insulating film and busbars are transported to the battery string and stacked on the battery string. Specifically, the first moving part 41 and the second moving part 42 drive the mounting part 43 to move the first adsorption component 44 and the second adsorption component 45 to the insulating film placement part 331 and the busbar placement part 341. The first adsorption component 44 and the second adsorption component 45 simultaneously adsorb the insulating film and the busbar, respectively. The first moving part 41 and the second moving part 42 drive the mounting part 43 to transport the insulating film and the busbars, respectively. 3. The first adsorption component 44 and the second adsorption component 45 are moved to the glass plate 7 above the battery string in the correction welding area 11. The insulating film and busbar are placed in sequence. First, the insulating film is placed along the long side of the glass plate 7. Then, the two busbars are stacked on top of the two insulating films along the long side of the glass plate 7. Then, the first moving part 41 and the second moving part 42 in the jumper feeding mechanism 4 control the heating part 46 to approach the busbar. The heating drive 463 controls the hot air pipe 462 to move downwards towards the busbar and heat the busbar, so that the battery string, the insulating film and the busbar are fixed into a whole.

[0074] The short-side correction drive 511 continues to drive the correction mounting bracket 5121 to approach the glass plate along the long side of the glass plate, causing the two sets of welding parts to move above the two short sides of the battery string. Then, the two sets of welding parts weld the two short sides of the battery string, so that the busbars at the two short sides of the battery string are welded to the busbars in the jumpers at the two short sides respectively. Specifically, the welding drive 611 first cooperates with the lifting assembly 63, so that the lifting drive 631 in the lifting assembly 63 causes the lifting bracket 632 and the adsorption component 633 to adsorb the end of the short side of the battery string, moving it upwards so that the end of the short side of the battery string is aligned with the glass plate. Plate 7 forms an insertion space. Then, the pad drive 621 in the pad assembly 62 causes the pad 622 to be inserted into the insertion space. The lifting drive 631 causes the lifting frame 632 and the adsorption component 633 to descend, placing the end of the short side of the battery string on the pad 622. Then, the welding drive 611 continues to drive the welding head 613 downward to approach the end of the short side of the battery string, welding the busbar at the short side of the battery string to the busbar in the jumper. After welding is completed, the short side correction drive 511 continues to drive the two sets of welding parts away from each other, and the glass plate 7 is transported out by the feeding mechanism 2.

[0075] The above-described welding method of the jumper welding machine ensures the efficiency of jumper loading. After the glass plate is corrected, the jumper loading mechanism 4 loads the jumper. When placing the jumper, the insulating film and busbar inside the jumper are heated and fixed together with the battery string to ensure the accuracy of the jumper's position on the battery string. With the cooperation of the moving welding part, the welding head 613 inside the welding part can move to the overlapping part of the busbar and the busbar inside the jumper at the short side of the battery string, so that the overlapping part is directly facing the welding head 613, further ensuring the accuracy of the jumper welding position and the welding strength.

[0076] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
