[0030] The technical solution and effects of this utility model will be further described in detail below with reference to the accompanying drawings.

[0031] In this utility model, Figure 1 This diagram illustrates a battery string assembly 10, comprising 12 battery strings 11, three sets of longitudinal busbars 12, and two sets of transverse busbars 13. The three sets of longitudinal busbars 12 are located at the beginning, middle, and end of the battery string assembly 10, respectively. The three sets of longitudinal busbars 12 are welded to the extended solder strips at the ends of the battery strings 11.

In other common battery string assemblies 10, the number of battery strings 11 may be 10 or other numbers, and the number of longitudinal busbars 12 may be 0 or 1. Each set of longitudinal busbars 12 includes several busbar segments, such as 1, 2, 3, or 4.

[0032] like Figure 2 As shown, this utility model provides a busbar welding machine for manufacturing battery string assemblies, comprising:

[0033] The conveying mechanism 30 is used to convey the component 20 to be welded. The conveying mechanism 30 includes multiple parallel conveyor belts. The component 20 to be welded is conveyed by the conveyor belts. The component to be welded includes a glass plate and multiple battery strings 11 arranged on the glass plate.

[0034] The welding section includes a first welding mechanism 40-1, a second welding mechanism 40-2, and a third welding mechanism 40-3. Along the conveying direction of the conveying mechanism 30, the first welding mechanism 40-1 and the second welding mechanism 40-2 are located on one side of the conveying mechanism 30, and the third welding mechanism 40-3 is located on the other side of the conveying mechanism 30. The second welding mechanism 40-2 is located between the first welding mechanism 40-1 and the third welding mechanism 40-3. Each welding mechanism is used to weld a set of longitudinal confluence belts 12. The first welding mechanism 40-1 and the third welding mechanism 40-3 are used to weld two sets of longitudinal confluence belts 12 located at the beginning and end, respectively, and the second welding mechanism 40-2 is used to weld a set of longitudinal confluence belts 12 located in the middle.

[0035] The tape-making section includes a first tape-making mechanism 50-1 and a second tape-making mechanism 50-2 adjacent to the first welding mechanism 40-1, and a third tape-making mechanism 50-3 adjacent to the third welding mechanism 40-3. The three tape-making mechanisms are used to prepare three sets of longitudinal busbars 12. The first tape-making mechanism 50-1 and the third tape-making mechanism 50-3 are used to prepare two sets of longitudinal busbars 12 at the beginning and end, respectively, and the second tape-making mechanism 50-2 is used to prepare a set of longitudinal busbars 12 located in the middle.

[0036] The conveyor belt is used to transport the bus belts prepared by the first belt making mechanism 50-1, the second belt making mechanism 50-2 and the third belt making mechanism 50-3 to the first welding mechanism 40-1, the second welding mechanism 40-2 and the third welding mechanism 40-3 respectively.

[0037] The battery string lifting section includes a first lifting mechanism 70-1 and a second lifting mechanism 70-2 that are vertically and flexibly disposed above the conveying mechanism 30. The first lifting mechanism 70-1 is used to lift all battery strings 11 on one side of a set of longitudinal busbars 12 located in the middle, and the second lifting mechanism 70-2 is used to lift all battery strings 11 on the other side of a set of longitudinal busbars 12 located in the middle.

[0038] The pressing part includes a first pressing mechanism 80-1, a second pressing mechanism 80-2, and a third pressing mechanism 80-3 that are vertically and flexibly disposed above the conveying mechanism 30. A first lifting mechanism 70-1 is located between the first pressing mechanism 80-1 and the second pressing mechanism 80-2. The second lifting mechanism 70-2 is located between the second pressing mechanism 80-2 and the third pressing mechanism 80-3. The first welding mechanism 40-1, the second welding mechanism 40-2, and the third welding mechanism 40-3 can be moved to directly below the first pressing mechanism 80-1, the second pressing mechanism 80-2, and the third pressing mechanism 80-3, respectively. When the three pressing mechanisms are welding, they press the three sets of longitudinal confluence belts 12 respectively.

[0039] During operation, after the conveying mechanism 30 transports the component 20 to be welded to the welding station, the three belt-making mechanisms prepare three sets of longitudinal busbars 12 respectively. Then, the conveying unit transports the longitudinal busbars prepared by the three belt-making mechanisms to the three welding mechanisms respectively. The string-lifting unit lifts all the battery strings 11 on the glass plate. The three welding mechanisms carrying the longitudinal busbars 12 move to the underside of the three pressing mechanisms. At this time, the battery strings 11 are above the longitudinal busbars 12. The two string-lifting mechanisms and the three pressing mechanisms move down so that the leftover welding strip at the end of the battery strings 11 contacts the longitudinal busbars 12. At the same time, the three pressing mechanisms press the three sets of longitudinal busbars 12 respectively. The three welding mechanisms weld the welding strip and the longitudinal busbars 12 to form the battery string assembly 10. The three welding mechanisms move out of the direct above the conveying mechanism 30. The two string-lifting mechanisms place the battery string assembly 10 on the glass plate. The conveying mechanism transports the glass plate carrying the battery string assembly 10 to the next station.

[0040] In this embodiment, the conveyor belt includes a first conveyor belt mechanism 60-1 adjacent to the first pressing mechanism 80-1. The first conveyor belt mechanism 60-1 is used to transport the busbars prepared by the first belt making mechanism 50-1 and the second belt making mechanism 50-2 to the first welding mechanism 40-1 and the second welding mechanism 40-2 respectively. The bottom of the first conveyor belt mechanism 60-1 is provided with one or two rows of first suction cups. When the bottom of the first conveyor mechanism 60-1 is provided with a row of first suction cups, the first conveyor mechanism 60-1 can first adsorb and transport the longitudinal busbar 12 prepared by the first belt making mechanism 50-1 to the first welding mechanism 40-1, and then adsorb and transport the longitudinal busbar 12 prepared by the second belt making mechanism 50-2 to the second welding mechanism 40-2; when the bottom of the first conveyor mechanism 60-1 is provided with two rows of first suction cups, the first conveyor mechanism 60-1 can adsorb the two sets of longitudinal busbars 12 prepared by the first belt making mechanism 50-1 and the second belt making mechanism 50-2 in sequence or simultaneously, and then place them on the first welding mechanism 40-1 and the second welding mechanism 40-2 at the same time. The distance between the first welding mechanism 40-1 and the second welding mechanism 40-2 is adapted to the distance between the two rows of first suction cups.

[0041] like Figure 3 As shown, in another embodiment of this utility model, the conveyor belt includes a first conveyor belt mechanism 60-1 and a second conveyor belt mechanism 60-2 adjacent to the first pressing mechanism 80-1, and a third conveyor belt mechanism 60-3 adjacent to the third pressing mechanism 80-3.

The second conveyor belt mechanism 60-2 is used to transport the busbar prepared by the second belt making mechanism 50-2 to the second welding mechanism 40-2. The third conveyor belt mechanism 60-3 is used to transport the busbar prepared by the third belt making mechanism 50-3 to the third welding mechanism 40-3. Each moving mechanism has a row of first suction cups at its bottom.

[0042] like Figure 5 As shown, in this utility model, the first pressing mechanism 80-1, the second pressing mechanism 80-2, and the third pressing mechanism 80-3 all include a lifting plate 81 and a row of pressing members 82 elastically mounted on the bottom of the lifting plate 81, and the pressing members 83 are connected to the welding strip. Optionally, the conveying part also includes a row of second suction cups disposed on the lifting plate 81 of the third pressing mechanism 80-3. The second suction cups are located on the side of the pressing members 82 that is relatively far away from the lifting part. The lifting plate 81 can also move horizontally to integrate the second suction cups onto the lifting plate 81. The pressing members 82 on the third suction cups share a common lifting drive, which can save costs. The second suction cups are used to transport the busbar prepared by the third belt making mechanism 50-3 to the third welding mechanism 40-3.

[0043] In this utility model, the first belt-making mechanism 50-1 and the third belt-making mechanism 50-3 are mirror images of each other, as shown below. Figure 4 As shown, the first belt-controlling mechanism 50-1 includes a first longitudinal beam 511, a first belt puller 512, a first cutter 513, and a first carrier plate 514. The first belt puller 512 and the first cutter 513 are mounted on the first longitudinal beam 511, and the belt puller is slidably connected to the first longitudinal beam 511. The first carrier plate 514 is located below the moving path of the first belt puller 512. The second belt-controlling mechanism 50-2 includes a second longitudinal beam 521, a second belt puller 522, a second cutter 523, and a second carrier plate 524. The second belt puller 522 and the second cutter 523 are mounted on the second longitudinal beam 521, and the second belt puller 522 is slidably connected to the second longitudinal beam 521. The second carrier plate 524 is located below the moving path of the second belt puller 522. The second carrier plate 524 has several notches, and lifting members 525 are provided in the notches. Rotating pressure plates 526 are provided on both sides of the notches.

[0044] like Figure 7As shown, in this utility model, the first welding mechanism 40-1, the second welding mechanism 40-2, and the third welding mechanism 40-3 all include a movable beam 41 and an electromagnetic heating element 42 disposed on the movable beam 41. The movable beam 41 can move horizontally above the conveying mechanism 30.

[0045] like Figure 5 As shown, the belt-making section also includes a fourth belt-making mechanism 50-4. The fourth belt-making mechanism 50-4 is located above the output or input end of the conveying mechanism 30. The fourth belt-making mechanism 50-4 includes a fourth crossbeam 541, a fourth belt puller 542, a fourth cutter 543, and a fourth carrier plate 544. The fourth belt puller 542 and the fourth cutter 543 are mounted on the fourth crossbeam 541. The fourth belt puller 542 is slidably connected to the fourth crossbeam 541. The fourth carrier plate 544 is located below the moving path of the fourth belt puller 542 and can reciprocate above the conveying mechanism 30 along the conveying direction of the conveying mechanism 30. Figure 8 As shown, both the first string lifting mechanism 70-1 and the second string lifting mechanism 70-2 include a lifting frame 71, and multiple first adsorption elements 72 and several second adsorption elements 73 installed parallel to the bottom of the lifting frame 71. The second adsorption elements 73 are located between the first adsorption elements 72. The lifting frame 71 can drive the first adsorption elements 72 and the second adsorption elements 73 to move up and down. The bottom of the first adsorption elements 72 and the second adsorption elements 73 are provided with suction cups, which are used to adsorb the battery string and the transverse busbar 13, respectively. The first adsorption elements 72 and the second adsorption elements 73 are set as needed according to the number of battery strings 11 and transverse busbar 13. The fourth belt making mechanism 50-4 is used to prepare the transverse busbar 13. After the fourth carrier plate 544 transports the transverse busbar 13 to the bottom of the string lifting part, the first string lifting mechanism 70-1 and the second string lifting mechanism 70-2 move down to adsorb the transverse busbar 13. After the first string lifting mechanism 70-1 and the second string lifting mechanism 70-2 simultaneously adsorb and lift the battery string 11 and the transverse busbar 13, the three welding mechanisms carry the corresponding longitudinal busbar 12 and move to below the string lifting part. The first string lifting mechanism 70-1 and the second string lifting mechanism 70-2 move down so that the welding strip overlaps with the longitudinal busbar 12 and the transverse busbar 13 overlaps with the transverse busbar 13 located at the first and last ends. After the pressing part presses down, the welding mechanism performs welding.

[0046] It should be noted that in this utility model, the pull handles of each band-making mechanism are used to pull out the busbar. After the cutter cuts the busbar, the pull handles place the busbar on the carrier plate. Generally, the longitudinal busbar 12 located in the middle needs to be welded to the junction box, usually including 2-4 busbar segments, with the ends of two adjacent busbar segments folded upwards. After the second band-making mechanism 50-2 prepares the longitudinal busbar 12 and places it on the second carrier plate 524, the adjacent ends of two busbar segments are located above the lifting member 525 in the notch. After the rotating pressure plate 526 rotates and presses down on the busbar segments, the lifting member 525 moves upwards, which can fold the adjacent ends of two busbar segments upwards. One to three lifting members 525 can be provided as needed.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the present utility model.
