[0058] In a specific embodiment, Figure 1 As shown, the insulating tape laying device includes an insulating tape roll 2 and an insulating tape pulling device 4. The insulating tape roll 2 is located at the first end of the carrying device 1. The insulating tape pulling device 4 pulls the insulating tape from the insulating tape roll 2 and moves toward the second end of the carrying device 1. After the insulating tape is cut, the insulating tape is laid on the carrying device 1. Figure 1 The insulating tape pulling device 4 shown in FIG. 1 has moved to the second end (ie, the left end in the figure) of the carrying device 1 .

[0059] The main bus bar laying device includes a main bus bar roll 3 and a main bus bar pulling device 5. The main bus bar roll 3 is located at the second end of the carrier device 1. The main bus bar pulling device 5 pulls the bus bar from the main bus bar roll 3 and moves toward the first end of the carrier device 1. After the bus bar is cut, the cut main bus bar is laid on the insulating tape of the carrier device 1.

[0060] The insulating tape laying device further includes an insulating tape pressing device and an insulating tape cutting device provided at the first end of the carrying device 1. After the insulating tape pulling device 4 pulls the insulating tape to a first predetermined length, the insulating tape pressing device presses the insulating tape, and the insulating tape cutting device cuts the pressed insulating tape.

[0061] The main busbar placement device further includes a main busbar pressing device 6 and a main busbar cutting device 7 disposed at the second end of the carrier device 1. After the main busbar pulling device 5 pulls the busbar to a second predetermined length, the main busbar pressing device 6 presses the busbar, and the main busbar cutting device cuts the pressed busbar. The first predetermined length and the second predetermined length may be equal or different.

[0062] The insulating tape laying device is configured to lay one or at least two parallel insulating tapes on the carrying device 1 , and the main bus bar laying device is configured to lay one main bus bar on each insulating tape.

[0063] When laying at least two parallel insulating tapes, at least two parallel insulating tape pulling devices 4 can simultaneously pull at least two parallel insulating tapes, and after cutting, at least two parallel insulating tapes are laid on the carrier device 1. Similarly, at least two parallel main bus bar pulling devices 5 can simultaneously pull at least two parallel bus bars, and after cutting, at least two parallel main bus bars are obtained, which are respectively stacked on the insulating tapes. Figure 3 Two side-by-side insulating tape pulling devices 4 and two side-by-side main busbar pulling devices 5 are shown.

[0064] Preferably, one of the insulating tape segments includes at least two segments arranged in a straight line and spaced apart along its length. This allows the main busbar between the two segments to be conductive, facilitating electrical connection to other busbars. In one embodiment, the specific process for laying the insulating tape segments on the carrier device 1 is as follows: at least two insulating tape pulling devices 4 each pull a segment of insulating tape. One of the insulating tape pulling devices 4 pulls the insulating tape to a first preset position, cuts the pulled insulating tape, and lays the cut first segment of insulating tape on the carrier device 1. The insulating tape pulling device 4 then pulls the insulating tape from the insulating tape roll 2 again, moves toward the second end of the carrier device 1 to a second preset position, and cuts the insulating tape to obtain a second segment of insulating tape.

The first and second segments of insulating tape are arranged in a straight line and spaced apart along their length on the carrier device 1. Another insulating tape pulling device 4 pulls an insulating tape parallel to the first and second segments of insulating tape to a preset position and cuts it.

[0065] In this embodiment, the busbar assembly production equipment also includes a sub-busbar providing device and a sub-busbar welding device. The sub-busbar providing device is configured to provide a sub-busbar and place the sub-busbar on the main busbar, and the sub-busbar welding device welds the sub-busbar to the main busbar.

[0066] Preferably, if Figure 2 and Figure 4 As shown, the sub-busbar providing device includes a carrying platform 12, a bending mechanism 13 and a sub-busbar conveying device 14;

[0067] The supporting platform 12 is used to support the busbar to be bent. When the busbar is located on the supporting platform 12 and one end extends out of the supporting platform 12, the sub-busbar conveying device 14 presses the busbar onto the supporting platform 12, and the bending mechanism 13 bends the part of the busbar extending from the supporting platform 12 to form the sub-busbar. The sub-busbar conveying device 14 absorbs the sub-busbar and conveys the sub-busbar to a predetermined position of the main busbar on the supporting device 1, and the sub-busbar welding device 15 welds the sub-busbar to the main busbar.

[0068] The bending mechanism 13 includes a lifting component that can be raised and lowered. When the lifting component rises, it pushes the busbar extending from the supporting platform 12 to bend the busbar into an L-shaped sub-busbar.

[0069] The specific structure of the sub-busbar transport device 14 can be as follows: Figure 5As shown, it includes a frame 141, a mounting block 144 that can be raised and lowered and moved laterally relative to the frame 141, and a guide post 145 mounted on the mounting block 144. The guide post 145 can move up and down relative to the mounting block 144, and a spring 146 is provided between the guide post 145 and the mounting block 144. Specifically, a limit block 148 is fixed to the guide post 145, and the spring 146 is installed between the mounting block 146 and the limit block 148. The spring 146 applies a downward elastic force to the lower limit block 148, thereby applying a downward elastic force to the guide post 145. The lower end of the guide post 145 is provided with an adsorption component 147, which can specifically be a suction cup. When the guide post 145 descends so that the adsorption component 147 presses on the component to be adsorbed (the busbar to be adsorbed), the spring 146 applies a downward elastic force to the guide post 145, so that the adsorption component on the guide post 145 can elastically contact the busbar to be adsorbed.

[0070] Furthermore, the sub-busbar handling device 14 also includes a lifting frame 142, a lifting mechanism for driving the lifting frame 142 to move upward and downward, and a transverse cylinder 143 mounted on the lifting frame 142. The transverse cylinder 143 can drive the mounting block 144 to move horizontally, and the lifting mechanism can adjust the height of the mounting block 144 when driving the lifting frame 142 to move upward and downward.

[0071] The sub-busbar providing device further includes a sub-busbar pulling device 9, a sub-busbar pressing device 10 and a sub-busbar cutting device 11;

[0072] When the sub-busbar pulling device 9 pulls the busbar until the front end of the busbar extends out of the carrying platform 12, the sub-busbar pressing device 10 presses the busbar pulled by the sub-busbar pulling device, and the sub-busbar cutting device 11 cuts the busbar, and the cut busbar is placed on the carrying platform 12. Then, the sub-busbar conveying device 14 presses the busbar on the carrying platform 12, and the bending mechanism 13 bends the portion of the busbar that extends out of the carrying platform 12.

[0073] In this embodiment, if Figure 3 As shown, the sub-busbar welding device 15 is arranged at the end position of the second end of the carrying device 1;

[0074] The sub-busbar welding device 15 includes a welding head that can be raised and lowered. After the main busbar pulling device 5 pulls the busbar from the main busbar roll 3 to a predetermined position, the welding head rises, and the sub-busbar conveying device 14 places the adsorbed sub-busbar at the position of the main busbar corresponding to the welding head (at this time, the main busbar is the uncut busbar pulled by the main busbar pulling device 35), and presses the sub-busbar. The welding head welds the sub-busbar to the main busbar, and then the main busbar pulling device 5 continues to pull the busbar for a certain distance, and then cuts it to form the main busbar laid on the carrying device 1.

[0075] In this embodiment, since at least two parallel insulating tapes and main bus bars corresponding to the insulating tapes are laid on the carrier device 1, in order to improve welding efficiency, preferably, the hot pressing device 8 is configured to simultaneously weld at least two parallel insulating tapes and the main bus bars on the carrier device 1.

[0076] Specific as Figure 6 As shown, the hot pressing device 8 includes a strip-shaped mounting beam 81 , and at least two rows of hot pressing parts 821 are provided on the mounting beam 81 . The hot pressing parts 821 in each row are arranged at intervals along the length direction of the mounting beam 81 .

[0077] More specifically, at least two hot pressing blocks 82 are arranged at intervals along the length direction on the mounting beam 81, and at least two hot pressing parts 821 are arranged at intervals along the width direction of the mounting beam 81 on each hot pressing block (the figure shows that two hot pressing parts 821 are arranged on each hot pressing block 82), thereby forming at least two rows of hot pressing parts 821 along the length direction on the mounting beam 81, so that two parallel main bus bars can be welded at the same time.

[0078] In which, the hot pressing device 8 also includes a driving mechanism for driving the mounting beam 8 to move from one side of the supporting device 1 toward the top of the supporting device 1 and descend. When welding is required, the driving mechanism drives the mounting beam 8 to move to the top of the supporting device 1 and then descend, so that each row of hot pressing parts 821 corresponds to a main bus bar.

[0079] The busbar assembly production equipment provided by the present invention can efficiently produce busbar assemblies, which can be used as bypass busbars in battery strings. Moreover, when the busbar assembly is used as a bypass busbar in a battery string, short circuits with adjacent battery strings can be avoided.

[0080] The following describes a specific process of producing a busbar using the busbar assembly production equipment provided by the present invention according to a specific embodiment.

[0081] First, the two insulating tape pulling devices 4 are controlled to pull the insulating tapes in parallel from the insulating tape roll 2 and toward the second end ( Figure 1 The insulating tape traction device 4 moves to the left end of the carrier device 1 in the middle, and one of the insulating tape traction devices 4 tractions the insulating tape to a first preset position, cuts the traction tape, and lays the cut first section of the insulating tape on the carrier device 1. The insulating tape traction device 4 then tractions the insulating tape from the insulating tape roll 2 toward the second end of the carrier device 1 to a second preset position, and cuts the insulating tape to obtain a second section of the insulating tape. The insulating tape traction device 4 tractions the cut second section of the insulating tape to a third preset position, and the insulating tape is laid on the carrier device 1; wherein the first section of the insulating tape and the second section of the insulating tape are arranged in a straight line with a gap along the length direction on the carrier device 1. Another insulating tape traction device 4 tractions the insulating tape to a fourth preset position, and cuts the insulating tape to obtain an insulating tape laid on the carrier device 1 and parallel to the first and second sections of the insulating tape.

[0082] Control the two main busbar pulling devices 5 to pull parallel busbars from the main busbar roll 3 and move them toward the first end ( Figure 1 Move to the right end of the

[0083] During the process of laying the insulating tape and the main bus bar, or before laying the insulating tape and the main bus bar, the sub-bus bar pulling device 9 is controlled to pull the bus bar until the front end of the bus bar extends out of the supporting platform 12, the sub-bus bar pressing device 10 presses the bus bar pulled by the sub-bus bar pulling device 9, and the sub-bus bar cutting device 11 cuts the bus bar, and the cut bus bar is located on the supporting platform 12.

[0084] The adsorption component 147 of the sub-busbar transport device 14 is controlled to translate and descend to press on the busbar on the carrier 12, and the bending mechanism 13 rises to bend the portion of the busbar extending out of the carrier 12 to form an L-shaped sub-busbar.

[0085] When the main busbar pulling device 5 pulls the busbar to a predetermined position, the welding head of the sub-busbar welding device 15 moves from bottom to top (the welding head is located at the second end of the carrying device 1), and the sub-busbar carrying device 14 places the adsorbed sub-busbar at the position of the main busbar corresponding to the welding head and presses the sub-busbar, and the welding head welds the sub-busbar to the main busbar.

[0086] Then, the main busbar pulling device 5 pulls the busbar to continue moving. After pulling a certain length, the main busbar pressing device 6 presses the busbar, and the main busbar cutting device 7 cuts the pressed busbar. The two parallel main busbars obtained by cutting are laid on the first and second sections of the insulating tape, and the other is laid on another insulating tape parallel to the first and second sections of the insulating tape. Then, the insulating tape hot pressing device 8 is controlled to hot press the insulating tape and the main busbar on the supporting device 1, so that the insulating tape and the main busbar are fixed together. Of course, it is understandable that the insulating tape and the main busbar can also be fixed together before the sub-busbar is welded to the main busbar.
