[0027] The photovoltaic busbar is constructed by mounting a lower and upper roller pressing die on a support frame, with the upper and lower roller pressing dies arranged symmetrically opposite each other. A lifting and adjusting structure is provided between the upper roller pressing die and the support frame. This structure allows the upper roller pressing die to slide vertically along the support frame, either lowering it closer to the lower roller pressing die or raising it away from the lower roller pressing die. This allows for adjustment of the distance between the upper and lower roller pressing dies, thereby adjusting the roller pressing thickness of the photovoltaic busbar. Furthermore, the upper roller pressing die and... The lower roller pressing module is driven by a drive structure to rotate the active roller. The friction between the outer walls of the active roller and the driven roller drives the driven roller to rotate, causing the driven rollers of the upper and lower roller pressing modules to rotate in opposite directions. This achieves the purpose of processing photovoltaic busbars and transporting them simultaneously. In addition, unlike the existing technology that relies on gears to transmit power between the active and driven rollers, the upper and lower roller pressing modules of this invention transmit power through static friction between their outer walls. This results in smoother power transmission and prevents jamming between the active and driven rollers. It also allows for active adjustment of the roller pressing distance between the upper and lower roller pressing modules as needed, improving the transmission smoothness between the active and driven rollers.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] A rolling device for a photovoltaic busbar, such as Figures 1-4As shown, the system includes a support frame 1, on which a lower roller pressing die 3 and an upper roller pressing die 2 are mounted. The upper roller pressing die 2 and the lower roller pressing die 3 are symmetrically arranged on the support frame 1. The upper roller pressing die 2 is vertically mounted on the support frame 1. A lifting adjustment structure 4 is provided between the upper roller pressing die 2 and the support frame 1. The lifting adjustment structure 4 is used to drive the upper roller pressing die 2 to move closer to or further away from the lower roller pressing die 3. Both the upper roller pressing die 2 and the lower roller pressing die 3 include a drive structure 21, a driving roller 22, and a driven roller 23. The driving roller 22 and the driven roller 23 are in contact with each other. The drive structure 21 drives the driving roller 22 to rotate the corresponding driven roller 23. In this embodiment, the drive structure 21... The system includes a drive motor 211 and a reduction module 212. The drive motor 211 drives the active roller 22 to rotate through the reduction module 212. The lifting and adjusting structure 4 includes a motor drive assembly 41, a transmission assembly 42, and a lead screw pair structure 43. The output end of the lead screw pair structure 43 is connected to the upper roller pressing module 2. The motor drive assembly 41 drives the upper roller pressing module 2 to slide up and down on the support frame 1 through the transmission assembly 42 and the lead screw pair structure 43. The motor drive assembly 41 drives the lead screw pair structure 43 to run through the transmission assembly 42, so that the lead screw of the lead screw pair structure 43 drives the upper roller pressing module 2 to slide up and down on the support frame 1. The motor drive assembly 41 is used to provide a strong and stable driving force. The lead screw pair structure 43... 3. This can improve the accuracy of the lifting and sliding of the upper roller pressing module 2. In this embodiment, the motor drive assembly 41 includes a servo motor 411 and a synchronous belt 412. The transmission assembly 42 is set as a worm gear 421 and a turbine. The servo motor 411 drives the worm gear 421 to rotate through the synchronous belt 412. The worm wheel 422 is coaxially fixed on the lead screw of the lead screw pair. Therefore, the rotation of the worm gear 421 drives the turbine to rotate, and the rotation of the worm wheel 422 drives the synchronous belt 412 to run the lead screw pair structure 43. It also includes a control platform 7. The support frame 1 is slidably set on the control platform 7. The control platform 7 is provided with a busbar conveyor roller group 71 corresponding to the support frame 1. A linear adjustment module 72 is provided between the support frame 1 and the control platform 7. The linear adjustment module 72 is used for the linear adjustment. The linear adjustment module 72 is used to adjust the relative position of the busbar conveying roller assembly 71 and the support frame 1. By using the linear adjustment module 72 to drive the support frame 1 to translate on the control platform 7, the alignment between the return strip conveying roller and the upper roller pressing module 2 and the lower roller pressing module 3 on the support frame 1 can be adjusted, which is beneficial to improving the roller pressing and conveying effect of the photovoltaic busbar. In this embodiment, the linear adjustment module 72 includes a handwheel 721, a lead screw assembly 722 and a sliding seat 723. By turning the handwheel 721, the lead screw assembly 722 drives the sliding seat 723 to slide on the control platform 7. The support frame 1 is fixed on the sliding seat 723, so the translation of the sliding seat 723 will drive the support frame 1 to move synchronously.

[0035] like Figure 1As shown, the upper roller pressing die 2 also includes a lifting seat assembly 24 that is lifted and lowered on the support frame 1, and mounting seats 25 connected to both sides of the lifting seat assembly 24. The power output end of the lifting adjustment structure 4 is connected to the lifting seat assembly 24. The two ends of the active roller 22 of the upper roller pressing die 2 are rotatably connected to the lifting seat assembly 24, and the two ends of the driven roller 23 of the upper roller pressing die 2 are rotatably connected between the two mounting seats 25, so that the lifting adjustment structure 4 can drive the lifting seat assembly 24 to drive the mounting seats 25 to lift and lower synchronously, thereby realizing the overall lifting and sliding of the upper roller pressing die 2 relative to the support frame 1. A tension adjustment structure is provided between the lifting seat assembly 24 and the mounting seats 25. The tension adjustment structure is used to adjust the tightness of the fit between the driven roller 23 and the active roller 22. The tightness adjustment structure can be used to adjust the tightness of the fit between the outer walls of the active roller 22 and the driven roller 23, thereby adjusting the power transmission between them. The structure includes an adjusting plate 241, a bolt 242, and a waist-shaped hole 243. The waist-shaped hole 243 is vertically opened on the adjusting plate 241. The adjusting plate 241 is fixedly connected to the mounting base 25. The bolt 242 passes through the waist-shaped hole 243 to fix the adjusting plate 241 to the lifting seat assembly 24. The positional relationship between the mounting base 25 and the lifting seat assembly 24 can be adjusted by adjusting the vertical position of the adjusting plate 241 relative to the lifting seat assembly 24, thereby adjusting the contact and clamping force between the active roller 22 and the driven roller 23. The adjusting plates 241 on both sides of the upper roller pressing module 2 are respectively located on the outer side of the support frame 1. When the lifting and adjusting structure 4 drives the upper roller pressing module 2 to slide up and down on the support frame 1, the two sides of the upper roller pressing module 2 are guided and slid with the side wall of the support frame 1 through the corresponding adjusting plates 241. The adjustment plates 241 on both sides can improve the consistency of the lifting direction of the upper roller pressing assembly on the support frame 1.

[0036] like Figures 3-4As shown, the two ends of the active roller 22 are connected to the lifting seat assembly 24, and the two ends of the driven roller 23 are connected to the corresponding mounting seats 25 via bearings 26. The bearings 26 are added to improve the smoothness of rotation between the active roller 22 and the lifting seat assembly 24, and between the driven roller 23 and the mounting seat 25, while reducing the noise generated when the active roller 22 and the driven roller 23 rotate. A first elastic element 5 is provided between the mounting seat 25 and the corresponding lifting seat assembly 24. One end of the first elastic element 5 abuts against the lifting seat assembly 24, and the other end of the first elastic element 5 abuts against the mounting seat 25. The elastic clamping force of the first elastic element 5 reduces the vibration of the photovoltaic busbar during the rolling process of the upper and lower roller pressing assemblies. The vibration of the upper and lower roller pressing assemblies during operation is reduced, and the stability of their operation is improved. Second elastic elements 6 are provided on the mounting seats 25 on both sides corresponding to the lower roller pressing die 3. When the upper roller pressing die 2 is relatively close to the lower roller pressing die 3, the mounting seats 25 corresponding to the upper and lower roller pressing assemblies 2 and 3 are elastically supported by the second elastic elements 6. When the upper roller pressing die 2 is close to the lower roller pressing die 3, the second elastic elements 6 are compressed and accumulate elastic potential energy. This elastic potential energy can be used to elastically press the upper roller pressing die 2 and the lower roller pressing die 3 together, buffering the vibration generated during their operation, reducing operating noise, and extending the service life of the equipment.

[0037] The basic working principle of this utility model is as follows: A lower roller pressing module 3 and an upper roller pressing module 2 are set on a support frame 1, and the upper roller pressing module 2 and the lower roller pressing module 3 are arranged symmetrically opposite each other on the support frame 1. A lifting adjustment structure 4 is provided between the upper roller pressing module 2 and the support frame 1. The lifting adjustment structure 4 can drive the upper roller pressing module 2 to slide vertically on the support frame 1, thereby causing the upper roller pressing module 2 to descend and move closer to the lower roller pressing module 3, or to rise and move away from the lower roller pressing module 3. Thus, the distance between the upper roller pressing module 2 and the lower roller pressing module 3 can be adjusted as needed, thereby adjusting the roller pressing thickness of the photovoltaic busbar. In addition, both the upper roller pressing module 2 and the lower roller pressing module 3 are driven by a drive structure 21 to drive the active roller 22 to rotate. By utilizing the friction between the outer wall of the active roller 22 and the outer wall of the driven roller 23, the driven roller 23 is driven to rotate, causing the driven rollers 23 of the upper roller pressing die group 2 and the lower roller pressing die group 3 to rotate in opposite directions. This achieves the purpose of transporting photovoltaic busbars while processing them. In addition, unlike the existing technology where the active roller 22 and the driven roller 23 are driven by gears, the active roller 22 and the driven roller 23 of this invention are driven by the static friction between their outer walls. This results in a smoother power delivery and prevents jamming between the active roller 22 and the driven roller 23. It also allows for active adjustment of the roller pressing distance between the upper roller pressing die group and the lower roller pressing die group as needed, improving the smoothness of the transmission between the active roller and the driven roller.

[0038] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
