[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] according to Figures 1 to 3As shown, the utility model is a quick winding and unloading device for photovoltaic busbars, comprising a cabinet 1 and a winding mechanism 2 arranged inside the cabinet 1. A cutting mechanism 3 is provided above the winding mechanism 2 for accurately cutting the busbar to meet the unloading requirements, and a unloading mechanism 4 is also arranged on one side of the winding mechanism 2 so as to carry out orderly unloading processing of the cut busbars. The winding mechanism 2 specifically comprises a support seat 5 and a winding bracket 6 mounted on the support seat 5. The winding bracket 6 is provided with a winding main disk 7 and a clamping mechanism 8, forming a winding station 9 between the two. The winding station 9 clamps an I-shaped disk, and the busbar is wound on the I-shaped disk. A driving motor 10 is installed on the support seat 5. The other end of the winding shaft 11 is fixedly connected to the winding main disk 7, thereby driving the winding main disk 7 to rotate, driving the I-shaped disk to rewind the busbar. In order to ensure that the busbar remains flat during the winding and unloading process, a straightening mechanism 12 is specially set up inside the cabinet 1. The straightening mechanism 12 consists of a supporting main board 13 and a straightening wheel group 14 installed on the supporting main board 13. Before entering the winding station 9, the busbar passes through the straightening wheel group 14 and the cutting mechanism 3 in sequence. The clamping mechanism 8 includes a clamping cylinder 15 installed on the winding bracket 6. The clamping cylinder 15 clamps and fixes the I-shaped disk through the clamping plate 16 connected to it. The clamping plate 16 is also fixed with a winding push rod 17. The winding station 9 is located between the winding main disk 7 and the winding push rod 17. The clamping mechanism 8 cooperates with the winding main disk 7 to ensure that the I-shaped disk remains stable during the winding process.

[0030] A fixed plate 18 is provided in the cabinet body 1, and an adjusting slide rail 19 for adjusting the position of the support seat 5 is provided on the fixed plate 18. An adjusting slider 20 is slidably installed on the adjusting slide rail 19, and the support seat 5 is fixed on the adjusting slider 20. By adjusting the cooperation between the slide rail 19 and the adjusting slider 20, the front and rear position of the support seat 5 can be adjusted, thereby flexibly changing the working position of the winding mechanism 2.

[0031] The straightening wheel assembly 14 includes a first line-entry wheel 21, a first line-pressing wheel 22, a second line-entry wheel 23, and a second line-pressing wheel 24, each forming two independent line-pressing units for precisely straightening the busbar. A first line-pressing space 25 is formed between the first line-entry wheel 21 and the first line-pressing wheel 22, while a second line-pressing space 26 is formed between the second line-entry wheel 23 and the second line-pressing wheel 24. As the busbar passes through these two line-pressing spaces, it is gradually straightened, ensuring flatness and straightness, thereby improving the quality of subsequent winding and unwinding. The support main board 13 is provided with two pressing guide wheels 29 to guide the busbar to the straightening wheel group 14. The support main board 13 is provided with a first fixed shaft 27, and a second fixed shaft 28 is provided below the first fixed shaft 27. A first movable shaft 30 is provided on one side of the first fixed shaft 27. The support main board 13 is provided with a first straightening cylinder 31, which drives the first movable shaft 30 to move toward the first fixed shaft 27; a second movable shaft 32 is provided on one side of the second fixed shaft 28, a second straightening cylinder 33 is provided below the first straightening cylinder 31, and the second straightening cylinder 33 is provided. Drive the second movable shaft 32 to move toward the second fixed shaft 28; the first pressing wheel 22 is rotatably set on the first fixed shaft 27, the first wire-entering wheel is rotatably set on the first movable shaft 30, the second wire-entering wheel 23 is rotatably set on the second fixed shaft 28, and the second pressing wheel 24 is rotatably set on the second movable shaft 32. The first pressing wheel 22 and the second pressing wheel 24 are made of flexible materials, and straighten the two sides of the busbar respectively, so that the busbar can obtain continuous and stable pressing and straightening processing when passing through the straightening wheel group 14, effectively eliminating problems such as wave patterns and bending.

[0032] A speed-changing cylinder 34 is provided below the straightening wheel assembly 14. A gearbox 35 is connected to the speed-changing cylinder 34, which is in turn connected to a speed-changing guide wheel 36. A first limiting wheel 37 and a second limiting wheel 38 are provided below the speed-changing guide wheel 36. The speed-changing cylinder 34 is connected to the gearbox 35, which is used to adjust the speed and transmission ratio of the guide wheels, thereby achieving precise control of the conveying speed of the busbar at different speeds.

[0033] according to Figure 4As shown, the unloading mechanism 4 includes a first unloading rail 39, a unloading slider 40 is slidingly provided on the first unloading rail 39, a connecting plate 41 is provided on the unloading slider 40, a second unloading rail 42 is provided on the connecting plate 41, a chassis support plate 43 is slidingly provided on the second unloading rail 42, and an unloading chassis 44 is provided on the chassis support plate 43. After the busbar is cut off, the I-shaped plate falls on the unloading chassis 44, and the unloading slider 40 drives the connecting plate 41 and the unloading chassis 44 to move along the first unloading rail 39. When it moves to the end, the chassis support plate 43 continues to move along the second unloading rail 42 by inertia, driving the unloading chassis 44 to move to the unloading station and then be manually removed.

[0034] according to Figure 5 As shown, one side of the unloading mechanism 4 is provided with an empty tray replenishment mechanism 45 for automatically replenishing and transferring empty trays. The empty tray replenishment mechanism 45 includes an empty tray storage rack 46, on which is provided an empty tray limiting track 47. The empty tray limiting track 47 includes two limiting shafts. A number of empty trays are placed on the empty tray limiting track 47. The empty tray limiting track 47 is tilted downward toward one end of the winding mechanism 2, allowing the empty trays to slide in a certain order, preventing stacking chaos or jamming, while also ensuring that the empty trays can be smoothly transferred to the replenishment position. The empty tray storage rack 46 is provided with a lifting bracket on the side near the winding mechanism 2. The lifting bracket is equipped with a lifting cylinder 48. The lifting cylinder 48 is connected to a lifting tray 49. The lifting tray 49 is used to receive empty trays that slide off the empty tray storage rack 46 and transfer them to the winding station 9, thereby achieving rapid replacement.

[0035] according to Figure 6 As shown, a gluing mechanism 50 is also provided on one side of the winding station 9. The gluing mechanism 50 includes a gluing base plate 51, on which are provided a tape-releasing roller 52, a tape-guiding roller 53, and a tape-pressing roller 54. A gluing cylinder 55 is also fixed to the gluing base plate 51. The output end of the gluing cylinder 55 is connected to a movable plate 56, which is connected to a buffer plate 57. A buffer spring 58 is provided between the buffer plate 57 and the movable plate 56. The tape-pressing roller 54 is mounted on the buffer plate 57. This can effectively absorb the impact force or pressure fluctuation caused by the thickness or surface unevenness of the busbar during the gluing process, thereby protecting the tape and the busbar surface and ensuring the uniformity and stability of the gluing effect.

[0036] according to Figure 7 As shown, the cutting mechanism 3 includes a shear blade 59 and a cutting motor 60 that drives the shear blade 59 to open and close. A cutting rail 61 is provided at the bottom of the support mainboard 13, and a cutting slider 62 is slidably mounted on the cutting rail 61. The cutting motor 60 is mounted on the cutting slider 62, so that the cutting mechanism 3 can be flexibly adjusted according to actual production needs to accommodate the cutting of busbars of different widths or positions.

[0037] When the utility model is used, after the equipment is started, the bus belt first enters the straightening mechanism 12, and passes through the first pressing space 25 and the second pressing space 26 in sequence, ensuring that the bus belt remains straight when passing through, eliminating waves or bends. At this time, the main reel 7 of the reeling mechanism 2 and the clamping mechanism 8 have already clamped the I-shaped disc. When the bus belt reaches the reeling station 9, the drive motor 10 of the reeling mechanism 2 is started, driving the reeling shaft 11 to rotate, so that the main reel 7 drives the I-shaped disc to start reeling the bus belt. At the same time, the glue cylinder 55 drives the movable plate 56 and the buffer plate 57 to press the glue. The pulley 54 is pressed on the bus belt with appropriate pressure, and the tape is evenly attached to the surface of the bus belt to complete the gluing process. When the winding work is completed, the cutting motor 60 is started, driving the cutting slider 62 and the shearing blade 59 to perform the cutting action, so that the shearing blade 59 accurately cuts the bus belt. Subsequently, the clamping mechanism 8 is reset, and the cut I-shaped disk falls to the unloading chassis 44, and is sent to the unloading area through the unloading mechanism 4. The empty disk replenishing mechanism 45 automatically sends the empty disk to the lifting tray 49, and the lifting cylinder 48 drives the lifting tray 49 to rise, and lifts the empty disk to the winding bracket 6 to continue winding.

[0038] The beneficial effects brought by the utility model are:

[0039] The straightening mechanism of the utility model effectively removes the bends or ripples of the busbar during the input process, ensures the flatness of the busbar during the winding process, and improves the quality of the final product.

[0040] Through the automated unloading and replenishing mechanism, the equipment can operate continuously and stably, reducing manual intervention and downtime, and greatly improving production efficiency.

[0041] The equipment can be adjusted according to different busbar specifications and process requirements and has strong adaptability.

[0042] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
