Description

Technical Field

[0001] This utility model relates to the technical field of automated wire winding equipment, specifically to an automatic wire winding mechanism with variable winding diameter. Background Technology

[0002] With the rapid development of the photovoltaic industry, photovoltaic cables are increasingly widely used in power transmission and equipment interconnection. During the production and shipping of photovoltaic cables, after connector assembly, the cables typically need to be packaged by winding and securing with cable ties for transportation and subsequent installation. To ensure neat and aesthetically pleasing packaging, and ease of use for customers, the diameter of the wound product needs to meet various specific specifications and can be flexibly adjusted according to the individual needs of different customers.

[0003] However, existing cable reeling mechanisms generally suffer from the following problems: First, most currently use fixed reel diameters or manual adjustment of the winding diameter. When changing the winding diameter, the entire winding module must be replaced or the winding structure dimensions must be frequently adjusted. This relies on worker experience or auxiliary tools, resulting in low efficiency. Furthermore, the varying skill levels of different operators lead to significant fluctuations in the finished product winding dimensions, making it difficult to guarantee product consistency and stability. Second, existing equipment lacks the flexibility to adapt to diverse customer needs and cannot achieve rapid and automatic switching of winding diameters, severely restricting production flexibility and response speed.

[0004] In view of the above problems, there is an urgent need for an automatic winding mechanism with a variable winding diameter. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic cable winding mechanism with a variable winding diameter. This invention enables automatic adjustment of the winding diameter during cable winding, thereby improving production automation, efficiency, and dimensional accuracy.

[0006] This utility model provides an automatic winding mechanism with variable winding diameter, including a turntable assembly, a wire feeding mechanism, and a wire diameter changing assembly. The turntable assembly includes a turntable structure with a wire groove assembly inside, and a connecting fixture for fixing connectors is provided on it. The wire feeding mechanism is arranged on one side of the turntable assembly to carry and guide the wire. The wire diameter changing assembly includes a displacement actuator and a drive mechanism.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present utility model. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present utility model.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0034] like Figure 1 and Figure 9As shown, an automatic winding mechanism with variable winding diameter includes a turntable assembly 1, a wire feeding mechanism, and a winding diameter variable assembly 5. The turntable assembly 1 includes a turntable structure with a winding groove assembly 17 inside, and a connecting fixture 16 for fixing a connector is provided on it. The wire feeding mechanism is arranged on one side of the turntable assembly 1 to carry and guide the wire. The end of the wire is fixed to the connecting fixture 16 through a connector, and thus connected to the winding groove assembly 17 to realize the winding and laying of the wire. The winding diameter variable assembly 5 includes a displacement actuator and a drive mechanism. The drive mechanism is connected to the displacement actuator, and the displacement actuator is connected to the winding groove assembly 17. The displacement actuator can drive the winding groove assembly 17 to reciprocate along the radial direction of the turntable structure. The turntable assembly 1 is installed on a hollow rotating platform 10, and the winding operation is realized by rotation drive.

[0035] The turntable assembly 1 includes a first turntable 12 and a second turntable 6 fixedly disposed above it. The first turntable 12 is mounted on a hollow rotating platform 10. The first turntable 12 and the second turntable 6 are fixedly connected by a support column 7. The displacement actuator is installed between the first turntable 12 and the second turntable 6.

[0036] like Figure 2 , Figure 6 , Figure 7 as well as Figure 8 As shown, the displacement actuator is mounted on the first turntable 12. The displacement actuator includes a movable base 39 and a plurality of sequentially connected transmission components. The movable base 39 is connected to the drive mechanism. A first transmission component 36 is connected to the movable base 39. The first transmission component 36 is connected to a second transmission component 13 and is used to convert the linear movement of the movable base 39 into rotational motion. The second transmission component 13 is connected to a third transmission component 14 and is connected to the coil groove assembly 17. The third transmission component 14 is used to convert the rotational motion into the radial displacement of the coil groove assembly 17, thereby realizing the adjustment of the winding diameter.

[0037] The movable base 39 is connected to the guide component, and linear movement along a preset direction is achieved through the guide component.

[0038] The guide assembly includes a linear bearing 31 and a guide shaft 8. The linear bearing 31 is disposed on the movable base 39, and the guide shaft 8 is disposed on the turntable assembly 12. A sliding connection is formed between the linear bearing 31 and the guide shaft 8.

[0039] A support is provided on the first turntable 12, and a first linear guide rail 15 is provided on the support. A slider is provided at the bottom of the coil groove assembly 17 and is slidably connected to the first linear guide rail 15 through the slider. A third transmission component 14 is installed at the bottom of the coil groove assembly 17. A bearing seat 37 is provided on the support. The second transmission component 13 includes a rotating shaft and gears at both ends of the rotating shaft. The rotating shaft passes through the center of the bearing seat 37, and a gear is arranged on each side of the bearing seat 37. One gear is meshed with the first transmission component 36, and the other gear is meshed with the third transmission component 14.

[0040] The specific working process of the displacement actuator is as follows: When the drive mechanism is started, the moving base 39 moves upward, and the linear bearing 31 also moves upward along the guide shaft 8, thereby causing the first transmission member 36 to move along the guiding direction of the guide shaft 8. The first transmission member 36 drives the rotating shaft to rotate through gear meshing, and the gear at the other end of the rotating shaft rotates accordingly, thereby driving the third transmission member 14 meshing with it to move. Finally, the disc groove assembly 17 above the third transmission member 14 achieves radial displacement.

[0041] In this embodiment, both the first transmission member 36 and the third transmission member 14 are configured as racks. The difference between the two is that the rack of the first transmission member 36 is arranged vertically, while the rack of the third transmission member 14 is arranged horizontally.

[0042] In this embodiment, the coil groove assembly 17, the first transmission component 36, the second transmission component 13, the third transmission component 14, the guide assembly, and the support are all provided in four sets.

[0043] The hollow rotating platform 10 is fixedly connected to the base 11, which is mounted on the large plate of the equipment. The hollow rotating platform 10 is powered by a servo motor and a reducer 9.

[0044] The hollow rotating platform 10 is internally connected to a floating rotating shaft assembly 40. The driving side of the floating rotating shaft assembly 40 is connected to the driving mechanism, and the execution side is connected to the displacement execution mechanism. It is used to transmit the power output by the driving mechanism to the displacement execution mechanism, while isolating the rotational power output by the driving mechanism from other mechanisms, ensuring that other mechanisms operate stably and without interference.

[0045] The drive mechanism consists of a robotic arm mounting plate 32, a first servo motor 34, and a first single-axis robotic arm 33. The robotic arm mounting plate 32 is fixedly mounted on the base 11, and the first single-axis robotic arm 33 is vertically mounted on the robotic arm mounting plate 32. The first single-axis robotic arm 33 is connected to the first servo motor 34, and its sliding block is connected to the drive side of the floating rotary shaft assembly 40 through a floating connecting block 35. The floating rotary shaft assembly 40 has a bearing and a connecting rod at its center. The connecting rod is connected to the bearing and the movable base 39, respectively. This design achieves two key functions: firstly, it ensures that the rotational movement of the hollow rotating platform 10 does not interfere with the normal operation of the drive mechanism; secondly, it effectively transmits the linear driving force output by the first single-axis robotic arm 33 to the movable base 39. Ultimately, this driving force is converted into precise up-and-down linear motion of the movable base 39, completing the expected mechanical action.

[0046] like Figures 3-5 As shown, the wire feeding mechanism includes a wire tensioning assembly 2, a wire lifting assembly 3, and a wire diameter changing assembly 4; the wire is disposed on the wire tensioning arm 20 of the wire tensioning assembly 2, the wire tensioning assembly 2 is connected to the wire lifting assembly 3, and the wire lifting assembly 3 is further connected to the wire diameter changing assembly 4.

[0047] like Figure 4 As shown, the wire lifting assembly 3 includes a second single-axis robotic arm 26 driven by a second servo motor 27. The second single-axis robotic arm 26 is connected to the wire tensioning assembly 2. The second single-axis robotic arm 26 moves in the vertical direction to adjust the height of the wire during the winding process.

[0048] like Figure 5 As shown, the wire take-up diameter changing assembly 4 includes a third single-axis robotic arm 30 driven by a third servo motor 28. A second linear guide rail 29 is provided on the third single-axis robotic arm 30. The wire take-up lifting assembly 3 is mounted on the second linear guide rail 29 via a slider. The third servo motor 28 drives the slider to move laterally along the second linear guide rail 29 so as to realize that the wire feeding angle is synchronously adjusted as the winding diameter changes.
