Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically a braided, omnidirectional structure. Background Technology

[0002] In the fields of electronic manufacturing and wire harness processing, cable end treatment is one of the key process steps. For cables with braided shielding layers, the braided layer usually needs to be separated from the internal core wires before subsequent welding or terminal crimping, a process known as "unwinding." Traditional unwinding devices mostly adopt a horizontal eccentric rotation structure. The basic principle is that a drive mechanism drives a round tube to be inserted between the braided layer and the core wires, causing the round tube to generate eccentric reciprocating motion, which, combined with the rotational motion, unfolds the braided layer. However, this type of structure has obvious defects in practical applications: because the round tube generates a forced spatial motion trajectory during eccentric rotation, it is easy for the cable body to twist or bend, which not only affects the appearance quality of the wire harness but may also damage the internal conductor insulation layer or cause core wire breakage, thus affecting the stability of subsequent automated processing and the yield of finished products. In addition, the rotating support components in existing structures mostly use fixed bearings or sliding guides, which lack sufficient angle self-adaptation capability and are difficult to guarantee the stability and centering of the round tube in multi-degree-of-freedom motion. Especially in high-speed or high-precision operation scenarios, problems such as vibration, jamming, or positioning deviation are prone to occur. Therefore, how to achieve effective swaying and unwinding while avoiding deformation of the wire body and maintaining its spatial stability has become a pressing technical challenge in this field. Although existing technologies have attempted to alleviate the above problems by improving the transmission mechanism or adding guiding devices, they have not fundamentally overcome the structural limitations caused by motion interference. Therefore, this utility model proposes a braided swaying and unwinding universal structure. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a braided and unwinding universal structure to avoid twisting and damage to the wire body during braiding, while ensuring that the wire itself does not shift position, reducing the difficulty of subsequent processing and improving the stability of the equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A woven, omnidirectional structure includes a frame, a drive motor fixedly mounted on one side of the frame, and a rotating wheel connected to the output of the drive motor via a transmission wheel and belt. A rotating shaft is fixedly connected inside the rotating wheel, and a slide is fixedly connected to one end of the rotating shaft. A movable eccentric slider is mounted on one side of the slide, and a spherical bearing is installed inside the eccentric slider. A circular tube is installed inside the spherical bearing. A fixed bracket is also fixedly mounted on the frame, and a cam follower is fixedly mounted on one side of the fixed bracket. The combination of the spherical bearing and the cam follower effectively avoids the drawbacks of horizontal eccentric rotational motion. The characteristics of the spherical bearing allow for arbitrary angle changes in the circular tube, and the cam follower provides sufficient support for the circular tube during the circumferential motion of the rotating shaft, making the mechanism more flexible and stable.

[0005] Preferably, a spring is provided between the carriage and the eccentric slider.

[0006] Preferably, the device frame includes a fixed frame and a movable plate. The drive motor and the fixed bracket are both fixedly mounted on the movable plate, and the fixed frame is fixed with a sliding groove. The bottom of the movable plate is fixed with a slider. The movable plate can move and translate on the fixed frame, and a cylinder for driving the movable plate is also fixedly connected to the fixed frame.

[0007] Preferably, a fixed plate is fixedly installed on the device frame, and a sliding plate is slidably connected to one side of the fixed plate via a rail. A pneumatic finger is fixedly installed on the sliding plate, and a clamp is connected to the output end of the pneumatic finger.

[0008] Preferably, a second fixing plate is also fixedly installed on the device frame, a second sliding plate is connected to the second fixing plate via a second track, a second pneumatic finger is installed on the second sliding plate, and a secondary positioning gripper is connected to the output end of the second pneumatic finger.

[0009] Preferably, a drive cylinder for driving the sliding plate is fixedly installed on the fixed plate.

[0010] Preferably, a drive cylinder for driving the sliding plate is fixedly installed on the fixed plate.

[0011] Preferably, it also includes a gripper mechanism for securing the wire and a placement groove.

[0012] Beneficial effects: This invention effectively avoids the drawbacks of horizontal eccentric rotational motion by using the combination of spherical bearings and cam follower. The characteristics of spherical bearings allow for arbitrary angle changes of the circular tube, and the cam follower provides sufficient support for the circular tube during the circumferential motion of the rotating shaft, making the mechanism more flexible and stable.
