Description

Technical Field

[0001] The utility model belongs to the field of winding and packaging equipment, in particular to an auxiliary winding and packaging device for packaging passenger car wiring harnesses. Background Art

[0002] Bus wiring harnesses come in a wide variety of types, including control and signal cables, as well as the protective conduits they contain. Some harnesses incorporate plugs and terminals that match bus connectors, allowing for straightforward plugging and connection, eliminating the need for rewiring, welding, or extensive cutting. However, since bundles vary in diameter, length, and end structure, fully automated packaging is not feasible, and therefore bundling is typically accomplished manually with the aid of packaging equipment.

[0003] Currently, the packaging equipment used for integrated wiring harnesses for buses primarily consists of a chassis, drive motor, turntable, and positioning rollers. For example, CN210364502U discloses a wiring harness packaging machine, which includes a frame, electrical box, counterweight plate, operating platform, motion mechanism, protective cover, right roller assembly, table rollers, tray mechanism, and human-machine interface. The motion mechanism includes a cylinder, guide post, guide sleeve, cylinder adapter plate, sliding support plate, bracket, spool assembly, servo motor, and reducer. The spool assembly includes a spool, rotating shaft, spool bearing seat, and bearings. The use of a servo motor and reducer reduces labor intensity and improves production efficiency. However, such equipment still has some problems in actual application. For example, workers walking around the equipment or workers operating the equipment are prone to collision with the sharp edges and corners of the frame. In addition, since the equipment is not open enough and the bus integrated wiring harness is relatively loose before packaging, it is easy to hook on the protective cover, affecting the packaging efficiency and even damaging the terminals and plugs at the end of the wiring harness. In addition, the workers' operating angle is also reduced, making it inconvenient to take and put the wiring harness back and forth, and its practicality is not very strong. Utility Model Content

DETAILED DESCRIPTION

[0018] To more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein may be combined with each other unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appearing below merely indicate the same directions as in the drawings themselves and do not limit the structure.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figure 1 、 Figure 2 and Figure 3 As shown, the auxiliary winding and packaging device for bus wiring harness packaging provided by the utility model includes a frame 1, which includes multiple square tubes. A table 2 is provided on the top of the frame 1, and a drive mechanism is provided below the table 2. The drive mechanism is preferably a reduction motor. The control end of the drive mechanism is provided with a pedal switch 3 electrically connected thereto. A rotating support assembly 4 is provided above the table 2 and is transmission-connected to the drive mechanism. Among them, a worker steps on the pedal switch 3 to control the start and stop of the drive mechanism. The drive mechanism is used to provide power to the rotating support assembly 4, and the rotating support assembly 4 provides a winding node for the integrated wiring harness for buses.

[0021] On this basis, the rotary support assembly 4 provided by the present invention includes a central axis 41, a turntable 42 is provided on the top of the central axis 41, a cross support frame 43 is provided on the top of the turntable 42, four harness positioning rods 44 are arranged at intervals in a straight line on the cross support frame 43, a ring beam 45 is provided at the distal end of the cross support frame 43, and a support plate 46 is provided at the bottom of the ring beam 45 and the cross support frame 43, and the support plate 46 is nested with the turntable 42. The bottom of 6 is provided with a plurality of connecting plates 47 radially connected to the turntable 42, the distal end of the connecting plate 47 is provided with an anti-overturning leg 48, and the table 2 is provided with a circular track 5 for rotating the anti-overturning leg 48. The top of the frame 1 is provided with an anti-swing component 6 that is horizontally matched with the square tube. The anti-swing component 6 includes a guide wheel 61 that can slide left and right, and the guide wheel 61 is provided with a wheel groove for sliding the wiring harness. The corner position of the frame 1 is provided with an anti-collision column 7, and the side of the anti-collision column 7 is a cylindrical surface.

[0022] Specifically, the central axis 41 is coaxially connected to the shaft end of the drive mechanism, and a turntable 42 is fixed to the top of the central axis 41. The turntable 42 provides a rotational support base for the cross support frame 43, the ring beam 45, the support plate 46, and the wire harness positioning rods 44. The wire harness positioning rods 44 allow the head end of the wire harness to be wound in an S-shaped trajectory. The integrated wire harness is positioned by the S-shaped winding, and the subsequent wire harness is wound around the two outermost wire harness positioning rods 44 through the continuous rotation of the rotating support assembly 4. The top of the entire frame 1 adopts an open design, which facilitates the removal and placement of wire harnesses from the rotating support assembly 4. In particular, the support plate 46 and anti-overturning legs 48 in this device provide a larger support span for the support frame. In addition, the anti-overturning legs 48 cooperate with the circular track 5 to effectively improve the rotational stability of the rotating support. It also increases the support gap between the ring beam 45 and the table 2 to a certain extent, preventing the end structure of the wire harness from getting stuck in the equipment and affecting the bundling efficiency.

[0023] Furthermore, during the process of the wire harness being wound and bundled by the rotating support assembly 4, the anti-swing assembly 6 guides the free end of the wire harness to prevent the free end of the wire harness from swinging significantly with the rotating support assembly 4 and causing unnecessary hooking, which is beneficial for improving bundling efficiency and ensuring the integrity and quality of the product. The anti-collision performance of the equipment can be improved by providing anti-collision columns 7 at the corners of the frame 1. Therefore, the present device has the characteristics of simple structure, good anti-collision performance, relatively open operating range, easy access to the wire harness, and strong practicality. For the wire harness bundled by this device, it can be simply removed and bundled manually.

[0024] In order to improve the synchronous rotation performance of the support plate 46 and the turntable 42, the present invention is provided with four fan-shaped holes 421 on the side of the turntable 42. The fan-shaped holes 421 are plugged into one end of the connecting plate 47. The top of the turntable 42 is provided with fixing screws that pass through the fan-shaped holes 421 from top to bottom. The fixing screws connect the turntable 42 and the connecting plate 47. The connecting plate 47 and the support plate 46 are connected by through-plate screws 49. In this way, the support plate 46 can establish a synchronous transmission relationship with the turntable 42 through the connecting plate 47, and can rotate synchronously with the cross support frame 43 and the ring beam 45, thereby ensuring its support effect on the cross support frame 43, the ring beam 45 and the wiring harness.

[0025] In order to improve the utilization rate of the anti-swing assembly 6, the anti-swing assembly 6 provided by the present invention includes two movable tubes 62 nested with the square tube, a plurality of horizontally spaced jacks 63 are provided on the movable tubes 62, an anti-swing shaft 64 is provided between the two movable tubes 62 and matched with the jacks 63, the anti-swing shaft 64 is provided with two clamping sleeves 65 threadedly connected thereto, a guide wheel 61 is provided between the clamping sleeves 65, and a floating spring 66 is provided between the clamping sleeve 65 and the guide wheel 61. In this way, while the positioning end of the wire harness is subjected to the traction force of the driving mechanism, its free end can gradually move up to the rotating support assembly 4 along the wheel groove of the guide wheel 61, and while its free end is swinging, the floating spring 66 can balance the guide wheel 61, thereby reducing the swing amplitude of the free end of the wire harness. In addition, the operator's restraint on the wire harness can effectively ensure the efficiency of bundling the wire harness.

[0026] Furthermore, the movable tube 62 provided by the present invention provides multiple insertion holes for the anti-swing shaft 64 to be inserted, and a plug 67 is provided at the end of the movable tube 62 away from the frame 1, and a rotating pull ring 68 is provided on the plug 67. By pulling the rotating pull ring 68, the actual insertion length of the movable tube 62 and the square tube can be controlled, and the ground angle of the anti-swing shaft 64 and the wire harness being bundled can be controlled, which is conducive to ensuring smooth bundling.

[0027] To improve the coordination between the anti-overturning leg 48 and the annular track 5, the anti-overturning leg 48 provided in the present invention includes a column 481, a circular light plate 482 disposed at the bottom of the column 481, and an annular light groove 51 provided on the annular track 5 for rotationally cooperating with the circular light plate 482. Both the circular light plate and the annular light groove are polished to reduce friction, and the walls of the annular light groove act as a radial limit for the anti-overturning leg 48, thereby ensuring the balance of the entire rotating support assembly 4.

[0028] To improve the practicality of the anti-collision column 7, the anti-collision column 7 provided by the utility model is provided with a triangular prism groove that matches the corners of the frame 1. The top of the anti-collision column 7 is provided with a bolt connected to the table 2. The side of the anti-collision column 7 is provided with multiple warning light strips 71 spaced apart vertically. The warning light strips provide a warning function, and the anti-collision column 7 adopts an elastic rubber structure to prevent workers passing by or working on the frame 1 from colliding violently.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
