Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of wiring harness processing, and particularly relates to a wiring harness tape winding machine. BACKGROUND

[0002] The wiring harness or wiring of a vehicle is a core component for conducting electricity and transmitting signals of the vehicle, and is prone to wear and tear to cause interruption of the wiring harness and further cause failure of the vehicle if working in a vibrating environment for a long time. Therefore, it is necessary to wrap the wiring harness with tape from the safety and neatness perspectives. The wiring harness is pre-assembled, in which cables are arranged with correct wiring length and configuration and are constrained together by using a strap, a clamp, a cable tie or a conduit. Terminals of the cables are provided with connector elements for electrical connection to associated vehicle components. The wiring harness is also provided with body clamps at different positions along branches thereof for mechanically connecting the cable bundle to various structures in the vehicle.

[0003] A wiring harness tape winding device is disclosed in Chinese Patent No. CN117672629A, entitled "Wiring harness tape mounting device". However, the device uses synchronous belt transmission, and the gap of the winding device and the gap of the rack cannot be aligned after multiple uses, which often needs to be adjusted manually. Manual adjustment usually has two methods. One is to directly rotate the rotating assembly by force, which is fast but the synchronous belt is more likely to slip. The other way is to disassemble the transmission wheel, which is not only troublesome but also time-consuming. UTILITY MODEL CONTENTS

[0004] In view of the above prior art, the utility model aims to provide a wiring harness tape winding machine with controllable rotation angle.

[0005] The technical solution of the utility model is as follows: a wiring harness tape winding machine, comprising a driving gear, a superior arc gear and an inferior arc gear. The superior arc gear has a C-shaped main structure, i.e. a first gap. The superior arc gear is engaged with the driving gear. The inferior arc gear is coaxially arranged adjacent to the superior arc gear. The inferior arc gear can rotate relative to the superior arc gear to have a first relative position and a second relative position with the superior arc gear. The first relative position is a wiring harness taking and placing position. The second relative position is a continuous transmission position, so that the driving gear can be engaged with at least one of the inferior arc gear or the superior arc gear.

[0006] The beneficial effect of such design is that the first gap and the second gap of the C-shaped limiting ring and the optimal arc gear can be accurately controlled by the motor, avoiding deviation caused by slipping during transmission, and there is no need to set an extra position sensor, so that the wire harness can be quickly taken out after being wrapped with adhesive tape, and the poor arc gear can be moved to the first relative position, the poor arc gear can be provided with a spring and quickly reset through the spring, which is more convenient and fast, and the locking structure arranged at the second relative position makes the transmission more stable.

[0007] Further, the wire harness adhesive tape wrapping machine comprises a rack, a driving motor, a tape wheel, a C-shaped limiting ring and a limiting wheel, the driving motor and the limiting wheel are installed to the rack, the limiting wheel limits the axial position of the C-shaped limiting ring and ensures that the C-shaped limiting ring can rotate circumferentially, the C-shaped limiting ring is fixed together with the optimal arc gear or adopts an integrated structure, the C-shaped limiting ring is provided with a second gap and is correspondingly arranged at the position of the first gap, the wire harness can enter the inner circumference of the optimal arc gear from the first gap and the second gap when the poor arc gear and the optimal arc gear are at the first relative position, the driving gear is driven by the driving motor, the tape wheel can rotate by itself and the tape wheel can rotate synchronously with the optimal arc gear, the poor arc gear is located at the position of the first gap and the second gap when the poor arc gear and the optimal arc gear are at the second relative position, so that the driving gear can be disengaged from the optimal arc gear and the poor arc gear to realize transmission through the poor arc gear when the optimal arc gear rotates to the position of the first gap relative to the driving gear. The limiting wheel is arranged at least four circumferentially on the outer circumference or the inner circumference of the C-shaped limiting ring, so that the C-shaped limiting ring rotates to any position and at least abuts against three limiting wheels, the included angle between any two interval-arranged limiting wheels in the circumferential direction is less than 180 degrees, the driving gear is arranged at a position away from the limiting wheel when the limiting wheel is arranged on the outer circumference of the C-shaped limiting ring, so that the sum of the distances between the driving gear and each limiting wheel is larger, the driving gear is arranged at a position close to the limiting wheel when the limiting wheel is arranged on the inner circumference of the C-shaped limiting ring, so that the sum of the distances between the driving gear and each limiting wheel is smaller. Since the C-shaped limiting ring has the second gap, only three limiting wheels abut against the C-shaped limiting ring when the second gap is directly opposite one limiting wheel. At this time, if the two limiting wheels are at a position of 180 degrees and the remaining one limiting wheel is at the same side of the driving gear, the C-shaped limiting ring can move towards the gap position, so that the position of the C-shaped limiting ring is very unstable. However, the included angle between the two interval-arranged limiting wheels in the circumferential direction of the technical solution of the present application is less than 180 degrees, and the driving gear is arranged away from the limiting wheel when the limiting wheel is arranged on the outer circumference of the C-shaped limiting ring, so that such a situation can be avoided. The driving gear is arranged close to the limiting wheel when the limiting wheel is arranged on the inner circumference of the C-shaped limiting ring, so that such a situation can also be avoided. The four positioning wheels and the synchronous wheel in the drawings of “CN117672629A” cannot be actually implemented, the sum of the positioning wheels and the synchronous wheel must be more than 4, and the technical solution of the present application only needs four limiting wheels to achieve the same effect.

[0008] Further, the tooth circumferential arrangement range of the optimal arc gear is more than 180 degrees, the tooth arrangement range of the poor arc gear is less than 180 degrees but more than the first gap position tooth arrangement angle, so that the design of the transmission is facilitated, the first gap of the optimal arc gear is larger, the installation of the wire harness for the wrapping of the adhesive tape is facilitated, but the transmission structure and the auxiliary structure design are more complex, the first gap is smaller, the transmission structure and the auxiliary structure design are easier, and the gap is generally designed to be about 3 cm wide.

[0009] Further, the limiting wheel is fixed to the rack through a bearing to enable the limiting wheel to rotate freely, so that the C-shaped limiting wheel has smaller rotating resistance and can rotate stably.

[0010] Further, the limiting wheel is provided with a limiting groove or a limiting convex ring matched with the corresponding position of the C-shaped limiting ring to enable the limiting wheel to limit the axial position of the C-shaped limiting ring, so that stable rotation is realized through a simple structure.

[0011] Further, the thickness of the driving gear is equal to the sum of the optimal arc gear and the poor arc gear, so that the driving gear can be stably meshed with the optimal arc gear and the poor arc gear.

[0012] Further, the C-shaped limiting ring is provided with an annular groove, and the poor arc gear is installed in the annular groove in a rotatable manner relative to the C-shaped limiting ring, so that the assembly of various parts is facilitated.

[0013] Further, the C-shaped limiting ring is provided with an elastic locking pin, the locking end of the poor arc gear is provided with an inclined surface and a locking hole, and when the poor arc gear rotates from the first relative position to the second relative position, the inclined surface pushes the elastic locking pin to move and is inserted into the locking hole when the elastic locking pin is aligned with the locking hole to realize locking, so that the locking is convenient and the poor arc gear can be locked by rotating.

[0014] Further, the C-shaped limiting ring and / or the optimal arc gear is provided with an arc-shaped groove, and the poor arc gear is provided with a push rod, and the push rod is located in the arc-shaped groove, and the poor arc gear is rotated through the push rod.

[0015] Further, the C-shaped limiting ring is provided with guide wheels on the two sides in the axial direction, and the guide wheels are provided with guide grooves, so that the main wire harness of the electric vehicle lamp is conveniently fixed. BRIEF DESCRIPTION OF DRAWINGS
