Description

Technical Field

[0001] This utility model relates to a wire harness tape wrapping machine, specifically a wire harness tape wrapping machine with a cutting structure, belonging to the field of wrapping machine technology. Background Technology

[0002] In the wire harness production process, in order to mark or protect the wire harness, a wire harness tape wrapping machine is used to wrap tape around the cable and other objects. The wire harness tape wrapping machine can replace manual wrapping, and wraps the tape evenly on the surface of the cable harness, ensuring that the tape is flat and improving the wrapping efficiency and accuracy of the cable harness.

[0003] Wire harness tape wrapping machines are typically equipped with a moving component, a clamping component, and a flat wrapping component. After the cable harness is clamped by the clamp, the flat wrapping component wraps and flat wraps the clamped cable harness. Generally, it is inconvenient to adjust the length of the flat-wrapped cable harness.

[0004] A search revealed that in the prior art, such as the wire harness winding and wrapping machine disclosed in announcement number CN218849164U, there is a wire harness winding and wrapping device and a base plate. The wire harness winding and wrapping device is movably connected to the top of the base plate. The wire harness winding and wrapping device includes a drive unit and a winding unit. The drive unit is movably connected to the top of the base plate. By providing a rotator and a movable rotating block, it can be adjusted according to the length of the wire harness, and can adapt to wire harnesses of various lengths, thus having a wide range of applications.

[0005] In actual use, after the above-mentioned technical solution is wrapped flat, the tape needs to be cut. Currently, when cutting the tape, most workers directly hold a knife to cut it. When handling the blade, if the hand touches the blade, it is easy to get injured, which is not very safe. Utility Model Content

[0006] This invention provides a wire harness tape wrapping machine with a cutting structure to solve the problem of low safety during the wire harness wrapping process, which requires manual cutting of the tape.

[0007] The present invention achieves the above objectives through the following technical solution: a wire harness tape wrapping machine with a cutting structure, comprising a wrapping machine base plate, and a tape placement assembly, a cutting assembly and a wire harness placement assembly located on the top of the wrapping machine base plate;

[0008] The cutting assembly includes a slide rod fixed to the top of the base plate of the winding machine via a support frame. A movable bracket is fitted around the slide rod. A lead screw motor is fixed to the top of the movable bracket via external bolts. A cutting lead screw is fixedly connected to the power output end of the lead screw motor. A blade bracket is connected to the outside of the cutting lead screw via a lead screw nut. A cutting blade is installed inside the blade bracket via screws.

[0009] As a further embodiment of this utility model: a wire harness body is movably arranged between the wire harness placement components. The wire harness placement components include a movable base fixed to the top of the winding machine base plate, and two sets of adjustment brackets are slidably installed inside the movable base.

[0010] As a further embodiment of this utility model: the inside of the adjusting bracket is rotatably connected to a transmission rod via a bearing, and one end of the transmission rod is fixedly connected to the power output end of a transmission motor. The bottom of the adjusting bracket is connected to a double-acting screw via a screw nut, and a movable base is installed on the outside of the double-acting screw. A guide groove is provided at the connection between the movable base and the adjusting bracket.

[0011] As a further embodiment of this utility model: a fixed clamping head is fixedly provided at the other end of the transmission rod, and a movable clamping head is symmetrically provided on one side of the fixed clamping head, and the movable clamping head is slidably connected to the transmission rod.

[0012] As a further embodiment of this utility model: a connecting screw is threaded between the movable clamping head and the fixed clamping head, and a clamping plate is elastically connected to the inner side of the movable clamping head and the fixed clamping head.

[0013] As a further improvement of this utility model: a clamping spring is fixedly provided on one side of the clamping plate, and a telescopic rod is passed through the inside of the clamping spring.

[0014] As a further embodiment of this utility model: the tape placement assembly includes a support rod sleeved on the outside of the slide bar, and a tape placement base is fixedly provided at the end of the support rod. A movable screw is installed inside the tape placement base through a screw nut.

[0015] The beneficial effects of this utility model are:

[0016] After the winding is completed, the lead screw motor can be started by the cutting component. The lead screw motor drives the cutting lead screw to rotate, which causes the cutting blade to move downward to cut the tape. The cutting blade can also move synchronously to the end of the wire harness under the action of the adjustment bracket, so that the position of the cutting blade can be adjusted according to the length of the wire harness of different lengths. The tape can be cut without holding the cutting blade.

[0017] With the help of the wire harness placement assembly, the distance between the adjustment brackets can be adjusted according to the length of the wire harness body under the action of the bidirectional lead screw. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] like Figures 1 to 5 As shown, a wire harness tape wrapping machine with a cutting structure includes a wrapping machine base plate 1, and a tape placement assembly 2, a cutting assembly 4 and a wire harness placement assembly 5 located on top of the wrapping machine base plate 1.

[0026] The cutting assembly 4 includes a slide rod 401 fixed to the top of the base plate 1 of the winding machine via a support frame. A movable bracket 402 is sleeved on the outside of the slide rod 401. A lead screw motor 403 is fixedly mounted on the top of the movable bracket 402 by external bolts. A cutting lead screw 404 is fixedly connected to the power output end of the lead screw motor 403. A blade bracket 405 is connected to the outside of the cutting lead screw 404 via a lead screw nut. A cutting blade 406 is installed inside the blade bracket 405 by screws. When the winding is finished, the lead screw motor 403 can be started. The lead screw motor 403 drives the cutting lead screw 404 to rotate, thereby causing the cutting blade 406 to move downward and cut the tape. Example 2

[0027] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0028] A wire harness body 3 is movably disposed between the wire harness placement components 5. The wire harness placement components 5 include a movable base 512 fixed to the top of the winding machine base plate 1, and two sets of adjusting brackets 502 are slidably installed inside the movable base 512. The adjusting brackets 502 can slide on the movable base 512 and can be adjusted according to the length of the wire harness body 3.

[0029] The adjustment bracket 502 is internally connected to a transmission rod 501 via a bearing, and one end of the transmission rod 501 is fixedly connected to the power output end of the transmission motor 503. The bottom of the adjustment bracket 502 is connected to a double-acting screw 504 via a screw nut, and a movable base 512 is mounted on the outside of the double-acting screw 504. A guide groove 511 is provided at the connection between the movable base 512 and the adjustment bracket 502. The guide groove 511 guides the movement direction of the adjustment bracket 502. The double-acting screw 504 rotates under the action of the transmission motor 503, thereby driving the adjustment bracket 502 to move.

[0030] A fixed clamping head 506 is fixedly provided at the other end of the transmission rod 501, and a movable clamping head 505 is symmetrically provided on one side of the fixed clamping head 506. The movable clamping head 505 is slidably connected to the transmission rod 501. The transmission rod 501 can drive the fixed clamping head 506 to rotate, thereby driving the wire harness body 3 placed inside the fixed clamping head 506 to rotate synchronously.

[0031] A connecting screw 510 is threaded between the movable clamping head 505 and the fixed clamping head 506, and a clamping plate 507 is elastically connected to the inner side of the movable clamping head 505 and the fixed clamping head 506. Rotating the connecting screw 510 can move the movable clamping head 505 away from the fixed clamping head 506, making it convenient for the wire harness body 3 to be placed between the movable clamping head 505 and the fixed clamping head 506.

[0032] A clamping spring 508 is fixedly provided on one side of the clamping plate 507, and a telescopic rod 509 is inserted inside the clamping spring 508. When the clamping plate 507 clamps the wire harness body 3, it can squeeze the clamping spring 508 and the telescopic rod 509 inward, so that the telescopic rod 509 is compressed inward. By utilizing the elasticity of the clamping spring 508, the wire harness body 3 is clamped in the opposite direction. Example 3

[0033] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0034] The tape placement assembly 2 includes a support rod 203 sleeved on the outside of the slide rod 401, and a tape placement base 202 is fixedly installed at the end of the support rod 203. A movable screw 201 is installed inside the tape placement base 202 through a screw nut. The width of the tape placement base 202 is greater than the width of the support rod 203. One side of the tape placement base 202 is used to place tape and can be used to wrap the wire harness body 3. The support rod 203 can slide on the slide rod 401 to guide the movement direction of the tape placement base 202. When the movable screw 201 rotates under the drive of the motor, it can drive the tape placement base 202 to move back and forth.

[0035] Working principle: When using the wire harness tape wrapping machine with a cutting structure, the bidirectional lead screw 504 rotates under the action of the drive motor 503, thereby driving the adjusting bracket 502 to move. The guide groove 511 guides the movement direction of the adjusting bracket 502. The bidirectional lead screw 504 rotates under the action of the drive motor 503, thereby driving the adjusting bracket 502 to adjust according to the length of the wire harness body 3. The wire harness body 3 is placed between the movable clamping head 505 and the fixed clamping head 506. Rotating the connecting screw 510 makes the movable clamping head 505 and the fixed clamping head 506 move closer to each other, while simultaneously squeezing the clamping spring 508 and the telescopic rod 509 inward. This causes the telescopic rod 509 to compress inward. Utilizing the elasticity of the clamping spring 508, the wire harness body 3 is clamped in the opposite direction. Subsequently, the drive motor 503 drives the drive rod 501 to rotate. 501 can drive the fixed clamping head 506 to rotate, so that the wire harness body 3 rotates synchronously. The tape installed on the tape placement base 202 is unrolled and wrapped around the outside of the wire harness body 3. Since the moving bracket 402 moves with the movement of the adjusting bracket 502, when the tape placement base 202 drives the support rod 203 to move to the direction close to the adjusting bracket 502, the wire harness body 3 is finished winding. At this time, the tape is close to the cutting component 4, and the lead screw motor 403 is started. The lead screw motor 403 drives the cutting lead screw 404 to rotate, so that the cutting blade 406 moves downward to cut the tape. In order to facilitate the cutting of the tape, the tape placement base 202 is inclined to the wire harness body 3 and is located above the slide rod 401. When the cutting blade 406 is at the top, it does not contact the tape. As the cutting blade 406 descends, the tape can be cut.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
