[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added, etc., and the wiring harness is bundled to form a component connecting the circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The automotive body wiring harness connects the entire body and is generally H-shaped. Wire harness rubber coating means that the surface of the wires in the wire harness needs to be wrapped with tape to fix the wires in the wire harness and play an insulating and protective role. The wire clamping part of the existing glue wrapping machine will cause friction on the surface of the wire harness when the glue wrapping machine rotates to wrap the glue, which will not only cause wear to the surface of the wire harness, but also cause wear to the wire clamping part of the glue wrapping machine. After a period of use, the wire clamping part of the glue wrapping machine needs to be replaced, resulting in an increase in the use cost of the glue wrapping machine; the existing glue wrapping machine uses a blade to cut off the tape after completing the glue wrapping of the wire harness, but the blade is not covered and may cut the user's hand.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] In the drawings, the same reference numerals all refer to the same components.

[0025] like Figure 1-6 As shown, the utility model provides a handheld automatic wire harness gluing machine, comprising a transmission box 1, a driving motor 2, a handheld part 3 and a rotating part 4, the driving motor 2 is arranged on the handheld part 3, and its output shaft is arranged away from the handheld part 3, the transmission box 1 is arranged on the driving motor 2, and is transmission-connected to the output shaft of the driving motor 2, the rotating part 4 is rotatably arranged in the transmission box 1, and is transmission-connected to the transmission box 1, and the rotating part 4 is provided with a wire clamping part 5 for placing the wire harness and a mounting part 6 for mounting the tape.

[0026] In this embodiment, the hand-held portion 3 is used for the user to hold. When in use, the user holds the hand-held portion 3, and installs the tape on the mounting portion 6, pulls out the tape so that the tape enters the wire clamping portion 5, and then puts the wire harness with glue into the wire clamping portion 5, so that the end of the tape adheres to the surface of the wire harness, and then starts the drive motor 2 using the prior art, the drive motor 2 drives the gear in the transmission box 1 and then drives the rotating portion 4 and the wire clamping portion 5 and the mounting portion 6 on the rotating portion 4 to rotate, and the user then translates the hand-held portion 3 according to the speed of glue wrapping to wrap the wire harness from one end to the other end;

[0027] The transmission box 1 is a reduction box using the prior art.

[0028] Furthermore, the rotating part 4 includes a C-shaped gear 41 and a mounting plate 42. The C-shaped gear 41 is embedded in the transmission box 1, and the teeth on its outer periphery are meshed and connected with the gears in the transmission box 1. The mounting plate 42 is arranged on the side wall of the C-shaped gear 41 and is adapted to the C-shaped gear 41.

[0029] In this embodiment, the driving motor 2 drives the gears in the transmission box 1 to rotate, and then drives the C-shaped gear 41 to rotate through the gears in the transmission box 1, and drives the mounting plate 42 disposed on the surface of the C-shaped gear to rotate.

[0030] Furthermore, the wire clamping part 5 includes a U-shaped clamping groove 51, which is embedded in the recesses of the C-shaped gear 41 and the mounting plate 42. The top, bottom and inner wall of the U-shaped clamping groove 51 are provided with a first slide groove 52. A roller 53 is installed in each first slide groove 52 through a rotating seat. The rotating seats of the rollers 53 are connected to the corresponding first slide grooves 52 through springs. The U-shaped clamping groove 51 is provided with a groove for the tape to pass through.

[0031] In this embodiment, the U-shaped slot 51 is fixed in the recessed part of the C-shaped gear 41 and the mounting plate 42, and one end of the U-shaped slot 51 away from the transmission case 1 extends to the outside of the mounting plate 42, and the U-shaped slot 51 is used to place the wiring harness;

[0032] The top inner wall, bottom inner wall and inner side wall of the U-shaped slot 51 are all provided with a first slide groove 52 for installing a rotating seat. The bottom end of the rotating seat is connected to the bottom end of the first slide groove 52 by a spring. A roller 53 is rotatably connected between each rotating seat. When the roller 53 is subjected to pressure, the rotating seat can shrink into the corresponding first slide groove 52. When the roller 53 is not subjected to force, the corresponding rotating seat is pushed out by the spring. This structure can not only adapt to wire harnesses with a certain range of diameters, but also can contact the surface of the wire harness through the roller 53, thereby reducing the wear caused by direct friction with the surface of the wire harness in the traditional way.

[0033] Furthermore, a support 7 is provided at the lower end of the U-shaped slot 51, a cutter 71 is provided at the top of the support 7, and two second slide grooves 72 are also provided at the top of the support 7. A baffle 73 is movably provided in each second slide groove 72, and the two baffles 73 are respectively located on both sides of the cutter 71, and each baffle 73 is connected to the corresponding second slide groove 72 by a spring.

[0034] In this embodiment, the support 7 is used to install the cutter 71. There are two retractable baffles 73 on both sides of the cutter 71. When the baffles 73 are not under force, they can block the cutter 71, thereby reducing the possibility of the cutter cutting the user. When the cutter 71 is used to cut the tape, the tape applies pressure to the baffles, causing the baffles 73 to shrink into the corresponding second slide groove 72. After the baffles 73 are no longer under force, the baffles 73 are pushed out and reset by the spring.

[0035] Furthermore, the mounting portion 6 includes a connecting plate 61, which is arranged on the top of the mounting disk 42. A center column 62 is provided at one end of the connecting plate 61 away from the transmission box 1. A plurality of spring support rods 63 are provided on the outer periphery of the center column 62. An arc plate 64 is provided at the end of each spring support rod 63. Each arc plate 64 has an extension portion 65 facing the center column 62 at one end away from the transmission box 1. A guide roller 8 for guiding the tape is rotatably provided on the mounting disk 42.

[0036] The tape installation part of the existing rubber wrapping machine is connected to the tape by friction damping. After a period of use, the tape installation part of the rubber wrapping machine will also wear out, resulting in the tape being unable to be stably installed on the tape installation part. In this embodiment, the central column 62 on the connecting plate 61 plays a supporting role. When installing the tape, the inner circle of the tape contacts the extension part 65, and the extension part 65 can facilitate the inner circle of the tape to slide into the annular structure composed of multiple arc plates 64. In the above process, the inner circle of the tape applies pressure to the arc plate 64, and the arc plate 64 squeezes the spring support rod 63 using the prior art to contract, so that the annular structure composed of multiple arc plates 64 becomes a diameter compatible with the inner circle of the tape. When the tape is installed on the arc plate 64, the spring support rod 63 continues to apply force to the arc plate 64, so that the tape can be installed tighter and not easy to fall off; after removing the tape, the spring support rod 63 resets the corresponding arc plate 64.

[0037] Furthermore, a counterweight 9 is provided at the bottom of the mounting plate 42 .

[0038] In this embodiment, the counterweight block 9 can ensure that the rubber encapsulating machine is in balance when the rotating part 4 is working.

[0039] Furthermore, a suspension member 10 is provided between the handle 3 and the transmission box 1 .

[0040] In this embodiment, the suspension member 10 can facilitate the lagging machine to be suspended on the coil spring balancer.

[0041] The utility model discloses a hand-held automatic wire harness glue wrapping machine. When the glue wrapping machine is used for glue wrapping, the roller in the U-shaped clamping groove contacts the surface of the wire harness, and the friction with the surface of the wire harness can be reduced by the roller, so as to prevent the wear of the surface of the wire harness, and the service life of the wire clamping part can be extended, so as to reduce the use cost of the glue wrapping machine; the cutter can be shielded by two baffles to reduce the possibility of the cutter cutting the worker, and when the cutter cuts the tape, the baffle will shrink due to the pressure of the tape, so as to facilitate the cutter to cut the tape.

[0042] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
