[0002] In the electrical wiring, aerospace, automotive, home appliance, and medical fields, wire harnesses require wrapping adhesive tape around their outer periphery. Currently, this is mainly done manually by holding the wire harness and inserting it into an adhesive tape wrapping machine. The machine wraps the harness while the operator moves it to complete the tape wrapping. However, the wrapping mechanism rotates at high speed during operation, posing a risk of hand injury to the operator who may come into contact with the mechanism while moving the wire harness. Utility Model Content

[0003] The purpose of this invention is to provide a wire harness tape wrapping machine to ensure the safety of operators during the wire harness wrapping process.

[0004] A wire harness tape wrapping machine includes: a base, a protective cover, a power control mechanism, a drive mechanism, and a wrapping mechanism;

[0005] The base has an installation cavity with an opening at the top. The protective cover is detachably installed above the opening of the base. A through hole is formed between the bottom end of the protective cover and the top end of the base, allowing the wire bundle to be wrapped to pass through on both sides. The drive mechanism is fixedly connected to one side of the base. The winding mechanism is rotatably connected to the base and located in the installation cavity. The drive end of the drive mechanism is connected to the winding mechanism and can drive the winding mechanism to rotate around the wire bundle to be wrapped for wrapping.

[0006] The power control mechanism is installed in the base body and has a trigger switch. The trigger switch is fixedly connected to the inner wall of the base body. The trigger switch can switch between an on state and an off state. When the trigger switch is in the on state, the power control mechanism is electrically connected to the drive mechanism. When the trigger switch is in the off state, the power control mechanism is electrically disconnected from the drive mechanism.

[0007] A triggering part is provided on the inner wall of the protective cover at a position corresponding to the triggering switch. When the protective cover is closed on the base, the triggering switch is in the open state. When the protective cover is removed from the base, the triggering switch switches to the off state.

[0008] Preferably, the trigger switch includes: a switch body, a spring, and a roller. The switch body is fixedly connected to the base. One end of the spring is fixedly connected to the switch body. The roller is rotatably connected to the other end of the spring. The trigger part cooperates with the roller to control the switching of the trigger switch between the open state and the closed state.

[0009] Preferably, one end of the protective cover is rotatably connected to the base.

[0010] Preferably, the wire harness tape wrapping machine further includes a base plate, the seat is fixedly connected to the top of the base plate, and the drive mechanism is fixedly connected to the top of the base plate.

[0011] Preferably, the device further includes two support frames, which are respectively spaced apart on the left and right sides of the base body. The bottom end of each support frame is fixedly connected to the base plate, and the top end of each support frame has a support position for supporting the wire bundle to be wrapped.

[0012] Preferably, the support position is an arc-shaped recess formed at the top of the support frame.

[0013] Preferably, the winding mechanism includes a positioning part, which has positioning holes extending through the left and right sides for the wire bundle to be wound to pass through, and a plastic insulating layer is provided along the inner peripheral wall of the positioning hole.

[0014] Preferably, the positioning part includes a metal inner layer, and the outer periphery of the metal inner layer is wrapped with the plastic insulating layer.

[0015] Preferably, the outer periphery of the positioning part is provided with an adhesive tape mounting assembly for mounting adhesive tape, and the positioning part and the side located with the adhesive tape mounting assembly are provided with a through groove communicating with the positioning hole, so that the adhesive tape passes through the through groove and enters the positioning hole.

[0016] Preferably, the positioning part is provided with a blade, and the blade is located on the outer periphery of the side opposite to the positioning hole and the through groove. The left and right sides of the base are provided with operation holes for the adhesive wire bundle to be wrapped to be separated from the adhesive tape at the blade. The through hole communicates with the operation hole.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] Only when the protective cover is closed on the base body and the trigger switch is in the open state can the winding mechanism be driven by the drive mechanism to wind the wire harness to be wrapped. At this time, the operator can safely feed the wire harness into the base body under the joint protection of the protective cover and the base body. When the protective cover is not closed on the base body, the electrical connection between the power control mechanism and the drive mechanism is disconnected, and the winding mechanism is in a stopped state and cannot rotate. This effectively prevents the operator from working under insufficient protection measures and enhances the safety of the winding work. Attached Figure Description

[0029] Combination Figure 1-5 As shown, a wire harness tape wrapping machine includes a base 1, a protective cover 2, a power control mechanism 3, a drive mechanism 4, and a wrapping mechanism 5. The base 1 has a mounting cavity 11 with an opening 111 at the top. The protective cover 2 is detachably mounted above the opening 111 of the base 1. A through hole 12 is formed between the bottom end of the protective cover 2 and the top end of the base 1, extending through both sides for the wire harness 8 to be wrapped. The drive mechanism 4 is fixedly connected to one side of the base 1. The wrapping mechanism 5 is rotatably connected to the base 1 and located within the mounting cavity 11. The drive end of the drive mechanism 4 is connected to the wrapping mechanism 5, enabling the wrapping mechanism 5 to rotate around the wire harness 8 to perform tape wrapping. The power control mechanism 3 is mounted on the base 1. Inside the body 1, the power control mechanism 3 has a trigger switch 31, which is fixedly connected to the inner wall of the body 1. The trigger switch 31 can switch between an on state and an off state. When the trigger switch 31 is in the on state, the power control mechanism 3 is electrically connected to the drive mechanism 4. When the trigger switch 31 is in the off state, the electrical connection between the power control mechanism 3 and the drive mechanism 4 is disconnected. The inner wall of the protective cover 2 is provided with a trigger part 21 at a position corresponding to the trigger switch 31. When the protective cover 2 is closed on the body 1, the trigger switch 31 is in the on state. When the protective cover 2 is removed from the body 1, the trigger switch 31 switches to the off state.

[0030] In this embodiment, the wire harness tape wrapping machine is also equipped with a master switch. Only when the protective cover 2 is placed above the base 1, that is, after the triggering part 21 activates the trigger switch 31 to make the control end electrically connected to the drive mechanism 4, and then the master switch is turned on, the drive mechanism 4 drives the wrapping mechanism 5 to wrap the wire harness 8 to be wrapped. When the master switch is turned on without the triggering part 21 activating the trigger switch 31, the drive mechanism 4 cannot work, thus avoiding the risk of the operator being injured by the rotating wrapping mechanism 5 when there is no protective cover 2. The process of using the wire harness tape wrapping machine of this application is as follows: Remove the protective cover 2 above the base 1, place the portion of the wire harness 8 to be wrapped into the wrapping mechanism 5, and first wrap the wire harness 8 with the tape on the wrapping mechanism 5 to half a turn to one turn. Then, cover the base 1 with the protective cover 2 to turn on the trigger switch 31. Hold the wire harness 8 with both hands on the left and right sides of the base 1 respectively. After turning on the main switch with your foot, the wrapping mechanism 5 rotates and wraps the tape around the outer circumference of the wire harness 8. The operator moves the wire harness 8 with both hands to feed it into the base 1 from right to left, and then sends the wrapped portion of the wire harness 8 out of the base 1. With the combined protection of the base 1 and the protective cover 2, the operator's hands will not enter the base 1. Using the wire harness tape wrapping machine of this application, the operator can safely complete the wrapping of the wire harness 8.

[0031] Furthermore, the trigger switch 31 includes: a switch body 311, a spring 312, and a roller 313. The switch body 311 is fixedly connected to the base 1. One end of the spring 312 is fixedly connected to the switch body 311. The roller 313 is rotatably connected to the other end of the spring 312. The trigger part 21 cooperates with the roller 313 to abut against each other, so as to control the switching of the trigger switch 31 between the open state and the closed state.

[0032] In this embodiment, when the protective cover 2 is removed, the end of the spring piece 312 connected to the roller 313 moves away from the switch body 311, and the roller 313 protrudes above the top of the base 1. When the protective cover 2 is placed over the base 1, the trigger part 21 contacts the top of the roller 313 and presses down, causing the spring piece 312 to deform towards the switch body 311, thereby triggering the switch 31 to the open state. For example, the switch body 311 is provided with a switch button. After the trigger part 21 contacts the top of the roller 313 and presses down, the spring piece 312 presses the switch button, thereby triggering the switch 31 to the open state. The roller 313 reduces the contact area between the trigger part 21 and the spring piece 312, enhancing the effect of pressing down on the spring piece 312 and ensuring that the closing of the protective cover 2 smoothly achieves electrical connection between the control terminal and the drive mechanism 4.

[0033] The protective cover 2 is detachably connected to the base 1 via a rotatable connection. Furthermore, one end of the protective cover 2 is rotatably connected to the base 1. When the protective cover 2 is rotated and closed over the base 1, the trigger part 21, through the roller 313, acts on the deformation of the spring piece 312 to activate the trigger switch 31, and the drive mechanism 4 connects the circuit. When the protective cover 2 is opened, the spring piece 312 returns to its original shape, the trigger switch 31 is deactivated, the drive mechanism 4 disconnects the circuit, and the protective cover 2 can rotate to one side of the base 1. This arrangement ensures that the drive mechanism 4 connects the circuit each time the protective cover 2 is closed over the base 1, avoiding a situation where the position of the trigger part 21 and the position of the trigger switch 31 do not match when the protective cover 2 is closed over the base 1, preventing the trigger switch 31 from being unable to open.

[0034] To further enhance the overall integrity of the equipment, a base plate 6 is also included. The base body 1 is fixedly connected to the top of the base plate 6, and the drive mechanism 4 is fixedly connected to the top of the base plate 6.

[0035] Furthermore, the wire harness tape wrapping machine also includes two support frames 7, which are respectively spaced apart on the left and right sides of the base body 1. The bottom end of the support frame 7 is fixedly connected to the base plate 6, and the top end of the support frame 7 has a support position 71 for supporting the wire harness 8 to be wrapped.

[0036] In this embodiment, the wire harness is started using an adhesive tape wrapping machine. When the wrapping mechanism 5 wraps the wire harness 8 to be wrapped, the operator holds the wire harness 8 and transmits it from right to left. The unwound portion of the wire harness 8 is placed on the right-side support frame 7, and the wrapped portion is placed on the left-side support frame 7. The operator only needs to transmit the wire harness 8 without specifically supporting it for the wrapping mechanism 5 to complete the wrapping, reducing operator hand fatigue. In the prior art, when relying solely on manual support of the wire harness 8, hand tremors can easily occur, resulting in uneven wrapping of the adhesive tape on the outer surface of the wire harness 8. With the support frame 7, the operator can more easily achieve uniform wrapping of the wire harness 8.

[0037] Furthermore, the support position 71 is an arc-shaped recess formed at the top of the support frame 7. The arc-shaped recess provides a certain limit to the wire harness 8 to be wrapped, while not scratching the wire harness 8 to be wrapped, effectively preventing the wire harness 8 to be wrapped from sliding out of the support frame 7 when placed on top of the support frame 7, thus ensuring the support effect of the support frame 7 on the wire harness 8 to be wrapped.

[0038] Furthermore, the winding mechanism 5 includes a positioning part 51, on which positioning holes 511 are provided through the left and right sides for the wire bundle 8 to be wound to pass through, and a plastic insulating layer 512 is provided along the inner peripheral wall of the positioning hole 511.

[0039] Before the drive mechanism 4 is powered on, the wire bundle 8 to be wrapped is placed inside the plastic insulation layer 512 for temporary support. When the drive mechanism 4 is powered on, the drive end of the drive mechanism 4 drives the plastic insulation layer 512 and the positioning part 51 to rotate around the wire bundle 8 as the axis to wrap the wire bundle. The operator moves the wire bundle 8 to complete the wrapping work around the outer periphery of the wire bundle 8.

[0040] Furthermore, the positioning part 51 includes a metal inner layer, and the outer periphery of the metal inner layer is wrapped with the plastic insulation layer 512. The wire bundle 8 to be wrapped is temporarily placed inside the plastic insulation layer 512, and is mainly supported by the metal inner layer. Compared with directly placing the wire bundle 8 to be wrapped inside the metal inner layer to complete the wrapping, reinforcing the plastic insulation layer 512 can effectively prevent the metal inner layer from scratching the surface of the wire bundle 8 under high-speed operation.

[0041] To facilitate the wrapping of the wire bundle 8 with the tape, the positioning part 51 is further provided with a tape mounting assembly for mounting the tape on its outer periphery. A through groove 515 communicating with the positioning hole 511 is provided on the positioning part 51 and on the side adjacent to the tape mounting assembly, allowing the tape to pass through the through groove 515 and enter the positioning hole 511. In this embodiment, before the driving mechanism 4 is powered on, the wire bundle 8 is placed in the positioning hole 511, specifically inside the plastic insulation layer 512. After the tape is mounted on the tape roll mounting assembly 514, it is passed through the through groove 515 and adhered to the outer periphery of the wire bundle 8, wrapping it for more than half a turn. After the driving mechanism 4 is powered on, the winding mechanism 5 begins to rotate, and the operator moves the wire bundle 8, allowing the tape to continuously wrap around the outer periphery of the wire bundle 8.

[0042] In some embodiments, when the plastic insulating layer 512 has a large range and blocks the connection between the through groove 515 and the positioning hole 511, a through groove 5121 is provided on the side of the plastic insulating layer 512 near the through groove 515 so that the adhesive tape passes through the through groove 515 and the through groove 5121 to enter the positioning hole 511 and connect with the wire bundle 8 to be wrapped.

[0043] Furthermore, the positioning part 51 is provided with a blade 513, and the blade 513 is located on the outer periphery of the side opposite to the positioning hole 511 and the through groove 515. The left and right sides of the base body 1 are provided with operation holes 13 for the adhesive wire bundle 8 to be wrapped to be separated from the adhesive tape at the blade 513. The through hole 12 is connected to the operation hole 13.

[0044] In this embodiment, after the wire harness 8 to be wrapped is completed, the power supply to the drive mechanism 4 is disconnected. The connection point between the wire harness 8 and the tape is moved to the blade 513 to cut the tape, facilitating the removal of the wire harness 8 from the tape wrapping machine after wrapping. Corresponding to the tape cutting operation, the operating hole 13 ensures sufficient space for the operator to hold the wire harness 8 outside the base 1 and move it to the blade 513 to cut the tape. Controlling the size of the through hole 12 and the operating hole 13 prevents the operator from accidentally inserting their hand into the base 1, reducing operational risks.
