Description

An automatic wire tape winding and finishing device Technical Field

[0001] This application relates to the field of mechanical automation technology, specifically to an automatic winding and finishing device for wire tape. Background Technology

[0002] Automotive wiring harnesses have terminals at one end and two wires leading out from the terminals at the other end. These two wires need to be wrapped with tape to form a wiring harness. In the traditional method, the terminal and the end of the wiring harness are often held manually and moved inside a wrapping machine. During the movement, the wrapping machine rotates around the wiring harness with tape to wrap the tape around it. Because the speed of the manual movement can vary at any time, it will lead to uneven overlap of the wiring harness during the wrapping process. When the movement is slow, there will be more overlap in the corresponding area, and when the movement is fast, there will be less overlap in the corresponding area. Areas with more overlap may be too thick, affecting the heat dissipation effect during installation or use in the vehicle; areas with less overlap will not provide sufficient protection for the wires and will be easily worn by friction or environmental factors.

[0003] With the development of automation, some wire harnesses have achieved automatic winding. However, the angle switching of the tape during the winding process and the separation of the tape after winding are still technical challenges that need to be addressed. Summary of the Invention

Detailed Implementation

[0045] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0046] Please refer to Figures 1-3. This embodiment provides an automatic wire tape winding and finishing device, including a mounting platform 100. The mounting platform 100 is equipped with a tape winding mechanism and a tape cutting mechanism. The tape winding mechanism includes a turntable 200 slidably mounted on the mounting platform 100, used to carry the tape roll and adjust the output angle of the tape roll. The turntable 200 is provided with a base plate 210 for mounting the tape roll, and a matching rotating shaft 220 is provided on the base plate 210 corresponding to the tape roll. The tape cutting mechanism includes components fixedly mounted on the mounting platform 100. The device includes a base 300 and a cutter 310 slidably mounted on the base 300. The cutter 310 is connected to the base 300 via a slide block 320, and the sliding direction is parallel to the sliding direction of the turntable 200. The slide block 320 is provided with a slide table 321 for mounting the cutter 310 and can slide relative to it. The slide table 321 is also provided with a locking block 330 on one side of the cutter 310, and the sliding direction is perpendicular to the mounting table 100. The locking block 330 is located above the wire harness and includes a V-shaped locking groove 331 for wrapping the cut end of the tape around the wire harness.

[0047] In this embodiment, the base of the turntable 200 is slidably mounted on the mounting platform 100, and a base plate 210 for mounting the tape roll is fixedly mounted on the top. Its sliding direction is parallel to the length direction of the wire harness. When the end of the tape is bonded to the wire harness, the tape roll is driven to slide synchronously during the rotation of the wire harness, so that the tape can be evenly wound on the wire harness.

[0048] In this embodiment, the initial position of the turntable 200 is located at the end of the wire harness where the terminal is located, and the output angle of the tape is perpendicular to the wire harness. After the end of the tape is bonded to the wire harness and wrapped a specified number of times, the turntable 200 first rotates 45° to form a 45° angle between the tape and the wire harness, and then slides at a constant speed towards the end of the wire harness away from the terminal. At the same time, the wire harness also rotates synchronously to make the tape evenly wrapped around the wire harness.

[0049] In this embodiment, the tape cutting mechanism is installed at the end of the wire harness away from the terminal. When the tape is wound to the designated position, the slide 320 first drives the cutter 310 to move above the tape, and then the slide 321 presses down to cut the tape. At the same time as the tape is cut, the wire harness will also enter the slot 331 on the card block 330. Then, by rotating the wire harness, the end of the tape can be completely wrapped and glued to the wire harness.

[0050] In a preferred embodiment, the substrate 210 is further provided with an auxiliary plate 230 that can slide relative to it, and the sliding direction is parallel to the mounting platform 100; the auxiliary plate 230 is provided with a support seat 231 and an air jet pipe 232 respectively corresponding to the tape; the support seat 231 is fixedly installed on the auxiliary plate 230 for supporting the end of the tape; the air jet pipe 232 is fixedly installed on the auxiliary plate 230, and the output end extends to the side of the auxiliary plate near the wire harness for maintaining the end of the tape in a horizontal suspended state.

[0051] In this embodiment, the auxiliary plate 230 is located on the side of the substrate 210 near the wire harness and can slide relative to the substrate 210; the auxiliary plate 230 is L-shaped and the bent part is located at the bottom, and is used to install the support base 231 and the jet pipe 232.

[0052] In this embodiment, the support base 231 is fixedly installed above the bend to support the end of the tape; the jet pipe 232 is fixedly installed below the bend, and the output end extends to the side of the auxiliary plate 230 near the wire harness, so that the end of the tape can be directly sprayed and supported, keeping the end of the tape suspended in a horizontal state; with the sliding of the auxiliary plate 230, the end of the tape can be transported above the wire harness.

[0053] In a preferred embodiment, the auxiliary plate 230 is further provided with a pressing cylinder 233; the pressing cylinder 233 is located directly above the support base 231, and the output end is provided with a corresponding clamp corresponding to the support base 231, for pressing the tape onto the support base 231 and moving synchronously with the auxiliary plate 230.

[0054] In this embodiment, the pressing cylinder 233 is located directly above the support base 231, and its extension and retraction direction is perpendicular to the support base 231. A clamp is provided corresponding to the support base 231 to press the tape onto the support base 231, so that the tape can move synchronously with the auxiliary plate 230 during the movement of the auxiliary plate 230.

[0055] In this embodiment, the top of the support base 231 is arc-shaped, which can both cooperate with the clamp to clamp the tape and reduce the contact area with the tape to prevent the tape from sticking to the support base 231.

[0056] In a preferred embodiment, the auxiliary plate 230 is further provided with a pressing cylinder 240; the pressing cylinder 240 is fixedly installed on the auxiliary plate 230, and a pressing head 241 is installed at the output end; the pressing head 241 is inverted L-shaped, including a mounting part connected to the pressing cylinder 240 and a bending part perpendicular to the mounting part; the bending part is located above the jet pipe 232 and is used to press the end of the tape into the two guides of the wire harness.

[0057] In this embodiment, the pressing cylinder 240 is located on the side of the clamping cylinder 233 near the wire harness, and its extension and retraction direction is parallel to that of the clamping cylinder 233. At the same time, a pressing head 241 is also installed on the pressing cylinder 240. The pressing head 241 is L-shaped, with the bending direction facing downward, and extends above the output end of the jet pipe 232. During operation, the wire harness is located between the jet pipe 232 and the tape. By pressing down, the pressing head 241 can press the tape into the space between the two wires in the wire harness, and the tape cannot detach from the wire harness as the pressing head 241 resets.

[0058] In a preferred embodiment, the auxiliary plate 230 is connected to the base plate 210 via an extension plate; the extension plate is slidably connected to both the auxiliary plate 230 and the base plate 210, and the sliding directions are the same.

[0059] In this embodiment, the auxiliary plate 230 is connected to the base plate 210 through the extension plate, and they can slide against each other, thereby realizing the two-stage extension of the auxiliary plate 230, which not only has a larger stroke, but also makes it easier to control according to the usage environment.

[0060] In a preferred embodiment, an unwinding mechanism is further provided on the substrate 210 between the rotating shaft 220 and the auxiliary plate 230; the unwinding mechanism includes a telescopic cylinder 260 fixedly installed on the substrate 210 and guide rollers 261 located on both sides of the telescopic cylinder 260; the telescopic direction of the telescopic cylinder 260 is perpendicular to the mounting platform 100, and the output end is provided with a support roller that can rotate relative to it.

[0061] In this embodiment, the end of the tape roll passes sequentially through the first guide roller 261, the support roller, and the second guide roller 261, which not only changes the output direction of the tape but also limits the path of the tape. After the tape finishes winding the previous wire harness and each mechanism is reset, the end of the tape needs to be clamped by the clamping cylinder 233 first, and then the telescopic cylinder 260 is driven to extend, separating a portion of the tape from the tape roll in advance. Then the air source of the telescopic cylinder 580 is cut off, so that the telescopic cylinder 580 can automatically retract under force during the tape winding process, without causing resistance to the output of the tape. At the same time, it also avoids the excessive tension on the wire harness caused by the tape unwinding during continuous winding, which would affect the winding effect.

[0062] In a preferred embodiment, the mounting platform 100 is further provided with a wire harness clamping mechanism for mounting and driving the wire harness to rotate; the wire harness clamping mechanism includes a terminal clamping assembly and a wire clamping assembly arranged along the sliding direction of the turntable 200; the terminal clamping assembly is used to connect to the terminal end of the wire harness and is relatively far away from the tape cutting mechanism; the wire clamping assembly is used to connect to the wire end of the wire harness and is mounted on the base 300.

[0063] In this embodiment, the wire clamping assembly includes a gripper cylinder that is slidably mounted on the base 300 via a first slide table; the gripper cylinder and the first slide table are rotatably connected via a first rotating shaft; the base 300 is also provided with a first drive shaft; one end of the first drive shaft is retractably connected to the first rotating shaft via a spline groove, and the other end is connected to the drive mechanism.

[0064] During operation, first install the terminal at one end of the wire harness on the terminal clamping assembly, then install the wire at the other end on the clamping cylinder. Finally, start the wire clamping assembly. By sliding between the first slide and the base 300, the wire harness can be tightened, thus effectively ensuring the effect of the tape. Since the first drive shaft and the first rotating shaft are connected by a spline groove, they will always be connected even if there is displacement between the first rotating shaft and the first drive shaft.
