Description

Technical Field

[0001] This application relates to the field of mechanical automation technology, specifically to a tape positioning and insertion device. 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, how to automatically attach tape to the wire harness before winding remains a technical challenge that urgently needs to be solved. Summary of the Invention

Detailed Implementation

[0041] 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.

[0042] Please refer to Figure 1-2This embodiment provides a tape positioning and insertion device, including a base plate 100, which is vertically mounted on a mounting platform 200. One side of the base plate 100 is provided with a rotating shaft 110 for mounting a tape roll and a pressing cylinder 120 for inserting the tape into a wire harness. The mounting platform 200 is provided with a turntable 210 for mounting the base plate 100 and for adjusting the output angle of the tape. A pressing head 121 is mounted on the pressing cylinder 120, and its extension / retraction direction is perpendicular to the mounting platform 200. The pressing head 121 is inverted L-shaped, located below the pressing cylinder 120, and its bending direction is downward. A straightening mechanism is located below the pressing cylinder 120 and includes an air jet pipe 300. The output end of the air jet pipe 300 is located directly below the bent portion of the pressing head 121, and its output direction is vertical, for maintaining the end of the tape in a horizontal state.

[0043] In this embodiment, the mounting platform 200 is provided with a substrate 100 and a wire harness clamping mechanism; the wire harness clamping mechanism is used to clamp and drive the two ends of the wire harness to rotate, while the substrate 100 is equipped with a tape roll via a rotating shaft 110; after one end of the tape is attached to the wire harness, the tape can be wound around the wire harness by rotating the wire harness.

[0044] In this embodiment, the substrate 100 is slidably mounted on the mounting platform 200 via the turntable 210, so that the substrate 100 can both rotate and slide relative to the wire harness; wherein rotation can effectively adjust the output angle of the tape, while sliding can make the tape evenly wound along the length direction of the wire harness.

[0045] In this embodiment, a pressing cylinder 120 and a straightening mechanism are respectively provided on the upper and lower sides of the tape end; the straightening mechanism includes an air jet pipe 300 that can spray air; the air jet pipe can effectively counteract the weight of the tape by spraying air, so that the end of the tape is suspended and horizontal; while the pressing cylinder 120 is equipped with a pressing head 121. By controlling the pressing head 121 to press down, the end of the tape can be effectively pressed into the two wires of the wire harness located below.

[0046] In a preferred embodiment, the substrate 100 is provided with an extension plate 130 for mounting the pressing cylinder 120; the extension plate 130 is slidably mounted on the substrate 100 and the sliding direction is parallel to the mounting platform 200, for driving the pressing cylinder 120 to slide above the wire harness.

[0047] In this embodiment, the pressing cylinder 120 and the straightening mechanism are respectively connected to the base plate 100 through the extension plate 130, and the extension plate 130 and the base plate 100 can slide relative to each other. When the end of the tape needs to be bonded to the wire harness, the extension plate 130 slides with the base plate 100 to transport the pressing cylinder 120, the straightening mechanism and the end of the tape to the wire harness. Conversely, after the end of the tape is bonded to the wire harness, the pressing cylinder 120 and the straightening mechanism can be driven away from the wire harness, which facilitates the loading and unloading of the wire harness.

[0048] In a preferred embodiment, an auxiliary plate 140 is further provided between the pressing cylinder 120 and the extension plate 130; the auxiliary plate 140 is slidably mounted on the extension plate 130, located on the same side of the extension plate 130 as the base plate 100, and the sliding direction is parallel to the sliding direction between the extension plate 130 and the base plate 100, for driving the pressing cylinder 120 to extend in two stages; the pressing cylinder 120 is fixedly mounted on the side of the auxiliary plate 140 away from the extension plate 130.

[0049] In this embodiment, the extension plate 130 is also provided with an auxiliary plate 140 that can slide relative to it, and the sliding direction of the auxiliary plate 140 is the same as the sliding direction of the extension plate 130, so that the pressing cylinder 120 and the straightening mechanism installed on the auxiliary plate 140 can be extended in two stages, making it more widely applicable.

[0050] In a preferred embodiment, the auxiliary plate 140 is L-shaped and includes a first mounting portion located between the extension plate 130 and the pressure cylinder 120 and a second mounting portion located below the pressure cylinder 120 and perpendicular to the first mounting portion; the jet pipe 300 is fixedly mounted below the second mounting portion, and its output end extends to the outside of the second mounting portion.

[0051] In a preferred embodiment, the second mounting portion is further provided with a clamping assembly for clamping the tape and moving synchronously with the auxiliary plate 140; the clamping assembly includes a base 150 fixedly mounted on the second mounting portion and a pressing cylinder 160 fixedly mounted on the first mounting portion; the extending direction of the pressing cylinder 160 is perpendicular to the second mounting portion, and the output end is provided with a corresponding pressing block 161 corresponding to the base 150; the top surface of the mounting base 150 is arc-shaped to reduce the contact area with the tape, thereby facilitating separation.

[0052] In this embodiment, the clamping assembly includes a base 150 fixedly mounted on the second mounting part and a pressing cylinder 160 fixedly mounted on the first mounting part. When the end of the tape needs to be bonded to the wire harness, the tape needs to be pressed and fixed on the base 150 by the pressing cylinder 160 first, and then the extension plate 130 and the auxiliary plate 140 are driven to slide.

[0053] In a preferred embodiment, the substrate 100 is further provided with a tape unwinding mechanism; the unwinding mechanism includes a telescopic cylinder 170 fixedly installed on the substrate 100 and guide wheels 180 located on both sides of the telescopic cylinder 170; the telescopic direction of the telescopic cylinder 170 is perpendicular to the mounting platform 200, and the output end is provided with a support roller corresponding to the tape.

[0054] In this embodiment, the end of the tape roll passes through the first guide roller 180, the support roller, and the second guide roller 180 in sequence, 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 assembly first. Then, the telescopic cylinder 170 is driven to extend, separating a portion of the tape from the tape roll in advance. Then, the air source of the telescopic cylinder 170 is cut off to avoid excessive tension on the wire harness due to the unwinding force of the tape during subsequent winding, which would affect the winding effect.

[0055] In a preferred embodiment, the rotating shaft 110 is a stepped shaft, with one end of the major diameter fixedly mounted on the base plate 100, and one end of the minor diameter having an external thread; the tape roll is sleeved on the minor diameter and can rotate relative to the minor diameter; a locking nut 111 is also sleeved on the minor diameter to restrict the tape roll from detaching; the locking nut 111 is located on the side of the tape roll away from the major diameter and is threadedly connected to the minor diameter.

The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this invention, and can also combine the above technical features in an appropriate manner.
