Description

Technical Field

[0001] The present application relates to the technical field of installing waterproof plugs on automobile wiring harnesses, and in particular to an automatic threading machine for waterproof plugs on automobile wiring harnesses. Background Art

[0002] A waterproof plug is a type of silicone used in automotive wiring harness connectors that prevents water from entering the connector. The plug is inserted into the wiring harness and into the connector to provide waterproofing. During installation, a semi-automatic or fully automatic plug-threading machine is typically used to attach the plug to the stripped portion of the wiring harness. During operation, the semi-automatic plug-threading machine attaches the plug to a thimble, which is held in a vertical position. The thimble then rotates to a horizontal position. The operator then places a single wire harness on the machine's threading table. The harness and thimble are now coaxial, and the table secures the harness. The thimble then moves forward, forcing the plug to attach to the harness.

[0003] However, when loading the wire harness, the operator needs to take out a single wire harness from the bundled wire harness, and then place the wire harness on the threading table. The semi-automatic waterproof plug threading machine then threads the waterproof plug on the wire harness, and takes out a single wire harness from the bundled wire harness and then performs the needle threading operation, resulting in a relatively average threading efficiency of the waterproof plug.

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The embodiment of the present application discloses an automatic threading machine for automotive wiring harness waterproof plugs. Figure 1 and Figure 2 The automatic threading machine for automobile wiring harness waterproof plugs includes a threading machine body 1, and a separator 2 is provided on the threading machine body 1. The separator 2 includes a separator strip 21 and a plurality of separator cylinders 22 provided on the separator strip 21. The separator cylinders 22 are evenly distributed on the separator strip 21. The separator cylinders 22 are used to sleeve the wiring harness. The inner diameter of the separator cylinder 22 is greater than 1 times the diameter of the wiring harness and less than 2 times the diameter of the wiring harness. The separator strip 21 is used to reel the separator cylinder 22 into the separator strip 21 when its own end edge is used as the reeling axis; the bundled wiring harness is used to be inserted into the reeled separator 2, and the wiring harness not inserted into the separator cylinder 22 is moved out, and then the separator strip 21 is unwound in a horizontal state, and then the wiring harness is pushed into the threading platform on the threading machine body 1.

[0025] When installing the wiring harness, first roll up the dividing cylinder 22 through the dividing tape 21. At this time, the dividing tape 21 is cylindrical. Then, the bundled wiring harness is plugged toward the dividing tape 21. Part of the wiring harness is plugged into the dividing cylinder 22. Then, the wiring harness that is not plugged into the dividing cylinder 22 is separated, and the dividing tape 21 is unwound to make the dividing tape 21 flat. Because the inner diameter of the dividing cylinder 22 is greater than 1 times the diameter of the wiring harness and less than 2 times the diameter of the wiring harness, there is only one wiring harness in the dividing cylinder 22, which makes it easier for the operator to quickly separate the wiring harness and send the separated wiring harness into the threading platform, thereby improving the threading efficiency of the waterproof plug.

[0026] Reference Figure 3 and Figure 4 In the embodiment of the present application, in order to facilitate the delivery of the wire harness in the separation cylinder 22 into the threading platform, the threading machine body 1 is provided with a workbench 3 in front of the threading platform, and a reel 4 is rotatably provided on the workbench 3, and the rotation axis of the reel 4 is parallel to the surface of the workbench 3. One end edge of the dividing tape 21 is fixed on the reel 4, and a receiving plate 5 is provided on the workbench 3. The receiving plate 5 is parallel to the workbench 3. The dividing tape 21 unwound from the reel 4 is laid flat on the receiving plate 5, and the dividing cylinder 22 laid flat on the receiving plate 5 is flush with the thimble; the reel 4 rotates to reel the dividing tape 21, and then the wire harness is inserted into the separation cylinder 22, and then the wire harness not inserted into the separation cylinder 22 is separated, and then the end of the dividing tape 21 is pulled, and the dividing tape 21 is released from the reel 4 and laid flat on the receiving plate 5, which makes it convenient for the operator to push the wire harness into the threading platform.

[0027] Reference Figure 3 and Figure 4In the embodiment of the present application, the docking plate 5 is initially laid flat on the workbench 3. The docking plate 5 is slidably mounted on the workbench 3, sliding perpendicularly to the workbench 3 surface. The workbench 3 is provided with a first driving member for driving the docking plate 5 to slide and adjust its height. The first driving member comprises a cylinder 6 mounted on the workbench 3. The length of the piston rod of the cylinder 6 is perpendicular to the workbench 3, and the docking plate 5 is fixedly mounted on the piston rod of the cylinder 6. By adjusting the height of the docking plate 5 via the cylinder 6, the height of the wiring harness can be adjusted, thereby facilitating alignment of the wiring harness with the ejector pin and facilitating the insertion of the waterproof plug into the wiring harness.

[0028] Reference Figure 3 and Figure 4 After the dividing tape 21 is laid flat on the receiving plate 5, as the wiring harness completes the installation of the waterproof plug, it is necessary to adjust the dividing tape 21 facing the ejector pin. At this time, if the dividing tape 21 is wound up by rotating the reel-up shaft 4 and the dividing tape 21 is driven to move, the running speed of the dividing tape 21 is difficult to control. Therefore, in the embodiment of the present application, the reel-up shaft 4 is slidingly arranged on the workbench 3, and the reel-up shaft 4 slides in the horizontal direction. The reel-up shaft 4 slides and drives the dividing tape 21 to move, so that the wiring harness in the adjacent separating cylinder 22 is facing the ejector pin. The reel-up shaft 4 is provided with a second driving member for driving the reel-up shaft 4 to slide; the reel-up shaft 4 is driven to move evenly on the workbench 3 by the second driving member, and the reel belt moves evenly and drives the dividing tape 21 to move evenly, so that the separating cylinder 22 can drive the wiring harness to face the ejector pin.

At this time, the dividing tape 21 is wound on the winding shaft 4, and then the bundled wire harness is moved to the top of the dividing cylinder 22, and then the wire harness is inserted into the dividing cylinder 22. Compared with the dividing cylinder 22 in a horizontal state, the dividing cylinder 22 in a vertical state facilitates the wiring harness to be inserted into the dividing cylinder 22.

[0037] The implementation principle of an automatic threading machine for automotive wiring harness waterproof plugs in the embodiment of the present application is as follows:
