[0002] The waterproof plug is a kind of silicone in the wiring harness connector that can prevent water from entering the automotive wiring harness connector. The waterproof plug is worn in the wiring harness and inserted in the connector to play a waterproof role.

[0003] For example, an existing patent discloses a waterproof plug device that is easy to disassemble and assemble (application number CN202322512091.4). The device includes: a frame, a swinging needle assembly, and a stripping mechanism; the stripping mechanism includes a first stripping drive assembly, a second stripping drive assembly, a clamping drive assembly, two stripping jig brackets, and two expansion tube brackets. The two stripping jig brackets are both detachably provided with stripping jigs, and the two expansion tube brackets are both detachably provided with expansion tubes. In this device, the detachable arrangement of the expansion tubes and stripping jigs makes it easier to maintain these structures when they are damaged. It is also possible to replace accessories of different models and sizes as needed to achieve the installation of wiring harnesses and waterproof plugs that are suitable for various sizes. However, during the production and processing of this waterproof plug device, only one waterproof plug can be installed on one wiring harness at a time, and the installation efficiency of this operation is still relatively low. Utility Model Content

[0004] In order to solve the above problems, the technical purpose of the present invention is to provide a waterproof plug multi-threading device, which can thread multiple waterproof plugs into and sleeve them on the wiring harness at one time, thereby effectively improving processing efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows.

[0006] A waterproof plug multi-threading device, comprising a frame, a feeding mechanism for providing waterproof plugs, and a threading mechanism for sleeve-mounting the waterproof plugs on a wiring harness; the threading mechanism and the feeding mechanism are both arranged on the frame, and the threading mechanism comprises:

[0007] A connecting component, wherein the connecting component is provided with a plurality of waterproof plug receiving positions for receiving the waterproof plug on the feeding mechanism;

[0008] A threading assembly is provided with a plurality of threading positions for stripping the waterproof plug from the waterproof plug receiving position and sleeved onto the wiring harness, the plurality of threading positions respectively corresponding to the plurality of waterproof plug receiving positions;

[0009] A connecting drive component is used to control the connecting component to connect with the feeding mechanism and the threading component respectively. The connecting drive component is driven and connected to the connecting component to control the multiple waterproof plug receiving positions to extend into the multiple threading positions respectively.

[0010] In this waterproof plug multi-threading device, multiple waterproof plugs are respectively received by the multiple waterproof plug receiving positions of the connecting component, and then the connecting driving component is used to control the movement of the connecting component to connect with the threading component, and the multiple waterproof plugs on the multiple waterproof plug receiving positions are controlled to extend into the multiple threading positions respectively, so that the multiple waterproof plugs can be simultaneously inserted into the wiring harness connected at the multiple threading positions, which can effectively improve the processing efficiency.

[0011] Furthermore, the coupling assembly includes a plurality of waterproof plug expansion tubes, the waterproof plug receiving positions being provided on the waterproof plug expansion tubes, and each of the waterproof plug expansion tubes is provided with a guide hole, with the waterproof plug receiving positions surrounding the outside of the guide hole. A coupling drive assembly controls the movement of the coupling assembly so that the plurality of waterproof plug expansion tubes extend into the plurality of threading positions, allowing the wiring harness to extend into the guide hole. When the coupling drive assembly controls the movement of the coupling assembly so that the plurality of waterproof plug expansion tubes exit the plurality of threading positions, the threading assembly peels off the waterproof plugs from the waterproof plug receiving positions on the outside of the waterproof plug expansion tubes and places them onto the corresponding wiring harness.

[0012] Furthermore, the threading assembly includes a threading body, an upper threading clamp, a lower threading clamp, an upper clamping cylinder, and a lower clamping cylinder; the upper threading clamp and the lower threading clamp are both movably arranged on the threading body, and the upper clamping cylinder and the lower clamping cylinder are both fixedly arranged on the threading body, and the upper clamping cylinder and the lower clamping cylinder are respectively connected to the upper threading clamp and the lower threading clamp to drive the upper threading clamp and the lower threading clamp to close or separate; a plurality of upper clamping holes are provided on the lower side of the upper threading clamp, and a plurality of lower clamping holes are provided on the upper side of the lower threading clamp, and the threading position adapted to the waterproof plug expansion tube is formed between the upper clamping holes and the corresponding lower clamping holes. When the connecting drive assembly controls the movement of the connecting assembly so that multiple waterproof plug expansion tubes are respectively extended to the corresponding positions of multiple threading positions, the upper clamping cylinder and the lower clamping cylinder respectively control the movement of the upper threading clamp and the lower threading clamp so that the upper threading clamp and the lower threading clamp are closed. At this time, the waterproof plug expansion tube and the corresponding lower clamping hole and upper clamping hole can be relatively movable; then the wiring harness is extended from the threading position into the corresponding guide hole, and the connecting drive assembly continues to control the movement of the connecting assembly so that multiple waterproof plug expansion tubes are respectively withdrawn from the corresponding threading positions. At this time, under the obstruction of the upper threading clamp and the lower threading clamp, the waterproof plug on the waterproof plug receiving position outside the waterproof plug expansion tube is stripped off and put on the corresponding wiring harness.

The tube expansion rotating seat is provided with a rotating wheel for controlling the tube expansion rotating seat, and the support member is provided with a rotating slot. The rotating wheel is movably mounted in the rotating slot and abuts against the side of the rotating slot. When the coupling cylinder drives the tube expansion mounting seat to move toward the threading position, the rotating wheel abuts and rolls in the rotating slot, thereby driving the tube expansion rotating seat to rotate on the tube expansion mounting seat, so that the waterproof plug expansion tube is adjusted from a posture aligned with the feeding mechanism to a posture aligned with the threading position.

[0014] Furthermore, the waterproof plug multi-threading device also includes a threading cylinder for controlling the movement of the threading mechanism to thread the wire harness into the threading position. The threading cylinder is drivably connected to the threading mechanism.

[0017] Furthermore, the feeding mechanism includes:

[0018] A loading component for loading waterproof plugs;

[0019] A needle for inserting the waterproof plug, the needle being located above the loading assembly and the waterproof plug receiving position;

[0020] A first needle driving assembly for controlling the needle to be threaded and corresponding to the loading assembly and the waterproof plug receiving position respectively;

[0021] A second needle drive assembly is used to control the needle's elevation.
