[0039] Plug-in board 1 is equipped with parallelly arranged feed hole 11 and plug-in hole 12, the feed hole 11 is communicated with feed pipe;

[0040] Material moving plate 2 is located in the outside of plug-in board 1, is equipped with material moving hole 21, side is equipped with control structure 5, for controlling the material moving hole 21 of material moving plate 2 and the feed hole 11 or plug-in hole 12 of plug-in board 1 alignment;

[0041] Guide structure 3 is arranged in the outside of material moving plate 2, is equipped with guide hole, the guide hole is aligned with the center hole of waterproof plug in material moving hole 21;

[0042] Wire clamping structure, including fixed clamp, for clamping wire harness, and waterproof plug is inserted into the center hole position of material moving hole 21.

[0043] Through the movement of material moving plate 2, make material moving hole 21 and feed hole 11 alignment, waterproof plug in the position of feed pipe is entered material moving hole 21 through feed hole 11, then in the process of moving material moving hole 21 waterproof plug is moved to the alignment position of plug-in hole 12, then again with wire harness plug-in, in the process, the outermost position waterproof plug is taken out separately by the movement of material moving plate 2, and is completed plug-in in material moving hole 21 position, can guarantee that one waterproof plug is taken out each time, and plug-in process is completed separately, to improve the plug-in quality of wire harness and waterproof plug.

[0044] At this time, the inner diameter of the feeding pipe is matched with the waterproof plug, the waterproof plug can move along the pipe direction in the feeding pipe, and the waterproof plug moves in the feeding pipe, first enters the feeding hole 11, and when the feeding hole 21 of the material moving plate 2 is aligned with the feeding hole 11, the waterproof plug in the feeding pipe moves as a whole, so that the waterproof plug at the position of the feeding hole 11 enters the feeding hole 21 of the material moving plate 2, and then the material moving plate 2 synchronously moves the waterproof plug at the position of the feeding hole 21 to the position of the plug-in hole 12, so that the taking-out process of a single waterproof plug is completed, and the subsequent plug-in of the wire harness and the waterproof plug is facilitated.

[0045] In the embodiment, the wire clamping structure is used to clamp and move the wire harness, and the prior art is adopted, and thus detailed description is not made herein. Meanwhile, the feeding process of the waterproof plug into the feeding pipe and the control are also the prior art, and thus detailed description is not made herein.

[0046] In the process of inserting the wire harness into the center hole of the waterproof plug, it is necessary to ensure that the end of the wire harness is aligned with the center hole of the waterproof plug, and thus in the embodiment, the guide structure 3 includes a guide cylinder 31, the guide cylinder 31 is provided with two piston rods, the piston rods are fixed with guide blocks 32, the two guide blocks 32 are provided with corresponding guide grooves 33, the guide cylinder 31 controls the two guide blocks 32 to move inward or outward at the same time, and the two guide grooves 33 are closed or opened. The guide cylinder 31 is arranged at the upper side of the material moving plate 2, at this time, the guide blocks 32 are located outside the material moving plate 2, one of the guide blocks 32 is arranged at a smaller distance from the material moving plate 2, so that the guide blocks 32 and the material moving plate 2 can move relatively, under the action of the guide cylinder 31, the two guide blocks 32 move transversely, so as to form the guide grooves 33, or the two guide blocks 32 move outward and are separated, so as to facilitate the moving-out of the wire harness after being plugged into the waterproof plug.

[0047] In the process of moving the waterproof plug into the material moving hole 21 and the waterproof plug being in the material moving hole of the material moving plate 2 and the material moving plate 2 moving laterally, it is necessary to ensure that the waterproof plug cannot fall out of the material moving hole 21, so in this embodiment, when the material moving hole 21 moves to be aligned with the feeding hole 11, the guide block 32 of the guide structure 3 is located at the outer side of the material moving hole 21, which is used to seal the outer side of the material moving hole 21. That is, when the guide block 32 moves to the outermost position and the material moving plate 2 moves to the position where the material moving hole 21 is aligned with the feeding hole 11, the guide block 32 is located at the outer side of the material moving hole 21 at this time. When the waterproof plug enters the material moving hole 21, the waterproof plug cannot fall out of the opening of the material moving hole 21 due to the blocking of the guide block 32 at the outer side of the material moving hole 21. At the same time, the depth of the material moving hole 21 is matched with the length of a waterproof plug, that is, only one waterproof plug can be accommodated in the material moving hole 21. During the movement of the material moving plate 2 (the material moving hole 21 of the material moving plate 2 moves towards the plug-in hole 12), the guide cylinder 31 controls the synchronous movement of the guide block 32 (moves towards the direction of the two guide blocks 32 being combined), so that at least part of the guide block 32 is always located at the outer side of the material moving hole 21, thereby blocking the outer side of the material moving hole 21 by the guide block 32, avoiding the waterproof plug in the material moving hole 21 from falling out during the movement of the material moving plate 2, and ensuring the stability of the waterproof plug during the movement.

[0048] The material moving plate 2 needs to move laterally during use, so in this embodiment, the control structure 5 includes a guide rail slider structure 51 arranged between the material moving plate 2 and the plug-in plate 1, the guide direction of the guide rail slider structure 51 is parallel to the direction of the axis connecting line between the feeding hole 11 and the plug-in hole 12, and the plug-in plate 1 side is fixed with a control cylinder 52, and the piston rod of the control cylinder 52 is fixed with the material moving plate 2. Under the action of the cylinder, the material moving plate 2 moves along the guide direction, thereby controlling the lateral movement of the material moving plate 2.

[0049] After the material moving hole 21 of the material moving plate 2 moves to the position of the plug-in hole 12, the plug-in process with the wire harness needs to be completed. In this embodiment, in order to better plug in the wire harness, at this time, the plug-in hole 12 is a through hole, the plug-in hole 12 is conical as a whole, and the inner diameter of the side close to the material moving plate 2 is larger than the inner diameter of the side away from the material moving plate 2. In this way, it can be avoided that the waterproof plug enters the plug-in hole 12 during the plug-in process with the wire harness, and at the same time, the wire harness can enter the plug-in hole 12 after passing through the waterproof plug, thereby ensuring the plug-in effect of the waterproof plug and the wire harness. Further, a nylon sleeve 22 is arranged at the inner side of the material moving hole 21, and a stepped hole is arranged in the middle of the nylon sleeve 22. The nylon sleeve 22 can avoid damaging the waterproof plug, and after the stepped hole is arranged, the waterproof plug can be repositioned to ensure that the waterproof plug will not move to the inner position of the plug-in hole 12.

[0050] Meanwhile, in order to adapt to different types of waterproof plugs, the feeding device further comprises a fixing plate 6 provided with a plurality of arranged positioning grooves 61, the plug-in plate 1 is fixed in the positioning groove 61, the fixing plate 6 is provided with a fixing hole 62 corresponding to the feeding hole 11, and the feeding pipe is fixed with the fixing plate 6 at the position of the fixing hole 62. A plurality of feeding pipes are arranged, and a plurality of corresponding fixing plates 6, plug-in plates 1 and material moving plates 2 are arranged, so that a plurality of same or different types of waterproof plugs can be corresponded, thereby reducing the debugging and replacement time of the equipment.

[0051] After a plurality of material moving plates 2 are arranged, corresponding guide blocks 32 also need to be arranged, therefore, in the embodiment, the guide structure 3 further comprises two parallel arranged moving rods 34 distributed along the direction of the arranged positioning grooves 61, the moving rod 34 is fixed with the piston rod of the guide cylinder 31 at the end, the guide block 32 is fixed on the side of the moving rod 34, and the guide block 32 is arranged corresponding to the material moving plate 2 at the position of the positioning groove 61. At this time, only one guide cylinder 31 can control the transverse movement of a plurality of guide blocks 32, thereby simplifying the overall structure, and a plurality of guide blocks 32 can be controlled.

[0052] A waterproof plug feeding method for wire harness terminal crimping, characterized in that the material moving plate 2 is controlled to move, so that the material moving hole 21 of the material moving plate 2 is aligned with the feeding hole 11;

[0053] The waterproof plugs arranged in the feeding pipe are controlled to move to the position of the material moving hole 21 of the material moving plate 2 through the feeding hole 11;

[0054] The material moving plate 2 is controlled to move, so that the material moving hole 21 of the material moving plate 2 moves from the position aligned with the feeding hole 11 to the position aligned with the plug-in hole 12, and the guide blocks 32 of the guide structure 3 are controlled to close to form a guide groove 33, so that at least part of the guide blocks 32 covers the outside of the material moving hole 21;

[0055] The wire harness is clamped by the wire clamping structure and inserted from the position of the guide groove 33, so that the wire harness is inserted into the waterproof plug;

[0056] The guide blocks 32 of the guide structure 3 are controlled to separate, and the wire harness with the inserted waterproof plug is taken out by the wire clamping structure.

[0057] When the waterproof plug enters the material moving hole 21 and moves synchronously in the material moving hole 21, the guide blocks 32 are arranged outside the material moving hole 21, so that at least part of the position of the material moving hole 21 is blocked, thereby avoiding the waterproof plug from falling out of the material moving hole 21, and further ensuring that the overall production process can be carried out normally.

[0058] At this time, after the waterproof plugs arranged in the feeding pipe are controlled to move through the feeding hole 11, it is necessary to detect whether the waterproof plugs enter the material moving hole 21.

[0059] After the wire harness with the waterproof plug is taken out, it is necessary to detect whether there is a waterproof plug left in the moving hole 21 of the moving plate 2, and specifically, the moving plate is provided with a transverse through hole which is in communication with the moving hole 21, and sensors (such as optical fiber sensors) are arranged on both sides of the through hole of the moving plate, so that whether there is a waterproof plug in the moving hole 21 can be detected through the sensors, thereby avoiding that the waterproof plug does not normally enter the moving hole 21 due to equipment failure, or that the waterproof plug with the wire harness is not taken out due to failure, thereby affecting the normal production rhythm.

[0060] At this time, after the wire harness is inserted into the waterproof plug, it is necessary to detect whether the wire harness inserted into the waterproof plug meets the preset requirements, including detecting whether the length of the wire harness in the insertion hole 12 after insertion meets the preset length requirement, and at this time, a pressure sensor is arranged in the interior or bottom of the insertion hole 12, in the process of inserting the wire harness into the waterproof plug, the wire harness passes through the waterproof plug and extends into the insertion hole 12, at this time, the wire harness continues to be inserted forward, and the wire harness will contact the pressure sensor, and the wire harness stops inserting when the pressure sensor detects the pressure of the wire harness, so that the wire harness just contacts the pressure sensor, thereby the length of the wire harness inserted into the waterproof plug can be limited, thereby realizing the control of the insertion degree of the wire harness.

[0061] The technical features of the above-described embodiments can be combined in any manner, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
