[0002] In the manufacturing of automotive wiring harnesses and electronic equipment cables, terminal crimping is a core process for connecting wires and terminals. The wire feeding device, a key component of the terminal crimping equipment, precisely guides the wire harness into the crimping die. In existing technologies, the wire feeding device typically employs a fixed guide wheel assembly and guiding structure, using a wire reel (or feed reel) to carry and transport the wire.

[0003] However, existing infeed devices have significant drawbacks: when production tasks are switched to wire harnesses of different diameters or types, the entire wire spool must be disassembled and replaced, or even the entire infeed device must be replaced. The rigid adaptability of such mechanical structures makes production line changeovers take up to tens of minutes, severely restricting production efficiency, and causing accelerated equipment wear due to frequent disassembly and assembly.

[0026] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figures 1 to 3 As shown, a wire feed device for crimping wire harness terminals is characterized by comprising a wire frame 1, wherein the wire frame 1 is provided with a plurality of vertically arranged wire feed tubes 11, wherein the wire feed tubes 11 have a segmented structure.

[0030] The up-down control structure 2 is used to control the up-down movement of the wire frame 1.

[0031] There are two sets of transmission rollers 3, located on both sides of the wire frame 1. The transmission rollers 3 are located between the two end inlet pipes 11.

[0032] Multiple cable inlet tubes 11 are arranged side by side on the upper and lower sides of the cable rack. During use, multiple wire harnesses of the same or different models can be passed through the cable inlet tubes 11. The upper and lower control structure 2 controls the upper and lower movement of the cable rack 1. During the production process, the wire harnesses can be transmitted according to the preset requirements, thereby completing the automatic wire harness feeding process. The switching process of the wire harnesses is fully automated, thereby improving production efficiency.

[0033] In this embodiment, to facilitate the fixing of the inlet pipe 11, the cable frame 1 includes a vertically arranged vertical support 12. Horizontal supports 13 are fixed at both ends of the vertical support 12. The vertical support 12 has fixing holes corresponding to the inlet pipe 11. The inlet pipe 11 is positioned at the fixing holes and the vertical support 12. Two horizontal supports 13 are provided, located at both ends of the vertical support 12, thereby fixing the vertical support 12. The number of vertical supports 12 is determined according to the number of inlet pipes 11. Specifically, since the inlet pipe 11 adopts a segmented structure, each segment of the inlet pipe 11 requires at least one vertical support 12 for fixing, thus securing all the inlet pipes 11.

[0034] To ensure better cable entry during the cable feeding process, the cable tray 1 also includes a cable entry bracket 14. This bracket has a cable entry hole 141 corresponding to the cable entry tube 11. The cable entry bracket 14 is located near the side of the cable tray 1 where the cable bundles are stored. The cable entry bracket 14 is positioned between two horizontal sections, parallel to the vertical bracket 12. It has a cable entry hole 141 corresponding to the cable entry tube 11. After the cable bundle is drawn from the cable reel, it passes through the cable entry hole 141 and then enters the cable entry tube 11. This ensures that multiple cable bundles can move along the path of the cable entry hole and the cable entry tube, thus ensuring that the cable bundles are neat and orderly during the cable feeding process and improving the cable feeding efficiency.

[0035] At this point, since the wire harness inside the inlet tube needs to be moved by the transfer roller 3, the wire harness needs to contact the transfer roller 3. Therefore, the inlet tube 11 needs to be divided into a multi-segment structure, and the transfer roller 3 is positioned between the multiple segments of the inlet tube 11. Specifically, in this embodiment, the inlet tube 11 includes a first segment 111 and a second segment 112 spaced apart. The transfer roller 3 is positioned between the first segment 111 and the second segment 112, with the second segment 112 closer to the wire rack 1 storing the wire harness. Thus, the inlet tube 11 is divided into at least two segments, specifically the first segment 111 and the second segment 112, and the transfer roller 3 is positioned between the first segment 111 and the second segment 112. This exposes the wire harness between the first segment 111 and the second segment 112, and the exposed portion contacts the transfer roller 3, allowing the wire harness inside the inlet tube 11 to be moved by the transfer roller 3.

[0036] Since there are multiple vertically arranged inlet pipes 11, but only one transmission roller 3, only the wire harness in one of the inlet pipes 11 needs to be fed during production. Therefore, it is necessary to control the vertical relative movement between the inlet pipe 11 and the transmission roller 3. Specifically, in this embodiment, the vertical control structure 2 includes a vertically arranged linear module 21. The moving end of the linear module 21 is provided with a fixing clamp 22. The fixing clamp 22 includes a fixing groove adapted to the horizontal support 13. A fixing bolt is provided on the upper side of the fixing groove for fixing the horizontal support 13 in the fixing groove. Under the action of the linear module 21, the fixing clamp 22 moves vertically, thereby causing the wire frame 1 with the fixing clamp 22 to move vertically, controlling the alignment of the inlet pipe 11 at different positions with the transmission roller 3, thereby completing the movement of the wire harness in a specific inlet pipe 11.

[0037] The transmission roller 3 acts on the wire harness, thereby causing the wire harness to move. Specifically, in this embodiment, the transmission roller 3 includes a moving plate 31. A transmission wheel 32 and a drive wheel 33 are rotatably mounted on the upper side of the moving plate 31. A transmission belt is provided on the outer side of the transmission wheel 32 and the drive wheel 33. The drive wheel 33 is equipped with a drive motor for driving its rotation. The transmission belt is located between the first inlet pipe 111 and the second inlet pipe 112. A longitudinal motor is provided on the outer side of the moving plate 31 for controlling the moving plate 31 to move closer to or away from the inlet pipe 11. Under the action of the drive motor, the drive wheel 33 rotates, and the transmission belt and transmission wheel 32 rotate. Simultaneously, the longitudinal motor controls the movement of the moving plate 31, thereby causing the transmission belt to contact the wire harness, thus allowing the wire harness to move within the inlet pipe.

[0038] To ensure the stability of the wire harness during its movement within the inlet tube 11, in this embodiment, the inlet tube 11 further includes a third inlet tube 113. The wire harness passes sequentially from the third inlet tube 113 through the second inlet tube 112 and the first inlet tube 111. A front-end inlet roller 34 is provided between the third inlet tube 113 and the second inlet tube 112. Two front-end inlet rollers are provided, located on opposite sides of the wire frame 1. A front-end drive motor is provided under the front-end inlet roller 34 to control its rotation. Under the action of the front-end inlet roller 34, two forces are generated to propel the wire harness, thereby making the wire harness more stable during movement.

[0039] Since the contact position between the front feed roller 34 and the wire harness is an arc surface, and the initial contact position between the conveyor belt and the wire harness is also an arc surface, in order to reduce the exposed length of the wire harness when it contacts the front feed roller 34 and the conveyor belt, in this embodiment, the third section feed pipe 113 near the front feed roller 34 and both ends of the second section feed pipe 112 are provided with arc surfaces or inclined surfaces. The arc surfaces or inclined surfaces face the vertical sides of the front feed roller 34 and the conveyor belt. In this way, the distance between the first section feed pipe 111, the second section feed pipe 11, and the third section feed pipe 113 can be reduced, thereby reducing the exposed length of the wire harness at these positions, thus reducing the influence of the external environment on the wire harness. At the same time, the wire harness is more stable during movement and is not easy to drift, ensuring the stability of the wire harness during the overall movement process.

[0040] Because multiple inlet pipes 11 are provided, when switching the wire harness input in different inlet pipes 11, in order to ensure the stability of the wire harness in other inlet pipes 11, the wire harness needs to be clamped and fixed to the inlet pipe 11. Therefore, in this embodiment, as... Figure 2 and Figure 3As shown, the outer side of the inlet tube 11 is provided with a clamping structure 4. The clamping structure 4 includes a clamping tube 41 arranged perpendicularly to the inlet tube 11. The vertical support 12 is provided with a corresponding through hole. The clamping tube 41 is provided with a waist-shaped hole 42 corresponding to the inlet tube 11. The inlet tube 11 passes through the clamping tube 41 at the waist-shaped hole 42. The two ends of the inlet tube 11 on the inner side of the clamping tube 41 are respectively provided with an elastic element 43 and a clamping rod 44. The side wall of the inlet tube 11 is provided with a through hole corresponding to the clamping rod 44. Under the action of the elastic element 43, the clamping rod 44 is inserted into the inner side of the inlet tube 11 from the through hole. The outer side of the clamping tube 41 is provided with a release cylinder 5. The piston rod of the release cylinder 5 is connected to a top rod 51 corresponding to the clamping tube 41. When the top rod 51 acts on the clamping tube 41, the clamping tube 41 moves along the long side of the waist-shaped hole 42, so that the clamping rod moves out from the inner side of the inlet tube 11.

[0041] At this time, the clamping structure can be set at any position of the inlet tube 11 to press the wire harness. However, in order to ensure that the wire harness does not shake after being pressed and to facilitate the clamping and movement of the wire harness to the next work station after being pressed, the clamping structure is set at the position of the first section of the inlet tube 111, that is, the end position of the wire frame. In this way, the clamping position of the clamping structure is close to the position where the wire harness is cut, thereby improving the stability of the end position of the wire harness.

[0042] Specifically, under the action of the elastic element 43, the clamping rod 44 is inserted into the inner side of the first section of the inlet tube 111 from the through hole position, thereby clamping the wire harness inside. When it is necessary to move the wire harness in this position, the piston rod of the outer release cylinder 5 is controlled to move outward, so that the outer push rod 51 of the piston rod acts on the clamping tube 41, and the clamping tube 41 moves along the direction of the waist-shaped hole 42, thereby causing the clamping rod 44 to move out of the first section of the inlet tube 111, thereby releasing the force on the wire harness inside the inlet tube 11, and the wire harness inside the inlet tube 11 can move freely.

[0043] At this point, each of the vertically arranged first-section inlet pipes 111 has a corresponding clamping structure 4 on its outer side. Only one release cylinder 5 and a push rod 51 are needed. The release cylinder 5 is fixed to the side of the moving plate 31 of the transmission roller 3, flush with the transmission belt of the transmission roller 3. In this way, the transmission belt and the push rod 51 act on the inlet pipes 11 at the same height, allowing the wire bundle inside the inlet pipe 11 to move freely. However, for other inlet pipes 11, without a clamping structure, during the switching of inlet pipes 11, the wire bundle inside the inlet pipe 11 (especially the first-section inlet pipe 111) will move due to the up-and-down movement of the inlet pipe 11, causing the end of the wire bundle inside the inlet pipe 11 to move. This prevents the clamping structures in subsequent stations from functioning properly. The method cannot accurately obtain the position of the wire harness end after movement, thus preventing the wire harness from moving. However, after setting up the clamping structure, before switching between different inlet tubes 11, the wire harness needs to be clamped at the position of the first inlet tube 111 by the clamping structure, so as to ensure that the end position of the wire harness in the first inlet tube 111 is fixed. In this way, no matter how the inlet tube 11 is moved, the positional relationship between the wire harness inside and the inlet tube 11 remains unchanged. In this way, if the wire harness in the inlet tube 11 is used again, after switching to the transmission belt position, the grippers and other structures of the subsequent station can normally grab the wire harness in the wire harness tube, thus ensuring that the wire harness in all inlet tubes 11 can be normally grabbed and moved during the process of switching between different inlet tubes 11.

[0044] A wire feed method for crimping wire harness terminals is also provided, including...

[0045] Different specifications of wire harnesses are threaded into the corresponding inlet pipe 11, and the ends of the wire harnesses are clamped by the clamping structure.

[0046] The upper and lower control structure 2 controls the wire frame 1 to move up and down, thereby controlling the preset inlet pipe 11 to align with the transmission roller 3;

[0047] The clamping structure loosens the wire harness of the pre-set inlet tube 11;

[0048] The transmission roller 3 contacts the wire harness inside the preset inlet tube 11 and controls the rotation of the transmission belt, so that the wire harness moves inside the preset inlet tube 11.

[0049] If it is necessary to switch to a different wiring harness, the drive belt will stop rotating and will separate from the original wiring harness.

[0050] The clamping structure is controlled to clamp the original wire harness;

[0051] The upper and lower control structure 2 controls the wire frame 1 to move up and down, thereby controlling the alignment of the inlet pipe 11 corresponding to the wire harness to be switched with the transmission roller 3;

[0052] The clamping structure will loosen the wire harness of the inlet pipe 11 after switching;

[0053] The transmission roller 3 contacts the wire harness inside the switched inlet pipe 11 and controls the rotation of the transmission belt, so that the wire harness moves inside the switched inlet pipe 11.

[0054] Initially, all wire harnesses in the inlet tubes can be clamped by the clamping structure, which facilitates the initial wire threading. After the initial threading, the ends of all wire harnesses in the inlet tubes will not move. When wire feeding is required, the corresponding inlet tube 11 is controlled to move to the alignment position of the transmission roller 3. The clamping claws and other structures at the lower station fix the ends of the wire harness. The clamping structure is controlled by releasing the cylinder 5, and then the transmission roller 3 is controlled to feed the wire harness. When it is necessary to switch the wire harness in different inlet tubes 11, the transmission belt of the transmission roller 3 needs to be stopped first. Then, the top rod 51 of the cylinder 5 is released to separate from the clamping structure, so that the clamping structure clamps the original wire harness. Then, the upper and lower control structure 2 is controlled to move the wire frame 1 up and down, and the alignment and leveling work is repeated to complete the switching of wire harnesses in different inlet tubes 11.

[0055] In this process, because multiple inlet tubes 11 are set, multiple identical or different wire harnesses can be set during use. Different inlet tubes 11 can be switched according to actual production needs, thereby ensuring the stability of the wire feeding process and the fully automated process. There is no need for frequent manual replacement of wire reels, reducing the time for wire reel replacement and improving product production efficiency.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
