Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire processing technology, and in particular to a multi-wire bundle feeding device. Background Technology
[0002] Currently, there are various packaging methods for wire harness raw materials, mainly two: one is coiled wire packaged on a spool, and the other is a method without a spool as a frame, where the wire is simply wound in circles, also known as uncoiled loose wire. This has led to a variety of wire harness delivery rack designs to accommodate different wire packaging methods. Existing wire harness delivery racks are incompatible with uncoiled loose wire and coiled wire, resulting in low production efficiency due to model changes during production. At the same time, using multiple wire harness delivery racks increases production costs due to the high manufacturing cost of the wire harness delivery racks. Moreover, wires inevitably get tangled, and short-wire inspection is required after use for timely replacement management, which also increases the complexity of each wire harness delivery rack. Therefore, we need a wire harness delivery device that can be compatible with multiple wire packaging methods and can easily inspect and process the wires. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-wire harness feeding device.
[0004] To achieve the above objectives, a multi-wire harness feeding device includes a wire frame, which sequentially comprises a feeding mechanism, a knot detection mechanism, a straightening mechanism, and a wire breakage detection mechanism. The feeding mechanism includes a feeding reel rotatably mounted on the wire frame, with a support plate at the bottom of the feeding reel. The feeding reel is cylindrical and has anti-slip textures on its surface. The knot detection mechanism includes a knot detection frame and a knot sensing component. The knot detection frame is provided with a first sensor and a wire outlet. The knot sensing component includes a knot sensing frame hinged to the knot detection frame. One end of the knot sensing frame has a limiting through hole that allows wire to pass through and restricts knotting. The other end of the knot sensing frame has a first sensing end corresponding to the first sensor. A rotatable pre-tensioning wheel is also provided between the limiting through hole and the first outlet on the knot detection frame.
[0005] Different types of wires can be placed on the feed reel. Since the axis of the feed reel is fixed, the axis of different wires is determined to ensure synchronous feeding, which is compatible with different wire packaging methods. In the knot detection mechanism, the wire passes through the limiting through hole, then is pre-tightened by the pre-tightening wheel, and finally exits through the outlet. The limiting through hole is used to block the knot of the wire. At this time, the continuous feeding of the wire will drag the end of the knot sensing frame with the limiting through hole, causing the first sensing end to move away from its original position. The first sensor cannot detect the first sensing end and will alarm. The automation effect is good, the knot detection mechanism has a simple and convenient structure, low manufacturing cost, and high detection accuracy.
[0006] Preferably, the knot-tying sensor frame is provided with a limiting component, the limiting component has a limiting through hole, the wire inlet end of the limiting through hole is provided with a guide arc surface, and the limiting component is fixed to the knot-tying sensor frame by a threaded connection.
[0007] The guide arc surface facilitates the wire passing through the limiting through hole, and at the same time, the guide arc surface can prevent the wire from being scratched and damaged when entering the limiting through hole. The limiting component adopts a threaded connection, and after long-term use and wear, the limiting component can be directly replaced, saving costs.
[0008] Preferably, the limiting member is also fitted with a straightening plate.
[0009] The wire plate acts as a barrier. When the wire passes through the limiting through hole at high speed or encounters a knot, the wire plate can block the part of the wire outside the limiting through hole, preventing the wire from getting tangled with the knot sensing frame.
[0010] Preferably, the knot detection frame is further provided with limit posts on both sides of the first sensing end.
[0011] The knot-tying sensor uses the lever principle. When a knot appears, drag one end of the knot-tying sensor to drive the first sensing end away from the first sensor position to achieve detection. The limiting post limits the stroke of the first sensing end to prevent the first sensing end from moving excessively and detaching.
[0012] Preferably, the wire breakage detection mechanism includes a wire breakage detection frame and a wire breakage detection block disposed on the wire breakage detection frame. The wire breakage detection block is provided with a through hole through which a wire can pass. The front end of the wire breakage detection block is hinged to the wire breakage detection frame, and a weight plate is provided at the rear end of the wire breakage detection block. The wire breakage detection mechanism also includes a second sensor, and the movement path of the weight plate corresponds to that of the second sensor.
[0013] When a wire passes through a through-hole, it supports the wire breakage detection block. When the wire breaks during transmission, the wire breakage detection block loses its support, and the weighted plate moves downwards due to the center of gravity. When it reaches the position of the second sensor, it is detected by the second sensor and an alarm is triggered, thus performing real-time detection of the wire breakage.
[0014] Preferably, the front end of the wire breakage detection block is provided with an upwardly protruding connecting part that is hinged to the wire breakage detection frame, and the rear end of the wire breakage detection block is provided with an upwardly protruding hammer weight part. The hammer weight piece is fixedly connected to the hammer weight part, so that the center of gravity of the rear end of the wire breakage detection block moves downward in its natural state, and the hammer weight piece corresponds to the second sensor.
[0015] The front end of the wire breakage detection block is connected to the wire breakage detection frame via a connecting part, and the rear end of the wire breakage detection block is equipped with a hammer weight and a hammer weight plate to ensure that the center of gravity is shifted to the rear, so that the rear end of the wire breakage detection block moves downward in its natural state, and the hammer weight plate is detected by the second sensor.
[0016] Preferably, the straightening mechanism includes a straightening frame, on which upper straightening blocks and lower straightening blocks are provided, the upper straightening blocks are provided with multiple rotatable upper straightening wheels, and the lower straightening blocks are provided with multiple lower straightening wheels, the upper straightening wheels and the lower straightening wheels are arranged in a staggered manner.
[0017] The wire is placed between the upper and lower straightening rollers. As the wire passes through, the staggered arrangement of the upper and lower straightening rollers creates a uniform downward pressure on the wire, driving it to straighten.
[0018] Preferably, the lower straightening block is provided with an upwardly extending guide rod, the upper straightening block can move through the guide rod, a buffer spring is sleeved on the guide rod, and the upper straightening block is connected to a handle pressure lock switch that drives its up and down movement and locks it.
[0019] The upper straightening block is fixed in place by a handle locking switch. The guide rod and buffer spring work together to provide a certain buffer space for the upper straightening block, so as to avoid excessive pressure and damage to the wire. Because of the buffer space, it can also be used for multiple different specifications of wire.
[0020] Preferably, the wire frame is also provided with multiple rows of wire distribution holes.
[0021] The multiple rows of branch holes, arranged in a straight line, correspond to the knot detection mechanism, guiding the wires coming out of each mechanism in an orderly manner and preventing them from becoming tangled.
[0022] Compared with the prior art, the beneficial effects of this utility model are:
[0023] This utility model integrates a wire feeding mechanism, a knot detection mechanism, a straightening mechanism, and a breakage detection mechanism sequentially arranged on a wire rack. The wire is fed through the feeding mechanism, the knot detection mechanism detects knots, the straightening mechanism straightens the wire, and the breakage detection mechanism detects breaks. This high level of integration ensures normal wire processing and production. The feeding mechanism features a fixed-axis feeding reel, compatible with various packaging forms such as loose wire without a central axis and coiled wire, achieving multi-functional compatibility production. It offers fast changeover speed, reliable detection devices, and stable operation, improving production efficiency and reducing manufacturing costs. The knot detection mechanism utilizes a lever principle; when knots occur in the wire, it not only blocks wire transmission but also detects them in real time, ensuring smooth production.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0031] This utility model provides a multi-wire harness delivery device, such as... Figures 1-5 As shown, the device includes a wire rack 1, which is equipped with a wire feeding mechanism 2, a knot detection mechanism 3, a straightening mechanism 4, and a wire breakage detection mechanism 5. The wire is fed out through the wire feeding mechanism 2, then the knot detection mechanism 3 detects in real time whether there is a knot in the wire, then the straightening mechanism 4 straightens the wire, and finally the wire breakage detection mechanism 5 detects the wire breakage to ensure smooth production.
[0032] The wire feeding mechanism 2 includes a wire feeding reel 6 rotatably mounted on the wire frame 1. Loose wire without a central spool and coiled wire can be installed on the wire feeding reel 6. For ease of installation, the wire feeding reel 6 is cylindrical and has anti-slip texture 7 on its surface. To prevent the wire from falling downwards, a support plate 8 is provided at the bottom of the wire feeding reel 6. The fixed axis position of the wire feeding reel 6 provides a fixed feeding point for the wire. The wire feeding reel 6 is also compatible with various packaging forms of wire, greatly improving its versatility.
[0033] The knot detection mechanism 3 includes a knot detection frame 9 and a knot sensing component 10. The knot detection frame 9 is equipped with a first sensor 11 and a wire outlet 12. The knot sensing component 10 includes a knot sensing frame 13, which is hinged to the knot detection frame 9. One end of the knot sensing frame 13 is provided with a limiting member 14, which is fixed to the knot sensing frame 13 by a threaded connection. The limiting member 14 is provided with a limiting through hole 15 that allows wire to pass through but restricts knotting. The wire inlet end of the limiting through hole 15 is provided with a guide arc surface 16. The wire passes through the limiting through hole 15 through the guide arc surface 16. The guide arc surface 16 prevents the wire from directly scraping and wearing the limiting through hole 15 during wire transport. The limiting member 14 is threaded, and the limiting member 14 with a limiting through hole 15 of different diameter can be replaced according to the needs of different wires to meet production requirements. The knot detection frame 9 is further equipped with a rotatable pre-tightening wheel 17 between the limiting through hole 15 and the outlet 12. After the wire passes through the limiting through hole 15, it is pre-tightened by the pre-tightening wheel 17 and then output from the outlet 12. The other end of the knot sensing frame 13 is equipped with a first sensing end 18 corresponding to the first sensor 11. The knot detection frame 9 is also equipped with limiting posts 19 on both sides of the first sensing end 18. When the wire becomes knotted, the knot cannot pass through the limiting through hole 15. The wire continues to pull one end of the knot sensing frame 13 with the limiting member 14. Since the middle of the knot sensing frame 13 is hinged to the knot detection frame 9, according to the lever principle, the first sensing end 18 will disengage from its original position. The first sensor 11 will not receive the signal from the first sensing end 18, thus achieving detection. The function of the limiting posts 19 is to limit the travel of the first sensing end 18. The first sensor 11 can be implemented using any existing technology. The limiting member 14 is also fitted with a wire-aligning plate 20, which acts as a blocking device. When the wire passes through the limiting through hole 15 at high speed or when it encounters a knot and stops, the wire-aligning plate 20 can block the part of the wire outside the limiting through hole 15, preventing the wire from getting tangled with the knot sensing frame 13.
[0034] The wire breakage detection mechanism 5 includes a wire breakage detection frame 21 and a wire breakage detection block 22 disposed on the wire breakage detection frame 21. The wire breakage detection block 22 is provided with a wire through hole 23 through which a wire can pass. The front end of the wire breakage detection block 22 is provided with an upwardly protruding connecting part 24 that is hinged to the wire breakage detection frame 21. The rear end of the wire breakage detection block 22 is provided with a hammer weight plate 25 and an upwardly protruding hammer weight part 26. The hammer weight plate 25 and the hammer weight part 26 are fixedly connected, so that the center of gravity of the wire breakage detection block 22 shifts backward in its natural state, and the rear end of the wire breakage detection block 22 moves downward. The wire breakage detection mechanism 5 also includes a second sensor 27. The movement path of the hammer weight 25 corresponds to that of the second sensor 27. In its natural state, the hammer weight 25 falls into the sensing area of the second sensor 27. When a wire passes through the through hole 23, the wire provides support for the wire breakage detection block 22, ensuring horizontal transmission of the wire. When a wire breakage occurs, the hammer weight 25 loses its support and falls into the sensing area of the second sensor 27, thus realizing the wire breakage detection function. The structure is simple, easy to manufacture, and the detection effect is stable and reliable. The second sensor 27 can be implemented using any existing technology.
[0035] The straightening mechanism 4 includes a straightening frame 28, on which are provided an upper straightening block 29 and a lower straightening block 30 corresponding to each other. The lower straightening block 30 is provided with an upwardly extending guide rod 31. The upper straightening block 29 can move through the guide rod 31. A buffer spring 32 is sleeved on the guide rod 31. The upper straightening block 29 is connected to a handle locking switch 33 that drives its up and down movement and locks it. The upper straightening block 29 is provided with multiple rotatable upper straightening wheels 34, and the lower straightening block 30 is provided with multiple lower straightening wheels 35. The wire passes through the compression between the upper straightening wheels 34 and the lower straightening wheels 35. The upper straightening block 29 is fixed and positioned by the handle locking switch 33. The guide rod 31 and the buffer spring 32 are designed to provide a certain buffer space for the upper straightening block 29 to avoid excessive pressure and damage to the wire. Because of the buffer space, it can also be used for multiple different specifications of wires at the same time. To achieve uniform straightening of the wire, the upper straightening wheel 34 and the lower straightening wheel 35 are staggered to uniformly compress the wire. The handle locking switch 33 can be implemented using any existing technology.
[0036] The wire frame 1 is also provided with multiple rows of wire splitting holes 36. The multiple rows of wire splitting holes 36 can correspond to the knot detection mechanism 3 in a straight line, so as to guide the wires coming out of each knot detection mechanism 3 in an orderly manner and avoid the wires from getting messy.
[0037] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
