Description

Technical Field

[0001] The invention belongs to the technical field of wire harness processing, in particular to an automatic wire harness shell threading device. Background Art

[0002] Wire harness products are often used in consumer electronics products. Wire harness products are used for signal interaction and other functions among different electronic components. During the processing and manufacturing process, the wire harness needs to be penetrated through the shell. After penetration, ensure that the electrical components inside the wire harness and the external covering can be tightly fixed in place to prevent the wire harness from moving or loosening during use.

[0003] A patent with publication number CN117895306B discloses an automatic wire harness threading device. When threading through the shell, the tightening end clamps the end of the wire harness to prevent the end of the wire harness from loosening. When the wire harness is threading through the shell, the tightening end contacts the inner wall of the plastic shell to prevent the wire harness from getting stuck or getting tangled or even getting detached due to friction with the inner wall of the plastic shell, solving the problem of inconsistent length of the wire harness threading through or some cables not being threaded through.

Since the wire harness is made of deformable material, the wire harness may be deformed during the transmission process, and the end of the wire harness may become loose or bent, which will cause the wire harness to be unable to pass through the shell. At this time, the machine needs to be stopped to adjust the wire harness, which is more cumbersome and reduces work efficiency.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Example 1: Figure 1-Figure 4 、 Figure 8 As shown, an automatic wire harness threading device according to an embodiment of the present invention includes a first cylinder 1, a first clamping assembly is provided in the middle of the first cylinder 1, the first clamping assembly includes a plurality of rectangular cylinders 111 rotatably provided on one side of the middle of the first cylinder 1, one end of the rectangular cylinder 111 is elastically connected to a first clamping strip 112, a rectangular frame 12 is fixedly connected to one side of the first cylinder 1, a second cylinder 13 is fixedly connected to one side of the rectangular frame 12, the second cylinder 13 passes through the rectangular frame 12, the second cylinder 13 is located in the middle of the first cylinder 1, and a second cylinder 13 is slidably provided in the middle of the second cylinder 13. The clamping assembly includes a third ring 133 slidably arranged in the middle of the second cylinder 13, and a plurality of second rectangular bars 1331 are fixedly connected to one side of the third ring 133. The ends of the second rectangular bars 1331 are respectively rotatably connected to the second clamping bars 1332. The first cylinder 1 is provided with a third clamping assembly on the side away from the rectangular frame 12. The third clamping assembly includes a first clamping block 2, and a second clamping block 21 is provided on the upper end of the first clamping block 2. A cylindrical bar 211 is fixed to one side of the upper end of the first clamping block 2, and the cylindrical bar 211 passes through the second clamping block 21.

[0023] Specifically, in the process of wiring harness assembly, threading and fixing the wire harness is an important step to ensure the stability and safety of the wire harness. In the prior art, when threading the wire harness through the shell, the wire harness end is generally clamped and then sent into the shell. When the wire harness is sent into the shell, the wire harness end needs to be kept straight and compact before it can be inserted into the shell. Since the wire harness is made of deformable material, when the wire harness is continuously threaded through the shell, the wire harness may be deformed during the transmission process, and the wire harness end may become loose or bent. It needs to be adjusted continuously before it can be inserted into the shell. When using the automatic wire harness shell-penetrating device, the shell is placed between the first clamping block 2 and the second clamping block 21 for clamping, and then the end of the wire harness is transferred to the middle of the second cylinder 13 until it is located in the middle of the first clamping strips 112. Then, the rectangular cylinders 111 are driven to rotate at the same time. The rotation of the rectangular cylinder 111 drives the first clamping strips 112 to rotate inward at the same time, so that the first clamping strips 112 slide into the interior of the rectangular cylinder 111 at the same time. The first clamping strips 112 rotate inward. At the same time, the middle end of the wire harness is clamped and squeezed, and the rectangular cylinder 111 continues to rotate to drive the first clamping bar 112 to move closer to the second clamping bar 1332. The first clamping bar 112 drives the wire harness clamped in the middle to approach the second clamping bar 1332, which can squeeze and straighten the end of the wire harness to keep it compact and straight. Until the end of the wire harness is pulled to the middle of the second clamping bar 1332, the second clamping bar 1332 clamps the wire harness, and then drives the third ring 133 to slide in the middle of the second cylinder 13 toward the side close to the shell. The third ring 133 drives the second clamping bar 1332 through the second rectangular bar 1331 to drive the wire harness clamped in the middle to approach the shell until the end of the wire harness is inserted into the shell. The first clamping bar 112 is driven to clamp and squeeze the end of the wire harness, and the wire harness is pulled to the middle of the second clamping bar 1332. Then, the second clamping bar 1332 drives the wire harness to be plugged into the shell. Before each wire harness is passed through the shell, it is squeezed and pulled to reduce the phenomenon that the wire harness cannot be passed through the shell due to loose bending, reduce the number of shutdown adjustments, and improve work efficiency.

[0024] like Figure 3 As shown, a second ring 131 is fixedly connected to one side of the second cylinder 13 , and a conical cylinder 132 is fixedly connected to the side of the second ring 131 close to the second cylinder 13 . The conical cylinder 132 is located in the middle of the second cylinder 13 .

[0025] Specifically, when the wiring harness is placed inside the second cylinder 13, since the opening of the conical cylinder 132 at one end close to the first clamping bar 112 is smaller, the end of the wiring harness moves through the conical cylinder 132 to the middle of several first clamping bars 112, so that the end of the wiring harness can be located in the middle of several first clamping bars 112, making it convenient for the first clamping bar 112 to clamp the wiring harness.

[0026] like Figure 3-Figure 4As shown, the second rectangular bar 1331 is connected to the second clamping bar 1332 through a torsion spring, and the first clamping bars 112 are respectively located between two adjacent second clamping bars 1332 . The first clamping bar 112 is connected to the inside of the rectangular tube 111 through the first spring 113 .

[0027] Specifically, when the rectangular tube 111 drives the first clamping bar 112 to rotate and clamp the wire harness, the first clamping bar 112 simultaneously slides toward the inside of the rectangular tube 111 and squeezes the first spring 113. The first clamping bar 112 simultaneously squeezes the wire harness in the middle until the end of the wire harness is moved between several second clamping bars 1332 for clamping.

[0028] like Figure 4 As shown, the first clamping strip 112 is L-shaped, and a plurality of arc-shaped protrusions 1121 are fixedly connected to the outer sides of the bending parts of the first clamping strips 112 .

[0029] Specifically, when the first clamping bar 112 clamps the wire harness, a number of arc-shaped protrusions 1121 are provided on the outer side of the fold of the first clamping bar 112 to contact the side of the wire harness. The arc-shaped protrusions 1121 are made of soft rubber material, which can increase the friction between the wire harness and the first clamping bar 112 to prevent the wire harness from slipping.

[0030] like Figure 5 As shown, several groups of transmission wheels are provided inside the rectangular frame 12, and the transmission wheels include first rectangular bars 121 fixed on both sides of the rectangular frame 12, and waist-shaped blocks 122 are fixed on the opposite sides of the first rectangular bars 121. Two arc-shaped rotating wheels 123 are rotatably connected between the two waist-shaped blocks 122.

[0031] Specifically, the end of the wire harness is placed between several groups of arc-shaped wheels 123 , which clamp the wire harness to keep it horizontal. Driving the several arc-shaped wheels 123 to rotate can drive the wire harness to be transmitted to the side close to the first cylinder 1 .

[0032] like Figure 6 As shown, a cutting assembly is provided on one side of the rectangular frame 12 near the second cylinder 13, and the cutting assembly includes a first rectangular block 14 fixedly connected to one side of the inner part of the rectangular frame 12, a circular hole 141 is opened in the middle of the first rectangular block 14, and blades 142 are respectively provided on the upper and lower sides of the first rectangular block 14 for sliding. The blades 142 can slide inside the first slide rail 143 respectively, and the first slide rail 143 is fixed to one side of the inner part of the rectangular frame 12.

[0033] Specifically, the bundled wire harness end is placed between the arc-shaped rotating wheels 123 for transmission. When the end is completed through the shell, the two blades 142 are driven to slide simultaneously in the first slide rail 143 toward the middle of the first rectangular block 14 to cut the wire harness. The cut and shell-mounted wire harness section is then taken away. At this time, the end of the rolled wire harness is located in the middle of the arc-shaped rotating wheel 123. The arc-shaped rotating wheel 123 is driven to rotate to drive the end of the rolled wire harness to move toward the side close to the first cylinder 1, and the shell-piercing work is performed again. The shell-piercing work can be performed continuously.

[0034] like Figure 8 As shown, the upper end of the cylindrical bar 211 is fixedly connected to a second rectangular block 212, the lower end of the second rectangular block 212 is fixedly connected to the second clamping block 21 through a first electric telescopic rod 213, the upper end of the second rectangular block 212 and the lower end of the first clamping block 2 are respectively slidably connected to a second slide rail 22, and the end of the second slide rail 22 away from the first cylinder 1 is fixedly connected through a fourth rectangular block 221.

[0035] Specifically, when the end of the wiring harness is plugged into the shell, the first electric telescopic rod 213 is driven to extend, driving the second clamping block 21 to move toward the side close to the first clamping block 2, squeezing the middle shell to make the shell and the wiring harness fit more closely, preventing the wiring harness from falling off.

[0036] like Figure 7 、 Figure 9 As shown, a collection frame 24 is fixedly connected to one side of the second slide rail 22 at the lower end, a slider 23 is slidingly arranged between the two second slide rails 22, a screw rod 231 is threadedly connected to the upper end of the slider 23, an L-shaped bar 232 is fixed to the side of the slider 23 away from the collection frame 24, and a second electric telescopic rod 2321 is fixed to the side of the L-shaped bar 232 close to the collection frame 24, and a push block 2322 is fixed to the output end of the second electric telescopic rod 2321.

[0037] Specifically, after the wiring harness is plugged into the shell, the first clamping block 2 is driven to slide at the upper end of the second slide rail 22 to pull out the wiring harness. After pulling out to a suitable length, the wiring harness is cut off by driving the slider 23 to slide on the second slide rail 22. After sliding to a suitable distance, the screw rod 231 is driven to rotate so that the screw rod 231 is against one side of the second slide rail 22, so that the slider 23 can remain stationary. The sliding distance of the first clamping block 2 can be controlled, and the length of the wiring harness pulled out can be adjusted. After the wiring harness passes through the shell and is cut off, the second electric telescopic rod 2321 is driven to extend and the push block 2322 is driven to move toward the side of the collection frame 24, pushing the wiring harness that has passed through the shell into the collection frame 24.

[0038] like Figure 9As shown, a third rectangular block 233 is fixed to the side of the slider 23 away from the L-shaped bar 232, and the third rectangular block 233 can slide on the upper end of the collection frame 24. An L-shaped plate 2331 is slidingly provided on one side of the third rectangular block 233, and the L-shaped plate 2331 is rotatably connected to a rectangular plate 2332 at the lower end close to the slider 23.

[0039] Specifically, the second electric telescopic rod 2321 is driven to extend to drive the push block 2322 to push the wire harness after the shell is passed through to the upper end of the L-shaped plate 2331, and then the rectangular plate 2332 is driven to rotate at the lower end of the L-shaped plate 2331, so that the wire harness falls into the collection frame 24. By driving the L-shaped plate 2331 to slide on one side of the third rectangular block 233, the wire harness can be arranged in sequence and placed in the collection frame 24 to prevent the wire harness from stacking and entanglement.

[0040] Example 2: Figure 1 As shown, compared with Example 1, another embodiment of the present invention is: the lower end of the rectangular frame 12 is fixedly connected to the bottom plate 3, the collection frame 24 is fixedly connected to the bottom plate 3, and the upper end of the bottom plate 3 is fixedly connected to the side away from the collection frame 24 with two support columns 4.

[0041] Specifically, before processing, the rolled wire harness is installed between two support columns 4, and then the end of the wire harness is pulled out for continuous processing.

[0042] Working principle: before processing, the shell is placed between the first clamping block 2 and the second clamping block 21 for clamping, and then the rolled wire harness is installed between the two support columns 4, and the bundled wire harness ends are placed between the arc-shaped wheels 123 for transmission. When the wire harness is transmitted to the inside of the second cylinder 13, since the opening of the conical cylinder 132 at one end close to the first clamping strip 112 is smaller, the wire harness end passes through the conical cylinder 132 and moves to the middle of the first clamping strips 112, and then drives the rectangular cylinders 111 to rotate at the same time. The rotation of the rectangular cylinder 111 drives the first clamping strips 112 to rotate inward at the same time, so that the first clamping strips 112 slide into the inside of the rectangular cylinder 111 at the same time. The first clamping strip 112 rotates inward and clamps and squeezes the middle wire harness end at the same time. The rectangular cylinder 111 continues to rotate to drive the first clamping strip 112 Move toward the side close to the second clamping bar 1332, the first clamping bar 112 drives the wire harness clamped in the middle to approach the second clamping bar 1332, which can squeeze and straighten the end of the wire harness to keep the wire harness compact and straight, until the end of the wire harness is pulled to the middle of the second clamping bar 1332, and the wire harness is clamped by the second clamping bar 1332, and then the third ring 133 is driven to slide in the middle of the second cylinder 13 toward the side close to the shell, and the third ring 133 drives the second clamping bar 1332 to drive the wire harness clamped in the middle to approach the shell through the second rectangular bar 1331, until the end of the wire harness is inserted into the shell. When the end of the wire harness is plugged into the shell, the first electric telescopic rod 213 is driven to extend, driving the second clamping block 21 to move toward the side close to the first clamping block 2, squeezing the shell in the middle to make the shell and the wire harness fit more closely; By driving the L-shaped plate 2331 to slide on one side of the third rectangular block 233, the wire harness can be arranged in sequence and placed in the collection frame 24 to prevent the wire harness from being stacked and entangled.
