[0034] Embodiment one

[0035] As Figures 1-4As shown, the cable taking-out device provided by the embodiment of the present application comprises at least one set of cable taking-out devices, each set of cable taking-out devices comprises a feeding drum 11, a feeding assembly 12, a cutting assembly 13 and an infrared distance measuring assembly 14, wherein the feeding drum 11 is internally provided with a through cavity; the feeding assembly 12 is used to deliver the bundled cable 100 into the through cavity, and the feeding assembly 12 feeds in accordance with the set feeding length; the cutting assembly 13 is arranged on the feeding drum 11 and can cut off the cable 100 by extending into the through cavity; the infrared distance measuring assembly 14 comprises an infrared distance measurer and a sliding block 141, the sliding block 141 is slidingly arranged in the through cavity, and the cable 100 can push the sliding block 141 to move when being delivered in the through cavity; the distance between the sliding block 141 and the cutting assembly 13 is the actual feeding length of the cable 100, the infrared distance measurer can measure the distance between the cutting assembly 13 and the sliding block 141 to review the feeding length of the feeding assembly 12, and when the actual feeding length measured by the infrared distance measurer is consistent with the set feeding length, it indicates that the feeding assembly 12 does not slip with the cable 100, and the cutting assembly 13 can cut the cable 100.

[0036] The cable taking-out device can review the feeding length of the feeding assembly 12 by arranging the infrared distance measuring assembly 14 to determine whether the actual feeding length is consistent with the set feeding length, thereby avoiding the waste of the cable 100 due to the failure of the feeding assembly 12.

[0037] Specifically, the sliding block 141 is slidingly arranged in the through cavity and elastically connected with the feeding drum 11, and the sliding block 141 always has a movement trend towards the cutting assembly 13 under the elastic force, when the feeding assembly 12 drives the cable 100 to be delivered, the cable 100 can overcome the elastic force to push the sliding block 141 to move, and after the cutting assembly 13 cuts off the cable 100, the cut-off cable 100 falls, and the sliding block 141 moves towards the cutting assembly 13 under the elastic force to reset.

[0038] Optionally, an end cover is arranged at the end of the feeding drum 11 away from the cutting assembly 13, a first elastic member is arranged between the sliding block 141 and the end cover, and the two ends of the first elastic member abut against the sliding block 141 and the end cover respectively, so that the cable 100 can overcome the elastic force of the first elastic member to move the sliding block 141 when pushing the sliding block 141 to move.

[0039] Optionally, the first elastic member can be but is not limited to a compression spring.

[0040] Optionally, in order to conveniently lead out the cut-off cable 100, a cable outlet groove 111 is arranged on the side wall of the feeding drum 11, the cable outlet groove 111 is located at the bottom of the feeding drum 11 and communicates with the through cavity, and after the cutting assembly 13 cuts off the cable 100, the cable 100 can fall out through the cable outlet groove 111 to facilitate the leading out.

[0041] Further, a take-up box is arranged below the wire inlet cylinder 11, and the take-up box is arranged opposite to the wire outlet slot 111. When the cut cable 100 falls out of the wire outlet slot 111, the cable can be directly accommodated in the take-up box.

[0042] Preferably, each cable taking device further comprises an auxiliary wire pushing assembly, which is arranged downstream of the wire cutting assembly 13 and directly above the wire outlet slot 111. In order to make the cut cable 100 quickly fall into the take-up box after the wire cutting assembly 13 cuts the cable 100, the output end of the auxiliary wire pushing assembly can extend into the through cavity and push the cable 100, so that the cut cable 100 quickly falls, and the wire cutting efficiency is improved.

[0043] Specifically, the auxiliary wire pushing assembly comprises a pushing cylinder and a pushing block. The pushing cylinder is fixedly arranged outside the wire inlet cylinder 11, and the pushing block is fixedly arranged at the output end of the pushing cylinder. After the wire cutting assembly 13 cuts the cable 100, the pushing cylinder can drive the pushing block to extend into the through cavity and push the cable 100. This structure is simple in design, convenient to use and low in cost.

[0044] With reference to the above description, the cable taking device of the present application has the following advantages: Figure 1The infrared distance measuring device includes a distance measuring module 142 and a reflector 143. The distance measuring module 142 is arranged outside the wire inlet cylinder 11 and is arranged in alignment with the wire cutting assembly 13. The reflector 143 is fixedly connected with the sliding block 141, and a part of the reflector 143 extends out through the wire outlet slot 111. The distance measuring module 142 is provided with an infrared emitter and an infrared receiver. The infrared emitter can emit an infrared signal, which is reflected by the reflector 143 and then received by the infrared receiver. The distance measured by the infrared distance measuring device is calculated by the time for the infrared signal to be emitted and received and the propagation speed of the infrared signal. Therefore, the sliding block 141 drives the reflector 143 to move simultaneously. The distance between the distance measuring module 142 and the reflector 143 is measured by the infrared distance measuring device, so that the distance between the sliding block 141 and the wire cutting assembly 13 is obtained, and the length of the cable 100 is calculated. When the actual length of the cable 100 measured by the infrared distance measuring device is inconsistent with the set length, in order to determine the accuracy of the infrared distance measuring device, the side wall of the wire inlet cylinder 11 is further provided with a scale. The staff can directly observe the distance between the distance measuring module 142 and the reflector 143 on the scale, and then obtain the actual length of the cut cable 100. If the actual length of the cable 100 displayed by the scale is consistent with the length of the cable 100 measured by the infrared distance measuring device, it indicates that the wire inlet assembly 12 fails when conveying the cable 100. If the actual length of the cable 100 displayed by the scale is inconsistent with the length of the cable 100 measured by the infrared distance measuring device, it indicates that the infrared distance measuring device fails, and the infrared distance measuring device needs to be debugged first, and then the subsequent process is performed.
