Description

Technical Field

[0001] The utility model relates to the technical field of cable terminal processing, in particular to an outer conductor cutting-through device. Background Art

[0002] When processing communication cables, it is often necessary to crimp the outer conductor onto the cable. When crimping, the cable needs to be inserted into the outer conductor to a set depth before crimping to ensure product consistency.

[0003] In the related art, when crimping the outer conductor, the method often used is to move the terminal block to the crimping position, and then use the wire feeding mechanism to insert the cable into the interior of the cable, and crimp it after extending it a set distance; when crimping the above-mentioned threading method, the terminal needs to be cut and crimped at the same time, that is, the outer conductor is cut off from the terminal block, and the outer conductor is crimped at the same time, so that the bare wire and the outer conductor are crimped together.

[0004] However, the inventors have found that the above-mentioned operation method will cause the terminal to be displaced and shaken to a certain extent when being cut, thereby failing to ensure the consistency of the distance that the cable penetrates into the interior of the outer conductor. Summary of the invention

[0005] In view of at least one of the above technical problems, the utility model provides an outer conductor cutting device, which adopts structural improvement to improve the consistency of the distance of the cable penetrating into the outer conductor.

[0013] In some embodiments of the present invention, the in-position detector is a photoelectric sensor, and the photoelectric sensor transmits a signal toward the position of the outer conductor corresponding to the cutting mechanism.

[0014] In some embodiments of the utility model, the cutting mechanism includes a vertical driving member, a shearing seat connected to the vertical driving member, and a support platform arranged opposite to the shearing seat, the support platform has an arc-shaped groove adapted to the contact surface of the outer conductor, the shearing seat has a through groove for the terminal row to pass through, and the through groove and the support platform form a shearing structure.

[0015] In some embodiments of the present invention, the cutting mechanism further includes a waste collection mechanism, and an inlet of the waste collection mechanism is arranged opposite to the cutting mechanism.

[0016] In some embodiments of the present invention, the longitudinal driving member is arranged toward the wire clamping mechanism, and has a movable seat on the longitudinal driving member, the rotating driving member is fixed on the movable seat, and the rotating angle of the rotating driving member is 90 degrees.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] like Figures 1 to 8 The outer conductor cutting and piercing device shown in the figure comprises a material discharging mechanism 1, a conveying mechanism 2, a cutting mechanism 3, a clamping and transferring threading mechanism 4 and a clamping mechanism 5, as shown in FIG. Figure 1 and Figure 2 As shown in, in some embodiments of the utility model, the unwinding mechanism 1 is arranged in a roll shape, and is used to unwind the rolled terminal row; the unwinding of the terminal row is the prior art in this field, and it will not be described in detail here; the conveying mechanism 2 is arranged at the unwinding position of the unwinding mechanism 1, and is used to move the terminal row in sequence according to the outer conductor spacing; it should be pointed out here that the conveying mechanism 2, as the power of the unwinding mechanism 1, mostly includes a linear reciprocating moving part and a material-diverting part connected to the linear reciprocating moving part, and the material-diverting part is connected to the linear reciprocating moving part by a spring, so that when moving in the positive direction, the terminal row is pushed to move a distance of the spacing, and when moving in the reverse direction, the spring does not work, so that the material-diverting part retreats to a position of the spacing of the outer conductor, and the conveying mechanism 2 is the prior art in this field, and its specific structural form is not described in detail here;

[0033] The cutting mechanism 3 is arranged in the moving direction of the terminal block, and is used to cut off a single terminal from the terminal block; that is, the outer conductor conveyed to the cutting mechanism 3 is cut off from the terminal block. It should be pointed out here that before the outer conductor is cut off, the clamping transfer threading mechanism 4 has already clamped the outer conductor to be cut off to avoid the movement of the outer conductor after cutting.

[0034] For the specific structure of the clamping transfer threading mechanism 4, please refer to Figure 6 and Figure 7 , comprising a clamping assembly 41, a rotating driving member 42 and a longitudinal driving member 43, wherein the longitudinal driving member 43 is connected to the rotating driving member 42, and the rotating driving member 42 is connected to the clamping assembly 41, and is used to clamp the outer conductor cut off from the terminal block for transfer; that is, after clamping the outer conductor to be cut off, the clamping assembly 41 is rotated by the rotating driving member 42, and then moved toward the clamped cable by the longitudinal driving member 43, so that the end of the cable is inserted into the outer conductor;

[0035] The clamping mechanism 5 is arranged at a relative position after the clamping transfer threading mechanism 4 is transferred. The clamping assembly 41 has a GT detector 41a. The longitudinal drive member 43 drives the clamping assembly 41 to move toward the cable, and stops when the cable penetrates to the set distance of the outer conductor. The clamping mechanism 5 clamps the cable and the outer conductor synchronously. It should be pointed out here that the GT detector 41a is a prior art in the field of cable detection, and the moving distance of the cable is detected by moving the probe. In the embodiment of the utility model, the outer conductor is clamped and threaded, and the distance of the cable penetrated into the inner part of the outer conductor is detected by the GT detector 41a. After the detection is in place, the cable and the outer conductor are clamped synchronously to ensure the consistency of the cable penetration depth.

[0036] When the outer conductor cutting device in the embodiment of the utility model is in operation, Figure 2 As shown in, first, under the reciprocating movement of the conveying mechanism 2, the terminal row of the outer conductor is unwound, so that the outer conductor is conveyed to the cutting mechanism 3 in turn. At this time, the clamping assembly 41 on the clamping transfer threading mechanism 4 has reached the position relative to the cutting mechanism 3 to clamp the outer conductor to be cut. After the outer conductor is cut off, the rotating driving member 42 rotates so that the outer conductor is directed toward the clamping mechanism 5. At this time, the wire harness with insertion has been clamped and the free end is directed toward the outer conductor. Then the longitudinal driving member 43 moves toward the cable, so that the cable extends into the outer conductor. At the same time, the GT detector 41a starts to detect the depth of the cable inserted into the outer conductor. When the penetration depth reaches the designed distance, it stops. Finally, the clamping mechanism 5 clamps the cable and the outer conductor synchronously, thereby ensuring that the depth of cable insertion is fixed, thereby improving the consistency of the depth of the cable inserted into the outer conductor.

[0037] In the above embodiment, the outer conductor is first cut off from the terminal block by the cutting mechanism 3, and at the same time, the outer conductor is clamped by the clamping and transferring threading mechanism 4 and transferred to the clamping mechanism 5. The longitudinal driving member 43 drives the cable to penetrate into the outer conductor, and the depth of the cable penetrating into the outer conductor is detected by the GT detector 41a on the clamping assembly 41. Finally, the cable is clamped by the clamping mechanism 5. Through the above arrangement, compared with the prior art, the consistency of the depth of the cable penetrating into the outer conductor is improved, thereby improving the reliability of subsequent product processing.

[0038] Based on the above examples, please continue to refer to Figure 3In the embodiment of the utility model, in order to ensure the reliability of each cutting and clamping position, there is also an in-position detector between the conveying mechanism 2 and the cutting mechanism 3, which is used to detect whether the outer conductor reaches the position of the cutting mechanism 3. Of course, it should be pointed out here that in some embodiments of the utility model, the device for in-position detection has various forms, such as a laser detector, a travel switch, etc. In the embodiment of the utility model, the in-position detector is a photoelectric sensor, which emits a signal toward the outer conductor position corresponding to the cutting mechanism 3. Whether the position is correct is determined by transmitting and receiving the signal.

[0039] In the embodiment of the present utility model, please refer to the specific structural form of the cutting mechanism 3. Figure 3 and Figure 5 The cutting mechanism 3 includes a vertical driving member 31, a shearing seat 32 connected to the vertical driving member 31, and a support platform 33 arranged opposite to the shearing seat 32. The support platform 33 has an arc groove 33a adapted to the contact surface of the outer conductor, and the shearing seat 32 has a through groove 32a for the terminal row to pass through. The through groove 32a and the support platform 33 form a shearing structure. Figure 4 and Figure 5 As shown in , through this arrangement, the connection between the outer conductor and the terminal block is exactly between the shear seat 32 and the support platform 33, and the vertical drive member 31 is used to drive the shear seat 32 to move downward relative to the support platform 33, thereby achieving shearing at this position and cutting the outer conductor from the terminal block. In addition, in order to further improve the continuity of the work, in the embodiment of the utility model, the cutting mechanism 3 also includes a waste collection mechanism 34, and the entrance of the waste collection mechanism 34 is arranged opposite to the cutting mechanism 3. Figure 3 As shown in FIG. 1 , the remaining portion of the terminal row with the outer conductor cut off is transported to the waste collection mechanism 34 , where the waste collection mechanism 34 may be a collection box, or a winding device, etc.

[0040] Please continue to refer to Figure 6 and Figure 7 In the embodiment of the utility model, the longitudinal driving member 43 is arranged toward the clamping mechanism 5, and the longitudinal driving member 43 has a moving seat, the rotating driving member 42 is fixed on the moving seat, and the rotating angle of the rotating driving member 42 is 90 degrees. Through such an arrangement, the space occupied by the device can be reduced. Since the overall length of the clamping assembly 41 after clamping the outer conductor increases after rotating 90 degrees, the driving distance of the longitudinal driving member 43 is also reduced. In some embodiments of the utility model, in order to improve the driving accuracy, the longitudinal driving member 43 can adopt a motor screw structure.

[0041] Please refer to Figure 8In the embodiment of the utility model, the clamping assembly 41 includes two clamping jaws 41b that can be relatively close or far away, and the opposite surfaces of the clamping jaws 41b have clamping grooves 41b1 that are adapted to the outer surface of the outer conductor. By setting the clamping grooves 41b1, the reliability of clamping can be improved, the accuracy of clamping can be ensured, and the shaking of the outer conductor during the clamping process can be prevented; in the embodiment of the utility model, the clamping assembly 41 also has a transmission member 41a1, which is arranged inside the clamping center of the clamping jaw 41b, and the transmission member 41a1 can be arranged relative to the clamping jaw 41b, and the end of the transmission member 41a1 away from the clamping jaw 41b is connected to the probe of the GT detector 41a. Through such a setting, after the cable end is inserted into the outer conductor, the transmission member 41a1 is driven to retreat by contact with the transmission member 41a1, so that the GT detector 41a can sense the distance of the cable extending into the inner part of the outer conductor.
