The terminology used in the description of the application herein is for the purpose of describing the particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0040] The outer conductor cutting device shown in Figs. 1 to 7 includes a cutting feeding mechanism 1, a moving cutting mechanism 2, and a clamping supporting mechanism 3. As shown in Fig. 1, the cutting feeding mechanism 1 includes a pushing assembly 11 for moving the terminal row, a cutting assembly 12 arranged in the direction of movement of the terminal row, and a placing seat 13 arranged in the opposite direction of the cutting assembly 12 for placing the outer conductor. It should be noted that the pushing assembly 11 is a prior art, which moves the terminal row by a distance of the interval of the outer conductor each time by swinging the wedge-shaped pushing piece, to realize the movement of the terminal row where the outer conductor is located.

[0041] The moving cutting mechanism 2 is arranged on one side of the cutting feeding mechanism 1 and includes a sliding seat 21 which can reciprocate in a direction parallel to the direction of movement of the terminal row, a wire moving driving piece 22 for driving the sliding seat 21 to move, a clamping piece 23 arranged on the sliding seat 21, and a rotating driving piece 24 connected with the clamping piece 23 for driving the clamping piece 23 to change direction.

[0042] The clamping mechanism 3 is arranged opposite to the distal end of the moving direction of the clamping piece 23, and includes a wire clamping piece 31 for clamping the cable;

[0043] Wherein, when the rotating driving piece 24 rotates the clamping piece 23 to the first angle, the clamping piece 23 is arranged towards the placing seat 13, and when the rotating driving piece 24 rotates the clamping piece 23 to the second angle, the clamping piece 23 is arranged towards the wire clamping piece 31; when the threading driving piece 22 drives the sliding seat 21 to the first position, the clamping piece 23 corresponds to the placing seat 13, and when the threading driving piece 22 drives the sliding seat 21 to the second position, the clamping piece 23 penetrates the outer conductor into the center needle on the cable. As shown in FIG. 1, when in the first position, the clamping piece 23 is rotated to the first angle, so that the clamping piece 23 clamps the outer conductor on the placing seat 13, and when the clamping piece 23 is rotated to the second angle, the outer conductor which has been cut off is moved to the direction coaxial with the cable in the axial direction, and is moved towards the cable so as to penetrate the outer conductor into the center needle on the cable.

[0044] In the above embodiment, by cutting off the outer conductor from the terminal row first, and then penetrating the outer conductor into the cable, compared with the prior art, the cutting off of the outer conductor and the subsequent penetrating action are separated, that is, the cutting operation and the subsequent penetrating operation do not affect each other, thereby improving the accuracy of the outer conductor penetration.

[0045] Please refer to FIG. 2, on the basis of the above embodiment, in order to further ensure the reliability and accuracy of the terminal row movement, the cutting and feeding mechanism 1 further has an identification mechanism 14, including a fixed frame 14a fixed on both sides of the material pushing assembly 11 and a laser sensor 14b fixed on the fixed frame 14a, the laser sensor 14b is arranged towards the terminal row. Through the arrangement of the laser sensor 14b, it can be detected whether the outer conductor is in place, and here towards the terminal row specifically refers to being arranged towards the outer conductor on the terminal row, since the outer conductors are arranged at intervals, when the laser is blocked, it indicates that the outer conductor is in place. Please continue to refer to FIG. 2, in some embodiments of the present application, the laser sensor 14b includes a first sensor 14b1 arranged towards the placing seat 13 and a second sensor 14b2 arranged towards the terminal row on the incoming side of the material pushing assembly 11. The first sensor 14b1 is used to detect whether the outer conductor reaches the position of the placing seat 13, and the second sensor 14b2 is used to detect whether the terminal row is out of stock, when the first sensor 14b1 detects that there is an outer conductor on the placing seat 13 and the second sensor 14b2 does not detect an outer conductor, it indicates that the terminal row is about to run out, at this time, an out-of-stock alarm is issued. In addition, in some embodiments of the present application, in order to avoid the waste after the outer conductor is cut off from blocking the terminal row, as shown in FIG. 2, the cutting and feeding mechanism 1 further has a material guide pipe 15, one end of the material guide pipe 15 is towards the material pushing assembly 11, and the other end extends to a waste box, which is used for discharging the waste of the terminal row.

[0046] Please refer to Figure 3, in some embodiments of the present application, in order to further improve the precision of the outer conductor penetration, the sliding seat 21 also has a depth detection mechanism 25 for detecting the distance between the center needle and the end of the outer conductor. As shown in Figure 5, the depth detection mechanism 25 includes a probe 25a, a GT detector 25b connected to the probe 25a, and a detection driving member 25c for driving the probe 25a to move towards the cable direction, the probe 25a is located at the center position of the two jaws when the wire clamping member 31 is turned to the second angle. In this way, after the outer conductor penetration is completed, the probe 25a and the GT detector 25b are driven by the detection driving member 25c to move towards the outer conductor, and after the probe 25a contacts the outer conductor, the distance between the center needle and the edge of the outer conductor is determined according to the movement distance of the probe inside. The GT detector 25b is a prior art, and its internal structure will not be described in detail here; in addition, various driving members in the embodiments of the present application are prior art, such as motor screw structure or linear driving structure such as air cylinder, etc., which will not be described in detail here.

[0047] As shown in Figures 4, 6 and 7, in some embodiments of the present application, the cable is a double-core cable, the outer conductor is a double-hole structure, and the clamping and supporting mechanism 3 further has a supporting assembly 32 arranged on the wire clamping member 31 towards the direction close to the penetrating mechanism 2, the supporting assembly 32 has a wire separating member 32a arranged to move towards the center direction of the double-core wire, and the wire separating member 32a is used to separate the distance between the two wire cores to correspond to the two hole positions of the outer conductor. In this way, by separating the two wire cores with the wire separating member 32a, the distance between the two wire cores corresponds to the hole positions on the outer conductor, so as to improve the success rate of the wire penetration.

[0048] Further, please continue to refer to Figure 6, the supporting assembly 32 further includes a transverse clamping assembly 32b arranged on both sides of the wire separating member 32a in the horizontal direction, and the distance between the transverse clamping assembly 32b after closing corresponds to the maximum transverse distance when the two core wires are inserted. The supporting assembly 32 further includes a longitudinal clamping assembly 32c arranged on both sides of the wire separating member 32a in the vertical direction of the wire insertion position, and the distance between the longitudinal clamping assembly 32c after closing is the same as the diameter of the two core wires. In this way, by clamping in the transverse and longitudinal directions, the movement direction of the two wire cores after the wire separating member 32a is inserted is limited, and the two wire cores of the two core wires are arranged in parallel and spaced apart, as shown in Figure 7. By this arrangement, when the outer conductor is penetrated, the two wire cores correspond to the two hole positions in the outer conductor.

[0049] In the embodiments of the present application, the cutting method of the above-mentioned outer conductor cutting device is also improved, as shown in Figure 8, including the following steps:

[0050] S10: drive the clamping part 31 to clamp the cable according to the set position; the cable here refers to the cable whose ends have been processed, that is, the cable whose two inner cores have been stripped of the outer sheath and the center conductor has been crimped on the inner core;

[0051] S20: drive the supporting assembly 32 to clamp the two-core cable, so that the longitudinal clamping assembly 32c is clamped on both sides of the two-core cable in the vertical direction, the transverse clamping assembly 32b is clamped on both sides of the two-core cable in the horizontal direction, and the dividing part 32a is inserted into the intermediate position of the two-core cable; as shown in FIG. 7, by such arrangement, the spacing of the two inner cores is fixed, thereby facilitating the subsequent arrangement of the outer conductor;

[0052] S30: drive the material shifting assembly 11 to move the single outer conductor on the terminal row to the placement seat 13;

[0053] S40: drive the clamping part 23 to rotate to the first angle and clamp the outer conductor moved to the placement seat 13;

[0054] S50: drive the cutting assembly 12 to cut the outer conductor moved to the placement seat 13; the shifting and cutting procedures of the outer conductor have been mentioned above and will not be described in detail here; it should be pointed out here that when the clamping part 23 rotates to the first angle, it is in an open state and just rotates to the upper and lower sides of the outer conductor on the placement seat 13, and then the clamping part 23 clamps the outer conductor for subsequent cutting and transferring operations;

[0055] S60: transfer the clamping part 23 to the second angle, and drive the threading driving part 22 to make the outer conductor pass through the center pin of the two-core cable;

[0056] S70: drive the supporting assembly 32 to release the clamping of the two-core cable; the release of clamping here means that the clamping jaws of the transverse clamping assembly 32b and the longitudinal clamping assembly 32c are away from each other, and the dividing part 32a also moves away from the wire core, so that the supporting assembly 32 does not affect the continuous threading of the outer conductor.

[0057] S80: continue to drive the threading driving part 22 to make the outer conductor pass through to the position; it should be pointed out here that the passing through to the position can be detected by the depth detection mechanism 25 in the embodiment of the application, and after passing through to the position, the outer conductor is transferred to the next working procedure for working; by the above arrangement, the threading is more accurate, and the success rate and reliability of the threading are improved.

[0058] Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
