Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a twisted pair untwisting tool. Background Art

[0002] A twisted pair cable is a cable made of two insulated metal wires twisted together. Since the two insulated wires are twisted together at a certain density, the radio waves radiated by each wire during transmission will be offset by the radio waves emitted by the other wire, thereby effectively reducing signal interference. However, in the actual use of the twisted pair cable, it is necessary to partially or completely untwist it.

[0003] In the prior art, the untwisting of twisted pair wires is mostly achieved by hard pulling. For example, Japanese invention patent with publication number JPH08329751A disclosed a twisted pair wire untwisting clamp and untwisting device on December 13, 1996. The clamp has a slit for inserting the twisted pair wire. When untwisting, the slit is first inserted to the position where the twisted pair wire needs to be untwisted, and then the clamp is pulled toward the free end of the twisted pair wire. Under the action of the pulling force, the part of the twisted pair wire that needs to be untwisted automatically flips, and the two wires are straightened under the action of the pulling force, thereby achieving the untwisting operation of the twisted pair wire.

[0004] However, the inventors have found that the untwisting distance of the untwisting clamp is limited. If the untwisting distance is too long, it is easy to cause damage to the twisted pair, affecting the quality and efficiency of the untwisting. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] 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.

[0029] like Figures 1 to 7 The twisted pair untwisting tool shown comprises an untwisting mechanism 1 and a guide mechanism 2, wherein the guide mechanism 2 comprises a platform 21 and a holding assembly 22, wherein the holding assembly 22 comprises a pressing platform 22a arranged opposite to the platform 21, a guide plate 22b fixed on the pressing platform 22a and extending toward the platform 21, and a first driving member 22c connected to the pressing platform 22a and used for driving the pressing platform 22a to approach or move away from the platform 21; the guide plate 22b has a guide groove 22b1 for the twisted pair damping to pass through;

[0030] The untwisting mechanism 1 includes a rotating component 11, a clamping component 12 arranged at the end of the rotating component 11, and a linear drive component 13 that drives the rotating component 11 to move toward or away from the guide mechanism 2; wherein, the untwisting mechanism 1 is configured such that after the clamping component 12 clamps the end of the twisted pair, the rotating component 11 rotates in the opposite direction to the twisted pair, and at the same time, the linear drive component 13 drives the clamping component 12 away from the guide mechanism 2.

[0031] In an embodiment of the utility model, the guide plate 22b extends toward the carrier 21. When the twisted pair is placed in place, the guide plate 22b moves toward the twisted pair so that the twisted pair is inserted into the guide groove 22b1. Then the clamping assembly 12 moves to the end of the twisted pair to clamp it. Then the rotating assembly 11 rotates, and the direction of rotation is opposite to the winding direction of the twisted pair, so that the twisted pair is untwisted. At the same time, the linear drive assembly 13 pulls the end of the twisted pair backward, so that the twisted pair behind the guide groove 22b1 continues to untwist. In the embodiment of the utility model, the twisted pair end is clamped by the clamping assembly 12 in the untwisting mechanism 1, and the twisted pair is pulled synchronously when the rotating assembly 11 rotates in the opposite direction, so that the twisted pair passes through the guide groove 22b1 with a certain resistance. Compared with the prior art, not only the untwisting length of the twisted pair is increased, but also the efficiency of the untwisting of the twisted pair is improved, and the damage to the twisted pair is reduced, thereby improving the quality of the untwisting of the twisted pair.

[0032] On the basis of the above embodiment, in order to improve the accuracy of embedding the twisted pair into the guide groove 22b1 each time, as shown in FIG. Figure 3As shown in , the two side walls of the opening of the guide groove 22b1 are set in a flared shape. In this way, when the twisted pair is placed on the carrier 21, the guide plate 22b is allowed to have some deviation during the descent process, and it can still be ensured that the twisted pair can smoothly enter the guide groove 22b1. In addition, in some embodiments of the utility model, in order to ensure that the guide groove 22b1 can play a supporting role for the cable but not cause excessive resistance to affect the passage of the twisted pair, the width of the bottom of the guide groove 22b1 is the center distance between the two conductors of the twisted pair. With such a setting, when the twisted pair is pulled out, the twisted pair will not rotate in the guide groove 22b1, thereby improving the efficiency of untwisting.

[0033] Please continue to refer to Figure 4 In some embodiments of the present invention, the carrier 21 includes a carrier plate 21a and a movable frame 21b connected to the carrier plate 21a, and the end of the carrier plate 21a and the guide plate 22b are in a shearing structure. That is, the inner wall of the guide plate 22b is close to the outer wall of the carrier plate 21a. Through this structural form, the opening of the guide groove 22b1 is blocked by the end of the carrier plate 21a, forming a closed rectangular hole structure, thereby further preventing the twisted pair from falling off from the guide groove 22b1 during the untwisting process.

[0034] In addition, please continue to refer to Figure 4 In the embodiment of the utility model, in order to further prevent the guide plate 22b from accidentally damaging the twisted pair when it falls, the carrier plate 21a and the moving frame 21b are movably connected, and the moving frame 21b has a guide column 21c movably connected to the carrier plate 21a, and a spring 21d is also sleeved on the guide column 21c. In this way, through the contact of the spring 21d, the carrier plate 21a is pressed and moves downward for a certain distance, forming a flexible contact, thereby improving the protection of the twisted pair.

[0035] In some embodiments of the present invention, in order to further improve the efficiency of untwisting the twisted pair, please continue to refer to Figure 4 The side wall of the moving frame 21b also has a parallel slider 21b1 and a rack 21b2 for conveying the carrier 21. Of course, it should be pointed out that in the embodiment of the utility model, a circulating conveyor line is used, such as the automatic equipment circulation device disclosed in our invention patent with publication number CN111252490A. Through the setting of this structural form, the continuous untwisting operation of multiple twisted pair cables can be realized.

[0036] In some embodiments of the present invention, Figure 5As shown in , the rotating assembly 11 includes a first motor 11a and a rotating shaft 11b connected to the output shaft of the first motor 11a, and the clamping assembly 12 includes a chuck 12a, which is arranged at the free end of the rotating shaft 11b. The rotating shaft 11b is driven to rotate by the first motor 11a. Since the chuck 12a is fixed to the end of the rotating shaft 11b, the first motor 11a drives the chuck 12a to rotate. It should be pointed out here that in the embodiment of the utility model, the material of the chuck 12a is not limited. In order to achieve more reliable clamping and not damage the twisted pair, in some embodiments of the utility model, the chuck 12a can be made of acrylic material or other hard rubber material.

[0037] In some embodiments of the present invention, there are various specific structural forms of the clamping assembly 12, such as Figure 5 and Figure 6 As shown in FIG. 1 , the clamping assembly 12 further includes a drive disk 12b for driving the clamping head 12a to open and close, and a clamping drive assembly 12c for driving the drive disk 12b to move on the rotating shaft 11b. In some embodiments of the utility model, the specific structure of driving the clamping head 12a to open and close by the drive disk 12b is as follows: Figure 7 As shown in the figure, the two jaws of the chuck 12a are hinged in the middle and the tail is rotatably connected with two connecting rods, the other end of the connecting rod is pivotally connected to a rod fixed on the driving disk 12b. Through this structural setting, when the rotating disk moves back and forth, the angle of the jaw changes, thereby realizing the opening or closing of the jaw; of course, it should be pointed out here that there are many structural forms in the prior art for realizing the opening and closing of the jaw by moving the driving disk 12b back and forth, which will not be repeated here.

[0038] In the embodiment of the present utility model, please refer to Figure 6 Since the driving disk 12b moves back and forth on the rotating shaft 11b, in order not to affect the rotation of the rotating shaft 11b, the clamping drive assembly 12c includes a gantry 12c1 which is sleeved on the circumference of the driving disk 12b, and the gantry 12c1 is provided with two groups of rollers 12c2 which are in rolling contact with the front and rear sides of the driving disk 12b, and also includes a cylinder 12c3 connected to the gantry 12c1 for driving the gantry 12c1 to move back and forth. With such an arrangement, when the rotating shaft 11b rotates, the driving disk 12b is driven to rotate, and the rollers 12c2 on the gantry 12c1 always maintain rolling contact with both the front and rear sides of the driving disk 12b, thereby not affecting the rotation of the rotating shaft 11b. In some embodiments of the present utility model, in order to improve the stability when pulling the twisted pair to move, such as Figure 1As shown in the figure, the linear drive assembly 13 includes a second motor 13a, a screw rod 13b connected to the second motor 13a, and a nut seat 13c screwed on the screw rod 13b, and the nut seat 13c is connected to the rotating assembly 11. Through the above arrangement, the rotation of the second motor 13a drives the rotation of the screw rod 13b, and the rotation of the screw rod 13b drives the nut seat 13c to move along the axial direction of the screw rod 13b. This structural form has good stability, which can further improve the stability of the twisted pair when untwisting.

The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
