Description

A wire insertion device, method and HSD second half automatic production line Technical Field

[0001] The present invention relates to the field of cable processing technology, and in particular to a wire plugging device, method and an HSD second half automatic production line. Background Art

[0002] HSD wiring harnesses, or high-speed transmission cables, have four cores. During processing, the outer insulation layer must be stripped first, and then the insulation layers of the four inner cores must be stripped separately. However, since the four cores overlap to a certain extent in the cable diameter direction, the stripping operation is mostly manual.

[0003] In the prior art, for example, the Chinese invention patent application with publication number CN114050464A, published on February 15, 2022, discloses a plug-in device and an automatic production line for the second half of the HSD process. The device automatically separates two of the four wire cores through the action of two ramps and a wedge-shaped block, making way for subsequent core processing without manual intervention.

[0004] However, the inventors found that when the above device inserts the wire core into the slope, it may fail to insert or insert it incorrectly due to angle problems, and the wire sequence of the above wire harness during insertion is random, which reduces the efficiency of subsequent production. Summary of the Invention

[0005] In view of at least one of the above technical problems, the present invention provides a wire insertion device, method and HSD second half automatic production line, which adopt structural improvements to improve the reliability and accuracy of wire core processing.

[0006] According to a first aspect of the present invention, there is provided a wire insertion device, comprising:

[0007] A wire-digging mechanism, comprising a base, straight holes arranged in parallel on the base in a transverse direction, inclined holes arranged in parallel with the straight holes in a longitudinal direction, and a wedge-shaped plate arranged between two adjacent straight holes and the inclined hole;

[0008] A line adjusting mechanism is arranged opposite to the line dialing mechanism, and the line adjusting mechanism comprises a fixing frame, a threading barrel arranged on the fixing frame, and a line dividing assembly inserted into the threading barrel;

[0009] A wire feeding mechanism is arranged toward the wire adjusting mechanism, and is used to clamp the wire bundle after core stripping and insert it into the wire threading barrel of the wire adjusting mechanism until the inner core of the wire bundle is inserted into the straight hole and the oblique hole of the wire adjusting mechanism respectively and stops;

[0010] In which, the inner diameter of the wire threading barrel toward the wire feeding mechanism is flared, and the wire dividing assembly includes a first wire dividing plate and a second wire dividing plate arranged in a cross-shaped manner. A horizontal wire dividing shovel extends forward from the center of the end face of the first wire dividing plate, and a longitudinal wire dividing shovel intersecting with the horizontal wire dividing shovel extends forward from the center of the end face of the second wire dividing plate, and the length of the horizontal wire dividing shovel is greater than the length of the longitudinal wire dividing shovel.

[0011] In some embodiments of the present invention, both sides of the first breakout board and the second breakout board have symmetrically arranged inclined surfaces.

[0012] In some embodiments of the present invention, the threading barrel is relatively rotatably arranged on the fixing frame.

[0013] In some embodiments of the present invention, the first branching plate and the second branching plate are arranged to protrude from the threading barrel on the side facing the wire-diverting mechanism, and the fixed frame is fixed with a visual recognition mechanism arranged toward the protruding parts of the first branching plate and the second branching plate, and also includes a driving mechanism for driving the threading barrel to rotate.

[0014] In some embodiments of the present invention, the surfaces of the first and second breakout boards that are in contact with the cables are painted black, and the surfaces of the first and second breakout boards where the corners are located are painted white.

[0015] In some embodiments of the present invention, the wire feeding mechanism includes a longitudinal drive component arranged toward or away from the wire adjusting mechanism and a rotation drive component connected to the longitudinal drive component and clamping the cable, and the rotation drive component is arranged to rotate synchronously with the wire threading drum.

[0016] According to a second aspect of the present invention, there is also provided a wire insertion method, which is applied to the above-mentioned wire insertion device and comprises the following steps:

[0017] Check whether the cables are in place;

[0018] Identify whether the cable position complies with the set line sequence;

[0019] If the set line sequence is met, the longitudinal drive assembly is driven to continue moving, so that the wire core enters the wire-pulling mechanism;

[0020] If the threading sequence does not meet the set sequence, the threading drum is driven to rotate by the driving mechanism until the set sequence is reached and then the longitudinal driving assembly is driven.

[0021] In some embodiments of the present invention, when identifying whether the cable position conforms to the wire sequence, first detect whether the corners of the first distribution board or the second distribution board are in the center position, and then rotate the threading drum according to the set wire sequence number. The wire sequence numbering method is to number the wire cores in a circumferential direction, and the rotation drive assembly rotates synchronously with the threading drum.

[0022] In some embodiments of the present invention, when the threading barrel is rotated, the rotation angle is θ=(expected number-actual number)*90°+α, α=arcsin(A / R), where A is the distance between the edge close to the center and the center of the first branching plate or the second branching plate, and R is the outer diameter of the threading barrel.

[0023] According to a third aspect of the present invention, there is also provided an HSD second half automatic production line, comprising a wire insertion device as described in any one of the first aspects.

[0024] The beneficial effects of the present invention are as follows: the present invention fixes the direction of the wire core to be inserted into the wire dialing mechanism by setting a wire adjusting mechanism between the wire feeding mechanism and the wire dialing mechanism, thereby facilitating the accuracy of the wire core when it is later inserted into the wire adjusting mechanism. Compared with the prior art, the four cables are respectively inserted into the chambers corresponding to the straight hole and the inclined hole through the setting of the cross-shaped first branching plate and the second branching plate, thereby improving the accuracy and reliability of the wire core.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] The wire insertion device shown in Figures 1 to 7, as shown in Figure 1, includes a wire dialing mechanism 1, a wire adjusting mechanism 2 and a wire feeding mechanism 3; wherein, as shown in Figure 2, the wire dialing mechanism 1 includes a base 11, straight holes 12 arranged in parallel on the base 11 in the transverse direction, an oblique hole 13 arranged in parallel with the straight hole 12 in the longitudinal direction, and a wedge plate 14 arranged between two adjacent straight holes 12 and the oblique hole 13; the wire dialing mechanism 1 here is the same as the structure of the prior art, and its function is to lift two of the four wire cores so as to facilitate the subsequent processing of two side-by-side wire cores at a time, such as the stripping operation of the wire core;

[0040] As shown in FIG3 , the line adjustment mechanism 2 is arranged opposite to the line dialing mechanism 1. The line adjustment mechanism 2 has a fixing frame 21, a threading barrel 22 arranged on the fixing frame 21, and a line dividing assembly 23 inserted into the threading barrel 22. The relative arrangement here means that the axial direction of the threading barrel 22 corresponds to the center position of the straight hole 12 and the oblique hole 13. The function of the line dividing assembly 23 is to separate the four wire cores so that each wire core corresponds to the straight hole 12 and the oblique hole 13 respectively.

[0041] The structure of the wire feeding mechanism 3 is shown in FIG1 . The wire feeding mechanism 3 is arranged toward the wire adjusting mechanism 2 and is used to clamp the wire bundle after core stripping and extend it into the wire threading barrel 22 of the wire adjusting mechanism 2 until the inner core of the wire bundle extends into the straight hole 12 and the oblique hole 13 of the wire dialing mechanism 1 respectively. The core stripping here refers to stripping the outer insulation of the wire bundle to expose the four inner cores. In the embodiment of the present invention, the four wire cores also have different colors to facilitate distinction during subsequent processing.

[0042] As shown in Figures 3 and 4, the inner diameter of the wire threading barrel 22 is flared toward the wire feeding mechanism 3, and the wire dividing assembly 23 includes a first wire dividing plate 23a and a second wire dividing plate 23b arranged in a cross-shaped manner. A horizontal wire dividing shovel 23a1 extends forward from the center of the end face of the first wire dividing plate 23a, and a longitudinal wire dividing shovel 23b1 intersecting with the horizontal wire dividing shovel 23a1 extends forward from the center of the end face of the second wire dividing plate 23b, and the length of the horizontal wire dividing shovel 23a1 is greater than the length of the longitudinal wire dividing shovel 23b1.

[0043] Through the above arrangement, when the wire bundle with the outer insulation layer stripped off is inserted into the wire barrel 22, as the bell mouth of the wire barrel 22 shrinks, the four wire cores gradually fit into the inner wall of the wire barrel 22, and then first contact the horizontal wire dividing shovel 23a1, and the four wire cores are divided into two layers, upper and lower. Then, as the four wire cores continue to be inserted, the four wire cores in the upper and lower layers all contact the longitudinal wire dividing shovel 23b1, thereby realizing the separation of the four wire bundles. As shown in Figure 4, each quadrant of the cross-shaped wire dividing assembly 23 has a wire bundle. Through such an arrangement, coupled with the restriction of the inner wall of the wire barrel 22, continuing to extend the wire bundle forward will cause the four wire bundles to enter the two straight holes 12 and the two oblique holes 13 respectively, thereby realizing the expansion of the angle between the wire core in the oblique hole 13 and the two wire cores in the straight hole 12. In the embodiment of the present invention, after the angle between the wire cores is expanded, the wire stripping assembly can be moved back and then the two layers of wire cores can be stripped or terminal crimped separately.

[0044] In the above embodiment, by setting up the line adjusting mechanism 2 between the line feeding mechanism 3 and the line dialing mechanism 1, the direction of the wire core to be inserted into the line dialing mechanism 1 is first fixed, thereby facilitating the accuracy of the wire core when it is later inserted into the line adjusting mechanism 2. Compared with the prior art, by setting up the cross-shaped first branching plate 23a and the second branching plate 23b, the four cables are respectively inserted into the chambers corresponding to the straight hole 12 and the inclined hole 13, thereby improving the accuracy and reliability of the wire core.

[0045] Based on the above embodiment, in this embodiment of the present invention, both sides of the first and second branching plates 23a, 23b have symmetrically arranged inclined surfaces. These inclined surfaces provide a certain degree of guidance for the wire cores after they are inserted into the threading barrel 22. Specifically, the inclined surfaces occupy increasingly larger axial spaces within the threading barrel 22, which allows for more reliable separation of the wire cores during insertion, until each wire core is fully within its corresponding quadrant.

[0046] In addition, in the embodiment of the present invention, the threading barrel 22 also has an adjustment function, specifically, the threading barrel 22 can be relatively rotatably arranged on the fixed frame 21. In this way, through the rotatable setting, when the wire core is tilted, the wire core contacts the above-mentioned inclined side when it is inserted. When the angle of the wire core does not correspond, the force of the contact between the wire core and the inclined side will drive the threading barrel 22 to adjust a certain angle, thereby allowing the wire core to enter each corresponding quadrant; of course, it should be pointed out here that, in the embodiment of the present invention, the inner diameter of the threading barrel 22 is set to be slightly larger than the outer diameter of the wire harness, so that each cavity separated by the branching assembly 23 in the threading barrel 22 can only enter one wire harness; through the above-mentioned adaptive adjustment, the occurrence of the wire harness being stuck in the threading barrel 22 is also avoided, thereby improving the success rate of threading.

[0047] In an embodiment of the present invention, in order to further improve the success rate of threading, an identification mechanism is provided on the basis of adaptive adjustment. Specifically, as shown in Figures 5 and 6, the first branch plate 23a and the second branch plate 23b are provided on the side facing the threading mechanism 1 and protrude from the threading drum 22, and a visual identification mechanism is fixed on the fixed frame 21 and provided with the protruding portion of the first branch plate 23a and the second branch plate 23b. It also includes a driving mechanism 4 for driving the threading drum 22 to rotate. In an embodiment of the present invention, an implementation structure of the driving mechanism 4 is shown in Figure 7. A driving wheel with a protruding arrangement is provided on the other side of the threading drum 22 away from the branch assembly 23. The threading drum 22 is driven to rotate by contact between an external driving wheel group and the driving wheel. Of course, it should be pointed out here that there are many ways to drive the threading drum 22 to rotate, such as a gear structure driven by a motor that directly meshes with the teeth provided on the threading drum 22, or a rack structure driven by a cylinder, etc. Visual identification can also be a method of determining the color and position of the cable by grayscale value in the prior art, which will not be described in detail here.

[0048] In some embodiments of the present invention, as shown in FIG4 , in order to further clearly distinguish the cable colors and their locations, the surfaces of the first and second branch boards 23a and 23b that are in contact with the cables are coated black, and the surfaces of the first and second branch boards 23a and 23b where the corners 231 are located are coated white; the specific identification method in the embodiments of the present invention is described in detail below, and those skilled in the art may refer to the following for understanding.

[0049] In an embodiment of the present invention, to prevent deformation of the wire harness after rotation, as shown in FIG1 , the wire feeding mechanism 3 includes a longitudinal drive assembly 31 disposed toward or away from the wire adjustment mechanism 2, and a rotation drive assembly 32 connected to the longitudinal drive assembly 31 and clamping the wire. The rotation drive assembly 32 rotates synchronously with the threading drum 22. The synchronous rotation of the rotation drive assembly 32 and the threading drum 22 maintains the shape of the wire harness, preventing any impact on subsequent processing.

[0050] In an embodiment of the present invention, a line plugging method using the above-mentioned line plugging device is also provided, as shown in FIG8 , comprising the following steps:

[0051] S10: Check whether the cable is in place; whether the cable is in place can be determined by identifying the position of the cable in the length direction;

[0052] S20: Identify whether the position of the cable complies with the set line sequence;

[0053] S30: If the set line sequence is met, the longitudinal drive assembly 31 is driven to continue moving so that the wire core enters the wire-pulling mechanism 1;

[0054] S40: If the threading sequence does not match the set sequence, the threading drum 22 is driven to rotate by the driving mechanism 4 until the set sequence is reached and then the longitudinal driving assembly 31 is driven.

[0055] As shown in Figure 9, when identifying whether the cable position conforms to the line sequence, the first step is to detect whether the corner 231 of the first branch plate 23a or the second branch plate 23b is in the center position. Then, the threading drum 22 is rotated according to the set line sequence number. The line sequence numbering method is to number the wire cores in the circumferential direction, and the rotation drive assembly 32 rotates synchronously with the threading drum 22. As shown in Figure 9, the first wire in the upper right corner is numbered 1, and the wires are numbered 1, 2, 3, and 4 in clockwise order. Of course, it should be pointed out here that those skilled in the art can also number counterclockwise or start from other positions. The numbers correspond to the colors of the wire cores, for example, 1 corresponds to cyan, 2 corresponds to blue, 3 corresponds to red, 4 corresponds to green, etc.

[0056] As shown in FIG10 , when the threading barrel 22 is rotated, the angle of rotation is θ=(expected number-actual number)*90°+α, where α=arcsin(A / R), where A is the distance between the center and the corner 231 near the center of the first branching plate 23a or the second branching plate 23b, and R is the outer diameter of the threading barrel 22. In an embodiment of the present invention, the rotation angle is identified by the corner 231 of the branching plate near the center, which can avoid the problem of difficulty in identifying the distance due to deformation of the wire core. As shown in FIG10 , after the distance A is identified, the angle at which the branching plate returns to its normal position is first calculated, and then n 90-degree conversions are performed.

[0057] In an embodiment of the present invention, there is also provided an automatic production line for the second half of an HSD, including the above-mentioned plug-in device. By improving the plug-in device, the reliability of the entire production line is improved, thereby improving the qualification rate of the entire production line. Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the invention to be protected.
