Description

Technical Field

[0001] The present invention relates to the technical field of data cable conductor processing, and specifically, it is a processing process and device for anti-electromagnetic interference high-speed data cable conductors. Background Art

[0002] An anti-electromagnetic interference high-speed data cable is a cable used for high-speed and stable data transmission between electronic devices. It resists external electromagnetic interference through designs such as a metal shielding layer, special insulating materials, and a reasonable stranding structure, has high-speed transmission capabilities, can meet the requirements of high-speed protocols such as USB, can significantly reduce the bit error rate, ensure accurate data transmission between various electronic systems of an aircraft in the aerospace field, and ensure the stable operation of each component in a complex electromagnetic environment in the automotive electronic system. It is widely used in multiple fields such as computers, communications, and industrial automation.

[0003] In the Chinese patent with the application number 202222009725X, specifically an equidistant cutting device for processing data cables of electronic devices, a tool control mechanism can drive a cutting tool to reciprocate up and down, enabling the cutting tool to cleanly perform the cutting action on the data cable. And when the cutting tool is in a disengaged state from the data cable, the tool control mechanism can drive a driving rotation through a transmission mechanism. Thus, the driving roller can perform the conveying action on the data cable. In this way, the device has a function of fixed-length conveying of the data cable, which can greatly improve the processing efficiency.

[0004] However, the above patent document does not tighten the data cable conductor and does not have the function of straightening both ends of the data cable. Since the straightening force cannot be applied to both ends of the data cable, the data cable is prone to bending and deformation, making it difficult for the cutting tool to perform cutting along an ideal straight trajectory, easily resulting in uneven cut edges and serious burr phenomena. Such uneven cut edges will cause problems in the adaptation of the data cable to the interface in the subsequent electronic device assembly process, increasing the complexity and cost of assembly, and greatly reducing the production efficiency and product qualification rate.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a processing process and device for anti-electromagnetic interference high-speed data cable conductors to solve the problems mentioned in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A processing process for anti-electromagnetic interference high-speed data cable conductors includes the following steps:

[0008] Step 1: Blank loading and clamping preparation: Place the data line conductor blank on the top of the guide frame 1 on the operating table board included in the feeding mechanism. One end of the data line conductor blank is pushed to the top of the guide frame 2 through the guide frame 1. The driving wheel rotates and drives the driving plate and the swing rod to deflect synchronously and reciprocally. The vertical moving long block drives the upper pressing frame to move downward, and the receiving frame presses against the data line conductor blank to ensure that the blank is taut and straight during cutting;

[0009] Step 2: Cutting operation: The motor drives the driving wheels at both ends of the rotating shaft to rotate circumferentially through the meshing connection of gear 1 and gear 2. The driving wheels rotate in the driving grooves opened in the middle of the driving plate, and further drive the driving plate and the swing rod connected to its outside to deflect synchronously and reciprocally. During the reciprocating deflection of the swing rod, through the cooperation with the vertical moving groove of the vertical moving long block, the vertical moving long block is further driven to move downward along the track rod until the receiving frame at the bottom of the upper pressing frame presses tightly against the top of the data line conductor blank;

[0010] The upper pressing frames below the two sliding sleeves located outside the same horizontal guide rod respectively press tightly against the top of the same data line conductor blank on the top of the guide frame 1 and the guide frame 2. Under the action of the spring group, the receiving frames at the top and bottom of the data line conductor blank press tightly against it effectively. When the driving wheel rotates again, at this time, the two sliding sleeves located outside the same horizontal guide rod move away from each other, and the upper pressing frame cooperates with the receiving frames in the guide frame 1 and the guide frame 2, and then straightens the data line conductor blank in two opposite directions from the cutting position, ensuring that the cutting part of the data line conductor blank is always in a taut and straight state. Subsequently, the electric push rod drives the cutter to accurately cut the blank;

[0011] Step 3: Semi-finished product removal and new blank in place: The driving wheel rotates to make the upper pressing frame move upward and loosen. The electric gripper moves horizontally and clamps the data line conductor semi-finished product and removes it. The new data line conductor blank is pushed from the guide frame 1 to the guide 2, and the upper pressing frame presses tightly and straightens again to prepare for the next cutting.

[0012] Furthermore, an anti-electromagnetic interference high-speed data line conductor processing device includes an operating table board. The feeding mechanism includes the operating table board. The top of the operating table board is symmetrically and fixedly installed with frames. Two horizontal guide rods are fixedly connected between the two frames. The top of the operating table board and symmetrically and fixedly installed with two support frames between the two frames;

[0013] The outside of the horizontal guide rod is slidably connected with a sliding sleeve in a sleeved manner. The bottom of the sliding sleeve is fixedly connected with a translation long block. The side wall of the translation long block is fixedly installed with a track rod with an I-shaped cross-section. The outside of the track rod is slidably connected with a lifting block, and the side wall of the lifting block is fixedly connected with a vertical moving long block. The bottom of the vertical moving long block is fixedly connected with a mounting frame, and one side of the bottom of the mounting frame is fixedly installed with an upper pressing frame.

[0014] Further, a rotating shaft is movably connected inside the support frame through bearings, and driving wheels are fixedly connected to both ends of the rotating shaft outside the support frame. Driving plates are movably connected to both side walls of the support frame through bearings, and driving grooves for the driving wheels to rotate are formed in the middle of the driving plates.

[0015] Further, a swinging rod is fixedly connected to the side wall of the driving plate, a linkage block is fixedly connected to the side wall of the driving wheel, a translation groove for the linkage block to move is formed in the side wall of the translation long block, and a vertical translation groove for the swinging rod to move is formed in the side wall of the vertical translation long block.

[0016] Further, a first material guiding frame and a second material guiding frame are fixedly installed on the top of the operating table board, and receiving frames are arranged inside the upper pressing frame, the first material guiding frame, and the second material guiding frame.

[0017] Further, a slide rail is fixedly installed at a position on the top of the operating table board close to the tail end of the second material guiding frame. A sliding seat is slidably connected inside the slide rail, and a threaded rod matched with the sliding seat is movably connected inside the slide rail;

[0018] An electric claw is fixedly installed on the top of the sliding seat through an equipment rack.

[0019] Further, support frames are fixedly connected to both sides of the two transverse guide rods on the top of the operating table board. A cutting knife is arranged at the bottom of the support frame, and an electric push rod for driving the cutting knife to move is fixedly installed on the top of the support frame.

[0020] Further, a first gear is sleeved and fixed on the outside of the rotating shaft inside the support frame. A housing is fixedly installed on the side wall of the support frame. A second gear meshing with the first gear is movably connected inside the housing through a bearing, and a motor for driving the second gear to rotate is fixedly installed outside the housing.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In the present invention, the two upper pressing frames on the outside of the same transverse guide rod move in opposite directions along a preset rectangular trajectory. This movement mode enables the upper pressing frames to cooperate with the first material guiding frame and the second material guiding frame to apply force evenly from both sides of the cutting position of the data line conductor and move in opposite directions, realizing the straightening and anti-deviation correction of the data line conductor, overcoming problems such as the bending of the data line and uneven force caused by the inability to straighten in traditional cutting equipment, effectively avoiding the offset phenomenon caused by the elasticity or uneven stress distribution of the material itself during the cutting process, ensuring that the cutting position is always in an ideal straight line state. Since the data line conductor is accurately straightened and stably fixed before cutting, the cut of the cutting knife on the data line conductor is always flat and smooth, greatly reducing the generation of burrs.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: As Figures 1-9As shown in the figure, a processing device for an anti-electromagnetic interference high-speed data line conductor, the feeding mechanism includes an operating table board 1. On the top of the operating table board 1, racks 2 are symmetrically and fixedly installed. Between the two racks 2, two horizontal guide rods 3 are fixedly connected. By setting two horizontal guide rods 3, the number of data line conductors cut at one time is further increased;

[0036] Combined with Figure 3 the horizontal guide rod 3 in [reference], in the present invention, to improve the stability of the sliding sleeve 5 sliding horizontally back and forth on the outside of the horizontal guide rod 3, the two side walls of the horizontal guide rod 3 are set as vertical planes, so as to ensure that the sliding sleeve 5 does not deflect during the process of sliding back and forth on the outside of the horizontal guide rod 3. On the top of the operating table board 1 and symmetrically fixed between the two racks 2, two support frames 8 are installed;

[0037] The outside of the horizontal guide rod 3 is slidably connected with a sliding sleeve 5 in a sleeved manner. The bottom of the sliding sleeve 5 is fixedly connected with a translation long block 10. On the side wall of the translation long block 10, a track rod 11 with an I-shaped cross-section is fixedly installed. The outside of the track rod 11 is slidably connected with a lifting block, and the side wall of the lifting block is fixedly connected with a vertical translation long block 12. The bottom of the vertical translation long block 12 is fixedly connected with a mounting frame, and on one side of the bottom of the mounting frame, an upper pressing frame 13 is fixedly installed.

[0038] Inside the support frame 8, a rotating shaft 100 is rotatably connected through a bearing. At both ends of the rotating shaft 100 located outside the support frame 8, driving wheels 7 are fixedly connected. On both side walls of the support frame 8, driving plates 6 are rotatably connected through bearings. In the middle of the driving plate 6, a driving groove for the driving wheel 7 to rotate is opened. Outside the rotating shaft 100 located inside the support frame 8, a first gear is sleeved and fixed;

[0039] On the side wall of the support frame 8, a housing 200 is fixedly installed. Inside the housing 200, a second gear meshing with the first gear is rotatably connected through a bearing. And on the outside of the housing 200, a motor for driving the second gear to rotate is fixedly installed. Combined with Figure 3 and Figure 8 shown in the figure, the motor drives the second gear to drive the first gear and the rotating shaft 100 to rotate synchronously, and further drives the driving wheels 7 at both ends of the rotating shaft 100 to rotate, so that the driving wheels 7 on both sides of the support frame 8 rotate synchronously.

[0040] On the side wall of the driving plate 6, a swinging rod 9 is fixedly connected. On the side wall of the driving wheel 7, a linkage block 14 is fixedly connected. On the side wall of the translation long block 10, a translation groove for the movement of the linkage block 14 is opened. On the side wall of the vertical translation long block 12, a vertical translation groove for the movement of the swinging rod 9 is opened.

[0041] A feeding guide frame 151 and a feeding guide frame 152 are fixedly installed on the top of the operation table board 1. Receiving frames are arranged inside the upper pressing frame 13, the feeding guide frame 151 and the feeding guide frame 152, and the receiving frames are connected to the upper pressing frame 13, the feeding guide frame 151 and the feeding guide frame 152 through multiple groups of springs. Specifically, the receiving frames located inside the feeding guide frame 151 and the feeding guide frame 152 are in a sliding connection state relative to the feeding guide frame 151 and the feeding guide frame 152, and the two are connected by springs, so that the receiving frames can slide horizontally in the feeding guide frame 151 and the feeding guide frame 152 for a certain distance and then automatically reset under the action of the springs;

[0042] The receiving frame located inside the upper pressing frame 13 can only move a certain distance in the vertical direction and automatically reset under the action of the corresponding spring. The receiving frame inside the upper pressing frame 13 cooperates with the receiving frames inside the feeding guide frame 151 and the feeding guide frame 152, and then will clamp data line conductors with different diameters. Combining Figure 2 and Figure 7 As shown, the receiving frame inside the feeding guide frame 151 is used to place the data line conductor blanks after the cable coils are straightened, and the receiving frame inside the feeding guide frame 152 is used to place the semi-finished data line conductors after cutting.

[0043] Embodiment 2: A slide rail 16 is fixedly installed at the top of the operation table board 1 and near the tail end of the feeding guide frame 152. A sliding seat 17 is slidably connected inside the slide rail 16. A threaded rod cooperating with the sliding seat 17 is movably connected inside the slide rail 16. An electric gripper 18 is fixedly installed at the top of the sliding seat 17 through an equipment rack. As Figure 2 shown, a servo motor for driving the threaded rod to rotate is fixedly installed outside the slide rail 16, and the electric gripper 18 is an existing device for clamping the semi-finished data line conductors to move and drag the data line conductor blanks;

[0044] Support frames 19 are fixedly connected to both sides of the two transverse guide rods 3 at the top of the operation table board 1. A cutting knife 20 is arranged at the bottom of the support frame 19. An electric push rod for driving the cutting knife 20 to move is fixedly installed at the top of the support frame 19. The electric push rod drives the cutting knife 20 to descend and perform fixed-length cutting on the data line conductors.

[0045] Combining Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows:

[0046] After the cable coil is straightened, it is placed in the receiving frame on the top of the guide frame 151 on the top of the operating table 1 included in the unwinding mechanism, and one end of the data line conductor embryo is placed in the receiving frame on the top of the guide frame 152. The motor drives the driving wheels 7 at both ends of the rotating shaft 100 to rotate in a circle through the meshing connection of the gear 1 and the gear 2. The driving wheel 7 rotates in the driving groove opened in the middle of the driving plate 6, and further drives the driving plate 6 and the swing rod 9 connected to the outside thereof to perform synchronous reciprocating deflection. During the reciprocating deflection, the swing rod 9 cooperates with the vertical moving groove of the vertical moving length block 12, and further drives the vertical moving length block 12 to move downward along the track rod 11, until the receiving frame at the bottom of the upper pressing frame 13 is pressed against the top of the data line conductor embryo;

[0047] Depend on Figure 3 as well as Figure 9 It is thought that the upper pressing frame 13 below the two sliding sleeves 5 located outside the same transverse guide rod 3 is respectively pressed against the top of the same data line conductor embryo body at the top of the material guide frame 1 151 and the material guide frame 2 152, and under the action of the spring group, the material receiving frames located at the top and bottom of the data line conductor embryo body are effectively pressed against it. When the driving wheel 7 rotates again, the two sliding sleeves 5 located outside the same transverse guide rod 3 are away from each other, and the upper pressing frame 13 cooperates with the material guide frame 1 151 and the material receiving frames in the material guide frame 2 152, thereby straightening the data line conductor embryo body from the cutting position to two opposite directions, ensuring that the cutting position of the data line conductor embryo body is always in a tight and straight state, and then the electric push rod drives the cutter 20 to move downward and accurately cut the data line conductor embryo body;

[0048] When the data line conductor embryo is cut, the two upper pressing frames 13 are respectively pressed against the top of the data line conductor embryo and the data line conductor semi-finished product. At this time, the driving wheel 7 rotates again, and the two upper pressing frames 13 move vertically upward under the cooperation of the driving plate 6, the vertical moving block 12 and the swing rod 9, further contacting and pressing the data line conductor embryo and the data line conductor semi-finished product. Then the servo motor drives the threaded rod to rotate and further drives the sliding seat 17 to drive the electric clamp 18 to move horizontally along the slide rail 16. After approaching the data line conductor semi-finished product, the electric clamp 18 is used to clamp the end away from the cutting position. Then the sliding seat 17 moves in the opposite direction and drives the data line conductor semi-finished product to move out from above the material guide frame 2 152. Then the data line conductor embryo that has not been cut is pushed into the material guide frame 2 152 again through the material guide frame 1 151. Then the upper pressing frame 13 moving along the rectangular trajectory is used to press and straighten the data line conductor embryo again, and finally reciprocating cutting is performed.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments only. Obviously, many modifications and variations can be made according to the content of this specification.
