Description

Technical Field

[0001] This application relates to the field of high-speed cable manufacturing technology, specifically to size-compensated crimping terminal equipment. Background Technology

[0002] With the rapid development of 5G communication, cloud computing, and big data centers, the demand for high-speed cables (such as SFP, QSFP, DAC, etc.) has increased dramatically. In the production process of high-speed cables, terminal crimping is a core process that determines signal integrity (SI) and the reliability of mechanical connections.

[0003] Currently, automated riveting processes typically employ the following steps: First, one end of the wire is pre-treated by removing aluminum foil and stripping insulation. Then, a straight wire is transported to the riveting station via a fixture. A bending mechanism bends the wire upwards, and finally, it is pushed into the terminal in the terminal flow channel for riveting.

[0004] However, in actual production, this solution has the following significant drawbacks:

[0005] Although pretreatment can ensure that the initial length of the wires extending from the fixture is basically consistent, the wires undergo plastic deformation during upward bending. Due to the differences in the hardness and elastic modulus of the wire material itself, as well as the influence of ambient temperature, the amount of springback of each wire is not the same, resulting in random deviations in the effective projected length after bending. At the same time, the tilting and pushing action is easily affected by frictional resistance and the stiffness of the wire itself, producing slight "head-up" or "head-down" phenomena, making it impossible to achieve high-precision consistency in the depth and radial position of the wire end entering the terminal.

[0006] Existing equipment mostly relies on vision systems to adjust the position of the riveting head to "accommodate" the displacement deviation of the wire. This "passive compensation" has extremely high requirements for the accuracy of light and sensors, and cannot fundamentally eliminate the geometric distortion of the wire itself, making it difficult to guarantee the impedance consistency of high-frequency signals.

[0020] Compared with the prior art, the beneficial effects of this application are:

[0022] 2) This application is equipped with a bending forward shaping unit, which moves the bending fulcrum from the edge of the fixture to the contact point of the precision roller through the roller body, and cooperates with the translational rolling shaping of the roller body to make the bending area undergo controlled plastic flow, reshaping the unstable natural bend into a uniform geometric shape; this design transforms the "bending point" into a physical reference defined by precision machinery, locking the effective working length of the wire.

[0023] 3) This application not only retains the visual monitoring compensation function of the riveting CCD, but also combines physical straightening and shaping treatment; this "rigid and flexible" solution has strong anti-interference ability and higher stability in complex industrial environments, which can ensure the extreme accuracy of the riveting position of high-speed cables, and is particularly suitable for the production of high-speed cables with extremely fine wire diameters.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] Example:

[0045] Please see Figures 1 to 17 This application provides a technical solution: a size-compensated riveting terminal device, including a Y-axis moving part 1, a terminal conveying channel 2 and a feeding part 3 located at the upper end of the Y-axis moving part 1 (the material strip is wound on the feeding part 3, and the feeding part 3 is used to feed the material strip), a solder paste spraying unit 4 and a riveting unit 5 disposed on the moving end of the Y-axis moving part 1, a material strip conveying part 7 disposed on the moving end of the Y-axis moving part 1, and a wire bending unit 6 located below the riveting unit 5; when the moving end of the Y-axis moving part 1 moves, it can drive the solder paste spraying unit 4, the riveting unit 5, and the material strip conveying part 7 to move synchronously, and the overall position of the above three components can be adjusted synchronously.

[0046] The material conveying unit 7 includes a motor 71 fixed to the moving end of the X-axis moving part 51, a feeding wheel 72 fixed to the electrode output shaft, and a feeding flange 73 integrally formed on the outer ring wall of the feeding wheel 72 for entering the through hole of the material strip. The feeding flange 73 can match the positioning through hole opened on the material strip in the terminal conveying channel 2. The feeding flange 73 can enter the positioning through hole. When the motor 71 drives the feeding wheel 72 to rotate, the rotation of the feeding wheel 72 can drive the material strip in the terminal conveying channel 2 to move through the feeding flange 73. The movement of the material strip drives the terminals connected to the material strip to move synchronously, so that the terminals can move to the position of the solder paste spraying unit 4 and the riveting unit 5.

[0047] like Figure 1 and Figure 2As shown, the solder paste application unit 4 includes an X-axis moving part 41 fixed to the moving end of the Y-axis moving part 1, a Y-axis moving part 42 fixed to the moving end of the X-axis moving part 41, a Z-axis moving part 43 fixed to the moving end of the Y-axis moving part 42, a soldering CCD 44 fixed to the moving end of the Z-axis moving part 43, and a soldering part 45 fixed to the moving end of the Z-axis moving part 43. The operation of the X-axis moving part 41 can drive the Y-axis moving part 42, the Z-axis moving part 43, the soldering CCD 44, and the soldering part 45 to move synchronously back and forth, thereby adjusting the position of the soldering part 45 and the soldering CCD 44, allowing the soldering part 45 to move to the terminal. The terminal is placed above the inner wall of the terminal or above the straight wire end in the fixture within the conveyor channel 2, and soldering is performed on the inner wall of the terminal and the upper surface of the wire end. The soldering CCD 44 can perform visual inspection of the soldering area. The moving end of the Y-axis moving part 2 42 can drive the Z-axis moving part 1 43, the soldering CCD 44, and the soldering part 45 to move horizontally left and right synchronously, adjusting the Y-axis position of the Z-axis moving part 1 43, the soldering CCD 44, and the soldering part 45. The moving end of the Z-axis moving part 1 43 can drive the soldering CCD 44 and the soldering part 45 to rise or fall synchronously, adjusting the Z-axis height of the soldering CCD 44 and the soldering part 45.

[0048] like Figures 1-3 As shown, the riveting unit 5 includes an X-axis moving part 2 51 fixed to the moving end of the Y-axis moving part 1, an X-axis moving part 3 52 fixed to the moving end of the X-axis moving part 2 51, and a frame 53 fixed to the moving end of the X-axis moving part 3 52. A riveting part 54 and a riveting CCD 55 are provided on one side of the frame 53. A wire positioning part 56, a wire pressing unit 57, and a waste cutting cylinder 8 are also connected to the moving end of the X-axis moving part 2 51. Controlling the operation of the X-axis moving part 2 51 can drive the X-axis moving part 3 52, the frame 53, the riveting part 54, and the wire positioning part 56. The positioning unit 56, wire pressing unit 57, riveting CCD 55, and waste cutting cylinder 8 move back and forth as a whole. The purpose is to move the entire riveting unit 5 to avoid being in a different position. The operation of the X-axis moving part 3 52 can drive the frame 53, riveting part 54, and riveting CCD 55 to move slightly back and forth. The riveting CCD 55 is a size-compensated vision camera used to visually capture the size of the copper foil opening of the wire and the position of the terminal and the wire. When the terminal position moves slightly, the position of the riveting part 54 can be adjusted by the X-axis moving part 3 52 to adjust the riveting position and realize the function of the terminal following the riveting.

[0049] The telescopic end of the waste cutting cylinder 8 is fixed with a cutting blade for cutting the waste on the terminal conveying channel 2. When the material strip moves to the right and passes through the riveting unit 5, the terminals on the material strip have been riveted to one end of the wire. Therefore, the terminals on the material strip have been removed from the material strip. At this time, the material strip is waste. The waste strip will move to the bottom of the waste cutting cylinder 8. At this time, the waste cutting cylinder 8 is controlled to extend and drive the cutting blade to descend, and the cutting blade completes the cutting process of the waste strip.

[0050] like Figure 3 and Figure 4 As shown, the wire bending unit 6 includes a cylinder 3 61 fixedly connected to one side of the terminal conveying channel 2, a second slider 62 slidably connected to the outside of the cylinder 3 61 and fixedly connected to the telescopic end of the cylinder 3 61, and a bending blade 63 fixedly connected to the upper end of the second slider 62. The cylinder 3 61 is used to drive the bending blade 63 to rise and contact the wire and bend the wire. The cylinder 3 61 is located between the cylinder 4 91 and the cylinder 5 101.

[0051] When cylinder 61 extends, it can drive the second slider 62 to move upward. The upward movement of the second slider 62 can drive the bending knife 63 to move upward. The upper end of the bending knife 63 can contact one end of the wire on the fixture.

[0052] The wire bending unit 6 has two functions: 1. Before the wire is riveted to the terminal, one end of the wire after being soldered by the solder paste spraying unit 4 is straight (e.g., ...). Figure 10 As shown), when the straight end of the wire moves above cylinder 61 along with the fixture, the bending blade 63 rises and contacts one end of the wire, pushing the wire upward to bend it, thus changing the wire from a straight state to a bent state (as shown). Figure 17 As shown in the diagram, this facilitates the wire pressing unit 57 in pushing the bent wire into the wire groove 22, at which point the wire will change from a bent state back to a relatively straight state. Figure 17 The first part shows the straight and bent states of the wire. 2. When the wire is located in the wire groove 22 and one end of the wire is riveted to the terminal, the bending knife 63 rises and contacts the wire to push the wire upward, so that the riveted end of the wire can be moved out of the wire groove 22. At the same time, the terminal riveted to one end of the wire will separate from the material strip.

[0053] like Figure 3 and Figure 5As shown, the wire pressing unit 57 includes a second cylinder 571 fixed to one side of the frame 53, a first slide rail 572, a second slide block 573 slidably connected to the first slide rail 572 and fixed to the second cylinder 571 on one side, and a pressing knife 574 fixed to one side of the second slide block 573. Before the wire is riveted to the terminal, one end of the wire after being soldered by the solder paste spraying unit is straight. When the straight end of the wire moves above the third cylinder 61 with the fixture, it is bent by the bending knife. The 63 rises and contacts one end of the wire, pushing the wire to bend upwards, changing the wire from a straight state to a bent state. This makes it easier for the wire pressing unit 57 to push the bent wire into the wire groove 22. The specific operation of the wire pressing unit 57 is as follows: the cylinder 2 571 works to drive the second slide 573 to slide along the slide rail 1 572. The pressing knife 574 on one side of the second slide 573 will contact the upwardly bent end of the wire and press the bent end of the wire into the wire groove 22.

[0054] like Figure 9 As shown, a translation adjustment section 21 is provided on one side of the terminal conveying channel 2, and the translation adjustment section 21 is fixedly connected to the moving end of the X-axis moving part 51. A positioning block 25 is fixed on the terminal conveying channel 2, and the positioning block 25 is provided with a wire groove 22 and a slot 24 that is connected to the wire groove 22 and can accommodate the flattening knife 564. Two guide holes 23 for accommodating the guide post 565 are also symmetrically opened inside the positioning block 25.

[0055] The translation adjustment section 21 is an independent terminal conveying channel 2 that can move along with the moving end of the X-axis moving part 2 51. When the moving end of the X-axis moving part 2 51 drives the X-axis moving part 3 52, the frame 53, the riveting part 54, the wire positioning part 56, the wire pressing unit 57, the riveting CCD 55, and the waste cutting cylinder 8 to move back and forth as a whole, the translation adjustment section 21 can move synchronously with the above-mentioned unit components. The terminals in the translation adjustment section 21 will also move back and forth accordingly, thereby adjusting the position of the terminals. The wire groove 1 22 is used to accommodate the wire, the slot 24 is used to accommodate the flattening knife 564 and serves as a guide, and the guide hole 23 also serves as a guide.

[0056] like Figure 3 and Figure 8 As shown, the wire positioning part 56 includes a cylinder 561 fixedly connected to the moving end of the X-axis moving part 51, a first slider 562 slidably connected to the outside of the cylinder 561 and fixedly connected to the telescopic end of the cylinder 561, a pressure plate 563 fixedly connected to one side of the first slider 562, a flattening knife 564 fixedly connected to the lower end of the pressure plate 563, and two guide posts 565 symmetrically arranged on both sides of the flattening knife 564.

[0057] After the wire is pressed into the wire groove 22 by the pressing knife 574, the control cylinder 561 works and drives the first slider 562 to descend. The descent of the first slider 562 drives the pressure plate 563 and the flattening knife 564 to move downward, so that the flattening knife 564 can be inserted into the slot 24 and perform positioning processing on the wire in the wire groove 22, so that one end of the wire is positioned in the wire groove 22. At the same time as the first slider 562 descends, the two guide posts 565 can be inserted into the two guide holes 23 to achieve auxiliary alignment.

[0058] like Figure 3 , Figure 6 , Figure 8 As shown, the riveting part 54 includes a Z-axis moving part 541 fixed to one side of the frame 53, a first slide block 542 fixed to the moving end of the Z-axis moving part 541, and a riveting knife 543 fixed to one side of the first slide block 542; a sliding groove 544 is provided on one side of the riveting knife 543, and a guide flange extending into the sliding groove 544 is integrally formed on one side of the pressure plate 563;

[0059] By adopting the above scheme, when the wire is pressed into the wire groove 22 and flattened by the flattening knife 564, one end of the wire enters the material strip terminal. At this time, the control Z-axis moving part 541 works and drives the first slide 542 to move downward. The downward movement of the first slide 542 can drive the first slide 542 and the riveting knife 543 to move downward. At this time, the riveting knife 543 can descend and rivet the terminal, causing the metal of the terminal to undergo plastic deformation, tightly wrapping and biting one end of the wire body, thus completing the riveting. When the guide flange on one side of the pressure plate 563 enters the slide groove 544, during the descent of the riveting knife 543, the riveting knife 543 can descend along the guide flange on the pressure plate 563 through the slide groove 544. The slide groove 544 and the guide flange on the pressure plate 563 cooperate to play a guiding role.

[0060] Please see Figure 3 , Figure 10 and Figure 11 It also includes an error processing component 9 located below the terminal conveying channel 2, and the error processing component 9 includes a cylinder 4 91 fixed on the moving end of the Y-axis moving part 1, a third slider 92 slidably connected to one side of the cylinder 4 91 and fixedly connected to the telescopic end of the cylinder 4 91, a slide rail 2 93 fixedly connected to the upper end of the third slider 92, a third slide block 94 slidably connected to the slide rail 2 93, a drive component 1 connected to the upper end of the third slider 92 for driving the third slide block 94 to move back and forth, a fourth slide block 99 slidably connected to the upper end of the third slide block 94, a drive component 2 connected to the upper end of the third slide block 94 for driving the fourth slide block 99 to move left and right, a support frame 991 fixedly connected to the upper end of the fourth slide block 99, and a gripper 992 fixedly connected to the upper end of the support frame 991.

[0061] The clamp 992 holds the wire and moves one end of the wire toward the terminal to restore the straightness and length of the wire and compensate for the length of the wire after it is bent from the end of the fixture.

[0062] The first drive assembly includes a lead screw 96 rotatably connected to the upper end of the third slider 92 and a second motor 95 fixedly connected to the upper end of the third slider 92 with its output shaft connected to the lead screw 96; the second drive assembly includes a lead screw 97 rotatably connected to the upper end of the third slide block 94 and a third motor 98 fixedly connected to the upper end of the third slide block 94 with its output shaft connected to the lead screw 97.

[0063] The end of the wire extending from the fixture undergoes pre-treatment before riveting. Pre-treatment includes multiple processes such as removing aluminum foil, removing insulation, and cutting and shaping. After pre-treatment, the length of the wire extending from the fixture is basically the same, and the lengths of multiple wires in a single fixture will not differ significantly or vary in length. However, because the parallel wires need to be bent by bending blade 63, the upward bending of the wire is a plastic deformation process. Even if each wire extends from the fixture at the same length, after bending (wire bending unit 6 sequentially bends each wire...) The upward bending process, due to slight differences in the stiffness and elasticity of the wires, makes it difficult to guarantee an absolutely consistent bending angle, resulting in deviations in the position of the wire ends. The pushing process (where the inclined wire pressing unit 57 pushes the wire into the wire groove, the pushing force, angle, and friction conditions may vary slightly, causing slight fluctuations in the initial position of the wire in the wire groove) also results in variations in the relative positions of each wire and terminal. These errors accumulate, ultimately affecting the depth and radial position of the wire ends entering the terminal, causing variations in the relative positions of each wire. The relative position of the wire and the terminal is not completely consistent; therefore, when the wire pressing unit 57 pushes the wire into the wire groove, the control cylinder 4 91 works to drive the third slider 92 to rise, and at the same time, the gripper 992 also rises. Through the operation of motor 2 95 and motor 3 98, the lead screw 1 96 and lead screw 2 97 can be driven to rotate respectively, thereby driving the gripper 992 to move back and forth and left and right, adjusting the position of the gripper 992 so that the gripper 992 can move to the vicinity of the wire and place the wire between the two grippers of the gripper 992. 2. The wire is clamped (a pressure sensor is integrated inside the jaws of the clamp to detect the clamping force and avoid damage to the wire). After clamping, the clamp 992 is driven to move forward (towards the positioning block 25) to slightly straighten the wire. At the same time, a force sensor is set at the connection between the clamp 992 and the support frame 991 to detect the tension of the wire and avoid the tension exceeding the protection value and causing damage to the wire. When the wire is bent upward for the first time, it will rebound to a certain extent due to the elasticity of the material, and the amount of rebound of each wire is not completely consistent. By slightly straightening the wire, this springback can be actively overcome and calibrated, ensuring that the section of the wire from the bend point to the end is straight and points in the same direction, providing a basis for subsequent precise positioning. Furthermore, when the wire is pushed into the slot at an angle, its end may "raise" or "lower" due to friction with the slot wall or its own bending. The straightening action forces the end of the wire to extend along a preset, stable direction (usually the direction that best matches the direction of the terminal opening), allowing the wire to "penetrate" into the designated position inside the terminal at a more consistent angle and depth.

[0064] Compared to adjusting the terminal or riveting position, this wire pretreatment straightening method proactively corrects the wire to the standard position before critical steps, reducing errors at the source. This reduces the total amount of errors the system needs to handle, lowering the pressure and complexity of the compensation system. It also corrects the wire's own posture errors. Meanwhile, the terminal or riveting position adjustment method relies heavily on high-precision sensors and visual or force detection, making it sensitive to sensor contamination, light changes, and wire color / reflection. This wire pretreatment method has stronger anti-interference capabilities and is more stable and reliable in industrial environments. This application also incorporates two error compensation methods: controlling the bending variables of the wire and compensating for and adjusting the riveting position. When used together, these two methods can effectively improve the accuracy of the riveting position, making it particularly suitable for high-precision, high-speed automated wire riveting production lines.

[0065] Please see Figure 3 , Figure 10 , Figures 12-16 It also includes a bending forward shaping unit 10 located below the terminal conveying channel 2, and the bending forward shaping unit 10 includes a cylinder 101 fixed to the moving end of the Y-axis moving part 1, a fourth slider 102 slidably connected to one side of the cylinder 101 and fixed to the telescopic end of the cylinder 101, a lifting plate 103 fixed to the upper end of the fourth slider 102, and a shaping component 11 slidably connected to the upper end of the lifting plate 103; the shaping component 11 includes a follower seat 111 slidably connected to the upper end of the lifting plate 103, a cover plate 112 rotatably connected to one side of the follower seat 111, a hydraulic rod 113 with its mounting end rotatably connected to one side of the follower seat 111 and its telescopic end rotatably connected to one side of the cover plate 112, a clearance groove 114 opened inside the follower seat 111 for accommodating a clamp, and a wire groove 115 opened on the upper end of the follower seat 111 for accommodating wire.

[0066] The shaping component 11 also includes a movable seat 116 slidably connected in the second groove 115, two extended sliders 118 integrally formed on both sides of the movable seat 116 and slidably connected in the second groove 115, a groove 119 formed at the upper end of the two extended sliders 118, a movable groove 12 formed at the lower end of the cover plate 112, a movable seat 121 slidably connected in the movable groove 12, and a traction flange 122 integrally formed at the lower end of the movable seat 121 for insertion into the groove 119. Movable groove 123 is provided at the upper end of movable seat 116 and the lower end of movable seat 2 121. Roller 117 and roller 2 124 are rotatably connected in the two movable grooves 123 respectively. Movable groove 3 125 is provided at the upper end of cover plate 112. Limiting flange 126 is slidably connected in movable groove 3 125 and fixed to the upper end of movable seat 2 121. Electric push rod 127 is fixed inside cover plate 112, and the telescopic end of electric push rod 127 is fixed to one side of movable seat 2 121.

[0067] By adopting the above scheme, before the fixture is bent by the bending knife 63, after the fixture moves to the designated position above the cylinder 101 (achieved by sensor monitoring), the cylinder 101 extends and drives the lifting plate 103 to rise. At this time, the cover plate 112 is open, and the lower side of one end of the fixture can enter the clearance groove 114. The parallel wire extending from one end of the fixture can enter the wire groove 115. The hydraulic rod 113 is controlled to extend and push the cover plate 112 to flip on the follower seat 111 and cover the follower seat 111. At the same time, the traction flange 122 can be inserted into the groove 119. At this point, the outer surface of the wire in the second groove 115 is in contact with the first roller 117 and the second roller 124. The fixture continues to move towards the next process (wire bending unit 6). At this time, the follower seat 111 will slide on the lifting plate 103 along with the fixture. When the bending knife 63 bends one end of the wire, the R-angle position of the wire changes from contact with the fixture to contact with the second roller 124, realizing the forward movement of the R-angle position at the bending point of the wire. When the bending forward shaping unit 10 straightens the wire, it controls the electric push rod 127 above the straightened wire. The working arm extends and pushes the second movable seat 121 towards the positioning block 25. The movement of the second movable seat 121 drives the extension slider 118 and the first movable seat 116 to move via the traction flange 122. The movement of the first movable seat 116 and the second movable seat 121, through the roller body 117 and the second roller body 124, performs roll forming on the wire. The translational extrusion of the rollers causes further controlled micro-plastic flow of the metal in the R-angle region, thereby reshaping a variable and unstable natural bending shape into a uniform, stable, and design-compliant bending shape, eliminating bending springback. The two roller bodies... During the translational rolling process, the precise location of this "bending point" is actually defined and locked together. This point is transformed from a process product into a physical reference actively manufactured and confirmed by precision machinery (roller trajectory), which can compress the positional error of the wire entering the terminal to a very small range. At the same time, the initial bending will generate uneven residual stress inside and outside the R angle. The rolling process is equivalent to a gentle "straightening" or "forming" process, which can equalize these stresses and prevent the wire from undergoing slight deformation due to stress release during subsequent processing or use, thus affecting long-term reliability.

[0068] Error processing component 9 determines the direction of the straight segment at the end of the wire, similar to tightening a rope and determining the direction of the rope; bending forward shaping unit 10 determines the precise position of the wire bending reference point, similar to tying a fixed knot on the rope and determining the starting point of the effective length; when the two actions are completed in coordination, they jointly define the effective working length of a section of wire, that is, the section from the fixed bending point (reference point) of roll forming to the end of the wire; the length and direction of this section of wire are standardized at the same time, providing near-perfect geometric consistency for subsequent insertion of terminals, which is the physical basis for achieving ultra-high precision riveting.
