Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to a copper ring riveting mechanism for terminal wires. Background Technology

[0002] With the widespread adoption of communication cables that are standard in the AI ​​industry, there is a significant demand for Slingshot 224G DP terminal wires in AI servers. These terminal wires require copper rings to be crimped onto the exposed conductors after the insulation has been removed. Current copper ring crimping processes are typically performed in a step-by-step sequence: first, a wire feeding mechanism transports the cut and stripped terminal wires to the crimping station and positions them; then, a separate feeding system delivers the copper rings and places them in the designated position on the crimping die; finally, the crimping head presses down, firmly crimping the copper rings onto the exposed conductors of the terminal wires. This crimping method results in a complex equipment layout, large space requirements, and the need for two complete feeding systems. It also demands high synchronization accuracy, increasing the failure rate and debugging difficulty. The two independent feeding actions need to be precisely synchronized in time; any material jamming, supply failure, or positional deviation in either system will cause the other system to wait or the entire process to be interrupted, potentially leading to jamming, equipment collisions, and other malfunctions. This complicates equipment stability control and increases the difficulty of debugging and maintenance. Summary of the Invention

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figures 1-18 This embodiment provides a copper ring riveting mechanism for terminal wires, including a lower riveting knife holder 10. An upper riveting knife holder 12 is provided on the lower riveting knife holder 10 via two columns 11. The upper riveting knife holder 12 can move up and down along the columns to realize the riveting action. A first buffer spring 13 is sleeved on the columns 11 to buffer the riveting pressure brought by the upper riveting knife holder.

[0022] Specifically, a copper ring feeding assembly and a terminal wire feeding assembly are provided on the lower riveting knife holder 10. The copper ring feeding assembly includes a first upright plate 14 provided on the lower riveting knife holder, a mounting base plate 15 provided on the first upright plate 14, and a copper ring feeding plate 17 provided on the mounting base plate 15 by two support blocks 16 spaced apart. The copper ring feeding plate 17 has a groove 171 for moving the copper ring strip. A feeding cover plate 18 is provided above the groove 171 to limit the feeding posture of the copper ring strip. The support block 16 located at the end of the mounting base plate 15 (in the direction of movement of the copper ring strip) extends out of the outer side of the copper ring feeding plate and has a supporting end face. There is a gap between the front end of the mounting base plate 15 and the upper copper ring feeding plate 17.

[0023] To achieve automated feeding of the copper ring strip, a first slide rail 19 is horizontally installed on the lower riveting knife holder 10. A movable base plate 20 is installed on the first slide rail 19. The movable base plate 20 does not contact the mounting base plate 15. A second vertical plate 21 is installed on the movable base plate 20. An adjusting plate 22 is installed on the upper riveting knife holder 12. An adjusting groove 221 is opened on the adjusting plate 22. The adjusting groove 221 is divided into three sections: the upper section is vertical, the middle section is inclined and slopes downward in the direction of copper ring movement, and the lower section is also vertical and has a U-shaped structure. A limiting roller 23 is installed at the upper end of one side of the second vertical plate 21. The limiting roller 23 can move up and down within the range of the adjusting groove 221.

[0024] More specifically, a second slide rail 24 is vertically arranged on the other side of the second vertical plate 21. A vertical moving plate 25 is arranged on the second slide rail 24 via a slider. A first spring hole 201 is opened on the moving base plate 20 below the slider. A first return spring (not shown in the figure) is arranged in the first spring hole 201. The first return spring can abut against the slider on the second slide rail. A horizontal moving plate 26 is arranged on the vertical moving plate 25. Two positioning pins 27 are arranged at intervals on the horizontal moving plate 26. Most of the horizontal moving plate 26 is located in the interval between the mounting base plate 15 and the copper ring feeding plate 17. The positioning pins 27 can pass through the copper ring feeding plate 17 so as to be inserted into the hole of the copper ring material strip and drive the material strip to move forward.

[0025] Meanwhile, a limiting plate 28 is vertically installed on the upper riveting knife holder 12. A limiting groove 281 is opened on the side of the limiting plate 28. A third upright plate 29 is installed on the mounting base plate 15. A first L-shaped connecting rod 30 is installed on the third upright plate 29. The bent part of the first L-shaped connecting rod is rotatably connected to the third upright plate 29 through a pin. One end of the first L-shaped connecting rod 30 is provided with a pressing protrusion 31 that matches the shape of the limiting groove 281, and the other end can abut against the upper surface of the vertical moving plate 25.

[0026] In addition, a mounting block 32 is provided on the third upright plate 29 near the limiting groove 281. A second spring hole 321 is provided on the mounting block 32. A second reset spring (not shown in the figure) is provided in the second spring hole 321. The second reset spring can abut against the first L-shaped connecting rod and is used to reset the first L-shaped connecting rod.

[0027] The automated feeding principle of the copper ring strip: In the initial state, the extrusion protrusion 31 is in the limiting groove 281. When riveting begins, the upper riveting knife holder 12 moves downward, and the extrusion protrusion 31 on the first L-shaped connecting rod is squeezed out of the limiting groove, forcing the connecting rod to rotate. The other end of the connecting rod moves downward, simultaneously driving the vertical moving plate 25 to move downward a certain distance. At the same time, the positioning pin 27 follows the vertical moving plate and disengages from the hole on the copper ring strip. Meanwhile, due to the existence of the adjusting groove 221, the positioning pin 27 moves a certain distance towards the feeding end of the copper ring strip under the drive of the moving base plate 20. When the copper ring at the riveting position... After pressing is completed, the upper riveting knife holder 12 resets upwards. At the same time, under the action of the second reset spring, the extrusion protrusion 31 moves into the limiting groove 281. The pressure on the vertical moving plate 25 disappears. Under the action of the first reset spring, the positioning pin is inserted into the hole of the next set of copper rings on the material strip. At the same time, under the action of the adjusting groove 221, the material strip moves forward a certain distance under the action of the positioning pin, realizing automated feeding. The distance moved is the horizontal interval between the upper and lower sections of the adjusting groove 221. This distance is determined according to the interval between two adjacent copper rings on the material strip and the distance between the front copper ring and the riveting position.

[0028] See Figures 16-18 After the copper ring is fed, it needs to be riveted. The support block 16 at the end of the mounting base plate 15 has a concave cross section. Two sets of riveting cutters 33 are set on the mounting base plate 15. The riveting cutters 33 are also set in the groove of the support block 16. During the riveting process, the position of the copper ring also needs to be fixed. A support plate 34 is vertically set on one side of one set of riveting cutters. A support groove 341 is opened on the support plate 34 to support and fix the end position of the copper ring.

[0029] Since the support plate 34 is positioned on the moving path of the copper ring strip, in order not to affect the movement of the copper ring strip, the support plate 34 is configured as a floating structure. Specifically, an extrusion plate 35 is provided on the limiting plate 28, and a second L-shaped connecting rod 36 is provided on the mounting base plate 15. The bend of the second L-shaped connecting rod 36 is rotatably connected to the mounting base plate via a pin. An extrusion roller 37 is provided at the upper end of the second L-shaped connecting rod 36 for cooperating with the extrusion plate 35, and the other end can abut against the bottom end of the support plate 34. In addition, on the support plate 34... A spring groove 343 is provided at the bottom end, and a spring hole corresponding to the spring groove is provided on the support block 16. A third return spring (not shown in the figure) is provided in the spring groove 343 and the spring hole. When the upper riveting knife seat 12 is pressed down, the extrusion plate 35 presses the extrusion roller 37 outward through the extrusion plate 35, forcing the second L-shaped connecting rod 36 to rotate. Its end drives the support plate 34 to rise to achieve support and positioning of the copper ring. When the upper riveting knife seat 12 rises to reset, the support plate 34 is reset downward through the third return spring, giving the next set of copper rings to be riveted space to move.

[0030] See Figures 12-15 The riveting structure of this application rivets a copper ring onto the terminal wire. Therefore, it is also necessary to synchronize the automated feeding of the terminal wire and the copper ring to save labor. Specifically, the terminal feeding assembly includes a platform 38 provided on one side of the lower riveting knife holder 10. Two positioning pins 39 are provided on the platform 38 for positioning and placing the carrier plate 40 containing multiple terminal wires.

[0031] More specifically, two second support plates 41 are horizontally spaced on the carrier plate 40. Multiple second support grooves 411 are evenly opened on the second support plates 41. In this embodiment, eight second support grooves 411 are provided to place eight terminal wires. A terminal cover plate 42 is provided on the second support plate 41. One end of the terminal cover plate 42 is rotatably connected to the second support plate 41 through a pin, and the other end is rotatably provided with a locking plate 43 for pressing the terminal cover plate.

[0032] To achieve synchronous movement of the terminal wire and the copper ring strip, a third slide rail 44 is horizontally arranged on the lower riveting knife holder 10, a connecting plate 45 is arranged on the movable base plate 20, an mounting plate 46 is arranged on the slider of the third slide rail 44, a locking rod 47 is arranged on the mounting plate 46, one end of the locking rod 47 is fixedly connected to the connecting plate 45, and the other end is provided with a locking protrusion 471. A guide plate 48 is vertically fixed on the side wall of the lower riveting knife holder 10, and a limiting rod 49 is arranged on the surface of the guide plate 48 facing the mechanism. Multiple limiting teeth 491 are evenly opened on the limiting rod 49 along its length direction. The limiting teeth 491 can cooperate with the locking protrusion 471 to fix the guide plate 48.

[0033] Specifically, the limiting tooth 491 has a guide part 492 and a clamping part 493. The clamping protrusion 471 can be clamped between two adjacent limiting teeth. The guide part 492 is a slope. The clamping protrusion also has a slope that cooperates with the guide part. The clamping part 493 is used for the clamping protrusion to drive the guide plate 48 forward a certain distance. The guide part 493 is used for the clamping protrusion to retract into the clamping part of the previous limiting tooth, thereby realizing that the guide plate moves synchronously with the copper ring strip.

[0034] In addition, the platform 38 is connected to the guide plate 48 via two sets of cross roller guides 381 to facilitate the vertical movement of the platform. A second mounting block 50 is provided on the guide plate below the platform 38, and a fourth return spring 51 is provided between the second mounting block 50 and the platform. During the downward pressing of the upper riveting knife holder, the platform must be moved downward to move the terminal wire to the riveting position. Therefore, a positioning plate 52 is provided on the mounting base plate 15. Multiple positioning slots 521 are evenly opened on the positioning plate 52. The number of positioning slots 521 is the same as the number of limiting teeth and the number of second support slots, which are eight in total. A positioning block 53 is provided on the platform. The positioning block 53 can move with the platform and is inserted into the positioning slot in sequence according to the number of riveting operations, thereby realizing the positioning of the platform.

[0035] The purpose of setting the platform to move up and down is to facilitate the cutting of the riveted copper ring strip. To achieve this function, a floating plate 54 is movably arranged on the side of the riveting cutter 33 opposite to the support plate 34. The floating plate 54 has a support end face for the copper ring strip to pass through. A third support plate 55 is arranged on the other side of the floating plate. A third support groove 551 for supporting the terminal wire is opened on the third support plate 55. A gap is left between the third support groove 551 and the floating plate below for the strip to pass through. A fifth return spring (not shown in the figure) is arranged between the third support plate 55 and the floating plate 54 and the mounting base plate 15 below. A protective plate 56 is arranged on the outside of the third support plate 55. The third support plate 55 and the floating plate 54 are both arranged in the groove of the support block 16.

[0036] In the initial state, the height of the third support groove 551 is higher than that of the copper ring strip, so it does not affect its feeding. After the upper riveting knife seat is pressed down, it drives the third support plate 55 to move downward, and at the same time drives the support plate 34 to move upward, so that the terminal wire in the third support groove is just in the groove of the copper ring. A cutting edge 552 is formed at the upper edge of the third support plate. During riveting, the cutting edge 552, the floating plate 54 and the lower cutting edge cooperate to cut off the excess material on the copper ring strip. The copper ring on the terminal wire is riveted, and the excess material continues to move forward with the strip.

[0037] See Figures 19-25A second mounting plate 57 is horizontally arranged on the lower end surface of the upper riveting knife holder 12. Two sets of through second limiting grooves 571 are opened on the bottom surface of the second mounting plate 57 along its length direction. The two sets of second limiting grooves 571 are arranged in parallel. A connecting block 58 is provided at one end of the second mounting plate 57. Two sets of through movable grooves 581 are opened on the connecting block 58. An adjusting rod 59 is inserted in the movable groove 581. One end of the adjusting rod 59 is connected to a wedge-shaped moving rod 60. The wedge-shaped moving rod 60 is movably inserted into the second limiting groove 571. A third mounting block 61 is provided below the second mounting plate 57. A mounting groove 611 is opened on the third mounting block 61. A wedge plate 62 matching the wedge-shaped moving rod 60 is provided at the upper end of the mounting groove 611. Multiple riveting upper knives 63 are provided below the wedge plate 62.

[0038] Specifically, the adjusting rod 59 is L-shaped, including a horizontally arranged connecting part 591 and a vertically arranged adjusting part 592. The connecting part 591 extends out of the connecting block 58 and is connected to the wedge-shaped moving rod 60. Two sets of spring grooves 582 are opened on the connecting block 58. A second buffer spring 583 is installed in the spring groove 582. The other end of the second buffer spring 583 abuts against the adjusting part 592. A screw mounting block 64 is provided at one end of the connecting block 58. A threaded hole 641 is opened on the screw mounting block 64. A locking screw (not shown in the figure) is installed in the threaded hole 641. The locking screw abuts against the adjusting part and is used to adjust the position of the wedge-shaped moving rod 60 in the horizontal direction.

[0039] In order to balance the forces on both ends of the wedge-shaped moving rod 60, a second limiting plate 65 is provided at the other end of the second mounting plate 57. A limiting pin 66 is provided on the second limiting plate 65. The limiting pin 66 is located in the second limiting groove 571. A third buffer spring 67 is sleeved on the limiting pin. The third buffer spring 67 abuts against the other end of the wedge-shaped moving rod.

[0040] To position the riveting blade and control its force, two second positioning pins 68 are vertically installed on the second mounting plate 57. The second positioning pins 68 pass through the third mounting block 61. Corresponding positioning holes 172 are opened on the copper ring feed plate 17 below for insertion and positioning. A fourth mounting block 69 is installed on the second mounting plate. An L-shaped buffer plate 70 is connected to the riveting blade 63. One end of the buffer plate 70 can pass through the fourth mounting block. A fourth buffer spring 71 is vertically installed between the buffer plate and the third mounting block.

[0041] In this embodiment, there are three riveting blades 63 arranged in sequence and their shapes are set according to the product to be riveted. One of the two outermost riveting blades is connected to the buffer plate 70 and is used to insert into the third support groove 551 below to press the terminal wire. The other blade is also provided with a second positioning pin 72. A second positioning hole 342 is opened on the support plate 34, and the second positioning pin 72 can be inserted into the second positioning hole 342. In addition, a pressure plate 73 is also provided on the buffer plate. A pressure groove 731 is opened on the pressure plate 73 to press the terminal wire on the platform and drive the platform to move down.

[0042] When the height of the riveting knife needs to be adjusted, the adjusting rod is moved forward by tightening the locking screw. The adjusting rod 2 moves the wedge moving rod, which in turn moves the wedge plate below downward. Since the wedge plate is connected to the riveting knife, the height of the riveting knife can be adjusted.

[0043] Since there are eight terminal wires on the platform in this embodiment, they need to move up and down with the platform at the same time. Therefore, multiple clearance openings 181 are opened on the feed cover plate 18 in front of the riveting position. Similarly, corresponding clearance openings are also opened on the copper ring feed plate behind the riveting position.

[0044] After riveting is completed, waste needs to be collected and processed. Therefore, a waste cover plate 74 is also provided on the support block 16 at the end for positioning and guiding the movement of waste. Meanwhile, a waste cutter 75 is provided on the third mounting block 61. The waste cutter 75 is positioned directly below the edge of the material strip, and a waste slide 76 is provided below this edge.

[0045] The working principle of the entire riveting mechanism: First, the eight sets of terminal strips 77 are placed on the carrier plate 40 by hand. Then, the carrier plate is placed on the platform 38. The copper ring strip 78 is fed through the groove of the copper ring feeding plate. Initially, the copper ring at the front end of the strip can be placed manually at the riveting position. Then, the riveting blade 63 is pressed down. At the same time as pressing down, the following actions are simultaneously achieved: (1) the support plate 34 rises, (2) the platform 38 is moved down by the pressure plate 72, (3) the floating plate 54 and the third support plate 55 move down under the action of the riveting blade, (4) due to the existence of the adjusting groove 221, the positioning pin 27 moves a distance towards the feeding end of the copper ring strip under the action of the moving base plate 20, (5) since the limiting rod 49 is connected to the moving base plate 20, the locking protrusion 471 moves backward, that is, towards the feeding end of the strip. Step back one space, (6) the material strip at the riveting point completes the cutting action; after the riveting is completed, the waste material cutting knife completes the cutting at the same time, and then the riveting upper knife resets. At this time, the following actions are carried out simultaneously: (1) under the action of the first reset spring, the positioning pin 27 is inserted into the hole of the next set of copper rings of the material strip, (2) the support plate 34 descends, (3) under the action of the adjustment groove 221, the material strip moves forward a distance under the action of the positioning pin, and moves the next set of copper rings to be riveted to the riveting position, (4) the floating plate 54 and the third support plate 55 move upward under the action of the fifth reset spring 56, (5) the platform rises and resets, (6) the locking protrusion 471 drives the platform to move forward one space; this cycle repeats until all eight terminal wires are riveted, the platform is removed manually, the platform is reset at the same time, and then another platform is replaced.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
