[0044] The present application will be further described below in conjunction with the drawings and specific examples, so as to help understand the content of the present application. The methods used in the present application are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0045] The application provides a coiling and sealing machine. Figure 1 , 2 As shown in the figure, the whole machine is installed on the workbench 1 of the box body, and the inside of the workbench 1 is correspondingly integrated with other electrical accessories; and the universal wheels and the telescopic legs are installed at the lower part of the workbench 1 according to the requirement of the mobile configuration. The coiling and sealing machine mainly comprises a wire feeding mechanism 2, a wire cutting mechanism 4 and a wire pulling mechanism 5, which are mainly installed on one side of the workbench 1, wherein the wire outlet end of the wire feeding mechanism 2 is opposite to the wire pulling mechanism 5, and the wire cutting mechanism 4 is located between the wire feeding mechanism 2 and the wire pulling mechanism 5. Figure 3 As shown in the figure, the main body of the wire feeding mechanism 2 is a wire feeding machine, the bottom is a wire feeding mechanism mounting plate 201, a speed regulating motor 202 is installed laterally, and a wire wheel 203 is coaxially connected. Further, in order to detect whether the wire is fed, the tension state of the wire needs to be detected, so a wire feeding sensing rod 204 is further arranged below the wire wheel 203. The wire feeding sensing rod 204 is connected to the main body structure of the wire feeding mechanism 2 through an insulating pad, and correspondingly, the wire is crossed over the wire feeding sensing rod 204 after being stretched out from the wire wheel 203; when the wire pulling mechanism 5 pulls the copper wire, the copper wire contacts the wire feeding sensing rod 204, which can provide a corresponding electrical signal, indicating that the speed regulating motor 202 can rotate the wire. Further, as shown in the figure, the whole machine further comprises a straightening mechanism 3, which is located between the wire feeding mechanism 2 and the wire cutting mechanism 4, and the main body of the straightening mechanism 3 is a straightener. The copper wire passes through the wire hole 301, then passes through the vertical straightening wheel group 302 and the horizontal straightening wheel group 303 which are distributed orthogonally, and then is stretched out from the lead-in shaft 304. Figure 4

[0046] As shown in the figure, the wire cutting mechanism 4 is a cutting structure of opposite opening type, and a lower shear cylinder 401 is arranged at the lower part and fixed through a lower shear cylinder support 402. An active end connecting piece 403 is connected with a lower cutting blade 404. An upper shear cylinder 408 is arranged at the upper part, and a blade support 407 is connected with the lower shear cylinder support 402. The active end of the upper shear cylinder 408 is also connected with an upper cutting blade 406. The two cutting blades are limited by cutting blade guide blocks 405 on the two sides. Figure 5 Before cutting the wire, the copper wire passes through the straightening mechanism 3 and the wire cutting mechanism 4 (the two cutting blades are in a separated state) in sequence, and then is overlapped on the active end of the wire pulling mechanism.

[0047] As shown in the figure, the main body of the wire pulling mechanism 5 is a single-shaft movable platform 501, the active end of which is provided with a rebound type clamping jaw, specifically a wire pulling clamping jaw cylinder 502, two wire pulling clamping fingers 504 are fixed through a clamping finger support 503, and a clamping finger spring 505 is arranged between the two wire pulling clamping fingers 504, so that the clamping fingers can be naturally opened in the reset process.

[0048] Figure 6

[0049] ​​​like Figure 2 As shown, a wire picking and placing mechanism 6 is provided on the side of the wire pulling mechanism 5 for picking up and placing the cut wire; preferably, combined with Figure 7 As shown, the main body of the wire pick-and-place mechanism 6 is a 3-axis moving platform. Its power unit, except for the first platform 601 which uses a combination of a servo motor and a lead screw, uses cylinders for the other two platforms. Specifically, the piston rod of the lifting cylinder 604 at the lifting end is fixedly connected to a vertical slide plate 605 and slidably connected to the upright plate 603 via a linear guide rail 606. A wire pick-and-place gripper cylinder 607 is horizontally fixed on the vertical slide plate 605, maintaining the gripper fingers in a vertical direction. Correspondingly, the single-finger structure of the wire pick-and-place gripper 608 is designed as a fork-shaped structure, allowing for horizontal gripping of the cut copper wire and transfer to the tooling. Furthermore, because this mechanism requires high operational precision to ensure accurate pick-and-place, a position detection sensor and a limit structure are added to the movement trajectory. Specifically, as shown in the figure, a photoelectric switch and a zero-position plate are installed between the second platform 602 and the first platform 601, and a photoelectric switch and a zero-position plate are also installed between the rodless cylinder slider of the second platform 602 and the base. Furthermore, a limit plate is added to the limit position of the slider stroke of the rodless cylinder on the second platform 602, and limit screws and a buffer are installed.

[0050] A turntable mechanism 7 is provided on the side of the movable end of the wire feeding mechanism 6; four tooling fixtures 704 are evenly arranged along the circumferential direction on the turntable mechanism 7. And as... Figure 8 As shown, the turntable mechanism 7 is surrounded by a wire feeding station 712, a capping station 713, a ring-forming and sealing station 714, and a wire picking station 715, all evenly distributed. It should be noted that these stations refer to fixed areas on the workbench 1, not specific areas or attachments on the turntable, and therefore do not change with the rotation of the turntable. The wire feeding / picking mechanism 6 is located in the wire feeding station 712.

[0051] Preferred, combined Figure 9 , 10As shown, the drive unit of the turntable mechanism 7 is an AC geared motor 701, whose output shaft is connected to a cam divider 702, driving the turntable 703 to rotate in four positions. A column is located in the middle of the turntable 703 and is fixed relative to the worktable 1. A cylinder mounting plate 705 with three extending protrusions is installed on the upper part, corresponding to the wire feeding station 712, the ring forming and sealing station 714, and the wire picking station 715, respectively. The main body of the tooling 704 on the turntable mechanism 7 is a cuboid copper wire support platform 7043, with wire support brackets 7045 on both sides along the horizontal direction. To prevent the fork-shaped structure of the aforementioned wire feeding and picking fingers 608 from interfering with the wire support brackets 7045 during the wire feeding process, a through slot is designed between the inner side of the wire support bracket 7045 and the copper wire support platform 7043. Each fixture 704 has a lower welding electrode 7044 vertically positioned at its front. A coiling mandrel is vertically positioned on the upper surface of the lower welding electrode 7044, forming a telescopic relationship with it and returning to its original position via a compression spring. A spring-loaded reciprocating push rod is located on the rear side of the coiling mandrel. Specifically, two parallel zigzag push rods 7046 are used, with a contoured arc-shaped front end to push the copper wire forward and cause its middle section to bend against the coiling mandrel, ultimately forming the state shown in the figure (like an old-fashioned bobby pin). Correspondingly, a slider is installed on the upper surface of the fixture 704, and the zigzag push rods 7046 are slidably connected to it, with a compression spring for buffering. A fixing plate 7049 is installed at the rear of the fixture 704, and a return spring 7048 is provided between the slider and the fixing plate 7049, serving to return the zigzag push rods 7046 and the slider to their original positions. Furthermore, the slider is provided with an upwardly bent hook plate 7047. Correspondingly, a return cylinder 706 is fixedly hung horizontally on the lower surface of each protruding edge of the cylinder mounting plate 705. The movable end of the return cylinder 706 is equipped with a return baffle 707, which overlaps with the hook plate 7047 in the current position. Further still, each tooling 704 has a spline shaft 7042 at its lower part, and a spline bearing 7041 is correspondingly installed at the mounting position on the turntable 703 of the turntable mechanism 7. The spline shaft 7042 and the corresponding spline bearing 7041 cooperate to form a sliding connection. A spring is also fitted on the spline shaft 7042, located between the bottom surface of the tooling 704 and the flange structure of the spline bearing 7041, for buffering the return action.

[0052] The head-sealing station 713 is equipped with a head-sealing mechanism 8, the main body of which is a butt welding machine; preferably, such as Figure 11As shown, the end cap mechanism 8 is mounted on a one-dimensional slide table 801, and an end cap gripper cylinder 802 is horizontally mounted on its movable end. The opening and closing direction is horizontal, and each gripper has an electrode at its end, namely a left electrode 805 and a right electrode 806. A limiting mechanism is provided at the front end face of the end cap gripper cylinder 802 to correct the position of the copper wire after bending. The limiting mechanism includes an upper limit block 807 and a lower limit block 808, which are slidably connected to the cylinder end face via a slide rail. The limiting blocks are specifically driven to open and close by limiting cylinders. Correspondingly, the upper limit block 807 is driven by an upper limit cylinder 803, and the lower limit block 808 is driven by a lower limit cylinder 804.

[0053] The coiling and sealing station 714 is equipped with a coiling mechanism 9 and a sealing mechanism 10. The main body of the coiling mechanism 9 is a twisting machine; preferably, such as... Figure 12 As shown, the coiling mechanism includes a one-dimensional motion platform 901, and a rotary mechanism is installed at the movable end, including a stepper motor 902 and a bearing housing 903, which transmit power through a gear pair. At the end, a coiling gripper cylinder 905 is coaxially installed through a mounting clamp 904. Its gripper 906 is used to clamp the end of the copper wire and performs a coiling operation as it rotates.

[0054] The main body of the sealing mechanism 10 is also a welding machine; preferably, it is combined with... Figure 1 , 2 The sealing mechanism 10 shown in Figures 13-15 is suspended above the movable end of the forming mechanism 9 via a gantry frame. The upper part of the sealing mechanism 10 is equipped with a downward-pressing cylinder 1001. An anti-torsion frame is fixed to the lower end of the cylinder body. The piston rod passes downward through the anti-torsion frame via a bushing and connects to the first lead screw adjuster. A guide shaft limits and prevents torsion between the first lead screw adjuster and the anti-torsion frame. The upper connecting plate 1002 of the first lead screw adjuster is connected to the bushing and fixed to the lead screw slider 1003 with bolts. The lead screw base is fixed to the upper electrode post 1005, and the lower end is equipped with an upper welding electrode 1006. The position of the upper welding electrode 1006 can be finely adjusted by adjusting the first handwheel 1004. A spring-loaded pressure rod is also installed on the side of the upper welding electrode 1006. A lower electrode is installed below the upper welding electrode 1006, and its lower electrode post 1007 is connected to the second lead screw adjuster via a lower connecting plate 1008, together fixing the electrode mounting base 1010. The position of the lower electrode post 1007 can be finely adjusted by adjusting the second handwheel 1009.

[0055] The wire-taking station 715 is equipped with a discharge mechanism 11. To facilitate clamping, an ejection mechanism is also provided on the upper part of the turntable mechanism 7. The main body of this mechanism is fixed to a vertically placed ejector cylinder 709 via an adapter plate 708, with its movable end facing downwards. An ejector cylinder 710 is mounted on this cylinder, its movement direction facing the mandrel. When pressed down, it abuts against the center area of ​​the mandrel, causing the welded copper wire to detach from the lower electrode, facilitating the discharge mechanism to eject the copper wire and preventing it from sticking to the lower electrode. A material-taking support column 711 is also located directly below the ejector cylinder 710 and fixed to the table surface to limit the descent of the entire fixture 704.

[0056] The main body of the discharge mechanism 11 is a multi-axis platform or industrial robot, and a gripping mechanism is installed at its end. For example... Figure 16 As shown, in this embodiment, since the turntable mechanism 7 adds a copper wire ejection mechanism at the wire taking station 715, the material discharge mechanism 11 preferably adopts a two-dimensional motion platform 1101, and a material picking claw cylinder 1102 is installed at the end for picking up and placing the processed copper wire, and the connector of the motion cylinder in the two-dimensional motion platform is selected as a floating connector 1103.

[0057] Work process

[0058] 1. When the wire pulling mechanism pulls the wire backward, the copper wire becomes taut and contacts the wire feeding induction shaft, the electrical contacts are connected, the speed-regulating motor actuates, and the wire is fed out according to the set time. In addition, before being pulled backward by the wire pulling mechanism, the copper wire passes through a straightening mechanism to straighten it in both horizontal and vertical directions.

[0059] 2. After the wire pulling mechanism pulls the wire to a certain length, the wire cutting mechanism activates; the cutting blade closes to cut the copper wire.

[0060] 3. The wire pick-and-place mechanism operates by moving the wire pick-and-place clamp to the copper wire support fixture on the turntable mechanism and then returning to its original position. At the same time, after the copper wire is placed, the return cylinder of the turntable mechanism's wire placement station extends, causing the folding push rod to move forward and fold the copper wire around the coiling core rod.

[0061] 4. The turntable mechanism rotates to the head station, the head mechanism moves, the upper and lower limit cylinders move to the forward position, welding is performed after the position is reached, the finger clamping cylinder is unloaded after welding is completed, and the mechanism is reset.

[0062] 5. When the turntable mechanism rotates to the ring forming and sealing station, the ring forming mechanism is activated first. The gripper cylinder closes to clamp the copper wire, and the stepper motor rotates, driving the copper wire to rotate and perform ring forming.

[0063] 6. After the ring forming is completed, the sealing mechanism activates, the cylinder lowers, and during the downward movement, the pressure rod first presses to the highest point of the fixture. As it continues to descend, the upper welding electrode presses down on the copper wire until the lower welding electrode of the turntable mechanism reaches the lower electrode post and stops. After the pressure is fully applied, the welding power supply performs welding. After welding is completed, the sealing mechanism resets, and the ring forming mechanism also resets simultaneously.

[0064] 7. The turntable rotates to the material picking position, the pin cylinder of the turntable mechanism presses down, the discharge mechanism is activated, the gripper cylinder closes to clamp the copper wire, and moves it into the discharge funnel, and then resets.
