Description

Technical Field

[0001] This application relates to the field of high-speed automated cable welding technology, specifically to a wire clamp for magnetic levitation welding. Background Technology

[0002] In the field of electronics manufacturing, wire-to-terminal soldering is a common and critical process. Traditional soldering processes typically use separate fixtures to hold the wire and terminal separately. After pretreatment (such as stripping and shaping), the wire is aligned and assembled with the terminal fixture before soldering. While this type of separate fixture achieves the basic function, it has the following significant drawbacks:

[0003] Because wire clamps and terminal clamps need to be set separately, the overall structure occupies a lot of space, which is not conducive to the layout of high-density production lines.

[0004] It requires multiple feeding, alignment and assembly processes, frequent manual intervention, and low production efficiency;

[0005] Most processes rely on manual operation, making it difficult to achieve full automation and ensuring consistency and stability. Summary of the Invention

[0017] In one embodiment, a pull-out drive assembly for driving the limiting rod to perform translational movement is also connected to one side of the wire clamp seat. The pull-out drive assembly includes a movable groove three opened on one side of the wire clamp seat, a cover plate fixed to the opening of the inner wall of the movable groove three, a hollow ring body one rotatably connected to one side of the cover plate, a slanted top block one fixed to one side of the hollow ring body, a transmission part connected in the movable groove three for driving the hollow ring body one to rotate, a motor fixed to one side of the cover plate and whose output shaft is connected to the transmission part, a control box fixed to one side of the cover plate, a hollow ring body two fixed to the outside of the pull-out part, and a slanted top block two fixed to one side of the hollow ring body two and cooperating with the slanted top block one.

[0036] 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.

[0037] 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.

[0038] Example:

[0039] Please see Figures 1-12 This application provides a technical solution: a wire clamp for magnetic levitation welding, including a wire clamp base 3;

[0040] The wire clamp base 3 is also internally connected to a wire clamping assembly 5 for clamping the wire. A guide rail 31 is fixedly connected to one side of the wire clamp base 3, and a terminal block 4 for positioning the terminal is slidably mounted on the guide rail 31.

[0041] The wire clamp 3 is also movably connected to a positioning component 6 for positioning the terminal block 4; when the positioning component 6 cancels the positioning of the terminal block 4, the positioning component 6 can fall freely on the guide rail 31 to achieve avoidance and perform pre-processing of the wire; when the terminal block 4 slides on the guide rail 31 and the upper end of the terminal block 4 is flush with the upper end of the wire clamp 3, it is positioned by the positioning component 6 to achieve the alignment of the terminal and the wire and perform welding processing;

[0042] By integrating terminals and wires onto a fixture for integrated loading, and then adjusting the axial position of the terminal block 4, continuous terminal assembly, wire processing, and welding testing can be achieved.

[0043] The specific method is as follows: First, the terminal block 4 moves upward along the guide rail 31 until its upper end is flush with the upper end of the wire clamp 3. The positioning component 6 positions the terminal block 4 so that it falls freely without being affected by gravity. The terminal (consisting of an iron shell and a rubber core placed inside the iron shell) is then placed into the terminal block 4. Next, the positioning component 6 is controlled to release the positioning of the terminal block 4, and the terminal block 4 falls freely along the guide rail 31 due to gravity. Then, the wire is placed on the upper end of the wire clamp 3 and clamped by the wire clamping component 5. Since the terminal block 4 falls and is not flush with the wire clamp 3, when the wire clamp 3 moves to the wire pre-processing station, one end of the wire clamped on the upper end of the wire clamp 3 can be pre-processed (aluminum foil stripping, etc.). (Mechanical insulation removal, ground wire shaping, etc.); When one end of the wire is pre-treated and moved to the welding station, a cylinder is set below the terminal block 4 at the welding station. The cylinder can lift the terminal block 4 and make its upper end level with the upper end of the wire clamp 3, and the positioning component 6 positions the terminal block 4. At this time, the pre-treated end of the wire on the wire clamp 3 can enter the terminal inside the terminal block 4 for welding. After welding, the positioning component 6 releases the restriction on the terminal block 4, and the terminal block 4 falls freely. At this time, the terminal is welded to one end of the wire. The terminal will not fall with the terminal block 4. The clamping component 5 is released from the wire, and the wire with the welded terminal is taken out to complete the entire processing process.

[0044] Existing fixtures generally employ a split-type design, such as... Figure 12As shown, the wire and terminal are placed separately and clamped by two clamps respectively. After the wire is pre-treated, the wire clamp and terminal clamp are assembled and then welded. This type of clamp is large in size, the loading action is complicated, time-consuming, and requires multiple manual interventions. Compared with the clamps in the prior art, this application uses a one-time loading (both terminals and wires are placed on the clamp at once), and then uses automated actions to adjust the axial position of the terminal block 4. This allows for automated processing after one loading (completing terminal assembly / wire processing / welding test / etc.), without multiple manual interventions. At the same time, the carrier size is small, the loading action is simple, and the time consumption is less.

[0045] like Figure 1 As shown, a buffer pad 34 for contacting the lower end of the terminal block 4 is fixedly connected to one side of the wire clamp seat 3. The buffer pad 34 can reduce the impact force when the terminal block 4 falls and buffer and absorb the force generated by the falling terminal block 4. It can be made of materials such as damping pads. A base 1 is fixedly connected to the lower end of the wire clamp seat 3. A magnetic levitation carrier base 2 that cooperates with the magnetic levitation carrier line is fixedly connected to the inner wall of the base 1. The magnetic levitation carrier base 2 matches the magnetic levitation carrier line to realize magnetic levitation carrier movement. Magnetic levitation automated carrier technology has been applied to automated production lines in the existing technology and is a mature existing technology, which will not be described in detail here.

[0046] like Figure 3 and Figure 4 As shown, the wire clamping assembly 5 includes a clamping block 51 rotatably connected to the upper end of the wire clamping seat 3, a second movable groove 56 opened inside the wire clamping seat 3, a back plate 57 fixed to one side of the wire clamping seat 3 and covering the opening of the second movable groove 56, a lifting plate 52 slidably connected in the second movable groove 56, a travel limiting groove 53 opened inside the lifting plate 52, a limiting pin 54 with one end passing through the travel limiting groove 53 and fixed to the inner wall of the second movable groove 56, and a spring 55 located in the second movable groove 56 with both ends connected to the lower end of the lifting plate 52 and the inner wall of the second movable groove 56 respectively. One end of the lifting plate 52 is rotatably connected to one end of the clamping block 51, and the upper end of the wire clamping seat 3 is fixedly connected to a wire clamping part 32 that cooperates with the clamping block 51 to clamp the wire.

[0047] Cylinders are installed in both the wire installation process and the terminal welding process. When the wire clamp 3 moves below the cylinder, the telescopic end of the cylinder extends and contacts the upper end of the lifting plate 52, pushing the lifting plate 52 downward and squeezing the spring 55. When the lifting plate 52 moves downward, it can drive the clamping block 51 to rotate at the upper end of the wire clamp 3, thereby causing the clamping block 51 to flip. At this time, the clamping block 51 and the wire clamping part 32 open, so that the wire can be put into the wire clamping part 32 or the welded wire can be taken out of the wire clamping part 32. Through the cooperation of the limiting pin 54 and the stroke limiting groove 53, the stroke of the lifting plate 52 can be limited.

[0048] like Figure 7 As shown, a slider 41 is fixedly connected to one side of the terminal base 4 and slides on the guide rail 31. A terminal limiting groove 43 for positioning the terminal is opened at the upper end of the terminal base 4. When feeding the terminal, the terminal can be placed in the terminal limiting groove 43.

[0049] like Figure 5 , Figure 6 , Figure 7 and Figure 11 As shown, a positioning groove 42 is provided on one side of the terminal block 4; the positioning component 6 includes a movable groove 33 inside the online clamp 3, a hollow retaining ring 65 fixed at the opening of the inner wall of the movable groove 33, a limiting rod 62 that is movably inserted into the movable groove 33 and extends outward from the hollow retaining ring 65 at one end, and a pull-out part 61 fixed on the other end of the limiting rod 62.

[0050] The end of the limiting rod 62 that is inserted into the positioning groove 42 has an inclined surface 64.

[0051] The terminal block 4 is also fixedly connected to a guide sleeve 66, and the limiting rod 62 is movably inserted into the guide sleeve 66;

[0052] The pull-out part 61 can be pulled and retracted by the pull-out part 61 and the limiting rod 62. One end of the limiting rod 62 is inserted into the positioning groove 42, which can limit the terminal block 4 and prevent the terminal block 4 from falling freely. When the limiting rod 62 is pulled, one end of the limiting rod 62 is pulled out from the positioning groove 42, at which point the limitation on the terminal block 4 is released, and the terminal block 4 falls freely. The guide sleeve 66 is used to guide the limiting rod 62.

[0053] like Figure 11 As shown, a limiting ring 63 is also fixedly connected to the outside of the limiting rod 62, and a second spring 621 is also sleeved on the outside of the limiting rod 62. The two ends of the second spring 621 are respectively connected to one side of the guide sleeve 66 and one side of the limiting ring 63.

[0054] When the pulling part 61 is pulled, causing the limiting rod 62 to move towards the guide sleeve 66, the limiting ring 63 can squeeze the second spring 621, causing the second spring 621 to compress. At this time, one end of the limiting rod 62 is pulled out from the positioning groove 42, and the limiting of the terminal seat 4 is released, allowing the terminal seat 4 to fall freely. When the pulling part 61 is released, the second spring 621 generates a force that pushes the limiting ring 63 towards the hollow stop ring 65. The limiting ring 63 drives the limiting rod 62 and the pulling part 61 to reset. The hollow stop ring 65 is used to block the limiting ring 63, preventing the limiting ring 63 from moving out of the movable groove 33.

[0055] like Figures 8-11 As shown, the wire clamp seat 3 is also connected to a pull-out drive assembly 7 for driving the limit rod 62 to perform translational movement. The pull-out drive assembly 7 includes a movable groove 3 71 opened on one side of the wire clamp seat 3, a cover plate 75 fixed to the opening of the inner wall of the movable groove 3 71, a hollow ring 1 78 rotatably connected to one side of the cover plate 75, a slanted top block 1 781 fixed to one side of the hollow ring 1 78, a transmission part connected in the movable groove 3 71 for driving the hollow ring 1 78 to rotate, a motor 76 fixed to one side of the cover plate 75 and whose output shaft is connected to the transmission part, a control box 77 fixed to one side of the cover plate 75, a hollow ring 2 79 fixed to the outside of the pull-out part 61, and a slanted top block 2 791 fixed to one side of the hollow ring 2 79 and cooperating with the slanted top block 1 781.

[0056] The transmission unit includes a gear 72 rotatably connected in the movable slot 71 and a gear 73 meshing with the gear 72, and a connecting ring 74 fixed to one side of the gear 73. One side of the connecting ring 74 passes through the cover plate 75 and is fixed to the hollow ring body 78. The output shaft of the motor 76 passes through the cover plate 75 and is connected to the gear 72.

[0057] This application allows for more than just manual adjustment of the pulling motion of the limit rod 62. To automate the lifting motion of the terminal block 4, a cylinder can be used to drive the terminal block 4 upwards. For example, a sensor and cylinder can be installed at the welding station. When the fixture moves to the loading or welding station, the sensor sends a signal and controls the cylinder to extend. The extension end of the cylinder contacts the bottom of the terminal block 4, causing it to rise. At this time, the second inclined surface 44 on the terminal block 4 contacts the first inclined surface 64 at one end of the limit rod 62. The terminal block 4 then presses against the limit rod 62 and pushes it towards the hollow retaining ring 65, causing the limit rod 62 to extend. One end enters the active slot 33. When the positioning slot 42 moves to one side of the limiting rod 62, the spring 621 pushes the limiting rod 62 to reset and insert the limiting rod 62 into the positioning slot 42, completing the lifting and positioning action of the terminal block 4. By automatically controlling the limiting rod 62 to pull it out of the positioning slot 42, the descent action of the terminal block 4 can be automatically realized. The movement of the limiting rod 62 is automatically controlled by the pull-out drive assembly 7. Specifically, the control box 77 in this embodiment consists of a control board, an RFID tag, and a battery module. The control board is equipped with a signal receiving module and can control the operation of the motor 76. The battery module is used to provide power for the operation of the motor 76 and the control board. The required electrical energy; RFID readers are also installed at the welding station. When the fixture moves to the welding station, the reader reads the unique ID, the system determines whether it is the designated station, and sends a trigger signal; the control board receives the signal and controls the motor 76 to work, driving gear 1 72 to rotate. Gear 1 72 rotates, driving gear 2 73, connecting ring 74, and hollow ring 1 78 to rotate. The rotation of hollow ring 1 78 pushes inclined push block 2 791 to move through inclined push block 1 781. The movement of inclined push block 2 791 can drive hollow ring 2 79 and pulling part 61 to perform translational movement. Pulling part 61 drives the limiting rod 62 to translate and causes one end of the limiting rod 62 to move out of the positioning groove 42. The limit on terminal block 4 is removed, completing the automated drive for terminal block 4 to fall; when the first inclined block 781 separates from the second inclined block 791, the second spring 621 drives the limit rod 62 to reset; it should be noted that the limit rod 62 has a flange on the outside, and the guide sleeve 66 has a slide to accommodate the flange inside. The flange and slide structure are not shown in the attached drawings of this application. The specific function of the flange is to prevent the limit rod 62 from rotating inside the guide sleeve 66 when the limit rod 62 is translating. This design is a commonly used translational anti-rotation design, which will not be elaborated here; in this way, when the first inclined block 781 contacts the second inclined block 791, it will not drive the limit rod 62 to rotate.
