Description

Technical Field

[0001] This utility model relates to the field of high-frequency electric welding technology, specifically to a high-frequency welding device for terminals. Background Technology

[0002] Hardware terminals are made by stamping metal materials. When leaving the factory, the terminals are connected by connecting handles so that multiple terminals are arranged in a chain. After being rolled into a disc, they are convenient for transportation and subsequent crimping by a terminal crimping machine.

[0003] A terminal crimping machine is a machine used in wire processing. It crimps metal terminals onto the ends of wires and then makes them conductive, stably connecting two wires together without soldering. However, a terminal crimping machine needs to be replaced after one reel of terminals is used up. Replacing with a new terminal requires stopping the machine and then feeding the new terminal back into the crimping machine, which is not only inefficient but also very troublesome. To facilitate terminal feeding, workers connect the ends of two reels of terminals with tape, allowing new terminals to be fed in automatically. However, when the crimping machine reaches the tape connection, the machine needs to be stopped and the tape removed. Although this method avoids refeeding the terminals, it is still cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a high-frequency welding device for terminals that can weld two terminals together to facilitate crimping by a terminal crimping machine.

[0005] The technical solution of this utility model is to provide a high-frequency welding device for terminals with the following structure:

[0006] The device includes a worktable and slide rails, slide blocks, a drive unit, and a high-frequency welding unit mounted on the worktable. The slide rails are fixedly mounted on the worktable. There are two slide blocks slidably connected to the slide rails. Each slide block has an upwardly extending welding positioning boss at its top, which is parallel to the slide rail. The welding positioning boss is trapezoidal in shape, smaller at the top and larger at the bottom, and fits into the recessed part of the terminal for placing the terminal. The drive unit is connected to the slide blocks and drives the two slide blocks to move towards each other along the slide rails, so that the welding ends of the terminals on the two welding positioning bosses abut against each other. The high-frequency welding unit generates a high-frequency alternating magnetic field to weld the welding ends of the two terminals.

[0007] After adopting the above structure, the terminal high-frequency welding device of this utility model has the following advantages compared with the prior art:

[0008] In this invention, during welding, two terminals are fixed on corresponding welding positioning bosses. The two slides are driven to move towards each other by the drive unit, so that the welding ends of the terminals on the two welding positioning bosses abut against each other. Finally, the welding ends of the two terminals are welded by the high-frequency welding unit. In this way, the terminal crimping machine can work continuously without interruption, which not only saves time and effort but also has high efficiency.

[0009] Preferably, the welding positioning boss has a notch in the middle, and a vertically upward extending clamping plate is provided at the notch. The clamping plate is used to engage with the terminal gap to limit the axial movement of the terminal and prevent the terminal on the welding positioning boss from axially displacing, thereby avoiding welding failure.

[0010] Preferably, a mounting base is provided at the notch, and the mounting base has an elongated hole extending along the axial direction of the welding positioning boss for the connecting end of the bolt to pass through and be threaded into the screw hole of the slide block; the lower end of the clamping plate is connected to the mounting base and its position can be adjusted along the axial direction of the welding positioning boss with the mounting base. The user can make axial fine adjustments to the mounting base according to specific circumstances, and thus fine adjust the position of the clamping plate to ensure that the welding dimensions meet the requirements.

[0011] Preferably, the top of the card plate has a groove for the terminal connection handle to be inserted.

[0012] Preferably, the workbench is also provided with a clamping component for clamping the terminal onto the corresponding welding positioning boss to prevent the terminal from detaching from the welding positioning boss.

[0013] Preferably, the clamping assembly includes a bracket, a drive handle, a pressure claw, and a drive cylinder; the bracket and the drive cylinder are fixedly connected to the worktable, the middle part of the drive handle is rotatably connected to the bracket, one end of the drive handle is fixedly connected to the pressure claw, and the other end is movably connected to the output end of the drive cylinder, the drive cylinder is used to drive the drive handle to rotate, thereby driving the pressure claw to press down or lift up.

[0014] Preferably, the pressure claw has a pressure strip made of elastic material on one end face facing the terminal for pressing against the terminal. The elastic pressure strip can better press the terminal against the welding positioning boss without squeezing or deforming it, ensuring smooth subsequent processing.

[0015] Preferably, the workbench is also provided with a protective cover for covering the clamping assembly; the front end of the protective cover is open and is rotatably connected to a protective plate. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "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 utility model 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 utility model. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1-5 As shown, this utility model discloses a high-frequency welding device for terminals: including a workbench 1 and a slide rail 2, a slide block 3, a drive unit 4 and a high-frequency welding unit (not shown in the figure) disposed on the workbench 1.

[0026] The slide rail 2 is fixedly mounted on the worktable 1. There are two slide blocks 3, which are slidably connected to the slide rail 2. Each slide block 3 has a welding positioning boss 5 that extends upward and is parallel to the slide rail 2. The welding positioning boss 5 is trapezoidal in shape, which is smaller at the top and larger at the bottom. It fits into the recess of the terminal 6 and is used to place the terminal 6. The drive unit 4 is connected to the slide block 3 and is used to drive the two slide blocks 3 to move towards each other along the slide rail 2 so that the welding ends of the terminals 6 on the two welding positioning bosses 5 abut against each other. The high-frequency welding unit is used to generate a high-frequency alternating magnetic field to weld the welding ends of the two terminals 6.

[0027] The welding positioning boss 5 has a notch 51 in the middle, and a vertically upward extending clamping plate 7 is provided at the notch 51. The clamping plate 7 is used to clamp into the terminal gap 61 to limit the axial movement of the terminal 6. The top of the clamping plate 7 is provided with a groove 71 for the terminal connecting handle 62 to be clamped in, thereby preventing the axial displacement of the terminal 6 on the welding positioning boss 5 and thus avoiding welding failure.

[0028] A mounting base 8 is provided at the notch 51. The mounting base 8 has an elongated hole 81 extending along the axial direction of the welding positioning boss 5, which is used for the connecting end of the bolt to pass through and be threaded into the screw hole of the slide 3. The lower end of the clamping plate 7 is connected to the mounting base 8 and can be adjusted along the axial direction of the welding positioning boss 5 with the mounting base 8. In this way, the user can make axial fine adjustments to the mounting base 8 according to the specific situation, and then make fine adjustments to the position of the clamping plate 7 so that the welding dimensions meet the requirements.

[0029] In this invention, during welding, two terminals 6 are fixed on corresponding welding positioning bosses 5. The drive unit 4 drives two sliding blocks 3 to move towards each other, causing the welding ends of the terminals 6 on the two welding positioning bosses 5 to abut against each other. Finally, a high-frequency welding unit welds the welding ends of the two terminals 6. This allows the crimping machine to work continuously without interruption, saving time and effort while increasing efficiency. After welding, the terminals 6 are removed from the welding positioning bosses 5. Using the control button on the worktable 1, the drive unit 4 drives the two sliding blocks 3 to reset along the slide rail 2 in the opposite direction, facilitating the next welding operation.

[0030] The aforementioned drive unit 4 can be two stepper motors, each connected to one of the slides 3. The high-frequency welding unit has the same structural principle as the existing high-frequency welding machine. It converts the low-frequency AC power input from the power grid into high-frequency AC power. After the high-frequency current is applied to the inductor coil, it is converted into a high-frequency magnetic field using the principle of electromagnetic induction. This magnetic field acts on the terminal 6 located in the magnetic field, generating an induced current proportional to the magnetic field strength using the eddy current effect. When the eddy current flows inside the metal object, it generates heat using the principle of current heating effect, taking advantage of the inherent internal resistance, thereby completing the welding. This is existing technology and will not be described in detail.

[0031] For example Figure 2 and Figure 3 As shown, the workbench 1 is also equipped with a clamping component 9, which is used to clamp the terminal 6 onto the corresponding welding positioning boss 5 to prevent the terminal 6 from detaching from the welding positioning boss 5.

[0032] The clamping assembly 9 includes a bracket 91, a drive handle 92, a clamping claw 93, and a drive cylinder 94. The bracket 91 and the drive cylinder 94 are fixedly connected to the worktable 1. The middle part of the drive handle 92 is rotatably connected to the bracket 91. One end of the drive handle 92 is fixedly connected to the clamping claw 93, and the other end is movably connected to the output end of the drive cylinder 94. The drive cylinder 94 is used to drive the drive handle 92 to rotate, thereby driving the clamping claw 93 to press down or lift up.

[0033] The pressure claw 93 has a pressure strip 95 made of elastic material on one end face facing the terminal 6, which can better press the terminal 6 onto the welding positioning boss 5 without squeezing or deforming it, thus ensuring the smooth progress of subsequent processing.

[0034] The workbench 1 is also equipped with a protective cover 11, which is used to cover the clamping assembly 9; the front end of the protective cover 11 is open and is rotatably connected to a protective plate 12.

[0035] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
