Description

Technical Field

[0001] The invention relates to the technical field of high-frequency electric welding, in particular to a terminal high-frequency electric welding machine. Background Art

[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 shape. After being rolled into a disc, they are convenient for transportation and subsequent crimping by a terminal crimping machine.

[0003] The terminal crimping machine is a machine used in wire processing. It can press the hardware terminal to the end of the wire, and then make it conductive, so that two wires can be stably connected without welding. However, the terminal crimping machine needs to be replaced with a new one after a plate of terminals are finished. When replacing the new terminals, the machine needs to be paused, and then the terminals need to be reintroduced into the terminal crimping machine, which is not only inefficient but also very troublesome. In order to facilitate the introduction of terminals, workers will connect the ends of the two plates of terminals with tape, and the new terminals can be automatically introduced. However, when the terminal crimping machine is crimped to the tape connection, the equipment needs to be stopped and the tape removed. Although this method does not require reintroducing the terminals, it is still troublesome to operate, time-consuming and labor-intensive. Summary of the invention

[0006] After adopting the above structure, the terminal high frequency electric welding machine of the present invention has the following advantages compared with the prior art: The welding ends of the terminals are cut by the cutting mechanism so that their sizes meet the welding requirements, and then the two terminals are fixed on the corresponding welding positioning bosses. The two slides are driven by the driving unit to move toward each other so that the welding ends of the terminals on the two welding positioning bosses are abutted against each other, and 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 pausing, which not only saves time and effort but also has high efficiency.

The two cutting positioning bosses 23 are provided with a positioning plate 24 at one end facing each other, which is used to abut against the side wall of the terminal 4; the cutting assembly 22 is arranged between the two positioning seats 21, and is used to cut the terminal 4 extending out of the positioning plate 24.

[0028] Through the positioning effect of the cutting positioning boss 23 and the positioning plate 24, the cut terminal 4 can meet the size requirements of welding, avoiding the terminal gap 41 after welding from being too large or too small to affect the subsequent operation of the terminal crimping machine.

[0029] The cutting assembly 22 includes a driving motor 221 and two cutting knives 222. The driving motor 221 is fixedly connected to the workbench 1, and the cutting knives 222 are connected to the output shaft of the driving motor 221. The driving motor 221 is used to drive the cutting knives 222 to move vertically up and down to cut the terminals 4 extending out of the positioning plate 24.

[0030] A counterweight seat 223 is connected to the output shaft of the driving motor 221 above the cutting knife 222, and the counterweight seat 223 is provided with two through holes running through its upper and lower ends; a counterweight block 224 is provided above the counterweight seat 223, and two pressure blocks 225 matching the through holes are connected to the bottom of the counterweight block 224, and the lower ends of the two pressure blocks 225 pass through the corresponding through holes and are located on the outside of the two cutting knives 222, and are used to press the corresponding terminal 4 onto the cutting positioning boss 23.

After the welding is completed, the terminal 4 is removed, and the control button on the workbench 1 is pressed, and the drive unit 33 will drive the two slide seats 32 to reset in the opposite direction along the slide rail 31, which is convenient for the next welding.

[0033] The driving unit 33 can be two stepper motors, each of which is connected to one of the slides 32; the high-frequency welding unit has the same structural principle as the existing high-frequency welding machine, and converts the low-frequency alternating current input from the power grid into high-frequency alternating current. After the high-frequency current is added to the inductor, it is converted into a high-frequency magnetic field using the principle of electromagnetic induction, and acts on the terminal 4 in the magnetic field. The eddy current effect is used to generate an induced current proportional to the magnetic field strength. When the eddy current flows in the metal object, it will use the inherent internal resistance value and the principle of current thermal effect to generate heat, thereby completing the welding. This is a prior art, so it will not be described in detail.

[0034] A notch 351 is provided in the middle of the welding positioning boss 35, and a clamping plate 36 extending vertically upward is provided at the notch 351. The clamping plate 36 is used to be inserted into the terminal gap 41 to limit the axial position of the terminal 4, thereby avoiding axial displacement of the terminal on the welding positioning boss 35 and thus avoiding welding failure.

[0035] A mounting seat 37 is provided at the notch 351, and an oblong hole 371 extending along the axial direction of the welding positioning boss 35 is provided on the mounting seat 37, which is used for the connection end of the bolt to pass through and is threadedly connected to the screw hole of the slide seat 32, so that the user can fine-tune the axial direction of the mounting seat 37 according to the specific situation; the lower end of the clamping plate 36 is connected to the mounting seat 37, and the position can be adjusted along the axial direction of the welding positioning boss 35 with the mounting seat 37, thereby fine-tuning the position of the clamping plate 36 to make the welding size meet the requirements. A groove 361 is also provided on the top of the clamping plate 36 for the terminal connection handle 42 to be clamped in.

[0036] The high-frequency welding mechanism 3 further includes a pressing assembly 38 for pressing the terminal 4 onto the corresponding welding positioning boss 35 to prevent the terminal 4 from being separated from the welding positioning boss 35 .

[0037] The clamping assembly 38 includes a bracket 381, a driving handle 382, ​​a pressure claw 383 and a driving cylinder 384 (which can also be a linear motor); the bracket 381 and the driving cylinder 384 are fixedly connected to the workbench 1, the middle part of the driving handle 382 is rotatably connected to the bracket 381, one end of the driving handle 382 is fixedly connected to the pressure claw 383, and the other end is movably connected to the output end of the driving cylinder 384, and the driving cylinder 384 is used to drive the driving handle 382 to rotate, thereby driving the pressure claw 383 to press down or lift.

[0038] Among them, a pressure strip 385 made of elastic material is provided on one end surface of the pressure claw 383 facing the terminal 4, which can better press the terminal 4 onto the welding positioning boss 35 without squeezing and deforming it, ensuring smooth subsequent processing.

[0039] A grinder (not shown in the figure) can also be arranged on the workbench 1 to grind the welding position by means of the grinding wheel of the grinder to ensure the flatness of the welding position and prevent the terminal crimping machine from getting stuck when crimping the terminal.

[0040] The present invention cuts the welding end of the terminal 4 through the cutting mechanism 2 so that its size meets the welding requirements, and then fixes the two terminals on the corresponding welding positioning bosses 35, and drives the two slides 32 to move toward each other through the driving unit 33, so that the welding ends of the terminals 4 on the two welding positioning bosses 35 are abutted against each other, and finally the welding ends of the two terminals 4 are welded by the high-frequency welding unit. In this way, the terminal crimping machine can work continuously without pausing, which not only saves time and effort but also has high efficiency.

[0041] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
