[0022] The specific embodiment of the present application is explained below with reference to the accompanying drawings.

[0023] As shown in the accompanying Figure 1 , a high-frequency welding machine with high safety performance comprises a rack 1, a workbench 3 and a translation mechanism 4, wherein a machine head 2 is arranged on the rack 1 to be lifted and lowered, and the machine head 2 of the high-frequency welding machine converts the power frequency current into high-frequency current through an electronic tube or a transistor during use, and generates a high-frequency electromagnetic field through a high-frequency oscillation circuit. The molecules of the material to be welded move violently and rub against each other under the action of the high-frequency electromagnetic field, thereby generating heat. When the temperature of the material reaches the melting point, the surface of the material begins to melt. Under the action of pressure, the molten materials penetrate and fuse with each other, and form a firm welded joint after cooling.

[0024] As shown in the accompanying Figure 1 and Figure 2 , the upper surface of the rack 1 is provided with an inwardly recessed mounting groove 11, and the machine head 2 is located above the mounting groove 11. The translation mechanism 4 is arranged in the mounting groove 11 and is used to drive the workbench 3 to move forward and backward and to lift and lower. During use, the workbench 3 is driven by the translation mechanism 4 to move backward and away from the machine head 2. Then, the workpiece is placed on the workbench 3. As shown in the accompanying Figure 7 , the workbench 3 drives the workpiece to move forward to be directly below the machine head 2 through the translation mechanism 4, and the workbench 3 drives the workpiece to rise at the same time. Finally, the machine head 2 is lowered to press the workpiece for welding. In this process, since the workbench 3 is away from the machine head 2 when the workpiece is placed, it is avoided that people put their hands deep into the area below the machine head 2 of the high-frequency welding machine, thereby reducing the probability of the hands approaching the high-temperature area, greatly reducing the occurrence of scalding accidents caused by operation errors or insufficient protection, and ensuring production safety and efficiency. In addition, the height of the machine head 2 can also be adjusted in advance, so that the machine head 2 directly presses the workpiece for welding after the workbench 3 drives the workpiece to rise, thereby reducing the processing steps and further improving the production efficiency.

[0025] As shown in the accompanying Figure 3 and Figure 4As shown, the translation mechanism 4 includes two supports 41 and a translation frame 42 between the two supports 41, the support 41 includes a vertical plate 411 and a horizontal plate 412 perpendicular to each other, the horizontal plate 412 is arranged at the bottom of the vertical plate 411, and the translation frame 42 includes two first supporting plates 421 and two second supporting plates 422 arranged at both ends of the first supporting plate 421. Among them, the vertical plates 411 of the two supports 41 are symmetrically arranged on the left and right inner walls of the mounting groove 11, and the translation frame 42 is arranged on the horizontal plates 412 of the two supports 41 and moves forward and backward. Specifically, the bottom surface of the two first supporting plates 421 of the translation frame 42 is provided with a rack 424, and the two horizontal plates 412 are provided with a gear 415, the gear 415 is arranged in the mounting groove 11 and rotates, and the gear 415 is engaged with the rack 424. In use, the motor arranged in the mounting groove 11 drives the gear 415 to rotate, and the translation frame 42 moves forward and backward with the workbench 3 between the two supports 41 under the action of the rack 424.

[0026] As shown in the accompanying drawings Figures 4 to 6 As shown, the workbench 3 is arranged above the translation frame 42, and the workbench 3 can move forward and backward and lift relative to the translation frame 42. Specifically, the workbench 3 has four corners and each corner is hinged to a connecting arm 31, and the other end of each connecting arm 31 is hinged to the two ends of the first supporting plate 421. And the connecting arm 31 on the front end of the workbench 3 is provided with a guide wheel 32, and the guide wheel 32 is arranged in the sliding groove 43 on the side surface of the vertical plate 411. The sliding groove 43 includes a translation groove 431 and a lifting groove 432 perpendicular to each other, the translation groove 431 is communicated with the lifting groove 432, and the lifting groove 432 is located on the upper side of the translation groove 431, and the translation groove 431 is arranged in the front and back direction of the support 41. When the translation frame 42 moves forward and backward to drive the workbench 3 to move forward and backward, the guide wheel 32 rolls along the sliding groove 43 to drive the workbench 3 to rise and fall, and in the process, the connecting arm 31 rotates, so that the workbench 3 moves forward and backward relative to the translation frame 42.

[0027] Further, the bottom surface of the two first supporting plates 421 of the translation frame 42 is provided with a sliding block 414, and the upper surface of the horizontal plate 412 is provided with a sliding rail 413, and the sliding block 414 is sleeved outside the sliding rail 413 and moves forward and backward, and the sliding block 414 can accurately move in a straight line along the axis of the sliding rail 413, providing reliable guidance and positioning function for the translation frame 42. This guiding action ensures the accuracy and stability of the translation frame 42 during movement, so that the translation frame 42 can move according to the predetermined path. Preferably, the bottom surface of the two first supporting plates 421 of the translation frame 42 is provided with a fixed plate 423, and the sliding block 414 is installed on the fixed plate 423, which improves the installation firmness of the sliding block 414.

[0028] In summary, in use, first make the workbench 3 move backward under the drive of the translation mechanism 4, away from the machine head 2, then place the workpiece on the workbench 3, make the workbench 3 move forward with the workpiece to the position directly below the machine head 2 through the translation mechanism 4, at the same time, when the translation frame 42 moves the workbench 3 back and forth, the guide wheel 32 rolls along the sliding groove 43 to drive the workbench 3 and the workpiece to rise, finally, the machine head 2 is lowered to press the workpiece to perform fusion. In the process, since the workbench 3 is away from the machine head 2 when the workpiece is placed, it is avoided that people put hands into the position below the machine head 2 of the high-frequency fusion machine, thereby reducing the probability that hands approach the high-temperature area, greatly reducing the occurrence of scalding accidents caused by operation errors or insufficient protection, and guaranteeing production safety and efficiency.

[0029] The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited to this, and any non-substantial change of the utility model by using the concept should belong to the act of infringing the protection range of the utility model.
