TW200948520A - Combined device of ultrasonic welding and spin welding - Google Patents

Abstract

The present invention relates to a combined device of ultrasonic welding and spin welding which makes the welding of workpieces obtain better sealing effect, the machine mainly provided with a spinning device composed of a turntable, a base, and a motor. The base is coupled to a rotating shaft of the motor. A lower workpiece is fixed on the base. When the lower workpiece is driven by the motor to perform high speed rotation and is contacted with an upper side fixed workpiece, the contact face therebetween is melted due to heat generated by friction. An upper ultrasonic wave generator is then pressed on the upper workpiece and generates ultrasonic vibration to make the melted material mutually mixed. Afterwards, the motor is braked to stop rapidly, so that the contact face after being cooled down and solidified obtains a more compact effect, so as to achieve the efficacy of better joint density.

Description

200948520 IX. Description of the invention: [Technical field of invention]: The present invention relates to a combination of ultrasonic welding and rotary welding, the main technology and purpose is: the machine is provided with a rotating device, when the two workpieces are rotated, the lower system The bottom of the transfer device is pressed and the red part is pressed by the ultrasonic generator of the ultrasonic machine, and the upper and lower workpiece joint surfaces are refining and joining, and the upper and lower molten materials are mixed by the ultrasonic device. Drop, ® achieves the effect of increasing the tightness of the joint. [Prior Art]: ^Check, the conventional ultrasonic welding, are set as shown in Figure 1: a machine 10 has an ultrasonic machine 1 and two workpieces to be joined are placed on the table 1 The ultrasonic generator 12 of the ultrasonic machine 可1 can be lowered and raised, and when it is lowered, it is pressed against the upper workpiece, and the ultrasonic wave generated by the ultrasonic machine can melt the joint between the upper and lower workpieces 1, 2, and can be melted. The two workpieces i and 2 are integrally joined together; in the above, the following disadvantages are found: (1) The two workpieces 1 and 2 are joined by a "downward pressing" type, so that a fuse line needs to be formed. (2) The fuser line should not be too wide, that is, the area of the transfer* can be too large, otherwise the fusion will be poor, or even the fusion effect will not occur. (3) When the supersonic ship thief is used, the supersonic ship connection processing and the rotary welding process are performed, or the two processes are performed successively. SUMMARY OF THE INVENTION: Refer to Figure 2, the three 'system-ultrasonic machine n machine 1 () is equipped with a rotating device 'rotating device is set up by the base 22, the turntable 2 〇, the motor 3 〇 5 200948520 into ' The bottom of the turntable 20 is fixed to the casing 1纟, and the upper base is assembled. The base 22 is placed for the workpiece to be joined, and the bottom of the base & is coupled to the rotating shaft 31 of the motor 3. The base 22 is formed by the motor 30. And high-speed rotation, when the workpiece 2 below rotates at high speed and fix the workpiece! The contact frictional heat generation 'joining surface W is melted by heat. When welding, the upper workpiece 1 is fused by the ultrasonic generator 12 of the ultrasonic machine. At this time, the ultrasonic generator 12 generates ultrasonic waves to make the joint surface w melt. The molten materials are mixed with each other, and the molten material of the joint surface W of the motor is rapidly cooled, so that the joint faces W of the two workpieces 2 are more closely joined. [Embodiment]: As shown in Fig. 3, the turntable 2G of the present (4) can be provided with a thrust bearing 21. The base 22 can be provided with a clamp 23 for the lower workpiece 2, and a shield can be provided on the outer circumference of the turntable 20. 24 is coated with the protection turntable 20 to prevent dust from intruding into the miscellaneous bearing 21, and has the safety effect of the human being. . (4) _, effect ·· Please refer to the third, #魏接 two workpieces 2, the ultrasonic generator 12 descends against the upper workpiece, the workpiece 2 is clamped by the fixture 23 on the base 22 At this time, the motor 3 turns the shaft 31 to rotate at a constant speed, so that the material of the joint surface # is condensed by the friction heat generation, and ultrasonic vibration is generated from the ultrasonic generator 12, and the joint (4) solidifies, and the joint surface W can be improved. More tightly the effect of Weihe. In other words, this month can make the joint surfaces of the two workpieces 1 and 2 produce the function of "melting material mixing", and the upper and lower materials can be entangled and fastened together, so that the two workpieces can be better connected. Main 200948520 It can be seen from the above description that 'the invention makes the two workpieces 1 and 2 melt and join, not only the compression of the lower pressure by the rotary fusion, but also the super-coupling surface w to make the materials entangled and tight under the rotation. To 1, and efficiency, in line with the new patents, Lin Zhuzhan specializes in the close-knit function [Simplified illustration]: Figure 1 'Knowledge stereogram
