In the modern trend, clothing and clothing made of artificial gems or metal sheets fixed in different patterns on various textile fabrics are popular, and are more and more popular among consumers, especially young people.

Figures 6 and 7 show vertical cross-sectional views of so-called "artificial gemstones" and "metal sheets". The shapes of artificial gemstones and metal sheets are round, but the bottom surface of the artificial gemstones is flat and the top is cut like a diamond. In multiple faces. The metal piece is shaped like a spherical cap, and its bottom surface is also concave. This book refers to the fascinating gems and metal sheets collectively referred to as decorative pieces.

The traditional method of welding the decorative sheet to the fabric is done manually, including the following steps: using the decorative sheet to form the desired pattern on the fabric; covering the pattern with the film; ironing the film and pattern with the ironing board, The decorative sheet is heated and pressurized; when the film is removed, a desired decorative sheet pattern is formed on the processed cloth.

As shown in FIG. 1, FIG. 2 and FIG. 2A, the automatic ultrasonic welding machine of the present invention is controlled by a control part and Mechanical part. The control section includes the controller 1 and the control panel 2. The mechanical parts can be divided into a feeding unit, an ultrasonic processing unit, a fixing unit and a driving unit according to different functions. The feeding unit comprises a first beam 3, a feeding device F having a feeding box 4, a feed carousel 5 and a suction head 6, a feed drive 7 for driving the feeding device and a vacuum source 8. The fixing unit includes a work table 9 and a cloth frame 10. The ultrasonic machining unit includes a second beam 11, an ultrasonic device U having an ultrasonic generator 12 and an ultrasonic horn 13. The drive unit 14 includes a first beam drive and a second beam drive (both housed in the same control box, shown in the form of drive unit 14 in the figure).

The fabric to be processed is stretched with a cloth holder 10 and fixed to the table 9. The cloth holder 10 and the table 9 are hollow in the portion corresponding to the pattern to be formed, and the operator inputs the parameters and special instructions of the pattern to the controller 1 from the control panel 2. The controller 1 is equipped with control software, and the control software forms a control program according to the parameters and instructions of the pattern, and the controller 1 thereby sends a corresponding control signal to the mechanical part, thereby automatically completing the machining process.

The feeding device F is mounted on the first beam 3 above the table 9. The feeding box 4 is connected to the feeding turntable 5, and the feeding turntable 5 is disposed in the vicinity of the suction head 6. When the decorative sheet in the feeding turntable 5 is used up, the feeding box 4 automatically supplies the decorative sheet to the feeding turntable 5. The feed driver 7 drives the tip 6 according to the signal of the controller to complete the action of sucking the decorative sheet. The vacuum source 8 provides a vacuum to the tip 6 during the process of drawing the decorative sheet from the tip to solder it to the desired location.

The ultrasonic device U is mounted on the second beam 11 below the table 9. When performing the soldering operation, the tips of the ultrasonic horn and the feeding device should be aligned.

The operation of the automatic ultrasonic welding machine of the present invention will now be described.

After the control panel 1 inputs the pattern to be processed, the controller 1 issues an instruction according to the generated control program, and the first and second beam drivers respectively drive the first beam 3 and the second beam 11 to drive the feeding device F and the ultrasonic device U to reach the corresponding pattern. Starting position of the starting point At this time, the suction head 6 and the ultrasonic horn 13 are aligned with each other. The feed driver receives the signal from the controller 1 and drives the tip 6 to move to align the decorative sheet in the feed carousel 5, at which time the vacuum source 8 applies a vacuum to the tip 6 to attract the decorative sheet. The tip 6 is then driven back to its original starting position.

The first beam drive drives the first beam 3 to move downward, while the second beam driver drives the second beam 11 to move upward. When the suction head 6 of the suction decorative sheet and the ultrasonic horn 13 are pressed against each other via the cloth, the pressure between the two increases, and a signal is sent to the ultrasonic generator 12 to operate the ultrasonic generator 12 to emit ultrasonic waves. The head 13 pressurizes and heats the decorative sheet to weld it to the cloth. After a predetermined period of time, the ultrasonic generator 12 stops working. Vacuum source 8 No more vacuum is provided to the tip 6. The first and second beam drives respectively drive the first and second beams 3 and 11 to move up and down, leaving the cloth. The decorative sheet is firmly welded to the fabric. The first and second beams 3 and 11 then drive the tip 6 and the ultrasonic horn 13 to translate again to the next bonding position. Repeat the above work process to complete a pattern.

In the embodiment shown in Fig. 1, a plurality of feeding devices are mounted on the first beam 3, and a plurality of ultrasonic devices u are mounted on the second beam 11. Both - corresponding. A corresponding set of feeding devices F and an ultrasonic device U cooperate to complete a pattern. When the first and second beams 3 and 11 drive the plurality of feeding devices F and the ultrasonic device U to operate synchronously, a plurality of identical patterns can be simultaneously completed.

In another embodiment of the invention shown in Fig. 3, the other constructions are the same as the embodiment shown in Fig. 1, with the difference that each of the two adjacent feeding devices F and F' on the first beam 3 corresponds to one The ultrasonic device U on the second beam 11. Decorative sheets of different colors are stored in the feeding boxes of the feeding devices F and F', respectively. The controller selects a corresponding feeding device to work with the ultrasonic device at each soldering position according to the requirements of the processing pattern. Therefore, the decorative sheet pattern formed by this embodiment is more varied than the embodiment of Fig. 1.

Of course, in the embodiment of Fig. 3, it is also possible to select an ultrasonic device to cooperate with three or more feeding devices to achieve more variations of the processing pattern.

In another preferred embodiment, not shown, although the feeding device F corresponds to the ultrasonic device U, each feeding device includes a plurality of feeding boxes and associated feeding turntables, respectively, which respectively hold different decorative pieces. . At each soldering location, the controller signals the feed drive according to the requirements of the pattern, and the drive tip draws the desired trim from the corresponding feed carousel. Other constructions and working steps of the automatic soldering machine are the same as in the embodiment of Fig. 1.

In the conventional ultrasonic welding machine, the top surface of the welding head is flat. When such a welding head is welded to a metal piece, since the contact area with the metal piece is too small to be effectively pressurized, the metal piece cannot be firmly welded to the cloth. In order to solve this problem, the welding head of the present invention has a replaceable head. The replaceable head can be mounted on the welding head in the form of a nut. When processing an artificial gemstone, a head having a flat top as shown in Fig. 4 is used. When processing a metal sheet, an arc-shaped head having a top surface complementary to the bottom surface of the metal sheet as shown in Fig. 5 can be used. Thus, the automatic ultrasonic welding machine of the present invention can process various types of decorative sheets of the prior art.

While the present invention has been described with respect to the preferred embodiments, the various modifications and variations of the invention may be made without departing from the spirit and scope of the invention.
