Technical Field

[0001] The utility model relates to the technical field of ultrasonic processing, in particular to an ultrasonic processing fixture and an ultrasonic processing device. Background Art

[0002] In today's highly developed information society, the market for various consumer electronic products is huge, and people's requirements for the appearance personalization and diversification of products are getting higher and higher. Ordinary smart bracelets no longer have prominent selling points and functional applications. However, this type of smart bracelet adopts the human nerve induction function and is combined with the application of VR / AR technology, which will make the virtual reality technology more innovative and multifunctional.

[0003] The thickness of each human wrist is uneven and the contour difference is large. The conventional bracelet locking method is difficult to meet the needs of human nerve touch. This type of smart bracelet is made of textile materials. After obtaining the required structure by ultrasound, it is combined with the counterpart. When worn, the textile has a certain elasticity and can be stretched, so that the touch panel of the bracelet closely adheres to the human wrist, thus achieving human nerve induction control.

[0004] In the prior art, the methods and processing steps for compressing and cutting textiles by ultrasound are as follows:

[0005] a. Manually put the textile into the ultrasonic fixture, press the operation switch, and plasticize and compress the textile through the heat generated instantaneously by ultrasound, so as to reach the required thickness (0.30 - 0.40 mm). Take out the textile and put it into another ultrasonic fixture again, press the operation switch, and cut off the overflowing corners after plasticizing and compressing through the ultrasonic heat and pressure to obtain the required shape structure;

[0006] b. Thermally press and combine one side of the compressed and cut textile with the counterpart through thermosetting adhesive, and put it into the mold for injection molding and encapsulation;

[0007] c. The tensile force of the textile after plasticizing, compressing, cutting and encapsulating can reach 100 N, meeting the 40 N specification required by the design.

[0008] Among them, in ultrasonic plasticizing and compressing and ultrasonic cutting, since the ultrasonic fixtures on the ultrasonic equipment are different, it is necessary to take out the plasticized and compressed textile and put it into another ultrasonic fixture for cutting, resulting in repeated clamping of the textile, which will waste processing time, the processing efficiency is low, and the accuracy is distorted.

[0034] As Figures 1 to 5 shown, an ultrasonic processing jig provided by the present utility model includes a base 10, a lower welding head 20, and a fixture 30. The lower welding head 20 and the fixture 30 are both arranged on the base 10. The lower welding head 20 is fixedly connected to the base 10, and the fixture 30 is detachably connected to the base 10. A first positioning member 111 is provided on the base 10, and a second positioning member 311 that cooperates with the first positioning member 111 is provided on the fixture 30. The first positioning member 111 and the second positioning member 311 are jointly used for installing and positioning the fixture 30. Among them, the lower welding head 20 is fixedly connected to the base 10 by bolts; the fixture 30 can be detachably connected to the base 10 by means of magnetic attraction, clamping, etc. Of course, the fixture 30 can also be directly placed on the base 10, and the positioning effects of the first positioning member 111 and the second positioning member 311 are used to prevent the fixture 30 from moving in the horizontal direction.

[0035] Further, one of the first positioning member 111 and the second positioning member 311 is a positioning groove, and the other is a positioning post that cooperates with the positioning groove. In this embodiment, the first positioning member 111 is a positioning groove, and the second positioning member 311 is a positioning post. The positioning groove is provided on the side of the base 10 facing the fixture 30, and the positioning post is provided on the side of the fixture 30 facing the base 10. Alternatively, in other embodiments, it may also be that the first positioning member 111 is a positioning post and the second positioning member 311 is a positioning groove. Optionally, the number of the positioning grooves and the positioning posts is three and they are distributed in a right triangle, so as to play an anti-fooling role and prevent the fixture 30 from being installed in the wrong way. The opening of the positioning groove is a flared structure, and the top of the positioning post is a conical structure, so as to facilitate the installation of the fixture 30 on the base 10.

[0036] Further, a cushion block 11 is provided on the base 10. The cushion block 11 is located between the base 10 and the fixture 30. The first positioning member 111 is provided on the cushion block 11. The fixture 30 can be lifted by the cushion block 11 so that the height of the workpiece (textile) clamped on the fixture 30 can cooperate with the lower welding head 20. In this embodiment, the cushion block 11 and the base 10 are of a split structure, and the cushion block 11 is installed on the base 10 by bolts.

[0037] In this embodiment, the fixture 30 includes a bottom plate 31, a clamping plate 32 and a locking mechanism 33. The clamping plate 32 is rotatably connected to the bottom plate 31, and the locking mechanism 33 is used to control the locking state of the clamping plate 32 and the bottom plate 31. As Figure 1 shown, when the locking mechanism 33 is in the locked state, the locking mechanism 33 can prevent the clamping plate 32 and the bottom plate 31 from rotating, so as to avoid the position of the textile on the fixture 30 from moving during the processing or transfer of the textile, resulting in a reduction in processing accuracy; as Figure 2 shown, when the locking mechanism 33 is in the unlocked state, the clamping plate 32 can rotate with the bottom plate 31, so that the clamping plate 32 and the bottom plate 31 can be opened to facilitate the clamping or removal of the textile.

[0038] Further, the locking mechanism 33 includes a fixed block 331, a locking block 332, and a locking plate 333. The locking plate 333 is rotatably connected to the fixed block 331. The rotation axis of the locking plate 333 is perpendicular to the rotation axis of the clamping plate 32. A locking groove 332a that cooperates with the locking plate 333 is provided on the locking block 332. Optionally, an avoidance groove 331a is provided on the fixed block 331, and the avoidance groove 331a cooperates with the locking block 332. When the locking mechanism 33 is in the locked state, the locking block 332 is inserted into the avoidance groove 331a, and the locking plate 333 is snapped into the locking groove 332a. During the locking process of the locking mechanism 33, first, the clamping plate 32 and the bottom plate 31 are closed, so that the locking block 332 is inserted into the avoidance groove 331a, and then the locking plate 333 is snapped into the locking groove 332a. In this embodiment, the fixed block 331 is fixed to the clamping plate 32, and the locking block 332 is fixed to the bottom plate 31. Of course, in other embodiments, the fixed block 331 can also be fixed to the bottom plate 31, and the locking block 332 can be fixed to the clamping plate 32.

[0039] Further, a first receiving groove 312 is provided on the bottom plate 31. The first receiving groove 312 is used to receive the workpiece. The structure of the first receiving groove 312 matches that of the textile. The width and depth of the first receiving groove 312 can be set according to the width and thickness of the textile. Optionally, an anti-slip structure 312a can also be provided in the first receiving groove 312. The anti-slip structure 312a can be an anti-slip groove or anti-slip ribs, so as to increase the clamping effect of the fixture 30 on the textile.

[0040] In this embodiment, the ultrasonic processing fixture includes a support seat 40 installed on the base 10. The support seat 40 can be installed on the base 10 by bolts. The support seat 40 is located at one end of the fixture 30 away from the lower welding head 20. A second receiving groove 41 is provided on the support seat 40.

The width and depth of the second receiving groove 41 can be set according to the width and thickness of the textile.

[0041] In this embodiment, the lower welding head 20 is a compression welding head 21 or a cutting welding head 22, that is, there is one lower welding head 20 in an ultrasonic processing fixture. The lower welding head 20 can be a compression welding head 21 or a cutting welding head 22. Among them, the upper surface of the compression welding head 21 is a plane, and the upper surface of the cutting welding head 22 is provided with a profiling groove 221. The shape of the profiling groove 221 is set according to the shape that the workpiece needs to be cut.
