[0033] A brazing tooling method for a guided wave transmission ultrasonic elliptical vibration cutting device,

[0034] Step 1: Inspection of welding and welding quality between the X-direction transducer 2, the Y-direction transducer 1 and the waveguide 5;

[0035] Step 2: Inspection of welding and welding quality between the waveguide strip and the tool head 3 in the X direction;

[0036] Step 3: Inspection of welding and welding quality between the waveguide tape and the tool head 3 in the Y direction.

[0037] Further,

[0038] In step 1, the waveguide strip 5 is composed of several long thin sheets, which need to be fixed before welding to ensure that the end surfaces of the several long thin sheets are flush;

[0039] First, place the X-direction transducer 2 or the Y-direction transducer 1 into the circular groove of the tooling body 10 that matches the X-direction transducer 2 or the Y-direction transducer 1. Then, use the baffle 11 to fix the X-direction transducer 2 or the Y-direction transducer 1 to the tooling body 10. Finally, put on the cavity ring 21. The cavity ring 21 is put on the end of the X-direction transducer 2 or the Y-direction transducer 1, so that the welding end surface of the X-direction transducer 2 or the Y-direction transducer 1 forms a cavity to receive the molten solder during welding. After welding is completed, remove the cavity ring 21.

[0040] When the waveguide tape 5 is fixed on the waveguide tape fixing seat 12, the waveguide tape spacers 20 are used to separate the waveguide tapes 5. The waveguide tape pressing block 19 presses the waveguide tape 5 and the waveguide tape spacers 20 to ensure the size of the sheet spacing.

[0041] The position of the waveguide belt fixing seat 12 on the guide rail 13 is adjusted by the driving mechanism, thereby adjusting the distance between the waveguide belt 5 and the X-direction transducer 2 or the Y-direction transducer 1 to ensure the flow of solder during welding;

[0042] In the tensile test of the welding strength after the waveguide belt 5 is welded to the X-direction transducer 2 or the Y-direction transducer 1, the screw 16 is subjected to an upward force through the driving mechanism. The X-direction transducer 2 or the Y-direction transducer 1 cannot move upward due to the obstruction of the baffle, thereby performing a tensile test on the welding part, and the pressure sensor monitors the tension value in real time.

[0043] Further,

[0044] In step 2, the tool head 3 is fixed to the tool body 10 by bolts, and the first cavity block 22 is fixed on the tool body 10 to form a cavity with the X-direction welding surface of the tool head to hold the molten solder during welding; when welding the tool head 3X direction to the other end face of the waveguide belt 5, the whole is flipped 90° so that the X-direction welding surface of the tool head faces upward to hold the solder during welding, and the remaining actions are the same as step 1.

[0045] Further,

[0046] In step 3, the tool head 3 is fixed to the tool body 10 by bolts, and the second cavity block 23 is fixed on the tool body to form a chamber with the Y-direction welding surface of the tool head to hold the molten solder during welding; when welding the tool head 3 in the Y direction to the other end face of the waveguide belt 5, the whole is flipped back to the state of step 1 so that the Y-direction welding surface of the tool head faces upward to hold the solder during welding, and the rest of the actions are the same as step 1.

[0047] In summary, the beneficial technical effects of the present invention are:

[0048] The present invention adopts an adjustable waveguide position in the brazing connection between the two ends of the waveguide and the tool head, X-direction transducer 2 or Y-direction transducer 1 respectively. Adjusting the relative position between the waveguide 5 and the X-direction transducer 2 or Y-direction transducer 1 and the tool head 3 before welding is beneficial to the flow of solder during welding and helps to improve the welding quality. In detecting the welding quality after welding, the present invention combines a pressure sensor to perform a tensile test between the welded waveguide and the X-direction transducer 2 or Y-direction transducer 1 and the tool head. When the value detected by the pressure sensor during stretching reaches a certain threshold and no cracks or other damage occur in the welding part between the waveguide and the X-direction transducer 2 or Y-direction transducer 1 and the tool head, it is considered that the welding strength is sufficient. CCD is used to identify the weld morphology before and after the tensile test to detect whether there are pores, microcracks and other weld morphologies that affect the sound transmission efficiency.

[0049] The present invention aims to provide the design of assembly auxiliary tooling and the detection of its quality after assembly for the production and assembly process of an ultrasonic elliptical vibration cutting device based on guided wave transmission. The assembly of the device mainly involves the brazing connection between the waveguide belt and the tool head, the X-direction transducer 2 or the Y-direction transducer 1. During the brazing process, it is necessary to fix the relative position between the waveguide belt and the tool head, the X-direction transducer 2 or the Y-direction transducer 1 before brazing, and to detect the welding quality after brazing to ensure a good connection between the waveguide belt and the X-direction transducer 2 or the Y-direction transducer 1 and the tool head and the overall electroacoustic efficiency. The present invention adopts a form in which the position of the waveguide belt is adjustable, and the relative position between the waveguide belt and the X-direction transducer 2 or the Y-direction transducer 1 and the tool head can be adjusted before welding, which is conducive to the flow of the solder, thereby improving the welding quality. At the same time, the present invention combines a pressure sensor to perform a tensile test between the welded waveguide belt and the X-direction transducer 2 or the Y-direction transducer 1 and the tool head to detect the welding strength and weld morphology. The weld strength is considered sufficient when the pressure sensor reading reaches a certain threshold during stretching and no cracks or other damage occur in the welds between the waveguide ribbon and the X-direction transducer 2, the Y-direction transducer 1, or the tool head. Furthermore, a CCD is used to identify weld morphology before and after the tensile test to detect any weld features that could affect sound transmission efficiency, such as pores and microcracks.

DETAILED DESCRIPTION

[0062] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

For example, they may refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0065] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0066] like Figure 1 As shown, the assembly of the dual-excitation ultrasonic elliptical vibration cutting device based on guided wave transmission mainly involves brazing the two ends of the waveguide belt 5 with the tool head 3 and the transducer (X-direction transducer 2, Y-direction transducer 1) respectively. During the brazing process, the relative positions of the waveguide belt 5 and the tool head 3, the X-direction transducer 2, and the Y-direction transducer 1 need to be fixed before brazing. After brazing, the welding quality needs to be tested, including the welding strength, weld morphology, etc., to ensure a good connection between the waveguide belt and the X-direction transducer or the Y-direction transducer and the tool head, and to ensure the overall electroacoustic efficiency. The present invention is also applicable to the assembly quality of a single-excitation elliptical vibration cutting device and its quality testing after assembly.

[0067] Brazing steps are:

[0068] Step 1: Inspection of welding and welding quality between the X-direction transducer 2, the Y-direction transducer 1 and the waveguide;

[0069] Step 2: Inspection of welding and welding quality between the waveguide strip and the tool head 3 in the X direction;

[0070] Step 3: Inspection of welding and welding quality between the waveguide tape and the tool head 3 in the Y direction.

[0071] The present invention adopts an adjustable waveguide position in the brazing connection between the two ends of the waveguide and the tool head, X-direction transducer 2 or Y-direction transducer 1 respectively. Adjusting the relative position between the waveguide 5 and the X-direction transducer 2 or Y-direction transducer 1 and the tool head 3 before welding is beneficial to the flow of solder during welding and helps to improve the welding quality. In detecting the welding quality after welding, the present invention combines a pressure sensor to perform a tensile test between the welded waveguide and the X-direction transducer 2 or Y-direction transducer 1 and the tool head. When the value detected by the pressure sensor during stretching reaches a certain threshold and no cracks or other damage occur in the welding part between the waveguide and the X-direction transducer 2 or Y-direction transducer 1 and the tool head, it is considered that the welding strength is sufficient. CCD is used to identify the weld morphology before and after the tensile test to detect whether there are pores, microcracks and other weld morphologies that affect the sound transmission efficiency.

[0072] The following is an introduction to the structure according to the welding steps:

[0073] Step 1. Inspection of welding and welding quality between the X-direction transducer 2, the Y-direction transducer 1 and the waveguide tape 5.

[0074] like Figure 1 As shown, the X-direction transducer 2 or the Y-direction transducer 1 is the same, as Figure 2 As shown, the welding requirements between the X-direction transducer 2 or the Y-direction transducer 1 and one end of the waveguide tape 5 are met.

[0075] The waveguide 5 is composed of several long thin sheets, which need to be fixed before welding to ensure that the end faces of the several long thin sheets are flush. The welding of the above-mentioned X-direction transducer 2 or Y-direction transducer 1 and the waveguide 5 requires the design of its welding tooling, such as Figure 3 As shown, the structure for realizing welding and welding quality detection between the X-direction transducer 2 or the Y-direction transducer 1 and the waveguide belt includes: 6-CCD, 7-CCD seat, 8-CCD support frame, 9-base, 10-tooling body, 11-baffle, 12-waveguide belt fixing seat, 13-guide rail, 14-pressure sensor, 15-horizontal scale, 16-screw, 17-driven gear, 18-connecting block, 19-waveguide belt pressure block, 20-waveguide belt partition, 21-cavity ring, 22-first cavity ring, 23-second cavity ring.

[0076] The CCD is fixed on a CCD seat, and the CCD seat is fixed on a CCD support frame by bolts. The CCD support frame is as follows Figure 4As shown, the CCD holder is strip-shaped and has slots cut into it. The CCD holder is hinged to the base, allowing the holder to be fixed relative to the base by tightening the bolts and rotating relative to the base by loosening the bolts. Therefore, the position of the CCD can be adjusted by adjusting the relative positions of the CCD holder and the holder, and the holder and the base, enabling different workstations to share a single CCD for welding quality inspection.

[0077] When the X-direction transducer 2 or the Y-direction transducer 1 is welded to the waveguide tape 5, Figure 5 As shown, the X-direction transducer 2 or the Y-direction transducer 1 is first placed in the circular groove of the tooling body 10 that matches the X-direction transducer 2 or the Y-direction transducer 1. The X-direction transducer 2 or the Y-direction transducer 1 is then fixed to the tooling body 10 using the baffle 11. Finally, the cavity ring 21 is put on (the cavity ring 21 is put on the end of the X-direction transducer 2 or the Y-direction transducer 1), so that a cavity is formed on the welding end surface of the X-direction transducer 2 or the Y-direction transducer 1 to receive the molten solder during welding. The cavity ring 21 is removed after welding is completed.

[0078] The fixing of the plurality of waveguide strips 5 is as follows Figure 6 As shown, since the size of the sheet spacing must be ensured after the waveguide tape 5 is welded, when the waveguide tape 5 is fixed on the waveguide tape fixing seat 12, a waveguide tape partition 20 is used to separate several waveguide tapes 5, and the waveguide tape pressing block 19 is used to press the waveguide tape 5 and the waveguide tape partition 20 to ensure the size of the sheet spacing.

[0079] like Figure 3 As shown, the guide rail 13 passes through the waveguide belt fixing base 12 and the horizontal scale 15, and the waveguide belt fixing base 12 can move relative to the guide rail 13. The horizontal scale 15 has a threaded hole drilled on the surface parallel to the axis of the guide rail 13, and the horizontal scale is fixed to the guide rail by screwing in a set screw. The screw 16 passes through the horizontal scale 15 and is fixedly connected to the connecting block 18. The other end of the connecting block 18 is connected to one end of the pressure sensor 14, and the other end of the pressure sensor 14 is connected to the waveguide belt fixing base 12. The driven gear 17 is screwed into the screw 16 and placed above the horizontal scale 15. Therefore, by rotating the driven gear 17, the position of the waveguide belt fixing base 12 on the guide rail 13 can be adjusted, thereby adjusting the distance between the waveguide belt 5 and the X-direction transducer 2 or the Y-direction transducer 1, ensuring the flow of solder during welding and ensuring welding quality.

[0080] The tensile test of the welding strength of the waveguide 5 after welding with the X-direction transducer 2 or the Y-direction transducer 1 is carried out, that is, the driven gear 17 is rotated to apply an upward force to the screw 16. The X-direction transducer 2 or the Y-direction transducer 1 cannot move upward due to the obstruction of the baffle, thereby performing a tensile test on the welding part, and the pressure sensor monitors the tensile force value in real time. The structure after welding the X-direction transducer 2 or the Y-direction transducer 1 with the waveguide is as follows Figure 7 shown.

[0081] Step 2. Inspection of the welding and welding quality between the X-direction waveguide ribbon and the tool head.

[0082] like Figure 8 As shown, the tool head 3 is fixed to the tool body 10 by bolts, and the first cavity block 22 is fixed to the tool body 10 to form a cavity with the X-direction welding surface of the tool head to receive the molten solder during welding.

[0083] like Figure 9 As shown, when welding the tool head in the X direction to the other end surface of the waveguide belt 5, the entire tool head is flipped 90 degrees so that the welding surface in the X direction of the tool head faces upward to facilitate receiving the solder during welding. The remaining actions are the same as step 1.

[0084] The tensile test of the welding strength after the tool head X direction and the waveguide belt are welded is the same as step 1. The CCD is used to detect the weld morphology after the tool head X direction and the waveguide belt are welded, that is, the CCD position is adjusted to align the visual area with the weld after the tool head X direction and the waveguide belt are welded for detection. The structure after the tool head X direction and the waveguide belt with X direction transducer 2 or Y direction transducer 1 are welded is as follows Figure 10 shown.

[0085] Step 3. Inspect the welding and welding quality between the Y-direction waveguide ribbon and the tool head.

[0086] In step 2, the tool head and the tool body have been fixed by bolts, and the second cavity block 23 is fixed on the tool body and forms a cavity with the Y-direction welding surface of the tool head to receive the molten solder during welding. Figure 11 As shown, when welding the tool head in the Y direction to the other end face of the waveguide, flip the whole thing back to the state of step 1 so that the welding surface of the tool head in the Y direction faces upwards to receive the solder during welding. The rest of the actions are the same as step 1.

[0087] The tensile test of the welding strength after the tool head is welded to the waveguide in the Y direction is the same as step 1.

[0088] The CCD is used to detect the weld shape after the tool head Y direction and the waveguide are welded, that is, the CCD position is adjusted to align the visual area with the weld seam after the tool head Y direction and the waveguide are welded for detection. The structure after the tool head Y direction and the waveguide with the X-direction transducer 2 or the Y-direction transducer 1 are welded is as follows Figure 1 shown.

[0089] The present invention aims to provide the design of assembly auxiliary tooling and the detection of its quality after assembly for the production and assembly process of an ultrasonic elliptical vibration cutting device based on guided wave transmission. The assembly of the device mainly involves the brazing connection between the waveguide belt and the tool head, the X-direction transducer 2 or the Y-direction transducer 1. During the brazing process, it is necessary to fix the relative position between the waveguide belt and the tool head, the X-direction transducer 2 or the Y-direction transducer 1 before brazing, and to detect the welding quality after brazing to ensure a good connection between the waveguide belt and the X-direction transducer 2 or the Y-direction transducer 1 and the tool head and the overall electroacoustic efficiency. The present invention adopts a form in which the position of the waveguide belt is adjustable, and the relative position between the waveguide belt and the X-direction transducer 2 or the Y-direction transducer 1 and the tool head can be adjusted before welding, which is conducive to the flow of the solder, thereby improving the welding quality. At the same time, the present invention combines a pressure sensor to perform a tensile test between the welded waveguide belt and the X-direction transducer 2 or the Y-direction transducer 1 and the tool head to detect the welding strength and weld morphology. The weld strength is considered sufficient when the pressure sensor reading reaches a certain threshold during stretching and no cracks or other damage occur in the welds between the waveguide ribbon and the X-direction transducer 2, the Y-direction transducer 1, or the tool head. Furthermore, a CCD is used to identify weld morphology before and after the tensile test to detect any weld features that could affect sound transmission efficiency, such as pores and microcracks.

[0090] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.

A method for using the brazing fixture system for the guided wave transmission ultrasonic elliptical vibration cutting device according to claim 1 or 2, characterized in that: Step 1: Inspection of welding and welding quality between the X-direction transducer, the Y-direction transducer and the waveguide; Step 2: Inspection of welding and welding quality between the waveguide strip and the tool head in the X direction; Step 3: Inspection of welding and welding quality between the waveguide tape and the tool head in the Y direction.

4. The method according to claim 3, wherein: In step 1, The waveguide strip is composed of several long thin sheets, which need to be fixed before welding to ensure that the end surfaces of the several long thin sheets are flush; The X-direction transducer and the Y-direction transducer are identical. When the X-direction transducer and the Y-direction transducer are respectively welded to the waveguide tape, the X-direction transducer or the Y-direction transducer is first placed in a circular groove of the tooling body that matches the X-direction transducer or the Y-direction transducer. The X-direction transducer or the Y-direction transducer is then fixed to the tooling body using a baffle. Finally, a cavity ring is put on the tooling body. The cavity ring is put on the end of the X-direction transducer or the Y-direction transducer so that a cavity is formed on the welding end surface of the X-direction transducer or the Y-direction transducer to receive the molten solder during welding. The cavity ring is removed after welding is completed. When the waveguide tape is fixed on the waveguide tape fixing seat, a waveguide tape partition is used to separate the waveguide tapes, and a waveguide tape pressing block is used to press the waveguide tape and the waveguide tape partition to ensure the size of the sheet spacing; The position of the waveguide belt fixing seat on the guide rail is adjusted by the driving mechanism, thereby adjusting the distance between the waveguide belt and the X-direction transducer or the Y-direction transducer to ensure the flow of solder during welding; The tensile strength test of the weld between the waveguide ribbon and the X-direction transducer or Y-direction transducer is performed by applying an upward force to the screw through the driving mechanism. The X-direction transducer or Y-direction transducer cannot move upward due to the obstruction of the baffle, thereby performing a tensile test on the welded part. The pressure sensor monitors the tensile force value in real time.

5. The method according to claim 4, characterized in that: In step 2, The tool head is fixed to the tool body by bolts. The first cavity block is fixed to the tool body and forms a cavity with the X-direction welding surface of the tool head to receive the molten solder during welding. When welding the tool head in the X direction to the other end of the waveguide, flip the tool head 90° so that the welding surface in the X direction faces upward to facilitate receiving the solder during welding. The rest of the actions are the same as step 1.

6. The method according to claim 5, characterized in that: In step 3, The tool head is fixed to the tool body by bolts. The second cavity block is fixed to the tool body and forms a cavity with the Y-direction welding surface of the tool head to receive the molten solder during welding. When welding the tool head in the Y direction to the other end of the waveguide, flip the entire tool back to the state of step 1 so that the welding surface of the tool head in the Y direction faces upward to facilitate receiving the solder during welding. The remaining actions are the same as step 1.
