[0026] See also Figure 1-7 As shown, an embodiment of the present invention provides a disassembly device for an ultrasonic transducer, comprising a frame 4.

[0027] See also Figure 1 、 3 As shown in Figures 6 and 7, a horn fixing seat 5 is provided on the work surface of the frame 4. The horn fixing seat 5 is used to vertically fix the screw 31 of the horn 3. The horn fixing seat 5 includes a seat body 51 and a latch 52. A groove 511 is formed on the upper part of the seat body 51 to match the shape of the exposed side of the horn, and an opening 512 is formed at the bottom of the groove 511 for the screw 31 of the horn 3 to be inserted. A slot 513 for the latch to be inserted is formed on the side of the seat body 51, and the slot 513 and the opening 512 intersect. A fork head is formed on the latch 52 to match the flat head of the screw 41 of the horn 3.

[0028] See also Figure 1-5 As shown, the frame 4 is also equipped with a Y-axis linear drive module 6, which includes a cylinder 61, a guide rail 62, a slider 63 movably mounted on the guide rail 62, and a connecting plate 64 fixedly connected to the slider 63. The guide rail 62 is vertically mounted on the frame 4, and the cylinder 61 is hinged to the frame 4 at one end and to the connecting plate 64 at the other end.

[0029] The connecting plate 6 is fixedly connected to the lifting platform 7. A servo motor 71 is mounted on the lifting platform 7. A reducer 72 is mounted on the output shaft of the servo motor 71. The output end of the reducer 72 is connected to an air slip ring 73, which is connected to a pneumatic chuck 74 via a self-contracting mounting seat 75. Unlike conventional pneumatic slip rings and chucks, the self-contracting mounting seat 75 in this embodiment enables the pneumatic chuck 74 to automatically approach the air slip ring 73 when pressure is applied. The specific structure is as follows:

[0030] The air slip ring 73 includes a stator 731 and a rotor 732 . The stator 731 is provided with a first air hole in the circumference, and the rotor 732 is provided with a second air hole in the circumference. The first air hole and the second air hole are connected through an internal air path of the air slip ring.

[0031] The stator 731 is directly or indirectly fixedly connected to the lifting platform 7. In a preferred embodiment, the stator 731 is connected to the housing of the reducer 72 via four bolts.

[0032] One end of the rotor 732 is provided with a connecting shaft, which is in transmission connection with the reducer 72. The other end of the rotor 732 opposite to the connecting shaft is provided with a sliding groove 7321 coaxial with the connecting shaft.

[0033] The self-retracting mounting seat 75 comprises a seat body 751 and a transmission shaft 752 vertically disposed in the middle of the seat body 751. The transmission shaft 752 is shaped to match the shape of the slide groove 7321 and is inserted into the slide groove 7321, allowing the self-retracting mounting seat 75 to rotate with the rotor 732 and slide axially relative to the rotor 732. To achieve the above purpose, the transmission shaft 752 is square in shape in this embodiment. Obviously, those skilled in the art will understand that, provided that structural strength is met, other shafts with non-circular cross-sections, such as spline shafts, and hole-matching structures can also achieve the above effect.

[0034] Between the base 751 and the rotor 732, there are provided an elastic member that forces the two to move apart, as well as a connecting member that prevents the two from separating. In this embodiment, the rotor 732 has a flange with a plurality of through-holes evenly spaced therein. A guide rod 76 is movably sleeved within the through-holes. One end of the guide rod 76 has a nut larger than the through-hole, and the other end is vertically threadedly connected to the base 751. A spring is sleeved on the guide rod 76, with its ends respectively abutting the flanges of the base 751 and the rotor 732. The guide rod 76 prevents the two from separating, while the spring on the guide rod 76 forces the two to move apart.

[0035] A pneumatic chuck 74 is fixed to a self-contracting mounting base 75. It is equipped with a clamping jaw 741 that matches the shape of the housing. Clamping jaw 741 is located directly above the horn mounting base 5. A third air hole is provided on the peripheral wall of the pneumatic chuck 74. The third air hole and the second air hole are connected in a one-to-one correspondence via an air pipe. The above-described air circuit structure is conventional in the art and will not be further described here.

[0036] Thus, the ultrasonic transducer's horn is clamped by the horn holder 5, while the Y-axis linear drive module 6 drives the lifting platform 7 up and down until the pneumatic chuck 74 descends to the outside of the ultrasonic transducer housing and clamps it. The servo motor 71 on the lifting platform 7 then drives the pneumatic chuck 74 to rotate via the reducer 72. The clamping claws on the pneumatic chuck rotate the ultrasonic transducer housing, and the rotation of the ultrasonic transducer housing is accompanied by an upward movement. The self-retracting mounting seat 75 automatically retracts to accommodate the upward movement of the ultrasonic transducer housing until the ultrasonic transducer housing is rotated away from the horn, thereby completing the removal of the transducer housing.

[0037] Compared with the prior art, the present invention has the following advantages: the device can be used for automated production, improve efficiency, reduce labor costs, and is safer to operate. In addition, the device has the advantages of simple structure, easy and convenient operation, and will not damage the transducer.

[0038] The above embodiments describe the utility model intention and implementation methods of the utility model in detail, but a person skilled in the art in the art will understand that the above embodiment of the utility model is only one of the preferred embodiments of the utility model. Due to space limitations, not all implementation methods can be listed here one by one. Any implementation that can embody the technical solution of the claims of the utility model is within the scope of protection of the utility model.

[0039] It should be noted that the above content is a further detailed description of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation methods of the present invention are limited to these. Under the guidance of the above embodiments, those skilled in the art can make various improvements and modifications on the basis of the above embodiments, and these improvements or modifications fall within the scope of protection of the present invention.
