When nozzle 5717 rotates, branch plate 5714... 712 drives gear component three 5724 to rotate along the direction of gear ring 573. Since gear component three 5724 is meshed with gear ring 573, gear component three 5724 rotates on its own. Gear component three 5724 drives control rod 5723 to rotate. Control rod 5723 drives inclined plate 5721 to rotate. Inclined plate 5721 drives base block 5720 to rotate. Base block 5720 drives slider two 5714 to move left and right repeatedly. Slider two 5714 drives mounting frame 5715 to move. Mounting frame 5715 drives nozzle 5717 to vibrate left and right repeatedly, increasing the cleaning effect.
[0034] Example 2, based on Example 1, such as Figure 3 , Figure 4 , Figure 7 - Figure 9As shown, the mounting assembly 56 includes a slide groove 562, which is formed on the upper and lower sides of the rotating plate 54.

A slide rod 565 is provided on the outer side of the movable plate 564. A placement platform 566 is fixedly connected to the upper side of the slide rod 565. Electric push rods 567 are fixedly connected to both the left and right sides of the placement platform 566. A clamping block 568 is fixedly connected to the outer end of the electric push rod 567. The outer side of the slider 563 is fixedly connected to... A reciprocating rod 5612 is connected, with its left end passing through the left side of the rotating plate 54 and fixedly connected to a contact block 5613. A spring 5614 is fixedly connected between the contact block 5613 and the rotating plate 54. A contact rod 5728 is provided on the outer side of the side plate 52, with a control block 5730 fixedly connected to its outer end. The contact rod 5728 is located to the left of the contact block 5613. A reciprocating plate 5731 is fixedly connected to the left side of the control block 5730, and a spring is fixedly connected between the control block 5730 and the side plate 52. Spring 5729, bevel gear 5725 is fixedly connected to the upper end of rotating rod 578, connecting rod 5727 is rotatably connected to the inner side of fixed box 51, bevel gear 5726 is fixedly connected to the outer end of connecting rod 5727 and meshes with bevel gear 5725, bevel gear 5732 is fixedly connected to the left end of connecting rod 5727, side block 5733 is fixedly connected to the outer side of fixed box 51, rotating shaft 5734 is rotatably connected to the outer side of side block 5733, and the front end of rotating shaft 5734 is fixedly connected to bevel gear 5725. The bevel gear 5736 meshes with the shaft 5732, and the rear end of the shaft 5734 is fixedly connected to the cam 5735. Before engraving the hearing aid, the hearing aid is first placed on the placement platform 566. Then, the electric push rods 567 on both sides are controlled to drive the clamping blocks 568 to move, so that the clamping blocks 568 on both sides limit the hearing aid, which facilitates the stability of engraving. The rotation of the rotating plate 54 is controlled, the bottom hearing aid is cleaned, and the upper placement platform 566 can continue to engrave the hearing aid, which is convenient for continuous engraving and simple to operate.
[0035] When cleaning the hearing aid, the rotating rod 578 drives the first bevel gear 5725 to rotate, which in turn drives the second bevel gear 5726 to rotate. The second bevel gear 5726 then drives the connecting rod 5727 to rotate, which in turn drives the third bevel gear 5732 to rotate. The third bevel gear 5732 then drives the fourth bevel gear 5736 to rotate, which in turn drives the second rotating shaft 5734 to rotate. The second rotating shaft 5734 then drives the cam 5735 to rotate, causing the cam 5735 to move the reciprocating plate 5731 back and forth repeatedly. The reciprocating plate 5731 then moves the control block 5730, which in turn moves the contact rod 5728 back and forth repeatedly. At this time, the contact rod 5728 repeatedly... The contact block 5613 impacts the hearing aid, causing it to move left and right repeatedly under the action of the second spring 5614. The contact block 5613 drives the reciprocating rod 5612 to move, which in turn drives the slider 563 to move. The slider 563 then drives the moving plate 564 to move left and right, facilitating the control of the hearing aid's left and right movement on the placement platform 566. Simultaneously, the placement platform 566 drives the abutment rod 5611 to move left and right repeatedly. Under the action of the protrusion 561, the abutment rod 5611 drives the front block 5610 to move up and down repeatedly. The front block 5610 then drives the placement platform 566 to move up and down repeatedly, allowing impurities on the hearing aid's surface to fall off quickly due to inertia, further enhancing the cleaning effect.
[0036] Cam 5735 abuts against reciprocating plate 5731. Front block 5610 is fixedly connected to the front side of placement platform 566. A stop rod 5611 is fixedly connected to the lower side of front block 5610. Multiple protrusions 561 are fixedly connected to the outer side of rotating plate 54. The stop rod 5611 abuts against the protrusions 561. Spring 569 is fixedly connected between placement platform 566 and moving plate 564. Contact rod 5728 is not connected to contact block 5613.
[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0038] During operation, the hearing aid is first placed on the placement platform 566. Then, the electric push rod 567 drives the clamp 568 to limit the hearing aid's position. Next, the laser engraving head 4 is controlled to engrave the hearing aid. After engraving, the motor 1 55 drives the rotating plate 54 to rotate, which in turn rotates the hearing aid. Then, the air pump 576 is activated, causing multiple nozzles 5717 on the fixing tube 5716 to spray high-speed airflow onto the surface of the hearing aid to clean impurities. Simultaneously, the motor 2 575 is activated, driving the rotating rod 578 to rotate. Under the action of the gear 2 5710, gear 1 579, rotating tube 577, and connecting tube 5719, the multiple nozzles 5717 are controlled to rotate. Meanwhile, the branch plate 5712 drives the gear component 5724 to rotate. Under the action of the gear ring 573, the gear component 5724 rotates. Under the action of the control rod 5723, the inclined plate 5721 and the bottom block 5720, the slider 5714 moves left and right repeatedly, which facilitates the control of the nozzle 5717 to move left and right repeatedly, increasing the cleaning effect. At the same time, under the action of the bevel gear 5725, bevel gear 5726, connecting rod 5727, cam 5735 and reciprocating plate 5731, the contact rod 5728 is controlled to push the contact block 5613 to move left and right repeatedly, which facilitates the control of the hearing aid to move left and right. Under the action of the abutment rod 5611 and the protrusion 561, the hearing aid is controlled to move up and down repeatedly, further increasing the cleaning effect.
