[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Given the limitations of current technologies in creating custom-patterned openings in components, the low efficiency of these openings, and the resulting dust and debris pollution, this embodiment provides an opening structure for a speaker assembly component. Please refer to... Figures 1-5 This embodiment provides a speaker assembly component opening structure that can open holes in special patterns, improving opening efficiency and reducing dust pollution. The speaker assembly component opening structure includes support legs 2 installed at the four corners of the bottom of a processing table 1. The processing table 1 is equipped with an opening mechanism 3 for opening irregularly shaped holes in the speaker assembly component. The opening mechanism 3 performs various irregular hole opening operations on the speaker assembly component, and the opening is performed using a laser hole opener 37, avoiding dust pollution caused by traditional opening equipment and improving opening efficiency.

[0032] Because existing technologies struggle to create holes with special patterns on components, and the drilling efficiency is low, accompanied by a large amount of dust and debris that pollutes the working environment, this device is equipped with a drilling mechanism 3. The drilling mechanism 3 includes movable guide rails 31 installed on the front and rear sides of the processing table 1. Movable cable chains 32 are installed within guide grooves on the movable guide rails 31, and a transverse guide rail platform 33 is installed between the ends of the two movable cable chains 32. A transverse cable chain 34 is installed within guide grooves on the transverse guide rail platform 33, and a lifting cable chain is installed at the end of the transverse cable chain 34. 35, and the lifting cable chain 35 is equipped with a mounting plate 36 on its side, on which a laser hole opener 37 is mounted. The transverse guide rail 33 is equipped with a limiting component 38 to help stabilize the movement of the laser hole opener 37. The laser hole opener 37 is moved left and right by the moving cable chain 32, and moved back and forth by the transverse cable chain 34, and moved up and down by the lifting cable chain 35, so as to adjust according to the components of different thicknesses, thereby realizing the opening of irregular holes in the components without the problem of dust pollution.

[0033] To improve the stability of the laser hole opener 37, the device is also equipped with a limiting component 38. The limiting component 38 includes a T-shaped guide rail 381 mounted on the transverse guide rail 33, and a slide table 382 slidably connected to the T-shaped guide rail 381. A connecting plate 383 is mounted on the side of the slide table 382, ​​and a second T-shaped guide rail 384 is mounted on the connecting plate 383. A T-shaped groove adapted to the second T-shaped guide rail 384 is provided on the mounting plate 36. The slide table 382 is equipped with a heat dissipation component 39 to cool down the high temperature generated by the operation of the laser hole opener 37 and a purification component 310 to purify the harmful gases generated during hole opening. When the transverse drag chain 34 moves the laser hole opener 37 back and forth, it moves the slide table 382 back and forth along the T-shaped guide rail 381. When the laser hole opener 37 moves up and down, the mounting plate 36 moves on the second T-shaped guide rail 384, thereby improving the stability of the laser hole opener 37 during hole opening.

[0034] To prevent residual debris from remaining on the processing table 1 after drilling and affecting subsequent drilling processes, the device has a chip collection groove on the top of the processing table 1, and a conical collecting plate 41 is installed at the bottom of the processing table 1. A waste discharge pipe 42 is installed at the bottom of the collecting plate 41. After drilling, the debris falls directly into the collecting plate 41 through the chip collection groove. The collecting plate 41 is conical, thus guiding the debris into the waste discharge pipe 42 for discharge.

[0035] Example 2

[0036] Because the laser hole opener 37 generates a large amount of heat during operation, in order to avoid overheating and overload of the laser hole opener 37, based on Embodiment 1, as follows: Figures 1-5 As shown, the device is also equipped with a heat dissipation assembly 39, which includes a liquid storage box 391 installed on the top of the slide 382, ​​and a micro pump 392 installed on the bottom left side of the liquid storage box 391. The liquid outlet of the micro pump 392 is equipped with a liquid injection pipe 393, and a serpentine heat exchange pipe 394 is installed around the laser hole opener 37 at the end of the liquid injection pipe 393. The top end of the serpentine heat exchange pipe 394 is equipped with a return pipe 395 extending into the liquid storage box 391.

[0037] Both the injection pipe 393 and the return pipe 395 are foldable and telescopic high-temperature resistant rubber hoses. A heat sink 396 is installed on the left side of the liquid storage box 391 to cool the return coolant. The micro pump 392 is started to pump the coolant in the liquid storage box 391 into the injection pipe 393 and then into the serpentine heat exchange pipe 394, thereby cooling the laser aperture 37. The heat exchanged liquid, after being heated, flows back into the liquid storage box 391 through the return pipe 395, and works with the heat sink 396 to cool the high-temperature heat exchanged liquid, thereby achieving circulating heat exchange and cooling of the laser aperture 37.

[0038] Example 3

[0039] Because the laser hole opener 37 generates harmful fumes when opening holes in metal components, therefore, based on Embodiment 2, as... Figures 1-5 As shown, the device is also equipped with a purification component 310. The purification component 310 includes a partition plate 3101 installed inside the liquid storage box 391, which divides the interior into two chambers. A suction machine 3102 is installed at the bottom right side of the liquid storage box 391. The air inlet of the suction machine 3102 is equipped with a smoke extraction pipe 3103, and a smoke collection hood 3104 is installed at the bottom of the smoke extraction pipe 3103. The air outlet of the suction machine 3102 is equipped with a delivery pipe 3105 whose end extends into the bottom of the right water storage chamber of the liquid storage box 391. An exhaust pipe 3106 is installed at the top of the right water storage chamber of the liquid storage box 391. When the suction machine 3102 is started, the harmful gases generated during the opening process are sucked into the delivery pipe 3105 through the cooperation of the smoke extraction pipe 3103 and the smoke collection hood 3104, and injected into the water body of the right water storage chamber of the liquid storage box 391, thereby purifying the harmful gases with water and preventing the harmful gases from spreading and affecting the health of the operators.
