The protective sleeve 280 is fixedly connected to the shell of the machine body 100 through a positioning connector 283. A lead groove 281 is provided on the top of the protective sleeve 280 close to the side of the machine body 100. A top cover 282 is installed on the top of the protective sleeve 280 through bolts. A first limiting rod 2821 and a second limiting rod 2822 are respectively screwed on the top cover 282. At least two of the first limiting rod 2821 and the second limiting rod 2822 are equidistantly provided. A trapezoidal hand-tightening block 2823 is integrally formed on the top of the first limiting rod 2821 and the second limiting rod 2822. The bottom of the first limiting rod 2821 is inserted into the interior of the connecting column 260, and the bottom of the second limiting rod 2822 is inserted into the interior of the connecting ring 270.

When in use, the cylinder 240 and the fixing ring 250 rotate with the round shell 200, and the protective sleeve 280 cannot rotate under the action of the positioning connector 283. The connecting column 260 cannot rotate under the action of the first limiting rod 2821, and the connecting ring 270 cannot rotate under the action of the second limiting rod 2822. This prevents the first wiring clip 262 and the second wiring clip 272 from moving, and the leads connected to the first wiring clip 262 and the second wiring clip 272 will not be tangled. The first limiting rod 2821 not only prevents the connection column 260 from rotating, but also adjusts the tightness of the connection column 260 and the cylinder 240 by twisting the first limiting rod 2821, which is conducive to stable power transmission between the connection column 260 and the cylinder 240. Similarly, the second limiting rod 2822 not only prevents the connection ring 270 from rotating, but also facilitates stable power transmission between the connection ring 270 and the rotating ring 252.

The heat dissipation holes 202 facilitate heat dissipation of the electrical appliances inside the circular shell 200. The protective sleeve 280 not only provides a carrier to prevent the connecting column 260 and the connecting ring 270 from rotating and prevents the lead wires from being exposed, but also effectively prevents dust from entering the interior of the heat dissipation holes 202, playing multiple roles.

[0063] See also Figure 2 , further comprising a motor 300 for driving the circular shell 200 to rotate, the motor 300 being mounted on the middle of the top of the disc 310 by bolts, at least two legs 320 being mounted at equal angles on the bottom of the circular shell 200, the bottoms of the legs 320 being mounted with a mounting frame rotatably mounted with rollers 321, and a roller groove 322 for the rollers 321 to roll is provided on the top of the disc 310;

[0065] An object sensor is installed on the top inner wall of the working tank 110, and the object sensor is electrically connected to the intelligent manipulator. The intelligent manipulator controls the first electric cylinder 152, the second electric cylinder 154, the third electric cylinder 156, the motor 300 and the oil cylinder 400. The intelligent manipulator is signal-connected to the intelligent controller 201. A gravity sensor is installed on the positioning plate 231, and the gravity sensor is electrically connected to the intelligent controller 201.

[0066] How to use this three-dimensional etching device for the metal support of the mobile phone motherboard:

[0067] Put the mobile phone motherboard metal support, hereinafter referred to as the support, into the card slot 230, and place the support on the positioning plate 231 and the rectangular cutout 2321. The positioning plate 231 is equipped with a gravity sensor. After the gravity sensor detects the metal support, the intelligent controller 201 controls the electric push rod 2322 to start, and extends the two movable clamping plates 232, and the two movable clamping plates 232 are extended to clamp the support;

[0068] The intelligent controller 201 sends a signal to the intelligent manipulator through the wireless transceiver module, and the intelligent manipulator controls the motor 300 to start and drive the round shell 200 to rotate. When the intelligent manipulator detects that the support member enters the interior of the working groove 110 through the object sensor, the motor 300 is controlled to stop rotating;

[0069] The intelligent controller controls two sets of driving mechanisms, so that the upper and lower laser etching heads 141 move three-dimensionally to perform laser etching on the upper and lower sides of the metal part, and can also perform separate etching on the top or bottom of the metal part;

[0070] After etching is completed, the intelligent manipulator controls the motor 300 to rotate. When the intelligent manipulator detects that the support member is separated from the working slot 110 through the object sensor, the intelligent manipulator sends a signal to the intelligent controller 201. The intelligent controller 201 controls the electric push rod 2322 to drive the mobile clamping plate 232 to retract into the inside of the round shell 200. At this time, the etched metal part automatically falls off from the inside of the slot 230, and then the mobile clamping plate 232 returns to its original position.

[0071] Repeat the above steps to continuously perform three-dimensional etching on the top and bottom of the metal part.

[0072] In summary:

[0073] The device for three-dimensionally etching the metal support of the mobile phone mainboard can simultaneously perform three-dimensional laser etching on the upper and lower sides of the support, and can also perform separate etching on the top or bottom of the metal part. It has multiple functions and can continuously rotate and feed.

[0074] The clamping mechanism is composed of two positioning plates 231 and two movable clamping plates 232. The metal support is placed on the positioning plates 231 and the rectangular cutout 2321. The two movable clamping plates 232 are extended to clamp the metal support. When the movable clamping plates 232 are retracted, the metal support automatically falls off from the slot 230, which facilitates the clamping and unloading of the metal support.

[0075] The upper circular shell 210 and the lower circular shell 220 can be assembled and disassembled by disassembling the screws, and the installation of the internal components of the circular shell 200 can be facilitated;

[0076] The heat dissipation holes 202 facilitate heat dissipation of the electrical appliances inside the round shell 200. The protective sleeve 280 not only provides a carrier to prevent the connection column 260 and the connection ring 270 from rotating and prevents the lead wires from being exposed, but also effectively prevents dust from entering the heat dissipation holes 202, thus playing multiple roles.

[0077] The neutral wire and the live wire pass through the inside of the lead groove 281, the first wiring clamp 262 and the second wiring clamp 272 are connected to the live wire and the neutral wire respectively, and the power connector of each electrical appliance is connected to the first wiring ring 241 and the second wiring ring 251, so as to facilitate power supply to each electrical appliance. When in use, the cylinder 240 and the fixing ring 250 rotate with the round shell 200, and the protective sleeve 280 cannot rotate under the action of the positioning connector 283. The connecting column 260 cannot rotate under the action of the first limiting rod 2821, and the connecting ring 270 cannot rotate under the action of the second limiting rod 2822, which makes the first wiring clamp 262 and the second wiring clamp 272 not move, and the leads connected to the first wiring clamp 262 and the second wiring clamp 272 will not be entangled;

[0078] The first limiting rod 2821 not only prevents the connecting column 260 from rotating, but also can adjust the tightness of the fit between the connecting column 260 and the cylinder 240 by twisting the first limiting rod 2821, which is beneficial to the stable power transmission between the connecting column 260 and the cylinder 240. Similarly, the second limiting rod 2822 not only prevents the connecting ring 270 from rotating, but also is beneficial to the stable power transmission between the connecting ring 270 and the rotating ring 252.
