[0042] The effect achieved by the entire mechanism is: when it is necessary to perform polishing and grinding operations on the cover of the mobile communication device, the box cover 203 is directly removed at this time, and at the same time, a proper amount of dichloromethane solution is injected into the liquid storage tank 201 until the solution height inside the liquid storage tank 201 submerges the output ends of the two discharge pipes 208, and then the box cover 203 is installed back to the original position, and a sealing plug 219 is installed inside each cylindrical hole 205, and then the transparent baffle 302 is moved out from between the insides of the two L-shaped blocks 301 by using the rectangular groove 305. At this time, the moved transparent baffle 302 will cause the two limit grooves 303 to be separated from the two limit blocks 304 respectively. When the transparent baffle 302 is removed from between the insides of the two L-shaped blocks 301, the required The polished cover plate for mobile communication equipment is placed on the placement table 403 and lightly pressed by hand. At the same time, the micro vacuum pump 407 is directly started through the cooperation of the control switch 409 and the battery 406. At this time, the input end of the started micro vacuum pump 407 will generate a strong suction force. At this time, with the cooperation of the suction cup 410, the cover plate can be directly fixed on the placement table 403, and then the transparent baffle 302 is installed between the inside of the two L-shaped blocks 301 by using the rectangular groove 305 until the two limit grooves 303 are respectively connected with the two limit blocks 304. Then, the use procedures of the motor controller 411 and the control box 6 are set at the same time, and the motor controller 411 is started. At this time, the started motor controller 411 will be in the configuration of the driver 412 When the cover plate is closed, the stepper motor 401 is directly controlled to drive the connecting rod 402 to rotate at an accurate angle. At this time, the rotating connecting rod 402 will electrically rotate the cover plate fixed on the placement table 403. When the cover plate rotates to the first surface, the control box 6 is directly used to control the polishing and grinding machine 5 to polish the first surface of the cover plate. When the first surface of the cover plate is polished, the stepper motor 401 will drive the placement table 403 to rotate 90 degrees through the connecting rod 402, and stop after the rotation. At the same time, the grinding part of the polishing and grinding machine 5 will move backward. When the cover plate rotates to the second surface, the polishing and grinding machine 5 will move over again to grind the second surface of the cover plate. This reciprocating process can polish and grind each edge surface of the cover plate. When When the cover plate is polished, the fan controller 217 is directly used to start the two fan bodies 207 at the same time with the cooperation of the synchronous controller 218. At this time, the input ends of the two started fan bodies 207 will generate a large suction force. At this time, with the cooperation of the three-way pipe 211, the round pipe 212 and the T-slot 214, the input ends of all the air inlet holes 215 can obtain a strong suction force. At this time, each air inlet hole 215 that obtains the suction force will absorb almost all the plastic powder generated when the cover plate is polished. At this time, the sucked plastic powder will directly gather together in the inside of the T-slot 214, and then enter the inside of the round pipe 212. After that, the plastic powder is directly diverted through the cooperation of the three-way pipe 211 and the two fan bodies 207.The plastic powder is directed to the inside of the two discharge pipes 208 respectively, and then the plastic powder entering the two discharge pipes 208 will be directly guided to the dichloromethane liquid under the cooperation of the corresponding discharge hole 210 and the cylindrical block 209. When the plastic powder is discharged into the liquid, the plastic powder will be directly dissolved in the liquid under the action of the dichloromethane liquid. When the gas discharged from the discharge hole 210 of the plastic powder enters the liquid, it will generate a driving force on the liquid around it. At this time, the moving liquid will directly drive the corresponding stirring blade 206 to rotate under the cooperation of the bearing and the rotating rod 216. At this time, each rotating stirring blade 206 will also drive the liquid at other positions inside the liquid storage tank 201 to move, so that the plastic powder entering the dichloromethane liquid can be fully dissolved. When it is necessary to release some pressure inside the liquid storage tank 201, part of the sealing plug 219 can be directly removed to allow the pressure inside the liquid storage tank 201 to dissipate from the vent 204.

[0043] Among them, the polishing and grinding machine 5 is mainly composed of a control system, a polishing disc, a motor and a base. Its simple working principle is that the motor drives the polishing and grinding disc to rotate, and then the control system drives the rotating polishing disc to move forward, backward, left and rear through the cooperation of the base to polish and grind the object.

[0044] Among them, the fan body 207, the fan controller 217, the synchronous controller 218, the stepper motor 401, the battery 406, the micro vacuum pump 407, the control switch 409, the motor controller 411 and the driver 412 are all existing technologies and will not be explained in detail here.
