The bottom inner wall of the shell is conical, and the coolant and debris flow to the edge of the bottom inner wall of the shell, thereby cleaning the bottom inner wall of the shell, and cleaning the coolant and debris at the edge into the filter assembly.

[0018] Furthermore, the engaging and disengaging assembly comprises a long rod and a mounting rod, wherein the mounting rod is mounted on the outer wall of the long rod, the mounting rod penetrates the shell and extends to the interior of the shell, one end of the mounting rod is rotatably connected to the outer wall of the rotating shaft, a screw is rotatably connected to the interior of the long rod, a sliding rod is slidably connected to the top of the long rod, the top of the screw is threadedly connected to the sliding rod, one end of the sliding rod is rotatably connected to the upper module, and the sliding rod is slidably connected to the shell;

[0019] A lower module is installed on the top of the rotating shaft, and the middle frame is arranged between the lower module and the upper module;

[0020] The purpose of the above-mentioned setting is that the rotating drive assembly drives the long rod to rotate through the transmission structure, and the rotation of the long rod causes the sliding rod to rise, thereby adjusting the gap between the lower module and the upper module.

[0027] Further, the grinding drive assembly includes a motor, the motor is installed on the top of the bracket, the motor is connected to an output shaft, the output shaft passes through the shell and extends to the inside of the shell, a grinding head is slidably connected to the outer wall of the output shaft, and a second spring is arranged between the output shaft and the grinding head;

[0028] The purpose of the above arrangement is that the motor drives the output shaft to rotate, and the output shaft drives the grinding head to rotate to grind the outer wall of the middle frame. When the middle frame rotates, due to the difference in length and width, the middle frame pushes the grinding head, and the grinding head slides in the water on the output shaft, and at the same time squeezes the second spring to adapt to the length and width of the middle frame.

[0029] Further, the control member includes a mounting ring, the mounting ring is rotatably connected to the outer wall of one end of the grinding head, a connecting rod is connected to the outer wall of the mounting ring, one end of the connecting rod is rotatably connected to a gripper, and a buckle is installed on the outer wall of the motor.

[0030] The purpose of the above setting is to drive the mounting ring to move when the grinding head moves. The gripper and the buckle are set. After the middle frame is processed, the gripper is buckled on the buckle, and the gripper drives the connecting rod and the mounting ring to move, so that the grinding head is away from the middle frame, making it convenient to take out the middle frame.

[0033] The transmission rod passes through the special-shaped rod and is slidably connected, and the special-shaped rod is slidably connected to the top of the bracket;

[0034] The purpose of the above arrangement is that during the rotation of the middle frame, the length and width of the middle frame alternate with each other and approach the grinding head, so that the grinding head can continuously telescope on the output shaft, thereby driving the mounting ring and the connecting rod to move. During the movement of the special-shaped rod, the transmission rod is driven to move, and the transmission rod drives one of the filter screens to deflect. The transmission rod slides on the special-shaped rod to adapt to its deflection. Because the grinding head continuously telescopes on the output shaft, one of the filter screens resets after deflection and collides with the other filter screen, shaking the debris to the junction of the two filter screens.

[0035] When one of the filters is away from the other filter, the debris is discharged through the drainage channel, and during this process, the coolant stops injecting into the interior of the shell. When one of the filters is close to the other filter to intercept the debris, the coolant is injected into the interior of the shell.

[0036] The present invention has the following beneficial effects:

[0037] (1) The present invention arranges the filter assembly so that during the rotation of the middle frame, the length and width of the middle frame alternate with each other and approach the grinding head, so that the grinding head continuously telescopes on the output shaft, thereby driving the mounting ring and the connecting rod to move. During the movement of the special-shaped rod, the transmission rod is driven to move, and the transmission rod drives one of the filter screens to deflect. The transmission rod slides on the special-shaped rod to adapt to its deflection. Because the grinding head continuously telescopes on the output shaft, one of the filter screens resets after deflection and collides with the other filter screen, shaking the debris to the junction of the two filter screens.

[0038] When one of the filters is away from the other, the debris is discharged through the drainage channel. During this process, the coolant stops being injected into the interior of the shell. When one of the filters is close to the other filter and can intercept the debris, the coolant is injected into the interior of the shell to separate the coolant and the debris, thereby solving the problem of burrs on the middle frame of the mobile phone and the inconvenience of collecting burr debris.

[0039] (2) The present invention provides a second spring so that the motor drives the output shaft to rotate, and the output shaft drives the grinding head to rotate to grind the outer wall of the middle frame. When the middle frame rotates, due to the difference in length and width, the middle frame pushes the grinding head, and the grinding head slides on the output shaft and squeezes the second spring at the same time, thereby adapting to the length and width of the middle frame.

[0040] (3) The present invention provides a shell and a cover plate. The port provided on the outer wall of the shell is used to facilitate taking the middle frame out of the shell. The circular plate and the vertical plate seal the two ports of the shell. Thus, during the grinding process of the middle frame, the middle frame is in a closed state, which reduces the dust in the external air and has a certain influence on the grinding process. At the same time, it is prevented that the debris generated during the processing has an adverse effect on the workers.

[0041] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] As an implementation method, Figure 7 As shown, further:

[0087] A special-shaped rod 504 is installed on the lower surface of the connecting rod 503. The filter assembly 7 includes a filter screen 701 and a drainage channel 702.

[0090] In this embodiment, the purpose of the above arrangement is that during the rotation of the middle frame 12, the length and width of the middle frame 12 alternate with each other and approach the grinding head 303, so that the grinding head 303 is continuously telescopically moved on the output shaft 302, thereby driving the mounting ring 501 and the connecting rod 503 to move, and during the movement of the special-shaped rod 504, the transmission rod 703 is driven to move, and the transmission rod 703 drives one of the filter screens 701 to deflect, and the transmission rod 703 slides on the special-shaped rod 504 to adapt to its deflection. Because the grinding head 303 is continuously telescopically moved on the output shaft 302, one of the filter screens 701 is reset after deflection, collides with the other filter screen 701, and shakes the debris to the junction of the two filter screens 701;

[0091] When one of the filters 701 is away from the other filter 701, the debris is discharged through the drainage channel 702. During this process, the coolant stops injecting into the interior of the shell 4. When one of the filters 701 is close to the other filter 701 and can intercept the debris, the coolant is injected into the interior of the shell 4.

[0092] Working principle: The port provided on the outer wall of the shell 4 is convenient for taking the middle frame 12 out of the inside of the shell 4. The circular plate 601 and the vertical plate 602 seal the two ports of the shell 4, so that during the grinding process of the middle frame 12, it is in a closed state, reducing the dust in the external air, which has a certain influence on the grinding process, and at the same time avoiding the debris generated by the processing from causing adverse effects on the staff;

[0093] The servo motor 201 drives the second pulley 1102 to rotate through the rotating shaft 202, and the second pulley 1102 drives the first pulley 1101 to rotate through the belt 1103, and the first pulley 1101 drives the long rod 901 to rotate, and the long rod 901 rotates to raise the sliding rod 903, so as to adjust the gap between the lower module 205 and the upper module 206. After the adjustment, the middle frame 12 is placed on the lower module 205, and the long rod 901 rotates to lower the sliding rod 903, and the upper module 206 is aligned with the middle frame 12, so that the upper module 206 cooperates with the lower module 205 to clamp the middle frame 12, and the servo motor 201 drives the lower module 205, the upper module 206 and the middle frame 12 to rotate through the rotating shaft 202;

[0094] The motor 301 drives the output shaft 302 to rotate, and the output shaft 302 drives the grinding head 303 to rotate to grind the outer wall of the middle frame 12. When the middle frame 12 rotates, because the length and width are different, the middle frame 12 pushes the grinding head 303, and the grinding head 303 slides on the output shaft 302, and at the same time squeezes the second spring 304, so as to adapt to the length and width of the middle frame 12;

[0095] The servo motor 201 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the brush 10 to make a circular motion on the bottom inner wall of the housing 4. The bottom inner wall of the housing 4 is tapered, and the coolant and debris flow toward the edge of the bottom inner wall of the housing 4, thereby cleaning the bottom inner wall of the housing 4, and cleaning the coolant and debris at the edge into the filter assembly 7;

[0096] When the grinding head 303 moves, the mounting ring 501 is driven to move, and the gripper 502 and the ring buckle 13 are set. After the processing of the middle frame 12 is completed, the gripper 502 is buckled on the ring buckle 13, and the gripper 502 drives the connecting rod 503 and the mounting ring 501 to move, so that the grinding head 303 is away from the middle frame 12, so that the middle frame 12 can be taken out conveniently;

[0097] During the rotation of the middle frame 12, the length and width of the middle frame 12 alternate with each other and approach the grinding head 303, so that the grinding head 303 is continuously telescopically moved on the output shaft 302, thereby driving the mounting ring 501 and the connecting rod 503 to move. During the movement of the special-shaped rod 504, the transmission rod 703 is driven to move, and the transmission rod 703 drives one of the filter screens 701 to deflect, and the transmission rod 703 slides on the special-shaped rod 504 to adapt to its deflection. Because the grinding head 303 is continuously telescopically moved on the output shaft 302, one of the filter screens 701 is reset after deflection, collides with the other filter screen 701, and shakes the debris to the connection between the two filter screens 701;

[0098] When one of the filters 701 is away from the other filter 701, the debris is discharged through the drainage channel 702. During this process, the coolant stops being injected into the interior of the shell 4. When one of the filters 701 is close to the other filter 701 and can intercept the debris, the coolant is injected into the interior of the shell 4, thereby separating the coolant and the debris.

[0102] Step 2: The cover plate is used to seal the shell, and the outer wall of the middle frame is polished by a polishing drive assembly. The polishing end of the polishing drive assembly is a retractable structure, and the length and width of the middle frame are adaptively adjusted;

[0103] Step 3: coolant is introduced into the interior of the housing through the liquid inlet, and the generated coolant and debris are discharged to the filter assembly, and the coolant and debris are filtered by the filter assembly, so that the coolant is discharged first;

[0104] Step 4: The control component is controlled by extending and retracting the grinding end of the grinding drive component, and the control component drives the filter component to operate to discharge the debris on the filter component;

[0105] Step 5: Use the control part to control the grinding end of the grinding drive assembly to move away from the middle frame, the buckle limits the control part, the rotating drive assembly and the clutch assembly release the limit on the middle frame, take out the cover plate, and take out the middle frame.
