[0002] The CNC polishing machine features servo constant pressure polishing, with real-time compensation for consumable wear; the polishing disc is driven by an independent motor to rotate, automatically switching between forward and reverse rotation to meet different process requirements; the CNC polishing machine is mainly used for polishing 2.5D and 3D cover plates of mobile phones made of non-metallic materials such as glass and ceramics, as well as back covers of metal materials such as aluminum alloys.
[0003] Currently, existing technology CN217513609U discloses an intelligent precision fully automatic CNC polishing machine, including a worktable. An L-shaped support plate is fixedly connected to the rear side of the top surface of the worktable. A rotating motor is bolted to the center of the top surface of the L-shaped support plate. The bottom of the output end of the rotating motor passes through the L-shaped support plate and is fixedly connected to a polishing device. A placement plate is welded to the front side of the center of the top surface of the worktable. A dust collection port is opened on the surface of the top of the worktable, located on the outer ring of the placement plate. This invention solves the problems of existing CNC polishing machines, which cannot complete the rough polishing to fine polishing operation, requiring the polishing machine to be replaced after polishing the object; cannot absorb the dust generated during the polishing process, resulting in a large amount of dust overflowing and polluting the environment; and cannot clamp the polished object, making the object easy to move during the polishing process. These problems lead to low polishing efficiency, low quality, and environmental pollution in CNC polishing machines.
[0004] When the CNC polishing machine polishes the workpiece, the pressure of the polishing wheel on the plate is converted into stress. However, excessive stress will affect the surface quality of the plate or damage the internal structure, thus affecting the polishing efficiency of the polishing machine. Utility Model Content
[0005] The purpose of this utility model is to provide a CNC automatic polishing machine, which aims to solve the problem that stress affects the surface quality of the plate or damages the internal structure during polishing by existing CNC polishing machines.
[0006] To achieve the above objectives, this utility model provides a CNC automatic polishing machine, including a polishing machine body and a buffer assembly, wherein the buffer assembly includes a buffer rod, a mounting block, a vacuum suction cup, a suction pipe and a suction pump;
[0007] The buffer rod is fixedly connected to the polishing machine body and is located on one side of the polishing machine body. The mounting block is fixedly connected to the buffer rod and is located at the top of the buffer rod. The vacuum suction cup is fixedly connected to the mounting block and is located on the side of the mounting block away from the buffer rod. The suction pipe is connected to the vacuum suction cup and is located on one side of the vacuum suction cup. The suction pump is connected to the suction pipe and is located on the side of the suction pipe away from the vacuum suction cup.
[0008] The buffer rod includes a damping rod and a spring. The damping rod is fixedly connected to the polishing machine body and is located on one side of the polishing machine body. The spring is sleeved on the outside of the damping rod.
[0009] The suction pipe includes a main suction pipe and a branch suction pipe. The main suction pipe is connected to the suction pump and is located on one side of the suction pump. The branch suction pipe is connected to the vacuum suction cup and is connected to the main suction pipe, and is located between the vacuum suction cup and the main suction pipe.
[0010] The CNC automatic polishing machine further includes an air suction hood, a dust suction pipe, a dust collection box, and an exhaust fan. The air suction hood is fixedly connected to the polishing machine body and is located on both sides of the vacuum suction cup. The dust collection box is fixedly connected to the polishing machine body and is located on one side of the polishing machine body. The dust suction pipe is connected to the air suction hood and the dust collection box and is located between the dust collection box and the air suction hood. The exhaust fan is connected to the dust collection box and is located outside the dust collection box.
[0011] The dust collection box includes a box body, a filter screen, and a magnetic block.

[0012] This utility model discloses a CNC automatic polishing machine. The polishing machine body is used to polish the sheet metal. The buffer assembly is used to fix the sheet metal and buffer the polishing stress during the polishing process, preventing stress from affecting the surface quality or damaging the internal structure of the sheet metal. The mounting block is used to fix the vacuum suction cup to the buffer rod. Specifically, the worker uses their hand to place the sheet metal to be processed on the vacuum suction cup and starts the suction pump through the controller. The operation of the suction pump causes the suction pipe to generate suction force, thereby sucking out the air in the vacuum suction cup, forming a vacuum, and thus adsorbing and fixing the sheet metal. At this time, the polishing machine body, based on CNC program control, automatically polishes the fixed sheet metal to complete the processing of the sheet metal. During the polishing process of the polishing machine body, the sheet metal is subjected to stress that presses down on the vacuum suction cup and compresses the buffer rod. The buffer rod buffers the stress, effectively preventing the stress from being unable to dissipate and causing damage to the surface quality or internal structure of the sheet metal. This greatly improves the polishing efficiency of the sheet metal and solves the problem that stress affects the surface quality or damages the internal structure of the sheet metal during polishing in existing CNC polishing machines.

Detailed Implementation
[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0020] Please see Figures 1 to 4 This utility model provides a CNC automatic polishing machine, including a polishing machine body 1 and a buffer assembly 2. The buffer assembly 2 includes a buffer rod 3, a mounting block 4, a vacuum suction cup 5, a suction pipe 6, and a suction pump 7. The buffer rod 3 is fixedly connected to the polishing machine body 1 and is located on one side of the polishing machine body 1. The mounting block 4 is fixedly connected to the buffer rod 3 and is located at the top of the buffer rod 3. The vacuum suction cup 5 is fixedly connected to the mounting block 4 and is located on the side of the mounting block 4 away from the buffer rod 3. The suction pipe 6 is connected to the vacuum suction cup 5 and is located on one side of the vacuum suction cup 5. The suction pump 7 is connected to the suction pipe 6 and is located on the side of the suction pipe 6 away from the vacuum suction cup 5.
[0021] In this embodiment, the polishing machine body 1 is used to polish the board, the buffer assembly 2 is used to fix the board and buffer the polishing stress when the polishing machine body 1 polishes the board, so as to avoid the stress affecting the surface quality or internal structure damage of the board. The mounting block 4 is used to fix the vacuum suction cup 5 on the buffer rod 3. Specifically, the worker uses his hand to place the board to be processed on the vacuum suction cup 5 and starts the suction pump 7 through the controller. The operation of the suction pump 7 causes the suction pipe 6 to generate suction force, thereby sucking out the air in the vacuum suction cup 5 and forming a vacuum, thereby adsorbing and fixing the board. At this time, the polishing machine body 1 automatically polishes the fixed board based on CNC program control, completing the processing of the board. During the polishing process of the polishing machine body 1, the board is subjected to stress that presses down on the vacuum suction cup 5 and compresses the buffer rod 3, thereby buffering the stress through the buffer rod 3, effectively avoiding the phenomenon that the stress cannot be dissipated and causes damage to the surface quality or internal structure of the board, greatly improving the polishing efficiency of the board and solving the problem that stress affects the surface quality or internal structure of the board during polishing of existing CNC polishing machines.
[0022] Furthermore, the buffer rod 3 includes a damping rod 8 and a spring 9. The damping rod 8 is fixedly connected to the polishing machine body 1 and is located on one side of the polishing machine body 1. The spring 9 is sleeved on the outside of the damping rod 8.
[0023] In this embodiment, when the plate is under stress, the vacuum suction cup 5 is pressed down, and the vacuum suction cup 5 then presses down the damping rod 8. The damping rod 8 dissipates the corresponding force by squeezing the buffer medium inside. The spring 9 is used in conjunction with the damping rod 8 to improve the purpose of stress buffering.
[0024] Furthermore, the suction pipe 6 includes a main suction pipe 10 and a side suction pipe 11. The main suction pipe 10 is connected to the suction pump 7 and is located on one side of the suction pump 7. The side suction pipe 11 is connected to the vacuum suction cup 5 and is connected to the main suction pipe 10, and is located between the vacuum suction cup 5 and the main suction pipe 10.
[0025] In this embodiment, the number of suction branch pipes 11 corresponds to the number of vacuum suction cups 5, and they are connected to the main suction pipe 10 to form a passage. When the suction pump 7 is operating, the main suction pipe 10 draws in air, and at the same time, the air in the vacuum suction cup 5 is absorbed through the main suction pipe 10 to ensure the stability of the plate fixing.
[0026] Furthermore, the CNC automatic polishing machine also includes an air suction hood 12, a dust suction pipe 13, a dust collection box 14, and an exhaust fan 15. The air suction hood 12 is fixedly connected to the polishing machine body 1 and is located on both sides of the vacuum suction cup 5. The dust collection box 14 is fixedly connected to the polishing machine body 1 and is located on one side of the polishing machine body 1. The dust suction pipe 13 is connected to the air suction hood 12 and the dust collection box 14, and is located between the dust collection box 14 and the air suction hood 12. The exhaust fan 15 is connected to the dust collection box 14 and is located outside the dust collection box 14.
[0027] In this embodiment, the exhaust fan 15 operates to draw in air, which causes the dust suction pipe 13 to draw in air, thereby causing the suction hood 12 to absorb the dust scattered during polishing, thus preventing dust from scattering and polluting the working environment. The dust suction pipe 13 guides the dust into the dust collection box 14, where it is removed by the dust collection box 14.
[0028] Furthermore, the dust collection box 14 includes a box body 16, a filter screen 17, and a magnetic block 18. The box body 16 is fixedly connected to the polishing machine body 1 and is located on one side of the polishing machine body 1. The filter screen 17 is detachably connected to the box body 16 and passes through the box body 16. The magnetic block 18 is fixedly connected to the filter screen 17 and is located on one side of the filter screen 17.
[0029] In this embodiment, the housing 16 provides installation conditions for the exhaust fan 15 and the filter plate 17. The filter plate 17 is used to filter dust in the air introduced by the suction pipe 13. The magnetic block 18 is provided to fix the filter plate 17 on the housing 16.
