[0045] The rotating shaft of the polishing wheel 33 is rotatably connected to the lifting plate 32 via the connecting frame 34. The top of the connecting frame 34 is fixedly connected to the lifting plate 32, and the bottom of the connecting frame 34 is annular and rotatably connected to the rotating shaft.

[0046] The synchronization assembly includes a first synchronization pulley, a second synchronization pulley 35, and a synchronization belt. The polishing wheel 33 is coaxially connected to a rotating shaft. The first synchronization pulley is coaxially connected to the output shaft of the drive motor 331. The second synchronization pulley 35 is coaxially connected to the rotating shaft of the polishing wheel 33. The first synchronization pulley and the second synchronization pulley 35 are connected by a synchronization belt, which is simultaneously fitted onto the first synchronization pulley and the second synchronization pulley 35 and kept taut.

[0047] Each grinding mechanism has a positioning component 4 at three locations for positioning the workpiece 9. The positioning component 4 includes a first ejector pin 41 and a second ejector pin 42. The first ejector pin 41 and the second ejector pin 42 are located at opposite ends of the workpiece 9 along its axis. The height of the first ejector pin 41 and the second ejector pin 42 is the same as the height of the workpiece 9 after it has been raised. The first ejector pin 41 moves toward or away from the workpiece 9 via a sliding cylinder 411, and the second ejector pin 42 moves toward or away from the workpiece 9 via a sliding cylinder 421.

[0050] A cover 11 is installed on the frame 1. The carrier 21 at the far left end is located outside the left side of the cover 11. The cover 11 has a loading port 111 for the leftmost end of the carrier 2 to pass through. When loading, the operator places the workpiece 9 inside the carrier 21 outside the cover 11.

[0052] An infrared sensor 221 is installed on the top surface of the protective frame 22. The height of the infrared sensor 221 is the same as the height of the workpiece 9 after it is raised. The infrared sensor 221 is used to detect whether there is a workpiece 9 in the corresponding carrier 21. When the infrared sensor 221 detects that there is no workpiece 9, the infrared sensor 221 works with the control system and emits a prompt sound through the alarm module in the control system to remind the staff to place the workpiece 9.

[0053] The distance between two adjacent carriers 21 is half the distance between two adjacent grinding mechanisms 3. The infrared sensor 221 and the positioning component 4 are alternately set, and the leftmost infrared sensor 221 is located to the left of the leftmost positioning component 4.

[0054] Below the shelf 2, there is a lifting cylinder 5 and a translation component 6. After the lifting cylinder 5 drives the shelf 2 to rise, the translation component 6 drives the shelf 2 to move to the right, so that the leftmost carrier 21 moves to below the leftmost polishing wheel 33. After polishing is completed, the shelf 2 descends and then moves to the left to its original position.

[0055] The lifting cylinder 5 is located below the shelf 2, and the piston rod of the lifting cylinder 5 is fixedly connected to the bottom surface of the shelf 2.

[0057] The right side of the grinding mechanism 3 at the far right end is provided with a cleaning component 7. The cleaning component 7 includes a fixed plate 71, a lifting block 72, and a cleaning roller 73. The fixed plate 71 is fixedly installed on the frame 1. The lifting block 72 is lifted and lowered on the fixed plate 71 by a second lifting cylinder 721. The second lifting cylinder 721 is fixed on the fixed plate 71, and the piston rod of the second lifting cylinder 721 is fixedly connected to the top surface of the second lifting block 72. An L-shaped mounting plate 74 is provided on the lifting block 72. The cleaning roller 73 is rotatably mounted on the vertical part of the mounting plate 74. A reduction motor 75 is provided on the horizontal part of the mounting plate 74. The output shaft of the reduction motor 75 passes through the vertical part of the mounting plate 74 and is coaxially connected to the cleaning roller 73. The outer peripheral wall of the cleaning roller 73 is provided with bristles. The cleaning roller 73 descends until the bristles of the cleaning roller 73 abut against the outer peripheral wall of the workpiece 9.

[0058] A set of positioning components 4 is also provided at the cleaning component 7. The cleaning roller 73 rotates to make the bristles contact the outer peripheral wall of the workpiece 9 and remove the waste generated during polishing.

[0059] The shelf 2 is equipped with a rust prevention component 8, which includes a housing 81, a first nozzle 82, and a second nozzle 83. The housing 81 has an installation chamber and is open at both ends along the length of the shelf 2. The housing 81 is fixedly installed on the shelf 2.

The first nozzle 82 is located to the left of the second nozzle 83.

[0060] By using air cutting and rust prevention treatment, the cleanliness of the surface of workpiece 9 and the quality of workpiece 9 after polishing are improved.

[0061] The grinding mechanism 3, cleaning component 7, and rust prevention component 8 are all housed inside the machine cover 11, reducing the risk to the health of operators.

[0062] The automated polishing process reduces the labor intensity of operators, saves management costs, improves the consistency and efficiency of workpiece polishing, reduces the possibility of human error, and improves product quality and polishing efficiency.

[0063] The implementation principle of an automated polishing machine according to an embodiment of this application is as follows:

[0064] The operator places the workpiece 9 inside the carrier 21 outside the machine cover 11. Then, the lifting cylinder 5 raises the carrier 2 and the translation component 6 moves the carrier 2 to the right, so that all the workpieces 9 move to the right. At this time, the workpiece 9 that was just placed first moves to the infrared sensor 221. Then, the translation component 6 moves the carrier 2 to the right again, so that all the workpieces 9 move to the right again. At this time, the workpiece 9 that was just placed moves from the infrared sensor 221 to the positioning component 4 corresponding to the leftmost grinding mechanism 3. After the workpiece 9 is pressed and positioned by the ejector pin 41 and ejector pin 42, the carrier 2 is driven to descend. The translation component 6 then moves the carrier 2 to the left twice to reset. Then, the operator places the next workpiece 9 inside the carrier 21 outside the machine cover 11.

[0065] Then, the lifting cylinder 5 raises the carrier 2, and the translation component 6 moves the carrier 2 to the right. The leftmost infrared sensor 221 detects the workpiece 9 that was just placed, and the second infrared sensor 221 detects the previous workpiece 9. The translation component 6 then moves the carrier 2 to the right again, so that all the workpieces 9 move to the right. At this time, the previous workpiece 9 moves from the second infrared sensor 221 to the second grinding mechanism 3, and the workpiece 9 that was just placed moves from the leftmost infrared sensor 221 to the positioning component 4 corresponding to the leftmost grinding mechanism 3. This cycle continues.

[0066] When the workpiece 9 moves to the cleaning component 7, the lifting cylinder 721 drives the cleaning roller 73 to descend until the bristles of the cleaning roller 73 abut against the outer peripheral wall of the workpiece 9, and rotates the cleaning roller 73 and the workpiece 9 to remove the debris on the workpiece 9.

[0067] When the workpiece 9 moves to the anti-rust component 8, nozzle one sprays air towards the workpiece 9 through an air pump, and nozzle two sprays anti-rust liquid towards the workpiece 9 through a liquid pump, further cleaning the debris on the surface of the workpiece 9 and performing anti-rust treatment.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
