[0046] Working principle: The workpieces 101 to be processed are stacked and placed in the storage frame 7. The push drive device 11 drives the push plate to move to the left along the bottom end of the storage frame 7, and a row of several workpieces 101 to be processed in the bottom layer of the storage frame 7 are pushed out of the discharge port 8 and pushed into the clamping groove 24, completing the loading step of the workpieces 101 to be processed.

[0047] During the loading process, the anti-drop limit plate 25 provided at the output end of the clamping groove 24 is driven by the lifting drive device 26 to move upward and pass through the limit perforation to block the workpiece 101 to be processed, thereby preventing the workpiece 101 to be processed from sliding out of the clamping groove 24 due to inertia when the pushing plate pushes the workpiece 101 to be processed.

[0048] After completing the loading of the workpiece 101 to be processed, the limit drive device 23 drives the drive plate 21 to move forward, and the drive plate 21 drives the push piece 19 to slide in the guide plate 20, so that the push piece 19 and the guide limit plate 18 finally cooperate to push against a row of several workpieces 101 to be processed in the clamping groove 24, completing the clamping step of the workpiece 101 to be processed.

[0049] After completing the clamping of the workpiece 101 to be processed, the second servo motor 17 drives the screw to rotate, and then drives the sliding placement seat 15 to move left to the lower side of the grinding mechanism. At this time, the fourth servo motor 31 controls the third servo motor 29 to move downward, and the third servo motor 29 controls the grinding wheel 30 to rotate, thereby grinding the upper surface of the workpiece. During the processing, the first servo motor 5 controls the workbench 2 to slide back and forth, so that the grinding is more uniform.

[0050] After grinding is completed, the fourth servo motor 31 controls the third servo motor 29 to move upward, the third servo motor 29 controls the grinding wheel 30 to stop rotating, and the limit drive device 23 drives the drive plate 21 to move backward, so that the support member 19 no longer clamps the workpiece that has completed the grinding process, and the lifting drive device 26 drives the anti-drop limit plate 25 to move downward and no longer blocks the workpiece. At this time, the sliding drive device 34 drives the sliding plate 33 to slide backward along the fifth slide rail 37, and then the unloading drive device 36 drives the unloading plate 35 to slide to the left. The unloading plate 35 is "L"-shaped, and its lower side can push the workpiece that has completed the grinding process in the clamping groove 24 out of the clamping groove 24 into the unloading plate 35 when the unloading plate 35 moves to the left, and the workpiece then slides along the unloading plate 35 to complete the unloading step of the workpiece.

Any modification or change made by a person familiar with the present technology using the present invention shall fall within the patent scope claimed by the present invention and shall not be limited to those disclosed in the embodiments.
