s3, longitudinally cutting a display plate: the cutting knife (282) is pushed downwards by the first electric push rod (283), the cutting knife (282) moves downwards along the circular plate (281) until the display panel is cut through, then the first rod frame (284) is driven to move along the connecting piece (280) by the second electric slide block (285), the first rod frame (284) drives the first electric push rod (283) to move synchronously, and the first electric push rod (283) drives the cutting knife (282) to move synchronously along with the first electric push rod to longitudinally cut the display panel;
s4, transversely cutting a display plate: after the longitudinal cutting is finished, the cutter (282) resets, then the circular ring (27) is driven by the circular arc electric slide block (26) to rotate 90 degrees clockwise, the circular ring (27) drives the slitting set (28) to move synchronously, and then the S3 operation is repeated to transversely cut the display panel;
s5, display panel dicing and picking: after the display panel is integrally cut, the cutting group (28) is restored to the original state, the limiting rod (22) is dismounted manually, the top plate (20) is rotated to the original position, then the movable plate (24) is driven to reset through the first electric sliding block (25), and then the display panel cut blocks are picked up manually;
s6, clamping the display panel at intervals: the display panel cut block picked up in a manual mode is placed on the upper end face of the bottom plate (30), the cutting face of the display panel faces the outer side of the bottom plate (30), one corner of the display panel is tightly attached to the angle plate (32), and then the pressing plate (36) is pushed downwards through the second electric push rod (35) until the pressing plate (36) presses the display panel cut block;
s7, grinding preparation: the third electric sliding block (370) drives the motor (371) to move towards the display panel cutting direction along the first groove, the middle shaft (372) drives the disc (373) to move synchronously along with the motor (371), and the disc (373) drives the first connecting plate (374) and the second connecting plate (375) to move synchronously until the grinding block (378) is tightly attached to the cutting surface of the display panel cutting;
s8, cutting surface polishing: drive jackshaft (372) through motor (371) and do reciprocal positive and negative rotary motion, jackshaft (372) drive disc (373) simultaneous movement, link board (374) and No. two link board (375) along with disc (373) simultaneous movement, riser (377) drive sanding block (378) along with polishing along the cutting plane reciprocating motion of display panel stripping and slicing.
