The application method of the automatic blanking equipment after sintering of the DBC ceramic substrate comprises the following steps:
step (1), placing the substrate after the superposition sintering on a bearing table 37 on a second base 31; then the third electric push rod 33 in the limiting pipe 32 in the turnover structure 3 is driven to extend, and the rack 34 and the turnover arm 36 are moved out of the limiting pipe 32; namely, the electric turning arm 36 is driven by controlling the second motor 35 to rotate 180 degrees to be opposite to the bearing table 37, so that the limiting structure 4 is positioned above the bearing table 37; step (2), the third electric push rod 33 is driven to shrink, the turning arm 36 is driven to descend, the first stop lever (416) and the second stop lever 426 in the clamping unit 41 and the shielding unit 42 are respectively positioned at the front side, the rear side, the left side and the right side of the substrate, the third motor 412 on the first clamping frame 411 and the fourth motor 422 on the second clamping frame 421 are further controlled to drive the second screw rod 413 and the third screw rod 423 to rotate respectively, the corresponding first sliding seat 414 and the second sliding seat 424 are driven to move relatively under force, and the first stop lever (416) and the second stop lever 426 which are respectively fixed on the first clamping frame 415 and the second clamping frame 425 through the first fastening bolt 417 and the second fastening bolt 427 are driven to move relatively so as to clamp the sintered substrate; step (3), the third electric push rod 33 is controlled to extend again, the turning arm 36 is reset and turned for 180 degrees, and then the third electric push rod 33 is driven to shrink and reset, so that the bottommost part of the clamped substrate can be put between two expanding arms 265 in the pushing unit 26; step (4), the first electric push rod 25 in the pushing structure 2 is driven to extend, the pushing frame 261 is driven to move rightwards on the slideway 24, the bottommost substrate is forced to push rightwards by the shielding of the expanding arm 265 (note that the thickness of the pushing frame 261 is smaller than that of the substrate), and then the pushing frame 261 is slid out of the blanking through the conveying plate ladder 22; in addition, the fan 23 can be driven to cool to a certain degree in the pushing process, and the substrate positioned at the bottommost part can fall above the left end of the pushing frame 261 in the pushing process; step (5), after pushing out and blanking, the first electric push rod 25 contracts and resets and drives the pushing frame 261 to move leftwards and reset, at the moment, the substrate at the bottommost part again falls between the two expanding arms 265 again along with the movement of the pushing frame 261 to carry out reciprocating blanking; step (6), according to the difference of the width and the length of the substrate, the first motor 262 on the pushing frame 261 can be controlled to drive the first screw 263 to rotate, so that the two first moving blocks 264 are forced to drive the expanding arms 265 to move relatively or oppositely to adjust the distance, and the second electric push rod 266 can be driven to adjust the distance between the blocking claw 267 and the expanding arms 265 for length adjustment; step seven, according to the thickness of the substrates with different sizes and the difference of the heights of the substrates stacked together, the first fastening bolt 417 or the second fastening bolt 427 can be rotated to adjust the first stop lever (416) and the second stop lever 426 to slide and adjust on the first clamping frame 415 and the second clamping frame 425; when the pushing and blanking process is performed, the heights of the second stop bars 426 positioned on the right side of the second clamping frame 421 in the shielding unit 42, namely opposite to the bearing table 37, need to be adjusted so that the lower walls of the two second stop bars 426 in the direction are positioned above the upper wall of the bottommost substrate and cannot exceed the second substrate, and the second stop bars are used for pushing out the bottommost substrate to prevent shielding; the second stop lever 426 at the left end of the second clamping frame 421 needs to be attached to the upper wall surface of the pushing frame 261 or has a smaller gap; the single substrate can be clamped and overlapped in sequence and then used in unified blanking.
