(2) Nickel plate hooking: when the cylinder A extends, reaches the high-temperature flow line, the cylinder B extends, the right-angle hook plate reaches the nickel plate position, the cylinder A retracts, the right-angle hook plate pushes the nickel plate to the feeding flow line, the cylinder B retracts, and the nickel plate hooking process is completed; (3) Ceramic product carrying: the ceramic product carrying device is operated, and the ceramic product carrying device is at the ceramic product carrying station; the cylinder M is started, the cylinder M extension rod is extended downward, the cylinder N support is pressed downward, the ceramic product positioning plate is pushed downward to cover the sintered ceramic product, and the ceramic product is positioned; the cylinder N is started, the cylinder N pressing plate is pressed downward, the aluminum plate pressing rod is pressed downward, the aluminum plate is pushed downward, at the same time, the cylinder F extends upward, the sintered ceramic product on the ceramic product positioning block is pushed upward and is attracted by the strong magnet head; the cylinder M retracts, the cylinder N extension rod retracts upward, the aluminum plate pressing rod retracts upward, the aluminum plate drives the sintered ceramic product upward; the servo motor D is started, the ceramic product carrying device and the sintered ceramic product are transferred to the ceramic product carrying station through the transfer screw rod; the cylinder M extends, the sintered ceramic product is inserted into the feeding flow line, the cylinder N retracts, the plate with the strong magnet is retracted, the sintered ceramic product is separated from the magnet, the cylinder M retracts, the upper end of the ceramic product is separated from the positioning hole of the ceramic product positioning block, and the carrying is completed; (4) Cooling the sintered ceramic product: the sintered ceramic product passes through the cooling flow line, the right servo motor A is started, the sintered ceramic product moves rightward on the feeding flow line, the sintered ceramic product passes below the cooling rack, and cooling is performed by the cooling fan on the cooling rack; (5) Sintered ceramic product tray loading: on the feeding flow line, the servo motor C, the cylinder J and the cylinder L operate the variable-distance mechanical arm B to variably distance and clamp the ceramic product in the iron tray on the feeding flow line and then carry the ceramic product to the tray on the sintered ceramic product rack; (6) Sintered ceramic product stacking: after the sintered ceramic product is loaded into the tray, the tray is stacked, the tray is first sent to the left support from the tray transfer station by the servo motor B, and then the sintered ceramic product is automatically sequentially lifted and stacked by the cylinder G, the cylinder H and the cylinder I; (3) and (7) detecting whether the ceramic product is taken out: the ceramic product has no detection station for detecting the nickel plate, detecting whether the ceramic product is taken out, the cylinder C extends downward, if the in-place magnetic switch on the cylinder C is not bright, it indicates that there is residual ceramic product on the product seat, after detection, the cylinder C retracts; if there is a product, the product is manually taken away; (8) detecting whether the product seat is taken out: the product seat has no detection station, the cylinder D extends, because the nickel plate is a metal plate, if the electrical circuit is detected after the cylinder D extends, it indicates that the product seat on the nickel plate is missing, after detection, the cylinder D retracts; if the product seat is missing, the product seat is manually supplemented; (9) Put the sintering ceramic products into the nickel plate: on the feeding production line, operate the up-down variable distance mechanical hand A, first open the clamping jaw through the cylinder L, then extend the cylinder J downward, drive the clamping seat plate to move downward, make the upper end of the ceramic products in the material plate enter each clamping jaw respectively, then clamp the ceramic products through the cylinder L, make the cylinder J retract upward, drive the clamping seat plate to move upward, make the ceramic products separate from the material plate, then move the ceramic products to the empty nickel plate through the servo motor C along the slide rail and drive the clamping structure; (10) Push the nickel plate into the high-temperature flow line: after the sintering ceramic products are put into the nickel plate, the cylinder E pushes the nickel plate through the high-temperature conveying plate to the high-temperature flow line, and the high-temperature flow line sends the nickel plate into the sintering furnace.

10. The automatic feeding and discharging method of the spark plug ceramic sintering furnace automatic feeding and discharging machine according to claim 9, characterized in that: During the process of placing the sintered ceramic products into the plate, the right servo motor A rotates to drive the product seat to step, the step distance is 21MM each time, the mechanical hand takes, carries and places the products 4 times repeatedly, and one product placement is completed.
