8. An automatic punching processing method of a lyocell annular spinneret plate, comprising the automatic punching apparatus of claims 1-7, characterized by comprising the steps of:
s1, placing a single spinneret plate to be punched into an accommodating cavity formed between a supporting plate and a clamp bottom plate, and fixing a machining position of the spinneret plate in the accommodating cavity through a locking clamp pressing plate;
s2, adjusting the punching distance between the punching head and the spinneret plate, placing a cushion block between the buffer piece and the upper end face of the force transmission shaft base, and fixing the force transmission rod on a first fixing hole and a second fixing hole of the force transmission fixing plate to enable the force transmission rod to abut against the punching head, so that the position of the punching head is fixed and the minimum processing position between the punching head and the spinneret plate is achieved;
s3, moving the spinneret plate to the initial position of punching of the punching head, determining the number of punched holes and the number of punching turns through a control program, automatically punching the spinneret plate, finishing the first punching, taking down the spinneret plate after the first punching for grinding and polishing, and putting the processed spinneret plate into the accommodating cavity for preparing for the second punching;
s4, adjusting the position of a spinneret plate, enabling a CCD camera to obtain a first punching image on the spinneret plate, transmitting the center coordinate of each hole position to external control equipment, carrying out identification and analysis on the center coordinate of each hole position through the control equipment, comparing the coordinate of a punching head with the center coordinate of any hole position on the spinneret plate after the first punching, if the coordinates are inconsistent, adjusting the position of the spinneret plate, enabling the coordinate of the punching head to coincide with the center coordinate of any hole position, and if the coordinates are consistent, transmitting data to a punching mechanism, and enabling the punching head to align to the center of a hole under the coincident coordinates to carry out second punching;
s5, taking down the spinneret plate after the secondary punching, grinding and polishing again, placing the spinneret plate into a containing cavity, repeating the step S4, and finishing the third punching;
s6, after punching is finished, fixing the dowel bars on the first fixing hole and the third fixing hole of the dowel fixing plate, and enabling the dowel bars to be far away from the punching head, so that the position of the punching head is moved, the maximum distance between the punching head and a spinneret plate is ensured, and position interference with the punching head when the spinneret plate is taken out is avoided;
and S7, repeating the steps from S1 to S6 to process the second spinneret plate.
9. The automatic punching process of a lyocell ring spinneret according to claim 8, wherein: and the punching head punches the spinneret plate from inside to outside.
10. The automatic punching process of a lyocell ring spinneret according to claim 8, wherein: and hole sites between two adjacent inner parts and outer parts on the spinneret plate are arranged in a staggered manner.
