Claim 0:
1. A flexible dot matrix bonding apparatus for a disk-type planar component, wherein the flexible dot matrix bonding apparatus for the disk-type planar component comprises a substrate, connecting rods and an auxiliary support;
the trimming threaded holes are circumferentially and uniformly distributed in the substrate, mounting holes are circumferentially and uniformly distributed at an edge of an upper surface, and a groove is located at the middle; multiple arc grooves and threaded through holes are formed in the groove, and a sealing structure is arranged at an outer edge of the groove;
for the connecting rod, a hexagonal socket counterbore is formed on a bottom surface, and an external thread is formed at the bottom;
the auxiliary support contains multiple lug bosses, wherein arc silicone rubber plates are pasted on upper surfaces of the lug bosses, and a cross-sectional profile of the lug boss is identical to that of the arc silicone rubber plate;
when the disk-type planar component is machined, the connecting rods are fixed to the substrate firstly by using the threaded matching relationship; the connecting rods on the substrate are divided into two types, which respectively play roles in bonding and supporting the workpiece; the adhesive is coated on upper surfaces of the connecting rods which play the role in bonding, and circular silicone rubber plates are pasted on upper surfaces of the connecting rods which play the role in auxiliary support, to form a dot matrix clamping apparatus; the disk-type planar component to be machined is placed on a combined dot matrix clamping apparatus, and after the adhesive is cured, the height of the connecting rods which play the role in auxiliary support is adjusted until the circular silicone rubber plate thereon contacts a clamping surface of the disk-type planar component; and
when the disk-type planar component is disassembled, the bonding apparatus and the disk-type planar component that are bonded to each other are firstly placed on a heating platform, and the adhesive between the connecting rod and the disk-type planar component is melted; and subsequently, the combined structure is placed on the auxiliary support, and the lug boss on the auxiliary support penetrates through the arc groove on the substrate, wherein the arc silicone rubber plate thereon contacts the clamping surface of the disk-type planar component, and then the machined disk-type planar component is jacked up, thus realizing that the workpiece is taken out without damage.
