Grafting device and grafting method based on UV adhesive

A grafting device based on UV (Ultraviolet Rays) adhesive, comprising a workbench, a transfer mechanism, a seedling loading mechanism, a cutting mechanism, an adhesive spraying mechanism, a curing mechanism and a seedling unloading mechanism,

• wherein the transfer mechanism, the seedling loading mechanism, the cutting mechanism, the adhesive spraying mechanism, the curing mechanism and the seedling unloading mechanism are sequentially arranged on the workbench;
• a seedling loading station, an adhesive spraying station, a curing station and a seedling unloading station are arranged in turn along a circumferential direction of the transfer mechanism;
• the seedling loading mechanism and the cutting mechanism are arranged at the seedling loading station;
• the adhesive spraying mechanism is arranged at the adhesive spraying station;
• the curing mechanism is arranged at the curing station;
• the seedling unloading mechanism is arranged at the seedling unloading station;
• at the seedling loading station, the seedling loading mechanism is configured for bearing a rootstock and a scion, the transfer mechanism is configured for receiving and fixing the rootstock and the scion, and the cutting mechanism is configured for cutting the rootstock and the scion;
• the transfer mechanism is configured for moving the rootstock and the scion located at the seedling loading station to the adhesive spraying station, and abutting the rootstock against the scion to obtain a grafted seedling;
• at the adhesive spraying station, the adhesive spraying mechanism is provided with a spray valve, and the adhesive spraying mechanism is configured for spraying UV adhesive on a periphery of a joint portion of the rootstock and the scion;
• the transfer mechanism is configured for transferring the grafted seedling located at the adhesive spraying station to the curing station;
• at the curing station, the curing mechanism is configured for curing the UV adhesive sprayed on the grafted seedling;
• the transfer mechanism is configured for transferring the grafted seedling located at the curing station to the seedling unloading station;
• at the seedling unloading station, the seedling unloading mechanism is configured for performing a seedling unloading treatment on the grafted seedling;
• the transfer mechanism is provided with a plurality of transfer units, and each of the plurality of transfer units comprises a rootstock clamping assembly and a scion clamping assembly;
• the rootstock clamping assembly and the scion clamping assembly are arranged side by side;
• the rootstock clamping assembly is movable between a first position and a second position;
• under a condition that the rootstock clamping assembly is at the first position, the rootstock clamping assembly is configured to get away from the scion clamping assembly, and the rootstock clamping assembly and the scion clamping assembly are configured to be matched with the seedling loading mechanism to clamp and fix the rootstock and the scion;
• and
• under a condition that the rootstock clamping assembly is at the second position, the rootstock clamping assembly is configured to get close to the scion clamping assembly for abutting the rootstock against the scion and clamping the grafted seedling.
