The second rack is arranged on the second frame, The second motor is arranged on the third frame and connected to the second gear. The second gear is arranged on the third frame through the second motor and is engaged with the second rack. The primary horizontal movement control unit controls the second motor to drive the second gear to rotate, thereby causing the third frame to move horizontally.

5. The automatic transfer device for glue spraying according to claim 1, characterized in that: in, The transfer control unit includes a secondary horizontal movement control unit, The horizontal movement mechanism further includes a slide driving unit, The skateboard driving unit includes a screw rod and a third motor, The screw comprises a screw shaft and a nut seat, The screw shaft is connected to the third motor. The nut seat is arranged on the slide and connected to the screw shaft. The secondary horizontal movement control unit controls the third motor to drive the screw to rotate, thereby causing the slide to move horizontally.

6. An automatic transfer method for spraying glue, implemented using the automatic transfer device for spraying glue according to any one of claims 1 to 5, characterized in that: The following steps are involved: Step S1-1: Before glue spraying, the transfer control unit first controls the vertical drive unit to drive the second frame to move vertically and adjust the height of the supporting arm; Step S1-2, the transfer control unit controls the horizontal drive unit to drive the third frame to move horizontally toward the storage device, so that the supporting arm reaches below the target tray to be picked up; Step S1-3, the transfer control unit controls the vertical drive unit to drive the second frame to rise, and the supporting arm lifts the tray to separate the tray from the storage device; Step S1-4, the transfer control unit controls the horizontal drive unit to drive the third frame to move horizontally in a direction away from the storage device, so that the supporting arm retracts; Step S1-5, the transfer control unit controls the rotation drive unit to drive the support arm to rotate; Step S1-6, the transfer control unit controls the horizontal drive unit to drive the third frame to move horizontally toward the glue spraying device, so that the supporting arm reaches the glue spraying device; Step S1-7, the transfer control unit controls the vertical drive unit to drive the second frame to descend, so that the tray is separated from the supporting arm and supported by the glue spraying device; In step S1-8, the transfer control unit controls the horizontal drive unit to drive the third frame to move horizontally in a direction away from the glue spraying device, so that the supporting arm retracts.

7. The automatic transfer device for glue spraying according to claim 6, characterized in that: Also includes: Step S2-1: After the glue spraying is completed, the transfer control unit first controls the vertical drive unit to drive the second frame to move vertically and adjust the height of the supporting arm; Step S2-2, the transfer control unit controls the horizontal drive unit to drive the third frame to move horizontally toward the glue spraying device, so that the supporting arm reaches below the target pallet to be picked up; Step S2-3, the transfer control unit controls the vertical drive unit to drive the second frame to rise, and the supporting arm lifts the tray to separate the tray from the glue spraying device; Step S2-4, the transfer control unit controls the horizontal drive unit to drive the third frame to move horizontally in a direction away from the glue spraying device, so that the supporting arm retracts; Step S2-5, the transfer control unit controls the rotation drive unit to drive the support arm to rotate; Step S2-6, the transfer control unit controls the horizontal drive unit to drive the third frame to move horizontally toward the storage device, so that the supporting arm reaches the storage device; Step S2-7, the transfer control unit controls the vertical drive unit to drive the second frame to descend, so that the tray is separated from the supporting arm and supported by the storage device; In step S2-8, the transfer control unit controls the horizontal driving unit to drive the third frame to move horizontally in a direction away from the glue spraying device, so that the supporting arm retracts.
