3. The spray device of claim 1, wherein the spray assembly includes a first nozzle oriented in a direction same as the direction of extension of the drive assembly and a second nozzle oriented at an angle to the direction of extension of the drive assembly;
the controller is used for simultaneously starting the first nozzle and the second nozzle when the transmission assembly drives the spraying assembly to move to a preset position;
the controller is also used for closing the first nozzle after the first nozzle and the second nozzle are started for preset time.
4. The spray device of claim 3, wherein the spray assembly further comprises a feed tube in communication with the first nozzle and the second nozzle, the feed tube having a feed inlet and a compressed air port, the feed inlet being configured to couple to a feed structure, the compressed air port being configured to couple to a compressed air motor.
5. The spray device of claim 4, wherein said controller is further configured to activate said air compressor to purge said spray assembly prior to said spray assembly moving to said preset position.
6. The spray device of claim 1 further comprising a distance detection unit mounted on said drive assembly, said distance detection unit being electrically connected to said controller;
the distance detection unit is used for detecting a first distance and a second distance of the spraying component relative to two sides of the inner surface;
the controller is used for controlling the transmission assembly to drive the spraying assembly to move relative to the inner surface of the workpiece according to the first distance and the second distance, so that the first distance and the second distance are kept equal.
7. The spray coating device of claim 6 wherein said controller compares said first distance with said second distance, and when said first distance is not equal to said second distance, said controller controls said transmission assembly to move said spray coating assembly to a side having a greater distance, such that said first distance is equal to said second distance.
8. The coating apparatus of claim 1 wherein the drive assembly includes a first drive member and a second drive member, the first drive member being connected to the second drive member, the second drive member being connected to the coating assembly, the first drive member being configured to move the coating assembly in a first direction via the second drive member, the second drive member being configured to move the coating assembly in a second direction, the second direction extending in a direction of elongation of the workpiece, the first direction being perpendicular to the second direction.
9. The spray device of claim 8 wherein the drive assembly further comprises a connecting rod connected to the first drive portion, the connecting rod for connection to an external element to secure the drive assembly.
10. The spray coating device of claim 1 further comprising a dust guard housing, wherein said dust guard housing is disposed adjacent to said drive assembly, said dust guard housing having a dust guard opening, said dust guard opening being adapted to be connected to a dust collection device for collecting impurities generated by said spray coating assembly during spraying.
