5. The metal parts surface spraying equipment as described in claim 3, characterized in that, The hole spraying component (88) includes a paint delivery pipe (881) and a pusher blade (882) fixedly installed on the outside of the paint delivery pipe (881). The pusher blade (882) is located inside the closed cover (87). The paint delivery pipe (881) is fixedly connected to the air guide tube (884) through a connecting piece (883). The air guide tube (884) is inserted into the limiting groove (872) and is movably connected to the closed cover (87). A distribution hood (885) is provided inside the outlet end of the air guide tube (884). The distribution hood (885) is cone-shaped. A support rod (886) is provided inside the air guide tube (884) at the outlet end of the distribution hood (885). An air guide cone (887) is provided at the end of the support rod (886) away from the air guide tube (884). The air guide cone (887) and the air guide tube (884) form an outward-sloping air outlet, which facilitates the cleaning and blowing out of the inner wall of the perforation (101).

6. The metal parts surface spraying equipment as described in claim 5, characterized in that, A spray pipe (889) is provided on the outer side of the end of the paint delivery pipe (881). The spray pipe (889) passes through the air guide tube (884). A bearing (888) is provided on the inner side of the end of the paint delivery pipe (881) away from the spray pipe (889). The paint delivery mechanism is fixedly connected to the closed cover (87). A first sensor (8841) is provided on the outer side of the end of the air guide tube (884). A second sensor (8842) is provided on the air guide tube (884) on one side of the spray pipe (889).

7. A method for implementing the metal parts surface spraying equipment as described in claim 6, characterized in that, Includes the following steps: Step 1: When it is necessary to spray paint on a metal part (10) with smooth perforations, and the perforations need to be sprayed, the second robotic arm (3) drives the perforation spraying mechanism (8) to move to the front of the corresponding perforation. Step 2: Start the third small motor (82) to drive the first rack (83) to move forward, thereby pushing the hole spraying component (88) to move into the hole. When the first sensor (8841) senses it, the air duct (86) sends air into the sealed cover (87), thereby driving the pusher blade (882) to rotate. The pusher blade (882) then drives the paint delivery pipe (881) to rotate. At this time, the hole spraying component (88) rotates as a whole. At the same time, the gas flows out from the air outlet (871) and enters the air guide barrel (884). After being concentrated by the collection cover (885), it is sprayed out from the air outlet formed by the air guide cone (887) and the air guide barrel (884) and rotates, thereby cleaning the dust inside the perforation (101). Step 3: When the second sensor (8842) senses the coating, the coating delivery mechanism delivers the coating and sprays it out from the spray pipe (889). It also cleverly utilizes the rotation of the air guide tube (884) to spray the coating on the inside of the perforation (101). Step 4: After the hole spraying is completed, the first robotic arm (1) and the second robotic arm (3) are started at the same time to drive the first panel spray gun (2) and the second panel spray gun (4) to spray the surface of the metal parts (10).
