[0021] Example 1:

[0022] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a metal surface treatment coating device, including a coating box 1, a connecting plate 2 inside the coating box 1, a support plate 3 fixedly connected to the top outer surface of the connecting plate 2, two vertical plates 4 fixedly connected to the top outer surface of the support plate 3, a support shaft 7 rotatably passing through the two vertical plates 4, a first motor 5 fixedly mounted on the outer surface of one of the vertical plates 4, the output end of the first motor 5 fixedly connected to the support shaft 7, a fixing frame 6 fixedly sleeved on the outer surface of the support shaft 7, two sets of vertical plates fixedly connected to the top and bottom outer surfaces of the fixing frame 6, a first electric push rod 8 fixedly mounted on the outer surface of the vertical plate, an inverted L-shaped plate 9 fixedly mounted on the output end of the first electric push rod 8, a second electric push rod 10 fixedly mounted on the outer surface of the inverted L-shaped plate 9, and a second electric push rod 10 fixedly mounted on the output end of the second electric push rod 10. Specifically, the vacuum suction cups 11, based on the size of the metal parts, are operated by the first electric push rod 8 below. The first electric push rod 8 drives the two vacuum suction cups 11 to move to a flat position corresponding to the size of the metal parts. Then, the two sets of vacuum suction cups 11 below fix the parts, and then the metal parts are sprayed. After the spraying is completed, the first electric push rod 8 and the second electric push rod 10 above operate. The first electric push rod 8 moves the vacuum suction cups 11 above the metal parts, and the second electric push rod 10 drives the vacuum suction cups 11 to contact the top of the metal parts. Then, the first motor 5 drives the support shaft 7 to rotate the fixing frame 6, thereby flipping the metal parts and coating the other side of the metal parts, thus improving the coating efficiency of the metal parts.

[0023] In this embodiment, a rotating shaft is rotatably connected to the inner top surface of the coating box 1, and a second motor 14 is fixedly installed on the outer top surface of the coating box 1. The output end of the second motor 14 is fixedly connected to the rotating shaft. A half gear 13 is fixedly sleeved on the outer surface of the rotating shaft. A rack 15 is movably meshed on the outer surface of the half gear 13. A fixing strip 12 is fixedly connected to the outer surface of the rack 15. Specifically, when the second motor 14 works, it drives the half gear 13 to rotate. When the half gear 13 meshes with the rack 15, it drives the rack 15 to move, and the rack 15 drives the fixing strip 12 to move.

[0024] In this embodiment, a lead screw 19 is rotatably connected to the inner rear surface of the coating box 1, and a third motor 20 is fixedly installed on the outer rear surface of the coating box 1. The output end of the third motor 20 is fixedly connected to the lead screw 19, and a threaded plate 21 is threadedly connected to the outer surface of the lead screw 19. A connecting plate 2 is fixedly connected to the outer surface of the threaded plate 21. Specifically, when the spraying is completed, the third motor 20 works, drives the lead screw 19 to rotate, and the lead screw 19 drives the threaded plate 21 to move, conveying the sprayed metal parts to the outside of the coating box 1.

[0025] In this embodiment, a third electric push rod 16 is fixedly installed on the bottom outer surface of the fixing strip 12, and a nozzle 17 is fixedly installed at the output end of the third electric push rod 16. The nozzle 17 is connected to the output end of an external material pump. Specifically, during spraying, the height of the nozzle 17 is adjusted by the third electric push rod 16, and the paint is transported to the nozzle 17 and sprayed out by the external material pump.

[0026] In this embodiment, a sliding plate is fixedly connected to the top outer surface of the rack 15, and two support blocks are fixedly connected to the top inner surface of the coating box 1. A spring 18 is fixedly connected between the sliding plate and the support blocks. Specifically, when the rack 15 moves, it drives the sliding plate to move, and the sliding plate causes the spring 18 to deform. When the rack 15 is not under force, the elastic force of the spring 18 causes the rack 15 to return to its original position.

[0027] In this embodiment, a slide rod is fixedly connected to the inner surface of the coating box 1 near the top. The slide plate is movably sleeved on the outer surface of the slide rod, and the spring 18 is sleeved on the outside of the slide rod. Specifically, when the rack 15 moves, the slide plate slides on the outer surface of the slide rod, so that the rack 15 moves in a stable straight line, and the slide rod limits the spring 18 to prevent the spring 18 from tilting.

[0028] In this embodiment, a guide rod is fixedly connected to the bottom of the inner surface of the coating box 1, and the threaded plate 21 is movably sleeved on the outer surface of the guide rod. Specifically, when the lead screw 19 rotates, it drives the threaded plate 21 to move, so that the threaded plate 21 slides on the outer surface of the guide rod. The guide rod guides the movement of the threaded plate 21, preventing the threaded plate 21 from rotating with the lead screw 19.

[0029] Working Principle: When using this invention, the door is opened, and the parts to be coated are fixed. During fixing, the first electric push rod 8 below moves two vacuum suction cups 11 to a flat position corresponding to the size of the metal parts, according to the size of the metal parts. Then, the two sets of vacuum suction cups 11 below fix the parts, and then the metal parts are sprayed. After the spraying is completed, the first electric push rod 8 and the second electric push rod 10 above move the vacuum suction cups 11 above the metal parts. The second electric push rod 10 drives the vacuum suction cups 11 to contact the top of the metal parts. Then, the first motor 5 drives the support shaft 7 to rotate the fixing frame 6, thereby flipping the metal parts and coating the other side of the metal parts, thus improving the coating efficiency of the metal parts.

[0030] During spraying, the height of the nozzle 17 is adjusted by the third electric push rod 16, and the paint is delivered to the nozzle 17 by an external pump. The second motor 14 operates, driving the half gear 13 to rotate. When the half gear 13 meshes with the rack 15, it moves the rack 15, which in turn moves the fixing bar 12, causing the nozzle 17 to move to one side and deforming the spring 18. When the half gear 13 disengages from the rack 15, the spring 18 returns to its original position and moves the rack 15 to the other side. This allows the nozzle 17 to reciprocate within a certain range during the rotation of the second motor 14, increasing the spraying area and improving the uniformity of the nozzle 17.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
