Technical Field

[0001] This utility model relates to the field of metal parts painting technology, specifically an automatic parts painting machine. Background Technology

[0002] Currently, metal parts used in industries such as automobiles and other machinery require personnel to remove and transport them to painting equipment for painting during production line processing. Painting can isolate metal parts from contact with water or oxygen, thereby preventing rusting, and can also increase the aesthetics of the metal surface and improve the overall visual effect of the product.

[0003] Currently used spray painting equipment generally consists of a spray painting mechanism and tooling. The parts that need to be painted need to be pre-loaded into the tooling by personnel for painting and then taken out, which is inefficient and not suitable for the smooth processing of production conveyor lines.

[0004] Based on this, this utility model designs an automatic paint coating machine for parts to solve the above problems. Summary of the Invention

[0028] Please see Figure 1-4 This utility model provides a technical solution: an automatic paint coating machine for parts, comprising: a main frame 1, a paint spraying mechanism, a conveying mechanism, and a lifting mechanism;

[0029] The lifting mechanism includes a top plate 6, a brake motor 11 fixed to the top of the top plate 6, a spool 12 rotatably connected to the top of the top plate 6, a stabilizing slide bar 7 slidably connected to the outer wall of the top plate 6, a linkage plate 10 fixed between the stabilizing slide bars 7, and a connecting line 13 disposed between the linkage plate 10 and the spool 12.

[0030] The conveying mechanism includes a roller conveyor belt 5 and two guide plates 14 disposed on the top of the roller conveyor belt 5;

[0031] One end of the stabilizing slide bar 7 is fixed with a connecting plate 8, and the connecting plate 8 is locked with a fastening bolt 9 between the roller conveyor belt 5;

[0032] The painting mechanism includes a paint nozzle 4, with the spraying end of the paint nozzle 4 facing the roller conveyor belt 5 of the conveying mechanism;

[0033] The painting mechanism, conveying mechanism, and lifting mechanism are all installed on the main frame 1. The main frame 1 houses the painting mechanism, conveying mechanism, and lifting mechanism together in the metal parts production line. The roller conveyor belt 5 of the conveying mechanism directly connects to the conveyor belt of the metal parts in the production line, so that the metal parts in the production line are sprayed with paint by the paint spray nozzles 4 of the painting mechanism in sequence. Two guide plates 14 in the conveying mechanism limit the movement of the metal parts as they pass through the roller conveyor belt 5, so that they are not easily deviated and affect the processing. The roller conveyor belt 5 can be height adjusted by the lifting mechanism before operation to adapt to the conveyor belts of more production lines. The stabilizing slide bar 7 in the lifting mechanism connects to the roller conveyor belt 5 through the cooperation of the connecting plate 8 and the fastening bolt 9. It can be disassembled for disassembly, assembly, maintenance, inspection, and cleaning of the roller conveyor belt 5, which improves the overall automation capability.

[0034] More preferably, the painting mechanism further includes two symmetrical first linear electric rails 2 and a second linear electric rail 3 disposed on the sliding part of the two first linear electric rails 2; the paint nozzle 4 is fixed to the sliding part of the second linear electric rail 3;

[0035] In the painting mechanism, the two first linear electric guides 2 are set vertically to control the second linear electric guide 3 to move up and down, thereby allowing the paint nozzle 4 to be adjusted up and down. The second linear electric guide 3 is set horizontally to control the paint nozzle 4 to move horizontally, making the paint nozzle 4 suitable for painting more metal parts.

[0036] In a further preferred embodiment, the first linear electric guide rails 2 are all fixed to the outer wall of the main frame 1, and the paint inlet end of the paint nozzle 4 is set facing upwards;

[0037] The first linear electric guide rail 2 is installed on the main frame 1 to assist the operation of the painting mechanism, while the paint nozzle 4 in the painting mechanism uses its upward-facing access end to connect to the paint supply system to ensure paint access and use.

[0038] A further preferred embodiment has a through hole on the outer wall of the top plate 6, through which the connecting line 13 passes and connects to the linkage plate 10 and the reel 12;

[0039] The through hole in the top plate 6 allows the connecting wire 13 to pass through, enabling the connecting wire 13 to better connect the connecting plate 8 and the reel 12 for transmission.

[0040] In a further preferred embodiment, the top plate 6 is fixed to the top of the main frame 1, and the drive end of the brake motor 11 is connected to one end of the reel 12.

[0041] The top plate 6 is installed at a high position on the main frame 1 for use, so that the installed brake motor 11 can control the rotation of the reel 12 at a high position to reel in and unload the connecting cable 13.

[0042] More preferably, two guide plates 14 are symmetrically arranged above the rollers of the roller conveyor belt 5;

[0043] The two guide plates 14 are designed to keep the metal parts within a certain range as they move on the roller conveyor belt 5, thus preventing them from shifting and affecting the processing.

[0044] A specific application of this embodiment is as follows: The main frame 1 is erected between the production conveyor lines, and the two ends of the roller conveyor belt 5 are respectively connected to the conveyor belts of metal parts. The height of the roller conveyor belt 5 can be adjusted according to its height. During adjustment, the brake motor 11 controls the reel 12 to rotate forward or backward to retract and extend the connecting line 13. Thus, the linkage plate 10 drives the stabilizing slide bar 7 and the roller conveyor belt 5 to move up and down, so as to quickly adapt to the production conveyor belts of more metal parts of greater height. When the roller conveyor belt 5 moves up and down, the stabilizing slide bar 7 helps it to avoid deviation and affect the docking. After docking, the metal parts conveyed by the production line can be directly transferred through the roller conveyor belt 5. At the same time, the paint spray nozzle 4 of the painting mechanism sprays paint on the metal parts that have passed through the roller conveyor belt 5.
