Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, and in particular to a powder coating detection device. Background Technology

[0002] Powder coating is a solid coating that exists in powder form and is typically applied to the surface of a workpiece via electrostatic spraying. During electrostatic spraying, the spray gun uses high-voltage static electricity to charge the powder particles and move them towards the grounded workpiece, achieving uniform deposition of the powder coating. This type of coating features good film performance, strong adhesion, and corrosion resistance, and is widely used in construction, home appliances, hardware, and other fields. Before powder coating products leave the factory, simulated spraying tests are usually conducted to check the powder adhesion and color performance after spraying, in order to determine whether the quality of the powder bonding meets the actual usage requirements.

[0003] However, existing spraying inspection devices generally have the following drawbacks: First, the existing main spray pipe has a simple structure and a fixed length, which cannot meet the size requirements of the spraying system. This results in a difference between the spraying effect during the inspection process and the actual application, and cannot accurately reflect the bonding effect and color performance of the coating in the final application scenario. Second, during the inspection process, the sprayed workpiece is usually fixed by hanging it with wire. After the spraying is completed, the product needs to be removed and compared with the sample to detect the spraying effect, which is inconvenient to operate. Utility Model Content

[0004] This invention proposes a powder coating detection device to solve the problems mentioned in the background art, such as the fixed length of the main spray pipe, the inability to simulate the actual spraying effect, and the inconvenience of operation due to the need to remove the workpiece for comparison.

[0035] See Figures 1-3 A powder coating detection device, comprising:

[0036] A bracket 1 has a support plate 101 on top, and a rotatable spraying platform 12 is mounted on the support plate 101. The workpiece 5 is mounted on the spraying platform 12, and rotates when the spraying platform 12 rotates. A movable platform 15 is movably mounted on the bracket 1, and its direction of movement is perpendicular to the rotation axis of the spraying platform 12. A spray gun 6 is mounted on the movable platform 15 and configured to adjust the distance between the spray gun 6 and the workpiece 5. A paint can 8 is located below the bracket 1. A main spray pipe 9 is connected at one end to the spray gun 6 and at the other end to the paint can 8. Guided by the guide rod 7, the main spray pipe 9 can be precisely positioned. The connector ensures quick replacement of the spare spray pipe 11. The spray pipe frame 10 provides stable support. The overall structure works in concert to improve the uniformity and efficiency of spraying.

[0037] In this example, a protective cover 3 is also included, which is installed on one side above the bracket 1. The spraying platform 12 and the workpiece 5 are located inside the protective cover 3. Multiple spotlights 2 capable of emitting different colors are installed above the protective cover 3.

[0038] Specifically, a rectangular support plate 101 is welded on the top of the bracket 1. A rotatable spraying platform 12 is mounted on the center of the support plate 101 via bearings and shafts. When the platform is driven to rotate by a servo motor, it synchronously drives the workpiece 5 to rotate at a uniform speed.

[0039] Specifically, the moving platform 15 is mounted on the top crossbeam 14 of the bracket 1, and its moving direction is spatially perpendicular to the rotation axis of the spraying platform 12. The moving platform 15 is equipped with a spray gun 6. The moving platform 15 slides along the guide rod 7 to precisely adjust the distance between the spray gun 6 and the workpiece 5 to ensure uniform spraying coverage. More specifically, the moving platform 15 can be moved by a motor and a lead screw, or screws can be installed on the side of the moving platform 15. After the moving platform 15 moves to the designated position, the moving platform 15 can be fastened by tightening the screws.

[0040] Specifically, the main spray pipe 9 is a rubber hose, one end of which is connected to the spray gun 6, and the other end is connected to the discharge port at the top of the paint can 8 by a threaded connection. The outer shell of the paint can 8 has a buckle 801 for storing the main spray pipe 9, and the main spray pipe 9 is locked in the U-shaped groove of the buckle 801.

[0041] Specifically, the upper surface of the spraying platform 12 is equipped with two uprights 13, and a crossbeam 14 is connected to the top of the uprights 13. At least two steel wire ropes 4 are slidably connected to the crossbeam 14. The workpiece 5 is connected to the lower end of one of the steel wire ropes 4. In this example, there are two steel wire ropes 4, one for mounting the workpiece 5 and the other for mounting a sample. This sample is a standard finished product after spraying and is mainly used for spraying comparison. Specifically, the crossbeam 14 has a groove arranged along its length, and a limit slider is installed in the groove. When the steel wire rope 4 is adjusted to the appropriate position, the limit slider is moved and the screw is tightened to ensure that the steel wire rope 4 will not slip during operation. After the spraying is completed, the workpiece 5 and the steel wire rope 4 can be moved to one side of the crossbeam 14, and the sample can be suspended on another steel wire rope 4. The sample is then illuminated by spotlights 2 of different colors to check whether the product is consistent with the sample. More specifically, in this example, there are three spotlights 2, which can emit white light, red light and blue light respectively, for light detection under different colors of illumination, thus further improving the quality of detection.

[0042] Specifically, a nozzle frame 10 is welded to the side column of the bracket 1, and a spare nozzle 11 is suspended on the nozzle frame 10. The spare nozzle 11 is connected to the spray gun 6 and the main nozzle 9 respectively through quick-change connectors. The total length of the main nozzle 9 can be adjusted by adding or removing the spare nozzle 11. With this design, the length of the main nozzle 9 during the testing process can be set according to the actual spraying conditions, thereby improving the consistency between testing and actual operation.

[0043] Specifically, the system includes a platform baffle 16 located at the end of the guide rod 7 of the support 1. When the moving platform 15 moves to its travel limit position, it can abut against the platform baffle 16 to protect the equipment from damage, prevent over-limit operation, and ensure operational safety. The spray gun 6 is equipped with a fine-tuning knob to precisely control the spraying angle. Combined with the servo motor driving the spraying platform 12 to rotate at a uniform speed, it achieves uniform coverage from multiple angles.

[0044] Specifically, two guide rods 7 are arranged in parallel on the bracket 1, and the moving platform 15 is slidably connected to the guide rods 7 via linear bearings. The precise fit between the guide rods 7 and the linear bearings ensures smooth and high-precision movement, reduces frictional loss, and extends the service life of the equipment. Screws are provided on the side wall of the moving platform 15, and the second limit screw can be adjusted to fix the moving platform 15 when it moves to the designated position. At the same time, the parallel layout of the guide rods 7 enhances the stability of the overall structure, improves the precision and reliability during the spraying process, and further ensures the consistency and efficiency of the spraying effect.
