[0002] In industrial production, particularly in the automotive parts, appliance housings, electronic product casings, and toy industries, surface coating is a common process. Traditional coating equipment, especially automated coating equipment for small and medium-sized workpieces, typically employs a single-station design. The operation process usually involves: manual or robotic arms loading the workpiece onto the equipment for coating; after coating, the workpiece is unloaded manually or by robotic arms, and then new workpieces are loaded manually or by robotic arms for the next round of coating. This technical solution results in significant idle waiting time, leading to low equipment utilization and limited output per unit time. Utility Model Content

[0003] To address the problems of traditional spraying equipment, which typically employs a single-station design, resulting in low equipment utilization and limited output per unit time, this application provides a multi-axis reciprocating spraying device.

A revolution drive assembly is located below the machine body and the gantry module structure, connected to a conversion plate. The conversion plate is parallel to the Y-axis, and fixtures are provided at both ends of the conversion plate for fixing workpieces. The revolution drive assembly drives the conversion plate to rotate, causing the positions of the two ends of the conversion plate to interchange.

[0005] Preferably, the two ends of the conversion plate are further provided with a rotation drive component, which is connected to the fixture to drive the fixture to rotate.

[0010] In summary, this application includes at least one of the following beneficial technical effects:

[0011] 1.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Reference Figure 1-3 A multi-axis reciprocating spraying device includes a body serving as a basic support platform. A gantry module structure 2 is mounted on the body. A spray gun 3 is driven and connected to the gantry module structure 2. The gantry module structure 2 includes an X-axis linear module 21, a Y-axis linear module 22, a Z-axis linear module 23, and a connecting frame 24. There are two X-axis linear modules 21, which are parallel and symmetrically arranged and are parallel to the X-axis direction. The Y-axis linear module 22 is parallel to the Y-axis direction, and its two ends are respectively connected and fixed to the moving parts of the two X-axis linear modules 21. The Z-axis linear module 23 is parallel to the Z-axis direction and is fixed to the moving part of the Y-axis linear module 22. The connecting frame 24 is connected to the moving part of the Z-axis linear module 23. The spray gun 3 is hinged to the connecting frame 24 and locked to the connecting frame 24 by bolts. In the above structure, the spray gun 3 is driven to reciprocate along the X-axis by two X-axis linear modules 21, the Y-axis linear module 22 and the Z-axis linear module 23, the Y-axis linear module 22 drives the Z-axis linear module 23 to reciprocate along the Y-axis, and the Z-axis linear module 23 drives the spray gun 3 to reciprocate along the Z-axis. The reciprocating movement of the spray gun 3 along the X, Y and Z axes results in a large spraying range, making it suitable for spraying complex workpieces and ensuring high equipment compatibility. The spray gun 3 is hinged to the connecting frame 24 and locked to the connecting frame 24 with bolts to adjust the angle of the spray gun 3, so that the spray gun 3 can be adapted to different types of workpieces and further improve the compatibility of the equipment. Specifically, the spray gun 3 includes a gun body 31 and a connecting strip 32 connected to the gun body 31. One end of the connecting strip 32 is provided with a C-shaped groove 321. The connecting frame 24 is provided with a hinge shaft 241 that passes through the C-shaped groove 321. The bolt connects to the opening of the C-shaped groove 321. By tightening the bolt, the groove wall of the C-shaped groove 321 deforms and clamps the hinge shaft 241 to lock and fix the connecting strip 32 to the hinge shaft 241. Loosening the bolt allows the connecting strip 32 to swing around the hinge shaft 241 to adjust the angle of the gun body 31.

[0020] Reference Figure 3 Furthermore, the X-axis linear module 21, Y-axis linear module 22, and Z-axis linear module 23 are all lead screw modules, which have high displacement accuracy and stable operation, making it easy to ensure the accuracy of spraying.

[0021] Reference Figure 1 and Figure 3 A revolution drive assembly 4 is installed below the machine body 1 and the gantry module structure 2. The revolution drive assembly 4 is connected to a conversion plate 5. The conversion plate 5 is located below and in the middle of the two X-axis linear modules 21. The conversion plate 5 is parallel to the X-axis linear modules 21. Fixtures 6 are installed at both ends of the conversion plate 5, and the workpiece is fixed by the fixtures 6. The revolution drive assembly 4 drives the conversion plate 5 to rotate, so that the positions of the two ends of the conversion plate 5 are interchanged. The fixtures 6 at both ends are interchanged between the spraying operation area and the loading and unloading operation area, so as to realize the parallel operation of workpiece spraying and loading and unloading, effectively reducing the equipment idle rate and improving the spraying efficiency.

[0022] Reference Figure 1 and Figure 3 Furthermore, the two ends of the conversion plate 5 are also provided with a self-rotation drive component 7. The self-rotation drive component 7 is connected to the fixture 6 to drive the fixture 6 to rotate. Through the self-rotation of the fixture 6, the spray gun 3 is driven to move along the composite trajectory of the X, Y and Z axes, which further realizes full coverage spraying of complex curved surfaces and makes the equipment more compatible.

[0023] Reference Figure 1 and Figure 3 Furthermore, the rotation drive assembly 7 includes a first cam divider 71 and a first servo motor 72. The output shaft of the first cam divider 71 is connected to the fixture 6, and the input shaft of the first cam divider 71 is connected to the first servo motor 72. The revolution drive assembly 4 includes a second cam divider 41 and a second servo motor 42. The output shaft of the second cam divider 41 is connected to the middle of the conversion plate 5, and the input shaft of the second cam divider 41 is connected to the second servo motor 42. The revolution and rotation are driven by the cam divider. The cam divider has high positioning accuracy, ensuring that the rotation trajectory of each batch of workpieces is consistent and reducing color difference.

[0024] The implementation principle of the multi-axis reciprocating spraying equipment disclosed in this application is as follows: During equipment operation, operators can load and unload workpieces at the non-spraying side station, while workpieces at the other side station are being sprayed by the spray gun 3. After spraying is completed, the second cam divider 41 drives the conversion plate 5 to rotate half a revolution, causing the sprayed workpiece to move to the loading / unloading side, while a newly loaded workpiece enters the spraying station. During this process, the gantry system continuously drives the spray gun 3 to move along a composite trajectory of X, Y, and Z axes, achieving full coverage spraying of complex curved surfaces in conjunction with workpiece rotation. The precise positioning characteristics of the cam divider ensure that the workpiece rotation angle is consistent each time, effectively eliminating the problem of coating color difference. This design, through a dual-station automatic conversion mechanism, completely overlaps the loading / unloading time with the spraying time, significantly improving equipment utilization and unit time productivity.
