[0023] like Figures 1-4 The illustrated planar conveyor small aluminum part powder coating device includes a coating chamber 1, a conveyor belt 2 for conveying workpieces inside the coating chamber 1, a coating device 3 for powder coating workpieces inside the coating chamber 1, a tooling positioning frame 4 on the conveyor belt 2, and a tooling fixture 51 for positioning and placing workpieces detachably connected to the tooling positioning frame 4; the tooling fixture 51 includes a connecting frame 5 and a plurality of clamping members 6 spaced apart on the connecting frame 5, wherein the clamping member 6 has two spring pieces 7, and the two spring pieces 7 are in an expanded state that is relatively far apart in the initial state without external force, and two or more protrusions 9 extending on each spring piece 8 that can abut against the inner cavity sidewall of the workpiece.

[0024] Specifically, a small aluminum workpiece is covered by two spring clips of a clamping component, so that the two spring clips of the clamping component are located inside the cavity of the aluminum workpiece. The elastic deformation of the spring clips keeps the protrusions on them tightly against the side wall of the inner cavity of the workpiece. In this way, multiple protrusions tightly abut against the periphery of the inner cavity of the workpiece, realizing the clamping and positioning of the aluminum workpiece. The elastic deformation of the spring clips also facilitates the clamping, placement, or removal of the aluminum workpiece. Furthermore, the point contact between the protrusions and the side wall of the inner cavity of the workpiece effectively reduces the clamping contact area between the protrusions and the workpiece, thereby effectively improving the powder coating effect of the small aluminum workpiece.

[0026] Specifically, the first linear moving platform is a relatively mature existing technology, which can drive the first powder spraying gun to move back and forth along the X-axis. The corresponding conveyor belt conveys along the Y-axis, thus satisfying the powder spraying of small aluminum parts on the conveyor belt. The first powder spraying gun can be connected to an external powder supply device for powder supply. The powder supply device is a relatively mature existing technology, and its structure and principle will not be described in detail here. It can be used to supply powder to the first powder spraying gun.

[0027] Furthermore, the spraying device 3 also includes a second linear moving platform 12 located below the conveyor belt 2 inside the spraying chamber 1, and a plurality of second powder spraying guns 13 located at the moving end of the second linear moving platform 12. The powder outlet of the second powder spraying guns 13 is arranged upward, and the moving direction of the moving end of the second linear moving platform 12 is perpendicular to the conveying direction of the conveyor belt 2.

[0028] Specifically, the second linear moving platform is a relatively mature existing technology, which can drive the second powder spraying gun to move back and forth along the X-axis. The corresponding conveyor belt is conveyed along the Y-axis, thus satisfying the powder spraying of small aluminum parts on the conveyor belt. The first and second powder spraying guns are respectively distributed on the upper and lower sides of the aluminum parts to meet the requirement of synchronous powder spraying on the upper and lower sides of the aluminum parts. The second powder spraying gun can be connected to an external powder supply device for powder supply. The powder supply device is a relatively mature existing technology, and the powder supply structure and principle will not be described in detail here. It only needs to meet the requirement of supplying powder to the second powder spraying gun.

[0029] Furthermore, a powder return box 14 for collecting sprayed powder is provided at the bottom of the spraying chamber 1. Further, several exhaust pipes 15 are installed inside the spraying chamber 1 below the conveyor belt 2. These exhaust pipes 15 are connected to the powder return box 14 via pipes, and an exhaust device 16 is connected to the pipes to drive the sprayed powder in the exhaust pipes 15 to the powder return box 14. Specifically, the exhaust device is a relatively mature existing technology, and its structural principle will not be described in detail here. The combination of the exhaust device, the powder return box, and the exhaust pipes satisfies the need for powder recovery within the spraying chamber.
