Description

Technical Field

[0001] This utility model relates to the technical field of workpiece surface treatment equipment, specifically to a closed-type automatic powder cleaning machine. Background Technology

[0002] In fields such as metal processing and 3D printing additive manufacturing, residual powder often adheres to the surface of workpieces. Traditional powder removal equipment has the following drawbacks:

[0003] 1. Cleaning dead corners problem: In fixed ultrasonic cleaning equipment, the position of the workpiece is limited, and the ultrasonic energy cannot cover complex curved surfaces or deep groove areas, resulting in uneven powder cleaning.

[0004] 2. Low powder recovery rate: The open structure causes dust to escape, which not only pollutes the environment, but also the fact that the recovery device is not directly linked to the powder cleaning area can easily cause secondary accumulation of powder.

[0005] 3. Insufficient automation: It relies on manual adjustment of the workpiece angle, which is inefficient and cannot achieve continuous operation.

[0006] Existing technologies attempt to optimize the effect by increasing ultrasonic power or using multi-station designs, but they fail to resolve the systemic contradiction between multi-angle dust removal and closed-loop dust treatment, and their structural stability is insufficient.

[0007] Therefore, a closed-loop automatic powder cleaning machine is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figure 1-5As shown, this utility model provides a technical solution: a closed automatic powder cleaning machine, including a frame 1, with an ultrasonic generator 2 installed inside the frame 1; the ultrasonic generator 2 includes a box-type frame 20, with a mounting base 21 installed inside the box-type frame 20, the mounting base 21 being connected to the box-type frame 20 via a first rotating mechanism 3 and achieving vertical rotation; a turntable 22 is installed on the upper part of the mounting base 21, the turntable 22 being connected to the mounting base 21 via a second rotating mechanism 4 and achieving horizontal rotation; a workpiece bearing plate 23 is installed on the upper part of the turntable 22, and at least a pair of oppositely arranged ultrasonic generators 24 are provided on the surface of the workpiece bearing plate 23. The dual-degree-of-freedom powder cleaning method, through the combined motion of the vertically rotating first rotating mechanism and the horizontally rotating second rotating mechanism, exposes the workpiece to the ultrasonic wave range at multiple angles, eliminating the dead angle problem of traditional powder cleaning machines and improving cleaning uniformity. The symmetrical ultrasonic layout, with the oppositely arranged ultrasonic generators forming a counter-current resonance field, enhances the utilization rate of ultrasonic energy, improves powder stripping efficiency, and avoids residual accumulation caused by powder cleaning. The enclosed structure and box-type frame design effectively prevent dust from escaping while reducing noise pollution.

[0026] See Figure 2-5 As shown, the first rotating mechanism 3 includes a servo motor 30, a linkage 31, a first gear disk 32, a second gear disk 33, a first bearing 34, and a second bearing 35. The linkage 31 is connected to the output shaft of the servo motor 30, and its output shaft passes through the side plate of the box-type frame 20 and meshes with the first gear disk 32. The first gear disk 32 is movably sleeved outside the first bearing 34, which is connected to the side plate of the box-type frame 20. The end face of the first gear disk 32 is fixedly connected to the first connecting part 210 of the mounting base 21. The second gear disk 33 is movably sleeved outside the second bearing 35, which is connected to the side plate of the box-type frame 20. The end face of the second gear disk 33 is fixedly connected to the second connecting part 220 of the mounting base 21. It should be noted that the second gear disk 32 is used as a passive transmission mechanism. The purpose of setting the second gear disk 32 is to form a bidirectional support for the mounting base 21 and improve the stability of the rotation. The symmetrical design of the double gear disk and double bearing ensures the stability and load-bearing capacity of the mounting base 21 when it is vertically rotated, and reduces the interference of mechanical vibration on the ultrasonic operation. The first connecting part 210 and the second connecting part 220 on the mounting base 21 are synchronously driven by a symmetrical gear disk, which disperses torsional stress and extends the service life of the mechanism. Servo motor drive: precisely controls the flipping angle to adapt to the powder cleaning needs of workpieces with different shapes.

[0027] See Figure 3-4As shown, the second rotating mechanism 4 includes a servo motor 40, a linkage 41, a gear disk 42, and a bearing 43. The linkage 41 is connected to the output shaft of the servo motor 40, and its output shaft passes through the base plate of the mounting base 21 and meshes with the gear disk 42. The gear disk 42 is movably sleeved on the outside of the bearing 43, which is connected to the base plate of the mounting base 21. The end face of the gear disk 42 is fixedly connected to the turntable 22. Figure 3 As can be seen, a protective box 9 is provided outside the second rotating mechanism 4 to protect the servo motor 40 and the linkage 41, preventing the servo motor 40 from being directly exposed to the working environment. The independent servo motor 40 drives the gear disk 42, realizing 360° rotation of the turntable 22 in the horizontal plane without dead angles, forming a spatially coordinated powder cleaning path with the vertical flipping. This avoids the tedious operation of manually adjusting the workpiece. The bearing 43 is embedded in the base plate of the mounting base 21, saving longitudinal space and reducing the overall height of the equipment.

[0028] See Figure 2 As shown, it also includes a mobile powder recovery device 5 connected to the ultrasonic generator 2. The mobile powder recovery device 5 is installed inside the frame 1 and directly below the ultrasonic generator 2. The mobile recovery device 5 is directly integrated inside the frame 1, realizing the immediate collection and transfer of powder, reducing environmental pollution in the workshop. Moreover, the mobile recovery device 5 is located directly below the powder cleaning area, realizing a closed-loop process from powder stripping to collection, preventing secondary pollution.

[0029] See Figure 2-3 As shown, the bottom plate of the box-type frame 20 has an opening structure 200, and a powder recovery funnel 6 is fixedly connected to the bottom plate of the box-type frame 20 around the opening structure 200. The powder recovery funnel 6 is connected to the input valve body 8 of the mobile powder recovery device 5 through a pipe 7. Through the funnel effect of the opening structure 200 and the powder recovery funnel 6, powder scattering is prevented, and the recovery rate is increased to over 99%. The powder recovery funnel 6 is rigidly connected to the bottom plate of the box-type frame 20 to avoid loosening of the interface due to vibration. It should also be noted that, in addition to facilitating dust diversion and collection, the opening structure 200 also serves another purpose: to avoid the protective box 9, allowing the mounting base 21 to perform a vertical flipping trajectory within a limited space without causing the protective box 9 to collide.

[0030] See Figure 3-5 As shown, the workpiece support plate 23 is provided with several connecting holes 230 for fixed connection with the workpiece, and fixing holes 231 for fixed connection with the ultrasonic generator 24. The connecting holes 230 and fixing holes 231 are arranged in separate areas to meet the needs of both workpiece fixation and ultrasonic generator 24 positioning, and to accommodate workpieces of different sizes. Vibration transmission optimization and rigid fixing hole design ensure that ultrasonic energy is efficiently transmitted to the workpiece surface.

[0032] (a) Workpiece loading stage

[0033] The workpiece 10 to be processed is fixed to the workpiece support plate 23 through the connection hole 230, and the box frame 20 sealing door is closed.

[0034] (II) Powder Cleaning Stage

[0035] Parameter adaptation: Set preset parameters such as flip angle, vibration frequency, and power on the electronic display screen according to the shape of the workpiece.

[0036] Vertical flipping: Servo motor 30 drives the first gear disk 32 and synchronously drives the second gear disk 32, causing the mounting base 21 to flip 0-90° along the bearing axis, so that the workpiece is exposed to the ultrasonic action range from multiple angles, eliminating the traditional dead angle problem and improving cleaning uniformity.

[0037] Horizontal rotation: Servo motor 240 drives turntable 22 to rotate 360° on the horizontal plane through gear disk 242, synchronously triggering ultrasonic generator 24 to work.

[0038] (III) Powder Recovery Stage

[0039] The stripped powder falls into the powder recovery funnel 6 through the open structure 200 and is sucked into the mobile recovery device 5 through the pipe 7.

[0040] (iv) Workpiece Removal Stage

[0041] The dual rotating mechanism resets, the ultrasonic waves shut off, and the chamber door is opened to remove the workpiece.
