Description

Technical Field

[0001] This utility model relates to the field of 3D printed parts surface treatment technology, and in particular to a vibratory polishing machine for resin 3D printed parts. Background Technology

[0002] When using 3D printing technology to produce product shells and other structural components, surface textures and pixelation are inevitably present due to the molding principle of 3D printing, significantly impacting the product's appearance and feel. Traditionally, when using 3D-printed parts as exterior components, the surface is manually sanded to smooth out the textures. However, this method is prone to uneven sanding, leading to localized over-sanding, and sanding can leave irregular scratches on the surface. A more uniform matte surface requires sandblasting, but this is difficult to perform when the production site cannot handle the dust pollution from sandblasting. Furthermore, manual sanding and sandblasting are labor-intensive and result in a high defect rate. Utility Model Content

[0003] To address the aforementioned shortcomings, this invention provides a vibratory sander for resin 3D printed parts, which can sand a large number of 3D printed parts in batches, significantly reducing manual labor and largely solving the problem of dust pollution.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A vibratory sander for resin 3D printed parts, comprising:

[0006] The drive unit includes a chassis, a vibrator, and a control assembly. The vibrator is mounted on the upper surface of the chassis, and the control assembly includes a time relay and a controller located inside the chassis.

[0007] The grinding unit, located at the top of the drive unit, includes a rubber cup, with a temperature sensor passing through the bottom surface of the rubber cup and a liquid level sensor passing through the circumferential side surface of the rubber cup.

[0008] Furthermore, the top of the chassis has a top opening, and the vibrator includes a vibration motor installed inside the chassis. Its output end has a vibration rod located on the inner periphery of the top opening, and the upper end of the vibration rod has a swing block.

[0009] Furthermore, the lower end of the swing block is equipped with multiple buffer springs, and the bottom end of the buffer springs is fixed to the upper surface of the chassis.

[0010] Furthermore, the rubber cup is fixed to the upper end of the swing block.

[0011] Furthermore, the time relay includes a display screen mounted on one end of the chassis for displaying the remaining polishing time.

[0012] Furthermore, a temperature warning light and a liquid level warning light are also provided on one end of the chassis. The time relay, temperature warning light, and liquid level warning light are all electrically connected to the controller.

[0013] Furthermore, the polishing unit also includes a first cable and a second cable that pass through the upper surface of the chassis and are connected to the controller.

[0014] Furthermore, the temperature sensor is located at the upper end of the first cable, and the liquid level sensor is located at the upper end of the second cable.

[0015] Furthermore, the temperature sensor is equipped with a first mesh cover, and the liquid level sensor is equipped with a second mesh cover on its side.

[0016] The beneficial effects of this technical solution are as follows:

[0017] 1. It can process a large number of resin 3D printed parts in batches at the same time, and the sanding time of each batch is controlled by a time relay, so that the sanding degree of each batch is relatively stable. It can effectively remove surface textures and pixel textures. Since it is not sanded by hand, it is not easy to produce scratches, and it will not damage the product due to excessive sanding time.

[0018] 2. It can operate safely for a relatively long period of time without supervision. It can monitor abnormal conditions in real time through temperature and liquid level sensors, which can save a lot of manpower.

[0019] 3. No further sandblasting is required, and the abrasive and parts are placed inside the rubber cup for grinding, which reduces the likelihood of generating a large amount of dust pollution. Attached Figure Description

[0021] Figure 2 The overall perspective of the embodiments of this application is shown. Figure 2 . Detailed Implementation

[0022] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 1 , Figure 2The vibratory sander shown includes a drive unit 1 and a sanding unit 2 for resin 3D printed parts.

[0024] The drive unit 1 includes a housing 11 with a top opening 12 at its upper end. The drive unit 1 also includes a vibrator and a control component. The vibrator includes a vibration motor located inside the housing 11, and its output end has a vibration rod 13 located on the inner periphery of the top opening 12. The upper end of the vibration rod 13 has a swing block 14, and the lower end of the swing block 14 has multiple buffer springs 15. In this embodiment, there are four buffer springs 15. The bottom ends of the buffer springs 15 are fixed to the upper surface of the housing 11. The control component includes a time relay and a controller located inside the housing 11. The time relay includes a display screen 16 installed on one end of the housing 11 for displaying the remaining polishing time. In this embodiment, the controller uses a microcontroller. The control component also includes a communication module that can communicate with a remote terminal, such as a mobile phone, to set the polishing time and start a polishing program via an APP, i.e., start timing. One end of the housing 11 is also provided with a temperature warning light 17 and a liquid level warning light 18. The vibrator, time relay, communication module, temperature warning light 17, and liquid level warning light 18 are all electrically connected to the controller.

[0025] The grinding unit 2 is located on the upper end of the drive unit 1 and includes a rubber cup 21 fixed to the upper end of the sling block 14. The upper end of the rubber cup 21 has a material discharge port 22. The grinding unit 2 also includes a first cable 23 and a second cable 25 that pass through the upper end of the housing 11 and are connected to the controller. The upper end of the first cable 23 is provided with a temperature sensor that passes through the bottom end of the rubber cup 21. The temperature sensor is provided with a first mesh cover 24 and is a waterproof temperature sensor. The upper end of the second cable 25 is provided with a liquid level sensor 26 that passes through the periphery of the rubber cup 21. The side of the liquid level sensor 26 is provided with a second mesh cover 27. In this embodiment, both the first mesh cover 24 and the second mesh cover 27 are made of stainless steel.

[0026] Work style:

[0027] Abrasive and the part to be polished are placed in the rubber bowl 21, then water is added, and the controller starts the polishing program. The vibrator is activated, and the time relay starts timing according to the preset polishing time. In this embodiment, diamond is used as the abrasive.

[0028] During the polishing process: If the temperature sensor detects that the abrasive temperature is too high, exceeding the preset value, the temperature warning light 17 will light up, the time relay will pause the timing, and the controller will stop the vibrator from polishing. At this time, the abrasive will automatically wait for cooling, or the staff can use a fan or other equipment to cool it. The time relay will resume the timing, and the controller will continue the polishing, effectively preventing damage to the resin 3D printed parts. If the water evaporates and the liquid level drops below the preset value, the liquid level warning light 18 will light up, the time relay will pause the timing, and the controller will stop the vibrator from polishing. At this time, the staff can add water, the time relay will resume the timing, and the controller will continue the polishing.

[0029] Once the timer is complete, the grinding of that batch of parts is finished. The controller then stops the vibrator from grinding. By repeating the above steps, multiple batches of parts can be ground.

[0030] The above are only some of the embodiments listed in this application and are not intended to limit this application.
