Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to dustproof structure technical field, more specifically, it relates to a dustproof structure of closed linear motor module. BACKGROUND
[0002] In the prior art, the material of the brush is usually soft, which prevents scratching the surface of the cover plate, but also makes it difficult to form sufficient pressure contact between the brush and the cover plate. Due to insufficient pressure, the cleaning effect of the brush on the dust on the surface of the cover plate during sliding is poor, and dust or particulate matter may remain.
[0003] In actual use, due to the influence of vibration in the working environment and external interference, the running state of the brush is easily disturbed, and intermittent problems may occur in the dustproof effect. This discontinuous cleaning method will directly affect the cleaning degree of the system, thereby affecting the overall precision and stability of the module. For high-precision equipment, even a small change in precision will have a significant adverse effect on the final processing result or motion control.
[0004] The existing dustproof structure lacks flexibility and convenience in design. During daily use or maintenance, when the dustproof structure needs to be folded or adjusted, the existing design often cannot conveniently achieve this requirement. The brush is usually directly fixed on the slider, and lacks a flexible folding or adjusting mechanism. Therefore, in unnecessary dustproof scenarios, the brush cannot be quickly disassembled or folded, which not only increases the difficulty of maintaining the equipment, but also reduces the adaptability of the equipment in complex environments.

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a dustproof structure for a closed linear motor module, which has the following beneficial effects:
[0018] 1. The adhesive strip on the pressure roller efficiently adsorbs dust and particles from the slide surface, keeping it clean. The pressure roller moves along the slider, covering the entire slide surface for thorough and even cleaning. A second motor drives the slider, eliminating the need for manual intervention and automating the cleaning process, thus improving efficiency.

[0030] Please see Figures 1-5 A dustproof structure for a closed linear motor module includes a slide table 1. A cleaning assembly is provided on the slide table 1. The cleaning assembly includes a second motor 2, a second threaded rod 3, a slider 4, a horizontal shaft 5, a pressure roller 6, and a stabilizing plate 7. The second motor 2 is fixedly installed on the slide table 1. The second threaded rod 3 is connected to the output end of the second motor 2. The slider 4 is threadedly connected to the second threaded rod 3 and slidably connected to the slide table 1. The horizontal shaft 5 is detachably installed on the slider 4. The pressure roller 6 is rotatably connected to the horizontal shaft 5. The stabilizing plate 7 is provided on the slider 4. A scraping assembly is provided on the slider 4. The scraping assembly includes a cleaning roller 8, a scraper 9, and a brush 10. The cleaning roller 8 is installed on the slider 4. The scraper 9 is located at one end of the cleaning roller 8, and the brush 10 is located on the inner side of the cleaning roller 8.
[0031] A locating pin 11 is detachably installed between the stabilizing plate 7 and the horizontal axis 5.
[0032] A spring 12 is sleeved on the positioning pin 11, and the two ends of the spring 12 are connected to the top of the positioning pin 11 and the horizontal shaft 5.
[0033] An adhesive tape 13 is fitted onto the outer side of the pressure roller 6.
[0034] The slide table 1 is provided with a fixing plate 14, and the slider 4 and the fixing plate 14 are provided with fixing holes 15.
[0035] In this embodiment, when dust needs to be scraped off the slide table 1 during use, the second motor 2 is started, causing the second threaded rod 3 at the output end to rotate. During its rotation, the slider 4 on it slides, and during the sliding movement of the slider 4, the pressure roller 6 mounted on the slider 4 rolls along the horizontal axis 5. During the rolling process, the adhesive tape 13 on the roller adsorbs the dust on the surface of the slide table 1, thereby keeping the surface clean. Furthermore, during the movement of the slider 4, the horizontal axis 5 slides up and down along the positioning pin 11. This compresses the spring 12, allowing it to effectively absorb dust from the slide table 1 under the influence of its elastic potential energy. During the sliding movement of the slider 4, the scraper 9 at one end of the cleaning roller 8 effectively scrapes away dust from the surface of the slide table 1. After scraping, the brush 10 on the cleaning roller 8 further removes the dust. Finally, during the sliding movement of the slider 4, once it reaches the desired position, it can be secured using external bolts in conjunction with the fixing plate 14 and the fixing holes 15 on the slider 4.
[0036] Please see Figure 2 As a dustproof structure implementation method for a closed linear motor module of the shielding component: a shielding component is provided on the outside of the slide table 1. The shielding component includes a top plate 16, a movable plate 17 and a dust cover 18. The top plate 16 is provided at one end of the slide table 1, the movable plate 17 is slidably connected to the slide table 1, and the dust cover 18 is provided between the movable plate 17 and the top plate 16.
[0037] A first motor 19 is installed at one end of the top plate 16, and a first threaded rod 20 is connected to the output end of the first motor 19.
[0038] The first threaded rod 20 is threadedly connected to the movable plate 17. A guide rod 21 is installed at one end of the top plate 16. The guide rod 21 is slidably connected to the movable plate 17. A cover plate 22 is installed on the slide table 1.
[0039] More specifically, during use, in order to prevent dust from entering the surface of the slide table 1, a dust cover 18 is used to shield its interior. When it needs to be retracted, the first motor 19 is started, which drives the first threaded rod 20 at the output end to rotate. During the rotation, the dust cover 18 on it slides along the guide rod 21, thereby completing the process of retracting the dust cover 18.
[0040] In summary, during use or operation of the overall equipment: When it is necessary to scrape dust off the slide table 1, the second motor 2 is started, causing the second threaded rod 3 at the output end to rotate. During this rotation, the slider 4 on it slides, causing the pressure roller 6 mounted on the slider 4 to roll along the horizontal axis 5. During this rolling, the adhesive tape 13 on the roller adsorbs the dust on the surface of the slide table 1, thus keeping the surface clean. Furthermore, during the movement of the slider 4, the horizontal axis 5 slides up and down along the positioning pin 11. During the sliding process, the spring 12 is compressed, and under the action of the elastic potential energy of the spring 12, the dust on the slide table 1 is fully adsorbed. During the sliding movement of the slider 4, the scraper 9 at one end of the cleaning roller 8 is used to scrape the surface of the slide table 1, thereby removing the dust from the surface of the slide table 1. After scraping, the dust is further scraped up by the brush 10 on the cleaning roller 8. During the sliding movement of the slider 4, after it moves to a suitable position, it can be fixed by the external bolts in conjunction with the fixing plate 14 and the fixing hole 15 on the slider 4.
[0041] During use, in order to prevent dust from entering the surface of the slide table 1, a dust cover 18 is used to shield its interior. When it is necessary to retract it, the first motor 19 is started, which drives the first threaded rod 20 at the output end to rotate. During the rotation, the dust cover 18 on it slides along the guide rod 21, thereby completing the process of retracting the dust cover 18.
