Description
Technical Field
[0001] This utility model relates to the field of linear motors, and in particular to a Class 100 cleanroom fully enclosed linear motor module. Background Technology
[0002] Linear motor modules, also known as linear modules or linear motors, are system integrations based on linear motors, linear scales, Hall effect sensors, linear guides, etc. With industry development, linear motor modules have gradually replaced traditional lead screw and belt modules. Linear motor modules offer a range of advantages, including high individual movement speed, high repeatability, and long service life, significantly improving production efficiency.
[0003] The existing Class 100 cleanroom fully enclosed linear motor module moves to both ends of the guide rail during the reciprocating movement of the slide. The two ends of the guide rail lack a buffer and limiting structure, which causes impact collisions between the slide and the two ends of the guide rail, resulting in vibration of the fully enclosed linear motor module. This leads to gaps at the connection of the fully enclosed linear motor module, allowing external dust to enter the interior of the fully enclosed linear motor module. Moreover, after prolonged use, dust accumulates inside the fully enclosed linear motor module, and it is not possible to remove the dust from the inside of the base without disassembling the fully enclosed linear motor module. Utility Model Content
[0004] The purpose of this utility model is to provide a Class 100 cleanroom fully enclosed linear motor module, which solves the problem that the slide table will move to both ends of the guide rail. The lack of buffer and limiting structure at both ends of the guide rail will cause impact collisions between the slide table and the two ends of the guide rail, resulting in vibration of the fully enclosed linear motor module. This will lead to gaps at the connection of the fully enclosed linear motor module, allowing external dust to enter the interior of the fully enclosed linear motor module.
[0005] To achieve this objective, the present invention adopts the following technical solution: A Class 100 cleanroom fully enclosed linear motor module includes a base, a fully enclosed slide body mounted on the top of the base, a soft belt connected to the bottom of the fully enclosed slide body, a guide rail mechanism between the top of the base and the bottom of the fully enclosed slide body on both sides, a limit buffer mechanism at both ends of the guide rail mechanism, a groove inside the base, a dust extraction mechanism inside the groove, and a scraping mechanism installed inside the groove. The guide rail mechanism includes a guide rail with a U-shaped cross-section and a soft pad bonded to its inner surface. The bottom ends of the two ends of the fully enclosed slide body are slidably mounted on the top of the guide rail.
[0006] Furthermore, the base is horizontally positioned, the guide rail is a long strip structure, the soft pad has a U-shaped cross-section and is made of elastic rubber material, and the soft strip is sealed and connected to the top of the base.
[0007] Furthermore, the limiting and buffering mechanism includes a buffer pad and a buffer spring. A buffer rod is connected to the middle of the outer side of the buffer pad, and the buffer spring is sleeved on the surface of the buffer rod. The buffer pad and the buffer spring are elastically installed at both ends inside the guide rail.
[0008] Furthermore, the buffer pad adopts an elastic rubber pad structure, the buffer rod is horizontally arranged, and baffles are installed at both ends of the guide rail. The baffles are rectangular in structure and are vertically arranged.
[0009] Furthermore, a guide hole is provided in the middle of the surface of the baffle, the buffer rod slides through the guide hole, and the buffer spring is connected between the buffer pad and the baffle and is naturally extended.
[0010] Furthermore, the buffer rod is a threaded rod structure with a nut connected to its surface, and the nut is located on the outside of the baffle.
[0011] Furthermore, bolts are connected to the four outer corners of the baffle, and the inner end of the bolt is threaded into the outer end of the guide rail.
[0012] Furthermore, the dust extraction mechanism includes an exhaust pipe inserted into the middle of the groove, with exhaust holes evenly distributed on its surface and horizontally positioned, and one outer end is a closed structure. The other outer end of the exhaust pipe passes through one end of the base and is equipped with an exhaust fan, which is fixedly installed on the outer end of the base.
[0013] Furthermore, the scraping mechanism includes a scraping plate that scrapes against the inner surface of the groove. The scraping plate has a rotating hole in the middle, which is a threaded hole structure, and insertion holes on both sides. A through hole is formed on the surface of the scraping plate at the bottom of the rotating hole, and scraping sleeves are bonded to both sides of the through hole.
[0014] Furthermore, the internal thread of the rotating hole rotates through a rotating rod, one end of which is equipped with a motor, which is mounted on the other end of the base. The insertion hole slides through a guide rod, which is horizontally positioned. The exhaust pipe slides through the through hole, and the scraping sleeve slides onto the surface of the exhaust pipe.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. A soft pad is installed inside the guide rail, and a limiting and buffering structure is set at both ends. Therefore, when the fully enclosed slide body moves on the guide rail, the soft pad reduces friction and vibration. When it moves to both ends of the guide rail, it squeezes the buffer pad and buffer spring and is elastically buffered and limited, avoiding impact and collision between the fully enclosed slide body and the two ends of the guide rail, reducing vibration, preventing gaps from appearing in the fully enclosed linear motor module due to vibration, reducing dust entering the interior of the fully enclosed linear motor module, and the baffle can be removed and installed, and the buffer pad and buffer spring can be disassembled, replaced and maintained.
[0016] 2. An exhaust duct is installed inside the base, and exhaust holes are evenly distributed on the surface of the exhaust duct. Therefore, during long-term use of the fully enclosed linear motor module, there is no need to disassemble the fully enclosed linear motor module. The exhaust fan draws air from inside the exhaust duct, creating a negative pressure inside the exhaust duct. This allows dust and air inside the base to enter the exhaust duct through the exhaust holes, and then be drawn out and discharged to the outside by the exhaust fan. Therefore, dust can be continuously extracted from the inside of the fully enclosed linear motor module, reducing dust accumulation.
[0017] 3. The scraper is slidably installed inside the groove. Therefore, during long-term use of the fully enclosed linear motor module, the motor drives the rotating rod to rotate in both directions, thereby driving the scraper to move back and forth along the guide rod inside the groove. This scrapes the dust adhering to the inner surface of the groove and the surface of the exhaust pipe, improving the degree of dust suction from the exhaust pipe to the inside of the groove.

Class 100 cleanroom fully enclosed linear motor modules can shine in clean environments. Their key components utilize wear-resistant materials and advanced surface treatment technology, ensuring stable performance during long-term operation.
[0026] Example 1 See Figures 1 to 5 This utility model embodiment provides a Class 100 cleanroom fully enclosed linear motor module, including a base 1, a fully enclosed slide body 7 mounted on the top of the base 1, a soft belt 3 connected to the bottom of the fully enclosed slide body 7, a guide rail mechanism between the top of the base 1 and the bottom of the fully enclosed slide body 7 on both sides, a limit buffer mechanism at both ends of the guide rail mechanism, a groove 10 inside the base 1, a dust extraction mechanism inside the groove 10, and a scraping mechanism installed inside the groove 10.
[0027] The guide rail mechanism includes a guide rail 4, which has a U-shaped cross-section and a soft pad 5 bonded to its inner surface. The bottom ends of the fully enclosed slide body 7 are slidably mounted on the top of the guide rail 4.
[0028] When the fully enclosed slide body 7 moves on the guide rail 4, friction and vibration are reduced by the soft pad 5.
[0029] The base 1 is horizontally positioned, the guide rail 4 is a long strip structure, the soft pad 5 has a U-shaped cross-section and is made of elastic rubber, and the soft strip 3 is sealed and connected to the top of the base 1.
[0030] The limiting and buffering mechanism includes a buffer pad 15 and a buffer spring 14. A buffer rod 12 is fixedly connected to the middle of the outer side of the buffer pad 15. The buffer spring 14 is sleeved on the surface of the buffer rod 12. The buffer pad 15 and the buffer spring 14 are elastically installed at both ends inside the guide rail 4.
[0031] The buffer pad 15 adopts an elastic rubber pad structure, and the buffer rod 12 is set horizontally.
[0032] The guide rail 4 has baffles 6 installed at both ends. The baffles 6 are rectangular and vertically arranged.
[0033] A guide hole 16 is opened in the middle of the surface of the baffle 6, and the buffer rod 12 slides through the guide hole 16.
[0034] The buffer spring 14 is connected between the buffer pad 15 and the baffle 6, and is set to extend naturally.
[0035] When the fully enclosed slide body 7 moves to both ends of the guide rail 4, it squeezes the buffer pad 15 and the buffer spring 14 and is elastically buffered and limited, so as to avoid impact and collision between the fully enclosed slide body 7 and the two ends of the guide rail 4, reduce the impact between the two ends of the slide body 7 and the guide rail 4, reduce the impact vibration of the slide body 7 and the guide rail 4, prevent the fully enclosed linear motor module from being vibrated and gaps from appearing, and reduce the entry of dust into the interior of the fully enclosed linear motor module.
[0036] The buffer rod 12 is a threaded rod structure, and a nut 13 is connected to its surface. The nut 13 is located on the outside of the baffle 6.
[0037] Bolts 11 are connected to the four outer corners of the baffle 6, and the inner thread of the bolt 11 is inserted into the outer end of the guide rail 4.
[0038] The baffle 6 can be detached and installed, and the buffer pad 15 and buffer spring 14 can be disassembled, replaced and maintained.
[0039] Example 2 See Figures 1 to 5 This utility model embodiment provides a Class 100 cleanroom fully enclosed linear motor module, including a base 1, a fully enclosed slide body 7 mounted on the top of the base 1, a soft belt 3 connected to the bottom of the fully enclosed slide body 7, a guide rail mechanism between the top of the base 1 and the bottom of the fully enclosed slide body 7 on both sides, a limit buffer mechanism at both ends of the guide rail mechanism, a groove 10 inside the base 1, a dust extraction mechanism inside the groove 10, and a scraping mechanism installed inside the groove 10.
[0040] The dust extraction mechanism includes an exhaust pipe 8, which is inserted into the middle of the groove 10. Its surface is evenly provided with exhaust holes 9 and is set horizontally. One outer end is a closed structure. The other outer end of the exhaust pipe 8 passes through one end of the base 1 and is equipped with a blower 2. The blower 2 is fixedly installed on the outer end of the base 1.
[0041] During long-term use of the fully enclosed linear motor module, there is no need to disassemble the fully enclosed linear motor module. The exhaust fan 2 draws air from inside the exhaust pipe 8, creating a negative pressure inside the exhaust pipe 8. This causes dust and air inside the base 1 to enter the exhaust pipe 8 through the exhaust hole 9, and then be drawn out and discharged to the outside by the exhaust fan 2. Therefore, dust can be continuously extracted from the inside of the fully enclosed linear motor module, reducing dust accumulation.
[0042] Example 3 See Figures 1 to 5This utility model embodiment provides a Class 100 cleanroom fully enclosed linear motor module, including a base 1, a fully enclosed slide body 7 mounted on the top of the base 1, a soft belt 3 connected to the bottom of the fully enclosed slide body 7, a guide rail mechanism between the top of the base 1 and the bottom of the fully enclosed slide body 7 on both sides, a limit buffer mechanism at both ends of the guide rail mechanism, a groove 10 inside the base 1, a dust extraction mechanism inside the groove 10, and a scraping mechanism installed inside the groove 10.
[0043] The scraping mechanism includes a scraping plate 17, which scrapes against the inner surface of the groove 10. A rotating hole 21 is opened in the middle of the scraping plate 17. The rotating hole 21 is a threaded hole structure, and insertion holes 22 are opened on both sides of it. A through hole 23 is opened on the surface of the scraping plate 17 at the bottom of the rotating hole 21. Scraping sleeves 24 are bonded to both sides of the through hole 23.
[0044] The internal thread of the rotating hole 21 rotates through the rotating rod 19. A motor 20 is installed at one end of the rotating rod 19, and the motor 20 is installed at the other end of the base 1. The sliding hole 22 is slidably passed through the guide rod 18, which is horizontally set. The exhaust pipe 8 slides through the through hole 23, and the scraping sleeve 24 is slidably sleeved on the surface of the exhaust pipe 8.
[0045] Working method: The fully enclosed slide body 7 moves back and forth along the guide rail 4. The fully enclosed slide body 7 presses against the top of the soft belt 3 and slides relative to the soft belt 3, so that the linear motor module runs smoothly. Moreover, external dust will not enter the base 1 through the gap.
[0046] A soft pad 5 is installed inside the guide rail 4, and a limiting buffer structure is set at both ends of the guide rail 4. Therefore, when the fully enclosed slide body 7 moves on the guide rail 4, the soft pad 5 reduces friction and vibration. When the fully enclosed slide body 7 moves to both ends of the guide rail 4, it squeezes the buffer pad 15 and the buffer spring 14 and is elastically buffered and limited, avoiding impact and collision between the fully enclosed slide body 7 and the two ends of the guide rail 4, reducing vibration, preventing the fully enclosed linear motor module from being vibrated and gaps from appearing, reducing dust entering the interior of the fully enclosed linear motor module. In addition, the baffle 6 can be detached and installed, and the buffer pad 15 and the buffer spring 14 can be disassembled, replaced and maintained.
[0047] An exhaust pipe 8 is installed inside the base 1, and exhaust holes 9 are evenly distributed on the surface of the exhaust pipe 8. Therefore, during long-term use of the fully enclosed linear motor module, there is no need to disassemble the fully enclosed linear motor module. The exhaust fan 2 draws air from inside the exhaust pipe 8, creating a negative pressure inside the exhaust pipe 8. This allows dust and air inside the base 1 to enter the exhaust pipe 8 through the exhaust holes 9, and then be drawn out and discharged to the outside by the exhaust fan 2. Thus, dust can be continuously extracted from the inside of the fully enclosed linear motor module, reducing dust accumulation.
[0048] A scraper 17 is slidably installed inside the groove 10. Therefore, during long-term use of the fully enclosed linear motor module, the motor 20 drives the rotating rod 19 to rotate in both directions, thereby driving the scraper 17 to move back and forth along the guide rod 18 inside the groove 10. This scrapes the dust adhering to the inner surface of the groove 10 and the surface of the exhaust pipe 8, improving the suction degree of the exhaust pipe 8 on the dust accumulated inside the groove 10 and preventing dust from adhering and depositing on the inner surface of the groove 10 and becoming difficult to clean and extract.
[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
