Detailed implementation manner
[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Here, it should be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.
[0024] In addition, it should also be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
[0025] The present utility model provides a linear motor module 100, including a base 200, a slide table 300 and a steel belt 400. The slide table 300 includes a base 310, and the base 310 is slidably connected to the base 200. The base 310 includes a first surface 311 facing away from the base 200. A first roller 320 and a second roller 330 parallel to the width direction of the base 200 are provided on the first surface 311. The distance from the first roller 320 to the base 200 is a first distance, and the distance from the second roller 330 to the base 200 is a second distance. The first distance is less than the second distance. The steel belt 400 is located on the side of the first roller 320 facing the base 200, and the steel belt 400 is located on the side of the second roller 330 facing away from the base 200.
[0026] This layout can effectively shield and protect the internal structure of the linear motor module 100, preventing external dust, impurities, etc. from entering, thereby maintaining the cleanliness and stable operation of the module. Since the distance between the first roller 320 and the base 200 is less than the distance between the second roller 330 and the base 200, a certain gap will be maintained between the steel belt 400 and the slide 300 when passing through. This design avoids hard contact between the steel belt 400 and the slide 300, reduces friction and wear, and helps to extend the service life of the steel belt 400 and the slide 300. The first roller 320 and the second roller 330 are parallel to the width direction of the base 200, providing a stable guiding effect for the steel belt 400. This helps to ensure that the slide 300 moves along the correct path, reduces deviation and jitter, and improves the operation accuracy and stability of the linear motor module 100.
[0027] Furthermore, the two first rollers 320 are symmetrically distributed along the midline in the length direction of the base 310, and the two second rollers 330 are symmetrically distributed along the midline in the length direction of the base 310. The first rollers 320 symmetrically distributed on both sides of the midline in the length direction of the base 310 and the second rollers 330 symmetrically distributed on both sides of the midline in the length direction of the base 310 can ensure that a good gap is always maintained between the steel belt 400 and the slide 300 when the steel belt 400 passes through the slide 300. In addition, this symmetrical distribution makes the force on the steel belt 400 on the slide 300 more uniform, avoiding the offset or wear of the steel belt 400 caused by uneven force, thereby improving the stability and accuracy of the operation of the linear motor module 100. The symmetrical design makes the installation and maintenance process of the linear motor module 100 simpler. Since all relevant components are symmetrically distributed, it is easier to ensure that all components are correctly aligned during installation, and it is also easier to check and replace components during maintenance.
[0028] Furthermore, the slide 300 includes card slots 312 located on both sides of the base 310. The base 200 is provided with guide rails extending in the length direction of the base 200, and the card slots 312 are configured to be slidably connected to the guide rails. The close fit between the card slots 312 and the guide rails ensures that the slide 300 can slide smoothly and stably relative to the base 200. This design reduces friction and resistance during the sliding process of the slide 300, improving the operation efficiency and accuracy of the linear motor module 100. The guide rails provide a stable guiding path for the slide 300, ensuring the linearity and stability of the slide 300 during movement, which helps to reduce deviation and jitter and improve the overall performance of the linear motor module 100. In addition, the design of the card slots 312 and the guide rails makes the installation and disassembly of the slide 300 simple and fast, and also facilitates the daily maintenance and servicing of the guide rails and the slide 300.
[0029] Further, the card slot 312 includes an upper rod portion 3121 away from the base 200. The first roller 320 and the second roller 330 are mounted on the upper rod portion 3121 on both sides of the base 310. An installation position 3122 is provided on the side of the upper rod portion 3121 facing the base 310. An elastic member 3123 is provided in the installation position 3122. At least a part of the first roller 320 extends into the installation position 3122 and is connected to the elastic member 3123. Brush hairs are arranged on the first roller 320 and the second roller 330. The first roller 320 is connected to the upper rod portion 3121 through the elastic member 3123. This design plays a buffering role during the sliding process of the slide 300. When the slide 300 is impacted or vibrated, the elastic member 3123 can absorb part of the energy, reducing damage to the slide 300, the base 200, and the steel belt 400. The existence of the elastic member 3123 also allows a certain degree of automatic adjustment of the first roller 320 during installation and use. This helps to keep the gap between the steel belt 400 and the first roller 320 constant, improving the running stability and accuracy of the module.
[0030] Further, the slide 300 further includes a cover plate 350. The cover plate 350 is snap-connected to the upper rod portion 3121, and the cover plate 350 covers the base 310, the first roller 320, and the second roller 330. The cover plate 350 can effectively prevent external impurities such as dust and moisture from entering the inside of the slide 300, protecting the base 310, the first roller 320, the second roller 330, and other precision components from pollution and damage. This is crucial for maintaining the cleanliness of the slide 300 and extending the service life of the linear motor module 100.
[0031] In some embodiments, the linear motor module 100 includes at least two slides 300. Multiple slides 300 can perform different tasks simultaneously or in parallel, thus significantly improving the overall processing capacity and efficiency of the production line. This parallel processing ability helps to shorten the production cycle and increase the output. In the case where a single slide 300 cannot meet the high-efficiency production requirements, increasing the number of slides 300 can reduce the waiting time and make the production process smoother. Multiple slides 300 can share the load, reducing the bearing pressure on a single slide 300, thereby improving the stability and accuracy of the overall system. Each slide 300 can be independently controlled to achieve finer motion control and positioning accuracy. This independent control ability helps to reduce error accumulation and improve the production quality.
[0032] Further, a third roller 340 is also provided on the first surface 311. The third roller 340 is located between the first roller 320 and the second roller 330, and the steel belt 400 is located on the side of the third roller 340 facing away from the base. In the case of long-distance transmission or high-speed movement, the steel belt 400 is prone to sagging or bending. The setting of the third roller 340 can effectively prevent or alleviate this phenomenon, maintaining the flatness and stability of the steel belt 400.
[0033] In this embodiment, the first roller 320, the second roller 330, and the third roller 340 are all connected to the upper rod portion 3121 through bearings at both ends. The bearings use nano - coatings. The bearings with nano - coatings have very high physical hardness, which enables them to effectively resist wear and extend the service life of the bearings. In addition, the bearings with nano - coatings can achieve self - lubrication, eliminating the need for oil injection, making the use process more convenient and labor - saving. At the same time, they also have good adhesion, making the connection stability between each roller and the upper rod portion 3121 better.
[0034] The first surface 311 protrudes away from the base 200. The protruding first surface 311 may include reserved mounting holes or interfaces. These designs help simplify the installation process of the device, reduce the installation difficulty and cost. It can also improve the air circulation inside the slider, making it easier for heat to dissipate and preventing the linear motor module 100 from overheating.
[0035] In summary, for the linear motor module 100 of the present utility model, the steel belt 400 is placed on the side of the first roller 320 facing the base 200 and the side of the second roller 330 facing away from the base 200. This layout can effectively shield and protect the internal structure of the linear motor module 100, preventing external dust, impurities, etc. from entering, thereby maintaining the cleanliness and stable operation of the module. Since the distance between the first roller 320 and the base 200 is less than the distance between the second roller 330 and the base 200, there will be a certain gap between the steel belt 400 and the slider 300 when passing through. This design avoids hard contact between the steel belt 400 and the slider 300, reduces friction and wear, and helps extend the service life of the steel belt 400 and the slider 300.
[0036] The above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model.
