Description

Linear module to reduce dust generation

The present invention relates to a linear module, and more particularly to a linear module that can reduce dust generation and facilitate the installation of magnetic components.

Existing linear modules for reducing dust generation, such as those disclosed in Republic of China Patent No. I681134, use magnets to magnetically attract the dust-proof tape to reduce dust generation. This technique involves directly drilling holes in the magnets and locking them to the slide. However, due to limitations in the magnet's magnetic properties and the materials that can be used, this technique can only be used with weaker magnets. Furthermore, applying excessive force when locking the magnets can damage them.

Referring to Figures 1 to 8 , the present invention provides a linear module capable of reducing dust generation according to one embodiment, comprising a track unit 10, a slide 20, an outer cover 30, a dustproof belt 40, two magnetic assemblies 50, and a plurality of rollers 60.

The track unit 10 is configured to extend in a displacement axis X. For example, the track unit 10 includes a track base 11, two side covers 12, two end covers 13, and two magnetic strips 14. The track base 11 is a U-shaped base extending along the displacement axis X, including a bottom 111 and two side walls 112 respectively connected to opposite sides of the bottom 111. The top of each side wall 112 is provided with a slot 113 for the insertion of the side cover 12, so that the track base 11 and the side covers 12 can jointly form a sliding channel CH. The inner surface of each side wall 112 is provided with a track rolling groove 114. Each side cover 12 has a long slot 121 at its top for the corresponding magnetic strip 14. The two end covers 13 are fixed to the opposite end surfaces of the track base 11 along the displacement axis X, laterally covering the sliding channel CH. Each side cover 12 is fixed to the two end covers 13.

The slide 20 is slidably disposed in the sliding channel CH of the track unit 10 along the displacement axis X. For example, the slide 20 includes a sliding base 21 and a fixed platform 22 mounted on the sliding base 21. Two opposing side surfaces 211 of the sliding base 21 are each recessed with a slide rolling groove 212. The two slide rolling grooves 212 correspond to two track rolling grooves 114, respectively. Each slide rolling groove 212 and the corresponding track rolling groove 114 together form a recirculation channel for the rolling balls 60.

The outer cover 30 is mounted on the fixed platform 22 of the slide 20. The dustproof belt 40 is a metal belt that can be configured to pass between the slide 20 and the outer cover 30. The opposite ends of the dustproof belt 40 in the displacement axis X are fixed to opposite sides of the track unit 10 in the displacement axis X, for example, to the end covers 13. The opposite ends of the dustproof belt 40 in an axis Q perpendicular to the displacement axis X are attracted by magnetic strips 14. This seals the dustproof belt 40 between the side covers 12, suppresses displacement of the dustproof belt 40, and vertically covers the slide channel CH.

Two magnetic assemblies 50 are disposed on opposite sides of the slide 20 along the displacement axis X. Each magnetic assembly 50 includes a fixing frame 51 and two magnetic elements 52.

The fixing frame 51 can accommodate the magnetic element 52 and is arranged on one side of the slide 20, for example but not limited to being fixed on an end surface of the sliding base 21 facing the end cover 13 in the displacement axis X (i.e., the mounting surface 213). For example, the fixing frame 51 in this embodiment includes two mounting parts 511, a supporting part 512, a first limiting part 513 and a second limiting part 514. The mounting part 511 can be fixed to the mounting surface 213 of the sliding base 21. The supporting part 512 is connected to the mounting part 511 and can support the magnetic element 52. The first limiting part 513 is connected to the supporting part 512 and can limit the magnetic element 52 in a first axial direction D1. The second limiting part 514 is connected to the supporting part 512 and can limit the magnetic element 52 in a second axial direction D2. The first axis D1 is not parallel to the second axis D2; for example, the first axis D1 is perpendicular to the second axis D2.

At least a portion of the second limiting portion 514 is inclined relative to the supporting portion 512. For example, the angle between at least a portion of the second limiting portion 514 and the supporting portion 512 is greater than 0 degrees but less than 90 degrees. In this embodiment, the second limiting portion 514 is, for example but not limited to, bent at a angle greater than 0 degrees but less than 90 degrees, and includes a first section 5141 connected to the supporting portion 512 and a second section 5142 connected to the first section 5141. The angle θ1 between the first section 5141 and the second section 5142 is greater than 0 degrees but less than 90 degrees, and the angle θ2 between the second section 5142 and the supporting portion 512 is greater than 0 degrees but less than 90 degrees. The first section 5141 of the second retaining portion 514 connects to the first retaining portion 513, forming a flat plate. Therefore, the angle between the first retaining portion 513 and the second section 5142 of the second retaining portion 514 is also greater than 0 degrees but less than 90 degrees. In other embodiments, the second retaining portion may be completely separated from the first retaining portion. Alternatively, if the second retaining portion is completely separated from the first retaining portion, the second section may be omitted, and the first section may be inclined to form an angle greater than 0 degrees but less than 90 degrees with the supporting portion.

In this embodiment, the mounting bracket 51 may further include a second limiting portion 514 connected to the supporting portion 512 and capable of limiting the magnetic element 52 in the second axial direction D2. The two second limiting portions 514 are located on opposite sides of the first limiting portion 513. In other embodiments, the mounting bracket may be provided with only one second limiting portion.

In this embodiment, the fixing frame 51 may further include a third limiting portion 515 connected to the first limiting portion 513 and capable of limiting the magnetic element 52 along a third axis D3. The angle between the third limiting portion 515 and the first limiting portion 513 is greater than 0 degrees but less than 180 degrees, for example, substantially approximately 90 degrees. The first axis D1, the second axis D2, and the third axis D3 are non-parallel to each other, for example, perpendicular to each other. In other embodiments, the third limiting portion may be omitted.

In this embodiment, the first limiting portion 513 and the third limiting portion 515 are both integral components. In other embodiments, at least one of the first limiting portion and the third limiting portion may be composed of multiple components.

In this embodiment, the mounting bracket 51 may further include a fourth limiting portion 516 connected to the supporting portion 512 and capable of limiting the magnetic element 52 in the first axial direction D1. The first limiting portion 513 and the fourth limiting portion 516 are located on opposite sides of the supporting portion 512. In other embodiments, the mounting bracket may omit the fourth limiting portion, or the fourth limiting portion may be integrated with other components (such as the mounting portion) into a single component.

In this embodiment, the second stopper 514 and the third stopper 515 are both located on the side of the support portion 512 that is closer to the mounting surface 213. In other embodiments, at least one of the second stopper and the third stopper may be located on a side of the support portion that is farther from the mounting surface.

In this embodiment, the mounting bracket 51 is made of a non-magnetic material to avoid affecting the magnetic conductivity of the magnetic element 52 and preventing it from affecting the operation of components near the linear module during the operation of the slide 20. For example, this could prevent sensors near the linear module from being affected by magnetic forces and reducing measurement accuracy.

In this embodiment, the mounting bracket 51 may be made of a metal with low elasticity (such as, but not limited to, sheet metal or aluminum). In other embodiments, it may be made of other materials, such as, but not limited to, elastic metal (such as, but not limited to, spring steel or stainless steel) or polymer materials (such as, but not limited to, plastic).

The magnetic element 52, such as a magnet, can magnetically attract the dust-proof belt 40. After installation and positioning, the top surface 521 of the magnetic element 52 is lower than the top surface of the side cover 12. A gap exists between the dust-proof belt 40 and the top surface 521 of the magnetic element 52. A gap also exists between the dust-proof belt 40 and the bottom surface 31 of the outer cover 30. Consequently, when the magnetic element 52 moves relative to the dust-proof belt 40, the magnetic element 52 magnetically attracts the dust-proof belt 40, maintaining a distance between the dust-proof belt 40 and the fixed platform 22 and the outer cover 30. A gap is also maintained between the dust-proof belt 40 and the magnetic element 52. Therefore, the dust-proof belt 40 does not rub against the slide 20, the outer cover 30, or the magnetic element 52, generating dust or fine particles. This allows the linear module to operate normally while maintaining a standard operating environment. In this embodiment, the number of magnetic elements 52 can be changed to one or more than two depending on the system's magnetic force requirements and the strength of the magnetic elements 52 themselves.

In this embodiment, the magnetic element 52 (its surface closest to the slide mounting surface) is positioned, for example but not limited to, approximately 116% to 160% of the length of the fixed platform 22 in the displacement axis X. This helps ensure that the section of the dustproof belt 40 within the projection of the outer cover 30 effectively covers the sliding channel CH, preventing workplace dust from entering the track unit 10 and affecting the operation of the linear module.

The following exemplifies the process of installing the magnetic element 52 on the fixing frame 51. Before the magnetic element 52 is installed on the fixing frame 51, the initial state of the second limiting portion 514 is configured to be bent at an angle greater than 90 degrees but less than 180 degrees, or configured to be a flat plate perpendicular to the supporting portion 512. In this case, the second section 5142 of the second limiting portion 514 is located in a passable position, so that the magnetic element 52 can freely enter and exit the range of the supporting portion 512 in the second axial direction D2. After the magnetic element 52 is installed on the fixing frame 51, the second limiting portion 514 can be bent inward toward the supporting portion 512, so that the second section 5142 of the second limiting portion 514 approaches the supporting portion 512 until it reaches a predetermined stop position, thereby limiting or inhibiting the movement of the magnetic element 52 in the second axial direction D2. Once the second section 5142 of the second stopper 514 reaches the stop position, it will not automatically return to the passable position. This allows the magnetic element 52 to remain positioned at the desired location without the need for drilling or locking.

Referring to Figures 9 to 11 , another embodiment of a magnetic assembly 70 for a linear module capable of reducing dust generation is shown. Its mounting bracket 71 can be made of a low-elasticity metal, elastic metal, or polymer material and includes an integral mounting portion 711, a supporting portion 712, two first retaining portions 713, two second retaining portions 714, and two third retaining portions 715.

The mounting portion 711 is located on the side of the supporting portion 712 closest to the mounting surface 221 of the fixed platform 22 and can be secured to the mounting surface 221. The first stopper 713, the second stopper 714, and the third stopper 715 are all located on the side of the supporting portion 712 away from the mounting surface 221. The two first stoppers 713, the two second stoppers 714, and the two third stoppers 715 are disposed on opposite sides of the supporting portion 712 along the axis Q perpendicular to the displacement axis X.

In this embodiment, the first sections 7141 of the two second stoppers 714 are respectively connected to the adjacent first stoppers 713. The angle between the first section 7141 and the second section 7142 of each second stopper 714 is greater than 0 degrees but less than 90 degrees, while the angle between the second section 7142 and the supporting portion 712 is greater than 0 degrees but less than 90 degrees. The first section 7141 is connected to the first stopper 713 to form a flat plate, so the angle between the first stopper 713 and the second section 7142 is also greater than 0 degrees but less than 90 degrees. However, the present invention is not limited to this. In other embodiments, the second retaining portion may be completely separated from the first retaining portion. Alternatively, if the second retaining portion is completely separated from the first retaining portion, the second section may be omitted, and the first section may be inclined and have an angle with the support portion greater than 0 degrees but less than 90 degrees.

For example, if the fixing frame 71 is made of a metal with low elasticity, before the magnetic element 52 is mounted on the fixing frame 71, the initial state of the second limiting portion 714 is configured to be bent at a angle greater than 90 degrees but less than 180 degrees, or configured to be flat. In this state, the second section 7142 of the second limiting portion 714 is located in a passable position, so that the magnetic element 52 can freely enter and exit the range of the supporting portion 712 in the second axial direction D2. After the magnetic element 52 is mounted on the fixing frame 71, the second limiting portion 714 can be bent inward toward the supporting portion 712, so that the second section 7142 of the second limiting portion 714 approaches the supporting portion 712 until it reaches a predetermined stop position, thereby limiting or inhibiting the movement of the magnetic element 52 in the second axial direction D2. Once the second section 7142 of the second stopper 714 reaches the stop position, it will not automatically return to the pass position. This allows the magnetic element 52 to remain positioned at the predetermined position.

Referring to Figures 12 to 14 , another embodiment of a magnetic assembly 80 for a linear module capable of reducing dust emissions is shown. Its mounting frame 81 includes two mounting portions 811, a supporting portion 812, an integral first retaining portion 813, two second retaining portions 814, an integral third retaining portion 815, and a fourth retaining portion 816. The configuration of the mounting portions 811, first retaining portion 813, third retaining portion 815, and fourth retaining portion 816 can be referenced to the configuration of the mounting portion 511, first retaining portion 513, third retaining portion 515, and fourth retaining portion 516 of the mounting frame 51 and will not be further described here.

The supporting portion 812 is provided with a first engaging structure 8121, and the second section 8142 of the second limiting portion 814 is provided with a second engaging structure 8143 that can engage with the first engaging structure 8121.

In the present embodiment, the fixing frame 81 can be made of a polymer material (such as but not limited to plastic). The following exemplifies the process of installing the magnetic element 52 on the fixing frame 81. Before the magnetic element 52 is installed on the fixing frame 81, the initial state of the second limiting portion 814 is configured to be bent at an angle greater than 0 degrees but less than 90 degrees. In this case, the second section 8142 of the second limiting portion 814 is located at a stop position, and the second engaging structure 8143 of the second limiting portion 814 is engaged with the first engaging structure 8121 of the supporting portion 812, so that the magnetic element 52 cannot enter the range of the supporting portion 812. When the magnetic element 52 is to be installed on the fixing frame 81, the second limiting portion 814 can be pushed outward to disengage the second locking structure 8143 from the first locking structure 8121, and the second section 8142 of the second limiting portion 814 is moved away from the supporting portion 812 until a pass position is reached. In this case, the second limiting portion 814 is bent at a angle greater than 90 degrees but less than 180 degrees, or is in the shape of a flat plate, so that the magnetic element 52 can freely enter and exit the range of the supporting portion 812 on the second axial direction D2. After the magnetic element 52 is mounted on the mounting bracket 81, the second stopper 814 can be further moved to engage the second engaging structure 8143 with the first engaging structure 8121. This positions the second section 8142 of the second stopper 814 in the stop position, thereby limiting or inhibiting movement of the magnetic element 52 in the second axial direction D2.

Referring to Figures 15A to 15C , another embodiment of a magnetic attraction assembly 90 for a linear module capable of reducing dust generation is shown. The mounting frame 91 includes a mounting portion 911, a supporting portion 912, a first retaining portion, a second retaining portion 914, a third retaining portion 915, and a fourth retaining portion 916. The configuration of the mounting portion 911, supporting portion 912, first retaining portion, second retaining portion 914, third retaining portion 915, and fourth retaining portion 916 can be referenced to the configuration of the mounting portion 511, supporting portion 512, first retaining portion 513, second retaining portion 514, third retaining portion 515, and fourth retaining portion 516 of the mounting frame 51, and will not be further described herein.

In this embodiment, the mounting bracket 91 can be made of elastic metal. The following exemplifies the process of mounting the magnetic element 52 on the mounting bracket 91. Before the magnetic element 52 is mounted on the mounting bracket 91, the second stopper 914 is initially configured to be bent at an angle greater than 0 degrees but less than 90 degrees. In this position, the second section 9142 of the second stopper 914 is located at a predetermined stop position, preventing the magnetic element 52 from entering the support portion 912. To install the magnetic element 52 on the mounting bracket 91, the second stopper 914 is pulled outward, moving the second section 9142 of the second stopper 914 away from the support portion 912 until it reaches a passable position. In this position, the second stopper 914 is bent at an angle greater than or equal to 90 degrees but less than 180 degrees, allowing the magnetic element 52 to freely enter and exit the support portion 912 along the second axis. After the magnetic element 52 is installed on the mounting bracket 91, the force applied to the second stopper 914 can be removed, causing the second section 9142 to automatically return to the stop position, thereby limiting or inhibiting movement of the magnetic element 52 along the second axis.

In summary, the magnetic assembly provided by the present invention, through the design of the mounting bracket, is compatible with linear modules of various sizes. In particular, the design of the mounting bracket's second stop facilitates installation of the magnetic element, unconstrained by limited mounting space. Furthermore, since drilling holes for the magnetic element is unnecessary, smaller magnetic elements with greater magnetic properties can be used. This not only enhances the effectiveness of the magnetic dust strip but also reduces the size of the magnetic assembly to accommodate smaller linear modules. The relative positioning of the magnetic element and the mounting platform along the displacement axis ensures that the dust strip within the projection of the outer cover effectively covers the sliding channel, preventing workplace dust from entering the track unit and impacting the operation of the linear module. In addition, using a mounting bracket made of non-magnetic material can avoid affecting the magnetic conductivity of the magnetic components and the operation of components near the linear module.
