Description

Technical Field

[0001] The utility model relates to the technical field of linear motors, in particular to a linear motor module. Background Art

[0002] A linear motor module usually includes a base, a slide slidably connected to the base, and a mover assembly and a stator assembly that drive the slide to slide. In order to prevent foreign matter from entering the interior of the linear motor module, a protective cover is usually added above the slide. While playing a protective role, it also ensures the beauty of the linear motor module.

[0003] In existing semi-enclosed linear motor modules, there is a gap of a certain width between the protective cover and the slide to avoid the shuttle of the slide. Small parts or other foreign objects can enter the interior of the linear motor module through the gap on the side, which may cause jamming and motor damage. The protection effect is general and is not suitable for scenarios with a lot of particles.

[0004] In a fully enclosed linear motor module, a steel belt is used to pass through the slide along the extension direction of the base. Except for the part that passes through the slide, the rest of the steel belt is tightly attached to the inner side of the base, achieving a full seal on the top of the base. The fully sealed structure of the linear motor module is also not conducive to heat dissipation, resulting in reduced performance of the linear motor module. In addition, the interior of the slide is a curved surface with a friction plate made of wear-resistant material attached to the curved surface. The friction plate is used to support the steel belt as the slide slides along the base and generates friction between the steel belt and the steel belt. The steel belt will deform after long-term use and requires frequent maintenance and replacement. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

The two end plates 4 are respectively connected to the base 1 in the longitudinal direction (such as Figure 3 The two ends of the cover plate 3 are fixed to the two end plates 4 respectively. (It should be noted that, unless otherwise specified, the "end", "end surface" or "two ends" described in this embodiment refer to the end sides along the longitudinal direction; the top and bottom refer to the vertical direction (such as Figure 3 Top and bottom in the z-direction)

[0036] In this embodiment, the end plates 4 block both ends of the base 1 in the longitudinal direction, which can protect the components inside the base 1; at the same time, an installation site for the cover plate 3 is provided, and the cover plate 3 is mounted above the base 1 through the end plates 4 to avoid friction with the slide 2.

[0037] Further, if Figure 2 、 Figure 3 As shown, the base 1 has two guide rails 11 and a bottom wall 12. The two guide rails 11 are in the transverse direction (such as Figure 2The two guide rails 11 are separated from each other in the x-direction (the x-direction is roughly perpendicular to the z-direction and the y-direction) and extend along the longitudinal direction perpendicular to the transverse direction, and first bead grooves 111 opposite to each other are respectively opened on the two guide rails 11; the bottom wall 12 is fixed and connected to the two guide rails 11 in the transverse direction, and the surface of the two guide rails 11 facing away from the bottom wall 12 is the guide rail top surface 112.

[0038] The slide 2 includes a vertical seat 21 (along Figure 2 The vertical seat 21 is positioned between the two guide rails 11. Second ball grooves (not shown) are defined on either side of the vertical seat 21. Each first ball groove 111 and the corresponding second ball groove combine to form a ball channel for accommodating the ball assembly. The transverse seat 22 is formed on the side of the vertical seat 21 away from the bottom wall 12 and is mounted above the top surfaces 112 of the two guide rails 11. The guard plate 23 is connected to the transverse seat body 22 and is located on the outside of the base 1. The guard plate 23 includes a side plate 231 and a bottom plate 232. The bottom plate 232 is closer to the bottom wall 12 than the transverse seat body 22, and the height of the bottom plate 232 in the vertical direction is lower than the top surface 112 of the guide rail; the side plate 231 includes an inner plate 2311 and an outer plate 2312 respectively connected to the two sides of the bottom plate 232 in the transverse direction.

[0039] In a preferred embodiment of the present invention, the cover plate 3 is separated from the slide 2 by a specified distance in the vertical direction. The cover plate 3 includes a web 31 and two wing plates 32. The web 31 is located on the side of the slide 2 away from the bottom wall 12 and extends along the longitudinal direction to cover the top surface 112 of the guide rail; the two wing plates 32 extend from the opposite sides of the web 31 to between the inner plate 2311 and the outer plate 2312 respectively.

[0040] In this embodiment, the web 31 of the cover plate 3 can cover the top of the linear motor module (including the top of the slide 2 and the top of the base 1), that is, cover the top gap (including the gap between the web 31 and the top surface 112 of the guide rail, and the gap between the web 31 and the top surface of the transverse seat 22). The wing plate 32 of the cover plate 3 can cover the side gap of the linear motor module, that is, cover the outer side of the guide rail 11 (the wing plate extends to the bottom of the top surface 112 of the guide rail), thereby preventing foreign matter from entering the interior of the linear motor module through the top and side gaps of the linear motor module. The cover plate 3 and the slide 2 are separated in the vertical direction and do not contact each other, avoiding friction between the cover plate 3 and the slide 2, and eliminating the need for frequent maintenance and replacement.

When the slide 2 slides near the end plate 4, the anti-collision blocks 24 can prevent direct collision between the slide 2 and the end plate 4, reducing damage to the structure of the slide 2 caused by the collision and extending the service life of the slide 2.

[0045] In this embodiment, the design of the annular channel transforms the contact between the ball group and the return groove, the reflux groove and the ball channel from sliding friction to rolling friction, thereby reducing the loss caused by friction and improving the accuracy and stability of the linear motor module. The ball group is evenly distributed and rolls in the annular channel, so that the slide 2 is more evenly stressed during the sliding process, reducing the deviation caused by uneven stress and further improving the positioning accuracy. Furthermore, technicians can set the number of annular channels according to actual needs, such as setting 2, 4 or more annular channels for each slide 2, which is not limited in this embodiment.
