Description

Linear motor module TECHNICAL FIELD

[0001] The present application relates to the technical field of linear motors, in particular to a linear motor module. BACKGROUND

[0002] The linear motor module generally comprises a base, a sliding seat in sliding connection with the base, and a mover assembly and a stator assembly for driving the sliding seat to slide. In order to prevent foreign matter from entering the interior of the linear motor module, a protective cover plate is usually added above the sliding seat to play a protective role and also ensure the appearance of the linear motor module.

[0003] In the existing semi-closed linear motor module, the protective cover plate has a certain gap with the sliding seat in order to avoid the shuttle of the sliding seat. Small parts or other foreign matter can enter the interior of the linear motor module through the gap on the side, which may cause jamming and damage to the motor. The protective effect is general and not suitable for scenes with more particles.

[0004] In the fully closed linear motor module, a steel belt passes through the sliding seat along the extension direction of the base. Except for the part passing through the sliding seat, the other part is close to the inner side of the base to achieve full sealing of the top of the base. The fully sealed linear motor module is not conducive to heat dissipation, which reduces the performance of the linear motor module. In addition, the interior of the sliding seat is curved, and a friction sheet made of wear-resistant material is attached to the curved surface. The friction sheet is used to support the steel belt when the sliding seat slides along the base and generate friction with the steel belt. The steel belt will deform after long-term use and needs to be frequently maintained and replaced. SUMMARY

[0005] To address the above problems, this invention provides a linear motor module, comprising: a base having: two guide rails spaced apart in the transverse direction and extending along a longitudinal direction perpendicular to the transverse direction, each guide rail having opposing first ball grooves; a bottom wall fixed and connected to the two guide rails in the transverse direction, the surfaces of the two guide rails facing away from the bottom wall being the top surfaces of the guide rails; and a slide block comprising: a vertical seat body located between the two guide rails, with second ball grooves correspondingly formed on both sides of the vertical seat body, each first ball groove and its corresponding second ball groove enclosing a ball channel for accommodating the ball assembly; and a transverse seat. The base consists of a body formed on the side of the vertical base away from the bottom wall, mounted on the top surface of the two guide rails; a guard plate connected to the transverse base and located on the outside of the base, the guard plate including a side plate and a bottom plate, the bottom plate being closer to the bottom wall than the transverse base; the side plate including an inner side plate and an outer side plate respectively connected to the two sides of the bottom plate in the transverse direction, the inner side plate being closer to the guide rail than the outer side plate; and a cover plate separated from the slide by a specified distance in the vertical direction, the cover plate including: a web plate located on the side of the slide away from the bottom wall and extending in the longitudinal direction to cover the top surface of the guide rail; and two wing plates extending from opposite sides of the web plate to between the inner side plate and the outer side plate, respectively.

[0006] According to this technical solution, the web of the cover plate can cover the top of the linear motor module (including the top of the slide and the top of the base), that is, cover the top gaps (including the gap between the web and the top surface of the guide rail, and the gap between the web and the top surface of the transverse seat). The wing plates of the cover plate can cover the side gaps of the linear motor module, that is, cover the outer side of the guide rail, thereby preventing foreign objects from entering the interior of the linear motor module from the top and side gaps. The cover plate and the slide are vertically separated and do not contact each other, avoiding friction between the cover plate and the slide, eliminating the need for frequent maintenance and replacement; at the same time, it does not affect the heat dissipation from the gap between the cover plate and the slide, ensuring the performance of the linear motor module.

The inlet of the inlet channel is located on the surface of the base plate away from the guide rail, and the outlet of the outlet channel is located on the vertical seat and is connected to the ball channel.

[0010] According to the technical scheme, the inlet of the inlet channel is located on the surface of the bottom plate far from the guide rail, oil can be injected through the inlet arranged on the bottom plate without disassembling the cover plate, and the convenience of maintenance of the linear motor module is improved.

[0011] In the optional technical scheme of the application, the ball lubricating channel further comprises: a first oil nozzle arranged on the end face of the inner side plate, the first oil nozzle comprising a first oil nozzle inlet and a first oil nozzle outlet in communication with each other, the first oil nozzle inlet being in communication with the outlet of the inlet channel inside the inner side plate, and the first oil nozzle outlet being located outside the slide; a second oil nozzle located on the same side of the slide as the first oil nozzle, the second oil nozzle comprising a second oil nozzle inlet and a second oil nozzle outlet in communication with each other, the second oil nozzle outlet extending into the interior of the slide, and the second oil nozzle inlet being located outside the slide; and an oil pipe having two ends in communication with the first oil nozzle outlet and the second oil nozzle inlet respectively.

[0012] According to the technical scheme, the first oil nozzle and the second oil nozzle are arranged on the end face of the slide and are used for changing the flow direction of the oil, cooperating with the inlet channel and the outlet channel inside the slide, reducing the need for grooving inside the slide, thereby saving the internal space of the slide and being conducive to ensuring the structural strength of the slide.

[0014] According to the technical scheme, the arrangement of the branch channels can simultaneously lubricate the ball groups in the main channels on both sides of the slide, simplifies the oil circuit design inside the slide, saves the internal space of the slide, and is conducive to ensuring the structural strength of the slide.

[0015] In the optional technical scheme of the application, the horizontal seat body, the vertical seat body and the guard plate are in an integrated structure.

[0016] According to the technical scheme, the horizontal seat body, the vertical seat body and the guard plate are formed in an integrated structure, which improves the integration, overall precision and quality of the slide structure, and improves the stability of the slide.

[0017] In the optional technical scheme of the application, the number of the slides is not less than 1.

[0018] According to the technical scheme, the arrangement of multiple slides improves the flexibility and efficiency of the linear motor module, and meets the diversified motion requirements.

[0039] In the present embodiment, the web plate 31 of the cover plate 3 can cover the top of the linear motor module (including the top of the sliding seat 2 and the top of the base 1), that is, cover the top gap (including the gap between the web plate 31 and the guide rail top surface 112, and the gap between the web plate 31 and the top surface of the transverse seat body 22), and 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 below the guide rail top surface 112), thereby preventing foreign matter from entering the interior of the linear motor module from the top and side gaps of the linear motor module.

The uniform distribution and rolling of the ball group in the annular channel make the force on the slide 2 more uniform during sliding, which reduces the deviation caused by uneven force and further improves the positioning precision. Further, the number of annular channels can be set according to actual needs, such as 2, 4 or more annular channels for each slide 2, which is not limited in the present embodiment.
