Description

Technical Field

[0001] This application relates to the field of linear modules, and more particularly to a slide assembly and a linear module. Background Technology

[0002] Linear modules, as core transmission components in automated equipment, are widely used in various precision motion transmission scenarios. Their operational stability and the lifespan of core components directly affect the overall equipment's working efficiency and operating costs, playing a crucial role in industrial production and other fields. Currently, the connection between the slide and slider in linear modules generally adopts an "L"-shaped structure design, where the force-transmitting end of the slide is assembled and fixed to the edge area of ​​the slider. This structural design means that the driving force transmitted by the slide cannot directly act on the force center of the slider, but is concentrated on the edge of the slider. When the linear module is running, the slide drives the slider in reciprocating motion or bears external loads. The offset force will generate a significant overturning moment at the edge of the slider. This overturning moment will cause uneven stress distribution between the slider and the guide rail, exacerbating localized wear on the internal transmission structure and contact surfaces of the slider. After long-term use, the slider is prone to problems such as decreased motion accuracy, jamming, and abnormal noise, ultimately significantly shortening the slider's lifespan and failing to meet the long-term stable operation requirements of automated equipment for transmission components.

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a slide assembly and a linear module.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides: A slide assembly having two perpendicular directions, a second direction, and a third direction, the slide assembly comprising: Carrier plate; The slide body has two slide bodies, which are disposed on the side of the carrier plate along the first direction.

Connecting plates are provided on both sides of the base plate facing the carrier plate along the second direction. The base plate and the connecting plates are integrally connected, and the connecting plates are fixedly connected to the carrier plate.

[0005] Furthermore, along the second direction, baffles are provided on the opposite sides of the two slide bodies.

[0006] Furthermore, along the second direction, mounting grooves are provided on the sides of the two slide bodies that are close to each other, and encoder reading heads are provided in the mounting grooves.

[0007] This application also provides a linear module having a first direction and a second direction that are perpendicular to each other, including: The slide assembly described in any of the above statements; A base is located on one side of the slide assembly along the first direction. A guide rail is provided on the base, and a slider is slidably disposed on the guide rail. The bottom plate of the slide body is connected to the slider. The mover has two parts, which are disposed along the second direction on the sides of the two slide bodies that are close to each other; The first stator is fixedly disposed on the base and disposed along the first direction on the side of the mover away from the carrier plate.

[0008] Furthermore, the linear module also has a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other; The base includes a fixed plate, on which a vertical plate is fixedly disposed on the side facing the slide assembly. The vertical plate extends along the third direction. Two moving parts are located on both sides of the vertical plate along the second direction. A cover plate is fixedly disposed on the side of the vertical plate away from the fixed plate.

[0013] Furthermore, a second protective cover is connected to both sides of the carrier plate along the third direction, and the side of the second protective cover opposite to the carrier plate is connected to the end plate.

[0014] This application integrates the base plate and connecting plate of the slide body, and the connecting plate is fixedly connected to the carrier plate. This allows the force from the carrier plate to be evenly applied to the base plate through the two connecting plates, and then vertically transmitted to the middle of the slider through the base plate.

[0024] This application provides a slide assembly, specifically, the slide assembly has a first direction Z, a second direction Y and a third direction X that are perpendicular to each other, and the slide assembly 100 includes a carrier plate 110 and a slide body 120.

[0025] There are two slide bodies 120. The slide bodies 120 are disposed on the side of the carrier plate 110 along the first direction Z. The two slide bodies 120 are spaced apart along the second direction Y. The slide body 120 includes a base plate 121. The side of the base plate 121 facing the carrier plate 110 is provided with connecting plates 122 on both sides along the second direction Y. The base plate 121 and the connecting plates 122 are integrally connected. The connecting plates 122 are fixedly connected to the carrier plate 110.

[0026] In the above, the first direction Z is the vertical direction, the second direction Y is the width direction of the slide assembly 100 (i.e., the longitudinal direction), and the third direction X is the length direction of the slide assembly 100 (i.e., the transverse direction).

[0027] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, the slide body 120 includes an integrally connected base plate 121 and connecting plate 122. The connecting plate 122 has two sides on the upper surface of the base plate 121, and the two connecting plates 122 are symmetrically arranged about the center line of the base plate 121, so that the base plate 121 and the two connecting plates 122 form a "U" shaped structure. The base plate 121 is fixedly connected to the carrier plate 110 through the two connecting plates 122. Specifically, the carrier plate 110 and the connecting plate 122 can be fixedly connected by bolts.

[0028] Understandably, the base plate 121 is connected to the slider at its bottom, and the middle position of the base plate 121 is connected to the slider. This allows the force from the carrier plate 110 to be evenly applied to the base plate 121 through the two connecting plates 122, and then vertically transmitted to the slider through the base plate 121. Consequently, the base plate 121 does not provide the slider with a rotational torque relative to the guide rail. At this time, the guide rail only bears the vertical pressure from the slider, and there is no rotational torque between the two, thereby reducing the wear between the guide rail and the slider.

[0029] In some embodiments, baffles 130 are provided on the opposite sides of the two slide bodies 120 along the second direction Y.

[0030] Please continue reading. Figure 1 , Figure 2 as well as Figure 3 As shown, in order to prevent external dust from entering the module through the gap under the slide body 120, a baffle 130 is fixedly installed on the outside of the slide body 120 to block it. Specifically, the baffle 130 is fixedly installed on the connecting plate 122 located on the outside, and the baffle 130 extends to the bottom plate 121 to block the gap on the bottom side.

[0031] In some embodiments, along the second direction Y, mounting grooves 101 are provided on the sides of the two slide bodies 120 that are close to each other, and an encoder reading head 140 is provided in the mounting grooves 101.

[0032] Please continue reading Figure 1 , Figure 2 as well as Figure 3 As shown, in order to prevent the encoder reading head 140 from being installed on the outside of the slide body 120 and thus increasing the width of the entire linear module, in this embodiment, the encoder reading head 140 is fixedly installed on one side of the two slide bodies 120 that are close to each other, that is, the encoder reading head 140 is installed inside the entire slide assembly. This not only meets the installation requirements but also reduces the width of the linear module to a certain extent, so that the width of the linear module meets the installation requirements.

[0033] This application embodiment also provides a linear module, which has a first direction Z and a second direction Y perpendicular to each other, as well as a third direction X. Specifically, the linear module includes a slide assembly 100, a base 200, a mover 300, and a first stator 410 as described above. The base 200 is located on the side of the slide assembly 100 along the first direction Z. A guide rail is provided on the base 200, and a slider is slidably arranged on the guide rail. The bottom plate 121 of the slide body 120 is connected to the slider. There are two movers 300, which are arranged along the second direction Y on the sides of the two slide bodies 120 that are close to each other. The first stator 410 is fixedly arranged on the base 200, and the first stator 410 is arranged along the first direction Z on the side of the mover 300 away from the carrier plate 110.

[0034] Please see Figure 4 and Figure 5 As shown, guide rails are fixedly installed on both sides of the upper surface of the base 200, and sliders are slidably installed on each guide rail. Each slider is fixedly connected to the slide body 120 on both sides of the bottom surface of the carrier plate 110, so that the carrier plate 110 and the slide body 120 can slide relative to the base 200 through the cooperation between the slider and the guide rail.

[0035] In this embodiment, the bottom center of the base plate 121 of the slide body 120 is fixedly connected to the slider, thereby preventing the slide body 120 from giving the slider a rotational torque, reducing the wear between the slider and the guide rail, and thus extending the service life.

[0036] Please continue reading. Figure 4 and Figure 5As shown, two adjacent slide bodies 120 are spaced apart on the bottom surface of the carrier plate 110 along the width direction of the linear module, and a mover 300 is fixedly installed on the base plate 121 where the two slide bodies 120 are close to each other. In order to enable the mover 300 to drive the slide body 120 and the carrier plate 110 to move relative to the base 200, a first stator 410 adapted to the mover 300 is fixedly installed on the base 200. The linkage between the mover 300 and the first stator 410 makes the mover 300 move relative to the base 200 along with the slide body 120 and the carrier plate 110.

[0037] It is understandable that fixing the two movers 300 to the base plates 121 of the two slide bodies 120 that are close to each other, that is, setting the movers 300 on the inside of the slide assembly 100, can improve the utilization of space and reduce the space occupied by the entire linear module.

[0038] In some embodiments, the base 200 includes a fixing plate 210, on which a vertical plate 220 is fixedly disposed on the side of the fixing plate 210 facing the slide assembly 100. The vertical plate 220 extends along a third direction X. Two movers 300 are located on both sides of the vertical plate 220 along a second direction Y. A cover plate 500 is fixedly disposed on the side of the vertical plate 220 away from the fixing plate 210. A second stator 420 is disposed on both sides of the cover plate 500 facing the side of the fixing plate 210 along the second direction Y. The second stator 420 is located on the side of the mover 300 away from the first stator 410.

[0039] Please continue reading. Figure 4 and Figure 5 As shown, in order to increase the driving force of the mover 300 to drive the slide body 120 and the carrier plate 110, a second stator 420 is also provided above the mover 300. Under the dual action of the first stator 410 and the second stator 420, the driving power of the mover 300 is increased.

[0040] In this embodiment, in order to install the second stator 420, an upright plate 220 is integrally fixed on the upper surface of the fixed plate 210, so that the cross section of the entire base 200 is "T" shaped to ensure the strength of the entire base 200. A cover plate 500 is fixedly installed on the top surface of the upright plate 220. The cover plate 500 extends along the width direction above the two movers 300. The second stator 420 corresponding to the mover 300 is fixedly installed on the side of the cover plate 500 facing the mover 300. That is, the mover 300 is located between the first stator 410 and the second stator 420.

[0041] Furthermore, the cover plate 500 not only provides mounting and fixing for the second stator 420, but also seals the top of the mover 300. At this time, the two slide bodies 120, the fixing plate 210 and the cover plate 500 define a space for accommodating the two movers 300, the two first stators 410 and the two second stators 420. The cover plate 500 closes the upper opening of the space to prevent external dust from entering the second stator 420, the mover 300 and the first stator 410 through the upper opening of the space, thereby achieving the function of sealing and protection. For example, both first stators 410 and both second stators 420 are magnetic tracks.

[0042] In some embodiments, the upright plate 220 has a plurality of uniformly distributed weight-reducing holes 221 extending through it in the third direction X.

[0043] Please continue reading Figure 4 As shown, in order to reduce the weight of the entire straight line, multiple weight-reducing holes 221 are made on the vertical plate 220, and the multiple weight-reducing holes 221 are evenly spaced along the length of the vertical plate 220.

[0044] In another embodiment, multiple weight-reducing grooves may be evenly distributed on the bottom surface of the fixing plate 210.

[0045] In some embodiments, the fixing plate 210 is provided with end plates 230 at both ends along the third direction X, and buffer members 231 are provided on the sides of the two end plates 230 facing each other.

[0046] See also Figure 4 When the carrier plate 110 and the slide body 120 move relative to the base 200, in order to prevent the slide body 120 and the carrier plate 110 from directly colliding with the end plates 230 at both ends of the fixed plate 210 and causing damage to the components, buffer members 231 are fixedly installed on the inner side of the two end plates 230, that is, on the side where the two end plates 230 are close to each other. The impact force is buffered by the buffer members 231 to prevent hard collision.

[0047] For example, the buffer 231 can be a hydraulic buffer or a rubber pad, etc., and the specifics are not limited here.

[0048] In some embodiments, a grating ruler 510 is provided on the side of the cover plate 500 facing one of the slide bodies 120 along the second direction Y.

[0049] Please see Figure 2 and Figure 4As shown, since the encoder reading head 140 needs to be used in conjunction with the grating ruler 510 to realize the position detection and determination of the carrier plate 110, and since the encoder reading head 140 is fixedly installed on the inner side of one of the slide bodies 120, the grating ruler 510 is fixedly installed on the side of the cover plate 500 facing the encoder reading head 140, so that the encoder reading head 140 and the grating ruler 510 can be used in conjunction.

[0050] In some embodiments, each slide body 120 is provided with a first protective cover 600 at both ends along the third direction X, and the end of the first protective cover 600 facing away from the slide body 120 is connected to the end plate 230.

[0051] See Figure 6 As shown, in order to prevent external dust from entering the module through the gap between the slide body 120 and the end plate 230, a first protective cover 600 is fixedly installed on the side of each slide body 120 facing the end plate 230, and the end of the first protective cover 600 away from the slide body 120 is fixedly connected to the end plate 230, thereby sealing the gap between the slide body 120 and the end plate 230. It can be understood that the two sides of the first protective cover 600 in the width direction abut against the side of the upright plate 220 and the upper surface of the fixed plate 210, respectively, to prevent external dust from entering the module through the gap between the first protective cover 600 and the upright plate 220 and the gap between the first protective cover 600 and the fixed plate 210, and causing damage to its internal components.

[0052] It is understandable that, since the linear module has two slide bodies 120 and each slide body 120 has two end faces, the first protective cover 600 in this embodiment has four, that is, each end face of the slide body 120 is connected to a first protective cover 600.

[0053] In some embodiments, the carrier plate 110 is connected to both sides of the third direction X with a second protective cover 700, and the side of the second protective cover 700 facing away from the carrier plate 110 is connected to the end plate 230.

[0054] See Figure 6 and Figure 7 As shown, in order to further prevent external dust from entering the module, a second protective cover 700 is provided between the carrier plate 110 and the two end plates 230. Specifically, the second protective cover 700 covers the space between the carrier plate 110 and the end plates 230, thereby further preventing dust particles from entering the module and achieving multiple protections to ensure the reliability and stability of the linear module during use.
