Description

Technical Field

[0001] The invention relates to the technical field of linear modules, and in particular to a dust and water proof structure of a linear module. Background Art

[0002] At present, linear modules are modular linear motion devices in the field of automation industry. Linear modules have the characteristics of high motion precision and easy installation and use. Therefore, linear modules have been widely promoted and used.

[0003] Authorization announcement number CN221525372U discloses a dust cover support structure of a linear module, which specifically discloses that it includes a base, a guide rail, a slider, a slide seat, a dust cover, a support rod and a linear drive mechanism; the front and rear ends of the base are respectively a first baffle and a second baffle; the guide rails are provided with two and the two guide rails are symmetrically installed on the top of the base; the sliders are provided with two and the two sliders can be moved forward and backward and are respectively installed on the two guide rails; the dust cover is spaced and covered on the two sliders and the two ends are respectively connected to the first baffle and the first baffle. The two baffles are connected; the slide seat can be moved forward and backward and is covered on the dust cover plate at intervals, and the two sides of the slide seat are respectively connected to the outer sides of the two sliders; the linear drive mechanism is installed on the base, and the output end of the linear drive mechanism is connected to the first slider, so that the linear drive mechanism can drive the slide seat and the second slider to achieve synchronous forward and backward movement through the first slider; the support rod is installed on the top of the base, and the top of the support rod is connected to the bottom surface of the dust cover plate to prevent the dust cover plate from deforming and bending.

[0004] However, there is still room for improvement in the dust cover support structure of the above-mentioned linear module. For example, since the dust cover is spaced apart and covers the two sliders, and the two sides of the slider need to be connected to the outer sides of the two sliders respectively, there is a gap between the dust cover and the base, and such a gap can easily cause water or dust to enter the gap between the dust cover and the base during use of the linear module, which can easily cause damage to the linear module.

[0005] In addition, there are also some linear modules that are designed by setting a steel belt on the top of the dust cover, and the two sides of the slider are stretched out from the bottom of the steel belt to the outside of the steel belt and the dust cover, so that the slider can be connected to the slide seat and drive the slide seat to move. This structure actually forms a top seal structure on the dust cover by the steel belt. However, in actual use of this top seal structure, since water and dust usually flow to the lower place, the gap between the side of the slider and the steel belt is easily entered by water and dust, that is, this design still has the problem of insufficient dust and water resistance.

[0006] Therefore, it is necessary to improve the existing technology. Summary of the invention

[0007] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a dustproof and water-resistant structure of a linear module, which adopts a side sealing design. Compared with the top sealing design, this design has better water-proof and dust-proof effects; at the same time, by providing two sealing belts and matching rollers, most of the gaps between the dust cover and the base can be covered by the vertical sealing belt. Even if water droplets or splashes accidentally spill onto the dust cover and the sealing belt, they will easily flow downward along the surface of the sealing belt and eventually flow downward along the side of the base.

The above arrangement can facilitate the disassembly and assembly of the sealing belt.

[0012] Furthermore, the first magnet and the second magnet are both in strip shape, and the lengths of the first magnet and the second magnet are both shorter than the length of the sealing belt. The above arrangement can ensure the stability between the magnet and the sealing belt.

[0013] Furthermore, first inwardly concave grooves are respectively provided on the two outer sides of the dust cover, and the first magnets located on the two sides of the dust cover are correspondingly embedded in the first grooves on the two sides of the dust cover; second inwardly concave grooves are respectively provided on the two outer sides of the base, and the second magnets located on the two sides of the base are correspondingly embedded in the second grooves on the two sides of the base. The above arrangement can improve the stability of the magnets.

[0014] Furthermore, the sealing belt is an elastic rubber belt, and each end of the sealing belt is connected to the side of the dust cover and the side of the base respectively. The above arrangement can provide another sealing belt structure.

[0015] Furthermore, one or two rollers are respectively provided on both sides of the slide seat; when one roller is respectively provided on both sides of the slide seat, the roller is located on the outside, front or rear of the side of the slider; when two rollers are respectively provided on both sides of the slide seat, one roller is distributed in front and rear of each side of the slider; the outer side surface of the roller is used to abut the sealing belt.

[0016] Furthermore, two rollers are arranged at the front and rear ends of both sides of the slide, and two rollers are arranged at the front and rear of each side of the slider; among the four rollers on the same side of the slide, the outer sides of the two rollers in the middle are used to abut against the sealing belt, and the inner sides of the other two rollers are used to abut against the sealing belt.

This design makes it easy for water droplets or splashes to flow down along the surface of the sealing belt when they accidentally spill onto the dust cover and the sealing belt, and eventually flow down along the side of the base.

[0036] The invention is further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the invention.

[0037] like Figure 1-Figure 11 As shown, a dustproof and water-resistant structure of a linear module includes a base 1, a dustproof cover plate 2, a slider, a slide rail, a slide seat 3, a sealing belt 4, a roller 5 and a linear drive mechanism 6.

[0038] like Figure 1-Figure 11As shown, a baffle 7 is respectively provided at the front and rear ends of the base 1; the slider is installed on the slide rail at the top of the base 1 so as to be movable forward and backward; the dust cover 2 is covered on the slider and the two ends are respectively connected to the two baffles 7; the two side edges of the slider extend out of the two sides of the dust cover 2 respectively and correspondingly; the slide 3 is movably arranged on the dust cover 2 with a gap, and the two sides of the slide 3 are respectively connected to the two side edges of the slider; the linear drive mechanism 6 is installed on the base 1, and the output end of the linear drive mechanism 6 is connected to the slider, so that the linear drive mechanism 6 can drive the slide 3 to move forward and backward synchronously through the slider.

[0039] like Figure 4 and Figure 6 As shown, in addition, rollers 5 that match the side of the slider are respectively arranged on both sides of the slider 3; two sealing belts 4 are arranged; the two sealing belts 4 are respectively connected to the two side surfaces of the dust cover 2 and the two side surfaces of the base 1, and the two sealing belts 4 are respectively correspondingly abutted on the rollers 5 on both sides of the slider 3; the sealing belt 4 can be used to seal the gap between the dust cover 2 and the base 1 to improve the dustproof and water-proof effect of the linear module. Of course, the sealing belt 4 needs to match the gap, and according to the length of the gap, the sealing belt 4 should also be set to a suitable length based on the length of the gap to ensure the sealing effect; the roller 5 can be used to open the sealing belt 4 corresponding to the side position of the slider to ensure that the end of the side of the slider can move normally outside the dust cover 2 without damaging the sealing belt 4. In addition, the amplitude of the roller 5 for its opening should not be too large according to the actual situation, and it is only necessary to ensure that the slider does not hit the sealing belt 4 when moving, so as not to reduce the dustproof and water-proof effect.

[0040] It can be seen that the present invention, by providing two sealing strips 4 and matching rollers 5, allows the gap between the dust cover 2 and the base 1 to be covered by the sealing strips 4, thereby improving the overall water resistance of the linear module and also improving the dustproof effect to a certain extent; and, since the sealing strips 4 are respectively connected to the two side surfaces of the dust cover 2 and the two side surfaces of the base 1, that is, the sealing strips 4 are used to seal the side surfaces of the linear module (i.e., side seals) and are in a vertical state as a whole. This design makes it easy for water droplets or splashes to flow down along the surface of the sealing strips 4 when they are accidentally spilled on the dust cover 2 and the sealing strips 4, and eventually flow down along the side surfaces of the base 1. Therefore, it is difficult for water to enter the interior of the linear module, that is, it largely ensures the safety of the linear module. The rollers 5 can be used to ensure the normal use of the slider and the sealing strips 4. Therefore, since the present invention is a side seal design, this design will have a better dustproof and water-resistant effect than the top seal design.

[0041] like Figure 3 and Figure 8As shown, preferably, in this embodiment, the sealing belt 4 is a steel belt; first magnets 8 are respectively provided on both side surfaces of the dust cover plate 2; second magnets 9 are respectively provided on both side surfaces of the base 1; the upper and lower sides of each sealing belt 4 are respectively and magnetically attracted to the first magnet 8 and the second magnet 9 to position the sealing belt 4. Therefore, the first magnet 8 and the second magnet 9 can be used to conveniently, quickly and stably fix the sealing belt 4 to prevent it from loosening. Of course, the purpose of fixing the sealing belt 4 with magnets is also that this design can conveniently and quickly disassemble and assemble the sealing belt 4 to improve the efficiency of disassembling and assembling the magnets.

[0042] like Figure 3 and Figure 8 As shown, in this embodiment, in order to ensure the stability between each magnet and the sealing belt 4, the first magnet 8 and the second magnet 9 are both selected to be arranged in a strip shape, and because the roller 5 needs to open the sealing belt 4, the length of the first magnet 8 and the second magnet 9 is smaller than the length of the sealing belt 4, so that the first magnet 8 and the second magnet 9 and the two sealing belts 4 are better matched. However, those skilled in the art should know that the first magnet 8 and the second magnet 9 can also be arranged to be longer than the sealing belt 4 if necessary.

[0043] like Figure 3 and Figure 8 As shown, preferably, in order to further improve the stability of the magnet, the two outer sides of the dust cover 2 are respectively provided with first grooves 10 concave inwardly, and the first magnets 8 located on both sides of the dust cover 2 are correspondingly embedded in the first grooves 10 on both sides of the dust cover 2; in addition, the two outer sides of the base 1 are respectively provided with second grooves 11 concave inwardly, and the second magnets 9 located on both sides of the base 1 are also correspondingly embedded in the second grooves 11 on both sides of the base 1. Therefore, since the magnets are installed in the grooves, their stability can be improved, so the positioning of the magnets is very stable, and thus the stability of the sealing belt 4 can be guaranteed to a certain extent. In addition, since the first magnet 8 and the second magnet 9 are both in the shape of strips, the first groove 10 and the second groove 11 are also in the shape of strips. However, those skilled in the art should know that the shapes of the first magnet 8, the second magnet 9, the first groove 10 and the second groove 11 can also be set to be block-shaped, and it is only necessary to set their number to a plurality of uniformly distributed ones, which will not be further described here.

[0044] like Figure 3 As shown, preferably, the two outer side surfaces of the dust cover 2 and the two outer side surfaces of the base 1 are both vertical planes, and the sealing belt 4 is also correspondingly vertically arranged, so that the sealing belt 4, the side surfaces of the dust cover 2 and the side surfaces of the base 1 are all conducive to diverting water downward to prevent water from entering the interior of the linear module.

[0045] In other embodiments, the sealing belt 4 can also be set as an elastic rubber belt. In this case, the sealing belt 4 can be fixed by connecting the ends of the sealing belt 4 to the side of the dust cover 2 and the side of the base 1, for example, bolts can be used for fixing, that is, magnets are not used to fix the sealing belt 4. Then, the deformation elasticity of the sealing belt 4 can be used to be stretched open by the roller 5 and automatically reset.

[0046] For the roller 5, the outer side surface of the roller 5 is preferably set to protrude outward from the outer side surface of the slider, that is, the outer side surfaces of the roller 5 on both sides of the slide seat 3 correspondingly protrude from the two side surfaces of the slider, so that the roller 5 is not easily hit by the slider when the sealing belt 4 is stretched open.

[0047] like Figure 6 As shown, in this embodiment, two rollers 5 are respectively arranged at the front and rear ends of both sides of the slide 3, and two rollers 5 are distributed in front and rear of each side of the slide; among the four rollers 5 on the same side of the slide 3, the outer sides of the two rollers 5 located in the middle are used to abut the sealing belt 4, so that the sealing belt 4 can be normally stretched by the rollers 5; and the inner sides of the other two rollers 5 are used to abut the sealing belt 4, so that the two rollers 5 can be used to press the sealing belt 4, so as to avoid the two rollers 5 used to stretch the sealing belt 4 to stretch the entire sealing belt 4 too much or make the sealing belt 4 loose, resulting in poor dustproof and waterproof. Therefore, through the above arrangement, the two rollers 5 located in the middle of the four rollers 5 on the same side of the slide 3 can be used to stretch the corresponding area of ​​each sealing belt 4, and then the two rollers 5 located at the front and the back can be used to press the front and rear ends of the area, so as to avoid the sealing belt 4 being stretched too much or loose, thereby ensuring the use effect of the sealing belt 4.

[0048] It should be noted that, in other embodiments, one or two rollers 5 may be respectively provided on both sides of the slide 3. When one roller 5 is respectively provided on both sides of the slide 3, the roller 5 may be located outside, front and back, or rear of the side of the slider. When two rollers 5 are respectively provided on both sides of the slide 3, a roller 5 is distributed on the front and back or rear of each side of the slider. Specifically, the rollers 5 under the above structure all use their outer sides to abut against the sealing belt 4.

[0049] like Figure 4 , Figure 6 and Fig.11As shown, in this embodiment, two mounting seats 12 are also included; the two mounting seats 12 are respectively mounted on the two outer sides of the slide 3; a mounting groove 20 extending forward and backward is provided on the side of each mounting seat 12 facing the dust cover plate 2; a connecting rod 18 is provided in each roller 5, and the upper and lower ends of each connecting rod 18 are respectively connected to the upper and lower side surfaces of the mounting groove 20, so that the roller 5 can be rotatably embedded in the mounting groove 20, and of course, the sealing belt 4 is also inserted in the mounting groove 20. It can be seen that the roller 5 is connected to the slide 3 through the mounting seat 12. Therefore, the roller 5 can be conveniently positioned by using the setting of the two mounting seats 12, and since the roller 5 is mounted on the mounting seat 12, when the roller 5 is inspected, maintained or replaced, the mounting seat 12 can be directly disassembled and then the roller 5 is inspected, maintained or replaced, thereby avoiding the need to disassemble the slide 3 and other components, and the process is simple and fast. Of course, the mounting seat 12 can also cover the portion of the sealing belt 4 opened by the roller 5 to a certain extent, so as to reduce the probability of water and dust entering this position.

[0050] In addition, it should be noted that the rolling direction of the roller 5 is the same as the length direction of the sealing belt 4 to ensure the smoothness of the rotation of the roller 5 .

[0051] like Figure 3 As shown, preferably, a drainage groove 13 penetrating the front and rear ends of the base 1 is provided on both sides of the top surface of the base 1; the two drainage grooves 13 are respectively located on the inner sides of the two sealing strips 4 and are covered by the dust cover 2. Therefore, after the two drainage grooves 13 are provided, if the sealing strip 4 is damaged, if water flows into the linear module through the gap between the dust cover 2 and the base 3, the water will first flow into the drainage groove 13, and then be discharged to the two ends of the base 1 through the drainage groove 13. That is, the provision of the drainage groove 13 ensures the drainage efficiency in the linear module, avoids water accumulation inside it, and thus protects the internal components.

[0052] like Figure 8 and Fig. 9 As shown, in this embodiment, the slide rail includes a first slide rail 14 and a second slide rail 15 which are symmetrically arranged; the slider includes a first slider 16 and a second slider 17 which are respectively mounted on the first slide rail 14 and the second slide rail 15; the output end of the linear drive mechanism 6 can be used to connect with the first slider 14 or the second slider 15; the outer sides of the first slider 16 and the second slider 17 extend out of the two sides of the dustproof sliding cover 2 and are respectively connected to the two sides of the slide seat 3. Therefore, the linear drive mechanism 6 can simultaneously drive the first slider 16, the second slider 17 and the slide seat 3 to move through one of the sliders.

[0053] like Figure 4 and Fig.10As shown, in this embodiment, the outer sides of the first slider 16 and the second slider 17 are respectively formed as a wing 19, and the thickness of the wing 19 should be set to be slightly smaller than the width of the gap between the dust cover 2 and the base 1. At the same time, in order to facilitate the connection of the slide 3, the two sides of the slide 3 are respectively connected to the wing 19 on the first slider 14 and the second slider 15 by bolts. In addition, for the first slider 16 and the second slider 17, both sides can also be set as wings, so that one of the wings can be used to connect with the linear drive mechanism 6.

[0054] Preferably, the dust cover plate 2 is in an upward convex arc shape.

[0055] In this embodiment, the linear drive mechanism 6 is a linear motor located between the first slide rail 14 and the second slide rail 15; the stator of the linear motor is mounted on the base 1, and the mover of the linear motor is arranged on the stator so as to be movable forward and backward; the mover is connected to the inner side wing of the first slider 16. Therefore, when the mover of the linear motor moves, it can drive the first slider 16, the slide 3 and the second slider 17 in sequence, thereby realizing the forward and backward movement of the slide 3. Since the linear drive mechanism 6 is a prior art, it will not be described in detail here.

[0056] The specific use principle of the present invention is introduced below to facilitate understanding of the present invention:

[0057] First, after all components are installed, the linear drive mechanism 6 is started so that the linear motor drives the first slider 16, the slide 3 and the second slider 17 to slide. During the movement of the slide 3, each roller 5 will move synchronously, so that the position to which the roller 5 moves will slightly open the sealing belt 4 at the corresponding position, so that the side edges of the two sliders will not be blocked during movement, and the side edges of the sliders will not hit the sealing belt 4 during movement, causing damage to the sealing belt 4; and, after the roller 5 leaves, the corresponding positions of the two sealing belts 4 will be attracted by the magnet and adsorbed on the first magnet 8 and the second magnet 9, that is, reset, so as to continue to seal the gap.

[0058] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
