[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] See also Figure 1-8 An automatic cleaning device for foreign matter on the edge of a linear guide provided by an embodiment of the present invention includes a box body 1 that moves on the linear guide in the extension direction of the linear guide, and also includes: a scraper 2, which is arranged on the side of the linear guide, and the upper end is rotatably connected to the box body 1; a rotary seat 3, which is rotatably arranged on the side wall of the box body 1, and a roller brush 4 is rotatably connected thereto; an adjustment component, which is used to adjust the rotation of the scraper 2 to switch the direction toward the inside and outside of the linear guide; a linkage component, which is used to link the scraper 2 and the rotary seat 3, when the scraper 2 is toward the outside of the linear guide, the roller brush 4 is vertically attached to the side wall of the linear guide, and when the scraper 2 is toward the inside of the linear guide, the roller brush 4 is horizontally lifted to avoid the side wall of the linear guide.

[0034] Specifically, a pulley is provided at the bottom of the box body 1, which can slide on the linear guide rail; the box body 1 has a certain weight, so it is convenient to press stably on the upper surface of the linear guide rail; the width of the box body 1 in the directions of the two side surfaces corresponding to the linear guide rail is set close to the width of the linear guide rail; a handle is provided on the upper end of the box body 1, which is convenient for pushing the box body 1 to move along the extension direction of the linear guide rail. Preferably, the box body 1 can also be provided with an electrically driven pulley, or through an external guidance method, such as the box body 1 is connected to the slider on the linear guide rail, and moves with the slider to just move along the extension direction of the linear guide rail. One end of the scraper 2 in the horizontal direction is set as its rotating shaft, and the other end is set to match the shape of the side wall of the linear guide; the scraper 2 faces the inside and outside of the linear guide, that is, the scraper 2 faces the inside of the linear guide with the end matching the side wall of the linear guide. At this time, the scraper 2 just engages with the side wall of the linear guide and can perform scraping work; or the scraper 2 faces the outside of the linear guide with the end matching the side wall of the linear guide. At this time, there is a gap between one end of the rotating shaft of the scraper 2 and the side wall of the linear guide, and no scraping action will occur. The axial direction of the rotating seat 3 is horizontal and perpendicular to the extension direction of the linear guide, and the axial direction of the roller brush 4 is perpendicular to the axial direction of the rotating seat 3. Therefore, the rotation of the rotating seat 3 can drive the roller brush 4 to swing on the vertical plane parallel to the side wall of the linear guide. The swing range of this roller brush 4 is preferably 90°, that is, the roller brush 4 switches between the position of vertically fitting the side wall of the linear guide and the position of horizontally lifting to avoid the side wall of the linear guide; the roller brush 4 is preferably a sponge brush or a soft brush, which can be squeezed with the surface of the linear guide for cleaning. The adjusting component drives the scraper 2 to rotate to realize switching adjustment toward the inside and outside of the linear guide; the linkage component links the scraper 2 and the rotation of the rotary seat 3, and the position of the scraper 2 toward the outside of the linear guide corresponds to the position where the rotary seat 3 drives the roller brush 4 to vertically fit the side wall of the linear guide, and the position of the scraper 2 toward the inside of the linear guide corresponds to the position where the rotary seat 3 drives the roller brush 4 to be lifted horizontally to avoid the side wall of the linear guide. In actual use of the present technical solution, the cleaning agent is first sprayed on the linear guide rail, and then the box body 1 is correctly placed on the linear guide rail, and the scraper 2 is first facing the outside of the linear guide rail, and the roller brush 4 is vertically attached to the side wall of the linear guide rail. The box body 1 begins to move toward one end along the extension direction of the linear guide rail, and the roller brush 4 keeps rolling to clean the edge of the linear guide rail, while the recessed part of the side wall of the linear guide rail cannot be cleaned. Therefore, after the box body 1 has completely moved a whole section on the linear guide rail, the box body 1 switches the direction of movement, and the scraper 2 switches to the inside of the linear guide rail under the adjustment of the adjustment component to form a snap fit. At the same time, the linkage component links the rotating seat 3 to rotate to lift the roller brush 4 horizontally to avoid the side wall of the linear guide rail. Therefore, when the box body 1 moves to the other end along the linear guide rail, the scraper 2 can scrape off foreign matter on the edge of the linear guide rail, and the foreign matter accumulated will not stick to the roller brush 4, so it will not cause problems such as blockage and jamming.

[0035] Compared with the prior art, an automatic cleaning device for foreign matter on the edge of a linear guide rail proposed in an embodiment of the present invention connects a roller brush 4 by setting a rotating seat 3. When the scraper 2 is adjusted by the adjusting component toward the inner side of the linear guide rail, the linkage component links the rotating seat 3 to rotate to lift the roller brush 4 horizontally to avoid the side wall of the linear guide rail. Therefore, when the scraper 2 scrapes foreign matter off the edge of the linear guide rail, it is not easy for the foreign matter to accumulate and stick to the roller brush 4, thus avoiding problems such as blockage and jamming. When the scraper 2 is toward the outer side of the linear guide rail, the rotating seat 3 can switch the roller brush 4 to vertically fit the side wall of the linear guide rail, so that the roller brush 4 can clean the edge of the linear guide rail alone.

[0036] As the preferred technical solution of this embodiment, the adjustment component includes an adjustment shaft 5 rotatably arranged in the box body 1, and the adjustment shaft 5 is connected to the upper end of the rotating shaft of the scraper 2 through a bevel gear transmission. The adjustment shaft 5 can be spirally connected with an adjustment sleeve 6, and a sliding pin 7 is fixedly arranged on the adjustment sleeve 6. Specifically, the axial direction of the adjustment shaft 5 is horizontal and parallel to the axial direction of the rotating seat 3; a partition bin is arranged on the side wall of the box body 1, and the upper end of the rotating shaft of the scraper 2 and the end of the adjustment shaft 5 away from the inner side of the box body 1 both extend into the partition bin and are connected through a bevel gear transmission; the adjustment sleeve 6 only moves axially in the box body 1, and the axial movement of the adjustment sleeve 6 can trigger the spiral transmission to rotate the adjustment shaft 5; the sliding pin 7 is vertically connected to the upper end of the adjustment sleeve 6 and moves synchronously with the adjustment sleeve 6.

[0037] As a further preferred technical solution of this embodiment, two scrapers 2 are symmetrically arranged, and the corresponding two sliding pins 7 are movably connected to the same movable plate 9 through the inclined slide groove 8. The movable plate 9 is movably connected to the box body 1, and both ends of the movable direction are provided with push rods 10 that can movably extend out of the side wall of the box body 1. Specifically, the movable plate 9 moves horizontally in the box body 1 along the extension direction of the linear guide rail, and the movement of the movable plate 9 in the box body 1 is damped; the extension direction of the two ends of the inclined slide groove 8 and the movable direction of the sliding pin 7 have a certain angle; the push rods 10 at both ends of the movable plate 9 0 can extend out of the two ends of the box body 1 corresponding to the extension direction of the linear guide, and correspondingly: one push rod 10 is extended the longest, and the other push rod 10 is just received in the box body 1. Under the switching of the two push rods 10 in this extended state, the sliding pin 7 can correspond to the two ends in the inclined slide groove 8 respectively, and then correspond to the two ends of the axial movement of the adjustment sleeve 6 relative to the adjustment shaft 5, that is, respectively correspond to the rotation position of the scraper 2 toward the inside and outside of the linear guide; the two scrapers 2 are symmetrically arranged on the opposite sides of the box body 1, and are driven by the same movable plate 9 to synchronously switch toward the inside and outside of the linear guide.

[0038] As the preferred technical solution of this embodiment, the linkage assembly includes a sleeve 11 fixedly arranged on the rotary seat 3, the sleeve 11 penetrates and is rotatably connected to the box body 1, a linkage sleeve 12 which can be spirally connected to the sleeve 11 is fixedly arranged in the box body 1, the sleeve 11 can be axially moved, and the side wall of the adjusting sleeve 6 is connected to the sleeve 11 through a synchronizer 13 for synchronous axial movement. Specifically, one end of the sleeve 11 is arranged in the box body 1, and the other end penetrates and extends out of the side wall of the box body 1 to be coaxially connected to the rotating shaft position of the rotary seat 3; the linkage sleeve 12 is relatively fixed in the box body 1, and the sleeve 11 is spirally driven relative to the linkage sleeve 12 by axial movement, so that the sleeve 11 rotates synchronously; one end of the synchronizer 13 is fixedly connected to the outer wall of the adjusting sleeve 6, and the other end is sleeved on the outside of the sleeve 11, and a convex ring of a limited synchronizer 13 is provided on the outside of the sleeve 11, thereby ensuring that the sleeve 11 moves axially synchronously with the adjusting sleeve 6.

[0039] When the scraper 2 scrapes dirt toward the inner side of the linear guide rail, the accumulated dirt will extend to both ends in the vertical direction, and then some dirt will overflow from the upper end of the scraper 2 and adhere to the upper side and edge of the linear guide rail, which requires secondary cleaning in the prior art. In addition, after the scraper 2 performs the scraping work, the surface is also adhered to dirt that needs to be cleaned for subsequent use.

[0040] In another embodiment of the present invention, two roller brushes 4 are arranged on the same side of the box body 1. When the scraper 2 is facing the outside of the linear guide, the two roller brushes 4 clamp the scraper 2, and when the scraper 2 is facing the inside of the linear guide, the two roller brushes 4 are arranged in a horizontally raised position to fit the upper edge of the linear guide. Specifically, when the scraper 2 is facing the outside of the linear guide, the roller brush 4 is in a position vertically fitting the side wall of the linear guide to clean the side wall of the linear guide. At the same time, two roller brushes 4 are arranged on the same side of the box body 1. The two roller brushes 4 can clamp the scraper 2, and the rolling direction of the roller brush 4 is set to roll close to one side of the scraper 2 toward the outside of the linear guide, so that the roller brush 4 can also clean the surface of the scraper 2; when the scraper When the plate 2 is facing the inner side of the linear guide, the roller brush 4 is in a horizontally raised position. During the switching process, the scraper 2 triggers the rotation of the adjusting shaft 5 through the axial movement of the adjusting sleeve 6 relative to the adjusting shaft 5. At the same time, the adjusting sleeve 6 drives the sleeve 11 to move axially relative to the linkage sleeve 12 through the synchronous member 13 to trigger the rotation of the sleeve 11. In addition, the axial movement of the sleeve 11 also drives the rotary seat 3 to approach the box body 1, thereby also driving the roller brush 4 to approach the upper edge of the linear guide. Under the setting of the rolling direction of the roller brush 4 above, the lower side of the roller brush 4 can roll outward to clean the upper edge of the linear guide, thereby preventing the dirt overflowed during the scraping process of the scraper 2 from causing secondary pollution to the upper side and edges of the linear guide.

[0041] Due to the above arrangement of the roller brush 4 clamping the scraper 2, there is an interference problem during the process of the linkage switching of the positions of the scraper 2 and the roller brush 4. The following solution is proposed to solve this problem.

[0042] In another embodiment of the present invention, a first sliding protrusion 14 is provided on the outer side of the adjusting shaft 5, and a first sliding groove 15 matching the first sliding protrusion 14 is provided on the inner side of the adjusting sleeve 6. A section of the first sliding groove 15 close to the scraper 2 is arranged in a spiral shape, and the other section is arranged to extend axially with the adjusting sleeve 6; a second sliding protrusion 16 is provided on the inner wall of the linkage sleeve 12, and a second sliding groove 17 matching the second sliding protrusion 16 is provided on the outer wall of the sleeve 11, a section of the second sliding groove 17 away from the rotating seat 3 is arranged in a spiral shape, and the other section is arranged to extend axially with the sleeve 11. Specifically, the first sliding protrusion 16 The sliding protrusion 14 is arranged on one end of the adjusting shaft 5 extending into the box body 1; when the scraper 2 is in a position facing the outside of the linear guide rail, the first sliding protrusion 14 corresponds to the end of the first sliding groove 15 away from the scraper 2, that is, the axial extension section in the first sliding groove 15, and at the same time, the second sliding protrusion 16 is located in the end of the second sliding groove 17 away from the rotating seat 3, that is, the spiral section in the second sliding groove 17; when the first sliding protrusion 14 slides relative to the spiral section of the first sliding groove 15, the second sliding protrusion 16 does not slide relative to the spiral section of the second sliding groove 17, and vice versa. In actual use of the present technical solution, when the scraper 2 is to be switched from the direction facing outside the linear guide to the direction facing inside the linear guide, the adjusting sleeve 6 is driven by the above sliding pin 7, inclined sliding groove 8, movable plate 9 and push rod 10 to make the adjusting sleeve 6 move axially toward the inside of the box body 1, then the first sliding protrusion 14 first slides in the axial extension section in the first sliding groove 15 and continuously approaches the spiral section, and the scraper 2 first maintains the original direction, and at the same time, the adjusting sleeve 6 drives the sleeve 11 to move axially into the box body 1 through the synchronous member 13, and the second sliding protrusion 16 slides relative to the spiral section of the second sliding groove 17 to make the sleeve 11 rotate, and the sleeve 11 drives the rotating seat 3 and the roller on the rotating seat 3 The brush 4 rotates and lifts upward to no longer clamp the scraper 2. When the roller brush 4 is lifted to a horizontal position to avoid the side wall of the linear guide, the first sliding protrusion 14 begins to enter the spiral section of the first sliding groove 15, and the second sliding protrusion 16 also begins to enter the axial extension section of the second sliding groove 17. Then, the scraper 2 rotates to switch to the inside of the linear guide, while the rotary seat 3 maintains its position, thereby avoiding interference between the scraper 2 and the roller brush 4; conversely, when the adjustment sleeve 6 is driven to move in the reverse direction, the scraper 2 rotates and switches first. After the scraper 2 switches to the outside of the linear guide, the rotary seat 3 drives the roller brush 4 to rotate downward to re-clamp the scraper 2 in the vertical position, and no interference occurs.

[0043] In another embodiment of the present invention, a driving component for driving the roller brush 4 to roll is provided in the box body 1. Specifically, under the drive of the driving component, the two roller brushes 4 on the same side roll in opposite directions, specifically: when the roller brush 4 clamps the scraper 2, the rolling direction of the roller brush 4 is set to roll toward the outside of the linear guide rail close to the side of the scraper 2; when the roller brush 4 is lifted horizontally, the lower side of the roller brush 4 can roll outward to clean the upper edge of the linear guide rail; the above rolling direction of the roller brush 4 remains unchanged.

[0044] As a preferred technical solution of this embodiment, the driving assembly includes a motor 18 installed in the box body 1, and the output end of the motor 18 is connected to the driving shaft 19 through a bevel gear transmission. The end of the driving shaft 19 rotates and passes through the sleeve 11 to extend into the rotating seat 3, and a first bevel gear 20 is provided for synchronous rotation. One end of the rotating shaft of the roller brush 4 is rotatably connected to the rotating seat 3 and is coaxially connected to a second bevel gear 21 meshing with the first bevel gear 20. Specifically, the motor 18 is preferably a through-type double-headed output end, which is arranged between the two driving shafts 19 to drive the two driving shafts 19 to rotate in opposite directions; the two corresponding roller brushes 4 on both sides of the box body 1 are connected to the same driving shaft 19, and the first bevel gears 20 and the second bevel gears 21 on both sides are symmetrically arranged. The two opposing roller brushes 4 roll in opposite directions; the sleeve 11 is sleeved on the drive shaft 19 to satisfy axial movement and rotation, and does not affect the driving of the roller brush 4 by the drive shaft 19; a key block 22 is provided on the inner side of the first bevel gear 20, and a key groove 23 matching the key block 22 is provided on the drive shaft 19; a cavity is provided in the rotary seat 3, and the first bevel gear 20 and the second bevel gear 21 are provided in the cavity and maintain meshing transmission; the arrangement of the key block 22 and the key groove 23 enables the first bevel gear 20 to rotate synchronously with the drive shaft 19, and does not affect the movement of the first bevel gear 20 with the rotary seat 3, and the drive shaft 19 can penetrate the first bevel gear 20 to move relatively in the rotary seat 3, satisfying the need for the sleeve 11 to drive the rotary seat 3 to approach the box body 1.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
