[0010] The first dustproof component has clearance openings at both ends to cooperate with the two guide rails respectively.

[0011] In one embodiment, the first dustproof component includes a dustproof part and a first connecting part. The dustproof parts of the two first dustproof components are arranged opposite to each other and enclose the slider plate to form the dustproof space. The dustproof part extends along the first direction and the two opposite ends of the dustproof part are provided with the clearance opening. The first connecting part is connected to the slider plate.

[0012] In one embodiment, the slider plate is provided with a mounting groove, and the first connecting portion is located in the mounting groove.

[0013] In one embodiment, the first dustproof component includes a rigid substrate and an adhesive layer, the adhesive layer covering at least a portion of the outer surface of the rigid substrate, and the adhesive layer is provided at least in the area where the clearance opening is provided.

[0014] In one embodiment, the rigid substrate is made of metal.

[0015] And / or, where the first dustproof component includes a dustproof part and a first connecting part, the dustproof part is provided with the adhesive layer.

[0016] In one embodiment, the slider assembly further includes a timing belt retainer, which is disposed on the surface of the slider plate where the roller is located, and the guide rail mechanism further includes a timing belt, which is fixed to the timing belt retainer.

[0017] The first dustproof component has a through hole extending along the second direction, and the through hole is used to pass through the synchronous belt.

[0018] In one embodiment, the dustproof structure includes a second dustproof component, which is disposed on the side surface of the slider plate on which the roller is located, and extends along a portion of the circumference of the roller to form an open-loop structure. The open-loop structure, the slider plate, and the guide rail enclose the dustproof space, and the opening of the open-loop structure serves as the exposure port.

[0019] The roller is provided with partial structures of the second dustproof component on both sides along the second direction, and the clearance openings are provided at both ends of the second dustproof component.

[0020] In one embodiment, the second dustproof component is made of plastic.

[0021] And / or, the second dustproof component includes an open-loop portion and a second connecting portion, the open-loop portion extending circumferentially along a portion of the roller, the second connecting portion being connected to the edge of the open-loop portion near the slider plate, and being disposed opposite to and connected to the slider plate.

The dustproof structure, slider plate, and track enclose a dustproof space, within which the roller is positioned to prevent debris and waste from adhering to its rolling surface. Part of the roller's rolling surface can be exposed through an opening in the dustproof space, allowing it to roll along the guide rail during sliding engagement. In this case, the rolling surface at the exposed opening is blocked by the guide rail, further preventing impurities from adhering to this area. As the slider assembly slides along the track, the dustproof structure also scrapes away debris and waste adhering to the track, giving the guide rail mechanism a self-cleaning function and preventing the accumulation of impurities on the track after long-term use, which could affect the sliding of the slider assembly.

[0050] This utility model proposes a guide rail mechanism 1000.

[0051] See also Figure 1 , Figure 5 , Figure 8 as well as Figure 11 In one embodiment of the present invention, the guide rail mechanism 1000 includes a track 200 and a slider assembly 100. The slider assembly 100 is slidably disposed on the track 200. The slider assembly 100 includes a slider plate 10, a dustproof structure 20 and two rollers 30. The dustproof structure 20 is disposed on the slider plate 10 and forms a dustproof space 23 with the slider plate 10. The dustproof space 23 has an exposure opening 24 on one side along the first direction X. The rollers 30 are rotatably connected to the slider plate 10 and are located in the dustproof space 23. Part of the rolling surface of the rollers 30 is exposed in the exposure opening 24 and rolls with the track 200.

[0052] The guide rail mechanism 1000 proposed in this application is formed by combining a slider assembly 100 and a track 200. The track 200 has a guide rail 201 extending along a second direction Y. The slider assembly 100 includes a slider plate 10 and a roller 30 disposed on the slider plate 10. When the slider assembly 100 is engaged with the track 200, the roller 30 is engaged with the guide rail 201 in a rolling manner. When the slider assembly 100 slides along the track 200, the roller 30 rolls on the guide rail 201, so that there is rolling friction between the slider assembly 100 and the track 200, thereby reducing the friction between the slider assembly 100 and the track 200 and improving the stability of the sliding process.

[0053] Optionally, the track 200 may include a guide rail 201. In this case, the slider assembly 100 includes a roller 30 or at least two rollers 30 arranged along the second direction Y, which roll in cooperation with the guide rail 201. The second direction Y intersects the first direction X. Alternatively, the track 200 may include two guide rails 201 arranged side by side along the first direction X. In this case, the slider assembly 100 may include a roller 30 located between the two guide rails 201 or at least two rollers 30 arranged along the second direction Y, with each roller 30 rolling in cooperation with both guide rails 201 simultaneously. Alternatively, the slider assembly 100 may include two rollers 30 arranged along the first direction X, with each roller 30 corresponding to and rolling in cooperation with one of the two guide rails 201. The two rollers 30 may be located between the two guide rails 201, or the two guide rails 201 may be located between the two rollers 30; no limitation is made here.

[0054] In this embodiment, a dustproof structure 20 is provided on the slider assembly 100. The dustproof structure 20, the slider plate 10, and the track 200 enclose a dustproof space 23. The roller 30 is placed in the dustproof space 23 to prevent debris and waste residue from adhering to the rolling surface of the roller 30. When the slider assembly 100 slides along the guide rail 201, the dustproof structure 20 can also scrape away debris and waste residue adhering to the guide rail 201, giving the guide rail mechanism 1000 a self-cleaning function and preventing impurities from accumulating on the guide rail 201 after long-term use and affecting the sliding of the slider assembly 100. Part of the rolling surface of the roller can be exposed through the opening of the dustproof space so that it can roll with the guide rail when the slider assembly slides with the guide rail. At this time, the rolling surface at the exposed opening is blocked by the guide rail, which also prevents impurities from adhering to the rolling surface at this location.

[0055] In one embodiment, the track 200 includes a guide rail 201 extending along the second direction Y, the guide rail 201 being disposed opposite to the exposure opening 24, and the roller 30 rollingly engaging with the guide rail 201; the dustproof structure 20 has an avoidance opening 25 at its end along the first direction X, and the cross-sectional shape of the avoidance opening 25 is configured to mimic the cross-sectional shape of the guide rail 201.

[0056] In this embodiment, the dustproof structure 20 is provided with a relief opening 25 that is adapted to the shape of the guide rail 201, so that when the slider assembly 100 and the guide rail 201 slide together, the guide rail 201 can be adapted to the dustproof structure 20. This arrangement can ensure that there is not too large a gap between the dustproof structure 20 and the guide rail 201, thereby reducing the risk of impurities entering the dustproof space 23.

[0057] Optionally, the dustproof structure 20 may include two first dustproof components 21 arranged opposite each other along the second direction Y. The first dustproof components 21 are configured as plate-shaped or strip-shaped structures, such that at least two rollers 30 are disposed in the dustproof space 23 between the two first dustproof components 21. The first dustproof components 21 are provided with clearance openings 25 at both ends along the first direction X, for respectively adapting to the two guide rails 201. The dustproof structure 20 may also include multiple second dustproof components 22. The second dustproof components 22 are configured as open-loop structures with openings on one side, and the opening area forms an exposure opening 24. Multiple second dustproof components 22 can correspond one-to-one with multiple rollers 30, with each roller 30 located in the dustproof space 23 formed by one second dustproof component 22. Alternatively, at least two rollers 30 arranged along the length direction of the guide rail 201 (i.e., the second direction Y) can be located in the same dustproof space 23 formed by the same second dustproof component 22.

[0058] See also Figures 2 to 5 In one embodiment, the track 200 includes two guide rails 201 arranged side by side along the first direction X, and the dustproof space 23 has two exposed openings 24 arranged back to back; the dustproof structure 20 includes two first dustproof components 21, which are respectively disposed on both sides of the slider plate 10 along the second direction Y and are arranged opposite to each other, and the two first dustproof components 21 and the slider plate 10 form a dustproof space 23. The second direction Y intersects the first direction X, and the first dustproof components 21 are provided with clearance openings 25 at both ends along the first direction X to cooperate with the two guide rails 201 respectively. Both rollers 30 are disposed in the dustproof space 23.

[0059] In this embodiment, the dustproof structure 20 includes two first dustproof components 21 arranged opposite each other along the second direction Y. The first dustproof components 21 can form a non-removable integrated structure with the slider plate 10, for example, by integral injection molding, welding connection, etc.; the first dustproof components 21 can also be installed on the slider plate 10 by at least one method such as bolt connection, bonding, snap connection, etc. The first dustproof components 21 can be set as, but not limited to, a plate structure or a strip structure. Both ends of the first dustproof components 21 are provided with clearance openings 25. When the slider assembly 100 is engaged with the guide rail 201, the clearance openings 25 at both ends of the first dustproof components 21 are respectively adapted to the two guide rails 201. The multiple rollers 30 on the slider assembly 100 are all located in the dustproof space 23 formed by the two first dustproof components 21 and the slider plate 10, which can reduce the number of parts in the slider assembly 100, simplify the overall structure, reduce assembly steps, and improve ease of use.

[0060] Please see Figure 5 and Figure 6 In one embodiment, the first dustproof component 21 includes a dustproof part 211 and a first connecting part 212. The dustproof parts 211 of the two first dustproof components 21 are arranged opposite to each other and enclose the slider plate 10 to form a dustproof space 23. The dustproof part 211 extends along the first direction X. The two opposite ends of the dustproof part 211 are provided with clearance openings 25. The first connecting part 212 is connected to the slider plate 10.

[0061] In this embodiment, the first dustproof component 21 includes a dustproof portion 211 for forming a dustproof space 23 with the slider plate 10. When the slider assembly 100 is combined with the guide rail 201, the clearance opening 25 at the end of the dustproof portion 211 is adapted to the guide rail 201. The first connecting portion 212 of the first dustproof component 21 is connected to the slider plate 10, which can be, but is not limited to, at least one connection method such as bolt connection, snap-fit, or adhesive connection. This arrangement allows the first dustproof component 21 to effectively prevent dust and clean the guide rail 201 through the dustproof portion 211, and also improves the connection strength and overall structural stability of the slider assembly 100 through the better connection between the first connecting portion 212 and the slider plate 10.

[0062] Please see Figure 5 In one embodiment, the slider plate 10 is provided with a mounting groove 11, and the first connecting part 212 is located in the mounting groove 11.

[0063] In this embodiment, the first connecting part 212 is installed in the mounting groove 11 provided in the slider plate 10. This not only limits the first connecting part 212 to improve the positional stability of the first dustproof component 21 installed in the slider plate 10, but also prevents the first dustproof component 21 from protruding from the slider plate 10 in the second direction Y, or reduces the structural size of the first dustproof component 21 protruding from the slider plate 10 in the second direction Y, thereby reducing the length of the slider assembly 100 along the second direction Y.

[0064] Please see Figure 7 In one embodiment, the first dustproof component 21 includes a rigid substrate 213 and an adhesive layer 214. The adhesive layer 214 covers at least a portion of the outer surface of the rigid substrate 213, and the adhesive layer 214 is provided at least in the area where the clearance opening 25 is provided.

[0065] In this embodiment, the first dustproof component 21 includes a rigid substrate 213 and an adhesive layer 214. The rigid substrate 213 can be made of metal, rigid plastic, or other rigid materials to improve the structural strength of the first dustproof component 21. The adhesive layer 214 is provided on the outside of the rigid substrate 213. The adhesive layer 214 can be made of rubber, silicone, foam, or other materials. With this arrangement, as the slider assembly 100 slides along the guide rail 201, the first dustproof component 21 can scrape away debris and other impurities attached to the guide rail 201. The adhesive layer 214 can effectively remove impurities and reduce the risk of wear on the guide rail 201 caused by the first dustproof component 21. Optionally, the adhesive layer 214 can cover the entire outside of the rigid substrate 213, or it can only cover part of the structure of the rigid substrate 213.

[0066] In one embodiment, the rigid substrate 213 is made of metal; wherein, the metal material can be, but is not limited to, steel, stainless steel, aluminum alloy, etc., and the rigid substrate 213 made of metal has high structural strength.

[0067] Please see Figure 7 In one embodiment, when the first dustproof component 21 includes a dustproof part 211 and a first connecting part 212, the dustproof part 211 is provided with an adhesive layer 214.

[0068] In this embodiment, the first dustproof component 21 includes a dustproof part 211 for enclosing a dustproof space 23 with the slider plate 10, and a first connecting part 212 connected to the slider plate 10; wherein, a rigid substrate 213 forms the inner core of the dustproof part 211 and the first connecting part 212, and an adhesive layer 214 covers the outer side of the rigid substrate 213 forming the inner core of the dustproof part 211; with this configuration, the first connecting part 212 is made entirely of rigid material, which can better connect and fit with the slider plate 10, improving the connection strength and stability.

[0069] Please see Figure 5and Figure 11 In one embodiment, the slider assembly 100 further includes a timing belt fixing buckle 40, which is disposed on the surface of the slider plate 10 where the roller 30 is located.

[0070] In this embodiment, the slider assembly 100 is driven by the timing belt 300 assembly to slide along the track 200; the timing belt 300 can be connected to the timing belt fixing buckle 40 provided on the slider assembly 100 so that the slider assembly 100 can slide along the track 200 when the timing belt 300 moves.

[0071] Please see Figure 1 and Figure 6 In one embodiment, the first dustproof component 21 is provided with a through hole 215 extending along the second direction Y, and the through hole 215 is used to pass through the timing belt 300.

[0072] In this embodiment, the slider assembly 100 slides along the track 200 driven by the timing belt assembly. A through hole 215 is provided on the first dustproof component 21, through which the timing belt 300 can pass to connect with the slider plate 10. Optionally, a connecting channel 216 communicating with the through hole 215 can be provided on the first dustproof component 21. The connecting channel 216 extends to the edge of the first dustproof component 21 away from the slider plate 10, so that the timing belt 300 can enter and exit the through hole 215 along the connecting channel 216, improving the ease of assembly and disassembly. The width of the connecting channel 216 can be smaller than the width of the through hole 215, so that the timing belt 300 can be stably positioned in the through hole 215 without slipping into the connecting channel 216.

[0073] Please see Figures 8 to 11 In one embodiment, the dustproof structure 20 includes a second dustproof component 22, which is disposed on the side surface of the slider plate 10 where the roller 30 is located, and extends along a portion of the circumference of the roller 30 to form an open-loop structure. The open-loop structure and the slider plate 10 enclose a dustproof space 23, and the opening of the open-loop structure serves as an exposure opening 24. The roller 30 is provided with partial structures of the second dustproof component 22 on both sides along the second direction Y, and both ends of the second dustproof component 22 are provided with clearance openings 25.

[0074] In this embodiment, the dustproof structure 20 includes at least two second dustproof components 22, which can correspond one-to-one with multiple rollers 30, with each roller 30 located in a dustproof space 23 formed by a second dustproof component 22. In some embodiments, the slider assembly 100 includes two rows of rollers 30 arranged along a first direction X, with each row of rollers 30 including at least two rollers 30 arranged along a second direction Y. Alternatively, at least two rollers 30 arranged along the length direction of the guide rail 201 (i.e., the second direction Y) can be located in the same dustproof space 23 formed by the same second dustproof component 22, which is not limited here. The clearance openings 25 at both ends of the second dustproof component 22 are used to adapt to the same guide rail 201.

[0075] In one embodiment, the second dustproof component 22 is made of plastic. This design allows the second dustproof component 22 to be lighter and reduces the risk of wear and tear on the guide rail 201.

[0076] Please see Figure 11 In one embodiment, the second dustproof component 22 includes an open-loop portion 221 and a second connecting portion 222. The open-loop portion 221 extends circumferentially along a portion of the roller 30. The second connecting portion 222 is connected to the edge of the open-loop portion 221 near the slider plate 10 and is disposed opposite to and connected to the slider plate 10.

[0077] In this embodiment, the second dustproof component 22 includes an open ring portion 221 and a second connecting portion 222. The open ring portion 221 surrounds the periphery of the roller 30, and the second connecting portion 222 is disposed opposite to and connected to the slider plate 10. It can be connected by bolts, adhesives, or other means. By setting the second connecting portion 222, the connection strength and stability between the second dustproof component 22 and the slider plate 10 can be improved.

[0078] Optionally, in some embodiments, the dustproof structure 20 may include both a first dustproof component 21 and a second dustproof component 22 to improve the dustproof effect; the specific arrangement of the first dustproof component 21 and the second dustproof component 22 will not be described in detail here.

[0079] In one embodiment, the surface structure of the roller 30 is made of plastic.

[0080] This configuration can reduce the weight of the roller 30, and can prevent the roller 30 from wearing against the guide rail 201, thus avoiding the generation of dust, debris and other impurities. It can also reduce the noise of the slider assembly 100 sliding along the guide rail 201.

[0081] Please see Figure 1 and Figure 8In one embodiment, the track 200 includes a connecting plate 202 and two guide rails 201, the two guide rails 201 being connected to opposite sides of the connecting plate 202 along the first direction X; the slider assembly 100 includes two rollers 30 arranged along the first direction X, the two rollers 30 being located between the two guide rails 201, and the two rollers 30 being in rolling engagement with the two guide rails 201 respectively.

[0082] In this embodiment, the track 200 of the guide rail mechanism 1000 includes two guide rails 201 arranged opposite to each other. The two guide rails 201 are connected to each other by a connecting plate 202 to form an integral structure. The track 200 can be integrally formed, such as integral extrusion molding, integral injection molding, bending molding, etc. Alternatively, the connecting plate 202 and the guide rail 201 can be connected as one piece by welding, bolting, etc., which is not limited here. The roller 30 of the slider assembly 100 is disposed between the two guide rails 201. The slider plate 10 is located on the side of the roller 30 facing away from the connecting plate 202. With this arrangement, the connecting plate 202 can also shield the roller 30, which plays a role in dust prevention. Thus, the roller 30 is located in the dustproof space 23 formed by the connecting plate 202, the guide rail 201, the slider plate 10, and the dustproof assembly, which better prevents debris and other impurities from adhering to the rolling surface of the roller 30, thereby improving the stability of the slider assembly 100 sliding along the track 200.

[0083] Since the guide rail mechanism 1000 proposed in this application can adopt all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0084] Please see Figure 9 and Figure 10 In one embodiment, the dustproof structure 20 and the track 200 are spaced apart, and the gap between the dustproof structure 20 and the track 200 is set to 0.1mm to 0.15mm.

[0085] In this embodiment, the dustproof structure 20 and the track 200 are spaced apart to avoid sliding friction between the dustproof structure 20 and the track 200 during the sliding process of the slider assembly 100 relative to the track 200, thereby reducing the resistance encountered by the slider assembly 100 during the sliding process and improving the stability of the sliding process; and it can also prevent the dustproof structure 20 and the track 200 from wearing each other.

[0086] Specifically, the gap D between the dustproof structure 20 and the track 200 is set to 0.1mm to 0.15mm. The value of gap D can be 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, 0.15mm, or any value between 0.1mm and 0.15mm. The gap between the dustproof structure 20 and the track 200 is not less than 0.1mm to ensure that there is no sliding friction between the dustproof structure 20 and the track 200. The gap between the dustproof structure 20 and the track 200 does not exceed 0.15mm to prevent large particles of debris from entering the dustproof space 23 along the gap between the dustproof structure 20 and the track 200 and coming into contact with the roller 30, thus ensuring a good dustproof effect.

[0087] Please see Figure 1 and Figure 8 In one embodiment, the connecting plate 202 is provided with a drain hole 2021.

[0088] In this embodiment, the drain hole 2021 is provided so that debris and impurities falling into the inner side of the track 200 can be discharged from the drain hole 2021. These debris can be scraped to the location of the drain hole 2021 by the dustproof structure 20 or other structures on the slider assembly 100 during the sliding of the slider assembly 100 along the track 200.

[0089] This application also proposes a processing equipment, including a machine base, a guide rail mechanism 1000 and a moving part. The specific structure of the guide rail mechanism 1000 is as described in the aforementioned embodiment. The track 200 of the guide rail mechanism 1000 is provided on the machine base. The moving part is connected to the slider plate 10 of the guide rail mechanism 1000.

[0090] In this embodiment, the machine base serves as the supporting foundation for the processing equipment and can be used to install structures such as the guide rail mechanism 1000 and drive components. The drive components can be configured as, but are not limited to, a synchronous belt 300 drive structure, a cylinder or hydraulic cylinder push structure, a motor lead screw drive structure, etc., to drive the slider assembly 100 to slide along the track 200, thereby causing the moving parts to slide. The moving parts can be the processing head of the processing equipment. For example, the processing head can be, but is not limited to, a laser head, a print head, a tool assembly, etc. For example, if the processing head is configured as a laser head, the processing equipment is a laser processing equipment, and the laser head can emit laser light for laser cutting, laser welding, laser marking, laser engraving, laser cleaning, and other processing operations; the processing head can also be configured as a print head, such as a 3D print head or an inkjet print head, in which case the processing equipment is a 3D printer or an inkjet printer; the processing equipment can also be a machining equipment, with the processing head configured as a tool assembly having at least one processing tool such as a milling cutter or a drill bit.

[0091] Alternatively, the moving part can be other structures. For example, in the processing equipment, a first slide rail and a second slide rail with intersecting extension directions are provided. The processing head is slidably mounted on the second slide rail, and the second slide rail is slidably mounted on the first slide rail. In this case, the moving part can be the second slide rail, the track 200 of the guide rail mechanism 1000 is set as the first slide rail, and the second slide rail is connected to the slider assembly 100. Of course, the moving part can be any component in the processing equipment that needs to move, and there is no limitation here.

[0092] The specific structure of the guide rail mechanism 1000 is as described in the above embodiments. Since the processing equipment proposed in this application can adopt all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0093] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
