Description

Technical Field

[0001] A linear drive module, particularly a linear drive module with a dust-proof member. Background Art

[0002] Generally, a linear drive module will achieve the effects of sealing and dust-proofing by closely attaching a dust-proof strip made of a soft material such as rubber or plastic to the slide rail. Regarding the assembly of the dust-proof strip, generally, the dust-proof strip is inserted from one end cap at one end of the slider along the length direction of the linear drive module to the end cap at the other end for assembly, or, along a direction orthogonal to the length direction, the dust-proof strip is pressed and assembled onto the linear drive module. However, the cross-sectional shape of the common dust-proof strip is asymmetric. No matter which assembly method is used, it is necessary to first confirm the cross-sectional shape of the dust-proof strip corresponding to the assembly groove to confirm the assembly direction during assembly. Therefore, it cannot be assembled arbitrarily. Moreover, due to the asymmetric cross-sectional shape, during manufacturing, for example, during injection or extrusion, the cooling shrinkage amounts of each part are inconsistent, making it difficult to control the processing accuracy. Further, due to the asymmetric cross-sectional shape of the dust-proof strip, it is necessary to separately mold for different cross-sectional shapes, and the mold repair difficulty is also relatively high. Summary of the Utility Model

[0003] In view of this, according to an embodiment, a linear drive module is provided, including a slider body, two end caps, and at least two dust-proof members. The slider body has its length direction set as the first direction, width direction as the second direction, and thickness direction as the third direction, and the first direction, second direction, and third direction are perpendicular to each other. The two end caps are respectively disposed at two opposite ends of the slider body in the first direction, and each end cap has at least two assembly grooves correspondingly arranged in the second direction. Each assembly groove extends through the end cap along the first direction, and each assembly groove has a contact surface, a clamping portion, and an assembly surface. The clamping portions are respectively connected to the contact surface and the assembly surface. The contact surface and the assembly surface are opposite surfaces, and the minimum distance between them in the fourth direction is less than the maximum distance of the clamping portion in the fourth direction. At least two dust-proof members extend along the first direction. One end of each dust-proof member in the first direction is assembled in the assembly groove of one of the end caps. The other end of each dust-proof member in the first direction is assembled in the assembly groove of the other end cap. Each dust-proof member has a dust-proof member body, a first contact portion, and a second contact portion. The first contact portion and the second contact portion are respectively located on opposite sides of the dust-proof member body perpendicular to the first direction, and respectively protrude from the dust-proof member body in the fourth direction of the dust-proof member body, and have symmetrical shapes.

[0004] In some embodiments, the end cap has a through groove penetrating the first direction inside, and the through groove has two end cap inner surfaces in the second direction of the end cap, and the two assembly grooves are correspondingly arranged on the two end cap inner surfaces.

[0005] In some embodiments, the slider body has an inner track groove running through the first direction. The track groove has two inner surfaces of the slider body in the second direction of the slider body and forms an opening in the third direction. The slider body further includes two outer retainers respectively disposed on the inner surfaces of the slider body and adjacent to the opening. Each outer retainer has a receiving groove running through in the first direction and corresponding to the assembly groove. When the opposite ends of each dust-proof member are respectively assembled into the assembly grooves of the two end caps, a part of each dust-proof member is received in the corresponding receiving groove.

[0006] In some embodiments, at least two dust-proof members are four, and at least two assembly grooves are four. The slider body further includes an inner retainer disposed on the side of the track groove of the slider body opposite to the opening. The inner retainer has two support portions correspondingly disposed in the second direction, and each support portion extends in the first direction. Two of the assembly grooves are correspondingly disposed on the end caps for the two support portions. When the opposite ends of two of the dust-proof members are respectively assembled into the assembly grooves on the two end caps corresponding to the support portions, the first contact portions of the two dust-proof members respectively abut against a support portion. When the opposite ends of the other two dust-proof members are respectively assembled into the assembly grooves on the two end caps corresponding to the receiving grooves, the first contact portions of the other two dust-proof members are respectively received in the receiving grooves correspondingly.

[0007] In some embodiments, the slider body has an inner track groove running through the first direction. The track groove has two inner surfaces of the slider body in the second direction of the slider body and forms an opening in the third direction. The slider body further includes an inner retainer disposed on the side of the track groove of the slider body far from the opening. The inner retainer has two support portions correspondingly disposed in the second direction, and each support portion extends in the first direction. When the opposite ends of each dust-proof member are respectively assembled into the assembly grooves of the two end caps, the first contact portion abuts against the support portion.

[0008] In some embodiments, each support portion continuously extends from one of the end caps to the other end cap.

[0009] In some embodiments, each support portion extends from one side of one of the end caps to the other side of the other end cap in a manner having a plurality of intervals.

[0010] In some embodiments, when the dust-proof member is assembled into the assembly groove, the first contact portion is received in the clamping portion, the dust-proof member body abuts against the abutting surface, and the second contact portion is exposed outside the assembly groove.

[0011] In some embodiments, the dimension of the dust-proof member body in the fourth direction is smaller than the minimum distance between the abutting surface and the assembly surface of the assembly groove in the fourth direction.

[0012] In some embodiments, the dimension of the dust-proof member body in the fourth direction is equal to the minimum distance between the abutting surface and the assembly surface of the assembly groove in the fourth direction.

[0013] In some embodiments, the assembly surface of the assembly groove protrudes towards the abutment surface and abuts against the dust-proof member body of the dust-proof member.

[0014] In some embodiments, the end cap is disposed on the outer surface of the second assembly groove in the second direction.

[0015] In some embodiments, the hardness of the dust-proof member body of each dust-proof member is greater than the hardness of the first contact portion and the second contact portion.

[0016] In some embodiments, the cross-sections of the first contact portion and the second contact portion are circular, oval, triangular or rectangular.

[0017] In summary, according to an embodiment of the present application, a linear drive module is provided, in which the first contact portion and the second contact portion with symmetrical shapes are provided on opposite sides of the dust-proof member. When the dust-proof member is assembled into the corresponding assembly groove on the end cap, it can be fixed in the assembly groove through one of the contact portions, and the other contact portion abuts against an external component to close the gap, achieving both the assembly and dust-proof effects. Further, since the first contact portion and the second contact portion have symmetrical shapes, the assembly and dust-proof functions can be achieved regardless of whether the first or second contact portion is used. For example, when the first contact portion is used as the assembly structure, the second contact portion can be used as the dust-proof structure, and when the first contact portion is used as the dust-proof structure, the second contact portion can be used as the assembly structure, that is, the first or second contact portion has both the assembly and dust-proof functions. Also, since the shapes of the first and second contact portions are symmetrical, it is more convenient for the user to assemble, and it is also easier to manufacture the dust-proof member. Moreover, as the usage time increases, one of the two contact portions may be worn. At this time, the dust-proof member can be taken out, and the other unworn contact portion can be used for assembly again to reduce the replacement rate of the dust-proof member, achieving the effects of environmental protection and waste reduction.

[0060] Please refer to Figures 1 to 4 . Figure 1 Is a perspective view of a linear drive module according to a first embodiment. Figure 2 Is a front view of the linear drive module applied to a slide rail according to a first embodiment. Figure 3 Is Figure 2 A partial enlarged view of the linear drive module in Figure 4 Is a front view of the linear drive module applied to a slide rail according to a first embodiment. A linear drive module 100 includes a slider body 110, two end covers 130 and at least two dust-proof parts 150.

[0061] For convenience of subsequent description, the direction extending along the length direction in the slider body 110 is set as the first direction Z (i.e., Figure 1 The Z-axis direction in Figure 1 ), the direction extending along the width direction of the slider body 110 is set as the second direction X (i.e., Figure 1 The X-axis direction in

[0062] Two end caps 130 are respectively disposed at two opposite ends of the slider body 110 in the first direction Z. Since the two end caps 130 have the same structure, only one of the end caps 130 will be described herein. In this embodiment, as Figure 1 shown, the end cap 130 is described by taking four assembly grooves 131 as an example. In actual application, the end cap 130 may also be provided with only the assembly grooves 131 located on the lower left and right sides to provide the most basic dust-proof effect. The two assembly grooves 131 located on the lower left and right sides are respectively described as assembly grooves 131A and 131B hereinafter (as Figure 2 shown), and the two assembly grooves 131A and 131B are correspondingly arranged in the second direction X. The two assembly grooves 131A and 131B are located on opposite sides and have the same structure. The assembly groove 131A on the left side in Figure 2 will be described hereinafter. As can be seen from Figures 1 to 3 , the assembly groove 131A extends through the end cap 130 along the first direction Z. As can be seen from Figure 3 , the assembly groove 131A has an abutting surface 1311A, a clamping portion 1312A and an assembly surface 1313A. The clamping portion 1312A is respectively connected to the abutting surface 1311A and the assembly surface 1313A, and the abutting surface 1311A and the assembly surface 1313A are opposite surfaces. As Figure 3 shown, the minimum distance between the abutting surface 1311A and the assembly surface 1313A in the fourth direction D is less than the maximum distance of the clamping portion 1312A in the fourth direction D. In this way, it is beneficial to the assembly of the dust-proof member 150 described later. The assembly structure will be described in detail later. In this embodiment, the fourth direction D is the direction perpendicular to the abutting surface 1311A.

[0063] Refer to again Figures 1 to 3. In this embodiment, a dust-proof member 150 is respectively assembled at each of the four assembly grooves 131, so there are a total of four dust-proof members 150. As described above, if only the two lower assembly grooves 131A and 131B are provided, only the two dust-proof members 150 corresponding to the two assembly grooves 131A and 131B are required. Here, the two dust-proof members 150 provided in the two assembly grooves 131A and 131B are respectively described as dust-proof members 150A and 150B hereinafter. The two dust-proof members 150A and 150B extend along the first direction Z, and the two dust-proof members 150A and 150B have the same structure. One of the dust-proof members 150A will be described hereinafter. One end of the dust-proof member 150A in the first direction Z is assembled in the assembly groove 131A of the end cover 130, and the other end of the dust-proof member 150A in the first direction Z is assembled in the assembly groove 131A of the other end cover 130. Regarding the assembly method of the dust-proof member 150, for example, the dust-proof member 150A can be inserted from one end cover 130 of the slider body 110 to the other end cover 130 along the first direction Z, so that both ends of the dust-proof member 150A in the first direction Z are respectively received in the assembly grooves 131A of the two end covers 130. Also, the two ends of the dust-proof member 150A in the first direction Z can be grasped, and the dust-proof member 150A can be pushed toward the two assembly grooves 131A along a direction orthogonal to the first direction Z, so that both ends of the dust-proof member 150A are snapped into the two assembly grooves 131A. Further, as Figures 1 to 3 shown, the dust-proof member 150A has a dust-proof member body 151A, a first contact portion 152A, and a second contact portion 153A. The first contact portion 152A and the second contact portion 153A are respectively located on opposite sides of the dust-proof member body 151A perpendicular to the first direction Z, and protrude from the dust-proof member body 151A in the fourth direction D of the dust-proof member body 151A, and have symmetrical shapes.

[0064] Thus, when the first contact portion 152A is assembled in the assembly groove 131A, the second contact portion 153A will protrude from the assembly groove 131A and abut against an external component (such as Figure 2 the slide rail 500 shown), and this can prevent dust or impurities from entering through the gap between the slider body 110 and the slide rail 500, or between the end cover 130 and the slide rail 500, affecting the movement of the slider body 110 on the slide rail 500. Also, as the linear drive module 100 moves along the slide rail 500, the second contact portion 153A will also continuously and tightly abut against the slide rail 500, continuously closing the gap to isolate the internal and external spaces, achieving the dust-proof effect.

[0065] In addition, the dust-proof member 150A of the linear drive module 100 is formed with a first contact portion 152A and a second contact portion 153A having symmetrical shapes. The user can assemble either contact portion into the assembly groove 131A. When assembling the dust-proof members 150A and 150B into the corresponding assembly grooves 131A and 131B on the two end caps 130, it can be fixed in the assembly grooves 131A and 131B through one of the contact portions. In this way, the effects of assembly and dust-proof are integrated by the dust-proof member 150A. The assembly is performed with the first contact portion 152A, and the second contact portion 153A abuts against an external component to close the gap. Also, if the second contact portion 153A is used for assembly, the first contact portion 152A can also abut against an external component to close the gap. That is, each structure of the first contact portion 152A and the second contact portion 153A can be used as a dust-proof structure and can also be used as an assembly structure. Also, due to the symmetrical first contact portion 152A and second contact portion 153A of the dust-proof member 150A, the user can assemble more conveniently without particularly paying attention to the assembly direction during assembly, which can increase the assembly speed and reduce the possibility of errors, and it is also easier to manufacture the dust-proof members 150A and 150B. Also, as the usage time increases, one of the first contact portion 152A and the second contact portion 153A may be worn. At this time, the dust-proof member 150A can be taken out and the other unworn contact portion can be used for assembly again to reduce the replacement rate of the dust-proof member 150A, achieving the effects of environmental protection and waste reduction.

[0066] Also, in this embodiment, the hardness of the dust-proof member body 151A is greater than the hardness of the first contact portion 152A and the second contact portion 153A. For example, the dust-proof member body 151A is made of, for example, metal or a polymer, and the first contact portion 152A and the second contact portion 153A are made of, for example, a polymer. In this embodiment, the polymer is, for example, plastic or rubber. In this way, while strengthening the structural strength, the first contact portion 152A and the second contact portion 153A are kept having the effect of being more easily deformable. In this way, when the contact portion abuts against the slide rail 500, it can closely contact the slide rail 500 through the deformation effect due to its flexibility to close the gap.

[0067] Regarding the assembly of the dust-proof member 150A, please refer to Figures 1 to 3。In this embodiment, taking the assembly of the first contact portion 152A as an example for illustration, similarly, since the two end caps 130 have the same structure, one of the end caps 130 is taken as an example, and the other end cap 130 will not be repeatedly described. When the dust-proof member 150A is inserted along the first direction Z into the assembly groove 131A or forced into the assembly groove 131A by applying force through the opening between the abutting surface 1311A and the assembly surface 1313A until the two ends of the dust-proof member 150A in the first direction Z are respectively assembled into the assembly grooves 131A of the two end caps 130, the first contact portion 152A is received in the locking portion 1312A, the dust-proof member body 151A abuts against the abutting surface 1311A, and the second contact portion 153A is exposed outside the assembly groove 131A. As Figure 3 shown, since the minimum distance between the abutting surface 1311A and the assembly surface 1313A in the fourth direction D is smaller than the maximum distance of the locking portion 1312A in the fourth direction D, if the size of the first contact portion 152A is greater than the minimum distance between the abutting surface 1311A and the assembly surface 1313A in the fourth direction D but smaller than the maximum distance of the locking portion 1312A in the fourth direction D, the first contact portion 152A will be blocked by the abutting surface 1311A and the assembly surface 1313A without receiving a force in an appropriate direction and thus cannot pass through, thereby preventing the first contact portion 152A from falling off the locking portion 1312A. In addition, the second contact portion 153A exposed outside the assembly groove 131A will continuously abut against the slide rail 500 to close the gap between the slide rail 500 and the linear drive module 100. Also, in this embodiment, the dimension of the dust-proof member body 151A in the fourth direction D is smaller than the minimum distance between the abutting surface 1311A and the assembly surface 1313A in the fourth direction D. When the second contact portion 153A abuts against the slide rail 500, the second contact portion 153A can deform or move toward Figure 3 the assembly surface 1313A side. In this way, space for the second contact portion 153A to move can be reserved, and it can also be avoided that if the tolerance is too large during the manufacture of the dust-proof member 150A, the contact between the second contact portion 153A and the slide rail 500 is too tight, resulting in too large relative sliding resistance between the two and affecting the operation of the linear drive module 100.

[0068] Refer again to Figure 1 and Figure 2 。In this embodiment, the end cap 130 internally has a through groove 132 penetrating in the first direction Z. The through groove 132 has two end cap inner surfaces 133A and 133B in the second direction X of the end cap 130, and the two end cap inner surfaces 133A and 133B are opposite surfaces. The two assembly grooves 131A and 131B are correspondingly arranged on the two end cap inner surfaces 133A and 133B.

[0069] Please refer to Figure 1 and Figure 4。In this embodiment, the slider body 110 has an orbital groove 111 penetrating in the first direction Z. The orbital groove 111 has two inner surfaces 112A and 112B of the slider body in the second direction X of the slider body 110, and forms an opening 113 in the third direction Y. The slider body 110 further includes two outer retainers 114A and 114B, and the two outer retainers 114A and 114B are respectively disposed on the inner surfaces 112A and 112B of the slider body and adjacent to the opening 113. Each of the outer retainers 114A and 114B has a receiving groove 1141A and 1141B penetrating in the first direction Z and corresponding to the assembly grooves 131A and 131B. From Figure 1 and Figure 4 it can be seen that the receiving grooves 1141A and 1141B are respectively located on the outer surfaces of the outer retainers 114A and 114B facing the orbital groove 111. In this embodiment, since the two outer retainers 114A and 114B have the same structure, one of the outer retainers 114A will be described below. When the two opposite ends of the dust-proof member 150A in the first direction Z are respectively assembled in the assembly grooves 131A of the two end caps 130, the first contact portion 152A in the middle section of the dust-proof member 150A in the first direction Z abuts against the corresponding receiving groove 1141A. Thus, by providing additional support for the dust-proof member 150A by the outer retainer 114A, it is possible to prevent the middle section of the dust-proof member 150A from sagging due to gravity and affecting the abutment between the dust-proof member 150A and the slide rail 500 and the sliding between the slider body 110 and the slide rail 500.

[0070] In this embodiment, the dust-proof member 150A is assembled on the assembly groove 131A adjacent to the opening 113, and the dust-proof member 150B is assembled on the assembly groove 131B adjacent to the opening 113. Thus, it is possible to prevent dust or foreign objects from entering the slide rail 500, but it is not limited thereto. As described above, in this embodiment, there are four dust-proof members 150, which will be described below as dust-proof members 150A, 150B, 150C, and 150D respectively, and the assembly grooves 131 on the end cap 130 also correspond to four, which will be described below as assembly grooves 131A, 131B, 131C, and 131D respectively. The assembly of the dust-proof members 150A and 150B and the assembly grooves 131A and 131B will not be repeated.

[0071] In this embodiment, from Figure 2 it can be seen that the assembly grooves 131C and 131D are located at one end away from the opening 113 relative to the assembly grooves 131A and 131B. And from Figure 1 matched with Figure 4It can be known that the slider body 110 further includes an inner retainer 115 disposed on the side of the track groove 111 of the slider body 110 opposite to the opening 113. The inner retainer 115 has two support portions 1151, 1152, which are correspondingly disposed in the second direction X, and each support portion 1151, 1152 extends along the first direction Z. Two assembly grooves 131C, 131D are correspondingly disposed for the two support portions 1151, 1152. When the opposite two ends of the dust-proof member 150C in the first direction Z are respectively assembled into the assembly groove 131C corresponding to the support portion 1151 on the two end caps 130, the first contact portion 152C of the dust-proof member 150C abuts against the support portion 1151. When the opposite two ends of the dust-proof member 150D in the first direction Z are respectively assembled into the assembly groove 131D corresponding to the support portion 1152 on the two end caps 130, the first contact portion 152D of the dust-proof member 150D abuts against the support portion 1152. In this way, the dust-proof members 150C, 150D are disposed on the opposite inner sides of the opening 113 to further enhance the dust-proof effect, and the inner retainer 115 provides additional support for the dust-proof members 150C, 150D, which can prevent the middle sections of the dust-proof members 150C, 150D from sagging due to gravity and affecting the abutment with the slide rail 500 and the sliding between the slider body 110 and the slide rail 500.

[0072] In this embodiment, two dust-proof members 150A, 150B are disposed adjacent to the opening 113, and two dust-proof members 150C, 150D are disposed on the inner side relatively far from the opening 113. In another embodiment, it is also possible to only dispose two dust-proof members 150A, 150B adjacent to the opening 113, or only dispose two dust-proof members 150C, 150D on the inner side relatively far from the opening 113.

[0073] Please refer to Figure 5 。 Figure 5 is a bottom view of a linear drive module according to a first embodiment. As Figure 5 shown, the support portions 1151, 1152 extend from one end cap 130 side to the other end cap 130 side in a manner having a plurality of intervals d, but it is not limited thereto. In another embodiment, the support portions 1151, 1152 continuously extend from one end cap 130 to the other end cap 130. Also, in another embodiment, the support portion 1152 can also be only disposed at the middle position in the first direction Z to prevent the middle sections of the dust-proof members 150C, 150D from sagging due to gravity.

[0074] The assembly groove 131 and the dust-proof member 150 can also have other embodiments. Figure 3 It is shown that the dimension of the dust-proof member body 151A in the fourth direction D is smaller than the minimum distance between the abutting surface 1311A and the assembling surface 1313A of the assembly groove 131A in the fourth direction D, but it is not limited thereto. Please refer to Figure 6 。 Figure 6Schematic diagram of the assembly groove of the linear drive module according to a second embodiment. In the second embodiment, the dimension of the dust-proof member body 151A in the fourth direction D (the thickness dimension of the dust-proof member body 151A) is substantially equal to the minimum distance between the abutting surface 1311A and the assembly surface 1313A of the assembly groove 131A in the fourth direction D. Thus, one side of the dust-proof member body 151A abuts against the abutting surface 1311A, and the assembly surface 1313A abuts against the other side of the dust-proof member body 151A. In this structure, the dust-proof member 150A can be more firmly clamped and assembled in the assembly groove 131A.

[0075] Also, Figure 3 The first contact portion 152A and the second contact portion 153A with a cross-sectional shape slightly elliptical are shown, but are not limited thereto. Please refer to Figure 7A and Figure 7B . Figure 7A Schematic diagram of the dust-proof member of the linear drive module according to a third embodiment. Figure 7B Schematic diagram of the dust-proof member of the linear drive module according to a fourth embodiment. In the third embodiment, the cross-sections of the first contact portion 152A and the second contact portion 153A can be triangular as shown in Figure 7A . Or, in the fourth embodiment, the cross-sections of the first contact portion 152A and the second contact portion 153A can be circular or other shapes as shown in Figure 7B . In other embodiments, they can also be any shape such as rectangular, as long as the first contact portion 152A and the second contact portion 153A are symmetric shapes.

[0076] Please refer to Figures 8 to 10 . Figure 8 Front view of the linear drive module applied to the slide rail according to a fifth embodiment. Figure 9 is Figure 8 Partial enlarged view of the linear drive module in Figure 10 Schematic diagram of the assembly groove of the linear drive module according to a sixth embodiment. In the fifth embodiment, the linear drive module 200 can also be applied to the slide rail 600 of the single-rail robot. In this embodiment, as shown in Figure 8 , the slide rail 600 of the single-rail robot is, for example, a slide rail 600 with a U-shaped cross-section. The linear drive module 200 is placed in the recessed position of the U-shaped slide rail 600 for sliding. In the fifth embodiment, the same structures as those in the first embodiment will not be described again.

[0077] As shown in Figure 8 and Figure 9As shown, in this embodiment, since the slide rail 600 is U-shaped with an opening facing upward, and the linear drive module 200 is also assembled and slides in the middle recessed position of the slide rail 600 from above, dust and the like are more likely to enter through the gaps on the left and right sides of the slide rail 600 where they come into contact with the linear drive module 200 after falling from above. Therefore, two assembly grooves 231A and 231B are provided on the outer surface of the end cover 230 in the second direction X, and both ends of each dust-proof member 250A and 250B are respectively assembled in the two assembly grooves 231A and 231B of the two end covers 230 along the first direction Z, thereby closing the gap between the linear drive module 200 and the slide rail 600 and preventing dust or foreign objects from entering from above. As Figure 9 shown, the assembly groove 231A is formed as a groove with a necking-down shape so that the dust-proof member 250A can be more firmly assembled in the assembly groove 231A, but it is not limited thereto. As Figure 10 shown, in the sixth embodiment, the assembly groove 231A can also be a slotted groove with a flat inner surface extending throughout.
