[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] A linear drive device is a power device that can drive an object to be moved to reciprocate in one direction. Generally speaking, a linear drive device includes a drive member, a track, and a linear slide. The drive member is used to provide power to drive the linear slide to slide along the extension direction of the track, and the linear slide is used to install the object to be moved, so that when the linear slide slides on the track, the object to be moved is driven to move with it.

[0052] When the linear slide in the related art slides on the track, under the conditions of high speed and high acceleration, the moving axis will generate a large force during movement, causing the pulley of the linear slide to vibrate easily, thereby affecting the stability of the linear slide during movement.

[0053] Therefore, based on the above considerations, in order to solve the problem of unstable movement of linear slides in the current industry, this application proposes a new type of linear slide. The linear slide innovatively designs the sliding carrier to include a first mounting portion, an elastic portion and a second mounting portion. The first mounting portion and the second mounting portion inherit the main function of the sliding carrier and are used to install the pulley, while the elastic portion can be used to generate elastic force when the linear slide is clamped on the track to form a preload between the pulley and the track without causing the elastic portion to yield, so as to ensure stable contact between the pulley and the track, making it difficult for the pulley to shake, thereby improving the stability of the linear slide during movement.

[0054] The linear slide proposed in this application is mainly used in linear drive devices. At the same time, the linear slide can also be used to install objects that need to be driven. For example, the object that needs to be driven can be a laser head for emitting laser in a laser processing device, so that the laser head can perform laser processing on different parts of the workpiece after following the movement of the sliding platform. Of course, the linear slide can also be installed on another linear drive device to realize the driving of the laser head in different directions through at least two linear drive devices.

[0055] Next, the structure of the linear slide proposed in this application is explained and illustrated by an embodiment. In one embodiment of this application, please refer to Figure 1 , Figure 2 as well as Figure 4 The linear slide 10 proposed in the present application includes a sliding carrier 11, a first pulley 13 and a second pulley 14. The sliding carrier 11 includes a first mounting portion 111, an elastic portion 112 and a second mounting portion 116 connected in sequence in the first direction. The elastic portion 116 can be elastically deformed when subjected to a force, so that the first mounting portion 111 and the second mounting portion 116 can be closer to or farther from each other in the first direction; the first pulley 13 is rotatably mounted on the first mounting portion 111; the second pulley 14 is rotatably mounted on the second mounting portion 116, and the rotation axes of the first pulley 13 and the second pulley 14 (such as Figure 1 , Figure 2 as well as Figure 4 The directions (as shown by the dotted lines in FIG. 1 ) all intersect with the first direction.

[0056] The sliding carrier 11 can provide a mounting position through the first mounting portion 111 and the second mounting portion 116 to install the pulley 13. At the same time, at least one of the first mounting portion 111 and the second mounting portion 116 can also be installed with the above-mentioned object to be driven, and then when the sliding carrier 11 slides along the extension of the track 30, the object to be driven is driven to slide accordingly. Among them, the first mounting portion 111 and the second mounting portion 116 can be a plate structure as described below, and of course can also be a block or column structure, etc., and the present application does not limit the specific structural form and shape of the first mounting portion 111 and the second mounting portion 116. The elastic part 112 in the sliding carrier 11 can be used to generate a reaction force by elastic deformation when subjected to an action force, so that the first mounting part 111 and the second mounting part 116 can be close to and away from each other, and then when the pulley 13 is abutted and assembled with the track 30, the reaction force generated by the elastic part 112 can be transmitted to the first pulley 13 and the second pulley 14 through the first mounting part 111 and the second mounting part 116, respectively, so that the first pulley 13 and the second pulley 14 can better abut the track 30, so that the pulley 13 and the track 30 can be stably abutted. At the same time, the first pulley 13 and the second pulley 14 can be close to and away from each other, so as to adjust the spacing between the pulleys 13 on the opposite sides of the sliding carrier 11 in the first direction, so as to adapt to the tracks 30 with different spacings and improve the stability of the installation of the linear slide 10. Among them, the elastic part 112 can be a plate structure with elastic deformation ability as described below, of course, it can also be a spring sheet or a spring structure, etc., and the present application does not limit the specific structural form of the elastic part 112. In addition, when the track 30 is extended in the horizontal direction, the first direction may be the up-down direction; when the track 30 is extended in the up-down direction, the first direction may be the horizontal direction. That is, the first direction may be perpendicular to the extension direction of the track 30. In addition, the direction of the reaction force generated by the elastic part 112 when deformed may be parallel to the first direction, or may form an acute angle with the first direction.

[0057] The first pulley 13 and the second pulley 14 can be used to abut against the track 30. Specifically, the first pulley 13 and the second pulley 14 can abut against two abutting surfaces in the track 30 that are opposite to each other, or abut against two abutting surfaces in the track 30 that are back-to-back, so as to realize the clamping of the linear slide 10 on the track 30. Further, the number of the first pulley 13 can be one, and of course it can also be two or more. When the number of the first pulleys 13 is at least two, the two first pulleys 13 can be arranged side by side along the second direction on the first mounting portion 111, and the second direction, the first direction and the direction of the rotation axis of the first pulley 13 intersect each other. Similarly, the number of the second pulley 14 can be one, and of course it can also be two or more. When the number of the second pulleys 14 is at least two, the two second pulleys 14 can be arranged side by side along the second direction on the second mounting portion 116. In addition, the number of the first pulleys 13 and the number of the second pulleys 14 can be the same, and of course they can also be different. In addition, the first pulley 13 and the second pulley 14 can be located on the same side of the sliding carrier 11, or they can be located on opposite sides of the sliding carrier 11. In addition, in order to improve the convenience of installing the first pulley 13 and the second pulley 13, the first pulley 13 can be fixed to the first mounting portion 111 by inserting a fastening screw 15 so that it can rotate in the circumferential direction and be limited in the direction of the rotation axis. The second pulley 14 can also be fixed to the second mounting portion 116 by inserting a fastening screw 15 so that it can rotate in the circumferential direction and be limited in the direction of the rotation axis. The rotation axis direction of the first pulley 13 is parallel to the rotation axis direction of the second pulley 14.

[0058] When the linear slide 10 of the present application is assembled on the track 30 , the first pulley 13 and the second pulley 14 abut against two abutment surfaces that are oppositely arranged in the track 30 , or two abutment surfaces that are back-to-back arranged, thereby achieving the clamping of the linear slide 10 on the track 30 . The sliding carrier 11 includes a first mounting portion 111, a second mounting portion 116 and an elastic portion 112 located between the first mounting portion 111 and the second mounting portion 116. The elastic portion 116 can be elastically deformed and generate a reaction force when subjected to an action force (for example, a force applied by a track, which force will not cause the elastic portion 112 to yield), so that the first mounting portion 111 and the second mounting portion 116 can approach and move away from each other. The first pulley 13 and the second pulley 14 are respectively mounted on the first mounting portion 111 and the second mounting portion 116, and the reaction force can be further transmitted to the first pulley 13 and the second pulley 14, ensuring that the first pulley 13 and the second pulley 14 can have a certain amount of pre-compression between the track 30, so that the first pulley 13 and the second pulley 14 can stably abut the track 30 in the positive and negative directions of the first direction, respectively, thereby improving the stability of the linear slide 10 during movement.

[0059] At the same time, the elastic part 112 also allows the spacing between the first pulley 13 and the second pulley 14 to be adjusted, so that the first pulley 13 and the second pulley 14 can adapt to the two abutment surfaces of the track 30 with different spacings, thereby facilitating the installation of the linear slide 10 on the track 30. Therefore, while improving the stability of the linear slide 10 during the movement, the convenience of installing the linear slide 10 on the track 30 is also improved.

[0060] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the elastic portion 112 includes at least one bend.

[0061] In this embodiment, the elastic part 112 includes at least one bend, so that the elastic part 112 can be compressed or expanded at the parts on both sides of the bend, so that the elastic part 112 has a good elastic deformation ability. In one embodiment, the elastic part 112 is a plate structure, so that the elastic part 112 has a good elastic deformation ability, and can also have relatively good rigidity and strength, so as to take into account the pre-compression effect between the pulley 13 and the track 30 and the stability of the sliding carrier 11, thereby facilitating further improving the stability of the linear slide 10 moving on the track 30. At the same time, the plate structure can also make the structure of the elastic part 112 relatively simple, and can be well connected with the first mounting part 111 and the second mounting part 116, thereby improving the convenience of manufacturing the sliding carrier 11. In addition, the plate structure can also make the overall volume of the elastic part 112 relatively small, which is conducive to reducing the overall volume of the sliding carrier 11, so as to reduce the overall volume of the linear slide 10, thereby improving the convenience of its subsequent installation in a limited space.

[0062] Among them, the elastic part 112 can be a combination of a first plate body 113, a second plate body 114 and a third plate body 115 as described below, thereby forming two bends; of course, it can also be a combination of only two plates arranged at an angle, thereby forming a bend; or it can be a combination of four or more plates connected in sequence and arranged at an angle, so that a bend can be formed at the connection between each two adjacent plates, and at this time, the openings of each two adjacent angles can be arranged back to back in the first direction; or, the elastic part 112 can also be a combination of an arc plate, an arc plate and flat plates located at opposite ends of the arc plate, or a combination of at least two arc plates connected in sequence. The present application does not limit the structural form of the elastic part 112.

[0063] Please refer to Figure 1 and Figure 2In one embodiment of the present application, the elastic portion 112 includes a first plate body 113, a second plate body 114 and a third plate body 115 that are bent. The first plate body 113 and the third plate body 115 are respectively connected to the opposite ends of the second plate body 114 in the first direction, and a bend is formed at the connection between the first mounting portion 111 and the second plate body 114; the first mounting portion 111 is connected to one end of the first plate body 113 away from the second plate body 114, and the second mounting portion 116 is connected to one end of the third plate body 115 away from the second plate body 114.

[0064] In this embodiment, the elastic part 112 is configured to include a first plate body 113, a second plate body 114 and a third plate body 115. On the one hand, the number of plates included in the elastic part 112 can be relatively small, which is conducive to simplifying the structure of the elastic part 112 and improving the convenience of its manufacture. On the other hand, a relatively large spacing can be provided between the first plate body 113 and the third plate body 115, so that the elastic part 112 can have a larger deformation space, so as to further enhance the elastic deformation capacity of the elastic part 112, thereby facilitating the convenience of driving the elastic part 112 to undergo elastic deformation when the linear slide 10 is subsequently installed, so that the pulley 13 is pressed against the track 30 under the action of the large reaction force given by the elastic part 112, and further improving the stability of the subsequent linear slide 10 during the movement process. At the same time, the convenience of installing the linear slide 10 on the track 30 is further improved. The first plate 113 and the third plate 115 may be perpendicular to the second plate 114 to further improve the regularity of the elastic portion 112 and thus improve the manufacturing convenience and elastic deformation capability.

[0065] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the first plate 113 and the third plate 115 extend in the same direction along the rotation axis of the pulley 13 from the connection end with the second plate 114 .

[0066] In this embodiment, the first plate 113 and the third plate 11 are extended from the connection end with the second plate 114 toward the same side, so that the elastic part 112 can be enclosed to form a U-shaped structure. At this time, the elastic part 112 will not occupy too much space in the direction of the rotation axis of the pulley 13, which is conducive to improving the compactness of the distribution of each plate in the elastic part 112, so as to reduce the overall volume of the elastic part 112. At the same time, a mechanical structure foundation can also be provided so that the first pulley 13 and the second pulley 14 can correspond better, thereby facilitating the linear slide 10 to uniformly resist the force on the opposite sides through the pulley 13 and the track 30, so as to further improve the stability of the linear slide 10 clamped on the track 30. Of course, it should be noted that the present application is not limited to this. In other embodiments, the first plate 113 and the third plate 11 can also be extended in opposite directions from the connection end with the second plate 114. In other embodiments, the elastic portion 112 may include a C-shaped structure, an S-shaped structure, a V-shaped structure, or a Z-shaped structure, or a combination of these structures, in addition to the U-shaped structure.

[0067] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the first pulley 13 is installed on a side of the first mounting portion 111 facing the second plate 114 , and the second pulley 14 is installed on a side of the second mounting portion 116 facing the second plate 114 .

[0068] In this embodiment, the side of the first mounting portion 111 facing the second plate body 114 can be enclosed with the first plate body 113 to form a first step 11a, and the first pulley 13 can be installed in the first step 11a. The side of the second mounting portion 116 facing the second plate body 114 can be enclosed with the third plate body 115 to form a second step 11b, and the second pulley 14 can be installed in the second step 11b. At this time, the first pulley 13 and the second pulley 14 are respectively arranged in the first step 11a and the second step 11b, which can improve the compactness of the distribution between the first pulley 13 and the second pulley 14 and the sliding carrier 11, thereby facilitating further reducing the overall volume of the linear slide 10. Of course, it should be noted that the present application is not limited to this. In other embodiments, the pulley 13 on the first mounting portion 111 can also be located on the side of the first mounting portion 111 away from the first step 11a, and the pulley 13 on the second mounting portion 116 can also be located on the side of the second mounting portion 116 away from the second step 11b.

[0069] In one embodiment of the present application, the first plate 113, the second plate 114, the third plate 115, the first mounting portion 111 and the second mounting portion 116 are an integrated structure. In this way, the overall strength of the sliding carrier 11 is high, which is conducive to improving the service life of the sliding carrier 11 and the stability of the load-bearing of the pulley 13 and the objects to be moved. Moreover, the sliding carrier 11 with an integrated structure can also facilitate the elastic portion 112 to form a strong deformation elastic force, and it is not easy to cause breakage and separation after elastic deformation. In addition, the sliding carrier 11 can be manufactured by integral molding, so that there is no need to additionally connect and assemble the first plate 113, the second plate 114, the third plate 115, the first mounting portion 111 and the second mounting portion 116, which is conducive to improving the convenience and efficiency of manufacturing the sliding carrier 11. Of course, in other embodiments, the first plate 113, the second plate 114, the third plate 115, the first mounting portion 111 and the second mounting portion 116 are arranged separately, and then assembled and fixed by any connection method such as welding.

[0070] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the first mounting portion 111 and the second mounting portion 116 are both plate structures. In this way, the first mounting portion 111 and the second mounting portion 116 are relatively corresponding to the elastic portion 112 which is also a plate structure, which can facilitate the connection between the first mounting portion 111 and the first plate 113, and the connection between the second mounting portion 116 and the third plate 115, thereby facilitating the manufacturing convenience of the sliding carrier 11. Moreover, the volume of the first mounting portion 111 and the second mounting portion 116 can be relatively small, which can reduce raw materials and help reduce manufacturing costs. At the same time, the first mounting portion 111 and the second mounting portion 116 can have better rigidity.

[0071] Please refer to Figures 1 to 3 In one embodiment of the present application, the number of the first pulleys 13 is at least two (for example, two, three, four or more), and the two first pulleys 13 are arranged side by side along the second direction on the first mounting portion 111, and the second direction, the first direction and the extension direction of the rotation axis of the first pulley 13 intersect each other.

[0072] In this embodiment, at least two first pulleys 13 are arranged side by side along the second direction, so that the linear slide 10 and the track 30 are more in contact with each other, and the contact position between the linear slide 10 and the track 30 is increased, so that the two can be clamped more stably, which is conducive to improving the stability of the linear slide 10 during the movement on the track 30. The second direction can be perpendicular to the first direction; when the first direction is the up-down direction, the second direction can be the left-right direction.

[0073] Please refer to Figure 3In one embodiment of the present application, the first mounting portion 111 is provided with a first partition portion (not shown) between two adjacent first pulleys 13, and the first partition portion divides the first mounting portion 111 in the second direction to form at least two first sub-mounting portions (not shown), and each first sub-mounting portion is provided with at least one first pulley 13.

[0074] In this embodiment, a first partition is provided between two adjacent first pulleys 13 on the first mounting portion 111, so that when the linear slide 10 is installed on the track 30, when a certain first pulley 13 deviates from the track 30 in the direction of the rotation axis, the installation posture of the first pulley 13 can be adjusted by only driving the first sub-mounting portion corresponding to the first pulley 13 to undergo elastic deformation. Therefore, the provision of the first partition (not shown) can play a force-isolating role for the first pulley 13, so that at least two first pulleys 13 have different pre-compression deformation amounts on the first mounting portion 111, thereby improving the problem of non-parallelism of at least two first pulleys 13 caused by processing and / or assembly errors, so that the linear slide 10 and the track 30 have a higher fault tolerance rate during assembly. Among them, the first partition can be in the form of a first partition groove (not shown), and of course it can also be in the form of a partition slit or a partition hole. In addition, the number of first partitions can be one, and of course it can also be two or more, and the present application does not limit the number of first partitions. In addition, when the first mounting portion 111 is a plate structure, the first sub-mounting portion may be a sub-plate, that is, the structural type of the first sub-mounting portion may be determined by the structural type of the first mounting portion 111 .

[0075] Please refer to Figure 3 In one embodiment of the present application, the first dividing groove passes through both sides of the first mounting portion 111 in the direction of the rotation axis of the first pulley 13, and the first dividing groove passes through at least a portion of the first mounting portion 111 along the first direction from one end of the first mounting portion 111 away from the elastic portion 112.

[0076] In this embodiment, the first partition is set as a first partition groove, so that there is a spacing between the two first sub-mounting parts separated by the first partition groove. At this time, when the first sub-mounting part is elastically deformed in the direction of the rotation axis of the first pulley 13, it can have a larger deformation space, which is conducive to increasing the elastic deformation capacity of the first sub-mounting part, and further improving the fault tolerance of the linear slide 10 when assembling on the track 30.

[0077] In one embodiment of the present application, the first partition extends along the first direction and partitions at least a portion of the elastic portion 112. For example, the first partition partitions a portion of the elastic portion 112 or partitions all of the elastic portion 112.

[0078] In this embodiment, the first partition is extended to at least part of the partitioning elastic portion 112, so that the first sub-mounting portions located on opposite sides of the first partition can be fully separated, which is conducive to improving the separation effect of the first partition on the first mounting portion 111, so that when a certain first sub-mounting portion is driven to deform along the rotation axis direction of the first pulley 13, the driving effect on the adjacent first sub-mounting portion can be reduced. On the other hand, because the elastic portion 112 is separated, when a certain first sub-mounting portion is driven to deform in the first direction through the elastic portion 112, the driving effect on the adjacent first sub-mounting portion can also be reduced. Therefore, at this time, when adjusting the installation posture of the first pulley 13 on each first sub-mounting portion, whether in the rotation axis direction of the first pulley 13 or in the first direction, due to the separation effect of the first partition, the deformation adjustment of the two adjacent first sub-mounting portions will not affect each other, which is conducive to improving the adjustment effect of the installation posture of the first pulley 13 on each first sub-mounting portion. Among them, when the elastic part 112 includes the above-mentioned first plate body 113, the second plate body 114 and the third plate body 115, the first partition can extend to the part that separates the second plate body 114. Further, in order to improve the uniformity of the partition effect of the first partition, in the second direction, the first partition can correspond to the middle position of the elastic part 112, so that the first sub-mounting parts located on the opposite sides of the first partition can have a relatively uniform force arm, and then can all be more portable and elastically deformed. In particular, when the center line of the elastic part 112 in the second direction coincides with the center line between the two adjacent first pulleys 13, the uniformity of the deformation elastic force between each first sub-mounting part can be improved. In addition, in some embodiments, in the second direction, the size of the elastic part 112 can be smaller than the size of the first mounting part 111 and the second mounting part 116 to further enhance the elastic deformation ability of the elastic part 112. At this time, in order to improve the convenience of manufacturing, the elastic part 112 and the first partition can be close to one end of the first mounting part 111 and the second mounting part 116 in the second direction.

[0079] Please refer to Figures 1 to 3 In one embodiment of the present application, the number of the second pulleys 14 is at least two (eg, two, three, four or more), and at least two second pulleys 14 are arranged side by side on the second mounting portion 116 along the second direction.

[0080] In this embodiment, at least two second pulleys 14 are arranged side by side along the second direction, so that the linear slide 10 can be abutted against the track 30 through the two second pulleys 14, increasing the contact position between the linear slide 10 and the track 30, so that the two can be clamped more stably, which is beneficial to improve the anti-shake ability of the linear slide 10 and further improve the stability of the linear slide 10 during movement on the track 30.

[0081] Please refer to Figure 3 In one embodiment of the present application, the second mounting portion 116 is provided with a second partition portion 117 between two adjacent second pulleys 14 , and the second partition portion 117 separates the second mounting portion 116 in the second direction to form at least two second sub-mounting portions 123 , and each second sub-mounting portion 123 is provided with at least one second pulley 14 .

[0082] In this embodiment, a second partition 117 is provided between two adjacent second pulleys 14 on the second mounting portion 116, so that when the linear slide 10 is installed on the track 30, when a second pulley 14 deviates from the track 30 in the direction of the rotation axis, the installation posture of the second pulley 14 can be adjusted by only driving the second sub-mounting portion 123 corresponding to the second pulley 14 to undergo elastic deformation. Therefore, the provision of the second partition 117 can play a force isolation role for the second pulley 14, so that at least two second pulleys 14 can have different pre-compression deformation amounts on the second mounting portion 116, thereby improving the problem of non-parallelism of at least two second pulleys 14 caused by processing and / or assembly errors, so that the linear slide 10 and the track 30 have a higher fault tolerance rate during assembly. Among them, the second partition 117 can be in the structural form of a second partition groove 118, and of course, it can also be in the structural form of a partition slit or a partition hole. In addition, the number of the second partitions 117 can be one, or two or more, and the present application does not limit the number of the second partitions 117. In addition, when the second mounting portion 116 is a plate structure, the second sub-mounting portion 123 can be a sub-plate. That is, the structural type of the second sub-mounting portion 123 can be determined by the structural type of the second mounting portion 116.

[0083] Please refer to Figure 3 In one embodiment of the present application, the second dividing portion 117 is a second dividing groove 118, and the second dividing groove 118 passes through both sides of the second mounting portion 116 in the direction of the rotation axis of the second pulley 14, and the second dividing groove 118 passes through at least a portion of the second mounting portion 116 along the first direction from one end of the second mounting portion 116 away from the elastic portion 112.

[0084] In this embodiment, the second partition 117 is set as the second partition groove 118, so that there is a spacing between the two second sub-mounting portions 123 separated by the second partition groove 118. At this time, when the second sub-mounting portion 123 undergoes elastic deformation, it can have a larger deformation space, which is conducive to increasing the elastic deformation capacity of the second sub-mounting portion 123, and further improving the fault tolerance rate when the linear slide 10 is assembled on the track 30.

[0085] Please refer to Figure 3 In one embodiment of the present application, the groove wall of the second dividing groove 118 includes a first groove wall 119 and a third groove wall 121, a second groove wall 120, and the second groove wall 120 and the first groove wall 119 are arranged opposite to each other in the second direction; the opposite ends of the third groove wall 121 are respectively connected to the first groove wall 119 and the second groove wall 120, and the third groove wall 121 is arranged in a concave arc surface.

[0086] In this embodiment, the third groove wall 121 in the second dividing groove 118 is set to an arc surface, so that no corners are formed between the first groove wall 119 and the third groove wall 121, and between the second groove wall 120 and the third groove wall 121 to cause stress concentration and damage, which is beneficial to improve the service life of the sliding carrier 11. Among them, the first groove wall 119 and the second groove wall 120 can be planes, and the distance between the two can be the diameter of the third groove wall 121, so that the shape of the dividing groove 118 is more regular, which is beneficial to improve the convenience of its processing. In addition, in one embodiment, the structure and shape of the first dividing groove described above can be the same as the structure and shape of the second dividing groove 118.

[0087] Please refer to Figure 1 and Figure 3 In one embodiment of the present application, the second partition portion 117 extends in the first direction and partitions at least a portion of the elastic portion 112 .

[0088] In this embodiment, the second partition 117 is extended to at least a portion of the partitioning elastic portion 112, so that the second sub-mounting portions 123 located on opposite sides of the second partition 117 can be fully separated, which is conducive to improving the separation effect of the second partition 117 on the second mounting portion 116, so that when a second sub-mounting portion 123 is driven to deform along the second pulley 14, the driving effect on the adjacent second sub-mounting portion 123 can be reduced. On the other hand, because the elastic portion 112 is separated, when a second sub-mounting portion 123 is driven to deform in the first direction through the elastic portion 112, the driving effect on the adjacent second sub-mounting portion 123 can also be reduced. Therefore, when adjusting the installation posture of the second pulley 14 on each second sub-mounting portion 123, whether in the direction of the rotation axis of the second pulley 14 or in the first direction, due to the separation effect of the second partition 117, the deformation adjustment of the two adjacent second sub-mounting portions 123 will not affect each other, which is conducive to improving the adjustment effect of the installation posture of the second pulley 14 on each second sub-mounting portion 123. Wherein, when the elastic portion 112 includes the above-mentioned first plate body 113, second plate body 114 and third plate body 115, the second partition 117 can extend to the part that separates the second plate body 114. Further, in order to improve the uniformity of the separation effect of the second partition 117, in the second direction, the partition 117 can be located in the middle position of the elastic portion 112, so that the second sub-mounting portions 123 located on the opposite sides of the partition 117 can have a relatively uniform force arm, and can then be more portable and elastically deformed. In particular, when the center line of the elastic portion 112 in the second direction coincides with the center line between two adjacent second pulleys 14, the uniformity of the deformation elastic force between each second sub-mounting portion 123 can be improved. In addition, in some embodiments, in the second direction, the size of the elastic portion 112 can be smaller than the size of the first mounting portion 111 and the second mounting portion 116 to further enhance the elastic deformation capacity of the elastic portion 112. At this time, in order to improve the convenience of manufacturing, the elastic portion 112 and the second partition portion 117 can be close to one end of the first mounting portion 111 and the second mounting portion 116 in the second direction.

[0089] Please refer to Figure 3 In one embodiment of the present application, two first pulleys 13 are provided on the first mounting portion 111 , two second pulleys 14 are provided on the second mounting portion 116 , and a second partition portion 117 is provided between two adjacent second pulleys 14 on the second mounting portion 116 .

[0090] In this embodiment, two first pulleys 13 are arranged on the first mounting portion 111, so that when the linear slide 10 is mounted on the track 30, the connection line formed by connecting the two first pulleys 13 can be adjusted to correspond to the extension direction of the track 30 more conveniently. That is, the two first pulleys 13 on the first mounting portion 111 can be used as a reference to directly abut on the abutting surface on one side of the track 30, and then the second sub-mounting portion 123 separated by the second partition 117 in the second mounting portion 116 can be driven to adjust the installation posture of the second pulleys 14 installed on each second sub-mounting portion 123 to accurately abut on the abutting surface on the other side of the track 30. At this time, on the one hand, the installation posture of each second pulley 14 can be adjusted only on the side where the second mounting portion 116 is located, which is conducive to improving the convenience of installing the linear slide 10. On the other hand, the structure of the linear slide 10 can also be simplified, which is conducive to improving the convenience of manufacturing the linear slide 10.

[0091] Please refer to Figure 3 In one embodiment of the present application, there are at least two first pulleys 13 and the same number of second pulleys 14, and the at least two first pulleys 13 and the at least two second pulleys 14 correspond one to one in the first direction.

[0092] In this embodiment, the number of the first pulley 13 and the second pulley 14 is set to be the same, and they are also set one by one, so that the first pulley 13 and the second pulley 14 on both sides of the linear slide 10 can be arranged more regularly, which is conducive to improving the convenience of its manufacture and the compactness of the structure. At the same time, the linear slide 10 can be uniformly stressed by the first pulley 13 and the second pulley 14 on both sides, which is conducive to further improving the stability of the linear slide 10 as a whole on the track 30. In one embodiment, the number of the first pulley 13 and the second pulley 14 is two, so that the number of the first pulley 13 and the second pulley 14 will not be too small, which is conducive to improving the stability of the clamping between the linear slide 10 and the track 30. On the other hand, the number of the first pulley 13 and the second pulley 14 will not be too large, so that the structure of the linear slide 10 will not be too complicated, which is conducive to improving the convenience of its manufacture and reducing the manufacturing cost. Therefore, setting the number of the first pulley 13 and the second pulley 14 to two can better take into account the stability of the clamping of the linear slide 10 and the simplification of the structure.

[0093] Please refer to Figure 4The present application also proposes a guide rail mechanism 100, which includes a track 30 and a linear slide 10. The specific structure of the linear slide 10 refers to the above embodiment. Since the guide rail mechanism 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0094] The pulley 13 in the linear slide 10 is installed on the track 30. Specifically, the track 30 may include two optical axes 31, and the first pulley 13 and the second pulley 14 on both sides of the first direction of the linear slide 10 may be respectively abutted between the two optical axes 31 to achieve the clamping of the linear slide 10 on the track 30. In order to further improve the stability of the linear slide 10 sliding on the track 30, the side circumference of the first pulley 13 may be recessed to form a first limiting groove 131, and the side circumference of the second pulley 14 may also be recessed to form a second limiting groove 141. The optical axis 31 may be a round rod-shaped structure, and parts of the two optical axes 31 are respectively adapted to be accommodated in the first limiting groove 131 and the second limiting groove 141. At this time, the wall surface where the optical axis 31 abuts against the groove wall of the first limiting groove 131 and the second limiting groove 141 is the abutting surface mentioned above.

[0095] The present application also proposes a linear drive device (not shown), which includes a drive member and a guide rail mechanism 100. The specific structure of the guide rail mechanism 100 refers to the above embodiment. Since the present linear drive device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the drive member can be used to drive the linear slide 10 in the guide rail mechanism 100 to slide along the track 30. In order to allow the linear slide 10 to have a relatively large sliding stroke, the drive member can be a motor or a rotary cylinder, etc. At this time, the linear drive device can further include a transmission structure (such as a pulley and a belt) so that the drive member drives the linear slide 10 connected to the transmission structure to slide through the transmission structure.

[0096] The present application also proposes a laser processing device, which includes a linear drive device. The specific structure of the linear drive device refers to the above embodiment. Since the laser processing device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the laser processing equipment can also include a laser head, which can be installed on the linear drive device, specifically on the linear slide 10, so as to drive the laser head to move through the linear drive device, thereby realizing the processing of different parts of the workpiece, that is, the laser head is the object to be driven. Further, the laser processing equipment can include one, two or more linear drive devices. At this time, the laser processing equipment can have two perpendicular X-axis directions, Y-axis directions and Z-axis directions, the X-axis direction and the Y-axis direction can be two horizontal directions (left-right direction and front-back direction), and the Z-axis direction can be the up-down direction. Since the laser head has a large stroke in the horizontal direction, the two linear drive devices are respectively the first linear drive device and the second linear drive device. The linear slide 10 of the first linear drive device slides along the X-axis direction, and the second linear drive device can be connected to the linear slide 10 in the first drive device, and the linear slide 10 in the second linear drive device can slide along the Y-axis direction, and the laser head can be installed on the linear slide 10 in the second linear drive device, thereby realizing the movement of the laser head in the X-axis direction and the Y-axis direction. Of course, in order to enable the laser head to further move in the Z-axis direction, the laser processing equipment may include three linear drive devices, so that on the basis of including the aforementioned first linear drive device and the second linear drive device, a third linear drive device may also be included. At this time, the third linear drive device can be connected to the linear slide 10 in the second linear drive device, and the linear slide 10 in the third drive device can slide along the Z-axis direction, and the laser head can be installed on the linear slide 10 in the third linear drive device. Of course, in other embodiments, the third linear drive device can also be replaced by a combination of a motor and a screw as a power mechanism for the laser head in the Z-axis direction.
