DETAILED DESCRIPTION

[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0041] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of the present invention.

[0042] like Figures 1 to 3 As shown, the present invention provides a grating ruler installation device. Among them, one side of the grating ruler 200 forms a fitting surface that fits with the equipment, and an attachment layer 201 is pre-attached on the fitting surface, and the attachment layer 201 can specifically be a release paper. In some existing equipment, it is necessary to attach the grating ruler 200 to the surface of the guide rail 300 in the equipment. The grating ruler installation device of the present application is used to assist the attachment operation of the grating ruler 200 to the surface of the guide rail 300. The grating ruler installation device of the present application includes a reference plate 1, a separation component 2 and a clamping member 3, and may also include a sliding component 4 and a supporting plate 5.

[0043] Reference Figure 1 , the reference plate 1 is used to fit with the guide rail 300 and can slide relative to the guide rail 300. Specifically, the shape of the reference plate 1 is adapted to the shape of the guide rail 300, so that the reference plate 1 can fit closely with the guide rail 300. The reference plate 1 can slide relative to the guide rail 300 along the attachment direction of the grating scale 200, and when the reference plate 1 slides relative to the guide rail 300, the reference plate 1 can be kept in contact with the guide rail 300, thereby ensuring that the relative position between the reference plate 1 and the guide rail 300 remains substantially unchanged. Among them, the attachment direction of the grating scale 200 is the same as the extension direction of the guide rail 300.

[0044] In this embodiment, the guide rail 300 includes adjacent first and second surfaces 301 and 302. The first surface 301 of the guide rail 300 is used to attach the grating scale 200, and the first surface 301 may be the side of the guide rail 300, and the second surface 302 may be the upper surface of the guide rail 300. The reference plate 1 may specifically include a first plate body 11 and a second plate body 12 connected to each other. The first plate body 11 of the reference plate 1 is parallel to the first surface 301 of the guide rail 300, and the first plate body 11 is used to fit the first surface 301 of the guide rail 300; the second plate body 12 of the reference plate 1 is parallel to the second surface 302 of the guide rail 300, and the second plate body 12 is used to fit the second surface 302 of the guide rail 300. The upper end of the first plate body 11 may specifically be integrally connected to the second plate body 12, and the first plate body 11 may be a vertical plate body, and the second plate body 12 may be a horizontal plate body, and the reference plate 1 constitutes an "L-shaped plate".

[0045] When the reference plate 1 is attached to the guide rail 300, the reference plate 1 can be attached to a corner of the guide rail 300 to complete the adhesion of the reference plate 1 and the guide rail 300, and the second plate body 12 can limit the movement of the reference plate 1 relative to the guide rail 300 along the height direction of the guide rail 300 after being adhered to the second surface 302 of the guide rail 300, so that after the reference plate 1 is attached to the guide rail 300, the relative position of the reference plate 1 and the guide rail 300 along the height direction of the guide rail 300 remains basically unchanged. Therefore, the grating scale installation device of the present application does not need to pre-process the installation reference. When the reference plate 1 is attached to the guide rail 300, the reference plate 1 can be used as the installation reference, and other components in the grating scale installation device can be installed on the reference plate 1. Since the reference plate 1 remains basically unchanged relative to the guide rail 300 along the height direction of the guide rail 300, the other components installed on the reference plate 1 can keep their positions fixed with the reference plate 1 and remain basically unchanged relative to the guide rail 300 along the height direction of the guide rail 300, thereby ensuring the position accuracy of other components installed on the reference plate 1 in the grating scale installation device. Furthermore, when the reference plate 1 slides relative to the guide rail 300, the second plate body 12 of the reference plate 1 remains in contact with the second surface 302 of the guide rail 300, and limits the movement of the reference plate 1 along the height direction of the guide rail 300 during the sliding process. As a result, the position of the reference plate 1 and the components mounted on the reference plate 1 along the height direction of the guide rail 300 remains basically unchanged during the sliding process. There is no need to perform multiple measurements when the grating scale installation device moves relative to the guide rail 300, which simplifies the operating steps of the grating scale installation device and the installation steps of the grating scale 200, thereby improving the installation efficiency of the grating scale 200.

[0046] Reference Figure 2In order to facilitate the sliding of the reference plate 1 relative to the guide rail 300, the reference plate 1 can be connected to the sliding assembly 4. The sliding assembly 4 includes a limiting member 41, and can also include a first rod body 42 and a second rod body 43. The limiting member 41 and the first plate body 11 are distributed at opposite ends of the guide rail 300, and the spacing between the limiting member 41 and the first plate body 11 is adapted to the width of the guide rail 300, that is, the same or substantially the same as the width of the guide rail 300. For example, when the limiting member 41 is installed, the limiting member 41 fits the guide rail 300 or there is no obvious gap between the limiting member 41 and the guide rail 300 when observed with the naked eye. Therefore, the limiting member 41 and the first plate body 11 can be clamped on the guide rail 300, thereby limiting the movement of the first plate body 11 of the reference plate 1 relative to the guide rail 300 along the width direction of the guide rail 300, that is, the positions of the reference plate 1 and the guide rail 300 along the width direction of the guide rail 300 can be kept basically unchanged, thereby ensuring that the positions of the reference plate 1 and the components installed on the reference plate 1 and the guide rail 300 along the width direction of the guide rail 300 remain basically unchanged. Ensure the positional accuracy between the reference plate 1 and the components installed on the reference plate 1 and the guide rail 300. Among them, the limiting member 41 can be specifically a roller. When the reference plate 1 slides relative to the guide rail 300, the limiting member 41 will also move with the reference plate 1 and then slide synchronously relative to the guide rail 300. Setting the limiting member 41 as a roller can reduce the friction force when the limiting member 41 slides relative to the guide rail 300, thereby making the sliding of the reference plate 1 and the limiting member 41 relative to the guide rail 300 smoother.

[0047] One end of the first rod 42 is connected to the reference plate 1, specifically, to the second plate 12 of the reference plate 1, and the other end of the first rod 42 is connected to the second rod 43. The second rod 43 can be connected to the limiting member 41, so that the limiting member 41 can be indirectly connected to the reference plate 1 through the second rod 43 and the first rod 42, and can move synchronously with the reference plate 1. The first rod 42 can be parallel to the second plate 12, and the first rod 42 can be located above the guide rail 300; the second rod 43 can be parallel to the first plate 11 and arranged opposite to the first plate 11, that is, the second rod 43 and the first plate 11 can be located on opposite sides of the guide rail 300.

[0048] Reference Figure 2 and Figure 4In order to facilitate the adjustment of the spacing between the limiting member 41 and the first plate body 11, the sliding assembly 4 further includes an adjusting member 44. The first rod body 42 is provided with a groove body 421 extending along the width direction of the guide rail 300; the second plate body 12 is provided with a matching hole 121 connected to the groove body 421, and the matching hole 121 can be adapted to the adjusting member 44 and keep the adjusting member 44 fixed. For example, when the matching hole 121 is a blind hole or a through hole, the matching hole 121 can be interference-fitted with the adjusting member 44; when the matching hole 121 is a threaded hole, the matching hole 121 can be threadedly matched with the adjusting member 44. When it is necessary to keep the first rod body 42 and the second plate body 12 fixed, the adjusting member 44 can pass through the groove body 421 and match with the matching hole 121, so that the adjusting member 44 presses and fixes the first rod body 42 to the second plate body 12. When it is necessary to adjust the distance between the limiting member 41 and the first plate body 11, the matching relationship between the adjusting member 44 and the matching hole 121 can be released, and then the position of the first rod body 42 can be changed along the extension direction of the groove body 421 to adjust the distance between the limiting member 41 and the first plate body 11, and make different positions of the groove body 421 located above the matching hole 121. When the distance adjustment between the limiting member 41 and the first plate body 11 is completed, the adjusting member 44 passes through the groove body 421 and matches with the matching hole 121, so that the adjusting member 44 presses and fixes the first rod body 42 to the second plate body 12.

[0049] Reference Figures 5 to 8 , the separation component 2 is used to assist in separating the grating scale 200 and the attachment layer 201, and the separated grating scale 200 can be attached to the first surface 301 of the guide rail 300. The separation component 2 can be installed on the reference plate 1, and specifically can be installed on the first plate body 11 of the reference plate 1. The separation component 2 can be fixedly installed on the first plate body 11 by fasteners such as screws. When the separation component 2 is fixedly installed on the first plate body 11, the separation component 2 can be kept fixed relative to the reference plate 1 along the height direction and the width direction of the guide rail 300, and the relative position of the separation component 2 and the guide rail 300 along the height direction and the width direction of the guide rail 300 can remain basically unchanged, thereby making the relative position of the grating scale 200 obtained after the separation of the separation component 2 and the guide rail 300 along the height direction and the width direction of the guide rail 300 basically unchanged, so as to ensure the position accuracy of the separated grating scale 200 relative to the guide rail 300.

[0050] By adjusting the position of the separation component 2 mounted on the first plate 11, the position of the separation component 2 relative to the guide rail 300 along the height direction of the guide rail 300 can be adjusted, and then the position of the grating scale 200 separated by the separation component 2 relative to the guide rail 300 along the height direction of the guide rail 300 can be adjusted, so that the separated grating scale 200 can be located at the required installation height of the guide rail 300. Afterwards, by sliding the reference plate 1 relative to the guide rail 300, the separated grating scale 200 can be moved along the extension direction of the guide rail 300 at the required installation height, and then the attachment operation of the grating scale 200 on the guide rail 300 can be realized.

[0051] The separation component 2 is formed with a separation space 21 and a separation groove 22 connected to the separation space 21. The separation space 21 can be used for separation of the grating scale 200 and the attachment layer 201. The separated grating scale 200 extends toward the separation groove 22, and the separated attachment layer 201 can extend away from the separation groove 22. One end of the separation groove 22 is connected to the separation space 21, and the other end can pass through the separation component 2 and communicate with the outside world, and the separation groove 22 can allow the separated grating scale 200 to pass through the separation groove 22 and pass out of the separation component 2. Among them, the height of the separation groove 22 can be adapted to the width of the grating scale 200, for example, the height of the separation groove 22 is equal to or slightly larger than the width of the grating scale 200, and specifically, the height of the separation groove 22 can be 0 to 0.1 mm more than the width of the grating scale 200.

[0052] Reference Figure 8 Specifically, the separation assembly 2 may include a first separation block 23 and a second separation block 24 that are arranged opposite to each other. The first separation block 23 includes a first body portion 231 and a first protrusion 232 that protrudes from the first body portion 231 toward the second separation block 24. The second separation block 24 includes a second body portion 241 and a second protrusion 242 that protrudes from the second body portion 241 toward the first separation block 23. The first protrusion 232 may be formed by protruding from a portion of the surface of the first body portion 231, and the second protrusion 242 may be formed by protruding from a portion of the surface of the second body portion 241, and the projections of the first protrusion 232 and the second protrusion 242 along the height direction of the guide rail 300 do not overlap and are spaced from each other, so that the first protrusion 232 and the second protrusion 242 can be arranged in a staggered interval.

[0053] The thickness of the first protrusion 232 and the second protrusion 242 can be the same or substantially the same. When the first separation block 23 and the second separation block 24 are arranged relative to each other, the first protrusion 232 can abut against the second body part 241, the second protrusion 242 can abut against the first body part 231, and the first protrusion 232 and the second protrusion 242 are spaced from each other. At this time, the surface of the first body part 231 facing the second body part 241, the surface of the second body part 241 facing the first body part 231, the side wall of the first protrusion 232, and the side wall of the second protrusion 242 together enclose a continuous space, which includes a narrow channel and a wide area. The narrow channel forms the separation groove 22, and the wide area forms the separation space 21.

[0054] By adopting a method in which the first separation block 23 and the second separation block 24 are arranged relative to each other to form the separation space 21 and the separation groove 22, the assembly method of the first separation block 23 and the second separation block 24 can be simplified. Only two components need to be stacked up and down, and then fixedly connected by fasteners such as screws to complete the assembly of the first separation block 23 and the second separation block 24; and the first separation block 23 and the second separation block 24 have a simple structure and can be easily processed.

[0055] Reference Figure 5 and Figure 7 In order to facilitate the separation of the grating scale 200 and the attachment layer 201 in the separation space 21, the separation component 2 may also be provided with a separation column 25, at least a portion of which is provided in the separation space 21. The separation point of the grating scale 200 and the attachment layer 201 may be adjacent to the separation column 25, and the separated grating scale 200 extends toward the separation groove 22, and the separated attachment layer 201 is attached to the separation column 25, and changes the extension direction around the separation column 25 so that the separated attachment layer 201 can extend away from the separation groove 22. At this time, the separated grating scale 200 and the attachment layer 201 can extend in two opposite directions without interfering with each other, and the attachment of the separated grating scale 200 and the recovery of the separated attachment layer 201 can be facilitated.

[0056] In order to prevent the separation column 25 from interfering with the operation of the grating scale 200 and the attachment layer 201 at the beginning of separation, the separation column 25 can be set as a retractable structure. Specifically, one end of the separation column 25 extends into the separation space 21 and forms a separation end 252, and the separation end 252 is used to fit with the attached layer 201 after separation so that the attached layer 201 can change the extension direction around the separation end 252; the other end of the separation column 25 can be exposed to the outside and form a driving end 251. By applying a force to the driving end 251 manually or by using a driving device such as a motor or a cylinder, the separation column 25 can be driven to move, and then the separation end 252 of the separation column 25 can be moved out of or into the separation space 21. Refer to Figure 6When the grating ruler 200 and the attachment layer 201 begin to separate, a force is applied to the driving end 251 so that the separation end 252 of the separation column 25 moves out of the separation space 21, and then the grating ruler 200 and the attachment layer 201 begin to separate; refer to Figure 5 After the grating ruler 200 is separated from the attachment layer 201, the separation end 252 of the separation column 25 can be moved into the separation space 21, and the separated attachment layer 201 changes its extension direction around the separation end 252. The separation column 25 can also be connected to a spring, and when the separation end 252 of the separation column 25 moves out of the separation space 21, the spring is squeezed. When the separation end 252 of the separation column 25 needs to move into the separation space 21, the separation end 252 of the separation column 25 can be driven by the elastic force of the spring to reset to the separation space 21.

[0057] In order to ensure that the separation column 25 can remain fixed relative to the separation component 2 when the separation end 252 is moved out of or into the separation space 21, the separation component 2 includes a limiting sleeve 26 sleeved on the separation column 25. The limiting sleeve 26 can remain fixed with the separation component 2, for example, the limiting sleeve 26 can be interference-fitted with the second body portion 241 in the separation component 2; the limiting sleeve 26 can also be provided with a limiting card slot 261, and the separation column 25 is provided with a limiting card block 253 that cooperates with the limiting card slot 261. The limiting card block 253 is a protrusion formed by protruding from the side of the separation column 25 along the radial direction of the separation column 25. Figure 5 When the separation end 252 of the separation column 25 is located in the separation space 21, the limiting block 253 is located in the limiting slot 261, and the limiting block 253 abuts against the bottom wall forming the limiting slot 261 to limit the movement of the separation column 25 and the limiting sleeve 26 along the axial direction of the separation column 25, thereby keeping the separation column 25 fixed relative to the separation assembly 2; Figure 6 When the separation column 25 moves out of the separation space 21, the limiting block 253 of the separation column 25 can move out of the limiting slot 261. At this time, the separation column 25 is rotated so that the limiting block 253 of the separation column 25 is misaligned with the limiting slot 261, and the limiting block 253 can abut against the bottom wall of the limiting sleeve 26 to limit the movement of the separation column 25 and the limiting sleeve 26 along the axial direction of the separation column 25, thereby keeping the separation column 25 fixed relative to the separation assembly 2. When it is necessary to move the separation end 252 of the separation column 25 into the separation space 21, the separation column 25 is rotated so that the limiting block 253 of the separation column 25 is opposite to the limiting slot 261 of the limiting sleeve 26. At this time, the limiting block 253 can move along the axial direction of the separation column 25 into the limiting slot 261 and keep the separation end 252 of the separation column 25 in the separation space 21.

[0058] Reference Figure 3, the pressing member 3 is movably mounted on the reference plate 1 or the separation assembly 2. The pressing member 3 is arranged on the side of the separation groove 22 away from the separation space 21, so that the pressing member 3 and the grating ruler 200 after separation and passing through the separation groove 22 are located on the same side of the separation assembly 2. At this time, the pressing member 3 can be pressed on the grating ruler 200 passing through the separation groove 22 to press the grating ruler 200 and attach it to the surface of the guide rail 300. In order to reduce the damage to the grating ruler 200 caused by the pressing member 3 when pressing the grating ruler 200, the pressing member 3 is a rubber roller. The rubber roller made of flexible material can reduce the damage to the grating ruler 200 caused by the pressing member 3 when pressing the grating ruler 200, and the rubber roller can roll when moving relative to the grating ruler 200, thereby reducing the friction between the pressing member 3 and the grating ruler 200, and further reducing the damage to the grating ruler 200 caused by the pressing member 3 when pressing the grating ruler 200.

[0059] Specifically, the pressing member 3 can be movably mounted on the separation assembly 2. The pressing member 3 is connected to a swing rod 31, one end of the swing rod 31 is rotatably connected to the separation assembly 2, for example, pivotally connected to the first separation block 23 of the separation assembly 2, and the other end of the swing rod 31 is fixedly connected to the pressing member 3. The swing rod 31 rotates relative to the separation assembly 2 in a direction toward or away from the guide rail 300, so that the pressing member 3 connected to the swing rod 31 can move toward or away from the guide rail 300. When the grating scale 200 is just beginning to be attached to the guide rail 300, the pressing member 3 can be driven away from the guide rail 300, thereby facilitating the grating scale 200 to be attached to the guide rail 300. After the grating scale 200 is attached to the guide rail 300, the pressing member 3 is driven to be pressed against the grating scale 200. In other embodiments, the pressing member 3 can also be rotatably connected to the first plate body 11 of the reference plate 1 through the swing rod 31, which is not limited here.

[0060] When the reference plate 1 slides along the guide rail 300, the attachment layer 201 can be pulled manually or by a driving device such as a motor or a cylinder, so that the length of the separated grating ruler 200 gradually increases with the movement of the reference plate 1. At the same time, the pressing member 3 installed on the separation component 2 will move synchronously with the reference plate 1, so that the pressing member 3 gradually presses the grating ruler 200 along the extension direction of the guide rail 300, and the grating ruler 200 gradually adheres to the guide rail 300 along the extension direction of the guide rail 300. The pressing force applied by the pressing member 3 to the grating ruler 200 can be applied manually. In addition, the pressing force applied by the pressing member 3 to the grating ruler 200 can also be applied by the elastic force of the elastic member or the driving force of a driving device such as a cylinder.

[0061] Reference Fig. 9In order to facilitate the installation of the grating ruler 200 and the attachment layer 201, the reference plate 1 can be connected to a bearing plate 5. Specifically, the bearing plate 5 is fixedly mounted on the reference plate 1, and the bearing plate 5 can be used to carry the grating ruler 200 and / or the attachment layer 201. For example, the bearing plate 5 is provided with an inner ring 51 and an outer ring 52, and a containing space is formed between the inner ring 51 and the outer ring 52. The inner ring 51 can be a closed ring, and the outer ring 52 can be a gap ring with a gap. The unseparated grating ruler 200 and the attachment layer 201 can be wrapped around the inner ring 51 and located in the containing space. When it is necessary to separate the grating ruler 200 and the attachment layer 201, the grating ruler 200 and the attachment layer 201 can extend through the gap of the outer ring 52 to the separation component 2 for separation. Among them, in order to avoid the grating ruler 200 and the attachment layer 201 from being scratched and damaged by the outer ring 52 at the gap of the outer ring 52, the gap of the outer ring 52 is processed with an arc transition.
