Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a processing equipment. Background Technology

[0002] In related technologies, processing equipment often uses a worktable that is driven and raised by a lead screw assembly to facilitate the processing of workpieces of varying heights. However, due to factors such as processing and installation errors, the alignment of the fixed position at the end of the lead screw assembly with the mounting hole on the worktable through which the lead screw assembly passes can easily deviate. This results in uneven stress on the lead screw assembly due to the radial pressure exerted by the worktable, causing the drive of the worktable to become jerky. Utility Model Content

[0008] An adjustment structure is provided between the stage and the lead screw nut to allow the lead screw nut to move relative to the stage in a direction intersecting the axis of the lead screw; and

[0014] Optionally, the groove is a T-groove or a dovetail groove, and the shape of the slider is adapted to the shape of the groove.

[0015] Optionally, the direction parallel to the lead screw axis is defined as the first direction, and the adjustment structure includes a first connector, a second connector, and a third connector, wherein the second connector is located between the first connector and the third connector;

[0016] The second connector is slidably connected to the first connector via the groove and the slider extending along the second direction, and the second connector is slidably connected to the third connector via the groove and the slider extending along the third direction, wherein the first direction, the second direction and the third direction intersect each other.

[0017] Optionally, the connector is an annular structure and is sleeved on the lead screw. The inner diameter of the connector is larger than the cross-sectional area of ​​the lead screw, and the at least two connectors are arranged in a direction parallel to the axis of the lead screw.

[0018] Optionally, the lead screw nut includes a base plate and a protruding cylinder, the base plate having a through hole for the lead screw to pass through, and the protruding cylinder being connected to the base plate and arranged around the through hole;

[0019] At least two connectors are fitted onto the convex cylinder, and one connector is connected to the base plate, while the inner diameter of the remaining connectors is larger than the outer diameter of the convex cylinder.

[0020] Alternatively, both of the at least two connectors are located on the side of the base plate facing away from the convex cylinder, and one of the connectors is integrally formed with the base plate.

[0021] Optionally, the adjustment structure includes a flexible element, at least a portion of which is disposed between the wall of the mounting hole and the lead screw nut.

[0022] Optionally, the stage has four corner areas and a mounting hole in each corner area; the number of lead screw assemblies is four, and each lead screw assembly is located in one corner area.

[0023] The processing equipment also includes two drive mechanisms, each drive mechanism comprising a drive element, a drive wheel, two driven wheels, and a belt;

[0024] The driving wheel is connected to the driving member, each driven wheel is connected to a lead screw, and the belt is wound around the driving wheel and the driven wheels on two adjacent lead screws, so that each driving member drives the two adjacent lead screws to rotate.

[0025] The processing equipment of this application incorporates an adjustment structure between the stage and the lead screw nut of the lead screw assembly, allowing the lead screw nut to move relative to the stage in a direction intersecting the lead screw axis. When there is a misalignment between the fixed position of the lead screw assembly at its end and the mounting hole on the stage through which the lead screw passes, the relative movement of the stage and the lead screw nut in the direction intersecting the lead screw axis can be used for alignment adjustment. This reduces the possibility of uneven force on the lead screw assembly due to radial compression from the stage, which could cause jamming in the drive of the stage, thus improving the smoothness of the lead screw assembly's drive of the stage.

[0037] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0042] In related technologies, processing equipment often uses a worktable that is driven and raised by a lead screw assembly to facilitate the processing of workpieces of varying heights. Furthermore, to ensure accurate and smooth lifting of the worktable, guide rods are typically installed to guide its movement. These guide rods are usually made of stainless steel, are heavy, require a high degree of surface finish, and need to be used with precision linear bearings, thus increasing the manufacturing cost of this part of the mechanism. Additionally, guide rods and lead screws often exist in pairs, requiring a certain installation distance between them to ensure that the movement of the lead screw nut and the linear bearing on the guide rod does not interfere with each other, further increasing the space occupied by this part of the mechanism.

[0043] Therefore, in order to simplify the structure, reduce costs, and minimize space occupation, an attempt was made to eliminate the guide rod and use a lead screw that serves both driving and guiding functions. However, due to factors such as manufacturing and installation errors, and the lack of a guide rod, the alignment of the lead screw assembly's fixed position at its end with the mounting hole on the platform through which the lead screw assembly passes is prone to deviation. This leads to uneven stress on the lead screw assembly in the radial direction due to the platform's compressive force, causing the platform's drive to become jerky.

[0044] Therefore, based on the above considerations, in order to improve the smoothness of the lead screw assembly's drive of the stage, this application proposes a processing device.

[0045] Please refer to the reference. Figures 1 to 6In one embodiment of this application, the processing equipment 100 includes a body 10, a lead screw assembly 20, a stage 30, and an adjustment structure 40. The lead screw assembly 20 includes a lead screw 21 and a lead screw nut 23. The lead screw 21 is rotatably mounted on the body 10, and the lead screw nut 23 is sleeved on the lead screw 21. The stage 30 is provided with a mounting hole 31, through which the lead screw 21 passes. The adjustment structure 40 is provided between the stage 30 and the lead screw nut 23 so that the lead screw nut 23 can move relative to the stage 30 in a direction intersecting the axis of the lead screw 21.

[0046] The body 10 can be used to provide mounting positions for the lead screw assembly 20 and the stage 30. The body 10 can be a shell structure to allow for the internal mounting of the lead screw assembly 20 and the stage 30, thus providing isolation and protection for them. Of course, the body 10 can also be a single-unit structure, a single-plate structure, or a frame structure, etc. This application does not limit the structural type of the body 10.

[0047] The lead screw assembly 20 can be used to drive the stage 30 to move along an axis parallel to the lead screw 21. Specifically, after the lead screw 21 is driven to rotate, since the lead screw nut 23 is connected to the lead screw nut 23, it can move along an axis parallel to the lead screw 21, thereby driving the stage 30 to move. When the processing equipment 100 is in normal installation and use, with the ground as a reference, the lead screw 21 can extend vertically, horizontally, or in an inclined direction intersecting the vertical and horizontal directions. Furthermore, the number of lead screw assemblies 20 can be one, two, or more; this application does not limit the number of lead screw assemblies 20.

[0048] The stage 30 can be used to support workpieces. The plane of the stage 30 can intersect with the axis parallel to the lead screw 21. The stage 30 can be a plate structure or a disc structure; this application does not limit the structural type of the stage 30. Furthermore, the mounting hole 31 on the stage 30 can be used to avoid the lead screw 21. Therefore, to facilitate the avoidance of the lead screw 21, the area of ​​the mounting hole 31 can be set to be larger than the cross-sectional area of ​​the lead screw 21. Of course, in some embodiments, the lead screw nut 23 can also extend into the mounting hole 31. In this case, the mounting hole 31 can also be used to avoid the lead screw nut 23. Therefore, to facilitate the avoidance of the lead screw 21, the area of ​​the mounting hole 31 can be set to be larger than the cross-sectional area of ​​the lead screw nut 23.

[0049] The adjustment structure 40 can be disposed between the stage 30 and the lead screw nut 23, allowing them to move relative to each other in a direction intersecting the axis of the lead screw 21. Specifically, when the lead screw 21 extends vertically, the adjustment structure 40 allows the stage 30 and the lead screw nut 23 to move relative to each other in the horizontal direction. Furthermore, the direction parallel to the axis of the lead screw 21 is defined as the first direction, and the horizontal direction may include a second direction and a third direction, with each of the first, second, and third directions intersecting. In this case, the stage 30 and the lead screw nut 23 can move relative to each other only in the second direction, only in the third direction, or in both the second and third directions. In addition, the adjustment structure 40 enables the stage 30 and the lead screw nut 23 to move and adjust in the horizontal direction. This can be achieved by the lead screw nut 23 being slidably mounted on the stage 30 through the adjustment structure 40, as described below. Alternatively, the adjustment structure 40 can be configured to include a flexible component, such as a silicone component or a rubber component, so that the adjustment structure 40 can deform under pressure to allow the stage 30 and the lead screw nut 23 to move and adjust relative to each other.

[0050] The processing head can be used to process a workpiece placed on the stage 30. The processing head and the stage 30 are arranged along a first direction, and the lead screw assembly 20 can drive the stage 30 to approach or manage the processing head. Furthermore, the processing head can include at least one of a laser head, a cutting tool head, a printing cartridge, and a drawing pen; of course, it can also be other types of processing tools. This application does not limit the type of processing head.

[0051] The processing equipment 100 of this application has an adjustment structure 40 between the stage 30 and the lead screw nut 23 of the lead screw assembly 20, allowing the stage 30 and the lead screw nut 23 to move relative to each other in a direction intersecting the axis of the lead screw 21. When there is a misalignment between the fixed position of the lead screw assembly 20 at its end and the mounting hole 31 on the stage 30 through which the lead screw 21 passes, the alignment can be adjusted by the relative movement of the stage 30 and the lead screw nut 23 in the direction intersecting the axis of the lead screw 21. This reduces the possibility of uneven force on the lead screw assembly 20 due to the radial pressure from the stage 30, which could cause jamming in the drive of the stage 30, and thus improves the smoothness of the drive of the stage 30 by the lead screw assembly 20.

[0052] Please refer to the reference. Figures 4 to 6In one embodiment of this application, at least a portion of the lead screw nut 23 and the adjustment structure 40 are located outside the mounting hole 31, and the adjustment structure 40 is connected to the stage 30 and the lead screw nut 23 respectively, so that the lead screw nut 23 is slidably mounted on the stage 30 in a direction intersecting the axis of the lead screw 21.

[0053] When the first direction is vertical as described above, and the processing head is above the stage 30, at least a portion of the lead screw nut 23 can be located below the mounting hole 31, and the adjustment structure 40 can be set between the lower surface of the stage 30 and the lead screw nut 23. Furthermore, the lead screw nut 23 is slidably mounted on the stage 30 in the direction intersecting the axis of the lead screw 21. This can be achieved by partially connecting the adjustment structure 40 to the stage 30 and partially connecting it to the lead screw nut 23, with the portion connected to the stage 30 and the portion connected to the lead screw nut 23 being slidably connected. For example, the adjustment structure 40 may include a connecting member 41 as described below. Alternatively, it can be achieved by configuring the adjustment structure 40 to include a sliding connection structure, such as configuring the adjustment structure 40 to include a sliding slider and a sliding groove, one of which is disposed on the lead screw nut 23 and the other is directly disposed on the stage 30. Alternatively, it can be achieved by slidably connecting the lead screw nut 23 to the adjustment structure 40; or by slidably connecting the stage 30 to the adjustment structure 40. In other words, the structural type of the adjustment structure 40 is not limited, as long as the lead screw nut 23 and the stage 30 can be relatively slidably adjusted in the direction intersecting the axis of the lead screw 21, i.e., the second direction and / or the third direction described above.

[0054] In this embodiment, at least a portion of the lead screw nut 23 and the adjusting structure 40 are both disposed outside the mounting hole 31, facilitating the sliding installation of the lead screw nut 23 on the stage 30. This sliding installation improves the stability of the relative movement adjustment between the lead screw nut 23 and the stage 30, as well as the overall stability of the connection, while allowing relative movement adjustment between them in directions intersecting the axis of the lead screw 21.

[0055] Please refer to the reference. Figures 4 to 6 In one embodiment of this application, the adjustment structure 40 includes at least two connectors 41, one connector 41 is connected to the platform 30, and the other connector 41 is connected to the lead screw nut 23, with adjacent connectors 41 being slidably connected.

[0056] The number of connectors 41 can be two, or three or more. Furthermore, two of the connectors 41 are respectively connected to the stage 30 and the lead screw nut 23, and the connection method between the connectors 41 and the stage 30 and the lead screw nut 23 can be a through screw connection, a through pin connection, or an adhesive connection. This application does not limit the connection method between the connectors 41 and the stage 30 and the lead screw nut 23. Any two adjacent connectors 41 can be slidably connected, and the sliding direction can be a second direction or a third direction. In addition, the connectors 41 can be a ring structure, or a rectangular structure, etc. This application does not limit the structural type of the connectors 41.

[0057] In this embodiment, the adjustment structure 40 is configured to include at least two connectors 41, which are respectively connected to the stage 30 and the lead screw nut 23. The sliding connection between the connectors 41 allows for the sliding installation of the lead screw nut 23 and the stage 30. In this case, the structure of the connectors 41 is relatively simple and its volume is relatively small, thus facilitating the implementation of the sliding connection structure. Simultaneously, it eliminates the need for a sliding connection structure on the stage 30 and the lead screw nut 23, which helps protect the structural design of the stage 30 and the lead screw nut 23 themselves.

[0058] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, in two adjacent connectors 41, one is provided with a groove 411 and the other is provided with a slider 413; the groove 411 extends along a direction intersecting the axis of the lead screw 21, and the slider 413 is slidably installed in the groove 411.

[0059] In this embodiment, the cooperation of the groove 411 and the slider 413 guides the sliding direction between two adjacent connecting parts 41, so as to accurately adjust the movement of the lead screw nut 23 and the platform 30 in the direction intersecting the axis of the lead screw 21. Of course, in other embodiments, one of the two adjacent connecting parts 41 may be provided with two baffles, both of which extend along the sliding direction and abut against the opposite sides of the other to achieve a sliding connection between the two adjacent connecting parts 41.

[0060] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, the groove 411 is a T-groove or a dovetail groove, and the shape of the slider 413 is adapted to the shape of the groove 411.

[0061] In this embodiment, the slide groove 411 is a T-groove or a dovetail groove, which limits the movement of two adjacent connecting parts 41 in a direction parallel to the axis of the lead screw 21, thereby improving the stability of the sliding connection between the two adjacent connecting parts 41. Of course, in other embodiments, the slide groove 411 can also be a U-groove or a V-groove, etc.

[0062] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, the number of connectors 41 can be three, and they are respectively defined as a first connector 41A, a second connector 41B, and a third connector 41C. The second connector 41B is located between the first connector 41A and the third connector 41C. The second connector 41B is slidably connected to the first connector 41A via a slide groove 411 and a slider 413 extending along a second direction, and the second connector 41B is slidably connected to the third connector 41C via a slide groove 411 and a slider 413 extending along a third direction.

[0063] In this embodiment, the number of connectors 41 is set to three, which can prevent the number of connectors 41 from being too large, thereby simplifying the structural setup of the adjustment structure 40. Furthermore, the middle connector 41 and the connectors 41 at both ends can form different sliding directions, namely the second direction and the third direction, thereby enabling the lead screw nut 23 and the platform 30 to move and adjust relative to each other in two intersecting directions in the horizontal direction, improving the movement and adjustment effect.

[0064] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, the connector 41 is a ring structure and is sleeved on the lead screw 21, and at least two connectors 41 are arranged in a direction parallel to the axis of the lead screw 21.

[0065] In this embodiment, the connector 41 is configured as an annular structure sleeved on the lead screw 21, which restricts the horizontal sliding stroke of the connector 41 by the lead screw 21, reducing the possibility of the connector 41 sliding off. To allow the connector 41 to have a sliding stroke, the inner diameter of the connector 41 can be larger than the cross-sectional area of ​​the lead screw 21.

[0066] Please refer to the reference. Figure 5 and Figure 6In one embodiment of this application, the lead screw nut 23 may include a base plate 233 and a protruding cylinder 235. The base plate 233 is provided with a through hole for the lead screw 21 to pass through, and the protruding cylinder 235 protrudes from the base plate 233 and surrounds the through hole. In this case, in order to improve the compactness of the distribution between the adjusting structure 40 and the lead screw nut 23, each connecting member 41 can be sleeved on the protruding cylinder 235, and one connecting member 41 is connected to the base plate 233. The inner diameter of the remaining connecting members 41 is larger than the outer diameter of the protruding cylinder 235, so that there is a sliding stroke between adjacent connecting members 41.

[0067] Please refer to the reference. Figure 7 and Figure 8 In one embodiment of this application, the connector 41 and the base plate 233 can be integrally formed to reduce the number of parts in the processing equipment 100. In this case, to facilitate the sliding installation of the connector 41 integrated with the base plate 233 and the other connectors 41, each connector 41 can be disposed on the side of the base plate 233 facing away from the protrusion 235.

[0068] In one embodiment of this application, the adjustment structure 40 includes a flexible member, at least a portion of which is disposed between the wall of the mounting hole 31 and the lead screw nut 23.

[0069] In this embodiment, the adjustment structure 40 is configured to include a flexible component, eliminating the need for a connecting structure between the stage 30 and the lead screw nut 23, thus simplifying the structural design. The flexible component can be made of rubber or silicone, etc. Furthermore, for ease of installation, the flexible component can be ring-shaped to fit over the lead screw 21 or lead screw nut 23.

[0070] Please refer to the reference. Figures 1 to 4 In one embodiment of this application, the number of lead screw assemblies 20 is at least two, the platform 30 is provided with at least two mounting holes 31, the lead screw 21 in the lead screw assembly 20 passes through a mounting hole 31, and an adjustment structure 40 is provided between the platform 30 and at least one lead screw nut 23.

[0071] In this embodiment, setting the number of lead screw assemblies 20 to at least two can improve the driving force and driving stability of the stage 30. In this case, an adjustment structure 40 can be provided between only one lead screw nut 23 and the stage 30, or a conditional structure can be provided between two or more lead screw nuts 23 and the stage 30.

[0072] Please refer to the reference. Figure 1 and Figure 2In one embodiment of this application, the stage 30 is provided with four corner areas 33, and each corner area 33 is provided with a mounting hole 31. The number of lead screw assemblies 20 is four, and each lead screw assembly 20 is provided in one corner area 33. The processing equipment 100 also includes two drive mechanisms 50. The drive mechanism 50 includes a drive member 51, a drive wheel 53, two driven wheels 55 and a belt 57. The drive wheel 53 is connected to the drive member 51, each driven wheel 55 is connected to a lead screw 21, and the belt 57 is wound around the drive wheel 53 and the driven wheels 55 on the two adjacent lead screws 21, so that each drive member 51 drives the two adjacent lead screws 21 to rotate.

[0073] In this embodiment, lead screw assemblies 20 are provided at each of the four corner areas 33 of the stage 30, which can improve the driving force and driving stability of the stage 30. Furthermore, two driving mechanisms 50 are provided so that two adjacent lead screw assemblies 20 can be driven by one driving mechanism 50. This can shorten the length of the belt 57, which only needs to be wound around the driven pulley 55 and the driving pulley 53 on the two lead screws 21. This prevents the shrinkage deformation of the belt 57 from being too large, thereby improving the accuracy and efficiency of the belt 57 transmission and reducing the likelihood of lag in the driving of the lead screw assemblies 20.

[0074] Please refer to Figure 6 In one embodiment of this application, the connector 41 may be provided with a first connecting hole 417, so that when the lead screw nut 23 and the platform 30 do not need to be moved or adjusted in the second or third direction, screws or pins are inserted into the first connecting hole 417 in two adjacent connectors 41 to lock the two connectors 41. When the lead screw nut 23 is formed integrally with a connector 41 as described above, please refer to... Figure 7 The integrated structure formed by the lead screw nut 23 and the connector 41 can also have a second connecting hole 2331 at the position corresponding to the first connecting hole 417, so that screws or pins can be inserted to lock the integrated structure and the other connectors 41.

[0075] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
