Description

Technical Field

[0001] The present disclosure relates to the field of automation technologies, and particularly to an automated two-stage telescopic platform. Background Art

[0002] Telescopic platforms are widely used in engineering, and are used in a very large number of construction machinery. In the field of application of automated equipment, the telescopic platform performs translational motion under the driving force of the power unit to convey articles. However, in actual applications, the working radius is directly determined by the length of the telescopic platform itself. Ordinary telescopic platforms usually can only extend one section, and the ratio of the extended length to the length in the retracted state is at most 2, resulting in extremely limited extension of the telescopic platform and unable to achieve the expected effect.

[0003] Existing two-stage telescopic platforms can achieve twice the extension distance under the same structural volume and perform automated operations in equipment with extremely limited space. However, currently, two-stage telescopic platforms often require two drive devices and multiple transmission devices to drive the two telescopic plates respectively, making the structure of the telescopic platform complex. Summary of the Utility Model

[0004] Based on this, in view of the above problems, it is necessary to provide an automated two-stage telescopic platform.

[0005] An embodiment of the present disclosure provides an automated two-stage telescopic platform, which includes a fixed plate, a first telescopic plate, and a second telescopic plate that are vertically stacked in sequence and slidably connected to each other; the automated two-stage telescopic platform further includes a drive assembly, a first transmission assembly, and a second transmission assembly. The drive assembly and the first transmission assembly are fixed to the fixed plate, and the drive assembly is used to drive the first transmission assembly to drive the first telescopic plate to slide relative to the fixed plate along the sliding direction; the second transmission assembly is fixed to the first telescopic plate, and the second transmission assembly is connected to the fixed plate and the second telescopic plate so that the second telescopic plate slides relative to the fixed plate and the first telescopic plate along the sliding direction.

[0006] The automated two-stage telescopic platform provided by the embodiments of the present disclosure has a fixed plate that remains stationary. The driving component and the first transmission component are fixed to the fixed plate. The driving component drives the first transmission component to make the first telescopic plate slide relative to the fixed plate. The second transmission component is fixed to the first telescopic plate and is connected to the fixed plate and the second telescopic plate at the same time. When the first telescopic plate moves relative to the fixed plate, the second transmission component moves to drive the second telescopic plate to slide relative to the fixed plate and the first telescopic plate. At this time, only one driving device can realize the telescoping of the first telescopic plate and the second telescopic plate relative to the fixed plate, achieving a longer telescopic distance within a limited space. Moreover, when the first telescopic plate telescopes, only the driving member needs to drive the first transmission component to move. The two-stage telescoping is completed only through two transmission components at the same time, simplifying the power connection, making the structure of the automated two-stage telescopic platform simple and compact, and facilitating the telescoping of the first telescopic plate and the second telescopic plate relative to the fixed plate.

[0007] In some of these embodiments, the first transmission component includes two first synchronous pulleys arranged side by side along the sliding direction, a first synchronous belt connecting the two first synchronous pulleys, and a first toothed plate. The central axis direction of the first synchronous pulley is horizontal, and one end of the first toothed plate is connected to the synchronous belt, and the other end is connected to the first telescopic plate.

[0008] With this arrangement, when the two first synchronous pulleys rotate around the horizontal direction, the first synchronous belt can move along the sliding direction, and the first toothed plate follows the first synchronous belt to drive the first telescopic plate to expand and contract along the sliding direction. The rotation accuracy of the first synchronous pulley is high and the stability is good, ensuring the position accuracy and movement stability of the first telescopic plate.

[0009] In some of these embodiments, an installation groove is provided at the middle position of the fixed plate, and the first transmission component is located in the installation groove.

[0010] With this arrangement, it is convenient for the first transmission component to connect the fixed plate and the first telescopic plate, facilitating the telescoping of the first telescopic plate along the sliding direction. At the same time, the space and volume of the automated two-stage telescopic platform are reduced, which is beneficial for automated operations in equipment with extremely limited space.

[0011] In some of these embodiments, the second transmission component includes two second synchronous pulleys arranged side by side along the sliding direction, a second synchronous belt connecting the two second synchronous pulleys, a second outer toothed plate, and a second inner toothed plate. The central axis direction of the second synchronous pulley is vertical; one end of the second outer toothed plate is connected to the outside of the second synchronous belt and the other end is fixed to the fixed plate; one end of the second inner toothed plate is connected to the inside of the second synchronous belt and the other end is connected to the second telescopic plate.

[0012] With such a setting, before the second synchronous pulley and the second synchronous belt in the second transmission assembly move along the sliding direction following the first telescopic plate, the second synchronous pulley and the second synchronous belt are stationary without relative movement at this time; when the first telescopic plate expands and contracts, since the second external tooth plate remains stationary and the second external tooth plate is connected to the outer side of the second synchronous belt, a reverse force is applied to the outer side of the second synchronous belt to move in the reverse direction of the sliding direction relative to the first telescopic plate, driving the second synchronous pulley to rotate, and the inner side of the second synchronous belt moves along the sliding direction, driving the second telescopic plate to move along the sliding direction. At this time, the driving assembly, the first transmission assembly, and the second transmission assembly achieve the linkage expansion and contraction of the first telescopic plate and the second telescopic plate, shortening the time to reach the extended position, improving work efficiency, and ensuring the position accuracy of the expansion and contraction.

[0013] In some of the embodiments, there are two second transmission assemblies, and the two second transmission assemblies are located at both ends of the first telescopic plate perpendicular to the sliding direction.

[0014] With such a setting, it avoids the deformation caused by uneven forces at both ends of the second telescopic plate perpendicular to the sliding direction, and ensures the stability and accuracy of the movement of the second telescopic plate during expansion and contraction.

[0015] In some of the embodiments, the automated two-stage telescopic platform further includes a first sliding connection assembly. The first sliding connection assembly includes a first slide rail and a first slider movably connected to the first slide rail. The first slide rail is fixed to one side of the fixed plate facing the first telescopic plate and extends along the sliding direction, and the first slider is connected to one side of the first telescopic plate facing the fixed plate.

[0016] With such a setting, the first slide rail has good lateral guiding performance and is not easily deformed. The cooperation structure between the first slide rail and the first slider is simple, ensuring the accuracy of the movement of the first telescopic plate along the sliding direction. Moreover, the friction between the first slider and the first slide rail is small, ensuring the stability of the telescopic movement.

[0017] In some of the embodiments, the automated two-stage telescopic platform further includes a second sliding connection assembly. The second sliding connection assembly includes a second slide rail and a second slider movably connected to the second slide rail. The second slide rail is fixed to one side of the first telescopic plate facing the second telescopic plate and extends along the sliding direction, and the second slider is connected to one side of the second telescopic plate facing the first telescopic plate.

[0018] With such a setting, the second slide rail has good lateral guiding performance and is not easily deformed. The cooperation structure between the second slide rail and the second slider is simple, ensuring the accuracy of the movement of the second telescopic plate along the sliding direction. Moreover, the friction between the second slider and the second slide rail is small, ensuring the stability of the telescopic movement.

[0019] In some of these embodiments, two first limit members protrude from the upper surface of the fixed plate, and the two first limit members are distributed at both ends of the fixed plate perpendicular to the sliding direction; a plurality of second limit members protrude from the upper surface of the second telescopic plate, and the plurality of second limit members are symmetrically distributed at both ends of the second telescopic plate along the sliding direction.

[0020] With such a setting, the first limit member and the second limit member can limit the article in the horizontal direction to ensure the relative position of the article during automatic storage and retrieval of the article and prevent the article from falling.

[0021] In some of these embodiments, the drive assembly includes a drive member and a speed reducer. The fixed end of the drive member is fixed to the fixed plate, and the drive end of the drive member is connected to the first transmission assembly through the speed reducer.

[0022] With such a setting, the speed reducer can reduce the output speed of the drive member, increase the torque, and enhance the load capacity, so that the first transmission assembly achieves an ideal transmission effect and ensures the stability of the movement of the first telescopic plate and the second telescopic plate.

[0023] In some of these embodiments, the materials of the fixed plate, the first telescopic plate, and the second telescopic plate are all aluminum alloy materials.

[0024] With such a setting, the aluminum alloy material can ensure the overall structural strength of the automatic two-stage telescopic platform and ensure that the automatic two-stage telescopic platform can bear a large load. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Refer to Figure 1 , Figure 1 which shows the overall structure of the automated two - stage telescopic platform 100 in the embodiments of the present disclosure. The present disclosure relates to the field of automation technology.

[0037] Combined with Figures 2 to 4 , the embodiments of the present disclosure provide an automated two - stage telescopic platform 100, which includes a fixed plate 1, a first telescopic plate 2, and a second telescopic plate 3 that are slidably connected to each other, and the fixed plate 1, the first telescopic plate 2, and the second telescopic plate 3 are stacked in sequence vertically. Exemplarily, the Z - axis direction is vertical, the fixed plate 1 is located at the lowermost layer, and the second telescopic plate 3 is located at the uppermost layer.

[0038] The automated two-stage telescopic platform 100 further includes a drive assembly 4, a first transmission assembly 5, and a second transmission assembly 6. The drive assembly 4 and the first transmission assembly 5 are fixed to the fixed plate 1. The drive assembly 4 is used to drive the first transmission assembly 5 to drive the first telescopic plate 2 to slide relative to the fixed plate 1 along the sliding direction. Exemplarily, the first transmission assembly 5 moves in the X-axis direction so that the sliding direction of the first telescopic plate 2 is the direction of the X-axis. The second transmission assembly 6 is fixed to the first telescopic plate 2. The second transmission assembly 6 is connected to the fixed plate 1 and the second telescopic plate 3 so that the second telescopic plate 3 slides relative to the fixed plate 1 and the first telescopic plate 2 along the sliding direction. Exemplarily, the second transmission assembly 6 also moves in the X-axis direction so that the sliding direction of the second telescopic plate 3 is along the X-axis direction relative to the fixed plate 1 and the first telescopic plate 2.

[0039] In the automated two-stage telescopic platform 100 provided by the embodiment of the present disclosure, the fixed plate 1 is fixed and immovable. The drive assembly 4 and the first transmission assembly 5 are fixed to the fixed plate 1. The drive assembly 4 drives the first transmission assembly 5 to make the first telescopic plate 2 slide relative to the fixed plate 1. The second transmission assembly 6 is fixed to the first telescopic plate 2 and can move along with the first telescopic plate 2. At the same time, the second transmission assembly 6 is connected to the fixed plate 1 and the second telescopic plate 3. When the first telescopic plate 2 moves relative to the fixed plate 1, the second transmission assembly 6 moves to drive the second telescopic plate 3 to slide relative to the fixed plate 1 and the first telescopic plate 2. At this time, only one driving device is needed to realize the telescoping of the first telescopic plate 2 and the second telescopic plate 3 relative to the fixed plate 1, achieving a longer telescoping distance in a limited space. Moreover, when the first telescopic plate 2 telescopes, only the driving member 41 needs to drive the first transmission assembly 5 to move. The two-stage telescoping is completed simultaneously only by driving two transmission assemblies, simplifying the power connection and making the structure of the automated two-stage telescopic platform 100 simple and compact, facilitating the telescoping of the first telescopic plate 2 and the second telescopic plate 3 relative to the fixed plate 1.

[0040] At the same time, the displacement of the first telescopic plate 2 relative to the fixed plate 1 is equal to the displacement of the second telescopic plate 3 relative to the first telescopic plate 2, that is, the second telescopic plate 3 has twice the displacement relative to the fixed plate 1, achieving a longer telescoping distance in a limited space.

[0041] Exemplarily, the drive assembly 4 is fixed to the lower side of the fixed plate 1. A first transmission assembly 5 is connected between the fixed plate 1 and the first telescopic plate 2. A second transmission assembly 6 is connected between the first telescopic plate 2 and the second telescopic plate 3.

[0042] Exemplarily, the projected profiles of the fixed plate 1, the first telescopic plate 2, and the second telescopic plate 3 along the Z-axis direction are all square. The dimensions of the fixed plate 1, the first telescopic plate 2, and the second telescopic plate 3 along the X-axis direction are greater than those along the Y-axis direction. In other embodiments, the projected profiles of the fixed plate 1, the first telescopic plate 2, and the second telescopic plate 3 can be circular, triangular, polygonal, or other irregular shapes. The projected profiles of the fixed plate 1, the first telescopic plate 2, and the second telescopic plate 3 can be different.

[0043] Exemplarily, the projection of the fixed plate 1 along the Z-axis direction is larger than the projection of the first telescopic plate 2 along the Z-axis direction; the projected profile of the first telescopic plate 2 along the Z-axis direction is larger than the projected profile of the second telescopic plate 3 along the Z-axis direction. In other embodiments, the projected profiles of the fixed plate 1, the first telescopic plate 2, and the second telescopic plate 3 along the Z-axis direction are the same. Or the projected profile of the second telescopic plate 3 along the Z-axis direction is the largest.

[0044] Exemplarily, the first telescopic plate 2 and the second telescopic plate 3 move relative to the fixed plate 1 along the X-axis direction. In other embodiments, the first telescopic plate 2 and the second telescopic plate 3 can move relative to the fixed plate 1 along the Y-axis direction. The movement directions of the first telescopic plate 2 and the second telescopic plate 3 are the same.

[0045] Reference Figures 1 to 4 , in some of these embodiments, the first transmission assembly 5 includes two first synchronous pulleys 51 arranged side by side along the sliding direction, a first synchronous belt 52 connecting the two first synchronous pulleys 51, and a first toothed plate 53. The central axis direction of the first synchronous pulley 51 is the horizontal direction. One end of the first toothed plate 53 is connected to the synchronous belt, and the other end of the first toothed plate 53 is connected to the first telescopic plate 2. With such a setting, when the two first synchronous pulleys 51 rotate around the horizontal direction, the first synchronous belt 52 can move along the sliding direction, and the first toothed plate 53 follows the movement of the first synchronous belt 52 to drive the first telescopic plate 2 to expand and contract along the sliding direction. The rotation accuracy of the first synchronous pulley 51 is high and the stability is good, ensuring the position accuracy and movement stability of the first telescopic plate 2.

[0046] Exemplarily, the two first synchronous pulleys 51 are arranged side by side along the X-axis direction. The central axis direction of the two first synchronous pulleys 51 is the Y-axis direction. The first synchronous belt 52 is sleeved outside the two first synchronous pulleys 51 along the X-axis direction. The surface of the first synchronous belt 52 remains horizontal. The lower end of the first toothed plate 53 is fixed to the upper surface of the upper side of the first synchronous belt 52, and the upper end of the first toothed plate 53 is fixed to the first telescopic plate 2; when the first synchronous pulley 51 rotates clockwise or counterclockwise around the Y-axis direction, the first synchronous belt 52 can move along the positive or negative direction of the X-axis under the drive of the first synchronous pulley 51. At this time, the first toothed plate 53 drives the first telescopic plate 2 to follow the first synchronous belt 52 to move along the positive or negative direction of the X-axis.

[0047] Exemplarily, the portion of the first synchronous belt 52 connected to the first toothed plate 53 has a shape that matches the first toothed plate 53. For example, the first synchronous belt 52 is a synchronous toothed belt, which facilitates the installation and cooperation with the first toothed plate 53.

[0048] Reference Figures 1 to 4 , in some of these embodiments, an installation groove 11 is provided at the middle position of the fixed plate 1, and the first transmission assembly 5 is located in the installation groove 11. With this arrangement, it is convenient for the first transmission assembly 5 to connect the fixed plate 1 and the first telescopic plate 2, facilitating the telescopic movement of the first telescopic plate 2 along the sliding direction. At the same time, the space and volume of the automated two-stage telescopic platform 100 are reduced, which is beneficial for automated operations in equipment with extremely limited space.

[0049] Exemplarily, the dimension of the installation groove 11 extending along the X-axis is greater than the dimension of the first synchronous belt 52 extending along the X-axis, and the dimension of the installation groove 11 along the Y-axis is greater than the dimension of the first synchronous belt 52 along the Y-axis. The upper surface of the first synchronous belt 52 is lower than the lower surface of the fixed plate 1, so that the first toothed plate 53 can move along the X-axis direction within the installation groove 11.

[0050] Reference Figures 1 to 4 , in some of these embodiments, the second transmission assembly 6 includes two second synchronous pulleys 61 arranged side by side along the sliding direction, a second synchronous belt 62 connecting the two second synchronous pulleys 61, a second outer toothed plate 63, and a second inner toothed plate 64. The central axis direction of the second synchronous pulley 61 is the vertical direction; one end of the second outer toothed plate 63 is connected to the outside of the second synchronous belt 62 and the other end is fixed to the fixed plate 1; one end of the second inner toothed plate 64 is connected to the inside of the second synchronous belt 62 and the other end is connected to the second telescopic plate 3. Before the second synchronous pulley 61 and the second synchronous belt 62 in the second transmission assembly 6 move along the sliding direction following the first telescopic plate 2, at this time, the second synchronous pulley 61 and the second synchronous belt 62 do not move relative to each other and remain stationary; when the first telescopic plate 2 expands and contracts, since the second outer toothed plate 63 remains stationary and the second outer toothed plate 63 is connected to the outside of the second synchronous belt 62, a reverse force is applied to the outside of the second synchronous belt 62 to move in the reverse direction of the sliding direction relative to the first telescopic plate 2, driving the second synchronous pulley 61 to rotate, and the inside of the second synchronous belt 62 moves along the sliding direction, driving the second telescopic plate 3 to move along the sliding direction. With this arrangement, at this time, the drive assembly 4, the first transmission assembly 5, and the second transmission assembly 6 achieve the linkage expansion and contraction of the first telescopic plate 2 and the second telescopic plate 3, shortening the time to reach the extended position, improving work efficiency, and ensuring the position accuracy of the expansion and contraction.

[0051] Exemplarily, both the second synchronous pulley 61 and the second synchronous belt 62 are located on the upper side of the first telescopic plate 2. The two second synchronous pulleys 61 are arranged side by side in the X-axis direction, and the central axis direction of the two second synchronous pulleys 61 is the Z-axis direction. The second synchronous belt 62 is sleeved outside the two first synchronous pulleys 51 in the X-axis direction, and the surface of the second synchronous belt 62 is in the vertical direction. The upper end of the second external tooth plate 63 is fixed to the outer surface of the second synchronous belt 62, and the lower end of the second external tooth plate 63 is fixed to the fixed plate 1; the lower end of the second internal tooth plate 64 is connected to the inner surface of the second synchronous belt 62, and the upper end of the second internal tooth plate 64 is connected to the lower surface of the second telescopic plate 3. When the first telescopic plate 2, the first synchronous belt 52 and the first synchronous pulley 51 move in the positive X-axis direction, since the second external tooth plate 63 remains stationary and is subjected to a force in the positive X-axis direction, the outer side of the first synchronous belt 52 is subjected to a force in the reverse X-axis direction and moves in the reverse X-axis direction, driving the second synchronous pulley 61 to rotate clockwise along the Z-axis. Then, the inner side of the first synchronous belt 52 moves in the positive X-axis direction. At this time, the second internal tooth plate 64 drives the second telescopic plate 3 to move in the positive X-axis direction along with the inner side of the second synchronous belt 62. When the first telescopic plate 2, the first synchronous belt 52 and the first synchronous pulley 51 move in the reverse X-axis direction, similarly to the above, only the movement direction changes.

[0052] Exemplarily, the part of the second synchronous belt 62 connected to the second external tooth plate 63 and the second internal tooth plate 64 has a matching installation shape. For example, the second synchronous belt 62 is a synchronous toothed belt, which is convenient for installation and cooperation with the second external tooth plate 63 and the second internal tooth plate 64.

[0053] Exemplarily, the first tooth plate 53, the second external tooth plate 63 and the second internal tooth plate 64 are all cuboids. The dimension of the second external tooth plate 63 in the Z-axis direction is higher than the distance between the upper surface of the fixed plate 1 and the upper surface of the first telescopic plate 2.

[0054] Reference Figures 1 to 4 , in some of the embodiments, there are two second transmission components 6. The two second transmission components 6 are arranged side by side in the Y-axis direction at both ends of the first telescopic plate 2. There are also two second external tooth plates 63. The second external tooth plates 63 are symmetrically arranged on both sides of the first telescopic plate 2 in the Y-axis direction. One second external tooth plate 63 is correspondingly connected to the outer surface of one second synchronous belt 62. With such an arrangement, the deformation caused by uneven force on both ends of the second telescopic plate 3 perpendicular to the sliding direction is avoided, ensuring the stability and accuracy of the movement of the second telescopic plate 3 during telescoping. The overall structure of the automated two-stage telescopic platform 100 is simple to install and occupies a small space.

[0055] Reference Figures 2 to 4, in some embodiments, the automated two - stage telescopic platform 100 further includes a first sliding connection assembly 7. The first sliding connection assembly 7 includes a first slide rail 71 and a first slider 72 movably connected to the first slide rail 71. The first slide rail 71 is fixed to one side of the fixed plate 1 facing the first telescopic plate 2 and extends along the sliding direction. The first slider 72 is connected to one side of the first telescopic plate 2 facing the fixed plate 1. With such a setting, the first slide rail 71 has good lateral guiding performance and is not easily deformed. The cooperation structure between the first slide rail 71 and the first slider 72 is simple, ensuring the accuracy of the movement of the first telescopic plate 2 along the sliding direction. Moreover, the friction between the first slider 72 and the first slide rail 71 is small, ensuring the stability of the telescopic movement.

[0056] Exemplarily, there are two first sliding connection assemblies 7, and the two first sliding connection assemblies 7 are respectively located on both sides of the installation groove 11 along the X - axis direction, and the first slide rail 71 extends along the X - axis direction.

[0057] Reference Figure 2 And Figure 4 , in some embodiments, the automated two - stage telescopic platform 100 further includes a second sliding connection assembly 8. The second sliding connection assembly 8 includes a second slide rail 81 and a second slider 82 movably connected to the second slide rail 81. The second slide rail 81 is fixed to one side of the first telescopic plate 2 facing the second telescopic plate 3 and extends along the sliding direction. The second slider 82 is connected to one side of the second telescopic plate 3 facing the first telescopic plate 2. With such a setting, the second slide rail 81 has good lateral guiding performance and is not easily deformed. The cooperation structure between the second slide rail 81 and the second slider 82 is simple, ensuring the accuracy of the movement of the second telescopic plate 3 along the sliding direction. Moreover, the friction between the second slider 82 and the second slide rail 81 is small, ensuring the stability of the telescopic movement.

[0058] Reference Figures 1 to 4 , in some embodiments, two first limit members 12 protrude from the upper surface of the fixed plate 1, and the two first limit members 12 are distributed at both ends of the fixed plate 1 along a direction perpendicular to the sliding direction; a plurality of second limit members 31 protrude from the upper surface of the second telescopic plate 3, and the plurality of second limit members 31 are symmetrically distributed at both ends of the second telescopic plate 3 along the sliding direction. With such a setting, the first limit members 12 and the second limit members 31 can limit the article in the horizontal direction to ensure the relative position of the article during automated access of the article and prevent the article from falling.

[0059] Exemplarily, the first limit members 12 are located at both ends of the fixed plate 1 along the Y - axis direction. The dimension of the first limit member 12 along the X - axis direction is the same as the dimension of the fixed plate 1 along the X - axis direction, and the height of the first limit member 12 along the Z - axis direction is higher than the dimension of the first telescopic plate 2 along the second direction.

[0060] Exemplarily, the second limiting members 31 are located at both ends of the fixing plate 1 in the X-axis direction. There are four second limiting members 31, and every two second limiting members 31 are located on one side. The second limiting members 31 are symmetrically arranged with respect to the Y-axis. In other embodiments, the second limiting members 31 can also be two, six or other numbers. Or there are two second limiting members 31, and the Y-axis dimension of each second limiting member 31 is equal to the Y-axis dimension of the second telescopic plate 3.

[0061] Exemplarily, the first limiting member 12 and the fixing plate 1 are of an integral structure. The second limiting member 31 and the second telescopic plate 3 are of an integral structure.
