Description

Technical Field

[0001] This application belongs to the field of mechanical automation technology, and specifically relates to a lifting and tilting mechanism. Background Technology

[0002] In automated processing, lifting and flipping mechanisms are commonly used to lift and flip materials. In traditional automatic lifting and flipping mechanisms, the lifting and rotation of the workpiece are each controlled by a separate power source, which not only increases costs but also makes it more difficult to adjust the lifting and flipping mechanism. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a lifting and tilting mechanism that can control the lifting and rotation of the workpiece plate through the same power component.

[0004] Embodiments of this application provide a lifting and tilting mechanism, including a base, a support plate, a linkage assembly, a transmission assembly, and a power assembly. The base includes a guide groove. The support plate has a bearing surface for bearing a workpiece. The linkage assembly is connected to the support plate and cooperates with the guide groove. The transmission assembly is connected to the linkage assembly. The power assembly is connected to the transmission assembly, and the power assembly drives the linkage assembly to move along the guide groove through the transmission assembly, thereby causing the support plate to lift and tilt relative to the base.

[0005] In the aforementioned lifting and tilting mechanism, the power component drives the transmission component to move the linkage component along the guide groove, enabling the support plate connected to the linkage component to lift and rotate the workpiece relative to the base. Therefore, controlling the lifting and rotation of the support plate with the same power component reduces the cost of the lifting and tilting mechanism, makes the structure of the lifting and tilting mechanism more compact, and reduces the difficulty of assembling and debugging the lifting and tilting mechanism.

[0006] In some embodiments, the guide groove includes a straight groove and an arc-shaped groove. The straight groove extends vertically to guide the linkage component to lift and lower the support plate. The arc-shaped groove connects to the straight groove and extends toward the side opposite to the base, and is used to guide the linkage component to rotate the support plate relative to the base.

[0007] In some embodiments, the linkage component includes a first rotating shaft, a second rotating shaft, a first cam, and a second cam. The first rotating shaft is rotatably connected to the support plate, and the second rotating shaft is fixedly connected to the support plate. The first cam is rotatably mounted on the first rotating shaft, and the second cam is rotatably mounted on the second rotating shaft. Both the first cam and the second cam are rotatably slidably connected to the guide groove. The transmission component, driven by the power component, pushes the second rotating shaft to move the first cam and the second cam along the straight groove until the second cam slides from the straight groove into the arc groove to rotate, thereby allowing the support plate to rise, fall, and flip relative to the base.

[0008] In some embodiments, the transmission assembly includes a transmission shaft, a first crank, and a second crank. The transmission shaft is used to connect to a power assembly. The second crank is rotatably connected to the first crank. The first crank is fixedly connected to the transmission shaft. The second crank is rotatably connected to a second rotating shaft. When the transmission shaft rotates, it drives the first crank to rotate and drives the second crank to push the second rotating shaft to rise and fall. The first rotating shaft rises and falls under the drive of the support plate until the second rotating shaft drives the support plate to rotate around the first rotating shaft.

[0009] In some embodiments, the first rotating shaft and the second rotating shaft are arranged at a preset distance interval. The second rotating shaft is used to drive the second cam to move along the arcuate groove and rotate around the first rotating shaft when the first rotating shaft drives the first cam to be pushed to the end of the straight groove.

[0010] In some embodiments, the power assembly includes a power source, a driving wheel, a driven wheel, and a belt. The power source is coaxially connected to the driving wheel, the driven wheel is coaxially connected to the drive shaft, and the belt is tensioned between the driving wheel and the driven wheel. The power source is used to drive the driving wheel to rotate, so that the belt drives the driven wheel and the drive shaft to rotate.

[0011] In some embodiments, the base includes a support platform, a buffer plate, and an adjustment component. The support platform and the buffer plate are spaced apart in a vertical direction, and the adjustment component is connected between the support platform and the buffer plate and is used to adjust the distance between the support platform and the buffer plate.

[0012] In some embodiments, a buffer plate is connected to a buffer, the buffer is connected to the buffer plate, and a support plate is connected to a mating member corresponding to the buffer. The mating member abuts against the buffer when the support plate rotates toward the base.

[0013] In some embodiments, the support plate is connected to a rib, which is located on the side of the support plate facing the base and is used to connect the linkage assembly.

[0014] In some embodiments, the base includes two side plates, each side plate having a guide groove, the two side plates being spaced apart on the support platform, and the linkage component and the transmission component being disposed between the two side plates; the support plate is connected to two ribs, the two ribs being spaced apart on the support plate, and both ribs being connected to the linkage component.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment.

[0031] It should be noted that the thickness, length, width and other dimensions of various components in the embodiments of this application shown in the accompanying drawings are merely illustrative and should not constitute any limitation on this application.

[0032] In automated processing, lifting and flipping mechanisms are commonly used to lift and flip materials. In traditional automatic lifting and flipping mechanisms, the lifting and rotation of the workpiece are each controlled by a separate power source, which not only increases costs but also makes it more difficult to adjust the lifting and flipping mechanism.

[0033] This application provides a lifting and tilting mechanism that controls the lifting and rotation of a workpiece plate via a single power component. The lifting and tilting mechanism includes a base, a support plate, a linkage component, a transmission component, and a power component. The base includes a guide groove. The support plate has a bearing surface for bearing the workpiece. The linkage component is connected to the support plate and engages with the guide groove. The transmission component is connected to the linkage component. The power component is connected to the transmission component, and the power component drives the linkage component to move along the guide groove via the transmission component, thereby causing the support plate to lift and tilt relative to the base.

[0034] In the aforementioned lifting and tilting mechanism, the power component drives the transmission component to move the linkage component along the guide groove, enabling the support plate connected to the linkage component to lift and rotate the workpiece relative to the base. Therefore, controlling the lifting and rotation of the support plate with the same power component reduces the cost of the lifting and tilting mechanism, makes the structure of the lifting and tilting mechanism more compact, and reduces the difficulty of assembling and debugging the lifting and tilting mechanism.

[0035] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] Please see Figure 1 This application provides a lifting and tilting mechanism 100, including a base 10, a support plate 20, a linkage assembly 30, a transmission assembly 40, and a power assembly 50. The support plate 20 and the base 10 are connected by the linkage assembly 30 and the transmission assembly 40. The power assembly 50 connects the transmission assembly 40 and the linkage assembly 30, so that the transmission assembly 40 drives the linkage assembly 30 to move, thereby causing the support plate 20 to lift and rotate relative to the base 10. The workpiece is mounted on the support plate 20 to lift and rotate with the support plate 20.

[0037] In some embodiments, the support plate 20 has a support surface 2101, which is located on the side of the support plate 20 facing away from the base 10. The workpiece is mounted on the support surface 2101 so that it can rise and fall with the support plate 20 and flip as the support plate 20 rotates.

[0038] In some embodiments, the base 10 includes a support platform 13, a buffer plate 11, and an adjustment assembly 14. The support platform 13 and the buffer plate 11 are spaced apart along the lifting direction of the support plate 20. The adjustment assembly 14 is connected between the support platform 13 and the buffer plate 11 and is used to adjust the height between the support platform 13 and the buffer plate 11.

[0039] In some embodiments, the adjusting assembly 14 includes a screw 141 and a nut 142. The screw 141 is connected to the support platform 13 and extends vertically in the Z direction. One end of the nut 142 is disposed on the buffer plate 11, and the nut 142 is threadedly connected to the screw 141. By driving the nut 142 to rotate relative to the screw 141, the nut 142 is raised or lowered relative to the screw 141, thereby causing the nut 142 to drive the buffer plate 11 to rise or fall relative to the support platform 13.

[0040] In some embodiments, there are four screws 141 and four nuts 142. The four screws 141 are located at the four corners of the support platform 13, and each screw 141 is threaded with a nut 142 to more stably connect the buffer plate 11 and the support platform 13.

[0041] In some implementations, a buffer 111 is connected to the buffer plate 11. A mating member 21 is connected to the support plate 20. The mating member 21 corresponds to the buffer 111. When the support plate 20 rotates toward the buffer plate 11, the mating member 21 abuts against the buffer 111, so that the downward impact force of the support plate 20 acts on the buffer 111. The abutment between the buffer 111 and the mating member 21 can reduce the impact force of the support plate 20 on the buffer plate 11, and prevent the support plate 20 from directly hitting the buffer plate 11, which could cause damage to the support plate 20, the buffer plate 11, or the workpiece.

[0042] In some embodiments, there are four buffers 111 and four mating members 21, with each mating member 21 abutting against one buffer 111. The four are located at the four corners of the buffer plate 11 to better prevent the bearing plate 20 from directly impacting the buffer plate 11.

[0043] In some embodiments, the base 10 further includes a side plate 12. The side plate 12 is located on one side of the buffer plate 11 and is fixedly connected to the support platform 13. The side plate 12 is provided with a guide groove 121.

[0044] The support plate 20 is also fixedly connected to a rib plate 22. The rib plate 22 is located on the side of the support plate 20 facing the base 10, and the rib plate 22 is used to connect the linkage assembly 30 to increase the distance between the support plate 20 and the base 10, so as to prevent the support plate 20 from colliding or interfering with the buffer plate 11.

[0045] The linkage component 30 is connected to the rib plate 22, and the linkage component 30 cooperates with the guide groove 121, so that the support plate 20 and the base 10 are connected through the linkage component 30 and the guide groove 121. The transmission component 40 is connected to the linkage component 30 and the power component 50 respectively, so that the power component 50 can drive the linkage component 30 to move along the guide groove 121 through the transmission component 40, so as to drive the support plate 20 to rise, fall and rotate relative to the buffer plate 11.

[0046] Therefore, when the transmission component 40 drives the linkage component 30 to move along the guide groove 121 via the same power component 50, the linkage component 30 can drive the support plate 20 to rise and rotate relative to the base 10. The workpiece mounted on the support plate 20 rises and falls with the rise and fall of the support plate 20, and flips with the rotation of the support plate 20. The same power component 50 can control both the rise and fall and the rotation of the support plate 20. Compared with using two power components 50 to control the rise and fall and the rotation of the support plate 20 respectively, the cost of one power component 50 is saved, making the structure of the lifting and flipping mechanism 100 more compact, with fewer circuits, and reducing the difficulty of assembling and debugging the lifting and flipping mechanism 100.

[0047] In some embodiments, the base 10 includes two side plates 12, which are fixedly connected to the support platform 13 at intervals along a first direction X. Each side plate 12 is provided with a guide groove 121. The linkage assembly 30 and the transmission assembly 40 are both disposed between the two side plates 12. Each end of the linkage assembly 30 is connected to a guide groove 121, so that the linkage assembly 30 can be more stably connected to the guide groove 121.

[0048] In some embodiments, the support plate 20 is connected to two ribs 22, which are fixedly connected to the support plate 20 at intervals along a first direction X, so that the support plate 20 and the ribs 22 can be connected relatively stably. Both ribs 22 are located between the two side plates 12, and both ribs 22 are connected to the linkage assembly 30, so that the support plate 20 and the linkage assembly 30 can be connected more stably.

[0049] In the illustrated embodiment, the lifting direction of the support plate 20 is parallel to the vertical direction Z. The first direction X is parallel to the horizontal direction. The first direction X is perpendicular to the lifting direction.

[0050] Please see Figure 2 In some embodiments, the guide groove 121 includes a straight groove 1211 and an arc-shaped groove 1212. The straight groove 1211 extends in the vertical direction Z to guide the linkage assembly 30 to move the support plate 20 up and down. The arc-shaped groove 1212 connects to the straight groove 1211. The arc-shaped groove 1212 is used to guide the linkage assembly 30 to rotate the support plate 20 relative to the base 10.

[0051] The arc-shaped groove 1212 extends towards the side opposite to the base 10. Therefore, during the ascent of the support plate 20, the linkage component 30 first rises along the straight groove 1211, then enters the arc-shaped groove 1212 and swings along it. That is, the support plate 20 first causes the workpiece to rise, and then causes it to flip towards the side opposite to the base 10. Conversely, during the descent of the support plate 20, the linkage component 30 first swings along the arc-shaped groove 1212, then enters the straight groove 1211 and descends along it. That is, the support plate 20 first causes the workpiece to flip towards the side opposite to the base 10, and then causes it to descend.

[0052] Please see Figure 3 In some embodiments, the linkage assembly 30 includes a first rotating shaft 31, a second rotating shaft 32, a first cam 321, and a second cam 322. Both the first rotating shaft 31 and the second rotating shaft 32 pass through the rib plate 22. The first rotating shaft 31 is rotatable relative to the rib plate 22. The second rotating shaft 32 is fixedly connected to the rib plate 22. Each end of the first rotating shaft 31 is rotatably connected to a first cam 321. Each end of the second rotating shaft 32 is rotatably connected to a second cam 322. The first cam 321 is rotatably disposed within the straight groove 1211 and moves up and down along the straight groove 1211. The second cam 322 is rotatably disposed within the guide groove 121. The second cam 322 can move up and down along the straight groove 1211 and also along the arcuate groove 1212, allowing the first rotating shaft 31 and the second rotating shaft 32 to move smoothly along the guide groove 121.

[0053] The transmission assembly 40 includes a drive shaft 41, a first crank 42, and a second crank 43. The drive shaft 41 is used to connect to the power assembly 50, enabling the power assembly 50 to drive the drive shaft 41 to rotate. The first crank 42 is rotatably connected to the second crank 43 and is fixedly connected to the drive shaft 41. The second crank 43 is rotatably connected to the second rotating shaft 32. When the drive shaft 41 rotates, the first crank 42 rotates around the drive shaft 41, driving the second crank 43 to push the second rotating shaft 32 up and down. The first rotating shaft 31 and the rib plate 22 rise and fall together until the first rotating shaft 31 moves to the top of the straight groove 1211. At this time, the second rotating shaft 32 drives the rib plate 22 and the bearing plate 20 to rotate around the first rotating shaft 31.

[0054] One end of the first crank 42 is fixedly connected to the drive shaft 41, and the other end of the first crank 42 is rotatably connected to one end of the second crank 43. The other end of the second crank 43 is rotatably connected to the second shaft 32. Please refer to [link / reference]. Figure 4 and Figure 5 When the drive shaft 41 drives one end of the first crank 42 to rotate, the other end of the first crank 42 pushes one end of the second crank 43 to rise and fall until the other end of the second crank 43 pushes the second rotating shaft 32, causing the second rotating shaft 32 to move along the guide groove 121.

[0055] The first rotating shaft 31, the second rotating shaft 32, and the transmission shaft 41 all extend along the first direction X. The first rotating shaft 31 and the second rotating shaft 32 are spaced apart by a preset distance, and the first rotating shaft 31 is located above the second rotating shaft 32 when the bearing plate 20 is parallel to the buffer plate 11.

[0056] Please see Figure 5 and Figure 6 When the second rotating shaft 32 is pushed to the end of the straight groove 1211, the first rotating shaft 31 and the second rotating shaft 32 are at the same height in the vertical direction Z. The second rotating shaft 32 moves around the first rotating shaft 31 along the arc groove 1212 with the first rotating shaft 31 as the center and a preset distance as the radius.

[0057] Please see Figure 1 In some embodiments, the power assembly 50 includes a power source 51, a drive pulley 52, a driven pulley 53, and a belt 54. The power source 51 is mounted on the side of the support platform 13 facing away from the buffer plate 11. The power source 51 is coaxially connected to the drive pulley 52. ​​The drive pulley 52 is coaxially connected to the drive shaft 41. The driven pulley 53 is coaxially connected to the drive shaft 41. The belt 54 is tensioned between the drive pulley 52 and the driven pulley 53. The power source 51 drives the drive pulley 52 to rotate, causing the belt 54 to drive the driven pulley 53 and the drive shaft 41 to rotate, thereby causing the first crank 42 and the second crank 43 to push the linkage assembly 30 along the guide groove 121.

[0058] Please see Figures 4 to 6 The support platform 13 is connected to a partition 131 on the side facing away from the buffer plate 11. There are four partitions 131, which are used to support the support platform 13.
