Description

Technical Field

[0001] This invention relates to the field of automated production equipment technology, and in particular to a turntable mechanism. Background Technology

[0002] In the field of automated production technology, turntables are commonly used for workpiece inspection or processing due to their advantages of multi-station operation and small footprint. When it is necessary to use a turntable mechanism to inspect or process both sides of a workpiece, a fixed component that holds the workpiece in place needs to be rotated at a fixed station.

[0003] However, the turntable is prone to vibration during rotation, which causes the fixed component to rotate along its own rotation axis as the turntable rotates. This results in an angle deviation when the fixed component reaches the workstation that needs to be flipped, making it impossible to flip or resulting in an incorrect angle after flipping, which affects the inspection or processing of the workpiece. Summary of the Invention

[0004] The purpose of this invention is to provide a turntable mechanism that ensures the rotating shaft does not rotate, thereby ensuring the stability of the fixed component during the rotation of the turntable.

[0008] A turntable is rotatably mounted on a fixed platform. The turntable is provided with a plurality of fixed components spaced apart along its circumference. The fixed components are rotatably connected to the turntable. Each fixed component includes a rotating shaft with an anti-rotation plane. When the fixed component rotates with the turntable, the anti-rotation plane slides against the anti-rotation ring.

[0009] A drive assembly configured to drive the shaft to rotate.

[0010] As an optional embodiment of the aforementioned turntable mechanism, the driving assembly includes a driving member rotatably mounted on the fixed platform. The driving member has a driving groove, and the rotating shaft can abut against the inner wall of the driving groove so that the driving member can drive the rotating shaft to rotate.

[0011] As an optional solution for the aforementioned turntable mechanism, the anti-rotation ring has an avoidance notch, and when the driving component drives the rotating shaft to rotate, the rotating shaft is located at the position of the avoidance notch.

[0012] As an optional embodiment of the aforementioned turntable mechanism, the driving component is axially telescopically mounted on the fixed platform; and / or

[0013] The drive groove extends to at least one end in a direction perpendicular to the rotation axis of the drive member and penetrates to the surface of the drive member.

[0014] As an optional solution for the aforementioned turntable mechanism, the anti-rotation ring is spaced apart from the fixed platform, and the anti-rotation plane slides against the side of the anti-rotation ring opposite to the turntable.

[0015] As an alternative to the aforementioned turntable mechanism, the fixed platform is provided with at least two drive components, and the at least two drive components are arranged at circumferential intervals along the fixed platform.

[0016] As an alternative to the aforementioned turntable mechanism, the rotating shaft has two anti-rotation planes, and the two anti-rotation planes are located on opposite sides of the radial direction of the rotating shaft.

[0017] As an optional solution for the aforementioned turntable mechanism, the turntable mechanism further includes a support assembly, which includes a support column and rollers. The support assembly is disposed below the turntable, the height of the support column is adjustable, and the rollers are rotatably disposed on the support column and roll against the turntable.

[0018] As an optional solution for the aforementioned turntable mechanism, the fixing component includes:

[0022] As an optional solution for the aforementioned turntable mechanism, the driving unit has a driving ramp. During the process of the cover plate closing onto the base, the driving ramp slides against the positioning slider and drives the positioning slider to abut against one side edge of the workpiece.

[0023] The beneficial effects of this invention are:

[0024] This invention provides a turntable mechanism. In this turntable mechanism, during the rotation of the turntable, the anti-rotation plane of the rotating shaft of the fixed component slides against the anti-rotation ring of the fixed platform.

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] In the field of automated production technology, turntables are commonly used for workpiece inspection or processing due to their advantages of multi-station operation and small footprint. When it is necessary to use a turntable mechanism to inspect or process both sides of a workpiece, a fixed component that holds the workpiece in place needs to be rotated at a fixed station.

[0045] However, the turntable is prone to vibration during rotation, which causes the fixed component to rotate along its own rotation axis as the turntable rotates. This results in an angle deviation when the fixed component reaches the workstation that needs to be flipped, making it impossible to flip or resulting in an incorrect angle after flipping, which affects the inspection or processing of the workpiece.

[0046] To address the aforementioned problems, this embodiment provides a turntable mechanism, such as... Figures 1-4 As shown, the turntable mechanism includes a fixed platform 1, a turntable 2, and a drive assembly 4. The fixed platform 1 is provided with an anti-rotation ring 11. The turntable 2 is rotatably mounted on the fixed platform 1. The turntable 2 is provided with multiple fixed assemblies 3 at intervals along the circumference. The fixed assemblies 3 are rotatably connected to the turntable 2. The fixed assemblies 3 include a rotating shaft 31. The rotating shaft 31 has an anti-rotation plane 311. When the fixed assemblies 3 rotate with the turntable 2, the anti-rotation plane 311 slides against the anti-rotation ring 11. The drive assembly 4 is configured to drive the rotating shaft 31 to rotate.

[0047] In this rotary table mechanism, the drive assembly 4 is fixedly mounted on the fixed platform 1. When the fixed assembly 3 rotates with the turntable 2 to the drive assembly 4, the drive assembly 4 can drive the fixed assembly 3 to rotate. During the rotation of the turntable 2, the anti-rotation plane 311 of the rotating shaft 31 of the fixed assembly 3 slides against the anti-rotation ring 11 of the fixed platform 1. The anti-rotation ring 11 ensures that the rotating shaft 31 will not rotate, thus ensuring the stability of the fixed assembly 3 during the rotation with the turntable 2. This allows the drive assembly 4 to flip the fixed assembly 3 to a suitable angle when it moves to a workstation that needs to be flipped, enabling the inspection and processing of the workpiece and improving efficiency.

[0048] In this embodiment, the workpiece is described using a packaging box 100 that requires labeling 101 as an example. The packaging box 100 is a sheet, and labels 101 need to be affixed to both its front and back sides. Therefore, the fixing component 3 needs to be flipped to facilitate labeling 101 onto the packaging box 100. The side facing upward when the packaging box 100 is placed into the fixing component 3 is called the front side, and the other side is called the back side.

[0049] like Figure 4 and Figure 5As shown, the fixing component 3 includes a base 32, a positioning structure 33, and a cover plate 34. The base 32 is fixedly connected to the rotating shaft 31. The base 32 has a positioning groove 321 for placing the packaging box 100. The positioning structure 33 includes a positioning slider 331, which is slidably disposed on the base 32. The cover plate 34 is slidably disposed on the base 32 and located above the base 32. The cover plate 34 has a driving part 341. During the process of the cover plate 34 closing onto the base 32 to press the packaging box 100 into the positioning groove 321, the driving part 341 can drive the positioning slider 331 to approach the packaging box 100 and abut against one side edge of the packaging box 100.

[0050] To facilitate the labeling 101 operation, the cover plate 34 and the base 32 are arranged in the vertical direction, and the packaging box 100 is placed horizontally in the positioning groove 321. When it is necessary to apply the label 101 to the back of the packaging box 100, it is only necessary to rotate the fixing component 3 180°.

[0051] The packaging box 100 is located in the positioning groove 321. As the cover plate 34 slides toward the base 32, the driving part 341 on the cover plate 34 can drive the positioning slider 331 to approach the packaging box 100 and abut against one edge of the packaging box 100, thereby positioning the packaging box 100. When the cover plate 34 closes to the base 32, it can press the packaging box 100 in the positioning groove 321 tightly, thereby ensuring that the packaging box 100 remains stable during the movement of the fixing component 3. Moreover, since the positioning process of the packaging box 100 does not require the operator to manually press the packaging box 100 to ensure its stability, there is no risk of the operator's hand being removed from the positioning groove 321, which would cause the packaging box 100 to move and affect its positional accuracy. This greatly improves the accuracy of the packaging box 100's position in the positioning groove 321, ensuring accuracy for the subsequent labeling 101 operation.

[0052] Understandably, to avoid affecting the labeling operation 101, both the base 32 and the cover 34 are provided with clearance structures, and these clearance structures correspond to the positions on the packaging box 100 where the label 101 needs to be applied, so as to ensure that the labeling operation 101 can be completed without opening the cover 34 and the base 32. In this embodiment, the clearance structure can be a clearance groove or a clearance hole.

[0053] In this embodiment, the fixing component 3 includes two positioning structures 33. The sliding directions of the positioning sliders 331 of the two positioning structures 33 are set at an angle. That is, the two positioning sliders 331 can position the packaging box 100 in different directions to ensure the accuracy of the position of the packaging box 100 in the positioning groove 321.

[0054] like Figure 5 and Figure 6As shown, the drive unit 341 has a drive ramp 3411. During the process of the cover plate 34 closing on the base 32, the drive ramp 3411 slides against the positioning slider 331 and drives the positioning slider 331 to abut against one side edge of the packaging box 100.

[0055] In this embodiment, when the cover plate 34 is above the base 32, the driving inclined surface 3411 is inclined in the direction away from the packaging box 100 in the downward direction. This arrangement enables the driving part 341 to move downward, and the contact portion between the driving inclined surface 3411 and the positioning slider 331 is close to the packaging box 100 in the horizontal direction, that is, the driving positioning slider 331 is close to the packaging box 100.

[0056] In this embodiment, the positioning structure 33 further includes a fixed seat 332, which is fixedly connected to the base 32. The positioning slider 331 is slidably disposed on the fixed seat 332. A first elastic element is disposed between the positioning slider 331 and the fixed seat 332. The first elastic element is configured to drive the positioning slider 331 to move away from the packaging box 100. The first elastic element facilitates the insertion of the packaging box 100 into the positioning groove 321 or the removal of the packaging box 100 from the positioning groove 321 when the cover plate 34 is not engaged with the base 32.

[0057] Furthermore, the fixed base 332 is provided with a limiting block 333. When the positioning slider 331 moves away from the packaging box 100, it can abut against the limiting block 333 and be limited by the limiting block 333. The limiting block 333 can prevent the positioning slider 331 from disengaging from the fixed base 332 under the drive of the first elastic element, and can also ensure that when the cover plate 34 is fastened to the base 32, the driving inclined surface 3411 can abut against the positioning slider 331 to drive the positioning slider 331 closer to the packaging box 100.

[0058] It is worth noting that, in order to achieve the above purpose, when the positioning slider 331 abuts against the limiting block 333, at least part of the positioning slider 331 is located within the range of the driving inclined surface 3411 in the vertical direction.

[0059] In this embodiment, the positioning slider 331 has a driven inclined surface 3311. During the process of the cover plate 34 being fastened to the base 32, the driven inclined surface 3311 of the positioning slider 331 slides and abuts against the driving inclined surface 3411 of the driving part 341 to prevent the sharp corner structure from scratching the driving inclined surface 3411. Specifically, the inclination direction and slope of the driven inclined surface 3311 are the same as those of the driving inclined surface 3411.

[0060] In this embodiment, the driving unit 341 further includes a retaining surface 3412, which is connected to the driving inclined surface 3411 and is arranged in the vertical direction. After the positioning slider 331 slides along the driving inclined surface 3411, it slides and abuts against the retaining surface 3412. The arrangement of the retaining surface 3412 ensures that the positioning slider 331 no longer moves in the horizontal direction when the cover plate 34 is not fully engaged with the base 32, thus completing the positioning of the packaging box 100. At this time, the cover plate 34 can continue to approach the base 32 and engage with the base 32.

[0061] In this embodiment, the fixing component 3 further includes a guide post 35 and a limiting member 36. One end of the guide post 35 is fixedly connected to the cover plate 34, and the other end of the guide post 35 passes through the base 32 and is fixedly connected to the limiting member 36. The guide post 35 can provide guidance for the relative movement between the cover plate 34 and the base 32, ensuring that the cover plate 34 can accurately close to the base 32. The limiting member 36 can prevent the guide post 35 from detaching from the base 32, ensuring that the cover plate 34 and the base 32 will not separate. It can also serve as a structure to drive the cover plate 34 to move. The closing and opening of the cover plate 34 and the base 32 can be controlled by using a linear drive structure such as a drive cylinder to drive the limiting member 36.

[0062] Furthermore, the fixing component 3 also includes a second elastic element 37, which is disposed between the limiting member 36 and the base 32. The second elastic element 37 is configured to drive the limiting member 36 away from the base 32. The second elastic element 37 enables the cover 34 to close onto the base 32 and provides a certain holding force, so that the cover 34 and the base 32 will not open when moved or flipped, ensuring the stability of the packaging box 100.

[0063] like Figure 3 and Figure 7 As shown, the drive assembly 4 includes a drive member 41, which is rotatably mounted on the fixed platform 1. The drive member 41 has a drive groove 411, and the rotating shaft 31 can abut against the inner wall of the drive groove 411 so that the drive member 41 can drive the rotating shaft 31 to rotate. When the fixed assembly 3 rotates with the turntable 2 to the drive assembly 4, the rotating shaft 31 is engaged in the drive groove 411, and the rotating shaft 31 can abut against the inner wall of the drive groove 411. At this time, the drive member 41 can drive the rotating shaft 31 to rotate, completing the flipping of the fixed assembly 3.

[0064] In this embodiment, the inner wall of the drive groove 411 abuts against the anti-rotation plane 311, and the rotating shaft 31 is driven to rotate through the anti-rotation plane 311. The structure is simple and does not add any additional structure or cost.

[0065] In this embodiment, the rotating shaft 31 has two anti-rotation planes 311, and the two anti-rotation planes 311 are located on opposite sides of the radial direction of the rotating shaft 31. The two anti-rotation planes 311 can ensure that the fixing component 3 can still be stabilized by the anti-rotation ring 11 after being flipped.

[0066] Since the rotating shaft 31 has two anti-rotation planes 311, when the rotating shaft 31 is inserted into the drive groove 411, the inner wall of the drive groove 411 simultaneously abuts against the two anti-rotation planes 311, which can further improve the synchronization of rotation between the rotating shaft 31 and the drive component 41, and avoid the relative sliding between the rotating shaft 31 and the drive groove 411 from affecting the synchronization of the rotating shaft 31 and the drive component 41.

[0067] In this embodiment, the rotating shaft 31 is a quadrangular prism, and two opposite sides of the quadrangular prism form two anti-rotation planes 311. The quadrangular prism can also be fixedly connected to the base 32 without relative rotation, ensuring the accuracy of the angle when the fixing component 3 is flipped. In some embodiments, the rotating shaft 31 can also be a cylinder, with two anti-rotation planes 311 symmetrically machined on the sidewalls of the cylinder, which can also cooperate with the drive groove 411 and be driven by the drive component 41.

[0068] In this embodiment, the drive member 41 is axially extendable and retractable on the fixed platform 1. When the fixed component 3 moves to the position of the drive component 4, the drive member 41 extends out until the rotating shaft 31 is inserted into the drive groove 411, at which time the drive member 41 can drive the rotating shaft 31 to rotate.

[0069] Specifically, the drive assembly 4 includes a telescopic cylinder 42 and a rotary cylinder 43. The telescopic cylinder 42 is fixedly mounted on the fixed platform 1. The rotary cylinder 43 is connected to the piston rod of the telescopic cylinder 42. The drive component 41 is connected to the piston rod of the rotary cylinder 43. The telescopic cylinder 42 and the rotary cylinder 43 can complete the telescopic and rotary movements of the drive component 41.

[0070] In some embodiments, the drive groove 411 extends to at least one end along a direction perpendicular to the rotation axis of the drive member 41 and penetrates the surface of the drive member 41. At this time, the opening of the drive groove 411 on the surface of the drive member 41 is located on the rotation path of the fixing component 3. When the fixing component 3 rotates to the position of the drive component 4, the rotating shaft 31 will enter the drive groove 411 through one of the openings. After the drive member 41 drives the rotating shaft 31 to rotate, the rotating shaft 31 will move out of the drive groove 411 again through the opening.

[0071] It is understandable that, because the anti-rotation plane 311 slides against the anti-rotation ring 11, when the drive member 41 rotates the shaft 31, the shaft 31 and the drive member 41 will interfere with the anti-rotation ring 11. Figure 3As shown, to solve the above problem, the anti-rotation ring 11 has a clearance notch 111. When the drive member 41 drives the rotating shaft 31 to rotate, the rotating shaft 31 is located at the clearance notch 111. Since the clearance notch 111 is small and the turntable 2 has already decelerated to a stop when the rotating shaft 31 moves to the clearance notch 111, the fixing component 3 will not rotate on its own. Therefore, interference between the rotating shaft 31 and the drive member 41 and the anti-rotation ring 11 can be avoided when the drive member 41 drives the rotating shaft 31.

[0072] In this embodiment, the anti-rotation ring 11 is spaced apart from the fixed platform 1, and the anti-rotation plane 311 slides against the side of the anti-rotation ring 11 away from the turntable 2. This structure ensures that there is a certain gap between the rotating shaft 31 and the fixed platform 1, so that the driving component 41 will not contact the fixed platform 1 when it is sleeved outside the rotating shaft 31, thus facilitating the rotation of the rotating shaft 31.

[0073] Normally, after the fixing component 3 receives and fixes the packaging box 100, it needs to perform the labeling 101 operation on the packaging box 100. After the multiple processes at the rotating mechanism are completed, the packaging box 100 needs to be unloaded in the same state as when it was loaded. To achieve the above purpose, the fixing table 1 is provided with at least two drive components 4, and the at least two drive components 4 are arranged at intervals along the circumference of the fixing table 1.

[0074] The drive assembly 4 located upstream in the rotation direction of the turntable 2 is used to flip the fixing assembly 3 to affix the label 101 to the back of the packaging box 100, and the drive assembly 4 located downstream in the rotation direction of the turntable 2 is used to flip the front of the packaging box 100 back to face upwards, thereby facilitating the subsequent unloading operation of the packaging box 100.

[0075] like Figure 2 As shown, to ensure the stability of the turntable 2 during rotation, the turntable mechanism also includes a support assembly 5. The support assembly 5 includes a support column 51 and rollers 52. The support assembly 5 is located below the turntable 2. The height of the support column 51 is adjustable, and the rollers 52 are rotatably mounted on the support column 51 and roll against the turntable 2. By adjusting the height of the support column 51, the rollers 52 abut against the bottom surface of the turntable 2. During the rotation of the turntable 2, the rollers 52 always provide support, ensuring the stability of the turntable 2 during rotation.

[0076] Furthermore, the turntable mechanism includes multiple sets of support components 5, which are spaced apart circumferentially along the turntable 2. These multiple sets of support components 5 can support the turntable 2 from multiple positions, ensuring uniformity of support force while reducing the pressure on each set of support components 5, thus improving the stability of the turntable 2 and extending the service life of the support components 5.

[0077] To enable the turntable 2 to rotate, the turntable mechanism also includes a rotation drive 6, which is located below the turntable 2 and is used to drive the turntable 2 to rotate. Furthermore, the rotation drive 6 is a rotary motor. To reduce the rotational speed of the turntable 2 and ensure stability, the turntable mechanism also includes a reducer 7, which is connected to the rotation drive 6 in a transmission connection, and the reducer 7 is also connected to the turntable 2 in a transmission connection.

[0078] like Figure 1 and Figure 8 As shown, the turntable mechanism also includes a locking component 8, which includes a locking frame 82 and a locking element 81. The locking frame 82 is fixedly mounted on the fixed platform 1. The fixed component 3 includes a support, and the rotating shaft 31 is rotatably mounted on the support. The support is fixedly mounted on the turntable 2. The support has a locking hole, and the locking element 81 can be sequentially inserted into the locking frame 82 and the locking hole to lock the fixed component 3 and the turntable 2.

[0079] Specifically, the locking member 81 is a rod, and a limiting rod 83 is connected to the upper end of the locking member 81. After the locking member 81 passes through the locking frame 82, the limiting rod 83 abuts against the locking frame 82. The limiting rod 83 can limit the locking member 81, ensuring that the locking member 81 can be inserted into the locking hole without abutting against the turntable 2. Moreover, if the limiting rod 83 abuts against the locking frame 82, it also indicates that the locking member 81 is in the correct depth in the locking hole, ensuring the locking effect.

[0080] Furthermore, the locking assembly 8 also includes a sensor 84, which is disposed on the locking frame 82 and is used to sense the locking member 81. Specifically, when the sensor 84 senses the locking member 81, it indicates that the locking member 81 has been locked, and the turntable 2 cannot rotate at this time; when the sensor 84 cannot sense the locking member 81, it indicates that the locking member 81 has been removed, and the turntable 2 can be started at this time.

[0081] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
