[0017] The rotating scanning device of this application has the following advantages:
[0018] In the rotary scanning device of this application, the scanning component is used to scan the object to be scanned. Since the first sliding member is slidably connected to the arc-shaped guide member and slides relative to the arc-shaped guide member in a second direction, and the scanning component is fixedly connected to the first sliding member, when the first sliding member slides relative to the arc-shaped guide member in the second direction, it can drive the scanning component to swing in the second direction, thereby achieving rotary scanning of the scanning component and increasing the scanning range of the scanning component. During the swinging process of the scanning component in the second direction, the movement of the scanning component can be decomposed into a component movement along the first direction and a component movement along the radial direction of the arc-shaped guide member. Since the first linear module can drive the second sliding member of the second guide member to move along the first direction, and the scanning component is fixedly connected to the linear guide member of the second guide member, when the first linear module drives the second sliding member to move along the first direction, the second guide member has a force that drives the scanning component to move along the first direction. Since the second sliding member slides radially relative to the linear guide member along the arc-shaped guide member, the force that drives the scanning component to move along the first direction is ultimately transmitted to the second sliding member. At this point, the second slider drives the scanning assembly to move along the first direction. Under the action of the arc-shaped guide rail of the arc-shaped guide, the second slider eventually drives the scanning assembly to rotate along the arc-shaped guide. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] Reference Figure 1 as well as Figure 2 As shown, the rotating scanning device involved in the embodiments of this application has a first direction x and a second direction y, the first direction x and the second direction y are perpendicular to each other, and the rotating scanning device includes: a scanning component 100, a first guide component 200, a first linear module 300 and a second guide component 400.
[0042] Specifically, the first guide assembly 200 includes a first slider 210 and an arc-shaped guide 220. The arc-shaped guide 220 extends about a second direction y, and the first slider 210 is slidably connected to the arc-shaped guide 220. The first slider 210 rotates relative to the arc-shaped guide 220 about the second direction y. The scanning assembly 100 is fixedly connected to the first slider 210. When the first slider 210 rotates along the arc-shaped guide 220, the first slider 210 drives the scanning assembly 100 to rotate, thereby realizing rotational scanning.
[0043] The second guide assembly 400 includes a second slider 410 and a linear guide 420. The second slider 410 is connected to the first linear module 300, which drives the second slider 410 to move along a first direction x, and the second slider 410 rotates relative to the first linear module 300 about a second direction y. The linear guide 420 extends radially along the arcuate guide 220. The linear guide 420 is fixedly connected to the scanning assembly 100, and the second slider 410 is slidably connected to the linear guide 420 and slides radially relative to the linear guide 420 along the arcuate guide 220.
[0044] It should be noted that the first direction x is Figure 1 The direction indicated by x in the middle, and the second direction y is... Figure 1 The direction indicated by y in the middle.
[0045] It should be noted that in rotary scanning devices, the scanning component 100 is typically quite heavy. When the scanning component 100 moves on the arc-shaped guide 220, it usually undergoes an arc-shaped deflection movement on the guide 220. Due to the arc-shaped characteristics of the guide 220 and the weight of the scanning component 100, in conventional rotary scanning devices, a retainer is usually provided between the arc-shaped guide 220 and the scanning component 100 to ensure that the scanning component 100 can be stably maintained in a predetermined position during movement, avoiding displacement or detachment due to inertia.
[0046] However, as the inertia of the scanning component 100 increases and the number of swings increases, the retainer is usually affected by the movement of the scanning component 100, causing the retainer to detach from the arc guide 220 and the scanning component 100. This results in a decrease in the motion stability of the scanning component 100 on the arc guide 220, and at the same time, a decrease in the swing accuracy of the scanning component 100.
[0047] In the rotary scanning device of this application, the scanning component 100 is used to scan the object to be scanned. Since the first slider 210 is slidably connected to the arc-shaped guide 220 and slides relative to the arc-shaped guide 220 around the second direction y, and the scanning component 100 is fixedly connected to the first slider 210, when the first slider 210 slides relative to the arc-shaped guide 220 around the second direction y, the scanning component 100 can be driven to swing around the second direction y, thereby achieving rotary scanning of the scanning component 100 and increasing the scanning range of the scanning component 100.
[0048] During the swing of the scanning component 100 around the second direction y, the movement of the scanning component 100 can be decomposed into a component movement along the first direction x and a component movement along the radial direction of the arc-shaped guide 220. Since the first linear module 300 can drive the second slider 410 of the second guide component 400 to move along the first direction x, and the scanning component 100 is fixedly connected to the linear guide 420 of the second guide component 400.
[0049] Thus, when the first linear module 300 drives the second slider 410 to move along the first direction x, the second guide assembly 400 has a force that drives the scanning assembly 100 to move along the first direction x. Since the second slider 410 slides radially relative to the linear guide 420 along the arc guide 220, under the action of the arc guide rail of the arc guide 220, the second slider 410 ultimately drives the scanning assembly 100 to rotate along the arc guide 220.
[0050] Reference Figure 2 as well as Figure 3 As shown, the first guide component 200 further includes a connecting frame 230. The connecting frame 230 is symmetrically arranged on both sides of the central axis extending along the first direction x. The scanning component 100 is slidably connected to a first slider 210 on both sides along the second direction y.
[0051] In this embodiment, the first guide component 200 can be disposed on the connecting frame 230 to improve the structural stability of the first guide component 200. Furthermore, since the first guide components 200 are symmetrically disposed on both sides of the central axis extending along the first direction x of the connecting frame 230, the scanning component 100 is connected to a first sliding member 210 on both sides along the second direction y. Thus, the scanning component 100 can be connected to the middle position of the connecting frame 230 along the second direction y, and both ends of the scanning component 100 along the second direction y can be connected to the connecting frame 230, thereby improving the structural stability of the scanning component 100 when rotating around the second direction y and reducing the possibility of the scanning component 100 tipping over during rotation. Simultaneously, the first guide components 200 at both ends of the scanning component 100 along the second direction y improve the directional accuracy of the scanning component 100's rotation around the second direction y, ensuring that the scanning component 100 always rotates around the second direction y.
[0052] Specifically, refer to Figure 2 as well as Figure 3 As shown, in this embodiment, the connecting frame 230 is provided with a receiving space 232. In the first direction x, the central axis of the receiving space 232 coincides with the central axis of the connecting frame 230. The receiving space 232 is symmetrically provided with first guide components 200 on both sides along the second direction y. The scanning component 100 is disposed in the receiving space 232, and the scanning component 100 is connected to a first sliding member 210 on both sides along the second direction y. In this way, the connecting frame 230 can be arranged around the scanning component 100 to place the scanning component 100 at the center position of the connecting frame 230, thereby improving the stabilizing effect of the connecting frame 230 on the scanning component 100 and improving the structural stability of the scanning component 100 when rotating around the second direction y.
[0053] Reference Figure 2 As shown, the first linear module 300 is connected to the connecting frame 230 and is disposed on one side of the scanning assembly 100 along the second direction y. The first linear module 300 includes a first driving member 310, a first lead screw 320, and a first moving member 330. The drive shaft of the first driving member 310 is fixedly connected to the first lead screw 320, the first lead screw 320 extends along the first direction x, and the first lead screw 320 is threadedly connected to the first moving member 330, thereby driving the first moving member 330 to move along the first direction x.
[0054] In this embodiment, the first linear module 300 can be mounted on the connecting frame 230 to improve the structural stability of the first linear module 300. Since the first driving member 310 is connected to the first lead screw 320 and is used to drive the first lead screw 320 to rotate around the first direction x, and the first lead screw 320 extends along the first direction x and is threadedly connected to the first moving member 330, when the first driving member 310 drives the first lead screw 320 to rotate around the first direction x, the first moving member 330 can move along the first direction x on the first lead screw 320, so that the scanning component 100 can be driven to move along the first direction x on the arc-shaped guide member 220 through the first moving member 330, so as to realize the partial movement of the scanning component 100 along the first direction x on the arc-shaped guide member 220.
[0055] Reference Figure 4 As shown, the first linear module 300 also includes a first sensor 340, a second sensor 350, and a third sensor 360. The first sensor 340, the second sensor 350, and the third sensor 360 are all disposed on one side of the first lead screw 320 along the second direction y and are spaced apart along the first direction x. The first sensor 340 is disposed between the second sensor 350 and the third sensor 360. The first sensor 340 is disposed at a first preset position, the second sensor 350 is disposed at a second preset position, and the third sensor 360 is disposed at a third preset position.
[0056] Specifically, in this embodiment, when the first moving member 330 moves along the first direction x to the first preset position, the scanning component 100 is located at the middle position of the arc-shaped guide 220 along the first direction x, that is, the scanning component 100 is at the origin position before the swing. When the first moving member 330 moves along the first direction x to the second preset position, the scanning component 100 is located at one end edge of the arc-shaped guide 220 along the first direction x, that is, the scanning component 100 is at one of the extreme positions after the swing. When the first moving member 330 moves along the first direction x to the third preset position, the scanning component 100 is located at the other end edge of the arc-shaped guide 220 along the first direction x, that is, the scanning component 100 is at another extreme position after the swing.
[0057] In this embodiment, the first sensor 340, the second sensor 350, and the third sensor 360 can all detect the position of the first moving member 330. When the first moving member 330 moves along the first direction x to the first preset position, the first moving member 330 can be detected by the first sensor 340, indicating that the scanning component 100 is currently at the middle position of the arc guide 220 along the first direction x, that is, the scanning component 100 is at the origin position before the swing; when the first moving member 330 moves along the first direction x to the second preset position, the first moving member 330 can detect the position of the first moving member 330. The first moving member 330 can be detected by the second sensor 350 to indicate that the scanning component 100 is currently swinging to one end edge of the arc guide 220 along the first direction x, that is, the scanning component 100 is at one of the extreme positions after swinging; when the first moving member 330 moves to the third preset position along the first direction x, the first moving member 330 can be detected by the third sensor 360 to indicate that the scanning component 100 is currently swinging to the other end edge of the arc guide 220 along the first direction x, that is, the scanning component 100 is at another extreme position after swinging.
[0058] Specifically, in this embodiment, the rotary scanning device of this application further includes a control system (not shown). The first drive member 310, the first sensor 340, the second sensor 350, and the third sensor 360 are all electrically connected to the control system. When the first moving member 330 moves to the first preset position, the first moving member 330 can be detected by the first sensor 340. The first sensor 340 sends a signal to the control system to prompt the operator that the scanning component 100 is currently at the origin position before swinging. When the first moving member 330 moves along the first direction x to the second preset position, the first moving member 330 can be detected by the second sensor 350. The second sensor 350 sends a signal to the control system. At this time, the control system sends an alarm signal based on the signal to warn the operator that the scanning component 100 has swung to one of the positions of the arc guide member 220 along the first direction x. At the extreme position, that is, when the scanning component 100 is at one of the extreme positions after swinging, the control system will control the first drive component 310 to stop, so that the first moving component 330 stops moving along the first direction x, thereby avoiding excessive swinging of the scanning component 100. When the first moving component 330 moves along the first direction x to the third preset position, the first moving component 330 can be detected by the third sensor 360. The third sensor 360 sends a signal to the control system. At this time, the control system sends an alarm signal to the operator to warn that the scanning component 100 has swung to one of the extreme positions of the arc guide 220 along the first direction x, that is, the scanning component 100 is at another extreme position after swinging. At the same time, the control system will control the first drive component 310 to stop, so that the first moving component 330 stops moving along the first direction x, thereby avoiding excessive swinging of the scanning component 100.
[0059] Specifically, refer to Figure 4 As shown, in this embodiment, the first sensor 340 is a first photoelectric sensor, the second sensor 350 is a second photoelectric sensor, and the third sensor 360 is a third photoelectric sensor. The first moving member 330 has a first detection unit 331. When the first moving member 330 moves along the first direction x, the first detection unit 331 will pass between the transmitting end and receiving end of the first photoelectric sensor, the second photoelectric sensor, and the third photoelectric sensor in sequence. When the first detection unit 331 passes through each photoelectric sensor, the receiving end of the photoelectric sensor will not detect the light signal due to the blockage of the first detection unit 331, thereby triggering the output signal to realize the detection function of the first moving member 330.
[0060] Continue to refer to Figure 4As shown, the first linear module 300 also includes a first limiting member 370 and a second limiting member 380. The first limiting member 370 and the second limiting member 380 are both disposed on one side of the first lead screw 320 along the second direction y and are spaced apart along the first direction x. The first sensor 340, the second sensor 350 and the third sensor 360 are all disposed between the first limiting member 370 and the second limiting member 380.
[0061] Specifically, in this embodiment, the first limiting member 370 is positioned close to the second sensor 350, and the second limiting member 380 is positioned close to the third sensor 360.
[0062] In this embodiment, when the first moving member 330 moves along the first direction x to the second sensor 350 or the third sensor 360, and the sensor at that position does not trigger a signal, the control system will not control the first driving member 310 to stop. The first moving member 330 will continue to move along the first direction x. Since the first sensor 340, the second sensor 350 and the third sensor 360 are all located between the first limiting member 370 and the second limiting member 380, the first moving member 330, which continues to move along the first direction x, will abut against the first limiting member 370 or the second limiting member 380. The first limiting member 370 or the second limiting member 380 will mechanically and hard limit the first moving member 330, thereby preventing the first moving member 330 from moving excessively along the first direction x, and further preventing the scanning component 100 from swinging excessively around the second direction y.
[0063] Specifically, in this embodiment, the rotary scanning device further includes a first encoder (not shown), which is connected to the second slider 410 to detect the moving distance and moving speed of the second slider 410 along the first direction x, so as to precisely control the swing of the scanning component 100 around the second direction y.
[0064] Reference Figure 1 as well as Figure 5 As shown, the rotary scanning device also includes a rotary assembly 500, which includes a second drive member 510 and a transmission shaft 520. The transmission shaft 520 is fixedly connected to the connecting frame 230, and the second drive member 510 is used to drive the transmission shaft 520 to rotate around the first direction x.
[0065] In this embodiment, since the drive shaft 520 is connected to the connecting frame 230, and the second drive member 510 is used to drive the drive shaft 520 to rotate around the first direction x, when the second drive member 510 drives the drive shaft 520 to rotate around the first direction x, the connecting frame 230 can be driven to rotate around the first direction x through the drive shaft 520, so as to drive the scanning component 100 to rotate around the first direction x through the connecting frame 230. In this way, the scanning component 100 can be rotated around both the first direction x and the second direction y, thereby improving the ability of the scanning component 100 to meet the requirements of omnidirectional scanning in complex scenarios.
[0066] Reference Figure 5 As shown, the scanning assembly 100 includes a scanning element 110, which is connected to the connecting frame 230, and the central axis of the scanning element 110 intersects the rotation axis of the drive shaft 520.
[0067] In this embodiment, since the central axis of the scanning element 110 intersects the rotation axis of the transmission shaft 520, the swing axis of the scanning element 110 about the second direction y intersects the rotation axis of the scanning element 110 about the first direction x, so that the rotary scanning device of this application can scan small-sized objects, thereby improving the scanning accuracy.
[0068] Reference Figure 3 as well as Figure 6 As shown, the rotating scanning device also has a third direction z, which is perpendicular to the first direction x and the second direction y. The rotating assembly 500 also includes a rotating connecting seat 530, which is connected to the drive shaft 520. The connecting frame 230 is connected to the rotating connecting seat 530. The rotating assembly 500 also includes a first connecting member 540 and a second connecting member 550. The rotating connecting seat 530 and / or the connecting frame 230 are provided with a first connecting groove 231 extending along the second direction y. The first connecting member 540 passes through the first connecting groove 231 and is connected to the rotating connecting seat 530 and the connecting frame 230. The rotating connecting seat 530 and / or the connecting frame 230 are provided with a second connecting groove 531 extending along the third direction z. The second connecting member 550 passes through the second connecting groove 531 and is connected to the rotating connecting seat 530 and the connecting frame 230.
[0069] It should be noted that the third party is z. Figure 1 The direction indicated by z in the middle.
[0070] Specifically, in some embodiments, the connecting frame 230 is provided with a first connecting groove 231 extending along the second direction y, and the rotating connecting seat 530 is provided with a second connecting groove 531 extending along the third direction z; in some embodiments, the rotating connecting seat 530 is provided with a first connecting groove 231 extending along the second direction y and a second connecting groove 531 extending along the third direction z; in some embodiments, the connecting frame 230 is provided with a first connecting groove 231 extending along the second direction y and a second connecting groove 531 extending along the third direction z; in some embodiments, the rotating connecting seat 530 and the connecting frame 230 are provided with a first connecting groove 231 extending along the second direction y, and the rotating connecting seat 530 and the connecting frame 230 are provided with a second connecting groove 531 extending along the third direction z.
[0071] In this embodiment, since the first connector 540 is connected to the rotary connector 530 and the connecting frame 230, the rotary connector 530 and the connecting frame 230 can be connected through the first connector 540. Furthermore, since the first connector 540 passes through the first connecting groove 231, and the first connecting groove 231 extends along the second direction y, the relative position of the connecting frame 230 and the rotary connector 530 in the second direction y can be fine-tuned by adjusting the position of the first connector 540 within the first connecting groove 231. This fine-tunes the position of the central axis of the scanning element 110 in the second direction y, thereby improving the positioning accuracy of the scanning element 110 in the second direction y and ensuring the positioning accuracy of the scanning element 110. The central axis of 10 can intersect with the rotation axis of the drive shaft 520. Since the second connector 550 is connected to the rotary connector 530 and the connecting frame 230, the rotary connector 530 and the connecting frame 230 can be connected through the second connector 550 to improve the connection stability between the rotary connector 530 and the connecting frame 230. Since the second connector 550 passes through the second connecting groove 531 and the second connecting groove 531 extends along the third direction z, the position of the scanning element 110 in the third direction z can be finely adjusted by adjusting the position of the second connector 550 in the second connecting groove 531 to improve the positioning accuracy of the scanning element 110 in the third direction z.
[0072] Reference Figure 7As shown, in this embodiment, the rotary scanning device further includes a frame 600 and a second linear module 700. The second linear module 700 includes a rotary handle 710, a second lead screw 720, and a second moving member 730. The second lead screw 720 is connected to the frame 600 and extends along a third direction z. One end of the second lead screw 720 along the third direction z is connected to the rotary handle 710. The second moving member 730 is threadedly connected to the second lead screw 720. The rotary assembly 500 is connected to the second moving member 730. Before scanning the workpiece 110, the second lead screw 720 can be moved by rotating the rotary handle 710. The lever 720 rotates relative to the frame 600 about a third direction z, so that the second moving member 730 moves along the third direction z on the second lead screw 720. The second moving member 730 drives the rotating component 500 to move along the third direction z, which in turn drives the scanning component 100 to move along the third direction z, so that the scanning component 100 moves to the scanning position. Then, the positions of the first connecting member 540 and the second connecting member 550 in the second connecting groove 531 are adjusted to fine-tune the position of the scanning component 100 and improve the positional accuracy of the scanning component 100.
[0073] Reference Figure 5 As shown, the rotating assembly 500 also includes a fourth sensor 560, a fifth sensor 570, and a sixth sensor 580. The fourth sensor 560, the fifth sensor 570, and the sixth sensor 580 are all radially spaced from the rotating connecting seat 530 and circumferentially spaced from it. The fourth sensor 560 is located between the fifth sensor 570 and the sixth sensor 580. The fourth sensor 560 is located at a fourth preset position, the fifth sensor 570 is located at a fifth preset position, and the sixth sensor 580 is located at a sixth preset position.
[0074] Specifically, in this embodiment, when the preset part of the rotating connecting seat 530 rotates around the first direction x to the fourth preset position, the central axis of the scanning element 110 extends along the third direction z, that is, the scanning element 110 is at the origin position before rotation. When the preset part of the rotating connecting seat 530 rotates around the first direction x to the fifth preset position, the rotating connecting seat 530 rotates to one of the extreme positions. When the preset part of the rotating connecting seat 530 rotates around the first direction x to the sixth preset position, the rotating connecting seat 530 rotates to another extreme position.
[0075] In this embodiment, the fourth sensor 560, the fifth sensor 570, and the sixth sensor 580 are all used to detect preset positions of the rotating connector 530. When the preset position of the rotating connector 530 rotates around the first direction x to the fourth preset position, the preset position of the rotating connector 530 can be detected by the fourth sensor 560, indicating that the scanning element 110 is currently at the origin position before rotation. When the preset position of the rotating connector 530 rotates around the first direction x to the fifth preset position, the preset position of the rotating connector 530 can be detected by the fifth sensor 570, indicating that the scanning element 110 has rotated around the first direction x to one of the extreme positions. When the preset position of the rotating connector 530 rotates around the first direction x to the sixth preset position, the preset position of the rotating connector 530 can be detected by the sixth sensor 580, indicating that the scanning element 110 has rotated around the first direction x to another extreme position.
[0076] Specifically, in this embodiment, the second driving component 510, the fourth sensor 560, the fifth sensor 570, and the sixth sensor 580 are all electrically connected to the control system. When the preset part of the rotating connecting seat 530 rotates around the first direction x to the fourth preset position, the preset part of the rotating connecting seat 530 can be detected by the fourth sensor 560, and a signal is sent to the control system to prompt the operator that the scanning component 110 is currently at its original position before rotation. When the preset part of the rotating connecting seat 530 rotates around the first direction x to the fifth preset position, the preset part of the rotating connecting seat 530 can be detected by the fifth sensor 570, and the fifth sensor 570 sends a signal to the control system. At this time, the control system sends an alarm signal based on the signal to warn the operator. When the scanning element 110 has rotated to one of its extreme positions around the first direction x, the control system will control the second drive element 510 to stop, so that the rotating connecting seat 530 stops rotating around the first direction x, thereby preventing the scanning element 110 from rotating excessively. When the preset part of the rotating connecting seat 530 rotates to the sixth preset position around the first direction x, the preset part of the rotating connecting seat 530 can be detected by the sixth sensor 580 and send a signal to the control system. At this time, the control system sends an alarm signal to the operator to warn that the scanning element 110 has rotated to another extreme position around the first direction x. At the same time, the control system will control the second drive element 510 to stop, so that the rotating connecting seat 530 stops rotating around the first direction x, thereby preventing the scanning element 110 from rotating excessively.
[0077] Specifically, refer to Figure 5As shown, in this embodiment, the fourth sensor 560 is the fourth photoelectric sensor, the fifth sensor 570 is the fifth photoelectric sensor, and the sixth sensor 580 is the sixth photoelectric sensor. The rotating connecting seat 530 has a second detection unit 532, which is a preset part of the rotating connecting seat 530. When the rotating connecting seat 530 moves around the first direction x, the second detection unit 532 will pass between the transmitting end and receiving end of the fourth photoelectric sensor, the fifth photoelectric sensor, and the sixth photoelectric sensor in sequence. When the second detection unit 532 passes through each photoelectric sensor, the receiving end of the photoelectric sensor will not detect the light signal due to the obstruction of the second detection unit 532, thereby triggering the output signal to realize the detection function of the second detection unit 532.
[0078] Continue to refer to Figure 5 As shown, the rotating assembly 500 also includes a third limiting member 591 and a fourth limiting member 592. The third limiting member 591 and the fourth limiting member 592 are respectively located on both sides of the rotating connecting seat 530 along the second direction y, and the angle between the fifth sensor 570 and the sixth sensor 580 is less than the angle of rotation of the rotating connecting seat 530 between the third limiting member 591 and the fourth limiting member 592.
[0079] In this embodiment, when the rotating connector 530 rotates around the first direction x to the fifth sensor 570 or the sixth sensor 580, and the sensor at that position does not trigger a signal, the control system will not control the second drive unit 510 to stop. The rotating connector 530 will continue to rotate around the first direction x. Since the angle between the fifth sensor 570 and the sixth sensor 580 is smaller than the angle of rotation of the rotating connector 530 between the third limit member 591 and the fourth limit member 592, the rotating connector 530, which continues to rotate around the first direction x, will abut against the third limit member 591 or the fourth limit member 592. The third limit member 591 or the fourth limit member 592 will mechanically and hard limit the rotating connector 530, thereby preventing the rotating connector 530 from rotating excessively around the first direction x, and further preventing the scanning member 110 from rotating excessively around the first direction x.
[0080] Specifically, in this embodiment, the rotary scanning device further includes a second encoder (not shown), which is connected to the drive shaft 520 to control the rotation angle and rotation speed of the drive shaft 520 around the first direction x, so as to precisely control the rotation of the scanning element 110 around the first direction x.
