[0078] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0079] Combine Figures 1 to 4 As shown ( Figures 1 to 4 The top of the drawing is on the left side of the drawing). The embodiment of the present disclosure provides a device for controlling the position of a point. The device includes: a support frame 1, an X-axis drive device 2, a Y-axis drive device 3, and a Z-axis drive device 4. The support frame 1 is set at a preset height in a hanging manner. Figure 2 and Figure 3 The X-axis drive device 2 is mounted on the support frame 1. The X-axis drive device 2 includes an X-axis power output unit connected to an X-axis mounting portion 27. The X-axis mounting portion 27 is used to mount a microphone, which is defined as the X-axis microphone. The X-axis power output unit outputs power from the X-axis drive device 2 to drive the X-axis mounting portion 27 to move along the X-axis, thereby driving the X-axis microphone to move along the X-axis.

[0080] See also Figure 2 and Figure 4The Y-axis driving device 3 is slidably arranged on the supporting frame 1 and can be driven to move along the X-axis. The Y-axis driving device 3 and the X-axis power output unit can move along the X-axis under the drive of the X-axis power output unit. The Y-axis driving device 3 includes a Y-axis power output unit, and the Y-axis power output unit is connected to the Y-axis mounting unit 36. The Y-axis mounting unit 36 ​​is also used to install a microphone, which is defined as a Y-axis microphone. The Y-axis power output unit outputs the power of the Y-axis driving device 3 to drive the Y-axis mounting unit 36 ​​to move along the Y-axis, and then drives the Y-axis microphone to move along the Y-axis. Since the Y-axis driving device 3 can move along the X-axis due to being driven by the X-axis power output unit, the Y-axis microphone will move along the X-axis together with the Y-axis driving device 3. In this way, the Y-axis microphone can move along both the X-axis and the Y-axis.

[0081] Combine Figure 2 and Figure 4 As shown, the Z-axis drive device 4 is connected to the X-axis power output unit to move along the X-axis under the drive of the X-axis power output unit. Alternatively, the Z-axis drive device 4 is connected to the Y-axis power output unit to move along the X-axis under the drive of the Y-axis power output unit. Alternatively, the Z-axis drive device 4 is connected to both the X-axis power output unit and the Y-axis power output unit to move along the X-axis and Y-axis respectively under the drive of the X-axis power output unit and the Y-axis power output unit. The Z-axis drive device 4 includes: a Z-axis power output unit, and the Z-axis power output unit is connected to the Z-axis mounting portion 44. The Z-axis mounting portion 44 is also used to mount a microphone, which is defined as a Z-axis microphone. The Z-axis power output unit outputs the power of the Z-axis drive device 4 to drive the Z-axis mounting portion 44 to move along the Z-axis, thereby driving the Z-axis microphone to move along the Z-axis. In this way, the Z-axis microphone can be driven to move along the X-axis, Y-axis, and / or Z-axis.

[0082] Using the device for controlling the position of points provided by the embodiment of the present disclosure, the X-axis power output portion of the X-axis drive device 2 is connected to the X-axis mounting portion 27, thereby being able to drive the corresponding microphone to move along the X-axis. The Y-axis drive device 3 is connected to the X-axis power output portion, and the Y-axis power output portion is connected to the Y-axis mounting portion 36, thereby being able to drive the corresponding sensor to move along the X-axis and Y-axis. The Z-axis drive device 4 is connected to the X-axis power output portion and / or the Y-axis power output portion, thereby being able to be driven to move along the X-axis and / or the Y-axis. At the same time, the Z-axis power output portion is connected to the Z-axis mounting portion 44, thereby being able to drive the corresponding sensor to move along the X-axis, the Y-axis and / or the Z-axis. In this way, the microphone coordinates can be arranged quickly, safely, efficiently, accurately and fully automatically through multi-axis linkage. No manual operation is required, which improves the accuracy of the microphone position and saves manpower.

[0084] Alternatively, see Figures 1 to 4 The support frame 1 has a first side 11 and a second side 12. The first side 11 and the second side 12 are two opposite sides on the X axis. Optionally, the first side 11 is the front side of the support frame 1, and the second side 12 is the rear side of the support frame 1 (relative to the Figure 1 for example).

[0085] Alternatively, see Figure 5 The X-axis drive mechanism 21 includes an X-axis drive motor 211, which is fixed to the first side 11 of the support frame 1 via an X-axis motor bracket 212. The power output shaft of the X-axis drive motor 211 is in transmission connection with the X-axis transmission mechanism. Here, the power output shaft of the X-axis drive motor 211 serves as a first drive output end.

The second transmission assembly 23 is also in transmission connection with the first drive output end, that is, in transmission connection with the power output shaft of the X-axis drive motor 211, so as to be driven by the X-axis drive device 2. Furthermore, the second transmission assembly 23 is also connected to the X-axis mounting portion 27 to drive the X-axis mounting portion 27 to move along the X-axis. The transmission speed of the first transmission assembly 22 is greater than the transmission speed of the second transmission assembly 23. Thus, the movement speed of the Y-axis drive device 3 along the X-axis is greater than the movement speed of the X-axis mounting portion 27 along the X-axis. In this way, positional interference between the Y-axis driving device 3 and the X-axis mounting portion 27 can be avoided, and the X-axis mounting portion 27 and the Y-axis driving device can be driven to their respective positions by synchronously driving the X-axis driving device on the X-axis mounting portion 27 and the Y-axis driving device.

[0087] Optionally, the first transmission assembly 22 and the second transmission assembly 23 are arranged along the Z axis (up and down).

[0088] Optionally, the first transmission assembly 22 includes: a first gear assembly 221, a second gear assembly 222 and a first conveyor belt 223. Figure 5 The first gear assembly 221 is provided on the first side 11 of the support frame 1 and is in driving connection with the first drive output end, that is, in driving connection with the power output shaft of the X-axis drive motor 211, so as to be driven by the X-axis drive device 2. Figure 6 The second gear assembly 222 is disposed on the second side 12 of the support frame 1 and can be driven to rotate by power. The first conveyor belt 223 is sleeved on the first gear assembly 221 and the second gear assembly 222. When the first gear assembly 221 rotates, it can transmit power to the first conveyor belt 223. The first conveyor belt 223 then transmits power to the second gear assembly 222, thereby causing the second gear assembly 222 to rotate. Here, the first conveyor belt 223 serves as one of the X-axis power output parts. The Y-axis drive device 3 is on the first conveyor belt 223 to follow the first conveyor belt 223 and move along the X-axis.

[0089] Optionally, continue with Figure 5 The first gear assembly 221 includes: a first driving wheel 2211 and a first driven wheel 2212. The first driving wheel 2211 is transmission-connected to the first drive output end, that is, the first driving wheel 2211 is arranged on the power output shaft of the X-axis drive motor 211. In this way, the X-axis drive motor 211 transmits power to the first driving wheel 2211 through the power output shaft, and drives the first driving wheel 2211 to rotate. The first driven wheel 2212 is rotatably arranged on the first side 11 of the support frame 1. Specifically, a first gear bracket 24 is provided on the first side 11 of the support frame 1. A first mounting post 241 is provided on the first gear bracket 24. The first driven wheel 2212 is rotatably mounted on the first mounting post 241 and is arranged parallel to the first driving wheel 2211. The first side of the first conveyor belt 223 is mounted on the first driving wheel 2211 and the first driven wheel 2212. In this way, when the first driving wheel 2211 is driven to rotate, power can be transmitted to the first conveyor belt 223, and the first conveyor belt 223 then drives the first driven wheel 2212 to rotate.

[0090] Optionally, the X-axis motor bracket 212 is connected to the first gear bracket 24 to make the X-axis drive motor 211 more stable.

[0091] Optionally, continue with Figure 6The second gear assembly 222 includes a second driven wheel 2221 and a third driven wheel 2222. Both the second driven wheel 2221 and the third driven wheel 2222 are rotatably mounted on the second side 12 of the support frame 1. Specifically, a second gear bracket 25 is provided on the second side 12 of the support frame 1. The second gear bracket 25 is provided with a second mounting post 251 and a third mounting post 252. The second driven wheel 2221 is rotatably mounted on the second mounting post 251, and the third driven wheel 2222 is rotatably mounted on the third mounting post 252. Simultaneously, the second driven wheel 2221 and the third driven wheel 2222 are arranged side by side. The second side of the first conveyor belt 223 is mounted on the second driven wheel 2221 and the third driven wheel 2222. Thus, when the first conveyor belt 223 rotates, it can drive the second driven wheel 2221 and the third driven wheel 2222 to rotate.

[0092] Optionally, the second transmission assembly 23 includes: a third gear assembly 231, a fourth gear assembly 232 and a second conveyor belt 233. Figure 5 The third gear assembly 231 is disposed on the first side 11 of the support frame 1 and is in transmission connection with the first drive output end, that is, in transmission connection with the power output shaft of the X-axis drive motor 211, so as to be driven by the X-axis drive device 2. That is, the third gear assembly 231 and the first gear assembly 221 are driven by the same power source. Figure 6 The fourth gear assembly 232 is disposed on the second side 12 of the support frame 1 and can be driven to rotate by power. The second conveyor belt 233 is sleeved on the third gear assembly 231 and the fourth gear assembly 232. When the third gear assembly 231 rotates, it can transmit power to the second conveyor belt 233. The second conveyor belt 233 then transmits power to the fourth gear assembly 232, thereby rotating the fourth gear assembly 232. Here, the second conveyor belt 233 serves as the second X-axis power output unit. The X-axis mounting portion 27 is placed on the second conveyor belt 233 so that it can move along the X-axis along with the second conveyor belt 233 together with the X-axis microphone.

[0093] Optionally, see again Figure 5The third gear assembly 231 includes a second driving wheel 2311 and a fourth driven wheel 2312. The second driving wheel 2311 is drivingly connected to the first drive output end, that is, the second driving wheel 2311 is mounted on the power output shaft of the X-axis drive motor 211. Thus, the X-axis drive motor 211 transmits power to the second driving wheel 2311 via the power output shaft, driving the second driving wheel 2311 to rotate. In other words, the power output shaft of the X-axis drive motor 211 simultaneously drives the first driving wheel 2211 and the second driving wheel 2311. The fourth driven wheel 2312 is rotatably mounted on the first side 11 of the support frame 1. Specifically, the fourth driven wheel 2312 is rotatably mounted on the first mounting post 241 and is arranged parallel to the second driving wheel 2311. The first side of the second conveyor belt 233 is mounted on the second driving wheel 2311 and the fourth driven wheel 2312. In this way, when the second driving wheel 2311 is driven to rotate, power can be transmitted to the second conveyor belt 233, and the second conveyor belt 233 then drives the fourth driven wheel 2312 to rotate.

[0094] Optionally, see again Figure 6 The fourth gear assembly 232 includes: a fifth driven wheel 2321 and a sixth driven wheel 2322. The fifth driven wheel 2321 and the sixth driven wheel 2322 are both rotatably disposed on the second side 12 of the support frame 1. Specifically, the fifth driven wheel 2321 is rotatably mounted on the second mounting post 251, and the sixth driven wheel 2322 is rotatably mounted on the third mounting post 252. At the same time, the fifth driven wheel 2321 and the sixth driven wheel 2322 are arranged in parallel. The second side of the second conveyor belt 233 is mounted on the fifth driven wheel 2321 and the sixth driven wheel 2322. In this way, when the second conveyor belt 233 rotates, it can drive the fifth driven wheel 2321 and the sixth driven wheel 2322 to rotate.

[0095] As can be seen from the above, the structures of the first transmission assembly 22 and the second transmission assembly 23 are similar. Both are driven by the X-axis drive motor 211. The diameter of the first driving wheel 2211 is larger than the diameter of the second driving wheel 2311. In this way, the transmission speed of the first transmission assembly 22 can be greater than the transmission speed of the second transmission assembly 23.

[0096] Optionally, the X-axis transmission mechanism further includes: a first beam 26. The length direction of the first beam 26 is arranged along the Y-axis, and the first beam 26 is slidably arranged on the support frame 1. Specifically, see Figure 4 、 79, a first slider 261 and a second slider 262 are respectively provided on one side of the first crossbeam 26 and near its two ends, and a first slide rail 13 and a second slide rail 14 are respectively provided on both sides of the support frame 1. The first slide rail 13 is slidably embedded in the first slider 261, and the second slide rail 14 is slidably embedded in the second slider 262. In this way, the first crossbeam 26 can slide on the support frame 1. See again Figure 2 The X-axis mounting portion 27 is connected to the first beam 26. In this way, when the second conveyor belt 233 drives the X-axis mounting portion 27 to move along the X-axis, the X-axis mounting portion 27 can drive the first beam 26 to move along the X-axis. Here, the first beam 26 serves as the third X-axis power output portion.

[0097] Optionally, see again Figure 4 The Z-axis drive device 4 includes a first Z-axis drive device 401 and / or a second Z-axis drive device 402. The first Z-axis drive device 401 and / or the second Z-axis drive device 402 are slidably mounted on the first crossbeam 26. Thus, when the first crossbeam 26 moves along the X-axis, the first Z-axis drive device 401 and / or the second Z-axis drive device 402 also move along the X-axis. In this manner, the Z-axis microphone mounted on the Z-axis drive device 4 can be driven by the Z-axis drive device 4 to move along the Z-axis, and can also move along the X-axis along with the Z-axis drive device.

[0098] Optionally, the first Z-axis driving device 401 and the second Z-axis driving device 402 have the same structure and correspond one-to-one to the Z-axis microphones.

[0099] Optionally, the Y-axis driving device 3 includes: a second crossbeam 31, a Y-axis driving mechanism 32 and a Y-axis transmission mechanism. Figure 4 The length direction of the second crossbeam 31 is arranged along the Y axis, and the second crossbeam 31 is slidably arranged on the support frame 1. Specifically, see Figure 7 and Figure 9 A third slider 311 and a fourth slider 312 are respectively provided on one side of the second crossbeam 31 and near its two ends. The first slide rail 13 is slidably embedded in the third slider 311, and the second slide rail 14 is slidably embedded in the fourth slider 312.

In this way, the second crossbeam 31 can move along the X-axis driven by the first conveyor belt 223. The Y-axis drive mechanism 32 is provided on the second crossbeam 31. The Y-axis drive mechanism 32 includes a second drive output end. The Y-axis transmission mechanism is provided with the second crossbeam 31 and is in transmission connection with the second drive output end. In this way, the Y-axis transmission mechanism can move along the Y-axis under the action of the power output by the Y-axis drive mechanism 32.

[0100] See also Figure 2 The first side 11 of the supporting frame 1 , the first crossbeam 26 , the second crossbeam 31 and the second side 12 of the supporting frame 1 are sequentially arranged along the X-axis.

[0101] Optionally, see again Figure 4 The Z-axis drive device 4 further includes a third Z-axis drive device 403. The third Z-axis drive device 403 is connected to the second crossbeam 31. Thus, when the second crossbeam 31 moves along the X-axis, the third Z-axis drive device 403 can also move along the X-axis. This allows the Z-axis microphone, which is mounted on the third Z-axis drive device 403, to be driven by the third Z-axis drive device 403 and to move along both the Z-axis and the X-axis.

[0102] Alternatively, see Figure 8 The Y-axis drive mechanism 32 includes a Y-axis drive motor 321 secured to the second crossbeam 31 via a Y-axis motor bracket 322.

Figure 7 and Figure 9 The driven wheel assembly 35 is mounted on the second crossbeam 31. The third conveyor belt 34 is mounted on the third driving wheel 33 and the driven wheel assembly 35. When the third driving wheel 33 rotates, it drives the third conveyor belt 34 to rotate. The third conveyor belt 34 then drives the driven wheel assembly 35 to rotate. Here, the third conveyor belt 34 serves as one of the Y-axis power output components.

[0104] The Y-axis mounting portion 36 is disposed on the third conveyor belt 34. In this way, when the third conveyor belt 34 moves, it can drive the Y-axis microphone installed on the Y-axis mounting portion 36 to move along the Y-axis.

[0105] Optionally, the third conveyor belt 34 is sleeved on the third driving wheel 33 and the driven wheel assembly 35, thereby forming an inner conveying side 341 and an outer conveying side 342. Specifically, the side of the third conveyor belt 34 facing the second side 12 of the support frame 1 is the outer conveying side 342, and the side facing the first side 11 of the support frame 1 is the inner conveying side 341.

[0106] The Y-axis mounting portion 36 includes a first Y-axis mounting portion 361 and a second Y-axis mounting portion 362. Figure 7 The first Y-axis mounting portion 361 is provided on the inner conveying side 341 and is slidably connected to the second crossbeam 31, so that the first Y-axis mounting portion 361 can move smoothly. Specifically, the side of the second crossbeam 31 facing the first side 11 of the support frame 1 is provided with a third slide rail and a fourth slide rail. The first Y-axis mounting portion 361 is provided with a fifth slider 363, and the third slide rail is slidably embedded in the fifth slider 363. In this way, the first Y-axis mounting portion 361 can slide on the second crossbeam 31. Figure 9 , the second Y-axis mounting portion 362 is arranged on the outer conveying side 342, and is slidably connected to the second crossbeam 31. Specifically, the second Y-axis mounting portion 362 is provided with a sixth slider 364, and the fourth slide rail is slidably embedded in the sixth slider 364. In this way, the second Y-axis mounting portion 362 can slide on the second crossbeam 31. The first Y-axis mounting portion 361 and the second Y-axis mounting portion 362, one is arranged on the inner conveying side 341, and the other is arranged on the outer conveying side 342. In this way, when the third conveyor belt 34 is conveying, the first Y-axis mounting portion 361 and the second Y-axis mounting portion 362 can follow and move along the Y-axis, and the two move toward each other: move toward the middle of the support frame 1, or, the two move in opposite directions: move toward both sides of the support frame 1.

[0107] Optionally, the second crossbeam 31 has a first position and a second position, and the two positions are respectively arranged near two ends of the second crossbeam 31 .

[0108] Optionally, the driven wheel assembly 35 includes: a seventh driven wheel 351 and an eighth driven wheel 352, which are rotatably disposed at the first position and the second position of the second beam 31, that is, disposed on the second beam 31, and are respectively disposed on both sides of the third driving wheel 33. Figure 7 Specifically, the third gear bracket 353 is set at the first position, and both ends of the fourth mounting column 354 are connected to the top and bottom of the third gear bracket 353. The seventh driven wheel 351 is rotatably set on the fourth mounting column 354. Figure 9The fourth gear bracket 355 is positioned in the second position, and the ends of the fifth mounting post 356 are connected to the top and bottom of the fourth gear bracket 355. The eighth driven pulley 352 is rotatably mounted on the fifth mounting post 356. The third driving pulley 33 is positioned between the seventh driven pulley 351 and the eighth driven pulley 352. The third conveyor belt 34 is sleeved around the seventh driven pulley 351, the third driving pulley 33, and the eighth driven pulley 352.

[0109] Alternatively, see Figure 8 The Y-axis transmission mechanism further includes a tensioning assembly 37 . The tensioning assembly 37 is mounted on the second crossbeam 31 . The third conveyor belt 34 is also sleeved on the tensioning assembly 37 , which in turn stretches and tensions the third conveyor belt 34 , thereby preventing interference between the inner conveying side 341 and the outer conveying side 342 of the third conveyor belt 34 .

[0110] Optionally, the tensioning assembly 37 includes: one or more first tensioning pulleys 371. The first tensioning pulley 371 is rotatably disposed on the second beam 31. Specifically, the fifth gear bracket 372 is disposed on the Y-axis motor bracket 322, and the two ends of the sixth mounting column 373 are connected to the top and bottom of the fifth gear bracket 372. The first tensioning pulley 371 is rotatably disposed on the sixth mounting column 373. Optionally, when there are multiple first tensioning pulleys 371, the fifth gear bracket 372 can be directly disposed on the second beam 31 in addition to being disposed on the Y-axis motor bracket 322. The third conveyor belt 34 is also sleeved on the first tensioning pulley 371. In this way, the tensioning assembly 37, the third driving pulley 33, the seventh driven pulley 351 and the eighth driven pulley 352 cooperate to support and tension the third conveyor belt 34.

[0111] When the first tensioning wheel 371 is mounted on the Y-axis motor bracket 322, a predetermined distance exists between the first tensioning wheel 371 and the third driving wheel 33 on the X-axis. Furthermore, different sides of the third conveyor belt 34 contact the first tensioning wheel 371 and the third driving wheel 33, respectively. Specifically, the third driving wheel 33 contacts the inner conveying side 341 of the third conveyor belt 34, while the first tensioning wheel 371 contacts the outer conveying side 342 of the third conveyor belt 34. The third driving wheel 33, the seventh driven wheel 351, and the eighth driven wheel 352 are staggered relative to each other on the X-axis. The first tensioning wheel 371, the seventh driven wheel 351, and the eighth driven wheel 352 are also staggered relative to each other on the X-axis. This, in conjunction with the first tensioning wheel 371 and the third driving wheel 33, allows the third conveyor belt 34 to be stretched and tensioned in different directions.

[0112] When the first tensioning wheel 371 is directly disposed on the second crossbeam 31, the first tensioning wheel 371 is located between the Y-axis motor bracket 322 and the third gear bracket 353, or between the Y-axis motor bracket 322 and the fourth gear bracket 355. In this way, the portion of the third conveyor belt 34 between the third driving wheel 33 and the seventh driven wheel 351 / eighth driven wheel 352 can be stretched.

The third conveyor belt 34 is arranged on the second tensioning wheel 374, the third driving wheel 33 and the third tensioning wheel 375 in a staggered manner along the direction of the Y-axis. Specifically, the third conveyor belt 34 is first mounted on the front side of the second tensioning wheel 374 (the side facing the second side 12 of the support frame 1), then mounted on the rear side of the third driving wheel 33 (the side facing the first side 11 of the support frame 1), and then mounted on the front side of the third tensioning wheel 375 (the side facing the second side 12 of the support frame 1). In this way, the third conveyor belt 34 can be further tensioned.

The length direction of the first longitudinal beam 38 is arranged along the X-axis, and the first longitudinal beam 38 is connected to the first Y-axis mounting portion 361.

When the second crossbeam 31 moves along the Y-axis with the first longitudinal beam 38, the first Z-axis drive device 401 can follow and move along the Y-axis. In this way, the first Z-axis drive device 401 can move along both the X-axis and the Y-axis. The Z-axis microphone installed on the first Z-axis drive device 401 can realize three-axis position adjustment on the X-axis, Y-axis and Z-axis.

When the second crossbeam 31 moves along the Y-axis with the second longitudinal beam 39, the second Z-axis drive device 402 can follow and move along the Y-axis. In this way, the second Z-axis drive device 402 can move along both the X-axis and the Y-axis. The Z-axis microphone installed on the second Z-axis drive device 402 can realize three-axis position adjustment on the X-axis, Y-axis and Z-axis.

The first connecting frame 43 is connected to the seventh slider 4011 and the ninth slider 263, respectively. Thus, the first Z-axis drive device 401 is slidably connected to both the first crossbeam 26 and the first longitudinal beam 38, enabling movement along both the X-axis and the Y-axis.
