Description

Technical Field

[0001] The present invention relates to the technical field of construction robots, and in particular to a receiving structure, a leveling machine and an adjustment method. Background Art

[0002] In traditional leveling machines, a receiving structure is usually used to send and receive leveling data. However, due to the influence of environmental factors, the traditional receiving structure has poor accuracy and blind spots in the 360-degree receiving range, which will cause the actual working error of the receiving structure to be large and cannot meet the needs of high-precision operations. Summary of the invention

[0003] Based on this, it is necessary to provide a receiving structure, a leveling machine and an adjustment method, aiming to solve the problems of blind spots in signal data reception and transmission and low signal reception accuracy in the prior art.

[0004] The technical solution is as follows:

[0005] A receiving structure comprises laser receiving units, wherein the number of the laser receiving units is at least three, the laser receiving units are arranged in sequence along a circumferential direction, and adjacent laser receiving units are arranged at an angle.

[0006] In the above-mentioned receiving structure, the laser receiving unit can be used to receive the laser signal emitted by the laser transmitter. The number of laser receiving units is at least three, and the laser receiving units are arranged in sequence along a circumferential direction. Then, different laser receiving units can receive the laser signal emitted by the same laser transmitter, and the range of receiving laser signals is wider, thereby preventing the existence of a receiving blind area. Since adjacent laser receiving units are arranged at an angle, when receiving the laser signal emitted by the same laser transmitter, different laser receiving units receive different exposure intensities. The exposure intensities obtained by different laser receiving units can be compared, and the angle of the receiving structure can be adjusted to maximize the exposure intensity of a laser receiving unit located in the middle. If the exposure intensity of the above-mentioned laser receiving unit is greater than the exposure intensity of the laser receiving units on both sides thereof, it means that this laser receiving unit is facing the laser transmitter, and responds faster and with higher accuracy when receiving the laser signal emitted by the laser transmitter. Therefore, by using the above-mentioned receiving structure, at least three laser receiving units can be used to expand the range of receiving laser signals, and the receiving structure can be adjusted according to the different exposure intensities of different laser receiving units to improve the response speed and accuracy, and reduce errors in the signal data receiving process.

[0007] In one embodiment, three of the laser receiving units are a first laser receiving unit, a second laser receiving unit, and a third laser receiving unit respectively. The first laser receiving unit and the third laser receiving unit are respectively disposed on both sides of the second laser receiving unit. The first laser receiving unit has a first receiving direction for receiving laser, the second laser receiving unit has a second receiving direction for receiving laser, and the third laser receiving unit has a third receiving direction for receiving laser. The included angle between the first receiving direction and the second receiving direction is a, where 0° < a ≤ 30°, and the included angle between the second receiving direction and the third receiving direction is b, where 0° < b ≤ 30°.

[0008] In one embodiment, the above receiving structure further includes a mounting base and a base. The laser receiving units are all disposed on the mounting base, and the mounting base is rotatably connected to the base.

[0009] In one embodiment, the above receiving structure further includes a slip ring. The slip ring is electrically connected to the laser receiving unit, and the mounting base is rotatably connected to the base through the slip ring.

[0010] In one embodiment, the mounting base includes a first fitting and a second fitting. A connecting space is formed between the first fitting and the second fitting. The stator of the slip ring is connected to the first fitting and extends into the connecting space. The stator of the slip ring is electrically connected to the laser receiving unit. The rotor of the slip ring is connected to the base. The laser receiving unit is disposed on the second fitting and outside the connecting space.

[0011] In one embodiment, the above receiving structure further includes a driving member for driving the mounting base to rotate relative to the base.

[0012] A leveling machine includes a main body and the receiving structure as described in any one of the above.

[0013] The above-mentioned leveling machine needs to use a laser transmitter to emit a laser signal when working. The laser receiving unit of the receiving structure can receive the laser signal to guide and control the operation of the leveling machine. The number of laser receiving units is at least three, and the laser receiving units are arranged in sequence along a circumferential direction. Then, different laser receiving units can receive the laser signal emitted by the same laser transmitter, and the range of receiving laser signals is larger, thereby preventing the existence of a receiving blind area. Since adjacent laser receiving units are arranged at an angle, when receiving the laser signal emitted by the same laser transmitter, different laser receiving units receive different exposure intensities, and different laser receiving units can be obtained. The exposure intensity is compared and the angle of the receiving structure is adjusted to make the exposure intensity of a laser receiving unit in the middle the maximum. The exposure intensity of the above laser receiving unit is greater than the exposure intensity of the laser receiving units on both sides of it, which means that this laser receiving unit is facing the laser transmitter, and responds faster and with higher accuracy when receiving the laser signal emitted by the laser transmitter. Therefore, through the receiving structure, at least three laser receiving units can be used to expand the range of receiving laser signals, and the receiving structure can be adjusted according to the different exposure intensities of different laser receiving units to improve the response speed and accuracy, reduce errors in the signal data receiving process, and make the leveling machine work with higher accuracy and less error.

[0014] An adjustment method comprises the following steps:

[0015] Obtaining exposure intensities of different laser receiving units in the receiving structure;

[0016] comparing the exposure intensities of different laser receiving units;

[0017] Using one of the laser receiving units located in the middle as a reference unit, and rotating the receiving structure if the exposure intensity of the reference unit is not the maximum value;

[0018] The above steps are repeated until the exposure intensity of the reference unit is greater than the exposure intensity of the remaining laser receiving units.

[0019] According to the above adjustment method, when receiving the laser signal emitted by the same laser transmitter, different laser receiving units receive different exposure intensities. The exposure intensities obtained by different laser receiving units can be compared, and the angle of the receiving structure can be adjusted so that the exposure intensity of a laser receiving unit located in the middle, that is, the reference unit, is the largest. If the exposure intensity of the reference unit is greater than the exposure intensity of the laser receiving units on both sides of it, it means that the reference unit is facing the laser transmitter, and responds faster and with higher accuracy when receiving the laser signal emitted by the laser transmitter, which can reduce errors in the signal data reception process.

[0020] In one of the embodiments, if the exposure intensity of one of the laser receiving units located in the middle is not the maximum value, all of the laser receiving units are rotated as a whole, specifically comprising the following steps:

[0021] If the exposure intensity of the laser receiving unit located on the left side of the reference unit is greater than the exposure intensity of the reference unit, rotating the receiving structure to the left;

[0022] If the exposure intensity of the laser receiving unit located on the right side of the reference unit is greater than the exposure intensity of the reference unit, the receiving structure is rotated rightward.

[0023] In one embodiment, after obtaining the exposure intensities of different laser receiving units in the receiving structure, the following steps are also included:

[0024] If the exposure intensities of the laser receiving units are all 0, the receiving structure is continuously rotated in one direction until the exposure intensity of at least one of the laser receiving units in the receiving structure is not 0. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, an embodiment discloses a receiving structure 100, including laser receiving units 110, the number of the laser receiving units 110 is at least three, the laser receiving units 110 are arranged in sequence along a circumferential direction, and adjacent laser receiving units 110 are arranged at an angle.

[0035] In the receiving structure 100, the laser receiving unit 110 can be used to receive the laser signal emitted by the laser transmitter 10. The number of the laser receiving units 110 is at least three, and the laser receiving units 110 are arranged in sequence along a circumferential direction. Then, different laser receiving units 110 can receive the laser signal emitted by the same laser transmitter 10, and the range of receiving the laser signal is larger, thereby preventing the existence of a receiving blind area. Since the adjacent laser receiving units 110 are arranged at an angle, when receiving the laser signal emitted by the same laser transmitter 10, different laser receiving units 110 receive different exposure intensities, and the exposure intensities obtained by different laser receiving units 110 can be compared. Ratio, and adjust the angle of the receiving structure so that the exposure intensity of the laser receiving unit 110 located in the middle is the largest. The exposure intensity of the above-mentioned laser receiving unit 110 is greater than the exposure intensity of the laser receiving units 110 on both sides thereof, which means that this laser receiving unit 110 is facing the laser emitter 10, and responds faster and with higher accuracy when receiving the laser signal emitted by the laser emitter 10. Therefore, by using the above-mentioned receiving structure 100, at least three laser receiving units 110 can be used to expand the range of receiving laser signals, and the receiving structure 100 can be adjusted according to the different exposure intensities of different laser receiving units 110 to improve the response speed and accuracy and reduce errors in the signal data receiving process.

[0036] As long as there is at least one laser receiving unit 110 on both sides of one of the laser receiving units 110, this laser receiving unit 110 can be used as a reference unit for exposure intensity comparison, and the reference unit can be used as the only instrument for receiving the laser signal of the laser transmitter 10. When the number of laser receiving units 110 is an even number, there will be two laser receiving units 110 located in the middle position. At this time, one of the laser receiving units 110 can be arbitrarily designated as the reference unit for comparison.

[0037] Specifically, the adjacent laser receiving units 110 are close to each other, and there is no gap or a small gap between the adjacent laser receiving units 110 , which can prevent the occurrence of a blind area where signals cannot be received between the adjacent laser receiving units 110 .

[0038] Optionally, the above-mentioned “circumferential direction” may be a circumferential direction centered on the laser emitter 10; or a circumferential direction centered on other places. In practical applications, the laser receiving units 110 in the receiving structure 100 cannot be distributed strictly in the circumferential direction centered on the laser emitter 10, and at least one laser receiving unit 110 located in the middle needs to be adjusted to face the laser emitter 10.

[0039] In one embodiment, if Figure 1 and Figure 2As shown, among them, the three laser receiving units 110 are respectively a first laser receiving unit 111, a second laser receiving unit 112 and a third laser receiving unit 113. The first laser receiving unit 111 and the third laser receiving unit 113 are respectively arranged on both sides of the second laser receiving unit 112. The first laser receiving unit 111 has a first receiving direction 111a for receiving laser, the second laser receiving unit 112 has a second receiving direction 112a for receiving laser, and the third laser receiving unit 113 has a third receiving direction 113a for receiving laser. The included angle between the first receiving direction 111a and the second receiving direction 112a is a, 0° < a ≤ 30°. The included angle between the second receiving direction 112a and the third receiving direction 113a is b, 0° < b ≤ 30°. When the included angle between two adjacent laser receiving units 110 is greater than 0° and less than or equal to 30°, the above three laser receiving units 110 can all receive the signal emitted by the laser emitter 10. Therefore, the receiving range of the data signal can be increased, and the blind area when receiving the laser signal can be eliminated. When the three laser receiving units 110 receive the laser signal, there will be a deviation between the standard receiving direction and the emitting direction of the laser, which affects the exposure intensity of the received laser. Only when the laser receiving unit 110 is directly opposite to the laser emitter 10, the exposure intensity of the received laser is the largest. Therefore, if the second laser receiving unit 112 is directly opposite to the laser emitter 10, the exposure intensity of the received laser by it must be greater than the exposure intensities of the first laser receiving unit 111 and the third laser receiving unit 113. Then, by comparing the exposure intensities of different laser receiving units 110 and rotating the receiving structure 100 to make the exposure intensity of the second laser receiving unit 112 the maximum value, it can be ensured that the second laser receiving unit 112 is directly opposite to the laser emitter 10, making the signal data transceiver response speed faster and the error smaller.

[0040] Specifically, after being adjusted by the above receiving structure 100,

[0041] Among them, a and b may be equal or not equal.

[0042] Optionally, a = 20°, b = 20°. At this time, the signal receiving range of the receiving structure 100 is relatively large, and each laser receiving unit 110 can receive the laser signal well.

[0043] In this specific embodiment, the number of the laser receiving units 110 is three. In other embodiments, the number of the laser receiving units 110 may be more than three.

[0044] In one of the embodiments, such as Figures 1 to 3As shown, the receiving structure 100 further includes a mounting seat 120 and a base 130. The laser receiving units 110 are all disposed on the mounting seat 120, and the mounting seat 120 is rotatably connected to the base 130. By rotating the mounting seat 120 relative to the base 130, the laser receiving units 110 can be adjusted as a whole until a laser receiving unit 110 located in the middle has the maximum exposure intensity.

[0045] In other embodiments, a laser receiving unit 110 located in the middle may be separately set as a rotatable structure. By rotating the laser receiving unit 110 so that the exposure intensity is greater than the exposure intensity of other laser receivers, errors in the signal receiving and sending process may also be reduced.

[0046] In one embodiment, if Figures 1 to 3 As shown, the receiving structure 100 further includes an electric slip ring 140, which is electrically connected to the laser receiving unit 110, and the mounting seat 120 is rotatably connected to the base 130 via the electric slip ring 140. The signal received by the laser receiving unit 110 can be exported via the electric slip ring 140, and the electric slip ring 140 will not cause twisting and bending of the wire during the rotation process, thereby increasing the rotatable angle of the mounting seat 120 relative to the base 130, and facilitating the rotation adjustment of the laser receiving unit 110 at a larger angle.

[0047] In other embodiments, the mounting seat 120 and the base 130 may be rotationally connected in other ways. For example, the mounting seat 120 may have a rotating shaft, the base 130 may have a matching hole, a bearing may be provided outside the rotating shaft, the rotating shaft may be inserted into the matching hole, and the bearing may be located between the rotating shaft and the inner wall of the matching hole.

[0048] In one embodiment, if Figures 1 to 3 As shown, the mounting seat 120 includes a first assembly part 121 and a second assembly part 122, a connection space is formed between the first assembly part 121 and the second assembly part 122, the stator of the electric slip ring 140 is connected to the first assembly part 121 and extends into the connection space, the stator of the electric slip ring 140 is electrically connected to the laser receiving unit 110, the rotor of the electric slip ring 140 is connected to the base 130, and the laser receiving unit 110 is arranged on the second assembly part 122 and is located outside the connection space. At this time, the wire of the laser receiving unit 110 can extend into the connection space and be electrically connected to the stator of the electric slip ring 140, and then the external circuit can be electrically connected to the rotor of the electric slip ring 140, so that the wire of the laser receiving unit 110 will not be bent or twisted during the rotation of the mounting seat 120, and the wire is stored in the connection space and can be protected.

[0049] In one embodiment, if Figures 1 to 3As shown, the receiving structure 100 further includes a driving member 150, which is used to drive the mounting seat 120 to rotate relative to the base 130. The driving member 150 can be used to realize the automatic rotation of the mounting seat 120 relative to the base 130, which is more convenient to control and more accurate in angle control.

[0050] Optionally, the driving member 150 drives the mounting seat 120 to rotate relative to the base 130 by belt transmission. Specifically, the receiving structure 100 further includes a transmission belt, which is sleeved outside the stator of the electric slip ring 140.

[0051] In other embodiments, gear transmission may be used to drive the mounting seat 120 to rotate relative to the base 130 .

[0052] Optionally, the driving member 150 is a motor.

[0053] In other embodiments, the rotation angle between the mounting base 120 and the base 130 may also be manually adjusted.

[0054] like Figures 1 to 3 As shown, an embodiment discloses a leveling machine, including a main body 200 and a receiving structure 100 as described above.

[0055] The above-mentioned leveling machine needs to use the laser transmitter 10 to emit laser signals when working. The laser receiving unit 110 of the receiving structure 100 can receive the laser signal to guide and control the operation of the leveling machine. The number of laser receiving units 110 is at least three, and the laser receiving units 110 are arranged in sequence along a circumferential direction. Then, different laser receiving units 110 can receive the laser signal emitted by the same laser transmitter 10, and the range of receiving laser signals is larger, thereby preventing the existence of a receiving blind area. Since adjacent laser receiving units 110 are arranged at an angle, when receiving the laser signal emitted by the same laser transmitter 10, different laser receiving units 110 receive different exposure intensities, and different laser receiving units 110 can be obtained. The exposure intensity received is compared, and the angle of the receiving structure is adjusted to make the exposure intensity of the laser receiving unit 110 located in the middle the maximum. The exposure intensity of the above-mentioned laser receiving unit 110 is greater than the exposure intensity of the laser receiving units 110 on both sides thereof, which means that this laser receiving unit 110 is facing the laser emitter 10, and responds faster and with higher accuracy when receiving the laser signal emitted by the laser emitter 10. Therefore, through the receiving structure 100, at least three laser receiving units 110 can be used to expand the range of receiving laser signals, and the receiving structure 100 can be adjusted according to the different exposure intensities of different laser receiving units 110 to improve the response speed and accuracy, reduce errors in the process of signal data reception, and make the leveling machine work with higher accuracy and less error.

[0056] Optionally, there are two receiving structures 100, and the two receiving structures 100 are spaced apart at the front end of the main body 200, so as to conveniently receive the signal of the laser transmitter 10 and adjust the leveling machine in time.

[0057] like Figure 4 As shown, an embodiment discloses an adjustment method, comprising the following steps:

[0058] S100, obtaining exposure intensities of different laser receiving units 110 in the receiving structure 100;

[0059] S200, comparing the exposure intensities of different laser receiving units 110;

[0060] S300, taking a laser receiving unit 110 located in the middle as a reference unit, and if the exposure intensity of the reference unit is not the maximum value, rotating the receiving structure 100;

[0061] S400 , repeat the above steps until the exposure intensity of the reference unit is greater than the exposure intensity of the remaining laser receiving units 110 .

[0062] According to the above adjustment method, when receiving the laser signal emitted by the same laser emitter 10, different laser receiving units 110 receive different exposure intensities. The exposure intensities obtained by different laser receiving units 110 can be compared, and the angle of the receiving structure can be adjusted so that the exposure intensity of a laser receiving unit 110 located in the middle, that is, the reference unit, is the largest. If the exposure intensity of the reference unit is greater than the exposure intensity of the laser receiving units 110 on both sides thereof, it means that the reference unit is facing the laser emitter 10, and responds faster and with higher accuracy when receiving the laser signal emitted by the laser emitter 10, thereby reducing errors in the signal data receiving process.

[0063] The “middle” mentioned above is a general term, and the definition of “reference unit” can also be: if there is at least one laser receiving unit 110 on both sides of a laser receiving unit 110, then this laser receiving unit 110 can be used as a reference unit.

[0064] The receiving structure 100 rotates around a central axis, which is arranged in a vertical direction. The receiving structure 100 can rotate as a whole or partially to adjust the positions of all the laser receiving units 110 .

[0065] In one embodiment, if the exposure intensity of the laser receiving unit 110 located in the middle is not the maximum value, all the laser receiving units 110 are rotated as a whole, which specifically includes the following steps:

[0066] If the exposure intensity of the laser receiving unit 110 located on the left side of the reference unit is greater than the exposure intensity of the reference unit, the receiving structure 100 is rotated to the left;

[0067] If the exposure intensity of the laser receiving unit 110 located on the right side of the reference unit is greater than the exposure intensity of the reference unit, the receiving structure 100 is rotated rightward.

[0068] The above-mentioned rotation adjustment method is more purposeful. As the reference unit rotates toward the side with higher exposure intensity, the exposure intensity of the laser that the reference unit can receive is also higher, so that the reference unit can be adjusted to face the laser emitter 10 as soon as possible to improve the response speed.

[0069] In other embodiments, all the laser receiving units 110 may rotate as a whole or in only one direction until the reference unit faces the laser emitter 10 and has the maximum exposure intensity.

[0070] In one embodiment, after obtaining the exposure intensities of different laser receiving units 110 in the receiving structure 100, the following steps are also included:

[0071] If the exposure intensities of the laser receiving units 110 are all 0, the receiving structure 100 is continuously rotated in one direction until the exposure intensity of at least one laser receiving unit 110 in the receiving structure 100 is not 0.

[0072] When the exposure intensity of the laser receiving unit 110 is all 0, it means that the receiving structure 100 as a whole is not aligned with the laser transmitter 10, and it is impossible to determine in which direction to rotate so that the laser receiving unit 110 can receive the laser signal of the laser transmitter 10 again. Therefore, the receiving structure 100 is continuously rotated in one direction until the exposure intensity of a laser receiving unit 110 is not 0. And when the exposure intensity of only one laser receiving unit 110 is not 0, this laser receiving unit 110 must be at the edge of the receiving structure 100, and the exposure intensity of the reference unit must be less than the above-mentioned laser receiving unit 110 with non-0 exposure intensity. The judgment can be started and the receiving structure 100 can be rotated until the reference unit is facing the laser transmitter 10.

[0073] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
