Description

Technical Field

[0001] The invention relates to an orientation adjustment technology, and in particular to a collimation correction device and a method and system thereof. Background Art

[0002] For various widely used wireless transmission technologies, such as radio waves, millimeter waves, light waves, sound waves, etc., by calibrating the signal source to send signals at a non-deflection angle, the stability and efficiency of wireless transmission can be maximized. Therefore, how to accurately calibrate the collimation of the signal source is a very important technology.

[0003] Please refer to Figure 1 , is a known collimation correction system 9, which uses dual-transmitting and dual-receiving lasers to calibrate the collimation between the object end / signal source emitting end (corresponding to the object carrier 90A) and the signal receiving / testing end (corresponding to the receiving end carrier 90B), including a first point laser emitting unit 91, a second point laser emitting unit 92, a first laser receiving hole 93 and a second laser receiving hole 94. The first point laser emitting unit 91 and the second point laser emitting unit 92 are used to emit a point laser light; theoretically, when the point laser light is incident vertically on a plane, the laser spot formed will be in a point shape. The first point laser emitting unit 91 and the second laser receiving hole 94 are respectively located on the object to be tested stage 90A and the receiving end stage 90B, and the light emitting position of the first point laser emitting unit 91 overlaps the center of a object to be tested (not shown, for example, a signal emitting source) in the direction of the laser light emitted by it, and the second laser receiving hole 94 is coplanar with the light emitting position of the first point laser emitting unit 91, and there is a first distance between their centers; the second point laser emitting unit 92 and the first laser receiving hole 93 are respectively located on the receiving end stage 90B and the object to be tested stage 90A, and the first laser receiving hole 93 is coplanar with the light emitting position of the second point laser emitting unit 92, and there is a second distance between their centers, and the second distance is equal to the first distance. Thus, by adjusting the position and angle of the object carrier 90A and the receiving end carrier 90B, the light emitted by the first point laser emitting unit 91 and the second point laser emitting unit 92 are respectively incident on the second laser receiving hole 94 and the first laser receiving hole 93 at the same time, so as to achieve the effect of correcting the collimation.

[0004] In addition, in the above-mentioned known collimation correction system 9, since the laser light actually emitted by each laser emitting unit 91, 92 may have an unexpected deviation in position or angle with the emitting hole (the light emitting position) on its housing, in the case of using multiple laser emitting units, a greater cumulative error will be generated, thereby reducing the accuracy and reliability of the collimation correction. In addition, when the distance between the transmission end and the receiving end of the laser is long (for example, more than 2 meters), the laser light spot generated at the receiving end (especially on a plane) may diverge into an irregular shape (for example, a kidney shape or other non-centrally symmetrical shape) and the position of the laser center point cannot be confirmed, resulting in the collimation correction cannot be achieved or cannot be calibrated. Although the above-mentioned correction deviation situation can use a high-precision laser device to reduce the accumulated deviation of the instrument or operation error, it will increase the size and cost of the device, so it cannot be widely used in various wireless transmission collimation calibration work.

[0005] In view of this, the conventional collimation correction technology still needs to be improved. Summary of the invention

[0011] The term "coupling" as used throughout the present invention includes direct or indirect electrical and / or signal connections, which can be selected by those skilled in the art according to usage requirements.

[0012] The similar terms such as "combination", "assembly" or "assembly" described in the present invention mainly include the connection that can be separated without destroying the components, or the connection that makes the components inseparable, which can be selected by those with ordinary knowledge in the field according to the materials of the components to be connected or the assembly requirements.

[0013] The present invention provides an alignment correction device, comprising: a main body, comprising: a reference center, located in an alignment plane, a center axis perpendicular to the alignment plane and passing through the reference center; a first alignment point, located on a first plane parallel to the alignment plane, the reference center is vertically projected onto the first plane to be defined as a first reference reference center; the first alignment point and the first reference reference center are spaced apart from each other, and the direction of the line between the first alignment point and the first reference reference center is defined as a first alignment axis; and a second alignment point, located in a second plane parallel to the alignment plane, the reference center is vertically projected onto the second plane to be defined as a second reference reference center, the second alignment point is aligned with the second reference reference center The centers are spaced apart from each other, and the direction of the line between the second alignment point and the second reference datum center is defined as a second alignment axis; among the center plane, the first plane and the second plane, at least two are spaced apart from each other; the first alignment axis and the second alignment axis are vertically projected to any reference plane parallel to the center plane, and the first alignment axis and the second alignment axis are respectively projected onto the reference plane to form a corresponding first projection axis and a second projection axis, the first projection axis and the second projection axis form an intersection in their extension direction, and the center axis intersects at the intersection through the reference plane, there is an alignment angle between the first projection axis and the second projection axis, and the alignment angle is not equal to 0 degrees or 180 degrees.

[0014] Accordingly, the collimation correction device of the present invention has a reference center, a first alignment point, and a second alignment point, and at least two of the collimation center plane, the first plane, and the second plane are arranged to be spaced from each other, so that the corresponding correction method and system can be easily implemented. In addition, the collimation correction device can only use a single light source device to calibrate the collimation in the subsequent collimation correction operation to avoid the situation of multiple cumulative errors caused by using multiple light source devices, and can achieve the effect of improving the accuracy and reliability of the collimation correction; in addition, the corresponding light source device can be independently arranged outside the body of the collimation correction device to simplify the connection relationship between the devices, so that the hardware configuration of the correction operation is simpler.

[0015] Wherein, each of the first alignment point and the second alignment point is provided with a light sensor, so that the collimation can be corrected according to whether each light sensor actually senses the light used for calibration alignment, thereby improving the correction accuracy.

[0016] Wherein, the reference center is provided with a light sensor, so that it is possible to judge whether the collimation is corrected based on more light sensors arranged at different positions, thereby having the effect of improving the correction accuracy.

[0017] The first alignment point and the second alignment point can rotate relative to each other around the mandrel to change the alignment angle. In this way, the alignment angle of the collimation correction device can be matched with light source devices with different light angles, which has the effect of improving the convenience and flexibility of the correction operation.

[0018] The alignment angle is 90 degrees. Thus, the alignment angle of the collimation correction device can be matched with a light source device of a relatively wide range of general specifications, which has the effect of improving the convenience of the correction operation.

[0019] The main body has a first component and a second component; the first component has a first component plane, and the first component plane has the reference center and the first alignment point; the second component has a second component plane parallel to the first component plane, and the second component plane has the second alignment point; the first component plane and the second component plane are spaced apart from each other. In this way, in the alignment correction operation, the first component plane has a reference center used as an alignment reference point, and the first and second component planes respectively have point features at two different positions for confirming whether the alignment is correct, and the alignment direction to be aligned is defined by the spaced planes, so that the alignment correction device has the effect of simple structure configuration.

[0020] The main body has a first component and a second component; the first component has a first component plane, and the first component plane has the reference center; the second component has a second component plane parallel to the first component plane, and the second component plane has the first alignment point and the second alignment point; the first component plane and the second component plane are spaced apart from each other. In this way, in the alignment correction operation, the first component plane has the reference center used as the alignment reference point, and the second component plane has point features at two different positions used to confirm whether the alignment is correct, and the alignment direction to be aligned is defined by the spaced planes, so that the alignment correction device has the effect of simple structure configuration.

[0021] The collimation correction method of the present invention is applied to a light source device and a collimation correction device as described above. The light emitted by the light source device generates a first line segment light and a second line segment light on a target plane. The first line segment light and the second line segment light have a light angle on the target plane and intersect at an intersection, and the light angle is equal to the alignment angle. The method includes: adjusting the position or angle of the light source device or the collimation correction device in a three-dimensional coordinate system so that the light emitted by the light source device passes through the reference center, the first alignment point and the second alignment point at the same time.

[0022] The collimation correction system of the present invention comprises: a light source device; a collimation correction device as described above; and an adjustment device, wherein the light source device or the collimation correction device is arranged on the adjustment device, and the adjustment device is used to adjust the position and angle of the light source device or the collimation correction device arranged thereon in three axes in a three-dimensional coordinate system, and to perform the collimation correction method as described above.

[0023] Accordingly, the collimation correction method and system of the present invention can be implemented by using a light source device and a collimation correction device that are independently arranged, and has the effect of simple hardware configuration. In addition, only a single light source device can be used to correct the collimation, so as to avoid the situation where multiple cumulative errors are generated by using multiple light source devices, and the accuracy and reliability of the collimation correction can be improved.

[0024] Wherein, in the case where a light sensor is provided at each of the first alignment point and the second alignment point, or in the case where a light sensor is provided at each of the first alignment point, the second alignment point and the reference center, the collimation correction system further comprises a processor, the processor is coupled to each of the light sensors and the adjustment device, and the processor controls the adjustment device to adjust at least one of the three-axis position and three-axis angle of the light source device or the collimation correction device in the three-dimensional coordinate system according to the situation that each of the light sensors receives the light emitted by the light source device. In this way, the collimation can be corrected according to whether each of the light sensors actually senses the light used for calibration alignment, which has the effect of improving the correction accuracy. In addition, through the connection and mutual operation relationship between the collimation adjustment device, the light source device, the adjustment device, the light sensor and the processor, the effect of automating the collimation correction operation can be achieved.

[0025] Wherein, the processor has a corresponding preset threshold corresponding to each of the optical sensors; in the case where the processor determines that the light intensity received by one of the optical sensors does not exceed the corresponding preset threshold, the processor determines that the light emitted by the light source device has not passed through the optical sensor, and controls the adjustment device to adjust at least one of the three-axis positions and three-axis angles of the light source device or the collimation correction device in the three-dimensional coordinate system, so that the light emitted by the light source device passes through each of the optical sensors and is not less than the corresponding preset threshold. In this way, by determining whether the light intensity received by one of the optical sensors exceeds the corresponding preset threshold through the processor, the effect of automating the collimation correction operation can be achieved.

DETAILED DESCRIPTION

[0036] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are specifically cited below and described in detail with reference to the accompanying drawings; in addition, those marked with the same symbols in different drawings are regarded as the same and their descriptions will be omitted.

[0037] like Figure 2 As shown, it is a preferred embodiment of the collimation correction system of the present invention, which may include a collimation correction device 1, a light source device 2 and an adjustment device 3, and the light source device 2 or the collimation correction device 1 is arranged on the adjustment device 3.

[0038] It should be noted that the collimation correction device 1 or the light source device 2 is “disposed” on the adjustment device 3, which means that the collimation correction device 1 or the light source device 2 can be “directly combined” or “indirectly combined” with the adjustment device 3; especially in the “indirect combination” (such as Figure 2As shown in the figure, a target object T to be calibrated (which may be a signal transmitting device or a signal receiving / testing device) is firstly combined with the adjustment device 3, and the collimation correction device 1 is then combined with the target object T to be calibrated, in particular, the reference center C is aligned with a center position of the target object T to be calibrated. Specifically, when the target object T to be calibrated is a signal transmitting device, the center position refers to the center point of the signal position generated by the signal transmitting device; when the target object T to be calibrated is a signal receiving device, the center position refers to the center point of the receiving part of the signal receiving device for receiving the signal.

[0039] like Figure 2 and 3 As shown, the collimation correction device 1 has a body 10, and the body 10 includes a reference center C, a first alignment point N1, and a second alignment point N2. The reference center C defines an alignment plane PC and a center axis AC, and the reference center C is located on the alignment plane PC. The center axis AC is perpendicular to the alignment plane PC and passes through the reference center C. The first alignment point N1 and the second alignment point N2 respectively define a first plane P1 and a second plane P2, and the first plane P1 and the second plane P2 are parallel to the alignment plane PC, and at least two of the alignment plane PC, the first plane P1 and the second plane P2 are spaced from each other; in addition, the reference center C is vertically projected onto the first plane P1 and the second plane P2 to define a first reference reference center C1 and a second reference reference center C2, respectively.

[0040] The first alignment point N1 is located on the first plane P1, the first alignment point N1 is spaced apart from the first reference center C1, and the direction of the line between the first alignment point N1 and the first reference center C1 is defined as a first alignment axis A1. The second alignment point N2 is located on the second plane P2, the second alignment point N2 is spaced apart from the second reference center C2, and the direction of the line between the second alignment point N2 and the second reference center C2 is defined as a second alignment axis A2.

[0041] The first alignment axis A1 and the second alignment axis A2 can be vertically projected onto a reference plane PR parallel to the center plane PC to form a corresponding first projection axis A1' and a second projection axis A2', respectively. The first projection axis A1' and the second projection axis A2' form an intersection NI in their extending directions. There is an alignment angle θ between the first projection axis A1' and the second projection axis A2'. A , and the alignment angle θ A is not equal to 0 degrees or 180 degrees; preferably, the alignment angle θ Ais 90 degrees.

[0042] like Figure 4 As shown, the light emitted by the light source device 2 generates a first line segment light L1 and a second line segment light L2 on a target plane PT, and the first line segment light L1 and the second line segment light L2 have a light angle θ on the target plane PT. B and intersect at an intersection point NL, and the light angle θ B The alignment angle θ A Preferably, the light angle θ B The first line segment light L1 and the second line segment light L2 form a cross laser beam. For example, the light source device 2 may be a cross laser level. In addition, the present invention is not limited thereto.

[0043] According to the configuration relationship between the collimation correction device 1 and the light source device 2, the present invention has a collimation correction method correspondingly. The collimation correction method can make the light emitted by the light source device 2 pass through the reference center C, the first alignment point N1 and the second alignment point N2 at the same time, so that the collimation correction device 1 and the light source device 2 have consistent collimation. In other words, in the case of consistent collimation, the intersection NL formed by the first line segment light L1 and the second line segment light L2 is aligned with the reference center C (especially overlapped), the first line segment light L1 passes through one of the first alignment point N1 and the second alignment point N2, and the second line segment light L2 passes through the other of the first alignment point N1 and the second alignment point N2.

[0044] Optionally, the structure configuration of the collimation correction device 1 has a corresponding adjustable connection relationship, so that the first alignment point N1 and the second alignment point N2 can rotate relative to each other around the central axis AC to change the alignment angle θ between the first alignment axis A1 and the second alignment axis A2. A Similarly, the light angle θ corresponding to the first line segment light L1 and the second line segment light L2 emitted by the light source device 2 is B It can also be adjusted accordingly. It should be noted that the above angle (alignment angle θ A Angle θ with light B ) can be implemented by applying known technologies and can be understood by those with ordinary knowledge in the field, so it is not described in detail.

[0045] Optionally, a light sensor (not shown) is provided on each of the first alignment point N1 and the second alignment point N2; preferably, a light sensor is provided on each of the reference center C, the first alignment point N1, and the second alignment point N2. In this way, through the light sensors provided on the first alignment point N1, the second alignment point N2, and preferably the reference center C, it is possible to further analyze manually or automatically by a computer whether the light intensity of the light emitted by the light source device 2 received by the light sensor exceeds a preset threshold, so as to more accurately determine whether the alignment calibration effect is achieved; wherein, if the light intensity received by all light sensors exceeds the preset threshold, it is determined that the position and angle corresponding to the collimation correction device 1 are consistent with the collimation of the light source device 2 (aligned); otherwise, it is determined that the collimation is inconsistent (not aligned).

[0046] like Figure 2 As shown, at least one of the collimation correction device 1 and the light source device 2 can be arranged on the adjustment device 3, and the adjustment device 3 can be used to adjust the position of the object arranged thereon in the three-axis direction and the angle of the three-axis direction in the three-dimensional coordinate system to achieve the above-mentioned application. The multiple features between the collimation correction device 1 and the light source device 2 form a mechanism for making the collimation correction device 1 and the light source device 2 have consistent collimation. Preferably, the adjustment device 3 can include multiple drivers (not shown) to adjust the position of the three-axis direction and the angle of the three-axis direction. It should be noted that the mechanism / structural configuration that can be used to adjust the position of the three-axis direction and the angle of the three-axis direction is understandable to those with ordinary knowledge in the field, so it is not repeated.

[0047] For example, in an automatically calibrated collimation correction system, the collimation correction system further includes a processor (not shown), the processor is coupled to each of the light sensors and the adjustment device 3 (especially each of the drivers), the processor determines the situation in which each of the light sensors receives the light emitted by the light source device 2, so as to control the adjustment device 3 (especially each of the drivers corresponding to each of the light sensors) to adjust at least one of the three-axial positions and three-axial angles of the light source device or the collimation correction device in the three-dimensional coordinate system, so that the light emitted by the light source device 2 passes through each of the light sensors at the same time. Specifically, corresponding to each of the light sensors, the processor has a corresponding preset threshold; in a case where the processor determines that the light intensity received by one of the light sensors exceeds the corresponding preset threshold, the processor determines that the light emitted by the light source device 2 passes through the light sensor; in a case where the processor determines that the light intensity received by one of the light sensors does not exceed the corresponding preset threshold, the processor determines that the light emitted by the light source device 2 does not pass through the light sensor, and controls the adjustment device 3 to adjust at least one of the three-axial positions and three-axial angles of the light source device 2 or the collimation correction device 1 in the three-dimensional coordinate system, so that the light emitted by the light source device passes through each of the light sensors and is not less than the corresponding preset thresholds.

[0048] According to the configuration relationship between the reference center C, the first alignment point N1 and the second alignment point N2 of the aforementioned collimation correction device 1 (as shown in FIG. Figure 2 ), Figure 5The embodiment of the collimation correction device 1 is shown in which the main body 10 has a first component 11 and a second component 12. The first component 11 has a first component plane P11, and the first component plane P11 has the reference center C and the first alignment point N1, and optionally has an additional second alignment point AN2; in other words, the alignment center plane PC and the first plane P1 coincide with the first component plane P11; that is, the alignment center plane PC, the first plane P1 and the first component plane P11 can be regarded as the same plane. The second component 12 has a second component plane P12 parallel to the first component plane P11, and the second component plane P12 has the second alignment point N2, and optionally has an additional first alignment point AN1; in other words, the second plane P2 coincides with the second component plane P12; that is, the second plane P2 and the second component plane P12 can be regarded as the same plane. Wherein, the first component plane P11 and the second component plane P12 are spaced apart from each other. By the above configuration, in a vertical direction VD perpendicular to the second component plane P12, the reference center C, the first alignment point N1 and the second alignment point N2 do not overlap with each other; specifically, the non-overlapping relationship is in accordance with the aforementioned first alignment point N1 being spaced apart from the first reference reference center C1, the second alignment point N2 being spaced apart from the second reference reference center C2, and the alignment angle θ A Not equal to 0 degrees or 180 degrees and other conditions.

[0049] Optionally, in the configuration having the additional first alignment point AN1 and the additional second alignment point AN2, the reference center C, the first alignment point N1, the second alignment point N2, the additional first alignment point AN1 and the additional second alignment point AN2 do not overlap with each other; in this way, when using the light source device 2 to perform a collimation correction operation, the first line segment light L1 and the second line segment light L2 can pass through the additional first alignment point AN1 and the additional second alignment point AN2 respectively, and then during the manual correction process, it can serve as a visual auxiliary judgment of whether calibration is performed, making the calibration operation easier to perform.

[0050] Specifically, based on Figure 2 , Figure 5 The embodiment shown in the figure can be understood as a configuration in which the alignment center plane PC coincides with the first plane P1, that is, the reference center C and the first alignment point N1 are located in the same plane; with respect to the shape configuration of the collimation correction device 1, at the alignment angle θ AIn the example of 90 degrees, the first component 11 and the second component 12 can form L-shaped rods respectively, and in a vertical direction VD perpendicular to the first or second component plane P11, P12, the first component 11 and the second component 12 are overall configured / assembled in a cross shape.

[0051] Based on the same configuration (ie, the reference center C and the first alignment point N1 are located in the same plane), the collimation correction device 1 can also have the implementation modes as shown in FIGS. 6 and 7. Figure 6 As shown in (Example 2 of the collimation correction device 1), the first component 11 and the second component 12 can form a straight rod; in a vertical direction VD perpendicular to the planes P11 and P12 of the first or second component, the centroid of the straight rod is preferably aligned with the reference center C, and the first component 11 and the second component 12 are configured as a cross as a whole. Figure 7 As shown (Example 3 of the embodiment of the collimation correction device 1), the first component 11 and the second component 12 can also form a straight-line rod respectively; in a vertical direction VD perpendicular to the plane P11, P12 of the first or second component, the reference center C can be located close to one end of the straight-line rod, and the first component 11 and the second component 12 are configured as an L-shape as a whole.

[0052] based on Figure 2 , please refer to Figures 8-9 As shown, another embodiment of the collimation correction device 1 of the present invention, the main body 10 has a first component 11' and a second component 12'. The first component 11' has a first component plane P11', and the first component plane P11' has the reference center C; in other words, the alignment center plane PC coincides with the first component plane P11'. The second component 12' has a second component plane P12' parallel to the first component plane P11', and the second component plane P12' has the first alignment point N1 and the second alignment point N2; in other words, the first plane P1 coincides with the second plane P2 and the second component plane P12'. The first component plane P11' and the second component plane P12' are spaced apart from each other. By the above configuration, in a vertical direction VD perpendicular to the second component plane P12', the reference center C, the first alignment point N1 and the second alignment point N2 do not overlap each other; specifically, the non-overlapping relationship is in accordance with the aforementioned first alignment point N1 being spaced apart from the first reference center C1, the second alignment point N2 being spaced apart from the second reference center C2, and the alignment angle θ AThe angle is not equal to 0 degree or 180 degree. In a specific example, the first component 11' may be a triangular reflector, and the second component 12' may be a cross-shaped rod. In addition, the present invention is not limited thereto.

[0053] It should be noted that the above Figure 5-9 The various embodiments are only for more clearly explaining various feasible implementation examples based on the characteristic relationship (configuration relationship between the reference center C, the first alignment point N1 and the second alignment point N2) of the collimation correction device 1 of the present invention; therefore, under the condition of satisfying the defined characteristic relationship, the collimation correction device 1 of the present invention is not limited to the aforementioned implementation examples. In particular, another feasible embodiment of the present invention certainly includes an implementation example in which the reference center C, the first alignment point N1 and the second alignment point N2 are all located in different planes.

[0054] In summary, the collimation correction device and its method and system of the present invention, through the specific configuration relationship between the reference center, the first alignment point and the second alignment point, make the corresponding correction method and system easier to implement. In addition, through the above-mentioned collimation correction device, in the subsequent collimation correction operation, only a single light source device can be used to calibrate the collimation, so as to avoid the situation of multiple cumulative errors caused by using multiple light source devices, and the accuracy and reliability of the collimation correction can be improved. In addition, through the above-mentioned collimation correction device, the light source device can be independently arranged outside the body of the collimation correction device to simplify the connection relationship between the devices and make the hardware configuration of the correction operation simpler. In addition, through the connection and mutual operation relationship between the collimation correction device, the light source device, the adjustment device, the light sensor and the processor, the collimation correction operation can be automatically performed, and the accuracy and reliability of the correction can be improved.

Any person skilled in the art can make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the technical scope protected by the present invention is still within the scope of the present invention. Therefore, the protection scope of the present invention should include all changes within the meaning and equivalent scope of the attached patent application.
