1263110 V. INSTRUCTIONS (2) [Summary of the Invention]

In the inventor's prior patent "Automatic Laser Pointing Instrument" (Patent Certificate No.: 1 5 9 1 6 6), it has been described that a beamlet is emitted from a laser module and expanded into a planar thin beam by a beam expander. When the beam expander is a cylindrical mirror, the beam is fan-shaped; when the beam expander is a cone mirror, the beam is a 360-degree optical full plane. In addition to the unpowered beam expanders described in the above patents, powered beam expanders can also be used. The thin beam emitted from the laser module is reflected by a mirror driven by a motor to form a scanning plane. The mirror may be parallel to the axis of rotation of the motor, in which case the incident light should be perpendicular to the axis. The mirror may also be at 45 degrees to the axis of rotation of the motor, where the incident light should be parallel to the axis. Their direction of movement in the target plane coincides with the direction of motor rotation. When the motor rotates very quickly, the observer sees the line in the S level S - straight line -

The above motors can be replaced by vibrating motors, and their spots in the target plane will move back and forth. When the vibration frequency is high, the observer sees a straight line in the target plane. When a planar thin beam is rotated about an axis, the projected line of the rotating planar thin beam moves in the target plane. In order for the projection line in the target plane to move in parallel during rotation, the axis of rotation should be parallel to the target plane. In order to keep the projection line in the target plane horizontal during the rotation, the shaft needs to be at

Page 6 1263110 V. Description of invention (3) Horizontal status. The parallelism of the axis of rotation to the target plane is determined by a parallel inspection device. The parallel detecting means may be two ultrasonic or optical wave distance measuring devices placed at different positions in the direction of the rotating shaft. They respectively emit pulse waves to the target plane; the parallelism between them is determined by measuring the time that the return waves reach their respective detectors. The parallel detection device can also place two graphic projectors at different positions in the direction of the rotation axis, and compare the projections of the graphics they emit on the target plane to determine their parallelism. The graphic projector can be a thin beam tapered optical element. A cone-shaped thin beam of light can be generated by directing the element along the axis of symmetry of the tapered optical element. The beam projects an ellipse in a plane that does not resemble its axis. Obviously, two identical tapered thin beams formed by the same two sets of tapered optical elements are respectively projected onto the target plane, and if they are the same size and shape in this plane, the connection between the cone tops Parallel to the target plane. For ease of

1263110 V. Description of invention (4) Distance. The beam generated above is a thin cone beam. It can also be a solid cone beam. For ease of comparison, the two beams of light can have different colors. When the two beams coincide in the target plane, the color of the two projections is the sum of the two colors. If the two solid cone beams are red and green, respectively, as long as the entire projection (ellipse) in the target plane is a single yellow, the line between their cones is parallel to the target plane. Two sets of optical elements capable of producing an astigmatic beam are another parallel detecting device of the present invention. The so-called astigmatic beam refers to a beam that is inconsistent in two mutually perpendicular directions. The beam at this focus is a short line called the focal line that is perpendicular to each other. The load surface at a position between the two focal lines is circular. Another parallel detection device is constructed using two sets of identical optical elements that produce an astigmatic beam. First, two identical astigmatic beams are projected onto the target plane. When they produce the same two figures in the target plane, such as a circle or a focal line in the same direction, the direction of the plane can be determined. Of course, the projected beam can also have other geometric shapes, such as a fan beam. It is a straight line in the target plane. Is the graphic projector in another parallel detection device of the present invention capable? Two sets of devices that cross the light. Two beams of cross light are directed at the target plane; the target plane is recombined only when it is at their intersection. Otherwise in peace

1263110 V. Description of invention (5)

Two points appear on the surface, and the further away from the intersection, the greater the distance between them. The intersection of the two sets of crossed lights is set parallel to the axis of rotation of the optical plane. As long as more than two spots appear on the target plane, the axis of rotation is not parallel to the plane. The parallelism of the target planes at different distances can be determined by optically moving the positions of the two intersecting spots in parallel. The simplest way to form two sets of crossed light is to use four sets of laser modules that form a beamlet. The two groups form a set of intersecting lights, and the intersections of the two sets of crossed lights are parallel to the axis of rotation. This parallel measurement can also be flexibly implemented in a specific optical design using different optical methods and optical components. Since the angle of intersection of the two intersecting beams with the axis of rotation can be determined, this device can be used simultaneously to determine the distance to the target plane. The horizontal state of the projection line is measured by a level detecting device. It can be a long blisters placed along the horizontal projection line.

With the above beam expander and level detecting means and parallel detecting means, the present invention has completed a simple horizontal line generator, and the present invention will be described in detail in conjunction with the drawings. The invention utilizes a cylindrical mirror or a conical mirror as a beam expander to expand the fine light emitted by the laser module into a fan-shaped or full-plane thin beam; and then the thin beam is horizontally and parallel to the target plane. The axis rotates, and horizontal lines of different heights are formed in the target plane. In such a work

Page 9 1263110 V. INSTRUCTIONS (6) The horizontal line projected by the horizontal line generator developed on the basis of the change does not have to be horizontally moved in the vertical direction when the height is changed. The horizontal state of the rotating shaft can be achieved with a blisters adjustment device. Conveniently, a simple and reliable parallel measurement method is an important part of the present invention. The effects of the present invention are: 1. A simple method of inventing a laser horizontal line to a target without changing the height of the projection device.

2. A fast, reliable, and accurate method of inventing the axis of the optical plane in a direction parallel to the target plane. 3. Use this method to design a horizontal line generator with simple and compact structure, low power consumption, excellent performance and low price.

In order to enable the reviewing committee to further understand the present invention, and to enable the same skilled person (( ers ο nski 1 1 edi η 1: hcfic 1 d ) to be implemented in accordance with the specification and embodiments of the present invention, A preferred embodiment of the present invention is disclosed as follows, and the basic spirit and appropriate teachings of the present invention are disclosed to enable those skilled in the art to practice the invention. In the following, a preferred embodiment will be described in detail with reference to the drawings and drawings, and the components of the present invention and the functions thereof are described in detail as follows: [Embodiment] The beam expander 10 used in the present invention is as a first The figure shows. It contains

Page 10 1263110 V. INSTRUCTIONS (7) A laser module that produces a beam of light. The thin beam emitted by it is a beam expanding optical element, in the figure a cylindrical mirror 12, which is developed in one direction into a fan beam FB which projects a straight line L on the target plane V. Referring to Figure 1 a, when the beam expander 10 is rotated about the Z-Z axis, a straight line L is projected on the target plane v to move. The first b-picture shows that a reflective optical element 13 is placed on the fan-shaped beam from the beam expander 10, which can change the direction of the fan-shaped beam and project a straight line L on the target plane V. The reflective optical element 13 is rotated about the Z-Z axis, and the straight line L projected on the target plane 也 also moves. The beam expander 10 of the first and second figures can be driven by power. The reflex and j elements in the first a diagram are a plurality of S bodies 15 composed of a plurality of reflecting surfaces 15a, 15b, 15c, ... which are parallel to the rotation axis of the motor 14. The beamlet emitted from the laser module 11 is directed perpendicularly to the axis of rotation of the motor 14 to the multi-reflecting surface body 15 . It is reflected by the reflection surfaces 15 5a, 15b, 15c··· driven by the motor, and a plane SB is scanned. The direction of movement of the reflected light in the target plane v coincides with the direction of rotation of the motor 14. When the motor 14 rotates very quickly, the observer sees a straight line L in the target plane v. The reflective element in the second b-picture is a polyhedron 16. It consists of a plurality of reflecting surfaces 16a, 16b, and 16c, which are at a distance of 45 degrees from the axis of rotation of the motor 14. From the laser

1263110 V. INSTRUCTIONS (8) The module 1 1 emits a beamlet pointing in the direction of the motor in the direction of rotation of the motor to the 45-degree polyhedron 1 6 which is driven by the motor 14 to the reflecting surface 1 6 a, 1 6 b, 1 6 c ...reflecting, a plane SB is scanned. In order to make it known as a plane? Strict plane, the degree of reflector can be replaced by a 45 degree mirror 1 7 (second c picture). At this time, a beamlet is emitted from the laser module 11 and directed to the 45-degree single mirror along the axis of rotation of the motor 14 with a scanning surface covering a full 360 degree range. The I:8 and the third b-picture show that the mirrors of the actuators that are driven by the driver 18 are flat one expanders. The mirror 19 in the third a diagram is perpendicular to the rotation of the driver 18. The beamlet and the rotation of the motor 14 are emitted from the laser module 11 by a light spot: a side mirror 19. After the beamlet is reflected, it is seen in the target plane. When the vibration frequency is high, the observer is at 5 degrees in the target plane; the line L. The reflective element in the third b-figure is coupled to the drive shaft as a rotary shaft to the mirror 17. From the laser module 11, a beamlet is emitted along the rotation of the motor 18 L / ° the mirror 17 . After it is reflected, it forms in the target plane as shown in Fig. a and Fig. 4b. It shows how to generate a low horizontal line c plane V flat/figure, assuming that the Z z axis is in the horizontal plane and The light that does not level with the target is continued. When the fan beam is rotated around the Ζ Ζ axis, it is projected on the target plane V. The high sounds L, L1, L2, ... are not parallel to each other. Therefore, it cannot produce a horizontal line with the target g =. The fourth b diagram assumes that the Ζ-Ζ axis is in the horizontal plane 且 and is incident on the surface V parallel. When the fan beam FB rotates around the Ζ-Ζ axis, the plane V rays L, LI, L2··· will be parallel to each other. At this time, it produces

Page 12 1263110 V. INSTRUCTIONS (9) The horizontal lines of different heights are produced. The fourth c-picture illustrates the case where the Z-Z axis is parallel to the target plane V but not at the target plane II. The lines L, L 1 and L 2 of different heights generated at this time are parallel to each other, but are not horizontal lines. The fourth c-figure shows that in order to produce horizontal lines of different heights, the axis Z - Z of the flat optical surface must be parallel to the target plane V, and the line it projects must be corrected to the level. In order to make the axis Z - Z have to be parallel to the target plane V, the present invention uses a parallel detecting device. Referring to the fifth figure, two ultrasonic waves 2 or a light wave distance measuring device 2 2 are placed at different positions along the Z-Z direction of the rotating shaft. They respectively emit pulse waves to the target plane V, and the parallelism between them is determined by measuring the time at which the return waves reach their respective detectors. The first projection beam of the present invention is a conical beam. It can be a thin beam or a solid beam. As shown in the sixth figure, a tapered optical element 30 which can produce a conical thin beam is used. Figure 6a is a reflective tapered optical element 30, a symmetrical cone 3 2 system that rotates along its axis of symmetry 36. Reflective surface. The incident light T B is incident on the tapered surface 3 2 along the weigh axis 36, and is reflected to form a cone beam C B . The cone apex angle of the cone beam is determined by the cone apex angle of the cone mirror. The sixth b-figure is a refractive cone type optical element 35 which is an optically transparent body. A symmetrical tapered surface 38 that rotates along its symmetry axis 36 is a refractive surface, and a conical bottom surface 37 that is perpendicular to the symmetry axis 36 is an optical plane. The incident light T B is directed across the conical bottom surface 37 along the axis toward the symmetric tapered surface 38. Refraction through the symmetrical cone 3 8 into the space to form a cone

1263110 V. Invention Description (ίο) Shape beam CB. Depending on the geometry of the cone, the beam TB draws a circle in the plane of projection perpendicular to its axis of rotational symmetry 36. When the target plane is not perpendicular to the axis and is not parallel to the symmetry cone 38 or the symmetry axis 36, the beam C B draws an ellipse within the projection plane. The device 40 of the seventh figure can be replaced by a solid cone beam. The light emitted from the point light source 4 1 is the optical system 42, and after focusing, a solid cone type beam CB is formed through the small holes 43. Depending on the geometry of the cone, the cone beam TB draws a circle in the target plane perpendicular to its axis of symmetry 44. When the target plane is not perpendicular to the axis and is not parallel to the cone or axis, the beam CB draws an ellipse in this plane. Another projection beam of the present invention is an astigmatic beam, as shown in the eighth diagram for the projection characteristics of an astigmatic beam. The astigmatic beam is focused at different positions F X and F y in two mutually perpendicular directions X-X and y - y, respectively. Due to the spreadability of the beam, there are two mutually perpendicular short lines 4 6 and 4 8 , which are referred to as focal lines ◦ at a position F between the two focal lines 46 and 48 which is circular 47 ° in cross section. Two beams of the same light are directed toward the target plane, which respectively form two patterns on the plane. Comparing the shape and size of the two graphs determines the parallelism between the optical plane axis and the target plane.

1263110 V. INSTRUCTION DESCRIPTION (11) The parallel detection device of Figure 9a contains two sets of identical conical projection generators. They produce two cone-shaped lights C B 1 and C B 2 with cone tops at 5 1 and 5 2 respectively. The ninth a diagram is a case where the target plane V is parallel to the two cone top lines 5 3 . At this time, the tapered lights CB1 and CB2 respectively draw two identical graphic ellipses 5 5 and 5 6 . When the axes of symmetry of the two beams are parallel, they are two identical circles in the target plane v. When the axes of symmetry of the two beams are not parallel, they are two identical ellipses in the target plane v. To make it easier to compare the two geometric ellipses 5 5 and ellipse 5 6 in the target plane V, we make the two identical ellipses in the target plane V coincide (ninth b). In the ninth c-figure, the target plane V and the two-cone top line 53 are not parallel. At this time, the tapered lights CB1 and CB2 respectively draw two circles or ellipticals 5 5 and 5 6 of different sizes. Therefore, comparing the two projections on the target plane V can be used to determine whether the S-level S V and the chrome-top connection 5 3 are OK. When the position of the target plane changes, we can simultaneously rotate the cone-shaped lights C B 1 and C B 2 symmetrically so that they coincide with the two geometrical ellipses 5 5 and ellipses 56 in the target plane V. Further, the rotation angle α can be simultaneously detected when the tapered light beams C B 1 and C B 2 are rotated. This parallel detecting device can also measure the distance from the cone top line 5 3 to the target plane V (=1 / 2 two cone top distance t a η α ). When the cone beam used in the fifth figure is the real cone beam produced by the device 40 of the seventh figure, the two beams of light may be of different colors. When the entire projection is two

Page 15 1263110 V. Inventive Note (12) When the sum of colors is used, the direction of the plane is determined, for example, the two solid cone beams are red and green, respectively. In this way, their superposition is yellow. When the ellipse of the entire projection in the target plane is yellow, the direction of the plane is a determined parallel direction. When not parallel, in the ninth c-graph, only the area where the graphic ellipse 5 5 and the ellipse 56 coincide, is the sum of the two sums, the areas that are not coincident? Original beam color. The tapered light CB1 and CB2 used in the ninth a diagram can be replaced by a astigmatic light beam. When the optical axes of the two astigmatic beams are parallel, the beams are in the same circular or co-directional focal line in the target plane, and the parallelism between the target plane V and the plane of the optical plane can be determined. Another parallel detection device of the present invention utilizes two sets of intersecting rays to determine parallelism, and the tenth figure is used herein to illustrate the operation of the cross beam. The two bundles of fine rays 6 1 and 6 2 intersect at point P. When the target plane appears at the intersection V〇, a bright spot appears on the plane. When the target plane V appears before the intersection V 1 , two bright spots 6 3 and 6 4 appear in the plane. When the target plane V appears at V 2 after the intersection, two bright spots 6 5 and 6 6 appear in the plane. In Fig. 11a, the parallelism of the target plane is confirmed by using the light rays 7 2 and 7 3 at the intersection of 7 1 and the light rays 8 2 and 8 3 at the intersection of 8 1 . Dijon - In the figure, the intersections 71 and 81 of the ray are fixed in the plane V parallel to the line Χ-Χ. The eleventh b diagram shows that the XX axis is not parallel to the target plane v, at this time in the target plane. Three or more spots appear in V. Figure

INSTRUCTIONS (14) Synchronously rotating half mirror 11 1 and half mirror 1 1 3 or/and synchronous rotating half mirror 1 1 2 and mirror 1 1 4 intersecting light spots 7 1 and 8 1 Will move. In Fig. 8, only the half mirror 1 1 1 and the half mirror 1 1 3 are shown to be rotatable about the axes 1 16 and 1 18 respectively. The thirteenth pattern is a parallel measuring device using two lasers. Its splitting circle is a prism 120. It has two planes 121 and 123 and two slopes 1 2 2 . The fine light B from the laser modules 1 0 1 and 1 〇 3 is respectively incident on the intersection of the inclined surface 122 of the prism 1 2 0 and the plane 123. A portion of the beam passes through plane 123 to form beams 72 and 83. The other part is a slope ία refracting to form beams 73 and 83. Beams 72 and 73 are crossed at point 71 by beams 71 and 83 at point 81. Rotating the lasers in the opposite direction can translate their intersections. In combination with the laser light spreader of the present invention and the parallel measuring device for the planar light axis relative to the target plane, the present invention designs a simple horizontal line projecting device of Figures 14a and b. The device has a rotatable upper half 2 2 〇 and a base 2 1 0. They are connected by a hinge 210 and the upper half 2 2 转动 is rotatable about the Z-Z axis determined by the hinge 201. The upper half 220 is provided with a beam expander 221. It emits a plane of light FB parallel to the z-z axis. It also holds a long blisters 222 parallel to the axis z-2 axis and a blisters 2 2 3 placed substantially perpendicular to the blisters 2 2 2 . The direction of the light plane is adjusted by three adjustment screws 2 0 2a, 2 0 2 b and 2 0 2 c on the bottom surface of the base 2 10 0 which are not in a straight line. Blisters when the light plane FB is a horizontal plane

1263110 V. INSTRUCTIONS (15) 2 2 2 and 2 2 3 are all in the blisters. From the mirror 21 2 (the beam 7 2 and the rotation axis of the intersection point are fixed, the rotation direction of the tooth direction is different, and the cross-light principle can be used. The fourteenth c-c is another thinning of the original laser module 1 〇1. The light beams transmitted through the half mirrors 2 n are reflected and reflected from them, respectively, through the beam splitters 2 1 3 and 2 1 4 into light 83; the light reflected therefrom becomes beams 73 and 82. The beams 72 and 73 merge at 71; 82 and 83 meet at intersection 81. Planar beam ZZ is parallel to ray intersections 71 and 72. Beamsplitters 21 3 and 21 4 are split between two intermeshing gears 2 1 5 and 2 16 . The wheel 217 rotates. The gear 217 rotates and pushes the opposite ends of the gears 215 and 216 to cause movement of the intersection. Thus, the device can measure the parallelism of the target plane over the distance. This parallelism measuring device is placed in the base. The angle of rotation of 2 1 8 can be determined and the distance between the two beamsplitters 2丨3 and 2 i 4 is fixed. Therefore, the distance between the device and the target plane can be measured. This distance depends on the angle of rotation of the adjusting wheel 218. Therefore, it is possible to correspond to the corner The distance is placed on the dial outside the adjustment wheel 2 1 8 . The mechanical device utilized by the horizontal line projection device is invented, such as the selection of the optical component in the parallel measurement system of the water σ circumference device and its division 1 The mechanical devices and specific combinations involved are very easy for people who have the skills of native mechanical design.
