[0036] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0037] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0038] Please also see Figure 1 and Figure 2 As shown, the multi-directional laser-assisted positioning system provided by an embodiment of the present invention is now described.

[0039] The multi-directional laser-assisted positioning system includes: multiple laser positioning mechanisms and a controller.

[0040] The laser positioning mechanism is distributed at different positions of the object to be processed and assembled, and is used to emit multiple laser auxiliary lines from different positions to the object to be processed and assembled for positioning. Figure 1 As shown, the number of laser positioning mechanisms can be set to 6, and the 6 laser positioning mechanisms are respectively distributed in the front, back, left, right, top and bottom six directions of the object to be processed and assembled. According to the processing requirements of the object to be processed and assembled, the number of laser positioning mechanisms can also be less or more. For example, when the object to be processed and assembled only needs to be positioned from the front and back directions, the number of laser positioning mechanisms can be two, which are respectively set in the front and back directions of the object to be processed and assembled. Alternatively, when the length of the object to be processed and assembled is long, the number of laser positioning mechanisms can be increased, for example, two or more laser positioning mechanisms can be used in one direction.

[0041] See also Figure 2 As shown, in this embodiment, the laser positioning mechanism includes a laser level 21 and a mechanical moving device 22. The laser level 21 is installed on the mechanical moving device 22, and the mechanical moving device 22 is driven by the first motor inside it to drive the laser level 21 to move. The controller connects the laser level 21 and the mechanical moving device 22 to control the movement of the positioning line and the mechanical moving device 22. Optionally, a high-precision electric rotating workbench 23 can be provided on the mechanical moving device 22. The laser level 21 can be installed on the high-precision electric rotating workbench 23, and the high-precision electric rotating workbench 23 is driven by the second motor to drive the laser level 21 to rotate. In this embodiment, the laser positioning mechanism mainly sets the front, back, left and right directions with a rotation function, and adopts a high-precision electric rotating workbench to control the laser level in the four directions of front, back, left and right to rotate 360°, thereby having the function of accurately positioning the angle line.

[0042] Here, the controller can be a PLC and a servo driver with a 16-axis drive function, which is responsible for driving the movement of each mechanical moving device 22 and the rotation of the high-precision electric rotary table 23. The mechanical moving device 22 is driven by a synchronous belt 24, and the synchronous belt structure has the characteristics of simple structure, precise transmission, light weight, and easy disassembly and assembly. The first motor and the second motor can be a servo or a servo motor. The mechanical and electrical structures of each laser positioning mechanism are independent, but are controlled by the same controller through the connection of control cables. Removing the control cable connection of any laser positioning mechanism does not affect the use of other laser positioning mechanisms, so the entire system has good scalability and adaptability. Each laser positioning mechanism is light in weight, and the connection and matching structure is easy to disassemble and assemble, and it is convenient to disassemble and relocate.

[0043] The controller can be connected to the host computer, and the host computer is provided with a touch screen, for example, the host computer can be a computer equipped with configuration software. The staff can set the distance value that the mechanical moving device 22 needs to move in each direction through the touch screen, and the PLC controls the mechanical moving device 22 to move the laser level 21. According to the work needs, the installed laser level 21 is controlled to emit multiple directional light rays, and the light rays are displayed on the object to be positioned. The touch screen can also be used to set the tilt angle that the laser level 21 needs to rotate in the four directions of front, back, left and right. The PLC controls the high-precision electric rotating workbench 23 to drive the laser level 21 to rotate. According to the work needs, the installed laser level 21 emits directional light rays, and the angle line light rays are displayed on the object to be positioned. The angle and length can be positioned quickly and efficiently according to the light rays. The positioning accuracy can reach plus or minus 1mm within 10m, and the angle line accuracy is 0.1°.

[0044] The embodiment of the present invention uses multiple laser levels to emit laser auxiliary lines from different directions to the objects to be processed and assembled, so as to realize three-dimensional auxiliary positioning of the objects to be processed and assembled. The laser level is installed on a mechanical moving device, and a controller is connected to the mechanical moving device. The controller can control the mechanical moving device to drive the laser level to move, so as to realize precise adjustment of the positioning line. Compared with the traditional manual measurement and marking method, this system can more conveniently assist in positioning the workpiece and improve the processing and assembly efficiency.

[0045] Optionally, the laser positioning mechanism can be fixed on a fixed base (such as a small hydraulic platform) to expand its measuring height and facilitate work. The laser positioning mechanism is installed in a magnetic installation manner, that is, an iron plate is installed on the fixed base, and there are stainless steel plate stops on three sides of the iron plate (to ensure good contact with the iron plate and limit movement). A permanent magnet (the same size as the iron plate installed on the fixed base) is installed at the bottom of the laser positioning mechanism. When in use, it is directly attracted to the iron plate for easy installation and removal.

[0046] Optionally, the multi-directional laser-assisted positioning system also includes: a remote control device; the remote control device is wirelessly connected to the controller.

[0047] In this embodiment, a manual remote control function is designed. The remote control is selected by an electrical switch. The remote control device can be used to control the movement and rotation of the laser positioning mechanism in each direction (limited to the laser positioning mechanism in the four directions of front, back, left, and right), which is convenient for operating each laser positioning mechanism at various locations on site. The position value and tilt angle value of the laser positioning mechanism in each direction are displayed in real time on the touch screen. Through laser light positioning, the purpose of reducing tool measurement and improving positioning accuracy is achieved. The remote control device here can be a dedicated remote control, a mobile phone, etc.

[0048] Optionally, the laser level 21 can be a 12-line model (the number of lines of the laser level is not limited in this application and can be selected according to the working conditions. A simple laser line marker can also be used), with a working distance of about 25 meters. The emitted light can form three planes: up and down, left and right, and front and back. Each laser level 21 can move in the horizontal, longitudinal and vertical directions; the six laser levels 21 are basically the same and have the same positioning accuracy. The positioning accuracy of the six sets of laser positioning mechanisms is at the millimeter level.

[0049] Before performing positioning work, staff can use the touch screen to set system parameters, perform positioning control, calibrate and other functions.

[0050] System parameter setting: The controller obtains the parameter setting instruction of the laser positioning mechanism; according to the parameter setting instruction, the initial parameters of the laser positioning mechanism are set.

[0051] Here, the initial parameters may include the initial position of the laser positioning mechanism, the moving speed, etc. For example, the staff can set the moving speed of each axis on the touch display screen as needed to improve the positioning efficiency.

[0052] Positioning control: The controller obtains the positioning control instruction of the laser positioning mechanism; according to the positioning control instruction, the laser positioning mechanism is positioned and controlled.

[0053] In this embodiment, for the object to be processed and assembled, six laser positioning mechanisms are distributed in different directions (up, down, left, right, front, and back), and the operator performs positioning and other tasks according to the emitted light. The operator can set the movement values ​​of the laser positioning mechanisms in each direction on a touch screen, and the system drives the laser positioning mechanisms in each direction to move according to the requirements of each value, so that the light emitted by the laser level 21 installed on the laser positioning mechanism reaches the set value position, and the position value of the laser positioning mechanism in each direction is displayed on the touch screen. The operator can also use a remote control to control the movement of the laser positioning mechanism in each direction.

[0054] Calibration: The controller obtains the calibration instruction of the laser positioning mechanism; according to the calibration instruction, the laser positioning mechanism is calibrated.

[0055] In this embodiment, the laser level has 12 lines, and one laser level can realize the positioning of three planes. The controller uses any one laser level among the multiple laser positioning mechanisms as a reference, and the controller performs calibration by controlling the movement of the remaining laser positioning mechanisms.

[0056] Optionally, taking any one of the laser level meters in the plurality of laser positioning mechanisms as a reference, calibrating the laser level meters in the remaining laser positioning mechanisms includes:

[0057] According to the relative position relationship between the remaining laser level instruments and the laser level instrument, the target light is determined from the horizontal light rays and the vertical light rays of the remaining laser level instruments;

[0058] Control the mechanical moving devices of the remaining laser levels to move so that the target light beams of the remaining laser levels overlap with the corresponding light beam of the laser level to obtain an origin coordinate of each laser level;

[0059] According to the relative position relationship of each laser level, the coordinates of another origin of each laser level are determined to realize the calibration of the laser level.

[0060] by Figure 1 Take the 6 laser positioning mechanisms shown in the figure as an example. The 4 laser positioning mechanisms in the front, back, left, and right directions have both movement and rotation functions, while the 2 laser positioning mechanisms in the top and bottom directions only have movement functions. Figure 3 As shown. Through the same control system (touch screen, PLC and servo drive), 6 directions (up, down, left, right, front and back) and 2 axes in each direction (horizontal or longitudinal, and vertical direction) control + 4 directions of rotation are operated, and the 6 directions can be calibrated and adjusted to achieve the same plane reference for the laser level in the 6 directions, and have the function of positioning the angle line (oblique line), thereby greatly improving the efficiency and accuracy of mechanical positioning, assembly and detection errors, especially suitable for the production and installation of large equipment, tooling and devices.

[0061] The calibration process is as follows:

[0062] (1) The laser level in the five directions of front, back, left, right and bottom uses the horizontal direction and any vertical direction to locate and calibrate the origin. The best is to use the horizontal and vertical direction light of the laser level below as the reference, and overlap the horizontal light and any vertical light of the other four laser levels with it respectively. After overlapping, the height position is set as the Z-axis origin of the five laser levels. Because any light of the selected laser level is part of its plane light, the plane positioning is achieved through light positioning, so that the three planes of the selected laser level are perpendicular to each other, thereby achieving the mutual perpendicular positioning of the three planes. The X-axis (for the front and back two laser levels, the X-axis is the left and right direction; for the left and right two laser levels, the X-axis is the front and back direction) reasonably sets the origin (the laser origin settings of the front and back directions are consistent; the origin settings of the left and right directions are consistent, which means that the direction and position values ​​are the same). In this embodiment, any laser level can be used as the reference for origin positioning and calibration. Using the laser level below as the reference for origin positioning and calibration is the fastest and has the smallest operation error.

[0063] (2) The upper laser level is calibrated in the vertical direction, that is, the vertical light is overlapped with the vertical light of the lower laser level, and the position of this point is set as the X-axis origin; the Z-axis origin directions of the lasers in the upper and lower directions are set to be consistent (up and down movement direction).

[0064] Through the above light positioning operation, the six laser positioning mechanisms can achieve the consistency of all related plane positioning references (that is, the horizontal planes of all laser positioning mechanisms are parallel, and all vertical planes of the vertical direction are parallel). Therefore, the system can determine the positions of multiple planes and multiple points on the object to be processed and assembled, and the multiple plane references are consistent.

[0065] This embodiment uses a multi-directional laser assisted positioning system to emit multiple rays, which are displayed on the object to be processed or assembled, and can improve the positioning speed and accuracy of mechanical processing and mechanical assembly; through electrical control, the laser rays of the laser positioning mechanism in each direction can be automatically and accurately moved according to the set direction and value; the movement of the laser positioning mechanism in each direction can be manually controlled by the remote control device; the touch screen displays the position values ​​of the laser positioning mechanism in the horizontal and vertical directions in real time in each direction, thereby improving the efficiency of positioning. Using the multi-directional laser assisted positioning system proposed in this embodiment, in actual applications, the lower side door welding production line uses a one-line laser marking instrument to assist in assembly positioning and welding track irradiation; the steel pretreatment line uses a one-line laser marking instrument for distance prediction; the plasma cutting machine uses a cross laser marking instrument for edge finding and positioning: the new energy flip car tooling production uses a 12-line laser level to assist in positioning and detection.
