[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0032] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
[0033] In some embodiments, a large micron-level high-precision walking scanning device for detecting satellites is provided. The scanning device is mainly used for horizontal scanning of the near-field XY axis scanning frame, and the scanning frame is moved according to the test requirements, which can meet the requirements of related control to achieve 8-meter long horizontal scanning repeat positioning accuracy of 10 microns, and 1-meter vertical scanning repeat positioning accuracy of 7 microns. It solves the problem that similar products were previously all made in the United States, with high import purchase costs, high labor costs, and high maintenance costs.
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the large-scale micron-level high-precision walking scanning device mainly includes a gantry 10, an X-axis walking module 20, a Y-axis walking module 30, a Mass axis counterweight module 50, an Xfin axis module 40, a Z-axis walking module 60, a polarization axis rotation module 70 and a scanning probe 80. The X-axis walking module 20, the Y-axis walking module 30 and the Z-axis walking module 60 can respectively control the scanning probe 80 to perform operation adjustment in the X-direction, the Y-direction and the Z-direction to achieve the coarseness adjustment of the scanning device.
[0035] Specifically, the Y-axis walking module 30 is longitudinally installed on the top of the gantry 10 through the transversely arranged X-axis walking module 20, and the transversely arranged Xfin axis module 50 is installed on its slider. The moving stroke of the X-axis walking module 20 and the Y-axis walking module 30 determines the scanning detection range of the scanning device. According to needs, the coverage scanning detection range based on the X-axis walking module 20 and the Y-axis walking module 30 can reach 8000mm×8000mm.
[0036] In order to realize high-precision, high-intelligence and high-reliability control of the scanning device, Figure 3 and Figure 5 As shown, the scanning device is additionally provided with a Mass axis counterweight module 50 and an Xfin axis module 40. The Mass axis counterweight module 50 is installed at one end of the Xfin axis module 40, and the vertically arranged Z axis walking module 60 is installed at the other end to improve the redundancy and reliability of the system.
[0037] To achieve 360° detection scanning without blind spots of the scanning probe 80, Figure 1 and Figure 4 As shown, the polarization axis rotation module 70 is installed on the slider of the Z-axis walking module 60. The polarization axis rotation module 70 is vertically arranged up and down, and the scanning probe 80 is installed on the rotation axis at the lower end.
[0038] In some of the embodiments, Figure 1 and Figure 2 As shown, the gantry 10 serves as the mounting base of the scanning device, and mainly includes a support frame body 11, an X-axis main beam 12, and a Y-axis main beam 13. The support frame body 11 is a horizontal gantry structure constructed of a steel structure; the X-axis main beam 12 and the Y-axis main beam 13 are fixedly mounted on the top of the support frame body 11 by a fixing block 121.
[0039] The X-axis main beam 12 is installed horizontally on the top of the support frame body 11, and the X-axis walking module 20 is installed on it along the length direction. The Y-axis main beam 13 arranged longitudinally is fixedly installed on the slider of the X-axis walking module 20, and the Y-axis walking module 30 is installed on the Y-axis main beam 13 along its length direction.
[0040] As a preferred embodiment, in order to ensure the stability of the operation of the scanning device, there are two X-axis main beams 12, which are respectively installed in parallel at the top positions of the left and right sides of the support frame body 11, and the X-axis walking module 20 is installed on each X-axis main beam 12. There is one Y-axis main beam 13, which is installed on the sliders of the left and right X-axis main beams 12 through its two ends.
[0041] In addition, if Figure 2 As shown, in order to facilitate the installation and maintenance of the scanning device, the gantry 10 also includes a climbing escalator 14 and an artificial passage 15. The climbing escalator 14 is installed on the outer wall of the support frame body 11; the artificial passage 15 is longitudinally installed on the upper part of the support frame body 11, and one end of the artificial passage 15 is connected to the climbing escalator 14.
[0042] When the equipment needs to be inspected and maintained, the scanning equipment is controlled to move to the position of the artificial channel 15, and then the maintenance personnel enter the upper artificial channel 15 from the escalator 14 to facilitate regular maintenance of the Mass axis counterweight module 50, Xfin axis module 40, Z axis walking module 60, polarization axis rotation module 70 and scanning probe 80.
[0043] In some of the embodiments, Figure 1 As shown, corresponding to the two groups of X-axis main beams 12 arranged in parallel on the left and right sides, the X-axis walking modules 20 are two groups, which are horizontally installed on the X-axis main beams 12 at the top of the left and right ends of the gantry 10.
[0044] Correspondingly, the Y-axis walking module 30 is a group, and its two ends are respectively fixedly mounted on the sliders of the left and right X-axis walking modules 20, forming a cross-arrangement installation method, so as to facilitate the control of the scanning probe 80 to accurately scan the travel area formed by the left and right X-axis walking modules 20 and the Y-axis walking module 30.
[0045] In addition, in order to achieve accurate positioning of the moving positions of the X-axis walking module 20 and the Y-axis walking module 30, an X-axis grating ruler 21 is installed along the length direction of the X-axis walking module 20, and a Y-axis grating ruler 31 is installed along the length direction of the Y-axis walking module 30. The moving positions of the X-axis walking module 20 and the Y-axis walking module 30 are monitored in real time by the X-axis grating ruler 21 and the Y-axis grating ruler 31, so as to achieve coarse positioning of the scanning probe 80.
[0046] In some embodiments, each travel moving module can adopt different types and specifications as needed. As shown in the figure, the X-axis walking module 20 and the Y-axis walking module 30 are arranged vertically on the horizontal plane, and both use dual-motor servo modules; the Z-axis walking module 60 uses a single-motor servo module.
[0047] In some of the embodiments, Figure 3 , Figure 5 and Figure 6 As shown, the Mass axis counterweight module 50 adopts a high-precision servo slide module, and a counterweight block 51 is installed on the slide. By controlling the counterweight block 51 to move forward and backward, the gravity balance at both ends of the Xfin axis module 40 is adjusted to balance the horizontal accuracy of the Z-axis walking module 60. The Xfin axis module 40 adopts a high-precision motor to load the Z-axis walking module 60 for fine-tuning the repeatability positioning accuracy of the X-axis movement.
[0048] The Xfin axis module 40 adopts a high-precision servo slide module, and a stabilizing lever 41 is installed horizontally on the slide. The Mass axis counterweight module 50 is installed at one end of the stabilizing lever 41, and the Z axis travel module 60 is installed at the other end. Since the Z axis travel module 60 will cause the gravity imbalance at both ends of the stabilizing lever 41 during the up and down movement, the position of the counterweight block 51 on the Mass axis counterweight module 50 at the other end of the stabilizing lever 41 is controlled to adjust the balance.
[0049] In some of the embodiments, the polarization axis rotation module 70 adopts a high-precision electric rotating table, which uses a high-precision motor and a high-precision AV reducer to ensure the repeated positioning accuracy of the scanning device during 360° rotation; the scanning probe 80 adopts a special corrugated scanning device imported from abroad. Of course, according to needs, it can also replace the special scanning equipment required for other working conditions.
[0050] In addition, in order to realize the automatic control of the scanning device, Figure 2As shown, the scanning device also includes a control cabinet 90 installed on the lower leg of the gantry 10, and the control cabinet 90 adopts a PLC controller. The control cabinet 90 is electrically connected to the servo motors in the X-axis walking module 20, the Y-axis walking module 30, the Mass axis counterweight module 50, the Xfin axis module 40, the Z-axis walking module 60, and the polarization axis rotation module 70, and the scanning probe 80, respectively, for automatically controlling the operation of each travel module and controlling the scanning probe 80 to perform scanning detection.
[0051] In summary, if Figure 1 and Figure 2 As shown, the large micron-level high-precision walking scanning device for detecting satellites is mainly constructed by a support frame body 11, an X-axis main beam 12 and a Y-axis main beam 13; the main power is formed by two X-axis walking modules 20 and a Y-axis walking module 30 installed on the left and right. The Mass axis counterweight module 50, the Xfin axis module 40, the gratings of each axis and the polarization axis rotation module 70 form the main precision adjustment axis, which can meet the requirements of 10 microns for repeated positioning accuracy of 8-meter horizontal scanning and 7 microns for repeated positioning accuracy of 1-meter vertical scanning, ensuring the accuracy of the scanning probe 80 in detecting products.
