Description

Technical Field

[0001] This application relates to the technical field of air-bearing guide rails, and in particular to a control method, system, and measuring device for measuring air-bearing guide rails. Background Technology

[0002] Air-bearing guides achieve frictionless and vibration-free smooth movement based on the dynamic and static pressure effect of gas. They feature high motion accuracy and are clean and pollution-free. Due to their error averaging effect, high guiding accuracy can be achieved with relatively low manufacturing precision. Air-bearing guides are widely used in measuring instruments and precision machinery.

[0003] In related technologies, an air-bearing guide rail measuring device is disclosed, including an air-bearing guide rail device and a rotation measuring device disposed on the air-bearing guide rail device; the air-bearing guide rail device consists of an X-axis guide structure, an X-axis air-bearing platform, a Y-axis guide structure, a Y-axis air-bearing platform, a column, and a Z-axis guide structure; the X-axis guide structure is fixed on the upper side of the base, the X-axis air-bearing platform is disposed on the X-axis guide structure, the Y-axis guide structure is fixed on the X-axis air-bearing platform, the Y-axis air-bearing platform is disposed on the Y-axis guide structure, the column is vertically disposed on the Y-axis air-bearing platform, and the Z-axis guide structure is vertically disposed on the side of the column; the rotation measuring device includes an electrically controlled rotary table and a measuring head disposed on the electrically controlled rotary table, the bottom end of the electrically controlled rotary table is disposed on the Z-axis guide structure, the measuring head is disposed on the top end of the electrically controlled rotary table, and the electrically controlled rotary table can rotate 360° in a vertical plane.

[0004] Regarding the aforementioned related technologies, the inventors discovered the following drawbacks: When performing batch testing on objects to be tested, it is often necessary to set up multiple air-bearing guide rail measuring devices. If one person operates the device, it is necessary to wait for the current object to be measured to be completed before measuring the next object, which is inefficient. If multiple people operate the device, although the efficiency is improved, the labor cost is high. Summary of the Invention

[0005] In order to reduce labor costs and improve measurement efficiency, this application provides a control method, system and device for measuring air-bearing guide rails.

[0006] Firstly, this application provides a control method for measuring air-bearing guide rails, which adopts the following technical solution:

[0007] A control method for measuring air-bearing guide rails includes:

[0008] Obtain the position information of the object under test;

[0009] Based on a preset working mapping table, the number of the air-bearing guide rail measuring device is determined; wherein, the working mapping table includes the position of the object to be detected and the number of the air-bearing guide rail measuring device, and the position of the object to be detected and the number of the air-bearing guide rail measuring device correspond one-to-one.

[0010] Obtain measurement requirement information;

[0011] Based on the measurement requirements, the corresponding numbered air-bearing guide rail measuring device is controlled to operate in accordance with the measurement requirements.

[0012] By adopting the above technical solution, the corresponding air-bearing guide rail measuring device is determined based on the obtained position information of the object to be measured. Then, based on the obtained measurement requirement information, the corresponding numbered air-bearing guide rail measuring device is controlled to work according to the measurement requirement information. Since it is only necessary to confirm the position of each object to be measured to control the corresponding air-bearing guide rail measuring device to work, both labor costs are reduced and measurement efficiency is improved.

[0013] Optionally, the control method further includes:

[0014] When all the air-bearing guide rail measuring devices are in working condition, the working time of each air-bearing guide rail measuring device is obtained respectively.

[0015] Based on the measurement requirement information and the working time, the priority for the air-floating guide rail measuring device to complete its work is obtained;

[0016] Obtain measurement instructions;

[0017] Based on the measurement command, prompt information is output according to the priority.

[0018] When all the air-bearing guide rail measuring devices are in working condition, it means that it is currently impossible to continue measuring other objects to be measured; therefore, it is necessary to wait. In order to reduce the waiting time and improve the measurement efficiency, the working time of each air-bearing guide rail side device is obtained, and the priority of the air-bearing guide rail measuring device to complete its work is obtained according to the measurement requirement information. The device with higher priority will output a prompt message to remind the staff to wait at that measuring device.

[0019] Optionally, the priority for obtaining the completion of the air-bearing guide rail measuring device based on the measurement requirement information and the accumulated working time includes:

[0020] Based on the measurement requirements information, obtain the historical average duration;

[0021] The priority is obtained based on the difference between the historical average duration and the duration already worked.

[0022] Optionally, obtaining the measurement requirement information includes:

[0023] Acquire the image information of the object under test;

[0024] The image information is compared with the image information in the preset measurement requirement information database. If the two match, the corresponding measurement requirement information in the measurement requirement information database is retrieved. The image information and measurement requirement information in the measurement requirement information database have a many-to-one mapping relationship.

[0025] By adopting the above technical solution, image information of the object to be measured is acquired and compared with image information in the measurement requirement information database to determine whether the two match. When a match is found, the corresponding measurement requirement information is retrieved, thus eliminating the need for external input.

[0026] Optionally, the control method further includes:

[0027] Obtain the serial number information of the idle air-bearing guide rail measuring device;

[0028] Based on the number information, a reminder message is output.

[0029] By adopting the above technical solution, it is easier for staff to quickly find available air-bearing guide rail measuring devices in complex working environments.

[0030] Secondly, this application provides a control system for measuring air-bearing guide rails, which adopts the following technical solution:

[0031] A control system for measuring air-bearing guide rails, comprising:

[0032] The location information acquisition module is used to acquire the location information of the object to be measured;

[0033] The processing module determines the number of the air-bearing guide rail measuring device based on a preset working mapping table; wherein, the working mapping table includes the position of the object to be detected and the number of the air-bearing guide rail measuring device, and the position of the object to be detected and the number of the air-bearing guide rail measuring device correspond one-to-one.

[0034] The information acquisition module is used to acquire measurement requirement information;

[0035] The control module, based on the measurement requirement information, controls the corresponding numbered air-bearing guide rail measuring device to operate in accordance with the measurement requirement information.

[0036] By adopting the above technical solution, the processing module determines the corresponding air-bearing guide rail measuring device based on the position information of the object to be measured obtained by the position information acquisition module. Then, the control module controls the corresponding numbered air-bearing guide rail measuring device to work according to the measurement requirement information obtained by the information acquisition module. Since it is only necessary to confirm the position of each object to be measured to control the corresponding air-bearing guide rail measuring device to work, it reduces labor costs and improves measurement efficiency.

[0037] Thirdly, this application provides an air-bearing guide rail measuring device, which adopts the following technical solution:

[0038] An air-bearing guide rail measuring device, comprising:

[0039] Base;

[0040] The first air-bearing shaft is installed on the base;

[0048] The first air flotation sleeve slides along the X-axis, the second air flotation sleeve slides along the Y-axis, and the third air flotation shaft slides along the Z-axis.

[0049] By adopting the above technical solution, all three air intake branches can be connected to an external air pump. If the first and second air float shafts need to slide, the solenoid valves on the corresponding air intake branches are opened, so that the air pump supplies air to the first and second air float sleeves to form an air film.

[0050] Optionally, the measuring device further includes:

[0051] The first counterweight is slidably connected to the column, and the sliding direction is parallel to the sliding direction of the second air flotation sleeve; the first counterweight is connected to the end of the second air flotation sleeve away from the base.

[0052] The purpose of setting up a counterweight seat by adopting the above technical solution is to install counterweight blocks on the counterweight seat to increase the weight of the counterweight seat in order to balance the weight of the second air buoyancy shaft.

[0053] Optionally, a grating ruler is provided on the first air bearing shaft, the second air bearing shaft, and the third air bearing shaft.

[0054] By adopting the above technical solution, the purpose of setting the grating ruler is to accurately control the sliding distance of the corresponding air bearing shaft.

[0055] In summary, this application has at least the following beneficial effects:

[0056] 1. By determining the corresponding air-bearing guide rail measuring device based on the obtained position information of the object to be measured, and then controlling the corresponding numbered air-bearing guide rail measuring device to work according to the obtained measurement requirement information, it is only necessary to confirm the position of each object to be measured to control the corresponding air-bearing guide rail measuring device to work. Therefore, it reduces labor costs and improves measurement efficiency.

By acquiring the working time of each air-bearing guide rail measuring device when all air-bearing guide rail measuring devices are in operation, and obtaining the priority of the air-bearing guide rail measuring devices to complete their work based on the measurement requirements and the working time, the waiting time of the object to be measured can be reduced and the measurement efficiency can be improved.

Detailed Implementation

[0070] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the appendices in the embodiments of the present invention. Figure 1 -Appendix Figure 10 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] This application discloses an air-bearing guide rail measuring device in one embodiment. As one implementation of this device, see below. Figure 1 The device may include:

[0072] Base 110;

[0073] The first air-bearing shaft 120 is mounted on the base 110 and serves as the stator of the first linear motor.

[0074] The first air bearing sleeve 130 is slidably connected to the first air bearing shaft 120 and serves as the mover of the first linear motor.

[0075] The column 140 is fixedly connected to the first air flotation sleeve 130;

[0076] The second air-bearing shaft 150 is mounted on the column 140 and serves as the stator of the second linear motor.

[0077] The second air bearing sleeve 160 is slidably connected to the second air bearing shaft 150 and serves as the mover of the second linear motor.

[0078] The third air bearing sleeve 170 is fixedly connected to the side wall of the second air bearing sleeve 160 and serves as the stator of the third linear motor.

[0079] The third air bearing shaft 180 is slidably sleeved in the third air bearing sleeve 170 and serves as the mover of the third linear motor. Additionally, a measuring tool, such as a camera, can be mounted on one end of the third air bearing shaft 180. A second counterweight seat 181 is bolted to the other end of the third air bearing shaft 180. A counterweight is added to the second counterweight seat 181 according to the weight of the measuring tool.

[0080] There are three intake branch pipes 190, which are respectively connected to the first air flotation sleeve 130, the second air flotation sleeve 160 and the third air flotation sleeve 170. Each of the first air flotation sleeve 130, the second air flotation sleeve 160 and the third air flotation sleeve 170 has an air passage. Each of the three intake branch pipes 190 is connected to a solenoid valve 210. The free ends of the three intake branch pipes 190 can be connected to an external air supply device (such as an air pump).

[0081] The first air flotation sleeve 130 slides along the X-axis, the second air flotation sleeve 160 slides along the Y-axis, and the third air flotation shaft 180 slides along the Z-axis.

[0082] The first counterweight seat 220 is slidably connected to the column 140, and the sliding direction is parallel to the sliding direction of the second air flotation sleeve 160. The first counterweight seat 220 is connected to the end of the second air flotation sleeve 160 away from the base 110. A counterweight block can be detachably connected to the first counterweight seat 220, and the detachable connection method can be a bolt connection. For example, if a 1kg load is added to the front end of the third air flotation shaft 180, a 1kg counterweight needs to be added to the rear end of the second counterweight seat 181, and a 2kg counterweight needs to be added to the first counterweight seat 220.

[0083] The first counterweight 220 is connected to the end of the second air flotation sleeve 160 furthest from the base 110 in the following manner:

[0084] Two guide wheels 230 are bolted to one end of the column 140 away from the base 110. A steel wire rope 240 is fixedly connected to one end of the counterweight 220. The steel wire rope 240 passes around the two guide wheels 230 and is fixedly connected to the second air flotation sleeve 160.

[0085] A grating ruler (not shown in the figure) is installed on the first air bearing shaft 120, the second air bearing shaft 150 and the third air bearing shaft 180, respectively, to detect the sliding distance of the first air bearing sleeve 130, the second air bearing sleeve 160 and the third air bearing shaft 180.

[0086] Contact-type limiting members 250 are fixedly connected to both ends of the first air bearing shaft 120. The contact-type limiting members 250 are used to limit the sliding of the first air bearing sleeve 130. The contact-type limiting members 250 can be contact switches, etc.

[0087] The implementation principle of this embodiment is as follows:

[0088] When measuring the X, Y, and Z axes of the object under test, first control the first linear motor to start, and open the solenoid valve 210 corresponding to the first air float 130. After the X-axis measurement is completed, control the second linear motor to start, and open the solenoid valve 210 corresponding to the second air float 150 to perform the Y-axis measurement. Then control the third linear motor to start, and open the solenoid valve 210 corresponding to the third air float 170 to perform the Z-axis measurement.

[0089] The second embodiment of this application discloses a control method for measuring air-bearing guide rails. (Refer to...) Figure 2 As one embodiment of the control method, the control method may include S110-S140:

[0090] S110, Obtain the position information of the object to be measured;

[0091] Specifically, refer to Figure 3 Position frames are pre-marked at the corresponding air-bearing guide rail measuring devices. When the object to be measured is to be tested, it is placed in the position frame.

[0092] One approach is to input the location information of the object to be tested through an input module (such as a touch screen). For example, A, B, C, etc. can be pre-painted in the location frame. When the object to be tested is placed at location A, it means that A has been input through the input module. Alternatively, a pressure sensor can be installed in the location frame. When the pressure value obtained by a certain pressure sensor is greater than the pressure threshold, the object to be tested is assumed to be at that location.

[0093] S120, based on the preset working mapping table, determine the number of the air-bearing guide rail measuring device;

[0094] The working mapping table includes the position of the object to be detected and the number of the air-bearing guide rail measuring device, with a one-to-one correspondence between the position of the object to be detected and the number of the air-bearing guide rail measuring device.

[0095] For example, the air-bearing guide rail measuring device corresponding to position A is numbered 1, and the air-bearing guide rail measuring device corresponding to position B is numbered 2, etc.

[0096] S130, Obtain measurement requirement information;

[0097] Specifically, the measurement requirement information can be "X, Y, Z measurement" or "X, Y measurement" of the object to be measured.

[0098] S140, based on the measurement requirement information, controls the corresponding numbered air-bearing guide rail measuring device to work according to the measurement requirement information.

[0099] Specifically, controlling the air-bearing guide rail measuring device to operate according to the measurement requirements is actually achieved by controlling the opening and closing of the corresponding solenoid valves and the corresponding linear motors. For example, if the measurement requirement is "X, Y measurement", and the air-bearing guide rail measuring device is numbered 2, then controlling the solenoid valve corresponding to X in device number 2 will open the solenoid valve corresponding to Y, and start the linear motors corresponding to X and Y.

[0100] Reference Figure 4 As a specific embodiment of S130, it may include S131-S134:

[0101] S131, acquire image information of the object to be tested;

[0102] Specifically, each location frame is equipped with an image acquisition device (such as a camera) to acquire image information of the object under test.

[0103] S132, compare the image information with the image information in the preset measurement requirement information database;

[0104] S133, if the two match, retrieve the corresponding measurement requirement information from the measurement requirement information database; wherein, the image information and the measurement requirement information in the measurement requirement information database have a many-to-one mapping relationship.

[0105] Specifically, the image information in the measurement requirement database consists of images of the objects to be measured corresponding to historical measurement requirement information. Each time an object is measured, an image of the object is acquired and associated with the measurement requirement information. If a perfectly matching image exists, only one image is retained in the database. When measuring the current object, the image information of the current object is acquired beforehand and compared with the images in the measurement requirement database. If a match is found, the associated measurement requirement information can be directly retrieved, and the corresponding numbered air-bearing guide rail measuring device is controlled to perform the measurement according to that requirement information. Here, "matching" refers to identical shapes, although sizes may differ.

[0106] S134, if the two do not match, then receive the measurement requirement information from the external input, wherein the measurement requirement information is input from the external input through the input module.

[0107] Reference Figure 5As another embodiment of the control method, the control method may include S210-S240:

[0108] S210, when all air-bearing guide rail measuring devices are in operation, obtain the operating time of each air-bearing guide rail measuring device;

[0109] Specifically, timing is started when the air-bearing guide rail measuring device starts working, and the working time is associated with the corresponding air-bearing guide rail measuring device number.

[0110] S220, based on measurement requirement information and the duration of operation, obtains the priority for the air-floating guide rail measuring device to complete its work;

[0111] S230, Obtain measurement command;

[0112] Specifically, the measurement command can be an external input, such as pressing a measurement button; or it can be a sensor such as a grating installed at the edge of the measurement area to detect the human body. When a human body is detected entering the measurement area, it indicates that there is an object to be measured, and the measurement command can be automatically obtained.

[0113] S240 outputs prompt information according to priority based on measurement commands;

[0114] Specifically, for example, if task number 2 is completed first, then task number 3, and finally task number 1, then the priority is 2, 3, 1. The prompts can be displayed via audio-visual aids or on electronic screens within the factory, in which case the prompt could be "Please wait at task number 2".

[0115] Reference Figure 6 As a specific implementation of S220, S220 may include S221-S222:

[0116] S221, Based on the measurement requirement information, obtain the historical average duration;

[0117] Specifically, when measuring the object to be measured, the working time of measuring the object to be measured is associated with the measurement requirement information. Under the same measurement requirement information, the average measurement time is the historical average time corresponding to the measurement requirement information.

[0118] S222 prioritizes tasks based on the difference between the historical average duration and the duration already worked.

[0119] Specifically, based on the measurement requirement information corresponding to the current object under test, the historical average duration corresponding to the measurement requirement information is obtained. Then, the difference between the historical average duration and the current working duration is obtained. Based on the difference for each air-bearing guide rail measuring device, a priority is obtained. If a difference value is negative, the difference between the longest historical duration corresponding to the measurement requirement information corresponding to that negative difference and the current working duration is obtained.

[0120] Reference Figure 7 As another embodiment of the control method, the control method may include S310-S320:

[0121] S310, Obtain the serial number information of the idle air-bearing guide rail measuring device;

[0122] S320 outputs a reminder message based on the serial number information.

[0123] Specifically, the reminder message could be "Please take a measurement at point X," and the message could be displayed on an electronic screen within the factory area.

[0124] Additionally, if there are two or more idle air-bearing guide rail measuring devices, then before S320, refer to... Figure 8 S311-S312 also need to be executed:

[0125] S311, Obtain the current position information of the object under test;

[0126] S312, based on the current location information and the location information of the air-bearing guide rail measuring device, determine the location of the air-bearing guide rail measuring device closest to the worker.

[0127] Specifically, once staff enter the measurement area, the current location information of the object to be measured can be obtained using the positioning module on the staff's mobile terminal. The location information of the air-bearing guide rail measuring device is preset. Then, based on the distance formula between two points, the distance from the idle air-bearing guide rail measuring device to the staff is obtained. Finally, the minimum distance is determined, and the X number in the reminder message is the number of the air-bearing guide rail measuring device corresponding to the minimum distance.

[0128] The implementation principle of this embodiment is as follows:

[0129] The position information of the object to be measured is obtained, and then the number of the air-bearing guide rail measuring device is determined based on the working mapping table. Then the measurement requirement information is obtained, and based on the measurement requirement information, the corresponding number of the air-bearing guide rail measuring device is controlled to work according to the measurement requirement information.

[0130] When all air-bearing guide rail measuring devices are in operation, the working time of each air-bearing guide rail measuring device is obtained. Based on the measurement requirement information and the working time, the priority of the air-bearing guide rail measuring device to complete the work is obtained. Then, the measurement command is obtained, and based on the measurement command, prompt information is output according to the priority.

[0131] The third embodiment of this application provides a control system for measuring air-bearing guide rails. (Refer to...) Figure 9 As one embodiment of the control system, the control system may include:

[0132] The location information acquisition module 310 is used to acquire the location information of the object to be measured.

[0133] The processing module 320 determines the number of the air-bearing guide rail measuring device based on a preset working mapping table; wherein, the working mapping table includes the position of the object to be detected and the number of the air-bearing guide rail measuring device, and the position of the object to be detected and the number of the air-bearing guide rail measuring device correspond one-to-one.

[0134] Information acquisition module 330 is used to acquire measurement requirement information;

[0135] The control module 340, based on the measurement requirements, controls the corresponding numbered air-bearing guide rail measuring devices to operate according to the measurement requirements. The control module 340 is connected to the solenoid valves 210 and linear motors of all the air-bearing guide rail measuring devices.

[0136] The control system may also include:

[0137] Image information acquisition module 350 is used to acquire image information of the object to be measured;

[0138] The processing module 320 compares the image information with the image information in the preset measurement requirement information database. If the two match, the information acquisition module 330 retrieves the corresponding measurement requirement information from the measurement requirement information database. The image information and measurement requirement information in the measurement requirement information database have a many-to-one mapping relationship.

[0139] Reference Figure 10 As another embodiment of the control system, the control system may include:

[0140] The duration acquisition module 360 ​​is used to acquire the working duration of each air-bearing guide rail measuring device and the historical average duration based on the measurement requirement information when all air-bearing guide rail measuring devices are in working condition.

[0141] Priority acquisition module 370 obtains priority based on the difference between the historical average duration and the duration already worked;

[0142] The instruction acquisition module 380 is used to acquire measurement instructions;

[0143] The information output module 390 outputs prompt information according to the priority based on the measurement command.

[0144] In addition, when there is an idle air-bearing guide rail measuring device, the processing module 320 will obtain the number information of the idle air-bearing guide rail measuring device, and then the information output module 390 will output a reminder message based on the number information.

[0145] The implementation principle of this embodiment is as follows:

[0146] The position information acquisition module 310 acquires the position information of the object to be measured, and the post-processing module 320 determines the number of the air-bearing guide rail measuring device based on the working mapping table. Then, the information acquisition module 330 acquires the measurement requirement information, and the control module 340 controls the corresponding number of the air-bearing guide rail measuring device to work according to the measurement requirement information based on the measurement requirement information.

[0147] When all the air-bearing guide rail measuring devices are in operation, the duration acquisition module 360 ​​acquires the working duration of each air-bearing guide rail measuring device. The priority acquisition module 370 obtains the priority of the air-bearing guide rail measuring device to complete its work based on the measurement requirement information and the working duration. Then, the instruction acquisition module 380 acquires the measurement instruction, and the information output module 390 outputs prompt information according to the priority based on the measurement instruction.

[0148] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
