Description

Technical Field

[0001] The utility model relates to the technical field of tooling mobile detection, in particular to a mobile terminal position offset detection mechanism and a mobile terminal. Background Art

[0002] Due to large temperature differences between day and night or between seasons, it will cause deformation differences due to the thermal expansion and contraction of metals, resulting in position offsets of the fixed points of the terminal during the operation of the truss manipulator at different time periods. Currently, vernier calipers or tape measures are generally used to measure this offset, and calibration is performed after measurement. Since the offset of the position of the terminal of the truss manipulator is generally small, the measurement accuracy of manual use of vernier calipers or tape measures is poor, and it is difficult to identify the offset of the position of the terminal of the truss manipulator. And when the truss manipulator is moving, manual measurement of the offset cannot be carried out in real time, and effective analysis of the data cannot be carried out in real time. When measuring manually, the truss manipulator and the equipment need to be stopped, which will affect the production efficiency. Summary of the Utility Model

[0003] Technical Problems to be Solved by the Utility Model

[0004] Aiming at the technical problems of insufficient measurement accuracy of the existing position offset detection of the terminal of the truss manipulator, difficulty in identifying the offset amount, inability to measure the offset in real time and without stopping the machine, the utility model provides a mobile terminal position offset detection mechanism, which improves the measurement accuracy of the position offset amount of the mobile terminal, and can detect the offset amount in real time and without stopping the machine, effectively analyze the data in real time and will not affect the production efficiency;

[0005] The utility model provides a mobile terminal, which can detect the offset amount in real time and without stopping the machine, effectively analyze the data in real time and will not affect the production efficiency.

[0006] Technical Solutions

[0007] To solve the above problems, the technical solutions provided by the utility model are as follows:

[0008] A mobile terminal position offset detection mechanism includes a support plate, which includes a first plate surface, a second plate surface and a third plate surface that are vertically connected. The first plate surface extends out two ends that are perpendicular to each other, and the ends are respectively vertically connected to the second plate surface and the third plate surface, and the second plate surface and the third plate surface are perpendicular to each other; the first plate surface is provided with a first sensor; the second plate surface is provided with a second sensor; the third plate surface is provided with a third sensor, and the sensing surfaces of the first sensor, the second sensor and the third sensor are of a three-axis direction structure.

[0009] Bracket Plate: As the support structure of the entire system, it is made of a material that is not easily deformed to ensure the stability and accuracy of the sensor. The bracket plate is designed in an L-shaped structure and consists of three mutually perpendicular plate surfaces, namely the first plate surface, the second plate surface, and the third plate surface. The first plate surface: The first sensor is installed on it, which is usually used to measure the displacement change along one axial direction. The second plate surface: The second sensor is installed on it, which is used to measure the displacement change along another axial direction. The third plate surface: The third sensor is installed on it, which is used to measure the displacement change along the third axial direction. The three sensors, namely the first sensor, the second sensor, and the third sensor, respectively and real-time detect the positions of the manipulator moving terminal of the truss along the X-axis, Y-axis, and Z-axis of the truss manipulator coordinate system. By comparing the data measured twice before and after, it is possible to accurately calculate whether the terminal position is offset and the offset amount. The first plate surface, the second plate surface, and the third plate surface are arranged along the X-axis, Y-axis, and Z-axis of the truss manipulator coordinate system. The first sensor, the second sensor, and the third sensor are arranged facing upwards relative to the plate surface, that is, the bottom of the sensor is connected to the plate surface. Therefore, the sensing surfaces of the first sensor, the second sensor, and the third sensor are also of a three-axis direction structure, and can adapt to the moving direction of the moving terminal manipulator for detection.

[0010] Optionally, a number of cards are provided on the bracket plate, and two of the cards are snap-connected to a single sensor.

[0011] The cards are used to fix the sensor, ensuring that the sensor can be stably installed on the bracket plate, making the installation and disassembly of the sensor simple and fast, which is beneficial for maintenance and replacement. Through the precise snap-fit between the card and the sensor, it can be ensured that the sensor can be accurately aligned with the position to be monitored during installation.

[0012] Optionally, the bracket plate is made of invar alloy material.

[0013] Invar alloy is a special alloy mainly composed of iron and nickel, with the nickel content being approximately 36%. This alloy has a very low coefficient of thermal expansion and almost exhibits zero thermal expansion characteristics within a certain temperature range. Invar alloy is therefore also known as constant steel. The coefficient of thermal expansion of invar alloy is very low and is close to zero in most temperature ranges. Even in an environment with large temperature changes, the bracket plate will not deform due to thermal expansion and contraction, thus ensuring that the accuracy of the sensor is not affected. Due to the stability of invar alloy, using it as the bracket plate can ensure that the position of the sensor remains consistent throughout the working temperature range, which is crucial for applications that require high-precision measurement. Invar alloy not only has good thermal stability but also has good mechanical strength and corrosion resistance, and can be used stably for a long time.

[0014] Optionally, the first sensor is located at the vertical corner of the first board surface, and the second sensor and the third sensor are respectively located at the ends of the second board surface and the third board surface.

[0015] The first sensor, the second sensor, and the third sensor are preferably spaced apart from each other as much as possible so that the detection ranges of each sensor do not overlap, which can better detect different moving axes of the mobile terminal.

[0016] Optionally, the edge of the support board is provided with a rounded corner structure.

[0017] The rounded corner structure can reduce the existence of sharp edges and reduce the risk of personnel injury during operation, especially during production and maintenance.

[0018] Optionally, the first sensor, the second sensor, and the third sensor are all laser displacement sensors and are connected to a controller.

[0019] Laser displacement sensors have very high measurement accuracy, which can reach the micron level or even higher. Laser displacement sensors can quickly respond to position changes and are suitable for dynamic monitoring and high-speed applications. Laser displacement sensors can perform accurate measurements at relatively long distances.

[0020] A mobile device includes the mobile device position offset detection mechanism and a mobile terminal. The mobile terminal is connected with a lifting mechanism and a translation mechanism and is connected to a truss through the lifting mechanism and the translation mechanism. The mobile device position offset detection mechanism is installed on the truss, and the mobile device position offset detection mechanism is aligned and sensed with the mobile terminal.

[0021] The mobile device position offset detection mechanism is used to detect the offset amount of the mobile terminal position, including a support board installed on the truss, three laser displacement sensors (the first sensor, the second sensor, and the third sensor), and a card for fixing the sensors. The mobile terminal is the object to be detected and can be any form of mobile device, such as a robotic arm, a mobile platform, etc.

[0022] The lifting mechanism and the translation mechanism are used to control the movement of the mobile terminal in the vertical direction and the parallel direction, so as to achieve precise positioning. The truss, as the support structure of the entire system, provides sufficient stability and rigidity to ensure the accuracy of the position offset detection mechanism.

[0023] Optionally, the moving direction of the mobile terminal is a three-axis direction structure and corresponds to the first sensor, the second sensor, and the third sensor.

[0024] It ensures that the mobile terminal position offset detection mechanism can comprehensively monitor the position changes of the mobile terminal in three-dimensional space. The mobile terminal corresponds to three sensors in the position offset detection mechanism, ensuring that the position offset in each axial direction can be monitored.

[0025] Beneficial effects

[0026] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0027] The technical solution provided by the present utility model is provided with a support plate. The support plate includes a first plate surface, a second plate surface, and a third plate surface that are perpendicularly connected. Sensors are installed on the plate surfaces, and the sensing surfaces of each sensor are of a three-axis direction structure. By installing sensors on three mutually perpendicular planes, it is possible to measure the position offset of the mobile terminal in three-dimensional space. Each sensor is responsible for monitoring the change in one axial direction. The present utility model can monitor in real time and provide feedback, which helps for immediate adjustment. It can be detected during the operation of the device without stopping the machine, and will not affect the overall production efficiency. Through independent measurements in three axial directions, the overall measurement accuracy is improved. Description of the drawings

[0034] Embodiment

[0035] Combined with the attachedFigure 1 , A mobile position offset detection mechanism, including a support plate 1, which includes a first plate surface 101, a second plate surface 102, and a third plate surface 103 that are vertically connected. The first plate surface 101 extends out two mutually perpendicular ends, and the ends are respectively vertically connected to the second plate surface 102 and the third plate surface 103, and the second plate surface 102 and the third plate surface 103 are perpendicular to each other.

[0036] The support plate 1 is made of invar alloy material. It can also be made of a composite material of glass fiber and epoxy resin, and the thermal expansion coefficient of the composite material of glass fiber and epoxy resin is close to zero.

[0037] The thickness of the support plate 1 is 3 - 15 cm. An overly thin support plate 1 will affect the structural strength and rigidity. The support plate 1 itself is used to detect high-precision position offset, and a little self-deformation will affect the detection accuracy. Therefore, a certain thickness is set to ensure the structural strength and rigidity. An overly thick one will lead to too much weight and cost problems.

[0038] The first plate surface 101 is an inverted L shape, and the ends are respectively vertically connected to the second plate surface 102 and the third plate surface 103. The second plate surface 102 and the third plate surface 103 are both perpendicular to the plane where the first plate surface 101 is located. The length directions of the second plate surface 102 and the third plate surface 103 are parallel, but the installation directions of the second sensor 3 and the third sensor 4 are perpendicular.

[0039] On the first plate surface 101, a first sensor 2 is installed. On the second plate surface 102, a second sensor 3 is installed. On the third plate surface 103, a third sensor 4 is installed. The sensing surfaces of the first sensor 2, the second sensor 3, and the third sensor 4 are of a three-axis direction structure.

[0040] Several cards 104 are provided on the support plate 1, and two cards 104 are snap-connected to a single sensor.

[0041] The first sensor 2 is located at the vertical corner of the first plate surface 101, and the second sensor 3 and the third sensor 4 are respectively located at the ends of the second plate surface 102 and the third plate surface 103.

[0042] The edge of the support plate 1 is provided with a rounded corner structure, including four corners and side edges.

[0043] The first sensor 2, the second sensor 3, and the third sensor 4 are all laser displacement sensors and are connected to a controller.

[0044] Combined with the attached Figure 2, a mobile device, comprising a mobile device position offset detection mechanism 10 and a mobile terminal 30. The mobile terminal 30 is connected to a lifting mechanism 40 and a translation mechanism 50 and is connected to a truss 20 through the lifting mechanism 40 and the translation mechanism 50. The mobile device position offset detection mechanism 10 is installed on the truss 20, and the mobile device position offset detection mechanism 10 is aligned and sensed with the mobile terminal 30.

[0045] Combined with the attached Figure 3 , the moving direction of the mobile terminal 30 is a three-axis direction structure and corresponds to the first sensor 2, the second sensor 3, and the third sensor 4.

[0046] The lifting mechanism 40 and the translation mechanism 50 are rack and pinion structures and are provided with slide rails. The pinion is connected to a servo motor for controlling lifting and moving.

[0047] The mobile terminal 30 is a three-axis manipulator with three axes, each of which can move independently, thus achieving a wider range of motion and higher flexibility. It is adapted to the three-axis detection mechanism 10.

[0048] Combined with the attached Figure 4 , the truss 20 manipulator is installed on a machine tool 70, the mobile terminal 30 is installed on the truss 20 manipulator, and the truss 20 manipulator can drive the mobile terminal 30 to move.

[0049] When the mobile terminal 30 moves to the point to be measured each time, the first sensor 2, the second sensor 3, and the third sensor 4 will simultaneously measure the distance from the mobile terminal 30 and transmit the measurement data to the control system in real time. The control system calculates the position offset of the mobile terminal 30 when it reaches the point to be measured twice before and after by analyzing the measurement data. During the entire measurement process, the machine tool 70 and the mobile terminal 30 do not need to stop and can continuously measure.

[0050] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the creative concept of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
