Description

Technical Field

[0001] This utility model relates to the field of air-floating guide rail technology, specifically a mobile air-floating guide rail temperature detection and early warning device. Background Technology

[0002] Mobile air-bearing guide rails are core basic components in the field of modern high-end equipment manufacturing. They are widely used in equipment with extremely high requirements for motion accuracy and stability, such as lithography machines, precision measuring instruments, and ultra-precision machining tools.

[0003] According to CN117585394A, a temperature warning device for an air-bearing guide rail is disclosed. This technology discloses a technical solution including "a guide rail and an air-bearing block that can move on the guide rail, with an air-bearing surface formed between the air-bearing block and the guide rail. The temperature warning device includes a photosensitive sensor disposed on the air-bearing block, a laser emitter and a laser receiver disposed at both ends of the air-bearing block, with the laser emitter tilted upwards." It has the technical effect that "when a heat source is generated around the air-bearing guide rail and has a significant impact on the working temperature of the air-bearing surface of the air-bearing guide rail, the laser will be received by the photosensitive sensor, triggering an alarm or emergency stop, thereby protecting the equipment."

[0004] The sensor in the above solution lacks an effective self-centering clamping mechanism, which makes the sensor prone to radial deflection due to installation stress, causing the measurement spot to deviate from the preset detection area; in addition, it cannot flexibly adjust the look-ahead distance of the detection area according to the working conditions, resulting in a mismatch between the warning response time and the movement speed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mobile air-bearing guide rail temperature detection and early warning device. By adjusting the sensor angle to set the early warning detection distance, and then tightening the installation to ensure centering and reduce vibration, it achieves non-contact accurate monitoring and early warning of guide rail temperature.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile air-floating guide rail temperature detection and early warning device, comprising a guide rail and an air-floating block, wherein the air-floating block is equipped with a detection mechanism for detecting the temperature of the guide rail, the detection mechanism comprising:

[0007] An adjustment component is mounted on the air flotation block and is used to adjust the detection position;

[0008] The mounting assembly includes a cylindrical shell mounted on the adjusting assembly. A rubber head is inserted and installed at the rear end of the cylindrical shell. A clamping sleeve is inserted and installed at the front end of the rubber head, and the clamping sleeve is fitted outside the front end of the rubber head. A sleeve is threaded on the outer wall of the front end of the cylindrical shell.

[0009] An infrared temperature sensor is installed inside the bearing housing and is used to detect the temperature of the position that the guide rail is about to pass through.

[0010] Preferably, the adjusting component includes a bearing fixed to the outer wall of the air flotation block, an arc-shaped slot is provided inside the bearing, a shaft bracket is provided inside the bearing, a ring is fixed to the outer end of the shaft bracket, and the cylinder shell is fixed inside the ring. An insertion hole is provided inside the shaft bracket, and a bolt is installed through the arc-shaped slot and the insertion hole, and a nut is threaded on the bolt.

[0011] Preferably, the mounting assembly further includes a plurality of slots arranged circumferentially on the rubber head.

[0012] Preferably, the mounting assembly further includes several grooves arranged circumferentially on the inner wall of the cylinder, and several circumferentially arranged protrusions fixed to the rear end of the outer wall of the rubber head and cooperating with the grooves.

[0013] Preferably, the outer wall of the front end of the rubber head is tapered, and the inner wall of the rear end of the clamping sleeve is tapered.

[0014] Preferably, the infrared temperature sensor is a non-contact infrared temperature sensor, which integrates a wireless transmission module for wirelessly transmitting temperature data to an external receiving device.

[0015] Beneficial effects

[0016] This utility model provides a mobile air-floating guide rail temperature detection and early warning device. Compared with the prior art, it has the following advantages:

[0017] 1. After the infrared temperature sensor is installed inside the shaft seat, tightening the sleeve pushes the clamping sleeve to move axially along the conical surface, forcing the elastic rubber head to undergo radial contraction deformation, thereby uniformly clamping and fixing the infrared temperature sensor; this achieves centering and clamping of the infrared temperature sensor, avoiding installation misalignment and ensuring the accuracy of the measurement optical path; furthermore, the flexible characteristics of the elastic rubber head and its groove absorb the minute vibrations generated when the air float moves, greatly improving the measurement stability and accuracy of the infrared temperature sensor in dynamic working environments.

[0018] 2. By loosening the nuts on the bolts, the constraint on the shaft bracket is released. At this time, the operator can manually adjust the shaft bracket, causing it to rotate along the trajectory of the pre-set arc-shaped slot inside the shaft seat, along the ring sleeve and the overall structure of the cylinder shell fixed inside it. The rotation changes the detection angle of the infrared temperature sensor installed at the front end of the cylinder shell. After adjusting to the required look-ahead angle, simply tighten the nuts to securely lock the shaft bracket to the shaft seat through the clamping force generated by the bolts. By fixing the installation position of the sensor, the change in the angle between its detection direction and the horizontal plane will directly cause the landing point of its light spot on the guide rail to be advanced or delayed, thereby realizing the adjustment of the look-ahead detection distance. The detection point can be precisely set at the required position according to the actual running speed of the air flotation block and the required warning response time of the system.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a mobile air-floating guide rail temperature detection and early warning device, including a guide rail 1 and an air-floating block 3. A detection mechanism 2 is provided on the air-floating block 3 for detecting the temperature of the guide rail 1. The detection mechanism 2 includes:

[0027] Adjustment component 21 is mounted on air flotation block 3 and used to adjust the detection position;

[0028] The mounting component 22 includes a cylindrical shell 221 disposed on the adjusting component 21. A rubber head 222 is inserted and installed at the rear end of the cylindrical shell 221. A clamping sleeve 223 is inserted and installed at the front end of the rubber head 222, and the clamping sleeve 223 is sleeved on the outside of the front end of the rubber head 222. A sleeve 224 is threaded and installed on the outer wall of the front end of the cylindrical shell 221.

[0029] Infrared temperature sensor 23 is installed inside bearing seat 211 and is used to detect the temperature of the position that the guide rail 1 is about to pass through.

[0030] In this embodiment, after the infrared temperature sensor 23 is installed inside the bearing seat 211, tightening the sleeve 224 pushes the clamping sleeve 223 to move axially along the conical surface, forcing the front end of the elastic rubber head 222 to undergo radial contraction deformation, thereby uniformly clamping and fixing the infrared temperature sensor 23; this achieves centering and clamping of the infrared temperature sensor 23, avoiding installation misalignment and ensuring the accuracy of the measurement optical path; furthermore, the flexible characteristics of the elastic rubber head 222 and its groove 225 absorb the minute vibrations generated when the air float 3 moves, greatly improving the measurement stability and accuracy of the infrared temperature sensor 23 in dynamic working environments.

[0031] Specifically, the adjusting component 21 includes a bearing 211 fixed to the outer wall of the air flotation block 3. The bearing 211 has an arc-shaped slot 212 inside. The bearing 211 has a shaft bracket 213 inside. The outer end of the shaft bracket 213 is fixed with a ring 214, and the cylinder shell 221 is fixed inside the ring 214. The shaft bracket 213 has an insertion hole 215 inside. A bolt 216 is installed through the arc-shaped slot 212 and the insertion hole 215. A nut 217 is threaded on the bolt 216.

[0032] In this embodiment, by loosening the nut 217 on the bolt 216, the constraint on the shaft bracket 213 is released. At this time, the operator can manually adjust the shaft bracket 213, causing it to drive the ring sleeve 214 and the overall structure of the cylinder shell 221 fixed therein to rotate along the trajectory of the arc-shaped slot 212 inside the shaft seat 211. The rotation changes the detection angle of the infrared temperature sensor 23 installed at the front end of the cylinder shell 221. After adjusting to the required forward angle, simply tighten the nut 217, and the clamping force generated by the bolt 216 will firmly lock the shaft bracket 213 onto the shaft seat 211. By fixing the installation position of the sensor 23, the change in the angle between its detection direction and the horizontal plane will directly cause the landing point of its light spot on the guide rail 1 to be advanced or delayed, thereby realizing the adjustment of the forward detection distance. The detection point can be precisely set at the required position according to the actual running speed of the air flotation block 3 and the warning response time required by the system.

[0033] Specifically, the mounting component 22 also includes several slots 225 arranged circumferentially on the glue head 222.

[0034] In this embodiment, when the rubber head 222 is squeezed, the evenly distributed grooves 225 make it easier for the front end of the rubber head 222 to generate uniform radial elastic deformation, thereby ensuring that the infrared temperature sensor 23 is clamped in a concentric envelope manner.

[0035] Specifically, the mounting component 22 also includes several grooves 226 arranged circumferentially on the inner wall of the cylindrical shell 221, and several circumferentially arranged protrusions 227 fixed to the rear end of the outer wall of the rubber head 222 and cooperating with the grooves 226.

[0036] In this embodiment, the interlocking structure of the protrusion 227 and the groove 226 completely restricts the circumferential rotational freedom of the rubber head 222 within the cylindrical shell 221, ensuring that even under vibration conditions, the rubber head 222 and the infrared temperature sensor 23 held therein will not undergo radial deflection.

[0037] Specifically, the outer wall of the front end of the rubber head 222 is tapered, and the inner wall of the rear end of the clamping sleeve 223 is tapered.

[0038] In this embodiment, the self-centering characteristic of the conical structure is utilized to ensure that the radial contraction force generated during the clamping process is evenly distributed, thereby realizing the automatic centering and fixing of the infrared temperature sensor 23.

[0039] Specifically, the infrared temperature sensor 23 is a non-contact infrared temperature sensor, which integrates a wireless transmission module to wirelessly transmit temperature data to an external receiving device.

[0040] In this embodiment, the infrared temperature sensor 23 measures the temperature by receiving the infrared energy radiated from the surface of the guide rail 1, completely avoiding physical contact with the guide rail 1; the measured temperature data is transmitted to an external receiving device in the form of a wireless signal through the built-in wireless transmission module, and then the receiving device transmits the data to the control system for processing and analysis.

[0041] The working principle and usage process of this utility model are as follows: First, the operator needs to loosen the nut 217 on the bolt 216 in the adjustment component 21 to release the constraint on the shaft bracket 213; then, manually adjust the shaft bracket 213 so that it drives the ring sleeve 214 and the cylinder shell 221 fixed inside it to rotate along the trajectory of the arc-shaped slot 212 inside the shaft seat 211, thereby changing the detection angle of the infrared temperature sensor 23 installed at the front end of the cylinder shell 221; by observing the change in the landing point of the sensor spot on the guide rail 1, according to the actual running speed of the air float 3 and the system warning response time requirements, after accurately setting the detection point at the required forward position, tighten the nut 217 to firmly lock the shaft bracket 213 on the shaft seat 211 through the clamping force generated by the bolt 216, thus completing the angle adjustment.

[0042] Then, the infrared temperature sensor 23 is installed inside the bearing seat 211 of the mounting assembly 22. The sleeve 224 is tightened to push the clamping sleeve 223 to move axially along the conical surface, forcing the front end of the elastic rubber head 222 to undergo radial contraction deformation, thereby uniformly clamping and fixing the sensor, achieving centering and clamping of the infrared temperature sensor 23, and ensuring the accuracy of the measurement optical path; at the same time, the flexible characteristics of the elastic rubber head 222 and its groove 225 are used to absorb the vibration generated when the air float 3 moves.

[0043] Finally, the system is started. During the movement of the air-float block 3, the infrared temperature sensor 23 is driven to detect the temperature of the position that the guide rail 1 is about to pass through in real time in a non-contact manner, and the data is sent to the external receiving device wirelessly to realize continuous temperature monitoring and early warning of the entire guide rail surface.
