Description

Technical Field

[0001] This utility model relates to the field of sensors, specifically a microwave and laser combined sensor. Background Technology

[0002] Microwave sensors utilize the propagation characteristics of microwave signals to detect the presence, distance, speed, shape, and other properties of objects by emitting and receiving microwave signals. Microwave signals can penetrate objects and reflect back, and information about the target object is obtained by analyzing the reflected signals. Laser sensors use laser beams to detect objects, typically employing laser triangulation, LiDAR, or Time-of-Flight (ToF) technology to measure the distance between the target and the sensor. Laser sensors offer high precision, high resolution, and a long measurement range.

[0003] However, the traditional combination of microwave and laser sensors measures the object by moving it between the microwave and laser sensors. But the distance between the two sensors cannot be adjusted. For objects that are too large or too small, a fixed distance may cause the object to not be completely within the effective detection range of the two sensors. For example, a small object may only be captured by one sensor, while a large object may be beyond the detection boundary of one sensor, resulting in incomplete measurement data. Utility Model Content

[0004] The purpose of this invention is to provide a microwave and laser combined sensor to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A microwave and laser combined sensor includes a microwave sensor and a laser sensor. Fixing slots are provided on both sides of the microwave sensor and the laser sensor. Sliding blocks are provided at the lower ends of both the microwave sensor and the laser sensor. Fixing plates are fixedly connected to the upper ends of the two sliding blocks near their respective sides. The four fixing plates are respectively bolted to one side of the fixing slots of the microwave sensor and the laser sensor. Adjustment components for spacing movement are provided at the lower ends of both the microwave sensor and the laser sensor near their respective sides.

[0007] Preferably, the adjustment component includes a guide plate, the upper end of which has guide grooves on both sides, and limit plates are fixedly installed at both ends of the guide plate.

[0008] Preferably, both sliding blocks have sliding grooves inside, and the sliding grooves of both sliding blocks are slidably fitted inside the limiting plate.

[0009] Preferably, the guide plate has a first bushing fixedly sleeved on both sides near the center, and a lead screw is sleeved inside each of the two first bushings. A connecting block is rotatably connected to the outside of the two lead screws.

[0010] Preferably, one side of each of the two connecting blocks is fixedly connected to one side of each of the two sliding blocks, and the two connecting blocks are located at the lower center of one side of each of the two sliding blocks.

[0013] The beneficial effects of this utility model are:

Whether the object is too large or too small, it ensures that the object is completely within the effective detection range of the sensor, avoiding detection blind spots or errors caused by a fixed distance. Adjusting the distance according to the actual size of the object ensures more accurate detection results from both the microwave and laser sensors, reducing misjudgments or missed detections.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please operate. Figure 1 and Figure 2 As shown, a microwave and laser combined sensor includes a microwave sensor 1 and a laser sensor 2. Fixing slots 6 are provided on both sides of the microwave sensor 1 and the laser sensor 2. Sliding blocks 4 are provided at the lower ends of both the microwave sensor 1 and the laser sensor 2. Fixing plates 5 are fixedly connected to the upper ends of the two sliding blocks 4 near both sides. The four fixing plates 5 are respectively connected to one side of the fixing slots 6 of the microwave sensor 1 and the laser sensor 2 by bolts. Adjustment components 3 for spacing movement are provided at the lower ends of both the microwave sensor 1 and the laser sensor 2 near one side.

[0023] In a specific embodiment, microwave sensor 1 detects a target object by emitting microwave signals and receiving reflected signals. The microwave signal is reflected back after encountering the target. By analyzing parameters such as the intensity and time delay of the reflected signal, the sensor can determine information such as the target's distance, speed, and shape. Laser sensor 2 detects a target object by emitting a laser beam and receiving reflected light. Lasers have high directionality and concentration, thus enabling high-precision distance measurement. Microwave sensor 1 and laser sensor 2 are common models in the prior art, such as Honeywell Xenon, SICKTiM series, Pepperl+Fuchs LMT series, SICKDME series, KeyenceIL series, and OMRON Z4M series. Adjustment component 3 allows the spacing between microwave sensor 1 and laser sensor 2 to be adjusted to adapt to different detection needs. For example, adjusting the spacing can optimize the detection range of both sensors.

[0024] Please operate. Figures 1 to 4As shown, as a technical optimization of this utility model, the adjustment component 3 includes a guide plate 31. The upper end of the guide plate 31 has guide grooves 32 on both sides. Limiting plates 33 are fixedly installed at both ends of the guide plate 31. The interior of the two sliding blocks 4 has sliding grooves 35. The sliding grooves 35 of the two sliding blocks 4 are slidably sleeved inside the limiting plates 33. The interior of the guide plate 31 has first bushings 37 fixedly sleeved on both sides near the center. The interior of the two first bushings 37 has lead screws 36. The outer sides of the two lead screws 36 are rotatably connected to connecting blocks 34.

[0025] Furthermore, one side of each of the two connecting blocks 34 is fixedly connected to one side of each of the two sliding blocks 4, and the two connecting blocks 34 are located at the lower center of one side of each of the two sliding blocks 4. The outer side of each of the two lead screws 36 away from the first bushing 37 is rotatably fitted with a second bushing 38. The outer side of each of the two second bushings 38 is fixedly fitted inside one end of the limiting plate 33. One end of each of the two lead screws 36 is fixedly connected with a handle 39.

[0026] In a specific embodiment, when it is necessary to adjust the distance between the microwave sensor 1 and the laser sensor 2, the operator manually rotates the handle 39, which in turn drives the lead screw 36 to rotate. The two ends of the lead screw 36 rotate inside the first bushing 37 and the second bushing 38, respectively. Furthermore, the lead screw 36 rotates inside the connecting block 34, and the connecting block 34 can move linearly outside the lead screw 36, thereby driving the sliding block 4 to move on the upper end of the guide plate 31 and inside the guide groove 32. This achieves the desired distance between the microwave sensor 1 and the laser sensor 2, preventing objects that are too large or too small from falling within the effective detection range of the microwave sensor 1 and the laser sensor 2 due to the fixed distance.

[0027] When this invention is in use, if it is necessary to adjust the distance between the microwave sensor 1 and the laser sensor 2, the operator manually rotates the handle 39, which in turn drives the lead screw 36 to rotate. The two ends of the lead screw 36 rotate inside the first bushing 37 and the second bushing 38, respectively. Furthermore, the lead screw 36 rotates inside the connecting block 34, and the connecting block 34 can move linearly outside the lead screw 36, thereby driving the sliding block 4 to move on the upper end of the guide plate 31 and inside the guide groove 32. This achieves the desired distance between the microwave sensor 1 and the laser sensor 2, preventing objects that are too large or too small from falling outside the effective detection range of the microwave sensor 1 and the laser sensor 2 due to a fixed distance.
