Abstract
Description
Technical Field
[0001] This application relates to the field of AGV (Automated Guided Vehicle) technology, specifically to a laser probe protection mechanism for a laser-guided forklift-type AGV. Background Technology
[0002] Laser-guided forklift AGVs are widely used in the industrial logistics field. Their laser probes need to continuously emit / receive beams to achieve accurate positioning. In the use of AGVs, in order to avoid damage to the laser probes from the external environment, laser probe protection mechanisms are often used to provide external protection for the laser probes.
[0003] A search revealed that patent CN217867982U discloses a laser probe protection mechanism for a laser-guided forklift AGV. This mechanism uses a circular protective cover to protect the laser sensor from collision damage. The circular protective cover also increases the detection range of the laser sensor, thereby improving detection efficiency.
[0004] While the existing technology can provide external protection for the laser head-up of AGV vehicles, when such devices are used in dusty, humid, or oily working environments, contaminants (such as dust, water mist, and fibers) easily adhere to the surface of the probe protective cover, causing laser scattering or refraction, which seriously reduces navigation accuracy. In addition, the overall integrated design results in high maintenance costs. Utility Model Content

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0031] Reference Figures 1 to 5This application provides a laser probe protection mechanism for a laser-guided forklift AGV, including a separate fixed base 1 and a protective cover 2 for providing external protection to the laser probe. The fixed base 1 includes a fixedly connected base plate 101 and a damping pad 103. A through slot 110 for the laser probe to pass through is opened at the center of the fixed base 1. The protective cover 2 includes a fixedly connected spherical cover 201 and a connecting sleeve 202. A connecting groove 111 that engages with the bottom of the connecting sleeve 202 is opened at the top center of the fixed base 1. An air curtain mechanism 4 for providing self-cleaning protection to the protective cover 2 is provided on the outside of the fixed base 1. The air curtain mechanism 4 includes multiple sets of guide seats 401 arranged in a ring on the upper surface of the base plate 101 and bolts. The air pump 410 connected to one side of the base plate 101 guides the protective cover 2 to the fixed base 1 through the engagement of the connecting sleeve 202 and the connecting groove 111. The device can be guided and placed at the laser probe position of the AGV trolley through the through groove 110 in the center of the fixed base 1. When the device is in use, the air curtain mechanism 4 on the outside of the fixed base 1, i.e., the cooperation of multiple sets of guide seats 401 and air pump 410, can form an annular air barrier outside the spherical cover 201 to continuously block dust and water mist from adhering. The modular and separate design of the fixed base 1, protective cover 2 and air pump 410 makes it convenient for staff to disassemble and replace individual parts, reducing maintenance costs.
[0032] Reference Figure 1 , Figure 2 and Figure 4 In one aspect of this embodiment, the air curtain mechanism 4 further includes an air inlet pipe 402 and an air inlet interface 403 that are connected through the air inlet pipe 402 inside the seat plate 101, and the air inlet interface 403 is located on the side of the seat plate 101 that is connected to the air pump 410.
[0033] The air intake pipe 402 is connected to multiple sets of guide seats 401. An adsorption filter 411 is fixedly installed at the air inlet of the air pump 410. The guide seat 401 has a flow channel that communicates with the air intake pipe 402. A stainless steel jet nozzle is installed at the air outlet of the flow channel. When the device is in use, the air pump 410 is turned on, which drives the air to pass through the adsorption filter 411 and send it to the air intake interface 403. Then, the air is sent into the air intake pipe 402 through the air intake interface 403 and finally sprayed out by multiple sets of guide seats 401.
[0034] Reference Figures 3 to 5In one aspect of this embodiment, multiple sets of damping springs 203 are fixedly installed on the bottom surface of the connecting sleeve 202, and multiple sets of guide posts 112 are fixedly installed on the bottom surface of the connecting groove 111. The multiple sets of guide posts 112 are respectively sleeved and connected to the multiple sets of damping springs 203. When this device is used, by embedding the bottom of the connecting sleeve 202 into the connecting groove 111, and cooperating with the sleeved connection of the damping springs 203 and the guide posts 112, the fixed seat 1 and the protective cover 2 can be guided and combined, and the use of the damping springs 203 to protect the protective cover 2 can achieve elastic buffering.
[0035] Reference Figure 3 and Figure 5 In one aspect of this embodiment, the seat plate 101 has multiple sets of mounting hole slots 102 symmetrically formed inside, and the connecting slot 111 is provided with a limiting mechanism 3 for providing anti-detachment limiting for the connecting sleeve 202.
[0036] The limiting mechanism 3 includes a sealing ring block 310 for sealing the gap at the top of the connecting groove 111 and a threaded ring block 301 fixedly installed on the top of the fixed seat 1. The sealing ring block 310 and the threaded ring block 301 are threadedly connected. When this device is in use, the fixed seat 1 can be installed on the AGV trolley by connecting the bolt to the mounting hole groove 102. By tightening the sealing ring block 310 on the threaded ring block 301, the protective cover 2, which is guided and placed on the fixed seat 1, can be limited. The protective cover 2 on the fixed seat 1 can also be easily removed by unscrewing the sealing ring block 310 in the opposite direction and by lifting the protective cover 2 outward.
[0037] All electrical devices in this plan are powered by an external power source.
[0038] Working principle: When using the laser probe protection mechanism of this laser-guided forklift AGV, the protective cover 2 should first be guided and assembled onto the fixed base 1 by engaging the connecting sleeve 202 with the connecting groove 111. By tightening the sealing ring block 310 on the threaded ring block 301, the protective cover 2, which is guided and placed on the fixed base 1, can be limited. The air pump 410 is then positioned and installed on the fixed base 1 by bolts to complete the pre-assembly before use. When the device is in use, the fixed base 1 is guided and installed onto the outside of the laser probe by fitting the through groove 110 in the center of the fixed base 1 with the laser probe, and by connecting the bolts with the mounting hole groove 102. The fixed base 1 is then guided and installed onto the outside of the laser probe of the AGV. By opening the air pump 410 in the air curtain mechanism 4, an annular air barrier can be formed outside the spherical cover 201 to continuously block the adhesion of dust and water mist, thereby providing stable self-cleaning protection for the protective cover 2.
