Description

Technical Field

[0001] This utility model relates to the field of motorized truck technology, specifically to a dust removal device for an AGV vehicle laser scanner. Background Technology

[0002] Automated Guided Vehicles (AGVs), also known as automated guided vehicles or automated guided transport vehicles, are industrial vehicles that load goods automatically or manually, travel automatically along a set route or tow a cargo trolley to a designated location, and then load and unload goods automatically or manually.

[0003] With the improvement of automation level in my country's manufacturing enterprises, AGVs are being used more and more widely. Because of their self-navigation and obstacle avoidance capabilities, AGVs have greatly reduced the workload of operators in the logistics field. However, due to the characteristics of the laser scanner in the AGV navigation system, it is difficult for them to operate in harsh conditions such as outdoor and dusty environments. Therefore, improving the adaptability of the scanner system has become the key to expanding the application of AGVs and developing intelligent logistics.

[0004] In existing technologies, dust removal for AGVs is usually done by manual wiping or by blowing air with a fan. However, wiping can scratch the laser scanner screen and affect the subsequent use of the AGV. On the other hand, using a fan for dust removal is bulky and affects the working efficiency of the AGV.

[0005] Chinese Patent No. CN21818103U discloses a dust removal system for a laser scanner in an automotive welding production line, comprising: a compressed air system; a laser scanner; a branch air assembly with its inlet end connected to the compressed air system; and at least one air outlet connected to the outlet end of the branch air assembly. The air outlet is fixed to the laser scanner and is used to blow away dust from the laser emission area of ​​the laser scanner. This system utilizes a branch air system already present in the automotive welding production line workshop, which branches into two more lines before passing through the air outlet to blow compressed air onto the dust in the laser emission area of ​​the laser scanner.

[0006] The dust removal system disclosed above blows air onto the laser scanner through an air duct. However, during the blowing process, since the air volume is controlled by the compressed air system, when the air delivery speed of the compressed air system remains constant, the wind force on the surface of the laser scanner is at a constant value, making it difficult to effectively remove dust from the surface of the laser scanner and affecting the usability of the laser scanner surface. Utility Model Content

[0007] The present invention aims to overcome the defects in the prior art and provide a dust removal device for AGV vehicles with a simple structure, high dust removal efficiency, and the ability to achieve a sweeping effect.

[0008] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a dust removal device for an AGV vehicle laser scanner, comprising a dust removal housing and a guide hood installed inside the dust removal housing, wherein an air source connected to the guide hood is installed on the top of the dust removal housing; characterized in that a rotating main body and a diverting main body are installed inside the guide hood on the air blowing duct of the air source, the rotating main body forming an impeller that is rotated by the air source; an air inlet is formed on the top of the diverting main body, and a wind baffle assembly for controlling the air intake at the air inlet is installed on the diverting main body; a connecting pin is provided on the wind baffle assembly and swings synchronously with the rotation of the rotating main body, and a guide groove is formed on the rotating main body that is engaged with the connecting pin; an air outlet connected to the air inlet is formed at the bottom of the diverting main body.

[0009] As a preferred embodiment of the present invention, the rotating body includes a rotating shaft and an impeller located in the middle of the rotating shaft. The impeller is arranged in the radial direction of the rotating shaft and rotates synchronously with the rotating shaft.

[0010] In a preferred embodiment of this utility model, the rotating shaft is passively rotatably connected to the diversion body, and the guide groove is formed on the rotating shaft.

[0011] As a preferred embodiment of this utility model, the guide groove is connected end to end along the radial direction of the rotating shaft, and the guide groove is axially offset along the axial direction of the rotating shaft during rotation.

[0012] As a preferred embodiment of this utility model, the guide groove is an annular structure or a corrugated structure formed on the rotating shaft.

[0013] As a preferred embodiment of this utility model, the air inlet is divided into a forward air inlet and a main air inlet spaced apart. The wind deflector assembly consists of two relatively rotating wind deflector plates. A support pin for supporting the swing of the wind deflector plates is installed on the air guide shroud. The main air inlet is located on the swing path of the wind deflector plates. Corresponding connecting pins are installed on both relatively rotating wind deflector plates.

[0014] As a preferred embodiment of this utility model, the air outlet is divided into a front air outlet and a main air outlet that are spaced apart. The front air outlet is connected to the inlet air outlet, and the main air outlet is connected to the main inlet air outlet.

[0015] As a preferred embodiment of this utility model, the main air inlet is larger than the windshield size of the windshield assembly, and an air inlet notch corresponding to the front air inlet is formed at the corner of the windshield.

[0016] As a preferred embodiment of this utility model, the diversion body is provided with a plurality of air control plates located at the main air outlet.

[0017] As a preferred embodiment of this utility model, the surface of the diversion body is formed with a plurality of positioning protrusions that engage with the air control plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: by setting a wind baffle component at the air inlet to adjust the air intake, the air intake of the air inlet changes with the swing of the wind baffle component, thereby causing the air output of the diversion body to change intermittently, generating a dispersing force of vibration waves on the dust removal area, and improving the dust removal effect.

[0019] At the same time, the swinging action of the wind deflector component drives the swinging action of the actuating component, thereby driving the swinging action of the air control plate to achieve the sweeping effect of the diversion body and improve the dust removal effect.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1-6 As shown, an AGV vehicle laser scanner dust removal device includes a dust removal housing 1 and a guide hood 2 installed inside the dust removal housing 1. An air source 9 connected to the guide hood 2 is installed on the top of the dust removal housing 1. A rotating body 3 and a diverting body 4 are installed inside the guide hood 2, located on the air duct of the air source 9. The rotating body 3 has an impeller 31 that is rotated by the air source 9. An air inlet is formed on the top of the diverting body 4, and a wind baffle assembly 5 for controlling the air volume at the air inlet is installed on the diverting body 4. A connecting pin 51 is provided on the wind baffle assembly 5, which swings synchronously with the rotation of the rotating body 3. A guide groove 33 is formed on the rotating body 3 that is engaged with the connecting pin 51. An air outlet connected to the air inlet is formed at the bottom of the diverting body 4.

[0029] The air source 9 includes a first fan and a second fan distributed vertically. Both the first fan and the second fan are booster fans. The air source 9 can also provide air power to other power components.

[0030] Under the blowing action of the air source 9, the air blown out by the air source 9 passes through the rotating body 3 and the diversion body 4 in sequence. Under the action of the air source 9, the impeller 31 is driven to rotate, thereby driving the rotating body 3 to rotate synchronously.

[0031] The wind deflector 5 swings at the air inlet of the diversion body 4. During the rotation of the rotating body 3, the wind deflector 5 swings synchronously, thereby achieving phased control of the air intake at the air inlet and generating variable air volume at the air outlet.

[0032] The rotating body 3 includes a rotating shaft 32 and an impeller 31 located in the middle of the rotating shaft 32. The impeller 31 is arranged in the radial direction of the rotating shaft 32 and rotates synchronously with the rotating shaft 32. The two ends of the rotating shaft 32 are inserted into the flow guide shroud 2. The insertion of the two ends of the rotating shaft 32 realizes the overhead setting of the rotating shaft 32, so that the rotating body 3 is located between the air source 9 and the diversion body 4.

[0033] The rotating shaft 32 is passively rotatably connected to the diversion body 4. The guide groove 33 is formed on the rotating shaft 32. The guide groove 33 is connected end to end along the radial direction of the rotating shaft 32. During the rotation of the rotating shaft 32, the guide groove 33 forms an axial offset along the axial direction of the rotating shaft 32.

[0034] During the rotation of the rotating shaft 32, the connecting pin 51 slides along the length of the guide groove 33. As the guide groove 33 shifts axially along the axial direction of the rotating shaft 32 during the rotation of the rotating shaft 32, the connecting pin 51 moves along the axial direction of the rotating shaft 32. During the movement of the connecting pin 51 along the axial direction of the rotating shaft 32, the windbreak assembly 5 swings.

[0035] The guide groove 33 is an annular or corrugated structure formed on the rotating shaft 32. The specific structure of the guide groove 33 can be set according to actual needs.

[0036] The air inlet is divided into a forward air inlet 7 and a main air inlet 6 spaced apart. The wind deflector assembly 5 consists of two wind deflector plates 51 that rotate relative to each other. The guide shroud 2 is equipped with a support pin 53 for supporting the swing of the wind deflector plate 51. The main air inlet 6 is located on the swing path of the wind deflector plate 51. Corresponding connecting pins 51 are installed on both wind deflector plates 51 that rotate relative to each other.

[0037] Both the front air inlet 7 and the main air inlet 6 are set to correspond to the air source 9. The baffle plate 51 swings around the support pin 53. During the swing of the baffle plate 51, it blocks part of the front air inlet 7 and the main air inlet 6, thereby changing the air intake of the front air inlet 7 and the main air inlet 6 during the swing of the baffle plate 51.

[0038] When the impeller 31 rotates under the wind force of the wind source 9, assuming that the wind deflector 51 is in a closed state, the wind force is affected by the main baffles of the two wind deflectors 51. At this time, the air volume enters from the main air inlets 6 on both sides of the two wind deflectors 51 to avoid a large air volume in the middle. Under the rotation of the impeller 31, the connecting pin 52 is driven to slide in the guide groove 33, thereby swinging the wind deflector 51 outward to open the wind deflector 51. At this time, the air volume enters from the main air inlet 6 between the two wind deflectors 51.

[0039] The air outlet is divided into a front air outlet 71 and a main air outlet 61 that are spaced apart. The front air outlet 71 is connected to the front air inlet 7, and the main air outlet 61 is connected to the main air inlet 6.

[0040] Under the action of the swinging wind deflector 5, the wind force will change intermittently in size. The front air outlet 71 is set in front of the diversion body 4, and the main air outlet 61 is set in front of the diversion body 4. The front air outlet 71 causes the space in front of the sensor to generate the dispersing force of the vibration wave, driving the dust in the air away.

[0041] The main air inlet 6 is larger than the wind deflector of the wind deflector assembly 5, and the wind deflector 51 has an air inlet notch 54 at the corner corresponding to the front air inlet 7.

[0042] The main body 4 of the diversion body is provided with a number of air control plates 42 located at the main air outlet 61. The air control plates 42 are equipped with air control shafts 43 that are rotatably connected to the main body 4 of the diversion body. The main body 4 of the diversion body is also provided with a toggle member 8 for adjusting the rotation angle of the air control plates 42. The wind baffle assembly 5 swings and drives the toggle member 8 to swing. The toggle member 8 has a socket groove 81 for simultaneously controlling the swing of a number of air control plates 42.

[0043] The air control plate 42 can swing at the bottom of the diversion body 4 as the air control shaft 43 rotates, and the air control plate 42 is located at the main air outlet 61 to guide the air force discharged from the main air outlet 61. Under the action of the swinging air control plate 42, the sweeping effect at the main air outlet 61 is achieved.

[0044] The swing member 8 has a rotating part in the middle that is connected to the diversion body 4. The top of the swing member 8 is always in contact with the wind baffle assembly 5. Under the swing action of the wind baffle assembly 5, the bottom of the swing member 8 is driven to swing. The sleeve groove 81 is used to fit onto the air control plate 42. Under the swing action of the swing member 8, the air control plate 42 is swinged.

[0045] The surface of the diversion body 4 has a number of positioning protrusions 41 that engage with the air control plate 42. The positioning protrusions 41 pass through the diversion body 4 and are used to support the initial position of the air control plate 42.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
