Description

Technical Field

[0001] This utility model relates to the field of AGV transport vehicle technology, and in particular to an AGV transport vehicle that can clean the ground. Background Technology

[0002] Currently, in the pre-production stages of lithium iron phosphate batteries, large rolls of copper / aluminum foil involve loading, unloading, and transfer processes during coating, rolling, slitting, and stacking. These processes are primarily handled manually or using AGVs (Automated Guided Vehicles). In cleanrooms, where there are fewer workers and the area is relatively large, AGVs are needed to continuously move large rolls with exposed positive and negative electrode materials. During repeated loading, unloading, and transfers, material debris easily falls from these rolls. If not cleaned regularly, this debris can pollute the cleanroom environment. Furthermore, the AGVs run over this debris, leaving tracks on the cleanroom floor and releasing dust into the air, thus polluting the air. To address this, manual cleaning with floor scrubbers is currently the primary method, while some factories use mops and rags. This is not only time-consuming and labor-intensive but also significantly impacts the temperature, humidity, and cleanliness of the cleanroom. Utility Model Content

[0003] Based on this, in response to the technical problem that current AGV transport vehicles easily shed material debris when transporting large rolls of material with exposed positive and negative electrode materials on the surface, which can pollute the cleanroom environment if not cleaned for a long time, this utility model needs to provide an AGV transport vehicle that can clean the floor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model first provides an AGV transport vehicle capable of cleaning the ground, which includes a transport vehicle body and further includes:

[0006] The cleaning roller brush is rotatably mounted on the bottom of the transport vehicle body with its axis perpendicular to the direction of travel of the transport vehicle body.

[0007] A drive unit, which is mounted on the transport vehicle body and is used to drive the cleaning roller brush to rotate;

[0008] A liquid storage tank is mounted on the transport vehicle body and is higher than the cleaning roller brush. It is connected to an infusion tube. The end of the infusion tube away from the liquid storage tank is located above the cleaning roller brush.

[0009] A waste liquid tank, mounted on the transport vehicle body and connected to a suction pipe; the end of the suction pipe away from the waste liquid tank is located on the side of the cleaning roller brush; and

[0010] The vacuum motor has its air inlet connected to the waste liquid tank.

[0011] As a further improvement of the above-mentioned solution of this utility model, two opposing brackets are installed at the bottom of the transport vehicle body, and a drive shaft is provided between the two brackets, with both ends of the drive shaft rotatably connected to the two brackets respectively. The cleaning roller brush is fixedly installed on the drive shaft.

[0012] As a further improvement of the above-mentioned solution of this utility model, the drive unit includes a drive motor, two sprockets and a transmission chain. The two sprockets are respectively fixedly installed on the output shaft of the drive motor and the drive shaft, and the transmission chain is fitted on two synchronous pulleys.

[0013] As a further improvement to the above-mentioned solution of this utility model, a cover plate is also installed at the bottom of the transport vehicle body. The cover plate is arranged along the axial direction of the cleaning roller brush and covers the cleaning roller brush. This prevents the cleaning liquid from splashing out when the cleaning roller brush is cleaning the floor.

[0014] As a further improvement to the above-mentioned solution of this utility model, the end of the infusion tube away from the storage tank is fixed to the inside of the cover plate and arranged along the axial direction of the cleaning roller brush. Multiple through holes are spaced apart on the side of the infusion tube facing the cleaning roller brush. This ensures the uniform distribution of the cleaning solution on the cleaning roller brush.

[0015] As a further improvement to the above-mentioned solution of this utility model, a lower scraper that can contact the ground is installed at the bottom of the transport vehicle body near the bottom of the cleaning roller brush. The lower scraper is arranged along the axial direction of the cleaning roller brush. The lower scraper can scrape up the residual dirt on the ground so that the dirt can be sucked away by the suction pipe.

[0016] As a further improvement to the above-mentioned solution of this utility model, an upper scraper that can contact the cleaning roller brush is fixed on the side of the cover plate near the lower scraper. The upper scraper is arranged along the axial direction of the cleaning roller brush, and the infusion tube is located on the side of the upper scraper away from the lower scraper. The upper scraper can scrape off the residual dirt on the cleaning roller brush so that the dirt can be sucked away by the suction tube.

[0017] As a further improvement of the above-mentioned solution of this utility model, a vertically arranged partition is installed inside the sewage tank, which divides the sewage tank into a sedimentation area and a sewage area. One end of the suction pipe extends into the sedimentation area, and an overflow port is provided on the partition.

[0018] As a further improvement to the above-mentioned solution of this utility model, the AGV transport vehicle that can clean the ground also includes a sewage pipe. The sewage pipe is installed on the transport vehicle body, one end of the sewage pipe is connected to the sewage area, and the other end is detachably connected to a plug.

[0019] As a further improvement to the above-mentioned solution of this utility model, the suction pipe is arranged along the axial direction of the cleaning roller brush, and multiple suction ports are spaced apart on the side of the suction pipe facing the cleaning roller brush. This ensures that as much waste liquid as possible can be collected.

[0025] To facilitate understanding of this invention, a more comprehensive description of the invention will be provided below with reference to specific embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] To address the technical problem of AGV (Automated Guided Vehicle) transport vehicles (AGVs) easily shedding material debris when handling large rolls of material with exposed positive and negative electrode materials, which can pollute the cleanroom environment if not cleaned for a long time, this embodiment proposes an AGV that can clean the floor. This floor-cleaning AGV can clean up debris and dust that falls onto the floor while handling rolls of material, ensuring that the cleanroom environment is not contaminated.

[0028] Reference Figure 1 , Figure 2The AGV transport vehicle that can clean the ground in this embodiment includes a transport vehicle body 1, a cleaning roller brush 2, a drive unit, a liquid storage tank 3, a waste liquid tank 5, and a vacuum motor 7, and may also include a drain pipe 16.

[0029] The transport vehicle body 1 of this embodiment adopts existing technology, including a base and two support columns 101 and 102 fixed on the base. A set of wheels for movement is provided on the base. Generally, when transporting the coil 17, the two ends of the support shaft inside the coil 17 are placed on the tops of the support columns 101 and 102, respectively. Limiting members for limiting the support shaft are provided on the tops of both the support columns 101 and 102. These structures are all existing and known, and will not be described in detail here. Generally, the support columns 101 and 102 are hollow, with only some supporting reinforcement structures, and the outer panels of the support columns 101 and 102 can be opened.

[0030] The cleaning roller brush 2 is rotatably mounted at one end of the bottom of the transport vehicle body 1, and the axis of the cleaning roller brush 2 is perpendicular to the traveling direction of the transport vehicle body 1, so as to ensure that the cleaning roller brush 2 can clean the ground during the movement of the transport vehicle body 1.

[0031] In this embodiment, to facilitate the installation of the cleaning roller brush 2, two opposing brackets 8 are fixedly installed at the bottom of the transport vehicle body 1. The brackets 8 are located on both sides of the cleaning roller brush 2, and a drive shaft 9 is provided between the brackets 8. The two ends of the drive shaft 9 are respectively rotatably connected to the two brackets 8, and the cleaning roller brush 2 is fixed on the drive shaft 9.

[0032] The drive unit is used to drive the cleaning roller brush 2 to rotate and clean the floor. In this embodiment, the drive unit includes a drive motor 10, two sprockets, and a transmission chain. The drive motor 10 is installed in the base, and the two sprockets are respectively fixed to the output shaft and drive shaft 9 of the drive motor 10. The transmission chain is fitted onto the two sprockets. Thus, when the transport vehicle body 1 is working, when the drive motor 10 is started, the cleaning roller brush 2 can be driven to rotate through the sprockets and transmission chain. When cleaning fluid (such as water) is sprayed onto the cleaning roller brush 2 to keep it moist, the cleaning roller brush 2 can clean the floor. Of course, in other embodiments, the drive unit can also be directly set as a single drive motor 10, which is connected to the drive shaft 9.

[0033] To prevent cleaning fluid from splashing out when the cleaning roller brush 2 is cleaning the floor, a cover plate 11 is also installed at the bottom of the transport vehicle body 1. The cover plate 11 is arranged along the axis of the cleaning roller brush 2 and covers the cleaning roller brush 2. A predetermined distance is maintained between the cover plate 11 and the cleaning roller brush 2 to ensure that the cleaning roller brush 2 can rotate freely.

[0034] To facilitate the delivery of cleaning fluid to the cleaning roller brush 2, a storage tank 3 containing the cleaning fluid is installed on the transport vehicle body 1. The height of the storage tank 3 is higher than that of the cleaning roller brush 2. The storage tank 3 is connected to a delivery pipe 4, with one end of the delivery pipe 4 extending away from the storage tank 3 and above the cleaning roller brush 2. Thus, under the action of gravity, the cleaning fluid in the storage tank 3 will be delivered to the cleaning roller brush 2 along the delivery pipe, keeping the cleaning roller brush 2 moist. The delivery speed of the cleaning fluid can be controlled by selecting a delivery pipe of appropriate diameter. Alternatively, a flow regulating valve can be directly installed on the delivery pipe to directly regulate the delivery speed of the cleaning fluid and control the on / off flow of the cleaning fluid. In this embodiment, the storage tank 3 is directly installed inside the support column 101. Thus, when it is necessary to add cleaning fluid to the storage tank 3, the outer side plate of the support column 101 can be opened directly to inject the cleaning fluid into the storage tank 3. Furthermore, to ensure the uniform distribution of the cleaning fluid on the cleaning roller brush 2, the end of the delivery pipe away from the storage tank 3 is arranged inside the cover plate 11, and the upper part of the delivery pipe is arranged along the axial direction of the cleaning roller brush 2. Multiple through holes are provided at intervals on the side of the delivery pipe facing the cleaning roller brush 2. The speed of the cleaning fluid flow can also be controlled by adjusting the size of the through hole diameter.

[0035] Because of dust on the ground, the cleaning fluid becomes dirty when the cleaning roller brush 2 cleans the floor. To collect the dirty fluid, a dirty fluid tank 5 and a vacuum motor 7 are installed on the transport vehicle body 1. The dirty fluid tank 5 is connected to a suction pipe 6, with the end of the suction pipe 6 away from the dirty fluid tank 5 located on one side of the cleaning roller brush 2. The air inlet of the vacuum motor 7 is connected to the dirty fluid tank 5. Under the action of the vacuum motor 7, a vacuum state is formed inside the dirty fluid tank 5, and the dirty fluid pipe sucks in the dirty fluid on the ground and transports it into the dirty fluid tank 5. Furthermore, a vertically arranged partition 14 is installed inside the dirty fluid tank 5, dividing the dirty fluid tank 5 into a sedimentation zone and a dirty fluid zone. One end of the suction pipe 6 extends into the sedimentation zone, and an overflow port 15 is provided on the partition 14. In this way, after the dirty fluid enters the dirty fluid tank 5, it first settles in the sedimentation zone. When the liquid level reaches the overflow port 15, the liquid overflows into the dirty fluid zone. To facilitate sewage discharge, a sewage pipe 16 is installed on the transport vehicle body 1. One end of the sewage pipe 16 is connected to the sewage area, and the other end is detachably connected to a plug (not shown in the figure). When the plug is opened, sewage can be discharged. In this embodiment, the sewage tank 5 is directly installed inside the support column 2 102. Thus, when it is necessary to clean the impurities settled in the sedimentation area of ​​the sewage tank 5, the outer side plate of the support column 2 102 can be opened directly for cleaning. Furthermore, to ensure that as much sewage as possible can be collected, the end of the suction pipe 6 away from the sewage tank 5 is arranged along the axial direction of the cleaning roller brush 2 at the bottom of the transport vehicle body 1, and multiple suction ports are spaced apart on the side of the sewage pipe facing the cleaning roller brush 2.

[0036] A lower scraper 12, which can contact the ground, is installed at the bottom of the transport vehicle body 1 near the bottom of the cleaning roller brush 2. The lower scraper 12 is arranged along the axial direction of the cleaning roller brush 2. When the transport vehicle body 1 moves, the lower scraper 12 can scrape up the residual dirt on the ground so that the dirt can be sucked away by the suction pipe 6. An upper scraper 13, which can contact the cleaning roller brush 2, is fixed on the side of the cover plate 11 near the lower scraper 12. The upper scraper 13 is arranged along the axial direction of the cleaning roller brush 2. The infusion pipe 4 is located on the side of the upper scraper 13 away from the lower scraper 12. In this way, when the cleaning roller brush 2 rotates, the upper scraper 13 can scrape off the residual dirt on the cleaning roller brush 2 so that the dirt can be sucked away by the suction pipe 6.

[0037] Combination Figure 2 The working principle of the AGV transport vehicle for cleaning the ground in this embodiment will be explained.

[0038] Because the positive and negative electrode materials on the surface of the roll material 17 are exposed, material debris will fall off. During the AGV transport vehicle's handling of the roll material 17, the drive motor 10 and vacuum motor 7 are turned on. At this time, the cleaning roller brush 2 rotates in the same direction as the traveling wheels at the bottom of the transport vehicle body 1, moving forward. The cleaning liquid in the storage tank 3 flows along the conveying pipe under the action of gravity and flows out from the through hole of the conveying pipe, dripping onto the cleaning roller brush 2. The wet cleaning roller brush 2 rotates to clean the ground. At the same time, the dirty liquid generated during cleaning is sucked into the sedimentation area of ​​the dirty liquid tank 5 along the suction pipe 6. Solids settle in the sedimentation area, and after the liquid reaches a certain height, it flows into the dirty liquid area along the overflow port 15. In addition, the lower scraper 12 can scrape up the dirty liquid remaining on the ground, and the upper scraper 13 can scrape off the dirty liquid remaining on the cleaning roller brush 2 so that the dirty liquid can be sucked away by the suction pipe 6. In this way, the cleaning work of the ground can be completed while transporting goods, effectively ensuring that the environment of the clean room is not polluted, while avoiding the impact of manual cleaning on the workshop environment.
