Description

Technical Field

[0001] This application relates to the field of warehousing and logistics technology, specifically to an automated guided vehicle. Background Technology

[0002] When the conveyor belt of the automated guided vehicle connects with the belt of the processing device, the workpiece is prone to shaking during the connection process due to the speed difference between the conveyor belt and the belt. This can cause the workpiece to slip on the belt or conveyor belt and fall or even be damaged. Utility Model Content

[0003] Therefore, it is necessary to provide an automated guided vehicle that can reduce the risk of workpiece slippage in order to address the above problems.

[0004] An automated guided vehicle (AGV) includes a vehicle body, a conveying assembly, and a limiting assembly, wherein the conveying assembly and the limiting assembly correspond one-to-one.

[0005] The vehicle body has a storage bin and an inlet / outlet communicating with the storage bin. The conveying assembly includes a conveyor belt, which is disposed in the storage bin and used to convey workpieces to or from the storage bin along the length of the vehicle body. The limiting assembly includes multiple pairs of limiting members, all of which are disposed in the storage bin and arranged sequentially along the height of the vehicle body. Each pair of limiting members is arranged along the width of the vehicle body on opposite sides of all the conveyor belts in the corresponding conveying assembly, and each pair of limiting members defines a limiting channel for limiting the workpiece.

[0006] In some embodiments, the limiting channel includes a guide section and a limiting section. The guide section and the limiting section are arranged and connected along the length direction of the vehicle body. The guide section is used to guide the workpiece into the limiting channel. In the direction from the guide section to the limiting section, the width of the guide section gradually decreases, while the width of the limiting section remains unchanged.

[0007] In some embodiments, the limiting member has a limiting surface facing the limiting channel. The limiting surface includes a first sub-surface and a second sub-surface. The first sub-surface and the second sub-surface are arranged and connected along the length direction of the vehicle body. The first sub-surface is an inclined surface and gradually approaches the corresponding conveyor belt in the direction from the guide section to the limiting section. The second sub-surface is a straight surface. The first sub-surface of each pair of limiting members defines the guide section, and the second sub-surface of each pair of limiting members defines the limiting section.

[0008] In some embodiments, the limiting component includes two pairs of limiting members, wherein one pair of limiting members is disposed on the top wall of the storage bin, and the other pair of limiting members is disposed on the bottom wall of the storage bin.

[0009] In some embodiments, the conveying components and the limiting components are multiple sets, and all sets of the conveying components and all sets of the limiting components are spaced apart along the width direction of the vehicle body.

[0010] In some embodiments, the conveyor assembly comprises multiple conveyor belts, all of which are spaced apart along the width direction of the vehicle body, and all of which cooperate to convey the same workpiece.

[0011] In some embodiments, the conveying assembly further includes a rotating shaft, a conveying drive wheel, a conveying driven wheel, and a conveying timing belt. The conveying drive wheel, the conveying driven wheel, and the conveying timing belt correspond one-to-one with the conveyor belt. The conveying drive wheel is disposed on the rotating shaft. The conveying timing belt is sleeved between the corresponding conveying drive wheel and the conveying driven wheel, and the conveying timing belt is connected between the corresponding conveying drive wheel and the conveying driven wheel. A section of the conveying timing belt located on the top side of the corresponding conveying drive wheel and the conveying driven wheel forms the conveyor belt.

[0012] In some embodiments, the automated guided vehicle further includes a base and a water tank. The base is used to mount the vehicle body and the water tank. The outlet of the water tank is configured to open when the humidity in the workshop where the automated guided vehicle is located is lower than a first set humidity value, and is configured to close when the humidity in the workshop is higher than a second set humidity value, wherein the first set humidity value is lower than the second set humidity value.

[0013] In some embodiments, a humidity detection element is also included, which is disposed on the base or the vehicle body, and is used to detect the humidity of the workshop.

[0014] In some embodiments, the automated guided vehicle further includes multiple pairs of wheels, all pairs of wheels are spaced apart along the length of the vehicle body, and each pair of wheels is spaced apart along the width of the vehicle body, all the wheels forming a placement space, and the water tank is located within the placement space.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] In the aforementioned automated guided vehicle (AGV), all pairs of limiting components are located within the storage bin and arranged sequentially along the height of the vehicle body. Furthermore, each pair of limiting components is positioned along the width of the vehicle body on opposite sides of all conveyor belts in the corresponding conveying assembly, defining a limiting channel for the workpiece. Therefore, during the process of workpieces entering and exiting the storage bin and during transport within the storage bin, the workpiece is positioned at multiple locations along the height of the vehicle body by paired limiting components along the width of the vehicle body. This design reduces the possibility of workpiece vibration when the conveyor belt engages with the processing device's belt, thereby better controlling the stability of workpieces entering and exiting the storage bin and reducing the risk of workpieces falling due to belt or conveyor slippage.

[0030] When the conveyor belt of an Automated Guided Vehicle (AGV) docks with the belt of a processing device, the workpiece is prone to shaking during the docking process due to the speed difference between the conveyor belt and the belt. This can cause the workpiece to slip on the belt or conveyor belt and fall or even be damaged.

[0031] Please see Figure 1 To alleviate the above problems, this application provides an automated guided vehicle 1, which includes a vehicle body 10, a conveying assembly 20, and a limiting assembly 30, with the conveying assembly 20 and the limiting assembly 30 corresponding one-to-one. The vehicle body 10 has a storage bin 11 and an inlet / outlet 12 communicating with the storage bin 11. The conveying assembly 20 includes a conveyor belt 21, which is disposed in the storage bin 11 and used to convey workpieces in or out of the storage bin 11 along the length direction X of the vehicle body 10. The limiting assembly 30 includes multiple pairs of limiting members 31, all of which are disposed in the storage bin 11 and arranged sequentially along the height direction Z of the vehicle body 10. Each pair of limiting members 31 is arranged along the width direction Y of the vehicle body 10 on opposite sides of all conveyor belts 21 in the corresponding conveying assembly 20, and each pair of limiting members 31 defines a limiting channel 311 for limiting the workpiece.

[0032] Specifically, the workpiece can be a battery cell, a basket that carries the battery cell, or other structures, which can be set according to production needs.

[0033] The vehicle body 10 is typically a hollow cuboid shape, with a storage bin 11 inside. The storage bin 11 is used to carry and store workpieces during the process of the automated guided vehicle 1 transporting workpieces. The inlet and outlet 12 are located on one end face of the vehicle body 10 along the length direction X. The inlet and outlet 12 are connected to the storage bin 11 and are used to ensure that workpieces can enter and exit the storage bin 11.

[0034] The conveying component 20 and the limiting component 30 are in one-to-one correspondence, and the number of conveying components 20 and limiting components 30 can be set according to requirements. For example, the conveying component 20 and the limiting component 30 are one set, or the conveying component 20 and the limiting component 30 are at least two sets.

[0035] In some embodiments, the conveying assembly 20 and the limiting assembly 30 are multiple sets, and all sets of conveying assemblies 20 and all sets of limiting assemblies 30 are arranged at intervals along the width direction Y of the vehicle body 10. Figure 1 For example, there are two sets of conveying components 20 and two sets of limiting components 30, and the two sets of conveying components 20 and the two sets of limiting components 30 are arranged at intervals along the width direction Y of the vehicle body 10. In this way, multiple workpieces can be conveyed into the storage bin 11 through multiple sets of conveying components 20 and multiple sets of limiting components 30 in the same time period, which helps to improve the production efficiency of workpieces.

[0036] The conveying assembly 20 includes a conveyor belt 21, which is used to dock with a belt and to receive workpieces conveyed by the belt, or to convey workpieces to the belt.

[0037] Specifically, after the workpiece completes the previous processing step under the action of the previous processing device, the conveyor belt 21 connects with the belt of the previous processing device, so that the workpiece that has completed the previous processing step can be transferred onto the conveyor belt 21 and transported to the storage bin 11 for storage, thereby reducing the risk of the workpiece falling off the automated guided vehicle 1. When the workpiece is transported to the next processing device under the action of the automated guided vehicle 1, the conveyor belt 21 connects with the belt of the next processing device, so that the conveyor belt 21 can transfer the workpiece in the storage bin 11 onto the belt of the next processing device, so as to facilitate the subsequent processing of the workpiece by the next processing device.

[0038] Therefore, the docking of conveyor belt 21 with the belt includes docking conveyor belt 21 with the belt of the previous processing device, and also docking conveyor belt 21 with the belt of the next processing device. When conveyor belt 21 docks with the belt of the previous processing device, the workpiece on the belt of the previous processing device is transported to the storage bin 11 via conveyor belt 21. When conveyor belt 21 docks with the belt of the next processing device, the workpiece in the storage bin 11 is transported to the belt of the next processing device via conveyor belt 21. In both docking scenarios, there will be issues due to the speed difference between the docking of conveyor belt 21 and the belt.

[0039] All pairs of limiting members 31 of the limiting assembly 30 are disposed within the storage bin 11 and are arranged sequentially along the height direction Z of the vehicle body 10. Furthermore, each pair of limiting members 31 is arranged along the width direction Y of the vehicle body 10 on opposite sides of all conveyor belts 21 in the corresponding conveying assembly 20, and each pair of limiting members 31 defines a limiting channel 311 for limiting the workpiece. Therefore, during the process of workpiece entering and exiting the storage bin 11 and during transportation within the storage bin 11, the workpiece is limited by pairs of limiting members 31 arranged along the width direction Y of the vehicle body 10 at multiple positions along the height direction Z of the workpiece. This design reduces the possibility of workpiece vibration when the conveyor belt 21 connects with the belt of the processing device, thereby better controlling the stability of the workpiece entering and exiting the storage bin 11 and reducing the risk of workpiece falling due to slippage of the belt or conveyor belt 21.

[0040] As an example, the limiting component 30 may include two or more pairs of limiting elements 31.

[0041] In some embodiments, the limiting component 30 includes two pairs of limiting members 31, one pair of limiting members 31 being disposed on the top wall of the storage bin 11, and the other pair of limiting members 31 being disposed on the bottom wall of the storage bin 11. Each pair of limiting members 31 can be fixed to its disposed top or bottom wall by welding, bonding, or other installation methods. By providing two pairs of limiting members 31, the risk of workpiece vibration when the conveyor belt 21 docks with the belt can be reduced, while the number of limiting members 31 can also be reduced, thereby reducing the manufacturing cost and weight of the automated guided vehicle 1. Moreover, the fact that one pair of limiting members 31 is disposed on the top wall of the storage bin 11 and the other pair of limiting members 31 is disposed on the bottom wall of the storage bin 11 also facilitates the installation of the pairs of limiting members 31.

[0042] In some embodiments, the limiting channel 311 includes a guide section 3111 and a limiting section 3112. The guide section 3111 and the limiting section 3112 are arranged and connected along the length direction X of the vehicle body 10. The guide section 3111 is used to guide the workpiece into the limiting channel 311. In the direction from the guide section 3111 to the limiting section 3112, the width of the guide section 3111 gradually decreases, while the width of the limiting section 3112 remains unchanged.

[0043] Specifically, the width of guide segment 3111 refers to its dimension in the width direction Y of vehicle body 10, and the width of limiting segment 3112 refers to its dimension in the width direction Y of vehicle body 10. The width of limiting segment 3112 is equal to the minimum width of guide segment 3111.

[0044] During the process of connecting conveyor belt 21 with the belt of the previous processing device and transferring the belt of the previous processing device onto conveyor belt 21, initially, the workpiece enters from the wider end of guide section 3111. Then, as the width of guide section 3111 gradually narrows, it guides the workpiece into storage bin 11 while simultaneously strengthening its limiting effect, further reducing the possibility of workpiece vibration during connection between conveyor belt 21 and the belt of the previous processing device. Meanwhile, the width of limiting section 3112 remains constant. Therefore, as the workpiece is positioned on conveyor belt 21 and further conveyed into storage bin 11, limiting section 3112 consistently applies a strong and stable limiting effect, thereby improving the stability of workpiece conveying.

[0045] Furthermore, in some embodiments, the limiting member 31 has a limiting surface 312 facing the limiting channel 311. The limiting surface 312 includes a first sub-surface 3121 and a second sub-surface 3122. The first sub-surface 3121 and the second sub-surface 3122 are arranged and connected along the length direction X of the vehicle body 10. The first sub-surface 3121 is an inclined surface and gradually approaches the corresponding conveyor belt 21 in the direction from the guide section 3111 to the limiting section 3112. The second sub-surface 3122 is a straight surface. The first sub-surface 3121 of each pair of limiting members 31 defines the guide section 3111, and the second sub-surface 3122 of each pair of limiting members 31 defines the limiting section 3112. This method of forming the guide section 3111 and the limiting section 3112 is simple and easy to form.

[0046] Of course, the formation of the guide segment 3111 is not limited to the one mentioned above. In some other embodiments, the first sub-surface 3121 can also be an arc surface, and the two arc surfaces of the paired limiting members 31 define and form the limiting segment 3112.

[0047] In some embodiments, there are multiple conveyor belts 21 in the conveying assembly 20. All the conveyor belts 21 in the conveying assembly 20 are spaced apart along the width direction Y of the vehicle body 10, and all the conveyor belts 21 in the conveying assembly 20 cooperate to convey the same workpiece.

[0048] Specifically, the conveyor belts 21 in different conveying assemblies 20 are used to convey different workpieces, and all conveyor belts 21 in the same conveying assembly 20 are used to convey the same workpiece. By setting multiple conveyor belts 21 in the conveying assembly 20, and having all conveyor belts 21 in the same conveying assembly 20 cooperate to convey the same workpiece, the stability of workpiece conveying can be improved.

[0049] In some embodiments, the conveying assembly 20 further includes a rotating shaft 22, a conveying drive wheel 23, a conveying driven wheel, and a conveying timing belt 24. The conveying drive wheel 23, the conveying driven wheel, and the conveying timing belt 24 are all corresponding one-to-one with the conveying belt 21. The conveying drive wheel 23 is disposed on the rotating shaft 22. The conveying timing belt 24 is sleeved between the corresponding conveying drive wheel 23 and the conveying driven wheel, and the conveying timing belt 24 is connected between the corresponding conveying drive wheel 23 and the conveying driven wheel. A section of the conveying timing belt 24 located on the top side of the corresponding conveying drive wheel 23 and the conveying driven wheel forms the conveying belt 21.

[0050] In actual operation, within the same conveying assembly 20, the rotating shaft 22 rotates, transmitting power through the conveying drive wheel 23 to the conveying timing belt 24, thereby enabling the conveyor belt 21 to drive the workpiece for conveying.

[0051] In this application, by setting a rotating shaft 22, the power on the rotating shaft 22 can be transmitted to all the conveyor belts 21 in the same conveying assembly 20. This design has a simple structure and fewer parts, which helps to reduce the manufacturing cost of the automated guided vehicle 1.

[0052] As an example, the conveying assembly 20 may also include a conveying motor, which is directly connected to the rotating shaft 22 and is used to drive the rotating shaft 22 to drive the conveying drive wheel 23 to rotate, thereby realizing the operation of conveying workpieces by the conveyor belt 21.

[0053] As an example, the conveying assembly 20 may further include a drive pulley, a driven pulley, and a synchronous belt. The conveying motor is connected to the drive pulley, the driven pulley is mounted and fixed on the shaft 22, and the synchronous belt is mounted on the drive pulley and the driven pulley. When the conveying motor is working, its power is transmitted to the conveyor belt 21 through the drive pulley, the synchronous belt, the driven pulley, the shaft 22, and the drive pulley 23, thereby driving the workpiece to move.

[0054] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the automated guided vehicle (AGV) further includes a base 40 and a water tank 50. The base 40 is used to mount the vehicle body 10 and the water tank 50. The outlet of the water tank 50 is configured to open when the humidity in the workshop where the AGV 1 is located is lower than a first set humidity value, and is configured to close when the humidity in the workshop is higher than a second set humidity value, wherein the first set humidity value is lower than the second set humidity value.

[0055] Specifically, the vehicle body 10 is mounted on the top side of the base 40, and the water tank 50 is mounted on the bottom side of the base 40.

[0056] During the production and processing of workpieces, the workshop usually needs to be sprayed with water regularly to adjust the humidity of the workshop to ensure that the humidity of the workshop for workpiece production and processing can meet the requirements.

[0057] In traditional production processes, manual watering is usually used. However, manual watering is subject to many variables, the amount of water sprayed cannot be precisely controlled, and the workshop area is large, making manual watering time-consuming and labor-intensive.

[0058] In this application, when the humidity in the workshop where the automated guided vehicle 1 is located is lower than the first set humidity value, it indicates that the workshop is relatively dry. At this time, the water outlet opens, and the water stored in the water tank 50 is sprayed out through the water outlet to humidify the workshop, thereby increasing the humidity. When the humidity in the workshop where the automated guided vehicle 1 is located is higher than the second set humidity value, it indicates that the workshop is relatively humid. At this time, the water outlet closes, and the water tank 50 stops discharging water.

[0059] The first and second humidity settings can be set according to actual production needs.

[0060] As an example, a cover for opening and closing the water outlet is provided at the outlet of the water tank 50, and the water tank 50 also has a drive motor for driving the cover to open and close the water outlet. The drive motor drives the cover to translate or rotate relative to the water tank 50, thereby realizing the operation of opening and closing the water outlet. The body 10 of the automated guided vehicle 1 has its own control system, which is electrically connected to the drive motor and controls the drive motor to work so that the cover can open and close the water outlet.

[0061] As mentioned above, in this application, by designing a water tank 50, automatic watering can be achieved during the movement of the automated guided vehicle 1. This design eliminates the need for manual operation and reduces workshop production costs.

[0062] In some embodiments, the automated guided vehicle 1 further includes a humidity detection element, which is disposed on the base 40 or the vehicle body 10, and is used to detect the humidity of the workshop.

[0063] As an example, the humidity detection device is electrically connected to the control system. The humidity detection device is used to feed back the detected humidity to the control system. The control system compares the humidity fed back by the humidity detection device with a first set humidity value and a second set humidity value, and controls the drive motor to drive the cover to open or close the water outlet according to the comparison result.

[0064] As an example, the automated guided vehicle 1 has a display screen on which the humidity detected by the humidity sensor is displayed. Based on the displayed humidity, the operator controls the cover to open or close the water outlet.

[0065] In this application, by designing a humidity detection device, the humidity of the workshop can be automatically and accurately obtained, which facilitates timely adjustment of the humidity in the workshop and improves the production yield of the workpiece.

[0066] In some embodiments, the automated guided vehicle 1 further includes multiple pairs of wheels 60. All pairs of wheels 60 are spaced apart along the length direction X of the vehicle body 10, and each pair of wheels 60 is spaced apart along the width direction Y of the vehicle body 10. All wheels 60 surround a placement space, and the water tank 50 is located within the placement space.

[0067] The traveling wheels 60 facilitate the movement of the automated guided vehicle 1 on the workshop floor. The automated guided vehicle 1 also includes a driving assembly that rotates the traveling wheels 60. The driving assembly is electrically connected to a control system, which controls the driving assembly to drive the traveling wheels 60, thus moving the automated guided vehicle 1 along a preset path. These are conventional technical methods in the field and will not be described in detail here.

[0068] The water tank 50 is located within the space formed by all the traveling wheels 60, so that the weight of the water tank 50 can be distributed relatively evenly along the length direction X and the width direction Y of the vehicle body 10 on the bottom side of the base 40. In this way, the weight distribution of the automatic guided vehicle 1 is more even, making it more stable when walking and transporting workpieces.

[0069] In some embodiments, in the height direction Z of the vehicle body 10, the traveling wheels 60 protrude from the bottom side of the water tank 50 relative to the water tank 50. Therefore, when the traveling wheels 60 contact the workshop floor, the water tank 50 is spaced apart from the floor, thereby preventing the water tank 50 from scraping against the floor during the movement of the automated guided vehicle 1, ensuring that the water tank 50 will not wear out, and thus extending the service life of the water tank 50.

[0070] In the aforementioned automated guided vehicle 1, all pairs of limiting members 31 of the limiting assembly 30 are disposed within the storage bin 11 and arranged sequentially along the height direction Z of the vehicle body 10. Furthermore, each pair of limiting members 31 is arranged along the width direction Y of the vehicle body 10 on opposite sides of all conveyor belts 21 in the corresponding conveying assembly 20, and each pair of limiting members 31 defines a limiting channel 311 for limiting the workpiece. Therefore, during the process of workpieces entering and exiting the storage bin 11 and during transportation within the storage bin 11, the workpieces at multiple positions along the height direction Z of the vehicle body 10 are limited by pairs of limiting members 31 along the width direction Y of the vehicle body 10. This design reduces the possibility of workpiece vibration when the conveyor belt 21 connects with the belt of the processing device, thereby better controlling the stability of workpieces entering and exiting the storage bin 11 and reducing the risk of workpieces falling due to slippage of the belt or conveyor belt 21.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
