Description

Technical Field

[0001] This utility model belongs to the field of dangerous goods transportation, and specifically relates to an automatic transport device for acid barrels. Background Technology

[0002] Blue industrial plastic drums, commonly known as acid drums, are plastic packaging containers widely used in semiconductor and other industries. Their design balances safety and environmental friendliness, making them particularly suitable for the storage and transportation of hazardous chemicals or materials requiring special protection. The design and function of acid drums may vary depending on the application. Particularly in semiconductor plants, acid drums may need corrosion-resistant properties to prevent acid from corroding the container material. When using the solution inside the acid drum, it needs to be transported; therefore, an automated and safe transport device for acid drums is required.

[0003] In existing technologies, automated acid drum transport devices are prone to bumping during transport, leading to splashing of the liquid inside the drums. Simultaneously, manual handling poses safety hazards. Therefore, the transfer of acid drums requires special attention to safety and environmental protection. Furthermore, relevant safety regulations and standards must be followed during transfer to ensure the safety and reliability of transport vehicles and loading facilities. Fire prevention and explosion-proof measures must be implemented, and appropriate transport routes and times must be selected. In addition, transport personnel should receive professional training and assessment, possessing the relevant knowledge and skills. During transport, operating procedures must be strictly followed to ensure correct and standardized operation, avoiding operational errors that could lead to accidents. Only by doing these things well can the safe transport of acid drums be ensured, protecting the safety of personnel and the environment. However, the existing acid drum transportation process has several drawbacks. Inappropriate vehicle selection and unreasonable capacity allocation lead to resource waste. Non-compliant operations by personnel during transport, such as turning too fast, using excessively small turning radii, or unevenly distributing cargo, pose a risk of vehicle overturning. Furthermore, the transfer of acid drums is prone to chemical leaks due to road bumps or vehicle collisions, which, if significant, could severely impact the surrounding environment and people. Leaked pollutants may spread through the air and other chemical forms, and some chemicals have irritating odors that can affect workers and the surrounding environment. There is also the risk of operators mis-scanning or misidentifying barcodes, resulting in the transfer of the wrong acid drums. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-4As shown, an automatic acid barrel transport device includes an unmanned transport device 1. The unmanned transport device 1 includes a frame 2, on which a control cabinet 16, an acid barrel clamping mechanism, a transport carrying mechanism, a waste liquid collection mechanism, a ventilation mechanism, a monitoring mechanism, a data acquisition mechanism, and an audible and visual alarm device 7 are mounted. The acid barrel clamping mechanism includes two sets of opposing gripper assemblies 11, which are respectively located on the front and rear sides of the frame 2. The transport carrying mechanism includes several transport rollers 9 arranged in parallel, which are located below the acid barrel clamping mechanism. The waste liquid collection mechanism includes components installed on the transport carrying mechanism. The structure includes a waste liquid collection tank 5 below the frame 2; an exhaust system including a fan 14 located at the rear of the frame 2; a monitoring system including a gas detection device 12 located on the frame 2, which is connected to the control cabinet 16; a data acquisition system including a barcode reader 17 for identifying electronic barcode information on the acid barrel and a vision camera 13 for acquiring the location information of the acid barrel, both the barcode reader 17 and the vision camera 13 are located on the frame 2 and are both connected to the control cabinet 16; the control cabinet 16 controls and connects to an audible and visual alarm device 7, and the control cabinet 16 is equipped with a wireless signal transmission device for uploading alarm signals to the upper system. This design enables an automated, unmanned transport device to replace traditional manual transport methods, facilitating the establishment of an automated conveying system. This system automates the transfer of acid drums between various chemical equipment within the workshop, freeing up manpower, reducing operator hours and workload, lowering labor costs, and improving economic efficiency. Furthermore, it enhances transport safety by effectively reducing the number of operators and their skill requirements, minimizing data loss and discrepancies between physical and digital data caused by manual operation. It also effectively reduces the risk of cargo leakage and potential injuries or fatalities during manual operation, further ensuring personnel safety.

[0021] The acid barrel clamping mechanism is used to secure the acid barrels during transport. The gripper assembly 11 in the acid barrel clamping mechanism includes a lead screw fixed to the frame 2. A push seat 23 is provided on the slider 22 of the lead screw. The push seat 23 is connected to a fixed rod 26 and a flexible buffer structure 24. The flexible buffer structure 24 is located on one side of the fixed rod 26. A fixed sleeve 25 is connected to the end of the flexible buffer structure 24 away from the push seat 23. One end of the fixed rod 26 extends into the fixed sleeve 25. An arc-shaped clamping plate 18 is connected to the fixed sleeve 25. Specifically, the flexible buffer structure 24 can be a compression spring. A first drive motor 19 is provided on one side of the lead screw. A reduction gearbox 20 is connected to the shaft of the first drive motor 19. The output end of the reduction gearbox 20 is connected to the lead screw 21 of the lead screw. The control cabinet 16 is electrically connected to the first drive motor 19. The flexible buffer structure 24 and the fixed sleeve 25 are integrated, and the sum of the length of the flexible buffer structure 24 when uncompressed and the length of the fixed sleeve 25 is greater than the length of the fixed rod 26. This design controls the operation of the first drive motor 19 via the control cabinet 16. The first drive motor 19 drives the lead screw, and the slider 22 of the lead screw drives the push seat 23 to move forward and backward, allowing the clamping plates 18 of the two sets of gripper assemblies 11 to move closer or further apart, thereby fixing the acid drum during transport. In particular, the flexible buffer structure 24 in the acid drum clamping mechanism ensures that the acid drum is less affected by the operating speed and movement of the unmanned transport device 1 during transport, thereby reducing the shaking of chemicals inside the acid drum, providing anti-shake protection, and maintaining sufficient stability during chemical transport. Furthermore, a distance detection device 27 for detecting the compression stroke of the flexible buffer structure 24 is provided on one side of the clamping plate 18. The distance detection device 27 is electrically connected to the control cabinet 16. The distance detection device 27 can detect the spring compression stroke. When the spring compression stroke exceeds the preset shaking threshold inside the control cabinet 16, it indicates that the acid tank is shaking too much and there is a risk. The control cabinet 16 then controls the audible and visual alarm device 7 to sound an alarm and transmits the alarm signal to the upper system via a wireless signal transmission device. Specifically, the distance detection device 27 can be a pull rope displacement sensor, which is installed on the clamping plate 18 and located inside the fixed sleeve 25. One end of the pull rope of the pull rope displacement sensor is connected to the fixed rod 26; or, the distance detection device 27 can also be a displacement sensor such as a laser displacement sensor.

[0022] The transport and carrying mechanism is used to receive, transfer, and carry acid drums during the transfer process. The transport roller 9 in the transport and carrying mechanism is located below the center of the two gripper assemblies 11, and the transport direction of the transport roller is perpendicular to the travel direction of the frame 2. The transport and carrying mechanism also includes a mounting frame, to which the transport roller 9 is rotatably connected. A second drive motor is located on one side of the mounting frame, and the shaft of the second drive motor is connected to a drive wheel. A driven wheel is located on one side of the transport roller 9, and the drive wheel and the driven wheel are connected by a belt. The control cabinet 16 is electrically connected to the second drive motor, thereby facilitating the receiving and transfer of acid drums. Specifically, the roller surface is provided with anti-slip textures.

[0023] The waste liquid collection mechanism is used to collect leaked liquid from acid tanks during transport. The waste liquid collection tank 5 within the mechanism is equipped with a level detection device 15 to monitor the amount of waste liquid within it. A control cabinet 16 is connected to the level detection device 15. The level detection device 15 detects the amount of waste liquid collected in the waste liquid collection tank 5. When the amount of waste liquid exceeds a preset waste liquid threshold in the control cabinet 16, it indicates excessive leakage from the acid tank, posing a risk. The control cabinet 16 then activates an audible and visual alarm device 7 to sound an alarm and transmits the alarm signal to the upper-level system via a wireless signal transmission device. Specifically, the length of the waste liquid collection tank 5 is not less than the length of the transport roller 9, and the width of the waste liquid collection tank 5 is the same as the width of the frame 2. The level detection device 15 can be a photoelectric level sensor or other level sensor. Furthermore, to further improve the effectiveness of the waste liquid collection mechanism, a waste liquid collection container can be installed on the frame 2. The waste liquid collection tank 5 is connected to the waste liquid collection container, and a level sensor is installed inside the waste liquid collection container, connected to the control cabinet 16.

[0024] The monitoring system is used to detect volatile gases generated by acid tank leaks during acid tank transfer. The gas detection device 12 in the monitoring system can be an oxygen sensor used to detect the oxygen content within the unmanned transport device 1; that is, when a large amount of volatile gas is generated by the acid tank leak, the oxygen content within the unmanned transport device 1 will decrease. Alternatively, a gas sensor corresponding to the liquid stored in the acid tank can be used. For example, if the acid tank stores ammonia, hydrochloric acid, or hydrogen peroxide, the gas detection device 12 can use an ammonia sensor, a hydrogen chloride sensor, or an oxygen sensor, respectively. Furthermore, when the amount of volatile gas detected by the gas detection device 12 exceeds the preset gas threshold in the control cabinet 16, it indicates excessive acid tank leakage and a potential risk. The control cabinet 16 then activates the audible and visual alarm device 7 to sound an alarm and transmits the alarm signal to the upper-level system via a wireless signal transmission device.

[0025] The exhaust system is used to discharge volatile gases generated by acid tank leakage during acid tank transfer. The fan 14 in the exhaust system includes a third drive motor, and the control cabinet 16 is electrically connected to the third drive motor. When the monitoring mechanism detects that a certain gas inside the unmanned transport device 1 exceeds the preset gas threshold in the control cabinet 16, the control cabinet 16 controls the unmanned transport device 1 to move to a designated space and controls the third drive motor to rotate the fan blades of the fan 14, allowing the exhaust gas to be discharged quickly. Furthermore, a vent is provided on the rear side of the frame 2, and the fan 14 is located at the vent. Specifically, a dustproof net 8 can be installed at the vent to reduce the impact of dust on the fan 14. Alternatively, an openable baffle can be installed at the vent to block exhaust gas leakage. The baffle can be connected to the outer wall of the frame 2 via an electric slide rail, and the control cabinet 16 is electrically connected to the electric slide rail.

[0026] To facilitate the transport and carrying of acid barrels by the unmanned transport device 1, an acid barrel receiving cavity is provided in the middle of the frame 2 of the unmanned transport device 1. Two sets of gripper assemblies 11 are respectively arranged on both sides of the acid barrel receiving cavity, and the transport roller 9 is arranged below inside the acid barrel receiving cavity. A movable shell 3 for closing the acid barrel receiving cavity is provided on the frame 2. The movable shell 3 is connected to the rear of the frame 2 through a linear guide rail 4. The control cabinet 16 is electrically connected to the linear guide rail, so that the control cabinet 16 can control the forward and backward movement of the movable shell 3 through the linear guide rail 4 to close or open the acid barrel receiving cavity. Specifically, the cross-section of the movable shell 3 is U-shaped. Two sets of linear guide rails 4 are arranged in parallel on the rear side of the top of the frame 2. The slider of the linear guide rail 4 is connected to the inner side wall of the top of the movable shell 3.

[0027] The acid drum limiting mechanism is used to restrict the position of the acid drum during the transfer process. There are two sets of acid drum limiting mechanisms, each located on one side of the transport carrier mechanism. Each limiting mechanism includes two vertically arranged lifting devices, located on the front and rear sides of the frame 2 respectively. A horizontally arranged limiting rod 6 is provided between the lifting ends of the two lifting devices. The control cabinet 16 controls and connects to the lifting devices. When the acid drum is being transferred, the control cabinet 16 can control the lifting end of the lifting device to rise, raising the limiting rod 6 above the transport roller 9 in the transport carrier mechanism, thereby limiting the position of the acid drum. When it is necessary to receive or transfer the acid drum, the control cabinet 16 can control the lifting end of the lifting device to fall, lowering the limiting rod 6 below the transport roller 9 in the transport carrier mechanism. This allows the transport roller 9 in the transport carrier mechanism to rotate, moving the acid drum and enabling the receipt or transfer of the acid drum. Specifically, a protective cover 10 is provided on the outside of the lifting device to protect the lifting device. The protective cover 10 located on the rear side of the frame 2 is provided with a strip-shaped notch on the side of the mobile car body 3 for passing through the mobile car body 3, so as to avoid affecting the forward and backward movement of the mobile car body 3.

[0028] To facilitate direct control of the unmanned transport device by operators, a control panel is located on the front of the chassis. The control panel has control buttons, which are electrically connected to the control cabinet 16. The control buttons include start, pause, and emergency stop buttons.

[0029] The data acquisition mechanism is used to identify and read the electronic barcode information on the acid drums, as well as to collect basic material information and location information of the acid drums. Specifically, there are three barcode readers 17, which are respectively located at the upper front, middle front, and middle rear of the acid drum receiving cavity; the vision camera 13 is located on the upper rear side of the frame 2, with its shooting position facing the acid drum receiving cavity. Both the barcode readers 17 and the vision camera 13 are electrically connected to the control cabinet 16. Thus, the barcode readers 17 read the electronic barcode information on the acid drums and upload it to the control cabinet 16. The control cabinet 16 performs material identification on the transported acid drums. At the same time, the vision camera 13 can collect the location information of the acid drums, thereby reducing the occurrence of data loss due to manual operation and discrepancies between the actual product and the data.

[0030] The audible and visual alarm device 7 is used to alert workshop personnel. The audible and visual alarm device 7 is located on the upper front side of the chassis 2, and the control cabinet 16 is electrically connected to the audible and visual alarm device 7. Specifically, the audible and visual alarm device 7 uses an audible and visual alarm unit. Alternatively, the audible and visual alarm device 7 uses an LED light and a buzzer.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
