Description

Technical Field

[0001] This application relates to the field of automotive refueling technology, and in particular to a visual refueling device and system for automotive liquid media. Background Technology

[0002] During the production and use of automobiles, various liquid media need to be added to the vehicle, generally including the following: adding engine oil: adding engine lubricating oil, usually done during maintenance; adding coolant: adding antifreeze or coolant to maintain normal engine temperature; adding windshield washer fluid: adding washer fluid to the windshield washer fluid reservoir; adding refrigerant: adding refrigerant to the air conditioning system.

[0003] The existing technology involves a car lubricating oil filling device, which includes a piston and lubricating oil stored inside a tank. The lubricating oil in the tank is pressurized by driving the piston to move up and down, and a visual pointer is set in the tank so that when the lubricating oil in the tank is filled into the car through the delivery pipe, it is convenient for manual inspection of the lubricating oil in the car. However, when adding various liquid media to automobiles, many liquid media are volatile, such as windshield washer fluid and antifreeze, or easily oxidized, such as engine oil. Furthermore, engine oil can also cause its components to separate if left to stand for a long time. Therefore, it is necessary to seal and protect the liquid media stored inside the tank. However, the existing automobile filling system does not provide sufficient airtight protection for the liquid storage, and the internal liquid media are prone to deterioration or separation, resulting in a significant decrease in the performance of the liquid media added into the automobile. Summary of the Invention

[0004] This application provides a visual dispensing device and system for automotive liquid media, which can solve the problems of insufficient airtightness of existing automotive dispensing systems for storing liquid media, easy stratification and deterioration of liquid media, and performance degradation.

[0005] The technical solution of this application is as follows: A visual dispensing device for automotive liquid media, comprising: A pneumatic filling device, comprising a storage tank for storing a liquid medium and a pumping device for pumping out protective gas, wherein a pressurization zone is provided between the inner wall of the top of the storage tank and the liquid surface of the liquid medium; The mechanical injection device has a liquid storage tank bottom connected to both the gas pumping device and the mechanical injection device. The gas pumping device is configured to pump protective gas into the bottom of the liquid storage tank. The protective gas generates bubbles in the liquid medium to pre-stir the liquid medium and increase the gas pressure in the pressurization zone. The increased gas pressure in the pressurization zone drives the liquid medium to be discharged to the mechanical injection device and prevents external impurity gases from entering the liquid storage tank.

[0006] By adopting the above scheme, the gas pumping device is connected to the bottom of the storage tank, allowing protective gas to be introduced from the bottom of the storage tank. When the protective gas is introduced, bubbles are generated inside the liquid medium. These bubbles rise to the pressurization zone, and the increased gas pressure in the pressurization zone applies pressure to the surface of the liquid medium, thereby pumping the liquid medium from the bottom of the storage tank into the mechanical injection device. Before the liquid medium is pumped out of the storage tank, i.e. before the gas pressure inside the pressurization zone increases, the rising bubbles in the liquid medium can agitate the liquid medium, ensuring that the composition of the liquid medium is uniform when it is pumped out of the storage tank. In addition, the high-pressure protective gas inside the pressurization zone fills the entire interior of the storage tank, preventing impurities such as oxygen from the outside of the storage tank from oxidizing the internal liquid medium, thus further achieving a sealing and protective effect.

[0007] In one embodiment of this application, the pneumatic injection device further includes: A filling cabinet, wherein the filling cabinet has multiple spaced placement chambers inside; A sealed chamber, wherein multiple sealed chambers are provided and are arranged one-to-one inside the placement cavity, and a pressure sensor is provided on the inner wall of the sealed chamber; The liquid storage tank is located inside the sealed chamber. A return air pipe is provided at the upper end of the liquid storage tank. One end of the return air pipe is connected to the liquid storage tank through an air valve, and the other end is connected to the air pumping device. An air inlet pipe and a liquid outlet pipe are respectively provided on both sides of the bottom end of the liquid storage tank. The two ends of the air inlet pipe are connected to the air pumping device and the liquid storage tank, respectively. The two ends of the liquid outlet pipe are connected to the mechanical injection device and the liquid storage tank, respectively.

[0008] By adopting the above scheme, a sealed chamber is set up outside the liquid storage tank. Without affecting the transportation of the liquid medium inside the liquid storage tank, if the airtightness of the liquid storage tank is insufficient, the protective gas inside the liquid storage tank can leak into the sealed chamber, thereby causing a change in the air pressure of the sealed chamber. At the same time, an air pressure sensor is set up on the inner wall of the sealed chamber. When the air pressure change reaches the action threshold of the air pressure sensor, the air pressure sensor responds and reminds the staff to carry out maintenance in time, so that the device can monitor the airtightness of the liquid storage tank.

[0009] In one embodiment of this application, the pumping device includes a support frame, inside which is a pump and a gas storage cylinder containing the protective gas. The input end of the pump is connected to the gas storage cylinder, the liquid storage tank is disposed on the support frame, the output end of the pump is connected to one end of the inlet pipe, and the other end of the return pipe is connected to the gas storage cylinder.

[0010] By adopting the above scheme, the protective gas inside the gas cylinder is pumped into the liquid storage tank using an air pump. The increased air pressure then pumps the liquid medium out of the liquid storage tank, making it not only convenient to add the liquid medium, but also ensuring that it is always protected by the protective gas throughout the entire filling process, preventing it from oxidizing and deteriorating.

[0011] In one embodiment of this application, the mechanical injection device includes: The robotic arm, of which multiple robotic arms are provided, each corresponding to one of the sealed chambers, has a fixed frame on its movable end, and a visual inspection camera is mounted on the fixed frame; An injection gun is mounted on the mounting frame and connected to the drain pipe. The robotic arm is configured to control the injection gun to inject liquid media into the car filler neck.

[0012] By adopting the above scheme, when different liquid media are injected into the car's filling port, the vision inspection camera on the robotic arm identifies the different filling ports on the car and controls the robotic arm to move the injection gun, so that the device can control multiple injection guns to inject different liquid media into the car respectively.

[0013] In one embodiment of this application, the injection gun is connected to the drain pipe, and the injection gun is provided with a cap opening assembly, which is configured to open the end cap of the car filler port.

[0014] By adopting the above solution and setting an opening component on the injection gun, the device can open the end cap on the car's filling port before filling the car, thereby improving the automation level of the device in the filling process.

[0015] In one embodiment of this application, the cover opening component includes: A fixed plate is connected and fixed to the fixed frame, and the injection gun passes through the fixed plate and is connected to the fixed frame through an elastic ring; A rotating disk is coaxially sleeved outside the fixed disk and rotatably connected to the fixed disk. A cover opener is provided outside the rotating disk, which is configured to clamp the end cover of the car filling port. A drive device is provided on the fixed frame, which controls the rotation of the rotating disk and cooperates with the robot arm to drive the cover opener to open the end cover of the car filling port.

[0016] In this embodiment, the elastic ring can be a rubber ring.

[0017] By adopting the above solution, when it is necessary to open the end cap of the car refueling port, the drive device can drive the cap opener so that the cap opener can open the end cap of the car refueling port. During this process, the refueling operation of the injection gun will not be affected.

[0018] In one embodiment of this application, the driving device includes a drive motor, which is mounted on the fixed frame. The drive shaft of the drive motor is coaxially connected to and fixed with a bevel gear. The upper end of the outer edge of the rotating disk is provided with a bevel tooth surface, and the bevel gear meshes with the bevel tooth surface.

[0019] By adopting the above solution, when facing the end cap of the car filler neck that needs to be rotated and twisted open, the drive motor can drive the bevel gear to rotate. By utilizing the transmission between the bevel gear and the bevel tooth surface, the rotating disk can be driven to rotate. The rotating disk can drive the cap opener to rotate, thereby unscrewing the end cap of the car filler neck.

[0020] In one embodiment of this application, the cap opener is a U-shaped component. The open end of the cap opener is rotatably connected to the rotating disk via a rotating shaft and is coaxial with the rotating disk. A coil spring is provided between the cap opener and the rotating disk at the rotating shaft. A strip cavity is provided on the side of the cap opener away from the open end. A movable magnetic strip is slidably connected inside the strip cavity along the length direction of the cap opener. Telescopic grooves are provided on both inner walls of the end of the cap opener near the strip cavity. A clamping block is slidably assembled inside the telescopic groove along the width direction of the cap opener. A transmission component is provided between the movable magnetic strip and the clamping block. When the movable magnetic strip is close to the electromagnet component, the two clamping blocks are driven to clamp the end cap of the car filler neck through the transmission component. An elastic element is provided between the clamping block and the inner wall of the telescopic groove. A rubber layer is provided on one side of both the clamping block and the movable magnetic strip.

[0021] In this embodiment, the elastic element can be a columnar spring.

[0022] By adopting the above scheme, when the cap opener needs to open the rotary end cap, the robot first moves the cap opener closer to the end cap. The side of the opener away from the opening end is squeezed by the end cap and deflects. As the robot moves closer, until the inner wall of the side of the opener away from the opening end abuts against the lower edge of the end cap, the electromagnet is energized and controls the robot to pull the opener back. The electromagnet assembly attracts the moving magnetic strip. As the moving magnetic strip approaches the electromagnet assembly, the transmission assembly drives the clamping strip to clamp the end cap, thereby enabling the drive motor to drive the opener to rotate and unscrew the end cap. When a cap opener is needed to open a snap-on end cap, after the cap opener clamps the end cap, the robotic arm can move the entire injection gun away from the car's filling port, thereby opening the snap-on end cap.

[0023] In one embodiment of this application, the transmission assembly includes: A transmission rack is slidably fitted inside the telescopic groove and located on the side of the clamping block near the moving magnetic strip. The end of the transmission rack near the moving magnetic strip is provided with an inclined mating surface, and the two ends of the moving magnetic strip are respectively provided with inclined driving surfaces. The inclined driving surfaces and the inclined mating surfaces are in contact with each other. A transmission gear is rotatably mounted inside the telescopic groove and located between the transmission rack and the clamping block. The clamping block has a toothed groove on the side near the movable magnetic strip, and the transmission gear meshes with the toothed groove and the transmission rack.

[0024] By adopting the above scheme, when the moving magnetic strip approaches the electromagnet assembly, the inclined driving surfaces on both sides of the moving magnetic strip can squeeze the inclined mating surfaces, thereby causing the two transmission racks to move away from each other. The transmission racks and transmission gears cooperate, thereby enabling the transmission gears to drive the clamping block to approach the end cover. The device clamps the end cover, thus completing the clamping work of the end cover.

[0025] The second objective of this invention is to provide a visual dispensing system for automotive liquid media.

[0026] The technical solution is as follows: A visual dispensing system for automotive liquid media includes a visual dispensing device for automotive liquid media, and further includes: A refueling channel, with a berthing area at one end; A gantry crane is positioned above the berthing area, a refueling cabinet is mounted on the gantry crane, and a robotic arm is mounted below the gantry crane and located on both sides of the berthing area.

[0027] By adopting the above solution, the refueling cabinet is placed above the gantry, and the robotic arms are mounted on both sides below the gantry, which allows cars to stop in the parking area, optimizes the spatial layout of the entire system, and saves floor space.

[0028] In summary, this application includes at least one of the following beneficial technical effects: by introducing protective gas into the bottom of the storage tank, the increased gas pressure inside the storage tank is used to extract the liquid medium from the tank. At the same time, the bubbles formed by the protective gas introduced at the bottom in the liquid medium can also pre-stir the liquid medium, preventing stratification. Furthermore, since the gas pressure inside the storage tank is greater than the gas pressure outside the tank, impurities such as oxygen from outside the tank will not enter the tank, thereby indirectly improving the sealing performance of the storage tank and achieving the purpose of pre-stirring and protecting the liquid medium inside the tank.

[0029] By setting up a sealed chamber outside the liquid storage tank and installing a pressure sensor inside the sealed chamber, the device can detect whether the liquid storage tank is well sealed by detecting changes in the pressure inside the sealed chamber, thus enabling the device to perform real-time sealing tests on the liquid storage tank under normal conditions.

[0030] By setting up a cap opener, the cap opener is used to clamp the end cap of the filling port. The cap opener is moved by the cooperation of the drive motor and the robot arm, so that the cap opener drives the end cap to rotate or pull the end cap to flip. Thus, the device can use a single cap opener to easily open the end caps of different filling ports of a car. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 1-9 This application provides a more detailed description of a visual dispensing device and system for automotive liquid media.

[0034] Example

[0035] Please see Figure 1 , Figure 2 and Figure 3 This application provides a visual filling device for automotive liquid media, comprising: a pneumatic filling device 1 and a mechanical injection device 2. The pneumatic filling device 1 includes a storage tank 11 for storing liquid media 3 and a pumping device 12 for pumping out protective gas. A pressurization area 111 is provided between the inner wall of the top of the storage tank 11 and the liquid surface of the liquid media 3. The bottom of the storage tank 11 is connected to the pumping device 12 and the mechanical injection device 2, respectively. The pumping device 12 is configured to pump protective gas into the bottom of the storage tank 11. The protective gas generates bubbles in the liquid medium 3 to pre-stir the liquid medium 3 and increase the gas pressure in the pressurization zone 111. The increased gas pressure in the pressurization zone 111 drives the liquid medium 3 to be discharged to the mechanical injection device 2 and prevents external impurity gas from entering the storage tank 11. By introducing the protective gas through the bottom of the storage tank 11, the bubbles generated inside the liquid medium 3 are used to stir the liquid medium 3. At the same time, the high-pressure protective gas fills the entire interior of the storage tank 11, ensuring a further sealing and protective effect.

[0036] In this embodiment, the protective gas can be nitrogen.

[0037] Please see Figure 2The pneumatic filling device 1 further includes a filling cabinet 13 and a sealing chamber 14. The filling cabinet 13 has multiple spaced placement chambers 131 inside. Multiple sealing chambers 14 are provided, each corresponding to one of the placement chambers 131. A pneumatic pressure sensor 141 is installed on the inner wall of each sealing chamber 14. A liquid storage tank 11 is located inside the sealing chamber 14. A return air pipe 112 is provided at the upper end of the liquid storage tank 11.

The bottom of the liquid storage tank 11 is provided with an air inlet pipe 113 and a liquid outlet pipe 114 on both sides. The two ends of the air inlet pipe 113 are connected to the air pumping device 12 and the liquid storage tank 11, respectively. The two ends of the liquid outlet pipe 114 are connected to the mechanical injection device 2 and the liquid storage tank 11, respectively. By setting a sealing chamber 14 outside the liquid storage tank 11 and using a pressure sensor 141 to detect the pressure change inside the sealing chamber 14, the airtightness of the liquid storage tank 11 can be monitored online.

[0038] In this embodiment, a filter assembly is also provided on the return gas pipe 112. The filter assembly can be a desiccant, which absorbs the moisture in the returned protective gas, so that the protective gas can be recycled repeatedly.

[0039] Please continue reading. Figure 2 The pumping device 12 includes a support frame 121, inside which is a pump and a gas cylinder storing the protective gas. The input end of the pump is connected to the gas cylinder. The liquid storage tank 11 is mounted on the support frame 121. The output end of the pump is connected to one end of the inlet pipe 113, and the other end of the return pipe 112 is connected to the gas cylinder. The pump pumps the protective gas inside the gas cylinder into the liquid storage tank 11, thereby using the increased air pressure to pump out the liquid medium 3 inside the liquid storage tank 11, while ensuring that the entire filling process is always protected by the protective gas, so that the liquid medium 3 will not oxidize or deteriorate.

[0040] Please see Figure 4 The mechanical injection device 2 includes a robotic arm 21 and an injection gun 22. Multiple robotic arms 21 are provided, each corresponding to a sealed chamber 14. A fixed frame 211 is provided on the movable end of the robotic arm 21, and a vision inspection camera 212 is mounted on the fixed frame 211. The injection gun 22 is mounted on the fixed frame 211 and connected to the drain pipe 114. The robotic arm 21 is configured to control the injection gun 22 to inject liquid medium 3 into the car's filler port. By using the vision inspection camera 212 to identify different filler ports on the car, the device can operate multiple injection guns 22 to inject different liquid media 3 into the car, improving the efficiency and convenience of the injection process.

[0041] Please continue reading. Figure 4 The injection gun 22 is connected to the drain pipe 114. The injection gun 22 is provided with a cap opening assembly 23, which is configured to open the end cap 6 of the car refueling port. By setting the cap opening assembly 23 on the injection gun 22, different types of end caps 6 on the car refueling port can be opened, thereby improving the automation level of the device in the refueling operation.

[0042] Please see Figure 5 The cap opening assembly 23 includes a fixed plate 231 and a rotating plate 232. The fixed plate 231 is connected and fixed to the fixed frame 211. The injection gun 22 passes through the fixed plate 231 and is connected to the fixed frame 213 through an elastic ring 213. The rotating plate 232 is coaxially sleeved outside the fixed plate 231 and is rotatably connected to the fixed plate 231. A cap opener 233 is provided outside the rotating plate 232. The cap opener 233 is configured to clamp the end cap 6 of the car filling port. A driving device 234 is provided on the fixed frame 211. The driving device 234 controls the rotating plate 232 to rotate and cooperates with the robotic arm 21 to drive the cap opener 233 to open the end cap 6 of the car filling port. When it is necessary to open the end cap 6 of the car filling port, the driving device 234 can drive the cap opener 233 so that the cap opener 233 can open the end cap 6 of the car filling port. During this process, the injection gun 22's injection operation will not be affected.

[0043] Please continue reading. Figure 5 The driving device 234 includes a drive motor 2341, which is mounted on the fixed frame 211. The drive shaft of the drive motor 2341 is coaxially connected to a bevel gear 2342. The upper edge of the rotating disk 232 is provided with a bevel tooth surface 2321. The bevel gear 2342 meshes with the bevel tooth surface 2321. When facing the end cap 6 of the car filler neck that needs to be rotated and twisted open, the drive motor 2341 can drive the cap opener 233 to rotate. When facing the snap-on end cap 6, it can also drive the cap opener 233 to adjust the angle so that it can be snapped onto the end cap 6.

[0044] Please see Figure 6The lid opener 233 is a U-shaped component. The open end of the lid opener 233 is rotatably connected to the rotating disk 232 via a rotating shaft and is coaxial with the rotating disk 232. A coil spring is provided between the lid opener 233 and the rotating disk 232 at the rotating shaft. A strip cavity 2331 is provided on the side of the lid opener 233 away from the open end. An electromagnet assembly 2332 is provided on the inner wall of the bottom end of the strip cavity 2331. A movable magnetic strip 2333 is slidably connected inside the strip cavity 2331 along the length direction of the lid opener 2333. Telescopic grooves 2334 are provided on both inner walls of the end of the lid opener 2333 near the strip cavity 2331. Clamping devices are slidably fitted inside the telescopic grooves 2334 along the width direction of the lid opener 2333. Block 2330, a transmission component is provided between the movable magnetic strip 2333 and the clamping block 2330. When the movable magnetic strip 2333 approaches the electromagnet component 2332, the transmission component drives the two clamping blocks 2330 to clamp the end cap 6 of the car filler neck. An elastic element 2335 is provided between the clamping block 2330 and the inner wall of the telescopic groove 2334. A rubber layer is provided on one side of both the clamping block 2330 and the movable magnetic strip 2333. By setting a U-shaped cap opener 233 and setting movable magnetic strip 2333 and electromagnet component 2332 that can cooperate with each other, the cap opener 233 can clamp various types of end caps 6, thereby facilitating the subsequent opening of the end cap 6 and improving the automation of the device.

[0045] Please continue reading. Figure 6 The transmission assembly includes a transmission rack 2336 and a transmission gear 2339. The transmission rack 2336 is slidably mounted inside the telescopic groove 2334 and is located on the side of the clamping block 2330 near the movable magnetic strip 2333. The end of the transmission rack 2336 near the movable magnetic strip 2333 has an inclined mating surface 2337. The two ends of the movable magnetic strip 2333 each have inclined driving surfaces 2338. The inclined driving surfaces 2338 and the inclined mating surfaces 2337 are in close contact with each other. The transmission gear 2339 is rotatably mounted inside the telescopic groove 2334 and is located between the transmission rack 2336 and the clamping block 2330. The clamping block 2330 has a toothed groove on the side near the moving magnetic strip 2333. The transmission gear 2339 meshes with the toothed groove and the transmission rack 2336. By setting the transmission gear 2339, when the moving magnetic strip 2333 is close to the electromagnet assembly 2332, the clamping strip can protrude from the cover opener 233, thereby achieving clamping of the end cover 6 in three directions.

[0046] The second objective of this invention is to provide a visual dispensing system for automotive liquid media.

[0047] Please see Figure 1The technical solution is as follows: A visual refueling system for automotive liquid media includes a visual refueling device for automotive liquid media, and further includes: a refueling channel 4 and a gantry 5. One end of the refueling channel 4 is provided with a parking area 41. The gantry 5 is set above the parking area 41. The refueling cabinet 13 is mounted on the gantry 5. The robotic arm 21 is mounted below the gantry 5 and located on both sides of the parking area 41. Through the refueling cabinet 13 and robotic arm 21 set up above and below, the car can stop in the parking area 41, thus optimizing the spatial layout of the entire system and saving floor space.

[0048] In summary, when it is necessary to fill the car with liquid medium 3, the vision inspection camera 212 identifies the filling port on the car located in the parking area 41, thereby controlling the corresponding robotic arm 21 to fill the car. During the filling process, the air pump pumps the protective gas from the gas storage tank into the bottom of the liquid storage tank 11. The protective gas forms rising bubbles in the liquid medium 3, thereby agitating the liquid medium 3 and making it more uniform before being pumped out of the liquid storage tank 11. At the same time, the air pressure in the pressurization area 111 above the liquid surface of the liquid medium 3 continuously increases, thereby pumping the liquid medium 3 out of the liquid storage tank 11, through the drain pipe 114 to the injection gun 22. At this time, the injection gun 22 is controlled to approach the end cap 6 of the filling port. During the approach, the cap opener 233 is automatically deflected by the pressure of the end cap 6. As the injection gun 22 continues to approach, under the action of the internal coil spring, the cap opener 233 is deflected. When the end cap 6 is fastened to the lower edge, the cap opener 233 is pulled back and the electromagnet assembly 2332 is energized, which causes the magnetic strip 2333 to move closer to the electromagnet assembly 2332. Under the resistance and sliding of the inclined driving surface 2338 and the inclined mating surface 2337, the clamping block 2330 clamps the two sides of the end cap 6, thereby achieving clamping of the end cap 6 from three sides. The drive motor 2341 drives the cap opener 233 to rotate, thereby enabling the rotating end cap 6 to be unscrewed. When facing the snap-on end cap 6, the robot arm 21 drives the injection gun 22 away from the end cap 6, which can open the end cap 6, thereby realizing the filling work of the car filling port.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
