[0003] Currently, industrial IoT gas meters typically use automated assembly lines to transport tooling, allowing the tooling used to install gas meter components to be sequentially transferred to various assembly lines, achieving the goal of automated gas meter assembly. However, when the tooling on the existing assembly line moves to the component installation area and the component is installed onto the tooling, the tooling is prone to displacement, which can lead to improper assembly of the component onto the tooling, affecting subsequent processing. Furthermore, the existing assembly line cannot detect whether the tooling is misaligned, which can also prevent the component from being installed onto the tooling smoothly. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0043] Example

[0044] like Figures 1 to 8 As shown, the present invention includes a support frame 1, on which a transmission unit for transmitting a tooling 4 is provided. The support frame 1 also includes a pressing unit and an lifting unit for fixing the tooling 4 to the transmission unit. The lifting unit includes an lifting cylinder 7 and a support plate 8. The lifting cylinder 7 is fixed to the bottom of the transmission unit. The support plate 8 is connected to the output shaft 14 of the lifting cylinder 7. The top of the support plate 8 is provided with a rotating unit and several telescopic units. The rotating unit includes a first airbag 10. The support plate 8 has a cavity inside which is connected to the first airbag 10 through a conduit. The lifting cylinder 7 can deliver pressurized gas into the cavity. When the telescopic unit retracts into the support plate 8, the telescopic unit can block the conduit.

[0045] In existing technologies for automated manufacturing of gas meters using the Industrial Internet of Things (IIoT), tooling is typically used as a positioning tool for components. The assembly line can automatically transport tooling 4, enabling smooth assembly on subsequent assembly lines. However, existing assembly lines often fail to provide adequate positioning for gas meter components during installation, leading to inaccurate installation and impacting subsequent assembly processes. To address this, this technical solution incorporates an upper lifting unit and a lowering unit on the transmission unit. When the transmission unit transports tooling 4, containing the gas meter components, to a preset position, the upper lifting unit simultaneously presses down and lifts the top of tooling 4. This combination secures tooling 4 to the transmission unit, achieving temporary fixation and preventing displacement during gas meter component installation, thus improving assembly accuracy.

[0046] To prevent the tooling 4 from tilting during transmission, this technical solution, while using an upper lifting unit and a lower pressing unit to fix the tilted tooling 4, addresses the issue of gas meter components not being properly installed on it. Instead, this solution includes several telescopic units on the support plate 8 of the upper lifting unit. These telescopic units can extend and retract vertically on the support plate 8, with their distribution area matching the bottom area of ​​the tooling 4. This allows the tooling 4 to move directly above the support plate 8. First, the lower pressing unit presses the top of the tooling 4 firmly, then the output shaft 14 of the upper lifting cylinder 7 drives the support plate 8 upwards. When the tooling 4 is not tilted, its bottom surface compresses the telescopic units at the top of the support plate 8 into the support plate 8. Figure 9As shown, the conduit is currently blocked, and the first airbag 10 will not inflate. However, when the tooling 4 is tilted, during the upward movement of the support plate 8, some of the telescopic units on the support plate 8 fail to contact the bottom of the tooling 4. Figure 10 As shown, the telescopic unit in this part does not retract into the cavity of the support plate 8, thus causing the conduit to be in communication with the first airbag 10. Therefore, the air pressure entering the cavity from the upper cylinder 7 will enter the first airbag 10 through the conduit, forcing the first airbag 10 to gradually expand. Since the bottom of the tooling 4 in this technical solution is provided with an arc groove, when the support plate 8 supports the bottom of the tooling 4, the first airbag 10 is exactly in the arc groove of the tooling 4. Therefore, the first airbag 10 will expand towards the inner wall of the arc groove. The expanded first airbag 10 can provide internal support for the tooling 4. The rotating unit drives the first airbag 10 to rotate on the horizontal plane. During the rotation, the first airbag 10 restores the tooling 4 from the tilted state to the upright state, thereby ensuring that the parts can be smoothly installed with the tooling.

[0047] The transmission unit includes a truss 2, a transmission chain 9, and several transmission teeth. The truss 2 is fixed on the support frame 1, the transmission teeth are rotatably mounted on the truss 2, and the transmission chain 9 is connected to the transmission teeth.

[0048] In this embodiment, a servo motor is also provided on the truss 2. The servo motor is connected to a reducer. The reducer is connected to one of the transmission teeth and drives the transmission teeth to rotate, thereby driving the conveyor chain 9 on the truss 2 to rotate and transfer the tooling placed on the conveyor chain 9 to the preset position.

[0049] The pressing unit includes a pressing cylinder 6, a horizontal plate 3, and a pressing rod 5. The pressing cylinder 6 is fixed on the truss 2, and the output end of the pressing cylinder 6 is connected to the horizontal plate 3. The pressing rod 5 is fixed to the bottom of the horizontal plate 3.

[0050] When fixing the upper end of the tooling 4, the horizontal plate 3 is driven to move downward by the downward pressure cylinder 6. As the horizontal plate 3 moves downward, it drives the downward pressure rod 5 to move along with it, thereby applying downward pressure to the top of the tooling 4.

[0051] The top of the support plate 8 is provided with several blind mounting holes;

[0052] The telescopic unit includes a support rod 33, a first telescopic tube 27, a sealing rod 29, and a first elastic element 28. The two ends of the first telescopic tube 27 are connected to the support rod 33 and the sealing rod 29, respectively. The support rod 33 and the first telescopic tube 27 are located in the installation blind hole, and the sealing rod 29 is inserted into the cavity. The first elastic element 28 is sleeved on the sealing rod 29 and is located in the installation blind hole.

[0053] In this embodiment, the telescopic unit is used to determine whether the tooling 4 above the support plate 8 is tilted. When the upper cylinder 7 drives the support plate 8 to move upward, the top of the support rod 33 is pressed down by the top surface of the tooling 4. During the downward pressing process, the support rod 33 drives the first telescopic tube 27 and the sealing rod 29 to move downward together and compresses the first elastic element 28 located in the installation blind hole. After the assembly is completed and the tooling 4 is transferred away, the telescopic unit extends out of the installation blind hole of the support plate 8 again under the action of the first elastic element to continue to detect the tilt of the next tooling 4.

[0054] The cavity includes an upper cavity 21 and a lower cavity 20. The upper cavity 21 and the lower cavity 20 are connected by vertical tubes, the same number of which are the same as the number of sealing rods 29. The inner diameter of the vertical tubes is the same as the outer diameter of the sealing rods 29. The lower end of the sealing rod 29 is located in the upper cavity 21, and the sealing rod 29 can be moved into the vertical tube to seal the sealing rod 29. The conduit is connected to the upper cavity 21.

[0055] In this embodiment, to ensure that the conduit communicating with the first airbag 10 is temporarily blocked after the telescopic unit retracts into the blind mounting hole, thus preventing the pressurized gas delivered to the cavity by the upper cylinder 7 from being transmitted to the first airbag 10 through the conduit and preventing the first airbag 10 from inflating, an upper cavity 21 and a lower cavity 20 are provided in the support plate 8. The upper cavity 21 and the lower cavity 20 are connected by several vertical pipes. Therefore, when the fixture 4 is not tilted, when the support plate 8 contacts the bottom of the fixture 4, the bottom of the fixture 4 can press the entire telescopic unit into the blind mounting hole. During the process of the telescopic unit retracting into the blind mounting hole, the sealing rod 29 at the lower end moves from the upper cavity 21. When the device moves into the vertical pipe, the sealing rod 29 is used to temporarily seal the vertical pipe. At this time, the pressurized gas transmitted from the upper cylinder 7 to the lower cavity 20 cannot enter the upper cavity 21 through the vertical pipe, and the first airbag 10 will not inflate. However, when the tooling 4 is tilted, causing at least one of the telescopic units to fail to retract into the installation blind hole, the telescopic unit that fails to retract into the installation blind hole does not seal the lower vertical pipe. At this time, the gas entering the lower cavity 20 will enter the upper cavity through the vertical pipe, and then enter the first airbag 10 through the conduit, causing the first airbag 10 to inflate and provide internal support for the arc-shaped groove of the tooling 4. This allows the rotating unit to rotate the tooling 4 in the internally supported state to restore it to its normal position.

[0056] The telescopic unit also includes a movable rod 24. The end of the sealing rod 29 facing the first telescopic tube 27 is provided with a connecting blind hole. A second elastic element 35 is provided in the connecting blind hole. The movable rod 24 extends from the top of the support rod 33 through the first telescopic tube 27 and into the connecting blind hole. The movable rod 24 is connected to the second elastic element 35. The bottom of the movable rod 24 is also provided with an air guide tube 30. The air guide tube 30 is connected to the bottom of the sealing rod 29.

[0057] The movable rod 24 is provided with an air chamber 34. The side wall of the movable rod 24 is provided with an air inlet 31 and an air outlet. The air outlet is a stepped hole. The air outlet is also provided with a limiting member for fixing the movable rod 24 to the support rod 33.

[0058] When the tooling 4 is adjusted to be aligned by the rotating unit, some of the telescopic units on the support plate 8 protrude to the top of the support plate 8. In order to prevent the protruding telescopic units from blocking the side wall of the tooling 4 during the rotation and reset process, thus preventing the tooling 4 from being properly aligned, a first telescopic tube 27 is provided in the central part of the telescopic unit. The first telescopic tube 27 is a corrugated tube with closed structures at both ends. In the initial state, it is filled with pressurized gas that expands and stretches. When the tooling 4 is rotated to be aligned by the rotating unit, the gas introduced into the first telescopic tube 27 is discharged, causing the first telescopic tube 27 to retract and change its length. This causes the support rod 33 located at the top of the first telescopic tube 27 to move downward, and finally retracts the top of the support rod 33 into the blind hole, thus preventing the support rod 33 from blocking the tooling 4 during the rotation process.

[0059] In this embodiment, a movable rod 24 is provided to discharge the gas inside the first telescopic tube 27. An air inlet 31 and an air outlet are respectively provided on the side wall of the movable rod 24. The air inlet 31 is near the lower end of the movable rod 24, and the air outlet is near the upper end of the movable rod 24. Initially, to ensure a sealed state inside the first telescopic tube 27, the movable rod 24 is fixed inside the support rod 33 by the limiting member. At this time, the air inlet 31 is not connected to the first telescopic tube 27. However, when the limiting member is removed, the movable rod 24... After being limited, under the action of the second elastic element 35, the movable rod 24 is pushed to move upward, so that the air inlet 31 on the side wall of the movable rod 24 moves into the first telescopic tube 27, connecting the first telescopic tube 27. At this time, the gas inside the first telescopic tube 27 enters into the air chamber 34 through the air inlet 31, and then flows out through the air outlet, thereby realizing the discharge of the gas inside the first telescopic tube 27, which in turn allows the first telescopic tube 27 to retract, shortening the length of the first telescopic tube 27, and finally causing the support rod 33 to retract into the installation blind hole.

[0060] The support rod 33 has an annular groove on its side wall, and a second airbag 25 is provided in the annular groove. The second airbag 25 is connected to the air chamber 34 through a hose 41. The support rod 33 also has a limiting hole 36, and the second airbag 25 is connected to the limiting hole 36 through a connecting pipe. The limiting member includes a third elastic member 40 and a limiting ball 37. The third elastic member 40 is used to push the limiting ball 37 into the limiting hole 36.

[0061] In this embodiment, to achieve automatic unlocking of the limiting component, a second airbag 25 with an annular structure is provided on the outer circumferential wall of the support rod 33. Initially, when the limiting component on the movable rod 24 limits its movement, the upper cylinder 7 delivers pressurized gas into the lower cavity 20. The pressurized gas enters the upper cavity 21 through a vertical pipe, and a portion of the gas then enters the air chamber 34 of the movable rod 24 through the air guide pipe 30 at the bottom of the movable rod 24. The gas entering the air chamber 34 then enters the second airbag 25 through a hose 41, causing the support rod 33 to expand to its maximum deformation in the circumferential direction. The expanded second airbag 25 is positioned above the support plate 8. When the rotating unit moves the workpiece 4 in an inclined state... During rotation, the tooling 4, in the process of rotation, its sidewalls squeeze the second airbag 25 on the sidewall of the support rod 33 protruding above the support plate 8. The gas inside the squeezed second airbag 25 enters the limiting hole 36 through the connecting pipe, pushing the limiting ball 37 in the limiting hole 36 back towards the air outlet, and finally retracting the limiting ball 37 into the air outlet, thereby removing the constraint of the limiting ball 37 on the movable rod 24. At this time, the movable rod 24 moves upward under the action of the second elastic element 35, and finally causes the air inlet 31 on the movable rod 24 to move into the first telescopic tube 27, while the air outlet on the movable rod 24 moves to communicate with the outside, finally achieving the purpose of venting the gas in the first telescopic tube 27.

[0062] The top of the movable rod 24 has a spherical structure.

[0063] The first telescopic tube 27 is also provided with a fourth elastic element 23. The fourth elastic element 23 is distributed along the axial direction of the first telescopic tube 27, and its two ends are connected to the two internal ends of the first telescopic tube 27. When the first telescopic tube 27 is in an expanded and stretched state, the fourth elastic element 23 is in a stretched state. Therefore, by using the fourth elastic element 23, the first telescopic tube 27 can quickly retract when it is connected to the air inlet 31.

[0064] The upper cylinder 7 includes a cylinder body 16, a piston 18, and a second telescopic tube 17. The cylinder body 16 is fixed to the bottom of the truss 2. The piston 18 is located inside the cylinder body 16. The output shaft 14 extends into the cylinder body 16 and is connected to the piston 18. The second telescopic tube 17 is located inside the cylinder body 16. One end of the second telescopic tube 17 is connected to the inner bottom of the cylinder body 16, and the other end is connected to the piston 18. The output shaft 14 has a channel. One end of the channel passes through the piston 18 and communicates with the second telescopic tube 17. The other end extends into the support plate 8 and communicates with the lower cavity 20.

[0065] In this embodiment, in order to utilize the upper cylinder 7 to supply gas to the lower cavity 20, thereby achieving the purpose of sharing a gas source with the cylinder, a second telescopic pipe 17 is also provided inside the cylinder body 16. The second telescopic pipe 17 is a bellows with closed ends. When an external gas source supplies pressurized gas into the cylinder body 16, the pressurized gas causes the piston 18 to move inside the cylinder body 16, thereby driving the output shaft 14 to move the support plate 8 upward. While supplying pressurized gas into the cylinder body 16, pressurized gas is simultaneously supplied into the second telescopic pipe 17. The pressurized gas enters the lower cavity 20 through the channel, thereby achieving the purpose of supplying pressurized gas into the cavity of the support plate 8.

[0066] In this embodiment, the second telescopic tube 17 can be used to deliver pressurized gas into the cavity of the support plate 8. On the other hand, the expanded second telescopic tube 17 can limit and buffer the piston 18 to a certain extent, thereby improving the stability of the upper cylinder 7.

[0067] The upper cylinder 7 also includes a third telescopic tube 15, which is sleeved on the output shaft 14. One end of the third telescopic tube 15 is connected to the piston 18, and the other end is connected to the inner top of the cylinder body 16. The channel of the output shaft 14 is also provided with an air supply pipe 32, one end of which is connected to the third telescopic tube 15, and the other end is connected to the first telescopic tube 27.

[0068] In this embodiment, in order to enable the delivery of pressurized gas into the first telescopic tube 27 and cause it to expand, a third telescopic tube 15 is also provided in the cylinder 16. The gas supply pipe 32 is connected to the first telescopic tube 27, so that when the external gas source delivers pressurized gas into the third telescopic tube 15, the pressurized gas enters the first telescopic tube 27 through the gas supply pipe 32 and can expand smoothly.

[0069] Furthermore, the top of the support plate 8 is provided with a groove, the rotating unit includes a motor 13, the motor 13 is installed in the groove, the output end 12 of the motor 13 is provided with a fixing block 11, and the first airbag 10 is fixed on the side wall of the fixing block 11.

[0070] In this embodiment, during the process of the support plate 8 lifting the tooling 4, the fixing block 11 on the output end 12 of the motor 13 is located in the arc-shaped groove of the tooling 4, so that the first airbag 10 can act on the inner wall of the arc-shaped groove during the expansion process, thereby achieving the purpose of supporting the tooling 4, and thus enabling the motor 13 to drive the tooling 4 to rotate when working.

[0071] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
