Description

Technical Field

[0001] This application relates to the field of automated assembly technology for ultrasonic gas meters, and in particular to a fully automated ultrasonic gas meter assembly platform. Background Technology

[0002] Ultrasonic gas meters, as high-precision gas measuring devices, are widely used in household natural gas measurement. Currently, the production of ultrasonic gas meters mainly relies on semi-automatic or automatic production lines, which significantly improves production efficiency and correspondingly enhances product quality and consistency.

[0003] Currently, automated production lines utilize simple conveyor belts and robotic arms to automate processes. While these methods can improve production efficiency to some extent, they still have many shortcomings.

[0004] However, existing automated production equipment typically performs one assembly step for each type of device before moving to the next station for assembly. While this achieves full automation, the repeated repositioning of the ultrasonic gas meter leads to low production efficiency. Furthermore, the frequent replacement of positioning and fixing devices causes slight deviations in the ultrasonic gas meter during transmission, which are amplified in subsequent processes, affecting production stability and product quality. Therefore, designing a fully automated, efficient, and stable ultrasonic gas meter assembly platform that allows for complete assembly of the ultrasonic gas meter in a single positioning and clamping operation is a pressing technical problem that needs to be solved.

[0036] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model. The inventors of this application have found that existing ultrasonic gas meter assembly methods have problems such as cumbersome manual operation and low production efficiency. Therefore, this application mainly adopts the following fully automatic ultrasonic gas meter assembly platform, including a base, multiple workstations set on the base, and a parts assembly device for assembling ultrasonic gas meters at each workstation. The assembly device includes multiple assembly robots set above each workstation, each assembly robot having a tool head for performing different assembly processes, and a conveying device set along the arrangement direction of the workstations for transferring ultrasonic gas meters between workstations. This achieves fully automated assembly of ultrasonic gas meters, improving production efficiency and product quality. The following is a further detailed description of this application. Example

[0037] The fully automated ultrasonic gas meter assembly platform provided in this application includes a base 1 and multiple workstations set on the base. Each workstation is equipped with a parts assembly device for assembling ultrasonic gas meters. The assembly device includes multiple assembly robots 2 set above each workstation. Each assembly robot 2 has a tool head for performing different assembly processes. For example, one assembly robot can be equipped with a screw-tightening tool head for tightening screws on the ultrasonic gas meter; another assembly robot can be equipped with a gripping tool head for gripping parts. The tool heads of these assembly robots can be replaced according to actual process requirements to achieve automation of multiple assembly processes. A conveyor device 3 arranged along the workstation arrangement direction is used to transfer the ultrasonic gas meters between the workstations. The conveyor device 3 includes a conveyor belt 31, a power motor 32, and a support platform 33 for placing the ultrasonic gas meters. Through this design, the fully automated assembly of ultrasonic gas meters is achieved, improving production efficiency and product quality.

[0038] The base 1 serves as the foundation of the entire assembly platform, with multiple workstations on it. Each workstation is equipped with a parts assembly device for assembling ultrasonic gas meters. The first workstation is the front shell loading station. The gripping mechanism on the assembly robot's working arm picks up the upper front shell of the ultrasonic gas meter from the loading station and places it on a carrier platform 33 of the conveyor device 3. The front shell on the carrier platform 33 is transported to the next workstation by a conveyor belt. The second workstation places the display screen protection sheet. The vacuum suction cup installed on the assembly robot's working arm picks up the display screen protection sheet from the material box and places it in the corresponding position. It is then transported to the next workstation by a conveyor belt. The third workstation is used to assemble the ultrasonic gas meter inner core assembly. The assembly robot's working arm at the third workstation is equipped with a clamping device that takes the inner core assembly out of the material box, places it inside the front shell, and presses it to engage with the claws of the front shell to complete the installation. The ultrasonic meter is conveyed to the next station for back cover installation via conveyor belt. At the fourth station, a robotic arm installs a clamp, places the back cover in its corresponding position, and presses the front and rear cover clips to secure it. The clamps then lift, and the meter is conveyed to the next station for screw tightening. At the fifth station, a robotic arm with an electric screwdriver presses the screws into the screw holes on the back cover and tightens them. After installing all four screws, the conveyor belt takes the meter to the sixth station, where the assembly robot's gripping mechanism picks up the ultrasonic meter and places it in a storage box, completing the assembly process. These stations can be flexibly adjusted to accommodate the assembly requirements of different models and specifications of ultrasonic meters.

[0039] The conveying device 3 includes a conveyor belt 31, a power motor 32, and a support platform 33 for placing the ultrasonic gas meter. The power motor is a high-performance servo motor to ensure smooth and accurate operation of the conveyor belt. The support platform 33 is used to place the ultrasonic gas meter, and to improve the accuracy and stability of the conveying device, a limiting device is installed on the support platform. The limiting device includes multiple limiting posts 331 for precise positioning of the ultrasonic gas meter. Scale lines can also be set on the limiting posts 331 to allow operators to quickly adjust the position.

[0040] To further enhance the stability of the ultrasonic gas meter during transport, a fixing device is also installed on the support platform 33. The fixing device includes a pneumatic suction cup 332 and a vacuum pump 333; the vacuum pump 333 provides suction negative pressure to the pneumatic suction cup 332 via a pipe. The pneumatic suction cup 332 can hold the ultrasonic gas meter in place using air pressure, ensuring it does not move during transport. The vacuum pump 333 provides sufficient negative pressure to firmly hold the ultrasonic gas meter in place, effectively preventing the ultrasonic gas meter from shaking during transport. Multiple auxiliary positioners 334 are installed on the support platform to cooperate with the sensors on the working arm of the assembly machine 2 for accurate positioning of the workpiece on the support platform 33.

[0041] To achieve precise control of the assembly robot, the conveyor device 3 is also equipped with a position sensor 34. The position sensor 34 verifies the position of the workpiece on the conveyor belt, ensuring that the assembly robot 2 can accurately locate the target workpiece. The position sensor 34 can be a photoelectric sensor or a magnetic sensor, offering high sensitivity and reliability. Based on the feedback information from the position sensor, the assembly robot 2 can adjust its movements in a timely manner, ensuring the smooth progress of the assembly process and the positioning of the ultrasonic gas gauge.

[0042] The conveying device 3 is also equipped with a power transmission device 35 for transmitting power to the equipment on the support platform. Specifically, the power transmission device 35 includes a power transmission frame 351 mounted on the conveyor belt worktable, a power receiving block 352 sliding on the power transmission frame, and a connecting rod 353 connecting to the support platform. The power receiving block 352 can slide along the power transmission frame 351 to ensure that the support platform always receives a stable power supply during the conveying process. The connecting rod 353 is used to connect the power receiving block 352 to the support platform 33, and moves the power receiving block 352 as the support platform 33 moves.

[0043] The grounding block 352 includes a pulley 3521, a grounding plate 3522, and a connecting wire. The pulley 3521 can move within a groove on the power transmission frame 351. The grounding plate 3522 is responsible for contacting the electrode strips installed within the groove of the power transmission frame to achieve power transmission. The connecting wire is used to connect the grounding plate 3522 to the equipment on the support platform 33 to ensure a normal power supply. The grounding plate can be made of multi-layer composite material, possessing good conductivity and wear resistance. The connecting wire can be a shielded cable to prevent electromagnetic interference.

[0044] To further improve the reliability and stability of the power transmission unit 35, the contact plate 3522 is also equipped with an elastic clamping device, including a spring 3523 and a guide post 3524. The spring 3523 provides constant pressure, firmly pressing the contact plate 3522 against the electrode strip of the transmission frame to ensure good electrical contact. The guide post guides the spring, ensuring it remains on the correct path. The design of the elastic clamping device allows the contact plate 3522 to maintain good contact performance even after prolonged use, thus guaranteeing the long-term stable operation of the power transmission unit 35.

[0045] The implementation principle of this embodiment is as follows:

[0046] Through the coordinated operation of the base, multiple workstations, assembly robots, conveying devices, and various auxiliary devices, the entire assembly process of ultrasonic gas meters is automated. The base provides a stable foundation, ensuring the stability and safety of the entire platform. The combined use of multiple workstations and assembly robots allows different assembly processes to be performed simultaneously, significantly improving production efficiency. Precise control of the conveying device and the effective coordination of various auxiliary devices ensure the stability and accuracy of the ultrasonic gas meters during transport. The power transmission device provides power to the equipment on the platform, further enhancing the automation and flexibility of the assembly platform. The precise design and reliable performance of the power transmission device ensure continuous power supply to the ultrasonic gas meters during transport, enabling the equipment on the platform to operate normally and facilitating more complex assembly processes.

[0047] 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.
