[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0023] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example: Figures 1 to 5 As shown, an automated assembly device for ultrasonic gas meter sealing rings mainly consists of a loading mechanism 2 for loading sealing rings 1, a gripping mechanism 3 for gripping sealing rings 1, and a transmission mechanism 4 for transmitting gas meter components. To achieve automated assembly of sealing rings 1 without manual operation, the loading mechanism 2 in this embodiment mainly comprises a material rack 2-1, a push plate 2-2, a longitudinal drive component 2-3 capable of driving the push plate 2-2 to push the sealing rings 1 up and down along the height of the material rack 2-1, an indexing plate 2-4, and a circumferential drive mechanism for driving the indexing plate 2-4 to rotate circumferentially. The device consists of drive elements 2-5. The longitudinal drive assembly 2-3 pushes the push plate 2-2 to move the sealing ring 1 to the required position. Then, the gripping mechanism 3 grips the sealing ring 1 and installs it onto the tray fixture 4-1 on the transmission mechanism 4, thus achieving automatic assembly with the gas meter components. The entire process does not require manual intervention, which not only improves the production efficiency and assembly quality of ultrasonic gas meters, but also reduces labor costs and safety risks, enhances the user experience, and is conducive to the promotion and use of the ultrasonic gas meter sealing ring automated assembly device in the market.

[0026] Specifically, in order to maximize the number of sealing rings 1 on the material rack 2-1 without affecting the gripping mechanism 3's gripping of the sealing rings 1, i.e. reducing the gripping difficulty while ensuring the assembly speed, the material rack 2-1 in this embodiment is composed of multiple optical shafts 2-1-1. The sealing rings 1 in this embodiment can be cuboid structures, and the number of optical shafts 2-1-1 can be eight. Four of the optical shafts 2-1-1 form a horizontal arrangement for mounting the sealing rings 1, and the other four optical shafts 2-1-1 form a vertical arrangement for mounting the sealing rings 1. By arranging the eight optical shafts 2-1-1, multiple sealing rings 1 can be stacked vertically along the optical shafts 2-1-1, and adjacent sealing rings 1 can be staggered in the horizontal and vertical directions, or vertically arranged between adjacent sealing rings 1. This avoids the upper and lower sealing rings 1 from sticking together due to their identical structure, thereby ensuring the gripping effect and efficiency of the gripping mechanism 3.

[0027] In this embodiment, to further improve the assembly speed of the assembly device, multiple material racks 2-1 are used. Multiple material racks 2-1 can accommodate as many sealing rings 1 as possible, reducing the impact of loading and unloading on the assembly speed. To avoid interference between adjacent material racks 2-1 and to ensure the stability of the indexing plate 2-4 during rotation, avoiding uneven force distribution, multiple material racks 2-1 are respectively installed on the indexing plate 2-4 and equidistantly arranged along the circumference of the indexing plate 2-4.

[0028] Specifically, the longitudinal drive assembly 2-3 in this embodiment includes a longitudinal drive member, a longitudinal drive slide rail, and a longitudinal drive plate 2-6 that can slide along the longitudinal slide rail. The longitudinal drive member can be a highly stable drive cylinder. The drive cylinder pushes the longitudinal drive plate 2-6, which in turn pushes the push plate 2-2, and causes the sealing ring 1 located above the push plate 2-2 to slide upward along the height direction of the material rack 2-1 until it moves to the desired position. Then, the gripping mechanism 3 grips the sealing ring 1.

[0029] To ensure optimal performance, the size of the longitudinal drive plate 2-6 is matched to the size of the push plate 2-2. The indexing plate 2-4 has a through slot 2-7 for the longitudinal drive plate 2-6 to pass through. The longitudinal drive plate 2-6 moves upward through the through slot 2-7 until it pushes the push plate 2-2. Furthermore, the longitudinal drive assembly 2-3 also includes a sensing element 2-8 capable of detecting that the push plate 2-2 is located above the longitudinal drive plate 2-6. The sensing element 2-8 can be installed on top of the longitudinal drive slide rail. When the sealing ring 1 is detected to enter the area that the sensing element 2-8 can detect, the sensing element 2-8 transmits a signal indicating that the sealing ring 1 is in place to the gripping mechanism 3, which then drives the gripping mechanism 3 to grasp the sealing ring 1 located within that area. The sensing element 2-8 is a photoelectric sensor. By collecting data through the photoelectric sensor and combining it with software algorithms, intelligent control and automated operation of the assembly device can be achieved.

[0030] For enhanced stability, a pallet base plate 2-9 is installed at the bottom of the material rack 2-1. The pallet base plate 2-9 has an opening, the size of which is adapted to the size of the longitudinal drive plate 2-6. A base 2-10 is installed below the indexing plate 2-4, and the indexing plate 2-4 is rotatably mounted on the base 2-10. The circumferential drive element 2-5 is installed within the base 2-10, and its output end is connected to the indexing plate 2-4. This allows for driving the indexing plate 2-4 while protecting the circumferential drive element 2-5, extending its service life and reducing operating costs. The circumferential drive element 2-5 can be a stable drive motor, offering precise positioning and fast, reliable operation.

[0031] In this embodiment, the gripping mechanism 3 is designed as a four-axis robot structure, which fully utilizes the flexibility and high-precision control capabilities of the four-axis robot to grasp and install the sealing ring 1. The whole process is highly automated, which can effectively improve the efficiency and safety of automated assembly.

[0032] The automated assembly device for ultrasonic gas meter sealing rings in this embodiment has the following specific working steps: the sealing ring 1 is loaded onto the material rack 2-1 located above the indexing plate 2-4. After the sealing ring 1 is loaded, the indexing plate 2-4 rotates to a fixed position under the action of the circumferential drive element 2-5. Then, the sealing ring 1 is accurately positioned by the photoelectric sensor. The gripping mechanism 3 then uses the robot's mechanical gripper to pick up the sealing ring 1 from the material rack 2-1 and then moves it around to the top of the above-mentioned transmission mechanism 4. The sealing ring 1 is then stably and reliably placed onto the tray fixture 4-1. The positioning is accurate, the action is fast and reliable, and the action consistency is good.

[0033] This embodiment presents an automated assembly device for ultrasonic gas meter sealing rings. This device features an ingenious structure, comprising a loading mechanism 2 for loading the sealing ring 1, a gripping mechanism 3 for clamping the sealing ring 1, and a transmission mechanism 4 for transferring gas meter components. The loading mechanism 2 includes a material rack 2-1, a push plate 2-2, a longitudinal drive component 2-3 that drives the push plate 2-2 to push the sealing ring 1 up and down along the height of the material rack 2-1, an indexing plate 2-4, and a circumferential drive element 2-5 that drives the indexing plate 2-4 to rotate circumferentially. The longitudinal drive component 2-3 pushes the push plate 2-2 to move the sealing ring 1 to the desired position. Then, the gripping mechanism 3 clamps the sealing ring 1 and installs it onto the tray fixture 4-1 on the transmission mechanism 4, achieving automated assembly with the gas meter components. The entire process requires no manual intervention, improving the production efficiency and assembly quality of ultrasonic gas meters, reducing labor costs and safety risks, enhancing the user experience, and facilitating the market promotion and use of the aforementioned automated assembly device for ultrasonic gas meter sealing rings.
