[0002] For the full-automatic mechanical mouth-finding, cap-taking and capping device of a filling machine, it is mainly used to automatically open and seal containers on a production line. This device realizes the identification of the container mouth, the grasping of the bottle cap, and the accurate placement and screwing of the bottle cap on the container through the precise movement of the robotic arm. This process requires a high degree of precision and stability to ensure that each container can be properly processed.

[0003] However, in practical applications, there is a key problem: how to achieve precise positioning and stable operation of the robotic arm during the processes of mouth-finding, cap-taking, and capping, which involves multiple technical aspects such as the position control of the robotic arm, the force feedback mechanism, and the accuracy of the vision system. If these aspects are not properly solved, it may lead to the bottle cap not being accurately aligned with the container mouth or instability during the screwing process, thus affecting the overall production efficiency and product quality.

[0004] Therefore, solving this problem usually requires the comprehensive application of means such as precision mechanical design, sensor technology, and advanced control algorithms. Summary of the Utility Model

[0008] Preferably, the robotic arm is composed of multiple telescopic arms.

[0009] Preferably, the front sensor is a non-contact photoelectric sensor. By using high-precision photoelectric sensing technology and equipped with a fine-tuning mechanism, it can be accurately adjusted according to the sizes of different bottle mouths.

[0010] Preferably, the clamping mechanism adopts an elastic clamping design and automatically adapts to bottle caps of different sizes through elastic elements.

[0011] Preferably, the cap screwing device includes a rotatable bracket and a suction cup assembly mounted thereon. The suction cup assembly is composed of a plurality of small suction cups.

[0012] Preferably, the end effector of the robotic arm is designed as a multi-joint structure. A precision servo motor is provided at each joint. The end effector of the robotic arm is also equipped with an anti-slip gasket.

[0013] The utility model has the following advantages compared with the prior art:

[0014] Using a cylinder as the power source to drive the robotic arm to achieve precise position adjustment, enabling the robotic arm to accurately position the bottle mouth. Since the sensor can detect the position of the bottle mouth, the robotic arm can accurately stop moving and maintain its position. Since the cap screwing device is connected to the robotic arm through a connecting plate and is equipped with a suction cup and a clamping mechanism, the opening and closing actions of the cap can be realized. Since the fixing device ensures the stability of the suction cup and the cap screwing device, operation errors are avoided. Therefore, this series of precisely coordinated actions ensure that the fully automatic mechanical bottle mouth searching, cap picking and capping device can efficiently and accurately complete the whole process from searching for the bottle mouth, picking the cap, filling to capping, greatly improving the production efficiency and the automation level.

[0020] Referring to Figure 1 and Figure 2 , a fully automatic mechanical mouth-finding, cap-taking and capping device, comprising a mounting plate 8, the mounting plate 8 is fixedly connected with a cylinder 1, the cylinder 1 is fixedly connected with a robotic arm 2, the end of the robotic arm 2 is fixedly connected with a front sensor 3, the robotic arm 2 is fixedly connected with a connecting plate, the connecting plate is connected with a capping device 5, the bottom of the capping device 5 is connected with a clamping mechanism 4, the bottom of the connecting plate is connected with a suction cup assembly 9, and the suction cup assembly 9 is connected with a fixing device 6. The outer side wall of the mounting plate 8 is fixedly connected with a canning device 7.

[0021] The robotic arm 2 is composed of multiple telescopic arms. In this way, the flexibility and extension range of the robotic arm 2 can be increased, and the problem of difficult accurate grasping of objects in a narrow space is solved.

[0022] The front sensor 3 is a non-contact photoelectric sensor. By using high-precision photoelectric sensing technology and equipped with a fine-tuning mechanism, it can be accurately adjusted according to the sizes of different bottle mouths, improving the sensing accuracy and reaction speed, and solving the problem that the accuracy of the contact sensor is easily affected by wear.

[0023] The clamping mechanism 4 adopts an elastic clamping design and automatically adapts to caps of different sizes through elastic elements.

[0024] The capping device 5 includes a rotatable bracket and a suction cup assembly 9 mounted thereon. The suction cup assembly 9 is composed of multiple small suction cups. The suction cup assembly 9 is connected to the bracket through an elastic connecting piece. A torque control mechanism is provided inside the capping device 5. By precisely controlling the torque size during the capping process, it is ensured that the cap is neither too loose nor too tight, solving the problem that the traditional capping device 5 cannot precisely control the torque.

[0025] The end effector of the robotic arm 2 is designed as a multi-joint structure, and a precision servo motor is provided at each joint, which can achieve precise control of multiple degrees of freedom, making the robotic arm 2 more flexible and free when performing actions such as mouth-finding, cap-taking, and capping, improving the operation accuracy and efficiency.

[0026] The specific working principle of the present utility model is as follows:

[0027] In the initial state, when this device is in use, first, the mounting plate 8 serves as the basic support structure for the entire device, ensuring that each component can be stably installed and work in coordination. The cylinder 1 fixedly connected to the mounting plate 8 serves as the main power source. Driven by its telescopic movement, it drives the robotic arm 2 fixedly connected to it to achieve precise position adjustment. A front sensor 3 is fixedly connected to the end of the robotic arm 2. This front sensor 3 is used to detect the specific position of the target bottle mouth, thereby realizing the precise positioning of the robotic arm 2. Once the front sensor 3 detects the position of the bottle mouth, the robotic arm 2 will stop moving and remain in the current position. At the same time, a capping device 5 is also installed on the connecting plate fixedly connected to the robotic arm 2. This device is connected to the robotic arm 2 through the connecting plate, and a suction cup assembly 9 is also connected to the bottom of the connecting plate. After the front sensor 3 completes the bottle mouth positioning, the capping device 5 will move above the bottle mouth. At this time, the suction cup assembly 9 aligns with the bottle cap and adsorbs the bottle cap through negative pressure. Subsequently, the capping device 5 starts to rotate, and uses the clamping mechanism 4 at its bottom to realize the opening or closing action of the bottle cap. After completing the opening action, the device can perform subsequent filling processes; after filling is completed, the capping device 5 tightens the bottle cap again through a rotational movement to complete the entire automated operation process. During the whole process, the fixing device 6 ensures the stability of the suction cup assembly 9 and the capping device 5 during the execution of tasks, avoiding operation errors caused by external interference. This series of precisely coordinated actions ensures that the fully automatic mechanical bottle mouth searching, cap taking, capping device can efficiently and accurately complete the whole process from searching for the bottle mouth, taking the cap, filling to capping, greatly improving the production efficiency and automation level.
