[0021] like Figure 1As shown, a foaming filling system of a preferred embodiment of the utility model is used to fill foam into a cavity of a vehicle body 1, and the vehicle body 1 has a filling port connected to the cavity. The foaming filling system includes: a filling device 2, a visual positioning device 3, a visual detection device and a control device; the visual positioning device 3 is used to determine the position of the filling port of the vehicle body 1; the filling device 2 includes a driving mechanism 21, a filling gun 22, a storage tank 23 and a feeding mechanism 24; the filling gun 22 is connected to the storage tank through the feeding mechanism 24 23 is connected, the storage tank 23 is used to store foaming material, the feeding mechanism 24 is used to transport the foaming material in the storage tank 23 to the filling gun 22, the filling gun 22 is installed on the driving mechanism 21, and the driving mechanism 21 is used to move the filling gun 22 to the filling port; the visual detection device is used to take pictures and record the filling port; the visual positioning device 3, the driving mechanism 21, the filling gun 22, the feeding mechanism 24 and the identification and recording device are respectively electrically connected to the control device.

[0022] Based on the above scheme, the system first confirms the position of the filling hole of the vehicle body 1 through the visual positioning device 3, and then moves the filling gun 22 to the position of the filling hole through the driving mechanism 21, and the feeding mechanism 24 inputs the foaming material in the storage tank 23 into the filling hole to realize the automatic filling function, thereby ensuring the filling quality. In addition, during the filling process, the visual detection device records the situation of the filling port in real time, and transmits the recorded data to the control device for backup. When quality problems occur, quality backtracing can be carried out in time through the recorded data. In addition, during the filling process, the visual positioning device 3, the driving mechanism 21, the filling gun 22 and the feeding mechanism 24 will also feed back data to the control device in real time to facilitate quality problem analysis.

[0026] In some embodiments, multiple storage tanks 23 are included, and the multiple storage tanks 23 are respectively used to input different materials into the filling gun 22. Since the foaming material is usually composed of a mixture of multiple raw materials, materials of different components are mixed on the filling gun 22.

Specifically, it is determined whether there is foaming overflow or leakage at the foaming position by comparing the photos taken by the camera.

[0031] Optionally, for ease of use, the control device is a PLC controller.

[0032] like Figure 1 As shown, for ease of use, a cleaning device is also included, which is electrically connected to the control device and is used to clean the filling gun 22. When the filling gun 22 completes filling, it will move to the cleaning device for cleaning to avoid clogging of the filling gun 22.

[0033] In summary, the embodiment of the utility model provides a foaming filling system, which first confirms the position of the filling hole of the vehicle body 1 through the visual positioning device 3, and then moves the filling gun 22 to the position of the filling hole through the driving mechanism 21, and the foaming material in the storage tank 23 is input into the filling hole by the feeding mechanism 24 to realize the automatic filling function, thereby ensuring the filling quality, and during the filling process, the visual detection device records the situation of the filling port in real time, and transmits the recorded data to the control device for backup.
