However, during use and maintenance, composite materials may be susceptible to structural damage, primarily from impact damage such as dropped tools, runway debris, hail, and bird strikes. These damage, such as cracks, notches, delamination, and holes, can significantly reduce the static and dynamic load-bearing performance of composite materials and, in severe cases, directly threaten the safety of composite parts.

[0003] At present, hot patching devices are mostly used for composite material repair. The hot patching device has a vacuum membrane and two tubes connected to the vacuum membrane. One tube is used to connect to a vacuum pump to create a negative pressure state between the vacuum membrane and the repair part, and the other tube is connected to the vacuum membrane to measure the air pressure. A vacuum membrane requires two tubes to achieve vacuuming and install a barometer to measure the air pressure, and the structure is relatively complicated. Summary of the Invention

[0041] Example 1

[0042] See also Figures 1 to 5As shown, the embodiment of the present application provides a composite material heating and pressurizing repair device with a simple pressure measurement structure, comprising: a housing 1 and a control assembly. The housing 1 has a cavity, and two vacuum interfaces 114 are provided on the housing 1. The control assembly is provided in the cavity. The control assembly includes a controller 7, a vacuum pump 8, an airflow seat 30, two barometers 60, and two first tubes 40. The vacuum pump 8 is electrically connected to the controller 7. The airflow seat 30 has two airflow channels 301. The two barometers 60 are both provided on the airflow seat 30. The two barometers 60 are respectively used to detect the air pressure in the two airflow channels 301. The two first tubes 40 are each connected to the airflow seat 30 at one end, and the two first tubes 40 are respectively connected to one of the airflow channels 301. The other ends of the two first tubes 40 are respectively connected to one of the vacuum interfaces 114. The vacuum pump 8 is connected to the airflow seat 30 via an exhaust pipe 50, and the vacuum pump 8 can selectively connect to any of the airflow channels 301 through the exhaust pipe 50.

[0043] The vacuum interface 114 can be connected to an exhaust pipe, which is connected to a vacuum membrane covering the repair area, so that the vacuum membrane maintains a negative pressure state and applies sufficient pressure to the repair area.

[0044] The vacuum pump 8 of the repair device provided in the embodiment of the present application can selectively connect to any air flow channel 301, supporting the simultaneous repair of two parts. The two barometers 60 can directly detect the air pressure, eliminating the need for a dedicated air pressure detection air pipe, thus simplifying the structure.

[0045] In the embodiment of the present application, the exhaust pipeline 50 includes two second pipelines 501, and the two second pipelines 501 are respectively connected to the two air flow channels 301. The exhaust pipeline 50 can selectively connect any one of the second pipelines 501 and the vacuum pump 8, while simultaneously disconnecting the other second pipeline 501 and the vacuum pump 8. When the repair device is used to repair two areas simultaneously, the exhaust pipeline 50 can cyclically and alternately control the vacuum pump 8 to connect the two second pipelines 501, so that the two second pipelines 501 are spatially isolated. The two second pipelines 501 can be alternately exhausted, and the two second pipelines 501 are not exhausted at the same time, so that the vacuum membrane covering the two repair areas can maintain a vacuum state.

[0046] In some possible embodiments, the exhaust pipeline 50 has a third pipeline 502 and a communicating vessel 503, the third pipeline 502 is connected to the vacuum pump 8, the communicating vessel 503 has a first interface and two second interfaces, the third pipeline 502 is connected to the first interface, the two second pipelines 501 are respectively connected to the corresponding second interfaces, and the communicating vessel 503 can selectively connect the first interface and any one of the second interfaces.

[0047] The communicating vessel 503 may be a three-way valve structure, which can enable the first interface to be alternately connected to the two second interfaces, so that the two second pipelines 501 perform the air extraction task alternately.

[0048] In some possible implementations, both second pipelines 501 are provided with a one-way valve 504, which only conducts airflow from the airflow seat 30 to the manifold 503. The one-way valve 504 prevents external air from entering the two second pipelines 501 at the manifold 503, thereby maintaining a stable negative pressure in the two second pipelines 501.

[0049] In some possible implementations, the connector 503 is electrically connected to the controller 7, and the controller 7 is used to control the connector 503 so that the first interface is alternately connected to the two second interfaces. The connector 503 can be a solenoid valve that can quickly switch states under the control of the controller 7.

[0050] In some possible embodiments, a first zone interface 111 and a second zone interface 112 are provided on the housing 1, the control component includes two voltage regulators 2, both of the two voltage regulators 2 are electrically connected to the controller 7, the first zone interface 111 and the second zone interface 112 are respectively electrically connected to the corresponding voltage regulators 2, and the first zone interface 111 and the second zone interface 112 are both used to electrically connect to the heating lamp terminal or the electric blanket terminal.

[0051] Optionally, a microwave heating interface 113 is provided on the box shell 1, and the control component also includes a magnetron and a first wave-to-phase converter, the magnetron is electrically connected to the voltage regulator 2, the input end of the first wave-to-phase converter is connected to the magnetron, and the output end of the first wave-to-phase converter is connected to the microwave heating interface 113, and the microwave heating interface 113 is used to electrically connect to the microwave heating terminal.

[0052] The present application provides a control method for repair equipment, including: the controller 7 controls the exhaust pipeline 50 to cyclically and alternately connect the two air flow channels 301, so that the vacuum pump 8 performs vacuum processing on the vacuum components connected to the two vacuum interfaces 114 respectively.

[0053] The vacuum component can be a vacuum membrane, which covers the area to be repaired. When the vacuum membrane is evacuated, it presses down on the patch placed on the repair area. Applying pressure to the patch through the vacuum membrane eliminates air holes and other defects. The heating terminal heats the repair area to accelerate the curing of the adhesive between the patch and the repaired area.

[0054] In some possible implementation schemes, during the operation of the vacuum pump 8, the two barometers 60 obtain the air pressure value in real time and send it to the controller 7. The controller 7 controls the operation of the exhaust pipeline 50 and the vacuum pump 8 according to the air pressure value detected by the barometer 60, so that the air pressure values ​​of the two vacuum components reach the set value.

[0055] The controller 7 first controls the two second pipes 501 of the exhaust pipe 50 to connect to the vacuum pump 8 frequently and alternately, and exhausts the vacuum membranes in the two repair areas respectively. When the air pressure in a certain vacuum membrane reaches the required value, the connection time between the second pipe 501 corresponding to the vacuum membrane whose air pressure has not reached the set value and the vacuum pump 8 can be extended, and the connection time between the second pipe 501 corresponding to the other vacuum membrane and the vacuum pump 8 can be shortened, so that the air pressure of the two vacuum membranes reaches the required value as soon as possible.

[0056] In some possible embodiments, the device includes a heating terminal, which can be any one or more of a heating lamp terminal, an electric blanket terminal, and a microwave heating terminal. The heating terminal can be electrically connected to the controller 7. The controller 7 first controls the vacuum pump 8 and the connecting valve 503 on the exhaust pipe 50 to adjust the vacuum pressure to a set value before controlling the heating terminal to turn on.

[0057] The vacuum pump 8 and exhaust line 50 of the repair equipment of the present application can operate independently of the heating terminal. This allows the vacuum film to be evacuated to the required value before the heating terminal is controlled to heat the repair area. This avoids the impact of insufficient vacuum in the early stage of heating and evacuation when heating and evacuation are performed simultaneously, thus improving process accuracy.
