[0016] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figures 1 to 3 As shown: An ultrasonic plastic repair device includes a housing 1, a power module 2 is arranged inside the housing 1, the power module 2 is connected to the input voltage stabilizing element 4 through a transformer 3, the input voltage stabilizing element 4 is electrically connected to the generating piece 5, a heat sink 6 is provided on the back side of the generating piece 5, a cooling fan 7 is provided on the housing 1 corresponding to the position of the heat sink 6, a display screen and a control panel are provided on the outside of the housing 1, and the display screen and the control panel are both connected to the PLC control module located in the housing 1,

[0017] A frequency control module 8, a temperature control module 9, a timing protection module 10, a circuit protection module 11 and an alarm module 12 are also provided in the housing 1, and the frequency control module 8, the temperature control module 9, the timing protection module 10, the circuit protection module 11 and the alarm module 12 are all uniformly controlled by the PLC control module 9.

[0018] The housing 1 is also provided with a welding gun circuit 13, which contains four signal lines. One end of the welding gun circuit 13 is connected to the ultrasonic welding gun 14, and two signal lines at the other end are connected to the PLC control module (one input and one output), and the other two signal lines are connected to the generator 5 (one input and one output).

[0019] The welding head is a fusion welding head 15 , or a shallow penetration welding head 16 , or a deep penetration welding head 17 .

[0020] The working process of the ultrasonic plastic repair device of the embodiment of the present utility model is as follows: when it is necessary to use the device to perform welding operations on plastic products, first, according to the current needs, a suitable welding head (fusion welding head 15, shallow puncture welding head 16 or deep puncture welding head 17) is selected, and the device is started through the control panel. The ultrasonic wave emitted by the generating piece 5 is transmitted to the ultrasonic welding gun 14 through the welding gun circuit 13, and the high-frequency vibration is output by the welding head. The end of the welding head is pressed against the surface of the plastic product to be welded. Under the action of the high-frequency vibration, the part of the plastic product that contacts the end of the welding head quickly heats up and melts. After the welding head is removed, the plastic products cool and are bonded together.

[0021] During the above working process, the heat generated by the generator 5 is transferred to the heat sink 6, and the cooling fan 7 cools the heat sink 6 to ensure that the generator 5 is always at a relatively suitable temperature.

[0022] The frequency control module 8 can control the operating frequency of the ultrasonic welding gun 14 through the PLC module, and the temperature control module 9 can detect the temperature inside the shell 1 during operation. If the temperature exceeds the standard, it will send a signal to the PLC control module, and the PLC control module will automatically control the device to stop working and send an audible / visual warning message through the alarm module 12;

[0023] The timing protection module 10 can set the working time of the device. If the continuous working time exceeds the set time, it will send a signal to the PLC control module. The PLC control module automatically controls the device to stop working and sends an audible / visual warning message through the alarm module 12.
