Description

Technical Field

[0001] This utility model relates to the field of fusion head technology, specifically a fusion head for a fusion machine. Background Technology

[0002] A fusion machine is a device that uses a high-frequency electric field to fuse materials. It heats the surface of the material by a high-frequency electric field until it reaches its melting point, and then fuses it. The advantages of a fusion machine are its fast, efficient, and precise fusion capabilities. The fusion head is the device in the fusion machine that directly contacts the material being processed and melts and fuses the material through thermal energy or mechanical action.

[0003] In the prior art, such as the fusion head for a PCB board fusion machine proposed in patent application number "CN201920613362.6", the magnetic flux reaction between the fusion head and the PCB board circuit can be effectively blocked, thereby reducing the width of the board edge and improving the utilization rate of PCB board material, thus improving the fusion efficiency and effectively solving the problem that traditional fusion devices are difficult to adapt to new requirements.

[0004] However, in the aforementioned patent application, when the fusion head fuses the product, the internal magnetic core temperature rises. After the fusion is completed, it is impossible to cool it down by blowing air. The cooling speed of the fusion head is slow, and the continuous high temperature damages the fusion head, thereby affecting its service life. Utility Model Content

[0013] The beneficial effects of this utility model are:

[0014] In this invention, when the fusion head is in use, the internal magnetic core generates a magnetic field for heating, and the temperature sensing area collects the temperature in real time. The heating current of the internal magnetic core is adjusted according to the actual temperature. When heating is complete, air is blown through the air pipe on the air blowing block to cool down the head, thereby accelerating the cooling speed of the fusion head, avoiding the effects of continuous high temperature, and effectively extending its service life. The entire fusion head structure is standardized, and the fixing base, base, and cover are precisely controlled. The internal magnetic core is accurately positioned, the temperature sensing line is in the center area, and the temperature response is sensitive.

[0026] When the product is fused using the fusion head, the internal magnetic core 7, which is fixed inside the main body 2 by the internal fixing seat 8, generates a magnetic field to heat the product when the power is turned on. The temperature sensing area in the groove 4 collects the temperature in time and adjusts the heating current of the internal magnetic core 7 according to the actual temperature. When the heating is completed, the air pipe 6 on the air blowing block 5 blows air to cool down the product, thereby accelerating the cooling speed of the fusion head, avoiding the effects of continuous high temperature, and effectively extending its service life.
