Description

Technical Field

[0001] This utility model relates to the field of high-frequency heating coils, and in particular to a spiral tube-type high-frequency induction heating coil that is easy to connect and disconnect. Background Technology

[0002] Induction heating can heat specific parts of objects and can be applied to surface hardening, melting, hard soldering, soft soldering, and heating objects to work with other objects. Induction heating is widely used in the semiconductor industry to heat silicon or other semiconductor materials and is commonly used in many low-cost industrial applications. Its main component is a high-frequency induction heating coil, mostly of the spiral tube type. Traditional spiral tube high-frequency heating coils can only be removed axially after heating, and other shapes of high-frequency heating coils are not very efficient, which limits the use of high-frequency heating. Some existing methods use the spiral tube to be split into two radially to solve the cooling problem. However, the separation and closure of the two sets of insulating tubes under mechanical movement requires a large force to ensure that their connection ends are tightly pressed together. Otherwise, the contact will be poor and the conductivity will be lost. Utility Model Content

The insulating high-temperature resistant assembly ring is composed of two semi-rings. Liquid inlet and outlet holes are opened on the outer arc tube walls at both ends of the semi-circular arc tubes. The elastic contact head is composed of a groove end block and a spring cavity groove provided on one side of the groove end block. A bullet is inserted into the spring cavity groove. One end of the bullet has a narrow head that extends to the outside of the spring cavity groove. Several ring-shaped blocking arc heads are installed on the groove edge of the spring cavity groove. A spring is pressed between the bullet and the inner groove wall of the spring cavity groove.

[0006] Furthermore, terminals are installed on both ends of the assembled solenoid.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5 As shown, a spiral tube type high-frequency induction heating coil that is easy to assemble and disassemble consists of an insulating high-temperature resistant assembly ring 1 and an assembly solenoid 2 installed on the inner ring surface of the insulating high-temperature resistant assembly ring 1.

[0022] The assembled solenoid 2 is composed of several semi-circular arc tubes 4 arranged in a spiral shape. The splicing end of the semi-circular arc tubes 4 is equipped with an elastic contact head 6. The insulating and high-temperature resistant assembly ring sleeve 1 is composed of two semi-ring sleeves. When the two semi-ring sleeves are assembled, they drive several semi-circular arc tubes 4 to form the assembled solenoid 2.

[0023] Both ends of the semi-circular arc tube 4 are provided with inlet and outlet holes 5 on the outer arc tube wall for circulating injection and discharge of coolant, thereby controlling the tube temperature.

[0024] The elastic contact head 6 consists of a groove end block 61 and a spring cavity groove 65 disposed on one side of the groove end block 61. A bullet head 62 is inserted into the spring cavity groove 65. One end of the bullet head 62 has a narrow head that extends to the outside of the spring cavity groove 65. Several annularly distributed blocking arc heads 63 are installed on the groove edge of the spring cavity groove 65. The ends of the blocking arc heads 63 extend inward to facilitate limiting the bullet head 62, so that the narrow head is exposed. The remaining part is blocked in the spring cavity groove 65 to achieve the limiting. A spring 64 is pressed between the bullet head 62 and the inner groove wall of the spring cavity groove 65.

[0025] like Figures 1-5 As shown, this utility model also discloses the following more optimized specific structures:

[0026] The two ends of the assembled solenoid 2 are equipped with terminals 3 for external wiring.

[0027] The inner wall of the semi-circular sleeve is provided with a semi-circular groove that matches the semi-circular tube 4. The semi-circular tube 4 is embedded in the semi-circular groove. The semi-circular sleeve is made of insulating, high-temperature resistant material with certain mechanical strength.

[0028] The groove end block 61 is welded to the splice end of the semi-circular arc tube 4.

[0029] A spring groove is provided on one side of the bullet 62, and one end of the spring 64 extends into the spring groove to facilitate the limiting and stabilizing of the internal spring.

The main body consists of an insulated high-temperature resistant assembly ring 1 and an assembly solenoid 2. By separating and assembling the two semi-circular rings, several semi-circular tubes 4 can be quickly assembled and separated, and the assembly solenoid 2 can be separated and assembled. The assembly ends of the semi-circular tubes 4 are equipped with elastic contact heads 5 with a certain degree of elasticity and extension, which ensures good contact between the semi-circular tubes 4 on the assembly solenoid 2. Each semi-circular tube 4 is provided with two liquid inlet and outlet holes 5 for the inlet and outlet of coolant, ensuring temperature control of the tube.
