For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment provides a welding tool using an RF SMP connector, including: a fixing part 1 and an RF SMP connector 7, the RF SMP connector 7 is used to output the frequency adjusted by the angle spectrum method, the fixing part 1 can be detachably pressed against the RF SMP connector 7, and the fixing part 1 can be pressed against or loosened against the RF SMP connector 7 by adjusting the screw 11.

[0040] Combination Figure 1 and Figure 2The fixing member 1 has a through hole 3, and the RF SMP connector 7 has a pin 9. A portion of the pin 9 in the RF SMP connector 7 is inserted into the through hole 3. The pin 9 in the through hole 3 is connected to the frequency transmitter, the frequency transmitter is connected to the frequency regulator, and the frequency regulator is connected to the electrical signal transmitting module. The other portion of the pin 9 passes through the solder 8 in the RF SMP connector 7.

[0041] A welding groove cup mouth 6 is opened on the workpiece 5, and the RF SMP connector 7 is inserted into the welding groove cup mouth 6. Threaded holes 10 are opened on both sides of the workpiece 5. Screws 11 pass through the connecting block 2 of the fixing part 1 and cooperate with the threaded holes 10. The fixing part 1 is abutted against or loosened against the RF SMP connector 7 by adjusting the screws 11, wherein the abutment block 4 of the fixing part 1 abuts against the RF SMP connector 7.

[0042] Example 2

[0043] Based on Example 1, Figure 1-Figure 2 As shown, the ejector pin 9 in the through hole 3 is connected to the frequency transmitter, the frequency transmitter is connected to the frequency regulator, and the frequency regulator is connected to the electric signal transmitting module. The electric signal transmitting module transmits an electric signal with a frequency, the frequency regulator regulates the electric signal with a frequency, and the frequency transmitter transmits the electric signal with the regulated frequency to the frequency transmitter, and the frequency transmitter enables the ejector pin 9 to melt the solder 8 in the welding groove cup 6.

[0044] In addition, the solder 8 in the RF SMP connector 7 falls into the soldering groove 6, that is, the solder 8 in the RF SMP connector 7 falls into the soldering groove 6 at the left end of the ejector pin 9 to be melted. During the rightward movement of the RF SMP connector 7, the solder 8 in the RF SMP connector 7 gradually falls into the soldering groove 6 at the left end of the ejector pin 9, so that the solder 8 is welded on the workpiece 5.

[0045] Example 3

The air tightness of the welding is ensured because the RF SMP connector 7 moves to the right, and the RF SMP connector 7 is inserted into the welding groove cup mouth 6, and the RF SMP connector 7 almost discharges the air in the welding groove cup mouth 6.

[0047] Example 4

[0048] Based on Example 1, Figure 3 As shown, this embodiment provides a welding method using a radio frequency SMP joint, comprising the following steps:

[0049] Step 1): Place the workpiece 5 on a heating table, heat the heating table, and observe the welding groove cup 6 on the workpiece 5 after the workpiece 5 is preheated by the heating table;

[0050] Step 2): Place the RF SMP connector 7 into the welding cup 6;

[0053] Step 5): After the welding is completed, turn off the heating table, put on protective gloves, remove the workpiece 5 and place it on the heat sink. After the workpiece 5 is completely cooled, use X-ray to inspect the welding effect of the solder 8 on the workpiece 5.

[0054] Specifically, in step 1), after the workpiece 5 is preheated by the heating table, it is observed whether the shape of the welding groove cup 6 on the workpiece 5 changes.

[0055] In step 2), if the shape of the welding slot cup mouth 6 does not change, the RF SMP connector 7 is placed in the welding slot cup mouth 6, otherwise, if the shape of the welding slot cup mouth 6 changes, the RF SMP connector 7 is no longer placed in the welding slot cup mouth 6.

[0056] In step 3), the material of solder 8 is selected as OCr18N i 10T i , the soldering process of solder 8 does not stick to the solder.

[0057] In step 4), the pin 9 in the radio frequency SMP connector 7 is connected to the frequency transmitter, and the frequency transmitter is connected to the frequency regulator.

[0058] The frequency regulator uses the angle spectrum method to adjust the frequency. The angle spectrum method is as follows (1):

[0059] (1);

[0060] in, is the angle, is the frequency corresponding to the selected angle, is a vector, is the vector direction, is the selected vector, is the frequency corresponding to the selected vector and the selected angle, is the output frequency.

[0061] Example 5

[0062] Based on Example 4, Figure 4 As shown, In is the direction of the vector (i.e. the direction pointing outward from the origin 0), and the vector is τ 0 When ω 0 is 0°, when the vector is τ 0 , and ω 0 When ω is 0°, it is the starting position of the output frequency. 1 When , the vector is τ 1 , when ω is ω 2 When , the vector is τ 2 , and so on.

[0063] Each ω corresponds to a vector τ, and each vector τ corresponding to ω represents an output frequency. Therefore, different ω corresponds to different vectors τ, and different vectors τ represent output frequencies of different sizes.

[0064] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
