[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The present invention provides Figures 1 to 5 The intelligent variable frequency battery terminal welding tool shown includes:

[0036] Electric soldering iron body;

[0037] The electric soldering iron body includes a handle 1, a soldering core 2, and a soldering tip 3. One end of the soldering core 2 is plugged into the interior of the handle 1. A power cord 4 extends outward from the end of the handle 1 away from the soldering core 2. The soldering tip 3 is plugged into the interior of the soldering core 2 away from the handle 1. The soldering tip 3 is made of T12 alloy steel and has a chrome-plated surface. The soldering core 2 has a dual power mode of 500W / 200W and an adjustable temperature of 200-450°C.

[0038] Heating components;

[0039] The soldering iron core 2 includes a hollow alumina ceramic core 5, an electric heating wire 6 is wound around the outside of the alumina ceramic core 5, and a control circuit board 7 is provided inside the handle 1. Both ends of the electric heating wire 6 are connected to the control circuit board 7, and the control circuit board 7 is connected to the power cord 4;

[0040] Temperature control components;

[0041] A control button 8 is provided inside the handle 1, and the control button 8 extends outward to the outside of the handle 1. The control button 8 is located at the thumb position on the handle 1 for easy operation. A thermocouple 9 is also provided inside the handle 1. The thermocouple 9 is inserted into the interior of the alumina ceramic core 5 and contacts the soldering iron tip 3. The thermocouple 9 is connected to the control circuit board 7. An OLED screen 10 is provided on the outside of the handle 1, and the OLED screen 10 is connected to the control circuit board 7.

[0042] protective devices;

[0043] The heat insulation tube 11 is sleeved on the outside of the soldering iron core 2 and is fixedly connected to the alumina ceramic core 5 by mounting screws. The heat insulation tube 11 is made of cobalt oxide ceramic, which has good thermal insulation performance and high strength.

[0044] heat dissipation components;

[0045] The heat-insulating tube 11 is provided with a heat-dissipating fin 12 inside. The heat-dissipating fin 12 passes through the heat-insulating tube 11 and extends outward. The surface of the heat-insulating tube 11 is also provided with a plurality of heat-dissipating holes 13.

[0046] By cooperating with the control circuit board 7 and the control button 8, constant temperature heating control can be achieved. Then, the heat insulation tube 11 is used to isolate the temperature outside the soldering iron core 2, locking the temperature inside the alumina ceramic core 5, so as to facilitate and quickly heat the soldering iron tip 3. In conjunction with the three-speed temperature adjustment of the control button 8, different temperature controls can be achieved. At the same time, when in standby mode, the heat sink 12 and the heat dissipation hole 13 can assist in cooling to prevent the soldering iron tip 3 from overheating, thereby realizing intelligent frequency conversion control.

[0047] Among them, such as Figure 3 and Figure 5 As shown:

[0048] A storage groove 14 is provided on the outer side of the alumina ceramic core 5, and the electric heating wire 6 is located in the storage groove 14. The setting of the storage groove 14 facilitates the storage of the electric heating wire 6, thereby preventing the electric heating wire 6 from sliding on the outer surface of the alumina ceramic core 5, resulting in temperature non-concentration and affecting the heating efficiency of the soldering iron tip 3.

[0049] Further, such as Figure 3-4 As shown:

[0050] The outside of the alumina ceramic core 5 is wrapped with a high-temperature resistant film net 15, and the outside of the high-temperature resistant film net 15 is wrapped with a limiting iron wire 16. A limiting groove 17 is provided on the outside of the alumina ceramic core 5, and the limiting groove 17 is located on the inner side of the inner high-temperature film net. Through the winding of the high-temperature resistant film net 15, not only the electric heating wire 6 can be isolated, but also the heat can be prevented from diffusing outward quickly, and the soldering iron tip 3 is heated and heated first. Similarly, the setting of the limiting groove 17, in conjunction with the limiting iron wire 16, is used to limit and fix the high-temperature resistant film net 15 to prevent translational sliding.

[0051] Preferably, Figure 5 As shown:

[0052] A magnet ring 18 is fixedly embedded in the inner cavity of the alumina ceramic core 5, and the soldering iron tip 3 is attached to the inner wall of the magnet ring 18. Through the cooperation of the magnet ring 18, the soldering iron tip 3 can be magnetically attracted to the inside of the alumina ceramic core 5 to prevent the soldering iron tip 3 from falling. It is also convenient to replace the soldering iron tip 3 and use different soldering iron tips 3 for welding.

[0053] It is worth noting that if Figure 1-2 As shown:

[0054] A TPE soft rubber head 19 is provided on the outer side of the handle 1 near the soldering iron core 2. A through hole is provided on the TPE soft rubber head 19 for use with the control button. By providing the soft rubber head on one end of the handle 1, the comfort of the operator's hand grip is improved to avoid soreness caused by holding the handle 1 for a long time.

[0055] In a further preferred embodiment, Figure 2 As shown:

[0056] A counterweight ring 20 is installed inside the handle 1. The counterweight ring 20 is located at the end of the handle 1 away from the soldering iron core 2. Through the setting of the counterweight ring 20, the center of gravity of the electric soldering iron body can be conveniently adjusted so that the center of gravity is located inside the handle 1, effectively preventing the end of the soldering iron tip 3 of the electric soldering iron body from falling downward, causing the soldering iron tip 3 to contact an object.

[0057] In addition, if Figure 1-2 As shown:

[0058] The OLED screen 10 is tilted at an angle of 15 degrees. By setting the angle of the OLED screen 10, when the operator operates the soldering iron body, the OLED screen 10 is just folded in half over the operator's eyes, making it convenient to observe and control the temperature.

[0059] In this embodiment, if Figure 4 As shown:

[0060] The inner cavity of the thermal insulation tube 11 is provided with two groups of internal threaded tubes 21. The mounting screws pass through the internal threaded tubes 21 and are threadedly connected to the alumina ceramic core 5. The end of the alumina ceramic core 5 is provided with a guide groove 22 for sliding with the internal threaded tube 21. The internal threaded tube 21 slides along the guide groove 22, and then the thermal insulation tube 11 is connected to the alumina ceramic core 5 using the mounting screws to maintain the temperature of the thermal insulation tube 11 and prevent the thermal insulation tube 11 from falling off, which may easily cause burns.

[0061] In addition, if Figure 2 As shown:

[0062] A slot 23 is provided at the end of the handle 1 away from the power cord 4, and one end of the insulation tube 11 is clamped in the slot 23. An air chamber is formed between the insulation tube 11 and the alumina ceramic core 5. By providing the slot 23 at one end of the handle 1, the other end of the insulation tube 11 is limited and fixed to prevent the insulation tube 11 from contacting the alumina ceramic core 5, which would cause the insulation tube 11 to fail to achieve the purpose of thermal insulation protection.

[0063] In this embodiment, if Figure 3-4 As shown:

[0064] A threaded cap 24 is provided at one end of the thermocouple 9, and the threaded cap 24 is threadedly connected to the end of the alumina ceramic core 5. Through the setting of the threaded cap 24, the thermocouple 9 is conveniently installed at one end of the alumina ceramic core 5, ensuring that the thermocouple 9 can stably and quickly detect the stability of the soldering iron tip 3.

[0065] During specific use, a suitable soldering iron tip 3 is selected as needed, and the soldering iron tip 3 is inserted from one end of the heat-insulating tube 11 and then into the interior of the alumina ceramic core 5. When one end of the soldering iron tip 3 is inserted into the magnet ring 18, the soldering iron tip 3 is adsorbed and fixed by the magnet ring 18. At this time, one end of the soldering iron tip 3 is located inside the electric heating wire 6. After connecting the power cord 4 to the power supply, turn on the control button 8, select the appropriate temperature through the control button 8, and then control the circuit board 7 to control the electric heating wire 6 to energize. Then, the electric heating wire 6 heats the alumina ceramic core 5 and the alumina ceramic core 5 heats up quickly and preferentially heats the internal soldering iron tip 3, so that the temperature of the soldering iron tip 3 rises rapidly. At the same time, the thermocouple 9 is in contact with the soldering tip 3, and the temperature of the soldering tip 3 is detected in real time, which can be fed back to the control circuit board 7 for effective control. At the same time, the high-temperature resistant film net 15 on the outside of the electric heating wire 6 protects the electric heating wire 6 and locks the heat to maintain the temperature inside the alumina ceramic core 5, thereby achieving constant temperature heating to prevent the temperature of the soldering tip 3 from dropping with use. At the same time, during use, the user can observe the temperature value on the OLED screen 10 at a suitable angle. After the device is in standby mode, the heat sink 12 and the heat dissipation holes 13 on the insulation tube 11 perform auxiliary heat dissipation processing to reduce the temperature of the soldering tip 3, realize energy management, and avoid energy waste.
