Description

Technical Field

[0001] This utility model relates to the field of soldering iron technology, specifically to an intelligent soldering iron with adjustable lighting brightness. Background Technology

[0002] Soldering irons, as a welding tool, are widely used in the production, testing, and repair of electronics. However, as electronic components and circuit boards become smaller and smaller, the difficulty of soldering is also increasing. Especially in low-light conditions, although indoor lighting can provide illumination, factors such as the distance of the light source, human obstruction, and the shadow cast by the soldering iron itself can interfere with the accuracy and precision of the soldering.

[0003] While some existing soldering irons have lighting functions, most of them are mounted on the outside of the soldering tip, making them easily obstructed by the human body (such as the user's hand) or the soldering tip itself. A smaller number have the lighting located inside the soldering iron handle and pointing towards the tip, but these typically use high-brightness LEDs with a specific beam angle to achieve concentrated brightness. However, these LEDs are not heat-resistant, and the existing lighting is connected or in contact with the soldering iron tip, causing heat to be quickly transferred to the LEDs. Combined with the slow heat dissipation of LEDs, this makes them prone to damage from overheating. Furthermore, existing lighting is only for illumination and lacks other functions. It is also impossible to control the lighting or to synchronize it with the soldering iron tip, resulting in poor controllability and an inability to achieve intelligent control of the LEDs as needed. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by providing an intelligent soldering iron with adjustable lighting brightness, effectively solving the problems of existing soldering irons lacking built-in lighting functions or having limited LED light beads that cannot be intelligently controlled.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model discloses an intelligent soldering iron with adjustable illumination brightness, comprising a soldering iron handle and an illumination element disposed on the soldering iron handle. The soldering iron handle comprises a handle shell, a soldering iron core with a soldering tip, a circuit board, and an intelligent control module. The circuit board is disposed within the handle shell, which has an open end. The open end is configured to allow the connecting end of the soldering iron core to extend into the handle shell and connect to the circuit board. A first gap exists between the inner wall of the open end and the soldering iron core. The illumination element is configured as a surface-mount LED disposed at the first gap and illuminating the soldering tip. The surface-mount LED is connected to the circuit board. The intelligent control module is disposed on the circuit board to independently control the working state of the surface-mount LED and the working state of the soldering iron core.

[0007] In some embodiments, the patch LED is configured as an annular sheet whose outer contour can be inserted into the open end and whose inner hole allows the soldering iron tip to pass through, with the illumination chips on the patch LED spaced around the surface of the annular sheet facing the soldering iron tip.

[0008] Furthermore, the inner hole of the surface-mount LED is configured to allow the soldering iron core to pass through and to form a second gap between the LED and the soldering iron core.

[0009] In some embodiments, the circuit board is configured as a plate structure extending along the length of the inner cylinder of the handle housing, and slots are symmetrically provided on both sides of the inner cylinder wall of the handle housing, into which the two sides of the circuit board are inserted.

[0010] Furthermore, the circuit board extends two connection pins at the end near the opening, and the connection pins are connected to the connection holes on the surface-mount LED.

[0011] In some embodiments, the circuit board has a connection port on the board body near the opening end, and a connector is connected to the connection port. The soldering iron tip extends into the handle housing and connects with the connector.

[0012] In some embodiments, a diffuser is also included, which is mounted at the opening end and is closer to the soldering tip than the surface-mount LED.

[0013] In some embodiments, the intelligent control module includes a lighting control unit and a welding control unit. The lighting control unit is configured to intelligently control the brightness, start / stop, standby mode, automatic / manual mode, and fault alerts of the patch LEDs via buttons located on the handle housing.

[0014] In some embodiments, a central focusing sleeve is also included, which is connected to the open end of the handle housing, and at least a portion of the focusing sleeve extends from the surface-mount LED toward the soldering tip to form a focusing tube portion.

[0015] Furthermore, the focusing sleeve includes a small-diameter end having the focusing tube portion, a large-diameter end for accommodating the patch LED, and a connecting end for connecting to the handle housing, wherein the large-diameter end is located between the small-diameter end and the connecting end.

[0016] The beneficial effects of this utility model are:

[0017] 1. Because this utility model uses a surface-mount LED placed in the first gap between the inner wall of the opening and the soldering iron tip, and the lighting direction is towards the soldering iron tip, it will not be blocked by the human body (such as the user's hand) or the soldering pen itself during use. Therefore, it can provide shadowless lighting for soldering, thereby improving the accuracy or precision of soldering.

[0018] 2. Since the surface mount LED is connected to the circuit board and there is no connection between it and the soldering iron core, the heat from the soldering iron core is not easily conducted to the surface mount LED. Moreover, surface mount LEDs have the characteristics of high thermal conductivity and low thermal resistance, so it is easier to handle heat dissipation problems and prevent the surface mount LED from being in a high-temperature state, thereby improving the lifespan of the surface mount LED.

[0019] 3. Furthermore, since the soldering pen is equipped with an intelligent control module, which independently controls the working status of the surface mount LED and the soldering iron core, the working status of the surface mount LED can be intelligently adjusted and controlled, such as adjusting brightness, standby status, fault reminders, etc. Moreover, the working status of the surface mount LED is not affected by the working status of the soldering iron core, and can also be linked according to the working status of the soldering iron core or the usage status of the intelligent soldering iron.

[0020] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "fitting," "connected," "linked," and "installed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] The following description, in conjunction with the accompanying drawings, describes the intelligent soldering iron with adjustable lighting brightness according to this invention.

[0050] like Figure 1 and Figure 6As shown, this utility model relates to an intelligent soldering iron with adjustable illumination brightness, including a soldering iron handle 100 and an illumination body disposed on the soldering iron handle 100. The soldering iron handle 100 includes a handle shell 1, a soldering iron core 2 with a soldering iron tip 21, a circuit board 3, and an intelligent control module 4. It can be understood that the soldering iron handle 100 is an intelligent soldering iron, and the soldering iron handle 100 can be powered by a wire connection or can be wirelessly operated by a built-in battery. The circuit board 3 is disposed inside the handle shell 1, and the handle shell 1 has an open end 11. The open end 11 is configured as a passage for the connection end 73 of the soldering iron core 2 to extend into the handle shell 1 and connect with the circuit board 3. There is a first gap 12 between the inner wall of the open end 11 and the soldering iron core 2, that is, the diameter of the passage is slightly larger than the diameter of the soldering iron core 2, and the soldering iron core 2 is located in the middle of the open end 11, thereby forming the first gap 12. The illumination source is a surface-mount LED 5 positioned at the first gap 12 with its illumination direction facing the soldering iron tip 21. Therefore, it is not obstructed by the human body (such as the user's hand) or the soldering iron handle 100 during use, thus providing shadowless illumination for soldering and improving accuracy and precision. Furthermore, the surface-mount LED 5 is connected to the circuit board 3, and has no connection to the soldering iron tip 2, making it difficult for heat from the tip to be conducted to the LED 5. The surface-mount LED 5 also features high thermal conductivity and low thermal resistance, making heat dissipation easier and preventing it from overheating, thereby extending its lifespan. The intelligent control module 4 is mounted on the circuit board 3 to independently control the working states of the surface-mount LED 5 and the soldering iron tip 2. Therefore, the working state of the surface-mount LED 5 can be intelligently adjusted, such as adjusting brightness, maintaining standby mode, and providing fault alerts. Moreover, the working state of the surface-mount LED 5 is not affected by the working state of the soldering iron tip 2 and can be linked according to the working state of the soldering iron tip 2 or the usage status of the intelligent soldering iron.

[0051] The surface-mount LED 5 of this invention can be composed of multiple independent surface-mount LEDs installed at the first gap 12 between the port and the soldering iron core 2, or it can be a single LED installed at the first gap 12. Figure 8 In the second embodiment shown, the handle shell 1 is cylindrical, and its opening end 11 is also a circular cavity. The surface mount LED 5 in this embodiment is constructed as a circular piece whose outer contour can be inserted into the opening end 11. The corresponding outer contour can be circular, polygonal, or rectangular, etc. Furthermore, the surface mount LED 5 of the circular piece has an inner hole 50 in the middle to form an annular piece. The inner hole 50 allows the soldering iron tip 2 to pass through, and the lighting chips 51 on the surface mount LED 5 are spaced around and arranged on the surface of the annular piece facing the soldering iron tip 21.

[0052] The circuit board 3 of this invention can be placed only in the upper middle part of the inner cylinder of the handle shell 1, away from the opening end 11, and then electrically connected to the surface-mount LED 5 and the soldering iron core 2 via wires; or it can be as follows: Figure 6 In the embodiment shown, the circuit board 3 is constructed as a plate structure extending along the length of the inner cylinder of the handle housing 1, extending from a position away from the opening end 11 to a position close to the opening end 11. To prevent the circuit board 3 from rotating freely inside the handle housing 1, this embodiment has symmetrical slots 13 on both sides of the inner cylinder wall of the handle housing 1, into which the two sides of the circuit board 3 are inserted. A power interface 34 is provided at the end of the circuit board 3 away from the opening end 11. This power interface 34 can be a Type-C interface or a USB interface, etc., for connecting a power supply cable or charging the battery in the soldering iron. Since the circuit board 3 extends to the vicinity of the opening end 11, two connecting pins 31 can extend from the end of the circuit board 3 near the opening end 11. Two connecting holes 53 are provided on the surface-mount LED 5 of the annular plate, and the connecting pins 31 are inserted into the connecting holes 53 and fixedly connected to them. Figure 3 As shown, this allows the surface-mount LED 5 to be fixed to the end of the circuit board 3, and also enables electrical connection between the surface-mount LED 5 and the circuit board 3 via the connection pin 31, thus eliminating the need for wire connections. Since the surface-mount LED 5 is both fixed to and electrically connected to the circuit board 3, it no longer needs to be connected to the soldering iron tip 2, thereby reducing heat transfer from the soldering iron tip 2 to the surface-mount LED 5; furthermore, as... Figure 4 As shown, the inner hole 50 of the surface mount LED 5 in this embodiment is configured to allow the soldering iron core 2 to pass through and form a second gap 52 between it and the soldering iron core 2. Therefore, the surface mount LED 5 can be further away from the soldering iron core 2, further reducing the heat transfer from the soldering iron core 2 to the surface mount LED 5, so that the temperature of the surface mount LED 5 will not be too high.

[0053] Similarly, since circuit board 3 extends to the vicinity of the opening end 11, soldering iron tip 2 can be directly connected to circuit board 3, such as... Figure 5 In the embodiment shown, the circuit board 3 has a connection port 32 on the board body near the opening end 11. The connection port 32 directly penetrates to the end of the circuit board 3 where the connection pin 31 is located. A connector 33 is connected to the connection port 32. The soldering iron core 2 extends into the handle shell 1 and connects with the connector 33.

[0054] Since the surface-mount LEDs 5 or LED beads are quite bright, their illumination on the circuit board 3 can be dazzling. Therefore, to prevent glare, this invention also includes a diffuser 6, such as... Figure 2In the embodiment shown, the diffuser 6 is mounted at the opening end 11 and is closer to the soldering tip 21 than the surface-mount LED 5.

[0055] To better achieve independent control of the surface mount LED 5 and the soldering iron tip 2, in some embodiments, the intelligent control module 4 includes a lighting control unit and a soldering control unit. The lighting control unit is configured to intelligently control the brightness, start / stop, standby mode, automatic / manual operation, and fault alerts of the surface mount LED 5 via a button 8 on the handle housing 1. Specifically, a display screen 9 can be installed on the handle housing 1, and the method of lighting the surface mount LED 5 can be selected through the menu options on the display screen 9. For example, the surface mount LED 5 can be constantly lit after the soldering iron is powered on, or the soldering iron tip 2 can be switched on / off. 2. When heating is in operation, the surface-mount LED 5 is lit, and when the soldering iron tip 2 stops working, the surface-mount LED 5 is off, or normally closed (i.e., the surface-mount LED 5 is always off regardless of whether the soldering iron tip 2 is working or not); the brightness of the surface-mount LED 5 can also be adjusted to suit different working environments; the surface-mount LED 5 can also automatically turn off or display a breathing light state when the soldering iron tip 2 is stationary (when it is temporarily put down), and automatically turn on when working (when the soldering iron is lifted); it can even be designed to flash an alarm when the soldering iron malfunctions. Thus, the surface-mount LED 5 not only has a lighting function, but also a warning function and a power-saving function.

[0056] Because there is a certain distance between the surface-mount LED5 and the soldering iron tip 21, light will diffuse over this distance. Therefore, in order to better focus the light onto the soldering iron tip 21, such as... Figure 1 and Figure 8 In the first embodiment shown, the embodiment also includes a central focusing sleeve 7, which is connected to the opening end 11 of the handle shell 1. At least a portion of the focusing sleeve 7 extends from the surface-mount LED 5 toward the soldering tip 21 to form a focusing tube portion 70. The light emitted by the surface-mount LED 5 is focused by the focusing tube portion 70, so that it can more concentratedly illuminate the position of the soldering tip 21.

[0057] The patch LED 5 of this utility model can be located inside the opening 11 of the handle shell 1 or inside the focusing sleeve 7, depending on the actual design requirements. Since the patch LED 5 is connected and fixed to the circuit board 3, the position of the patch LED 5 can be adjusted by adjusting the length or position of the circuit board 3. Figure 7In the first embodiment shown, the surface-mount LED 5 is located inside the focusing sleeve 7. The focusing sleeve 7 includes a small-diameter end 71 with a focusing tube portion 70, a large-diameter end 72 for accommodating the surface-mount LED 5, and a connecting end 73 for connecting to the handle housing 1. The large-diameter end 72 is located between the small-diameter end 71 and the connecting end 73. The end of the circuit board 3 with the connecting pin 31 extends beyond the opening end 11, allowing the surface-mount LED 5 to be located inside the large-diameter end 72 of the focusing sleeve 7. The connecting end 73 can be connected to the handle housing 1 by a threaded connection, or it can be... Figure 8 As shown, a connecting sleeve 74 with external threads is fitted onto the connecting end 73, and the external threads of the connecting sleeve 74 are threaded into the open end 11 of the handle housing 1.

[0058] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0059] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
