Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a soldering iron tip, and more particularly to a soldering iron tip which can be coated with a molten electrode during a soldering operation. [Prior Art] In the field of electronic production, the soldering iron is widely used in the welding of various electronic components. Generally, the composition of the soldering iron mainly includes a grip, a casing and a tip. The two ends of the housing are respectively connected with the handle and the soldering iron head, and the electric wires are arranged at the other end of the handle relative to the housing, and the ribs are connected to the heating device to provide the energy to the housing by the transposition. Inside the line _ electrical energy is converted into heat. After that, the heat is further transferred to the tip to raise the temperature of the tip to the temperature of the smelable electrode (such as copper, tin, silver, etc.) to facilitate the soldering of the electronic components. & In order to make the welding work smoothly, in the structure setting of the soldering iron tip, y is designed to be in contact with the soldering-end design, the tip-shaped heating end, the heating end in the word, or the chamfering blade type. Heating end, in order to meet the needs of different welding positions. For example, although the welding line between the connecting circuit and the electronic components on the circuit board is better than that of the temple, the soldering iron with a pointed tapered heating end is used for the bright spot. Soldering; or 'When the range is wider, the solder joint is soldered to the solder joint with a flat heating end or a beveled blade type heating end. ‘, , , , J, in the operation of the welding operation, are first contact with the solder joints, pre-,, and fresh spots. Then one end of the metal electrode is inserted into the gap between the solder joint and the soldering iron tip in the 201117911 gap and is in contact with the tip of the tip of the soldering iron tip, the letter type or the oblique σ blade type heating end, and the metal is melted by the soldering iron head. The welding rod is used to make the metal welding rod-shaped solder in the molten state, and the solder is welded to the soldering point to complete the welding operation. In this process, since the position of the head contacting the metal welding rod is exposed to the external environment, it is easily exposed to the outside space. The loss of heat caused by the convection side causes the soldering iron to heat the metal electrode unevenly, which affects the welding quality and hinders the welding operation. In addition, the structural design of the conventional soldering iron tip does not limit the flow direction of the molten solder. When the metal electrode is heated by the soldering iron (4), it will diffuse on the solder joints to flow to other areas on the board adjacent to the fresh spot or adjacent to the solder joints, resulting in wiring on the board. Damage or short circuit caused by other electronic components being contaminated with solder. Therefore, the conventional tip is made, it is easy to make the circuit board or the electronic components adjacent to the fresh spot suffer from the fact that the operator's technology is not sophisticated or financially negligent. I, the board is in the process of correction (4) 1 risk. " In view of the lack of conventional soldering iron tips, it is necessary to improve the structure of the soldering iron tip to improve the working efficiency and ensure the welding quality of the sub-components and reduce the risk of heavy work and maintenance. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a soldering iron tip, which can be used to improve the conventional solder joints. When the contact surface between the soldering iron tip and the metal electrode is exposed to air, it is easy to cause heat loss and affect the soldering. Quality issues. And the metal electrode _ _ _ heating 镰 after the _ _ solder material spread to the fresh spot to the area outside the 201117911 or short circuit problem. 'Causes _ and adjacent electronic components that are adjacent to the solder joint to be damaged by solder contamination

The soldering iron through hole is opened in the radial direction of the soldering iron tip and communicated with the soldering operation, and the guiding hole and the workpiece # are in a position overlapping each other. The electrode is heated and melted through the through hole, so that the molten electrode flows along the channel from the channel to the workpiece. According to another aspect of the invention, a soldering iron tip is used for heating a welding rod to perform a welding operation on a workpiece, wherein one end surface of the soldering iron head has a guiding hole, and the hole/mouth is opened in the axial direction of the soldering iron head. And forming a channel in the soldering iron tip, and the channel is exposed on one side of the soldering iron head. During the welding operation, the relative position of the diversion hole and the workpiece is mutually weighted, and the revolving strip is heated and melted in the passage channel, so that the molten electrode flows along the passage from the guide hole to the workpiece. The soldering iron tip disclosed by the invention is arranged by the communication of the flow guiding hole and the passage, so that the molten welding rod is restricted to the workpiece by the limiting action of the passage, and the molten welding rod can be prevented from flowing due to its own diffusion. Other areas outside the workpiece. At the same time, during the operation of the welding operation, since the electrode is covered in the channel at one end of the soldering iron tip, the molten electrode can be maintained in a stable high temperature environment by the covering action of the channel, which can be avoided. The molten electrode directly contacts the outside air to cause a problem of uneven heating. 201117911 Further explanation. [Embodiment]

The electric soldering iron 1 includes a grip in addition to the soldering iron head 10. Handle 2G and metal case 3G. The handle 2 has an electric wire 210. The other end of the grip 2G is connected to the metal casing 3Q. The electric wire (10) is connected to a heating device (not shown) for transmitting the electric energy provided by the processing to the metal casing 3G. The metal casing is provided with a plurality of heat dissipation holes 31 (), and a plurality of coils (not shown) are accommodated in the metal casing 3A for converting electrical energy transmitted to the metal casing 30 into heat energy. . One end of the tip 10 is bored in the metal casing 30, and the tip 1 has a side surface 110. The side surface 110 extends from one end of the metal shell 30 to the other end of the opposite metal body 30. Further, the soldering iron tip 1 has a & face 120, and the side surface 110 of the soldering iron head 10 surrounds the edge of the end surface. That is, the side surface 110 and the end surface 120 are substantially perpendicular to each other. The end surface 120 has a flow guiding hole 121, and the flow guiding hole 121 is opened to the end surface 12A along the axial direction of the soldering iron head 10. The axial direction guide orifice 121 extends from the end face 12 of the tip iq toward the tip end of the tip 1 of the metal housing 3 and extends at the other end of the tip 31 opposite the metal housing 30. A channel 122 is formed. 201117911 In addition, the side 110 of the tip ίο has a through hole (1). therefore. The through hole (1) is formed at an appropriate position of the side surface 110 adjacent to the end surface 120, and the through hole ηι is opened to the side surface 110 in the radial direction of the cymbal 10. This radial direction means that the through hole ιη 延伸 extends from the side surface 11G toward the passage 122 and penetrates the side surface 11G, so that the through hole 111 communicates with the passage 122. And, the side surface 110 is formed adjacent to one side of the through hole (1) to form a leading inclined surface 112. The guide slope 112 is inclined from the side of the side surface (10) adjacent to one side of the through hole 111 toward the end surface 120. Please also refer to "Fig. 1" to "3B".

The range covered by the orifice 121 of the end face 12 is included in the entire workpiece 410, or the workpiece 41 is immersed in the passage 122 of the tip 10 (not shown). After that, the metal electrode 201117911 5〇 (such as tin wire, copper welding scale) is extended from the through hole m of the soldering iron (4) into the channel m. At this time, the welding (4) can be formed by the conduction/inlet passage of the slanting surface ιΐ2 of the _1G, and the welding material (not shown) of the heating side of the welding rod 5G. The electrode 5, which is disposed in the channel 122, is covered by the tip (4). Therefore, after the field electrode 5 is formed into the solder of the county, it is covered and blocked by the carcass (7) and is confined to the channel 122. And flowing along the channel 122 from the flow guiding hole 121 to the workpiece 41G, and the solder in the state of the molten state flows to other regions on the substrate 40 adjacent to the workpiece 410. Further, as shown in "Fig. 6" and "Fig. 7", in the second embodiment, the end face 120 of the tip 1 can also be obliquely disposed on the ram head 10, that is, the end face 120 / side The relationship between 110 is greater than or less than 90 degrees, and not perpendicular to each other. Therefore, the electrode 50 can be inserted into the passage 122 via the through hole ηι or the flow guiding hole 121. And 'after the electrode 5 is formed into a molten state of solder, it is also covered and blocked by the winding and is confined to the workpiece (10) within the range covered by the channel η2' to further prevent the molten solder from flowing to The area other than the workpiece willow. Referring to "Fig. 8" and "Fig. 9", the tip 10 of the third embodiment of the present invention is applied to a hot clip type soldering iron 6. The hot clip type soldering iron 6 has two grips 610, 610', two metal housings 620, 620, two soldering iron tips 1, 630 and a pivot 640. One of the two ends of the metal casing 620 is respectively connected to one of the handles 61 〇 and the tip 1 本 disclosed in the second embodiment of the present invention, and the other metal casing 62 〇, the two ends of the 2011 17911 are respectively The handle (four) and a slanted blade type (or - type) pavement _ are connected. Wherein, the two grips 610, 610 are connected by a pivot 64 , so that the two grips 61 〇 , 610 ′ can pivot relative to each other to pivot and drive the two iron tips 1 〇 and ( 4 ) to close together or Phase separation. It can be understood that the third embodiment of the present invention, the setting of the two soldering iron heads can include but not only the invention of the third real _ the county's soldering iron head 1 〇 and the general oblique mouth blade type (or - word Type) soldering iron head (four) to do the match. Therefore, in the third embodiment of the present invention, the two soldering iron tips disposed on the hot clip type soldering iron may be provided in the form of the soldering iron tip 1 disclosed in the third embodiment of the present invention. In this embodiment, the combination of the soldering iron tip 1 disclosed in the second embodiment of the present invention and the general oblique blade-type (or sub-type) soldering iron tip 630 is exemplified, but not limited thereto. . One end of the soldering iron tip 1 disclosed in the second embodiment of the present invention is disposed in the metal casing 620, and the soldering iron tip 1 has a side surface 11〇. The side surface 11 is attached to the other end of the metal housing 620 from one end of the metal housing 620. At the same time, the tip end of the tip 10 opposite the metal housing 620 has an end face 12〇, and the side surface 110 of the head 10 surrounds the edge of the end face 120, so that the side 11〇 and the end face 12〇 are substantially perpendicular to each other. The connection relationship is formed, and a cutting plane 113 connecting the end faces 120 is formed at a position adjacent to the end face 120. The end surface 120 has a flow guiding hole 121, and the flow guiding hole 121 is opened to the end surface 120 along the axial direction of the soldering iron head 10. The axial direction guides the flow hole 121 from the end face 12 of the soldering iron head 10 toward the tip end of the metal shell 62 from the tip end of the soldering iron tip 10, and is formed at the other end of the soldering iron tip 1 opposite the metal housing 620. One dew 11 201117911 is for the passage 122 of the plane 113. Please refer to "8th" to "1st drawing" at the same time. When the hot clip type soldering iron 6 disclosed in the third embodiment is used for welding work, the slanted blade type (or - type) tip 630 is used. Abutting the turn-side, the crown 1() is then brought closer to the other side of the workpiece relative to the oblique-blade (or-shaped) tip 63. At this time, the relative positions of the guide holes 121 of the tip 1 and the workpiece 410 overlap each other, and the side of the workpiece 4 (ie, the position to be welded) is not immersed in the passage (2) of the tip 1 ( After "Q", a metal electrode 5 (such as a tin wire, a steel electrode, etc.) is inserted into the passage 122 from the gap between the two tips 10, 630. Wherein, since the gap between the two soldering iron tips 10, 630 and the passage 122 are used for the one end of the welding rod 5 to be inserted and accommodated therein, the width dimension of the gap and the passage 122 needs to be at least slightly larger than the diameter of the welding rod 50. size. After the electrode 50 is passed through the channel 122, the electrode 5 is placed at one end of the channel 122 by the heating action of the tip 10 to form a molten solder (not shown). The molten solder is shielded from the channel 122 and flows along the channel 122 and the flow holes 121 to the workpiece to complete the soldering. In addition to the circular arc-shaped structure, the structure of the channel 122 of the winding head 10 may be such that the channel 122 is formed in a V-shaped (or triangular) structure as shown in Fig. Similarly, the molten solder can be blocked from being restricted to the inside of the passage 122, and the molten solder can be prevented from flowing freely on the workpiece 410. Since the electrode 50 is heated and melted in the passage 122 of the tip 1 and the molten solder formed by the electrode 50 is coated in the passage 122. Therefore, there may be 12 201117911 = welding (4) in the heat transfer due to the heat loss too fast and: T welding (four) Na into the wheel from the heating zone, thereby reducing the risk of soldering and reworked several risks or substrates to the solder The risk of contamination and damage.
