2) Sintering rough material process:

3.1) Processing the front and back of the welding head

4.1) Processing the left and right façade of the welding head

4.2) Processing the tangential knives in the right façade of the welding head

5, grinding welding tip and tangential cutter tip process

As an improvement of the present invention, The parallel electrode horn with a tangential cutter includes a horn main body portion and a welding head extending from the horn main body portion, the welding head portion including a welding portion and a tangential cutter portion, the welding portion and the tangential cutter The portions extend to form a welding tip and a tangential cutter tip, respectively. The mechanical equipment for preparing the welding head main body portion, the welding head portion, the welding portion and the tangential cutting portion are all processed by a wire cutting machine.

As an improvement of the present invention, In step 3.1), the welding head is cut 8 mm away from the distal end of the welding head to form the front façade of the welding head, and about 1 mm after cutting the end surface of the distal end of the welding head, with a certain The slope is cut along the body of the horn to form a weld tip of the post-face and the plane of the weld head.

In steps 4.1 and 4.1), the welding head is cut at a certain inclination from the distal end of the welding head to form the left and right façades of the welding head, and after cutting to the end surface of the distal end of the welding head Approximately 1 mm is retained, and the left and right façades of the weld head and the planar weld tips are cut along the body of the horn at a certain slope.

Preferably, the metal material of the tangential blade portion is made of a tungsten metal material or a tungsten alloy material.

Compared with the prior art, the parallel electrode welding head with a tangential cutter of the present invention has at least the following beneficial technical effects.

First of all, the parallel electrode welding head is mainly used in the manufacture of various electronic components for the welding of small enameled wire or metal wire lead-out joints. The enameled wire lead wire is both thin and short, the wire diameter is generally below 0.10mm, and the length is only about 20mm. The pad is also very narrow, generally only about 1.0×1.0mm. It is not easy to cut the thin and short enameled wire tails in such a small space after the welding is completed. If you accidentally damage the solder joints. In order to destroy the workpiece, it is necessary to carefully cut it under the microscope with scissors or a knives, and quality problems such as the length of the fracture are inevitable, and the present invention organically integrates the tangential cutter tip and the welding tip into the same parallel electrode horn, and the welding and The removal of the enameled wire tail is completed synchronously, which not only makes the tangential line very easy, but also has a uniform tangential fracture, which obviously improves the work efficiency and product quality.

Secondly, in the prior art, the tip end portion of the welding head of the parallel electrode welding head is processed into a certain inclination, and the tail of the enameled wire after welding is cut by the inclination, but the effect is not good because the end surface of the tip of the welding head cannot be Press evenly on the weldment. The parallel electrode welding head is welded by electric resistance welding. The electric resistance welding is also called pressure welding. If the welding head end surface of the parallel electrode welding head cannot uniformly press the welding pressure on the welding piece, the welding will be affected by the difference of the electric resistance value. quality. The end face of the welding tip of the parallel electrode welding head with the tangential cutter has a flat structure, and can uniformly press the welding pressure on the welding member, so that the welding quality is reliable.

Thirdly, the present invention is provided with a separating small groove between the welding tip and the tip of the tangential cutter. The function of the separating small groove is to effectively reduce the high temperature generated by the welding tip during welding and the conduction of the tangential cutter, and avoid the tip of the tangential cutter. It softens at high temperatures and affects its tangential effect. Secondly, it can effectively eliminate the welding residue generated during welding of the welding tip, because the plane of the tip of the tangential cutter is slightly higher than the plane of the welding tip. If the separation groove is not provided, when welding The resulting weld residue accumulates between the tip of the tangential cutter and the tip of the weld, which in turn affects weld quality and tangent.

Fourthly, the material of the tangential cutter of the invention is selected from tungsten metal or tungsten alloy. The tungsten is the highest hardness among all metal materials, and the tungsten has the characteristics of high temperature resistance and no adhesion to other materials. The tangential cutter is made of tungsten, and the blade edge is very hard and sharp. It is fully capable of cutting the tail end of the enameled wire copper core which is softened by high temperature, and has the advantage of cutting tens of thousands of times without grinding and cleaning the blade.

In addition, the tangential knives of the present invention are mounted on the tip of the horn which produces a high temperature of more than 1000oC during welding. On a parallel electrode horn having a diameter of only about ¢3.0, the space of the tapered horn is smaller, and the present invention can The welding head is provided with the welding part, the tangential cutting part, the welding tip, the tangential cutting edge and the separating small groove. The structure is very clever and compact. The preparation is completed on the online cutting machine. The processing equipment is relatively simple and common, and the processing method is novel. Simple and unique.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the invention

The present invention will be further described in detail below in conjunction with the drawings and specific embodiments. The specific embodiments described in the specification are to be construed as illustrative only and not limiting.

First of all, it is necessary to clarify the concept of "parallel electrode welding head": the welding metal respectively connected to the positive and negative electrodes of the welding power source is referred to as two electrodes; the two electrodes are placed on the same side of the welding element as parallel electrodes; The electrodes are integrally joined together as a parallel electrode horn.

The structure of the prior art parallel electrode horn includes a horn body portion, a welding head portion, and a horn tip portion. The parallel electrode welding head adopts two electrodes which are processed into symmetry by the high temperature resistant electrode material, and the two electrodes are connected together by the heat curing adhesive to serve as the intermediate spacer layer of the two electrode insulations. The parallel electrode welding head is formed; the upper half of the parallel electrode welding head is connected with the welding head clamp, which is called the welding head main body portion; the intermediate spacing layer of the parallel electrode welding head is the central axis, and the parallel electrode welding head can be divided For the front, rear, left and right four façades, the lower half of the parallel electrode horn is extended to form a tapered cube with a certain inclination, and the four sides of the front, the rear, the left and the right are respectively formed into a tapered cube. The tapered cube in the lower part of the welding head is called the welding head; the farthest end of the tapered cubic welding head is called the tip end of the welding head.

For convenience of description, the present specification differs from the connection of the two electrode tips at the tip end of the horn, and the prestressed electrode horn, the ohmic contact parallel electrode horn, and the ohmic contact parallel electrode horn in the parallel electrode horn of the directly solderable enamel wire mentioned in the background art. The tip contact parallel electrode welding head is summarized and referred to as a welding tip contact parallel electrode welding head, and the parallel electrode welding head of the tip end of the two electrodes is referred to as a welding tip connected parallel electrode welding head, and The tips of the electrodes are neither contact nor connected, but parallel electrode horns that are insulated from each other are referred to as solder tip insulated parallel electrode horns.

After clarifying the basic structure of the prior art parallel electrode welding head, the parallel electrode welding head with the tangential cutter of the present invention can be divided into three types: A type, B type and C type because of the different welding tip structure: Type A For the welding of tip-connected parallel electrode horns with tangential cutters, type B is a parallel electrode horn with a welding tip contact tangential cutter, and type C is a parallel electrode horn with a welded tip insulated tangential knives. It is to be noted that the present invention includes a parallel type electrode horn with a tangential cutter of type A or B or C. Regardless of the electrode material of the main body of the horn, the metal material of the tangential blade is preferably made of tungsten metal or tungsten. Alloy material, tungsten is the highest hardness of all metals and has the characteristics of high temperature resistance and no adhesion to other materials. The invention adopts the method as a tangential cutter, and the blade is very hard and sharp, and is fully capable of cutting tens of thousands of enameled wires which are softened by high temperature during welding. The end of the copper core does not stick and the tip of the tangential cutter remains sharp and cleansed throughout its service life.

The structure of the parallel electrode horn with a tangential cutter of the present invention will now be described with reference to the accompanying drawings.

It should be noted that the embodiment is a parallel electrode horn with a type A welding tip and a tangential cutter as an embodiment. The structure of the A-type embodiment is clarified, and the B-type welding tip contact strip tangential is also clarified. The parallel electrode horn of the knives and the parallel electrode horn of the C-type welding tip insulated tangential knives are omitted, so the structure of the parallel electrode horns of the B-type and C-type tangential knives will not be described again.

The end surface of the soldering tip is a planar structure, and the end surface of the soldering tip is perpendicularly arranged with the longitudinal direction of the parallel electrode soldering tip. That is, it is preferable that the end surface is at an angle of 90 degrees with the axis of the extending direction of the tangential blade portion 105. The tangential cutter portion 105 is extended to form a tangential cutter tip 105A, and a small slit 107 is formed between the welding tip 104A and the tip end of the tangential cutter tip 105A.
