Abstract
The utility model relates to a welding head for an electronic spot welding machine which is used in electronic industries and microelectron industries. The welding head for an electronic spot welding machine is composed of two parallel electrodes which are made of high-temperature resisting metal materials and combined together. The end parts of the two parallel electrodes are in mutual ohmic contact. The rest parts of the two parallel electrodes are insulated and separated. The utility model has the functions of insulating varnish removing, welding, line cutting, etc. The utility model has the advantages of simple structure, good welding quality and high work efficiency.
Description
The utility model relates to the soldering tip parts of the electronic spot welder of a kind of electronics industry, microelectronic industry.
Electronics point electric welding welding is that a large amount of electric currents passes through two soldered metallic objects in moment, and electric energy converts heat energy to, produces the welding processes of fusion at these two metallic objects.If soldered metal surface has insulating barrier to have (as enamelled wire), electric current can not pass through metallic object, then puts the electric welding welding and just can't carry out.In electronics industry, microelectronics industry, often need the welding fine enamelled wire, at first just must remove the insulating barrier on the enamelled wire.Can imagine that remove insulating varnish resembling on the silky enamelled wire of hair, how cumbersome technology is, complicated.Accomplish like this, just must can save except that lacquer craftwork when making welding, improve the operating efficiency of electric spot-welding machine the critical component of spot welding machine---soldering tip improves.
The purpose of this utility model provides a kind of point welding machine welding head, and this soldering tip can directly carry out an electric welding welding on fine enamelled wire, to improve the efficient and the quality of welding.
To achieve these goals, two electrodes that this point welding machine welding head is made by refractory metal material, that lump together constitute, it is characterized in that the mutual ohmic contact of end portion of two parallel poles, contact resistance is generally≤200m Ω, and remainder is separated by the insulating barrier insulation.The insulation viscose glue that has one deck to be adhesively fixed and insulate and separate between two parallel poles.In order to adapt to the needs that weld various materials, the terminal end shape of soldering tip can be made plane, face of cylinder type, plagiohedral, V-shape or taper structure.
During the energising welding, welding pressure reaches set point on the soldering tip when being added in, could trigger main frame, main frame provides the pulse current that configures, and electric current makes most advanced and sophisticated heating at first by having the soldering tip tip of certain resistance, the insulating varnish of molten coating removal envelope curve, because the effect of welding pressure, electric current continues by wire under the insulating varnish and metal substrate, produces the melting welding welding of some electric welding.Owing to saved manual paint removal operation, operating efficiency improves greatly.
The utility model is described in further detail below in conjunction with accompanying drawing.
But Fig. 1 is the vertical section structure figure of the point welding machine welding head of paint removal.
But Fig. 2 is the end portion vertical section structure figure of the point welding machine welding head of paint removal.
Among Fig. 1,1 is two parallel poles of soldering tip, adopts the refractory metal material manufacturing, as metal materials such as tungsten, molybdenums.2 is insulating barrier, can adopt the insulation viscose glue advance to paste, also insulating material such as available mica sheet.3 is the soldering tip end portion, and two electrodes are ohmic contact each other endways, and contact resistance is generally≤200m Ω, and remainder is separated by the insulating barrier insulation.
Among Fig. 2, (a) be the soldering tip of planarized structure for terminal end shape, (b) be the soldering tip of cylinder surface structure for terminal end shape, (c) be the soldering tip of plagiohedral structure for terminal end shape, (d) be the soldering tip of V-shape structure for terminal end shape, (e) be the soldering tip of taper structure for terminal end shape, other 3 is the soldering tip end portion.
Claims (3)
- But 1. the point welding machine welding head of a paint removal, two parallel poles being made by refractory metal material, lump together are formed, and it is characterized in that the mutual ohmic contact of end portion of two parallel poles, and remainder is separated by the insulating barrier insulation.
- 2. a point welding machine welding head as claimed in claim 1 is characterized in that having one deck to be adhesively fixed between two parallel poles and the insulation viscose glue of the separation of insulating.
- 3. one kind as claim 1,2 described point welding machine welding heads, it is characterized in that the terminal end shape of soldering tip is plane, face of cylinder type, plagiohedral, V-shape or taper structure.
