Description

The electronic component tin soldering equipment

The utility model is relevant a kind of electronic component tin soldering equipment, refers to especially a kind of electronic component is placed on the pivotable rotating disk, can process operation.

Generally speaking, most of electronic components have a pin usually at least, and pin can be inserted on the circuit board electronic component and can be by solid welding, before electronic component fixedly is welded in circuit board whereby.Also can impose scolding tin at pin and handle, one can prevent that the pin that machines the back electronic component from continuing oxidation and producing impurity in the surface, simultaneously, can increase pin when solid welding and the conductivity of the tackness of other scolders and pin; Consult Fig. 1, in general electronic component scolding tin flow process chart roughly needs through the following step:

First step, depainting: the enamel-cover layer on the pin of electronic component is removed.

Second step is coated with soldering flux applying: be coated with soldering flux applying on the pin after removing the enamel-cover layer.

Third step, preheating: improve and to be stained with the temperature of covering pin behind the scaling powder, cover in order to being stained with of scolder.

The 4th step, scolder is stained with in spray: the scolder that heat is melted is coated on the described pin.

The 5th step is coated with soldering flux applying: be coated with soldering flux applying on the pin of scolder once again being covered with.

The 6th step, iron flat: the tin on the pin is prominent, scruff etc. irons to after smooth finishes.

And early stage dealer is in order to finish above-mentioned scolding tin step, most electronic components are inserted in one to have on the tool of predetermined area, cooperate this tool again and most processing assemblies are set, make described processing assembly with the lot lot progressively the mode of operation in regular turn (step by step) the most electronic components on the tool are processed, yet this kind operation and single unit system thereof but have the following difficult desirable part that claims:

One, owing to must supply most electronic component settings simultaneously on the described tool, therefore, it is quite high that the precision of this tool requires, relative increase the cost of manufacturing tool, this is a unfavorable industry development part.

Two, these processing assemblies add man-hour to the electronic component on the tool, it is the pattern that adopts straight line in the plane and batch (-type) to carry out, this pattern makes the configuration of processing assembly and relevant device numerous and diverse relatively, and make the processing operation can't obtain preferable production efficiency, if think further to add automation equipment, its required cost is quite high, and this also is a desirable not to the utmost part.

But the electronic component tin soldering equipment that provides a kind of continuous and automatic, simplified equipment and efficient high is provided the purpose of this utility model.

The utility model is a kind of electronic component tin soldering equipment, be used for processing electronic component, it is characterized in that: assembling one pivotable rotating disk on the board, the rotating disk circumferential position fixedly installs most tools that are used for for described electronic component inlay card location of arranging in the form of a ring with the rotating disk pivot, and circular row is adjacent to around the rotating disk in regular turn, reach the most processing assemblies that are fixed on the board of assembling on the path that rotates of these tools, and around being adjacent to rotating disk and on the path that rotates of these tools, in the assembling one the tin stove that heat is melted the tin material being housed, this tin stove also is to be fixed on the board.

So electronic component tin soldering equipment 1 of the present utility model has the following advantages and effect:

One, this tin soldering equipment 1 is to utilize helicoid rotating disk 3 to cooperate each processing assembly to finish whole work flow, not only makes integral device more simplify the demand that also reduces the space.

When two, helicoid rotating disk 3 operates, can process continuously, for promoting greatly on the production efficiency, more can cooperate automation equipment to finish consistentization production operation, its required cost is far below installed required expending in the past.
