Description
[technical field]
The present invention relates to a kind of hot melting fixture, particularly a kind of buffering and positioning mechanism of hot melting fixture.
[background technology]
Hot melting fixture generally is used for assembly production chain, is mainly used in the welding of hot melt five metals nut implantation plastic parts, hot melt etc., so that the assembling between the product.For example, the plastic shell of notebook computer need to be fixedly connected with by the metal nuts screw with mainboard, must adopt first hot melting fixture that the metal nuts hot melt is implanted in the plastic casing, make this metal nuts and plastic casing secure bond, and then by screw mainboard is secured on the plastic casing.Hot melting fixture mainly comprises cope match-plate pattern, hot molten column and lower bolster, when carrying out the metal nuts implantation of plastic parts, the plastic workpiece that at first will manually place nut is positioned on the lower bolster, then cope match-plate pattern moves downward, and drives preheated hot molten column and presses down the nut heating and be pressed on the plastic parts.
For making plastic workpiece registration in reflow process, need to one buffering and positioning mechanism be set at cope match-plate pattern, first plastic workpiece is pressed on the lower bolster in the process that cope match-plate pattern is moved downward, then hot molten column again contact product carry out hot melt.See also Fig. 1, it illustrates the structural representation of the buffering and positioning mechanism of prior art hot melting fixture, this hot melting fixture comprises a cope match-plate pattern 10 and a lower bolster 20, this buffering and positioning mechanism mainly comprises a cylindrical positioning guide column 11 and a spring 12, the upper end of this positioning guide column 11 is fixed on the cope match-plate pattern 10 of this hot melting fixture, this spring 12 is sheathed on this positioning guide column 11, and its upper end connects this cope match-plate pattern 11, and it is horn-like that the lower end is.During production, on this lower bolster 20 that product 30 is positioned over, this cope match-plate pattern 10 moves downward, horn-like lower end 13 contact products 30 of this spring 12, and then this spring 12 is compressed, and product 30 is applied compaction pressure in advance, makes its registration.This spring 12 length after compressed avoided this positioning guide column bump product to cause product bad when positioning guide column 11 length of this buffer gear finished less than hot melt.
The buffering and positioning mechanism of prior art hot melting fixture, mainly have following defective: the lower end of (1) this spring height is different and be that line contacts with product, when compressing product surface, product surface produces easily impression or weighs product wounded because of unbalance stress, and the spring lower end also can't be applicable to the non-planar surfaces of various shapes; When (2) compressing product, the spring contraction posterior end does not have the guide pillar restriction to be prone to bending or displacement, and the spring fatiguability damages, and needs often to change; (3) spring only connects cope match-plate pattern by the upper end, comes off easily in the production.
[summary of the invention]
In view of this, the object of the invention is to overcome the deficiencies in the prior art and defective, a kind of product surface that is applicable to various shapes is provided, can not weigh product wounded, stable and life-span of serviceability is the buffering and positioning mechanism of long hot melting fixture.

One movable slider, it can be arranged on this positioning guide column up and downly, and its lower surface contacts when hot melt and cooperates and the compression product surface; And
One flexible member, it is sheathed on the main body of this positioning guide column, and is connected between this cope match-plate pattern and this movable slider.
Preferably, this movable slider is the hollow circuit cylinder body structure, its upper end is provided with a through hole, its inside is provided with a diameter greater than the cylindrical activity space of this through hole, this through hole is passed in the main body upper end of this positioning guide column, and the step-like structure of this positioning guide column is up and down at the cylindrical activity space of this movable slider.
Preferably, the step-like structure of this positioning guide column is the inverted T shape step-like structure.
Preferably, this movable slider is that fire resistant resin materials processing forms.More preferably, this movable slider is that epoxy resin or acetal resin (POM) process.
Preferably, profiling cooperation, stress equalization when making the compacted location of product are processed into according to the shape of product surface in the lower surface of this movable slider.
Preferably, this flexible member is a spring.
Compared to prior art, the buffering and positioning mechanism of hot melting fixture of the present invention has the following advantages: 1, the lower surface by movable slider is that face contacts with product surface, and stress equalization when compressing product has been avoided the generation of impression; 2, spring integral body is done elastic deformation in the direction of positioning guide column restriction, displacement or distortion can not occur, and serviceability is stable; 3, there are movable slider restriction, difficult drop-off in the spring lower end; 4, the profiling cooperation can be made according to difform product surface in the lower surface of movable slider, and the scope of application is wider; 5, movable slider is that resin material is made, and hardness is less, is difficult for weighing wounded product.
