Description

Fixture revolution and the clamping device of automatic tin dipping machine

Technical field

The utility model belongs to the electronic product manufacture and uses the equipment technology field, is specifically related to a kind of fixture revolution and clamping device of automatic tin dipping machine, for the fixture of the wire that clamping had to use for electronic products, under clamp position, turns round, and meets the tin sticky requirement to the wire two ends.

Background technology

Above mentioned electronic product mainly refers to but is not restricted to refer to laptop computer and mobile phone, and due to this electronic product small volume, the volume of connector is also corresponding less, so the wire connected between connector and circuit board is very very thin.In automatic assembly line is produced, usually the two ends of one group of wire are arranged and be positioned on adhesive tape by last station, particularly, to with parallel mode, stick on adhesive tape according to the end of the wire that needs quantity, and maintain rational spacing distance between adjacent wires, then by next station, outer being moved (" edge of a knife heating lead is outer by moving device " that specifically can announce referring to Chinese invention patent Granted publication CN102130410B) implemented in the end of wire, again then to through the outer core by the wire after moving, revealing the tin sticky of naked position, excise or wipe out the adhesive tape of moving and be positioned at wire end after tin sticky, by the end of the wire of one group of tin sticky and connector, be finally the conductive connecting pin welding on electric connector, can supply with by this aforementioned laptop computer or mobile phone production firm uses.

Technical information about automatic tin dipping machine can be seen in disclosed Chinese patent literature, " the automatic tin dipping device " that " tin-soaking processing device " that " automatic tin dipping machine ", the CN202015889U disclosed " a kind of new type auto solder machine " slightly provided with " electric wire tin sticking processor ", the CN202015888U that recommend as CN2562913Y exemplified, CN102151931A disclose and CN102601482A introduce, etc.

although being not limited to above-named patent scheme all has and replaces manual tin sticky and use and alleviate workman's operation intensity, improve the strong point of tin sticky efficiency and quality assurance, but how all not provide the enlightenment that is tending towards the end tin sticky simultaneously of the very micro-wire of spacing between that high density state is arranged and adjacent wires to a group, especially, after one group of wire is arranged with parallel mode and located, clamping is to fixture, while again fixture being fixed on solder machine to tin sticky, because the gap between adjacent wires is minimum, therefore when tin sticky, tin adhesion situation often appears in the gap between adjacent wires, if can not reject in time i.e. comb before tin liquor is solidified removes, so certainly can cause short circuit.Again owing to needing under normal conditions the two ends to one group of wire to carry out tin sticky, specifically, after the end tin sticky completed one group of wire, during again to the other end tin sticky of one group of wire, fixture need be rotated to 180 ° clamping under the state of wire, if therefore can not guarantee fixture Rotate 180 °, must clamp for the second time so, so-called clamping for the second time is that one group of wire is unloaded from fixture, more again clamps on fixture after turning over 180 °.So mode of operation has not only increased operator's manipulation strength, and affects tin sticky efficiency.And, after fixture is positioned on fixture together with wire, if can not reliably clamp fixture, exist so fixture to come off and integral body enters in solder pot (also can claim molten Xi Chi) from solder machine together with wire, not only cause wire to be scrapped, and undermine fixture, exist in addition because of tin liquor and splash and pollute and even injure operator's anxiety.

Be not limited to the above-mentioned problem exemplified and all do not provide referential technology enlightenment in current published patent and non-patent literature.The applicant has done lasting and useful design for this reason, and technical scheme described below produces under this background.
