Description
Technical field
The utility model relates to Wave soldering fixture technical field, particularly a kind of frock for wave soldering wiring board.
Background technology
Along with electronic product development in pluralism, mount technology is progress constantly, and pursuit paster high accuracy and high efficiency become inexorable trend.At present when SMT produces, first pcb board is fixed on tool, drives tool successively through each station of SMT line body by guide rail.If the problems such as paste solder printing offsets, the skew of surface mount elements that pcb board location will definitely not brought, thus affect the production quality of pcb board.Because pcb board is glass fibre material, itself easily produces distortion, adopts pin location to be difficult to the upper surface of the complete joint tool in plate face ensureing pcb board, thus easily produces the skew of SMD components when paster operation, even produce material casting phenomenon, bring hidden danger to quality.Along with the enhancing of people to environmental protection consciousness has had new welding procedure.Before wave-soldering is adopt leypewter, but lead is heavy metal has very large injury to human body.So there has been now the generation of lead-free process.It has employed SAC and special scaling powder and the higher preheat temperature of the requirement of welding jointing temp, if in order to prevent thermal shock from having ICT can have impact to detection on the other hand.From technological angle, wave soldering machines can only provide seldom a bit the most basic equipment operational factor adjustment, and may affect to circuit board in welding process.Especially part Sensitive Apparatus, once be heated in wave-soldering process too much, may cause device damaged, finally cause damage of product or reduce useful life.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, provides a kind of compact conformation, the easy to operate frock for wave soldering wiring board.
For achieving the above object, the utility model is by the following technical solutions:
A kind of frock for wave soldering wiring board described in the utility model, comprise left plate arranged in parallel and right plate, the two ends of left plate and right plate are respectively equipped with interconnective fixed heads with both, protective plate is provided with between left plate and right plate, the inboard face of right plate above protective plate is provided with draw-in groove, and left plate is provided with some reference columns coordinated with draw-in groove.
Further, the inboard face of described left plate and right plate is equipped with chute, and chute is located at below draw-in groove, the dual-side of protective plate is connected in the chute on left plate and right plate respectively.
Further, described reference column has the eccentric orfice running through left plate, in eccentric orfice, be equipped with rotating alignment pin.
Further, described alignment pin upper end is provided with hemispheric buckle, and the lower end of alignment pin is provided with base plate, is provided with spring between base plate and left plate bottom surface.
Further, described protective plate is provided with some welding holes coordinated with welding circuit board point.
The utility model beneficial effect is: the utility model is rational in infrastructure, and left side plate is accurately located circuit board by draw-in groove and reference column, and the alignment pin on reference column makes circuit board be fixed on reference column by buckle, quick and easy for installation; Left side plate coordinates with crest welder slide rail thus reduces the impact of thermal shock on circuit board by protective plate.
