Description
Technical field
Circuit board dividing technology is the utility model is related to, more particularly to a kind of positioning tool and semi-automatic board separating device.
Background technology
The circuit board of SMT (Surface Mount Technology, surface mounting technology) industry usually uses connecting plate side
Formula, this measure be in order to improve controller assembling before production efficiency, thus, when circuit board complete burning program, start single control
Before the assembly working of device processed, connecting plate need to be divided into veneer form to carry out subsequent handling, and split more connecting plate splicing circuit boards
Method is roughly divided into two classes：Milling machine and board separator.And be mostly two jigsaw modes for current body electronics controller circuit board, if
Cut using milling machine, although its precision is high, high is required to the accuracy of manufacture of cutting tool, cutting beat length, so that raw
It is high to produce cost, and production efficiency is low.
And although board separator cutting accuracy is not so good as milling machine, the cutting accuracy of scoreboard is without very accurate, and board separator structure
Simply, easy to operate, scoreboard beat is short, thus its to compare milling machine production cost low, production efficiency is high.In view of body electronics control
Device cost processed is relatively low, and production line carries out the mode of manual segmentation circuit board using board separator at present.
Common manual scoreboard equipment, is mainly made up of jettron and two blades, and blade is each a piece of up and down, is used for
Scoreboard, upper bottom knife X-direction stagger 0.1mm, when circuit board is pushed into and triggers blade in the edge of a knife and close knife, prevent that now blade touches
Hit.During scoreboard manual with common manual scoreboard equipment, the circuit board both sides of operative employee's hand held tape Pin pins (contact pin), by circuit board
The junction V grooves alignment edge of a knife is manually pushed back into the edge of a knife, and after triggering pneumatic travel switch, the edge of a knife directly cuts off connecting plate muscle, completes scoreboard
Work.Although which compares milling machine relatively low production cost and higher production efficiency, but its defect is also obvious,
The hand of operative employee need to hold circuit board and push it into the edge of a knife during scoreboard, and band Pin pins circuit board is exposed to device external, operating personnel
In scoreboard, circuit board overlong time of the hand contact with Pin pins, hand easily touch Pin pins, bring Pin pins to be touched curved wind by hand
Danger, and so caused product rejection can not be reprocessed, so as to cause higher scrap cost, meanwhile, connecting plate V grooves are aligned
Spend the time longer during the edge of a knife.
