On the basis of test instrument system, increase product jig automatic plug, and control the switching of double-station by control box, comes
It realizes the voltage-withstand test of power supply, has and save manpower, it is high-efficient, while plug number of the product on jig is decreased, it is good
The high feature of rate.
In the present embodiment, further includes degradation before the Hi-pot test step, set using automatic aging equipment
Temperature environment Imitating testing charger performance.Automatic aging equipment is replaced by Stacking Robots manually, certain
Under temperature environment, realizes that automatic loading/unloading carrys out a kind of aging techniques of simulation test properties of product, while saving manpower, promoted
Efficiency, reduces aging energy consumption, monitors aging data automatically, realizes docking for test data and plant data management system.
In the present embodiment, the charger is USB charger, and production technology of the invention is suitable for the life of various chargers
Manufacture is produced, especially USB charger series charger, high degree of automation, production efficiency and processing quality are higher.
It is illustrated in figure 3 a kind of embodiment three of charger automatic production process, production craft step are as follows:
It throws plate → dispensing → plug-in unit → welding → inspection solder joint → repair welding → ICT → functional test → and cuts foot → brush board → survey
Foot height → dress partition → dispensing → scoreboard → dress PCBA → pressure PCBA → capping → GAP inspection → Step inspection → laser carving → outer inspection
→ energization test → aging → Hi-pot test → functional test → total inspection → PE bags → puting and packing of dress.
Wherein dress PCBA includes automatic dress PCBA board and pressure two steps of PCBA, and capping step includes loading onto lid, pressure upper cover
With three steps of ultrasonic bonding.
Replaced manually using automatic upper panel device, the pcb board being stored in turnover box is transmitted on production line one by one, when
After pcb board in turnover box all transmits, empty turnover box is downloaded automatically, and instead next fully loaded turnover box.
In dispensing step, replace manual operation using automatic dispensing machine, speed is fast, and high-efficient, precision is high.And manual dispensing
With complicated for operation, speed is slow, accuracy is low, is easy error, and the operation of complex figure can not be carried out, it is even more impossible to realize life
The disadvantages of producing automation.When product process of passing through tunnel furnace, the glue put on pcb board is solidified by temperature control system, thus
Shorten aerial curing time, improving production efficiency.
In plug-in unit step, in plug-in unit step, deformed insertion machine is suitable for various temperature electronic component plug-in units, solves existing
The plug-in unit problem for the component for having plug-in machine that cannot insert, it is alternative artificial, save a large amount of labours, realize automatic production line and from
A kind of robot of dynamic factory operations.
In welding step, wave-soldering is to allow the welding surface of card directly to contact with high-temperature liquid state tin to reach welding purpose.
Foot equipment is cut using manual or automaticization to cut the pin more than height.
In solder joint inspection step, online AOI is with special-purpose multifunctional detection algorithm abundant and binary or grey level
Optical imagery processing technique carry out detection wave soldering quality, can improving production efficiency, save production manpower, find earlier
Welding defect, and reliability is relatively artificial good.
Online AOI is with special-purpose multifunctional detection algorithm abundant and binary or grey level's optical imagery processing technique
Carry out the quality of detection wave soldering, can improving production efficiency, save production manpower, find welding defect earlier, and is reliable
Property it is relatively artificial good.
Solid-state solder stick is heated by the soldering iron heated automatically and is melted, while by means of the effect of scaling powder, making its stream
Enter by between weldering metal, forms solid and reliable pad after cooling.The process all leans on machine itself to complete, and completes
Instead of artificial, and quality is got well than manually, and efficiency also improves.
It in brush board step, is combined, is realized automatic to tin sweat(ing)/rosin/dust is remained on pcb board with hairbrush by manipulator
Cleaning, to replace artificial, promotion operating efficiency.
Cut step it is rapid in, by laser sensor, optical fiber can CCD detection system, and combine manipulator, realize to pcb board
The detection of upper plug-in unit part pin superelevation, measurement accuracy is high, and efficiency is fast, good reliability.
In ICT test and functional test step, replace it is artificial, by the electrical property to online component and be electrically connected into
Row test manufactures defect and a kind of undesirable standard testing means of component to check.It mainly checks online single member
The opening of device and each circuit network, short-circuit conditions, have the characteristics that it is easy to operate, quick rapidly, fault location it is accurate.
In functional test step, on the basis of original manual test jig and test instrument system, increase product jig
Automatic plug, and the switching of double-station is controlled by controlling box, the test of Lai Shixian power supply function has and saves manpower, effect
Rate is high, the high feature of yield.
In scoreboard step, link the plate of multi-disc after scolding tin, route can be injured often or roll over electronic component by manually fractureing
Disconnected, automatic board separator is divided with walking blade and advancing, and can thoroughly reduce stress, prevents solder joint cracking and part breaking, improves production
Efficiency and quality.
By the positioning mechanism of manipulator and dress PCBA, Mechanism Combination is inserted, PCBA is manually packed into shell automatically by substitution,
Improve production efficiency and quality.
It is combined by manipulator with the positioning mechanism of fixture, lifting body, control pressurer system, replaces and manually automatically will
PCBA is compressed, it is ensured that PCBA is packed into place.
By manipulator with load onto the positioning mechanism of lid, fetching device combines, and combine upper cover feeding system, replace people
