ICT, i.e. automatic on-line tester are PCBA (the Printed- Circuit Board of hyundai electronics enterprise indispensability
Assembly, printed circuit-board assembly) production test equipment, ICT use scope is wide, and measurement accuracy is high, to what is detected
Problem instruction is clear, is very easy to the general worker of electronic technology level handles problematic PCBA.In—
Circuit-Tester, that is, automatic on-line tester is PCBA (the Printed- Circuit of hyundai electronics enterprise indispensability
Board Assembly, printed circuit-board assembly) production test equipment, ICT use scope is wide, and measurement accuracy is high, to inspection
The problem of measuring instruction is clear, is very easy to the general worker of electronic technology level handles problematic PCBA.It uses
ICT can greatly improve production efficiency, reduce production cost.ICT Test mainly tests probe contact PCB layout and goes out
The test point come detects the welding situation of the open lines of PCBA, short circuit, all parts, can be divided into open test, short circuit is surveyed
Examination, resistance test, capacity measurement, Test Diode, triode test, field-effect tube test, IC pin test (testjet`
Connect check) etc. the neglected loadings of other general and specific components, misloading, parameter value deviation, solder joint even open by weldering, wiring board
The failures such as short circuit, and be which component by failure or open that short circuit is located at which point accurately tells user.
Functional test after the assembling of PCBA circuit board is FCT (Function Test, functional test), its purpose is to
The plank for catching assembly failure, when through analog circuit board actual load at complete machine global function test, to catch be assembled into it is whole
Before machine institute may a Circuit assembly plate defective caught, just find bad so as not to being assembled into after complete machine, also all to tear open
Fall recombination and causes working hour waste and the loss of material.Circuit board can be all used in usual LED display, inserts it in fact in circuit board
Before, to test the function of circuit board, it is therefore desirable to which FCT test utilizes the test point for staying (layout) on circuit board in advance
(Test Point) then draws signal with probe (needle) and picks out to do complete functional test.As long as when test
Plank is put into tester table, then probe is ejected the measuring point for touching plank to be measured by mechanical action, thus may be used
Board under test is modeled to the appearance of connection complete machine, finally all functions of operation test can on board.If whole
Machine is the product for having screen and key, the signal of these spare parts will be all extracted, give an order and look into plank to facilitate
See result；As fruit product does not have screen and key and be connected to computer it is necessary to additionally penetrating transmission interface to operate and check test
Result.
The present invention is divided into upper plate step, transfers step, ICT detecting step, relaying step, FCT detecting step, produces step
Suddenly, lower plate step；At the beginning of test, staff first according to the size of PCBA board to be checked, adjust each component conveying width, under
The position of compression leg, optoelectronic switch position, guarantee that the equipment adapts to PCBA board to be checked.In upper plate step, staff will be to be checked
PCBA board is put into blowing pallet, and helical screw elevator, which rises to blowing pallet, send the conveyer belt of board member concordant, conveyer belt
It is mobile to charging conveyance component with PCBA board to be checked；In transferring step, the position of the pre-adjusted forward and backward guide rail of conveying
It sets, charging conveyance component drives PCBA board to be checked to move to ICT sensing chamber；In ICT detecting step, optoelectronic switch assembly sense
PCBA board in-position to be checked should be arrived, signal is transmitted to electric-control system, ICT conveying assembly stops conveying, and wide bottom seat is adjusted in left and right
The guide rod cylinder of downside declines, and PCBA board to be checked drops down onto the testboard of ICT test suite, and the telescopic cylinder that ICT pushes component returns
Contracting drives lower platen to push, and four lower compression legs on lower platen push down the quadrangle of PCBA board to be checked, and PCBA board is pressed in ICT and is surveyed
On the testboard for trying component, test probe contacts the test point of PCBA board to be checked to detect the open lines of PCBA, short circuit, own
The welding situation of part, if detection is qualified, the left and right jacking cylinder that ICT pushes component is gone up, and is driven ICT to push component and is resetted,
Left and right adjusts the guide rod cylinder of width Its lower side to go up, and ICT conveying assembly is driven to reset, and ICT conveying assembly drives initial survey qualification
PCBA board shifts to the position for transferring driving member；It is alert simultaneously if detecting unqualified, the sound of buzzer sending " drop-drop-drop "
Show the bright orange lamp flashing of lamp, when operator opens ICT clamshell doors, ICT pushes component and resets, and operator takes rejected product away,
ICT conveying assembly resets, and buzzer stops the sound, and warning lamp customization flashes, after operator closes ICT clamshell doors, warning lamp
Restore green light, ICT test member carries out next layer of detection；In relaying step, the position of the pre-adjusted forward and backward guide rail of switching
It sets, transfers driving member and the PCBA board of initial survey qualification is driven to move to FCT sensing chamber；In FCT detecting step, optoelectronic switch assembly
Signal is transmitted to electric-control system by the PCBA board in-position for sensing initial survey qualification, and FCT conveying assembly stops conveying, and left and right is adjusted
The guide rod cylinder of wide Its lower side declines, and initial survey qualification PCBA board drops down onto the testboard of FCT test suite, and FCT pushes component
Telescopic cylinder retraction, drives lower platen to push, and four lower compression legs on lower platen push down the quadrangle of PCBA board, and PCBA board is pressed in
On the testboard of FCT test suite, the test point of the test probe contact PCBA board in the needle plate box of FCT test suite will
PCBA board is modeled to connection complete machine, and test is operated on touching display screen, if detection is qualified, FCT pushes the left and right jacking of component
Cylinder gos up, and drives FCT to push component and resets, and left and right adjusts the guide rod cylinder of wide Its lower side to go up, and drives FCT conveying assembly multiple
Position, the qualified PCBA board of FCT conveying assembly drive shift to the position of discharging conveyance component；If detecting unqualified, buzzer
The sound of " drop drop-drop drop " is issued, while the bright orange lamp length of warning lamp is bright, when operator opens FCT clamshell doors, FCT pushing group
Part resets, and operator takes rejected product away, and FCT conveying assembly resets, and buzzer stops the sound, warning lamp customization flashing, behaviour
After making personnel's closing FCT clamshell doors, warning lamp restores green light, and FCT test member carries out next layer of detection；In producing step,
The pre-adjusted position for producing forward and backward guide rail, discharging conveyance component drive qualified PCBA board to move to automatic board descending machine
Structure；In lower plate step, blowing pallet is concordant with the conveyer belt of board member is sent, defeated when qualified PCBA board enters conveyer belt
It send with driving qualified PCBA board to move into blowing pallet, after blowing pallet piles PCBA board, helical screw elevator falls, stream
Production line out is taken away convenient for staff.The configuration of the present invention is simple, it is easy to use, realize it is full-automatic, can continuous work, section
Less manpower meets production and needs to improve production efficiency, has good market application value.
