In 77, in the angularity for needing to detect printed circuit board, air bag 69 is filled with enough gas first, then turns adjusting screw rod
612, so that the intermediate position of air bag 69 is reached the maximum value that printed circuit board can tilt to the distance of 3 upper surface of conveyor-belt apparatus,
Due to the compressible property of air bag 69, it can guarantee that circuit board under test can normally be compressed when the angularity of circuit board under test is bad
Air bag 69, rather than it is bad when passing through sense channel in the angularity of circuit board under test, it is logical by detecting due to can not be successfully
Road makes bad printed circuit gradually arch upward, and ultimately causes circuit board and breaks, and after the completion, starts the transmission device of printed circuit board,
Infrared receiving device 74 constantly receives the infrared ray of the transmitting of infrared launcher 75, when the front end of circuit board under test connects by infrared
By device 74 position when, infrared receiving device 74 can not receive infrared signal, and hot outer receiving device 74 receives red again
When external signal, the rear end of surface circuit board under test has already passed through the position of infrared receiving device 74, at this point, using it is certain when
Between after, circuit board will by stop board slot 77, at this moment, 712 energizing magnetic of the first electromagnet, to side plate 79 generate suction
Power, the elastic force for making side plate 79 overcome the first spring 711 drive barrier plate 78 to move upwards, and the part of side plate 79 is made to stretch out barrier plate
Slot 77, when the suction equalization of the pulling force of the first spring 711 and the first electromagnet 712,78 stop motion of barrier plate is to be measured at this time
Circuit board is located at the surface of conveyor-belt apparatus 3, starts motor 61, and motor 61 drives screw rod 62 to rotate, and then drives the first sliding block
65 and second sliding block 610 in rectangular cavity 8 to there is sliding, when by circuit board under test, if when circuit board angularity qualification,
Will not compressing gasbag 69, at this moment when the first sliding block 65 touches the first limit switch 63, the first warning light 4 is bright, prompt should
Circuit board is qualified, if circuit board angularity is unqualified, circuit board will compress 69, and at this moment baroceptor 67 will be experienced
Air pressure change in air bag 69, the second 5 lamps of prompt are bright, prompt the circuit board unqualified, when the first sliding block 65 touches the second limit
When bit switch 64, the stopping of motor 61 waits detection next time, in addition, conveyor-belt apparatus 3 starts qualification in circuit board qualification
Circuit board is transmitted to subsequent processing, and when circuit board is unqualified, the second warning light 5 is bright, waits staff that will not conform to panel and takes
It walks, after the completion, the power-off of the first electromagnet 712 loses magnetism, and under the pulling force effect of the first spring 711, makes barrier plate 78 again
Completely into blocking board slot 77, next printed circuit board is waited to pass through, the first sliding block 65 and the second sliding block 610 are to pass through
Connection component 9 is interconnected, and this set can be selected to avoid when testing agency 6 breaks down due to that can not dismantle
Whole device is replaced, when testing agency 6 breaks down, the fixing bolt on circular trough 616 is unclamped first, removes baffle
68 and fixed plate 611, then start the second electromagnet 917, attracts locking bar 916 to overcome the 4th spring 915 to generate magnetic force
The direction of thrust to close second electromagnet 917 is mobile, when locking bar 916 is detached from locking slot 96, in the thrust of second spring 94
Under, linkage board 93 will will push connecting rod 93 and the first sliding block 65 and the second sliding block 610 is driven to be separated from each other, and during the separation process the
Two electromagnet, 617 power loss, this hour locking lever 916 under the thrust of the 4th spring 912 will with the intimate surface contact of connecting rod 91,
Meanwhile the lower end of straight-bar 911 is slided under the pulling force of third spring 912 on the surface of boss 98, when sliding into rectangular shaft 97
When surface, the upper end of locking bar 916 is located inside fixed block 99, at this moment can remove testing agency 6, can change new inspection at this time
Geodesic structure 6 does not have faulty component that can reuse for some in old testing agency 6, saves cost, when installation, when
When connecting rod 91 is inserted into link slot 92 and compresses second spring 94 by linkage board 93, rectangular shaft 97 is transported with linkage board 93
It moves and moves, the lower end of straight-bar 911 will move to the most significant end of boss 98 again, move in the lower end of straight-bar 911 convex
During 98 most significant end of platform, since straight-bar 911 moves and the top of locking bar 916 and connecting rod to the upper side wall of inner cavity 910
91 surface contact causes the 4th constantly compression of spring 915, when check lock lever 916 is overlapped with locking slot 96, in the 4th spring
Under 915 thrust, it will move to check lock lever 916 in locking slot 96, to keep left-hand thread hole 613 and right-hand thread hole 614 steady
At this moment baffle 68 and fixed plate 611 are being installed on strut 66 and are being fixed by fixed one complete threaded hole of composition.Stopping
Dust in production timely can be blown out placing groove 72 by the hair dryer 76 in mechanism 7, can guarantee infrared receiving dress in this way
The induction part cleaning for setting 74, prevents the induction part of infrared receiving device 74 from polluting and causing maloperation.
Based on above-mentioned, using a kind of printed circuit board (PCB) detecting transmission device of the invention, branch is transmitted in printed circuit board
When supportting the conveyor-belt apparatus on platform, the barrier plate in blocking mechanism moves to the following table face contact with fixed frame, on the one hand prevents
When detecting, printed circuit board is retreated since angularity is bad in testing agency's detection process, on the other hand prevents from examining
When survey, subsequent printed circuit board to be detected is moved in detection zone, and when detection, testing agency in supporting table by moving
The angularity of automatic detection printed circuit board, after the completion, if angularity is qualified, the first warning light is bright, if angularity does not conform to
Lattice, the second warning light is bright, and in addition testing agency situation occurs and needs replacing, the completion replacement behaviour that can be convenient by connection component
Make, which is filled by addition in the transmission device of traditional printed circuit board by the detection and transmission of angularity
Combination is set, detection efficiency and speed are greatly improved, it, can be obvious especially when for absolutely detection angularity requires
Reduce testing time and test human input.
