Specific implementation process is as follows: in use, the multicell by welding encapsulation is placed in feed hopper 22, stepper motor
Drive haul wheel 19 rotate, in the process the pin of the diode in feed hopper 22 fall into one by one successively with 22 face of feed hopper two
In gap between a haul tooth 17, since the wheel face front and rear sides of haul wheel 19 has haul tooth 17, so that diode is being transported
The state that the pin at both ends is clamped by haul tooth 17 is in material wheel 19, haul tooth 17 drives two poles in 19 rotation process of haul wheel
The pin of pipe then drives diode to move along the wheel face of haul wheel 19, and baffle prevents diode and its pin from haul wheel 19
On fall off.Diode follows haul tooth 17 to connect when being moved to the right-hand end of haul wheel 19 with the conducting probe 26 stretched out on baffle
Touching, two pins of diode are contacted with two conducting probes 26 simultaneously from the two sides of haul wheel 19 respectively, are issued from power supply 4
Electric current enters diode by conducting probe 26.If diode is intact and conducting direction is consistent with current direction, power supply
4, the circuit conducting that conducting probe 26, diode, discharge cylinder 2, electromagnet 24 are formed, the energization of electromagnet 24 generate magnetic field and will arrange
The repulsion of magnet 23 on flitch 5 is pushed open so that discharge gate is opened, while discharge cylinder 2 drives discharge bar mobile to discharge gate, row
Scraping wings 3 on material bar releases the pin of diode between haul tooth 17, so that diode falls in biography from discharge gate discharge
It send on band 6.
Another situation, from power supply 4 issue electric current by conducting probe 26 enter diode after, if diode damage or
It extremely puts mistake and causes conducting direction and current direction on the contrary, then power supply 4, conducting probe 26, diode, discharge cylinder 2, electricity
The circuit that magnet 24 is formed cannot be connected, and electromagnet 24, is failure to actuate at the equal no power of discharge cylinder 2, then after stepper motor interval
When rotating again, the continuation of haul wheel 19 is moved down with the diode, and the subsequent diode being moved at discharge gate repeats
The above process.
When not following haul wheel 19 to continuously move to from drain spout from the diode that discharge gate is discharged, pusher cylinder 9 is synchronous
Movement pushes charging ram to support plate, drives strut, mandril 7 to act in the process, mandril 7 pushes 14 grams of push rod by wedge surface 15
It takes the effect of pressure spring 16 to move down, the scraping wings 3 of 14 bottom end of push rod pushes the pin for the diode being located above drain spout, by two
Pole pipe is detached from haul wheel 19 and is pressed into guide pipe and reversing piece 10.If being already filled with diode in reversing piece 10 or having diode card
Firmly, then the movement of push rod 14 can the diode in auxiliary pushing reversing piece 10 move down.If in reversing piece 10 diode-less or
Only a small amount of diode when, diode be spontaneously decoupled under the effect of gravity haul wheel 19 and pass through drain spout from guide pipe enter change
To part 10.The end of each pin is rotated each along spiral helicine sliding slot 8 during diode is mobile in reversing piece 10
It moves down, so that diode moves down in reversing piece 10 around the rotating middle part of oneself simultaneously, limits the spiral coil of sliding slot 8
Number, so that diode is just exchanged by the placement position of 8 latter two pin of sliding slot, then diode is from 10 lower end of reversing piece
Guide pipe drops in support plate.
Diode in support plate is under the pushing of the charging ram that pusher cylinder 9 drives and scraping wings 3 thereon to moving to left
Dynamic to enter returning charge part 12, the diode in returning charge part 12 cannot be fallen by the blocking of protrusion 11 and the support of lower section diode,
With the continuous entrance of diode in returning charge part 12, wherein the diode for being located at the top is gradually mobile to return port 13.Returning charge
Diode in part 12 enters between baffle and the wheel face of haul wheel 19 during continuing to move to after reaching return port 13, and two
The pin of pole pipe enters between haul tooth 17, while haul tooth 17 drives diode to continue edge during haul wheel 19 rotates
Haul wheel 19 wheel face it is mobile until again moving at feed hopper 22.The diode again moved at feed hopper 22 is again heavy
Multiple above-mentioned the step of being moved at discharge gate, if the diode does not damage, its conducting direction is and two after split pole commutates
Current direction between a conducting probe 26 is consistent, then may make electromagnet 24 and discharge cylinder 2 act it is discharged.By
The diode of above process discharge is arranged according to unified conducting direction, and diode can be sent into ink print by conveyer belt 6
Dataller's sequence carries out the identification printing of conducting direction, and whole process does not need the polarity of manual operation sorting diode, high-efficient, effect
Fruit is prominent, can effectively improve the production efficiency and quality of diode.
