Description
Technical Field
[0001] The invention relates to the technical field of diode manufacturing, and in particular to a diode electrode lead loading device and a loading method. Background Art
[0002] The plastic-encapsulated coaxial diode is composed of two copper electrode leads and a semiconductor chip connected in series axially, and then the plastic is encapsulated and cured. The plastic-encapsulated coaxial diode has many advantages in terms of simple packaging, low price, small forward voltage drop, high response frequency and fast recovery, etc. It is widely used in electronic product rectifier circuits, high-frequency oscillation circuits, fast recovery circuits and other circuits. The copper electrode lead is a reducer as a whole, including a larger diameter end and a relatively thin rod, and a step surface is formed between the rod and the end. The bulk supply of copper electrode leads is in a disordered and scattered state. In large-scale production, a certain number of copper electrode leads must first be neatly and orderly loaded into the high-purity graphite disk. At present, manually adding copper electrode leads to high-purity graphite disks is not only inefficient, but also easy to stick and contaminate the leads, reduce the characteristics of the chip, and affect the product yield. The patent application of Zhuali with publication number CN103794521A discloses a transition tray filling machine for copper electrode leads of plastic-encapsulated coaxial diodes. The copper electrode leads are lifted to a certain height during the rotation of the drum and then fall onto the coarse sorting plate, sliding down along the slide on the coarse sorting plate; the copper electrode leads sliding out of the coarse sorting plate fall onto the fine sorting plate, and the copper electrode leads in the slide slide down along the slide; the falling copper electrode lead rods touch the upper edge of the front wall of the directional wire collecting bin body, and the copper electrode leads slide along the front wall into the directional wire collecting bin body and are discharged in a direction by the wire outlet pipe; the discharged copper electrode leads are stored in the squares of the transition tray, and under the action of vibration, the copper electrode leads in the squares enter the lead accommodating holes of the lead transition tray below, thereby realizing the directional sorting of the copper electrode leads. Although this technical solution can realize the automated directional sorting of copper electrode leads and the filling of copper electrode lead transition trays, in the actual production process, since there is always a certain proportion of diode leads that cannot correctly enter the diode channels of the coarse sorting plate and the fine sorting plate, it will cause the plastic-encapsulated coaxial diode copper electrode lead transition tray filling machine to jam, requiring frequent shutdowns for maintenance. Sometimes, individual electrode leads may not correctly enter the electrode lead transition tray, affecting the subsequent packaging quality. Summary of the invention

By adjusting the electrode lead sliding direction channel 33, the central axis of the electrode lead 10 is roughly distributed longitudinally.
[0065] Step 3: The coarse sorting plate vibration driving motor 44 vibrates, and the electrode leads 10 enter the coarse sorting plate lower sliding channel 41 of the coarse sorting plate 4, and most of them enter the first gap 51 from the guide shoe 42 and hang on the first gap 51; most of the electrode leads 10 hanging on the first gap 51 enter the second gap 71 directly in front of it through the drop hole 52 and hang on the second gap 71; a small amount of electrode leads 10 not hanging on the first gap 51 enter the horizontal collecting groove 61 and enter the unsorted electrode lead collecting basin 63 through the first connecting channel 62.
[0066] Step 3: The second fine sorting plate vibrates the driving motor 73, and a very small amount of the electrode leads 10 hanging on the second slit 71 are swept by the brush 67 into the third connecting channel 65 closest to them and enter the unsorted electrode lead collection basin 63 through the third connecting channel 65; the electrode leads 10 hanging on the second slit 71 fall from the front end to the third slit 81 of the third fine sorting plate 8 and hang on the third slit 81. When the third slit 81 is full of electrode leads 10, the electrode leads 10 hanging on the second slit 71 fall from the front end to the gap between the rear side surface of the second longitudinal column 82 and the front side surface of the first longitudinal column 74 directly behind it and enter the unsorted electrode lead collection basin 63 through the second connecting channel 64.
[0067] Step 4: The electrode lead 10 at the front end of the third slit 81 enters the combing groove 93 of the comb bar 91, and the comb bar 91 moves back and forth laterally. The comb bar 91 sends the electrode lead 10 in the combing groove 93 into the conduit 95 at the bottom of the vertical groove 94 of the third fine sorting plate 8 and resets it. The longitudinal movement device of the transition plate drives the transition plate 92 to move longitudinally; the electrode lead 10 falls from the conduit into a row of wire storage holes 96 of the transition plate 92, thereby realizing the loading of the electrode lead.
