Description

Technical Field

[0001] The utility model relates to the technical field of diodes, in particular to a feeding mechanism for diode production. Background Art

[0002] A diode is an electronic device made of semiconductor materials. A diode has two electrodes, a positive electrode, also called an anode, and a negative electrode, also called a cathode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on, and when a reverse voltage is applied, the diode is turned off.

[0003] During the production process of diodes, it is necessary to weld the two poles of the diode to metal wires. However, in the process of welding the wires of existing diodes, it is necessary to align the two poles of the diode with the metal wires. However, using traditional positioning tools requires that the diode be aligned with the metal wire for welding. Not only is the welding speed slow, but it is also difficult to align the two poles of the diode with the metal wire using a single feed. For this reason, we propose a feeding mechanism for diode production. Utility Model Content

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual Figure 1-4When the utility model is used, the diodes are first stacked on the top of the material box 12. At this time, the output shaft of the limit motor 9 drives the driving gear 10 to rotate, and the driving gear 10 drives the roller 2 to rotate through the driven gear 11. The roller 2 drives the conveyor belt 3 to transport the positioning block 4. The diodes are rolled to the inner wall of the diode positioning groove 5 in sequence through the guide plate 13 provided on the inner wall of the material box 12. The diodes are transported through the conveyor belt 3, and the conveyor belt 3 is transported to one side of the pneumatic reciprocating push rod 14. The push-pull rod 15 is driven by the output shaft of the pneumatic reciprocating push rod 14 to push the push block 16. The diode in the diode positioning groove 5 is pushed into the diode fixing sleeve 18 through the push block 16. The two poles of the diode are leaked at one end of the diode fixing sleeve 18. The two poles of the diode are aligned with the inner wall of the wire limiting groove 20. At this time, it is only necessary to put the metal guide wire into the inner wall of the wire limiting groove 20 to facilitate the alignment of the two poles of the diode with the metal guide wire, which is convenient for welding the diode. Multiple diodes can be pushed into the diode fixing sleeve 18 without single loading, which greatly improves the welding speed of the diode. After the diode is welded, the output shaft of the pneumatic reciprocating push rod 14 continues to drive the push block 16 through the push-pull rod 15 to push out the diode on the inner wall of the diode fixing sleeve 18, and then the output shaft of the pneumatic reciprocating push rod 14 shrinks, and the next batch of diodes are moved to one side of the diode fixing sleeve 18 through the conveyor belt 3, and the diodes are pushed back and forth into the inner wall of the diode fixing sleeve 18 for processing.
