Transverse plastic-sealed diode lead wire straightening machine

Abstract

The invention relates to a plastic-sealed diode lead wire straightening machine, in particular to a transverse plastic-sealed diode lead wire straightening machine which comprises a feeding device, a lead wire straightening device and an automatic control system. An upper depended wheel and a straightening roller in the lead wire straightening device are arranged on a concentric shaft and are integrally fixed on a small wallboard; a lower depended wheel and a supporting roller are arranged on a concentric shaft and are integrally fixed on a large wallboard; a driving shaft, a braking shaft, the supporting roller and a tensioning wheel are connected by a feeding belt; the upper depended wheel and the lower depended wheel cling to each other; the gap between the straightening roller and the feeding belt form a strengthening channel; the straightening roller and the feeding belt do relative differential movement; and the feeding device comprises a vibrating choosing bin and a vibrating feed table. The transverse plastic-sealed diode lead wire straightening machine straighten diodes by utilizing a simulated manual transverse straightening method, has the advantages of high qualified product rate, high production efficiency, strong processing adaptability, high intelligence degree, low maintenance cost, and the like, and is convenient in operation.

Description

technical field [0001] The patent of the present invention relates to a straightening machine for lead-out wires of plastic-encapsulated diodes, in particular to a straightening machine for lead-out wires of transverse plastic-encapsulated diodes. Background technique [0002] Plastic-encapsulated diodes are widely used electronic components in the electronics industry. Due to the limitation of the process in the process of tinning the lead-out wires of plastic-encapsulated diodes, the lead-out wires of the diodes will often bend, which prevents the diodes from entering the next processing procedure.

Problems solved by technology

[0002] Plastic-encapsulated diodes are widely used electronic components in the electronics industry. Due to the limitation of the process in the process of tinning the lead-out wires of plastic-encapsulated diodes, the lead-out wires of the diodes will often bend, which prevents the diodes from entering the next processing procedure. As a plastic-encapsulated diode in my country The main production countries, due to the limitation of the straightening process of the diode lead wires, have seriously affected the production efficiency and economic benefits of the factory

[0003] The traditional lead wires of plastic-encapsulated diodes are mainly manually straightened by hand rubbing, which is inefficient and unable to meet the needs of large-scale industrial production; at the same time, because diodes are low-value-added products, the price is relatively low. With the increase of labor costs, Factories and enterprises can no longer rely on manual methods for manual alignment

In this case, there is an urgent need for mechanical straightening machines to replace the mechanized operations of manual straightening. In order to solve this problem, various straightening machines have been invented, but similar straightening machines have the following disadvantages: (1) The first part is directly applied to the lead-out wire of the diode. Since there is a tin-plated layer on the surface of the lead-out wire, it will have a greater adverse effect on the electroplating layer after processing; (2) the vertical processing method is used to straighten the lead-out wire of the diode, and the general part is If a channel is used for continuous operation, if a certain output is obtained, the running speed of the machine can only be increased, which will cause great damage to the machine. If the machine fails, the operation can only be stopped, and the production efficiency is low; (3) the existing general use of belts to The lead-out line is straightened by pressing the straightening method, which will cause a large loss to the belt and increase the operating cost of the enterprise; (4) the existing straightening machines are generally only a single mechanical design, which is not suitable for various conditions in the diode transmission process. Does not have automatic adjustment, fault removal, and alarm functions, and has a low degree of intelligence
