Abstract

PURPOSE:To automate setting and to improve productivity by providing a leaf spring which performs continuously pressing motion from advancing motion and a comb tooth-shaped setting fitting having plural sheets of guide shapes and pressing a lead wire. CONSTITUTION:A leaf spring 12 advances upon advancing of a mounting plate 7 for the leaf spring and the slope of a bracket 14 lowers a cam follower 15 at the bottom end of a rod 9 when the spring moves horizontally in certain section. The spring 12 presses consequently an electronic part 16 while advancing. A boss 17 fixed to a block 6 contacts with a block 18 and presses a link 19 in this stage. The tensile force of a spring 20 acts on the block 18 and therefore a block 22 operates around a center pin 21 and rotates a setting fitting 23 at the top end. The lead wire of the part 16 is set to the central part of the electronic part 16 by the above-mentioned method. Automation is thus made possible and production efficiency is improved.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a lead having two parallel lead wires used when performing processing operations such as welding and processing electronic components such as crystal oscillators. This invention relates to a line correction device.

(Composition of conventional example and its problems) Conventionally, lead wire correction has been carried out by a worker manually redirecting the lead wire with his or her fingertips when manually setting a workpiece such as an electronic part on a welding electrode or mold. Correct the gap or
Alternatively, lead deflection was detected by a touch sensor or the like, the machine was stopped, and after the machine stopped, an operator corrected the lead deflection, resulting in a low machine operating rate and an obstacle to automation.

(Objective of the Invention) The present invention eliminates the above-mentioned conventional drawbacks, and is intended to prevent damage to electronic components and other workpieces caused by welding pressure electrodes or press molds, etc. In order to prevent damage to piezo electrodes and press molds, the purpose is to correct bends in lead wires as a pre-process of welding or press working, and to improve production efficiency.

(Structure of the Invention) The present invention provides an apparatus for correcting bends in lead wires of electronic components, etc., which is composed of two parts, a cap and a base, and has two parallel lead wires attached to the base part. The holding method involves pressing down the base of the electronic component using a continuously operating leaf spring, and then using a plurality of V-shaped pieces or a comb-shaped piece having a corresponding guide shape. The correction fitting is configured to correct the alignment direction of the lead wires in a direction intersecting the two parallel lead wires. The straightened lead wire is straightened within the range of the lead wire relief hole provided in the welding pressurizing electrode or the press mold on the pressurizing side, and the lead wire can be welded or press processed without deforming or damaging the lead wire. becomes possible.

(Explanation of Examples) Next, the present invention will be explained in detail.

FIG. 1 shows an exploded perspective view of an electronic component to be corrected used in the present invention, in which 1 is a base, 2 is a cap, and 3 is a lead wire.

FIG. 2 shows a cross-sectional view of the electronic component shown in FIG. 1, in which one with bent leads is set on the fixed electrode 4 for welding.

FIG. 3 shows a front view of an embodiment showing the structure of the lead wire straightening device of the present invention, FIG. is the third
A plan sectional view of the lead wire correction fitting part in the figure is shown.

In FIG. 3, when the air cylinder 5 fixed to the bracket 24 moves forward, the block 6 fixed to the rod of the air cylinder 5 moves forward, and the leaf spring mounting plate 7 moves forward due to the restoring force of the spring 8. The leaf spring mounting plate 7 is fixed to a rod 9, and the rod 9 is floated by a spring 11 with a slide block 10 as a guide.

When the leaf spring mounting plate 7 moves forward, the slide block 10 also moves forward along the rod 13, and the leaf spring 12 fixed to the leaf spring mounting plate 7 moves forward.

When the leaf spring 12 moves forward horizontally in the section consisting of the rod 1
3, the cam follower 15 attached to the end of the rod 9 engages with the inclined part of the bracket 14, and the plate spring mounting plate 7 moves downward while moving forward. The plate spring 12 presses down the electronic component 16.

At this time, the boss 17 fixed to the block 6 hits the block 18 and pushes the link 19. A tension force is applied to the block 18 by a spring 20. When the link 19 moves forward, the block 22 operates using the center pin 21 as a fulcrum, and the claw-shaped correction fitting 23 fixed to the block 22 rotates using the center pin 21 as a fulcrum, pinching the lead wire of the electronic component 16. In this way, approach the center and correct the lead wire to the center. In addition, the fifth
19', 22' and 23' shown in the figure are symmetrical parts facing the link 19, block 22 and correction fitting 23, respectively. The bracket 24 and the bracket 14 are fixed to a base 25, and the base 25 is fixed to a main body or the like (not shown).

(Effects of the Invention) As explained above, according to the lead wire straightening device of the present invention, damage to welding electrodes, press molds, etc. and damage to workpieces such as electronic components can be prevented, and this device can be incorporated into a welding machine, etc. This has the advantage of promoting automation and improving production efficiency.
