JPH07251334A - Positioning mechanism for thin platelike parts - Google Patents

Abstract

PURPOSE:To provide a mechanism, by which thin platelike parts can be reversed and positioned at a very low cost, and the parts can be positioned without reversed when it is not necessary to reverse the parts. CONSTITUTION:With a reversing guide 2 moved on a positioning guide 1 by a reversing guide driving part 3, when a thin plate-like part 4 is separated from an upper chuck part 6 above the positioning guide 1 to freely fall, the thin plate-like part 4 is brought into contact with the tip of the reversing guide 2 to be reversed and falls in the positioning guide 1, so that the thin plate-like part 4 is positioned in its reversed state. While the reversing guide 2 is not moved on the positioning guide 1 by the reversing guide driving part 3, when a thin plate-like part 4 is forced to freely fall, the thin plate-like part 4 falls in the positioning guide 1 without contacting the tip of the reversing guide 2, so that the thin plate-like part 4 is positioned without being reversed.

Description

Detailed Description of the Invention

[0001]

[Industrial application] A thin plate-like part suitable for an assembly / processing machine that needs to handle light and thin flat parts such as plates, and perform inversion / positioning and non-inversion / positioning of the parts. Regarding the positioning mechanism.

[0002]

2. Description of the Related Art Positioning of a component or an assembling / processing machine is very important for assembling or machining a component, and a mechanical chuck is disclosed in Japanese Patent Laid-Open No. 55-48942 as a method for positioning the component. There is a method of fixing the component to the positioning guide using. Further, as a method of positioning the assembling / processing machine, a method of detecting the position of a part by using a camera and positioning the assembling / processing machine in accordance with the part is adopted, as in Japanese Patent Laid-Open No. 55-98842. .
Furthermore, as a method of positioning after reversing the parts,
There is also means such as Japanese Patent Laid-Open No. 4-322916 for performing reversal and positioning using a mechanical rotation mechanism.

[0003]

Since the above-mentioned means is costly, it is expensive when manufacturing an assembling / processing machine. Also, if the parts are extremely thin, positioning becomes difficult. An object of the present invention is to provide a mechanism capable of performing reversal positioning of a thin plate component at an extremely low cost, and performing repositioning without reversing when there is no need for reversing.

[0004]

To achieve the above object, the present invention comprises a positioning guide for positioning a thin plate-shaped component, a reversing guide, and a reversing guide driving section for driving the reversing guide. Is moved to a position above the positioning guide when driven by the reversing guide drive unit, and the thin plate-shaped component that falls freely from above the positioning guide is reversed by the tip of the reversing guide and dropped into the positioning guide. When not driven, the thin plate-shaped component, which is located outside the positioning guide and falls freely from above the positioning guide, is dropped into the positioning guide without being inverted, thereby positioning the thin plate-shaped component.

[0005]

[Function] By moving the reversing guide onto the positioning guide by the reversing guide driving section, the thin plate-shaped component freely falls from above the positioning guide. Then, the thin plate-shaped component is positioned in the inverted state.
Further, by freely dropping the thin plate-shaped component from above the positioning guide without moving the reverse guide on the positioning guide by the reversing guide drive unit, the thin plate-shaped component falls into the positioning guide without hitting the tip of the reversing guide, The thin plate-shaped component is positioned in a state where it is not inverted. As a result, in processing / assembly using a thin plate-shaped component, reversal or non-reversal of the component and subsequent positioning can be realized with a low cost and simple mechanism.

EXAMPLE An example to which the present invention is applied will be described below.
In the embodiment, a pull-out component supply unit which is a part of a cable connector cover automatic assembling apparatus to which the present invention is applied will be described. Before that, an assembled state of the entire connector which is a product will be described with reference to FIG. This connector is for a flat type multi-core cable, and the connector 1 to which the cable 13 is connected
The covers 15 are attached to both sides of the cover 4. Then, a pull-out component 4 (hereinafter, abbreviated as a component) is attached for inserting / removing the connector 14. The receiving side connectors 16 into which the connectors 14 are inserted are vertically arranged in two rows, and there are two types of parts 4 attached to the front side and the back side of the cable 13 in consideration of the ease of pulling out. Further, the component 4 has a nameplate 8 indicating the mounting destination of the connector. Since this nameplate 8 needs to be confirmed from the outside, if the component 4 is attached to the back side of the cable 13, the nameplate 8
It may happen that the part 4 with the
Inversion of the part 4 occurs during the assembly process.

FIG. 1 illustrates a component positioning mechanism and a component transport mechanism according to an embodiment. 1 is a positioning guide, 2 is a reversing guide, 3 is a reversing guide driving unit, 4
Is a part, 5 is a parts / nameplate conveying part, and 6 is a parts chuck part. The operation of these mechanisms will be described in detail in the description of FIG.

Next, the component supply unit to which the present invention is applied and its operation will be described with reference to FIG. The components 4 are fed from the component replenishing unit 9 one by one by a feeding mechanism and moved to the nameplate attaching unit 10. The nameplate 8 attached to the component 4 is printed by the printer 11 and then placed on the nameplate standby unit 12. The printed name plate 8 is chucked by the name plate chuck / sticking unit 7 in the parts / name plate conveying unit 5 and stuck onto the part 4. The sticking position of the nameplate 8 on the part 4 varies depending on which side of the cable the part 4 is attached to. The sticking position is controlled based on the information by the computer controlling the production of the cable. Then, the position of the parts / nameplate conveying unit 5 is controlled, and the components are attached by the nameplate chuck / attaching unit. In this example, the parts / nameplate transfer unit 5 is composed of a ball screw and an air cylinder, and X, Y,
3-axis Z motion is possible. The nameplate chuck / adhering unit 7 is composed of a vacuum suction device.

The component 4 to which the nameplate 8 is attached is chucked by the component chuck unit 6 in the component / nameplate conveying unit 5.
It is carried onto the positioning guide 1 by the nameplate carrying section 5. Whether the parts are reversed or not is instructed by the production control computer,
When there is reversal, the reversal guide drive unit 3 operates and the reversal guide 2 is arranged on the positioning guide 1. If there is no reversal, the reversal guide drive unit 3 does not operate, and the reversal guide 2 is arranged at a position deviated from the positioning guide 1. Here, a vacuum suction device is used for the component chuck portion 6, and an air cylinder is used for the reversal guide drive portion 3.

In the positioning, the component 4 freely falls by releasing the chuck of the component chuck portion 6, and when there is no reversal, as shown in FIG. 2, it falls directly into the positioning guide 1 and is positioned on the positioning surface a. It When there is reversal, as shown in FIG. 3, the component 4 hits the reversal guide 2,
It is rotated and turned over and falls into the positioning guide 1,
It is positioned on the positioning surface a. As shown in FIG. 3, in order to reverse the parts, the position of the tip of the reversing guide 2 is set to be inside the position of the part gravity center G of the part 4. Further, in order to reliably reverse the component 4, the distance A between the reversing guide 2 and the positioning surface a is set to the component 4
It is necessary to take more than half of the component size B of. Since the positioning guide 1 is provided with a taper, some fluctuations of the parts at the time of dropping are absorbed, and reliable positioning can be obtained. In the parts supply section, the nameplate standby section 12 and the nameplate pasting section 1
It goes without saying that there is no problem in any arrangement of the positioning guide 1 as long as it is within the range in which the mechanism of the parts / nameplate conveying unit 5 operates. Also, the component chuck 6
The nameplate chuck and sticking section 7 may be shared as shown in FIG.

In the subsequent steps, the component 4 is assembled to the connector by the robot. In this device, when the component 4 is assembled, a sophisticated mechanism for recognizing and correcting the deviation is added. Therefore, if the component 4 is not positioned in advance, proper assembly cannot be performed and a defective product is manufactured. Therefore, this positioning mechanism is required.

[0012]

According to the present invention, in processing / assembly using a thin plate-shaped component, reversal or non-reversal of the component and subsequent positioning can be realized with a low cost and simple mechanism. Further, it is possible to reduce the size of the processing / assembling device that requires the positioning means.
