Description

AUTOMATIC APARATUS MANUFACTORING FOR BACK LIGHT MARK FOR CELLULAR PHONE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic assembly of electronic components, and in detail, to an apparatus for automatically assembling a backlight used for a portable telephone sign.

Conventionally, a backlight used for a sign of a portable telephone is a light guide plate composed of light emitting diodes.

Korean Laid-Open Patent Publication No. 98-23438 describes a light emitting diode for an LCD backlight and a keypad, which operates only under a certain brightness and adjusts an operating time of the light emitting diode according to the actual use time of the portable telephone. It relates to the operation structure of the light emitting diode for LCD backlight and keypad,

As a liquid crystal display device using a backlight having an LED as a light input means in Korea Registration Utility Model Publication No. 130515, in order to prevent adverse effects on the image quality of the liquid crystal display device due to the hot spot phenomenon of the LED, In the liquid crystal display which not only uses a backlight including an LED as a feeding means, but also attaches a plurality of short portions of a conductive member between the upper and lower substrates of the liquid crystal display device to conduct the upper and lower substrates. An auxiliary sealant having a predetermined length between the upper and lower plates into the seal line of the sealant to which the plate is attached has its center line according to the arrangement state of the LED and its center line according to the arrangement state of the LED. It can be seen that the present invention relates to a liquid crystal display device which is applied while being matched.

Conventional techniques have been economical problems such as the backlight assembly of the mobile phone signs are manual or semi-automatic, requiring a large number of people in mass production.

The present invention is to solve the problems described above, by mounting a light guide plate containing a light guide plate in the rod at the same time operating the process of element insertion, lead cut, forming, measuring, marking at five places, as well as continuous supply and continuous discharge It is an object of the present invention to provide a device for automatically assembling a backlight used in a portable telephone sign that is designed to be possible.

In order to achieve the above object, the present invention is designed to automatically move the finished product discharged from the transfer unit designed to automatically move the light guide plate automatically supplied from the rod to the transfer unit (unit to assemble parts) to the unloading unit. ('B' part) relates to the automatic backlight backlight unit

Partpartida lift unit of the present invention is installed on the upper portion of the transfer part, it is designed to be inserted into the light guide plate by the single axis robot by the sub-motor control,

The conveying unit is a device for assembling individual parts and designed to insert, lead cut, form, measure and mark the elements at one point.

The parts assembled in the conveying part are the automatic backlight unit of the cell phone sign that is packed in the packing material of the unloading part.

All of the above processes were installed to be controlled automatically in the control box.

When described in detail with reference to the drawings as follows.

1 is a work flow diagram of the transfer unit of the automatic cell phone sign backlight assembly of the present invention,

2 is a plan view of the backlight automatic assembly device of the mobile phone sign of the present invention, Figure 3 is a backlight automatic assembly device of the mobile phone sign of the present invention, A: front view, B: side view, Figure 4 is a load / unload lift assembly of the present invention Fig. C is a plan view, D is a front view, E is a side view, and Fig. 5 is a parts lifter of the present invention, F is a plan view, G is a front view, H is a side view, and Fig. 6 is a forming part of the present invention. Front view, J: side view, and FIG. 7 are measuring sections K: front view, L: side view, and FIG. 8 of the present invention, M: front view, N: side view, and FIG. As one,

The work order is to transport the light guide plate to the vacuum pad by the single axis robot in the load unit of the backlight automatic assembly device of the mobile phone sign of the present invention shown in Figures 2 and 3,

In the first to third steps, the light guide plate is positioned.

The third transfer is performed to the insertion part of the fourth step, the elements in which the light emitting diode chip is embedded are aligned in the parts pda, and the aligned elements are inserted into the light guide plate by the single axis robot.

After cutting the lead by the fourth transfer to the fifth step lead cut section,

Step 6 The fifth feed is performed to the forming part of FIG. 6, and the lead is bent at 90 ° by the air cylinder and the rotary roller on the LM guide.

Step 7 Measures by making a sixth transfer to the measuring unit of FIG. 7 and inspects short, lighting and various other items as an electrical property test.

Eighth step Transfer to the marking part of Fig. 8 by the seventh marking on the bottom of the light guide plate, marking the country of origin and specifications such as the factory name with black ink,

The ninth step is transferred to the unloading unit to align and package the product in the film case.

In these processes, that is, the load and unload portions are conveyed by a single axis robot.

This is a device that automatically assembles the backlight of a mobile phone sign that is completed in several steps.

The process is composed of stages, but at the same time the work in each stage,

It is a device that is automatically transported to the next stage at the same time and all the continuous work is operated by the control box and proceeds automatically.
