First, the tray 200 is supplied to the tray loading unit 300 on the left side, the tray 200 has a structure that can be loaded up to 20 sheets. Of course, the number of stacking may be changed. The tray 200 is lifted toward the pickup unit 1300 by a lifting device 400 for loading, which is configured to feed up and down. The process is shown in detail in FIG. 8 and will be described in more detail below.

First, when several trays 200 on which the device 100 is placed arrive (FIG. 8 ①), the lifting device 400 for loading is operated to raise to a predetermined height (FIG. 8 ②). The height adjustment can be easily made using a sensor or according to a pre-input value.

Next, the step motor 12 (see FIG. 7) provided on the left and bottom adjustment pieces 510 is operated to fit the width and length of the tray 200 (FIG. 8 ③).

Then, the support blade 1350 installed on the adjusting piece 510 is inserted between the trays 200 so that only one sheet is raised to a predetermined height (for example, 20 mm) separately (Fig. 8 ④). To this end, the hydraulic cylinder 512 for horizontal and vertical movement is installed on the support blade 1350, respectively. The support blade 511 is connected to the rail of the buffer unit 1100 and the support blade of the place unit 700, so that the forward movement of the tray 200 can be easily performed.

Next, the lifting device 400 is moved to the standby position (Fig. 8 ⑤).

As such, when the tray 200 is prepared in the device pick-up unit 1300, the head 500 is moved by a driving device that moves in the longitudinal direction (x axis), the width direction (y axis), and the up and down direction (z axis). Eight pickers 540 in pick up the device 100 and transfer it to the processing unit (rom lighter) 600.

The ROM writer 600 downloads a program to the memory device 100. When the downloading is completed, the ROM writer 600 picks up the device 100 of the ROM writer by using the picker 540 of the head 500. Will be transferred to). For this purpose, at the beginning of operation, an empty tray 200 needs to be prepared in the device place unit 700.

On the other hand, the device determined to be defective in the ROM writing process falls into the defective device barrel (350). To this end, air is temporarily discharged from the discharge hole of the picker 540.

This operation is made possible by operating opposite to the operation of the loading section.

Subsequently, the empty tray 200 placed on the tray buffer unit 1100 is transferred to the place unit 700 using the tray transfer cylinder 550 and the head 500 again.

The above operation is continued continuously, and the ROM writing operation for the set of memory devices 100 contained in the tray 200 is completed.

The device place part 700 is capable of changing its width in the longitudinal direction (x-axis direction) and in the width direction (y-axis direction), and drives the stepper motor 12 to widen or narrow the adjusting piece so that the tray 200 can be changed. If the size is changed to the width and width of the box, set the space according to the tray size. This is the same as the device pickup unit 1300.

In addition, the tray buffer unit 1100 is capable of changing the vertical size using the manual handle.

It is preferable to keep the accuracy of the robot axis within 10 micrometers in the X, Y, and Z directions.

Pickers 540 installed in the head 500 is composed of eight, controlled to be operated individually, each must have a vacuum adsorption function, air discharge function. For example, when the device 100 is picked up, a vacuum of 0 to 100 kpa is used, and when the device 100 is placed, the vacuum is cut off and the air for digging is discharged at a pressure of 5 to 7 kpa at 10 to 100 msec. In order to increase the production per hour, it is necessary to increase the number of pickers 540.

According to the present invention having the above-described configuration, since the supply and discharge of the tray on which the memory device is loaded can be automatically and continuously performed, there is an advantage that the productivity can be greatly increased.

In addition, even if the size of the tray is changed, there is an advantage that the size of the pickup, buffer, and place can be easily changed.
