As a result, the two guide rollers 52 rotate by the driving motor 532.

Looking at the operating state of the two guide rollers 52 by the drive motor 532,

The two guide rollers 52 are rotated by the driving means 53 so that each of the pressing protrusions 54 is disposed outward, that is, located at the first inner side and rotated 180 degrees. Up and down movement of the) is made,

When the tray 1 is stopped, the two guide rollers 52 are rotated by the driving means 53 so that the two pressure protrusions 54 located on the stopped tray 1 side of each of the pressure protrusions 54 are formed. Both sides of the tray 1 are fixed by pressure. In other words, the two pressing protrusions 54 are located toward the outside, and the two guide rollers 52 rotate 180 degrees, thereby respectively pressing and fixing both sides of the tray 1.

As a result, each of the pressing protrusions 54 is the two guide rollers 52 so that the tray 1 is arranged at both sides of the tray 1 at its position when the tray 1 stops after a predetermined interval descending or rising by the lifting unit 30. ) Is formed.

Therefore, the pressing protrusions 54 contribute to the tray 1 to be stably fixed by pressing and fixing each of both side portions of the tray 1 stopped after the rising or falling.

In addition, the pressing means (54) and the pressing surface (55, 55 ') may be further provided on the contact surface of the tray (1),

For example, as shown in [a] of FIG. 7, the pressurized means 55 includes a first pad insertion groove 551 formed in the outer wall of each of the pressing protrusions 54 and the first pad insertion groove ( 551 is inserted into and mounted with an adhesive or the like and is made of an elastomeric first pressure pad 552, or

As another example, as shown in [b] of FIG. 7, the pressurized means 55 ′ is provided with a second pad insertion groove formed at a position at which the pressing protrusion 54 is pressed and fixed at the side of the tray 1. 553 and the second pad insertion groove 553 are inserted and mounted by an adhesive or the like, and include a second pressurized pad 554 made of an elastomer.

Therefore, when the pressing protrusion 54 presses the side of the tray 1, the first pressurized pad 552 or the second pressurized pad 554 is stably fixed as the tray 1 is pressed. And slip prevention.

6 and 7, the guide unit 50 is

By further comprising a plurality of support protrusions 56 protruding from the two guide rollers 52 to be spaced apart from each of the pressing protrusions 54,

When the two pressing protrusions 54 pressurize and fix the tray 1, the two supporting protrusions 56 at the lower side of the two pressing protrusions 54 which are press-fixed among the plurality of supporting protrusions 56 are the tray 1. Will support the bottom.

Therefore, the tray 1 is pressed and supported by the two pressing protrusions 54 and the two supporting protrusions 56 when the tray 1 is stopped after the rising or falling.

The storage unit 60

As shown in Figure 1,

It is arranged in an upper portion of the base 10 in the form of a cabinet having a plurality of front open storage spaces 61.

Each of the accommodating spaces 61 stores materials for manufacturing a multilayer printed circuit board separately.

Although the storage unit 60 is arranged above the base 10, the storage unit 60 may be further provided separately on one side or the other side or both sides of the base 10.

On the other hand, in the up-down device according to the present invention

As shown in Figure 4, the base 10 or the guide unit 50 further includes a sensor unit 70 for transmitting a detection signal for the entry and exit operation of the carrier 2 to the control unit 40,

The sensor unit 70 is preferably a limit switch for generating a detection signal by contact when entering the carrier (2).

1 and 2, the two horizontal support 20 is provided with a slip preventing member 21 for the tray (1) on its upper surface,

In addition, as shown in Figure 1 and 2, the front of the base (10) is provided with a shock absorbing member 13 for the carrier (2) to enter,

The shock absorbing member 13 may be formed on the front of the base 10 spaced apart from the left and right, and made of a square pad made of an elastomer material which has a vertical length and is fastened through a bolt or the like.

In addition, as shown in FIGS. 1 and 4, the carrier 2 entering between the two panels 51 passes through the two horizontal supports 20 which descend, and is supported by the two horizontal supports 20. The tray 1 has a structure seated on the carrier 2,

More specifically

A lower frame 2a having casters 2a-1, which are wheels for movement, respectively, at the bottom edges;

Two vertical frames (2b), each standing on both sides of the lower frame (2a),

Two horizontal frames 2c respectively installed on the two vertical frames 2b, and

A handle 2d interconnecting the rear ends of the two horizontal frames 2c and having a grip portion 2d-1.

.

At this time, the two horizontal support 20 is raised or lowered between the two vertical frame (2b) and the two horizontal frame (2c), it is to move the tray 1, the material stacking is completed to the hot press process side When the empty tray 1 is to be loaded and moved between the two panels 51, the tray 1 is placed on the two horizontal frames 2c.

Looking at the operating state of the up-down device for the material seating tray for manufacturing a multilayer printed circuit board according to the present invention having the above configuration,

Load the empty tray (1) on the carrier (2) and enter between the two panels 51 of the guide unit 50,

The two horizontal supports 20 are located in the lower side of the empty tray 1 seated on the carrier 2 in advance, and then the carrier 2 enters.

After the entry is completed, the sensor unit 70 transmits a detection signal to the control unit 40 to cause the control unit 40 to operate the lifting motor 32,

Alternatively, the elevating motor 32 is operated by a button operation provided in the control unit 40 manually.

As the two horizontal supports 20 are lifted by the lifting motor 32, the two horizontal supports 20 are raised while supporting the empty tray 1 seated on the carrier 2.

The worker takes out the materials stored in each storage space 61 of the storage unit 50 and stacks them on the empty tray 1.

When the operator determines that the sheet is stacked up to a predetermined height, the lifting motor 32 is operated by the button manipulation of the control unit 40 to lower the two horizontal supports 20 and the tray 1 seated thereon.

In this case, the distance that is lowered when the button is operated once is lowered by a value preset in the control unit 40.

For example, the control unit 40 may be implemented to control the lifting motor 32 to be operated by a predetermined time using a timer or the like.

When the seating of the material on the tray 1 is completed, the tray 1 is placed on the upper side of the horizontal frame 2c when the position of the tray 1 is located on the lower side of the carrier frame 2c. Raise the two horizontal support 20 through the lifting motor 32 to position and then push the carrier 2 to enter between the two panels 51,

The two horizontal supports 20 are lowered through the lifting motor 32 to seat the tray 1 on the two horizontal frames 2c of the carrier 2, and then the carrier 2 is disposed between the two panels 51. To be removed and moved to the hot press process side.

In the above description of the present invention with reference to the accompanying drawings, a specific shape and structure with a "up down device for a material seating tray for manufacturing multi-layer printed circuit board" was mainly described, but the present invention can be variously modified and changed by those skilled in the art And, such variations and modifications should be construed as falling within the protection scope of the present invention.
