Description

Box type tray for PCB for printed circuit board product

The present invention relates to a jig for mounting a PCB (Printed Circuit Board) product, and more particularly, to a PCB product for fixing a PCB product when loading and transporting a PCB product to prevent a defect occurring during handling such as a scruch, The present invention relates to a box type tray.

PCBs (Printed Circuit Boards) A product made in the process of processing and connecting materials in a manufacturing plant is subjected to various physical shocks. In particular, when a physical impact that adversely affects the product during the process of moving between the associated processes occurs, the yield may be lowered.

As shown in Fig. 8, there is a type of defect caused by handling, which is a representative defect that can be caused by a physical impact applied to the product.

When the products move from one process to another, friction occurs between the products due to shaking in the tray. At this time, circuit scratching, opening (open), and shorting (short) occur as scratches occur in the surface, as can be seen from the defect shown in Fig. This is referred to as failure due to handling.

Fig. 1 shows a build-up PCB manufacturing process, and Fig. 2 shows a detailed process in a lamination process.

As can be seen in FIG. 1, it can be seen that frequent inter-process movement is required in the manufacture of PCB products. Further, as shown in FIG. 2, more movement is required if each of the in-process sub-processes is included as in the case of the lamination process.

This is because there are a large number of cases where physical shocks can occur during the movement between processes.

When a product is moved, many products are loaded and moved. When an impact is applied in a state where the product and the product are overlapped, the product moves and friction occurs between the products. This can be the main cause of poor handling.

Figures 3-5 illustrate a conventional product transfer method.

Conventionally, as shown in FIG. 3, a bogie is used when the product is transferred to the next process after the completion of the process. In the case of loading by truck, the operator manually loaded the truck on the conveyance truck, but the possibility of handling failure due to unstable loading form during passive loading was high.

To improve this, a method of automatically loading a box-type tray in a loading facility as shown in FIG. 4 is applied.

In addition, as shown in FIG. 5, a loader and a unloader are also applied to a horizontal loading device capable of loading trays.

FIG. 6 shows the operation state of the conventional manual loading method and the present automatic loading method.

As shown in FIG. 6, the present working method does not cause the operator to touch the product directly, thereby causing no friction between the products due to the carelessness of the operator.

However, using a stacking tray does not mean that the product will not be completely impacted.

Fig. 7 shows a state in which the product is shaken inside the tray.

Because the size of each model is different, there is a gap between the product loaded on the tray and the wall of the tray enough to move the product. As a result, as shown in FIG. 7, when the product moves in the tray, the product is shaken in the tray, thereby causing friction between the products. As a result, A means for limiting the movement of the product is required.

A method of making a dedicated tray suitable for the size of the model may be considered in order to prevent the product loaded in the tray from shaking.

However, this method has a disadvantage in that it requires not only an increase in manufacturing cost because a dedicated tray is provided for each model, but also a process of sorting and storing a dedicated tray for each model is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an improved stacking tray capable of preventing shaking of a product contained therein even when moving.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The problem when using the box type stacking tray that does not have direct contact with the operator during the automatic loading and transferring of the product is that the product size is different for each of the existing products and that it is time-consuming and costly The size of the stacking tray that can be used for general purposes is made larger than the size of the product to be supplied. However, as shown in FIG. 7, when shake occurs in the product inside the tray when the bogie is moved, the handling error such as the surface scratched is exposed.

The tray according to the present invention improves this problem by providing a fixture that can be fixed according to the size of the product.

- Example 1

FIG. 9 shows a first embodiment of a tray according to the present invention, in which a variable fixing jig is installed in a unidirectional manner.

9, the first fixing frame 106, which is formed by arranging the long holes 102a and 102b side by side on both side walls 100a and 100b facing each other of the tray 100 and fixed by the butterfly nuts 104a and 104b, As shown in Fig. The first fixed frame 106 is installed across the tray 100 in the left and right direction, and both ends of the upper end of the frame are elongated and inserted into the slots 102a and 102b.

After the butterfly nuts 104a and 104b are loosened, the position of the first fixing frame 106 is adjusted according to the loaded product 200. Thereafter, the butterfly nets 104a and 104b are tightened to fix the first fixing frame 106. [ It is preferable that the first fixing frame 106 is of a plate type having a depth corresponding to the depth of the storage space inside the tray 100.

As a result, the flow of the product in the front-back direction of the tray 100 is prevented.

However, since the product can still flow in the direction (left-right direction) in which the first fixing frame 106 is not installed, it is necessary to provide a fixture for preventing the flow of the product in the front / back / left / right direction at the same time.

However, if another fixed body of the same type as that of the first fixed body 106 shown in FIG. 9 is used, each of the fixed bodies 106 and 106 - And it is difficult to fix due to limited movement. Therefore, the shape is designed to be easy to install and move.

- Example 2

Fig. 11 shows a second embodiment of the tray according to the present invention, showing an improved form of the variable fixing jig in the up / down / left / right directions.

In the A-type shown on the left side, the insertion groove 106a is pierced on the upper surface of the first fixing frame 106 at regular intervals, and the second fixing frame 108 for restricting the movement in the left-right direction is inserted into the insertion groove 106a In a fixed manner. In this method, it is easy to apply because it is easy to attach / detach, but it can be applied only to the standardized size.

On the other hand, in the B-type shown on the right side, the third fixing frame 110 is provided by piercing the second long hole 106b in the left and right direction on the frame of the first fixing frame 106 to facilitate the movement of the third fixing frame 110 It is a measure.

The long holes 102c and 102d are also arranged so as to be able to be fixed by the butterfly screws 114a and 114b in parallel with the opposite side walls of the tray 100 in the front and rear direction.

First, after the butterfly nuts 104a and 104b are loosened, the position of the first fixing frame 106 is adjusted according to the loaded product 200. Thereafter, the butterfly nets 104a and 104b are tightened to fix the first fixing frame 106. [

Next, after the butterfly nuts 114a and 114b are loosened, the position of the third fixing tool 110 is adjusted according to the loaded article 200. Then, the butterfly nets 114a and 114b are tightened to fix the third fixing frame 110. [

If this method is used, there is an advantage that it can be easily fixed even if a product of a certain size is loaded. However, there is a disadvantage that the initial jig processing ratio is higher than that of the A-type.

However, it was possible to prevent the flow of the product by fixing the fixed type B-type fixture at the same time on both sides.

- Example 3

FIG. 12 illustrates a third embodiment of a tray according to the present invention, in which a rubber packing is applied in order to alleviate an impact generated when a fixed frame is used. Generally, in the long holes 102 (102a to 102d) where the fixed molds 106 and 110 made of a hard material move, abrasion occurs due to continuous friction, and the foreign matter generated at this time may act as a cause of failure.

In order to prevent this, a rubber packing 116 is applied to the slot 102 to reinforce the tray material so as to prevent foreign matter from being worn out. In addition, it is preferable that a sponge (not shown) is provided at the product contacting portion in the fixed frames 106 and 110 so as to alleviate the physical impact due to the direct contact between the fixed frames 106 and 110 and the product 200.
