Description

Loading device for printed circuit board

The present invention relates to a printed circuit board stacking device, and more particularly, the stacking is made without contacting each other and other printed circuit boards loaded on the upper surface of the stacking box and the printed circuit board by alternating alternately. The present invention relates to a printed circuit board mounting apparatus capable of preventing damage to a circuit pattern formed on a printed circuit board.

In general, a printed circuit board (PCB) serves to easily connect various electronic devices according to a predetermined frame, and is widely used in all electronic products from home appliances to advanced communication devices. It is classified into general PCB, package PCB, etc.

The printed circuit board is formed by attaching a thin plate such as copper to one side of a phenolic resin insulating plate or an epoxy resin insulating plate, and then etching it according to the wiring pattern of the circuit to form a necessary circuit and punching holes for attaching and mounting components. According to the number of wiring circuit surfaces, the substrates are classified into single-sided boards, double-sided boards, and multilayer boards.

In addition, as the number of layers of the substrate increases, the mounting performance of the component is excellent, and thus it is adopted to high precision products. In recent years, the ultra-thin printed circuit board is widely used due to the development of the electronic industry.

When such a printed circuit board is completed, it is used while being transported in a box for each size in an inspection process or a final assembly process.

As described above, frequent process-to-process movements are required during the manufacturing of the above-described printed circuit board products, and as a result, physical shocks occur, thereby causing friction between the products, which is the main cause of poor handling.

Recently, in order to lower the handling failure rate, a box-type tray is applied to automatically load a printed circuit board in a loading facility.

However, the use of a boxed stacking tray does not mean that the product will not have a physical impact.

That is, since the box-type stacking trays have different sizes for each model, a gap between the products loaded in the trays and the tray walls may be sufficiently moved.

As a result, the product is shaken in the tray as it moves, and as a result, friction between the products occurs, resulting in scratches or poor handling, which in turn may cause the product loaded inside the tray to not shake. It may be considered to make and use a dedicated tray.

However, this method has a disadvantage in that an additional management cost is generated because the manufacturing cost is increased because a dedicated tray is provided for each model, and a process of classifying and storing the dedicated tray for each model is required.

In view of this, Patent Application No. 10-2015-0016207 discloses a box-type tray for loading a printed circuit board product.

Looking at the conventional box-shaped tray for loading a conventional printed circuit board product, in a box type tray (ray-type tray) that forms an inner space for accommodating a printed circuit board (PCB) product, in the left and right directions of the tray First fixing holes extending in the front-rear direction on both side walls facing each other, the first fixing frame coupled to the first long hole and extending in the left and right directions of the tray, and the first fixing means for fixing the first fixing frame. And a second long hole extending in the left and right directions in the first fixing frame, and installing third long holes extending in the left and right directions side by side on both sidewalls in the vertical direction facing each other in the front and rear directions of the tray. A third fixing frame coupled to the long hole and the third long hole and extending in the front-rear direction of the tray, and second fixing means for fixing the third fixing frame, wherein Both ends of the first fixing frame and the third fixing frame are provided with butterfly screws as the first fixing means and the second fixing means, and the side walls of the tray and the first fixing frame and the third fixing member are tightened by tightening the butterfly screws. Each fixing frame is fixed to the side wall of the tray, and by adjusting the position of the first fixing frame to the size of the front and rear direction of the PCB product, the PCB product is prevented from flowing in the front and rear directions and the position of the third fixing frame is adjusted. It is configured to prevent the PCB product from flowing in the left and right direction by adjusting to the left and right size of the PCB product.

However, the conventional conventional box-shaped tray for loading a printed circuit board product configured as described above has a first fixing frame, a first fixing means for fixing the first fixing frame, and a third fixing frame and the third fixing frame as described above. Although the printed circuit boards loaded by the second fixing means may be prevented from shaking, there is a disadvantage in that the printed circuit boards loaded may not be prevented from being damaged due to contact with each other.
