Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention transports a printed wiring board between each processing step in a printed wiring board manufacturing process. The present invention relates to a printed wiring board conveyance device.

(Prior Art) Printed wiring boards are manufactured using a copper-clad laminate, an adhesive-coated laminate, or the like as a substrate through numerous processes such as polishing, etching, and plating.

Traditionally in the manufacturing process of printed wiring boards.

Regarding the mechanization of transportation between printed wiring board manufacturing processes, various studies and improvements have been made, including 9 improvements in workability and 1 improvement in quality.

In this case, 2. Normally, there is a method of manually stacking printed circuit boards that allows receiving, 1fffl transport, and supply with a simple structure and low equipment cost, and a method of stacking printed circuit boards by hand to prevent surface scratches due to stacking. Grooves are created at predetermined intervals and the printed circuit board is inserted into the grooves.

There is a method of using a storage device that can be stored vertically or horizontally.

(Problems to be Solved by the Invention) In the former case, since the printed circuit boards are stacked one on top of the other, there are problems such as misalignment between the printed circuit boards during transportation, damage to the printed circuit board surface due to vibration, and problems such as transfer in a predetermined amount. This required manual labor, which was an obstacle in terms of quality, man-hours, etc.

The latter is advantageous in that compared to the former, the printed circuit boards are brought into contact with each other, and scratches can be prevented, but the equipment cost is high.

There are some drawbacks, such as the limited capacity of the printed circuit board.

The requirements for manual labor such as transfer were the same.

The present invention provides a printed circuit board conveying device that can prevent scratches caused by transferring printed circuit boards and improve production efficiency.

(Means for Solving the Problems) The printer 1-substrate transfer device of the present invention includes a receiving machine 12 which is disposed at the rear end of a first processing machine 9, for example a polishing machine 100, as shown in FIG. 2. and a second processing machine 2, for example, a loading machine 3 disposed at the forefront of the washing machine 101.

In this example, the substrate conveying device to the printer 1 of the present invention is used in the process of polishing the edges of the printed circuit board using a polishing machine and degreasing and cleaning it using a cleaning machine.

In the receiving machine 1, 4 is a transport roll conveyor,
The polished printed circuit board 5 is in a horizontal state.

It is transported on this transport roll conveyor 4. A roll conveyor 6 is provided on a surface slightly below the surface of the transport roll conveyor 4, and a printed circuit board receiving tool 7 is placed on the roll conveyor 6.

This receiving tool 7 includes a receiving plate 8 on which a printed circuit board is placed, a supporting plate 9 that is attached perpendicularly to one end of the receiving plate and supports the printed circuit board on an inclined surface, and a supporting plate 9 that supports the printed circuit board attached to the supporting plate 9. The angle of inclination of the support plate 9 is preferably 5 to 40 degrees. In the case shown in FIG. 1, the angle of inclination is 8 degrees.

The printed circuit boards 5 that have been polished and transported are sequentially transferred to a receiving tool 7.
It is propped up along the inclination of the support plate 9. Receiving tool 7
When a certain amount of printed circuit boards 5 are collected, a receiving tool 7 is moved on a roll conveyor 6 and transferred to a cart 2. The height of the cart 2 is approximately the same as that of the roll conveyor 6, and the cart 2 carrying the printed circuit board 5 is moved to the loading machine 3.

The loading machine 3 has almost the same structure as the receiving machine 1,
11 is a roll conveyor, and 12 is a transport roll conveyor.

The receiving tool 7 on the trolley 2 is transferred to the roll conveyor 11 of the feeding machine 3.
It is placed on top and moved by the roll conveyor 11 to the transport roll conveyor 12 of the loading machine 3.

Here, the printed circuit board 5 is transferred onto a transport roll conveyor 12 and sent to a cleaning machine 101 which is the ninth processing machine.

Details of the printed circuit board receiving tool 7 are shown in FIG. The receiving tool 7 includes a receiving plate 8 on which a printed circuit board is placed, a supporting plate 9° that is attached perpendicularly to one end of the receiving plate and supports the printed circuit board on an inclined surface, and a supporting plate 9 that is attached to the supporting plate 9 to hold the printed circuit board. It consists of a tool 10 and a holder 10.
The U-shaped tip is rotatably fixed to the upper part of the support plate 9. Reference numeral 13 denotes a spring, which draws the printed circuit board 5 by its elasticity and holds and fixes it.

At the stage of placing the printed circuit board 5 on the receiving tool 7, the holder 1
0 is a'3 by raising it to the position shown by the dotted line.

The lengths of both sides of the square shape of the holder 10 are determined according to the thickness of the pudding mill board to be placed on the receiving tool 7.

Since the holder 10 has a U-shape, it can hold and fix printed circuit boards even if the amount of printed circuit boards mounted is small or large. When the amount of printed circuit boards to be loaded is small, it is held at the bottom edge of the printed circuit board, and when there is a large amount, it is held at the top edge.

An elastic roll 14 made of vinyl chloride is attached to the printed circuit board contact portion at the tip of the holder 10 to prevent the printed circuit board from being damaged.

In addition, the printed circuit board is held and fixed securely by preventing it from falling. Furthermore, by coating the receiving plate 8 and the supporting plate 9 with a protective material such as rubber, it is possible to prevent the printed circuit board from slipping and to prevent the receiving plate 8 from being worn out.

FIGS. 3 and 4 show a roll conveyor 12 for conveying the curtain plate 5 to the pudding 1 mounted on the receiving device 7 in the feeding machine 3.
This explains the equipment used to transfer the data.

Reference numeral 15 denotes a suction pad that sucks the lower end of the printed circuit board at the forefront position mounted on the receiving tool 7 and separates the printed circuit board at the forefront position from the others. Reference numeral 16 denotes an air blowing nozzle that blows air in order to reliably separate only one printed circuit board. The length of this air blowing time is varied by a timer or the like depending on the condition of the printed circuit board to be separated. For example, when putting in a wet printed circuit board, the spraying time is increased to ensure separation of the printed circuit board.

Reference numeral 17 denotes a printed circuit board gripping tool having a U-shaped cross section, and grips the lower end of the board 1-1i separated by one.

The printed circuit board is rotated, laid down horizontally, and placed on the transport roll conveyor 12.

1B is a printed circuit board detection sensor installed between 11e and the feeding roll conveyor 12, and if the board gripping tool 17 is rotating quickly and the board detection sensor 18 does not detect the board,
It is determined that there is an abnormality and the printed circuit board insertion operation is performed again.

(Effects of the Invention) In the printer 1-board transfer device of the present invention, the L-shaped receivers 7 holding and mounting printed circuit boards can be easily separated, so the L-shaped receivers 7 can be easily separated without transferring the printed circuit board. The first process begins with the printed circuit board loaded on the receiving tool 7.

Since it can be transferred to the second processing machine, it is possible to prevent scratches from occurring when transferring the printed circuit board, and it does not require a large number of man-hours. In addition, since they can be stacked vertically, they have a large storage capacity and require very little storage space.
