Description

Solder Cream Feeder for Screen Printers {SOLDER CREAM SUPPLYING APPARATUS FOR SCREEN PRINTER}

The present invention relates to a solder cream supply device for a screen printer, and more particularly, to a solder cream supply device for a screen printer to enable a quick control while constantly supplying an amount of solder cream supplied to a mask in a screen printer. .

In general, various components and the entire circuit are connected by soldering on the printed circuit board, which is an essential component of an electronic device product, so that each function can be exhibited.

In the case of double-sided mounting of components on a printed circuit board, an insert mounting method and a surface mounting method are used together.Because of technical differences in soldering, a surface mounting method is preceded by an insert mounting method, and then an insert mounting method is applied. The parts are soldered.

At this time, the solder used in the surface mounting method is made of a cream type having a slight viscosity and fluidity because powder solder and liquid flux are mixed at a predetermined ratio.

Therefore, in the case of neglecting management of printing pressure, speed, mast, etc. in the screen printing process, soldering failure occurs.

And with reference to Figures 1 and 2 attached to the operating state of the solder supply device of the conventional screen printer, the solder supply device of the conventional screen printer is to install the mask (1) in the equipment, to proceed with the process After the printed circuit board 2 is inserted, the pads of the circuit board 2 and the opening 1a of the mask 1 are aligned using the image recognition marks of the mask 1 and the circuit board 2. The cream solder 6 is supplied to the surface of the mask 1 using a spatula or the like.

Next, the cream solder (6) in the process of uniformly applying the cream solder (6) to the mask (1) in the opening (1a) by the pressure in the gravity direction of the squeegee (3) and the movement in the straight direction ( 6) is applied in the same pattern as the electronic circuit pattern formed on the printed circuit board 2 through the opening 1a of the mask 1. At this time, the squeegee 3 is moved by the squeegee driver 4.

After the process, the circuit board 2 and the mask 1 may be separated at an appropriate speed and transferred to the insertion mounting process.

However, the conventional screen printer spreads an appropriate amount of cream solder with a spatula for soldering and applies it in arbitrary shape to the surface where the squeegee comes into contact with the mask, so that the cream solder is also included in the sliding movement of the squeegee provided on the upper surface of the mask. There is a problem in that the solder is thickly applied to only one side, while the coating is spread out to the outside of the squeegee while moving, and the other side is not applied, resulting in a defect of the printed circuit board.

In addition, the solder supply device of the conventional screen printer is difficult to quantitatively control the amount of cream solder, and the pressure applied to the opening of the mask is determined by the load on the amount of solder, so that the process conditions vary depending on the amount of solder. In addition, there was a problem in that the precise process conditions can not be executed during the processing of parts requiring high-density mounting.

When the up and down operation of the 50, the magnet sensor bar 120 equipped with a sensor so as to check the amount of solder cream accommodated in the cartridge 200 is mounted, then the main base 40 of the The sensor plate 130 is mounted on one side to detect the height of the magnet sensor bar 120 while guiding it during the up and down operation of the magnet sensor bar 120.

Next, the cover 90 is mounted after mounting the air supply unit 80 that supplies air to the nozzle fixing body 20, the pressurized cylinder 50, and the main fixing ring 20 on the main base 40. The assembly of the solder cream supply device 10 of the screen printer is completed.

Here, assembling order of the solder supply device of the screen printer reveals that it can be configured differently from the above.

Next, look at the state of use of the solder supply device of the screen printer configured as described above are as follows.

First, the cartridge 200 containing the solder cream is mounted on the single fixing ring 70 constituting the solder supply device 10 of the screen printer.

In this case, the cartridge 200 is inserted into the cartridge inserting portion 74 constituting the single fixing ring 70 to support the stepped portion of the cartridge support groove 75 located above the cartridge 200. Will be.

In addition, the magnet sensor bar 120 and the sensor plate 130 to recognize the amount of solder cream accommodated in the cartridge 200.

Next, when an operation signal of the solder supply device 10 of the screen printer is transmitted, the air supply unit 80 supplies air to the nozzle fixing body 20, the pressure cylinder 50, and the main fixing ring 20. do.

In addition, the pressure cylinder 50 is a rod 52 is moved forward in accordance with the pneumatic pressure and the pressure plate 51 mounted on the end of the rod 52 is a solder cream contained in the cartridge 200 Pressurized.

At this time, the magnet sensor bar 120 coupled to the pressing plate 51 delivers the amount of solder cream accommodated in the cartridge 200 in real time while interlocking.

Next, the solder cream discharged from the cartridge 200 by the pressing plate 51 passes through the guide member 104 mounted on the nozzle fixing body 20, and opens and closes the nozzles of the nozzle fixing body 20. 100) and then discharged to the outside to be delivered to the mask.

That is, the solder cream is delivered to the mask while being discharged to the outside when the inlet hole 101b, the through hole 102c, and the outlet hole 103b are located on the same line.

Next, when the solder cream transferred to the mask is blocked in the above state, the sliding member 102 constituting the opening and closing nozzle 100 is slid to operate so that the through hole 102c is the inlet hole 101b. What is necessary is just to arrange | position on the other line of the outlet hole 103b.

At this time, the solder cream located in the sliding member 102 is to be discharged to the outside through the air discharged from the air passage (102d) to solve the problems caused by the residue and sticking of the solder cream.

When the solder cream is to be supplied to the mask again, the sliding member 102 constituting the opening / closing nozzle 100 is slid to operate so that the through hole 102c is formed of the inlet hole 101b and the outlet hole 103b. It can be located on the same line.

Next, if you want to replace the cartridge 200, the solder cream is mounted is to proceed in the reverse order of the mounting of the cartridge 200.

In the above description with reference to the accompanying drawings, the solder supply apparatus of the present invention screen printer mainly described in a specific shape and direction, the present invention can be variously modified and changed by those skilled in the art, such variations and modifications the present invention It should be construed as being included in the scope of the right.
