Such a screen printer includes a conveyor for transferring a printed circuit board to a work section, a clamping device for fixing the transferred printed circuit board, a position error between the clamped printed circuit board and a metal mask for cream solder printing An alignment device for correcting the position of the printed circuit board with the calculated error, a vertical transfer device for transferring and aligning the aligned printed circuit board to the bottom surface of the mask provided at the upper part, A squeegee for putting the cream solder placed on the surface of the mask having the input hole corresponding to each contact space of the printed circuit board into each contact space of the printed circuit board; An unloading field for transferring the separated printed circuit board to the next process, Etc. The

Such a screen printer moves a printed circuit board through a conveyor to a working position and adjusts the position of the printed circuit board by confirming the position of the recognition mark provided on the printed circuit board and the position of the recognition mask provided on the printed circuit board with a camera. Thus, after the respective injection holes of the mask are precisely aligned on the upper portions of the respective contact spaces of the printed circuit board, the work conveyor is brought into contact with the contact space of the printed circuit board at the lower portions of the respective injection holes of the mask. Then, the cream solder, which is located at one side of the surface of the mask, is passed through each of the injection holes of the mask pattern by moving the squeegee forward and backward so that the cream solder falling down into each of the injection holes of the mask can be applied to each contact space of the printed circuit board It will be. In the screen printer for mounting a printed circuit board surface, a conveyor for conveying a printed circuit board is divided into an input portion, a center portion, and a discharge portion. The printed circuit board inserted through the input portion conveyor is moved to the center portion conveyor, After the cream solder application on the conveyor, the printed circuit board is discharged to the outside through the discharge conveyor.

Referring to FIG. 10, the printed circuit board P conveyed to the center conveyor 10 through the input conveyor is stopped at the center of the center conveyor by the sensor and the circular plate, and is fixed by the clamping device. After the vision camera confirms the recognition mark of the printed circuit board and the recognition mark of the mask plate M, the recognition mark positions of the printed circuit board and the mask plate are matched. The center conveyor rises to closely contact the mask plate with the printed circuit board and also supports the mask plate so that the mask plate is not pushed downward by the down pressure of the squeegee S when the cream solder is applied. The squeegee blade N is lowered by the cylinder C and the cream solder placed on one side of the mask plate is applied to the printed circuit board through the patterned openings of the mask plate while the squeegees move back and forth. When the screen printing process is finished, the center conveyor descends and separates the printed circuit board from the mask plate. At this time, when the center conveyor supporting the mask plate is lowered, the squeegee presses the mask plate by the residual air pressure of the cylinder and the tensile force of the squeegee blade pressing the mask plate, and the mask plate is subjected to uneven force, The mask plate having the warping changes the shape or position of the printed cream solder on the printed circuit board and the residual cream solder in the opening of the mask plate due to the increase in frictional force between the mask plate and the cream solder, . This causes an insufficient amount of cream solder to be printed on the printed circuit board or causes a position error and causes clogging of the opening of the mask plate.

First, the conveyor unit 100 can support the mask plate M, and the printed circuit board P can be drawn in and discharged, and the size of the printed circuit board P can be adjusted according to the printed circuit board P.

The conveyor unit 100 includes a pair of front conveyors 120 and a rear conveyor 140 having a constant horizontal level so as to support the mask plate M. [

A front conveyor 120 for supporting a lower side of the mask plate M and an LM guide guided and moved on a screw shaft rotated by motor power of the front conveyor 120 and the gap adjusting device, And a rear conveyor 140 which is moved forward and backward to the front conveyor 120 and is spaced apart from the printed circuit board so as to correspond to the width of the printed circuit board to support the other side of the lower surface of the mask plate M.

A conveyor belt 160 connected to the rollers is installed inside the front and rear conveyors 120 and 140 so that the printed circuit board P is drawn between the front and rear conveyors 120 and 140 by motor rotation, And then discharged.

Here, the fixing block 180 may be protruded at regular intervals so that slots formed in the concave-cut shapes at the inner ends of the front and rear conveyors 120 and 140 are formed at regular intervals. So that the steel guide 340 is provided with a space in which the steel guide 340 is raised.

The backup unit 200 is configured to allow the printed circuit board to be raised or lowered.

The backup unit 200 includes a table 220 installed at a lower portion of the conveyor unit 100, a backup plate 240 fixed to the table 220, And a backup pin 260 that can support the lower surface of the printed circuit board when it rises.

The clamping unit 300 includes an inner plate 320 installed on the inside of the front and rear conveyors so as to be movable up and down respectively, And a steel guide (340) which is in close contact with both ends of the printed circuit board located therebetween when moved to the front conveyor side by operation. The configuration of the clamping unit 300 is shown in detail in FIGS.

Fig. 4 is a perspective view of the conveyor unit, Fig. 5 is a rear view of the rear conveyor, and Fig. 6 is an enlarged view of the inner plate and the steel guide.

Referring to FIGS. 4, 5 and 6, the inner plate 320 is formed as a vertical plate in a shape of a letter A, and the upper portion is formed as a horizontal plate in a vertically bent shape at an upper end of the vertical plate.

Referring to FIGS. 7 and 8, the connecting unit 400 is connected to the clamping unit, that is, the steel guide, so as to be fixed or lowered in conjunction with the operation of the backup unit 200, .

The connection unit 400 is interlocked with the falling of the backup plate to connect / disconnect the inner plate and the backup plate.

And is connected to the operation of the backup plate. When the clamping unit 300 is lifted up, the printed circuit board is fixed to the lower portion of the mask plate by a steel guide, so that a screen printing operation is performed. The backup plate is lowered and the interlocking unit interlocked is interlocked to lower the inner plate of the clamping unit 300 so that the printed circuit board can be separated from the mask plate.

When the rod is moved backward, the inner plate and the connection unit are connected by the circular plate attached with the rod, so that the connection unit and the inner plate interlock with each other when the backup plate is lowered .

The reason why the printed circuit board is separated from the mask plate before the center conveyor is lowered in the printing process is that when the center conveyor is lowered while the printed circuit board is in close contact with the mask plate, A tensile force of the blade is generated and the squeegee presses the mask plate by the residual air pressure of the cylinder, so that the mask plate is warped and the printed circuit board is affected by the warping of the mask plate and the cream solder applied to the printed circuit board is deformed And the residual solder may be generated on the mask plate after printing. This causes deterioration of the print quality, so that the printed circuit board is separated from the mask plate before the center conveyor falls.

Fig. 9 (a) is a perspective view of the connecting unit, Fig. 9 (b) is a front view of the cylinder, and Fig. 9 (c) is a rear view of the cylinder.

The connecting unit 400 is provided between the backup plate and the steel guide to support the steel guide when the backup plate is lifted so that the printed circuit board is supported by the mask plate 400. [ A lower engaging member 440 connected to the upper engaging member and positioned at a lower portion of the backup plate and hooked by a lowering member, A cylinder (460) for lowering the steel guide of the clamping unit when the upper engaging member is brought into close contact with or spaced from the inner plate by a backward operation so that the printed circuit board is separated from the mask plate by the backup plate, . ≪ / RTI >

The upper latching member 420 includes a horizontal axis 422 and a circular plate coupled to the horizontal axis and having an upper end capable of being in tight contact with the steel guide, And a bearing 426 coupled to the horizontal shaft and being in contact with the backup plate. The U-shaped support 424 can be closely contacted with the steel guide.

The upper latching member 420 and the lower latching member 440 are connected to each other by a damper 480 that mitigates an impact when moving up and down by a backup plate.

The reason why the printed circuit board is separated from the mask plate before the center conveyor (in the present invention, the screen printed-circuit board separating apparatus for a screen printer) descends in the printing process is that the center- When the pressure is lowered, the squeegee blade pressing force on the mask plate is generated and the squeegee presses the mask plate due to the residual air pressure of the cylinder, causing the mask plate to warp and the printed circuit board The solder applied to the printed circuit board may be deformed and the residual solder may be generated on the mask plate after printing, which causes the printing quality to be degraded, so that the printed circuit board is removed from the mask plate First, remove it. Therefore, according to the present invention, the clamping unit clamps the printed circuit board to the mask plate by the connecting unit and the cylinder which are operated by the interlocking operation of the backup plate, and the printed circuit board is moved in the vertical direction To separate the coated cream solder on the printed circuit board regardless of the warping of the mask plate to maintain the roundness of the cream solder applied to the printed circuit board and reduce the amount of residual solder in the mask plate openings to reduce clogging, There is an advantage that quality is improved.

It will be understood by those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Of course, many other variations are possible.
