Description

WORK DEPOSITING JIG AND SCREEN PRINTING MACHINE}

The present invention relates to a workpiece loading jig for loading a workpiece. In particular, it relates to a workpiece loading jig for suction-fixing a workpiece printed by a screen printing machine to a table.

34 is a perspective view of a screen printing machine.

35 is a schematic side view of a screen printing machine.

36 is a schematic plan view of a screen printing machine.

In Fig. 34, 101 is a screen printing machine, 102 is a base of a screen printing machine, 103 is a movable table attached to be movable, 104 is a guide rail for guiding movement of the moving table, 105 is an operation box of a screen printing machine, and 107 is operation. The operation switch 109 attached to the box is a printing unit which performs screen printing on the workpiece placed on the moving table 103.

35 and 36, 110 is a workpiece mounted on the moving table 103, 200 is a screen plate, 201 is a screen frame of the screen plate 200, 211 is a screen attached to the screen plate 200 , 106 denotes a slider which holds the squeegee 111 and a scraper (not shown), and slides in the direction of arrow A and arrow through hole diameter D, and 108 denotes a frame for sliding the slider 106.

The moving table 103 is attached to slide left and right along the guide rail 104 attached to the base 102. When the movement table 103 moves to the lower portion of the printing unit 109, the movement table 103 is restrained by a stopper (not shown), and the screen printing is performed on the work piece 110 by the printing unit 109. .

The moving table 103 is provided with the suction hole 190, and as shown by an arrow, it has a structure which the workpiece 110 can adsorb | suck to the moving table 103 by sucking air.

When the moving table 103 of the conventional screen printing machine is provided with a suction hole 190 and is intended to suck the work 110, the work 110 can be made of a soft material, or if it is thin, As shown in 37, unevenness may generate | occur | produce on the surface of the workpiece | work 110 in some cases. As described above, there is a problem that printing is not performed correctly when the surface of the work piece 110 has an ups and downs.

38, the through hole 191 may exist in the workpiece | work 110 as shown in FIG. The through hole 191 is a through hole penetrating from the surface of the workpiece 110 to the back surface as shown in FIG. When printing is performed by matching the position of the through hole 191 with the position of the suction table 190 of the moving table 103, the ink 199 is sucked from the suction hole 190 and the back surface of the work piece 110 is removed. There was a problem that would be dirty.

When printing is made to fill the through hole 191 by the ink 199, the through hole 191 is sucked through the suction hole 190 and the through hole 191 is drawn by the ink 199. The problem of not charging occurs.

40 shows a case in which suction is actively used when the ink 199 is filled in the through hole 191 of the workpiece 110. The workpiece 110 is supported by the vinyl chloride plate 197 and the post 196. The ink 199 is easily filled in the through hole 191 by sucking air as shown by the arrow.

The problem to be solved by the present invention is as shown in Fig. 40, except for the case where the ink 199 is filled in the through-hole 191 using the suction of air actively. When the ink 199 is high in viscosity, the through hole 191 can be easily filled with the ink 199 using a suction method as shown in FIG. However, when the viscosity of the ink 199 is low, a problem arises that the ink 199 passes through the through hole 191 or falls by aspiration.

The present invention is adapted to the case where a technique for filling ink is not available by suctioning as described above. That is, as shown in FIG. 39, when the through hole 191 and the suction hole 191 are at the same position or at a very close position, the ink 199 sucks down to the suction hole 190. It is to prevent it from becoming or to dirty the back surface of the workpiece 190.

Figures 41 and 42 illustrate other problems of conventional work piece printing. In particular, it is a figure which shows the problem of the back printing of a workpiece | work.

In the state where the ink 199 is printed on the surface of the work piece 110, the surface on which the ink 199 is printed may touch the moving table 103 to print the back surface of the work piece 110. When the ink 199 is printed on the back side of the work 110 in a semi-dry or less dry state and peels off the work, there is a problem that the ink 199 is less likely to fall due to less dryness or semi-drying. If the workpiece 110 is forcibly peeled off, there is a problem that the residue of the ink 199 remains on the moving table 103 and the surface of the moving table 103 has to be cleaned.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a workpiece loading jig capable of flatly stacking a workpiece on a table surface even when the workpiece is thin or easily bent.

In addition, even if a through hole is present in the workpiece, the present invention can adsorb the workpiece against the table, and at the same time, the workpiece loading jig in which the printed ink drops through the through hole and does not dirty the back surface of the workpiece. The purpose is to get.

Moreover, an object of this invention is to obtain the workpiece loading jig which has a surface from which a workpiece | work is easy to separate.

In addition, an object of the present invention is to obtain a screen printing machine in which the flatness of a work piece, the printing of a work piece with a through hole, or the separation characteristics of the work piece after printing are improved by using the aforementioned various loading jigs.

Embodiment 1.

1 is a perspective view of the workpiece 50, the workpiece loading jig 60, and the table 70.

2 is a perspective view showing a partial cross section of the workpiece loading jig 60.

3 and 4 are side cross-sectional views of the workpiece 50, the workpiece loading jig 60, and the table 70.

The workpiece 50 is, for example, a plastic substrate or a dielectric substrate. The workpiece 50 has a through hole 51. In addition, the workpiece 50 has a positioning hole 52. The table 70 has a suction hole 71. In addition, the table 70 has a positioning pin 72. The workpiece loading jig 60 is a flat plate having a through hole 61. In addition, the workpiece loading jig 60 has a recess 63. As shown in Fig. 2, the through hole 61 penetrates from the surface of the work loading jig 60 to the back surface. The recessed part 63 is a recessed part which does not penetrate to the back surface from the surface of the workpiece loading jig 60.

The workpiece loading jig 60 can be formed of a material such as a steel plate, an iron plate, an aluminum plate, a plastic plate, or a rubber plate. And the through hole 61 can be formed by the etching from both surfaces of the workpiece mounting jig 60. And the recessed part 63 can be formed by the etching from one surface of the workpiece mounting jig 60. Or you may form the through-hole 61 or the recessed part 63 by physical drilling rather than etching. Or you may form by other machining. Or you may form by laser processing.

As shown in FIG. 3, the through hole 61 is provided corresponding to the suction hole 71. As shown in FIG. However, the through holes 61 are not provided corresponding to all the suction holes 71. When the through hole 51 and the suction hole 71 are in the same position, or when the through hole 51 and the suction hole 71 are in the approaching position, the through hole 61 is not provided. That is, the suction hole 71 is blocked by the workpiece loading jig 60.

Thus, when the suction hole 71 exists in the position where the through-hole 51 exists or the position which approached the through-hole 51, the suction hole 71 is occluded by the workpiece loading jig 60. By discarding, the ink 84 printed by the squeegee 111 is sucked by the suction hole 71 and falls out of the suction hole 71, or returns to the rear surface side of the work piece 50, so that the back surface side of the work piece 50 is turned off. You can prevent it from getting dirty.

The recessed part 63 is provided corresponding to the through-hole 51 of the workpiece | work 50. As shown in FIG. The recesses 63 provide a space for allowing the ink 84 filled in the through holes 51 to protrude to the back side of the work piece 50.

As shown in FIG. 4, the recess diameter W is larger than the through hole diameter D. As shown in FIG. The recess diameter W is preferably about 1.5 to 3 times the through hole diameter D. The recess depth V is preferably equal to or larger than the through hole diameter D. FIG. Even when the ink 84 comes out from the back surface of the work piece 50, the shape of the ink 84 indicates a semi-circle due to the surface tension of the ink 84. In order to prevent the semicircular sphere from coming into contact with the inner wall of the recess 63, the larger the diameter of the recess W and the depth of the recess V are better, but the size of the workpiece loading jig 60 is too large. The weakness of) weakens. Therefore, as described above, the recess diameter W is preferably 1.5 to 3 times the through hole diameter D, and the recess depth V is approximately equal to the through hole diameter D.

FIG. 5 shows a case where the work piece 50 is positioned at a position shifted to the right with respect to the work loading jig 60. And the case where the workpiece | work mounting jig 60 is positioned in the position which shifted to the left with respect to the table 70 is shown. Even when the workpiece 50 is shifted and positioned with respect to the workpiece loading jig 60, since the recess diameter W is larger than the through hole diameter D, the ink 84 protruding from the back surface of the workpiece 50 is recessed ( There is no contact with the inner wall of 63). Therefore, the back surface of the work piece 50 is not soiled by the ink 84. And the through-hole 61 shown in FIG. 5 shows the cross section on die shape, and even if the workpiece loading jig 60 is positioned in the position which shifted | deviated with respect to the table 70, the suction hole 71 and The through hole 61 provides a structure in which it is easy to continue.

Although the workpiece 50, the workpiece loading jig 60, and the table 70 are preferably positioned accurately, the problem does not occur even if the positioning is slightly shifted by adopting the above configuration.

6 shows a case where the recesses 63 are continuous. Since the recess diameter W is larger than the through-hole diameter D, the recess 63 may continue.

As a result of the succession of the recesses 63, even when the circle is formed, since the recesses 63 are not through holes penetrating the workpiece loading jig 60, the islands 99 can be left. If the recess 63 is a through hole, the island 99 cannot be present in the workpiece loading jig 60. As shown in Fig. 6, in the case where the through hole 61 is formed inside the island 99, when the recess 63 is the through hole, the suction hole ( 71 is exposed, resulting in the suction force from the suction hole 71 acting on the through hole 51. Therefore, it is preferable that the recessed part 63 is not made into a through hole.

7 shows a case where printing is performed on the work piece 50 on which the circuit pattern 86 is formed.

Since the circuit pattern 86 is formed with respect to the workpiece | work 50, the surface height of the part in which the circuit pattern 86 was formed is higher than the surface or the back surface of the workpiece | work 50 itself.

Thus, when printing with respect to the workpiece | work 50 in which the circuit pattern 86 was formed, it is preferable to provide the through-hole 61 in the part in which the circuit pattern 86 was formed. In Fig. 7, since the through hole 61 shown on the left side is provided in the portion where the circuit pattern 86 does not exist, the suction force from the suction hole 71 is transmitted to the back surface of the work piece 50, The ink 84 may be attracted to the back surface of the work piece 50. In contrast, since the through hole 61 shown on the right side of FIG. 7 is disposed at the portion where the circuit pattern 86 is formed, it is necessary to transfer the suction force from the suction hole 71 to the back side of the work piece 50. none. As shown in the lower right of FIG. 7, the circuit pattern 86 that the through hole 61 contacts is preferably such that the circuit pattern 86 can make contact with the entire through hole 61.

In this embodiment, although the workpiece loading jig 60 in which the recessed part 63 exists is demonstrated, as shown in FIG. 8, even when using the workpiece mounting jig 60 in which the recessed part 63 does not exist, it is used. Does not matter. As shown in Fig. 8, when the viscosity of the ink 84 is high or when the ink 84 does not need to be filled in the entire through hole 51, the recess 63 does not need to exist, and the work You may provide only the through-hole 61 with respect to the mounting jig 60. However, the through holes 61 are not provided for all the suction holes 71, and as described above, when the through holes 51 and the suction holes 71 are in the same position or approached position, the suction holes are provided. The workpiece loading jig 60 is interrupted between the 71 and the through hole 51.

And as shown in FIG. 9, it is good also as a through-hole 61 instead of the recessed part 63 mentioned above. When the number of the through holes 51 is small or the through holes 51 are sparse, as shown in FIG. 6, the islands 99 are not formed by the continuous concave portions 63. In such a case, as shown in FIG. 9, the recessed part 63 may be made into the through hole 61. As shown in FIG.

FIG. 10 shows a case where the elastic layer 88 is provided on the surface of the workpiece loading jig 60. As shown in Fig. 7, if there are irregularities on the back surface of the work piece 50, there is a possibility that a gap is generated between the work piece 50 and the work loading jig 60. An elastic layer 88 is formed on the surface of the workpiece loading jig 60 to prevent air from being sucked out of the gap generated between the workpiece 50 and the workpiece loading jig 60. The elastic layer 88 is provided with respect to the part other than the through-hole 61 or the recessed part 63, ie, the whole planar part of the workpiece loading jig 60. As shown in FIG. The elastic layer 88 can be produced by, for example, applying a photosensitive material to the surface of the workpiece loading jig 60 and irradiating light to form a pattern. Or you may form by screen printing. It is considered that the thickness of the elastic layer 88 is preferably about 30 µm to 100 µm, for example. The elastic layer 88 is not limited to the photosensitive material, and may be other flexible resins or rubbers, and other cushioning materials.

11 shows a case where the elastic layer 88 is formed only around the through hole 61. As shown in FIG.

Since the elastic layer 88 is flexible, the elastic layer 88 can exhibit the suctioning action by suction from the through hole 61.

12 shows a case where the elastic layer 88 is directly provided on the surface of the table 70.

When the elastic layer 88 is formed, the necessary suction hole 71 and the unnecessary suction hole 71 are selected, and the unnecessary suction hole 71 is filled with the elastic layer 88. The suction hole 71 filled by the elastic layer 88 becomes a blocked suction hole 73 and loses suction. In the case of Fig. 12, the work 50 is directly loaded on the table 70. The clogged suction hole 73 is a suction hole 71 at a position corresponding to the through hole 51 of the work piece 50 or at an approaching position. In this case, the elastic layer 88 acts as the work loading jig 60. The elastic layer 88 shown in Fig. 12 can also be formed by a photosensitive material or by screen printing.

FIG. 13 shows a case where the work loading jig 60 is formed of the screen 90 and the screen frame 92. As shown in FIG.

Through-holes 61 and recesses 63 are formed in the screen 90 by removing the photosensitive emulsion. The screen frame 92 is inserted into the screen support 74 as shown in FIG. The surface of the screen support 74 supports the screen 90 on the back side, so that the screen 90 can be flat. Workpiece 50 is loaded onto screen 90.

As shown in Fig. 15, the screen 90 is composed of a screen mesh 94 and a photosensitive emulsion 94.

This screen is the same as that used for screen printing, and the patterning of the photosensitive emulsion 96 can be performed in substantially the same way as the manufacturing method of a screen normally. The portion from which the photosensitive oil 96 is removed from both sides of the screen mesh 94 becomes the through hole 61 as shown in FIG. Moreover, the recessed part 63 is the part from which only one part or part of the screen mesh 94 was removed from the photosensitive oil 96. As shown in FIG.

Embodiment 2.

In this embodiment, the workpiece loading jig which adsorb | sucks the workpiece | work 50 which is easy to bend flatly is demonstrated.

In this embodiment, although the through-hole 51 may exist in the workpiece | work 50, it demonstrates on the assumption that it does not exist.

17 and 18 show a case where the workpiece 50 is sucked using the suction pad 55.

A suction pad 55 is disposed inside the table 70 and sucks the work 50. By moving the suction pad 55 up and down by the air cylinder 56, the suction pad 55 contacts the back surface of the work 50 and then sucks the back surface of the work 50 to press the surface of the table 70. . The suction pad 55 is connected to the pipe 59, and by being sucked by the pipe 59, the suction pad 55 can certainly suck the workpiece. The air cylinder 56 is provided with a pipe 57 and a pipe 58. The rod 54 moves up and down by the inflow of air from the pipe 57 and the pipe 58, and the suction pad ( 55 is able to adhere to the work piece 50.

19, 20, and 21 show a case where the work 50 is adsorbed using the adhesive tape 65. Figs. The adhesive tape 65 is an example of an adhesive material.

The table 70 has an exposed portion 75. The adhesive surface 69 by the adhesive tape 65 is exposed at the exposed part 75. On the other hand, the upper portion of the table 70 is provided with a pressing portion 68 that interlocks up and down. As shown in Fig. 20, the work piece 50 is adsorbed by the pad 64 and conveyed to the upper portion of the table 70. When the work 50 is placed on the surface of the table 70, the work loading jig 60 rises, and the adhesive face 69 adheres to the back of the work 50. As shown in FIG. At the same time, the pressing portion 68 is lowered by the cylinder 45. Thus, the workpiece 50 is sandwiched between the adhesive face 69 and the pressing portion 68. In this way, the adhesive face 69 adheres securely to the work piece 50. Since the height of the adhesive surface 69 is at the same level as the surface of the table 70, the work 50 is laid flat on the surface of the table 70. Printing is preferably performed in the direction in which the adhesive face 69 extends, as shown by arrow P in FIG. This is because the pressure-sensitive adhesive surface 69 is preferably present in the direction of the arrow P in order to prevent the deviation and warpage in the direction of the arrow P because pressure can be applied in the printing direction.

After the end of printing, as shown in Fig. 21, the work loading jig 60 is lowered, and the adhesive surface 69 is separated from the back surface of the work 50. FIG. In this state, the work 50 is carried out. And the adhesive roll 66 and the winding roll 67 rotate by the motor which is not shown in figure, and the new adhesive tape 65 moves to the adhesion surface 69. As shown in FIG. The movement of the adhesive tape 65 does not need to be performed every time of printing, for example, it may be made to move once every 5 times or once every 10 times.

And the vertical movement of the workpiece | work mounting jig 60 is performed by the moving mechanism which is not shown in figure.

22 shows the case where the adhesive faces 69 are arranged in three places.

The place and arrangement direction of the adhesive face 69 may be other than those shown in FIG.

23 and 24 show another example of the workpiece loading jig 60.

In FIG. 23, the case where the adhesive roll 66 which is an example of an adhesive roll is exposed as it is is shown. 24 shows the case where the adhesive tape 65 is exposed through the roller 47. As shown in FIG. In the case of Figs. 23 and 24, although the adhesive tape 65 is in contact with the roller, as shown in Fig. 12, it is preferable to increase the area of the adhesive face 69 in order to increase the adhesive force, and the adhesive face 69 Is preferably a plane.

FIG. 25 shows the case where the adhesive tape 65 is adhered to the entire back surface of the work piece 50.

Since the whole back surface of the workpiece | work 50 is in contact with the adhesive tape 65, and the whole adhesive tape 65 is sucked by the suction hole 71, the workpiece | work 50 can be planar as a whole. And since the suction hole 71 can be made to act on the adhesive tape 65, the workpiece | work 50 can be reliably made to adsorb | suck to the table 70 via the adhesive tape 65 as a result.

Fig. 26 shows a case in which the screen printing machine is provided with the pressing roller 48. Figs.

When the workpiece 50 is not stacked flat, the surface of the workpiece 50 is provided by providing a pressing roller 48 while the table 70 moves to the printing position and applying pressure from the surface of the workpiece 50. It can be flattened. At this time, the work piece loading jig 60 for absorbing the work 50 may be present in the table 70 even though there is no work load loading jig 60 for absorbing the work 50 as shown in FIGS. 17 to 25. In this case, the adsorption degree of the work loading jig 60 and the back surface of the work 50 can be increased by the pressure roller 48.

FIG. 27 shows a case where pressure is applied to the work piece 50 using the adhesive roll 66 instead of the pressure roller 48. As shown in FIG.

The adhesive roll 66 acts as a press roller 48 and exhibits two effects of adsorbing garbage, dust and dust on the surface of the work 50.

And instead of an adhesive tape, you may use an adhesive stick, an adhesive roller, an adhesive paper, an adhesive network, etc. as an adhesive material.

Embodiment 3.

In this embodiment, the workpiece | work mounting jig 60 which the workpiece | work 50 falls easily is demonstrated.

Fig. 28 shows the workpiece loading jig 60 having the unevenness 49 on the surface.

The unevenness 49 can be formed by, for example, Teflon processing on an aluminum plate, an iron plate, or a plastic plate. Alternatively, it may be formed by machining, or may be formed by laser processing. Or you may form using scientific action.

FIG. 29 shows a case where printing is performed using the workpiece loading jig 60 having the unevenness 49.

Since the unevenness 49 is present even when the ink 84 that contacts the workpiece loading jig 60 to the surface is semi-dry or less dry, the unevenness 49 exists, so that the workpiece loading jig 60 and the ink 84 The contact area becomes small. For this reason, as shown in FIG. 30, even when peeling the workpiece | work 50, it peels smoothly, and the ink 84 does not stick or remain on the surface of the workpiece | work mounting jig 60.

31 and 32 show another example of the unevenness 49.

Fig. 31 shows that the unevenness 49 has a wave shape. In the case of Fig. 32, the unevenness 49 shows a square shape. In the case of Figs. 31 and 32, the unevenness 49 is formed in a waveform or a square only in the horizontal direction. However, the shape of a waveform or a square may be formed by crossing the horizontal and vertical directions.

33 shows the case where the unevenness 49 is formed by using a mesh material.

When using a mesh type thing, it is not necessary to form the through hole 61 in particular, and the space between a gap serves as the through hole 61. As shown in FIG. In addition, it is not necessary to form the unevenness 49 in particular. By using the mesh material, the unevenness 49 and the through hole 61 are automatically provided without performing any special processing.

As described above, according to the present invention, even when the through hole 51 is present in the workpiece 50, the through hole 61 of the workpiece loading jig 60 is selective to the suction hole 71 of the table 70. Since the workpiece | work 50 is sucked and fixed reliably, it can prevent that the ink 84 leaks from the through-hole 51 by the suction, and the back surface of the workpiece | work 50 can be prevented.

In addition, according to the present invention, since the workpiece loading jig 60 can be formed into a flat plate in accordance with the size and pattern of the workpiece, the workpiece of various sizes and patterns can be reliably suction-fixed by a simple jig called a flat plate.

Further, according to the present invention, since the workpiece loading jig 60 is formed by a screen used for screen printing, the workpiece loading jig 60 can be easily manufactured.

In addition, according to the present invention, since the workpiece is sucked or adhered by the workpiece loading jig 60, even when printing on a thin workpiece or a soft workpiece that is easily deformed in shape, flatness can be secured and printing can be performed. .

In addition, according to the present invention, since the unevenness 49 is provided on the surface of the workpiece loading jig 60, the workpiece can be easily peeled off.
