Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a metal mask plate frame when cream solder is printed on a printed wiring board or the like.

[0002]

[Prior Art]

 As shown in FIG. 5, a conventional cream solder printing plate frame is composed of a plate frame 1, a silk screen 2, a metal mask 3 and an adhesive tape 4, and as shown in FIG. The metal mask 3 is located at the center of the back surface of the silk screen 2, and the outer periphery of the metal mask 3 is bonded to the silk screen 2 with a constant width.

[0003]

[Problems to be solved by the device]

 However, in the conventional configuration described above, although the productivity is excellent in that a general-purpose silk screen plate frame can be used, the metal mask 3 is adhered and fixed to the silk screen 2, so that the metal mask 3 portion is not fixed. When a change occurs, it is not possible to replace only the metal mask, so it was necessary to manufacture a new general-purpose silk screen printing frame each time.

In view of the above problems, the present invention aims to provide an easy-to-handle plate frame in which only a metal mask can be replaced.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a plate frame 1 having a frame 1a provided with two fasteners 7, a frame 1b, and a frame 1c provided with a rectangular guide hole 17 at the center near the ends. And 1d.

A movable angle 6 is provided near the frame 1a in parallel with the frame 1a, and a fixed angle 5 is provided near the frame 1b in parallel with the frame 1b.

The movable angle 6 slides horizontally in the guide hole 17 by inserting the guide pins 16 planted at both ends into the guide hole 17.

Both ends of the fixed angle 5 are fixed to the frame 1c and the frame 1d.

Both ends of the metal mask 3 are sandwiched between the fixed angle 5 and the movable angle 6, and the two fasteners 7 provided on the frame 1 a are locked to the claws 8 provided on the movable angle 6, and the fastener 7 is tightened. As a result, the movable angle 6 is pulled in the direction of the fastener 7, and the metal mask 3 is fixed to the plate frame 1 with appropriate tension.

[0010]

[Action]

 The cream solder printing plate frame of the present invention having the above-described structure can be attached by sandwiching one end of the metal mask with the fixed angle and also with the multiple ends similarly sandwiched with the movable angle.

Next, when two fasteners provided on the plate frame are respectively hooked and fastened to the two claws provided on the movable angle, the movable angle is pulled toward the fastener and slides, so that the metal mask is appropriate. Tension is applied and set.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a cream solder printing plate frame according to the present invention.

FIG. 2 is a bottom view, FIG. 3 is an enlarged view of an A portion of the bottom view, and FIG. 4 is an enlarged view of the A portion as viewed from the B direction.

The plate frame 1 is composed of a frame 1a provided with two fasteners 7, a frame 1b, and four fixed frames 1c and 1d provided with rectangular guide holes 17 penetrating near the ends.

As shown in FIG. 1, a movable angle 6 having the structure described below is provided in the vicinity of the frame 1a in parallel with the frame 1a.

Guide pins 16 are provided at both ends of the movable angle 6 and are inserted through guide holes 17 provided in the frames 1c and 1d, and the movable angle 6 is slidably attached.

Further, a plurality of pins 20 are planted perpendicularly to the inclined surface 10 of the movable angle 6 (FIG. 3).

As shown in FIG. 4, the pins 20 are planted so that they do not protrude from the horizontal plane of the metal mask 3.

The fixed plate 22b of the spring-loaded hinge 22 is attached to the side surface 9 of the movable angle 6 by a plurality of screws 21, and the hole 24 provided in the holding plate 22a of the spring-loaded hinge 22 is inserted into the pin 20 to press it. The plate 22a is attached so that the inclined surface 10 is constantly pressed by the restoring force of the spring.

The movable angle 6 is provided with a claw 8 at a position facing the fastener 7, and the fastener 7 is hooked.

Next, a fixed angle 5 having the structure described below is provided in the vicinity of the frame 1b in parallel with the frame 1b.

Similar to the movable angle 6, a plurality of pins 20 are vertically planted on the inclined surface 10. The height of the pin 20 is such that it does not protrude from the horizontal plane of the metal mask.

Similarly, when the fixing plate 22b of the spring hinge 22 is attached to the side surface with the plurality of screws 21, the holding plate 22a of the spring hinge 22 constantly presses the inclined surface 10.

In order to set the metal mask 3 on the plate frame 1 described above, the holding plate 22a of the hinge with spring 22 attached to the fixed angle 5 is raised, and a plurality of fixing members provided at one end of the metal mask 3 are fixed. The holes 23 are inserted into the pins 20.

When the holding plate 22a is released, its restoring force causes the metal mask 3 to be pressed and fixed by the holding plate 22a.

Similarly, a plurality of fixing holes 23 provided on the other end of the metal mask 3 are inserted into a plurality of pins 20 provided on the movable angle 6, and when the holding plate 22a is released, the restoring force is generated. Thus, the metal mask 3 is pressed and fixed by the pressing plate 22a.

Next, when the fastener 7 is hooked on the claw 8 provided on the movable angle 6 and tightened, the guide pin 16 of the movable angle 6 slides toward the frame 1 a side within the range of the guide hole 17, and the metal mask 3 is appropriately moved. Tension is applied and fixed to the plate frame 1.

[0029]

[Effect of the device]

 As is apparent from the above embodiment, the present invention allows various metal masks to be attached to and detached from one plate frame. Therefore, only one plate frame is manufactured, and the metal mask is manufactured each time when necessary. Since it can be set to, it is not necessary to manufacture the whole plate frame, which facilitates manufacturing.

After using the plate frame, if the metal mask is removed from the plate frame and the plate frame and the metal mask are stored separately, even if the number of types of metal masks increases, only one plate frame is required, only the metal mask. Since it suffices to store, the storage space is significantly reduced.
