Problems solved by technology

[0005] (1) After the screen is tensioned, it needs to maintain a certain tension, but if it is used too much, it will produce plastic deformation. Once the deformation is too large, the screen frame will be scrapped; and because the screen installed on the screen needs a certain tension to tension the pattern However, due to the characteristics of the screen, the screen needs to be stored at a room temperature of 20 degrees Celsius, otherwise the screen will lose its tension in about half a year and the screen frame will be scrapped
Therefore, the traditional screen frame needs to be stored in an air-conditioned room, which requires high storage requirements, and the storage warehouse occupies a large area
[0006] (2) A finished screen frame can only be used for one type of PCB printing, and the screen and pattern board cannot be replaced, so the storage of the screen frame takes up a lot of space
[0007] (3) It takes a long time to make the pattern board. The pattern of the PCB board is generally composed of holes. The holes are drilled with a special drilling machine. A pattern of a general size has tens of thousands of holes. It takes a long time to make. Each pattern board is about takes a day to make

Embodiment 1

[0065] see Figure 1 to Figure 3 , a kind of screen printing screen frame of the present embodiment is a screen printing screen frame with one side adjustable, including an adjustable screen printing frame and a pattern plate 30;

[0066] Specifically, the silk screen adjustable frame includes a first frame 11, a second frame 12, a third frame 13, and a fourth frame 14 adjacent in sequence, and the silk screen adjustable frame also includes two first adjustment parts 20 and four pressing plates 40. Two guide columns 51, two fixing screws 52; the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 are combined to form a rectangle; the second frame 12, the third frame 13 and the The fourth frame 14 is fixedly connected, and the second frame 12 , the third frame 13 and the fourth frame 14 can also be set in an integrated manner.

[0067] Specifically, both ends of the first frame 11 are respectively movably connected to one end of the second frame 12 ...

Embodiment 2

[0080] see Figure 1 to Figure 7 The difference between the second embodiment and the first embodiment is that the edge of the pattern plate 30 is not pasted with an adhesive tape layer;

[0081] Specifically, the top surfaces of the first frame 11 and the third frame 13 are provided with a plurality of first positioning pins 15; the pattern plate 30 is provided with a plurality of first holes 31 corresponding to the first positioning pins 15;

[0082] The top surfaces of the second frame 12 and the fourth frame 14 are provided with some second positioning pins 16; the pattern plate 30 is provided with some slotted holes 32 corresponding to the second positioning pins 16, and the length direction of the slotted holes 32 is in line with the The length directions of the second frame 12 or the fourth frame 14 are consistent;

[0083] In this preferred embodiment, the first hole position 31 is a special-shaped hole; the cross-sectional shape of the special-shaped hole is composed...

Embodiment 3

[0087] see Figure 1 to Figure 7 The difference between the third embodiment and the second embodiment is that the top surfaces of the second frame 12 and the fourth frame 14 are not provided with the second positioning pin 16; the pattern plate 30 is not provided with the corresponding second positioning pin 16 The long hole 32;

[0088] Specifically, the edges of the pattern board 30 corresponding to the second frame 12 and the fourth frame 14 are pasted with an adhesive tape layer.

[0089] The working process of this embodiment:

[0090] First, install the pattern board 30 on the silk screen adjustable frame, insert the first positioning pin 15 into the first hole 31, and press the first frame 11 and the third frame by the pressing plate 40 corresponding to the first frame 11 and the third frame 13 The pattern plate 30 on the position 13, and then the edges of the pattern plate 30 corresponding to the second frame 12 and the fourth frame 14 are affixed with an adhesive t...

Abstract

The invention relates to an adjustable screen printing frame and a screen printing screen frame, comprising a first frame, a second frame, a third frame and a fourth frame adjacent in sequence, two first adjusting parts, and several pressing plates; the first frame The two ends are respectively movably connected to one end of the second frame and the fourth frame, and the moving direction of the first frame is consistent with the length direction of the second frame; one of the first adjusting parts connects the first frame and the second frame, and the other An adjusting piece connects the first frame and the fourth frame, and the first adjusting piece is used to adjust the moving distance of the first frame; each pressing plate is connected with the frame, and each pressing plate and the frame jointly press the edge of the pattern plate. The screen printing adjustable frame of the present invention compresses the pattern plate through the pressure plate and the frame together, drives the first frame and an edge of the pattern plate to move through the first adjusting member, and then can tension the pattern plate, even if the pattern plate is deformed. The first adjusting member is adjusted again, thereby re-tensioning the pattern plate.

Description

technical field [0001] The invention relates to the technical field of screen printing production, in particular to an adjustable screen printing frame and a screen printing screen frame. Background technique [0002] The silk screen frame is a printing plate used for screen printing of circuit boards. During printing, the ink is transferred to the holes of the printed circuit board through the holes of the stencil through a certain pressure. [0003] The existing silk screen frame is composed of a frame, a screen, and a pattern plate. The frame is welded by aluminum profiles, and the wire mesh is made by using a tensioning machine to bond the elastic mesh through a fixed tension. The four sides of the frame provide tension for the mesh frame, so the mesh is still maintained after being attached to the basic frame. Tension in four directions, and finally put the pattern plate on the mesh, use glue and adhesive tape to stick the four sides to the screen tightly, and after cu...
