Description
Technical Field
The utility model relates to a screen printing frame position control device especially relates to a piezoceramics piece electrode thick liquids screen printing frame combination adjusting device, belongs to screen printing equipment auxiliary device.
Background
The screen printing frame is often displaced in the process of printing the electrode paste on the surface of the piezoelectric ceramic piece, so that the electrode paste printing layer is easily deviated from the central position of the ceramic piece, and therefore, the screen printing frame needs to be adjusted to ensure that the center of the electrode paste printing layer is coincided with the center of the ceramic piece. At present, the position of the hammer is usually adjusted by knocking the screen printing frame. The following disadvantages exist:
1) the screen printing frame can generate micro deformation due to vibration, so that patterns on a screen are deformed due to the change of the tension of the screen, and the surface of the piezoelectric ceramic piece is printed with defects; in severe cases, the wire mesh is also damaged.
2) The distance required to be adjusted is only hundreds of microns, and the force for knocking the control hammer is difficult to control, so that the displacement generated by knocking is difficult to control, and the adjustment difficulty is high.
Disclosure of Invention
The above-mentioned defect to prior art exists, the utility model aims at providing an adjust and change convenient piezoceramics piece electrode thick liquids screen printing frame combination adjusting device of screen printing frame.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the screen printing frame comprises a screen printing frame mounting rack, a positioning and adjusting mechanism and a locking mechanism; the screen printing frame mounting frame is composed of two channel steel-shaped screen frame clamping strips, wherein the side surface of one screen frame clamping strip is provided with four first mounting screw holes, and the surface of the other screen frame clamping strip is provided with four second mounting screw holes; the positioning adjusting mechanism is composed of two first adjusting screws respectively fixed on the side surfaces of the screen frame clamping strips, two baffle plates respectively fixed in the grooves of the screen frame clamping strips, and second adjusting screws respectively fixed on the baffle plates; the locking mechanism is composed of two compression screws which are respectively fixed on the surfaces of the screen frame clamping strips.
The inner surface of each screen frame clamping strip groove is provided with two slots, and each baffle is embedded in the corresponding slot.
Compared with the prior art, the utility model discloses owing to adopted above-mentioned technical scheme, consequently have following advantage:
1) for the screen printing frame mounting frame with the fixed structure, the screen printing frame mounting frame adopts a combined structure formed by two screen frame clamping strips, so that the screen printing frame mounting frame can adapt to screen printing frames with different specifications.
2) All be provided with adjusting screw at the side and the both ends face of each screen frame card strip, consequently can finely tune the position of screen printing frame in four directions in the front, back, left and right to the position of screen printing frame can accurate regulation screen printing frame. Not only improves the working efficiency and reduces the labor intensity, but also can avoid the defect that the screen printing frame deforms due to knocking vibration, thereby improving the printing quality and prolonging the service life of the screen printing.
3) Each baffle is movably embedded in the corresponding slot, so that the screen printing frame is convenient to replace.
Drawings
Fig. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic structural view of the net frame clip strip of the present invention;
fig. 3 is a sectional view a-a in fig. 2.
In the figure: the screen printing device comprises a first mounting screw hole 1, a first adjusting screw 2, a screen frame clamping strip 3, a baffle plate 4, a second adjusting screw 5, a compression screw 6, a second mounting screw hole 7, a screen printing frame 8 and a slot 9.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3: the screen printing frame mounting frame is composed of two screen frame clamping strips 3 which are of channel steel-shaped structures and are oppositely arranged in the direction of a groove opening, wherein the side surface of one screen frame clamping strip 3 is provided with four first mounting screw holes 1, and the surface of the other screen frame clamping strip 3 is provided with four second mounting screw holes 7. Each screen frame clamping strip 3 is provided with a positioning adjusting mechanism, and the positioning adjusting mechanism is composed of two first adjusting screws 2 respectively fixed on the side surfaces of the screen frame clamping strips 3, two baffle plates 4 respectively fixed in the grooves of the screen frame clamping strips 3, and second adjusting screws 5 respectively fixed on the baffle plates 4. Each screen frame clamping strip 3 is provided with a locking mechanism which is composed of two compression screws 6 respectively fixed on the surface of each screen frame clamping strip 3.
In order to facilitate the installation and adjustment of the screen printing frame 8, the inner surface of the groove of each screen frame clamping strip 3 is provided with a slot 9 at the position close to the two ends, and each baffle 4 is embedded in the corresponding slot 9.
When the screen frame clamping strip fixing device is used, the two screen frame clamping strips 3 are respectively fixed on a printing station of a pulp printing machine (not shown in the figure) through the first mounting screw holes 1 and the second mounting screw holes 7, so that the notches of the grooves of the two screen frame clamping strips 3 are oppositely arranged. The screen printing frame 8 is inserted into the grooves of the two screen frame clamping strips 3 from one end of the two screen frame clamping strips, and then the four stop blocks 4 are correspondingly inserted into the slots 9 of the screen frame clamping strips 3 respectively. And then adjusting the front, back, left and right positions of the screen printing frame 8 by the first adjusting screw 2 and the second adjusting screw 5 until the center of a printing pattern on a printing screen (not shown in the figure) is aligned with the center of a piezoelectric ceramic piece (not shown in the figure), and finally pressing the screen printing frame 8 by the compression screws 6 on the screen frame clamping strips 3 respectively.
When the screen printing frames 8 with different patterns or different specifications need to be replaced, the stop blocks 4 only need to be pulled out of the slots 9, and then the screen printing frames 8 are pulled out of the grooves of the two screen frame clamping strips 3, so that the replacement is convenient and quick, and the screen printing frame mounting frame does not need to be detached.
