The positioning structure of a special-shaped glass screen printer is an important component to ensure that the glass is accurately and stably positioned in the designated position during the printing process.

[0004] As shown in the above-mentioned prior art, although the special-shaped glass positioning structure in the glass screen printing machine in the prior art can achieve precise positioning of the special-shaped glass by adjusting multiple groups of displacement and extrusion mechanisms one by one, in the prior art, since the spacing of the displacement and extrusion mechanisms is fixed, when encountering a large piece of special-shaped glass, the displacement and extrusion mechanisms do not fully cover the clamping and extrusion of the glass side, and the glass positioning may be unstable. In addition, the bridge in the prior art is set above the glass positioning mechanism, which greatly affects the printing work of the glass.

[0005] Therefore, it is necessary to provide a positioning structure for a special-shaped glass screen printing machine to solve the above technical problems. Utility Model Content

[0038] The displacement extrusion mechanism 18 is symmetrically installed on both sides of the conveying assembly, and multiple displacement extrusion mechanisms are arranged at equal distances.

[0039] The second adjustment assembly is symmetrically mounted above the fixing base 3 and is used to adjust the spacing of the displacement extrusion mechanism 18 on one side;

[0040] The first electric push rod 5 is symmetrically fixed on both sides of the fixed shell 2. A mounting plate 6 is fixed to the output end of the first electric push rod 5. The mounting plate 6 is slidably connected to the base plate 1, and the mounting plate 6 is slidably connected to the fixed seat 3. A driving component 19 for driving the displacement and extrusion mechanism 18 to squeeze and clamp the glass is installed on the side of the mounting plate 6 close to the displacement and extrusion mechanism 18.

[0041] The first adjustment component includes a second electric push rod 7 fixed above the fixed shell 2, a lifting shell 8 is fixed to the output end of the second electric push rod 7, a sliding rod 9 is symmetrically fixed to the bottom of the lifting shell 8, the sliding rod 9 is slidably connected to the fixed seat 3, and a motion component is installed in the lifting shell 8 to enable the two electric vacuum suction cups 4 to move toward each other.

[0042] The motion component includes a bidirectional screw 10 rotatably connected to the inner wall of the lifting shell 8, and the outer wall of the bidirectional screw 10 is symmetrically threaded with a slider 11. The slider 11 is slidingly connected to the inner wall of the lifting shell 8. The slider 11 is fixed to the electric vacuum suction cup 4. A first motor 12 is fixed to one side of the lifting shell 8, and the output end of the first motor 12 passes through the lifting shell 8 and is fixed to the bidirectional screw 10.

[0043] This application sets a first adjustment component so that when the special-shaped glass cup conveying component is conveyed to the middle of the positioning structure, the electric vacuum suction cup 4 can be used to adsorb the glass to enhance the stability of the glass positioning, and since the distance between the two electric vacuum suction cups 4 can be adjusted, it can adapt to special-shaped glasses of various sizes.

[0044] Figure 1 A second embodiment is provided, which mainly differs from the first embodiment in that: the second adjustment component includes a scissors-type structure 13 installed above the displacement and extrusion mechanism 18, the displacement and extrusion mechanism 18 located in the middle is fixed to the fixed seat 3, the displacement and extrusion mechanisms 18 located on both sides of the middle displacement and extrusion mechanism 18 are slidingly connected to the fixed seat 3, and a third electric push rod 14 is fixed above the fixed seat 3, and the output end of the third electric push rod 14 is fixed to a displacement and extrusion mechanism 18 at the edge.

[0046] The first motor 12 is a reduction motor.

[0047] This application sets a second adjustment component so that when using the displacement extrusion mechanism 18 to accurately position the special-shaped glass, the spacing between multiple displacement extrusion mechanisms 18 can be adjusted to facilitate covering the side edges of the clamped special-shaped glass, thereby stably positioning the special-shaped glass and improving the scope of application of the device.

[0048] Working principle:

[0050] The special-shaped glass is placed on the conveying assembly, and the two conveying rollers 15 connected to it are driven by the double-headed motor 16 to rotate, so that the conveyor belt 17 performs conveying work on multiple conveying rollers 15, and moves the glass to the middle of the positioning structure; then the first motor 12 drives the bidirectional screw 10 to rotate, so that the slider 11 moves in the lifting shell 8, and the two electric vacuum suction cups 4 move towards each other, so that the distance between the electric vacuum suction cups 4 is adjusted according to the positioning requirements of the glass, and then the second electric push rod 7 is extended, the slide bar 9 slides in the fixed seat 3, the lifting shell 8 rises, and the electric vacuum suction cups 4 adsorb the special-shaped glass.

[0051] Then, the spacing between the multiple displacement and extrusion mechanisms 18 is adjusted according to the side of the special-shaped glass to ensure that the displacement and extrusion mechanisms 18 can cover and clamp the side of the glass; the extension of the third electric push rod 14 reduces the spacing, and vice versa; then the driving components 19 are used in sequence to extend the multiple displacement and extrusion mechanisms 18 to clamp and position the special-shaped glass; the first electric push rod 5 makes the mounting plate 6 close to the displacement and extrusion mechanism 18, and when the driving component 19 cooperates with the displacement and extrusion mechanism 18, the displacement and extrusion mechanism 18 can extend to clamp and position the glass.
