DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1-4As shown in the figure, the utility model provides a technical solution: a curved screen printing squeegee device for a touch screen glass cover plate, which includes a base 1. A vertical plate 2 is fixedly connected to the top of the base 1. A horizontally arranged moving plate 3 is provided on the front side of the vertical plate 2. A first electric sliding table 4 and a second electric sliding table 5 are respectively fixedly connected to the front side of the vertical plate 2 and the front side of the moving plate 3. The moving plate 3 is slidably connected to the first electric sliding table 4. A movable block 6 is slidably connected to the second electric sliding table 5. A squeegee 7 is fixedly connected to the bottom of the movable block 6. A screen 8 is arranged below the squeegee 7. Clamping plates 9 are arranged on both the left and right sides of the screen 8. The clamping plates 9 are slidably connected to the bottom of the movable plate. A placing plate 10 is arranged below the screen 8. Two grooves are opened on the placing plate 10. Flipping plates 20 are slidably connected in both of the two grooves. The opposite sides of the flipping plates 20 are both arc surfaces. A slot is opened on the base 1. A motor 12 and an air pump 15 are both fixedly connected in the slot. The motor 12 is located directly below the placing plate 10. A support plate 13 is fixedly connected to the bottom of the placing plate 10. The support plate 13 is movably connected to the slot and is fixedly connected to the output shaft of the motor 12. A vacuum chuck 18 is arranged on the placing plate 10. An air pump 15 is fixedly connected to the slot. A hose is connected between the air pump 15 and the vacuum chuck 18.

[0023] According to the overall structure of the device, during use, place the glass cover plate on the vacuum chuck 18, and extract air through the air pump 15 to make the vacuum chuck 18 adsorb and fix the glass cover plate. If it is a curved glass cover plate, the bolt 21 can be rotated to loosen the flipping plate 20, then the flipping plate 20 is erected, and then the bolt 21 is rotated in the reverse direction to tighten, so as to fix the curved glass cover plate. After that, clamp the screen 8 between the clamping plates 9, pour the dye above the screen 8, start the first electric sliding table 4 to drive the moving plate 3 to drive the screen 8 to move downward, so that the screen 8 contacts the glass cover plate. When it is a flat glass cover plate, start the second electric sliding table 5 to drive the movable block 6 to drive the squeegee 7 to move to level the dye printed on the glass cover plate. When it is a curved glass cover plate, start the motor 12. The motor 12 drives the placing plate 10 to deflect through the support plate 13, thereby driving the glass cover plate to deflect. At the same time, the clamping plate 9 drives the screen 8 to move in the same direction, so as to perform curved screen printing.

[0024] As Figure 2 shown, the motor 12 is located directly below the placing plate 10. The distance from the arc surface to the plane of the flipping plate 20 plus the distance from the bottom surface of the flipping plate 20 to the bottom surface of the groove plus the distance from the bottom surface of the placing plate 10 to the axis of the output shaft of the motor 12 is equal to the radius of the arc surface of the placing plate 10.

[0025] Through the above structure, when the flipping plate 20 is erected, the center of the arc surface at the top of the flipping plate 20 is located at the axis of the output shaft of the motor 12. Thus, when the motor 12 drives the flipping plate 20 to deflect, the curved glass cover plate and the screen 8 remain in contact, preventing the two from separating and causing screen printing failure.

[0026] AsFigure 3 As shown, a plurality of uniformly distributed threaded holes are provided in the top of the placement plate 10 and the arc surface of the flipping plate 20. A first screw rod 16 is threadedly connected in the threaded holes. A fixing block 17 is fixedly connected to the end of the first screw rod 16, and a vacuum chuck 18 is fixedly connected to the fixing block 17.

[0027] The first screw rod 16 can be rotated through the fixing block 17 to take out or screw the first screw rod 16 into the threaded hole, so as to quickly and conveniently adjust the position of the vacuum chuck 18, so as to be applicable to fixing glass covers of different sizes.

[0028] As Figure 2 shown, two support rods 11 are provided in the slot. The two support rods 11 are located at the left and right ends of the bottom of the placement plate 10. Sliding grooves are provided at the top of the front and rear sides of the slot. The front and rear ends of the support rods 11 are inserted into the adjacent sliding grooves and fixed by screws.

[0029] The two support rods 11 provide support for the placement plate 10 during the screen printing of flat glass covers to prevent the placement plate 10 from deflecting to both sides. The fixing and movement of the support plate 13 are facilitated by the screws and the sliding grooves.

[0030] As Figure 2 shown, arc-shaped slide rails 14 are fixedly connected to both the front and rear sides of the slot. Sliders are fixedly connected to the bottom of the placement plate 10 near the four corners, and the four sliders are respectively slidably connected to the adjacent arc-shaped slide rails 14.

[0031] The slide rails provide support for the deflection process of the placement plate 10 during the screen printing of curved glass covers, and enable the placement plate 10 to deflect smoothly.

[0032] As Figure 4 shown, slots are provided on the opposite sides of the two clamping plates 9. The left and right sides of the screen 8 are inserted into the adjacent slots. A third electric slide table 22 is fixedly connected to the bottom of the movable plate. The two clamping plates 9 are both slidably connected to the third electric slide table 22. Threaded holes are provided at the top of the clamping plates 9, and a second screw rod 19 is threadedly connected in the threaded holes. The bottom end of the second screw rod 19 abuts against the top of the screen 8, and a knob is fixedly connected to the top end of the second screw rod 19.

[0033] The disassembly and assembly of the screen 8 are facilitated by the slots. The two clamping plates 9 drive the screen 8 to move through the third electric slide table 22. The second screw rod 19 is rotated through the knob to make the second screw rod 19 abut against the screen 8, so as to fix the screen 8 and prevent the screen 8 from sliding in the slot, resulting in screen printing errors.

[0034] Working principle: When in use, place the glass cover plate on the vacuum suction cup 18, and extract air through the air pump 15 to make the vacuum suction cup 18 adsorb and fix the glass cover plate. If it is a curved glass cover plate, the bolt 21 can be rotated to loosen the turning plate 20, then the turning plate 20 is erected, and the bolt 21 is rotated in the reverse direction to fasten it, so as to fix the curved glass cover plate. After that, insert the silk screen 8 into the slot, rotate the first screw rod 16 to fasten it, pour the dye above the silk screen 8, start the first electric slide table 4, so that the moving plate 3 drives the silk screen 8 to move downward, making the silk screen 8 contact the glass cover plate. When it is a flat glass cover plate, start the second electric slide table 5, so that the movable block 6 drives the squeegee 7 to move to level the dye printed on the glass cover plate. When it is a curved glass cover plate, start the motor 12, and the motor 12 drives the placement plate 10 to deflect through the support plate 13, thereby driving the glass cover plate to deflect. At the same time, the third electric slide table 22 makes the clamping plate 9 drive the silk screen 8 to move in the same direction, so as to perform curved screen printing.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
