Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to an automatic squeegee printing device. Background Art

[0002] Screen printing consists of five major elements, namely a screen printing plate, a squeegee, ink, a printing table, and a substrate. The basic principle of screen printing is as follows: Utilize the basic principle that the mesh holes in the graphic part of the screen printing plate are permeable to ink, while the mesh holes in the non-graphic part are impermeable to ink for printing. During printing, ink is poured onto one end of the screen printing plate, and a certain pressure is applied to the ink part on the screen printing plate with a squeegee, while moving towards the other end of the screen printing plate at the same time. The ink is squeezed from the mesh holes in the graphic part to the substrate during the movement. The efficiency and accuracy are relatively low during the use of the printing device. Therefore, there is an urgent need for an automatic squeegee printing device.

[0003] After retrieval, an automatic squeegee printing device disclosed in Chinese Patent CN219191601U includes an operating table. A carrier table is fixedly connected to the top of the operating table. A positioning groove is formed in the top of the carrier table. Two positioning plates are symmetrically and slidably connected in the positioning groove. One side of the carrier table penetrates and is rotatably connected to a double-headed screw, and the two positioning plates are respectively sleeved at both ends of the double-headed screw; Two mounting plates are symmetrically and fixedly connected to the top of the operating table. A connecting block is rotatably arranged between the two mounting plates. A printing screen plate is fixedly connected to one side of the connecting block, and the connecting block is driven by a motor. By providing the positioning groove and the positioning plates, when the circuit board is placed in the positioning groove, the preliminary positioning of the circuit board is realized. Then, through the mutual approach of the two positioning plates, the circuit board is automatically centered, and the secondary positioning of the circuit board is realized. The positioning effect on the circuit board is good, avoiding misalignment in the printing position, thereby improving the printing effect on the circuit board.

[0004] The above-mentioned automatic squeegee printing device has the following technical defects:

[0005] During the process of printing an object, first, the motor drives the strip plate and the squeegee to rotate, and then the motor drives the connecting block and the printing screen plate to rotate. Only then can the object to be printed be placed at the bottom of the printing screen plate for printing. The operation process during use is relatively troublesome, which is not conducive to improving the printing efficiency. At the same time, the motor drives the bidirectional screw to rotate, and the bidirectional screw drives the two positioning plates to move in opposite directions, thereby clamping the circuit board. After the circuit board is printed, it is located inside the positioning groove. Usually, the two ends of the circuit board are pinched by hand to take it out. When the hand strength is too large, it is easy to bend and deform. Summary of the Utility Model
