[0033] See also Figures 1 to 3 , a printing off-grid dual servo crank 242 connecting rod 243 mechanism, comprising: a frame 1; a frame 2, a first end of which is hinged on the frame 1; a screen plate installed on the frame 2; a lifting mechanism 24, the second end of the frame 2 is connected to the frame 1 through the lifting mechanism 24; a linear module 22, installed on the frame 2; an ink printing assembly 23, connected to the slider of the linear module 22. During the walking and printing process, if the plate is not lifted, the structure at the rear end will bring the ink to the glass. In the process of lifting the plate, there will not be too much ink printed on the glass. When printing ink on the glass, the screen plate is lifted synchronously to avoid defective products caused by the screen plate carrying ink. The servo motor drives the electric cylinder 241 to move through the synchronous belt structure, and the crank 242 connecting rod 243 structure is pushed and pulled to operate.

The crank 242 is driven to swing by the driving mechanism, and the crank 242 drives the connecting rod 243 to move. The height of the lower end of the connecting rod 243 is fixed, thereby pushing the upper end of the connecting rod 243 to move, thereby realizing the lifting and lowering of the frame 2.

[0035] The driving mechanism is an electric cylinder 241, and the piston rod of the electric cylinder 241 is hinged to the second end of the crank 242. The piston rod of the electric cylinder 241 pushes the crank 242 to swing. The electric cylinder 241 is driven by a lifting servo motor 244. The power mechanism is a servo motor, and the full servo synchronous action improves the uniformity of the printed ink layer and the convenience of operation. The servo motor drives the electric cylinder 241 to move through the synchronous belt structure, pushing and pulling the crank 242 and the connecting rod 243 structure to operate.

[0036] The ink printing assembly 23 includes a crossbeam 231 , which is mounted on a slider of the linear module 22 ; a lifting cylinder 232 is disposed on the crossbeam 231 , and a printing plate 233 is disposed on the piston rod of the lifting cylinder 232 .

[0037] Hinge shafts 21 are provided on both sides of the first end of the frame 2 to support the frame 2 to swing.

[0038] A set of lifting mechanisms 24 is respectively provided on both sides of the frame 2, so that the lifting is more stable and reliable.

[0039] The linear module 22 is driven by a printing travel motor. The power mechanism is a servo motor, and the full servo synchronous action improves the uniformity of the printing ink layer and the convenience of operation.

[0040] The above-mentioned method of using the printing off-screen dual servo crank-connecting rod mechanism is to lift the screen upward during printing, and the lifting mechanisms on both sides are independent structures and move simultaneously, and the lifting mechanism movement matches the printing walking rhythm; after printing is completed, the screen is lowered, and the printing walking structure moves in the opposite direction to return ink.

[0041] After adopting the above structure, the screen is lifted synchronously when printing ink on the glass to avoid defective products caused by ink on the screen. The servo motor drives the electric cylinder to move through the synchronous belt structure, and the push-pull crank connecting rod structure operates.
