This invention discloses a method for printing two-dimensional structures of thermosetting materials with controllable surface roughness, comprising: controlling the rheological properties of the extrusion behavior of a selected thermosetting material; calculating and determining the relationship between the deposition morphology of the thermosetting material and printing parameters, and plotting an H-V phase diagram to determine the critical printing range for achieving uniform deposition; establishing a single-fiber deposition morphology evolution model and a multi-fiber fusion geometric evolution model to provide a correlation between the degree of fusion of adjacent deposited fibers and the surface micro-roughness, thereby obtaining a preset surface microstructure morphology; and, according to the required surface roughness, solidifying and locking the interface through thermal curing at different fusion stages to obtain a continuously adjustable and structurally stable two-dimensional film of thermosetting material. This invention can realize the printing of two-dimensional structures of any thermosetting material system on any spread substrate, and can continuously and programmably adjust the surface roughness.

This utility model discloses a fully automatic screen printing machine based on vision positioning. Its structure consists of a printhead assembly, a vision module, a transmission system, a positioning platform, and a frame. The vision module uses an industrial camera combined with a bar light source to acquire high-precision images of the substrate. Its linkage design with the printhead enables automatic alignment. The transmission system is equipped with an X / Y axis linear module driven by a servo motor and a synchronous belt drive, along with a slider guide rail structure. The array of suction holes on the surface of the positioning platform uses a negative pressure system to fix the substrate, and a cross-shaped reinforcing rib at the bottom enhances rigidity. The screen holder in the printhead assembly uses a spring-loaded plate and an adjustable squeegee holder design to adapt to diverse printing needs. The frame is equipped with adjustable feet and linear guide rails, balancing equipment installation leveling and overall structural stability. With its high precision, high stability, and modular design, this equipment is widely applicable to high-precision printing fields such as electronic components, ceramic decals, and precision circuit boards.

The invention belongs to the technical field of ink-jet printing and discloses an industrial digital ink-jet printing robot which comprises a base plate, a mechanical arm is fixedly connected to the top face of the base plate, a secondary ink box is arranged on the end face of the mechanical arm, an ink-jet mechanism is arranged below the secondary ink box, and a protection mechanism is arranged on the outer side of the ink-jet mechanism. The ink jet mechanism comprises a fixing ring, the fixing ring is fixedly connected to the surface of the mechanical arm, an ink jet pipe is fixedly connected to the interior of the fixing ring, a first baffle is fixedly connected to the inner wall of the ink jet pipe, and a bottom plate is fixedly connected to the inner wall of the first baffle. Intermittent ink output of the device is achieved, intermittent ink jetting can enable an ink path to keep slight circulation, the ink concentration is uniform, the problems of different depths, chromatic aberration and the like in printing are avoided, the stability of long-time printing is guaranteed, and the printing quality and the equipment reliability are improved.

This utility model relates to the field of additive manufacturing printing technology and discloses a printing device for additive manufacturing, including a connecting frame. A rotating seat is fixedly connected to the inner sides of the front and rear of the connecting frame. A rotating shaft is rotatably connected to the inner side of the rotating seat. A swing amplitude adjustment mechanism is provided on the inner side of the top of the connecting frame. A printing mechanism is provided at the bottom of the swing amplitude adjustment mechanism. By manually rotating the locking button according to the swing amplitude of the printed part, the position of the sliding frame and the inside of the rotating sleeve can be adjusted. Then, the locking button is released, and the locking block is re-inserted into the corresponding slot of the rotating frame under the elastic force of the spring. This allows the device to adjust the corresponding swing amplitude according to the swing stroke required by the printed part, thereby avoiding the need for frequent control of the motor's forward and reverse rotation, further increasing the motor's service life and facilitating long-term use of the motor.

This utility model discloses a green printing machine for curved surface screen printing workpieces and its printing head, relating to the field of printing equipment. It includes a printing machine body and a screen. The screen is installed inside the printing machine body. A slide rod is movably installed on one side of the printing machine body, and a connecting block is movably installed on one side of the slide rod. A connecting rod is installed at one end of the connecting block. This utility model solves the problem of mismatch between different brush heads and connecting rod sizes. When small-sized printing is required, simply move the long plate up and use a limiting block to limit the long plate above the slide groove; the mounting plate can then be used as a small-sized brush head. When large-sized printing is required, rotate the rotating block to retract the limiting block into the moving groove, allowing the long plate to slide to the bottom; the long plate can then be used as a large-sized printing brush head. When irregular brush heads are needed, they can be installed on the long plate or the mounting plate according to their size. All brush heads are more stable during the printing process, improving the printing success rate.
