Liquid spray chip of printing module of rapid prototyping device and liquid spray control circuit thereof

Abstract

The invention relates to a liquid spray chip which has a length and a width constituting a total area region. The total area region contains a non-wiring area and a wiring area. At least three liquid supply tanks are arranged in the non-wiring area in parallel, and each liquid supply tank is communicated with one liquid storage chamber in the cartridge body of a liquid spray cartridge. A liquid spray control circuit is arranged in the wiring area. The liquid spray control circuit includes multiple liquid droplet generators, and each liquid droplet generator is composed of a heating resistor, a driving transistor, and a liquid spray hole. The liquid spray control circuit receives power signals, print data signals, preheating data signals, preheating control signals, reverse preheating control signals, heating control signals, and reverse heating control signals, and is connected with a common endpoint to control the liquid droplet generators.

Description

technical field [0001] The invention relates to a liquid spraying chip and a liquid spraying control circuit thereof, in particular to a liquid spraying chip and a liquid spraying control circuit of a printing module of a rapid prototyping device. Background technique [0002] Rapid prototyping technology (RP technology for short) is developed based on the concept of building a pyramid-like layer stacking molding. Automatically and quickly convert the design scheme of any complex shape into a 3D solid model, which greatly shortens the development cycle of new products and reduces the cost of research and development, and can ensure the time to market of new products and the first-time success rate of new product development. Molding technology provides a more complete and convenient product design communication tool for technical personnel, as well as between technical personnel and enterprise decision makers, product users and other non-technical personnel, thus significant...

Problems solved by technology

[0006] However, when the rapid prototyping jet printing operation of this 3D object is implemented, in addition to containing black and color inks, the printing ink cartridge 12 needs to contain an additional high-viscosity adhesive to bond the construction materials, and then can be layered. Layers are stacked to form 3D objects. Therefore, traditional rapid prototyping devices need to be equipped with additional carriers and printing ink cartridges to accommodate high-viscosity adhesives. In this way, the overall volume of the printing module 1 will increase. , while increasing the cost of the carrier and print cartridges
