The silver paste carbon paste fully automatic screen printing machine is widely used in the thick film circuit industry, semiconductor industry, medical industry, and heating products industry, mainly for printing conductive silver paste, through-hole silver paste, graphene carbon paste, and insulation oil.
With the continuous application of thick film circuits in various industrial, military, and life fields, in the pursuit of lightweight, conductive, heating, and more precise data transmission processes, silver paste carbon paste is often printed on plates made of ceramic chips, silicon chips, FPC, and other special materials to form different thick film circuits. Due to different usage scenarios and functional requirements, the fully automatic screen printing machine used for printing mainly has the following functional characteristics:
Fully automatic function: When designing printing equipment for silver paste and carbon paste, manufacturers first consider saving time, effort, efficiency, and cost, and cooperate with customer requirements to achieve fully automatic printing machine production and intelligent management. Therefore, the entire production line from loading, printing, unloading, detection, caching, and baking is designed as an automated production process.
High precision function: In order to ensure the uniformity of printing film thickness, the fully automatic screen printing machine used for silver paste carbon paste printing is controlled within the absolute range during resistance testing. Therefore, the production environment, printing paste characteristics, and printing equipment requirements are constantly improved. In terms of equipment, the flatness of the printing brush table, the parallelism between the screen and the platform, the uniformity of printing pressure, air pressure stability, the alignment method of the printing substrate, and precision all need to be tested with a meter, Digitized and intuitive display of important hardware parameters of printing equipment provides important evidence data for precise management of production data, and also provides important parameters for continuous improvement of printing quality.
Intelligent function: Currently, some customers have achieved intelligent management in production, and quality management and traceability have achieved data storage and analysis. Each process in the production process requires scanning and tracking, and complete recording of production parameters, production date, machine number, and operator details for each substrate. When designing a fully automatic screen printing machine for silver paste and carbon paste, Ebola fully considers the intelligence of the equipment. In addition to adding an MES system, scanning and tracing are required Remote monitoring, device permissions, etc. are also fully open ports as required.
Practical functions: In addition to ensuring printing accuracy, the fully automatic screen printing machine used in the production of silver paste and carbon paste should also fully consider the production characteristics of silver paste and carbon paste printing in terms of practicality. In addition to basic functions such as dust removal and static electricity removal, it is also equipped with practical functions such as automatic slurry addition device, vacuum plug hole function, net bottom cleaning function, scanning and tracing function, equipment self inspection and self inspection in the aspect of slurry addition.
Automatic feeding function: The silver paste carbon paste fully automatic screen printing machine has an automatic feeding and discharging function. As long as the substrate is filled with the feeding frame, the feeding device will automatically grab the material and collect the isolation paper. Generally, one feeding can be enough for the equipment to produce for more than 2 hours, and the printing equipment has an automatic recognition of multiple sheets and a shortage alarm function. Therefore, the operator can watch 2-3 machines per person, greatly reducing manual input.

Automatic alignment function: Silver paste carbon paste fully automatic screen printing machines all have automatic alignment function, generally using 2 CCD industrial cameras to grasp diagonal alignment or 4 CCD four corner alignment, depending on the size of the substrate, material expansion and contraction deformation, and customer precision printing requirements. The alignment speed is within 0.3 seconds, the alignment accuracy can reach 0.002mm or more, and it supports multiple communication methods. When achieving continuous printing or mass production, ensure the uniformity of product printing accuracy and quality.
Automatic printing function: After the printing substrate is automatically aligned and OK, the material is transported to the printing platform of the fully automatic screen printing machine to perform the automatic printing function. The design of the printing head and screen structure, the flatness of the printing platform, the parallelism between the screen and the printing platform, the stable output scraper pressure, scraper angle, printing speed, ink return speed and other factors are key factors affecting the printing quality.
Automatic feeding function: The silver paste carbon paste fully automatic screen printing machine is generally designed as an automatic feeding rack or a feeding tunnel furnace on the assembly line according to the requirements of the subsequent baking process. Compared with the baking process connected to the tunnel furnace, feeding is simpler. After the printing machine completes the printing work, the feeding module can directly grab the material and place it on the assembly line. The feeding rack is suitable for the oven baking process, and the entire feeding rack is automatically filled with material and pushed into the oven for baking. It is suitable for processes that require static and long baking time after printing.
Easy operation of fully automatic screen printing machine: Due to the intelligent functions of the silver paste carbon paste fully automatic screen printing machine, the operation is also simple and easy to learn. After the new equipment enters the factory, the manufacturer will send after-sales personnel to follow up on production for a period of time, and one-on-one training will teach operators how to start up and alarm. Different product printing parameters can be saved in local equipment. The next time the same model of product is produced and printed, the parameters can be directly called to reduce machine adjustment time, and the parameters are unified to ensure consistent printing quality.
