Inkjet device for led support and inkjet method thereof

Abstract

The invention discloses a set of LED support inkjet equipment and an inkjet method of the LED support inkjet equipment. The inkjet equipment comprises an upper mold, a lower mold, an ink box, an ejector pin, an ink suction air cylinder, an inkjet air cylinder, an ink scraping air cylinder, a horizontal workbench, a vertical supporting frame and a controller. Driving actions of all the air cylinders on the ink box, the ejector pin and the upper mold can be intelligently controlled by the controller so that ink storage space can be automatically reserved and automatic ink filling and automatic inkjet and the like can be achieved, the inkjet efficiency is improved, and the production cost is reduced. High-seal high-pressure inkjet operation can be performed on LED supports in a mode of an immersion cavity, so that the inkjet layer of each LED support is compact and uniform, the adhesion force is increased, ink overflow, leaky white, irregularity and other undesirable phenomena cannot happen easily, and the quality of the products is improved. Meanwhile, a plastic base of each LED support does not need to be formed for the second time, the production cost is reduced, and the performance of the products is improved. In the inkjet mode, the distance between the LED supports can be smaller (larger than 0.3 mm), and complex LED supports with high density, large area and multiple particles can all be produced efficiently.

Description

technical field [0001] The invention relates to the technology in the field of LED inkjet, in particular to an inkjet device for an LED bracket and an inkjet method thereof. Background technique [0002] With the rapid development of LED chip technology and the maturity of application technology, LED lamps are getting closer and closer to our daily life. As a new type of energy-saving and environmentally friendly light source, LED outdoor display screens are closely watched by people. Many countries and Enterprises invest a lot of manpower and financial resources in R&D and production. [0003] Usually, in order to make the overall display effect of the display screen more clear and the picture more beautiful, people often print black ink on the outer side of the plastic body so that the LED bracket can effectively avoid the influence of the white plastic on the plastic body on the contrast of the display screen, thereby , improve the display clarity of the LED display, and...

Problems solved by technology

However, the plastic base requires two sets of molds to be completed through secondary molding. The mold cost is high, the production efficiency is low, and the scrap rate is high, resulting in a significant increase in production costs.
