Problems solved by technology
[0003] In the PCB / FPC industry, in the traditional ink scraping process, the ink is mainly used to scrape the ink on one side of the plug hole, and the excess ink on the through-hole surface of the circuit board is scraped off by rolling the roller. Ink, and in the ink scraping process, the front and back sides of the same board need to be scraped once, and the force on one side will easily lead to bending and deformation of the board, and the ink on the non-stressed side will bulge, resulting in bad rework

Embodiment
[0039] Example: such as Figure 1-Figure 6 Shown, a kind of double-sided scraping type ink process, comprises the following steps:
[0040] 1) Start the ink scraper;
[0041] 2) Manually move the material plate to the feeding platform;
[0042] 3) The feeding platform moves the material plate to the conveying wheel;
[0043] 4) The conveying wheel pushes the material plate to the right to move;
[0044] 5) The upper and lower scrapers press the PET film on both sides and clean the ink on both sides of the material board at the same time;
[0045] 6) The material plate after ink cleaning is pushed to the blanking platform;
[0046] 7) The material plates are moved and stacked on the top plate in an orderly manner after detaching from the blanking platform;
[0047]8) After the stack count is full, the finished product is manually removed by the worker.
[0048] The PET film at the upper and lower ends is set as a mirror image. When the top winding roller and the bottom wi...

The invention relates to the technical field of printing ink scraping, and discloses a double-side printing ink scraping technique and a double-side-printing-ink-scraping-type printing ink scraping machine. According to the invention, a PET film is guided by four groups of guiding rods to pass below scrapers and then are wound on the periphery of a top reeling roller; the films at the upper and lower ends are arranged in a symmetry manner; when the top reeling roller and a bottom reeling roller rotate, the PET film pass below the scrapers and scrape the printing ink synchronously for upper andlower sides of as plate; through the PET films which are arranged symmetrically, the upper and lower end surfaces of the plate can be subjected to printing ink scraping while the plate moves, so thatproduction efficiency is greatly improved; through the plate which is subjected to synchronous printing ink scraping on two sides, double-side synchronous printing ink scraping can be realized in onemoving process, so that the phenomenon that the plate needs to be overturned after printing ink on one side is scraped, and printing ink on the surface of the plate which is subjected to printing inkscraping swells is avoided; and the transmission direction of the plate is the same as the transmission direction of the printing ink absorbing film, so that the printing ink can be carried away in time, and accumulation of the printing ink is avoided.
Description
technical field [0001] The invention relates to the technical field of ink scraping machines, in particular to a double-sided ink scraping process and a double-sided oil scraping type ink scraper. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of linking material (resin), pigment, filler, auxiliary agent and solvent, etc. It is used for various printing of books, magazines, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. [0003] In the PCB / FPC industry, in the traditional ink scraping process, the ink is mainly used to scrape the ink on one side of the plug hole, ...
