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 ink scraping, and discloses a double-sided ink scraping process and a double-sided oil scraping ink scraping machine. In the present invention, the PET film passes under the scraper through the guidance of four sets of guide rods and then is wound on the outer edge of the top winding roller. The PET films at the upper and lower ends are mirror images, and the top winding roller and the bottom winding roller When rotating, the PET film passes through the bottom of the scraper to scrape the ink on the upper and lower sides of the board synchronously. By setting the mirrored PET film, the upper and lower sides of the board can be scraped synchronously when moving, which greatly improves the production efficiency. The board with simultaneous scraping of ink on one side can realize double-sided simultaneous scraping of ink during one movement, thus avoiding the need to turn over the board after scraping ink on one side, resulting in raised ink on the surface of the scraped board Under normal circumstances, the transmission direction of the plate is consistent with the transmission direction of the oil-absorbing film to ensure that the ink can be taken away in time to avoid ink accumulation.
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, ...
