The following is how to use the board leveling device.

The main embodiment of the present invention uses two sets of the authors in combination to improve the efficiency of ink removal. However, since the two sets of the creation do not need to have two sets of independent transport tracks 10, the main implementation is In the example, the two sets of the authoring system share a set of transport tracks 10.

The method of using the circuit board comprises a preparation step, a pressing step and a scraping step, and the details of each step are sequentially described below.

Preparation steps: Referring to FIG. 1 and FIG. 4, a conveying rail 10, an upper roller 21, a lower roller 22, an upper scraper 31 and a lower scraper 41 are prepared. The upper roller 21 and the lower roller 22 are respectively disposed on the conveying rail 10 Above and below, the upper scraper 31 and the lower scraper 41 are respectively disposed above and below the transport rail 10; all the components in the preparation step are the same as those mentioned in the circuit board leveling device of the present invention, It is not described here, but the components in the preparation step are not limited to the same components as the aforementioned board leveling device.

Referring to FIG. 6 further, in the preparation step, the user can move the distance of the upper roller 21 relative to the transport rail 10 up and down according to the thickness of the circuit board 91 to be processed, thereby adjusting the circuit board 91 to receive the upper roller 21 And the spacing between the lower rollers 22.

More precisely, the preparation step may further include an upper receiving tray 32 and a lower receiving tray 42. The upper receiving tray 32 is provided with an adhesive layer 33, and the lower receiving tray 42 is provided with an adhesive layer 43. The receiving trays 32, 42 and the adhesive layers 33, 43 of the steps are respectively the same as those mentioned in the aforementioned circuit board leveling device, and therefore will not be described herein.

Pressing step: Referring to FIG. 1, FIG. 4 and FIG. 5, a circuit board 91 is placed on the transport rail 10, and the circuit board 91 is driven by the transport rail 10 to face the upper roller 21 and the lower roller in the transport direction L. When the circuit board 91 moves between the upper roller 21 and the lower roller 22, since the upper roller 21 and the lower roller 22 respectively rotate in opposite directions, the circuit board 91 can be further pressed simultaneously and along the conveying direction. L pushes forward the power.

When the upper roller 21 and the lower roller 22 press the circuit board 91, the excess ink 94 on the circuit board 91 can be adhered to the upper roller 21 and the lower roller 22, more precisely, due to the upper roller 21 and the lower roller 22 The material is a slightly elastic rubber, so that when the circuit board 91 is slightly pressed, the ink 94 can be adhered to the upper roller 21 and the lower roller 22 due to the pressure.

The scraping step: Referring to FIG. 5 and FIG. 6, the upper roller 21 and the lower roller 22 adhered to the ink 94 continuously rotate, and respectively abut against the upper scraper 31 and the lower scraper 41, and the upper scraper 31 and the lower scraper When the two rollers 21 and 22 are continuously pressed against each other, the area of the upper roller 21 and the lower roller 22 to which the ink 94 is adhered gradually approaches the upper blade 31 and the lower blade 41, and is further subjected to the upper blade 31 and the lower portion. The scraping of the scraper 41 causes the ink 94 to be scraped off by the upper scraper 31 and the lower scraper 41.

More precisely, since the upper receiving tray 32 and the lower receiving tray 42 are respectively provided with adhesive layers 33, 43 in the preparation step, when the scraped ink 94 falls to the corresponding upper receiving tray 32 or lower After the tray 42 is received, it will be adhered by the two adhesive layers 33, 43 so that the ink 94 will not be randomly splashed.

When too much ink 94 is adhered to the adhesive layers 33, 43, the user can maintain the viscosity by replacing the adhesive layers 33, 43.

The following are the advantages of this creation.

In the use of the present invention, since the disposable material is not required in the step of adhering the ink 94, the upper roller 21 and the lower roller 22 can be directly adhered, and subsequently passed through the upper blade 31 and the lower blade 41. The ink is scraped off from the upper roller 21 and the lower roller 31 by operation; in other words, the upper roller 21 and the lower roller 22 after the ink 94 is scraped off can continue to function as a tool for adhering the ink 94 under continuous rotation. The creation can eliminate the need for disposable ink sticking equipment, and the use of the roller itself can achieve the purpose of repeated adhesive ink, thus effectively reducing the cost of the use of the creation.

Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present invention, and is not in any technical field. Generally, those skilled in the art can make some modifications or modifications to the equivalent embodiments by using the technical contents disclosed above, but without departing from the technical solutions of the present invention.
