According to this film panel sample, a careful observation, the product is gray and black, the font is white and green, there are 7 LED indicator holes (window opening), there are 2 round raised keys. The material feels good, using fine sand material to avoid damage to the surface.
Take out a ruler, measure, the product length 260mm, width 180mm, 4 corners of the radius of 5mm, respectively measure the diameter and position of 7 display Windows and relative position, and measure the diameter of the convex hull button, and then measure the size and relative position of each font on the panel. Now that you have the dimensions and relative position, you can start drawing.
Open the Coreldraw software and create a new file with the resolution set to 300 pixels in enhanced mode. First place a rectangle with a rounded radius of 5mm and a length and width of 260mm and 180mm respectively, the background is set to black 90% black, then place the various fonts, including Chinese characters and English, and the dividing line, then place the transparent hole, and then place the convex keys and the words and lines on the convex keys. The respective sizes and relative positions were carefully examined. The design drawing of the film panel has been preliminarily completed, as shown below:
After the design drawing of the film panel of the ultrasonic screen cleaning device was sent to the customer to confirm that it was correct, it began to implement, and then it was necessary to design and produce the film file and the knife die file of the film panel.
Film file, the product, there are white, green, black and gray black, need to pay special attention to is: green in the black background, the color will change greatly, in order to overcome this shortcoming, the green background needs white substrate; At the same time, the gray and black background is not enough to hide the ugliness, once in the process of screen printing panel, hand grain or dust stuck to the panel, will make the panel directly scrapped, so the background color gray and black should be as early as possible on the material.
Based on the above two points, the first screen print should be white, including the white edge of the raised keys. The second color should be the background color gray black, green font, transparent display window, and circular keys, should be hollowed out. The third color should be black, only at the round button. The fourth color that should be silk-screened is green including the words on the panel and the circular keys themselves. Fifth need to screen a layer of board color on the back of the green font. In this process, the gray and black should press the white edge of the key a little, the green should press the white circular edge some, and the green should also press the gray and black hollow out some. The final white background color and green can be used on the same screen. When designing film files, we pay special attention to the following points:
1, film files must not appear in RGB format, must also be CMYK format.
2, there must be boundary lines, cutting lines, alignment lines, positioning lines, and appropriate boundary lines, cutting lines, alignment lines and positioning lines are the premise of efficient and correct follow-up work.
3, be sure to determine the order of each color, the edge must be pressed.
4, it is best to mark the edition color of each page on the film document, to facilitate the confirmation of the staff on duty and the screen printing staff, to avoid mistakes and improve efficiency.
After the production of film documents, the next to do knife mold and hardware mold files.
Two die files are required, the first is the contour die, which needs to have positioning posts, and the second is the double-sided tape die, which is used to cut the double-sided tape to fit the raised keys and the transparent LED indicator hole. Taking into account the extra deviation of the punching shape, the author appropriately reduced the outline size of the product in the outline die file, reducing the length of 260mm and the width of 180mm to 259.8mm and 179.8mm respectively. Positioning column Remarks Spring positioning column, with a small diameter of 3mm, using an imported knife. In the knife die of the double-sided tape, the shape of the double-sided tape should be larger, in order to facilitate and assemble, the author set the length and width to 264mm and 184mm respectively, and the position of the LED indicator hole and the key, leaving a margin of 2.5mm. That is, the diameter of the original transparent window is 8mm, so in the die file, the circular hole is 10.5mm.
Hardware mold. You need it when you raise the keys. The size of the hardware mold should not be smaller than the appearance of the product panel to avoid leaving indentations on the panel when the keys are raised. The diameter of the circular hole and the diameter of the green key can be equal. In addition to the circular hole required for the raised key, the hardware mold should also have a positioning hole. The author set the positioning hole to 2 circles, whose diameter is 8mm.
Ultrasonic screen cleaning device film panel design drawing, film design drawing, knife mold design drawing, hardware mold design drawing, after the completion of several drawings, we undertake most of the film panel design work has been decomposed and completed.
Shenzhen PCSPCB Technology Co., Ltd. is located in Longgang District, Shenzhen City, is a company specializing in the design and production of film switch panel, the company's production process is sophisticated and stable, fast proofing speed, is trying to build the film switch panel the first brand. In 2019, the company independently developed an online purchase system, ERP management system, which can realize online quotation, self-service ordering, online payment, online production schedule query and other functions to meet the diversified needs of different users.
