Abstract
Disclosed is a light transmission detection method of a panel of an electrical product, which makes a light transmission detection worktable that can sends out light beams from the bottom according to the outline size of the panel of the specific electrical product; a piece of panel detection paper adopts a piece of transparent film paper which is printed in proportion as 1:1 and made into a piece of transparent detection paper in proportion as 1:1; the panel to be detected is positioned on a light transmission detection tool equipment, then the transparent detection paper in proportion as 1:1 is placed on the panel, a benchmark is defined correctly, and the size and character detection of the panel can be conducted according to the size, range and brightness of light transmission. The detection method has advantages of high examination efficiency, low error rate and reduced configuration of detecting tools.
Description
Technical field
A kind of electric products panel light transmission checking method of the present invention, this method go for the panel detection work of all kinds of electric products.
Technical background:
Exist a large amount of panel base parts in electric product, the panel base part is mainly used in devices such as pushbutton switch, pilot lamp, instrument and meter are installed.The panel base part all is an operation interface generally, in operation interface pushbutton switch, pilot lamp, instrument and meter below various character prompting is arranged.Such panel mainly is to adopt numerical control to dash processing, carries out surface treatment after the completion of processing again, the character different according to different demand silk-screens after surface treatment finishes.This base part mainly contains two big characteristics: the one, and processing dimension is more, needs to process the circular hole and the square hole of a plurality of different sizes usually in panel.The 2nd, more character prompting is arranged around difform circular hole and square hole.Original panel detection method is the first step: each processing dimension according to the drawing counter plate is measured, and has what processing dimensions just must measure how many times.Second step is according to check and correction size of the character in the drawing counter plate and content.The deficiency of the existence of this kind operational method is: each processing dimension, each character size all must be measured, and the efficient that detects panel is too low; A lot of tiny characters are not easy to detect and proofread, and error rate is higher; Need the different checking tool of configuration, simultaneously in checking process also otherwise with change; In testing process,, be easy to generate omission because human factor is more.
Summary of the invention
The purpose of this invention is to provide a kind of electric products panel light transmission checking method that adopts the printing opacity technology to carry out panel detection.This method has changed existing characterization processes method.Make the detection of panel oversimplify, improved the error rate that detects the efficient of panel and reduced panel detection.
A kind of electric products panel light transmission checking method, it may further comprise the steps and is:
The first step, make printing opacity and detect frock: the physical dimension according to concrete electric products panel is made the printing opacity testing platform that can go out light from bottom emission;
In second step, make the transparent detection drawing of 1:1: adopt clear films paper to carry out the printing of 1:1 in the panel detection drawing, obtain the transparent detection drawing of 1:1 panel;
The 3rd step, panel detection: the panel that will need to detect is placed on the printing opacity detection frock of making according to described first step method, to be placed on above the panel according to the transparent detection drawing of 1:1 that described second one step process is made then, find benchmark accurately, the size detection and the character that carry out panel according to size, scope, the brightness of printing opacity detect.
Its size detection and character detection for having finished electric products panel by the printing opacity technology, the configuration that checking efficiency height, error rate be low, reduced testing tool.
Embodiment
So that road maintainance machinery electric products panel B11 is detected is example, 25 of its total perforates, and panel character has 40.The first step is made the printing opacity testing platform that can go out light from bottom emission according to the physical dimension of concrete panel B11, and the making of printing opacity testing platform adopts electricity-saving lamp to make, and adopts the enclosed lamp box method work top that is made.This worktable adopts switch control.In the process of design, consider the convenience of light degree and operation.In second step, adopt transparent membrane to carry out the printing of 1:1 in the original detection drawing of maintain road mechanical electric products panel B11.The 3rd step, the road maintainance machinery electric products panel B11 that needs are detected is placed on the printing opacity testing platform, opening power is found transparent detection drawing accurately benchmark then and is placed on above the road maintainance machinery electric products panel B11 panel that size, scope, brightness according to printing opacity begins to carry out size detection and character detects.
This characteristic feature of an invention detects for size detection and the character of having finished electric products panel by existing ripe printing opacity technology, main effect has: 1, checking efficiency height: identical product can improve 3 times on detection efficiency, for example: road maintainance machinery electric products panel B5 need spend ability detection in 20 minutes according to original inspection method and finish, and only needs 6 minutes just can finish all testings after the employing printing opacity check-up method.2, error rate is low: original detection method needs the check of processing dimension one by one, and error rate is higher, adopts the transparent membrane drawing comparison and detection of 1:1 now, can not go wrong because of size detection.3, reduce the configuration of testing tool: original inspection process need dispose a large amount of checking tools, as vernier caliper, tape measure etc.Only need the visual inspection of contrast 1:1 transparent membrane drawing to get final product now.
Claims (1)
1. electric products panel light transmission checking method is characterized in that it may further comprise the steps:
The first step, make printing opacity testing platform: the physical dimension according to concrete electric products panel is made the printing opacity testing platform that can go out light from bottom emission;
In second step, make 1: 1 transparent detection drawing: adopt clear films paper to carry out 1: 1 printing in the panel detection drawing, obtain 1: 1 transparent detection drawing of panel;
The 3rd step, panel detection: the panel that will need to detect is placed on the printing opacity testing platform of making according to described first step method, to be placed on above the panel according to 1: 1 transparent detection drawing that described second one step process is made then, find benchmark accurately, the size detection and the character that carry out panel according to size, scope, the brightness of printing opacity detect.
