Abstract
The invention relates to a verifying device with adjustable scanning scope. The verifying device mainly comprises a conveying belt unit, a rack body crossing the conveying belt unit, a bare engine unit (mainly including a light source and a CCD) arranged on the rack body, and a controller for controlling a sensor. In order to simultaneously verify a plurality of circuit boards, the controller divides a maximum scope which can be reached by the scanning of the bare engine unit into a plurality of scanning regions with relative number according to the number (input by a user) of the circuit boards to be detected. As spaces kept between strip belts are fixed, each scanning region can be corresponding to the strip belts with predetermined number so that the user can correctly position the circuit boards in the corresponding scanning regions on a basis of the strip belts.
Description
Technical field
The invention relates to a kind of verifying device, refer to the verifying device of adjustable scanning area especially.
Background technology
In order to ensure the demand that meets of the circuit board that has completed (for example boring back), can utilize hole location and aperture on the checking machine testing circuit plate usually.In general, checking machine mainly by the conveying belt group, be crossed on support body on the conveying belt group, be installed in ray machine group (mainly being light source and linear CCD) on the support body and the controller of control sensor is formed.In the conveying belt group, can drive roller bearing by CD-ROM drive motor usually, and then drive many belts, the feasible circuit board under test that is placed on the many belts can take under the support body, and then the ray machine group that is set under the support body scans.
Usually the mode of checking circuit plate obtains earlier the hole image of on-gauge plate and board under test mostly respectively, then mutually relatively after, whether meet demand with the hole location and the aperture of definite board under test.Specifically, after on-gauge plate and board under test were successively brought to the position at ray machine group place, the light source in the ray machine group can utilize the light that penetrates that is throwed, and clearly illuminates hole, and detected by CCD, convert the image and the vector data of this hole then to by computing machine.After obtaining the scan-image of on-gauge plate, then continue more board under test brought and scan, and, determine whether the hole location of board under test and aperture meet demand based on the image data of on-gauge plate.
In traditional mode of operation,, all must scan one by one, and can't scan several pieces simultaneously no matter be the large stretch of circuit board of check or the circuit board of small pieces.Therefore, in such cases,, can only spend more money, purchase the checking machine of greater number if need check board under test in large quantities the time.
Yet, in fact,, take and detect the dice-circuitry plate, but be the detectability of having wasted checking machine really if can detect large stretch of circuit board checking machine of (normally being formed) by a plurality of dice-circuitry plates.If only buy the checking machine that can detect the dice-circuitry plate, but can't check large stretch of circuit board, this does not meet actual demand yet.
Summary of the invention
The present invention's fundamental purpose is to provide a kind of verifying device of adjustable scanning area, and it is divided into a plurality of sweep intervals of relative populations by the maximum magnitude that the ray machine group can be scanned, and checks the polylith circuit board simultaneously.
Based on above-mentioned purpose, the verifying device of adjustable scanning area of the present invention mainly comprises the conveying belt group, is crossed on the support body on the conveying belt group, the controller that is installed in the ray machine group (normally CCD) on the support body and controls sensor.Check the polylith circuit board simultaneously in order to reach, controller can be according to the amount detection of circuit board (normally by user's input), and the maximum magnitude that the ray machine group can scan is divided into a plurality of sweep intervals of relative populations.Because those belts fixing at interval each other, so each sweep interval can correspond to those belts of predetermined quantity, and this makes the user correctly a plurality of circuit boards to be placed within the relative sweep interval based on those belts.
Advantage about the present invention can be by following detailed Description Of The Invention and appended graphic being further understood with spirit.

Embodiment
See also Fig. 1, Fig. 1 is the synoptic diagram of the verifying device of adjustable scanning area of the present invention.As shown in Figure 1, the verifying device 10 of adjustable scanning area of the present invention mainly comprises conveying belt group 25, is crossed on the support body 30 on the conveying belt group 25, the controller (not describing) that is installed in the ray machine group 40 (mainly being light source and CCD) on the support body 30 and controls ccd sensor.This wherein, conveying belt group 25 mainly is made up of the many belts and the roller bearing that can drive those belts.Have preset distance between support body 30 and the conveying belt group 25, and preset distance is at least greater than the thickness of circuit board to be measured.Linear image sensor in the ray machine group 40 (for example CCD) is all towards conveying belt group 25.
See also Fig. 2, Fig. 2 is the operation chart of the verifying device of adjustable scanning area of the present invention.As shown in Figure 2, in the mode of operation of the verifying device 10 of adjustable scanning area of the present invention, scan at circuit board earlier as on-gauge plate, and after the setting parameters, circuit board 16a～16c that the user detects according to for example institute's desire, and the input amount detection is 3 o'clock, but controller on average copies in the enactment document according to the maximum detection width, and according to the amount detection of circuit board 16a～16c, and 40 maximum magnitudes that can scan of ray machine group are divided into a plurality of sweep interval 12a～12c of relative populations, to reach the purpose of checking the polylith circuit board simultaneously.
When reality is placed circuit board 16a～16c, because the fixing at interval each other of those belts in the conveying belt group 25, therefore each sweep interval 12a～12c all can correspond to those belts of predetermined quantity, this makes the user correctly circuit board 16a～16c to be placed within the relative sweep interval based on those belts.
Then, after circuit board 16a～16c to be measured was brought to the position at ray machine group 40 places, ray machine group 40 can obtain the scan-image of circuit board 16a～16c respectively, so that judge according to each sweep interval 12a～12c.So, controller just can be considered as single circuit board by the scan-image that each sweep interval 12a～12c is obtained, and carry out the datum hole contraposition in regular turn, rotation, displacement supervisor, compare again and judge and be presented on the screen.Which sheet circuit board the user just can clearly tell from the screen information such as bad hole, bad position.
By the detailed description of above preferred embodiment, hope can be known the feature and spirit of describing the present invention more, and is not to come the present invention's category is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain in the category of claim of being arranged in of various changes and tool equality institute of the present invention desire application.
