為了詳細說明本發明之技術特點所在，茲舉以下之較佳實施例並配合圖式說明如後，其中：In order to explain the technical features of the present invention in detail, the following preferred embodiments are described in conjunction with the drawings as follows, wherein:
如第1圖至第6圖所示，本發明第一較佳實施例所提供之一種檢測開孔鋼板的定位方法，主要具有下列步驟：As shown in FIG. 1 to FIG. 6, a positioning method for detecting a perforated steel plate provided by the first preferred embodiment of the present invention mainly includes the following steps:
A)置入鋼板：如第2圖所示，將一鋼板11置入一檢測機台21；如第3圖所示，該鋼板11呈矩形且尺寸已知，且定義有一待檢測區域12，該待檢測區域12至少有部分的邊緣呈圓弧形，於本實施例中係以全部的邊緣呈圓弧形為例，亦即，以該待檢測區域12呈圓形為例，且該鋼板11具有複數開孔111位於該待檢測區域12內，該鋼板11還具有至少一基準孔14，該檢測機台21係與一電腦31電性連接。前述之電腦31可以是個人電腦，也可以是該檢測機台21本身的控制電腦。其中，定義該待檢測區域12之圓心為一實際圓心AO，該至少一基準孔14不位於該實際圓心AO，該實際圓心AO及該鋼板11之原點座標係以人工或電子的方式輸入至該檢測機台21的座標系。於本第一實施例中，該實際圓心AO係位於該鋼板11的中央，而該至少一基準孔14則位於待檢測區域12的邊緣。以一般狀況而言，待檢測區域12內通常是用來設置開孔111的有效區域而不會設置基準孔，因此，基準孔通常會設置在邊緣的位置。此外，於本第一實施例中，該至少一基準孔14在數量上係以四個為例，而呈等角分佈，以正Y軸為0度而言，係分佈於45度、135度、225度以及315度的位置。而在下述的步驟中，則都是以位於該待檢測區域12左下方(即225度)的這個基準孔14做為單一計算標的，進而做為定位的基礎。A) Inserting a steel plate: As shown in FIG. 2, a steel plate 11 is placed in a testing machine 21; as shown in FIG. 3, the steel plate 11 is rectangular and has a known size, and defines a region 12 to be tested. At least part of the edges of the area to be detected 12 are arc-shaped. In this embodiment, all edges are round-shaped. For example, the area to be detected 12 is circular, and the steel plate is an example. 11 has a plurality of openings 111 located in the area 12 to be inspected. The steel plate 11 also has at least one reference hole 14. The inspection machine 21 is electrically connected to a computer 31. The aforementioned computer 31 may be a personal computer or a control computer of the testing machine 21 itself. Wherein, the circle center of the area to be detected 12 is defined as an actual circle center AO, the at least one reference hole 14 is not located at the actual circle center AO, and the coordinates of the origin of the actual circle center AO and the steel plate 11 are manually or electronically input to The coordinate system of the detection machine 21. In the first embodiment, the actual circle center AO is located at the center of the steel plate 11, and the at least one reference hole 14 is located at the edge of the area 12 to be detected. In general, the area to be detected 12 is generally an effective area for setting the opening 111 without a reference hole. Therefore, the reference hole is usually located at the edge. In addition, in the first embodiment, the number of the at least one reference hole 14 is exemplified by four, and the distribution is an equiangular distribution, and when the positive Y axis is 0 degrees, it is distributed at 45 degrees and 135 degrees. , 225 degrees, and 315 degrees. In the following steps, the reference hole 14 located at the lower left (ie, 225 degrees) of the area to be detected 12 is used as a single calculation target, and then used as a basis for positioning.
B)輸入鋼板圖形檔：如第4圖所示，將一鋼板圖形檔41輸入至該電腦31，該鋼板圖形檔41具有該鋼板11的圖形座標系、各該開孔111的座標、該四個基準孔14的座標以及形狀上對應該待檢測區域12之一待檢測區域圖形資訊44，且該待檢測區域圖形資訊44之圓心係定義為虛擬圓心VO。B) Inputting a steel plate pattern file: As shown in FIG. 4, a steel plate pattern file 41 is input to the computer 31. The steel plate pattern file 41 has a graphic coordinate system of the steel plate 11, the coordinates of each of the openings 111, the four The coordinates of the reference holes 14 and the shape information corresponding to the to-be-detected area graphic information 44 of one of the to-be-detected areas 12 are defined as the virtual circle center VO.
C)重新定義該鋼板的圖形座標系：藉由該電腦31，於該鋼板圖形檔41中定義一X切線以及一Y切線切於該待檢測區域12之圓形邊緣，並將該X切線與該Y切線之交點定義為新原點LB，其中X切線平行於X軸，Y切線平行於Y軸。其中，由於該鋼板11的尺寸已知，可以得知其長為H、寬為W，利用該實際圓心AO位於該鋼板11中心的特性可以知道該實際圓心AO的座標為(W/2, H/2)，且由該待檢測區域圖形資訊44亦可得知其半徑r，因此，該X切線與該Y切線的交點LB其座標即為LB = (W/2 - r, H/2 - r)，其中，該鋼板11的圖形座標系的原始原點為左下角的點。接著，如第5圖所示，將該鋼板11的圖形座標系原點平移至該新原點LB，藉此即重新定義了該鋼板11的圖形座標系。C) Redefining the graphic coordinate system of the steel plate: by means of the computer 31, an X tangent line and a Y tangent line are defined in the steel plate graphic file 41 to cut the circular edge of the area 12 to be detected, and the X tangent line and The intersection of the Y tangent is defined as the new origin LB, where the X tangent is parallel to the X axis and the Y tangent is parallel to the Y axis. Among them, since the size of the steel plate 11 is known, it can be known that its length is H and width is W. Using the characteristics of the actual circle center AO located at the center of the steel plate 11, it can be known that the coordinates of the actual circle center AO are (W / 2, H / 2), and the radius r of the area to be detected can also be obtained from the graphic information 44 of the area to be detected. Therefore, the coordinate of the intersection point LB of the X tangent line and the Y tangent line is LB = (W / 2-r, H / 2- r), wherein the original origin of the graphic coordinate system of the steel plate 11 is a point in the lower left corner. Next, as shown in FIG. 5, the graphic coordinate system origin of the steel plate 11 is translated to the new origin LB, thereby redefining the graphic coordinate system of the steel plate 11.
D)座標系疊合：如第6圖所示，藉由該電腦31，將該鋼板圖形檔41的座標系與該檢測機台21的座標系疊合，疊合時係將該虛擬圓心VO與該實際圓心AO相重疊，其中，該檢測機台21的座標系之原點係位於該鋼板11的左下角。D) Coordinate system overlap: As shown in Fig. 6, the computer 31 superimposes the coordinate system of the steel plate pattern file 41 with the coordinate system of the inspection machine 21, and when superimposed, the virtual circle center VO It overlaps with the actual circle center AO, where the origin of the coordinate system of the detection machine 21 is located at the lower left corner of the steel plate 11.
E)取得該鋼板上的該基準孔相對於該鋼板之座標：藉由該鋼板11的長值H及寬值W、該待檢測區域12之半徑以及該基準孔14相對於該新原點LB的X軸及Y軸的距離，計算出該基準孔14在該鋼板11上的座標，位於左下角的該基準孔14之座標即為(W/2 – r + dx, H/2 – r + dy)，其中，關於前述該基準孔14相對於該新原點LB的X軸及Y軸的距離，由於在該鋼板圖形檔41內的該基準孔14的座標本就已知，因此可以得到該基準孔14相對於該新原點LB的X軸及Y軸的距離(dx, dy)。由於取得了該基準孔14在該鋼板11上的座標，因此在這個步驟即完成定位，該檢測機台21即可依此來對該鋼板11進行檢測。E) Obtain the coordinates of the reference hole on the steel plate relative to the steel plate: by the length H and width W of the steel plate 11, the radius of the area 12 to be detected, and the reference hole 14 relative to the new origin LB The distance between the X-axis and the Y-axis is used to calculate the coordinates of the reference hole 14 on the steel plate 11. The coordinates of the reference hole 14 at the lower left corner are (W / 2 – r + dx, H / 2 – r + dy ), Where the X-axis and Y-axis distances of the reference hole 14 with respect to the new origin LB are known, since the coordinates of the reference hole 14 in the steel plate pattern file 41 are known, the reference can be obtained The distance (dx, dy) of the X-axis and Y-axis of the hole 14 with respect to the new origin LB. Since the coordinates of the reference hole 14 on the steel plate 11 are obtained, the positioning is completed at this step, and the inspection machine 21 can detect the steel plate 11 accordingly.
須補充說明的是，前述步驟A)置入鋼板及步驟B)輸入鋼板圖形檔這兩個步驟，是可以在順序上對調的，並沒有先後順序的必要性。此外，步驟A)也可以改位於步驟C)與步驟D)之間。前述步驟可以這樣變化的原因在於，步驟A)的置入鋼板技術可以與步驟B)及C)的鋼板圖形檔及圖形座標系的處理技術分別進行，這兩個技術彼此間並沒有必然的先後關係。It must be added that the two steps of step A) placing the steel plate and step B) inputting the steel plate graphic file can be reversed in order, and there is no need for the order. In addition, step A) may also be located between step C) and step D). The reason why the foregoing steps can be changed in this way is that the technology of placing the steel plate in step A) can be performed separately from the processing technology of the steel plate pattern file and graphic coordinate system in steps B) and C). There is no necessary sequence between the two technologies. relationship.
由上可知，藉由取得該基準孔14在該鋼板11上的座標，本發明提供了開孔鋼板在檢測時的定位效果，而為先前技術中未明確揭露的技術。It can be known from the above that by obtaining the coordinates of the reference hole 14 on the steel plate 11, the present invention provides the positioning effect of the open-hole steel plate during detection, which is a technology not explicitly disclosed in the prior art.
請再參閱第7圖，本發明第二較佳實施例所提供之一種檢測開孔鋼板的定位方法，主要概同於前揭第一實施例，不同之處在於：Please refer to FIG. 7 again. A positioning method for detecting a perforated steel plate provided by the second preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that:
在步驟A)中，該實際圓心AO’不位於該鋼板11’的中央，而是與該鋼板11’的中央相距一預定距離。由於該實際圓心AO’不位於該鋼板11’的中心時，則鋼板廠商在出廠時即會提供一個相對於中心的偏移量(offset X, offset Y)，因此，這個偏移量即為前述之預定距離。In step A), the actual circle center AO 'is not located at the center of the steel plate 11', but is spaced a predetermined distance from the center of the steel plate 11 '. Since the actual center of circle AO 'is not located at the center of the steel plate 11', the steel plate manufacturer will provide an offset (offset X, offset Y) from the center when leaving the factory, so this offset is the aforementioned A predetermined distance.
而在步驟E)中，除了該鋼板11’的長寬值、該待檢測區域12’的半徑以及該基準孔14’相對於該新原點LB’的X軸及Y軸的距離以外，還需再加上前述的預定距離(即偏移量)的條件，來計算出該基準孔14’在該鋼板11’上的座標。In step E), in addition to the length and width of the steel plate 11 ', the radius of the region to be detected 12', and the distances of the reference hole 14 'from the X-axis and Y-axis of the new origin LB', it is necessary to Add the aforementioned conditions of the predetermined distance (ie, the offset) to calculate the coordinates of the reference hole 14 'on the steel plate 11'.
基於上述，在步驟A)中的實際圓心AO’座標就會成為(W/2 + offset X, H/2 + offset Y)，而在步驟C)中的該X切線與該Y切線交點LB’之座標即會變成為LB’ = (W/2 + offset X - r, H/2 + offset Y - r)。Based on the above, the actual circle center AO 'coordinate in step A) becomes (W / 2 + offset X, H / 2 + offset Y), and the intersection point of the X tangent line and the Y tangent line LB' in step C) The coordinates will become LB '= (W / 2 + offset X-r, H / 2 + offset Y-r).
而在步驟D)中，座標系疊合後，位於左下角的該基準孔14’之座標即為(W/2 + offset X – r + dx, H/2 + offset Y – r + dy)。In step D), after the coordinate system is superposed, the coordinates of the reference hole 14 'located in the lower left corner are (W / 2 + offset X-r + dx, H / 2 + offset Y-r + dy).
本第二實施例之其餘技術特徵以及所能達成的功效係概同於前揭第一實施例，容不再予贅述。The remaining technical features and achievable effects of the second embodiment are the same as those of the first embodiment, and will not be described again.

在步驟A)中，該待檢測區域12’’不呈圓形但邊緣有部分呈圓弧形，並定義該待檢測區域12’’之呈圓弧形邊緣所對應的圓心為該實際圓心AO’’。而該複數基準孔14’’係位於該待檢測區域12’’的呈圓弧形邊緣，且該待檢測區域12’’的呈圓形邊緣係涵蓋45度、135度、225度以及315度的位置。In step A), the area to be detected 12 "is not circular but some edges are arc-shaped, and the circle center corresponding to the arc-shaped edge of the area 12" to be detected is defined as the actual circle center AO ''. The plurality of reference holes 14 '' are located at the arc-shaped edges of the area 12 '' to be detected, and the circular edges of the area 12 '' to be detected cover 45 degrees, 135 degrees, 225 degrees, and 315 degrees s position.
在步驟C)中，該X切線以及該Y切線係切於依該待檢測區域12’’之圓弧形邊緣所定義出來的圓形的邊緣。In step C), the X tangent line and the Y tangent line are tangent to a circular edge defined by an arc-shaped edge of the region 12 '' to be detected.
在步驟E)中，由於在該鋼板圖形檔(圖中未示)內的該基準孔14’’的座標本就已知，因此可以得到該基準孔14’’相對於該新原點LB’’的X軸及Y軸的距離(dx, dy)。In step E), since the coordinates of the reference hole 14 "in the steel plate pattern file (not shown) are known, the reference hole 14" can be obtained relative to the new origin LB " The distance between the X-axis and Y-axis (dx, dy).
藉此，本第三實施例可以對非圓形的待檢測區域12’’提供定位效果，並不以第一實施例之圓形為限。Thus, the third embodiment can provide a positioning effect on the non-circular to-be-detected region 12 '', and is not limited to the circular shape of the first embodiment.
本第三實施例之其餘技術特徵及所能達成之功效均概同於前揭第一實施例，容不再予贅述。The remaining technical features and achievable effects of the third embodiment are the same as those of the first embodiment, and will not be described again.
