201249586 六、發明說明： 【發明所屬之技術領域】 [⑽1] 本發明與加工機有關，尤指一種可對多個工件進行定位 校準之加工機。 【先前技術】 [0002] 按，習用之電腦數值控制加工機（Computer Nu merical Control ， CNC) 乃執行使用者所輸入之程式 而自動對工件進行預設路徑之加工，而在進行加工之前 ，加工機必須先對工件之位置進行校準，確認工件之位 置後，才能開始加工工件，以確保工件能被正確加工。 [0003] 而習用之加工機若用於電路板之加工作業，因電路 板之製造無須要求電路板邊緣之平整性，故於一大片電 路板上區隔出數個加工區域，而在加工完成後再行切割 成小片之電路板進行封裝，如此在加工前的工件位置校 準作業上，只須對一大片之工件進行位置校準。 [0004] 然而，加工機若用於對產品之外形有嚴格要求之工 件上時，繼續使用上述的作業流程則還須多一道工件修 邊的步驟，無論在加工機程式之編寫或加工所需之時間 上，皆為成本提高之因素。故為降低成本，而令工件於 甫製造出來之時即為單一之個體，僅須對其進行必要之 加工而不須再切割或修邊，可省去不少步驟及成本。惟 如此一來，對於習用一次僅能對一個工件進行定位及加 工之加工機而言，又將多付出不少時間成本，實有改進 之必要。 [0005] 100120088 據此，如何改進上述問題並提供一種可多工件對位 表單編號A0101 第3頁/共12頁 1002033981-0 201249586 之加工.201249586 VI. Description of the invention: [Technical field to which the invention pertains] [(10) 1] The present invention relates to a processing machine, and more particularly to a processing machine capable of positioning and calibrating a plurality of workpieces. [Prior Art] [0002] According to the computer numerical control machine (CNC), the computer automatically performs the preset path processing on the workpiece by executing the program input by the user, and processes it before processing. The machine must first calibrate the position of the workpiece to confirm the position of the workpiece before starting to machine the workpiece to ensure that the workpiece can be processed correctly. [0003] If the conventional processing machine is used for the processing of the circuit board, since the manufacturing of the circuit board does not require the flatness of the edge of the circuit board, a plurality of processing areas are separated on a large circuit board, and the processing is completed. After that, the circuit board is cut into small pieces for packaging, so that only a large piece of workpiece needs to be positionally calibrated in the workpiece position calibration work before processing. [0004] However, if the processing machine is used on a workpiece that has strict requirements on the product, the use of the above-mentioned work flow requires an additional step of trimming the workpiece, regardless of the preparation or processing of the processing program. In terms of time, it is a factor of cost increase. Therefore, in order to reduce the cost, the workpiece is a single individual at the time of manufacture, and only necessary processing is required without cutting or trimming, which saves a lot of steps and costs. However, in the case of a processing machine that can only position and process one workpiece at a time, it will cost a lot of time and it is necessary to improve.

A photographing unit i is disposed on one of the cutting spindles and displaced with the cutting spindle, and images of the cutting spindle are photographed one by one. The central processing unit 2 includes an image recognition unit 2 1 , a recording unit 22 , and a maintenance execution program 2 3 , wherein the axe recognition unit 21 is electrically connected to the photographing unit 1 and receives the form number. A0101 1002033981-0 [0017] 201249586 _ 1 The image signal is captured, and the target in the image can be identified one by one: the 4 different coordinates are used and the recording unit 2 2 records the coordinates of the group of the image recognition unit The value is transferred to the machining execution program 2 3, and the machining execution program 2 3 sends the machining execution command. [0019] An input interface 4 is electrically connected to the p L C 3, and an instruction and a program for controlling the P L C 3 can be input through the input interface 4. In the actual use of the present invention, first, in the workpiece positioning stage, the marked workpieces are placed on the placement portions of the processing platform, and since the workpieces of the placement portions are not necessarily placed at the correct preset positions, The PLC 〇3 first controls the cutting spindle to take the position of the photographic unit (4) above the placement parts and capture an image of the workpiece on the placement portion to form an image signal, and the image of the camera 1 (4) is transmitted to the camera. The towel processing the image recognition unit 2 i in the early stage 2 to perform the identification of the marked position on the workpiece to obtain the error value between the actual position and the preset position of the guard, and then calculate the coordinate value of the actual position of the workpiece, the coordinate value of the money Transfer to the recording material 2, after the position of the workpiece on each placement portion is confirmed and recorded, the recording unit 2 2 transfers the actual position of the workpiece to the processing in the central processing unit W Executing the program 23, then the processing execution program 2 3a a guest τΛί· ^ 传送 transmits the actual position coordinate value information of each workpiece to the PLC 3, 兮τ ^. 7忒P L C 3 controls the cutting spindle displacement to this coordinate value' and uses its arrogant t dan as the machining start coordinate to ensure the positive discability of the workpiece. [0020] After the coordinate value of the actual position of the cow 100120088, the cutting main (4) of the photographing unit can be controlled by the PLC3! Displace to the coordinate value, by the rhyme n-n I. „A〇1〇I , '早 701 re-image and form another form number Α0Ι0Ι page β / page 6 / total 12 pages 1002033981-0 201249586 image The signal recognition unit 2 1 determines whether the position of the coordinate value is the actual position of the workpiece for the identification of the image signal, and if not, repeats the above steps until it is confirmed as the actual position of the workpiece, so that it is more certain The actual position of the workpiece without affecting the correctness of the machining due to the coordinate error. [0021] Ο After confirming and adjusting the machining start position of the cutting spindle, the PLC 3 then controls the cutting with its pre-entered machining program The spindle cuts each workpiece one by one, and if there are several machining stages in the machining process, after all the workpieces are processed in one stage, the cutting spindle replaces the other tool for the next stage processing until all The processing stage is completed. [0022] ❹ In addition, in the workpiece positioning stage, the p LC 3 controls the cutting spindle to carry the photographing unit 1 above the placement parts When the image of the workpiece position is photographed, if there is no mark for identification in the range of the photographing unit 1 in a certain placement portion, it means that the position of the workpiece on the placement portion is too far from the preset position, so that it cannot be corrected. Or, even if the workpiece is not placed, the image recognition unit 21 determines that the position of the placement portion is wrong, and transmits the information to the recording unit 2 2 and the processing execution program 2 3, and the processing execution program 2 3 Then, in the workpiece processing stage, the PLC 3 controls the cutting spindle to skip the erroneous placement portion to save working time. However, the disclosure of the above embodiments is for explaining the present invention, and is not intended to limit the present invention. Therefore, the change of the numerical value or the replacement of the equivalent component should still belong to the scope of this creation. 100120088 Form No. 1010101 Page 7 / Total 12 Page 1002033981-0 [0023] 201249586 [0024] In summary, the familiarity can be made.
