Description
本創作是有關於一種自動化檢查，特別是指一種用於將大量螺絲中的良品與瑕疵品分開的螺絲自動化檢查的裝置。This creation is about an automatic inspection, especially a device for automatic inspection of screws that separates good and defective products from a large number of screws.
在螺絲製造產業中，當螺絲加工完成後，必須檢查螺絲外觀來找出瑕疵品，而傳統方法是透過人工以肉眼判斷是否有瑕疵品，並以人工方式挑出，以將瑕疵品與良品分開。然而，由於螺絲為大量生產，用肉眼判斷以及利用人工分類，費時費工，而且容易有判斷標準不一致的問題。另一方面，市面上雖有利用2D平面攝影技術來擷取螺絲外觀影像以檢測出瑕疵品，但在檢測過程中都需要先將每一螺絲安置於治具中才能進行拍攝，不僅麻煩，且治具與螺絲的規格需對應，當要檢測不同規格的螺絲時，就要更換治具，造成不便。而且後續要取出瑕疵品時，還是要透過人工方式拾取，因此仍有費時費工的問題，以上缺失有待改良。In the screw manufacturing industry, after the screw processing is completed, the appearance of the screw must be checked to find the defective product. The traditional method is to manually judge whether there is a defective product and to pick it out manually to separate the defective product from the good product. . However, because screws are mass-produced, judging with the naked eye and using manual classification are time-consuming and labor-intensive, and are prone to the problem of inconsistent judgment standards. On the other hand, although 2D planar photography technology is used on the market to capture the appearance of screws to detect defects, it is necessary to place each screw in a fixture before shooting, which is not only troublesome, but also The specifications of the jig and the screw need to correspond. When testing screws of different specifications, the jig must be replaced, causing inconvenience. Moreover, when the defective products are subsequently taken out, they must still be picked up manually, so there is still a problem of time and labor. The above defects need to be improved.
因此，本創作之目的，即在提供一種能克服先前技術的至少一個缺點的螺絲自動化檢查裝置。Therefore, the purpose of the present invention is to provide an automatic screw inspection device which can overcome at least one of the disadvantages of the prior art.

參閱圖1、2、3，本創作螺絲自動化檢查裝置之一實施例，適用於傳送大量的螺絲1，並從中檢測與挑出有瑕疵的瑕疵螺絲1’。本實施例的螺絲自動化檢查裝置包含一進料單元2、一輸送單元3、一3D檢測單元4、一傳動單元5，及一容器6。Referring to Figs. 1, 2, and 3, an embodiment of the automatic screw inspection device is suitable for transferring a large number of screws 1 and detecting and picking out defective screws 1 'from them. The automatic screw inspection device of this embodiment includes a feeding unit 2, a conveying unit 3, a 3D detection unit 4, a transmission unit 5, and a container 6.
該進料單元2大致為漏斗狀，並包括一位於頂部且適用於供螺絲1投入的進料口21，以及一位於底部且適用於供螺絲1釋放出的出料口22。The feeding unit 2 is substantially funnel-shaped and includes a feeding port 21 at the top and suitable for the screw 1 to be input, and a discharging port 22 at the bottom and suitable for the screw 1 to be released.
該輸送單元3位於該進料單元2的下游，並適用於承接自該出料口22而來的螺絲1。本實施例的輸送單元3包括一具有震動功能而能將該等螺絲1震動散開的輸送帶31。該輸送帶31沿一輸送方向T延伸，並能持續朝該輸送方向T輸送該等螺絲1，在輸送時進行震動以使螺絲1散開。該輸送帶31具有數個形成於頂面且彼此間隔的凹槽311，該等凹槽311適用於容置該等螺絲1。The conveying unit 3 is located downstream of the feeding unit 2, and is suitable for receiving screws 1 from the discharging port 22. The conveying unit 3 of this embodiment includes a conveying belt 31 having a vibration function and capable of shaking the screws 1 apart. The conveying belt 31 extends along a conveying direction T, and can continuously convey the screws 1 toward the conveying direction T. When conveying, the screws 1 are shaken to spread the screws 1 apart. The conveyor belt 31 has a plurality of grooves 311 formed on the top surface and spaced from each other. The grooves 311 are suitable for receiving the screws 1.
該3D檢測單元4包括數個影像擷取模組41、一訊號連接該等影像擷取模組41的比對模組42，及一訊號連接該比對模組42的控制模組43。本實施例的影像擷取模組41為具有拍照與攝影功能的攝影機，數量為三台，該等影像擷取模組41適用於擷取每一螺絲1的外觀影像，且該等影像擷取模組41的架設角度、方位有所不同，藉此使該等影像擷取模組41擷取到的影像可搭配構成螺絲1的3D立體影像。該比對模組42內建儲存有一標準影像，該標準影像為標準規格的螺絲1外觀影像。該比對模組42適用於將該等影像擷取模組41擷取到的每一螺絲1的3D立體影像與該標準影像進行比對，以檢測出瑕疵螺絲1’。具體來說，當任一螺絲1的3D立體影像與該標準影像比對後，若影像差異度小於或等於一門檻值，該螺絲1即為良品，若影像差異度大於該門檻值，該螺絲1即為瑕疵品。所述門檻值可預先設定於該比對模組42中。該控制模組43用於接收該比對模組42的比對結果，並能將瑕疵螺絲1’的位置定位出來。The 3D detection unit 4 includes a plurality of image capture modules 41, a comparison module 42 connected to the image capture modules 41 by a signal, and a control module 43 connected to the comparison module 42 by a signal. The image capturing module 41 in this embodiment is a camera with photographing and photographing functions, and the number is three. The image capturing modules 41 are suitable for capturing the appearance image of each screw 1, and the image capturing The installation angles and orientations of the modules 41 are different, so that the images captured by the image capturing modules 41 can be matched with the 3D stereo images constituting the screw 1. A standard image is stored in the comparison module 42, and the standard image is an appearance image of the screw 1 of a standard specification. The comparison module 42 is adapted to compare the 3D stereoscopic image of each screw 1 captured by the image capture modules 41 with the standard image to detect a defective screw 1 '. Specifically, after comparing the 3D stereoscopic image of any screw 1 with the standard image, if the image difference is less than or equal to a threshold value, the screw 1 is a good product, and if the image difference is greater than the threshold value, the screw 1 is defective. The threshold value can be set in the comparison module 42 in advance. The control module 43 is used for receiving the comparison result of the comparison module 42 and can position the position of the defective screw 1 '.
該傳動單元5訊號連接該控制模組43，並能受到該控制模組43控制而移動到瑕疵螺絲1’處，以將瑕疵螺絲1’拾起。具體而言，本實施例的傳動單元5包括一機械手臂51，可將瑕疵螺絲1’拾起並置入該容器6中。該容器6位於該傳動單元5一側，並適用於容置該傳動單元5輸送而來的瑕疵螺絲1’。The transmission unit 5 signal is connected to the control module 43 and can be controlled by the control module 43 to move to the defective screw 1 'to pick up the defective screw 1'. Specifically, the transmission unit 5 of this embodiment includes a robot arm 51, which can pick up the defective screw 1 'and place it in the container 6. The container 6 is located on one side of the transmission unit 5 and is suitable for receiving defective screws 1 'transported by the transmission unit 5.
本實施例使用時，加工完成的大量螺絲1自該進料單元2落到該輸送單元3上，該輸送單元3的輸送帶31可被控制震動而將該等螺絲1震散開，且由於該輸送單元3設有該等凹槽311，因此被震散開的螺絲1會自動置入該等凹槽311，如此可使各螺絲1定位。接著該3D檢測單元4擷取每一螺絲1的影像，並進行影像比對後，即可找出有瑕疵螺絲1’。後續該3D檢測單元4的該控制模組43控制該傳動單元5移動，以將瑕疵螺絲1’拾起並投入該容器6中，如此即可挑出瑕疵螺絲1’，將瑕疵螺絲1’與良品分開。When this embodiment is used, a large number of processed screws 1 fall from the feeding unit 2 to the conveying unit 3, and the conveying belt 31 of the conveying unit 3 can be controlled to shake and spread the screws 1 apart. The conveying unit 3 is provided with such grooves 311, so the screws 1 scattered by the vibration are automatically placed in the grooves 311, so that the screws 1 can be positioned. Then, the 3D detection unit 4 captures an image of each screw 1 and performs image comparison to find a defective screw 1 '. Subsequently, the control module 43 of the 3D detection unit 4 controls the transmission unit 5 to move and pick up the defective screw 1 'and put it into the container 6, so that the defective screw 1' can be picked out, and the defective screw 1 'and Good quality separated.
需要說明的是，上述輸送過程中，並非以所有螺絲1都要被震動到該輸送單元3的凹槽311為限制，因為部分螺絲1仍有可能位於該輸送單元3頂面未形成有凹槽311處。此外，該輸送單元3不以具有震動功能為必要，也不以設置凹槽311為必要，如此同樣能達到輸送螺絲1的功能。It should be noted that, in the above-mentioned conveying process, not all screws 1 must be shaken to the groove 311 of the conveying unit 3 as a limitation, because some screws 1 may still be located on the top surface of the conveying unit 3 and no groove is formed 311. In addition, the conveying unit 3 does not need to have a vibration function, nor does it need to provide a groove 311, so that the function of the conveying screw 1 can also be achieved.
綜上所述，由於本創作的影像擷取模組41數量為數個，可搭配產生螺絲1的3D影像。取像時可直接進行拍攝，不需要如傳統2D平面攝影需要先將螺絲1安置於治具中，因此本創作於影像比對上更加精準且快速，有助於提升瑕疵螺絲1’之篩選速度。本創作為自動化裝置，該3D檢測單元4進行檢測後，能自動控制該傳動單元5拾起瑕疵螺絲1’，相對於傳統以人工檢測篩選的方式而言，本創作具有篩選快速、精準之優點，並且可以節省人力。In summary, since the number of image capture modules 41 created in this creation is several, they can be used together to generate a 3D image of the screw 1. You can shoot directly when you take the image. You do n’t need to place the screw 1 in the fixture, as in traditional 2D flat photography. Therefore, this creation is more accurate and faster than the image comparison, which helps to improve the screening speed of the defective screw 1 '. . This creation is an automated device. After the 3D detection unit 4 detects, it can automatically control the transmission unit 5 to pick up the defective screw 1 '. Compared with the traditional method of manual detection and screening, this creation has the advantages of fast and accurate screening. And can save manpower.
