Description
本發明涉及電路板測試技術領域，尤其涉及一種兼具同步噴碼功能的電路板電測設備。 The invention relates to the technical field of circuit board testing, in particular to a circuit board electrical measuring device which has the function of synchronous coding.
電路板係電子產品中傳送電訊號的主要器件，在電路板的製作過程中，如內層線路蝕刻、外層線路蝕刻、鍍孔等製程後均需對電路基板以及電路板成品進行電性測試(簡稱為電測)，以避免電路基板及電路板成品出現短路、斷路及漏電等電性能的缺陷。該電測係藉由測試電路板(電路基板)電氣相連的同一網點內各電測點如焊點間的電阻值的大小，以判斷電路板(電路基板)的電導通性及絕緣性，請參閱文獻Yiu-Wing Leung, A Signal Path Grouping Algorithm for Fast Detection of Short Circuits on Printed Circuit Boards, IEEE Transactions on Instrumentation and Measurement, Vol 43. No. 1, p288-292, February 1994。 Circuit board is the main component for transmitting electrical signals in electronic products. During the manufacturing process of the circuit board, such as inner layer etching, outer layer etching, and plate plating, electrical testing of the circuit substrate and the finished circuit board is required. Referred to as electrical measurement), to avoid shortcomings such as short circuit, open circuit and leakage of circuit board and circuit board. The electrical measurement system determines the electrical conductivity and insulation of the circuit board (circuit substrate) by measuring the resistance value between each electrical measurement point in the same network point of the test circuit board (circuit board), such as the solder joint. See Yiu-Wing Leung, A Signal Path Grouping Algorithm for Fast Detection of Short Circuits on Printed Circuit Boards, IEEE Transactions on Instrumentation and Measurement, Vol 43. No. 1, p288-292, February 1994.
待電測完成後，需將電測合格的電路板搬運至下一製程即噴碼製程，利用噴碼設備對每個電路板噴印獨一無二的標示碼以示區分。惟，於搬運前，電測不合格的電路板與合格電路板僅以放置位置不同加以區別。由此，很可能導致操作人員將不合格品亦搬至噴碼設備處噴印標示碼，與合格電路板相互混淆。且，將電路板搬運至該噴碼設備消耗大量時間，不利於提高生產效率。 After the electrical test is completed, the circuit board that has passed the electrical test needs to be transported to the next process, that is, the inkjet process, and the unique marking code is printed on each circuit board by the coding device to distinguish it. However, before the transfer, the circuit board that fails the electrical test and the qualified circuit board are distinguished only by the placement position. As a result, it is very likely that the operator will move the non-conforming product to the printing equipment to print the identification code, which is confused with the qualified circuit board. Moreover, transporting the circuit board to the inkjet device consumes a lot of time, which is not conducive to improving production efficiency.
有鑑於此，有必要提供一種具有同步噴碼功能的電測設備來提高生產精度及生產效率。 In view of this, it is necessary to provide an electrical measuring device with synchronous coding function to improve production precision and production efficiency.

The sensing component is configured to sense whether the circuit board after being tested by the electrical measuring part passes, and send the sensing result to the control part. The control unit is respectively connected to the sensing component and the printing component, and is configured to synchronously control the printing component to print the marking code only on the surface of the circuit board that is qualified by the electrical sensing according to the sensing result. The electric measuring device further comprises a defective board placing area, a qualified board placing area and a feeding mechanism, wherein the feeding mechanism is configured to respectively transport the circuit board electrically measured by the electric measuring part from the electric measuring part to the unqualified board The sensing part and the printing part are disposed between the electrical measuring part and the qualified board placing area.

The board is sensed during the process of the qualified board placement area 14 and the defective board placement area 13, and the sensing result is transmitted to the control section 40. The sensing member 30 can be a photoelectric switch or an image sensor commonly used in the art.
控制部40設於頂板11的承載面111，其分別與電測部20、感測件30及噴碼部50相連，用於根據電測部20的電測結果即合格/不合格控制感測件30相應地運作/不運作，並根據感測件30的感測結果同步控制噴碼部50僅噴碼於合格電路板表面。控制部40還可包括人機交互介面。 The control unit 40 is disposed on the bearing surface 111 of the top plate 11 and is respectively connected to the electrical measuring portion 20, the sensing member 30 and the printing portion 50, and is used for sensing/failure control sensing according to the electrical measurement result of the electrical measuring portion 20.

本技術方案的電測部100設有感測件30及與電測部20、感測件30相連的控制部40及噴碼部50，在電路板電測合格的同時實現同步噴印碼。與先前技術相比，採用該電測部100無需將電路板搬至相對電測設備單獨設置的噴碼設備，由此避免因人為錯誤而混淆不合格電路板及合格電路板，且大大提高了生產效率。 The electrical measuring unit 100 of the present invention is provided with a sensing component 30, a control unit 40 connected to the electrical measuring unit 20 and the sensing component 30, and a coding unit 50, and realizes a synchronous printing code while the circuit board is electrically tested. Compared with the prior art, the electric measuring unit 100 does not need to move the circuit board to the printing device separately provided with respect to the electric measuring device, thereby avoiding confusing the unqualified circuit board and the qualified circuit board due to human error, and greatly improving the Productivity.
此外，本實施例的控制部40可設置標示碼的預編電腦程式，該電腦程式對各電測合格電路板賦予一個唯一的標示碼，由此控制噴碼部50在各電測合格電路板表面噴印該唯一的標示碼。本實施例的電測設備100的結構並不限於此，如不設置固定件15，而將噴碼部50直接固定於安裝面112，且使其噴頭沿重力方向設置。控制部40可不設於頂板11，而採用本領域其他任何常用手段加以固定，電測部20、不合格板放置區13、固定件15及合格板放置區14之間的位置關係可按其他形式設置，只要將感測部30及噴碼部50設於電測部20及合格板放置區14之間，能感測電測合格的電路板並同步於該電路板表面噴碼即可。特別地，感測件30可一直開啟運作，即控制部40雖與感測件30相連，但並不控制感測件30是否運作，此時，若電測部20的電測結果表明為合格板，電測部20將該電測結果傳輸至控制部40，一旦輸料機構60將該電路板傳輸至感測件30能感測到的區域，感測件30將感測結果傳輸至控制部40，控制部40控制噴碼部50於該合格電路板表面噴印標示碼。此外，控制部40可不與電測部20相連，對應地，不合格板放置區13未設於電測部20及合格板 放置區14之間，此時，輸料機構60僅將經電測部20電測合格的電路板自電測部20經由感測件30輸送至合格板放置區14，由此實現只感測該合格電路板。 In addition, the control unit 40 of the embodiment may be provided with a pre-programmed computer program for designating a code, and the computer program assigns a unique identification code to each of the electrical test boards, thereby controlling the code portion 50 on each of the electrical test boards. The surface is printed with the unique identification code. The structure of the electrical measuring device 100 of the present embodiment is not limited thereto. If the fixing member 15 is not provided, the printing portion 50 is directly fixed to the mounting surface 112, and the head is disposed in the direction of gravity. The control unit 40 may not be disposed on the top plate 11, but may be fixed by any other conventional means in the art. The positional relationship between the electrical measuring portion 20, the defective plate placing area 13, the fixing member 15 and the qualified board placing area 14 may be in other forms. In the installation, the sensing unit 30 and the coding unit 50 are disposed between the electrical measurement unit 20 and the qualified board placement area 14, so that the circuit board that has passed the electrical measurement can be sensed and coded on the surface of the circuit board. In particular, the sensing component 30 can be always turned on, that is, the control unit 40 is connected to the sensing component 30, but does not control whether the sensing component 30 operates. At this time, if the electrical measurement result of the electrical measuring component 20 indicates that it is qualified. The board and the electrical measuring unit 20 transmit the electrical measurement result to the control unit 40. Once the feeding mechanism 60 transmits the circuit board to the area that the sensing unit 30 can sense, the sensing unit 30 transmits the sensing result to the control. In the portion 40, the control unit 40 controls the coding unit 50 to print an identification code on the surface of the qualified circuit board. In addition, the control unit 40 may not be connected to the electrical measurement unit 20, and correspondingly, the defective board placement area 13 is not disposed on the electrical measurement unit 20 and the qualified board. Between the placement areas 14 , at this time, the feeding mechanism 60 only transports the circuit board that has passed the electrical measurement by the electrical measurement unit 20 from the electrical measurement unit 20 to the qualified board placement area 14 via the sensing unit 30, thereby achieving sensing only. The qualified circuit board.
綜上所述，本發明確已符合發明專利之要件，遂依法提出專利申請。惟，以上所述者僅為本發明之較佳實施方式，自不能以此限制本案之申請專利範圍。舉凡熟悉本案技藝之人士爰依本發明之精神所作之等效修飾或變化，皆應涵蓋於以下申請專利範圍內。 In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law.
