VISION SYSTEM PAYS FOR ITSELF IN ONE WEEK BY PREVENTING TWO COSTLY DEFECTS

Pontiac Coil manufactures electrical coils, solenoids, and electromechanical devices for automotive, trucking, mobile equipment, medical, information technology and telecommunications applications. In building a fuel stator for a diesel engine, the company has long manually inspected every part to ensure that the lead tower cap had been attached with pins or screws and that the lead towers have been soldered. The company is penalized $2,000 for any defect on this part. Pontiac Coil previously used vision systems that cost $10,700 for similar applications but asked a vision systems distributor if they could provide a more cost-effective solution.

The Vision Traceability Group (VTG), a certified solutions provider of machine vision solutions that is a division of McNaughton-McKay Electric Company, proposed using a Cognex In-Sight® Micro 1050 vision system that costs about $3,700. Rob Osgood, Manufacturing Engineer for Pontiac Coil, developed the application using the vision sensor’s graphical user interface in one week and installed it on the line in only 90 minutes. “The In-Sight vision system has demonstrated its ability to flawlessly inspect several different part numbers,” Osgood said. “In its first full week of operation, it detected two defects, more than paying for itself.”

Manufacturing fuel injection stators

Quality assurance and process control are the foundation of manufacturing at Pontiac Coil. Customers include Delphi, Eaton, Visteon, Cummins, American Axle, Behr, Honeywell, Husco, Teleflex, Bosch, Usui and Ogura. Pontiac Coil employs 340 people and is headquartered in Clarkston, MI, with additional manufacturing facilities in Searcy, AR, and Nottingham, UK.

Most diesel engines use fuel injectors to deliver an atomized fuel charge to the engine cylinders. An electronic timing circuit delivers precisely timed electrical pulses for operation of the fuel injector. These pulses are delivered to a solenoid stator assembly which generates magnetic forces to actuate a solenoid plunger mounted in the fuel injector that controls the injection of fuel into each engine cylinder. The housing of the solenoid stator assembly protects the internal electrical components and locates them precisely in relation to the reciprocating solenoid plunger.

Pontiac Coil builds several types of stators for diesel engines used on heavy trucks. These stators are inspected on a dial machine that checks for high potential (hipot) conditions by applying a high voltage and making sure it does not penetrate the shell. The machine also performs leak testing and laser inspection of threads inside the body. Parts that pass all tests are then laser etched with a unique serial number. The dial machine is manually loaded and unloaded. In the past, the only manual inspection operation was to check the fasteners on the stator.

Two different types of fasteners—pins and star head screws—are used on the two different types of stators inspected on this line and the company needs to ensure that the correct screw is present. Each terminal also needs to be coated with solder so that it makes a good connection with the housing. Also, there are lobes located on the housing to the left and right of a cavity that could potentially be broken off, so the stators also need to be inspected for their presence. Pontiac Coil has used a number of costly vision systems in similar applications and consultants are typically needed to configure these complex systems.

Feasibility study

Tim McLennan, sales engineer for VTG, visited Pontiac Coil and examined the application. He performed a study to evaluating the feasibility of using a much less expensive Cognex vision solution to inspect the part. McLennan brought sample parts back to the company’s vision lab and Jim Witherspoon, Application Engineer for VTG, performed the feasibility study. After experimenting with the application in the lab, Witherspoon concluded that lighting is the key to this application. “Various direct ring lights can be attempted but the CCS High Intensity ring light makes this application very robust,” Witherspoon’s report concluded. “If there is a solder then the tips glow a bright white. If the solder is missing then the tips remain dark. The pins and screw verification also works very well with the prescribed lighting.”

Witherspoon recommended the Cognex In-Sight Micro 1050 vision system because it provides both EasyBuilder® and spreadsheet application development interfaces. Cognex In-Sight Micro vision systems enable powerful vision applications using a small self-contained package available at an economical cost. Additionally, In-Sight vision systems feature the EasyBuilder interface that walks the user through the process of configuring the vision application step by step. The In-Sight enclosure is only 30mm x 30mm x 60mm and provides 640 x 480 (VGA) resolution.

In-Sight Micro vision systems are the size of a remote-head camera so they are ideal for mounting in very tight spaces on robots, production lines and machinery. In addition to their small size, they provide flexible mounting capability with a unique non-linear calibration tool that enables mounting at angles of up to 45-degrees for hard-to-reach applications. They also offer an Ethernet output that simplifies the task of interfacing the vision system and, in some applications, eliminates the expense of a programmable logic controller (PLC) by communicating directly with the production system.

Developing the vision application

The feasibility study demonstrated that the In-Sight vision system could identify good parts from bad parts,” said Rob Osgood, Manufacturing Engineer for Pontiac Coil. “I took on the task of developing the application and integrating the vision system into our production system.” Osgood started off by mounting the vision system and connecting it by an Ethernet cable to the network switch. The vision system is powered by a Power over Ethernet (PoE) adaptor. He used the lighting and the lens recommended by VTG. Osgood configured the vision system with an IP address on the network that was immediately recognized by the Allen Bradley PLC that controls the production system PLC. The EasyBuilder interface automatically generates the Allen Bradley ControlLogix commands needed to communicate with the PLC.

Osgood used the spreadsheet functionality to perform several filtering operations, including binarization and stretching, for each screw position. He used a series of contrast tools to search for each of the fasteners that should be present in the stator housing. The contrast tools measure the number of light pixels relative to the dark pixels within each area where each of the five screws and two lobes are supposed to be located. The next step after verifying the presence of the screws or lobes is the use of pattern tools to check the type of each fastener on the stator.

The presence of solder is inspected simply by binarizing the image of each terminal and measuring the grey scale. Osgood identified the lobes by searching for the plastic circle on each lobe and verifying its diameter. He used EasyBuilder’s point-and-click communications setup to configure the vision system to send inspection results to the PLC after each inspection. In the deployment mode, color tools graphics, a results table and a filmstrip enable to the operator and maintenance staff to review images in order to verify the identification of bad parts and troubleshoot the application.

“The vision application has helped us improve quality while reducing manpower on the inspection line,” Osgood concluded. “The vision system’s relatively low cost was easy to justify since we are penalized $2,000 for any defect. The vision system has operated for six months and in this time it has never passed a bad part nor failed a good part. The result is that we have been able to free up a manual inspector on the line for a more proactive assignment and run the inspection system without operators except for loading and unloading parts. The programmability of the vision system means that we can easily modify the program to compensate for design or process changes. Most important of all, we are confident that we have no fastener-related defects.”

    五、光谱共焦传感器测量厚度的局限性及解决措施5.1 局限性分析5.1.1 测量范围限制光谱共焦传感器的测量范围相对有限,一般在几毫米到几十毫米之间。这是由于其测量原理基于色散物镜对不同波长光的聚焦特性,测量范围主要取决于色散物镜的轴向色差范围以及光谱仪的工作波段。在实际应用中,对于一些大尺寸物体的厚度测量,如厚壁管材、大型板材等,可能需要多次测量拼接数据,增加了测量的复杂性和误差来源。例如,在测量厚度超过传感器量程的大型金属板材时,需要移动传感器进行多次测量,然后将测量数据进行拼接处理,但在拼接过程中可能会因测量位置的定位误差、测量角度的变化等因素导致测量结果的不准确。5.1.2 对被测物体表面状态的要求虽然光谱共焦传感器对多种材料具有良好的适用性,但被测物体表面的粗糙度、平整度等因素仍会对测量精度产生一定影响。当被测物体表面粗糙度较大时,表面的微观起伏会导致反射光的散射和漫反射增强,使得反射光的强度分布不均匀,从而影响光谱仪对反射光波长的准确检测,导致测量误差增大。对于表面平整度较差的物体,如存在明显翘曲或弯曲的板材,会使传感器与物体表面的距离在不同位置发生变化,超出传感器的测量精度范围,进而影响厚度测量的准确性。例如,在测量表面粗糙的橡胶板材时,由于橡胶表面的微观纹理和不规则性,测量精度会明显下降,难以达到对光滑表面测量时的高精度水平。5.1.3 成本相对较高光谱共焦传感器作为...
