Machine vision inspection systems to transform production
Vision systems are a great way to achieve a leaner, more cost effective process that can transform your production. Have you ever thought about how they could make a significant difference to your workplace?
When it comes to vision solutions, you want a fast, flexible and reliable way to improve your inspection process. This is achieved by implementing the a tailormade visions system. Something that we specialise in here at Adbro Controls Ltd.
The adaptable technology can be applied to many different working environments, regardless of industry sector or materials used. Offering it’s users the freedom to set predefined parameters for inspection, delivering a more efficient monitoring process, thus providing accurate data logging for the end user.
Here at Adbro Controls, we partner with the best vision and software companies within the industry. By doing so we can provide you with a bespoke, high quality, automated inspection system that meets your exact needs.
What are the different approaches to vision technology?
Contactless inspection of critical dimensions can be achieved often without any breaks in production. This is used to ensure quality standards are met, support preventative maintenance through machine performance indicators, provide closed loop control, or guide the alignment of later steps in the assembly process.
Almost every industry can benefit from inspection measurement systems. Examples of where such a system can be used:
Food & Beverage Production
The completeness (missing components, correct position and orientation) and quantity of items can be checked. This is one of many vital steps in quality control in most if not all businesses, alongside ensuring parts are assembled correctly before they can be despatched onto the end customer.
This particular type of vision technology is often integrated with pick and place systems.
Incorrect positioning can be detected, allowing process equipment to adjust accordingly to rectify or remove the product.
Location tracking also allows for the prediction of future motion changes. We can program the process equipment to react appropriately should this occur.
When products do not meet the standard set, the quality of the product decreases.
Defect detection is an ideal solution for those looking to detect anomalies in their product and remove them from the process line.
Defects such as size, colour variation, unwanted marks or scratches can be detected.
A vision system that can detect when an item is out of specification can be a vital component to your inspection process, its beneficial to those looking to obtain a high level of quality control.
The question is, what is the most suitable method to then remove the faulty item?
Dependent on your preference, this method can be intrusive (using a divert gate) or non intrusive (using a pneumatic blower). The positioning of a reject gate can vary. You have the option for it to either be on the side or the bottom of the process line.
Push up Reject
This is where the defective item is pushed upwards onto a perpendicular reject conveyor separate from the main process line.
Pick up & Remove
Using a mechanical device (such as a robot, linear actuator) the defective item can be removed completely from the process line.
The environment has an important part to play in an effective vision system.
There are various factors that can have an effect on a vision system’s performance. Some of the main things to consider are ambient lighting changes and machine positioning. In many cases shrouding the light source and vision camera can overcome issues caused. This however is not always practically possible, dependent on the requirement and design.
When situations like this occur, we look to Artificial Intelligence to give us a helping hand. We can use this technology to record and log what is considered a ‘good’ and ‘bad’ image from your process. Our system will then use these images as a reference when performing quality/inspection checks. It is programmed in such a way that regardless of any environmental changes that may occur, there is a clear reference of what is considered acceptable.
Adbro Controls vision project procedure
We pride ourselves in being able to offer you bespoke vision systems that will meet your exact requirements. With so many years in the process industry, we have the knowledge and experience to consult with you as to what is best for your business.
After contacting us with your requirement, a dedicated vision engineer will get in touch to discuss your needs in further detail. To enable us to advise the best solutions for you, a site visit can be scheduled where we can observe your process in situ.
In order to assist with the development side of the project, where possible we like to obtain product samples to help aid tests carried out in house. These tests will include the use of a range of equipment including cameras, lenses and lighting.
Results obtained by these test studies will enable us to determine the best solution for your needs and allow us to advise the associated costs.
