Custom Designed Automated Vision Inspection and Data Logging System for the Automotive Manufacturing Industry

An automotive Tier 1 manufacturing client approached MJ Engineering to design and install a quality system for the purpose of logging data and images from assemblies to provide product traceability. The system uses a 2D reader to read the unique serial identifier and then record the associated assembly data.

One part of the assembly process requires installing screws to specified torque requirements, the next stage is an automated vision based part inspection that checks to make sure the system is assembled correctly. Both the torque data and the vision image are logged to permanent files.

If the torque reading does not fall within tolerance or the vision inspection testing fails the part is not allowed to be packaged and an alarm will sound if an attempt is made to package failed parts.

Project Description

This automated Quality system reads and logs; 2D datamatrix codes, torque values and vision inspection pass/fail criteria.

Engineering of Continuous Miner for the Coal Mining Industry

MJ Engineering was approached by a coal mining company to engineer a new continuous miner. We were tasked with not only creating a miner that used the latest technology but also one that could be cost effective.

We began by designing the miner using Pro/ENGINEER software to create a 3D CAD model. Our design team also provided the client with a complete drawing package including a BOM and aided in selecting and procuring the OEM parts.

The continuous miner, which has steel with chromium carbide overlay in the conveying path, meets all MSHA and ATEX safety requirements. It is also capable of mining up to 14.5’ high coal and comes with a remote control pendant and the latest in motor control systems technology.

Finite Element Analysis of Shuttle Car Canopy for the Mining Industry

MJ Engineering was approached by a client to analyze the canopy design of a new mine shuttle car. The West Virginia-based customer asked us to verify that its shuttle car conformed to all current mining standards.

Using finite element analysis (FEA) we tested the shuttle car’s canopy and provided the needed engineering design to guarantee that the canopy conformed to MSHA standards and load ratings. Because of MJ Engineering’s outstanding design team, our customer was able to avoid the difficulties and cost of purchasing and maintaining FEA software and having to keep a professional engineer on staff. As always MJ Engineering also provided our client independent design advice and an industry leading level of customer support.

If you have any questions about this project or any of our other services please contact MJ Engineering or check out the details listed below.

Oral Syringe Filling Machine Cuts Time and Waste

A client in the medical industry needed a faster, more reliable method of filling oral syringes with liquid medications. Having human operators fill syringes one at a time was not efficient. That system led to inconsistencies between operators, and waste, due to air bubbles, causing inexact measurements of medicine.

To solve the client’s problem, MJ Engineering developed a machine that can automatically fill up to four syringes at once with the exact amount of fluid desired every time. It reduces or eliminates air bubbles and is faster and more precise than a person or machine filling one syringe at a time. Additionally, it is less complicated and expensive than a fully-automated, high-speed line of equipment.

With MJ Engineering’s machine, an operator can select a pre-programmed “recipe,” which contains information about the size of the syringe and other settings. When ready, the operator loads the bottles and syringes into the machine and presses a foot switch to start the automatic filling process.

MJ Engineering’s oral syringe filling machine can fill up to 400 syringes per hour, doubling the number filled by the client’s most experienced human operator.

In addition to its fast, easy, hands-free operation, the oral syringe filling machine developed by MJ Engineering uses safety light curtains and other methods to protect the operator, and it is made of stainless steel and aluminum for easy cleaning.
