SOLDERING & DISPENSING Volumetric dispensing Solutions

From concept to turnkey solutions Unitechnologies SA, with its mta® brand, is an expert in small quantity volumetric dispensing processes based on standardized platforms. The product range includes components, standalone systems, semi-automatic table-top robots and entirely automatic production cells or lines. Thanks to a complete infrastructure, trials can be carried out on samples using all proven mta® dispensing techniques in the company’s test laboratories. Once the mta® technique has been validated, a detailed quotation is established with the proposed standard machine adapted to the...

Volumetric dispensing The mta® high-precision volumetric dispensers offer the most accurate volume control available in the fluid dispensing industry. They enable perfect repeatability of micro-volumes to be dispensed starting with 0.1 mm³. The pumping unit maintains accuracy in the most demanding of circumstances independently from changes of temperature, viscosity or deposit size. The mta® dispensers are based on a piston that moves within the dispensing chamber to deliver an exact quantity of fluid through the nozzle. The working principle is described on page 5. Deposit of...

Pump working principles The basic working principles of the pump combines a linear movement to define the quantity of material to be dispensed (see 2 and 4 in the picture on the right) and a rotating movement (see 3 in the picture) to transfer the material from the pump input to its output. The accurate pump assembly can be divided into different leak rates in order to be perfectly adapted to different types of material characteristics. This solution is highly precise and always volumetric. Picture legends: 1. Home position, 2. Filling stroke, 3. Rotation, 4. Dispensing stroke and snuff...

SOLDERING & DISPENSING The PC controlled MRC500 standard robotic cell can be used for semi or fully automatic operations of volumetric dispensing operations. The MRC500 can be equipped with all the established mta® dispensing techniques described on the previous pages. The 3 axes of the MRC500 are fully programmable through the mta® MotionEditor software including dispensing parameters such as: - Volume to be dispensed, dispensing speed, mixing ratio as well as other related dispensing parameters e.g. unlimited quantity of points, linear or circular beads. Thanks to its flexible and modular...

The PC controlled TR300 standard table-top robot can be used for semi-automatic operations of volumetric dispensing operations. The increasing requirements for processes in terms of quality, precision and repeatability lead to a similar increase in the necessary level of automation. However, when production batches are small or products widely dissimilar, the cost of sophisticated equipment can place automation beyond the reach of many would-be users. The TR300 combines the necessary flexibility with the required high levels of process quality and repeatability, all at reasonable cost. The...
