2. MECHANICAL COMPONENTS
2.1. Instrument breakdown
The physical structure of the analyzer can be broken down as follows:
· Operating arm
- X guide.
- X carriage.
- Y carriage. This includes the spring and encoder of the Z carriage.
- Z carriage. This is the carriage carrying the thermostated needle. It includes the electronic needle conditioning
board.
- Cable carrier chains. These contain the electrical hoses of the arm and the dispensing tube.
· Dispensing system.
- Thermostated probe.
- Dispensing pump.
- Tubes and containers.
- Container level control scales.
- Racks tray with integrated washing station. This includes the electronic racks detection board.
- Washing pumps.
· Reactions rotor with integrated optical system.
- Thermostated rotor and photometric system. This contains the electronic photometric system board.
- Lighting system.
· Back covers
· Main cover hinges.
· Base. This houses the electronic boards of the microprocessor, the power supply and the front indicator.
· Housings.
- Back housing.
- Front housing. This houses the optical and rotor covers.
- Arm housing.
- Main cover.
The following is a brief description of each of the mechanical components that make up the analyzer.
2.2. Description of the mechanical components
2.2.1. Operating arm
This mechanism positions the dispensing needle appropriately during the preparation of the analyses. An encoder
checks the vertical movement of the needle and a spring automatically stops it from falling in the case of a power
cut. The dispensing tube and the electrical hoses of the arm are housed in cable carrier chains, which guide them
appropriately. A housing unit covers the Y and Z carriages.
