The Automatic Assembly Machine is a type of mechanical equipment that combines various parts of a product through methods such as tight fitting, snapping, screwing, bonding, riveting, and welding, to produce a finished or semi-finished product that meets predetermined dimensional accuracy and functionality requirements.
Popular definition
Manual assembly refers to the process of physically handling each component through tasks such as contacting, sorting, grabbing, moving, placing, and applying force.
On the other hand, automated assembly involves the use of machinery or technology to assemble components without manual intervention.
Semi-automatic assembly refers to a process that combines both manual and automated techniques.
Composition
Component Alignment and Conveying System: The chaotic components are automatically aligned based on their spatial orientation, which is easily recognizable by the machine. The components are then smoothly conveyed to the subsequent escapement for preparation of the next step, which is usually robotic grabbing.
Grab-Shift-Placement Mechanism: This mechanism is responsible for grabbing the parts that have been positioned by the escapement or vacuumed and moving them to another location, typically the assembly work position.
Assembly Work Organization: This refers to the method used to perform the main assembly task, such as pressing, clamping, screwing, tucking, inserting, welding, riveting, bonding, and welding the workpiece to the previous component.
Testing Mechanism: This mechanism is used to test the assembled parts or the machine’s previous work results, such as checking for missing parts, size inspection, defect detection, function testing, and material inspection.
Workpiece Removal Mechanism: This mechanism is used to sort out the assembled and qualified parts from the machine.
Transmission structure
- Assembly machines can be classified based on the continuity of the flow time of the assembled workpiece in the machine as either gap-movement assembly machines or continuous-motion assembly machines.
- Another way to categorize assembly machines is based on the number of working positions, as either single-station assembly machines or multi-station assembly machines.
- A third classification of assembly machines is based on the drive track of the workpiece, as either circular workbench assembly machines or ring-shaped worktable assembly machines.
Control System
Typically, assembly machines are controlled by a Programmable Logic Controller (PLC).
The PLC receives various signals as inputs and sends instructions to various actuators. The machine also has a variety of sensors and other signal collectors to monitor the performance of each actuator. Based on the information gathered, the PLC issues the next execution instruction.
The machine also has a man-machine interface that displays the machine’s running status and operation record. The operator can use this interface to give instructions to the machine.
Applicability of the automatic assembly machine
With the growth of the economy, many companies have faced labor disputes and difficulties managing their front-line employees. As a result, there has been an increased trend towards the use of automated mechanical assembly.
The application of automatic assembly machines varies depending on the industry. They can be divided into several categories based on their use in different industries, such as electronics and electricals, and hardware.
- Electronics and Electricals:
- Tact switch assembly machine
- Relay automatic assembly machine
- Reset fitness automatic assembly machine
- Transformer automatic assembly machine
- Hardware:
- Caster automatic assembly machine
- Bearing automatic assembly machine
- Toy automatic assembly machine
- Gear automatic assembly machine
- Tooth box automatic assembly machine
Automatic assembly machines are also widely used in the home appliance and automotive industries.
In conclusion, the automatic assembly machine is becoming increasingly popular in the industrialization of factories.
