Automatic assembly machine details

A popular definition of assembly automation

Informally, refers to the products of several parts assembly by fitting, card buckle, threaded connections, adhesive, riveting, welding together get in accordance with a predetermined size precision and function of the finished products (semi-finished products). The assembly, which is implemented by manual processing (contact, finishing, grabbing, moving, placing, exerting, etc.), is strictly speaking and can only be called artificial assembly. Assembly that does not require manual processing (contact, consolidation, grab, move, placement, etc.) components can be called automatic assembly. A semi-automatic assembly between the two.

2. Composition of automatic assembly machine (in order to be discussed in sequence of assembly parts)

1. Component orientation, transmission and escapement system

The disorganized components are arranged automatically in the space orientation automatically processed by the machine, and then smoothly transported to the subsequent escapement mechanism to prepare for the grasping of the robot hand.

2. Grab - shift - placement mechanism

The zero (part) that will be positioned at the point of the escapement will be seized or vacuuming, then moved to another location (usually the assembly position).

3. Assembly work organization

Refers to the organization that is used to complete the work of assembly work, such as pressing the workpiece into, clamping, conching, carping, bonding, welding, riveting, bonding, welding to the last part.

4. Detection mechanism

It is used to detect the work results of the parts or machines assembled in the previous step, such as missing parts detection, dimension detection, defect detection, function detection, and clear material detection.

5. The removal mechanism of the workpiece

An organization used to classify and remove qualified parts from machines.

The most commonly used transmission structure of automatic assembly machine

1) according to the flow time consistency of the assembled workpiece in the machine, there are the gap moving assembly machine and the continuous moving assembly machine.

2) according to the number of working positions in the assembly machine, there are single work station assembler and multi-station assembly machine.

3) according to the transmission trajectory of the workpiece in the assembly machine, there are round working desktop assembler and ring working table mounting machine.

4. Control system of automatic assembly machine

PLC control is usually adopted. The PLC should receive input of various signals and send instructions to the executing agencies. The machine is equipped with various sensors and other signal collectors to monitor the operation of each actuator in the machine, and then the next step of the execution order is issued after judgment. The man-machine interface is used to display the operation of the machine, the running record, and the instruction to the machine by the operator.
