Automatic assembly line, automatic assembly line

The automatic assembly machine includes automatic loading and unloading device, positioning fixture, assembly execution structure, sensor and control system. The positioning fixture is designed according to the shape and size of the specific workpiece. The assembly actuator is specially designed with the necessary process, Rail mechanism, linear bearings, ball screw mechanism and other components. Usually in this type of automated assembly machine to complete the process are: automatic bonding, parts of the insert, the semiconductor surface mount, all kinds of screw nut connection, riveting, adjustment, testing, labeling, packaging and so on. In addition to the assembly process, in this automated assembly line can also be used part of the simple machining process.

       Automatic assembly line is a special product-oriented layout. The assembly line refers to a continuous production line connected by some material handling equipment. Assembly line is a very important technology, it can be said that any with a variety of parts and mass production of the final product to some extent are used assembly line production. Therefore, the layout of the assembly line by the assembly line equipment, products, personnel, logistics and production methods and other factors.

        It is usually assumed that the beat of the assembly line is constant and that the processing time of all workstations is substantially equal. Different types of assembly, there are very different, mainly reflected in:

        1. Assemble the material handling equipment (belt or conveyor, crane) on the production line;

        2. Type of production line layout (U type, linear type, branch type);

        3. Beat control form (maneuver, man);

        4. Assemble varieties (single or multiple products);

        5. Assemble the production line workstation characteristics (workers can sit, stand, follow the assembly line or move with the assembly line, etc.);

        6. Assemble the length of the production line (several or more workers).

Automatic assembly line is an effective combination of man and machine, the most fully embodies the flexibility of the device, it will transport system, accompanying fixture and online plane, testing equipment, organic combination to meet the requirements of multi-product assembly. The transmission mode of the assembly line is synchronous transmission / (mandatory) can also be non-synchronous transmission / (flexible), according to the configuration of the choice, to achieve manual or semi-automatic assembly. The assembly line is indispensable in the mass production of the enterprise.

Automated assembly line balance

        The balance of the assembly line is to make the balance between the personnel or the machine as much as possible so that the output of the assembly line can meet the required level. The assembly line balance problem is implicated in the planning of the facility. The balance of the assembly line directly affects the productivity of the manufacturing system.

   The assembly line balance problem is a matter of implication with facility planning. The total amount of work done by a workstation is consistent with the total number of basic work units assigned to the workstation. The problem of assembly line balancing is to assign all the basic work units to the various workstations so that each workstation is in a busy state in the beat (ie, the interval between the two adjacent products through the end of the assembly line), the maximum amount of operation is done, Of the unspecified time (idle time) at least.

   The balance of the assembly line is a very important issue in the design and management of the production line, since the balance of the assembly line directly affects the productivity of the manufacturing system. In the past few decades, people have done a lot of research on the balance of the assembly line, has received a lot of theoretical results.
