The full-automatic method of manufacturing technology of connector
Technical field
The present invention relates to a kind of processes of automated production equipment, more specifically to a kind of industrial products
The process of automated production equipment.
Background technology
Standardization and interchangeability of the Automated assembly based on parts in 19th century machinery manufacturing industry, start to be used for small-sized force
The production of device and clock and watch is then applied to auto industry again.In 20th century, Ford Motor Company of the U.S. initially sets up using transport
Operation break-down is carried out professional assembly manipulation in each process, makes shorten about assembly period by the mobile automobile assembly line of band
90%, reduce production cost.The appearance and development of interchangeability manufacture and mobile assembly line are large quantities of mass productions using automatic
Change opens road, and it is simple automatic then to occur hopper-type self-feeder and screw, automatic tightening machine for nut etc. successively
Makeup is set.In the 1960s, with digital control technology rapid development, occur the degree of automation it is higher and have compared with
The numerical assembling machine of big adaptability, it is possible to using Automated assembly in multi items medium-duty.It is nineteen eighty-two, Japanese
Individual factories are using digital control industrial robot come the AC servomotor of automatic assembling plurality of specifications.
The Automated assembly of machine refers to the automation of machine assembler's skill process.Automatic assembly system can be divided into two kinds
Type:One is based on the rigid automatic assembly system for producing assembly in enormous quantities, mainly by Assembling Special Equipment and special tool
Skill equipment is formed;The second is flexible assembly system FAS (the flexible assembly based on flexible manufacturing system
System), mainly it is made of assembly center (assembling center) and the people that puts together machines (assembly robot).By
The flexible manufacturing and computer integrated manufacturing system development produced in whole world manufacturing industry forward direction multi items, small lot, so flexible dress
Match system is the developing direction of Automated assembly.
In general, the assembling work of machine is more complicated than other processing operations, to ensure the smooth implementation of Automated assembly, need
Have the following conditions.
(1) structure and assembly technology for realizing the engineering goods of automatic assembling should keep certain stability and advance.
(2) automatic assembly equipment or the transfer lines of assembling used should ensure that the assembling quality of machine.
(3) assembly technology used by should be ensured that Automated assembly easy to implement.
(4) engineering goods to be assembled and its parts should have good automatic assembling processability of product structure.
The assembly line and ancillary equipment of mating part mechanization realize local automation's assembly and full-automatic assembly,
The clamping device with tool and fixture accordingly is must be provided on automated assembly machine, to ensure assembled part mutual alignment
Claimed accuracy, realize the possibility of unit assembling and pincers worker operation, such as load onto, remove, back-out one be screwed into, compresses one unclamp,
Indentation, riveting, polishing and other necessary operations.Automatic assembling machine can be divided into rotary type and straight because of workpiece mode of movement difference
Two class of type according to the complicated and simple difference of process, and can be divided into single-station, multiplexing bit architecture.Rotary type automatic assembling machine is usually used in assembling
Number of parts is few, appearance and size is small, assembly beat is short or assembling work requires high assembly occasion.As for Norm part size compared with
Greatly, assembly station is more, detects that process is more or the multiplexing of hand assembled and automatic assembling hybrid manipulation especially in assembling process
Sequence is assembled, then to select straight moving type automatic assembling machine to be advisable.
Assembly automation is to improve production efficiency, reduces cost, ensure product quality, especially mitigate or replace it is special
Under the conditions of manual assembly labour.Realize that assembly automation is the important symbol of Automation of Manufacturing Process or factory automation,
It is the important content that system analysis engineering is implemented in mechanical manufacturing field.
