Method.
Background technique
Injection molding mechanical arm is mainly used for cooperating production, crawl and the stacking etc. of injection molding machine product.Its control system passes through
Signal interaction is carried out with injection molding machine, control manipulator electrical component is issued an instruction to, realizes the safe operation of manipulator.To real
When existing injection molding machine injection molding production, it is opened automatic part picking, operating staff labor intensity is reduced, product is placed on setting regions automatically.
It can choose single perhaps stacking of putting and put or be placed on product automatically the function etc. that assembly line flows upwardly to packing area.
Kinetic control system chief component includes the critical components such as teaching machine, controller, I O board, servo-driver, servo motor.
Currently, the safety operation in order to guarantee injection molding mechanical arm, the safety during especially molding and be opened, use
A variety of safety precautions, such as the outer safety signal of major-minor arm origin signal, type, allow to mold signal, mould area safety signal etc.
Wired logic.But because operating environment is complicated, situation is chaotic, and wiring is more and logic is complicated, be easy to appear wiring fault and
Illusive situation, leads to work safety accident.
Also, the wiring of above-mentioned safety measure is more and loads, and a large amount of time is needed to be connect before installing and using work
Line operation, control installation operation and safety inspection operation, waste the more time.
Summary of the invention
In view of the above technical problems existing in the prior art, an object of the present invention is to provide a kind of injection molding mechanical arm peace
The circuit of full guard.The circuit reduction mode of connection, reduces installation steps and installation control, while can prevent from being molded again
Safety problem caused by manipulator and injection molding machine wiring are lack of standardization.
The second object of the present invention is to provide a kind of injection molding mechanical arm method for security protection, and this method is based on above-mentioned injection molding
Manipulator safety protective circuit is realized.
The technical solution adopted by the present invention is as described below.
The present invention provides a kind of injection molding mechanical arm safety protective circuit, and the safety protective circuit includes being cascaded
Injection molding mechanical arm circuit part and injection molding machine circuit part.The injection molding mechanical arm circuit part includes that principal arm rises origin letter
Number, auxiliary rise the outer safety verification signal of origin signal and Z axis type, and principal arm rises origin signal and auxiliary rises origin signal
It is in parallel with safety verification signal outside Z axis type after series connection.The injection molding machine circuit part includes allowing to mold signal and mould area peace
Full signal, and allow to mold signal and the parallel connection of mould area safety signal.
Further, the principal arm, which rises origin signal and auxiliary rising origin signal, is realized by photoelectricity origin switch
's.
Further, the outer safety verification signal of the Z axis type is realized by photoelectric sensor switch.
The present invention also provides a kind of injection molding mechanical arm method for security protection, which comprises
The principal arm of injection machine on hand is risen and is pacified after origin signal is connected with auxiliary rising origin signal with outside Z axis type
Full confirmation signal is in parallel；
Signal and the parallel connection of mould area safety signal will be allowed to mold on injection molding machine；
Above-mentioned two circuit part is connected.
Injection molding mechanical arm circuit part: injection molding mechanical arm has principal arm and auxiliary, is mounted with photoelectricity respectively on two mechanical arms
Origin switch is for determining whether mechanical arm returns origin.When the physical signal of the two origin switch pass to injection molding machine when
It waits, illustrates two mechanical arms while reaching preset physics origin, manipulator is not in the die cavity of injection molding machine at this time, place
In safe condition, injection molding machine can be molded.Photoelectric sensor switch is installed outside injection molding mechanical arm Z axis type, works as photoelectric sensor switch
When sensing that manipulator auxiliary is close, illustrate not reaching even if one or all in two mechanical arms preset
The position of physics origin, two mechanical arms will not be molded to injection molding machine and die sinking impacts, and injection molding machine can mold.
Injection molding machine circuit part: injection molding machine exists and allows to mold signal and mould area safety signal, when the two signals simultaneously
There are when, illustrate it is in a safe condition in injection molding machine die cavity, injection molding machine can mold complete moulding production.If gone out
The missing of any one existing signal then illustrates that there is insecurity factors in injection molding machine die cavity.If injection molding machine molding at this time
Words, will be damaged injection molding machine or moulding the case where, generate production accident, this does not allow.
It can be seen that according to above-mentioned injection molding mechanical arm safety protective circuit when the principal arm of injection molding mechanical arm rises origin signal
When all passing to injection molding machine with auxiliary rising origin signal, injection molding machine allows molding signal and mould area safety signal could be defeated
Out.When safety verification signal passes to injection molding machine outside the Z axis type of injection molding mechanical arm, injection molding machine allows to mold signal and mould area
Safety signal can also export.If the principal arm of injection molding mechanical arm rises origin signal, auxiliary rises and pacifies outside origin signal and Z axis type
When full confirmation signal all passes to injection molding machine, injection molding machine allows molding signal and mould area safety signal that can also export.
Allow to mold signal Y1 and mould area on three signaling points and injection molding machine of the present invention by providing injection molding mechanical arm
It is series-parallel that safety signal Y2 does hardware signal, reinforces safety protection function.It is a pipe protection is provided in software function exception more,
Improve the safety and reliability that manipulator is applied in injection molding machine.
The invention has the following beneficial effects: 1, safety caused by wiring error when can effectively prevent manipulator adjustment and installation
Problem；2, save installation steps, set-up time, reduce installation control, specification installation process, improve arm-and-hand system reliability and
Safety.
