A kind of vacuum pressure sensor pick-up unit
Technical field
Whether the utility model relates to a kind of vacuum pressure sensor pick-up unit, can put in place for detection of raw material, belongs to electric automatization field.
Background technology
In the automated production process of automatic stamping and stretching, in mould, lack material and just there will be mould pneumatics, produce the problem of pausing.And the product of having suppressed in mould does not remove, and virgin material is put into mould and will be caused double sheet compacting, directly mold damage.Because die space is limited, in mould, increase and misplace device and sometimes cannot realize.Therefore, guarantee that mechanical arm material grasping is stable in the automated productions such as punching stretch, it is very important ensureing not lack material, not falling material, do not leak material.In process of producing product, because mechanical arm speed is fast, action is many, adopt artificial visually examine's the long-time detection of mode just to there will be personnel to reflect not in time and misoperation, produce tired erroneous judgement and fail to judge for a long time, cause occurring the misoperation of automation equipment, mould pneumatics, the problems such as mould double sheet compacting.So just cannot ensure the automated production of fast and stable, increase production cost, reduce production efficiency.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide the pick-up unit that whether a kind of effective detection raw material puts in place, whether product removes in time, simple in structure, but safety and stability is high, has also improved production efficiency when having reduced human input.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of vacuum pressure sensor pick-up unit, comprise: vacuum generator, alarm and control system, described vacuum generator is provided with a sensor for detection of self vacuum pressure, the vacuum pressure detecting is transferred to control system by described sensor, controls system triggers alarm and make equipment out of service in the time that vacuum pressure is less than the force value of setting.
Aforementioned vacuum generator comprises: for the vacuum cup of adsorption production, the sucker guide rod of connection vacuum cup.
Aforementioned sucker guide rod is hollow structure, and described pressure transducer is arranged on sucker guide rod and with the vacuum area in sucker guide rod and is communicated with.
In addition, pick-up unit of the present utility model also comprises a restorer, manually press restorer after restorer send reset signal to control system to sound all clear.
In actual industrial production, in most of punching stretch automated productions, all adopt vacuum cup to grab by starting material, vacuum is grabbed by mode and is widely used in all trades and professions in addition.The material grasping mode of vacuum cup is exactly to make sucker and between material grasping, formed a relative vacuum state, realizes and captures material.If can not be formed the vacuum tightness of a safety between material grasping and vacuum cup, just mean that sucker does not grab material.We utilize such a relevance parameter exactly, realize the detection that lacks material.In the time that control system perception vacuum pressure is less than the pressure of setting value, will send signal and stop the operation of production equipment, and send alarm signal, remind production patrol officer to detect and lack material, do respective handling by producing patrol officer.
Usefulness of the present utility model is: vacuum pressure sensor pick-up unit of the present utility model, by the acting in conjunction of vacuum generator, alarm and control system, detect effectively, reliably and on handgrip, whether have material, thereby accurately judge whether raw material is added and whether product is removed, greatly liberate yield-power, reduce human cost, improved production efficiency, promoted automatization level.
Brief description of the drawings
Fig. 1 is the structural representation of a specific embodiment of vacuum pressure sensor pick-up unit of the present utility model.
The implication of Reference numeral in figure: 1, vacuum cup, 2, sucker guide rod, 3, sensor, 4, product, 5, control system, 6, restorer, 7, alarm.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1, a kind of vacuum pressure sensor pick-up unit of the present utility model, comprise: vacuum generator, alarm 7 and control system 5, on vacuum generator, be provided with a sensor 3 for detection of self vacuum pressure, then the vacuum pressure detecting is transferred to control system 5 by sensor 3, control system 5 trigger alarm devices 7 make equipment out of service in the time that vacuum pressure is less than the force value of setting, patrol officer does respective handling after receiving alerting signal.This detection mode is effectively reliable and timely, has ensured that the safety of production is carried out.
Particularly, vacuum generator comprises: for the vacuum cup 1 of adsorption production 4, the sucker guide rod 2 of connection vacuum cup 1.As shown in Figure 1, product 4 is adsorbed on vacuum cup 1, and sucker guide rod 2 is hollow structure, has formed vacuum area in hollow structure, and pressure transducer 3 is communicated with this vacuum area, detects vacuum pressure and pressure value is transferred to control system 5 and differentiate.
In addition, pick-up unit of the present utility model also comprises a restorer 6, produces after patrol officer finishes dealing with, and manually presses the rear restorer 6 of restorer 6 and sends reset signal to control system 5 and just sounded all clear, and production is proceeded.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
