Abstract
The invention relates to a high-voltage wet type electric examination method for producing condoms, which comprises the following steps: sleeving the condom on a metal mould; immerging the mould and the condom into a conducting liquid, and using a high-voltage power supply to detect the voltage between two electrodes; and detecting current which passes through the condom by an amperemeter, wherein if the current is heavier than a decision value, the condom is judged to be an unqualified product, and if the current is lower than the decision value, the condom is judged to be a good product, and the like. The step (2) also comprises the following steps: only immerging the head parts of the mould and the condom into the conducting liquid; applying high-voltage electric shock which is higher than the detection voltage of between 70 and 100V between the two electrodes, and then powering off; immerging the parts below the margins of the mould and the condom into the conducting liquid; and applying detection voltage by the high-voltage power supply and a medium-voltage power supply respectively between the two electrodes for two times of detection, and the like. The method not only can detect pinholes or leakage in the middle part of the condom, but also can particularly and effectively detect the pinholes or the leakage of the crucial head part, and the residual rate and the fallout ratio are reduced by 60 to 80 percent so as to greatly improve the quality of outgoing products and the reliability of contraception and pathogen transmission prevention.
Description
Technical field
The invention belongs to the condom manufacture technical field, more particularly relate to the innovation of high-voltage wet type electric examination method for producing condom.
Background technology
Electric-examination is one of critical process of condom manufacture.It can differentiate out and remembers sorting then the substandard product that hole or seepage are arranged, in the specification product sorting of free of pinholes or ne-leakage to qualified case, in substandard product sorting to defective case.Specification product change subsequent processing by the standard pick test over to after qualified.
The method of traditional wet electric-examination in the past is to be sleeved on sheath to be detected on the metal die one by one; Metal die is dipped in the conductive liquid together with (except the portion of limit) below the portion of sheath limit; Metal die and conductive liquid respectively are an electrode of electric-examination; Between two electrodes, apply 36V or littler safe voltage with power supply, detect electric current with galvanometer then through sheath.If detected electric current, explains that sheath has pin hole or seepage greater than decision content, be judged to unacceptable product and reject; If detected electric current less than decision content, is explained sheath free of pinholes or seepage, be judged to good product and get into next procedure.Apply 36V or following low voltage between two electrodes of this electric-examination method, detection sensitivity and resolution are lower, and the loss and the false drop rate of sheath are bigger, have guaranteed not the quality and the conformance with standard requirement of the product that dispatches from the factory.
The applicant's patent No. is that the Chinese patent that ZL200720028636.2, name are called " condom manufacture electricity consumption checking device " discloses a kind of new electric-examination device.It is brought up to the voltage that applies between two electrodes between the 220V-1500V, and sensitivity and resolution are high, the loss and the false drop rate of sheath are lower.
But in above-mentioned tradition and improved electric-examination device, the head of sheath and metal die are fitted does not have expansion, the middle part of sheath since the somewhat larger in diameter of metal die in the diameter of sheath and by the expansion attenuation.Therefore, the pin hole or the seepage at middle part are prone to be detected during electric-examination, and the pin hole of crucial head or seepage is difficult for being detected that is easy omission, thereby quality defects.The head of sheath comprises that seminal vesicle is very crucial position in fact, and its pin hole or seepage often make seminal fluid spill and cause contraceptive failure.Therefore, the pin hole of crucial head region or seepage are prone to by omission, are unsolved key issue in the condom manufacture all the time.
Summary of the invention
The object of the invention just is to overcome above-mentioned shortcoming and defect, and a kind of improved high-voltage wet type electric examination method for producing condom is provided.It not only can detect the pin hole or the seepage at sheath middle part, especially can effectively detect the pin hole or the seepage of crucial head, reduces loss and false drop rate greatly, improve greatly the product that dispatches from the factory quality and contraception, prevent the reliability of pathogen transmission.
In order to achieve the above object, the present invention includes following steps:
(1) be sleeved on sheath to be checked on the metal die one by one;
(2) metal die is immersed in the conductive liquid together with the sheath that puts one by one, respectively be an electrode of electric-examination to metal die and conductive liquid, between two electrodes, apply moment detection voltage through the contact with high-voltage power supply;
(3) apply when detecting voltage, detect electric current through sheath with galvanometer, if detected electric current greater than decision content, this sheath is judged to unacceptable product and rejects; If detected electric current is less than decision content, this sheath is judged to good product and gets into next procedure.
Above-mentioned steps (2) also comprises step by step following:
1. only the head of metal die together with the sheath that puts immersed in the conductive liquid;
2. between two electrodes, apply the high voltage 0.2-0.3 that is higher than detection voltage 70V-100V with high-voltage power supply and shock by electricity outage then second;
3. again with metal die together with immersing below the limit portion of the sheath that puts in the conductive liquid;
4. between two electrodes, apply respectively with high-voltage power supply and middle voltage source and detect voltage 0.2-0.3 second, to accomplish twice detection.
The present invention is immersed the head of metal die together with the sheath that puts in the conductive liquid earlier, carries out the 0.2-0.3 electric shock in second to be higher than the high voltage that detects voltage 70V-100V, even also the head of sheath bears more high-tension impact.If the head quality of sheath is fine, can not make it produce pin hole, micropore, seepage or other defective even be higher than the high voltage impact that detects voltage 70V-100V yet.If the head of sheath is second-rate, is higher than the high voltage impact that detects voltage 70V-100V and can makes it produce pin hole, micropore, seepage or other defective, just can it be rejected in the detection of step below.Thereby greatly reduce loss and false drop rate, improved greatly the product that dispatches from the factory quality and contraception, prevent the reliability of pathogen transmission.
Detect voltage between 700V-1000V, should confirm according to the kind of sheath.The electric current decision content should be confirmed according to the kind of sheath equally.
The present invention adopts the detection mode of the little electric current of high voltage.High voltage can guarantee the high sensitivity and the high resolving power that detect, reduces the loss and the false drop rate of sheath.And the personal safety of little electric current can guarantee to detect the time is respond well.
The current-limiting protection resistance of also connecting in the high-voltage power supply.When in case electric current surpasses limit value with regard to auto-cutout, the personal safety in the time of can further guaranteeing to detect.
Task of the present invention comes to this and accomplishes.
The present invention not only can detect the pin hole or the seepage at sheath middle part; Especially can effectively detect the pin hole or the seepage of crucial head; Loss and false drop rate have reduced 60%-80%, improved greatly the product that dispatches from the factory quality and contraception, prevent the reliability of pathogen transmission.It can be widely used in the production of sheath.
