Description
Technical Field
The invention relates to condom pinhole detection, in particular to a detection device for detecting condom pinholes through water.
Background
At present, the water detector of the conventional condom is generally used for fastening a quantitative water storage cylinder and a sewer pipe communicated with the quantitative water storage cylinder on an equipment bracket, such as a detection device disclosed in Chinese patent CN200810073418.X, an electromagnetic valve is arranged on the sewer pipe to control the water adding time; the test head for hanging the product is fixedly arranged on the fixed plate, and the bidirectional electromagnetic valve is controlled by a computer or a touch screen, so that the test head is driven to lift by the lifting of the fixed plate driven by the cylinder; a loop is formed by an electrode in the test head and an electrolyte tank below the test head during detection, and the voltage difference of two sides of the condom is collected by a data acquisition card to realize the detection of a product; and a common test head is additionally arranged on part of equipment so as to carry out water filling detection when necessary. However, this detection device also has some drawbacks: the existing device needs four cylinders to drive the detection device to move downwards to the electrolyte tank for pinhole detection. Because the air cylinder is driven, when in detection, the air cylinder is used for lifting the detection head, the detection can be started only after the product is completely immersed into the electrolyte, the pressure difference between the inside and the outside of the product is almost zero, and small pinholes in a condom adhesive film are difficult to expand and even can be automatically closed, so that product pinholes (particularly top pinholes) are difficult to detect; the situation that the detection cannot be carried out during the verification test of the top pinhole of the condom frequently occurs in daily use, which can cause the omission of products, and the top pinhole of the condom is the biggest threat to the safety of the products; in order to analyze the pinhole source of a product, a production enterprise needs to judge the position and the state of a pinhole of the product, but a small pinhole is difficult to find by naked eyes, and the purpose of efficiently indicating the position of the pinhole is still not realized by filling the product with water to 300ml for manual inspection; the needle finding hole of the pure rolling absorbent paper is not easy to fix the upper opening of the condom, the rolling skill is not easy to master, and the water absorption of the paper, the rolling speed and the rolling pressure also have certain influence on the detection result, thereby seriously influencing the working efficiency and the detection sensitivity. Moreover, the stability of the air cylinder is difficult to ensure in the operation process, especially when a fixed plate with a detection head is lowered to a detection position, the inertia is large, and each air cylinder is difficult to ensure absolute balance, so that the air cylinder is easy to damage and the fixed plate is easy to damage; simultaneously, the vibration is large, so that the electrode connecting wire of the detection head is easy to break, the detection is influenced, the thin product is easy to fall off, and the detection efficiency is influenced.
In recent years, the inventor and other personnel also invent and use a detector which moves a detection head by an electric sliding table or a screw rod and detects a condom pinhole in the process of realization; however, after the product tank is filled with water, the water surface is often lowered to a position about 10cm below the electrode due to the high elasticity of the condom, so that the condition of the pinhole cannot be really detected in time at the beginning stage, and the detection of the pinhole at the top end of the product is missed.

In order to achieve the purpose, the technical scheme provided by the invention is that the condom pin hole detection device comprises a rack, a water collecting tank arranged on the rack and sewer pipes arranged at intervals under the water collecting tank; a quantitative water storage cylinder and an electromagnetic valve are arranged on the sewer pipe; the device is characterized in that a group of main lifting sliding tables are vertically and oppositely arranged on the racks on the two sides of the sewer pipe, and electrode lifting sliding tables are arranged on the main lifting sliding tables; detection heads capable of being sleeved with condoms are fixedly arranged below the electrode lifting sliding table at intervals; electrodes which can be displaced into the detection head are arranged on the sliding block of the electrode lifting sliding table above the detection head at intervals; the sewer pipe can inject water into the detection head; and an electrolyte tank is arranged below the electrode and the detection head.
The main lifting sliding table comprises lead screws which are vertically arranged on two sides of the rack relatively, a sliding block which can move up and down along the lead screws is sleeved on the lead screws, and the sliding block is fixedly connected with the electrode lifting sliding table.
The lower surfaces of two oppositely arranged electrode lifting sliding tables positioned on two sides of the rack are connected through a fixed plate, mounting through holes are arranged on the fixed plate at intervals, and the detection heads are mounted on the mounting through holes.

Detailed Description
For the above technical solution, a preferred embodiment is described in detail with reference to the drawings, and refer to fig. 1.
A water collecting tank is arranged above the frame 1, a plurality of vertical downcomers 2 are arranged below the water collecting tank at intervals, quantitative water storage barrels 3 are respectively arranged above the downcomers 2, and the quantitative water storage barrels are positioned below the water collecting tank. The lower water pipe below the quantitative water storage cylinder 3 is provided with an electromagnetic valve 4. The downcomer is unsettled and its lower extreme water outlet end is the free end. An overflow pipe 21 is provided at one side of the bottom of the water collecting tank. The downcomers may be provided in one, two or more rows.
A group of vertically arranged main lifting sliding tables 5 are oppositely arranged on the machine frame at two sides of the sewer pipe, and an electrode lifting sliding table 6 is arranged on the main lifting sliding tables. In this embodiment, the main lifting sliding table is driven by a screw rod, and the electrode lifting sliding table is arranged on the screw rod.
The slide blocks on the electrode lifting sliding tables oppositely arranged on two sides of the rack are connected through a cross bar, and electrodes 7 are fixedly arranged on the cross bar at intervals respectively. A fixed plate is fixedly connected below the two opposite electrode lifting sliding tables, hollow detection heads 8 are arranged on the fixed plate at intervals, and the condom can be sleeved on the detection heads. The position of the detection head corresponds to the position of the sewer pipe, so that the electrolyte in the sewer pipe can be directly and completely injected into the condom sleeved on the detection head. The electrode is located the top of detecting the head, and the electrode can be along with the upper and lower displacement of the horizontal pole on the electrode lift slip table, for detecting the head displacement. The electrode can be driven by the sliding block of the electrode lifting sliding table to go deep into the detection head downwards or move upwards to separate from the detection head.
An electrolyte tank 9 is arranged on the frame below the detection head and the electrode, and electrolyte is contained in the electrolyte tank. The electrolyte tank is communicated with the water collecting tank through a water feeding pipe, and the water feeding pipe is communicated with a water pump for providing water feeding power. The lower end of an overflow pipe on the water collecting tank is positioned in the electrolyte tank. The electrode and the electrolyte tank are respectively communicated with the detection circuit. The electromagnetic valve, each lifting sliding table, the detection circuit and the like are respectively connected with the control system, and the actions of the electromagnetic valve, each lifting sliding table, the detection circuit and the like are controlled by the control system.
The action principle and the process of the invention are as follows: and sleeving the condoms to be detected on the detection heads respectively. Then the electrolyte is respectively injected into the quantitative water storage cylinder communicated with the lower water pipe through the water collecting tank by the water feeding pipe, and after the water injection is finished, the redundant electrolyte in the water collecting tank flows back to the electrolyte tank by the overflow pipe. At the moment, the initial position of the condom to be detected is positioned at the lower end of the sewer pipe, and then the electromagnetic valve is opened to inject water in the quantitative water storage cylinder into the condom to be detected sleeved on the detection head. Because the condom is an elastic product, after water injection is finished, the electrode may be separated from the electrolyte level after water injection due to elasticity and gravity, and therefore, after water injection is finished, the electrode lifting sliding table drives the electrode to move downwards by about 10cm, and the electrode is ensured to be immersed into the electrolyte in the condom to be detected. Then the main lifting sliding table is driven by the screw rod to drive the electrode and the condom to be detected on the detection head to gradually and slowly move downwards, and when the lower end of the condom to be detected (namely the seminal vesicle part of the condom) is contacted with electrolyte in the electrolytic bath, the pinhole detection is started. When the pinhole exists, the internal electrolyte and the external electrolyte at the pinhole of the contraceptive to be detected are communicated, so that the detection circuit is communicated, the voltage difference at the pinhole changes, and the pinhole is detected. The pinhole detection is carried out when the pressure difference between the inside and the outside of the condom product is maximum and the expansion of the adhesive film is maximum, so that the sensitivity of the pinhole detection can be obviously improved. Continuous detection is carried out in the whole process that the condom to be detected and the electrode slowly descend, so that the relatively large internal and external pressure difference of the product can be always kept, and the continuous high sensitivity is kept; when a pinhole is detected, an abnormal electric signal is generated (when the voltage exceeds 50mv specified in the GB 7544 rubber condom standard, the pinhole is possible), the displacement when the pinhole is found is recorded through the linkage of a motor or a control system which drives a screw rod to rotate, the position where the pinhole is located is judged by recording the position of the maximum voltage and the voltage difference value of the product in the whole process descending stage, defective products are detected, and meanwhile, favorable information for solving hidden troubles can be provided for production and scientific research units; when the water absorbing paper needs to be rolled for further searching and confirming the pin holes, the time for searching the pin holes can be shortened because the general positions of the pin holes are known in advance. When the detection is finished, the main lifting sliding table drives the electrode and the detection head to ascend to the initial position together.
The invention has the advantages that: the phenomenon that the water in the condom can be separated from the water injection liquid level due to gravity can be overcome by downward displacement of the electrode; and the detection head and the electrode are driven by the screw rod to gradually and slowly downwards and slowly penetrate into the electrolyte tank, so that the pinhole detection can be sequentially carried out from the top (seminal vesicle part) of the condom to the opening at the upper end of the condom, and the general part of the pinhole can be judged. The defect that the general part of the pinhole can not be judged when the condom is immersed into the electrolyte at one time under the driving of the cylinder is avoided, the detection sensitivity and accuracy are improved, and the detection efficiency is improved.
