Condom pinhole detection device

Abstract

A condom pinhole detection device comprises a rack, a water collecting tank arranged on the rack and downcomers arranged below the water collecting tank at intervals. Quantitative water storage barrels and electromagnetic valves are arranged on the downcomers; a group of main lifting sliding tables are vertically and oppositely arranged on the rack on the two sides of the downcomers, and electrodelifting 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 tables at intervals; electrodes are arranged on the sliding blocks of the electrode lifting sliding tables above the detection head at intervals; the electrodes can move downwards into the detection head; the downcomers can inject water into the detection head; and an electrolyte tank is arranged below the electrodes and the detection head. The condom pinhole detection device has the advantages that pinhole detection can be sequentially carried out from the top (seminal vesicle part) of the condom to the opening in the upper end of the condom upwards, and the general part of the pinhole can be judged. The detection sensitivity and accuracy are improved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to condom pinhole detection, in particular to a detection device for detecting condom pinholes through water. Background technique [0002] At present, the conventional condom water detector generally fastens the quantitative water storage cylinder and the sewer pipe connected with the quantitative water storage cylinder on the equipment support, such as the detection device disclosed in Chinese patent CN200810073418. The valve controls the timing of adding water; the test head of the suspended product is fixed on the fixed plate, and the two-way solenoid valve is controlled by a computer or a touch screen to realize that the cylinder drives the lifting of the fixed plate to drive the lifting of the test head; through the electrodes in the test head and the lower The electrolyte tank forms a loop during detection, and the voltage difference on both sides of the condom is collected through the data acquisition card to realize produ...

Problems solved by technology

However, there are still some defects in this detection device: each group of existing devices needs four cylinders to drive the detection device down to the electrolyte pool for pinhole detection

Due to the cylinder drive, when testing, use the cylinder to lift the detection head, and the detection can only be started after the product is completely immersed in the electrolyte. At this time, the pressure difference between the inside and outside of the product is almost zero, and the small pinholes in the condom film are difficult to swell. Open or even close automatically, which makes it difficult to detect pinholes in the product (especially the pinhole at the top); in daily use, it often happens that the pinhole at the top of the condom cannot be detected during the verification test, which may lead to missed detection of the product , and the pinhole on the top of the condom is the biggest threat to product safety; in order to analyze the source of the pinhole in the product, the manufacturer needs to judge the position and state of the pinhole in the product, and the small pinhole is difficult to find with the naked eye, and the product is filled with water Up to 300ml, the manual inspection has not yet achieved the purpose of efficiently indicating the pinhole position; simply rolling absorbent paper to find the pinhole is not easy to fix the top of the condom, and the rolling skills are not easy to master, and the water absorption of the paper and the speed and pressure of rolling are also difficult. Have a certain impact on the detection results, seriously affect the work efficiency and detection sensitivity

Moreover, it is difficult to ensure the stability of the cylinder during operation, especially when the fixed plate with the detection head is lowered to the detection position, the inertia is large, and it is difficult to ensure absolute balance of each cylinder, so the cylinder is easy to be damaged. It is also easy to cause damage to the fixing plate; at the same time, due to the large vibration, it is easy to cause the electrode connection wire of the detection head to break, thereby affecting the detection, and it is easy to cause the thin product to fall off, affecting the detection efficiency

[0003] In recent years, I and other personnel have also invented and used a detector that uses an electric slide or a screw to move the detection head, and detects the pinhole of the condom during the process; , causing the water surface to drop to a position about 10cm below the electrode, resulting in the fact that the pinhole cannot be detected in time at the beginning stage, resulting in the omission of the pinhole detection at the top of the inspection product
