Abstract

The invention discloses an air tightness detecting device for medical needle heads. The air tightness detecting device comprises a working table and a fixed mold arranged on the working table. A plurality of cavities containing the needle heads are arranged in the fixed mold. An upper moving mold, an upper driving device and a pressure sensor are arranged above the fixed mold. A lower moving mold and a lower driving device are arranged at the bottom of the working table. An input air pipe is arranged in the upper moving mold. A plurality of output air pipes communicated with the input air pipe are arranged on the input air pipe. A plurality of plugs are arranged on the lower moving mold, through holes matched with the plugs and the cavities to be used are arranged on the working table, and the pressure sensor and the input air pipe are connected through air. The lower ends of the needle heads are plugged through the plugs and sealing rings, the air is blown into the needle heads from the upper ends of the needle heads through the input air pipe and the output air pipes, pressure is remained, change of pressure quantity of the input air pipe is detected through the pressure sensor, and a purpose of detecting the air tightness of the medical needle heads is achieved. The operation is simple, convenient and reliable, detecting time is shortened, and cost is reduced.

Description

A kind of medical needle air-tightness detection device
Technical field
The present invention relates to a kind of air-tightness detection device, relate in particular to a kind of medical needle air-tightness detection device, belong to welding technology field.
Background technology
Medical needle comprises the pullover and syringe needle cover for seat of needle holder, and said needle holder is pullover to be integral through Vibration Welding with the syringe needle cover for seat, and their centers are that connect and coaxial through hole; Impermeability for after guaranteeing that needle holder is pullover and welding together with the syringe needle cover for seat guarantees welding quality, needs the impermeability of syringe needle is detected; And the bubble-tight device of present existing detection; Mostly complex structure, and cost is high, and operating of having is also cumbersome; Be inappropriate for the bubble-tight detection of medical needle, therefore need have proposed a kind of special-purpose medical needle air-tightness detection device.
Summary of the invention
Technical matters to above-mentioned existence the objective of the invention is: proposed a kind of simple in structurely, easy to detectly reliably be suitable for a kind of medical needle air-tightness detection device that the medical needle impermeability detects.
Technical solution of the present invention is achieved in that a kind of medical needle air-tightness detection device, comprises worktable, is arranged on the fixed die on the worktable, is provided with the cavity volume of a plurality of splendid attire syringe needles in the said fixed die; Be provided with directly over the said fixed die and move mould, go up drive unit, pressure transducer; Said worktable bottom is provided with and moves down dynamic model, following drive unit; Moving mould on the said upward driving device controls vertically moves; Said driving device controls down moves down dynamic model and vertically moves; Said going up in the mobile mould is provided with gas inlet tube; Said gas inlet tube is provided with a plurality of gas outlet tubes that communicate with it; The said dynamic model that moves down is provided with a plurality of plugs; Said worktable is provided with the through hole that cooperatively interacts and use with plug, cavity volume; Said pressure transducer and gas inlet tube gas connection mutually.
Preferably, said plug top is provided with O-ring seal.
Preferably, said upper and lower drive unit is a telescopic cylinder.
Preferably, the quantity of said cavity volume, gas outlet tube, plug equates.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of medical needle air-tightness detection device of the present invention; Block the lower end of syringe needle through plug, O-ring seal, blow pressurize from the syringe needle upper end to syringe needle is inner through gas inlet tube, gas outlet tube; And then detect the variation of the amount of gas pressure of gas inlet tube through pressure transducer; Detect the bubble-tight purpose of medical needle thereby reach, simple to operate and convenient and reliable, shorten detection time and reduced cost.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
