Light-bulb voltage resistance detection device

Abstract

The invention relates to a light-bulb voltage resistance detection device which comprises a gas-inflation detecting part and a waste light-bulb cleaning part. The gas-inflation detecting part comprises a gas cavity and a light-bulb sealing and fixing mechanism; the gas cavity is provided with a pressure gas introduction opening; the light-bulb sealing and fixing mechanism is arranged below the gas cavity; a stop surface is arranged below the gas cavity; the light-bulb sealing and fixing mechanism comprises a locking colloidal particle, a pressing block and a power moving mechanism; the locking colloidal particle is arranged below the stop surface and provided with a vertical hole in the middle; the pressing block is arranged below the locking colloidal particle and provided with a hole which corresponds to the vertical hole of the locking colloidal particle; and the power moving mechanism is used for driving the pressing block to move up and down. The waste light-bulb cleaning part comprises a vertical guide hole and a mandril, wherein the guide hole is arranged above the gas cavity and communicated with the gas cavity; the mandril is arranged in the guide hole and driven by power. The light-bulb voltage resistance detection device is characterized in that: the lower end surface of the guide hole is provided with the stop surface, the mandril below the stop surface is provided with an externally-raised platform, and a sealing ring is arranged between the externally-raised platform and the stop surface. Compared with the prior art, the light-bulb voltage resistance detection device has the advantages that the sealing component is not easy to damage, the mandril moves smoothly, and the light bulb is not easy to burst due to the pressure gas.

Description

technical field [0001] The invention relates to a detection device for a light bulb. Background technique [0002] The existing bulb withstand voltage detection device, as disclosed in patent 201010558497.0, includes an inflation detection part and a waste bulb cleaning part. The bulb is broken by the pressure gas and ejected from the bulb positioning position. Since the ejector rod is a movable part, its power needs to be provided by the power outside the air guide channel. Therefore, a sealing device needs to be provided between the ejector rod and the air guide channel. The prior art The advanced sealing device adopts a seal between the ejector rod and the ejector rod channel. For this type of sealing device, because the ejector rod needs to move relative to the seal, under high-frequency mutual friction, the seal is easily damaged, resulting in seal failure. Moreover, the seal The parts need to have enough pressure to act on the ejector rod to ensure sufficient sealing ...

[0002] The existing bulb withstand voltage detection device, as disclosed in patent 201010558497.0, includes an inflation detection part and a waste bulb cleaning part. The bulb is broken by the pressure gas and ejected from the bulb positioning position. Since the ejector rod is a movable part, its power needs to be provided by the power outside the air guide channel. Therefore, a sealing device needs to be provided between the ejector rod and the air guide channel. The prior art The advanced sealing device adopts a seal between the ejector rod and the ejector rod channel. For this type of sealing device, because the ejector rod needs to move relative to the seal, under high-frequency mutual friction, the seal is easily damaged, resulting in seal failure. Moreover, the seal The parts need to have enough pressure to act on the ejector rod to ensure sufficient sealing ability, which will inevitably increase the friction of the ejector rod movement, which will easily cause the ejector rod to not move smoothly and affect the cleaning of waste bulbs

In addition, the pressure gas is directly charged into the bulb through the gas guide channel, and the high-speed flowing gas can easily break the bulb
