Description

Technical Field

[0001] The utility model belongs to the technical field of gas sensor aging, in particular to an aging device for gas sensor production. Background Art

[0002] A gas sensor is a converter that converts the volume fraction of a gas into a corresponding electrical signal. The detection head conditions the gas sample through the gas sensor, usually including filtering out impurities and interfering gases, drying or refrigerating the instrument display part. After the gas sensor is produced, it needs to be aging tested, which requires the use of an aging device.

[0003] The aging device places the gas sensor inside the aging device and then ages the gas sensor through the circulation of gas. The current aging device can only perform individual aging tests on the gas sensor when testing the gas sensor, and cannot achieve the aging efficiency under different gas concentrations, which leads to inaccurate test data and reduces the practicality of the entire device. For this reason, we propose an aging device for gas sensor production. Utility Model Content

[0004] In order to solve the problem that the current aging device can only perform individual aging detection on the gas sensor when detecting the gas sensor, and cannot achieve the aging efficiency under different concentrations of gas, thereby resulting in inaccurate detection data and reducing the practicality of the entire device, the utility model provides the following technical solutions: An aging device for gas sensor production, comprising a box body, the surface of the box body is provided with two opening and closing doors, the side of the box body is fixedly connected to a support plate, the top of the support plate is provided with a gas storage tank, the top of the gas storage tank is connected to an output pipe, the other end of the output pipe is connected to a connecting pipe, the side of the connecting pipe is connected to a transfer pipe, a sealing gasket is provided between the connecting pipe and the box body, the inner cavity of the box body is provided with a plurality of placement plates, the top of the placement plates is provided with a placement groove, and the bottom of the inner cavity of the box body is provided with an adjustment mechanism capable of adjusting the height of the placement plates.

[0005] Preferably, the adjustment mechanism includes a servo motor, a rotating shaft, a first gear, a chain, a threaded rod and a second gear. The servo motor is installed at the bottom of the inner cavity of the casing. The rotating shaft is fixedly connected to the output end at the top of the servo motor through a coupling. The first gear is fixedly sleeved on the circumferential surface of the rotating shaft. The threaded rod is rotatably inserted in the casing. The second gear is fixedly sleeved on the circumferential surface of the threaded rod. The two ends of the chain are respectively sleeved on the second gears, and the middle part of the chain is sleeved on the first gear.

[0006] Preferably, a threaded hole is provided on the top of the placement plate, and the threaded rod is connected to the threaded hole by threads.

[0007] Preferably, there are two groups of the adjustment mechanisms, which are respectively located at the front and rear sides of the bottom of the box.

[0008] Preferably, there are a plurality of placement plates, and the plurality of placement plates are distributed in the inner cavity of the box at equal intervals.

[0009] Preferably, the number of the transfer tubes is several, the number of the transfer tubes is the same as the number of the placement plates, and each transfer tube is arranged corresponding to the placement plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By placing the gas sensor in the placement slot on the placement plate, then closing the switch door, and then opening the gas storage tank, the gas inside the gas storage tank is transported to the connecting pipe through the output pipe, and then to the transfer pipe through the connecting pipe. The transfer pipe can then transport the gas into the box. Since the connecting pipe is long, the gas density at the bottom of the box is lower, and the gas density at the top of the box is higher. The concentration at different heights in each layer inside the box is also different. The servo motor is started through the wire connection, and the servo motor drives the shaft to rotate, the shaft drives the first gear to rotate, and the first gear drives the chain roller through the tooth pattern. The chain drives the second gear to rotate through the tooth pattern, and the second gear drives the threaded rod to rotate. The threaded rod drives the placement plate to slide up and down through the threaded connection with the threaded hole, so as to adjust the height of the placement plate, thereby realizing aging detection of gas sensors at different heights. Multiple placement plates can perform aging detection on multiple gas sensors at the same time, which realizes that the current aging device can only perform separate aging detection on the gas sensor when detecting the gas sensor, and cannot achieve aging efficiency under different concentrations of gas, which leads to inaccurate detection data and reduces the practicality of the entire device.
