A sensor automatic calibration device

Abstract

The invention discloses an automatic sensor calibration device, which includes a work area, a buffer area and a transmission structure. The work area includes a calibration box, and the calibration box is used for calibrating the devices to be calibrated in the buffer area. It includes a buffer box, and the buffer box is used to buffer the temperature and humidity of the device to be calibrated in it; the calibration box includes a hollow and airtight box body, a heating device and a humidifying device arranged in the box body, and a At least one first opening and a sealing door on the box body; the conveying structure is used for conveying the device to be calibrated thereon to a corresponding position. The sensor automatic calibration device of the present invention automatically transmits the device to be calibrated to the calibration environment by means of automatic transmission, which avoids some manual operations and ensures the consistency to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an automatic calibration device for sensors. Background technique [0002] At present, there is no unified standard for the calibration box, and the calibration methods are different according to the product type. For example, sensors in the humidity industry also need to go through a series of calibration processes before leaving the factory to make the output data accurate. In the existing Most of the time, some control devices are used on the equipment to make the calibration environment meet the calibration requirements, but this process requires a certain amount of time and the stability of the equipment to achieve reliable calibration, and this type of sensor generally needs to collect multiple data. Therefore, the existing equipment can only perform sequential calibration by adjusting different environments, which consumes a lot of time, especially when readjusting the env...

Problems solved by technology

[0002] At present, there is no uniform standard for the calibration box, and the calibration methods are different according to the product type. For example, the humidity industry sensor also needs to go through a series of calibration processes before leaving the factory to make the output data accurate. In the existing Many times on the equipment, some control devices are used to make the calibration environment meet the calibration requirements, but this process requires a certain amount of time and equipment stability to achieve reliable calibration, and this type of sensor generally needs to collect multiple data. Therefore, the existing equipment can only be calibrated sequentially by adjusting different environments, which consumes a lot of time, especially when readjusting the environmental values, it takes longer to reach a stable state

[0003] In the existing technology, it is difficult to carry out large-scale production, because there are some uncontrollable problems in the whole process. If there are multiple calibration environments in the calibration process, the equipment needs to be switched continuously, but in The stability of the calibration environment will appear during the switching process, so it takes more time to achieve stability after switching the environment. In addition, some sensors still need to be placed on another device during the calibration process. During this transfer process It also needs to be protected, otherwise it will also affect the accuracy of the data during the transfer process

Therefore, there are still many unstable factors on the existing equipment.
