And a method of operating a stage of a detector, comprising the steps of:

s010, before the object detection of the object stage, the air extractor 120 is started to blow air to the adsorption through hole 602 through the guide pipe 701, when the external control IC detects that the measurement values of one or more air pressure sensors are not in the preset range, the alarm is given and the position of the current air pressure sensor is pointed out, otherwise, the external control IC outputs a normal signal of equipment; the function is to detect whether the gas circuit is normal or not and can adsorb an object to be detected;

s011, when the external control IC gives an alarm, cleaning the guide pipe 701 and the thimble 601 corresponding to the air pressure sensor giving the alarm by the external control IC, and returning to the step S010 after the cleaning is finished;

s020, placing the object to be detected above the thimble 601 and pressing downwards until the object to be detected does not shake obviously;

s021, after placing the object to be tested, before starting the air extractor 120, the external control IC checks whether the ambient humidity is in a threshold range through a humidity sensor on the air extractor 120, if so, the next step is carried out, otherwise, when starting the air extractor 120, the air inlet or the air outlet of the air extractor 120 is arranged at the starting position of the drying device;

s022, in the process that the object to be detected leaves from the placement state, the external control IC detects the ambient humidity in real time through a humidity sensor on the air extracting device 120, whether the drying device needs to be closed or started is judged, and the drying device is powered off when the air extracting device 120 is powered off;

s030, starting the air extraction device 120, extracting air on the adsorption through hole 602 through the guide pipe 701, and adsorbing the object to be detected;

s031, the air pressure sensor reports real-time data to the external control IC for at least 3 seconds, and the external control IC determines which thimble 601 does not need to be adsorbed or strongly adsorbed by the mathematical model before and after the data reporting is finished, so as to close the corresponding conduit 701 or increase the air pressure;

and S040, after the object to be detected is detected, the air exhaust device 120 stops working on the ejector pins 601, the reset plate 301 installed on the telescopic device 110 is pushed upwards by applying work to the telescopic device 110, and after all the ejector pins 601 move upwards to reset, the air exhaust device 120 applies work to the telescopic device 110 to enable the reset plate 301 to move downwards to reset.

It should be noted that the mathematical model provided on the external control IC is a conventional pneumatic common technology, and will not be described in detail herein. The external control IC is generally a computer or a PLC plus computer. In the case that the number of the thimble 601 is larger, the more the guide tube 701 is arranged in the airtight chamber 102, the more the guide tube 701 is wound and bent, and thus, not only the arrangement and fixation work of the guide tube 701 needs to be done, but also whether the guide tube 701 is bent or not needs to be detected through the step S010 before use. Furthermore, when the apparatus is in the erection mode, i.e. by combining a plurality of said erection tanks 101 together, the general method of operation used is the same as described above, but each erection tank may be individually provided with suction means or driven by a powerful general suction means.

In summary, the assembled box 101, the sealing plate 201, the movable cylinder 501, the ejector pins 60 and other components are connected together through a smart structure, so that the object to be tested is stably and firmly supported, the irregular object is prevented from shaking or scratching the surface of the object to be tested during testing, and meanwhile, under the condition that the air exhaust device is arranged externally, the other components can be made of non-metal materials, so that the interference on the inspection is avoided; the long service life of the equipment can be ensured and the power consumption can be reduced by matching with a corresponding operation method, so that the energy is saved and the environment is protected; the structure is stable and compact. The practical value of the invention is greatly improved.

The above-described examples merely represent one or more embodiments of the present invention, which are described in greater detail and detail, but are not to be construed as limiting the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the spirit of the invention, which falls within the scope of the invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
