DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5The sensor automatic characteristic detection device comprises a table body 1, a base 3 is fixedly arranged on the top of the table body 1, a detachable load-bearing plate 4 is installed on the top of the base 3, and a gas hood 2 that moves upward and downward is sleeved on the outer side of the base 3 above the table body 1. A gas pipe 22 is arranged on one side of the gas hood 2, and the gas pipe 22 extends into the interior of the gas hood 2 and communicates with the gas supply channel 23. A plurality of pressing plates 7 are fixedly arranged inside the gas hood 2, and the pressing plates 7 move synchronously with the gas hood 2.

[0021] The gas delivery pipe 22 is a corrugated pipe, through which the gas to be detected can be input into the gas delivery hood 2, and the gas is discharged into the gas delivery hood 2 through the gas supply port on the gas supply channel 23, so that the gas can be detected by the sensor to be detected 6 on the bearing plate 4, thereby realizing the characteristic detection of the sensor to be detected 6. A sealing member is laid at the bottom of the gas delivery hood 2 to ensure the airtightness of the gas delivery hood 2.

[0022] Among them, a plurality of bottom holes 31 are provided on the base 3, and a metal probe 32 is fixedly arranged in each bottom hole 31. The metal probe 32 and the sensor to be detected 6 are adapted to each other, and the sensor to be detected 6 can be powered by the metal probe 32, and the detection result of the sensor to be detected 6 is displayed by an external computer host. This is a prior art, and its specific structure and working method are all prior art currently disclosed on the market, which are not common knowledge known to those skilled in the art, and are not the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0023] A plurality of installation cavities 42 are vertically penetrated through the load-bearing plate 4 , and the installation cavities 42 are all aligned with the bottom holes 31 , and the installation cavities 42 are all adapted to the sensors 6 to be detected.

[0024] Among them, multiple positioning columns 5 are fixed and vertically arranged upward at the corners of the base 3, and positioning cavities are adapted to the corresponding positioning columns 5 on the load-bearing plate 4. Through the arrangement of the positioning columns 5, the load-bearing plate 4 can be positioned and assembled above the base 3.

[0025] Among them, N-pole magnetic blocks 41 are fixedly arranged on both sides of the top of the load-bearing plate 4, and S-pole magnetic blocks 71 that attract each other are adapted and fixedly arranged on both sides of the pressure plate 7 corresponding to the N-pole magnetic blocks 41. Through the mutual adsorption between the N-pole magnetic blocks 41 and the S-pole magnetic blocks 71, the load-bearing plate 4 can be adsorbed under the pressure plate 7.

[0026] Among them, a plurality of guide columns 21 are fixedly arranged vertically upward on the top of the table body 1, and the gas supply hood 2 is movable on the guide columns 21. Through the arrangement of the guide columns 21, the gas supply hood 2 can be kept stable during the upward and downward movement.

[0027] In this embodiment, when the user needs to perform a characteristic test on the sensor 6 to be detected, the user only needs to transfer the sensor 6 to be detected to the mounting cavity 42 on the load-bearing plate 4. Then, the gas hood 2 is pulled upward, and then the load-bearing plate 4 is adsorbed under the pressing plate 7 through the mutual adsorption between the N-pole magnetic block 41 and the S-pole magnetic block 71. Then, the gas hood 2 is pressed downward, and in the process of the gas hood 2 moving downward, the pressing plate 7 drives the load-bearing plate 4 to move downward. When the gas hood 2 moves to the bottom, the load-bearing plate 4 moves to the top of the base 3. At this time, the sensors 6 to be detected in the load-bearing plate 4 are automatically in contact with the metal probe 32.

[0028] At this time, the user only needs to input the detection gas into the gas supply hood 2 through the gas supply pipe 22, and then wait for the sensor to be detected 6 to be detected. In this way, the characteristic detection of the sensor to be detected 6 can be realized, and during the assembly process of the sensor to be detected 6, it is not easy to loosen and displace, so that the detection accuracy is improved. It is also worth noting that the pressure plate 7 is located on both sides of the top of the sensor to be detected 6, which will not affect the detection effect of the sensor to be detected 6. And a silicone pad is set at the bottom of the pressure plate 7, which will not damage the sensor to be detected 6.

[0029] The load-bearing plate 4 is mounted on the bottom of the pressing plate 7 so that it moves downward through the pressing plate 7, which can effectively prevent the sensor 6 to be detected on the load-bearing plate 4 from being lifted up by the metal probe 32 due to inaccurate positioning during the contact with the metal probe 32. The setting of the pressing plate 7 can fix and position the sensor 6 to be detected so that it can stably contact the metal probe 32.

[0030] In the utility model, the characteristic detection of the sensor to be detected 6 can be realized by the arrangement of the air supply hood 2 and the base 3, and the loosening and displacement of the sensor to be detected during the assembly process can be prevented by the arrangement of the load-bearing plate 4 and the pressure plate 7, thereby enhancing the characteristic detection effect of the sensor to be detected 6.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
