[0002] A flow sensor is a sensor that can measure the velocity, direction and size of airflow. According to different principles and designs, airflow sensors can be divided into hot wire, hot film, ultrasonic, differential pressure and other types. Among them, hot wire airflow sensors are more commonly used. Its principle is to calculate the velocity of airflow by measuring the temperature change of the hot wire. Hot wire airflow sensors can be divided into two design circuits: constant current type and constant temperature type. Among them, the constant temperature type is more commonly used.

DETAILED DESCRIPTION

[0018] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0019] Example 1

[0020] A recycling airflow sensor detection device, such as Figure 1-Figure 4 As shown, it includes an installation frame 1, an airflow sensor body 2, an annular support plate 101, a pin 3, a motor 4, a support rod 401, a clamping plate 5, a second guide rod 502, a second spring 503, a support block 504, a detection machine 6, a connecting plate 601, a fan 602, a control panel 7, a positive and negative contactor 8 and a wire 801. The motor 4 is installed in the installation frame 1, and the annular support plate 101 is installed on the installation frame 1. The output shaft of the motor 4 is connected to the support rod 401 through a coupling. A plurality of support blocks 504 are installed on the side of the support rod 401. The number of the support blocks 504 is 4, which can be increased or decreased as needed. The second guide rods 502 are symmetrically installed on the support blocks 504, and two second springs 503 are sleeved on the outer side of one of the second guide rods 502. The second guide rods 502 are all slidably connected with a clamping plate 5, and the airflow sensor body 2 is movably clamped in the clamping plate 5. The pins 3 are symmetrically installed at the bottom of the airflow sensor body 2. A detection machine 6 is arranged on the right side of the installation frame 1. A connecting plate 601 is installed on the top of the detection machine 6. A fan 602 is arranged in the connecting plate 601. A control panel 7 is installed on the side of the detection machine 6. The fan 602 is connected to the control panel 7. A positive and negative contactor 8 is installed on the side of the detection machine 6. The pins 3 movably contact the positive and negative contactors 8. The wires 801 pass through the side of the detection machine 6, and the wires 801 are respectively connected to the positive and negative contactors 8. The fan 602 is located above the positive and negative contactors 8. A connecting rod is installed on the bottom side of the detection machine 6, and the end of the connecting rod away from the detection machine 6 is installed on the right side of the installation frame 1.

[0021] Push the clamping plates 5 to both sides, put the airflow sensor body 2 into the two clamping plates 5, and the motor 4 starts to work, driving the support rod 401 to rotate. When the support rod 401 rotates with the airflow sensor body 2 to the detection machine 6, the pin 3 contacts the positive and negative contactors 8 respectively, and the fan 602 starts to blow air to the airflow sensor body 2. The airflow sensor body 2 transmits the sensed wind data to the pin 3, and the pin 3 transmits it to the control panel 7 through the positive and negative contactors 8 to display the data. If the data is within a reasonable range, pull the clamping plate 5 outward, and the airflow sensor body falls into the rework collection box, otherwise, it falls into the destruction box.

[0022] Example 2

[0023] On the basis of Example 1, Figure 2As shown, it also includes a cylinder 402, a first guide rod 403, a first spring 404 and an extrusion block 501. A plurality of cylinders 402 are installed on the top of the support rod 401, and the pistons of the cylinders 402 are connected to the extrusion blocks 501. The clamping plate 5 is extruded and matched with the extrusion blocks 501. A plurality of first guide rods 403 are installed on the top of the support rod 401, and the first springs 404 are sleeved on the outside of the first guide rods 403. The extrusion blocks 501 are slidably connected to the first guide rods 403.

[0024] The airflow sensor bodies 2 are clamped on the clamping plates 5 one by one. After the detection is completed, the detected airflow sensor bodies 2 are rotated to one side. According to the detection data, the cylinder 402 is controlled to work. If rework is required, when it reaches the top of the collection frame, the cylinder 402 pushes the extrusion block 501 downward to move, and the extrusion block 501 squeezes the clamping plate 5 downward. The clamping plate 5 moves to both sides, and the airflow sensor body 2 loses its clamping and falls down into the collection frame. On the contrary, it is squeezed above the destruction frame, and the airflow sensor body 2 falls into the destruction frame, which has the effect of automatic classification.

[0025] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
