[0003] In the prior art, when a filter element is manufactured, it is necessary to test the pore size of the filter element raw material. The pore size test of the filter element raw material ensures that the filter element has appropriate filtering performance and meets specific application requirements. In actual application, the surface of the filter element raw material needs to be kept flat during the test so that the test data is accurate in subsequent processes. However, during the pore size test of the filter element raw material, if the material appears uneven or uneven when placed on the testing instrument, this may have a negative impact on the accuracy of the test results.

A controller, fixedly mounted on a side wall of the base; Among them, when the flattening component is in operation, it will apply airflow to the surface of the sample, which helps to remove gas residues in the sample, and the force of the airflow can promote the flattening of wrinkles on the sample surface, thereby helping to reduce wrinkles or unevenness on the sample surface. After the flattening component is completed, the operator drives the sample clamp to clamp the sample through the switch, and then cooperates with the test cavity to test the aperture of the sample, which helps to reduce the occurrence of inaccurate test results due to the uneven surface of the sample.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a flattening component.

By adjusting the angle of the blow head to blow in an oblique direction, it helps to flatten the wrinkles on the sample. Moreover, because one end of the sample is already stable, such blowing ensures the stability of the sample during operation and avoids sample displacement caused by wind force.

By extending the return time and controlling the working speed of the air pump in this process to reduce the blowing rate of the blow head, it is beneficial to prevent the blow head from causing the sample to wrinkle.

DETAILED DESCRIPTION

[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0031] like Figures 2 to 11 The automobile filter element detection mechanism shown in the figure comprises a base 1, a test cavity 2 is arranged on the base 1, a sample holder 3 is fixedly mounted on the base 1, a sample holder 4 is connected to the sample holder 3, a switch 5 is fixedly connected to the side wall of the base 1, and further comprises: Two slots 6 are respectively provided on two side walls of the sample holder 4; Two slides 7 are slidably connected to the inside of the two slots 6 respectively; A driving assembly, disposed on the outer wall of the sample holder 4, for driving one of the slides 7 to move; The flattening component is arranged between the two slides 7. After the sample is placed at the designated position, the flattening component is used to perform a slight flattening treatment on the sample to prevent the unevenness of the sample from affecting the test result; A controller 8 is fixedly mounted on a side wall of the base 1; In specific implementation, after the sample to be tested is prepared and placed in the designated position, the controller 8 first controls the flattening component to blow and limit the contact portion between the sample and the test cavity 2. This processing method helps to enhance the tightness between the sample and the test cavity 2, and reduces direct contact with the sample through the directional effect of the airflow, thereby reducing the risk of sample damage caused by contact. Then the controller 8 controls the drive component to start, and the drive component drives the slide 7 connected to it to slide inside the slot 6, and the slide 7 drives the flattening component to move. When the flattening component is in operation, it will apply airflow to the surface of the sample, which helps to remove gas residues in the sample, and the force of the airflow can promote the flattening of wrinkles on the sample surface, thereby helping to reduce wrinkles or unevenness on the sample surface. After the flattening component is completed, the operator drives the sample clamp 4 to clamp the sample through the switch 5, and then cooperates with the test cavity 2 to test the aperture of the sample, thereby helping to reduce the occurrence of inaccurate test results due to the uneven surface of the sample.

[0032] As a technical optimization solution of the present invention: the flattening processing component includes: Two slide bars 9 are rotatably connected to opposite sides of the two slide frames 7; The air cylinder 10 is arranged at one end of the two slide bars 9 close to each other; Two gears 11 are fixedly connected to the outer walls of the two slide bars 9 respectively; Two torsion springs 12 are fixedly installed between the gear 11 and the slide 7 at corresponding positions. The air pump 13 is fixedly mounted on the side wall of the air cylinder 10; The blowing head 14 is fixedly connected to the side wall of the air cylinder 10; In a specific implementation, the controller 8 controls the air pump 13 to start, and the air pump 13 blows air into the interior of the air cylinder 10 and blows it out through the blowing head 14. The airflow blown out by the blowing head 14 acts on the surface of the sample, which is beneficial to limit the sample. Then the slide 7 drives the slide bar 9 to move, the slide bar 9 drives the air cylinder 10 to move, and the air cylinder 10 drives the blowing head 14 to move, thereby blowing the surface of the sample on the moving path during the movement, so as to help ensure that the sample fits more closely with the cavity during the test through the assistance of the airflow, while avoiding potential damage to the sample caused by direct touch.

[0033] It should be noted that the slide bar 9 is connected to the wind tube 10, and the slide bar 9 can both rotate and slide on the wind tube 10. The interior of the slot 6 is divided into two inclined sections and one flat section. In fact, the movement trajectory of the slide 7 when sliding inside the slot 6 is to gradually move outward in the first inclined section, that is, the slide 7 pulls the slide bar 9 to slide outward inside the wind tube 10, then reaches the flat section and remains unchanged, and finally gradually moves inward in the second inclined section, that is, the slide 7 pulls the slide bar 9 to slide inward inside the wind tube 10 to return to its original position.

[0034] As a technical optimization solution of the present invention: it also includes: The rack 16 is fixedly mounted on the sample holder 4; A semi-annular groove 17 is provided on the outer wall of the wind tube 10; The electromagnet 18 is fixedly mounted inside the semi-annular groove 17; A connecting frame 19 is fixedly mounted on the side wall of the gear 11; The sliding rod 20 is fixedly mounted on the side wall of the connecting frame 19 and is slidably connected to the interior of the semi-annular groove 17; In the above example, the sample is straightened by blowing air to prevent the surface of the sample from being uneven, which may affect the test results. However, relying solely on vertical wind force may not effectively eliminate wrinkles or unevenness on the sample surface. Therefore, the adhesive can be placed on the test cavity 2 in advance, because the blowing direction of the blowing head 14 is vertically downward in the initial state, the airflow acting on the sample by the blowing head 14 can be used to make the sample fit with the test cavity 2, and as the sliding rod 9 moves, the gear 11 will be driven to move, and the gear 11 will drive itself to rotate after contacting with the rack 16, and the gear 11 will drive the sliding rod 9 to rotate, and the sliding rod 9 will drive the air cylinder 10 to rotate, and the air cylinder 10 will drive the blowing head 14 to rotate a specified angle, and the specified angle is pre-set by the operator, and the gear 11 will also drive the connecting frame 19 to rotate during the rotation process, and the connecting frame 19 will drive the sliding rod 20 to rotate, and the sliding rod 20 will rotate. The rod 20 is made of a material that the electromagnet 18 can adsorb, such as iron. When the sliding rod 20 slides inside the semi-annular groove 17 and contacts the electromagnet 18, the electromagnet 18 will strongly adsorb the sliding rod 20, thereby maintaining the inclination angle of the blowing head 14, and then the blowing head 14 blows the sample at an inclined blowing angle, and the blowing angle is toward the non-fixed end. By adjusting the angle of the blowing head 14, it is blown in an oblique direction, which helps to flatten the wrinkles on the sample. Moreover, because one end of the sample is already stable, such blowing ensures the stability of the sample during operation and avoids sample displacement caused by wind force.

[0035] As a technical optimization solution of the present invention: it also includes: Two pull rods 21 are respectively fixedly mounted on the ends of the two slide rods 9 close to each other; Two telescopic members 22 are respectively fixedly mounted on the ends of the two pull rods 21 that are close to each other; A tension spring 29, which is fixedly installed inside the telescopic member 22 and sleeved on the outer wall of the pull rod 21; In specific implementation, when the slide 7 pulls the slide bar 9 to slide outward inside the air tube 10, the slide bar 9 drives the pull rod 21 to slide outward, and the pull rod 21 drives the telescopic part 22 to contract, thereby releasing the blockage of the blowing head 14, so that the blowing range of the blowing head 14 gradually expands as it moves toward the middle of the sample, and the blowing coverage area expands accordingly as it moves toward the center of the sample to adapt to the size of the sample, thereby adapting to the area of ​​the sample. On the one hand, the blowing range of the blowing head 14 is concentrated in the initial state, which helps the sample and the test cavity 2 to quickly achieve a tight fit. On the other hand, during the blowing process, as the area of ​​the sample that needs to be blown increases and decreases during the movement, it automatically adjusts, which helps the blowing head 14 to automatically adjust its wind coverage range to ensure that the wind is always concentrated on the sample. Through this concentrated and adjustable wind action, it helps to more effectively flatten the sample surface and improve the quality and efficiency of sample processing.

[0036] It should be noted that the tension spring 29 applies tension to the telescopic member 22 so that the telescopic member 22 returns to its original position, and the telescopic member 22 can be telescopically folded.

[0037] As a technical optimization solution of the present invention: it also includes: A plurality of intercepting rods 23 are fixedly mounted on the side wall of the wind tube 10; A plurality of interception cylinders 24, each of which is rotatably connected to the interception rods 23 at corresponding positions; In specific implementation, after the detection is completed, the controller 8 controls the electromagnet 18 to cut off the power and lose its magnetism. The sliding rod 20 that loses the limit quickly returns to its original position under the action of the torsion spring 12. In order to prevent the sample from wrinkling during the return of the blow head 14, an intercepting cylinder 24 is set for interception. The intercepting cylinder 24 and the intercepting rod 23 have some damping effect during the installation process, which will hinder the return speed of the blow head 14. By extending the return time and controlling the working speed of the air pump 13 in this process, the blowing rate of the blow head 14 can be reduced, which is beneficial to prevent the blow head 14 from causing the sample to wrinkle.

[0038] As a technical optimization solution of the present invention: the driving assembly includes a mounting plate 25, the mounting plate 25 is fixedly mounted on the side wall of the sample clamp 4, a motor 26 is fixedly mounted on the mounting plate 25, a threaded rod 27 is fixedly connected to the output shaft end of the motor 26, a threaded seat 28 is threadedly connected to the outer wall of the threaded rod 27, the threaded seat 28 is slidably connected to the sample clamp 4, a yielding rod 15 is fixedly mounted on the side wall of the threaded seat 28, and the yielding rod 15 is fixedly connected to one of the slides 7; In a specific implementation, the controller 8 controls the motor 26 to start, the motor 26 drives the threaded rod 27 to rotate, the threaded rod 27 drives the threaded seat 28 to move, the threaded seat 28 drives the yield rod 15 to move, and the yield rod 15 drives the slide 7 to move; When the carriage 7 returns outward or inward, a relative movement occurs between the relief rod 15 and the threaded seat 28 .

[0039] As a technical optimization solution of the present invention: it also includes: The timing unit is used to time the working time of the motor 26.

[0040] like Figure 1 A detection system for a vehicle filter element detection mechanism is shown, and the detection system comprises the following steps: The controller 8 obtains the test sample placement completion information; The controller 8 generates first control information and second control information according to the test sample placement completion information; The controller 8 sends the first control information to the blowing head 14 to control the blowing head 14 to start blowing; The controller 8 sends the second control information to the motor 26 to control the motor 26 to start working.

[0041] As a technical optimization solution of the present invention: it also includes: The controller 8 obtains the timing completion information of the timing unit; The controller 8 generates third control information according to the timing completion information; The controller 8 sends the third control information to the electromagnet 18 to control the electromagnet 18 to be energized and generate magnetism.

[0042] As a technical optimization solution of the present invention: it also includes: The controller 8 continuously obtains the flatness information of the test sample; The blowing size of the blowing head 14 is controlled according to the flatness information of the test sample.

[0043] Working principle of the present invention: After the sample to be tested is prepared and placed in the designated position, the controller 8 first controls the flattening component to blow and limit the contact portion between the sample and the test cavity 2. This processing method helps to enhance the tightness between the sample and the test cavity 2, and reduces direct contact with the sample through the directional effect of the airflow, thereby reducing the risk of sample damage caused by contact. Then the controller 8 controls the drive component to start, and the drive component drives the slide 7 connected to it to slide inside the slot 6, and the slide 7 drives the flattening component to move. When the flattening component is in operation, it will apply airflow to the surface of the sample, which helps to remove gas residues in the sample, and the force of the airflow can promote the flattening of wrinkles on the sample surface, thereby helping to reduce wrinkles or unevenness on the sample surface. After the flattening component is completed, the operator drives the sample clamp 4 to clamp the sample through the switch 5, and then cooperates with the test cavity 2 to test the aperture of the sample, thereby helping to reduce the occurrence of inaccurate test results due to the uneven surface of the sample.
