Description

Technical Field

[0001] The invention relates to the technical field of air filter production, in particular to air filter assembly and testing equipment. Background Art

[0002] In the production process of air filters, an automatic air filter assembly machine is used to assemble the filter element, thereby speeding up the assembly and production of air filters. A general automatic air filter assembly machine includes a turntable, an assembly plate, a feeding mechanism, an assembly mechanism, a testing mechanism, and a unloading mechanism. Four assembly plates are fixed on the turntable, and each assembly plate corresponds to a mechanism. During operation, the feeding mechanism places the components on the assembly plate, and then the turntable rotates to rotate the assembly plate to the bottom of the assembly mechanism, and the assembly mechanism assembles the complete filter element components. The turntable then rotates the assembly plate to the bottom of the testing mechanism, and the testing mechanism tests the filter element components to ensure that the filter element components meet production requirements. The turntable then rotates the assembly plate to the unloading mechanism, and the unloading mechanism separates the filter element components from the assembly plate, thereby completing the automatic assembly and testing of the filter element components.

[0003] The detection mechanism in the existing air filter automatic assembly machine generally uses a CCD detection device to detect the filter element components. The CCD detection device is a common industrial visual inspection system that uses a CCD sensor to capture images and analyzes these images through software to determine whether the product meets the quality standards. The CCD sensor takes pictures of the filter element components to detect the size, shape, surface defects and assembly accuracy of the filter element components, ensuring that the quality of the filter element components is within the required range, making it easy to remove defective filter element components.

[0004] As in the prior art, the invention patent with the authorization announcement number CN112763193B discloses a CCD module detection device and a CCD module detection method.

The workbench is provided with a placement groove for placing the CCD module, and the side wall of the placement groove is provided with a through imaging channel, and the lens of the CCD module is arranged toward the imaging channel, and the detection control chip is electrically connected to the test probe and the power supply respectively, and the test probe is used to connect the test interface of the CCD module; the test probe is arranged at the output end of the driving mechanism, and the driving mechanism can drive the test probe to reciprocate along the first direction to connect or disconnect with the test interface; the image board is installed on the base and arranged opposite to the imaging channel, and the image board and the CCD module are separated by a preset distance.

[0005] Although the above technical solution can realize imaging detection of CCD modules and lens dirt detection, the existing CCD detection device still has certain defects when in use: when the existing CCD detection device detects the filter element components on the assembly board, since the assembly board is exposed to the outside world, the external light source will affect the image capture of the CCD sensor, and changes in natural light or lighting intensity in the workshop will also cause inconsistent image brightness, affecting contrast and feature recognition, affecting the detection results, resulting in reduced detection accuracy, and further affecting the quality of the filter element components.

[0037] The air filter assembly and testing equipment of the present invention, when the assembly plate 4 equipped with the assembled filter element components is rotated to the position of the CCD sensor 3, the cover 11 will be opened, and then the movable component will be connected to the assembly plate 4, and then the assembly plate 4 will be pulled to separate the assembly plate 4 from the mounting groove 5, and the assembly plate 4 will enter the isolation box 8 through the sampling port 9, so that the filter element components on the assembly plate 4 are located below the CCD sensor 3, and then the cover 11 is closed, and the CCD sensor 3 will be started, and the filter element components on the assembly plate 4 are photographed through the coaxial light source installed on the CCD sensor 3, and then these images are analyzed by software to determine whether the product meets the quality standards; the isolation box 8 can be used to isolate the external light source, effectively block the interference of external light, and ensure that each detection is carried out under the same lighting environment, thereby improving the clarity and contrast of the image of the filter element components taken by the CCD sensor 3, improving the consistency of the detection results, and thus improving the accuracy of the detection. The isolation box 8 can protect the CCD sensor 3 from dust and the like when the CCD sensor 3 is not in use. In addition, by separating the assembly plate 4 from the turntable 1, the assembly plate 4 is no longer affected by the vibration generated by the turntable 1 and other assembly mechanisms during operation, thereby ensuring a static environment during detection, so that the CCD sensor 3 can capture clearer and more stable images, thereby improving the reliability of the detection results. The shading tape 12 is made of foldable material, such as a black accordion cover. The shading tape 12 can maintain the shading effect of the isolation box 8 without hindering the movement and shooting of the CCD sensor 3. After the detection is completed, the moving component will insert the assembly plate 4 into the installation slot 5, so that the clamping block 6 and the clamping slot 7 are clamped. The clamping block 6 and the clamping slot 7 can be clamped to fix the assembly plate 4, so that the assembly plate 4 will not shake or move during loading, assembly and unloading.

[0038] As a preferred technical solution of the present invention, the moving component includes a slide rod 13, a connecting plate 15, a clamping plate 16, a gear 18 and a motor 19. Two symmetrically arranged slide grooves 14 are provided at the lower part of the isolation box 8, and a slide rod 13 is slidably connected in one of the slide grooves 14. A connecting plate 15 is fixedly connected at one end of the slide rod 13. The connecting plate 15 corresponds to the position of the injection port 9. One end of the connecting plate 15 passes through the injection port 9 and is fixedly connected to the clamping plate 16. A clamping groove 17 corresponding to the position of the clamping plate 16 is provided on the outside of each assembly plate 4. A motor 19 is fixedly connected to the side of the isolation box 8 away from the turntable 1, and a gear 18 is fixedly connected to the output end of the motor 19. A clamping tooth is provided on the side of the slide rod 13 away from the assembly plate 4, and the gear 18 is meshed with the slide rod 13. Two limit assemblies are connected inside each assembly plate 4.

[0039] Specifically, when the assembly plate 4 rotates and changes position, the snap-in plate 16 will be inserted into the slot 17, so that the snap-in plate 16 is connected to the assembly plate 4. After the assembly plate 4 enters the detection position, the motor 19 is started, driving the gear 18 to rotate clockwise. The rotation of the gear 18 will then drive the slide rod 13 to move, so that the connecting plate 15 moves into the isolation box 8, thereby driving the snap-in plate 16 and the assembly plate 4 to enter the isolation box 8 for detection.

[0040] As a preferred technical solution of the present invention, the limiting assembly includes a movable plate 23, an insertion rod 25, a connecting ball 26 and a pressure spring 29. Two symmetrically arranged sliding grooves 22 are provided in the assembly plate 4, and a movable plate 23 is slidably connected in each sliding groove 22. One end of the movable plate 23 is located in the card slot 17 and the end face is an arc surface. Two limiting grooves 24 are provided on the side wall of the other end of the movable plate 23. The limiting grooves 24 are trapezoidal grooves. A plug rod 25 is slidably connected in each limiting groove 24. One end of each plug rod 25 is fixedly connected to a connecting ball 26. Each connecting ball 26 is slidably connected to the inner wall of one of the limiting grooves 24. A slot 27 corresponding to the position of the other end of the plug rod 25 is provided on the inner wall of the mounting groove 5. A placement groove 28 is provided on the bottom surface of the movable plate 23. A pressure spring 29 is fixedly connected in the placement groove 28. The other end of the pressure spring 29 is fixedly connected to the bottom surface of the assembly plate 4. The arc surfaces at the ends of the two movable plates 23 located in the same assembly plate 4 are arranged in the same direction.

[0041] Specifically, when no detection is performed, the insertion rods 25 on both sides of the assembly plate 4 will be inserted into the slots 27. When the clamping plate 16 enters the slot 17, the side walls of the clamping plate 16 will squeeze the arc surface of the movable plate 23, causing the movable plate 23 to slide along the sliding slot 22. At this time, the connecting ball 26 will slide in the limiting slot 24. Since the limiting slot 24 is a trapezoidal slot, the connecting ball 26 will gradually move toward the middle of the assembly plate 4 along the inclined surface of the limiting slot 24, thereby driving the insertion rod 25 to move toward the center of the assembly plate 4, so that the insertion rod 25 is separated from the slot 27. After the clamping plate 16 and the slot 17 are matched, the insertion rods 25 on both sides of the assembly plate 4 will be retracted into the assembly plate 4, and then the motor 19 is started, and the assembly plate 4 can be The assembly plate 4 is pulled into the isolation box 8 for inspection. After the inspection is completed, the assembly plate 4 is inserted into the installation groove 5, and then the clamping plate 16 is separated from the clamping groove 17, the movable plate 23 loses the extrusion, and under the action of the pressure spring 29, the movable plate 23 is reinserted into the clamping groove 17. At this time, the connecting ball 26 will drive the insertion rod 25 to move to both sides until it is reinserted into the slot 27; the mutual cooperation between the insertion rod 25 and the slot 27 is used to further improve the stability of the assembly plate 4 in the installation groove 5, and the centrifugal force generated during the rotation of the turntable 1 is avoided to drive the assembly plate 4 to move, thereby ensuring the stable fixation of the assembly plate 4 on the turntable 1, avoiding shaking or dislocation during the assembly process, and ensuring the safety of the production process and the assembly accuracy of the product.

[0042] As a preferred technical solution of the present invention, the opening and closing assembly includes a torsion spring 30, a connecting rope 31, a connecting rod 32 and a winding wheel 33. A connecting groove 36 is provided at the top of the cover plate 11, and a torsion spring 30 is sleeved on the outer wall of the rotating shaft 10. One end of the torsion spring 30 is fixedly connected to the outer wall of the isolation box 8, and the other end of the torsion spring 30 is fixedly connected to the inner wall of the connecting groove 36. A connecting rope 31 is fixedly connected to one side of the bottom surface of the cover plate 11. A connecting rod 32 is slidably connected in the sliding groove 14 away from the sliding rod 13 in the isolation box 8. A latching tooth is provided on the side wall of one end of the connecting rod 32 close to the connecting plate 15. A driven wheel 38 is rotatably connected to the position of one end of the isolation box 8 close to the connecting plate 15. The lower end of the rotating shaft of the driven wheel 38 is fixedly connected to the winding wheel 33. The other end of the connecting rope 31 passes through the interior of the isolation box 8 and is sleeved on the outer wall of the winding wheel 33, and the latching tooth matches the position of the driven wheel 38.

[0043] Specifically, if Fig.14As shown, a hole for accommodating the connecting rope 31 is opened in the isolation box 8. After the end of the assembly plate 4 is pulled into the isolation box 8, it will continue to move for a distance so that the filter element component is aligned with the CCD sensor 3. At this time, the latching teeth on the connecting rod 32 will drive the driven wheel 38 to rotate, and then drive the winding wheel 33 to rotate. The winding wheel 33 will reel in the connecting rope 31. After the connecting rope 31 is reeled in, it will pull the cover plate 11, so that the cover plate 11 blocks the sample inlet 9, thereby achieving the sealing of the interior of the isolation box 8 and preventing external light sources from entering from the sample inlet 9. After the detection is completed Afterwards, the winding wheel 33 is reversed with the cooperation of the driven wheel 38 and the connecting rod 32, and the connecting rope 31 is loosened. At this time, the torsion spring 30 will open the cover 11, so that the cover 11 is opened to about 90 degrees, thereby opening the sample inlet 9, facilitating the assembly plate 4 to be removed from the isolation box 8; through this arrangement, the automatic opening and closing of the cover 11 is achieved without the need for an additional power source, which simplifies the equipment structure, reduces energy consumption, ensures the closure of the detection environment, effectively avoids the influence of external light sources on the CCD sensor 3, and improves the accuracy and reliability of the detection results.

[0045] Specifically, the square light ring 34 can provide a uniform and stable lighting environment for the filter element component during the detection process, ensuring that the filter element component receives consistent light intensity and angle during shooting, avoiding image quality problems caused by local overbrightness or overdarkness. By surrounding the light from all sides, the square light ring 34 can effectively reduce shadows and reflections on the surface of the filter element component, which helps to detect surface defects and measure dimensions. The uniform lighting can ensure that the image information captured by the CCD sensor 3 is more real and reliable, which helps to improve the contrast and clarity of the image and improve the detection accuracy.

[0047] Specifically, by utilizing the mutual cooperation between the fixed magnetic block 20 and the connecting magnetic block 21, the accurate connection between the snap-in plate 16 and the snap-in slot 17 can be ensured, and the movement of the assembly plate 4 and the snap-in plate 16 can be avoided, thereby avoiding the risk of the assembly plate 4 and the mounting slot 5, the sample inlet 9, etc. not being able to accurately cooperate, thereby improving the operating stability of the entire detection system.

[0048] As a preferred technical solution of the present invention, a fixed magnet 35 is fixedly connected to one side of the isolation box 8 . The fixed magnet 35 is located below the injection port 9 , and the fixed magnet 35 corresponds to the position of the cover plate 11 .

[0049] Specifically, after the cover 11 is combined with the isolation box 8, the cover 11 is made of ferromagnetic material, and the fixed magnet 35 will firmly adsorb the cover 11 on the isolation box 8, thereby improving the airtightness of the cover 11 to the injection port 9. After the detection is completed, as the assembly plate 4 moves, the assembly plate 4 will squeeze the cover 11. Under the squeezing of the assembly plate 4, the cover 11 will separate from the fixed magnet 35. At this time, under the action of the torsion spring 30, the cover 11 can be fully opened.
