Description

Technical Field

[0001] This invention relates to the field of filter manufacturing technology, and in particular to a device and method for detecting missing sealing rings. Background Technology

[0002] Filters are an indispensable device in pipelines transporting media, typically installed at the inlet end of pressure reducing valves, pressure relief valves, level control valves, and other equipment. With a filter cartridge containing a filter screen of a specific size, impurities are blocked. When cleaning is required, simply remove the detachable filter cartridge, clean it, and reinstall it. Therefore, use and maintenance are extremely convenient.

[0003] During the filter manufacturing process, sealing rings need to be installed at the filter ports to prevent leakage during later installation and use. However, currently, sealing rings are often missing during filter assembly. Therefore, the assembled filters are inspected. However, existing inspection methods are not suitable for assembly line filter production and still rely on manual handheld inspection devices, resulting in low inspection efficiency and hindering factory production. Therefore, we propose a sealing ring missing detection device and its detection method to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this application is to provide a sealing ring missing detection device and detection method to solve the problem mentioned in the background art that the existing detection methods are not suitable for the production line production of filters, and still rely on manual handheld detection devices, resulting in low detection efficiency and being detrimental to factory production.

[0005] To achieve the above objectives, this application provides the following technical solution: a sealing ring missing detection device, including a workbench, a support tube fixedly installed on the top of the workbench, and a support platform rotatably connected to the top of the support tube, a stepper motor fixedly installed on the bottom of the workbench, the output shaft of the stepper motor passing through the support tube and fixedly connected to the bottom of the support platform, a clamping assembly installed on the top of the support platform, and multiple filters clamped at equal intervals on the clamping assembly;

[0006] A slide rail is fixedly installed on the top of the workbench, and a support plate is slidably connected to the slide rail. A transmission component is connected to the right side of the support plate. The transmission component is connected to the top of the workbench and the bottom of the support plate respectively. A test component is installed on the top left side of the support plate, and the right side of the test component extends to the right side of the support plate.

[0007] With the above structure, after clamping multiple filters simultaneously using the clamping assembly, the stepper motor can be started to drive the support platform to rotate. At this time, multiple filters can move intermittently. When the support platform moves, under the transmission cooperation of the transmission assembly, the support plate can be driven to move laterally and reciprocate, thereby driving the test assembly to move. This allows the test assembly to dock with multiple filters individually, realizing the power-on test of the filters. This makes it easy to test whether each filter is equipped with a sealing ring, and multiple filters can be tested simultaneously. Therefore, batch testing can be achieved when producing filters in the factory, improving work efficiency.

[0008] Preferably, the clamping assembly includes a U-shaped frame, a pressure plate, multiple positioning components, and a braking component;

[0009] The U-shaped frame is fixedly installed at the top center of the support platform, and the pressure plate is slidably sleeved on the U-shaped frame. The positioning components are connected to the bottom of the pressure plate and the top of the support platform respectively, and the positioning components are clamped to the corresponding filters. The braking components are connected to the top of the pressure plate on the inner wall of the U-shaped frame respectively.

[0010] Furthermore, by driving the braking component, the pressure plate can be moved downwards, thereby positioning and clamping the filter under the action of the positioning component.

[0011] Preferably, the positioning component includes an upper clamping plate and a lower clamping plate;

[0012] The upper clamping plate is fixedly installed at the bottom of the pressure plate, and the lower clamping plate is fixedly installed at the top of the support platform. The filter is clamped to the corresponding upper and lower clamping plates respectively.

[0013] Furthermore, with the cooperation of the upper and lower clamping plates, the filter can be positioned and clamped.

[0014] Preferably, the braking component includes a rotating rod, a pressure rod, a positioning ring, a locking rod, and a braking spring;

[0015] The rotating rod is rotatably connected to the top inner wall of the left side of the U-shaped frame, and the top end of the pressure rod is rotatably connected to the rotating rod. The bottom end of the pressure rod is slidably connected to the top of the pressure plate. The locking rod passes through the top inner wall of the right side of the U-shaped frame and is slidably connected to the top inner wall of the right side of the U-shaped frame. The positioning ring is fixedly installed on the top right side of the rotating rod, and the locking rod passes through the positioning ring and is locked with the positioning ring.

[0016] The brake spring is sleeved on the clamp rod and is located inside the U-shaped frame. The left and right ends of the brake spring are fixedly connected to the clamp rod and the right inner wall of the U-shaped frame, respectively.

[0017] Furthermore, by rotating the rotating rod, the pressure rod can be driven to move in an arc shape to the lower right, which can drive the pressure plate to move downward. When clamping the filter, the clamping rod can be made to engage with the positioning ring. Then, under the action of the braking spring, the clamping rod can be driven to move to the left to form a clamping relationship with the positioning ring, so that the pressure plate can be limited by rotating the rod and the pressure rod.

[0018] Preferably, the U-shaped frame is fitted with two tension springs located above the pressure plate, and the top and bottom ends of the tension springs are fixedly connected to the top of the U-shaped frame and the pressure plate, respectively.

[0019] Furthermore, the tension spring can provide an upward pulling force to the pressure plate, which can conveniently and elastically limit the pressure plate and prevent it from moving downward at will.

[0020] Preferably, the transmission assembly includes a rotating shaft, a transmission roller, a transmission ring, a stop block, a gear component, a telescopic component, and a transmission rod;

[0021] The rotating shaft is rotatably connected to the top left side of the worktable, and the transmission roller is fixedly sleeved on the rotating shaft. The transmission ring is sleeved on the transmission roller, and a spiral annular groove is opened on the transmission roller. The stop block is fixedly installed on the inner side wall of the transmission ring, and one side of the stop block extends into the annular groove and engages with the inner wall of the annular groove.

[0022] The gear component is installed at the bottom of the support platform, and the top of the rotating shaft is connected to the gear component;

[0023] The telescopic component is installed on the left side of the transmission ring, and the left end of the telescopic component is connected to the right side of the support plate. The bottom end of the transmission rod is rotatably connected to the top left side of the worktable, and the top end of the transmission rod is connected to the telescopic component.

[0024] Furthermore, under the transmission action of the gear component, the rotating shaft can be driven to rotate. At this time, under the transmission cooperation of the annular groove and the stop block, the transmission ring can be driven to perform longitudinal reciprocating motion. Under the transmission action of the transmission rod, the telescopic component can be made to operate, thereby enabling the test component to perform lateral reciprocating motion through the support plate.

[0025] Preferably, the telescopic component includes a support frame, a movable cover, a limiting rod, and a compression spring;

[0026] The support frame is fixedly installed on the left side of the transmission ring, and the limiting rod is fixedly installed on the right inner wall of the support frame. The left end of the limiting rod extends into the movable cover and is slidably connected to the inner wall of the movable cover. The left and right ends of the compression spring are fixedly connected to the left inner wall of the movable cover and the left end of the limiting rod, respectively. The top end of the transmission rod extends into the support frame and is rotatably connected to the bottom right side of the movable cover. The left side of the movable cover is slidably connected to the bottom right side of the support plate.

[0027] Furthermore, as the support frame reciprocates longitudinally with the transmission ring, it can drive the moving cover to reciprocate laterally under the transmission of the transmission rod, thereby realizing the transmission of the support plate.

[0028] Preferably, the gear component includes a gear ring and a gear;

[0029] The gear ring is fixedly installed at the bottom of the support platform, and the gear is fixedly installed at the top of the rotating shaft, with the gear meshing with the gear ring.

[0030] Furthermore, the meshing transmission of the ring gear and the gear can drive the rotating shaft to rotate when the support platform rotates.

[0031] Preferably, the test assembly includes a fixing cover, a positive terminal rod, a negative terminal rod, LED beads, and a battery;

[0032] The fixed cover is fixedly installed on the top left side of the support plate, and both the positive and negative terminal rods penetrate the support plate and are fixedly connected to it. The battery is fixedly installed inside the fixed cover. The left end of the positive terminal rod is electrically connected to the positive terminal of the battery, and the left end of the negative terminal rod is electrically connected to the negative terminal of the battery. The LED is fixedly installed on the left side of the fixed cover, and the LED's power-connecting pins extend into the fixed cover and are electrically connected to the negative terminal rod.

[0033] Furthermore, the filter can be tested using the positive and negative terminals, thereby determining whether a sealing ring is installed inside the filter.

[0034] This invention also proposes a detection method for a sealing ring missing detection device, comprising the following steps:

[0035] S1: Place multiple filters on their respective lower clamps;

[0036] S2: Pushing the rotating rod can move the pressure plate downwards, and the upper clamp can be used to position and clamp the filter;

[0037] S3: After the filter is clamped, the lever can be released. The brake spring, which is under force, can push the lever through the positioning ring to position the pressure plate and keep the filter in a fixed position and clamped.

[0038] S4: Starting the stepper motor can drive multiple filters to move, and at the same time drive the test components to operate, thereby enabling the individual testing of multiple filters.

[0039] In summary, the technical effects and advantages of this invention are as follows:

[0040] 1. In this invention, after placing the filter to be tested on the corresponding lower clamping plate, the rotating rod can be pushed to rotate to the right, thereby driving the pressure rod to move in an arc shape to the lower right. At this time, the pressure plate can be pushed to move downward. When the pressure plate moves downward, multiple upper clamping plates can be driven to move downward. When the rotating rod rotates to a horizontal state, the filter can be positioned and clamped under the action of the upper clamping plates.

[0041] 2. In this invention, after the filter is positioned and clamped, the stepper motor can be started to drive the support platform to rotate. At this time, multiple filters can rotate intermittently at a certain angle, which can facilitate the position adjustment of multiple filters, thereby enabling multiple filters to be docked with the test component.

[0042] 3. In this invention, when the support platform rotates, the rotating shaft can rotate under the meshing transmission action of the gear ring and gear. At this time, the transmission roller can rotate, and under the transmission cooperation of the stop block and the annular groove, the transmission ring can be driven to move upward. When the transmission ring moves upward, the support frame can be driven to move upward. When the moving cover moves upward with the support frame, the transmission rod can be driven to rotate upward. At this time, under the pulling action of the transmission rod, the moving cover can be moved to the right, which can pull the support plate to the right, and thus the positive terminal rod and the negative terminal rod can be moved to the right.

[0043] 4. In this invention, when a movement phase of the filter is completed, both the positive and negative terminals can contact the corresponding filter. If a sealing ring is installed in the filter, the positive and negative terminals remain open, and the LED will not be lit. If no sealing ring is installed in the filter, the positive terminal, the filter, and the negative terminal can form a power circuit, which will allow the LED to be powered on and lit. This prompts the operator to remove the filter and install a sealing ring.

[0044] After fixing multiple filters simultaneously, this invention can start a stepper motor to drive the multiple filters to operate, and at the same time enable the test component to move and contact the multiple filters to perform filter testing. Moreover, multiple filters can be tested at the same time, so it can effectively improve work efficiency compared to manual testing, and has good practicality. Attached Figure Description

[0055] refer to Figure 1-7 This embodiment proposes a sealing ring missing detection device, including a workbench 1, a support tube 3 fixedly installed on the top of the workbench 1, and a support platform 4 rotatably connected to the top of the support tube 3, a stepper motor 2 fixedly installed on the bottom of the workbench 1, the output shaft of the stepper motor 2 passing through the support tube 3 and fixedly connected to the bottom of the support platform 4, a clamping assembly installed on the top of the support platform 4, and multiple filters 9 clamped at equal intervals on the clamping assembly;

[0056] A slide rail 16 is fixedly installed on the top of the workbench 1, and a support plate 17 is slidably connected to the slide rail 16. A transmission component is connected to the right side of the support plate 17. The transmission component is connected to the top of the workbench 1 and the bottom of the support plate 4 respectively. A test component is installed on the top left side of the support plate 17, and the right side of the test component extends to the right side of the support plate 17.

[0057] With the above structure, after clamping multiple filters 9 simultaneously using the clamping assembly, the stepper motor 2 can be started to drive the support platform 4 to rotate. At this time, multiple filters 9 can move intermittently. When the support platform 4 moves, under the transmission cooperation of the transmission assembly, the support plate 17 can be driven to move laterally and reciprocate. This can drive the test assembly to move, making it convenient for the test assembly to dock with multiple filters 9 respectively, so as to realize the power-on test of the filters 9. This makes it convenient to test whether each filter 9 is equipped with a sealing ring, and multiple filters 9 can be tested at the same time. Therefore, when producing filters 9 in the factory, batch testing can be achieved, improving work efficiency.

[0058] In this embodiment, the clamping assembly includes a U-shaped frame 6, a pressure plate 7, multiple positioning components, and a braking component;

[0059] The U-shaped frame 6 is fixedly installed at the top center of the support platform 4, and the pressure plate 7 is slidably sleeved on the U-shaped frame 6. The positioning components are connected to the bottom of the pressure plate 7 and the top of the support platform 4 respectively, and the positioning components are clamped with the corresponding filter 9. The braking components are connected to the top of the pressure plate 7 on the inner wall of the U-shaped frame 6 respectively.

[0060] The pressure plate 7 can be moved downward by driving the braking component, thereby positioning and clamping the filter 9 under the action of the positioning component.

[0061] In this embodiment, the positioning component includes an upper clamping plate 8 and a lower clamping plate 5;

[0062] The upper clamping plate 8 is fixedly installed at the bottom of the pressure plate 7, and the lower clamping plate 5 is fixedly installed at the top of the support platform 4. The filter 9 is clamped to the corresponding upper clamping plate 8 and lower clamping plate 5 respectively.

[0063] With the cooperation of the upper clamping plate 8 and the lower clamping plate 5, the filter 9 can be positioned and clamped.

[0064] In this embodiment, the braking component includes a rotating rod 10, a pressure rod 11, a positioning ring 12, a locking rod 13, and a braking spring 14;

[0065] Rotating rod 10 is rotatably connected to the inner wall of the top left side of U-shaped frame 6, and the top end of pressure rod 11 is rotatably connected to rotating rod 10. The bottom end of pressure rod 11 is slidably connected to the top of pressure plate 7. Clamp rod 13 passes through the inner wall of the top right side of U-shaped frame 6 and is slidably connected to the inner wall of the top right side of U-shaped frame 6. Positioning ring 12 is fixedly installed on the top right side of rotating rod 10. Clamp rod 13 passes through positioning ring 12 and is clamped to positioning ring 12.

[0066] The brake spring 14 is sleeved on the clamp rod 13 and is located inside the U-shaped frame 6. The left and right ends of the brake spring 14 are fixedly connected to the clamp rod 13 and the right inner wall of the U-shaped frame 6, respectively.

[0067] Rotating the rotating rod 10 can drive the pressure rod 11 to move in an arc shape to the lower right, which can move the pressure plate 7 downward. When clamping the filter 9, the locking rod 13 can be made to engage with the positioning ring 12. Then, under the elastic force of the brake spring 14, the locking rod 13 can be moved to the left to form a locking relationship with the positioning ring 12, so that the pressure plate 7 can be limited by rotating the rod 10 and the pressure rod 11.

[0068] In this embodiment, two tension springs 15 are sleeved on the U-shaped frame 6 above the pressure plate 7, and the top and bottom ends of the tension springs 15 are fixedly connected to the top of the U-shaped frame 6 and the pressure plate 7, respectively.

[0069] The tension spring 15 can provide an upward pulling force to the pressure plate 7, which can conveniently and elastically limit the pressure plate 7 and prevent the pressure plate 7 from moving downward at will.

[0070] In this embodiment, the transmission assembly includes a rotating shaft 18, a transmission roller 19, a transmission ring 20, a stop block 31, a gear component, a telescopic component, and a transmission rod 22;

[0071] The rotating shaft 18 is rotatably connected to the top left side of the worktable 1, and the transmission roller 19 is fixedly sleeved on the rotating shaft 18. The transmission ring 20 is sleeved on the transmission roller 19, and the transmission roller 19 has a spiral annular groove. The stop block 31 is fixedly installed on the inner side wall of the transmission ring 20, and one side of the stop block 31 extends into the annular groove and engages with the inner wall of the annular groove.

[0072] The gear component is installed at the bottom of the support platform 4, and the top end of the rotating shaft 18 is connected to the gear component;

[0073] The telescopic component is installed on the left side of the transmission ring 20, and the left end of the telescopic component is connected to the right side of the support plate 17. The bottom end of the transmission rod 22 is rotatably connected to the top left side of the worktable 1, and the top end of the transmission rod 22 is connected to the telescopic component.

[0074] Under the transmission action of the gear component, the rotating shaft 18 can be driven to rotate. At this time, under the transmission cooperation of the annular groove and the stop block 31, the transmission ring 20 can be driven to perform longitudinal reciprocating motion. Under the transmission action of the transmission rod 22, the telescopic component can be operated, so that the test component can perform lateral reciprocating motion through the support plate 17.

[0075] In this embodiment, the telescopic component includes a support frame 21, a movable cover 25, a limiting rod 23, and a compression spring 24;

[0076] The support frame 21 is fixedly installed on the left side of the transmission ring 20, and the limiting rod 23 is fixedly installed on the right inner wall of the support frame 21. The left end of the limiting rod 23 extends into the movable cover 25 and is slidably connected to the inner wall of the movable cover 25. The left and right ends of the compression spring 24 are fixedly connected to the left inner wall of the movable cover 25 and the left end of the limiting rod 23, respectively. The top end of the transmission rod 22 extends into the support frame 21 and is rotatably connected to the bottom right side of the movable cover 25. The left side of the movable cover 25 is slidably connected to the bottom right side of the support plate 17.

[0077] As the support frame 21 reciprocates longitudinally with the transmission ring 20, it can drive the movable cover 25 to reciprocate laterally under the transmission cooperation of the transmission rod 22, thereby realizing the transmission of the support plate 17.

[0078] In this embodiment, the gear component includes a gear ring 32 and a gear 33;

[0079] The gear ring 32 is fixedly installed at the bottom of the support platform 4, and the gear 33 is fixedly installed at the top of the rotating shaft 18. The gear 33 meshes with the gear ring 32.

[0080] The meshing transmission of the gear ring 32 and the gear 33 can drive the rotating shaft 18 to rotate when the support platform 4 rotates.

[0081] In this embodiment, the test components include a fixing cover 26, a positive terminal connecting rod 28, a negative terminal connecting rod 29, an LED bead 27, and a battery 30;

[0082] The fixed cover 26 is fixedly installed on the top left side of the support plate 17, and the positive terminal rod 28 and the negative terminal rod 29 both penetrate the support plate 17 and are fixedly connected to the support plate 17. The battery 30 is fixedly installed inside the fixed cover 26. The left end of the positive terminal rod 28 is electrically connected to the positive terminal of the battery 30, and the left end of the negative terminal rod 29 is electrically connected to the negative terminal of the battery 30. The lamp bead 27 is fixedly installed on the left side of the fixed cover 26, and the power connection pin of the lamp bead 27 extends into the fixed cover 26 and is electrically connected to the negative terminal rod 29.

[0083] The filter 9 can be tested using the positive terminal 28 and the negative terminal 29, thereby determining whether a sealing ring is installed inside the filter 9.

[0084] This invention also proposes a detection method for a sealing ring missing detection device, comprising the following steps:

[0085] S1: Place multiple filters 9 on their respective lower clamping plates 5;

[0086] S2: Pushing the rotating rod 10 can drive the pressure plate 7 to move downward, and the upper clamping plate 8 can be used to position and clamp the filter 9;

[0087] S3: After the filter 9 is clamped, the locking rod 13 can be released. The brake spring 14, which is under force, can push the locking rod 13 through the positioning ring 12 to position the pressure plate 7 and keep the filter 9 in a fixed position and clamped.

[0088] S4: Starting the stepper motor 2 can drive multiple filters 9 to move, and at the same time drive the test components to operate, so as to realize the individual testing of multiple filters 9.

[0089] Working principle: After placing the filter 9 to be tested on the corresponding lower clamping plate 5, the rotating rod 10 can be pushed to rotate to the right, which can drive the pressure rod 11 to move in an arc shape to the lower right. At this time, the pressure plate 7 can be pushed to move downward. When the pressure plate 7 moves downward, it can drive multiple upper clamping plates 8 to move downward. When the rotating rod 10 rotates to a horizontal state, the filter 9 can be positioned and clamped under the action of the upper clamping plates 8.

[0090] After the filter 9 is positioned and clamped, the stepper motor 2 can be started to drive the support platform 4 to rotate. At this time, multiple filters 9 can rotate intermittently at a certain angle, which can facilitate the position adjustment of multiple filters 9, thereby enabling multiple filters 9 to be docked with the test component. When the support platform 4 rotates, the rotating shaft 18 can be rotated under the meshing transmission action of the gear ring 32 and the gear 33. At this time, the transmission roller 19 can be rotated, and under the transmission cooperation of the stop block 31 and the annular groove, the transmission ring 20 can be driven to move upward.

[0091] When the transmission ring 20 moves upward, it can drive the support frame 21 to move upward. When the moving cover 25 moves upward with the support frame 21, it can drive the transmission rod 22 to rotate upward. At this time, under the pulling action of the transmission rod 22, the moving cover 25 can move to the right, which can pull the support plate 17 to the right, and thus the positive terminal rod 28 and the negative terminal rod 29 can move to the right.

[0092] When a movement phase of filter 9 is completed, both the positive terminal rod 28 and the negative terminal rod 29 can contact the corresponding filter 9. If a sealing ring is installed in filter 9, the positive terminal rod 28 and the negative terminal rod 29 remain open, and the LED bead 27 will not be lit. If a sealing ring is not installed in filter 9, the positive terminal rod 28, filter 9, and negative terminal rod 29 can form a power circuit, which will energize the LED bead 27 and light it up. This indicates that the staff needs to remove this filter 9 and install a sealing ring. Furthermore, this technical solution can test multiple filters 9 at the same time, so it can effectively improve work efficiency compared to manual testing, thus having good practicality.
