[0002] As an indispensable key component in the engine lubrication system, the oil filter's main function is to filter impurities in the oil and maintain the cleanliness of the oil, thereby effectively extending the service life of the engine. The sealing performance of the oil filter has a vital impact on the normal operation and performance stability of the engine. Good sealing performance can prevent the filter from leaking hydraulic oil when the engine is working, which not only helps to keep the internal environment of the engine clean, but also avoids mechanical failures or safety hazards caused by oil leakage.

[0003] However, in the context of mass production of filters, the sealing test has become a key factor restricting production efficiency and capacity. Taking the patented device with publication number CN110779663B as an example, although it can realize the sealing test of filters, its operation process is particularly cumbersome and time-consuming.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0020] A filter assembly sealing detection device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 8 As shown, a filter assembly sealing detection device according to an embodiment of the present invention comprises a synchronous drive device 1, an automatic loading and unloading component 2, a pressure detection component 3, a water immersion detection component 4 and a PLC console 5, wherein: the synchronous drive device 1 comprises a lifting slide 14 and a lifting gear rod 15, the lifting slide 14 and the lifting gear rod 15 are synchronously lifted and lowered vertically under the drive of the hydraulic telescopic rod 13, the automatic loading and unloading component 2 comprises a chain plate conveyor 20 and a sliding material seat component 24, a one-way intermittent driving mechanism 25 is provided on the chain plate conveyor 20, and is connected to the lifting gear rod 15, the sliding material seat component 24 is evenly arranged on the chain plate conveyor 20, the pressure detection component 3 and the water immersion detection component 4 are respectively arranged on the surface of the lifting slide 14 and the inner wall of the chain plate conveyor 20, both of which accurately correspond to a set of specific sliding material seat component 24 positions, and the PLC console 5 is seamlessly connected with the hydraulic telescopic rod 13, the pressure detection component 3 and the water immersion detection component 4 through an efficient bus, so as to realize rapid data transmission and accurate reception of control instructions.

[0022] It should be noted that in order to further improve the efficiency of loading and unloading and reduce labor intensity, the device is also equipped with an intelligent pick-and-place mechanism 27. The intelligent pick-and-place mechanism 27 has high-precision operating capabilities and is responsible for accurately placing the filter assembly to be tested inside the sliding material seat assembly 24, and after the test is completed, the filter assembly is also removed from the sliding material seat assembly 24 with high precision. This design ensures the automated processing of the filter assembly in the entire testing process, thereby improving production efficiency and accuracy. Specifically, the intelligent pick-and-place mechanism 27 includes a loading intelligent robot 271 and a unloading intelligent robot 272. The loading intelligent robot 271 and the unloading intelligent robot 272 are respectively fixedly connected to the ground and located on the outside of the conveyor frame 21. The PLC console 5 is seamlessly connected to the loading intelligent robot 271 and the unloading intelligent robot 272 through an efficient bus, thereby realizing rapid data transmission and accurate reception of control instructions.

[0023] It should also be noted that in order to ensure that the transmission chain 23 in the chain-plate conveyor 20 smoothly conveys the chain plate 241, a tensioning support assembly 26 is also provided on the surface of the conveyor frame 21. The tensioning support assembly 26 is used to adjust the tension of the transmission chain 23 to improve the position accuracy and stability during detection. The tensioning support assembly 26 includes a base 261 and an adjusting screw 262. Specifically, the base 261 is symmetrically fixedly connected to the outer surface of one end of the conveyor frame 21 away from the unidirectional intermittent drive mechanism 25. The two ends of the transmission gear rack 22 corresponding to the position of the base 261 respectively pass through the outside of the conveyor frame 21 and are slidably connected to the inner wall of the base 261. The adjusting screw 262 is rotatably connected to the inner wall of the base 261 and is threadedly connected to the inner wall of one end of the transmission gear rack 22 that passes through the outside of the conveyor frame 21. By twisting the adjusting screw 262, the position of one group of transmission gear racks 22 can be changed, thereby synchronously changing the tension of the transmission chain 23.

[0024] It can be understood that in order to facilitate the synchronous lifting of the lifting slide 14 and the lifting gear rod 15, a main frame 11 is arranged on the inner side of the chain plate conveyor 20, and a lifting plate frame 12 that can slide up and down is arranged on the inner wall of the main frame 11. The hydraulic telescopic rod 13 is arranged on the top of the main frame 11, and one end of the hydraulic telescopic rod 13 passes through the interior of the main frame 11 and is fixedly connected to the top of the lifting plate frame 12. The lifting slide 14 and the lifting gear rod 15 are respectively slidably connected to the outer surface of the main frame 11 and are fixedly connected to the lifting plate frame 12.

[0025] Specifically, when in use, the oil filter assembly to be tested is accurately and orderly placed in the sliding material seat assembly 24 by the loading intelligent robot 271. When the oil filter assembly corresponds to the position of the pressure detection assembly 3, the hydraulic telescopic rod 13 receives the command from the PLC console 5 and performs operations according to the command. During a single operation of the hydraulic telescopic rod 13, it first drives the lifting slide 14 and the lifting gear rod 15 to descend synchronously. The descent of the lifting slide 14 simultaneously drives the pressure detection assembly 3 to descend. During the descent of the lifting slide 14, the pressure detection assembly 3 accurately abuts the top of the filter assembly, and then drives the filter assembly and the sliding material seat assembly 24 to slide down smoothly until they completely enter the water immersion detection assembly 4 for detection. When the filter assembly and the sliding material seat assembly 24 enter the water immersion detection assembly 4, the water immersion detection assembly 4 The detection component 4 and the pressure detection component 3 respectively perform sealing performance tests on the filter assembly by the water immersion method and the pressure change method, so as to realize automatic sealing performance testing of the filter assembly. After the set time, the hydraulic telescopic rod 13 drives the lifting slide 14 and the lifting gear rod 15 to rise synchronously according to the instruction. When the lifting gear rod 15 rises, it will synchronously trigger the one-way intermittent drive mechanism 25 to start working. Then the one-way intermittent drive mechanism 25 will work and drive the chain plate conveyor 20 to operate accurately, so that the multiple groups of sliding material seat assemblies 24 evenly arranged on the chain plate conveyor 20 can be orderly and uniformly moved to a preset workstation at the unloading end of the chain plate conveyor 20, so as to facilitate the detection of the next group of filter assemblies, and the detected filter assemblies will be removed from the sliding material seat assembly 24 by the unloading intelligent robot 272.

[0026] In one embodiment of the present invention, Figure 1-Figure 2 As shown, there are two groups of lifting slides 14 , lifting gear rods 15 and chain plate conveyors 20 . The height of the lifting slides 14 is higher than that of the lifting gear rods 15 , and the stroke of the lifting slides 14 is consistent with that of the lifting gear rods 15 .

[0027] Specifically, the number of the lifting slide 14, the lifting gear rod 15 and the chain plate conveyor 20 is further explained. Setting two groups can further improve the work efficiency. The height offset setting of the lifting slide 14 and the lifting gear rod 15 respectively adapts to the height of the sliding material seat assembly 24 and the one-way intermittent drive mechanism 25, and the structure is more reasonable.

[0028] In one embodiment of the present invention, Figure 4As shown, the sliding material seat assembly 24 includes a through hole 242, a limiting guide frame 243 and a material frame 244, wherein: the through hole 242 is opened at the top center of the chain plate 241 in the chain plate conveyor 20, the limiting guide frame 243 is fixedly connected to the inner wall of the through hole 242, one end of the limiting guide frame 243 passes through the top of the chain plate 241, and the other end of the limiting guide frame 243 passes through the bottom of the chain plate 241 and is fixedly connected to the bottom of the chain plate 241, the material frame 244 is located on the inner side of the limiting guide frame 243, the material frame 244 is vertically slidably connected to the inner wall of the limiting guide frame 243, and a first spring is fixedly connected to the inner wall of the limiting guide frame 243, and the filter assembly is placed inside the material frame 244, and the shape of the filter assembly is adapted to the internal size of the material frame 244.

[0029] Specifically, the structure and connection relationship of the sliding material seat assembly 24 are further explained. The filter assembly is placed in the material frame 244. After the top of the filter assembly is squeezed, it will synchronously drive the material frame 244 to descend along the inner wall of the limiting guide frame 243 and compress the first spring until it enters the water immersion detection assembly 4. When the pressure disappears, the filter assembly and the material frame 244 will automatically reset under the action of the elastic force of the first spring, so that the filter assembly can be removed from the water immersion detection assembly 4. During pressure testing, the first spring will also provide a reaction force to the material frame 244, so that the filter assembly can be more tightly abutted against the sealing cover 33, thereby further improving the connection sealing performance during testing.

[0030] In one embodiment of the present invention, Figure 3 and Figure 5 As shown, the one-way intermittent drive mechanism 25 includes a transmission ratchet 251, a rotating shaft 252, a driving gear 253, a synchronous arm 254, a first ratchet 255 and a second ratchet 256, wherein: the rotating shaft 252 is rotatably connected to the surface of the conveyor frame 21 in the chain plate conveyor 20, the transmission ratchet 251 is rotatably connected to the surface of the conveyor frame 21 and is sleeved on the outside of the rotating shaft 252, one end of the transmission ratchet 251 is fixedly connected to one end of the central axis of the transmission gear frame 22 in the chain plate conveyor 20, the driving gear 253 is fixedly connected to the surface of the rotating shaft 252 and is located on the outside of the transmission ratchet 251, and the lifting mechanism 254 is a plurality of intermittent drive mechanisms. The gear-dropping rod 15 is located on one side of the driving gear 253 and is meshed with the driving gear 253. The synchronization arm 254 is fixedly connected to the surface of the driving gear 253 and is sleeved on the outside of the rotating shaft 252. One end of the first pawl 255 is rotatably connected to the surface of the synchronization arm 254, and the other end of the first pawl 255 is meshed with the driving gear 253. The second pawl 256 is rotatably connected to the surface of the conveyor frame 21 and is meshed with the driving gear 253. A second spring is fixedly connected between the surface of the first pawl 255 and the surface of the synchronization arm 254 and between the second pawl 256 and the surface of the conveyor frame 21.

[0031] Specifically, the structure and connection relationship of the one-way intermittent drive mechanism 25 are further described. When in use, the lifting gear rod 15 descends and synchronously drives the driving gear 253 to rotate forward, and the driving gear 253 rotates forward and synchronously drives the synchronization arm 254 to rotate forward, and the synchronization arm 254 rotates forward and synchronously drives the first pawl 255 to move downward, and one end of the pawl 255 slides and connects to the surface of the transmission ratchet 251, and the second pawl 256 meshes with the transmission ratchet 251 to ensure that the position of the transmission ratchet 251 remains unchanged, the lifting gear rod 15 rises and synchronously drives the driving gear 253 to reverse, the driving gear 253 reverses and synchronously drives the synchronization arm 254 to reverse, the synchronization arm 254 reverses and synchronously drives the first pawl 255 to move upward, and the first pawl 255 moves upward and engages with the transmission ratchet 25 1 meshes and connects, and synchronously pushes the transmission ratchet 251 to move so as to rotate the set angle. The rotation of the transmission ratchet 251 synchronously drives the transmission gear rack 22 to rotate. The rotation of the transmission gear rack 22 synchronously drives the transmission chain 23 to move. The movement of the transmission chain 23 synchronously drives the chain plate 241, the sliding material seat assembly 24 and the filter assembly to move, so as to realize the automatic loading of the next group of oil filter assemblies to be tested and the automatic unloading of the tested oil filter assemblies. During the rotation of the transmission ratchet 251, the second pawl 256 slides and connects over the surface of the transmission ratchet 251. After the transmission ratchet 251 stops rotating, the second pawl 256 meshes with the transmission ratchet 251 again, so as to limit the position of the transmission ratchet 251. The overall operation is simple and the use effect is good.

[0032] In one embodiment of the present invention, Figure 7 As shown, the pressure detection assembly 3 includes a fixed cylinder 31, a three-way pipe 32, a sealing cover 33, an air inlet disc 34, a pressure measuring air pipe 35 and a remote pressure gauge 36, wherein: the fixed cylinder 31 is fixedly connected to the inner wall of the lifting slide 14, the three-way pipe 32 and the sealing cover 33 are respectively fixedly connected to the top of the fixed cylinder 31 and the bottom of the fixed cylinder 31, the air inlet disc 34 is threadedly connected to the inner wall of the sealing cover 33, the pressure measuring air pipe 35 is threadedly connected to the inner wall of the air inlet disc 34, one end of the pressure measuring air pipe 35 passes through the bottom of the sealing cover 33, and the pressure measuring air pipe 35 is threadedly connected to the inner wall of the air inlet disc 34. The other end of the tube 35 passes through the interior of the fixed cylinder 31 and is fixedly connected to a remote pressure gauge 36. An intake solenoid valve is provided on the surface of the input end of the three-way tube 32, and an exhaust solenoid valve is provided on the surface of one group of output ends of the three-way tube 32. A gas supply hose is fixedly connected between the other group of output ends of the three-way tube 32 and the input end of the intake disk 34. The PLC console 5 is seamlessly connected to the remote pressure gauge 36, the intake solenoid valve and the exhaust solenoid valve through an efficient bus, thereby realizing rapid data transmission and accurate reception of control instructions.

[0033] It should be noted that, in order to ensure the verticality of the fixed cylinder 31 during lifting and lowering, the fixed cylinder 31 is also slidably connected to the inner wall of the main frame 11 .

[0034] It should also be noted that in order to improve the sealing performance after the bottom of the sealing cover 33 abuts against the top of the material frame 244, an annular limit ring is provided on the top of the material frame 244, and an O-ring is provided on the surface of the annular limit ring. The sealing cover 33 is sleeved on the outside of the annular limit ring and abuts against the top of the material frame 244. When the O-ring comes into contact with the detection liquid, it will expand, thereby blocking the gap between the surface of the annular limit ring and the inner wall of the sealing cover 33, thereby effectively improving the sealing performance.

[0035] Specifically, the structure and connection relationship of the pressure detection component 3 are further explained. When in use, the hydraulic telescopic rod 13 receives the command sent by the PLC console 5 and operates according to the command. The operation of the hydraulic telescopic rod 13 drives its output end to extend downward until its output end moves down to the maximum stroke value and then stops running for 40 seconds. In this process, the output end of the hydraulic telescopic rod 13 extends and synchronously drives the lifting plate frame 12 to descend along the inner wall of the main frame 11. The descent of the lifting plate frame 12 synchronously drives the lifting slide 14 and the lifting gear rod 15 to descend along the outer surface of the main frame 11 respectively. The descent of the lifting slide 14 synchronously drives the fixed cylinder 31 to descend, and the descent of the fixed cylinder 31 synchronously drives the fixed cylinder 31 to descend. The sealing cover 33 is driven to descend step by step. When the bottom of the sealing cover 33 contacts the top of the oil filter assembly inside the material frame 244, the bottom of the sealing cover 33 is connected with the top of the oil filter assembly and is sleeved on the outside of the oil inlet hole of the oil filter assembly. At this time, the gap between the bottom of the air inlet plate 34 and the top of the oil filter assembly forms a sealed cavity, and one end of the pressure measuring air pipe 35 is inserted into the oil outlet hole of the oil filter assembly. As the lifting slide 14 continues to descend, the sealing cover 33 also descends, and synchronously squeezes the oil filter assembly and the material frame 244 to descend along the inner wall of the limiting guide frame 243, and compresses the first spring inside the limiting guide frame 243. When the output end of the hydraulic telescopic rod 13 extends downward to the maximum stroke, the hydraulic telescopic rod 13 stops running for 40 seconds. At this time, the material frame 244, the oil filter assembly and the sealing cover 33 have all moved down to the inside of the glass container 41 and are immersed below the liquid level of the detection liquid. Then the air intake solenoid valve is opened for 4 seconds (the specific number of seconds depends on the specifications of the oil filter assembly). The external gas is input from the position of the three-way pipe 32, and then output through the air supply hose and the air intake plate 34. It enters the inside of the oil filter assembly through the oil inlet hole of the oil filter assembly, and then is discharged from the inside of the oil filter assembly to the oil outlet hole, and finally enters the inside of the pressure measuring air pipe 35. The remote pressure gauge 36 is The pressure inside the oil filter assembly is detected in real time. The intake solenoid valve is closed according to the command after 4 seconds. At this time, the gas inside the oil filter assembly is consistent with the set total gas volume, and then enters a 30-second pressure maintenance stage. During this 30-second process, the remote pressure gauge 36 detects the pressure inside the oil filter assembly in real time. If the pressure decreases over time, it means that the sealing performance of the oil filter assembly is unqualified, and the specific value will be directly displayed on the display screen in the PLC console 5. If the pressure value remains unchanged or changes little, it means that the sealing performance of the oil filter assembly is qualified, and the specific value will also be directly displayed on the display screen in the PLC console 5.

[0036] In one embodiment of the present invention, Figure 8As shown, the water immersion detection component 4 includes a support frame 40, a glass container 41, a bubble detection mechanism 42 and a constant temperature heating tube 43, wherein: the support frame 40 is fixedly connected to the inner wall of the conveyor frame 21 and is located between the two sets of transmission gear racks 22, the glass container 41 is fixedly connected to the surface of the support frame 40 and corresponds to the position of the limiting guide frame 243, the bubble detection mechanism 42 is evenly fixedly connected to the inner wall of the glass container 41, the constant temperature heating tube 43 is fixedly connected to the inner bottom wall of the glass container 41, and the PLC console 5 is seamlessly connected to the bubble detection mechanism 42 and the constant temperature heating tube 43 through a high-efficiency bus, thereby realizing rapid data transmission and accurate reception of control instructions.

[0037] Specifically, before maintaining pressure for 30 seconds, the constant temperature heating tube 43 heats the test liquid according to the instruction and keeps it at the set temperature. The bubbles initially adhering to the surface of the oil filter assembly when it enters the test liquid are eliminated by heating. When the temperature reaches the set temperature, the initially adhering bubbles will be reduced or disappear due to the increase in temperature. If the sealing performance is qualified, there will be no bubbles on the surface of the oil filter assembly after the 30 seconds of pressure maintenance. If the sealing performance is unqualified, there will still be bubbles on the surface of the oil filter assembly after the 30 seconds of pressure maintenance. After the 30-second pressure maintenance, the camera in the bubble detection mechanism 42 operates according to the instruction to shoot the surface of the oil filter assembly, and the bubble detection module in the bubble detection mechanism 42 analyzes the shot image, so as to more accurately detect the sealing of the oil filter, avoid unclear observation by workers, and cause the test result to be incorrect. Inaccurate. It should be noted that the shooting time is set to 2 seconds. After the 2-second shooting time, the exhaust solenoid valve is opened for 4 seconds according to the instruction to discharge the gas inside the oil filter assembly. After 4 seconds, the time is exactly the same as the 40 seconds when the hydraulic telescopic rod 13 stops running. After 40 seconds, the hydraulic telescopic rod 13 drives its output end to reset according to the instruction. The reset of the hydraulic telescopic rod 13 synchronously drives the lifting slide 14 and the lifting gear rod 15 to reset. The reset of the lifting slide 14 synchronously drives the fixing cylinder 31 and the sealing cover 33 to reset. During the resetting process of the sealing cover 33, its squeezing pressure on the top of the oil filter assembly gradually decreases as it rises, so that the oil filter assembly automatically and slowly resets under the elastic force of the first spring, and gradually moves out of the glass container 41. When the sealing cover 33 is completely reset, the oil filter assembly and the material frame 244 are all moved out of the glass container 41.

[0038] In one embodiment of the present invention, Figure 8 As shown, the length of the support frame 40 corresponds to the position of three groups of limiting guide frames 243, and the surface of the support frame 40 is in the same horizontal plane as the top of the glass container 41 and the bottom of the limiting guide frame 243.

[0039] Specifically, the glass container 41 described in this embodiment is arranged at the center position of the surface of the support frame 40 and corresponds to the position of the sealing cover 33. When the sealing cover 33 presses the material frame 244, the support frame 40 can effectively support the bottom of the three groups of limiting guide frames 243, significantly improving the position accuracy and stability during the detection operation, and the use effect is good.

[0040] In one embodiment of the present invention, Figure 8 As shown, there are four groups of bubble detection mechanisms 42, which are respectively arranged on the four inner walls of the glass container 41. The bubble detection mechanism 42 includes a bubble detection module and a camera. The camera is electrically connected to the bubble detection module. The bubble detection module and the camera are both located below the liquid level of the detection liquid in the glass container 41.

[0041] It is understandable that the camera can take pictures under the liquid surface of the test liquid and analyze the captured images through the bubble detection module, so as to more accurately detect the sealing of the oil filter and avoid inaccurate test results due to unclear observation by workers.

[0042] Specifically, the bubble detection mechanism 42 is carefully configured into four groups, each group is accurately deployed on an inner wall of the glass container 41, realizing all-round and no-dead-angle bubble detection inside the container. This layout ensures that no matter where the bubbles are generated in the container, they can be detected promptly and accurately, thereby improving the comprehensiveness and efficiency of the detection. At the same time, the coordinated work of the four groups of detection mechanisms also enhances the reliability and stability of the detection results.

[0043] In summary, the filter assembly sealing detection equipment of the embodiment of the present invention realizes the comprehensive automation of the filter assembly sealing performance detection, and integrates efficient loading and unloading operation functions, which completely innovates the traditional manual operation mode, not only greatly reduces the labor intensity of workers, but also significantly improves work efficiency, making the production process smoother and more efficient. Through the application of automation technology, the present invention effectively reduces human errors and losses in the production process, thereby reducing production costs. At the same time, the introduction of automated production lines significantly improves the overall production capacity of the production line, allowing enterprises to respond to market demands more quickly and enhance market competitiveness.
