Description

Technical Field

[0002] New Energy Vehicles (NEVs) refer to vehicles that use novel powertrains and are fully or partially powered by clean energy sources such as electricity and hydrogen. They primarily include battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and fuel cell vehicles (FCEVs). Pure electric new energy vehicles are gaining an increasing share of the market due to their comfort, intelligence, and energy efficiency. The production of pure electric new energy vehicles requires certain valves, such as electronic expansion valves and pressure regulating valves in battery management systems, and thermostatic valves and bypass valves in electronically controlled cooling systems. These valves typically require testing for durability under high pressure.

[0003] In the prior art, when performing pressure resistance testing on batches of valves, workers typically place the valves one by one on a conveyor and transport them to a testing device for testing. This requires operators to constantly feed material to the conveyor and then remove the valves after testing is complete, which is time-consuming and labor-intensive. To address this issue, we propose an automatic valve testing device. Summary of the Invention

DETAILED DESCRIPTION

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0029] like Figures 1-9As shown, a valve automatic detection device includes a shell 1, a sieve plate 10, a diverter plate 2, a transmission and sorting component 3, an anti-fool component 4 and a pressure detection component 5. Among them, the shell 1 mainly plays the role of support and installation, and can provide a carrier for support and installation of corresponding components. The sieve plate 10 mainly plays the role of dust removal and transmission. The diverter plate 2 mainly plays the role of diversion, and can divert and transmit the valves transmitted by the sieve plate 10. The transmission and sorting component 3 can transmit and separate the valves transmitted by the diverter plate 2. The anti-fool component 4 mainly ensures that the pressure detection component 5 only performs pressure detection on one valve at a time. The pressure detection component 5 is mainly used to detect the pressure resistance of the valve.

[0030] Specifically, if Figure 2 and Figure 6 As shown, the shell 1 includes: a first side panel 11, a second side panel 12, a bottom panel 13 and a baffle 14. The first side panel 11 and the second side panel 12 are arranged in parallel, and the bottom panel 13 is fixedly connected to the bottom of the first side panel 11, the second side panel 12 and the baffle 14. The two sides of the baffle 14 are fixedly connected to the first side panel 11 and the second side panel 12 respectively, and the top of the baffle 14 is arranged to fit the bottom of the conveyor belt assembly 31. In this way, a chamber can be defined between the first side panel 11, the second side panel 12, the bottom panel 13, the baffle 14, the screen plate 10, the diverter plate 2 and the conveyor belt assembly 31, and the chamber is used for dust collection. The side of the chamber away from the baffle 14 can be set to be open and provided with a detachable closed door to facilitate the subsequent cleaning of dust and impurities in the chamber.

[0031] In addition, if Figure 1 and Figure 2 As shown, the sieve plate 10 is obliquely arranged on the shell 1. Specifically, the two side edges of the sieve plate 10 are fixedly connected to the first side plate 11 and the second side plate 12 respectively. When in use, a batch of valves are poured into the high side of the sieve plate 10. Under the action of gravity, the valves will slide along the surface of the sieve plate 10 to the low side of the sieve plate 10. During the sliding process, the valves that were originally concentrated will tend to disperse, and in the sliding process, due to vibration, the dust or tiny impurities on the valves will fall from the filter holes on the sieve plate 10 into the chamber for collection, which can play a role in cleaning the valves and reduce the entry of dust into subsequent processes. It should be noted that the high side of the sieve plate 10 mentioned above refers to the side of the sieve plate 10 that is higher from the ground, and the low side of the sieve plate 10 refers to the side of the sieve plate 10 that is lower from the ground.

[0032] Furthermore, if Figure 2As shown, a vibrator 20 is fixedly connected to the bottom of the sieve plate 10, and the vibrator 20 is fixed to the high side of the sieve plate 10. The vibrator 20 can increase the amplitude and frequency of the sieve plate 10, and can accelerate the vibration speed and amplitude of the valve, which is conducive to the dispersion of the valve and can better clean the dust and tiny impurities on the valve, making it more convenient to use.

[0033] In addition, if Figure 1 、 Figure 4 and Figure 5 As shown, the diverter plate 2 is also tilted on the housing 1, with the upper side of the diverter plate 2 positioned adjacent to the lower side of the sieve plate 10. Specifically, the two sides of the diverter plate 2 are fixedly connected to the first side plate 11 and the second side plate 12, respectively. The diverter plate 2 is tilted, with the upper side of the diverter plate 2 positioned adjacent to the lower side of the sieve plate 10. This allows the batch valves, after being cleaned and dispersed by the sieve plate 10, to fall directly onto the diverter plate 2 and slide down along its surface.

[0034] Furthermore, the diverter plate 2 includes: a mainstream plate 21 and two secondary flow plates 22 arranged on both sides of the mainstream plate 21. The two secondary flow plates 22 are arranged parallel to the mainstream plate 21 and are located below the mainstream plate 21, and a transition plate 23 is fixedly connected between the secondary flow plate 22 and the mainstream plate 21. It should be noted that the width dimension of the mainstream plate 21 is smaller than the width dimension of the sieve plate 10, and the transition plate 23 is arranged at an angle, so that the batch valves cleaned and dispersed by the sieve plate 10 will randomly fall onto the mainstream plate 21 and the two transition plates 23, and the valves falling on the transition plate 23 will slide along the inclined surface of the transition plate 23 to the adjacent secondary flow plate 22. In this way, the valves falling on the diverter plate 2 will slide down along the surface of the mainstream plate 21 and the secondary flow plate 22 respectively, so that the valves can be further diverted and the occurrence of valve accumulation can be reduced.

[0035] In addition, if Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 9As shown, the transmission and sorting assembly 3 includes: a first partition 34, a second partition 35, a third partition 36, a fourth partition 37, a conveyor belt assembly 31, and three groups of partition assemblies 33. Among them, the first partition 34, the second partition 35, the third partition 36, and the fourth partition 37 are all arranged between the first side plate 11 and the second side plate 12 and are arranged parallel to each other. One end of the first partition 34 to the fourth partition 37 is fixedly connected to the lower side end of the diverter plate 2. In this way, flow channels 32 can be defined between the first side plate 11 and the first partition 34, between the second partition 35 and the third partition 36, and between the fourth partition 37 and the second side plate 12, that is, three flow channels 32 are defined, and the three flow channels 32 correspond to the main flow plate 21 and the two secondary flow plates 22 respectively. The conveyor belt assembly 31 is an existing technology. The conveyor belt assembly 31 is installed on the first side plate 11 and the second side plate 12. One end of the conveyor belt assembly 31 is set close to the lower side of the diverter plate 2, so that the conveyor belt assembly 31 can horizontally transport the valves transported from the main flow plate 21 and the two secondary flow plates 22 in the corresponding flow channel 32.

[0036] It should be noted that the upper surface of the conveyor assembly 31 is flush with the lower sides of the main plate 21 and the two secondary plates 22. This reduces the height difference between the main plate 21, the two secondary plates 22, and the conveyor assembly 31. Valves conveyed through the diverter plate 2 slide smoothly onto the conveyor assembly 31 for movement, thereby protecting the valves. Furthermore, the first through fourth baffles 34, 37 are positioned above the conveyor assembly 31, and the tops of the first through fourth baffles 34, 37 are elevated above the lower side of the diverter plate 2 from the ground. This effectively limits the position of the valves as they slide onto the conveyor assembly 31 and move along their corresponding flow channels 32. The width of the main plate 21 and the two secondary plates 22 can be the same as the width of the corresponding flow channels 32. The width of the flow channels 32 can be configured to allow for the simultaneous co-linear transport of two or three valves. This reduces valve accumulation while preventing the occurrence of multiple valves co-linearly across the width of the flow channel 32.

[0037] During use, after the valves randomly fall onto the main flow plate 21 and the two secondary flow plates 22 through the sieve plate 10, the corresponding valves will flow into the corresponding flow channels 32 on the conveyor belt assembly 31 along the main flow plate 21 and the two secondary flow plates 22 respectively, and move under the drive of the conveyor belt assembly 31.

[0038] The three groups of separation components 33 correspond one to one with the three flow channels 32. The separation components 33 are used to separate the valves in the corresponding flow channels 32 according to the transmission direction, so that the valves in the flow channels 32 can be transported at intervals, which is convenient for subsequent pressure testing of each valve separately.

[0039] The partition assembly 33 includes a first cylinder 331, a second cylinder 332, a fixing plate 333, and an image sensor 334. The first cylinder 331 and the second cylinder 332 are respectively fixedly connected to either side of the corresponding flow channel 32. Specifically, the first cylinder 331 and the second cylinder 332 corresponding to the flow channel 32 near the first side plate 11 are respectively fixedly connected to the first side plate 11 and the first partition plate 34. The first cylinder 331 and the second cylinder 332 corresponding to the intermediate flow channel 32 are respectively fixedly connected to the second partition plate 35 and the third partition plate 36. The first cylinder 331 and the second cylinder 332 corresponding to the flow channel 32 near the second side plate 12 are respectively fixedly connected to the fourth partition plate 37 and the second side plate 12. The first cylinder 331 and the second cylinder 332 in each partition assembly 33 can be arranged front and back along the transport direction. The telescopic ends of the first cylinder 331 and the second cylinder 332 can both extend and retract within the corresponding flow channel 32 along the width of the flow channel 32. The fixing plate 333 is fixedly connected to the top of the corresponding flow channel 32, and the image sensor 334 is fixedly connected to the fixing plate 333 for monitoring the valve in the corresponding flow channel 32. It should be noted that the automatic valve detection device also includes a controller 9, which is mainly used to receive information and send control instructions.

[0040] During use, for example, in the middle flow channel 32, after valves transported through the main flow plate 21 enter the middle flow channel 32, two or three valves may be transported collinearly within the flow channel 32, i.e., two or three valves are collinear across the width of the flow channel 32. For example, if three valves are transported collinearly, the image sensor 334 collects the corresponding information and transmits it to the controller 9 in the form of an electrical signal. After analyzing and processing the collected information, the controller 9 first activates the first cylinder 331. The telescopic end of the first cylinder 331 extends and blocks the adjacent valve, causing the adjacent valve to decelerate and disengage from the other two valves. The first cylinder 331 is then activated to release the restriction on the adjacent valve. The second cylinder 332 is then activated. The telescopic end of the second cylinder 332 extends and blocks the adjacent valve, causing the adjacent valve to decelerate and disengage from the other valve. The second cylinder 332 is then activated to release the restriction on the adjacent valve. This ensures that only one valve is transported across the width of the flow channel 32.

[0041] In addition, when the distance between two valves along the transportation direction in the flow channel 32 is too close, the image sensor 334 collects the corresponding information and transmits the information to the controller 9 in the form of an electrical signal. After analyzing and processing the collected information, the controller 9 starts the first cylinder 331 to limit the rear valve for a short time, leaving a safe distance between the valve and the front valve, and then releases the limit on the valve.

[0042] As an optional embodiment, a gap is provided between the lower sides of the diverter plate 2, communicating with the chamber. This gap serves as a dust removal mechanism. When the valve slides onto the conveyor assembly 31 through the diverter plate 2, dust left behind by the valve on the diverter plate 2 falls through the gap into the chamber for collection, reducing the amount of dust that falls onto the conveyor assembly 31. It should be noted that the size of the gap is determined based on actual conditions, with the maximum size that does not interfere with the valve sliding onto the conveyor assembly 31 being preferred.

[0043] Furthermore, as shown in the figure, the foolproof assembly 4 is used to receive valves output from the three flow channels 32 and detect the weight of the valves. When the detected weight is equal to the weight of a valve, the foolproof assembly 4 unloads the valve. When the detected weight is greater than the weight of a valve, the foolproof assembly 4 stops operating. This ensures that the pressure detection assembly 5 only performs pressure resistance testing on one valve at a time, which helps improve the reliability of the test results.

[0044] Specifically, the foolproof assembly 4 comprises a support plate 41 and three sets of pressure transfer assemblies 42. One end of the support plate 41 is positioned near the other end of the conveyor assembly 31, and the top of the support plate 41 is fixedly connected to the bottoms of the first through fourth baffles 34, 37. Three through-holes 411 are defined on the side of the support plate 41 near the conveyor assembly 31. These three through-holes 411 correspond to the three flow channels 32 and the three pressure detection assemblies 5.

[0045] like Figure 1 、 Figure 3 、 Figure 5 and Figure 8 As shown, the pressure transfer assembly 42 includes: a lifting plate 421, two mounting plates 422, a rotating shaft 423, a connecting seat 424, a pressure sensor 425, a third cylinder 426, a machine base 427, and a motor 428. The lifting plate 421 is vertically slidably connected to the corresponding through hole 411. It should be noted that the initial state of the lifting plate 421 can be located in the corresponding through hole 411, so that the valve can slide directly horizontally onto the lifting plate 421 after being transported by the conveyor assembly 31, which is beneficial for protecting the valve. The two mounting plates 422 are symmetrically fixedly connected to the bottom of the lifting plate 421. The two ends of the rotating shaft 423 are respectively fixedly connected to the two mounting plates 422. One end of the rotating shaft 423 extends to the outside of the corresponding mounting plate 422 and is fixedly connected to the motor 428. The axial direction of the rotating shaft 423 can be the same as the width direction of the flow channel 32. The top of the connecting base 424 is rotatably connected to the rotating shaft 423. The ends of the base 427 are respectively fixedly connected to the side walls of the connecting base 424 and the motor 428. The fixed end of the third cylinder 426 is fixedly connected to the bottom plate 13. The upper and lower connecting ends of the pressure sensor 425 are respectively fixedly connected to the telescopic end of the third cylinder 426 and the bottom of the connecting base 424.

[0046] During use, when a valve slides through the corresponding flow channel 32 onto the corresponding lifting plate 421, the pressure sensor 425 detects the weight of the valve on the lifting plate 421. When the detected weight of the valve on the lifting plate 421 is equal to or approximately equal to the weight of one valve, the pressure sensor 425 transmits this information to the controller 9, which controls the third cylinder 426 to extend and retract downward, causing the lifting plate 421 to lower the corresponding valve. When it reaches a preset height, the third cylinder 426 is stopped and the motor 428 is activated. The motor 428 rotates the lifting plate 421 via the shaft 423 and the mounting plate 422, thereby removing the valve from the corresponding lifting plate 421. It should be noted that during the operation of the foolproofing assembly 4, the conveyor belt assembly 31 can be paused to prevent the next valve from falling directly into the through-hole 411 during the operation of the foolproofing assembly 4. Furthermore, the valve can be removed toward the side away from the conveyor belt assembly 31, providing more space and facilitating subsequent processes.

[0047] It should be noted that, in the vertical direction, the cross-sectional dimension of the lifting plate 421 is larger than the cross-sectional dimension of the valve, so that the valve can slide onto the lifting plate 421 more accurately.

[0048] As an optional embodiment, Figure 1 As shown, three alarms 8 can be set on the support plate 41. The three alarms 8 correspond one-to-one to the three pressure transfer components 42. The alarms 8 are connected to the controller 9. When the weight on the lifting plate 421 detected by the corresponding pressure sensor 425 is greater than the weight of a valve, the controller 9 controls the alarm 8 to sound an alarm to improve safety.

[0049] In addition, if Figure 1 、 Figure 3 and Figure 5 As shown, there are three groups of pressure detection components 5 , which are arranged on the housing 1 and correspond to the three flow channels 32 , for performing pressure detection on the valves discharged from the foolproof component 4 .

[0050] Specifically, the pressure detection assembly 5 includes: a mounting base 51, a load-bearing plate 52, a first hydraulic cylinder 53, a second hydraulic cylinder 54, and a pressure plate 55. The mounting base 51 is fixedly connected to the bottom of the support plate 41, and the load-bearing plate 52 is rotatably connected to the mounting base 51 on the side close to the lifting plate 421. The direction of the rotation axis 423 of the load-bearing plate 52 can be the same as the width direction of the flow channel 32. The fixed end of the first hydraulic cylinder 53 is fixedly connected to the bottom plate 13, and the telescopic end of the first hydraulic cylinder 53 is arranged in contact with the bottom of the side of the load-bearing plate 52 away from the lifting plate 421. The second hydraulic cylinder 54 is fixedly connected to the support plate 41, and the telescopic end of the second hydraulic cylinder 54 selectively applies pressure toward the top of the load-bearing plate 52.

[0051] After the valve is removed via the lifting plate 421, it falls onto the bearing plate 52. At this point, the second hydraulic cylinder 54 is activated, driving the pressure plate 55 to apply pressure to the valve to test its compressive strength. After testing is complete, the second hydraulic cylinder 54 is activated to lift the pressure plate 55 away from the valve, and the first hydraulic cylinder 53 is activated to lower its telescopic end. The bearing plate 52 then rotates, allowing the tested valve to be removed. It should be noted that the telescopic lengths of the first and second hydraulic cylinders 53, 54 are set according to the specific operating conditions.

[0052] As an optional embodiment, Figure 1 As shown, the automatic valve inspection equipment also includes three inclined stripper plates 6. These stripper plates 6 are fixedly connected to the base plate 13 and correspond one to each of the three bearing plates 52. The high side of each stripper plate 6 is positioned closer to the side of the bearing plate 52, away from the lifting plate 421. The stripper plates 6 primarily serve to transport the valves. After being discharged from the corresponding bearing plate 52, the valves fall onto the high side of the stripper plates 6 and slide out along the surface of the stripper plates 6, thereby better protecting the valves. Furthermore, the discharge direction of the stripper plates 6 can be adjusted according to actual operating conditions, facilitating subsequent collection of the valves.

[0053] Furthermore, as shown in the figure, two limit plates 7 are symmetrically fixedly connected to the main flow plate 21 on both sides along the transmission direction, and the limit plates 7 are arranged near the conveyor belt assembly 31. The limit plates 7 mainly play a limiting role. The limit plates 7 are arranged near the conveyor belt assembly 31. Since there is an invalid space between the first baffle 34 and the second baffle 35 of the valve, and between the second baffle 35 and the third baffle 36 and the fourth baffle 37, the design of the limit plates 7 is to prevent the valve from falling onto the transition plate 23 when approaching the conveyor belt assembly 31, and then falling into the invalid space, thereby ensuring that the valve eventually falls into the three flow channels 32.

[0054] In addition, as shown in the figure, the valve automatic detection equipment also includes a limit rod 30. The axis of the limit rod 30 is set perpendicular to the transportation direction of the conveyor belt assembly 31, that is, the same as the width direction of the flow channel 32. The limit rod 30 slides through the first side plate 11, the second side plate 12, the first partition 34 to the fourth partition 37, and the distance between the limit rod 30 and the top of the conveyor belt assembly 31 is greater than the height of one valve and less than the height of two valves. The specific height can be set according to the actual working conditions. The limit rod 30 mainly plays a limiting role. When multiple valves are stacked in the vertical direction, the limit rod 30 can block the upper valve, which is conducive to the interval transmission of the valves in the flow channel 32.

[0055] It should be noted that the actuators, such as the first air cylinder 331, the second air cylinder 332, the image sensor 334, the conveyor belt assembly 31, the vibrator 20, the motor 428, the third air cylinder 426, the first hydraulic cylinder 53, the second hydraulic cylinder 54, and the alarm 8, are all electrically connected to the controller 9, so that the controller 9 can receive information and send instructions.

The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
