Description
Technical Field
[0001] This invention relates to the field of valve manufacturing and processing technology, and more specifically, to an automatic valve testing device. Background Technology
[0002] New energy vehicles (NEVs) refer to automobiles that use new power systems and are driven entirely or partially by clean energy sources such as electricity and hydrogen. They mainly include battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and fuel cell electric vehicles (FCEVs). Battery electric NEVs are gaining an increasingly larger market share due to their comfort, intelligence, and energy efficiency. The production process of battery electric NEVs requires the use of various valves. For example, electronic expansion valves and pressure regulating valves are needed in battery management systems, while thermostatic valves and bypass valves are needed in electronically controlled cooling systems. These valves typically require testing for durability under high pressure.
[0003] In related technologies, when conducting pressure resistance tests on batches of valves, workers typically place the valves sequentially on a conveyor belt and transport them to a testing device for testing. This requires operators to continuously feed materials onto the conveyor belt, and after the valves are tested, workers must remove them, which is time-consuming and labor-intensive. Therefore, we propose an automatic valve testing device. Summary of the Invention

The pressure transfer components include: a lifting plate, two mounting plates, a rotating shaft, a connecting seat, a pressure sensor, a third cylinder, a base, and a motor. The lifting plate is vertically slidably connected in the corresponding through holes. The two mounting plates are symmetrically fixedly connected to the bottom of the lifting plate.

[0016] 1. This invention can initially disperse batch valves and clean dust by setting an inclined sieve plate. In addition, the setting of the main flow plate and two secondary flow plates can further disperse batch valves. Combined with the transfer and sorting components to separate the valves in the three flow channels, it is beneficial to realize the continuous interval transportation of batch valves. Moreover, the pressure detection component can perform pressure resistance testing on only one valve at a time, which improves the detection speed and the reliability of the detection results.

Detailed Implementation
[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.
[0029] like Figures 1-9As shown, an automatic valve testing device includes a housing 1, a sieve plate 10, a flow divider 2, a conveying and sorting assembly 3, a foolproof component 4, and a pressure detection assembly 5. The housing 1 primarily serves as a support and mounting component, providing a carrier for supporting and mounting the corresponding parts. The sieve plate 10 primarily functions for dust removal and conveying. The flow divider 2 primarily functions for diverting flow, separating and conveying valves received from the sieve plate 10. The conveying and sorting assembly 3 can convey and separate valves received from the flow divider 2. The foolproof component 4 primarily ensures that the pressure detection assembly 5 performs pressure testing on only one valve at a time. The pressure detection assembly 5 is mainly used to test the pressure resistance of the valves.
[0030] Specifically, such as Figure 2 and Figure 6 As shown, the housing 1 includes a first side plate 11, a second side plate 12, a bottom plate 13, and a baffle 14. The first side plate 11 and the second side plate 12 are arranged in parallel, and the bottom plate 13 is fixedly connected to the bottom of the first side plate 11, the second side plate 12, and the baffle 14. The two sides of the baffle 14 are fixedly connected to the first side plate 11 and the second side plate 12 respectively, and the top of the baffle 14 is disposed against the bottom of the conveyor belt assembly 31. In this way, a chamber can be defined between the first side plate 11, the second side plate 12, the bottom plate 13, the baffle 14, the screen plate 10, the diverter plate 2, and the conveyor belt assembly 31. The chamber is used for dust collection. The side of the chamber away from the baffle 14 can be set as an opening and equipped with a removable sealing door to facilitate subsequent cleaning of dust and impurities inside the chamber.
[0031] In addition, such as Figure 1 and Figure 2 As shown, the sieve plate 10 is inclinedly mounted on the housing 1. Specifically, the two sides of the sieve plate 10 are fixedly connected to the first side plate 11 and the second side plate 12, respectively. In use, a batch of valves is poured into the higher side of the sieve plate 10. Under the influence of gravity, the valves slide down the surface of the sieve plate 10 to the lower side. During this sliding process, the valves, which were originally concentrated, tend to disperse. Furthermore, due to vibration, dust or small impurities on the valves fall into the chamber through the filter holes on the sieve plate 10 for collection, thus cleaning the valves and reducing dust entering subsequent processes. It should be noted that the higher side of the sieve plate 10 refers to the side of the sieve plate 10 that is higher from the ground, and the lower side of the sieve plate 10 refers to the side of the sieve plate 10 that is lower from the ground.
[0032] Furthermore, such as 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, which can accelerate the vibration speed and amplitude of the valve. This is beneficial for the dispersion of the valve and can better clean the dust and small impurities on the valve, making it more convenient to use.
[0033] In addition, such as Figure 1 , Figure 4 and Figure 5 As shown, the flow divider 2 is also inclinedly disposed on the housing 1, with its higher side close to the lower side of the sieve plate 10. Specifically, the two sides of the flow divider 2 are fixedly connected to the first side plate 11 and the second side plate 12, respectively. The flow divider 2 is inclined, and its higher side is close to the lower side of the sieve plate 10, so that after being cleaned and dispersed by the sieve plate 10, the batch valves will fall directly onto the flow divider 2 and slide down its surface.
[0034] Furthermore, the diversion plate 2 includes a main flow plate 21 and two secondary flow plates 22 disposed on both sides of the main flow plate 21. The two secondary flow plates 22 are arranged parallel to the main flow plate 21 and located below the main flow plate 21, and a transition plate 23 is fixedly connected between the secondary flow plates 22 and the main flow plate 21. It should be noted that the width of the main flow plate 21 is smaller than the width of the sieve plate 10, and the transition plate 23 is inclined. In this way, the batch of valves cleaned and dispersed by the sieve plate 10 will randomly fall onto the main flow plate 21 and the two transition plates 23. The valves falling onto the transition plate 23 will slide down the inclined surface of the transition plate 23 onto the adjacent secondary flow plate 22. Thus, the valves falling onto the diversion plate 2 will slide down the surfaces of the main flow plate 21 and the secondary flow plates 22 respectively, thereby further diverting the valves and reducing the occurrence of valve accumulation.
[0035] In addition, such as Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9As shown, the transfer 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 sets of separating assemblies 33. The first partition 34, second partition 35, third partition 36, and fourth partition 37 are all disposed between the first side plate 11 and the second side plate 12 and are arranged parallel to each other. One end of each of the first partition 34 to the fourth partition 37 is fixedly connected to the lower end of the diverter plate 2. Thus, 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, i.e., three flow channels 32 are defined, each corresponding to the main flow plate 21 and the two secondary flow plates 22. The conveyor belt assembly 31 is 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. In this way, the conveyor belt assembly 31 can horizontally convey the valves delivered from the main flow plate 21 and the two secondary flow plates 22 in the corresponding flow channels 32.
[0036] It should be noted that the upper surface of the conveyor belt assembly 31 is flush with the lower sides of the main flow plate 21 and the two secondary flow plates 22. This reduces the height difference between the main flow plate 21 and the two secondary flow plates 22 and the conveyor belt assembly 31. Valves conveyed by the diverter plate 2 will smoothly slide onto the conveyor belt assembly 31 for movement, thereby protecting the valves. Furthermore, the first partition plate 34 to the fourth partition plate 37 are all positioned above the conveyor belt assembly 31, and the height of the top of the first partition plate 34 to the fourth partition plate 37 is higher than the height of the lower end of the diverter plate 2 from the ground. This allows the flow channel 32 to effectively limit the valve's movement when it slides onto the conveyor belt assembly 31 and moves along the corresponding flow channel 32. The width of the main flow plate 21 and the two secondary flow plates 22 can be the same as the width of the corresponding flow channel 32. The width of the flow channel 32 can be set to allow two to three valves to be transported simultaneously in a collinear manner. This reduces valve accumulation and prevents more valves from being collinear in the width direction of the flow channel 32 simultaneously.
[0037] In use, after the valves fall randomly onto the main flow plate 21 and the two secondary flow plates 22 through the screen 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, and move under the drive of the conveyor belt assembly 31.
[0038] The three sets 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 facilitates the pressure testing of each valve individually in the later stage.
[0039] The separating 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 both sides 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 middle 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, and the first cylinder 331 and the second cylinder 332 in each set of separating assemblies 33 can be arranged back and forth along the transmission direction. The telescopic ends of the first cylinder 331 and the second cylinder 332 can extend and retract within the corresponding flow channel 32 along the width direction of the flow channel 32. A mounting plate 333 is fixedly connected to the top of the corresponding flow channel 32, and an image sensor 334 is fixedly connected to the mounting plate 333 for monitoring the valve within the corresponding flow channel 32. It should be noted that the automatic valve detection equipment also includes a controller 9, which is mainly used to receive information and send control commands.
[0040] In use, for example, with the middle flow channel 32, after the valves delivered by the main flow plate 21 enter the middle flow channel 32, two or three valves may collinearly transport within the flow channel 32, that is, two or three valves are collinear in the width direction of the flow channel 32. For example, if three valves are collinearly transporting, 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 first drives the first cylinder 331 to actuate. The telescopic end of the first cylinder 331 extends and blocks the adjacent valve. At this time, the adjacent valve will decelerate and disengage from the other two valves. Then, the first cylinder 331 is driven to release the restriction on the adjacent valve. Then, the second cylinder 332 is driven. The telescopic end of the second cylinder 332 extends and blocks the adjacent valve. At this time, the adjacent valve will decelerate and disengage from another valve. Then, the second cylinder 332 is driven to release the restriction on the adjacent valve. In this way, only one valve is transported in the width direction of the flow channel 32.
[0041] In addition, when two valves in the flow channel 32 are too close together along the transport direction, 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 briefly limit the valve behind, so that a safe distance is left between it and the valve in front, and then releases the limit on the valve.
[0042] As an optional embodiment, a gap is provided between the lower sides of the diverter plates 2, and the gap communicates with the chamber. The gap can serve as a dust removal function. When the valve slides onto the conveyor belt assembly 31 via the diverter plates 2, the dust left on the diverter plates 2 can fall into the chamber through the gap for collection, reducing the amount of dust falling onto the conveyor belt assembly 31. It should be noted that the size of the gap is set according to the actual situation, preferably without affecting the maximum size of the valve sliding onto the conveyor belt assembly 31.
[0043] Furthermore, as shown in the figure, the foolproof component 4 is used to receive valves output from the three flow channels 32 respectively and detect the weight of the valves. When the detected weight is equal to the weight of one valve, the foolproof component 4 removes the valve; when the detected weight is greater than the weight of one valve, the foolproof component 4 stops operating. This ensures that the pressure detection component 5 performs pressure testing on only one valve at a time, which helps improve the reliability of the test results.
[0044] Specifically, the foolproof component 4 includes a support plate 41 and three sets of pressure transfer components 42. One end of the support plate 41 is positioned near the other end of the conveyor belt assembly 31, and the top of the support plate 41 is fixedly connected to the bottom of the first partition 34 to the fourth partition 37. Three through holes 411 are provided on the side of the support plate 41 near the conveyor belt assembly 31, and each of the three through holes 411 corresponds to one of the three flow channels 32 and the three pressure detection components 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 base 427, and a motor 428. The lifting plate 421 is vertically slidably connected within the corresponding through hole 411. It should be noted that the initial state of the lifting plate 421 can be located within the corresponding through hole 411, so that after the valve is conveyed by the conveyor belt assembly 31, it can slide directly horizontally onto the lifting plate 421, which is beneficial for protecting the valve. The two mounting plates 422 are symmetrically fixedly connected to the bottom of the lifting plate 421. Both ends of the rotating shaft 423 are fixedly connected to the two mounting plates 422 respectively. 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 seat 424 is rotatably connected to the rotating shaft 423, and the two ends of the base 427 are fixedly connected to the side wall of the connecting seat 424 and the motor 428, respectively. The fixed end of the third cylinder 426 is fixedly connected to the base plate 13, and the upper and lower connecting ends of the pressure sensor 425 are fixedly connected to the telescopic end of the third cylinder 426 and the bottom of the connecting seat 424, respectively.
[0046] In operation, when the 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 a single valve, the pressure sensor 425 transmits the information to the controller 9. The controller 9 then controls the third cylinder 426 to extend and retract downwards. The lifting plate 421 then lowers the corresponding valve. When the valve reaches a preset height, the third cylinder 426 stops, and the motor 428 starts. The motor 428, through the transmission between the shaft 423 and the mounting plate 422, drives the lifting plate 421 to rotate, thereby unloading the valve from the corresponding lifting plate 421. It should be noted that during the operation of the foolproof component 4, the operation of the conveyor belt assembly 31 can be paused to prevent the next valve from falling directly into the through hole 411 during operation. Furthermore, the valve can be unloaded towards 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 that of the valve, which allows the valve to slide more accurately onto the lifting plate 421.
[0048] As an optional embodiment, such as Figure 1 As shown, three alarms 8 can be installed on the support plate 41. The three alarms 8 correspond one-to-one with 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, thereby improving safety.
[0049] In addition, such as Figure 1 , Figure 3 and Figure 5 As shown, the pressure detection component 5 is provided in three sets. The pressure detection component 5 is installed on the housing 1 and corresponds to the three flow channels 32. It is used to perform pressure detection on the valves that are removed 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. The side of the load-bearing plate 52 closest to the lifting plate 421 is rotatably connected to the mounting base 51, and the rotation axis 423 of the load-bearing plate 52 can be in the same direction as the width of the flow channel 32. The fixed end of the first hydraulic cylinder 53 is fixedly connected to the base plate 13, and the telescopic end of the first hydraulic cylinder 53 is 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 unloaded via the lifting plate 421, it falls onto the load-bearing plate 52. At this point, the second hydraulic cylinder 54 is activated, which drives the pressure plate 55 to apply pressure to the valve and test its compressive strength. After the test is completed, the second hydraulic cylinder 54 is activated to lift the pressure plate 55 and disengage it from the valve, and the first hydraulic cylinder 53 is activated to lower its telescopic end. At this time, the load-bearing plate 52 will rotate, thereby unloading the tested valve. It should be noted that the telescopic lengths of the first hydraulic cylinder 53 and the second hydraulic cylinder 54 are set according to the specific actual working conditions.
[0052] As an optional embodiment, such as Figure 1 As shown, the automatic valve detection equipment also includes three inclined unloading plates 6. The three unloading plates 6 are fixedly connected to the base plate 13 and correspond one-to-one with three load-bearing plates 52. The higher side of the unloading plate 6 is positioned closer to the load-bearing plate 52 and further away from the lifting plate 421. The unloading plates 6 primarily function to transport the valves. After being unloaded from their corresponding load-bearing plates 52, the valves fall onto the higher side of the unloading plate 6 and slide out along its surface, thus providing better protection for the valves. Furthermore, the unloading direction of the unloading plates 6 can be set according to actual working conditions, facilitating the subsequent collection of the valves.
[0053] Furthermore, as shown in the figure, two limiting plates 7 are symmetrically fixedly connected to both sides of the main flow plate 21 along the transmission direction. The limiting plates 7 are positioned close to the conveyor belt assembly 31. The limiting plates 7 mainly serve to limit movement. By positioning the limiting plates 7 close to the conveyor belt assembly 31, since there is invalid space between the first partition 34 and the second partition 35 of the valve, and between the second partition 35 and the third partition 36 and the fourth partition 37, the design of the limiting plates 7 is to prevent the valve from falling onto the transition plate 23 when it approaches the conveyor belt assembly 31, and thus falling into the invalid space. This ensures that the valve eventually falls into the three flow channels 32.
[0054] In addition, as shown in the figure, the automatic valve detection equipment also includes a limiting rod 30. The axis of the limiting rod 30 is set perpendicular to the transport direction of the conveyor belt assembly 31, that is, it is the same as the width direction of the flow channel 32. The limiting 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 limiting 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 limiting rod 30 mainly serves to limit the movement of valves. When multiple valves are stacked vertically, the limiting rod 30 can block the valves above, thereby facilitating the interval transmission of valves within the flow channel 32.
[0055] It should be noted that the actuators, including the first cylinder 331, the second cylinder 332, the image sensor 334, the conveyor belt assembly 31, the vibrator 20, the motor 428, the third cylinder 426, the first hydraulic cylinder 53, the second hydraulic cylinder 54, and the alarm 8, are all electrically connected to the controller 9. This facilitates the controller 9 in receiving information and sending commands.
[0056] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
