Description

Technical Field

[0001] This utility model relates to the field of capping machine technology, and specifically discloses a hydraulic cap sealing device for thermal management of new energy vehicles. Background Technology

[0002] The hydraulic cap sealing device for thermal management of new energy vehicles is a key piece of equipment integrated into the coolant tank packaging production line. The coolant it processes is mainly used for precise temperature control of core components such as batteries, motors, and electronic controls in new energy vehicles, directly affecting the safety and performance of the entire vehicle. Its basic workflow is as follows: Plastic barrels containing coolant are transported to the capping station by a horizontal conveyor belt. Above the capping station, there is an inclined capping conveyor belt that works in conjunction with the horizontal conveyor belt. When the plastic barrel enters this area, the cap, which has been manually or mechanically placed at the barrel opening, first contacts the inlet end of the capping conveyor belt above. As the barrel continues to move horizontally, the cap, guided by the inclined capping conveyor belt, is subjected to a gradually increasing vertical downward pressure from initial contact to final compression, thus being smoothly pressed into the barrel opening to complete the seal. During this process, the lateral extrusion mechanisms located on both sides of the plastic barrel simultaneously apply progressive radial pressure to the barrel, aiming to expel excess air from the barrel and prevent abnormal internal pressure after sealing, thereby ensuring the reliability of the packaging quality.

[0003] In the automated packaging process of coolant tanks for new energy vehicles, the cap needs to be pre-placed on the tank opening by manual or automated equipment before sealing. The cap and the coolant tank opening are usually connected by a precise interference fit or snap-fit ​​structure, and are pressed and sealed by vertical downward pressure. The flatness and coaxiality of the initial contact directly determine the quality and reliability of the final cap seal. Under actual production conditions, especially in high-speed, continuously operating automated production lines, due to instantaneous deviations in mechanical positioning, vibrations during the transmission process, or the cap and tank opening themselves, the quality and reliability of the seal may be compromised. The dimensional tolerances that exist may cause the lid to not be placed completely horizontally on the lid opening, resulting in a slight tilt that is not easily detected by the naked eye. If this tilt is not detected, the lid will still perform the pressing action according to the preset stroke after the lid enters the lid pressing station. Because the lid is not in the correct initial position, it will be subjected to uneven circumferential stress during the pressing process, which can easily cause one side to curl up and interfere with the lid opening sealing ring. In severe cases, it may even tear or crush the plastic sealing ring, resulting in sealing failure or product scrap, which directly affects the production yield and schedule. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a hydraulic cover sealing device for thermal management of new energy vehicles, so as to solve the technical problem that the poor initial state such as misalignment before sealing the cover cannot be detected in time, resulting in sealing failure or barrel deformation and other defects during the sealing process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic cap sealing device for thermal management of new energy vehicles, including a conveyor belt, a frame mounted on the conveyor belt, two mounting brackets fixedly connected to the side wall of the frame, a detection mechanism for detecting the placement status of the coolant tank cap between the two mounting brackets, a recycling mechanism for receiving signals from the detection mechanism and removing coolant tanks with unqualified cap placement status from the conveyor belt on the frame, and guide plates for constraining and guiding the coolant tanks on the conveyor belt to move along their preset travel path above the conveyor belt. The detection mechanism includes a pressure sensor with a preset pressure threshold range. The pressure sensor is signal-connected to the recycling mechanism. When the detection value of the pressure sensor deviates from the pressure threshold range, it sends a control signal to the recycling mechanism.

[0006] In this solution, the inspection mechanism can accurately and in real time sense the placement posture of the lid before the capping process begins, especially subtle tilting changes. The pressure sensor has a preset pressure threshold range, converting physical contact signals into precise electrical criteria to effectively distinguish between normal and abnormal states. It is highly sensitive and stable. Once an unqualified lid posture is detected, the pressure sensor transmits the signal to the recycling mechanism, which automatically and quickly removes the defective product from the production line, effectively preventing the subsequent flow of defective products. Compared with existing devices that lack pre-detection capabilities and can only detect problems after capping or even later, this device avoids secondary quality defects such as edge warping and thread damage caused by lid tilting, significantly reducing the product scrap rate. At the same time, the fully automated inspection and rejection process greatly improves production efficiency and overall yield, demonstrating a high degree of intelligence and reliability.

[0007] Furthermore, the detection mechanism also includes a mounting plate disposed between the two mounting brackets. The mounting plate is provided with four auxiliary lifting components. Below the four auxiliary lifting components is a sliding detection component for rolling contact with the lid of the coolant tank placed on top. A fixed cylinder is mounted on the sliding detection component. A slidable round rod is installed inside the fixed cylinder. A spring is provided inside the fixed cylinder. One end of the spring is fixedly connected to the fixed cylinder, and the other end of the spring is fixedly connected to the round rod. The pressure sensor is fixedly connected to the lower part of the mounting plate, and the upper part of the round rod contacts the pressure sensor.

[0008] In this solution, the sliding detection component can achieve smooth rolling contact with the top of the lid, effectively reducing frictional resistance and avoiding scratches on the lid surface. At the same time, it accurately converts changes in the lid's height into vertical displacement. The spring not only provides continuous downward pressure to the rod, ensuring that the rod remains linked with the sliding detection component, its roller, and the guide rod of the auxiliary lifting component below, so that the rod's displacement closely and without lag follows the real-time changes in the lid's height, but also plays a crucial role in buffering and overload protection, preventing damage to the precision pressure sensor due to accidental high-level impacts. The rod then transmits the linear displacement buffered by the spring to the pressure sensor, achieving a stable and accurate conversion from mechanical signal to electrical signal.

[0009] Furthermore, each of the four lifting components includes a guide rod, and a through hole is provided on the mounting plate. One end of the guide rod is fixedly connected to the sliding detection component, and the other end of the guide rod passes through the through hole. A fixing plate with an area larger than the through hole is fixedly connected above the guide rod.

[0010] In this design, one end of the guide rod is fixedly connected to the sliding detection component, while the other end of the guide rod precisely passes through the through hole in the mounting plate. This provides rigid vertical guidance and support for the entire detection component, ensuring that the sliding detection component can smoothly rise and fall along a predetermined path when subjected to the lifting force of the lid. This effectively avoids horizontal swaying and jamming, thus transmitting the height change of the lid accurately and without deviation. The fixed plate has a larger area than the through hole, and its core function is to form a reliable mechanical limiting structure, strictly limiting the sliding stroke of the guide rod within the range of the through hole. This prevents the risk of the guide rod detaching from the mounting plate, ensuring the repeatability of the lifting action and the safety and reliability of the entire mechanism.

[0011] Furthermore, the sliding detection component includes a fixed frame, and multiple rotatable rollers are installed below the fixed frame, all of which can contact the top of the coolant tank lid.

[0012] In this solution, the freely rotating roller can convert the sliding friction during the detection process into rolling friction. When the lid passes through, the roller rotates accordingly, thus smoothly gliding over the lid surface. This not only significantly reduces motion resistance and avoids damage to the lid surface caused by rigid scraping, but also, compared with the detection methods commonly used in existing devices that employ fixed blocks or probes for direct contact, the flexible contact of the roller and the stable support of the fixed frame can sensitively sense the height and tilt of the lid while minimizing the impact and wear caused by contact. This ensures detection accuracy while significantly improving the smoothness of the detection process and the protection of the product.

[0013] Furthermore, the recycling mechanism includes a hydraulic rod, which is disposed on the side wall of the frame. The telescopic end of the hydraulic rod is fixedly connected to a push plate that can contact the coolant tank. Both guide plates are provided with recycling grooves for the push plate to pass through. The conveyor belt is laterally fixedly connected to a collection frame.

[0014] In this solution, a hydraulic rod is used as the power source, which can provide a stable and powerful linear thrust. This ensures that the push plate has sufficient power to quickly push out the considerable weight of the coolant tank. The push plate and the recovery tank on the guide plate are precisely matched to form a discharge channel for the coolant tank. This allows the push plate to fully extend into the coolant tank at the effective push point of the conveyor belt and to return smoothly to its original position. Finally, the defective products that are pushed out are uniformly received by the collection frame fixed to the side of the conveyor belt. This mechanism has a compact structure, direct action, and rapid response. It not only greatly improves the processing efficiency of defective products and eliminates the risk of missed products flowing into subsequent processes, but also significantly reduces labor costs and labor intensity, reflecting a high level of automation and process integration.

[0015] The working principle and beneficial effects of this solution are as follows: When the coolant tank is conveyed into the guide channel formed by the guide plate and arrives below the fixed frame, the top cover of the coolant tank contacts multiple rollers inside the frame. If the cover is placed correctly, it lifts the rollers, and the pressure is transmitted to the sensor through the guide rod, spring and round rod. If the pressure value is within the normal threshold range, the cover continues to be sent to the capping mechanism for sealing. If the cover is tilted, it will cause abnormal lifting height and the pressure will exceed the upper limit of the threshold. The sensor will immediately send a signal, and the hydraulic rod will drive the push plate to push the defective tank into the collection frame through the recycling tank. After manual correction, it will be put back on the line. This device effectively solves the technical problem that the poor initial state of the cover, such as tilting, cannot be detected in time before capping, which leads to sealing failure or tank deformation during the capping process.

[0019] The following detailed description illustrates the specific implementation method: Example

[0020] like Figures 1 to 3 As shown, a hydraulic cover sealing device for thermal management of new energy vehicles is disclosed, including a conveyor belt 1, a frame 2, two guide plates 3, two mounting brackets 4, two support rods 5, a detection mechanism, and a recycling mechanism. The frame 2 is mounted on the conveyor belt 1 and is located on the travel path of the conveyor belt 1. Two guide plates 3 are arranged opposite each other above the conveyor belt 1, and a guide channel is formed between the two guide plates 3 to constrain and guide the coolant tank on the conveyor belt 1 to move linearly along its preset travel path. Two mounting brackets 4 are fixedly connected to the side wall of the frame 2. Two support rods 5 are provided on the side wall of the frame 2. One end of each support rod 5 is fixedly connected to the frame 2, and the other end of each support rod 5 is fixedly connected to the two mounting brackets 4 respectively.

[0021] like Figure 1 As shown, a detection mechanism is set between the two mounting frames 4. The detection mechanism is used to monitor the placement status of the coolant tanks passing on the conveyor belt 1 in real time before the capping process begins, so as to determine whether there are any defects such as missing, offset or crooked caps. A recycling mechanism is set on the frame 2. The recycling mechanism is connected to the detection mechanism by signal. The recycling mechanism is used to receive the signal from the detection mechanism and remove coolant tanks with unqualified cap placement status from the conveyor belt 1.

[0022] like Figure 2As shown, the detection mechanism includes a mounting plate 6, four auxiliary lifting components, a sliding detection component, a fixed cylinder 7, a round rod 8, a spring 9, and a pressure sensor 10. The mounting plate 6 is fixedly connected between two mounting brackets 4. Auxiliary lifting components are symmetrically distributed at the four corners of the mounting plate 6. A sliding detection component is set below the four auxiliary lifting components. The sliding detection component is used to make contact with the lid of the coolant tank when the coolant tank passes by with the conveyor belt 1. The fixed cylinder 7 is installed on the sliding detection component. The round rod 8 is slidably installed in the fixed cylinder 7. The spring 9 is set in the fixed cylinder 7. One end of the spring 9 is fixedly connected to the bottom of the fixed cylinder 7, and the other end of the spring 9 is fixed below the round rod 8. The preload of the spring 9 is set to ensure that the initial force it exerts on the round rod 8 is much less than the weight of the lid. The pressure sensor 10 is installed below the mounting plate 6. The round rod 8 contacts the pressure sensor 10 above. The pressure sensor 10 has a preset normal pressure threshold range. If the detected value deviates from this range, a corresponding control signal will be triggered and sent to the recycling mechanism.

[0023] like Figure 2 As shown, each of the four auxiliary lifting components includes a guide rod 12 and a fixing plate 13. A through hole 11 is provided on the mounting plate 6. A guide rod 12 is provided on the sliding detection component. One end of the guide rod 12 is connected to the sliding detection component, and the other end of the guide rod 12 passes through the through hole 11. A fixing plate 13 is provided at the end of the guide rod 12 away from the sliding detection component. The area of ​​the fixing plate 13 is larger than the area of ​​the through hole 11.

[0024] like Figure 2 As shown, the sliding detection assembly includes a fixed frame 14 and multiple rollers 15. The fixed frame 14 is fixedly connected below the guide rod 12. Multiple rotatable rollers 15 are arranged inside the fixed frame 14. All rollers 15 can contact the top of the barrel lid. The length direction of the rollers 15 is perpendicular to the conveying direction of the conveyor belt 1.

[0025] like Figure 1 As shown, the recycling mechanism includes a support frame 16, a hydraulic rod 17, a push plate 18, and a collection frame 19. The support frame 16 is fixedly connected to the side wall of the frame 2. The hydraulic rod 17 is installed on the support frame 16. A recycling trough 20 is opened on both guide plates 3. The push plate 18 is fixedly connected to the telescopic end of the hydraulic rod 17. The push plate 18 can contact the coolant tank. The collection frame 19 is fixedly connected to the side of the conveyor belt 1.

[0026] In practice When it is necessary to seal the coolant tank with a cap, the cap is first placed manually or automatically on the opening of the coolant tank on the conveyor belt 1. The conveyor belt 1 drives the coolant tank to move forward and gradually enter the guide channel formed by the two guide plates 3. As the conveyor belt 1 continues to run, the coolant tank is transported to the bottom of the fixed frame 14.

[0027] Since multiple freely rotating rollers 15 are installed inside the fixed frame 14, when the coolant tank passes by, the top cover of the tank will roll into contact with the rollers 15. The initial height of the fixed frame 14 is a fixed value. After the cover contacts the rollers 15, it pushes the rollers 15 upward, thereby driving the entire fixed frame 14 to move upward. The fixed frame 14 is connected to the guide rod 12, and the guide rod 12 slides upward in the through hole 11 of the mounting plate 6. The fixed plate 13 on the guide rod 12 limits the guide rod 12 in the through hole 11. The fixed frame 14 simultaneously drives the fixed cylinder 7, spring 9 and round rod 8 to move upward as a whole, so that the upper end of the round rod 8 contacts the pressure sensor 10 below the mounting plate 6 and applies a squeezing force to the pressure sensor 10.

[0028] Since the mounting plate 6 is fixed to the side wall of the frame 2 by the mounting bracket 4, when the round rod 8 squeezes the pressure sensor 10, the spring 9 in the fixed cylinder 7 is compressed, which plays a buffering role and prevents overload damage to the pressure sensor 10. The preload and stiffness of the spring 9 are precisely calculated and selected, and the retraction force it provides is much less than the weight of the lid itself. This ensures that even if the roller 15 contacts the lid and lifts it up during the detection process, the retraction force of the spring 9 will not press the lid, which has been placed on the lid opening, out of place or change its initial position. This ensures the accuracy and non-interference of the detection. While the spring 9 deforms and stores energy, the pressure sensor 10 detects the pressure value in real time. If the lid is placed normally and in the correct position, the pressure measured by the pressure sensor 10 is within the preset normal threshold range. At this time, it is judged as qualified, and no instruction is sent to the hydraulic rod 17. The coolant tank continues to move with the conveyor belt 1 to perform the cap sealing process.

[0029] If the lid is tilted during placement, causing one side to be higher than normal, when the coolant tank passes under the roller 15, the tilted lid will push the roller 15 higher, causing the fixed frame 14 and the round rod 8 to move upward beyond the normal range. This will result in a significant increase in the squeezing force of the round rod 8 on the pressure sensor 10. When the pressure sensor 10 detects that the pressure value exceeds the upper limit of the normal threshold, it will determine that the lid posture is abnormal and then send an electrical signal to the hydraulic rod 17.

[0030] After receiving a signal, the hydraulic rod 17 on the support frame 16 starts to push the push plate 18 towards the collection frame 19 according to the set timing. The push plate 18 extends into the guide channel through the recycling tank 20. At this time, the coolant tank that has completed the test is moved to the corresponding position of the push plate 18 by the conveyor belt 1. The hydraulic rod 17 drives the push plate 18 to push it out laterally, so that the defective product slides into the collection frame 19 through the recycling tank 20 on the guide plate 3. The operator can correct the tilted coolant tank at the collection frame 19 and put it back on the conveyor belt 1. After retesting, the capping and sealing process is carried out.

[0031] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
