Description

Technical Field

[0001] This utility model relates to the field of inflation device technology, and in particular to an automatic positioning nitrogen filling device for a liquid reservoir and an air conditioning compressor. Background Technology

[0002] The receiver-drier, a key component in a refrigeration system, is located on the compressor and primarily stores refrigerant. Its role extends beyond refrigerant storage; it plays a crucial role in the stability and efficiency of the refrigeration system. Specifically, the receiver-drier balances condenser pressure, preventing excessive gas buildup within the condenser and maintaining a relatively stable operating state, thus avoiding pressure instability that could negatively impact refrigeration performance. In a refrigeration system, the instantaneous vaporization of liquid entering the compressor can severely damage it and even lead to system failure. By ensuring refrigerant flows into the compressor at the appropriate pressure and condition, the receiver-drier effectively prevents gas or liquid mixtures from entering the low-pressure compressor. It also effectively prevents excessive condensate buildup in the condenser, thus improving the overall heat exchange efficiency of the refrigeration system. Therefore, the receiver-drier is essential for the stable operation and efficient heat transfer of the entire refrigeration system. The receiver-drier needs to be welded to the compressor body to ensure efficient refrigerant flow in the piping. However, the quality of the weld between the receiver-drier and the compressor body directly affects the performance of the entire system, especially the stability of the piping. However, weak welds or inaccurate positioning can cause pipeline vibrations during operation, affecting the stability of the entire system. Cracks or leaks in the welds can lead to refrigerant leaks, directly impacting cooling efficiency and potentially causing adverse environmental effects. Poor welding can also cause irregular airflow and pressure fluctuations in the compressor's operating environment, generating unnecessary noise and affecting user experience. These problems not only reduce the overall performance of the refrigeration system but can also cause system malfunctions, thus affecting the lifespan of the air conditioning equipment and user satisfaction.

[0003] Therefore, ensuring that the quality, positioning accuracy, welding methods, and welding parameters of the weld between the receiver and the compressor body meet strict process requirements is crucial for improving the stability of the refrigeration system and reducing malfunctions. Currently, the welding process for receivers mostly relies on manual operation, which leads to problems such as low welding efficiency, high risk of incomplete welds, and inaccurate positioning, thus affecting production efficiency and quality stability.

[0004] Therefore, it is necessary to design a new device to effectively improve welding accuracy and production efficiency, reduce the risk of human error, and enhance the overall quality control level of the production line. Utility Model Content

[0037] The receiver 20 plays a crucial role in the refrigeration system, primarily storing refrigerant and balancing condenser pressure to ensure stable system operation. It prevents liquid from entering the compressor and instantly vaporizing, thus avoiding compressor damage. The receiver 20 also improves heat exchange efficiency, enhancing the overall performance of the refrigeration system. The welding quality between the receiver 20 and the compressor body directly affects system stability; poor welding can lead to leaks, noise, and reduced efficiency. Because current welding processes largely rely on manual operation, they suffer from low efficiency and the risk of incomplete welds, impacting production quality and stability.

[0038] Therefore, this utility model provides an automatic positioning nitrogen filling device for a liquid reservoir 20, which effectively improves welding accuracy and production efficiency, reduces the risk of human error, and enhances the overall quality control level of the production line.

[0039] Specifically, an automatic positioning and nitrogen filling device for a liquid reservoir 20 ensures accurate positioning of the reservoir 20 and automates the nitrogen filling process through the cooperation of a positioning component and an automatic nitrogen filling component, reducing errors caused by manual operation. The clamping component 50 in the positioning component precisely clamps the connecting pipe 30 through grippers 51, effectively avoiding errors caused by manual operation and ensuring positional accuracy during welding. The design of the first and second adjusting plates 55 makes the positioning and nitrogen filling process more flexible, adaptable to different specifications of the reservoir 20, and improving the device's versatility. The first and second moving components can be precisely adjusted to ensure the accuracy of the positioning and nitrogen filling components, thereby improving overall work efficiency. All components are connected by fasteners and adjusting holes 433, ensuring the stability of the device and reducing operational errors caused by loose or misaligned components. Through automated operation and an adjustable structure, reliance on manual intervention is significantly reduced, lowering the risk of human error. The combination of automated control and precise positioning helps maintain consistency in the production process, ensuring that each welded part meets high-quality standards and improving the overall quality control level of the production line.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of an automatic positioning and nitrogen filling device for a liquid reservoir 20 provided in an embodiment of the present utility model. The automatic positioning and nitrogen filling device for a liquid reservoir 20 includes a mounting frame 10, a positioning component, and an automatic nitrogen filling component. The positioning component and the automatic nitrogen filling component are respectively connected to the mounting frame 10. The automatic nitrogen filling component is located on one side of the liquid reservoir 20, and the positioning component is located on the other side of the liquid reservoir 20. The liquid reservoir 20 is connected to a connecting pipe 30, and the positioning component clamps the connecting pipe 30.

[0042] In this embodiment, the mounting bracket 10 is installed on the production line 60. The mounting bracket 10 serves as the support frame for the entire system and is installed on the production line 60. The positioning component is located on one side of the reservoir 20 and is responsible for clamping and fixing the connecting pipe 30 of the reservoir 20 to ensure accurate docking. The automatic nitrogen filling component is located on the other side of the reservoir 20 and includes a filling fixture 40 driven by an SMC cylinder, enabling automated nitrogen filling.

[0043] Specifically, when the compressor flows along production line 60 past the designated position of the welding fixture, production line 60 is paused. This step ensures that the compressor stops at a fixed point so that subsequent automated equipment can perform precise operations.

[0044] After a pause, the nitrogen-filling fixture of the automatic nitrogen-filling assembly begins to move forward until its front gas filling port contacts the gas filling port of the reservoir 20. When resistance is detected and further progress is impossible, the gas valve automatically opens, achieving automatic nitrogen filling. This process avoids the nitrogen leakage and waste problems that may occur in traditional manual nitrogen filling. Simultaneously, the positioning assembly also moves forward until it reaches the position of the connecting pipe 30 at the bottom of the compressor. At this point, the clamping component 50 firmly fixes the connecting pipe 30, preventing any displacement or shaking during welding, thus ensuring the accuracy of the welding position. After the welding operation is completed, the production line 60 is restarted, and all participating cylinders automatically return to their initial positions and close their gas valves, preparing for the next compressor's processing.

[0045] The automatic nitrogen filling component and the positioning component operate simultaneously to ensure that the reservoir 20 remains stable throughout the nitrogen-filled welding process, thereby improving the quality and efficiency of the welding.

[0046] By replacing manual operation with an automated control system, the time required for each welding cycle is significantly shortened, improving the overall efficiency of the production line. Precise positioning and stable support reduce the probability of welding defects and lower after-sales maintenance costs. High standards are achieved in every weld, improving product consistency and reliability, and enhancing user satisfaction. The automatic nitrogen filling function reduces the risk of nitrogen leakage, protecting the safety and health of operators. Effective use of nitrogen reduces waste and lowers the cost of production materials. The simultaneous operation of the automatic nitrogen filling component and the positioning component ensures stability during the welding process, further guaranteeing welding quality.

[0047] In one embodiment, please refer to Figure 1 The aforementioned automatic nitrogen filling assembly includes a first moving component and an inflation fixture 40. The first moving component is connected to the mounting bracket 10, and the inflation fixture 40 is connected to the first moving component. Specifically, the inflation fixture 40 has an inflation port at its end furthest from the first moving component.

[0048] In this embodiment, please refer to Figure 7 To prevent potential damage to the reservoir 20 from direct metal contact, the inflation fixture 40 is made of a soft and elastic rubber material. This material not only protects the surface of the reservoir 20 from damage but also provides a good seal, ensuring no leakage during nitrogen filling.

[0049] The inflation fixture 40 measures 70cm x 55cm, a size carefully designed to be compatible with all models of reservoir heads 20 available on the market. Regardless of the specific shape or size of the reservoir 20, the inflation fixture 40 ensures a tight fit for full nitrogen filling while preventing any potential nitrogen leakage issues.

[0050] By designing a universal inflation fixture 40 suitable for various models of liquid reservoirs 20, not only is equipment management on the production line simplified, but the system's flexibility and adaptability are also enhanced, enabling rapid response to changes in the needs of different products.

[0051] In one embodiment, please refer to Figures 2 to 6 The aforementioned first moving component includes a first base plate 41, a first mounting plate 42, a first adjusting plate 43, an inflation cylinder 44, and a first connecting member 45. The first base plate 41 is connected to the mounting frame 10, and the first mounting plate 42 is connected to the first adjusting plate 43. The inflation cylinder 44 is connected to the first mounting plate 42, and the first connecting member 45 is connected to both the inflation cylinder 44 and the inflation fixture 40. These components work together to ensure that the inflation fixture 40 can be accurately positioned and its position can be adjusted according to specific needs.

[0052] In this embodiment, the inflation cylinder 44, the first connecting member 45, and the inflation fixture 40 are key components of the nitrogen filling device. The inflation cylinder 44 is a power-providing component that drives other parts to move through the reciprocating motion of a piston. When the cylinder receives a signal or command, it pushes the first connecting member 45 connected to it to move forward.

[0053] The first connector 45 acts as a bridge between the inflation cylinder 44 and the inflation fixture 40. It is responsible for transmitting power from the cylinder to the inflation fixture 40, ensuring that the fixture can accurately perform the predetermined actions.

[0054] The nitrogen filling fixture 40 is a working tool specifically designed to perform nitrogen filling operations on the reservoir 20. It typically includes parts that match the interface of the reservoir 20 to ensure that nitrogen can be safely and effectively transferred into the reservoir 20.

[0055] The nitrogen filling hose and valve are components located inside the filling fixture 40. The nitrogen filling hose is used to conduct nitrogen gas, while the valve controls the opening and closing of the nitrogen flow. Depending on the operating conditions, the valve will open or close under specific conditions.

[0056] When the inflation cylinder 44 drives the entire system forward, it means that the inflation fixture 40 is approaching the reservoir 20 in preparation for nitrogen filling, when the inflation port of the inflation fixture 40 aligns with the reservoir 20. At this point, an internal mechanism triggers the gas valve to open, allowing nitrogen to flow through the nitrogen filling hose to the reservoir 20. After nitrogen filling is complete, as the inflation cylinder 44 moves all relevant components back to their starting position (i.e., back to their original position), this action triggers the gas valve to close, stopping the nitrogen supply and maintaining the nitrogen pressure within the reservoir 20.

[0057] This design ensures the safety and efficiency of the nitrogen filling process, while also reducing the need for human intervention and lowering the possibility of human error.

[0058] In one embodiment, please refer to Figures 2 to 6 The first adjustment plate 43 mentioned above includes a first vertical plate 431 and a first horizontal plate 432. The first horizontal plate 432 is connected to the first base plate 41. One side of the first horizontal plate 432 is connected to the first vertical plate 431, and the first vertical plate 431 is connected to the first mounting plate 42.

[0059] In one embodiment, please refer to Figures 2 to 6 The first vertical plate 431 is provided with a plurality of adjustment holes 433, and the first mounting plate 42 is connected to the adjustment holes 433 by fasteners.

[0060] The first base plate 41, the first mounting plate 42, the inflation cylinder 44 and the first connector 45 are made of aluminum profile and acrylic plate; the first adjustment plate 43 has 12*M8 through holes, and the height of the inflation fixture 40 can be adjusted by the first adjustment plate 43 according to the installation position of the liquid reservoir 20.

[0061] In this embodiment, the first substrate 41 serves as the base of the entire first moving assembly and is directly fixed to the mounting bracket 10, providing a stable support platform for other components.

[0062] The first adjusting plate 43 consists of a first vertical plate 431 and a first horizontal plate 432, wherein the first horizontal plate 432 is connected to the first base plate 41, and the first vertical plate 431 is vertically mounted on one side of the first horizontal plate 432 and connected to the first mounting plate 42. This layout allows the height of the inflation fixture 40 to be finely adjusted via the first adjusting plate 43 to accommodate the needs of different models of liquid reservoirs 20.

[0063] The inflation cylinder 44 is fixed on the first mounting plate 42 and is responsible for providing power to push the first connecting member 45 forward or backward. The first connecting member 45 is not only connected to the inflation cylinder 44, but also docks with the inflation fixture 40, thereby realizing the position adjustment and operation control of the inflation fixture 40.

[0064] To facilitate height adjustment, the first vertical plate 431 is provided with several adjustment holes 433. These holes allow the first mounting plate 42 to be connected to it via fasteners (such as screws), thereby changing the relative height. The advantage of this design is that users can flexibly adjust the height of the inflation fixture 40 according to the actual installation position of the liquid reservoir 20, ensuring that the nitrogen filling task can be completed accurately every time.

[0065] In terms of material selection, considering the requirements of lightweighting and strength, the first substrate 41, the first mounting plate 42, the inflation cylinder 44, and the first connector 45 are all made of a combination of aluminum profiles and acrylic sheets. Aluminum profiles have good mechanical properties and corrosion resistance, while acrylic sheets increase the aesthetics and transparency of the overall structure, making it easier to observe the internal operation.

[0066] It is particularly noteworthy that one end of the first connector 45 is cylindrical and the other end is square. The square end is connected to the inflation cylinder 44. The cylindrical end has a through hole, which is for inserting one end of the inflation fixture 40 into it and then reinforcing it with fasteners.

[0067] The first adjustment plate 43 is specially designed with 12*M8 through holes. This specification is chosen to better match the standard tight inflation on the market, and also to facilitate quick disassembly or adjustment as needed.

[0068] In one embodiment, please refer to Figure 1 as well as Figure 8 The aforementioned positioning components include a clamping member 50 and a second moving component. The second moving component is connected to the clamping member 50, the clamping member 50 is fixedly connected to the connecting tube 30, and the second moving component is connected to the mounting bracket 10.

[0069] The aforementioned clamping component 50 is made of hard nylon to avoid damage from metal. Its 35cm*59cm size can meet the model requirements for clamping all liquid storage tank connecting pipes 30.

[0070] In one embodiment, please refer to Figure 8 The aforementioned clamping member 50 includes two grippers 51 and a connecting block 52. The two grippers 51 are connected to one end of the connecting block 52, forming a clamping space between the two grippers 51 for placing the connecting tube 30. The connecting block 52 is connected to the second moving component. The clamping space is used to accommodate and fix the connecting tube 30. This design ensures that the connecting tube 30 can be firmly clamped while allowing for quick loading and unloading as needed.

[0071] In one embodiment, please refer to Figure 1 as well as Figures 9 to 11 The aforementioned second moving component includes a second base plate 53, a second mounting plate 54, a second adjusting plate 55, a power source 56, and a second connecting member 57.

The power source 56 is connected to the second mounting plate 54, the second connecting member 57 is connected to the power source 56, and the second connecting member 57 is connected to the connecting block 52. The structures of the second base plate 53 and the second mounting plate 54 correspond to those of the first base plate 41 and the first mounting plate 42, and will not be described in detail here. Both the first base plate 41 and the second base plate 53 have an L-shaped structure.

[0072] The second base plate 53 is directly fixed to the mounting bracket 10, providing support for the entire assembly; while the second mounting plate 54 is connected to the second base plate 53 through the second adjusting plate 55, forming an adjustable mechanical frame. The second connecting plate includes a horizontal connecting plate and a vertical connecting plate, wherein the horizontal connecting plate is connected to the side of the vertical connecting plate near the clamping member 50, the horizontal connecting plate is connected to the clamping member 50, and the vertical connecting plate is connected to the power source 56.

[0073] In one embodiment, please refer to Figure 1 as well as Figure 9 , Figure 12 The second adjusting plate 55 mentioned above includes a second vertical plate and a second horizontal plate. The second horizontal plate is connected to the second base plate 53. One side of the second horizontal plate is connected to the second vertical plate, and the second vertical plate is connected to the second mounting plate 54. The structure of the second adjusting plate 55 is the same as that of the first adjusting plate 43.

[0074] The second adjusting plate 55 also consists of a second vertical plate and a second horizontal plate, with the same structure as the first adjusting plate 43. Specifically, the second horizontal plate is connected to the second base plate 53, while the second vertical plate is located on one side and connected to the second mounting plate 54. This design allows the height or angle to be changed by adjusting the holes on the second vertical plate, thus meeting the needs of different application scenarios.

[0075] The aforementioned device cleverly integrates the positioning component and the automatic nitrogen filling component through the integrated mounting bracket 10, ensuring the coordinated operation of the entire system and laying a solid foundation for improving welding accuracy and production efficiency.

[0076] The aforementioned automatic positioning and nitrogen filling device for a liquid reservoir 20 integrates a positioning component and an automatic nitrogen filling component through a mounting bracket 10. This ensures that the liquid reservoir 20 maintains a precise position during welding, thereby significantly improving welding accuracy and accelerating production.

It also simplifies the operation process and improves work efficiency. By using automation technology to replace manual operation, the risk of human error is greatly reduced, making the entire welding process more stable and reliable, enhancing the quality control capability of the production line, and improving the overall quality control level of the production line.
