Description

Technical Field

[0001] The invention relates to the technical field of charging devices, and in particular to an automatic positioning nitrogen charging device for a liquid storage device and an air-conditioning compressor. Background Art

[0002] As a key component in the refrigeration system, the accumulator is located on the compressor body and is mainly used to store refrigerant. Its role is not only to store refrigerant, but also plays a vital role in the stability and efficiency of the refrigeration system. Specifically, the accumulator can balance the pressure of the condenser, prevent excessive accumulation of gas in the condenser, and keep the system in a relatively stable operating state, thereby avoiding the refrigeration effect affected by unstable pressure. In the refrigeration system, the phenomenon of liquid entering the compressor and instantly vaporizing can seriously damage the compressor and even cause system failure. The accumulator effectively prevents gas or liquid mixture from entering the low-pressure compressor by ensuring that the refrigerant flows into the compressor at a suitable pressure and state. The accumulator can effectively prevent excessive accumulation of condensate in the condenser and excessive accumulation of refrigerant in the condenser, thereby improving the overall heat exchange efficiency of the refrigeration system. Therefore, the accumulator is crucial to the stable operation and efficient heat transfer of the entire refrigeration system. The accumulator needs to be welded to the compressor body to ensure that the refrigerant can flow efficiently in the pipeline. However, the welding quality between the accumulator and the compressor body directly affects the performance of the entire system, especially the stability of the pipeline. However, loose welding or inaccurate positioning can cause the pipeline to vibrate during operation, affecting the stability of the entire system. Cracks or leaks in the welding parts can cause refrigerant leakage, directly affecting the refrigeration efficiency and even causing adverse effects on the environment. Poor welding may cause irregular airflow and pressure fluctuations in the working environment of the compressor, thereby generating unnecessary noise and affecting the user experience. The existence of these problems not only reduces the overall performance of the refrigeration system, but may also cause system failures, thus affecting the service life of the air-conditioning equipment and user satisfaction.

[0003] It can be seen that ensuring that the quality, positioning accuracy, welding method and welding parameters of the liquid receiver and the compressor body meet the strict process requirements is the key to improving the stability of the refrigeration system and reducing the occurrence of failures. At present, most of the welding processes of liquid receivers rely on manual operation, which brings problems such as low welding efficiency, high risk of welding leaks, and inaccurate positioning in production, which in turn affects 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 operating errors, and improve the overall quality control level of the production line. Summary of the invention

[0037] The liquid accumulator 20 plays a key role in the refrigeration system. It is mainly used to store refrigerant and balance the condenser pressure to ensure stable operation of the system. It prevents liquid from entering the compressor and vaporizing instantly, thereby avoiding damage to the compressor. The liquid accumulator 20 also improves the heat exchange efficiency and enhances the overall performance of the refrigeration system. The welding quality between the liquid accumulator 20 and the compressor body directly affects the stability of the system. Poor welding may cause leakage, noise and reduced efficiency. Since the current welding process mostly relies on manual operation, there are problems such as low efficiency and risk of welding leakage, which affects the production quality and stability.

[0038] To this end, an embodiment of the present invention provides a liquid reservoir 20 automatic positioning nitrogen filling device, which can effectively improve welding accuracy and production efficiency, reduce the risk of human operating errors, and improve 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 liquid reservoir 20 and automation of the nitrogen filling process through the cooperation of a positioning component and an automatic nitrogen filling component, thereby reducing errors caused by manual operation. The clamping member 50 in the positioning component accurately clamps the connecting pipe 30 through the clamping claw 51, effectively avoiding errors caused by manual operation and ensuring the position accuracy during welding. The design of the first and second adjustment plates 55 makes the positioning and nitrogen filling process more flexible, can adapt to liquid reservoirs 20 of different specifications, and improves the versatility of the device. The first and second moving components can be precisely adjusted to ensure the accuracy of the positioning component and the nitrogen filling component, thereby improving the overall operating efficiency. The components are connected by fasteners and adjustment holes 433 to ensure the stability of the device and reduce operational errors caused by loose components or deviations. Through automated operation and adjustable structures, the reliance on manual intervention is significantly reduced, reducing the risk of human errors. The combination of automated control and precise positioning helps to maintain consistency in the production process, ensure that each welded part meets high quality standards, and improve the overall quality control level of the production line.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] See also Figure 1 , Figure 1 A schematic diagram of the three-dimensional structure of an automatic positioning and nitrogen charging device for a liquid reservoir 20 provided in an embodiment of the present invention; the automatic positioning and nitrogen charging device for a liquid reservoir 20 comprises a mounting frame 10, a positioning assembly and an automatic nitrogen charging assembly, wherein the positioning assembly and the automatic nitrogen charging assembly are respectively connected to the mounting frame 10, the automatic nitrogen charging assembly is located on one side of the liquid reservoir 20, the positioning assembly is located on the other side of the liquid reservoir 20, and the liquid reservoir 20 is connected to a connecting pipe 30, and the positioning assembly clamps the connecting pipe 30.

[0042] In this embodiment, the mounting frame 10 is installed on the assembly line 60. The mounting frame 10 is installed on the assembly line 60 as a supporting frame of the entire system. The positioning assembly is located on one side of the liquid reservoir 20 and is responsible for clamping and fixing the connecting pipe 30 of the liquid reservoir 20 to ensure that the docking position is accurate. The automatic nitrogen filling assembly is located on the other side of the liquid reservoir 20 and includes an air filling tool 40 driven by an SMC cylinder to realize automatic nitrogen filling.

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

[0044] After the pause, the nitrogen filling tooling of the automatic nitrogen filling assembly begins to move forward until the inflation pipe opening at its front end contacts the inflation port of the liquid reservoir 20. When it is detected that the front resistance cannot continue to move forward, the air valve is automatically opened to achieve automatic nitrogen filling. This process avoids the problems of nitrogen leakage and waste that may occur in traditional manual nitrogen filling. At the same time, the positioning assembly also moves forward until it reaches the position of the connecting pipe 30 at the bottom of the compressor. At this time, the clamp 50 firmly fixes the connecting pipe 30 to prevent any deviation or shaking during the welding process, thereby ensuring the accuracy of the welding position. After completing the welding operation, restart the assembly line 60, all cylinders involved in the work automatically return to the initial position, and close the air valve to prepare for the processing of the next compressor.

[0045] The automatic nitrogen filling assembly and the positioning assembly operate simultaneously to ensure that the liquid reservoir 20 remains stable and motionless during the entire nitrogen filling welding process, thereby improving the quality and efficiency of 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. Accurate positioning and stable support reduce the probability of welding defects and reduce after-sales maintenance costs. Each welding can meet high standards, improve product consistency and reliability, and enhance user satisfaction. The automatic nitrogen filling function reduces the risk of nitrogen leakage and protects the safety and health of operators. Effective use of nitrogen reduces waste and reduces the cost of production materials. The simultaneous cooperation of the automatic nitrogen filling component and the positioning component ensures stability during the welding process and further guarantees welding quality.

[0047] In one embodiment, see Figure 1 The automatic nitrogen filling assembly comprises a first moving assembly and a gas filling tool 40, wherein the first moving assembly is connected to the mounting frame 10, and the gas filling tool 40 is connected to the first moving assembly. Specifically, the gas filling tool 40 is provided with a gas filling nozzle at one end away from the first moving assembly.

[0048] In this example, see Figure 7 In order to prevent the possible damage to the liquid reservoir 20 caused by direct metal contact, the inflating tool 40 is made of a soft and elastic rubber material. This material can not only protect the surface of the liquid reservoir 20 from damage, but also provide a good sealing effect to ensure that there is no leakage during the nitrogen filling process.

[0049] The size of the inflation tool 40 is 70cm*55cm, and this size design has been carefully considered to be compatible with all types of reservoir 20 heads on the market. Regardless of the specific shape or size of the reservoir 20, the inflation tool 40 can ensure a tight fit, achieve sufficient nitrogen filling, and avoid any potential nitrogen leakage problems.

[0050] By designing a universal inflation tool 40 suitable for various types of liquid reservoirs 20, not only is the equipment management on the production line simplified, but the flexibility and adaptability of the system are also enhanced, and it can quickly respond to changes in demand for different products.

[0051] In one embodiment, see Figures 2 to 6 The first moving assembly includes a first base plate 41, a first mounting plate 42, a first adjusting plate 43, an inflatable cylinder 44 and a first connecting member 45. The first base plate 41 is connected to the mounting frame 10, the first mounting plate 42 is connected to the first adjusting plate 43, the inflatable cylinder 44 is connected to the first mounting plate 42, the first connecting member 45 is connected to the inflatable cylinder 44, and the first connecting member 45 is connected to the inflatable tool 40. These components work together to ensure that the inflatable tool 40 can be accurately positioned and can adjust the position according to specific needs.

[0052] In this embodiment, the air cylinder 44, the first connecting member 45 and the air charging tool 40 are key parts of the nitrogen charging device. The air cylinder 44 is a component used to provide power, and drives other components to move through the reciprocating motion of the piston. When the cylinder receives a signal or command, it pushes the first connecting member 45 connected thereto to move forward.

[0053] The first connecting member 45 serves as a bridge between the inflation cylinder 44 and the inflation tooling 40 . It is responsible for transmitting the power from the cylinder to the inflation tooling 40 , ensuring that the tooling can accurately perform the predetermined action.

[0054] The charging tool 40 is a working tool specially designed for charging the liquid reservoir 20 with nitrogen, and usually includes a part that matches the interface of the liquid reservoir 20 to ensure that the nitrogen can be safely and effectively transmitted to the interior of the liquid reservoir 20.

[0055] The nitrogen filling hose and the gas valve are components located inside the gas filling tool 40. The nitrogen filling hose is used to conduct nitrogen, and the gas valve controls the opening and closing of the nitrogen flow. Depending on the working state, the gas valve will be opened or closed under specific conditions.

[0056] When the charging cylinder 44 drives the entire system to move forward, it means that the charging tool 40 is approaching the liquid reservoir 20 to prepare for the nitrogen charging operation, and when the charging port of the charging tool 40 is docked with the liquid reservoir 20, the internal mechanism will trigger the valve to open, allowing nitrogen to flow to the liquid reservoir 20 through the nitrogen charging hose. After the nitrogen charging is completed, as the charging cylinder 44 drives all related components back to the starting position (i.e., returning to the original position), this action will trigger the valve to close, stop the nitrogen supply, and maintain the nitrogen pressure in the liquid reservoir 20.

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

[0058] In one embodiment, see Figures 2 to 6 The first adjustment plate 43 includes a first vertical plate 431 and a first horizontal plate 432 , the first horizontal plate 432 is connected to the first substrate 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, see 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 via fasteners.

[0060] The first substrate 41, the first mounting plate 42, the inflatable cylinder 44 and the first connecting member 45 are made of aluminum profiles and acrylic plates; the first adjusting plate 43 uses 12*M8 through holes, and the height of the inflatable tooling 40 can be adjusted by the first adjusting plate 43 according to the installation position of the liquid reservoir 20.

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

[0062] The first adjustment plate 43 is composed 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 inflatable tooling 40 to be fine-tuned through the first adjustment plate 43 to meet the needs of different models of liquid reservoirs 20.

[0063] The inflatable 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 inflatable cylinder 44, but also docked with the inflatable tooling 40, so as to achieve position adjustment and operation control of the inflatable tooling 40.

[0064] In order to facilitate height adjustment, a plurality of adjustment holes 433 are provided on the first vertical plate 431, and these holes enable the first mounting plate 42 to be connected thereto by fasteners (such as screws), thereby changing the relative height. The advantage of such a design is that the user can flexibly adjust the height of the inflation tooling 40 according to the actual installation position of the liquid reservoir 20, ensuring that the nitrogen charging task can be completed accurately every time.

[0065] In terms of material selection, considering the requirements of lightness and strength, the first substrate 41, the first mounting plate 42, the inflatable cylinder 44 and the first connecting member 45 are all made of a combination of aluminum profiles and acrylic plates. The aluminum profile has good mechanical properties and corrosion resistance, while the acrylic plate increases the beauty 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 connecting member 45 is cylindrical and the other end is square. The square is connected to the inflation cylinder 44. A through hole is provided in the cylinder for inserting one end of the inflation tooling 40 therein and then reinforced with fasteners.

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

[0068] In one embodiment, see Figure 1 as well as Figure 8 The above-mentioned positioning assembly includes a clamping member 50 and a second movable assembly. The second movable assembly is connected to the clamping member 50. The clamping member 50 fixes the connecting pipe 30. The second movable assembly is connected to the mounting frame 10.

[0069] The clamping member 50 is made of hard nylon to avoid collision with metal, and the size of 35cm*59cm can meet the model requirements of clamping all liquid storage tank connecting pipes 30.

[0070] In one embodiment, see Figure 8 The clamping member 50 includes two clamping jaws 51 and a connecting block 52. The two clamping jaws 51 are connected to one end of the connecting block 52. A clamping space for the connecting pipe 30 to be placed is formed between the two clamping jaws 51. The connecting block 52 is connected to the second moving assembly. The clamping space is used to accommodate and fix the connecting pipe 30. This design ensures that the connecting pipe 30 can be firmly clamped and allows for quick loading and unloading as needed.

[0071] In one embodiment, see Figure 1 as well as Figures 9 to 11 The second moving assembly includes a second base plate 53, a second mounting plate 54, a second adjustment plate 55, a power source 56 and a second connecting member 57. The second base plate 53 is connected to the mounting frame 10, the second mounting plate 54 is connected to the second adjustment plate 55; 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 are not described here. The first base plate 41 and the second base plate 53 are both L-shaped structures.

[0072] The second base plate 53 is directly fixed on the mounting frame 10 to provide support for the entire assembly; the second mounting plate 54 is connected to the second base plate 53 through the second adjustment plate 55 to form an adjustable mechanical frame. The second connecting plate includes a transverse connecting plate and a vertical connecting plate, wherein the transverse connecting plate is connected to a side of the vertical connecting plate close to the clamping member 50, the transverse 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, see Figure 1 as well as Fig. 9 , Fig.12 The second adjustment plate 55 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 adjustment plate 55 is consistent with that of the first adjustment plate 43.

[0074] The second adjustment plate 55 is also composed of a second vertical plate and a second horizontal plate, and its structure is consistent with the first adjustment plate 43, that is, the second horizontal plate is connected to the second base plate 53, and the second vertical plate is located on one side and connected to the second mounting plate 54. Such a design allows the height or angle to be changed by adjusting the hole position on the second vertical plate, thereby meeting the needs of different application scenarios.

[0075] The above-mentioned device cleverly combines the positioning component with the automatic nitrogen filling component through the integrated mounting frame 10, ensuring the coordinated operation of the entire system and laying a solid foundation for improving welding accuracy and production efficiency. The positioning component accurately clamps the connecting pipe 30 to ensure that the liquid reservoir 20 maintains a fixed position during the welding process, effectively avoiding welding quality problems caused by position offset, thereby improving the consistency and accuracy of welding. The automatic nitrogen filling component is located on one side of the liquid reservoir 20, and can inject inert gas nitrogen into the liquid reservoir 20 before welding to prevent metal oxidation during welding, ensure the quality of the weld, reduce the rework rate, and improve the qualified rate of the product. The use of automated equipment to replace the traditional manual operation method greatly reduces the impact of human factors on the welding process, reduces product defects caused by operational errors, and further ensures the stability of product quality. The device is compact and reasonable in design, and the coordination between the various components is tight and orderly, which not only improves the space utilization rate, but also makes the production line layout more optimized, helps to realize the assembly line 60 operation, and speeds up the production rhythm. Equipped with an intelligent control system, it can monitor and adjust the working status of the positioning component and the automatic nitrogen filling component in real time, ensuring that each operation can achieve the expected effect, and enhancing the controllability and flexibility of production. The system has good scalability and compatibility, and can easily adapt to different specifications and models of liquid storage tanks 20 and their connecting pipes 30, meet diverse production needs, expand the scope of application, and improve the return on investment of the equipment. The overall solution effectively integrates the positioning, nitrogen filling and welding processes, realizes seamless connection of the process, significantly improves the overall quality control level of the production line, and brings significant competitive advantages to manufacturing companies.

[0076] The above-mentioned automatic positioning and nitrogen filling device for the liquid reservoir 20 integrates the positioning component and the automatic nitrogen filling component through the mounting frame 10, ensuring that the liquid reservoir 20 maintains a precise position during the welding process, thereby significantly improving the welding accuracy and speeding up the production rhythm; the positioning component accurately clamps the connecting pipe 30 of the liquid reservoir 20 to stabilize its position and prevent displacement during welding, effectively reducing quality problems caused by inaccurate positioning and improving the product qualification rate; the automatic nitrogen filling component injects nitrogen into the liquid reservoir 20 before welding to avoid metal oxidation and ensure excellent weld quality, while simplifying the operating process and improving work efficiency; the use of automation technology instead of manual operation greatly reduces the risk of human error, 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.
