Description

A heat exchanger docking device Technical Field

[0001] This utility model belongs to the field of heat exchanger assembly technology, specifically relating to a heat exchanger docking device. Background Technology

[0002] In the current air conditioning manufacturing industry, after the evaporator body and gas-liquid pipes are assembled to form the evaporator, the formed evaporator still needs to undergo a three-in-one process of air leak detection, helium leak detection, and refrigerant charging. However, the prerequisite for air leak detection, helium leak detection, and refrigerant charging is to securely connect the connectors on the gas-liquid pipes to the connectors of external equipment. Currently, this connection is done manually. During connection, a person manually presses down the sliding groove around the connector on the gas-liquid pipe, then the ball bearings inside the connector of the external equipment are locked into the groove at the connector on the gas-liquid pipe. This manual connection method is labor-intensive and inefficient. Manual connection is inconsistent, and the connection quality depends heavily on the operator's skill level. It is repetitive work, causing significant hand strain for employees. Furthermore, it is prone to problems such as damage to the connector pins and insecure connection leading to high-pressure gas leakage that could endanger personnel safety. Summary of the Invention

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0054] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0055] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0056] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0057] Referring to Figures 1-19, according to an embodiment of the present invention, a heat exchanger docking device is provided, comprising: a positioning mechanism 21 and a tube support 119, wherein the positioning mechanism 21 is used to position the main body of the heat exchanger 23, and the tube support 119 is used to position the gas-liquid pipe 232 of the heat exchanger 23.

[0058] The adjustment device further includes a Y-axis adjustment structure, an X-axis adjustment structure, and a Z-axis adjustment structure. The Y-axis adjustment structure is used to adjust the position of the pipe rack 119 in the Y-axis direction, and the X-axis and Z-axis adjustment structures are used to adjust the position of the pipe rack 119 in both the X-axis and Z-axis directions, so that the gas-liquid pipe is aligned with the main body.

[0059] The adjustment device further includes a docking mechanism 31 and a position adjustment mechanism 32. The docking mechanism 31 includes a docking jaw 311, a jaw driving component 312, a docking female head 313, and a female head driving component 314. The position adjustment mechanism 32 can adjust the position of the docking mechanism 31 in the X-axis, Y-axis, and Z-axis directions to align the docking jaw 311 with the gas-liquid pipe 232 of the heat exchanger 23. The jaw driving component 312 is configured to drive the docking jaw 311 to clamp the gas-liquid pipe 331. The free end of the gas-liquid pipe 232 is provided with a connector 332. After the docking jaw 311 clamps the gas-liquid pipe 232, the female head driving component 314 is configured to drive the docking female head 313 to dock with the connector 332.

[0060] In this technical solution, the main body of the heat exchanger is first positioned using the positioning mechanism 21. Then, the position of the gas-liquid pipes is adjusted using the tube rack 119 to ensure accurate alignment between the gas-liquid pipes and the main body. Next, the tube rack 119 is used to position the adjusted gas-liquid pipes. Finally, the main body and gas-liquid pipes are assembled to form the heat exchanger. After the main body and gas-liquid pipes are initially positioned and aligned using the positioning mechanism and tube rack 119, subsequent main bodies and gas-liquid pipes of the same model can be used interchangeably without further adjustment of the positioning mechanism and tube rack 19. Therefore, the entire production process can significantly reduce labor intensity and improve production efficiency. It should be noted that manual positioning methods are subject to fluctuations, and the accuracy of positioning largely depends on the operator's skill level. The positioning device of this application can solve the problem of fluctuations inherent in manual positioning. Through the adjustment device, the position of the tube rack 19 can also be adjusted in the X, Y, and Z axes to meet the positioning requirements of heat exchangers 5 of different specifications and sizes, eliminating the need for manual position adjustment and achieving fully automated assembly.

[0061] First, the position adjustment mechanism 32 adjusts the docking mechanism 1 in the X, Y, and Z axes to ensure accurate alignment of the docking jaws 311 with the gas-liquid pipes of the heat exchanger 23. Then, the jaw drive component 312 drives the docking jaws 311 to clamp the gas-liquid pipes. Finally, the female head drive component 314 drives the docking female head 313 to dock with the connector 332 of the gas-liquid pipes, thus completing the entire docking process. Since the entire docking process is completed automatically by the docking device, it significantly reduces labor intensity and improves docking efficiency compared to existing manual docking methods. Furthermore, manual docking methods suffer from inconsistencies, with accuracy heavily dependent on the operator's skill level. The docking device of this application solves this inconsistency problem. Moreover, manual docking methods are prone to pin damage and unreliable docking, leading to high-pressure gas ejection and posing a safety hazard. The docking device of this application operates completely automatically without human intervention, thus improving personnel safety.

[0062] In some embodiments, the adjustment device further includes a first mounting frame, a second mounting frame 27, and a third mounting frame arranged sequentially. The positioning mechanism 21 and the tube frame 119 are disposed on the second mounting frame 27. The first mounting frame is provided with a Y-axis adjustment structure, and the third mounting frame is provided with a docking mechanism 31, a position adjustment mechanism 32, an X-axis adjustment structure, and a Z-axis adjustment structure.

[0063] In some embodiments, the tube rack 119 includes a first guide rail 321 extending along the X-axis and a first sliding member 322 slidably assembled on the first guide rail 321, with the gas-liquid tube 332 located on the first sliding member 322; the tube rack 19 also includes a second guide rail 225 extending along the Z-axis and a second sliding member 226 slidably assembled on the second guide rail 225, with the first guide rail 221 fixed on the second sliding member 226; the tube rack 19 also includes a third guide rail 227 extending along the Y-axis and a third sliding member 228 slidably assembled on the third guide rail 227, with the second guide rail 225 fixed on the third sliding member 228.

[0064] The tube rack 19 includes a first guide rail 221 extending along the X-axis and a first sliding member 222 slidably assembled on the first guide rail 221, with the gas-liquid tube 232 located on the first sliding member 222.

[0065] In this embodiment, since the first guide rail 221 extends along the X-axis direction and the gas-liquid pipe 232 is disposed on the first sliding member 222, when the first sliding member 222 slides along the first guide rail 221, the gas-liquid pipe 232 can move along the X-axis direction, thereby realizing the position adjustment of the gas-liquid pipe 232 in the X-axis direction.

[0066] It should be noted that the first sliding member 222 has two notches 28, and there are two gas-liquid pipes 232, one of which is a gas-liquid inlet pipe and the other is a gas-liquid outlet pipe. The gas-liquid inlet pipe and the gas-liquid outlet pipe are respectively engaged within the two notches 28. Furthermore, the gas-liquid inlet pipe and the gas-liquid outlet pipe are required to be as vertical as possible within the two notches 28, which facilitates the alignment and assembly of the gas-liquid pipe 232 with the main body 233. After the gas-liquid inlet pipe and the gas-liquid outlet pipe are aligned and assembled with the main body 233 of the heat exchanger 23, the airtightness of the heat exchanger can be tested by allowing air to enter through the gas-liquid inlet pipe and exit through the gas-liquid outlet pipe. Simultaneously, refrigerant can also be injected into the heat exchanger through the gas-liquid inlet pipe.

[0067] The first guide rail 231 has a plurality of first slots 24, and each first slot 24 is distributed sequentially at intervals along the extension direction of the first guide rail 221. The first sliding member 222 has a first mounting hole, and a first elastic member 223 and a first locking member 224 connected to the free end of the first elastic member 223 are installed in the first mounting hole. The first locking member 224 can engage with any of the first slots 34.

[0068] In this technical solution, since the first locking member 224 can engage with any of the first slots 24, after the first sliding member 222 slides into place along the first guide rail 221, the first locking member 224 engages with the first slot 24, thereby positioning the first sliding member 222 on the first guide rail 221, and thus positioning the gas-liquid pipe 232 after its position is adjusted along the X-axis.

[0069] The first card 224 is a spherical body, and the volume of the first card 224 in any first card slot 24 is less than or equal to half the volume of the first card 224.

[0070] In this embodiment, when the volume of the spherical first locking member 224 within any first locking slot 24 is less than or equal to half of its own volume, it can not only achieve the engagement of the first locking member 224 with any first locking slot 24, but also, when adjusting the position of the first sliding member 222, simply moving the first sliding member 222 along the first guide rail 221 will automatically move the first locking member 224 out of the first locking slot 24, thus making the position adjustment of the first sliding member 22 on the first guide rail 221 more convenient. This is mainly because when no more than half of the volume of the sphere is within the first locking slot 24, if the sphere is subjected to an external force along the X-axis, it will easily and automatically disengage from the first locking slot 24; while when the first sliding member 222 is not subjected to an external force, the elastic force applied by the first elastic member 223 to the sphere will cause the sphere to engage within the first locking slot 24, thereby achieving the positioning of the first sliding member 222 on the first guide rail 221.

[0071] The steel frame 119 also includes a second guide rail 225 extending along the Z-axis and a second sliding member 226 slidably assembled on the second guide rail 225, with the first guide rail 221 fixed on the second sliding member 226.

[0072] In this technical solution, since the second guide rail 225 extends along the Z-axis direction, and the first guide rail 221 is fixed on the second sliding member 226, when the second sliding member 226 slides along the second guide rail 225, the gas-liquid pipe 232 can move along the Z-axis direction, thereby achieving position adjustment of the gas-liquid pipe 232 in the Z-axis direction. Preferably, there are two second guide rails 225, and the second sliding member 226 is simultaneously slidably disposed on both second guide rails 225, which makes the movement of the first guide rail 221 by the second sliding member 226 more stable.

[0073] In one specific implementation, a plurality of second slots 25 are constructed on the second guide rail 225, and each second slot 25 is distributed sequentially at intervals along the extension direction of the second guide rail 225. A second mounting hole is constructed on the second sliding member 226, and a second elastic member and a second locking member connected to the free end of the second elastic member are installed in the second mounting hole. The second locking member can engage with any of the second slots 25.

[0074] In this embodiment, since the second locking member can engage with any of the second slots 25, after the second sliding member 226 slides into place along the second guide rail 225, the second locking member engages with the second slot 225 to position the second sliding member 226 on the second guide rail 225, thereby achieving the positioning of the gas-liquid pipe 232 after its position is adjusted along the Z-axis.

[0075] More specifically, the second card is a spherical body, and the volume of the second card in any second card slot 5 is less than or equal to half the volume of the second card.

[0076] In this technical solution, when the volume of the spherical second locking member within any second slot 25 is less than or equal to half of its own volume, it can both engage with any second slot 25 and, when adjusting the position of the second sliding member 226, simply moving the second sliding member 226 along the second guide rail 225 will automatically remove the second locking member from the second slot 25, making position adjustment of the second sliding member 226 on the second guide rail 225 more convenient. This is mainly because when no more than half of the spherical body's volume is within the second slot 25, it will easily and automatically disengage from the second slot 25 if subjected to an external force along the Z-axis; while when the second sliding member 226 is not subjected to external force, the elastic force applied by the second elastic member to the spherical body will cause the spherical body to engage within the second slot 25, thereby achieving positioning of the second sliding member 226 on the second guide rail 225. It should be noted that the combination of the second elastic member and the second locking member can be a combination of the first elastic member 223 and the first locking member 224.

[0077] The tube rack 119 also includes a third guide rail 227 extending along the Y-axis and a third sliding member 228 slidably assembled on the third guide rail 227, with the second guide rail 225 fixed on the third sliding member 228.

[0078] In this technical solution, since the third guide rail 227 extends along the Y-axis direction and the second guide rail 225 is fixed on the third sliding member 228, when the third sliding member 228 slides along the third guide rail 227, the gas-liquid pipe 232 can move along the Y-axis direction, thereby realizing the position adjustment of the gas-liquid pipe 232 in the Y-axis direction.

[0079] In one specific implementation, the third guide rail 227 is provided with a plurality of third slots 26, and each third slot 26 is distributed sequentially at intervals along the extension direction of the third guide rail 227. The third sliding member 228 is provided with a third mounting hole, and a third elastic member and a third locking member connected to the free end of the third elastic member are installed in the third mounting hole. The third locking member can engage with any of the third slots 26.

[0080] In this embodiment, since the third locking member can engage with any of the third slots 26, after the third sliding member 228 slides into place along the third guide rail 227, the third locking member engages with the third slot 26 to position the third sliding member 228 on the third guide rail 227, thereby achieving the positioning of the gas-liquid pipe 232 after its position is adjusted along the Y-axis.

[0081] More specifically, the third card is a spherical body, and the volume of the third card in any third card slot 26 is less than or equal to half the volume of the third card.

[0082] In this technical solution, when the volume of the spherical third locking member within any third locking slot 26 is less than or equal to half of its own volume, it can not only achieve engagement between the third locking member and any third locking slot 26, but also, when adjusting the position of the third sliding member 228, simply moving the third sliding member 228 along the third guide rail 227 will automatically remove the third locking member from the third locking slot 26, making the position adjustment of the third sliding member 28 on the third guide rail 227 more convenient. This is mainly because when no more than half of the spherical body's volume is within the third locking slot 26, if the spherical body is subjected to an external force along the Y-axis, it will easily and automatically detach from the third locking slot 226; while when the third sliding member 228 is not subjected to an external force, the elastic force applied by the third elastic member to the spherical body will cause the spherical body to engage within the third locking slot 26, thereby achieving the positioning of the third sliding member 228 on the third guide rail 227. It should be noted that the combination of the third elastic member and the third locking member can be a combination of the first elastic member 223 and the first locking member 224.

[0083] In some embodiments, a sixth driving member 114 is provided on the first mounting bracket, and a Y-axis tube frame adjustment plate 16 is provided on the output end of the sixth driving member 114. The sixth driving member 114 can drive the Y-axis tube frame adjustment plate 16 to adjust its position in the Y-axis direction so that the Y-axis tube frame adjustment plate 16 pushes the third sliding member 228 to move.

[0084] The third mounting bracket is provided with a base 115, and the base 115 is provided with a third guide rail extending along the Z-axis direction. The base 115 is provided with a third driving member 17, and the third guide rail is provided with a Z-axis tube frame adjustment plate 113. The output end of the third driving member 17 is connected to the Z-axis tube frame adjustment plate 113. The third driving member 17 can drive the Z-axis tube frame adjustment plate 113 to adjust its position along the third guide rail in the Z-axis direction, so that the Z-axis tube frame adjustment plate 113 pushes the second sliding member 226 to adjust its position along the second guide rail in the Z-axis direction.

[0085] The Y-axis tube rack adjusting plate 16 and the third sliding member 228 are arranged opposite each other. When the tube rack 119 needs to be adjusted in the Y-axis direction, the sixth driving member 114 can drive the Y-axis tube rack adjusting plate 16 to move toward the third sliding member 228, so that the third sliding member 228 drives the tube rack 119 to move along the Y-axis direction on the third guide rail 227. Furthermore, a locking hole can be provided on the third sliding member 228 and a locking member can be provided on the Y-axis tube rack adjusting plate 16. When the heat exchanger needs to be positioned, the Y-axis tube rack adjusting plate 16 can be connected to the third sliding member 228 through the locking member and the locking hole, so as to realize the real-time adjustment of the tube rack 119 in the Y-axis direction. When not working, the Y-axis tube rack adjusting plate 16 and the third sliding member 228 can be separated, and the first mounting bracket, the second mounting bracket and the third mounting bracket can be placed separately for easy storage of the first mounting bracket, the second mounting bracket and the third mounting bracket.

[0086] The Z-axis tube frame adjustment plate 113 is arranged opposite to the second sliding member 226. When the tube frame 119 needs to be adjusted in the Z-axis direction, the third driving member 17 can drive the Z-axis tube frame adjustment plate 113 to move toward the second sliding member 226, so that the second sliding member 226 drives the tube frame 119 to move along the Z-axis direction on the second guide rail. Furthermore, when there are two second guide rails 225, the Z-axis tube frame adjustment plate 113 can extend between the two second guide rails, located above or below the movable member, so that the movable member can move in the Z-axis direction.

[0087] In some embodiments, the third mounting bracket is provided with a base 115, the base 115 is provided with a fourth guide rail extending along the X-axis direction, the fourth guide rail is provided with an X-axis tube frame adjustment plate 114, and the fourth guide rail is provided with a fourth driving member 118. The output end of the fourth driving member 118 is connected to the X-axis tube frame adjustment plate 114, and the fourth driving member 118 can drive the X-axis tube frame adjustment plate 114 to adjust its position along the fourth guide rail in the X-axis direction, so that the X-axis tube frame adjustment plate 114 pushes the first sliding member 322 to adjust its position along the first guide rail in the X-axis direction.

[0088] The X-axis tube support adjusting plate 14 is arranged opposite to the first sliding member 322. When the tube support 119 needs to be adjusted in the X-axis direction, the fourth driving member 18 can drive the X-axis tube support adjusting plate 14 to move toward the first sliding member 322 on the fourth guide rail. This causes the first sliding member 322 to move the tube support 119 along the X-axis direction on the first guide rail. Further, firstly, the base moves along the Y-axis direction, making the X-axis tube support adjusting plate 14 opposite to the first sliding member 322. Then, the fourth driving member 18 can drive the X-axis tube support adjusting plate 14 to move along the X-axis direction on the fourth guide rail. The X-axis tube support adjusting plate 14 pushes the first sliding member 322 to move along the X-axis direction on the first guide rail, thereby adjusting the position of the tube support 119 in the X-axis direction. When the first sliding member 322 has two notches, the X-axis tube support adjusting plate 14 can extend into either notch, pushing the first sliding member 322 to move along the X-axis direction on the first guide rail through the notch, thereby adjusting the position of the tube support 119 in the X-axis direction.

[0089] In one specific embodiment, the positioning mechanism includes a fixed plate 124, a first side plate 121, and a second side plate 123 assembled on one side of the first side plate 121. An angle is formed between the first side plate 121 and the second side plate 123. The main body fits against the first side plate 121 and the second side plate 123. The first side plate 121 and the second side plate 123 are disposed on the fixed plate 124. The first side plate 121 is fixedly connected to the fixed plate 124. A limiting member 122 is provided on the second side plate 123. The limiting member 122 can be engaged with the fixed plate 124. The position of the second side plate 123 relative to the first side plate 121 is adjustable.

[0090] In this technical solution, the positioning mechanism further includes a first positioning component and a second positioning component, and the main body is clamped between the first positioning component and the second positioning component.

[0091] The first positioning component includes a fixing plate 124, a first side plate 121, and a second side plate 123 assembled on one side of the first side plate 121. An angle is formed between the first side plate 121 and the second side plate 123. The main body fits the first side plate 121 and the second side plate 123. The first side plate 121 and the second side plate 123 are disposed on the fixing plate 124. The first side plate 121 is fixedly connected to the fixing plate 124. A limiting member 122 is provided on the second side plate 23. The limiting member 122 can be engaged with the fixing plate 124. The position of the second side plate 123 relative to the first side plate 121 is adjustable.

[0092] When the first part of the main body is clamped between the first side plate 121 and the second positioning assembly, and the second part of the main body is in contact with the second side plate 123, it indicates that the first positioning assembly can not only position flat-plate heat exchangers, but also two-section or more-section heat exchangers, thus broadening the applicability of the positioning device. For example, it can be applied to the condenser of the outdoor unit, and also to the evaporator of the indoor unit. It should be noted that the second positioning assembly 212 includes a connecting rod structure 2121 and a pressure plate 2122 fixed on the connecting rod structure 2121. A rubber pad is provided on the pressure plate 2122. The cylinder drives the connecting rod structure 2121 to move, thereby clamping the first part 2311 between the pressure plate 2122 and the first side plate. The rubber pad has a buffering effect, which can prevent the fins on the first part 2311 from falling over due to clamping. The connecting rod structure 2121 is designed with a limit mechanism to prevent the connecting rod structure 2121 from jamming. Furthermore, the design height of the second side plate is approximately one-third of the average height of the main body of all heat exchanger models. This allows a significant portion of the main body 31 of the heat exchanger to be exposed after it is positioned, making it easier for the robotic arm to grip and assemble the heat exchanger.

[0093] The first side plate 121 and the second side plate 123 are mounted on the fixed plate 124, and the first side plate 121 is fixedly connected to the fixed plate 124. A gap exists between the second side plate 123 and the fixed plate 124, and the position of the second side plate 123 relative to the first side plate 121 is adjustable. This allows the included angle between the second side plate 123 and the first side plate 121 to be adjusted, making the positioning mechanism applicable to various types of heat exchangers. More specifically, the second side plate 123 has three adjustment positions. When the second side plate 123 is in these three adjustment positions, the included angle between the second side plate 123 and the first side plate 121 is 70°, 75°, and 80°, respectively. Furthermore, the tube rack 119 can adjust the position of the gas-liquid pipe in the X, Y, and Z axes. Statistically, the positioning device of this application can accurately position 4 different structures and 26 different specifications of heat exchangers. It should also be noted that a limiting member 122 is provided on the second side plate 123. The limiting member 122 is used to fix the second side plate 123 at different angles to the fixing plate 124 to meet the requirements of heat exchangers of different specifications.

[0094] In one specific implementation, the third mounting bracket is provided with a base 115, and a seventh guide rail is provided on the base 115. The seventh guide rail has an angle with the Y-axis. An angle adjustment plate 13 is provided on the seventh guide rail, and a second driving member 12 is provided on the seventh guide rail. The output end of the second driving member 12 is connected to the angle adjustment plate 13. The second driving member 12 is used to drive the angle adjustment plate 113 to move along the seventh guide rail, so that the angle adjustment plate 13 can push the second side plate 123 to rotate relative to the first side plate 121, thereby adjusting the angle between the first side plate 121 and the second side plate 123.

[0095] In this technical solution, a seventh guide rail is provided on the base 115, and the seventh guide rail has an angle with the Y-axis. An angle adjustment plate 13 is provided on the seventh guide rail. When it is necessary to adjust the angle between the second side plate 123 and the first side plate 121, the second driving member 12 is used to drive the angle adjustment plate 13 to move along the seventh guide rail, so that the angle adjustment plate 13 can push the second side plate 123 to rotate relative to the first side plate 121, thereby adjusting the angle between the first side plate 121 and the second side plate 123. It should be noted that adjusting the seventh guide rail... When adjusting the angle between the first side plate 121 and the second side plate 123, firstly, open the limiting member 122 so that the first side plate 121 and the second side plate 123 are at their maximum angle. Then, the angle adjusting plate 13 can push the second side plate 123 to rotate relative to the first side plate 121, that is, the angle between the first side plate 121 and the second side plate 123 gradually decreases until the requirements of the heat exchanger are met. At this time, the limiting member 122 is engaged with the fixing plate 124, thereby fixing the angle between the first side plate 121 and the second side plate 123.

[0096] In one specific implementation, the fixing plate 124 is provided with a plurality of grooves, and the plurality of grooves are arranged at intervals along the movement direction of the second side plate 123, and the limiting member 122 is engaged with the grooves.

[0097] In this technical solution, multiple grooves are provided on the fixed plate 124, and the multiple grooves are arranged at intervals along the movement direction of the second side plate 123. The angle between the first side plate 121 and the second side plate 123 is fixed by the limiting member 122 engaging with the grooves, thereby meeting the needs of heat exchangers of various specifications.

[0098] In one specific implementation, the angle adjustment plate 113 has a notch at one end away from the second driving member. The notch matches the limiting member 122. The angle adjustment plate 3 can push the limiting member 122 so that the second side plate 123 rotates relative to the first side plate 121.

[0099] In this technical solution, a notch is provided at the end of the angle adjustment plate 13 away from the second driving member, that is, a notch is provided at the end of the angle adjustment plate 13 facing the limiting member 122. The notch is adapted to the limiting member 122. The angle adjustment plate 113 cooperates with the limiting member 122 through the notch, thereby pushing the second side plate 123 to move, so as to adjust the angle between the first side plate 121 and the second side plate 123.

[0100] In one specific embodiment, the limiting member 122 includes a housing 125 and a positioning pin 126. The positioning pin 126 passes through the housing 125 and is movable along the Y-axis on the housing 125. A baffle is provided on the positioning pin 126 and is located inside the housing 125. The baffle divides the space inside the housing 125 into a first cavity and a second cavity. An inlet 128 is provided on the housing 25 and communicates with the second cavity. An elastic member 127 is provided in the first cavity and is capable of driving the baffle to move within the housing 25.

[0101] In this technical solution, the limiting component 122 adopts a pneumatic pin. Specifically, the positioning pin 126 penetrates the housing 125 and can move along the Y-axis on the housing 125. A baffle is provided on the positioning pin 126, which is located inside the housing 125. The baffle divides the space inside the housing 125 into a first cavity and a second cavity. An inlet 128 is provided on the housing 125, which communicates with the second cavity. An elastic element 127 is provided in the first cavity, which can drive the baffle to move within the housing 125. When air pressure is applied to the inlet 128 from the outside, the air pressure in the second cavity increases, causing the baffle to move upward, which in turn drives the positioning pin 126 to move upward, that is, the positioning pin 126 separates from the fixed plate 124. One side of the second side plate 123 is provided with... A connecting rod is used, and the second side plate 123 and the first side plate 121 are all sleeved on the connecting rod. Grooves can be provided on the sides of the second side plate 123 and the first side plate 121 facing each other, so that the second side plate 123 and the first side plate 121 face each other in an interlaced structure. The connecting rod passes through the second side plate 123 and the first side plate 121 in sequence, allowing the second side plate 123 and the first side plate 121 to rotate. Furthermore, a spring can be provided on the connecting rod. When the positioning pin 126 is separated from the fixed plate 24, the second side plate 123 moves to the maximum angle with the first side plate 121 under the action of the spring. Then, the angle adjusting plate 13 adjusts the loosened second side plate 123 to the corresponding angle position. The pressure in the second cavity is released through the inlet 128, and the positioning pin 126 is engaged with the fixed plate 124 under the action of the elastic element, realizing the limiting of the second side plate 123. This achieves the effect of universal bending angle positioning of the heat exchanger. In this application, the elastic element can be a spring.

[0102] Finally, it should be noted that the entire operation process is as follows: Adjust the angle of the second side plate 123, place the main body between the first positioning component and the second positioning component, the cylinder drives the second positioning component to clamp the first part of the main body, the second part of the main body is close to the second side plate 123, the pipe rack 119 adjusts the position of the gas-liquid pipe in the three directions of X-axis, Y-axis and Z-axis to make the gas-liquid pipe and the main body accurately aligned, and finally assemble the gas-liquid pipe and the main body.

[0103] In one specific implementation, the first mounting bracket is provided with a support 111, the second mounting bracket is provided with a male connector 116, the support 111 is provided with a female connector 110, the air outlet of the male connector 116 is connected to the inlet 128, and the female connector 110 is connected to the air inlet of the male connector 116.

[0104] In this technical solution, a bracket 111 is provided on the first mounting frame, a male connector 116 is provided on the second mounting frame, and a female connector 110 is provided on the bracket 111. The air outlet of the male connector 116 is connected to the inlet 128 through a hose. The limiting member 122 is inflated and deflated by the female connector 110 and the male connector 116 to adjust the position of the second side plate 23.

[0105] In one specific implementation, the first mounting bracket is provided with an eighth track, the bracket 11 is disposed on the eighth track, the eighth track is provided with a fifth driving member 12, the output end of the fifth driving member 112 is connected to the bracket 111, the fifth driving member 112 is used to drive the bracket 111 to adjust its position along the eighth track in the Y-axis direction, the bracket 111 is provided with a seventh driving member 19, the output end of the seventh driving member 19 is connected to the docking female head 110, the seventh driving member 19 is used to drive the docking female head 110 to adjust its position in the Z-axis direction.

[0106] In this technical solution, the fifth driving component 112 is used to drive the bracket 11 to adjust its position along the eighth track in the Y-axis direction, and the seventh driving component 19 is used to drive the docking female head 110 to adjust its position in the Z-axis direction, so that the docking female head 110 can be adjusted in the Y-axis and Z-axis directions, so that the docking female head 110 can be docked with the docking male head 116.

[0107] In one specific implementation, the third mounting bracket is provided with a sixth guide rail and a first driving member 11. The base 115 is disposed on the sixth guide rail, which extends along the Y-axis direction. The output end of the first driving member 11 is connected to the base 115. The first driving member 11 is used to drive the base 115 to move along the sixth guide rail in the Y-axis direction.

[0108] In this technical solution, a sixth guide rail and a first driving component 11 are provided on the third mounting bracket to adjust the position of the base 115. When adjustment begins, since the tube frame 119 is located on the second mounting bracket, and the X-axis, Z-axis, and angle adjustment mechanism are all located on the third mounting bracket, if the distance between them is too great, effective adjustment of the tube frame 119 and the second side plate 123 is impossible. At this time, the first driving component 11 drives the base 115 to move along the sixth guide rail in the Y-axis direction, that is, the base 115 moves closer to the second mounting bracket, causing the X-axis, Z-axis, and angle adjustment mechanism to move closer to the tube frame 119 and the second side plate 123, ensuring normal adjustment of the tube frame 119 and the second side plate 123. All driving components in this application are pneumatic cylinders or electric cylinders.

[0109] It should be noted that a positioning device is also present on the entire production line. The main body 33 of the heat exchanger is fixed on the positioning mechanism 21 of the positioning device, and the gas-liquid pipe 331 of the heat exchanger is fixed on the adjustment mechanism 119 of the positioning device. The position of the gas-liquid pipe 331 in the X-axis, Y-axis, and Z-axis directions is adjusted by the adjustment mechanism 119 to ensure accurate alignment between the gas-liquid pipe 331 and the main body 33. Then, the gas-liquid pipe 331 and the main body 33 are assembled to form the heat exchanger. Next, the positioning device carries the heat exchanger from the production line to the docking device for the docking process. On the production line, both the positioning device and the docking device are located on the frame.

[0110] The female head drive component 314 has a first telescopic part and a second telescopic part. The docking female head 313 is assembled on the first telescopic part, and the gripper drive component 312 is assembled on the second telescopic part. The gripper drive component 312 is drivenly connected to the docking gripper 311. The docking gripper 311 and the docking female head 313 are distributed at intervals along the Z-axis direction, and the docking female head 313 is located below the docking gripper 311.

[0111] In this embodiment, after the gripper drive component 312 drives the docking gripper 311 to clamp the gas-liquid pipe 331, the first and second telescopic portions of the female head drive component 314 simultaneously extend and retract. The first telescopic portion drives the docking female head 313 to move upward, and the second telescopic portion drives the docking gripper 311 to move downward along the gas-liquid pipe 331. After both the first and second telescopic portions have extended and retracted to their positions, the docking female head 313 and the connector 332 are docked and locked together. It should be noted that the process of the second telescopic portion driving the docking gripper 311 to move downward along the gas-liquid pipe 331 helps to straighten the gas-liquid pipe 331, facilitating the accurate docking of the subsequent docking female head 313 and the connector 332. The female head drive component 314 can be a cylinder, an electric cylinder, a hydraulic cylinder, etc. Preferably, the female head drive component 314 is a cylinder, and both ends of the cylinder can extend and retract. Preferably, the gripper drive component 312 is a cylinder.

[0112] A docking groove 34 is formed on the docking head 313 facing the docking jaws 311. The docking groove 34 gradually expands in the direction from the docking head 313 to the docking jaws 311.

[0113] In this technical solution, the mating groove 34 gradually expands from the mating female head 313 to the mating jaws 311. This creates a guiding oblique arc surface on the groove wall of the mating groove 34, which guides the connection of the connector 332, improving mating accuracy and reducing the probability of hard contact during the mating process. The connector 332 has a push pin; after the mating female head 313 and connector 332 are mated and secured, the push pin on the connector 332 is lifted, thus opening the gas-liquid pipe 331. The mating female head 313 also has a channel communicating with the mating groove 34. After the mating female head 313 and connector 332 are mated and secured, air and helium can be injected into the heat exchanger through the mating female head 313 for air leak detection and helium leak detection. After the heat exchanger's sealing is confirmed to be satisfactory, refrigerant is injected for refrigerant filling. Furthermore, the connector 332 has a groove, and the mating head 313 has a ball. After the connector 332 is inserted into the mating head 313, the ball is engaged in the groove to lock the connector 332 and the mating head 313 together.

[0114] It should be noted that the docking female head 313 is assembled on the first telescopic part via a bracket, on which a dust cover 37 and a dustproof cylinder 38 are also assembled. When the docking device is idle, the dustproof cylinder 38 drives the dust cover 37 to cover the docking groove 34 to prevent dust from falling into the docking groove 34; when the docking device is working, the dustproof cylinder 38 drives the dust cover 37 to move away, exposing the docking groove 34 for subsequent docking operations.

[0115] The docking jaw 311 has a guide area 35 and a clamping area 36. The clamping area 36 is connected to the guide area 35 and is located at the tail of the guide area 35. The guide area 35 gradually expands in the direction from the tail of the guide area 35 to the front of the guide area 35.

[0116] In this embodiment, the guide area 35 gradually expands from its tail to its front, creating a flared structure. This provides better guidance, allowing the docking jaws 311 to adapt to gas-liquid pipes 331 of different diameters, expanding the clamping range, improving docking tolerance, and making it suitable for different types of heat exchangers 3. It should be noted that after the gas-liquid pipe is guided by the guide area 35, it is ultimately clamped by the clamping area 36, ​​which is a circular groove. During docking, the docking jaws 311 are adjusted to reach 50mm above the joint 332, and then the gas-liquid pipe is accommodated in the circular groove of the docking jaws 311.

[0117] The position adjustment mechanism 32 includes a first telescopic component 321, which is configured to extend and retract along the Z-axis direction, and a docking mechanism 31 is assembled on the telescopic portion of the first telescopic component 321.

[0118] In this technical solution, the docking mechanism 31 is positioned in the Z-axis direction by extending and retracting the first telescopic component 321 along the Z-axis, thereby adjusting the positions of the docking jaws 311 and the docking head 313 in the Z-axis direction. The first telescopic component 321 can be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc., and preferably, it is an electric cylinder.

[0119] In one specific implementation, there are two gas-liquid pipes, and each of the free ends of the two gas-liquid pipes is provided with a connector 332. There are two first telescopic components 321 and two docking mechanisms 31. The two docking mechanisms 1 are respectively assembled on the telescopic parts of the two first telescopic components 321.

[0120] In this embodiment, the two gas-liquid pipes are a gas-liquid inlet pipe and a gas-liquid outlet pipe, respectively. During air leak detection and helium leak detection, air and helium enter through the gas-liquid inlet pipe and exit through the gas-liquid outlet pipe. During refrigerant charging, refrigerant is charged into the heat exchanger through the gas-liquid inlet pipe. Each docking mechanism includes a docking jaw 311, a jaw driving component 312, a docking female head 313, and a female head driving component 314. The two docking mechanisms 31 are respectively assembled on the telescopic parts of the two first telescopic components 321, which can realize that the two first telescopic components 321 can adjust the position of the two docking mechanisms 31 in the Z-axis direction. The position adjustment of the two docking mechanisms 31 is independent of each other and does not interfere with each other, ultimately realizing that the two docking mechanisms 1 can clamp and dock the two gas-liquid pipes 331 respectively.

[0121] The position adjustment mechanism 2 also includes a support frame 322 and a second telescopic component 323. The first telescopic component 321 is assembled on the support frame 322, and the second telescopic component 323 is configured to telescopically extend and retract along the Y-axis direction. The support frame 322 is assembled on the telescopic portion of the second telescopic component 323.

[0122] In this technical solution, since the support frame 322 is assembled on the telescopic part of the second telescopic component 323, when the second telescopic component 323 extends or retracts along the Y-axis, it can drive the support frame 322 to adjust its position along the Y-axis. Furthermore, since the docking mechanism 31 is assembled on the telescopic part of the first telescopic component 321, and the first telescopic component 321 is assembled on the support frame 322, when the second telescopic component 323 drives the support frame 322 to adjust its position along the Y-axis, the docking mechanism 31 can also adjust its position along the Y-axis. The second telescopic component 323 can be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc., preferably an electric cylinder.

[0123] The position adjustment mechanism 32 also includes a tenth guide rail 324, which extends along the Y-axis, and the support frame 322 can be slidably assembled on the tenth guide rail 324.

[0124] In this embodiment, the tenth guide rail 324 can provide support and guidance for the support frame 322, so that when the second telescopic component 323 adjusts the position of the support frame 322 along the Y-axis, it ensures the stability and directional accuracy of the support frame 322 when it moves along the Y-axis, thereby ensuring the stability and accuracy of the position adjustment of the docking mechanism 31 in the Y-axis direction.
