Description

[0002] Currently, in the air conditioning manufacturing industry, the production of evaporators for indoor air conditioning units involves a process of separately positioning the evaporator body and the gas-liquid pipes before assembling them. The positioning of both the evaporator body and the gas-liquid pipes is done manually, which is not only labor-intensive but also inefficient. After the gas-liquid pipes and body are assembled, operations such as air leak detection, helium leak detection, and refrigerant charging can be performed on the evaporator through the gas-liquid pipes.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Referring to Figures 1 to 9, according to an embodiment of the present invention, an adjustment device is provided, including a positioning mechanism and a tube support 19. The positioning mechanism is used to position the main body of the heat exchanger 5, and the tube support 19 is used to position the gas-liquid pipes of the heat exchanger 5.

[0038] The adjustment device further includes a first mounting frame, a second mounting frame, and a third mounting frame arranged sequentially. The positioning mechanism and the pipe rack 19 are mounted on the second mounting frame. The first mounting frame is provided with a Y-axis adjustment structure, which is used to adjust the position of the pipe rack 19 in the Y-axis direction. The third mounting frame is provided with an X-axis adjustment structure and a Z-axis adjustment structure, which are used to adjust the position of the pipe rack 19 in both the X-axis and Z-axis directions so that the gas-liquid pipe is aligned with the main body.

[0039] In this technical solution, the main body of the heat exchanger 5 is first positioned using a positioning mechanism. Then, the position of the gas-liquid pipes is adjusted using the tube rack 19 to ensure accurate alignment between the gas-liquid pipes and the main body. Next, the tube rack 19 is used to position the adjusted gas-liquid pipes. Finally, the main body and gas-liquid pipes are assembled to form the heat exchanger 5. After the main body and gas-liquid pipes are initially positioned and aligned using the positioning mechanism and tube rack 19, 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 prone 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.

[0040] In one specific embodiment, the pipe rack 19 includes a first guide rail extending along the X-axis and a fixing member 20 slidably assembled on the first guide rail, with the gas-liquid pipe located on the fixing member 20; the pipe rack 19 also includes a second guide rail extending along the Z-axis and a movable member slidably assembled on the second guide rail, with the first guide rail fixed on the movable member; the pipe rack 19 also includes a fifth guide rail 17 extending along the Y-axis and a first sliding member 18 slidably assembled on the fifth guide rail 17, with the second guide rail fixed on the first sliding member 18.

[0041] In this technical solution, the gas-liquid pipe is fixed by the fixing member 20, and then the fixing member 20 can be moved in the X-axis direction by the first guide rail, the fixing member 20 can be moved in the Z-axis direction by the second guide rail and the movable member, and the fixing member 20 can be moved in the Y-axis direction by the first sliding member 18 and the fifth guide rail 17, thereby meeting the size requirements of heat exchangers 5 of different specifications.

[0042] Furthermore, the first guide rail extends along the X-axis direction, and the gas-liquid pipe is mounted on the fixing member 20. Therefore, when the fixing member 20 slides along the first guide rail, the gas-liquid pipe can move along the X-axis direction, thereby realizing the position adjustment of the gas-liquid pipe in the X-axis direction.

[0043] Two notches are formed on the fastener 20, and there are two gas-liquid pipes, one for gas-liquid inlet and the other for gas-liquid outlet. The gas-liquid inlet and outlet pipes are respectively engaged within the two notches. It is required that the gas-liquid inlet and outlet pipes be as vertical as possible within the two notches, which facilitates the alignment and assembly of the gas-liquid pipes with the main body. After the gas-liquid inlet and outlet pipes are aligned and assembled with the main body of the heat exchanger 5, 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.

[0044] Furthermore, the first guide rail is provided with a plurality of first slots, which are distributed sequentially at intervals along the extension direction of the first guide rail. The fixing member 20 is provided with a first mounting hole, in which a first elastic member and a first locking member connected to the free end of the first elastic member are installed. The first locking member can engage with any of the first slots.

[0045] Since the first locking member can engage with any of the first slots, after the fixing member 20 slides into place along the first guide rail, the fixing member 20 is positioned on the first guide rail by engaging with the first slot, thereby achieving the positioning of the gas-liquid pipe after the position is adjusted along the X-axis.

[0046] The first card is a spherical object, and the volume of the first card in any first card slot is less than or equal to half the volume of the first card.

[0047] When the volume of the spherical first locking member within any first locking slot is less than or equal to half of its own volume, it can engage with any first locking member. Furthermore, when adjusting the position of the fixing member 20, simply moving the fixing member along the first guide rail automatically moves the first locking member out of the first locking slot, making position adjustment of the fixing member 20 on the first guide rail more convenient. This is mainly because when no more than half of the spherical body's volume is within the first locking slot, it will easily and automatically disengage from the first locking slot if subjected to an external force along the X-axis. Conversely, when the fixing member 20 is not subjected to external force, the elastic force applied by the first elastic member to the spherical body will cause the spherical body to engage within the first locking slot, thus positioning the first sliding member on the first guide rail.

[0048] The second guide rail extends along the Z-axis, while the first guide rail is fixed to the movable component. Therefore, when the movable component slides along the second guide rail, the gas-liquid pipe can move along the Z-axis, thereby adjusting the position of the gas-liquid pipe in the Z-axis direction. Preferably, there are two second guide rails, and the movable component slides on both second guide rails simultaneously, which makes the movement of the first guide rail by the movable component more stable.

[0049] In one specific implementation, a plurality of second slots are constructed on the second guide rail, and the second slots are distributed sequentially at intervals along the extension direction of the second guide rail. A second mounting hole is constructed on the second sliding member, 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.

[0050] The second locking component can engage with any of the second slots. Therefore, after the movable component slides into place along the second guide rail, the second locking component engages with the second slot to position the second sliding component on the second guide rail, thereby achieving the positioning of the gas-liquid pipe after its position is adjusted along the Z-axis.

[0051] The second card is a spherical object, 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.

[0052] When the volume of the spherical second locking member within any second locking slot is less than or equal to half of its own volume, it can engage with either second locking slot. Furthermore, when adjusting the position of the movable part, simply moving the movable part along the second guide rail will automatically remove the second locking member from the second locking slot, making position adjustment on the second guide rail more convenient. This is mainly because when no more than half of the spherical body's volume is within the second locking slot, it will easily and automatically disengage from the slot if subjected to an external force along the Z-axis. Conversely, when the movable part 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 locking slot, thus achieving positioning of the movable part on the second guide rail.

[0053] The fifth guide rail 17 extends along the Y-axis, while the second guide rail is fixed on the first sliding member 18. Therefore, when the first sliding member 18 slides along the fifth guide rail 17, the gas-liquid pipe can move along the Y-axis, thereby realizing the position adjustment of the gas-liquid pipe in the Y-axis direction.

[0054] The fifth guide rail 17 has multiple third slots, which are distributed sequentially at intervals along the extension direction of the fifth guide rail 17. The first sliding member 18 has a third mounting hole, in which a third elastic member and a third locking member connected to the free end of the third elastic member are installed. The third locking member can engage with any of the third slots.

[0055] The third locking component can engage with any third slot. Therefore, after the first sliding member 18 slides into place along the fifth guide rail 17, the third locking component engages with the third slot to position the first sliding member 18 on the fifth guide rail 17, thereby achieving the positioning of the gas-liquid pipe 32 after its position is adjusted along the Y-axis.

[0056] Specifically, the first mounting bracket, the positioning mechanism, the pipe rack 19, and the third mounting bracket are arranged in sequence. That is, the positioning mechanism is located between the first mounting bracket and the pipe rack 19, the pipe rack 19 is located between the positioning mechanism and the third mounting bracket, and the positioning mechanism and the pipe rack 19 are arranged at intervals.

[0057] In one specific implementation, a sixth driving member 14 is provided on the first mounting bracket, and a Y-axis tube frame adjustment plate 6 is provided on the output end of the sixth driving member 14. The sixth driving member 14 can drive the Y-axis tube frame adjustment plate 6 to adjust its position in the Y-axis direction, so that the Y-axis tube frame adjustment plate 6 pushes the first sliding member 18 to move.

[0058] In this technical solution, the Y-axis tube rack adjusting plate 6 is arranged opposite to the first sliding member 18. When the tube rack 19 needs to be adjusted in the Y-axis direction, the sixth driving member 14 can drive the Y-axis tube rack adjusting plate 6 to move toward the first sliding member 18, so that the first sliding member 18 drives the tube rack 19 to move along the Y-axis direction on the fifth guide rail 17. Furthermore, a locking hole can be provided on the first sliding member 18 and a locking member can be provided on the Y-axis tube rack adjusting plate 6. When the heat exchanger 5 needs to be positioned, the Y-axis tube rack adjusting plate 6 can be connected to the first sliding member 18 through the locking member and the locking hole, thereby realizing the real-time adjustment of the tube rack 19 in the Y-axis direction. When not working, the Y-axis tube rack adjusting plate 6 and the first sliding member 18 can be separated, and the first mounting bracket, the second mounting bracket and the third mounting bracket can be placed separately, which is convenient for the storage of the first mounting bracket, the second mounting bracket and the third mounting bracket.

[0059] In one specific implementation, the third mounting bracket is provided with a base 15, the base 15 is provided with a third guide rail extending along the Z-axis direction, the base 15 is provided with a third driving member 7, and the third guide rail is provided with a Z-axis tube frame adjustment plate 13. The output end of the third driving member 7 is connected to the Z-axis tube frame adjustment plate 13. The third driving member 7 can drive the Z-axis tube frame adjustment plate 13 to adjust its position along the third guide rail in the Z-axis direction, so that the Z-axis tube frame adjustment plate 13 pushes the movable member to adjust its position along the second guide rail in the Z-axis direction.

[0060] In this technical solution, the Z-axis tube frame adjustment plate 13 is arranged opposite to the movable part. When the tube frame 19 needs to be adjusted in the Z-axis direction, the third driving part 7 can drive the Z-axis tube frame adjustment plate 13 to move toward the movable part, thereby causing the movable part to drive the tube frame 19 to move along the Z-axis direction on the second guide rail. Furthermore, when there are two second guide rails, the Z-axis tube frame adjustment plate 13 can extend between the two second guide rails, located above or below the movable part, thereby causing the movable part to move in the Z-axis direction.

[0061] In one specific implementation, the third mounting bracket is provided with a base 15, the base 15 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 4, and the fourth guide rail is provided with a fourth driving member 8. The output end of the fourth driving member 8 is connected to the X-axis tube frame adjustment plate 4, and the fourth driving member 8 can drive the X-axis tube frame adjustment plate 4 to adjust its position along the fourth guide rail in the X-axis direction, so that the X-axis tube frame adjustment plate 4 pushes the fixing member 20 to adjust its position along the first guide rail in the X-axis direction.

[0062] In this technical solution, the X-axis tube frame adjustment plate 4 is arranged opposite to the fixing member 20. When the tube frame 19 needs to be adjusted in the X-axis direction, the fourth driving member 8 can drive the X-axis tube frame adjustment plate 4 to move towards the fixing member 20 on the fourth guide rail, thereby causing the fixing member 20 to drive the tube frame 19 to move 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 frame adjustment plate 4 opposite to the fixing member 20. Then, the fourth driving member 8 can drive the X-axis tube frame adjustment plate 4 to move along the X-axis direction on the fourth guide rail. The X-axis tube frame adjustment plate 4 pushes the fixing member 20 to move along the X-axis direction on the first guide rail, thereby adjusting the position of the tube frame 19 in the X-axis. When the fixing member 20 has two notches, the X-axis tube frame adjustment plate 4 can extend into either notch, pushing the fixing member 20 to move along the X-axis direction on the first guide rail through the notch, thereby adjusting the position of the tube frame 19 in the X-axis.

[0063] In one specific embodiment, the positioning mechanism includes a fixed plate 24, a first side plate 21, and a second side plate 23 assembled on one side of the first side plate 21. The first side plate 21 and the second side plate 23 form an included angle. The main body fits the first side plate 21 and the second side plate 23. The first side plate 21 and the second side plate 23 are disposed on the fixed plate 24, and the first side plate 21 is fixedly connected to the fixed plate 24. The second side plate 23 is provided with a limiting member 22, which can be engaged with the fixed plate 24. The position of the second side plate 23 relative to the first side plate 21 is adjustable.

[0064] 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.

[0065] The first positioning component includes a fixing plate 24, a first side plate 21, and a second side plate 23 assembled on one side of the first side plate 21. The first side plate 21 and the second side plate 23 form an included angle. The main body fits the first side plate 21 and the second side plate 23. The first side plate 21 and the second side plate 23 are disposed on the fixing plate 24, and the first side plate 21 is fixedly connected to the fixing plate 24. The second side plate 23 is provided with a limiting member 22, which can be engaged with the fixing plate 24. The position of the second side plate 23 relative to the first side plate 21 is adjustable.

[0066] When the first part of the main body is clamped between the first side plate 21 and the second positioning component, and the second part of the main body is in contact with the second side plate 23, it indicates that the first positioning component 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 the evaporator of the indoor unit. It should be noted that the second positioning component includes a connecting rod structure and a pressure plate fixed on the connecting rod structure. A rubber pad is provided on the pressure plate. The cylinder drives the connecting rod structure to move, thereby clamping the first part between the pressure plate and the first side plate 21. The rubber pad has a cushioning effect, which can prevent the fins on the first part from falling over due to clamping. The connecting rod structure is designed with a limit mechanism to prevent the connecting rod structure from jamming. Furthermore, the design height of the second positioning plate is approximately 1 / 3 of the average height of the main body of all models of heat exchangers 5. This will allow a considerable portion of the main body of the heat exchanger 5 to be exposed after positioning, thus facilitating the robotic arm to grip and assemble the heat exchanger 5.

[0067] The first side plate 21 and the second side plate 23 are mounted on the fixed plate 24, and the first side plate 21 is fixedly connected to the fixed plate 24. There is a gap between the second side plate 23 and the fixed plate 24, and the position of the second side plate 23 relative to the first side plate 21 is adjustable. This allows the included angle between the second side plate 23 and the first side plate 21 to be adjusted, thus the positioning mechanism of this application can be applied to various types of heat exchangers. More specifically, the second side plate 23 has three adjustment positions. When the second side plate 23 is in these three adjustment positions, the included angle between the second side plate 23 and the first side plate 21 is 70°, 75°, and 80°, respectively. In addition, the tube rack 19 can adjust the position of the gas-liquid pipe in the X, Y, and Z axes. According to statistics, the positioning device of this application can be used for the precise positioning of 4 different structures and 26 different specifications of heat exchangers. It should also be noted that a limiting member 22 is provided on the second positioning plate 112. The limiting member 22 is used to fix the second side plate 23 at different angles to the fixing plate 24 to meet the requirements of heat exchangers 5 of different specifications.

[0068] In one specific implementation, the third mounting bracket is provided with a base 15, and a seventh guide rail is provided on the base 15. The seventh guide rail has an angle with the Y-axis. An angle adjustment plate 3 is provided on the seventh guide rail, and a second driving member 2 is provided on the seventh guide rail. The output end of the second driving member 2 is connected to the angle adjustment plate 3. The second driving member 2 is used to drive the angle adjustment plate 3 to move along the seventh guide rail, so that the angle adjustment plate 3 can push the second side plate 23 to rotate relative to the first side plate 21, thereby adjusting the angle between the first side plate 21 and the second side plate 23.

[0069] In this technical solution, a seventh guide rail is provided on the base 15, and the seventh guide rail has an angle with the Y-axis. An angle adjustment plate 3 is provided on the seventh guide rail. When it is necessary to adjust the angle between the second side plate 23 and the first side plate 21, the second driving member 2 is used to drive the angle adjustment plate 3 to move along the seventh guide rail, so that the angle adjustment plate 3 can push the second side plate 23 to rotate relative to the first side plate 21, thereby adjusting the angle between the first side plate 21 and the second side plate 23. It should be noted that when adjusting the angle between the first side plate 21 and the second side plate 23, the limiting member 22 is first opened so that the first side plate 21 and the second side plate 23 are at the maximum angle position. Then, the angle adjustment plate 3 can push the second side plate 23 to rotate relative to the first side plate 21, that is, the angle between the first side plate 21 and the second side plate 23 gradually decreases until the requirements of the heat exchanger 5 are met. At this time, the limiting member 22 is engaged with the fixing plate 24, thereby fixing the angle between the first side plate 21 and the second side plate 23.

[0070] In one specific implementation, the fixing plate 24 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 23, and the limiting member 22 is engaged with the grooves.

[0071] In this technical solution, multiple grooves are provided on the fixed plate 24, and the multiple grooves are arranged at intervals along the movement direction of the second side plate 23. The angle between the first side plate 21 and the second side plate 23 is fixed by the limiting member 22 engaging with the grooves, thereby meeting the requirements of heat exchangers 5 of various specifications.

[0072] In one specific implementation, the angle adjustment plate 3 has a notch at one end away from the second driving member. The notch matches the limiting member 22. The angle adjustment plate 3 can push the limiting member 22 so that the second side plate 23 rotates relative to the first side plate 21.

[0073] In this technical solution, a notch is provided at the end of the angle adjustment plate 3 away from the second driving member, that is, a notch is provided at the end of the angle adjustment plate 3 facing the limiting member 22. The notch is adapted to the limiting member 22. The angle adjustment plate 3 cooperates with the limiting member 22 through the notch, thereby pushing the second side plate 23 to move, so as to adjust the angle between the first side plate 21 and the second side plate 23.

[0074] In one specific embodiment, the limiting member 22 includes a housing 25 and a positioning pin 26. The positioning pin 26 passes through the housing 25 and is movable along the Y-axis on the housing 25. A baffle is provided on the positioning pin 26 and is located inside the housing 25. The baffle divides the space inside the housing 25 into a first cavity and a second cavity. An inlet 28 is provided on the housing 25 and communicates with the second cavity. An elastic member 27 is provided in the first cavity and is capable of driving the baffle to move within the housing 25.

[0075] In this technical solution, the limiting component 22 adopts a pneumatic pin. Specifically, the positioning pin 26 penetrates the housing 25 and can move along the Y-axis on the housing 25. A baffle is provided on the positioning pin 26, which is located inside the housing 25. The baffle divides the space inside the housing 25 into a first cavity and a second cavity. An inlet 28 is provided on the housing 25, which communicates with the second cavity. An elastic element 27 is provided in the first cavity, which can drive the baffle to move within the housing 25. When air pressure is applied to the inlet 28 from the outside, the air pressure in the second cavity increases, causing the baffle to move upward, which in turn drives the positioning pin 26 to move upward, that is, the positioning pin 26 separates from the fixed plate 24. One side of the second side plate 23 is provided with A connecting rod is provided, and both the second side plate 23 and the first side plate 21 are fitted onto the connecting rod. Grooves can be provided on the sides of the second side plate 23 and the first side plate 21 facing each other, so that the second side plate 23 and the first side plate 21 face each other in an interlaced structure. The connecting rod passes through the second side plate 23 and the first side plate 21 in sequence, allowing the second side plate 23 and the first side plate 21 to rotate. Furthermore, a spring can be provided on the connecting rod. When the positioning pin 26 separates from the fixed plate 24, the second side plate 23 moves to the maximum angle with the first side plate 21 under the action of the spring. Then, the angle adjusting plate 3 adjusts the loosened second side plate 23 to the corresponding angle position. The pressure in the second cavity is released through the inlet 28, and the positioning pin 26 engages with the fixed plate 24 under the action of the elastic element, thereby limiting the position of the second side plate 23. This achieves the effect of universal bending angle positioning for the heat exchanger. In this application, the elastic element can be a spring.

[0076] Finally, it should be noted that the entire operation process is as follows: Adjust the angle of the second side plate 23, 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 23, the pipe rack 19 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.

[0077] In one specific implementation, the first mounting bracket is provided with a support 11, the second mounting bracket is provided with a male connector 16, the support 11 is provided with a female connector 10, the air outlet of the male connector 16 is connected to the inlet 28, and the female connector 10 is connected to the air inlet of the male connector 16.

[0078] In this technical solution, a bracket 11 is provided on the first mounting frame, a male connector 16 is provided on the second mounting frame, and a female connector 10 is provided on the bracket 11. The air outlet of the male connector 16 is connected to the inlet 28 through a hose. The limiting member 22 is inflated and deflated by the female connector 10 and the male connector 16 to adjust the position of the second side plate 23.

[0079] 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 12 is connected to the bracket 11, the fifth driving member 12 is used to drive the bracket 11 to adjust its position along the eighth track in the Y-axis direction, the bracket 11 is provided with a seventh driving member 9, the output end of the seventh driving member 9 is connected to the docking female head 10, the seventh driving member 9 is used to drive the docking female head 10 to adjust its position in the Z-axis direction.

[0080] In this technical solution, the fifth driving component 12 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 9 is used to drive the docking female head 10 to adjust its position in the Z-axis direction, so that the docking female head 10 can be adjusted in the Y-axis and Z-axis directions, and the docking female head 10 can be docked with the docking male head 16.

[0081] In one specific implementation, the third mounting bracket is provided with a sixth guide rail and a first driving member 1. The base 15 is disposed on the sixth guide rail, which extends along the Y-axis. The output end of the first driving member 1 is connected to the base 15. The first driving member 1 is used to drive the base 15 to move along the sixth guide rail in the Y-axis direction.

[0082] In this technical solution, the position of the base 15 is adjusted by setting a sixth guide rail and a first driving component 1 on the third mounting bracket. When adjustment begins, since the tube frame 19 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 far, the tube frame 19 and the second side plate 23 cannot be effectively adjusted. At this time, the first driving component 1 is used to drive the base 15 to move along the sixth guide rail in the Y-axis direction, that is, the base 15 moves closer to the second mounting bracket, so that the X-axis, Z-axis, and angle adjustment mechanism move closer to the tube frame 19 and the second side plate 23, ensuring normal adjustment of the tube frame 19 and the second side plate 23. All driving components in this application are pneumatic cylinders or electric cylinders.
