Description

Technical Field

[0001] This utility model relates to the technical field of automatic copper pipe threading equipment, and in particular to an automatic copper pipe threading equipment for air conditioner heat exchangers. Background Technology

[0002] Air conditioner components, including the heat exchanger and refrigerant unit, achieve heating or cooling effects through refrigerant circulation. The air conditioning system utilizes the refrigerant's repeated flow within the refrigerant circuit, exchanging heat through processes such as evaporation, compression, condensation, and expansion to regulate indoor temperature. To achieve this, a refrigerant circulation loop unit must be designed and established, typically consisting of multiple refrigerant loops.

[0003] Currently, existing technologies generally employ the method of inserting copper tubes into aluminum fins and connecting multiple copper tubes through a unidirectional bending opening design. This design facilitates the insertion and positioning of the copper tubes, allowing the refrigerant to flow efficiently within the condenser. The specific process involves inserting the copper tubes into the openings of the aluminum fins and using a series of mechanical processes, such as bending, welding, or fixing, to create a stable heat exchange interface between the copper tubes and the fins. This process ensures that each copper tube is in close contact with multiple aluminum fins, thereby improving heat exchange efficiency.

[0004] Because condenser components typically consist of multiple refrigerant circuit units, with a large number of densely packed copper tubes, the copper tube configuration throughout the process requires high precision. To meet design requirements, the internal copper tube arrangement of the condenser features multiple tubes arranged side-by-side in a compact space, leading to a technical challenge: the copper tube installation process demands high accuracy and is labor-intensive. Due to the large number and close proximity of the copper tubes, the current copper tube installation process is entirely manual, resulting in a cumbersome, complex, and labor-intensive operation prone to errors and deviations. Furthermore, manual operation leads to higher production costs and greater labor input.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0042] The refrigerant and heat exchanger components of an air conditioner achieve heating or cooling effects through refrigerant circulation and are the core components of an air conditioning system. The working principle of an air conditioning system is based on the physical properties of the refrigerant. The refrigerant flows repeatedly in the refrigerant circuit, undergoing processes such as evaporation, compression, condensation, and expansion to gradually complete heat exchange and ultimately regulate indoor temperature. Specifically, the refrigerant absorbs heat at low temperature and low pressure through the evaporator, becomes gaseous, is compressed to a high temperature and high pressure by the compressor, then releases heat through the condenser, and finally enters the evaporator through the expansion valve to continue absorbing heat. The core of this process is the circulation of the refrigerant, and to efficiently complete heat exchange, an efficient refrigerant circulation loop unit must be designed and established.

[0043] As part of the refrigerant circulation loop, the condenser component typically consists of multiple refrigerant loop units. Each loop includes copper tubes and aluminum fins. The copper tubes carry the flowing refrigerant, while the aluminum fins increase the surface area for heat exchange, helping to dissipate excess heat. In existing manufacturing processes, the copper tubes usually need to be inserted into the aluminum fins. This process typically involves inserting multiple copper tubes into openings in the aluminum fins and connecting them using a unidirectional bending method. A stable heat exchange interface can be formed between the copper tubes and the aluminum fins, ensuring efficient refrigerant flow and heat exchange performance.

[0044] During copper tube installation, tight contact between the copper tubes and aluminum fins is crucial for heat exchange efficiency. Since each condenser component consists of multiple copper tubes, each tube requires extremely precise placement, and the internal configuration of the copper tubes in the condenser is typically multi-tube, closely spaced arrangement. Therefore, the insertion, fixing, and connection of the copper tubes throughout the process demands extremely high precision. However, due to the large number of copper tubes and their relatively close proximity, current processes still rely entirely on manual labor for all copper tube installation and insertion. This operation is not only complex and tedious but also requires highly skilled workers to ensure precise fit between the copper tubes and fins; otherwise, errors can easily occur, affecting the condenser's heat exchange performance.

[0045] Another problem with manual operation is its high labor intensity. Due to the large number and dense arrangement of copper tubes in the condenser, workers need to perform repetitive operations for extended periods. This not only increases labor costs but also easily leads to worker fatigue, thus affecting production efficiency and product quality. Furthermore, manual operation itself carries a significant risk of production deviations, such as errors in the bending angle or position of the copper tubes. These deviations can result in poor sealing of the refrigerant circuit, consequently affecting the condenser's heat exchange performance and the overall stability of the system.

[0046] Therefore, improving the precision of the copper tube insertion process, reducing manual intervention, and simultaneously increasing production efficiency and reducing production costs are major technical challenges in the current manufacturing process of air conditioning heat exchanger components. To address this challenge, automation technology, intelligent production processes, precision equipment, and accurate control systems have become key technological directions.

[0047] The present invention will now be further described in conjunction with the accompanying drawings and embodiments: Figure 1 The automatic copper tube insertion device for air conditioners includes a copper tube gripping component 1, a conveyor line component 2, a condenser positioning component 3, fins 4, a rake plate component 5, a copper tube guiding component 6, a copper tube pushing component 7, a copper tube cart component 8, and a traveling component 9. The conveyor line component 2 and the traveling component 9 are synchronous conveyor lines. The copper tube gripping component 1 is located on one side of the traveling component 9. The condenser positioning component 3, the rake plate component 5, the copper tube guiding component 6, and the copper tube pushing component 7 are synchronous tube insertion components. The copper tube gripping component 1 grips the condenser copper tube 804 onto the traveling component 9. The synchronous tube insertion components position the condenser and the condenser copper tube 804 on the conveyor line component 2 and the traveling component 9 and insert the condenser copper tube 804 into the condenser.

[0048] The system utilizes a synchronous conveyor line, a copper tube gripping mechanism, and synchronous tube threading components to achieve synchronized material flow and copper tube threading during the condenser threading process. It is equipped with high-precision copper tube positioning components, condenser positioning components, and a combined copper tube and condenser positioning component to achieve high-precision positioning of components during the automated tube threading process.

[0049] As one embodiment of this utility model, such as Figure 2 As shown, the copper pipe gripping component 1 includes a gripping robot 102, which is mounted on a robot mounting base 101. The flange of the gripping robot 101 is provided with a copper pipe clamp mounting plate 103. The copper pipe clamp mounting plate 103 is provided with a plurality of gripping cylinders 104. The gripping cylinders 104 are connected to servo grippers 105. The output end of the servo grippers 105 is provided with two symmetrical and parallel copper pipe mounting plates 106.

[0050] Furthermore, the gripping cylinders 104 are arranged in a horizontal array of 2 rows and 14 columns, and the mounting end of the gripping cylinders 104 is directly connected and fixed to the bottom surface of the copper pipe clamp mounting plate 103.

[0051] The position and number of the copper tube clamps 106 correspond to the positions of the copper tubes to be inserted on the condenser.

[0052] As one embodiment of this utility model, such as Figure 3-4As shown, the conveyor line component 2 is a belt conveyor line. The condenser positioning component 3 is installed on the conveyor line component 2. Six groups of condenser positioning components 3 are arranged horizontally. Each condenser positioning component 3 consists of two condenser positioning blocks 301 symmetrically installed. A condenser positioning connecting plate 302 passes through screw holes and is fixed to the conveyor line component 2. The conveyor line component 2, in conjunction with the condenser positioning components 3, conveys both the un-pipe condenser 401 and the piped condenser 402.

[0053] The belt conveyor component 2 efficiently transports condensers, ensuring continuous flow and precise positioning within the production line. The belt conveyor design allows for smooth and stable transport of condensers throughout the production process. The installation of the condenser positioning component 3 on the conveyor ensures accurate alignment and positioning of the un-tubed condenser 401 and the tubed condenser 402 during production. Six sets of horizontally aligned condenser positioning components 3 ensure even distribution of multiple condensers during transport and effectively prevent lateral displacement, avoiding subsequent processing problems caused by inaccurate positioning. The combination of the conveyor system and the condenser positioning components flexibly addresses the different process requirements of un-tubed and tubed condensers. During transport, the positioning components ensure that the un-tubed condenser is in the correct position for subsequent tube-insertion operations.

[0054] As one embodiment of this utility model, such as Figure 5 As shown, the rake plate component 5 includes a rake plate mounting frame 501, a rake plate cylinder 502, a rake plate upper plate 503, a rake plate lower plate 505, and a cylinder connecting plate 504. The rake plate component 5 uses the rake plate mounting frame 501 as a mounting base. The lower fixing seat of the rake plate mounting frame 501 is fixed to one end of the component mounting plate 905 near the conveyor line component 2 by screw connection. Two rake plate cylinders 502 are symmetrical about the center face of the rake plate mounting frame 501 and are fixed to the upper part of the rake plate mounting frame 501 through screw holes. The output end of the rake plate cylinder 502 is connected to the upper surface of the cylinder connecting plate 504. The side of the cylinder connecting plate 504 is aligned and overlapped with the upper end face of the rake plate upper plate 503 and fixed. The lower surface of the cylinder connecting plate 504 of the rake tooth plate lower plate 505 is fixedly installed on the component mounting plate 905 by means of screw holes, and the side of the cylinder connecting plate 504 is fixedly connected to the mounting end of the rake tooth plate cylinder 502.

[0055] The mounting bracket's fixing method ensures the overall stability of the rake tooth plate component, preventing displacement or loosening due to vibration or external forces during operation. The rake tooth plate mounting bracket 501 is fixed to the component mounting plate 905 via screw connections, ensuring the structural robustness of the entire assembly. Two symmetrically arranged rake tooth plate cylinders 502 ensure even force distribution throughout the entire rake tooth plate component during operation, thereby improving operational stability and precision. The cylinder-controlled rake tooth plate component can accurately and quickly complete material transfer and sorting tasks. The efficient pneumatic control system enables continuous, high-speed material handling during production line operation.

The un-tubed condenser 401 needs to be placed on the conveyor line component 2 to ensure that the un-tubed condenser 401 and the condenser positioning component 3 are correctly matched and that the un-tubed condenser 401 flows normally on the conveyor line component 2. The condenser copper tubes 804 need to be sorted and placed in the copper tube cart component 8 in advance to ensure that the materials are sufficient.

[0064] When the equipment is powered on and started, the copper pipe gripping component 1 returns to the Home point to wait, and the conveyor component 2 pauses. The copper pipe cart component 8 is placed in position, and the walking component 9, servo motor 908, moves to transmit kinetic energy to the gear and rack group 904 through right-angle reducer 907, driving the component mounting plate 905 to move to the origin point close to the copper pipe cart component 8. During the return of the walking component 9 to the origin point, the rake plate cylinders in the upper and lower parts of the rake plate component 5 retract, driving the upper plate 503 and lower plate 505 of the rake plate to open. The linear module 609 in the copper pipe guide component 6 moves, and the cylinder mounting seat 603 moves from the center of the component mounting plate 905 to the origin point of the linear module 609 simultaneously in two directions, left and right, through the sliding block of the linear module 609. During the retraction, the second guide plate cylinder 608 retracts and the first guide plate cylinder 606 extends, and the copper pipe guide component 6 returns to the initial state. In the copper tube propulsion component 7, the sliding block of the linear module 609 drives the copper tube propulsion cylinder mounting base 703 to retract to the origin. During the retraction process, the copper tube propulsion cylinder 702 retracts, and the copper tube propulsion component 7 is in its initial state.

[0065] The equipment has returned to zero, and conveyor line component 2 begins operation. The un-pipe condenser 401 begins to move at a constant speed from right to left on conveyor line component 2. Simultaneously, the gripping robot 102 moves the copper pipe clamp mounting plate 103 to the gripping point of the condenser copper pipe 804. During the movement of the gripping robot 102, the gripping cylinder 104 extends, and the servo gripper 105 drives the copper pipe clamping plate 106 to open. The gripping robot 102 stops at the gripping point of the condenser copper pipe 804, and the servo gripper 105 drives the copper pipe clamping plate 106 to clamp, gripping the condenser copper pipe 804. 02. Once the robot moves to a position directly above the origin of the walking component 9, it continues to move. Simultaneously, the copper tube propulsion cylinder 702 extends until the condenser copper tube 804 is placed in the groove of the copper tube propulsion plate 701. The gripping robot 102 then pauses. The linear module 609 in the copper tube guide component 6 moves, and the cylinder mounting seat 603 is driven by the sliding block of the linear module 609 to move simultaneously from the left and right directions toward the center surface of the component mounting plate 905. Once in position, the second guide plate cylinder 608 extends and the first guide plate cylinder 606 retracts, and the copper tube guide component 6 is in a clamped state (the left and right sets of actions are the same, but in opposite directions). Wait for the un-pipe condenser 401 to move at a constant speed from right to left on the conveyor line component 2 to the pipe insertion starting point. After the un-pipe condenser 401 moves into place, the rake plate cylinder 502 in the upper and lower parts of the rake plate component 5 is pushed out, and the upper plate 503 and the lower plate 505 of the rake plate clamp together, simultaneously clamping the condenser copper tube 804 and the un-pipe condenser 401. The servo gripper 105 drives the copper tube clamping plate 106 to open, and the gripping cylinder 104 retracts. The gripping robot 102 first retracts to the condenser copper tube 804 gripping waiting point.During the retraction of the gripping robot 102, the conveyor component 2 and the walking component 9 move simultaneously at synchronized speeds. The servo motor 908 transmits kinetic energy to the gear and rack assembly 904 via the right-angle reducer 907, driving the component mounting plate 905 and the un-pipe condenser 401 to move uniformly from right to left on the conveyor component 2 in the same direction. During the movement, the sliding block of the linear module 609 in the copper pipe pushing component 7 drives the copper pipe pushing cylinder mounting seat 703 forward. When the first pushing point is reached, the linear module 609 in the first group of copper pipe guiding components 6 moves, driving the cylinder mounting seat 603 from the center of the component mounting plate 905 to the origin of the linear module 609 simultaneously from the left and right directions. When the second pushing point is reached, the linear module 609 in the second group of copper pipe guiding components 6 moves, driving the cylinder mounting seat 603 from the center of the component mounting plate 905 to the left and right directions simultaneously. Simultaneously retracting in both directions to the origin of the linear module 609, the copper tube propulsion component 7 continues to advance. The sliding block of the linear module 609 drives the copper tube propulsion cylinder mounting base 703 forward. After the copper tube propulsion component 7 approaches the edge of the rake tooth plate component 5, the copper tube propulsion component 7 activates, and the sliding block of the linear module 609 drives the copper tube propulsion cylinder mounting base 703 backward. When the tail of the condenser copper tube 804 is tangent to the copper tube propulsion plate 701, the sliding block of the linear module 609 pauses, and the copper tube propulsion... When the intake cylinder 702 retracts, the copper tube propulsion component 7 actuates. The sliding block of the linear module 609 drives the copper tube propulsion cylinder mounting base 703 forward until the tail of the condenser copper tube 804 is about 2cm from the edge of the rake plate component 5. The copper tube propulsion component 7 then pauses, and the sliding block of the linear module 609 drives the copper tube propulsion cylinder mounting base 703 backward, bringing the copper tube propulsion component 7 back to its origin and waiting. The copper tube propulsion component 7 is in its initial state (this process is the same as the zeroing process of the copper tube propulsion component 7). During the process of the copper tube propulsion component 7 returning to its origin, the rake plate cylinder 502 in the upper and lower parts of the rake plate component 5 retracts, and the upper plate 503 and lower plate 505 of the rake plate open, bringing the rake plate component 5 to its initial state. During the process of the copper tube propulsion component 7 moving to the origin, the walking component 9 moves, and the servo motor 908 moves to transmit kinetic energy to the gear and rack group 904 through the right angle reducer 907, which drives the component mounting plate 905 to move to the right to the origin. The equipment completes one cycle, and subsequent cycles are the same as the first cycle, until the copper tube condenser copper tube 804 of the copper tube cart component 8 is used up and the equipment stops.

[0066] The main functions of this utility model are:

[0067] By designing a synchronous conveyor line, copper tube gripping components, and synchronous tube threading components, seamless synchronization of material flow and tube threading between the condenser and copper tubes during the threading process is achieved, improving production line continuity and equipment utilization, and avoiding downtime and waiting time. Furthermore, dedicated high-precision positioning components ensure accurate positioning of the copper tubes and condenser, avoiding errors and deviations, and improving heat exchange efficiency and equipment stability. The use of servo grippers and industrial robot control enables efficient gripping and precise positioning of large quantities of copper tubes at multiple locations, significantly reducing worker workload and operational errors.
