Description

Technical Field

[0001] The present invention relates to the technical field of assembly devices, and in particular to an automatic fin threading device. Background Art

[0002] Fins in air conditioners are connected to copper tubes to form the condenser or evaporator. This process of inserting the copper tubes into the fins is called fin threading. Fin threading is a crucial task in air conditioning plants, and currently, most factories perform this work entirely manually. This process is plagued by issues such as slow threading efficiency, high labor intensity, and high labor costs. Furthermore, fins are made of multiple layers of aluminum foil stacked together, which can easily cause misalignment of holes or slight deformation of the foil during handling. Furthermore, the long copper tubes are prone to deformation, making fin threading difficult.

[0003] Therefore, it is particularly important to provide a device that can realize automatic fin threading to improve production efficiency. Summary of the Invention

[0004] The problem solved by the present invention is the technical problem of slow sheet-threading efficiency, thereby achieving the technical effect of improving sheet-threading production efficiency.

[0005] In order to solve the above problems, the present invention provides an automatic fin threading device, comprising: a pipeline workbench, the pipeline workbench is provided with a pipeline positioning member, the pipeline positioning member is used to place the pipeline, and the pipeline positioning member is installed on the pipeline workbench through an elastic member; a fin workbench, the fin workbench is arranged opposite to the pipeline workbench, the fin workbench is used to place fins, and the fin workbench is provided with a first driving device for driving the fin workbench close to the pipeline workbench; a positioning device, the positioning device is arranged between the pipeline workbench and the fin workbench, and the positioning device includes a pipeline guide pin and a second driving device; wherein, under the second driving device, one end of the pipeline guide pin is inserted into the pipe mouth of the pipeline, and under the drive of the first driving device, the assembly hole of the fin is close to the pipe mouth, so that the other end of the pipeline guide pin is inserted into the assembly hole, and under the guidance of the pipeline guide pin, the pipeline is inserted into the fin.

[0006] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: the pipeline operation station and the fin operation station of the equipment are relatively arranged, and the two are in the same position, which avoids the waste of working hours caused by employees walking around when the operation stations are not in the same position, saves more time, and improves work efficiency. It also reduces the labor intensity of employees. Only one person is needed to operate the equipment to complete the workload of three people, which further improves work efficiency. On the other hand, a piece of fin threading equipment plus material turnover occupies about 7 square meters of space. The average manual threading station occupies 5.5 square meters, and 3 stations occupy 16.5 square meters. Each piece of fin threading equipment reduces the area occupied by 9.5 square meters. Therefore, the automatic fin threading equipment provided in this embodiment can reduce the area occupied by the workshop. The equipment can also complete the automatic threading operation of the fins. The pipeline guide pin follows the second drive device to move to the pipe mouth where the pipeline is inserted. Driven by the first drive device, the fin workbench moves toward the pipeline workbench, and the fin moves toward the pipeline guide pin on the pipe mouth until the other end of the pipeline guide pin is inserted into the fin. The fin workbench continues to move until the pipeline can smoothly pass through the fin. The pipeline guide pin has a guiding and positioning function throughout the threading process, making the automatic threading operation simpler, faster and more reliable, and only one person is required to operate the equipment to complete the operation. The first drive device and the second drive device drive the workbench to move, reducing labor costs and saving time and effort.

[0007] In an embodiment of the present invention, the elastic member is an elastic hinge, one end of the elastic hinge is connected to the bottom plate of the pipeline workbench, and the other end of the elastic hinge is connected to the pipeline positioning member.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting an elastic hinge, one end of the elastic hinge is connected to the bottom plate of the pipeline workbench, and the other end of the elastic hinge is connected to the pipeline locating piece. The elastic hinge has a certain folding flexibility, and then the pipeline locating piece can be folded in half with the bottom plate to achieve avoidance. The elastic hinge structure is reliable, not easy to damage, and can be folded in half repeatedly. During the movement of the fin workbench on the pipeline workbench, the pipeline locating piece can avoid, allowing the fin workbench to move back and forth on the pipeline workbench, and the pipeline locating piece can be quickly reset, so that the fin threading process is simpler and more efficient, without consuming manpower, and the pipeline can be quickly passed through the fin, thereby improving production work efficiency.

[0009] In one embodiment of the present invention, the pipeline guide pin is spindle-shaped.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that the shape and size of the pipeline guide pin are compatible with the pipe nozzle and the assembly hole of the fin. The two ends of the pipeline guide pin are pointed, which enables the pipeline guide pin to quickly position the pipeline and fin. Therefore, the two ends of the pipeline guide pin are more easily inserted into the pipe nozzle and the assembly hole of the fin, improving the efficiency of the fin insertion operation. It also has a guiding effect, guiding the pipeline to completely pass through the fin, further improving the efficiency and accuracy of the fin insertion operation. Therefore, even if the holes of the fin aluminum foil are misaligned or deviated during the stacking process, it will not affect the fin insertion operation.

[0011] In one example of the present invention, the positioning device also includes: a fixing part, the fixing part includes: a guide pin fixing seat connecting block, a pipeline guide pin fixing seat is provided on the side of the guide pin fixing seat connecting block close to the pipeline workbench, the pipeline guide pin is installed on the pipeline guide pin fixing seat, and the pipeline guide pin fixing seat is fixedly connected to the guide pin fixing seat connecting block.

The operation does not consume manpower, saves time and effort, and ensures the accuracy of the pipeline guide pin positioning, thereby improving the subsequent fin insertion efficiency.

[0013] In one embodiment of the present invention, the second driving device includes: a cylinder; a guide rod, the cylinder is connected to the guide rod, and the guide rod is connected to the guide pin fixing seat connecting block, so that the cylinder drives the guide pin fixing seat connecting block to move up and down.

[0014] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the pipeline guide pin is installed on the guide pin fixing seat connecting block through the pipeline guide pin fixing seat, and the up and down movement of the pipeline guide pin can be controlled by the cylinder, which saves time and effort, and quickly realizes the coaxiality of the pipeline guide pin and the pipe mouth of the pipeline, and the pipeline guide pin can be accurately assembled and connected with the pipe mouth of the pipeline, thereby improving the accuracy and efficiency of the piece insertion.

[0015] In one embodiment of the present invention, the positioning device further comprises: a suction cup connected to the pipeline guide pin fixing seat, and the suction cup is used to guide the pipeline guide pin to exit the fin and the pipeline.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: after the pipeline guide pin is connected to the pipeline guide pin fixing seat, the suction cup has an attraction to the pipeline guide pin, and can pull the pipeline guide pin out from the pipe mouth of the pipeline, so that the pipeline guide pin exits the fin and the pipeline, and the suction cup can guide the movement of the pipeline guide pin, and then the pipeline guide pin fixing seat can position and fix the pipeline guide pin more accurately, so that it can be quickly reset and used for the next penetration operation, realizing the cyclic operation of the penetration operation and improving the production work efficiency of the penetration.

When the fixed plate moves on the first guide rail toward the direction close to the pipeline workbench, the pipeline guide pin can be inserted into the pipe mouth; when the fixed plate moves on the first guide rail toward the direction away from the pipeline workbench, the pipeline guide pin can be pulled out of the pipe mouth, and the pulled out pipeline guide pin 131 is fixed in the pipeline guide pin fixing seat and can be used for the next insertion operation, so that the insertion operation can be circulated, and the production cost is further reduced.

[0019] In one embodiment of the present invention, the device further comprises: a second guide rail, which is provided on both sides of the pipeline workbench and the fin workbench, and the fin workbench slides back and forth on the second guide rail so that the pipeline is inserted into the fin.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] See also Figure 1 The present invention provides a fin automatic threading device 100, comprising: a pipeline workbench 110, the pipeline workbench 110 is provided with a pipeline positioning member 111, the pipeline positioning member 111 is used to place the pipeline 10, and the pipeline positioning member 111 is installed on the pipeline workbench 110 through an elastic member 112; a fin workbench 120, the fin workbench 120 is arranged opposite to the pipeline workbench 110, the fin workbench 120 is used to place the fin 20, and the fin workbench 120 is provided with a first driving device for driving the fin workbench 120 close to the pipeline workbench 110 Position 121; positioning device 130, positioning device 130 is arranged between pipeline workbench 110 and fin workbench 120, positioning device 130 comprises pipeline guide pin 131 and second driving device 132; wherein, under the second driving device 132, one end of pipeline guide pin 131 is inserted into the pipe mouth of pipeline 10, and under the drive of first driving device 121, the assembly hole of fin 20 is close to the pipe mouth, so that the other end of pipeline guide pin 131 is inserted into the assembly hole, and under the guidance of pipeline guide pin 131, pipeline 10 is inserted into the fin 20.

[0034] Specifically, the equipment 100 includes a main frame 101 , and a pipe workbench 110 and a fin workbench 120 are installed on the main frame 101 .

[0035] Specifically, the pipeline operation station and the fin operation station of the equipment 100 are in the same position, which avoids the waste of working hours caused by employees walking around when the operation stations are not in the same position, saves more time, and improves work efficiency. It also reduces the labor intensity of employees. Only one person is needed to operate the equipment to complete the workload of three people, which further improves work efficiency. On the other hand, a piece of sheet-threading equipment plus material turnover occupies about 7 square meters of space. The average manual sheet-threading station occupies 5.5 square meters, and 3 stations occupy 16.5 square meters. Each piece of sheet-threading equipment reduces the area occupied by 9.5 square meters. Therefore, the automatic fin threading equipment 100 provided in this embodiment can reduce the area occupied by the workshop.

[0036] Specifically, the pipeline 10 is a U-shaped copper tube, which is neatly arranged and placed on the pipeline positioning member 111. There are card slots on both sides of the pipeline positioning member 111, which can limit the U-shaped tube on the pipeline positioning member 111 to prevent the U-shaped tube from falling.

[0037] In a specific embodiment, the device 100 is powered on and started. Driven by the first drive device 121, the fin workbench 120 moves toward the pipeline workbench 110. Since the pipeline positioning member 111 is installed on the pipeline workbench through the elastic member 112, the pipeline positioning member 111 can avoid during the movement of the fin workbench 120. The fin workbench 120 applies pressure to the pipeline positioning member 111, and the pipeline positioning member 111 folds downward so that the fin workbench 120 passes through the pipeline positioning member 111 until the fin workbench 120 is pushed onto the pipeline workbench 110. The device 100 is paused, the fin 20 is placed on the fin workbench 120, and then the start button is pressed. The first drive device 121 drives the fin workbench 120 to return. After the fin workbench 120 leaves the pipeline workbench 110, the pipeline positioning member 111 is reset. The fin workbench 120 is pushed onto the pipe workbench 110 so that the fin workbench 120 and the pipe workbench 110 are pre-positioned, and then the fin 20 is placed on the fin workbench 120, so that the subsequent threading operation is more accurate and precise, avoiding deviations during the assembly process.

[0038] After the fin workbench 120 is reset, the equipment is paused and the U-shaped tube is placed on the pipeline positioning member 111. Press the automatic button, and under the drive of the second drive device 132, the pipeline guide pin 131 moves toward the pipe mouth of the U-shaped tube. The pipe mouth of the U-shaped tube is coaxial with the pipeline guide pin 131, and one end of the pipeline guide pin 131 can be smoothly inserted into the pipe mouth of the U-shaped tube. Driven by the second drive device 132, the positioning device 130 returns and resets. Driven by the first drive device 121, the fin workbench 120 moves toward the pipe workbench 110, and the assembly hole of the fin 20 is close to the pipe mouth of the U-shaped tube. At this time, the pipe mouth has been inserted into the pipeline guide pin 131, and then the other end of the pipeline guide pin 131 is inserted into the assembly hole. Under the guidance of the pipeline guide pin 131, the fin workbench 120 moves until the U-shaped tube passes through the fin 20, and the piercing operation is basically completed. Driven by the second driving device 132, the pipeline guide pin 131 is brought out of the two, and the brought out pipeline guide pin 131 can be used for the next fin threading. The fin 20 with the U-shaped tube installed is removed, and the cycle of the assembly work of the entire device 100 is completed.

[0039] It can be clearly seen that the pipeline guide pin 131 is adapted to the pipe opening of the U-shaped tube and the assembly hole of the fin 20 , and the pipeline guide pin 131 can smoothly pass through the interior of the fin 20 .

[0040] The pipeline guide pin 131 follows the second drive device 132 to move to the pipe mouth where the pipeline is inserted. Driven by the first drive device, the fin workbench 120 moves toward the pipeline workbench 110, and the fin 20 moves toward the pipeline guide pin 131 on the pipe mouth until the other end of the pipeline guide pin 131 is inserted into the fin 20. The fin workbench 120 continues to move until the pipeline 10 can smoothly pass through the fin 20. The pipeline guide pin 131 provides guidance and positioning throughout the entire fin threading process, making the automatic fin threading operation simpler, faster and more reliable, and only one person is required to operate the equipment to complete the operation. The first drive device 121 and the second drive device 132 drive the workbench movement, reducing labor costs and saving time and effort.

[0041] Example 2:

[0042] Based on Example 1, see Figure 1 and Figure 3 The elastic member 112 is an elastic hinge, one end of the elastic hinge is connected to the bottom plate 113 of the pipeline workbench 110, and the other end of the elastic hinge is connected to the pipeline positioning member 111.

[0043] Specifically, driven by the first driving device 121, the fin workbench 120 moves toward the pipeline workbench 110. When the fin workbench 120 moves onto the pipeline positioning member 111, the elastic hinge on the pipeline positioning member 111 will fold toward the elastic hinge on the bottom plate 113, thereby avoiding the movement of the fin workbench 120.

[0044] Furthermore, the fin workbench 120 moves onto the pipe workbench 110. Driven by the first drive device 121, the fin workbench 120 moves away from the pipe workbench 110. At this time, the elastic hinge on the pipe positioning member 111 resets in a direction away from the elastic hinge on the bottom plate 113. After the fin workbench 120 resets, the pipe positioning member 111 stands upright on the pipe workbench 110. Thus, the pipe 10 can be placed on the pipe positioning member 111.

[0045] By setting an elastic hinge, one end of the elastic hinge is connected to the bottom plate 113 of the pipeline workbench 110, and the other end of the elastic hinge is connected to the pipeline positioning member 111. The elastic hinge has a certain folding flexibility, and then the pipeline positioning member 111 can be folded with the bottom plate 113 to achieve avoidance. The elastic hinge structure is reliable, not easy to damage, and can be folded repeatedly. During the movement of the fin workbench 120 on the pipeline workbench 110, the pipeline positioning member 111 can avoid, so that the fin workbench 120 can move back and forth on the pipeline workbench 110, and the pipeline positioning member 111 can be quickly reset, so that the sheet-threading process is simpler and more efficient, does not consume manpower, and enables the pipeline 10 to quickly pass through the fin 20, thereby improving production work efficiency.

[0046] Example 3:

[0047] Based on Example 1, see Figure 1 The pipe guide pin 131 is spindle-shaped. The shape and size of the pipe guide pin 131 are compatible with the pipe opening of the pipe 10 and the assembly hole of the fin 20. The two ends of the pipe guide pin 131 are pointed, allowing the pipe guide pin 131 to quickly position the pipe 10 and the fin 20. The two ends of the pipe guide pin 131 are more easily inserted into the assembly holes of the pipe opening of the pipe 10 and the fin 20, improving the efficiency of the sheet insertion operation. It also has a guiding effect, guiding the pipe 10 to completely pass through the fin 20, further improving the efficiency and accuracy of the sheet insertion operation. Therefore, even if the aluminum foil of the fin 20 has misaligned holes or deviations during the stacking process, it will not affect the sheet insertion operation.

[0048] Example 4:

[0049] Based on Example 1, see Figure 1 and Figure 2 The positioning device 130 also includes: a fixing part 140, the fixing part 140 includes: a guide pin fixing seat connecting block 141, a pipeline guide pin fixing seat 142 is provided on the side of the guide pin fixing seat connecting block 141 close to the pipeline workbench 110, the pipeline guide pin 131 is installed on the pipeline guide pin fixing seat 142, and the pipeline guide pin fixing seat 142 is fixedly connected to the guide pin fixing seat connecting block 141.

[0050] Specifically, the positioning device 130 is provided with a positioning device fixing frame 30 , which plays a supporting role. The second driving device 132 is installed on the positioning device fixing frame 30 , making the structure more stable.

[0051] Specifically, the pipeline guide pin fixing seats 142 are neatly arranged on the guide pin fixing seat connecting block 141 , and the ports of the pipeline guide pin fixing seats 142 are adapted to the ports of the pipeline guide pins 131 .

[0052] Specifically, driven by the second driving device 132, the guide pin fixing seat connecting block 141 moves toward the direction close to the pipeline 10, and the pipeline guide pin 131 on the pipeline guide pin fixing seat 142 moves toward the pipe mouth of the pipeline 10 until the pipeline guide pin 131 toward one end of the pipe mouth is inserted into the pipe mouth. At this time, the pipeline guide pin 131 is separated from the pipeline guide pin fixing seat 142, and the other end of the pipeline guide pin 131 is used to connect to the assembly hole of the fin 20.

[0053] The pipeline guide pin 131 is installed on the pipeline guide pin fixing seat 142, and the connection is firm and reliable, which can prevent the pipeline guide pin 131 from falling during the movement of the positioning device 130, and the pipeline guide pin 131 follows the guide pin fixing seat connecting block 141 to move to the pipe mouth of the pipeline 10. The operation does not consume manpower, saves time and effort, and ensures the accuracy of the positioning of the pipeline guide pin 131, thereby improving the subsequent fin insertion efficiency.

[0054] Embodiment 5:

[0055] Based on Example 4, see Figures 1 to 3 The second driving device 132 includes: a cylinder 133; a guide rod 134, the cylinder 133 is connected to the guide rod 134, and the guide rod 134 is connected to the guide pin fixing seat connecting block 141, so that the cylinder 133 drives the guide pin fixing seat connecting block 141 to move up and down.

[0056] Specifically, the cylinder 133 is pressed downward, and the guide pin fixing seat connecting block 141 moves downward, so that the pipeline guide pin 131 is coaxial with the pipe opening of the pipeline 10. Driven by the second drive device 132, after the pipeline guide pin 131 is inserted into the pipe opening, the guide pin fixing seat connecting block 141 returns, that is, the guide pin fixing seat connecting block 141 moves in a direction away from the pipeline 10. During the return stroke, the blowing device provided at the guide pin fixing seat connecting block 141 blows air toward the pipeline guide pin 131 at the pipe opening to prevent the pipeline guide pin 131 from separating from the pipeline 10. After the guide pin fixing seat connecting block 141 returns, the cylinder 133 moves upward to reset, thereby preventing obstruction of the subsequent movement of the fin workbench 120.

[0057] The pipeline guide pin 131 is installed on the guide pin fixing seat connecting block 141 through the pipeline guide pin fixing seat 142. The up and down movement of the pipeline guide pin 131 can be controlled by the cylinder 133, which saves time and effort and quickly realizes the coaxiality of the pipeline guide pin 131 and the pipe mouth of the pipeline 10. The pipeline guide pin 131 can be accurately assembled and connected with the pipe mouth of the pipeline 10, thereby improving the accuracy and efficiency of the piece insertion.

[0058] Example 6:

[0059] Based on Example 5, see Figures 1 to 3The positioning device 130 also includes: a suction cup 135, which is connected to the pipeline guide pin fixing seat 142, and the suction cup 135 is used to guide the pipeline guide pin 131 to exit the fin 20 and the pipeline 10.

[0060] Specifically, the positioning device 130 includes a micro suction cup and hardware. Driven by the first drive device 121, the fin workbench 120 moves toward the pipeline workbench 110, and the assembly hole of the fin 20 passes through the other end of the pipeline guide pin 131, and the pipeline 10 is completely inserted through the fin 20. After the fin 20 is inserted into the pipeline 10, the cylinder 133 presses downward, so that the pipeline guide pin fixing seat 142 is coaxial with the assembly hole of the fin 20 after the fin 20 is inserted. Driven by the second drive device 132, the pipeline guide pin holder 142 is pushed to the nozzle of the pipeline 10, so that the pipeline guide pin 131 at the nozzle is inserted into the pipeline guide pin holder 142. At this time, the suction cup 135 draws air, and the pipeline guide pin holder 142 firmly holds the pipeline guide pin 131. The positioning device 130 returns, driving the pipeline guide pin holder 142 away from the nozzle, so that the pipeline guide pin 131 is disengaged from the nozzle of the pipeline 10. The suction cup 135 can guide the pipeline guide pin 131 out of the fin 20 and the pipeline 10. After the pipeline guide pin 131 is pulled out, the cylinder 133 moves upward, driving the guide pin holder connecting block 141 and the pipeline guide pin 131 back. The fin 20 assembled with the pipeline 10 is removed, completing the entire operation cycle of the equipment.

[0061] After the pipeline guide pin 131 is connected to the pipeline guide pin fixing seat 142, the suction cup 135 has an attraction to the pipeline guide pin 131, and can pull the pipeline guide pin 131 out of the pipe mouth of the pipeline 10, so that the pipeline guide pin 131 withdraws from the fin 20 and the pipeline 10, and the suction cup 135 can guide the movement of the pipeline guide pin 131, and then the pipeline guide pin fixing seat 142 can position and fix the pipeline guide pin 131 more accurately, so that it can be quickly reset and used for the next sheet-piercing operation, realizing the cyclic operation of the sheet-piercing operation, and improving the production efficiency of the sheet-piercing operation.

[0062] Embodiment seven:

[0063] Based on Example 5, see Figures 1 to 3 The positioning device 130 also includes: a first guide rail 136, a fixing plate 137 is provided on the first guide rail 136, the cylinder 133 is installed at the bottom of the fixing plate 137, and the fixing plate 137 can slide back and forth on the first guide rail 136 so that the pipeline guide pin 131 is inserted into the pipe mouth.

[0064] Specifically, the first guide rail 136 is mounted on the positioning device fixing frame 30 and is firmly connected. Driven by the motor of the second driving device 132, the fixing plate 137 slides on the first guide rail 136, so that the fixing plate 137 can move toward or away from the pipeline workbench 110.

[0065] For example, the cylinder 133 is pressed downward, and the guide pin fixing seat connecting block 141 moves downward, so that the pipeline guide pin 131 is coaxial with the pipe mouth of the pipeline 10. Driven by the motor, the fixing plate 137 moves along the first guide rail 136 toward the direction close to the pipeline workbench 110, and the cylinder 133 moves with the fixing part 137, and then the pipeline guide pin 131 is inserted into the pipe mouth.

[0066] Furthermore, the cylinder 133 moves upward and resets, and driven by the motor, the fixing plate 137 moves back in a direction away from the pipeline workbench 110, so that the positioning device 130 returns to its original position.

[0067] Furthermore, based on the sixth embodiment, after the fin 20 is inserted into the pipeline 10, the cylinder 133 is pressed downward, the guide pin fixing seat connecting block 141 moves downward, and the fixing plate 137, driven by the motor, moves along the first guide rail 136 toward the pipeline workbench 110 until the pipeline guide pin 131 at the pipe mouth is inserted into the pipeline guide pin fixing seat 142. The cylinder 133 moves upward and resets, and the pulled-out pipeline guide pin 131, driven by the motor, follows the fixing plate 137 back toward the pipeline workbench 110, returning the positioning device 130 to its original position.

[0068] The entry and exit of the pipeline guide pin 131 on the pipe mouth of the pipeline is controlled by moving the fixed plate 137 on the first guide rail 136. This is simple, efficient, easy to implement, and does not consume manpower. When the fixed plate 137 moves on the first guide rail 136 toward the direction close to the pipeline workbench 110, the pipeline guide pin 131 can be inserted into the pipe mouth; when the fixed plate 137 moves on the first guide rail 136 toward the direction away from the pipeline workbench 110, the pipeline guide pin 131 can be pulled out of the pipe mouth. The pulled-out pipeline guide pin 131 is fixed in the pipeline guide pin fixing seat 142 and can be used for the next insertion operation, so that the insertion operation can be circulated, and the production cost is further reduced.

[0070] Based on Example 1, see Figures 1 to 3 The device 100 also includes: a second guide rail 150, which is arranged on both sides of the pipeline workbench 110 and the fin workbench 120, and the fin workbench 120 slides back and forth on the second guide rail 150 so that the pipeline 10 is inserted into the fin 20.

[0071] By controlling the moving distance and direction of the fin workbench 120 on the second guide rail 150, the fin workbench 120 can quickly reach the pipe workbench 110, which is more efficient and quickly completes the insertion operation of the pipe 10 into the fin 20. At the same time, the sliding process is smooth, does not consume manpower, and saves time and effort.

[0072] Embodiment 9:

[0073] Based on Example 1, see Figure 1 The pipeline workbench 110 also includes a pipeline positioning tool 114, which is fixed to the pipeline workbench 110 through positioning pins. The pipeline positioning tool 114 is used to limit the pipeline 10.

[0074] Specifically, the baffle of the pipeline positioning tool 114 protrudes a certain distance toward the fin workbench 120, and the protruding portion can further limit the pipeline 10, so that the pipeline 10 placed on the pipeline positioning member 111 is not easy to fall off, and prevents the pipe mouth of the pipeline 10 from being inserted into the wrong hole. And when the fin workbench 120 moves to the baffle of the pipeline positioning tool 114, the fin workbench 120 is limited to ensure the accuracy of positioning. The pipeline positioning tool 114 is fixed to the pipeline workbench 110 by screws and positioning pins to ensure the positioning accuracy of the pipeline positioning tool 114. The pipeline positioning tool 114 of different models of air conditioners is different, so the installation position of the pipeline positioning tool 114 on the pipeline workbench 110 can be adjusted according to the specific situation, which is more universal.

[0075] Embodiment 10:

[0076] Based on Example 1, see Figure 1 The fin workbench 120 also includes a fin positioning tool 122 , which is fixed to the fin workbench 120 through a positioning pin. The fin positioning tool 122 is used to limit the fin 20 .

[0077] Specifically, the fin positioning fixture 122 is provided with limit plates, which are arranged on both sides of the fin 20 to limit the fin 20 and prevent it from shifting, making the fin threading operation smooth and fast. The fin positioning fixture 122 is fixed to the fin workbench 120 by screws and positioning pins, ensuring the positioning accuracy of the fin positioning fixture 122. The fin positioning fixture 122 of different air conditioner models is different, so the installation position of the fin positioning fixture 122 on the fin workbench 120 can be adjusted according to the specific situation, making it more universal.

[0078] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
