Description

Technical Field

[0001] This invention relates to the field of air conditioning parts technology, and more specifically, to an automatic welding equipment for air conditioning parts. Background Technology

[0002] Air conditioning piping is a component that connects the entire refrigeration system. These piping systems are responsible for connecting core components such as the compressor, condenser, throttling device, and evaporator in series into a closed loop, ensuring that the refrigerant can flow safely and efficiently within it to achieve heat absorption and release. To ensure performance and energy efficiency, the piping system has extremely high requirements for sealing and is often wrapped with insulation material to prevent energy loss and condensation.

[0003] Currently, welding is one of the key connection processes in the manufacturing of air conditioning parts, especially for components involving piping systems. The quality of welding directly affects the sealing, durability, and performance stability of the entire unit. Precise positioning and stability are required during welding, and protective gas is also needed to prevent high-temperature oxidation.

[0004] However, existing welding methods typically involve directly fixing the bottom of the air conditioning component pipes and then inserting the parts to be welded onto the air conditioning component. This can lead to defects such as incomplete welds and misalignments due to positioning deviations or unstable clamping during the welding process, thus affecting product yield.

[0005] Therefore, the present invention proposes an automatic welding device for air conditioning parts. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic welding equipment for air conditioning parts.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic welding device for air conditioning parts includes a fixed base, a clamping fixture, a welding positioning component disposed on the fixed base, and a feeding component disposed on the side of the fixed base. A feeding component is installed on one side of the feeding component, and a conveying component is disposed on one side of the feeding component. The welding positioning component includes a heating mechanism, a cooling mechanism, and an air intake mechanism. The heating mechanism includes a slide groove, a drive motor is fixed to one end of the slide groove, and the output end of the drive motor is inserted into the slide groove and connected to a threaded rod. A slider is adapted to be disposed on the threaded rod, a connecting rod is fixed below the slider, a heating wire is fixed on the connecting rod, and a clamping mechanism is installed on the slider.

[0009] The present invention is further configured such that: the clamping mechanism includes a slide block, the slide block is fixed on the slider, a first slide rod is slidably disposed on the slide block, a clamping seat is mounted on the first slide rod, a clamping cylinder is mounted below the clamping seat, a clamping claw is mounted on the clamping cylinder, and a clamping groove is provided on the clamping claw.

[0010] The present invention is further configured such that: the welding positioning assembly further includes a fixing column, a first cylinder is symmetrically arranged on the fixing column, an installation platform is installed at the output end of the two first cylinders, a displacement plate is installed on the installation platform, an electric slide rail is provided on the displacement plate, the heating mechanism is fixed to the slider on the electric slide rail, the cooling mechanism is arranged on the side wall of the fixing column, and the air intake mechanism is fixed on the first fixing platform.

[0011] The present invention is further configured such that: the fixed base includes a first fixed platform, and a gas conveying device is provided on the first fixed platform.

[0012] The present invention is further configured such that: the inspection component includes a support leg, an inspection conveyor belt is fixed on the support leg, an electrical control module is installed below the inspection conveyor belt, a supplementary light is provided on one side of the inspection conveyor belt, and a camera is installed on the other side of the inspection conveyor belt.

[0013] The present invention is further configured such that: the conveying component includes rectangular support members, a chain drive belt is provided on every two support members, a fixed base plate is connected below the two chain drive belts, a second lifting cylinder is fixed on the fixed base plate, and a second conveying mechanism is installed on the second lifting cylinder.

[0014] The present invention is further configured such that: the second conveying mechanism includes a second conveying base plate, a plurality of second transmission wheels are rotatably disposed on the outer side of the second conveying base plate, and a second transmission belt is sleeved on the second transmission wheels on both sides.

[0015] The present invention is further configured such that: a second drive motor is installed in the middle of the second conveying substrate, a second drive tooth is installed at the output end of the second drive motor, a second drive shaft is connected between the two second drive wheels, and a second driven tooth is installed on the second drive shaft.

[0016] The present invention is further configured such that: the feeding assembly includes a feeding protective shell, a control block is provided on the side wall of the feeding protective shell, a first fixing plate is provided above the control block, a lifting limit block is installed below the first fixing plate, a lifting mechanism is provided below the lifting limit block, and a first conveying mechanism is provided on one side of the lifting mechanism.

[0017] A method of using an automatic welding equipment, comprising the above-described automatic welding equipment for air conditioning parts, including:

[0018] Step S1: Install the workpiece on the clamping fixture, place the clamping fixture on the feeding component, the feeding component moves the clamping fixture to the same height as the conveying component, the feeding component moves the clamping fixture to the conveying component, and the conveying component transports the clamping fixture to the inspection component.

[0019] Step S2: The inspection component performs visual inspection on the workpiece on the clamping fixture to confirm the welding position. If the inspection result meets the preset standard, a signal is sent to the control system to start the welding positioning component for precise welding operation. If there is a deviation in the inspection, an alarm device will prompt manual intervention or automatically remove the workpiece.

[0020] Step S3: After receiving the signal, the welding positioning component moves the heating mechanism above the workpiece, drives the slider to move to the position where the fixed tube and the welding tube are inserted, and then the welding positioning component lowers the heating mechanism to the insertion position. At the same time, the clamping mechanism moves down to the position of the welding tube to clamp the welding tube, and the air inlet mechanism abuts against the clamping fixture.

[0021] Step S4: The gas inlet mechanism introduces protective gas into the welding pipe, while the heating mechanism heats the welding area evenly, so that the welding materials melt and bond together, and form a strong weld after cooling.

[0022] Step S5: After welding is completed, the clamping mechanism resets, the heating mechanism rises, the air supply mechanism stops supplying air, and the cooling mechanism forces the weld to cool the weld, ensuring rapid solidification of the welded area and reducing thermal deformation.

[0023] Step S6: After cooling, the inspection component performs a second visual inspection on the workpiece on the clamping fixture to confirm whether the weld quality meets the process requirements. If the inspection is qualified, the conveying component will transport the clamping fixture to the conveying component for unloading. If the inspection is unqualified, the defect location will be marked and an alarm will be triggered.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] The output of the drive motor rotates, causing the threaded rod to rotate. The slider moves along the slide groove under the drive of the threaded rod, positioning the clamping fixture and allowing the heating wire to move precisely to the welding area. At the same time, the clamping mechanism moves above the clamping fixture for welding clamping, achieving the effect of positioning and welding the clamping fixture. Attached Figure Description

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0052] Please see Figure 1-17 The present invention provides the following technical solutions:

[0053] Example

[0054] See Figure 3 and Figure 11 An automatic welding device for air conditioning parts includes a fixed base 1, a welding positioning component 2 disposed on the fixed base 1, and an inspection component 3 disposed on the side of the fixed base 1, a feeding component 4 disposed on one side of the inspection component 3, and a conveying component 5 disposed on one side of the feeding component 4, wherein the conveying component 5 holds a clamping fixture 6 to be processed.

[0055] The fixed base 1 provides an installation position for the welding positioning component 2. The fixed base 1 is equipped with a matching air and electrical system, and works with the inspection component 3 to detect the welding position of the air conditioning parts. The welding positioning component 2 performs precise welding on the air conditioning parts. The conveying component 5 transports the clamping fixture 6 to the loading component 4. The conveying component 5 lifts the clamping fixture 6 from the bottom to the height of the loading component 4 and delivers the clamping fixture 6 to the loading component 4. The loading component 4 then delivers the clamping fixture 6 to the inspection component 3, completing the transport of the clamping fixture 6. The inspection component 3 then moves the clamping fixture 6 to a position close to the welding positioning component 2. The welding positioning component 2 performs automatic welding operation on the clamping fixture 6.

[0056] The fixed base 1 includes a first fixed platform 11, on which a gas supply device 12 is installed. The interior of the first fixed platform 11 is hollow. The gas supply device 12 provides power support for the entire automatic welding equipment. The gas output is connected to each device through the gas supply device 12 to complete the gas supply. The power system is supplied to each actuator through lines to realize the synchronous coordination of electric drive and signal control.

[0057] See Figure 3 and Figure 5 The welding positioning assembly 2 also includes a fixing column 21, on which first cylinders 22 are symmetrically arranged. The output ends of the two first cylinders 22 are mounted on mounting platforms 23. On the mounting platforms 23, displacement plates 24 are mounted. On the displacement plates 24, electric slide rails 25 are provided. The heating mechanism 26 is fixed to the slider on the electric slide rails 25. A cooling mechanism 28 is provided on the side wall of the fixing column 21. An air intake mechanism 29 is also installed on the first fixing platform 11.

[0058] The bottom of the fixed column 21 is fixedly connected to the first fixed platform 11, and the top of the fixed column 21 provides support for two first cylinders 22. The fixed ends of the first cylinders 22 are mounted on the fixed column 21, and the output ends of the first cylinders 22 extend toward the working area. The mounting platform 23 moves synchronously with the extension and retraction of the first cylinders 22, causing the displacement plate 24 to move synchronously. The electric slide rail 25 includes a slide rail and a slider. The slide rail of the electric slide rail 25 is fixed to the displacement plate 24. The slider of the electric slide rail 25 is an electric slider. The electric slider of the electric slide rail 25 is displaced by a positioning system. The positioning system issues a movement command according to the welding position of the clamping fixture 6. The reciprocating motion of the slider drives the heating mechanism 26 to move and adjust along the slide rail direction to ensure that the heating mechanism 26 is accurately positioned to the welding starting point. The first cylinder 22 drives the mounting platform 23 to press down, causing the displacement plate 24 to move the heating mechanism 26 close to the surface of the clamping fixture 6. On the other hand, the electric slider of the electric slide rail 25 is finely adjusted to compensate for displacement error. The heating mechanism 26 is equipped with a clamping mechanism 27. When the heating mechanism 26 moves to the welding position, the clamping mechanism 27 clamps and positions the parts to be welded on the clamping fixture 6 to ensure that the clamping fixture 6 remains stable during the welding process and avoids weld point deviation due to vibration or displacement. The heating component on the heating mechanism 26 heats and welds the parts to be welded on the clamping fixture 6. After the welding is completed, the cooling mechanism 28 blows air to cool the welded parts, and the weld strength is improved after cooling. The air intake mechanism 29 is fixed on the first fixed platform 11. The air intake mechanism 29 includes a fixing part and an air supply pipe. When the clamping fixture 6 moves to the welding position, the air intake mechanism 29 introduces protective gas into the clamping fixture 6 to protect the inside of the welded part. The introduced gas is nitrogen to prevent internal oxidation during the welding process.

[0059] The inspection component 3 includes a support leg 35, an inspection conveyor belt 32 is fixed on the support leg 35, an electrical control module 33 is installed below the inspection conveyor belt 32, a supplementary light 31 is provided on one side of the inspection conveyor belt 32, and a camera 34 is installed on the other side of the inspection conveyor belt 32.

[0060] The support legs 35 support the conveyor belt 32 for inspection. The conveyor belt 32 includes a suspension for fixing, with the bottom of the suspension fixed to the support legs 35. Multiple rollers are arranged between the two suspensions. The rollers are rotated by an electronic control system. The electronic control module 33 controls the rotation of the rollers to achieve smooth transport of the clamping fixture 6. The camera 34 is used to detect the position of the clamping fixture 6. When the clamping fixture 6 reaches the designated position, the camera 34 sends a signal, and the rollers stop rotating to ensure accurate positioning of the clamping fixture 6. When the clamping fixture 6 reaches the designated position, the camera 34 determines the moving position of the clamping fixture 6 and locates the welding position, outputting position information. Meanwhile, supplementary lighting 31 provides supplementary lighting, making the welding position more clearly visible on camera 34, providing a position reference for subsequent welding operations. The electrical control module 33 is electrically connected to the control system, receives feedback signals from the sensors, and dynamically adjusts the roller speed to ensure stable and non-deviation-free conveying. Camera 34 can perform high-definition imaging of the welding area of ​​workpiece 7, capture the weld shape and position deviation in real time, and transmit the image data to the control system for analysis and comparison, and automatically adjust the movement trajectory of heating mechanism 26. At the same time, the system can identify surface defects of the weld point, such as porosity and cracks, during the detection process, trigger alarms and mark defective workstations.

[0061] See Figure 8 The feeding assembly 4 includes a feeding protective shell 41. A control block 42 is provided on the side wall of the feeding protective shell 41. A first fixing plate 43 is provided above the control block 42. A lifting limit block 44 is installed below the first fixing plate 43. A lifting mechanism 45 is provided below the lifting limit block 44. A first conveying mechanism 46 is provided on one side of the lifting mechanism 45. The lifting mechanism 45 is fixedly connected to the lifting limit block 44.

[0062] The loading protective shell 41 is used for support, and the internal space is used to accommodate the transmission path of the clamping fixture 6. The control block 42 controls the device inside the loading protective shell 41 to avoid sudden situations during operation. The first fixing plate 43 provides a fixed position for the lifting limit block 44. The lifting limit block 44 is fixed to the top of the loading protective shell 41 through the first fixing plate 43 to ensure structural stability. The lifting mechanism 45 works in conjunction with the lifting limit block 44. The lifting mechanism 45 drives the first conveying mechanism 46 to move upward, lifting the clamping fixture 6 away from the conveyor line. The lifting limit block 44 limits the lifting position of the lifting mechanism 45. When it is lifted to the position of the conveying component 5, the first conveying mechanism 46 is aligned with the conveying component 5 to ensure that the clamping fixture 6 accurately enters the next station. During the lifting process, the lifting limit block 44 restricts the movement trajectory of the lifting mechanism 45.

[0063] See Figure 9The conveying component 5 includes rectangular support members 51, with chain drive belts 52 on each pair of support members 51. A fixed base plate 53 is connected below the two chain drive belts 52. A second lifting cylinder 54 is fixed on the fixed base plate 53, and a second conveying mechanism 55 is installed on the second lifting cylinder 54.

[0064] See Figures 11-17 A welding clamping fixture for air conditioning accessories includes a support assembly 61 and a pull rod mechanism 63, an air supply assembly 64, a positioning mechanism 65, an air intake assembly 66, and a support rod assembly 67 fixed on the support assembly 61. A workpiece 7 is clamped on the pull rod mechanism 63 and the air supply assembly 64. The support assembly 61 provides mounting positions for the pull rod mechanism 63, the air supply assembly 64, the positioning mechanism 65, the air intake assembly 66, and the support rod assembly 67. A movable handle 62 is also mounted on the support assembly 61 for lifting the support assembly 61. The position of the movable support assembly 61 and the tie rod mechanism 63 restrict the position of the welding part of the workpiece 7 to prevent movement during welding and provide partial fixation. The gas supply assembly 64 is used to introduce protective gas. The protective gas introduced by the gas supply assembly 64 is received by the air inlet assembly 66. The outlet of the gas supply assembly 64 and the inlet of the air inlet assembly 66 are connected by a hose. The protective gas enters the air inlet assembly 66 and then enters the workpiece 7. The strut assembly 67 supports the lower part of the workpiece 7 to prevent displacement during the input of protective gas. The workpiece 7 is an air conditioning accessory.

[0065] The support assembly 61 includes a base plate body 611, on which a first mounting groove 612 and a second mounting groove 613 are provided. A strut assembly 67 is fixed on the second mounting groove 613, and an air intake assembly 66 is installed on the first mounting groove 612.

[0066] The base plate body 611 serves as the supporting body, providing mounting positions for components. The workpiece 7 is positioned by the spacing between the components on the base plate body 611. The first mounting groove 612 provides a mounting position for the air intake assembly 66. The groove height is set according to the bottom height of the workpiece 7, and it cooperates with the air intake assembly 66 to form a snap-fit ​​with the workpiece 7. The second mounting groove 613 provides a mounting position for the support rod assembly 67. The position of the support rod assembly 67 is set according to the bottom length of the workpiece 7 to provide support for the bottom of the workpiece 7 and prevent the workpiece 7 from shifting during the introduction of protective gas.

[0067] The lever mechanism 63 includes a second fixed platform 634, on which a positioning block 631 and a sliding hole 637 are respectively provided. The positioning block 631 is provided with a limiting groove 638, and the second fixed platform 634 is provided with a sliding limiting component 632, which blocks the limiting groove 638.

[0068] The second fixed platform 634 is used for support and positioning. The positioning block 631 provides a positioning length for limiting the workpiece 7. The position of the workpiece 7 is restricted by the limiting groove 638. The sliding hole 637 provides a sliding position for the limiting component 632. The limiting component 632 slides in the sliding hole 637. When the limiting component 632 is in contact with the positioning block 631, it closes the position of the limiting groove 638. When the limiting component 632 is away from the positioning block 631, the workpiece 7 can be taken out in the limiting groove 638.

[0069] The second fixed platform 634 is provided with a positioning fixed surface 635 and a limiting fixed surface 636. The positioning block 631 is fixed on the positioning fixed surface 635, and the sliding hole 637 is fixed on the limiting fixed surface 636.

[0070] The height of the positioning fixing surface 635 and the limiting fixing surface 636 on the second fixing platform 634 is set so that the position of the sliding hole 637 can be adapted to the positioning block 631, and the limiting component 632 can be aligned with the position of the limiting groove 638 when sliding in the sliding hole 637.

[0071] The sliding table 633 is provided with a sliding hole 637. The limiting component 632 includes a second sliding rod 6322, which is disposed in the sliding hole 637. A handle 6321 is installed at one end of the sliding hole 637. A limiting block 6324 is installed at the end of the sliding hole 637 near the positioning block 631, and a buffer spring 6323 is fitted on the sliding hole 637.

[0072] The second slide rod 6322 slides in the sliding hole 637. The limiting block 6324 is larger than the diameter of the buffer spring 6323. The handle 6321 facilitates pulling the second slide rod 6322. When the second slide rod 6322 is pulled outward by the handle 6321, the buffer spring 6323 is compressed by the limiting block 6324. When it is released, the buffer spring 6323 regains its elasticity and springs the limiting block 6324 onto the positioning block 631, which closes the limiting groove 638 and thus restricts the position of the workpiece 7.

[0073] The positioning mechanism 65 includes a support rod 652, a clamping block 653 is mounted on the support rod 652, a support groove 658 is provided on the clamping block 653, a second fixing plate 654 is provided on the side wall of the clamping block 653, and a limit nut 655 is threaded on the second fixing plate 654.

[0074] The support rod 652 is used to fix and provide the installation position. The clamping block 653 fixes the installation position according to the height of the workpiece 7. The clamping block 653 fixes the upper end of the workpiece 7. The second fixing plate 654 provides a limiting position for the limiting nut 655. The limiting nut 655 extends out of the second fixing plate 654 to limit the position of the workpiece 7 in the support groove 658. The limiting nut 655 rotates to extend or retract in the second fixing plate 654 to limit the position of the workpiece 7 above.

[0075] A fixing seat 651 is inserted below the support rod 652. The fixing seat 651 is fixed on the support assembly 61. A support fixing groove 656 is provided on the clamping block 653. The support rod 652 is inserted into the support fixing groove 656. A positioning groove 657 is provided on the side wall of the clamping block 653.

[0076] The support rod 652 is inserted into the fixed seat 651. The fixed seat 651 has a larger contact area with the base plate body 611, making the support rod 652 more stable and avoiding shaking caused by height. The clamping block 653 is fixed on the support rod 652 through the support fixing groove 656, and the installation position of the clamping block 653 is positioned through the positioning groove 657.

[0077] The second fixing plate 654 is fixed on the positioning groove 657. Nuts 659 are provided on both sides of the second fixing plate 654. The threaded part of the limiting nut 655 passes through the two nuts 659.

[0078] The position of the limiting nut 655 is precisely adjusted by two nuts 659, which facilitates better limiting of the workpiece 7 in the support groove 658. The nuts 659 on both sides are set to cooperate with the limiting nut 655.

[0079] The gas delivery assembly 64 includes a gas delivery positioning block 641, which is fixed on the support assembly 61. The gas delivery positioning block 641 is provided with a mounting groove 644. One end of the gas delivery fixing head 642 is provided with a thread. The threaded part passes through the mounting groove 644 and is fixed to the gas delivery nut 645. An air outlet head 643 is installed at the end of the gas delivery fixing head 642 near the gas delivery nut 645.

[0080] The gas supply positioning block 641 is fixed on the base plate body 611 to provide the position for gas supply. The mounting groove 644 facilitates the passage of the gas supply fixing head 642. The threaded setting facilitates the adjustment of the position of the gas supply fixing head 642 and the fixing of the gas supply fixing head 642. The gas supply fixing head 642 is provided with a through hole to facilitate the input of protective gas. The protective gas is output through the gas outlet 643 and then enters and exits into the hose.

[0081] The strut assembly 67 includes a support block 671 with a support groove 672. The air intake assembly 66 includes an air intake positioning block 661 with an air intake positioning groove 662. An air intake head 663 is installed on one side of the air intake positioning block 661.

[0082] The strut assembly 67 is used to support the workpiece 7. The height of the support block 671 matches the bottom height of the workpiece 7. The bottom of the workpiece 7 is limited by the support groove 672 to prevent the bottom of the workpiece 7 from shaking during the gas supply and limiting process. The air inlet positioning block 661 is aligned with the bottom position of the workpiece 7 and is engaged with the bottom position of the workpiece 7 by the air inlet positioning groove 662. The protective gas in the hose is input through the air inlet head 663. When welding the workpiece 7, the protective gas is output to the workpiece 7 through the air inlet head 663 to form a protection and prevent oxidation.

[0083] The workpiece 7 includes a fixed tube 71 and a welded tube 72. An air intake support head is provided below the fixed tube 71, and the welded tube 72 is inserted into the upper part of the air intake support head. A support rod is provided on the side of the air intake support head.

[0084] See Figure 1 and Figure 2 The part connecting the fixed tube 71 and the welding tube 72 needs to be welded. The fixed tube 71 is positioned by the limiting groove 638 to avoid displacement. The air intake support head 73 is fixed in the air intake positioning groove 662 to position the bottom of the air intake support head 73. Then, the fixed tube 71 is positioned by the support groove 658 to avoid weight displacement caused by excessive height. This completes the positioning of the workpiece 7. During the welding process, protective gas is introduced into the air intake support head 73 through the air intake head 663 to prevent oxidation of the welded part between the fixed tube 71 and the welding tube 72.

[0085] By setting a limiting groove 638 on the positioning block 631, the sliding limiting component 632 in the second fixed platform 634 is used for sealing and limiting. A clamping block 653 is installed on the support rod 652, and a support groove 658 is set on the clamping block 653. The limiting nut 655 rotates to limit the support groove 658, which achieves the effect of adjusting and limiting the air conditioning parts, making them easy to remove and preventing displacement during the welding process.

[0086] The support member 51 is a support structure. The chain drive belt 52 is fixed on the support member 51 to form a frame and a conveyor chain. An electric drive chain is provided on the chain drive belt 52 to drive the clamping fixture 6 to move. The conveyor chain on the chain drive belt 52 drives the clamping fixture 6 to move along the direction of the chain drive belt 52. The position of the fixed base plate 53 corresponds to the inspection component 3 and is used to receive the clamping fixture 6 transmitted from the inspection component 3. After the clamping fixture 6 enters the conveying component 5, the drive chain on the chain drive belt 52 clamps the clamping fixture 6 and continues to convey it forward. It can also convey the clamping fixture 6 conveyed from the loading component 4 to the inspection component 3 to complete the handover and ensure the continuity of the conveying.

[0087] See Figure 5 and Figure 6 The welding positioning assembly 2 includes a heating mechanism 26, which includes a slide 261. A drive motor 264 is fixed at one end of the slide 261. The output end of the drive motor 264 is inserted into the slide 261 and connected to a threaded rod 262. A slider 263 is adapted to be provided on the threaded rod 262. A connecting rod 265 is fixed below the slider 263. A heating wire 266 is fixed on the connecting rod 265. A clamping mechanism 27 is installed on the slider 263.

[0088] The slide 261 provides support for the overall structure. The drive motor 264 drives the threaded rod 262 to rotate within the slide 261. The slider 263 cooperates with the threaded rod 262 for transmission. When the drive motor 264 drives the threaded rod 262 to rotate, the slider 263 moves on the threaded rod 262, thereby driving the connecting rod 265 to move axially, realizing the reciprocating action of the actuator. The stroke of the connecting rod 265 is determined by the pitch and rotation angle of the threaded rod 262 to ensure the displacement distance. According to the welding position detected by the camera 34, the position of the connecting rod 265 is adjusted so that it accurately reaches the welding position. The heating wire 266 welds the welding position by electric heating. The connecting rod 265 drives the heating wire 266 to move to the welding point. The heating wire 266 accurately abuts the weld position under the push of the connecting rod 265. After the welding is completed, the connecting rod 265 returns to the initial position to prepare for the next welding.

[0089] See Figure 7 The clamping mechanism 27 includes a slide block 271, which is fixed on the slider 263. A first slide rod 272 is slidably arranged on the slide block 271. A clamping seat 273 is installed on the first slide rod 272. A gripper 275 is installed below the clamping seat 273. A gripper 275 is installed on the clamping cylinder 274. A gripper 275 is provided with a clamping groove 276.

[0090] The slide block 271 is fixed on the slider 263. The first slide rod 272 slides on the slide block 271 to adjust the upper and lower clamping positions. The slide block 271 is used to fix the position of the drive motor 264. The clamping cylinder 274 provides driving force to the gripper 275. The gripper 275 realizes the clamping action under the push of the clamping cylinder 274. The gripper 275 controls the opening and closing of the clamping cylinder 274 through pneumatics, thereby clamping or releasing the workpiece to ensure that the workpiece position is fixed during the processing. The size of the clamping groove 276 matches the size of the workpiece. After the clamping fixture 6 moves to the welding position, the gripper 275 closes quickly under the drive of the clamping cylinder 274, firmly clamping the workpiece in the welding area to ensure that it does not shift during the welding process.

[0091] See Figure 8 The lifting mechanism 45 includes a first lifting cylinder 451, which is fixed inside the loading protective shell 41. The position of the first lifting cylinder 451 corresponds to the position of the lifting limit block 44. A lifting connecting block 452 is installed at the output end of the first lifting cylinder 451. Rotating teeth 453 are provided at both ends of the lifting connecting block 452. A transmission chain 454 is adapted to be installed on the rotating teeth 453. One end of the transmission chain 454 is fixed to the bottom of the loading protective shell 41, and the other end is fixed to the first conveying base plate 461. When the output end of the first lifting cylinder 451 is lifted, it drives the transmission chain 454 to rotate on the rotating teeth 453, and synchronously drives the first conveying mechanism 46 to lift.

[0092] The first conveying mechanism 46 includes a first conveying base plate 461. Multiple first transmission wheels 466 are rotatably arranged on the outer side of the first conveying base plate 461. A first transmission belt 467 is sleeved on the first transmission wheels 466 on both sides. A first transmission motor 462 is installed in the middle of the first conveying base plate 461. A first driving tooth 463 is installed at the output end of the first transmission motor 462. A first transmission shaft 465 is connected between the two first transmission wheels 466. A first driven tooth 464 is installed on the first transmission shaft 465.

[0093] The first conveying base plate 461 provides an installation position. The output end of the first drive motor 462 rotates to provide power. The rotation of the output end of the first drive motor 462 drives the first driving tooth 463 to rotate. The first driving tooth 463 and the first driven tooth 464 are driven by a chain. The first driving tooth 463 drives the first driven tooth 464 to rotate synchronously. The first driven tooth 464 drives the first drive shaft 465 to rotate. The first drive shaft 465 drives the first drive wheels 466 on both sides to rotate. The first drive wheels 466 on both sides are linked by the first drive belt 467, so that the workpiece on the first drive belt 467 is smoothly conveyed to the designated position. The first drive belt 467 remains taut during the transmission process.

[0094] See Figure 9The second conveying mechanism 55 includes a second conveying base plate 551. Multiple second transmission wheels 556 are rotatably arranged on the outer side of the second conveying base plate 551. Second transmission belts 557 are sleeved on the two second transmission wheels 556. A second transmission motor 552 is installed in the middle of the second conveying base plate 551. A second driving tooth 553 is installed at the output end of the second transmission motor 552. A second transmission shaft 555 is connected between the two second transmission wheels 556. A second driven tooth 554 is installed on the second transmission shaft 555.

[0095] The second conveying base plate 551 provides the mounting position. The output end of the second drive motor 552 rotates to provide power. The rotation of the output end of the second drive motor 552 drives the second driving tooth 553 to rotate. The second driving tooth 553 and the second driven tooth 554 are driven by a chain. The second driving tooth 553 drives the second driven tooth 554 to rotate synchronously. The second driven tooth 554 drives the second drive shaft 555 to rotate. The second drive shaft 555 drives the second drive wheels 556 on both sides to rotate. The second drive wheels 556 on both sides are linked by the second drive belt 557, so that the workpiece on the second drive belt 557 is smoothly transported to the designated position. The second drive belt 557 is kept taut during the transmission process.

[0096] The clamping fixture 6 is placed on the first transmission belt 467 and lifted by the output end of the first lifting cylinder 451, driving the first conveying mechanism 46 to move upward until the position of the first conveying mechanism 46 is parallel to the output position of the conveying assembly 5. The first transmission belt 467 conveys the clamping fixture 6 onto the conveying assembly 5, and the chain transmission belt 52 drives the clamping fixture 6 to the position of the fixed base plate 53. The fixed base plate 53 extends upward, driving the second conveying mechanism 55 to move parallel to the input position of the inspection assembly 3. The second transmission belt 557 moves the clamping fixture 6 onto the rolling shaft of the inspection conveyor belt 32, driving the clamping fixture 6 to the welding position. When the clamping fixture 6 moves to the welding position, the heating wire 266 is released from the welding... The position of the connecting pipe 72 moves downward to the connection position between the welding pipe 72 and the fixed pipe 71. At the same time, the first sliding rod 272 moves downward, the clamping cylinder 274 drives the jaws 275 to open, clamping the top of the welding pipe 72. The air intake mechanism 29 inputs nitrogen into the air supply assembly 64 to protect the welding position and prevent oxidation. The heating wire 266 starts heating for welding. After welding is completed, the heating wire 266 stops heating and returns to its original position. The jaws 275 open under pneumatic control to release the welded workpiece. The first sliding rod 272 then moves upward to its original position. The cooling mechanism 28 blows air to cool the welding position, accelerating the solidification of the weld and improving the strength and forming quality of the welded joint, thus achieving the effect of automating the welding of air conditioning parts.

[0097] The output of the drive motor 264 rotates, causing the threaded rod 262 to rotate. The slider 263 moves along the slide groove 261 under the drive of the threaded rod 262, positioning the clamping fixture 6 so that the heating wire 266 can be accurately moved to the welding area. At the same time, the clamping mechanism 27 is moved to the top of the clamping fixture 6 for welding clamping, achieving the effect of positioning and welding the clamping fixture 6.

[0098] A method of using an automatic welding equipment, comprising the above-described automatic welding equipment for air conditioning parts, including:

[0099] Step S1: Install the workpiece 7 on the clamping fixture 6. Place the clamping fixture 6 on the feeding assembly 4. The feeding assembly 4 moves the clamping fixture 6 to the same height as the conveying assembly 5. The feeding assembly 4 moves the clamping fixture 6 to the conveying assembly 5. The conveying assembly 5 conveys the clamping fixture 6 to the inspection assembly 3.

[0100] Step S2: The inspection component 3 performs visual inspection on the workpiece 7 on the clamping fixture 6 to confirm the welding position. If the inspection result meets the preset standard, a signal is sent to the control system to start the welding positioning component 2 to perform precise welding operations. If there is a deviation in the inspection, an alarm device will prompt manual intervention or automatically remove the workpiece.

[0101] Step S3: After receiving the signal, the welding positioning component 2 moves the heating mechanism 26 above the workpiece 7, and the drive motor 264 drives the slider 263 to move to the position where the fixed tube 71 and the welding tube 72 are inserted. The welding positioning component 2 then lowers the heating mechanism 26 to the insertion position, and at the same time, the clamping mechanism 27 moves down to the position of the welding tube 72 to clamp the welding tube 72. At the same time, the air inlet mechanism 29 abuts against the clamping fixture 6.

[0102] Step S4: The air intake mechanism 29 introduces protective gas into the welding pipe 72. At the same time, the heating mechanism 26 heats the welding area evenly, so that the welding materials melt and bond together, and form a strong weld after cooling.

[0103] Step S5: After welding is completed, the clamping mechanism 27 resets, the heating mechanism 26 rises, the air supply mechanism 29 stops supplying air, and the cooling mechanism 28 forces the weld to cool the weld, ensuring rapid solidification of the welded area and reducing thermal deformation.

[0104] Step S6: After cooling, the inspection component 3 performs a second visual inspection on the workpiece 7 on the clamping fixture 6 to confirm whether the weld quality meets the process requirements. If the inspection is qualified, the conveying component 5 will transport the clamping fixture 6 to the conveying component 5 for unloading. If the inspection is unqualified, the defect location will be marked and an alarm will be triggered.

[0105] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
