[0016] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0018] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0019] Combination Figure 1-4As shown, the welding device includes a machine base 1, on which a welding support mechanism and a transfer mechanism are respectively provided. The machine base 1 has a slot 3. The welding support mechanism includes a slide 4 installed in the slot 3. The slide 4 is provided with a liftable welding support seat 5.

The rotating seat 10 is provided with a vertically sliding transfer cylinder 11. The drive shaft of the transfer cylinder 11 is provided with a transfer gripper 12. The back of the rotating seat 10 is provided with an adjusting cylinder 13 for driving the transfer cylinder 11 to slide up and down. The slide 8 is also provided with a rotating mechanism for driving the rotating seat 10 to rotate.

[0020] A cross-flow fan is a special type of fan and an important component of air conditioning systems. It is made of multiple impellers connected by ultrasonic welding. The number of impellers is not limited and can be set according to actual needs. It is generally tower-shaped, and the air it blows is concentrated, forming a relay-style airflow transmission.

[0021] In this embodiment, the machine platform is provided with a loading station and a unloading station facing the transfer mechanism, and the loading station has a medium-sized fan wheel. When processing the cross-flow fan blade, the transfer mechanism first clamps a medium-sized fan wheel and moves it to the welding support. Then, the lifting platform drives the ultrasonic crimping head to move downward and contact the current medium-sized fan wheel. At the same time, the transfer mechanism resets and clamps the next medium-sized fan wheel. After that, the ultrasonic crimping head moves upward one station, and the welding support moves downward one height position. The transfer mechanism then places the next medium-sized fan wheel on the current medium-sized fan wheel, and the ultrasonic crimping head moves downward again and presses the next medium-sized fan wheel. At this time, the welding of two adjacent medium-sized fan wheels is completed.

[0022] When the ultrasonic crimping joint completes the welding of one section of the medium-sized wind turbine, the welding support seat descends one height position to await the next medium-sized wind turbine. After several medium-sized wind turbines have been welded and formed into cross-flow fan blades, the welding support seat returns to its initial position and is then transported to the unloading station by the transfer mechanism.

[0023] In the actual welding process, when the transfer mechanism is used to move the intermediate wind turbine, the slide table is facing the loading station, and the transfer gripper clamps the intermediate wind turbine located at the loading station. Then, the rotating seat drives the transfer gripper to rotate towards the welding support. When the transfer gripper rotates directly above the welding support, the adjusting cylinder drives the transfer gripper to move downward until the intermediate wind turbine is located inside the welding support. Afterward, the rotating seat rotates towards the loading station, preparing for the transfer of the next intermediate wind turbine.

[0024] In this embodiment, if Figure 2 The slide table 8 is slidably mounted on the machine base 1. A movable cylinder 14 is provided on the machine base 1 below the slide table 8, and the drive shaft of the movable cylinder 14 is connected to the slide table 8. After the cross-flow fan blade is processed, the transfer gripper clamps the cross-flow fan blade and rotates it backward. After rotating to the correct position, the movable cylinder drives the sliding sleeve to slide to the unloading station for unloading.

[0025] In the above structure, such as Figure 2-3 The rotating seat 10 has a clearance opening 15, and the drive shaft of the adjusting cylinder 13 is provided with a connecting plate 16. The connecting plate 16 passes through the clearance opening 15 and is connected to the adjusting cylinder 13. The adjusting cylinder mainly adjusts the vertical position of the transfer gripper.

[0026] As a preferred structure, such as Figure 3-4 The rotating mechanism includes a rotating shaft 17 rotatably mounted in a rotating support 9. The rotating shaft 17 has a rotating seat 10 at its top and a rotating gear 18 at its bottom. The rotating support 9 has a bottom opening 19 at its bottom. The slide table 8 has a base 2. The side wall of the base 2 has a sliding groove. A spur rack 20 is slidably mounted in the sliding groove. The spur rack 20 is meshed with the rotating gear 18. The slide table 8 also has a rotating cylinder 21. The drive shaft of the rotating cylinder 21 is connected to the spur rack 20.

[0027] In this structure, when the rotating seat needs to drive the transfer gripper to rotate, the rotating cylinder drives the rack to slide in the groove. During this process, the rack drives the rotating gear to rotate, and the rotating seat rotates synchronously under the linkage of the rotating shaft.

[0028] In this structure, such as Figure 1 The lifting platform includes sliding sleeves 22 installed at the four corners of the fixed frame 6. Sliding rods 23 are inserted into the sliding sleeves 22. The bottom of the sliding rods 23 is provided with a lifting seat 24. The ultrasonic crimping connector 7 is installed on the lifting seat 24. The fixed frame 3 is rotatably provided with a lifting rod 25. The lifting rod 25 is connected to the lifting seat 24. The side wall of the lifting rod 24 has a toothed surface along the height direction. The fixed frame 3 is provided with a worm gear motor 26 for driving the lifting rod 24 to move up and down.

[0029] During the welding process of the wind turbine rotor, the lifting platform drives the ultrasonic crimping joint to move vertically. Specifically, the worm gear motor drives the lifting rod to move vertically, which in turn drives the ultrasonic crimping joint to move vertically. During this process, the sliding rod slides within its corresponding sleeve, and the sliding rod and sleeve ensure greater stability of the ultrasonic crimping joint during vertical movement.

[0030] In addition, a lead screw 27 is rotatably mounted on the slide 4, and a lead screw sleeve (covered in the figure) is fitted on the lead screw 27. The lead screw sleeve is connected to the welded support 5. The slide is also equipped with a drive motor 28 for driving the lead screw to rotate.

[0031] During the welding process, when the welding support needs to move downward to a certain height position, the drive motor drives the lead screw to rotate. During the rotation of the lead screw, the lead screw sleeve moves downward a certain distance along the height position of the lead screw.

[0032] In this structure, such as Figure 3 The welding support 5 is also equipped with a clamping handle 29. When the medium-sized wind turbine is placed on the welding support, the clamping handle clamps the wind turbine. Furthermore, the clamping handle keeps the wind turbine clamped throughout the entire welding process, which improves the stability of the entire welding process.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
