Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a rotary dual-station cross-flow ultrasonic welding device for fan blades. Background Technology

[0002] A cross-flow fan is a type of sealed fan widely used in industrial and commercial environments. Its working principle is to generate airflow inside the fan through the internal fan blade design, and then draw the air out. The design of the cross-flow fan allows the air to flow continuously in the fan, thereby improving the efficiency and performance of the fan. However, the manufacturing of cross-flow fan blades requires the use of ultrasonic welding equipment.

This is not only laborious but also often affects the pace due to placement deviations, directly reducing processing efficiency. Furthermore, displacement is prone to occur during welding, affecting forming accuracy. In addition, the welding equipment is not equipped with adequate protective devices, and the sparks that fly during welding cannot be effectively controlled, posing a safety hazard to the working environment.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown, a rotary dual-station cross-flow ultrasonic welding device for fan blades includes a worktable 1. A rotary feeding assembly 3 is fixedly connected to the upper surface of the central part of the worktable 1. Clamping assemblies 4 are fixedly connected to the front and rear parts of the upper surface of the rotary feeding assembly 3. A U-shaped frame 2 is fixedly connected to the upper surface of the rear part of the worktable 1, and the U-shaped frame 2 is located outside the clamping assembly 4 in the rear part. A transparent cover 6 is fixedly connected to the rear of the U-shaped frame 2. The lower surface of the transparent cover 6 is fixedly connected to the upper surface of the worktable 1. An ultrasonic welding assembly 5 is fixedly connected to the inner wall of the U-shaped frame 2.

[0026] First, the cross-flow fan blade is placed inside the front clamping assembly 4. Then, under the action of the clamping assembly 4, the cross-flow fan blade can be clamped and fixed. Next, through the action of the rotating feeding assembly 3, the clamping assembly 4 can drive the cross-flow fan blade to rotate and move into the inner wall of the U-shaped frame 2. At this time, another cross-flow fan blade can be clamped and fixed inside the rotating clamping assembly 4. The cross-flow fan blade located inside the U-shaped frame 2 can be welded under the action of the ultrasonic welding assembly 5. The transparent cover 6 allows the workers to easily observe the welding process while also providing protection, thus improving the safety of the working environment.

[0027] like Figure 2 As shown, a partition 35 is fixedly connected to the upper surface of the rotating seat 34 and the partition 35 is located between two mounting plates 41. The outer wall of the partition 35 is movably sleeved with the inner wall of the U-shaped frame 2.

[0028] The partition 35 acts as a barrier between the two ultrasonic welders 55 when welding the cross-flow fan blades, thus ensuring the safety of the workers who place the workpiece in front. At the same time, the transparent cover 6 allows workers to easily observe the welding process while also providing protection, thereby improving the safety of the working environment.

[0029] like Figure 3 As shown, guide rails 56 are slidably connected to the front and rear sides of the two slide blocks 53, and the upper surfaces of the four guide rails 56 are fixedly connected to the top of the inner wall of the U-shaped frame 2 respectively.

[0030] The guide rail 56 enables the electric push rod 52 to stably drive the robotic arm 54 and the ultrasonic welder 55 to move, thus providing support and guidance.

[0031] like Figure 4 As shown, the clamping assembly 4 includes a mounting plate 41. The lower surface of the mounting plate 41 is fixedly connected to the upper surface of the rotating seat 34. Electric push rods 42 are fixedly connected to the inner cavities of the left and right portions of the mounting plate 41. Slider 43 is fixedly connected to the output ends of the two electric push rods 42. The outer walls of the two sliders 43 are slidably connected to the inner walls of the left and right portions of the mounting plate 41, respectively. Two U-shaped push rods 44 are fixedly connected to the opposite sides of the upper portions of the two sliders 43, and the four U-shaped push rods 44 are respectively located above the left and right portions of the mounting plate 41. Two clamping plates 45 are fixedly connected to the opposite faces of the upper portions of the four U-shaped push rods 44, and the two clamping plates 45 are respectively located above the mounting plate 41.

[0032] The two electric push rods 42 enable the two sliders 43 to move towards each other under the action of the U-shaped push rod 44, thereby clamping and fixing the cross-flow fan blades on the upper surface of the support plate 46, thus ensuring the stability during feeding and welding.

[0033] A support plate 46 is fixedly connected to the upper surface of the middle part of the mounting plate 41. The outer walls of the left and right parts of the support plate 46 are respectively movably sleeved with the inner walls of the four U-shaped push rods 44. The upper surface of the support plate 46 overlaps with the lower surfaces of the two clamping plates 45.

[0034] The support plate 46 acts as a barrier to protect the lower drive structure, thereby improving its service life.

[0035] like Figure 5 As shown, the rotary feeding assembly 3 includes an electric push rod 31. The right side of the electric push rod 31 is fixedly connected to the inner cavity of the worktable 1. A toothed plate 32 is fixedly connected to the output end of the electric push rod 31. The outer wall of the toothed plate 32 is slidably connected to the inner cavity of the worktable 1. A gear 33 meshes with the front of the toothed plate 32. The outer wall of the gear 33 is rotatably connected to the inner cavity of the worktable 1. A rotating seat 34 is fixedly connected to the upper surface of the gear 33. The outer wall of the lower part of the rotating seat 34 is rotatably connected to the inner cavity of the worktable 1. The ultrasonic welding assembly 5 includes a fixed frame 51. The upper surface of the fixed frame 51 is fixedly connected to the top of the inner wall of the U-shaped frame 2. Electric push rods 52 are fixedly connected to the inner walls of the left and right parts of the fixed frame 51. Slides 53 are fixedly connected to the output ends of the two electric push rods 52. Robotic arms 54 are fixedly connected to the lower surfaces of the two slides 53. Ultrasonic welders 55 are fixedly installed on the inner walls of the opposite parts of the two robotic arms 54.

[0036] The electric push rod 31 causes the toothed plate 32 to drive the gear 33 and the rotating seat 34 to rotate, thereby causing the two mounting plates 41 to rotate. Driven by the mounting plates 41, the cross-flow fan blades can move to the bottom of the two ultrasonic welders 55. Then, the electric push rod 52 causes the slide 53 to push the robotic arm 54 and the ultrasonic welder 55 closer to the cross-flow fan blades. Then, under the action of the robotic arm 54, the ultrasonic welder 55 can perform welding processing on the cross-flow fan blades, which facilitates loading and unloading during use and improves welding processing efficiency.

[0037] The working principle of this utility model is as follows: First, the cross-flow fan blade is placed on the upper surface of the front support plate 46. Then, through the action of two electric push rods 42, the two sliders 43 are pushed to move towards each other under the action of the U-shaped push rod 44, thereby clamping and fixing the cross-flow fan blade on the upper surface of the support plate 46. Next, through the action of electric push rod 31, the toothed plate 32 can push the gear 33 and the rotating seat 34 to rotate, thereby allowing the two mounting plates 41 to rotate. Under the drive of the mounting plates 41, the cross-flow fan blade can move to below the two ultrasonic welders 55. Then, through the action of electric push rod 52, the sliding seat 53 can push the robotic arm 54 and the ultrasonic welder 55 closer to the cross-flow fan blade. Then, under the action of the robotic arm 54, the ultrasonic welder 55 can perform welding processing on the cross-flow fan blade. The transparent cover 6 allows the workers to easily observe the welding process while also providing protection, improving the safety of the working environment.
