Description

Technical Field

[0001] This utility model relates to the field of wind power equipment manufacturing, and in particular to a fan blade loading and unloading machine. Background Technology

[0002] In the fan blade production process of industries such as wind power and home appliances, the loading and unloading of fan blades has traditionally relied heavily on manual operation. This results in high labor intensity, low production efficiency, and the risk of insufficient positioning accuracy due to human error, affecting subsequent processing quality and posing safety hazards. As the industry's demand for automation and batch production of fan blades increases, existing automated loading and unloading equipment is either incompatible with different fan blade specifications due to poor adaptability, or suffers from limited positioning accuracy and low integration, failing to efficiently meet the full-process operational requirements of fan blades from conveying and handling to precise positioning. Therefore, it is necessary to develop integrated, high-precision fan blade loading and unloading equipment to improve the level and stability of fan blade production capacity.

[0003] To adapt to the workshop-style production scenario of small-batch, multi-specification household table fan blades, a fan blade loading and unloading auxiliary device was designed. During loading and positioning, workers place the fan blades flat on the pallet. The pallet surface has rubber contoured grooves that match the curvature of the fan blade surface, quickly aligning the fan blade mounting holes with the processing baseline to avoid positioning deviations. In the manual fixing stage, a metal pressure rod is pressed down. The rubber pad at the bottom of the pressure rod fits against the edge of the fan blade, applying uniform pressure through leverage to gently fix the fan blade and prevent processing displacement. During the feeding and alignment stage, the pallet is manually pushed along the guide rail to deliver the fixed fan blade to the processing station. Limit blocks on the guide rail prevent overtravel. During unloading and resetting, after processing, the pallet is pulled back to reset, the pressure rod is lifted, and the finished product is removed, completing a single loading and unloading operation. The equipment has a simple structure, is easy to maintain, and is suitable for workshop-style production.

[0004] In workshop-style production scenarios where this fan blade loading and unloading auxiliary equipment is adapted to small batches of multi-specification household table fan blades, the lack of adjustable slide rail components and fan blade positioning and clamping components will result in obvious drawbacks in terms of fixation stability, adaptation flexibility, processing accuracy, and ease of operation. Without adjustable slide rail components, the equipment relies solely on manual pressure rods and rubber pads for fixation, which cannot adapt to fan blades with different curvatures through flexible adsorption. Improper pressure can lead to fan blade deformation, scratches, or vibration displacement during processing. Moreover, workers need to handle the fan blades by hand, which increases hand fatigue and can scratch the coated fan blade surface. When changing to different specifications of fan blades, it is necessary to frequently adjust the pressure rod or replace the rubber pads, resulting in low changeover efficiency. The lack of a fan blade positioning and clamping assembly, relying solely on the groove of the contour plate to align with the baseline, makes it difficult to correct for minute dimensional tolerances of the fan blades. This can lead to defects such as misalignment of the machining baseline, hole offset, and uneven cutting edges. Furthermore, the lack of omnidirectional clamping during machining results in weak vibration resistance of the fan blades, making them prone to loosening and deformation due to external forces. Changing models also requires disassembling and replacing the contour plate or adjusting the fixing points of the pressure rod, which is cumbersome and time-consuming. This reduces the finished product qualification rate and production efficiency, and also contradicts the needs of adapting to small-batch, multi-specification production. Therefore, a fan blade loading and unloading machine is proposed to solve the above problems. Utility Model Content

[0014] This utility model has the following beneficial effects: 1.

The whole system is compatible with different specifications of fan blades, improves positioning accuracy and operation convenience, and effectively improves the pain points of traditional manual loading and unloading.

[0022] Working principle: The adjustable slide rail assembly uses the transverse moving guide rail 7 as the basic sliding reference. During operation, the actuator 11 at the top of the longitudinal moving slide 8 provides power, driving the longitudinal moving slide 8 to slide smoothly along the transverse moving guide rail 7, thereby adjusting the lateral position of the suction cup 19 to meet the adsorption requirements of different specifications of processed fan blades 26. The moving block guide rail 13 fixed on the outer wall of the longitudinal moving slide 8 slides in cooperation with the moving slider 9. The moving slider 9 is also linked with the moving shaft 12, which can drive the moving shaft 12 to adjust its position longitudinally. The limiting block 10 at the top of the moving shaft 12 can prevent it from sliding over-travel and falling off. The bottom of the movable shaft 12 is connected to the return spring 15 via the connector 14. The return spring 15 is connected to the lifting ring 16 below it. The lifting ring 16 is rotatably engaged with the flange connecting plate 17. The operator can adjust the suction force of the suction cup 19 by rotating the movable handle 18 on the flange connecting plate 17 to adapt to different curvatures of the fan blade. During suction, the return spring 15 offsets the impact, avoiding pressure damage to the processed fan blade 26, and realizing flexible and precise handling of the processed fan blade 26.

[0023] When the fan blade positioning and clamping assembly is working, the conveyor frame 21 first provides basic support and conveying. The conveyor frame 21 is firmly placed on the ground by the fixed support legs 23 fixedly connected to the outer wall, preventing shaking during the operation of the assembly. The conveyor belt 22 set on its inner wall can accurately transport the fan blade 26 to be processed to the core positioning structure, the fan blade positioning table 20, replacing manual handling and improving conveying efficiency and accuracy. When the fan blade 26 arrives at the fan blade positioning table 20, the fan blade positioning post 25 at one end of the top of the positioning table will be accurately aligned with the mounting hole of the fan blade 26. At the same time, the fan blade positioning post 25 The top-fixed fan blade support column 24 supports the blade surface of the processed fan blade 26. The two work together to complete the initial precise positioning of the fan blade, ensuring that the fan blade reference is aligned with the processing station. Finally, the operator performs clamping operation through the clamping arm bracket 27 at the other end of the top of the fan blade positioning table 20. By rotating the clamping handle 28 at the top of the clamping arm bracket 27, the clamping linkage 29 connected to it is driven to move in tandem, so that the clamping fixing head 30 at one end of the clamping linkage 29 fits tightly against the outer wall of the processed fan blade 26, achieving stable clamping of the fan blade and providing a stable and precise positioning foundation for subsequent processing.
