Description

Technical Field

[0001] This invention relates to the field of motor rotor assembly technology, specifically to rotor fan blade press-fitting equipment and press-fitting method. Background Technology

[0002] In the field of motor manufacturing, the installation of rotor fan blades is one of the key processes. It typically involves applying adhesive before pressing the blades into specific positions on the rotor. Traditional processes generally rely on manual operation or semi-automated equipment, which has several technical limitations: First, manual adhesive application makes it difficult to ensure uniform adhesive application and consistent application paths, easily leading to adhesive breaks, accumulation, or missed areas, affecting bond strength and sealing. Second, the pressing process relies heavily on experience to control pressure, making precise pressure adjustment and maintenance impossible, resulting in uneven stress distribution on the contact surface between the fan blades and the rotor, easily causing deformation or loosening. Third, the installation position depends on visual inspection or simple tooling, resulting in poor consistency. Especially in mass production, the accumulated error is significant, directly affecting the dynamic balance performance and operational stability of the rotor assembly. For high-performance motors, especially in high-speed, high-precision applications, even slight deviations in the rotor fan blade position can cause increased vibration and noise, decreased efficiency, and even equipment failure.

[0003] Although some automated dispensing equipment has been put into use, its functions are often relatively simple, mostly limited to the dispensing stage, and it has failed to effectively integrate with subsequent processes such as flipping and alignment, press forming, and quality inspection. This segmented operation mode not only increases workpiece turnaround time and positioning errors, but also makes it difficult to systematically coordinate and trace process parameters, failing to meet the comprehensive requirements of modern intelligent motor manufacturing for high consistency, full-process controllability, and efficient production cycle. Summary of the Invention

[0004] To address the limitations of existing dispensing equipment due to its single function, this invention proposes a rotor fan blade pressing device and method. This device integrates multiple processes, including rotor conveying, gripping, circumferential glue application, attitude flipping, fan blade pressing, and installation quality inspection, into a single unit. By employing a glue application method that directly drives the rotor rotation via a synchronous belt, in conjunction with a dispensing machine, continuous, uniform, and seamless glue application is achieved on a specific annular area of ​​the rotor.

[0005] The technical solution adopted by this invention is as follows: A rotor fan blade pressing device includes a frame, on which a first conveyor belt, a first robotic arm, a gluing assembly, a turning assembly, a second robotic arm, a pressing assembly, and a testing assembly are provided.

[0007] Optionally, the pressing assembly includes a material handling assembly and a pressure block. The material handling assembly includes a material handling robot, a support plate, and a support column. The bottom of the support column is slidably connected to the slide rail on the frame via a slider. The support plate is slidably installed on the support column. A spring is sleeved on the outer peripheral wall of the support column. One end of the spring abuts against the top of the slider, and the other end of the spring abuts against the bottom of the support plate.

[0008] Optionally, the bottom of the material handling robot is provided with a magnet for adsorbing the rotor, and the pressure block is provided with the pressure groove.

[0009] Optionally, a pressure sensor is provided between the output end of the downward driving component and the support cross plate, and the pressure sensor is used to detect the downward pressure applied by the downward driving component in real time.

[0010] Optionally, the test assembly includes a test base and a test plate. The test base has a slot that mates with the rotor shaft. The test plate has a top block that is opposite to the test base. The test base is connected to a second cylinder, which drives the test base to move toward the top block. The test plate has a detection element that detects the installation position of the fan blades on the rotor.

[0011] Optionally, the frame is further provided with a second conveyor belt for conveying the fan blades and a third cylinder for pushing the fan blades on the second conveyor belt into the pressure groove. The second conveyor belt is located on one side of the pressure block, and the piston rod of the third cylinder is correspondingly arranged with the pressure groove.

[0012] This invention also discloses a rotor fan blade pressing method using the rotor fan blade pressing equipment described above, comprising the following steps:

[0013] S1. The first conveyor belt transports the rotor to a position below the first robotic arm;

[0014] S2. The first robotic arm picks up the rotor and places it on the timing belt of the glue application assembly;

[0015] S3. The controller starts the rotary motor, which drives the rotor to rotate. At the same time, it controls the dispensing machine to move towards the rotor and dispense glue, thus completing the circumferential glue application.

[0016] S4. After the adhesive is applied, the first robotic arm moves the rotor onto the flipping block of the flipping assembly;

[0017] S5. The controller controls the first cylinder to drive the tilting block to rotate 90°, so that the rotor is in a vertical position, and the second robotic arm picks up the rotor.

[0021] S9. After pressing is completed, the controller controls the pressing drive to reset, which drives the support plate to rise.

[0022] S10, The material handling assembly transfers the rotor back to the second robotic arm;

[0023] S11. The second robotic arm transfers the rotor to the test fixture of the test assembly;

[0024] S12. The controller starts the second cylinder to clamp the rotor between the test seat and the top block for installation quality inspection.

[0025] S13. If the inspection is qualified, the second robot will transfer the rotor to the finished product station; if it is not qualified, the controller will trigger an alarm.

[0026] Optionally, during the pressing process, the controller reads the actual pressure value fed back by the pressure sensor in real time, compares the actual pressure value with a preset pressure threshold, and controls the output of the pressing drive to make the actual pressure value reach and stabilize within the preset pressure threshold range.

[0027] Optionally, the frame is also equipped with a waiting station. Before step S11, if the test component is busy, the second robot first places the rotor in the waiting station, and then executes step S11 after the test component is idle.

[0028] The beneficial effects of this invention are: it integrates multiple processes such as rotor conveying, gripping, circumferential gluing, attitude flipping, fan blade pressing, and installation quality inspection into a single device, achieving fully automated continuous operation from raw rotor blank to finished assembly. This significantly reduces the turnaround time and repetitive positioning errors between different workstations, effectively improving production efficiency and product consistency. By employing a gluing method that directly drives the rotor rotation via a synchronous belt, combined with a dispensing machine, continuous, uniform, and seamless gluing is achieved on a specific annular area of ​​the rotor, overcoming problems such as glue breaks and uneven thickness that may occur with manual or simple rotary gluing, thus ensuring the firm adhesion of the fan blades.

Detailed Implementation

[0033] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 3 As shown, this embodiment discloses a rotor fan blade pressing device and pressing method, including a frame 100. Along the flow direction, the frame 100 is sequentially arranged a first conveyor belt 200, a first robotic arm 300, a gluing assembly 400, a tilting assembly 500, a second robotic arm 600, a pressing assembly 700, and a testing assembly 800. The first conveyor belt 200 is used to transport the rotor to be installed to a working position below the first robotic arm 300. The first conveyor belt 200 can be a belt conveyor, chain conveyor, or roller conveyor, preferably a stepping conveyor to ensure accurate rotor positioning.

[0035] The first robotic arm 300 is a Cartesian coordinate robotic arm, or a multi-joint robotic arm, and is equipped with a pneumatic or electric gripper at its end for gripping the rotor from the first conveyor belt 200 and precisely placing it into the designated position on the adhesive application assembly 400. A mounting block 210 for placing the rotor is fixedly installed on the first conveyor belt 200.

[0036] The adhesive application assembly 400 includes a dispensing machine 410 and a tumbling assembly 420. The tumbling assembly 420 includes a rotary motor 421, a drive pulley 422, a timing belt 423, and a driven pulley 424. The output shaft of the rotary motor 421 is coaxially connected to the drive pulley 422 via a coupling to ensure accurate power transmission. The timing belt 423 is made of polyurethane or rubber, which has good friction performance and dimensional stability. It is wound around the outer peripheral walls of the drive pulley 422 and the driven pulley 424 to form a closed transmission circuit. The surface of the timing belt 423 may be provided with anti-slip textures or a coating to increase the friction between it and the rotor shaft and prevent slippage.

[0037] The dispensing machine 410 is mounted on a slide of a linear motor, which drives the dispensing machine 410 to move. The dispensing machine 410 can use a precision metering pump in conjunction with a dispensing needle to precisely control the amount and position of the dispensing agent.

[0038] Specifically, the first robotic arm 300 places the rotor shaft horizontally on the synchronous belt 423. The controller starts the rotary motor 421, which drives the synchronous belt 423 to rotate via the drive wheel 422. The friction between the synchronous belt 423 and the rotor shaft drives the rotor to rotate at a constant speed around its own axis. Simultaneously, the linear motor 430 drives the dispensing machine 410 to move towards the rotor to a set distance, with the dispensing needle aligned with the annular area on the rotor where the fan blades need to be installed. During the rotor's rotation, the dispensing machine 410 continuously dispenses adhesive, completing the circumferential adhesive application after one revolution of the rotor. Directly driving the rotor rotation via the synchronous belt is a simple and reliable structure. Combined with the linear motor-driven dispensing machine, it achieves synchronization between rotor rotation and dispensing movement, ensuring uniform and continuous adhesive application without seams or overlaps.

[0039] like Figure 2 As shown, a support plate 110 is provided on the frame 100. The passive wheel 424 is rotatably mounted on one side of the support plate 110 through a bearing seat. A deep groove ball bearing or a needle roller bearing is installed in the bearing seat to ensure that the passive wheel 424 rotates flexibly and has small radial runout.

[0040] The tilting assembly 500 includes a tilting block 510 and a first cylinder 520. The tilting block 510 is rotatably mounted on the other side (e.g., the right side) of the support plate 110 via a rotating shaft. Both ends of the rotating shaft are mounted on the support plate 110 via bearing seats.

[0041] The top of the flipping block 510 is machined with an arc-shaped groove that matches the rotor's shape. The radius of curvature of the arc-shaped groove is slightly larger than the outer diameter of the rotor core, which facilitates rotor placement and ensures stable positioning. Rubber or polyurethane pads can be attached to the surface of the arc-shaped groove to prevent damage to the rotor surface.

[0042] The cylinder body of the first cylinder 520 is tilted and fixed to the bottom of the support plate 110 by a bracket, and the piston rod of the first cylinder is connected to the side wall of the flipping block 510 by a hinge. When the piston rod of the first cylinder 520 extends or retracts, it drives the flipping block 510 to rotate around the rotating shaft 511, realizing a flipping of 0-90 degrees.

[0043] like Figure 2As shown, the material handling assembly 700 includes a material handling assembly 710 and a pressure block 720. The material handling assembly 710 includes a material handling robot 711, a support plate 712, and a support column 713. A horizontal slide rail 101 is provided on the frame 100, and the length direction of the slide rail 101 corresponds to the movement path of the second robot 600. The bottom of the support column 713 is slidably connected to the slide rail 101 via a slider 714. The slider 714 is equipped with a linear bearing or ball bushing to ensure smooth sliding and low resistance. The support plate 712 is slidably sleeved on the support column 713 via a linear bearing and can move up and down along the axial direction (vertical direction) of the support column 713. A spring 715 is sleeved on the outer peripheral wall of the support column 713. The bottom of the spring 715 abuts against the top surface of the slider 714, and the top abuts against the bottom surface of the support plate 712. Spring 715 serves as a buffer and assists in resetting. After pressing is completed, it helps the support plate 712 to quickly reset.

[0044] A material handling robot 711 is fixedly installed at the bottom of the supporting horizontal plate 712. The end of the material handling robot 711 is equipped with an electromagnet or permanent magnet block for attracting the rotor shaft end. An electromagnet is preferred, and the magnetic force can be controlled by energizing / disabling it, facilitating rotor placement and removal. A pressure block 720 is fixedly installed on the worktable of the frame 100, located at the end of the slide rail 101. A pressure groove 721 is machined on the top of the pressure block 720. The shape and size of the pressure groove 721 match the fan blade to be installed, used for positioning and supporting the fan blade. The depth of the pressure groove 721 is slightly greater than the thickness of the fan blade to ensure stable placement. The downward pressure drive is a servo electric cylinder or a pneumatic servo cylinder, installed on the top of the support column 713. The piston rod of the downward pressure drive extends downward, and a pressure sensor is installed between its output end and the supporting horizontal plate 712.

[0045] The pressure sensor is preferably a strain gauge pressure sensor or a piezoelectric pressure sensor, and is connected to the analog input port of the controller via a signal line. The pressure sensor detects the downward pressure applied to the support plate 712 by the pressing drive in real time, and converts the pressure signal into an electrical signal and transmits it to the controller. In other embodiments, the pressure sensor can also be integrated into the part of the material handling robot 711 that contacts the rotor, directly detecting the pressing force acting on the rotor.

[0046] On one side of the pressure block 720 of the pressing assembly 700, a second conveyor belt 730 and a third cylinder 740 are also provided on the frame 100. The second conveyor belt 730 can be a belt conveyor, a vibratory feeder, or a stepping conveyor, used to convey the fan blades one by one to the preparatory position between the pressure block 720 and the third cylinder 740. The third cylinder 740 is installed horizontally, and its piston rod has a push block at the front end, which is directly opposite the inlet of the pressure groove 721 of the pressure block 720.

[0047] Before the material handling assembly 710 moves the rotor to the pressing station, the controller first starts the second conveyor belt 730 to transport the fan blade to the ready position. Then, the controller controls the piston rod of the third cylinder 740 to extend, and the pusher smoothly pushes the fan blade into the pressing groove 721, completing the automatic feeding of the fan blade. Afterward, the material handling assembly 710 positions the rotor directly above the pressing groove to perform the pressing operation. This structure achieves automatic feeding and positioning of the fan blade, further improving the automation level and production cycle of the equipment.

[0048] The test assembly 800 includes a test base 810, a test plate 820, and a second cylinder 830. The test base 810 has a slot that precisely matches the rotor shaft; the diameter of the slot is slightly larger than the shaft diameter to facilitate rapid rotor insertion. The bottom of the test base 810 is connected to the piston rod of the second cylinder 830, which is fixed below the frame 100 and drives the test base 810 to move vertically. The test plate 820 is fixed to the frame 100 by a column and is located directly above the test base 810. The bottom of the test plate 820 has a top block 821, the center line of which coincides with the center line of the slot in the test base 810. A test piece 822 is mounted on the test plate 820. The detection component 822 may be any one or more of the following: a vision sensor (such as an industrial camera) whose lens is aimed at the rotor blade and analyzes the installation angle, height, etc. of the blade through image processing; a laser displacement sensor that emits a laser beam to the end face of the blade and measures the axial height of the blade through the reflected light; or a contact probe that contacts the side of the blade under the drive of a cylinder and measures the radial extension of the blade through a displacement sensor.

[0049] This embodiment also provides a rotor fan blade pressing method using any of the above-mentioned devices, wherein a controller (such as a PLC or industrial computer) coordinates and controls each actuator to work according to the following process:

[0050] S1: Material conveying

[0051] The first conveyor belt 200 transports the rotor to be fitted with the fan blades to a predetermined position below the first robotic arm 300 in a step-by-step manner. The first conveyor belt 200 may be equipped with a photoelectric sensor or a position sensor to detect the rotor's arrival signal.

[0052] S2: Rotor transfer

[0053] According to the control command, the first robotic arm 300 moves above the first conveyor belt 200, grips the rotor, and then moves above the synchronous belt 423 of the glue application assembly 400, placing the rotor shaft horizontally on the synchronous belt 423.

[0054] S3: Circumferential coating

[0055] The controller starts the rotary motor 421, setting its speed to 10-50 rpm (adjusted according to rotor diameter and process requirements). Simultaneously, the linear motor 430 drives the dispensing machine 410 to move to a set distance (e.g., 2-5 mm) from the rotor surface. Once the rotor begins to rotate, the metering pump of the dispensing machine 410 starts, dispensing adhesive at a constant flow rate. The controller calculates the rotational speed of the rotary motor 421 and the moving speed of the dispensing machine 410 based on the rotor diameter and the number of fan blade installation positions, synchronizing the two to ensure a continuous and uniform adhesive application path covering the annular area to be bonded.

[0056] S4: Rotor transferred to the tilting station

[0057] After the adhesive is applied, the rotary motor 421 stops, and the dispensing machine 410 resets. The first robotic arm 300 picks up the rotor again and transfers it into the arc-shaped groove 512 of the flipping block 510 of the flipping assembly 500.

[0058] S5: Flipping and Transfer

[0059] The controller controls the piston rod of the first cylinder 520 to extend, driving the tilting block 510 to rotate 90 degrees around the rotating shaft 511, so that the rotor changes from a horizontal state to a vertical state (the rotating shaft is vertical). At this time, the second robot arm 600 has moved into position, and its grippers grasp the upper journal of the rotor.

[0060] S6: The rotor is transferred to the pressing station.

[0061] The second robotic arm 600 moves in a direction perpendicular to the slide rail 101 (i.e., the arrangement direction as described in claim 4) to move the rotor directly below the picking robotic arm 711. The magnet of the picking robotic arm 711 is energized, attracting the lower end journal of the rotor.

[0062] S7: Material handling component positioning

[0063] The second robotic arm 600 releases and removes the rotor. The entire material handling assembly 710 moves along the slide rail 101 under the drive of a horizontal drive device (such as a cylinder or motor) until the rotor is directly above the pressure groove 721 of the pressure block 720. The fan blades have been pre-placed in the pressure groove 721.

[0064] S8: Pressing process

[0065] The controller controls the downward pressure drive to move the support plate 712 downwards. During the pressing process, the controller reads the actual pressure value P fed back by the pressure sensor in real time. actual .

[0066] The controller will P actual With the preset pressure threshold P set Compare and calculate the pressure error e = P set - Pactual .

[0067] The controller uses a PID closed-loop control algorithm to calculate the control quantity u(t) based on the error e:

[0068]

[0069] Where K p K i K d These are the proportional coefficient, integral coefficient, and derivative coefficient, respectively, which are obtained through process testing.

[0070] The controller converts the control quantity u(t) into adjustment commands for the downward-pressing drive component (such as the current of a servo electric cylinder or the pressure of a pneumatic servo cylinder), dynamically adjusting its output force to make P... actual Rapidly approaching and stabilizing at P set Within the allowable error range (e.g., ±5%).

[0071] When P actual Once the pressure stabilizes within the set range, the controller starts timing to maintain the pressing force at the holding time T (e.g., 3-10 seconds, depending on the adhesive properties) to ensure the adhesive is initially cured.

[0072] This closed-loop pressure control algorithm enables precise dynamic adjustment of the pressing force, overcoming force fluctuations caused by factors such as part dimensional tolerances and temperature changes, thus ensuring the consistency of pressing quality for each product. Preset pressure threshold P set Based on the setting of process parameters such as the yield strength of the wind turbine blade material and the ideal curing pressure of the adhesive, a direct link between process requirements and equipment control was achieved.

[0073] S9: Pressing complete

[0074] After the pressure holding time is reached, the controller controls the piston rod of the downward drive component to retract, causing the support plate 712 to rise and reset. The elastic force of the spring 715 assists the support plate 712 to rise quickly and smoothly.

[0075] S10: Rotor return

[0076] The material handling assembly 710 moves in the opposite direction along the slide rail 101, returning to the handover position near the second robot arm 600. The magnet of the material handling robot arm 711 is de-energized, releasing the rotor. The second robot arm 600 moves over to grip the rotor.

[0077] S11: Rotor transferred to the testing station

[0078] The second manipulator 600 transfers the rotor above the test seat 810 of the test component 800. If the test component 800 is busy at this time (for example, the previous rotor is being detected), the second manipulator 600 can first place the rotor on the waiting station 900 set on the rack 100. The waiting station 900 can be designed as a simple V-shaped bracket or a tray with a buffer, which is located near the test component 800 but does not affect its operation. The controller has built-in queue management logic. When the test component 800 is idle, it then commands the second manipulator 600 to retrieve the rotor from the waiting station 900 and place it into the test seat 810. The setting of the waiting station decouples the pressing rhythm and the testing rhythm, allowing the pressing process to continue production when the testing time is long, improving the overall equipment utilization rate and production efficiency.

[0079] S12: Installation Quality Inspection

[0080] The second manipulator 600 vertically places the rotor into the slot hole of the test seat 810 and then moves away. The controller starts the second cylinder 830 to drive the test seat 810 to顶升vertically, so that the upper end journal of the rotor contacts the top block 821, and the rotor is stably clamped between the test seat 810 and the top block 821.

[0081] The controller starts the detector 822 to conduct detection: If the detector is a laser displacement sensor, it measures the height value of the upper end face of the wind blade relative to the reference plane.

[0082] S13: Result Processing and Sorting

[0083] The controller compares the detection result with the preset standard tolerance range:

[0084] If all detection parameters are within the qualified range, it is judged as a qualified product. The controller commands the second manipulator 600 to take out the rotor from the test seat 810 and transfer it to the finished product station (such as the first blanking conveyor belt or the finished product collection box).

[0085] If any parameter exceeds the tolerance, it is judged as a non-conforming product. The controller triggers an audible and visual alarm, and can transfer the rotor to the non-conforming product collection area through the second manipulator 600, or record the product number for subsequent processing.

[0086] This fully automatic detection method replaces manual visual inspection or sampling inspection, realizes 100% online full inspection, promptly discovers installation defects, and ensures the quality consistency of the products leaving the factory.

Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
