Description

Technical Field

[0001] This invention relates to the field of impeller testing, and in particular to a fully automatic impeller dynamic balancing test and weight removal device. Background Technology

[0002] An impeller is a wheel disk equipped with moving blades, or the general term for a wheel disk and the rotating blades mounted on it.

[0003] The impeller is the core component of a robotic vacuum cleaner, driven by a high-speed rotating motor. The robotic vacuum cleaner operates by generating negative pressure through the impeller, so each one must undergo dynamic balancing testing. Otherwise, dynamic imbalance during high-speed rotation will generate significant vibrations, and the noise generated by these vibrations will directly affect the quality and performance of the product, reducing the customer's experience.

[0004] Currently, Chinese utility model patent CN209166711U discloses a centrifugal impeller dynamic balancing testing mechanism, including a base with two bearing seats at its upper end, bearings installed in the bearing seats; a main shaft, rotatably mounted in the inner hole of the bearings in a horizontal direction, with a baffle at the front end of the main shaft having an outer diameter larger than the inner diameter of the mounting hole of the centrifugal impeller, and a mounting shaft at the front end of the baffle, the outer diameter of the mounting shaft matching the inner diameter of the mounting hole, and the mounting shaft being coaxial with the main shaft; a centrifugal impeller inserted into the mounting shaft through the mounting hole, the head end of the mounting shaft having an external thread, a nut screwed onto the external thread, the nut pressing and fixing the centrifugal impeller to the baffle; a main shaft drive mechanism, disposed in the base, which drives the main shaft to rotate; a dial indicator, mounted on the base, with the dial indicator needle in contact with the surface of the main shaft; and a main shaft locking device, mounted on the base, used to lock and fix the main shaft.

[0005] While existing impeller dynamic balancing testing mechanisms can detect the dynamic balance of impellers, in actual use, after the impeller dynamic balancing test, it is necessary to remove or add weight to correct the dynamic balance of the impeller. Removing or adding weight requires removing the impeller and then processing it. The processed impeller needs to be placed on the testing mechanism again for testing. The whole process is cumbersome and inefficient. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automatic impeller dynamic balancing test and weight removal device, which has the advantages of automatic testing and weight removal and high production efficiency.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a fully automatic impeller dynamic balancing test and weight reduction device, comprising a test mechanism and a dynamic balancing correction mechanism disposed around the test mechanism. The test mechanism includes a power shaft for fixing the impeller and driving the impeller to rotate, a power source connected to the power shaft, a swing frame sleeved on the outside of the power shaft, and an acceleration sensor mounted on the swing frame. The power shaft is connected to an angle recognition component, which is connected to the acceleration sensor to identify the unbalance angle of the impeller and rotate the unbalance angle of the impeller to the dynamic balancing correction mechanism. The dynamic balancing test mechanism includes a conveyor seat that drives the dynamic balancing test mechanism closer to or away from the power shaft.

[0008] Through the above technical solution, the testing mechanism drives the impeller to rotate, and then calculates the impeller's imbalance based on the data from the acceleration sensor; the angle recognition component is connected to the acceleration sensor, and rotates the impeller's imbalance angle to the dynamic balancing correction mechanism based on the impeller's imbalance; the dynamic balancing correction mechanism removes or adds weight to the impeller's imbalance angle near the power shaft. Both testing and correction are automated, and multiple corrections can be performed to achieve impeller balance. The testing mechanism does not need to remove the impeller for correction, thus improving the equipment's efficiency and the impeller's quality.

[0009] The present invention is further configured such that: the angle recognition component includes an origin position sensor installed at the power source and an angle recognition sensor installed on the outside of the power shaft; a fixing sleeve is sleeved on the outside of the power shaft; and an angle display plate is installed on the fixing sleeve.

[0010] Through the above technical solution, the angle recognition sensor determines the initial angle of the impeller to identify the unbalanced angle of the impeller; the origin position sensor controls the power source to automatically rotate to the unbalanced position according to the determined unbalanced angle, so that the dynamic balancing correction mechanism can correct it and improve the accuracy of the equipment; the angle display board is installed on the power shaft for easy observation of the angle.

[0011] The present invention is further configured such that: the testing mechanism and the dynamic balance correction mechanism are connected to a base, and a vibration isolation block is provided between the swing frame and the base; the vibration isolation block is a damping vibration isolation block, and the vibration isolation block includes a mounting hinge column installed on the base and a shock-absorbing rubber seat provided between the mounting hinge column and the swing frame.

[0012] Through the above technical solution, the high-speed rotation of the power source will generate vibration, which in turn will drive the power shaft and impeller to vibrate. The vibration isolation block reduces the vibration during the test and improves the accuracy of the equipment.

[0013] The present invention is further configured such that: the dynamic balancing correction mechanism includes a weight-removing seat disposed on one side of the power shaft, weight-removing shears mounted on the weight-removing seat, and a conveying seat that drives the weight-removing seat to move closer to or away from the impeller; a waste material discharge box is disposed between the weight-removing seat and the power shaft; the conveying seat includes a ball screw that drives the weight-removing seat to slide, a coupling connected to the ball screw, and a drive source connected to the coupling to drive the ball screw to rotate.

[0014] Through the above technical solution, the drive source moves according to the imbalance and is precisely displaced by the ball screw to ensure the walking accuracy of the de-weighting shears; the de-weighting shears automatically trim, and the mechanical control precision is higher; the waste material box is used to receive the waste generated during de-weighting.

[0015] The present invention is further configured to include a feeding mechanism, the feeding mechanism including a rotating disk rotatably disposed above the base, a positioning rod detachably disposed on the rotating disk, and a positioning seat installed below the rotating disk to pick up the impeller. A slide rail is provided below the positioning seat to drive the positioning seat closer to or away from the rotating disk, and a feeding sensor and a discharging sensor are respectively installed at both ends of the slide rail.

[0016] Through the above technical solution, multiple impellers are inserted on the positioning rods, which are detachably mounted on the rotating disk, making it easy to replace the positioning rods and thus easy to install the impellers on the feeding mechanism; the feeding sensor detects whether the positioning seat is receiving material, and the discharging sensor detects whether the material picking mechanism is picking up material. The feeding sensor, discharging sensor and slide rail work together to make the feeding of the impellers form a cycle.

[0017] The invention is further configured such that: a connecting pin is inserted at one end of the positioning rod, and a positioning plate abutting against the rotating disk is provided at the other end; a gravity block is sleeved on the outside of the positioning rod; the gravity block and the positioning rod are slidably connected to the pressure impeller to the positioning seat; and a handle is installed on the positioning plate.

[0018] The above technical solution uses a connecting pin and a gravity block to set the two ends of a series of impellers, fixing the impellers to the positioning rod. At the same time, the positioning rod is installed on the rotating disk. When the connecting pin is removed, the gravity block presses down on the impellers, so that the impellers are passed in sequence. The positioning disk abuts against the rotating disk to position the top of the positioning rod and prevent the positioning rod from shaking. The handle facilitates the removal and replacement of the positioning rod.

[0019] The present invention is further configured such that: the rotating disk is fixedly connected to a drive shaft, and an indexing sleeve is snapped onto one end of the drive shaft away from the rotating disk; the indexing sleeve is connected to a drive assembly; the drive assembly includes a clutch cylinder that drives the indexing sleeve to engage or disengage from the drive shaft and an indexing cylinder that drives the drive shaft to rotate; a gear is sleeved on the outer side of the drive shaft; and a rack that meshes with the gear is provided on the indexing cylinder.

[0020] Through the above technical solution, the clutch cylinder controls the engagement and disengagement of the drive shaft and the indexing sleeve. When engaged, it facilitates the indexing cylinder to drive the rotating disk to rotate, and when disengaged, it facilitates the reset of the indexing cylinder. The indexing cylinder and the drive shaft are connected by a gear and rack, which ensures the accuracy of the impeller conveying and increases the precision of the equipment.

[0021] The present invention is further configured to include an impeller fixing mechanism for fixing the impeller to the testing mechanism, wherein a lower fixing seat is fixed on the power shaft; the impeller fixing mechanism includes an upper fixing seat that is threadedly connected to the lower fixing seat to fix the impeller, a servo motor that drives the upper fixing seat to rotate, and a lifting cylinder that drives the upper fixing seat to move closer to or away from the lower fixing seat; the testing mechanism is connected to a vacuum generator, and the lower fixing seat is adsorbed onto one end of the main shaft of the servo motor.

[0022] With the above technical solution, the lower fixed seat is installed on the power shaft and abuts against one side of the fixed impeller. The upper fixed seat is threadedly connected to the lower fixed seat and abuts against the other side of the impeller, thereby fixing the impeller. The upper fixed seat is fixed to the servo motor by vacuum adsorption, which facilitates automatic separation of power after fixing and prevents the impeller fixing mechanism from affecting dynamic balance testing and dynamic balance correction.

[0023] The invention is further configured to include a material handling mechanism mounted on a base to move the impeller from the feeding mechanism to the testing mechanism. The material handling mechanism includes a pneumatic gripper, a gripper mounting plate for mounting the pneumatic gripper, a rotary cylinder for rotating the gripper mounting plate, and a lifting cylinder for moving the gripper mounting plate up and down. The gripper mounting plate is provided with two mutually perpendicular arms. There are two pneumatic grippers, and the two pneumatic grippers are respectively fixed at the ends of the two arms.

[0024] Through the above technical solution, the lifting cylinder drives the gripper mounting plate to move up and down, and the rotating cylinder drives the gripper mounting plate to rotate, thereby enabling the pneumatic gripper to clamp the impeller to each mechanism; there are two pneumatic grippers, which pick up and put down materials simultaneously, improving the efficiency of the equipment.

[0025] The present invention is further configured to include a feeding mechanism disposed on one side of the impeller fixing mechanism. The feeding mechanism includes a feeding chute, a sorting swing rod disposed along the length of the feeding chute, and a rotary cylinder for driving the sorting swing rod to rotate. The discharge end of the feeding chute is provided with a qualified product discharge sensor and a non-qualified product discharge sensor.

[0026] Through the above technical solution, the classification swing arm divides the material feeding chute into two parts: a qualified product area and a non-qualified product area. The impeller is distinguished by the swing of the classification swing arm. If the balance cannot be achieved after multiple corrections, it moves to the non-qualified product area. The qualified product feeding sensor and the non-qualified product feeding sensor indicate that the finished product box is full based on the number of products passing through, and compare the number of non-qualified products to improve the efficiency of the equipment.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. By setting up a testing mechanism, a dynamic balancing correction mechanism, and an angle recognition component, testing and correction are both automated. Multiple corrections can be performed to achieve impeller balance. The testing mechanism does not need to remove the impeller for correction, which improves the efficiency of the equipment and the quality of the impeller.
