Description

Technical Field

[0001] This utility model relates to the technical field of rotor testing equipment for motors, and more particularly to an automatic full-inspection machine for rotors. Background Technology

[0002] In the field of motor rotor testing, traditional testing equipment generally suffers from single function and low degree of automation. Although a roundness testing device disclosed in a motor rotor testing equipment can automatically detect runout, it lacks multi-dimensional testing functions such as weight and appearance, and still requires manual assistance to complete the full-item testing. Although a brushless DC motor stator and rotor testing platform integrates weight and size detection, its clamping mechanism relies on manual adjustment of the threaded rod for positioning, which limits the testing efficiency and cannot achieve automatic sorting after testing. The existing technology also has the following pain points: (1) the scattered testing process leads to low efficiency; (2) manual operation is prone to errors; (3) lack of multi-parameter comprehensive judgment and intelligent sorting capabilities. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and to provide an automatic full inspection machine for rotors.

[0004] The objective of this utility model is achieved through the following technical solution: An automatic rotor full inspection machine includes a frame, a loading robot, a vision inspection mechanism, a roundness inspection mechanism, a weight inspection mechanism, a rotor transport mechanism, and a sorting mechanism. The loading robot and the sorting mechanism are respectively installed at both ends of the frame. The vision inspection mechanism, the roundness inspection mechanism, and the weight inspection mechanism are located between the loading robot and the sorting mechanism. The vision inspection mechanism, the roundness inspection mechanism, and the weight inspection mechanism are connected through the rotor transport mechanism. The loading robot is connected to the vision inspection mechanism, and the weight inspection mechanism is connected to the sorting mechanism. This automatic rotor full inspection machine can detect the appearance, roundness, and weight of rotors, and can accurately classify them, improving work efficiency and reducing human error.

[0005] A better alternative is a vision inspection mechanism comprising a vision inspection base, a sensor mounting base, a vision sensor, a detection mounting column, and a first rotor positioning seat. The vision inspection base is mounted on the frame. The vision sensor is connected to the vision inspection base via the sensor mounting base. The first rotor positioning seat is connected to the first rotor positioning seat via the detection mounting column. The first rotor positioning seat corresponds to the vision sensor, the loading robot, and the rotor handling mechanism, respectively. This vision inspection mechanism can automatically detect the appearance of the rotor, avoiding human error and preventing defective products from flowing into the next process.

[0006] A better alternative is that the roundness detection mechanism includes a roundness detection structure and a rotor pressing structure, both of which are mounted on the frame. The detection end of the roundness detection structure corresponds to the rotor pressing structure and the rotor transport mechanism, respectively. This roundness detection mechanism can automatically position and fix the rotor, and automatically detect the roundness of the rotor without human intervention, thus improving detection accuracy and work efficiency.

[0007] A better alternative is the roundness detection structure, which includes a ring gauge, a rotor support plate, a guide column, a ring gauge fixing column, a vertical lifting plate, a lifting cylinder fixing plate, and a rotor lifting cylinder. The ring gauge is connected to the vertical lifting plate via the ring gauge fixing column. The vertical lifting plate is connected to the telescopic rod of the rotor lifting cylinder. The rotor lifting cylinder is mounted on the frame via the lifting cylinder fixing plate. The upper end of the guide column is connected to the rotor support plate, and the lower end of the guide column passes through the rotor support plate and connects to the lifting cylinder fixing plate. The ring gauge is matched with both the rotor pushing structure and the rotor handling mechanism. This roundness detection structure can automatically detect the roundness of the rotor without human intervention, improving work efficiency and avoiding misjudgments of product status.

[0008] A better alternative is a rotor pressing structure comprising a rotor pressing cylinder, a pressing bracket, a longitudinal pressing guide rail, a guide block, a longitudinal sliding base, a buffer spring, and a push rod. The rotor pressing cylinder and the guide block are both mounted on the frame via the pressing bracket. The longitudinal sliding base is slidably connected to the guide block via the longitudinal pressing guide rail. The telescopic rod of the rotor pressing cylinder is connected to the longitudinal sliding base. The push rod is slidably connected to the longitudinal sliding base. The buffer spring is sleeved on the push rod. The push rod matches the roundness detection structure. This rotor pressing structure can automatically fix the rotor for positioning, facilitating rotor roundness detection.

[0009] A preferred embodiment includes a weight detection mechanism comprising a weight detection bracket, an electronic scale, and a second rotor positioning seat. The second rotor positioning seat is mounted on top of the electronic scale, which is mounted on the frame via the weight detection bracket. The second rotor positioning seat is matched with both the rotor conveying mechanism and the sorting mechanism. This weight detection mechanism can automatically detect the weight of the rotor.

[0010] A better alternative is a sorting mechanism comprising a sorting robot, a qualified product discharge line, a waste product discharge line, and a defective product discharge line. The weight detection mechanism is connected to the qualified product discharge line, the waste product discharge line, and the defective product discharge line via the sorting robot. The qualified product discharge line and the waste product discharge line are both connected to the frame, and the defective product discharge line is connected to the waste product discharge line. This sorting mechanism can accurately distinguish rotors in different states, avoiding material mixing, reducing worker workload, and improving work efficiency.

[0011] A better alternative is a defective product discharge line comprising a grouping base, guide grooves, isolation rods, a push plate, and a lateral pushing cylinder. The lateral pushing cylinder is mounted on the defective product discharge line via the grouping base. The isolation rods divide the top of the grouping base into multiple guide grooves, each corresponding to a sorting robot. The isolation rods are slidably connected to the push plate, which is connected to the telescopic rod of the lateral pushing cylinder. This defective product discharge line can isolate defective products without human intervention, preventing mixing of defective products.

[0012] A better alternative is a rotor handling mechanism comprising a vertical lifting cylinder, a cylinder mounting bracket, a lifting slide rail, a vertical lifting seat, a sorting longitudinal moving cylinder, a longitudinal moving base, and longitudinal clamping jaws. The vertical lifting cylinder is mounted on the frame via the cylinder mounting bracket. The telescopic rod of the vertical lifting cylinder is connected to the vertical lifting seat. The vertical lifting seat is slidably connected to the cylinder mounting bracket via the lifting slide rail. The longitudinal moving base is slidably connected to the vertical lifting seat. The sorting longitudinal moving cylinder is mounted on the vertical lifting seat. The telescopic rod of the sorting longitudinal moving cylinder is connected to the longitudinal moving base. The longitudinal clamping jaws are evenly distributed on the longitudinal moving base and are respectively matched with the vision inspection mechanism, the roundness inspection mechanism, and the weight inspection mechanism. This rotor handling mechanism enables rotor switching between the vision inspection mechanism, the roundness inspection mechanism, and the weight inspection mechanism, allowing for unmanned inspection processes, thereby improving the accuracy of rotor inspection results and reducing the labor intensity of personnel.

[0013] A better alternative is a loading robot comprising a loading bracket, a loading linear module, a vertical telescopic cylinder, and rotor grippers. The fixed end of the loading linear module is mounted to the frame via the loading bracket, and the rotor grippers are connected to the lateral end of the loading linear module via the vertical telescopic cylinder. The rotor grippers are matched with the vision inspection mechanism. This loading robot enables automatic rotor loading without human intervention, reducing labor intensity and improving the accuracy of appearance inspection.

[0014] This utility model has the following advantages and beneficial effects compared to the prior art:

[0015] This utility model achieves fully unmanned operation through a frame, a feeding robot, a vision inspection mechanism, a roundness inspection mechanism, a weight inspection mechanism, a rotor handling mechanism, and a sorting mechanism, improving inspection efficiency by more than 3 times. It can make comprehensive judgments and automatically sort based on the data obtained from appearance inspection, roundness inspection, and weight inspection, with a sorting accuracy rate of 99.8%.

The lifting cylinder fixing plate 416 is mounted on the frame 1, and the rotor lifting cylinder 417 is mounted below the lifting cylinder fixing plate 416. The telescopic rod of the rotor lifting cylinder 417 is connected to the bottom center of the vertical lifting plate 415.

The upper ends of the four guide posts 413 pass through the four corners of the vertical lifting plate 415 and connect to the bottom of the rotor support plate 412. The four guide posts 413 are slidably connected to the vertical lifting plate 415. The top of the vertical lifting plate 415 is vertically connected to the lower ends of two ring gauge fixing posts 414, each ring gauge fixing post 414 being located between two guide posts 413. The upper ends of the ring gauge fixing posts 414 pass through the rotor support plate 412 and connect to the ring gauge 411.

The vertical lifting plate 415 is used to drive the ring gauge fixing column 414 to move upward. The lifting cylinder fixing plate 416 is used to fix the rotor lifting cylinder 417 on the frame 1. The rotor lifting cylinder 417 provides power for the movement of the ring gauge 411 relative to the rotor 8. The rotor pressing cylinder 421 provides power for the push rod 427 to move in the vertical direction c. The push bracket 422 is used to install the guide block 424, push rod 427, and rotor push cylinder 421.

[0040] The vertical lifting cylinder 601 provides power for the lifting of the longitudinal gripping jaws 608. The cylinder mounting bracket 602 secures the vertical lifting cylinder 601. The lifting slide rail 603 guides the vertical lifting base 604. The vertical lifting base 604 securely mounts the sorting longitudinal moving cylinder and two longitudinal slide rails 605.

The sorting robot 71 sorts the rotors 8 according to information from the vision detection mechanism 3, the roundness detection mechanism 4, and the weight detection mechanism 5, and transfers various types of rotors 8 to different discharge lines. The qualified product discharge line 72 is used to transport qualified rotors 8 and transfer them to the next process. The scrap product discharge line 73 is used to transport defective rotors 8. The defective product discharge line 74 distinguishes between rotors 8 that are not up to standard in appearance, roundness, and weight, making it easier for maintenance personnel to classify and repair them.

[0042] like Figure 9 As shown, the sorting robot 71 includes a sorting bracket 711, a sorting linear module 712, a sorting vertical movement cylinder 713, and a sorting gripper 714.

The sorting gripper 714 is used to clamp the rotor 8 and place it on different discharge lines.

[0043] like Figure 10 As shown, the qualified product discharge line 72 includes a wire pull bracket 721, a conveyor line 722, and multiple positioning clamps 723. The wire pull bracket 721 is fixedly connected to the right end of the frame 1. The conveyor line 722 is installed on top of the wire pull bracket 721, and the multiple positioning clamps 723 are all installed on the conveyor belt of the conveyor line 722, and the multiple positioning clamps 723 are evenly distributed.

[0044] like Figure 11As shown, the defective product discharge line 74 includes a grouping base 741, four guide slots 742, eight isolation rods 743, a push plate 744, and a transverse push cylinder 745. The grouping base 741 is installed on the rear side of the waste product discharge line 73. The transverse push cylinder 745 is installed on the left end of the grouping base 741. The eight isolation rods 743 divide the top of the grouping base 741 into four guide slots 742. All eight isolation rods 743 pass through the rod slots of the push plate 744 and are slidably connected to the push plate 744. The left side of the push plate 744 is connected to the telescopic rod of the transverse push cylinder 745.

[0045] The working process of the automatic rotor full inspection machine is as follows: The rotor 8 goes through feeding, appearance inspection, roundness inspection and weight inspection in sequence, and then is sorted and unloaded into the next process.

[0046] Loading: Under the action of the loading linear module 202, the rotor gripper 204 moves to directly above the rotor 8 whose appearance is to be inspected. The vertical telescopic cylinder 203 drives the rotor gripper 204 to move vertically downward, clamping the rotor 8 to be inspected. Then, under the action of the vertical telescopic cylinder 203, the rotor gripper 204 moves upward, and the loading linear module 202 drives the rotor gripper 204 to move to directly above the first rotor positioning seat 305 of the vision inspection mechanism 3. Driven by the vertical telescopic cylinder 203, the rotor gripper 204 places the rotor 8 to be inspected into the first rotor positioning seat 305.

[0047] Appearance Inspection: The vision sensor 303 begins to acquire the appearance of the rotor 8 to be inspected on the first rotor positioning seat 305, and uploads the acquired image data to the controller for judgment. A good appearance indicates a qualified product; otherwise, it is a defective product. Driven by the vertical lifting cylinder 601, the longitudinal clamping jaw 608 moves to the front of the rotor 8 whose roundness is to be inspected. Under the action of the sorting longitudinal movement cylinder, the rotor 8 to be inspected moves backward in the horizontal longitudinal direction b, and the longitudinal clamping jaw 608 clamps the rotor 8. Under the action of the sorting longitudinal movement cylinder, the longitudinal clamping jaw 608 retracts backward in the horizontal longitudinal direction b. Under the action of the vertical lifting cylinder 601, the longitudinal clamping jaw 608, holding the rotor 8 to be inspected, moves to the front of the roundness detection structure 41. Under the action of the sorting longitudinal movement cylinder, the longitudinal clamping jaw 608 places the rotor 8 to be inspected onto the rotor support plate 412 of the roundness detection structure 41.

[0048] Roundness Inspection: Rotor push cylinder 421 drives push rod 427 to press downwards towards the top of rotor 8 in the vertical direction c. Under the action of buffer spring 426, push rod 427 cushions the impact on rotor 8, preventing damage to its appearance. Rotor support plate 412 and push rod 427 clamp the upper and lower ends of the rotor 8 to be inspected. Ring gauge 411 is fitted onto the lower end of rotor 8. At this time, the telescopic rod of rotor lifting cylinder 417 drives vertical lifting plate 415 to move upwards in the vertical direction c. Vertical lifting plate 415, through ring gauge fixing post 414, drives ring gauge 411 to move upwards relative to rotor 8 in the vertical direction c, moving ring gauge 411 from the lower end to the upper end of rotor 8. When the infrared sensor detects that ring gauge 411 has successfully moved to the top of rotor 8, rotor 8 is determined to be a qualified product; otherwise, it is a defective product. The infrared sensor then feeds back the detection data to the controller. The rotor lifting cylinder 417 drives the vertical lifting plate 415 to descend. Under the drive of the ring gauge fixing column 414, the ring gauge 411 also moves downward in the vertical direction c relative to the rotor 8 to be tested. The rotor pushing cylinder 421 drives the push rod 427 to move upward in the vertical direction c, and the push rod 427 releases the rotor 8 after the roundness test is completed. Under the combined action of the vertical lifting cylinder 601 and the sorting longitudinal movement cylinder, the rotor 8 to be tested is transferred from the rotor support plate 412 of the roundness detection structure 41 to the second rotor positioning seat 503 of the weight detection mechanism 5.

[0049] Weight Detection: Electronic scale 502 weighs the rotor 8 to be tested. If the rotor 8 is within the standard range, it is qualified; otherwise, it is defective. Sorting grippers 714 move to directly above the second rotor positioning seat 503 of the weight detection mechanism 5. The sorting vertical movement cylinder 713 drives the sorting grippers 714 to move downwards in the vertical direction c and clamp the tested rotor 8. Based on the judgment results from the visual inspection mechanism 3, roundness inspection mechanism 4, and weight detection mechanism 5, different types of rotors 8 are placed onto the qualified product discharge line 72, the scrap product discharge line 73, and the defective product discharge line 74, respectively. The qualified product discharge line 72 transports qualified rotors 8 to the next process. The scrap product discharge line 73 transfers the scrap rotors 8 to the material box. When the rotor 8 is present at the feed end of the guide groove 742 of the defective product discharge line 74, the transverse push cylinder 745 drives the push plate 744 to push to the right in the horizontal transverse a, pushing the rotor 8 to the right end of the guide groove 742, so that the sorting robot 71 can subsequently put the rotor 8 into the guide groove 742.

Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
