Description

[0001] This utility model relates to the field of motor rotor testing technology, and more specifically, to a marking device for motor rotor testing. Background Technology

[0002] A marking device for motor rotor inspection is an automated or semi-automated device specifically designed for auxiliary positioning, marking, and classification during the manufacturing process of motor rotors. Its core function is to precisely mark specific locations on the rotor after detecting a specific type of imbalance or quality defect. For example, the marking device for use on a motor rotor production line, as proposed in publication number "CN216397141U", includes a fixed box, a transmission belt installed inside the fixed box via a transmission mechanism, a fixed frame fixedly mounted on the fixed box, a scanning plate fixedly mounted on the fixed frame, a lifting plate fixedly mounted on the fixed frame via multiple return springs, a marker fixedly mounted on the lower part of the lifting plate, a drive mechanism installed between the fixed frame and the lifting plate, a push frame fixedly mounted on the fixed box, a detection scanning plate fixedly mounted on the push frame, an electric telescopic rod fixedly mounted on the push frame, and a push plate fixedly mounted on the drive end of the electric telescopic rod.

[0003] However, in the above technical solution, the push plate structure used in the marking device is relatively simple and lacks a clamping structure for the motor rotor during the pushing process. This causes the rotor to easily deviate or slip during pushing, making it impossible to accurately and stably push it into the collection slot, thus affecting the accuracy of defective product sorting and collection efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a marking device for motor rotor detection, which can effectively solve the problem that the push plate structure used in the marking device in the background technology is relatively simple and lacks a clamping structure for the motor rotor during the pushing process. This causes the rotor to easily deviate or slip during pushing, making it impossible to accurately and stably push it into the collection slot, thus affecting the accuracy of defective product sorting and collection efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A marking device for testing motor rotor includes a base, a mounting groove is provided on one side of the upper surface of the base, and a conveyor belt is provided at the bottom of the mounting groove;

[0007] A dotting mechanism for dotting is provided on one side of the upper surface of the base;

[0008] A number of support rods are fixedly installed on the other side of the upper surface of the base. A support plate is fixedly installed on the upper end of each support rod. A scanner is provided on the lower surface of the support plate.

[0009] A bracket is fixedly installed on the side of the base near the support rod. A cylinder is fixedly installed at the bottom of the bracket. The output end of the cylinder passes through the bracket and is fixedly installed on a mounting plate. A movable plate is provided on one side of the mounting plate. A clamping component for clamping is provided on the upper surface of the movable plate.

[0010] Preferably, the clamping assembly includes a slide groove, which is formed on one side of the upper surface of the movable plate. Two sliders are slidably disposed in the slide groove, and right-angle brackets are fixedly installed on the upper surfaces of the two sliders. A clamping plate is fixedly installed on the upper surfaces of the two sliders.

[0011] A drive structure for driving the slider is provided on the other side of the upper surface of the movable plate.

[0012] Preferably, the drive structure includes a positioning frame, which is fixedly installed on the other side of the upper surface of the movable plate. A threaded rod is rotatably installed on one side of the top of the positioning frame. A lifting plate is threaded on one side of the threaded rod. Two rotating shafts are rotatably installed on one side of the lifting plate. A rotating rod is fixedly installed at one end of each of the two rotating shafts.

[0013] Both sides of the upper surface of the two sliders are fixedly installed with limit frames, and one end of each of the two rotating rods is rotatably installed between the inner walls of the corresponding limit frames.

[0014] A motor is fixedly installed on one side of the upper surface of the positioning frame, and the upper end of the threaded rod passes through the limiting frame and is fixedly connected to the motor output shaft.

[0015] Preferably, a positioning rod is fixedly installed on the other side of the top of the positioning frame, and the lifting plate is slidably disposed on one side of the positioning rod.

[0016] Preferably, the clamping plate includes two guide plates and an arc-shaped plate. The two guide plates are respectively fixedly installed on both sides of the corresponding arc-shaped plate, with one side of one guide plate being adjacent to the right-angle bracket.

[0017] Preferably, two connecting grooves are formed through one side surface of the mounting plate, and a connecting block is slidably disposed in each of the two connecting grooves. One side of the two connecting blocks is fixedly connected to the moving plate. A vertical rod is fixedly installed between the two sides of the inner wall of the two connecting grooves. The two connecting blocks are slidably disposed on one side of the corresponding vertical rod body, and a spring is sleeved on the other side of the two vertical rods.

[0018] Two connecting brackets are fixedly installed on the side of the movable plate near the cylinder. Ball bearings are rotatably installed at the lower end of both connecting brackets. Composite guide plates are fixedly installed on both sides of the bracket.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) When the defective rotor moves to the front of the clamping assembly along the conveyor belt, the conveyor belt stops, the cylinder on the bracket starts, and pushes the mounting plate and the entire moving plate to move horizontally forward, so that the clamping assembly moves to the position of the rotor. The drive motor of the clamping assembly starts, drives the threaded rod to rotate, and the lifting plate that meshes with the threaded rod moves vertically downward along the positioning rod. The downward movement of the lifting plate is converted into horizontal traction of the two sliders through the rotating shaft and rotating rod, driving the two sliders to slide synchronously and towards each other in the chute, thereby driving the two clamping plates to smoothly approach and clamp the rotor from both sides. After clamping, the cylinder continues to advance, and drives the clamped rotor to move horizontally forward through the mounting plate and moving plate, pushing it away from the conveyor belt and accurately guiding it into the defective collection trough located on one side of the machine base. This effectively avoids the problem of rotor tilting, rolling, slipping or even jamming caused by single-point force in the pushing process of the simple push plate structure, ensuring that the defective rotor can be pushed stably and accurately into the designated collection area in every sorting action, thereby greatly improving the sorting accuracy and reliability.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] like Figures 1-8 As shown, a marking device for testing motor rotor includes a base 1, a mounting groove 2 is provided on one side of the upper surface of the base 1, and a conveyor belt 201 is provided at the bottom of the mounting groove 2.

[0032] A dotting mechanism 3 for dotting is provided on one side of the upper surface of the base 1;

[0033] Several support rods 4 are fixedly installed on the other side of the upper surface of the base 1. Each support rod 4 has a support plate 5 fixedly installed on its upper end. A scanner 501 is provided on the lower surface of the support plate 5.

[0034] A bracket 6 is fixedly installed on the side of the base 1 near the support rod 4. A cylinder 601 is fixedly installed at the bottom of the bracket 6. The output end of the cylinder 601 passes through the bracket 6 and is fixedly installed on the mounting plate 602. A movable plate 603 is provided on one side of the mounting plate 602. A clamping component 7 for clamping is provided on the upper surface of the movable plate 603.

[0035] The clamping assembly 7 includes a slide groove 701, which is formed on one side of the upper surface of the movable plate 603. Two sliders 702 are slidably arranged in the slide groove 701. A right angle bracket 7021 is fixedly installed on the upper surface of each slider 702. A clamping plate 703 is fixedly installed on the upper surface of each slider 702.

[0036] A drive structure 704 for driving the slider 702 to move is provided on the other side of the upper surface of the movable plate 603.

[0037] The drive structure 704 includes a positioning frame 7041, which is fixedly installed on the other side of the upper surface of the movable plate 603. A threaded rod 7042 is rotatably installed on one side of the top of the positioning frame 7041. A lifting plate 7043 is threaded on one side of the threaded rod 7042. Two rotating shafts 7044 are rotatably installed on one side of the lifting plate 7043. A rotating rod 7045 is fixedly installed at one end of each of the two rotating shafts 7044.

[0038] Both sides of the upper surface of the two sliders 702 are fixedly installed with limit frames 7046, and one end of each of the two rotating rods 7045 is rotatably installed between the inner walls of the corresponding limit frames 7046.

[0039] A motor 7047 is fixedly installed on one side of the upper surface of the positioning frame 7041, and the upper end of the threaded rod 7042 passes through the limiting frame 7046 and is fixedly connected to the output shaft end of the motor 7047.

[0040] A positioning rod 7048 is fixedly installed on the other side of the top of the positioning frame 7041, and a lifting plate 7043 is slidably set on one side of the positioning rod 7048.

[0041] The motor rotor to be tested is carried by the conveyor belt 201 and conveyed at a constant speed along the base 1. When the rotor moves to the underside of the marking mechanism 3, the marking mechanism 3 can perform preliminary marking of the rotor based on the primary sensor signal or wait for subsequent instructions. After the preliminary marking or positioning is completed, the rotor continues to move with the conveyor belt 201 to the underside of the support plate 5. The scanner 501, which is fixedly installed on the lower surface of the support plate 5, performs precise scanning of the rotor passing below, collects its key data, and determines whether the rotor is a qualified product. After the data processing system of the scanner 501 identifies the defective rotor, it will send a signal to the control system. When the defective rotor moves with the conveyor belt 201 to the front of the clamping assembly 7, the conveyor belt 201 stops, the cylinder 601 on the bracket 6 starts, and pushes the mounting plate 602 and the entire moving plate 603 to move horizontally forward, so that the clamping assembly 7 moves to the position of the rotor. The drive motor 7047 of the clamping assembly 7 starts, driving the threaded rod 7 042 rotates, and the lifting plate 7043, which meshes with the threaded rod 7042, moves vertically downward along the positioning rod 7048. The downward movement of the lifting plate 7043 is converted into horizontal traction of the two sliders 702 through the rotating shaft 7044 and the rotating rod 7045. This drives the two sliders 702 to slide synchronously and towards each other in the slide groove 701, thereby causing the two clamping plates 703 to smoothly approach and clamp the rotor from both sides. After clamping, the cylinder 601 continues to advance, and through the mounting plate 602 and the moving plate 603, it drives the clamped rotor to move horizontally forward, pushing it away from the conveyor belt 201 and accurately guiding it into the defective product collection groove located on one side of the machine base 1. This effectively avoids the problems of rotor skew, rolling, slipping, or even jamming that are easily caused by single-point force in the pushing process of a simple push plate structure. It ensures that the defective rotor can be pushed stably and accurately into the designated collection area in each sorting action, greatly improving the accuracy and reliability of sorting.

[0042] In another embodiment of the present invention, the clamping plate 703 includes two guide plates 7031 and an arc plate 7032. The two guide plates 7031 are respectively fixedly installed on both sides of the corresponding arc plate 7032, and one side of one guide plate 7031 is connected to the right angle bracket 7021.

[0043] When the two clamping plates 703 move towards each other and approach the rotor, the guide plate 7031 at its front end will contact the outer surface of the rotor before the arc-shaped plate 7032. The inclined guide surface can effectively guide the rotor, which may be slightly misaligned, to axially align, completing the initial correction and positioning. Subsequently, the arc-shaped plate 7032 will then make full contact with the aligned outer surface of the rotor to achieve the final stable and uniform clamping.

[0044] In another embodiment of the present invention, two connecting grooves 8 are opened through one side surface of the mounting plate 602. A connecting block 9 is slidably disposed in each of the two connecting grooves 8. One side of the two connecting blocks 9 is fixedly connected to the moving plate 603. A vertical rod 10 is fixedly installed between the two sides of the inner wall of the two connecting grooves 8. The two connecting blocks 9 are slidably disposed on one side of the corresponding vertical rod 10. A spring 11 is sleeved on the other side of the two vertical rods 10.

[0045] Two connecting brackets 12 are fixedly installed on the side of the movable plate 603 near the cylinder 601. Ball bearings 13 are rotatably installed at the lower end of both connecting brackets 12. Composite guide plates 14 are fixedly installed on both sides of the bracket 6.

[0046] After the clamping assembly 7 completes the horizontal clamping of the rotor, the cylinder 601 continues to advance, driving the mounting plate 602 to move forward. The mounting plate 602 transmits the thrust to the moving plate 603 through the uprights 10 and connecting blocks 9 in the connecting slots 8 on both sides, driving the entire clamping mechanism and the clamped rotor to move forward. During this process, the connecting frame 12 fixed on the moving plate 603 and the ball bearings 13 at its lower end move forward. The ball bearings 13 contact the upper inclined surface of the composite guide plate 14 fixed on both sides of the bracket 6 and roll along it. The upper inclined surface design of the composite guide plate 14 allows the connecting frame 12 and the moving plate 603 to generate an upward vertical displacement along the guide of the uprights 10 while moving horizontally. This allows the bottom of the clamped rotor to completely detach from the surface of the conveyor belt 201 during the removal process, avoiding surface scratches or wear that may be caused by continuous friction between the bottom of the rotor and the surface of the conveyor belt 201 in the traditional pushing method, and greatly protecting the appearance quality of the product.

[0047] The working principle of a marking device for detecting motor rotor:

[0048] In use, the motor rotor to be tested is carried by the conveyor belt 201 and conveyed at a constant speed along the base 1. When the rotor moves to the underside of the marking mechanism 3, the marking mechanism 3 can perform preliminary marking of the rotor based on the primary sensor signal or wait for subsequent instructions. After completing the preliminary marking or positioning, the rotor continues to move with the conveyor belt 201 to the underside of the support plate 5. The scanner 501, fixedly installed on the lower surface of the support plate 5, performs precise scanning of the rotor passing below, collects its key data, and determines whether the rotor is a qualified product. After the data processing system of the scanner 501 identifies the defective rotor, it will send a signal to the control system. When the defective rotor moves with the conveyor belt 201 to the front of the clamping assembly 7, the conveyor belt 201 stops, the cylinder 601 on the bracket 6 starts, and pushes the mounting plate 602 and the entire moving plate 603 to move horizontally forward, so that the clamping assembly 7 moves to the position of the rotor. The drive motor 7047 of the clamping assembly 7 starts, driving the threaded... As rod 7042 rotates, lifting plate 7043, which meshes with threaded rod 7042, moves vertically downward along positioning rod 7048. The downward movement of lifting plate 7043 is converted into horizontal traction of two sliders 702 through rotating shaft 7044 and rotating rod 7045, driving the two sliders 702 to slide synchronously and towards each other in the slide groove 701. This causes two clamping plates 703 to smoothly approach and clamp the rotor from both sides. After clamping, cylinder 601 continues to advance, driving the clamped rotor to move horizontally forward through mounting plate 602 and moving plate 603, pushing it away from conveyor belt 201 and accurately guiding it into the defective product collection groove located on one side of machine base 1. This effectively avoids the problems of rotor skew, rolling, slipping, or even jamming that are easily caused by single-point force in simple push plate structures during the pushing process. It ensures that each sorting action can stably and accurately push the defective rotor into the designated collection area, greatly improving the accuracy and reliability of sorting.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
