Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, and in particular to an automatic stator and rotor testing machine. Background Technology

[0002] In the field of motor manufacturing, the stator and rotor are core components, and their dimensional accuracy and conformity directly determine the performance and quality of the motor. Therefore, automated and high-precision inspection of the stator and rotor before assembly is a crucial part of the production process, among which the detection of foreign object defects such as burrs, expansion and contraction, and deformation in the external contour is particularly critical.

[0003] Currently, the industry commonly uses manual visual inspection or simple mechanical go / no-go gauges to screen the external contours of stators and rotors. Manual inspection is inefficient, easily affected by subjective factors, and its stability and consistency are difficult to guarantee. While conventional go / no-go gauges can determine whether specific dimensions are within limits, their ability to judge complex shape features such as the continuity and smoothness of the contour is limited. They are unable to effectively identify slight deformations or irregular foreign matter attachments, easily leading to misjudgments or missed detections.

[0004] Existing technologies rely on mechanical tools with a single detection principle, which are insufficient for identifying complex shape defects and have the technical drawback of low detection efficiency. Utility Model Content

[0005] The main purpose of this invention is to propose an automatic stator and rotor inspection machine, which aims to solve the technical problem that the existing technology, which relies on mechanical tools with a single detection principle, has insufficient ability to identify complex shape defects and has low detection efficiency.

[0006] To achieve the above objectives, this utility model proposes an automatic stator and rotor testing machine, comprising:

[0007] Stator feeding device, used to receive and transport stators;

[0008] Rotor feeding device, used to receive and transport rotors;

[0009] The frame has stator testing lines and rotor testing lines arranged side by side. Both stator and rotor testing lines include:

[0010] The shaping device is located downstream of the stator feeding device and the rotor feeding device, and is used to perform high-precision shaping on the stator or rotor.

[0011] The height detection mechanism, located downstream of the shaping device, is used to detect the height of the stator or rotor after shaping.

[0012] The rotary positioning mechanism is located downstream of the height detection mechanism and is used to clamp and rotate the stator or rotor to a predetermined angle.

[0013] The foreign object detection mechanism is located downstream of the rotary positioning mechanism. The foreign object detection mechanism includes a foreign object detection driving component, a foreign object gauge connected to the foreign object detection driving component, and a detection and judgment component. The foreign object detection driving component is used to drive the foreign object gauge to move toward the stator or rotor to match and detect its outline. The detection and judgment component is configured to determine whether the workpiece shape is qualified based on the feedback signal during the process of the foreign object detection driving component driving the foreign object gauge to move downward.

[0014] The go / stop detection mechanism is located downstream of the foreign object detection mechanism and is used to detect the bore or shaft diameter of the stator or rotor.

[0015] Furthermore, the detection and judgment component is a pressure sensor, which is configured to detect the pressure value when the foreign object detection drive component drives the foreign object gauge to move downward and press against the workpiece. If the pressure value exceeds the preset range, the workpiece is judged to be unqualified in shape.

[0016] Furthermore, the rotor feeding device includes a rotor slide and a rotor distributing mechanism. The rotor distributing mechanism is connected to the rotor slide and includes a rotor distributing seat, a fixed platform, and a running mechanism. The rotor distributing seat is located on the fixed platform and can rotate relative to the fixed platform. The running mechanism is located below the fixed platform and is configured to drive the rotor distributing seat to move in the horizontal direction, thereby connecting the rotor distributing seat to the frame.

[0017] Furthermore, the rotor distributing mechanism also includes a flipping mechanism for flipping the aforementioned rotor distributing seat. The flipping mechanism is fixedly connected to the rotor distributing seat and is located above the running mechanism.

[0018] Furthermore, the flipping mechanism includes a gear, a rotating rod, a rack, and a flipping drive component. The rotating rod is fixedly connected to the rotor distribution seat, one end of the rotating rod is connected to the gear, the gear is movably mounted on the rack, and the rack is connected to the flipping drive component for transmission. The flipping mechanism is configured such that the flipping drive component drives the rack to move linearly, thereby causing the gear to rotate and drive the rotating rod to flip the rotor distribution seat.

[0019] Furthermore, the running mechanism includes a running slider, a running guide rail, a connecting plate, and a running drive component. The running slider is slidably connected to the running guide rail and fixedly connected to the fixed platform. The connecting plate is located between the rotor distribution seat and the running drive component, and the running drive component is connected to the rotor distribution seat through the connecting plate.

[0020] Furthermore, both the stator feeding device and the rotor feeding device are equipped with a transfer mechanism between the stator testing line and the rotor testing line, respectively.

[0021] Furthermore, the transfer mechanism includes a transfer section and a gripping section. The gripping section can move along a preset trajectory of the transfer section. The gripping section is configured such that after gripping the material at the bottom, the entire part is moved by a structure connected to the transfer section.

[0022] Furthermore, the shaping device includes a shaping drive component, a shaping mold, and a shaping transfer mechanism. The shaping transfer mechanism includes a slide table and a transfer component, which is used to drive the slide table to perform linear motion in at least two mutually perpendicular directions.

[0023] Furthermore, the transmission component includes a first conveying component and a second conveying component. The first conveying component drives the slide to move back and forth relative to the assembly line direction, while the second conveying component drives the slide to move left and right relative to the assembly line direction.

[0024] This utility model's technical solution includes stator and rotor inspection lines arranged in parallel. Each inspection line is sequentially equipped with a shaping device, a height detection mechanism, a rotation positioning mechanism, a foreign object detection mechanism, and a pass / stop detection mechanism. Specifically, the foreign object detection mechanism drives a foreign object gauge towards the workpiece through a foreign object detection drive component, and uses a pressure sensor to monitor the pressure feedback during the movement, thereby intelligently determining whether the stator or rotor's external contour is qualified. This solution integrates automatic feeding, shaping, and inspection, effectively solving the problem of insufficient ability to identify complex shape defects in existing technologies that rely on manual or single-tool inspection. This utility model has the beneficial effect of high inspection efficiency. Attached Figure Description

[0048] It should be noted that in this utility model, some of the structures corresponding to certain processes are existing technologies, such as the height detection mechanism 5 and the rotary positioning mechanism 6. These existing technologies can be implemented using conventional and mature structures in the field, and are not the focus of this utility model's improvement; therefore, they will not be described in detail. Furthermore, the driving components of this utility model generally employ cylinders and servo motors, which can be selected according to the objective circumstances.

[0049] In some embodiments of this utility model, the detection and judgment component 73 is a pressure sensor. The pressure sensor is configured to detect the pressure value when the foreign object detection driving component 71 drives the foreign object gauge 72 to move downward and press against the workpiece. If the pressure value exceeds the preset range, the workpiece shape is judged to be unqualified.

[0050] In some embodiments of this utility model, the rotor feeding device 2 includes a rotor slide 21 and a rotor distributing mechanism 22. The rotor distributing mechanism 22 is connected to the rotor slide 21, and the rotor distributing mechanism 22 includes a rotor distributing seat 221, a fixed platform 222 and a running mechanism 223. The rotor distributing seat 221 is disposed on the fixed platform 222 and can rotate relative to the fixed platform 222. The running mechanism 223 is disposed below the fixed platform 222 and is configured to drive the rotor distributing seat 221 to move in the horizontal direction, thereby connecting the rotor distributing seat 221 to the frame 3.

[0051] Specifically, the rotor distributing mechanism 22 also includes a flipping mechanism 224 for flipping the aforementioned rotor distributing seat 221. The flipping mechanism 224 is fixedly connected to the rotor distributing seat 221 and is located above the running mechanism 223.

[0052] Specifically, the flipping mechanism 224 includes a gear 2241, a rotating rod 2242, a rack 2243, and a flipping drive component 2244. The rotating rod 2242 is fixedly connected to the rotor distribution seat 221. One end of the rotating rod 2242 is connected to the gear 2241. The gear 2241 is movably mounted on the rack 2243. The rack 2243 is connected to the flipping drive component 2244 in a transmission manner. The flipping mechanism 224 is configured such that the flipping drive component 2244 drives the rack 2243 to move linearly, thereby causing the gear 2241 to rotate and drive the rotating rod 2242 to flip the rotor distribution seat 221.

[0053] Specifically, the running mechanism 223 includes a running slider 2231, a running guide rail 2232, a connecting plate 2233, and a running drive component 2234. The running slider 2231 is slidably connected to the running guide rail 2232 and fixedly connected to the fixed platform 222. The connecting plate 2233 is located between the rotor distribution seat 221 and the running drive component 2234. The running drive component 2234 is connected to the rotor distribution seat 221 through the connecting plate 2233.

[0054] Specifically, the rotor slide 21 includes a sliding section 211 and a horizontal section 212. After the rotor descends through the sliding section 211, it enters the rotor distribution seat 221 through the horizontal section 212. More specifically, the horizontal section 212 includes an abutment wall 2121 and guide bars 2122. The abutment wall 2121 limits the rotor from the side, while the guide bars 2122 guide the movement of the rotor from below. The guide bars 2122 can be arranged in various forms. In some preferred embodiments of this utility model, a plurality of (e.g., two) guide bars 2122 are provided below the abutment wall 2121 to balance the force on the rotor, making the movement of the rotor more stable.

[0055] In some embodiments of this utility model, the rotor feeding device 2 further includes a signal sensor 23, which is configured to detect whether a rotor is in position on the rotor distribution seat 221. Specifically, a plate frame 24 is provided on the side of the rotor distribution seat, and the signal sensor 23 is located on the plate frame 24.

[0056] In some embodiments of this utility model, the stator feeding device 1 and the rotor feeding device 2 are respectively provided with a transfer mechanism 9 between the stator detection line 31 and the rotor detection line 32.

[0057] Specifically, the transfer mechanism 9 includes a transfer section 91 and a gripping section 92. The gripping section 92 can move along a preset trajectory of the transfer section 91. The gripping section 92 is configured such that after gripping material at the bottom, the entire part is moved by a structure connected to the transfer section 91. Understandably, the gripping section 92 is a robotic arm. The construction of the robotic arm parts for gripping the stator and rotor is different; please refer to the prior art for details.

[0058] In some embodiments of this utility model, the shaping device 4 includes a shaping drive component 41, a shaping mold 42, and a shaping transmission mechanism 43. The shaping transmission mechanism 43 includes a slide table 431 and a transmission component 432. The transmission component 432 is used to drive the slide table 431 to perform linear motion in at least two mutually perpendicular directions.

[0059] Specifically, the transmission component 432 includes a first conveying component 4321 and a second conveying component 4322. The first conveying component 4321 drives the slide table 431 to move back and forth relative to the assembly line direction, while the second conveying component 4322 drives the slide table 431 to move left and right relative to the assembly line direction.

[0060] More specifically, the first conveying assembly 4321 includes a first slider 43211 and a first guide rail 43212, and the first conveying assembly 4321 is disposed at both ends of the slide table 431. The second conveying assembly 4322 includes a second slider 43221 and a second guide rail 43222, and the second conveying assembly 4322 is disposed below the slide table 431.

[0061] The following content serves as an explanation of the working principle of this utility model:

[0062] Workpieces (stator and rotor) enter the inspection line through their respective feeding devices. The stator feeding device 1 can use a conveyor belt for transport, while the rotor feeding device 2 preferably includes a rotor feeding mechanism 22 with a splitting and flipping function. This mechanism can separate and position the rotor from the rotor slide 21, and flip it to the required posture before accurately feeding it into the inspection station via the running mechanism 223. On the inspection line, the workpiece first passes through the shaping device 4, which uses a shaping drive component 41 (such as a cylinder or servo motor) to drive the upper mold to shape the workpiece in the height direction. The shaping and conveying mechanism 43 below it can accurately position the workpiece. After shaping, the workpiece is sent to the height detection mechanism 5, where a displacement sensor accurately measures its height. Subsequently, the rotation positioning mechanism 6 presses the workpiece and rotates it, aligning specific features (such as keyways, wiring holes, etc.) with the next station. Then, it enters the critical foreign object detection mechanism 7: the foreign object detection drive component 71 (such as a cylinder) drives a foreign object gauge 72 designed according to the shape of the qualified workpiece to move downwards, attempting to fit or conform to the workpiece. During this process, the pressure sensor integrated in the drive unit monitors pressure changes in real time. If the workpiece shape is acceptable, the foreign object gauge 72 will smoothly reach its position, and the pressure value will be within the preset normal range. If there are defects such as burrs or deformation, it will cause obstruction of movement or excessive clearance, resulting in abnormal pressure values ​​(too high or too low). Based on this, the system automatically determines it to be a defective product. Finally, the workpiece reaches the go / no-go detection mechanism 8, where standard go and no-go gauges are used to perform a final inspection of its inner hole or outer diameter. After the entire inspection is completed, qualified products flow out, and unqualified products are rejected and sent to the defective product box.

[0063] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
