Description

Technical Field

[0001] This application relates to the technical field of stator marking detection, and in particular to a stator laser marking detection device. Background Technology

[0002] As a core component of motors, motor stators are commonly marked with QR codes, serial numbers, and other identifiers on their surface to facilitate production batch management, product traceability, and quality control. They are also equipped with online testing processes to identify defective products such as those with missing, duplicate, or fuzzy codes.

[0003] Currently, automated coding and inspection production lines typically consist of multiple units working together, including a receiving platform, a transfer mechanism, a coding structure, an inspection mechanism, and a unloading mechanism. The overall process flow is as follows: an external feeder transports the product to the receiving platform, the transfer mechanism transfers the product to the coding structure for laser coding, the transfer mechanism then transfers the product to the inspection mechanism for inspection, and the unloading mechanism sorts and discharges qualified and unqualified products.

[0004] The existing marking structure has poor versatility, only adapting to a single type of stator. It cannot simultaneously accommodate stator products of different structures (A and B) and marking methods. Product A requires multi-angle rotation marking, while product B requires marking on the top surface. Furthermore, the clamping methods of the two products are different, requiring two sets of tooling for clamping and positioning. Therefore, when changing products, the tooling must be changed simultaneously, which takes a lot of time. This is especially true when small batches of the two products are produced interchangeably, further extending the marking and inspection time. As a result, it is difficult to adapt to the production needs of automated high-speed mass production lines. Summary of the Invention

[0005] To meet the requirements of automated high-speed mass production lines, this application provides a stator laser marking and inspection device.

[0006] This application provides a stator laser marking and inspection device, which adopts the following technical solution: A stator laser marking and inspection device includes a receiving platform, a transfer mechanism, a marking structure, a visual inspection mechanism, and a unloading mechanism. The marking structure includes: The coding machine is mounted on the machine body; The conversion base is slidably mounted on the machine body and is equipped with a mounting base; A rotating base, rotatably mounted on a mounting base; The coding fixture is set on the rotating seat; Clamping component one is set on coding fixture one and used to clamp and position product A; A rotating assembly is used to drive the rotating seat to rotate, causing product A to rotate toward the coding machine and enabling coding to be applied to the surface of product A at different angles. The second coding fixture is horizontally slidably mounted on the conversion seat; Clamping component two is set on coding fixture two and is used to clamp and position product B; The moving component is used to drive the movement of the second coding fixture; When coding product A, the conversion seat moves and drives the coding fixture one to align with the transfer mechanism, placing product A onto the coding fixture one. The clamping component one clamps product A, and the rotating seat rotates while the conversion seat moves to achieve coding of product A. When coding product B, the conversion seat moves and drives the fixture two to align with the moving mechanism, placing product B onto the coding fixture two. The clamping component two clamps and positions product B, and the coding fixture two moves and drives product B to move, achieving coding of product B.

[0007] By adopting the above technical solution, the feeding device places product A or product B on the receiving platform. The sensor on the receiving platform can detect whether product A or product B is placed there. The transfer mechanism starts to pick up the product on the coding structure and place it on the vision inspection mechanism. At the same time, the product on the receiving platform is picked up and placed on the coding structure for coding.

[0008] If product B is to be marked, the conversion seat moves and drives the marking fixture two to align with the marking machine. The transfer mechanism then places product B on the marking fixture two. The clamping component two starts to clamp and position product B. The moving component starts to drive the marking fixture two and product B to move to different positions. The marking machine starts to mark product B. Then the transfer mechanism continues to start.

[0009] If it is product A, the conversion seat moves and drives the coding fixture 1 to align with the coding machine, which allows the transfer mechanism to place product A onto the coding fixture 1. The clamping component 1 is activated to clamp and position product A. The rotating seat rotates and drives the coding fixture 1 and product A closer to the coding machine. At the same time, the conversion seat can also move to cooperate, making it easier for the coding machine to code at the required position on product A. After coding is completed, the conversion seat drives the coding fixture 1 to move and the rotating seat drives the coding fixture 1 to rotate, so that the coding fixture 1 moves back and rotates to its original position for accurate product placement in the future.

[0010] After coding, the products are moved to the vision inspection mechanism for testing. Product B has its coding position on the top, while product A has its coding position on the side. Therefore, the vision inspection mechanism detects the different coding positions of the two products. The unloading mechanism separates and transports qualified and unqualified products according to the detection structure. Thus, the coding detection of the two products is integrated, which improves the convenience of detecting two different products, eliminates the need for manual tooling changes, improves detection efficiency, and meets the requirements of automated high-speed mass production lines.

[0011] Since the transfer mechanism needs to move the product from the coding structure to the vision inspection mechanism, and simultaneously move the product from the receiving platform to the coding structure, the distance between the two gripping components of the moving mechanism remains unchanged. Therefore, when changing between products A and B, the gripping components have difficulty adapting to the different positions of coding fixture one and coding fixture two during the gripping process. Therefore, by moving the conversion seat, coding fixture one or coding fixture two can be aligned with the coding machine, and coding inspection can be completed without changing the structure of the transfer mechanism, further improving inspection efficiency and meeting the requirements of automated high-speed mass production lines. At the same time, the multiple structures in this application can be shared during the coding inspection process, thereby greatly reducing equipment costs and requiring less floor space.

[0012] Optionally, the length direction of the mounting base is parallel to the rotation direction of the rotating base and forms a non-zero angle with the sliding direction of the conversion base. When product A is placed on the coding fixture one and product B is placed on the coding fixture two, their length directions are parallel and parallel to the sliding direction of the conversion base.

[0013] By adopting the above technical solution, the rotating seat drives product A to approach the coding machine for coding, which increases the range of coding positions and improves adaptability. At the same time, the length directions of A and B are the same and parallel to the transplanting direction, which makes the posture uniform during the grasping and conveying process, reduces grasping errors, improves positioning stability, and improves the efficiency and quality of the coding and detection process.

[0014] The sliding directions of the rotating seat and the conversion seat form an angle, causing the mounting seat to be in an inclined state. The end of the mounting seat closest to the coding fixture is located outside the coding fixture and the rotating seat, thus leaving space so that the rotation of the rotating seat and the movement of the coding fixture do not interfere with each other. The structure is compact and stable, and the size of the equipment is reduced.

[0015] Optionally, the clamping assembly includes a clamping group one and a clamping group two located on different sides of product A. The clamping group one cooperates to clamp and position the surface of product A, and the clamping group two presses against product A for positioning.

[0016] By adopting the above technical solution, the product surface is clamped and pressed against the upper surface of the product for positioning, thereby achieving better product positioning, improving the clamping and positioning effect, and improving the coding and inspection quality; at the same time, it can be adapted to A products of different sizes, with good clamping flexibility and strong versatility; and by dispersing stress through multi-point clamping, the deformation of thin-walled stators is reduced, ensuring product quality.

[0017] Optionally, the receiving platform, transplanting mechanism, coding structure, visual inspection mechanism, and unloading mechanism are all spaced apart along the length of product A, and the transplanting mechanism includes: The movable base is slidably mounted on the machine body along the length of product A; Two lifting seats are spaced apart along the sliding direction of the moving seat and are vertically slidably installed on the moving seat; Two gripping components are set on two lifting seats and can grip either product A or product B. They first grip the product located on the receiving platform and the coding structure simultaneously, and then move the product to the coding structure and the vision inspection mechanism respectively.

[0018] By adopting the above technical solution, the receiving, transfer, coding, vision, and unloading processes are linearly arranged along the length of the product. This allows the transfer mechanism to simultaneously grab two products and place two products at opposite ends, making the gripping and conveying process more stable and improving coding and inspection efficiency and quality. Simultaneously, the linear layout ensures clear material flow and the shortest path, reducing idle travel and increasing cycle time. A single movement completes the process of "picking up the product from the upper station and placing it at the lower station," doubling transfer efficiency and eliminating waiting time. Same-direction sliding ensures coaxiality of gripping / placement, minimizing positioning errors and improving coding / inspection consistency, further enhancing coding and inspection efficiency and quality. Furthermore, the gripping component can grip either product A or product B as needed, further improving coding efficiency and quality.

[0019] Optionally, the grasping component includes: A three-jaw cylinder, a clamping cylinder one, and a clamping cylinder two are spaced apart on a movable base. The three-jaw cylinder and the clamping cylinder one work together to clamp product B, or the three-jaw cylinder and the clamping cylinder two work together to clamp product A.

[0020] By adopting the above technical solution, the three-jaw cylinder is used to clamp the irregular arc sections of products A and B. When using product A, clamping cylinder one releases, and clamping cylinder two clamps the regular section of product A. Conversely, when using product B, clamping cylinder two releases, and clamping cylinder one clamps the regular section of product A. This allows for the coordinated clamping and positioning of products A and B, and enables simultaneous clamping and positioning of both irregular and regular product positions. This improves the stability of product conveying, making product conveying faster and better, and enhancing the efficiency and quality of coding and inspection.

[0021] Optionally, the visual inspection mechanism includes: The detection seat is slidably mounted on the machine body along the moving direction of the conversion seat; Inspection fixture one and inspection fixture two are set at intervals on the inspection seat and are used for placing and positioning products A and B, respectively. A side-mounted inspection camera is used to inspect the coding on product A. The top-mounted inspection camera is used to inspect the coding on product B.

[0022] By adopting the above technical solution, side coding (A) is detected by a side inspection camera, and top coding (B) is detected by a top inspection camera, ensuring accurate detection with no missed detections. The sliding switching fixture of the inspection seat is synchronized with the coding cycle, eliminating waiting time and improving overall efficiency. The dedicated camera faces the coding surface directly, with no angular deviation, resulting in high recognition accuracy and low false positive rate. It can easily realize the detection and transportation of two types of products, improving coding detection efficiency and quality.

[0023] Optionally, the feeding mechanism includes: The gantry frame is mounted on the machine body; The first unloading platform is horizontally slidably mounted on the gantry frame, and the top surface detection camera is mounted on the first unloading platform. The second unloading platform is vertically slidably installed on the first unloading platform; Conveyor lines and NG material channels are spaced out on the machine body; The feeding assembly is used to clamp and convey product A or product B, placing qualified products onto the conveyor line and non-qualified products onto the NG feed channel for conveying.

[0024] By adopting the above technical solution, the top-side camera is integrated into the unloading platform. Therefore, after the top-side camera completes its inspection, the unloading component can more quickly and effectively pick up the product and place it on the conveyor line or NG (Not From Good) channel for transport, thereby further improving the coding and inspection efficiency. Horizontal and vertical sliding covers the entire workstation range, and the unloading trajectory is flexible and adaptable to different unloading positions. Precise sorting avoids material mixing, reduces manual sorting costs, and improves yield traceability.

[0025] Optionally, the rotating assembly includes: Rotating component, used to drive the conversion seat to rotate; A limiter is mounted on the conversion seat and electrically connected to the rotating component. When the conversion seat rotates to a horizontal position, it abuts against the limiter and controls the conversion seat to stop rotating.

[0026] By adopting the above technical solution, the rotating component starts and drives the conversion seat to rotate. The rotation of the conversion seat adjusts the angle of product A so that the angle can be adapted to the coding machine for coding. After coding is completed, the rotating component starts and drives the conversion seat to rotate back and abut against the limiter for positioning. The conversion seat stops rotating and rotates back to a horizontal state, which makes it easier to accurately place the product on the coding fixture two, thus improving the coding detection efficiency and quality.

[0027] Optionally, the moving component includes: The movable component is set on the second coding fixture. A fixed plate is mounted on the conversion seat and connected to the piston rod of the moving part. The piston of the moving part drives the marking fixture two to move.

[0028] By adopting the above technical solution, the extension and retraction of the piston rod of the moving part can drive the movement of the marking fixture 2.

[0029] Optionally, it also includes a smoking structure, the smoking structure comprising: A smoking machine and a smoking pipe, wherein the smoking pipe is installed in the smoking machine and extends to the side of the coding machine and sucks up smoke and dust under the action of the smoking machine.

[0030] By adopting the above technical solution, the smoke and dust generated during coding are absorbed and treated, reducing the risk of environmental pollution.

[0031] In summary, this application includes at least one of the following beneficial technical effects: 1. By aligning the coding fixture two with the coding machine via the conversion seat, the moving component initiates the movement of product B, and the coding machine starts coding product B. Alternatively, the conversion seat drives the coding fixture one to align with the coding machine, and the rotating seat and conversion seat drive product A to rotate and move, and the coding machine starts coding. After coding, the product is moved to the vision inspection mechanism for inspection, and the unloading mechanism separates and transports qualified and unqualified products. Therefore, the coding and inspection of two types of products are integrated, thereby improving the convenience of inspecting two different products, eliminating the need for multiple manual tooling changes, improving inspection efficiency, and meeting the requirements of automated high-speed mass production lines.

[0032] 2. By moving the conversion seat, either coding fixture one or coding fixture two can be aligned with the coding machine. Coding inspection can be completed without changing the structure of the transfer mechanism, which further improves the inspection efficiency and meets the requirements of automated high-speed mass production lines. At the same time, the multiple structures in this application can be shared in the coding inspection process, which can greatly reduce equipment costs and reduce the footprint.

[0036] This application discloses a stator laser marking detection device.

[0037] Reference Figures 1-7 The stator laser marking and inspection device includes a receiving platform 11, a transfer mechanism 4, a marking structure 2, a vision inspection mechanism 5, and a unloading mechanism 6. The loading device places product A or B onto the receiving platform 11 for positioning. The loading device can be a robotic arm, etc. The transfer mechanism 4 starts to pick up the product located on the marking structure 2 and place it onto the vision inspection mechanism 5 for inspection. At the same time, the product located on the receiving platform 11 is picked up and placed onto the marking structure 2 for marking. The loading device starts to replenish the receiving platform 11. The unloading mechanism 6 separates qualified and unqualified products according to the inspection structure of the vision inspection mechanism 5 and transports them separately.

The angle is designed according to actual conditions and can be any one of 30 degrees, 40 degrees, or 45 degrees.

[0041] The rotating seat 23 is located inside the mounting seat 15 and is rotatably mounted on the opposite side walls of the mounting seat 15. The rotation axis of the rotating seat 23 is parallel to the length direction of the mounting seat 15. The coding fixture 1 24 is fixedly mounted on the upper surface of the rotating seat 23.

The sliding direction is perpendicular to the sliding direction of the conversion seat 22, and the sliding direction is along the direction of approaching or moving away from the coding machine 21. When product A is placed on the coding fixture 1 24, the coding fixture 1 24 is inserted and mounted on the ring section, and the extension section is inserted and mounted on the coding fixture 1 24 for positioning. At this time, the length direction of product A is parallel to the sliding direction of the conversion seat 22. The connection method between product B and the coding fixture 2 25 is the same as the connection method when product A is placed on the coding fixture 1 24. At this time, the length direction of product B is parallel to the sliding direction of the conversion seat 22.

[0042] Clamping component 3 is mounted on coding fixture 24 and is used to clamp and position product A. Rotating component 36 is used to drive rotating seat 23 to rotate, so that product A rotates toward coding machine 21 and can be coded on the surface of product A at different angles. Clamping component 35 is mounted on coding fixture 25 and is used to clamp and position product B. Moving component 37 is used to drive coding fixture 25 to move.

[0046] After product A is placed on the coding fixture 24 for positioning, two clamping components 311 and 33 are activated simultaneously, driving two clamping plates 312 to press against the side wall of product A for positioning, and two clamping plates 34 to press against the upper surface of product A for positioning, thereby achieving the positioning of product A. Clamping assembly 35 is mounted on the coding fixture 25 and has the same structure as clamping assembly 32. Clamping assembly 35 presses against the upper surface of product B for positioning.

[0047] The rotating assembly 36 includes a rotating component 361 and a limiter 362. The rotating component 361 is a rotary cylinder. The rotating component 361 is fixedly installed on the side wall of the mounting base 15, and its output shaft is connected to the rotating base 23 and used to drive the rotating base 23 to rotate. At the same time, the limiter 362 is fixedly installed on the inner side wall of the mounting base 15. The rotating component 361 is controlled to start and stop by the control box 14. When the rotating base 23 rotates to a horizontal state, it abuts against the limiter 362. The limiter 362 sends a trigger signal to the control box 14, and the control box 14 controls the rotating component 361 to stop driving the rotating base 23 to rotate and positions the rotating base 23.

[0050] Two sensors that are electrically connected to the control box 14 are fixedly installed on the receiving platform 11. When the sensor detects that product A is placed on the coding fixture 1 24, the control box 14 controls the corresponding structure of product A to start.

Each gripping component 43 includes a three-jaw cylinder 44, a clamping cylinder 1 45, and a clamping cylinder 2 46, spaced apart along the length of the machine body 1 on the lower surface of the lifting seat 42. The three-jaw cylinder 44 is used to clamp and position the outer wall of the annular section; the clamping cylinder 1 45 or the clamping cylinder 2 46 is used to clamp and position the extended section. Since the length of product A is greater than the length of product B, the three-jaw cylinder 44 and the clamping cylinder 1 45 cooperate to clamp product B, with the clamping cylinder 2 46 in an open state; alternatively, the three-jaw cylinder 44 and the clamping cylinder 2 46 cooperate to clamp product A, with the clamping cylinder 1 45 in an open state.

The drive source can be an electric actuator. The inspection fixture 1 52 and the inspection fixture 2 53 are spaced apart on the upper surface of the inspection base 51 along its moving direction. The inspection fixture 1 52 has the same structure as the coding fixture 1 24 and is used to position product A. The inspection fixture 2 53 has the same structure as the coding fixture 2 25 and is used to position product B.

[0054] The side inspection camera 54 is fixedly mounted on the machine body 1 and is used to inspect the coding quality of product A.

[0055] The unloading mechanism 6 includes a gantry frame 61, unloading platform 1 62, unloading platform 2 63, a conveyor line 64, an NG material channel 65, and an unloading assembly 7. The gantry frame 61 is fixedly installed on the machine body 1 and extends above the inspection fixture 1 52 and the inspection fixture 2 53. The unloading platform 1 62 is horizontally slidably installed on the top of the gantry frame 61, and the sliding direction is perpendicular to the sliding direction of the inspection seat 51, and it is in a vertical state. The unloading platform 2 63 is vertically slidably installed on the side wall of the unloading platform 1 62, and a drive source for driving the movement of the unloading platform 1 62 is fixedly installed on the gantry frame 61. At the same time, a drive source for driving the vertical movement of the unloading platform 2 63 is fixedly installed on the side wall of the unloading platform 1 62. Both drive sources are electric push rods. The top surface inspection camera 55 is fixedly installed on the side wall of the unloading platform 1 62 and is set vertically downward, and is used to inspect the coding quality on the top of product B.

[0056] The conveyor line 64 and the NG channel 65 are fixedly installed on the machine body 1. The conveyor line 64 conveys qualified products along the moving direction of the detection seat 51, and the NG channel 65 conveys unqualified products along the moving direction perpendicular to the moving direction of the detection seat 51. The above structures are all existing technologies and will not be described in detail here. The unloading component 7 is used to clamp and convey product A or product B, and to place qualified products on the conveyor line 64 and unqualified products on the NG channel 65 for conveying. The structure of the unloading component 7 is the same as that of the gripping component 43 and will not be described in detail here.

[0057] The working principle of this application embodiment is as follows: The feeding device places product A onto receiving fixture 12 or product B onto receiving fixture 23. When the sensor detects the presence of product A, the conversion seat 22 moves to align coding fixture 24 with the coding machine 21. The moving seat 41 drives one gripping component 43 to align with receiving fixture 12 and the other gripping component 43 to align with coding fixture 24. The lifting seat 42 moves downward, and one gripping component 43 grips product A located on receiving fixture 12. One gripping component 43 grips the already-coded product A located on the coding fixture 24. After the lifting seat 42 moves upward, the moving seat 41 moves horizontally, so that one gripping component 43 is aligned with the coding fixture 24, and the other gripping component 43 moves to be aligned with the inspection fixture 52. The lifting seat 42 moves downward, and one gripping component 43 places product A on the coding fixture 24, while the other gripping component 43 places product A on the inspection fixture 52, thereby realizing the conveying of product A.

[0058] Clamping component 3 clamps and positions product A, rotating component 36 drives product A to rotate, and conversion seat 22 moves horizontally to adjust the position of product A. Coding machine 21 starts to code the side wall of product A. After coding is completed, conversion seat 22 and rotating seat 23 drive product A to move back and rotate to its original position. Clamping component 3 releases the clamp, thus completing the coding of product A.

[0059] The detection seat 51 moves to drive product A, and the side detection camera 54 starts to detect the coding quality of product A to determine whether it is a qualified product. If it is a qualified product, the gripping component 43 places product A on the conveyor line 64. Otherwise, if it is unqualified, the gripping component 43 places product A on the NG channel 65, thereby realizing the coding detection of product A.

[0060] When the sensor detects that product B is placed, the conversion seat 22 moves to drive the coding fixture 25 to align with the coding machine 21, and the transfer mechanism 4 clamps and conveys product B. During conveying, the gripping component 43 aligns with product B and clamps and conveys product B, and the conveying method is the same as the method used when conveying product A.

[0061] Clamping component 2 35 clamps and positions product B. Moving component 37 drives tooling 2 and product B to move. Coding machine 21 starts coding product B. After coding, clamping component 2 35 releases the clamp, thus completing the coding process for product B. Inspection seat 51 moves product B, and top-side inspection camera 55 checks the coding quality of product B. Gripping component 43 places qualified product B onto conveyor line 64, or places unqualified product B onto NG feeder 65, thus achieving coding inspection of product B without requiring multiple manual tooling changes, improving inspection efficiency and meeting the requirements of automated high-speed mass production lines.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
