Description

Technical Field

[0001] This utility model relates to the field of stator core manufacturing process equipment technology, specifically to a stator core marking device. Background Technology

[0002] The stator core of an electric motor is the core component of the motor, and it is made by stacking a number of core laminations. The typical manufacturing process of a stator core is as follows: first, silicon steel sheets are stamped into core laminations, and then the core laminations are stacked and formed into a stator core assembly by partial welding or riveting in a mold.

[0003] After the stator core is manufactured, data such as batch number, production date, material grade, part number, and key dimensions need to be engraved on the core surface using QR codes or plain text codes for traceability. This process of marking the stator core surface is called coding. Depending on the customer's requirements, coding may need to be done in multiple locations on the stator core. Typically, coding is done simultaneously on the top, bottom, and sides of the stator core.

[0004] In existing technology, stator core marking is performed on a specialized laser marking machine. The laser marking machine's worktable is equipped with a positioning fixture. During operation, the operator places the stator core onto the fixture and turns on the laser marking machine to imprint the required information onto the stator core surface using laser engraving. Typically, stator cores are mass-produced. If marking is required on the top, bottom, and side surfaces of the stator core, three laser marking machines are usually needed, along with three operators, to sequentially mark the top, bottom, and side surfaces of the stator core to complete the marking operation.

[0005] However, the above-mentioned marking method has the disadvantages of high equipment cost, positioning tooling cost and personnel cost due to the increased number of equipment, tooling and personnel. In addition, the marking efficiency is low because the workpiece (stator core) needs to spend time turning around between marking equipment and positioning on each equipment. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes a stator core marking device, aiming to automate the marking process and thereby improve its efficiency. The specific technical solution is as follows: A stator core marking device includes a lifting and rotating platform for positioning the stator core and a core marking main unit for marking the stator core. The core marking main unit includes a vertical main frame disposed next to the lifting and rotating platform, a core end face marking mechanism disposed at the upper part of the vertical main frame, a vertical auxiliary frame disposed adjacent to the vertical main frame, and a core side face marking mechanism disposed on the vertical auxiliary frame. The vertical main frame is also provided with a core flipping mechanism for flipping the stator core to achieve double end face marking of the stator core.

[0007] Preferably, the core end face marking mechanism includes a first lifting cylinder mounted vertically on the upper part of the side of the lifting and rotating platform on the vertical main frame, and an end face laser marking terminal set at the lower piston rod end of the first lifting cylinder, wherein the laser emission direction of the end face laser marking terminal is downward pointing towards the upper end face of the stator core.

[0008] Preferably, the stator core flipping mechanism includes a rotary actuator mounted on the vertical main frame and positioned below the laser-etched end face, and a finger cylinder mounted at the front end of the horizontal rotating shaft of the rotary actuator for picking up and placing the stator core. The finger cylinder is provided with a pair of arc-shaped fingers adapted to the outer edge of the stator core.

[0009] Preferably, the rotary actuator is a stepper motor.

[0010] As a further improvement, the stator core marking device of this utility model is further provided with an end face scanning detection mechanism for detecting the marking information on the end face of the stator core. The end face scanning detection mechanism includes a first horizontal telescopic cylinder mounted on the vertical main frame and an end face scanning detector mounted at the front end of the telescopic rod of the first horizontal telescopic cylinder. The detection probe of the end face scanning detector points downward toward the upper end face of the stator core. The working position of the end face scanning detector is located between the end face laser marking terminal and the finger cylinder, and the end face scanning detector can be retracted into the vertical main frame by the retraction action of the telescopic rod of the first horizontal telescopic cylinder.

[0011] The movable indentation setting of the end face scanning detector described above can avoid interfering with the marking operation of the laser marking dock located above.

[0012] Preferably, the iron core side marking device includes a second lifting cylinder vertically mounted on the vertical auxiliary main frame on the side of the lifting and rotating platform, and a side laser marking terminal set at the piston rod end of the second lifting cylinder, wherein the laser emission direction of the side laser marking terminal is horizontally pointed to the side of the stator iron core.

[0013] To improve the safety of the marking operation, the side laser marking station is equipped with two workstations on the vertical auxiliary main frame. The two workstations include a marking workstation for marking the side of the stator core and a safety workstation for shielding the laser emitted by the side laser marking station. A safety guard plate is installed on the vertical auxiliary main frame. The side laser marking station can be moved to the marking workstation and the safety workstation by the drive of the second lifting cylinder. When the side laser marking station moves to the safety workstation, the marking laser of the side laser marking station is blocked by the safety guard plate.

[0014] As a further improvement, the stator core marking device of this utility model is also provided with a side scanning detection mechanism for detecting the marking information on the side of the stator core. The side scanning detection mechanism includes a second horizontal telescopic cylinder mounted on the vertical sub-frame and a side scanning detector mounted on the front end of the telescopic rod of the second horizontal telescopic cylinder. The detection probe of the side scanning detector points horizontally to the side of the stator core.

[0015] By installing a second horizontal telescopic cylinder on the vertical sub-frame, the position of the side scanning detector can be automatically adjusted to the optimal distance from the side of the stator core, thereby obtaining clearer and more accurate marking information.

[0016] In this utility model, the lifting and rotating platform includes a fixed turntable mounting frame, a lifting plate that is movable in the vertical direction and positioned above the turntable mounting frame, and a servo turntable that is rotatably mounted on the lifting plate and driven by a servo rotary motor; a core mounting plate for positioning the stator core is fixed on the servo turntable.

[0017] The upper end of the iron core mounting plate is provided with a positioning stop for positioning the inner hole of the stator iron core.

[0018] As a preferred embodiment, the stator core marking device of this utility model is further provided with a mounting chassis, wherein the vertical main frame, the vertical auxiliary frame and the turntable mounting frame are respectively fixed on the mounting chassis.

[0019] In this utility model, the lifting plate is moved vertically along a number of guide columns and positioned above the turntable mounting frame. A servo electric push rod is erected on the mounting base below the turntable mounting frame, and the upper end of the telescopic rod of the servo electric push rod is connected to the lifting plate.

[0020] Preferably, the first lifting cylinder, the second lifting cylinder, the first horizontal extension cylinder, and the second horizontal extension cylinder are dual-axis cylinders or multi-axis cylinders.

[0021] In order to realize the automatic operation of stator core marking, the stator core marking device of this utility model is also equipped with a control system for automatically controlling the various functional components (such as various cylinders, servo rotary motors, laser marking terminals, scanning detectors, rotary actuators and telescopic cylinders, etc.) in the stator core marking device.

[0022] To further improve the automation of stator core marking, a transport device for picking up and placing stator cores is also provided next to the stator core marking device. The transport device automatically places the stator cores directly onto the core mounting plate of the lifting and rotating platform of the stator core marking device. After marking is completed, the stator cores are automatically removed, thereby realizing continuous marking operations under batch marking conditions.

[0023] Preferably, in order to provide sufficient operating space for the handling device used for picking up and placing the stator core, the vertical main frame and the vertical auxiliary frame are arranged close to each other in the circumferential direction relative to the rotation center of the lifting and rotating platform.

[0024] The coding method of the stator core coding device of this utility model includes the following steps: (1) Preparation: Turn on the control system of the stator core marking device, move the core mounting plate of the lifting and rotating platform up and down to the lowest position, move the end face scanning detector of the end face scanning detection mechanism back up to the retracted position, move the side laser marking head of the core side marking mechanism up and down to the position blocked by the safety protection baffle, open the arc-shaped finger on the finger cylinder of the core flipping mechanism to the maximum position, move the end face laser marking head of the core end face marking mechanism up to the highest position, and move the side scanning detector of the side scanning detection mechanism back up to the limit position. (2) Workpiece loading: The stator core is installed and positioned on the positioning stop of the core mounting plate by the handling device installed next to the stator core marking device to achieve center positioning; (3) Synchronous coding of the two stator terminals: The control system drives the lifting and rotating platform to rise a certain distance, so that the stator core rises to the coding station; at the same time, the control system simultaneously activates the core end face coding mechanism and the core side coding mechanism, so that the end face laser coding terminal moves down to the preset coding position, and the side laser coding terminal moves up and down until the safety protection baffle is exposed and reaches the preset coding position. The end face laser coding terminal and the side laser coding terminal work synchronously, and in conjunction with the rotation of the lifting and rotating platform, the upper end face and the side face of the stator core are simultaneously coded. (4) Dual-scanning head synchronous scanning detection: After synchronous coding is completed, the control system drives the lifting and rotating platform to continue to rise a certain distance, so that the stator core rises to the scanning station; at the same time, the control system synchronously drives the end face laser marking terminal of the core end face coding mechanism and the side laser marking terminal of the core side coding mechanism to move upward to the highest position, and the side laser marking terminal moves vertically to the position blocked by the safety protection baffle; then, the control system synchronously drives the end face scanning detector of the end face scanning detection mechanism and the side scanning detector of the side scanning detection mechanism to move. The system operates by moving the end face scanning detector horizontally to the scanning station (at which point the end face scanning detector is positioned above the stator core and has a pre-set scanning distance between it and the upper end face of the stator core), and the side scanning detector horizontally to the scanning station (at which point the side scanning detector has a pre-set scanning distance between it and the side of the stator core). Once in position, the end face scanning detector and the side scanning detector are driven to work synchronously. In conjunction with the rotation of the lifting and rotating platform, the system achieves synchronous scanning and reading of the coding information on the upper end face and the side of the stator core, preventing defective products with missing or duplicate codes from flowing into the next process.

[0025] Preferably, when it is also necessary to mark the lower end face of the stator core and detect the marked information, the following steps are also included: (5) Marking the lower end face of the stator core: After the dual scanning heads complete the synchronous scanning and detection, the control system drives the core flipping mechanism to move, so that the finger cylinder of the core flipping mechanism clamps the stator core; at the same time, the control system drives the end face scanning detector of the end face scanning detection mechanism to retract and reset, and the side scanning detector of the side scanning detection mechanism to retract and reset; then, the control system drives the lifting and rotating platform to descend, so that the lower end face of the stator core disengages from the core mounting plate on the lifting and rotating platform; then, the control system drives the rotary actuator of the core flipping mechanism to move, so that The stator core is rotated 180 degrees. Once in position, the control system drives the lifting plate of the rotating platform to rise a certain distance, thus positioning the stator core on the lifting plate. After reaching the desired position, the control system drives the lifting plate of the rotating platform to rise a further distance, raising the stator core to the marking station. Simultaneously, the marking mechanism on the end face of the core is activated, causing the laser marking tool on the end face to move downward to the preset marking position. The laser marking tool on the end face is then activated, and in conjunction with the rotation of the rotating platform, marking is achieved on the upper end face of the rotated stator core (i.e., the lower end face of the original stator core). (5) Scanning and detection of the lower end face of the stator core: After the coding of the lower end face of the stator core is completed, the control system drives the lifting plate of the lifting and rotating platform to continue to rise a certain distance, so that the stator core rises to the scanning station; at the same time, the control system synchronously drives the end face laser marking terminal of the core end face coding mechanism and the side laser marking terminal of the core side coding mechanism to move upward to the highest position, and the side laser marking terminal moves vertically to the position blocked by the safety protection baffle; then, the control system drives the end face scanning detector of the end face scanning detection mechanism to move horizontally to the scanning station (at this time, the end face scanning detector is located above the stator core and has a preset scanning distance between it and the upper end face of the stator core). After it is in position, the end face scanning detector is driven to work, and in conjunction with the rotation of the lifting and rotating platform, the coding information of the upper end face of the flipped stator core (i.e. the lower end face of the original stator core) is scanned and detected.

[0026] The beneficial effects of this utility model are: First, the stator core marking device of this utility model integrates a core end face marking mechanism and a core side marking mechanism on the core marking host, and cooperates with a lifting and rotating platform to realize the automation of the marking operation and improve the efficiency of the marking operation.

[0027] Secondly, the stator core coding device of this utility model has a reasonable layout and setting to realize the integrated operation of coding and scanning detection, and enables end face coding and side coding to be performed simultaneously, as well as end face scanning detection and side scanning detection, thereby further improving the efficiency of coding operation and ensuring the clarity and accuracy of coding information.
