Description

Technical Field

[0001] This utility model relates to the field of medal laser calibration technology, specifically to an automatic medal alignment laser calibration mechanism. Background Technology

[0002] A medal laser marking mechanism is an automated device that uses laser technology to achieve high-precision marking, positioning, or information marking on the surface of medals. It is widely used in the mass production or personalized customization of medals (such as gold, silver, bronze medals and various commemorative medals), and can achieve high-precision etching or marking of information such as text, patterns, numbers, and QR codes.

[0003] Existing medal laser calibration mechanisms require manual placement under the laser calibrator for calibration. Manually handling the calibrator cannot ensure accurate alignment, thus failing to guarantee that each medal is calibrated in the same position, which affects the synchronization of calibration. Therefore, this application proposes an automatic alignment laser calibration mechanism for medals. Utility Model Content

[0011] As a preferred embodiment of this utility model, the bottom of the movable plate is slidably connected to the top of the base plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This automatic medal alignment laser calibration mechanism uses a support column and through holes to place and position multiple medals. A servo motor drives a lead screw to rotate, which in turn drives a slider to slide along the inner wall of a straight groove. This moves a moving plate and the medals to the bottom of the laser calibrator. A laser sensor scans the contour of the medals to ensure precise alignment between the laser calibrator and the medals, achieving automatic alignment and calibration without manual intervention. Furthermore, it ensures the synchronization of the calibration positions of multiple medals.

[0014] This automatic medal alignment laser calibration mechanism drives a stepper motor to rotate the drive wheel, which in turn uses a transmission belt to transmit force to the driven wheel, causing the turntable to rotate at different angles. This allows medals in different positions to be moved under the laser sensor, enabling batch calibration. Simultaneously, pressing the connecting plate allows the through holes to pass through multiple support columns, exposing the medals directly and making it easier for staff to remove the calibrated medals without the need for auxiliary tools.

[0022] Please see Figure 1-5 An automatic medal alignment laser calibration mechanism includes a base plate 1. A servo motor 7 is mounted on the outer side of the base plate 1. A lead screw 8 is fixedly connected to the power output shaft of the servo motor 7. A slider 9 is threadedly connected to the outer edge of the lead screw 8. A movable plate 11 is mounted on the top of the slider 9. A driven wheel 12 and a driving wheel 13 are rotatably connected to the top of the movable plate 11. A transmission belt 14 is sleeved on the inner wall of the driven wheel 12 and the driving wheel 13. The output shaft of a stepper motor 15 is fixedly connected to the top of the driving wheel 13. A turntable 16 is fixedly fixed to the top of the driven wheel 12. One end of a pressure spring 17 is fixedly connected to the top of the turntable 16, and the other end of the pressure spring 17 is fixedly connected to a connecting plate 18. Multiple through holes 19 are evenly opened through the top of the connecting plate 18. Multiple lifting columns 20 are evenly fixedly installed on the top of the turntable 16, and each of the multiple lifting columns 20 is equipped with a limit pin 21.

[0023] In a preferred embodiment, a bracket 2 is mounted on the top of the base plate 1, a cylinder 3 is mounted on the top of the bracket 2, a laser calibrator 4 is fixedly connected to the output shaft of the cylinder 3, and a laser sensor 5 is mounted on the bottom of the bracket 2, the laser sensor 5 corresponding to the position of one of the lifting columns 20.

[0024] In the above structure, the drive cylinder 3 drives the laser calibrator 4 to move downwards to calibrate the medal placed on top of the support column 20. Then, the laser sensor 5 can be used to scan the outline of the medal's position to ensure that the laser calibrator 4 and the medal are accurately aligned.

[0025] In a preferred embodiment, a straight groove 6 is provided on the top of the base plate 1, and a track bar 10 is installed on the inner wall of the straight groove 6. The track bar 10 and the slider 9 are slidably connected. The outer ring of the bearing is fixed on the inner wall of the straight groove 6, and the end of the lead screw 8 away from the servo motor 7 is rotatably connected to the inner ring of the bearing.

[0026] In the above structure, the track bar 10 can be used to limit the slider 9 moving inside the straight groove 6, which can further ensure that the slider 9 moves stably and parallel inside the straight groove 6, thereby adjusting the position of the moving plate 11. At the same time, the bearing can be used to limit the lead screw 8 when rotating, ensuring that it will not easily swing or shift its position when rotating.

[0027] In a preferred embodiment, a motor frame is mounted on the top of the movable plate 11, and the stepper motor 15 is fixedly mounted to the outside of the motor frame.

[0028] In the above structure, the motor frame can be used to position the movable plate 11, ensuring its stable installation on the outside of the base plate 1 and its stability during operation.

[0029] In a preferred embodiment, the positions of the lifting column 20 and the through hole 19 correspond to each other, and the outer diameter of the lifting column 20 is adapted to the inner diameter of the through hole 19.

[0030] The above structure allows medals to be placed on the inner wall of the through hole 19, and the supporting column 20 can be used to support the medals. The rope hole of the medal can be connected to the outside of the limiting pin 21 to limit the medals, ensuring that all medals are set at the same angle inside the through hole 19, and ensuring that the medals are all in the same position when they are marked.

[0031] In a preferred embodiment, a controller is mounted on the bottom of the base plate 1, and the stepper motor 15, the controller, and the laser sensor 5 are electrically connected.

[0032] In the above structure, the laser sensor 5 can scan the outline of the medal's position in real time. The controller can then control the stepper motor 15 to operate, which in turn drives the drive wheel 13 to rotate. The transmission belt 14 can then transmit force to the driven wheel 12, causing the turntable 16 to rotate at an angle. This allows medals at different positions to be moved below the laser sensor 5.

[0033] In a preferred embodiment, the bottom of the movable plate 11 is slidably connected to the top of the base plate 1;

[0034] In the above structure, when the lead screw 8 rotates, it can drive the slider 9 to slide on the inner wall of the straight groove 6, so that the moving plate 11 can slide against the top of the base plate 1, thereby adjusting the position of the equipment above the moving plate 11.

[0035] Working principle: In use, the medals to be calibrated are first placed on top of multiple support columns 20, so that the medals can be set inside the through holes 19, and the rope holes of the medals can be set inside the limiting pins 21 for positioning. Then, the servo motor 7 is driven to drive the lead screw 8 to rotate, and the lead screw 8 drives the slider 9 to slide on the inner wall of the straight groove 6, moving the moving plate 11 and the medals to below the laser calibrator 4. The laser sensor 5 performs contour scanning on the position of the medals, thereby ensuring that the laser calibrator 4 and the medals are accurately aligned, achieving automatic alignment. Then, the cylinder 3 is driven to move the laser calibrator 4 downward to laser the medals. The calibration process can drive the stepper motor 15, which in turn drives the drive wheel 13 to rotate. The transmission belt 14 then transmits force to the driven wheel 12, causing the turntable 16 to rotate at different angles. This allows medals at different positions to be moved below the laser sensor 5, enabling batch calibration. Simultaneously, pressing the connecting plate 18 allows the through hole 19 to pass through multiple support columns 20, exposing the medals directly. This makes it easier for staff to remove the calibrated medals without the need for auxiliary tools. The elastic force of the pressing spring 17 pushes the connecting plate 18 to be positioned above the support columns 20, allowing the through hole 19 to limit the position of the medals during calibration.
