[0024] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant drawings. Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] Combined with Figures 1-4 As shown, a sample classification mechanism of a laser marking machine includes:

[0027] A mounting bracket 1, which is a rectangular metal frame and is provided with a substrate 11 at the bottom. A plurality of openings 12 are arranged at the center of the top surface of the substrate 11, and the plurality of openings 12 are arranged at intervals in the longitudinal direction. A material guiding plate 13 is provided below each opening 12, and a storage box 14 is provided at the bottom of the material guiding plate 13;

[0028] A conveying assembly 2, which is arranged on the top surface of the substrate 11 and is used to convey the marked sample parts so that they can be directly conveyed to the corresponding storage boxes 14 through different openings 12 on the top surface of the substrate 11 for sub-packaging;

[0029] The clamping assembly 3 is arranged on the top of the conveying assembly 2, and is used to clamp and fix the sample piece, so as to convey it to the top of the designated opening 12, and then release it, and form a positioning and conveying structure with the conveying assembly 2;

[0030] The controller 4, which can be a Siemens S7-1200 or other model controller 4, is set on the mounting frame 1, and the conveying component 2 and the clamping component 3 are remotely controlled by the Bluetooth technology inside the controller, so that the entire classification mechanism can be operated automatically.

[0031] Specifically; in the present embodiment, the conveying assembly 2 includes a slide groove 21 and a slider 22, wherein the slide groove 21 is arranged on the top surface of the substrate 11, and the slider 22 is slidably assembled on the slide groove 21. In addition, considering the stability during the conveying process, at least two slide grooves 21 should be arranged, so that they are respectively located on both sides of the opening 12 and extend in the longitudinal direction, and the slider 22 has two protrusions protruding downward at the bottom, and is slidably inserted into the two slide grooves 21 respectively.

[0032] The top surface of the slider 22 is set to be rectangular, and a hole larger than the opening 12 should be provided in the center to facilitate the subsequent packaging of the sample pieces. In addition, a loading platform should be left at the end of the substrate 11, that is, one end portion of the substrate 11 is raised upward so that it is close to the bottom surface of the slider 22. When the slider 22 is located at the raised portion, the bottom of the sample piece is attached to the bottom surface of the raised portion so that it is vertically inserted into the hole as a whole.

[0033] In addition, in order to transport the slider 22, a screw rod 23 should be provided inside one of the slide grooves 21, and the two ends of the screw rod 23 should be rotatably connected to the inner wall of the slide groove 21 respectively, and a driving motor 24 is also provided inside the base plate 11, and the output end of the driving motor 24 should be transmission-connected to one end of the screw rod 23, and the screw rod 23 passes through the protruding part of the slider 22 along the direction of the slide groove 21 so that it can be threadedly assembled with the slider 22. When the screw rod 23 rotates, it can drive the slider 22 to move horizontally along the direction of the slide groove 21, so that the holes on the slider 22 can be aligned with each opening 12 in turn.

[0034] The clamping assembly 3 includes a clamping plate 31 arranged on the top surface of the slider 22. A through hole 38 is provided at the center of the top surface of the clamping plate 31. The through hole 38 is exactly the same size as the hole on the slider 22 and is concentrically arranged up and down. At the same time, the four corners of the clamping plate 31 are respectively locked and fixed to the slider 22 by bolts.

[0035] The interior of the clamping plate 31 is hollow, and an adjusting plate 32 is provided inside. The adjusting plate 32 is arranged in a ring shape and sleeved around the periphery of the through hole 38. The top surface of the adjusting plate 32 is provided with a spiral slot, and the inner ring surface of the adjusting plate 32 is movably assembled with the side wall at the through hole 38 by using a ball bearing. Therefore, the adjusting plate 32 can rotate flexibly around the through hole 38.

[0036] In addition, positioning grooves 33 are respectively provided at the four sides of the top surface of the clamping plate 31. In this embodiment, there are 4 positioning grooves 33. During actual use, the number of the positioning grooves 33 can be increased or decreased according to specific requirements. The multiple positioning grooves 33 should be arranged in a circumferential array around the through hole 38. Each positioning groove 33 is internally provided with a clamping block 34. The bottom of the clamping block 34 extends downward and passes through the positioning groove 33 and extends into the interior of the clamping plate 31, and is vertically inserted into the slot downward. Therefore, when the adjusting plate 32 rotates, the arc-shaped inner wall of the slot can be used to force the clamping block 34 to move inward or outward, thereby realizing the function of clamping adjustment.

[0037] The above-mentioned clamping assembly 3 and conveying assembly 2 cooperate with each other to fix the sample piece conveyed onto the clamping plate 31, and then through the horizontal conveying method, the sample piece can be vertically arranged above the corresponding opening 12. At this time, only by reversely driving the adjusting plate 32 to rotate, the clamping block 34 can be loosened, and the sample piece can fall into the designated storage box 14 through the opening 12.

[0038] Based on the above requirements, the driving structure of the adjusting disk should not only be able to drive the adjusting disk in both forward and reverse directions, but also have a self-locking function to prevent the adjusting disk from reversing due to the reverse acting force of clamping and the interference of external factors. Therefore, the structure should be set as a worm gear 35 and worm 36 transmission structure.

[0039] That is, a worm gear 35 is fixedly installed at the bottom of the adjusting disk. A worm 36 is arranged on one side of the worm gear 35, and the worm 36 is in transmission engagement with the worm gear 35. At the same time, a connecting portion is convexly provided on the inner bottom surface of the clamping plate 31. The two ends of the worm 36 are respectively rotationally connected to the connecting portion. Moreover, a servo motor 37 is further provided inside the clamping plate 31, and the output end of the servo motor 37 is in transmission connection with the worm 36.

[0040] Since the clamping part is driven by the worm gear 35 and worm 36, the clamping force on the four sides is the same. Considering various materials of the sample piece, an elastic pad should be provided on the end surface of the clamping block 34 facing the center direction, and anti-slip lines are provided on its surface, so as to increase the friction between the elastic pad and the sample piece and avoid indentations on the surface of the sample piece due to excessive clamping force.

[0041] On the front of the mounting bracket 1, directly above the loading area, there should also be a mounting seat. A lifting adjustment member 5 is provided on this mounting seat. The lifting adjustment member 5 is set as an electric telescopic rod. In this embodiment, this structure can also be replaced by telescopic structures such as a sleeve fixed by a pin and a hydraulic cylinder. The purpose is to adjust its extension length according to sample parts of different heights, so that the scanner 6 provided at the bottom of the lifting adjustment member 5 can identify and classify the marking parts at the top of the sample parts. The scanner 6 can use a Trimble SX10 image scanner 6. The data scanned by it is compared with the pre-stored data, and then the sample parts are classified.

[0042] In the above entire structure, the scanner 6, the drive motor 24, and the servo motor 37 should all be equipped with Bluetooth modules, so as to use the controller 4 to create a Bluetooth client and remotely control and connect each device to the controller 4. At the same time, a PLC single-chip microcomputer should be equipped inside the controller 4 to program it to make the entire operation process automated.

[0043] On the surface of the controller 4, there is also a display screen 41 and control buttons. Inside it, one or more counters are equipped, and the two are electrically connected. The counter is used to record the samples conveyed at each opening 12 respectively, and the values are displayed through the display screen 41, which is convenient for comparing with the number of samples in the storage box 14 during the subsequent inventory process, so that the staff can make statistics.

[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
