[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 3As shown, in the present embodiment, a workpiece flipping mechanism of a laser marking machine comprises a base plate 1, characterized in that: a flipping assembly 5 is installed on one side of the top of the base plate 1, the flipping assembly 5 comprises a mounting plate 501 fixedly connected to the outer wall of the top of the base plate 1, a mounting rod 502 is rotatably connected in the mounting plate 501, a connecting plate 503 is fixedly sleeved on one side of the circumferential outer wall of the mounting rod 502, a positioning rod 504 is slidably inserted at one end of the connecting plate 503, a spring 505 is sleeved on the circumferential outer wall of the positioning rod 504, two ends of the spring 505 are respectively fixedly connected to the positioning rod 504 and the connecting plate 503, a plurality of equally spaced limiting holes 506 are opened on the outer wall of one side of the mounting plate 501, and the positioning rod 504 can enter the plurality of limiting holes 506.

[0025] A connecting frame 2 is coaxially fixed to the outer wall of the other side of the mounting rod 502 , and a rectangular through hole is provided in the middle of the connecting frame 2 .

[0026] Pull the positioning rod 504 outward to make it leave the limiting hole 506. At this time, the connecting plate 503 will not be restricted, and the spring 505 will also be forced to lengthen. Then, by moving the connecting plate 503, the mounting rod 502 is driven to rotate in the mounting plate 501, and then the connecting frame 2 is also driven by the mounting rod 502 to flip synchronously. When the positioning rod 504 moves to the specified position and is released, the spring 505 recovers its length to allow the positioning rod 504 to enter the limiting hole 506. At this time, the positions of the mounting rod 502 and the connecting frame 2 are also fixed.

[0027] like Figure 2 and Figure 4 As shown, a fixing component 6 is installed on the top of the connecting frame 2, and the fixing component 6 includes two limiting grooves 601 opened on one side of the top outer wall of the connecting frame 2, and a fixing plate 602 is slidably connected in the two limiting grooves 601, and a rack 603 is fixedly connected to the outer wall at one end of the two fixing plates 602 close to each other, and the two racks 603 are arranged opposite to each other, and a gear 604 is rotatably connected to the top outer wall of the connecting frame 2, and the two racks 603 are meshed with the gear 604, and a motor 605 is fixedly installed on the bottom outer wall of the connecting frame 2, and the rotating shaft of the motor 605 and the gear 604 are coaxially fixed.

[0028] The top outer walls of the two fixed plates 602 are each provided with an arc-shaped guide plate 4, and the two guide plates 4 are symmetrically arranged. When the workpiece is placed, it can be placed just between the two fixed plates 602 under the guidance of the two guide plates 4, making the workpiece placement process simpler.

[0029] The relative positions of the two fixed plates 602 are adjusted according to the model of the workpiece, so that the workpiece does not need to be clamped by hand and can be placed directly. By starting the motor 605 to drive the gear 604 to rotate, the gear 604 can drive the two fixed plates 602 to approach each other along the two limit grooves 601 through the two racks 603 engaged with it. Then, the workpiece is placed between the two fixed plates 602 to complete the positioning, and then the motor 605 drives the two fixed plates 602 to squeeze on both sides of the workpiece to complete the fixation.

[0030] like Figure 1 and Figure 2 As shown, a rubber sheet 7 is provided on the inner wall of one end of the two fixing plates 602 close to each other, which can increase the fixing effect and prevent the fixing plates 602 from damaging the workpiece, and the rubber sheet 7 and the inner wall of one end of the fixing plates 602 are kept at the same level, so that the rubber sheet 7 will not affect the normal placement of the workpiece.

[0032] like Figure 3 As shown, the outer edges of the plurality of limiting holes 506 are all provided with rounded corners, so that the process of inserting the positioning rod 504 into the limiting hole 506 is more convenient and has a higher fault tolerance rate.

[0033] The utility model provides a workpiece turning mechanism for a laser marking machine, and the specific working principle is as follows:

[0034] When the device is working, the relative position of the two fixing plates 602 is adjusted according to the model of the workpiece, so that the workpiece does not need to be clamped by hand and can be placed directly. By starting the motor 605 to drive the gear 604 to rotate, the gear 604 can drive the two fixing plates 602 to approach each other along the two limiting grooves 601 through the two racks 603 engaged with it. Then, the workpiece is placed between the two fixing plates 602 to complete the positioning, and then the motor 605 drives the two fixing plates 602 to squeeze on both sides of the workpiece to complete the fixation. If the workpiece needs to be turned over, To change the angle, it is only necessary to pull the positioning rod 504 outward to make it leave the limiting hole 506. At this time, the connecting plate 503 will not be restricted, and the spring 505 will also be forced to lengthen. Then, by toggling the connecting plate 503, the mounting rod 502 is driven to rotate in the mounting plate 501, and then the connecting frame 2 is also driven by the mounting rod 502 to flip synchronously. When the positioning rod 504 moves to the specified position and is released, the spring 505 restores its length to allow the positioning rod 504 to enter the limiting hole 506. At this time, the positions of the mounting rod 502 and the connecting frame 2 are also fixed.
