Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 The present invention provides an automatic marking machine for a retainer, which is characterized by comprising:

[0026] A frame 1 is provided with a conveyor belt 101 and a guide rail 2, the guide rail 2 is provided above the conveyor belt 101, a first positioning portion 201 is provided on the guide rail 2, and the width of the guide rail 2 corresponds to the width of the workpiece;

[0027] A detection device 3 is provided on the frame 1, and the position of the detection device 3 corresponds to the position of the first positioning portion 201;

[0028] The laser marking device 4 includes a laser head 401 , the position of the laser head 401 corresponds to the first positioning portion 201 ;

[0029] The positioning device 5 is arranged on the frame 1, and the positioning device 5 includes a driving device 501 and a positioning member 502. The driving device 501 is transmission-connected to the positioning member 502. The position of the positioning member 502 is arranged opposite to the first positioning portion 201. The end of the positioning member 502 is provided with a second positioning portion 503. The second positioning portion 503 and the first positioning portion 201 are arranged opposite to each other. The driving device 501 can drive the positioning member 502 to move to the first position and the second position. When the positioning member 502 is in the first position, the positioning member 502 is located on the outside of the guide rail 2. When the positioning member 502 is in the second position, the second positioning portion 503 is located directly above the guide rail 2, and the distance between the second positioning portion 503 and the first positioning portion 201 is greater than half the width of the guide rail 2.

[0030] The embodiment of the present utility model provides an automatic marking machine for a holder, characterized in that it includes: a frame 1, a detection device 3, a laser marking device 4 and a positioning device 5. During detection, the conveyor belt 101 will drive the holder to enter the guide rail 2. The holder is generally cylindrical with a protruding middle part. The width of the guide rail 2 is slightly larger than the diameter of the holder, which can limit the moving direction of the holder and make the movement process of the holder on the guide rail 2 smoother. The detection device 3 and the positioning device 5 are sequentially arranged along the moving direction of the holder. The detection device 3 is used to detect the position of the holder. When the detection device 3 detects that the holder is close to the first positioning part 201, the driving device 501 drives the positioning member 502 from the first position to the second position. The distance between the second positioning part 503 and the first positioning part 201 is greater than half the width of the guide rail 2. Since the width of the guide rail 2 is slightly larger than the diameter of the holder, it is ensured that the second positioning part 503 is aligned with the first positioning part The distance between the second positioning portion 503 and the first positioning portion 201 is greater than the radius of the retaining frame, and the distance between the second positioning portion 503 and the first positioning portion 201 is less than the diameter of the retaining frame, and the second positioning portion 503 is located directly above the guide rail 2. When the retaining frame contacts the second positioning portion 503 of the positioning member 502, it continues to move under the drive of the conveyor belt 101. Since the outer side surface of the retaining frame is a circular arc surface, it will deflect and move in the direction away from the positioning member 502, thereby approaching the first positioning portion 201 and finally making the outer side of the retaining frame fit the first positioning portion 201. The first positioning portion 201 and the second positioning portion 503 cooperate to limit the position of the retaining frame; after positioning, the laser marking device 4 engraves a code on the retaining frame; the automatic marking machine utilizes the characteristics of the shape of the retaining frame itself, and can complete the positioning of the retaining frame by setting the guide rail 2 and the positioning member 502.

During operation, the retaining frame is restricted from moving between the first guide rod 202 and the second guide rod 203, thereby limiting the moving direction of the retaining frame. The first guide rod 202 is provided with a first positioning portion 201. During positioning, when the retaining frame contacts the second positioning portion 503 of the positioning member 502, it continues to move under the drive of the conveyor belt 101. Since the outer side surface of the retaining frame is an arc surface, it will deflect and move in the direction away from the positioning member 502, thereby approaching the first guide rod 202 and fitting with the first guide rod 202. Through the cooperation of the positioning member 502 and the first guide rod 202, a positioning effect can be achieved.
