The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0052] In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like, orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.

[0053] The present embodiment proposes a rotary disc type two-dimensional code laser engraving device for laser engraving and converting two-dimensional codes according to the incoming two-dimensional codes of products, and binding the converted two-dimensional codes with information labels of the products, so as to improve the production efficiency of the products, and also to avoid the phenomenon that the product information does not match the converted two-dimensional code in the binding process.

[0054] Specifically, please refer to Figure 1 and Figure 2 , the rotary disc type two-dimensional code laser engraving device comprises a rotary disc 1, a first code scanner 2, a laser engraving mechanism 3, a second code scanner 4, a shooting mechanism 5, a feeding and discharging mechanism 6, and a binding module. The rotary disc 1 can rotate around its own axis, and a plurality of positioning jigs 11 for fixing products 100 are arranged on the rotary disc 1, and any positioning jig 11 periodically passes through a feeding and discharging station, a laser engraving station, a detection station, and a binding station in turn. The first code scanner 2 is opposite to the product 100 at the laser engraving station and is used to scan the incoming two-dimensional code of the product 100. The laser engraving mechanism 3 is arranged at the laser engraving station and is electrically connected with the first code scanner 2. The laser engraving mechanism 3 is used to laser engrave and convert two-dimensional codes 120 for the product 100 at the laser engraving station. The second code scanner 4 is arranged at the detection station. The second code scanner 4 is electrically connected with the binding module, and is opposite to the product 100 at the detection station to scan the converted two-dimensional code 120 of the product 100. The shooting mechanism 5 is arranged at the binding station. The shooting mechanism 5 is opposite to the product 100 at the binding station and is used to shoot the image of the information label 110. The shooting mechanism 5 is electrically connected with the binding module. The feeding and discharging mechanism 6 is arranged at the feeding and discharging station. The feeding and discharging mechanism 6 is used to take down the product 100 fixed in the positioning jig 11 at the feeding and discharging station, and place another product 100 in the positioning jig 11. The binding module can bind the information label 110 of the product 100 with the converted two-dimensional code 120.

[0055] It can be understood that the product 100 is placed on the positioning fixture 11 at the loading and unloading station through the loading and unloading mechanism 6. As the turntable 1 rotates, the product 100 passes through the laser engraving station, the inspection station and the binding station in sequence. Correspondingly, the next positioning fixture 11 will be transferred to the loading and unloading station, and the loading of the next product 100 can be completed under the action of the loading and unloading mechanism 6. Such an arrangement can ensure the continuity of batch products 100 during laser engraving, thereby improving production efficiency. When the product 100 is transferred to the laser engraving station, the first barcode scanner 2 can identify the incoming QR code, so that the laser engraving mechanism 3 can laser engrave the transcoded QR code 120 according to the incoming QR code, thereby avoiding the mismatch between the transcoded QR code 120 and the incoming QR code; the second barcode scanner 4 can scan the transcoded QR code 120 to facilitate the identification of the transcoded QR code 120. If the transcoded QR code 120 is unqualified, the unqualified information is fed back to the shooting mechanism 5. After the product 100 is transferred to the binding station, there is no need to bind the transcoded QR code 120 with the information label 110. If the transcoded QR code 120 is qualified, the qualified information is fed back to the shooting mechanism 5. After the product 100 is transferred to the binding station, the shooting mechanism 5 can identify the information label 110 and bind the information label 110 with the transcoded QR code 120. With this arrangement, the transcoded QR code 120 can be directly bound to the information label 110 after laser engraving. Compared with manual binding, the inconsistency between the transcoded QR code 120 and the information label 110 can be avoided during the binding process.

[0056] Preferably, a four-station divider is provided at the rotating bottom, which can drive the turntable 1 to move indirectly, so that each positioning fixture 11 can be accurately transferred to the laser engraving station, the inspection station or the binding station to avoid secondary positioning of the product 100 at any station, thereby further improving production efficiency.

[0057] See also Figure 3 In this embodiment, a plurality of in-position sensors 7 are evenly distributed around the circumference of the turntable 1, and the number of the plurality of in-position sensors 7 is consistent with the number of the positioning jigs 11. It can be understood that the in-position sensors 7 include a magnetic sheet and a detection element. The magnetic sheet is fixedly set on the turntable 1, and the detection element is set around the circumference of the turntable 1. During each rotation of the turntable 1, if the plurality of magnetic sheets can be respectively set in a one-to-one correspondence with the plurality of detection elements, a signal indicating that the turntable 1 has been rotated into position can be issued. If there is a deviation between the positions of the magnetic sheets and the detection elements, a signal indicating that the turntable 1 has not been rotated into position can be issued. In this way, the staff will check the position of the product 100 and make corrections. Such a setting can further ensure the movement accuracy of the positioning jig 11.

[0058] In addition, the turntable-type QR code laser engraving equipment also includes a product 100 sensor 8, which is installed at the loading and unloading station and is used to detect whether the positioning fixture 11 at the loading and unloading station is fixed with a product 100. The product 100 sensor 8 is electrically connected to the turntable 1. It can be understood that the product 100 can detect the product 100 placed on the positioning fixture 11 for loading and unloading. If the positioning fixture 11 detects that the product 100 is fixed, a rotation signal is sent to the turntable 1. If the positioning fixture 11 does not detect that the product 100 is fixed, an alarm is issued to facilitate the staff to conduct a second inspection.

[0059] Please refer to Figure 4. In this embodiment, the loading and unloading mechanism 6 includes a first loading tray 611, a second loading tray 612, a first driving part 613 and a manipulator 62. The first loading tray 611 is used to carry unprocessed products 100; the second loading tray 612 is used to receive processed products 100, and the second loading tray 612 is arranged in parallel with the first loading tray 611; the driving end of the first driving part 613 is connected to the first loading tray 611 and the second loading tray 612 at the same time to simultaneously drive the first loading tray 611 and the second loading tray 612 toward or away from the loading and unloading station; the manipulator 62 is arranged at the loading and unloading station, and the moving end of the manipulator 62 is provided with two grippers 621, and the two grippers 621 are respectively opposite to the first loading tray 611 and the second loading tray 612. It can be understood that the two grippers 621 are named the first gripper 621 and the second gripper 621 respectively. During the loading process, the first gripper 621 can grab the product 100 on the first carrier 611, and under the action of the manipulator 62, the product 100 can be transferred to the top of the positioning fixture 11 at the loading and unloading station. At this time, the second gripper 621 can grab the product 100 on the positioning fixture 11 to complete the unloading. Then, the first gripper 621 can place the product 100 on the positioning fixture 11. Then, the turntable 1 starts to rotate, and the manipulator 62 places the unloaded product 100 on the second carrier 612. During the placement process, the first gripper 621 can grab the next product 100 at the same time. Such a setting can ensure the continuity of loading and unloading of the product 100, thereby further improving production efficiency. Among them, the first driving part 613 is preferably a cylinder slide. Of course, in some other feasible embodiments, the first driving part 613 can also be other existing driving structures, which will not be elaborated here.

[0060] Furthermore, a first loading tray 611, a second loading tray 612, and a first driving unit 613 constitute a set of loading and unloading components 61. At least two sets of loading and unloading components 61 are provided. It is understood that while one set of loading and unloading components 61 is loading and unloading, the other set of loading and unloading components 61 can be moved away from the loading and unloading station to receive incoming materials from the previous process. This reciprocating process can further improve the efficiency of incoming materials.

[0061] See also Figure 5 In this embodiment, the photographing mechanism 5 includes a camera 511 and a light source 512. The camera 511 is aligned with the information label 110 to photograph the information label 110. The camera 511 is also electrically connected to the binding module to bind the identified information label 110 to the corresponding transcoded QR code 120. The light source 512 is provided on the camera 511 and is used to illuminate the product 100. It is understood that after the product 100 is transferred to the binding station, the camera 511 can photograph the information label 110 of the product 100 to identify the information label 110 of the product 100. If the information label 110 is correct, the information label 110 is bound to the corresponding transcoded QR code 120. If the information label 110 is incorrect, the binding is not performed and the blanking is subsequently completed. Compared to manual binding, this can avoid the phenomenon of mismatch between the transcoded QR code 120 and the information label 110 during the binding process.

[0062] Furthermore, multiple information labels 110 are provided; a camera 511 and a light source 512 form a binding component 51, and multiple binding components 51 are provided. The multiple binding components 51 correspond one-to-one with multiple information labels 110. It is understood that if a product 100 has multiple information labels 110, different cameras 511 are required to identify them, thereby ensuring the accuracy of the recognition of each information label 110 and ensuring that all information labels 110 of the product 100 are bound to the transcoded information.

[0063] In particular, the photographing mechanism 5 further includes a vertical rod 52, a horizontal rod 53, and a fixing base 54. The horizontal rod 53 is provided on the vertical rod 52, and the height position of the horizontal rod 53 is adjustable. The fixing base 54 is rotatably provided on the horizontal rod 53, and the camera 511 is provided on the fixing base 54. It is understood that by adjusting the height of the horizontal rod 53, the height of the camera 511 can be adjusted, and when the fixing base 54 is rotated, the angle of the camera 511 can be adjusted to ensure that the camera 511 can recognize information labels 110 in different positions, thereby improving the applicability of the turntable-type QR code laser engraving device.

[0064] In this embodiment, the laser engraving mechanism 3 includes a laser engraving machine 31 and a fan 32. The laser engraving machine 31 is directly opposite the position of the product 100 to be laser engraved and is used to laser engrave the transcoded QR code 120. The fan 32 includes an air inlet and an air outlet. The air inlet is directly opposite the product 100, and the air outlet is facing away from the product 100. It can be understood that the debris generated during the laser engraving process can be absorbed by the fan 32. That is, during the laser engraving process, the debris enters the fan 32 through the air inlet and is discharged through the air outlet. This configuration can ensure the cleanliness of the surface of the product 100, thereby facilitating scanning by the second barcode scanner 4.

[0065] In the embodiment, the rotary disc type two-dimensional code laser etching device further comprises a third carrier disc 9 and a second driving part 10, the third carrier disc 9 is used for carrying unqualified products 100 and is arranged at the driving end of the second driving part 10, and the second driving part 10 is used for driving the third carrier disc 9 to move towards or away from the feeding and discharging station. It can be understood that the products 100 with failed two-dimensional code scanning, the products 100 with failed laser etching and the products 100 with unclear information labels 110 can be transferred to the feeding and discharging station again after the rotary disc 1 rotates, and can be discharged under the action of the manipulator 62. In order to distinguish the unqualified products 100 from the qualified products 100, the manipulator 62 places the unqualified products 100 on the third carrier disc 9, and after a certain number of unqualified products 100 are collected in the third carrier disc 9, the third carrier disc 9 is moved out of the feeding and discharging station under the action of the second driving part 10. The second driving part 10 is preferably a cylinder sliding table, and of course in some other feasible embodiments, the second driving part 10 can also be other existing driving structures, which will not be described here.

[0066] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not the limitation of the embodiments of the utility model. For ordinary skilled in the art, various obvious changes, re-adjustment and replacement can be made without departing from the protection scope of the utility model. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
