[0014] Please refer to Figure 1A printed mark detection device comprises a detection machine 1, a scanning head 2 and a transfer mechanism 3, wherein the detection machine 1 is provided with a scanning head 2 movable along the length direction of the detection machine 1; the transfer mechanism 3 comprises a moving frame 31, a plurality of adsorption arms 32, a first moving device and a second moving device, wherein the moving frame 31 is arranged above the detection machine 1, and the moving frame 31 comprises a vertical support 312 perpendicular to the length direction of the detection machine 1 and a horizontal support 311 parallel to the length direction of the detection machine 1; the horizontal support 311 is connected to the first moving device and is movable along the length direction of the vertical support 312; a plurality of adsorption arms 32 are provided on the horizontal support 311, and the adsorption arms 32 are connected to the second moving device and are movable along the length direction of the horizontal support 311; the adsorption arms 32 comprise a telescopic arm 321 movable along the height direction of the detection machine 1, an adsorption head 322 and a first distance sensor 323, the telescopic arm 321 is connected to the adsorption head 322, and the adsorption head 322 is provided with a first distance sensor 323.

[0015] From the above description, it can be seen that the beneficial effects of the utility model are: by utilizing the cooperation between the adsorption arm 32 and the movable frame 31, the adsorption arm 32 can be quickly moved in the horizontal and vertical directions of the table surface of the detection machine 1; the telescopic arm 321 of the adsorption arm 32 and the adsorption head 322 can cooperate to quickly adsorb and transfer the carton on the material cart; through the movement setting of multiple adsorption arms 32 and the arrangement of the first distance sensor 323, it is possible to pre-move the adsorption arm 32, judge the size of the carton based on the feedback of the first distance sensor 323 on the adsorption arm 32, and then determine the required number of adsorption arms 32 and the adsorption position, to ensure that the force on the carton is uniform during adsorption.

[0016] Furthermore, a loading induction plate 11 is provided at one end of the detection machine 1 corresponding to the vertical bracket 312 , and a second distance sensor 12 is provided on the loading induction plate 11 .

[0017] It can be known from the above description that the second distance sensor 12 of the loading sensing plate 11 senses the cartons on the material cart to control the movement of the adsorption arm 32 for adsorption transfer.

[0018] Furthermore, the detection machine 1 is provided with a fixing device 4, and the fixing device 4 includes a first push plate 41, a first pushing device, a second push plate 42 and a second pushing device.
