When the object to be printed S1 is a sole cloth of a shoe, it includes the object to be printed S1 of the left foot and the object to be printed S1 of the right foot, and since the image recognition module 2300 has captured the image of the object to be printed S1, the control module 2910 can know that the object to be printed S1 printed at present is the object to be printed S1 of the left foot or the object to be printed S1 of the right foot, so that the left foot or the right foot automatic receiving module 2800 can automatically divide the object to be printed S1 into the corresponding left foot area or the right foot area, thereby reducing the labor and time for subsequent distribution.

Referring to fig. 6 and fig. 1 to 5 together, fig. 6 is a block flow diagram illustrating an automatic printing method 3000 according to embodiment 3 of the present invention, in which the automatic printing method 3000 is used for printing on a plurality of objects to be printed S1 and includes a conveying step S02, a position recognizing step S03 and a printing step S04. Details of the automatic printing method 3000 will be described below in conjunction with the

automatic printing machines

1000, 2000.

In the transporting step S02, the transporting

belts

1200 and 2200 are provided to automatically transport the plurality of objects to be printed S1.

In the position recognition step S03, the

image recognition module

1300,2300 captures at least one image including the to-be-printed object S1 and at least one recognition pattern P1, and the control module 2910 analyzes the at least one image to provide the to-be-printed object S1 with a printing position corresponding to the at least one recognition pattern P1.

In the printing step S04, the

printing modules

1400 and 2400 receive the printing position of the to-be-printed object S1, so as to print a predetermined pattern on the to-be-printed object S1.

Specifically, in the transporting step S02, the transporting

belts

1200,2200 are continuously operated in a loop, so that the object to be printed S1 placed on the transporting

belts

1200,2200 is transported to the lower side of the

image recognition modules

1300,2300 and then transported to the lower side of the

printing modules

1400,2400, so as to continuously and sequentially transport the object to be printed S1. When the

conveyor

1200,2200 conveys the object to be printed S1 to the lower part of the

image recognition module

1300,2300, the

image recognition module

1300,2300 can shoot at least one image of the object to be printed S1 and at least one recognition pattern P1, and since the recognition pattern P1 can have the dot marks P14, P15, P16, P17, two straight lines P18, P19, and the like, by analyzing the distances, angles, and the like between the object to be printed S1 and the dot marks P14, P15, P16, P17, two straight lines P18, P19, the relative position of the object to be printed S1 can be calculated, and the printing position can be determined. Thus, when the

conveyor belts

1200,2200 continuously and continuously convey a plurality of objects to be printed S1, the printing position dedicated to each object to be printed S1 can be determined, and printing can be accurately performed.

As shown in fig. 1 to 4 and 6, the at least one identification pattern P1 can be displayed on the conveying surface 1201 of the conveyor 1200 and moves with the conveyor 1200, and in the printing step S04, the printing module 1400 reads and determines that the start mark P11 of the at least one identification pattern P1 is a print head. In this way, the print module 1400 can start printing by determining the print head. However, in other embodiments, when the image recognition module captures a plurality of images, the control module can also determine the moving speed of the object to be printed according to the plurality of images, estimate the time when the object enters the lower portion of the printing module, and notify the printing module to start printing, but the present invention is not limited thereto.

As shown in fig. 5 and 6, the automatic printing method 3000 may further include a feeding step S01, in which the feeding module 2930 provides feeding information to the control module 2910, and the feeding sensor 2920 senses whether the to-be-printed object S1 enters the conveyor 2200, and in the feeding step S01, if the control module 2910 receives the feeding information but the feeding sensor 2920 does not sense that the to-be-printed object S1 has entered the conveyor 2200, the control module 2910 may issue an alarm message. Since the feeding module 2930 is an automatic feeding module, in order to avoid abnormal feeding, the feeding sensor 2920 may be used to determine whether the object to be printed S1 has entered the conveyor 2200, and then an alarm sound may be given through the alarm information, so as to achieve the warning effect.

In addition, the automatic printing method 3000 may further include a detection step S05, an abnormal product removing step S06, and a left/right automatic receiving step S07. In the detecting step S05, the finished image detecting module 2600 may be used to check the object to be printed S1 to determine whether the predetermined pattern is complete and the position is correct; in the abnormal product exclusion step S06, the abnormal product exclusion module 2700 may exclude the abnormal product. Finally, in the step S07, the left or right automatic receiving module 2800 automatically separates the object to be printed S1 into corresponding left or right foot areas. It should be noted that, in other embodiments, the left and right automatic receiving steps may be any receiving steps, which can automatically classify and receive the objects to be printed, and are not limited to only distinguish the left or right foot.

Although the present invention has been described with reference to the above embodiments, it is to be understood that the invention is not limited thereto, and that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.
