In this embodiment, the information obtaining component is configured to obtain information of a target device that needs to be attached to a tag currently, and when the tag is attached, the target device is placed in a tray on the conveyor belt, where a stop block is disposed at an upper left corner and a lower left corner of the tray, and is used for fixing the target device; after the transmission belt transmits the target equipment to the lower part of a first bracket of the information acquisition assembly, an image acquisition device arranged at the top of the first bracket acquires an image of the target equipment, and a bar code scanning device arranged on the side wall of the first bracket scans equipment running water codes on the target equipment, so that project information and material information of the target equipment are obtained; after the controller acquires the target equipment image, the item information and the material information, carrying out edge recognition on the target equipment image to obtain the edge position information of the target equipment, and determining the label arrangement information corresponding to the target equipment according to the item information and the material information.

Specifically, the gradient operator may include a Sobel (Sobel) operator, a Roberts (Roberts) operator, a laplace (Laplacian) operator, and the like, and the larger the gradient value of a pixel is, the larger the change of the pixel in the gradient direction is, the more likely the pixel is an edge point, and therefore, the edge position information of the face where the label attaching position of the target device is located can be determined according to the gradient value. For example, if the target device is a notebook and the label attachment position is on the C-face of the notebook (i.e. the face of the keyboard of the notebook), the edge position information represents the position information of four boundaries of the C-face of the notebook.
Step S103, acquiring item information and material information of the target equipment based on a bar code scanning device in the information acquisition component.

In this embodiment, after the edge position information and the label arrangement information of the target device are obtained, the label attaching position on the target device may be determined based on the edge position information, for example, if the target device is a notebook, and the distance between the left boundary of the label attaching position of the notebook and the left boundary of the C-plane of the notebook is 2 cm, and the distance between the lower boundary of the label attaching position of the notebook and the lower boundary of the C-plane of the notebook is 3 cm, the label attaching position of the target device may be determined according to the edge position information of the target device, and the label projection component may be controlled to project the label arrangement information to the label attaching position, and the staff may attach the label actually corresponding to the target device according to the projected label arrangement information.

Specifically, the label arrangement template is the most complete label template corresponding to the machine type of the target equipment, namely all labels corresponding to the machine type are arranged in advance, so that the label arrangement template is generated, for example, the label arrangement template can comprise four labels, the four labels are integrally arranged in a 'field' shape, and the arrangement position of each label is fixed; the labels corresponding to the target device do not necessarily include all the labels corresponding to the machine type to which the labels belong, for example, if the label arrangement template includes four labels, the labels corresponding to the target device may only include three of the four labels in the label arrangement template.
Step S203, determining label arrangement information corresponding to the target equipment according to the label arrangement template and the labels.
In this embodiment, a first position of a tag corresponding to a target device in a tag arrangement template may be determined first, and if the first position meets a preset condition, the tag corresponding to the target device is moved from the first position to a second position according to a preset arrangement rule, so as to obtain tag arrangement information corresponding to the target device. The first position meets the preset condition, namely the labels on the left side or below the first position are missing; the preset arrangement rule is left shift when meeting a defect or downward shift when meeting a defect.
Specifically, the following exemplifies a specific procedure of step S203:
if the label arrangement template comprises four labels, the four labels are integrally arranged in a 'field' shape, the arrangement position of each label is fixed, the position of each label corresponding to the target equipment is three, the position of each label in the label arrangement template is determined, for example, the first label A is positioned at the left upper corner of the label arrangement template, the second label B is positioned at the left lower corner of the label arrangement template, the third label C is positioned at the right upper corner of the label arrangement template, wherein the third label C is positioned at the right upper corner of the label arrangement template, the labels below the first position of the third label C are missing, therefore, the first position of the third label C meets the preset condition, and then the third label C can be moved from the right upper corner of the label arrangement template to the right lower corner of the label arrangement template according to the preset arrangement rule, so that the label arrangement information corresponding to the target equipment is obtained. Fig. 4 shows a schematic view of a label positioning method according to a third embodiment of the present disclosure, wherein fig. 4a shows a schematic view of a first label positioning method according to a third embodiment of the present disclosure; fig. 4b shows a second schematic view of a label positioning method according to a third embodiment of the disclosure; fig. 4c illustrates a third schematic view of a scenario of a tag locating method according to a third embodiment of the present disclosure, where tag arrangement information corresponding to a target device may be as shown in fig. 4a, fig. 4b, and fig. 4 c. It should be emphasized that the tag arrangement information corresponding to the target device may also be other manners, for example, the tag arrangement information may also include four tags, that is, the tag arrangement information is the same as the tag arrangement template, and other cases.

Specifically, the projection distance may be stored in item information to the target device, and the projection distance may be determined based on the item information.

In this embodiment, the tag projection assembly further includes a bracket and a sensing device, where the projecting device and the sensing device are disposed at the top of the bracket, and step S302 may specifically include: measuring the real distance between the projection device and the target equipment according to the sensing device; and if the real distance is not equal to the projection distance, adjusting the height of the bracket from the real distance to the projection distance. Specifically, the height of the support is adjustable, the sensing device such as a distance sensor can measure the vertical real distance between the projection device and the surface where the target device label is attached, and when the real distance is unequal to the projection distance, the height of the support is adjusted from the real distance to the projection distance.
In step S303, the projecting device is controlled to project the label arrangement information to the label attaching position of the target device according to the edge position information under the projection distance.
