[0006] In the above or some embodiments, it also includes a paper pressing plate located above the drawer box, the paper pressing plate is installed above the drawer box by pivot rotation, and also includes a third drive motor transmission connected to the paper pressing plate. When the drawer box makes intermittent motion of a specified distance, the third drive motor is used to drive the paper pressing plate to press the sheet and the pasting substrate to prevent the sheet from moving during the movement of the drawer box.

[0007] In the above or some embodiments, a rotational connection relative to a pivot is formed at one edge of the paper pressing plate through a pivot, and a torsion arm spring is connected between the pivot and the paper pressing plate, forming a structure in which the paper pressing plate returns to an initial position under the action of the torsion arm spring, and the pivot is transmission-connected to the third drive motor.

[0008] In the above or some embodiments, the driving mechanism includes a tray located below the drawer, and the tray limits the position of the drawer in at least one horizontal direction, so that when the tray moves in a specified direction, the drawer moves synchronously, and the tray is driven by a power mechanism.

[0009] In the above or one embodiment, a gear rack motion pair is provided under the tray, and the power mechanism also includes a second drive motor, which drives the gear to realize intermittent movement of the tray fixedly connected to the rack by a specified distance. The second drive motor is a stepper motor and also includes an encoder and a drive control circuit connected to the electrical signal of the stepper motor.

[0015] The invention also discloses an automatic pasting method for documents, which is used to solve the problems of low automation and difficulty in implementation in the existing automatic pasting process of documents.

[0016] STP1: First, the bill or document to be pasted is placed in the storage box; when the device of this scheme is started, the paper picker located between the storage box and the conveying device takes out the sheet in the storage box and conveys it to the entrance of the conveying device;

[0017] STP2: The conveying device at least includes a detection unit for detecting that the sheet material reaches the entrance of the conveying device. When the sheet material reaches the designated position, the detection unit transmits the information to the controller through the communication unit, and the controller controls the conveying device to convey the sheet material. The triangular wheel is driven by the first driving motor to rotate and the structure of the glue box swinging is realized by the triangular wheel.

You only need to place the sheet at the beginning and take out the substrate after pasting at the exit. In addition, the implementation structure and control method of the above solution are relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The driving mechanism 300 is to realize the sequential pasting of the bills or notes, and defines that each bill or note is evenly connected to the pasting area of ​​the pasting substrate. After the previous bill or note is pasted, before the next bill or note arrives, the driving mechanism 300 drives the drawer 200 to drive the pasting substrate to the next position, and the next position corresponds to the gluing position of the bill or note to be reached. In order to meet the above process, the driving mechanism 300 is configured to drive the drawer 200 to make intermittent movements of a specified distance in a horizontal direction, and the specified distance matches the specified position of the sheet material pasted on the surface of the pasting substrate, so as to realize a structure in which multiple sheets of the sheet material are sequentially transported to the same pasting substrate and pasted.

In order to realize the adaptive supply of adhesive 505, the adhesive is stored in a container 506 with a base and swinging on the inner wall of the glue box 500. A spring in a compressed state is provided between the container base and the bottom of the glue box 500, so that the adhesive is always in contact with one side of the glue coating roller or roller shaft 102 to realize glue supply.

[0042] Usage process: During specific use, the paper picker located between the storage box and the conveying device takes out the sheet in the storage box and conveys it to the entrance of the conveying device; when the sheet reaches the specified position, the detection unit transmits it to the controller through the communication unit and the controller controls the conveying device to convey it. At the same time, the triangular wheel rotates under the drive of the first driving motor and relies on the triangular wheel to realize the swing of the glue box. When the sheet passes through the roller or roller shaft, the glue-coated roller or roller shaft can absorb or dip the adhesive in the glue box; the glue-coated sheet is directionally conveyed by the paper guide to one end of the pasting substrate in the drawing box. When the driving mechanism drives the drawing box to move a specified distance in a horizontal direction, the third driving motor drives the paper pressing plate to press the sheet and the pasting substrate to prevent the sheet from moving during the movement of the drawing box. When the displacement movement is completed, the third driving motor stops outputting power and the paper pressing plate recovers under the action of the spring.
