Description

Technical Field

[0001] The invention relates to the field of automatic office technology, and in particular to an automatic stamping and signing device for handing over project completion drawings. Background Art

[0002] The project completion drawing is a drawing drawn by the construction unit according to the actual construction situation when the construction project is completed. Because modifications are inevitable during the construction process, in order to allow customers (construction units or users) to have a clearer understanding of the actual direction of the pipeline and the actual installation of the equipment, the state stipulates that the construction unit must submit the project completion drawing after the project is completed.

[0003] At present, there are more and more State Grid UHV and other such projects that need to be completed and archived. The work is becoming more and more normalized, with special requirements and high repetition. For example, red file number stamps and completion drawing review stamps need to be stamped on each paper blueprint. The file number needs to be written on each file number stamp, and the name of the reviewer and the date need to be signed on the completion drawing review stamp. At the same time, the stamp position must be in the blank space in the upper right corner of the institute drawing frame. If there is no blank space, it is stamped in the blank space around the institute drawing frame. Words cannot be pressed, and the handwriting in the stamp should be clear and not blurred, and the stamp should be straight and not crooked. At present, the way to stamp and sign such paper blueprints is mostly through manual stamping and signing, but manual stamping and signing is time-consuming and labor-intensive, and is prone to errors, resulting in unclear stamps, pressed words, etc., causing later rework and waste of resources.

The rotating plate 505 can be moved under the action of an external force through the setting of the pin shaft 503. When the rotating plate 505 rotates around the pin shaft 503, and when the external force is lost, it returns to the original position under the action of the torsion spring 504. One end of the paper pressing shaft 506 is provided on the other end of the rotating plate 505. The other end of the paper pressing shaft 506 is horizontally extended in the direction close to the mounting plate 502 on the other side. A paper pressing wheel 507 is rotatably sleeved on the paper pressing shaft 506. The bottom of the paper pressing wheel 507 is in contact with the top surface of the paper board 500. The paper pressing assembly is used to roll the passing drawings to ensure that the paper surface is as flat as possible. The paper pressing roller 507 is arranged to prevent the inaccuracy of the subsequent stamping and signing operation caused by the wrinkles on the paper surface.

When the first conveying motor 511 starts to work, it can drive the first rotating shaft 512 to rotate, thereby driving the first conveying wheel 513 to rotate. The rotation of the first conveying wheel 513 can generate a thrust on the drawing under the action of friction, thereby conveying the drawing.

[0034] A stamping and signing mechanism 6 for stamping and signing drawings and a camera mechanism 7 for identifying image information of drawings are arranged in sequence from bottom to top at a position above the working platform 4 in the chassis 1. The stamping and signing mechanism 6 includes a stamping component 61 for stamping, a signing component 62 for signing, and a driving component for driving the stamping component 61 and the signing component 62 to move in the X-axis and Y-axis directions.

The power supply is electrically connected to the single-chip microcomputer control to provide the required working current for the paper feeding mechanism 5, the stamping and signing mechanism 6, the camera mechanism 7, the paper straightening mechanism 8 and the control panel 9.

[0040] The working platform 4 is provided with symmetrically arranged limit strips 11, and the distance between the limit strips 11 on both sides is adapted to the width of the drawings. The drawings delivered by the paper feeding mechanism 5 can just enter the limit strips 11 on both sides.

[0041] The working principle of the present invention is that when it is necessary to stamp and sign the engineering completion drawing, the user puts the drawing from the paper feeding port 2 onto the paper placing paper 500 in the paper feeding mechanism 5, and lifts the paper pressing shaft 506 and the paper pressing wheel 507 upward by pulling the rotating plate 505, and then places the end of the drawing close to the paper feeding port 2 under the paper pressing wheel 507, and then releases the rotating plate 505. The rotating plate 505 performs a reset movement under the action of the torsion spring 504, so that the paper pressing wheel 507 presses the drawing tightly, and the ultrasonic thickness detection sensor 501 on the paper placing paper 500 detects the thickness of the drawing and sends a signal to the single-chip controller. After receiving the electrical signal, the single-chip controller generates an action signal to control the first conveying motor 511 to start working, and convey the drawings on the paperboard 500. When the drawings on the paperboard 500 enter the working platform 4, the single-chip controller controls the camera mechanism 7 to obtain the image information of the drawings and send it to the single-chip controller. The single-chip controller distinguishes the coordinates of the text area and the blank area of ​​the drawing image information by identifying the drawing image information. Then, the single-chip controller controls the driving component to transport the stamping component 61 and the signature component 62 to the coordinates of the blank area, that is, by controlling the first motor 604 The second motor 610 starts working, and the stamping component 61 and the signature component 62 move along the first slide bar 601 and the second slide bar 603 along the X-axis and the Y-axis, so as to transport the stamping component 61 and the signature component 62 to the coordinates of the blank area, and then control the stamping component 61 and the signature component 62 to start working to stamp and sign the drawings. When stamping, the third motor 6103 can stamp the drawings by moving the seal 6108 downward, and when signing, the fourth motor 6203 moves the signature pen 6210 downward to contact the drawings, and the single-chip controller needs to control The driving component drives the signature component 62 to move along the X-axis and the Y-axis to sign the corresponding name. After the stamping and signing work is completed, the single-chip controller controls the driving component to reset the stamping component 61 and the signature component 62, and then controls the paper feeding component to start working, and sends the drawings on the working platform 4 from the paper outlet 3 to the paper receiving box 81 of the paper straightening mechanism 8. After that, the single-chip controller controls the vibration control box 82 to control the vibration plate in the paper receiving box 81 to vibrate, thereby vibrating the drawings in the paper receiving box 81, so that the drawings are attached to the inner wall of one side of the paper receiving box 81, thereby completing the work of collecting the drawings.

[0042] At the same time, since the stamping and signing work has a certain degree of confidentiality, a fingerprint verification module can be added to the device. The device can only be started after fingerprint verification, thereby enhancing confidentiality.
