Description

Technical Field

[0001] This utility model relates to the field of paper processing equipment technology, specifically an intelligent vision positioning exercise book cutting machine. Background Technology

[0002] Exercise book cutting is a core step in post-printing processing, requiring high-precision edge trimming, efficient stacking of multiple books, and smooth cut edges. Traditional equipment generally suffers from the following bottlenecks: Stacking relies on manual labor: manual placement and alignment are required, which is inefficient and has a misalignment rate of >1.5mm; Unstable cutting quality: When cutting multiple books, the paper sticks together, resulting in a rough edge rate of >12%, requiring secondary processing; Insufficient flexibility: Changing book size requires adjusting the mechanical structure, which takes ≥15 minutes; The patent with patent number CN202322916512.X proposes "a fully automatic multi-functional cutting machine" that requires manual cranking of gears to drive the extrusion plate, and lacks thickness adaptive design, resulting in a large amount of misalignment. Utility Model Content

The visual positioning system includes a top industrial camera and a side industrial camera; the top industrial camera is located directly above the cutting station; the side industrial camera is located to the left of the stack conveying direction, with its optical axis forming a 90° angle with the conveying direction.

[0005] As a preferred technical solution of this utility model, the initial height of the liftable stop is 2-5mm higher than the bottom surface of the stack of books, and after the pushing action is completed, it is lowered to below the bottom surface of the stack of books.

[0006] As a preferred technical solution of this utility model, the pushing direction of the left and right push rods is perpendicular to the running direction of the bottom conveyor belt, and the ends of the push rods are covered with a polyurethane buffer layer.

[0012] like Figure 1 As shown, this utility model proposes an intelligent vision positioning workbook cutting machine, including a conveyor belt, a lifting stacking platform, a three-way alignment mechanism, an ultrasonic anti-sticking module, a cutting unit, and a vision positioning module; the conveyor belt is located at the entrance of the equipment, the lifting stacking platform is located at the end of the conveyor belt, and the platform surface is provided with negative pressure adsorption holes; The three-way alignment mechanism includes left and right push rods, a liftable stop post, and a bottom conveyor belt; the left and right push rods are symmetrically distributed on both sides of the book stack; the liftable stop post is vertically set at the front end of the book stack in the forward direction; the bottom conveyor belt is horizontally located below the alignment station. The ultrasonic anti-adhesion module is located on the cutting entrance side; the cutting unit includes left and right side blades and a cross blade. The visual positioning system includes a top industrial camera and a side industrial camera; the top industrial camera is located directly above the cutting station; the side industrial camera is located to the left of the stack conveying direction, with its optical axis forming a 90° angle with the conveying direction.

[0013] The initial height of the liftable stop is 2-5mm higher than the bottom surface of the stack of books, and it lowers to below the bottom surface of the stack of books after the pushing action is completed.

[0014] The pushing direction of the left and right push rods is perpendicular to the running direction of the bottom conveyor belt, and the ends of the push rods are covered with a polyurethane buffer layer.

[0015] The left and right side blades move in a direction parallel to the book's cut, the horizontal blade moves in a direction perpendicular to the top and bottom edges of the book, and the interval between the three blade movements is ≤0.1s.

[0016] The steps of the three-way alignment mechanism are as follows: The stop column rises, the rear push rod pushes the stack of books, and the left and right push rods close synchronously toward the center of the stack of books. The stop column descends to the bottom of the stack of books, and the bottom conveyor belt starts to transport the stack of books.

[0017] Working principle: The exercise books are fed individually onto an anti-slip conveyor belt with adjustable tilt angles. The conveyor belt surface has silicone stripes to prevent slippage. Once the books reach the lifting stacking platform, the platform's negative pressure suction instantly activates and secures them. For each book received, the servo-driven platform precisely lowers by the thickness of one book. After a certain number are stacked, the rear electric push rods move the stack forward at a low speed of 0.05 m / s. Once the stack enters the alignment position, the pneumatic push rods on both sides simultaneously close towards the center, applying a constant 30 N lateral pressure to compact the books. At the same time, two adjustable baffles at the front (2 mm higher than the thickness of a single book) block the forward movement of the stack, ensuring... After the front edges are aligned and pushed together, the stop column automatically descends below the bottom of the book, and the bottom variable frequency conveyor belt starts to carry the stack of books into the cutting area. An industrial camera scans the stack of books from the top and sides to generate a point cloud model of the actual size. After comparing the actual size with the design size, the system dynamically calculates the cutting path compensation value. The left and right side blades move synchronously along the X-axis to cut the left and right sides of the stack of books in one go. After the side blades retract, the horizontal blade presses down along the Y-axis to cut the top and bottom edges. At the same time as cutting, ultrasonic vibration (frequency 28kHz) is started to separate the paper fibers through high-frequency micro-vibration. After cutting, the conveyor belt removes the finished stack of books. No manual intervention is required throughout the process. Detailed Implementation Example 1

[0018] Taking cutting 20 B5 exercise books, each 8mm thick, as an example: Stacking stage: The inclined conveyor belt transports books to the lifting platform at 0.8m / s. The platform descends by 8mm for each book received, and the total descent is 160mm after stacking 20 books. Alignment stage: The rear push rod pushes the stack of books at 0.05m / s, the stop column rises to the 10mm height limit, and the pneumatic push rods on both sides close and compact with 30N pressure, with the book misalignment ≤0.2mm; Cutting stage: The vision system scans and generates a compensation path, the left and right side blades cut the cuts simultaneously, the horizontal blade moves down to cut the top and bottom edges, and the ultrasonic module is activated to prevent sticking at the same time; Results: Total time: 25 seconds; cut surface finish: Ra=1.2μm; burr rate: 0.7%; finished product qualification rate: 100%.
