How to solve the pain points of the fitting accuracy of the automatic rigid box making machine

The structure of the rigid caver boxes is simple, and the proportion of modularization is large. In actual production, it is easy to form standardization to realize automatic production and reduce costs. Compared with the more complicated folding boxes and book-shaped boxes, it has incomparable advantages.

In the production of rigid boxes, the paper will be made into the same size and same shape by die-cutting, laminating, and other processing; the gray paper will also be cut into the same size and shape by die-cutting slotting and cornering. This series of processes can be fully automated.

If you want to achieve high-speed and accurate production, positioning and bonding is a crucial step. The use of visual dynamic tracking robots for automatic positioning and laminating operations can solve laminating accuracy in a manual process. The laminating speed is faster, and the repeatability is better.

A visual positioning and tracking system for heaven and earth cover is composed of the following hardware:

1. Robot (SCARA)

2. Conveyor belt

3. Visual positioning system

4. Encoder (to detect the position and speed of the conveyor belt)

The tissue paper is glued and transferred to the belt by the automatic feeder mechanism, and the belt moves through the photoelectric sensor and stops at the camera position. The robot will grab the paper shell at the reclaiming place after receiving the reclaiming permission signal. After receiving the photo signal, the host computer triggers the camera to take a photo to identify the edge of the paper, calculate the offset angle and coordinates, and send them to the robot. The robot completes the appropriate action according to the received offset coordinates.

You can watch the whole fitting processing. Early paper feeding, gluing, and later box grabbing and molding steps are all mature technologies. If you want to achieve high speed and high precision, visual positioning is the key.

In this regard, we invent a high-precision visual positioning system for rigid box manufacturing, which can meet customer requirements of imported or domestic robots, significantly improving the rigid box positioning accuracy and production efficiency and earth cover automatic lamination. In addition, the system is easy to operate. In the human-computer interaction interface, the user can quickly switch the visual template and fine-tune the position compensation value. It can realize the manipulator trajectory teaching, path planning, communication test, and direct visual control without third-party manipulator software. The robot runs.

Case:

Identify the position and angle of the paper on the conveyor belt, and calculate the offset from the reference coordinate. It sent the offset to the manipulator, and the manipulator grabs the paper shell to complete the bonding according to the offset.

System Components:

▪ Camera: 2

▪ Pixel: 500w

▪ Robotic arm: four-axis robotic arm

Program implementation:

The product uses two red strip lights, and the belt is black and white with double color matching to meet the needs of different product colors. The camera collects pictures, recognizes the edge of the paper, and calculates the offset angle and coordinates. The manipulator completes the picking and fitting according to the offset coordinates.
