Sign Welding Robot

Product introduction

1.    Equipment Overview

The sign welding robot is a multifunctional intelligent automation system specially developed for the bar production line of iron and steel enterprises, which integrates automatic weighing, automatic positioning, automatic data entry, automatic printing of product signs, and automatic welding signs. The product not only adopts integrated design, 3D image recognition, component modular design, and standardized process production, but also occupies a small area and has high speed; Replacing the traditional production process with manual printing of labels, manual data input, manual welding of signs and other cumbersome operations, this product avoids potential safety hazards for on-site workers, and eliminate man-made errors in printing signs, data entry, welding signs, etc. which reduce labor and labor intensity of operators, and meet the needs of high-paced and high-intensity production

Welding Robot

The robot completes the printing, taking, and welding of two signs in 25s.

If customer needs it, the robot can also complete the bundle review work (optional).

2.   Design Conditions

3.   Equipment function and technical parameters

3.1 Main technical function

(1) It can realize sign printing and cutting,and the data on the sign comes from MES, secondary automation, metering system,The identification data is arranged in order andis automatically printed according to the set order, and at the same time, it can execute the printing action according to the second-level printing signal;The bars are conveyed in the ordercorresponding to the data, reach the automatic welding area of the robot, stopautomatically, wait for the completion of the welding operation of the robot,and then continue the downstream conveying.

(2) It can realize the detection of signs,automatic sign arrangement, and automatic positioning of signs;

(3) The manipulator can automatically take cards, clip cards, and withdraw cards;

(4) It can realize automatic identification of bar position and automatic sign welding;

(5) It can realize automatic sorting, delivery, and withdrawal of welding nails;

(6) Real-time monitoring of the operation of the system and real-time alarm for abnormal situations;

(7) It can realize the function of re-inspection of the number and count of steel bundles, and the re-inspection number and results are transmitted to the secondary system of the production line;

(8) It can realize the high temperature and dust protection functions of the robot;

(9) Provide the independent HMI screen and access control center;

3.2 main technical parameters

(1) One-time welding success rate: ≥ 99.7%;

(2) Number of welding plates: 2 pieces/bundle, flush end welding, welded in the center of the end face of the bar;

(3) Completion time of welding two signs at two ends: ≤ 15s, and completion time of welding two signs at one end: ≤ 25s;

(4) Equipment operation rate: ≥ 99.8%;

(5)  Recognition rate of welding point of vision system: 100%;

(6) Capacity of automatic nail feeding system: > 10pieces / min;

(7) Re-inspection accuracy of steel bundle number: 98% / (calculated by bundle

4.   System Composition

The welding plate system is mainly composed of a six-axis industrial robot, a 3D visual recognition system, a steel bundle re-check welding system, a welding nail sorting device, a label printing, a positioning device, a safety protection system, an electrical control cabinet, a local console (with the function completely consistent with HMI) and operation control software and hardware.

(1) The six-axis industrial robot is used as the action platform, which can achieve the function of multi-angle free welding. The system is equipped with first-line brand robots.

(2) The special label printer is adopted. The printing and labeling series system is reliable, flexible, and solid. It can communicate with the production line data and can be configured for various applications. It can print ordinary numbers, letters, ASCII codes, one-dimensional codes, and two-dimensional codes.

(3) The automatic plate welding machine applies advanced microcomputer processing technology to control the welding sequence and the energy released by the energy storage capacitor. It can instantly weld and hang the steel plate on the end face of the steel so that the position of the steel plate is obvious and does not damage the integrity of the base metal.

(4) Automatic nail feeding system: nail splitting mechanism, direct vibration flat feeding mechanism, high reliability. The vibration control adopts the intelligent digital pressure regulating vibration feeding controller of cut, which controls the disc feeder and the vibration nail feeding straight slide to complete the nail feeding to a fixed position for the robot to take the nail. For the fault tolerance of the nail feeding device, the success rate of the nail feeding device reaches 99.99% when the specification of the nail reaches the design standard of the nail.

(5) Label printer and welding nail feeding device have automatic thermal switching function of one for use and one for standby, which can be combined freely.

(6) The control cabinet and robot are equipped with a high temperature and dust protection system, which can effectively prevent the impact of high temperature and dust on the system.

(7) The automatic plate welding system has the function of rechecking the number of finished steel bundles. The detected number is compared with the number of steel bundles of corresponding specifications. If there is any abnormality in the steel bundle, it will remind the manual recheck with audible and visual alarm on the control screen and on-site (optional).
