Description

Technical Field

[0001] The utility model belongs to the technical field of automatic control, and in particular relates to a data sampling device for follow-up detection of a paint robot. Background Art

[0002] With the rapid development of science and technology and the increasing development of industrial automation, technological innovation in automobile production lines continues to promote the improvement of production efficiency. Among them, the widespread application of robotics technology is one of the most significant manifestations. With the rapid development of the automation industry, more and more automobile manufacturers have begun to use robots to follow the movement of the car body to detect scratches and exterior damage. The introduction of this technology has undoubtedly brought great changes to automobile production.

[0003] Traditional vehicle body damage detection mainly relies on manual visual inspection, which is not only inefficient but also easily affected by human factors, resulting in inaccurate detection results. The emergence of robot-following vehicle body motion technology has completely changed this situation. By adopting advanced robot technology and image recognition technology, the robot can track the movement trajectory of the vehicle body in real time and accurately detect various parts of the vehicle body. This automated and intelligent detection method greatly improves detection efficiency and reduces errors caused by human factors.

[0004] However, in the actual production process, automobile manufacturers often have multiple production lines, which requires multiple robots to work simultaneously. In order to ensure the accuracy and consistency of detection, each robot needs to have accurate positioning points so that it can accurately track the movement trajectory of the car body. However, as the number of inspection items continues to increase, the robot's follow-up inspection range may be limited. When the robot cannot cover all inspection areas, it is necessary to consider other ways to solve this problem.

[0005] In addition, when the robot is idle, if the car on the production line has passed the synchronization switch, the product needs to be abandoned, which will lead to missed inspections. To avoid this, automobile manufacturers need to take a series of measures to improve the efficiency and coverage of robots.

[0006] In summary, although the application of robot following body motion technology in automobile production lines has achieved remarkable results, it still faces some challenges and problems in the actual production process. In order to overcome these challenges, it is of great significance to design and develop a data sampling device for paint robot following detection. Utility Model Content

[0022] Compared with the prior art, the advantages and positive effects of this application are:

[0023] The utility model sets encoders and synchronous switches in advance around the conveyor line, and realizes real-time monitoring and precise control of the running status of the conveyor line through advanced ABB tracking board technology.

[0024] First, encoders, as a high-precision measuring device, are installed at key locations on the conveyor line to collect real-time information about the running speed of the conveyor line. These encoders convert the speed data of the conveyor line into electrical signals through precise measurement and calculation, and transmit them to the controller through the ABB tracking board. Based on the received speed information, the controller can accurately grasp the running speed of the conveyor line in a timely manner to ensure that the conveying speed of the product is coordinated with the overall rhythm of the production line.

[0025] The purpose of the synchronous switch is to ensure the accurate positioning of the products on the conveyor line. These switches are installed at specific locations on the conveyor line. When the product passes by, it triggers the switch to close or open, thereby generating an electrical signal. This electrical signal is transmitted to the controller to determine the specific position of the product on the conveyor line. By combining it with the speed information provided by the encoder, the controller can accurately grasp the current position and movement status of each product.

[0026] As the core component of this system, the ABB tracking board is responsible for receiving and processing the speed information output by the encoder and the input information of the synchronous switch. It has powerful data processing capabilities and high-speed communication performance, and can transmit this information to the controller in real time. Based on this information, the controller can accurately control the running speed of the conveyor line and the position of the product, thereby realizing comprehensive monitoring and data collection of the products on the production line.

[0027] The utility model realizes real-time monitoring of the running status of the conveyor line and control of the robot. It can not only timely and accurately grasp the running speed of the conveyor line and the current position of the product, but also trigger the corresponding robot to perform follow-up detection based on this information. This follow-up detection method can ensure that the robot detects and processes the product at the correct time and position, thereby further improving production efficiency and product quality.

[0032] See also Figure 1 , a data sampling device for follow-up detection of a paint robot, comprising:

[0033] M robots are equipped with N sensors for sampling data on the paint surface of the products on the conveyor line. The M robots are distributed in a preset area around the conveyor line; each sensor is connected to the corresponding robot control unit via a data cable; in a specific automated production line application scenario, the M robots are distributed in a preset area around the conveyor line, responsible for sampling data on the paint surface of the products on the conveyor line, mainly for image acquisition. The sensor can be a two-dimensional image sensor and / or a three-dimensional vision sensor. The two-dimensional image sensor is mainly used to capture the planar image information of the product, while the three-dimensional vision sensor can obtain the three-dimensional structure data of the product. Through these sensors, the robot can more accurately identify the shape, size and surface quality of the product, providing strong data support for subsequent operations.

[0034] L encoders are installed at the first preset point on the conveyor line. The main function of the encoder is to collect the running speed of the conveyor line and the current position information of the products on the conveyor line. In terms of selection, incremental encoders are preferred due to their high precision and high reliability. Through the data provided by the encoder, the robot can understand the running status of the conveyor line in real time, thereby adjusting its own movement speed and position to ensure synchronization with the conveyor line.

[0035] P synchronous switches are installed at the second preset point around the conveyor line to collect the starting position of the product on the conveyor line for information sampling; when working, once the synchronous switch detects that the product on the conveyor line has reached the specified position, it will send a signal to the robot through the ABB tracking card to instruct it to start information sampling. The through-beam photoelectric switch is preferably used in such scenarios because of its fast response speed and good stability.

In terms of selection, the DSQC377B model ABB tracking board is highly favored due to its high performance and easy integration. The board is connected to the robot through a controller. The controller usually uses a network computer with an image processing module installed to ensure real-time processing and transmission of data. Among them:

[0037] The ABB tracking board is connected to each encoder and each synchronous switch respectively; the ABB tracking board is connected to the robot through a controller; the controller can be a network computer equipped with an image processing module; wherein:

[0038] L, M, N and P are all natural numbers greater than 0.

[0039] In summary, this application realizes efficient and accurate data collection of products on the conveyor line by comprehensively using hardware devices such as sensors, encoders and synchronous switches, as well as data processing units such as ABB tracking boards. This not only improves production efficiency and reduces labor costs, but also improves product quality and customer satisfaction. With the continuous advancement of technology and the in-depth expansion of applications, it is believed that robots will play a greater role in more fields in the future.
