Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of robot welding, in particular to an intelligent production line for preheating and heat preservation of wear-resistant steel plate and a production method thereof. BACKGROUND

[0002] In the current industrial production field, the manual welding production process of conventional wear-resistant steel plates has many drawbacks, which seriously restricts the improvement of production efficiency and the stability of product quality. As for manual welding, a manual grinding process is first needed, which requires operators to spend a lot of time and effort to use grinding tools to carefully grind the welding parts of the steel plate to ensure the flatness and smoothness of the welding surface, thereby providing a good foundation for subsequent welding work. However, this process is not only labor-intensive, but also inefficient, and is easily affected by human factors, such as the uniformity and intensity of grinding, which can lead to uneven welding quality.

[0003] After completing the manual grinding, the next step is the assembly process. Operators need to rely on experience and visual observation to accurately position the steel plate components to be welded, ensuring that the gap, angle, and other parameters between the components meet the welding requirements. This process also requires a high degree of concentration and patience, and any deviation can affect the strength and stability of the entire welded structure. Moreover, since it is a manual operation, the assembly speed is relatively slow, making it difficult to meet the needs of large-scale production.

[0004] When entering the welding stage, the problem is more prominent. During the welding process, the steel plate rapidly absorbs a large amount of heat, causing its temperature to rise sharply. At the same time, the strong light, high-temperature radiation, and harmful smoke generated by welding make the welding environment extremely harsh. Operators working in such an environment not only easily become physically tired, but also expose themselves to harmful environments for a long time, which can pose a potential threat to their health. These harsh working conditions greatly limit the work efficiency and work duration of operators, and thus become one of the key factors restricting the improvement of welding efficiency.

[0005] In addition, due to the special material properties of the wear-resistant steel plate, preheating treatment is required before welding, and heat preservation operation is required after welding is completed to ensure the stability of the organizational structure of the welding part and avoid quality problems such as cracks and deformation. However, the traditional preheating method usually uses a conventional oven for heating, which has the defect of long preheating time. It often takes hours or even longer to heat the steel plate to the appropriate welding temperature, which undoubtedly greatly increases the entire production cycle. Moreover, in actual production process, due to the need to accurately control the pre-welding temperature to ensure the welding quality, the temperature control accuracy of the conventional oven is relatively low, which is difficult to meet this requirement. This has resulted in the incompatibility of the conventional preheating method with the advanced welding robot automatic production system, which has greatly limited the application of welding robots in wear-resistant steel plate production.

[0006] In view of the various problems existing in the conventional wear-resistant steel plate welding production method, and with the increasing demand for efficient and high-quality welded products in industrial production, there is an urgent need in the market for a welding wear-resistant steel plate intelligent production system that can solve the above problems. Such a system should have efficient grinding, assembling and welding functions, be able to significantly improve production efficiency while ensuring welding quality, and be able to accurately control the welding temperature, whether preheating or post-welding heat preservation, to meet the special process requirements of wear-resistant steel plate, thereby bringing higher economic benefits and market competitiveness to wear-resistant steel plate production enterprises, and promoting the technological progress and development of the entire industry.

[0074] The loading platform for scaffolding is used for loading small scaffolding, and the loading platform for wear-resistant steel plates is used for loading large wear-resistant steel plates. The loading platform can be connected to the electric trolley for power-assisted transportation by removing the manual handrail through the disassembly pins. Figure 6 The upper surface of the wear-resistant steel plate loading platform is provided with slotted holes for placing positioning pins.

[0075] The laser cleaning system uses a pulsed laser combined with a robot to remove rust and paint from wear-resistant steel plates. The system includes a cleaning platform. The laser cleaning head is integrated into the robot's gripper. The robot uses rotational movement to position product parts placed on the cleaning platform, and robot instruction programming identifies the areas requiring rust removal.

[0076] The robot's magnetic gripper moves the product components from the loading trolley to the laser cleaning platform, where laser cleaning begins. The cleaning location is the weld surface.

[0077] The laser cleaning system also includes a protective plate, on which an observation window is provided; and a smoke exhaust port is provided on the top of the protective plate.

[0082] Table 1

[0083]

[0084] Induction heating:

[0085] 1. The heating device detects the real-time heating temperature of the workpiece through a sensor and displays it on the HMI main interface;

[0086] 2. The device detects that the workpiece is heated to 200 DEG C and stops heating, and then diffuses and heats again until the temperature range is reduced to the required range, and records the cumulative heating time at this time, and the heating time is the heating time;

[0087] 3. After the heated steel plate enters the holding stage, the device enters the holding mode, and the temperature difference between the surface temperature and the center temperature of the steel plate is controlled within 8 DEG C through the minimum holding time, and the holding time can also be extended according to the beat time, and the longer the workpiece temperature is more uniform;

[0088] The heating curve is as shown in Figure 22 .

[0091] The three-dimensional vision of the present application can identify the position of the workpiece on the feeding table, and guide the robot gripper to grab. The vision system at the welding station plays a role in positioning the workpiece and guiding the robot gripper to place small parts relatively accurately. Laser sensing further identifies and positions the weld position, and guides the welding robot to perform welding work.

[0092] The vision of the present application is used to guide the robot, and different stations correspond to different templates. The templates for the cleaning station, the heating station and the discharging station are four kinds of templates for taking large parts, templates for taking large parts, templates for taking small parts once, templates for taking small parts twice. Through the difference of the workpiece characteristics, the accuracy of visual detection is high.

[0093] The template needs to be determined in advance. The photographing position of the robot feeding is determined in advance. The vision software takes a photo at the photographing position. The vision software selects the vision detection area, and smears the workpiece characteristics. After completing the template, the robot slightly moves to verify the stability of the detection template.

[0094] The splicing is picked up by the carrying robot gripper and the welding robot cooperates to carry out spot welding, and then the welding robot carries out full welding after accurately identifying the weld through the laser sensor.

[0095] The intelligent splicing and welding system can also set up a three-axis rotary displacement platform for other welding.

[0096] The blanking support bracket adopts buckle positioning, and the blanking area is wrapped by the heat preservation material as a whole to delay the cooling of the welded part.

[0097] The product component on the horizontal rotary position changing platform is carried to the heat preservation room by the carrying robot magnetic tool gripper, the heat preservation room roller shutter door is opened, the carrying robot puts the product component on the blanking support bracket, and the carrying robot exits, and the heat preservation room roller shutter door is closed.

[0098] The production line starts to work:

[0099] ① The carrying robot carries the wear-resistant steel plate to the laser cleaning platform;

[0100] ② The laser cleaning head integrated with the carrying robot starts to clean the wear-resistant steel plate;

[0101] ③ After cleaning, the carrying robot carries the wear-resistant steel plate to the induction heating platform;

[0102] ④ The induction heating platform starts to heat the wear-resistant steel plate;

[0103] ⑤ The carrying robot moves to the feeding platform to identify and grab the small butt, and moves to the welding horizontal rotary position changing platform to carry the welded wear-resistant steel plate to the heat preservation room blanking support bracket;

[0104] ⑥ After induction heating, the carrying robot carries the wear-resistant steel plate to the welding horizontal rotary position changing platform;

[0105] ⑦ The carrying robot cooperates with the welding robot to spot weld the small butt to the wear-resistant steel plate;

[0106] ⑧ The welding robot starts to weld, and the carrying robot repeats step ①.
