Description
Technical Field
The utility model belongs to the technical field of industrial robot, concretely relates to Scara robot high accuracy low-cost speed reduction module.
Background
The rapid development of industrial robots has been promoted by the introduction of "china manufacture 2025" and industry 4.0. Since 2010, the global industrial robot market has continued to grow in size; china manufacturing enterprises mostly adopt extensive development modes as main points; with the improvement of the product quality requirements of people in the future, the industrial manufacturing industry in China is also upgraded towards intensification and intellectualization, the automation degree is higher and higher, meanwhile, with the continuous change of the population structure in China, the population dividend gradually disappears, and the demand on the automation equipment represented by industrial robots is larger and larger.
industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices oriented to the industrial field, can automatically execute work, and are machines which realize various functions by means of self power and control capacity.
The upper core parts of the robot are provided with a controller, a servo motor and a speed reducer; in terms of cost, core parts account for about 72% of the cost of an industrial robot and are a main source of profits in the robot industry, but at present, only a few of domestic robot enterprises have advanced technologies and can independently produce the core parts, and most of the core parts of the robot enterprises depend on import (taking a servo motor as an example, foreign brands account for nearly 80% of market share of the China servo market); therefore, the cost of the domestic industrial robot is high all the time. However, with the increasingly narrowing gap between the research and development of the domestic brand technology and foreign enterprises, the competitiveness of the domestic brand gradually develops, and the tendency of the localization of core parts is emerging in the future (the market share of domestic small servo motors has increased to about 20%).
Scara robots are a branch of industrial robots. The third shaft (end effector rotating shaft) of the Scara robot has the following structures: 1. the servo motor directly drives the composite screw rod to rotate through the synchronous belt; 2. the servo motor drives the composite screw rod to rotate through the precision planetary reducer and the synchronous belt; 3. the hollow motor directly drives the composite screw rod to rotate; 4. Driven by separate screw rods.
The development of domestic robots is rapid, the technology is mature, and the popularity is higher and higher. However, there are the following problems: 1. the high-precision robot has the advantages that the cost of core parts of the high-precision robot is high, the manufacturing period is long, the overall cost of the robot is high, and certain cost pressure is brought to small enterprises to introduce the robot. 2. The servo motor directly drives the composite screw rod to rotate through the synchronous belt, and due to the fact that the synchronous belt has certain elasticity, if the end effector of the robot is large in load and large in inertia, when the robot runs at a high speed, the precision of the end effector can be affected. 3. The servo motor passes through accurate planetary reducer, and the rethread hold-in range drives compound lead screw rotatory, and the load capacity of robot is direct relatively and is driven through the belt, and load capacity has obtained very big improvement, but accurate planetary reducer cost is too high, influences the profit of robot producer and the cost of robot application producer.
