wococarbide.com talks about the mainstream spraying lines that are common in factories now

       1. Manual spraying line: Advantages: It is easy to apply to spraying of various workpieces (size or special-shaped); convenient protection, low cost of protection, low difficulty of protection skills; less floor space. It is not only convenient for small batch production, but also suitable for larger batch production. Defects: When mass-producing workpieces of the same size, the repetitive labor that occurs in the turnover of the workpieces between the various processes occupies a relatively large amount of labor, and it is impossible to greatly increase the output value or greatly reduce the labor cost.











2. Semi-automatic spraying line: Advantages: When spraying a single type of workpiece in large quantities, it can greatly reduce the labor cost and energy consumption of a single piece, and has a large daily production capacity; the investment is much lower than that of the automatic spraying line, and the protection The cost and difficulty are also much lower; the production capacity is close to that of a fully automatic spraying line. Defects: It is not suitable for small batch spraying of special-shaped workpieces. Too small batches will still cause high energy consumption per piece, which will make the spraying cost too high; when the spraying line speed is fast and the continuous spraying time is long, the labor of spraying operators Great strength.











3. Fully automatic spraying line: Advantages: When spraying the same workpiece in large quantities, it has a considerable advantage in daily output value, and the labor cost and energy consumption of a single piece also decrease with the increase of output value. Defect: The energy consumption of small batch production is very high, that is to say, the assembly line cannot be started if the workpiece cannot reach a certain number, otherwise the spraying cost will be doubled or even dozens of times increased; it is only suitable for spraying of workpieces whose volume and shape specifications are within a certain range. , the workpieces with special shapes or inappropriate sizes cannot be sprayed; the protection skills of the pre-treatment link are difficult, and the pickling link of the workpieces still needs to be completed before going online; the protection operations are messy, the protection costs are high, and the protection skills are difficult; the floor space is large. It is suitable for spraying fixed workpieces in large quantities for a long time.











About automatic spraying production line - introduction of automatic spraying robot







The repeatability of the spraying robot For the gluing robot, the repeatability is required to be high, generally reaching 0.5mm. For painting robots, the repeatability requirements are relatively low, and now the painting robots of major companies can meet the general requirements, such as Rongde's painting robots.







3. The movement speed and acceleration of the robot The greater the maximum movement speed or the maximum acceleration speed of the painting robot, the shorter the idle travel time of the robot, and the longer the certain operation time of the painting robot under a certain rhythm. The utilization rate of spraying robots has been improved. It should be pointed out that the movement speed of the robot is accustomed. In the process of spraying, the movement speed of the spraying tool is directly related to the characteristics and materials of the spraying tool, and needs to be set according to the process requirements. In addition, because the technical indicators of spraying robots are related to their prices, robots with high cost performance should be selected according to the production scale and process requirements.







4. The maximum load accepted by the robot arm is determined according to different spraying occasions, the spray equipment configured in the painting or gluing process, etc., to determine the maximum load accepted by the spraying robot arm. Sometimes in the process of spraying small workpieces, the robot arm is also used to lift the small workpieces for transfer after the paint is sprayed.
