CNC lathe robot automatically loading and unloading

First, the customer situation:

The customer is a foreign-owned enterprise that produces electric motors in Shandong. The factory has more than 1,500 employees, more than 300 CNC machine tools, and an annual output value of 300 million yuan for special motors. It is a company that is in a crucial period of equipment refinement.

Second, automation needs:

Because most of the products are exported to foreign countries, companies face the pressure of renminbi appreciation, large output, heavy workpieces and labor, and the continuous increase of raw materials and workers' wages, resulting in continuous increase in production costs. The customer wanted to replace the manual loading and unloading with robots by changing the current lathe operator-intensive traditional production methods to realize high-volume automated processing, improve the economic efficiency and profitability of enterprises, and enhance the ability to participate in international competition.

Third, the solution:

This is an automatic transformation project of CNC lathes, so the project is carried out under the existing conditions of the factory floor. Compared with the new projects, it will be subject to many objective conditions.

(a) The principle of project automation system design must be:

1, personalized. To meet the actual needs of the plant, it can fully meet the needs of automated production and solve key problems. The key points of this project are the labor intensity, low efficiency, and unreasonable logistics turnover.

2, economical. Focusing on the cost-effectiveness of the project, under the premise of meeting the requirements of automated production, it is simple because of simplicity, not seeking luxury, and spending as little as possible to save on renovation costs.

3. Maximize: Do your best to improve the degree of automation and automation, and use less or no labor to increase production.

(b) Establishment of an automated turning machining unit:

By establishing an automated turning machining unit, it is possible to satisfy the large-volume automated processing of double-sided motor shafts.

1. The composition of the automated turning processing unit: Two CNC lathes are serviced by one robot.

2. Layout of automated turning processing unit: According to the site requirements of the factory, the CNC lathe adopts a right-angle structure, and the robot is installed in the middle of the enclosure formed by the CNC lathe, which is conducive to improving efficiency and saving space and space.

3, the robot selection: the workpiece diameter of 60-150mm, the weight does not exceed 10kg, mainly to complete the two turning operations. For multiple models of customer's workpieces, relatively complex gripper fixtures need to be designed, and the FANUC M-710iC/50 robot is most suitable.

4. Feeding system configuration: Feeding adopts double station tray feeding. When the A station processing is completed, the robot will automatically switch to B station to take the material and process. The worker only needs to replace the tray, once filling, can satisfy Processing 8 hours. Between two CNC machine tools, the commutation is performed in the form of a flip table.

5, Handle design and manufacturing: According to the customer's workpiece shape, weight, independent design of multi-functional type for customers can take into account the six kinds of different sizes of hand grips, with a simple type, easy maintenance, low cost characteristics.

6, security protection: the system work area is forbidden to enter, so the system is completely isolated by the security guardrail, and configure the security door system, when the door is not normally open, the robot emergency stop and alarm, some people work in the motion area, the robot prohibits circulation start up.

Fourth, the project effect

1. After processing with a robot, the device can save five people, while reducing the labor intensity of workers, and the introduction of advanced equipment, greatly enhancing the company's image.

2, to improve production efficiency, we must control the beat of production. In addition to the fixed beat of production and processing can not be improved, automatic loading and unloading to replace the manual operation, so that you can control the beat well, to avoid the impact of human factors and the production beat, greatly improving the production efficiency, achieved Automated large-volume processing.

3, product quality has been guaranteed. Automatic robotic production line, from the feeding, clamping, and cutting are completely completed by the robot, reducing the intermediate links, greatly improving the quality of parts, especially the surface of the workpiece is more beautiful, and the stability of the quality is guaranteed.
