【GIFA 2019】Highly versatile Yizumi Robotic System

 (YIZUMI Booth: Hall 11/G04)

In die-casting industry, it’s a common practice to produce a variety of die-casting products with one die-casting machine. As a result, molds need to be changed often. Therefore, other than the ability of replacing manual operation for a better working environment, the robotic die-casting system should also be able to combine the versatility and stability according to actual circumstances to meet the production requirements of different products to the maximum extent. This is an actual need of customers, as well as a test to the system stability and the design strategy. Under such circumstances, the operation stability and adaptability of the product-extraction and slag-release robotic system inevitably become the choice of customers.  

Yizumi product-extraction and slag-release robotic system is mainly composed of a extractor, along with the peripheral equipment, product integrity detection and confirmation device, slag-release device, conveyer, and safety guard.  

I. The Extractor Robot Bases

In the light of the die-casting work environment, Yizumi employs the KUKA/ ABB / FANUC robot specially designed for die-casting applications with the highest protection level as its product extraction robot. In the meantime, to compensate the mold opening error of the die-casting machine that may cause the biscuit to break off from the die-casting product, the repeated positioning accuracy of the robot can be up to 0.02mm. It is also equipped with the soft float function to ensure the clamping accuracy.

II. Extractor Robot clamper  

While high quality of the robot system is essential, robot clamper is one of the key components that determine whether the product can be held securely. Yizumi’s robot clamper adopts Japanese design concept with independent patent. To meet customers’ demand, Yizumi’s product offers a clamping range that can hold various die-casting products with a biscuit less than φ170 in diameter. Manually change the claw jaws for different products to fulfill the need of picking up different die-casting workpiece. Easy to operate, easy to use.

III. The Valve Box and Pipeline System of Extractor

The robot clamper must have a wide clamping range with strong and powerful clamping force. Equipped with the product-extraction robotic control system - pickup valve box, Yizumi’s robotic arm offers a maximum clamping force of 5970N. The pickup valve box mainly controls the opening and closing of the robot claw. It consists of air filter, pressure relief valve, residual pressure relief valve, pressure switch, ball valve, and air blowing control solenoid valve made by SMC/CKD and other well-known brand pneumatic components manufacturers to guarantee the steady and powerful operation of the product-extraction system.

IV. Machine Frame for the Product-extraction System

As robots are in the state of constant motion during the production process and have to undertake the vibration of die-casting production, the product-extraction robot system must have a solid foundation. To secure the robot, Yizumi uses bolt connection to ensure that the pickup robot frame has a stable base. It is mounted to the floor through expansion bolts or welding approach and requires the ground to have a 300mm thickness of concrete.

V. Product Detector

In order to prevent incomplete extraction of die-casting products due to other causes that may damage the die-casting mold during clamping, the die-casting products must undergo a detector over the integrity of the product biscuit and slag to determine if the extracted product is incomplete. The detector approach can be either contactless photoelectric inspection or contact inspection. Depending on the exterior profile of the product, you may increase the inspection spots and adjust the inspection positions. To prevent pipeline scalding, Yizumi offers as a standard feature the blowing air and pipeline protection devices.

VI. Slag Remove Device

All die-casting products have slag that need to be removed manually which is labor intensive. A robotic slag-release device can remove the slag efficiently. The device has the versatility to remove the slags for the vast majority of die-casting products.

 VII. Product Conveying Device

The product conveying device is used primarily for moving the die-casting products. The product conveying device commonly seen is either belt conveyor or chute conveyor. The standard Yizumi product conveying device is: the positive drive belt conveyor. Depending on your needs, it can come with a cooling fan. Equipped with photoelectric sensors, it can detect and prevent product stacking or collision. The use of frequency conversion motor and frequency inverter makes the moving speed adjustable. Improve the machine operation safety with a moment limiter.

VIII. Safety Fence

As the moving speed is quite fast in the robotic operation, safety fence is the standard equipment for the robot system. Safety fence is generally composed of electronic control measures including a safety door latch, on-site wiring, installation, and safety detection, alarm, and reset device. The primary purpose is to prevent workplace accident and provide protection to production safety.

IX. Control System Cabinet

Yizumi’s robotic system employs the control box made by Mitsubishi or Siemens PLC, and standard color touchscreen, offering features such as fast information viewing, various parameter settings, and alarm detection, etc. The electrical components made by Mitsubishi, Siemens, Omron, and other world renowned brands are used to ensure the reliability of the system.  

In addition to its versatility, the product-extraction and slag-release robotic system is also expandable and upgradeable to have features such as product cooling, trimming, and marking.

As a unique die casting machine and integrated robotic system supplier, we can offer customers who are in the die casting filed better robotic system solutions to fulfill customers’ production demands on multi-functional and multi-leveled intelligent automatic system.
