The importance of FRP in robot manufacturing under Industry 4.0

1. Fiberglass robot background

At present, the development of traditional manufacturing industries has entered a bottleneck. The past advantage has now become a stumbling block to the development of enterprises. Even worse, it pushed enterprises to the brink of bankruptcy. How to find a way to change this situation is urgently needed by every enterprise. Driven by industry 4.0, with the integration of artificial intelligence, the Internet of things, digitalization and other new technologies, robots are born. Fiberglass robots have also developed rapidly.

Glass fiber composites are made up of fiberglass and resin. Fiberglass and resin configuration are what determines the specific advantages of a fiberglass product. You can also use carbon fiber to make it if needed. Because fiberglass and carbon fiber are new composite materials. Their specific gravity is less than 1/4 of steel, but the tensile strength is better than steel. As we all know, the tensile strength of carbon fiber can reach more than 3500Mpa, while the tensile strength of fiberglass is 23000 ~ 43000Mpa. Therefore, fiber-reinforced plastics are popular in many fields. For example, fiberglass chair, fiberglass pool, FRP car body and so on. Especially for robots in the livelihood of people and special fields, we also call fiberbots.

Due to strong customization and personalization, the demand for fiberglass shell has grown exponentially in recent years. It makes up for the disadvantages high of cost of traditional robot shell injection mold and limited design. In this case, the use of FRP composite material is helpful. Production processes such as hand-lay FRP, fiberglass filament winding and RTM have effectively solved the shortcomings of this supply chain. This is conducive to helping the development of intelligent robots.

2. Fiberglass application in robotic systems

The following are examples of actual robot products. Our company takes part in the manufacture and supply of some fiberglass robot parts.

2.1 Fire robots

Introduction

On November 20th, officers and men of the fire squadron were practicing the operation of fire robots. This robot is independently developed and produced by our customers. Our company produces the robot shell for our customers. We use other composite materials such as chopped strand mat and fiberglass skin. Because it can increase the strength and corrosion resistance of the robot shell. The robot integrates many functions. For example, wireless video surveillance, fire extinguishing, lighting, high-temperature resistance, and others. It can replace firefighters in high temperature, explosive, and toxic high-risk environments at the scene of a fire.

At the same time, it can also use the high-definition camera to send the scene image. So it can help the firefighters grasp the fire situation in all aspects. Besides, you can introduce a map of the fire disaster area to the robot. So the robot will also go to the disaster location and carry out fire fighting tasks by itself.

Material selection

Since the FRP robot shell is made of fiberglass and resin, it has good high temperature resistance. It will not be damaged in high temperature working environment. During the production process, we chose better epoxy resin than polyester resin to make products.

Why did we choose epoxy resin to make the fiberglass shell? Because the thermosetting property of epoxy resin is higher than that of polyester resin. The hardness and strength of the robot shell are higher. As report goes, in the next three months, they plan to promote Qiteng firefighting robots. Apply them in various fire brigade in our city, and they will soon be in service. From the design drawings to the finalization of the process, our company actively took part in it. Since them, it goes through half a year of trial production and mass production verification with customers. Finally, they put it on the market and won praise from customers.

Professional research

We have made a full investigation and experiment on this robot. The process is from the appearance of the shell to the selection of materials. We put a lot of time and effort into this product, This is an FRP product that we can be proud of. We added the chopped strand mat in the process of making fiberglass robots to increase the strength of the robot shell. Because this is an outdoor product. It has strict requirements on the weather resistance of the product. For example, the UV resistance needs to reach 15 years, and the tensile strength of the product needs to reach 590 Mpa. Thus, we need to choose materials with good tensile strength and UV resistance. As a reinforcing part in composite materials, the fiberglass mat has good insulation and thermal insulation properties. Fiberglass mats can increase the weather resistance of the robot enclosure.

Fiberglass robot shell manufacturing process

Please let me introduce the process and innovation of our production of this robot.

1)Material selection

The customer provided us with a drawing. nd our company researched the drawing and then analyzed the possibility of producing the fiberglass shell. Finally, it was determined that our company could produce the FRP products required by the customer. Let the customer trust us and choose us.

2)Optimizing processes

Our engineers studied the drawings and robot building structures. We actively communicate with customers to coordinate the parts of the process that can be improved and optimized.

3)Hand layup process

After confirming the drawing and the process plan, our company finally chose to use the hand-lay process to produce the product. Why do we choose the most traditional process to produce the shell of this product? This is a result of considering many factors. Including the cost budget, product assembly of large structures, and appearance requirements. The traditional hand layup process maintenance cost is low and repairable. So the use of the hand paste process is more suitable for the production of FRP shell.

4)CNC

We use CNC to produce prototypes, which is a very important step. Because it can guarantee that the final size of the product will not show too much tolerance. Also, it ensures the size and quality of robotic systems.

5) Mold production.

The customer’s surface requirements are almost mirror light requirements. So our company used Japanese Showa imported gel coat when making the mold. As we all know, the price of imported gelcoat is more than six times that of domestic gel coat. To ensure the surface effect of the product, our company does not hesitate to lose part of our profit to achieve customer satisfaction. We also use a reliable release agent in the process. We sincerely hope to help customers get satisfied with products.

6)Choosing the fiber and resin

During the product manufacturing process, our company also conducted an in-depth analysis. It’s main to make the selection of the resin and glass fiber materials. And finally we chose Ashland’s flame retardant grade V0, boulder powder glass fiber felt and the surface felt. We have added fiberglass skin to the material. It can improve the corrosion resistance of the product and increase its service life. Also, we assist customer’s products to provide fire support at the fire site.

7) Sheet metal assembly

Our company adopts precision fixture positioning assembly. So that the customer’s products can be successfully assembled on the internal parts.
