First, the design principle of the machine automation system for loading and unloading of machine tools:
Because the transformation project is carried out under the existing conditions of the factory floor, compared with the new project, it will be subject to many objective conditions. Therefore, the engineering project 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.
2, economical. Focusing on the cost-effectiveness of the project, under the premise of meeting the requirements of automated production, due to its simplicity, it does not seek luxury, spends as little as possible, and saves on renovation costs.
3, maximize. With the same renovation costs, we can do our utmost to improve the degree of automation and automation, and increase production with little or no labor.
Second, the machine tool automation project flexible solution:
Because the renovation project is carried out under the existing conditions, it is necessary to solve key issues flexibly:
1, the choice of industrial robots. According to the effective height of the workshop, production beats, use gantry (truss type) or articulated robots.
2. The layout of robots and machine tools: Machines and robots on the automation of processing units and production lines, according to the site area of ​​the workshop, under the premise of improving the production cycle, adopt L-shaped, ring-shaped, “product†characters, and “1†respectively. "Word layout.
3, while the production, while the transformation. The installation and commissioning of the loading and unloading robots are separated from the machine tools, so that the production and transformation are correct.
In the silicone industry, to meet the user experience of the majority of consumers, multi-color products have always been the best-selling products, the process is used in silicon materials bonding and plastic bonding.
1. Soft and hard plastic two-color design
The two materials must have a certain temperature difference in the melting point. Generally, it is recommended to reach 60°. It is recommended to be at least 30°. The melting temperature of the first shot material is high. Generally, the first shot is PC or PC/ABS, and the second shot is TPU or TPE, PC thickness is 0.6-0.7mm, soft rubber part thickness is required to be 0.4mm or more.
Try to widen the contact area, make grooves to increase the adhesion, or use the core for the first shot, and the second part of the material is injected into the first shot. The surface of the first shot is as rough as possible.
2. Material compatibility
Multi-color injection molded mating materials must meet two basic compatibility conditions. They are compatible with the adhesive compatibility and processing.
3. Transparent and non-transparent two-shot design
(1) Double shot design of small lenses
The first shot is non-transparent, and the second shot is made of a lens. The first shot uses a PC with a high melting point and the second shot uses a PMMA.
(2) Transparent and non-transparent bijective design for decoration
The first shot is a non-transparent material, the second shot is a transparent material, and the non-transparent material is generally a high temperature of the PC material of SABIC, and the second shot transparent material is PMMA or PC. The PC needs to be sprayed with UV to protect it. PMMA can choose uv or fortification. If there are characters on the surface, you must choose UV
In the silicon bonding area, several silicon materials will be used to achieve different color silicon, different rubber components, so the multi_k color process is commonly used and is quite popular.
