ICP DAS DGW-521 is a communication gateway that can stably convert Modbus RTU/DCON to DALI protocols; in this application, the DGW-521 gateway is successfully connected to the customer’s heating system and DALI temperature controller, making their industrial hot air ovens energy- efficient and stable.
In addition, the panel temperature process overcomes various production requirements such as mobile phones, tablets, large-size panels, and automotive panels, creating more flexible production conditions.
Introduction
The client in this case is an equipment factory specializing in the manufacture of industrial ovens and the use of photothermal technology to provide high-precision equipment for various industries. For example, printed circuit boards, flat panel displays (FPD), touch panels, semiconductor industry, electronic assembly, printing, coatings, footwear, etc. The following temperature monitoring case study shows you the application of the ICP DAS DGW-521 gateway in industrial hot-air ovens.
Strict production conditions – oven temperature has become a key factor affecting yield and quality
These methods require a heating process, and the lower the temperature, the better. In addition, precise temperature control plays an important role in each heating process. In the past, when UV glue was processed in a high temperature environment, there would be an aging problem, resulting in the problem of low light transmittance and affecting the yield.
The ICP DAS DALI Gateway, the Connection between PLC and DALI Lighting Control Module
In this case, the industrial hot air ovens are equipped with hundreds of internal lights to generate the heat. To let the light produce the heat along with the process, as well as maintain its stability and reliability, the customer chose the DALI lighting control module to manage the lights, together with the electronic ballast to precisely control the light tube output power. Although the PLC used by the hot air ovens supports Modbus RTU protocol, it is not available for DALI communication protocol.
Therefore, the ICP DAS DGW-521 DALI gateway is a practical device to connect both PLC and the DALI lighting control module to achieve temperature management and light monitoring, maintaining the control of process conditions and yield quality. The system diagram is as follows:
In conclusion
In the past, the hot-air ovens market was monopolized by foreign manufacturers. The hot air multi-function oven produced by this customer broke the long-term dependence on imported equipment, met the needs of improving quality and reducing costs, and led the competitiveness of Taiwan’s photovoltaic industry. The customer is currently the only manufacturer in Taiwan that can supply Array/CF/Cell heaters, and the only supplier in Taiwan’s TFT-LCD device industry.
ICP DAS is committed to the research and development of new technologies, and has a complete range of products to meet the protocol conversion needs of different customers. There is no doubt that ICP DAS will continue to provide a comprehensive range of products and services to our valuable customers through the vast accumulated experience.
