How is infrared forehead thermometer produced?

At present, the novel coronavirus epidemic is spreading around the world. Many countries have confirmed that the number of new coronaviruses is increasing every day. In order to take better protective measures, it is very important to keep taking temperature every day. Many qualified manufacturers in the market have turned to produce infrared temperature measuring equipment - Infrared Forehead Thermometer to make contributions to epidemic prevention and control.

The production of Infrared Forehead Thermometer needs dozens of components such as ABS plastic shell, PCB circuit board, IC, resistor, capacitor, infrared sensor, LCD, backlight, battery wire buckle, etc. Besides the three necessary medical certificates, we should also know the basic knowledge of scheme design, product production, etc.

Scheme design and production preparation of infrared forehead thermometer

To design an infrared forehead thermometer, you need to first have a matching shell, LCD screen, sensor and product specifications.

1. How many function keys are there in the shell
2. How many feet does the LCD need
3. Is the sensor digital or analog
4. Product specification: household or medical redundant battery power supply, whether calibration is required
5. Calibration conditions: constant temperature water bath, adjustable constant temperature greenhouse

Basic requirements for production of infrared forehead thermometer

1. Precision constant temperature and humidity chamber
Provide standard site for 25 degree adjustment of the whole machine. In the whole machine debugging process, the infrared probe must be placed in the room for more than 1 hour, so that all parts of the whole machine can reach 25 degrees before the whole machine debugging.

If conditions permit, it can also simulate high and low temperature, high humidity and low humidity environment to test and inspect products. The price of this kind of constant temperature room varies according to different requirements. The cheapest is millions, and the best is over 100000 yuan.
The thermistor can also be calibrated in constant temperature oil bath and water bath.

2. Blackbody infrared temperature calibration source
All such infrared temperature measurement products need to use this blackbody infrared radiation source to calibrate the temperature accuracy before leaving the factory. This kind of radiation source is integrated in blocks. Many high-end products are separated, and most of the middle and low-end products are integrated.

The price of blackbody is about 10000-20000RMB, and the price of imported blackbody is over 100000RMB. We need to make sure it's accurate.

3. Infrared forehead thermometer finished product test bench
In order to ensure the consistency and standardization of test distance and angle, it is necessary to adjust the test bench for mass production. At the same time, the test-bed can also improve the production efficiency.

4. Other supporting tools and common tools
CNC precision adjustable power supply, oscilloscope, multimeter, etc.

5. Software burning debugging equipment (determine whether it is necessary according to the scheme)
Some of them are debugging and calibration through the combination of buttons and screens, some are pure hardware debugging and calibration. This method does not need additional professional debugging equipment, and has low production efficiency and poor consistency.

Part of the solution software interface, using special development and production tools and software for automatic debugging and calibration. This approach must be supported by the original chip manufacturer. At first, it was a bit of a hassle. But the production efficiency is high and the same is good.

If we want to cooperate with the original factory or agent, we usually need a long-term contract or advance payment in the early stage before the original factory or agent start the project.

At present, Hongxiangwen exports all kinds of infrared forehead thermometers with low price and low MOQ.
