Recently, the weather is hot, rainy places! The failure and problems of UVLED curing machines also increase significantly. If the operation is improper, it may cause the machine to work properly, and it can also cause the adhesion of the picture to be unscrupulous, and even the situation of falling off. This affects customers' output and tasks. In the good time of this UVLED curing machine, how to maintain the UVLED curing machine in this season? First of all, the working environment is important! Most of them are heavy rainfall in a short time, accompanied by strong winds. The UVLED curing machine's operation room must be kept dry. The UVLED curing machine must not be placed in a very close position after ventilation from the windows and doors. Pay attention to close the doors and windows to avoid the rainwater from entering the room, increase the indoor air humidity, and the operating room is equipped with air conditioners For equipment, you must turn off the door and window to open the dehumidification function of the air conditioner, because the board card accessories inside the UVLED curing machine belong to the electronic product and are not easy to be corroded by moisture. In addition, if the ground is tide, it is generally difficult to completely dehumidify. You can spread some newspapers and waste books on the ground to absorb water. Many users usually do not pay attention to the storage of materials and often stacked at will. Because the peak of the air humidity in the rainy season is as high as 90%, the air, the ground, and the wall will contain a lot of water. Composition, paper and coatings are suitable for adsorption of water and moisture. Therefore, the printing material should be placed back to the original packaging after each use, and placed on a special shelf in a suspended manner. Do not touch the ground and the wall. How to print the screen is difficult to dry. It is recommended to use the drying heater, or print it. Heat the material before. Because the ink of each manufacturer is different, the color saturation, gorgeous degree and drying time of each ink are different, so the choice of UV printer ink is also very important. It is generally recommended to choose the original ink of the UV printer. The original ink is officially passed through long -term testing, which can make the UVLED curing machine well match with ink. The above points are the precautions of the use of UVLED curing machines and related consumables in a humid climate environment in the rainy season. I hope it will be helpful to you. If you need more help and support, please contact us.

First, no matter what color is positive and negative is fixed. The positive and negative level of the patch LED: Take a serious look at the front of the patch LED. There is a angle in a square or a rectangle. There is a angle of the angle, and the other side is the negative electrode. The positive and negative poles of LED lamp beads: Take a serious look at the front of the LED lamp beads. At both ends of the LED lamp beads, there is a small angle at the end of the LED lamp bead, and the end of the angle is positive and the other end is the negative electrode. LED straw hat lamps are distinguished by the positive and negative electrodes of LED straw hat: The new LED has not been cut, the long foot is positive, the other end is the negative electrode, each manufacturer will be different. If it is packaged by the patch 2512 Or one of the colors is the negative electrode, the bottom is expressed by the triangle, the big head is positive, the small head is the negative electrode, and the large package is positive and negative. Second, you can also use the multimeter Ohm watch. For dial -style multimeter, adjust to“Om X1”When the diode is glowing, the red watch is connected to the positive end of SMDLED, and the black watch is connected to the negative end of SMDLED. Third, because LED opening limits is about 1.5-1.8V. It is possible that the voltage provided by the digital multimeter cannot start it. So look at the mark. The patch emitting dilate (SMDLED) has a negative pole with green dots and is relatively positive. LED energy -saving light positive and negative pole recognition method: The most commonly used method is the multimeter detection method. When using a multimeter to detect the light -emitting diode, you must use it“R×L0K”files. The pipe pressure of the miserable diode is about 3V, and the universal watch is located in“R×Locke”And when the following resistance is blocked. The battery in the table is only 1.5V. Below the pipe pressure drop. Regardless of the positive and reverse access, the light emitting diode cannot be turned on, and it cannot be detected.“R×1”During the file table, 9V (or 15V) high -pressure batteries are connected, which is higher than the pressure drop, so it can be used to detect the light -emitting diode. During the test, the two tablets are connected to the two leads of the light -emitting diodes. The positive pole is connected) to the positive pole;. Then connect the two tablets and the glow diodes. At this time, it is reverse access. If the acupuncture is turned or not moved, the shining diodes have been damaged whether they turn to the head or reverse. Determine the straw hat LED positive and negative pole: inside the LED, the pins connected to the bracket are negative electrodes, and the pins of small bracket links are the positive pole judgment 5050 patch LED positive pole: the entire 5050 patch LED is square, in the four right corners There is a corner with a small scarce angle, which is the place of the small circle. The other right corners do not have a small angle. The end of the small lack of angle is the negative electrode, and the other end is the positive pole. Zhuhai TIANHUI Optoelectronics Technology Co., Ltd. is the development of LED light -emitting diode series of product development, patch LED production processing, sales and service -oriented private enterprises. Products are widely used around computer, communication products, electronic and electric toys, household appliances and lighting fixtures, automotive electronics, medical equipment and many other production areas.

1. The LED chip architecture and raw materials are also one of the factors that affect the thermal resistance of LED dot -light sources, and reducing the thermal resistance of the LED itself is the preliminary condition; The impact of thermal resistance is also great, so the selection of suitable thermal sinking materials is also one of the methods to reduce the thermal resistance of LED components. 3. Even if the same thermal sinking material is used, it is directly related to the size of the heat dissipation area. The secondary heat dissipation design is good and the area is large, which reduces the heat resistance accordingly. Extension has a great effect. 4. LED chip is directly connected to the metal with heat conducting glue, including the different seeds of thermal conductivity and metal will affect the size of the LED thermal resistance. Try to minimize the heat resistance between LED and secondary heat dissipation mechanism loading interface. 5. The working environment temperature of the LED component is too high, and the thermal resistance of the LED component will also reduce the ambient temperature as much as possible. 6. Select a certain technical details such as the material and control rated exchange power to improve the lighting efficiency of LED and extend the LED life as the premise. Simple induction, we must consider the following points when designing the LED point light source module: 1. Reduce the thermal resistance of the chip. LED -side light source LED injection molding module LED light strip LED waterproof irrigation glue module Hongyan cabin three -one cabin three -one heavy work accessories 2. Optimize thermal channel. A. Channel architecture: the shorter the length (L), the better; the larger the area (s), the better; the less the link, the better; eliminate the thermal conduction bottleneck on the channel. B. The heating coefficient of the channel material, the larger the better. C. Improve the packaging process, make the interface contact between channel links more close and reliable. 3. Strengthen the guide/heat dissipation function of the telecommunications channel. 4. Select the light -out -out channel material with higher heat dissipation efficiency.
