Household electric hidden door, linear guide rail used in the office door working principle:
It can be understood as a kind of rolling guide, which is an infinite scrolling cycle between the slider and the guide rail by the steel ball, so that the load platform can easily and linearly move along the guide rail with high precision, and the friction coefficient can be reduced to that of the conventional slide guide. One-fiftieth, it can easily achieve high positioning accuracy. The design of the terminal unit between the slider and the guide rail enables the linear guide rail to simultaneously bear the loads in all directions such as up, down, left, right, etc. The patented reflow system and the simplified structure design allow the HIWIN linear guide to have smoother and lower noise movement.
Slider - Makes movement from curve to line. The new rail system allows the machine to achieve a rapid feed rate. With the same spindle speed, fast feed is the hallmark of linear guides. Linear guides Like flat guides, there are two basic components; one is the fixed element that serves as the guide and the other is the moving element. Since the linear guide is a standard part, the only thing that needs to be done by the machine tool builder is to machine the parallelism of the plane of the mounting rail and the calibration rail. Of course, in order to ensure the accuracy of the machine tool, a small amount of scraping of the bed or column is essential, and in most cases, the installation is relatively simple. As a guide, the guide rail is hardened steel, which is placed on the mounting plane after fine grinding. Compared with the plane rail, the geometric shape of the linear rail cross section is more complex than the plane rail. The reason for the complexity is that the groove needs to be machined to facilitate the movement of the sliding element. The shape and quantity of the groove depend on the machine tool to be completed. The function. For example, a rail system that can withstand both linear and dian-overload moments is very different in design compared to rails that only accept linear forces.
Chamber door use range:
The secret room door can be widely used in silver villas, high-end apartments, offices, high-grade office buildings, museums, art galleries, tax bureaus, public bureaus, shopping malls, supermarkets, department stores, factories, enterprises and institutions.

Shanghai Tianqi Service Commitment:
In order to create brands, improve corporate reputation, and establish a corporate image, we are guided by the spirit of "all the pursuit of high quality, customer satisfaction for the purpose of" and "promise the price, good service, reliable product quality," the principle of solemn promise to you :
(1) Service tenet: fast, decisive, accurate, thoughtful and thorough
(2) Service goal: Service quality wins customer satisfaction
(3) Service efficiency: During the warranty period or outside the warranty period, if there is a problem with the equipment, after the supplier receives the notice, the maintenance personnel can reach the site and begin maintenance within 24 hours.
(4) Service principle: The warranty period of the product is 12 months. During the warranty period, the supplier will repair and replace the damaged parts caused by the quality for free. The damaged parts and components will be charged only after the warranty period. Equipment damage caused by demand-side human factors, suppliers repair or provide accessories are based on the cost price. Outside the warranty period, our technical staff visits from time to time to investigate user usage.

LED Packages
LED Packages
LED (semiconductor light-emitting diode) packaging refers to the packaging of light-emitting chips, which is quite different from integrated circuit packaging. The packaging of the LED is not only required to be able to protect the wick, but also to be able to transmit light. Therefore, LED packaging has special requirements for packaging materials.
Generally speaking, the function of the package is to provide sufficient protection for the chip to prevent long-term exposure or mechanical damage to the chip in the air to improve the stability of the chip; for the LED package, it also needs to have good light extraction efficiency and good heat dissipation. , A good package can make the LED have better luminous efficiency and heat dissipation environment, and then improve the life of the LED.
1. Expand the crystal, open the densely arranged chips a little bit to facilitate the crystal bonding.
2. Die-bonding, point conductive/non-conductive glue on the bottom of the holder (conductivity depends on whether the chip is a top-bottom PN junction or a left-right PN junction) and then put the chip into the holder.
3. Short bake, so that the chip does not move when the glue cures the bonding wire.
4. Wire bonding, use gold wire to connect the chip and the support.
5. Pre-test, preliminary test whether it can be bright.
6. Fill the glue and wrap the chip and the bracket with glue.
7. Bake for a long time to allow the glue to solidify.
8. Post-test, test whether it can be bright or not and whether the electrical parameters meet the standard.
9. Light and color separation to separate products with roughly the same color and voltage.
10. Packaging.
