Analysis of the standard of fingerprint lock production equipment under German technology
As a new hot industry in the world, fingerprint lock has developed in the Chinese market for several years. Its convenience, intelligence and security have been recognized by more and more users. However, from the current market reaction, The quality assurance problem of fingerprint locks is still a knot that many buyers are difficult to solve. The Analects of Confucius have a cloud: "If a worker wants to do something good, he must first sharpen his tools." A company's production equipment and process standards largely determine the quality of the product. Consumers want to unravel this knot and also study the various brands from this perspective.
At present, German craftsmanship has always been synonymous with quality assurance in various industries. Therefore, here we take the representative brand of German fingerprint lock DESSMANN as an example to help consumers analyze the selection of fingerprint lock products from the perspective of product equipment guarantee. Purchase standard. Different from the fingerprinting company in the Lingnan system of "assembly center" on the market, DESSMANN is a fingerprint lock manufacturing enterprise with heavy fixed assets. It has invested heavily in R&D, production, testing and sales. An integrated modern smart lock development center. Through the reporter's visit, let us know in detail what a professional international fingerprint lock brand depends on which equipment to ensure the quality of its products.
First of all, the most impressive part of the visit was the zinc alloy die-casting machine on the first floor of the DESSMANN plant. According to reports, the machine is currently the most advanced 280-ton hot chamber zinc alloy die-casting machine, the degree of automation is very high. The number of possessions in the country is very small, and the manufacturing companies in the lock category are even rarer. According to the company's manufacturing director, the zinc alloy die-casting industry is a very polarized industry. On the one hand, most of the die-casting manufacturers are workshop-style enterprises, the operation process is not standardized, and the quality cannot be guaranteed. On the Other hand, a very small number of regulated companies in the industry are large or very large companies, and will not be processed for other manufacturers. Based on the characteristics of the zinc alloy die-casting industry and the strict quality requirements, DESSMANN has established a zinc alloy die-casting workshop. In this way, through self-production and quality monitoring, the "shell", one of the three components of the fingerprint lock, has a fundamental guarantee of quality.
The other of the three components of the fingerprint lock is the electronic circuit board part, whose quality requires a strict aging test to detect. In the electronics workshop, we saw a professional aging laboratory. DESSMANN Fingerprint Locks All electronic boards will enter the lab for aging testing after the patch is completed. DESSMANN's aging test has several advantages over other manufacturers:
1. The aging test takes more than 72 hours after all the circuit board patches are completed.
2. The temperature of the aging chamber is constantly controlled between 55° and 58°.
3. During the aging test, all the circuit boards are not only powered on, but through the test program developed by DESSMANN, which is continuously aging under the condition that the test procedure of the circuit board is continuously running.
After learning about the production and testing process of several parts of the fingerprint lock, the reporter visited a well-equipped test workshop. In detail, there are more than 10 test items included in the test shop, mainly:
1. Electromagnetic vibration testing machine: It is used for the environmental adaptability experiment of vertical sine wave vibration of various mechanical parts and circuit components in the fingerprint lock.
2. High and low temperature alternating thermal test chamber: used to test the adaptability of fingerprint lock under high and low temperature and constant temperature. For example, the lowest temperature in the northern winter is minus 20°, and the humidity in Hainan Island is particularly large. Through the extreme testing of the equipment, the fingerprint lock can be safely used throughout the country.
3, salt spray test machine: used for zinc alloy, plastic and other materials after plating corrosion resistance test. According to Deschman's process standards, the neutral salt spray test time of its PVD plating products is more than 400 hours, and the relevant national standard is only 48 hours.
4, electrostatic discharge immunity test: used for fingerprint lock magnetic electrostatic discharge anti-interference test. The human body sometimes has a strong static electricity, and the electronic circuit board in the fingerprint lock is damaged by static electricity if the quality is not good. Deschman's electrostatic generators have a high voltage of 25,000 volts, which ensures that the fingerprint locks are used correctly.
5, button life tester: for fingerprint lock button endurance life test or continuity test.
6. Multi-functional wear-resisting test machine: used for testing the wear-resistant test of paint film parts and electroplated coated parts. Nowadays, many cheap locks begin to fade, electroplating and so on after half a year of use. Through the test of the instrument, it can be ensured that the lock is still bright after many years under normal use environment.
7. Lock body life tester: used for lock body life and aging test. The test equipment is also unique to Deschmann, and is independently developed from mechanical structure design, circuit board design, and test program writing.
8. Drop tester: used to simulate collisions that occur during transportation.
The above various tests fully guarantee that the lock products are used in the convenience and safety of various real estates after leaving the factory. The lock is an inseparable companion in people's daily life. It has an irreplaceable position. It carries the happiness of the family and is a symbol of safety. Through this visit, the reporter learned that the production of a high-quality fingerprint lock can be achieved through a series of complicated high-tech system engineering. The purchaser should consider the brand from many aspects such as manufacturer background, product appearance, technology application, quality certification, equipment guarantee and so on. In addition, a quality lock product also includes the responsibility of a good company in the face of the public. Only such high-quality enterprises that are professional and socially responsible can gain the respect and trust of more users and become the first choice of users, so that they can gain a place in the increasingly competitive market.
