[Text/High-tech LED Xu Chaopeng] In 2016, it was an important year for Huajie to implement the strategy of “transmutation and leapfroggingâ€. In order to promote the rapid improvement of product quality, seize the highest point of market competition and improve customer satisfaction, Huajie Optoelectronics Co., Ltd. The R&D center, quality assurance center and production center jointly launched a comprehensive and in-depth quality improvement management action.
It is understood that in the comprehensive quality management activities, Huajie pays attention to the actual needs of customers, through thorough market research, rapid research and development, production, inspection and transportation, shortening the response time to customer demand and improving the quality of service.

"In this process, we specifically analyzed the various quality links of production, and insisted on the meticulousization of various tasks through dataization. Through the real-time data collection and analysis of production lines, many effective quality improvement measures were developed. Li Haojin, director of Huajie Optoelectronics R&D Center, said.
The implementation of this quality management action also includes four major measures:
Measure 1: All members participate in quality management, comprehensive training and promotion. Relying on the company's powerful comprehensive training system, Huajie has carried out comprehensive and systematic quality management training for all levels of employees at the production base, so that all production personnel firmly established the idea of ​​“quality first†and “customer firstâ€. Used in actual production activities.

Measure 2: Analyze the quality loop, clarify the quality functions of each link, and set up key process inspection contents and standards. 1. Plug-in process: check lamp polarity, high and low lamp, twist lamp, colloid color, lamp multi-glue, less glue and insert in place; 2. Wave soldering process: the process department is separated by 1 hour to the furnace temperature, tin volume and Flux is tested. The quality control department conducts random inspection and recording of the lamp panel every hour; 3. Test procedure: record the products tested, the quality assurance center summarizes the daily maintenance report; 4. The glue filling process: the glue ratio is strictly required. Sampling inspection of the finished glue filling at intervals of 40 minutes; 5, before the aging on the finished product, it is necessary to strictly carry out sampling inspection according to the general level III of GB2828-2003.
Measure 3: Study the specific organizational structure, combine the production line and automatic assembly line mode, and set up relevant inspection posts, and regularly test and maintain the production equipment such as placement machine, reflow soldering, plug-in machine, wave soldering, automatic spraying machine, etc. The normal operation of each production equipment, thereby improving the stability of product quality. At the same time, the company also organized regular mutual inspections of various positions in production to prevent omissions.
Measure 4: Establish a sound system of accountability and quality assurance. Data analysis and tracking of product quality were performed by mathematical statistics to observe the steady state of the production process. Analyze the factors that affect the quality of the product, and carry out quality control and improvement at each stage.

"By all employees' operations, and multiple measures simultaneously, Huajie has achieved remarkable improvement and optimization in product quality. The pass rate of raw materials is up to 99.9%, the product qualification rate is over 98%, and the qualified rate of shipment products is up to 99.9. With the rapid improvement of product quality, the employees' superior product awareness, production skills and quality management skills have been significantly improved. It has laid a solid foundation for the long-term development of the company." Li Haojin said.
“All in all, quality is the lifeline of an enterprise, an important pillar for improving the competitiveness of a company, and a fundamental guarantee for the prosperity and development of a company. In the future, we will certainly create more sophisticated products to give back to the trust of our customers. Dancing miracles, you will navigate the future!†Li Yihua, chairman of Huajie Optoelectronics, finally mentioned.
A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.
DC motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools and appliances. Larger DC motors are used in propulsion of electric vehicles, elevator and hoists, or in drives for steel rolling mills.
Dc motor areas of application: smart home field, robotics, precision medical equipment industry, automotive drive field, electronic products and personal care equipment
Application of the product:
Features: high torque, low noise, small volume, light weight, easy to use, running constant speed, etc., can also be matched with various gearboxes to change the output speed and torque.
Features: small volume, fast speed, stable performance, low price, good speed regulation.
Method of use: the best stable in horizontal plane, installed on the dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
DC motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
DC motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of DC motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
