Automatic biochemical analyzer is the clinical and biochemical analysis of sampling, adding reagent, the interference, mixing, heat preservation, detection, data processing, display and output as a result, as well as cleaning the experimental manipulation steps such as automation control equipment. Automatic biochemical analyzer, automatic sampling, sampling function is implemented by its sample system. Of mechanical actuators in sample system generally includes: cantilever mechanism and driving mechanism. Domestic current drive mechanism usually use rotary stepper motor and drive mechanism, such as: synchronous belt, gear and rack, such as ball screw; Transmission mechanism are connected to the cantilever mechanism, so as to realize automatic sampling function. Ball screw defect is big volume, high capital, high requirement to the institutional set-up, and ball screw pitch is larger, general agency resolution is not high. But the drawback is that of the other drive accuracy is not high, and the noise is bigger, the key is there is no guarantee that life, thus affecting the overall quality and grade of the products, and similar foreign products of the competition at a disadvantage. Due to the linear stepper motor internal implementation converting rotary motion to linear motion, make the cantilever mechanism and motor connected directly, while do agency elaborate as far as possible concise, without intermediate transmission link enables it to achieve higher accuracy of the machine, higher efficiency and more advanced age. Cleaner: linear stepper motor on the structure characteristics of brought it on the use of convenience. Linear stepper motor is, in fact, have such a successful application in the field of automatic biochemical analysis, because of its concise, accurate, sensitive perfect fit the characteristics of high reliability of automatic biochemical analyzer of linear motion control performance requirements. Higher precision: linear stepper motor adopts Acme screw drive, a screw rolling molding, the transmission accuracy can be 0. 0005 mm/mm, the highest resolution can reach 0. 0015mm。 In addition to reach higher accuracy, can deserve to go up reverse anti-backlash nut, it can eliminate the back lash, achieve higher precision of transmission. Higher efficiency, and gear rack transmission or synchronous belt transmission is commonly used in automatic biochemical analyzer, compared to the transmission mechanism of linear stepper motor has obviously higher transmission efficiency. The first is its Acme screw compared with general V thread, the tooth profile Angle of 29 degrees higher efficiency, and because it is specially designed for transmission, so the precision and surface finish, pitch of tolerance are not V thread can be compared. More advanced age life: because as the structural design of linear stepper motor patent (The patent number ZL200330102644 in China. 4 and 6 in the United States. 932319). , as well as professional linear transmission manufacturing process to ensure the overall organization of advanced age, in addition its self-lubricating materials and the quality of the screw nut processing, also with advanced age life assurance. In fact, under the condition of normal load, motor can reach at least 5 million times the cycle of life. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
