Abstract

The invention discloses an automatic assembling process for a centrifugal blood pump rotor and belongs to the technical field of assembling equipment. The automatic assembling process comprises a conveyor belt, a bearing magnetic pile press-fitting mechanism, a motor magnet mounting mechanism and a base mounting mechanism. A plurality of limiting assemblies are arranged on the conveyor belt. The motor magnet mounting mechanism comprises a sliding plate, a worktable, a pushing assembly, a lifting assembly, a clamping assembly and a bearing frame. The clamping assembly comprises a mounting plate, a four-jaw air cylinder and a limiting column arranged at the bottom of the mounting plate. A limiting plate is mounted at the bottom of each clamping jaw of the four-jaw air cylinder. An arc-shapedgroove is formed in the limiting plate. Four bearing rods are arranged between the mounting plate and the sliding plate. According to the automatic assembling process, steps of press-fitting bearingmagnetic piles, mounting motor magnets and a base for the centrifugal blood pump rotor can be finished automatically. Four motor magnets can be mounted in an impeller simultaneously by the motor magnet mounting mechanism, and it is not needed to mount the motor magnets one by one by a worker.

Description

technical field [0001] The invention relates to the technical field of processing technology for medical device accessories, in particular to an automatic assembly technology for centrifugal blood pump rotors. Background technique [0002] In cardiovascular medicine, the clinical use of artificial hearts (or blood pumps) as a bridge to heart transplantation or as a form of terminal therapy to support patients with advanced heart disease has become accepted clinical practice. The number of patients who suffer from heart disease and need heart replacement surgery is very large, but the serious shortage of transplant donors makes it difficult for most heart disease patients to treat and even lose the chance of survival. Therefore, it is of great significance to develop a high-performance heart pump. [0003] A ventricular assist device can use a blood pump to power the patient's blood, which pushes the blood to high pressure. One example of a ventricular assist device is a le...
