example 1

[0022] Example 1, a high-reliability blood type card grabbing manipulator, including a seat plate 1, a sliding sleeve 2, a swing claw 11, and a stepping motor 3, the stepping motor 3 is installed on the seat plate 1, and the The motor shaft of the stepping motor 3 is a threaded shaft, the sliding sleeve 2 has an internal thread matched with the threaded shaft and an external guide structure matched with the seat plate 1, and the upper part of the swing claw 11 is connected to the The first pin shaft 9 is hinged, and the middle part is hinged with the seat plate 1 through the second pin shaft 12; it is characterized in that it also includes a guiding device, and the said guiding device includes a small hole arranged in the two stepped holes in the seat body 1. Two linear bearings 8, two three-stage stepped guide shafts 7 with the largest middle diameter; Spring 6 and spring gland 5 are sleeved on the upper section of the upper section, and the upper end of the guide shaft passe...

example 2

[0024] Example 2, other is the same as Example 1, the difference is that the lower end of the sliding sleeve 2 is provided with a through hole that reaches the pin hole matched with the first pin shaft 9, and a rubber rubber abutting against the first pin shaft 9 is arranged in the through hole. The spring 13, the rubber spring 13 is encapsulated by the cover plate 14. In this way, the sliding sleeve 2 is in contact with the swing claw 11 and adopts a soft contact, and the rubber spring 13 below the first bearing pin 9 is used. The hole of the first pin shaft 9 on the sliding sleeve 2 is a long hole, the first pin shaft 9 can move up and down a small amount, and a rubber spring 13 is housed in the through hole at the lower end, and is preloaded under the first pin shaft 9, When the sliding sleeve 2 moves up to grab the blood type card, the first pin shaft 9 is subjected to the downward force of the swing claw 11, and due to the action of the rubber spring 13, the swing claw 11...

example 3

[0025] Example 3, other is the same as embodiment 2, the difference is that the output shaft of stepper motor 17 is connected with encoder 18. The encoder, stepper motor and control system constitute a closed-loop control system. Encoder 18 is used as the actual deflection angle of the feedback motor rotation angle. Correct and detect the position of the swing claw from time to time to prevent the stepping motor from losing steps and causing the card to be loose or not to be grasped.

Abstract

The invention discloses a high-reliability type blood type card grabbing manipulator which is characterized in that the high-reliability type blood type card grabbing manipulator comprises a pilot device; the pilot device comprises two linear bearings arranged in small holes of two step holes in a seat body, and two three-section step type guiding axles; the middle parts of the guiding axles are maximum; the lower sections of the guiding axles are arranged in the linear bearings in a penetrating manner; the middle sections of the guiding axles are arranged in large holes of the step holes; springs and spring pressing covers are arranged at the upper sections of the guiding axles in a sleeving manner; the upper ends of the guiding axles penetrate through the spring pressing covers and then are related to a sensor; the lower ends of the guiding axles are fixedly connected with a pilot plate body; guiding bosses are formed below the pilot plate body; when a blood type card is located at a position of a centrifuge, the blood type card can rotate around a fixed shaft in a clamp sleeve along with the clamp sleeve within a small range. According to the high-reliability type blood type card grabbing manipulator, the blood type card is located and then grabbed, and the blood type card is flattened and then grabbed, so that the correct state of the blood type card after being grabbed from the centrifuge is ensured.

Description

technical field [0001] The invention belongs to the medical device industry, in particular to a manipulator used for grabbing blood type cards. Background technique [0002] Card type microcolumn gel method for blood type identification is currently the most commonly used detection method for blood type detection. It automates blood type detection, not only improves the efficiency, but more importantly, improves the accuracy of blood type detection. Immuno-column gel detection method is currently the most advanced detection method in the field of serology. Compared with the traditional slide method and test tube method, it has the advantages of high sensitivity, easy standardization, and long-term storage of reagent cards at room temperature. For the blood type automatic detection instrument used in the immunocolumn gel detection method, it needs to solve a series of functions such as punching, adding samples, incubation, centrifugation, and interpretation, which are all fun...
