Blood type detection card filling machine

Abstract

A blood type detection card filling machine comprises a rotary disc mechanism, an automatic card feeding structure, a liquid filling mechanism, a powder filling mechanism and a heat-seal mechanism, wherein the automatic card feeding structure, the liquid filling mechanism, the powder filling mechanism and the heat-seal mechanism serve as a filling and sealing mechanism. The rotary disc mechanism comprises a rotary disc, a photoelectric sensor, a rotary disc stepping motor and a clamping groove. The automatic card feeding mechanism, the liquid filling mechanism, the powder filling mechanism and the heat-seal mechanism are sequentially arranged around a rotary disc in a 90-degree spacing manner. The automatic card feeding mechanism comprises a card feeding stepping motor, card feeding guide rails, a card push air cylinder, a card push sliding block, a card push guide rail, a card containing card row, a card push initial position sensor, a locating blocking piece, a card push locating sensor, a card push finial point position sensor and a card push synchronizing belt. The liquid filling mechanism comprises a liquid filling support, a liquid filling motor, a liquid filling lead screw, a stroke switch, an upper needle plate, liquid filling syringe needles, a lower needle plate, needle holes and a liquid filling air cylinder. The powder filling mechanism comprises a powder filling support, a lifting air cylinder, a powder push air cylinder, a powder containing tank, a powder storage hole plate, a powder falling hole plate and a powder filling hopper. The heat-seal mechanism comprises a card feeding module, a heat-seal module and a paper feeding module.

Description

technical field [0001] The technical solution of the present invention relates to a plastic thin card filling machine, specifically a plastic thin card filling machine for blood type detection, that is, a blood type detection card filling machine. Background technique [0002] The micro-column gel blood type test card uses gel as the filler of the micro-column gel card, and utilizes the characteristic that only free red blood cells can pass through the gap between the gels, combining biochemical gel filtration technology, centrifugation technology and blood group serological antigen Antibody-specific responses are combined for use in blood group serology tests. The test card generally has 6 to 8 plastic microtubes side by side. Taking the ABO blood type test card with 6 plastic microtubes as an example, the first 3 plastic microtubes are filled with anti-A, anti-B and anti-A blood respectively. D antibody mixed with dextran gel in a certain proportion, used for positive det...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a filling machine for automatic production of blood type detection cards, which is based on controller control, driven by stepping motors and cylinders, driven by ball screws and synchronous belts, and realizes micro-filling. Precise powder filling, automatic film feeding, film cutting, and film sealing devices overcome the shortcomings of existing blood type cards such as low production efficiency, unstable product quality, high reject rate, slow production speed, and large human factors.
