Production process of disposable blood lancet and device thereof

Abstract

The invention provides a production process of disposable blood lancet and device thereof, the production process comprises needle-arranging, impact-bending formation, needle-transferring, and injection molding, the specific step is as follows: 1) piling up naked processed blood lancet in a needle arrangement, wherein a magnetic needle-arranging support module passes through the bottom of the needle arrangement, the naked blood lancets are arranged on the magnetic needle-arranging support module; 2) impact-bending formation, wherein the magnetic needle-arranging support module is sent into a punch press through a positioning chute, a male module punch head on the punch press executes the bending formation to the naked blood lancets arranged on the magnetic needle-arranging support module;3) needle-transferring, wherein the magnetic needle-arranging support module is removed from the punch press along the positioning chute, manual or mechanical hand can pick up the entire row of nakedblood lancets on the magnetic needle-arranging support module by using a magnetic needle transferring machine, then the entire row of naked blood lancets is arranged on the injection module; 4) injection molding, wherein the injection module is compounded to perform injection molding, then the module is opened to manufacture the semi-finished product of the blood lancet, the finished product can be obtained by shearing, deburring and packaging the semi-finished product.

Description

technical field [0001] The invention relates to the technical field of medical device processing, in particular to a production process and equipment for a disposable blood collection needle. Background technique [0002] Blood collection needles are used in the process of blood collection and testing in hospitals or at home. The structure of the blood collection needle is that the blood collection needle is made of steel wire and is set in a plastic handle through an injection molding process. The front part of the plastic handle is provided with a needle that can be disconnected. Caps, the current production process is in the injection molding process, first of all, the steel wires processed with needlepoints are manually arranged on the molding mold, and the steel wires are transferred to the injection mold after molding, and then the injection molding machine injects plastic into the mold, and it is ready after demoulding. As blood collection needles used in hospitals, s...

[0002] Blood collection needles are used in the process of blood collection and testing in hospitals or at home. The structure of the blood collection needle is that the blood collection needle is made of steel wire and is set in a plastic handle through an injection molding process. The front part of the plastic handle is provided with a needle that can be disconnected. Caps, the current production process is in the injection molding process, first of all, the steel wires processed with needlepoints are manually arranged on the molding mold, and the steel wires are transferred to the injection mold after molding, and then the injection molding machine injects plastic into the mold, and it is ready after demoulding. As blood collection needles used in hospitals, since the steel wires of uninjected blood collection needles are thin, light and small, it is very difficult to transfer from the forming mold to the injection mold. In the prior art, manual transfer of the needles one by one is very labor-intensive. Moreover, the efficacy is very low, and it is easy to drop and miss stitches, resulting in a large amount of waste products. After the missing stitches occur, they must be manually picked out from the product one by one, which not only takes up a lot of labor, but also is very troublesome. At present, there is no good one.
