Automatic needle sorting device

Abstract

The invention discloses an automatic needle sorting device. The automatic needle sorting device comprises a needle sorting die, at least one needle sorting mechanism arranged at the upper end of the needle sorting die, and a transmission mechanism which is arranged at the lower end of the needle sorting die and used for driving the needle sorting die to horizontally slide relative to the needle sorting mechanism; the upper end of the needle sorting die is provided with a plurality of needle slots used for containing needle bodies, the needle slots are arranged in parallel with a fixed distance, the horizontal planes of openings of the needle slots are arranged upwards, the bottoms of the needle slots are provided with one or multiple air holes, the needle sorting die is also provided with air channels corresponding to the needle slots, the air holes are communicated with the corresponding air channels which are independent; the needle sorting mechanism comprises a needle hopper used for containing needle bodies, a needle outlet is formed in the upper linear surface facing the needle sorting die, of the needle hopper; the needle bodies are automatically scraped to be separated from the needle hopper to fall into the needles slots of the needle sorting die; the needle sorting device has the advantages of high efficiency, good quality, less needed time and conservation of a large amount of labor force.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to blood collection needles, acupuncture needles, injection needles, indwelling needles and other cylindrical needle body separation applications, in particular to an automatic minute needle for separating needle bodies according to the required number device. Background technique [0002] At present, the cylindrical needle body in the medical field needs to be separated one by one and placed on the required assembly parts before injection molding and parts assembly. At present, the operation of placing the needles is done manually by the operator or by rolling the needle. The separation is completed, but the efficiency of manual needle placement is low, and due to the high labor intensity of manual needle placement, the operator needs to check the placement position of the needle body, the orientation of the needle tip, etc. when placing the needle. Long-term work will inevitably lea...

Problems solved by technology

[0002] At present, before injection molding and parts assembly of cylindrical needles in the medical field, the needles need to be separated one by one and placed on the required assembly parts. At present, the operation of placing the needles is done manually by the operator or by rolling the needle. The separation is completed, but the efficiency of manual needle placement is low, and due to the high labor intensity of manual needle placement, the operator needs to check the placement position of the needle body, the orientation of the needle tip, etc. when placing the needle. Long-term work will inevitably lead to the needle body not being placed in place. Misplacement, wrong orientation of the needle tip, etc.

The other type of needle roller type automatic separation needs to use servo to control the roller on the needle release side, which is slow in efficiency, and it is easy to place the needle crookedly or place it on another mold cavity when the roller is placed on the mold, which may cause needle shortage or double needles. , poor stability
