Card pulling mechanism for smart card

Abstract

The invention discloses a card pulling mechanism for a smart card. The card pulling mechanism for the smart card comprises a card pulling synchronous belt and a power mechanism, wherein the card pulling synchronous belt comprises a synchronous belt body and pulling teeth, and the power mechanism comprises a synchronous wheel and a servo motor; synchronous teeth are arranged at both of the inner side and the outer side of the synchronous belt body, and gaps among the synchronous teeth form synchronous tooth grooves; the pulling teeth are arranged at the outer side of the synchronous belt body, and the bottoms of the pulling teeth are embedded in the synchronous tooth grooves in the outer side of the synchronous belt body; screws for fixing the pulling teeth onto the synchronous belt body are arranged on the synchronous teeth corresponding to the pulling teeth, in the inner side of the synchronous belt body; and synchronous teeth matched with the synchronous tooth grooves in the inner side of the synchronous belt body are arranged on the excircle surface of the synchronous wheel, and the synchronous teeth are configured to be annular clearance grooves at positions corresponding to the screws. According to the card pulling mechanism for the smart card, which is disclosed by the invention, the pulling teeth can be fixed at the outer side of the synchronous belt body through the screws from the inner side of the synchronous belt body; and moreover, the advantages that the positions of the pulling teeth can be flexibly changed, the rigidity of the pulling teeth is high, the connection between the pulling teeth and the synchronous belt body is firm, and the like, are achieved.

Description

technical field [0001] The invention relates to smart card production equipment, in particular to a smart card dialing mechanism. Background technique [0002] In the production line of smart cards, the cards need to be conveyed by the card conveying mechanism. Common card conveying mechanisms include synchronous belt dial mechanism, roller conveying mechanism, etc. Among them, the synchronous belt dial mechanism is widely used due to its advantages of high stop accuracy, long conveying stroke, and equidistant conveying. The synchronous belt dial mechanism is mainly composed of a dial synchronous belt and a power mechanism, wherein the dial synchronous belt includes a synchronous belt body and a shifting tooth arranged on the synchronous belt body, and the shifting teeth are equidistantly arranged on the synchronous belt body. Used to move the card, the power mechanism includes a synchronous pulley and a servo motor. In the existing synchronous belt dial mechanism, the shi...

AI Technical Summary

Problems solved by technology

[0003] 1. The shifting teeth and the timing belt body are integrally formed or glued together, and the position cannot be changed after forming, so that the distance between the shifting teeth cannot be adjusted as required, and the versatility is poor

[0004] 2. The shifting gear is made of plastic, which has poor rigidity and wear resistance, and is prone to deformation and wear during work, thus affecting the positioning accuracy of the card

[0005] 3. The connection between the shifting teeth and the timing belt body is not strong enough, and it is prone to breakage after a long time of work

[0006] 4. Since the shifting teeth are arranged between the two ends in the width direction of the synchronous belt body, the card dialing synchronous belt must be installed below the card conveying track of the smart card production equipment. For other mechanisms and components, the space of this part is small, which brings difficulties to the installation, debugging and maintenance of the dial timing belt, and also limits the size of the dial timing belt
