Description

Technical Field

[0001] The invention relates to a smart card production device, in particular to a smart card issuing device. Background Art

[0002] In the production process of smart cards, the processing of cards is usually carried out in an assembly line manner. Specifically, in the production equipment of smart cards, a card issuing device usually sends the cards to be processed one by one to a card conveying line.

[0003] The existing card issuing device includes a card hopper, a card suction mechanism and a conveying mechanism. When working, the cards are first stacked in the card hopper, and then the card suction mechanism absorbs a single card and sends the card to the card conveying assembly line for subsequent card production and processing. This process is repeated to achieve the task of issuing cards one by one on the assembly line; for example, the utility model patent with authorization announcement number CN208013979U discloses a card issuing component of a card issuing machine.

[0004] The above-mentioned card issuing device has the following deficiencies in operation:

[0005] Since the cards are stacked vertically in the card hopper and the surface of the cards is smooth, there may be vacuum adsorption between two adjacent cards. In particular, the card at the bottom is subject to the greatest gravity and is most likely to be vacuum adsorbed with the card above. Then, when the suction cup sucks the cards downward, the cards may overlap, causing errors in card issuance and affecting subsequent processes. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems and provide a smart card issuing device, which can avoid the phenomenon of card overlap and ensure the smooth completion of the card issuing work.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A smart card issuing device comprises a card hopper, a card suction mechanism, a card lifting and clamping mechanism and a conveying mechanism;

[0009] The card hopper is provided with a card storage channel for stacking cards, and both sides of the bottom of the card storage channel are provided with supporting parts for supporting cards;

[0012] The working principle of the above-mentioned smart card issuing device is as follows:

[0013] During operation, a large number of cards to be issued are stacked in the card storage channel of the card hopper, and the cards at the bottom are placed on the supporting part of the card storage channel; the card lifting drive mechanism directly or indirectly drives the card clamping blocks of the two sets of card clamping and lifting assemblies to move in the corresponding direction, and under the guidance of the two sets of swing arms, the card clamping blocks are tilted and translated from bottom to top, close to the cards in the card storage channel, and then the bottoms of the inclined surfaces of the card clamping blocks of the two sets of card clamping and lifting assemblies are symmetrically clamped on the two side surfaces of several cards located below, and continue to move diagonally upward a slight distance, which is equivalent to squeezing and clamping the cards on both sides. At this time, the several cards are collectively bent (slightly elastically deformed, without affecting their own structure), and at the same time, gaps are generated between adjacent cards, thereby destroying the vacuum negative pressure state that may exist between the two, and preventing the cards from overlapping due to vacuum adsorption.

Under the action of the second movable transmission hole, the clamping block can translate close to the card and lift up the other cards except the bottom card, so that the second to last card below is separated from the bottom card to prevent the cards from overlapping.

[0020] Furthermore, the eccentric wheel outer fixed sleeve is provided with a first rolling bearing.
