Description
Technical Field
The invention relates to smart card manufacturing equipment, in particular to a smart card chip overturning and wire gathering device.
Background
In the production of smart cards, it is necessary to package the chip into the card. The packaging technology of the chip sequentially comprises slot milling, thread picking, butt welding, packaging and the like, wherein two antennas extending out of a chip slot of the card are in a vertical state during butt welding, and the chip to be welded is connected with the antennas in a vertical state; before the subsequent packaging, the bumped chips in the erected state need to be turned to a horizontal state so that the chips can be aligned with the chip grooves, and the chips can be pressed into the chip grooves in the subsequent packaging process; in addition, before packaging, besides the chip needs to be turned to be in a horizontal state, the antenna in a vertical state is also pre-bent (called as a 'line gathering' in the invention), so that the antenna can be folded and gathered in a chip groove during packaging.
In the existing production process, the work of chip overturning and wire gathering is respectively completed by a chip overturning mechanism and an antenna wire gathering mechanism.
The existing chip turnover mechanism mainly comprises a group of antenna bending mechanisms which move relatively, the two antenna bending mechanisms are staggered in the height direction, and when the chip turnover mechanism works, the two antenna bending mechanisms move in opposite directions and act on the two erected antennas respectively, so that the antennas bend in opposite directions at two action points, and the erected chip is converted into a horizontal state.
The two antenna bending mechanisms bend the antenna to be packaged into a horizontal state along the direction perpendicular to the connecting line direction of the antenna, the antenna is not gathered inwards, so that the antenna can not be completely pressed into a chip slot by the chip when the chip is packaged, the antenna in the bending state along the direction parallel to the connecting line direction of the antenna is also subjected to pre-bending (called as a gathering line in the invention), the existing antenna gathering mechanism consists of two pushing pieces and a driving mechanism pushing the two pushing pieces to move oppositely, the two pushing pieces are positioned at two sides of the two antennas (specifically at two sides of the connecting line direction of the two antennas, the connecting line direction of the two antennas is called as a gathering line direction) when the antenna is gathered, the driving mechanism synchronously pushes the two pushing pieces to move relatively along the gathering line direction, the two pushing pieces act on a certain part of the height direction of the antenna, the part of the two antennas is gathered towards the middle to enable the two antennas to bend to a certain extent, and then the two antennas can be folded along the bending part in the following packaging process, so that the chip can be pressed into the chip completely.
In the existing antenna line gathering mechanism, the line gathering direction is consistent with the arrangement direction of the antenna and also consistent with the conveying direction of the card in the card conveying guide rail, so that when the card is fed into the line gathering station, the pushing piece needs to avoid the antenna and the chip, the antenna line gathering mechanism also needs to be provided with a vertical driving mechanism for pushing the pushing piece to do vertical reciprocating motion, the vertical driving mechanism drives the pushing piece to move downwards when the line is gathered, and after the line is gathered, the vertical driving mechanism drives the pushing piece to reset upwards.
The existing intelligent card chip turnover mechanism and wire gathering mechanism have the following defects:
1. the existing chip turnover mechanism indirectly realizes the turnover of the chip through the bent antenna, the levelness of the turned chip is difficult to ensure, and the position relationship between the turned chip and the chip slot is also difficult to ensure (the chip cannot be accurately aligned with the chip slot), thereby influencing the subsequent packaging processing.
2. The existing antenna wire gathering mechanism has the defects that the pushing and pressing piece needs to do relative wire gathering actions in the working process and also needs to do vertical reciprocating motion frequently, so that the wire gathering time of a single card is long, and the efficiency is low.
3. The structure is complex, the volume is large, and the cost is high.

After the wire gathering work is completed, the vacuum suction head of the chip in-situ overturning mechanism overturns, the vacuum suction head loosens the overturned chip, then the linear driving mechanism drives the middle connecting seat and the overturning executing mechanism on the middle connecting seat to reset, and simultaneously, the telescopic rod of the telescopic cylinder retracts to enable the suction surface of the vacuum suction head to recover to a standing state, and the intelligent card chip overturning and wire gathering device waits for the next chip in-situ overturning and wire gathering work.
