Description

Technical Field

[0001] This utility model relates to the field of smart card production technology, specifically to an anti-static clamping and protective fixture for smart card production. Background Technology

[0002] In the mass production process of smart cards, multiple continuous processing steps are involved, including chip packaging, surface printing, information writing, and quality inspection. Efficient transfer between these steps is a key factor in ensuring production efficiency. Currently, the industry commonly uses a transfer solution that combines conveyor belts with robotic arm gripping components. This involves using a conveyor belt to transport smart cards from upstream processes to a designated area, where a robotic arm drives the gripping components to grasp the cards and then transfer them to downstream processing stations. This solution has been widely adopted in automated production scenarios.

[0003] However, existing transport solutions have shortcomings in practical applications, directly leading to a decrease in smart card production yield. Conveyor belts primarily rely on friction to transport smart cards. During transport, the cards continuously contact and rub against the conveyor belt surface, easily generating and accumulating static electricity. Most existing robotic arm gripping components only have basic gripping functions and lack specific anti-static designs, failing to eliminate the static electricity accumulated on the card surface. Smart cards integrate sophisticated chip circuits and conductive lines, and these electronic components are extremely sensitive to static electricity. When the accumulated static electricity reaches a certain threshold, electrostatic discharge easily occurs when the gripping components contact the card, potentially breaking down the chip circuits or damaging the conductive lines, resulting in damage to the smart card.

[0027] Working Principle: The base block 1 serves as the load-bearing foundation for the entire fixture. Its conductive rigid structure not only provides stable support but also plays a crucial role in electrostatic conduction and release. The base block 1 is fixedly installed at the designated position on the existing robotic arm, ensuring reliable grounding, thus completing the equipment installation and positioning, laying the foundation for subsequent operations. The telescopic rod 2 is assembled in the guide hole within the base block 1. Its end facing away from the telescopic opening / closing assembly 3 is connected to the power mechanism (linear servo motor, electric servo telescopic rod, etc. are recommended). The power mechanism drives the telescopic rod 2 to perform precise telescopic movements along the guide hole, while the robotic arm moves the entire fixture to the smart card clamping area.

[0028] The telescopic rod connecting block 11 in this component is fixedly connected to the telescopic rod 2. When the telescopic rod 2 extends or retracts, it synchronously drives the telescopic rod connecting block 11 to move linearly. Since the two sets of T-shaped clamping blocks 9 are rotatably connected to the fixed shaft block 7 via the fixed shaft 8, and the axis of the fixed shaft 8 intersects and is perpendicular to the axis of the telescopic rod 2, and the two sets of T-shaped clamping blocks 9 are hinged to the telescopic rod connecting block 11 via the crank rod 10, a complete crank-hinged transmission structure is formed. When the telescopic rod connecting block 11 extends forward with the telescopic rod 2, it pulls the two sets of T-shaped clamping blocks 9 to rotate relative to each other around the fixed shaft 8 via the crank rod 10, causing the clamping ends of the two sets of T-shaped clamping blocks 9 to move closer together; conversely, when the telescopic rod 2 retracts, the crank rod 10 pushes the two sets of T-shaped clamping blocks 9 to rotate in opposite directions, causing the clamping ends to separate, thus accurately converting the linear extension and retraction motion of the telescopic rod 2 into the opening and closing clamping motion of the T-shaped clamping blocks 9. The fixed shaft block 7 and the connecting rod 6 are fixed on one side of the base block 1, providing stable installation support for the fixed shaft 8 and ensuring the motion accuracy of the transmission structure.

[0029] An anti-static chuck 4 is mounted on a T-shaped chuck block 9, and clamps and releases the smart card as the T-shaped chuck block 9 opens and closes. The quick-release metal base block 12 of the anti-static chuck 4 is detachably connected to the T-shaped chuck block 9 via bolts. The plastic clamping plate 13 is fixed to the quick-release metal base block 12 via a connector 14 and a connector 15, facilitating subsequent maintenance and component replacement. The flexible gasket 17 on the plastic clamping plate 13 is made of silicone rubber, which cushions the clamping force during clamping, preventing damage to the smart card. Simultaneously, an anti-static conductive block 5 is snapped into the conductive block fixing groove 16 of the plastic clamping plate 13, with one end in close contact with the side of the quick-release metal base block 12, and the other end protruding through the plastic clamping plate 13 and contacting the surface of the smart card. Because the quick-release metal base block 12 is connected to the T-shaped chuck block 9, and the telescopic opening / closing assembly 3 is made of conductive material and electrically connected to the base block 1, which is grounded, a complete electrostatic conduction path is formed. When the static electricity eliminator 5 contacts the smart card, the static electricity generated on the smart card surface due to friction from the conveyor belt is sequentially transferred through the static electricity eliminator 5, the quick-release metal base block 12, the T-shaped chuck block 9, and the telescopic opening and closing assembly 3 to the base block 1, and then released through the grounding device, completely preventing electrostatic discharge from damaging the precision electronic components inside the smart card. After clamping and static electricity elimination are completed, the robotic arm drives the fixture to transfer the smart card to the next processing station. The entire operation is efficient and safe, achieving integration of clamping, transfer, and anti-static protection.
