Description

Technical Field

[0001] This utility model relates to the field of card storage production and processing technology, specifically a gripper device for removing cards from a card slot. Background Technology

[0002] In many automated systems involving card processing today, such as financial self-service machines, smart card management systems, and document card archiving devices, accurately and efficiently retrieving cards from the card slot is a key operational step. Traditional gripper devices generally use mechanical structures to control the opening and closing of the gripper, and use motors or pneumatic devices to drive the gripper to achieve the clamping and releasing action to complete the card grabbing.

[0003] However, such traditional gripper devices have significant drawbacks. On the one hand, to ensure the cards are gripped securely and prevent slippage, considerable power is often required during the gripping process. This can easily lead to excessive compression and damage to the cards, especially for precision cards with special surface coatings or built-in chips, where the risk of damage is extremely high. On the other hand, when gripping cards, the opening and position of the gripper must be precisely controlled. If the cards in the card slot are not aligned or are slightly deformed, the gripper cannot accurately adapt, easily resulting in gripping failures or paper jams caused by gripping multiple cards simultaneously. This greatly affects the stability and efficiency of system operation, increasing maintenance costs and time consumption.

[0004] Furthermore, traditional gripper devices have complex mechanical structures involving numerous parts and intricate transmission links, resulting in bulky and expensive equipment. Frequent mechanical movements can also cause wear and tear on components, reducing the lifespan and reliability of the equipment and failing to meet the demands of modern, efficient, precise, and stable card processing. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gripper device for removing cards from a card slot, which solves the problems of cards being easily damaged by excessive squeezing during card gripping, difficulty in precise positioning, easy gripping failure or paper jam caused by gripping multiple cards at the same time, low efficiency and high maintenance costs.

[0006] This utility model provides a gripper device for removing cards from a card slot. It is characterized by comprising a robotic arm, an upper gripper block, a tensioning spring, and a lower gripper block. The upper gripper block is fixedly disposed at the end of the robotic arm, and the lower gripper block is rotatably disposed at the end of the robotic arm and located below the upper gripper block. One end of the tensioning spring is fixedly connected to the lower gripper block, and the other end of the tensioning spring is fixedly disposed at the end of the robotic arm or on the upper gripper block. The front ends of the upper and lower gripper blocks are provided with wedge-shaped structures for guidance. The tensioning spring maintains a normal clamping state between the upper and lower gripper blocks.

[0007] In a preferred embodiment, a card gripping surface is provided between the front ends of the upper gripping block and the lower gripping block, and the card gripping surface is provided with anti-slip texture.

[0008] In a preferred embodiment, multiple steps are provided between the upper and lower gripping blocks and on the rear side of the card gripping surface, and the steps on the upper and lower gripping blocks fit together.

[0009] In a preferred embodiment, the length of the card-grabbing surface is less than the length of the card to be gripped.

[0010] In a preferred embodiment, the upper front part of the upper clamping block and the lower rear part of the lower clamping block are respectively provided with folded surfaces, and a clamping groove is provided between the folded surfaces of the upper clamping block and the lower clamping block, and the tightening spring is embedded in the clamping groove.

[0011] In a preferred embodiment, two tensioning springs are provided and symmetrically arranged inside the clamping groove.

[0012] In a preferred embodiment, the two ends of the tensioning spring are fixed by screws.

[0013] In a preferred embodiment, a base is fixedly mounted on the bottom of the robotic arm.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Card protection: Through reasonable design, it avoids damage to cards caused by excessive pressure due to excessive force in traditional devices, and can especially reduce the risk of damage to precision cards with special surface coatings or built-in chips.

[0016] Precise Adaptive Grip: The front wedge structure has a guiding and buffering function. The steps between the front ends of the upper and lower gripper blocks fit together. The wedge structure with guiding function at the front ends of the upper and lower gripper blocks helps to accurately adapt and position, reducing gripping failures caused by misaligned cards in the card slot or slight card deformation, or paper jams caused by gripping multiple cards at the same time. This improves the stability and efficiency of system operation and reduces maintenance costs and time loss.

[0017] Structural optimization: The overall structure is simpler than traditional devices, reducing parts and complex transmission links, making the equipment smaller and cheaper. It also reduces wear and tear and failures caused by frequent mechanical movements, improving the service life and reliability of the equipment, and meeting the modern needs for efficient, accurate and stable card processing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown

[0024] A gripper device for removing cards from a card slot includes a robotic arm 1, an upper gripper block 2, a tensioning spring 3, and a lower gripper block 4. The robotic arm 1, serving as the power and support structure of the entire device, is made of high-strength, lightweight alloy material and possesses multi-degree-of-freedom motion capabilities, enabling precise positioning to the card slot. The upper gripper block 2 is fixedly mounted at the end of the robotic arm 1. The lower gripper block 4 is rotatably mounted at the end of the robotic arm 1 and located below the upper gripper block 2, ensuring that the lower gripper block 4 can rotate flexibly to open and close the gripper jaws. One end of the tensioning spring 3 is fixedly connected to the lower gripper block 4, and the other end is fixedly mounted at the end of the robotic arm 1. This fixing method allows the tensioning spring 3 to provide a stable clamping force to the lower gripper block 4. The front ends of the upper gripper block 2 and the lower gripper block 4 are provided with guide wedge structures 5. The angle of the wedge structure 5 guides the card 11 smoothly into the gripper device and provides a certain degree of cushioning, reducing the impact force when the card 11 enters. The tightening spring 3 keeps the upper gripper block 2 and the lower gripper block 4 in a normal clamping state. This design allows the gripper to maintain a certain clamping force even when no gripping action is performed, which facilitates the quick gripping of the card 11 later.

[0025] A card gripping surface 6 is provided between the front ends of the upper gripper block 2 and the lower gripper block 4. This gripping surface 6 is the part that directly contacts the card 11, and its surface quality directly affects the gripping effect. The card gripping surface 6 is provided with anti-slip texture, which can effectively increase the friction between the card and the card 11, prevent the card 11 from slipping during the gripping process, and improve the gripping success rate.

[0026] Multiple steps 7 are provided between the upper gripper block 2 and the lower gripper block 4, located behind the card gripping surface 6. The steps 7 are designed in a staggered arrangement, with the steps 7 on the upper gripper block 2 and the lower gripper block 4 fitting together. This improves the stability of the cooperation between the upper gripper block 2 and the lower gripper block 4. At the same time, the front end of the step 7 can play a positioning role. When gripping the card 11, the inner side of the card 11 can be blocked by the front end of the step 7, so the card 11 will not be completely inserted between the upper gripper block 2 and the lower gripper block 4, making it easier to remove the card 11.

[0027] The length of the card gripping surface 6 is less than the length of the card 11 to be gripped. This design takes into account the size difference of the card 11 and the stability of gripping. If the gripping surface 6 is too long, the card 11 may be completely inserted between the gripping surfaces 6 of the upper gripper block 2 and the lower gripper block 4, which is not conducive to the removal of the card 11.

[0028] The upper front part of the upper gripper block 2 and the lower rear part of the lower gripper block 4 are respectively provided with folded surfaces. A clamping groove 8 is provided between the folded surfaces of the upper gripper block 2 and the lower gripper block 4. The tightening spring 3 is embedded in the clamping groove 8. This design makes the spring installation more stable and less prone to displacement or falling off. At the same time, it reduces the space occupied by the spring and makes the entire gripper device structure more compact.

[0029] Two tensioning springs 3 are provided and symmetrically arranged inside the clamping groove 8. The symmetrical arrangement can make the rebound force on the upper clamping block 2 and the lower clamping block 4 more uniform, ensuring that the clamping hand can maintain a stable clamping force when clamping the card 11, and avoiding the clamping hand from tilting or being damaged due to excessive force on one side.

[0030] The two ends of the tension spring 3 are fixed by screws 10. The screws 10 are made of high-strength stainless steel and can withstand the tension when the tension spring 3 extends and retracts, ensuring that the tension spring 3 is firmly fixed. In later maintenance, the screws 10 are easy to remove and install, making it convenient to replace or repair the tension spring 3.

[0031] The bottom of the robotic arm 1 is fixedly equipped with a base 9. The base 9 has sufficient weight and stability to provide a solid support for the robotic arm 1.

[0032] When this utility model picks up card 11, the center of the gripper with elastic clamping force is aligned with the center of card 11, and the mechanical arm 1 is used to push forward to squeeze card 11 into the gripper. When the mechanical arm retracts, card 11 will be pulled out of the gripper under the clamping force.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
