Description

Technical Field

[0001] This utility model relates to the field of electrical automation design, and in particular to a smart card adaptive pressing device. Background Technology

[0002] In today's digital age, smart cards are widely used, covering financial transactions, identity recognition, and access control. With the continued rapid growth in demand for smart cards and the increasing diversification and complexity of application scenarios, a smart card adaptive pressing device is needed for the manufacturing process of smart cards.

[0003] A search revealed Chinese patent publication number CN220829718U, which discloses a smart card adaptive pressing device. The device includes a linear track on a vertical positioning plate, a top positioning plate fixedly mounted on the top of the vertical positioning plate, a pressing path positioning post fixedly connected to the top positioning plate and parallel to it, an upper positioning plate sleeved on the pressing path positioning post and connected to the top positioning plate via adjusting bolts, a lower positioning plate sleeved on the pressing path positioning post and connected to the upper positioning plate via a pressing spring, a cylinder connected to the lower positioning plate, a pressing head mounting seat located above the lower positioning plate, the pressing head mounting seat slidingly engaging with the linear track, and the pressing head mounted on the pressing head mounting seat. A mounting groove is formed on the card base carrier plate, and an adaptive small platform is set in the mounting groove. The smart card to be pressed is placed on the adaptive small platform. This application claims good pressing effect, improving the quality stability and production efficiency of smart cards. However, existing smart card pressing devices suffer from poor pressing effect and unreliable finished product qualification rate. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a smart card adaptive pressing device, which aims to improve the problem of poor pressing effect and inability to guarantee the qualified rate of finished products in the existing smart card pressing devices.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a smart card adaptive pressing device, comprising a base, with connecting columns two fixedly connected to the top left and right sides of the base, and fixing plates fixedly connected to adjacent sides of the top of the two connecting columns two. A hydraulic cylinder is fixedly connected to the top of the fixing plate, and the output end of the hydraulic cylinder passes through the top of the fixing plate and is fixedly connected to a hydraulic plate. Connecting rods are rotatably connected to the front and rear sides of the outer wall of the fixing plate, and the other end of the connecting rods is rotatably connected to the front and rear sides of the top of the hydraulic plate. Pressing blocks are fixedly connected to the front and rear sides of the bottom of the hydraulic plate. Multiple springs are fixedly connected to the outer walls of the two pressing blocks, and buffer blocks are fixedly connected to the other ends of the multiple springs. Multiple connecting columns are fixedly connected to the bottom of the hydraulic plate, and springs are provided on the outer walls of the multiple connecting columns. Push plates are fixed to the other ends of the multiple springs. A placement plate is provided at the top center of the base, and multiple connecting cylinders are fixedly connected to the top of the placement plate. Pressure plates are fixedly connected to the inner walls of the multiple connecting cylinders. An alarm light is fixedly connected to the right side of the outer wall of the right connecting column. An adjustment mechanism is provided at the bottom of the base.

[0006] The above technical solution involves a hydraulic cylinder mounted on the top of a fixed plate. This hydraulic cylinder, a key component providing the pressing power, has its output end penetrating the top of the fixed plate and fixedly connected to the hydraulic plate. Connecting rods are located on the front and rear sides of the outer wall of the fixed plate. One end of each connecting rod is rotatably connected to the fixed plate, and the other end is rotatably connected to the front and rear top of the hydraulic plate. This allows the hydraulic cylinder to smoothly move the hydraulic plate up and down via the connecting rods when it extends and retracts, thus transmitting the pressing action. Pressing blocks are fixedly connected to the front and rear bottom of the hydraulic plate; these blocks are the components that directly contact the smart card for the pressing operation. Multiple springs are fixedly connected around the outer wall of the pressing block. The other end of each spring is connected to a buffer block. During the pressing process, when the pressing block comes into contact with the object being pressed, such as a smart card, the buffer block contacts it first and the springs work together to provide a buffering effect, preventing damage to the smart card from excessive pressure and making the pressing process smoother and gentler. Multiple connecting columns are also fixedly connected around the bottom of the hydraulic plate. Springs are installed on the outer wall of the connecting columns. A push plate is fixed to the other end of each spring. During pressing, the push plate will press down with the pressing action, and the springs can further provide a buffering effect and help adjust the pressure distribution throughout the pressing process.

[0007] As a further description of the above technical solution:

[0008] The adjustment mechanism includes two connecting plates. The tops of the two connecting plates are fixedly connected to the bottom left and right sides of the base. The bottoms of the two connecting plates are rotatably connected to support rods. The bottoms of the two support rods are slidably connected to support plates. A horizontal plate is fixedly connected to an adjacent side of the two support plates. A telescopic rod is fixedly connected to the top of the horizontal plate. The top of the telescopic rod is fixedly connected to the middle of the bottom of the base.

[0009] The above technical solution achieves precise adjustment of the device's height and horizontal position by sliding the bottom of two support rods to the support plate. When the device height needs adjustment, the vertical distance of the entire device relative to the support plane can be changed by altering the sliding position of the support rods on the support plate.

[0010] The horizontal plate is fixed to the adjacent side of the two support plates, serving to connect and reinforce them, ensuring that the two support plates can move synchronously and maintain the stability of the entire adjustment mechanism. The telescopic rod at the top of the horizontal plate is one of the key actuators for adjusting the height of the device, and the top of the telescopic rod is fixedly connected to the middle of the bottom of the base.

[0011] As a further description of the above technical solution:

[0012] The base has a connecting groove at the top center. Connecting cylinders are fixedly connected to the left and right sides of the inner walls of the two connecting grooves. Screws are threaded to the top of the two connecting cylinders. The outer walls of the two connecting cylinders engage with the placement plate.

[0013] The above technical solution provides positioning space for the placement plate through the connecting groove in the center of the base top, ensuring the plate is accurately positioned on the base and guaranteeing its stability during the pressing process. This prevents displacement deviations that could affect the smart card pressing effect. The connecting cylinders fixed to the left and right sides of the connecting groove further enhance the stability of the connection between the placement plate and the base.

[0014] As a further description of the above technical solution:

[0015] Multiple connecting pieces are fixedly connected to the inner walls of the two connecting columns 2, and the bottom of the multiple connecting pieces 1 is threaded to the top left and right sides of the base.

[0016] The above technical solution, through threaded connection, not only facilitates installation and disassembly, and makes equipment maintenance and repair easier, but also allows for appropriate adjustment of the connection tightness according to actual needs to adapt to the mechanical requirements under different working conditions. This ensures that the device maintains good working performance during long-term operation, improves the accuracy and consistency of intelligent clamping operations, reduces intelligent clamping quality problems caused by structural instability, and improves product qualification rate and production efficiency.

[0017] As a further description of the above technical solution:

[0018] A controller is fixedly connected to the front left side of the top of the base, and the controller is electrically connected to the alarm light.

[0019] Through the above technical solution, the entire device is equipped with intelligent pressure monitoring and alarm functions by prompting operators when abnormal conditions occur during the pressing process. This greatly improves the safety and reliability of the production process, effectively avoids smart card pressing quality problems or even equipment damage caused by pressure runaway, ensures smooth production operations and product quality stability, and also makes it easier for operators to detect and handle abnormal situations in a timely manner, reducing downtime caused by malfunctions and improving production efficiency.

[0020] As a further description of the above technical solution:

[0021] The top of the base is provided with a placement slot, and a rotating plate is rotatably connected to the top of the placement slot.

[0022] The above technical solution provides a dedicated storage space for small tools through a specially designed slot on the top of the base. During the intelligent clamping operation, commonly used small repair or debugging tools such as screwdrivers and wrenches can be placed in an orderly manner. The rotating plate connected to the top of the slot acts as a cover for the slot.

[0023] As a further description of the above technical solution:

[0024] The top of the rotating plate has a connecting hole, and a handle is fixedly connected to the inner wall of the connecting hole.

[0025] The above technical solution utilizes a connecting hole at the top of the rotating plate and a handle fixedly connected therein, which plays a crucial role. The connecting hole provides a stable attachment point for the handle, ensuring a tight integration between the handle and the rotating plate as a whole. The handle significantly enhances the ease of operation of the rotating plate. When the operator needs to open or close the placement slot, simply grasping the handle and applying gentle force allows the rotating plate to easily rotate around the connecting shaft at the top of the placement slot.

[0026] As a further description of the above technical solution:

[0027] The outer wall of the hydraulic cylinder is provided with a protective box, and the left and right sides of the outer wall of the protective box are fixedly connected with connecting pieces two. The bottom of the two connecting pieces two is threadedly connected to the top left and right sides of the fixed plate.

[0028] The above technical solution, through the threaded connection between the bottom of the connecting piece 2 and the top left and right sides of the fixed plate, not only is the protective box and the fixed plate tightly fixed, but also the installation, disassembly and maintenance of the protective box are facilitated. When the hydraulic cylinder needs to be inspected, maintained or replaced, the threads on the connecting piece 2 can be easily unscrewed to remove the protective box.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the pressure can be adjusted through the connecting column one, spring two and push plate to ensure that the smart card is evenly stressed, improve the pressing quality and accuracy, reduce the defect rate, and the pressure plate inside the connecting cylinder at the top of the plate is accurately monitored throughout the process, so that the operator can promptly grasp and deal with pressure abnormalities, ensure operational safety, avoid equipment failure, and the hydraulic cylinder drives the hydraulic plate to move smoothly, so as to make the pressing process continuous and stable, reduce jamming and shaking, and improve production efficiency.

[0031] 2. In this utility model, the height and level of the smart card pressing device can be comprehensively adjusted by the operator controlling the extension and retraction of the telescopic rod. The operation process is simple and quick, without the need for complicated tools and tedious calibration steps, which greatly saves equipment debugging and preparation time and improves the overall efficiency of production operations.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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.

[0040] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a smart card adaptive pressing device, comprising a base 1, with connecting columns 3 fixedly connected to the top left and right sides of the base 1, and fixing plates 4 fixedly connected to adjacent sides of the top of the two connecting columns 3, a hydraulic cylinder 5 fixedly connected to the top of the fixing plate 4, the output end of the hydraulic cylinder 5 penetrating through the top of the fixing plate 4 and fixedly connected to a hydraulic plate 7, connecting rods 6 rotatably connected to the front and rear sides of the outer wall of the fixing plate 4, the other end of the connecting rods 6 rotatably connected to the front and rear sides of the top of the hydraulic plate 7, and pressing blocks 8 fixedly connected to the front and rear sides of the bottom of the hydraulic plate 7, the outer walls of the two pressing blocks 8 being four The base 1 has multiple springs 9 fixedly connected to the bottom, and buffer blocks 10 fixedly connected to the other end of each spring 9. Multiple connecting columns 11 are fixedly connected to the bottom of the hydraulic plate 7. Springs 12 are provided on the outer walls of the multiple connecting columns 11. Push plates 13 are fixedly connected to the other ends of the multiple springs 12. A placement plate 14 is provided at the top center of the base 1. Multiple connecting cylinders 15 are fixedly connected to the top of the placement plate 14. Pressure plates 16 are fixedly connected to the inner walls of the multiple connecting cylinders 15. An alarm light 17 is fixedly connected to the right side of the outer wall of the right connecting column 3. An adjustment mechanism 2 is provided at the bottom of the base 1.

[0041] Specifically, when hydraulic cylinder 5 is activated, its output end begins to extend and retract. Since hydraulic plate 7 is connected to fixed plate 4 via connecting rod 6, when hydraulic cylinder 5 operates, it drives hydraulic plate 7 to move smoothly up and down. During the pressing process, the pressing block 8 at the bottom of hydraulic plate 7 first approaches the placement plate 14. Springs 9 and buffer blocks 10 around the outer wall of pressing block 8 first contact the smart card or the object being pressed. After the buffer block 10 is subjected to pressure, springs 9 are compressed, providing initial cushioning and preventing excessive instantaneous impact on the smart card. The card causes damage, making the initial stage of the pressing process relatively gentle. At the same time, the connecting column 11 at the bottom of the hydraulic plate 7, as well as the spring 12 and push plate 13 on its outer wall, also participate in the pressing process. As the pressing proceeds, after the push plate 13 contacts the smart card, the spring 12 will compress or extend accordingly according to the magnitude of the pressing pressure, further adjusting the pressure distribution during the pressing process, making the force on each part of the smart card more uniform, and improving the pressing quality. The pressure plate 16 inside the connecting cylinder 15 around the top of the placement plate 14 monitors the pressing pressure in real time.

[0042] Reference Figure 1 , Figure 2 and Figure 4 The adjustment mechanism 2 includes two connecting plates 201. The tops of the two connecting plates 201 are fixedly connected to the bottom left and right sides of the base 1. The bottoms of the two connecting plates 201 are rotatably connected to support rods 202. The bottoms of the two support rods 202 are slidably connected to support plates 203. The adjacent sides of the two support plates 203 are fixedly connected to horizontal plates 204. The top of the horizontal plates 204 is fixedly connected to telescopic rods 205. The top of the telescopic rods 205 is fixedly connected to the middle of the bottom of the base 1.

[0043] Specifically, when the height of the smart card pressing device needs to be adjusted, the telescopic rod 205 at the top of the horizontal plate 204 is activated. The telescopic movement of the telescopic rod 205 will directly act on the base 1, causing it to displace in the vertical direction. Since the two connecting plates 201 are fixed to the left and right sides of the bottom of the base 1 respectively and their bottoms are rotatably connected to the support rod 202, and the bottom of the support rod 202 is slidably connected to the support plate 203, when the height of the base 1 changes due to the action of the telescopic rod 205, the support rod 202 will rotate around the connection point with the connecting plate 201, and its bottom will slide accordingly on the support plate 203.

[0044] Reference Figure 1 , Figure 2 and Figure 4The top center of the base 1 has a connecting groove 18. The inner walls of the two connecting grooves 18 are fixedly connected to the left and right sides of the connecting cylinders 19. The top of the two connecting cylinders 19 is threaded with screws 20. The outer walls of the two connecting cylinders 19 are engaged with the placement plate 14. The inner walls of the two connecting pillars 3 are fixedly connected to multiple connecting pieces 21. The bottom of the multiple connecting pieces 21 is threaded to the top left and right sides of the base 1. The front left side of the top of the base 1 is fixedly connected to a controller 22. The controller 22 is electrically connected to the alarm light 17.

[0045] Specifically, the placement plate 14 is placed in the connecting groove 18 opened at the center of the top of the base 1, so that the outer wall of the connecting cylinder 19 engages with the placement plate 14, thereby limiting the placement plate 14 in the horizontal direction, ensuring its accurate position and preventing easy horizontal movement. By connecting the screw 20 to the top of the connecting cylinder 19 with a thread, after tightening the screw 20, the placement plate 14 is firmly fixed to the base 1 by the friction between the screw 20 and the placement plate 14 and the engaging action of the connecting cylinder 19. In this way, the placement plate 14 can be stably fixed during the smart card pressing process. The smart card is supported by the ground and will not be displaced due to the pressure, ensuring the accuracy of the pressing. The connecting piece 21 is fixed to the inner wall of the connecting post 3 and is connected to the top left and right sides of the base 1 by the bottom thread. This connection method makes the connecting post 3 and the base 1 tightly connected. The even distribution of the connecting pieces 21 can effectively disperse the force borne by the connection part. The pressure plate 16 inside the connecting cylinder 15 around the top of the placement plate 14 senses the pressure during pressing in real time. When the pressing pressure changes, the resistance value or other physical properties of the pressure plate 16 will change accordingly and generate an electrical signal.

[0046] Reference Figure 2 , Figure 3 and Figure 4 The top of the base 1 is provided with a placement groove 28, and a rotating plate 23 is rotatably connected to the top of the placement groove 28; the top of the rotating plate 23 is provided with a connection hole 24, and a handle 25 is fixedly connected to the inner wall of the connection hole 24; a protective box 26 is provided on the outer wall of the hydraulic cylinder 5, and connecting pieces 27 are fixedly connected to the left and right sides of the outer wall of the protective box 26, and the bottom of the two connecting pieces 27 are threadedly connected to the top left and right sides of the fixed plate 4.

[0047] Specifically, the placement slot 28 provides a dedicated storage space for small tools and other items. When items need to be stored, the operator can easily open the placement slot 28 by holding the handle 25, which is fixedly connected to the connecting hole 24 of the rotating plate 23. The handle 25 can easily rotate the rotating plate 23 around the rotating connection point with the top of the placement slot 28, so that the tools can be placed inside. When the items in the placement slot 28 are no longer needed, the rotating plate 23 can be rotated in the opposite direction to close the placement slot 28. The protective box 26 is wrapped around the outer wall of the hydraulic cylinder 5, which can effectively isolate the influence of dust, oil and moisture in the external environment on the hydraulic cylinder 5. The protective box 26 is connected to the top left and right sides of the fixed plate 4 by the connecting pieces 27 on the left and right sides of its outer wall, so that the protective box 26 can be firmly installed on the fixed plate 4, ensuring that the protective box 26 will not loosen or shift due to vibration or other external forces during the operation of the device.

[0048] Working principle: After the hydraulic cylinder 5 is activated, the extension and retraction of the output end of the hydraulic cylinder 5 causes the hydraulic plate 7 connected to it to move smoothly up and down through the rotating connection structure between the connecting rod 6 and the fixed plate 4. At the beginning of the pressing action, the pressing block 8 at the bottom of the hydraulic plate 7 moves towards the placement plate 14. The buffer structure on its outer wall, namely spring 9 and buffer block 10, first touches the smart card or the object being pressed. The buffer block 10 is forced to cause spring 9 to contract, effectively reducing the impact force at the initial contact, making the pressing start more moderate, and preventing the smart card from being damaged by instantaneous high pressure. At the same time, the connecting column 11 and its external spring 12 and push plate 13 also participate in the pressing process. As the pressing goes deeper, the push plate 13 contacts the smart card. Spring 12 extends and retracts flexibly according to the real-time pressing pressure, dynamically adjusting the pressure distribution to ensure that the force on each part of the smart card is balanced, improving the overall quality and accuracy of the pressing. Meanwhile, the pressure plate 16 in the connecting cylinder 15 at the top of the placement plate 14 accurately monitors the pressing pressure throughout the process.

[0049] Furthermore, when adjustment is required, the telescopic rod 205 starts working, driving the base 1. Since the top of the telescopic rod 205 is connected to the middle of the bottom of the base 1, its extension or retraction will cause the base 1 to produce a corresponding displacement in the vertical direction. The two connecting plates 201 serve as the connecting base 1, and the support rod 202 is rotatably connected to the connecting plates 201, moving with the height change of the base 1 to adapt to different angle requirements. At the same time, the bottom of the support rod 202 is slidably connected to the support plate 203, allowing the support rod 202 to slide on the support plate 203, thereby supporting and limiting the base 1 in the horizontal direction, ensuring that the base 1 will not shift or shake during height adjustment, and maintaining the stability of the overall structure.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
