Technical Field

[0001] This utility model relates to the field of smart card module processing technology, and in particular to a high-precision cutting device for smart card modules. Background Technology

[0002] With the rapid development of the Internet of Things, mobile payment, and other fields, the application scenarios of smart card modules continue to expand, and the requirements for their dimensional accuracy, edge flatness, and processing efficiency are becoming increasingly stringent. Traditional cutting devices mostly use mechanical punching or simple blade cutting technology. The former is prone to decrease in accuracy due to mold wear during long-term use, and cannot meet the processing requirements of micro smart card modules; the latter has the problems of many burrs on the cutting edges and easy material deformation, requiring additional grinding processes, which significantly extends the production cycle.

[0003] Meanwhile, the demand for customized smart card modules is growing significantly, and different sizes and shapes of processing tasks often need to be switched on the same production line. The cutting parameters of traditional devices rely on manual adjustment of molds or guide rails, which is not only cumbersome and time-consuming, but also prone to affecting product consistency due to human error. Therefore, a high-precision cutting device for smart card modules has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision cutting device for smart card modules.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-6A high-precision cutting device for smart card modules includes a worktable 1. A rectangular frame 2 is fixedly embedded at one end of the top of the worktable 1. A rectangular hole adapted to the rectangular frame 2 is opened on the worktable 1. A U-shaped plate 4 is arranged inside the rectangular frame 2, and movable strips 203 are fixedly connected to both sides of the bottom of the U-shaped plate 4. A slide rod 202 is slidably sleeved on one of the movable strips 203. A circular hole adapted to the slide rod 202 is opened on the movable strip 203, and the slide rod 202 is fixedly connected to both ends of the rectangular frame 2. A lead screw 201 is screwed onto the other movable strip 203. A screw nut that matches the screw 201 is fixedly sleeved in the middle, and both ends of the screw 201 are rotatably connected to the two ends of the rectangular frame 2. A knob is fixedly connected to one end of the screw 201 through the rectangular frame 2. By rotating the screw 201, the two punching mechanisms 5 can be switched quickly. Punching mechanisms 5 are provided at both ends of the top of the U-shaped plate 4. The punching mechanism 5 includes a fixed platform 501 with one end of the top of the U-shaped plate 4. A square hole is opened in the middle of the fixed platform 501, and a guide plate 502 is fixedly connected in the middle of the square hole. A punching hole 503 is opened at the top of the fixed platform 501.

[0018] In this utility model, the punching mechanism 5 also includes fixed rods 504 fixedly connected to the four corners of the top of the fixed platform 501. Each fixed rod 504 has a sleeve 506 fixedly fitted at its bottom. The same lifting plate 507 is slidably fitted at the top of the four fixed rods 504. Sliding sleeves adapted to the fixed rods 504 are fixedly fitted at the four corners of the lifting plate 507. A limit block is fixedly connected to the top of each fixed rod 504. A first spring 505 is fitted between the sleeve 506 and the lifting plate 507 of each of the four fixed rods 504. The setting of the first spring 505 ensures that the lifting plate 507 and the top block 508 are always at the highest position when there is no external force.

[0019] In this utility model, the punching mechanism 5 also includes a top block 508 fixedly connected to the middle of the top of the lifting plate 507, and the top of the top block 508 is provided with a T-shaped groove 509, and the bottom of the lifting plate 507 is fixedly connected with a punching blade, and the punching blade is adapted to the punching hole 503.

[0020] In this utility model, both ends of the bottom of the U-shaped plate 4 are provided with limiting mechanisms 6. The limiting mechanism 6 includes two fixing blocks 601 fixedly connected to the bottom of the U-shaped plate 4. Two connecting rods 602 are fixedly connected between the two fixing blocks 601. Both ends of the two connecting rods 602 are slidably fitted with L-shaped locking blocks 604. The U-shaped plate 4 and the fixing platform 501 are both provided with locking holes that are adapted to the L-shaped locking blocks 604.

[0021] In this utility model, the limiting mechanism 6 also includes a second spring 603 with two connecting rods 602 fixedly sleeved between two L-shaped blocks 604, and the top of the L-shaped blocks 604 are provided with inclined surfaces on the opposite sides. The setting of the limiting mechanism 6 makes it easy to replace the two punching mechanisms 5.

[0022] In this utility model, a support platform 3 is fixedly connected to the top of the workbench 1 at the middle of the rectangular frame 2.

[0023] In this utility model, a cylinder 301 is fixedly connected to the middle of the top of the support platform 3, and a T-shaped block 302 is fixedly connected to the bottom output end of the cylinder 301 through the support platform 3.

[0024] In this utility model, the T-shaped block 302 is adapted to two T-shaped slides 509. The cooperation between the T-shaped block 302 and the T-shaped slides 509 allows both punching mechanisms 5 to cooperate with the T-shaped block 302 when they move.

[0025] Working principle: When in use, cylinder 301 is connected to the air pump via a solenoid valve and pipeline. The user places the blank to be punched on top of the punching hole 503. The extension of cylinder 301 causes T-block 302 to lower the top block 508 and lifting plate 507, compressing the four first springs 505. The lowering of the lifting plate 507, combined with the punching blade's engagement with the punching hole 503, cuts the blank. The cut material is guided by the guide plate 502 and slides onto the worktable 1, awaiting collection by the operator. After completion, cylinder 301 retracts, and the four first springs 505 extend, causing the lifting plate 507 and the top block... The reset of 508 achieves stable punching. When it is necessary to change the punching tool, by rotating the knob at one end of the lead screw 201, the lead screw 201 drives the U-shaped plate 4 to move, so that another punching mechanism 5 moves to the middle of the rectangular frame 2. At the same time, the T-shaped block 302 slides out from the previous T-shaped slide 509 and slides into the new T-shaped slide 509, thus realizing the replacement of the punching tool, which is faster than Na Jie. At the same time, by pressing the two L-shaped locking blocks 604 of the bottom limiting mechanism 6, the two L-shaped locking blocks 604 move closer to each other and compress the second spring 603, so that the L-shaped locking blocks 604 can be separated from the bottom of the fixed table 501, realizing the replacement of the entire punching mechanism 5.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
