Description

Technical Field

[0001] This utility model relates to the field of smart card electronic packaging technology, specifically a smart card module puncher. Background Technology

[0002] In the traditional contact smart card module manufacturing process, visual inspectors conduct a comprehensive inspection of the module's surface and metal surfaces according to the "Finished Product Inspection Operation Instruction." The inspector mounts the module to be inspected on the inspection workbench, slowly rotates the product tray, and visually inspects the module's surface quality. For defective modules, holes are drilled at standard locations for marking, and the number of defective modules is recorded. The location of the holes in defective modules is shown below. Figure 1 As shown, according to the standard, the mark should be placed on a fixed corner of the defective module.

[0003] In traditional drilling equipment, the drilling position of defective holes changes depending on the direction of the carrier belt feed. Operators need to frequently adjust the direction of the drilling equipment according to the direction of the carrier belt feed. In addition, traditional drilling equipment is difficult to accurately locate defective modules and is difficult to observe and judge the accuracy of drilling, which easily leads to drilling off-center or wrong holes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a smart card module puncher.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A smart card module puncher includes a base plate. A positioning plate is fixedly connected to the upper part of the base plate. A row of horizontally arranged positioning pins is provided on the upper part of the positioning plate. A bracket is fixedly provided on the upper part of the base plate. Two sets of punching mechanisms are slidably connected to the bracket. The two sets of punching mechanisms are arranged obliquely relative to the horizontal direction.

[0007] A punching plate is hinged to one end of the bracket and is located on the upper part of the bracket. An adjustment hole is provided on the punching plate and is located above the two sets of punching mechanisms. An adjustment slot is horizontally provided on the punching plate on both sides of the adjustment hole. A driving mechanism is slidably provided in the adjustment slot and the adjustment hole. The driving mechanism is used to drive the punching mechanism to perform the punching action. An observation hole is also provided on the punching plate.

[0008] In use of the above structure, the module to be damaged is placed on the positioning plate, below the punching mechanism, and the toothed holes of the carrier tape are hooked into the positioning pins. The punching position is determined according to the carrier tape direction. The driving mechanism in the adjustment hole of the punching plate is activated to select the punching quadrant, driving the corresponding punching mechanism to operate. The entire punching process is observed through the observation hole on the punching plate to ensure accurate punching position. The oblique arrangement of the two punching mechanisms ensures that, during operation, regardless of the carrier tape's feeding method, the direction of the punch does not need to be adjusted; only the driving mechanism needs to be adjusted to ensure consistent punching position.

[0009] The drilling mechanism includes a spindle that is vertically slidably connected to a bracket. A first limiting boss is provided at the upper end of the spindle, and a hole needle is fixedly connected to the bottom of the spindle. A first spring is sleeved on the outside of the spindle and is located between the first limiting boss and the bracket. After drilling is completed, the first spring drives the spindle to reset.

[0010] A pad is slidably fitted onto the lower part of the hole needle. A second spring is fixedly connected to the pad. The second spring is sleeved on the outside of the mandrel and the hole needle, and its upper end is fixedly connected to the mandrel. The pad can contact the upper surface of the module before the hole needle drills and press the module tightly during drilling, thereby ensuring accurate drilling position and ensuring that the module remains stable and does not move during the drilling process.

[0011] A second limiting boss is provided at the lower end of the mandrel. The second limiting boss is located at the lower part of the bracket, sleeved on the outside of the mandrel, and fixedly connected to the mandrel by a locating pin. The second limiting boss can control the upward movement of the mandrel, preventing excessive upward movement during the mandrel's reset and ensuring the initial position of the mandrel is stable.

[0012] The driving mechanism includes a driving rod that horizontally passes through the adjusting slot and the adjusting hole, and can slide longitudinally within the adjusting slot and the adjusting hole. The driving rod can be pressed against the upper part of the punching mechanism.

[0013] One end of the drive rod is fixedly connected to a first operating handle, which is convenient for the staff to grip.

[0014] The base plate is also equipped with a carrier tape flattening assembly, which includes a support plate fixedly mounted on the upper part of the base plate. A clamping plate is hinged to one end of the support plate and is positioned above the support plate. During drilling, the clamping plate and the support plate clamp the carrier tape in the middle, thereby ensuring the stability of the carrier tape. A second operating handle is connected to one end of the clamping plate, and the second operating handle is located away from the end of the clamping plate that is hinged to the support plate.

[0015] The positioning plate has two pads on its upper part, which are coaxial with the two drilling mechanisms in the vertical direction. The pads correspond one-to-one with the drilling mechanisms. During drilling, the corresponding drilling mechanism is set at the lower part of the module to provide support during the punching operation.

[0016] The beneficial effects achieved by this utility model are:

[0017] 1. This utility model uses a top drive rod to control two punching holes to punch holes for modules with different feeding methods. This achieves the goal of changing the punching position without moving the puncher when different feeding methods are used, making the operation more convenient.

[0018] 2. In this utility model, the punch uses a positioning target to position the carrier tape, thereby achieving the positioning of unqualified modules with high positioning accuracy and more accurate punching position.

[0019] 3. In this utility model, the puncher only has punching pins in the first and third quadrants, which ensures accurate punching position and eliminates accidental punching in the second and fourth quadrants.

[0020] 4. An observation hole is provided in this utility model to observe the entire drilling process, ensuring accurate drilling position and facilitating direct observation and operation by employees.

[0021] 5. The addition of a carrier tape flattening component in this utility model can significantly improve the stability of the tape and enhance the accuracy of the punching position. Attached Figure Description

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Example:

[0032] like Figures 1-6 As shown, a smart card module puncher includes a base plate 5. A positioning plate 13 is fixedly connected to the upper part of the base plate 5. A row of horizontally arranged positioning pins 17 is provided on the upper part of the positioning plate 13. There are four positioning pins 17 to ensure positioning accuracy. The positioning plate 13 provides support for the carrier belt 1. The positioning plate 13 and the positioning pins 17 provide positioning for the carrier belt 1.

[0033] A bracket 11 is fixedly installed on the upper part of the base plate 5. The bracket 11 is located on the upper part of the positioning plate 13. Two sets of drilling mechanisms are slidably connected to the bracket 11. The two sets of drilling mechanisms are arranged diagonally relative to the lateral direction. Specifically, the two sets of drilling mechanisms are arranged according to the first and third quadrants of module 3, that is, corresponding to the two positions of the defective hole 2 when there are two different feeding directions. Figure 1 In the state shown, during the existing operation, it is stipulated that the faulty hole 2 must be drilled in the upper right corner of the unqualified module 3.

[0034] like Figure 1 As shown, module 3 in row A is on top and module 3 in row B is on the bottom. When feeding in this manner, defective module 3 in row A is placed at the punching station. At this time, the punching mechanism in the first quadrant can punch holes in the defective module 3. When the carrier belt 1 reverses its feeding direction, as... Figure 6 As shown, module 3 in row B is on top and module 3 in row A is on the bottom. The punching mechanism located in the third quadrant can punch a hole in module 3 in row B (after reversing, the carrier belt 1 rotates 180 degrees, thereby causing module 3 in row B to rotate to the top, making the upper right corner of module 3 in row B the third quadrant).

[0035] One end of the bracket 11 is hinged to a punching plate 6, which is located on the upper part of the bracket 11. The punching plate 6 has an adjustment hole 9, which is located above the two sets of punching mechanisms. The punching plate 6 on both sides of the adjustment hole 9 has a horizontal adjustment groove 10. A driving mechanism is slidably arranged in the adjustment groove 10 and the adjustment hole 9. The driving mechanism is used to drive the punching mechanism to perform the punching action. The punching plate 6 also has an observation hole 7.

[0036] like Figure 3 , Figure 4 As shown, the punching mechanism includes a spindle 18 that is vertically slidably connected to the bracket 11. A first limiting boss 21 is provided at the upper end of the spindle 18. A hole needle 19 is fixedly connected to the bottom of the spindle 18. A first spring 22 is sleeved on the outside of the spindle 18. The first spring 22 is located between the first limiting boss 21 and the bracket 11. After punching is completed, the first spring 22 drives the spindle 18 to reset.

[0037] The pin 19 is inserted into the mounting hole at the bottom of the spindle 18 and locked in place by a pin.

[0038] A pad 20 is slidably sleeved on the lower part of the pin 19. A second spring 24 is fixedly connected to the pad 20. The second spring 24 is sleeved on the outside of the mandrel 18 and the pin 19, and its upper end is fixedly connected to the mandrel 18. The pad 20 can contact the upper surface of the module 3 before the pin 19 drills a hole, and presses the module 3 firmly during drilling, ensuring the module 3 remains stable and does not move during the drilling process, thus ensuring accurate drilling position. The pad 20 is made of copper.

[0039] A second limiting boss 23 is provided at the lower end of the mandrel 18. The second limiting boss 23 is located at the lower part of the bracket 11, and is sleeved on the outside of the mandrel 18 and fixedly connected to the mandrel 18 by a positioning pin. The second limiting boss 23 can control the upward movement of the mandrel 18, preventing the mandrel 18 from moving too high when resetting, and ensuring the initial position of the mandrel 18 is stable.

[0040] The driving mechanism includes a driving rod 8, which horizontally passes through the adjusting slot 10 and the adjusting hole 9, and can slide longitudinally within the adjusting slot 10 and the adjusting hole 9. The driving rod 8 can be pressed against the upper part of the punching mechanism. One end of the driving rod 8 is fixedly connected to a first operating handle 12 for easy gripping by the operator.

[0041] like Figure 2 , Figure 5As shown, a carrier tape flattening assembly is also provided on the base plate 5, and the carrier tape flattening assembly is located on one side of the positioning plate 13. The carrier tape flattening assembly includes a support plate 15 fixedly installed on the upper part of the base plate 5. A clamping plate 14 is hinged to one end of the support plate 15. The clamping plate 14 is located on the upper part of the support plate 15. When drilling, the clamping plate 14 and the support plate 15 clamp the carrier tape 1 in the middle, thereby ensuring the stability of the carrier tape 1. A second operating handle 16 is connected to one end of the clamping plate 14. The second operating handle 16 is located away from the end of the clamping plate 14 that is hinged to the support plate 15.

[0042] The positioning plate 13 has two pads 25 on its upper part, and the two pads 25 are coaxial with the two punching mechanisms in the vertical direction. The pads 25 correspond one-to-one with the punching mechanisms. When punching, the corresponding punching mechanism is set at the lower part of the module 3 to serve as support during the punching operation.

[0043] The method of using this utility model is as follows: observe through the observation hole 7 on the punching pressure plate 6, place the module 3 to be damaged on the positioning plate 13 and below the punching mechanism, and hang the tooth hole 4 of the carrier tape 1 into the positioning pin 17 to ensure accurate positioning. Then, use the pressing plate 14 of the carrier tape flattening assembly to clamp the carrier tape 1 between the pressing plate 14 and the support plate 15.

[0044] Determine the quadrant where the punching is located based on the direction of the carrier belt 1. Then, move the drive rod 8 in the adjustment hole 9 so that the drive rod 8 is located on the upper part of the mandrel 18 corresponding to that quadrant. Finally, manually press the punching plate 6. The punching plate 6 drives the drive rod 8 downward, the drive rod 8 drives the mandrel 18 downward, and the mandrel 18 drives the hole needle 19 to slide downward relative to the bracket 11, thereby completing the punching action.
