Description

Technical Field

[0001] This utility model relates to the field of chip processing technology, specifically a marking machine for processing cryptographic chips. Background Technology

[0002] Chip PIN refers to the Personal Identification Number (PIN) integrated on a bank card. Chip PIN cards integrate a smart chip that can more securely store personal identification information. It is the most important part of the electronic device, undertaking computation and storage functions. Chips integrate many electronic components onto a silicone plate to form circuits that achieve specific functions. Therefore, many chips need to be marked to distinguish their functions, such as with patterns, numbers, and other information. This requires laser marking machines to mark the chip surface.

[0003] In existing technologies, laser marking machines use high-energy-density lasers to irradiate the surface of chips, causing the surface material to vaporize or change color, thus leaving a permanent mark. However, during the chip marking process, after one chip is marked, it takes a long time to replace the next chip and continue marking, resulting in poor marking efficiency. Moreover, after the chips are marked, they often need to be manually removed and unloaded, making the chip unloading operation not automated and convenient enough. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a marking machine for processing cryptographic chips, which solves problems such as poor chip marking efficiency and insufficient automatic and convenient unloading.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a marking machine for processing cryptographic chips, comprising a machine body and a laser marking head, wherein the laser marking head is installed on the top of the machine body;

[0006] The machine body is equipped with a worktable, and marking tables are fixed around the perimeter of the worktable. The marking table has a storage opening that runs vertically through the center. Two support plates are installed inside each storage opening. A storage recess is provided on the upper left side of the machine body. Proximity switches are installed on the outer side of the lower end of the marking table. A proximity plate corresponding to the proximity switch is connected to the upper side of the storage recess. A rotary braking assembly is provided below the worktable.

[0007] Both sides of the inner wall of the storage opening have storage slots, and each storage slot is equipped with an electromagnetic adsorption component.

[0008] Preferably, the rotary braking assembly includes a brake motor, a PLC controller, a main gear, a support shaft, and a secondary gear, with the brake motor and the PLC controller both fixed to the upper end of the machine body.

[0009] Preferably, the main gear is connected to the power end of the brake motor, one end of the support shaft is fixed to the lower end of the workbench, and the other end of the support shaft is rotatably connected to the upper end of the machine body, the auxiliary gear is fixedly sleeved around the support shaft, and the main gear meshes with the auxiliary gear.

[0010] Preferably, each of the electromagnetic adsorption components includes an electromagnet, a guide rod, a sliding plate, a magnetic block, and a return spring. The electromagnets are all connected to the inner sidewall of the storage groove, the guide rods are all fixed inside the storage groove, the sliding plates are all slidably sleeved around the guide rods, and the support plates are all fixed to the adjacent sliding plates.

[0011] Preferably, the magnetic blocks are all connected to the side of the sliding plate, the electromagnets are all corresponding to the adjacent magnetic blocks, and the return springs are all connected between the side of the sliding plate and the inner wall of the storage groove.

[0012] Preferably, a storage battery is embedded in the upper part of the workbench, all proximity switches are connected in series with the storage battery, and all electromagnets are connected in series with adjacent proximity switches.

[0013] This utility model provides a marking machine for processing cryptographic chips, which has the following advantages:

[0014] By setting up four marking stations, once the chip in the previous marking station is marked, the rotating braking component drives the four marking stations to rotate until the chip in the next marking station is directly below the laser marking head. This process is repeated, which facilitates quick switching to the next chip for marking, effectively improving the efficiency of chip marking. Moreover, after the chip is marked, when the corresponding marking station is directly above the receiving recess, the support plate automatically retracts into the storage slot. Therefore, the chip in the storage opening will automatically fall into the receiving recess for collection, which facilitates automatic unloading without the need for manual unloading, making the unloading operation automatic and convenient.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a marking machine for processing cryptographic chips, including a body 1 and a laser marking head 2. The laser marking head 2 is installed above the body 1. A worktable 3 is provided on the body 1. Marking tables 4 are fixed around the perimeter of the worktable 3. A vertically penetrating storage opening 5 is opened in the middle of the marking table 4. Two support plates 6 are provided in each storage opening 5. A storage recess 7 is provided on the upper left side of the body 1. Proximity switches 8 are installed on the outer side of the lower end of the marking table 4. The upper end of the outer side of the storage recess 7 is connected to a corresponding proximity switch 8. The approach plate 9 is provided below the worktable 3, and a rotary braking assembly is provided. The rotary braking assembly includes a brake motor 17, a PLC controller 18, a main gear 19, a support shaft 16, and a secondary gear 20. The brake motor 17 and the PLC controller 18 are both fixed to the upper end of the machine body 1. The main gear 19 is connected to the power end of the brake motor 17. One end of the support shaft 16 is fixed to the lower end of the worktable 3, and the other end of the support shaft 16 is rotatably connected to the upper end of the machine body 1. The secondary gear 20 is fixedly sleeved around the support shaft 16, and the main gear 19 meshes with the secondary gear 20.

[0022] By setting up four marking stations 4 and placing the password chip to be marked in the storage port 5 of the marking station 4, and then supporting the chip with a support plate 6, after the chip in the previous marking station 4 is marked by the laser marking station 4, the PLC controller 18 is set to be electrically connected to the brake motor 17. After the PLC controller 18 controls the brake motor 17 to work, the brake motor 17 drives the main gear 19, the auxiliary gear 20, the support shaft 16, the processing table and the marking station 4 to rotate until the chip in the next marking station 4 is located directly below the laser marking head 2. This process is repeated, which facilitates the rapid switching of the next chip for marking processing and effectively improves the efficiency of chip marking processing.

[0023] In this embodiment, storage slots 10 are formed on both sides of the inner wall of the storage opening 5. Each storage slot 10 is equipped with an electromagnetic adsorption assembly, which includes an electromagnet 12, a guide rod 14, a sliding plate 11, a magnetic block 13, and a return spring 15. The electromagnets 12 are connected to the inner wall of the storage slot 10, the guide rods 14 are fixed in the storage slot 10, the sliding plates 11 are slidably sleeved around the guide rods 14, the support plates 6 are fixed to the adjacent sliding plates 11, the magnetic blocks 13 are connected to the side of the sliding plates 11, the electromagnets 12 are corresponding to the adjacent magnetic blocks 13, and the return springs 15 are connected between the side of the sliding plates 11 and the inner wall of the storage slot 10. A battery 21 is embedded in the upper end of the workbench 3, the proximity switches 8 are connected in series with the battery 21, and the electromagnets 12 are connected in series with the adjacent proximity switches 8.

[0024] When the chip marking is completed and the corresponding marking platform 4 is located at the top of the receiving recess 7, the proximity switch 8 senses the approach of the proximity plate 9. Therefore, the proximity switch 8 is activated and the electromagnet 12 is powered by the battery 21. The electromagnet 12 generates a magnetic force and attracts the magnetic block 13. The magnetic block 13 will drive the sliding plate 11 to slide along the guide rod 14. At this time, the sliding plate 11 will compress the return spring 15. At the same time, the sliding plate 11 will drive the support plate 6 to automatically retract into the storage slot 10, thereby opening the storage port 5. Therefore, the chip in the storage port 5 will automatically fall into the receiving recess 7 for collection, which is conducive to achieving the effect of automatic unloading. There is no need for manual unloading, making the unloading operation automatic and convenient.

[0025] In this embodiment, all electromagnets 12 are connected to the inner wall of the storage groove 10, all guide rods 14 are fixed inside the storage groove 10, all sliding plates 11 are slidably sleeved around the guide rods 14, all support plates 6 are fixed to adjacent sliding plates 11, all magnetic blocks 13 are connected to the side of the sliding plate 11, all electromagnets 12 correspond to adjacent magnetic blocks 13, and all return springs 15 are connected between the side of the sliding plate 11 and the inner wall of the storage groove 10.

[0026] When the proximity switch 8 on the corresponding marking table 4 no longer senses the proximity plate 9, the proximity switch 8 automatically disconnects and the electromagnet 12 is de-energized. Then, the return force of the return spring 15 will drive the sliding plate 11 to slide and reset along the guide rod 14. The sliding plate 11 will also drive the support plate 6 to extend out of the storage slot 10 until the support plate 6 can support the chip normally, so that the chip can continue to be placed into the storage port 5 for marking processing.

[0027] Working principle:

[0028] The brake motor 17 drives the main gear 19, the secondary gear 20, the support shaft 16, the processing table, and the marking table 4 to rotate until the chip in the next marking table 4 is located directly below the laser marking head 2. This process is repeated to facilitate quick switching to the next chip for marking. When the chip is marked and the corresponding marking table 4 is located directly above the receiving recess 7, the proximity switch 8 senses the approach of the proximity plate 9. Therefore, the proximity switch 8 is activated and the battery 21 powers the electromagnet 12. The electromagnet 12 generates a magnetic force and attracts the magnetic block 13. The magnetic block 13 then drives the sliding plate 11 to slide along the guide rod 14. At the same time, the sliding plate 11 drives the support plate 6 to automatically retract into the storage slot 10, thereby opening the storage opening 5. Therefore, the chip in the storage opening 5 will automatically fall into the receiving recess 7 for collection.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
