[0057] Specifically, such as Figure 6As shown, the RFID reader / writer 52 is fixed on the tabletop 21 by the reader / writer mounting plate 51. Multiple RFID readers / writers are installed at the same time. Since multiple RFID readers / writers 52 are adjacent, information reading may be disordered. Therefore, a blocking shielding plate 53 is installed between multiple RFID readers / writers 52 to block the signal. The blocking shielding plate 53 is made of anti-interference sheet metal structure to avoid disorder when the robot module picks up the identification card for information reading, and to ensure that the information read from the identification card is correct.

It is used to fix the marking card 00 in the marking position under the drive of the vertical cylinder 683 and the horizontal cylinder 685.

[0067] The second marking limit block 69 is located on the opposite side of the first marking limit block 68 and cooperates with the first marking limit block 68 to fix the identification card 00. It includes a fixed moving plate 691, a limit cylinder mounting plate 692, a limit cylinder 693, and a second limit block 694. The fixed moving plate 691 is located on the table 21, the limit cylinder mounting plate 692 is fixed on the fixed moving plate 691, the limit cylinder 693 is located on the limit cylinder mounting plate 692, and the second limit block 694 is located on the limit cylinder 693. It is used to fix the identification card 00 at the marking position under the drive of the limit cylinder 693.

[0068] Specifically, such as Figure 7-11 As shown, the robot module 30 picks up the identification card and places it into the buffer mechanism 62 for temporary storage. The buffer mechanism 62 is mounted on the table 21 via a buffer tray bracket 621. A buffer tray pad 622 is mounted on the buffer tray bracket 621, and multiple card slot trays 623 are mounted on the buffer tray pad 622 for storing identification cards 00. Each card slot tray 623 is equipped with a card slot sensor 624 to detect whether an identification card 00 is loaded in the corresponding card slot tray 623. The support plate 625 is fixed to the table. On surface 21, a first cylinder 626 and a second cylinder 627 are installed. The second cylinder 627 is positioned above the first cylinder 626 and is connected to a buffer gripper mounting plate 628. A third cylinder 629 and a buffer gripper 620 connected to the third cylinder 629 are mounted on the buffer gripper mounting plate 628. Under the control of the first cylinder 626, the second cylinder 627, and the third cylinder 629, the buffer gripper 620 clamps the identification card 00 onto the transfer mechanism 61 for subsequent testing. Furthermore, after testing, the buffer gripper 620 also clamps the identification card onto the card slot tray 623 for buffering.

[0069] The transfer mechanism 61 is equipped with a linear guide rail 611, on which a bakelite tray 613 is mounted. The bakelite tray 613 slides on the linear guide rail 611 under the drive of the transfer motor 612. The bottom of the bakelite tray is an aluminum base plate to avoid metal interference during subsequent testing. The bakelite tray 613 contains the identification card transferred by the transfer mechanism 62. By sliding on the linear guide rail 611, the first posture test of the identification card, screen detection, product flipping, RFID distance test, second posture detection, and product marking operation are performed sequentially. The sensor bracket 614 is set at the initial position of the transfer mechanism 61 and is positioned opposite to the buffer mechanism 62. The material sensor 615 is installed on the top of the sensor bracket 614 and corresponds one-to-one with the part slots of the bakelite tray 613 to detect whether there is an identification card in the bakelite tray 613. When an identification card is present, the drive motor is activated to drive the bakelite tray 613 to slide for identification card testing.

[0070] The bakelite tray 613 slides along the linear guide rail 611 to the first shielding test mechanism 63. Assuming the bakelite tray 613 has three identification card positions, during testing, position one of the bakelite tray 613 is first transported to the first shielding test mechanism 63. The shielding box descends, and a control substation is set up inside the shielding box. The substation performs the first posture detection on the identification card. For example, if it is a K9 model identification card, the control substation issues a screen lighting test, the shielding box rises, and the host computer controls the vision inspection mechanism 64 to perform screen lighting detection on the K9 model identification card. If it is a K3 or K5 model identification card, position one of the trays will be directly transported to the next station, while position two of the trays arrives at the first shielding box debugging mechanism.

[0071] The bakelite tray 613 slides to the flipping mechanism 65. The lifting cylinder 652 and the clamping cylinder 656 control the flipping gripper 658 to pick up the identification card in the bakelite tray 613. Then, the rotating cylinder 655 controls the flipping gripper 658 to flip the identification card. Under the control of the lifting cylinder 652 and the clamping cylinder 656, the identification card is put back into the bakelite tray 613. At the same time, the distance detector locates a position 1m away from the identification card and reads the signal of the identification card to check the qualification of the label signal of the identification card.

[0072] After reading is completed, the device moves to the second shielding test mechanism 66. At this time, the tray position two flipping mechanism 65 is in place, and the tray position three first shielding box debugging mechanism 63 is in place, enabling simultaneous testing of multiple identification cards and improving work efficiency. The second shielding test mechanism 66 detects the second posture of the identification card after flipping. If the identification card model is K9, the control substation will also send a signal to turn off the screen and perform a screen off test. After the process is completed, the bakelite tray 613 will move from the first station to the marking station.

[0073] During laser marking, the marking card in the bakelite tray is positioned by the first marking limit block 68 and the second marking limit block 69. The lifting body 671 controls the lifting of the main beam 672, which drives the marking head 673 to move in the vertical direction to mark the marking card. At the same time, the smoke machine in the smoke hood 674 is started to absorb the smoke.

[0074] The marking station consists of a first marking limit block 68, a second marking limit block 69, and a laser marking machine 67. After the bakelite tray 613 is in place, the first marking limit block 68 and the second marking limit block 69 extend to limit the marking card to one corner of the bakelite tray 613, thereby improving the marking accuracy. At the same time as marking, the smoke machine in the smoke hood 674 works to perform the smoke removal process.

[0075] The first marking limit block 68 is fixed on the table 21 by a movable fixing plate 681, and its position can be adjusted on the table 21 by the movable fixing plate 681 to a better positioning position; the first limit block 686 is driven by the vertical cylinder 683 and the horizontal cylinder 685 to fix the label card in the marking position. The first limit block 686 can be set to T-shape to facilitate the positioning of the label card.

[0076] The second marking limit block 69 is located on the opposite side of the first marking limit block 68. The two work together to position the adjacent side of the identification card 00. Similar to the first marking limit block 68, the first marking limit block can be adjusted on the table 21 by fixing the moving plate 691. The second limit block 694 is driven by the limit cylinder 693 to position the identification card. The second limit block 694 has the same structure as the first limit block 686.

[0077] After marking is completed, the bakelite tray 613 returns to the initial position of the module. Once in position, the buffer mechanism 62 is activated, and the buffer gripper 620 extends to pick up the identification card 00 and place it into the card slot tray 623 for buffering, completing one round of test marking operation for the tray identification card. Then, the robot module 30 is ready to unload the identification card.

[0078] The NG unloading module 70 includes an NG mounting frame 71, a speed-regulating motor 72, a speed controller 73, a first reflection sensor 74, a second reflection sensor 75, and a flat belt 76. The speed-regulating motor 72 is fixed on the table 21 via the NG mounting frame 71 and is used to drive the flat belt 75 to rotate. The speed controller 73 is used to adjust the transmission speed of the flat belt 76. The flat belt 76 is set on the NG mounting frame 71. The first reflection sensor 74 and the second reflection sensor 75 are set at both ends of the flat belt 75. The first reflection sensor 74 is used to detect whether NG products are put in, and the second reflection sensor 75 is used to detect whether the flat belt 76 is full.

[0079] Specifically, since defective products may occur during the assembly and labeling process, an NG belt unloading module 70 can be installed on the table 21 via the NG mounting bracket 71 for the temporary recycling of NG products. For example... Figure 12 As shown, when the first reflection sensor 74 detects an NG (non-compliant) item being placed in the belt, the speed-regulating motor 72 drives the flat belt 76 to move one part position, making room for the next part. As the number of NG items gradually increases, the first NG item triggers an alarm on the second reflection sensor 75, prompting the operator to remove the NG item. The speed-regulating motor 72 is equipped with a corresponding speed controller 73 to adjust the transmission speed of the flat belt 106 and prevent slippage.

[0080] The loading and unloading machine 80 includes a loading and unloading machine frame 81, a loading and unloading mechanism 82, a lifting mechanism 83, a loading and unloading pallet 84, an empty pallet receiving mechanism 85, an empty pallet placing mechanism 86, a front door 87, and an electrical control cabinet 88.

[0081] The loading / unloading mechanism 82 is located at the bottom of the loading / unloading frame 81 and is used to place pallets. It includes: a cylinder mounting plate 821, a rodless cylinder 822, a slide rod 823, a slide rod mounting plate 824, a pallet placement plate 825, a lower guide plate 826, and a pallet-to-pallet sensor 827. The cylinder mounting plate 821 is fixed to the bottom of the loading / unloading frame 81. The rodless cylinder 822 is mounted on the cylinder mounting plate 821. The slide rod 823 is matched with the rodless cylinder 822 and can move under the drive of the rodless cylinder 822. The slide rod mounting plate 824 is located on top of the slide rod 823 and is used to mount the slide rod 823. The pallet placement plate 825 is located on the slide rod mounting plate 824 and is used to place part pallets. The lower guide plate 826 is located on the loading / unloading frame 81 and is used for guiding the lifting and lowering of the part pallets. The pallet-to-pallet sensor 827 is located on both sides of the pallet placement plate 825 and is used to detect whether a part pallet is placed on the pallet placement plate 825.

[0082] A lifting mechanism 83 is located on one side of the loading / unloading frame 81. It is used to lift the pallet placed on the loading / unloading mechanism 82 to the identification card retrieval position for loading, or to lower the pallet filled with identification cards to the loading / unloading mechanism for unloading. The mechanism includes: a drive motor 831, a guide rail mounting plate 832, a lead screw 833, a lifting plate 834, and a lifting guide rail 835. The drive motor 831, guide rail mounting plate 832, lead screw 833, and lifting guide rail 835 are all fixed to the loading / unloading frame 81. The lifting plate 834 is connected to the lead screw 833 and the lifting guide rail 835, and is able to move up and down on the lifting guide rail 835 under the drive of the drive motor 831, thereby loading and unloading the parts pallet. The lifting guide rail 835 is mounted on the guide rail mounting plate 832.

[0083] The loading / unloading pallet 84 is located on top of the loading / unloading frame 81 and is used to load the identification card 00 and move the empty pallet to the empty pallet receiving mechanism 85. It includes: a parts pallet 841, a full-load positioning assembly 842, a pallet pressure plate 843, an upper guide plate 844, and a full-load sensor 845. The parts pallet 841 is located at the parts pick-and-place position of the loading / unloading frame 81. The full-load positioning assembly 842 is located at both ends of the parts pallet 841 and includes a positioning push plate 8421, a push cylinder 8422, and a push cylinder mounting plate 8423. The cylinder mounting plate 843 is fixed to the loading / unloading frame 81, and the cylinder 8422 is mounted on the cylinder mounting plate 8423. The positioning push plate 8421 is connected to the cylinder 8422 and is used to push the part pallet 841 to the empty pallet receiving mechanism. The pallet pressure plate 843 is located above the part picking and placing position and is used to position the height of the part pallet. The upper guide plate 844 is located on the loading / unloading frame 81 and is used to guide the part pallet. The full material sensor 845 is located below the part picking and placing position and is used to detect the full material of the pallet.

[0084] An empty tray receiving mechanism 85 is located below an empty tray placement mechanism 86 and is used to move empty trays after loading to the empty tray placement mechanism 86. It includes a base plate 851, a translation cylinder 852, a lifting cylinder 853, an empty tray placement plate 854, and a receiving plate 855. The translation cylinder 852 and the lifting cylinder 853 are both located on the base plate 851. The empty tray placement plate 854 is connected to the lifting cylinder 853, and under the lifting action of the lifting cylinder 853, it pushes the empty tray to the empty tray placement mechanism 86. The receiving plate 855 is connected to the translation cylinder 852, and under the pushing action of the translation cylinder 852, it receives the empty tray and moves it to the empty tray placement plate 854.

[0085] The empty pallet placement mechanism 86 is used to stack empty pallets and includes: a pallet placement plate 861, a pallet guide plate 862, a receiving pad 863, and a full material through-beam sensor 864; the pallet placement plate 861 is fixed on the loading / unloading frame 81, the pallet guide plate 862 and the receiving pad 863 are disposed on the pallet placement plate 861, and the full material through-beam sensor 864 is disposed on the top of the pallet guide plate 862 for detecting whether the empty pallet placement mechanism 86 is full.

[0086] The front door 87 and the lifting mechanism 83 are arranged opposite each other; the electrical control cabinet 88 is used to control the loading and unloading machine 80 to load and unload materials.

[0087] Specifically, such as Figure 13-19 As shown, the loading and unloading machine 80 is used for testing and unloading of identification cards after marking. Since the loading and unloading machine 80 is a structure independent of the overall system, it can also be moved to the system that needs to be loaded when loading is required.

[0088] During unloading, the parts pallet descends via the lower guide plate 826 and eventually stops on the pallet placement plate 825. The pallet-to-light sensor 827 detects the presence of a parts pallet requiring unloading. Based on the cooperation of the rodless cylinder 822 and the slide rod 823, the pallet placement plate 825 containing the parts pallet is driven to move towards the front door 87 to facilitate pallet unloading. The principle is similar during loading.

[0089] The lifting mechanism 83 drives the parts pallet filled with parts to descend. The drive motor 831 uses the lead screw 833 to drive the lifting plate 834 to rise and fall on the lifting guide rail 835. The lifting plate 834 is set below the loading and unloading pallet 84. When unloading is required, it drives the parts pallet 841 to descend.

[0090] The parts pallet 841 is located at the parts pick-and-place position of the loading / unloading frame 81 and is used to load the qualified identification cards gripped by the robot module 30. During loading, the positioning push plate 8421 can be pushed by the push cylinder 8422, which in turn pushes the parts pallet 841 to the empty pallet receiving mechanism. During unloading, there is no need for the full material positioning component 842 to push. The pallet pressure plate 843 is set above the parts pallet 841 to position the height of the lifted parts pallet 841. The upper guide plate 844 is used to guide the upper part when the parts pallet is lifted and lowered. At the same time, a full material sensor is set up to stop the lifting and lowering operation when a parts pallet is detected to be passing by.

[0091] Driven by the translation cylinder 852, the empty tray receiving mechanism 85 receives the empty tray pushed by the positioning push plate 8421 through the receiving plate 855 and resets it to the empty tray placement plate 854. At this time, the empty tray is located on the empty tray placement plate 854. The empty tray placement plate 854 is lifted by the lifting cylinder 853, and the empty tray is lifted to the empty tray placement mechanism 86, thereby realizing the recycling of the empty tray.

[0092] The lifting cylinder 853 lifts the empty pallet onto the receiving pad 863 of the empty pallet placement mechanism 86. When the empty pallet is lifted, it can be guided upward by the pallet guide plate 862. The empty pallet is continuously recycled until the full material photoelectric sensor detects the empty pallet. This indicates that the empty pallet on the empty pallet placement mechanism 86 is full, prompting the staff to unload the empty pallet, thereby realizing the automated recycling of the empty pallet.

[0093] The system utilizes technologies such as articulated robotic arms, machine vision, and laser displacement detection to achieve precise positioning, gripping, and unloading of parts, while simultaneously inspecting and marking the design structure. This improves product testing and marking efficiency, and the integrated unloading machine simplifies and speeds up the unloading process.

[0094] This invention's system can accurately transfer identification cards. The grippers designed on the 4-axis robot can accurately and efficiently pick up and place the identification cards, playing a crucial role in handling and unloading products. The unique design of the RFID reader / writer greatly improves the accuracy of reading and writing product information. The detection and marking module design allows for simultaneous detection and marking at several workstations, significantly increasing product output speed and production efficiency. The unloading machine is a modular integrated device, which also greatly reduces production costs and improves production efficiency.

[0095] Furthermore, the system of this invention can also be integrated with the digital management systems of modern intelligent factories (such as ERP, PLM, PDM and MES systems), enabling products to be stored in an intelligent factory-level storage center via industrial control computers, facilitating the collection of production data and product quality traceability.

[0096] In one embodiment, such as Figure 20 As shown, a method for testing and marking identification cards is also provided, which is implemented using an identification card testing and marking system as described above, including:

[0097] Step S110: The robot module grabs the identification card from the shuttle module and transfers it to the RFID reader to read the RFID information.

[0098] Step S120: The identification card after information reading is tested through the test line, including first posture test, screen detection, product flipping, RFID distance test, second posture detection, product marking and product caching.

[0099] Step S130: After the test is completed, the robot module picks up the cached unqualified identification cards and puts them into the NG unloading module for unloading, and picks up the cached qualified identification cards and puts them into the loading and unloading machine for unloading.

[0100] In this embodiment, a robot module picks up identification cards from a shuttle module and transfers them to an RFID reader to read RFID information. A testing line then performs a first posture test, screen inspection, product flipping, RFID distance test, second posture inspection, product marking, and product buffering on the identification cards after information reading. After testing, the robot module picks up the buffered identification cards that fail the test and moves them to the NG unloading module for unloading, while the buffered identification cards that pass the test are picked up and moved to the loading and unloading machine for unloading. This integrates identification card function testing and finished product marking and unloading, significantly improving production efficiency and product qualification rate.

[0101] like Figure 21The diagram shows the overall flowchart of the system for testing and marking identification cards in one embodiment. A robot module retrieves three products from a shuttle module and moves them above an RFID reader for information reading. After reading, the three products are placed sequentially into the carrier of a transfer mechanism. The transfer mechanism moves the products under a first shielding test mechanism for first posture detection and screen illumination testing, and uploads the test results. After the shielding test, a visual inspection mechanism detects whether the screen is lit and whether there are any dead pixels, and uploads the inspection results. The transfer mechanism moves the products under a flipping mechanism and flips them 180°, while simultaneously performing an RFID distance test. The test results are uploaded; the transfer mechanism moves the product to the second shielding test mechanism for second posture detection and screen-off test, and uploads the test results; the transfer mechanism moves the product to the laser marking machine for product marking; after marking, the transfer mechanism moves to the initial position and the buffer mechanism moves the tested product to the buffer mechanism for temporary storage; the robot module uses robot vision to detect whether the laser marking effect of the product is qualified, and uploads the detection results; if the product is detected as unqualified, the robot module picks it up and moves it to the NG unloading module for unloading; if the product is detected as qualified, the robot module picks it up and moves it to the loading and unloading machine for unloading.
