Description

Technical Field

[0001] The present invention relates to the field of electronic manufacturing technology, and in particular to a MES automatic loading and unloading storage PCB board detection laser code scanning production line. Background Art

[0002] The rapid development of the electronics manufacturing industry has placed higher demands on automation, information technology, and intelligent manufacturing in the production of printed circuit boards (PCBs). Traditional loading and unloading and inspection methods in PCB production are inefficient and error-prone, making them unable to meet the demands of modern intelligent manufacturing. Existing production lines typically utilize semi-automated equipment, but loading and unloading, storage, inspection, and code scanning still require external intervention, limiting production efficiency and creating risks such as PCB scratches and false detection.

[0003] Currently, some companies are attempting to introduce MES for production management. However, existing MES systems lack integration with automated equipment, particularly for automated loading and unloading, precise positioning, and laser barcode scanning of PCB boards. Furthermore, traditional inspection equipment often relies on a single sensor or vision system, making it difficult to address the multi-dimensional quality control of PCB boards, impacting accuracy and consistency.

One end of the transfer mechanism 81 is connected to the code scanning mechanism 9 , and the other end is connected to the first guide rail 21 and / or the second guide rail 31 .

[0025] The initial position of the feeding mechanism 1 can be connected to a conveying structure that is consistent with the structure of the conveying mechanism 4. The conveying mechanism 4 and the conveying structure can enable the material placed in the material tray to be quickly loaded and unloaded together with the material tray, which can be beneficial to improving the integration of the whole machine and improving the detection rate. One side of the feeding channel of the feeding mechanism 1 is connected to a testing mechanism 11 for performing electrical testing on the material in the material tray. When the detection is correct, the material will be transported to the next stage, and the material with problems in the test or even failed the test will be transported to the sorting mechanism 13 by the conveying mechanism 12. The conveying mechanism 12 can be a guide rail with a clamping arm structure with a lifting function, which can quickly transfer materials without affecting the work of the testing mechanism 11 and the loading of the feeding mechanism 1. The sorting mechanism 13 can be used for secondary detection of materials and sorting the materials according to the damage status of the materials. It can improve the space utilization of the entire machine while being beneficial to the subsequent separate processing of materials, ensuring the testing accuracy of the entire process and the recycling efficiency of defective products.

[0026] The feeding mechanism 1 is connected to the first guide rail 21 of the marking processing mechanism 2. The laser coding mechanism 22 is connected to the side of the first guide rail 21 to ensure the stability of coding, and is provided with an XY movable module and a lifting unit relative to the first guide rail 21. The lifting unit can facilitate the laser coding mechanism 22 to adjust the distance between the laser head and the material tray according to the height of the material tray. The XY movable module can improve the stability of laser coding. The scanning and verification mechanism 23 is located between the laser coding mechanism 22 and the first guide rail 21, and is provided with a movable detection track relative to the first guide rail 21, which is used to adjust the position of the scanning detection laser after the coding is completed so that the coding status of the material can be detected at the first time, which is beneficial to improve the detection accuracy and detection rate, and ensure the effect of laser coding. The laser coding mechanism 22 can also be provided with a dust suction component relative to the first guide rail 21. The dust suction component can ensure the cleanliness of the first guide rail 21, reduce the wear of the first guide rail 21, effectively increase the service life of the whole machine, and improve the user experience.

[0027] The unloading mechanism 3 receives and unloads materials through the second guide rail 31. A detection mechanism 32 is connected to one side of the second guide rail 31 to detect the materials, so as to avoid problems in the processing of the materials in the previous steps. After the detection is completed, the materials will be received by the transfer mechanism 5. The transfer mechanism 5 can place the materials in the NG structure 6 or the unloading module 7 according to the detection results of the detection mechanism 32. The NG structure 6 or the unloading module 7 are arranged in sequence along the transfer mechanism 5, which can realize efficient material transfer and improve the detection efficiency of the whole machine. After all the materials are transferred from the material tray, the remaining empty tray will continue to move on the second guide rail 31 and be recovered by the conveying mechanism 4, which can ensure the high integration of various parts of the whole machine and is conducive to improving the material processing rate and detection rate of the whole machine.

[0028] The docking mechanism 8 can be located between the identification processing mechanism 2 and the unloading mechanism 3 to connect the two mechanisms, or it can be connected after the unloading mechanism 3 to detect the material in the unloading module 7. The docking mechanism 8 structurally includes a transfer mechanism 81 for transferring the material from the first guide rail 21 or the unloading module 7 and a scanning mechanism connected to the transfer mechanism 5 for scanning and detecting the material. The transfer mechanism 81 can be set as a transfer mechanism relative to the first guide rail 21 or the unloading module 7. The transfer mechanism can use the clamps and guide rails to transfer the material to the guide rail. The transfer mechanism 81 and the guide rail are aligned. The transfer mechanism 81 can be used to take the material for inspection and then re-convey the material to the guide rail. The material can be repeatedly transferred and reset or transferred to the next processing and inspection mechanism. The docking mechanism 8 can be used as a transfer module between different mechanisms through the above structure, which can effectively improve the integration of the whole machine, and can enable the unloaded materials to complete laser coding, electrical testing, code scanning detection and other steps, thereby effectively ensuring the quality of the materials.

[0029] See also Figures 7 and 8 The scanning mechanism 9 is provided with an alignment guide rail 91 relative to the transfer mechanism 81, and the alignment guide rail 91 is provided with a loading and unloading assembly 92 arranged along the extension direction of the alignment guide rail 91; The transfer mechanism 81 is provided with a loading structure 82 and a unloading structure 83 relative to the loading and unloading assembly 92 .

[0030] The transfer mechanism 81 is provided with a loading structure 82 and a unloading structure 83 relative to the code scanning mechanism 9, so that the material is transported to the code scanning mechanism 9 under the action of the loading structure 82, and after the code scanning inspection is completed, it can be transported back to other testing and processing mechanisms by the unloading structure 83, so that the docking mechanism 8 can be used to quickly take over other mechanisms and serve as a transit for other mechanisms to ensure the processing rate of the whole machine. In order to cooperate with the loading structure 82 and the unloading structure 83, the code scanning mechanism 9 is provided with a positioning guide rail 91 and a loading and unloading assembly 92.

[0031] In a feasible embodiment, the loading structure 82 and the unloading structure 83 are arranged side by side, and guide rails and clamps are provided on the two structures. The terminals of the clamps correspond to different positions of the docking rails. The scanning mechanism 9 can load the material placed on one side of the docking rail to the scanning detection point of the scanning mechanism 9 through the loading and unloading assembly 92. When the detection is completed, it can be transported to the docking position of the unloading structure 83 through the loading and unloading assembly 92, so that the material can be quickly detected.

[0032] See also Figures 7 and 8 The feeding structure 82 and the unloading structure 83 are spaced apart in the vertical direction, and the transfer mechanism 81 is provided with an adjustment mechanism 84 relative to the feeding structure 82 and the unloading structure 83; The adjusting mechanism 84 includes a moving structure 85, a lifting structure 86 and a clamping structure 87. The moving structure 85 is arranged along the extension direction of the feeding structure 82. The bottom of the lifting structure 86 is connected to the moving structure 85. The lifting structure 86 is driven and connected to the clamping structure 87. The clamping structure 87 is connected to the alignment guide rail 91.

[0033] In another feasible embodiment, the loading structure 82 and the unloading structure 83 are arranged up and down, and an adjusting mechanism 84 is provided at the end of the loading and unloading structures 83. The adjusting mechanism 84 can be moved along the driving direction of the loading and unloading structures 83 through the moving structure 85. The clamping structure 87 in the adjusting mechanism 84 can move up and down under the action of the lifting structure 86. The alignment guide rail 91 can be located below the loading and unloading structures 83. With the mutual cooperation of the adjusting mechanism 84, it can ensure that the material is efficiently and stably delivered to the alignment guide rail 91, and the material can be quickly recovered after the code scanning detection is completed, which can effectively improve the speed of the entire testing process.

[0034] See also Figure 7 The upper and lower material components 92 include a feeding structure and a discharging structure. The feeding structure is connected to the side of the clamping structure 87 away from the alignment guide rail 91. The feeding structure is provided with a feeding push rod toward the alignment guide rail 91. The discharge structure is connected to the alignment guide rail 91 , and a discharge push rod is provided along the direction from the alignment guide rail 91 to the clamping structure 87 .

[0035] In another feasible embodiment, the alignment guide rail 91 is located between the loading structure 82 and the unloading structure 83. In order to enable the adjustment mechanism 84 to feed / take materials quickly and stably, the structure of the upper and lower loading and unloading components 92 may include a feeding structure and a discharging structure. The clamping structure 87 is located between the alignment rail and the feeding structure. The feeding structure is generally arranged on the machine table and is arranged toward the alignment guide rail 91. The feeding push rod provided in the feeding structure can pass through the clamping cavity of the clamping structure 87 to push the material into the alignment guide rail 91. After the test is completed, the discharging push rod of the discharging structure can push the material back into the clamping cavity of the clamping structure 87, which can facilitate the transfer of the material to the unloading structure 83 for unloading.

[0036] In order to improve the test efficiency, the storage frame generally moves in the upper and lower material structures 83, and multiple partition layers are provided in the frame. Each partition layer is provided with a material / tray. The clamping structure 87 can clamp the outer periphery of the frame and move up and down along the alignment guide rail 91 under the action of the lifting structure 86. When the partition layer in the frame is facing the alignment guide rail 91, the feed push rod drives the material / tray into the code scanning mechanism 9 for code scanning detection. After the detection is completed, the material / tray is pushed back into the partition by the discharge push rod, and the lifting structure 86 rises / falls so that the other partition layer is facing the alignment guide rail 91. Through this structure, the test efficiency can be effectively improved and the stability of material transportation can be guaranteed.

[0037] See also Figure 1 The sorting mechanism 13 includes a visual inspection component 14, a collecting mechanism 15 and a moving mechanism 16. The visual inspection component 14 is arranged near the feeding mechanism 1 and is connected to the end of the transport mechanism 12 away from the testing mechanism 11. The visual inspection component 14 is provided with a detection camera; One end of the moving mechanism 16 is connected to the visual inspection assembly 14 , and the other end is connected to the collecting mechanism 15 .

[0038] The sorting mechanism 13 is provided with a visual inspection component 14 for receiving and transferring materials transferred from the feeding mechanism 1. The visual inspection component 14 is provided with a detection camera for secondary judgment of the materials that failed the test at the testing mechanism 11. The damage state of the materials is optically detected by the camera, which can facilitate the subsequent recovery and processing of defective products. The visual inspection component 14 serves as a transfer table and is also connected to the moving mechanism 16. After the inspection is completed, the materials will be moved to the collecting mechanism 15 for push-plate recovery, which can help improve space utilization and facilitate the recovery of the waste materials themselves.

[0039] See also Figure 1 The collecting mechanism 15 is provided with a first collecting assembly and a second collecting assembly at intervals along the moving direction of the moving mechanism 16. The moving mechanism 16 is used to place the materials into the first collecting assembly or the second collecting assembly according to the different detection structures of the detection camera.

[0040] The collecting mechanism 15 can be provided with multiple groups, which can at least include a first collecting assembly for collecting slightly damaged materials and a second collecting assembly for collecting severely damaged materials. The moving mechanism 16 itself can be a swing arm structure, and two clamps are provided relative to the three stations of the first collecting assembly, the second collecting assembly, and the visual inspection assembly 14. Through the swing arm structure, the material can be transferred from the visual inspection assembly 14 to the first collecting assembly first. If the material needs to be transferred to the second collecting assembly, another clamp will transfer the material synchronously the next time the material is taken. Through the above structure, the high integration of the whole machine can be effectively guaranteed.

[0041] The moving mechanism 16 can also be two clamping claws with lifting functions that run synchronously on the guide rail, which can play the same function as the swing arm structure, effectively improving the space utilization of the machine and ensuring the recovery efficiency of defective products.

[0042] See also Figures 3 and 4 The NG structure 6 includes a collecting bracket 61, a collecting track provided on the top of the collecting bracket 61, and a collecting frame 63 provided at one end of the collecting bracket 61 and docked with the collecting channel 62. A push rod module is provided on the side of the collecting channel 62 away from the collecting frame 63 and facing the collecting frame 63. A lifting module is vertically provided in the collecting bracket 61 and connected to the bottom of the collecting frame 63 for driving the collecting frame 63 to rise and fall for stacking and storage. The blanking module 7 and the NG structure 6 have the same structure.

[0043] The NG structure 6 for recovering defective products at the unloading mechanism 3 may structurally include a collecting bracket 61, a collecting frame 63, and a lifting module. A plurality of partitions are provided in the vertical direction in the collecting frame 63. The lifting module is connected to the collecting frame 63. When the material is unloaded, it can be unloaded onto the collecting track on the collecting bracket 61. The material will be between the push rod module and the collecting frame 63. The material is pushed into the partition by the push rod module. The collecting module cooperates with the push rod module to quickly stack the material and fill it in the collecting frame 63, which can facilitate the recovery of defective products.

[0044] In one embodiment, the structure of the unloading module 7 is exactly the same as that of the NG structure 6. Qualified materials will be collected by the collection frame 63 and transferred by the transfer structure to the docking mechanism 8. After being clamped by the clamping structure 87 of the docking mechanism 8 and tested in batches, the materials in the collection frame 63 will be sent to the unloading place by the unloading structure 83, which can improve the integration of the whole machine and make the different bodies closely connected.

[0045] See also Figures 3 to 5 The unloading module 7 includes a supporting tray 71, a lifting module arranged at the bottom of the supporting tray 71, and a disc conveyor belt 73 located below the transfer mechanism 5 and arranged perpendicular to the transfer mechanism 5. The supporting tray 71 is connected to one side of the disc conveyor belt 73 and is provided with an opening 72 for the disc conveyor belt 73 to pass through at a position relative to the disc conveyor belt 73.

[0046] In another embodiment, the structure of the unloading module 7 is different from the above-mentioned NG structure 6. Functionally, the unloading module 7 includes a support tray 71, a lifting module for driving the tray to move up and down, and a disc conveyor belt 73 for conveying the tray filled with materials to unload the materials. The support tray 71 is connected to one side of the disc conveyor belt 73 and is provided with an opening 72 relative to the disc conveyor belt 73. When the tray is full of materials and needs to be unloaded, the lifting module descends, and the support tray 71 moves down through the disc conveyor belt 73. The tray will remain on the disc conveyor belt 73 and be transported away by the disc conveyor belt 73. This structure can also ensure that the materials are unloaded and closed quickly, which is conducive to improving the detection efficiency.

[0047] See also Figure 3 The transfer mechanism 5 is also connected to an upper disc assembly 51. The structure of the upper disc assembly 51 is the same as that of the blanking module 7. The conveying direction of the supply disc conveyor belt of the upper disc assembly 51 is opposite to the conveying direction of the supply disc conveyor belt of the blanking module 7.

[0048] The transfer mechanism 5 is also connected to an upper disc assembly 51. The transfer mechanism 5 can cooperate with the upper disc assembly 51 to load empty material trays to the unloading module 7, which can help to increase the loading rate. The supply tray conveyor belt of the upper disc assembly 51 can simultaneously load multiple stacked empty material trays toward the support tray 71, which can effectively improve the linkage of the entire machine.

[0049] A driving motor can be set on both sides of the transfer mechanism 5, and the two driving motors respectively drive a suction cup / grip for transferring materials or material trays. The two suction cups / grips can be controlled independently, which can effectively ensure the loading rate of the empty material tray. The suction cups / grips on both sides can share a moving track, which can reduce the size of the entire machine and effectively improve the user experience.

At least two unloading tracks are provided at intervals in the vertical direction at one end of the recovery bracket 41 away from the second guide rail 31.

[0051] The conveying mechanism 4 is used to recycle the material trays after the material is taken out. The conveying mechanism 4 itself structurally includes a recovery bracket 41. The recovery bracket 41 can be raised and lowered by a docking component 42. A conveying track 43 is provided in the recovery bracket 41. The conveying track 43 can be connected to a recovery frame 44 with multiple partition layers arranged in the vertical direction. Under the action of the docking component 42, different partitions can be connected to the second guide rail 31 in turn. When the recovery frame 44 is stacked and filled with empty material trays, the conveying track 43 will transport the recovery frame 44 to the unloading track connected to the other side of the conveying mechanism 4 for unloading.

[0052] Multiple unloading tracks can be set along the height direction. Different unloading tracks can align the recovery frame 44 and the corresponding unloading tracks under the action of the docking component 42. Different unloading tracks can be connected to different mechanisms, which is beneficial to improve the linkage of the whole machine and the degree of automation of the whole machine. In addition, a conveying mechanism 4 with the same structure as that of the present application can also be connected to the end of the loading mechanism 1 for high-efficiency loading. Through the above structure, the integration of the whole machine can be improved, the body detection efficiency can be effectively improved, the quality of the unloading materials can be guaranteed, and the user experience can be effectively improved.
