Description

Technical Field

[0001] The utility model relates to the technical field of PCB production, in particular to a novel tray automatic board feeding and collecting machine. Background Art

[0002] The electronics industry has experienced rapid development in the 21st century, and the performance of printed circuit boards (PCBs), a key component in its products, has continued to improve, leading to increasingly stringent requirements for PCB manufacturing. PCB manufacturing is a relatively active sector within the contemporary electronic component industry. To meet the automation requirements of the overall PCB production line, a PCB unloader and unloader are installed at the production line's starting point and a PCB collector at its end point to facilitate PCB processing. These unloaders place each PCB horizontally onto the production line's conveyor belt. Once the PCBs have completed processing, the collector removes them from the conveyor belt.

[0003] Chinese utility model patent publication CN113772410B discloses a plate loading machine comprising a frame, a pallet lifting mechanism, an output mechanism, a plate transfer mechanism, and a pallet separation mechanism. The front end of the frame is equipped with multiple parallel loading chambers, which are arranged from bottom to top with a feed station, a retrieving station, and a pallet temporary storage station. The pallet lifting mechanism is installed within the loading chambers and receives pallets loaded with plates from a transport cart and moves them between the feed station, the retrieving station, and the pallet temporary storage station. The output mechanism is installed at the rear end of the frame and interfaces with the main process line. The plate transfer mechanism is also installed at the rear end of the frame, and the pallet separation mechanism is installed at the pallet temporary storage station. This plate loading machine can achieve automated plate loading operations.

[0004] However, the pallet lifting mechanism of the above-mentioned loading machine needs to lift the empty pallet to the temporary storage station for temporary storage after the pallet takes out the board, and then lower the next pallet loaded with boards to the material retrieval station for pallet distribution. During this empty pallet temporary storage process, the splint transplanting mechanism needs to wait until the empty pallet is processed and the next pallet loaded with boards is ready, thereby reducing the overall production efficiency.

[0063] See also Figure 1 、 Figure 2 The present embodiment provides a new type of automatic tray feeding and receiving machine, including a frame 1, a first tray lifting mechanism 2, a first tray transferring mechanism 3, a tray separation conveying mechanism 4, a second tray transferring mechanism 5, a first single tray temporary storage mechanism 6, a first stack tray lifting mechanism 7, a first whole stack tray temporary storage mechanism 8 and a tray discharge conveyor belt 9. The frame 1 is provided with a first tray loading and unloading station, a first tray retrieval station, a tray separation station, a first single tray temporary storage station, a first whole stack tray temporary storage station, a separation station and a tray discharge station.

[0064] The first pallet lifting mechanism 2 is installed at the first tray loading and unloading station. The first pallet lifting mechanism 2 is used to receive a stack of pallets 200 loaded with PCB boards 100 delivered by the loading transport trolley and transport the pallets 200 sequentially to the first tray retrieval station. After all pallets 200 loaded with PCB boards 100 are removed, the first pallet lifting mechanism 2 receives a stack of empty pallets 200 temporarily stored at the first tray retrieval station and transports the stack of empty pallets 200 to the unloading transport trolley. The first pallet transfer mechanism 3 is installed on the frame 1. The first pallet transfer mechanism 3 is used to transport the pallets 200 at the first tray retrieval station to the separation station. The panel separation conveying mechanism 4 is installed at the separation station. The panel separation conveying mechanism 4 is used to cooperate with the first pallet transfer mechanism 3 to separate the PCB boards 100 on the pallets 200 and transport the PCB boards 100 to the panel discharge station. The panel discharge conveyor belt 9 is installed at the panel discharge station. The panel discharge conveyor belt 9 is used to receive the PCB boards 100 delivered by the panel separation conveyor mechanism 4 and transport them to the next process. The second pallet transfer mechanism 5 is mounted on the frame 1. The second pallet transfer mechanism 5 is used to transfer the empty pallet 200 located at the separation station to the first single pallet temporary storage station. The first single pallet temporary storage mechanism 6 is mounted on the first single pallet temporary storage station. The first single pallet temporary storage mechanism 6 is used to receive and temporarily store the empty pallet 200 transferred by the second pallet transfer mechanism 5. The first stack pallet lifting mechanism 7 is mounted on the frame 1. The first stack pallet lifting mechanism 7 is used to transfer the empty pallet 200 temporarily stored in the first single pallet temporary storage station to the first full stack pallet temporary storage station. The first full stack pallet temporary storage mechanism 8 is mounted on the first full stack pallet temporary storage station. The first full stack pallet temporary storage mechanism 8 is used to receive and stack the empty pallets 200 transferred by the first stack pallet lifting mechanism 7.

[0065] Working principle of the casting board:

[0066] During material loading, a loading and transporting trolley (a handcart or an AGV) delivers a stack of trays 200 loaded with PCB boards 100 to the first loading and unloading station. The first tray lifting mechanism 2 receives the stack of trays 200 loaded with PCB boards 100 delivered by the loading and transporting trolley and sequentially delivers the trays 200 to the first unloading station. The first tray transfer mechanism 3 then delivers the trays 200 at the first unloading station to the panel separation conveyor mechanism 4 at the separation station. The panel separation conveyor mechanism 4 cooperates with the first tray transfer mechanism 3 to separate the PCB boards 100 from the trays 200 and deliver them to the panel discharge conveyor belt 9 at the panel discharge station. The panel discharge conveyor belt 9 then transports the PCB boards 100 to the next process step. Next, after the tray 200 at the separation station removes the PCB board 100, the second tray transfer mechanism 5 transports the empty tray 200 to the first single tray temporary storage mechanism 6 at the first single tray temporary storage station for temporary storage. The first stacking tray lifting mechanism 7 then transports the empty tray 200 temporarily stored in the first single tray temporary storage station to the first full tray temporary storage mechanism 8 at the first full tray temporary storage station for stacking. This operation is repeated until the first tray lifting mechanism 2 has removed all the trays 200 loaded with PCB boards 100. The first tray lifting mechanism 2 then receives the full stack of empty trays 200 temporarily stored in the first full tray temporary storage station and transports the full stack of empty trays 200 to the unloading transport vehicle to recycle the full stack of empty trays 200.

[0067] Working principle of receiving board:

[0068] When feeding, the loading and transporting trolley (trolley or AGV trolley) transports the whole stack of empty pallets 200 to the first tray loading and unloading station, and the first pallet lifting mechanism 2 receives the whole stack of empty pallets 200 transported by the loading and transporting trolley, and transports the pallets 200 to the first tray retrieval station in turn. Then, the first pallet transferring mechanism 3 transports the pallet 200 located at the first pallet retrieval station to the panel separation conveying mechanism 4 located at the separation station, and the panel discharge conveyor belt 9 receives the PCB board 100 transported from the next process and transports it to the panel separation conveying mechanism 4. After the PCB board 100 is in place, it is located directly above the pallet 200. The second pallet transferring mechanism 5 drives the pallet 200 to rise to load the PCB board 100, and transports the pallet 200 loaded with the PCB board 100 to the first single pallet temporary storage station for temporary storage on the first single pallet temporary storage mechanism 6. The first stack pallet lifting mechanism 7 then transports the pallet 200 carrying the PCB board 100 temporarily stored in the first single pallet temporary storage station to the first whole stack pallet temporary storage mechanism 8 located at the first whole stack pallet temporary storage station for stacking. The above operation is repeated until all the empty trays 200 received by the first tray lifting mechanism 2 are taken out. Then, the first tray lifting mechanism 2 receives the trays 200 loaded with PCB boards 100 temporarily stored in the first tray stack temporary storage station, and transports the trays 200 loaded with PCB boards 100 to the unloading transport trolley, and recovers the trays 200 loaded with PCB boards 100.

[0069] The new type of automatic tray feeding and receiving machine provided in this embodiment has formed a compact and orderly production process between each workstation and mechanism through reasonable layout design, realizing continuous automatic processing of PCB boards 100 and trays 200 from feeding, separating and discharging to stacking and discharging of trays 200, reducing manual intervention, shortening the production cycle, and thus significantly improving the overall production efficiency; by setting the first tray transferring mechanism 3, the panel separation conveying mechanism 4, the second tray transferring mechanism 5, the first single tray temporary storage mechanism 6, the first stack tray lifting mechanism 7, and the first whole stack tray temporary storage mechanism 8, continuous automatic processing of taking trays, separating panels, and stacking trays is realized, so that the first tray lifting mechanism 2 only needs to convey the trays 200 to the first tray taking station in sequence without performing other operations, thereby reducing waiting time and speeding up the production rhythm.

[0070] See also Figure 1 、 Figure 2In one embodiment, to ensure continuous production, the frame 1 is further equipped with a second tray loading and unloading station, a second tray retrieval station, a second single-tray temporary storage station, and a second full-tray temporary storage station. These stations are arranged sequentially from bottom to top. The novel automatic tray loading and unloading machine also includes a second tray lifting mechanism 10, a second single-tray temporary storage mechanism 11, a second stack of trays lifting mechanism 12, and a second full-tray temporary storage mechanism 13. The second tray lifting mechanism 10 is installed at the second tray loading and unloading station. It is used to receive stacks of trays 200 loaded with PCB boards 100 from the loading transport cart and transport these trays 200 in sequence to the second tray retrieval station. After all trays 200 loaded with PCB boards 100 have been removed, it then receives a stack of empty trays 200 temporarily stored in the second full-tray temporary storage station and transports the stack of empty trays 200 to the unloading transport cart. The second pallet transfer mechanism 5 is also used to transfer pallets 200 located at the second pallet removal station to the separation station. The second pallet transfer mechanism 5 is also used to transfer empty pallets 200 located at the separation station to the second single pallet temporary storage station. A second single pallet temporary storage mechanism 11 is installed at the second single pallet temporary storage station and is used to receive and temporarily store empty pallets 200 transferred by the second pallet transfer mechanism 5. A second stacking pallet lifting mechanism 12 is installed on the frame 1 and is used to transfer empty pallets 200 temporarily stored at the second single pallet temporary storage station to the second stacking pallet temporary storage station. A second stacking pallet temporary storage mechanism 13 is installed at the second stacking pallet temporary storage station and is used to receive and stack empty pallets 200 transferred by the second stacking pallet lifting mechanism 12. Since the operating principles of the second set of stations and mechanisms of the new automatic tray loading and unloading machine are the same as those of the first set of stations and mechanisms, they will not be described again.

[0071] The new automatic tray receiving and loading machine realizes dual-track alternating tray feeding and receiving operations by adding a second set of workstations and mechanisms, allowing the equipment to continuously receive, process and output 200 trays during the production process, reducing waiting time and production interruptions, and further enhancing production continuity.

[0072] See also Figure 3In one embodiment, the first tray transfer mechanism 3 includes a first suction cup assembly 301 for sucking the tray 200, a first suction cup lifting module 302 for driving the first suction cup assembly 301 to rise and fall, and a first suction cup transverse movement module 303 for driving the first suction cup assembly 301 to move laterally. The first suction cup transverse movement module 303 is connected to the frame 1, the first suction cup lifting module 302 is connected to the transverse movement end of the first suction cup transverse movement module 303, and the first suction cup assembly 301 is connected to the lifting end of the first suction cup lifting module 302. The first tray transfer mechanism 3 transfers the tray 200 located at the first tray removal station to the separation station through the cooperation between the first suction cup assembly 301, the first suction cup lifting module 302, and the first suction cup transverse movement module 303.

[0073] See also Figure 4 In one embodiment, the first single-pallet temporary storage mechanism 6 includes two opposed single-pallet temporary storage modules 601. Each single-pallet temporary storage module 601 includes a first telescopic fork 6011 for supporting the pallet 200 and a first telescopic module 6012 for driving the first telescopic fork 6011 to extend and retract. The first telescopic module 6012 is connected to the frame 1, and the first telescopic fork 6011 is connected to the telescopic end of the first telescopic module 6012. When the second pallet transfer mechanism 5 transports the pallet 200 from the separation station to the first single-pallet temporary storage station, the first telescopic modules 6012 of the two single-pallet temporary storage modules 601 simultaneously extend the first telescopic fork 6011, thereby stably and accurately storing the pallet 200 at the first single-pallet temporary storage station. At this point, the second pallet transfer mechanism 5 can return to perform other tasks, while the first single-pallet temporary storage mechanism 6 retains the pallet 200 at the first single-pallet temporary storage station, awaiting subsequent processing or transportation.

[0074] See also Figure 5 In one embodiment, the first pallet stacking temporary storage mechanism 8 includes two pallet stacking temporary storage modules 801 disposed opposite each other. The pallet stacking temporary storage module 801 includes a second telescopic fork 8011 for supporting the pallet 200 and a second telescopic module 8012 for driving the second telescopic fork 8011 to extend and retract. The second telescopic module 8012 is connected to the frame 1, and the second telescopic fork 8011 is connected to the telescopic end of the second telescopic module 8012. When the first pallet stacking lifting mechanism 7 transports the pallet 200 located at the first single pallet temporary storage station to the first pallet stacking temporary storage station, the second telescopic modules 8012 of the two pallet stacking temporary storage modules 801 simultaneously extend the second telescopic forks 8011, thereby stably and accurately stacking the pallet 200 at the second single pallet temporary storage station.

[0075] See also Figure 6In one embodiment, the first stack pallet lifting mechanism 7 includes two oppositely arranged sub-pallet lifting modules 701, the sub-pallet lifting module 701 including a third telescopic fork 7011 for supporting the pallet 200, a third telescopic module 7012 for driving the third telescopic fork 7011 to extend and retract, a first lifting module 7013 for driving the third telescopic fork 7011 to rise and fall, and a second lifting module 7014 for driving the third telescopic fork 7011 to rise and fall. The second lifting module 7014 is connected to the frame 1, the first lifting module 7013 is connected to the lifting end of the second lifting module 7014, the third telescopic module 7012 is connected to the lifting end of the first lifting module 7013, and the third telescopic fork 7011 is connected to the telescopic end of the third telescopic module 7012. The lifting distance of the first lifting module 7013 is equal to the thickness of a pallet 200, and the lifting distance of the second lifting module 7014 is equal to the distance from the first single pallet temporary storage station to the first full stack pallet temporary storage station. In the initial state, the supporting surface of the third telescopic fork 7011 is flush with the bottom surface of the pallet 200 temporarily stored at the bottom of the first pallet stack temporary storage mechanism 8 . When taking the tray, the first stack tray lifting mechanism 7 drives the third telescopic fork 7011 to descend to the first single tray temporary storage station through the second lifting module 7014, and then extends the third telescopic fork 7011 through the third telescopic module 7012 to support the tray 200 located at the first single tray temporary storage station, and the second lifting module 7014 drives the tray 200 to rise again, so that the tray 200 is stacked together with the tray 200 temporarily stored at the bottom of the first whole stack tray temporary storage mechanism 8; then, the first whole stack tray temporary storage mechanism 8 retracts the second telescopic fork 8011 through the second telescopic module 8012, and the first stack tray lifting mechanism 7 drives the whole stack tray 200 to rise again through the first lifting module 7013, and the rising distance is the thickness of one tray 200; finally, the first whole stack tray temporary storage mechanism 8 extends the second telescopic fork 8011 through the second telescopic module 8012 to support the whole stack tray 200. The above operation is repeated until the entire batch of pallets 200 received by the first pallet lifting mechanism 2 is removed.

[0076] The first stack of pallet lifting mechanism 7 set up above can efficiently transport the pallet 200 temporarily stored in the first single pallet temporary storage station to the first whole stack of pallet temporary storage station for stacking by precisely controlling the lifting distance of the first lifting module 7013 and the second lifting module 7014, as well as the telescopic action of the third telescopic module 7012, thereby greatly improving the stacking efficiency of the pallet 200.

[0077] Preferably, the first lifting module 7013 and the second lifting module 7014 are both composed of a combination of a cylinder and a slide rail, which not only reduces the cost but also makes the overall structure more compact.

[0078] See also Figure 7In one embodiment, the panel conveyor mechanism 4 includes a fixed frame 401, a conveyor motor 402, a transmission member 403, and multiple conveyor belt connecting shafts 404 evenly distributed horizontally between the fixed frame 401. The fixed frame 401 is fixed to the frame 1, and the conveyor motor 402 is fixed to the fixed frame 401. The output shaft of the conveyor motor 402 is connected to one end of the conveyor belt connecting shaft 404 via the transmission member 403, driving the conveyor belt connecting shaft 404 to rotate. Rollers 405 are spaced apart on the conveyor belt connecting shaft 404. Pallet positioning and lifting mechanisms 406 are also provided on both sides of the fixed frame 401 to cooperate with the positioning of the pallet 200, ensuring that the pallet 200 is accurately positioned when placed on the panel conveyor mechanism 4. When the PCB separation conveyor mechanism 4 is in operation, the conveyor motor 402 is activated, driving the conveyor belt connecting shaft 404 to rotate synchronously via the transmission member 403. This in turn drives the rollers 405 to rotate synchronously via the conveyor belt connecting shaft 404. The conveyor belt connecting shaft 404, via the rollers 405, transports the PCB boards 100 to the board discharge station. Due to the hollowed-out bottom of the tray 200, when the first tray transfer mechanism 3 places the tray 200 loaded with PCB boards 100 onto the tray positioning and lifting mechanism 406, the rollers 405 lift the PCB boards 100 through the tray 200, separating them from the tray 200. At this point, the highest point of the rollers 405 is above the top surface of the tray 200. The rollers 405 then transport the PCB boards 100 to the board discharge station. When the second tray transfer mechanism 5 arrives at the PCB separation station to retrieve the tray 200, the tray positioning and lifting mechanism 406 lifts the tray 200, allowing the second tray transfer mechanism 5 to successfully retrieve the tray 200. The above-mentioned panel conveying mechanism 4 has a simple structure. It can not only cooperate with the first tray transferring mechanism 3 to separate the PCB board 100 on the tray 200 and convey the separated PCB board 100 to the panel output station, but also enable the second tray transferring mechanism 5 to smoothly obtain the tray 200 after the panel is separated.

[0079] See also Figure 1 、 Figure 2 、 Figure 8 In one embodiment, the new automatic tray loading and unloading machine also includes a lifting mechanism 14 and a first alignment mechanism 15. The lifting mechanism 14 is mounted below the outgoing conveyor belt 9 and is used to lift the PCB board 100 from the outgoing conveyor belt 9. The first alignment mechanism 15 is mounted on the left and right sides of the outgoing conveyor belt 9 and is used to align the left and right sides of the PCB board 100 lifted by the lifting mechanism 14. The installation of the lifting mechanism 14 and the first alignment mechanism 15 allows the equipment to be positioned according to the outgoing board positioning requirements.

[0080] See also Figure 1 、 Figure 2In one embodiment, the new type of automatic tray receiving and delivering machine also includes a tray floating platform 16 and a second alignment mechanism 17. The tray floating platform 16 and the second alignment mechanism 17 are both installed on the first tray loading and unloading station. The tray floating platform 16 is used to place the whole stack of trays 200 transported by the first tray lifting mechanism 2; the second alignment mechanism 17 is used to align the position of the whole stack of trays 200 placed on the tray floating platform 16. After the first tray lifting mechanism 2 receives the whole stack of trays 200 transported by the loading and transporting trolley, it is first placed on the tray 200 floating platform, and then the second alignment mechanism 17 aligns the position of the whole stack of trays 200. After alignment, the tray loading and lifting mechanism then transports the whole stack of trays 200 to the tray retrieval station in sequence. The setting of the tray 200 floating platform and the second alignment mechanism 17 ensures that the tray 200 maintains the correct posture and position during the transmission process, thereby improving the stability and reliability of the overall production line.

[0081] See also Figure 1 、 Figure 2 In one embodiment, the frame 1 is also provided with an NG station and a plating station. The new automatic tray loading and unloading machine also includes a PCB board transfer mechanism 18, an NG fixed platform 19, and a plating transfer platform 20. The PCB board transfer mechanism 18 is mounted on the frame 1, the NG fixed platform 19 is mounted on the NG station, and the plating transfer platform 20 is mounted on the plating station. The NG fixed platform 19 is used to temporarily store unqualified PCB boards 100. The plating transfer platform 20 is used to store plating boards. When the system detects that a PCB board 100 output to the board output station is unqualified, the PCB board transfer mechanism 18 will transport the unqualified PCB board 100 to the NG fixed platform 19 for temporary storage. When a specific process requires a plating board to be added, the system issues a command to the PCB board transfer mechanism 18 to place the plating board stored on the plating transfer platform 20 on the board output station.

[0082] See also Figure 9 In one embodiment, the PCB board transfer mechanism 18 includes a second suction cup assembly 1801 for sucking the PCB board 100, a second suction cup lifting module 1802 for driving the second suction cup assembly 1801 to rise and fall, and a second suction cup transverse movement module 1803 for driving the second suction cup assembly 1801 to move laterally. The second suction cup transverse movement module 1803 is connected to the frame 1, the second suction cup lifting module 1802 is connected to the transverse movement end of the second suction cup transverse movement module 1803, and the second suction cup assembly 1801 is connected to the lifting end of the second suction cup lifting module 1802. The PCB board transfer mechanism 18 realizes the transfer of the PCB board 100 at the unloading station to the NG station, or transfers the accompanying plating board at the accompanying plating station to the unloading station through the cooperation between the second suction cup assembly 1801, the second suction cup lifting module 1802, and the second suction cup transverse movement module 1803.

[0083] It should be noted that, since the second pallet transplanting mechanism 5 has the same structure as the first pallet transplanting mechanism 3, the second pallet lifting mechanism 10 has the same structure as the first pallet lifting mechanism 2, the second single pallet temporary storage mechanism 11 has the same structure as the first single pallet temporary storage mechanism 6, the second stack pallet lifting mechanism 12 has the same structure as the first stack pallet lifting mechanism 7, and the second whole stack pallet temporary storage mechanism 13 has the same structure as the first whole stack pallet temporary storage mechanism 8, the present utility model does not repeat the specific structure and working principle of the second pallet transplanting mechanism 5, the second pallet lifting mechanism 10, the second single pallet temporary storage mechanism 11, the second stack pallet lifting mechanism 12 and the second whole stack pallet temporary storage mechanism 13.

[0084] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.

[0085] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
