[0059] Among them, the feeding tray lifting mechanism 2 is installed at the feeding tray station. The feeding tray lifting mechanism 2 is used to receive the stack of trays 100 carrying the PCB boards 200 transported by the feeding transport trolley, and convey the stack of trays 100 to the tray temporary storage station. The tray temporary storage mechanism 3 is installed at the tray temporary storage station. The tray temporary storage mechanism 3 is used to receive and temporarily store the stack of trays 100 conveyed by the feeding tray lifting mechanism 2. The tray separating and lifting mechanism 4 is installed on the rack 1. The tray separating and lifting mechanism 4 is used to cooperate with the tray temporary storage mechanism 3 to separate the tray 100 at the bottom of the tray temporary storage mechanism 3 and convey it to the tray taking station. The tray fork mechanism 5 is installed on the rack 1. The tray fork mechanism 5 is used to convey the tray 100 at the tray taking station to the transfer station. The tray transplanting mechanism 6 is installed on the rack 1. The tray transplanting mechanism 6 is used to sequentially convey the tray 100 at the transfer station to the separating station and the discharging tray station. The PCB board conveying mechanism 7 is installed at the separating station. The PCB board conveying mechanism 7 is used to cooperate with the tray transplanting mechanism 6 to separate the PCB boards 200 on the tray 100 and convey the PCB boards 200 to the PCB board discharging station. The PCB board discharging conveyor belt 8 is installed at the PCB board discharging station. The PCB board discharging conveyor belt 8 is used to receive the PCB boards 200 conveyed by the PCB board conveying mechanism 7 and convey them to the next process. The tray stacking and lifting mechanism 9 is installed at the discharging tray station. The tray stacking and lifting mechanism 9 is used to receive and stack the empty trays 100 conveyed by the tray transplanting mechanism 6. The discharging tray transfer conveyor belt 10 is installed below the tray stacking and lifting mechanism 9. The discharging tray transfer conveyor belt 10 is used to receive the trays 100 stacked by the tray stacking and lifting mechanism 9 and convey them to the discharging tray temporary storage station. The discharging tray temporary storage conveyor belt 11 is installed at the discharging tray temporary storage station. The discharging tray temporary storage conveyor belt 11 is used to receive and temporarily store the stack of trays 100 conveyed by the discharging tray transfer conveyor belt 10. The discharging tray lifting mechanism 12 is installed on both sides of the discharging tray temporary storage conveyor belt 11. The discharging tray lifting mechanism 12 is used to convey the stack of trays 100 temporarily stored on the discharging tray temporary storage conveyor belt 11 to the discharging transport trolley.

[0060] PCB board discharging working principle:

[0061] During feeding, the loading and transporting trolley (handcart or AGV trolley) conveys the whole stack of pallets 100 carrying PCB boards 200 to the tray loading station. The tray loading lifting mechanism 2 receives the whole stack of pallets 100 carrying PCB boards 200 conveyed by the loading and transporting trolley and conveys the whole stack of pallets 100 to the pallet temporary storage mechanism 3 at the pallet temporary storage station for temporary storage. At this time, the loading and transporting trolley can convey the next batch of whole stacks of pallets 100 carrying PCB boards 200 to the tray loading station, and then the tray loading lifting mechanism 2 receives and temporarily stores the next batch of whole stacks of pallets 100 carrying PCB boards 200. After all the pallets 100 on the pallet temporary storage mechanism 3 are taken away by the pallet fork mechanism 5, the tray loading lifting mechanism 2 can quickly convey the temporarily stored next batch of whole stacks of pallets 100 carrying PCB boards 200 to the pallet temporary storage mechanism 3, thus avoiding the problem of production line interruption and improving the overall production efficiency.

[0062] Then, the pallet separating and lifting mechanism 4 cooperates with the pallet temporary storage mechanism 3 to separate the pallet 100 at the bottom of the pallet temporary storage mechanism 3 and convey it to the pallet taking station for the pallet fork mechanism 5 to take the pallet. After the pallet fork mechanism 5 takes the pallet, it conveys the pallet 100 to the transfer station for the pallet transplanting mechanism 6 to take the pallet. After the pallet transplanting mechanism 6 takes the pallet, it conveys the pallet 100 to the board separating and conveying mechanism 7 at the separating station. The board separating and conveying mechanism 7 cooperates with the pallet transplanting mechanism 6 to separate the PCB boards 200 on the pallet 100 and convey the PCB boards 200 to the board output conveyor belt 8 at the board output station. The board output conveyor belt 8 further conveys the PCB boards 200 to the next process.

[0063] During discharging, after the pallet 100 at the separating station takes out the PCB boards 200, the pallet transplanting mechanism 6 conveys the empty pallet 100 to the pallet stacking and lifting mechanism 9 at the tray discharging station for stacking. After the pallet stacking and lifting mechanism 9 stacks up the empty pallets 100, it conveys the whole stack of empty pallets 100 to the tray discharging transfer conveyor belt 10. The tray discharging transfer conveyor belt 10 further conveys the whole stack of empty pallets 100 to the tray discharging temporary storage conveyor belt 11 at the tray discharging temporary storage station for temporary storage. Before the next stack of empty pallets 100 arrives, the tray discharging lifting mechanism 12 jacks up the whole stack of empty pallets 100 temporarily stored on the tray discharging temporary storage conveyor belt 11. The unloading and transporting trolley (handcart or AGV trolley) enters the tray discharging temporary storage station to receive the whole stack of empty pallets 100 and then exits the tray discharging temporary storage station.

[0064] Principle of board collection:

[0065] During feeding, the loading and transporting trolley conveys a stack of empty pallets 100 to the pallet feeding station. The pallet feeding lifting mechanism 2 receives the stack of empty pallets 100 conveyed by the loading and transporting trolley and conveys the stack of pallets 100 to the pallet temporary storage mechanism 3 at the pallet temporary storage station for temporary storage. At this time, the loading and transporting trolley can convey the next stack of empty pallets 100 to the pallet feeding station, and then the pallet feeding lifting mechanism 2 receives and temporarily stores the next stack of empty pallets 100. After all the pallets 100 on the pallet temporary storage mechanism 3 are taken away by the pallet fork mechanism 5, the pallet feeding lifting mechanism 2 can quickly convey the temporarily stored next stack of empty pallets 100 to the pallet temporary storage mechanism 3, thus avoiding the problem of production line interruption and improving the overall production efficiency.

[0066] Then, the pallet separating and lifting mechanism 4 cooperates with the pallet temporary storage mechanism 3 to separate the pallet 100 at the bottom of the pallet temporary storage mechanism 3 and convey it to the pallet taking station for the pallet fork mechanism 5 to take the pallet. After the pallet fork mechanism 5 takes the pallet, it conveys the pallet 100 to the transfer station for the pallet transplanting mechanism 6 to take the pallet. After the pallet transplanting mechanism 6 takes the pallet, it conveys the pallet 100 to the board separating and conveying mechanism 7 at the separating station. The outgoing board conveyor belt 8 receives the PCB boards 200 conveyed from the next process and conveys them to the board separating and conveying mechanism 7. After the PCB boards 200 are in place, they are directly above the pallet 100.

[0067] During discharging, the pallet transplanting mechanism 6 drives the pallet 100 to rise to load the PCB boards 200 and conveys the pallet 100 loaded with PCB boards 200 to the pallet stacking and lifting mechanism 9 at the pallet discharging station for stacking. After the pallet stacking and lifting mechanism 9 stacks the pallets 100 loaded with PCB boards 200, it conveys the stack of pallets 100 loaded with PCB boards 200 to the outgoing pallet transfer conveyor belt 10, and the outgoing pallet transfer conveyor belt 10 further conveys the stack of pallets 100 loaded with PCB boards 200 to the outgoing pallet temporary storage conveyor belt 11 at the outgoing pallet temporary storage station for temporary storage. Before the next stack of pallets 100 loaded with PCB boards 200 arrives, the outgoing pallet lifting mechanism 12 jacks up the stack of pallets 100 loaded with PCB boards 200 temporarily stored on the outgoing pallet temporary storage conveyor belt 11, and the unloading and transporting trolley enters the outgoing pallet temporary storage station to receive the stack of pallets 100 loaded with PCB boards 200 and then exits the outgoing pallet temporary storage station.

[0068] The Tray automatic loading and unloading machine provided in this embodiment forms a compact and orderly production process among various workstations and mechanisms through reasonable layout design, realizing the continuous automatic processing of PCB boards 200 and trays 100 from feeding, temporary storage, tray separation, board separation, board output to the stacking and discharging of trays 100, reducing manual intervention and shortening the production cycle, thus significantly improving the overall production efficiency. By setting the tray separation lifting mechanism 4, the trays 100 temporarily stored in the tray temporary storage mechanism 3 can be separated one by one. Moreover, since the tray separation operation of the tray 100 does not require the cooperation of the tray feeding lifting mechanism 2, after the tray feeding lifting mechanism 2 delivers a batch of trays 100 to the tray temporary storage mechanism 3, it can directly receive and temporarily store the next batch of trays 100, realizing the rapid transportation of the next batch of trays 100 to the tray temporary storage mechanism 3, thereby avoiding the problem of production line interruption and improving the overall production efficiency. By setting the out-feed transfer conveyor belt 10 to connect the tray stacking lifting mechanism 9 and the out-feed temporary storage conveyor belt 11, the out-feed temporary storage conveyor belt 11 can smoothly receive and temporarily store the trays 100 stacked by the tray stacking lifting mechanism 9, realizing the orderly management and scheduling of the recycling of the trays 100.

[0069] Please refer to Figure 3 , in one embodiment, the tray feeding lifting mechanism 2 includes two relatively arranged tray feeding lifting modules 201, and a tray feeding lifting fork 2011 for holding the tray 100 is arranged at the lifting end of the tray feeding lifting module 201. The two relatively arranged tray feeding lifting modules 201 can provide more stable support and lifting force, ensuring that when receiving and transporting a stack of trays 100, the trays 100 can be smoothly and safely lifted and lowered, reducing the risk of the trays 100 tilting or falling, and improving the reliability and safety of the entire production process.

[0070] Please refer to Figure 3 , in one embodiment, the tray temporary storage mechanism 3 includes two relatively arranged tray temporary storage modules 301, and the two tray temporary storage modules 301 are respectively arranged at the upper ends of the two tray feeding lifting modules 201. The tray temporary storage module 301 includes a first telescopic fork 3011 for holding the tray 100, a first telescopic module 3012 for driving the first telescopic fork 3011 to extend and retract. The first telescopic module 3012 is connected to the corresponding tray feeding lifting module 201, and the first telescopic fork 3011 is connected to the telescopic end of the first telescopic module 3012. By respectively arranging the two tray temporary storage modules 301 at the upper ends of the two tray feeding lifting modules 201, the space in the vertical direction of the equipment is fully utilized, enabling the equipment to store more trays 100 in a limited space and improving the space utilization rate of the production line.

[0071] Please refer to Figure 4, in one embodiment, the sub-tray lifting mechanism 4 includes two relatively arranged sub-tray lifting modules 401. The sub-tray lifting module 401 includes a second telescopic fork 4011 for supporting the tray 100, a second telescopic module 4012 for driving the second telescopic fork 4011 to extend and retract, a first lifting module 4013 for driving the second telescopic fork 4011 to lift, and a second lifting module 4014 for driving the second telescopic fork 4011 to lift. The second lifting module 4014 is connected to the frame 1. The lifting end of the first lifting module 4013 is connected to the lifting end of the second lifting module 4014. The second telescopic module 4012 is connected to the lifting end of the first lifting module 4013. The second telescopic fork 4011 is connected to the telescopic end of the second telescopic module 4012. The lifting distance of the first lifting module 4013 is equal to the thickness of one tray 100. The lifting distance of the second lifting module 4014 is equal to the distance from the tray 100 stored at the bottom of the tray storage mechanism 3 to the tray picking station. In the initial state, the support surface of the second telescopic fork 4011 is flush with the bottom surface of the tray 100 stored at the bottom of the tray storage mechanism 3. When dividing the trays, the sub-tray lifting mechanism 4 extends the second telescopic fork 4011 to the bottom surface of the lowermost tray 100 through the second telescopic module 4012 to support the entire stack of trays 100. Then, the tray storage mechanism 3 retracts the first telescopic fork 3011 through the first telescopic module 3012. The sub-tray lifting mechanism 4 then drives the entire stack of trays 100 to rise through the first lifting module 4013 by a distance equal to the thickness of one tray 100. Then, the tray storage mechanism 3 extends the first telescopic fork 3011 through the first telescopic module 3012 to support the second-to-last tray 100. Finally, the sub-tray lifting mechanism 4 drives the lowermost tray 100 to descend to the tray picking station through the second lifting module 4014 to wait for the tray fork mechanism 5 to pick it up. Repeat the above operations in a loop until all the trays 100 stored in the tray storage mechanism 3 are taken away.

[0072] For the sub-tray lifting mechanism 4 arranged as above, by precisely controlling the lifting distances of the first lifting module 4013 and the second lifting module 4014, and the telescopic movement of the second telescopic module 4012, it can efficiently separate the lowermost single tray 100 in the tray storage mechanism 3 and send it to the tray picking station, greatly improving the efficiency of tray 100 handling.

[0073] Preferably, both the first lifting module 4013 and the second lifting module 4014 are composed of a combination of a cylinder and a slide rail, which not only has a low cost, but also can make the overall structure more compact.

[0074] Please refer to Figure 5, in one embodiment, the pallet fork mechanism 5 includes a fork assembly 501 for acquiring the pallet 100, a fork telescoping module 502 for driving the fork assembly 501 to telescope, and a fork lifting module 503 for driving the fork assembly 501 to lift. The fork lifting module 503 is connected to the frame 1, the fork telescoping module 502 is connected to the lifting end of the fork lifting module 503, and the fork assembly 501 is connected to the telescoping end of the fork telescoping module 502. Through the telescoping and lifting actions of the fork assembly 501, the pallet fork mechanism 5 can quickly and accurately acquire the pallet 100 at the pallet picking station and transport it to the transfer station, and can complete efficient operations in a relatively small space, so as to maximize the utilization of limited space resources and make the overall structure of the equipment more compact.

[0075] Specifically, the fork assembly 501 includes two forks 5011 arranged side by side at intervals. The ends of the two forks 5011 are connected to the telescoping end of the fork telescoping module 502, and a first positioning block 5012 for cooperating with and positioning the pallet 100 is provided on the top of the fork 5011. The setting of the first positioning block 5012 realizes the precise positioning of the pallet 100 during the handling process, helps to reduce the shaking and offset of the pallet 100 during the handling process, and ensures that the pallet 100 can be accurately and stably placed at the target position.

[0076] In addition, the distance between the two forks 5011 is greater than the width of the board separating and conveying mechanism 7, and the board separating and conveying mechanism 7 is arranged between the two forks 5011. The above setting can not only enable the two forks 5011 to move smoothly above or below the board separating and conveying mechanism 7 under the drive of the fork lifting module 503 to transport the pallet 100 at the pallet picking station to the transfer station, but also make the overall structure of the equipment more compact.

[0077] Please refer to Figure 6 , in one embodiment, the pallet transplanting mechanism 6 includes a first suction cup assembly 601 for sucking the pallet 100, a first suction cup lifting module 602 for driving the first suction cup assembly 601 to lift, and a first suction cup transverse movement module 603 for driving the first suction cup assembly 601 to move transversely. The first suction cup transverse movement module 603 is connected to the frame 1, the first suction cup lifting module 602 is connected to the transverse movement end of the first suction cup transverse movement module 603, and the first suction cup assembly 601 is connected to the lifting end of the first suction cup lifting module 602. The pallet transplanting mechanism 6 realizes the sequential transportation of the pallet 100 at the transfer station to the separation station and the pallet discharging station through the cooperation among the first suction cup assembly 601, the first suction cup lifting module 602, and the first suction cup transverse movement module 603.

[0078] Please refer to Figure 7 , Figure 8, in one embodiment, the board separation and conveying mechanism 7 includes a fixing frame 701, a conveying motor 702, a transmission member 703, and multiple conveyor belt connecting shafts 704 horizontally and evenly distributed between the fixing frames 701. The fixing frame 701 is fixed to the machine frame 1, the conveying motor 702 is fixed to the machine frame 1, and the output shaft of the conveying motor 702 is connected to one end of the conveyor belt connecting shaft 704 through the transmission member 703 and drives the conveyor belt connecting shaft 704 to rotate. Rollers 705 are spaced apart on the conveyor belt connecting shaft 704, and the rollers 705 are used to support and convey the PCB board 200. Second positioning blocks 706 that cooperate with the tray 100 for positioning are provided at the four corners of the top of the fixing frame 701 to ensure accurate positioning when the tray 100 is placed. When the board separation and conveying mechanism 7 operates, the conveying motor 702 is started, and the conveyor belt connecting shaft 704 is driven to rotate synchronously through the transmission member 703. Then, the rollers 705 are driven to rotate synchronously through the conveyor belt connecting shaft 704, and the PCB board 200 is conveyed to the board output station by the conveyor belt connecting shaft 704 through the rollers 705. Since the bottom of the tray 100 is provided with a hollow, when the tray transplanting mechanism 6 places the tray 100 carrying the PCB board 200 on the second positioning blocks 706 at the top of the fixing frame 701, the rollers 705 will lift the PCB board 200 through the tray 100, separating the PCB board 200 from the tray 100. At this time, the highest point of the rollers 705 is higher than the top surface of the tray 100, and then the rollers 705 convey the PCB board 200 to the board output station. The above-described board separation and conveying mechanism 7 has a simple structure and can not only cooperate with the tray transplanting mechanism 6 to separate the PCB board 200 on the tray 100 but also convey the separated PCB board 200 to the board output station.

[0079] Please refer to Figure 1 , Figure 2 , Figure 9 , in one embodiment, the Tray automatic board loading and unloading machine further includes a lifting mechanism 13 and a first board aligning mechanism 14.

The PCB board transfer mechanism 15 is installed on the rack 1, the NG fixing platform 16 is installed on the NG station, and the co-plating transfer platform 17 is installed on the co-plating station. The NG fixing platform 16 is used to temporarily store unqualified PCB boards 200. The co-plating transfer platform 17 is used to store co-plating boards. When the system detects that the PCB board 200 output to the board unloading station is unqualified, the PCB board transfer mechanism 15 will convey the unqualified PCB board 200 to the NG fixing platform 16 for temporary storage. When a specific process requires replenishing co-plating boards, the system issues an instruction to let the PCB board transfer mechanism 15 place the co-plating boards stored on the co-plating transfer platform 17 onto the board unloading station.

[0081] Please refer to Figure 10 , in one embodiment, the PCB board transfer mechanism 15 includes two second suction cup assemblies 1501 arranged side by side at intervals for sucking the PCB board 200, two diagonal tension cylinders 1502 for driving the two second suction cup assemblies 1501 to move away from or close to each other, a second suction cup lifting module 1503 for driving the two second suction cup assemblies 1501 to lift, and a second suction cup transverse movement module 1504 for driving the two second suction cup assemblies 1501 to move horizontally. The second suction cup transverse movement module 1504 is connected to the rack 1, the second suction cup lifting module 1503 is connected to the transverse movement end of the second suction cup transverse movement module 1504, the two diagonal tension cylinders 1502 are arranged on both sides of the lifting end of the second suction cup lifting module 1503, and the two second suction cup assemblies 1501 are respectively connected to the telescopic ends of the two diagonal tension cylinders 1502. The PCB board transfer mechanism 15 realizes conveying the PCB board 200 located at the board unloading station to the NG station, or conveying the co-plating boards located at the co-plating station to the board unloading station through the cooperation among the second suction cup assemblies 1501, the second suction cup lifting module 1503, and the second suction cup transverse movement module 1504. In addition, by providing two diagonal tension cylinders 1502, the PCB board transfer mechanism 15 can generate slight vibrations by controlling the telescopic movement of the diagonal tension cylinders 1502 when necessary, so as to help separate the stacked PCB boards 200 or co-plating boards and realize vibration board separation.

[0082] Please refer to Figure 1 , Figure 2In one embodiment, the tray automatic retracting and unloading machine further includes a second alignment mechanism 18 and a tray floating platform 19, both of which are installed on the tray feeding station. After the tray feeding lifting mechanism 2 receives the stack of trays 100 carrying PCB boards 200 conveyed by the loading and transporting trolley, it is first placed on the tray floating platform 19, and then the second alignment mechanism 18 aligns the position of the stack of trays 100. After alignment, the tray feeding lifting mechanism 2 then conveys the stack of trays 100 to the tray temporary storage mechanism 3 for temporary storage. The second alignment mechanism 18 and the tray floating platform 19 ensure that the tray 100 maintains the correct posture and position during the transmission process, thereby improving the stability and reliability of the overall production line.
