Description

Technical Field

[0001] The invention relates to the technical field of printed circuit board manufacturing, and in particular to a double-station temporary storage device and method between PCB processes. Background Art

[0002] In the manufacturing process of PCB work boards, it usually takes dozens of processes and hundreds of steps to complete the processing. Since the processing time of each process or step is different, in order to achieve automated production and avoid traffic jams or overcapacity, it is usually necessary to set up a temporary storage machine between specific processes or steps for buffering.

[0003] At present, the number of work boards temporarily stored within a process or between work steps is usually not large, and is usually controlled within 50Pnl according to the processing unit. Different from the temporary storage within a process or between work steps, the number of work boards temporarily stored between processes is usually larger, and most of them use more than 2LOT cards as transfer units. However, 1LOT card usually has hundreds of Pnl work boards in a highly automated processing factory. Therefore, it is impossible to use temporary storage machines within the process or between work steps for buffering. It basically relies on human-machine cooperation to place the PCB work boards in designated storage locations for temporary storage, which lacks flexibility and adaptability, easily leading to bottlenecks and stagnation in the production process, and thus lowering production efficiency, restricting the development of PCB towards higher automation.

[0034] refer to Figures 1 to 4 A double-station temporary storage device and method between PCB processes according to an embodiment of the present invention are described.

[0035] like Figure 1 and Figure 3 As shown, the double-station temporary storage device between PCB processes according to the first aspect of the present invention includes: a frame 100; a horizontal line mechanism 200, the horizontal line mechanism 200 is arranged on the frame 100, the input end of the horizontal line mechanism 200 is connected to the output end of the first process, and the output end of the horizontal line mechanism 200 is connected to the input end of the second process; two temporary storage mechanisms 300, the two temporary storage mechanisms 300 are slidably arranged on the frame 100, the two temporary storage mechanisms 300 are respectively located on opposite sides of the horizontal line mechanism 200, and each temporary storage mechanism 300 can reciprocate in the direction of approaching and moving away from the input end of the second process; two sliding mechanisms 400, the two sliding mechanisms 400 are both arranged on the frame 100, each temporary storage mechanism 300 is correspondingly provided with a sliding mechanism 400, and the sliding mechanism 400 is located on the horizontal line mechanism 20 0, the sliding mechanism 400 is used to drive the temporary storage mechanism 300 to reciprocate between the first board collecting station 10 and the first board placing station 20 and between the second board collecting station 30 and the second board placing station; the board collecting mechanism 500, the board collecting mechanism 500 is arranged on the frame 100, the first board collecting station 10 and the second board collecting station 30 both correspond to the board collecting mechanism 500, the board collecting mechanism 500 is used to transfer the PCB working board on the horizontal line mechanism 200 to the temporary storage mechanism 300 on the first board collecting station 10 or the second board collecting station 30; the board placing mechanism 600, the board placing mechanism 600 is arranged on the frame 100, the first board placing station 20 and the second board placing station both correspond to the board placing mechanism 600, the board placing mechanism 600 is used to transfer the PCB working board on the first board placing station 20 or the second board placing station to the horizontal line mechanism 200.

[0036] like Figures 1 to 3As shown, the horizontal line mechanism 200 extends in the front-to-back direction, the front end of the horizontal line mechanism 200 is the input end, and the rear end is the output end, the input end is connected to the first process, and the output end is connected to the second process. A temporary storage mechanism 300 is respectively arranged on the left and right sides of the horizontal line mechanism 200, each temporary storage mechanism 300 is correspondingly arranged with a sliding mechanism 400, each temporary storage mechanism 300 is movably connected to the frame 100 through the sliding mechanism 400, the sliding mechanism 400 extends in the front-to-back direction, and the temporary storage mechanism 300 reciprocates in the front-to-back direction under the action of the sliding mechanism 400. The plate placing mechanism 600 and the plate collecting mechanism 500 are both arranged on the frame 100.

[0037] The PCB boards that have completed the first process are output to the horizontal line mechanism 200 in sequence, and the board collecting mechanism 500 collects the PCB working boards to one of the temporary storage mechanisms 300 for stacking. After the number of PCB boards stored in one of the temporary storage mechanisms 300 reaches a preset number of PCB boards, it moves toward the direction close to the input end of the second process. At the same time, the board collecting mechanism 500 collects the PCB working boards to another temporary storage mechanism 300 for stacking. When the parameter adjustment of the second process is completed, the board placing mechanism 600 transfers the PCB working boards stored in the temporary storage mechanism 300 close to the side of the second process to the horizontal line mechanism 200 in sequence, and the horizontal line mechanism 200 outputs the PCB working boards to the second process in sequence. After all the PCB working boards have completed the movement, the temporary storage mechanism 300 is moved in the direction close to the input end of the first process. Similarly, after the number of PCB boards stored in the temporary storage mechanism 300 of the second board collecting station 30 reaches a preset number of PCB boards, it moves toward the direction close to the input end of the second process. At the same time, the board collecting mechanism 500 collects the PCB working boards to the temporary storage mechanism 300 close to the side of the first process for stacking, and this cycle is repeated.

[0038] Therefore, through the automated PCB work board transfer and stacking process, various errors that may occur when the human-machine cooperation in transferring PCB work boards between processes is reduced, and the problem of difficulty in automated connection due to different horizontal line speeds and too many temporarily stored PCB work boards between the upper and lower processes is effectively solved, making the connection between the processes smoother, thereby improving the intelligence and automation level of the production line, and improving production efficiency and product quality.

[0039] In this specific embodiment, the plate placing mechanism 600 and the plate collecting mechanism 500 are both located above the horizontal line mechanism 200, and the plate collecting mechanism 500 and the plate placing mechanism 600 are arranged in sequence from front to back. Specifically, the plate placing mechanism 600 and the plate collecting mechanism 500 are both six-axis robotic arms, and the manipulator of the six-axis robotic arm is a suction cup structure, which is composed of a plurality of suction cups arranged and combined, and the spacing between the plurality of suction cups and the negative pressure of each suction cup can be adjusted. The appropriate suction cup spacing and negative pressure are adjusted according to different specifications of PCB working boards to ensure that the PCB working board will not fall off during the operation of the robotic arm.

[0040] According to some specific embodiments of the present invention, the two temporary storage mechanisms 300 are respectively arranged on opposite sides perpendicular to the extension direction of the horizontal line mechanism 200, and the two temporary storage mechanisms 300 both move along the extension direction of the horizontal line mechanism 200. Figure 1 As shown, the two temporary storage mechanisms 300 are respectively located on the left and right sides of the horizontal line mechanism 200 , and the two temporary storage mechanisms 300 can reciprocate along the front-rear direction through the corresponding sliding mechanisms 400 .

[0041] According to some specific embodiments of the present invention, the first board collecting station 10 is located on a side of the first board placing station 20 close to the output end of the first process, the second board collecting station 30 is located on a side of the second board placing station close to the output end of the first process, the first board collecting station 10 and the second board collecting station 30 are respectively located on opposite sides of the horizontal line mechanism 200, and the first board placing station 20 and the second board placing station are respectively located on opposite sides of the horizontal line mechanism 200.

[0042] like Figure 1 As shown, the first board collecting station 10 and the second board collecting station 30 are respectively located on the left and right sides of the horizontal line mechanism 200, and the first board placing station 20 and the second board placing station are respectively located on the left and right sides of the horizontal line mechanism 200, wherein the first board collecting station 10 and the first board placing station 20 are located on the left side of the horizontal line mechanism 200 and are arranged sequentially from front to back, and the second board collecting station 30 and the second board placing station are located on the right side of the horizontal line mechanism 200 and are arranged sequentially from front to back. When the double-station temporary storage device between the PCB process is not working, the temporary storage mechanisms 300 on the left and right sides of the horizontal line mechanism 200 are respectively located on the first board receiving station 10 and the second board receiving station 30. When the number of PCB boards stored in the temporary storage mechanism 300 of the first board receiving station 10 reaches the preset number of PCB boards, the temporary storage mechanism 300 on the left side moves backward from the first board receiving station 10 to the first board placing station 20, and at the same time, the board receiving mechanism 500 collects the PCB working board into the temporary storage mechanism 300 of the second board receiving station 30 for stacking. Stacking, and when all PCB work boards on the left temporary storage mechanism 300 have completed the movement, the left temporary storage mechanism 300 is moved forward from the first board placing station 20 and returned to the first board collecting station 10. Similarly, when the PCB boards stored in the temporary storage mechanism 300 of the second board collecting station 30 reaches the preset number of PCB boards, the temporary storage mechanism 300 on the right side moves backward from the second board collecting station 30 to the second board placing station. At this time, the board collecting mechanism 500 collects the PCB work boards onto the left temporary storage mechanism 300 for stacking.

[0043] It can be seen that by moving the temporary storage mechanism 300 back and forth between the first board collecting station 10 and the first board placing station 20, and between the second board collecting station 30 and the second board placing station, the role conversion of board collecting and board placing is realized, thereby realizing the storage of multiple batches of PCB work boards and realizing the automatic connection between the upper and lower processes.

[0044] According to some specific embodiments of the present invention, a first scanning mechanism is further included. The first scanning mechanism is arranged at the input end of the horizontal line mechanism 200. The first scanning mechanism is used to ensure that the correct PCB working board is introduced into the horizontal line mechanism 200 to monitor and track the flow direction and status of the PCB working board.

[0045] According to some specific embodiments of the present invention, a second scanning mechanism is further included. The second scanning mechanism is arranged at the output end of the horizontal line mechanism 200. The second scanning mechanism is used to record the data of the PCB boards shipped out of the warehouse to monitor and track the flow direction and status of the PCB working boards.

[0046] like Figure 1 and Figure 3 As shown, the first scanning mechanism is arranged at the front end of the horizontal line mechanism 200, and the second scanning mechanism is arranged at the rear end of the horizontal line mechanism 200. It should be noted that a corresponding QR code is arranged on the edge of each PCB work board, and the QR code carries the basic information of the PCB work board, including model, quantity, processing information, etc. After the PCB work boards output from the first process are transported to the horizontal line mechanism 200 one by one, the first scanning mechanism is used to scan the QR codes on the PCB work boards in turn and obtain the corresponding product information, and the corresponding product information is entered and uploaded to the MES system to ensure that the PCB work boards are introduced into the temporary storage area, which is convenient for subsequent tracking, management and processing. When the board placement mechanism 600 transfers the PCB work boards stored by the temporary storage mechanism 300 on the first board placement station 20 or the second board placement station to the horizontal line mechanism 200 one by one, the second scanning mechanism scans the QR code on the PCB work board in turn and obtains the corresponding product information, enters the corresponding product information and uploads it to the MES system to collect the information of the PCB work board leaving the horizontal line mechanism 200 and record the material data out of the warehouse. Therefore, the first scanning mechanism and the second scanning mechanism are combined with the automated control system to trigger corresponding operations and processes according to the scanning results, thereby avoiding problems caused by human errors or negligence. At the same time, the data collected by the first scanning mechanism and the second scanning mechanism can record the flow trajectory and status of the PCB board, thereby realizing the traceability of the PCB board.

[0047] According to some specific embodiments of the present invention, the temporary storage mechanism 300 includes a base 310 and a limiter 320. The base 310 is slidably disposed on the frame 100. The limiter 320 is disposed on the base 310. The limiter 320 is used to limit the position of the PCB working board.

[0048] like Figure 2 and Figure 3As shown, the base 310 is slidably set on the frame 100. Specifically, the sliding mechanism 400 includes a guide rail 410 set along the front and rear directions, a slider 420 slidably set on the guide rail 410, and a driving member for driving the slider 420. The slider 420 is fixedly connected to the base 310. The base 310 can reciprocate along the direction limited by the guide rail 410 through the slider 420. The limiter 320 is set at the upper end of the base 310. The board collecting mechanism 500 collects the PCB working boards output to the horizontal line mechanism 200 in sequence onto the limiter 320 of the first board collecting station 10 for stacking, so as to ensure that the PCB working boards are stacked in a fixed position and height, thereby maintaining the neatness and stability of the PCB working boards, which helps to avoid misalignment or tilting when the PCBs are stacked.

[0049] In this specific embodiment, the limiting member 320 is an L-frame, and one end of the limiting member 320 away from the horizontal line mechanism 200 has a vertically arranged baffle, and baffles are arranged in the front and rear directions.

[0050] According to some specific embodiments of the present invention, a plurality of limit members 320 are provided, and the plurality of limit members 320 can be individually and alternately installed on the base 310, and the plurality of limit members 320 are individually and alternately installed on the base 310 to change the stacking quantity of the PCB working boards.

[0051] It should be noted that the limit member 320 can enable the PCB working boards to be continuously stacked within the allowed range to achieve stacking of multiple LOTs, and the first scanning mechanism and the second scanning mechanism can ensure that there will be no model and quantity errors in the PCB working boards during the stacking process. The number of stacks depends on the size of the limit member 320. Therefore, multiple limit members 320 are designed according to the production specifications of the PCB working board production line, and the limit members 320 of appropriate sizes are replaced according to different production needs, so as to adapt to different production needs and process requirements and improve the flexibility and production efficiency of the production line.

[0052] like Figure 4 As shown, the PCB process duplex temporary storage method according to the second aspect of the present invention includes:

[0053] S1: confirming the first process of the PCB board, and outputting the PCB boards that have completed the first process to the horizontal line mechanism 200 in sequence;

[0054] S2: using the board collecting mechanism 500 to collect the PCB working board to the temporary storage mechanism 300 of the first board collecting station 10 for stacking, until the number of PCB boards stored in the temporary storage mechanism 300 of the first board collecting station 10 reaches a preset number of PCB boards;

[0055] S3: Move the temporary storage mechanism 300 from the first board receiving station 10 to the first board placing station 20, and use the board receiving mechanism 500 to receive the PCB working board to the temporary storage mechanism 300 of the second board receiving station 30 for stacking;

[0056] S4: confirming the second process of the PCB work board. When the parameter adjustment of the second process is completed, the PCB work board stored by the temporary storage mechanism 300 on the first board placement station 20 is sequentially transferred to the horizontal line mechanism 200 by the board placement mechanism 600. The horizontal line mechanism 200 outputs the PCB work board to the second process in sequence.

[0057] S5: Returning the temporary storage mechanism 300 from the first board placing station 20 to the first board receiving station 10 .

[0058] In S1, after the PCB work boards output from the first process are transported to the horizontal line mechanism 200 one by one, the first scanning mechanism is used to scan the QR codes on the PCB work boards in turn and obtain corresponding product information, and the corresponding product information is entered and uploaded to the MES system.

[0059] In S4, after the board placement mechanism 600 transfers the PCB work boards stored by the temporary storage mechanism 300 on the first board placement station 20 to the horizontal line mechanism 200 one by one, the second scanning mechanism is used to scan the QR code on the PCB work board in turn and obtain the corresponding product information, and the corresponding product information is entered and uploaded to the MES system.

[0060] In S5 , the number of PCB working boards is confirmed, and the temporary storage mechanism 300 is returned from the first board placing station 20 to the first board receiving station 10 after all PCB working boards have completed their movement.

[0061] The following is a specific embodiment to illustrate the double-station temporary storage method between PCB processes.

[0062] Confirm the first process of the PCB board, and output the PCB boards that have completed the first process to the horizontal line mechanism 200 in sequence. Use the first scanning mechanism to scan the QR code on the PCB work board in sequence and obtain the corresponding product information, and enter the corresponding product information and upload it to the MES system.

[0063] The board receiving mechanism 500 is used to receive the PCB working boards to the temporary storage mechanism 300 of the first board receiving station 10 for stacking. The PCB working boards are scanned and received in sequence, and the order of the PCB boards stacked in sequence is recorded.

[0064] When the number of PCB boards stored in the temporary storage mechanism 300 of the first board collecting station 10 reaches a preset number of PCB boards, the temporary storage mechanism 300 is moved backward from the first board collecting station 10 to the first board placing station 20. At this time, the board collecting mechanism 500 turns to the second board collecting station 30, and the subsequently input PCB work boards are collected and stacked on the temporary storage mechanism 300 of the second board collecting station 30.

[0065] Confirm the second process of the PCB work board. When the parameter adjustment of the second process is completed, the board placement mechanism 600 is used to transfer the PCB work board stored by the temporary storage mechanism 300 on the first board placement station 20 to the horizontal line mechanism 200 in sequence. The horizontal line mechanism 200 outputs the PCB work board to the second process in sequence. At the same time, the second scanning mechanism is used to scan the QR code on the PCB work board output to the second process in sequence and obtain the corresponding product information. The corresponding product information is entered and uploaded to the MES system to identify and record the data of the PCB work board out of the warehouse, thereby effectively preventing mistakes and avoiding human errors. While improving the accuracy and reliability of the production line, the automatic tracking, management and control of the PCB work board are realized.

[0066] Confirm the number of PCB work boards, and return the temporary storage mechanism 300 from the first board placement station 20 to the first board collection station 10 after all PCB work boards have finished moving. It should be noted that if the temporary storage mechanism 300 on the second board collection station 30 has not yet finished the board collection action, the temporary storage mechanism 300 on the first board collection station 10 is in a standby state. When the number of PCB boards stored in the temporary storage mechanism 300 on the second board collection station 30 reaches the preset number of PCB boards, the temporary storage mechanism 300 is moved backward from the second board collection station 30 to the second board placement station. At this time, the board collection mechanism 500 turns to the first board collection station 10, and collects the subsequently input PCB work boards to the temporary storage mechanism 300 of the first board collection station 10 for stacking, thereby realizing the role conversion of the board collection function and the board placement function of the same temporary storage mechanism 300, effectively solving the problem of difficulty in automatic connection between the upper and lower processes due to different horizontal line speeds and too many temporary PCB work boards, making the connection between the various processes smoother.

[0067] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
