[0002] Automated PCB board receiving is a crucial step in PCB manufacturing. Traditional receiving equipment suffers from several shortcomings: First, the width adjustment of the feed frame relies entirely on manual operation, which is not only inefficient but also difficult to guarantee in terms of adjustment accuracy, easily leading to inaccurate positioning of the PCB within the feed frame; second, existing equipment typically employs a single-station design, limiting receiving efficiency; furthermore, insufficient coordination between the various functional modules of the equipment results in low overall operating efficiency. As the electronics manufacturing industry increasingly demands higher production efficiency and automation, this receiving method, characterized by excessive manual intervention and low automation, can no longer meet modern production needs. Especially when dealing with PCBs of different sizes, existing equipment struggles to quickly adapt to feed frame width adjustments, severely impacting the continuity and stability of the production line.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Please refer to Figures 1-10This application provides a dual-station frame-insertion type board receiving machine, the technical solution of which is as follows: A dual-station frame-insertion type board receiving machine includes a conveying mechanism 1, an edge positioning mechanism 2, a multi-axis board picking and placing mechanism 3, a frame insertion mechanism 4, a frame positioning mechanism 5, and a frame adjustment mechanism 6; the edge positioning mechanism 2 is disposed on one side of the end of the conveying mechanism 1, and is used to position the PCB board on the conveying mechanism 1 at a predetermined position; the multi-axis board picking and placing mechanism 3 is disposed at the end of the conveying mechanism 1, and is used to pick up the PCB board lifted by the edge positioning mechanism 2 one by one to the frame insertion mechanism 4; the frame positioning mechanism 5 is disposed in two receiving stations respectively, and is used to position and fix the board frame carrier 7; the frame insertion mechanism 4 is disposed above the two frame positioning mechanisms 5, and is used to insert the PCB board into the board frame carrier 7 on the frame positioning mechanism 5 in sequence; the frame adjustment mechanism 6 is disposed at the front and rear ends of the frame positioning mechanism 5, and is used to adjust the accommodating width of the board frame carrier 7 according to the width of the PCB board.

[0020] Understandably, after the PCB board is conveyed to the end by the conveyor mechanism 1, the edge positioning mechanism 2 lifts the PCB board to remove it from the conveyor surface, and then pushes it laterally to complete the position calibration. The multi-axis pick-and-place mechanism 3 picks up the positioned PCB board and transfers it above the frame insertion mechanism 4 through a preset motion trajectory. The frame insertion mechanism 4 controls the insertion angle and depth through the dual-axis module 41 to accurately insert the PCB board into the frame carrier 7 fixed by the frame positioning mechanism 5. The frame adjustment mechanism 6 drives the width adjustment side plate 71 to move to the target position and lock it according to the width parameters of the next batch of PCB boards. When the number of PCB boards in the carrier reaches the set number, the frame insertion mechanism 4 inserts the PCB board into the frame carrier 7 of another board receiving station. The two board receiving stations alternately perform the frame loading and carrier adjustment operations to achieve continuous production.

[0021] Through the above technical solutions, this application realizes the automatic adjustment of the carrier width during the PCB board mounting process, avoiding production interruption; the dual-station design allows the carrier parameter adjustment to be completed simultaneously at the other station while the equipment performs the frame insertion operation at one station, improving the overall operation efficiency; the collaborative work of each mechanism ensures the full automation of the PCB board from positioning and transfer to frame insertion, reducing the intensity of manual operation and adapting to the continuous production needs of PCB boards of different specifications.

[0022] Please refer to Figure 3This application further proposes an edge positioning mechanism 2 including an upper lifting assembly and an edge-adjusting assembly; the upper lifting assembly includes an upper lifting blade 21, a blade fixing seat 22 for mounting a plurality of upper lifting blades 21, and an upper lifting drive device 23 that is pulsatorically connected to the blade fixing seat 22; the upper lifting drive device 23 is fixedly connected to the frame, and a plurality of rollers are rotatably mounted on the top of the upper lifting blades 21 for rolling support of the PCB board; the edge-adjusting assembly includes an edge-adjusting push plate 24, a push plate fixing seat 25 for mounting the edge-adjusting push plate 24, and an edge-adjusting drive device 26 that is pulsatorically connected to the push plate fixing seat 25; the edge-adjusting drive device 26 is fixedly connected to the frame, and the output shaft of the edge-adjusting drive device 26 is connected to a synchronous belt 27, the synchronous belt 27 is located below the upper lifting blades 21, the push plate fixing seat 25 is fixedly connected to the synchronous belt 27 and extends above the upper lifting blades 21, and the displacement direction of the edge-adjusting push plate 24 is the same as the rotation direction of the rollers.

[0023] Understandably, after the PCB board is conveyed to the predetermined position, the upper drive device 23 drives the blade fixing seat 22 to rise vertically along the guide, so that the roller at the top of the upper blade 21 contacts and lifts the PCB board; at this time, the side drive device 26 drives the push plate fixing seat 25 to move laterally along the guide via the synchronous belt 27, pushing the side push plate 24 to contact the side of the PCB board, so that it moves to the precise positioning position along the rolling direction of the roller. Since the rotation direction of the roller is the same as the displacement direction of the side push plate 24, the PCB board only generates rolling friction during the lateral movement, avoiding surface scratches.

[0024] Through the above technical solutions, this application solves the technical problems of excessive manual intervention and low efficiency in the PCB board positioning process, and realizes the automated and accurate positioning of the PCB board; the roller support structure can avoid damage to the PCB board surface, and the synchronous belt 27 transmission mechanism ensures the stability and consistency of the movement of the side push plate 24.

[0025] Please refer to Figure 2 This application further proposes a conveying mechanism 1 including a roller conveyor belt 11, a baffle assembly 12, a front baffle assembly 13, and a side baffle assembly 14; the baffle assembly 12 is disposed below the roller conveyor belt 11, and the baffle assembly 12 includes a liftable interference baffle 121 and a baffle cylinder 122 for driving the interference baffle 121; the front baffle assembly 13 is disposed at the end of the roller conveyor belt 11, and the side baffle assembly 14 is disposed on one side of the roller conveyor belt 11 relative to the side assembly, for positioning the PCB board on the roller conveyor belt 11, wherein both the front baffle assembly 13 and the side baffle assembly 14 are provided with several rotatably connected sleeves.

[0026] Understandably, the roller conveyor belt 11 continuously transports the PCB board to the end area. After the PCB board reaches the predetermined position, it sends a signal to the baffle cylinder 122 to drive the interference baffle 121 to rise, blocking the subsequent PCB board from moving further. At this time, the front baffle assembly 13 and the side baffle assembly 14 respectively limit the positioned PCB board from the end and the side. The rotation characteristics of the sleeve allow the PCB board to smoothly adjust its position when it contacts the limit bar, avoiding scratches on the board surface due to rigid collision. After the previous PCB board is gripped, the baffle cylinder 122 drives the interference baffle 121 to descend, allowing the subsequent PCB board to continue to be transported.

[0027] Through the above technical solution, this application solves the problems of low positioning accuracy and easy damage to PCB boards in traditional conveying mechanisms 1, realizes dynamic detection and flexible limiting of PCB boards during the conveying process, improves the compatibility of the board receiving machine with PCB boards of various sizes, reduces the frequency of manual intervention and adjustment, and thus improves the overall board receiving efficiency and equipment stability.

[0028] Please refer to Figure 2 This application further proposes that the conveying mechanism 1 also includes an antistatic brush 15, a board measuring assembly 16, and a light source assembly 17; the antistatic brush 15 is set at the beginning of the roller conveyor belt 11 by a bracket, the board measuring assembly 16 is mounted on the bracket and is used to measure the size of the PCB board on the roller conveyor belt 11; the light source assembly 17 is set on the bracket and faces the roller conveyor belt 11.

[0029] Understandably, at the beginning of the roller conveyor belt 11, an antistatic brush 15 is fixedly installed by a bracket. Its bristles contact the surface of the PCB board, and the static electricity is discharged to the grounding device through a conductive material, thereby eliminating the charge accumulated on the PCB board during transportation. The board measurement assembly 16 is integrated on the same bracket and scans the passing PCB board using a non-contact sensor to obtain its actual size data and transmit it to the control system. The light source assembly 17 is arranged on the side or top of the bracket, projecting light onto the roller conveyor belt 11 at an inclined angle to reduce glare interference and improve image acquisition clarity.

[0030] Through the above technical solution, this application effectively solves the quality problem caused by static electricity accumulation on PCB boards, avoids errors introduced by manual measurement, and improves the lighting conditions of the testing environment, ensuring that the subsequent frame insertion mechanism 4 accurately adjusts the accommodating width of the board frame carrier 7, thereby improving the automation level and operational reliability of the dual-station board take-up machine.

[0031] Please refer to Figure 4 and Figure 10This application further proposes a multi-axis pick-and-place mechanism 3, including a six-axis robot 31 and a pick-and-place arm, the pick-and-place arm being mounted on the six-axis robot 31; the pick-and-place arm includes a width adjustment component 32, a gripper assembly 33, an adsorption component 34, and a static eliminator 35; the gripper assembly 33 is provided in two sets, one gripper assembly 33 is fixedly mounted on the width adjustment component 32, and the other gripper assembly 33 is mounted on the sliding block of the width adjustment component 32, for adjusting the distance between the two gripper assemblies 33; the gripper assembly 33 includes a fixed gripper 331 and a movable gripper 332, the fixed gripper 331 is provided with a slide cylinder, and the movable gripper 332 is fixedly mounted on the slide of the slide cylinder, for adjusting the distance between the fixed gripper 331 and the movable gripper 332; the static eliminator 35 is provided on the fixed gripper 331, for eliminating static electricity on the PCB board; the adsorption component 34 is provided on the movable gripper 332, for adsorbing and fixing the PCB board.

[0032] Understandably, the six-axis robot 31 moves the board-picking arm to the end of the conveying mechanism 1. After the edge positioning mechanism 2 lifts the PCB board, the width adjustment component 32 adjusts the distance between the two sets of gripper components 33 according to the size data fed back by the board measuring component 16. The slide cylinder drives the movable gripper 332 to move closer to the fixed gripper 331, so that the gripper component 33 adapts to the width of the PCB board. The static eliminator 35 absorbs static electricity when it comes into contact with the PCB board. After the adsorption component 34 is activated, it generates negative pressure, which, together with the clamping force of the gripper component 33, fixes the PCB board. Then, the six-axis robot 31 transfers the PCB board to the insertion frame mechanism 4, and achieves precise positioning and placement through multi-axis linkage control.

[0033] Through the above technical solution, this application realizes rapid adaptive clamping of PCB boards of different sizes, and solves the problems of low efficiency of manual adjustment and board displacement caused by electrostatic interference.

[0034] Please refer to Figures 5-6 This application further proposes a frame insertion mechanism 4 including a dual-axis module 41 and a frame insertion assembly, the frame insertion assembly being mounted on the dual-axis module 41; the dual-axis module 41 includes a Y-axis moving module and an X-axis gantry module, the Y-axis moving module being mounted on the X-axis gantry module; the frame insertion assembly includes a Z-axis moving module 42, a guide assembly 43, an upper clamping plate module 44, and a hook plate module 45; the guide assembly 43 is disposed at the bottom of the Z-axis moving module 42; the upper clamping plate module 44 is mounted on the slide of the Z-axis moving module 42 for driving the upper clamping plate module 44 to move; the hook plate module 45 is disposed on the upper clamping plate module 44; both the upper clamping plate module 44 and the hook plate module 45 are provided with inductive switches for sensing the PCB board.

[0035] Understandably, the dual-axis module 41 drives the insertion frame assembly to move along the XY plane to the predetermined work station, and the Z-axis moving module 42 drives the guide assembly 43 to descend to the height of the PCB board. The pneumatic fingers of the guide assembly 43 contact the two sides of the PCB board through rollers to form a guide channel to correct the offset. The rotary clamping cylinder 453 of the hook plate module 45 drives the hook to rotate to the bottom of the PCB board, hook the board body, and then lift it to the inlet of the board frame carrier 7 by the Z-axis module. The pneumatic gripper of the upper clamping plate module 44 simultaneously clamps the top of the PCB board. After the clamping is confirmed to be in place by the induction switch, the dual-axis module 41 inserts the PCB board into the board frame carrier 7.

[0036] Through the above technical solution, this application ensures the precise positioning of the PCB board during the insertion process by the synergistic effect of the guide component 43 and the hook plate module 45, and the configuration of the inductive switch effectively avoids board jamming failure caused by position deviation.

[0037] Please refer to Figures 5-6 This application further proposes that the guide assembly 43 includes a fixed side guide group 431 and a movable side guide group 432. The movable side guide group 432 is movably connected to the fixed side guide group 431 through a linear module and is used to adjust the distance between the movable side guide group 432 and the fixed side guide group 431. Both the fixed side guide group 431 and the movable side guide group 432 are provided with a first pneumatic finger 433 and a second pneumatic finger 434. The first pneumatic finger 433 is provided with a roller on its gripper for guiding the PCB board. The second pneumatic finger 434 is located above the first pneumatic finger 433 and is used to grip the side of the PCB board. The upper clamping plate module 44 includes a Z-axis adjustment group 441, an upper movable clamping plate group 442, and an upper fixed clamping plate group 443. The Z-axis adjustment group 441 is connected to the Z-axis moving module 42. The upper fixed clamping plate group 443 is disposed on the slide table of the Z-axis adjustment group 441. The Z-axis adjustment group 441 is used to adjust the position of the upper fixed clamping plate group 443. The upper movable clamping plate group 442 is movably connected to the upper fixed clamping plate group 443 through a linear module and is used to adjust the distance between the upper movable clamping plate group 442 and the upper fixed clamping plate group 443. The hook plate module 45 includes a movable side hook plate assembly 451 and a fixed side hook plate assembly 452, which are located on both sides of the upper clamping plate module 44. The bottom of both the movable side hook plate assembly 451 and the fixed side hook plate assembly 452 is provided with a rotary clamping cylinder 453, which is used to drive the rotary block 454 to rotate and hook the bottom of the PCB board.

[0038] Understandably, when the PCB board is transported to the insertion station, the movable side guide group 432 automatically adjusts the distance between itself and the fixed side guide group 431 according to the preset width parameters; the rollers of the first pneumatic finger 433 contact the two sides of the PCB board for guidance and positioning, and the second pneumatic finger 434 then clamps the sides of the PCB board to prevent displacement; the rotary clamping cylinder 453 of the hook plate module 45 drives the rotary block 454 to rotate 90 degrees, so that the hook plate part extends into the bottom of the PCB board to complete the hooking action; the upper clamping plate module 44 moves the upper movable clamping plate group 442 and the upper fixed clamping plate group 443 to a position suitable for the height of the current PCB board through the Z-axis adjustment group 441, and the linear module adjusts the clamping width, and cooperates with the hook plate module 45 to accurately insert the PCB board into the designated position of the board frame carrier 7.

[0039] Through the above technical solution, this application achieves automated operation of adaptive adjustment and precise positioning of PCB board width through the synergistic effect of adjustable guide component 43 and multi-level clamping mechanism, eliminating manual intervention; in particular, the combination design of rotary clamping cylinder 453 and adjustable upper clamping plate module 44 solves the problem of PCB board insertion angle deviation caused by fixed clamping structure in traditional equipment.

[0040] Please refer to Figure 8 This application further proposes a frame positioning mechanism 5 including a guide wheel assembly 51 and a receiving platform 52. Both the guide wheel assembly 51 and the receiving platform 52 are fixedly mounted on the frame. The guide wheel assembly 51 is positioned and abuts against the trolley of the plate frame carrier 7. The plate frame carrier 7 is mounted on the receiving platform 52. The receiving platform 52 is provided with a detection component 53 for detecting the alignment of the plate frame carrier 7 and a frame fixing component 54 for fixing the plate frame carrier 7.

[0041] In this embodiment, the detection component 53 includes a frame orientation detector 531, a frame type detector 532, a trolley descent detector 533, and a frame presence detector 534. The frame orientation detector 531 is disposed at the rear end of the receiving platform 52 and corresponds to the front and rear identification holes of the plate frame carrier 7. The frame type detector 532 is disposed adjacent to the frame orientation detector 531 and is used to identify the type of the plate frame carrier 7. The trolley descent detector 533 is disposed in the middle of the receiving platform 52 and is used to detect the height position of the trolley. The frame presence detector 534 is disposed in the middle of the receiving platform 52.

[0042] Through the above technical solution, this application achieves automated, precise positioning and reliable fixing of the plate-frame carrier 7, solving the technical problems of low efficiency and poor accuracy of manual adjustment. The coordinated work of the detection component 53 and the frame fixing component 54 ensures that the carrier remains stable during the frame insertion process.

[0043] Please refer to Figure 7 and Figure 9This application further proposes that the plate frame carrier 7 is provided with a slidingly disposed width-adjusting side plate 71 and a locking mechanism 72 for fixing the width-adjusting side plate 71. The frame adjustment mechanism 6 includes a front adjustment group 61 and a rear adjustment group 62, which are respectively located in the front and rear directions of the plate frame carrier 7. Both the front adjustment group 61 and the rear adjustment group 62 include a displacement component 63 and an opening clamping mechanism 64 disposed on the displacement component 63 for clamping the width-adjusting side plate 71, a sensing component 65 for identifying the position of the width-adjusting side plate 71, and a frame adjustment structure 66 for changing the locking state of the locking mechanism 72.

[0044] Understandably, when it is necessary to adjust the accommodating width of the plate frame carrier 7, the displacement component 63 drives the clamping mechanism 64 to move to the predetermined clamping position of the width-adjusting side plate 71 and clamps the edge of the side plate; the sensing component 65 monitors the alignment of the clamping mechanism 64 and the side plate in real time, and the displacement component 63 drives the clamping mechanism 64 to slide the side plate to the target position according to the feedback signal; the frame adjustment structure 66 releases the locking mechanism 72 from the side plate during the adjustment process, and after the width adjustment is completed, the locking mechanism 72 is triggered again to fix the side plate.

[0045] Through the above technical solution, this application can automatically adjust the accommodating space of the board frame carrier 7 according to the width of the PCB board, and quickly adapt the width of the board frame carrier 7 without manual intervention. The coordinated operation of the front and rear adjustment groups 62 ensures the symmetry of both sides of the board frame carrier 7.

[0046] Please refer to Figure 8 This application further proposes that the receiving platform 52 is arranged symmetrically on the left and right sides. The receiving platform 52 includes a mounting bracket 521, a floating plate 522, a centering component 523, a jig lock 524, and a plate frame blocking component 525. The floating plate 522 and the centering component 523 are located on the top of the mounting bracket 521 to support and position the plate frame carrier 7. The jig lock 524 is located at the front end of the mounting bracket 521, and the plate frame blocking component 525 is located at the rear end of the mounting bracket 521 to fix the plate frame carrier 7.

[0047] Understandably, when the trolley transports the plate frame carrier 7 to the receiving platform 52, the trolley limiting component restricts the trolley's position through mechanical guidance or photoelectric detection, maintaining a preset distance between it and the mounting bracket 521. After the plate frame carrier 7 is transferred to the floating plate 522, the centering component 523 is activated, and the positioning blocks on both sides move synchronously towards the center, pushing the plate frame carrier 7 to the predetermined center position. After centering is completed, the fixture latch 524 automatically closes and locks the front end of the plate frame carrier 7, and the plate frame blocking component 525 rises or extends the limiting pin to fix its rear end, forming a three-point positioning constraint. During this process, the buffering function of the floating plate 522 avoids positioning deviations caused by rigid contact, and the bidirectional synchronous drive of the centering component 523 ensures that the plate frame carrier 7 is symmetrically centered.

[0048] Through the above technical solution, this application solves the technical problems of low positioning efficiency and easy deviation of plate and frame carrier 7 during the receiving process, realizes rapid automatic centering and reliable fixation of the carrier, reduces the impact of equipment operation, and adapts to the high-precision positioning requirements of plate and frame carrier 7 of different sizes.
