Description

Technical Field

[0001] This invention relates to the field of PCB board labeling technology, and in particular to a double-sided labeling machine. Background Technology

[0002] In the electronics manufacturing industry, printed circuit boards (PCBs) serve as carriers for electronic components. Their surfaces typically require labels containing product information, traceability codes, and other information to facilitate subsequent production management and quality traceability. As PCB products develop towards higher density and miniaturization, higher demands are placed on the accuracy, efficiency, and intelligence of labeling equipment.

[0003] Currently, existing PCB labeling equipment on the market typically uses a flipping mechanism to rotate the board to achieve double-sided labeling. During this rotation, the board is fixed using direct clamping or suction, lacking real-time feedback on the clamping status. When the PCB board shifts position or the clamping becomes unstable, it's difficult to detect in time, leading to a higher defect rate. Furthermore, the board rotation process can easily introduce positional deviations, affecting labeling accuracy. Simultaneously, the nozzles in existing labeling components are mostly arranged with fixed spacing along the same horizontal line, making it difficult to adapt to multi-point labeling needs at different horizontal positions on the same PCB board. This usually requires frequent movement of the entire labeling module, resulting in large strokes and low efficiency. Moreover, the nozzles cannot flexibly adjust the label angle after picking up the label, making it unsuitable for labeling requirements with non-standard angles. Therefore, we propose a double-sided labeling machine. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves online automatic flipping and double-sided labeling of PCB boards by driving the mounting frame to rotate as a whole through the second drive module in the feeding assembly, and cooperating with the first drive module in the support assembly to drive the support plate and support column to swing downwards by 90 degrees for active avoidance. At the same time, the conveyor lines one and two symmetrically arranged on both sides of the mounting frame can realize the continuous feeding and discharging of PCB boards. The cyclic rotation of the conveyor belt and the clamping and positioning of the PCB boards by the gripper blocks make the flow of PCB boards in the labeling process smooth and orderly, improving the degree of automation.

[0014] 2. This invention, by setting pressure sensors on the gripper blocks, detects the clamping pressure value in real time when the PCB board is clamped and feeds it back to the external controller. Based on the pressure signals fed back by the gripper blocks at different positions, the current workstation position of the PCB board can be accurately determined. This ensures that the PCB board is reliably fixed, avoids deviations caused by loosening during the labeling process, and can also detect and correct positional errors in a timely manner, reducing the defect rate caused by inaccurate positioning.

[0015] 3. This invention, by setting a horizontal position adjustment mechanism consisting of roller groups, toothed belts, slides, and power supply rods in the control box of the labeling assembly, and cooperating with the engagement and disengagement of the electric cylinder three-push block with the inner wall of the corresponding roller group slot, can selectively drive different roller groups to rotate. This, in turn, drives the slide to constrain the air core rod to slide horizontally along the slide groove through the toothed belt, realizing the staggered adjustment of the horizontal position between each group of air nozzles. It can adapt to multiple labeling positions on the PCB board that are not on the same horizontal line, without the need to frequently move the entire assembly frame, reducing the stroke and improving labeling efficiency.

[0016] 4. This invention achieves the up-and-down movement of the air nozzle by setting a constraint block and an electric cylinder on the side of the air core rod. At the same time, by spline-connecting a gear to the air core rod, and cooperating with the constraint frame for limiting and the motor driving the gear to mesh with the gear, the air core rod can move up and down while driving the air nozzle to rotate around its own axis. This allows for flexible adjustment of the label application angle, adapting to different labeling angle requirements and improving the versatility and labeling flexibility of the equipment.

[0019] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example: Figures 1 to 3As shown, the double-sided labeling machine includes a cabinet 1, which integrates control and power supply modules. A label supply module 2 is fixedly installed on the upper side of the cabinet 1. The label supply module 2 consists of multiple label conveying devices that supply multiple or different types of labels. A support component 3 is installed at the center of the upper side of the cabinet 1. The support component 3 can support the PCB board. A feeding component 4 is installed on the side of the support component 3. The feeding component 4 can convey and flip the PCB board and perform positioning detection. A labeling component 5 is installed on the upper side of the support component 3 and the feeding component 4. The labeling component 5 works with the label supply module 2 to quickly label the label after picking it up.

[0021] like Figures 3 to 6 As shown, the support assembly 3 includes a unidirectional transfer module 31, which is symmetrically fixed at the upper center of the cabinet 1. The unidirectional transfer module 31 consists of a motor, a synchronization component, and a threaded rod. A movable frame 32 is mirror-imagely arranged on the side of the unidirectional transfer module 31, and the movable frame 32 is threaded onto the side of the threaded rod of the unidirectional transfer module 31. The movable frame 32 is a rectangular frame. A drive module 33 is mirror-imagely fixed on the side of the movable frame 32 that is far away from it. The drive module 33 consists of a motor and a synchronization component. A synchronization rod 331 is fixedly connected to the output end of the drive module 33, and the synchronization rod 331 is rotatably mounted on the movable frame 33 via a bearing. On the side of the moving frame 32, the synchronizing rod 331 is a regular hexagonal rod. Support plates 332 are fixedly sleeved at equal intervals on the side of the synchronizing rod 331. The support plates 332 are adjustable "L"-shaped rods. Support columns 333 are fixedly installed on the side of the support plates 332. The upper end of the support columns 333 is made of rubber. Specifically, when the PCB board is labeled, the drive module 33 drives the synchronizing rod 331 to rotate. The synchronizing rod 331 can then synchronously drive the support plates 332 and the support columns 333 to swing to the lower side of the PCB board for support. When the PCB board is flipped, the drive module 33 drives the synchronizing rod 331 to make the support plates 332 and the support columns 333 swing downward by ninety degrees to avoid the PCB board.

[0022] like Figures 3 to 10As shown, the feeding assembly 4 includes a second drive module 41, which is fixedly mounted at the center of the side of the movable frame 32. The second drive module 41 consists of a motor and a turntable. The turntable passes through the movable frame 32 and is located on the other side of the motor. A mounting frame 42 is fixedly mounted on the side of the turntable of the second drive module 41. The mounting frame 42 is a rectangular frame. Movable plates 421 are symmetrically arranged at equal intervals on the side of the mounting frame 42. The movable plates 421 at corresponding positions are slidably mounted on the side of the mounting frame 42 via a slide rail module. An elastic element 422 is fixedly installed on the side of the movable plate 421, with the other end of the elastic element 422 attached to the inner side of the mounting bracket 42. The elastic element 422 elastically supports the corresponding movable plate 421 to be attached together. Gripper blocks 423 are fixedly installed at equal intervals on the side of the movable plate 421. The gripper blocks 423 are "L"-shaped blocks. A pressure sensor 425 is fixedly installed through the side of the gripper blocks 423 that are close to each other. A battery module 424 is fixedly installed inside the gripper blocks 423, and the battery module 424 is connected to the pressure sensor. The sensor 425 is connected to the circuit, and the battery module 424 can be connected to the power supply module via an external wire. A trigger block 45, which is a protrusion, is fixedly installed on the side of the movable plate 421 away from the gripper block 423. Electric cylinder 451 is symmetrically fixedly installed on the side of the movable frame 32. A trigger wheel 452, which is a circular roller, is fixedly installed at the output end of electric cylinder 451 and corresponds to the position of trigger block 45. Specifically, the turntable of drive module 2 41 can drive the entire mounting frame 42 to rotate and flip. During rotation, the movable plate 421 is elastically supported by the elastic element 422 by default, so that the corresponding side gripper block 423 contacts and clamps the PCB board. During clamping, the pressure sensor 425 detects the pressure value and feeds it back to the external controller. The electric cylinder 451 pushes the trigger wheel 452, and the trigger wheel 452 squeezes the trigger block 45, so that the trigger block 45 on the side of the movable plate 421 moves away from each other. At the same time, the movable plate 421 moves away from each other, and the gripper block 423 releases the PCB board by disengaging from the contact state. Conveyor line 1 43 and conveyor line 2 44 are respectively provided on both sides of the mounting frame 42. Conveyor line 1 43 and conveyor line 2 44 are fixedly located on the upper side of the cabinet 1. Conveyor line 1 43 and conveyor line 2 44 are composed of a motor, conveyor belt and support shaft, and can transport PCB boards. Support rods 46 are symmetrically and rotatably installed through the side of the mounting frame 42. Two sets of conveyor belts 461 are symmetrically arranged on the side of the mounting frame 42, and the conveyor belts 461 are movably sleeved on the side of the corresponding support rods 46. Drive wheels 462 are fixedly installed on the side of the support rods 46 near the movable frame 32 at the staggered position. Drive module 3 47 is fixedly installed through the side of the movable frame 32. Drive module 47 is attached to the side of the corresponding support rod 46 and drive wheel 462. Drive module 47 consists of a motor and rollers. Specifically, the PCB board is conveyed to the mounting bracket 42 via conveyor line 43. At this time, drive module 47 rotates, causing the corresponding drive wheel 462 to rotate synchronously in the opposite direction. The support rod 46 attached to drive module 47 also rotates accordingly. The two sets of conveyor belts 461 can then rotate in opposite directions to move the PCB board. At this time, the electric cylinder 451 near the side of conveyor line 43 pulls the trigger wheel 452 away from the side of trigger block 45. The corresponding movable plate 421 is elastically supported by elastic element 422, causing the gripper block 423 to clamp the side of the PCB board. Pressure sensor 425 detects the clamping pressure value and feeds it back to the external controller to confirm that the PCB board is fixed. Then, the labeling assembly 5 labels the PCB board. Next, the electric cylinder 451 near the conveyor line 43 pushes the trigger wheel 452 to press against the side of the trigger block 45, and the gripper blocks 423 move away to release the PCB board. The conveyor belt 461 continues to transport the PCB board to the center position of the mounting bracket 42. At this time, the electric cylinders 451 on both sides pull the trigger wheel 452 away from the side of the trigger block 45, and the corresponding gripper blocks 423 clamp the PCB board. The pressure value fed back by the pressure sensor 425 can determine which gripper blocks 423 are clamping the PCB board, thus determining the PCB board's position. If the PCB board is in the correct position, drive module 2 41 drives the mounting bracket 42 to rotate 180 degrees and flip it over. Simultaneously, the other support rod 46 and drive wheel 462 are attached to the side of the roller of drive module 3 47. The two sets of trigger wheels 452 press against the side of the trigger block 45 to release the PCB board. The conveyor belt 461 continues to rotate and transport the PCB board to the side position of conveyor line 2 44. Similarly, the gripper block 423 at the side position of conveyor line 2 44 clamps and fixes the PCB board. The labeling component 5 is labeled on the other side. At the same time, the next set of PCB boards can be transported to the mounting bracket 42 position through conveyor line 1 43. After double-sided labeling is completed, the PCB board is transported out through conveyor line 2 44.

[0023] like Figures 11 to 20As shown, the labeling component 5 includes a bidirectional transfer module 51, which is fixedly installed on the upper side of the cabinet 1. The bidirectional transfer module 51 consists of two sets of electric slides arranged vertically. Two sets of mating frames 52 are slidably installed on the side of the bidirectional transfer module 51. The mating frame 52 is a U-shaped frame composed of multiple rectangular plates. A vision module 53 is fixedly installed on the side of the mating frame 52. A control box 54 is fixedly installed at equal intervals on the inner side of the mating frame 52. The control box 54 is a hollow rectangular box. A through groove 541 is opened on the lower side of the control box 54. The groove 541 is a rectangular groove. A connection port 55 is fixedly installed on the side of the mating frame 52 corresponding to the position of the control box 54. An external compressed air pipe is connected through the connection port 55. An air core rod 552 is installed inside the control box 54 and passes through the groove. Extending from inside 541, the air core rod 552 is a cylindrical tube with spline grooves on some sides. An air nozzle 553 is fixedly installed on the lower side of the air core rod 552. A slide rail frame 551 is fixedly installed on the upper wall inside the control box 54. An air pipe 554 is fixedly connected between the connection port 55 and the air core rod 552, and the air pipe 554 is constrained to slide by the slide rail frame 551. Specifically, when the air core rod 552 slides inside the slide groove 541, the air core rod 552 drives the air nozzle 553 to move synchronously. Gas can be introduced through the connection port 554 and the air pipe 554. The air nozzle 553 can be switched by the external control air valve to attract and release the label. When the air core rod 552 moves, the slide rail frame 551 can slide and guide the air pipe 554 to prevent the air pipe 554 from being unrestrained and tangled. An inner frame 56 is slidably mounted on the inner side of the control box 54. The inner frame 56 is a combination of rectangular plates and cylinders. A constraint block 561, which is a circular ring frame, is fitted onto the side of the air core rod 552. An electric cylinder 562 is symmetrically fixedly mounted on the inner side of the inner frame 56, and its output end is fixedly connected to the upper side of the constraint block 561. A gear 563, which is a splined ring gear, is fitted onto the side of the air core rod 552 and is positioned above the electric cylinder 562. Gear 563 is a circular ring gear with an inner splined shape. A gear 564, which is a circular gear, meshes with the side of gear 563. A motor 565 is fixedly mounted on the inner side of the inner frame 56, corresponding to the position of gear 564, and its output end is fixedly connected to the side of gear 564. A constraint frame 566 is provided on the side of 3 away from the limit of gear 2 564 and is fixedly installed on the inner side of the inner frame 56. The constraint frame 566 is a "C" shaped block and limits gear 1 563. Specifically, electric cylinder 2 562 pushes and pulls constraint block 561 to move. Simultaneously, constraint block 561 can constrain and drive air core rod 552 to move up and down, so that the label attracted by air nozzle 553 can be attached to the side of PCB board. At the same time, when the frame 52 and label supply module 2 move, air core rod 552 always maintains spline engagement inside gear 1 563. Motor 1 565 drives gear 2 564 to mesh with gear 1 563. With the constraint frame 566 constraining gear 1 563, air core rod 552 can rotate, so that the label attracted by air nozzle 553 can change the angle for attachment. Two sets of roller assemblies 57 are symmetrically arranged on the inner side of the control box 54. Each roller assembly 57 is a circular block with circular gears fixedly mounted on both sides. A slot 571 is opened through the side of each roller assembly 57, and the slot 571 is a cylindrical cavity with a cross-shaped cross section. A damping rod 572 is fixedly mounted on the inner side of one set of slots 571, and the two ends of the damping rod 572 pass through the control box 54 and are rotatably mounted therewith. The damping rod 572 is an I-shaped cylindrical rod made of wear-resistant rubber. Toothed belts 573 are symmetrically meshed and sleeved at the gears of the two sets of roller assemblies 57. A slide 574 is fixedly installed between the sides of the toothed belt 573, and the slide 574 is movably sleeved on the side of the air core rod 552. A power supply rod 58 is movably arranged inside another set of roller groups 57. The power supply rod 58 extends through to the inside of all corresponding roller groups 57. The power supply rod 58 is a cylindrical rod-shaped rechargeable module. Electric cylinders 581 are fixedly and equidistantly mirrored on the side of the power supply rod 58 and are electrically connected to the power supply rod 58. The electric cylinders 581 are located inside the slot 571. The output end of the 1 is fixedly equipped with a locking block 582, which is engaged and abutted against the wall of the slot 571. A second motor 59 is fixedly connected to one end of the power supply rod 58, and the second motor 59 is fixedly installed on the side of the corresponding control box 54. Specifically, the second motor 59 drives the power supply rod 58 to rotate, and the electric cylinder 581 on the side of the power supply rod 58 can simultaneously rotate inside the slot 571. When the corresponding roller group 57 needs to be driven, the electric cylinder 581 pushes the locking block 582 to engage and abut against the slot 571 of the corresponding roller group 57. At this time, the corresponding roller group 57 rotates with the power supply rod 58, and another roller group 57 is constrained by the damping rod 572 to rotate. The toothed belt 573 can then rotate cyclically under the support of the roller group 57. The slide 574 then constrains the air core rod 552 to slide in the slide groove 541. This allows for staggered adjustment of the horizontal position between each set of air nozzles 553 to adapt to multiple labeling positions on the PCB board that are not on the same horizontal line. There is no need to frequently move the entire set of mounting brackets, thereby improving the overall labeling efficiency.

[0024] Working principle: In use: First, the first side of the PCB board is labeled. The first group of PCB boards is conveyed to the mounting frame 42 via the corresponding conveyor line 43. At this time, the drive module 47 on the side of the conveyor line 43 drives the corresponding support rod 46 and drive wheel 462 to rotate. The two sets of conveyor belts 461 can rotate in opposite directions to constrain the PCB board to move to the side of the mounting frame 42 near the side of the conveyor line 43. The electric cylinder 451 on the side of the conveyor line 43 pulls the trigger wheel 452 to disengage from the side of the trigger block 45. The corresponding movable plate 421 is subjected to the elastic element 42. 2. The elastic support clamps the gripper block 423 to the side of the PCB board and fix it. The drive module 33 on the side of the synchronous conveyor line 43 drives the synchronous rod 331 to rotate, so that the corresponding support plate 332 and support column 333 support and fit against the lower side of the PCB board. Then, the bidirectional transfer module 51 drives the corresponding mating frame 52 to move as a whole. The air nozzle 553 picks up the label from the label supply module 2. After the bidirectional transfer module 51 moves the mating frame 52 so that the air nozzle 553 corresponds to the position of the PCB board, the air nozzle 553 performs the labeling operation. The second step is to flip the PCB board. After the first side is labeled, the trigger wheel 452 on the side of the conveyor line 43 presses the corresponding trigger block 45, causing the gripper block 423 to move away from each other and release the first set of PCB boards. Then the conveyor belt 461 transports the PCB board to the center position of the mounting frame 42. The trigger wheels 452 on both sides of the mounting frame 42 disengage from the side of the trigger block 45. The corresponding movable plate 421 is reset by the elastic force of the elastic element 422. The gripper block 423 can then clamp the side of the PCB board. The drive module 2 41 drives the mounting frame 42 to rotate 180 degrees. At the same time, all drive modules 1 33 drive the corresponding support plate 332 and support column 333 to rotate to a downward vertical 90-degree angle to avoid the PCB board. The PCB board can then complete the flipping operation. The third step involves labeling the second side of the PCB board. After flipping, the conveyor belt 461 transports the first group of PCB boards to the side of the mounting frame 42 near the second conveyor line 44. At the same time, the first conveyor line 43 can transport the second group of PCB boards to the side of the mounting frame 42 near the first conveyor line 43. In the same operation, the trigger wheel 452 on the side of the second conveyor line 44 disengages from the trigger block 45, and the corresponding gripper block 423 clamps and fixes the PCB board. The drive module 33 on the side of the second conveyor line 44 drives the support plate 332 and the support column 333 to support the underside of the PCB board. Similarly, the air nozzle 553 affixes the suction label to the second side of the PCB board. When the gripper blocks 423 clamp the PCB board, the pressure signal from the pressure sensor 425 can determine which part of the gripper blocks 423 is clamping the PCB board, thus determining the position of the PCB board. For example, if the gripper blocks 423 on the side of conveyor line 1 43 receive a pressure signal, it means that the PCB board is at the end of conveyor line 1 43. If the gripper blocks 423 on both sides of the mounting frame 42 receive a pressure signal, it means that the PCB board is in the middle of the mounting frame 42. If the gripper blocks 423 on the side of conveyor line 2 44 receive a pressure signal, it means that the PCB board is at the end of conveyor line 2 44. This avoids defective products caused by incorrect PCB board positioning. In addition, when the labeling component 5 performs the labeling operation, the bidirectional transfer module 51 moves the corresponding mating frame 52 to the corresponding PCB board position. At this time, the second motor 59 can drive the power supply rod 58 to rotate, and the corresponding electric cylinder 581 pushes the locking block 582 to engage with the inner wall of the slot 571 of the roller group 57. The corresponding slot 571 can then be driven, driving the toothed belt 573 to move, so that the slide 574 constrains and drives the air core rod 552 to move. Conversely, the locking block 582 is not engaged with the wall of the slot 571, and the corresponding electric cylinder 581 and locking block 582 rotate inside the roller group 57. This allows the position of each air core rod 552 to be maintained at different horizontal lines with the same spacing. At the corresponding PCB board, the second electric cylinder 562 only needs to push the constraint block 561 downward, driving the air core rod 552 to push the air nozzle 553 to the PCB board, which can complete the labeling operation at different horizontal lines with the same spacing on the side of the PCB board, thus speeding up the labeling efficiency of the overall labeling machine. When the air nozzle 553 moves downward with the air core rod 552 to apply the label, the motor 565 drives the gear 564 to mesh and rotate with the gear 563. The gear 563 is constrained by the constraint frame 566, which can drive the air core rod 552 and the air nozzle 553 to rotate. At the same time, the air pipe 554 moves with the air core rod 552 and is kept unobstructed by the sliding constraint of the slide rail frame 551. This also allows for synchronous adjustment and adaptation of the labeling angle, ensuring the efficiency and accuracy of labeling.
