Description

Technical Field

[0001] This invention relates to the field of PCB board processing equipment, and more specifically to an intelligent automated production line architecture for a PCB board wire bonding exposure machine. Background Technology

[0002] In recent years, the demand for PCB production has been gradually expanding. However, the current PCB manufacturing industry primarily relies on manual material handling and feeding or single automated production equipment. Manual material handling is labor-intensive, inefficient, and prone to errors and material mixing. Some single-line production line structures have extremely low production efficiency, are only suitable for one or a limited number of PCB specifications, and cannot accommodate various lengths, widths, thicknesses, or the diverse specifications required for various applications. Equipment is constrained by the single-line feeding method of the conveyor line, making it difficult to improve production efficiency. Furthermore, the entire production line has a large horizontal area, occupying a significant portion of the workshop floor space. Summary of the Invention

[0003] The problem this invention aims to solve is to provide an intelligent automated production line architecture for a PCB board interconnection exposure machine, enabling single-wafer feeding and dual-wafer positioning PCB board conveying. Utilizing a double-layer assembly line design saves floor space. PCB board transfer and flipping are smooth and safe.

[0004] To address the aforementioned problems, this invention provides an intelligent automated production line architecture for a PCB board interconnection exposure machine. To achieve the above objectives, the technical solution adopted by this invention to solve its technical problems is as follows:

[0005] An intelligent automated production line architecture for a PCB wire bonding exposure machine includes: a horizontal conveyor line for conveying PCBs, the horizontal conveyor line including an upper flow line and a lower flow line that are parallel to each other; a lifting and tilting mechanism, wherein the upper and lower flow lines are provided with lifting and tilting mechanisms at their respective adjacent ends, the lifting and tilting mechanisms having a suction cup assembly for gripping the PCBs, the suction cup assembly being fixed to a horizontal axis, the horizontal axis having vertical lifting freedom and rotational freedom around its own axis, the single rotation angle of the horizontal axis being an acute angle; an infeed / outfeed conveyor line, wherein the two ends of the lower flow line are mirror-connected with infeed / outfeed conveyor lines, the infeed / outfeed conveyor lines including a first conveyor line and a second conveyor line connected on the same horizontal plane, the width of the second conveyor line being greater than the width of the first conveyor line; and a robotic arm, wherein a robotic arm is provided on one side of the first conveyor line.

[0006] The beneficial effects of adopting the above technical solution are as follows: This technical solution facilitates intelligent control of the online exposure machine production line, integrating functions such as positioning, feeding, flipping, conveying, and transfer into a single automated online equipment. More importantly, it features a compact layout, saving space in the production workshop. The equipment uses a flipping mechanism located above the exposure machine platform, minimizing space requirements. Material handling and flipping are synchronized with the next set of robotic arms, resulting in short loading and flipping times. The equipment allows for a staggered layout of the upper and lower production lines, with a robotic arm docking design, making efficient use of vertical space and reducing the equipment footprint by half. Simultaneously, the lifting and flipping mechanism is compactly integrated with the upper and lower production lines, and its own width is also small. The material feeding mechanism almost perfectly matches the vertical projection of the lifting and flipping mechanism, without increasing the horizontal footprint. However, the lifting and flipping mechanism and the material feeding mechanism enrich the functionality of the production line. The material feeding mechanism facilitates the transfer of PCB boards between the flipping mechanism and the previous production line, enabling the PCB boards to be flipped between their front and back sides for sequential exposure.

[0007] Simultaneously, the suction cup assembly of the lifting and tilting mechanism grips the PCB board, exposing the unprocessed lower surface of the PCB board at an angle to facilitate contact between the robotic arm and the bottom surface of the PCB board for turnover. The robotic arm acts as an intermediate turnover transition, ultimately moving the PCB board to the upper flow line.

[0008] The suction cup only rotates at an acute angle because it is designed for heavy PCBs. If the rotation angle reaches an obtuse angle, the suction cup assembly will not be able to resist the weight of the PCB when it rotates 90°, which could lead to the PCB falling and being damaged.

[0009] As a further improvement of the present invention, the lifting and tilting mechanism and the robot at the same end of the horizontal conveyor line respectively contact the front and back sides of the PCB board; the two ends of the upper flow line are respectively connected to the front roller group and the rear roller group, and the lifting and tilting mechanism includes the front lifting and tilting mechanism and the back lifting and tilting mechanism; the front lifting and tilting mechanism intersects with the vertical projection of the front roller group, and the back lifting and tilting mechanism intersects with the vertical projection of the rear roller group.

The front lifting and tilting mechanism intersects with the vertical projection of the front exposure platform, and the back lifting and tilting mechanism intersects with the vertical projection of the back exposure platform.

[0011] As a further improvement of the present invention, the infeed / outfeed assembly line includes a horizontal assembly line, a clapping mechanism, and a centering mechanism; the horizontal assembly line conveys PCB boards and includes several rollers arranged at intervals. The horizontal assembly line includes a first assembly line and a second assembly line that are connected on the same horizontal plane, and the width of the second assembly line is greater than the width of the first assembly line; the clapping mechanism has a clapping rod that contacts the edge of the PCB board within the horizontal assembly line, and the clapping rod has a horizontal translational degree of freedom along the axial direction of the rollers; the centering mechanism is located within the second horizontal assembly line and has a lifting degree of freedom. The centering mechanism includes a lifting and centering vertical rod that passes through the space between adjacent rollers, and the top of the highest limit position of the lifting and centering vertical rod and the top of the clapping rod are both higher than the rollers.

[0012] As a further improvement of the present invention, a lifting mechanism is provided in the second production line, and a central mechanism is located on the lifting mechanism. The lifting mechanism includes a number of horizontally spaced lifting top bars. The length direction of the lifting top bars is parallel to the axial direction of the rollers. The lifting top bars are located between adjacent rollers, and the distance between adjacent lifting top bars is equal to the distance between adjacent rollers.

[0013] As a further improvement of the present invention, the lifting top bar has a hollow hole through which the lifting center vertical rod passes, the bottom of the lifting top bar is connected to a linear bearing, the lifting mechanism has a linear translational degree of freedom along the roller axis, the bottom of the lifting top bar is connected to a parallel linear module and a linear guide rail, and the linear module and the linear guide rail are jointly fixed to a base plate; the length of a single lifting top bar is less than the width of the first production line.

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to specific embodiments:

[0035] To achieve the objectives of this invention, an intelligent automated production line architecture for a PCB board wire bonding exposure machine is provided, comprising: a horizontal conveyor line for conveying PCB boards, the horizontal conveyor line including an upper flow line and a lower flow line that are parallel to each other; a lifting and tilting mechanism, wherein a lifting and tilting mechanism is provided between adjacent ends of the upper and lower flow lines, the lifting and tilting mechanism having a suction cup assembly for gripping the PCB boards, the suction cup assembly being fixed to a horizontal axis, the horizontal axis having a vertical lifting freedom and a rotational freedom about its own axis, the single rotation angle of the horizontal axis being an acute angle; an infeed / outfeed conveyor line, wherein the two ends of the lower flow line are mirror-connected to an infeed / outfeed conveyor line, the infeed / outfeed conveyor line including a first conveyor line and a second conveyor line that are connected on the same horizontal plane, the width of the second conveyor line being greater than the width of the first conveyor line; and a robotic arm, wherein a robotic arm is provided on one side of the first conveyor line.

[0036] The beneficial effects of adopting the above technical solution are as follows: This technical solution facilitates intelligent control of the online exposure machine production line, integrating functions such as positioning, feeding, flipping, conveying, and transfer into a single automated online equipment. More importantly, it features a compact layout, saving space in the production workshop. The equipment uses a flipping mechanism located above the exposure machine platform, minimizing space requirements. Material handling and flipping are synchronized with the next set of robotic arms, resulting in short loading and flipping times. The equipment allows for a staggered layout of the upper and lower production lines, with a robotic arm docking design, making efficient use of vertical space and reducing the equipment footprint by half. Simultaneously, the lifting and flipping mechanism is compactly integrated with the upper and lower production lines, and its own width is also small. The material feeding mechanism almost perfectly matches the vertical projection of the lifting and flipping mechanism, without increasing the horizontal footprint. However, the lifting and flipping mechanism and the material feeding mechanism enrich the functionality of the production line. The material feeding mechanism facilitates the transfer of PCB boards between the flipping mechanism and the previous production line, enabling the PCB boards to be flipped between their front and back sides for sequential exposure. Simultaneously, the suction cup assembly of the lifting and tilting mechanism grips the PCB board, exposing the unprocessed lower surface of the PCB board at an angle. This allows the robotic arm to contact the bottom surface of the PCB board, facilitating its transfer. The robotic arm acts as an intermediate transfer transition, ultimately moving the PCB board to the upper flow line. The suction cups only rotate at an acute angle to accommodate heavier PCB boards. If the rotation angle were obtuse, the suction cup assembly would be unable to withstand the weight of the PCB board at 90°, potentially causing it to fall and be damaged.

[0037] In other embodiments of the present invention, the lifting and tilting mechanism and the robot at the same end of the horizontal conveyor line respectively contact the front and back sides of the PCB board; the two ends of the upper flow line are respectively connected to the front roller group and the rear roller group, and the lifting and tilting mechanism includes the front lifting and tilting mechanism and the back lifting and tilting mechanism; the front lifting and tilting mechanism intersects with the vertical projection of the front roller group, and the back lifting and tilting mechanism intersects with the vertical projection of the rear roller group.

[0038] The beneficial effect of adopting the above technical solution is that the roller assembly and the lifting and tilting mechanism utilize the same vertical space.

[0039] In other embodiments of the present invention, the lower streamline includes an exposure machine, with a front exposure platform and a back exposure platform respectively provided at both ends of the exposure machine. The front lifting and tilting mechanism intersects with the vertical projection of the front exposure platform, and the back lifting and tilting mechanism intersects with the vertical projection of the back exposure platform.

[0040] The beneficial effects of adopting the above technical solution are: the exposure platform is a waiting area, and the exposure platform, roller group, and lifting and tilting mechanism are all in the same vertical space, which further improves the structural compactness and makes full use of the vertical space.

[0041] The material handling assembly line includes a horizontal assembly line, a clapping mechanism, and a centering mechanism. The horizontal assembly line conveys PCB boards and includes several rollers arranged at intervals. The horizontal assembly line includes a first assembly line 1 and a second assembly line 2 that are connected on the same horizontal plane. The width of the second assembly line 2 is greater than the width of the first assembly line 1. The clapping mechanism has a clapping rod that contacts the edge of the PCB board within the horizontal assembly line. The clapping rod has a horizontal translational degree of freedom along the roller axis. The centering mechanism is located within the second horizontal assembly line 2 and has a lifting degree of freedom. The centering mechanism includes a lifting and centering vertical rod 12 that passes through the space between adjacent rollers. The top of the highest limit position of the lifting and centering vertical rod 12 and the top of the clapping rod are both higher than the rollers.

[0042] The beneficial effects of adopting the above technical solution are: This technical solution realizes a single-piece feeding and dual-piece positioning PCB board conveying method, greatly improving production efficiency. The size and specifications of the PCB board are determined by sensing the position, making it suitable for various PCB board specifications with high repeatability and positioning accuracy, and providing two feeding and positioning modes. The first production line is used for single-line conveying of PCB boards, and the second production line divides the single-line PCB board into two parallel PCB boards. The clapping mechanism contacts and limits the two sides of the PCB, suitable for guiding PCBs of different widths, ensuring that the PCB is conveyed along the set position each time. When the PCB board from the single-line conveying enters the second production line, the centering mechanism lifts the PCB board, realizing the lateral displacement of the PCB to make room for the subsequent PCB boards to be arranged side by side. After the two PCB boards are arranged side by side, the lifting centering rod rises to separate the two parallel PCB boards in the second production line, preventing the two PCB boards from bumping and damaging each other. The lifting centering rod and the clapping rod of the second production line work together to achieve the limiting and fine-tuning of the position of the two parallel PCBs. Waiting for subsequent equipment to process the PCB.

[0043] In some other embodiments of the present invention, a lifting mechanism is provided in the second production line 2, and a central mechanism is located on the lifting mechanism. The lifting mechanism includes a plurality of horizontally spaced lifting top bars 6. The length direction of the lifting top bars 6 is parallel to the axial direction of the roller. The lifting top bars 6 are located between adjacent rollers, and the distance between adjacent lifting top bars 6 is equal to the distance between adjacent rollers.

[0044] The advantages of adopting the above technical solution are: the lifting mechanism and the centering mechanism are nested within each other, resulting in a compact structure. The lifting of the lifting top bar utilizes the gap between the rollers, and the two do not interfere with each other.

[0046] The advantages of adopting the above technical solution are: the hollow hole is just right for the lifting and centering vertical rod to pass through, the centering mechanism and the lifting mechanism share a single left and right translation mechanism, making the whole structure more compact and reducing costs.

[0047] In other embodiments of the invention, the length of a single lifting top bar 6 is less than the width of the first production line 1.

[0048] The beneficial effect of adopting the above technical solution is that the lifting top bar has a sufficient displacement range on both sides, which makes it easy to move the PCB board to one side.

[0049] In some other embodiments of the present invention, the second production line 2 has an end vertical bar 16 at one end away from the first production line 1, and a middle vertical bar 11 is provided at the junction of the second production line 2 and the first production line 1. Both the end vertical bar 16 and the middle vertical bar 11 have a degree of freedom to move up and down.

[0050] The beneficial effects of adopting the above technical solution are: the end vertical bar can block the PCB board in front of the conveyor in the conveying direction, controlling when the PCB board is conveyed to the downstream equipment. The middle vertical bar can independently separate the PCB boards on the first and second production lines, improving the overall control capability of the production line for each part.

[0051] In some other embodiments of the present invention, the first production line 1 and the second production line 2 are aligned on only one side along the horizontal production line conveying direction; the clapper rods include a first clapper rod 3 and a second clapper rod 4 that are parallel to each other in the first production line 1, and a third clapper rod 21 and a fourth clapper rod 22 that are parallel to each other in the second production line 2.

[0052] The beneficial effects of adopting the above technical solution are: ensuring that the two sides of the PCB board are limited, this equipment can adapt to PCB boards of different widths, and can limit and guide PCB boards of different widths to avoid the PCB board from moving left and right.

[0053] In some other embodiments of the present invention, a timing belt 24 is connected between the first clapper bar 3 and the second clapper bar 4, and a timing belt 24 is connected between the third clapper bar 21 and the fourth clapper bar 22, with the timing belt 24 located below the horizontal assembly line.

[0056] The beneficial effects of adopting the above technical solution are: the photoelectric switch is connected to the clapper rod, which enables the clapper rod to have a certain degree of automation, allowing the clapper rod to automatically sense the PCB board and automatically make contact with the PCB board for limiting.

[0057] In some other embodiments of the present invention, a boundary crossing photoelectric switch is provided below the central vertical rod 11. The boundary crossing photoelectric switch includes a first boundary crossing photoelectric switch 9 and a second boundary crossing photoelectric switch 10 located on both sides of the central vertical rod 11.

[0058] The beneficial effects of adopting the above technical solution are: the over-limit photoelectric switch also gives the middle vertical bar the ability to rise and fall. Whether it is from front to back or from back to front, the middle vertical bar has enough time to rise, instead of damaging the lower surface of the PCB board.

[0059] In some other embodiments of the present invention, the first production line 1 is composed of a plurality of first rollers 17 of equal length, and the second production line 2 is composed of a plurality of second rollers 18 of equal length, wherein the axial length of the first rollers 17 is greater than half the axial length of the second rollers 18.

[0060] The advantages of adopting the above technical solution are: the first and second production lines are designed to transport single-row and double-row PCB boards respectively, while allowing for a certain margin in the length of the rollers. Compared with conveyor belt production lines, roller production lines have more vertically penetrating space.

[0061] only Figure 4 The cover 47 is shown because the cover 47 would affect the display of the internal components.

[0062] Figure 7 and Figure 8 It is also an application diagram, showing two typical application scenarios.

[0063] To facilitate the representation of the internal structure Figure 13 The rollers are hidden inside.

[0064] like Figure 7 , Figure 8 As shown, in actual use, it first goes through Figure 8In that state, and then experience Figure 7 The state of the front PCB board 26 and the rear PCB board 26 originally had a front-to-back relationship, but... Figure 7 Then it becomes the same before and after state.

[0065] In other embodiments of the present invention, the infeed and discharge production lines are two identical infeed production lines 42 and discharge production lines 37. The infeed production line 42 is also connected to an external production line 31, the width of which is equal to the width of the second production line 2. The robotic arms include a front-side upper plate robotic arm 32 and a back-side upper plate robotic arm 36.

[0066] In some other embodiments of the present invention, a gap 43 is partially enclosed by the first production line 1 and the second production line 2, and a robotic arm is positioned at the gap 43.

[0067] In other embodiments of the invention, the lifting and tilting mechanism includes a vertical linear module 44, and a suction cup assembly 46 is fixed on a horizontal shaft 45. The entire horizontal conveyor line, lifting and tilting mechanism, and inlet / outlet assembly line are covered by a housing 47. An external assembly line 31 encloses a conveyor 48, which has an inlet 49 on its side. The housing also has an interactive display screen 50. A dust-adhesive device 34 is also provided on the upper assembly line.

[0068] The general procedure in actual use is as follows:

[0069] 1. PCB boards are transferred to the infeed / outfeed assembly line.

[0070] 2. The lifting mechanism lifts the PCB board and moves it horizontally to the set position. The lifting mechanism then lowers and places the PCB board onto the roller. 3. Following step 2, after aligning and positioning the two PCB boards, the robotic arm picks up the positioned PCB board and places it on the front exposure machine platform for exposure.

[0071] 4. After exposure is completed, the lifting and tilting mechanism picks up the exposed PCB board, lifts it up and rotates it at a certain angle to avoid the space above the exposure machine platform, so that the robot can place the second set of PCB boards.

[0072] Fifth, while the second PCB board is exposed on the platform, the robotic arm docking lifting and tilting mechanism picks up the first PCB board and places it on the upper conveyor. At this time, the PCB board has been flipped. Then, the upper conveyor conveys the PCB board through the dust removal device and arrives at the other end.

[0073] 6. The robotic arm at the other end picks up the board and places it on the exposure machine platform at the other end for exposure of the unexposed side of the PCB board.

[0074] 7. After the other side is also exposed, the lifting and tilting mechanism picks up the board that has been exposed on both sides and rotates it at a certain angle to make room, and the robotic arm places the second set of PCB boards.

[0075] 8. While the second set of PCB boards is being exposed, the lifting and tilting mechanism will continue to rotate at a certain angle and dock with the robot arm. The robot arm will then pick up the PCB board and place it on the discharge line, from which it will exit the equipment.

[0076] Then repeat the process.
