Description

Technical Field

[0001] This invention relates to the field of circuit board processing technology, and in particular to an integrated device for measuring board thickness and engraving characters. Background Technology

[0002] PCB boards are a key basic component in integrated circuit manufacturing. In the PCB board lamination process, PP is used to bond and insulate the inner core layer at high temperature, while copper foil is applied to the outer layer for subsequent pattern processing of the outer layer circuitry. To prevent the PP or copper foil from being used incorrectly due to visual similarity, after lamination, intelligent sensors are used to accurately identify the board's position, and laser measuring instruments are used to perform high-precision board thickness measurement, copper foil thickness measurement, and edge character engraving on the PCB board, thereby ensuring that the key parameters of each board are traceable and controllable.

[0003] Existing methods for measuring copper thickness, board thickness, and edge marking on PCBs cannot be performed in a continuous line, resulting in low efficiency. Furthermore, the method of determining the laser measurement position by calculating the board size and conveyor speed during board thickness measurement is problematic. In actual operation, slippage occurs between the conveyor roller and the board due to dust and oil, and the motor experiences speed fluctuations during start-up, shutdown, and speed changes. The board itself also slides due to inertia, making it impossible for the laser head to align with the preset measurement point, thus severely reducing the accuracy of board thickness measurement. Summary of the Invention

It also has the advantages of controllable cost and strong adaptability. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The integrated plate thickness measurement and engraving device disclosed in this invention is mainly used in scenarios where copper thickness and plate thickness measurement and engraving cannot be connected, resulting in low efficiency. At the same time, the plate thickness measurement is easily affected by slippage and speed fluctuations, which can cause laser positioning inaccuracy and reduce the accuracy of plate thickness measurement.

[0020] Reference Figures 1-10 A sheet metal thickness measurement and engraving integrated device, comprising: An integrated tooling cabinet 1 has tooling vertical bars 7 arranged at equal intervals on the top of the integrated tooling cabinet 1.

A laser head 511 is provided on one side of the follow-up synchronous measuring frame 504. Two support plates 512 are fixedly connected to one side of the laser head 511.

Multiple adaptive cylinders 508 are equidistantly slidably connected to one side of the lifting clamping plate 507. One end of each of the multiple adaptive cylinders 508 is fixedly connected to a rubber base 509. The same telescopic spring 510 is fixedly connected to the opposite side of the adaptive cylinders 508 and the lifting clamping plate 507. The telescopic spring 510 is located outside the adaptive cylinders 508.

[0023] Reference Figures 1-10 In a preferred embodiment, the follow-up synchronous measurement module 5 further includes: Two laser-triggered racks 518 are fixedly connected to one side of two limiting rails 501 respectively. The follower slider 503 is fixedly connected to the same follower return spring 515 on the opposite side of the limiting rail 501. The follower return spring 515 is located outside the guide rod 502. Two gear shafts 516 are connected to both sides of the follow-up synchronous measuring frame 504 via bearings. Trigger gears 517 are fixedly connected to the outside of each gear shaft 516. The trigger gears 517 mesh with the laser trigger rack 518. One end of each gear shaft 516 is provided with a trigger paddle 1 519 and a trigger paddle 2 521. Photoelectric trigger switch groups 520 are provided on one side of each of the two tooling crossbars 9.

[0024] Specifically, after the equipment is started, the PCB board enters from the feeding end of the integrated tooling cabinet 1. When the board reaches the detection area of ​​the feeding sensor 11, the feeding sensor 11 sends a board presence signal to the controller 4. The controller 4 then controls the two baffle lifting cylinders 22 to drive the baffle 23 to rise, physically stopping the board at the front end. At the same time, the conveying roller 10 stops rotating after receiving the baffle arrival signal, so that the board stops precisely at the preset initial processing position. After the board is stopped by the baffle 23, multiple electric telescopic cylinders 17 set above the integrated tooling cabinet 1 drive the board guide wheel 18 to rise, lifting the board from below. At the same time, the bidirectional electric telescopic cylinder 21 set between the two support plates 19 drives the two side plate supports 16 to slide towards each other along the guide cylinder 20. The movement pushes the plate to the center position in the horizontal direction, ensuring that the positioning reference for subsequent copper thickness measurement and engraving is consistent. After the plate is fixed in the center, the copper thickness measuring mechanism 13, which is set on the two tooling crossbars 9, is activated. Its measuring head contacts the upper and lower surfaces of the plate respectively to complete the data acquisition of copper foil thickness. After the copper thickness measurement is completed, the laser engraving mechanism 14 is activated, and the laser generator 15 generates a laser beam to engrave characters on the upper surface of the plate. After the laser engraving is completed, the controller 4 sends a descent command to the baffle lifting cylinder 22. The baffle 23 descends and resets, and the conveying roller 10 restarts, conveying the plate towards the discharge end. At the moment the plate starts to be conveyed, the follow-up synchronous measurement module 5 enters the working state. The two follow-up synchronous measurement modules 504 are set on the follow-up synchronous measurement frame 504. Simultaneously, the telescopic cylinder 506 extends its drive end downward, pushing the lifting clamping plate 507 downward along the two lifting limit rods 505. During the downward movement of the lifting clamping plate 507, the rubber bases 509 at the ends of the multiple adaptive cylinders 508 on its lower surface gradually approach and finally press against the upper surface of the plate. During this process, due to the elastic material properties of the rubber bases 509 and the fact that each adaptive cylinder 508 is fitted with a telescopic spring 510, when there is slight warping or unevenness on the surface of the plate, each adaptive cylinder 508 can be independently compressed or extended, so that each rubber base 509 can tightly fit against the surface of the plate, forming multi-point uniform pressing. The telescopic spring 510 provides continuous downward pressure to the adaptive cylinders 508, ensuring that the rubber bases 509... Sufficient static friction is generated between the rubber base 509 and the plate. Once a stable static friction contact is established between the rubber base 509 and the upper surface of the plate, the follower synchronous measuring frame 504 is slidably connected to the guide rod 502 via the follower slider 503, forming a floating support structure that can move freely along the conveying direction. At this time, when the plate moves forward, the static friction between the rubber base 509 and the plate directly drags the entire follower synchronous measuring frame 504 forward synchronously along the two limit tracks 501. The moving speed of the follower synchronous measuring frame 504 is completely consistent with the moving speed of the plate, and the moving distance is always equal to the actual moving distance of the plate, regardless of whether the conveyor roller 10 slips, whether the speed of the conveyor drive motor fluctuates, or whether the plate has inertial slippage.As the follow-up synchronous measuring frame 504 is dragged along the guide rod 502 by the plate, two gear shafts 516 on both sides of the follow-up synchronous measuring frame 504 move synchronously with the measuring frame. A trigger gear 517 fixedly connected to each gear shaft 516 maintains constant mesh with a laser trigger rack 518 fixed to one side of the limit track 501. When the measuring frame moves, the trigger gear 517 rolls on the laser trigger rack 518. The rotation angle of the gear shaft 516 has a strict linear relationship with the moving distance of the measuring frame. This relationship is determined by the pitch circle circumference of the gear and the tooth pitch of the rack, without any electronic integration or time variables. A trigger lever 1 519 and a trigger lever 2 52 are fixedly installed at one end of each gear shaft 516. 1. The installation angle of the two levers on the gear shaft 516 is preset according to the preset plate thickness measurement point position. At the same time, photoelectric trigger switch group 520 is set at the corresponding position on one side of the two tooling crossbars 9. When the follow-up synchronous measuring frame 504 starts to move from the initial position, the gear shaft 516 starts to rotate from zero angle. When the measuring frame moves a distance to the first preset value, such as the position of the first measurement point on the plate, the gear shaft 516 rotates to the set angle of the trigger lever 519. The trigger lever 519 just triggers the corresponding switch in the photoelectric trigger switch group 520. The switch sends a trigger signal to the controller 4. The controller 4 then collects the measurement data of the laser head 511 set on the follow-up synchronous measuring frame 504. When the measurement... When the frame continues to move to the second preset distance, the gear shaft 516 continues to rotate to the set angle of the trigger lever 521. The trigger lever 521 actuates another switch in the photoelectric trigger switch group 520, triggering the laser head 514 to collect plate thickness data. It should be noted that both the laser head 511 and the laser head 514 are fixedly mounted on the follow-up synchronous measuring frame 504 via the support plate 512 and the tooling rod 513. Their positions relative to the measuring frame itself are fixed. However, since the measuring frame moves synchronously with the plate, the triggering time is precisely determined by the mechanical displacement. Therefore, the two measurements correspond to two different points on the plate with fixed physical positions. Since the trigger signal comes entirely from the mechanical rotation angle of the gear shaft 516, and this angle is only related to... The physical displacement of the measuring frame is related to the rotational speed of the conveyor roller 10, the instantaneous speed of the motor, and the sliding state of the plate. Therefore, the actual physical positions of the multiple measuring points on the plate, configured according to the number of laser heads, remain constant and are unaffected by any conveying interference factors, fundamentally ensuring the accuracy of plate thickness measurement. After the follow-up synchronous measuring frame 504 completes data acquisition from all preset measuring points, the controller 4 sends a lifting command to the telescopic cylinder 506. The telescopic cylinder 506 drives the lifting clamping plate 507 to rise, and the rubber base 509 detaches from the upper surface of the plate. At this time, the static friction connection between the follow-up synchronous measuring frame 504 and the plate is released, and under the elastic restoring force of the follow-up return spring 515...The follower slider 503 drives the follower synchronous measuring frame 504 to slide back to its initial position along the guide rod 502. Simultaneously, the trigger gear 517 rolls in the opposite direction on the laser trigger rack 518, and trigger paddles 1 and 2 simultaneously reset, awaiting the arrival of the next board. After the board completes all processes of copper thickness measurement, engraving, and board thickness measurement, it continues to be conveyed to the discharge end by the conveyor roller 10. When the board reaches the board discharge sensor 12 at the discharge end, the board discharge sensor 12 sends a board discharge signal to the controller 4, completing the entire processing and inspection process for that board. In specific application scenarios, this invention integrates the copper thickness measurement mechanism 13, the laser engraving mechanism 14, and the follow-up synchronous measurement module 5 onto the same equipment along the board conveying direction by setting a gantry-type support frame composed of a tooling vertical rod 7 and a tooling horizontal rod 9 above the integrated tooling cabinet 1. Driven by the conveying roller 10, the board can continuously complete the three processes of copper thickness measurement, laser engraving, and board thickness measurement on the same equipment, eliminating the need for manual transfer and secondary positioning between different devices. Compared to the traditional multi-station operation mode, this invention significantly reduces the board loading and unloading time and turnover time, and reduces the frequency of manual intervention. This invention significantly improves the overall production efficiency of PCB board inspection and marking. It abandons the traditional control method of calculating the laser measurement position by integrating conveyor speed and conveyor time in board thickness measurement. Instead, it uses a follow-up synchronous measuring frame 504 and a telescopic cylinder 506 to drive the lifting clamping plate 507 downwards. This causes the rubber bases 509 at the ends of multiple adaptive cylinders 508 to press against the upper surface of the board. Static friction causes the follow-up synchronous measuring frame 504 to be directly dragged forward by the board. During this process, the displacement of the follow-up synchronous measuring frame 504 is strictly equal to the actual displacement of the board, with no cumulative error. Even during transport... When the feeding roller 10 slips due to dust or oil, or when the conveyor drive motor experiences speed fluctuations during start-up, shutdown, or speed changes, or when the sheet material slips due to inertia and impact, the displacement of the follow-up synchronous measuring frame 504 remains consistent with that of the sheet material itself, physically isolating the interference of unstable factors in the conveying system on the measurement and positioning. Gear shafts 516 and trigger gears 517 are installed on both sides of the follow-up synchronous measuring frame 504, meshing with a laser trigger rack 518 fixed on the limit track 501. When the follow-up synchronous measuring frame 504 moves, the rotation angle of the trigger gear 517 has a precise linear relationship with the displacement, without any electronic interference. The delay or speed conversion error is mitigated by installing trigger paddle 1 519 and trigger paddle 2 521 at a preset angle on the gear shaft 516 and cooperating with the photoelectric trigger switch group 520 to achieve mechanical trigger sampling of laser head 1 511 and laser head 2 514. This triggering method does not depend on the timing accuracy of the controller, the pulse count of the encoder, or the stability of the speed feedback signal. Its positioning accuracy is determined only by the machining accuracy of the trigger gear 517 and the laser trigger rack 518 and the installation angle accuracy of trigger paddle 1 519 and trigger paddle 2 521. There is no electrical drift or software accumulation error after long-term use.Multiple adaptive cylinders 508, evenly spaced below the lifting clamping plate 507, are each independently equipped with a telescopic spring 510 and a rubber base 509 at their ends. When pressing on plates of different thicknesses or with slightly warped surfaces, each adaptive cylinder 508 can independently extend and retract according to the actual local height of the plate, ensuring that all rubber bases 509 simultaneously contact the plate surface and form a uniformly distributed clamping force. This structure ensures a reliable static friction connection between the follow-up synchronous measuring frame 504 and the plate, preventing relative slippage due to insufficient clamping force at a single point, and also avoids indentations or damage to the plate surface caused by rigid clamping. Furthermore, it is compatible with PCBs of different thicknesses, improving the equipment's versatility.

[0026] Reference Figures 1-5 In a preferred embodiment, the cleaning module 6 further includes: Two cleaning limit posts 606 are symmetrically slidably connected to one side of the cleaning horizontal plate 602. One end of the two cleaning limit posts 606 is fixedly connected to the same U-shaped lifting frame 604. One side of the U-shaped lifting frame 604 is fixedly connected to the drive end of the electric telescopic rod 603. The cleaning brush cylinder 605 is connected to the U-shaped lifting frame 604 via a bearing.

[0027] Specifically, during continuous operation, the equipment periodically or as needed activates the cleaning module 6. Two electric telescopic rods 603 set on the cleaning horizontal plate 602 drive the U-shaped lifting frame 604 to descend along the cleaning limit post 606, so that the cleaning brush cylinder 605 contacts the upper surface of the plate. As the plate is conveyed, the cleaning brush cylinder 605 removes dust and oil stains from the surface of the plate, reducing the adverse effects of foreign objects on subsequent measurement and conveying friction, and further improving the stability of follow-up synchronous measurement.

Two side frames 2 are symmetrically positioned above the integrated tooling cabinet 1.

[0032] Working principle: After the equipment is started, the PCB board enters from the feeding end of the integrated tooling cabinet 1. When the board reaches the detection area of ​​the feeding sensor 11, the feeding sensor 11 sends a board presence signal to the controller 4. The controller 4 then controls the two baffle lifting cylinders 22 to drive the baffle 23 to rise, physically stopping the board at the front end. At the same time, the conveying roller 10 stops rotating after receiving the baffle arrival signal, so that the board stops precisely at the preset initial processing position. After the board is stopped by the baffle 23, multiple electric telescopic cylinders 17 set above the integrated tooling cabinet 1 drive the board guide wheel 18 to rise, lifting the board from below. At the same time, the bidirectional electric telescopic cylinder 21 set between the two support plates 19 drives the two side plate supports 16 to slide towards each other along the guide cylinder 20. The movement pushes the plate to the center position in the horizontal direction, ensuring that the positioning reference for subsequent copper thickness measurement and engraving is consistent. After the plate is fixed in the center, the copper thickness measuring mechanism 13, which is set on the two tooling crossbars 9, is activated. Its measuring head contacts the upper and lower surfaces of the plate respectively to complete the data acquisition of copper foil thickness. After the copper thickness measurement is completed, the laser engraving mechanism 14 is activated, and the laser generator 15 generates a laser beam to engrave characters on the upper surface of the plate. After the laser engraving is completed, the controller 4 sends a descent command to the baffle lifting cylinder 22. The baffle 23 descends and resets, and the conveying roller 10 restarts, conveying the plate towards the discharge end. At the moment the plate starts to be conveyed, the follow-up synchronous measurement module 5 enters the working state. The two follow-up synchronous measurement modules 504 are set on the follow-up synchronous measurement frame 504. Simultaneously, the telescopic cylinder 506 extends its drive end downward, pushing the lifting clamping plate 507 downward along the two lifting limit rods 505. During the downward movement of the lifting clamping plate 507, the rubber bases 509 at the ends of the multiple adaptive cylinders 508 on its lower surface gradually approach and finally press against the upper surface of the plate. During this process, due to the elastic material properties of the rubber bases 509 and the fact that each adaptive cylinder 508 is fitted with a telescopic spring 510, when there is slight warping or unevenness on the surface of the plate, each adaptive cylinder 508 can be independently compressed or extended, so that each rubber base 509 can tightly fit against the surface of the plate, forming multi-point uniform pressing. The telescopic spring 510 provides continuous downward pressure to the adaptive cylinders 508, ensuring that the rubber bases 509... Sufficient static friction is generated between the rubber base 509 and the plate. Once a stable static friction contact is established between the rubber base 509 and the upper surface of the plate, the follower synchronous measuring frame 504 is slidably connected to the guide rod 502 via the follower slider 503, forming a floating support structure that can move freely along the conveying direction. At this time, when the plate moves forward, the static friction between the rubber base 509 and the plate directly drags the entire follower synchronous measuring frame 504 forward synchronously along the two limit tracks 501. The moving speed of the follower synchronous measuring frame 504 is completely consistent with the moving speed of the plate, and the moving distance is always equal to the actual moving distance of the plate, regardless of whether the conveyor roller 10 slips, whether the speed of the conveyor drive motor fluctuates, or whether the plate has inertial slippage.As the follow-up synchronous measuring frame 504 is dragged along the guide rod 502 by the plate, two gear shafts 516 on both sides of the follow-up synchronous measuring frame 504 move synchronously with the measuring frame. A trigger gear 517 fixedly connected to each gear shaft 516 maintains constant mesh with a laser trigger rack 518 fixed to one side of the limit track 501. When the measuring frame moves, the trigger gear 517 rolls on the laser trigger rack 518. The rotation angle of the gear shaft 516 has a strict linear relationship with the moving distance of the measuring frame. This relationship is determined by the pitch circle circumference of the gear and the tooth pitch of the rack, without any electronic integration or time variables. A trigger lever 1 519 and a trigger lever 2 52 are fixedly installed at one end of each gear shaft 516. 1. The installation angle of the two levers on the gear shaft 516 is preset according to the preset plate thickness measurement point position. At the same time, photoelectric trigger switch group 520 is set at the corresponding position on one side of the two tooling crossbars 9. When the follow-up synchronous measuring frame 504 starts to move from the initial position, the gear shaft 516 starts to rotate from zero angle. When the measuring frame moves a distance to the first preset value, such as the position of the first measurement point on the plate, the gear shaft 516 rotates to the set angle of the trigger lever 519. The trigger lever 519 just triggers the corresponding switch in the photoelectric trigger switch group 520. The switch sends a trigger signal to the controller 4. The controller 4 then collects the measurement data of the laser head 511 set on the follow-up synchronous measuring frame 504. When the measurement... When the frame continues to move to the second preset distance, the gear shaft 516 continues to rotate to the set angle of the trigger lever 521. The trigger lever 521 actuates another switch in the photoelectric trigger switch group 520, triggering the laser head 514 to collect plate thickness data. It should be noted that both the laser head 511 and the laser head 514 are fixedly mounted on the follow-up synchronous measuring frame 504 via the support plate 512 and the tooling rod 513. Their positions relative to the measuring frame itself are fixed. However, since the measuring frame moves synchronously with the plate, the triggering time is precisely determined by the mechanical displacement. Therefore, the two measurements correspond to two different points on the plate with fixed physical positions. Since the trigger signal comes entirely from the mechanical rotation angle of the gear shaft 516, and this angle is only related to... The physical displacement of the measuring frame is related to the rotational speed of the conveyor roller 10, the instantaneous speed of the motor, and the sliding state of the plate. Therefore, the actual physical positions of the multiple measuring points on the plate, configured according to the number of laser heads, remain constant and are unaffected by any conveying interference factors, fundamentally ensuring the accuracy of plate thickness measurement. After the follow-up synchronous measuring frame 504 completes data acquisition from all preset measuring points, the controller 4 sends a lifting command to the telescopic cylinder 506. The telescopic cylinder 506 drives the lifting clamping plate 507 to rise, and the rubber base 509 detaches from the upper surface of the plate. At this time, the static friction connection between the follow-up synchronous measuring frame 504 and the plate is released, and under the elastic restoring force of the follow-up return spring 515...The follower slider 503 drives the follower synchronous measuring frame 504 to slide back to the initial position along the guide rod 502. Simultaneously, the trigger gear 517 rolls in the opposite direction on the laser trigger rack 518, and trigger paddles 1 and 2 reset synchronously, awaiting the arrival of the next board. After the board completes all processes of copper thickness measurement, engraving, and board thickness measurement, it continues to be conveyed to the discharge end by the conveyor roller 10. When the board reaches the board discharge sensor 12 at the discharge end, the board discharge sensor 12 sends a board discharge signal to the controller 4, completing the entire processing and inspection process for the board. During continuous operation, the equipment periodically or as needed activates the cleaning module 6. Two electric telescopic rods 603, mounted on the cleaning horizontal plate 602, drive the U-shaped lifting frame 604 to descend along the cleaning limit post 606, causing the cleaning brush cylinder 605 to contact the upper surface of the board. As the board is conveyed, the cleaning brush cylinder 605 removes dust and oil from the board surface, reducing the adverse effects of foreign objects on subsequent measurements and conveying friction, further improving the stability of the follower synchronous measurement.
