Description

Technical Field

[0001] This invention relates to the field of PCB board processing equipment technology, and in particular to an HDI processing equipment for display screen PCB boards. Background Technology

[0002] HDI (High-Density Interconnect) technology is crucial for achieving high resolution, narrow bezels, high refresh rates, and thinness in modern displays. It is primarily used in the display's driver board and the flexible circuit board that connects to the display panel. As consumer electronics rapidly evolve towards thinner, lighter, and higher-performance products, high-density interconnect printed circuit boards have become an indispensable carrier for core modules such as displays. Manufacturing vias with tiny apertures, smooth walls, and high positional accuracy is a key technological step in their production.

[0003] Because traditional mechanical drilling has limitations in hole diameter and spacing, it is difficult to meet the processing requirements of modern ultra-thin HDI boards. Therefore, laser micro-hole processing has become the mainstream technology in the industry, offering significant advantages such as non-contact, stress-free operation, small hole diameter, and high flexibility. Currently, the laser processing solutions commonly used in the industry are usually independent stand-alone machines or segmented production lines. First, the PCB board is placed on the laser drilling machine's worktable for positioning and processing using manual labor or a simple conveyor. After drilling, the semi-finished product is transferred to another independent machine or station for post-processing to remove slag and burrs generated at the hole opening due to the high temperature of the laser.

[0004] However, the existing technical solutions have the following prominent problems that urgently need to be solved: the production process is fragmented, which limits efficiency and accuracy. The multiple loading, unloading, positioning and transfer of materials between discrete equipment not only introduces the risk of human error, making it difficult to guarantee the consistency of hole processing, but also generates a lot of non-value-added waiting time, which limits the overall production efficiency. The independent post-processing process has the problems of long processing cycle, potential environmental pollution and difficulty in matching the laser processing cycle in real time, which makes it impossible to achieve targeted online instant cleaning, affecting the final cleanliness and reliability of the hole wall.

[0005] Therefore, developing an HDI processing device that can achieve efficient laser hole making, online real-time high-quality cleaning, and fully automated integration of the entire process is an urgent practical need and of significant technical value. Summary of the Invention

[0021] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] Please see Figure 1-10As shown, this embodiment is an HDI processing device for a display PCB board, including a stand 1, a processing chamber 2 connected to the upper end of the stand 1, strip-shaped openings 3 at the left and right ends of the processing chamber 2, a conveyor frame 4 fixedly passing through the strip-shaped openings 3, a fixed arm 5 connected between the bottom wall of the conveyor frame 4 and the stand 1, a punching frame 7 connected to the top left side of the inner cavity of the processing chamber 2, a vertical cylinder 6 connected to the top right side of the processing chamber 2, a cleaning shell 8 connected to the lower end of the vertical cylinder 6, a stacking frame 9 connected to the left side wall of the processing chamber 2, and an industrial control computer 10 connected to the outer wall of the stand 1.

[0023] The conveyor frame 4 includes a front side plate 41, a rear side plate 42, a conveyor roller 43, a conveyor belt 44, a power assembly 45, and a clamping assembly 46. The outer walls of the front side plate 41 and the rear side plate 42 are both fixed with strip-shaped openings 3. The clamping assembly 46 is fixed with the inner walls of the front side plate 41 and the rear side plate 42. The left and right ends of the inner walls of the front side plate 41 and the rear side plate 42 are rotatably connected to the conveyor roller 43 through bearings. The power assembly 45 is fixed with the outer wall of the front side plate 41. It can continuously convey the PCB board through the processing chamber 2, which is convenient for HDI processing.

[0024] Multiple pusher blocks 441 are connected at equal intervals along the length of the outer wall of the conveyor belt 44. The lower end of the stacking frame 9 abuts against the upper surface of the conveyor belt 44. A clearance groove 91 that cooperates with the pusher blocks 441 is opened at the bottom of the left side wall of the stacking frame 9. A discharge port 92 is opened at the bottom of the right side wall of the stacking frame 9 to facilitate the ejection of the PCB board. Multiple infrared signal receivers 442 are connected at equal intervals along the length of the middle of the outer wall of the conveyor belt 44. A signal transmitter 20 is connected to the middle section of the top wall of the processing chamber 2 to facilitate the triggering of the corresponding component action during signal transmission.

[0025] The specific implementation method of this embodiment is as follows: When in use, this device is powered by an external power source and uses an industrial control computer 10 to control the operation of electrical components. The PCB boards to be processed are stacked in the stacking frame 9, with the bottom PCB board attached to the upper surface of the conveyor belt 44. The power component 45 drives the conveyor roller 43 to rotate, so that the pusher block 441 moves synchronously with the conveyor belt 44. When the pusher block 441 passes through the clearance groove 91 at the lower end of the stacking frame 9, it pushes the bottom PCB board out of the discharge port 92. The PCB board moves with the conveyor belt 44 through the punching frame 7 and the cleaning shell 8. When the infrared signal receiver 442 receives the signal emitted by the signal transmitter 20, it performs the corresponding HDI punching and hole cleaning on the PCB board. The processed PCB board is then discharged from the right strip port 3. Example

[0026] Based on Embodiment 1, the power assembly 45 includes a drive housing 451 fixed to the front side plate 41. A drive motor 452 is fixed to the right side of the front end face of the drive housing 451. An active dial 453 is connected to the rear output end of the drive motor 452. A lever 454 is connected to the end of the active dial 453. A driven shaft 455 is rotatably connected to the inner cavity of the drive housing 451. A grooved wheel 456 and a driven gear 457 are connected to the outer wall of the driven shaft 455. Four stroke grooves 458 are circumferentially opened on the outer wall of the grooved wheel 456. The lever 454 periodically extends into the stroke grooves 458. A pinion 459 is meshed with the left side of the driven gear 457. The center of the pinion 459 is fixed to the front end of the left conveyor roller 43, which can control the high-frequency intermittent movement of the conveyor belt 44, making it convenient to continuously feed the PCB board into the corresponding work station for processing.

[0027] Two sets of clamping assemblies 46 are provided and are located directly below the punching frame 7 and the vertical cylinder 6, respectively. The clamping assembly 46 includes a front side plate 41 and a positioning platform 461 fixed to the inner wall of the rear side plate 42. The top of the positioning platform 461 has multiple longitudinal arc grooves 462. A roller 463 is rotatably connected in the longitudinal arc grooves 462. The upper end of the roller 463 abuts against the inner wall of the conveyor belt 44. An electromagnet 464 is embedded in the center of the bottom of the positioning platform 461. A guide sleeve 465 is connected to the bottom of the positioning platform 461. A U-shaped rod 466 is movably inserted in the guide sleeve 465. A metal block 467 is connected to the lower end of the U-shaped rod 466. A clamping block 468 is connected to the upper end of the U-shaped rod 466. A return spring 469 is connected between the middle of the U-shaped rod 466 and the positioning platform 461. When the electromagnet 464 is energized, it attracts the metal block 467, which enables the clamping block 468 to clamp and fix the PCB board for processing.

[0028] Both the front side plate 41 and the rear side plate 42 have multiple through holes, and the U-shaped rod 466 and the return spring 469 pass through the through holes to avoid interfering with the forward and backward movement of the U-shaped rod 466.

[0029] The specific implementation method of this embodiment is as follows: This embodiment enables intermittent transmission and stationary movement of the conveyor belt 44. The drive motor 452 drives the active dial 453 and the lever 454 to rotate continuously. The lever 454 periodically inserts into the stroke groove 458 of the grooved wheel 456, thereby driving the grooved wheel 456 to rotate 90 degrees each time. During the operation of the grooved wheel 456, the driven shaft 455 drives the driven gear 457 to rotate. The driven gear 457 meshes with the transmission pinion 459 to make the left conveyor roller 43 rotate. When the lever 454 moves out of the stroke groove 458, the conveyor roller 43 stops, thus enabling the conveyor belt 44 to achieve precise intermittent movement. When the conveyor belt 44 is stationary, the signal transmitter 20 on the top wall of the processing chamber 2 is located directly above a set of infrared signal receivers 442. After the infrared signal receivers 442 receive the signal, the industrial control computer 10 controls the clamping assembly 46 to run and then performs HDI drilling and cleaning operations. Two sets of clamping components 46 are provided and are located directly below the punching frame 7 and the vertical cylinder 6, respectively. When the PCB board reaches the punching or cleaning station, the electromagnet 464 is energized to generate a strong magnetic force, which can attract the metal blocks 467 on the front and rear sides. The metal blocks 467 drive the U-shaped rod 466 to move against the elastic force of the return spring 469 and be guided by the guide sleeve 465. The clamping blocks 468 at the upper end of the two sets of U-shaped rods 466 move closer to each other, which can fix and clamp the PCB board. The roller 463 supports the conveyor belt 44 to prevent the conveyor belt 44 from deforming during PCB board processing, ensuring that the clamping is flat, effective and stable. After processing, the electromagnet 464 is de-energized and the return spring 469 drives the U-shaped rod 466 and the clamping block 468 back to their original positions. Example

[0030] Based on Embodiment 2, a laser generator 71 is fixedly connected to the top of the front end face of the drilling frame 7. Inside the drilling frame 7, along the optical path of the laser generator 71, a beam expander 72, a beam shaper 73, a spatial filter 74, a DOE beam splitter 75, and an adjustment cylinder 76 are arranged in sequence. The upper and lower ends of the beam expander 72 are respectively connected to a beam expander 721 and a polarization adjustment plate 722. The upper and lower ends of the inner wall of the adjustment cylinder 76 are respectively installed with a 3D galvanometer 761 and a focusing lens group 762. By using laser optical technology to drill holes using traditional mechanical methods, efficient and high-quality micro-hole processing can be achieved, ensuring the HDI processing effect.

[0031] The inner wall of the cleaning shell 8 is connected to guide rods 81 at the front and back. Sliding sleeves 82 are fitted on the outside of the guide rods 81. A lifting platform 83 is connected between the two sets of sliding sleeves 82. A linkage block 84 is connected to the bottom of the lifting platform 83. Multiple file rods 85 are connected to the lower end of the linkage block 84. A limiting shell 86 is connected to the top of the lifting platform 83. A steering motor 87 is connected to the inner wall of the cleaning shell 8. A horizontal crossbar 88 is connected to the output end of the steering motor 87. Multiple ejector cams 89 are connected to the outer wall of the horizontal crossbar 88. The upper end of the ejector cam 89 abuts against the inner wall of the limiting shell 86.

[0032] The limiting shell 86 is rectangular in shape, and the width of the inner wall of the limiting shell 86 is the same as the overall length of the top material cam 89, so as to ensure that the lifting platform 83 moves smoothly without lateral sway when the top material cam 89 rotates.

[0033] The specific implementation method of this embodiment is as follows: In this embodiment, a high-energy pulsed laser beam is emitted by a laser generator 71. After entering the beam expander 72, the beam diameter is enlarged by the beam expander 721. Then, the polarization state of the laser is adjusted by the polarization adjuster 722 to optimize the material absorption efficiency. The beam shaper 73 is used to shape the beam into a beam with a more uniform energy distribution. Subsequently, the spatial filter 74 is used to filter out stray light and improve the beam quality. The optimized single beam enters the DOE beam splitter 75 and is split into multiple sub-beams with independently controllable power and direction. These sub-beams correspond to the number and distribution requirements of the array holes, which facilitates the simultaneous processing of multiple holes in a single pulse. The processed multiple laser beams enter the adjustment tube 76. After entering the 3D galvanometer 761, the position of each sub-beam is adjusted in three-dimensional space according to the instructions of the industrial control computer 10 so that it can scan the PCB surface. Then, the sub-beams enter the adjustable focusing lens group 762. The focusing lens group adjusts the focal size and working distance according to the processing requirements to focus the beam on the workpiece surface to complete the synchronous processing of the array holes. After the HDI hole is opened, the PCB board is cleaned below the shell 8. After the PCB board is conveyed and fixed at the cleaning station, the vertical cylinder 7 drives the entire cleaning shell 8 to descend. The lifting platform 83 descends accordingly, bringing the linkage block 84 closer to the PCB board. The tips of the file bar array 85 approach the hole on the PCB board surface. The steering motor 87 drives the horizontal bar 88 to rotate, causing the long diameter end of the top material cam 89 to periodically contact the push-pull limiting shell 86. Since the limiting shell 86 is rigidly connected to the file bar 85 through the lifting platform 83 and the linkage block 84, and the whole is constrained by the guide rod 81 and the sliding sleeve 82 to only move up and down, the file bar 85 is forced to make a fast, small-amplitude up-and-down reciprocating motion, which can scrape and break the slag and burrs on the edge of the machined hole, ensuring the subsequent assembly effect of the hole. Example

A blower 22 is embedded in the top of the chip collection box 21, and a filter screen 23 is connected to the lower end of the blower 22. A dust box 24 is inserted into the front end of the chip collection box 21. A guide hose 25 connects the upper part of the rear side wall of the chip collection box 21 to the rear end of the cleaning shell 8. An inspection door 26 is installed at the front end of the processing chamber 2, and a transparent viewing window 27 is embedded in the inspection door 26. A warning light 28 is connected to the top of the processing chamber 2, and a ventilation opening 29 is opened on the left side of the top of the processing chamber 2. The specific implementation method of this embodiment is as follows: In this embodiment, the blower 22 operates continuously during HDI treatment, creating a negative pressure airflow inside the cleaning housing 8. This airflow draws debris generated during hole cleaning and draws it into the chip collection box 21 via the guide hose 25. The filter screen 23 traps the debris in the ash box 24, ensuring a clean working environment. The ventilation vent 29 helps dissipate heat from the processing chamber 2. The transparent window 27 facilitates observation of the internal operating status of the processing box 2. The warning light 28 indicates the equipment's operating or alarm status. The maintenance door 26 provides a maintenance access, ensuring effective use.
