Description

TECHNICAL FIELD

[0001] The application relates to the technical field of PCB production, in particular to an LDI exposure machine with self-adaptive alignment and uniform exposure functions. BACKGROUND

[0002] A PCB (Printed Circuit Board) is a core and basic component of an electronic device, takes an insulating substrate as a carrier, forms a specific pattern of copper foil lines on the surface or inside of the substrate through printing, etching and other processes, and realizes the mechanical support and electrical connection functions of electronic components by means of pads, vias and other structures. It is like the "skeleton" and "blood vessels" of an electronic device, can orderly fix scattered components such as resistors, capacitors and chips, ensure accurate transmission of current and signals, reduce manual wiring errors, improve production efficiency and product reliability, and is a key guarantee for the miniaturization and integration of modern electronic products. The core reason for using an LDI exposure machine in PCB production is that modern electronic devices have increasingly high requirements for PCB line precision. Traditional exposure technology relies on physical film, which is prone to problems such as size deformation and alignment deviation, and is difficult to meet the production needs of fine lines. The LDI exposure machine uses laser direct imaging technology, does not require film, can achieve micron-level alignment accuracy and high resolution, and can shorten the production cycle and reduce costs. The core production process of the LDI exposure machine includes: the LDI exposure machine receives designed CAD data, projects line patterns on the photosensitive layer through a laser beam and completes exposure, removes unhardened photosensitive glue after exposure through development, removes the copper layer without photosensitive glue protection through etching process, and finally forms accurate copper foil lines.

[0003] When the existing exposure machine performs exposure processing on the PCB, the PCB can be conveyed to the exposure unit by a conveyor, and the PCB can be exposed and processed by the exposure unit. However, when the PCB is produced for a long time, dust will inevitably exist in the workshop. As the PCB is conveyed, dust will inevitably adhere to the PCB. Dust or impurities will block the emitted laser during exposure, causing pinholes and open circuits in the exposed pattern, which is not conducive to the production of the PCB. SUMMARY

[0004] The purpose of the present application is to solve the problem of dust in the workshop during long-term production of the PCB, which will inevitably adhere to the PCB during conveying of the PCB, and dust or impurities will block the emitted laser during exposure, causing pinholes and open circuits in the exposed pattern, which is not conducive to the production of the PCB. The present application provides an LDI exposure machine with self-adaptive alignment and uniform exposure functions.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution: An LDI exposure machine with adaptive alignment and uniform exposure functions includes a conveyor first, a cleaning chamber fixedly connected to one side of the conveyor first, an exposure chamber fixedly connected to one side of the cleaning chamber, an immersion tank installed on one side of the exposure chamber, a conveyor second installed at one end of the immersion tank, grooves opened on both sides of the interior of the cleaning chamber, alignment components installed inside the grooves, symmetrical cleaning components installed inside the cleaning chamber, the cleaning components and alignment components being drivenly connected, a dust extraction assembly fixedly connected to one side of the cleaning chamber, the suction end of the dust extraction assembly located inside the cleaning chamber, clamps installed inside the exposure chamber, and laser emitting units fixedly connected to the upper and lower sides of the interior of the exposure chamber, a discharge component installed inside the immersion tank, and a conveyor connected between the exposure chamber and the immersion tank.

[0006] By adopting the above technical solution, when the internal components of the alignment component are transporting the PCB board, the internal components can simultaneously drive multiple cleaning components, causing the internal components of the cleaning components to run. At this time, the alignment component can drive the PCB board to pass through the cleaning components. The running cleaning components can clean both sides of the PCB board, further removing dust or impurities adhering to the surface, reducing the possibility of surface dust blocking the laser and causing pinholes or open circuits in the exposure pattern, and further improving the quality of exposure production.

[0007] Furthermore, the alignment component includes a slider slidably installed inside a slide groove. An electric guide rail is installed on one side of the slide groove. The electric guide rail is driven and connected to the slider. Both ends of the slider are fixedly connected to racks. An electric push rod three is fixedly connected to the middle of one side of the slider. Symmetrical telescopic rods are fixedly connected to one side of the slider. A soft rubber clamp is fixedly connected to one end of the electric push rod three.

[0008] By adopting the above technical solution, the operation of the electric push rod three pushes the soft rubber clamp to move, so that the soft rubber clamp moves towards the PCB board. The two soft rubber clamps push and clamp the PCB board.

[0009] Furthermore, the cleaning component includes a rotating shaft rotatably connected inside a conveyor, with gears fixedly connected to both ends of the rotating shaft, soft brush cylinders fixedly connected to the gears, and the gears meshing with a rack.

[0010] By adopting the above technical solution, the PCB board can be cleaned by rotating the soft brush tube, thus removing the dust and impurities adhering to the PCB board.

[0011] Furthermore, the dust extraction assembly includes a dust extraction component fixedly connected to one side of the cleaning chamber. One end of the dust extraction component is fixedly connected to a connecting pipe, and both ends of the connecting pipe are fixedly connected to air vents. Multiple suction pipes are fixedly connected to the air vents, and a dust collection hood is fixedly connected to the suction pipes.

[0012] By adopting the above technical solution, the dust generated by the soft brush tube is extracted by the dust collection hood, and the dust is sent into the dust collection device through the suction pipe, air pipe and connecting pipe.

[0013] Furthermore, the dust collection device includes a dust collection box fixedly connected to one side of the cleaning chamber, a filter screen fixedly connected to one side of the dust collection box, and a baffle slidably connected to the other side of the dust collection box. An air pump is fixedly connected to the side of the dust collection box away from the baffle, and the air pump's suction end is connected to a connecting pipe.

[0014] By adopting the above technical solution, the filter screen can block dust in the air and keep it in the dust collection box.

[0015] Furthermore, guide grooves are provided on both sides of the inside of the exposure chamber, and an electric push rod is fixedly connected to one end of the guide groove, and a gripper is fixedly connected to one end of the electric push rod.

[0016] By adopting the above technical solution, the PCB board can be clamped by two grippers, and the fixed PCB board can be moved by an electric push rod.

[0017] Furthermore, a servo motor is fixedly connected to one side of the top of the soaking tank, a threaded rod is fixedly connected to the output end of the servo motor, and a guide rod is fixedly connected to the inner corner of the soaking tank. The threaded rod is connected to the discharge component in a transmission connection.

[0018] By adopting the above technical solution, the operation of the servo motor can drive the threaded rod to rotate, which in turn drives the material discharge component to move.

[0019] Furthermore, the discharge component includes a support seat threadedly connected to a threaded rod, a connecting seat rotatably connected to one end of the support seat, a receiving mesh box fixedly connected to one side of the connecting seat, and an electric actuator two hinged between the connecting seat and the support seat.

[0020] By adopting the above technical solution, the connecting seat is positioned on top by the operation of the electric push rod two, causing the connecting seat to rotate around the rotation point, thereby driving the receiving mesh box to rotate, so that the PCB board in the receiving mesh box can be poured onto the conveyor two.

[0021] In summary, this application includes at least one of the following beneficial effects; 1. In this application, when a pair of PCB boards are conveyed to the cleaning chamber via a conveyor, the operation of the alignment component allows the internal components of the alignment component to push the PCB board, adjust it to the center position, and clamp the PCB board by the internal components of the alignment component, thereby achieving alignment adjustment of the PCB board. The continuous pushing of the alignment component stably conveys the PCB board into the exposure chamber, where the internal components of the exposure chamber connect and convey the PCB board, thereby accurately conveying the PCB board to the laser emitting unit. This achieves self-adaptive alignment of the PCB board and improves the quality of PCB board exposure production.

[0022] 2. In this application, when the internal components of the alignment component are transporting the PCB board, the internal components can simultaneously drive multiple cleaning components, causing the internal components of the cleaning components to run. At this time, the alignment component can drive the PCB board to pass through the cleaning components. The running cleaning components can clean both sides of the PCB board, further removing dust or impurities adhering to the surface, reducing the possibility of surface dust blocking the laser and causing pinholes or open circuits in the exposure pattern, and further improving the quality of exposure production.

[0023] 3. In this application, when the cleaning component brushes both sides of the PCB board, the dust extraction component can operate synchronously, so that the internal components of the dust extraction component are driven to extract the air inside the cleaning chamber, thereby extracting the dust generated during the cleaning process, further cleaning the dust and impurities, reducing the possibility of dust and impurities falling onto the PCB board again, improving the cleaning quality, and thus improving the exposure production quality.

[0024] 4. In this application, after the PCB board is exposed by the laser emitting unit, it can be introduced into the immersion tank by a conveyor, so that the PCB board is immersed in the developing solution inside the immersion tank and falls into the discharge component. When it is necessary to remove the PCB board, the discharge component can be driven by the internal components of the immersion tank, so that the discharge component is lifted out of the developing solution, and the PCB board is poured onto the second conveyor by the internal components of the discharge component, so that the PCB board can be retrieved. During this process, no manual retrieval is required, the operation is convenient and safe, and the production efficiency of PCB board is improved. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0028] This application discloses an LDI exposure machine with adaptive alignment and uniform exposure functions.

[0029] Reference Figure 1 and Figure 3 An LDI exposure machine with adaptive alignment and uniform exposure functions includes a conveyor 1, a cleaning chamber 2 fixedly connected to one side of the conveyor 1, an exposure chamber 3 fixedly connected to one side of the cleaning chamber 2, an immersion tank 4 installed on one side of the exposure chamber 3, a conveyor 5 installed at one end of the immersion tank 4, grooves 21 opened on both sides of the interior of the cleaning chamber 2, alignment components 6 installed inside the grooves 21, symmetrical cleaning components 8 installed inside the cleaning chamber 2, the cleaning components 8 and alignment components 6 being connected by a transmission, a dust extraction component 7 fixedly connected to one side of the cleaning chamber 2, the suction end of the dust extraction component 7 being located inside the cleaning chamber 2, clamps installed inside the exposure chamber 3, and laser emitting units 31 fixedly connected to both the upper and lower sides of the interior of the exposure chamber 3, a discharge component 44 provided inside the immersion tank 4, a conveyor 9 provided between the exposure chamber 3 and the immersion tank 4, guide grooves opened on both sides of the interior of the exposure chamber 3, an electric push rod 32 fixedly connected to one end of the guide groove, and a gripper 33 fixedly connected to one end of the electric push rod 32.

[0030] When performing PCB exposure production, the PCB is first placed on conveyor 1. Conveyor 1 transports the PCB to cleaning chamber 2. Then, the alignment component 6 pushes the PCB to its center position and clamps it, achieving alignment. After clamping, the PCB is transported to exposure chamber 3, where it is clamped by two grippers 33. The electric push rod 32 moves the grippers 33, moving the PCB to laser emitting unit 31. The PCB is then exposed to laser light from both sides. The emitting unit 31 can perform exposure processing on the PCB board, thus realizing the exposure production of the PCB board. After exposure, the gripper 33 moves the PCB board to the conveyor 9 and releases the gripper 33 from the PCB board. Then, the PCB board is transported to the immersion tank 4 by the operation of the conveyor 9 and falls into the discharge component 44. During this process, the PCB board is immersed in the developing solution inside the immersion tank 4. When it is necessary to pick up the PCB board, the internal components of the immersion tank 4 can drive the discharge component 44 to lift the discharge component 44 upward, causing the PCB board to separate from the developing solution. Then, the operation of the discharge component 44 will pour the PCB board onto the second conveyor 5, and the operation of the second conveyor 5 will transport the PCB board to the subsequent processing mechanism.

[0031] When the internal components of the alignment component 6 are moving to transport the PCB board, they can simultaneously drive multiple cleaning components 8, causing the internal components of the cleaning components 8 to move. At this time, the alignment component 6 can drive the PCB board past the cleaning components 8. The moving cleaning components 8 can clean both sides of the PCB board, further removing dust or impurities adhering to the surface. When the cleaning components 8 are cleaning both sides of the PCB board, the dust extraction component 7 can operate simultaneously, causing the internal components of the dust extraction component 7 to be driven. The internal components of the dust extraction component 7 extract the air inside the cleaning chamber 2, thereby extracting the dust generated during the cleaning of the cleaning components 8, further cleaning the dust and impurities, and reducing the possibility of dust and impurities falling onto the PCB board again.

[0032] Reference Figure 2 and Figure 6The alignment component 6 includes a slider 61 that is slidably installed inside the slide groove 21. An electric guide rail 66 is installed on one side of the slide groove 21. The electric guide rail 66 is driven to connect with the slider 61. Both ends of the slider 61 are fixedly connected to racks 65. An electric push rod 62 is fixedly connected to the middle of one side of the slider 61. Symmetrical telescopic rods 64 are fixedly connected to one side of the slider 61. A soft rubber clamp 63 is fixedly connected to one end of the electric push rod 62.

[0033] When the PCB board is transported to the cleaning chamber 2, the operation of the electric push rod 62 can move the soft rubber clamp 63, causing the soft rubber clamp 63 to move towards the PCB board. The two soft rubber clamps 63 push and clamp the PCB board. Then, the operation of the electric guide rail 66 can drive the slider 61 to slide in the slide groove 21, thereby moving the fixed PCB board and accurately transporting the PCB board to the laser emitting unit 31, thus achieving self-adaptive alignment of the PCB board. In addition, when the slider 61 moves, it can drive the rack 65 to move synchronously, and the movement of the rack 65 can synchronously drive the cleaning component 8.

[0034] Reference Figure 4 The cleaning component 8 includes a rotating shaft 81 rotatably connected inside the conveyor 1. Gears 82 are fixedly connected to both ends of the rotating shaft 81. A soft brush cylinder 83 is fixedly connected to the gear 82. The gear 82 meshes with the rack 65.

[0035] The movement of rack 65 drives gear 82 to rotate, which in turn drives shaft 81 to rotate. The rotating shaft 81 drives soft brush cylinder 83 to rotate, and the rotating soft brush cylinder 83 can clean the PCB board, thus removing dust and impurities adhering to the PCB board.

[0036] Reference Figure 7 and Figure 8 The dust extraction assembly 7 includes a dust extraction component 71 fixedly connected to one side of the cleaning chamber 2. One end of the dust extraction component 71 is fixedly connected to a connecting pipe 72, and both ends of the connecting pipe 72 are fixedly connected to air pipes 73. Multiple suction pipes 74 are fixedly connected to the air pipes 73, and dust collection hoods 75 are fixedly connected to the suction pipes 74. The dust extraction component 71 includes a dust collection box 711 fixedly connected to one side of the cleaning chamber 2. A filter screen 714 is fixedly connected to one side of the dust collection box 711, and a baffle 713 is slidably connected to the other side of the dust collection box 711. An air pump 712 is fixedly connected to the side of the dust collection box 711 away from the baffle 713, and the suction end of the air pump 712 is connected to the connecting pipe 72.

[0037] By operating the air pump 712, air can be drawn from the inside of the connecting pipe 72, creating negative pressure inside the vent pipe 73, the suction pipe 74, and the dust collection hood 75. Then, the dust generated by the soft brush cylinder 83 is extracted through the dust collection hood 75 and sent to the dust collection box 711 through the suction pipe 74, the vent pipe 73, and the connecting pipe 72. The filter screen 714 can block the dust in the air and keep it in the dust collection box 711, thereby adsorbing and cleaning the dust generated by brushing and reducing the possibility of secondary contamination of the PCB board by dust or impurities. In addition, the dust collection box 711 can be opened by manually pulling the baffle 713 out of the dust collection box 711, so that the collected dust and impurities can be centrally processed.

[0038] Reference Figure 5 and Figure 9 A servo motor 41 is fixedly connected to the top side of the soaking tank 4. A threaded rod 42 is fixedly connected to the output end of the servo motor 41. A guide rod 43 is fixedly connected to the inner corner of the soaking tank 4. The threaded rod 42 is connected to the discharge component 44. The discharge component 44 includes a support seat 443 threadedly connected to the threaded rod 42. A connecting seat 442 is rotatably connected to one end of the support seat 443. A receiving mesh box 441 is fixedly connected to one side of the connecting seat 442. An electric push rod 444 is hinged between the connecting seat 442 and the support seat 443. Here, the two ends of the electric push rod 444 are hinged to the connecting seat 442 and the support seat 443, respectively.

[0039] The operation of the servo motor 41 drives the threaded rod 42 to rotate, which in turn drives the support base 443 to rise. This causes the support base 443 to move the receiving mesh box 441 upward, thereby separating the PCB board inside the receiving mesh box 441 from the developing solution. After separation, the operation of the electric push rod 444 can push the connecting seat 442 to rotate around the rotation point, which in turn causes the receiving mesh box 441 to rotate, thus pouring the PCB board inside the receiving mesh box 441 onto the conveyor 5. This process removes the PCB board without manual retrieval, making the operation convenient and safe, and improving the production efficiency of the PCB board.

[0040] Working principle: After starting the equipment, the PCB board to be exposed is placed on conveyor 1. The power of conveyor 1 drives the PCB board to be transported along the preset track until it is sent into the designated position inside the cleaning chamber 2. After the PCB board arrives at the cleaning chamber 2, the alignment component 6 starts to operate. Its internal components extend and push the PCB board laterally, gradually adjusting the PCB board to the middle reference position of the transport track to complete the adaptive alignment. After the alignment adjustment is completed, the clamping component inside the alignment component 6 is activated to stably clamp the PCB board to prevent deviation during subsequent transport. Then, the alignment component 6 drives the clamped PCB board to be transported towards the exposure chamber 3.

[0041] During the process of alignment component 6 driving the PCB board to exposure chamber 3, the internal linkage mechanism of alignment component 6 synchronously drives multiple cleaning components 8 to start operation. When the PCB board passes between the cleaning components 8, the internal components of the running cleaning components 8 synchronously clean the upper and lower surfaces of the PCB board to remove dust, impurities and other contaminants attached to the surface. At the same time as the cleaning components 8 are cleaning, the dust extraction component 7 is started simultaneously. Its internal power components operate and extract the air inside the cleaning chamber 2, sucking in and collecting the dust generated during cleaning in a timely manner, preventing dust and impurities from falling back onto the PCB board surface and ensuring the cleanliness of the PCB board.

[0042] After cleaning, the PCB board is transported into the exposure chamber 3. The two grippers 33 in the exposure chamber 3 move to clamp the two sides of the PCB board again to further ensure positioning accuracy. The electric push rod 32 starts to run and drives the grippers 33 to move along the preset direction through the extension and retraction action, thereby moving the clamped PCB board accurately to the working area of ​​the laser emitting unit 31. The laser emitting units 31 on the upper and lower sides start synchronously, emitting lasers to the upper and lower surfaces of the PCB board and performing uniform scanning exposure to complete the PCB board exposure production process.

[0043] After exposure, the electric push rod 32 moves the gripper 33 to transport the PCB board above the conveyor 9. Then, the gripper 33 releases, releasing the clamp on the PCB board, allowing it to fall onto the conveyor 9. The conveyor 9 starts running, transporting the PCB board into the immersion tank 4. Finally, the PCB board falls into the discharge component 44 inside the immersion tank 4. The PCB board is then immersed and developed by the developing solution inside the immersion tank 4. After development, the drive mechanism inside the immersion tank 4 operates, lifting the discharge component 44 upwards to completely separate the PCB board from the developing solution. The discharge component 44 then further moves, tilting the PCB board onto the conveyor 5. The conveyor 5 starts running, transporting the PCB board to the subsequent processing mechanism, completing the entire exposure-related process.
