Description

Technical Field

[0001] The utility model relates to the technical field of PCB production equipment, in particular to an alignment LDI exposure device with an adjustable laser module. Background Art

[0002] In the process of producing PCB boards, image transfer between the exposure machine and the printed circuit board is a key link. To improve the exposure accuracy, it is necessary to use a laser to directly scan the required image data onto the working board surface by light to achieve parallel light source exposure. The existing traditional exposure machines are diffused light exposure machines and require a film negative, which affects the quality of the produced PCB boards. The existing LDI exposure machines have good alignment ability and strong resolution ability, but the equipment price is high and the structure is complex, increasing the manufacturing cost of PCB manufacturers.

[0003] Some existing LDI exposure machines that can perform double-sided exposure move the PCB board inside the exposure machine through a fixed alignment laser emitter for exposure. The laser emitter is fixed and cannot be adjusted according to the requirements of the PCB board, which easily causes economic losses due to unqualified products.

[0004] For example, the Chinese authorized patent with the publication number CN 208547810 U (an alignment LDI exposure machine with an adjustable laser module): includes a transmission device and a laser module; the laser module includes an upper laser module and a lower laser module; the upper laser module includes a driving device, an upper laser module mounting frame, a first laser module, and a roller connection component; the longitudinal frame is sequentially provided with a driving device, an upper laser module mounting frame, a roller connection component, a roller pressing component, a transverse frame, and a lower laser module from top to bottom; the upper laser module and the lower laser module are opposite to each other and can simultaneously expose the PCB board, improving the exposure speed; it can also synchronize the positions of double-sided exposure of the PCB board, without the position error caused by re-exposing the PCB board after turning it over, and the exposure distance can be adjusted by adjusting the upper laser module, which can effectively ensure the exposure accuracy of the LDI exposure machine and improve the product quality. This technical solution solves the above problems.

[0005] However, there are still some technical problems in the technical solution of this utility model. In order to meet the production requirements, the alignment LDI exposure machine with an adjustable laser module usually works at full load without rest throughout the day, resulting in inevitable failures after long-term use. The laser module of the alignment LDI exposure machine with an adjustable laser module is usually fixedly installed at the upper end of the alignment LDI exposure machine, so that when maintenance personnel repair the laser module, they need to repair the faulty part of the laser module in the narrow space inside the alignment LDI exposure machine, seriously affecting the repair efficiency of the PCB board.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Please refer to Figure 1-6 , an embodiment provided by the present utility model: an alignment LDI exposure device with an adjustable laser module, including an alignment LDI exposure internal support 1:

[0030] The limit fixing rod 15 is fixedly installed on the rear end face of the inner bracket 1 of the alignment LDI exposure. A mating connection bracket 14 is installed outside the limit fixing rod 15 through a card slot. An upper top spring 18 is fixedly installed inside the limit fixing rod 15. A clamping member 19 is fixedly installed at the upper end of the upper top spring 18. A limit guide rail 17 is fixedly installed on the rear end face of the mating connection bracket 14. Installing the limit fixing rod 15 can enable the mating connection bracket 14 to be stably installed at the upper end of the device, prevent the mating connection bracket 14 from shaking, and play a supporting role for the mating connection bracket 14. At the same time, the limit fixing rod 15, in cooperation with the upper top spring 18 and the clamping member 19, can quickly fix the mating connection bracket 14, making it more convenient for the staff to repair this device. A disassembly pressing plate 16 is installed outside the limit guide rail 17 through a card slot. A magnetic block 20 is arranged above the clamping member 19. Installing the magnetic block 20 and the disassembly pressing plate 16 enables the staff, when they need to disassemble this device, to only push the disassembly pressing plate 16 to press the magnetic block 20 into the limit fixing rod 15, causing the clamping member 19 to retract into the limit fixing rod 15, thus releasing the limit of the clamping member 19 on the mating connection bracket 14, making the device more convenient to repair. When the device fails, the staff can quickly remove this device for targeted repair, avoiding the staff from repairing in the narrow space inside the alignment LDI exposure machine, which is beneficial to reducing the repair difficulty of the staff, improving the repair efficiency of the staff, and ensuring that production can be quickly restored. The magnetic block 20 is magnetically connected to the disassembly pressing plate 16;

[0031] The assembly plates 8 are arranged at the upper and lower ends of the mating connection bracket 14. There are two assembly plates 8. The assembly plate 8 above the inner bracket 1 of the alignment LDI exposure is rotatably connected to the mating connection bracket 14 through a connecting shaft. The assembly plate 8 below the inner bracket 1 of the alignment LDI exposure is fixedly connected to the mating connection bracket 14. Installing two assembly plates 8 and enabling one of the assembly plates 8 to be folded can directly expose the laser module main body 12 installed inside the assembly plate 8, facilitating the staff to quickly repair this device, making the device more user-friendly, and greatly reducing the repair difficulty of the device. Limit shafts 10 are slidably installed inside both of the two assembly plates 8 through card slots. A longitudinal adjustment plate 9 is fixedly installed at one end of the limit shaft 10 away from the inner bracket 1 of the alignment LDI exposure. A height adjustment lead screw 11 is installed inside the longitudinal adjustment plate 9 through a ball screw nut pair. Installing the height adjustment lead screw 11 can adjust the position of the longitudinal adjustment plate 9, and further enable the longitudinal adjustment plate 9 to adjust the positions of the laser module mounting plate 21 and the laser module main body 12 through the limit shaft 10, making the device more flexible. One end of the height adjustment lead screw 11 is rotatably connected to the assembly plate 8 through a bearing. A laser module mounting plate 21 is fixedly installed at one end of the limit shaft 10 close to the inner bracket 1 of the alignment LDI exposure. The laser module main body 12 is fixedly installed outside the laser module mounting plate 21.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , on one side inside the alignment LDI exposure inner bracket 1, a first conveying roller 2 is rotatably installed through a bearing, on the other side inside the alignment LDI exposure inner bracket 1, a second conveying roller 4 is rotatably installed through a bearing, and a middle driving roller 22 is rotatably installed inside the alignment LDI exposure inner bracket 1 through a bearing. Side conveying belts 3 are arranged on both sides between the middle driving roller 22 and the first conveying roller 2. Installing the side conveying belts 3 and the middle conveying belt 5 can transport the PCB board, ensuring that the laser module main body 12 can uniformly irradiate the PCB board and enhancing the use effect of the device. A middle conveying belt 5 is arranged between the middle driving roller 22 and the second conveying roller 4. On both sides of the front end of the upper front surface of the alignment LDI exposure inner bracket 1, fixed bosses 6 are fixedly installed. The fixed bosses 6 are slidably connected to the assembly plate 8 through a card slot. Connecting rods 13 are arranged inside both sides of the alignment LDI exposure inner bracket 1, and the connecting rods 13 are fixedly connected to the alignment LDI exposure inner bracket 1. A driving motor 7 is fixedly installed on the front end surface of the alignment LDI exposure inner bracket 1. The driving motor 7 is connected to the middle driving roller 22 through a coupling. The clamping member 19 is slidably connected to the limit fixing rod 15 through a card slot. A trapezoidal support plate is installed at the upper end inside the cooperating connection bracket 14, and the trapezoidal support plate is fixedly connected to the cooperating connection bracket 14.

[0033] Working principle: When in use, the staff installs this device inside the alignment LDI exposure machine. Then, the staff places the PCB board on the upper end of the side conveying belt 3. Next, the driving motor 7 drives the middle driving roller 22 to rotate, causing the side conveying belt 3 and the middle conveying belt 5 to rotate synchronously. As a result, the PCB board can move stably inside the device. During the movement of the PCB board, the laser module main body 12 performs exposure operations on the PCB. When a fault occurs in the laser module main body 12, the staff pushes the disassembly pressing plate 16, causing the disassembly pressing plate 16 to squeeze the magnetic block 20 into the limit fixing rod 15, and the clamping member 19 retracts into the limit fixing rod 15. Then, the staff can pull out the mating connection bracket 14 and the assembly plate 8. Next, the staff flips the upper assembly plate 8, and the laser module main body 12 can be directly exposed, facilitating the staff to quickly repair the damaged laser module main body 12. The installation of the limit fixing rod 15 in this device enables the mating connection bracket 14 to be stably installed at the upper end of the device, preventing the mating connection bracket 14 from shaking and playing a supporting role for the mating connection bracket 14. At the same time, the limit fixing rod 15, in cooperation with the upper top spring 18 and the clamping member 19, can quickly fix the mating connection bracket 14, making it more convenient for the staff to repair this device. The installation of the magnetic block 20 and the disassembly pressing plate 16 allows the staff, when they need to disassemble this device, to simply push the disassembly pressing plate 16 to press the magnetic block 20 into the limit fixing rod 15, causing the clamping member 19 to retract into the limit fixing rod 15, thereby releasing the limit of the clamping member 19 on the mating connection bracket 14, making the device more convenient to repair. When a fault occurs in the device, the staff can quickly remove this device for targeted repair, avoiding the staff from repairing in the narrow space inside the alignment LDI exposure machine, which is beneficial to reducing the repair difficulty of the staff, improving the repair efficiency of the staff, ensuring that production can resume quickly. The installation of two assembly plates 8 and enabling one of the assembly plates 8 to be folded can directly expose the laser module main body 12 installed inside the assembly plate 8, facilitating the staff to quickly repair this device, making the device more user-friendly, and greatly reducing the repair difficulty of the device.
