Description

Technical Field

[0001] The present invention relates to the field of circuit board manufacturing, and more particularly, to a turning mechanism for curing ink on a board material. Background Art

[0002] ‌A PCB substrate‌ is the basic material of a printed circuit board, which carries electronic components and realizes electrical connections between them.

[0003] The main materials of a PCB substrate include copper-clad laminates, prepregs, and copper foils, etc. Among them, the copper-clad laminate is the core material of the PCB substrate, which is composed of an insulating substrate and a copper foil. The insulating substrate can be paper-based, glass cloth-based, or composite material-based, etc., and the copper foil is used to form circuits.

[0004] UV light curing technology uses medium and short wave ultraviolet light to irradiate liquid UV materials. After the photoinitiator absorbs photons, free radicals or cations are formed, which initiate the polymerization and crosslinking of polymer materials containing active functional groups, and finally cure into a film. This technology has the advantages of instant curing, no volatile solvents, and environmental protection.

[0005] When a PCB substrate is subjected to ink curing operation, it needs to be turned over to cure its A and B sides respectively. When turning over, since the PCB substrate will change from a vertical state to a horizontal state, a certain lateral force will be obtained in the middle area of the PCB substrate during turning over, resulting in deformation of the PCB substrate during turning over, and then causing the ink layer to crack, affecting the ink curing effect and quality of the PCB board material.

[0006] Therefore, we make improvements in this regard and propose a turning mechanism for curing ink on a board material. Summary of the Invention

[0038] Example 3 further optimizes the turning mechanism for curing the plate ink provided in Example 1 or 2. Specifically, as Figure 1 、 Figures 8 - 10 shown, the conveying stability module 3 further includes two fixed frames 301, both of the two fixed frames 301 are fixedly connected to the conveying table frame 2. Two movable ports 302 are formed on one side outer wall of the two fixed frames 301. Movable bases 305 are movably connected to the inner walls of the four movable ports 302, and four stabilizing brackets 313 are respectively fixedly connected to one side outer wall of the four movable bases 305, and the four stabilizing brackets 313 are respectively located inside the two fixed frames 301.

[0039] Further, as Figure 9 and Figure 10As shown, two mounting rods 307 are provided on each of the four stabilizing brackets 313. The outer walls of the two mounting rods 307 on the same stabilizing bracket 313 are both provided with the same stabilizing arc member 306, and fixing rods 312 are fixedly connected to all four stabilizing brackets 313; when the PCB substrate fixture falls onto the conveying device, it can contact the stabilizing arc member 306.

[0040] Further, as Figure 9 and Figure 10 shown, two shaft rods 311 are movably connected to the outer walls of one side of the two fixing frames 301. One ends of the four shaft rods 311 are fixedly connected with eccentric plate members 309. Connecting rods 308 are provided on the four eccentric plate members 309. One ends of the four connecting rods 308 are movably connected to the fixing rods 312.

The outer walls of the two linkage wheels 310 on the same side are both provided with the same linkage belt 304. Servo motors 303 are fixedly connected to the outer walls of one side of the two fixing frames 301. The output shafts of the two servo motors 303 are fixedly connected to the outer walls of one side of two of the linkage wheels 310 respectively through couplings; the servo motor 303 can drive the shaft rod 311 to rotate, thereby driving the eccentric plate member 309 and the connecting rod 308 to operate, and further enabling the stabilizing bracket 313 to move up and down, so as to stably convey the PCB substrate fixture onto the conveying device.

[0041] After the device flips the PCB substrate fixture, it needs to convey it to the subsequent ink curing area. At this time, through the conveying and stabilizing module 3, the PCB substrate fixture can be stably moved from the flipping frame 12 to the conveying device, thereby avoiding situations such as the PCB substrate falling on the conveying device and being offset or tilted, so as to ensure the subsequent conveying operation of the PCB substrate fixture, and thus improve the use effect of the device.

[0042] The usage process of the flipping mechanism for sheet material ink curing processing provided by the present invention is as follows: During use, the PCB substrate fixture is conveyed to the substrate clamping frame 17, causing the elastic pad 16 to deform until the PCB substrate fixture is clamped inside the substrate clamping frame 17 for subsequent flipping. Before flipping, the general motor 828 runs. The general motor 828 drives the drive rod 804 and the winding wheel 805 to rotate, thereby winding the connecting line belt 826. As the connecting line belt 826 is tightened, it can pull the connecting piece 825 to move inside the moving guide port 823, and stretch the pull-back spring rod 824. At this time, as the connecting piece 825 moves, it can drive the mounting frame 801 to move, and make the mounting frame 801 move to the middle area of the PCB substrate. At this time, the air pump 813 is started. The air pump 813 transports gas through the delivery pipe 819 to the pressurized airbag 811 (during this process, the air flow sensor 814 can detect the gas flow rate and transmit the data to the inside of the controller 816, so as to control the opening and closing of the control valve 818 through the controller 816 to ensure that the gas flow rates in the two delivery pipes 819 are the same). As the pressurized airbag 811 expands, it can drive the anti-cracking splint 810 to move. At the same time, when performing this operation, the gas inside the pressurized airbag 811 can be transported to the inside of the telescopic airbag 808 through the connecting pipe 821, and make the telescopic airbag 808 drive the anti-cracking auxiliary plate 807 and the movable connecting plate 809 to move (to increase the clamping area and improve the anti-cracking effect) until the two anti-cracking splints 810 and the anti-cracking auxiliary plate 807 clamp the PCB substrate for subsequent flipping; When flipping, the flipping motor 5 is started. The flipping motor 5 drives the transmission wheel 19 and the linkage rod 4 to rotate, and cooperates with the drive belt 20 to make the two drive belts 20 run synchronously. Then, the drive belt 20 drives the movable block 18 to move up and down on the guide rod frame 21. At this time, as the movable block 18 runs, it can drive the second link member 13, and further drive the flipping frame 12, the first link member 11 and the flipping guide wheel 10 to move. Since the first link member 11 and the flipping guide wheel 10 will move along the guidance of the flipping guide groove 9, the flipping frame 12 can be flipped by 90 degrees, and thus the PCB substrate is changed from the vertical state to the horizontal state; After flipping, the flipping anti-cracking module 8 resets. The electric telescopic rod 14 drives the pushing plate 15 to run, so as to push out the PCB substrate fixture from the substrate clamping frame 17 and make it fall; During the falling operation, the servo motor 303 is started. The servo motor 303 drives the linkage wheel 310 to rotate, and cooperates with the linkage belt 304 to drive a plurality of shaft rods to rotate synchronously. Then, the eccentric plate member 309 drives the connecting rod 308 and the fixed rod 312 to run synchronously, so that the four stable brackets 313 and the movable base 305 rise along the guidance of the movable port 302. After rising to a certain position, the stable brackets 313 drive the stable arc member 306 to approach the PCB substrate fixture. At this time, the PCB substrate fixture falls, and the convex part of the fixture falls inside the stable arc member 306. Then, the servo motor 303 runs to drive the stable brackets 313 to descend, and make the PCB substrate fixture fall on the conveying device and be conveyed to the subsequent ink curing operation area.
