[0004] However, the above solution cannot correct the position of the circuit board, thus preventing deviation during loading. Furthermore, the number of transport rollers is fixed, making it inconvenient to add or remove them according to requirements. Utility Model Content

[0019] A preferred embodiment of the feeding and anti-deviation conveying mechanism for flexible circuit board atmospheric plasma machines provided by this utility model is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: A feeding and anti-deviation conveying mechanism for a flexible circuit board atmospheric plasma machine includes a conical correction roller 1; a limiting roller 2 with V-shaped grooves distributed on the side of the correction roller 1; and several sets of alignment rollers 3 distributed on the side of the limiting roller 2 away from the correction roller 1. The correction roller 1 can initially correct the position of the circuit board, while the limiting roller 2 can perform secondary correction. Finally, the circuit board is output through the alignment rollers 3, completing the anti-deviation alignment feeding of the circuit board; a hollow roller 301 distributed in the middle of the alignment rollers 3; and air guide holes 302 provided on the alignment rollers 3. The hollow roller 301 and the air guide holes 302 can generate suction force on the alignment rollers 3, so that the circuit board can be adsorbed on the side of the alignment rollers 3, facilitating the positioning and correction of the circuit board; and a support frame 4 distributed below the correction roller 1, the limiting roller 2, and the alignment roller 3, which can facilitate the combination and connection between the correction roller 1, the limiting roller 2, and the alignment roller 3.
[0020] It should be noted that the existing system cannot correct the position of the circuit board, thus preventing it from shifting during loading. Furthermore, the number of transport rollers is fixed, making it inconvenient to add or remove them as needed.
[0021] In this embodiment, the conical correction roller 1 can initially correct the position of the circuit board when it comes into contact with the inclined surface. Then, in conjunction with the next set of limiting rollers 2 with V-grooves, the circuit board can be corrected to the V-groove of the limiting roller 2, thus completing the position adjustment of the circuit board. Finally, the alignment roller 3 with adsorption effect moves to complete the feeding.
[0022] In a further preferred embodiment of the present invention, a first transmission rod 101 is fixed in the middle of the correction roller 1, and a second transmission rod 201 is provided in the middle of the limiting roller 2.
[0023] In this embodiment, this facilitates the rotation of the correction roller 1 and the limiting roller 2.
[0024] In a further preferred embodiment of the present invention, a first transmission gear 5 is fixed to the outer side of one end of the first transmission rod 101, the second transmission rod 201, and the hollow roller 301.
[0025] In this embodiment, the first transmission gear 5 can conveniently and synchronously drive the first transmission rod 101, the second transmission rod 201, and the hollow roller 301 to rotate, so that the rotation direction and speed of the correction roller 1, the limiting roller 2, and the alignment roller 3 are consistent.
[0026] In a further preferred embodiment of the present invention, one end of the hollow roller 301 is connected to a connector 303, a connecting pipe 304 is connected to the connector 303, and a vacuum machine 305 is connected to the end of the connecting pipe 304 away from the hollow roller 301.
[0027] In this embodiment, the vacuum machine 305 maintains negative pressure inside the hollow roller 301, so that the alignment roller 3 can adsorb and position the circuit board.
[0028] In a further preferred embodiment of this utility model, support plates 401 are vertically fixed at the top of both ends of the support frame 4. The support plates 401 are rotatably connected to the first transmission rod 101, the second transmission rod 201 and the hollow roller 301. The first transmission gear 5 is located on the outside of the support plate 401. Limiting blocks 402 are fixed at both ends of the support plate 401 near the first transmission gear 5. The cross-section of the limiting blocks 402 is set as an "L" shape, and two sets of limiting blocks 402 are mirror-fixed on a single set of support plates 401.
[0029] In this embodiment, two sets of limiting blocks 402 can facilitate the connection between adjacent support frames 4 via the first connecting plate 7 and the second connecting plate 8, and the first transmission gear 5 placed on the outside can easily drive each other.
[0030] In a further preferred embodiment of the present invention, a motor 6 is installed on one side of the support plate 401, and a third transmission rod 601 is connected to one end of the motor 6 near the support frame 4. The end of the third transmission rod 601 away from the motor 6 is connected to the first transmission rod 101 of the correction roller 1.
[0031] In this embodiment, the motor 6 can drive the first transmission rod 101 to rotate via the third transmission rod 601.
[0032] In a further preferred embodiment of the present invention, a first connecting plate 7 is slidably connected to the side of the support plate 401 near the motor 6. The side of the first connecting plate 7 has an "L" shaped structure, and a first connecting bolt 701 is threadedly connected to the lower end of the first connecting plate 7 at the connection point with the support frame 4. A threaded hole 403 is provided at the connection point between the support frame 4 and the first connecting bolt 701. A second transmission gear 702 is rotatably provided on the side of the first connecting plate 7 away from the support frame 4. The second transmission gear 702 meshes with the first transmission gear 5.
[0033] In this embodiment, the first connecting plate 7 can be combined and connected with the support plate 401 and fixed by the first connecting bolt 701 at the bottom. Then, the second transmission gear 702 on the side of the first connecting plate 7 can transmit power between the two adjacent sets of first transmission gears 5, and keep the rotation direction and speed of the two adjacent sets of first transmission gears 5 consistent.
[0034] In a further preferred embodiment of the present invention, a second connecting plate 8 is slidably connected to the side of the support plate 401 away from the first connecting plate 7, and the second connecting plate 8 is also slidably connected to the limiting block 402. A second connecting bolt 801 is threadedly connected to the lower end of the second connecting plate 8 at the connection point with the support frame 4, and a threaded hole 403 is also provided at the connection point between the support frame 4 and the second connecting bolt 801.
[0035] In this embodiment, the second connecting plate 8 is connected to the support plate 401, and in conjunction with the second connecting bolt 801 at the bottom and the support frame 4, the two adjacent support frames 4 can be fixed together.
[0036] In summary, the inclined surface of the tapered correction roller 1 allows the circuit board to be initially corrected upon contact, positioning it into the V-groove of the limiting roller 2, thus completing the adjustment of the circuit board's position. Finally, through the air guide hole 302 provided on the limiting roller 3, when the vacuum machine 305 is working, the hollow roller 301 and the air guide hole 302 are connected through the connecting pipe 304 and the connector 303, generating suction on the side of the alignment roller 3. This allows the circuit board to be adsorbed onto the side of the alignment roller 3, facilitating the positioning and correction of the circuit board. The correction roller 1, the limiting roller 2, and the alignment roller 3 can be combined and connected by the support frame 4 provided thereon. After the first connecting plate 7 and the second connecting plate 8 are slidably connected to the limiting blocks 402 of the two adjacent sets of support frames 4, the first connecting bolt 701 and the second connecting bolt 801 are used for threaded connection and fixation. In this way, the combination and fixation between the correction roller 1, the limiting roller 2, and the alignment roller 3 can be completed. When the motor 6 is working, it drives the first transmission rod 101 to rotate, and the first transmission gear 5 on the outer side of the first transmission rod 101 will rotate. At this time, since the first connecting plate 7 at the connection point is provided with second transmission gears 702, the second transmission gears 702 can drive the other second transmission rods 201 and the first transmission gears 5 on the hollow roller 301 to rotate, so that the correction roller 1, the limit roller 2 and the alignment roller 3 can rotate synchronously after being combined, which facilitates the combination and arrangement adjustment of the device.
