[0032] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-5 As shown, a device and method for resolving right-angled arcs in PCB pads or antennas are disclosed.

[0033] Example: A device for solving the problem of right-angle arcs in PCB pads or antennas includes a conveying frame 1, a cutting frame 2, a mounting frame 3, and two auxiliary frames 4. The cutting frame 2 is installed at the center of the upper end of the conveying frame 1, the mounting frame 3 is installed at the center of the lower end of the conveying frame 1, and the two auxiliary frames 4 are installed at the lower end of the conveying frame 1 and are located on both sides of the mounting frame 3. The upper end of the cutting frame 2 is provided with a cutting structure, the upper end of the mounting frame 3 and the auxiliary frames 4 are provided with a supporting and fixing structure, and the upper end of the conveying frame 1 is provided with an adjustment and limiting structure.

[0034] The cutting structure includes: two adjusting slots 5, two mounting plates 6, two adjusting motors 7, two adjusting lead screws 8, four guide rods 9, a moving plate 10, a first linear module 11, a third linear module 12, and a laser cutting machine 13;

[0035] Two adjustment slots 5 are respectively opened on the two side walls of the cutting frame 2. Two mounting plates 6 are respectively installed on the upper sides of the cutting frame 2. Two adjustment motors 7 are respectively installed on the upper ends of the two mounting plates 6. The bottom ends of the two adjustment screws 8 are respectively movably installed in the lower ends of the two mounting slots, and the upper ends of both screws 8 movably pass through the two mounting plates 6 and are connected to the drive ends of the two adjustment motors 7. Four guide rods 9 are respectively installed on the two sides of the two adjustment slots 5. The two ends of the moving plate 10 are respectively movably fitted onto the upper ends of the two adjustment screws 8 and the four guide rods 9. The first linear module 11 is installed on the lower end of the moving plate 10. The third linear module 12 is installed on the drive end of the first linear module 11. The laser cutting machine 13 is installed on the lower end of the third linear module 12.

[0036] It should be noted that when cutting the sheet material, the sheet material is conveyed by the set conveying frame 1. When it is conveyed to the designated position, the position of the sheet material is limited by the set adjustment limit structure. Then, the support and fixing structure is driven to support and fix the sheet material. Then, the adjustment motor 7 at the upper end of the drive mounting plate 6 is driven to work. The two adjustment motors 7 drive the two adjustment screws 8 to rotate, so that the moving plate 10 moves downward on the upper end of the two adjustment slots 5 and the four guide rods 9 until the laser cutting machine 13 is adjusted to the designated height. Then, the first linear module 11 and the laser cutting machine 13 are driven to work to laser cut the sheet material and make the right angle position of the sheet material protrude.

[0037] In the specific implementation process, the supporting and fixing structure includes: two supporting cylinders 14, a supporting frame 15, several supporting rods 16, several supporting plates 17, several suction cups 18, four limiting sleeves 19, four limiting rods 20, and an air pump 21.

[0038] Two support cylinders 14 are respectively installed on both sides of the lower end of the mounting frame 3.

The air pump 21 is installed on the lower end of the mounting frame 3 and the two auxiliary frames 4.

[0039] It should be noted that when supporting and fixing the board, the operator drives two support cylinders 14 to work, which pushes the support frame 15 upward. The support plate 17 at the upper end of the support rod 16 lifts the board. Then, the operator drives the air pump 21 to work. The air pump 21 cooperates with several suction cups 18 to adsorb the board onto the upper end of the support plate 17. The suction cups 18 adsorb and fix the board. The limiting sleeve 19 and the limiting rod 20 ensure the overall movement stability of the support frame 15.

[0040] In the specific implementation process, the adjustment limit structure includes: two second linear modules 22, two limit cylinders 23, and a limit frame 24;

[0041] Two second linear modules 22 are respectively installed on the outer walls of both sides of the conveying frame 1, and two limit cylinders 23 are respectively installed on the drive ends of the two second linear modules 22. The two ends of the limit frame 24 are respectively connected to the telescopic ends of the two limit cylinders 23.

[0042] It should be noted that when conveying the sheet material, the staff adjusts the two second linear modules 22 according to the specifications of the sheet material. Then, the limit cylinder 23 is driven to move the limit frame 24 downward. The lower end of the limit frame 24 limits the position of the conveyed sheet material.

[0043] In the specific implementation process, the third linear module 12 and the first linear module 11 are connected by bolts at their driving ends.

[0044] In the specific implementation process, the laser cutting machine 13 and the third linear module 12 are connected by bolts.

[0045] In the specific implementation process, a motor bracket 25 is provided at the connection between the adjusting motor 7 and the mounting plate 6.

[0046] In the specific implementation process, the third linear module 12 is U-shaped.

[0047] In the specific implementation process, the shape of the installation frame 3 is "U".

[0048] In the specific implementation process, the auxiliary frame 4 is U-shaped.

[0049] A method for solving the problem of right-angle arcs in PCB pads or antennas includes the following steps: S1, placing the board; S2, conveying the board; S3, limiting the conveying; S4, fixing the board; and S5, adjusting the cutting.

[0050] Step S1: Place the sheet material to be processed on the upper end of the conveyor frame 1;

[0051] Step S2: The sheet material is conveyed by multiple electric rollers within the conveying frame 1;

[0052] Step S3: Adjust and limit the conveying position of the plate by driving the adjustment limit structure;

[0053] Step S4: Support and fix the plate by driving the support and fixing structure;

[0054] Step S5: By driving the cutting structure to work, the plate is cut, and protruding cuts are made at right angle positions to reduce the asymmetric etching effect caused by etching.
