[0051] The projection of the auxiliary triangular plate 9 in the top view presents a right triangle.

[0052] Equipment preparation:

[0053] Ensure that the bottom support plate 1 is placed horizontally and stably, which is the basic support structure of the entire device. The core baffle 2 at the upper edge of the bottom support plate 1 is in a vertical state, and the core baffle 2 is in a right-angled fan shape when viewed from above, which plays a safety protection role such as limiting during the operation of the equipment.

[0054] Confirm that the core support block 3 is firmly welded to the upper side of the bottom support plate 1 near the corner, which is also the arc center. The core support block 3 provides support for subsequent components. The right-angled triangle plate 4 fixed on the core support block 3 has its right-angled side extending in a direction parallel to the extending direction of the edge of the bottom support plate 1.

[0055] Check that the core L-shaped plate 5 fixed on the two right-angled sides of the right-angled triangle plate 4, the core side support pad 7 on the inner side of the core L-shaped plate 5 and the core upper side support pad 6 on the upper side of the right-angled triangle plate 4 are not damaged and are firmly installed. These parts will be used to position one side of the circuit board.

[0056] Check the core telescopic rod 8 connected by the hinge shaft on both sides of the lower side of the right triangle plate 4. The main rod 81 of the core telescopic rod 8 rotates well with the lower side of the right triangle plate 4. The auxiliary triangle plate 9 connected to the ends of the telescopic parts 82 of the two core telescopic rods 8 can rotate flexibly, and the telescopic parts 82 are connected to the lower sides of the hypotenuse of the auxiliary triangle plate 9 through the hinge shaft.

[0057] Check the electric telescopic rod mechanism 10 connected to the middle of the lower side of the hypotenuse of the right-angled triangle plate body 4 through the hinge shaft, and check that the electric telescopic rod mechanism 10 and the middle of the lower side of the hypotenuse of the auxiliary triangle plate body 9 rotate properly. At the same time, confirm that the middle plate body 11 connected to the front side of the main rod body 81 of the two core telescopic rod bodies 8 by hinged connection, the hinged connection between the middle of the electric telescopic rod mechanism 10 and the middle of the middle plate body 11 is stable, and the electric telescopic rod mechanism 10 is parallel to the extension direction of the core telescopic rod body 8, and the hypotenuse of the right-angled triangle plate body 4 is parallel to the hypotenuse of the auxiliary triangle plate body 9, so as to ensure the coordination of the movement of the equipment.

[0058] Check that the auxiliary L-shaped plate 12 fixed on the two right-angled sides of the auxiliary triangular plate 9, the pressure sensor 14 fixed inside the auxiliary L-shaped plate 12 and the auxiliary side support pad 15 on the pressure sensor 14 are normal, and the auxiliary upper side support pad 13 on the upper side of the auxiliary triangular plate 9 is intact. At the same time, confirm that the support wheel 16 on the lower side of the auxiliary triangular plate 9 is in good contact with the upper side of the bottom support plate 1, and the support wheel 16 can ensure the smooth movement of the auxiliary triangular plate 9.

[0059] Check the support plate 17 fixed to the main rods 81 of the two core telescopic rods 8, the core gear 18 fixed to the rear end of the main rod 81 of any core telescopic rod 8, and the axis formed by the rotation between the core telescopic rod 8 and the bottom support plate 1 and the axis direction of the core gear 18. Confirm that the drive servo motor 19 fixed to the side of the core L-shaped plate 5 and the drive gear 20 on the output shaft of the drive servo motor 19 are in good meshing with the core gear 18.

[0060] Check that the side travel switches 21 symmetrically arranged on both sides of the support plate 17 and the rear travel switch 22 fixed at the rear side of the right angle of the auxiliary triangular plate 9 are normal. Finally, confirm that the electrical connection between the controller 23 fixed at the side of the core L-shaped plate 5 and the drive servo motor 19, the electric telescopic rod mechanism 10, the pressure sensor 14, the side travel switch 21, and the rear travel switch 22 is normal.

[0061] Place the circuit board:

[0062] Place the rectangular circuit board that needs to be punched on the support plate 17, and then adjust the position of the circuit board so that one of the corners of the circuit board is located on the core upper support pad 6 on the right-angled triangle plate 4, and the two side edges of the corner are tightly attached to the core side support pad 7 fixed on the inner side of the core L-shaped plate 5. At this time, one side of the circuit board has been preliminarily positioned.

[0063] Adjust the position of the auxiliary triangle plate:

[0064] The electric telescopic rod mechanism 10 is started by using the controller 23, and the controller 23 sends a control signal to the electric telescopic rod mechanism 10, and the electric telescopic rod mechanism 10 begins to extend and retract. As the electric telescopic rod mechanism 10 extends and retracts, the auxiliary triangular plate 9 is controlled to move toward the corresponding other corner of the rectangular circuit board. In this process, since the extension direction of the hypotenuse of the right-angled triangular plate 4 and the extension direction of the hypotenuse of the auxiliary triangular plate 9 are parallel to each other, it can be ensured that the auxiliary triangular plate 9 always maintains a suitable angle during the movement process, so as to perfectly fit the corresponding other corner of the rectangular circuit board.

[0065] At the same time, the controller 23 starts the driving servo motor 19, and the driving servo motor 19 rotates to drive the driving gear 20 on its output shaft to rotate. Due to the meshing between the driving gear 20 and the core gear 18, the core gear 18 rotates accordingly, thereby driving the core telescopic rod 8 to rotate, thereby adjusting the direction of the core telescopic rod 8. The rotation of the core telescopic rod 8 will further control the position of the auxiliary triangular plate 9 so that it can accurately align with the other corner of the circuit board.

[0066] Under the joint action of the electric telescopic rod mechanism 10 and the driving servo motor 19, the position of the auxiliary triangular plate 9 is continuously adjusted until the other corresponding corner of the rectangular circuit board is located on the auxiliary upper support pad 13 on the auxiliary triangular plate 9, and the two sides of the corner are closely attached to the auxiliary side support pad 15 fixedly provided on the inner side of the auxiliary L-shaped plate 12. At this time, the circuit board is stably fixed and accurately positioned through the right-angled triangular plate 4, the core L-shaped plate 5, the auxiliary triangular plate 9 and the auxiliary L-shaped plate 12, and the punching operation can be performed.

[0067] Security protection mechanism:

[0068] During the operation of the equipment, the pressure sensor 14 monitors the fixing pressure of the circuit board in real time to ensure that the circuit board is firmly fixed during the punching process. If insufficient pressure is detected, the controller 23 will automatically adjust the electric telescopic rod mechanism 10 and the drive servo motor 19 until the appropriate fixing pressure is reached. When the pressure sensor 14 receives an overload pressure, the pressure sensor 14 sends a signal to the controller 23. After receiving the signal, the controller 23 immediately controls the drive servo motor 19 and the electric telescopic rod mechanism 10 to stop rotating, thereby preventing the rectangular circuit board from being damaged by squeezing.

[0069] During the operation of the equipment, when the side travel switches 21 symmetrically arranged on both sides of the support plate 17 contact the core baffle 2, the side travel switches 21 will send a signal to the controller 23. After receiving the signal, the controller 23 will immediately control the drive servo motor 19 to stop rotating, thereby avoiding damage to the equipment due to excessive operation and ensuring the safety of the equipment.

[0070] When the rear travel switch 22 fixed on the rear side of the right-angled part of the auxiliary triangular plate 9 contacts the core baffle 2, the rear travel switch 22 will send a signal to the controller 23. After receiving the signal, the controller 23 controls the electric telescopic rod mechanism 10 to stop working, thereby preventing the equipment from malfunctioning due to abnormal movement and further ensuring the safety of the equipment.

The core upper support pad 6 and the auxiliary upper support pad 13 ensure that the corners of the circuit board are positioned accurately.

[0096] The core side support pads 7 and the auxiliary side support pads 15 on the core L-shaped plate 5 and the auxiliary L-shaped plate 12 respectively fix the two sides of the circuit board to ensure that the circuit board will not be displaced during the punching process.

[0097] Angle parallel design guarantee: The design that the extension directions of the hypotenuse of the right-angled triangle plate 4 and the hypotenuse of the auxiliary triangle plate 9 are parallel to each other makes it possible to always maintain a suitable angle when adjusting the position of the auxiliary triangle plate 9, ensuring the perfect fit between the auxiliary triangle plate 9 and the corners of the circuit board, further enhancing the positioning accuracy and reducing the punching error caused by positioning deviation.
