All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0023] A PCB board corner processing device includes a bottom plate 1 and a top plate 5.

[0024] Above the two ends of the top of the bottom plate 1, there is a cutting component for cutting and processing the corners of the PCB board, and the cutting component is installed on the top plate 5. The cutting component includes a cylinder 6, a tool holder 7, a placement groove 8, and a cutting tool 9. The output end of the cylinder 6 passing through the bottom of the top plate 5 is fixedly connected to the tool holder 7. An placement groove 8 is opened at the bottom of the tool holder 7, and a cutting tool 9 for cutting the corners of the PCB is clamped inside the placement groove 8. Cutting grooves 3 are opened at the two ends of the top of the bottom plate 1, so that when the cutting tool 9 cuts the corners of the PCB board, it can fit against the inner wall of the cutting groove 3.

[0025] Fixed rods 4 are installed at the two ends of the bottom of the top plate 5. The bottom of the fixed rods 4 is fixedly installed on the bottom plate 1, and cylinders 6 are installed at the two ends of the top of the top plate 5. Clamping seats 13 are fitted and clamped on both sides of the cylinder 6, and the bottom of the clamping seats 13 is fixedly installed on the top of the top plate 5. By setting the clamping seats 13, it is convenient to fix and hold the cylinder 6, so as to improve the stability of the cylinder 6 during use.

[0026] In this utility model, by setting the above two sets of symmetric cutting components, it is convenient to process the two ends of the PCB board, so as to improve the efficiency of PCB board corner processing. Moreover, it is also convenient to disassemble, replace, and install the cutting tool 9 on the cutting component.

[0027] Furthermore, by starting the cylinder 6, its output end drives the cutting tool 9 provided at the bottom of the tool holder 7 to descend, so that the cutting tool 9 can cut the excess waste material at the corners of the PCB board. Then, it slides in along the inner wall of the cutting groove 3, so that the waste material cut from the PCB board can fall into the cutting groove 3, facilitating subsequent cleaning.

[0028] On the outer side of the bottom of the top plate 5, there is a shielding shell 12, and four sets of symmetric connecting blocks 11 are installed on the top of the shielding shell 12. The connecting blocks 11 are clamped in the corresponding connecting grooves 10 opened at the bottom of the top plate 5, and the connecting blocks 11 and the connecting grooves 10 are adapted to each other.

[0029] This utility model uses components such as a connection groove 10, a connection block 11, and a shielding shell 12 in cooperation, so as to facilitate shielding and protecting the cutting tool 9 on the cutting assembly, prevent waste chips from splashing out when cutting the corners of the PCB board, and cause harm to the operator.

[0030] Furthermore, by holding the shielding shell 12 by hand, the connection block 11 provided on its top is snapped into the corresponding connection groove 10 opened at the top and bottom, so as to fix the shielding shell 12 in a clamped manner, thereby facilitating the prevention of the cutting tool 9 from splashing out when cutting the waste material at the corners of the PCB board, and reducing the harm to the surrounding operators.

[0031] A placement table 2 for placing the PCB board is installed at the center of the top of the bottom plate 1. Limiting groove seats 16 are provided at both the front and back ends of the top of the bottom plate 1, and fixing blocks 15 are installed at the bottoms of the limiting groove seats 16. The fixing blocks 15 are snap-connected into the corresponding fixing grooves 14 opened at the top of the bottom plate 1. A micro electric telescopic rod 17 is installed at the top of the limiting groove seat 16, and the output end of the micro electric telescopic rod 17 passing through the limiting groove seat 16 is fixedly connected with a pressing rubber pad 18 for fixing the PCB board.

[0032] By using the above components such as the placement table 2, the fixing groove 14, the fixing block 15, the limiting groove seat 16, the micro electric telescopic rod 17, and the pressing rubber pad 18 in cooperation, it is convenient to press and fix the PCB board, so as to cut the waste material at its corners.

[0033] In addition, by holding the PCB board whose corners need to be cut by hand and placing it on the placement table 2, then, by starting the micro electric telescopic rod 17, its output end drives the pressing rubber pad 18 to descend, so as to press and fix the PCB board on the placement table 2 through it. At the same time, by providing the pressing rubber pad 18, it is also convenient to protect the PCB board when pressing and fixing it.

[0034] During specific use, by starting the air cylinder 6, its output end drives the cutting tool 9 provided at the bottom of the tool holder 7 to descend, so as to cut the redundant waste material at the corners of the PCB board by the cutting tool 9. Then, it slides in along the inner wall of the cutting groove 3, so as to facilitate the waste material cut from the PCB board to fall into the cutting groove 3, which is convenient for subsequent cleaning;

[0035] Furthermore, by holding the shielding shell 12 by hand, the connection block 11 provided on its top is snapped into the corresponding connection groove 10 opened at the top and bottom, so as to fix the shielding shell 12 in a clamped manner, thereby facilitating the prevention of the cutting tool 9 from splashing out when cutting the waste material at the corners of the PCB board, and reducing the harm to the surrounding operators.
