Above the base 2, there is a fixed frame 3. Above the fixed frame 3, there is a cylinder 4. On the outer side wall of the fixed frame 3, a support frame 7, a fixed buckle 16 and a placing rack 25 are sequentially installed. Below the cylinder 4, a slide bar 5 is connected. The front end of the slide bar 5 is connected to a mounting plate 8. At the front end of the mounting plate 8, there is a fixed column 11. An insertion hole 12 is sleeved outside the fixed column 11 and a nut 15 is screwed outside the fixed column 11. Below the insertion hole 12, a chamfering knife 13 is connected. The front end of the support frame 7 is connected to a mounting frame 28. An electric push rod 29 is arranged inside the mounting frame 28. One end of the fixed buckle 16 is connected to an operating table 17. An installation groove 19 is opened inside the operating table 17. A bidirectional lead screw 20 is arranged inside the installation groove 19. A collar 22 is sleeved on the bidirectional lead screw 20 and one end of the bidirectional lead screw 20 is connected to a motor 21. The upper end of the collar 22 is connected to a limit plate 23. A collection box 26 is arranged inside the placing rack 25.

[0028] Preferably, a sliding groove 6 is formed in the fixing frame 3, and a sliding rod 5 is slidably installed in the sliding groove 6. By providing the sliding groove 6, the moving direction of the sliding rod 5 can be guided, facilitating the position movement of the sliding rod 5. The left and right ends of the mounting plate 8 are connected with guide rods 9, and guide grooves 10 are respectively formed in the left and right ends of the support frame 7. The guide rods 9 are slidably installed in the guide grooves 10. By providing the guide rods 9 and the guide grooves 10, the moving direction of the mounting plate 8 can be guided, preventing the mounting plate 8 from shifting in position during movement. Two groups of fixing columns 11 are symmetrically arranged, and washers 14 are sleeved on the fixing columns 11. The washers 14 are in close contact with the nuts 15. By providing the washers 14, the surface of the corner cutting knife 13 can be prevented from being worn during pre-tightening of the nuts 15.

[0029] Preferably, a cutting opening 18 is formed in the fixing buckle 16, and a collection box 26 is arranged below the cutting opening 18. By providing the cutting opening 18, the waste generated by cutting can be collected through the collection box 26. Two groups of limiting plates 23 are symmetrically arranged, and anti-slip pads 24 are fixedly installed on the inner walls of the limiting plates 23. By providing the anti-slip pads 24, the anti-slip property of the limiting plates 23 is increased, and the stability of the limiting plates 23 is improved. A handle 27 is installed on the outer side wall of the collection box 26, and the handle 27 is fixedly connected with the collection box 26. By providing the handle 27, it is convenient for the user to pick up and place the collection box 26. The lower part of the electric push rod 29 is connected with a pressing plate 30, and the pressing plate 30 is fixedly connected with the electric push rod 29. By providing the pressing plate 30, it is convenient for the user to press and limit the PCB board to be cut at the corners.

[0030] The working principle and process of the present utility model are as follows: When in use, place the PCB board to be chamfered on the operation table 17, control the operation of the motor 21, the motor 21 drives the bidirectional lead screw 20 to rotate. When the bidirectional lead screw 20 rotates, it drives the collar 22 to move on the bidirectional lead screw 20. When the two groups of collars 22 move, they drive the limit plate 23 and the anti-slip pad 24 to adjust the distance until the limit plate 23 moves to a suitable position. Then control the operation of the electric push rod 29, and the electric push rod 29 pushes the pressing plate 30 downward until the pressing plate 30 is in close contact with the surface of the lower PCB board. Control the cylinder 4 to push the sliding rod 5 downward, and the sliding rod 5 drives the mounting plate 8 to move downward in the support frame 7. When the mounting plate 8 moves downward, it drives the chamfering knife 13 connected thereto to move downward until the chamfering knife 13 chamfers the PCB board with the position limited, and the waste generated during the chamfering process enters the collection box 26 through the cutting opening 18 for collection. It can limit and fix PCB boards of different sizes according to the needs of users, ensuring the safety of the PCB board during chamfering and avoiding the situation of chamfering misalignment due to position shaking. When it is necessary to replace the chamfering knife 13, the user rotates the nut 15 by hand and rotates the nut 15 off the fixed column 11 in sequence. After removal, the washer 14 and the chamfering knife 13 are removed from the fixed column 11 in sequence, and a new knife can be re-fixed. It can disassemble and replace the chamfering knife 13 of the device according to production needs, increasing the practicality and convenience of the device and meeting the diverse needs of production. When it is necessary to process the waste after collection, the user pulls the handle 27 to pull out the collection box 26 from the placement rack 25. After the collection box 26 is taken out, the user pours the waste in the collection box 26 at the processing place and then places the collection box 26 back into the placement rack 25. It can centrally collect the waste generated by chamfering, reducing the subsequent work of the staff and avoiding the situation that the waste is inconvenient to clean and affects the subsequent work.
