[0002] High frequency of electronic equipment is a development trend, especially with the increasing development of wireless networks and satellite communications, information products are moving towards high speed and high frequency, and communication products are moving towards large capacity and fast wireless transmission of voice, video and data standardization. Therefore, the development of a new generation of products requires high-frequency substrates, special circuit boards with higher electromagnetic frequencies, which are often used in automotive anti-collision systems, satellite systems, radio systems and other fields. The existing high-frequency boards need to be cut after gluing to cut off the excess parts.

[0003] For example, the patent document with announcement number CN212287765U discloses a cutting device for high-frequency and high-density circuit board production.

[0026] The bearing mechanism includes a bottom plate 301, which is connected to the top of the conveying device 102 by bolts, and a plurality of fixing columns 302 are connected to the top of the bottom plate 301 by bolts, and a storage plate 303 is connected to the top of the fixing columns 302 by bolts, and a cutting groove 304 is provided on the top of the storage plate 303, so that the circuit board can be placed on the top of the storage plate 303.

The output shaft of the motor 206 is connected to one end of the bidirectional lead screw 202 by a coupling. The motor 206 works to drive the bidirectional lead screw 202 to rotate, thereby driving the two threaded blocks 203 to approach each other, and then driving the two aligning plates 205 to approach each other, so as to align the circuit board.

[0027] The cutting mechanism includes two fixed plates 501, the fixed plates 501 are welded to the top of the base 1, the top of the fixed plates 501 is welded with a mounting plate 502, the bottom of the mounting plate 502 is connected to a cylinder 503 by bolts, the output shaft of the cylinder 503 is threadedly connected with a sliding plate 504, the sliding plate 504 is slidably connected to the inner side of the two fixed plates 501, the bottom of the sliding plate 504 is connected to a connecting column 505 by bolts, the bottom of the connecting column 505 is connected to a mounting frame 506 by bolts, the bottom of the mounting frame 506 is connected to a cutting knife 507 by bolts, the sliding plate 504 is driven to move downward by the operation of the cylinder 503, so that the mounting frame 506 is driven to move downward by the connecting column 505, and then the cutting knife 507 is driven to move downward, so as to cut the circuit board, and the pressing mechanism includes a mounting block 601, The mounting block 601 is connected to the bottom of the sliding plate 504 by bolts, and a mounting column 602 is welded at the bottom of the mounting block 601, and a second spring 603 is sleeved on the mounting column 602.

A pressing seat 605 is welded at the bottom of the moving plate 604. When the sliding plate 504 moves downward, the pressing mechanism can be driven to move downward. When the pressing mechanism moves downward, the pressing seat 605 will first contact the circuit board, and then the sliding plate 504 will continue to move downward, thereby driving the mounting block 601 to move downward, and then compressing the second spring 603. At the same time, the second spring 603 will generate a rebound force, which will be transmitted to the pressing seat 605 through the moving plate 604, so that the pressing seat 605 presses the circuit board tightly to avoid the circuit board from being offset during cutting.

[0028] The ejection mechanism includes a fixing frame 401, which is a U-shaped frame. The fixing frame 401 is welded to the bottom of the storage plate 303.

The top of the first spring 403 is provided with a pressing plate 404. The pressing plate 404 is slidably connected to the installation box 402. The top of the pressing plate 404 is welded with a cylindrical rod 405. The top of the cylindrical rod 405 is connected to a rectangular plate 406 by bolts. When the pressing seat 605 presses the circuit board downward, the pressing plate 404 is pressed downward. During the cutting process, the rectangular plate 406 will be pushed downward, thereby using the cylindrical rod 405 to drive the pressing plate 404 to move downward, thereby compressing the first spring 403. After the cutting is completed, the sliding plate 504 is driven upward by the cylinder 503, thereby driving the pressing mechanism to move upward until the pressing seat 605 is separated from the circuit board. At this time, under the action of the rebound force of the first spring 403, the pressing plate 404 will be pushed upward, thereby driving the rectangular plate 406 to move upward through the cylindrical rod 405, and then the cut circuit board will be ejected, thereby separating the waste from the cut circuit board.

[0029] Working principle: When in use, first place the circuit board to be cut on the top of the rectangular plate 406, and then the conveying device 102 works to drive the carrying mechanism to move, thereby driving the circuit board to move to the bottom of the alignment mechanism, and then the motor 206 works to drive the bidirectional lead screw 202 to rotate, thereby driving the two threaded blocks 203 to approach each other, and then driving the two alignment plates 205 to approach each other to align the circuit board. After the circuit board is aligned, the conveying device 102 works to drive the circuit board to move to the bottom of the cutting mechanism, and then the cylinder 503 works to drive the sliding plate 504 to move downward, thereby using the connecting column 505 to drive the mounting frame 506 to move downward, and then drive the cutting knife 507 to move downward to achieve cutting of the circuit board. During the downward movement of the sliding plate 504, the pressing mechanism can be driven downward. When the pressing mechanism moves downward, the pressing seat 605 will first contact the circuit board, and then The rear sliding plate 504 will continue to move downward, thereby driving the mounting block 601 downward, thereby compressing the second spring 603. At the same time, the second spring 603 will generate a rebound force, which will be transmitted to the pressing seat 605 through the moving plate 604, so that the pressing seat 605 presses the circuit board to prevent the circuit board from deviating during cutting. In the process of the pressing seat 605 squeezing the circuit board downward, the rectangular plate 406 will be pushed downward, thereby using the cylindrical rod 405 to drive the pressing plate 404 to move downward, thereby compressing the first spring 403. After the cutting is completed, the sliding plate 504 is driven upward by the cylinder 503, thereby driving the pressing mechanism to move upward until the pressing seat 605 is separated from the circuit board. At this time, under the action of the rebound force of the first spring 403, the pressing plate 404 will be pushed upward, thereby driving the rectangular plate 406 to move upward through the cylindrical rod 405, thereby ejecting the cut circuit board, thereby separating the waste from the cut circuit board.
