Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0021] Reference Figure 1-Figure 3 A circuit board soft board motherboard cutting device comprises a base 1, guide rails 2 are fixedly installed on both sides of the base 1, a mounting frame 3 is slidably installed on the guide rails 2, a pressing rod 4 is slidably sleeved on the mounting frame 3, a pressing plate 5 is fixedly installed on one end of the pressing rod 4 close to the base 1, sliding grooves are opened on both sides of the mounting frame 3, two groove walls of the sliding groove are respectively slidably connected to the two ends of the pressing plate 5, and a cutting knife 6 is fixedly installed on one side of the pressing plate 5 close to the base 1;

[0022] A reset spring 13 is fixedly mounted on one side of the mounting frame 3 close to the base 1. One end of the reset spring 13 close to the base 1 is fixedly connected to the pressing plate 5. The reset spring 13 is slidably sleeved with the pressing rod 4. A fixing device is provided on the base 1 for fixing the circuit board.

[0023] When it is necessary to cut the circuit board, the mounting frame 3 can be moved according to the required cutting length, and the pressing plate 5 can be driven to move by the mounting frame 3, and the cutting knife 6 can be driven to move to the specified position by the pressing plate 5, and the pressing rod 4 can be pressed to make the pressing rod 4 drive the pressing plate 5 to move downward, and the cutting knife 6 can be moved to the surface of the circuit board by the movement of the pressing plate 5, and the circuit board can be cut. When the cutting is completed, the pressing plate 5 is driven to move upward by the elastic force of the reset spring 13, so that the cutting knife 6 is reset to avoid affecting the subsequent cutting work. The position of the cutting knife 6 can be effectively changed according to the cutting needs, thereby improving applicability, reducing the difficulty of operation, and avoiding the breakage of the circuit board due to uneven pressure.

[0024] The fixing device includes a fixing frame 7 fixedly mounted on one side of the base 1 and a sliding frame 8 slidably mounted on the surface of the base 1. The sliding frame 8 is the same size as the fixing frame 7. Sliding blocks 9 are fixedly mounted on both ends of the sliding frame 8. The sliding blocks 9 are slidably connected to the guide rails 2. Locking devices are provided on the fixing frame 7 and the sliding frame 8. When it is necessary to cut the circuit board, the position of the sliding frame 8 can be adjusted according to the size of the circuit board. By pushing the sliding block 9, the sliding frame 8 is driven to approach the fixing frame 7 through the movement of the sliding block 9, and the circuit board is placed between the fixing frame 7 and the sliding frame 8. By shortening the distance between the sliding frame 8 and the fixing frame 7, the circuit board is fixed to avoid the circuit board sliding during the cutting process, resulting in a decrease in accuracy.

[0025] The locking device includes two fixing plates 10 respectively slidably installed in the sliding frame 8 and the fixing frame 7, and two pull rods 11 respectively slidably sleeved on the sliding frame 8 and the fixing frame 7. The end of the pull rod 11 close to the base 1 is fixedly connected to the fixing plate 10. A plurality of fixing springs 12 are fixedly installed in both the sliding frame 8 and the fixing frame 7. The end of the fixing spring 12 close to the base 1 is fixedly connected to the fixing plate 10. The fixing spring 12 is slidably sleeved with the pull rod 11. When the circuit board is placed between the fixing frame 7 and the sliding frame 8, the fixing plate 10 is pressed down by the elastic force of the fixing spring 12, and the circuit board is locked by the fixing plate 10 to prevent the circuit board from sliding. When the cutting is completed, the pull rod 11 is pulled to drive the fixing plate 10 to move up, thereby releasing the lock on the circuit board.

[0026] A plurality of scale lines 16 are fixedly mounted on the surface of the base 1, and the distances between the plurality of scale lines 16 are equal. The scale lines 16 are used to control the distance between the fixed frame 7 and the sliding frame 8, so that the staff can adjust the distance conveniently and improve the efficiency of positioning the circuit board.

[0027] A limit block 14 is slidably mounted on the guide rail 2, a plurality of threaded holes are provided on the surface of the base 1, a limit nut 15 is threadedly inserted on the limit block 14, and the limit nut 15 is engaged with the threaded hole. When the length to be cut is confirmed, the limit block 14 can be moved to the cutting position by sliding the limit block 14, and the limit nut 15 can be tightened to engage the limit nut 15 with the corresponding threaded hole, and then the cutting knife 6 can be moved to the side of the limit block 14, and the position of the cutting knife 6 can be fixed by the limit block 14 to prevent the sliding of the cutting knife 6 during the cutting process, resulting in a decrease in cutting accuracy.

[0028] The lower surface of the base 1 is fixedly connected with an anti-skid layer made of rubber, which can effectively prevent the equipment from sliding during the cutting process of the circuit board, resulting in a decrease in cutting accuracy, thereby improving the cutting accuracy.

[0029] In the utility model, when it is necessary to cut the circuit board, the mounting frame 3 can be moved according to the required cutting length, and the pressing plate 5 can be driven to move by the mounting frame 3, and the cutting knife 6 can be driven to move to the specified position by the pressing plate 5, and the pressing rod 4 can be pressed to make the pressing rod 4 drive the pressing plate 5 to move downward, and the cutting knife 6 can be moved to the surface of the circuit board through the movement of the pressing plate 5, and the circuit board can be cut. When the cutting is completed, the pressing plate 5 is driven to move upward by the elastic force of the reset spring 13, so that the cutting knife 6 is reset to avoid affecting the subsequent cutting work. The position of the cutting knife 6 can be effectively changed according to the cutting needs, thereby improving applicability, reducing the difficulty of operation, and avoiding the breakage of the circuit board due to uneven pressure.

[0030] In general, in view of the technical problems: when the existing circuit boards are cut, most of the cutting knives 6 are fixed on the equipment. Because the sizes of the circuit boards to be cut are different, the jigs need to be replaced frequently, which has poor applicability and troublesome operation. In addition, the uneven pressure during cutting can easily leave marks or even break the circuit boards, which is not conducive to the smooth progress of the cutting work. The technical solution is adopted: through the cooperation of the cutting knife 6, the pressing plate 5, the reset spring 13, the pressing rod 4, the mounting frame 3 and the guide rail 2, the position of the cutting knife 6 can be effectively changed according to the cutting needs, the applicability is improved, the difficulty of operation is reduced, and at the same time, the pressure caused by the pressure can be avoided. Uneven force causes the circuit board to break; because the implementation process of the technical solution is: when the circuit board needs to be cut, the mounting frame 3 can be moved according to the length of the cutting to be required, and the pressing plate 5 can be driven to move by the mounting frame 3, and the cutting knife 6 can be driven to move to the specified position by the pressing plate 5, and the pressing rod 4 is pressed to make the pressing rod 4 drive the pressing plate 5 to move downward, and the cutting knife 6 is moved to the surface of the circuit board through the movement of the pressing plate 5, and the circuit board is cut. When the cutting is completed, the elastic force of the reset spring 13 drives the pressing plate 5 to move upward, so that the cutting knife 6 is reset to avoid affecting the subsequent cutting work. Therefore, this technical problem can be solved, and the technical effect achieved is: the position of the cutting knife 6 can be effectively changed according to the cutting needs, the applicability is improved, the difficulty of operation is reduced, and at the same time, the circuit board can be prevented from breaking due to uneven pressure.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
