Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a cutting device for PCB board production. Background Technology

[0002] According to the patent document with publication number CN218243988U, the circuit board is fixed by a lifting motor driving the fixing plate to move downward along the lifting guide rail. After the fixing is completed, the linear motor and the drive motor are started. The linear motor drives the feeding baffle to move downward along the linear guide rail towards the cutting blade. At this time, the drive motor drives the lifting threaded rod to rotate, which in turn drives the lifting moving table and the mounting plate on it to move downward. After moving to a suitable height, it stops. Then the cutting cylinder pushes the cutting blade to move towards the circuit board and cuts it.

[0003] During the cutting process described in the patent document, due to the relatively hard material of the circuit board, some cracks may occur on the end face of the circuit board when cutting by pressing downwards. In addition, when cutting some circuit boards with soldered control components, the above cutting method may cause slight lifting near the cutting position due to local stress on the circuit board, and in this process, the soldered control components may become detached.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, a PCB board production cutting equipment includes a frame 5, a feeding component on one side of the frame 5, a board feeding mechanism 1 on the other side of the frame 5, support rods 6 fixed on both the front and rear sides of the frame 5, and a cutting mechanism 2 and a clamping mechanism 3. The cutting mechanism 2 is located at the upper end of the two support rods 6, and the clamping mechanism 3 is located between the board feeding mechanism 1 and the feeding component.

[0030] In this embodiment: the cutting mechanism 2 includes a fixed frame 21, a cutting moving frame 24 is slidably connected to one side of the fixed frame 21, a cutting motor 25 is fixed to one side of the cutting moving frame 24, a cutting blade 26 is fixed to the rotating part of the cutting motor 25, a drive screw 23 is rotatably connected inside the fixed frame 21, a drive motor 22 is fixedly installed at the input end of the drive screw 23, the cutting blade 26 is located inside the cutting moving frame 24, the drive screw 23 is threadedly connected to the cutting moving frame 24, a dust removal mechanism 4 is provided on one side of the two cutting blades 26, the rotating part of the cutting motor 25 drives the cutting blade 26 to rotate inside the cutting moving frame 24, and at the same time the drive motor 22 drives the drive screw 23 to rotate, the rotation of the drive screw 23 drives the cutting moving frame 24 to move back and forth on one side of the fixed frame 21, and the movement of the fixed frame 21 drives the cutting blade 26 to cut the PCB board.

[0031] In this embodiment: the clamping mechanism 3 includes two vertically symmetrical clamping frames 34. Each clamping frame 34 has a connecting seat 32 at both its front and rear ends. Each connecting seat 32 has a connecting rod 33 hinged at both its upper and lower ends. The end of the connecting rod 33 away from the connecting seat 32 is hinged to the clamping frame 34. A clamping cylinder 31 is fixedly installed at the end of the two connecting seats 32 that are close to each other. A buffer sponge is provided at the end of the two clamping frames 34 that are close to each other. The fixed part of the two clamping cylinders 31 is fixedly connected to the front and rear sides of the frame 5. The telescopic parts of the two clamping cylinders 31 extend simultaneously to drive the two connecting seats 32 away from each other. During this process, the two connecting rods 33 on each connecting seat 32 close together, thereby driving the two clamping frames 34 to move closer together to clamp and fix the next cut PCB board. During clamping, the buffer sponge on the clamping frame 34 abuts against the upper and lower sides of the PCB board to avoid damage to the PCB board.

[0032] In this embodiment: the dust removal mechanism 4 includes a dust suction hood 41. The front and rear ends of the dust suction hood 41 are fixed to the top of one side of the frame 5. The rear end of the dust suction hood 41 is connected to a dust suction pipe 42. The other end of the dust suction pipe 42 is fixedly provided with a filter cover 43. The lower side of the filter cover 43 is provided with a fan 44 for drawing air into it. The filter cover 43 is provided with a filter screen for filtering cutting dust. The fan 44 draws out the air in the filter cover 43 and forms a suction force at the dust suction hood 41 through the dust suction pipe 42. Thus, the dust generated during cutting is adsorbed by the dust suction hood 41. The dust will enter the filter cover 43 through the dust suction hood 41 and the dust suction pipe 42, and be filtered by the filter screen in the filter cover 43.

[0033] In this embodiment: the feeding assembly includes two feeding rollers 9, both ends of which are rotatably connected to one side of the frame 5. The two feeding rollers 9 are fitted with feeding belts 8 on their outer sides. A feeding motor 7 is fixedly installed at the input end of the feeding rollers 9. A sliding plate is provided between the dust hood 41 and the feeding belt 8. The sliding plate is located at the end of the feeding belt 8 near the support rod 6. The feeding rollers 9 are rotated by the rotating part of the feeding motor 7. The rotation of the feeding rollers 9 drives the feeding belt 8 to feed out the cut PCB board.

[0034] In this embodiment: the board feeding mechanism 1 includes a board feeding frame 11, with board feeding rollers 12 rotatably connected to both ends of the board feeding frame 11. Each board feeding roller 12 is provided with two symmetrical board feeding belts 14. Each board feeding belt 14 has two rollers on its inner side. The two rollers inside the board feeding belt 14 are respectively fixed on the two board feeding rollers 12. A board feeding motor 13 for driving the board feeding rollers 12 to rotate is fixed on the rear side of the frame 5. The board feeding frame 11 is fixedly connected to the frame 5. The rotating part of the board feeding motor 13 drives the board feeding rollers 12 to rotate. The two rollers on the board feeding rollers 12 drive the two board feeding belts 14 to rotate synchronously. Then, the two board feeding belts 14 are used to drive the PCB board to move towards the cutting position.

[0035] Working principle: When in use, the PCB board to be cut is placed on the two feeding belts 14. Then, the feeding motor 13 drives the feeding roller 12 to rotate. The two rollers on the feeding roller 12 drive the two feeding belts 14 to rotate synchronously. Then, the two feeding belts 14 drive the PCB board to move towards the cutting position.

[0036] When the PCB board moves between the two clamping frames 34, the board feeding motor 13 stops rotating. At the same time, the telescopic parts of the two clamping cylinders 31 extend to drive the two connecting seats 32 away from each other. During this process, the two connecting rods 33 on each connecting seat 32 close together, thereby driving the two clamping frames 34 to move closer together to clamp and fix the next PCB board to be cut. The PCB board to be cut is located on one side of the cutting blade 26. During clamping, the buffer sponge on the clamping frame 34 is used to press against the upper and lower sides of the PCB board to avoid damage to the PCB board.

[0037] After the PCB board is clamped and fixed, the cutting motor 25 drives the cutting blade 26 to rotate inside the cutting moving frame 24. At the same time, the drive motor 22 drives the drive screw 23 to rotate. The rotation of the drive screw 23 drives the cutting moving frame 24 to move back and forth on one side of the fixed frame 21. The movement of the fixed frame 21 drives the cutting blade 26 to cut the PCB board. The cut PCB board will fall onto the delivery belt 8 along the slide. Then, the delivery motor 7 drives the delivery roller 9 to rotate. The rotation of the delivery roller 9 drives the delivery belt 8 to send out the cut PCB board.

[0038] Subsequently, the telescopic parts of the two clamping cylinders 31 retract simultaneously, causing the two connecting seats 32 to move towards the front and rear sides of the frame 5. The movement of the two connecting seats 32 causes the corresponding two connecting rods 33 to open up to each other, thereby causing the two clamping frames 34 to move away from each other, so that the clamping frames 34 can be released from the next PCB board to be cut. Then, the board feeding mechanism 1 moves the next PCB board to one side of the cutting blade 26.

[0039] Subsequently, during the cutting process, the fan 44 is used to extract the air from the filter cover 43, and the suction pipe 42 forms a suction force at the suction cover 41, thereby adsorbing the dust generated during the cutting process through the suction cover 41. The dust will enter the filter cover 43 through the suction cover 41 and the suction pipe 42, and be filtered by the filter screen inside the filter cover 43, thereby reducing the amount of dust adhering to the PCB board during the cutting process.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
